Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2019/129063
Kind Code:
A1
Abstract:
A refrigerator comprises an evaporator (70), a capillary tube connected to the evaporator (70), and a first fluid conveying tube connected to the evaporator (70) and the capillary tube. The first fluid conveying tube comprises a first transition tube segment (110). A first inner tube (111) extending in an extension direction of the first transition tube segment (110) is disposed in the first transition tube segment (110). An inlet end of the first inner tube (111) communicates with an outlet end of the capillary tube. An outlet end of the first transition tube segment (110) communicates with the evaporator (70), such that fluid flows in the first inner tube (111). Multiple extension portions (112) extending in a fluid downstream flow direction are formed at an outlet end of the first inner tube (111). The multiple extension portions (112) are sequentially disposed along a circumferential direction of the first inner tube (111), and the multiple extension portions (112) are inwardly bent in the fluid flow direction so as to crush and disperse the fluid flowing out of the first inner tube (111) reducing noise generated by the fluid flow.
