Problems solved by technology

Under normal circumstances, the outdoor unit of the air conditioner uses an axial flow fan, and the fan blades have a certain running direction. If the fan is reversed with a large torque, the life of the fan may be reduced, and the dust removal effect is not very good.
In addition, the above-mentioned dust removal method does not adopt different dust removal methods for air conditioners with different types of heating and cooling air conditioners, so that better dust removal effects cannot be achieved.

Embodiment 1

[0016] Such as figure 1 In the air-conditioner dedusting method of the present invention, when the controller of the air conditioner receives the instruction of dedusting, it first obtains the image data of the heat exchanger of the current outdoor unit through the image capture device installed on the outdoor unit, and compares the image data with the image data set on the Compare the original data of the outdoor unit heat exchanger stored in PLASH, RAM or ROM storage units on the circuit board of the outdoor unit. If it is judged that dust removal is not needed, no response is made; if it is judged that dust removal is required, the type of air conditioner is judged.

[0017] If the air conditioner is a heating and cooling air conditioner, the air conditioner is heated and defrosted, and at the same time, the outdoor fan is forced to rotate forward or reverse for a set period of time, so that the water and dust generated by defrosting are discharged outside the air conditione...

Embodiment 2

[0023] Such as figure 2 In the air-conditioner dedusting method of the present invention, when the controller of the air conditioner receives the dust-removal instruction, it first obtains the image data of the heat exchanger of the current indoor unit through the image capture device installed in the indoor unit, and compares the image data with the image data set in the indoor unit. Compare the raw data of the indoor unit heat exchanger stored in PLASH, RAM or ROM storage units on the circuit board of the indoor unit. If it is judged that dust removal is not needed, no response will be made; if it is judged that dust removal is required, the type of air conditioner will be judged.

[0024] If the air conditioner is heating and cooling, turn on the indoor fan for cooling. When dew condensation is detected on the indoor fan, the compressor runs for a set time, and the outdoor fan rotates forward or reverse for a set time, so that the water and dust generated by defrosting are...

Abstract

The invention relates to a dust collecting method for air conditioners. The dust collecting method includes: defrosting by controlling an air conditioner fan to rotate through a controller of an air conditioner, and collecting dust on a heat exchanger by flowing water generated by air blowing of the air conditioner fan and defrosting. By the dust collecting method for the air conditioners, accumulated dust on the air conditioners can be safely and conveniently collected, different dust collection modes can be adopted for different types of air conditioners, better dust collecting effect can be realized, dust cannot be accumulated much after long-term running of the air conditioners, and performances of the air conditioners can be kept stable and cannot be weakened too much.

Description

technical field [0001] The invention relates to a method for removing dust from an air conditioner. Background technique [0002] Air conditioners have become a part of people's lives as refrigeration or heating equipment, and can improve the comfort of people's lives. However, the operation of the air conditioner needs to consume more electric energy, and the operation cycle of the air conditioner is also longer. Generally, there will be no obvious failure after running for 10 years or more. As the air conditioner runs longer, its outdoor opportunities will accumulate thicker dust, especially in harsh outdoor conditions, and the speed at which it will accumulate dust will be faster. Due to the accumulation of dust in the outdoor unit of the air conditioner, its ventilation effect and heat transfer effect will become poor. If it is necessary to achieve the previous cooling or heating capacity, it will inevitably consume more electric energy and cause greater waste. In orde...
