Abstract

<P>PROBLEM TO BE SOLVED: To increase cleaning property in a grilling chamber, and to suppress the leakage of an oil to the bottom surface section in the grilling chamber, or the entering of lamp soot. <P>SOLUTION: The adhesion of contamination in the grilling chamber (heating chamber) 501 is enclosed in a small chamber which is constituted of a top surface panel 531, side surface panels 522a and 522b, a back surface section 505 and a bottom surface section 504. All of the oil which has adhered to the lower side and the oil which has streamed down is received by a juice receiving tray 510 and the recess section 521 of an oil receiver, and accumulated. Thus, the adhesion of contamination to the wall surface of the heating chamber 501 is prevented from occurring. In addition, by making the top surface panel 531 and the side surfaces panels 522a and 522b removable, the maintenance can be facilitated. Also, since vertical surface side heaters 507 and 508 can be moved to the center in the vertical direction, the cleaning in the heating chamber becomes possible. In addition, by a forcible air discharge with a suction fan 702, the internal pressure of the small chamber is made lower, and the leakage of oil and lamp soot to the wall surface of the heating chamber 501 on the external side is suppressed. At the same time, the remaining bad odors in the heating chamber after cooking can be suppressed, and the clean state can be kept. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a heating cooker that heats an object to be cooked, and more particularly to a heating cooker with improved cleanability in a heating chamber grill.

Conventionally, various efforts have been made to solve the problem that when a fish is cooked using a grill, oil in the food being cooked scatters and the inside of the grill becomes dirty.
For example, a flat side plate that freely slides between the protrusions provided on the top and bottom surfaces of the heating chamber, also called a grill, and the side wall of the heating chamber is installed in the heating chamber, so that Even if dirt (such as fish) oil and fat or meat pieces adheres to this side plate, the side plate is not fixed, so it can be easily pulled out of the heating chamber, and can be easily washed in a kitchen sink, etc. due to its small size. The technique is disclosed (for example, see Patent Document 1).

  In addition, the cooking device is a rectangular box-shaped fixed box that is disposed in a heat-shielding case and has a front opening, and a rectangular box-shaped removable box that is detachably accommodated in the fixed box and has a front opening. If you want to clean the detachable cabinet with a double configuration, pull the door forward and pull out the roaster dish and grill net together, then grab the handle and pull the detachable cabinet forward. Thus, a technique has been disclosed in which the upper heater and the lower heater attached and fixed to the fixed cabinet side can be completely removed outside and can be easily cleaned (see, for example, Patent Document 2). .

  Also, a detachable cover plate is provided to cover each of the left and right inner surfaces of the grill cabinet, and when the cover plate is attached to each inner surface of the grill cabinet, the cover plate is held while holding the support pieces of the cover plate by hand. Is inserted into the grill cabinet from the rear end side of the grill cabinet, and finally the cover plate is moved to the inner surface side, and the cover plate locking hole is avoided while avoiding interference with the retaining ribs. To lock the lock pin of the grill. When removing the cover plate from the grill cabinet when cleaning the cover plate, etc., lift the support piece inward while slightly lifting it by hand, and remove the retaining collar from the locking hole. If it removes, the technique which can remove a cover board easily is disclosed (for example, refer patent document 3).

As shown in FIGS. 2 and 3, the grill 5 includes a heating chamber 501 that is a box-shaped case, and various components and members that are accommodated in the heating chamber 501. The heating chamber 501 includes a left side surface portion 502a, a right side surface portion 502b, a top surface portion 503, a bottom surface portion 504, and a back surface portion 505. As shown in FIG. 2, the front surface of the heating chamber 501 has a front opening 506 that is opened. It is composed. Above the heating chamber 501, an upper surface side heater 507 constituting a first radiant heat source is supported by the other end of a pair of upper surface side heater support members 5071a and 5071b having one end attached to the top surface portion 503. . Further, a lower surface side heater 508 constituting a second radiant heat source is provided below the center of the heating chamber 501, the other end of the lower surface side heater support member 5081a having one end attached to the left side surface portion 502a, and one end of the right side surface portion 502b. It is supported by the other end of the lower surface side heater support member 5081b attached to.
In addition, in the heating chamber 501, a juice tray 510 configured integrally with the door 509 of FIG. 1 is detachably mounted on left and right slide rails 511a and 511b provided to be freely movable in the front-rear direction. When the door 509 is pushed in, the soup pan 510 is completely accommodated in the heating chamber 501 and the front opening 506 is closed by the door 509. In addition, a grill net support portion 512 having a substantially U-shaped cross section is placed on the soup pan 510, and a grill net 513 on which the cooking object 80 is placed is supported by the grill net support portion 512. . Therefore, when the handle of the door 509 is grasped and pulled out, the juice receiving tray 510 and the grill 513 are also pulled out together, and the juice receiving tray 510 and the grill 513 are also stored in the heating chamber 501 together when pushed.

  The left side surface portion 502a and the right side surface portion 502b are formed with intake ports 5021a and 5021b having the same size, respectively, and intake ports 5022a and 5022b having smaller areas than the intake ports 5021a and 5021b are formed behind them. Further, sensors 5023a and 5023b are provided at the rear thereof. Further, an exhaust port 5051 is formed at the center of the back surface portion 505, and an exhaust duct 701 refracted in an L shape is provided from the exhaust port 5051 so as to contain oil smoke in the heating chamber 501. After passing through the exhaust duct 701, the air is exhausted to the outside via the suction fan 702 and the rear and upper exhaust port 7 of the main body 1.

As shown in FIG. 3, a pair of convex mounting guides 541a and 541b are formed on the bottom surface portion 504 of the heating chamber 501 in the vicinity of the left side surface portion 502a and the right side surface portion 502b in the front-rear direction. A left side panel 522a is detachably mounted in the front-rear direction along the mounting guide 541a between the left side surface portion 502a and the mounting guide 541a closer to the left side surface portion 502a. Further, an oil receiver recess 521 is provided at the lower portion of the left side panel 522a by bending inward. Further, the right side panel 522b is detachably mounted in the front-rear direction along the mounting guide 541b between the right side surface portion 502b and the mounting guide 541b closer to the right side surface portion 502b. Further, an oil receiver recess 521 is provided at the bottom of the right side panel 522b by bending inward.
The left side panel 522a is configured so that the height of the upper end portion is higher than the height of the upper surface side heater 507 when the left side panel 522a is mounted in the heating chamber 501.
In addition, a lower surface side heater 508 for heating an object to be cooked is provided between the soup pan 510 and the grill net 513.

  When the left and right side panels 522a and 522b are mounted in the heating chamber 501, the upper portions of the left and right side panels 522a and 522b are formed in an L shape so that mounting guides 5221a and 5221b projecting outward are formed. It is bent. Further, the vicinity of the ends of the mounting guides 5221a and 5221b is bent in an L shape so as to stand up to the upper end. Because of the mounting guides 5221a and 5221b, the position of the center of gravity when the side panels 522a and 522b are attached to the heating chamber 501 is located outside the center position. The panels 522a and 522b are tilted outward with the recess 521 at the lower end as a fulcrum. At this time, the mounting guides 5221a and 5221b also have a function as a stopper when the both side surfaces 502a and 502b are tilted to the left side panel 522a and the left side surface 502a as shown in FIG. 12 via the mounting guides 5221a and 5221b. Clearances are formed between the right side panel 522b and the right side panel 502b to form an air path.

Then, the top panel 531 provided in this manner so as to be detachable in the front-rear direction is inserted in the front-rear direction along the upper end of the mounting guides 5221a, 5221b bent in an L shape. It mounts so that the top | upper surface part 503 may be covered from the bottom. When the top panel 531 is placed on the mounting guides 5221a and 5221b, the top panel 531 has a function of a stopper that prevents the mounting guides 5221a and 5221b from collapsing inside, so that the side panels 522a and 522b Can maintain its position stably. At this time, a gap is formed between the top panel 531 and the top surface portion 503 to form an air path.
In the above example, the mounting guides 5221a and 5221b are formed by bending the upper portions of the left and right side panels 522a and 522b outward in an L shape. However, the mounting guides 5221a and 5221b do not have to be limited to the L shape. It may be bent outward with an inclination extending in the direction.
Even if the side panels 522a and 522b and the top panel 531 are pushed in all the way, a gap is formed between the back panel 505 and the back panel 505. This gap forms part of the air path.

Thus, the side wall and ceiling of the heating chamber 501 have a double structure, and the inside of the heating chamber 501 is a small room surrounded by the top panel 531, the left and right side panels 522 a and 522 b, the back surface portion 505, and the bottom surface portion 504 (hereinafter, , Sometimes called a small room). And by storing the upper surface side heater 507, the lower surface side heater 508, the grill net 513, and the juice receiving tray 510 in this small room, cooking can be performed in this small room, and it is generated from the food to be cooked by cooking. It is possible to confine the oily smoke and oil in the small room as much as possible, and to prevent leakage to the top surface portion 503 and the side surface portions 502a and 502b outside the small room.
Also, the oil smoke leaking into the heating chamber 501 is forcibly exhausted to the outside through the exhaust duct by the suction force of the suction fan 702, so that adhesion to the wall surfaces such as the side surface portion 502 and the top surface portion 503 of the heating chamber 501 is minimized. It is configured to reduce.

Further, as described above, the oil receiver recess 521 is provided in the lower part of the side panels 522a and 522b. Moreover, the upper part of the juice receiving tray 510 constitutes a horizontally extending flange, and the end thereof is configured to be located immediately above the recess 521 of the oil receiver. Thereby, the oil splashed by cooking adheres to any of the top panel 531, the left and right side panels 522a and 522b, the back surface 505, the juice receiving tray 510 and the recess 521 of the oil receiver, and the top surface in the heating chamber over time. Even if oil adhering to the panel 531 drips, it drops directly into the water receiving portion 510 or the oil receiving recess 521 below the side panels 522a and 522b, or travels through the side panels 522a and 522b via the mounting guides 5221a and 5221b. Therefore, oil can be prevented from adhering to the bottom surface portion 504 in the heating chamber. Further, since the vicinity of the end portions of the mounting guides 5221a and 5221b is bent in an L shape so as to stand up to the upper end portion, the oil attached to the top panel 531 hangs down on the mounting guides 5221a and 5221b. Occasionally, leakage from the mounting guides 5221a and 5221b to the outside air passage can be suppressed, and the oil can be stored in the recess 521 of the oil receiver through the side panels 522a and 522b.
On the other hand, even if the oil directly adhering to the side panels 522a and 522b drips, it accumulates in the recess 521 of the oil receiver, so that the oil can be prevented from adhering to the bottom surface portion 504 in the heating chamber.

Further, the substantially flat top panel 531 and the left and right side panels 522a and 522b constituting a small room in the heating chamber (grill warehouse) are configured to be individually removable, so that they can be washed with water with detergent or tableware. It can wash | clean using a washing machine and can improve the cleaning property in a grill warehouse further.
Moreover, if the juice receiving tray 510 is also included, all the wall surfaces of the four heating chambers can be removed, and these can be washed using a detergent or a dishwasher.

Also, a pair of lower surface side heater support members 5081a are attached to the side surfaces 502a and 502b of the heating chamber 501 at one end and horizontally support the lower surface side heater 508 (which constitutes the second radiant heat source). , 5081b are provided at the same height, and further, as shown in FIG. 5, slits 523 are formed in the side panels 522a and 522b to avoid interference with the lower surface side heater support members 5081a and 5081b. Further, the side panels 522a and 522b are configured symmetrically in the front-rear direction. As a result, even if the left and right sides of the side panel 522 are mistaken, the right and left sides of the side portion 502 of the heating chamber 501 that is the attachment destination can be appropriately selected, so that it can be inserted without any problem, and attachment is facilitated.
Further, when the side panels 522a and 522b are mounted in the heating chamber, an inclined flange 5231 is provided in the slit 523 so as to rise upward as approaching the side portions 502a and 502b of the heating chamber 501 as shown in FIG. Further, the portions near the flange 5231 of the lower surface side heater support members 5081a and 5081b are bent so as to be substantially parallel to the flange 5231. As a result, the oil adhering to the slit 523 does not drip into the outer heating chamber 501, and the adhering oil flows along the inside of the side panels 522 a and 522 b and flows down to the concave portion 521 of the lower oil receiver.
Further, with the above configuration, even if the side panels 522a and 522b are tilted inward, the flange 523 and the bent portion interfere with each other, so that the side panels 522a and 522b cannot be tilted further inward. Further, even if the side panels 522a and 522b are moved inward, the convex mounting guides 541a and 541b formed on the bottom surface portion 504 of the heating chamber 501 prevent this. Further, as described above, since the position of the center of gravity of the side panels 522a and 522b is outside the center position (on the heating chamber side), when the side panels 522a and 522b are mounted in the heating chamber, the side panels 522a and 522b themselves By tilting outward, the upper guide rail can be dispensed with.

Also, a pair of upper surface side heaters are supported so that one end is attached to the top surface portion 503 of the heating chamber 501 and the other end supports the upper surface side heater 507 (which constitutes the first radiant heat source) in a line-symmetrical manner in the left-right direction. Materials 5071a and 5071b are provided. Further, as shown in FIG. 4B, the top panel 531 is provided with slits 533 for disclosing interference with the upper surface side heater support members 5071a and 5071b. Further, the top panel 531 is configured symmetrically in the front-rear direction. Thereby, even if the left and right of the top panel 531 are mistaken, it can be mounted without worrying about the front-rear direction, and the mounting becomes easy.
In addition, when the upper surface side heater support members 5071a and 5071b are unnecessary, the slit 533 can be eliminated.
Further, as shown in FIG. 4B, when the top panel 531 is mounted in the heating chamber, an inclined flange 5331 that rises upward as it approaches the side surfaces 502a and 502b of the heating chamber 501 is formed in the slit 533. Further, the portions of the upper surface side heater support members 5071a and 5071b near the flange are bent so as to be substantially parallel to the flange. As a result, the oil adhering to the slit 533 does not sag outside the side panels 522a and 522b in the heating chamber through the top of the top panel 531, and the oil adhering to the top panel 531 is not inside the small room. Dripping into.
In addition, when the upper surface side heater support members 5071a and 5071b are unnecessary, the slit 533 can be eliminated.

The grill net 513 is also configured to be line symmetrical in the front-rear direction. Thereby, even if the right and left of the grill net 513 are mistaken, it can be mounted without worrying about the front and rear direction, and the mounting becomes easy.
Further, as shown in FIG. 6 (b), the grill net support 512, which is placed on the juice receiving tray 510 and supports the line symmetrical grill net 513, is erected in a line symmetrical position in the front-rear direction. FIG. 6A is a conventional configuration diagram, and when the support portion is erected at a biased position, there is a problem that the unsupported portion is long and the rigidity is insufficient. In addition, since the conventional grill has a complicated shape and the mounting direction is limited to one direction, it is easy to perform incorrect mounting, causing the tray not to close or the heater to be damaged. Such a problem can be solved by configuring as shown in FIG.

Moreover, FIG. 7 is a figure which shows the attachment procedure of the side panel and top panel to the heating chamber in Embodiment 1 of this invention. Next, a procedure for attaching the side panel and the top panel to the heating chamber 501 will be described with reference to FIG.

Control means for controlling the drive means to move the upper surface side heater 507 and the lower surface side heater 508 in the vertical direction toward the original position of the heating chamber may be provided.

  As described above, according to this embodiment, the top panel 531 and the side panels 522a and 522b in the heating chamber are configured to be removable, and the heater is configured to be movable up and down, so that care is facilitated.

[Exhaust flow]
In addition, as described above, the left air passage formed by the left side surface portion 502a and the left side panel 522a and the right air passage formed by the right side surface portion 502b and the right side panel 522b in the heating chamber 501 as the air passage. An air passage formed between the bottom of the juice receiving tray 510 and the bottom surface portion 504, an air passage formed between the top panel 531 and the top surface portion 503, side panels 522a and 522b, and the top panel There is an air passage formed between 531 and the back portion 505.
Further, as the intake port, the intake port formed between the lower part of the front opening 506 and the notch part of the lower part of the door 509 and the left and right side surfaces 502a and 502b are formed at least in front of the heater, preferably more forward. There are the intake ports 5021a, 50b and the left and right side surfaces 502a, 502b formed on the rear side of the heaters 5022a, 50b. Similarly, the top surface portion 503 can be provided with an intake port.
10 to 12 are diagrams showing the flow of the exhaust flow. Next, the flow of the exhaust flow will be described with reference to FIGS.
As shown in FIG. 11, the outside air taken in through the air inlet formed by the gap between the notch portion at the lower portion of the door 509 and the front opening portion 506 by the suction force of the suction fan 702 is mainly the bottom and bottom surface of the juice receiving tray 510. After the juice tray 510 is cooled while passing through the air passage between the rear portion 504 and the rear portion 504, the rear portion 505 is bent upward and collected at the exhaust port 5051 of the rear portion 505. Part of the outside air passes through the gap between the front end of the soup pan 510 and the door and the left and right gaps of the soup pan, and is surrounded by the left and right side panels 522a and 522b and the top panel 531. Together with the oily smoke and odor, it becomes exhaust gas and is collected at the exhaust port 5051 of the back surface portion 505. The outside air sucked from the intake port 5021a passes through the left air passage formed by the left side surface portion 502a and the left side surface panel 522a and proceeds rearward while cooling the left side surface panel 522a, and then turns right at the back surface portion 505. And collected in the exhaust port 5051 of the back surface portion 505. Similarly, the outside air sucked from the air inlet 5021b passes rearward while cooling the right side panel 522b through the right air passage formed by the right side part 502b and the right side panel 522b, and then turns left at the back part 505. And collected in the exhaust port 5051 of the back surface portion 505. In addition, a part of the outside air sucked from the gap between the door 509 and the front opening 506 passes through an air passage formed between the top panel 531 and the top panel 503 and cools the top panel 531 in the rear. Then, it is bent downward at the back surface portion 505 and collected at the exhaust port 5051 of the back surface portion 505. Here, the width of the gap W2 between the left and right side panels 522a and 522b, the top panel 531 and the back surface portion 505 is adjusted as appropriate for the purpose of suppressing the attachment of oil smoke to the inner wall surface of the grill. That is, it is important that the air pressure in the heating chamber (small room) becomes negative with respect to the space between the left and right side panels 522a and 522b and the top panel 531 and the inner wall surface of the grill. The gap W2 is adjusted so that the entry of oil smoke into the outer space is suppressed. The gap W2 is preferably narrower than the gap W1 between the juice tray 510 and the back surface portion 505, for example, because the cooling air for cooling the juice tray 510 must be sufficiently secured under the juice tray 510. On the other hand, it is sufficient that the gap W2 is sufficient to suppress the entry of oil smoke (a cooling effect is not essential).
Although it is not essential to provide the gap W2, the inner surface side of each panel is the outer surface side in consideration of the manufacturing error, the case where the gap W2 has occurred, such as when the insertion of each panel is not complete, etc. The configuration is such that negative pressure is achieved.
A part of the outside air leaks from the top panel 531 and the mounting guides 5221a and 5221b at the top of the side panel and flows into the small room. The airflow suppresses leakage of oil from the small chambers to the outside in the mounting guides 5221a and 5221b.
Furthermore, as shown in FIG. 10, the outside air from the upper air passage can be taken in through the slit 533 provided in the top panel 531 and the oily smoke can be efficiently removed backward. Note that the airflow suppresses leakage of oil from the small chamber to the outside in the slit 533.
In this way, all the exhaust gas is collected at the exhaust port 5051, guided from the exhaust port 5051 through the exhaust duct 701 and the suction fan 702 to the upper rear exhaust port 7, and then discharged from the exhaust port 7 to the outside. The

Note that the exhaust port 5051 does not reduce the effect of suppressing the intrusion of oil smoke at the front portion of the grill by sucking a lot of air from the intake port 5022a close to the exhaust port 5051 and reducing the inflow of air from the farther intake port 5021a. The diameter of the intake port 5022a close to may be made smaller than the diameter of the farther intake port 5021a.
Further, a catalyst is provided in the exhaust duct 701, where unpleasant odor components are captured. In addition, the odor component captured by the catalyst can be thermally decomposed by operating a heater provided in the vicinity as needed.
Furthermore, as shown in FIG. 10, the air from the left and right air passages can be taken in through the front slits 523 provided in the side panels 522a and 522b, and the oily smoke can be efficiently removed rearward. Note that this air flow suppresses leakage of oil from the small chamber to the outside in the slit 523.
In addition, there is a problem that turbulent flow is generated in the rear corners of the small room, that is, the inner portions behind the left and right side panels 522a and 522b and the rear inner portions of the top panel 531 so that a part of the oil smoke tends to stay. However, the rear slit efficiently removes the accumulated oily smoke to the exhaust port. In addition, it is possible to further improve the efficiency of removing the oil smoke accumulated by the outside air sucked from the intake ports 5022a and 5022b provided behind the left and right side surfaces 502a and 502b.
In the above-described embodiment, the air inlet is provided in the side surface portion 502 and the top surface portion 503 of the grill 5, but this air inlet is not essential, and a slight gap at the joint between the side surface portion 502 and the top surface portion 503 is provided. From the front side of the side surface portion 502 or the top surface portion 503 of the grill 5 and the door 509.
Further, the cooling air for cooling the bottom surface of the juice receiving tray 510 is not only flowed from the front to the rear, but also flows from the rear to the front, so that there is a sufficient gap between the front end of the juice receiving tray 510 and the door 509. The air discharged from the air may flow into the small room and be discharged to the rear exhaust port 5051. In that case, the air path formed between the bottom of the juice receiving tray 510 and the bottom surface portion 504 may have a shape between the bottom of the juice receiving tray 510 and the bottom surface portion 504 as shown in FIG. A plate on which the bottom surface of the juice receiving tray 510 is brought into contact with or placed thereon may be provided, and an air path may be formed by this plate and the bottom surface portion 504. If the bottom surface temperature of the soup pan 510 can be kept below the ignition point of oil, it is not necessary to fill the soup pan 510 with water for preventing ignition, so that a so-called waterless grill can be formed.

In the case of a sensor using reflected light, a sensor 5023a for detecting the presence or absence of the left side panel 522a is provided on the left side surface portion 502a of the heating chamber 501, and a sensor 5023b for detecting the presence or absence of the right side panel 522b is provided on the right side surface portion 502b.

A circuit 1304 and a display unit 1304 for displaying an alarm are included.
FIG. 14 is a flowchart showing the operation when the presence or absence of the side panel and the top panel is detected in the embodiment of the grill according to the present invention.
Next, the operation when the presence or absence of the side panel and the top panel is detected will be described with reference to the flowchart of FIG. 14. When the user turns on the power switch, the grill is activated and the control unit 1301 starts the operation.
First, the control unit 1301 acquires detection information from the sensor of the left side panel 522a (step S1401), and then determines the presence or absence of the left side panel 522a based on this information (step S1402). If not, the heater drive circuit is controlled to cut off the energization of the upper surface heater 507 and the lower surface heater 508 to stop the operation (step S1403), and an error display (alarm output) is performed (step S1404). If it is determined in step S1402 that the left side panel 522a is present, detection information is acquired from the sensor of the right side panel 522b (step S1405), and then the presence or absence of the right side panel 522b is determined based on this information (step S1405). S1406). If not, the heater drive circuit is controlled to cut off the energization of the upper surface heater 507 and the lower surface heater 508 to stop the operation (step S1403), and an error display (alarm output) is performed (step S1404). If it is determined in step S1406 that the left side panel 522a is present, detection information is acquired from the sensor of the top panel 531 (step S1407), and then the presence or absence of the top panel 531 is determined based on this information (step S1407). S1408). If not, the heater drive circuit is controlled to cut off the energization of the upper surface heater 507 and the lower surface heater 508 to stop the operation (step S1403), and an error display (alarm output) is performed (step S1404). If it is determined in step S1408 that the left side panel 522a is present, the heater drive circuit is controlled to energize the upper surface side heater 507 and the lower surface side heater 508 (step S1409).

Note that any sensor system such as a mechanical contact system or an optical system may be used.
For example, the sensor may be constituted by a mechanical button switch. In this case, as shown in FIG. 4A, the button switches 100a and 100b are provided at the mounting position of the side panels 522a and 522b or the mounting position of the top panel 531 of the bottom surface portion 504 of the heating chamber 501. Accordingly, when the side panels 522a and 522b and the top panel 531 are mounted in the heating chamber 501, the button switch is pressed by the weight thereof to turn on the contact points, so that the side panels 522a and 522b or the top panel 531 are present. Can be detected.
Moreover, you may comprise a limit switch instead of a switch. In this case, magnets are embedded in the end portions of the side panels 522a and 522b, and a limit switch is provided in the vicinity of the side panel installation position of the bottom surface portion 504 of the heating chamber 501. Thus, when the side panels 522a and 522b are mounted in the heating chamber 501, the control unit 1301 can detect that the side panels 522a and 522b are mounted by turning on the limit switch with the magnetic force of the magnet. . If it remains off, it is determined that control unit 1301 is not attached.
Further, the sensor may be configured by an optical type including a light emitting unit and a light receiving unit. In this case, as shown in FIGS. 11 and 12, a pair 5023a, 5023b, 5031 of a light emitting portion and a light receiving portion is provided on each of the side surface portions 502a, 502b and the top surface portion 503 of the heating chamber 501. That is, when the side panels 522a and 522b and the top panel 531 are attached to the side surfaces 502a and 502b and the top panel 503, the light emitted from the light emitting unit is emitted from the side panels 522a and 522b or the top panel. The positions of the light emitting unit and the light receiving unit, the irradiation direction, and the light receiving direction are set so that the reflected light is received by the light receiving unit 531. Thereby, the presence or absence of the side panels 522a, 522b or the top panel 531 can be detected based on whether the light receiving unit has received the reflected light.

Further, the light emitting unit is attached to one side surface 502 of the heating chamber 501, the light receiving unit is attached to the other side surface 502 of the heating chamber 501, and the side panel 522a is detected by detecting whether or not the light reception of the light receiving unit is blocked. The presence or absence of 522b can also be detected.
Further, the sensor may be constituted by a capacitor (capacitance detector). In this case, the condenser is provided at the side panel installation position of the bottom surface portion 504 of the heating chamber 501. In addition, a value between the capacity when the side panels 522a and 522b are not present and the capacity when the side panels 522a and 522b are present is set as a threshold, and the presence or absence of the side panels 522a and 522b or the top panel 531 is compared with this threshold. Can be detected.
The sensor may be an electromagnetic sensor. That is, an electromagnet that generates an alternating magnetic field and a current detector are provided in pairs at the side panel installation position of the bottom surface portion 504 of the heating chamber 501. The amount of change in the electromagnetic field when the side panels 522a and 522b are attached to the heating chamber 501 is different from the amount of change in the electromagnetic field when the side panels 522a and 522b are not attached to the heating chamber 501. The presence or absence of the side panels 522a and 522b can be detected by setting a value between the change amounts as a threshold value and comparing the change amount of the current detected by the current detector with the threshold value.
Further, the side panels 522a and 522b and the top panel 531 are made of a conductive material and insulated from the surroundings at any position on either the left or right side of the position where the left and right side panels 522a and 522b of the bottom surface portion 504 are mounted. A negative electrode that is provided with a positive electrode and is insulated from the surroundings is provided at an arbitrary position where the side panels 522a and 522b are mounted in the same manner as the other. In addition, an insulating material is applied to portions other than the portion corresponding to the electrode at the lower end of the side panels 522a and 522b. A power source and a current detector are connected to the positive electrode and the negative electrode. With this configuration, when the conductive side panels 522a and 522b and the top panel 531 are mounted in the heating chamber, the power source, the positive electrode, the side panels 522a and 522b, the top panel 531 and the side panel 522a 522b, the negative electrode, the current detector, and the power supply are configured in this order, and thus a current flows through the current detector. Therefore, the presence / absence of the side panels 522a and 522b and the top panel 531 can be detected at the same time depending on whether or not the current detector detects a current.

  As described above, according to this embodiment, the adhesion of dirt in the grill box (heating chamber) 501 for grilled fish used in an IH cooking heater, a gas stove, etc., is removed. The top panel 531, the side panels 522 a and 522 b, and the back section 505. The oil trapped in the small chamber constituted by the bottom portion 504 and the oil adhering to the bottom or the oil that has flowed down are received and stored in the juice receiving tray 510 and the recess 521 of the oil receptacle, thereby collecting the wall surface (the bottom portion 504 and the side surface of the heating chamber 501). By attaching the top panel 531 and the side panels 522a and 522b to each other, it is possible to easily perform maintenance. Moreover, since the upper and lower surface side heaters 507 and 508 can be moved to the center in the vertical direction, the heating chamber can be cleaned. Furthermore, since the internal pressure of the small room is lowered by forced exhaust by the suction fan 702, oil and soot are prevented from leaking to the wall surface of the outer heating chamber 501, and a bad smell is stained in the heating chamber after cooking. It becomes possible to maintain suppression and a clean state. In this way, generation of oil and smoke during cooking is also suppressed, and cooking can be performed more deliciously.
