Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking device such as an induction heating cooking device, and particularly to a cooling structure thereof.

Structure of conventional example and its problems As shown in FIG. , an exhaust port 5 of uniform size was provided on the side wall 4 of the container body facing the cooling fan 2. Possible ventilation paths within the container 1 from the intake port 3 to the exhaust port 5 are A, B, C, etc. as shown by arrows. Route A has the shortest distance, so it flows easily.
It becomes difficult to flow in the order of B and C. For this reason, the ventilation inside the vessel 1 becomes uneven, resulting in the disadvantage that some parts are difficult to cool.

OBJECTS OF THE INVENTION The present invention aims to eliminate the above-mentioned conventional drawbacks, and aims to equalize the ventilation inside the container and cool the entire inside of the container.

Structure of the Invention In order to achieve the above object, the cooking appliance of the present invention is provided with a cooling fan that rotates horizontally in one corner of a substantially rectangular container body, and a side wall of the container opposite to the corner where the cooling fan is provided, or By forming multiple vents close to the side wall of the vessel, and making the opening area of the vents located diagonally to the cooling fan larger than the opening area of the vents located close to the cooling fan, It equalizes the ventilation inside and provides thorough cooling.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIGS. 2 and 3, reference numeral 11 denotes a substantially rectangular container, and a cooling fan 12 that rotates horizontally is provided at one corner of the container 11. 13 is a motor for driving the cooling fan 12. 14 is vessel 1
1 is a support plate that supports the heating coil 14; Reference numeral 16 denotes an air intake port formed on the bottom surface of the container body 11, facing the cooling fan 12. Reference numeral 17 denotes a plurality of exhaust ports formed in the side wall 18 of the container body facing the corner where the cooling fan 12 is provided. The plurality of exhaust ports 17 are formed in the shape of slits in the side wall 18 of the container, and the opening area of the exhaust ports 17a located diagonally to the cooling fan 12 is as follows:
The opening area of the exhaust port 17b located close to the cooling fan 12 is larger than that of the exhaust port 17b, and the opening area of the exhaust port between the exhaust port 17a and the exhaust port 17b gradually becomes smaller from the exhaust port 17a toward the exhaust port 17b.

In the above configuration, from the intake port 16 to the exhaust port 17
Although the ventilation route A leading to the point b has a short distance, the opening area of the exhaust port 17b is small, so the ventilation resistance is large, and the air flow from the intake port 16 to the exhaust port 17 is
Although the ventilation path C leading to point a has a long distance, the opening area of the exhaust port 17a is large, so the ventilation resistance is small, and as a result, the ventilation inside the container 11 is made uniform, and the Various electronic components can be cooled substantially uniformly.

In addition, in the above embodiment, the case where the exhaust port 17 is provided in the side wall 18 of the container body opposite to the corner where the cooling fan 12 is provided has been described.
As shown in FIG. 5, over the container side wall 18 facing the corner where the cooling fan 12 is provided and the bottom wall of the container 11 continuous with this container side wall 18,
Alternatively, as shown in FIG. 6 and FIG.
An exhaust port 17 may be formed in the bottom wall of 1.

In both embodiments, the opening area of the exhaust port 17a located at a diagonal position of the cooling fan 12 is larger than the opening area of the exhaust port 17b near the cooling fan 12.
The ventilation resistance of each exhaust route from 6 to each exhaust port 17 becomes uniform, and every corner of the container body 11 can be thoroughly cooled.

Effects of the Invention As is clear from the above explanation, according to the present invention, the air permeability of each exhaust route in the container is made uniform,
It is possible to cool the entire interior of the vessel.
