Reference form 1.
1 to 15 show an induction heating cooker according to Reference Form 1. In the following description, it is simply referred to as "cooking cooker".
In FIGS. 1 to 15, the heating cooker 1 of the present reference embodiment is, for example, an induction heating cooker having a commercial power supply of 200 V, which is incorporated in a kitchen furniture (also referred to as a “system kitchen”) 2 with a sink. 2A is an installation port formed in the kitchen furniture 2. The cooking device 1 is supported by being placed on the mouth edge portion of the installation port 2A. As shown in FIG. 3, 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 in the reference form 1. Reference numeral 2B is an opening formed at a predetermined position of the kitchen furniture 2, and this opening is for exposing the front surface (the cover 30 side, which will be described later) to the front when the cooking cooker 1 is incorporated. The sizes of the opening 2B and the installation port 2A are formed to predetermined dimensions according to the kitchen standard.

The usual method of incorporating the cooker 1 into the kitchen furniture 2 is as shown in FIG. FIG. 13 is a schematic view showing an intermediate stage of the work of incorporating into the kitchen furniture 2. As shown in this figure, when the main body case 3 is inserted into the installation port 2A while the front side (front side) of the main body case 3 is tilted downward, and then the rear side of the main body case 3 is lowered. , The cooker 1 is placed on the peripheral edge of the kitchen furniture 2 installation port 2A. Finally, in order to fix the state, tighten the screws and fix it on the peripheral edge of the main body case 3. The installation is completed by moving (rotating) the metal fitting (not shown) and pressing the fixing metal fitting strongly against the kitchen furniture 2. Since such an installation method has already been widely adopted, the detailed structure will not be described.

The heating cooker 1 includes a box-shaped main body case 3 constituting the outer shell, a metal frame-shaped outer frame (not shown) fixed to the upper portion thereof, and substantially the entire upper surface of the outer frame. It is composed of a top plate 4 made of heat-resistant tempered glass, which is superposed on the upper surface of the top plate 4 so as to cover it. Since the entire lower surface of the top plate 4 is covered with a painted surface that does not allow visible light to pass through, functional parts below the top plate 4, for example, the right heating coil 8R, which will be described later, cannot be visually recognized from above the top plate 4. It has become.

In FIG. 5, the main body case 3 has a body portion 3U formed by bending a thin metal plate with a press device into a U-shaped cross section, and a front plate 3F bonded to the front side of the body portion by welding or screwing. And the rear face plate 3H, which is joined to the rear side of the body by welding or screwing, constitutes a main body case in which the entire upper surface is open. The rear surface plate 3H may be formed by bending one metal thin plate, but is usually formed by joining two or three thin plates by welding or screwing. As will be described later, when the cooking device 1 is inserted into the installation port 2A (see FIG. 13), the 3J has an inclination formed so that the rear surface plate 3H does not hit the kitchen furniture 2 (on the rear surface plate 3H). It is a face part. Therefore, in the bottom surface portion 3B of the main body case 3, the range in which the storage chamber 21 described later can be installed is a range of a predetermined length of 3K with respect to the front insertion port 22 as shown in FIG. The bottom surface portion 3B is a part of the body portion 3U.

In FIG. 10, BS1 is a gap formed between the rear surface plate 3H and the back plate 2U of the kitchen furniture 2. The first blower BM1, which will be described later, may suck all or part of the cooling air from this void.
In FIG. 10, BS2 is a gap formed between the back surface of the storage chamber 21, which will be described later, and the rear surface plate 3H.

In FIG. 10, there is a gap of about 2 cm to several millimeters (mm) between the lower surface of the cover 30 described later and the upper surface of the decorative plate (also referred to as “decorative frame”) 44 in order to allow the cover 30 to move. The GPU is formed. Since this gap GPU also communicates with the gap BS1, the first blower BM1 may introduce air from the gap GPU on the front side. When the air is taken in by using this gap, it is possible to omit installing the intake port on the upper surface of the main body case 3, or the opening area of the intake port can be reduced to make it inconspicuous. Can be expected to improve. In addition, in FIG. 10, the GPT allows the cover 30 to move between the top surface of the handle portion 31A at the top of the cover 30 described later and the lower surface of the opening 2B on the front surface of the kitchen furniture 2. It is a void of about 2 cm to several millimeters (mm) formed.

In FIG. 10, reference numeral 5 denotes a rear frame plate fixed to the rear portion of the outer frame, and an intake port (not shown) and an exhaust port 6 (see FIGS. 4 and 10) are formed, respectively. Reference numeral 7A is an intake cover placed on the intake port, and a plurality of narrow through holes parallel to each other are formed in order to ensure ventilation. Reference numeral 7B is an exhaust cover placed on the exhaust port 6, and a plurality of narrow through holes parallel to each other are formed in order to ensure air permeability. As shown by the broken line in FIG. 4, the width dimension of the exhaust port 6 is limited to only a part of the exhaust cover 7B and has a corresponding length. Further, the intake port (not shown) is also formed so as to be limited to a range corresponding to only a part of the intake cover 7A, and is formed only directly above the first blower BM1 described later.

In FIGS. 5 and 6, 8R is a right side (induction) heating coil (heating source) installed below one induction heating unit (also referred to as a “heating port”) on the top plate 4. It has a donut-like shape. The maximum thermal power of the right heating coil 8R is 3000 W. The maximum external dimension (diameter) RR is 168 mm.

Reference numeral 8L is a left side (induction) heating coil installed below the one induction heating portion on the top plate 4, and has a donut-shaped shape. The maximum thermal power of the left side heating coil 8L is 3000W. The maximum external dimension (diameter) RL is 168 mm.

Reference numeral 8M is a central (induction) heating coil similarly installed below one induction heating portion on the top plate 4, and has a donut-shaped shape. When these induction heating coils are generically referred to, they may be referred to as "heating coil, heating means", and in that case, the reference numeral 8 is used. Further, when it is not necessary to specify 8R, 8L, and 8M in particular, the terms "right side" and "left side" may be omitted. The maximum thermal power of the central heating coil 8M is 1500W. The maximum external dimension (diameter) RL is 130 mm.

All three heating coils 8M, 8L, and 8R are installed at the same horizontal position so that the facing distance from the lower surface on the top plate 4 is several mm or less.

Next, one induction heating unit (heating port) will be described with reference to FIG. 7.
It has the left side heating coil 8L, a coil base 32, a ferrite 33, and a magnetic shield ring 34.
The coil base 32 integrally holds one or a plurality of heating coils provided for one heating port. Specifically, the coil base 32 has a circular window 32A in the center thereof, and has about 6 to 10 arms 32W radially around the window. Furthermore, a large through hole is formed around this arm. That is, the coil base 32 itself has a structure that is highly breathable in the vertical direction. Such a coil base 32 is proposed, for example, in (Japan) Utility Model Registration No. 3018751.

The coil base 32 is integrally made of heat-resistant and electrically insulating plastic that does not deform even at about 350 ° C. Reference numeral 34 denotes a magnetic shield ring, which goes around the outer circumference of the coil base 32 at intervals. That is, it is provided so as to surround the left side heating coil 8L. The magnetic shield ring 34 surrounds the outer periphery of the left side heating coil 8L, so that when a high frequency current flows through the coil, a high frequency magnetic field that does not reach the upper objects to be heated 9, 10, 11 and the like is generated by the left side heating coil 8L. It suppresses leakage to the outside of the main body case 3 and the outside of the main body case 3.

The magnetic shield ring 34 is formed by electrically connecting both ends of a strip-shaped conductive member so as to be electrically conductive. For example, a member long in one direction is bent in a circular shape, and both ends thereof are integrally pressed or welded to form an electrically conductive member. Therefore, when a high-frequency magnetic field is generated by the left heating coil 8L, an eddy current flows through the magnetic shield ring 34 and is converted into heat by the internal resistance of the magnetic shield ring 34, thereby suppressing the leakage flux.

In FIG. 7, the coil base 32 is provided with a ferrite 33 below the left heating coil 8L. The ferrite 33 has the purpose of preventing the magnetic field generated by the left side heating coil 8L from flowing below the left side heating coil 8L13 and concentrating the magnetic field on the objects to be heated 10, 11, and the like. In this reference embodiment, as an installation example, a case is shown in which the left side heating coil 8L is installed so as to be approximately orthogonal to the winding, that is, the left side heating coil 8L is installed radially from the center thereof.

An elastic body (not shown) such as a compression spring is provided as an elastic support means between the lower surface of the coil base 32 and the upper surface of the ventilation duct 74. The elastic body is fixed to a support portion formed on the upper surface of the ventilation duct 74. As a result, the coil base 32 is supported by the ventilation duct 74 via the elastic support means, so that the coil base 32 is supported in a form of being pressed against the back surface (lower surface) of the top plate 4.

Reference numeral 35 denotes a space holding member fixed to, for example, eight places at regular intervals on the upper surface of the outermost annular frame of the coil base 32. Since the space holding member 35 is pressed against the lower surface of the top plate 4, the coil base 32 and the left side heating coil 8L are held at a predetermined distance from the lower surface of the top plate 4. As a result, the distance between the objects to be heated 10, 11 and the like and the upper surface portion of the left side heating coil 8L is appropriately maintained, and induction heating can be efficiently performed.

Further, the interval holding member 35 appropriately maintains the interval between the upper surface of the left side heating coil 8L and the lower surface of the top plate 4, and enables the cooling air for cooling the left side heating coil 8L to pass between them. A part of the coil base 32 may be used as the material of the space holding member 35, but if it is formed of an elastic material such as rubber, which is a member different from the coil base 32, the space holding member 35 and the top plate 4 are formed. This is preferable because the degree of adhesion of the rubber is improved.

The central portion of the coil base 32 has a portion that does not hold the left side heating coil 8L and a portion that is not provided with the ferrite 33, and the window 32A described above is formed in the center of this portion. Cooling air can pass through this window from below. Further, the window 32A is provided with an infrared temperature sensor 36 that receives infrared rays radiated from the objects to be heated 9, 10, 11 and the like and detects the temperature of the objects to be heated in a non-contact manner. The temperature detection information of the infrared temperature sensor 36 is sent to the temperature detection circuit 63, which will be described later.

The position of the upper wall surface 21T of the storage chamber 21 is structured so as to maintain a predetermined interval H2 in order to reduce the magnetic influence from the left heating coil 8L. This will be described in detail later.

The right side heating coil 8R and the central heating coil 8M are also provided with the coil base 32, the ferrite 33, the magnetic shield ring 34, the interval holding member 35, and the infrared temperature sensor 36, respectively.

In FIG. 1, 8LS is a circular mark indicating a reference position where induction heating can be performed by the left heating coil 8L, and is formed by printing on the upper surface of the top plate 4. The 8MS is a circular mark indicating a reference position where induction heating can be performed by the central heating coil 8M, and is formed by printing on the upper surface of the top plate 4. In addition to this, although not shown, a circular mark indicating a position where induction heating can be performed by the right heating coil 8R is also provided on the upper surface of the top plate 4 by printing.

The position and size (diameter dimension) of the circular mark 8LS are determined according to the outer diameter dimension 8D (see FIG. 5) of the left heating coil 8L. The same applies to other induction heating coils. Although the positions of the three heating coils 8 are indicated by circles in FIG. 4, since the top plate 4 which is opaque is actually on the top as described above, these heating coils 8 are used by the user. Cannot be seen visually. Further, one or two of the three heating coils 8 may be replaced with a radiant electric heat source such as a radiant heater or an infrared heater.

In FIGS. 1, 2, and 4, 9 is a cooking utensil having an elliptical or rectangular planar shape (first cooking utensil), and as shown in detail in FIG. 11, a magnetic metal such as stainless steel or iron. It is composed of a dish portion 9A made of wood and a transparent heat-resistant glass lid 9B that covers the upper part of the dish portion. 9C is a knob for the user to carry the lid 9B. Further, 9D is a handle integrally molded at both ends of the dish portion 9A. The rectangular shape shown by the two-dot chain line in FIG. 4 indicates the range of the bottom surface of the dish portion 9A, and does not indicate the outer shape of the dish portion 9A. In other words, the minor axis dimension of the bottom surface of the dish portion 9A is as shown by reference numeral SS in FIG. The major axis dimension of the bottom surface of the dish portion 9A is as shown by reference numeral LS in FIG. The first cookware (heated object) 9 is manufactured exclusively for the cooker 1 (by the manufacturer of the cooker).

Since the external shape of the cooking utensil 9 has a simple structure in which handles 9D are integrally provided at both ends of the dish portion 9A, when the cooking utensil 9 is stored in the storage chamber 21 from the insertion port 22 described later, the insertion thereof is reversed. Even when taking out through the mouth 22, the user can move the dish portion 9A and the lid 9B together, which is convenient.

If the handle 9D is provided at the uppermost portion of the dish portion 9A as shown in the figure, the distance from the upper surface of the top plate 4 can be increased. That is, since it is far from the induction heating coil 8L below the top plate 4, it is possible to suppress the induction heating of the handle 9D. It is desirable that the handle 9D is located at a position 5 cm or more away from the bottom surface of the dish portion 9A (the surface close to the upper surface of the top plate 4), but if it is separated too much, the maximum height dimension of the dish portion 9A becomes larger. The height dimension of the storage chamber 21 and the insertion slot 22 must be increased.

In FIG. 4, reference numeral 10 denotes a cooking utensil having a circular planar shape (second cooking utensil), which is a commercially available large-diameter pot made of metal (at least the bottom surface thereof is made of magnetic metal). Reference numeral 11 denotes a cooking utensil having a circular planar shape (third cooking utensil), which is a commercially available small-diameter pot made of metal (at least the bottom surface thereof is made of magnetic metal).

As is clear from FIG. 4, the minor axis dimension SS of the first cooking utensil 9 is equal to or about 2 to 3 cm from the outer diameter dimension of the left side heating coil 8L (see FIG. 5 for the diameter 8D). big. Further, the second cooking utensil 10 suitable for induction heating on the right side heating coil 8R has a bottom diameter dimension equal to or about 3 to 4 cm from the outer diameter dimension of the right side heating coil 8R. big. Further, the third cooking utensil 11 suitable for induction heating on the central heating coil 8M has a bottom diameter dimension equal to or about 2 to 3 cm from the outer diameter dimension of the central heating coil 8M. big.

As is clear from FIG. 4, on the upper surface of the top plate 4, a wide area from the front of the intake cover 7A and the exhaust cover 7B to the rear end of the operation unit 12, which will be described later, is cooked used for induction cooking. Area 13. The meaning of this "heating area" 13 does not mean that the entire area can be induced and heated by the heating coil 8, and the first to third cooking utensils 9, 10, 11 and the like are temporarily placed when they are not cooked. Or can be placed for induction heating. HA indicates the length in the front-rear direction of the cooking area 13, that is, the depth dimension.

As is clear from FIG. 4, the center portions of the right side heating coil 8R and the left side heating coil 8L are located directly below the front-back direction center line CL2 of the cooking area 13.
On the other hand, the central portion of the central heating coil 8M is located directly below the left-right center line CL1 of the cooking area 13.

In FIG. 4, reference numeral 12 denotes an operation unit formed on the front upper surface of the top plate 4, and as described below, input is made by utilizing a change in capacitance when the user lightly touches the top plate 4 with a finger or the like. Various input keys that can be used are arranged in a straight line in the horizontal direction.
The operation unit 12 includes a right operation unit 12R, a center operation unit 12M, and a left operation unit 12L.

In FIG. 4, reference numeral 14 denotes an operation button or an operation key (touch input type) of the main power switch 61 that can supply and shut off the commercial power supply 60 (see FIG. 13) to the control device 56 described later.

Three touch-type input keys 15 are arranged on the right operation unit 12R. These input keys 15 are assigned one or more input functions. For example, the thermal power (power consumption) at the time of induction heating, the induction heating time, the induction heating pattern, and the like. The right operation unit 12R is for commanding the start and stop of the operation of the right heating coil 8R and other energization conditions (time, thermal power, etc.).

In FIG. 4, reference numeral 16 denotes three touch-type input keys arranged in the central operation unit 12M. The central operation unit 12M is for commanding the start and stop of the operation of the central heating coil 8M and other energization conditions (time, thermal power, etc.).

In FIG. 4, reference numeral 17 denotes three touch-type input keys arranged on the left operation unit 12L. The left operation unit 12L is for commanding the start and stop of the operation of the left side heating coil 8L and other energization conditions (time, thermal power, etc.).

In FIG. 4, reference numeral 18 denotes a touch-type input key for an Internet connection command for instructing the control device 56 to perform wireless communication. Reference numeral 19 is a touch-type input key for a confirmation command for requesting the control device 56 for the existence result of the first cooking utensil 9. The operation of these two input keys 18 and 19 will be described in detail later.

In FIG. 4, reference numeral 20 denotes a rectangular display screen arranged directly below the transparent display window provided in the front center portion of the top plate 4, for example, a liquid crystal display screen. On this display screen, the operation result of the operation unit 12 is displayed by characters, symbols, or the like, or the operation status of various functional parts detected by the control device 56 is displayed. After the operation button or operation key 14 of the main power switch 61 is turned on, the display operation of this display screen is started by the command of the control device 56.

Next, the storage chamber 21, which is one of the feature points of the present invention, will be described. As shown in FIGS. 1, 6, 8 and 10, the storage chamber 21 is partitioned in the main body case 3. Here, the term "compartment formation" means that in the lower space 71 described later, the space between the storage chamber 21 and the second space 71B is a physical object (meaning a plate, a wall, etc., such as metal or plastic). It is a state where air flow is not allowed by design because it is partitioned by (formed).
A second partition wall 73 in the vertical direction, which will be described later, is installed in the lower space 71, and the second partition wall 73 is shielded from the second space 71B so that air does not freely flow. In some cases, the wall surface constituting the outer shell of the storage chamber 21 may have a ventilation hole. For example, when a plurality of metal thin plates are connected to each other to form an outer wall of the storage chamber 21, the tip of a claw formed in the other thin plate is inserted into a hole formed in one thin plate and engaged with the hole. When the method is adopted, even if a slight gap is formed between the claw and the hole, it is defined as "partitioned". Of course, the storage chamber 21 may be a storage chamber 21 in which only the front surface is opened and integrally molded into a cylindrical shape to improve airtightness.

In FIGS. 1, 10, and 12, 22 is an opening formed on the front side of the storage chamber 21, and this opening serves as an “insertion port” into which the first cooking utensil 9 can be inserted. Called "mouth".

The distance (depth dimension) L2 from the frontmost edge of the insertion port 22 of the storage chamber 21 to the rear wall 23 constituting the back surface of the storage chamber 21 is, for example, 30 cm. The depth dimension L2 is set to be larger than the maximum length of the first cooking utensil 9 including the handle 9D, and the first cooking utensil 9 is inserted and stored in the storage chamber 21 in the front-rear direction. can. Since the first cooking utensil 9 is the largest item that can be freely taken out and stored in the storage chamber 21, the size of the insertion port 22 is determined in consideration of the external dimensions of the cooking utensil 9. Other items that can be stored in the storage chamber 21 include, for example, an instruction manual attached to the cooker 1 and a detergent that simply cleans the upper surface of the top plate 4 and the surface of the operation unit 12 after cooking. Alternatively, there are other cooking utensils 10 and 11 (including the lid attached to them, if any).

The distance (height dimension) HS from the upper surface of the bottom wall surface 21U of the storage chamber 21 to the lower surface of the ceiling wall 21H is sufficiently larger than the maximum height dimension of the entire cooking utensil 9 including the picking 9C, for example, 10 cm. .. Further, the width WX is constant from the insertion port 22 to the back side. The frontage (width dimension) of the insertion port 22 is, for example, 15 cm. Therefore, the planar shape of the storage chamber 21 is elongated and rectangular from the insertion opening 22 toward the rear.

The size (width and height dimensions) of the insertion port 22 of the storage chamber 21 is set so that the dish portion 9A and the lid 9B of the above-mentioned cooking utensil 9 can be inserted in a state of being overlapped with each other. When the user stores the lid 9B and the dish 9A, it is not necessary to separate the lid 9B and the dish 9A or change the direction, which is convenient.

The insertion port 22 is preferably on the front side of the top plate 4 on which the above-mentioned operation unit 12 is located, that is, on the front side of the main body case 3 from the viewpoint of user workability. Is provided on the front surface of the main body case 3.

In FIGS. 1, 8, and 10, 26 is a shallow container-shaped saucer (also referred to as a “tray”) having a rectangular planar shape and is made of a metal or plastic material. For example, it is formed by press-molding a thin aluminum plate. Since the depth dimension L1 of the inner portion of the saucer 26 is about 1 cm smaller than the depth dimension L2 of the storage chamber 21, it can be completely stored inside the storage chamber 21 (see FIG. 10).

The saucer 26 can be completely pulled out from the storage chamber 21 as shown in FIG. 1, but even if it cannot be completely pulled out as shown in FIG. 11, a predetermined range is shown as shown in FIG. It would be good if it could be pulled out to LD. This point will be described in detail later.

In FIGS. 1, 10, and 12, reference numeral 30 denotes a cover having a horizontally long rectangular front shape, which is entirely formed by integrally molding plastic. Reference numeral 31 is a handle on which the user hangs a finger when moving the cover 30, and includes a handle portion 31A. The handle 31 is not always necessary, and for example, a hole or a through hole serving as a handle may be formed in the cover 30 and substituted. The cover 30 and the saucer 26 may be integrally connected by an adhesive, or may be connected by a connecting metal fitting so that the user can separate the saucer 26 and the cover 30 when cleaning the saucer 26. good. In FIG. 10, reference numeral 29 is the adhesive, but this adhesive is not shown in FIG.

In FIG. 1, 44 is a right cover (also referred to as a “decorative plate”) having a square front shape, and is entirely formed by integrally molding plastic. This right cover covers the right side portion of the storage chamber 21 from the insertion port 22 on the front surface of the main body case 3. The right cover has the same thickness as the cover 30, and is fixed to the front wall surface of the main body case 3 so as to be adjacent to the right side of the cover 30. The height dimensions of the right cover 44 and the cover 30 are the same, and the surface colors of both are also the same. Note that FIG. 6 shows the outer shapes of the cover 30 and the right cover 44 for reference with broken lines. In FIG. 6, W1 shows the width dimension of the cover 30, and is set to be larger than the width dimension of the insertion port 22, in other words, the frontage dimension.

In FIG. 10, reference numeral 45 denotes a sealing material attached to the front surface of the main body case 3 at a position directly above the insertion port 22. This sealing material is made of a highly elastic material such as silicon rubber, and when the insertion port 22 is closed by the cover 30, the tip of the sealing material comes into contact with the back surface of the handle portion 31A. The sealing material 45 does not have to keep the insertion port 22 side of the storage chamber 21 completely airtight. That is, with the cover 30 closed, the storage chamber 21 may have a gap (for example, a gap of about several mm) between the edge of the insertion port 22 and the cover 30 to allow air flow. ..

In FIG. 10, 30F shows the front surface of the cover 30, and this front surface is furniture such as a door or a drawer that exists adjacent to the front surface of the cover 30 when the cooking cooker 1 is incorporated in the kitchen furniture 2. It is flush with the surface material 40. In other words, when the heating cooker 1 is incorporated, the front surface 30F of the cover 30 is positioned so as to be aligned with the front surface 40F of the furniture surface material 40 when viewed from directly above. The furniture surface material 40 and the cover 30 can give the user a sense of design as if the kitchen furniture 2 is a unified flat surface even when the kitchen furniture 2 is viewed from the front or diagonally from the front. The position of the front surface of the right cover 44 is also aligned with the position of the front surface 30F of the cover 30.

Similarly, in FIG. 10, 2F shows the front surface (front surface) of the kitchen furniture 2. When the cooker 1 is incorporated in the kitchen furniture 2, the front surface of the cover 30 is located at a position that matches the front surface 2F of the kitchen furniture 2 or at a position that is slightly recessed (for example, about several mm) from the front surface 2F. It is designed to be. FIG. 5 shows an example in which the position is slightly retracted.

In FIG. 3, reference numeral 41 denotes a furniture surface material located at a position different from that of the furniture surface material 40. The furniture surface material 41 is a structure such as a door or a drawer that exists adjacently on the right side of the cooker 1 when the cooker 1 is incorporated in the kitchen furniture 2. The position of the front surface 44F of the right cover 44 is also aligned with the position of the front surface 41F of the furniture surface material 41. As a result, the surface of the cover 30 and the front surfaces 40F and 41F of the furniture surface materials 40 and 41 are all aligned on the same vertical surface.

In FIG. 5, reference numeral 43 denotes 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 49 for kitchen utensils, foods, and the like.

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 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 cooker 1 are not intended to be designed by the same manufacturer in the present invention. In fact, the kitchen furniture is manufactured and sold by a kitchen furniture such as a sink and a housing equipment manufacturer. , The cooker 1 is manufactured and sold by a home appliance manufacturer. The two types of furniture surface materials 40 and 41 may be the same. Further, these furniture surface materials 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.

In FIGS. 1, 2, and 3, the colors and surface forms (pattern, glossiness, unevenness, etc.) of the front surfaces 30F and 44F of the cover 30 and the right cover 44 are the furniture surface materials 40 and 41. When combined with the color and surface morphology of the front of the furniture, the unified design is further enhanced. For example, when the entire front surface of the furniture surface materials 40 and 41 is unified with a single color or wood grain, the front surface 30F of the cover 30 and the front surface 44F of the right cover 44 are also unified with the same single color or wood grain design. For example, only the front 30F and 44F do not stand out in the kitchen furniture 2. The colors and patterns on the front surfaces of the cover 30 and the furniture surface materials 40 and 41 may be different from each other to show the presence of the cover 30 covering the insertion slot 22 of the storage chamber 21. Reference numeral 42 is a frame line printed on the front surface of the furniture surface materials 40 and 41, which does not form physical unevenness on the front surface of the furniture surface materials 40 and 41, but is made of glossy metal. A thin plate or the like may be attached to give a high-class feel.

In the kitchen furniture 2 shown in FIG. 2, since the cooking cooker 1 is incorporated on the leftmost side, the furniture surface material 41 is adjacent to the right side of the right cover 44, but it is located in the center of the kitchen furniture 2. When the heating cooker 1 is incorporated, the furniture surface material 41 is adjacent to the left side of the cover 30, while the furniture surface material 41 is adjacent to the right side of the cover 30. Even in such a case, as described above, only the portion of the cooking cooker 1 does not protrude forward, and the entire front surface of the kitchen furniture 2 can be in a state of exhibiting substantially one flat surface.

As shown in FIG. 11, when the cover 30 is pulled forward, the saucer 26 can be pulled forward from the storage chamber 21, but it is preferable to limit the pulling amount to a certain limit. Since the above-mentioned first cooking utensil 9 is placed in the saucer 26, it is provided with a mechanism for preventing the saucer 26 from being pulled out more than necessary and preventing the saucer 26 from falling. Not. However, this can be easily realized by providing a protrusion on the rear portion of the storage chamber 21 saucer 26, and providing a stopper inside the storage chamber 21 so as to hit the saucer 26 when it is pulled out to a certain limit position.

In FIG. 11, the LD shows the maximum withdrawal amount when the cover 30 is pulled forward. The maximum drawer amount is set so that the first cooking utensil 9 can be lifted from above the saucer 26 and carried out from the insertion slot 22 of the storage chamber 21. For example, it is 25 cm. Further, as shown in FIG. 11, the saucer 26 is configured to be supported substantially horizontally even when the saucer 26 is pulled forward to a certain limit. This is because rigid members such as support pins protruding from the left and right inner wall surfaces of the storage chamber 21 are engaged with the grooves provided on both the left and right sides of the saucer 26. As shown in FIG. 11, the weight of the first cooking utensil 9 and the weight of the cover 30 are supported by the tray 26, and the total weight of the saucer 26 is supported by the left and right wall surfaces of the storage chamber 21. There is.

In FIGS. 10 and 12, 50 is a permanent magnet attached to the rear vertical wall 26B of the saucer 26, and 51 is a magnetic sensing switch (reed switch) installed on the rear wall surface 21B of the storage chamber 21. When the saucer 26 is inserted to the innermost predetermined position of the storage chamber 21, the reed switch 51 detects the approach of the permanent magnet 50 in the operation start preparation stage of the cooking cooker 1, so that a signal indicating ON is output. Since the detection signal is input to the control device 56, the control device 56 determines that the cover 30 is closed and cooking can be started. That is, the reed switch 51 constitutes a part of the safety device SD. It can be seen that the "safety device" referred to here is composed of both the control device 56 and the reed switch 51.

As shown in FIG. 11, the storage chamber 21 is surrounded by a series of wall surfaces (21B, 21L, 21R, 21T) on the left and right sides, the upper and lower surfaces, and the rear side excluding the insertion port 22, which will be described later. It is partitioned as a closed space in which the cooling air of the first blower BM1 does not enter. Therefore, the cooling air of the first blower BM1 does not substantially flow into the space of the storage chamber 21. "Substantial" means that the wind is not intentionally supplied, and does not mean that the strict airtightness such that there is absolutely no movement of gas is maintained.

The series of wall surfaces (21B, 21L, 21R, 21T) of the storage chamber 21 are all made of a metal that does not easily rust, for example, a thin metal plate such as a zinc steel plate or a magnetic stainless steel plate, and are assembled into a box shape by welding or screwing to each other. ing. When the storage chamber 21 is formed of a metal plate in this way, the heat-resistant temperature of the storage chamber itself is improved, and even if the first cooking utensil 9 that remains hot is stored, the storage chamber 21 is burnt or deformed. It is possible to prevent such a situation.

Next, the internal structure of the main body case 3 will be described.
As shown in FIGS. 8 and 10, the internal space of the main body case 3 includes an upper space 70 and a lower space 71. Reference numeral 72 is a first partition wall extending laterally that separates the two spaces. The first partition wall is formed of a plastic plate or a metal plate. It may be formed by connecting two or more plastic plates or metal plates, but it has a large flat area that reaches the inside of the body 3U of the main body case 3 and the inside of the rear plate 3H, respectively.

In FIG. 8, the lower space 71 is composed of a first space (also referred to as “left space”) 71A and a second space (also referred to as “right space”) 71B.
Reference numeral 73 denotes a second partition wall in the vertical direction that partitions the lower space 71 to the left and right, and is made of a thin metal plate or plastic.
CL4 is a vertical center line indicating the left-right center of the main body case 3.

In FIG. 8, SP1 is a gap formed between the lower surface of the first partition wall 72 and the upper wall surface 21T of the storage chamber 21, and is set to be at least 1 cm or more. SP2 is a gap formed between the left side surface of the second partition wall 73 and the right wall surface 21R of the storage chamber 21, and is set to 30 mm to 50 mm. The position of the upper wall surface 21T of the storage chamber 21 is such that the distance H2 from the left side heating coil 8L is at least 50 mm in order to reduce the magnetic influence of the upper wall surface 21T from the left side heating coil 8L. It is preferably set to a position separated by 60 mm or more. In fact, in this reference form, the spacing H2 is 65.9 mm.

As shown in FIG. 6, since the central heating coil 8M is also located directly above the storage chamber 21, the distance H2 formed between the central heating coil 8M and the upper wall surface 21T of the storage chamber 21 is also As in the case of the left side heating coil 8L, the position is set so as to be at least 50 mm, preferably 60 mm or more away. In fact, in this reference form, the spacing H2 is 65.9 mm.

In FIG. 8, 72A is a communication port formed at the right end of the first partition wall 72. Reference numeral 74 is a ventilation duct that covers the three heating coils 8 and the upper part of the communication port 72A in a series. The whole is formed by integrally molding plastic, and the entire bottom surface has an open vertical cross-sectional shape. Reference numeral 74A is a ventilation hole formed in a portion of the air duct facing the heating coil 8 and a large number thereof is formed in a range facing the lower surfaces of the three heating coils 8.

In FIG. 8, reference numeral 75 is a cooling air passage formed between the upper surface of the first partition wall 72 and the ventilation duct 74. Reference numeral 74B is a branching protrusion integrally formed in the central portion of the blower duct 74, whereby the cooling air flowing through the cooling air passage 75 from the right side heating coil 8R side is divided into two in the middle, and one is on the left side. The flow flows directly below the heating coil 8L, and the other flows directly below the central heating coil 8M. The state of this branch is shown by a broken line arrow in FIG. The height of the cooling air passage 75, that is, the distance H1 from the air duct 74 to the first partition wall 72 is set to at least 20 mm or more. If this interval H1 is narrow, there is a concern that the resistance will increase for the cooling air to travel through the ventilation duct 74, the air will not reach the end of the ventilation duct 74, and the cooling efficiency of the left heating coil 8L and the central heating coil 8M will drop. There is.

In FIGS. 9 and 11, 57 is a cooling unit, which includes a cylindrical or box-shaped control box 58 made entirely of plastic, and three inverter circuit boards 55 installed in the control box. ing. On the inverter circuit board 55, a large number of circuit elements 59 such as electric power control electronic components and heat dissipation fins (also referred to as "heat sinks") to which these electronic components are attached are mounted. The circuit element 59 includes driving components such as an insulated gate bipolar transistor (IGBT) that operates as an inverter circuit and a freewheel diode (FWD) connected in antiparallel to the isolated gate bipolar transistor (IGBT). The heat dissipation fin is a component for enhancing the heat dissipation performance of the IGBT.

The three inverter circuit boards 55 are assigned to the heating coil 8 one by one. As shown in FIGS. 5, 6, and 8, these inverter circuit boards 55 are vertically installed at equal intervals, and cooling air passes through both sides of each inverter circuit board 55.

In FIG. 8, 58A is an opening formed on the ceiling surface of the control box 58, and has substantially the same opening area at a position corresponding to the communication port 72A of the ventilation duct 74. Since the opening 58A is installed in close contact with the mouth edge of the communication port 72A, the cooling air supplied to the inside of the control box 58 is guided to the inside of the ventilation duct 74 without leaking. The 58B is an inclined surface integrally formed from the bottom surface to the front surface on the most downstream side in the internal space of the control box 58, and is provided for the purpose of guiding the air blown from the first blower BM1 to the opening 58A side.

As shown in FIG. 9, the cooling unit 57 has either a blower case connection type or a blower case built-in type. That is, there is a form in which the blower case of the first blower BM1 is brought into close contact with the inlet opening of the control box 58, and a form in which the first blower BM1 is inserted and installed inside from the inlet opening of the control box 58. In the reference form 1, the cooling unit 57 is formed in any of these forms. Reference numeral 76 is a motor described later. 9A is a plan view showing the appearance of the cooling unit 57 connected to the blower case, and FIG. 9B is a cross-sectional view showing the structure of the cooling unit 57 built in the blower case. In both FIGS. 9A and 9B, the first blower BM1 is an example using an axial fan with a motor, and is a different type from the multi-blade blower of Reference Form 1. Reference numeral 113 indicates an outlet, and 112 indicates an inlet.

Since the cooling unit 57 is housed in the second space 71B and the control box 58 is in the cooling unit 57, the high frequency power supply circuit centered on the three inverter circuit boards 55 is this. It is stored in the control box. Necessary wiring such as a power supply line from this control box to each of the heating coils 8R, 8L, 8M goes over the second partition wall 73, goes to the top of the ventilation duct 74, and spreads horizontally in the upper space 70. To the target connection terminal.

In FIGS. 6, 8 and 10, 77 is a partition wall for partitioning the rear portion of the upper space 70 back and forth, and 78 is a left side of the space partitioned front and back inside the main body case 3 by the partition wall 77. It is a partition plate that divides into the exhaust side space 79B.

Reference numeral 38 is a partition plate (third partition wall) located substantially above the second partition wall 73 at both front and rear ends, and the intermediate portion is located on the right side of the right side heating coil 8R. In this way, it is installed long in the front-rear direction in the upper space 70. The partition plate 38 prevents the space on the left side of the partition plate 38 from communicating with the intake side space 79A on the right side of the partition plate 38. Therefore, the upper surface of the partition plate 38 is in contact with the lower surface of the top plate 4. The partition plate 39 prevents the cooling air blown from the first blower BM1 to the heating means 8 from returning to the intake side space 79A. The intake side space 79A is shown in FIG. The suction port 112 of the first blower BM1 faces the intake side space 79A.

The partition plate 38 and the second partition wall 73 may be integrated. That is, the second partition wall 73 and the third partition wall 38 may be connected or integrally formed to form one member. Further, the partition plate (third partition plate) may not be formed of a rigid plate material, but may be formed of an elastic sealing material such as rubber or urethane foam. The partition plate 38 is a member that can be omitted in some cases. For example, on the upper space 70, the cooling air blown from the blower duct 74 does not return to the suction port 112 of the first blower BM1 without being discharged to the outside of the main body case 3 (so-called “no shortcut”). ") In that case, it is not necessary to provide it.

The first blower BM1 protrudes to the rear of the partition wall 77 in a plan view and is located close to the rear surface plate 3H of the main body case 3, and the air suction port 112 (see FIG. 10) faces the intake side space 79A. I'm out. As the first blower BM1, various types of fans such as an axial fan, a (multi-blade) centrifugal fan (sirocco type, turbo type), and a mixed flow fan are used.

With the above configuration, the first blower BM1 started operation at the same time as the start of induction heating cooking, and sucked and sucked fresh air from the outside of the main body case 3 via the intake side space 79A. Cooling air is supplied to the inside of the cooling unit 57. Then, the inverter circuit board 55 and then the heating coils 8R, 8L, and 8M are cooled, and the cooling air is discharged to the outside of the main body case 3 via the exhaust side space 79B.

Next, the configuration of the control relationship of the cooking device 1 will be described with reference to FIG.
Reference numeral 61 denotes a main power switch that is opened and closed by the user, and is connected to a 200 V commercial power source 60 via a power plug (not shown). 14 is an operation key for a main power switch operated by the user, 62 is a power circuit to which electric energy is supplied via the main power switch 61, and 56 is a power circuit to which a predetermined constant pressure current is supplied. It is a control device that is mainly composed of a microcomputer.

The microcomputer 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 in advance an energization control program corresponding to various cooking menus (the storage unit). Is stored). Further, apart from the storage unit (ROM, RAM) of the microcomputer, a large-capacity storage device 56R for recording abnormality monitoring information is built in.

During the induction cooking, the control device 56 monitors the presence or absence of an electrical abnormality. Therefore, although not shown, the inverter circuit board 55 is provided with a plurality of voltmeters, ammeters (current sensors), and the like. Further, the control device 56 obtains temperature information from the temperature detection circuit 63 and monitors whether or not the main part of the cooking cooker has an abnormally high temperature. For example, the display screen 20 is composed of a liquid crystal display substrate, but is relatively sensitive to heat. Therefore, the display screen 20 is monitored through a temperature detection circuit 63 so as not to exceed a predetermined temperature (for example, 60 ° C.), and the predetermined temperature is measured. When the temperature exceeds 65 ° C., the control device 56 determines that the temperature exceeds the abnormal preliminary state (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. The control device 56 is recognized as a true abnormal state).

In this abnormal preliminary state, the heating operation does not stop immediately, but is improved by increasing the blowing capacity of the first blower BM1 that cools the internal space of the main body case 3. However, when the temperature exceeds 65 ° C., an abnormal state is determined by the control device 56, and the heating operation is immediately stopped. Therefore, for example, the power supply of the inverter circuit 55R that supplies high frequency power to the right heating coil 8R is cut off.

Then, at least, the change state of the electric and physical (as an example, the temperature of the display screen 20 described above) of the main part of the cooking device 1 during the period from the abnormal preliminary state to the emergency stop is shown (abnormality monitoring). The information is stored in the storage device 56R of the control device 56. The abnormality monitoring information stored in the storage device 56R reflects the history of electrical and physical changes from the time when the main power switch 61 is turned on to the time when the cooking is stopped. Therefore, information on the cooking menu selected thereafter (for example, "boiled water", "simmered", "fried food", etc.) and the thermal power of induction heating is 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 56R up to that point.

Further, in this reference mode 1, in order to monitor the operation of the cooking device 1 over a wider range and acquire data, the monitoring information of the period from turning on the main power switch 61 to the emergency stop of the induction cooking is controlled. The device 56 can be acquired.

Three inverter circuits 55L, 55M, and 55R are built in each of the three inverter circuit boards 55.
The inverter circuit 55L is for supplying a high frequency current to the induction heating coil 8L on the left side, and is connected to a well-known resonance circuit to which a resonance capacitor or the like is connected.

The 55R is an inverter circuit for supplying a high frequency current to the right side heating coil 8R. Further, 55M is an inverter circuit for supplying a high frequency current to the central heating coil 8M.

The three inverter circuits 55L, 55M, and 55R are driven independently of each other by the control device 56.

Reference numeral 64 denotes a voice synthesizer that synthesizes electronically created voice, and the speaker 65 notifies the user of operations and notifications when an abnormality occurs each time.

Reference numeral 63 is the temperature detection circuit described above. This temperature detection circuit includes the temperature of the first cooking utensil 9 on the top plate 4 heated by the three heating coils 8L, 8M, and 8R described above, the temperature of the top plate 4, and the atmosphere of the cooling space 52. Receives temperature detection information from a plurality of temperature sensors (not shown) for detecting the temperature of the temperature, the inverter circuits 55L, 55M, 55R, the display screen 20, etc., and sends the temperature detection results to the control device 56. .. The temperature sensor (not shown) may be either a non-contact type such as an infrared sensor or a contact type such as a thermistor, and they are used alone or in combination.

Reference numeral 66 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 62 connected to the main power supply switch 61 described later, and is driven for a long period of time. It is supposed to be done. 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 control device 56, and is set to the correct date and time at the manufacturing stage of the cooking cooker 1. .. 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 control device 56. Therefore, the abnormality monitoring information recorded in the storage device 56R of the control device 56 is always recorded and stored at the same time with an accurate time.

Reference numeral 67 denotes a vibration-sensitive 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 control device 56, and the control device 56 receives the signal and causes an earthquake. It is determined that it has occurred, and the power supply of all the heating means in use is shut off instantly.

68 is a wireless communication means. This wireless communication means may be built in the main body case 3 of the cooking cooker 1 or may be connected to the power supply circuit 62 of the cooking cooker 1 in the form of an adapter described later. The adapter format is adopted.

The "adapter" refers to a control device provided between an individual home electric appliance such as the cooker 1 and its power source. For example, the adapter referred to here refers to an adapter as shown in JP-A-2011-205821 and JP-A-2011-55623, and is an electric device having a power plug and an outlet and having the outlet controlled to be energized. (In this reference form 1, the cooking device 1) is connected. Then, when the adapter receives the power command signal by wireless communication, it limits or cuts off the power supply of the home electric appliance (heating cooker 1) to be controlled. In this way, an adapter is connected to an existing home appliance (cooker 1), and a power command signal is sent to the adapter from a power control device (not shown) that limits the total amount of power in the home, and the signal is used. Since the adapter controls the cooking cooker 1, there is an advantage that the electric power can be centrally controlled by the power command device by interposing the adapter on the power supply side in the existing cooking cooker 1.

As shown in FIG. 5, the operation unit 12 has an input key 18. When the input key 18 is touch-operated, the control device 56 is connected to a wide area communication network in the external space of the home via the wireless communication means 68, and is connected to a server (not shown) installed by the information provider. , Acquire information useful for the use of the first cooking utensil 9. The acquired information is stored in the storage device 56R. Further, it is displayed on the display screen 20, or in addition to this display, it is further notified by voice from the speaker 65 by the voice synthesizer 64.

Reference numeral 69 denotes a drive circuit for driving the display screen 20. This drive circuit is connected to the control device 56. Although not shown, the display unit drive circuit 69 includes a display memory, a display controller, an interface, a power supply circuit, a common driver, and a segment driver, respectively.

In FIG. 13, reference numeral 80 denotes a drive circuit for driving the first blower BM1, and the operation is controlled by the control device 56.

Given the above configuration, the cooking operation will be described next.
Next, the configuration of the control relationship of the cooking device 1 will be described with reference to FIG.
First, when the user turns on the main power switch 61, electric energy is supplied to the power circuit 62 via the main power switch. Then, a predetermined constant pressure current is supplied from this power supply circuit, and the control device 56 is started.
The control device 56 activates the temperature detection circuit 63, the speech synthesizer 64, and the display unit drive circuit 69, and when an abnormal temperature state is not detected by the temperature detection circuit and when an abnormal voltage or current is not detected. Completes the self-check operation at startup. Then, the fact that cooking can be started is displayed on the display screen 20, and the voice synthesizer 64 also notifies through the speaker.

Therefore, the cover 30 of the storage chamber 21 is pulled out toward the front, and the first cooking utensil 9 is taken out and placed at a position directly above the left side heating coil 8L, for example, as shown in FIGS. 4 and 10. The first cooking utensil 9 can be used for induction heating cooking only by the dish portion 9A, but when the lid 9B is used at the same time, the food to be cooked (for example, fish, meat, etc.) does not scatter and the hot air. Does not escape, so the heating efficiency is improved.

When the reed switch 51 constituting a part of the safety device SD is opened (OFF) after the control device 56 completes the self-check operation at the time of startup, the saucer 26 is set at the innermost part of the storage chamber 21. It is determined that the product is pulled out from the position. After that, it is detected whether or not an object to be heated such as a metal pot is placed on any of the three heating coils 8L, 8M, and 8R (various methods have already been proposed for such detection methods). Since it is, detailed explanation is omitted).

When the control device 56 detects that the first cooking utensil 9 is on the left side heating coil 8L or the right side heating coil 8R, the display screen 20 and the voice synthesizer 64 set the cooking conditions to the operation unit 12. Encourage input from.
When the first cooking utensil 9 is placed on the left side heating coil 8L, the heating power, the heating time, etc. are input using the three input keys 17 on the left operation unit 12L, and the input key 17 is used. If a command to start heating is input with one of the above, the inverter circuit 55L is driven by the control device 56, and induction cooking is executed.

When the input key 18 on the operation unit 12 is touch-operated before, during, or after the execution of such induced cooking, the control device 56 is outside the home via the wireless communication means 68. Information useful for using the first cooking utensil 9 is acquired in real time from a server (not shown) installed by an information provider connected to a wide area communication circuit network in space, and the acquired information is stored in the storage. While it is stored in the device 56R, it is displayed on the display screen 20, or in addition to this display, it is further notified by voice from the speaker 65 by the voice synthesizer 64, so that the user uses the first cooking utensil 9. When doing so, useful external information can be used, which is convenient. For example, when grilling fish, it is possible to know the thermal power of the left heating coil 8L.

During the execution of such induction heating cooking, the user can stop the heating operation at an arbitrary timing, and the stop command can be given by one of the input keys 17. In an emergency, the automatic stop can be easily performed by pressing the operation key 14 of the main power switch 61.

The first cooking utensil 9 that has finished induction heating first pulls out the cover 30 of the storage chamber 21 toward the front, pulls out the saucer 26 forward from the storage chamber 21, and then the first cookware 9 is placed on the saucer 26. The cooking utensil 9 of the above can be placed. Even if the first cooking utensil 9 is still immediately after cooking and the temperature is high, there is no problem because the saucer 26 is made of metal or heat-resistant plastic.

The control device 56 detects that the saucer 26 has been returned to the innermost predetermined position of the storage chamber 21 when the reed switch 51 constituting a part of the safety device SD is turned on. This state is also a state in which the cover 30 closes the insertion port 22. Therefore, the storage room 21 has returned to a closed space where there is no air communication with the outside. Therefore, as described above, the internal atmosphere of the storage room 21 is affected by the influence of the first cooking utensil 9 having a high temperature. It is expected that the temperature will rise. However, in this reference form 1, the storage chamber 21 is designed in consideration of such a temperature rise, and the outer temperature of the main body case 3 and the surface temperature of the cover 30 are not raised above a predetermined temperature.

As one of the measures to suppress the temperature rise of the internal atmosphere of the storage chamber 21, ventilation holes may be provided on the back surface, the ceiling surface, or the like of the storage chamber 21 so that the storage chamber 21 communicates with the cooling space 52. In that case, if the air is cooled more positively, a part of the cooling air of the blower BM is introduced into the storage chamber 21 and discharged from the inside of the storage chamber 21, and finally the hot air of the storage chamber 21 is discharged. Similar to the exhaust flow from the exhaust port 6 (see FIG. 10), the air may be discharged from the main body case 3 to the outside.

In the above description, the first cooking utensil 9 is used for inductive cooking, but other general cooking utensils such as metal pots and frying pans, that is, the above-mentioned second and third cooking utensils. Cooking is possible with 10 and 11.

Next, the operation of the control device 56 when the touch-type input key 19 for a confirmation command requesting the existence result of the first cooking utensil 9 is operated with respect to the control device 56 will be described. When the input key 19 is operated, the control device 56 detects whether or not the first cooking utensil 9 is inside the storage chamber 21. Therefore, it is magnetically determined that the storage chamber 21 has a sensor for discriminating between the presence and absence of the first cooking utensil 9, for example, the first cooking utensil 9 at a predetermined position on the saucer 26. Alternatively, a sensor that detects optically or by weight is separately provided. Then, when it is detected by the reed switch 51 that the cover 30 is opened and then closed, the change in magnetic, optical or weight (the weight including the saucer 26 may be sufficient) before and after the opening is changed. Judging, the presence of the first cooking utensil 9 which is made of metal and is relatively heavy (for example, weighs 500 g or more) is detected. If there is a first cooking utensil 9, the presence or absence of the cooking utensil 9 is displayed on the display screen 20 or notified by the voice synthesizer 64 immediately after the input key 19 is operated, so that the user can use the first cooking utensil 9. For example, even when another cooking is performed on the left side heating coil 8L, it is convenient because the stored state of the first cooking utensil 9 can be immediately confirmed without pulling out the cover 30 forward. ..

Next, the flow of the cooling air by the first blower BM1 will be described with reference to FIGS. 5, 6, 7, and 8.
When the inverter circuit 55L is driven by the control device 56 and the induction cooking is executed, the control device 56 activates the motor drive circuit 80 in synchronization with this, and rotationally drives the motor 76 of the first blower BM1.

Then, an intake flow as shown by an arrow 53 in FIG. 4 is generated, and fresh air outside the main body case 3 is sucked from the suction port 112 of the first blower BM1 and forced into the inside of the cooling unit 57. Be sent in. Since the sent air flow flows through the surface of the three inverter circuit boards 55 in the process of traveling from the rear to the front inside the cooling unit 57, a large number of circuit elements 59 and aluminum heat dissipation on which they are mounted are generated. While cooling the fins (not shown) and the like, the openings 58A on the ceiling surface of the control box 58 are reached.

Further, the cooling air enters the inside of the air duct 74 through the communication port 72A. Then, the cooling air passage 75 proceeds from the right side to the left as shown in FIG. 5, but a part of the cooling air passage 75 is blown upward from a large number of small ventilation holes 74A of the air duct 74 and collides with the right heating coil 8R immediately above. And take away the heat. This prevents the right side heating coil 8R from being overheated. Even when the right heating coil 8R is not driven and is not heated, such cooling air is performed during cooking.

The cooling air that has traveled through the cooling air passage 75 is divided into two at the protrusion 74B, one of which is sent to the left heating coil 8L and the other to the central heating coil 8M. Then, it is blown out from the respective ventilation holes 74A toward the central heating coil 8M and the left side heating coil 8L. This prevents the left side heating coil 8L and the central heating coil 8M from being overheated. Even when the central heating coil 8M is not driven and is not heated, such cooling air is performed during cooking. As described above, at this time, the inverter circuit 55L is driven by the control device 56, and only the left side heating coil 8L is executing the induction heating cooking. Therefore, the left side heating coil 8L is the cooling air passage 75. It is efficiently cooled by the cooling air blown from. Then, the cooled air travels rearward over the ventilation duct 74, enters the exhaust side space 79B, and is finally discharged from the exhaust port 6 into the indoor space as the exhaust flow shown by the arrow 54B in FIG. ..

Next, it will be described that the temperature rise of the storage chamber 21 is suppressed by the air flow from the first blower BM1 as described above.
Normally, the heating coil 8 is provided with a means for preventing leakage magnetic flux called a magnetic shield ring around the heating coil 8, but the first partition wall 72 and the storage chamber 21 directly below the left heating coil 8L are guided at a position directly above. There is a concern that the temperature will rise due to the influence of the heating left side heating coil 8L. In particular, when the inverter circuit 55L is driven by a 200V power supply, the influence of the high frequency magnetic field is strongly affected even below the left heating coil 8L, so that the nearest metal, for example, the first partition wall 72 made of steel plate is heated. It will also be done. Further, when the temperature of the first partition wall 72 rises, there is a concern that the storage chamber 21 in which the upper wall surface 21T is close to the first partition wall 72 via the gap SP1 is also indirectly heated. Further, when the entire storage chamber 21 or at least the upper wall surface 21T thereof is formed of a steel plate or the like, there is a concern that the temperature of the upper wall surface 21T may rise due to the influence of the high frequency magnetic field of the left side heating coil 8L.

Therefore, in this reference mode 1, a blower duct 74 is arranged between the left side heating coil 8L and the storage chamber 21, and the first blower BM1 is placed on the lower side of the blower duct, that is, on the side closer to the storage chamber 21. I decided to let the cooling air flow. According to this configuration, as shown in FIG. 6, since the air duct 74 exists in the entire lower part of the left side heating coil 8L, the temperature rise in the range of the air duct 74 is suppressed by the cooling air. Therefore, the temperature rise of the first partition wall 72 below the air duct 74 is suppressed. The cooling air supplied from the cooling unit 57 to the lower side of the left side heating coil 8L is only for cooling the inverter circuits 55L, 55M, 55R (in the case of induction heating by the left side heating coil 8L, the inverter. (Only the circuit 55L is driven), the room temperature is raised by several ° C to 10 ° C, so even when the air reaches just below the left heating coil 8L, the air is not yet warm. Therefore, the effect of suppressing the temperature rise of the first partition wall 72 can be expected.

In the reference embodiment 1, the first blower BM1 is operated for a certain period of time (for example, about several minutes to 10 minutes) even after the drive of the inverter circuit 55L is stopped by the control device 56. The control program of the control device 56 is set. Further, even after a certain period of time has passed, a plurality of temperature sensors (not shown) that transmit the temperature measurement result to the temperature detection circuit 63 are present at the ambient temperature inside the cooling unit 57, inside the exhaust side space 79B, and the top plate. Until the temperature detection circuit 63 determines that the temperature of 4 has been measured and the temperature has dropped to a predetermined temperature, the control device 56 issues a drive command to the drive circuit 80 of the first blower BM1. Therefore, even after the driving of the inverter circuits 55L, 55M, 55R is stopped, the cooling by the first blower BM1 is continued until the temperature of the upper space 70 is sufficiently lowered. The first blower BM1 may automatically switch to energy-saving operation by reducing the rotation speed of the motor 76 after the drive of the inverter circuits 55L, 55M, 55R is stopped.

The significance of the second partition wall 73 in the reference embodiment 1 will be described. Since the first cooking utensil 9 and other cooking utensils are housed in the storage chamber 21, in some cases, a wet cooking utensil immediately after washing or a hot first cooking utensil 9 can be stored. There is a possibility. In such a case, there is a concern that the temperature and humidity inside the first space 71A may be temporarily high, but the second partition 73 betweens the inside of the first space 71A and the second space 71B where the cooling unit 57 is present. However, since it is blocked so that there is neither forced convection nor natural convection of air, there is no concern that hot and humid air will be sucked into the cooling unit 57 side.

With this configuration, in the heating cooker of the reference embodiment 1, a storage chamber 21 is secured inside the main body case 3, and accessories, first cooking utensils 9, and second cooking utensils 9 are secured from the insertion port 22 in the storage chamber 21. Items such as the cooking utensil 10 can be inserted and stored, and can be taken out as needed. Moreover, it can be expected that the cooling air passes above the storage chamber 21 while the heating means 8 is being driven to suppress the temperature rise above the storage chamber 21.

According to the cooking device 1 of the reference embodiment 1, when the cover 30 covers the front surface of the cooking device 1 is adjacent to at least one of the left side and the right side of the cooking device 2 in the state of being incorporated in the kitchen furniture 2.

The decorative plate 44 is installed at a position aligned with the front surface of the kitchen furniture 2 adjacent to the decorative plate 44. Therefore, according to the cooking device 1, the front surface of the cooking device 1 and the front surface of the kitchen furniture 2 can be given a unified flat feeling.

According to the heating cooker 1 of the reference embodiment 1, the cooking utensil 9 can be pulled out forward by the saucer 26 integrated with the cover 30, and the operability of the user can be improved.

Further, the cooking device 1 of the reference embodiment 1 detects a state in which the cover 30 is open in the control device 56, and starts operation of the inverter circuits 55L, 55M, 55R in the state where the cover is open. Since the safety device SD (50, 51) is provided, the start of operation of the inverter circuits 55L, 55M, 55R is automatically prohibited when the cover 30 is open, which enhances safety. be able to.

Further, the heating cooker 1 of the reference embodiment 1 instructs the operation unit 12 to acquire cooking reference information via the wireless communication means 68 when the first cooking utensil 9 is used.

Further, the heating cooker 1 of the reference embodiment 1 includes a tubular or box-shaped control box 58 made entirely of plastic, and three inverter circuit boards 55 installed in the control box. Since a large number of circuit elements 59 such as electric power control electronic parts and heat dissipation fins to which these electronic parts are attached are mounted in the cooling unit 57, the first blower BM1 puts them in the control box 58. The inverter circuit board 55, a large number of circuit elements 59, and the like can be efficiently cooled by the cooling air that is forcibly sent.

Further, this reference form 1 has the following characteristic configuration.
That is, the cooking device 1 in this reference form 1 is
The main body case 3 supported by the kitchen furniture 2 and
A storage chamber 21 that is partitioned inside the main body case 3 and leads to the outside of the main body case 3 via an insertion port 22 formed on the front surface.

The configuration is set so that the position is 5 cm or more away.

Because of this configuration, even if the upper wall surface 21T of the storage chamber 21 is made of magnetic metal, it is hardly affected by magnetic influence from the left side heating coil 8L and the central heating coil 8M installed above. Since the interval H2 is secured as described above, the influence that the upper wall surface 21T itself is induced and heated can be eliminated. Thereby, the left side heating coil 8L and the central heating coil 8M can be used simultaneously or individually on the top plate 4 for induction heating cooking. Moreover, the cooling air from the first blower BM1 suppresses the temperature rise of the first partition wall 72 directly above the storage chamber 21, and the excessive temperature rise of the upper wall surface 21T itself is avoided, so that the storage chamber 21 is overheated.

A modified example of Reference Form 1.
16 and 17 show a cooking device according to a modified example of the reference embodiment 1 of the present invention. A major feature of this modification is that the ventilation duct 74 of Reference Form 1 is separated into three parts. In the following description, the same or corresponding parts as those in FIGS. 1 to 15 may be designated by the same reference numerals, and duplicate description may be omitted.

As shown in FIG. 16, the ventilation duct 74 of this modified example is formed separately into three parts. That is, the 74R is the right air blow duct arranged on the far right side, and is arranged directly under the right side heating coil 8R.
Reference numeral 4M is a central ventilation duct, which is arranged directly below the central heating coil 8M. 74L is the left side ventilation duct. The underside of all these ventilation ducts is open, covering the sides and ceiling in a series.

As shown in FIG. 16, there are two openings formed on the ceiling surface of the control box 58, one of which is the opening 58A on the side closer to the first blower BM1. The other is an opening 58B (not shown) on the far side of the first blower BM1.

The communication port of the air duct 74 is formed at a position corresponding to the two openings 58A and 58B, respectively. Since the two openings 58A and 58B are installed in close contact with the rims of the two communication ports 72A and 72B, respectively, the cooling air supplied to the inside of the control box 58 does not leak. It is divided into two and guided to the inside of the air duct 74.
That is, there are two types of cooling air, one is cooling air flowing from one opening 58A to one communication port 72A, and the other is cooling air flowing from the other opening 58B to the other communication port 72A.

Reference numeral 46 denotes a separation wall installed in the right air blowing duct 74R, which divides the downstream side in the flow of cooling air from the communication port 72A and the communication port 72B into two.

The left end portion of the right air blow duct 74R communicates with the right end portion of the left air blow duct 74L with the connecting seal member 37A interposed therebetween. The connecting seal member 37A is rich in elasticity and is for preventing airflow from leaking, and is installed in a compressed state between the left end surface of the right side air duct 74R and the right end surface of the left side air duct 74L. The airtightness of the cooling air passage 75 continuously formed inside the two air ducts is maintained. The connecting seal member 37A has a ring shape as a whole, and its thickness is 10 mm or less.

The left end portion of the right air blow duct 74R communicates with the right end portion of the central air blow duct 74M with the connecting seal member 37B interposed therebetween. The connecting seal member 37B is also highly elastic and is for preventing airflow from leaking. The connecting seal member 37B is also installed in a compressed state between the right side ventilation duct 74R and the central ventilation duct 74M. The connecting seal member 37B has a ring shape as a whole, and its thickness is 10 mm or less.

In FIG. 17, SP1 is a gap formed between the lower surface of the first partition wall 72 and the upper wall surface 21T of the storage chamber 21, and is set to be at least 1 cm or more. SP2 is a gap formed between the left side surface of the second partition wall 73 and the right wall surface 21R of the storage chamber 21, and is set to 30 mm to 50 mm. The position of the upper wall surface 21T of the storage chamber 21 is such that the distance H2 between the left side heating coil 8L and the center heating coil is at least 50 mm in order to reduce the magnetic influence from the left side heating coil 8L and the center heating coil. , Preferably set to a position separated by 60 mm or more. In fact, in this modification, the spacing H2 is 70 mm.

As shown in FIG. 17, the left ventilation duct 74L is an integrally molded product including two portions, a portion 74L1 having a high height to the ceiling surface and a portion 74L2 having a low height to the ceiling surface. It is made of heat resistant plastic. If the portion 74L2 having a low height to the ceiling surface is formed long, the ventilation resistance (pressure loss of the air passage) becomes large, and there is a concern that a sufficient air volume cannot be supplied, so it is better to be short. In this modification, the length LL is 150 mm or less (see FIG. 16).

As shown in FIG. 17, the distance H1 from the portion 74L1 having a high height to the ceiling surface of the left side ventilation duct 74L to the first partition wall 72 is set to 30 mm. However, the distance SH from the portion 74L2 having a low height to the ceiling surface to the first partition wall 72 is set to 20 mm. That is, even in this modification, the actual height of the cooling air passage 75 is secured to be 20 mm. If this interval SH is narrower than 20 mm, there is a concern that the cooling air will have a large resistance to travel through the air duct 74, and the air will not reach the end of the left air duct 74L.

Next, the flow of the cooling air by the first blower BM1 will be described with reference to FIGS. 16 to 17.
When the inverter circuit 55L is driven by the control device 56 and the induction cooking is executed, the control device 56 activates the motor drive circuit 80 in synchronization with this, and rotationally drives the motor 76 of the first blower BM1.

Then, the fresh air outside the main body case 3 is sucked from the first blower BM1 as described in Reference Form 1, and is forcibly sent into the inside of the control box 58 of the cooling unit 57. The sent air flow reaches the opening 58A on the ceiling surface of the control box 58 while cooling the inverter circuit board 55 and other heat-generating electronic components.

Then, the cooling air enters the inside of the right side ventilation duct 74R from the communication port 72A on the upstream side. And a part of it spouts directly above the ventilation duct. However, in this case, since the right side heating coil 8R is not in the heating operation, the right side heating coil 8R is not cooled by the ejected air flow.

On the other hand, the remaining cooling air that has not been ejected passes through the rear side of the separation wall 46 in the cooling air passage 75 and reaches the central ventilation duct 74M. Then, it spouts directly above the duct 74M. The air ejected from the central ventilation duct 74M and the air ejected from the right air ventilation duct 74R reach the exhaust side space 79B and are discharged into the room from the exhaust port 6.

On the other hand, the cooling air that went straight through the control box 58 without exiting from the communication port 72A on the upstream side was sent from the communication port 72B on the downstream side to the inside of the right air duct 74R (front of the separation wall 46). come in. Then, it does not eject from the right side air duct 74R toward the right side heating coil 8R.

After that, the cooling air passes through the cooling air passage 75 (on the front side of the separation wall 46) and reaches the left side air duct 74L. Then, it is ejected (blowed out) from a large number of ventilation holes 74A toward the left heating coil 8L. As a result, not only the left side heating coil 8L but also the coil base 32, the ferrite 33, the magnetic shield ring 34 and the like are cooled.

Next, it will be described that the temperature rise of the storage chamber 21 is suppressed by the air flow from the first blower BM1 as described above.
As described in Reference Form 1, when the heating means 8 above the storage chamber 21 starts the induction heating operation, for example, the left heating coil 8L is strongly affected by the high frequency magnetic field even below it, and is made of, for example, a steel plate. The first partition wall 72 will also be heated. Further, when the temperature of the first partition wall 72 rises, there is a concern that the storage chamber 21 in which the upper wall surface 21T is close to the first partition wall 72 via the gap SP1 is also indirectly heated.

On the other hand, in this modification, the air duct 74 (74L, 74M) is arranged between the left side heating coil 8L and the storage chamber 21 and between the central heating coil 8M and the storage chamber 21. It was decided to flow the cooling air of the first blower BM1 to the lower side of the air duct, that is, the side close to the storage chamber 21. According to this configuration, as shown in FIG. 6, since the air duct 74 exists in the entire lower part of the left side heating coil 8L, the temperature rise in the range of the air duct 74 is suppressed by the cooling air. Therefore, the temperature rise of the first partition wall 72 below the air duct 74 is suppressed. The cooling air supplied from the cooling unit 57 to the lower side of the left side heating coil 8L is only for cooling the inverter circuits 55L, 55M, 55R (in the case of induction heating by the left side heating coil 8L, the inverter. (Only the circuit 55L is driven), the room temperature is raised by several ° C to 10 ° C, so even when the air reaches just below the left heating coil 8L, the air is not yet warm. Therefore, the effect of suppressing the temperature rise of the first partition wall 72 can be expected.

As shown in FIG. 16, since the ventilation duct 74 of this modification is divided into three parts, the right side ventilation duct 74R, the central ventilation duct 74M, and the left side ventilation duct 74L can be formed separately. Therefore, it is not necessary to prepare a large mold for plastic molding, a mold for a metal press, or the like. Therefore, there is an effect that the manufacturing cost of the ventilation duct can be reduced as compared with the reference form 1.

Reference form 2.
FIG. 18 shows a cooking device according to Reference Form 2. This reference form is characterized in that the storage chamber 21 of the cooking device 1 is further positively cooled.

Also in FIG. 18, W1 shows the width dimension of the cover 30, and is set to be larger than the width dimension of the insertion port 22 of the storage chamber 21, in other words, the frontage dimension. The area on the right side from the second partition wall 73 is entirely covered on the front side by the right cover 44 fixed to the front of the main body case 3.

With the above configuration, in the heating cooker 1 according to the reference embodiment 2, the cooling air from the first blower BM1 to the left side heating coil 8L is above the storage chamber 21 and of the first partition wall 72. Pass through the upper space. At that time, the cooling air immediately before going from the air duct 74 to the ventilation hole 74A cools the heat radiation fin 83 connected to the magnetic shield plate 82. Therefore, the magnetic shield plate 82 is cooled. Therefore, the upper wall surface 21T of the storage chamber 21 is indirectly cooled by the cooling air before going to the left side heating coil 8L.

Summary of Reference Form 2.

Moreover, in the reference mode 2, the upper wall surface 21T constituting the ceiling surface of the storage chamber 21 is indirectly cooled (via the magnetic shield plate 82) by the cooling air before going to the left side heating coil 8L, so that the reference mode is used. The effect of suppressing the temperature rise of the storage chamber 21 can be expected more effectively than 1.
Since the effect of providing the storage chamber 21 can be expected to be the same as that of the reference embodiment 1, detailed description thereof will be omitted.

It is connected to the top. As a result, a part of the cooling air supplied from the first blower BM1 to the inside of the cooling unit 57 branches at the stage reaching the rear part of the inverter circuit board 55 and flows into the branch duct 84.

The cooling air flowing into the branch duct 84 is introduced into the storage chamber 21 from the end of the branch duct 84 as shown by the broken line arrow in FIG. 20, passes through the storage chamber 21, and then the storage chamber. It is discharged to the upper space 70 from the exhaust duct 85 provided so as to penetrate the ceiling portion (upper wall surface 21T) of the 21.

Reference numeral 38 is a partition plate (third partition wall) provided so as to surround the three heating coils 8R, 8L, and 8M. In the reference form 1, it was installed in the upper space 70 for a long time in the front-rear direction. On the other hand, in the reference embodiment 3, the partition plate 38 is provided for the purpose of surrounding the cooling air blown from the first blower BM1 to the heating means 8 so as not to diffuse to the surroundings. Then, the cooling air from the first blower BM1 is efficiently guided into the exhaust side space 79B.

As shown by the broken line in FIG. 19, the exhaust duct 85 is provided so as to penetrate the ceiling portion (upper wall surface 21T) at the left corner of the rear part of the storage chamber 21, and the storage chamber discharged from the exhaust duct 85 is provided. A partition plate 39 that guides the air inside the 21 to the exhaust port 6 is installed in the upper space 70.

The partition plate 39 is provided in an L shape in a plan view so as to surround the left side and the front of the outlet of the exhaust duct 85 in a series, but it may be provided so as to surround all the front, back, left and right of the outlet of the exhaust duct 85. good.

It does not flow up to the exhaust port 6 separately. Although the position of the exhaust port 6 is shown by a broken line in FIG. 19 for reference, the position of the exhaust port 6 can be visually recognized at the position shown in FIG. 19 with the top plate 4 and the rear frame plate 5 removed. It does not mean that.

Summary of Reference Form 3.
As is clear from the above description, also in the heating cooker 1 of the reference form 3, the cooling air from the first blower BM1 to the left side heating coil 8L is above the storage chamber 21 as in the reference form 1. , It is configured to pass through the space above the first partition wall 72.

That is, since the cooling air before the temperature rises by taking the heat of the inverter circuit board 55 is directly supplied to the inside of the storage chamber 21 by the branch duct 84, the storage chamber 21 is directly cooled by the cooling air. Will be done. Therefore, the effect of suppressing the temperature rise of the storage chamber 21 can be expected more effectively than that of the reference form 1 and the reference form 2.
Since the effect of providing the storage chamber 21 can be expected to be the same as that of the reference embodiment 1, detailed description thereof will be omitted.

Reference form 4.
21 to 23 show the cooking apparatus according to the reference embodiment 4 of the present invention.
In this reference form 4, the left side induction heating portion of the cooking device 1 is characteristic. The same or corresponding parts as those in FIGS. 1 to 14 may be designated by the same reference numerals, and duplicate description may be omitted.

In FIGS. 21 to 23, the heating cooker of the reference embodiment 4 is a so-called three-port induction heating cooker provided with an induction heating unit on the left side, an induction heating unit on the right side, and a central heating unit, and is viewed in a plan view. It is equipped with a main body case 3 having a horizontally long rectangular shape (also referred to as a horizontal rectangular shape).

The outer shape of the main body case 3 is set according to the size of the outer shape covering the installation port 2A formed in the kitchen furniture 2 such as a sink.
The body 3U of the main body case 3 made of a thin metal plate is designed in a box shape having a width W3 of 540 mm (or 550 mm) and a depth DP1 of 402 mm in terms of inner dimensions. The left side heating coil 8L, the right side heating coil 8R, and the central heating coil 8M are installed inside the main body case 3, respectively. The planar size of the body portion 3U can be seen in FIG.

The top plate 4 is rectangular as shown in FIG. The heat-resistant tempered glass plate constituting the top plate 4 has a width W2 of 728 mm and a depth dimension DP2 larger than the depth dimension DP1.

In FIGS. 21 and 22, 8M is a central heating coil, and the maximum external dimension DM1 is about 100 to 120 mm.
Reference numeral 8R is a central heating coil, and the maximum external dimension DM3 is about 200 mm.

8L is a left heating coil. The MC is the main heating coil in the center of the left heating coil 8L, and is arranged close to the top plate 4 on which the object to be heated is placed. In FIGS. 21 and 22, what is indicated by the broken line circle is the range of the bottom surface portion of the object to be heated such as a metal pot.
Further, this main heating coil is finally formed by winding a coil wire into a disk shape so that the outer shape becomes circular with the center point X1 as a base point. The diameter (maximum outer diameter dimension) DA2 of the main heating coil MC is about 180 mm. This reference mode 4 has, for example, a rated maximum power consumption (maximum thermal power) of 2000 W. The main heating coil is composed of two parts, an annular inner coil and an annular outer coil connected in series to the inner coil.

SC1 to SC4 are four oval subheating coils, which are symmetrically arranged in front and back, left and right, and at equal intervals with the center point X1 of the main heating coil MC as a base point.
The four sub-heating coils SC1 to SC4 maintain a predetermined space (a size of about several mm to 10 mm. In the following description, an example of "5 mm") on the outer peripheral surface of the main heating coil MC. It is fixed to the upper surface of the coil base plate (not shown).
The four sub-heating coils SC1 to SC4 have the same planar shape, and the vertical, horizontal, and height (thickness) dimensions are all the same. Therefore, four sub-heating coils are manufactured and arranged at four locations.

As shown in FIG. 22, these four sub-heating coils SC1 to SC4 are centered in the longitudinal direction of each sub-heating coil SC1 to SC4 in the tangential direction around the main heating coil MC having a predetermined radius from the center point X1. It matches the line. In other words, it coincides with the major axis direction.
The sub-heating coils SC1 to SC4 electrically form one closed circuit in which the aggregated lines of the sub-heating coils extend while being curved in an oval shape. Further, the vertical dimensions (also referred to as height dimensions and thickness) of the main heating coil MC and the vertical dimensions of the sub-heating coils SC1 to SC4 are the same, and the facing distance between the upper surface thereof and the lower surface of the top plate is the same. It is installed and fixed horizontally so that it has the same dimensions.
The diameter of the outermost circle of the four subheating coils SC1 to SC4 is, for example, 300 mm. Therefore, the left side heating coil 8L can handle an object to be heated having a bottom surface diameter of about 320 to 350 mm.

FIG. 21 is a circuit block diagram for supplying electric power to the left heating coil 8L. It is provided with a main inverter circuit 55LM for the main heating coil MC of the left heating unit and dedicated sub-inverter circuits 55LS1, 55LS2, 55LS3, 55LS4 connected to each of the four sub-heating coils SC1 to SC4.

55R is an inverter circuit for the right side heating coil 8R, and 55M is a drive circuit for the central heating coil 8M.
The right heating coil 8R has a dual configuration of one heating coil wound in an annular shape and an outer heating coil parallel to the heating coil, and the two heating coils are independent at different timings. It can be heated and driven. Therefore, the configuration of the inverter circuit 55R is different from the configuration of the inverter circuit 55R of the reference embodiment 1. Specifically, the two heating coils are provided with dedicated inverter circuits 55R1 and 55R2, respectively. In FIG. 21, the two inverter circuits 55R1 and 55R2 are collectively represented by the reference numeral 55R.

More specifically, as described above, the maximum outer diameter DA3 of the heating coil 8R on the right side is 200 mm, which is the outer diameter of the outer annular coil.
The maximum outer shape of the inner annular coil is about 100 mm.
Therefore, for example, only the inner annular coil can be driven to induce and heat the object N to be heated having a small diameter (for example, about 80 mm to 120 mm), while the outer annular coil and the inner annular coil can be driven at the same time (or). (Alternately energized in a short time), a larger diameter, for example, about 220 mm can be heated.

Since the main inverter circuit 55LM and the sub-inverter circuits 55LS1 to 55LS4 are supplied with direct current from the commercial power supply 60 via a converter (not shown), the direct current is converted into a high frequency current and the main heating is performed respectively. It can be supplied independently (to each other) to the coil MC and the subheating coils SC1 to SC4.

In general, the impedance of the induction heating coil changes depending on the presence / absence and size (area) of the object to be heated N placed above the induction heating coil. The amount of current flowing through the inverter circuits 55LS1 to 55LS4 also changes. In the reference embodiment 4, the current detecting unit (detecting means) 87 for detecting the respective current amounts flowing through the main heating coil 55MC and the sub-heating coils SC1 to SC4 is provided. This current detection unit is a kind of the object to be heated determination unit 86, which will be described later.

In this reference embodiment 4, whether the object to be heated is placed above each coil by detecting the amount of current flowing through the main heating coil MC and the sub-heating coils SC1 to SC4 by using the current detection unit 87. Since it is estimated whether or not the bottom area of the object to be heated is larger than a predetermined value and the estimation result is transmitted to the control device 56, it is possible to accurately detect the placement state of the object to be heated. The object to be heated here includes all of the first cooking utensil 9, the second cooking utensil 10, and the third cooking utensil 11 as described in Reference Form 1.

In the reference embodiment 4, as shown in the figure, the control device 56 is connected to the current detection unit 87, and the control signal is connected to the main inverter circuit 55LM and the sub-inverter circuits 55LS1 to 55LS4 according to the placement state of the object to be heated. Is to give. That is, the control device 56 receives a signal (data indicating the placement state of the object to be heated) regarding the amount of current flowing through the main heating coil MC and the sub-heating coils SC1 to SC4 detected by the current detection unit 87, and the object to be heated. Is not placed, or if it is determined that the diameter of the object to be heated is smaller than the predetermined value (for example, 120 mm), the supply of high-frequency current to the main heating coil MC and the sub-heating coils SC1 to SC4 is prohibited. Alternatively, the main inverter circuit 55LM and the sub-inverter circuits 55LS1 to 55LS4 are selectively controlled so as to stop the supply (if the supply has already started).

According to the reference embodiment 4, the control device 56 supplies the main inverter circuit 56LM and the sub-inverter circuits 55LS1 to 55LS4 with a control signal according to the placement state of the object to be heated, thereby supplying the main heating coil MC and the sub-heating. The power supply to the coils SC1 to SC4 can be controlled independently of each other. In addition, by not driving the main heating coil MC in the center (turned off) and driving all the sub-heating coils SC1 to SC4 (turning on), the surface of the pan such as a frying pan (side surface of the pan). A cooking method such as preheating only) is also feasible.

In FIG. 21, 88 is a temperature sensor in which a temperature detecting element is installed in a space secured between an outer annular coil constituting the main heating coil MC and an inner annular coil. For example, it is a temperature sensor that detects infrared rays and detects temperature. This temperature sensor also constitutes a part of the heated object placement determination unit 86. That is, when an object to be heated such as the first cooking utensil 9 is placed on the left heating coil 8L and induction heating is started, if the object to be heated reaches a certain temperature or higher, it exists by this temperature sensor. Is detected.

In FIG. 23, 89 is a second storage chamber having an insertion port 90 in the front, similar to the storage chamber 21. The storage chamber 89 is not for storing cooking utensils such as pots. It is for accommodating the instruction manual and the like of the cooking device 1.

Reference numeral 30 is a plastic cover, which is a horizontally long rectangular shape when viewed from the front so that the insertion ports 22 and 90 of both of the two storage chambers 21 and 89 can be opened and closed at the same time.

In the reference embodiment 4, the first blower BM1 sucks the air outside the main body case 3 from a large number of suction holes (not shown) provided on the wall surface (rear surface plate 3H) on the back side of the main body case 3. Then, as shown by an arrow 91 in FIG. 23, the air after cooling the inverter circuit board 92 is supplied to the heating means 8 via the ventilation duct 74, although not shown, and finally the main body case 3 is provided. It is discharged from the exhaust port 6 (not shown) communicating with the rear exhaust side space 79B.

Reference numeral 93 is a furniture surface material for kitchen furniture. The thickness of the cover 30 and the position in the front-rear direction are managed so that the front surface 93F of the furniture surface material 93 and the cover 30 are arranged in a horizontal line when viewed from above. As a result, when the cover 30 is attached, the front positions are aligned.

The decorative plate 44 may be installed on the right side of the cover 30 as shown in Reference Form 1 without providing the second storage chamber 89.

As shown in FIG. 23, the first cooking utensil 9 has an elliptical inner bottom surface shape. The major axis dimension LS of the bottom surface is, for example, 280 mm. The maximum length of the first cooking utensil 9 including the handles 9D provided on both sides thereof is, for example, 320 mm. Therefore, it falls within the range of the depth dimension L2 (330 mm) of the storage chamber 21.

Further, as shown in FIG. 22, when the first cooking utensil 9 is heated by the right side heating coil 8R, the first cooking utensil 9 has an elliptical shape, and the major axis dimension LS of the bottom surface is 280 mm. Therefore, the right heating coil 8R with a maximum outer diameter DA3 of 200 mm is too small. That is, there is a concern that both ends of the first cooking utensil 9 cannot be sufficiently heated.

On the other hand, in the left side heating coil 8L, as described above, the diameter of the circle surrounding the outermost side of the four sub-heating coils SC1 to SC4 is, for example, 300 mm, and in the left side heating coil 8L, the diameter of the bottom surface is It can handle objects to be heated of about 320 to 350 mm.
As described above, the control device 56 supplies the control signal according to the placement state of the object to be heated to the main inverter circuit 56LM and the sub-inverter circuits 55LS1 to 55LS4. As shown in FIG. 21, when the first cooking utensil 9 is located on the main heating coil MC and the two sub-heating coils SC2 and SC3 on both sides of the main heating coil MC, the main inverter circuit 56LM and two Three inverter circuits of the sub-inverter circuits 55LS2 and 55LS3 are selected by the control device 56, and high frequency power is individually applied to them (simultaneously or with a time lag). As a result, for example, even when an elongated fish (for example, Pacific saury) is put in the first cooking utensil 9 and grilled, the entire bottom surface of the first cooking utensil 9 can be induced and heated, so that the whole fish can be heated. Can be heated.

As shown in FIG. 22, the left side heating coil 8L can also heat only the main heating coil MC, so that the left side heating coil 8L can handle various types of metal objects to be heated having different sizes and planar shapes. And even if it is the first cooking utensil 9 formed into an oval shape or a rectangular shape so that a long object to be cooked such as a saury can be cooked, the auxiliary heating required for driving corresponds to the size of the cooking utensil. Since the coils SC1 to SC4 can be automatically selected by the control device 56, the convenience of the user can be improved.

Further, even with such a long first cooking utensil 9, as shown in FIG. 23, the main body case 3 is continuously rearward from the insertion port 22 formed on the front surface of the main body case 3. Since the storage chamber 21 is formed inside, even a large first cooking utensil 9 can be stored.

Summary of Reference Form 4.
As is clear from the above description, also in the heating cooker 1 of the reference form 4, the cooling air from the first blower BM1 to the left side heating coil 8L is blown above the storage chamber 21 as in the reference form 1. , It is configured to pass through the space above the first partition wall 72.
Moreover, the left side heating coil 8L is configured to include four oval sub-heating coils SC1 to SC4 and a main heating coil MC. Therefore, when the sub-heating coils SC1 to SC4 and the main heating coil MC, which are supplied with electric power independently of the central coil, are co-heated, the range that can be heated becomes large. Moreover, when such a cooking utensil 9 is not used, it can be stored in the storage chamber 21, so that convenience can be enhanced both when it is used and when it is not used. Further, since a rectangular or elliptical object to be heated can be heated, a pot having a larger diameter than the conventional one, an iron plate for cooking, or the like can be used, and various kinds of cooking can be supported.
Since the effect of providing the storage chamber 21 can be expected to be the same as that of the reference embodiment 1, detailed description thereof will be omitted.

Reference form 5.
FIG. 24 shows a cooking device according to the reference embodiment 5 of the present invention. In this reference form 5, the form of the storage chamber 21 of the cooking cooker 1 is changed, and the left wall surface 21L, the right wall surface 21R, and the rear wall surface 21L, which divide the left and right sides of the storage chamber 21, leaving a support portion for supporting the saucer 26. A major feature is that the wall surface 21B and the upper wall surface 21T have been eliminated. The same or corresponding parts as those in FIGS. 1 to 15 may be designated by the same reference numerals, and duplicate description may be omitted.

In this reference form 5, 21 is a storage chamber, and there is no dedicated wall for this storage chamber 21, the left side uses the left wall surface of the body 3U of the main body case 3, and the right side uses the second partition wall 73. is doing. Further, as the ceiling surface, a part of the first partition wall 72 formed of a thin metal plate is used (also used).
Vents 95 are formed at a plurality of locations on the bottom surface of the body 3U of the main body case 3 that constitutes the bottom surface of the storage chamber 21 to communicate the inside and the outside of the storage chamber 21.

Reference numeral 26 denotes a saucer installed inside the storage chamber 21 so as to be movable in the front-rear direction, and the vertical walls 26L and 26R on both the left and right sides are supported by vertically standing metal support plates 94L and 94R. ing. The two support plates 94L and 94R are fixed to the upper surface of the body portion 3U of the main body case 3 by welding or the like.

Reference numeral 96 denotes a partition plate that is inserted from the insertion port 22 at a predetermined position inside the storage chamber 21 as needed, and when the partition plate 96 is installed, it is between the second partition wall 73 on the right side. In, another storage space 97 appears. That is, a space of about several cm of the gap SP2 is partitioned between the partition plate 96 and the second partition wall 73.

Reference form 6
FIG. 25 shows a cooking device according to the reference embodiment 6 of the present invention. In this reference form 6, similarly to the reference form 5, the form of the storage chamber 21 of the cooking cooker 1 is changed, and the left and right wall surfaces of the storage chamber 21 are eliminated while leaving a support portion for supporting the saucer 26. It is a big feature. The same or corresponding parts as those in FIGS. 1 to 15 may be designated by the same reference numerals, and duplicate description may be omitted.

In this reference form 6, the support structure of the saucer 26 is also changed. That is, the saucer 26 is located at the bottom of the storage chamber 21, and includes a pair of metal fixed rails 98 extending in the front-rear direction and a rolling element (roller) 99 that rolls in the fixed rails to move forward or backward. It is a configuration equipped with. The saucer 26 is supported by the rolling element 99 with a shaft (not shown).

The first partition wall 72 that partitions the inside of the main body case 3 into the upper space 70 and the lower space 71 does not reach the right side surface of the main body case 3 as in the reference form 1, and exists only halfway. However, the upper end portion (side surface) of the control box 58 of the cooling unit 57 is installed so as to come into contact with the right end portion of the first partition wall 72. One of the reference forms 6 is that the inside of the main body case 3 is substantially partitioned into two parts, an upper space 70 and a lower space 71, by the control box 58 and the first partition wall 72. It is a feature.

Reference numeral 21 is a storage chamber, and there is no dedicated wall for the storage chamber 21, the left side uses the left wall surface of the body 3U of the main body case 3, and the right side uses the second partition wall 73. Further, as the ceiling surface, a part of the first partition wall 72 formed of a thin metal plate is used (also used). This point is the same as the configuration of the reference form 5.

Further, also in this reference form 6, similarly to the reference form 5, when the partition plate 96 is inserted from the insertion port 22 into the inside of the storage chamber 21 as needed, it is between the second partition wall 73 on the right side. In addition, another storage space 97 can be secured, and small accessories, seasonings, foods, etc., which are different from the cooking utensils 9 and the like, can be stored in the storage space 97.

Summary of Reference Form 6.
As is clear from the above description, also in the heating cooker 1 of the reference form 6, the cooling air from the first blower BM1 to the left side heating coil 8L is above the storage chamber 21 as in the reference form 1. , It is configured to pass through the space above the first partition wall 72.
Moreover, in the reference embodiment 6, the wall surface itself constituting the ceiling surface of the storage chamber 21 is formed by the first partition wall 72, and cooling is performed along the upper surface of the first partition wall 72 before going to the left side heating coil 8L. As the wind flows, it will be directly cooled by the cooling air. Therefore, the effect of suppressing the temperature rise of the storage chamber 21 can be expected more effectively than that of the reference embodiment 1.

Further, since the first partition wall 72 that partitions the inside of the main body case 3 into the upper space 70 and the lower space 71 does not reach the right side surface of the main body case 3 and exists only halfway, the first partition wall is compared with the reference form 1. The area of 72 can be reduced, and the cost can be reduced. Since the effect of providing the storage chamber 21 can be expected to be the same as that of the reference embodiment 1, detailed description thereof will be omitted.

Reference form 7.
FIG. 26 shows a cooking device according to the reference embodiment 7 of the present invention. The major feature of the reference form 7 is that the reference form 6 is further improved and the air from the outside of the main body case 3 is taken into the inside of the storage chamber 21 by a dedicated blower. In the following description, the same or corresponding parts as those in FIGS. 1 to 15 may be designated by the same reference numerals, and duplicate description may be omitted.

In FIG. 26, the BM2 is a second blower installed in the lower part of the first space 71A, and is installed directly above the intake hole 101 formed on the bottom surface of the body portion 3U of the main body case 3. The second blower is an axial flow type blower installed so that the rotation axis of the fan is vertical, and is installed so as to supply the air sucked from below upward.

Reference numeral 102 is an air sterilizing means such as an ion generator or an ozone generator installed at a position on the downstream side of the second blower BM2. Reference numeral 103 is a guide plate installed at a position downstream of the second blower 100 with respect to the air sterilizing means. The air sterilizing means 102 and the guide plate 103 are attached to the surface of the second partition wall 73 on the first space 71A side.

Reference numeral 104 is an exhaust port provided in the first partition wall 72 constituting the ceiling surface of the storage chamber 21. This exhaust port is formed in the left inner part of the storage chamber farthest from the second blower BM2. Reference numeral 105 is a horizontally elongated groove provided in the pair of support plates 94L and 94R, respectively, and 106 is a support pin horizontally fixed on both left and right sides of the saucer 26, and this pin is the groove 105. It is passed through. Therefore, if the user pulls the saucer 26 to pull it out toward the insertion slot 22, the pin 106 of the saucer 26 is supported by the groove 105 and slides forward, so that the user can manually handle the weight of the saucer 26. You can easily pull it forward without supporting it.

26R is the right vertical wall of the saucer 26, and 26L is the left vertical wall of the saucer 26. As shown in FIG. 26, the entire saucer 26 has a shape in which a large number of through holes 26F are formed in the left and right vertical walls 26L and 26R. That is, the entire saucer is integrally molded of plastic or the like, and a large number of through holes 26F are formed around the saucer to enhance air permeability, so that the shape is like a tableware basket. The exhaust port 104 is provided with an activated carbon filter, a catalyst for removing ozone, and the like in order to enhance the air germs and deodorizing effect in combination with an air sterilizing means 102 such as an ion generator or an ozone generator. May be. If such a filter or catalyst is provided, it is advisable to devise an installation structure so that it can be replaced from the insertion slot 22.

In the reference embodiment 7 shown in FIG. 26, the right wall surface that substantially determines the storage volume of the storage chamber 21 is the right vertical wall 26R in which a large number of through holes 26F are formed. A second gap SP2 of about several cm to 10 cm is formed between the right vertical wall 26R and the second partition wall 73. The second blower BM2 is arranged near the bottom of the second gap SP2.

In this reference form 7, the partition plate 38 and the partition plate 39 as described in the reference form 3 (FIG. 20) are not installed. Since the second blower BM2 is installed as a dedicated blower for the storage chamber 21, the air discharged from the storage chamber 21 and the air blown out from the first blower BM1 for cooling the heating means 8. This is because the air does not mix in front of the partition wall 77. If the pressures of the air discharged from the storage chamber 21 and the air blown out from the first blower BM1 for cooling the heating means 8 are not equal at the position of the exhaust port 104, for example, the first blower BM1 side. If the air pressure from the air is high, there is a concern that the air will flow into the exhaust port 104 (backflow). The partition plate 38 and the partition plate 39 as described in FIG. 20) may be installed.

Even the front of the space between the second partition wall 73 and the right vertical wall 26R is covered by the right cover 44 fixed to the main body case 3. The entire front surface on the left side of the right cover is covered with the cover 30 so as to be openable and closable. Therefore, the width dimension W1 of the cover 30 is narrower than that of the reference embodiment 1. The right cover 44 is configured to be removable by a professional repair company or the like in order to enable inspection of the blower BM2.

Summary of Reference Form 7.
As is clear from the above description, the following invention has been carried out in the cooking device 1 of the reference embodiment 7.
That is, the cooking cooker of FIG. 26 has a main body case 3 supported by kitchen furniture and a main body case 3.
A first partition wall 72 (in the horizontal direction) that divides the inside of the main body case 3 into two spaces, an upper space 70 and a lower space 71, and
A second partition wall 73 for partitioning the lower space 71 into a first space 71A and a second space 71B (in the vertical direction) is provided.
Inside the first space 71A, a storage chamber 21 leading to the outside of the main body case 3 is formed via an insertion port 22 formed on the front surface of the main body case 3.
In the upper space 70, a heating means 8 for inducing and heating the objects to be heated 9, 10 and 11 placed on the top plate 4 constituting the upper surface of the main body case 3 is arranged.
A cover 30 for opening and closing the insertion port 22 is provided on the front side of the insertion port 22.
In the second space 71B, an inverter circuit board 55 on which the circuit element 59 for the power supply circuit of the heating means 8 is mounted, and cooling air sucked from the outside of the main body case 3 while the heating means 8 is being driven. A first blower BM1 supplied for cooling the circuit element 59 is built in, and the first space 71A is cooled by passing from the outside of the main body case 3 to the outside or inside of the storage chamber 21. It is a configuration in which a second blower BM2 for introducing wind is arranged.

That is, if the cooling air passage from the intake side space 79A to the heating means 8 via the first blower BM1 and the cooling unit 57 is referred to as a "first intake air passage", in this reference embodiment, the first It is provided with a "second intake air passage" having a path different from that of the intake air passage. That is, the second intake air passage is an air passage from the intake hole 101 to the storage chamber 21 via the second blower BM2.

Because of this configuration, in the heating cooker 1 of the reference embodiment 7, the cooling air from the first blower BM1 to the left side heating coil 8L flows above the storage chamber 21 and above the space above the first partition wall 72. It is a structure that passes through.
Further, the air introduced from the second blower BM2 is forcibly supplied to the inside of the storage chamber 21 and discharged to the upper space 70 above the first partition wall 72.

Therefore, in the cooking device 1 of the reference embodiment 7, hot air is less likely to stay inside the storage chamber 21, and the inside of the storage chamber 21 is prevented from becoming overheated.

Moreover, in this reference embodiment 7, the wall surface itself constituting the ceiling surface of the storage chamber 21 is formed by the first partition wall 72, and cooling is performed along the upper surface of the first partition wall 72 before going to the left side heating coil 8L. Since the wind flows, the cooling air directly cools the first partition wall 72 as well. Therefore, the effect of suppressing the temperature rise of the storage chamber 21 can be expected more effectively than that of the reference embodiment 1.

Further, in the reference embodiment 7, when the air sterilizing means 102 such as an ion generator or an ozone generator installed at a position downstream of the second blower BM2 is driven, various germs in the air are sterilized. Therefore, the internal atmosphere of the storage chamber 21 can be cleaned. Therefore, it is possible to suppress the generation of foul odors and molds for a long period of time, and it is possible to maintain a clean storage space.

The guide plate 103 is for directing the flow of cooling air immediately after being sucked from the second blower BM2 toward the storage chamber 21, and is not an essential component.

The first blower BM1 started operation at the same time as driving the heating means 8, but the second blower BM2 does not need to start operation at the same time as driving the heating means 8. The second blower BM2 may start operation when the temperature inside the storage chamber 21 rises, and such control is performed by providing a temperature sensor for detecting the temperature inside the storage chamber 21 and the temperature sensor. The temperature detection data may be configured to be input to the temperature detection circuit 63. With this configuration, the control device 56 that controls the start and stop of the operation of the second blower BM2, the operation speed, and the like automatically controls the operation of the second blower BM2. Since the blowing capacity of the second blower BM2 is much smaller than the blowing capacity of the first blower BM1, the power consumption is also low.

Further, in the reference form 7, a storage chamber 21 is secured inside the main body case 3, and accessories, first cooking utensils 9, second cooking utensils 10, and the like are secured in the storage chamber 21 from the insertion port 22. Items can be inserted and stored, and can be taken out as needed. Moreover, as shown in FIG. 26, the saucer 26 in the storage chamber 21 has a basket shape in which a large number of through holes 26F are formed so as to be suitable for air flow as a whole. The air supplied from the blower BM2 of 2 is easy to circulate, and negative ions and ozone are distributed throughout the saucer 26. Therefore, the effect of deodorizing and germs in the internal air of the storage chamber 21 is enhanced.

The cooling air passage of the first intake air passage from the intake side space 79A to the heating means 8 via the first blower BM1 and the cooling unit 57 contributes to the cooling of the heating means 8. The cooling air supplied from the intake hole 101 to the storage chamber 21 via the second blower BM2 and from there to the upper space 70 is not expected to cool the heating means 8, so that the exhaust port 104 May be discharged directly to the outside of the main body case 3.

Modification example of reference form 7.
27 and 28 show a cooking device according to a modified example of the reference embodiment 7 of the present invention. The major feature of this modification is that the position of the second blower BM2 of the reference form 7 is changed, and the air from the outside of the main body case 3 is taken into the inside of the storage chamber 21 by a dedicated blower. In the following description, the same or corresponding parts as those in FIGS. 1 to 15 may be designated by the same reference numerals, and duplicate description may be omitted.

In FIG. 27, 94R is a metal support plate erected in the first space 71A, and an air introduction port 107 is opened at the upper end thereof. The second blower BM2 is attached to the support plate 94R on the right side corresponding to the introduction port 107. As shown in FIG. 27, the second blower BM2 is installed on the front-rear direction center line CL2, and is arranged in the front-rear direction center portion of the storage chamber 21.

The second partition wall 73 divides the lower space 71 into the first space 71A and the second space 71B. In particular, in this modification, as in the reference embodiment 7, the air outside the main body case 3 is sucked from the intake hole 101 provided immediately to the lower left of the second partition wall 73, so that the section of the second partition wall 73 is divided. If it is insufficient, air will be sucked from the second space 71B. Alternatively, a part of the air sent to the ventilation duct 74 flows in. Therefore, the second partition wall 73 is ideally in a form of maintaining the airtightness of the peripheral edge by using a sealing material such as packing, but unless a large amount of air is attracted from the second space 71B, the main body case 3 A small gap between and is allowed.

Even the front of the space between the second partition wall 73 and the support plate 94R is covered by the right cover 44 fixed to the main body case 3. The entire front surface on the left side of the right cover is covered with the cover 30 so as to be openable and closable. Therefore, the width dimension W1 of the cover 30 is narrower than that of the reference embodiment 1. The right cover 44 is configured to be removable by a professional repair company or the like in order to enable inspection of the blower BM2.

FIG. 28 is a vertical cross-sectional view of the central portion when cut along the center line CL2 in the front-rear direction of FIG. 27.
Reference numeral 104 is an exhaust port provided in the first partition wall 72 constituting the ceiling surface of the storage chamber 21. As is clear from FIG. 27, the exhaust port 104 is located on the opposite side of the second blower BM2 with the left and right center points (XO) of the storage chamber 21 interposed therebetween.

As is clear from the above description, also in the heating cooker 1 of the modified example of the reference form 7, hot air is less likely to stay inside the storage chamber 21 as in the reference form 7, and the inside of the storage chamber 21 is less likely to stay. Is prevented from becoming overheated. However, since this modification does not include the air sterilizing means 102 such as an ion generator or an ozone generator, it does not have the air sterilizing effect as in Reference Form 7.

As shown in FIG. 27, when viewed from the second blower BM2, the exhaust port 104 for exhausting the air inside the storage chamber 21 sandwiches the left and right center points (XO) of the storage chamber 21. Since it is located on the opposite side of the second blower BM2, the cooling air blown from the second blower BM2 efficiently flows from the right side to the left side of the storage chamber 21. Moreover, since the left and right vertical walls 26L and 26R of the storage chamber 21 have a large number of through holes 26F, the air inside the storage chamber 21 can easily flow. For these reasons, there is an effect that the phenomenon that hot air stays in a part of the inside of the storage chamber 21 can be eliminated.

Further, since the front of the space between the second partition wall 73 and the support plate 94R is also covered by the right cover 44 fixed to the main body case 3, the user accidentally puts a hand or a foreign object in the space on the right side of the support plate 94R. There is no concern about inserting. Further, since the blower BM2 itself cannot be seen from the front side of the cooking cooker 1, there is an advantage that the aesthetic appearance is not spoiled.

Reference form 8.
FIG. 29 shows a cooking device according to the reference embodiment 8 of the present invention. The major feature of this reference form 8 is that the reference form 1 is further improved, a dedicated second blower is installed outside the storage chamber 21, and the air from the outside of the main body case 3 is taken in by the blower. .. In the following description, the same or corresponding parts as those in FIGS. 1 to 15 may be designated by the same reference numerals, and duplicate description may be omitted.

In FIG. 29, 104 is an exhaust port provided in the first partition wall 72 constituting the ceiling surface of the storage chamber 21. The BM2 is a second blower, and is installed on the upper surface of the first partition wall 72 at a position directly above the exhaust port 104. Reference numeral 105 is a horizontally elongated groove provided in the pair of left and right support plates 94L and 94R, respectively, and 106 is a support pin horizontally fixed on both the left and right sides of the saucer 26, and this pin is the groove. It is passed through 105.

The lower ends of the two support plates 94L and 94R are fixed to the bottom surface 3B of the main body case 3, respectively. The upper end surfaces of the support plates 94L and 94R do not reach the lower surface of the first partition wall 72, and an interval of about several cm is maintained. The interval is intended to facilitate the flow of air.

Intake holes 108 are formed at a plurality of locations on the bottom surface of the body 3U of the main body case 3 that constitutes the bottom surface of the storage chamber 21 to communicate the inside and the outside of the storage chamber 21. When the second blower BM2 is operated, fresh air outside the main body case 3 is introduced from the intake hole 108 as shown by the broken line arrow in FIG. 29. Then, it passes through the storage chamber 21 and is finally sucked into the second blower BM2 from the exhaust port 104 and discharged to the upper space 70.

Reference numeral 109 denotes a shelf supported by the main body case 3 like the saucer 26, and a large number of openings 110 are formed throughout the shelf, and the air permeability is good. Although this shelf is supported by the main body case 3 like the saucer 26, only this shelf 109 can be removed when it is pulled out from the insertion slot 22. Can be placed on the tray 26 with the large cooking utensil 9 or the like removed. It should be noted that the shelf 109 is not always necessary, and it is possible to accommodate only the saucer 26 in the storage chamber 21 without using it.

Further, since the shelf 109 has a large number of openings 110 formed throughout and has good ventilation, even if the tableware or cooking utensils immediately after washing are placed on the shelf 109 and stored in the storage chamber 21. good.

The cover 30 has a width dimension W1 that covers the entire front of the space up to the support plate 94R forming the right side surface of the storage chamber 21 and the second partition wall 73. A right cover 44 (not shown in FIG. 29) is fixed to the front plate 3F of the main body case 3 so as to be adjacent to the right side of the cover 30.

Summary of Reference Form 8.

The storage chamber 21 is covered above with a first partition wall 72 extending in the horizontal direction, and a second partition wall 73 extending in the vertical direction is arranged on the right side with a predetermined gap SP2.
The storage chamber leads to the outside of the main body case 3 via an insertion port 22 formed on the front surface of the main body case 3.
The insertion port 22 has a cover 30 that is opened and closed by the user.
In the space above the first partition wall 72, a heating means 8 for inducing and heating the objects to be heated 9, 10 and 11 placed on the top plate 4 constituting the upper surface of the main body case 3 is arranged.
In the space opposite to the storage chamber 21 with the second partition wall 73 interposed therebetween, the inverter circuit board 55 for the power supply circuit of the heating means 8 and the outside of the main body case 3 while the heating means 8 is being driven. A first blower BM1 that supplies the sucked cooling air for cooling the electric component is arranged.
The storage chamber 21 has a configuration in which the upper wall surface 21T constituting the ceiling surface is arranged with a distance H2 of 5 cm or more from the lower surface of the heating means 8 (8L).
In the heating cooker of the present invention, even if the upper wall surface 21T of the storage chamber 21 is made of magnetic metal, the upper wall surface 21T is magnetically affected by the left side heating coil 8L installed above. There is almost no such thing, and the influence that the upper wall surface 21T itself is induced and heated can be eliminated. Further, the right wall surface 21R of the storage chamber 21 also has a second partition wall 73 and a predetermined gap SP2 sandwiched between the space where the inverter circuit board 55 is arranged on the right side thereof, so that the heat is thermally from the right side. It is also avoided to be affected. As a result, the temperature rise in the internal space of the storage chamber 21 is suppressed.

Further, in the reference embodiment 9, the cooling air introduced from the outside of the main body case 3 is passed around the storage chamber 21 without passing through the heating means 8, and the first storage chamber 21 is above the storage chamber 21. It is a configuration that discharges above the partition wall 72 of the above.
Because of this configuration, in the heating cooker of the reference form 9, a storage chamber 21 is secured inside the main body case 3, and articles such as accessories and cooking utensils 9 are placed in the storage chamber 21 from the insertion slot 22. It can be inserted and stored, and can be taken out as needed. Moreover, it can be expected that the cooling air of the second blower BM2 for cooling the storage chamber 21 suppresses the temperature rise of the internal space of the storage chamber 21.

Embodiment 1.
31 and 32 show the cooking apparatus according to the first embodiment of the present invention. In the first embodiment, the reference embodiment 1 is further improved, a dedicated second blower BM2 is installed outside the storage chamber 21, and the air from the outside of the main body case 3 is taken in by the blower, and the storage chamber 21 is taken in. It is a major feature that the air cooled by the air is finally discharged from the lower space 71 to the outside of the main body case 3. In the following description, the same or corresponding parts as those in FIGS. 1 to 15 may be designated by the same reference numerals, and duplicate description may be omitted.

In FIGS. 31 and 32, the BM2 is a second blower and is a multi-blade blower (sirocco fan). This blower is supported on the lower surface of the first partition wall 72 (see FIG. 32). 112 is a suction port formed on the right side surface of the blower BM2, and 113 is a blow port. This outlet is directed toward the gap SP1 between the ceiling surface of the storage chamber 21 and the first partition wall 72.

In FIGS. 31 and 32, 111 is an exhaust hole (exhaust port) formed in the front plate 3F of the main body case 3, and a plurality of the exhaust holes (exhaust ports) are provided side by side. The position of the exhaust hole 111 is immediately below the first partition wall 72. In FIG. 32, the exhaust hole 111 and the outlet 113 of the second blower BM2 are drawn so as to face each other, but in reality, as shown in FIG. 31, the storage chamber It is located opposite to each other across the left and right center points XO.

In FIG. 32, 114 is an intake port formed in the inclined surface portion 3J of the main body case 3, and is composed of a large number of small holes. This intake port serves as an inlet for air introduced by the second blower BM2. The intake port may be formed on the rear surface plate 3H, or may be formed on both the inclined surface portion 3J and the rear surface plate 3H. The second blower BM2 is located on the right side of the left and right centers of the storage chamber 21 when viewed from the cover 30 side, but may be provided at a position other than this position. For example, it may be provided on the left side of the center of the left and right sides of the storage chamber 21. Further, in order to prevent the cooling air blown from the outlet 113 of the second blower BM2 from being inadvertently diffused in the lateral direction, air is provided on the ceiling surface of the storage chamber 21 from the outlet 113 side to the vicinity of the exhaust hole 111. A plurality of partition plates for guiding the above may be provided side by side. That is, it is further preferable to design the air passage so that the wind from the second blower BM2 smoothly flows over a wide range of the ceiling surface of the storage chamber 21.

With the above configuration, when the second blower BM2 is operated, as shown by the solid arrow in FIG. 32, the flow of cooling air is first shown from the gap GPU to the outside air of the main body case 3. Is sucked and introduced into the main body case 3. That is, fresh air in the kitchen or the like is sucked from the outside of the kitchen furniture 2.

Then, the cooling air introduced from the intake port 114 enters the second blower BM2 from the suction port 112, and is blown forward from the outlet 113. The blown air moves forward in the void SP1 above the storage chamber 21, as shown by the dashed arrow in FIG. 28, the flow of the cooling air.

Finally, the cooling air is discharged to the front of the kitchen furniture 2 from a large number of exhaust holes 111 which are exhaust ports of the lower space 71. It should be noted that the reason why a large number of exhaust holes 111 are provided is that there may be a user on the front side of the kitchen furniture 2, and there is a concern that the user may feel uncomfortable if the exhaust is concentrated from one place. Therefore, if the exhaust is dispersed as in the first embodiment, the exhaust flow can be weak enough not to be noticed by the user.

With this configuration, the storage chamber 21 is cooled by the cooling air flow flowing through the outside, particularly the ceiling surface, so that the inside of the storage chamber 21 is prevented from becoming overheated.

Summary of Embodiment 1.
As is clear from the above description, the present invention has been carried out in the cooking device 1 of the first embodiment.
That is, the cooking utensils 1 in FIGS. 31 and 32 are
The main body case 3 supported by the kitchen furniture 2 and
A first partition wall 72 (in the horizontal direction) that divides the inside of the main body case 3 into two spaces, an upper space 70 and a lower space 71, and
A second partition wall 73 for partitioning the lower space 71 into a first space 71A and a second space 71B (in the vertical direction) is provided.
A storage chamber 21 that leads to the outside of the main body case 3 is formed in the first space interior 71A via an insertion port 22 formed on the front surface of the main body case 3.
In the upper space 70, a heating means 8 for heating an object to be heated placed on a top plate 4 constituting the upper surface of the main body case is arranged.
A cover 30 for opening and closing the insertion port 22 is provided on the front side of the insertion port 22.
In the second space 71B, the inverter circuit board 55 on which the electric component (circuit element) 59 for the power supply circuit of the heating means 8 is mounted, and the heating means 8 are sucked from the outside of the main body case 3 while being driven. A first blower BM1 that supplies cooling air for cooling the circuit element is built-in.
The upper space 70 has an exhaust port 6 for discharging the cooling air of the first blower BM1 via the heating means 8.
The lower space 71 is provided with a second blower BM2 for introducing cooling air passing from the outside of the main body case 3 to the outside or inside of the storage chamber 21, and an exhaust port 111 for the blower, respectively. It is a configuration.
In the heating cooker 1 of the present invention, a storage chamber 21 is secured inside the main body case 3, and accessories and articles such as cooking utensils 9, 10, 11 are inserted into the storage chamber 21 from the insertion port 22. It can be stored and taken out as needed. Moreover, in the lower space 71 where the storage chamber 21 is located, a second blower BM2 that introduces cooling air to the outside of the storage chamber 21 and an exhaust port 111 for this blower are provided, respectively, so that the main body case 3 In the lower space 71 of the above, a cooling air passage through which the cooling air flows is formed outside the storage chamber 21 independently of the cooling air passage of the upper space 70. As a result, the temperature rise in the internal space of the storage chamber 21 is suppressed.

As shown in FIG. 32, if the space for installing the second blower BM2 is used behind the storage room 21, a large installation space can be secured. The reason for this will be described below.
The storage chamber 21 is preferably as large as possible for the purpose of storing a large number of articles. However, as described in Reference Form 1, since there is an inclined surface portion 3J at the rear of the main body case 3 in order to install it in the kitchen furniture 2 like this cooking cooker 1, the depth dimension of the storage chamber 21 is large. Be constrained. That is, as shown in FIG. 32, the back surface of the storage chamber 21 is designed to be at a position immediately before the inclined surface portion 3J so as not to interfere with the inclined surface portion 3J. Therefore, behind the storage chamber 21, a space is created above the inclined surface portion 31J (according to the depth dimension of the inclined surface portion 31J). Therefore, if the second blower BM2 such as a multi-blade blower (sirocco fan) is arranged in this space, the internal space of the main body case 3 can be effectively used. Therefore, even if there is a certain restriction on the internal space dimension of the main body case 3 due to the standard of the kitchen furniture 2, if the second blower BM2 is arranged above the inclined surface portion 3J as described above, it is above the storage chamber 21. It is possible to obtain an air passage structure that effectively cools the void SP1.

Modification example of the first embodiment 1.
FIG. 33 shows a cooking device according to a modification 1 of the first embodiment of the present invention. In this modification 1, the intake path of the second blower BM2 of the first embodiment is increased so that the intake flow of the second blower BM2 flows both inside and outside the storage chamber 21. In the following description, the same or corresponding parts as those in FIGS. 1 to 15 may be designated by the same reference numerals, and duplicate description may be omitted.

In FIG. 33, 104 is an exhaust port formed on the upper portion of the rear wall surface (rear surface) 21B of the storage chamber 21. Reference numeral 115 denotes a guide plate provided immediately below the vicinity of the exhaust port 104 and guiding the flow of the air flow. This guide plate is attached to the outside of the rear wall surface (rear surface) 21B of the storage chamber 21. The second blower BM2 is installed above the guide plate 115. Since the other configurations are the same as those of the first embodiment of FIGS. 31 and 32, the description thereof will be omitted.

With the above configuration, when the second blower BM2 is operated, first, as shown by the solid arrow in FIG. 33, the air flow from the gap GPU to the outside of the main body case 3 is shown. Is sucked and introduced into the main body case 3. That is, fresh air in the kitchen or the like is sucked from the outside of the kitchen furniture 2.

On the other hand, since there is a gap between the storage chamber 21 and the cover 30, when the second blower BM2 is operated, the storage chamber 21 is operated via the exhaust port 104 near the suction port 112 of the blower. The internal air pressure drops. Therefore, as shown by the arrow FF in FIG. 33, the flow of the attracted air is introduced from the gap between the storage chamber 21 and the cover 30, and the fresh air outside the main body case 3 is introduced into the storage chamber. After passing through 21 from the lower side to the upper side, the air is discharged from the exhaust port 104.

Then, the air introduced into the suction port 112 from the intake port 114 and the exhaust port 104 is blown forward from the outlet 113. The blown air moves forward in the gap SP1 above the storage chamber 21, and is finally discharged to the front of the kitchen furniture 2 from a large number of exhaust holes 111 which are exhaust ports of the lower space 71. It should be noted that the reason why a large number of exhaust holes 111 are provided is that there may be a user on the front side of the kitchen furniture 2, and there is a concern that the user may feel uncomfortable if the exhaust is concentrated from one place. Is. This point is as already described in the first embodiment.

Summary of modification 1 of the first embodiment.
As is clear from the above description, the present invention is carried out in the first modification of the first embodiment.
That is, the cooker 1 in FIG. 33 has a main body case 3 supported by the kitchen furniture 2 and a main body case 3.
A first partition wall 72 (in the horizontal direction) that divides the inside of the main body case 3 into two spaces, an upper space 70 and a lower space 71, and
A second partition wall 73 for partitioning the lower space 71 into a first space 71A and a second space 71B (in the vertical direction) is provided.
A storage chamber 21 that leads to the outside of the main body case 3 is formed in the first space interior 71A via an insertion port 22 formed on the front surface of the main body case 3.
In the upper space 70, a heating means 8 for heating an object to be heated placed on a top plate (top plate) 4 constituting the upper surface of the main body case is arranged.

It can be stored and taken out as needed. Moreover, in the lower space 71 where the storage chamber 21 is located, a second blower BM2 that introduces cooling air flowing both inside and outside the storage chamber 21 and an exhaust port 111 for this blower are provided, respectively. Therefore, in the lower space 71 of the main body case 3, the cooling air flows to the outside of the storage chamber 21 independently of the cooling air passage of the upper space 70, and another cooling air also flows into the storage chamber 21. As a result, the temperature rise in the internal space of the storage chamber 21 is suppressed.

Modification example of the first embodiment 2.
34 and 35 show the cooking apparatus according to the second modification of the first embodiment of the present invention. In this modification 2, the intake path of the second blower BM2 of the first embodiment is increased so that the intake flow of the second blower BM2 flows both inside and outside the storage chamber 21. In the following description, the same or corresponding parts as those in FIGS. 1 to 15 may be designated by the same reference numerals, and duplicate description may be omitted.

In FIGS. 34 and 35, 104 is an exhaust port formed on the rear wall surface 21B of the storage chamber 21. Reference numeral 111 is an exhaust hole for the same purpose as the exhaust hole 111 shown in FIG. 33.
The second blower BM2 is, for example, a so-called axial flow type blower with a built-in motor, and is installed above the exhaust port 104. In addition, another fan type blower such as a multi-blade type may be used.

Reference numeral 116 denotes an exhaust port provided at the frontmost position of the upper space 70, which is formed on the upper portion of the front plate 3F of the main body case 3. It should be noted that this exhaust port may be formed by arranging a large number of small holes instead of one large hole. This enables distributed exhaust. Further, the exhaust port 116 may be formed so as to be dispersed to the left and right while avoiding the center of the front surface in consideration of the fact that the user is on the front side of the kitchen furniture 2.

Reference numerals 117 are ventilation holes formed in the bottom surface portion 3B of the main body case 3, and are scattered at a plurality of separated locations. Reference numeral 118 is a plurality of storage chamber ventilation holes located directly above the ventilation holes, and are formed on the bottom wall surface 21U of the storage chamber 21.

Reference numerals 119 are ventilation holes formed on the bottom surface of the saucer 26, and are formed at positions corresponding to the storage chamber ventilation holes 118, respectively.
Reference numeral 120 denotes a guide plate provided immediately above in the vicinity of the second blower BM2 and guiding the flow of the blown air flow to the front side. This guide plate is attached to the underside of the first partition wall 72. Although not shown, a duct or another guide plate for allowing air to flow in a wide range is installed in the gap SP1 above the storage chamber 21 on the downstream side of the exhaust flow of the second blower BM2. You may. Since the other configurations are the same as those shown in FIG. 30, the description thereof will be omitted.

Reference numeral 129L is a partition wall provided on the first partition wall 72 along the center line CL2 in the front-rear direction, and has a rib shape. The partition wall may be integrally formed with the first partition wall 72, or may be formed separately from the first partition wall 72, and may be fixed to the upper surface of the first partition wall 72. 129R is a similar partition wall. The uppermost portions of both of these two partition walls 129L and 129M are in close contact with or close to the lower surface of the top plate 4.

With the above configuration, when the second blower BM2 is operated, the air flow from the gap GPU to the outside of the main body case 3 is first shown by the solid arrow in FIG. 35. Is sucked and introduced into the main body case 3. That is, fresh air in the kitchen or the like is sucked from the outside of the kitchen furniture 2.

On the other hand, the air outside the main body case 3 is attracted into the storage chamber 21 from the ventilation hole 117 via the storage chamber ventilation hole 118 and further through the ventilation hole 119. That is, when the second blower BM2 is operated, the air pressure inside the storage chamber 21 drops through the exhaust port 104 near the suction port 112 of the blower. Therefore, as shown by the solid line arrow FG in FIG. 35, the flow of the attracted air is introduced from the outside of the main body case 3, passes through the storage chamber 21, and then discharged from the exhaust port 104. ..

Then, the air introduced into the suction port 112 from the intake port 114 and the exhaust port 104 is blown forward from the outlet 113. The blown air moves forward in the gap SP1 above the storage chamber 21 as shown by the broken line arrow in FIG. 34, and finally from a large number of exhaust holes 111 which are exhaust ports of the lower space 71. It is released to the front of the kitchen furniture 2. It should be noted that the reason why a large number of exhaust holes 111 are provided is that there may be a user on the front side of the kitchen furniture 2, and there is a concern that the user may feel uncomfortable if the exhaust is concentrated from one place. Is. This point is as already described in the first embodiment.

On the other hand, inside the upper space 70, the upper part of the first partition wall 72 is divided into front and rear from the right side heating coil 8R by the partition walls 129L and 129M provided along the front-rear direction center line CL2. It has become.

Therefore, the cooling air after cooling the right side heating coil 8R and the cooling air after cooling the central heating coil 8M and the left side heating coil 8L are divided into two by the partition wall 129L and 129M. Then, the cooling air flowing behind the partition walls 129L and 129M goes to the rear exhaust side space 79B as shown by the solid arrow 54B in FIG. 34.

On the other hand, the cooling air flowing in front of the partition walls 129L and 129M goes toward the front exhaust port 116 as shown by the solid arrow 54F in FIG. 34.

By the way, in this modification 2, the exhaust port 116 is located near the exhaust hole 111. The air exhausted from the exhaust port 116 takes away the heat of the heating means 8 that becomes hot for cooking and the top plate 4 that receives the heat, and is discharged from the lower space 71 through the exhaust hole 111. The temperature is higher than that of the air. However, in this modification in which the exhaust port 111 is arranged immediately below the exhaust port 116, the low temperature air from the exhaust hole 111 is mixed with the exhaust from the exhaust port 116, which has the effect of lowering the overall temperature. .. Therefore, due to the synergistic effect of the distributed exhaust, hot warm air is not concentrated only at a specific position on the front side of the kitchen furniture 2, and the user feels uncomfortable or anxious. There is no.

In FIG. 34, an exhaust port 6 is provided on the rear side of the main body case 3, and the heat of the heating means 8 and the top plate 4 that receives the heat is taken from the exhaust port 6 to exhaust the high temperature. However, as described above, since it is possible to lower the temperature of the entire exhaust by mixing it with the low-temperature air exhausted from the exhaust port 116 and exhausting the air, the above-mentioned exhaust port 6 is abolished. However, the exhaust of the upper space 70 may not be exhausted from the upper surface of the heating cooker 1 at all. By doing so, the appearance of the upper surface of the heating cooker 1 becomes a flat design having neither an intake port nor an exhaust port, and not only the cleanability is improved, but also the design of the appearance is improved.

Summary of modified example 2 of the first embodiment.
As is clear from the above description, the present invention has been carried out in the second modification of the first embodiment.
That is, the cooker 1 of FIGS. 34 and 35 has a main body case 3 supported by the kitchen furniture 2 and a main body case 3.
A first partition wall 72 (in the horizontal direction) that divides the inside of the main body case 3 into two spaces, an upper space 70 and a lower space 71, and
A second partition wall 73 for partitioning the lower space 71 into a first space 71A and a second space 71B (in the vertical direction) is provided.
A storage chamber 21 that leads to the outside of the main body case 3 is formed in the first space interior 71A via an insertion port 22 formed on the front surface of the main body case 3.
In the upper space 70, a heating means 8 for heating an object to be heated placed on a top plate 4 constituting the upper surface of the main body case is arranged.
A cover 30 for opening and closing the insertion port 22 is provided on the front side of the insertion port 22.
In the second space 71B, the inverter circuit board 55 on which the electric component (circuit element) 59 for the power supply circuit of the heating means 8 is mounted, and the heating means 8 are sucked from the outside of the main body case 3 while being driven. A first blower BM1 that supplies cooling air for cooling the circuit element is built-in.
The upper space 70 has exhaust ports 6 and 116 for discharging the cooling air of the first blower BM1 via the heating means 8.
In the lower space 71, a ventilation hole 117 of the main body case 3, a ventilation hole 117 of the storage chamber 21, and cooling air passing through both the outside and the inside of the storage chamber 21 from the outside of the main body case 3 are introduced. The second blower BM2 and the exhaust port 111 formed for passing the air for the blower are provided.
In the heating cooker 1 of the second modification, a storage chamber 21 is secured inside the main body case 3, and accessories and articles such as cooking utensils 9, 10 and 11 are inserted into the storage chamber 21 from the insertion port 22. Can be stored and taken out as needed. Moreover, in the lower space 71 where the storage chamber 21 is located, a second blower BM2 that introduces cooling air flowing both inside and outside the storage chamber 21 and an exhaust port 111 for this blower are provided, respectively. Therefore, in the lower space 71 of the main body case 3, the cooling air flows to the outside of the storage chamber 21 independently of the cooling air passage of the upper space 70, and another cooling air also flows into the storage chamber 21. As a result, the temperature rise in the internal space of the storage chamber 21 is suppressed.

Reference form 10.
36 and 37 show the cooking cooker according to the reference embodiment 10. This reference form is characterized in that the storage chamber 21 of the cooking device 1 is further positively cooled, and the supply of cooling air to the storage chamber is controlled. The same or corresponding parts as those in FIGS. 1 to 15 may be designated by the same reference numerals, and duplicate description may be omitted.

FIG. 36 is a plan view of the cooking cooker shown in a state where the top plate and the rear frame plate are removed, as in FIG. In the cooking device 1 of the reference embodiment 10, a branch duct 84 is used between the control box 58 of the cooling unit 57 and the storage chamber 21 in the second space 71B, as in the case of the one shown in FIG. One of the features is that they are connected. FIG. 37 is a block diagram showing a main control-related portion of the cooking cooker shown in FIG. 36.

One end (upstream side) of the branch duct 84 is connected to the left side surface of the control box 58, and the other end (downstream side) is connected to the upper part of the right wall surface 21R of the storage chamber 21. As a result, a part of the cooling air supplied from the first blower BM1 to the inside of the cooling unit 57 branches at the stage reaching the rear part of the inverter circuit board 55 and flows into the branch duct 84.

The cooling air flowing into the branch duct 84 is introduced into the storage chamber 21 from the end of the branch duct 84, passes through the storage chamber 21, and then passes through the ceiling portion (upper wall surface 21T) of the storage chamber 21. It is discharged to the upper space 70 from an exhaust duct 85 (not shown, see FIG. 20) provided so as to penetrate. The cooling air discharged from the air duct 74 also flows into the upper space 70, but the air discharged from the air duct 74 is discharged from the control box 58 via the air duct 74 having a long path. Therefore, the pressure is low, and this air does not flow back through the exhaust duct 85 and enter the storage chamber 21.

In FIG. 36, 127 is an air passage opening / closing means such as an electromagnetic opening / closing valve or a shutter provided in the middle of the branch duct 84. When a predetermined electric signal is transmitted from the drive circuit 128 (see FIG. 37), the internal air passage of the branch duct 84 is opened. When the electric signal is not output, the internal air passage is automatically closed by the force of a spring or the like. This is one of the major features of this embodiment.

In FIG. 37, 128 is a drive circuit for driving the air passage opening / closing means 127, and operates in response to a control signal from the control device 56. One of the plurality of temperature sensors connected to the temperature detection circuit 63 faces the internal space of the storage chamber 21. Alternatively, the temperature sensor thereof is installed so as to be in close contact with the lower surface or the upper surface (outer surface) of the upper wall surface 21T. In any case, the temperature detection circuit 63 keeps the temperature at least during the period in which the heating means 8 is driven so that it can determine whether the internal atmospheric temperature of the storage chamber 21 or the ambient wall surface temperature exceeds a certain temperature. Get the detection data.

The drive circuit 128 for driving the air passage opening / closing means 127 operates preferentially when at least one of the left side heating coil 8L and the central heating coil 8M is driven by the control device 56. The reason for this is that, as is clear from the plan view of FIG. 36, only two of the left heating coil 8L and the central heating coil 8M are directly above the storage chamber 21, and the other right heating coil 8R is directly above. Because it is not in the position. In particular, the maximum thermal power of the left heating coil 8L is also 3000 W, which is also the reason why the heating capacity is larger than that of the other two heating coils. In other words, when at least one of the left side heating coil 8L and the central heating coil 8M operates by induction heating, there is a concern that the leakage magnetic flux from the heating coils 8L and 8M heats the wall surface of the storage chamber 21. be.

However, the drive circuit 128 that drives the air passage opening / closing means 127 is detected by the temperature detection circuit 63 even when either or both of the two heating coils 8M and 8L are driven by the control device 56. When the internal temperature of the storage chamber 21 becomes higher than a predetermined value, it is driven to open the air passage opening / closing means 127.

With the above configuration, for example, when the first cooking utensil 9 is placed on the left side heating coil 8L, the heating power, heating time, etc. are used by using the three input keys 17 on the left operation unit 12L. Is input, and a command to start heating is input with one of the input keys 17, the inverter circuit 55L is driven by the control device 56, and induction heating cooking is executed.

At the start of this cooking, the control device 56 does not transmit a predetermined drive command to the drive circuit 128 that drives the air passage opening / closing means 127. Therefore, the internal air passage of the branch duct 84 remains closed on the way, and the cooling air is not supplied from the cooling unit 57.

If the temperature of the storage chamber 21 exceeds a predetermined temperature while the cooking is in progress, the temperature detection circuit 63 detects the state, and the control device 56 receives the detection result in the drive circuit 128. In response, a command signal to open the air passage is transmitted. Then, the drive circuit 128 gives a drive signal to the air passage opening / closing means 127, and the air passage opening / closing means 127 moves the valve or the shutter to a predetermined opening position.

Therefore, a part of the cooling air of the first blower BM1 is supplied from the cooling unit 57 to the storage chamber 21 via the branch duct 84, and the internal atmospheric temperature of the storage chamber 21 can be lowered. In synchronization with the opening command of the air passage opening / closing means 127, the control device 56 may issue a command to the first blower BM1 to increase the blowing ability. By doing so, the amount of the cooling air supplied to the heating means 8 side is not reduced, and the heating means 8 and the inverter circuit board 55 can be stably cooled.

The first blower BM1 continues to blow air for, for example, about 10 minutes not only during cooking but also after cooking is completed, and the temperature of the heating means 8 or the top plate 4 which has become high during cooking. However, similarly, if the temperature of the storage chamber 21 still exceeds a predetermined temperature even after cooking is completed, the temperature detection circuit 63 detects the state and outputs this detection result. In response, the control device 56 continues the command to open the air passage to the drive circuit 128. Therefore, even if the heating means 8 or the top plate 4 which has become hot during cooking first drops below the reference temperature, the operation of the first blower BM1 continues during the period when the temperature of the storage chamber 21 does not drop. In some cases.

Further, in the first blower BM1, even when the right side heating coil 8R is driven by the control device 56, if induction heating is performed on the left side heating coil 8L before that, the right side heating coil 8R is used. At the time when the induction heating is started, the internal temperature of the storage chamber 21 may already be higher than the predetermined value. In such a case, the control device 56 continues the command to open the air passage to the air passage opening / closing means 127 of the branch duct 84 from the time before the induction heating is started by the right side heating coil 8R. From the beginning, the air passage opening / closing means 127 is in an open state.

The control device 56 may indicate that the wind is being sent to the storage chamber 21 by the display screen 20 of the operation unit 12, or the voice synthesizer 64 may notify the same information. If the temperature of the storage chamber 21 still exceeds a predetermined temperature even after the cooking is finished, the control device 56 does not complete a series of control operations. When completed, the power supply circuit 62 is automatically shut off by itself.

Reference form 11.
38 to 41 show the cooking apparatus according to the reference embodiment 11 of the present invention. In this reference form 11, a side cover is used to make the gap formed between the cooking device 1 and the kitchen furniture 2 inconspicuous. FIG. 38 is an enlarged vertical sectional view showing the front upper part of the cooking device and the front upper part of the kitchen furniture according to the first example of the reference form 11. FIG. 39 is an enlarged vertical sectional view showing a modified example of FIG. 35. FIG. 40 is an enlarged cross-sectional view showing the right end portion of the right cover of the cooking device according to the reference embodiment 11 and the left end portion of the furniture surface material adjacent thereto. FIG. 41 is an enlarged cross-sectional view showing a modified example of the embodiment of FIG. 40. The structure of the reference embodiment 11 is basically applicable to any of the above-described first embodiment and reference embodiments 1 to 10. The same or corresponding parts as those in FIGS. 1 to 15 may be designated by the same reference numerals, and duplicate description may be omitted.

The "side cover" as used in this embodiment means that when the kitchen furniture 2 is provided with this type of cooker 1, the gap (gap) generated between the kitchen furniture 2 and the cooker 1 is inconspicuous. It is an auxiliary part to make it work. The auxiliary parts used above the cooking device 1 and on the sides (either the right side, the left side, or one of them) are collectively referred to as "side covers".

Since various side covers have been proposed so far, they will be explained first.
In Japanese Patent Publication No. 5-52611, a side cover that closes the gap between the installation space of the cooker and the outer surface of the cooker is inserted into the gap from the front and is engaged with the outer surface of the cooker. The composition to match is introduced. As a result, it is not necessary to separately provide parts for attaching the side cover, and it is expected that the number of parts can be reduced and the cost can be reduced.

In Japanese Patent Application Laid-Open No. 10-110957, an insertion guide is formed on the side surface of the main body case of the cooking cooker (gas stove) in order to eliminate vertical deviation when assembling the side cover and deformation of the side cover when attaching and detaching. We are proposing a configuration in which the side cover is detachably attached to the main body case of the cooking cooker.

Further, in Japanese Patent Application Laid-Open No. 2012-47411, even when the door of the heating chamber is opened and closed, the installation work is easy without spoiling the appearance, the manufacturing cost can be reduced, and the side cover and the cooking with the side cover are provided. A vessel and its mounting method have been proposed. In this prior art, the side cover attached to the front left side of the main body case is composed of a first part and a second part in order to hide the gap between the main body case of the cooking cooker and the kitchen furniture. The part 1 is attached to the main body case in advance, and when the main body case of the cooking cooker is stored in the kitchen furniture, the second part is attached by using the first part. As a result, the installation work is easy and no special tools or parts are required, so that the manufacturing cost can be reduced.

Although various side covers as described above are not described in the above-described first embodiment and reference embodiments 1 to 10, the effect of the present invention can be obtained even if auxiliary parts for dealing with gaps such as the side covers are used. Has no effect. Further, the present invention is not premised on not using such a side cover, and may be used as needed. For example, when the side covers are finally located adjacent to each other on the right side of the cover 30 that covers the insertion slot 22 of the storage chamber 21, the position of the front surface of the side cover does not protrude forward from the front surface of the cover 30. The size and installation position of the side cover should be adjusted in this way. Ignoring the existence of such a side cover and focusing on aligning the front surface of the kitchen furniture 2 with the front surface of the cover 30, the configuration of the cooker 1 in the first embodiment and the reference embodiments 1 to 10 is made. Explained the positional relationship and composition of kitchen furniture 2. Therefore, even if the description "furniture surface material 41 of the kitchen furniture 2 adjacent to the cover 30" is described in the first embodiment and the reference embodiments 1 to 10, the above is described between the cover 30 and the furniture surface material 41. Side covers may be present.

In this reference form 10, it is an example using such a side cover.
In FIG. 38, as described in Reference Form 1, the GPT moves the cover 30 between the top surface of the handle portion 31A at the top of the cover 30 and the lower surface of the opening 2B at the front surface of the kitchen furniture 2. It is an upper void of about 20 mm to several millimeters (mm) formed to allow the above.

Reference numeral 121 denotes a support protrusion provided on the upper front surface of the main body case 3 corresponding to the upper gap GPT. This may be formed by cutting a part of the main body case 3 made of thin metal plate into a claw shape, but in the example of FIG. 38, a sharp rod-shaped one is separately formed and this is the front surface of the main body case 3. It is fixed to.

Reference numeral 122 denotes an upper side cover, which is entirely formed by integrally molding plastic, or is formed by extruding a metal material such as aluminum into a sash shape.
When the design of the front surface 30F of the cover 30 and the front surface 2F of the kitchen furniture 2 are unified, the surface of the side cover 122 is also matched to those designs, and the sense of unity of the design is improved. ..

Reference numeral 123 denotes a fitting hole formed in a hollow shape from the back surface side of the side cover to the inside thereof. When the fitting hole fits into the support protrusion 121, the side cover 122 is attached to the main body case 3. The side cover 122 is removed at the time of shipment of the cooking device 1 and is inserted into the packing box containing the main body case 3. Therefore, after the installer or the like installs the main body case 3 in the kitchen furniture 2, it is inserted from the outside of the opening 2B of the kitchen furniture 2 (to the left in FIG. 38) toward the tip of the support protrusion 121. ..

The cover 30 is attached to the main body case 3 from the outside of the opening 2B of the kitchen furniture 2 (to the left in FIG. 38) after the side cover 122 is attached to the main body case 3.

The length of the side cover 122 is set so as not to protrude from the front surface of the cover 30 attached later when the side cover 122 is attached to the main body case 3 as shown in FIG. 38.
With the above configuration, when the installation work of the cooking cooker 1 on the kitchen furniture 2 is completely completed, the front surface of the cover 30, the front surface of the handle portion 31A, and the side cover are placed on the assumed vertical surface VL. The front surface of 122 is all located. The front surface 2F at the top of the kitchen furniture 2 may also match the vertical surface VL.

Since the size of the upper gap GPT is not always constant when installed in various kitchen furniture 2, a plurality of side covers 122 having different thicknesses are assumed in such a situation. It may be prepared as an auxiliary part, or it may be prepared as an optional item and supplied in response to an order from the user of the cooking cooker 1, the installer, or the like. Alternatively, during the installation work, the fixing position of the side cover 122 with respect to the main body case 3 may be finely adjusted in the front-rear direction.

As is clear from the above description, in the reference embodiment of FIG. 38, when the cooking cooker 1 is incorporated in the kitchen furniture 2, the cover 30 covering the front surface of the cooking cooker 1 is at least on the left side or the right side thereof. There is no large step with the front surface of the kitchen furniture 2 adjacent to one side. Further, the position in the front-rear direction of the upper side cover 122 for making the gap between the upper part of the cover 30 and the front surface of the kitchen furniture 2 inconspicuous is also aligned with the position of the front surface 30F of the cover 30 of the cooking cooker 1. Can be done. As a result, it is possible to give a unified flat feeling to the entire front surface 2F of the kitchen furniture 2.

Next, FIG. 39 will be described. FIG. 39 is an enlarged vertical sectional view showing a modified example of the embodiment of FIG. 38.
In this modification, the length of the side cover 122 is up to a position retracted from the assumed vertical surface VL when the cooking cooker 1 is installed in the kitchen furniture 2. However, even in the configuration of FIG. 39, when the cover 30 is moved forward and the insertion port 22 of the storage chamber 21 is opened, the side cover 122 is located at a front position substantially close to the mouth edge of the insertion port 22. Therefore, the presence of the upper void GPT is diminished. Therefore, even in the configuration of FIG. 39, it is possible to avoid that the design of the front surface of the kitchen furniture 2 is significantly impaired by the upper gap GPT.

Next, FIG. 40 will be described. FIG. 40 is an enlarged cross-sectional view showing the right cover (decorative plate) 44 and the left end portion of the furniture surface material 41 adjacent to the right side of the right cover (decorative plate) 44 in the reference form 11. In FIG. 40, the GPR is the reference form 1. As described above, there is a right gap of about 20 mm to several millimeters (mm) between the decorative plate 44 and the left side surface of the kitchen furniture 2 adjacent to the right side of the cooking device 1. If the kitchen furniture 2 is also on the right side of the cooking cooker 1, there is a gap formed between the cover 30 and the right side surface of the kitchen furniture 2, and in that case, it is called a "left side gap" GPL.

Reference numeral 124 denotes a support protrusion provided on the front portion of the right side surface of the main body case 3 corresponding to the right side gap GPR. This is formed by cutting up a part of the main body case 3 made of thin metal and forming it into a claw shape. It should be noted that a sharp rod-shaped object may be separately formed and fixed to the front surface or the front side surface of the main body case 3.

Reference numeral 125 denotes a side cover on the right side, which is entirely formed by integrally molding plastic, or is formed by extruding a metal material such as aluminum into a sash shape.
When the design of the front surface 44F of the decorative plate 44 and the front surface 2F of the kitchen furniture 2 are unified, the surface of the side cover 125 is also matched to those designs, and the sense of unity of the design is improved. do.

Reference numeral 126 denotes a fitting hole formed in a hollow shape from the back surface side of the side cover to the inside thereof. When the fitting hole fits into the support protrusion 124, the side cover 125 is in a state of being attached to the main body case 3. The side cover 125 was removed at the time of shipment of the cooking device 1 and inserted into the packing box containing the main body case 3. Therefore, after the installer or the like installs the main body case 3 in the kitchen furniture 2, the kitchen furniture 2 is directed from the outside of the opening 2B (downward of the paper surface in FIG. 40) toward the tip of the support protrusion 123. insert.

The decorative plate 44 is attached to the main body case 3 from the outside of the opening 2B of the kitchen furniture 2 (downward on the paper surface in FIG. 40) after the side cover 125 is attached to the main body case 3.

The length of the side cover 125 is set so as not to protrude from the front surface 44F of the decorative plate 44 attached later when the side cover 125 is attached to the main body case 3 as shown in FIG. 40.
With the above configuration, when the installation work of the cooking device 1 on the kitchen furniture 2 is completely completed, the front surface 44F of the decorative plate 44 and the front surface 125F of the side cover 125 are placed on the assumed vertical surface HL. However, all will be located. The furniture surface material 41 of the kitchen furniture 2 immediately to the right of the side cover 125 also matches the vertical surface VL. The vertical plane VL of FIG. 38 and the vertical plane HL of FIG. 40 are at the same position.

Since the size of the right side gap GPR is not always constant when installed in various kitchen furniture 2, the thickness (horizontal width dimension) of the side cover 125 is made different in consideration of such a situation. A plurality of items may be prepared as auxiliary parts, or may be prepared as optional items and supplied in response to an order from the user of the cooking cooker 1, the installer, or the like.

Further, a plurality of side covers 125 having different lengths may be prepared as auxiliary parts. Alternatively, the fixing position of the main body case 3 may be finely adjusted in the front-rear direction during the installation work.

Next, a modification of FIG. 41 will be described. FIG. 41 is an enlarged cross-sectional view showing a modified example of FIG. 40.
In this modification, the length of the side cover 122 is up to a position retracted from the assumed vertical plane HL at the stage when the cooking cooker 1 is installed in the kitchen furniture 2. However, even in the configuration of FIG. 41, when the cover 30 is moved forward and the insertion port 22 of the storage chamber 21 is opened, the side cover 125 is located at a front position substantially close to the mouth edge of the insertion port 22. Therefore, the presence of the right-side gap GPR diminishes. Therefore, even in the configuration of FIG. 41, it can be avoided that the design of the front surface of the kitchen furniture 2 is significantly impaired due to the presence of the right side gap GPR.

Other reference forms.
Although various side covers 122 and 125 as described above are not described in the first embodiment and the reference embodiments 1 to 10 of the present invention, even if auxiliary parts for gaps such as the side covers are used, the side covers 122 and 125 may be used. There is no effect on the effect of the present invention. Further, the present invention is not premised on not using such side covers 122 and 125, and may be used as needed. For example, when the side covers 125 are finally located adjacent to each other on the right side of the cover 30 that covers the insertion slot 22 of the storage chamber 21, the position of the front surface of the side cover 125 is forward of the front surface of the cover 30. The size and installation position of the side cover should be adjusted so that it does not protrude.

In the reference embodiment 1 and the like of the present invention, as described with reference to FIG. 10, an intake port (not shown) and an exhaust port 6 (see FIGS. 4 and 10) are formed on the rear frame plate 5, respectively. Then, the upper part of the intake port is covered with the intake cover 7A, but in addition to the intake from the upper surface of the main body case 3 as described above, the intake may be made from the side surface of the main body case 3. .. Alternatively, the intake from the upper surface of the main body case 3 may be completely stopped, and the intake from the side surface of the main body case 3 may be used. Specifically, an intake port (not shown) may be formed on either one or both of the rear surface plate 3H of the main body case and the inclined surface portion 3J. In the reference embodiment 4, the first blower BM1 sucks the air outside the main body case 3 from a large number of suction holes (not shown) provided on the wall surface (rear surface plate 3H) on the back side of the main body case 3. It is a composition.

In the reference embodiment 1 of the present invention, the intake cover 7A and the exhaust cover 7B are detachably provided on the upper surface of the main body case 3. For example, the structure is such that the exhaust cover 7B is placed above the exhaust port 6. However, it is not necessary to prepare the intake cover 7A and the exhaust cover 7B separately in this way, and they may be covered with an integrated one. Further, even when the exhaust port and the intake port are provided on the upper surface of the main body case 3, the exhaust cover and the exhaust cover are provided so that the user cannot see the exhaust port and the intake port when viewed from the operation unit 12 side of the main body case 3. A hole for intake or intake may be provided on the back surface of the intake cover. In this way, exhaust and intake are performed from the exhaust cover and the intake cover in the direction diagonally upward on the rear side.

In the first embodiment and the reference embodiments 1 to 11, it has been explained that the cover 30 and the decorative plate 44 are attached to the main body case 3, but this is when the cooker 1 is shipped to the main body case 3. It does not mean that it is always installed. To facilitate the installation work on the kitchen furniture 2 as shown in FIG. 15, and to prevent decorative parts such as covers from hitting the kitchen furniture 2 and being damaged or scratched during the installation work. Therefore, for example, a cushioning material called a "protective sheet" or a "protective panel" and a protective member that can be discarded are attached to the front surface of the main body case 3 and shipped. Then, after the worker of the store or the installation company of the cooking cooker 1 horizontally inserts the cooking cooker 1 into the kitchen furniture 2 as shown in FIG. 15, the above-mentioned "protective sheet" is used. It is good to remove the "protective panel" and then attach the cover 30 or the decorative plate 44. Therefore, also in the first embodiment and the reference embodiments 1 to 11 of the present invention, the cover 30 and the decorative plate 44 as described above, and further as described in the reference embodiment 11. The various side covers 122 and 125 may be shipped together in a packing box containing the main body case 3 of the cooking cooker 1.

In the first embodiment and the reference embodiments 1 to 11, the storage chamber 21 is located on the left side from the center of the main body case 3, but it may be turned upside down and provided on the right side. Further, if the internal space of the storage chamber 21 is divided into two or more, and all the front insertion ports thereof are opened and closed by one cover 30, all the front side insertion openings can be opened by opening one cover 30. The inside of the storage chamber 21 can be opened forward, which makes it easier to store and take out the cooking utensil 9, other seasonings, foodstuffs, miscellaneous goods, and the like.

Further, when the inside of the storage chamber 21 is divided into a plurality of parts, the storage chamber 21 may be divided into two or more by a partition plate, a breathable net or a frame. That is, since it is sufficient that the storage chamber 21 can store, for example, the first cooking utensil 9, the surplus space may be used for storing other cooking utensils, small cooking utensils, and the like. As introduced in FIG. 26 of Reference Form 7, if fresh air outside the main body case 3 is positively introduced into the storage chamber 21, the storage chamber 21 is unlikely to become a closed space for a long period of time, and thus mold is formed. Occurrence can also be suppressed. Further, as described with reference to FIG. 26, if the air sterilizing means 102 is provided, it is possible to more reliably prevent the generation of mold and the generation of malodor due to the mold.

In the first embodiment and the reference embodiments 1 to 11, the first cooking utensil 9 is a dish portion 9A made of magnetic metal such as stainless steel or iron, and a heat-resistant glass lid 9B that covers the upper part of the dish portion. It was composed of, but this configuration may be changed. For example, a glass lid 9B and a metal lid such as a casting may be prepared in one dish portion 9A and used by the user according to the type of cooking. The metal lid is used when the lid is easily lifted due to the pressure increase associated with cooking such as cooking rice. In other words, since the lid itself is heavy, it will not open accidentally during rice cooking.

Further, the dish portion 9A may be provided with a latch that rotates with the dish portion as a fulcrum so that the lid body 9B can be locked, and the lid body 9B may be fixed so as not to open during cooking.
Further, the cooking utensil 9 may not necessarily have the lid 9B. Further, when the cooking utensil 9 is stored in the storage chamber 21, the lid 9B may not be placed on the dish portion 9A (in the same direction as during cooking) and cannot be stored. For example, the lid 9B may be turned upside down (turned over) and stored in that state. In this way, the overall height of the cooking utensil 9 becomes lower, and it may be possible to accommodate even a narrow storage chamber 21, but this depends on the size and shape of the lid 9B and the dish portion 9A.

A black ceramic coating may be applied to the entire surface of the metal dish portion 9A of the first cooking utensil 9. Since the far-infrared effect can be expected from such a ceramic coating, rice cooking and other cooking can be further heated to the inside, and delicious dishes can be prepared.

The embodiments and reference embodiments disclosed this time should be considered to be exemplary and not restrictive in all respects. Substantial scope of the present invention is shown by the scope of claims, not the above description, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.

The induction heating cooker according to the present invention can be widely used not only in the kitchen of a general house but also in a kitchen such as a public facility or a store.
