Description

[Detailed description of the invention] Industrial applications The present invention is aimed at reducing carbon dioxide gas and oil generated by cooking appliances.

This relates to a cooking exhaust system that exhausts smoke, odors, etc. to the outdoors.

BACKGROUND OF THE INVENTION Conventionally, this type of cooking exhaust system has a structure as shown in FIG. In the figure, a canopy 16 that covers the cooking device 14 is provided above a cooking table 15 equipped with a cooking device 14 such as a gas stove, and an air inlet 17 and a duct connected to the inlet port 17 and a blower are used to exhaust air for cooking. configured the device.

In the above configuration, oil and smoke generated during cooking.

Odors and the like were sucked in from the air inlet 17 along the canopy 16 by operating a blower and discharged outdoors through a duct (for example,
Publication No. 7).

Problems to be Solved by the Invention In such a conventional configuration, the area of the intake part of the intake port 17 is constant, and even when one combustion part of the cooker 14 is being combusted, both combustion parts are being combusted. Even when cooking, it is necessary to use the same amount of air to exhaust smoke, etc., and when one combustion part is burning, it wastes electricity and removes oil and carbon dioxide generated during cooking. There was a problem in that indoor air that was not being used was also exhausted.

The present invention has been made to solve these problems, and it is an object of the present invention to provide an efficient cooking exhaust device that exhausts only air containing oil and carbon dioxide generated during cooking.

Means for Solving the Problems In order to solve this problem, the present invention provides an air intake port at the rear upper part of the cooking device, and provides an air intake port in accordance with the combustion state of the combustion section of the cooking device. This cooking exhaust device is provided with a plurality of opening/closing plates for opening and closing.

Furthermore, a variable air volume blower is provided that changes the air volume taken in from the intake port depending on the combustion state of the combustion section.

Effect: With this configuration, only the opening/closing plate at the rear and upper part of the burning combustion section opens to allow intake, and only the air containing oil and carbon dioxide near the combustion section is taken in through the open intake port. and will be discharged. In addition, since the intake air volume is made variable according to the number of burning combustion parts, it is possible to prevent unnecessary intake of outside air. Let me explain based on this. An air intake port 3 is provided at the rear upper part of the cooking table 2 on which the cooking device 1 is placed, an airflow guide plate 6 which is a top plate is provided at the top of the cooking table 2, and side plates 8 are provided on the left and right sides of the cooking table 2. will be established. The airflow guide plate 6, back plate 7, and side plate 8 form an integral cabinet.◇The air intake port 3 is connected to a blower 13 installed inside the cooking table 2 via a duct 12. The cooking device 1 has three combustion sections 4a, 4b, and 4a that are ignited by ignition switches 9a, 9b, and 9c. 1o is a control means that instructs the stepping motor 11 to open and close the opening/closing plates 5a, 5b, and 5c in conjunction with the ignition states of the ignition switches ga, gb, and 9c, and also instructs the variable air volume blower 13 to operate the air volume. The stepping motor 11 is directly connected to the rotating shaft of the opening/closing plate, and opens and closes the opening/closing plate by rotation of the motor shaft. Also, the variable air volume blower 13 is strong.

This is a blower that can vary the air volume in three stages, from medium to low.

In the above configuration, the ignition switch 9a of the cooker 1.

When the combustion parts 4a and 4b are ignited at step 9b, the control means 10 linked to the ignition switch starts the stepping motor 11.
to open the opening/closing plates sa and sb, and also instructs the variable air volume blower 13 to operate at a medium air volume. Upon receiving the instruction, the stepping motor 11 rotates to close the opening/closing plate s.
a, 6b are opened, and at the same time, the variable air volume blower 13 also starts operating at a medium air volume, and oil gas is generated from the combustion sections 4a and 4b.

Smoke, odors, etc. are exhausted from the rear open air intake. At this time, the intake port at the rear of the combustion part 4c that does not burn is the opening/closing plate 5.
It is cut off by C. Next, when the combustion section 4a is extinguished, the control means 10 causes the stepping motor 11 to switch to the opening/closing plate 5.
Instruct to shield the variable air volume fan 1.
Instruct 3 to operate at low air volume. Upon receiving the instruction, the stepping motor 11 rotates to shield the opening/closing plate 5a, and at the same time, the variable air volume blower 13 is also switched from a medium air volume to a low air volume.
Smoke, odors, etc. are exhausted through the open intake vent at the rear.

If all three combustion parts 4a, 4b, and 4c are ignited, all the opening/closing plates 5a, 6b, and 5c are also opened, and the variable air volume blower 13 is operated at a strong air volume.

As described above, according to this embodiment, only the intake port at the rear of the combustion section where combustion is being opened is opened, and the intake air volume is also changed in stages, so that oil and gas near the combustion section are opened.

The effect is that only smoke and odors are exhausted, and indoor air that does not contain oil, smoke, or odors is not exhausted.

In this example, three opening/closing plates were provided, and the variable air volume blower was variable in air volume in three stages, but it is not necessary to have three or three stages, and the point is that the number of opening/closing plates can be adjusted according to the number of combustion parts, calories, etc.
It is only necessary to select the position and area of the intake port and the air volume of the blower so that oil, smoke, and odor can be efficiently discharged.

Effects of the Invention As described above, according to the present invention, since the intake port is opened and closed according to the combustion state of the combustion section of the cooking device, carbon dioxide and oil gas generated in the combustion section can be removed.

It can be an efficient cooking exhaust device that only exhausts smoke, odors, etc. ◇ Also, since the intake air volume is changed according to the combustion state, even more efficient exhaust is possible.
