Problems solved by technology
[0002] After the air conditioner is installed and operated for a period of time, the dust filter and heat exchanger of the indoor unit may absorb and accumulate dust or other dirt to varying degrees, which will cause the cooling or heating performance of the air conditioner to decline and the power to increase, affecting the comfort of the user's environment In addition, the accumulation of dust will also induce the growth of mold. If the dust filter is not cleaned in time, it will threaten the health of users. Therefore, it is necessary to design a function that can promptly and accurately remind the indoor unit of the air conditioner that it is full of dust.
[0003] Because the operating environments of indoor units of air conditioners are not the same, the intervals between dirty and clogged phenomena are also different. Therefore, it is not scientific and reasonable to judge whether the indoor fan motor is full of dust based on the accumulated running time of the indoor fan motor.

The invention discloses an air conditioner and a control method of the air conditioner. The air conditioner includes: a motor; a controller, the controller is electrically connected to the motor for detecting the pulse width of the motor and judging whether the absolute difference between the pulse width of the motor and the initial pulse width of the motor is greater than a set threshold; an alarm device, an alarm The device is electrically connected to the controller, and the controller controls the alarm device to work and alarm when the absolute difference between the pulse width and the initial pulse width is greater than or equal to the set threshold. According to the air conditioner of the embodiment of the present invention, by arranging the controller and the alarm device in the air conditioner, the pulse width when the motor of the air conditioner is running can be detected, and according to the change of the pulse width when the internal fan motor is running, the detected pulse width Compared with the absolute difference of the initial pulse width of the motor and the set threshold, it can be judged whether the dust filter is blocked by dust accumulation, and the alarm device will alarm the user when the dust accumulation phenomenon occurs, which has good practicability.
Description
technical field [0001] The present invention relates to the field of home appliances, in particular to an air conditioner and a control method for the air conditioner. Background technique [0002] After the air conditioner is installed and operated for a period of time, the dust filter and heat exchanger of the indoor unit may absorb and accumulate dust or other dirt to varying degrees, which will cause the cooling or heating performance of the air conditioner to decline and the power to increase, affecting the comfort of the user's environment In addition, the accumulation of dust will also induce the growth of mold. If the dust filter is not cleaned in time, it will threaten the health of users. Therefore, it is necessary to design a function that can promptly and accurately remind the indoor unit of the air conditioner that it is full of dust. [0003] Because the operating environment of the indoor unit of the air conditioner is not the same, the interval time for the o...
