Description
Technical Field
[0001] The utility model relates to the technical field of refrigerators, in particular to a novel silicone rubber door sealing component for refrigerators. Background Art
[0002] A freezer, also called a freezer, is a device that preserves food and other items at low temperatures. There are two types of freezers: home and commercial. Commercial freezers are used in restaurants, water bars, food processing, and supermarkets. In daily life, silicone rubber door seals are used for freezer doors. The freezer door seal is a freezer accessory used to seal between the freezer door and the box body. This door seal can also be used in disinfection cabinets, water dispensers, display cabinets, etc. for its sealing and insurance functions. High-quality sealing strips are made of high-quality rubber materials, with a thick and tough texture, excellent elasticity, corrosion resistance, and super strong adsorption, so that it fits tightly on the four inner sides of the freezer door and has very high sealing. A good sealing strip can effectively ensure that the cold air in the freezer is not easy to leak out, has excellent sealing performance, and has significant heat insulation and dustproof effects. What's more, by adding antibacterial agents to the sealing strips, the freezer can be mildew-proof and antibacterial.
[0003] However, when the current refrigerator is used in the summer season, there is a huge gap between the external ambient temperature and the internal temperature of the refrigerator. After opening the door, the cold air leaks out and the temperature inside and outside are different. The gas exchange causes the temperature inside to rise and the air becomes thinner. After closing the door, the inside and outside spaces are isolated. Since the temperature inside is low and the temperature outside is high, the gas pressure inside is lower than that outside. A pressure difference is formed, and the atmospheric pressure is tightly pressed on the door body. Using brute force to open the refrigerator door will cause the door seal to be pulled, deformed and damaged. Utility Model Content

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-7 The utility model provides a technical solution: a new silicone rubber door seal component for a refrigerator, comprising a main body 1, a silicone rubber door seal 2 is arranged in the main body 1, a mounting groove 21 is opened on one side of the silicone rubber door seal 2, the bottom of the mounting groove 21 is set as a rectangular hole 22, a semicircular hole 23 is opened on the upper side of the rectangular hole 22, a pressure relief piece 3 is installed in the mounting groove 21, a rectangular block 31 is installed in the pressure relief piece 3, straight baffles 32 are arranged at the edges of both ends of the rectangular block 31, and a through-out wall is opened on the rectangular block 31 A threaded groove 33 is provided, a semicircular block 4 is installed in the middle of the rectangular block 31, an arc-shaped baffle 41 is installed on the semicircular block 4, a through hole 42 is provided at one end of the semicircular block 4, a groove 43 is provided inside the semicircular block 4, and a filter screen 44 is installed at the bottom of the hollow, a button 5 is provided in the through hole 42, a sealing gasket 51 is installed at the bottom of the button 5, a limiting plate 52 is installed below the sealing gasket 51, a spring 53 is installed below the limiting plate 52, and a limiting column 54 runs through the middle of the spring 53.
[0025] The size of the rectangular hole 22 is larger than that of the rectangular block 31, and the size of the semicircular hole 23 is larger than that of the semicircular block 4, and the rectangular hole 22 and the semicircular hole 23 are connected. The mounting groove 21 and the outer contour of the pressure relief member 3 are matched, and the straight baffles 32 are symmetrically arranged, and the arc baffles 41 are symmetrically arranged at both ends of the semicircular block 4. The straight baffles 32 and the arc baffles 41 have the same height, and the straight baffles 32 and the arc baffles 41 are connected. The spacing between the straight baffles 32 is larger than the width of the mounting groove 21, and the interior of the semicircular block 4 is set to be hollow, and the button 5 and the through hole 42 are slidably connected. The mounting groove 21 should be installed on the outward side of the refrigerator door to meet normal usage habits. When the pressure relief piece 3 is installed in the mounting groove 21 in the silicone rubber door seal 2, both sides of the silicone rubber door seal 2 fall between the adjacent straight baffles 32 or arc baffles 41 in the pressure relief piece 3, and then a corresponding sealant or the like is used for sealing and connection. The hollow part of the semicircular block 4 is circular, so the filter screen 44 is a circular filter screen 44 and is installed at the other end of the hollow part.
[0026] The length of the sealing pad 51 is smaller than the groove 43, the size of the limiting plate 52 is larger than the groove 43, and the height of the sealing pad 51 is the same as that of the groove 43. In normal times, the spring 53 will push the limiting plate 52 upward to squeeze the sealing pad 51 in the groove 43 to achieve a sealing effect.
[0027] The top of the spring 53 is connected to the limit plate 52, and the bottom of the spring 53 is located on the filter 44. The filter 44 is not a simple mesh structure, and rings or beams are arranged inside it to play a supporting role, which is the same as supporting the spring 53 and the limit column 54.
[0028] The limiting column 54 is located in the middle of the filter screen 44, and there is a gap between the top of the limiting column 54 and the limiting plate 52. The limiting column 54 can prevent excessive pressing of the button 5, and prevent the button 5 from falling inside the semicircular block 4 and affecting the use.
[0029] Working principle: install the pressure relief piece 3 at the appropriate position of the refrigerator door through the threaded groove 33, and then turn the side of the silicone rubber door seal 2 with the installation groove 21 toward the pressure relief piece 3, so that the rectangular hole 22 falls on the rectangular block 31, and the semicircular hole 23 falls on the semicircular block 4. Since the distance between adjacent straight baffles 32 is greater than the width of the installation groove 21, the edge of the silicone rubber door seal 2 falls between the adjacent straight baffles 32, and then use the corresponding sealant for sealing. In summer, when the refrigerator door cannot be opened, press the button 5 inward with your finger, and the button 5 moves along the through hole 42, and the button 5 presses against the sealing pad 51 and the limit When the plate 52 moves and the spring 53 is deformed and compressed, the button 5 cannot be pressed any further when the limit plate 52 abuts against the limit column 54. At this time, the interior of the refrigerator is connected to the external environment through the pressure relief piece 3, so that the two are in a state of equilibrium with the same atmospheric pressure, and the door can be opened normally. Afterwards, the limit plate 52 is pushed upward under the action of the elastic force of the spring 53 to allow the sealing gasket 51 to fall into the groove 43, blocking the pressure relief piece 3 to prevent air leakage in the refrigerator. If the pressure difference between the inside and the outside is too large, the spring 53 will shrink without external force, allowing the sealing gasket 51 to leave the groove 43. This is also equivalent to active pressure relief, which also has the same effect.
