Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a refrigerator door and a refrigerator. Background Technology

[0002] To improve aesthetics, refrigerator door handles are typically recessed to conceal them. However, this design results in a smaller distance between the handle and the refrigerator interior, and a thinner insulation layer, leading to lower temperatures at the handle area. When there is a significant temperature difference between the inside and outside of the refrigerator, condensation can form on the handle, causing inconvenience to the user. To address this, related technologies have employed methods such as thickening the door and adding heating wires to the handle to prevent condensation. However, thickening the door increases cost and bulk, and restricts the opening angle, making it inconvenient for users. Adding heating wires increases energy consumption and requires complex wiring and layout. Utility Model Content

[0006] The refrigerator door body according to the first aspect of this utility model has at least the following beneficial effects: By connecting a heat-conducting component between the panel and the second wall of the handle, the heat of the panel can be directed to the second wall of the handle, thereby increasing the temperature of the handle, reducing the temperature difference between the handle and the outside of the refrigerator, and the heat-conducting component can make the temperature of the second wall more uniform, avoiding local overcooling of the second wall, thus effectively reducing the risk of condensation on the handle. At the same time, since the heat-conducting component is spaced apart from the first wall, heat transfer to the first wall is avoided, allowing the heat-conducting component to accurately guide the heat of the panel to the second wall, rather than the first wall, thereby further reducing the temperature difference between the second wall and the outside of the refrigerator, and reducing the risk of condensation.

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationships based on the directional or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, connecting, assembling, and cooperating should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] It's easy to understand that, as a common refrigeration device, the internal temperature of a refrigerator is usually lower than the outside ambient temperature. The cold air inside the refrigerator exchanges heat with the refrigerator door. Refrigerator door handles are typically recessed, meaning the distance between the handle and the refrigerator interior is small, resulting in a lower temperature at the handle area. When there is a significant temperature difference between the inside and outside of the refrigerator, condensation will form on the handle. This condensation easily attracts impurities from the air and corrodes the metal parts of the refrigerator door, affecting the refrigerator's quality and reducing user comfort.

[0039] In existing technologies, measures such as thickening the door or increasing the temperature at the handle are used to prevent condensation. Thickening the door increases the amount of raw materials used in production, inevitably increasing production costs. Furthermore, the increased door size makes the refrigerator larger, requiring more space for placement. Additionally, a thicker door restricts the opening angle, making it inconvenient for users and affecting the user experience. Increasing the temperature at the handle typically involves using anti-condensation tubes or adding heating wires. By raising the temperature of the handle area, the temperature difference between the inside and outside of the refrigerator is reduced, thus preventing condensation. However, both the operation of anti-condensation tubes and the continuous operation of heating wires consume additional electricity, increasing the overall energy consumption of the refrigerator and, in the long run, increasing the user's electricity costs.

[0040] Therefore, in this embodiment of the refrigerator door, a heat-conducting element 200 is provided at the handle 120 to reduce the temperature difference between the handle 120 and the outside environment, thereby effectively reducing the risk of condensation on the handle 120. See below for reference. Figures 1 to 10 The refrigerator door of this utility model embodiment is further described.

[0041] Reference Figure 1 and Figure 6As shown, it can be understood that the refrigerator door of this embodiment includes: a door liner 100, a panel 110, a handle 120, and a cooling guide 200. The panel 110 is the outermost part of the refrigerator door that directly faces the user, and the door liner 100 is usually located on the inner side of the refrigerator door. The first direction is the thickness direction of the handle 120, and the second direction is perpendicular to the first direction and parallel to the lateral direction of the handle 120. The panel 110 is disposed on one side of the door liner 100 along the first direction and defines an inner cavity 130 between the panel 110 and the door liner 100. The inner cavity 130 is used to fill with foam material, which can effectively prevent the cold air inside the refrigerator from exchanging heat with the hot air outside. A handle 120 connects the door frame 100 and the panel 110. The handle 120 includes a mounting portion 121, a first wall 122, and a second wall 123. The mounting portion 121 is connected to and fits against the panel 110. One end of the first wall 122 is connected to the mounting portion 121, and the other end extends toward the door frame 100. The second wall 123 is connected to the other end of the first wall 122. The first wall 122 and the second wall 123 have rounded corners. The mounting portion 121 and the second wall 123 are located on the same side of the first wall 122. A groove 124 is defined between the mounting portion 121 and the first wall 122 and the second wall 123. The groove 124 provides a gripping space for the user. The user can insert their fingers into the groove 124 to grasp the handle 120 to open and close the door, improving the convenience of opening and closing the door. It should be noted that in some other embodiments, the handle 120 can be located at the top, bottom or side of the refrigerator door, and the second direction adapts to the position of the refrigerator door.

[0042] The heat-conducting component 200 is located within the inner cavity 130 and connects the panel 110 and the second wall 123, with the heat-conducting component 200 and the first wall 122 spaced apart. The heat-conducting component 200 directs heat from the panel 110 to the second wall 123 of the handle 120, thereby increasing the temperature of the handle 120 and reducing the temperature difference between the handle 120 and the outside of the refrigerator. Furthermore, the heat-conducting component 200 ensures a more even temperature distribution on the second wall 123, preventing localized overcooling and effectively reducing the risk of condensation on the handle 120. Simultaneously, the heat-conducting component 200 precisely directs heat from the panel 110 to the second wall 123, rather than the first wall 122, further reducing the temperature difference between the second wall 123 and the outside of the refrigerator, thus minimizing the risk of condensation.

[0043] It should be noted that the cooling component 200 is made of a metallic material with good thermal conductivity. This excellent thermal conductivity allows the cooling component 200 to quickly transfer heat, accelerating the heat exchange process between the panel 110 and the second wall 123, improving heat transfer efficiency, and reducing the risk of condensation. The metallic material also possesses a certain degree of rigidity and strength, which enhances the structural stability of the cooling component 200. In other embodiments, the cooling component 200 may also be made of other thermally conductive materials well known to those skilled in the art, such as ceramics or diamond.

[0044] Reference Figures 1 to 5 As shown, the cooling component 200 includes a first plate 220, a transition plate 230, and a second plate 240. The transition plate 230 is connected to the first plate 220 and the second plate 240 and is bent relative to the first plate 220 and the second plate 240. The first plate 220 is connected to the panel 110 and fits tightly against the panel 110, which facilitates the transfer of heat from the panel 110 to the first plate 220. The second plate 240 is connected to the second wall 123 and fits tightly against the second wall 123, which facilitates the transfer of heat from the second plate 240 to the second wall 123. The cooling component 200 can be connected to the refrigerator door by adhesive or snap-fit ​​to ensure a tight seal, reduce gaps, and improve heat transfer. The transition plate 230 is spaced apart from the first wall 122 to prevent the heat from the cooling component 200 from being transferred to the first wall 122 via the transition plate 230, increasing the heat transferred to the second wall 123, thereby improving heat utilization efficiency. With panel 110 facing outwards, the first plate 220 transfers heat from panel 110 to the second plate 240 via the transition plate 230, and then from the second plate 240 to the second wall 123, thereby reducing the temperature difference between the second wall 123 and the outside, effectively reducing the generation of condensation.

[0045] Reference Figures 1 to 5 It is understandable that the maximum distance b between the end of the first plate 220 facing away from the transition plate 230 and the transition plate 230 is greater than or equal to the maximum distance a between the end of the second plate 240 facing away from the transition plate 230 and the transition plate 230, i.e., b ≥ a. When the lengths of the first plate 220 and the second plate 240 along the second direction are equal, the area of ​​the first plate 220 adhering to the panel 110 is greater than or equal to the area of ​​the second plate 240 adhering to the second wall 123. Since the panel 110 faces the outside and its temperature is higher than that of the second wall 123, the larger adhering area between the first plate 220 and the panel 110 facilitates the transfer of more heat from the panel 110 to the first plate 220. The heat from the first plate 220 is then conducted through the transition plate 230 to the second plate 240, and then to the second wall 123. This allows more heat from the panel 110 to be conducted to the second wall 123 through the heat-conducting component 200, thereby further reducing the temperature difference between the second wall 123 and the outside of the refrigerator, and reducing the risk of condensation.

[0046] It should be noted that the first plate 220 and the second plate 240 extend in opposite directions and are set in different planes, so that the first plate 220 can conduct heat to the panel 110 and the second plate 240 can conduct heat to the handle 120. Specifically, the connection between the first plate 220 and the second plate 240, which are in different planes, can be achieved through the transition plate 230.

[0047] In some embodiments of this utility model, the first plate 220, the second plate 240, and the transition plate 230 are integrally formed. The first plate 220, the second plate 240, and the transition plate 230 are obtained through sheet metal bending, thereby avoiding the drawback of heat transfer being blocked due to gaps between adjacent plates, and improving the heat conduction effect. That is, the first plate 220, the second plate 240, or the transition plate 230 are adaptively bent, with the second plate 240 and the first plate 220 forming a stepped shape, so that the second plate 240 can fit against the second wall 123 and connect with the transition plate 230, thereby conducting heat to the second wall 123.

[0048] In some embodiments of this utility model, reference is made to Figures 1 to 5 As shown, a first included angle β is formed between the transition plate 230 and the first plate 220, and a second included angle α is formed between the transition plate 230 and the second plate 240. The first included angle β is equal to the second included angle α. The first plate 220 is bent perpendicular to the transition plate 230, and the second plate 240 is bent perpendicular to the transition plate 230. That is, the included angle between the second plate 240 and the transition plate 230 is 90°, in order to adapt to the shape of the handle 120, so that the second plate 240 fits better against the second wall 123, ensuring the efficiency of heat conduction.

[0049] In some other embodiments of this utility model, to facilitate heat conduction between the second plate 240 and the transition plate 230 and the handle 120, the transition plate 230 and the second plate 240 are bent at an angle, with the included angle α greater than 90°. The first plate 220 and the second plate 240 are on different planes, allowing the second plate 240 to extend to fit the handle 120 for installation. The second plate 240 also better conforms to the second wall 123, ensuring efficient heat conduction. It is understood that the first included angle β and the second included angle α can be the same or different, and can be adjusted adaptively according to the relevant dimensions of the panel 110 and the second wall 123.

[0050] In some other embodiments of this utility model, the transition plate 230 is inclined, and the inclination angle of the transition plate 230 is equal to the inclination angle of the second plate 240, that is, the transition plate 230 and the second plate 240 are located on the same plane. The inclined length of the transition plate 230 is long enough to form a certain space with the first wall 122, which can prevent heat from being transferred to the first wall 122. The transition plate 230 and the second plate 240 are located on the same plane, which has a simple structure, facilitates the processing and forming of the cooling component 200, and reduces production costs.

[0051] According to one embodiment of this utility model, the first plate 220 is bonded to the panel 110, for example, by double-sided adhesive or hot melt adhesive, without the need for other connecting parts, which facilitates installation. The second plate 240 is bonded to the second wall 123, for example, by double-sided adhesive or hot melt adhesive, without the need for other connecting parts, which also facilitates installation.

[0052] Reference Figure 3 As shown, it can be understood that the cooling component 200 is provided with through holes 250, which connect the space between the transition plate 230 and the first wall 122. There are multiple through holes 250, which are arranged at intervals along the second direction on the cooling component 200. In this way, during the process of filling the inner cavity 130 of the refrigerator door with foam material, the foam material can fill the space between the transition plate 230 and the first wall 122 through the through holes 250 on the cooling component 200, preventing the heat of the cooling component 200 from being lost to the first wall 122 through the transition plate 230. This ensures the reliability of heat transfer of the cooling component 200, and allows the cooling component 200 to accurately guide the heat of the panel 110 to the second wall 123, thereby further reducing the temperature difference between the second wall 123 and the outside of the refrigerator, reducing the risk of condensation, and reinforcing the refrigerator door. A portion of the through-hole 250 is formed in the transition plate 230, and another portion is formed in the second plate 240; that is, the through-hole 250 is formed at the connection between the transition plate 230 and the second plate 240. When the foaming material expands, the transition plate 230 and the second plate 240 are subjected to the expansion force from the foaming material. Since the transition plate 230 and the second plate 240 have a first included angle α, the expansion forces acting on the transition plate 230 and the second plate 240 can partially cancel each other out, preventing the cooling component 200 from being displaced by force and also preventing the cooling component 200 from being deformed by pressure, thereby improving the structural stability of the cooling component 200.

[0053] Reference Figure 5 As shown, in other embodiments of this utility model, both the second plate 240 and the transition plate 230 are provided with multiple through holes 250. During the process of filling the inner cavity 130 of the refrigerator door with foam material, the foam material can enter the space between the transition plate 230 and the first wall 122 through the through holes 250 of the transition plate 230 and the second plate 240, which can make the filling more complete and prevent the heat inside the cooling component 200 from being lost to the first wall 122 through the transition plate 230. This ensures the reliability of heat transfer of the cooling component 200, so that the cooling component 200 mainly and accurately guides the heat of the panel 110 to the second wall 123, thereby further reducing the temperature difference between the second wall 123 and the outside of the refrigerator and reducing the risk of condensation.

[0054] In some embodiments of this utility model, through holes 250 are formed in transition plate 230. During the process of filling the inner cavity 130 of the refrigerator door with foam material, the foam material can enter the space between transition plate 230 and first wall 122 through through holes 250 on transition plate 230. This prevents the heat inside the cooling component 200 from being dissipated to the first wall 122 through transition plate 230, ensuring the reliability of heat transfer of cooling component 200. This allows cooling component 200 to accurately guide the heat of panel 110 to second wall 123, thereby further reducing the temperature difference between second wall 123 and the outside of the refrigerator and reducing the risk of condensation.

[0055] In some other embodiments of this utility model, through holes 250 are formed in the second plate 240. The foaming material can enter the space between the transition plate 230 and the first wall 122 through the through holes 250 in the second plate 240, avoiding the heat inside the cooling component 200 from being dissipated to the first wall 122 through the transition plate 230. This ensures the reliability of heat transfer in the cooling component 200, allowing the cooling component 200 to accurately guide the heat from the panel 110 to the second wall 123, thereby further reducing the temperature difference between the second wall 123 and the outside of the refrigerator and reducing the risk of condensation.

[0056] It should be noted that, referring to Figures 3 to 5 As shown, the through hole 250 can be circular, and multiple circular through holes 250 have the same diameter and their centers are located on the same straight line. The through hole 250 can also be elliptical, square, triangular or other shapes. Here, there is no restriction on the specific shape of the through hole 250 opened in the cooling component 200, as long as the through hole 250 has a sufficient size to fill the space between the transition plate 230 and the first wall 122 with foam material.

[0057] Furthermore, it can be understood that the first plate 220 and the second plate 240 are attached to the inner wall of the handle 120, while the foam material covers the first plate 220, the second plate 240, and the transition plate 230 to fix the cold-conducting component 200 and provide a certain degree of heat insulation. The foam material is a porous material, primarily polyurethane foam, which has an extremely low thermal conductivity. During the foaming process, the polyurethane foam exists in a liquid state, fully filling all corners and gaps inside the refrigerator door. After the foam material solidifies inside the door, it forms a robust foam structure, enhancing the overall strength and rigidity of the refrigerator door and reducing the loss of cold air inside the refrigerator as well as the intrusion of external heat, thus helping to maintain a stable low-temperature environment inside the refrigerator.

[0058] Reference Figure 3 and Figure 6As shown, the refrigerator door also includes uprights 300 connected to both ends of the handle 120 along the second direction. The uprights 300 are made of metal and have good thermal conductivity. The second direction is perpendicular to the first direction. The first plate 220 has folding plates 210 at both ends along the second direction. The height of the folding plates 210 along the first direction is less than the height of the transition plate 230 along the first direction. The folding plates 210 and the first plate 220 are integrally formed, thus avoiding gaps between adjacent plates, ensuring heat conduction of the cooling component 200 and enhancing its strength. The two folding plates 210 are connected to and fitted to the two uprights 300 respectively. The folding plates 210 increase the connection area and contact points with the uprights 300, reducing the risk of loosening or damage at the connection and facilitating the installation of the cooling component 200. The upright 300 is located on the outer perimeter of the refrigerator door and is in contact with the outside. Therefore, the temperature of the upright 300 is higher than that of the inside of the refrigerator. The folding plate 210 is in contact with the upright 300, which helps to conduct heat from the outside to the heat-conducting component 200. The heat-conducting component 200 then conducts the heat to the second wall 123, thereby further reducing the temperature difference between the handle 120 and the outside and reducing the risk of condensation. It should be noted that the first plate 220 and the folding plate 210 can be set at an angle or perpendicularly. The folding plates 210 at both ends of the first plate 220 can extend in the same direction or in opposite directions, which can be adapted according to the relevant structural design of the refrigerator door.

[0059] refer to Figures 3 to 5 As shown, it can be understood that along the second direction, the two ends of the first plate 220 protrude from the two ends of the transition plate 230, respectively. The width of the first plate 220 is greater than the width of the transition plate 230, and the width of the second plate 240 is equal to the width of the transition plate 230. This makes it easier to align the cooling component 200 to the preset position during installation. The wider first plate 220 can serve as a positioning base, while the smaller second plate 240 and transition plate 230 can be more easily embedded into the corresponding space, reducing installation difficulty, improving installation efficiency, and thus ensuring the reliability of the cooling component 200.

[0060] refer to Figure 6 As shown, along the second direction, the distance between the end of the folding plate 210 and the handle 120 is greater than the width of the column 300. There is a distance d1 between the end of the folding plate 210 and the handle 120, which is greater than the width of the column 300, meaning there is a gap between the end of the column 300 and the handle 120. When the inner cavity 130 of the handle 120 is filled with foam material, the foam material can enter the corners of the handle 120 through the gap, thereby ensuring good filling at the corners of the handle 120, improving the structural stability of the handle 120, ensuring the heat insulation performance of the handle 120, and reducing condensation.

[0061] In some embodiments of this utility model, reference is made to Figure 7 and Figure 9 As shown, the refrigerator door also includes a heat insulation component 400 located within the inner cavity 130. The heat insulation component 400 is connected to the door liner 100 and located at one end near the second wall 123. The heat insulation component 400 is hollow and vacuum-sealed, meaning it is a vacuum insulation panel that effectively blocks heat exchange between the refrigerator interior and the second wall 123. It should be noted that the heat insulation component 400 can also be made of high-efficiency insulation materials, such as polyurethane foam. The connection between the heat insulation component 400 and the door liner 100 can be achieved using double-sided adhesive or hot melt adhesive to reduce gaps and eliminate the need for additional connectors, simplifying installation.

[0062] refer to Figure 7 As shown, the door liner 100 has a recessed cavity 140, and the depth of the recessed cavity 140 matches the thickness of the heat insulation component 400 along the first direction. The heat insulation component 400 is accommodated in the recessed cavity 140, which effectively utilizes the space between the door liner 100 and the inner cavity 130, making the structure of the inner cavity 130 of the refrigerator door more compact, reducing the space occupied by the heat insulation component 400 in the refrigerator door, and improving the space utilization rate of the inner cavity 130. The recessed cavity 140 in the door liner 100 can accommodate the heat insulation component 400 while ensuring that the refrigerator door has a certain thickness of foam filling material, making it suitable for thinner refrigerator doors. It should be noted that since the heat insulation component 400 is located at the end of the door liner 100 near the second wall 123, the heat insulation component 400 can effectively block heat exchange between the inside of the refrigerator and the second wall 123, reducing the temperature difference between the second wall 123 and the outside of the refrigerator, and reducing the risk of condensation.

[0063] In some embodiments of this utility model, reference is made to Figure 9 and Figure 10 As shown, along the second direction, the heat insulation component 400 maintains a distance d2 from the end of the handle 120, meaning there is a gap between the two ends of the heat insulation component 400 and the door liner 100. When the inner cavity 130 of the handle 120 is filled with foam material, the foam material can enter the side of the heat insulation component 400 through the gap and cover the heat insulation component 400. The gap ensures that the heat insulation component 400 is well filled on all sides, improving the installation stability of the heat insulation component 400. Since the low-temperature area inside the refrigerator is mainly located in the middle area along the second direction, the gap between the two ends of the heat insulation component 400 and the door liner 100 does not affect the function of the heat insulation component 400 in blocking heat exchange between the inside of the refrigerator and the second wall 123.

[0064] In other embodiments of this utility model, reference is made to Figure 8 and Figure 9As shown, the heat insulation component 400 is connected to the second wall 123. Since the heat insulation component 400 occupies part of the internal space of the refrigerator door, the door body needs to be thickened to ensure the filling thickness of the foam material in the refrigerator door and to ensure the heat insulation effect of the refrigerator door. The heat insulation component 400 is adapted to the inclined shape of the second wall 123. The heat insulation component 400 can be bonded to the second wall 123 with double-sided tape or hot melt adhesive to reduce connection gaps and eliminate the need for other connectors, making installation convenient. The heat insulation component 400 acts directly on the second wall 123, which can block heat exchange between the inside of the refrigerator and the second wall 123 to the greatest extent, thereby further reducing the temperature difference between the second wall 123 and the outside of the refrigerator and reducing the risk of condensation.
