Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heating cooking device having a mechanism for cooling the inside of the main body.

2. Description of the Related Art An induction heating device, which is an example of a conventional heating device, is shown in FIGS. That is, four heating coils 2, 3° 4.6 are arranged below the top plate 1, and intake ports 6, 7 are arranged at both ends of the rear upper surface of the main body. An exhaust port 8 is arranged inside these intake ports 6 and 7. Two cooling fans 9 are arranged inside the main body. The heating coils 2, 3 and cooling fan 9 on the left side are integrated into a unit, and the sixth
As shown in the figure, when the cooling fan 9 rotates, air is sucked into the main body from the intake port 6 on the rear left side of the main body, passes through the exhaust duct 1o at the bottom of the cooling fan 9, and is exhausted from the exhaust port 8. In addition, the heating coil 4.6 on the right side and the cooling fan on one side are also unitized in the same way, and when the cooling fan 9 rotates, air is sucked into the main body from the intake lower on the right side, and is exhausted from the exhaust port 8 through the exhaust duct 10. was.

However, with such a conventional configuration, the intake port 6.7
Since the air sucked in from the intake port 6 directly enters the inside of the main body,
．． There has been a problem in that dirt sucked in from the main body, oil smoke generated during cooking, etc. are easily sucked into the main body, making the inside of the main body dirty and, when attached to live parts, easily causing a leak.

In particular, since the left intake port 6 is located near the left rear heating coil 2, it is easy to inhale oily smoke when cooking using the left rear heating coil 2.

Therefore, an object of the present invention is to make it difficult for dust and oil smoke to enter the inside of the main body even if the dust or smoke is sucked in through the intake port.

Means for Solving the Problems and In order to solve the above problems, the heating device of the present invention has the following features:
An air intake port is provided on the upper surface of the main body having a heating source, a ventilation passage connected to the air intake port is guided into an installation stand on which the main body is installed, and a fan inlet is provided on the outer surface of the main body located within the installation stand. The configuration is as follows.

Function: According to this configuration, the cooling air sucked in from the air intake port is not guided directly into the main body, but enters the space inside the installation base on which the main body is installed from the air intake port via the ventilation path, The air is sucked into the main body from the space inside the stand through the fan suction port on the outside of the main body. Therefore, when dirt or oil smoke is sucked in from the suction port, it falls to the floor as it passes through the space inside the installation stand, making it difficult to suck it into the main unit, and dirt inside the main unit may cause the dirt. It is possible to prevent leaks that would otherwise occur.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIGS. 1 and 2, the four heating coils 21, 22, 23, and 24, which are the heating sources, are arranged so as to be located on an inclined line with respect to the adjacent heating coils.

An intake port 26 is arranged at the right rear portion of the main body 26. Also,
A duct-shaped ventilation passage 28 having an opening 27 at the bottom is provided below the intake port 2e. Furthermore, the main body 26
A fan inlet 31, which is an intake port for the cooling fan 3°, is arranged below the top plate 29 of the installation stand on which the equipment is installed, that is, on the lower surface of the main body 26 located inside the installation stand.

In such a configuration, the air flow for cooling the inside of the main body 26 is directed through the air intake port 26 as shown by the arrow in FIG.
It passes through the ventilation path 28 below, enters the space 32 between the main body 26 and the installation stand 29, and from this space passes through the fan suction port 31 on the bottom surface of the housing, and enters the inside of the main body 26 by the cooling fan 30. be guided. Here, if dust or oily smoke generated during cooking is sucked in through the intake port 28, the dust or oily smoke passes through the ventilation path 28 and enters the space 32 between the main body 26 and the installation stand 29. Since the space 32 between the main body 26 and the installation base 29 is sufficiently wider than the ventilation passage 28, the wind speed in this space 32 is sufficiently lower than the wind speed in the ventilation passage 28.

Therefore, the garbage and oil smoke that have been guided to this space 32 tend to fall to the floor surface 33 due to their own weight. Furthermore, since the wind speed is slow, it is possible to suppress dust and oil smoke that easily falls to the floor and is sucked into the main body 26 from the fan suction port 31.
It is possible to prevent dirt inside the main body 26 and leaks that occur when this dirt occurs in the charging part.

In addition, in this embodiment, the intake port 2e is connected to four heating coils 2.
1.22.23.24, it is placed at the rear of the top surface of the main body opposite to the heating coil 24 on the right side located at the front of the main body, so the distance from the heating coil 24 can be increased, so the suction port 26 can absorb oil smoke. The cooling effect can be improved since the amount of heat can be reduced and hot air is difficult to inhale.

Note that although this example shows the case of an induction heating cooker,
The present invention is not limited to this, but can be applied to a heating cooking device that has a heating source in the main body and needs to cool the inside of the main body.

Next, a second embodiment of the present invention will be described.

FIG. 3 shows a second embodiment, in which the heating coil 41.
42, 43, and 44 are arranged in a substantially trapezoidal shape, and the left front heating coil 41 and the adjacent rear heating coil 42 and the right front heating coil 44 and the adjacent rear heating coil 43 are respectively on the plane slope line. It is arranged in A first intake port 46 is provided at the rear left end of the upper surface of the main body 26 in a portion facing the left front heating coil 41, and a second intake port 46 is provided in a portion facing the right front heating coil 44 at the rear right end of the upper surface of the main body 26. Mouth 4
6 is placed. In this embodiment as well, the first intake port 46 directs oil smoke and hot air generated in the left front heating coil 41 portion, and the second intake port 46 directs oil smoke and hot air generated in the right front heating coil 44 portion into the main body. It becomes difficult to inhale, and the same effect as in the above embodiment can be obtained.

Further, a third embodiment will be described.

FIG. 4 shows a third embodiment, in which the two heating coils 51 and 52 are arranged such that the right heating coil 62 is placed in front of the left heating coil 51.
．． 52 is arranged on a plane slope line. In addition, the main body 26
An air intake port 63 for cooling the inside is arranged on the rear right side of the upper surface of the main body 26, and is located behind the heating coil 62 on the right side. In this embodiment as well, the air inlet is placed in a position where it is difficult to suck in the oily smoke generated by the heating coils 51, 62, and the same effects as in the previous embodiment can be obtained.

Effects of the Invention As is clear from the above embodiments, according to the present invention, a ventilation passage connected to the intake port on the top surface of the main body is guided inside the installation base,
Since the air that needs to be cooled is sucked into the main unit from the fan intake port, dirt and oil smoke sucked in from the air intake port are sucked into the main unit, and the inside of the main unit gets dirty, and this dirt gets onto the live parts of internal parts. This can prevent leaks from occurring.
