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: obtaining the fan current of the indoor unit, the coil temperature of the indoor unit, and the dew point temperature of the air when the air conditioner is in cooling operation; The fan current of the indoor unit, the coil temperature of the indoor unit and the dew point temperature of the air determine whether to perform self-cleaning mode on the indoor unit

Embodiment Construction
[0020] Preferred embodiments of the present invention are described below with reference to the accompanying 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 the air conditioner, since the indoor unit and the outdoor unit of the air conditioner have a symmetrical structure, the principle of the present invention is also applicable to the outdoor unit when the air conditioner is heating. Self-cleaning, at this time, the fan current of the indoor unit in the judgment condition is replaced by the fan current of the outdoor unit, and the coil temperature of the indoor unit is replaced by the coil temperature of the outdoor unit.

The invention belongs to the technical field of air conditioners and provides a self-cleaning control method for an air conditioner. According to the self-cleaning control method, the problem that anexisting air conditioner is easily caused to frequently execute a self-cleaning mode due to erroneous judgement when the existing air conditioner only judges according to the single condition of the currents of draught fans of an indoor unit is solved. The air conditioner comprises an indoor unit. The self-cleaning control method comprises the following steps: acquiring the currents of draught fans of the indoor unit, the temperature of a coil pipe and the dew point temperature of air during the refrigeration of the air conditioner; and judging whether to execute the self-cleaning mode on theindoor unit according to the currents of the draught fans of the indoor unit, the temperature of the coil pipe and the dew point temperature of air. According to the self-cleaning control method, theair conditioner can execute the self-cleaning mode under reasonable conditions no matter that condensation is generated by the indoor unit or not, and the situations that the air conditioner is causedto frequently execute the self-cleaning mode due to that condensation in the indoor unit is mistaken as accumulated dust, thus the energy is wasted can be avoided.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a self-cleaning control method for 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 reinstalled. Assemble...
