[0037] Door seals are commonly used to prevent the leakage of cold or hot air, achieving a leak-proof effect. For example, door seals in refrigeration equipment are used. In related art, refrigeration equipment includes a housing and a door. The door covers the opening of the housing, forming a straight gap between the housing and the door for air circulation. The door seal is designed to seal this straight gap between the housing and the door. However, if the housing or door deforms, a gap can easily form between the door seal and the housing or door, leading to cold air leakage, condensation, and increased energy consumption for the refrigeration equipment.

[0038] The first embodiment of the present invention provides a door sealing structure for sealing the gap between the door body 400 and the box body 500. Figures 1 to 3 As shown, the door sealing structure includes a door sealing body 100 and a fitting part 200, one of the door sealing body 100 and the fitting part 200 is arranged on the door body 400, and the other is arranged on the box body 500; one of the door sealing body 100 and the fitting part 200 is provided with a protrusion 110, and the other is provided with a recessed part 210, and the protrusion 110 cooperates with the recessed part 210 to seal the gap between the door body 400 and the box body 500; at least one of the protrusion 110 and the recessed part 210 is provided with a rib 300, and the rib 300 is located between the protrusion 110 and the recessed part 210.

[0039] The cooperation between the recessed portion 210 and the raised portion 110 allows the door seal body 100 and the mating component 200 to at least partially overlap and intersect, reducing the possibility of cold air passing between the door body 400 and the cabinet 500 and improving the sealing performance of the door seal structure. The door seal body 100 and the mating component 200 at least partially overlap and intersect, minimizing the possibility of gaps between the door seal body 100 and the mating component 200 due to local deformation of the cabinet 500 or the door body 400, thereby reducing the risk of cold or hot air leakage. Ribs 300 are provided between the recessed portion 210 and the raised portion 110 to limit the passage of cold or hot air between the seal body and the mating component 200, thereby improving the sealing performance.

[0040] By interlocking the recessed portion 210 and the raised portion 110, without adding other fixing structures, the firmness of the connection between the door seal body 100 and the fitting 200 can be improved, the adsorption effect of the door body 400 and the box body 500 can be improved, and the sealing performance can be improved.

[0041] The ribs 300 are disposed between the recessed portion 210 and the raised portion 110, increasing the path for gas to pass between the raised portion 110 and the recessed portion 210, thereby increasing resistance to the escape of cold or hot air and thereby improving the sealing performance. Generally, the ribs 300 are made of a soft material, such as polyvinyl chloride (PVC), thermoplastic elastomer (TPE), or thermoplastic polyurethane (TPU). This soft material allows the ribs 300 to deform to a certain extent. When the recessed portion 210 and the raised portion 110 are mated, the ribs 300 abut against at least one of the raised portion 110 and the recessed portion 210. Under pressure, the ribs 300 deform and fill the gap between the recessed portion 210 and the raised portion 110, forming an effective seal to prevent leakage or intrusion. Furthermore, the surfaces of the recessed portion 210 and the raised portion 110 may be uneven, and the soft material allows the ribs 300 to better adapt to the different shapes of the contact surfaces, achieving a better sealing effect.

[0042] At least one of the raised portion 110 and the recessed portion 210 is provided with a rib 300, that is, the rib 300 can be provided on the raised portion 110, or on the recessed portion 210, or the rib 300 can be provided on both the raised portion 110 and the recessed portion 210; when the raised portion 110 and the recessed portion 210 cooperate, the rib 300 is located between the recessed portion 210 and the raised portion 110 to reduce the gap between the raised portion 110 and the recessed portion 210; that is, by covering the door body 400 on the box body 500 and cooperating with the raised portion 110 and the recessed portion 210, the rib 300 can be located between the raised portion 110 and the recessed portion 210, without manually installing the rib 300 or adjusting the position of the rib 300, and the operation is simple.

[0043] One of the door seal body 100 and the matching piece 200 is arranged on the door body 400, and the other is arranged on the box body 500; the door seal body 100 can be arranged on the door body 400, and the matching piece 200 is arranged on the box body 500; or the door seal body 100 is arranged on the box body 500, and the matching piece 200 is arranged on the door body 400; the embodiment of the present utility model does not specifically limit the specific positions of the door seal body 100 and the matching piece 200.

[0044] It should be noted that the door seal body 100 can be fixedly connected to the door body 400 or the box body 500, or it can be integrally formed with the door body 400 or the box body 500; generally, the door seal body 100 is made of a soft material, such as polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic polyurethane elastomer (TPU), etc. The door seal body 100 made of a soft material can be compressed and expanded to better adapt to uneven installation surfaces, ensure tight closure at the joints, and thus provide a better sealing effect. The fitting 200 can be made of a hard material for easy processing and molding, or it can be made of a soft material, which is conducive to the sealing between the fitting 200 and the door seal body 100; the fitting 200 can be connected to the box body 500 or the door body 400, or the fitting 200 can be a part of the box body 500 or the door body 400, and the embodiment of the present utility model does not specifically limit this.

[0045] See also Figure 3 In some embodiments, the rib 300 includes a first rib 310 and a second rib 320, the first rib 310 is located at the raised portion 110, and the second rib 320 is located at the recessed portion 210. When the raised portion 110 and the recessed portion 210 cooperate, the first rib 310 located at the raised portion 110 is in close contact with the surface of the recessed portion 210 and the second rib 320 located at the recessed portion 210 is in close contact with the surface of the raised portion 110, further increasing the path for gas to pass between the raised portion 110 and the recessed portion 210, effectively reducing the probability of cold air or hot air leakage, and improving the sealing performance.

[0046] See also Figure 3 In some embodiments, the first rib 310 and the second rib 320 are staggered. On the one hand, the path for the gas to pass between the protrusion 110 and the recessed portion 210 can be extended to the maximum extent to improve the sealing performance. On the other hand, the overlap of the first rib 310 and the second rib 320 can be avoided, which may cause the protrusion 110 or the recessed portion 210 to be deformed due to local pressure.

[0047] See also Figure 3In some embodiments, a filling cavity 120 is formed inside the door seal body 100, and a filler 130 is provided inside the filling cavity 120. The filler 130 is at least partially made of thermal insulation material. Using thermal insulation material as the filler 130 to fill the door seal body 100 can minimize the transfer of heat through the door seal body 100, reduce the thermal conductivity of the door seal body 100, and improve the thermal insulation performance of the door seal structure. The filler 130 can fill the interior of the filling cavity 120 to occupy the space inside the filling cavity 120, thereby reducing the convection heat transfer point inside the filling cavity 120 and reducing the thermal conductivity. The filler 130 can be entirely or partially made of thermal insulation material. The thermal insulation material can include one or more of EPDM rubber foam, hollow fiber, and polyurethane closed-cell foam. The present invention does not specifically limit the thermal insulation material, as long as the thermal insulation material has thermal insulation performance.

[0048] See also Figure 3 In some embodiments, the door seal body 100 is provided with a protruding portion 140 to increase the width of the door seal body 100 in its extension direction to reduce the thermal conductivity of the door seal body 100.

[0049] See also Figure 3 In some embodiments, the filling cavity 120 is partially provided on the outer protrusion 140 so that the space of the filling cavity 120 is increased as much as possible, and the filling material is filled inside the filling cavity 120. By increasing the volume of the filling cavity 120, the amount of filling material inside the door sealing body 100 is increased, thereby improving the thermal insulation performance of the door sealing body 100.

[0050] It should be noted that, in this paper, the extending direction of the door seal body 100 is taken as the length direction of the door seal body 100 (eg Figure 2 a direction in the figure), when the door body 400 is in a closed state, the direction from the door body 400 to the box body 500 is the thickness direction of the door seal body 100 (such as Figure 4 b direction), that is, when the door seal body 100 is fixed on the door body 400, the thickness direction of the door body 400 is the thickness direction of the door seal body 100, and the width direction of the door seal body 100 (such as Figure 2 and Figure 4 The c direction in FIG is perpendicular to the length direction of the door seal body 100 and perpendicular to the thickness direction of the door seal body 100. The outer protrusion 140 is provided on the door seal body 100 along the width direction of the door seal body 100 to limit heat transfer between the door body 400 and the cabinet 500, thereby ensuring the thermal insulation effect of the door seal body 100.

[0051] See also Figure 3In some embodiments, the door seal body 100 has a mating surface 150 and a connecting surface 160. The mating surface 150 is adapted to mate with the mating component 200, while the connecting surface 160 is adapted to connect to the door body 400 or the housing 500. The width of the mating surface 150 is greater than the distance between the mating surface 150 and the connecting surface 160. By increasing the width of the mating surface 150, the contact area between the door seal body 100 and the mating component 200 is increased, thereby improving the sealing effect. The distance between the mating surface 150 and the connecting surface 160 is the minimum distance between the mating surface 150 and the connecting surface 160.

[0052] See also Figure 3 In some embodiments, the width of the mating surface 150 is greater than the width of the connecting surface 160. By increasing the width of the mating surface 150, the contact surface area between the door seal body 100 and the mating component 200 is increased, thereby improving the sealing effect.

[0053] See also Figure 4 In some embodiments, the door seal body 100 may be provided with an inverted cone 170. A corresponding groove 410 is provided on the door body 400. The inverted cone 170 engages with the groove 410 to achieve connection between the door body 400 and the door seal body 100. The inverted cone 170 has an inverted cone end 171 that engages within the groove 410. Two fins 172 extend along the sidewalls of the inverted cone end 171. The two fins 172 engage the inner sides of the notch in the groove 410, preventing the door seal body 100 from falling off the door body 400 and maintaining a secure connection between the door seal body 100 and the door body 400. A cavity 173 is defined within the inverted cone 170. When the door seal body 100 is installed or removed, the inverted cone 170 quickly returns to its original shape after being squeezed, preventing deformation and improving its reliability and durability. Of course, in other embodiments, the door seal body 100 may also be connected to the housing 500 via the inverted cone 170, and this is not a limitation of the present invention.

[0054] See also Figure 4 In some embodiments, the door seal body 100 may be provided with an extension strip 180, which is provided on the connecting surface 160. The extension strip 180 extends toward the door body 400 and abuts against the door body 400, thereby increasing the fitting surface between the door seal body 100 and the door body 400, reducing the leakage of cold air, achieving a compensatory sealing effect, and improving the sealing performance of the door seal body 100.

[0055] It is understood that when the raised portion 110 is provided on the door seal body 100, the mating surface 150 is located on the raised portion 110; and when the recessed portion 210 is provided on the door seal body 100, the mating surface 150 is located on the recessed portion 210. It should be noted that the width of the mating surface 150 refers to the dimension of the mating surface 150 in the width direction of the door seal body 100, and the width of the connecting surface 160 refers to the dimension of the connecting surface 160 in the width direction of the door seal body 100.

[0056] See also Figure 4 In some embodiments, a guide surface 111 is provided at the opening of the recessed portion 210, and the raised portion 110 slides into the recessed portion 210 through the guide surface 111. The guide surface 111 serves to guide the raised portion 110, thereby reducing the resistance between the door seal body 100 and the mating piece 200, reducing the risk of the door seal edge twisting, and allowing the door body 400 to open and close smoothly.

[0057] See also Figure 3 and Figure 4 In some embodiments, at least two ribs 300 are provided. Multiple ribs 300 can increase the resistance to cold air passing between the recessed portion 210 and the raised portion 110, thereby improving the sealing performance of the sealing structure. At least two ribs 300 are arranged on the guide surface 111. The ribs 300 can reduce the possibility of cold air intruding or overflowing from the opening of the recessed portion 210.

[0058] See also Figure 4 In some embodiments, the recessed portion 210 includes a bottom surface 112 and two guide surfaces 111. One end of the bottom surface 112 is connected to one of the guide surfaces 111, and the other end is connected to the other guide surface 111. The bottom surface 112 and the guide surfaces 111 can be connected by a curved surface to reduce blind spots in the cleaning of the recessed portion 210. Ribs 300 can also be provided on the bottom surface 112.

[0059] See also Figure 4 In some embodiments, the guide surface 111 is a curved surface. This surface can reduce friction between the protrusion 110 and the recess 210, facilitating easier docking between the protrusion 110 and the recess 210, ensuring accurate mating between the mating member 200 and the door seal body 100, and thereby improving the stability and accuracy of the door seal structure. Correspondingly, the mating surface 150 is a curved surface.

[0060] In some embodiments, the guide surface 111 is a plane to facilitate processing of the fitting 200. The guide surface 111 can be an inclined surface so that the cross section of the recessed portion 210 is trapezoidal in shape, reducing the risk of the door seal being twisted.

[0061] A second embodiment of the present invention provides a refrigeration device, which includes a box body 500, a door body 400 and a door sealing structure of any embodiment of the first aspect.

[0062] It can be understood that if the door seal structure has the beneficial effects of the above embodiments, then the refrigeration equipment will correspondingly have the beneficial effects of the above embodiments. Its specific implementation method can refer to the above embodiments, and this application will not go into details.

[0063] Refrigeration equipment includes but is not limited to refrigerators, freezers, etc.

[0064] Finally, it should be noted that the above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention.
