Air conditioner self-cleaning control method and air conditioner

Abstract

The invention belongs to the technical field of air conditioners, and particularly provides an air conditioner self-cleaning control method and an air conditioner. In order to judge the opening self-cleaning time of the air conditioner more accurately, the air conditioner self-cleaning control method provided by the invention comprises the following steps that the PM2.5 value of indoor air is acquired; the duration of the PM2.5 value exceeding a set value is recorded; and whether the air conditioner perform self-cleaning based or not is judged based on the duration. According to the control method, whether self-cleaning is performed or not is judged based on the duration of the PM2.5 value of indoor air exceeding the set value, so that the time for starting the self-cleaning of the air conditioner can be judged more accurately. In some examples, the air conditioner self-cleaning control method further combines the differential pressure between the leeward surface and the windward surface of an indoor heat exchanger, the air outlet air volume of the air outlet of the indoor unit or the current value of the fan to judge whether the air conditioner is self-cleaned or not, so that themisjudgment condition of whether the air conditioner is self-cleaning or not is further reduced, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides an air conditioner self-cleaning control method and an air conditioner. Background technique [0002] The air conditioner is a device that can cool / heat the room. As time goes by, the dust accumulation on the indoor and outdoor units of the air conditioner will gradually increase. After the dust accumulation reaches a certain level, a large number of bacteria will grow, especially in the indoor When the air flows through the indoor unit, it will carry a lot of dust and bacteria, so the air conditioner needs to be cleaned in time. [0003] In the prior art, the cleaning methods of the air conditioner include manual cleaning and self-cleaning of the air conditioner. It is time-consuming and labor-intensive to use manual cleaning. It is necessary to disassemble the various parts of the air conditioner and then clean them. After cleaning, each part needs to be reins...

Problems solved by technology

[0003] In the prior art, the cleaning methods of the air conditioner include manual cleaning and self-cleaning of the air conditioner. It is time-consuming and labor-intensive to use manual cleaning. It is necessary to disassemble the various parts of the air conditioner and then clean them. After cleaning, each part needs to be reinstalled. assembled

Therefore, many current air conditioners have adopted the self-cleaning method. However, affected by factors such as the actual installation location of the air conditioner, the actual operating status, and the indoor environment, the air conditioner cannot automatically judge the timing of turning on the self-cleaning control, but requires the user to Judge whether to implement the self-cleaning mode of the air conditioner by yourself, which will lead to: if the self-cleaning mode is turned on frequently, although the cleanliness of the air conditioner can be guaranteed, it will cause waste of energy. If the self-cleaning mode is turned on after a long period of time Mode, it is difficult to ensure the cleanliness of the air conditioner, and may affect the normal use of the air conditioner, while affecting people's health
