Indoor exhaust device, air supply device, and control method thereof

Abstract

An object of the present invention is to provide an indoor exhaust device, an air supply device, and a control method thereof, which are characterized in that air in a kitchen or a bathroom is contaminated to perform gas exhaust by means of an exhaust device and air supply by means of an air supply device. In the meantime, the amount of air supply differs depending on the degree of contamination,thereby preventing the source of the pollution from diffusing into other indoor spaces, also improving the exhaust efficiency, and quickly discharging the source of the pollution to the outside. The control method of the indoor exhaust device of the present invention for achieving the above object includes the following steps: an a) step of operating in an exhaust mode in which the contaminated air in the room is discharged outdoor, and generating air supply information to vary the amount of air supplied from the air supply device to the indoor depending on the degree of pollution of the indoor air; and a b) step of stopping the operation of the exhaust mode if it is determined that the termination condition for terminating the discharge is satisfied.

Description

technical field [0001] The present invention relates to an indoor exhaust device, an air supply device and a control method thereof, in particular to an indoor exhaust device, an air supply device and its control method. Background technique [0002] A kitchen hood, which is one of kitchen appliances, is installed in a kitchen to exhaust combustion gas, food smell, water vapor, etc. generated when cooking food to the outside, thereby preventing air pollution in the kitchen. [0003] Such a kitchen exhauster is provided on an upper side of kitchen equipment including a gas range, an induction cooker, etc., and exhausts gas generated from cooking equipment and gas generated during cooking food to the outside by using an exhaust fan. [0004] In addition, the bathroom is equipped with an exhaust fan to expel the odor and water vapor (humidity) generated while using the bathroom to the outside more quickly. [0005] However, there are problems as follows: Even if the kitchen e...

AI Technical Summary

Problems solved by technology

[0005] However, there are problems as follows: Even if the kitchen exhauster is operated, part of the combustion gas and food smell generated during cooking will not be exhausted to the outside through the exhaust fan but will be diffused into the living room and other rooms; When the odor and water vapor (moisture) generated during the operation are discharged to the outside and the exhaust fan is operated, a part of the odor and water vapor will not be discharged to the outside and diffuse into the room

[0006] Also, there is a problem such as that if the exhaust fan is continuously operated in order to discharge polluted air to the outside, a negative pressure will be formed in the room, so that the exhaust cannot be formed smoothly, and if the exhaust fan is continuously operated in this state fan, the noise and vibration gradually increase

However, if the capacity of the exhaust fan is increased, the size of the exhaust fan will also be increased, so there is a problem that much installation space and cost are required.

[0008] In addition, there are problems in that if the size of the exhaust fan becomes larger, the power consumption is large when the exhaust fan is operated, so that the electricity bill increases, and the vibration and noise become larger when the exhaust fan is operated, thereby Unable to provide a comfortable living environment
