Problems solved by technology

However, after long-term use of the filter screen, dust will accumulate in the mesh of the filter screen, which will affect the air intake of the condenser. Therefore, it is usually necessary to clean the filter screen regularly. Since the outdoor unit is installed outdoors, it is very difficult to disassemble and has a certain risk, therefore, it is necessary to provide an air conditioner with the function of automatically cleaning the outdoor heat exchanger of the air conditioner

Abstract

The invention belongs to the field of air conditioner equipment, and particularly relates to a self-cleaning device for an outdoor heat exchanger of an air conditioner. The self-cleaning device comprises a driving module, a cleaning module and a control module, wherein a magnetic element is arranged on the driving module and generates electromagnetic force in the power-on process of the driving module, the cleaning module is in driving connection with the driving module to move up and down along the outer surface of the outdoor heat exchanger to carry out cleaning operation, and the control module controls the driving module to be periodically powered on / off in the self-cleaning process; and in the self-cleaning process, when the driving module is powered on, the cleaning module moves upwards along the outer surface of the outdoor heat exchanger under the effect of the electromagnetic force generated by the magnetic element, and when the driving module is powered off, the cleaning module moves downwards along the outer surface of the outdoor heat exchanger under the combined effect of the magnetic force and self-gravity of the magnetic element. The cleaning device of the inventionadopts an electromagnetic driving mode, the cost is low, the occupied space is small, and the air inlet amount is not affected.

Description

technical field [0001] The invention belongs to the field of air conditioning equipment, and in particular relates to a self-cleaning device for an outdoor heat exchanger of an air conditioner, an air conditioner and a control method. Background technique [0002] At present, the outdoor units of air conditioners are installed outdoors. Due to the harsh outdoor environment and the fact that the outdoor units of the air conditioners have been exposed without any protection measures, long-term work and operation have caused the condensers of the outdoor units to accumulate dust, and the dust cannot be cleaned in time. Cleaning, when the dust accumulation is serious, it will block the air intake of the outdoor condenser, resulting in a decrease in air volume, affecting the performance of the outdoor heat exchanger and reducing the service life of the compressor. In order to solve the problem of dust accumulation in the condenser, a filter screen is usually installed on the outd...
