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. The control method is capable of realizing air supply by determining thenecessity of air supply in a case where an exhaust device is operated when air in a kitchen or a bathroom is contaminated so as to prevent a pollution source from diffusing into other indoor spaces, and increasing exhaust efficiency and quickly discharging the pollution source to the outside. The control method of the indoor exhaust device of the present invention for the object includes the stepsof: a), discharging indoor air to the outside according to the exhaust device operation information; b) determining whether it is necessary to supply air to the indoor space; and c) if so, generatingthe air supply information to supply air from the air supply device to the room.

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 capable of discharging indoor polluted air to the outside and a control method thereof, and to The control method of the air supply device that supplies air to the room when the exhaust device is described. 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 a...

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
