Embodiment Construction

[0026] This embodiment firstly provides a sealing strip 100 for a refrigerating and freezing device, which includes: a sealing strip body 110 , a mounting base 130 , a plurality of sealing sheets 160 and a plurality of snapping parts 170 .

[0027] in the attached Figures 1 to 5 , define the width direction of the sealing strip 100 as the X axis, its length direction as the Y axis, and its thickness direction as the Z axis. Such as Figure 4 As shown, the inside of the weather strip body 110 is defined with several airbags 120 extending along its length direction. The cross-section of the main body of the weather strip body 110 is approximately rectangular, and some side surfaces of the weather strip body 110 have some fold structures for cushioning. The impact force when the door of the refrigerator-freezer is closed.

[0028] The mounting seat 130 is disposed on an outer surface of the weather strip body 110 . The mounting base 130 can also be arrow-shaped, and its funct...

Abstract

The invention provides a refrigeration and freezing device and a sealing strip thereof. The sealing strip comprises a sealing strip body and a ventilation pipe. The ventilation pipe comprises a firstarc pipe wall and a second pipe wall. When a user closes down the door body, thrust applied by the user enables the sealing body to be compressed. The first arc pipe wall deforms. The opposite inner side surfaces of the first arc pipe wall and the second pipe wall are closely attached such that the ventilation pipe is in the blocking state. At this time, the interior and the exterior of the refrigeration and freezing device fail to exchange air. When the user is ready to open the door body, pull force applied by the user enables the first arc pipe wall to restore the original shape. The opposite inner side surfaces of the first arc pipe wall and the second pipe wall are separated such that the ventilation pipe is in the communicated state. At this time, the interior of the refrigeration and freezing device and the exterior can exchange air through the ventilation pipe. Therefore, external air can enter the interior of a storage space so that negative pressure in the storage space is eliminated. The user can more easily open up the door body because the interior of the storage space and the exterior are the same in terms of air pressure.

Description

technical field [0001] The invention relates to the field of refrigeration and freezing, in particular to a refrigeration and freezing device and a sealing strip thereof. Background technique [0002] For traditional refrigerators, due to the low temperature of the air inside the refrigerator, the air pressure inside the refrigerator will be lower than the outside air pressure. After the refrigerator has been refrigerated for a long time, there will be a large pressure difference between the inside and outside of the refrigerator, making it difficult to open the door. Especially for single-door refrigerators or large refrigerators, the above-mentioned problems are particularly serious. [0003] In the prior art, some refrigerators have a one-way valve installed on the back of the refrigerator. When the internal pressure of the refrigerator is lower than the external ambient air pressure, the one-way valve allows outside air to enter the interior of the refrigerator to balan...
