  In FIG. 5, reference numeral 45 denotes a sealing member mounted on the front surface of the main body case 3 directly above the insertion opening 22. This seal material is formed of a highly elastic material such as silicon rubber, for example, and when the insertion port 22 is closed by the cover 30, the tip is in contact with the back surface of the handle portion 31A.

  In FIG. 5, 30F indicates the front surface of the cover 30. When the heating cooker 1 is incorporated into the kitchen furniture 2, the front surface is a furniture such as a door or drawer located below and adjacent to the lower side. It becomes 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 aligned with the front surface 40F of the furniture facing 40 when viewed from directly above. The furniture surface material 40 and the cover 30 can present the user with a design feeling such that the kitchen furniture 2 has a unified plane even when viewed from the front or 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. 5, 2F indicates the front (front) of the kitchen furniture 2. When the heating cooker 1 is incorporated into the kitchen furniture 2, the front surface of the cover 30 is at a position coincident with the front surface 2F of the kitchen furniture 2 or at a position slightly behind (for example, several mm) 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 the furniture surface material 40. When the heating cooker 1 is incorporated into the kitchen furniture 2, the furniture facing 41 is a structure such as a door or a drawer that is present adjacent to the right side. The position of the front surface 44F of the right cover 44 is also aligned with the position of the surface 41F of the furniture surface material 41. As a result, the surface of the cover 30 and the surfaces 40F and 41F of the furniture facings 40 and 41 are all aligned in the same vertical plane.

  In FIG. 5, the cover 43 is a wall which divides the interior of the kitchen furniture 2 up and down into a plurality of rooms, and the lower side of this wall is often used for storing 49 of kitchenware, food, etc., for example.

  According to the configuration described above, when the heating cooker 1 is incorporated into the kitchen furniture 2, the entire front face of the kitchen furniture 2 presents substantially one plane. When the user looks at the kitchen furniture 2, the entire front (front) is designed so that it can be recognized as a clean and unifying design. The kitchen furniture 2 and the heating cooker 1 are not intended by the present invention to be designed by the same manufacturer, and in fact, the kitchen furniture is manufactured and sold by kitchen furniture such as sinks and by home equipment vendors. The heating cooker 1 is manufactured and sold by a home appliance maker. The two types of furniture surface materials 40 and 41 may be the same. Moreover, these furniture facings do not have to be moved back and forth, such as doors and drawers. For example, it may always be fixed on the surface of the kitchen furniture 2 and not move at all.

  In FIG. 3 and FIG. 5, the color and surface shape (presence or absence of pattern, gloss, unevenness, etc.) of the front surface 30F, 44F of the cover 30 and the right cover 44 are the same as those of the front surface of the furniture surface material 40, 41. When combined with the color and surface form, the uniform design feeling is further enhanced. For example, when the entire front surface of the furniture facings 40 and 41 is uniform in 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 uniform in color or wood grain design of the same color. For example, only the front faces 30F and 44F do not stand out in the kitchen furniture 2. In addition, the color and pattern of the front of the cover 30 and the furniture surface materials 40 and 41 may be made different to show the presence of the cover 30 which covers the insertion opening 22 of the storage room 21. In addition, 42 is a frame line displayed by printing on the front of the furniture facings 40 and 41, and it does not form physical unevenness on the front of the furniture facings 40 and 41, but it is made of glossy metal. You may stick a thin board etc., and you may be what gave a sense of quality.

  In the kitchen furniture 2 shown in FIG. 2, since the heating cooker 1 is incorporated at the leftmost side, the furniture surface material 41 is formed adjacent to the right side of the right cover 44. When the heating cooker 1 is incorporated, the furniture surface material 41 is adjacent to the left side of the cover 30, and the furniture surface material 41 is also adjacent to the right side of the right cover 30. Even in such a case, as described above, only the portion of the heating cooker 1 does not protrude forward, and the entire front face of the kitchen furniture 2 can be made to exhibit approximately one plane.

  As shown in FIG. 6, when the cover 30 is pulled forward, the saucer 26 can be pulled forward from the storage room 21. However, it is preferable to limit the amount of withdrawal to a certain limit. Since the first cooking appliance 9 described above is placed in the tray 26, it has a mechanism for preventing the tray 26 from being pulled out more than necessary and for preventing the tray 26 from falling. Not. However, this can be easily realized by providing a protrusion at the rear of the storage compartment 21 and by providing a stopper on the inside of the storage compartment 21 so as to touch when the receptacle 26 is pulled out to a certain limit position.

  In FIG. 6, LD indicates the maximum withdrawal amount when the cover 30 is pulled forward. The maximum withdrawal amount is set such that the first cooker 9 can be lifted out of the top of the tray 26 and carried out of the insertion opening 22 of the storage room 21. Further, as shown in FIG. 6, even when the tray 26 is pulled forward to a certain limit, the tray 26 is configured to be supported substantially horizontally. This is because the rigid members such as support pins projecting from the left and right inner wall surfaces of the storage chamber 21 are engaged with the grooves provided on the left and right sides of the receiving tray 26. As shown in FIG. 6, the weight of the first cooking appliance 9 and the weight of the cover 30 are supported by the plate 26, and the total weight of the plate 26 is supported by the left and right wall surfaces of the storage chamber 21. There is.

  In FIG. 5 and FIG. 6, 50 is a permanent magnet attached to the rear back side of the tray 26, and 51 is a magnetic sensing switch (reed switch) installed on the rear wall 23 of the storage room 21. Since the reed switch 51 detects the approach of the permanent magnet 50 in the operation start preparation stage of the heating cooker 1 when the tray 26 is inserted to the deepest predetermined position of the storage room 21, a signal indicating ON is sent Since the detection signal is output to the control unit 56, the control unit 56 determines that the cover 30 is closed and that the heating and cooking may 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 constituted by both the control device 56 and the reed switch 51.

  As shown in FIG. 6, the storage room 21 is surrounded by a series of wall materials 51 on the left and right sides and the upper and lower surfaces excluding the insertion port 22 and the rear side, and the cooling air of the blower BM described later infiltrates. It is divided as a closed space. For this reason, the cooling air of the blower BM does not flow into the space of the storage chamber 21 and flows in a predetermined air path, so that the cooling efficiency of the cooling space 52 described later is not reduced.

  The three induction heating coils 8R, 8L, and 8M described above, the inverter circuit board 55 described later, and the blower BM are disposed in the cooling space 52 outside the closed space inside the main body case 3 ing. Since the blower BM generates a fresh air flow inside the main body case 3 during induction heating and cooking, temperature rise of the induction heating coils 8R, 8L, 8M and the inverter circuit board 55 is prevented.

  The cooling space 52 communicates with the outside of the main body case 3 through an air inlet (not shown) formed in the rear frame plate 5. Further, the cooling space 52 communicates with the outside of the main body case 3 through the exhaust port 6 (see FIG. 5) formed in the rear frame plate 5.

  Returning to FIG. 1, the internal structure of the main body case 3 will be described. When the blower BM is operated, an intake flow indicated by an arrow 53 is generated in an intake port (not shown) formed in the rear frame plate 5. That is, the blower BM is installed at the right rear position of the main body case 3 at the upstream portion of the cooling space 52. The inverter circuit board 55 is disposed downstream of the cooling air sucked by the fan BM, and the cooling air flow from the fan BM is guided to two air paths downstream of the inverter circuit board 55. The controller 56 is disposed downstream of one air passage, and the three induction heating coils 8R, 8L, 8M are disposed downstream of the other air passage. The cooling air having passed through the two air passages is finally discharged to the outside of the main body case 3 through the exhaust port 6 (see FIG. 5) formed in the rear frame plate 5. Although a plurality of ducts and partition plates are installed to guide the cooling air, the illustration is omitted.

Next, the configuration of the control relationship of the heating cooker 1 will be described with reference to FIG.
A main power switch 61 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 which is opened and closed by the user, 62 is a power supply circuit to which electric energy is supplied through the main power switch 61, and 56 is a predetermined constant pressure current supplied from the power supply circuit Is a control device mainly composed of a microcomputer.

  The microcomputer is composed of four parts: an input part, an output part, a storage part, and a CPU (calculation control part), and the storage part stores in advance the energization control program corresponding to various cooking menus ( Stored). In addition to the storage unit (ROM, RAM) of the microcomputer, a large capacity storage device 56R for recording abnormality monitoring information is incorporated.

  During induction cooking, monitoring of the presence or absence of an electrical abnormality is performed by the controller 56. For this purpose, 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 heating cooker is abnormally high. For example, although the display screen 20 is constituted by a liquid crystal display substrate, it is relatively weak to heat, so it is monitored through the temperature detection circuit 63 so as not to exceed a predetermined temperature (for example 60.degree. C.). When it is exceeded, it is judged by the controller 56 as "abnormal preliminary state" (Note that the abnormal preliminary state is limited to the case where the detected temperature is in the range of 60 ° C to 65 ° C. The risk increases when it exceeds 65 ° C Controller 56 identifies a true abnormal condition).

  In this abnormal preparatory state, the heating operation is not immediately stopped, and the improvement is achieved by raising the air blowing capacity of the fan (cooling fan) BM that is cooling the internal space of the main body case 3. However, when the temperature exceeds 65 ° C., an abnormal state is judged by the control device 56, and the heating operation is immediately stopped. For example, power supply of the inverter circuit 55R (described later) supplying high frequency power to the right heating coil 8R. Shut off.

  And it shows the change condition of the electrical and physical (temperature of the display screen 20 mentioned above as an example) of the main part of the cooking device 1 at least in the period from such an abnormal preparatory state to emergency stop (abnormality monitoring) The information is stored in the storage unit 56R of the control device 56. The abnormality monitoring information stored in the storage unit 56R starts being acquired when the main power switch 61 is turned on, and reflects the history of electrical and physical changes until cooking is stopped. Therefore, information on the cooking menu (for example, "boiling", "simmered", "frying", etc.) selected after that and the thermal power of induction heating are also recorded in time series. If an emergency stop occurs due to an abnormal state on the way, the abnormality monitoring information is stored in the storage device 56R up to that point.

  Further, in the first embodiment, in order to monitor the operation of the induction heating cooker 2 over a wider range and acquire data, monitoring information of the period from the time the main power switch 61 is turned on to the emergency stop of induction heating cooking. The controller 56 can obtain the information.

In the inverter circuit board 55 described in FIG. 4, three inverter circuits 55L, 55M and 55R are built.
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 known resonance circuit to which a resonance capacitor or the like is connected.

  55R is an inverter circuit for supplying a high frequency current to the induction heating coil 8R on the right side. Reference numeral 55M denotes an inverter circuit for supplying a high frequency current to the central induction heating coil 8M.

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

  Reference numeral 64 denotes a voice synthesizer which synthesizes electronically generated voices, and provides guidance of the operation to the user, notification of occurrence of abnormality, and the like by voice from the speaker 65 each time.

  63 is the above-mentioned temperature detection circuit. This temperature detection circuit includes the temperature of the first cooking appliance 9 on the top plate 4 heated by the three induction heating coils 8L, 8M, 8R described above, the temperature of the top plate 4 and the cooling space 52. Temperature detection information is received from a plurality of temperature sensors (not shown) for detecting the ambient temperature, temperatures of the inverter circuits 55L, 55M, 55R, the display screen 20, etc., and the temperature detection results are sent to the control unit 56. send. 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 (internal 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 time It is supposed to be This may be, for example, a radio clock, and always informs the current date and the exact time in seconds when requested from the control device 56, and is set to the correct time in the manufacturing stage of the heating cooker 1 . Therefore, even if the main power supply of the heating cooker 1 is turned off and then turned on again, the time information of the clock circuit is not affected, and there is a function of always transmitting the latest correct time to the control device 56. For this reason, the abnormality monitoring information recorded in the storage device 56R of the control device 56 is also always recorded and saved with accurate time at the same time.

  Reference numeral 67 denotes a vibration-sensing device for detecting shaking at the occurrence of an earthquake, and when detecting a predetermined seismic intensity (acceleration) or more, sends a vibration sensing signal to the control unit 56, and the control unit 56 receives the signal and receives the earthquake. Judging that it occurs, the power supply of all the heating means in use is cut off instantaneously.

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

  The "adapter" refers to a control device provided between an individual home appliance such as the heating cooker 1 and its power source. For example, an adapter as used herein refers to an adapter as disclosed in Japanese Patent Application Laid-Open Nos. 2011-205821 and 2011-55623, has a power plug and an outlet, and is an electrical device that is to control energization to the outlet. (In this Embodiment 1, the heating cooker 1) is connected. When the adapter receives the power command signal by wireless communication, the power supply of the home appliance (heating cooker 1) to be controlled is restricted or cut off. In this way, an adapter is connected to the existing home appliance (heating cooker 1), and a power control signal (not shown) for limiting the total amount of electric power in the home is sent to the adapter, and Since the adapter controls the heating cooker 1, by interposing the adapter on the power supply side of the existing heating cooker 1 as well, there is obtained an advantage that power can be centrally controlled by the power command device.

  As shown in FIG. 4, the operation unit 12 has an input key 18. When this input key 18 is touch-operated, the control unit 56 is connected to the wide area communication network in the space outside the home via the wireless communication means 68, and from a server (not shown) installed by the information provider , To obtain information useful for using the first cookware 9. The acquired information is stored in the storage device 56R. Further, in addition to the display on the display screen 20 or in addition to this display, the voice synthesizer 64 gives a voice notification from the speaker 65.

  Reference numeral 69 denotes a drive circuit for driving the display screen 20. The drive circuit is connected to the control unit 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.

Since it is the above structure, next, cooking operation is demonstrated.
Next, the configuration of the control relationship of the heating cooker 1 will be described with reference to FIG.
First, when the user turns on the main power switch 61, electrical energy is supplied to the power circuit 62 through the main power switch. Then, a predetermined constant pressure current is supplied from the power supply circuit, and the control device 56 is started.
The control device 56 activates the temperature detection circuit 63, the voice synthesizer 64, and the display unit drive circuit 69, and when an abnormal temperature condition is not detected by the temperature detection circuit, and an abnormal voltage or current is not detected. Complete the self-checking operation at startup. Then, the display screen 20 displays that the heating and cooking can be started, and the voice synthesizer 64 also notifies via the speaker.

  Therefore, the cover 30 of the storage room 21 is pulled out to the front, and the first cooking appliance 9 is taken out and placed at a position just above the left heating coil 8L as shown in FIGS. 4 and 5, for example. Although the first cooking appliance 9 can be used for induction cooking only with the plate portion 9A, when the lid 9B is used at the same time, the food to be cooked (for example, fish, meat, etc.) does not scatter, and hot air Since it does not escape, the heating efficiency is improved.

  When the reed switch 51 which constitutes a part of the safety device SD is opened (OFF) after the control device 56 completes the self-checking operation at the time of start-up, the tray 26 is the innermost predetermined part of the storage room 21. It is determined that it is derived from the position. After that, it is detected whether or not an object to be heated such as a metal pan is placed on any of the three heating coils 8L, 8M, 8R (Such methods have already been proposed as such detection methods. (Detailed explanation is omitted).

When the control device 56 detects that the first cooking appliance 9 is present on the left side heating coil 8L or the right side heating coil 8R, the display screen 20 and the voice synthesis device 64 operate the heating and cooking condition by the operation unit 12. Prompt to input from
When the first cooker 9 is placed on the left heating coil 8L, the firepower, heating time, etc. are input using the three input keys 17 on the left operation unit 12L, and the input keys When a command to start heating is input in one of the seventeen, the inverter circuit 55L is driven by the controller 56, and induction heating and cooking are performed.

  Even before, during, or after such induction cooking, when the touch key 18 on the operation unit 12 is touch-operated, the control device 56 transmits the outside of the home via the wireless communication means 68. It is connected to a wide area communication network in the space, and information useful for using the first cooking appliance 9 is acquired in real time from a server (not shown) installed by an information provider, and the acquired information is stored in the memory The user uses the first cooking appliance 9 as it is displayed on the display screen 20 while being stored in the device 56R, or is notified by voice from the speaker 65 by the voice synthesizer 64 in addition to this display. If you do, you can use external useful information and it is convenient. For example, when burning fish, it is possible to know the heating power of the heating coil 8L.

  While such induction cooking is being performed, the user can stop the heating operation at an arbitrary timing, but the stop command can be performed by one of the input keys 17. In the event of an emergency, pressing the operation key 14 of the main power switch 64 can easily make the automatic stop.

  The first cooking appliance 9 that has finished induction cooking first pulls out the cover 30 of the storage room 21 to the front, pulls the saucer 26 forward from the storage room 21, and then the first cookware 9 is placed on the saucer 26. The cookware 9 of should be put. Even if the first cooking appliance 9 is still immediately after the cooking and the temperature is high, the tray 26 is formed of metal or heat-resistant plastic, so there is no problem at all.

  The control device 56 detects that the tray 26 has been returned to the deepest predetermined position of the storage room 21 when the reed switch 51 which constitutes 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. Then, since the storage room 21 returns to the closed space where there is no air communication with the outside, as described above, the internal atmosphere of the storage room 21 is still under the influence of the high temperature first cooking appliance 9. It is assumed that the temperature rises. However, in the first embodiment, the storage room 21 is designed in consideration of such a temperature rise, and the outer surface temperature of the main body case 3 and the surface temperature of the cover 30 are never raised to a predetermined temperature or more.

  As one of the measures to suppress the temperature rise of the internal atmosphere of the storage room 21, a vent may be provided on the back surface, ceiling surface, etc. of the storage room 21 to make the storage room 21 communicate with the cooling space 52. In that case, if the air is further positively cooled by air, a part of the cooling air of the blower BM is introduced into the inside of the storage room 21 and discharged therefrom, and finally the hot air of the storage room 21 is Like the exhaust flow from the exhaust port 6 (see FIG. 5), it may be discharged from the main body case 3 to the outside.

  In the above description, induction cooking was performed using the first cooking appliance 9, but other common cooking appliances such as metal pots and pans, that is, the second and third cooking appliances described above Cooking is possible with 10 and 11.

  Next, the operation of the control device 56 in the case of operating the touch-type input key 19 for confirmation instruction for requesting the control device 56 for the presence result of the first cooking appliance 9 will be described. When the input key 19 is operated, the control device 56 detects whether or not the first cooking appliance 9 is inside the storage room 21. For that purpose, a sensor for discriminating the case where the first cooking appliance 9 is present and the case where the first cooking appliance 9 is absent, for example, that the first cooking appliance 9 is present at a predetermined position on the tray 26 is magnetically Alternatively, a sensor that detects light or weight is provided separately. When it is detected by the reed switch 51 that the cover 30 is opened and then closed, changes in the magnetic, optical or weight (the weight including the pan 26) may be changed before and after the opening. It is judged that the presence of the first cooking appliance 9 which is made of metal and relatively heavy (for example, 500 g or more) is detected. If the first cooking appliance 9 is present, the user is notified that the presence or absence of the cooking appliance 9 is displayed on the display screen 20 or notified by the voice synthesizer 64 immediately after the input key 19 is operated. For example, even when another cooking is performed on the heating coil 8L on the right side, the storage state of the first cooking appliance 9 can be confirmed immediately without pulling the cover 30 forward, which is convenient. is there.

Embodiment 2
10 to 11 show the heating cooker according to the second embodiment. The feature of this embodiment is that the main body of the heating cooker 1 is divided into an upper unit and a lower unit. In addition, the same code | symbol may be attached | subjected to an equivalent or equivalent part to FIGS. 1-9, and the overlapping description may be abbreviate | omitted.

  As shown in FIG. 10, the main body case 3 of the heating cooker 1 according to the second embodiment includes an upper unit TU incorporating a heating unit comprising a left heating coil 8L, a right heating coil 8R and a central heating coil 8M, and a storage unit A feature is that lower units KU incorporating the chamber 21 are separately formed.

  The main body case 3 constituting the outer shell of the upper unit TU is configured of a body 3U and a single bottom plate 3B coupled to the body with a screw or the like so as to cover the entire bottom surface of the body. 3C is a screw hole through which a screw for coupling the bottom plate 3B to the main body case 3 is inserted. The body 3U and the bottom plate 3B are both made of thin metal plates. Since the outside diameter size of the body 3U is smaller than the diameter of the installation port 2A of the kitchen furniture 2, it can be inserted into the installation port 2A as shown in the first embodiment (see FIG. 9).

  On the other hand, the lower unit KU, which constitutes the outer shell thereof, is a box-shaped lower main body case 70. Since the lower main body case 70 does not accommodate the heating portion including the left side heating coil 8L, the right side heating coil 8R and the central heating coil 8M, the whole may be formed of a plastic material. That is, the lower main body case 70 does not store important electric parts such as the left side heating coil 8L, the inverter circuit board 55, and the heat generating parts, and supports the top plate 4 which is required to have strength. Since it is not a structure, it is not necessary to form a box structure of sheet metal to completely surround front and rear and left and right as in the first embodiment, and the structure of the lower main body case 70 can be simplified to significantly reduce the manufacturing cost.

In addition, the upper unit TU is placed on the lower unit KU, the two are detachably connected with each other by a fixing bracket etc. first, and such a connected object is then inserted from the installation port 2A. You may install in a predetermined position.

  According to the second embodiment shown in FIG. 10, since the upper unit TU incorporating the heating unit and the lower unit KU incorporating the storage chamber 21 can be formed separately, as shown in the first embodiment. Since it is not necessary to form a large main body case by press processing or the like and the main body case 3 itself is miniaturized, weight can be reduced and cost reduction can be expected. Further, since the outer shell case of the lower unit KU can be formed alone, a plastic material relatively lighter than the metal material constituting the main body case 3 can be used. As a whole, a significant reduction in manufacturing cost and weight can be expected.

FIG. 11 shows a modification of the second embodiment shown in FIG.

However, main components such as the blower BM and the inverter circuit board are fixed to a support formed in the inside of the main body case 3 constituting the outer shell of the upper unit TU.
On the other hand, the lower unit KU, which constitutes the outer shell thereof, is a box-shaped lower main body case 70. Then, on the ceiling surface of the lower main body case 70, flanges 70R, 70B, 70L for fixing to the main body case 3 of the upper unit TU with a screw or the like are formed. In each flange, a screw hole 71 for inserting a screw is formed in advance. Since the lower main body case 70 does not accommodate the heating portion including the left side heating coil 8L, the right side heating coil 8R and the central heating coil 8M, the whole may be formed of a plastic material.

  In the case of incorporating in the kitchen furniture 2, first, the upper unit TU is placed on the lower unit KU, and the both are coupled with screws using the screw holes 71 of the flange. Thus, the whole may be made into one unit, and then it may be inserted from the installation port 2A and fixed at a predetermined position.

  According to the second embodiment shown in FIG. 11, the upper unit TU incorporating the heating unit and the lower unit KU incorporating the storage chamber 21 can be formed separately, as shown in the first embodiment. Since it is not necessary to form a large main body case by press processing or the like and the main body case 3 itself is miniaturized, weight can be reduced and cost reduction can be expected. Further, since the outer shell case of the lower unit KU can be formed alone, a plastic material relatively lighter than the metal material constituting the main body case 3 can be used. As a whole, a significant reduction in manufacturing cost and weight can be expected.

As a modification of the second embodiment shown in FIGS. 10 and 11, the decorative frame 44 is eliminated, the cover 30 is extended in the right direction to the portion where the decorative frame 44 is present, and the entire front surface of the lower main body case 70 is May be covered with the cover 30.

In FIG. 15 and FIG. 16, 8M is a central heating coil, and the maximum outside dimension DM1 is about 100 to 120 mm.
8R is a central heating coil, and the maximum outside dimension DM3 is about 200 mm.

8L is a left side heating coil. MC is a main heating coil at the center of the left induction heating coil 8L, and is disposed close to the top plate 4 on which the object to be heated is placed. In FIG. 15 and FIG. 16, what is indicated by a broken circle is the range of the bottom portion of the object to be heated such as a metal pan.
Further, the main heating coil is finally formed by winding a coil wire in a disk shape so that the outer shape becomes circular with a central point X1 as a base point. The diameter (maximum outer diameter dimension) DA2 of the main heating coil MC is about 180 mm. In the fifth embodiment, for example, a capability of 2000 W of rated maximum power consumption (maximum thermal power) is provided. The main heating coil consists of two parts, an annular inner coil and an annular outer coil connected in series thereto.

SC1 to SC4 are four oblong auxiliary heating coils, and are symmetrically arranged at front and rear, right and left at equal intervals with the central 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, which will be described by an example of “5 mm” in the following description) 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. 15, these four sub-heating coils SC1 to SC4 have a tangential direction that is exactly the center line of the respective sub-heating coils SC1 to SC4 in the tangential direction around the main heating coil MC of radius R1 from the center point X1. It matches with. In other words, it coincides with the major axis direction.
The sub heating coils SC <b> 1 to SC <b> 4 extend while curving their respective collective lines into an oval shape, and constitute one electrically closed circuit. Further, the vertical dimension (also referred to as height dimension and thickness) of the main heating coil MC and the vertical dimension of each of the sub heating coils SC1 to SC4 are the same, and the opposing distance between their upper surface and the lower surface of the top plate is It is installed and fixed horizontally so as to have the same dimensions.

Specifically, inverter circuits 55R1 and 55R2 dedicated to each of the two heating coils are provided. In FIG. 15, two inverter circuits 55R1 and 55R2 are collectively shown by reference numeral 55R.

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 profile of the inner annular coil is about 100 mm.
Therefore, for example, only the inner annular coil can be driven to inductively heat the small-diameter (for example, about 80 mm to 120 mm) object N, while the outer annular coil and the inner annular coil can be simultaneously driven (or It is also possible to heat one having a larger diameter, for example about 220 mm, by alternately energizing for a short time.

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

  Generally, the impedance of the induction heating coil changes depending on the presence or absence and the 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 fifth embodiment, a current detection unit (detection means) 80A for detecting the amount of current flowing through the main heating coil 55MC and the sub heating coils SC1 to SC4 is provided. The current detection unit is a type of the object placement determination unit 80 described later.

It provides a control signal. That is, control device 56 receives a signal (data indicating the placement state of the object to be heated) relating to the amount of current flowing to main heating coil MC and sub heating coils SC1 to SC4 detected by current detection unit 80A. Is not placed or if it is determined that the diameter of the object to be heated is smaller than a 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 to stop (if the supply has already been started).

  According to the fifth embodiment, the control device 56 supplies the main inverter circuit 56LM and the sub inverter circuits 55LS1 to 55LS4 with control signals according to the placement state of the object to be heated, thereby the main heating coil MC and the sub heating circuit MC. Power feeding to heating coils SC1 to SC4 can be controlled independently of each other. In addition, the main heating coil MC at the center is not driven (turned off), and all the sub-heating coils SC1 to SC4 are driven (turned on) to make the pan surface of the pan (side of the pan) A cooking method such as preheating only can be realized.

  In FIG. 15, reference numeral 82 denotes a temperature sensor in which a temperature detection element is provided in a space secured between the outer annular coil forming the main heating coil MC and the inner annular coil. For example, it is a temperature sensor which detects infrared rays and senses temperature. This temperature sensor also constitutes a part of the heating object placement judgment unit 80. That is, when the object to be heated such as the first cooking appliance 9 is placed on the left heating coil 8L and induction heating is started, this temperature sensor is present when the temperature to be heated exceeds a certain temperature. Is detected.

The thickness and the position in the front-rear direction of the cover 30 are controlled so that the front surface 87F of the furniture surface material 87 and the cover 30 are aligned in a horizontal line when viewed from above. Thereby, in the state which attached the cover 30, the position of the front is aligned.

  The decorative frame 44 may be installed on the right of the cover 30 as described in the first embodiment without providing the second storage chamber 83.

  The first cookware 9 shown in FIG. 16 has an elliptical bottom surface on the inner side. The major axis dimension LS of the bottom surface is, for example, 280 mm. The maximum length of the first cooker 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 room 21.

  In addition, as shown in FIG. 16, when the first cooking appliance 9 is heated by the right side heating coil 8R, the first cooking appliance 9 is elliptical, and the major diameter dimension LS of the bottom is 280 mm. Because of this, the maximum outer diameter DA3 is too small for the 200 mm right side heating coil 8R. That is, there is a concern that both ends of the first cooking appliance 9 can not be heated sufficiently.

On the other hand, in the left heating coil 8L, as described above, the diameter of the circle surrounding the outermost sides of the four sub heating coils SC1 to SC4 is, for example, 300 mm, and in this left heating coil 8L, the bottom diameter is It can respond to the thing to be heated about 320-350 mm.
As described above, 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. As shown in FIG. 17, when the first cooking appliance 9 is on the main heating coil MC and the two sub-heating coils SC2 and SC3 on both sides across the main heating coil MC, the main inverter circuit 56LM and two The three inverter circuits 55LS2 and 55LS3 are selected by the controller 56, to which high frequency power is applied individually (simultaneously or at a time difference). Thus, for example, even when an elongated fish (for example, Akuto fish) is put in the first cooking appliance 9 and grilled, the entire bottom surface of the first cooking appliance 9 can be inductively heated. It can be heated.

  Since the left side heating coil 8L can also heat only the main heating coil MC as shown in FIG. 16, the left side heating coil 8L can cope with many kinds of metal objects to be heated which differ in size and planar shape. it can. And even if it is the 1st cooking appliance 9 formed in the shape of an ellipse or a rectangle so that a long to-be-cooked item like a sword sword fish can be cooked, according to the size of the cooking appliance, the subheating required for a drive Since the coils SC1 to SC4 can be automatically selected by the controller 56, the convenience of the user can be improved.

  Furthermore, even with such a long first cooker 9, as shown in FIG. 17, the insertion opening 22 formed on the front surface of the main body case 3 is continuously provided on the rear side from the main body case 3. Since the storage room 21 is formed inside, even the large first cooking appliance 9 can be stored.

Sixth Embodiment
FIGS. 18 to 20 show a heating cooker according to Embodiment 6 of the present invention. The sixth embodiment is characterized in that it is linked with a system for controlling the amount of electric power of the heating cooker 1. In addition, the same code | symbol may be attached | subjected to an equivalent or equivalent part to FIGS. 1-9, and the overlapping description may be abbreviate | omitted.

In the sixth embodiment, “HEMS” refers to a home energy management system, which is a system that manages power consumption in the home in an integrated manner in real time.
The “power command device” in this embodiment is a device that constitutes the core of the HEMS.

  FIG. 18 shows an example of one house using the heating cooker 1 of the present invention in a kitchen. In this figure, HA shows the living space of one house. In the living space, for example, 200 V of power is supplied from a commercial power source 60 of a power company outside the house. The power is drawn into the interior of the house via a watt-hour meter 90.

  Reference numeral 91 denotes a power supply line (main trunk line) connected to the commercial power supply 60 via a breaker BK. To the power supply line, main home appliances EE used in the house are connected. Specifically, the air conditioner 92, the lighting fixture 93, and the heating cooker 1 are respectively connected. Although only one air conditioner 92, one light fixture 93, and one cooker 1 are shown in FIG. 18, there may be a plurality.

  94 is a power control device to which power is supplied via the breaker BK, and is installed on a wall or in a place where family members can easily access it, such as a wall of a kitchen or the like, or placed on a floor surface It is

  The air conditioner 92 and the heating cooker 1 communicate information such as the required power, the menu (type) of cooking to be performed, the power to be used, and the like by wireless communication with the power command device 94, and the power command device The power consumption of the air conditioner 92 and the heating cooker 1 is controlled within the range not exceeding the upper limit power value permitted by 94. The air conditioner 92 and the heating cooker 1 are provided with the wireless communication means 68 as described in the first embodiment for wireless communication.

The air conditioner 92, the lighting fixture 93, and the heating cooker 1 are collectively referred to as "home appliances" EE.
A router 95 connects the power control device 94 and the wide area communication network 98. As a result, the power control device 94 is connected to a server of a power company outside the house or another external organization 96A. For this reason, for example, when power shortage information and the like are transmitted from an external agency 96A such as a government office or a power company in the area, the information is received by the power command device 94.

  There are at least two types of “power strain information”, a command to forcibly lower the power consumption of each home, and a command of a request level which is desired not to be forced but to be arbitrarily reduced. The power control device 94 also has a function of transmitting information acquired on the power control device 94 side (including information obtained from the home appliance EE and a command signal) to the wide area communication network 98 outside.

  An information server 96B mainly functions as a means for providing control software and a means for providing information to the home appliance EE. This information server is a household electrical appliance EE manufacturer (maker), a distributor, a repairer, or an organization such as an information service provider, a power company, or the like, installed alone or jointly by two or more organizations. It provides the user with various services related to the home appliance EE including the heating cooker 1 via the wide area communication network 98.

  The information server 96B stores application software of the home appliance EE, and is a user specifying the user of the home appliance EE and the improvement software (countermeasure program) providing unit S storing the improvement software. A database and a maker-side information database storing technical information provided by a manufacturer of the home appliance EE are provided.

The information server 96B may be generally called a "web server" (hereinafter referred to as a "web server").
The information server 96 B includes user-specific information such as a login ID and password from the power command device 94, setting information such as a network address (MAC address) of the router 95, and a specific type such as a type and model name of a specific home appliance EE. Information is stored. That is, based on the information obtained from the electric home appliance EE, for example, the heating cooker 1, the written information server 96B searches the database for storing the appropriate usage method and the caution information etc. of the heating cooker 1. Yes, with the ability to provide search results.

  The information server 27 stores “improved software” that improves the contents of the operation program of the home appliance EE corresponding to the specific model of the home appliance EE, and the power command device 94 uses the wide area communication circuit. When acquired via the network 94, the improvement software is provided to the input / output unit home appliance EE side of the power control device 94. The improvement software is not only provided once but may be provided with an improved version-up version as needed.

  In a state immediately before the heating cooker 1 is started, the power control device 94 receives, from the home appliance EE, information of the power required for the air conditioning operation, and thereafter, the operation of the heating cooker 1 is started When it comes to the stage, the required information on the required power is also received from the heating cooker 1, so the power command device 94 counts the requested power values, and the summed total power is the upper limit capacity of the breaker BK. If there is no problem from the comparison result, a permission signal is issued for the required power.

  The first time when the power command device 94 receives a power request from the home appliance EE is when the main power of the home appliance EE is turned on or when an operation start command is issued. In the heating cooker 1, after the main power switch 61 is turned ON, the heating port is selected, and a cooking menu (for example, "cooking rice" in an automatic cooking menu) is selected, or a manual cooking menu (for example, " It is the time when the heating power for boiling water is set (or at the latest, the setting of the heating power is determined and the heating operation is started).

  If the result of the transmission of the required power to the power control device 94 does not return an OK from the power control device 94 after all, the operation with the required power is not started. If an OK signal is received, driving can be started.

  In the home appliance EE, since the operation information (execution of the cooking menu, setting of the thermal power, etc.) is transmitted to the power command device 94 as needed in all processes from power on to power cut off, the power command device 94 always It is possible to grasp the power usage status of the home appliance EE.

(Basic operation of heating cooker)
Next, the induction heating operation of the heating cooker 1 according to the sixth embodiment will be described with reference to FIGS.

  The flowchart shown in FIG. 19 shows the basic operation steps of the heating cooker 1. Computer software that determines this operational step is pre-stored in controller 56.

  In FIG. 19, the user touches the operation key 14 of the main power switch 61 to turn on the power (S1). Then, power is applied to the control device 56, and the control device 56 obtains temperature information from the temperature detection circuit 63, and the main part of the heating cooker (for example, the heating coil 8, the display screen 20, and the inverter circuit board 55) A self check is made to see if the temperature is abnormally high (S2).

  If no abnormality is found, the control device 56 transmits the determination information that there is no abnormality to the power command device 94 via the wireless communication means 68.

  The control device 56 activates the drive circuit 69 of the display screen 20, and displays that there is no abnormality and that cooking can be started. At the same time, the same contents as the contents displayed on the display screen 20 by the voice synthesizer 64 are notified by voice (S3).

  Thereafter, the display screen 20 displays characters prompting the user to operate such that the object to be heated such as a metal pot is placed on the heating port to be used (S4).

At the stage of this step (S4), the display screen 20 uses characters to proceed to select whether to use the first cooking appliance 9 described above or whether to use a cooking appliance such as a common metal pan or pan. Is displayed.
Here, when the user touches the specific input key 17 in the left operation unit 12L, the user selects the heating coil 8L on the left side, and selects to use the general-purpose cooking appliances 10 and 11. Further, when another specific input key 17 in the left operation section 12L is touched, the heating coil 8L on the side is selected, and it is selected to use the first cooking appliance 9 (S5, S6).

  If it is determined in step S5 that the first cooking appliance 9 is to be used, the process proceeds to step S7 of selecting a heating menu.

  On the other hand, when it is selected to use the general-purpose cooking appliances 10 and 11 in step S6, the process proceeds to the selection step S8 of the normal cooking menu.

  If it progresses to the step (S7) which selects the menu of a heating, either roast cooking or rice cooking will be selected using the 1st cooking appliance 9 prepared specially. If the roast cooking menu is selected, the first cookware 9 is taken out of the storage room 21 and displayed on the display screen 20 so as to be placed above the left heating coil 8L, and notified by the voice synthesizer 64 as well. Ru.

  The flowchart shown in FIG. 20 shows basic operation steps in the case of performing “cooking rice” in the heating and cooking menu using the first cooking appliance 9.

In FIG. 20, S7 is a step of selecting "cooking rice" from the menu of heating and cooking.
When selection of the menu "cooking rice" is performed, predetermined start information is transmitted to the power command device 94, and it is understood that the power command device 94 is in the stage where heating and cooking are started by the heating cooker 1. (S10). Further, in the case of "cooking rice", the power consumption is determined in advance, so information of the necessary power value and operation time is transmitted to the power command device 94, for example "1400 W. Cooking time 40 minutes". (S10).

From the information server 96B to the power control device 9, information on electricity rates by time zone and reference information for cooking well (for example, when old rice is cooked, water is made to suck in advance) The information is acquired and transmitted to the heating cooker 1.
Therefore, the heating cooker 1 stores the acquired information in the internal storage device 56R (S11). In addition, since such hourly electricity rates are not changed daily, they may be acquired every few days, and the information stored in the storage device 56R is used each time for several days. Also good.

  Next, the heating cooker 1 displays the electricity rate classified by time zone acquired on the display screen 20 and the information of reference information for cooking well, and the voice synthesizer 64 gives a voice outline of the acquired information. It is notified (S12).

  In the next step (S13), it is checked whether the user is seeking more detailed information. For example, at the time of notification in the above step (S12) or by voice, guidance such as "Please touch the ○ key when detailed information is desired" is performed. In response to this, when the user performs a specific input operation at the left operation unit 12L, the process proceeds to the next step (S14).

  In the next step (S14), the heating cooker 1 requests the power command device 9 to provide details of the information acquired from the information server 96B. When all the information acquired from the information server is transmitted to the heating cooker 1, a signal indicating that there is no detailed information is transmitted from the power command device 94 to the heating cooker 1.

If there is no request for detailed information, and there is an input from the user via the input key 17 instructing the start of cooking (S15), the control device 56 drives the inverter circuit 55L to perform a predetermined cooking process (water absorption process → boiling process) → Start the unevenness process) (S16).
When the cooking process by the cooking program stored in the control device 56 is finished, the energization to the inverter circuit 55L is stopped. In addition, when performing a heat retention process succeeding to rice cooking, inverter circuit 55L is driven by small electric power rather than the time of rice cooking.

  In the above description, an example is shown for the information acquired from the power control device 94 in the case of "cooking rice", but for example, another cooking object (meat or fish) is baked by the first cooking appliance 9 Also in the case, the information of the information (for example, adjustment of the heating power of the heating coil 8L, etc.) to be used for cooking can be acquired. The end time of the heating operation may be reserved before the heating operation is started. This is generally referred to as timer cooking, and if the timer is set (for example, 15 minutes) before the start of cooking, 15 minutes are calculated from the heating start point (in the operation of the clock circuit 66 shown in the first embodiment) The heating operation is automatically ended when 15 minutes have elapsed.

Seventh Embodiment
FIGS. 21-24 shows the heating cooker based on Embodiment 7 of this invention. In the seventh embodiment, a side cover (also referred to as "end piece" or "side molding") for making the gap formed between the heating cooker 1 and the kitchen furniture 2 inconspicuous This is an example of using a cover. FIG. 21 is an enlarged vertical sectional view showing the front upper part of the heating cooker and the front upper part of the kitchen furniture according to the seventh embodiment. FIG. 22 is an enlarged vertical sectional view showing a modification of the heating cooker of FIG. FIG. 23 is an enlarged cross-sectional view showing a right cover right end portion of a heating cooker according to a seventh embodiment and a left end portion of a furniture surface material adjacent thereto. FIG. 24 is an enlarged cross-sectional view showing a modification of the heating cooker of FIG. In addition, the same code | symbol may be attached | subjected to an equivalent or equivalent part to FIGS. 1-9, and the overlapping description may be abbreviate | omitted.

  The “side cover” in this embodiment does not stand out a gap (gap) generated between the kitchen furniture 2 and the heating cooker 1 when the cooking cooker 1 of this type is installed on the kitchen furniture 2 An auxiliary component to make it In addition, the said auxiliary | assistant components used above the cooking-by-heating machine 1 and the side (right side, left side both or any one of them) are uniformly called a "side cover."

Since various side covers are conventionally proposed, they will be described first.
In Japanese Utility Model Laid-Open Publication No. 5-52611, a side cover for closing a gap formed between the installation space of the heating cooker and the outer surface of the cooker is inserted from the front into the gap and engaged with the outer surface of the heating cooker. The configuration to match is introduced. As a result, there is no need to separately provide a part for attaching the side cover, and it is supposed that the effect of reducing the number of parts and the cost can be expected.

  In JP-A-10-110957, an insertion guide is formed on the side surface of the main body case of the heating cooker (gas stove) in order to eliminate the vertical displacement when assembling the side cover and the deformation of the side cover during mounting and removal. The side cover is proposed to be detachably attached to the main case of the heating cooker.

  In addition, according to JP 2012-47411 A, a side cover whose installation work is simple and whose manufacturing cost can be reduced without spoiling the appearance even when the door of the heating chamber is opened and closed, and heating and cooking provided with this side cover Devices and their mounting methods have been proposed. In this prior art, the side cover attached to the front left side of the main body case is composed of the first part and the second part in order to hide the gap between the main body case of the heating cooker and the kitchen furniture. The first part is attached to the main body case in advance, and the second part is attached using the first part when the heating cooker main body case is stored in the kitchen furniture. As a result, it is said that the manufacturing cost can be reduced because the mounting operation is simple and no special tools or parts are required.

  Although the above-described various side covers are not described in the first to sixth embodiments described above, the effects of the present invention are affected even if the auxiliary parts for dealing with gaps such as the side covers are used. Absent. The present invention does not assume that such a side cover is not used, and may be used as needed. For example, when the side cover is finally positioned adjacent to the right of the cover 30 covering the insertion opening 22 of the storage room 21, the position of the front of the side cover does not project forward relative to the front of the cover 30 You just have to adjust the size and installation position of the side cover. In the first to sixth embodiments, the configuration of the heating cooker 1 and the kitchen furniture 2 are focused on the alignment of the front surface of the kitchen furniture 2 and the front surface of the cover 30, disregarding the presence of such side covers. I described the positional relationship and configuration of. Therefore, even though the description "the surface member 41 of the kitchen furniture 2 adjacent to the cover 30" is made, the side cover may be interposed between the cover 30 and the surface member 41.

So, in Embodiment 7, it is an example using such a side cover.
In FIG. 21, as described in the first embodiment, the GPT is 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 of the kitchen furniture 2, as shown in FIG. It is an upper air gap of about 2 cm to several millimeters (mm) formed to allow movement.

  Reference numeral 100 denotes a support protrusion provided on the upper front surface of the main body case 3 corresponding to the upper air gap GPT. This may be formed by cutting and raising a part of the main body case 3 made of sheet metal to form a claw shape, but in the example of FIG. 21, a sharp rod shape is separately formed and this is formed on the front surface of the main body case 3 It is fixed to

Reference numeral 101 denotes an upper side cover, which is entirely formed by integral molding of a plastic, or formed into a sash shape by extruding a metal material such as aluminum.
When the front surface 30F of the cover 30 and the front surface 2F of the kitchen furniture 2 have the same color, surface treatment, design, etc., the surface of the side cover 101 also conforms to these designs, improving the uniformity of the design. .

  Reference numeral 102 denotes a fitting hole formed in a hollow shape from the back side of the side cover. The side cover 101 is attached to the main body case 3 by fitting the fitting hole into the support projection 100. In addition, this side cover 101 is removed at the time of shipment of the heating cooker 1, and is inserted in the packing box which accommodated the main body case 3. As shown in FIG. Therefore, after the installer or the like installs the main body case 3 in the kitchen furniture 2, it is inserted from the outside (left direction in FIG. 21) of the opening 2B of the kitchen furniture 2 toward the tip of the support protrusion 100. .

  The cover 30 is attached to the main body case 3 from the outside (left direction in FIG. 21) of the opening 2B of the kitchen furniture 2 after the side cover 101 is attached to the main body case 3.

The length of the side cover 101 is such that it does not protrude from the front surface of the cover 30 attached later, in a state of being attached to the main body case 3 as shown in FIG.
With the above configuration, when the installation work of the heating cooker 1 on the kitchen furniture 2 is completely finished, the front surface of the cover 30, the front surface of the handle portion 31, and the side cover on the assumed vertical surface VL. All the front faces of 101 will be positioned. The front surface 2F at the top of the kitchen furniture 2 may be made to coincide with the vertical surface VL.

  In addition, since the magnitude | size of the said upper side space | gap GPT is not always constant when installed in various kitchen furniture 2, the scene which also assumes such a scene and makes the thickness of the said side cover 101 different. It may be prepared as an auxiliary component, or may be prepared as an optional item and supplied in response to an order from the user of the heating cooker 1 or an installation contractor.

  Further, a plurality of side covers 101 having different lengths may be prepared as auxiliary parts. Alternatively, during the installation work, the fixing position may be finely adjusted in the front-rear direction with respect to the main body case 3.

Next, a modification of FIG. 22 will be described.
In this modification, the length of the side cover 101 is up to a position retracted from the assumed vertical plane VL when the heating cooker 1 is installed on the kitchen furniture 2. However, even in the configuration shown in FIG. 22, when the cover 30 is moved forward and the insertion opening 22 of the storage chamber 21 is opened, the side cover 101 is in the front position substantially close to the rim of the insertion opening 22. Because of this, the presence of the upper air gap GPT diminishes. For this reason, also in the configuration of FIG. 22, it is possible to avoid largely impairing the design of the front surface of the kitchen furniture 2 due to the upper air gap GPT when the cover 30 is opened.

Next, FIG. 23 will be described.
In FIG. 23, GPR is, as described in Embodiment 1, 2 cm to several millimeters (mm) between display frame 44 and the left side of kitchen furniture 2 adjacent to the right side of heating cooker 1 The right side of the gap. In addition, when the kitchen furniture 2 is also on the right side of the heating cooker 1, there is a gap formed also between the cover 30 and the right side surface of the kitchen furniture 2, and in this case, it is called "left gap" GPL.

  Reference numeral 100 denotes a support protrusion provided at the front of the right side surface of the main body case 3 corresponding to the right air gap GPR. This is formed by cutting and raising a part of the thin metal case 3 made of a thin metal and forming it into a claw shape. Alternatively, a sharp rod-like member may be separately formed and fixed to the front or side front portion of the main body case 3.

Reference numeral 101 denotes a side cover on the right side, which is entirely formed by integral molding of a plastic, or formed into a sash by extruding a metal material such as aluminum.
When the design such as the color, surface treatment, pattern, etc. of the front surface 44F of the decorative frame 44 and the front surface 2F of the kitchen furniture 2 is unified, the uniformity of the design is improved by matching the surface of the side cover 104 with these designs. Do.

  Reference numeral 105 denotes a fitting hole formed in a hollow shape from the back side of the side cover. The side cover 104 is attached to the main body case 3 by fitting the fitting hole into the support projection 103. In addition, this side cover 104 is removed at the time of shipment of the heating cooker 1, and is inserted in the packing box which accommodated the main body case 3. As shown in FIG. Therefore, after the installer or the like installs the main body case 3 in the kitchen furniture 2, it is directed from the outside of the opening 2B of the kitchen furniture 2 (downward in FIG. 23) to the tip of the support projection 103. insert.

  The decorative frame 44 is attached to the main body case 3 from the outside of the opening 2B of the kitchen furniture 2 (downward in FIG. 23) after the side cover 104 is attached to the main body case 3.

The length of the side cover 104 is such that it does not protrude from the front surface 44F of the decorative frame 44 attached later, in a state of being mounted on the main body case 3 as shown in FIG.
With the above configuration, when the installation work of the heating cooker 1 on the kitchen furniture 2 is completely completed, the front surface 44F of the decorative frame 44 and the front surface 104F of the side cover 104 are assumed on the assumed vertical surface HL. Will be all located. The surface member 41 of the kitchen furniture 2 immediately to the right of the side cover 104 also coincides with the vertical plane VL. The vertical plane VL of FIG. 21 and the vertical plane HL of FIG. 23 are at the same position.

  In addition, since the magnitude | size of the said right side space | gap GPR is not always fixed when installing in various kitchen furniture 2, the thickness (horizontal width dimension) of the said side cover 104 was varied supposing such a scene. 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 heating cooker 1 or an installation contractor.

  Further, a plurality of side covers 104 having different lengths may be prepared as auxiliary parts. Alternatively, during the installation work, the fixing position may be finely adjusted in the front-rear direction with respect to the main body case 3.

Other Embodiments In the first to sixth embodiments of the present invention, the various side covers 101 and 104 as described above are not described, but auxiliary components for dealing with gaps such as the side covers may be used. There is no influence on the effect of the present invention. The present invention does not assume that such side covers 101 and 104 are not used, and may be used as needed. For example, when the side cover 104 is positioned adjacent to the right of the cover 30 covering the insertion opening 22 of the storage room 21, the position of the front surface of the side cover 104 is in front of the front surface of the cover 30. The size and installation position of the side cover may be adjusted so as not to protrude. In the first to sixth embodiments, the configuration of the heating cooker 1 and the kitchen furniture 2 are focused on the alignment of the front surface of the kitchen furniture 2 and the front surface of the cover 30, disregarding the presence of such side covers. I described the positional relationship and configuration of. Therefore, even if the description “the surface member 41 of the kitchen furniture 2 adjacent to the cover 30” is described, the side cover 104 may be interposed between the cover 30 and the surface member 41.

  Although in the first to sixth embodiments, the cover 30 and the decorative frame 44 are described as being attached to the main body case 3, this is always attached to the main body case 3 when the manufacturer ships the heating cooker 1. It does not mean that. In order to facilitate the installation work to the kitchen furniture 2 as shown in FIG. 9, and also to prevent the decorative parts such as the cover from hitting or damaging the kitchen furniture 2 in the process of the installation work Therefore, for example, on the front surface of the main body cover 3, a buffer material or a protection member such as a “protection sheet” or a “protection panel” which may be discarded is attached and shipped. Then, after the cooker 1 dealer or the installation company worker horizontally inserts the cooker 1 into the kitchen furniture 2 as shown in FIG. 9, the “protective sheet as described above” It is preferable to remove the “protection panel” and then attach the cover 30 or the decoration frame 44. Therefore, also in the first to sixth embodiments of the present invention, the cover 30 and the decorative frame 44 as described above, and the seventh embodiment as described above. The various side covers 101 and 104 may be put together in a packing box storing the body case 3 of the heating cooker 1 and shipped.

  In the first to fourth embodiments, the storage chamber 21 is located on the left side from the center of the main body case 3, and in the second embodiment, as shown in FIG. 10, the storage chamber is located on the left side from the center of the lower unit KU. However, this may be reversed and provided only on the right side. In addition, the storage room 21 may be formed to extend substantially the entire width of the main body case 3. For example, the storage room 21 shown in the third embodiment (see FIG. 12) may be further expanded to the right. Even in such a case, if the insertion opening 22 is opened and closed with a single cover 30, the wide storage room 21 can be opened by opening the single cover 30, and storage and removal of the cookware 9 and the like can be further performed. It will be easier.

  Further, the storage room 21 may be divided into two or more by a partition plate or a breathable net or frame so as to divide the inside into a plurality. That is, since it is sufficient that the storage room 21 can store the first cooking appliance 9, the remaining space may be used to store other cooking appliances and small accessories for cooking. Furthermore, even if the blower BM devises an air passage so as to introduce fresh air from the outside of the main body case 3 and fresh air of the lower unit KU into the inside through the inside of the storage room 21. good. When air is introduced into the storage room 21 in this manner, the storage room 21 is unlikely to be a sealed space for a long period of time, so that the occurrence of mold can also be suppressed.

  In the first to sixth embodiments, the first cooking device 9 is composed of a plate portion 9A made of magnetic metal such as stainless steel or iron, and a lid 9B made of heat-resistant glass that covers the upper side of the plate portion. However, the present invention is not limited to this configuration. For example, a lid 9B made of glass and a lid made of a metal such as a casting may be prepared in one plate portion 9A, and the user may use one according to the type of heating and cooking. A metal lid is used, for example, when the lid is easily lifted up by the pressure increase accompanying cooking such as rice cooking. That is, since the lid itself is heavy, it does not open carelessly during rice cooking.

Further, in order to lock the lid 9B to the plate portion 9A, a latch pivoted about the plate portion may be provided, and the lid 9B may be fixed so as not to open during cooking.
Moreover, the cooking appliance 9 may not necessarily have the lid 9B. Moreover, when accommodating the cooking utensil 9 in the storage chamber 21, it may not be able to put and store the lid 9B (in the same direction as the time of cooking) on the plate part 9A. For example, the lid 9B may be turned upside down and stored in that state. Although this may lower the overall height of the cooking appliance 9 and accommodate the narrow storage room 21 in some cases, it depends on the size and shape of the lid 9B and the plate 9A.

  A black ceramic coating may be applied to the entire surface of the metal plate portion 9A of the first cookware 9. Since such a ceramic coating can be expected to have a far-infrared effect, cooking and other cooking can be further heated to the inside, and a delicious dish can be made.

  It should be understood that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The substantial scope of the present invention is shown not by the above description but by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.

  The heating cooker according to the present invention can be widely used not only in kitchens of general houses but also in kitchens such as public facilities and stores.
