Connecting pipe assembly and refrigerator

Abstract

The present invention provides a connecting pipe assembly and a refrigerator, wherein the connecting pipe assembly includes: a transition pipe, the first end of which can be connected to the capillary of the refrigerator; The small end of the pipe can be connected with the second end of the transition pipe, and the large end of the expanding pipe can be connected with the evaporation pipe of the evaporator of the refrigerator. The connecting pipe assembly provided by this technical solution connects the small end of the expander with the transition pipe, so that there is no gap between the wall of the expander and the transition pipe, so as to avoid the problem of turbulent vortex of the refrigerant caused by the gap. Reduce the noise generated when the refrigerant passes through the connecting pipe assembly.

Description

technical field [0001] The invention relates to the field of household appliances, more specifically, to a connecting pipe assembly and a refrigerator including the connecting pipe assembly. Background technique [0002] In the existing technology, such as figure 1 and figure 2 As shown, the refrigeration system of the refrigerator is composed of a compressor, a condenser, a filter, a capillary tube 2*, a freezing evaporation tube 6*, a refrigeration evaporation tube 7*, and an air return pipe 8* connected in order to form a circuit. The refrigerant in the condenser is High-temperature and high-pressure liquid state, in the evaporator is a low-temperature and low-pressure gas-liquid two-phase state. When the high-temperature and high-pressure liquid refrigerant enters the evaporator through the capillary 2*, at the outlet of the capillary 2*, due to the sudden change in pressure, the refrigerant will be injected instantly, expand into a gas-liquid two-phase state, and emi...

AI Technical Summary

Problems solved by technology

When the high-temperature and high-pressure liquid refrigerant enters the evaporator through the capillary 2*, at the outlet of the capillary 2*, due to the sudden change in pressure, the refrigerant will be injected instantly, expand into a gas-liquid two-phase state, and emit air jetting noise; In order to reduce the expansion and ejection noise of the refrigerant airflow, the researchers added a connecting tube assembly 1* between the capillary tube 2* and the evaporating tube. The inside of the tube assembly 1* expands gradually to reduce noise, but the transition tube 11* is inserted into the expander tube 12* and connected with the expander tube 12*, so that the outer tube wall of the transition tube 11* and the expander tube 12 * There is a gap between the walls of the inner tube, and when the refrigerant flows into the gap, a "turbulent vortex" will be generated, resulting in loud noise
