[ In the display unit of the controller of the air conditioner 100, the use state of the kitchen appliance 300 may be displayed.

A control method of the air conditioner according to the present invention will be described with reference to FIG.

Step S101 is a step of registering the sensor module 200 in the controller of the air conditioner 100. [

An appliance installed in the controller of the air conditioner 100 is operated to perform a device search. When the device search is executed, communication is established between the communication units 150 and 220 to detect the sensor module 200 installed in the kitchen and automatically generate an icon on the display unit of the controller. For example, an icon for the kitchen sensor module 200 is set in the controller, and the sensor module 200 retrieved by the appliance search can be automatically set to match the kitchen icon.

If a plurality of sensor modules 200 installed in the kitchen are searched, it is not matched with the kitchen icon automatically, so that the user can set them manually, such as the kitchen 1 and the kitchen 2.

Step S102 is a step of activating the kitchen appliance 300 connected to the sensor module 200. [ The user opens the gas valve, activates the range, or operates the kitchen hood to cook.

Step S103 is a step in which the operation of the kitchen appliance 300 is detected according to the operation of the kitchen appliance 300 and the operation time of the kitchen appliance 300 is received by the controller 140 of the air conditioner 100. [ Here, the operating time of the kitchen appliance 300 can be regarded as the time sensed by the sensor module 200.

Step S104 is a step of activating the air conditioner 100 and setting the operation time and the operation intensity, which are the operation degree of the air conditioner 100, from the operation time of the received kitchen device 300. [

The air conditioner 100 may be operated in either a ventilation mode or an air cleaning mode. When both the air supply fan 110a and the exhaust air blower 110b are operated and the room air containing dust is blown by the exhaust blower 110b to the inlet 121a of the first air passage 121 The outdoor air is filtered by the filter 125 by the air supply blower 110a and then supplied to the inlet of the second air flow path 122, And is discharged to the room through the outlet 121b of the first air passage 121. [ The air supply blower 110a is operated and the room air is introduced through the inlet 121a of the first air flow path 121 and then filtered by the filter 123 and then supplied to the first air flow path 121 through the outlet portion 121b.

In this case, the starting time of the air conditioner 100 may be set to be started after a lapse of a predetermined time from the starting time of the kitchen appliance 300.

The controller 140 receives the measured indoor temperature from the first indoor temperature sensor 131 and the second indoor temperature sensor 132 and calculates an accumulated operation time of the air conditioner 100 based on the operation of the controller 140 .

The operating time and the operating intensity of the air conditioner set in the controller of the air conditioner 100 after the air conditioner 100 is started for a predetermined time can be determined by the following equation.

[Equation 1]

The operation time of the air conditioner? {The detection time in the sensor module (| the first room temperature - the second room temperature |)} / the cumulative operation time of the air conditioner

Here, the degree of operation of the air conditioner is determined by the operating time of the air conditioner 100 and the operating intensity (the operating intensity or the moving air amount of the blower) or the operating time and the operating intensity of the air conditioner 100 May be included.

In Equation (1), various correction constants are added to determine the operation intensity and the operation time.

It is necessary to purify the air in the room when the operating time of the kitchen device 200 is long. Therefore, the air conditioning is performed in proportion to the operating time of the kitchen device 200 (i.e., the sensing time of the sensor module 200) So that the operation time and the operation intensity of the apparatus 100 can be automatically increased.

In addition, since the indoor air circulates when the air conditioner 100 is operated, the temperature difference according to the indoor position can be reduced. That is, as the air conditioner 100 is operated, indoor air is circulated so that the temperature measured by the first indoor temperature sensor 131 installed on the wall surface of the indoor space and the second indoor temperature sensor 132 installed on the ceiling of the indoor space, The difference in the temperature measured in the case of FIG. Accordingly, when the temperature difference is large, it is determined that the operation of the air conditioner 100 is further required, so that the operating intensity and the operating time of the air conditioner 100 can be set to increase. On the contrary, The operation intensity and the operation time of the microcomputer 100 may be reduced.

In addition, the operating intensity and the operating time of the air conditioner 100 may be set to be in inverse proportion to the cumulative operating time of the air conditioner 100. That is, as the cumulative operation time of the air conditioner 100 increases, it can be seen that the indoor air is cleaned to some extent. Therefore, the operation time of the air conditioner 100 can be set to decrease as the cumulative operation time increases.

Meanwhile, in setting the operating intensity and the operating time of the air conditioner, it is necessary to consider the difference between the sensing time and the room temperature in the sensor module 200 and the cumulative operation time of the air conditioner, The air conditioner 100 may be operated according to Equation 1, or the air conditioner 100 may be operated considering only one or two of the three.

The air conditioner 100 is operated according to the operating time and the operating intensity of the air conditioner 100, and the operating condition includes information received from the sensor module 200, And the operation of the air conditioner 100 is performed in accordance with the changed operating condition.

In step S105, a signal indicating that the operation of the kitchen equipment 300 is stopped during operation of the air conditioner 100 is received from the sensor module 200, or there is no difference in room temperature, The operation of the air conditioner 100 can be stopped when the cumulative operation time of the air conditioner 100 reaches the set value.

According to the control method of the air conditioner, the operation of the kitchen appliance 300 is sensed through the sensor module 200, and the air conditioner 100 is operated in conjunction with the operation of the kitchen appliance 300, It is possible to maintain the environment comfortably, to improve the user's convenience, and to prevent power waste due to unnecessary operation of the air conditioner.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And this also belongs to the present invention.
