No-water cleaning device of central air-conditioning evaporator

Abstract

The invention discloses a no-water cleaning device of a central air-conditioning evaporator. The no-water cleaning device comprises a steam cleaning assembly, a detergent spraying assembly, a belt wheel driving assembly and a gantry-shaped bracket, wherein the steam cleaning assembly comprises a steam generator, a rigid steam delivery pipe and a steam conveying hose; the rigid steam conveying pipe is provided with a plurality of high-pressure steam shower nozzles in parallel along an axial direction. When the no-water cleaning device is used for cleaning, firstly, the belt wheel driving assembly is used for driving a rigid detergent conveying pipe to vertically move along an air conditioning external unit, and detergent output from a water pump is sprayed into a cooling fin of the air-conditioning evaporator in an atomization way by the high-pressure atomizing shower nozzles; then, steam is generated by the steam generator, the steam is sprayed into cooling fins of the air-conditioning evaporator through the high-pressure steam shower nozzles, the cooling fins of the air-conditioning evaporator are cleaned by steam flow to avoid water resource waste, and in addition, bacteria on the cooling fins of the air-conditioning evaporator can be killed by steam cleaning to improve the cleanness of air conditioning air; meanwhile, a cleaning process is automatically finished, and the no-water cleaning device has the advantages of convenience in operation and high working efficiency.

Description

technical field [0001] The invention relates to an air conditioner cleaning device, in particular to a cleaning device for an external unit of a central air conditioner. Background technique [0002] As a common air temperature adjustment device, central air conditioners are widely used in various places such as office buildings and shopping malls. [0003] During the long-term use of the central air conditioner, a large amount of dust adheres to the heat dissipation fins of the evaporator in the external unit. If it is not cleaned, its heat dissipation effect will be greatly reduced, and the cooling performance of the air conditioner will be reduced. [0004] In the prior art, the cleaning method of the central air conditioner’s external unit is generally manual washing with water pipes. This cleaning method not only has low work efficiency and poor cleaning effect, but also wastes a lot of water resources, especially when the air conditioner is away from the water source. ...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the purpose of the present invention is to provide a central air-conditioning evaporator waterless cleaning device to solve the serious waste of water resources, low work efficiency, inconvenient operation, and inability to manually use water pipes to flush the central air-conditioning external unit in the prior art. Very good to reduce the bacteria content in the air conditioning wind and other problems
