Description

Technical Field

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

[0002] Some refrigeration equipment (such as refrigerators and freezers) use double or multi-layer vacuum glass as their doors to achieve excellent insulation. However, cold air leaks easily form at the junction of the edge of the vacuum glass and the door frame. Specifically, when the door is closed, there may be tiny gaps or assembly gaps where the vacuum glass meets the door frame, allowing cold air to escape through these gaps, affecting the door's insulation performance. This cold air leakage also requires the refrigeration equipment to run continuously to maintain the internal temperature, resulting in increased energy consumption and decreased efficiency. This not only increases user costs but can also shorten the equipment's lifespan.

[0003] In addition, as the cold air leaks out, the surface temperature of the door drops, which may cause frost or condensation on the outer surface of the door, further affecting the appearance of the door and the user experience. Summary of the Invention

DETAILED DESCRIPTION

[0032] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0033] It should be understood that the terms used herein, such as "upper," "above," "lower," and "below," etc., indicating spatial relative positions, are used for ease of explanation to describe the relationship of one element or feature relative to another element or feature as shown in the accompanying drawings. Spatially relative terms may be intended to encompass different orientations of the device in use or operation other than the orientation shown in the drawings.

[0034] An embodiment of the present invention provides a refrigeration device 100 with a door body that can achieve better thermal insulation performance, solves the problems of cold leakage and loose sealing at the connection between the door body and the cabinet, and improves the thermal insulation effect and service life of the refrigeration device 100.

[0035] The refrigeration device 100 of this embodiment may be a refrigerator, a freezer, a wine cabinet, a refrigerated cabinet, etc. The following description will be made using the refrigeration device 100 being a freezer as an example, particularly a vertical freezer.

[0036] The refrigerator includes a cabinet, a door and a refrigeration system, wherein the refrigeration system includes a compressor, a condenser, a capillary tube, an evaporator, a refrigeration pipeline, etc. The cabinet includes an inner liner wall 200 enclosing a refrigeration compartment 300, and the door closes the refrigeration compartment 300; the refrigeration compartment 300 may include a refrigeration compartment, a freezer compartment, a temperature-variable compartment, etc.

[0037] The door body of this embodiment is as follows Figure 1 and 2As shown, the vacuum glass 10 includes a vacuum glass 10 and a door frame 20. The vacuum glass 10 includes an inner glass 110 and an outer glass 120. Connecting material is provided around the edges of the inner glass 110 and the outer glass 120, and a vacuum layer 130 is provided between the inner glass 110 and the outer glass 120. The door frame 20 surrounds the vacuum glass 10, and the door body is connected to the cabinet through the door frame 20. The inner glass 110 is the glass closer to the interior of the refrigeration equipment 100, and the outer glass 120 is the glass closer to the exterior of the refrigeration equipment 100.

[0038] To clearly illustrate the positions and directions described in this embodiment, using an upright freezer as an example, this embodiment defines up and down with reference to the direction of gravity, with the direction of gravity being down and the direction opposite to gravity being up. When a user operates items within the refrigerator, the user stands in front of the refrigerator, with the direction opposite to gravity being the back. The left and right sides of the planes corresponding to front, back, and top are respectively defined. Thus, when the user opens the door, it opens forward, with the inner glass 110 positioned behind the outer glass 120. The door frame 20 includes four side frames: top, bottom, left, and right. When the door is closed, the vacuum glass 10 extends along the plane corresponding to the top, bottom, left, and right sides.

[0039] The inner glass 110 and / or the outer glass 120 of this embodiment includes a main body 11 and a bending portion 12. The planes of the main body 11 and the bending portion 12 are not coplanar. Figure 3 、 7 , 9, 10. The door frame 20 includes a receiving groove 221, and the bent portion 12 is inserted into the receiving groove 221. Figure 3 、 5 , 7, 10. By designing a bent portion 12 on the vacuum glass 10 and embedding the bent portion 12 into the receiving groove 221 of the door frame 20, the sealing performance between the door body and the door frame 20 is enhanced.

[0040] Specifically, the inner glass 110 may be provided with a bending portion 12, or the outer glass 120 may be provided with a bending portion 12, or both the inner glass 110 and the outer glass 120 may be provided with a bending portion 12, wherein: Figures 2 to 9 The inner glass 110 is shown to have a bent portion 12. Figure 10 As shown, the outer glass 120 is provided with a bent portion 12 .

[0041] When the inner glass 110 includes the bending portion 12 , the bending portion 12 is bent toward a side away from the outer glass 120 ;

[0042] When the outer glass 120 includes the bending portion 12 , the bending portion 12 is bent toward the side facing the inner glass 110 .

[0043] By defining the bending direction in this way, the bent portion 12 of the glass edge can more effectively fit into the receiving groove 221 of the door frame 20, avoiding gaps or mismatched bending angles at the glass edge, thereby further improving the sealing effect of the glass edge. Overall, the rational design of the bending direction makes the structural fit between the glass and the door frame 20 more stable and reliable.

[0044] The bent portion 12 of the glass edge is fitted into the accommodating groove 221 of the door frame 20. On the one hand, by increasing the contact area and the complex geometric shape, the leakage path of cold air from the inside of the vacuum glass 10 to the outside of the door body is effectively extended, preventing the cold air from directly diffusing to the outside from the connection between the door body and the door frame 20. The introduction of the bent portion 12 not only increases the contact area between the vacuum glass 10 and the door frame 20, but also makes the leakage path of cold air at the bent portion 12 more complicated.

[0045] On the other hand, the bent portion 12 is inserted into the receiving groove 221 of the door frame 20, so that the glass is fixed in the door frame 20 more firmly. The structural matching between the bent portion 12 and the receiving groove 221 can provide better tight connection, significantly reducing the poor sealing phenomenon caused by sagging of the door body or long-term use, forming a more stable assembly structure, enhancing the assembly strength of the door body and the box body, extending the service life of the product, and significantly improving the thermal insulation effect of the refrigeration equipment 100.

[0046] Preferably, if Figure 8 and 9 As shown, the main body 11 is rectangular, with a bend 12 on each of its four sides. Receiving grooves 221 are also provided on all four sides of the door frame 20. This allows the door to be tightly sealed on all sides via the bends 12 and the receiving grooves 221 of the door frame 20, creating a comprehensive seal that effectively prevents cold air from leaking from all four edges. Compared to traditional designs, this solution improves the overall sealing performance of the door through four-sided sealing, hindering any attempt by cold air to escape from any side, thereby enhancing the door's thermal insulation performance.

[0047] like Figure 3 、 5 As shown in Figures 7 and 9, the plane of the main body 11 is perpendicular to the plane of the bent portion 12, which bends toward the refrigeration compartment 300. This design of the bent portion 12 aligns with the direction of the refrigeration compartment 300, creating a "folded" structure for the cooling leakage path, further extending the leakage path and thus reducing the chance of leakage. Furthermore, this sealing method minimizes the increase in the thickness of the door frame 20, by positioning the accommodating groove 221 rearward rather than forward, occupying space in front of the refrigerator.

[0048] Furthermore, if Figure 7As shown, a heat insulating filling layer 210 is provided in the inner wall 200, and the heat insulating filling layer 210 can effectively prevent cold air from diffusing outward from the inner wall 200. The heat insulating filling layer 210 is generally a material such as a foam layer or a vacuum insulation board.

[0049] In the projection direction of the plane where the main body 11 is located, the distance from the side of the heat-insulating filling layer 210 close to the refrigeration compartment 300 to the refrigeration compartment 300 is smaller than the distance from the side of the vacuum glass 10 away from the refrigeration compartment 300 to the refrigeration compartment 300. Figure 7 The first boundary line L1 in FIG is located at the side of the heat insulation filling layer 210 close to the refrigeration compartment 300. Figure 7 As can be seen from the figure, the extension direction of the first boundary line L1 is aligned with the thermal insulation filling layer 210, rather than extending to the refrigeration compartment 300, that is, the second boundary line L2 is located between the first boundary line L1 and the refrigeration compartment 300.

[0050] By adjusting the positional relationship between the vacuum glass 10 and the thermal insulation filling layer 210, it is ensured that most of the cold energy will not be lost from the right side of the first boundary line L1. The cold energy is locked inside the vacuum glass 10 and the second boundary line L2, reducing the cold energy loss between the first boundary line L1 and the thermal insulation filling layer 210, preventing condensation on the outer surface at the cold leakage position, and improving the overall performance.

[0051] Furthermore, the door body includes a door panel 30 and a heating element. The door panel 30 is arranged on a side of the vacuum glass 10 away from the refrigeration compartment 300, and a heating element is arranged between the door frame 20 and the door panel 30. Figure 5 and 7 As shown, a heating element is provided at the location of heating groove 211. The heating element is a heating wire that generates appropriate heat to prevent the cold air from condensing into frost or forming water droplets on the outer surface of the door. This structural design is particularly suitable for environments with high humidity or large temperature differences. It can keep the door surface dry and clean during use of the refrigeration device 100, thereby avoiding the degradation of thermal insulation performance and poor user experience caused by frost.

[0052] The heating elements are arranged at the edges around the door panel 30 to ensure that the door body can prevent cold air from condensing into frost or forming water droplets on the outer surface of the door body at the four edge positions. Since the four edge positions are protected, condensation will not occur inside the door panel 30, thereby improving the overall anti-frost and anti-condensation effect.

[0053] like Figure 5 and 7As shown, the door frame 20 includes an outer frame 21 and an inner frame 22. The thermal conductivity of the inner frame 22 is lower than that of the outer frame 21, and the inner frame 22 forms a receiving groove 221. The inner frame 22 can be made of PVC, while the outer frame 21 can be made of aluminum alloy. If the aluminum alloy is connected to the vacuum glass 10, a large amount of cooling energy will be lost. The design of this embodiment can form an effective "heat insulation layer" inside the door body. The inner frame 22 reduces the outward diffusion of cooling energy and prevents cooling energy from leaking to the outside through conduction of the door frame 20 material, further improving the thermal insulation performance of the refrigeration device 100.

[0054] like Figure 3 、 5 As shown in Figures 7 and 10, the door frame 20 includes a sealing sheet 222 disposed in the accommodating groove 221. The sealing sheet 222 extends along the extension direction of the door frame 20, and the sealing sheet 222 abuts against the bent portion 12. The sealing sheet 222 can abut against the bent portion 12 of the glass during the door assembly process, forming an "embedded" sealing structure. The function of the sealing sheet 222 is not only to improve the sealing performance of the door body, but also to buffer the contact pressure between the door body and the door frame 20, so that when the door body is subjected to external force or temperature changes, it can maintain good elastic recovery ability, effectively preventing sealing failure caused by material expansion and contraction.

[0055] Continue as Figure 3 、 5 As shown in Figures 7 and 10, the door frame 20 includes a supporting rib 223 disposed in the receiving groove 221. The supporting rib 223 is disposed opposite to the sealing sheet 222. The hardness of the supporting rib 223 is greater than that of the sealing sheet 222. After the bent portion 12 is inserted into the receiving groove 221, the supporting rib 223 presses against the bent portion 12, causing the sealing sheet 222 to deform. After the bent portion 12 is inserted into the receiving groove 221, the supporting rib 223 can exert a supporting force on the bent portion 12 and force the sealing sheet 222 to deform, thereby making the bent portion 12 more tightly embedded in the receiving groove 221. This structural design not only enhances the fixing effect of the glass and the door frame 20, but also further improves the sealing performance of the door body, and can effectively prevent the cold from leaking through the connection between the glass and the door frame 20.

[0056] Compared with the prior art, this embodiment has the following beneficial effects:

[0057] (1) By providing a bent portion 12 on the vacuum glass 10 of the door body and inserting it into the receiving groove 221 of the door frame 20, the problem of cold leakage existing in the prior art is effectively improved. The bent portion 12 on the edge of the glass and the receiving groove 221 of the door frame 20 are interlocked with each other. On the one hand, by increasing the contact area and the complex geometric shape, the path of cold leakage is extended, preventing cold air from directly diffusing from the connection between the door body and the door frame 20 to the outside world; on the other hand, the structural matching of the bent portion 12 and the receiving groove 221 can provide a better tight fit, significantly reducing the poor sealing phenomenon caused by sagging of the door body or long-term use, and forming a more stable assembly structure.

[0058] (2) The cooperation between the vacuum glass 10 and the door frame 20 adopts a design of a sealing sheet 222 and a supporting ridge 223 at the bending portion 12. This combination forms a multiple sealing structure between the door body and the door frame 20, which can maintain a stable sealing effect even after long-term use.

[0059] (3) Compared with the use of thickened insulation materials, this embodiment does not require additional thickness or weight of the door body, thereby reducing the overall weight of the door body while ensuring thermal insulation performance, thereby reducing the risk of door sagging.

[0060] In summary, the structural design of the bending portion 12 and the accommodating groove 221 of the door frame 20 reduces the leakage of cold air, improves the thermal insulation effect of the refrigeration equipment 100, and makes the internal temperature of the refrigeration equipment 100 more stable, thereby reducing the operating frequency of the compressor, significantly improving the energy efficiency of the equipment, reducing energy consumption costs, and extending the service life of the equipment. It has important practical value and broad application prospects.
