DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking device such as a cooking unit with a cabinet or a range unit with an oven, and is particularly applicable to a cartridge type cooking device in which a cooking device can be attached and detached as needed. be.

Conventionally, in the above-mentioned fields, when a cooker that requires ventilation to cool the heat generated by the internal device, such as an induction cooker, is used by being housed in the support body of the cooker unit, It is necessary to provide ventilation holes or a dedicated ventilation duct on the side of the support body, which has the disadvantage of complicating the structure.

The present invention solves the above-mentioned drawbacks,
By constructing a necessary ventilation path for the cooker when the cooker is inserted into a recess provided in the upper surface of a support body of a cooker unit or the like to removably house the cooker, This eliminates the need to provide a dedicated ventilation hole or dedicated ventilation duct on the support body side, resulting in an extremely simple configuration and high economic efficiency when using a cooking device such as an induction heating cooker in a cartridge system. This is what we provide.

The present invention provides a recess formed on the upper surface of a support body of a range unit with oven, etc., a box-shaped cooking device main body that is detachably inserted into the recess at a distance, and a peripheral edge of the cooking device main body. a support frame disposed between the periphery of the cooking device and the peripheral edge of the recess and supporting the cooking device main body; a first ventilation hole and a second ventilation hole formed in the frame; and a support frame that supports the cooking device main body; a fan for ventilating the inside and outside of the cooking device main body, the space formed between the cooking device main body and the recess and the first ventilation hole can be freely ventilated; By making ventilation holes and the internal space of the cooking device main body freely ventilated, hot air generated inside the cooking device main body can be effectively ventilated. When the fan operates, low-temperature outside air is drawn into the space from the first ventilation hole, enters the internal space of the cooking device main body from this space, and cools the heat-generating components inside the cooking device main body. The hot air is then exhausted from the second ventilation hole. Furthermore, it is also possible to take in air through the second ventilation hole and exhaust it through the first ventilation hole by reversing the blowing direction of the fan.

FIGS. 1 and 2 are external perspective views of an embodiment of the present invention. FIG. 1 shows an embodiment in which a cartridge type cooker is detachably housed on the top surface of a microwave oven unit.

There is. In FIG. 1, the cooking device 3a is shown inserted into the recess 2a, and the cooking device 3b is shown inserted into the recess 2b.
Indicates the state removed from. A user who owns several types of cartridge type cookers, such as a grill cooker and a radiant heater type cooker, can cook by inserting the cooker to be used into the recess 2a or 2b as necessary.

FIG. 2 is an external perspective view of the induction heating cooker inserted into the recess 2a, and shows the top plate 4.
A first ventilation hole 6 and second ventilation holes 7 and 8 are provided in the support frame 5 provided at the peripheral edge of the support frame 5 .
The arrows indicated by dotted lines indicate the direction of ventilation, and in FIG. 2, air is taken in from the first ventilation hole 6,
The air is exhausted from the second ventilation holes 7 and 8.

FIG. 3 is a cross-sectional view of the embodiment of FIG. 2; In the figure, the main body of the induction heating cooker is composed of a casing consisting of the top plate 4, the support frame 5, and the main body case 11, a ventilation fan 10, a high-frequency power supply 13, and a heating coil 12. The induction heating cooker is removably housed in a recess 2 formed in the upper surface of the support frame 1 of the microwave oven unit.

Further, the support frame 5 has a first ventilation hole 6 and
A second ventilation hole 7 is provided, and the second ventilation hole 7
is connected to the main body internal space 15 for free ventilation, and the first ventilation hole 6 is connected to the main body case 11 and the support frame 5.
The cooking device body external space 14 surrounded by the recess 2 of the support frame 1 is provided to allow ventilation. Further, a ventilation hole 9 is provided in the bottom of the main body case 11, and a fan 10 is disposed inside thereof facing the ventilation hole 9, and a fan 10 is arranged inside the main body case 11 to provide space between the main body internal space 15 and the main body external space 14. Provide ventilation. Here, when the fan 10 operates to blow air from the main body external space 14 to the main body internal space 15, the ventilation path of the entire device is the path shown by the dotted arrow, that is, the first ventilation hole 6.
The outside air taken in from the main body external space 14 passes through the ventilation hole 9 to reach the internal space 15, and is exhausted from the second ventilation hole 7. Furthermore, by reversing the operation of the ventilation fan, a reverse ventilation path can be formed in which air is taken in through the second ventilation hole 7 and exhausted through the first ventilation hole 6.

In this way, when the cooking device main body is stored in the container-shaped recess 2 during use, the space 14 formed between the main body case 11 and the container-shaped recess 2 acts as a ventilation guide path, Main body case 11
By acting as a partition plate that separates the intake side space and the exhaust side space of the ventilation fan 10, the outside air taken in from the top side of the main body can be exhausted to the top side of the main body. There is no need to provide a dedicated ventilation duct for this purpose. Therefore, the heat loss generated during operation of the high frequency power supply device 13 and the heating coil 12 provided in the induction heating cooker main body is effectively exhausted by the above-mentioned ventilation action, ensuring normal operation of the induction heating cooker. It is something.

FIG. 4 shows another embodiment of the invention. In FIG. 4, on the bottom side of the support body recess 2 on the outside of the ventilation fan 10, there is a conical ventilation guide body that is close to the center of the center fan 10 and has a taper such that its peripheral edge moves away from the peripheral edge of the fan 10. 16 is provided to reduce the blowing loss of the fan 10 and increase the blowing efficiency. That is, the ventilation guide plate 16 has a rectifying effect, and when ventilation is performed in the direction of the dotted arrow in the figure, if the ventilation fan 10 is an axial flow fan, if the ventilation guide plate 16 is not provided, the concave The fluid impinges on the bottom surface of the second part in the vertical direction, and the air loss in this part becomes very large. However, by providing the tapered ventilation guide 16, the fluid collision is alleviated, so that the airflow is rectified and the ventilation efficiency can be greatly improved.

As described above, according to the present invention, by configuring the space formed by the recess provided in the top surface of the support body of the range unit, cabinet, etc. and the cooker body case as a ventilation guide path, (1) the cooker body Even though the support body is drop-in stored in the support body, there is no need to provide ventilation holes or ducts on the support body side, and the overall ventilation configuration is extremely simplified.

(2) Furthermore, since there is no need to provide an independent ventilation guide path to the ventilation hole on the top side of the cooking device on the side of the cooking device, the structure of the cooking device is simplified.

(3) In order to carry out air intake and exhaust around the top surface of the cooking device, it is also possible to configure the top surface of the cooking device and the top surface of the support main body to be almost on the same plane by providing an appropriate waterproof device in the 7 ventilation holes. Despite being removable, the design and usability are almost the same as conventional fixed storage cookers.

(4) By forming the external space of the cooker body into a duct shape, it gives a rectifying effect to the airflow and enables efficient ventilation with little fluid loss. Furthermore, by providing a ventilation guide, ventilation efficiency can be further improved.
