Drain pipe for refrigerator and refrigerator provided with the same

Abstract

The invention provides a drain pipe for a refrigerator, which comprises a main pipe with a first end and a branch pipe with a third end connected to the main pipe, the first end of the main pipe is provided with a The main pipe cover with one-way water flow outside, the third end of the branch pipe is provided with a branch pipe cover facing the branch pipe for one-way ventilation, and an angle α less than 90° is formed between the end surface of the main pipe cover and the horizontal plane. With the drain pipe according to the present invention, heat exchange can be effectively prevented by providing a pipe cover at the end of the main pipe for one-way water flow toward the outside of the main pipe. In addition, the cover of the main pipe tube is a slope structure, which can prevent the drainage pipe from being attached to the evaporating dish and hinder effective drainage. At the same time, a branch pipe is added to the main pipe of the drain pipe, and a pipe cover facing the drain pipe for one-way ventilation is installed at the end of the branch pipe, which can effectively prevent heat exchange and avoid the laborious opening of the door and buzzing noise caused by the failure to return air smoothly when opening the door. question.

Description

technical field [0001] The present invention relates to a refrigerator, and more particularly, to a drain pipe for a refrigerator. Background technique [0002] The refrigerator drain is the only direct path to the atmosphere when the refrigerator is closed. The current refrigerator drain pipe mainly adopts two structures, one is the design of a straight pipe with a drain pipe cover, which achieves the purpose of drainage by making a cut on the drain pipe cover, or uses a one-way unimpeded drain pipe cover to realize one-way drainage and isolate Outside air; the biggest problem with this design is that the air cannot flow back effectively when the door is opened, resulting in laborious door opening and buzzing noises, which may even cause water to flow back into the box; the other is the design of the trap structure drain pipe , this structure can effectively prevent the convection of hot and cold air to achieve energy-saving effect; however, when the refrigerator door is o...
