Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cooking device provided with an induction heater, and more particularly, to a cooling means for a built-in heat generating component or the like.
[0002]
[Prior art]
Conventionally, this kind of cooking device is provided in the main body case by sucking outside air from a suction port provided on the upper surface of the main body case behind the top plate as disclosed in, for example, JP-A-2001-267054. The board or the like on which the heat generating component is mounted is cooled and exhausted from an exhaust port provided on the upper surface of the main body case, thereby preventing a temperature rise in the main body case.
[0003]
[Problems to be solved by the invention]
In the conventional heating cooker as described above, since the outside air intake port is provided on the upper surface of the main body case, oil mist such as steam and tempura generated during cooking is sucked and the inside of the main body case becomes odorous. In addition to this, there is a risk that oil mist adheres to electrical parts, fans, etc., and deteriorates or functions deteriorate.
Further, since the intake and exhaust ports are provided on the upper surface, the upper surface of the main body case cannot be used widely.
[0004]
The present invention has been made in order to solve the above-mentioned problems, and without changing the structure and dimensions of the main body case, the outside air suction port is provided at a position where there is no possibility of sucking in steam or oil mist. It is an object of the present invention to provide a cooking device that can effectively use the upper surface of the wide area.
[0005]

[0018]
Next, the operation of the cooking device according to the present invention will be described with reference to FIGS.
When cooking, a cooking pan or the like is placed on part or all of the circle lines 13, 14, 15 on the induction heater 33 provided on the top plate 12, and the operation unit 71 is operated to operate in the lower unit 4. The power supply circuit 41 is energized. The drive control circuit 34 in the upper unit 3 is driven by the output of the power supply circuit 41 to energize the induction heater 33, and at the same time, the thermal power display lamp 16a is turned on.
As a result, the power semiconductor 36 of the drive control circuit 34, the transformer 43 and choke coil 44 of the power supply circuit 41, the electromagnetic interference prevention coil 46, etc. generate heat.
[0019]
Simultaneously with the energization of the induction heater 33, the motor 53 of the blower unit 5 is energized and the fan 54 is rotationally driven. As a result, outside air is drawn from the intake hole 82 of the side cover 8, is sucked into the blower unit 5 from the outside air intake port 19 through the intake passage 91, and is sucked out from the blowout port 52 to radiate heat from the power semiconductor 36 of the drive control circuit 34. The plate 37 is cooled and discharged to the outside through a gap 92 formed between the front panel 7 and the kitchen cabinet 9 through the exhaust port 32 of the front plate 31.
[0020]
Further, a part of the air blown out from the blowout port 52 flows from the opening 23 of the external airflow inlet 22 and flows into the lower unit 4 from the blowout port 24, and the transformer 43, choke coil 44, and semiconductor of the power circuit 41.

At this time, the flue gas cylinder 65 is installed obliquely upward from the flue gas outlet 64 toward the flue gas outlet 18, and its length is short so that the flow of the flue gas is good. 6 does not stay. Further, even if oil or the like adheres on the way, it is inclined so that it flows down and returns to the fish grilling chamber 6, so that oil does not accumulate in the smoke exhausting cylinder 65.
Further, the deodorization filter 66 is provided in the flue gas outflow portion 64 so that the flue gas is decomposed into water vapor and carbon dioxide gas, so that the odor of the flue gas discharged from the flue gas outlet 18 can be greatly reduced. .
[0022]
In the present invention, when the side cover 8 having the air intake holes 82 is attached to both front sides of the main body case 1 and the main body case 1 is set in the kitchen cabinet 9, the side wall and the rear wall of the main body case 1 and the kitchen cabinet 9 Since the front side of the gap (intake passage 91) formed between the inner peripheral wall and the intake wall 91 is closed, the outside air is taken into the blower unit 5 through the intake passage 91 of the side cover 8. The heat generating part can always be cooled by clean air without changing the dimensions and structure of the main body case.
Further, it is not necessary to provide an outside air inlet on the upper surface of the main body case 1 and only a smoke exhaust outlet 18 for exhausting the exhaust from the fish grilling chamber 6 is provided, so that the upper surface can be used widely and effectively. it can.
[0023]
In the above description, the case where the side covers according to the present invention are attached to the left and right of the front side of the illustrated cooking device is shown, but the present invention is not limited to this, and the heating cooking device having another structure is also implemented. be able to.
[0024]
【The invention's effect】
The cooking device according to the present invention has a top plate on the upper surface, one or a plurality of induction heaters disposed on the lower surface side of the top plate, a drive control circuit for driving the induction heater, and drive control. When there is a heating cooker with a main unit case with a built-in fan unit for cooling circuits, etc., and a fish grilling box with an operation part on the front side, and this heating cooker is set in a kitchen cabinet In addition, the front side opening of the air intake passage formed between the side wall and the rear wall of the main body case of the heating cooker and the inner peripheral wall of the kitchen cabinet is closed with a side cover having an air intake hole. Since the outside air taken in from the intake hole is reliably taken into the main body case through the intake passage , the heat generating portion can be always cooled with clean air.
[0026]
Moreover, since only the smoke exhaust outlet which discharges | emits the smoke of a fish grill is provided in the upper surface of the main body case of said heating cooker, the upper surface can be used widely widely.
