Description

The present invention relates to a combined cooking device for heating an object to be heated such as a pot placed on a top plate, and a control program for the combined cooking device.

There are roughly three types of cooking cookers in view of the environment in which they are used.
One of them is the so-called "built-in type", which is installed in kitchen furniture such as a kitchen counter.
The second is a "stationary type" that is used by placing it in a predetermined position of kitchen furniture like a gas table (also referred to as a "gas combustion type table").
The third is a small and portable "tabletop type" that is placed and used at an arbitrary position on a table or the like.

Since the "built-in type" cooker is installed inside the kitchen furniture, the external dimensions must be designed according to the standard of general kitchen furniture, and the "stationary type" and "desktop type" can be used. The degree of freedom in design is much less than that of other products, and the difficulty of making a practical product is high.

Some built-in cookers are equipped with a grill (also referred to as an "oven chamber" or "heating chamber") that is heated by an electric heater inside the main body so that the range of cooking can be expanded. In the grill storage, a door provided on the front surface can be opened, an object to be heated such as fish can be inserted, the door can be closed, and the grill can be heated by the radiant heat of the electric heater for cooking (see, for example, Patent Document 1). ..

Further, conventionally, a compound type cooking cooker having two different heating methods, induction heating and microwave heating, has been proposed (see Patent Document 2). In addition, using two different heating methods, three heating modes can be selectively selected: induction heating in the ceiling of the cooking device, induction heating in the heating chamber, and microwave heating in the heating chamber. A composite heating cooker has also been proposed (see Patent Document 3).
However, the techniques shown in these two patent documents are premised on the "stationary type" in which the outer shell size and shape of the cooking device can be determined much more freely (compared to the built-in type).

On the other hand, in a cooking device, various proposals have been made conventionally for an input operation unit that greatly affects the usability of the user and a display unit that displays the input operation result or a cooking menu that can be cooked to the user. .. In particular, those equipped with two or more types of heating sources are roughly classified into a type in which an input operation unit and a display unit are installed for each heating source, and a type in which a display unit and an input operation unit common to the two heating sources are prepared. To.

As mentioned above, there are many restrictions on the dimensions and shape of the outer shell of the cooking cooker in the built-in type composite cooking cooker, so the type in which a common display unit and input operation unit are provided for the two heating sources has become the mainstream. (See Patent Documents 4 to 7).

Japanese Unexamined Patent Publication No. 2008-53075 (Page 5, FIG. 8) Jikkai Sho 53-44345 (Page 1, Figure 2) Japanese Patent Application Laid-Open No. 52-37242 (Page 1, FIG. 1) Japanese Unexamined Patent Publication No. 2017-172940 (Page 1, FIG. 1) Japanese Unexamined Patent Publication No. 2013-181707 (Page 1, FIG. 4) JP-A-2015-194289 (Page 1, FIG. 3) Japanese Unexamined Patent Publication No. 2016-072079 (1st page, FIG. 9)

In the conventional built-in type cooking cooker, an induction heating source and a radiant electric heater are provided in combination. A heating chamber equipped with a gas burner and a radiant electric heater has also been proposed. However, none of them has been put into practical use using microwave heating. As a background to this, when using microwaves, it is necessary to overcome some difficult technical problems such as prevention of microwave leakage.
For example, in order to realize microwave heating inside the heating chamber, a microwave oscillator typified by a magnetron, a cooling fan for cooling the oscillator, a waveguide for guiding microwaves to the inside of the heating chamber, and microwaves are used. Important electrical parts, structures, etc. such as an antenna device that diffuses into the heating chamber are required, but these structures are difficult to miniaturize due to the nature of handling microwaves, and electric heaters, gas burners, etc. It is necessary to take measures peculiar to microwaves, which have different properties.

With heating using microwaves, the food to be cooked can be heated from the inside at a high speed, so it can be used for cooking that cannot be achieved with heating sources such as gas burners, radiant electric heaters, and induction heating heaters. , Is expected to be used. However, since the heating characteristics of microwaves are significantly different from those of gas burners and induction heating, unless the input operation unit and display unit provide timely and appropriate information to the user, the user's operability and convenience will be impaired and the speed will be increased. There is a concern that it will interfere with cooking. In addition, there is a concern that it may lead to the cause of cooking failure and damage the user's expectations.

A first object of the present invention is to propose a cooking cooker that can use an oven heating source of induction heating, radiant or heat transfer type, and a microwave heating source, and further provide an input operation unit and a display unit. By sharing it, it is necessary to obtain a highly convenient composite cooking device that can be widely used for various types of cooking.

A second object of the present invention is to provide a control program for a computer suitable for a combined cooking device that solves the above-mentioned problems.

Embodiment 1.
1 to 39 show the built-in type composite cooking apparatus according to the first embodiment. In the following description, unless there is a particular contradiction, it is simply referred to as a "cooker".
In each figure, the reference numeral RT indicates the right direction of the cooking device 1, and LE indicates the left direction. FT indicates the front and BK indicates the rear.

In the first embodiment, the "induction heating cooker" means a device having a heating unit based on the principle of induction heating. When there are a plurality of heating units, there may be a heating source of a method different from the induction heating method, for example, a heating source of another method such as a radiant electric heat source.

In the first embodiment, the "composite type cooking device" is provided with a heating source having a different heating principle in addition to the microwave heating source, and is heated in one heating chamber by these two or more heating sources. It means something that can be cooked. For example, one heating chamber is heated by a radiant electric heat source such as a sheathed heater or a mica heater, and the inside of the heating chamber is heated by microwaves, which is a kind of "composite type cooking cooker". ..

In the first embodiment, the "heating means (referred to as" oven heating source "in the following description)" of the heating chamber means that the wall surface of the heating chamber is installed in the heating source for heating from the outside and the internal space of the heating chamber. Any of the heating sources used may be used.
Further, it may be in any form in which a heat generating member that becomes high in temperature by an induction heating method is arranged, and the wall surface of the heating chamber is heated from the outside by the heat generating member, or the air in the heating chamber is heated.

For example, in Japanese Patent Document No. 2017-74305, a second cooking dish is placed in a heating chamber (grill storage) on which a cooking dish is placed, and the cooking dish is heated from below. A cooking device including a heating body (induction heating coil) and a third heating body (induction heating coil) for heating an object to be cooked from the side has been proposed.

Further, in Japanese Patent Application Laid-Open No. 2016-85996, an electric insulator is provided above and below the heating chamber, and an induction heating coil (IH coil) is provided in the space below the electric insulator. A configuration has been proposed in which a cooking plate placed on top is induced and heated. The cooking plate is made of a material that can be induced and heated, and for example, iron, stainless steel, a carbon material having a carbon content of 90% or more, and a ceramic material containing Si (silicon) or FeSi (ferrosilicon) as a conductive material are used. Has been done.

Further, as a typical example in which a heat generating member that becomes high temperature by an induction heating method is arranged, Japanese Patent Application Laid-Open No. 2005-071695 supplies a high frequency current to an IH coil to generate a high frequency magnetic flux in the IH coil. A high-frequency magnetic flux can be linked with a heater arranged in the heater to allow an induced current to flow in the heater, and the Joule heat generated by the electric resistance of the heater itself can be used to heat the cooked food in the heater. It has been disclosed.

Further, in Japanese Patent Application Laid-Open No. 2013-247048, a heater having a closed circuit is electrically arranged inside the heating chamber, and a high frequency magnetic flux generated from an IH coil arranged outside the heating chamber is chained to this heater. It has been proposed to mix and heat the heater to a high temperature to dissipate heat in the heating chamber. The heater referred to here electrically forms a closed circuit, and a round bar or round pipe made of stainless steel or high nickel alloy is bent into a predetermined shape, and both ends are joined to each other by welding or brazing. It was formed in an endless shape.

In the "IH coil" referred to in the first embodiment, as a typical example, about 30 thin copper wires or aluminum wires of about 0.1 mm to 0.3 mm are bundled, and a plurality of these bundles are twisted. It is configured by winding it in a spiral shape (for example, Japanese Patent Document No. 2012-79580).

Further, Japanese Patent Application Laid-Open No. 2018-32551, which is another patent document, proposes an induction heating cooker in which an annular conductor formed in a ring shape with a flat plate-shaped conductive material is used as a heating coil.
Any of these forms corresponds to the "IH coil" which is the main part of the induction heating source.

In the first embodiment, "cooperative cooking" means two types of heating in which the heating location for one object to be cooked (including food, meat, vegetables, etc.) is different and the heating operation conditions can be set independently. Cooking that uses a source.

The above-mentioned "cooperative cooking" corresponds to the case where a plurality of heating sources are used with a time lag. For example, in the process of completing one cooking, after microwave heating is finished and preheating is performed, the object to be cooked is moved to another place, and at the place after the movement, the cooking is completed by heating with the IH coil 17L described later. The case is a kind of "cooperative cooking" here.

Cooperative cooking is proposed in the form of a built-in type cooking cooker in Japanese Patent No. 5833699 and Japanese Patent No. 5500944.

In FIGS. 1 to 38, the cooker 1 of the first embodiment is, for example, a cooker incorporated in kitchen furniture (including furniture called a system kitchen) 2 with a sink. 2A is an installation port formed in the kitchen furniture 2. As will be described later, the heating cooker 1 is supplied with AC power having a voltage of 200 V and a frequency of 50 Hz or 60 Hz from a commercial power source 99.

As shown in FIGS. 1 and 13, the cooking cooker 1 of the first embodiment has two induction heating portions on the left and right.
In FIG. 13, CL1 indicates a center line passing through the left and right center points of the upper unit 100 in the front-rear direction, and AL indicates a range in which the top plate 15 is exposed on the upper surface of the upper unit 100.

17HR is a right heating portion provided in the range on the right side from the center line CL1, and induction heating can be performed directly above this portion.
17HL is a left heating portion provided in the range on the left side from the center line CL1, and induction heating can be performed directly above this portion. As described above, the cooking device 1 is a cooking device in which two (two) "heating ports" are provided on the upper surface of the top plate 15.

For example, another induction heating unit may be provided between the right heating unit 17HR and the left heating unit 17HL so as to straddle the center line CL1.
In the following description, 17H is used as a reference code when referring to the “induction heating unit”.

Circular position marks 17LS and 17RS are provided on the upper surface of the top plate 15 to indicate a desirable position on which a heated object such as a metal pot or a plate (baked plate) is placed. By looking at the circular position marks 17LS and 17RS, the user (user) of the cooking device 1 can recognize that the induction heating unit 17H is located at two positions on the left and right in the cooking device 1 of the first embodiment. The voice guide of the voice synthesizer 95, which will be described later, also allows the user to recognize that there are two induction heating portions on the left and right.

The position marks 17LS and 17RS are formed by printing. Immediately below the position marks 17LS and 17RS, induction heating coils (hereinafter referred to as "IH coils") 17L and 17R, which will be described later, are installed. The position marks 17LS and 17RS do not have to be circular, and for example, only the center point of a desirable position on which the object to be heated may be placed may be indicated by a figure, a symbol such as "+", or a character.

Since the position marks 17LS and 17RS are circular marks indicating reference positions that can be induced and heated by the IH coils 17L and 17R, they are drawn with a diameter slightly larger than the maximum outer diameter of the IH coils 17L and 17R. ..

Any one of the IH coils 17L and 17R may be replaced with a radiant electric heat source such as a radiant heater or an infrared heater. Alternatively, in addition to the IH coils 17L and 17R, a radiant electric heat source may be provided to have three or more heating units.

In the first embodiment, when the IH coils 17L and 17R are collectively referred to as an IH coil, the reference numeral 17 is used. Therefore, when it is called "IH coil" 17, it may be either the IH coil 17L on the left side or the IH coil 17R on the right side.

In the first embodiment, the "induction heating source" 9 refers to a configuration including the IH coil 17 and inverter circuits 81R and 81L described later.

As shown in FIG. 4, the cooking cooker 1 is supported by being placed on the upper surface 2P of the mouth edge portion of the installation port 2A. As shown in FIG. 2, in the first embodiment, the kitchen furniture 2 is provided with a water tank 2C capable of temporarily storing water discharged from the water supply port 2D of the water supply. Reference numeral 2B is a front opening formed at a predetermined position of the kitchen furniture 2. This front opening is for exposing the front surface components (door 114 and front cover 112, which will be described later) to the front when the cooking cooker 1 is incorporated.

If the size of the front opening 2B and the installation port 2A of the kitchen furniture 2 is standard, it is mostly pre-formed with standard dimensions because standardization is being promoted by the industry. be. This will be explained in detail later.

The usual method of incorporating the cooker 1 into the kitchen furniture 2 is as shown in FIG. FIG. 3 is a schematic diagram showing an intermediate stage of the work of incorporating into the kitchen furniture 2.
As shown in FIG. 3, the cooking cooker 1 is placed in the installation port 2A while the front side (front side) of the cooking cooker 1 is tilted downward, and then the rear side of the cooking cooker 1 is placed. Is lowered as shown by the solid arrow BD, the cooking cooker 1 is placed on the peripheral edge of the installation port 2A of the kitchen furniture 2.

After that, the screws are tightened to move (rotate) the fixing bracket (not shown) installed on the rear peripheral edge of the lower unit 100, which will be described later, and the fixing bracket is strongly pressed against the kitchen furniture 2. And the installation is completed. Since such an installation method has already been widely adopted, the detailed structure will not be described.

As shown in FIG. 3, the main body 110 of the heating cooker 1 is combined and integrated in a state where the upper unit 100 and the lower unit 200 are stacked one above the other, and such an integrated form is used. In the assembly work shown in FIG. 3, only the upper unit 100 is fixed to the kitchen furniture 2 with the screw. If the fixing bracket (not shown) is removed, the entire cooking cooker 1 can be taken out from the kitchen furniture 2. As a result, inspections and repairs can be performed outside the kitchen furniture 2 thereafter. In addition, when it is called a "main body" within the range of only the upper unit 100, it is distinguished by adding a reference numeral 10.

As shown in FIG. 2, the installation port 2A formed in the kitchen furniture 2 has a rectangular planar shape. However, the four corners are arcuate.
The width dimension W1 of the installation port 2A is 560 mm to 564 mm. Further, the dimension D1 in the front-rear direction is formed to be 460 mm to 464 mm.

In FIGS. 1 and 2, 3 and 4 are surface materials constituting the surface of the kitchen furniture 2. 5 and 6 are surface materials adjacent to both the left and right sides of the kitchen furniture 2 when the cooking cooker 1 is incorporated.
When the cooker 1 is incorporated in the kitchen furniture 2, the front surfaces of the surface materials 3 to 6 are substantially flush with the front surface of the cooker 1. In other words, when the cooking device 1 is incorporated, the surface materials 3 to 6 and the cooking device 1 can give the user a design feeling as if they are a unified flat surface.

In FIG. 3, FIG. 8 is a wall that divides the inside of the kitchen furniture 2 into a plurality of rooms at the top and bottom, and the lower part of the wall is often used as a storage for kitchen utensils, food, and the like. Note that the wall 8 is not shown in FIG. Further, the wall 8 may be installed inside the kitchen furniture 2 so as to be removable.

According to the configuration described above, when the cooking cooker 1 is incorporated in the kitchen furniture 2, the entire front surface of the kitchen furniture 2 exhibits a substantially one flat surface. When the user looks at the kitchen furniture 2, the front surface (front surface) is designed so that it can be recognized as a clean and unified design.

The kitchen furniture 2 and the heating cooker 1 do not have to be designed by the same manufacturer. The kitchen furniture is manufactured and sold by a kitchen furniture such as a sink and a housing equipment manufacturer, and the heating cooker 1 is manufactured and sold by a home appliance manufacturer. In many cases, it is manufactured and sold.

In FIGS. 1 and 2, reference numeral 7 is a frame line printed on the front surface of the surface materials 3 to 5, and does not form physical unevenness on the front surface of the surface materials 3 to 5. It should be noted that a thin decorative plate or tape made of glossy metal may be attached to indicate the presence of the frame line 7 to give a high-class feeling.

The four types of surface materials 3 to 6 may be the same. Further, these surface materials 3 to 6 do not have to move back and forth like doors and drawers. For example, it may be fixed on the surface of the kitchen furniture 2 and may not move at all.

If the front color and surface morphology (pattern, glossiness, unevenness, etc.) of the four types of surface materials 3 to 6 are unified, the unified design feeling of the kitchen furniture 2 is enhanced. For example, when the entire front surface of the surface material 4 is unified with a single color or wood grain design, the front surface of the surface material 3 may also be unified with the same single color or wood grain design.

Next, FIGS. 4 and 5 will be described. FIG. 4 is a schematic vertical cross-sectional view showing the dimensional relationship between the kitchen furniture 2 of FIG. 1 and the cooking utensil 1. FIG. 5 is a schematic vertical cross-sectional view showing an enlarged part of the front part of the kitchen furniture 2 shown in FIG.

In FIG. 4, 113 is a heating chamber, which will be described later, and is formed inside the lower unit 200. On the front surface of the heating chamber 113, an opening 113A (see FIG. 10) is formed in which a cooking utensil such as a frying pan and an object to be cooked can be taken in and out. The opening 113A is openably covered by a door 114 (see FIG. 10).

The front surface of the door 114 and the front surface of the front cover 112 are designed to be flush with each other. The door 114 is rotatably supported by a hinge 176 and an arm 116 (not shown) on the main body 110 so that the front surface thereof is flush with the front surface of the front cover 112 except for the handle portion 115. ing. Therefore, the door 114 functions as a "front opening" door that opens forward with its lower end as a fulcrum (center of rotation).

In FIG. 4, H1 is the maximum height dimension of the cooking device 1. That is, the dimension from the upper surface of the top plate 15 to the bottom surface of the lower unit 200 is 227 mm.

In FIG. 4, H2 is a height dimension from the lower end of the top plate 15 to the lower end of the front cover 112, and is 215 mm to 223 mm. H3 is a dimension from the upper end to the lower end of the front cover 112 or the door 114, and is set to 171 mm. H4 is a dimension of the top plate 15 in the height direction, and is 11 mm.

(Upper unit 100)
In the first embodiment, the upper unit 100 alone functions as the cooking device 1. Therefore, the commercial (alternating current) power supply 99 is supplied only to the upper unit 100. However, the power cord 106 (not shown) for directly connecting to the commercial power supply 99 via the plug 106A (not shown) is pulled out from the lower unit 200 to the outside of the cooking cooker 1.

The upper unit 100 includes a box-shaped upper case (upper housing) 16 constituting the outer shell of the main body 10 and a metal frame-shaped reinforcing plate (support frame) 22 fixed to the upper part of the upper case (FIG. 7) and a top plate 15 made of heat-resistant tempered glass or crystallized glass, which is superposed on the upper surface of the reinforcing plate 22 so as to cover substantially the entire surface except the rear portion. In other words, the main body 10 of the upper unit 100 includes an upper case 16 and a top plate 15 which are outer shells, respectively.

The upper case 16 is formed by pressing a thin metal plate such as a zinc steel plate. Alternatively, a plurality of thin metal plates are joined by spot welding or screws to form a box shape. In the first embodiment, as will be described later, the peripheral portion of one thin metal plate is vertically bent to form a bottom wall (bottom surface) 16S, a rear wall 16B, a front vertical wall 16F, and side vertical walls 16L, 16R. Each is formed integrally.

The upper case 16 may be formed in another form. For example, only three parts of the bottom wall (bottom surface) 16S, the rear wall 16B, and the front vertical wall 16F are formed by pressing one metal plate. Two side vertical walls 16L, 16R, one rear wall 16B and a front vertical wall 16F formed separately from this are attached later by screw or spot welding, and finally the entire upper surface is open in a box shape. Make it into a shape.

The top plate 15 is formed in a flat plate shape having a substantially uniform thickness as a whole, and the entire lower surface thereof is covered with a painted surface through which visible light does not pass. Therefore, the functional parts below the top plate 15, for example, the IH coils 17L and 17R, cannot be visually recognized from above the top plate 15.

The IH coil 17R has a donut-shaped planar shape. The maximum thermal power of this IH coil 17R is 3200 W. The maximum external dimension (diameter) is 168 mm.

The other IH coil 17L also has a donut-like shape. The maximum thermal power of this IH coil 17L is 3200W. The maximum external dimension (diameter) is 168 mm. The diameter may be expanded to about 180 mm so that it can be used for objects to be heated such as large pots and frying pans.

Reference numeral 18 is an opening (see FIG. 7) formed laterally long at the rear of the upper case 16, and reference numeral 19 is an exhaust cover installed above the opening, which is a shutter or a large number of penetrations for ventilation. A hole is formed. Reference numeral 20 is an exhaust port formed between the exhaust cover 19 and the opening 18.

Reference numeral 22 is a metal reinforcing plate fixed to the upper end portion of the rear portion of the upper case 16 as described above. The reinforcing plate 22 has a length equivalent to the width of the trailing edge of the upper case 16. Reference numeral 21 is a metal decorative frame fixed to the upper surface of the reinforcing plate 22. This decorative frame projects to the rear of the upper case 16 and is formed longer than the width of the upper case 16. That is, when viewed from above, it seems that the rear side of the exhaust cover 19 and both the left and right sides are surrounded in a series (see FIG. 6).

Reference numeral 25 denotes a metal decorative frame, which is installed so as to protect the left and right end faces and the front end faces of the top plate 15 from an external impact as shown in FIG.
Reference numeral 26 denotes an annular cushion material made of a highly elastic material such as silicon rubber, which is attached to the entire lower surface of the decorative frames 21 and 25. As a result, the upper unit 100 is placed on the kitchen furniture 2 via the cushion material 26. It should be noted that the design may be such that the three parts (sides) of the left and right end faces and the front end face of the top plate 15 or the four parts (peripheral four sides) including the rear end face are surrounded by one decorative frame 25.

In FIGS. 6 and 13, 31L is a left side display unit and 31R is a right side display unit. Reference numeral 30 is an integrated display unit, which is installed in the front portion of the top plate 15 and below the left and right center portions. 31L is a left side display unit, and 31R is a right side display unit. These left and right display units 31L and 31R are also installed on the left side of the front portion of the top plate 15 and below the right side.

The integrated display unit 30 and the left and right display units 31L and 31R are mainly composed of a liquid crystal display screen (not shown), and the integrated display unit 30 and the left and right display units 31L and 31R are input operation units. It is installed on the horizontal operation board 41 installed in the left-right direction on the 40. It should be noted that the lower surface of the top plate 15 is not provided with a painted surface that blocks visible light as described above, corresponding to the positions directly above the integrated display unit 30, the left and right display units 31L, and 31R. Therefore, the display contents of the integrated display unit 30, the left and right display units 31L, and 31R can be visually recognized from above the top plate 15.

The integrated display unit 30 displays common information and alarms of the cooking device 1. For example, the selection result of the three types of heating sources of the cooking device 1 and the caution information and the warning information indicating the operating state of the heating sources are displayed. That is, since the integrated display unit 30 may display information related to the three heating sources of the induction heating source 17, the oven heating source 188 described later, and the microwave heating source 189, the integrated display unit 30 may display information. It is called.

The left side display unit 31L displays information regarding the operation of the left side IH coil 17L. For example, as described later, when setting timer cooking, it can be set in 1-minute units, but the set time can be displayed. It also displays the elapsed time from the start of the heating operation and the "remaining time" until the timer set time ends. Furthermore, when preheating cooking is selected, the automatically set temperature (default temperature), the current temperature, and the like are displayed. The "remaining time" is displayed as 9 minutes 59 seconds from the stage when it becomes less than 10 minutes, and the remaining time is displayed in 1 second units.

Similarly, the right side display unit 31R displays information regarding the operation of the right side IH coil 17R. The right side display unit 31R basically displays various information such as the timer setting time of the left side IH coil 17L, the preheating temperature, and the elapsed time, similarly to the left side display unit 31L.

In FIG. 13, 40 is an input operation unit. The input operation unit 40 is arranged laterally long along the front end edge portion of the top plate 15 behind the front portion of the decorative frame 25.
The input operation unit 40 is arranged on the upper surface of an operation board 41 which is horizontally long and is installed in a strip shape.

Various electronic components and an integrated control device MC that controls the overall control of the cooking device 1 are mounted on the operation board 41. The input operation unit 40 will be described in detail later. The operation board 41 is made of a plastic material having excellent electrical insulation. The integrated control device MC is mounted on the inverter circuit board 80 of the upper unit 100.

Below the operation board 41, flat plate-shaped auxiliary support plates (not shown) are installed so as to be vertically overlapped with each other so as to face the operation board 41 with a gap. That is, it has a structure of two upper and lower layers (two sheets) facing each other at intervals, so that as many electric components and circuits as possible can be mounted.

F2 is a second air passage through which the cooling air from the second cooling fan 61 described later flows, and is formed by a space between the cover 70 described later and the front vertical wall 16F in front of the upper case 16. (See FIGS. 7 and 14).

In FIG. 7, reference numeral 16B is a rear vertical wall of the upper case 16. The lower case 101 and the upper case 16, which will be described later, are integrated with screws 51 at a plurality of places.

As is clear from FIG. 7, the rear vertical wall 16B of the upper case 16 and the lower case 101 face each other closely within a range of about 20 mm to 30 mm, and the facing portion is fixed by the screw 51. ..

In FIG. 7, 104 is a cavity having a large depth and flat area. The cavity 104 is a space from the lower surface of the bottom wall (bottom surface) 16S of the upper case 16 to the upper surface of the bottom plate 101U at the rear of the lower unit 200, which will be described later. BH indicates the depth (vertical) dimension of the cavity 104.

As is clear from the structure shown in FIG. 7, in the first embodiment, there is a flat upper case 16 (which constitutes the outer shell of the main body 10) in which the opening on the upper surface is closed by the top plate 15. ing. When the upper case 16 is placed on the lower case 101, which will be described later, the bottom wall 16S of the upper case 16 also serves as the ceiling surface of the lower case 101.

As described with reference to FIG. 7, the space where the distance between the bottom wall 16S of the upper case 16 and the bottom plate 101U of the lower case 101 is the largest is the cavity 104.
In the cavity 104, a waveguide 123 constituting a part of the microwave heating device 120 described later is arranged long in the left-right direction behind the heating chamber 113.
Further behind the waveguide 123, a housing case C154 of the power supply circuit board 127 on which circuit components for supplying electric power to the microwave heating control unit 130 are mounted is arranged long in the left-right direction.

The microwave heating control unit 130 is mainly composed of a microcomputer, and is mounted on the power supply circuit board 127 inside the case C154. In other words, the power supply circuit board 127 housed inside the case C also serves as a control board on which the microwave heating control unit 130 is mounted. Although such a control board and a power supply circuit board 127 may be provided separately, in the first embodiment, they are integrated in consideration of the installation space.

In FIG. 7, 101T is a front horizontal wall made of a metal plate provided on the front side of the lower case 101. The front horizontal wall 101T is formed by bending the upper end of the front plate 101F of the lower case 101 rearward.

Reference numeral 198 is a support metal fitting for connection formed of a metal plate, and includes a horizontal portion 198H and a vertical portion 198V. The horizontal portion 198H is fixed to the front horizontal wall 101T of the lower case 101.

The vertical portion of the support metal fitting 198 and the front vertical wall 16F of the upper case 16 face each other closely within a range of about 20 mm to 39 mm, and the facing portion is fixed by a screw 51F (not shown). There is. Note that the screw 51F is not shown in FIGS. 8, 9 and 10.

Even if one or both of the upper case 16 and the lower case 101 have a box shape formed of a thin metal plate, the upper case 16 and the lower case 101 are firmly connected to each other by fastening the screws 51 and 51F. It becomes two box-shaped structures. In other words, since the external dimensions of the box-shaped upper case 16 are slightly smaller than the inner dimensions of the lower case 101, the upper case 16 is fitted into the lower case 101 in a range (depth) of about 20 mm to 30 mm. It fits. Instead of the screws 51 and 51F, other fastening means such as bolts and nuts may be used.

Even if the upper case 16 and the lower case 101 are made of a thin metal plate so as to be light, the fact that they are one strong box-shaped structure prevents microwave leakage in the part of the door 114 described later. It is beneficial to.

In particular, the top plate 15 of the upper unit 100 is supported by the upper surface of the kitchen furniture 2 and receives the full load of the lower unit 200, so that the upper case 16 and the lower case 101 as a whole are not distorted or deformed. Is important. Since the cushion 26 is attached to the entire circumference of the lower surfaces of the decorative frames 21 and 25, it is the cushion material 26 that actually contacts the upper surface of the lower part 2 of the kitchen.

In FIG. 7, reference numeral 80 denotes an inverter circuit board, which is installed in the central portion of the upper case 16. The inverter circuit board 80 is a rectangle whose planar shape is long in the left-right direction.

The inverter circuit 81 mounted on the inverter circuit board 80 includes an inverter circuit 81L that supplies high-frequency power to the left IH coil 17L and an inverter that supplies high-frequency power to the right IH coil 17R. It is composed of a circuit 81R and. These will be described later with reference to FIG.

A total of four aluminum heat sinks (heat sinks) 82 are attached to the upper surface of the inverter circuit board 80. As shown in FIG. 7, the heat sinks 82 are arranged in two rows so that the two heat radiation fins 82F face each other, and are installed close to each other to about several mm to 10 mm.

As can be seen from FIG. 7, the heat sink (heat dissipation sink) 82 has a power control switching element that constitutes a part of the inverter circuits 81L and 81R on inclined surfaces on opposite sides to each other. 83 is attached. Therefore, the heat generated during the operation of the electronic component 83 can be cooled by the cooling air passing around the heat radiation fin 82F.

The power control switching element 83 is, for example, an IGBT (insulated gate bipolar transistor). One of the power control switching elements 83 on the inverter circuit 81L side is the rear side of the heat sink 82 having two front and rear rows, and the power control switching element 83 on the other inverter circuit 81R side is the front side of the heat sink 82 having two front and rear rows. It is attached to the side. It may be attached to the opposite side.

In FIG. 7, reference numeral 70 denotes a cover made of a thin metal plate or a plastic material that covers the entire upper part of the inverter circuit board 80. The left and right end faces of the cover 70 are open, and as shown in FIG. 14, the left end face side of the cover 70 serves as the inlet FI of the cooling air RF1 described later, and the right end face side of the cover 70 serves the outlet FO of the cooling air RF1. Configure.

The cover 70 is located at a position where a constant gap (a linear distance of about several mm) is secured between the cover 70 and the lowermost surfaces of the IH coils 17L and 17R, and a constant gap is also secured with the uppermost surface of the heat sink 82. It is a size to secure.

Since the cover 70 is directly below the IH coil 17L and is in close proximity to the cover 70, if the cover 70 is expected to have a magnetic shielding effect, the cover is made of a metal such as aluminum, and the upper case is further formed. It is even better to connect to 16 electrically. For example, a screw (not shown) for attaching the cover 70 is set to reach the screw hole of the cover 70 directly. Since the upper case 16 is connected to the lower case 101, which will be described later, with a metal screw or the like, it is electrically connected to the ground terminal (not shown) provided in the lower case 101, and noise is absorbed by the ground. Ru. By doing so, the magnetic shield effect of the cover 70 can be expected to have a noise shielding effect on various electric components mounted on the inverter circuit board 80.

Further, if the cover 70 is injection-molded from a plastic material, the cross-sectional shape of the cover 70 can be determined relatively freely. Therefore, there is an advantage that the flow (direction) of the cooling air RF1 flowing through the first air passage F1 can be adjusted. For example, a rib-shaped wind direction plate or the like may be integrally formed on the lower surface of the cover 70 so that a large amount of cooling air RF1 flows particularly to a specific portion of the heat sink 82.

The coil base 17C may be provided individually for the two IH coils 17L and 17R, or may be formed by one structure in common with the two IH coils 17L and 17R.
The coil base 17C has a structure in which the coil base 17C is directly placed on the upper surface of the cover 70 and fixed to the cover 70 with a fixing tool such as a screw. Alternatively, an elastic body such as a compression spring is interposed between the cover 70 and the upper surface of the cover 70, and the cover 70 is supported in a form of being constantly pushed up toward the top plate 15. Detailed description of these support structures will be omitted. In any case, in the IH coils 17L and 17R, the facing distance (distance) from the back surface (lower surface) of the top plate 15 does not change for a long period of time. Therefore, during induction heating, the distance between the cooking container, which is the object N to be heated placed on the top plate 15, and the IH coils 17L and 17R does not change, so that the high frequency current is applied to the IH coils 17L and 17R. It is possible to suppress changes in the high frequency voltage and high frequency current generated in the inverter circuits 81L and 81R that supply the above, and to stabilize the induction heating performance.

The IH coils 17L and 17R are on one horizontal line (second horizontal line HL2). In other words, it exists on one plane (second horizontal plane HL2) determined by the second horizontal line (see FIG. 9).

The cover 70 is in a position where it is not in contact with both the coil base arranged below the IH coils 17L and 17R and the heat sink 82.

The cover 70 is fixed so as to be in close contact with the upper surface of the flat plate-shaped support plate 71, which is larger than the planar shape of the cover 70. Then, as shown in FIGS. 7 and 14, a first air passage F1 long in the left-right direction is formed between the inverter circuit board 80 and the cover 70.
The support plate 71 is made of an insulating material.

In FIGS. 7 and 10, 102 is a metal exhaust duct to which the exhaust flow from the lower unit 200 is guided. The exhaust port side end portion 102E of the exhaust duct 102 penetrates through the gap GP1 formed between the partition plate 52 described later and the rear vertical wall 16B of the upper case 16.

In FIG. 9, reference numeral 16A is a horizontal flange formed by bending the upper case 16 at right angles to the outside in a series from the upper ends of the side vertical walls 16L and 16R.
The 101A is a horizontal flange formed by bending the side vertical walls 101L and 101R of the lower case 101, which will be described later, in a series from the upper ends at right angles to the outside.

In the upper case 16 and the lower case 101, the flange 16A described above overlaps the flange 101A. In this polymerization state, the side wall surface of the upper case 16 and the side wall surface of the lower case 101 are fixed by the screw 51 (see FIG. 7) described above. Therefore, the upper case 16 and the lower case 101 are a strong integral structure by fixing with the screw 51 and closely fixing the flange 16A and the flange 101A. In other words, the total weight of the upper case 16 is received by the upper surface of the flange 101A of the lower case 101, so that even if the upper case 16 and the lower case 101 are formed of a thin metal plate, they are integrated. Then, it can be made into a box-shaped structure with mechanical strength.

The means for fixing the flange 16A and the flange 101A in an overlapping state may be other fastening means such as bolts and nuts instead of the screw 51. The flange 16A and the flange 101A do not come into contact with the upper surface of the kitchen furniture 2. Since the flange 16A and the flange 101A are made of a hard material (metal), there is a concern that the kitchen furniture 2 may be damaged. Further, if the flange 16A and the flange 101A hit the kitchen furniture 2, the cushion material 26 cannot be installed in a compressed state. If the cushion material 26 is not in close contact with the cushion material 26, there is a concern that the effect of preventing the intrusion of water or the like may be impaired.

As shown in FIG. 18, a first cooling fan 60 and a second cooling fan 61 are installed near the lateral vertical wall 16L on the left side of the upper case 16, respectively. The rotation axis (not shown) at the center of the rotary blades (not shown) of the first cooling fan 60 and the second cooling fan 61 extends in the vertical (vertical) direction, and the rotary blade has 1 Rotate on one horizontal plane (first horizontal plane HP1).

A centrifugal fan (blower) is adopted as the first cooling fan 60 and the second cooling fan 61. The reason for this is that the static pressure is high and the ventilation resistance is large in a space with a high mounting density. In general, there is also a type of centrifugal fan in which one suction port is provided and the blowing (sending) direction is the entire radial direction. However, the one of the first embodiment is a type having only one blowing direction.

In FIG. 18, 60A is an outlet formed integrally with the fan case 60C of the first cooling fan 60, and 61A is an outlet formed integrally with the fan case 61C of the second cooling fan 61. The outlet 60A is directed to the inverter circuit board 80. Further, the outlet 61A is directed toward the holder 42 below the operation board 41. That is, the two outlets 60A and 61A are both present on a common horizontal plane (HP1) and are directed to the right. This horizontal plane HP1 is a first horizontal plane described later.

The holder 42 is made of an insulating material, for example, a plastic material. The holder 42 has a size corresponding to the entire area of the input operation unit 40 and the range of the integrated display unit 30, the right side display unit 31R, and the left side display unit 31L, and is provided in a long strip shape in the left-right direction.

The first cooling fan 60 and the second cooling fan 61 have exactly the same structure, the same shape, and the same "rated specifications", and are assumed to be operated at the same rotation speed during normal induction heating operation. .. However, in the first embodiment, the number of rotations is changed by the IH control device 90 to change the amount of air blown. For example, when the driving power applied to the IH coils 17L and 17R is increased to increase the heating capacity, or when it is detected that the temperature of the integrated display unit 30 or the input operation unit 40 is higher than in normal times. In order to increase the cooling effect, the number of revolutions may be increased to increase the amount of air blown. Further, the first cooling fan 60 and the second cooling fan 61 may be operated at different rotation speeds due to measures against "beating noise" described later.

The rated specifications are, for example, rated voltage, operating voltage range, rated current, rated rotation speed, maximum air volume, maximum static pressure, sound pressure level, and the like. The rotation speed can be changed by changing the voltage applied or the voltage application time (on DUTY time) within the working voltage range.
On the other hand, in the first embodiment, the PWM control (Pulse Width Modulation) method is adopted, and the duty cycle (pulse width) of the pulse width is adopted according to the magnitude of the input signal (DC level). The motor of the first cooling fan 60 is controlled by changing the ratio of H and L). This PWM control is also adopted in the second cooling fan 61.

The first cooling fan 60 and the second cooling fan 61 have a configuration in which a rotary blade (not shown) is surrounded by fan cases 60C and 61C, and a circular suction port (not shown) is formed on the lower surface of the fan case. Not shown) is provided.

Vent holes 64 (FIG.) composed of a large number of round holes or elliptical holes at positions of the first cooling fan 60 and the second cooling fan 61 directly below the suction ports (not shown). 9). The ventilation holes 64 are formed on the bottom wall surface of the lower case 16. The ventilation holes 64 communicate with the ventilation holes 164 formed on the left side wall surface of the lower case 101, which will be described later. Therefore, the first cooling fan 60 and the second cooling fan 61 can introduce external air through the ventilation holes 164.

In FIG. 9, 165 is a recess (intake duct), and the ventilation hole 64 is provided to directly communicate with the ventilation hole 164 of the lower case 101. The recess 165 is formed by recessing it by a certain depth (dimension) DP1 from the left side. The dimension DP1 is 99 mm.

As shown in FIG. 9, an electric component mounted on the vertical center point of the outlet 60A of the first cooling fan 60, the vertical center point of the heat sink 82, and the upper surface of the power supply circuit board 55 described later. The vertical center point of 85 is at the position of one horizontal line HL1. In other words, the cooling air RF1 blown out from the outlet 60A of the first cooling fan 60 is in a positional relationship so as to reach the heat sink 82 and the electric component 85 when traveling straight to the right. The horizontal plane determined by the horizontal line HL1 is hereinafter referred to as "first horizontal plane" HP1.

AC power from the commercial AC power supply 99 is supplied to the power supply circuit board 55 via the filter circuit board 54 described later. Then, in the power supply circuit board 55, alternating current is converted to direct current. Therefore, an electric component 85 such as a diode for converting alternating current to direct current and a transformer 57 (not shown) is mounted.

When the temperature of the heat sink 82 of the inverter circuit board 80 rises abnormally, the IH control device 90 that controls induction heating reduces the heating amount of the IH coils 17L and 17R. In addition to this operation, the amount of air blown per unit time of the first cooling fan 60 may be temporarily increased. The temperature of the heat sink 82 is detected by contact-type temperature sensors TS8 and TS9 such as a thermistor.

When the first cooling fan 60 and the second cooling fan 61 have exactly the same structure, the same shape, and the same rated specifications, the procurement cost at the time of manufacturing can be reduced.
If cooling fans with the same specifications are arranged and operated in parallel, there is a high possibility that a growl noise will be generated. Therefore, in the first embodiment, as a measure against the roaring noise, the rotation speeds of the first cooling fan 60 and the second cooling fan 61 are controlled to have different values.

In FIG. 18, reference numeral 52 denotes a metal partition plate that is long left and right at the rear of the upper case 16 and is fixed to the upper case 16. The partition plate 52 is a wall extending vertically so as to partition the internal space of the upper case 16 in the front-rear direction. It should be noted that the term "partitioning" here does not mean a strict shielding that completely blocks the flow of air. The cooling air from the first cooling fan 60 and the second cooling fan 61 may be prevented from flowing backward to some extent beyond the upper end surface of the partition plate 52.

In FIG. 18, 52A is an exhaust window formed in the left half of the partition plate 52, and 53 is an exhaust port plate installed so as to cover the front side of the exhaust window 52A, and a large number of through holes 53A are formed. , The cooling air toward the exhaust window 52A of the partition plate 52 passes through. The cooling air that has passed through the exhaust window 52A is discharged to the external space of the cooking device 1 through the exhaust cover 19.

In FIG. 18, LF is an exhaust port dimension indicating a range (horizontal width dimension) of exhaust gas exhausted from the installation space CK of the IH coils 17L and 17R. The dimensions of the exhaust port are determined by the formation range of the through hole 53A and the width dimension of the exhaust window 52. When the width dimension of the exhaust window 52 is narrower than the formation range of the through hole 53A (the form shown in FIG. 18), the exhaust range LF is determined by the width dimension of the exhaust window 52.

In FIG. 18, reference numeral 54 denotes a filter circuit board arranged in the rear right corner of the upper case 16. In this filter circuit board, the noise in the power supply from the commercial power supply 99 is removed and supplied to the output terminal side, and conversely, the noise is prevented from flowing out (backflow) to the commercial power supply side on the input terminal side. It mounts electrical components (not shown) such as resistors and inductors (choke coils), line-to-line capacitors, relays, and current fuses. The end of the power cable (not shown) connected to the commercial power supply 99 via a plug is connected to the filter circuit board 54 via the inside of the lower unit 200 described later.

The power supply circuit board 55 is on the opposite side (right side) of the first cooling fan 60 with the inverter circuit board 80 interposed therebetween. In other words, since the power supply circuit board 55 is to the right of the outlet FO of the first air passage F1 formed between the inverter circuit board 80 and the cover 70, cooling immediately after exiting from the first air passage F1. Cooled by the wind.

In FIG. 18, CL3 is a center line passing through the center point of the left IH coil 17L in the front-rear direction, and CL4 is a center line passing through the center point of the right IH coil 17R in the front-rear direction.
CL5 is a center line that crosses each center point of the two IH coils 17L and 17R in the left-right direction. CL2 is a center line that penetrates the rotation centers of the rotary blades (not shown) in the first cooling fan 60 and the second cooling fan 61 in the front-rear direction. As is clear from FIG. 14, the first cooling fan 60 and the second cooling fan 61 are arranged in a straight line in the front-rear direction.

In FIG. 18, RF1 shows the cooling air blown from the first cooling fan 60. RF2 indicates the cooling air blown from the second cooling fan 61.

RF3 indicates the cooling air after exiting from the outlet FO of the first air passage F1. Further, RF4 indicates the cooling air after passing through the second air passage F2. A part of the cooling air RF3 after exiting from the outlet FO and the cooling air RF4 after passing through the second air passage F2 merge in the middle. That is, a part of the cooling air RF1 and the cooling air RF2 merge before reaching the through hole 53A of the exhaust port plate 53.

In FIG. 18, GP1 is a gap formed between the partition plate 52 and the rear vertical wall 16B of the upper case 16. The width of the gap GP1 in the front-rear direction is about 30 mm to 50 mm.

(Input display section)
Next, returning to FIG. 14, the main part of the input operation unit 40 will be described.
In FIG. 14, reference numeral 40 denotes an input operation unit formed on the front upper surface of the top plate 15, and as described below, input is made by utilizing a change in capacitance when the user lightly touches the top plate 15 with a finger or the like. Various input keys that can be used are arranged in a straight line in the horizontal direction.

The input operation unit 40 includes a right operation unit 40R, a center operation unit 40M, and a left operation unit 40L. Reference numeral 98 is an operation button or operation key (touch input type) of the main power switch 97 capable of supplying and shutting off the commercial power supply 99 described later. The operation button or operation key 98 is arranged at a position adjacent to the right end portion of the right operation unit 40R. The operation buttons or operation keys 98 will be described below on the assumption that they are within the range of the input operation unit 40 (see FIG. 14).

The main power switch 97 is attached to the filter board 54 of the upper unit 100 as shown in FIGS. 18 and 19. The commercial power supply 99 is supplied to the power supply circuit board 55, the inverter circuit 81, and the power supply circuit unit (not shown in FIG. 19) of the lower unit 200.

As shown in FIGS. 14 and 16, a total of five touch-type input keys 43R1 to 43R4 and 44R are arranged on the right operation unit 40R. These input keys 43R1 to 43R4, 44R are assigned one or a plurality of input functions as described below.

43R1 is an input key for selecting heating in the right heating unit 17HR. Further, the operation of the right IH coil 17R that has started the heating operation can be stopped. Therefore, when it is pressed once for the first time, it exerts a function of selecting the right heating unit 17HR, and when it is pressed once after that, it has a function of instantly issuing a stop command for the heating operation. As described above, each time the input key 43R1 is touched, the content that can be commanded to the IH control device 90, which will be described later, is automatically switched.

42R2 and 42R3 are a pair of input keys that specify the thermal power (power consumption) at the time of induction heating.
When you touch the input key 42R2 on the left side, the heating power is reduced by one step each time the operation is performed. For example, in the case of 3200 W (rated maximum thermal power: thermal power level 9), if the input key 42R2 is touched once, it becomes 2500 W (thermal power level: 8).

When you touch the input key 42R3 on the right side, the heating power is increased one step at a time for each operation. For example, in the case of a thermal power of 2500 W (thermal power level 8), 3200 W (rated maximum thermal power: thermal power level 9) can be selected by touching the input key 42R3 once.

43R4 is an input key for selecting a control menu for timer cooking. Timer cooking is a control method in which when a user sets a cooking time, an induction heating operation can be performed only during the set time. For example, when timer cooking is started by designating 10 minutes, a predetermined display is performed on the right side display unit 31R when 10 minutes have passed, and the voice synthesizer 95, which will be described later, automatically notifies the end of cooking by voice. It is done in. The induction heating is automatically stopped when the set time (for example, 10 minutes) has elapsed, but the induction heating time can be extended by performing an extension operation before the set time elapses.

The 44R is a touch-type input key for selecting a "control menu" for induction cooking, and one can be selected from a plurality of control menus each time a touch operation is performed. The "control menu" is a control mode of the induction heating source 9, in other words, a type of control, as shown in FIG. 25, such as boiling water, boiling food, and fried food (automatic cooking). That is, the driving time of the IH coil 17R, the heating power, the driving pattern for changing the heating power, and the like are different for boiling water, boiling food, fried food, and the like.

The "control menu" for the right heating unit 17HR is different from the name of the final cooked food or the name of the foodstuff obtained by induction heating. For example, "hamburger" and "tempura" are the names of cooked foods, not the "control menu" here. In other words, the "control menu" can be said to be a comprehensive expression of the type of heating, cooking method, conditions, etc. until the cooking is completed.

Next, the left operation unit 40L will be described with reference to FIGS. 14 and 17. The left operation unit 40L is provided with a total of five touch-type input keys 43L1 to 43L4 and 44L.

43L1 is an input key for selecting cooking by the left heating unit 17HL. Further, after the heating operation of the left IH coil 17L is started, the operation can be stopped at any time. That is, when it is pressed once for the first time, it exerts a function of selecting the left heating unit 17HL, and when it is pressed once after the induction heating is started, the heating operation can be stopped instantly.

43L2 and 43L3 are a pair of input keys that specify the thermal power (power consumption) in the left heating unit 17HL, similarly to the input keys 43R2 to 43R3 of the right operation unit 40R. Similar to the input keys 43R2 and 43R3 of the right operation unit 40R, each time the touch is made, the thermal power that has been increased by one step is selected or specified by one step in the specified thermal power value data table. You can choose the firepower of.

43L4 is an input key for selecting timer cooking. The input key 43L4 can specify the time for induction heating, similarly to the input key 43R4 of the right operation unit 40R. Further, at the end of timer cooking, the end of timer cooking is displayed on the left side display unit 31L as in the input key 43R4, and the voice synthesizer 95 also notifies the end.

44L is a touch-type input key that can select a "control menu" for induction cooking. Similar to the input key 44R of the right operation unit 40R, one control menu can be selected from a plurality of "control menus". The control menu that can be selected with the input key 44L on the left side is exactly the same as the control menu that can be selected with the input key 44R on the right side. As is clear from FIGS. 14 and 17, a total of five touch-type input keys 43L1 to 43L4 and 44L arranged on the left operation unit 40L are arranged in a straight line in the left-right direction.

In FIGS. 14 and 15, a total of 10 touch-type input keys are arranged on the central operation unit 40M. These input keys are assigned one or more input functions.
Hereinafter, 10 touch-type input keys will be described.

The input key 43KP on the far left is for setting various operations, displays, and the like of the entire cooking cooker 1 as desired by the user.

When the input key 43KP is pressed, the integrated control device MC described later switches to the "function mode", and the following "function setting menu" is displayed on the display screen 30D of the integrated display unit 30.
(1) Child lock setting (setting to disable operation of various input keys)
(2) Ventilation fan interlocking mode setting (3) Cleaning guide setting (cleaning time automatic notification function setting for heating chamber 113 and exhaust cover 19)
(4) Peak cut setting (Select one of the maximum power consumption of 5700W, 4800W and 4000W)
(5) Voice setting of voice guide (6) Volume setting of voice guide (7) Setting to prevent forgetting to take out cooked foods, cooking utensils, etc. from the heating chamber 113 (voice synthesizer 95 and integrated display unit 30) Necessity of alarm)
(8) HEMS registration setting (setting to use a power usage restriction device by a household power control device)
(9) Timer cooking time unit (1 minute unit setting changed to 5 minutes or 30 minutes unit) setting

By pressing the input key 43KP to switch the integrated display screen to the "function mode" and then operating the touch-type input keys 43M1 to 43M3 described later arranged in the central operation unit 40M, the "function" of the cooking cooker 1 can be operated. The above eight types of individual functions defined in the "setting menu" can be changed individually.

When the control mode and control conditions (temperature, thermal power, time, etc.) of the microwave heating source 189 and the oven heating source 188 are selected on the integrated display unit 30, the input key 43KP is used so as not to switch the function mode. The input function of is disabled. Therefore, the light emitting unit 27M1 corresponding to the input key 43KP does not emit light during the setting work of the control mode and the control condition (see FIG. 39).

For example, the setting of the peak cut value of the cooking device 1 will be described. Even if the default value at the time of shipment from the manufacturer is 5400 W, it can be set to either 4800 W or 4000 W when installed at the user's home. In this way, the function of the cooking cooker 1 can be changed according to the user's wishes, the usage environment (electric power situation of the installed home), and the like.

The 43MC is an input key for selecting a “cooperative cooking menu” to be described later, and is an input key for selecting cooking in the heating chamber 113 by the oven heating source 188 and the microwave heating source 189.

When the input key 43MC is operated, the integrated display unit 30 switches to a special display screen configuration. This point will be described later with reference to FIGS. 32 and 34 to 38.

The display screen 30D of the integrated display unit 30 is a single liquid crystal display screen on the hardware, but as shown in FIG. 15, a maximum of three display areas 30L and 30M are provided by the display unit drive circuit 63. It is displayed separately in 30R.

Of the three display areas, the display area 30L located on the left side is hereinafter referred to as "first area". The display area 30M located in the center is hereinafter referred to as a "second area". The display area 30R located on the right side is hereinafter referred to as a "third area". It should be noted that a method for displaying a single display screen by dividing it into a plurality of parts has been proposed, for example, in Japanese Patent No. 5425171 and Japanese Patent Application Laid-Open No. 2017-172940. Omit.

43M1 is a pair of left and right input keys for switching the screen displayed in the first area 30L of the display screen 30D. The information displayed in the first area 30L is selected by the display unit drive circuit 63 according to the display program of the integrated control device MC.

When the input key 43M1 on the left side of the two input keys 43M1 arranged side by side is operated, the display screen of the first area 30L moves forward, and the information displayed on the rear side is displayed in the center of the front and back. The display screen is switched according to the image to be displayed. That is, when the input key 43M1 on the left side is operated once, one of the desired display information can be selected from the display information group stored in the integrated control device MC. It should be noted that the display screen is viewed in a plane and does not actually move forward.

On the contrary, when the input key 43M1 on the right side is operated once, the display screen of the first area 30L moves backward, and instead, another information is displayed in the center of the front and back of the first display area. Then, the display screen is switched. That is, even if the input key 43M1 on the right side is operated, one of the "display information group" defined by the display program of the integrated control device MC is selected, but the selection direction (selection order) of the displayed information is selected. ) Is the opposite. The "display information group" here is a "control menu group" in the case of the first area 30L.

In this way, the user can display desired information from the display information group in the central portion of the first area 30L by operating either the input key 43M1 on the right side or the input key 43M1 on the left side. ..

43M2 is a pair of input keys for switching the screen displayed in the second area 30M of the display screen 30D. By operating any one of the input keys 43M2, the display information of the second area 30M can be sequentially switched one by one in the same manner as the input key 43M1.

43M3 is a pair of input keys for switching the screen displayed in the third area 30R of the display screen 30D. By operating any one of the input keys 43M3, the display information of the third area 30R can be sequentially switched one by one in the same manner as the input key 43M1.

The 43MS is a touch-type input key that can command the start of operation of microwave cooking and oven cooking using the heating chamber 113.
On the contrary, the 45MT is a touch-type input key that can stop the operation of microwave heating and oven heating. As is clear from FIG. 15, the ten input keys arranged in the central operation unit 40M are arranged in a straight line in the left-right direction.

When the operation key 98 of the main power switch is pressed to start cooking, the five touch-type input keys 43R1 to 43R4 and 44R do not always require an input function in the right operation unit 40R.

Similarly, in the left operation unit 40L, the five touch-type input keys 43L1 to 43L4 and 44L do not always need an input function. The same applies to the central operation unit 40M. In order to avoid unnecessary input such as when the user touches it without recognizing it, in the integrated control device MC, immediately after the heating cooker 1 is started, depending on the input process of cooking conditions, the progress of cooking, etc. Except for the input keys that require input, the input functions of other input keys are temporarily disabled to prevent input.

Therefore, in order to show that the input function of each input key as described above is effective, as shown in FIGS. 14 to 17, the light emitting display units 27R and 27L are used for each of the three operation units 40R, 40L and 40M. , 27M is provided.

As shown in FIGS. 14 and 16, in the right operation unit 40R, individual light emitting units 27R1 to 27R4 are arranged immediately behind the five touch-type input keys 43R1 to 43R4 and 44R. Since the input keys 43R2 and 43R3 are a pair, the individual light emitting units 27R2 share one.

The individual light emitting units 27R1 to 27R4 have one or a plurality of light emitting diodes arranged below the right operation unit 40R, and the display unit drive circuit 63 controls each individual light emitting unit 27R1 to 27R4 to emit light and turn off. LED. Alternatively, it is controlled to change the emission color.

For example, before the input key 43R1 (see FIG. 16) of the right operation unit 40R is operated, the individual light emitting unit 27R1 immediately behind the input key 43R1 emits blue light. As a result, it is displayed that the operation input can be accepted.

When the user operates the input key 43R1 and the integrated control device MC accepts the input, the individual light emitting unit 27R1 emits light in a unified color (red) to indicate that the user is accepting the operation. indicate. The control for this display is performed by the display unit drive circuit 63 based on the command of the integrated control device MC. It should be noted that instead of emitting light with one color, for example, the emission color may be changed from blue to red to indicate to the user that the operation is being accepted. This also applies to the individual light emitting units 27M1 to 27M6 and 27L1 to 27L4, which will be described later.

It should be noted that even in a method in which the individual light emitting unit 27R1 immediately behind the input key 43R1 is not emitted before the input key 43R1 is operated, the light emission is started when the operation is accepted, and the light emission is continued. good. In addition, a method may be adopted in which only the fact that the operation input is possible is indicated by light emission in advance (the stage before the operation), and the acceptance of the operation input is not displayed by light. Further, a form may be adopted in which the operation input is possible and the operation input is blinked in the state of waiting for the input, and the operation input is changed to continuous light emission at the acceptance stage.

Similarly, as shown in FIGS. 14 and 17, in the left operation unit 40L, the individual light emitting units 27L1 to 27L4 are arranged immediately behind the five touch-type input keys 43L1 to 43L4 and 44L. Since the input keys 43L2 and 43L3 are a pair, the individual light emitting units 27L4 share one.

The individual light emitting units 27L1 to 27L4 have one or a plurality of light emitting diodes arranged below the left operation unit 40L, and the display unit drive circuit 63 causes the individual light emitting units 27L1 to 27L4 to have a unified emission color. Light emission and extinguishing are controlled. Further, a form may be adopted in which the operation input is possible and the operation input is blinked in the state of waiting for the input, and the operation input is changed to continuous light emission at the acceptance stage.

Similarly, as shown in FIGS. 14 and 15, in the central operation unit 40M, the individual light emitting units 27M1 to immediately behind the ten touch input keys 43KP, 43MC, 43M1 to 43M3, 43MS, 43MT. 27M6 is arranged.

The individual light emitting units 27M1 to 27M6 have one or a plurality of light emitting diodes arranged below the central operation unit 40M, and the display unit drive circuit 63 causes the individual light emitting units 27M1 to 27M6 to have a unified emission color. Light emission and extinguishing are controlled. Further, a form may be adopted in which operation input is possible and blinks when waiting for input, and changes to continuous light emission when the operation input is accepted. It will be described in detail later with reference to FIG. 39.

The pair of input keys 43M1 share one individual light emitting unit 27M3. Since the two input keys 43M2 and 43M3 are also paired with each other, the individual light emitting units 27M4 and 27M5 are shared one by one. In the following description, when the individual light emitting units in the central operation unit 40M are generically referred to, the reference numeral 27M is used.

An individual light emitting unit 27R5 is also arranged directly behind the operation key (or operation button) 98 of the main power switch 97, which is located adjacent to the right end portion of the right operation unit 40R.

It is desirable that the light emission modes (continuous light emission, blinking, light emission color, etc.) of the light emission display units 27R, 27L, and 27M as described above are unified among the three operation input units in order to avoid unnecessary confusion and misunderstanding by the user.

In order to show that the input function of each input key is effective, there is also a method of making the operation unit of the input key emit light, but in that case, the light emitting unit is arranged directly under the operation unit of the input key and the operation unit is concerned. It is also necessary to manufacture the material with a light-transmitting material, and there is also a problem of ensuring the sensitivity of the operation unit of the input key, so that there are many problems in terms of structure and cost. Therefore, in the first embodiment, as described above, the light emitting display units 27R, 27L, and 27M are provided at adjacent positions while avoiding the operation unit of the input key. The term "adjacent" as used herein means a positional relationship in which the input key 43R1 and the light emitting display unit 27R are close to each other from the user's point of view and the one-to-one relationship can be instantly understood, such as the relationship between the input key 43R1 and the light emitting display unit 27R. .. Therefore, for example, the case where the input key 43R1 and the light emitting display unit 27R are partitioned by a structure such as a wall protruding upward with respect to the surface of the input key 43R1 is excluded.

In FIG. 14, thermal power display units 67L and 67R are provided at rear positions of the right operation unit 40R and the left operation unit 40L so as to indicate the thermal power stage during induction heating cooking.
These thermal power display units 67L and 67R indicate the thermal power stages in the right heating unit 17HR and the left heating unit 17HL by light emission (red). Nine stages from the rated minimum thermal power (thermal power level 1: 150 W) to the rated maximum thermal power (thermal power level 9: 3200 W) are shown by light.

The thermal power display units 67L and 67R are composed of a plurality of light emitting diodes (LEDs) installed in the space below the right operation unit 40R and the left operation unit 40L. The emission color may be changed depending on the magnitude of the thermal power. In the first embodiment, for example, the thermal power levels 1 and 2 are configured as follows.
(1) (Minimum) Thermal power level 1: 1 red lighting, 8 remaining blue lighting (2) Thermal power level 2: 2 red lighting, 7 remaining blue lighting In addition, the left end of the thermal power display units 67L, 67R The heat insulation display unit that emits light and displays the LED when operated in the "heat insulation mode" (see "display screen 3A" in FIG. 34) in which the object to be heated is heated with a thermal power smaller than the minimum thermal power level 1. 67H is provided.

On the left display unit 31L, the thermal power level value of the left heating unit 17HL is displayed by numbers 1 to 9. "1" is displayed when the minimum firepower level is 1, and "9" is displayed when the maximum firepower level is 9. The thermal power display on the left display unit 31L matches the thermal power stage displayed by the thermal power display unit 67L, and is displayed at the same timing.

Further, also in the right display unit 31R, the thermal power level value of the right heating unit 17HR is displayed by numbers 1 to 9. The display conditions are exactly the same as in the case of the left display unit 31L.

As can be seen from FIG. 14, the three light emitting display units 27L, 27M, 27R and the two thermal power display units 67L, 67R are arranged in a straight line in the left-right direction. Moreover, the three light emitting display units 27L, 27M, 27R and the two thermal power display units 67L, 67R are arranged in parallel in the left-right direction.

In this way, the three light emitting display units 27L, 27M, 27R and the two thermal power display units 67L, 67R are on a straight line in the left-right direction behind the three input operation units 40L, 40M, 40R. Because it is lined up in, operability and visibility are good. Further, the integrated display unit 30, the left side display unit 31L, and the right side display unit 31R are also arranged in a straight line in the horizontal direction, and the entire operation is performed from the viewpoint of the user who operates while standing on the front side of the cooking cooker 1. It has a good design and visibility.

In FIG. 14, 68 is a heating source display unit arranged behind the integrated display unit 30.
Since the heating source display unit 68 uses a plurality of heating sources by using the central operation unit 40M, the heating source that is actually operating is displayed by the LED light.

The heating source display unit 68 is composed of three display units. The leftmost display unit 68L is a display unit indicating that the microwave heating source 189 is used, and the character "range" is displayed in the vicinity of the front side, so that microwave heating can be easily performed. I'm trying to understand.

The central display unit 68M is a display unit indicating a case where "grill cooking" is performed in the heating chamber 113 using either or both of the upper heater 163A and the lower heater 163B. "Grill" is written on the front side so that it can be easily understood that the food is grilled.

The rightmost display unit 68R is a display unit indicating the case where "oven cooking" is performed in the heating chamber 113 using either or both of the upper heater 163A and the lower heater 163B.

Unlike grill cooking, "oven cooking" grasps the temperature in the heating chamber 113 and reflects (feeds back) it to the energization control of the upper heater 163A and the lower heater 163B. These will be described in detail later. In the vicinity of the display unit 68R on the far right side, the indication "oven" is displayed so that it can be easily understood that the cooking is done in the oven.

In FIG. 14, reference numeral 69 denotes a high temperature notification unit provided immediately behind the heating source display unit 68. The high temperature notification unit 69 causes the LED light emitting unit to emit light based on a command from the integrated control device MC, and displays that the temperature monitoring target portion is at a high temperature.
As will be described later, the integrated control device MC commands high temperature notification based on the temperature information from the temperature detection circuit 93 that receives the temperature detection signals from various temperature sensors and the heating chamber control unit 159.

Although not shown in FIG. 13, the high temperature notification unit 69 defines three temperature monitoring target portions: the left heating unit 17HL, the heating chamber 113, and the right heating unit 17HR, as shown in FIG. The status of these temperature monitoring target parts is displayed individually. Therefore, for example, after induction heating cooking in the left heating unit 17HL, it is possible to notify the user that the temperature in the range from the center to the left side of the top plate 15 corresponding to the left heating unit 17HL is high.

Returning to FIG. 13, 46L and 46R are windows for transmitting an infrared signal as a command signal for starting operation to a ventilation device (not shown) installed outside. Below this window, an infrared transmitter 48 (see FIG. 19) is installed. Actually, the windows 46L and 46R are covered with an inconspicuous surface sheet so as not to be visible from above the top table 15. The sheet is, of course, made of a material that transmits infrared signals.

In FIG. 13, reference numeral 49 denotes a wireless communication unit (communication module), which includes an antenna (not shown) and a transmission / reception circuit (not shown) that receive radio waves from the outside and transmit radio waves to the outside. .. The wireless communication unit 49 is installed below the right end of the display board 41 at a slight distance from the bottom surface of the upper case 16.

Next, the control means of the upper unit 100 will be described with reference to FIGS. 19 and 20.
In FIGS. 19 and 20, the description of a partial configuration is omitted, and the filter circuit of the filter circuit board 54 is not described.

FIG. 19 shows the control means of the upper unit 100 and the control means of the lower unit 200. In FIG. 20, only the main control means in FIG. 19 is extracted, and the transmission / reception of control command signals, the power supply relationship, and the like are indicated by arrows.

In FIG. 19, reference numeral 97 denotes a main power switch that is opened and closed by the user, and is connected to a 200 V commercial power supply 99 via a power cord and a power plug (not shown). Reference numeral 91 is a power supply circuit to which electric energy is supplied via the main power supply switch 97, and reference numeral 92 is a direct current power conversion unit for converting AC power from a commercial power source into direct current. The power supply circuit 91 is mounted on the power supply circuit board 55.

The MC is an integrated control device and has the function of a main controller or a host computer. It is a control device mainly composed of a microcomputer. A predetermined constant pressure current is supplied to the integrated control device MC from the power supply circuit 91. Further, the integrated control device MC is mounted on the back (lower) surface of the operation board 41 (see FIG. 18).

The integrated control device MC is composed of four parts, an input unit, an output unit, a storage unit, and a CPU (arithmetic control unit), and the storage unit stores the energization control programs of the three heating sources in advance. It is (stored). Further, apart from the storage unit (ROM, RAM) of the microcomputer, a large-capacity storage device (main memory) MM for recording abnormality monitoring information is built in.

Reference numeral 90 denotes an IH control device that controls control during induction heating, and is mainly composed of a microcomputer. The IH control device 90 stores (stores) in advance an energization control program corresponding to various cooking menus at the time of induction heating. It also has a built-in storage device (not shown) that records abnormality monitoring information.

A second IH control device 90A (not shown) may be in charge of a part of the function of the IH control device 90. For example, a microcomputer may be mounted on the inverter circuit board 80, and the microcomputer may be in charge of input and output control of the inverter circuits 81L and 81R.

During all cooking operations such as induction cooking and microwave cooking, the presence or absence of an electrical abnormality is centrally monitored by the integrated control device MC.

Reference numeral 96 denotes a clock circuit also called a real-time clock, which is supplied with power from a dedicated power supply (built-in battery) BT1 different from the power supply circuit 91 connected to the main power supply switch 97 and is driven for a long period of time. It has become so. This may be, for example, a radio-controlled clock, which always informs the current date and the exact time in seconds if requested by the integrated control device MC, and is set to the correct date and time at the manufacturing stage of this cooking cooker 1. There is. Therefore, even if the main power of the cooking cooker 1 is turned off and then turned on again, the time information of this clock circuit is not affected, and there is a function of always transmitting the latest correct time to the integrated control device MC. Therefore, the abnormality monitoring information recorded in the storage device MM of the integrated control device MC is always recorded and stored at the same time with an accurate time.

In FIG. 19, reference numeral 72 denotes a power control unit (also referred to as a “demand control unit”). The power control unit 72 analyzes a command signal for performing induction heating or microwave heating by the integrated control device MC, and sets the total power consumption of the heating cooker 1 to a specified value or an upper limit value individually set by the user. There is a function to monitor so that it does not exceed, and there is a function to automatically limit the thermal power during induction heating or microwave heating so that the total power consumption does not exceed the specified value or the arbitrarily set value.

Generally, the "demand control device" or "demand control device" is a device that controls the value of demand (power demand), automatically checks the power usage status, and if it is likely to exceed the set value. If you set the automatic stop of the device that can be stopped by notifying with an alarm etc., the device itself will automatically stop the electric device that can be stopped as determined, and after a certain period of time, the electricity will be stopped. It is known to automatically restore the equipment, and it is said that it will be very effective in managing the contracted power with the power company in each household.

The electric power control unit 72 of the first embodiment is provided so that the cooking cooker 1 itself has the above-mentioned power consumption suppressing function. The power control unit 72 may be provided as a control function in the integrated control device MC without providing special hardware, and a control program for demand may be incorporated in the integrated control device MC from the beginning, or may be provided. It can be realized even if it is added later.

The power control unit 72 of the first embodiment can set the maximum power consumption of the entire cooking cooker 1 from three stages (5700W, 4800W, 4000W). It should be noted that this setting can be set in the input operation unit 40 while observing the above-mentioned three-step numerical values displayed on the integrated display unit 30 when a plurality of specific keys in the input operation unit 40 are pressed at the same time. .. Such a simple setting method is introduced, for example, in Japanese Patent No. 6012780. As described with reference to FIGS. 14 and 15, when the input key 43KP of the central operation unit 40M is pressed, the integrated control device MC switches to the “functional mode”, and the display screen 30D of the integrated display unit 30 displays “peak”. Since the display that allows "cut setting" and "HEMS registration setting" is displayed, the total power consumption of the cooking device 1 as described above can be easily suppressed.

Reference numeral 73 is a signal transmission unit provided for transmitting various control signals between the upper unit 100 and the lower unit 200. For example, signal lines and connectors that can transmit signals by wire are applicable. Further, for example, an infrared communication unit may be used so that signals can be exchanged wirelessly. The signal transmission unit 73 is also provided between the integrated control device MC and the IH control device 90.

The IH control device 90 obtains temperature information from the temperature detection circuit 93 and monitors whether or not the main part of the upper unit 100 has an abnormally high temperature. For example, electronic parts and semiconductor parts corresponding to the various input keys 43M1 to 43M3, 43MS, 43MT and the like are arranged in the central operation unit 40M, but since these parts are relatively sensitive to heat, a predetermined temperature is provided. It is monitored through the temperature detection circuit 93 so as not to exceed (for example, 60 ° C.).

The IH control device 90 determines that the measured temperature is in the "abnormal preliminary state" when the temperature exceeds the predetermined temperature. The abnormal preliminary state is limited to the case where the detection temperature is in the range of 60 ° C to 65 ° C. If the temperature exceeds 65 ° C., the risk increases, and the control device 90 recognizes it as a true abnormal condition.

In this abnormal preliminary state, the induction heating operation does not stop immediately, and control is performed to reduce the thermal power of the induction heating. However, when the temperature exceeds 65 ° C., an abnormal state is determined by the IH control device 90, and the induction heating operation is immediately stopped. Specifically, for example, when the driven IH coil is the right side IH coil 17R, the power supply of the inverter circuit 81R that supplies high frequency power to the IH coil 17R is cut off. Then, the operation of the induction heating circuit 94R including the IH coil 17R and the capacitor for resonance is stopped. Note that 94L is an induction heating circuit for the left IH coil 17L.

Even if it is improved by increasing the blowing capacity of the motor 61M of the second cooling fan 61 that cools the IH coil installation space CK of the upper unit 100 while maintaining the thermal power of the induction heating in the above-mentioned abnormal preliminary state. good. Further, it may be used in combination with a measure for lowering the thermal power of induction heating.

Then, at least, the state of change in electrical and physical (as an example, the temperature of the central display unit 30 described above) at the time of induction heating during the period from the abnormal preliminary state to the emergency stop is shown (abnormality monitoring). The information is stored in the storage device 90R of the IH control device 90.

In the above-mentioned abnormal preliminary state, the induction heating operation does not stop immediately, and the ventilation capacity of the motor 61M of the second cooling fan 61 is not increased (the rotation speed of the rotary blade is not changed), and the IH coil 17L. The thermal power of 17R may be improved by forcibly lowering it.

The abnormality monitoring information stored in the storage device of the IH control device 90 is acquired during the period from the time when the start command is received from the integrated control device MC until the cooking is normally completed. Therefore, the above-mentioned "control menu" (for example, "boiler", "simmered", "fried food", etc. in the case of the left operation unit 40L) and information on the thermal power of induction heating are also recorded in chronological order. If an emergency stop occurs due to an abnormal state on the way, the abnormality monitoring information will be stored in the storage device 90R up to that point.

Further, in the first embodiment, in order to monitor the operation of the cooking cooker 1 over a wider range and acquire data, after turning on the main power switch 97, all the heating on the upper unit 100 and the lower unit 200 side is performed. The integrated control device MC has acquired the monitoring information regarding the cooking state. The integrated control device MC acquires monitoring information for the presence or absence of an abnormality from the heating chamber control unit 159 and the microwave heating control unit 130 via the signal transmission unit 73.

In the inverter circuit board 80, an inverter circuit 81R dedicated to the IH coil 17R on the right side and an inverter circuit 81L dedicated to the IH coil 17L on the left side are mounted one by one.

The two inverter circuits 81L and 81R are driven independently of each other by the IH control device 90. When these inverter circuits are generically referred to, "81" is used as the reference numeral.

Details of the two inverter circuits 81L and 81R will be described later with reference to FIG. 22.

In FIG. 19, reference numeral 95 denotes a voice synthesizer that synthesizes electronically created voice, and the speaker 95S notifies the user of operations and notification when an abnormality occurs each time.

It is arranged in and receives an infrared signal from the top plate 15 direction. That is, this makes it possible to measure the temperature of the bottom surface of the pot or futaipan that is the object to be heated.

Of the temperature sensors TS3 to TS9, two temperature sensors TS4 and TS6 use a thermistor as a contact type sensor, and as shown in FIG. 13, the central portion of each of the IH coils 17L and 17R. It is placed in a cavity. These temperature sensors TS4 and TS6 are in direct contact with the lower surface of the top plate 15, or are in contact with the lower surface of the top plate 15 via a heat conductive inclusion. This makes it possible to measure the temperature of the top plate 15.

One of the temperature sensors TS3 to TS9, the temperature sensor TS7 (see FIG. 13), uses a thermistor as a contact type sensor and is installed on the upper surface of the holder 42. Then, the atmospheric temperature of the integrated display unit 30 and the input operation unit 40 is detected. Further, the two temperature sensors TS8 and TS9 use a thermistor and are attached to the upper surface of the heat sink 82 described later.

The lower unit 200 is also provided with at least two temperature sensors TS1 and TS2 in order to detect the internal space temperature of the lower unit 200, but the details will be described later.

Reference numeral 62 denotes a cooling fan drive circuit, which controls the drive power of the drive motors 60M and 61M of the first cooling fan 60 and the second cooling fan 61.

The display unit drive circuit 63 is mounted on the upper surface of the operation board 41 (see FIG. 18).

Reference numeral 84 denotes a vibration sensing device that detects shaking when an earthquake occurs. When a predetermined seismic intensity (acceleration) or higher is detected, a vibration sensing signal is sent to the integrated control device MC, and the integrated control device MC receives the signal. It is judged that an earthquake has occurred, and the power supply of all the heating means in use is shut off instantly.

This void is a closed space so that air does not flow to the outside. The peripheral edge of the lower heat shield plate 168 is fixed to the bottom wall surface of the heating chamber 113 in close contact with the lower end edge of the right side partition plate 166R and the left side partition plate 166L.

Reference numeral 169 is an upper case that is overlapped with the peripheral portion of the upper heat shield plate 167 so as to cover the entire upper portion of the upper heat shield plate 167. Reference numeral 170 is a lower case that is overlapped with the peripheral portion of the lower heat shield plate 168 so as to cover the entire lower portion of the lower heat shield plate 168.

As shown in FIG. 9, the upper case 169 and the lower case 170 have a vertically symmetrical shape and are made of a thin metal plate or heat-resistant plastic. The GP8 is a gap formed between the upper case 169 and the upper heat shield plate 167, and has a size of about several mm to 10 mm. The gap GP8 is a closed space so as not to allow air to flow to the outside.

The GP9 is a gap formed between the lower case 170 and the lower heat shield plate 168, and has a size of about several mm to 10 mm. This gap GP9 is a closed space so as not to allow air to flow to the outside.

A sheet or plate-shaped heat insulating material 175A (not shown) is arranged in the gap GP6. Similarly, a sheet or plate-shaped heat insulating material 175B (not shown) is arranged in the gap GP8.

A sheet or plate-shaped heat insulating material 175C (not shown) is arranged in the gap GP7. Similarly, a sheet or plate-shaped heat insulating material 175D (not shown) is arranged in the GP9. If each of these heat insulating materials 175A to 175D has a form in which a plurality of layers are stacked instead of a one-layer structure, the heat insulating performance is further improved. The planar size (vertical and horizontal dimensions) of each of the heat insulating materials 175A to 17D is at least larger than the respective installation ranges of the upper heater 163 and the lower heater 163B.

In FIG. 9, reference numeral 171 is a partition plate in which a passage 172 through which the cooling air RF5 flows is partitioned above the upper case 169. A communication port 173 is opened in the upper part of the rear wall surface of the partition plate 171, and the inlet end of the exhaust duct 102 is connected to the communication port 173.
Reference numeral 174 is a communication port formed at the rear portion of the ceiling surface of the heating chamber 113, and the entrance portion of the exhaust duct 102 is connected to the communication port 174. 102E is a terminal portion that is the final outlet of the cooling air.

As shown in FIG. 10, the exhaust duct 102 includes two independent internal passages 102A and 102B at the top and bottom, and the inverter circuit board 121 is cooled in the internal passage 102A on the upper side thereof. After that, the cooling air RF5 flows.
Further, in the other internal passage 102B, the cooling air RF6 introduced into the heating chamber 113 and having an increased temperature flows.

The wind speed of the cooling air RF5 is increased by the discharge port of the cooling air RF5 in which the opening area of the air passage is narrowed. Therefore, the cooling air RF6 is attracted by the cooling air RF5 in the vicinity of the discharge port. By such an action, the gas inside the heating chamber 113 is sucked into the internal passage 102B.
As a result, the two cooling air RF5 and RF6 are both efficiently discharged from the exhaust port 20 to the outside of the cooking cooker 1. It should be noted that instead of adopting such an attraction structure, a method of merging at the upstream stage before entering the exhaust duct 102 may be adopted.

In FIG. 10, 180 is a large feeding port formed on the back wall (rear wall surface) 113B of the heating chamber 113, and 181 is a cover that closes the feeding port 180 from the outside, and is a heat-resistant plastic that transmits microwaves. It is formed in the shape of a plate from heat-resistant glass. The cover 181 is fixed to the outside of the back wall (rear wall surface) 113B.

The cover 181 is in close contact with the back wall (rear wall surface) 113B. The antenna case 124 is fixed to the back wall 113B of the heating chamber 113 so as to cover the entire back side of the cover 181. The cover 181 is inserted inside the front opening of the antenna case 124 as shown in FIG.

Reference numeral 123 denotes a waveguide connected to the back surface side of the cover 181. The antenna driving motor 126 is thus fixed to the back surface side of the waveguide 123 via a heat-resistant sealing material 184.

The 126A is a rotation shaft of the antenna driving motor 126, and is installed horizontally in the front-rear direction. The antenna 125 is fixed to the free end side (front end portion) of the rotating shaft 126A. Although the rotating shaft 126A is made of plastic or ceramic material, only a certain range from the antenna 125 side is made of metal, and from there to the antenna driving motor 126 is heat-resistant and insulated from plastic, ceramic, etc. It may be formed of a material rich in properties.

Reference numeral 185 is a radio wave sealing chamber formed in a predetermined size around the rotation shaft 126A. This radio wave sealing chamber has a so-called choke chamber structure. Further, in order to prevent microwave leakage more effectively, a radio wave absorber (not shown) is arranged closer to the antenna driving motor 126 than the choke structure, and microwaves from the periphery of the rotating shaft 126A are arranged. You may try to prevent leakage. As for the choke structure in the microwave heating device, Japanese patent documents include, for example, Japanese Patent Application Laid-Open No. 2011-174669, Japanese Patent Application Laid-Open No. 2010-255978, and Japanese Patent Application Laid-Open No. 63-172828 (a quarter wavelength choke). Since there is a combination of a room and a radio wave absorber), detailed explanation will be omitted.

In FIG. 10, LA shows the dimensions from the back wall (rear wall surface) 113B of the heating chamber 113 to the tail end of the antenna driving motor 126. Hereinafter, this dimension is referred to as "protruding dimension". It is desirable to reduce this protruding dimension LA, but in reality, as described above, the dimensions of the antenna case 124 and the radio wave sealing chamber 185 are also required, and even if the external dimensions of the antenna driving motor 126 are reduced, there is a limit. There is. This dimension LA is 70 mm.

In FIG. 10, GP10 is a gap between the back surface of the antenna drive motor 126 and the inclined portion 101C of the lower case 101, 69 mm at the upper end of the motor 126, and conversely, the gap between the lower end and the lower case 101C is 53 mm. Degree. Since it is dimensionally impossible to arrange the case C154 in the gap GP10, in the first embodiment, the case C154 is displaced to the right from directly behind (behind) the antenna drive motor 126. It is arranged.
This makes it possible to incorporate the microwave heating device 120 in a narrow space behind the heating chamber 113.

Next, the internal structure of the door 114 will be described.
In FIG. 10, reference numeral 190 denotes a metal or plastic frame constituting the outer shell of the door 114, which is formed in a frame shape when viewed from the front side. Reference numeral 192 is an inner frame, which is made of a metal plate. An opening serving as a viewing window 192W is formed in the central portion of the inner frame 192.

Reference numeral 191 is a cover in which an outer peripheral edge portion is fixed between the inner frame 192 and the frame 190 so as to cover the entire front side of the inner frame 192, and is transparent and heat resistant so that the heating chamber 113 can be seen. It is made of plastic or glass.

Reference numeral 193 is an inner seal frame having innumerable small holes having dimensions that do not allow microwaves to pass through the portion corresponding to the viewing window 192W. The inner seal frame is formed by press-molding a thin metal plate as a whole, and a choke chamber 194 having an inlet (slit) formed on the heating chamber 113 side is formed on the outer peripheral edge portion.

Reference numeral 195 is a sealing plate made of a thin metal plate. As shown in FIG. 10, the outer peripheral edge portion of the seal plate 195 is bent in a series toward the inner seal frame 193 side. The choke chamber 194 forms the choke chamber 194 in a space surrounded by the outer peripheral edge portion of the seal plate 195 and the inner seal frame 193.

When the door 114 is completely closed, both the outer peripheral edge portion of the seal plate 195 and the inner seal frame 193 are in contact with the surface of the front plate 101F of the lower case 101. Therefore, the microwave supplied to the inside of the heating chamber 113 does not leak from the door 114 and the opening 113A on the front surface of the heating chamber 113.

Reference numeral 196 is a transparent sealing plate provided inside the portion of the inner frame 192 corresponding to the viewing window 192W, and is made of heat-resistant glass. Reference numeral 197 is a metal upper shielding plate having a width dimension equal to at least the width of the door 114 along the upper surface of the door 114. The upper shielding plate 197 is provided in an eaves shape close to the upper surface of the door 114, and is fixed to the lower case 101 with a fixing tool such as a metal screw so as to be electrically connected to the lower case 101.

Since the lower portion of the door 114 is supported by a hinge portion (not shown) in the lower case 101, the door 114 can be opened by holding the handle portion 115 and pulling it toward you.
At the initial stage of such opening, there is a concern that a gap is momentarily generated in the overlapping portion between the door 114 and the lower case 101 and a part of the microwave leaks. However, in the first embodiment, the upper shielding plate 197 is used. Thereby, such unwanted microwave leakage can be suppressed above the door 114.

In FIG. 12, reference numeral 201 denotes an introduction port formed in the front portion of the right side wall surface of the heating chamber 113, which is formed of a large number of holes having a small diameter so as not to leak microwaves. The reason why the introduction port 201 is provided in the front portion of the right side wall surface of the heating chamber 113 is to supply a part of the cooling air RF6 to the vicinity of the inside of the door 114 and suppress fogging of the viewing window 192W of the door 114. be.
The cooling air RF6 after cooling the heat radiating portion 122H of the magnetron 122 is guided to the introduction port 201 by the gap GP5R.

The temperature sensor 160 is located upstream of the introduction port 201 in the flow of the cooling air RF6, and a part of the cooling air RF6 is blown into the heating chamber 113 at the portion of the temperature sensor 160. The amount of cooling air RF6 reaching the introduction port 201 is small. However, the purpose of injecting air from the introduction port 201 is to "suppress fogging" of the seal plate 196 inside the door 114, and there is no problem with a small air volume. It is not necessary to adopt the supply of air from the narrow gap around the temperature sensor 160.

Next, the details of the various control means in the lower unit 200 will be described with reference to the block diagram shown in FIG. 19 again.
The microwave heating control unit 130 controls the electric power supplied to the inverter circuit 121A of the inverter circuit board 121, the magnetron 122, the antenna driving motor 126, and the two cooling fans 128 and 129, and starts their operation. , Stops, operating conditions, etc. are controlled.

The power supply circuit of the microwave heating control unit 130 is prepared separately from the power supply circuit 91 mounted on the power supply circuit board 55, and is a dedicated circuit of the microwave heating device 120. The power may be supplied from the power supply circuit 91.
The power supply circuit of the microwave heating control unit 130 is mounted on the power supply circuit board 127. Various electric components (diodes and the like) that convert AC power to DC are mounted on the power circuit board 127, and are housed in a case C154 in a sealed state (see FIG. 7).

When the microwave heating control unit 130 receives the command signal from the power control unit 72, the microwave heating control unit 130 operates so as to reduce the total power consumption of the microwave heating device 120 in response to the command signal, and outputs the magnetron 122. There is a function of transmitting a command signal such as lowering to the inverter circuit 121A.

The microwave heating control unit 130 includes a temperature sensor TS1 that detects the temperature of the heat radiation unit 122H of the magnetron 122. If the temperature of the heat radiating unit 122H of the magnetron 122 is higher than the specified value even after microwave heating is completed, the command signal for continuing the operation of the fourth cooling fan 129 until the temperature drops is sent to the fourth cooling. Send to fan 129.

Reference numeral 139 is a closing detection unit for the door 114. The closure detection unit 139 detects the open / closed state of any one or more of the latch switch 132A, the second door switch 132B, and the monitor switch 133 by the current flowing through each circuit or the open / close signal.

Since the circuit board constituting the closure detection unit 139 is attached to the support plate 137, whether or not the circuit board can be operated normally by removing the support plate 137 for inspection or measuring with the support plate 137 installed. Can be inspected (see Fig. 7).

Reference numeral 158 is a non-contact temperature measuring unit (infrared temperature measuring unit) that detects the temperature of food, cooking utensils, etc. placed in the heating chamber 113, and receives the temperature sensor 160 and the measurement signal from the temperature sensor. It consists of a circuit (not shown) that analyzes and converts it into temperature information.

The heating chamber control unit 159 controls the electric power supplied to the upper heater 163A and the lower heater 163B, and controls the start and stop of their operation, operating conditions (heat power, that is, calorific value) and the like. The control circuit of the heating chamber control unit 159 is mounted on a control circuit board (not shown).

When the heating chamber control unit 159 receives the command signal from the power control unit 72, the heating chamber control unit 159 operates so as to reduce the total power consumption of the upper heater 163A and the lower heater 163B in response to the command signal, and the upper heater 163A. And there is a function to transmit a command signal that lowers the output of the lower heater 163. In addition, in order to reduce the outputs of the upper heater 163A and the lower heater 163, the energization rate per unit time is changed to change the substantial thermal power.

Next, a configuration example of the drive circuit of the IH coils 17L and 17R of the cooking cooker 1 will be described. In the description of FIG. 22, an example of a circuit showing only one IH coil 17R will be described.

In the heating cooker 1, the induction heating operation is performed by supplying high frequency power to the IH coils 17L and 17R by the drive circuit 74.
The drive circuit 74 is provided for each IH coil. FIG. 22 is a diagram showing a configuration example of the drive circuit 74 of the IH coil 17R. Even with the IH coil 17L on the left side, the drive circuit may be the same or different.

As shown in FIG. 22, the drive circuit 74 includes a DC power supply circuit 75, an inverter circuit 81R, a resonance capacitor 76, an input current detection unit 77a, and an output current detection unit 77b.
The current detection data of the input current detection unit 77a and the output current detection unit 77b are sent to the IH control device 90.

The input current detection unit 77a detects the current input from the AC power supply 99 to the DC power supply circuit 22, that is, the current input to the drive circuit 74, and outputs a voltage signal indicating the detected value, that is, the input current value to the IH control device 90. Output to. 99 is a commercial AC power supply.

The DC power supply circuit 75 includes a diode bridge 78a, a reactor 78b, and a smoothing capacitor 78c, converts an AC voltage input from the AC power supply 99 into a DC voltage, and outputs the AC voltage to the inverter circuit 81R.

The inverter circuit 81R is a so-called half-bridge type inverter in which IGBTs 79a and 79b as switching elements are connected in series with the output of the DC power supply circuit 75. In the inverter circuit 81R, diodes 79c and 79d are connected in parallel with the IGBTs 79a and 79b as flywheel diodes, respectively.
The inverter 81R converts the DC power output from the DC power supply circuit 75 into high-frequency AC power of about 20 kHz to 80 kHz, so-called high-frequency power, and supplies the DC power to the resonance circuit including the IH coil 17R and the resonance capacitor 76.

The resonance circuit including the resonance capacitor 76 has a resonance frequency corresponding to the inductance of the IH coil 17R, the capacitance of the resonance capacitor 76, and the like.

With this configuration, a high-frequency current of about several tens of A flows through the IH coil 17R, and the high-frequency magnetic flux generated by the flowing high-frequency current induces the heated object N on the top plate 15 directly above the IH coil 17R. It is heated.

The IGBTs 79a and 79b are composed of, for example, a silicon-based semiconductor, but may be configured using a wide bandgap semiconductor such as silicon carbide or a gallium nitride-based material.

By using a wide bandgap semiconductor for the IGBTs 79a and 79b as the switching element, it is possible to reduce the energization loss of the IGBTs 79a and 79b as the switching element. Further, even if the switching frequency, that is, the drive frequency is set to a high frequency, that is, the switching is performed at high speed, the heat dissipation is good. Therefore, the heat radiation fins of the heat sink 82 to which the switching elements (IGBTs) 79a and 79b are attached can be miniaturized, and the drive unit can be miniaturized and the cost can be reduced.

The output current detection unit 77b is connected to a resonance circuit including an IH coil 17R and a resonance capacitor 76. The output current detection unit 77b detects, for example, the current flowing through the IH coil 17R, that is, the current output from the drive circuit 74, and outputs a voltage signal corresponding to the detected value to the IH control device 90. In this configuration, the half-bridge type inverter has been described, but the circuit for driving the IH coil 17R may be a full-bridge type inverter. Further, although the circuit described with reference to FIG. 22 is a current resonance type, a voltage resonance type may be adopted.

As described in FIG. 13, the wireless communication unit 49 communicates wirelessly with a home control device (not shown) that comprehensively manages the power consumption and operation information of home appliances in the home. It is a wireless communication means of the above, and can transmit and receive wireless signals. The home control device can also be connected to a portable information terminal such as a smart phone, a tablet-type terminal device, or the like via a public wireless communication network such as the Internet. As an example of the home control device, there is a power management device called a HEMS controller. In the first embodiment, as described with reference to FIGS. 14 and 15, the input key 43KP of the central operation unit 40M is pressed to switch the integrated control device MC to the “functional mode”, and the “HEMS registration setting” is the integrated display screen. There is a function that can be executed while looking at 30.

The wireless communication unit 49 is connected to the integrated control device MC by wiring, but the longer the wiring is, the more easily it is affected by noise. Therefore, the wireless communication unit 49 and the integrated control device MC are arranged close to each other, and the wireless communication unit is arranged. It is desirable to shorten the wiring connecting the 49 and the integrated control device MC.

Considering the influence of the above-mentioned noise, in the first embodiment, the wireless communication unit 49 is installed at the right end of the input operation unit 40. Specifically, the wireless communication unit 49 is installed at the right end of the operation board 41. Further, the integrated control device MC is installed in the left and right center portions of the input operation unit 40 (see FIG. 14).

The wireless communication unit 49 has an antenna unit that transmits, receives, or transmits / receives a wireless signal inside, and in order to make it easier to transmit / receive the wireless signal, the antenna unit of the wireless communication unit 49 is directly below the top plate 15. It is desirable to arrange them so that they are.

(Control menu of the central operation unit)
Next, a control menu displayed on the integrated display unit 30 by the central operation unit 40M and selectable will be described with reference to FIG. 23.

As described above, the "control menu" that can be selected between the left operation unit 40L and the right operation unit 40R is, for example, boiling water, boiling food, fried food (automatic cooking), etc., as shown in FIG. 25.
However, as shown in FIG. 23, there are 11 types of control menus that can be selected by the central operation unit 40M. These 11 types of control menus may be collectively referred to as a "control menu group" of the central operation unit 40M.

The control menu selectable by the central control unit 40M uses one or both of the microwave heating source 189 and the oven heating source 188. Therefore, it is basically different from the control menu of induction heating in which foodstuffs are indirectly heated via an object to be heated such as a pot.

The "control menu" that can be selected by the central operation unit 40M is different from the name of the final cooking or the name of the foodstuff obtained by heating with the microwave heating source 189 or the oven heating source 188. For example, "hamburger" and "tempura" are the names of cooked foods, not the "control menu" here.
The "control menu" can be said to be broadly classified in consideration of the type, method, conditions, etc. of heating until the cooking is completed, so the name of the control menu is, for example, "warm" or "oven (cooking)". It is conceptual and comprehensive.

The control menu that can be selected by the central operation unit 40M with reference to FIG. 23 will be described in detail below.
The “left display area” in FIG. 23 means the first area (display area) 30L of the integrated display unit 30. The "center display area" also means the second area 30M, and the "right display area" also means the third area 30R.

When the input key 43MC of the central operation unit 40M is operated, the control menu "warm" in the left display area of FIG. 23 is always displayed first in the first area 30L of the integrated display unit 30. This is because the control menu "warm" is set by default.

As is clear from the "left display area" in FIG. 23, in addition to "warming", a total of 11 controls such as "microwave oven manual", "leaf vegetable boiled", "RG cooking", "grill", and "oven" There is a menu. However, the "center heater" described at the bottom of the "left display area" in FIG. 23 is not actually displayed because it is not supported by the upper unit 100. This "central heater" corresponds to the case where another induction heating unit is added between the right heating unit 17HR and the left heating unit 17HL in the upper unit 100. Further, "RG" is an abbreviation for a range grill.

The content described in the "center display area" of FIG. 23 indicates the content displayed in the second area (display area) 30M of the integrated display unit 30. The contents of the default settings of the "center display area" are listed in the right column of the "center display area".

The content described in the "right display area" of FIG. 23 indicates the content displayed in the third area (display area) 30R of the integrated display unit 30. The contents of the default settings of the "right display area" are listed in the right column of the "right display area". The blank area means that nothing is displayed.

The control menu database is created according to the above rules.
Therefore, when the input key 43MC of the central operation unit 40M is operated, the first area 30L of the integrated display unit 30 is "warm", the second area 30M is "80 ° C", and the third area 30R. Is supposed to display no control conditions. Therefore, in this embodiment, information that can be used as a reference for cooking (hereinafter referred to as "guidance information 30P") is displayed in the third area 30R. This will be described later with reference to FIG. 35 and the like.

When the user displays one "control menu" from the "control menu group" of the central operation unit 40M in the central part of the first area, the control conditions (temperature, thermal power, time, etc.) corresponding to this control menu are set. , Is displayed simultaneously in the second area 30M and the third area 30R. After that, when the input key 43MS instructing the start of the heating operation is operated by the user, the heating operation by the microwave heating source 189 or the oven heating source 188 is started.

Detailed data such as specific contents, control conditions, and additional information of the control menu shown in FIG. 23, a display program, and the like are stored in the storage unit of the integrated control device MC.
The main control menus will be described below.

(1) Warming: It means heating food using a microwave heating source 189. This "warming" is also suitable for reheating food. Since the default setting is "80 ° C", microwave irradiation is automatically stopped when the food is heated to 80 ° C. In addition, "80 ° C." is a target temperature, and this temperature can be adjusted by the user before the start of heating. As shown in FIG. 23, it can be set in 5 ° C increments in the range of 0 ° C to 90 ° C. For heating frozen products, it can be set in 2 ° C increments in the range of -10 to 0 ° C. The microwave heating output is fixed at 500 W.

(2) Manual microwave oven: Heating food using a microwave heating source 189, which is performed by setting a heating time. The microwave heating output can also be selected from three stages of 500W, 200W, and 100W. The default heating time is 1 minute, but it can be set from 10 seconds to 15 minutes at 500 W output.

(3) Boiled leafy vegetables: Suitable for boiling foods, especially leafy vegetables such as spinach and Chinese cabbage, using a microwave heating source 189. The microwave heating output value is not displayed, and "standard" is displayed as the default display in the second area. The non-contact temperature measuring unit (infrared temperature measuring unit) 158 measures the temperature rise and automatically stops heating.

(4) Boiled root vegetables: It is suitable for boiling foods, especially root vegetables such as potatoes that eat roots and rhizomes, using a microwave heating source 189. The microwave heating output value is not displayed, and "standard" is displayed as the default display in the second area. Since the heating power value is determined in advance on the cooking device 1 side, when adjusting the heating power, change the default display "standard" in the second area to "weak" or "strong" ( Must be selected).

(5) Meat thawing: This is a control menu suitable for thawing various frozen meats.
(6) RG cooking: It is suitable for cooking using the heating chamber 113, and is cooked by combining microwave heating and oven heating. It should be noted that microwave heating is performed first, the food is heated to some extent, and then the pattern of heating with the upper heater 163A and the lower heater 163B, the pattern of heating in the reverse order, and the microwave heating and the heater heating are performed at the same time. There are three types of patterns. The heating power value (watt) at the time of microwave heating is not displayed, and the user can select one of "weak", "strong", etc. by looking at the display of the second area 30M and select the heating intensity. ..

(7) RG re-cooking: Suitable for reheating cooked food using the heating chamber 113.
(8) RG manual: Suitable for cooking using the heating chamber 113, and is for cooking by combining microwave heating and oven heating. It should be noted that microwave heating is performed first, the food is heated to some extent, and then the pattern of heating with the upper heater 163A and the lower heater 163B, the pattern of heating in the reverse order, and the microwave heating and the heater heating are performed at the same time. There are three types of patterns.

(9) Grill: The heating chamber 113 is used to heat food, and one or both of the upper heater 163A and the lower heater 163B are used as the heating source. As described above, the temperature of the heating chamber 113 is not controlled, and the control of detecting the temperature rise of the food and stopping the heating operation is not performed. The heating power of the upper heater 163A and the lower heater 163B is determined in advance by the heating chamber control unit 159 on the heating cooker 1 side. Grilled fish is a typical applicable cooking. Incidentally, the rated thermal power of the upper heater 163A is 1000 W, and the rated thermal power of the lower heater 163B is also 1000 W.
(10) Oven: Food is heated using the heating chamber 113, and one or both of the upper heater 163A and the lower heater 163B are used as the heating source. The temperature of the heating chamber 113 is measured by the temperature measuring unit 158, and the energization control is performed by the heating chamber control unit 159 so as to reach the set target temperature. As shown in FIG. 23, the default temperature is 180 ° C., so the user can change this target temperature if desired. As described in the section of "grill", the rated thermal power of the upper heater 163A is 1000 W, and the rated thermal power of the lower heater 163B is also 1000 W. Then, the energization rate for the upper heater 163A and the lower heater 163B is controlled by the heating chamber control unit 159, and the calorific value of these two heaters 163A and 163B is controlled.

(Operation of cooking cooker)
Next, an outline of the operation of the cooking cooker 1 having the above configuration will be described with reference to FIGS. 24 to 30.

FIG. 24 is a flowchart for explaining the entire control operation of the cooking device 1 before the start of cooking.
FIG. 25 is a flowchart for explaining a control operation at the time of induction cooking in the cooking device 1.

FIG. 26 is a flowchart for explaining a control operation in the case of performing microwave heating during induction cooking in the cooking device 1. FIG. 27 is a flowchart for explaining the control operation of the cooking device 1 of FIG. FIG. 28 is a flowchart for explaining the control operation of the cooking device 1. FIG. 29 is a flowchart for explaining the control operation of the cooking device 1. FIG. 30 is a list showing the correspondence between the cooling fan of the cooking device 1 and the type of cooking.

FIG. 24 will be described.
The basic operation program from turning on the power to starting cooking preparation is stored in the storage device MM inside the integrated control device MC.
In the built-in type cooker 1, the power plug 106A is always connected to the commercial (alternating current) power supply 99 from the time when the kitchen furniture 2 is installed, so that the user can use the operation button 98 of the main power switch 97 (see FIG. 19). ) To turn on the power (step ST1 in FIG. 24).

Then, a predetermined low power supply voltage is supplied to the integrated control device MC via the DC power supply conversion unit 92 in the power supply circuit board 55, and the integrated control device MC is started. The integrated control device MC itself starts diagnosing the presence or absence of an abnormality by its own control program.

Then, the presence or absence of abnormalities in the IH control device 90, the heating chamber control unit 159, and the microwave heating control unit 130 that centrally control the induction heating source 9 is checked.

A total of seven temperature sensors TS3 to TS9 are connected to the temperature detection circuit 93 of the upper unit 100 in order to detect the temperature of the top plate 15, the inverter circuits 81L, 81R, the vicinity of the integrated display unit 30, and the like. Therefore, the detection temperature of those temperature sensors is transmitted to the temperature detection circuit 93. As a result, the IH control device 90 can determine the presence or absence of an abnormality (ST2).

Further, the heating chamber control unit 159 and the microwave heating control unit 130 can also acquire the detected temperatures from the temperature sensors TS1 and TS2 and determine the presence or absence of an abnormality.

In step ST2, there is "transmission of activation information to the outside", which is called "integrated information management device" or "integrated power control device" (HEMS controller) in a living space such as a kitchen from the wireless communication unit 49. It means giving a notice to the "home control device" (not shown) of the start of operation of the cooking cooker 1. This will be explained later.

Since the temperature information of the main component built in the upper unit 100 is collected in the IH control device 90, the IH control device 90 performs an abnormal heating determination process as an abnormality monitoring control before the start of cooking. For example, when the temperature detected by the temperature sensor TS7 is higher than the heat resistant temperature (for example, 70 ° C.) of an electronic element such as the liquid crystal display screen 30D in the integrated display unit 30, the IH control device 90 determines that the temperature is abnormally high. Then, the integrated control device MC is notified of the abnormality, and processing such as displaying or notifying that the operation cannot be started is executed.

If no abnormality is found, the IH controller 90 signals the integrated controller MC. Then, the integrated display unit 30 is activated and displays that "cooking can be started because there is no abnormality" (ST3). The display screen at this initial time point will be described later with reference to FIG. 32.
At the same time, the voice synthesizer 95 notifies the content similar to the content displayed by the integrated display unit 30 by voice (ST3).

In step ST3, the wireless communication unit 49 accesses the "home control device" and acquires information such as cooking menus and recipe information useful for health management within a range set in advance by the user. For example, the information previously transmitted by the user of the cooking cooker 1 to the "home control device" via the Internet line using a portable information terminal device or the like can also be acquired when the integrated display unit 30 is started. .. When some information is acquired, a dedicated caution information lamp (not shown) provided near the input operation unit 40 of the upper unit 100 is turned on to notify the user.

Next, after the abnormality determination is completed as described above, the integrated control device MC performs notification and voice guidance for prompting the selection of the heating means by the integrated display unit 30 and the voice synthesizer 95 (ST4).

Then, the IH control device 90 determines whether or not the heating source of the lower unit 200 has been selected from the operation information of the central operation unit 40M in the input operation unit 40 (ST5).

If the selection is not made within a certain grace time (for example, 30 seconds), or immediately after step ST4, the user operates at least one of the left operation unit 40L and the right operation unit 40R. In this case, it is determined that only the heating source of the upper unit ST6, that is, the IH coils 17L and 17R is selected (“Yes” in step ST6).

If step ST6 is "Yes" as described above, the process proceeds to the next step ST10. Subsequent control steps for induction heating will be described later with reference to FIG. 25.

On the other hand, when the heating source of the lower unit 200 is selected in step ST5, the integrated control device MC proceeds to the menu selection step ST8 of the two heating sources included in the lower unit 200. Note that this step ST5 is a case where the central operation unit 40M is operated.

In step ST8, as shown in FIG. 24, four menus are displayed in a list state on the integrated display unit 30. Or they are displayed in order.

The menu displayed at the stage of step ST8 in FIG. 18 is based on the heating source of the lower unit 200, and the following four menu selection units are displayed.
(1) A cooking menu (ST9A) using at least one of the upper heater 163A and the lower heater 163B. The "grill" and "oven" of the control menu shown in FIG. 23 correspond to this.
(2) A cooking menu (ST9B) in which a microwave heating device 120 is used in combination with the above (1). This corresponds to "RG cooking" in the control menu shown in FIG. 23.
(3) Cooking menu (ST9C) using the microwave heating device 120. This corresponds to "microwave oven manual", "leaf vegetable boiled" and the like in the control menu shown in FIG. 23.
(4) Cooking used by combining at least one of the upper heater 163A and the lower heater 163B, at least one of the microwave heating devices 120, and an induction heating source (IH coil 17L, 17R) of the upper unit 100. Menu (hereinafter referred to as "cooperative cooking menu") (ST9D). This is not included in the control menu shown in the first area 30L of FIG. 23.

The route from the stage of step ST10 to step ST9D is shown by a broken line, but it is better to perform cooperative cooking from the middle after proceeding with the operation to select the heating source of the upper unit 100 in this way. If it is found that, the menu of the cooperative cooking may be selected without returning to the step ST5. Also, in the same way, it is possible to select cooperative cooking at another opportunity so that the cooperative cooking can proceed from the middle. This will be described in FIG. 25 below.

FIG. 25 shows the operation steps of the integrated control device MC after the step (ST11) in which the induction heating menu is selected.

Next, the control operation during induction heating will be described with reference to FIG. 25.
The following will be described with an example of using the right heating unit 17HR.
When the input key 43R1 on the right side is touched, the IH control device 90 determines that the user has commanded the heating preparation operation.

It is estimated whether or not the object to be heated (metal pot, frying pan, etc.) is placed above the IH coil 17R, or whether or not the bottom area of the object to be heated is larger than a predetermined value, and this estimation result is obtained. It is transmitted to the IH control device 90, and it is determined whether the heat treatment is suitable for a standard diameter pan or a large diameter pan (step MS1).
If the pot is compatible but has a large diameter, or if it is not compatible with heating, the treatment is different from that of the standard pot.

In response to a command from the IH control device 90, the integrated control device MC displays a display prompting the display screen 30D of the integrated display unit 30 to select a “control menu” for the desired cooking (MS2).

When the user selects and inputs the cooking "control menu", the heating power, the cooking time, etc. with the right operation unit 40R (MS3), the induction heating operation is started in the right heating unit 17HR in earnest (MS4).
The "control menu" displayed on the integrated display unit 30 includes "high-speed heating", "fried food", "boiler", "preheat", "rice cooking", "boil", "boil + heat retention", and "cooperative heating". There are eight. However, in order to simplify the operability, it may be set so that a part or all of the above eight control menus cannot be selected in the "function setting" described later.

When the user selects any one of these eight control menus, the control conditions corresponding to those control menus are automatically selected by the built-in program of the IH control device 90, and the energization amount of the IH coil 17R ( Thermal power), energization time, etc. are set. Depending on the cooking menu, a display prompting the user to set an arbitrary heating power, energizing time, etc. is displayed on the display unit (MS5).

Unless the user operates the key 43R1 to stop using the key within a certain period of time (for example, 15 seconds or 30 seconds) after the above display is performed, the IH control device 90 will perform induction heating after that time has elapsed. The inverter circuit 81R of the circuit 94R is driven and induction heating is started (MS6).

The case of the "large-diameter pan" is basically the same as in steps MS1 to MS7, but some of the eight control menus shown in FIG. 25 cannot be selected as the control menu. The "high-speed heating menu" can be heated only in the case of "normal pot" or "large-diameter pot" using the large-diameter IH coil 17L on the left side. The small pot means that the diameter of the bottom surface of the pot is less than 10 cm in the first embodiment, and it is detected as unsuitable for induction heating, and induction heating cannot be performed.

Next, the integrated power control operation when two or more different types of heating sources are used at the same time, such as induction heating and microwave heating, will be described with reference to FIGS. 26 to 28. It should be noted that the examples described with reference to FIGS. 26 to 28 are not the case of the above-mentioned "cooperative cooking".

The example shown in FIG. 26 is a case where the user tries to perform microwave heating using the heating chamber 113 of the lower unit 200 during the period in which the induction heating is first performed in the upper unit 100. Even when oven cooking, grill cooking, etc. are performed using both or one of the upper heater 163A and the lower heater 163B during the period of induction cooking, as described in FIG. 26. Basic total power control (in the entire cooking cooker 1) is performed by the integrated control device MC and the power control unit 72.

During the period of induction heating, when the user tries to perform microwave heating using the heating chamber 113 of the lower unit 200, first the central operation unit 40M of the input operation unit 40 is used to heat the lower unit 200. There is a way to select the heating source.
However, an easy way to do this is to open the door 114 as is. That is, in the first embodiment, when the upper unit 100 is operated (when the main power switch 97 is in the ON state), cooking by the lower unit 200 can be started as it is. Therefore. It is not necessary to turn on the main power switch 97 as in the upper unit 100.

When the door 114 is opened, as described in the main part of the door open / close detection mechanism 131, there are a latch switch 132A and a door switch 132B that are opened / closed according to the opening / closing of the door 114. Then, the integrated control device MC may monitor the opening of both or one of the latch switch 132A and the door switch 132B by an appropriate means (sensor, switch, or the like).

In FIG. 26, when the signal indicating that the door 114 of the heating chamber 113 is opened is received as described above, the integrated control device MC provides voice guidance to the user (step S2). The content of the voice guide is, for example, "press the start button to start heating".

In the default setting of microwave heating, the target temperature is 80 ° C., so even if the door 114 is closed and heating is started as it is, it automatically stops when it is detected that the temperature of the object to be cooked reaches 80 ° C. When changing the temperature to 80 ° C. (for example, 75 ° C.), the input key 43MS (see FIG. 15) may be pressed after changing the temperature conditions.

When the user gives an instruction to "start heating" with the input key 43MS of the central operation unit 40M, the consumption of the third cooling fan 128, the fourth cooling fan 129, etc. is added to the rated power consumption value determined by the magnetron 122. Using the power consumption value known in advance, reflecting the power, the integrated control device MC determines in step S3 whether or not the total power regulation value is exceeded.

For example, since the integrated control device MC has the thermal power value of the induction heating and the power consumption of the first cooling fan 60 and the second cooling fan 61 that have started earlier as data, the power consumption of the upper unit 100 And the total value of the power consumption of the microwave heating device 120 can be calculated. The integrated control device MC may acquire the power consumption data of the inverter circuit 81 at the stage when the central operation unit 40M is operated.

When step S3 is "Yes", it is necessary to reduce either the output of the operating IH coil 17R or the heating power of microwave heating. In step S3, the priority of the cooking of the induction heating at that time is determined from the control menu of the induction heating and the cooking step. For example, when rice is cooked in the upper unit 100 (particularly, the "boiling step"), the rice cooking (boiling step) is prioritized and the heating power of the heating source of the upper unit 100 is not reduced.

Further, when the upper unit 100 is performing "fried food", the fried food is automatically controlled to increase the heating power so that the temperature of the cooking oil does not drop excessively according to the input of foodstuffs and the like. Therefore, even in such a case, the thermal power of the heating source of the upper unit 100 is not reduced.

If it is determined in step S5 that the induced heating is prioritized, the power consumption of the microwave heating is reduced. Therefore, if the rated output of the microwave is 500 W (power consumption is 900 W), the power consumption is temporarily reduced. For example, the output is set to 300 W. Then, the user is notified that such a restriction is applied. The notification is performed by the integrated display unit 30 and the voice synthesizer 95 (S6).

Then, the integrated control device MC issues a command signal to the microwave heating control unit 130, and starts microwave heating with low thermal power (S7).
Since it has a non-contact temperature measuring unit (infrared temperature measuring unit) 158 that detects the temperature of food, cooking utensils, etc. placed in the heating chamber 113, whether or not the food has been heated and reached the target temperature. Is monitored by the microwave heating control unit 130 (S8).

If the target temperature is not reached, it is determined whether or not the induction heating operation of the upper unit 100 is completed (S9). The above steps S8 and S9 are repeated until the target temperature is reached.

When the target temperature is reached, a signal is output from the microwave heating control unit 130 to the integrated control device MC. Then, the process proceeds to the next step S12, and the notification that the microwave heating is completed is notified.

When the induction heating is completed, the process proceeds to step S10, a command is issued to the microwave heating control unit 130, the heating power is initially restored to the set thermal power intended by the user, and the microwave heating is continued (S10). Then, the monitoring of the temperature of the object to be heated is continued (S11).

Then, when the target temperature is reached, the integrated control device MC receives a signal from the microwave heating control unit 130, proceeds to step S12, and notifies that the microwave heating is completed.

In the example shown in FIG. 26, the power priority between two parties, microwave cooking and induction heating, is the control menu (eg, “fried food”) and cooking process (eg, “fried food”) being performed in induction heating. , It was a premise to judge the priority with induction heating at that time from the "boiling process" of rice cooking.

Therefore, when the power priority between the microwave heating cooking and the induction heating cooking is always set to the microwave heating side, the instruction "heating start" is given to the input key of the central operation unit 40M. Before the 43MS, for example, a warning message is displayed on the integrated display unit 30, and a warning message is also output from the voice synthesizer 95. Further, even if microwave heating is started thereafter, the output value is not forcibly lowered as in the above example.

The power priority of the induction heating source 9, the oven heating source 188, and the microwave heating source 189 in the entire heating cooker 1 can be set in the "function setting" described later, and once. If set, even if the main power switch 97 is turned off, the setting conditions are stored in the integrated control device MC and are inherited after the next cooking.

In the example shown in FIG. 26, the temperature of the object to be heated was monitored, and when the target temperature was reached, the microwave heating was terminated. However, since there is also a control method in which the irradiation time of the microwave is measured and the cooking is terminated when the set time elapses, FIG. 27 will be described next.

FIG. 27 is an example in the case where a control method for terminating cooking by the irradiation time of microwaves is adopted.
Since the steps up to step S6 are the same as those in FIG. 26, the description thereof will be omitted.

When the microwave heating is started in step 7, the microwave heating control unit 130 calculates the correction (extension) of the heating time when the output of the magnetron 122 is lowered to a certain value. Then, in step S8, the time after the extension is determined as "set time 1" (S8), and steps 9 and 8 are repeated.

In the process, when the induction heating of the upper unit 100 is completed, the operation required time (set time 2) is recalculated in consideration of the elapsed time from the start of heating (step S7).

Then, when the set time 2 has elapsed, the microwave heating is terminated and this is notified (S12). Until the set time 2 elapses, the temperature monitoring by the non-contact temperature measuring unit (infrared temperature measuring unit) 158 may be used together.

Next, FIGS. 28 and 29 will be described.
28 and 29 are flowcharts for explaining the control operation of the cooking device 1. In the examples shown in FIGS. 28 and 29, the user attempts to perform microwave heating using the heating chamber 113 of the lower unit 200 during the period in which the induction heating is first performed in the upper unit 100. This is the case. Even in this case, the basic total power control (in the entire cooking cooker 1) as described with reference to FIG. 26 is performed by the integrated control device MC and the power control unit 72.

In FIGS. 28 and 29, unlike FIGS. 26 and 27, there is an integrated control device MC and an induction heating device including a microwave heating device 120, an IH coil 17L, 17R, an inverter circuit 81, and the like. It also shows the sending and receiving of signals.

In FIGS. 28 and 29, L1 to L10 indicate the generation timing of each operation signal, command signal, and the like. When the main power switch 97 is turned on in the upper unit 100, a start signal is transmitted to the integrated control device MC (L1).

After that, when the input operation unit 40 determines the thermal power of the IH coils 17L and 17R, the control menu, and the like (see steps MS2 and MS3 in FIG. 25), information indicating the contents is transmitted via the integrated control device MC (L2). .. That is, the IH control device 90 receives information indicating conditions such as the maximum thermal power and the operating time at the time of induction heating from the integrated control device MC. Then, if there is an induction heating start command from the input operation unit 40, the IH control device 90 starts the heating operation by the induction heating circuits 85L and 85R.

A case where the induction heating is started in this way and the microwave heating is also started will be described. It is assumed that the induction heating is started at the maximum thermal power of 3200 W of the left IH coil 17L.

When the user opens the door 114, as described with reference to FIG. 26, both the latch switch 132A and the door switch 132B are opened, and the sensor (not shown) monitoring the door 114 is used to open the door 114. A signal indicating the opening of the door is transmitted to the integrated controller MC (L3).

When the user inputs the thermal power in the central operation unit 40M, the integrated control device MC issues a command signal for starting operation to the microwave heating control unit 130. Then, the process proceeds to the next step S3.
Alternatively, when the user simply gives an instruction to "start heating" at the central operation unit 40M, the integrated control device MC issues a command signal for starting operation to the microwave heating control unit 130.

If there is no abnormality on the microwave heating control unit 130 side, a "notice signal" for starting cooking is transmitted from the microwave heating control unit 130 to the integrated control device MC (L4). For example, in the case of a microwave output of 500 W, when the rated power consumption of the entire microwave heating device is 1000 W, it becomes a "notice signal" including information using 1000 W as shown in FIG. 28.

Next, upon receiving information from the integrated control device MC, the power control unit 72 reflects the power consumption of the third cooling fan 128, the fourth cooling fan 129, etc. in advance in the rated power consumption value determined by the magnetron 122. Using the power consumption value known in, find the total power consumption when microwave heating and induced heating are performed at the same time, and determine whether this total value exceeds the total power regulation value. (Same as step S3 in FIGS. 26 and 27). Then, the result is transmitted to the integrated control device MC.

As another method, the upper limit of the total electric power of the induction heating source 189 and the oven heating source 188 of the lower unit 200 is determined (for example, 2000W), and the lower unit 200 and the upper unit 100 (induction heating source 9) are simultaneously used. When used, it may be determined whether or not the total power regulation value is exceeded.

When step S3 is "Yes", it is necessary to reduce either the output of the operating IH coil 17R or the heating power of microwave heating. In the next step S4, the integrated control device MC determines the cooking priority of the induction heating at that time from the control menu of the induction heating and the heating step.

In the example of FIG. 28, since the microwave heating is set to be prioritized, the thermal power of the microwave heating is not reduced.

When it is determined in step S5 that microwave heating is prioritized, in order to reduce the power consumption of induction heating, the microwave heating control unit 130 is instructed to control the target thermal power of the IH coil 17R to reduce the power consumption. Temporarily lower. Notify the user that such restrictions will be applied. The notification operation is performed by the integrated display unit 30 and the voice synthesizer 95.

Then, the microwave heating control unit 130 instructs the inverter circuit 81R to change the microwave heating to a low thermal power (L5).

When the power reduction process on the inverter circuit 81R side is completed, the microwave heating control unit 130 determines from the current values of the input current detection unit 77a and the output current detection unit 77b that the power has been reduced. Then, the fact that the power reduction is completed is transmitted to the integrated control device MC (L6). In response to this transmission, the integrated control device MC transmits a permission signal for starting the heating operation to the microwave heating device 120 (L7).

The inverter circuit 121A has a current detection unit (not shown) such as an input current detection unit 77a and an output current detection unit 77b used in the inverter circuit 81R of the upper unit 100.

Therefore, when the microwave heating is completed, the microwave heating control unit 130 determines from the current detection value of the inverter circuit 121A that the heating operation has been completed, and notifies the integrated control device MC of the heating operation with a specific signal ( L8). Further, the microwave heating may be performed only for a certain time depending on the timer setting, and in that case, the microwave heating control unit 130 detects the lapse of the time and notifies that the heating operation is completed (L8).

After the microwave heating is completed, the integrated control device MC issues a command signal to the microwave heating control unit 130 so as to return to the set thermal power initially desired by the user (L9). Then, the thermal power is raised to the initial target level and the induction heating is continued (S10).

Then, when the set cooking time or the target temperature is reached, the microwave heating control unit 130 ends the induction heating. Then, the integrated control device MC is notified that the operation has been completed (L10).

(Basic operation of induction cooking)
Next, in the cooking apparatus 1 according to the first embodiment, the basic operation of each part when induction heating is performed will be described.

When the input operation unit 40 is instructed to start the induction heating unit, the IH control device 90 issues a drive command to the induction heating circuits 85 and 85R corresponding to the designated heating unit, and the IH coils 17L and 17R. Drives the inverter circuits 81L and 81R of.

An operation command signal is output from the IH control device 90 to the cooling fan drive circuit 62.
The operation of the first cooling fan 60 and the second cooling fan 61 is started at the same time as or slightly delayed from the start of driving the inverter circuits 81L and 81R.

The ventilation capacities of the first cooling fan 60 and the second cooling fan 61 do not have to be fixed. For example, the blowing capacity may be automatically changed between the weak operation and the strong operation according to the temperature of the temperature sensor TS 8 of the heat sink 82 and the temperature sensor TS that detects the temperature in the vicinity of the integrated display unit 30.

Generally, if the cooling fan is changed from weak operation to strong operation, the wind noise of the fan becomes louder, which may cause noise. Therefore, the temperature detected by the two temperature sensors TS7 and TS8 and the operating strength of the cooling fans 60 and 61 are determined as a correspondence table (data table) from the data such as the preliminary ventilation test, and this correspondence table is determined. It is stored in the storage device 90R of the IH control device 90. Then, the IH control device 90 may change the operating conditions of the first cooling fan 60 and the second cooling fan 61 at any time according to the data table.

When the first cooling fan 60 is operated, air is sucked from the ventilation hole 64 located directly below the first cooling fan 60. The cooling air RF1 is pushed into the first air passage F1 from the air outlet 60A as shown by an arrow in FIG.

When the second cooling fan 60 is operated, air is sucked from the ventilation hole 64 located directly below the second cooling fan 60. The cooling air RF2 is pushed into the second air passage F2 from the air outlet 61A as shown by an arrow in FIG.

The ventilation holes 64 located directly below the first cooling fan 60 and the ventilation holes 64 located directly below the second cooling fan 60 are individually provided adjacent to each other on the bottom surface of the upper case 16, but a large number of them are provided. The small hole group may be provided and the small hole group may be shared.

A diode 79c (see FIG. 22) and other electrical components are mounted on the upper surface of the inverter circuit board 80, and they are cooled by the cooling air RF1.

Two IGBTs 79a and 79b are used for one IH coil 17L. These two IGBTs are collectively called a power control switching element 83.
Further, the power control switching element 83 is also used for the other IH coil 17L.

The two power control switching elements 83 generate heat during the induction heating operation, but are continuously cooled by the cooling air RF1.

The cooling air RF3 advances to the right while cooling parts such as various switches, a liquid crystal display screen, and a display unit drive circuit 63 that receive input operations arranged in the input operation unit 40.

Some of the cooling air RF1 changes its direction upward when it exits the outlet FO of the cover 70, but because of the momentum of the cooling air RF2 merging from the front side, the cooling air RF1 is above the cover 70 like the cooling air RF3. Is largely divided into those traveling in the direction of the filter circuit board 54 as shown in the cooling air RF4 and those traveling in the direction of the filter circuit board 54.

The cooling air RF3 flows below the IH coil 17R on the right side, and then flows directly below the IH coil 17L on the left side. In this process, the two IH coils 17R and 17L are cooled. Generally, the temperature of this type of IH coil rises to around 250 ° C to 300 ° C during the induction heating operation. Therefore, as described above, cooling is performed with the cooling air RF3, which is a combination of the two cooling air RF1 and RF2.

As described with reference to FIGS. 13 and 18, the exhaust window 52A exists in the range on the left side from the left and right center lines CL1 and has only the length indicated by the reference numeral LF. Therefore, after passing through the filter circuit board 54, the cooling air RF4 travels in the leftward direction, passes through the through hole 53A, and is discharged from the exhaust window 52A.

The cooling air RF3 that has cooled the IH coils 17L and 17R also travels in the direction of the exhaust window 52A, which is the final exhaust port, passes through the through hole 53A, and is discharged from the exhaust window 52A. As a result, the cooling air RF3 and RF4 flowing inside the upper case 16 reach the exhaust port 20. Then, it is discharged from the exhaust cover 19 into the room.

Since the exhaust window 52A is installed only at a position away from the filter circuit board 54, the cooking liquid or water overflowing from the pot or the like (hereinafter, these are referred to as “foreign matter”” is placed on the exhaust cover 19 during operation. ) Flows, it is possible to prevent the foreign matter from passing through the exhaust port 20 and reaching the filter circuit board 54. Therefore, it is possible to prevent the cause of electric leakage or failure. As described above, the filter circuit board 54 and the gap GP1 are separated by a partition plate 52 except for the exhaust window 52A. The term "separation" as used herein does not mean a separation that can completely block the flow of air, but a separation that can prevent the intrusion of foreign substances that have been added or flowed down from above.

(Basic operation of microwave cooking)
Next, in the cooking apparatus 1 according to the first embodiment, the basic operation of each part when microwave heating is performed will be described.

When the main power switch 97 is turned on, microwave cooking can be started as it is even if the upper unit 100 does not actually execute induction cooking. However, once the main power switch 97 is turned off, it is necessary to first turn on the main power switch 97 in order to start microwave cooking.

For safety reasons, the main power switch 97 automatically resets after a certain period of time (for example, 30 minutes) from the last timing when any of microwave heating, oven (heating chamber 113) heating, and induction heating is finished. Will be released. Alternatively, when the temperatures of the top plate 15 and the heating chamber 113 all drop below the specified value, the main power switch 97 is automatically opened. Such safety measures are adopted.

Next, the door 114 is opened, food or the like is put into the heating chamber 113, and after occupying the door 114, the input key 43MS (see FIG. 15) is used in the central operation unit 40M of the input operation unit 40. When the start of microwave cooking is commanded, the integrated control device MC issues a drive command to the microwave heating control unit 130 to start the operation of the third cooling fan 128 and the fourth cooling fan 129.

The microwave heating control unit 130 drives the inverter circuit 121A of the magnetron 122 to radiate microwaves from the oscillation unit 122A. The microwave referred to here is a radio wave of 2450 MH ± 50 MHz.

The generated microwave is guided from the waveguide 123 into the antenna case 124. Since the driving motor 126 of the antenna 125 starts operation at the timing when the microwave is oscillated, the microwave introduced in the antenna case 124 is caused by the action of the rotating antenna 125 and the rotating shaft 126A. It can be evenly propagated inside the heating chamber 113. Since the operation of this type of antenna and the rotating shaft 126A is described in detail by, for example, Japanese Patent No. 4836965 and Japanese Patent No. 5674914, detailed description thereof will be omitted.

When the third cooling fan 128 is operated, air is sucked into the case A150 from the intake port F152F formed in the bottom plate 101U of the lower case 101 to become the cooling air RF5. Then, the cooling air RF5 first cools the inverter circuit board 121, and cools various electric components mounted on the circuit board.

Next, the cooling air RF5 passes through the communication port B138B and the communication port A138A provided at two locations above and below the case A150, and the cooling air RF5 passing through the communication port B138B hits the back surface of the temperature sensor 160.

The temperature sensor 160 is installed in the mounting hole of the right partition plate 166A. There is a minute gap of several mm or less between the outer shell case of the temperature sensor 160 and the rim of the mounting hole. The cooling air RF5 passes through this gap and is blown out from the detection window 161 of the temperature sensor 160 into the heating chamber 113.

On the other hand, most of the cooling air RF5 that has cooled the inverter circuit board 121 is guided from the communication port A138A to the passage 172. That is, the guide is guided to the passage 172 formed between the upper case 169 covering the upper part of the heating chamber 113 and the partition plate 171. This passage has an effect of preventing the high heat from being transmitted to the upper unit 100 side even if the upper heater 163A above the heating chamber 113 has a high temperature exceeding 300 ° C.

Looking at the position of the communication port 173 from the communication port A138A in a plane, the communication port 173 is located diagonally rearward across the passage 172. That is, there is a communication port at the farthest position.
Therefore, the entire air in the passage 172 is guided to the communication port 173 and introduced into the exhaust duct 102 that passes through the communication port 173 and extends horizontally to the rear (see FIG. 10).

When the cooling air RF5 exits the exhaust duct 102, it merges with the cooling air RF6 rising from the lower side and is discharged into the room from the exhaust port 20.

Next, the flow of the cooling air RF6 by the fourth cooling fan 129 will be described.
When the fourth cooling fan 129 is operated, air is sucked into the inside of the case A151 from the intake port B152B formed in the bottom plate 101U of the lower case 101 as shown in FIG. 8, and becomes the cooling air RF6. Then, the cooling air RF6 first cools the heat radiating portion 122H of the magnetron 122, passes through the radiating portion 122H, and reaches the inside of the duct 153.

The cooling air RF6 then enters the void GP5R adjacent to the right side of the heating chamber 113 from the duct 153 and proceeds to the front side. Then, as shown in FIG. 12, it is introduced into the heating chamber 113 from the introduction port 201.

Since the introduction port 201 is located near the opening 113A of the heating chamber 113, a part of the cooling air RF6 also reaches the inside of the door 114 and eliminates the fogging generated on the heating chamber 113 side of the seal plate 196. ..

The cooling air RF6 introduced into the heating chamber 113 has the purpose of discharging water vapor, smoke, and the like generated from the object to be heated such as food inside the heating chamber 113. Specifically, the cooling air RF6 moves from the front part of the heating chamber 113 to the rear part as shown in FIG. 10, and finally reaches the communication port 174 formed in the ceiling part at the rear part.

The cooling air RF6 is introduced into an exhaust duct 102 extending horizontally rearward from the communication port 174. Then, when the cooling air RF6 exits the exhaust duct 102, it joins the cooling air RF5 so as to be attracted to the updraft, and is discharged from the exhaust port 20 into the room.

Even when the initial air volumes of the cooling air RF5 and the cooling air RF6 were the same, the wind speed was faster when the cooling air RF5 was discharged from the duct 102 due to the difference in the path as in the first embodiment. .. Therefore, it has an action of attracting the cooling air RF5 discharged from below.

Since the cooling air RF5 and RF6 are forcibly discharged from the exhaust duct 102, an exhaust fan may be provided in the middle of the exhaust duct 102. In the first embodiment, since such an exhaust fan is omitted, it can be realized at low cost, and it is advantageous in considering the arrangement of parts inside the upper unit 100.

(Basic operation of oven cooking)
Next, in the cooking apparatus 1 according to the first embodiment, the basic operation of the oven heating device 140 will be described.

When the main power switch 97 is turned on, the integrated control device MC presumes that some kind of cooking is started and pre-starts. Therefore, even if the upper unit 100 does not actually perform the induction cooking or the microwave cooking, the oven cooking can be started as it is. However, once the main power switch 97 is turned off, it is necessary to first turn on the main power switch 97 in order to start cooking in the oven.

Next, the door 114 is opened to put food or the like into the heating chamber 113, and then the central operation unit 40M of the input operation unit 40 selects a cooking control menu using the heating chamber 113. For example, in the case of cooking to bake fish or meat, the heating time and heating power are set. However, when the automatic baking control menu is selected, the heating power is automatically set by the heating chamber control unit 159. The selection of this control menu will be described later with reference to FIGS. 32 to 38.

The heating chamber control unit 159 receives a command signal from the integrated control device MC and controls whether or not the upper heater 163A and the lower heater 163B are energized, the energization time zone, the energization pattern (intermittent heating), the thermal power, and the like.

The temperature sensor TS2 detects the temperature inside the heating chamber 113 with an infrared signal, and transmits the detected temperature data to the heating chamber control unit 159. The heating chamber control unit 159 controls the energization of both the upper heater 163A and the lower heater 163B, or one of them, by observing the difference between the target temperature and the detected temperature.

When the timer cooking control method is input by the central operation unit 40M, the upper heater 163A and the lower heater 163B, or one of them, is energized for a set time. That is, the heating chamber control unit 159 does not limit the energization time according to the detection temperature data of the temperature sensor TS2.

After closing the door 114, when the central operation unit 40M (input key 43MS) of the input operation unit 40 is instructed to start cooking in the oven (heating chamber 113), the integrated control device MC controls the microwave heating. A drive command is issued to the unit 130, and the operation of the third cooling fan 128 and the fourth cooling fan 129 is started. The drive command signal may be output directly from the heating chamber control unit 159 to the third cooling fan 128 and the fourth cooling fan 129.

When the third cooling fan 128 is operated, air is sucked into the case A150 from the intake port F152F formed in the bottom plate 101U of the lower case 101. However, unlike the case of microwave cooking, the inverter circuit board 121 does not generate heat. Therefore, the cooling air RF5 enters the communication port B138B and the communication port A138A, respectively, without cooling the inverter circuit 121 substrate.

Then, the cooling air RF5 that has passed through the communication port A138A is blown out from the gap between the outer shell case of the temperature sensor 160 and the mouth edge of the mounting hole into the heating chamber 113 through the detection window 161.

On the other hand, the cooling air RF5 that has passed through the communication port A138A is guided to the passage 172. Then, while cooling the upper case 169, the communication port 173 is reached, and then the upper case 169 is introduced into the exhaust duct 102 (see FIG. 10).

On the other hand, the cooling air RF6 by the fourth cooling fan 129 passes through the heat radiating portion 122 of the magnetron 122 and reaches the inside of the duct 153. However, since the magnetron 122 is not driven, it does not generate heat. Therefore, the cooling air RF6 enters the void GP5R with almost no temperature rise.

Then, the cooling air RF6 is introduced into the heating chamber 113 from the introduction port 201 as shown in FIG. Therefore, the cooling air RF6 reaches the inner portion of the door 114.

The food or the like to be cooked in the heating chamber 113 may generate steam, oily smoke, or the like due to the radiant heat of the upper heater 163A or the lower heater 163B. As shown in FIG. 10, such steam, oil smoke, and the like are carried to the communication port 174 by the cooling air RF6 moving from the front portion of the heating chamber 113 to the rear portion.

After that, the cooling air RF6 is introduced into the exhaust duct 102 extending horizontally rearward from the communication port 174. Then, when the cooling air RF 6 exits the exhaust duct 102, the cooling air RF 6 passes through the exhaust port 20 and is discharged into the room while being attracted by the cooling air RF 5 rising upward.

In the first embodiment described above, after the main power switch 97 is turned on, the integrated control device MC changes the overall condition of the cooking cooker 1 up to a certain stage, and then temporarily the left operation unit 40L or the right operation unit 40R. When was operated, the subsequent induction heating control was entrusted to the control device 90. However, the range controlled by the integrated control device MC may be changed between the range controlled by the integrated control device MC and the IH control device 90.

Similarly, the range controlled by the integrated control device MC may be changed between the heating chamber control unit 159 and the microwave heating control unit 130.

For example, after the cooking menu of either induction heating, microwave heating, or oven (heating chamber) heating is selected, the IH control device 90, the heating chamber control unit 159, or the microwave heating control unit 130 can be used. Basically, it may be possible to perform a control operation related to heating.

In that case, when a new input is made by the input operation unit 40 (including heating stop), it is once controlled by the integrated control device MC, but when no input is made, IH control is performed as it is. Cooking may be executed by either the device 90, the heating chamber control unit 159, or the microwave heating control unit 130.

A specific example will be described below with reference to FIG. 31.
FIG. 31 is a flowchart illustrating the operation of the IH control device 90 when fried food cooking (automatic), which is a kind of induction cooking, is performed in the cooking device 1.

When "fried food (automatic cooking)" is selected in the cooking menu of induction heating, the temperature of the cooking oil put in the pan is monitored by the temperature detection circuit 93 and automatically of the IH coils 17L and 17R. The firepower is controlled.

When the user selects the fried food cooking (automatic) control menu, the IH control device 90 sequentially executes the preheating step, the fried food cooking step, and the heating power up step as shown in FIG. 31. Further, on the display screen 30D of the integrated display unit 30, information indicating necessary information and reference information (for example, an estimated time required for preheating) appears in characters, figures, and the like. It is also displayed that the priority cooking is such that the electric power is not limited (suppressed) by the electric power control unit 72.

Therefore, during the cooking of the fried food, the user can recognize that the electric power is preferentially secured even if the microwave heating or the oven heating is used.

In the preheating process, when the target oil temperature set by the user is 180 ° C., the inverter circuit 81R (or 81L) is started to be driven at a predetermined thermal power value (maximum 1500 W) in the preheating process, and the oil temperature is rapidly increased. Rise from room temperature (eg, 20 ° C.) to 180 ° C., the target temperature T1.

Since this temperature rise is monitored in real time by the temperature detection circuit 93 described above, when the temperature detection circuit 93 detects that the target temperature T1 (first temperature) has reached 180 ° C., the IH control device. 90 adjusts the induced heating amount, that is, the inverter output, and tries to maintain the target temperature as it is (based on such temperature detection information, the operation of automatically adjusting the high frequency thermal power to approach the target temperature is performed. Hereinafter referred to as "temperature feedback control").

After that, a display request command is issued to the integrated control device MC, and a voice guide such as "The temperature of the oil has reached an appropriate temperature. Please put in the ingredients" is given to the user via the voice synthesizer 95.

When the user puts an ingredient, for example, a frozen croquette, into the oil, the oil is rapidly cooled by the cold ingredient from the time of the addition, so that the temperature drops sharply as shown in FIG. 31. However, since the temperature detection circuit 93 monitors the movement of such a temperature drop, it immediately raises the thermal power of the inverter circuit 81R (81L) to a predetermined thermal power of 1500 W or 1800 W and drives it, so that the oil temperature rises again. (Temperature feedback control). In this way, as soon as the target temperature T1 is reached again (or after a predetermined time has elapsed), the process shifts from the fried food process to the heating power increasing process.

In the thermal power up step, the oil temperature is controlled to be maintained between 225 ° C. of the second temperature T2, which is higher than the target temperature T1, and 230 ° C. of the upper limit temperature (third temperature) T3 higher than this. The device 90 controls the inverter circuit 81R (81L).

As shown in FIG. 31, the thermal power value is intermittently driven at about 900 W. The process after the temperature reaches the third temperature T3 is called "fried food finishing process", and is an important process for finishing the fried food crisply. If you do not cook with sufficient heat in such a process to increase the heat, you will not be able to make fried food well. Since the fried food process is not limited to a predetermined time, if the user presses the input key 44R (or the input key 45L), all the fried food cooking is completed.

As shown in FIG. 31, in the (automatic) fried food cooking control menu, the process from the fried food cooking process to the heating power up process is defined as the "priority cooking menu execution time zone", and other execution time zones are defined. Power is not reduced by starting the heating source or changing the operating conditions. That is, the IH control device 90 for this induction heating always grasps whether or not the cooking menu being executed is in the "execution time zone of the priority cooking menu", and if it is in the execution time zone, the execution time zone is the same. It has a function to notify the outside to that effect.

As is clear from the above explanation, every time a specific heating process is entered, the integrated control device MC does not issue a control signal to the IH control device 90, and the progress of the heating process is all the IH. It is left to the control of the control device 90.

Next, the relationship between the integrated display unit 30 and various input keys of the central operation unit 40M, the right operation unit 40R, and the left operation unit 40L will be described with reference to FIGS. 32 to 38.

FIG. 32 is an explanatory diagram showing changes in the display contents of the integrated display unit 30. FIG. 33 is a plan view of the left operation unit 40L and the left side display unit 31L before and after the start of induction cooking. FIG. 34 is an explanatory diagram showing changes in the display contents of the integrated display unit 30 and the left side display unit 31L. FIG. 35 is an explanatory diagram 1 showing a change in the display content of the integrated display unit 30. FIG. 36 is an explanatory diagram 2 showing a change in the display content of the integrated display unit 30. FIG. 37 is an explanatory diagram 3 showing a change in the display content of the integrated display unit 30. FIG. 38 is an explanatory diagram 4 showing changes in the display contents of the integrated display unit 30.

FIG. 32 will be described. Since the integrated display unit 30 is not activated in the state where the main power switch 97 is turned off, no information is displayed.
In the state where the main power switch 97 is turned on, the integrated control device MC displays the display screen 1 of FIG. 32 on the integrated display unit 30 after performing a self-diagnosis such as the presence or absence of an abnormality as described above.

In the display screen 1 of FIG. 32, 30A is a display statement notifying that the power is on. 30B is two-dimensional information (two-dimensional code) for guiding to a dedicated recipe posting site via the Internet. 30C is a sentence explaining the meaning of the two-dimensional code. The two-dimensional information 30C and the display sentence 30A are one of the "standby common information" 30N referred to in the present invention.

After the display screen 1 of FIG. 32 is displayed, the display screen 2A or 2B may be automatically displayed. On the display screen 2A, "Caution for sudden boiling" is one of the caution displays. This "sudden boiling" is a phenomenon in which when an object to be cooked such as curry or stew is heated, the inside of the object to be cooked is overheated above the boiling point and suddenly causes a violent boiling. Say. As steam erupts from a heated liquid, hot droplets may scatter and be dangerous. It is said that the timing and cause of bumping is the mixing of foreign matter from the outside or the impact. Therefore, as shown on this display screen 2, when a metal pot or the like containing the food to be cooked is placed on the top plate 15 and induced to be heated, caution is alerted when the food to be cooked is stirred. Attention is displayed. This cautionary display information is a kind of "standby common information" 30N referred to in the present invention.

On the display screen 2B, 30E is a caution display warning that the inside of the heating chamber 113 has a high temperature and does not come into contact carelessly. When the integrated control device MC detects that the heating chamber 113 has not been sufficiently cooled after the oven cooking is performed in the heating chamber 113, the state of the display screen 2 is automatically switched. Although the display screens 2A and 2B cannot be displayed at the same time, they may be displayed alternately at intervals of several seconds to call attention to both bumping and high temperature notification. The voice synthesizer 95 may be used to call attention to the display screens 2A and 2B in parallel by voice.

As is clear from the display screens 1 to 2A and 2B of FIG. 32, these displays are performed by using the entire display screen 30D. That is, instead of partially displaying in any of the first area 30L to the third area 30R described above, the three areas 30L to the third area 30R cannot be identified in order to secure the widest possible display area. In this way, the integrated display is performed so that the user can see that the integrated display unit 30 is displayed as a whole.

The display screens 1 to 2A and 2B are the stages of ST3 in the operation step of FIG. 24.
After a certain period of time, for example, 10 seconds has elapsed from the display time of the display screens 1 to 2A and 2B, the display content changes to prompt the selection of the heating source (heating means) (operation step ST4 in FIG. 24).

Therefore, the case of induction heating in the upper unit 100 will be described next. In the operation step of FIG. 24, it is the stage of ST6.

FIG. 33 is a plan view of the left display unit 31L and the left operation unit 40L for the left heating source 17HL. Before pressing the input key 43L1 for selecting cooking by the left heating unit 17HL, the state is shown in FIG. 33 (A).

When the input key 43L1 is pressed, the integrated control device MC detects that the user has selected the left heating source 17HL, causes the individual light emitting unit 27L3 to emit light as shown in FIG. 33 (B), and inputs an operation input. Display that it has been accepted.

Since the input key 43L4 for selecting timer cooking is also waiting for input, the individual light emitting unit 27L1 is blinked. Further, since the selection of the control menu is also in the state of waiting for input, the individual light emitting unit 27L2 directly behind the input key 44L is blinked. In FIG. 33B, the star-shaped figure indicates that the light emitting display unit 27 has turned on or blinked.

If the default heating power is set to "3", the heating power display unit 67L indicating the heating power stage during induction heating causes the light emitting unit of the heating power display unit 67L to continuously emit light from the left side (or until the heating power 3 is indicated). Change the blue color to red) and display the amount of firepower to the user.

When the user changes to a thermal power that is not the default setting, pressing the input key 43L2 or 43L3 reduces or increases the thermal power by one step each time the input key is pressed, and the light emitting unit of the thermal power display unit 67L (correspondingly Or the range of the red light emitting part) is expanded from the left side to the right or reduced to the left side, and the adjustment state of the thermal power is displayed to the user.

Next, FIG. 34 will be described.
FIG. 34 is an operation explanatory view of the left operation unit 40L and the left side display unit 31L of the cooking cooker 1.
In FIG. 34, the figures (A) to (C) drawn on the left side are schematic views of the left operation unit 40L and the left side display unit 31L, and the state before the start of the operation is shown in FIG. 34 (A). Is.

As described with reference to FIG. 33, when the input key 43L1 is operated, the light emitting display unit 27L3 emits light as shown in FIG. 34 (B).
In the state of FIG. 34 (B), the light emitting display unit 27L4 is also lit, and it can be seen that the input function is effective for both the input keys 43L2 and 43L3. Therefore, if the input key 43L2 on the left side is pressed twice, the thermal power is reduced. The increase / decrease in the thermal power can be seen from the light emitting state of the thermal power display unit 67L immediately behind.

Furthermore, at the stage of thermal power level 1, if the input key 43L2 is pressed once, it means that the temperature is specified below the thermal power level 1, but the integrated control device MC judges that the control mode of "heat retention" is specified, and the figure shows. The display screen 3A of 34 is displayed on the display screen 30D of the integrated display unit 30.

As can be seen from the display screen 3A, the display screen 30D displays a "figure of a container such as a pot" in the first area 30L, and the second area 30M and the third area 30R are combined into a horizontally long display area. In the space where the second area 30M and the third area 30R are combined, the characters "heat insulation (left IH)" are displayed, indicating that the heat insulation temperature is about 80 ° C. The explanation 30F indicates that the control menu is recommended for soups and the like. At the stage of this display screen 3A, nothing is displayed on the left side display unit 31L.

Next, when the input key 44L is pressed in the state of FIG. 34 (B), one control menu is selected from the control menu group each time the input key 44L is pressed, and the display screen 3B is displayed. In the example of the display screen 3B, it is shown that "fried food" is selected. After a lapse of a certain period of time in the state of FIG. 34 (B), the control menu of the left heating unit 17HL is confirmed as "fried food", and the driving of the IH coil 17L is started.

In the case of the display screen 3B, since the default temperature is set to 180 ° C., the characters “fried food 180 ° C.” are displayed on the left side display unit 31L as shown in FIG. 34.
This temperature of "180 ° C" means that the cooking oil is heated by the IH coil 17L and maintained in the vicinity of 180 ° C, and when the temperature reaches 180 ° C, it is notified by voice by the voice synthesizer 95. In addition, the integrated display unit 30 displays that "the preheating temperature has been reached" and prompts the input of foodstuffs and the like.

If it is desired to change the preheating (target) temperature of the fried food, the temperature can be lowered by the input key 43L2 or raised by the input key 43L3.

As can be seen from the display screen 3B, the display screen 30D has a horizontally long and wide display area in which the second area 30M and the third area 30R are combined, and the second area 30M and the third area 30R are combined. In the space provided, a cautionary statement 30G indicating that the preheating is started and that the cooker 1 is not separated from the side during the preheating operation is displayed.

Next, in the state of FIG. 34 (B), when the input key 44L is pressed and "appropriate temperature" is selected as another control menu, the display screen 3C is displayed. As shown on the display screen 3C, the control menu "suitable temperature" is a recommended control mode for heating a pot or the like to a set temperature (default temperature is 180 ° C.) and for tamagoyaki or the like. The testimonial 30H is shown so that such a meaning can be understood. At the stage of this display screen 3C, the character information "preheating 180 ° C." is displayed on the left side display unit 31L.

Next, FIG. 35 will be described.
FIG. 35 is a schematic view illustrating the display operation of the integrated display unit 30 when the central operation unit 40M of the cooking cooker 1 is operated.
In FIG. 35, the display screen 4ST is a default display screen defined by the integrated control device MC.

As described with reference to FIG. 15, when the input key 43MC is operated, the display screen 4ST of FIG. 35 is displayed on the integrated display unit 30.
As is clear from the display screen 4ST, a specific sentence 30J indicating the name of the control menu "warm" is displayed in a large size in the center of the first area 30L in the front-rear direction.

The word "oven" is displayed behind the specific sentence 30J of "warm" displayed in the center of the first area 30L, and conversely, the word "range manual" is displayed slightly smaller on the front side.
And when the user selects the control menu, the next candidates are "oven" and "manual range". If the input key 43M1 at the position corresponding to the first area 31L is pressed once at this stage, the character "warm" (specific sentence 30J) changes to "range manual".
Further, when the input key 43M1 at the position corresponding to the first area 31L is pressed once, the character "warm" changes to "oven".

In FIG. 35, the display screen 4ST, which is the default display screen, displays the target temperature information 30T of “80 ° C.” in the second area 30M. When microwave heating is performed at this target temperature, when the temperature of the food is 80 ° C., the microwave heating is automatically stopped when the temperature sensor TS1 detects it.

In order to raise the target temperature (80 ° C.) of the second area 30M to 85 ° C., the input key 43M2 on the right side, which is located immediately before the second area 30M, is operated once. On the contrary, when it is desired to lower the temperature to 75 ° C., the input key 43M2 on the left side may be operated once.

A mountain-shaped symbol 30UP is displayed above the number of the target temperature (80 ° C.) in the second area 30M. Also, below the number at 80 ° C., a downwardly pointed (V-shaped) symbol 30DN is displayed.

Since this symbol 30UP and the shape of the input key 43M2 (on the right side) of the integrated display unit 30 are similar, the user can operate the input key 43M2 on the right side to raise the temperature, thermal power, etc. Is easy to understand.

On the contrary, since the shape of the input key 43M2 (on the left side) of the integrated display unit 30 is similar to that of the 30DN, the user can operate the input key 43M2 on the left side when lowering the temperature, thermal power, etc. Is easy to understand. This correspondence rule is also applied to the relationship between the display of the third area 30R and the pair of left and right input keys 43M3. In this way, we have adopted a device to avoid operation mistakes (wrong input keys) during user input operations.

In FIG. 35, 30K is a heating source display unit that indicates in characters that the heating source is a microwave heating source 189. As described above, 30P is reference information indicating that it is a recommended control menu for warming side dishes and the like. The content of this reference information may be another additional information 30Q, or two or more types of information may be alternately displayed on the display screen 30D for several seconds each.

Next, FIG. 36 will be described.
FIG. 36 is another schematic view illustrating the display operation of the integrated display unit 30 when the central operation unit 40M of the cooking cooker 1 is operated.
In FIG. 36, when the control menu is set to “range manual”, the display screen 5ST is the default display screen defined by the integrated control device MC.

As described with reference to FIGS. 15 and 35, when the input key 43MC is operated, the display screen 4ST of FIG. 35 is displayed on the integrated display unit 30. Next, when the input key 43M1 on the left side of the central operation unit 40M is operated many times, the specific sentence 30J changes to "range manual", and the display screen 5ST of FIG. 36 is displayed on the integrated display unit 30. ..

As is clear from the display screen 5ST, the specific sentence 30J of the control menu "range manual" is displayed in large size in the center of the first area 30L in the front-rear direction.

On the display screen 5ST of FIG. 36, the microwave output value (watt value) information 30X of "500W" is displayed in the second area 30M. Further, in the adjacent third area 30R, the microwave heating time information 30MY of "1 minute 00 seconds" is displayed. As can be seen from this display screen 5ST, since it is known that the microwave heating source 189 is used from the beginning in this "range manual" control menu, it is as shown in FIG. 35 (with the microwave heating source 189). The heating source display unit 30K (which indicates that there is a character) may not be displayed.

If you want to lower the microwave output value (watt value) of 500W in the second area 30M of the display screen 5ST by one step to 200W, you can operate the input key 43M2 on the left side once.

Similarly, in order to lengthen the heating time of the second area 30R to 1 minute and 10 seconds, the input key 43M3 on the right side, which is located immediately before the third area 30M, is operated once. On the contrary, when it is desired to shorten the heating time by one step to 50 seconds, the input key 43M3 on the left side may be operated once.

In the display screen 5ST of FIG. 36, the mountain-shaped symbol 30UP is not displayed above the number of the output (500W) of the second area 30M. Also, below the number of 500 W, a downwardly pointed (V-shaped) symbol 30DN is displayed.

The display screen 5DNN in FIG. 36 shows the minimum thermal power (100 W) and the shortest time (10 seconds), and the display contents of the first area 30L are omitted.
The symbol 30UP is displayed only on the upper side of the minimum thermal power (100W) of the display screen 5DNN, indicating that only thermal power larger than this thermal power can be selected. Similarly, the symbol 30UP is displayed only on the upper side of the number of the shortest time (10 seconds), and the symbol 30DN is not displayed. In other words, the symbol 30UP also indicates that a shorter time cannot be selected.

Next, FIG. 37 will be described.
FIG. 37 is still another schematic view illustrating the display operation of the integrated display unit 30 when the central operation unit 40M of the cooking cooker 1 is operated.
When the input key 43M1 on the left side corresponding to the first area 30L is operated once in the state of the display screen shown in FIG. 36, as shown in FIG. 37, the control menu is changed from "range manual" to "boiled leaf vegetables". Can be changed to.

The display screen 6ST in FIG. 37 is the default display screen. In the first area 30L, the specific sentence (name) 30J of the control menu, "Hanashita boiled" is displayed in large size.
In the second area 30M, the information 30V indicating the microwave output level is displayed as "standard", and if cooking is started as it is, it will be heated at 500W. The microwave output value in the case of "standard" may be 500 W, but may be other than this. That is, when the microwave heating source 9 is used, the "standard" of the thermal power level is different for each control menu and is not always the same output (for example, 500 W).

In the first area 30L of FIG. 37, as described with reference to FIG. 35, a heating source display unit 30K indicating that the heating source is the microwave heating source 189 is displayed. As described above, 30P is a testimonial indicating that the control mode is recommended for warming side dishes and the like. The content of this testimonial may be another additional information 30Q, or two or more types of information may be alternately displayed on the display screen 30D for several seconds each.

Next, FIG. 38 will be described.
FIG. 38 is still another schematic view illustrating the display operation of the integrated display unit 30 when the central operation unit 40M of the cooking cooker 1 is operated.
FIG. 38 shows a scene in which a control menu called “RG cooking” is selected.
As described above, RG cooking is "range grill cooking" in which microwave heating and oven heating are combined and cooked using the heating chamber 113. A pattern in which microwave heating is performed first to heat food to some extent and then heated by the upper heater 163A and the lower heater 163B, a pattern in which heating is performed in the reverse order, and a pattern in which microwave heating and heater heating are performed at the same time. There are three types. Note that "simultaneous" here does not mean that the timings of both the start and end of heating are the same, but also includes the case where there is a time zone in which the heating operations overlap.

In the display screen 7ST1 shown in FIG. 38, heating control is performed in which both the microwave heating source 189 and the oven heating source 188 are first driven simultaneously to heat for 1 minute, and then the oven heating source 188 alone is used for heating for 5 minutes. It can be seen that it is a time control) pattern.
The reason why the abbreviated form "RG" is used instead of the term "range &grill" is to minimize the number of characters that can be displayed in the first display area 30L. This is because if an attempt is made to display a larger number of characters, the occupied area of the first area 30L will increase.

In the display example shown in FIG. 38, the heating time information 30S is displayed in minutes in the second area 30M, and the heating time information 30GY for the subsequent grill cooking is also displayed in minutes. The heating time information 30S shown in the first area 30L and the heating time information 30GY in the third area 30R can be appropriately changed by the input keys 43M2 and 43M3 of the central operation unit 40M.

In FIG. 38, the display screen 7ST2 is first heated by the microwave heating source 189 alone for 1 minute (microwave output 500 W), and then heated only by the oven heating source 188 for 5 minutes, which is a heating control (time control) pattern. This is the case. This display screen 7ST2 is a default display screen.

Next, FIG. 39 will be described.
FIG. 39 is a schematic plan view illustrating the display contents of the display screen 6ST shown in FIG. 37 and the operation of the central operation unit 40M.

As shown in FIG. 39, the individual light emitting units 27M1 to 27M6 are arranged in the central operation unit 40M, and when the main power switch 97 is turned on, the individual light emitting units 27M1 to 27M1 are arranged by the display unit drive circuit 63. The 27M4 emits light with a unified emission color.

After that, when the selection input key 43MC of the control menu is further operated, the display screen 6ST shown in FIG. 37 is displayed by default in the first area 30L.
At this display stage, a total of four input keys 43M1 to 43M2 corresponding to the first area 30L and the second area 30M can all accept inputs. Therefore, the two individual light emitting units 27M3 and 27M4 corresponding to the four input keys 43M1 to 43M2 continue to emit light.

On the other hand, after the display screen 6ST, the display screens 6UP1, 6DN1, etc. are displayed as shown in FIG. 39, the individual light emitting unit 27M6 corresponding to the input key 43MS for starting is shown in FIG. 39. As shown, it changes from continuous emission to blinking. Then, the existence of the input key 43MS is emphasized by light. When the user touches the input key 43MS, the cooking operation is started.

As described above, in the first embodiment, when the input functions of the input key 43M1 as the menu selection unit and the input key 43MS as the start selection unit are effective, the first light emission mode (continuous light emission). A light emitting means (display unit drive circuit 63) for emitting light of each light emitting unit 27M1 to 27M6 is provided.
When the reference information 30P is displayed, the integrated control unit MC has a configuration in which only the light emitting unit 27M6 corresponding to the start selection unit (input key 43MS) emits light in the second light emitting mode (blinking). be.

Because of the above configuration, the user can easily identify the state of waiting for the start command of cooking by the blinking of the light emitting unit 27M6. The light emitting unit 27M6 also supports a touch-type input key 43MT that can stop the operation of microwave heating and oven heating. Therefore, when the light emitting unit 27M6 is emitting light, the input key 43MT is also supported. The input function is effective, and a command to stop heating can be sent by touch operation.

At the stage when the main power switch 97 is turned on, the display unit drive circuit 63 may cause only the light emitting unit 27M6 corresponding to the input key 43MS, which is the start selection unit, to blink from the beginning. Further, the other light emitting units 27M1 to 27M4 may emit light continuously and emit light in a form different from that of the input key 43MS of the start selection unit.

It is the IH control device 90 that controls the induction cooking in response to the command from the integrated control device MC. Further, it is the control device 105 that controls both the microwave heating source 189 and the oven heating source 188. This control device 105 is an assembly of the heating chamber control unit 159 and the microwave heating control unit 130 described in the first embodiment.

The two control devices 90 and 105 described above may be called a slave (SLAVE) microcomputer because they perform predetermined control to the integrated control device MC according to a command and return the processing result to the integrated control device MC. In this case, the integrated control device MC is called a master microcomputer.

The remaining three of the above-mentioned six control devices will be described below.
The first is a right-hand input control device 23 that processes the input of the right-hand touch key group arranged in the right-hand operation unit 40R and the display of the display unit 31R in the input operation unit 40.

The power switch control device 28 detects the operation of the operation button (operation unit) 98 of the main power switch 97 arranged in the input operation unit 40, and determines ON / OFF of the power supply.

In FIG. 40, 106A is a plug connected to a commercial (alternating current) power supply 99. Power with a voltage of 200 V, 50 Hz or 60 Hz is guided to the filter circuit board 54 via the power cord 106. The filter circuit board 54 is built in the upper unit 100.

The filter circuit board 54 has a main relay 107 for turning on and off the main power of the cooking cooker 1 and a sub-relay (not shown). In FIG. 40, only the main relay is schematically shown.

The main relay 107 receives a predetermined relay control signal from the integrated control device MC that controls the entire heating cooker 1 and executes an opening / closing operation. As will be described later, the sub-relay receives a relay control signal from the power switch control means 28 and executes an opening / closing operation. The power switch control means 28 has a function of detecting the operation of the operation button 98 of the main power switch 97 and determining ON / OFF of the power supply. The main power switch 97 is composed of the main relay 107 and the sub relay.

Etc. are implemented. The central operation board 32 is made of a plastic material having excellent electrical insulation.

Reference numeral 55 is a power supply circuit board to which power of a commercial power source is supplied from the filter circuit 54. As shown in FIG. 40, the power supply circuit A34 and the rectifier circuit 35 to which the power is applied via the rectifier circuit 33 are provided. It is provided with a power supply circuit B36, to which electric power is applied via the power supply circuit B36. The two power supply circuits A34 and the power supply circuit B36 convert the power of a voltage of 200V into a low voltage direct current such as 24V, 18V, 6V, 5V and the like.

The 5V electric power is supplied as a power source for the integrated control device MC, the IH control device 90, the control device 105, the right side input control device 23, the left side input control device 24, and the power switch control device 28.

From the filter circuit 54, AC power having a voltage of 200 V is applied to the inverter circuit board 80. Reference numeral 90 denotes an IH control device that controls overall induction heating, and is mainly composed of a microcomputer.

The IH control device 90 transmits a drive signal to the drive circuits 37L and 37R that drive the IGBTs 79a and 79b in the inverter circuits 82L and 82R. The two drive circuits 37L and 37R operate with the power of 18V supplied from the power supply circuit A34 and the power supply circuit B36, and control the IGBTs 79a and 79. As a result, the drive frequencies of the inverter circuits 81L and 81R are controlled.

For example, the drive circuit A37R detects the conduction time of the power switching element 93 (semiconductor switching element) (IGBT79a, 79b) and switches the conduction time to lower the drive frequency of the inverter circuit 81R and reduce the thermal power. Or, conversely, control is performed to increase the driving frequency and increase the thermal power. These drive frequency commands are issued by the IH controller 90.

77a is an input current detection unit installed on the commercial power supply side of the inverter circuits 81L and 81R, and 77b is an output current detection unit that detects the power on the output side of the inverter circuits 81L and 81R.
The detection values of the input current detection unit 77a and the output current detector 77b are input to the IH control device 90.

In the initial stage during induction heating, the IH control device 90 determines the material of the object to be heated.
For example, when the drive frequency is changed from one drive frequency to another, the change in the input current value is observed to determine whether the material of the object to be heated such as a pot is magnetic metal, non-magnetic stainless steel, aluminum, or the like. Then, the drive frequencies of the switching elements (IGBT) 79a and 79b are automatically adjusted to appropriate values. When the material of the object to be heated is determined to be non-magnetic stainless steel, it is driven at a drive frequency (for example, 31 kHz) higher than the drive frequency (for example, 23 kHz) when it is determined to be iron.

The door open / close detection mechanism 131 includes one switch that is opened / closed according to the opening / closing operation of the door 114, and a monitor switch that detects that the switch is correctly opened / closed. This point is the same as that described in the first embodiment.

The 120P is a power supply circuit unit of the microwave heating device 120, and generates AC power as a low voltage (for example, 24V and 5V) power source from the power of the commercial voltage (200V) supplied from the filter circuit 54. The electric power having a voltage of 5 V is supplied as a power source for the control device 105, and the electric power of 24 V is supplied to the drive circuit 177 of the third cooling fan 128 and the fourth cooling fan 129, respectively. Further, 24V electric power is supplied as a driving power source for the antenna driving motor 126.

The upper heater 163A and the lower heater 163B that heat the heating chamber 113 are controlled to be energized by opening and closing the relays 178A and 178B by the control device 105. The relays 178A and 178B may use a semiconductor switching element capable of finely controlling the energization rate, but in the second embodiment, since only ON-OFF control is performed, a relay is adopted. There is. The upper heater 163A and the lower heater 163B are operated by applying the same voltage of 200V as the commercial power supply.

The 132M is a door open detection switch that constitutes a part of the door open / close detection mechanism 131. The switch itself is installed inside the door open / close detection mechanism 131, but in FIG. 40, it is drawn at a different position to show that the open / close signal is input to the control device 105.

Reference numeral 160 is an infrared sensor for measuring the temperature of food or the like in the heating chamber 113, and TS1 is a contact type sensor for measuring the temperature of the magnetron 122 of the microwave heating device 120. All the temperature detection data of these sensors 160 and TS1 are input to the control device 105.

121A is an inverter circuit that supplies high frequency power to the magnetron 122, and oscillation is controlled by a relay 182 inserted in the power supply side circuit. The relay 182 is opened and closed by the control device 105.

60P and 61P are drive circuits for driving the first cooling fan 60 and the second cooling fan 61, respectively. The drive circuits 60P and 61P operate in response to a command from the IH control device 90.

Although the temperature sensor for monitoring the temperature of the integrated display unit 30 and the input operation unit 40 is not shown in FIG. 40, in reality, such a temperature sensor is installed and always (every fixed time) during cooking. The temperature measurement data is acquired by the integrated control device MC and monitored so that the temperature does not become abnormal.

Reference numeral 38 is a left operation board, which is installed on the left side of the central operation board 32 and is made of an electrically insulating material. The left side input control device 24 and the left side display unit 31L are attached to the left side operation board 38. The left operation board 38 and the center operation board 32 are installed adjacent to each other so as to be lined up on substantially the same plane.

Next, the central operation unit 40M and the integrated display unit 30, which are one of the features of the second embodiment, will be described.
As shown in FIG. 41, the display screen unit 300 of the integrated display unit 30 has a fourth area 303 in addition to the first area 30L to the third area 30R. The first area 30L to the third area 30R are the same as those described in the first embodiment, and are display areas in which a substantially display area can be changed. However, the fourth area 303 has a fixed area, and is formed in an elongated shape so as to lie in contact with the rear of the first area 30L to the third area 30R.

The surface of the integrated display unit 30 is covered with a glass plate, and substantially the entire area except the peripheral portion is a capacitive touch panel that senses the contact of the user's finger. Therefore, the touch panel portion is hereinafter referred to as an "operation panel" 311. When the integrated display unit 30 is arranged under the top plate 15, the glass plate is the top plate 15.

The entire operation panel 311 is divided into a "touch restriction portion" corresponding to the fourth area 303 and a portion (touch recommended portion) that functions as the first area 30L to the third area 30R.
Reference numeral 310 denotes an electrode formed on the back side of the touch-restricted portion by vapor deposition, printing, or the like. When the operation panel 311 is composed of a part of the top plate 15, the electrode 310 is formed on the back side of the top plate 15 by means such as thin film deposition or printing.

The electrode 310 transmits a contact detection signal to a contact detection unit (not shown), and a user is placed above the electrode 310 while the input operation unit 40 is activated by the integrated control device MC. The touch is detected from the change in capacitance.

Even when the metal pan or the like of the object to be heated N is projected and placed up to the position of the integrated display unit 30 (abnormal state), the excessive approach of the object to be heated N can be detected by the electrode 310. Therefore, the integrated control device MC can detect an abnormal placement such that the object to be heated N abnormally approaches the integrated display unit 30 or covers the integrated display unit 30, and issues an alarm.

The electrode 310 and the contact detection unit (not shown) function as a safety device so that the user does not touch the "touch restriction portion". That is, it is possible to minimize the user's contact with the top plate 15, which becomes hot during induction heating.

As is clear from FIG. 41, the various input keys 43M1 to 43M3 provided in the central operation unit 40M of the first embodiment are unnecessary in the second embodiment and are therefore deleted.
Instead, it includes a touch panel input device 301 described below in FIG. 43 and a touch gesture determination device 302 that receives operation information on the touch panel.

The integrated display unit 30 of FIG. 42 has a size larger than that of the integrated display unit 30 of the first embodiment. Generally, looking at the standard lineup of TFT liquid crystal modules used in this type of display, the sizes are 3.5 inches, 3.97 inches, 4.3 inches, 4.6 inches, 5.0 inches, etc. The ones are offered. When the one of the first embodiment is, for example, 3.5 inches or 3.97 inches, in the second embodiment, the one having a screen size one step or two steps larger than that can be used. However, as shown in FIG. 43, the temperature of the top plate 15 tends to increase as it approaches the left heating portion 17HL and the right heating portion 17HR. Therefore, the integrated display unit 30 is arranged on the front FR side from the first embodiment so as not to approach the high temperature notification unit 69.

By omitting the various input keys 43M1 to 43M3 of the first embodiment, the integrated display unit 30 having a large display area can be obtained. Therefore, as shown in FIG. 42, even in the second area 30M and the third area 30R, more information such as the target temperature and the heating time, which is one of the conditions in the control menu, can be displayed.

Reference numeral 30Y in FIG. 42 is a candidate display unit capable of displaying the next candidate of "control conditions" such as the target temperature and the heating time. As shown in FIGS. 42 and 43, the candidate display unit 30Y displays the candidate temperature that can be selected next to the target temperature information 30T.

As shown in FIG. 43, when the target temperature information displayed in the second area 30M is “180 ° C.”, the candidate display unit 30Y has the target temperature information 30T1 “185 ° C.” and “175 ° C.”. The target temperature information 30T2 is displayed.

Further, in the third area 30R, when the displayed heating time information is "10 minutes", the candidate display unit 30Y has a heating time information 30GY1 (during grill cooking) of "10 minutes 30 seconds". , "9 minutes 30 seconds" heating time information 30GY2 is displayed.

The FG shown in FIG. 43 indicates the fingertip of the user. The user can change the displayed control menu to the next candidate control menu by moving the fingertip FG to the front FR or the rear BK while touching the first area 30L to the third area 30R with the fingertip FG. can.

In FIGS. 43 to 45, 27M7 is a light emitting unit that constitutes a part of the light emitting display unit 27M. In the first embodiment, the heating stop input key 43MT shares the light emitting unit 27M6 corresponding to the start selection unit (input key 43MS), but in the second embodiment, the heating stop input key 43MT is shared. A light emitting unit 27M7 is provided exclusively for the above. The light emitting unit 27M7 may be continuously lit normally before the start of heating, and may be changed to blinking to emit light after the heating operation is started. Since input by the input key 43MT is not required before the start of the heating operation, the input function is disabled, and from the start of the heating operation, the user emits light in the form of continuous light emission or blinking as described above. Can be easily visually confirmed.

The touch panel input device 301 and the touch gesture determination device 302 will be described with reference to FIG. 44.

The first area 30L to the third area 30R constituting the operation panel 311 are touch gesture input means for accepting the touch gesture operation performed by the user. Further, the touch gesture operation is an information input operation by a specific movement such as a user's fingertip FG.

The touch gesture operation is a tap that taps the surface of the operation panel 311 with a fingertip, a flick that flicks the surface of the operation panel 311 with a finger, and an operation of tracing the surface of the operation panel 311 with a finger (sliding a finger). Can include certain swipes. However, in the second embodiment, it is determined that only the touch gesture operation of moving the user's fingertip FG in the front-back direction is effective. This will be described in detail later.

The touch gesture operation is dragging, which is an operation of dragging the fingertip FG, pinch-in, which is an operation of narrowing the distance between fingertips while pinching with multiple fingertips on the surface of the operation panel 311. There are also pinch-out operations that are expansion operations, but these are also identified by the operation determination unit 313 as invalid touch gesture operations.

The operation panel 311 receives a specific touch gesture operation performed by the user, and outputs input operation information (hereinafter referred to as "touch information") IP1 corresponding to the touch gesture operation.

Immediately below the operation panel unit 311 is a display panel 320 that is arranged so as to overlap the operation panel unit 311 and displays an image of the operation screen showing various information (including control conditions such as temperature and thermal power) related to the control menu. It is arranged. The display panel 320 is, for example, a liquid crystal display. As shown in FIG. 41, the display panel 320 has a display screen unit 300.

As shown in FIG. 44, the touch gesture determination device 302 has an operation determination unit 313 and a notification unit 318.

The operation information input unit 312 receives the touch information IP1 output from the operation panel unit 311. The operation information input unit 312 outputs the input information IP2 corresponding to the received touch information IP1 to the operation determination unit 313. The input information IP2 is information corresponding to the touch information IP1 and may be the same information as the touch information IP1.

The operation determination unit 313 receives the touch information IP1 from the operation information input unit 312, and outputs the selection value signal IP3 as output information to the notification unit 318. The selection value signal IP3 output from the operation determination unit 313 is a selection value signal determined by the operation determination unit 313 based on the touch information IP1. In the second embodiment, the selection value signal serves as information for determining the control menu.

The operation determination unit 313 determines the type and content of the touch gesture operation by the user from the received touch information IP1.
The operation determination unit 313 has a gesture mode determination unit 314, a gesture input information determination unit 315, and a gesture area determination unit 316.

The reference parameter storage unit stores at least slider mode parameters among user gestures. One example of the parameter is a parameter determined based on any one or a combination of two or more of the movement amount of the touch gesture operation in a predetermined time, the speed of the touch gesture operation, or the touch time.

The gesture mode determination unit 314 specifies the gesture mode of the input information IP2 with reference to various parameters of the reference parameter storage unit. The gesture input information determination unit 315 determines the selection value signal IP3 according to the value setting method in the gesture mode specified by the gesture mode determination unit 314.

The gesture area determination unit 316 identifies in which area of the first area 30L to the third area 30R the user has performed the touch gesture operation.

The notification unit 318 receives the selection value signal IP3 from the operation determination unit 313 for each area of the first area 30L to the third area 30R by the operation determination unit 313. Therefore, the notification unit 318 switches the individual display information of the first area 30L to the third area 30R, and outputs the information to the speech synthesizer 95 to notify about such switching.

The display unit drive circuit 63 receives the selection value signal IP4 from the touch gesture determination device 302. The selection value signal IP4 has the same contents as the selection value signal IP3.
The display unit drive circuit 63 switches the display content of the display panel 320 of the integrated display unit 30 according to the determination result of the touch gesture determination device 302. That is, as shown in FIG. 44, the display unit drive circuit 63 outputs the image signal IP5 of the operation image to be displayed on the display panel 320 to the display panel 320.

In FIG. 44, the touch panel input device 301 and the touch gesture determination device 302 are shown in the form of a hardware (H / W) configuration. However, the touch gesture determination device 302 shown in FIG. 44 is realized by the right side input control device 23. The software storage device of the right side input control device 23 is provided with a storage unit for storing the touch gesture determination program, and the touch gesture determination program stored in the storage unit is transferred by the microcomputer of the right side input control device 23. I'm running it.

In FIG. 44, 319 is a reference information storage unit. The reference information 30P and the additional information 30Q described in the first embodiment are stored in the reference information storage unit 319.

Since the cooking device 1 of the second embodiment is configured as described above, when starting cooking, the operation key 98 of the input operation unit 40 is pressed in order to first turn on the main power switch 97. For example, if it is held down for a few seconds, the power switch control device 28 detects this operation and closes the main relay 107 in the filter circuit board 54.

Therefore, the power of the commercial power supply is supplied from the filter circuit board 54 to the power supply circuit board 55. Then, a power supply having a predetermined voltage is generated by the power supply circuit A34 and the power supply circuit B36 of the power supply circuit board 55, and is applied to the integrated control device MC.

When the integrated control device MC is started, it first performs an initial self-diagnosis before the start of the heating operation, and confirms that no abnormality has occurred. In addition, the integrated display unit 30 is activated to display the initial information.

In this state, when the user opens the door 114 of the heating chamber 113 in order to use the microwave heating device 120, the door open / close detection mechanism 131 transmits a signal indicating the opening of the door 114 to the control device 105. Therefore, the control device 105 transmits a signal indicating the opening of the door 114 to the integrated control device MC. The integrated control device MC presumes that the user performs microwave heating cooking, displays necessary information for starting microwave heating on the integrated display unit 30, and prompts an input for starting heating.

When the user puts food or the like into the heating chamber 113 and closes the door 114, the door open / close detection mechanism 131 again transmits a detection signal indicating that the door 114 is closed to the integrated control device MC via the control device 105. .. Therefore, when a command to start heating is issued from the input operation unit 40 in this state, the right input control device 23 detects the presence / absence of touch input of the input key for microwave heating. Therefore, a signal indicating a heating start command is transmitted from the right input control device 23 to the integrated control device MC.

The right side input control device 23 also detects the input of the central operation unit 40M. Therefore, the selection value signal IP4 corresponding to the touch information on the operation panel 311 of the integrated display unit 30 is transmitted to the display unit drive circuit 63.

Here, referring to FIG. 43 again, the operation of performing cooking using the oven heating source 188 and the microwave heating source 189 will be described.
FIG. 43 shows a scene in which the user selects the control menu "oven" using the oven heating source 188.

In FIG. 43, three fingertip FGs of the user are drawn at the same time, but it does not indicate that the three fingertip FGs are operating the touch gesture at the same time. It is shown that the touch gesture operation is sequentially performed three times from the first area 30L on the left side to the right side.

When the user performs a touch gesture operation (hereinafter abbreviated as "touch operation") in the first area 30L, the operation determination unit 313 of the touch gesture determination device 302 is the first area constituting a part of the operation panel unit 311. Receives touch information IP1 from 30L and input information IP2 corresponding to this touch information.

With the control menu "oven" displayed in the first area 30L, in the first area 30L, the user touches the first area 30L with the fingertip FG while moving to the front FR or the rear BK (constant speed). When it is moved (within a range), the gesture mode determination unit 314 recognizes that it is a normal (specific) touch gesture operation, and touch information is generated.

Then, in the case of touch information indicating that the front FR has been operated, the operation determination unit 313 changes the display of the first area 30L via the display unit drive circuit 63. Then, the next candidate "grill" or "warm" can be displayed in the first area 30L.

Similarly, the target temperature can be selected in the second area 30M. In FIG. 43, "180 ° C." is displayed as the default value, but it can be changed to the target temperature information 30T1 of "185 ° C." displayed on the candidate display unit 30Y. Further, when the rear BK is touch-operated, the target temperature information 30T2 of "175 ° C." can be displayed in the central portion.

Similarly, in the third area 30R as well, if the touch gesture operation is recognized by the gesture mode determination unit 314, touch information is generated each time, and the display information of the third area 30R can be changed.

In the second embodiment, the touch gesture operation as recognized by the gesture mode determination unit 314 is set so that the movement direction after touching is either the front FR or the rear BK. , The display cannot be switched by touch gesture operations such as "pinch in" and "pinch out" as described above. The reference parameter storage unit 317, which will be described later, stores parameters limited to the slider mode among user gestures. Therefore, the display cannot be switched in a state where it cannot be determined from the slider mode. For example, the above-mentioned "pinch-in" or "pinch-out" touch gesture operation does not match the parameters based on the combination of the movement amount, the touch gesture operation speed, the touch time, and the like in a predetermined time. ..

FIG. 45 shows a modified example of the second embodiment of FIGS. 40 to 44, and is a plan view of a front portion for explaining the arrangement of the central operation unit 40M and various display units.

In the reference parameter storage unit 317 in the modified example of FIG. 45, at least the parameters of the slider mode among the gestures of the user are stored. The slider mode is specified in two directions, the front-back direction and the direction perpendicular to the front-back direction (the range of ± 30 degrees to the right direction). One example of the parameter is a parameter determined based on any one or a combination of two or more of the movement amount of the touch gesture operation in a predetermined time, the speed of the touch gesture operation, or the touch time.

For example, if the touch is continued for a certain period of time (for example, 3 seconds or 5 seconds) while being touched on the name of the control menu "RG manual" shown in FIG. 45, another situation is observed. Explanation of the control menu touched in the display area, for example, the second area 30M or the third area 30R, reference information for determining the control conditions of each control menu, and cooking precautions corresponding to the control menu (pots, etc.) (Including cooking utensils) and the like may be displayed in characters, figures, etc. in the form of an additional screen 30AD having a small area. FIG. 45 is an example in which additional information 30Q is displayed in characters for a container for containing food.

Further, the voice guide by the voice synthesizer 95 may provide advice to supplement the user's operation. In order to make such a change, it is necessary to expand or change the gesture determination data of the gesture mode determination unit 314 and the parameter information of the reference parameter storage unit 317.

In FIG. 45, the fingertip FG is moved to the right while being touched on the first area 30L. However, when the fingertip FG is moved to the right in this way, the gesture mode determination unit 314 is one. Determine to return to the previous display content. Therefore, the additional screen 30AD shown in FIG. 45 is erased.

The gesture mode determination unit 314 and the reference parameter storage unit 317 do not detect the user's strict right-hand touch gesture, but detect the locus of the fingertip FG with a certain detection range. Therefore, even if the fingertip is moved slightly diagonally, the gesture mode determination unit 314 can determine that the cancellation command is for the additional screen 30AD. In addition, instead of erasing the additional screen 30AD with the touch gesture of the right method in this way, it is changed to a method of automatically erasing from the display in a certain time or a method of immediately erasing when the additional screen 30D is touched again. You may.

FIG. 46 is an explanatory diagram 1 showing the display operation of the integrated display unit 30 of the cooking device of FIG. 40.
As is clear from FIG. 46, when the integrated control device MC is started, the initial self-diagnosis before the start of the heating operation is first performed to confirm that no abnormality has occurred. Further, the integrated display unit 30 is activated, and the standby common information 30N is displayed as the initial information.

The integrated control device MC has the microwave heating source 189 and the microwave heating source 189 on the display screen 30D before the input operation unit 40 selects either the microwave heating source 9 or the oven heating source 188. After displaying the standby common information of the oven heating source 188 and selecting either the microwave heating source 189 or the oven heating source 188, the first area 30L, the second area 30M, and the like. The "control menu" and "control conditions" are displayed by dividing into the third area 30R.

Hereinafter, the operations of the input operation unit 40 and the integrated display unit 30 will be described with reference to FIG. 46.
Since the integrated display unit 30 is not activated in the state where the main power switch 97 is turned off, no information is displayed.
In the state where the main power switch 97 is turned on, the integrated control device MC displays the display screen 1 of FIG. 46 on the integrated display unit 30 after performing a self-diagnosis such as the presence or absence of an abnormality as described above.

The display screen 1 of FIG. 46 is the same as the display screen 1 described with reference to FIG. 32 of the first embodiment.
30B is two-dimensional information (two-dimensional code) for guiding to a dedicated recipe posting site via the Internet. 30C is a sentence explaining the meaning of the two-dimensional code. The two-dimensional information 30C and the display text are one type of "standby common information" 30N.

After the display screen 1 is displayed, the display screen 2A or 2B may be automatically displayed. In addition, the display screens 2C to 2E may be displayed. On the display screen 2A, "Caution for sudden boiling" is one of the caution displays.

One of the features of the second embodiment is that in addition to the display screens 2A and 2B described in the first embodiment, three display screens 2C to 2E can be displayed.

As described in the first embodiment, the control menu for cooking by combining microwave heating and oven heating using the heating chamber 113 was called "range grill cooking". Also in the second embodiment, in the microwave oven cooking, a pattern in which microwave heating is performed first, the food is heated to some extent, and then the food is heated by the upper heater 163A and the lower heater 163B, and the pattern in which the heating is performed in the reverse order. , And there are three types of patterns in which microwave heating and heater heating are performed at the same time.

Generally, it is common practice to put the food to be cooked in a heat-resistant plastic container or tableware and perform microwave heating. However, if the upper heater 163A or the lower heater 163B is then heated in this state, the above There is a risk that the container, etc., will be burnt out due to high heat.

Therefore, on the display screen 2C, in the "range grill (RG)" of the control menu, a caution display sentence 30E is displayed in which a plastic container is placed inside the heating chamber 113 to warn against heating. That is, when executing the control menu called "range grill", this cautionary statement 30E is a kind of "standby common information" 30N referred to in the present invention.

The display screen 2D relates to a case where microwaves are introduced into the heating chamber 113 to cook by heating the control menu of "warming", and the temperature of the grill (heating chamber 113) is high and the "warming" is performed. The control menu is an example of notifying that it cannot be selected. 30E is a cautionary statement 30E indicating that "range automatic" cannot be used.

In the "warm" (automatic range) control menu, the non-contact (infrared) temperature measuring unit 158 detects the temperature of the object to be cooked in the heating chamber 113 and the wall temperature of the heating chamber 113, and when the target temperature is reached. Automatically stops the oscillation of microwaves. Therefore, when the heat from the previous cooking remains and the temperature is high from the beginning, the integrated control device MC prohibits the automatic microwave heating. Therefore, as shown in the display screen 2D of FIG. 46, the user is notified to select the control menu of "range manual". Since the "microwave oven manual" is performed by setting the microwave heating time, even if the temperature of the object to be cooked in the heating chamber 113 or the wall surface temperature of the heating chamber 113 is high, cooking can be performed without any problem. The display text 30E of the display screen 3D is also a kind of "standby common information" 30N referred to in the present invention.

On the display screen 2E, 30E is a caution display warning that the top plate 15 is at a high temperature and is not inadvertently touched. When the object to be heated N such as a metal pot or a metal plate is placed on the top plate 15 and induced to be heated, the temperature of the object to be heated N is received and the temperature of the top plate 15 also becomes high. Therefore, as in the first embodiment, the high temperature notification unit 69 is provided at a position immediately behind the heating source display unit 68, but in addition to the high temperature notification unit 69, the integrated display unit 30 also provides the same high temperature notification unit. This display screen 2E is used when performing the above. The display statement 30E indicating that the top plate 15 of the display screen 2E is hot is also one of the “standby common information” 30N according to the present invention.

The display screens 2C to 2E do not have to be displayed when the main power switch 97 is always turned on.
For example, the following patterns are used.
(1) When the top plate 15 has a high temperature, the display screen 1 and the display screen 2E are alternately displayed at intervals of several seconds.
(2) When the heating chamber 113 has a high temperature, the display screen 1 and the display screen 2D are alternately displayed at intervals of several seconds. Alternatively, the display screen 1 and the display screen 2B are alternately displayed at intervals of several seconds.
(3) If there is actual (history) data cooked in the control menu of the "range grill" during the previous cooking or the past several cookings before turning on the main power switch 97, display screen 1 is displayed. The screen 2C is displayed alternately at intervals of several seconds. The integrated control device MC automatically accumulates the number of times the "control menu" is executed at the time of one cooking, and stores it in the storage unit MM as the past cooking history. Therefore, after the main power switch 97 is turned on, the actual results of the range grill cooking can be grasped by referring to the above-mentioned cooking history.

When the top plate 15 is at a high temperature and the heating chamber 113 is also at a high temperature, the display screen 1 is first displayed for a few seconds, and then the display screen 2D and the display screen 2E are displayed. It may be displayed alternately at intervals of several seconds. The contents of the "standby common information" 30N of each of the display screens 2A to 2E as described above may be notified by voice by the voice synthesizer 95.

As is clear from the display screens 1 to 2E of FIG. 46, these displays are performed by using the entire display screen 30D. That is, instead of partially displaying in any of the first area 30L to the third area 30R described above, the three areas 30L to the third area 30R cannot be identified in order to secure the widest possible display area. In this way, the integrated display is performed so that the user can see that the integrated display unit 30 is displayed as a whole.

The integrated control device MC sends a drive command to the control device 105 that controls the microwave heating operation, closes the relay 182, drives the inverter circuit 121A, and starts microwave heating. At the same time, an operation command signal is issued to the drive circuits 177A and 177B of the third cooling fan 128 and the fourth cooling fan 129, and the operation of the two cooling fans 128 and 129 is started. Further, although not shown in FIG. 40, the antenna driving motor 126 is driven to rotate the antenna 125. As a result, microwaves are introduced into the heating chamber 113 to cook the food.

As is clear from the above description, the first cooling fan 60 and the second cooling fan 61 of the upper unit 100 are not operated at all during the period of microwave cooking. Therefore, the power consumption of the entire cooking device 1 can be suppressed to a low level.

The right operation unit 40R constituting the input operation unit 40 and the touch type input key unit in the left operation unit 40L are provided with electrodes for detecting a change in capacitance corresponding to each touch key area. It requires a large number of components such as such electrodes and LEDs (light emitting diodes) for illuminating each touch key portion with light. Therefore, although not shown in FIG. 40, the components constituting the touch-type input key unit are mounted on the central operation board 32 and the left operation board 38. The components of the input key 98 of the power switch 97 are also mounted on the central operation board 32.

If the user touches the input key 43MS while the desired control menu is displayed in the first area 30L to the third area 30R, the conditions displayed in the first area 30L to the third area 30R can be changed. , The right side input control device 23 recognizes the confirmation information (confirmation control menu, confirmation value) and transmits the confirmation information to the integrated control device MC. After that, control is executed based on this definite information.

The cooking device 1 of the second embodiment is
An upper unit 100 having an induction heating source 9 for heating an object to be heated and supported by kitchen furniture, and an upper unit 100.
A lower unit 200 attached to the upper unit 100 and having a built-in heating chamber 113 is provided.
In the lower unit 200, a microwave heating device 120 for supplying microwaves to the heating chamber 113 and an oven heating device 140 for heating the heating chamber are arranged.
The upper unit includes a control device 90 that controls the induction heating source 17, a control device 105 that controls both the microwave heating device 120 and the oven heating device 140, and these two control devices (slave microcomputers) 90. , 105 is equipped with a control device MC (master microcomputer) MC for integrated control.
The upper unit 100 includes a filter circuit board 55 that receives power from the commercial power supply 99, and a power supply circuit 55 (34, 36) that converts the power from the filter circuit board 55 into a specified power supply voltage.
The control device 105, the control device 90, and the integrated control device MC are supplied with low voltage power generated by the power supply circuit 55 (34, 36) as a power source.
The inverter circuit 81 of the induction heating source 17, the microwave generation source 122 of the microwave heating device 120, the upper heater 163A and the lower heater 163B of the oven heating device 140 are the filter circuit 54 and the power supply circuit 55 ( The configuration is such that the electric power (200V power supply) distributed from between 34 and 36) is applied.

With this configuration, the overall power supply configuration of the cooking cooker 1 is simplified, and reliable operation can be expected by suppressing the propagation of unnecessary noise.

The cooking device 1 of the second embodiment has been invented in the following form.
That is, the main body 110 having a built-in microwave heating source 189 and
An oven heating source 188 that heats the inside of the heating chamber 113,
The input operation unit 40 that accepts user operations and
An integrated display unit 30 shared by the microwave heating source 189 and the oven heating source 188 and having a display screen,
A control unit (integrated control device MC, control device 105) for controlling the microwave heating source 189 and the oven heating source 188 is provided.
The input operation unit 40 includes an input device (touch panel input device 301, touch gesture determination device 302) for selecting a specific control menu from the control menu group, the microwave heating source, and the oven heating source. Has a start key that can command the heating operation of
The control unit combines one control menu with one of "control condition" information such as heating intensity or target temperature and heating time applied to the control menu according to the user's operation on the input device. The information to be shown is displayed on the display screen.
The control unit has a configuration for displaying (on the candidate display unit 30Y) information on "control conditions" that can be selected next, which is different from the combination of the control menu and one of the "control conditions" information. rice field.

According to this configuration, both microwave heating and oven heating can be performed in one cooking device, and the cooking device is highly convenient and can be used for a wide range of cooking.

Moreover, in the display screen 30D of the integrated display unit 30 shared by the microwave heating source 189 and the oven heating source 188, the specific control menu (for example, "for example," is selected in the selection of one control menu when performing microwave heating. Before selecting "warm") to start cooking, separate the control menu and one or more "control condition" information (combination of microwave heating time and grill cooking time information), then Control condition information that can be preferentially selected (for example, in "RG manual" in FIG. 42, the combination of "50 seconds" and "1 minute 10 seconds" is also displayed for the time "1 minute"), so that it depends on the user. It can help to easily confirm the control menu. Therefore, even if it is a composite type cooking device, it can be a cooking device that is easy to use.

Further, as described with reference to FIG. 44, a touch panel input device 301 and a touch gesture determination device 302 are provided as input devices, and the display screen of the integrated display unit 30 is input by a user's touch operation. , The control menu can be input without forming hardware (structure) such as touch keys and buttons in the input operation unit 40. Intuitive operation is possible without considering the functions of multiple input keys. For this reason, the user's feeling of operational burden is reduced, another structure is placed in the space occupied by the hardware (structure), or the display screen of the integrated display unit is enlarged according to the increase in the space. In the end, it is possible to increase the benefits of the user.

In the second embodiment, when the integrated control device MC is supplied with power, the integrated control device MC first displays the standby common information 30N on the display screen 30D, and the display state is continued for several seconds to 10 seconds. The input functions of the central operation unit 40M, the right operation unit 40R, and the left operation unit 40L were enabled. That is, immediately after the main power switch 97 is turned on, the induction heating source 9, the microwave heating source 189, and the oven heating source 188 cannot be selected.

On the other hand, from the moment when the standby common information 30N is displayed (for example, see the display screen 1 in FIG. 46), the input functions of the central operation unit 40M, the right operation unit 40R, and the left operation unit 40L. You may change to the method to enable. According to this, a user who has a good understanding of how to use the food, such as a proficient user, can finish the selection of the heating source and proceed to the step of starting cooking at an early stage before the display of the common information during standby is finished.

As described above, according to the configuration of the second embodiment, three types of heating modes of induction heating, microwave heating and oven heating can be carried out in one cooking device, and it is convenient to support a wide range of cooking. It becomes an expensive cooker.
Moreover, on the display screen 30D of the integrated display unit 30 shared by the microwave heating source 189 and the oven heating source 188, the user is made to display useful standby common information 30N before the start of the heating operation. Therefore, even a composite type cooking cooker that can use three types of heating forms can be an easy-to-use cooking cooker.

Other embodiments.
In the case of a user (user) who does not need both the upper unit 100 and the lower unit 200 at the same time as shown in the first and second embodiments, the upper unit 100 and the lower unit 200 are sold or installed in the kitchen furniture 2. The work will be separate. The lower unit 200 is set as an optional item, for example. In such a case, for example, if the packing form for selling the upper unit 100 and the lower unit 200 as a set and the packing form for selling only the upper unit 100 are set separately, the convenience at the time of sale is impaired. Never.

In carrying out the present invention, as shown in the first and second embodiments, it is not essential that the upper unit 100 and the lower unit 200 are configured in separate housings. Therefore, the upper unit 100 and the lower unit 200 may be configured by one housing (main body case) from the beginning.

As the induction heating circuit, various drive methods such as a half-bridge circuit and a full-bridge circuit may be adopted depending on the form and number of the IH coils 17L and 17R. For example, the full bridge circuit is proposed in Japanese Patent No. 6130411 and Japanese Patent No. 6173623.
Further, the IH coil is arranged not only in a donut-shaped form but also in an annular main heating coil and close to both sides of the main heating coil, as shown in, for example, Japanese Patent No. 55338546. An induction heating unit including a flat first sub-heating coil and a second sub-heating coil having a width dimension smaller than the radius of the main heating coil may be used.

Further, in the first embodiment, when the induction heating is started, the induction heating operation is started under the default conditions (thermal power value and thermal power level) without setting the thermal power, and then the heating start in which the user decides the desired thermal power. The operation method was adopted. However, other methods may be used. For example, after turning on the main power, it is necessary to determine the target induction heating source and the thermal power value (watt) and thermal power level (one of the stages such as thermal power "large" to "small") and issue a start command. A certain operation method may be adopted, and even such a method does not affect the essential effect of the present invention.

In the above description, the present invention has been described in the case of a cooking cooker provided with two induction heating portions as a typical example of the heating cooker 1, but for example, induction heating portions are provided at a total of three places on the left, right, and center. You may change to a cooking device.

In the second embodiment, neither the first cooling fan 60 nor the second cooling fan 61 of the upper unit 100 was operated during the period of microwave cooking, but the first cooling fan 60 and the first cooling fan 60 were not operated. 2 Both or one of the cooling fans 61 may be operated. When at least one of the first cooling fan 60 and the second cooling fan 61 is operated, external air is continuously introduced into the internal space of the upper unit 100, and there is an advantage that the temperature of the upper unit 100 can be suppressed to a low level.

Of each of the processes described in the embodiments, all or part of the processes described as being automatically performed can also be performed manually. It is also possible to automatically perform all or part of the processing described as being performed manually by a known method.

Further, each component of each circuit, component, and device shown in the figure is a functional concept and does not necessarily have to be physically configured as shown in the figure. Further, in particular, the integrated control device MC, the microwave heating control unit 130, the heating chamber control unit 159, and the display unit drive circuit 63 described with reference to FIG. 15 can disperse and integrate the functions of each of these devices / circuits, and are concrete. The form is not limited to the one shown in the figure, and all or a part thereof can be functionally or physically distributed / integrated in any unit according to the function, the operating condition, and the like.

For example, a part of the data or the program of the storage device MM and the storage device 90R shown in FIG. 15 may be held in an external recording medium (storage server or the like) without being held by the cooking cooker 1. In this case, the cooking cooker 1 acquires necessary data and program information by accessing an external recording medium (storage server).

Further, in particular, the operation programs of the integrated control device MC, the microwave heating control unit 130, the heating chamber control unit 159, and the display unit drive circuit 63 described with reference to FIG. If desired, it may be updated with an improved one as appropriate. In this case, for example, the patch may be obtained through the wireless communication unit 49.
