Water seal structure of refrigerator

Abstract

The invention discloses a water seal structure of a refrigerator. The water seal structure comprises an in-box drainage pipe, an auxiliary water box, a main water box and a water guide part, and an in-box water flow channel is sequentially formed among a water inlet and a water outlet of the in-box drainage pipe, auxiliary water collection space, the water guide part and main water collection space. The main water box is used for containing a large amount of condensate water, the auxiliary water box can form a water seal only through a small amount of water, at the initial stage of drainage, when the condensate water is not much, the auxiliary water box can be filled with the condensate water quickly, the water seal effect is achieved, and cold leakage and odor tainting are prevented. After the auxiliary water box is filled with the condensate water, more water enters the main water box through the water guide part, when the air pressure in the refrigerator changes, if the trend that the in-box drainage pipe absorbs water is generated, due to the fact that the water in the auxiliary water box is is little and absorbed water is also little, the problem that a large amount of water is absorbed back to the interior of the refrigerator is avoided, and performance and user use experience are improved.

Description

Technical field [0001] The present invention relates to a water seal structure of a freezer, and more particularly to a water seal structure of a vertical refrigerator. Background technique [0002] When the refrigerator is working, condensate can be generated, in order to avoid condensate impact device performance and user experience, the condensate will be exported into the water discharge of water, and the drain pipe is inserted into the water to prevent leakage and smell. There are currently several aspects: In order to make the water container can store more condensed water, the volume of the water box needs to be as large as possible, but in the early stage of the drainage, the water does less water, the water cannot close the drain. The water has a water seal, so that the internal and external circulation of the refrigerator generates a cooling problem; when the water does not have a water, the opening and closing of the refrigerator will generate the change in internal ai...

Problems solved by technology

There are several problems at present: In order to store more condensed water in the water box, the volume of the water box needs to be as large as possible, but in the initial stage of drainage, when the water in the water box is less, the water cannot close the outlet of the drain pipe. The water outlet forms a water seal, which makes the inside of the refrigerator communicate with the outside world, resulting in the problem of cold leakage; when the water does not pass through the water outlet to form a water seal, the internal air pressure will change during the opening and closing of the door of the refrigerator, and a large amount of water in the water box will be released. It will be sucked back into the refrigerator, which will cause bad effects; in addition, when the air pressure changes too fast, so that the drain pipe absorbs water quickly, you will hear the obvious "swallowing" noise, which affects the user experience
