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 coil temperature of the indoor unit and the dew point temperature of the air during the cooling operation of the air conditioner; obtaining the temperature of the indoor unit within a preset time multiple fan current values; calculate the average value of multiple fan current values of the indoor unit; compare the coil temperature of the indoor unit with the dew point temperature of the air; judge whether to implement the self-cleaning mode for the indoor unit based on the comparison results and the average value

Embodiment Construction
[0019] 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.
[0020] Based on the background technology, the existing air conditioner is judge...

The invention belongs to the technical field of air conditioners, and aims to solve the problem that the self-cleaning mode is prone to frequently be executed due to misjudgment by an existing air conditioner on a current single condition of an indoor unit fan. Therefore, the invention provides a self-cleaning control method for an air conditioner. The air conditioner comprises an indoor unit; andthe self-cleaning control method comprises that when the refrigeration operation of the air conditioner is carried out, a coil temperature of the indoor unit and a condensation point temperature of air are obtained; a plurality of fan current values of the indoor unit within a preset time are acquired; the average value of the plurality of fan current values of the indoor unit is calculated; thecoil temperature of the indoor unit and the condensation point temperature of the air are compared; and whether the self-cleaning mode is executed to the indoor unit or not is judged according to thecomparison result and the average value. According to the method, the air conditioner is enabled to execute the self-cleaning mode under the reasonable condition no matter the condensation is generated or not, and the situation that energy of the air conditioner is wasted is 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...
