In the electromagnetic cooking device of the present embodiment, the food in the cooking chamber 8 is heated by the heater 26, but when the temperature in the cooking chamber 8 is detected by the thermistor 192 and the cooking chamber 8 becomes hot, Heating by the heater 26 is prohibited. A thermistor is also arranged behind the convex portion 190L, and the thermistor detects the presence or absence of water in the tray 11 through the convex portion 90H of the grill case and the concave portion 11A of the tray 11. That is, when water is present in the tray 11, the temperature detected by the thermistor behind the convex portion 190 </ b> L does not rise to 100 ° C. or higher, but when water runs out, the temperature detected by the thermistor increases to 100 ° C. or higher. By detecting this temperature difference, the presence or absence of water in the tray 11 is detected.

  Next, referring to FIG. 5, grill case 90 is a housing having a bottom surface, left and right side surfaces, a top surface, and a rear surface. However, the rear surface is lower than the side surface and is not connected to the upper surface. At the center of the upper surface of the grill case 90, a rear end portion is opened, and a slot 90X extending in the front-rear direction is formed. With such a configuration, the upper surface of the heater 26 closest to the heater 26 among the wall surfaces constituting the cooking chamber 8 can be covered with the upper surface of the grill case 90 excluding the slit 90X. The wall surface of the grill case 90 is formed with a plurality of convex portions that are convex inward by being seated.

  Next, referring to FIG. 6, the tray 9 includes a door 10, a handle 13, and a tray 11. A concave portion 11 </ b> A having a convex shape on the outside is formed at the bottom rear portion of the tray 11. In addition, a concave portion 11D is formed on the left side of the concave portion 11A, and a concave portion of the same type as the concave portion 11D (not shown in FIG. 6, corresponding to a convex portion 11E described later) is formed on the right side.

  Next, referring to FIG. 7, the grill case 90 is accommodated in the roaster housing 19, and the tray 11 is accommodated in the grill case 90. The opening at the front of the roaster housing 19 is blocked by the door 10. In FIG. 7, the right side surface of the roaster housing 19 and the grill case 90 is omitted to show the inside of the grill case 90.

  When the grill case 90 is housed in the roaster housing 19, the heater 26 is positioned inside the grill case 90. The grill case 90 is fitted from the front of the roaster housing 19 and is housed in the roaster housing 19. At this time, the fixture 26A is passed through the slit 90X from the rear side opening of the slit 90X. That is, in the state shown in FIG. 7, the fixture 26A supports the heater 26 in the grill case 90 through the slit 90X.

  In addition, the grill case 90 constitutes the inner wall of the cooking chamber, but the grill case 90 can be detached from the roaster casing 19 in the heating cooker of the present embodiment. Therefore, the oil content, odor components, and food fragments stuck to the wall surface of the grill case 90 can be cleaned not only by wiping off as in the past, but also by rinsing with tap water in a kitchen sink, for example. Therefore, the grill case 90 can be easily and neatly cleaned. Further, the portion of the grill case 90 that covers the upper surface close to the heater 26 is likely to be baked with food oil, odor components, and food fragments by the heat of the heater 26, but can be washed away by removing the grill case 90 from the main body 1. Therefore, it is possible to suppress the generation of a strange odor from the grill case 90.

  In FIG. 7, the convex part 11E currently formed in the rear part of the tray 11 of the tray 9 is shown. In a state where the tray 9 is stored in the grill case 90, the convex portion 11E is caught by the convex portion 90K. In addition, the portion that protrudes toward the lower surface side of the saucer 11 that constitutes the recess 11 </ b> D of the saucer 11 is also hooked by the same convexity as the convexity 90 </ b> K on the bottom of the grill case 90. By these catches, the tray 9 is fixed in the grill case 90. When the tray 9 is pulled forward, the user shifts the rear end of the tray 11 slightly upward so that the lower end of the convex portion 11E is positioned higher than the upper end of the convex portion 90K, so that the convex portion 11E A catch such as a catch on the convex portion 90K can be released.

  The door 10 and the tray 11 are connected by connecting members 11B and 11C. Further, in a state where the grill case 90 is housed in the roaster casing 19, the convex portions on the back surface side of the concave portions 90A and 90B (referred to as convex portions 90A and 90B) are caught on the convex portions 190J and 190K, respectively. . These catches are released by moving the front of the grill case 90 upward.

  A leaf spring 193 is attached inside the upper surface of the roaster housing 19. On the upper surface of the grill case 90, a convex portion 90L having a convex shape on the outside is formed. In a state where the grill case 90 is housed in the roaster housing 19, the convex portion 90 </ b> L is pressed by the rear end of the leaf spring 193. Note that by pressing the leaf spring 193 upward, the pressing of the convex portion 90L by the rear end of the leaf spring 193 is released. That is, the grill case 90 is pressed and fixed to the roaster housing 19 by the leaf spring 193. The leaf spring 193 is not limited to this, and can be applied to any urging member that presses the grill case 90. Further, an urging member having the same action as the leaf spring 193 may be provided on the grill case 90 side. In other words, the urging member provided in the grill case 90 may be configured to be fixed to the roaster housing 19 by pressing the roaster housing 19.

  Further, in a state where the grill case 90 is housed in the roaster housing 19, the flanges 92 and 93 are urged downward by the convex portions 190C and 190D, respectively. The bias is released by moving the rear end of the grill case 90 downward.

  The above-described flanges 92 and 93 have a function of preventing the grill case 90 from being tilted forward by engaging with the convex portions 190C and 190D. That is, the grill case 9 is configured to be detachable with respect to the roaster casing 19 and has a structure with a certain amount of shakiness. The tray 9 is not pulled out from the grill case 9 when food is placed on the net shelf placed on the tray 11 or turned over, and is fixed in a state of being pulled forward with respect to the user. Work such as turning it over.

  Therefore, when the tray 9 is pulled forward, the load of the tray 9 is applied to the front of the grill case 90. Therefore, the grill case 90 tries to rotate around the lower portion of the roaster casing 19 near the front plate 190. The power to do is added. When the grill case 90 itself tilts so as to lower the front by this force, the tray 9 is tilted forward more than necessary, and the tray 9 slides down from the grill case 90, or the water in the tray 11 does not slide down. There is a risk of spilling. In order to avoid such a situation, the flanges 92 and 93 are engaged with the lower portions of the convex portions 190C and 190D of the roaster housing 19 to prevent the grill case 90 from being inclined.

  That is, the projecting portions 90A and 90B, the projecting portions 190J and 190K, the projecting portion 90L, the leaf spring 193, the flanges 92 and 93, and the projecting portions 190C and 190D, the case member (grill case 90) is grilled. A fixing member for removably fixing to 19) is configured.

  Further, the convex portions 90C and 90D on the bottom surface of the grill case 90 and the convex portions 190G and 190H on the bottom surface of the roaster housing 19 are not in the same position in the vertical direction. Thus, an air layer is formed between the bottom surface of the grill case 90 and the roaster housing 19 by the height of the convex portions 190G and 190H.

  Further, the convex part 90F on the right side of the grill case 90 and the convex part 190F on the right side of the roaster housing 19 are not in the same position in the horizontal direction, and the convex parts 90E and 190E on the left side are also in the same position in the horizontal direction. Not. Thus, air layers are formed in the left and right directions of the grill case 90 and the roaster casing 19 by the horizontal dimension of the convex portions 190E and 190F, respectively. The convex portions 190E, 190F, 190G, and 190H described above function as positioning members when the grill case 90 is housed in the roaster housing 19.

  The convex portions 90 </ b> C, 90 </ b> D, 90 </ b> E, and 90 </ b> F each function as a rail when the tray of the tray 9 is stored in the grill case 90.

  A silicon rubber 10A is attached to the upper end of the door 10 on the back side (the side on which the tray 11 is attached) so as to extend in the horizontal direction so as to correspond to the recess 190A. When the door 10 is in a state of closing the cooking chamber 8, that is, when the tray 11 of the tray 9 is stored in the grill case 90, the silicon rubber 10A contacts the recess 190A. As a result, it is possible to reliably avoid leakage of smoke and the like generated during cooking in the cooking chamber 8 from above the door 10. Smoke or the like generated in the cooking chamber 8 is discharged from the upper rear portion of the grill case 90 to the outside of the main body 1 through the discharge pipe 191 attached to the rear surface side of the roaster housing 19 and the exhaust hole 7. The

  FIGS. 8-11 is a figure which shows the 1st modification of the fixing mechanism (hooking of the convex part 11E and the convex part 90K) of the saucer 11 rear part and the grill case 90 rear part demonstrated using FIG. .

  Referring to FIG. 19, the second control unit 34 has an outer shape that is rectangular in cross section and is covered with a unit case 38 made of heat-resistant resin that serves as an air duct. The inside of the unit case 38 is separated in the vertical direction by a separation plate 39. A circuit board 40 on which circuit components such as a diode bridge are placed is fixed on the separation plate 39. A circuit board 41 on which a microcomputer for driving control of the inverter is mounted is fixed below the separation plate 39.

  Ventilation holes such as ventilation holes 38A and 38B are appropriately formed on the side surface of the unit case 38. Further, the front surface and the upper surface of the unit case 38 can be separated from the other surfaces of the unit case 38 as a lid member 43. The structure of the lid member 43 will be described in detail with reference to FIG. 20A is a plan view of the lid member 43, FIG. 20B is a cross-sectional view taken along line BB in FIG. 20A, and FIG. 20C is a front view of the lid member 43. It is.

  The lid member 43 is mainly composed of a portion constituting the upper surface of the unit case 39, and includes a front surface portion 42 constituting the front surface of the unit case 38 and a protruding portion 44 which is a portion protruding like a eaves at the rear portion of the unit case 38. Is connected.

  The lid member 43 is formed with a plurality of holes 43A, 43B, and 43C. A wall 43E is attached to the rear end of the lid member 43. The dimension of the wall 43E in the left-right direction (corresponding to the up-down direction in FIG. 20A) is the same as the dimension of the lid member 43. A large portion of the front surface portion 42 is formed with a hole 42A.

  The projecting portion 44 that is the rear portion of the lid member 43 and is located behind the wall 43E is inclined downwardly from the portion connected to the lid member 43 toward the rear (rightward in FIG. 20). Furthermore, ribs 44A, 44B, 44C, 44D, 44E, and 44F are attached to the protrusion 44.

  With further reference to FIGS. 1 and 3, the wind sent from fan 35 is introduced into unit case 38 through hole 42A. The wind introduced into the unit case 38 is separated up and down by the separation plate 39 and is discharged out of the unit case 38 through the vent holes 38A and 38B and the holes 43A, 43B and 43C.

  The rear portion of the unit case 38 faces the exhaust hole 7. Even when moisture enters the main body 1 through the exhaust hole 7, the protrusion 44 is provided at the rear of the unit case 38, so that the moisture does not enter the unit case 38. Immediately, it is guided downward along the inclination of the protrusion 44. Further, since the ribs 44 </ b> A to 44 </ b> F are attached to the projecting portion 44, the moisture that has entered can be guided more quickly away from the unit case 38.

  Furthermore, since the wall 43E is attached to the upper part of the unit case 38, even when an elongated object such as a wire is inserted into the main body 1 from the exhaust hole 7, the object can be blocked by the wall 43E. Therefore, the wall 43E can surely avoid the intrusion of foreign matter into the back of the main body 1.

  The moisture guided downward along the projecting portion 44 is discharged downward from the main body 1 through a discharge hole provided in the bottom surface of the main body 1. The heater 26 is not limited to a radiant heater, and includes all heat sources for heating food such as a metal plate heated by induction heating and cooked with heat generated from the metal plate. In the present invention, the heat source is called a heater. Further, in the present invention, the tray 9 corresponds to a mounting member, the roaster housing 19 corresponds to a grill cabinet, the grill case 9 corresponds to a case member, and the unit case 38 corresponds to a control box.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
