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.
[0059]
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.
[0060]
  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 90Is a structure that is detachable from the roaster housing 19 and has a certain amount of shakiness. When the tray 9 is placed with food on a net shelf placed on the tray 11 or turned over, the grill case 90The work is not pulled out, is fixed in a state of being pulled forward with respect to the user, and is turned over.
[0061]
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.
[0062]
That is, the projecting portions 90A and 90B, the projecting portions 190J and 190K, the projecting portions 90L, the leaf springs 193, the flanges 92 and 93, and the projecting portions 190C and 190D, the case member (grill case 90) can be grilled (roaster housing). A fixing member for removably fixing to 19) is configured.
[0063]
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.
[0064]
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.
[0065]
The convex portions 90C, 90D, 90E, and 90F function as rails when the trays of the tray 9 are stored in the grill case 90, respectively.
[0066]
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
[0067]

Here, the configuration of the second control unit 34 will be described in detail. The first control unit 32 has the same configuration as the second control unit 34. FIG. 19 is a diagram schematically showing the inside of the main body 1. FIG. 19 is a schematic cross-sectional view taken along the line AA in FIG. 1, and is a diagram schematically showing the inside of the main body 1 as viewed from the left.
[0080]
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.
[0081]
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.
[0082]
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.
[0083]
The lid member 43 has 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.
[0084]
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.
[0085]
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 discharged out of the unit case 38 through the vent holes 38A and 38B and the holes 43A, 43B and 43C.
[0086]
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 protruding portion 44, the moisture that has entered can be guided more quickly away from the unit case 38.
[0087]
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.
[0088]
  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 and cooked by 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 is a mounting member, the roaster housing 19 is a grill cabinet, and a grill case 9.0Is a case member, and the unit case 38 is a control box.
[0089]
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.
