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 according to an existing air conditioner, only a single condition of a fan current of an indoor unit is judged, so that the air conditioner is easy to frequently execute a self-cleaning mode due to misjudgment. Therefore, the invention provides a self-cleaning control method for an air conditioner.The air conditioner comprises an indoor unit. The self-cleaning control method comprises the steps of when the air conditioner runs at a cooling mode, acquiring the coil temperature of the indoor unit, the dew point temperature of air, a real-time current value of a fan of the indoor unit, a current average value of the current month and a current average value of the last month; and judging whether the self-cleaning mode is executed or not for the indoor unit according to the coil temperature of the indoor unit, the dew point temperature of the air, the real-time current value of the fan ofthe indoor unit, the current average value of the current month and the current average value of the last month. According to the self-cleaning control method for the air conditioner provided by the invention, no matter the air conditioner produces dews or not, the air conditioner can execute the self-cleaning mode under a reasonable condition, so that the occurrence of the phenomenon of energy waste of the air conditioner 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...
