DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supply / exhaust device for a cooking appliance.

[0002]

2. Description of the Related Art The amount of combustion for each cooking appliance is detected, and the motor damper for each exhaust section and the inverter or motor damper for each supply / exhaust system are controlled according to the combustion amount for each cooking appliance to supply / exhaust air. Is controlled.

[0003]

When the amount of combustion of each cooking appliance corresponding to each exhaust section is small, the motor damper is closed, so that the pressure loss increases and the amount of exhaust becomes smaller than the required amount of exhaust. . For this reason, there is a problem that the supply / exhaust amount is not balanced and the kitchen room becomes a positive pressure.

[0004]

In order to solve the above-mentioned problems, the present invention operates by controlling electric power by an inverter.
Air supply system with an air supply fan
Cooking equipment exhaust category to discharge exhaust gas from baking
A motor for adjusting the amount of exhaust from the cooking appliance exhaust section.
And exhaust that is activated by control power from the inverter
An exhaust system with a fan
Detecting the amount of combustion that occurs, and according to the amount of combustion, the cooking appliance
Opening control of the motor damper in the exhaust section, or
Air supply fan inverter or exhaust in the air supply system
Control by controlling the exhaust fan inverter in the
In a cooking appliance supply / exhaust device for controlling an exhaust amount,
For exhausting the atmosphere inside the cooking equipment installation room to the exhaust system
Atmosphere exhaust section is provided and from this atmosphere exhaust section
A motor damper is provided to adjust the displacement of the
Motor damper in the air segment
Open when the amount is smaller than the rated combustion, and
Closes as the number of
It is characterized in that it has a so that.

[0005]

When the amount of combustion of each cooking appliance corresponding to each cooking appliance exhaust category is small, and the motor damper in the conditioning appliance exhaust category is closed and the pressure loss increases, the exhaust volume becomes smaller than the required exhaust volume. From the atmosphere exhaust category
Open the motor damper in the ambient exhaust section when the amount of combustion in the cooking appliance is small compared to the rated combustion ,
As the amount of combustion increases, the valve is closed to always maintain the required amount of exhaust gas.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numerals 1a, 1b, 1c denote respective cooking appliances, and 2a, 2b, 2c denote respective cooking appliances 1a, 1b, 1c.
It is a cooking appliance exhaust section provided corresponding to. 3a, 3
Reference numerals b and 3c denote motor dampers for the respective cooking appliance exhaust sections 2a, 2b and 2c, and 3d denotes a cooking appliance installation room, that is,
It is a motor damper of the atmosphere exhaust section 2d installed in the kitchen . Reference numeral 4 denotes an exhaust fan of an exhaust system 5, and reference numeral 6 denotes an air supply fan of an air supply system 7.

[0007] The amount of combustion of each cooking appliance 1a, 1b, 1c is:
For example, it can be detected by the flow rate detection of the gas meter 8, and according to each combustion amount, each cooking appliance exhaust section 2a, 2
b, 2c, the opening degree of each damper 3a, 3b, 3c, and at the same time, the exhaust fan 4 of the exhaust system 5 and the air supply system 6
Is controlled by controlling the air supply fan 7. At this time, for example, when the combustion amount of each of the cooking appliances 1a, 1b, 1c is small, as shown in FIG.
The opening degrees of a, 3b, and 3c are closed, the pressure loss increases, and the exhaust amount becomes smaller than the required exhaust amount. At this time, the motor-damping 3d of the atmosphere exhaust partition 2d is to open when the combustion is small, and closed as the combustion quantity increased to the rated combustion, since it is configured to be closed, the cooking appliance exhaust segment 2a , 2b, also the motor-damping 3a of 2c, 3b, 3c they become closed, the atmosphere
The motor damper 3d of the exhaust section 2d is, as shown in FIG.
The open state is maintained, the displacement does not decrease, and the required displacement is secured. Each of the motor dampers 3a, 3b, 3c, 3d is configured such that 80% is fully open and 20% is fully closed.

[0008]

As described above, the present invention has an atmosphere exhaust section with a motor damper of a special configuration that opens when the amount of combustion is small and closes as the amount of combustion increases, so that the amount of combustion decreases. It never decreases the exhaust amount, it is possible to retain good environment within the cooking equipment installation chamber.
