AI Technical Summary

Technical Problem

In air conditioners, existing technologies are prone to contamination or loss when extracting and refilling refrigerant and refrigeration oil, resulting in high costs and manpower consumption, and affecting after-sales maintenance time.

Method used

An oil supply structure was designed, comprising a hydraulic reciprocating device consisting of a storage tank, a drive structure, a compressor, and a solenoid valve. The device achieves rapid recovery and separation of refrigerant and refrigeration oil through the thrust of the hydraulic device and the compressor. The solenoid valve controls the on/off of the pipeline, enabling the secondary use of the refrigeration oil.

Benefits of technology

It enables rapid recovery and separate storage of refrigeration oil and refrigerant, reducing costs, minimizing manpower consumption, improving recovery efficiency, and without affecting the lifespan of the product's built-in compressor.

Abstract

This invention provides an oil supply structure and an air conditioner. The oil supply structure includes: a body with an oil supply pipeline; a storage tank with a storage cavity connected to the oil supply pipeline; a drive structure connected to the storage tank to flow oil from the oil supply pipeline into the storage cavity; a compressor connected to the oil supply pipeline to drive the flow of oil within the pipeline; and a compressor connected to the storage tank to drive the flow of oil within the storage tank. This invention solves the technical problem of excessively high costs associated with supplying oil to air conditioners in related technologies.
