Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite cooker in which a heating means for radiating infrared rays and an electromagnetic cooker are combined.

[0002]

2. Description of the Related Art A conventional composite cooking device will be described with reference to FIG. 2 in the figure
Is a heating unit for heating an object to be heated, and 3 is a roaster unit 3 for grilling fish. Reference numeral 4 denotes a control panel section, which is composed of an operating section for energizing the heating section 2 and the roaster section 3 and an operation for setting a heat quantity, and a display section for displaying the heat quantity of the heating section 2 and the like. The heating unit 2 is composed of a heating means 8 for radiating infrared rays, a heating coil 9 of an electromagnetic cooker, and a transparent top plate 10 arranged above the heating means 8 and the heating coil 9. An object to be heated is placed on the top plate 10 for cooking.

Reference numeral 11 is a main body case of the composite heating cooker, and 13 is a switching element mounted on a heat dissipation plate 14 provided in the main body case 11 for driving the heating coil 9, which becomes extremely hot. Therefore, the switching element 13 radiates heat through the heat radiating plate 14, and further cools the outside air by sucking the cool air of the outside air from the air suction port 16 provided in front of the bottom surface of the main body case 11 by the cooling fan 15 provided on the front side of the heat radiating plate 14. It is carried out. In addition, a small hole, a square hole, or a mesh-like net is attached to the air suction port 16 so that the rotating part of the cooling fan 15 cannot be directly touched by the hand.

[0004]

In the above-described conventional composite heating cooker, since the cooling fan 15 sucks dust and dirt together with the air, the air suction port 16 and the cooling fan 15 in the main body case 11 and the switching element. There is a problem that dust and dirt adhere to the heat sink 13, the heat sink 14, and the heating coil 9. In addition, since the combined heating cooker cannot be easily removed once it is installed in the system kitchen, when removing dust and dirt adhering to the air suction port 16 and the main body case 11, it takes a lot of time and effort to disassemble. It was a thing.

Further, if dust or dirt is left as it is without being removed, the cooling efficiency by the cooling fan 15 may be lowered, and in some cases, the switching element 13 may be destroyed.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, in which heating means for radiating infrared rays, a heating coil of an electromagnetic cooker, and a transparent top plate are arranged above the heating means. In a composite heating cooker including a heating unit for heating an object to be heated and a control circuit provided in the main body case for driving the heating unit, a heat generating component such as a switching element on the heating coil side in the main body case Equipped with a cooling fan to cool down the main body case, an air intake port is provided in the front of the bottom of the main unit case for sucking cooling air with a cooling fan, and a filter for removing dust and dirt is provided at this air intake port. The handle is attached so that it can be removed from the front, and the handle is connected to the filter so that it can be moved freely.

[0007]

With the above-described structure, the cooling fan sucks the cooling air from the air suction port to directly cool the heat-generating components such as switching elements and promotes the heat radiation from the heat-radiating plate for radiating the heat-generating components to reduce the temperature rise. Let Further, the filter provided in the narrow air suction port on the front side of the bottom surface of the main body case can be easily attached / detached by the handle to remove dust. Further, a handle which is connected to the filter by a rivet or the like and can be freely moved can usually be stored in the air suction port, and can be pulled out from the air suction port when taking out the filter.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view of a composite heating cooker to which an embodiment of the present invention is applied, FIG. 2 is a partially cutaway perspective view showing a component structure thereof, and FIG. 3 is a perspective view of an essential part thereof. is there.

In the figure, reference numeral 1 is a composite heating cooker incorporated in a system kitchen, which comprises a heating section 2 for heating an object to be heated and a roaster section 3 for grilling fish. Reference numeral 4 is a control panel section, which is an operation section 5 for energizing the heating section 2 and the roaster section 3 and for setting the heat quantity.
And a display unit 6 for displaying the amount of heat of the heating unit 2 and the like. The control panel unit 4 may be a retractable panel. 7 is a storage room of the system kitchen, and sometimes a microwave oven or an oven is incorporated in this part.

The heating section 2 includes heating means 8 for radiating infrared rays, a heating coil 9 for an electromagnetic cooker, and these heating means 8
And a transparent top plate 10 arranged above the heating coil 9, and an object to be heated is placed on the top plate 10 for cooking. 1
Reference numeral 1 denotes a main body case of the composite heating cooker 1, which has a control circuit 12 for driving the roaster unit 3, the operating unit 5, the heating means 8 and the heating coil 9.

Reference numeral 13 denotes a heat radiating plate 1 provided in the body case 11.
4 is a switching element mounted on 4 for driving the heating coil 9, 15 is a cooling fan provided on the front side of the heat radiating plate 14, and 16 is this cooling fan 1.
5 is an air suction port, which is provided in front of the bottom surface of the main body case 11 and sucks cold outside air. Reference numeral 17 denotes a filter attached to the air suction port 16, reference numeral 18 denotes a handle for pulling out the filter 17, and the handle 18 is movably attached to the filter 17 via a rivet 19. Reference numeral 20 denotes a guide rail for pulling out the filter 17, which is attached to the main body case 11, and the filter 17 is inserted between the guide rail 20 and the main body case 11. The handle 18 may be directly attached to the filter 17 as long as it can rotate.

An object to be heated is placed on the top plate 10,
When a cooking operation is performed by the operation unit 5, the amount of heat of the heating unit 2 is displayed on the display unit 6 according to the operation, and the heating means 8 and the heating coil 9 are energized to perform the cooking. At this time, the switching element 13 that drives the heating coil 9 becomes extremely hot,
The temperature rise is reduced by the cool air sucked from the outside air by the cooling fan 15 and the cooling from the heat dissipation plate 14 that radiates heat by the cooling fan 15. Further, when the cooling fan 15 sucks the cool air of the outside air, dust and dirt are sucked at the same time, but the dust and dirt are attached to the filter 17.

The filter 17 and its handle 18 are housed in a narrow air suction port 16 in front of the bottom surface of the main body case 11, and when the filter 17 is attached and detached, as shown in FIG. Dust and dust adhering to the filter 17 can be removed by pulling the knob forward as shown in the drawing, sliding the filter 17 on the guide rail 20 and pulling it forward as shown in the drawing.

[0015]

According to the present invention, in the composite heating cooker, since the cooling fan is provided in the main body case and the air suction port is provided in front of the bottom surface of the main body case, the heat generated by the switching element or the like on the heating coil side in the main body case is generated. The parts can be cooled sufficiently by the cooling air sucked in by the cooling fan, and it is possible to prevent the destruction of switching elements, etc., and a filter is installed in the narrow air suction port in the front of the bottom of the main unit case to attach a handle to this filter. treasure,
