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

Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.
[0022] The words expressing position and direction described in the present invention all refer to the direction of water flow, the end close to the upstream is the proximal end, and the end close to the downstream is the distal end.
[0023] In the embodiment of the present invention, the refrigerator of the present invention is specifically explained by taking the drawer type freezer as an example, but it should be noted that the technical spirit involved in the following embodiments can be used in other forms instead on the refrigerator.
[0024] The refrigerator has a plurality of compartments 10,...
