Problems solved by technology

[0002] For multi-system refrigerators, especially for the freezer door, in a high-temperature environment, it will be difficult to open the door for the second time after opening the door for the second time. There are three main reasons for this: (1) The evaporator memory of the refrigerator Water, the liquid level is higher than the drain port, forming a liquid seal, and the air inside and outside the compartment is not conductive; (2) After the door is opened for the first time, hot air enters the freezer. Due to the low temperature of the freezer, the hot air expands and contracts rapidly after entering, Make the internal pressure of the freezer decrease sharply to form a negative pressure state; (3) The door seal of the door body has magnetic attraction and the door seal itself has an airbag structure. The door is difficult to open

Abstract

The invention discloses a refrigerator. The refrigerator comprises a plurality of chambers, and further comprises a pipeline assembly, wherein the pipeline assembly comprises a main pipe and a plurality of branch pipes, and the branch pipes correspond to the chambers in a one-to-one mode, each branch pipe is connected with one chamber and the main pipe, the far port of the main pipe is sealed by liquid, and branch pipes communicated with each other so as to achieve the pressure balance of the chambers.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a pipeline structure for reducing the negative pressure of a compartment. Background technique [0002] For multi-system refrigerators, especially for the freezer door, in a high-temperature environment, it will be difficult to open the door for the second time after opening the door for the second time. There are three main reasons for this: (1) The evaporator memory of the refrigerator Water, the liquid level is higher than the drain port, forming a liquid seal, and the air inside and outside the compartment is not conductive; (2) After the door is opened for the first time, hot air enters the freezer. Due to the low temperature of the freezer, the hot air expands and contracts rapidly after entering, Make the internal pressure of the freezer decrease sharply to form a negative pressure state; (3) The door seal of the door body has magnetic attraction and the ...
