Problems solved by technology
[0005] In order to solve the above problems in the prior art, that is, in order to solve the problem that the existing air conditioner passes the judgment of the single condition of the fan current of the indoor unit, it is easy to cause the air conditioner to frequently execute the self-cleaning mode due to misjudgment, the present invention provides a The self-cleaning control method for an air conditioner includes an indoor unit. The self-cleaning control method includes: when the air conditioner is in cooling operation, obtaining the coil temperature of the indoor unit, the dew point temperature of the air, and the monthly temperature of the fan of the indoor unit. Current average value and last month current average value; according to indoor unit coil temperature, air dew point temperature, current average value this month and last month current average value, determine whether to implement self-cleaning mode for indoor units

Embodiment Construction
[0020] The preferred embodiments of the present invention will be described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention. For example, although the present invention is described in conjunction with the indoor unit of an air conditioner, since the indoor unit and outdoor unit of the air conditioner are of symmetrical structure, the principle of the present invention is also applicable to the outdoor unit during heating operation of the air conditioner. Self-cleaning, at this time, the fan current of the indoor unit in the judgment condition is replaced with the fan current of the outdoor unit, and the coil temperature of the indoor unit is replaced with the coil temperature of the outdoor unit.

The present invention relates to the technical field of air conditioners, and aims to solve a problem in the prior art in which an air conditioner performs determination based on a single condition, namely a current value of a fan in an indoor unit, and as a result is likely to frequently perform self-cleaning operations due to erroneous determination. Provided is a self-cleaning control method for an air conditioner comprising an indoor unit, comprising: when the air conditioner is performing a cooling operation, acquiring a temperature of a coil in the indoor unit, a dew point temperature of air, and a current month average current value and a previous month average current value of a fan in the indoor unit; and determining, according to the temperature of the coil in the indoor unit, the dew point temperature of air, the current month average current value and the previous month average current value, whether to cause the air conditioner to execute a self-cleaning operation. The present invention enables an air conditioner to perform self-cleaning operations under reasonable conditions both when there is condensation and when there is not condensation, and can prevent the air conditioner from wasting energy.
Description
Technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a self-cleaning control method for air conditioners. Background technique [0002] Air conditioners are equipment that can cool / heat indoors. As time goes by, the dust on the indoor unit and outdoor unit of the air conditioner will gradually increase. When the dust accumulates to a certain extent, a large number of bacteria will breed, especially indoors. When the air flows through the indoor unit, it will carry a lot of dust and bacteria, so it is necessary to clean the air conditioner in time. [0003] In the prior art, the cleaning methods of the air conditioner include manual cleaning and self-cleaning of the air conditioner. Manual cleaning is time-consuming and laborious. It is necessary to disassemble the parts of the air conditioner before cleaning. After the cleaning is completed, the parts need to be renewed. Assembled. Therefore, many air conditioners nowa...
