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 mechanism thereof.

Structure of the conventional example and its problems In the conventional induction heating regulator, as shown in Fig. 1, a cooling fan 2 is provided at a suitable corner inside the container body 1, and an intake port 3 is provided near the cooling fan 2. , an exhaust port 6 of uniform diameter 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, and B and C
It becomes difficult to flow in this order. For this reason, there was a drawback that the ventilation inside the container body 1 became non-uniform, and some parts were difficult to be cooled.

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, the It equalizes the ventilation inside and provides thorough cooling.

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

In FIGS. 2 and 3, reference numeral 11 denotes a substantially rectangular container, and a cooling fan 1 that rotates horizontally is installed in one corner of the container 11.
2 is provided. 13 is a motor for driving the cooling NOANO 12. 14 id is a heating coil provided in the container body 11; 16 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 designates 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 form 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 larger than the opening area of the exhaust ports 17b located close to the cooling fan 12. It is getting bigger and has 17 exhaust ports! The opening area of the exhaust port between L and the exhaust hole 17b gradually becomes smaller from the exhaust port 17a toward 17b.

In the above configuration, although the ventilation route A from the intake port 16 to the exhaust port 17b is short, the ventilation resistance is large because the opening area of the exhaust port 17b is small.
Although the ventilation route C from the intake port 16 to the exhaust port 1] 17a has a long distance, the ventilation resistance is small because the opening area of the exhaust port 17& is large, and as a result, the ventilation inside the container body 11 is improved. It is possible to uniformly cool the various electronic components of the container body 11 substantially uniformly.

In the above embodiment, a case has been described in which the exhaust port 17 is provided on the side wall 18 of the container body facing the corner where the cooling fan 12 is provided, but FIG.

As shown in FIG. 6, it may be formed continuously over the container side wall 18 facing the corner where the cooling fan 12 is provided and the bottom wall of the container 11 which is continuous with the container side wall 18. Also, as shown in FIGS. 6 and 7, the cooling fan 1
The exhaust port 17 may be formed in the bottom wall of the container body 11 at a position close to the container side wall 18 opposite to the corner where the exhaust port 2 is provided.

In any of the embodiments, the opening area of the exhaust port 17a located at a diagonal position of the cooling fan 120 is larger than the opening area of the exhaust port 17b near the cooling fan 12. The ventilation resistance of each exhaust route from the to the exhaust ports 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 description, according to the present invention, the air permeability of each exhaust path within the container can be made uniform, and the inside of the container can be thoroughly cooled.
