Referring to fig. 2, in an embodiment of the control method of an air conditioner of the present invention, the control method of an air conditioner includes the steps of:
step S10, acquiring system state information of the air conditioner in a first mode;
step S20, determining that the system state information meets the operation condition of a second mode, and controlling the air conditioner to be switched from the first mode to the second mode;
and step S30, operating according to the operating parameters corresponding to the second mode, and increasing the temperature generated by the action of the air conditioner to a set temperature so as to sterilize the air conditioner.
In this embodiment, when the air conditioner operates in the first mode and the current time satisfies the trigger condition of the second mode, the step S10 is executed. Wherein the first mode can be set to a cooling mode and/or a dehumidifying mode, and the second mode can be set to a high-temperature sterilizing mode. When the air conditioner is switched from the first mode to the second mode, the air conditioner needs to be switched from the cooling state to the heating state so as to raise the temperature of the indoor heat exchanger to the effective sterilization temperature. When the system pressure difference is larger, the phenomena of tangential noise increase of the four-way valve, damage of the four-way valve, burning of the compressor and the like can be caused, and the service life of the air conditioner is shortened. Therefore, system state information of the air conditioner in the first mode may be obtained, wherein the system state information may include a system pressure difference and/or a system temperature difference.
Specifically, when the air conditioner operates in the first mode and it is detected that the current time of the air conditioner satisfies the trigger condition of the second mode, the system high pressure and the system low pressure of the air conditioner in the first mode may be obtained, and then a difference value between the system high pressure and the system low pressure is used as the system pressure difference. It is understood that, in order to obtain the system high pressure and the system low pressure, the air conditioner system is provided with a pressure detection sensor for detecting the system high pressure and the system low pressure of the air conditioner system. And/or acquiring a system condensation temperature and a system evaporation temperature of the air conditioner, then taking a difference value between the system condensation temperature and the system evaporation temperature of the air conditioner as the system temperature difference, and taking the system temperature difference and/or the system pressure difference as the system state information.
It should be noted that, when the air conditioner operates in the first mode, whether the air conditioner currently satisfies the trigger condition of the second mode may be monitored in real time. The trigger condition of the second mode may be set to receive a start instruction of the second mode and/or that the current time is a preset second mode start time. The second mode starting time can be set by a user in a self-defined mode or can be set automatically by the system. For example, the system may set the air conditioner to trigger the second mode when the accumulated operation time length is greater than a preset time length threshold (one week, one month, or 3 months, which is not specifically limited by the embodiment).
Further, after the system state information is acquired, whether the system state information meets the starting condition of the second mode is judged. When the system state information meets the starting condition of the second mode, the air conditioner is directly controlled to be switched from the first mode to the second mode, then the operation parameters corresponding to the second mode are obtained, and the air conditioner is controlled to operate according to the operation parameters corresponding to the second mode, so that the temperature of the indoor heat exchanger can be increased to the sterilization temperature when the air conditioner operates according to the operation parameters corresponding to the second mode, and the air conditioner is sterilized.
In particular, the start condition of the second mode may include that the system pressure difference is less than a preset pressure difference and/or the system temperature difference is less than a preset temperature difference.
