Technical field:

[0001] The utility model relates to a semiconductor cold storage refrigerator with a new door stopper structure, belonging to the technical field of household appliances. Background technology:

At the same time, a soft magnetic strip is embedded in the sealing strip, and the outer shell of the box is a magnetizable metal. After the door stopper is closed, the distance between the door and the box is about 10 mm, and the sealing strip is compressed by about 1.5 mm, which plays a sealing role.

[0003] The existing door stopper structure has the following technical disadvantages: first, the distance between the door boxes is large (about 10 mm), which makes the door look thicker and unsightly; second, the distance between the door boxes is large, and the sealing effect of the refrigerator is worse than that of a refrigerator with a small distance between the door boxes, which is prone to cold leakage; third, a soft magnetic strip is embedded in the sealing strip, and the sealing airbag structure of the sealing strip is simple, with a short compression distance, and the sealing effect of the refrigerator is worse than that of a refrigerator without a magnetic strip in the sealing strip.

[0004] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Utility model content:

[0005] The utility model provides a semiconductor refrigerator with a new door suction structure in order to solve the problems existing in the above-mentioned prior art.

[0007] Furthermore, the first strong magnetic strip and the second strong magnetic strip are strong magnets of different materials and shapes.

[0008] Furthermore, the first strong magnetic strip is a magnet, and the second strong magnetic strip is a magnetizable metal.

[0009] Furthermore, the first strong magnetic strip is a magnetizable metal, and the second strong magnetic strip is a magnet.

[0010] Furthermore, a groove for accommodating the sealing strip is formed at a position on the door body opposite to the sealing strip, and buckle parts are respectively convexly formed on both side walls of the groove.

[0011] Furthermore, the sealing strip comprises a main body portion installed in the groove and an extrusion portion extending beyond the groove, and a boss portion is formed on the main body portion and is buckled and installed together with the buckle portion.

[0012] Furthermore, the height of the extrusion portion is 4.5 mm.

[0013] Furthermore, the distance between the box body and the door body is 1 mm to 3 mm.

[0014] Furthermore, the distance between the box body and the door body is 2.5 mm.

[0015] The utility model has the following beneficial effects: the semiconductor refrigerator with a new door suction structure of the utility model closes the door suction through the principle of attraction between opposite poles of a strong magnet, thereby greatly reducing the distance between the door boxes from the conventional distance of about 10 mm to about 2 mm, reducing the gap, improving the sealing of the door box, and better preventing the refrigerator from leaking cold.
