[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] Please see Figure 1-3 This utility model discloses a double sealing strip structure for refrigerators, which solves the problem of poor sealing and heat insulation effect of existing refrigeration products. It includes: a door seal bracket 1 set on the refrigerator door 100 and a cabinet profile 2 set on the refrigerator cabinet 200. One end of the cabinet profile has an inner sheet metal insertion port 21 and the other end has an outer sheet metal splice 22. The cabinet profile is installed on the refrigerator cabinet through the inner sheet metal insertion port and the outer sheet metal splice 22. After the refrigerator cabinet is foamed, the cabinet profile will be bonded to the refrigerator cabinet. The door seal bracket has a hook 11 that connects to the refrigerator door. The door seal bracket is fixed on the door and will be bonded to the refrigerator door after the refrigerator door is foamed.
[0023] Specifically, the door seal holder is made of rigid PVC and designed with a slope to increase the thickness of the refrigerator door foam layer, which is more conducive to the insulation of the refrigerator door. It has a first slot 12 and a second slot 13. A first sealing strip 3 is engaged in the first slot, and a second door seal 4 is engaged in the second slot. The first and second sealing strips are used to seal the cold air passage 5 formed between the cabinet profile and the door seal holder to prevent cold air leakage from the refrigerator cabinet. In this embodiment, the first sealing strip is made of soft PVC, including... The sealing strip body 31, the first airbag 32 formed in the sealing strip body, and the first latch 33 set on the sealing strip body and snapped into the first slot are used to seal the cold air passage. The first airbag supports the entire sealing strip body to completely seal the cold air passage. In addition, a third fin 34 for blocking cold air is provided on the end of the sealing strip body near the refrigerator cabinet. One end of the third fin is integrally formed on the sealing strip body, and the other end abuts against the inner wall of the door seal seat, which can better prevent cold air leakage inside the refrigerator body.
[0024] Specifically, the second door seal includes a door seal body 41, a second airbag 42 formed within the door seal body, a magnetic strip 43 disposed on the end face of the door seal body near the refrigerator cabinet, and a second latch 44 disposed on the door seal body and snapped into the second slot. The door seal body is attached to the refrigerator cabinet by magnetic adsorption. The second airbag supports the door seal body for secondary sealing of the cold air passage. The door seal body has a sloped surface 45 that matches the corner surface of the door seal seat, and has a first fin 46 and a second fin 47 for sealing the gap between the sloped surface and the corner surface of the door seal seat. The door seal body is made of soft PVC. The double-fin structure can play a better sealing role. The first fin and the second fin are integrally formed on the door seal body and abut against the corner surface of the door seal seat to prevent cold air loss.
[0025] Specifically, a striped positioning part 23 is provided on the end face of the cabinet profile that contacts the sealing strip body, which increases friction and enhances the stability of the first sealing strip.
[0026] Working principle: The door seal holder is fixed to the refrigerator door and adheres to it after the refrigerator door foams. The second door seal is installed in the groove on the outer ring of the door seal holder, and the first sealing strip is installed in the groove on the inner ring. The cabinet profile is installed on the refrigerator cabinet. After the refrigerator cabinet foams, the cabinet profile will adhere to the refrigerator cabinet. When the door is closed, the second door seal and the first sealing strip press against the refrigerator cabinet and the cabinet profile at the same time. Because the second door seal has a magnetic strip inside, it will be attracted to the galvanized and sprayed refrigerator cabinet. At this time, the second sealing strip will press against the cabinet profile. Through the double sealing of the second door seal and the first sealing strip, very little cold air leaks out of the refrigerator, increasing the product's heat preservation.
[0027] The beneficial effects of this utility model are: through the double sealing of the first sealing strip and the second door sealing strip, very little cold air leaks out of the refrigerator body, which increases the heat preservation of the product. The heat preservation time of the same product is increased by 25%, and the power consumption is reduced by about 15%. This allows the product to store a wider range of items and can maintain a constant temperature range for a long time, allowing for the storage of items with higher temperature requirements, such as medical medicines and high-end food ingredients.
