Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a multi-layer heat-insulating refrigerator door sealing device and a refrigerator thereof. Background Art

[0002] As a common household appliance, refrigerators have many benefits, such as preserving food, storing a variety of ingredients, reducing food waste, and providing beverage storage. Refrigerators play an important role in family life, providing us with convenience, hygiene, economy and other benefits. In the era of advocating energy conservation, as every household has an appliance, it is very important to achieve energy conservation and emission reduction.

[0003] The door seal of a refrigerator door is an important part that ensures that the refrigerator maintains a cold temperature and prevents air loss. The door seal ensures the quality of the contents inside the refrigerator by ensuring that the temperature inside the refrigerator is constant. If the door seal is damaged or aged, it may cause cold air to leak, affecting the refrigerator's cooling effect. If the temperature inside the refrigerator cannot be maintained, the refrigerator needs to be cooled frequently, consuming too much energy. The door seal is usually made of rubber or silicone and is attached to the edge of the refrigerator door. It is generally necessary to check it regularly to see if it is intact and replace it when necessary.

[0004] The patent "Refrigerator Door Seal" (publication number CN104315788A, hereinafter referred to as prior art 1) discloses a door seal for a refrigerator door. Prior art 1 sets two elliptical door seal bases, and a cavity is provided inside the door seal base. The force caused by the contact between the refrigerator door and the cabinet is offset by the extrusion between the cavity and the outer surface. The setting of prior art 1 can have a certain buffering effect on the door seal base, but the two parts that collide and contact are the door seal body itself. When the door seal body is damaged due to collision, it can no longer be sealed. In addition, the elliptical setting of prior art 1 makes its two sides present inwardly convex arcs, so that its contact with the cabinet is point contact, and its sealing effect after contact is not good.

[0026] Example 1

[0027] See also Figure 1The embodiment of the utility model provides a multi-layer heat-insulating refrigerator door sealing device, including a mounting part and an adsorption part and a support part arranged between the mounting part and the adsorption part. The traditional door sealing device 13 is only provided with a mounting part and an adsorption part. After a long time of use, it will be damaged due to the collision and extrusion between the refrigerator door 12 and the box body 11. By providing a support part as the middle part between the mounting part and the adsorption part, the damage caused by the collision and extrusion is alleviated by the support part, and a large amount of external force is absorbed by the support part. The door sealing device 13 is made of soft PVC material as a whole. Soft PVC is a material formed by adding a large amount of plasticizer, a sufficient amount of stabilizer and other additives to PVC resin, and then extruding. It has good insulation and softness. Its surface can form a good sealing surface, so it is used for sealing the refrigerator. This material can effectively prevent the door sealing device 13 from becoming hard and elastic due to being in a low temperature environment for a long time, thereby improving the life and use performance of the door sealing device 13, so that the door sealing device 13 can be reset even in a sub-zero temperature environment. The mounting part, the adsorption part and the support part are integrated. The mounting portion, the adsorption portion and the supporting portion are integrated into one unit.

[0028] See also Figure 1 , Figure 2 or Figure 3 , the mounting portion is provided with an extrusion cavity 21, and the two sides of the mounting portion are contracted into the extrusion cavity 21 by extrusion. The mounting portion is used to install the door sealing device 13 and the refrigerator door 12. When the door gap device is installed, one end of the mounting portion is directed toward the installation position on the refrigerator door 12, and the door gap device is pressed inward toward the installation position on the refrigerator door 12. When the two sides of the mounting portion are pressed, the two sides of the mounting portion contract toward the internal extrusion cavity 21. When the mounting portion enters the installation position of the refrigerator door 12, the two sides of the mounting portion recover to their original shape after losing the pressure from the outside.

[0029] See also Figure 1 or Figure 3, the adsorption part is provided with a first insulation cavity 31 and a second insulation cavity 32; the second insulation cavity 32 is provided with an adsorption component. Compared with the temperature inside the refrigerator and outside the refrigerator, the temperature outside the refrigerator is generally higher. If the temperature outside the refrigerator enters the refrigerator and lowers the temperature inside the refrigerator, the substances inside the refrigerator will be damaged. The adsorption part isolates the heat outside the refrigerator door 12 through the insulation cavity through the first insulation cavity 31 and the second insulation cavity 32. The first insulation cavity 31 is farther away from the outside of the refrigerator, and the second insulation cavity 32 is closer to the inside of the refrigerator. The second insulation cavity 32 is provided with an adsorption component, which is a magnetic component. The refrigerator door 12 is adsorbed to the box body 11 through the magnetic component provided in the second insulation cavity 32. The outer surface of the adsorption part is an adsorption contact surface 33, and the adsorption contact surface 33 is adsorbed when it contacts the surface of the box body 11. After contact, the air inside the refrigerator is prevented from leaking out, and heat insulation is also performed by the magnetic component provided in the second insulation cavity 32. Generally, the magnetic component has poor thermal conductivity, so that the heat of the first insulation cavity 31 cannot be transferred to the inside of the refrigerator through the first insulation cavity 31. And through the adsorption of the magnetic component, the sealing of the refrigerator door 12 and the box body 11 is completed. Generally, there is a suction force after the magnetic component is adsorbed to the box body 11. This suction force ensures the stability between the refrigerator door 12 and the box body 11 after closing, and ensures that the refrigerator door 12 and the box body 11 remain in a sealed state without the action of external forces. The adsorption part contacts and adsorbs the box body 11 of the refrigerator through the adsorption contact surface 33.

[0030] See also Figure 1 or Figure 2 , the two ends of the mounting portion are respectively a plug end 22 and a connection end 23. The plug end 22 is an end inserted into the mounting position of the refrigerator door 12. The connection end 23 is used to assist the plug end 22 in inserting into the mounting position of the refrigerator door 12. The connection end 23 is also used to connect the support portion. The connection end 23 of the mounting portion is provided with a receiving piece 51. The air inside the refrigerator may flow outward from the gap existing at the mounting position of the refrigerator door 12, and the mounting portion is isolated from the mounting position of the refrigerator door 12 by the receiving piece 51. When the mounting portion is installed at the mounting position of the refrigerator door 12, the surface of the receiving piece 51 contacts the surface of the mounting position of the refrigerator door 12. The receiving piece 51 is arranged in an arc shape. When the receiving piece 51 contacts the mounting position of the refrigerator door 12, the receiving piece 51 will be squeezed and contact the mounting position of the refrigerator door 12 in a surface, blocking the path of air circulation inside the refrigerator.

[0031] See also Figure 2, the support part connects the mounting part and the adsorption part through the first support wall 41 and the second support wall 42 arranged on both sides; one end of the first support wall 41 and the second support wall 42 is connected to the surface of the receiving piece 51, and the other end is connected to the bottom surface of the adsorption part; the support part forms a support cavity 43 between the first support wall 41 and the second support wall 42. Generally, when the refrigerator door 12 is closed, it is usually subjected to a large force, so that the mounting part and the adsorption part are in direct hard contact. After many times, cracks will be generated, which will reduce the working quality or damage the door sealing device 13. By arranging the first support wall 41 and the second support wall 42 on both sides, the force of closing the refrigerator door 12 is unloaded through the first support wall 41 and the second support wall 42, so that the mounting part and the adsorption part cannot contact. The first support wall 41 and the second support wall 42 will bend inward or outward. Furthermore, a support column 44 is also provided in the support cavity 43, and the support column 44 is arranged in a "Y" shape. When the support cavity 43 is compressed inwardly by pressure, it is first supported by the first support wall 41 and the second support wall 42, and when the interior is compressed, it is supported by the support column 44. The inner wall of the top of the support cavity 43 is supported by one end of the bifurcated support column 44, thereby reducing the external force on it and extending its service life.

[0032] See also Figure 3 , a heat-insulating sheet 52 is also provided on one side of the receiving sheet 51; one end of the heat-insulating sheet 52 is connected to the receiving sheet 51; the heat-insulating sheet 52 is extended in the direction of the adsorption contact surface 33. Furthermore, since the door gap device has many wrinkles, a lot of dirt may accumulate. In order to avoid the accumulation of dirt outside the refrigerator and facilitate cleaning, a flat plate-shaped heat-insulating sheet 52 is provided. The setting of the heat-insulating sheet 52 not only isolates the external dirt, but also indirectly reduces the probability of external air entering the refrigerator. After the refrigerator door 12 is closed, the heat-insulating sheet 52 contacts the box body 11 to isolate the external air. A connecting sheet 53 is provided on the outer surface of the side of the first heat-insulating cavity 31; the connecting sheet 53 is connected to the inner surface of the heat-insulating sheet 52. Through the setting of the connecting sheet 53, the heat-insulating sheet 52 is installed more firmly. And a heat-insulating cavity is formed, so that the heat outside cannot be transferred.

[0033] See also Figure 2 After the heat insulation sheet 52 is connected to the connecting sheet 53, a third heat insulation cavity 54 is formed inside the first supporting wall 41. The end surface of the heat insulation sheet 52 close to the adsorption contact surface 33 is flush with the adsorption contact surface 33; after the adsorption contact surface 33 contacts and adsorbs the refrigerator body 11, a fourth heat insulation cavity 55 is formed between the heat insulation sheet 52 and the connecting sheet 53; the third heat insulation cavity 54 and the fourth heat insulation cavity 55 are arranged adjacent to each other.

[0034] The cross section of the plug-in end 22 of the installation part is set in an acute triangle; the cross section of the connecting end 23 is set in a rectangular shape. The installation part is set in a triangle, so that it is easier to insert into the installation position of the refrigerator door 12. The plug-in end 22 forms a clamping surface 221 on the side that is combined with the connecting end 23 after the combination. Through the clamping surface 221, the door sealing device 13 is clamped inside the installation position of the refrigerator door 12, and it cannot be taken out at will. The connecting end 23 is provided with a first clamping piece 231 and a second clamping piece 232 on both sides respectively; the first clamping piece 231 and the second clamping piece 232 are set at a preset angle with the connecting end 23; the preset angle is an acute angle. Through the angle setting of the first clamping piece 231 and the second clamping piece 232 of the connecting end 23, it is easier to help the entire installation part enter the installation position of the installation door, and it also helps the installation part to require a greater external force when it is separated from the installation door.

[0035] Example 2

[0036] See also Figure 1 and Figure 2 The embodiment of the utility model provides a refrigerator, comprising a box body 11 and a refrigerator door 12; the box body 11 is hollowed out to form a storage cavity 111; the refrigerator door 12 is hinged to the box body 11; the refrigerator door 12 is in an open or closed state with the storage cavity 111 of the box body 11 through the hinged connection with the box body 11. The door sealing device 13 is connected to the refrigerator door 12 of the refrigerator, and the door sealing device 13 and the refrigerator door 12 are sealed. The inner side of the refrigerator door 12 is provided with a mounting groove, and the mounting groove is adaptively arranged with the mounting portion. The multi-layer heat-insulating refrigerator door 12 sealing device is combined with the mounting groove of the refrigerator door 12 through the mounting portion; when the refrigerator door 12 and the box body 11 are in a closed state, the adsorption contact surface 33 is adsorbed with the box body 11. When the door sealing device 13 is clamped with the mounting groove, the position inside the mounting groove is clamped by the clamping surface 221 and the first clamping piece 231 and the second clamping piece 232. The first engaging piece 231 and the second engaging piece 232 act like a barb, so that the door sealing device 13 is not easy to fall off.
