Problems solved by technology
Since the fixed time is generally a value determined under ideal and specific test conditions, in the actual use of the air conditioner, it is easy to cause problems due to inaccurate control of the self-cleaning function when the actual working conditions change, for example, During the frosting process, the system pressure is too high, which affects the performance of the air conditioner, and the frosting is not enough, which leads to insufficient cleaning, etc.

Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0032] See figure 1 , which is a flowchart of an embodiment of the air-conditioning self-cleaning control method of the present invention.
[0033] Such as figure 1 As shown, the realization of the self-cleaning of the air conditioner in this embodiment includes a control process formed by the following steps:
[0034] Step 11: Activate the self-cleaning function.
[0035] Step 12: Continuously obtain the real-time indoor unit coil temperature and real-time indoor air humidity, obtain the frosting time corresponding to the real-time indoor air humidity as the real-time frosting time, and obtain the defrosting time corresponding to the real-time indoor air humidity as Real-time defrosting time.
[0036] The real-time indoor unit coil temperature...

The invention discloses a self-cleaning control method for an air conditioner. The self-cleaning control method includes the steps that the self-cleaning function is started; the real-time indoor unit coiled pipe temperature and the real-time indoor air humidity are continuously obtained, and the real-time frosting time and the real-time defrosting time which correspond to the real-time indoor air humidity are obtained; the indoor unit frosting control process is executed; timekeeping is started when the real-time indoor unit coiled pipe temperature is lowered to the first set coiled pipe temperature, and the time is used as the first timekeeping time; in the process of executing frosting control, if the real-time indoor unit coiled pipe temperature is larger than the second set coiled pipe temperature and the first timekeeping time reaches the real-time frosting time, the frosting control process is stopped and switched to the indoor unit defrosting control process; and in the process of executing defrosting control, if the real-time indoor unit coiled pipe temperature is small than the third set coiled pipe temperature and the defrosting time reaches the real-time defrosting time, the defrosting control process is stopped. By applying the self-cleaning control method, precise control over air conditioner self-cleaning is achieved.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, in particular relates to an air conditioner, and more specifically relates to an air conditioner self-cleaning control method. Background technique [0002] After the air conditioner is placed or used for a long time, there will be a lot of dust in the air conditioner indoor unit. The dust attached to the heat exchanger of the indoor unit will reduce the heat transfer performance of the heat exchanger on the one hand and cause the performance of the air conditioner to decline; Odors are generated in the unit, if not cleaned up in time, it will seriously threaten the health of air conditioner users. [0003] In order to solve the above-mentioned problems caused by the dust attached to the heat exchanger of the air conditioner, the existing air conditioner is equipped with a self-cleaning function. By controlling the operation of the indoor unit, the evaporator is frosted first and then d...
