Liquid injection pipe assembly, cleaning device and air conditioner

Abstract

The invention provides a liquid injection pipe assembly which comprises a square pipe and a liquid injection hole formed in the side wall of the square pipe. A transmission mechanism drives the square pipe to move up or down or rotate; after cleaning liquid in a liquid inlet pipe flows into the square pipe, the cleaning liquid is sprayed from the inner portion of the pipe to the outer portion through the liquid spraying hole in the side wall of the square tube, so that an air conditioner can be cleaned; meanwhile, a pipeline is arranged to the square pipe, compared with a common round pipe, the situation that the pipeline is hard to fix in fixing due to a revolved body does not occur, and after the square pipe is fixed, the facing position of the liquid spraying hole in the side wall of the square pipe is relatively fixed as well, so that in the using process, the situation that the position of the liquid spraying hole is changed due to the fact that the cleaning liquid flows in the pipe, and thus the square pipe moves does not occur; and in addition, in machining production, positioning drilling is relatively easily conducted on the surface of the square tube, accuracy of machining manufacturing can be ensured, the production difficulty is reduced, and the market competitiveness of products is improved.

Description

technical field [0001] The invention relates to the field of household appliances, and more particularly, to a liquid spray pipe assembly, a cleaning device and an air conditioner. Background technique [0002] At present, when the air conditioner in the prior art is used for heat exchange for a long time, dust and bacteria in the air are easily accumulated inside the air conditioner, and the interior of the air conditioner is not easy to disassemble and clean. Harmful substances such as bacteria breed, affecting the health of users. [0003] Therefore, it has become an urgent problem to design a liquid spray pipe assembly, a cleaning device and an air conditioner with a simple structure and capable of self-cleaning inside the air conditioner. SUMMARY OF THE INVENTION [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. [0005] Therefore, an object of the present invention is to provide a liquid spray pipe assemb...
