Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric cooking heater having a cooling structure.

[0002]

2. Description of the Related Art Conventional electric cooking heaters generally have a plurality of heating portions on the upper surface of the main body and a grill portion for grilling fish, etc. When the temperature is high, the control unit and main unit case are likely to get hot, especially for built-in types that are built into the system kitchen, the temperature of the system kitchen rises due to the heat of the grill, and the heat-resistant temperature of the wood is exceeded. Therefore, the grill part may be covered with a heat insulating material, and the outside of the heat insulating material may be covered with a metal plate to insulate the grill part to keep the temperature outside the grill part low (for example, see Japanese Utility Model Laid-Open No. 4-1305). There is one that is provided with a cooling fan or a duct to cool the control device section and the main body case section (for example, see Japanese Utility Model Laid-Open No. 3-71597).

[0003]

In the conventional electric cooking heater described above, in order to lower the temperature of the control unit and the main body case, a heat insulating material around the grill, a member for covering the heat insulating material, and a mounting member for mounting the heat insulating material are attached. Etc., or the number of parts such as the cooling fan and the duct dedicated to the control device and their mounting members increases, the number of assembling steps increases, and the main body becomes large.

The present invention is intended to provide an electric cooking heater capable of cooling the heat of the grill portion with a simple structure.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and comprises a plurality of heating portions on the upper surface of the main body, and a grill portion on the half of the main body below these heating portions. In an electric cooking heater having a heating unit and a control unit for controlling energization to a grill unit in the other half, a partition plate for blocking the grill unit and the control unit is provided inside the main body, and the grill divided by this partition plate. A cooling fan to release the hot air of the unit is provided at the rear of the grill, a wind tunnel is provided to cover the grill, and a lower surface air intake for cooling the control unit, which is also divided by a partition plate, is provided on the front lower face of the control unit. In addition to installing the control unit exhaust port at the rear upper part of the control unit, the common front air intake between the system kitchen and the main unit, the front air intake at the lower front of the main unit Those having respectively a bottom opening placed.

[0006]

With the electric cooking heater of the present invention having the above-mentioned structure, the wind tunnel covering the grill portion prevents the heat of the grill portion, which has a high temperature, from radiating heat, and the cooling fan efficiently discharges the heat of the grill portion. Discharge well. Further, the partition plate prevents heat of the grill portion from flowing into the control device unit, and naturally convects the control device unit from the lower surface air intake port of the front lower surface of the control device unit to the control device unit exhaust port of the rear upper part.

Further, the upper front air intake between the system kitchen and the main body and the lower front air intake at the lower front of the main body are common air intakes for forced cooling of the grill and cooling by natural convection of the controller. Acts as a mouth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is an external perspective view of an electric cooking heater according to an embodiment of the present invention, and FIG. 2 is a configuration diagram of the inside thereof.

In the figure, a main body 2 of a cooking heater is installed in a system kitchen 1, and three heating portions 3, 4, 5 are provided on the upper surface of the main body 2. Also the main body 2
A grill portion 6 for grilling fish is provided on the left side of the front of the device, and an operating portion 7 of a control device (described later) is provided on the right side. Reference numeral 8 denotes an exhaust cover provided on the rear side of the heating units 3, 4, and 5, which internally has a grill exhaust port 9 of the grill unit 6 and a cooling fan exhaust port 1.
0 and the control unit exhaust port 11.

Reference numeral 12 is a front air intake port and 13 is a front air intake port, which are provided on the upper surface or the lower surface of the main body 2, respectively. The main body 2 is provided with a grill portion 6 on the left side thereof, a heating device 3, 4, 5 on the right side thereof, and a control device portion 14 for controlling energization of the grill portion 6 via a partition plate 15.

The rear portion of the grill portion 6 is connected to the grill exhaust port 9, the grill portion 6 is covered with a wind tunnel 16, and a cooling fan 17 is provided behind the grill portion 6 to cool the cooling fan 17. It is connected to the fan exhaust port 10. Further, the control device section 14 has a lower surface air intake port 18 on the front lower surface thereof, and the rear side thereof is connected to the control device section exhaust port 11.

Next, the operation of this embodiment will be described.

The hot air generated from the inside of the grill portion 6 which is heated to sufficiently heat the inside of fish or the like is exhausted from the grill exhaust port 9, and the hot air generated from the outer periphery thereof passes through the wind tunnel 16 of the cooling fan 17. Cooling fan exhaust port 10 by action
It is forcibly exhausted from. At this time, the wind tunnel 16 prevents heat radiation from the grill portion 6, and the partition plate 15 prevents hot air from the grill portion 6 from flowing into the control device portion 14.

The control unit 14 includes a lower surface air intake port 18
The air that has been cooled and warmed by the inflow of air is discharged from the control unit exhaust port 11 by natural convection.
Further, the upper front air intake port 12 and the lower front air intake port 13 are for the forced cooling of the grill portion 6 and the control device portion 14.
Acts as a common air intake for cooling by natural convection.

Therefore, without using extra parts such as the heat insulating material and its mounting parts, the hot air generated most from the grill part 6 is smoothly discharged, and the control device part 14 is used.
Has almost no effect on. Further, since all the hot air is exhausted from the exhaust cover 8, it does not affect the surrounding system kitchen 1.

[0016]

As described above, according to the present invention, a partition plate for shutting off the grill part and the control device part is provided inside the main body, and a cooling fan for releasing hot air of the grill part divided by the partition plate is provided at the rear of the grill part. A wind tunnel is installed to cover the grill,
Similarly, a lower surface air intake for cooling the control device section divided by a partition plate is provided on the front lower surface of the control device section, and a control device section exhaust port is provided on the rear upper part of the control device section. Since the common front air intake is provided between the two and the lower front air intake is provided at the lower front of the main body, heat is prevented from radiating to the outer periphery of the grill that is hot in the wind tunnel, and the grill is cooled by the cooling fan. Efficiently forcibly discharge the exhaust heat of the control unit, the partition plate prevents the heat of the grill from flowing into the control unit, and the control unit can be cooled by natural convection, with a small number of parts and a simple and simple structure. A cheap, built-in type electric cooking heater can be provided.
