[0033] In order to further understand the purpose, structure, features and functions of the present application, the embodiments are described in detail as follows.

[0034] In order to solve the problem of the joint and the tight sealing of the assembled gasket of the refrigeration device 100, the present application provides a refrigeration device 100, which comprises a box body 1 and a door body 2 connected to the box body 1. The box body 1 is provided with a first door seal 3 at the opening edge, and the door body 2 is provided with a second door seal 4 matched with the first door seal 3 at the periphery. When the door body 2 closes the opening of the box body 1, at least a part of the first door seal 3 protrudes outside the periphery of the second door seal 4.

[0035] The first door seal 3 is arranged at the opening edge of the box body 1 and is made of soft and durable material, such as silica gel or rubber. Its shape and size need to be closely matched with the opening edge of the box body 1,

[0036] The second door seal 4 is arranged on the periphery of the door body 2 according to the shape and size of the door body 2;

[0037] The second door seal 4 is matched with the first door seal 3 to ensure that a good nesting or pressing effect can be formed with the second door seal 4 when the door body 2 is closed, and at least a part of the first door seal 3 protrudes outside the periphery of the second door seal 4. Specifically, a certain protruding or extending part is designed on the periphery of the first door seal 3 to realize the visual effect of layering.

[0038] The first door seal 3 has a concave first arc surface 31, and the second door seal 4 has a convex second arc surface 41, and the first arc surface 31 is matched with the second arc surface 41.

[0039] The surface of the first door seal 3 in contact with the second door seal 4 is designed as a concave first arc surface 31;

[0040] The surface of the second door seal 4 in contact with the first door seal 3 is designed as a convex second arc surface 41 matched with the first arc surface 31;

[0041] When the door body 2 closes the opening of the cabinet 1, the concave first arc surface of the first door seal 3 and the convex second arc surface of the second door seal 4 are matched with each other to form a close contact. The contact and matching of the concave first arc surface 31 and the convex second arc surface 41 help to reduce the gap at the joint and improve the durability and stability of the door seal.

[0042] The first door seal 3 further comprises a third arc surface 32 connected with the first arc surface 31 and convex outward, and the third arc surface 32 is away from the opening of the cabinet 1 relative to the first arc surface 31.

[0043] The third arc surface 32 is connected with the first arc surface 31 and convex outward, and the third arc surface 32 is further away from the opening of the cabinet 1 relative to the first arc surface 31, that is, the third arc surface 32 is arranged on the outer peripheral edge of the first arc surface 31.

[0044] When the door body 2 is closed, the concave first arc surface 31 of the first door seal 3 and the convex second arc surface 41 of the second door seal 4 are nested with each other to form a close primary seal. At the same time, the convex third arc surface 32 of the first door seal 3 protrudes on the outer peripheral edge of the second door seal 4 to form a visual layering effect. At the same time, due to the close contact between the first arc surface 31 and the second arc surface 41, an effective sealing effect is realized, the cold air leakage is reduced, the energy consumption is reduced, and the heat preservation effect is improved.

[0045] The second arc surface 41 is provided with a sealing strip 43, and the sealing strip 43 has a fourth arc surface 432 matched with the first arc surface 31 and convex outward.

[0046] When the door body 2 closes the cabinet 1, the second convex arc surface 41 preliminarily fits the first concave arc surface 31, the fourth arc surface 432 of the sealing strip 43 closely contacts the first arc surface 31 of the first door seal 3, forming a continuous sealing line, effectively preventing cold air leakage, and improving the heat preservation effect of the refrigeration device 100.

[0047] In an optional embodiment, the first door seal 3 is around the opening edge of the cabinet 1, the second door seal 4 is around the edge of the door body 2, and the sealing strip 43 is buckled on the second arc surface 41 of the second door seal 4, that is, the sealing strip 43 and the second door seal 4 are both around the edge of the door body 2, to ensure the sealing property of the first door seal 3 and the second door seal 4.

[0048] Of course, the fixing mode of the sealing strip 43 and the second door seal 4 can be selected from buckling, bonding, screwing or other fixing modes, so that the sealing strip 43 is stably connected to the second arc surface 41 of the second door seal 4.

[0049] The fourth arc surface 432 includes at least one sealing protrusion 431 extending along the length direction of the sealing strip 43, and the sealing protrusion 431 abuts against the first arc surface 31.

[0050] The inner surface of the first door seal 3 and the second door seal 4 in contact is designed as a concave arc surface, that is, the first arc surface 31, and the outer surface of the second door seal 4 in contact with the first door seal 3 is designed as a convex arc surface, that is, the second arc surface 41, the convex second arc surface 41 preliminarily fits the concave first arc surface 31, the sealing strip 43 is connected to the second arc surface 41, the outer surface of the sealing strip 43 in contact with the first door seal 3 is designed as a convex fourth arc surface 432, the fourth arc surface 432 is designed as a sealing protrusion 431 protruding towards the first arc surface 31, specifically, when the door body 2 is closed, the sealing protrusion 431 abuts against the concave first arc surface 31 of the first door seal 3 in the height extension direction, forming a more close and stable sealing effect.

[0051] The sealing protrusion 431 extends along the length direction of the sealing strip 43 and is arranged, that is, the sealing protrusion 431 and the sealing strip 43 together are around the periphery of the door body 2.

[0052] When the door body 2 is closed, the sealing protrusion 431 of the sealing strip 43 closely contacts the first arc surface 31 of the first door seal 3 in a circle, forming a continuous and stable sealing line, and enhancing the sealing effect.

[0053] In an optional embodiment, the sealing strip 43 is made of soft, durable and high-elasticity materials, including but not limited to rubber materials, polyvinyl fluoride materials, silica gel materials or polyurethane materials, etc.

[0054] The second door seal 4 comprises a first part matched with the first door seal 3 and a second part connected with the first part, the second part protrudes in a direction away from the door body 2 to form a boss 44, and the lower end of the sealing strip 43 abuts against the boss 44 when the sealing strip 43 is deformed by extrusion.

[0055] Specifically, the first part of the second door seal 4 is matched with the first door seal 3 to ensure that the door seal can be tightly attached when closed to form an effective seal. That is, the first part comprises a second arc surface 41 protruding outward corresponding to the concave arc surface in the first door seal 3, so as to form a tight sealing line when the door body 2 is closed. The second part of the second door seal 4 is connected with the first part and protrudes in a direction away from the door body 2 to form a boss 44. The boss 44 is matched with the opening of the cabinet 1 when the door body 2 is closed, which not only enhances the sealing performance between the first door seal 3 and the second door seal 4, but also supports the lower end of the sealing strip 43 when the sealing strip 43 is deformed to make its position stable and prevent the sealing strip 43 from being tilted under pressure.

[0056] The second door seal 4 comprises at least two side door seals arranged segmentally along the periphery of the door body 2, and adjacent two side door seals are connected by an arc-shaped piece 42.

[0057] The second door seal 4 is arranged on the door body 2, and the second door seal 4 is segmented into at least two side door seals, i.e. arranged at the side positions required to be arranged on the door body 2. The segmented second door seal 4 can better adapt to the shape and size changes of the door body 2, and improve the flexibility of installation.

[0058] The adjacent two side door seals are connected by the arc-shaped piece 42, which not only ensures the integrity and stability of the door seal, but also enables the door seal to smoothly transition at the corner position, avoiding the influence of sharp corners on the sealing performance between the first door seal 3 and the second door seal 4. The arc-shaped piece 42 is matched with the concave first arc surface 31 of the first door seal 3 to ensure effective sealing performance at the corner position.

[0059] Similarly, the sealing strip 43 is arranged segmentally along the side door seal and matches the shape and size of the side door seal. At the corner position, the sealing strip 43 is also connected by the arc-shaped piece 42 to ensure that continuous sealing performance can be formed at the corner position.

[0060] In this application, the side door seal and the arc-shaped piece 42 can be formed by the same method or different methods in actual application, which is not limited in this application.

[0061] In optional embodiments, the side door seal can be formed by an extrusion method, and the arc-shaped member 42 can be formed by an injection molding method. Extrusion molding refers to a process in which plastic particles are softened by heating and then extruded by a screw of an extrusion machine. Injection molding refers to a process in which a plastic material is heated and melted, and then injected into a mold by an injection molding process, and a finished part is formed after cooling and solidification. In comparison, extrusion molding can continuously produce parts with certain length and strength. The arc-shaped member 42 is formed by injection molding, which can produce products with complex structures, facilitate connection in different ways at the corner, and facilitate expansion of the model.

[0062] In this application, the corner of the door body 2 can also be a circular arc-shaped corner to adapt to the first arc surface 31 of the first door seal 3.

[0063] The door body 2 includes a first side edge connected to the cabinet 1 by a hinge 6.

[0064] The first side edge of the door body 2 refers to the side edge connected to the cabinet 1. In this application, the first side edge of the door body 2 is connected to the cabinet 1 by the hinge 6, so that the door can be smoothly opened and closed.

[0065] The hinge 6 is connected by two connecting pieces through a shaft or a pin in the middle. One of the two connecting pieces is fixed on the cabinet 1, and the other is fixed on the first side edge of the door body 2. When the door is opened or closed, the two connecting pieces will rotate relative to the shaft or pin.

[0066] Compared with the traditional hinge connection, the overall structure of the hinge 6 is relatively flat and does not protrude out, which maintains the neatness and beauty of the appearance of the door body 2, avoids the adaptation between the first door seal 3 and the second door seal 4, and maintains the temperature in the cabinet 1 of the refrigeration device 100.

[0067] The door body 2 further includes a second side edge opposite to the first side edge, the second side edge is provided with a pressing member 5, the cabinet 1 is provided with a stop member 54 matched with the pressing member 5, the pressing member 5 includes a handle part 51, an extension part 52 and a stop part 53 connected in sequence from the outside of the door body 2 to the inside of the door body 2, and rotating the handle part 51 makes the stop part 53 engage or release the stop member 54.

[0068] The pressing member 5 is connected by the handle part 51, the extension part 52 and the stop part 53 in sequence, and extends from the outside to the inside of the door body 2. Specifically, the handle part 51 is the part for force operation, and has a shape convenient for gripping and rotating, the extension part 52 connects the handle part 51 and the stop part 53, and plays a role of force transmission and movement, and the stop part 53 cooperates with the stop member 54 on the cabinet 1, and when the pressing member 5 is rotated, the stop part 53 engages or releases the stop member 54.

[0069] The stopper 54 comprises a first section and a second section which are perpendicular to each other, one of the first section and the second section is connected to the cabinet 1, and the other section is provided with an opening. When the pressing member 5 is rotated into the opening, i.e. the pressing member 5 is buckled to the stopper 54, the door body 2 is tightly closed to the cabinet 1. When the pressing member 5 is rotated away from the opening, i.e. the pressing member 5 is released from the stopper 54, the door body 2 can easily open the cabinet 1.

[0070] The present application adopts the pressing member 5, which can realize the closing and opening of the door body 2 through simple rotating operation, and is very convenient. Meanwhile, the cooperation between the pressing member 5 and the stopper 54 can realize the tight closing between the door body 2 and the cabinet 1, and improve the sealing performance of the whole refrigeration device 100.

[0071] The handle section 51 is perpendicular to the extension section 52, and the extension section 52 is perpendicular to the stop section 53.

[0072] The handle section 51 is perpendicular or similar to the extension section 52, and the extension section 52 is perpendicular or similar to the stop section 53.

[0073] In an optional embodiment, the refrigeration device 100 is a refrigerator.

[0074] The present application relates to a refrigeration device 100, which comprises a cabinet 1 and a door body 2 connected to the cabinet 1. The opening edge of the cabinet 1 is provided with a first door seal 3, and the periphery of the door body 2 is provided with a second door seal 4 which is adapted to the first door seal 3. When the door body 2 is closed to the opening of the cabinet 1, at least a part of the first door seal 3 protrudes outside the second door seal 4. The present application forms the effect of the stacked door body 2 by providing the first door seal 3 at the opening of the cabinet 1 and the second door seal 4 at the periphery of the door body 2. When the door body 2 is in the closed state, the outer periphery of the first door seal 3 protrudes outside the outer periphery of the second door seal 4. The present application effectively reduces the joint of the stacked door seal assembly of the refrigeration device 100 through the mutual adaptation of the first door seal 3 and the second door seal 4, and improves the sealing effect between the door body 2 and the cabinet 1.
