Description

Technical Field

[0001] The utility model belongs to the field of refrigerator sealing, and in particular relates to a multi-winged door sealing structure. Background Art

[0002] With the continuous upgrading of energy efficiency standards, reducing the energy consumption of refrigerators, as continuously running household appliances, has become a key improvement project for manufacturers. Optimizing the door seal structure is one of the important means to improve the sealing performance and energy efficiency of refrigerators.

[0003] Most refrigerator door seals currently available on the market use a traditional airbag and magnetic strip structure, achieving a seal between the door and the refrigerator body through the elastic deformation of the airbag and the suction force of the magnetic strip. This design can meet basic sealing requirements to a certain extent, but it still has many shortcomings in terms of energy efficiency and sealing performance.

[0004] First, traditional refrigerator door seals often rely on a single auxiliary airbag to achieve sealing. However, if the auxiliary airbag is too small, it may not fit tightly against the refrigerator body, resulting in a failed seal. If the auxiliary airbag is too large, it will cause scratches when closing the door and hinder the door from closing. Secondly, the airbag portion of traditional door seals is often relatively simple in structure, lacking sufficient deformation capacity and sealing structure, making it difficult to form an effective sealed chamber during the closing process of the refrigerator door. This leads to frequent gas exchange between the inside and outside of the refrigerator, affecting the insulation effect. In addition, due to poor sealing effect, the cold air inside the refrigerator can easily leak to the outside through the door seal, causing the compressor to frequently start to maintain the internal temperature, thereby increasing the refrigerator's energy consumption.

[0005] Therefore, developing a new door sealing structure to achieve energy saving and consumption reduction has important market value and social significance. Utility Model Content

[0006] The utility model provides a multi-winged door seal structure, which solves the problems of insufficient sealing performance, high energy consumption and poor adaptability of auxiliary airbags. By adding multiple flexible wings at key positions, the sealing performance is improved, the energy consumption is reduced, and the durability and adaptability are enhanced.

[0007] The technical solutions used in this utility model are as follows:

[0008] A multi-winged door seal structure is placed between the refrigerator body and the door body, comprising a crossbeam, an airbag portion, and a fastener, wherein the airbag portion is located on the crossbeam, and the fastener is located below the crossbeam, and further comprising:

[0009] Auxiliary wing, the auxiliary wing is arranged on one side of the airbag part, one side of the auxiliary wing is in contact with the door body, and when the door body is closed, the other side of the auxiliary wing contacts the box body to form multiple chambers.

[0010] An inner wing edge is provided on the inner wall of the airbag portion. When the door body is closed, the inner wing edge contacts the inner wall of the opposite side of the airbag portion.

[0011] Furthermore, the door body is provided with a groove, the latch is buckled in the groove, and further comprises a latch wing edge, the latch wing edge is provided on the latch, and the latch wing edge is interference fit with the groove.

[0012] Furthermore, the airbag portion includes a magnetic stripe bag and a first airbag, the first airbag is connected to the magnetic stripe bag edge by edge, the auxiliary wing edge is arranged on the side of the first airbag away from the magnetic stripe bag, and the inner wing edge is arranged on the inner wall of the first airbag.

[0013] Furthermore, the airbag portion also includes a second airbag and a third airbag, the second airbag is connected to the third airbag, the upper part of the second airbag is connected to the magnetic stripe bag and the bottom of the first airbag, and the upper part of the third airbag is connected to the bottom of the first airbag.

[0014] Furthermore, the airbag portion also includes a plurality of square chambers, which are arranged at the bottom of the second airbag, the plurality of square chambers and the third airbag are connected side by side, and the bottoms of the plurality of square chambers and the third airbag are connected to the crossbeam.

[0015] Furthermore, one side of the auxiliary wing is in the shape of an elongated strip, and the other side is provided with a plurality of synapses. The elongated side of the auxiliary wing is in contact with the door body. When the door body is closed, the tips of the plurality of synapses contact with the box body to form a plurality of chambers.

[0016] Furthermore, there are multiple inner wing edges, which are staggeredly arranged on two opposite sides of the first airbag. When the door body is closed, the tips of the inner wing edges contact the inner walls of the opposite sides, dividing the first airbag into multiple chambers.

[0017] Furthermore, a plurality of the snap-fit ​​wing edges are provided, and the plurality of the snap-fit ​​wing edges are arranged around the snap-fit ​​piece, and the plurality of the snap-fit ​​wing edges are interference-fitted with the inner wall of the groove to form a plurality of cavities.

[0019] The beneficial effects of the utility model are:

[0020] 1. This utility model features auxiliary wings on one side of the airbag. When the door is closed, the auxiliary wings fit snugly against the door and slot into the gap between the door and the refrigerator body, forming multiple chambers with the refrigerator body. This effectively blocks the exchange of air between the inside and outside of the refrigerator, significantly improving sealing performance. Furthermore, the flexible design of the auxiliary wings allows them to better adapt to slight deformations of the door during closing, ensuring an adequate seal while avoiding door rubbing and obstruction caused by an overly large airbag, thus enhancing the user's door opening and closing experience.

[0021] 2. The internal fins in this invention further enhance the thermal resistance of the door seal. When the door is closed, the internal fins contact the inner wall opposite the airbag, interlacing to form multiple closed chambers. These chambers increase the heat transfer path, improve thermal resistance, and effectively reduce the heat exchange rate between the inside and outside of the refrigerator, thereby reducing energy consumption and improving energy efficiency.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings.

[0028] like Figure 1-Figure 2As shown, this embodiment provides a multi-winged door seal structure, which is placed between the refrigerator body 1 and the door body 2. A groove 21 is provided on the door body 2 of the refrigerator. The multi-winged door seal structure includes an airbag part 3, a crossbeam 4 and a fastener 5. The bottom of the airbag part 3 is connected to the crossbeam 4, and the fastener 5 is located below the crossbeam 4. The fastener 5 is arrow-shaped as a whole, wherein the bottom of the arrow is connected to the crossbeam 4, and the two sides of the arrow are buckled in the above-mentioned groove 21 and abut against the inner wall of the groove 21 to fix the door seal structure on the door body 2.

[0029] The crossbeam 4 serves as a structure that supports the airbag portion 3 and the fastener 5, and is used to reinforce the rigidity of the door sealing structure so that the door sealing structure can withstand a larger longitudinal compression force. The airbag portion 3 is used to suppress or reduce the heat exchange between the inside of the refrigerator and the external environment, thereby achieving a sealing and heat-insulating effect. The fastener 5 is used to fix the sealing structure on the door body 2.

[0030] The airbag portion 3 is fixed to the door body 2 and moves synchronously along the closing trajectory of the door body 2. Specifically, Figure 1 and Figure 2 As shown, the airbag portion 3 includes a magnetic stripe bag 31, a first airbag 32, a second airbag 33, a first square chamber 34, a second square chamber 35 and a third airbag 36. The first airbag 32 is connected to the edge of the magnetic stripe bag 31, the upper part of the second airbag 33 is connected to the bottom of the magnetic stripe bag 31 and the first airbag 32, the upper part of the third airbag 36 is connected to the bottom of the first airbag 32, the second airbag 33 is connected to the third airbag 36, and a plurality of square chambers are provided at the bottom of the second airbag 33. Among the plurality of square chambers, the square chamber away from the magnetic stripe bag 31 is connected to the edge of the third airbag 36, and the bottoms of the plurality of square chambers and the third airbag 36 are all connected to the crossbeam 4. In this embodiment, there are two square chambers, namely the first square chamber 34 and the second square chamber 35, and the second square chamber 35 is connected to the third airbag 36.

[0031] The airbag part 3 will be deformed when it is subjected to the closing force of the door body 2 and the box body 1. Among them, the magnetic strip bag 31 has a built-in magnetic strip to enhance the adsorption force of the door body, ensuring that the door body 2 fits tightly with the box body 1 after closing. The first airbag 32 effectively alleviates the impact force when the door body 2 is closed through elastic deformation, achieving a smooth closing process. In addition, the first airbag 32 is arc-shaped on the side close to the door body 2, so that it can be compressed and deformed more smoothly during the closing process of the door body 2, reducing the contact gap between the door seal and the box body 1, improving the sealing effect, and ensuring the stability and energy saving of the internal environment of the refrigerator. In the cycle of closing and opening the door body 2, the second airbag 33 needs to withstand tensile and compressive deformation to ensure that the door sealing structure can conform to the door The body 2 moves to maintain a stable sealing effect. The deformation of the second airbag 33 fills the tiny gap between the door body 2 and the box body 1, further optimizing the sealing performance. The multiple square chambers arranged at the bottom of the second airbag 33 not only enhance the internal structural strength of the airbag part 3, but also make the airbag part 3 as a whole remain stable under external action. The third airbag 36 is designed to be close to the bladder surface of the door body 2, which can ensure that it fits closely with the bladder surface when the door body 2 is closed, reducing heat conduction and further consolidating the heat preservation ability of the refrigerator. The first square chamber 34, the second square chamber 35, the second airbag 33 and the third airbag 36 together constitute a plurality of independent isolation air chambers, which can effectively prevent the circulation of internal and external gases, improve the heat preservation effect of the refrigerator and reduce energy consumption.

[0032] Furthermore, in order to solve the problem that the auxiliary airbag is too small to be effectively sealed and too large to hinder the closing of the door body 2, as shown in FIG. Figure 1 and Figure 2 As shown, an auxiliary wing 6 is provided on the side of the first airbag 32 facing away from the magnetic stripe bag 31, replacing the auxiliary airbag to achieve a flexible seal. Specifically, the auxiliary wing 6 has a long strip on one side and multiple synapses on the other side. The long strip side of the auxiliary wing 6 fits in contact with the door body 2. When the door body 2 is closed, the auxiliary wing 6 will follow the closing trajectory and insert into the gap between the door body 2 and the box body 1. The tip of each synapse contacts the box body 1, forming multiple chambers, further blocking the exchange of internal and external gases, thereby achieving a more efficient sealing effect. At the same time, the flexible seal can better adapt to the slight deformation of the door body 2 during the closing process, maintaining stable sealing performance, especially for air leakage caused by deformation of the door body 2 or installation errors.

[0033] Furthermore, in order to avoid convection caused by temperature difference and reduce heat transfer, multiple inner wing edges 7 are staggered on the opposite sides of the inner wall of the first airbag 32. When the door body 2 is closed, the airbag part 3 is compressed and deformed by force, and the inner wing edges 7 are staggered and displaced with each other, dividing the first airbag 32 into multiple closed chambers, increasing the path and difficulty of heat transfer, improving the overall thermal resistance performance of the door sealing structure, and effectively reducing the heat exchange rate inside and outside the refrigerator.

[0034] Furthermore, in order to reduce heat transfer, a plurality of snap wings 8 are arranged around the snap member 5. The plurality of snap wings 8 are interference fit with the inner wall of the groove 21 on the door body 2 to form a plurality of chambers, which increases the thermal resistance on the heat transfer path, helps to reduce the loss of cold air inside the refrigerator to the external environment through the door sealing structure, thereby achieving the purpose of energy saving and consumption reduction; in addition, the snap wings 8 enhance the fixing effect of the door sealing structure on the door body 2, prevents loosening or falling off due to vibration or external force during use, and improves the stability and durability of the door sealing structure by increasing the contact area and friction.

[0035] The door seal structure provided in this embodiment is an integral part, and the crossbeam 4, the airbag portion 3, the snap-fitting member 5, the auxiliary wing edge 6, the inner wing edge 7 and the snap-fitting wing edge 8 are connected to each other.

[0036] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
