Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating cooker such as an induction heating cooker, and particularly to a cooling structure thereof.

Conventional structure and its problems Traditionally, induction heating cookers have an air intake in the corner of the housing, a cooling fan placed close to the air intake, and an exhaust port formed on the side wall of the housing opposite the air intake. and a heating coil provided in the center of the housing. In this induction heating cooker, as shown in FIG. Since the flow is strong along the line L, parts located off the diagonal line L are not cooled well. However, when considering the arrangement of components within the housing, the heating coil 5 placed approximately in the center of the housing 4
Since the dimension between and the bottom surface of the housing is smaller than other locations, and it is easy to receive radiant heat from the heating coil 5, components are placed along the side wall of the housing 4 around the heating coil 5. becomes relatively large.
However, as described above, there is a drawback in that parts located outside the diagonal line L of the housing 4 are not cooled well.

OBJECTS OF THE INVENTION The present invention eliminates the above-mentioned conventional drawbacks, and aims to effectively cool components disposed near the side walls of the housing.

Structure of the Invention In order to achieve the above object, the heating cooker of the present invention includes a cooling fan provided at one corner of a housing, a heating source placed approximately in the center of the housing, and a side wall or the like facing the one corner. An exhaust port formed nearby and arranged near the cooling fan divide the cooling air into two,
The housing is provided with a flow regulator that allows ventilation to flow along each side wall of the housing located at one corner.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the drawings.

In FIG. 2, 6 is a housing, and this housing 6
An intake port 7 is formed at the corner of the bottom surface. 8 is a cooling fan provided in one corner of the housing 6 above the intake port 7. An exhaust port 10 is formed in a side wall 9 facing one corner of the housing 6 in which the cooling fan 8 is provided. 11 is a heating coil provided in the center of the housing 6.

Also, along the two side walls 18 and 19 of the housing 6 close to the cooling fan 8, a heating coil 11, a heat radiation fin 13 used for cooling the starting transistor 12, and a diode bridge rectifier 14 are installed in different directions. A heat radiation fin 15 used for cooling is provided. Since the heat dissipation fins 13 and 15 are comb-shaped as shown in FIG. 3, even if the cooling air sent out by the cooling fan 8 is distributed in different directions, the heat dissipation fins 13 and 15 can greatly cool the cooling air. Air is distributed in two directions along two side walls 18 and 19 of the housing 6 close to the fan 8.

The operation of the above configuration will be explained below.
The cooling air distributed in two directions by the heat dissipation fins 13 and 15 leads to the exhaust port 10, as shown by the arrows in the figure. As shown in B, the air collides once with the side wall surface 16 of the housing 6, but takes a bending path toward the exhaust port 10. As a result, most of the cooling air flows along the side wall of the casing 6, and less cooling air flows through the heating coil 11, which has a high heat-resistant temperature, and the lower part of the heating coil, which has fewer parts. , i.e. the periphery of the housing 6
Components located along the side walls of the vehicle will be strongly cooled.

As described above, according to this embodiment, the cooling air is distributed in two directions along the side wall of the casing located at one corner where the cooling fan is arranged, so that the cooling air is distributed in two directions along the side wall of the casing where components are easily placed. Two streams of cooling air are distributed throughout, and components placed on this ventilation path are cooled well.

FIG. 4 shows another embodiment of the present invention, in which the flow is regulated by a wall member 17 provided in an arc shape near the cooling fan 8 and around the intake port 7 at the center of the housing. It is configured. In this way, the cooling air blown from the cooling fan 8 will be directed to arrows A and B in the figure.
Most of it flows in the direction of , and the same effect as in the previous embodiment can be obtained. Note that the wall-like member 17 forming a flow regulator
As shown in FIG. 5, it is preferable that the cooling fan 8 be provided at least at a higher position than the cooling fan 8.

Effects of the Invention As described above, according to this embodiment, the cooling air is distributed in two directions along the side wall of the housing located in one corner where the cooling fan is arranged. Components arranged side by side can be efficiently cooled by the two cooling airflows, and the number of components that can be arranged along the side wall can be increased to significantly reduce the number of components that are affected by radiant heat from the heating source.
