At this time, by providing the guide plate 11a at the upper end of the guide plate 11, the cooling air of the high frequency generator 8 and the high pressure transformer 9 is prevented from flowing back into the stove 1 and the oven 3, and the exhaust area of the exhaust port 5 is ensured. It is divided into Furthermore, the partition plate 13 prevents hot air from the oven 3 from flowing to the stove 1 and the grill 2 (Japanese Patent Application No. 59-20242).

Problems to be Solved by the Invention However, according to the above-mentioned conventional configuration, out of the hot air discharged from the exhaust port 4, only the condenser 01. While the hot air from the grill 2 and oven 3 is by natural convection, the cooling fan 7
The hot air is forced convection, and compared to natural convection, the exhaust speed is
Since both the exhaust capacity is large, the hot air caused by the natural convection tends not to be sufficiently exhausted, resulting in the drawback that the hot air is trapped inside the device body and the temperature of each part increases. In order to solve this problem, extra parts such as heat insulating plates and partition plates to prevent heat and wind are required, which increases costs and increases the number of parts and assembly man-hours. .

The present invention solves the above-mentioned conventional problems, and aims to provide a composite heating cooker that can prevent temperature increases in various parts and improve safety within a limited space.

Means for Solving the Problems In order to solve the above problems, the composite heating cooker of the present invention includes a stove, a grill located below the stove, an oven located below the grill, A space between the high-frequency heating device, which serves both as an oven and a cooking compartment, and has electrical components such as a cooling fan arranged below the oven, the partition plate that partitions the grill and oven, and the rear wall plate of the main body of the device. between the partition plate and a first guide body forming a first ventilation passage through which cooling air that is forcibly taken in by the cooling fan and cools the high-frequency heating device flows into the first guide body;
a second guide body forming a second ventilation passage that communicates the ventilation passage with an opening formed on the entire surface of the device body;
A perforation formed in the second guide body, and a second guide member attached to the second guide body at a position near the perforation.
and a branch plate that guides a part of the cooling air in the ventilation passage to the grill side.

Effects According to the above configuration, since the cooling air that has cooled the high-frequency heating device is exhausted from the opening in the front of the device body, the area for exhausting hot air due to natural convection within the device body becomes large, and
Since the natural convection is smoothly exhausted without being disturbed, it is possible to prevent a rise in temperature in various parts within the main body of the device.

In addition, the branch plate allows a portion of the cooling air in the second ventilation path to be guided to the grill side through the perforations, so that functional parts such as the grill and stove cock and igniter can be cooled with the cooling air. A portion of the air is used as combustion air for the stove.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a schematic sectional view of a composite heating cooker according to an embodiment of the present invention, and the same components as those shown in FIGS. 2 to 4 are given the same reference numerals and their explanations are omitted. do. In FIG. 1, 15 is a first guide body, 16 is a second guide body, 17 is an opening, 18 is a perforation, and 9 is a branch plate. In this embodiment, the first guide body 15 and Rear wall board 12
and between the second guide body 16 and the partition plate 13, a ventilation path is formed that guides cooling air from the exhaust port 10 to the opening 17. Further, the branch plate 19 guides a portion of the cooling air in the ventilation path to the grille 2 side through the perforations 18.

According to the above configuration, the cold air taken in from the intake port 6 by the cooling fan 7 cools the electric components such as the high frequency generator 8 and the high frequency transformer 9, and then flows between the first guide body 15 and the rear wall plate 12. between the second guide body 16 and the partition plate 13
It reaches the position of the branching plate 19 through the gap between the two, and is divided into two directions here. That is, a part of the gas is diverted by the branch plate 19, passes through the perforation 18, cools each part of the stove 1 and the grill 2, and then is discharged from the exhaust port 4. The remaining portion continues straight and is discharged from the opening 17. Therefore, since the exhaust area at the exhaust port 4 becomes large, smooth cooling exhaust can be achieved.

Further, since the partition plate 13 and the second guide body 16 are double-layered, the heat insulating effect is excellent, and it is possible to prevent the temperature of each part of the stove 1 and the grill 2 from rising due to the hot air of the oven 3. Further, the functional parts of the grill 2 and the stove 1 can be cooled by the cooling air guided to the grill 2 side by the branch plate 19.

A part of the cooling air is used as combustion air for the stove 1.

Effects of the Invention As described above, according to the present invention, the cooling air that has cooled the electrical components of the high-frequency heating device is exhausted from the opening on the front of the device body, and at the same time the stove and grill are cooled. It is possible to cool each part of the grill and at the same time send in the air necessary to supply combustion air, improving the combustion performance and cooling performance within the main body of the device.
Since temperature rise in each part of the device body can be prevented and the area of the exhaust port at the rear of the device body can be reduced, there are no restrictions on dimensions such as design layout. In particular, according to the present invention, since cooling air passes between the partition plate and the second guide body that partition the oven and the grill, when the oven and microwave oven are used, the cooling air is passed between the partition plate and the second guide body. Since the cooling air acts as a heat insulating air layer, a triple heat insulating structure can be achieved. Moreover, the branch plate and the perforation can be provided in the second guide body at any position and size.

The required amount of cooling air can be sent to the required location, creating an optimal cooling structure.
