An outer frame 2 is attached to the upper part of the main body case 1, an operation panel 3 is attached to the front part of the outer frame 2, and an exhaust port panel 5 having an exhaust port 4 is attached to the rear part of the outer frame 2.

  A top plate (not shown) is mounted on the outer frame 2 between the operation unit panel 3 and the exhaust port panel 5. The top plate is made of heat-resistant tempered glass, and printed on the back surface so that the inside cannot be seen. On the surface of the top plate, a left heating port, a right heating port, and a central heating port indicating the mounting position of the pan are displayed by a method such as printing.

  Below the top plate, a left heating coil 6, a right heating coil 7, and a central heating coil 8 are arranged facing the left heating port, the right heating port, and the central heating port, respectively. The left heating coil 6 and the center heating coil 8 are fixed on the horizontal partition plate 9, and the right heating coil 7 is fixed on the substrate case 10 by the support portion 11.

The board case 10 is provided with blowing ports 10a, 10b, and 10c for blowing cooling air from the fan unit 12 upward (see FIG. 4). The cooling air blown upward from the blowout ports 10a, 10b, and 10c first cools the right heating coil 7, and then is discharged to the outside from the exhaust port 4 while cooling the left heating coil 6 and the central heating coil 8. The

  An opening 13 for detachably storing the grill 200 in the main body case 1 is provided, for example, on the left front surface of the main body case 1. Further, a door 14 for opening and closing the front surface is attached to the front surface of the main body case 1. When the substrate case 10 is provided on each side (left and right) of the main body case 1, an opening 13 is provided in the center of the front surface of the main body case 1, and spaces are formed on both sides of the opening 13. The grill 200 is accommodated in the main body case 1. When the substrate case 10 is provided on the left side of the main body case, an opening 13 is provided on the right side of the front surface of the main body case 1, and the grill 200 is provided with a space 13 a on the left side of the opening 13. Store in the case 1.

  The aforementioned door 14 is made of, for example, ABS resin, and is attached to be rotatable about a hinge portion (not shown) provided at the lower part of the front surface of the main body case 1. The reason why the ABS resin can be used for the door 14 is that, as will be described later, when the grill 200 is used for cooking, it is taken out from the main body case 1 and used. That is, the main body case 1 is not heated by the grill 200. Further, in the cooking device 100 in the system kitchen, when the door 14 is made of ABS resin, the design of the system kitchen can be coordinated with the design of the system kitchen as a whole.

  A recess 14 a that covers the opening 13 is formed on the back surface of the door 14 that faces the opening 13. In the recess 14a, for example, an open portion 14b having a lower portion opened is provided. In addition, although it described that the open part 14b was provided in the lower part of the recessed part 14a, you may provide the open part 14b in the left side among the sides of the recessed part 14a. Moreover, when the opening part 13 is provided in the right side of the main body case, you may provide the open part 14b in the right side among the lower part of the recessed part 14a, or the side of the recessed part 14a.

  The aforementioned grill 200 has a space 13 a on the side of the substrate case 10 in the opening 13 and is detachably accommodated inside the main body case 1. That is, for example, the grill 200 is installed on the left side of the opening 13 when the main body case 1 is viewed from the front. The grill 200 includes, for example, a main body 200a having an upper opening, a cover 200b attached to the rear of the main body 200a so that the upper portion can be opened and closed, an operation unit 200c provided on the front surface of the main body 200a, a bottom surface of the main body 200a, A heater (not shown) having a power supply of 100 V mounted on the back surface of the cover 200b and a grill plate and a grill net detachably provided inside the main body 200a are provided.

  When cooking the cooked food using the grill 200, the grill 200 is taken out from the main body case 1 through the opening 13 and installed in another place, and a power cord prepared in advance is connected to the outlet and the main body 200a. And after putting a foodstuff in the main body 200a, the operation part 200c is operated and the foodstuff in the main body 200a is heated.

  When cooking the cooked food using the grill 200 in this way, the grill 200 can be used in another place other than the heating cooker 100, so that the restriction on the power consumption is reduced as compared with the heating cooker 100 with a built-in grill. Thus, the cooling device for the grill 200 is not necessary, and a heat shield for shielding heat radiation when the grill 200 is used is not necessary. Further, the grill 200 prevents the top plate from becoming hot. Since the grill 200 is detachable from the main body case 1, it becomes easy to replace the old grill 200, leading to the expansion of the rental property market.

  A vertical partition plate 15 is provided between the grill 200 and the substrate case 10. The vertical partition plate 15 stands upright from the bottom surface 1 a of the main body case 1 and is joined to the horizontal partition plate 9 described above. An intake port 15 a made up of a plurality of holes is provided on the inner surface of the vertical partition plate 15. In the main body case 1, a grill storage 16 for storing the grill 200 is formed by the horizontal partition plate 9 and the vertical partition plate 15.

  When the grill 200 is stored in the grill storage 16, an air passage 17 is formed between the side surface of the grill 200 and the vertical partition plate 15. The air passage 17 is only when the grill 200 is stored in the grill storage 16 as described above. In this state, the air passage 17 communicates with the space 13 a formed in the opening 13. When the grill 200 is taken out from the grill storage 16, the grill storage 16 serves as an air path.

The flow of the cooling air when the fan unit 12 is driven in the cooking device configured as described above will be described.
When the grill 200 is stored in the grill storage 16, for example, when a high frequency current is supplied to the right heating coil 7 and heating of the pan placed on the right heating port is started, it is provided in the fan unit 12. The selected cooling fan is driven. At this time, outside air is sucked in as cooling air from the opening 14b provided in the recess 14a of the door 14. And most of the cooling air flows from the space 13a between the grill 200 formed in the opening 13 and the opening 13, flows into the air passage 17 communicating with the space 13a, passes through the air inlet 15a, and the fan unit 12. It is sucked in.

  The sucked cooling air is sent into the substrate case 10 by a cooling fan, and blown upward from the air outlets 10a, 10b, and 10c while cooling the circuit board. Cooling air from the outlets 10a, 10b, and 10c cools the right heating coil 7, and then is discharged to the outside from the exhaust port 4 while cooling the left heating coil 6 and the central heating coil 8.

  If the cooling fan provided in the fan unit 12 is driven when the grill 200 is not installed in the grill storage 16, the outside air is used as cooling air in the recess 14a of the lid 14 as described above. It is sucked from the provided open part 14b. Then, the cooling air flows into the grill storage 16 through the opening 13 and is sucked into the fan unit 12 through the intake port 15a.

  The sucked cooling air is sent into the substrate case 10 by a cooling fan, and blown upward from the air outlets 10a, 10b, and 10c while cooling the circuit board. Cooling air from the outlets 10a, 10b, and 10c cools the right heating coil 7, and then is discharged to the outside from the exhaust port 4 while cooling the left heating coil 6 and the central heating coil 8.

  As described above, in the present embodiment, the opening 14b for sucking outside air is provided in the recess 14a of the door 14, and the intake air communicating with the fan unit 12 on the back surface of the vertical partition plate 15 attached in the main body case 1 is provided. An opening 15a is provided to take outside air into the main body case as cooling air. With this configuration, noise caused by cooling air can be suppressed as compared with a conventional cooking device having an air inlet near the fan unit 12. In addition, since the air inlet 15a is provided in the main body case, even if the food in the pan overflows on the top plate, it does not flow into the main body case 1 and prevents the circuit board from being damaged due to the overflow. it can.

  In addition, some conventional cooking devices built into the system kitchen have an air inlet on the back and bottom of the main body case, but the bottom air inlet is blocked by the cooking utensil stored below the kitchen table. In addition, in the heating cooker according to the present embodiment, the intake port 15a is provided in the main body case 1 as described above. Therefore, the intake port 15a is not blocked, and the air volume necessary for cooling can be sucked.

  In the present embodiment, it has been described that the vertical partition plate 15 is provided between the grill 200 and the substrate case 10, and the air inlet 15 a communicating with the fan unit 12 is provided on the inner surface of the vertical partition plate 15. However, the vertical partition plate 15 may not be provided. In that case, the cooling air sucked into the grill storage 16 is directly taken into the fan unit 12 to cool the circuit board and the heating coils 6, 7, 8.
