Embodiment

[0048] see figure 1 , figure 1 It is a flowchart of a control method for automatic cleaning of an outdoor unit of an air conditioner provided by an embodiment of the present invention. The air conditioner includes an indoor unit and an outdoor unit, the indoor unit includes an inner fan, and the outdoor unit includes a compressor, an outer fan and fins. Such as figure 1 As shown, the method includes:

[0049] Step S101, receiving a control instruction for cleaning the outdoor unit input by the user;

[0050] Step S102, in response to the control instruction, control the air conditioner to turn on the heating mode;

[0051] Step S103, controlling the outdoor fan to run at the lowest wind speed, and the compressor to run at the first frequency until the running time under the first preset condition reaches the first preset time, so that the gap between the fins produce condensation;

[0052] Specifically, the first frequency corresponds to the outdoor ambient temperature, ...

Abstract

The invention discloses a control method and device for automatic cleaning of an outdoor unit of an air conditioner and an air conditioning system. The method comprises the steps that the air conditioner is controlled to start a heating mode, an external fan is controlled to run at the minimum wind grade, and a compressor runs at first frequency until running time on a first preset condition reaches first preset time to make fins condense; next, the external fan is controlled to stop running, and the compressor runs at second frequency until running time on a second preset condition reaches second preset time to make the fins frost; lastly, the air conditioner is controlled to switch into a refrigeration mode from the heating mode, the external fan and an internal fan are controlled to run at the wind grade corresponding to the outdoor environment temperature, and the compressor runs at third frequency until running time on a third preset condition reaches third preset time to make the fins defrost. According to the technical scheme, automatic cleaning of the outdoor unit can be achieved just through moisture in outdoor air, and therefore cost can be effectively saved.

Description

technical field [0001] The invention relates to the field of control technology, in particular to a control method, device and air conditioning system for automatic cleaning of an outdoor unit of an air conditioner. Background technique [0002] The outdoor unit of the split air conditioner is placed outdoors all the year round, which causes a lot of dust to accumulate between the fins, and sometimes even completely blocks the outdoor unit, seriously affecting the performance and reliability of the air conditioner. At present, it generally requires relevant personnel to wipe the fins to remove dust, which is cumbersome and inefficient. In order to solve the various inconveniences of manual dust removal by related personnel, air conditioners equipped with automatic cleaning devices and automatic water shower devices have also appeared recently, which can realize automatic cleaning of the outdoor unit of the air conditioner. [0003] However, because the current technology ne...
