Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to heating cookers such as induction heating cookers and electric ranges used in kitchens, etc., and particularly relates to intake and exhaust devices thereof.

2. Description of the Related Art A conventional heating cooker equipped with this type of intake/exhaust device is
The structure is as shown in the figure.

That is, an intake/exhaust cover 4 with adjacent intake holes 2 and exhaust holes 3 disposed in the same plane is provided on the upper rear surface of the cooking device main body 1 having a heat source.

Below the intake hole 2 and the discharge hole 3 of the intake/exhaust cover 4, an intake passage 6 and an exhaust passage 6 are provided in the heating cooking device main body 1, respectively.

Problems to be Solved by the Invention However, in the conventional configuration, a portion of the heated exhaust gas discharged from the exhaust hole 3 is sucked into the cooking device main body 1 through the adjacent intake hole 2. Therefore, for example, when this intake air is needed to cool the electronic components inside the heating cooker main body 1, the intake air cannot draw in sufficient cold air from the outside unless it sucks in the heated exhaust gas. As a result, the cooling effect of electronic components deteriorates. In other words, in order to obtain an appropriate cooling effect,
There is a problem in that the intake hole and the exhaust hole of the intake/exhaust cover must be made wider than necessary. Also,
There was a problem in that it was impossible to separate the intake hole and the exhaust hole in order to make the product more compact.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to improve the cooling effect within the cooking device by making it difficult for the exhaust air from the exhaust hole to be sucked in through the intake hole even when the product is compact.

Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
The positions of the intake and exhaust holes provided in the upper part of the main body are different, and the intake holes are provided on a surface different from the surface on which the exhaust holes are provided.

For production The effect of this technical means is as follows.

That is, since the intake hole is provided on a different surface from the exhaust hole, the exhaust air from the exhaust hole is less likely to be sucked into the cooking device through the intake hole again, and a large amount of external cold air can be sucked in.

As a result, electronic components during cooking can be cooled more effectively than before.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2.

In FIG. 1, reference numeral 1 denotes a heating cooking device main body, and at the rear of the heating cooking device main body 1 are an air intake passage 2 and an exhaust passage 3 whose upper surface is open.
are located adjacent to each other. A substantially triangular intake/exhaust cover 4 is placed over the upper openings of the intake passage 2 and the exhaust passage 3. The intake and exhaust cover 4 also includes the intake passage 2 and the exhaust passage 3.
An intake hole 5 and an exhaust hole 6 are provided facing each other. Here, the intake hole 5 has an intake and exhaust force, and the rear slope of the bar 4 has
Further, the discharge hole 6 is provided on the upper front surface of the intake/exhaust cover. The lower end surface of the intake passage 2 is open and communicates with the outside of the cooking device main body 1, and the lower end surface of the discharge path 3 is open and communicating with the inside of the cooking device main body 1.

Reference numerals 7 and 8 denote a fan and electronic components respectively provided within the cooking device main body 1.

Next, the operation of the configuration of this embodiment will be explained.

While the cooking device is heating, cold air A is sucked in by the fan 7 in the cooking device main body 1 through the intake hole 5 of the intake/exhaust cover 4 according to the arrows in FIG.

Thereafter, the cold air A cools the electronic components 8 and the like within the main body 1 and is exhausted to the outside through the exhaust path 3 and the exhaust hole 6. Therefore, the exhaust air is considerably warmed air for cooling. However, even if the intake hole 5 and the exhaust hole 6 are adjacent to each other,
Since the intake holes 6 are provided on a surface different from the surface on which the exhaust holes θ are provided, the exhaust gas heated for cooling the electronic components 8 is difficult to be sucked into the six intake holes again. Therefore, the intake hole 6
The outside cold air sucked in from the outside is not heated.

In this embodiment, the intake/exhaust cover 4 is formed into a substantially isosceles triangular shape and the intake hole 6 is provided on the rear slope, but as shown in FIG. Similar effects can be obtained by providing the holes 5 on the rear vertical surface, or by providing the intake holes 5 on the side surface of the intake/exhaust cover 4 as shown in FIG.

Further, in this embodiment, the intake hole 6 is provided only on the rear surface of the intake/exhaust cover 4, but almost the same effect can be obtained by adding the intake hole 6a to the front slope where the exhaust hole 6 is provided, as shown in FIG. is obtained. This is because, like the exhaust hole 6, some of the exhaust air from the adjacent exhaust hole 6 is taken in through the intake hole 6a provided on the front slope, but cold air is sucked through the intake hole 6 provided on the rear surface of the intake/exhaust cover 4. be done. Therefore, the temperature of the intake air is considerably lower than that of the conventional example. Therefore, the electronic components inside the heating cooker can be efficiently cooled.

In the above embodiment, the exhaust hole 6 of the intake/exhaust cover 4 was used to exhaust the exhaust gas inside the cooking device, but the exhaust hole 6
The same effect can be obtained even if this is used in a heating cooker equipped with a bottom evacuation device as shown in FIG. That is, the discharge hole 6
A lower evacuation device 1o having a built-in fan 9 and a motor 1o is installed in the lower exhaust path 3 of the device, and the lower evacuation device 10 removes oil smoke etc. from the cooking utensils 11 during cooking.
The smoke is sucked downward through the exhaust hole 6 and exhausted to the outside.

At this time, since the intake hole 5 is provided on the rear surface of the intake/exhaust cover 4, it is difficult for oil smoke to be sucked through the intake hole 5. Therefore, it is possible to prevent the cold air sucked from the intake hole from being heated by the oil smoke.

Effects of the Invention As is clear from the description of the embodiments, in the present invention, the intake hole and the exhaust hole are provided on different surfaces, so that the exhaust air heated by cooling the electronic components in the cooking device can be heated. , it becomes difficult to be sucked into the intake hole again, and more cold air can be sucked in from the outside. Therefore, the electronic components can be effectively cooled, and as a result, the area of the air intake hole can be minimized, making it possible to reduce the size of the product.
