Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a sealing strip and refrigeration equipment. Background Art

[0002] With the continuous improvement of living standards, refrigeration equipment (refrigerators) have become an indispensable household appliance for most families, and people have increasingly higher requirements for the use of refrigeration equipment (refrigerators). The door and the cabinet of the refrigeration equipment (refrigerator) are connected by a magnetic strip inside the sealing strip and the metal plate outside the cabinet, isolating the interior of the refrigeration equipment from the outside world.

[0003] The sealing strips in the prior art refrigeration equipment (refrigerator) are as follows Figure 1 As shown, there are the following disadvantages: The common assembly structure of the door A01 and the sealing strip A02 of a current refrigeration appliance (refrigerator) is that the tongue of the sealing strip A02 engages with a slot (omega slot) in the door lining. There is a gap between the tongue and the slot (omega slot), and the tongue of the sealing strip is hollow. When the refrigeration appliance (refrigerator) is cooled, the tongue contracts, widening the gap and forming a cold leakage channel, causing cold leakage.

[0004] In summary, the sealing strips of refrigeration equipment in the prior art are prone to cold leakage. Utility Model Content

[0005] The embodiment of the present invention provides a sealing strip and a refrigeration device, so as to solve the problem that the sealing strip of the refrigeration device in the prior art is prone to cold leakage.

[0006] To achieve the above-mentioned purpose, the utility model provides a sealing strip connected to the inner lining of the door of the refrigeration equipment. The sealing strip includes at least two tongues arranged at intervals along the direction of cold air leakage. All of the tongues are solid structures, and the tongues are engaged with the inner lining of the door.

[0007] Furthermore, a sealing surface is formed between two adjacent latches, which abuts and seals against the inner lining of the door.

[0008] Furthermore, the sealing surface is a planar structure, and the plane where the sealing surface is located is perpendicular to the insertion direction of the tongue.

[0009] Furthermore, the sealing strip includes a magnetic colloid, which has a rubber material and a magnetic powder material; the magnetic colloid is used to abut and adsorb with the box of the refrigeration equipment, and the tongue is connected to the magnetic colloid.

[0010] Furthermore, a first air bag is provided inside the magnetic colloid.

[0011] Furthermore, the rubber material and the magnetic powder material in the magnetic colloid are evenly distributed.

[0012] Furthermore, the sealing strip further comprises a sealing portion, wherein the sealing portion is connected between the magnetic colloid and the latch tongue, and a plurality of second air bags are formed inside the sealing portion.

[0013] Furthermore, the sealing strip is provided with ventilation holes.

[0014] According to another aspect of the present invention, a refrigeration device is provided, comprising the above-mentioned sealing strip.

[0015] The sealing strip of this embodiment is equipped with multiple solid-structured latches, which extend the sealing surface. Cold air leakage is essentially blocked at the first latch, and cold air leakage is essentially eliminated from the second latch, thereby solving the problem of cold air leakage from the sealing strip. Multiple latches also ensure the secure assembly of the sealing strip. Furthermore, the solid-structure latches enhance the strength of the sealing strip. Even when exposed to cold, the sealing strip does not exhibit noticeable deformation, ensuring that the latches and the door lining maintain a basic sealed connection and engagement. This eliminates cold air leakage due to gaps created by the shrinkage of the latches, reduces cold air leakage at the latches, and improves sealing performance. The sealing strip is less likely to deform during long-term door opening and closing and under the action of gravity, ensuring reliable installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the present invention.

[0023] See also Figures 2 to 6As shown, according to an embodiment of the present invention, a sealing strip is provided, which is connected to the inner lining of the door of the refrigeration equipment. The sealing strip includes at least two tongues 10 spaced apart along the direction of cold air leakage. All of the tongues 10 are solid structures, and the tongues 10 are snap-connected with the inner lining of the door.

[0024] The sealing strip of this embodiment is provided with multiple solid-structured latches 10, which extend the sealing surface. The cold air leakage is essentially blocked at the first latch, and the cold air leakage from the second latch is essentially eliminated, thereby solving the problem of cold air leakage from the sealing strip. The multiple latches also ensure the secure assembly of the sealing strip. At the same time, the solid-structure latch enhances the strength of the sealing strip. Even when the sealing strip is exposed to cold, it does not exhibit noticeable deformation, ensuring that the latch and the inner lining of the door can always maintain a basic sealed connection and engagement. This eliminates cold air leakage due to gaps created by the shrinkage of the latch, reduces cold air leakage at the latch, and improves sealing performance. The sealing strip is not easily deformed during long-term door opening and closing and under the action of gravity, ensuring installation reliability.

[0025] Preferably, combined Figure 2 As shown, a sealing surface 11 is formed between two adjacent tongues 10 and is in sealing contact with the inner lining of the door.

[0026] The sealing surface 11 is located between two adjacent tabs 10. The sealing surface has a certain length and area. When engaged, the sealing surface abuts against the inner lining of the door and forms a seal. This further prevents cold air from leaking out of the tabs, further improving the sealing effect and solving the problem of cold air leakage. The shape of the sealing surface 11 can be adapted to the surface shape of the inner lining, such as a flat surface, a curved surface, or a curved surface.

[0027] In this embodiment, the sealing surface 11 is a planar structure, and the plane where the sealing surface 11 is located is perpendicular to the insertion direction of the tongue 10 .

[0028] The positional relationship between the sealing surface and the tongue can increase the path for cold air to leak outward, so that the leakage amount is gradually attenuated and reduced. The planar structure of the sealing surface is also conducive to sealing, which can effectively solve the problem of cold leakage.

[0029] like Figure 1 In the conventional sealing strip shown, due to the gap between the magnetic strip A03 of the sealing strip A02 and the rubber sleeve, cold air at the sealing strip's engaged position can easily transfer through the gap to the outside, causing condensation at the engaged position. The sealing strip is made of rubber, and the rubber sleeve can deform over time, causing the magnetic strip to sag, resulting in deformation of the sealing strip's twisted edge and a loose seal, which can lead to cold air leakage and condensation.

[0030] To solve the above problems of the prior art, in this embodiment, the sealing strip includes a magnetic colloid 20, which has a rubber material and a magnetic powder material; the magnetic colloid 20 is used to abut and adsorb with the box of the refrigeration equipment, and the tongue 10 is connected to the magnetic colloid 20.

[0031] Magnetic colloid 20 uses two independent injection gates to simultaneously inject rubber material and magnetic powder material into the sealing strip cross-section mold through dual runners, forming the mold simultaneously. This ensures that the cross-section of the sealing strip rubber sleeve and the magnetic powder are uniform after molding, forming a single piece. Magnetic colloid 20 enhances the strength of the sealing strip. Under long-term use and the action of gravity, the rubber sleeve is not easily deformed because the magnetic strip and rubber sleeve are integrated. Installation consistency is guaranteed, eliminating problems such as loose sealing and twisted edges caused by deformation of the sealing strip. The integrated magnetic colloid 20 eliminates a gap between the magnetic strip and the sealing strip, eliminating a cold leakage channel and reducing the generation of condensation.

[0032] See also Figure 3 The magnetic colloid 20 has a first airbag 21 inside. The sealing strip has a magnetic colloid. Under the same magnetic force, the magnetic colloid has a better attraction force. The sealing part of the door seal is designed to be a hollow structure. The hollow structure reduces mass and cost and is also beneficial to opening the door.

[0033] Preferably, the rubber material and the magnetic powder material are evenly distributed in the magnetic colloid 20. The even distribution of the rubber material and the magnetic powder material can facilitate adsorption on the box body, thereby preventing the occurrence of cold leakage due to insufficient adsorption of some sealing strips.

[0034] Combine Figure 2 and Figure 3 As shown, the sealing strip also includes a sealing portion 30 connected between the magnetic colloid 20 and the latch 10. Multiple second airbags 31 are formed within the sealing portion 30. The sealing portion is used for sealing. The wall thickness of the multiple second airbags 31 is the thinnest wall thickness (approximately 0.5 mm) for rubber molding, which facilitates deployment during door opening. The shape of the multiple second airbags 31 can be adjusted according to design requirements.

[0035] In an embodiment, the sealing strip is provided with ventilation holes. The ventilation holes are punched in the outer ribs of the sealing strip, and each complete sealing strip has at least one ventilation hole to prevent the formation of negative pressure.

[0036] The sealing strip structure is evenly compressed across the door and cabinet frame, with minimal compression. Through its hollow structure (airbag), thinner wall thickness, minimal compression, and air holes, the sealing strip avoids the drawback of excessive opening force in refrigeration equipment (such as refrigerators).

[0037] The utility model provides an embodiment of a refrigeration device, which comprises the above-mentioned sealing strip.
