Connecting pipeline of evaporator, evaporator and refrigerator

Abstract

The present invention provides a connecting pipeline of evaporator, an evaporator, and a refrigerator. The connecting pipeline is configured to connect with the refrigerant inlet of the evaporator and comprises first pipeline, second pipeline and inlet pipeline connected in sequence, wherein the inlet pipeline is connected to the refrigerant inlet, and the inner diameter of the first pipeline is larger than the inner diameter of the second pipeline. The connecting pipeline of the evaporator can effectively reduce noise by being configured to comprise first pipeline, second pipeline and inlet pipeline connected in sequence, wherein the inlet pipeline is connected to the refrigerant inlet and the inner diameter of the first pipeline is larger than the inner diameter of the second pipeline.

What is claimed is: 
     
         1 . A connecting pipeline for an evaporator, wherein the connecting pipeline is configured to connect with the refrigerant inlet of the evaporator and comprises a first pipeline, a second pipeline, and an inlet pipeline connected in sequence, wherein the inlet pipeline is connected to the refrigerant inlet, and the inner diameter of the first pipeline is larger than the inner diameter of the second pipeline. 
     
     
         2 . The connecting pipeline according to  claim 1 , wherein
 the length of the first pipeline ranges from 0.02 m to 1.25 m.   
     
     
         3 . The connecting pipeline according to  claim 2 , wherein
 the length of the first pipeline ranges from 0.02 m to 0.9 m.   
     
     
         4 . The connecting pipeline according to  claim 1 , wherein
 the first pipeline is connected upstream to a capillary tube;   the inner diameter of the first pipeline is 0.5-10 mm, the wall thickness of the first pipeline is 0.2-3 mm.   
     
     
         5 . The connecting pipeline according to  claim 1 , wherein
 the first pipeline is welded or integrally drawn with the second pipeline;   the second pipeline is welded or integrally drawn with the inlet pipeline.   
     
     
         6 . The connecting pipeline according to  claim 1 , wherein
 the second pipeline is welded to the first pipeline and/or the inlet pipeline, wherein   the length of the second pipeline's inlet end inserted into the first pipeline is 10-30 mm;   the length of the second pipeline's outlet end inserted into the inlet pipeline is 10-30 mm.   
     
     
         7 . An evaporator equipped with the connecting pipeline as described in  claim 1 . 
     
     
         8 . The evaporator according to  claim 7 , wherein
 the refrigerant outlet of the evaporator is connected to an outlet pipeline;   the evaporator further includes inter-pipe fixators made of flexible material, each inter-pipe fixator has at least two fixing slots, the inter-pipe fixators are connected to at least two of the first pipeline, second pipeline, inlet pipeline, and outlet pipeline through the at least two fixing slots, effectively reducing noise caused by pipeline resonance during the operation of the evaporator.   
     
     
         9 . The evaporator according to  claim 7 , wherein
 the outlet pipeline is welded to the refrigerator's return air pipe, and the outlet pipeline is threaded through one of the fixing slots of the inter-pipe fixators.   
     
     
         10 . The evaporator according to  claim 8 , wherein
 the inter-pipe fixators are positioned in an area of 45-55 mm before and after the diameter change point between the first pipeline and the second pipeline; and/or   the inter-pipe fixators are positioned in an area of 45-55 mm before and after the diameter change point between the second pipeline and the inlet pipeline.   
     
     
         11 . A refrigerator equipped with the evaporator as described in  claim 7 . 
     
     
         12 . The refrigerator according to  claim 11 , further comprising:
 an inner liner defining a storage compartment; and   fixing clamps, consisting of a body part and a clamping part, the inner liner is equipped with an installation port into which the body part is inserted, positioning the clamping part inside the inner liner; the clamping part includes an upper clamping section and a lower clamping section formed by bending forward from the upper end and the lower end of the front side of the body part separately, the upper clamping section bends upwards, and the lower clamping section bends downwards, there is a gap between the front ends of the upper clamping section and the lower clamping section, thus the gap can define a space between the front ends to accommodate the pipelines of the evaporator, and the inner side of the upper clamping section and/or the lower clamping section is equipped with flexible component.
