Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2019/129065
Kind Code:
A1
Abstract:
A refrigerator, comprising a compressor (10), a condenser (20) connected to the compressor (10), and a first fluid transfer pipe connected to the compressor (10) and the condenser (20); the first fluid transfer pipe comprises a transition pipe section (111), an inner pipe (112) extending in an extending direction of the transition pipe section (111) being provided in the transition pipe section (111), an outer wall of the inner pipe (112) and an inner wall of the transition pipe section (111) being spaced apart from each other, and an inlet end of the transition pipe section (111) being in communication with an outlet end of the compressor (10), and an outlet end of the transition pipe section (111) being in communication with an inlet end of the condenser (20) such that some of the fluid entering the transition pipe section (111) flows in a region between the transition pipe section (111) and the inner pipe (112), and some of the fluid flows in the inner pipe (112). Thus, the present invention makes it possible to change the flow velocity of the fluid, so as to achieve the purposes of reducing the flow noise and improving the overall acoustic quality of the refrigerator.
