Step S102 is a step of detecting whether the user stays in the kitchen.

When a user enters the kitchen, the infrared sensor 200 - 3 detects the user's heat to detect that the user has entered the kitchen. In this case, since the user may not cook in the kitchen, in order to determine that the user is cooking in the kitchen, the user does not leave the kitchen for a set time after the infrared sensor 200-3 detects that the user has entered the kitchen. It should be sensed that they are staying without

Also, when the user operates the kitchen hood in the kitchen, the hood operation detection sensor 200 - 2 may detect this. When the operation of the kitchen hood is detected by the hood operation detection sensor 200 - 2 , it may be determined that the user is staying in the kitchen.

The signal detected by the hood operation detection sensor 200-2 and the infrared sensor 200-3 is received by the control unit 150 of the air conditioner 100 by communication between the communication units 220-2, 220-3, and 130. .

Step S103 is a step of detecting a difference between the kitchen temperature and each room temperature.

The room temperature sensors 310 , 320 , and 330 measure the indoor temperature by temperature sensors installed in each room, and the kitchen temperature sensor 200-1 measures the temperature of the kitchen. When the kitchen is not cooking, the temperature of the kitchen can be generally considered to be similar to the temperature of each room. However, in the case of summer and cooling, the correction constant can be added to the temperature of the indoor space in which the air conditioner is operated. can do.

The temperature of each room sensed by the room temperature sensors 310 , 320 , and 330 is received by the control unit 150 of the air conditioner 100 , and the temperature of the kitchen detected by the kitchen temperature sensor 200-1 is communicated by the communication unit 220 . -1,130), and is received by the control unit 150 of the air conditioner 100.

Step S104 is a step of setting the operating time of the air conditioner.

The operating time of the air conditioner 100 may be determined by the following equation.

Equation (1): Air conditioner operation time = (User's kitchen residence time × (Kitchen temperature - average temperature of each room) × correction constant) - (Accumulated operating time of air conditioner × correction constant)

In Equation (1), the operating time of the air conditioner 100 is proportional to the kitchen residence time that the user stays in the kitchen. Since the longer the user stays in the kitchen, the longer the cooking time, the longer the operating time of the air conditioner 100 may be set accordingly.

In addition, the operating time of the air conditioner 100 is proportional to the difference between the kitchen temperature and the temperature of each room, but when there are a plurality of rooms, the temperature of each room may be configured as an average temperature of each room. That is, in the plurality of rooms, there are rooms in which heating or cooling is operated, and there are also rooms in which heating or cooling is not operated. Therefore, when the average temperature of a plurality of rooms is applied, it is possible to more accurately determine whether the kitchen is cooking.

In addition, the operating time of the air conditioner 100 may be set as the time obtained by subtracting the accumulated operating time of the air conditioner 100 from the operating time set to be proportional to the difference between the temperature of each room and the kitchen temperature. When the cumulative operating time of the air conditioner 100 becomes longer, it can be determined that the air condition in the kitchen is improved due to the operation of the air conditioner 100 . Accordingly, by reducing the operating time of the air conditioner 100 by the amount of time multiplied by the correction constant by the accumulated operating time of the air conditioner 100 , power consumption due to unnecessary operation of the air conditioner 100 can be prevented.

In Equation (1), each correction constant may be provided so that each result value is a unit of time. In addition, various values may be assigned to the correction constant to reflect factors not considered in the above equation.

In Equation (1), the operating time of the air conditioner 100 is set in consideration of the user's kitchen residence time, but in Equation (2) below, the operation of the air conditioner 100 is excluded in a manner that excludes the user's kitchen residence time. You can set the time.

Equation (2): Air conditioner operating time = ((Kitchen temperature - average temperature of each room) × correction constant) - (accumulated operating time of air conditioner × correction constant)

Step S105 is a step of operating the air conditioner 100 in one of a ventilation mode and an air cleaning mode according to the operating time set in step S104. When the air conditioner 100 is operated in the ventilation mode or the air cleaning mode, the contaminated air in the kitchen due to cooking is purified or discharged to the outside.

Step S106 is a step of determining whether the operating time set in step S104 has elapsed. If the set operating time has not elapsed, the operation of the air conditioner 100 is maintained, and if the set operating time has elapsed, the operation of the air conditioner 100 is terminated.

When the air conditioner 100 is operated by the above process, it is possible to maintain a comfortable indoor environment, improve user convenience, and automatically operate the air conditioner 100 by sensing the kitchen environment. Power wastage due to unnecessary operation of the conditioner can be prevented.
