Description

[Detailed Description of the Invention] This invention relates to a composite cooking device that integrates a plurality of cooking devices.

BACKGROUND ART Conventionally, as shown in FIG. 1, this type of composite cooking device includes one in which a microwave oven 1, an electromagnetic cooking device 2, and a grill cooking device are arranged in order in the vertical direction. However, in such a composite cooker, it is necessary to cool the various devices in the microwave oven 1, to cool the various devices in the electromagnetic cooker 2, and to discharge cooking smoke from the grill cooker 3. A ventilation path as shown by the arrow in the figure is formed by an intake port, an exhaust port, an exhaust fan, etc. provided in each of the containers 1, 2, and 3. However, each cooker 1, 2, and 3 is equipped with a blower fan, which increases costs. Furthermore, the exhaust air is carried out in multiple locations, making it difficult to properly ventilate the air with the outside, making it difficult to maintain indoor air quality. There were some disadvantages such as getting dirty.

This idea was made in view of the above circumstances, and its purpose is to reduce costs by using only one exhaust fan, and to avoid polluting the indoor air. To provide a highly practical composite cooker that can efficiently ventilate the room and the outdoors without any hassle.

An embodiment of this invention will be described below with reference to the drawings.

In FIGS. 2 and 3, 10 is the main body;
A microwave oven 11, an electromagnetic cooker (dielectric cooker) 12, a grill cooker (heater cooker) 13, and a storage 14 are sequentially arranged in this main body 10 from the top to the bottom. microwave oven 11
An intake port 11a is formed in the lower part of the front side, and an exhaust port 11b is formed in the back surface, and a damper 15a is pivotally mounted inside the exhaust port 11b so as to be openable and closable. An intake port 12a is formed on the front surface of the electromagnetic cooking device 12, and an exhaust port 12b is formed on the back surface, and a damper 15b is pivotally mounted inside the exhaust port 12b so as to be openable and closable. An exhaust port 13a is formed on the back surface of the grill cooker 13, and a damper 15c is pivotally mounted inside the exhaust port 13a so as to be openable and closable.

Here, a damper opening/closing mechanism as shown in FIG. 4 is attached to the damper 15a. That is,
In FIG. 4, a cam 16 that is rotated in the direction of the arrow by a motor (not shown) is provided near the damper 15a, and the eccentric portion of the cam 16 and the damper 15a are connected by a hinge 17. .
In this way, when the cam 16 rotates, the damper 15a opens and closes in the directions of the arrows as the hinge 17 expands and contracts. Circumferential switches 18 and 19 are arranged around the cam 16 and are turned on and off by the protrusion 16a of the cam 16. When the damper 15a is closed, the switch 18 is turned on and the damper 15b is opened. The switch 19 is sometimes turned on. (Damper 1
A similar opening/closing mechanism is also attached to 5b and 15c. ) Therefore, on the back of the main body 1, there are exhaust ports 11b,
A duct 20 is provided that communicates with the inside of the microwave oven 11, the electromagnetic cooker 12, and the grill cooker 13 through 12b and 13a. An exhaust fan 21 is provided in the upper part of the duct 20.

Note that the microwave oven 11 has an operation panel 11p in the lower part of the front surface, and is designed to improve operability since it is located at a high place.

FIG. 5 shows the control circuit. 30 is an AC power supply,
This power source 30 includes power switches 31, 32, 33.
A microwave oven control circuit 34, an electromagnetic cooker control circuit 35, and a grill cooker control circuit 36 are connected through the . And power switch 3
1, 32, 33 and control circuits 34, 35, 36 are connected with circuits for driving the damper opening/closing mechanism described above, respectively. Also, although not shown, any one of the power switches 31, 32, 33
When turned on at any time, the blower fan 21 is activated.

Therefore, when you turn on the power switch 31 and start cooking in the microwave oven 11, the damper 15a opens and the exhaust fan 21 operates, and the air sucked in from the suction port 11a is converted into electronic cooling air. It circulates within the range 11. and,
The cooling air is discharged to the outside through the exhaust port 11b, the duct 20, and the blower fan 21. Also,
The damper 15b is opened during cooking with the electromagnetic cooker 12, and the damper 15c is opened when cooking with the grill cooker 13, and the same exhaust air as described above is performed.

In this way, the exhaust air from each cooking device 11, 12, 13 is received by the common duct 20, and the common duct 2
Since the exhaust air inside the room is collectively discharged to the outside by the common blower fan 21, ventilation with the outside can be efficiently performed without polluting the indoor air. In addition, only one exhaust fan is required, and costs can be reduced. Moreover, dampers 1 are installed at the exhaust ports of each cooking device 11, 12, and 13, respectively.
1b, 12b, and 13b are provided, it is possible to form an appropriate ventilation path according to the usage status of each cooking device, and therefore, the exhaust fan 21 can absorb all the loads in each cooking device at once. This is almost never the case, and a relatively small exhaust fan 21 is sufficient, which is advantageous in terms of cost.

In the above embodiment, a damper is provided at each exhaust port of each cooking device, but as shown in FIG. 40, the damper 40 is set at the lower part when the microwave oven 11 is used, and the damper 40 is set at the upper part when the electromagnetic cooker 12 and the grill cooker 13 are used. When used with the grill cooker 13, the damper 40 is
may be set in a horizontal state, and in this case, the number of dampers is reduced, making it possible to further reduce costs. Moreover, as shown in FIG. 7, if the handle 11T of the microwave oven 11 is provided at the lower part like the operation panel 11P, the operability can be further improved. In addition, this invention is not limited to the above-mentioned embodiment, and it goes without saying that various modifications can be made without changing the gist.

As mentioned above, according to this invention, a duct is provided that communicates with each cooking device, and an exhaust fan is installed in this duct, so it is only necessary to use one exhaust fan, which reduces costs. It is possible to provide a highly practical composite cooker that can reduce the amount of air in the room and also efficiently ventilate the air between the room and the outdoors without polluting the indoor air.
