Heating components 19a-19e in the frame are cooled by the cooling wind obtained by two fans 11, 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an induction heating cooker,
Particularly, it relates to the cooling structure.

[0002]

2. Description of the Related Art A conventional induction heating cooker will be described below. In FIG. 4, reference numeral 1 denotes components 2a to 2 inside the housing 3.
An intake cooling fan for cooling e, 4 is an intake port provided at one corner of the housing 3, 5 is an exhaust port formed on the wall surface of the housing facing the intake port 4, and 6 is a heating coil.

Since the induction heating cooker configured as described above has many heat-generating components 2a to 2e therein, the cooling fan for intake 1 is used to cool the component to blow air into the interior. By continuing, the heat-generating components 2a to 2e were cooled and heat was released from the exhaust port 5.

[0004]

However, it is difficult to control the flow of air after intake to the exhaust port 5 with the above-mentioned conventional structure, and the intake cooling fan 1 from the intake port 4 located close to the intake port 4 is difficult to control. As the distance increases, the wind speed also suddenly weakens and the good cooling of the components 2a to 2e is not performed. Therefore, the fan speed is increased by increasing the fan shape or increasing the rotation speed of the motor to cool the heat generating components. There must be.

However, in the conventional structure, when the wind speed is increased by the above method, noise increases, which makes it difficult to reduce the size and thickness of the induction heating cooker. It was

The present invention solves the above-mentioned problems of the prior art by increasing the air volume passing through the inside of the housing without enlarging the shape of the fan or increasing the noise, thereby making it possible to intake air at the corners of the housing. The first purpose is to achieve good cooling even for parts away from the mouth, and to realize a smaller and thinner induction heating cooker. A second object is to cool the parts more efficiently.

[0007]

In order to achieve the first object, the induction heating cooker of the present invention comprises an intake port located at one corner of the housing, and an intake cooling fan adjacent to the intake port. An exhaust port provided at a housing position facing the intake port,
The induction heating cooker is provided with an exhaust cooling fan close to the exhaust port.

In order to achieve the second object, the induction heating cooker of the present invention is an induction heating cooker in which cooling fans for intake and exhaust are provided on diagonal lines of the housing.

[0009]

With the above structure, the intake air cooling fan and the exhaust air cooling fan work to make the air velocity distribution inside the housing almost uniform, so that the cooling air introduced from the air intake port into the housing is introduced into the air intake port. The wind speed will be maintained even after cooling the near heat generating parts, and the parts far from the intake port can be sufficiently cooled, which enables downsizing and thinning of the induction heating cooker. be able to.

Further, due to the arrangement of the intake and exhaust cooling fans, the cooling air can cool each component efficiently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the first invention will be described below with reference to the drawings. In FIG. 1 and FIG. 2, reference numeral 13 denotes a housing, an intake port 14 is formed on the lower surface of one corner of the housing 13, and an exhaust port 15 is formed on the wall surface of the housing 13 facing the intake port 14. Has been done. An intake cooling fan 11 and an exhaust cooling fan 12 are installed near the intake port 14 and the exhaust port 15, respectively. Further, 16 is a heating coil located substantially in the center of the housing 13, 17 is a cooking container such as a pot, 18 is a top plate on the top surface of the housing 13, and the cooking container 17 is placed on the upper surface and the heating coil is placed on the lower part. Equipped with 16. 19a to 19e is a case 1
These are various parts provided in 3.

The operation of the above structure will be described. The air sucked into the housing 13 from the intake port 14 by the cooling fan 11 for intake air is the components 19a to 19e in the housing 13.
Heading for the exhaust port 15 while taking away the heat of. At this time, the components near the intake cooling fan 11 are strongly cooled, but the temperature of this air rises because heat is taken from the components, and the wind speed weakens after colliding with the components. The cooling effect decreases. However, due to the operation of the exhaust cooling fan 12 near the exhaust port 15, the exhaust port 1
Since the cooled air approaching 5 is again accelerated and exhausted to the outside of the housing 13 through the exhaust port 15, even if the heat generation of each component is the same as in the conventional example, the shape of the cooling fan is not increased, The cooling effect in the housing 13 can be improved as compared with the conventional example. Therefore, the induction heating cooker can be made smaller and thinner.

An embodiment of the second invention will be described below with reference to the drawings. In FIG. 3, 21 is an intake cooling fan, 22 is an exhaust cooling fan, 23 is a housing, 2
4 is an intake port, 25 is an exhaust port, 26 is a heating coil, 27a
27e are various components provided in the housing 23. The above configuration is basically the same as the configuration of FIG. The difference from the configuration of FIG. 1 is that an exhaust cooling fan 22 and an exhaust port 2 are provided.
5 is arranged at a position of the housing 23 on a diagonal line between the intake cooling fan 21 and the intake port 24.

In the above structure, as shown in FIG. 3, an intake cooling fan 21 and an exhaust cooling fan 22 are provided in a housing 23.
Since the cooling air is distributed almost uniformly in the housing 23 by providing it on the diagonal line, the distribution of the wind speed in the housing 23 becomes almost uniform, and the components 27a to 27e do not depend on the arrangement. Since a good cooling effect can be obtained, it is possible to further reduce the size and thickness of the induction heating cooker.

[0015]

As described above, in the induction heating cooker of the present invention, the intake port located at one corner of the housing, the intake cooling fan adjacent to the intake port, and the housing facing the intake port. By providing an exhaust port provided at a position and an exhaust cooling fan close to this exhaust port, and cooling the components inside the housing using the two cooling fans, good cooling of the internal components can be achieved. It can be realized and the induction heating cooker can be made smaller and thinner.

By arranging the two cooling fans diagonally in the housing, the cooling effect of the parts inside the housing is increased, and the induction heating cooker can be made smaller and thinner. it can.
