Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and more particularly to a refrigerator. Background Technology

[0002] To allow users to see what's inside the refrigerator while preventing cold air from leaking out, more and more refrigerators are featuring hollow, transparent glass windows on their doors, allowing users to view the interior without opening the door.

[0003] In related technologies, transparent glass windows typically include inner glass, outer glass, and a spacer between the inner and outer glass, forming a hollow structure. To reduce the transfer of cold air inside the refrigerator and prevent condensation on the transparent glass window, a heat-insulating medium (such as argon gas) is usually added between the hollow structure of the transparent glass window. However, due to the high thermal conductivity of the spacer, the cold air inside the refrigerator can still easily be transferred to the outer glass through the inner glass and the spacer, resulting in condensation on the outer glass and affecting the display effect of the transparent glass window. Utility Model Content

[0004] This application discloses a refrigerator that can extend the conduction path of cold air inside the refrigerator to the second transparent plate, thereby reducing the amount of cold air transferred to the second transparent plate and keeping the surface temperature of the second transparent plate above the dew point, thus avoiding the problem of condensation on the second transparent plate.

[0005] To achieve the above objectives, embodiments of this application disclose a refrigerator, comprising:

[0006] The container has a storage compartment;

[0007] A door, movably connected to the housing to open or close the storage compartment, the door comprising:

[0008] Door frame;

[0009] A door insert, which is connected to the inner side of the door frame to form a foam cavity for filling with foam material between the door insert and the door frame, and the door insert has a first connecting part;

[0010] A transparent panel assembly, the transparent panel assembly being connected to the outside of the door frame;

[0011] The transparent panel assembly includes:

[0012] A first transparent plate, the first transparent plate being connected to the first connecting portion of the door frame;

[0013] The second transparent panel is spaced apart from the first transparent panel along the thickness direction of the door body, and the second transparent panel covers the opening on the outside of the door frame;

[0014] A spacer is connected between the first transparent plate and the second transparent plate, and the spacer is used to form a closed heat insulation cavity between the first transparent plate and the second transparent plate, the heat insulation cavity being filled with argon gas;

[0015] In the first direction, the edge side of the first transparent plate and the spacer are both located between the door frame and the first connecting part of the door frame, and the projection of the spacer on the first transparent plate is offset from the projection of the first connecting part of the door frame on the first transparent plate, and the edge side of the first transparent plate is located in the foaming cavity.

[0016] Wherein, the first direction is the width direction or the height direction of the door body.

[0017] Because the foaming cavity contains foaming material and the insulation cavity contains argon gas, and the thermal conductivity of the first transparent plate, the spacer, and the second transparent plate is higher than that of the foaming material and argon gas, the cold air inside the refrigerator is first transferred from the door liner to the first transparent plate, the spacer, and the second transparent plate. By positioning the edge of the first transparent plate and the spacer between the door frame and the first connection point of the door liner, and by offsetting the projection of the spacer on the first transparent plate from the projection of the first connection point of the door liner, and with the edge of the first transparent plate located within the foaming cavity, the path of cold air transfer from the door liner through the first transparent plate to the spacer is extended. Therefore, the rate at which cold air is transferred from the first transparent plate to the spacer and the second transparent plate is slower, thus slowing down the transfer of cold air from the inside of the refrigerator to the outside. This reduces the loss of cold air and improves the refrigerator's insulation performance. It also reduces the total amount of cold air transferred to the second transparent plate, keeping its surface temperature above the dew point, effectively preventing condensation on the second transparent plate and improving the refrigerator's display effect.

[0018] As an optional implementation, along the first direction, the minimum distance between the spacer and the first connecting portion is L1, where L1 satisfies: L1≥5mm.

[0019] By setting the distance L1 between the spacer and the first connecting part to be ≥ 5mm, the path of cold air from the inside of the refrigerator through the first transparent plate to the spacer can be further extended. This ensures that the cold air transfer path from the door liner through the first transparent plate to the spacer is long enough, thereby effectively slowing down the speed at which cold air is transferred to the second transparent plate. This design not only improves the refrigerator's insulation performance and reduces cold air loss, but also ensures that the surface temperature of the second transparent plate can be maintained above the dew point, effectively preventing condensation. For example, L1 can be 5mm, 6mm, 7mm, 8mm, 9mm, etc., and this application embodiment does not limit this.

[0020] As an optional implementation, along the first direction, the maximum distance from the edge of the first transparent plate to the first connecting portion is L2, where L2 satisfies: L2≥10mm.

[0021] By setting the distance L1 between the edge of the first transparent panel and the first connecting part of the door liner to satisfy L2≥10mm, the cold energy transfer path can be further extended using the spacer. Simultaneously, the size of the first transparent panel is large enough to provide a sufficiently long transfer path for the cold energy, ensuring that the cold energy transfer path from the door liner through the first transparent panel to the spacer is long enough, thereby effectively slowing down the speed at which the cold energy is transferred to the second transparent panel. This design not only improves the refrigerator's insulation performance and reduces cold energy loss, but also ensures that the surface temperature of the second transparent panel can be maintained above the dew point, effectively preventing condensation. At the same time, the reasonable distance setting also ensures the structural strength and stability of the transparent panel assembly, further improving its service life and overall aesthetics. For example, L2 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc., and this application embodiment does not limit this.

[0022] As an optional implementation, in the first direction, the distance from the projection of the spacer onto the first transparent plate to the first connecting portion of the door frame is H1, and the distance from the projection of the spacer onto the first transparent plate to the edge side of the first transparent plate is H2, wherein H1 > H2.

[0023] By setting H1 > H2, that is, along the first direction, the distance between the spacer and the door liner is greater than the distance between the spacer and the first connecting part of the first transparent plate, the path of cold energy being transferred from the first transparent plate to the spacer can be further extended, thereby effectively slowing down the speed at which cold energy is transferred to the second transparent plate, thus effectively avoiding the problem of condensation on the second transparent plate and improving the display effect of the refrigerator.

[0024] As an optional implementation, the door frame includes:

[0025] A door frame body, which is connected to the inside of the door frame and extends to the outside of the door frame;

[0026] A bending portion, one end of which is bent and connected to the edge side of the door body, and the other end of which extends in a direction away from the foaming cavity to connect to the first transparent plate, wherein the bending portion is configured as the first connecting portion.

[0027] The spacer is disposed near the edge of the first transparent plate and at the other end away from the bend.

[0028] By incorporating a bend in the door liner to connect the first transparent panel, the contact area between the first transparent panel and the door liner is increased. This not only allows the bend to support the first transparent panel, thus improving the reliability of the connection between the first transparent panel and the door liner, but also enhances the seal between the door liner and the first transparent panel. This prevents the foam material from entering the interior of the door liner and also avoids cold leakage from the connection between the door liner and the first transparent panel. Furthermore, the bend design further strengthens the structural strength of the door liner.

[0029] For example, the first connecting part mentioned above can be the edge side of the door frame or the bent part of the door frame, and this application does not limit it in this way.

[0030] As an alternative implementation, the other end of the bent portion extends along the first direction, and the distance from the spacer to the other end of the bent portion along the first direction is greater than or equal to 5 mm.

[0031] By setting the bending portion to extend along the width or height direction of the door body, and ensuring that the distance from the spacer to the other end of the bending portion is greater than or equal to 5mm, the path for cold air inside the refrigerator to be transferred from the inside of the door liner through the first transparent plate to the spacer is further extended. This ensures that the transfer path of cold air from the door liner through the first transparent plate to the spacer is sufficiently long, thereby effectively slowing down the speed at which cold air is transferred to the second transparent plate. This design not only improves the refrigerator's insulation performance and reduces cold air loss, but also ensures that the surface temperature of the second transparent plate can be maintained above the dew point, effectively preventing condensation. For example, the distance from the spacer to the other end of the bending portion can be 5mm, 6mm, 7mm, 8mm, 9mm, etc., and this application embodiment does not limit this.

[0032] As an optional implementation, the first transparent panel includes multiple panels, and the multiple first transparent panels and the second transparent panel are arranged at intervals along the thickness direction of the door body;

[0033] The spacer includes a plurality of spacers, with the spacer connecting two adjacent first transparent plates, and the spacer also connecting the second transparent plate and the first transparent plate adjacent to the second transparent plate;

[0034] The heat insulation cavity includes:

[0035] The first sub-cavity is formed between the spacer and two adjacent first transparent plates;

[0036] The second sub-cavity is formed between the spacer and the second transparent plate, and between the first transparent plate adjacent to the second transparent plate. Both the first sub-cavity and the second sub-cavity are filled with argon gas.

[0037] By using multiple first transparent plates to divide the insulation cavity into a first sub-cavity and a second sub-cavity, both filled with argon gas, the heat transfer path between the first transparent plates is made more circuitous, lengthening the heat transfer path and further slowing down the transfer of cold energy from the refrigerator interior to the second transparent plate. With the transparent panel assembly formed by multiple first and second transparent plates, cold energy needs to undergo multiple heat conduction processes to transfer from the refrigerator interior to the second transparent plate. This process further reduces the total amount of cold energy transferred to the second transparent plate, allowing its surface temperature to be better maintained above the dew point, effectively preventing condensation. Furthermore, the transparent panel assembly composed of multiple first and second transparent plates also improves its overall strength and stability, enhances its resistance to external impacts, and further extends the service life of the transparent panel assembly.

[0038] As an alternative implementation method,

[0039] Along the second direction, a plurality of the spacers are correspondingly arranged; or,

[0040] The dimensions of the plurality of first transparent plates and second transparent plates increase sequentially in the second direction along the first direction, and the plurality of spacers are staggered along the second direction;

[0041] The second direction is the direction from the inside of the door frame to the outside of the door frame.

[0042] Multiple first transparent panels and second transparent panels are spaced apart, with spacers between adjacent first transparent panels and between adjacent first and second transparent panels. These spacers are arranged correspondingly along a second direction, making the cold air transfer path inside the refrigerator more regular and preventing cold air from becoming disordered during transfer, thereby further improving the refrigerator's heat preservation performance. At the same time, the corresponding spacers also enhance the structural strength of the transparent panel assembly, improving its overall stability.

[0043] Alternatively, by setting multiple first transparent panels and second transparent panels with their dimensions increasing sequentially along the second direction from the first direction, the layout of the transparent panel assembly on the door can be more rational, ensuring the heat insulation performance of the transparent panel assembly. Furthermore, by staggering multiple spacers along the second direction, the conduction path of cold air can be further extended, while making the transfer of cold air between the first transparent panel, spacers, and second transparent panel more complex. This effectively slows down the rate at which cold air is transferred from the inside of the refrigerator to the second transparent panel, further reducing the likelihood of condensation on the second transparent panel.

[0044] As an alternative implementation, the second transparent panel includes a visible area and a non-visible area surrounding the outer periphery of the visible area, with the visible area corresponding to the first transparent panel.

[0045] That is, the visible area is roughly located in the middle of the second transparent panel, and the non-visible area is arranged around the visible area. This allows users to observe the contents of the storage room through the visible area, and also to use the non-visible area to cover the seals, spacers, and other components inside the door of the transparent panel assembly, making the refrigerator look simpler and more beautiful.

[0046] As an alternative implementation, the transparent panel assembly further includes a heating element disposed around the outer periphery of the spacer.

[0047] By surrounding the spacer with heating elements, the heat transfer path is further blocked by the heating elements. The heat generated by the heating elements compensates for the temperature drop near the second transparent panel caused by the transfer of cold air, allowing the surface temperature of the second transparent panel to be maintained above the dew point, effectively preventing condensation. Furthermore, surrounding the spacer with heating elements ensures their safe and reliable operation while avoiding any adverse effects on the light transmittance and overall aesthetics of the transparent panel assembly.

[0048] For example, the heating element may include heating wires, heating films, and other heating elements. Its working power and heating temperature can be adjusted according to the actual use environment and needs of the refrigerator to achieve a balance between energy consumption and anti-condensation effect.

[0049] Optionally, the heating element can be positioned in the middle of the insulation cavity along the thickness of the door. If the heating element is too close to the door liner, the heat emitted by the heating element will exchange with the cold air inside the refrigerator, causing a loss of cold air. If the heating element is too close to the second transparent panel, the heat generated by the heating element will not have enough time to exchange with the cold air before being directly transferred to the second transparent panel, causing condensation to form on the second transparent panel. Therefore, positioning the heating element in the middle of the insulation cavity along the thickness of the door allows the heat generated by the heating element to act more evenly on the spacer and the second transparent panel, further improving the anti-condensation effect.

[0050] As an alternative implementation, the transparent panel assembly further includes a seal disposed between the first transparent panel and the second transparent panel, and surrounding the outer periphery of the spacer.

[0051] By setting a seal between the first transparent plate and the second transparent plate, and with the seal surrounding the outer periphery of the spacer, the heat insulation performance of the transparent panel assembly can be further enhanced. The seal can also strengthen the structural strength of the first and second transparent plates, providing a certain degree of protection for the transparent panel assembly, preventing it from being damaged by external impacts, and extending the service life of the transparent panel assembly.

[0052] For example, the sealant can be a sealant or sealing foam, which has good elasticity and sealing properties, effectively preventing cold air from leaking from the edges of the transparent panel assembly, thereby improving the refrigerator's insulation performance. At the same time, the sealant also prevents external moisture or dust from entering the interior of the transparent panel assembly, maintaining its cleanliness and transparency, further enhancing the user's viewing experience.

[0053] As an optional implementation, the door panel has an accommodating space corresponding to the first transparent panel;

[0054] The door also includes:

[0055] A lighting assembly is disposed above the door frame along the height direction of the door body, and the lighting assembly emits light towards the accommodating space.

[0056] By installing a lighting component on the door panel, aligning it with the first transparent panel and the storage space, and emitting light towards this space, the light passes through the first transparent panel into the storage space, then through the second transparent panel before passing through to the outside. This improves the light transmittance of the transparent panel assembly, allowing users to more clearly observe the items inside the storage compartment. Simultaneously, the lighting component adds to the refrigerator's aesthetics and enhances the user experience.

[0057] Compared with the prior art, the beneficial effects of this application are:

[0058] The refrigerator disclosed in this application includes a cabinet and a door, with the door movably connected to the cabinet to open or close the storage compartment. The door includes a door frame, a door liner, and a transparent panel assembly. The door liner is connected to the inner side of the door frame to form a foam cavity for filling with foam material. The transparent panel assembly is connected to the outer side of the door frame. The transparent panel assembly includes a first transparent plate, a second transparent plate, and a spacer. The first transparent plate is connected to the door liner, and the second transparent plate is spaced apart from the first transparent plate, covering an opening on the outer side of the door frame. The spacer is connected between the first and second transparent plates, forming a closed heat-insulating cavity between them, which is filled with argon gas. In a first direction, the edge of the first transparent plate and the spacer are both located between the edge of the door frame and the edge of the door liner, and the projection of the spacer on the first transparent plate is offset from the projection of the first connecting portion of the door liner on the first transparent plate. The edge of the first transparent plate is located within the foam cavity. The first direction refers to either the width direction or the height direction of the door.

[0059] Because both the foaming cavity and the insulation cavity contain foaming material and argon gas, and the thermal conductivity of the first transparent plate, the spacer, and the second transparent plate is higher than that of the foaming material and argon gas, the cold air inside the refrigerator is first transferred from the door liner to the first transparent plate, the spacer, and the second transparent plate. By positioning the edge of the first transparent plate and the spacer between the door frame and the first connection part of the door liner, and by offsetting the projection of the spacer on the first transparent plate from the projection of the first connection part of the door liner on the first transparent plate, and with the edge of the first transparent plate located in the foaming cavity, the path of cold air transfer from the door liner through the first transparent plate to the spacer is extended. Therefore, the rate at which cold air is transferred from the first transparent plate to the spacer and the second transparent plate is slower, thus slowing down the transfer of cold air from the inside of the refrigerator to the outside, reducing the loss of cold air, improving the refrigerator's insulation performance, and reducing the total amount of cold air transferred to the second transparent plate. This keeps the surface temperature of the second transparent plate above the dew point, effectively preventing condensation on the second transparent plate and improving the refrigerator's display effect.

[0083] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0084] In this application, the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0085] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain circumstances to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0086] Furthermore, the terms "installation," "setup," "equipped with," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0087] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0088] In the description of this application, it should be noted that the singular forms of "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that terms such as "comprising / including" or "having" specify the presence of the stated features, integrals, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integrals, steps, operations, components, parts, or combinations thereof.

[0089] Refrigerators typically have a refrigerator compartment and a freezer compartment for refrigerating and freezing foods. To allow users to observe the contents of the refrigerator without opening the door, and to reduce cold air leakage, some refrigerators use a hollow, transparent glass window in the door. This structure usually consists of an inner glass panel, an outer glass panel, and a spacer, which together form a hollow cavity. Insulation media such as argon gas are used to reduce cold air transfer and prevent condensation on the outer glass panel.

[0090] In related technologies, the high thermal conductivity of the spacer becomes a weak link in the transfer of cold energy, making it easy for the cold energy inside the refrigerator to be quickly conducted along the path of the inner glass, the spacer and the outer glass. This results in the outer glass being too cold. When the surface temperature of the outer glass is lower than the dew point temperature of the ambient air, water vapor in the air will condense into fog or water droplets on the surface of the outer glass. In severe cases, this will affect the light transmittance and display effect of the window.

[0091] In view of this, the refrigerator disclosed in this application can extend the conduction path of cold air inside the refrigerator to the second transparent plate, thereby reducing the amount of cold air transferred to the second transparent plate and keeping the surface temperature of the second transparent plate above the dew point, thus avoiding the problem of condensation on the second transparent plate.

[0092] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0093] Please refer to the following: Figures 1 to 2 , Figure 1 This is a schematic diagram of the structure of the refrigerator provided in an embodiment of this application. Figure 2This is an exploded view of the refrigerator provided in the embodiments of this application. The refrigerator 100 disclosed in this application can be, for example, a double-door refrigerator, a single-door refrigerator, a three-door refrigerator, or a French door refrigerator. Alternatively, it can be a French door refrigerator, that is, the upper part is a double-door refrigerator compartment providing ample storage space for users, and the lower part is usually a drawer-type freezer compartment, making it easier to classify, store, and access frozen foods. The specific form is not limited in the embodiments of this application.

[0094] In some embodiments, the refrigerator 100 includes a cabinet 101 defining a storage compartment 101a for storing food. The storage compartment 101a may include a freezer compartment, a refrigerator compartment, or a variable temperature compartment, etc.

[0095] Understandably, the temperature of a refrigerator compartment is typically between 2°C and 8°C, which keeps food refrigerated. The temperature of a freezer compartment is typically between -14°C and -26°C, which keeps food frozen. The temperature of a variable-temperature compartment is generally adjustable between 5°C and -7°C, or it can be directly set to -18°C for use as a freezer.

[0096] Please refer to the following: Figures 3 to 4 , Figure 3 This is a front view of the refrigerator provided in the embodiment of this application. Figure 4 yes Figure 3 Cross-sectional view of AA. In some embodiments, the refrigerator 100 includes a door 102, which is movably connected to the cabinet 101 to open or close the storage compartment 101a to prevent cold air from leaking out of the storage compartment 101a.

[0097] Optionally, the refrigerator 100 may include two independent doors 102, both of which are rotatably connected to the cabinet 101 and can be opened from the sides of the two doors 102 that are close to each other. Of course, in some embodiments, the refrigerator 100 may include a single independent door 102, one side of which is rotatably connected to the cabinet 101 and can be opened from the other side of the door 102.

[0098] It is understood that the door 102 has an inner side and an outer side along its thickness direction X. When the door 102 is closed, the inner side of the door 102 is usually facing the storage room 101a, and the outer side of the door 102 is the side exposed to the outside of the storage room 101a, which is usually facing the user or can be operated by the user.

[0099] Please refer to the following: Figures 5 to 7 , Figure 5 This is one of the structural schematic diagrams of the door provided in the embodiments of this application. Figure 6 This is an exploded view of the door provided in the embodiment of this application. Figure 7This is a second structural schematic diagram of the door body provided in this application embodiment. In some embodiments, the door body 102 may include a door frame 10 and a door insert 20. The door frame 10 is movably connected to the housing 101, and the door insert 20 is disposed inside the door frame 10. When the door body 102 is closed, the door insert 20 faces the storage chamber 101a. A foam cavity 10a is usually formed between the door frame 10 and the door insert 20. The foam cavity 10a is used to fill foam material (not shown) to improve the thermal insulation performance of the door body 102 and prevent cold air leakage. Since the thermal conductivity of the foam material is low, by filling the foam cavity 10a with foam material, the thermal conductivity inside the foam cavity 10a can be reduced, thereby reducing the possibility of cold air being transferred from the door insert 20 to the foam cavity 10a and the door frame 10.

[0100] It is understandable that the outer side of the door frame 10 corresponds to the outer side of the door body 102, and the inner side of the door frame 10 corresponds to the inner side of the door body 102.

[0101] It is understandable that foaming materials can include polyurethane foam, polystyrene foam, or phenolic foam, etc. These foaming materials have good thermal insulation properties, effectively preventing the transfer of cold air and improving the insulation effect of the refrigerator.

[0102] In some embodiments, the door 102 includes a transparent panel assembly 30, which is connected to the outside of the door frame 10. Without opening the door 102 of the refrigerator 100, the user can directly observe the items inside the storage compartment 101a through the transparent panel assembly 30. The transparent panel assembly 30, while reducing the loss of cold air inside the refrigerator 100, satisfies the user's need to observe the items inside the storage compartment 101a and maintains the overall aesthetics of the refrigerator 100.

[0103] In some embodiments, the door 102 further includes a lighting assembly 40, which is disposed above the door insert 20 along the height direction Z of the door 102. The door insert 20 has an accommodating space 20a corresponding to the first transparent panel 31, and the lighting assembly 40 emits light towards the accommodating space 20a. By setting the lighting assembly 40 on the door insert 20, so that the door insert 20 is positioned corresponding to the first transparent panel 31 and the accommodating space 20a, and the lighting assembly 40 emits light towards the accommodating space 20a, light can pass through the first transparent panel 31 into the accommodating space 20a, and then pass through the second transparent panel 32 to the outside, improving the light transmittance of the transparent panel assembly 30, allowing the user to more clearly observe the items in the storage compartment 101a. At the same time, the lighting assembly 40 can also add a certain aesthetic appeal to the refrigerator 100 and enhance the user experience.

[0104] Please refer to sections 3 to 4 as well. Figure 8 , Figure 8This is a front view of the door body provided in an embodiment of this application. In some embodiments, the second transparent panel 32 includes a visible area 321 and a non-visible area 322 surrounding the visible area 321. The visible area 321 is provided corresponding to the first transparent panel 31. That is, the visible area 321 is generally located in the middle of the second transparent panel 32, and the non-visible area 322 is arranged around the visible area 321, so that the user can observe the items in the storage compartment 101a through the visible area 321, and can also use the non-visible area 322 to cover the spacer 40, seal 34, etc. of the transparent panel assembly 30, as well as other components inside the door body 102, thereby making the appearance of the refrigerator 100 more concise and beautiful.

[0105] Please refer to the following: Figures 9 to 10A , Figure 9 yes Figure 8 Sectional view of BB, Figure 10A yes Figure 8 A cross-sectional view of the center (CC). In some embodiments, the transparent panel assembly 30 includes a first transparent plate 31, a second transparent plate 32, and a spacer 40. The first transparent plate 31 is connected to the door liner 20 along the thickness direction X of the door body 102. The second transparent plate 32 is spaced apart from the first transparent plate 31 and covers the opening on the outside of the door frame 10. The spacer 40 is connected between the first transparent plate 31 and the second transparent plate 32, and the spacer 40 is used to form a closed heat insulation cavity 33a between the first transparent plate 31 and the second transparent plate 32. The heat insulation cavity 33a is used to fill argon gas. By introducing argon gas into the insulation cavity 33a, the thermal conductivity of the cavity is reduced due to the low thermal conductivity of argon gas. This reduces the speed at which cold energy is transferred from the first transparent plate 31 to the second transparent plate 32 via the spacer 40, further slowing down the speed at which cold energy is transferred from the inside of the refrigerator 100 to the outside of the refrigerator 100. Consequently, the possibility of cold energy being transferred to the second transparent plate 32 via the first transparent plate 31 and the insulation cavity 33a is reduced.

[0106] In some embodiments, the door liner 20 includes a door liner body 21 and a bending portion 22. The door liner body 21 is connected to the inner side of the door frame 10 and extends to the outer side of the door frame 10. One end of the bending portion 22 is bent and connected to the edge side 211 of the door liner body 21, and the other end of the bending portion 22 extends in a direction away from the foaming cavity 10a to be connected to the first transparent plate 31. The bending portion 22 is substantially parallel to the first transparent plate 31. The bending portion 22 is used to support the first transparent plate 31, thereby increasing the contact area between the door liner 20 and the first transparent plate 31, and thus improving the connection strength and sealing performance between the door liner 20 and the first transparent plate 31.

[0107] In some embodiments, the door insert 20 has a first connecting portion 201 for connecting to the first transparent plate 31. Exemplarily, the edge side 211 of the door insert body 21 can be configured as the first connecting portion 201. Alternatively, a bending portion 22 can be provided on the edge side 211 of the door insert body 21. The bending portion 22 bends relative to the edge side 211 of the door insert body 21 and extends in a direction away from the foaming cavity 10a. The bending portion 22 can be configured as the first connecting portion 201. This application embodiment does not limit this.

[0108] Figure 9 and Figure 10A The dashed arrows indicate the path of cold air transfer. In some embodiments, in the first direction F1, the edge of the first transparent plate 31 and the spacer 33 are both located between the first connecting portion 201 of the door frame 10 and the door liner 20. The projection of the spacer 33 on the first transparent plate 31 is offset from the projection of the first connecting portion 201 of the door liner 20 on the first transparent plate 31. The edge of the first transparent plate 31 is located in the foaming cavity 10a. Since the foaming cavity 10a is provided with foaming material and the insulation cavity 33a is provided with argon gas, and the thermal conductivity of the first transparent plate 31, the spacer 40, and the second transparent plate 32 is higher than that of the foaming material and argon gas, the cold air inside the refrigerator 100 will be transferred sequentially from the door liner 20 to the first transparent plate 31, the spacer 40, and the second transparent plate 32. As indicated by the dashed arrow in the figure, the cold energy transfer path is such that by setting the edge of the first transparent plate 31 and the spacer 33 to be located between the first connection 201 of the door frame 10 and the door liner 20, and the spacer 33 to be located away from the first connection 201 of the door liner 20, the edge of the first transparent plate 31 is located in the foaming cavity 10a. This extends the cold energy transfer path from the door liner 20 through the first transparent plate 31 to the spacer 40. Therefore, the rate at which cold energy is transferred from the first transparent plate 31 to the spacer 40 and the second transparent plate 32 is slower, thus slowing down the speed at which cold energy is transferred from the inside of the refrigerator 100 to the outside of the refrigerator 100. This reduces the loss of cold energy in the refrigerator 100, improves the heat preservation performance of the refrigerator 100, and also reduces the total amount of cold energy transferred to the second transparent plate 32. This keeps the surface temperature of the second transparent plate 32 above the dew point, effectively avoiding the problem of condensation on the second transparent plate 32 and improving the display effect of the refrigerator 100.

[0109] It is understood that the first direction F1 can be the width direction Y of the door body 102, or the first direction F1 can be the height direction Z of the door body 102. This application embodiment does not limit this.

[0110] Optionally, the spacer 40 can be a spacer strip, the material of the spacer 40 can be aluminum, stainless steel or composite material, etc., and the structure of the spacer 40 can be strip-shaped or block-shaped, etc., which are not limited in this application embodiment.

[0111] It should be noted that the projection of the spacer 33 on the first transparent plate 31 is offset from the projection of the first connecting part 201 of the door frame 20 on the first transparent plate 31. This includes cases where the projection of the spacer 33 on the first transparent plate 31 is completely offset from the projection of the first connecting part 201 of the door frame 20, or cases where the projection of the spacer 33 on the first transparent plate 31 is completely offset from the projection of the first connecting part 201 of the door frame 20, which will be explained separately below.

[0112] In one example, such as Figure 9 As shown, the projection of the spacer 33 onto the first transparent plate 31 is completely offset from the first connecting portion 201 of the door frame 20. In this case, any position of the orthographic projection of the spacer 33 onto the first transparent plate 31 is offset from the first connecting portion 201, and there is a gap between them. In other words, the edge of the orthographic projection of the spacer 33 onto the first transparent plate 31 closest to the first connecting portion 201 is not aligned with the edge of the first connecting portion 201, and there is a gap between them.

[0113] In another example, such as Figure 10B As shown, the projection of the spacer 33 onto the first transparent plate 31 is partially offset from the first connecting portion 201 of the door frame 20. In this case, a portion of the orthographic projection of the spacer 33 onto the first transparent plate 31 may be offset from the first connecting portion 201 of the door frame 20, while a portion may overlap with the first connecting portion 201 of the door frame 20. For example, the portion of the orthographic projection of the spacer 33 onto the first transparent plate 31 closest to the first connecting portion 201 of the door frame 20 overlaps with the first connecting portion 201 of the door frame 20 (including the edge of the orthographic projection of the spacer 33 onto the first transparent plate 31 closest to the first connecting portion 201 being flush with the edge of the first connecting portion 201, or the edge of the orthographic projection of the spacer 33 onto the first transparent plate 31 closest to the first connecting portion 201 falling on the first connecting portion 201), but the portion of the orthographic projection of the spacer 33 away from the first transparent plate 31 (the portion closer to the edge of the first transparent plate 31) is offset from the first connecting portion 201 of the door frame 20.

[0114] It should be noted that the edge side 211 of the door body 21 can be constructed as the first connecting part 201, or the bent part 22 can be constructed as the first connecting part 201.

[0115] Therefore, see Figure 9 and Figure 10BWhen the first connecting part 201 is configured as a bent part 22, the spacer 33 is located between the door frame 10 and the bent part 22, and the projection of the spacer 33 on the first transparent plate 31 is offset from the projection of the bent part 22 on the first transparent plate 31.

[0116] Or see Figure 10C and Figure 10D When the first connecting part 201 is configured as the edge side 211 of the door frame 21, the spacer 33 is located between the door frame 10 and the edge side 211 of the door frame 21. The projection of the spacer 33 on the first transparent plate 31 is offset from the projection of the edge side 211 of the door frame 21 on the first transparent plate 31.

[0117] In some embodiments, when the orthographic projection of the spacer 33 on the first transparent plate 31 is misaligned with the first connecting portion 201 of the door frame 20, the minimum distance between the spacer 33 and the first connecting portion 201 along the first direction F1 can be L1, where L1 satisfies: L1≥5mm.

[0118] By setting a spacer 33 along the first direction F1 between the first connecting portion 201 of the door liner 20 and the edge side of the first transparent plate 31, and staggering the projection of the spacer 33 on the first transparent plate 31 with the projection of the first connecting portion 201 of the door liner 20 on the first transparent plate 31, with the minimum staggered distance L1 between the spacer 33 and the first connecting portion 201 satisfying L1≥5mm, the path of cold air inside the refrigerator 100 from the door liner 20 through the first transparent plate 31 to the spacer 33 is further extended, ensuring that the cold air transmission path from the door liner 20 through the first transparent plate 31 to the spacer 33 is long enough, thereby effectively slowing down the speed at which cold air is transferred to the second transparent plate 32. This design not only improves the heat preservation performance of the refrigerator 100 and reduces the loss of cold air, but also ensures that the surface temperature of the second transparent plate 32 can be maintained above the dew point, effectively preventing condensation. For example, L1 can be 5mm, 6mm, 7mm, 8mm, 9mm, etc., and this application embodiment does not limit this. Of course, as another example, the minimum distance L1 can also be L1≥2mm, for example, it can be 2mm, 3mm, 4mm, etc., as long as the projection of the spacer on the first transparent plate and the first connecting part are staggered.

[0119] In some embodiments, along the first direction F1, the maximum distance from the edge of the first transparent panel 31 to the first connecting portion 201 of the door liner 20 is L2, where L2 ≥ 10 mm. By setting the maximum distance L2 from the edge of the first transparent panel 31 to the first connecting portion 201 of the door liner 20 to satisfy L2 ≥ 10 mm, the spacer 40 can be used to further extend the cold energy transmission path, while the size of the first transparent panel 31 is large enough to provide a sufficiently long transmission path for the cold energy. This ensures that the cold energy transmission path from the door liner 20 through the first transparent panel 31 to the spacer 40 is long enough, thereby effectively slowing down the speed at which the cold energy is transmitted to the second transparent panel 32. This design not only improves the heat preservation performance of the refrigerator 100 and reduces the loss of cold energy, but also ensures that the surface temperature of the second transparent panel 32 can be maintained above the dew point, effectively preventing condensation. At the same time, the reasonable distance setting also ensures the structural strength and stability of the transparent panel assembly 30, further improving its service life and overall aesthetics. For example, L2 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc., and this application embodiment does not limit it.

[0120] In some embodiments, in the first direction F1, the distance from the projection of the spacer 40 on the first transparent plate 31 to the first connecting portion 201 of the door frame 20 is H1, and the distance from the projection of the spacer 40 on the first transparent plate 31 to the edge side of the first transparent plate 31 is H2, wherein H1 > H2.

[0121] By setting H1 > H2, that is, along the first direction F1, the distance between the spacer 40 and the first connecting portion 201 of the door liner 20 is greater than the distance between the spacer 40 and the edge of the first transparent plate 31, the path of cold energy transferred from the first transparent plate 31 to the spacer 40 can be further extended, thereby effectively slowing down the speed at which cold energy is transferred to the second transparent plate 32, thus effectively avoiding the problem of condensation on the second transparent plate 32 and improving the display effect of the refrigerator 100. Of course, in some other embodiments, H1 can also be less than H2, as long as the orthographic projection of the spacer 33 on the first transparent plate 31 is offset from the first connecting portion 201 of the door liner 20.

[0122] In some embodiments, the bent portion 22 is used to connect the first transparent plate 31. The following description assumes that the bent portion 22 is configured as a first connecting portion 201:

[0123] In some embodiments, the spacer 33 is disposed near the edge of the first transparent panel 31 and at the other end away from the bending portion 22. By providing the bending portion 22 of the door liner 20 to connect the first transparent panel 31, and by making the bending portion 22 substantially parallel to the first transparent panel 31, the contact area between the first transparent panel 31 and the door liner 20 can be increased. This not only allows the bending portion 22 to support the first transparent panel 31, thereby improving the connection reliability of the first transparent panel 31 on the door liner 20, but also improves the sealing between the door liner 20 and the first transparent panel 31, ensuring that the foam material does not enter the interior of the door liner 20. At the same time, it also prevents cold air from leaking from the connection between the door liner 20 and the first transparent panel 31. In addition, the design of the bending portion 22 can further enhance the structural strength of the door liner 20.

[0124] In some embodiments, the other end of the bent portion 22 extends along the first direction F1, and the distance between the spacer 33 and the other end of the bent portion 22 along the first direction F1 is L3 (that is, the aforementioned L1), and L3 satisfies: L3≥5mm.

[0125] By setting the bending portion 22 to extend along the width direction Y or height direction Z of the door body 102, and ensuring that the distance L3 between the spacer 33 and the other end of the bending portion 22 is L3≥5mm, the path of cold air inside the refrigerator 100 from the door liner 20 through the first transparent plate 31 to the spacer 33 is further extended. This ensures that the cold air transmission path from the door liner 20 through the first transparent plate 31 to the spacer 33 is sufficiently long, thereby effectively slowing down the speed at which cold air is transmitted to the second transparent plate 32. This design not only improves the heat preservation performance of the refrigerator 100 and reduces the loss of cold air, but also ensures that the surface temperature of the second transparent plate 32 can be maintained above the dew point, effectively preventing condensation. For example, L3 can be 5mm, 6mm, 7mm, 8mm, 9mm, etc., and this embodiment does not limit this.

[0126] In some embodiments, the transparent panel assembly 30 further includes a seal 34 disposed between the first transparent plate 31 and the second transparent plate 32, and the seal 34 is disposed around the outer periphery of the spacer 40.

[0127] By providing a sealing element 34 between the first transparent plate 31 and the second transparent plate 32, the heat insulation performance of the transparent panel assembly 30 can be further enhanced, and the structural strength of the first transparent plate 31 and the second transparent plate 32 can be strengthened, providing a certain degree of protection for the transparent panel assembly 30, preventing it from being damaged by external impacts, and extending the service life of the transparent panel assembly 30.

[0128] For example, the seal 34 can be, for instance, sealant or sealing foam. These seals have good elasticity and sealing properties, effectively preventing cold air from leaking from the edges of the transparent panel assembly 30, thereby improving the insulation effect of the refrigerator 100. At the same time, the seal also prevents external moisture or dust from entering the interior of the transparent panel assembly 30, keeping the transparent panel assembly 30 clean and transparent, further enhancing the user's viewing experience.

[0129] In some embodiments, the transparent panel assembly 30 further includes a heating element 35, which is disposed around the outer periphery of the spacer 40. By distributing the heating element 35 around the outer periphery of the spacer 40, the cold air can be further blocked by the heating element 35 in the conduction path. The heat generated by the heating element 35 can compensate for the temperature drop near the second transparent plate 32 caused by the cold air transfer, so that the surface temperature of the second transparent plate 32 can be maintained above the dew point, effectively preventing condensation. In addition, the heating element 35 surrounding the outer periphery of the spacer 40 can ensure the safe and reliable operation of the heating element 35, while avoiding adverse effects on the light transmittance and overall aesthetics of the transparent panel assembly 30.

[0130] For example, the heating element 35 may be a heating element including a heating wire, a heating film, etc., and its working power and heating temperature can be adjusted according to the actual use environment and needs of the refrigerator 100 to achieve a balance between energy consumption and anti-condensation effect.

[0131] Optionally, the heating element 35 can be positioned in the middle of the insulation cavity 33a along the thickness direction X of the door body 102. If the heating element 35 is too close to the door liner 20, the heat emitted by the heating element 35 will exchange with the cold air inside the refrigerator 100, causing a loss of cold air. If the heating element 35 is too close to the second transparent plate 32, the heat generated by the heating element 35 will not have enough time to exchange with the cold air before being directly transferred to the second transparent plate 32, causing condensation to form on the second transparent plate 32. Therefore, positioning the heating element 35 in the middle of the insulation cavity 33a along the thickness direction X of the door body 102 allows the heat generated by the heating element 35 to act more evenly on the spacer 40 and the second transparent plate 32, further improving the anti-condensation effect.

[0132] In some embodiments, a temperature sensor (not shown) may also be provided on the transparent panel assembly 30 for real-time monitoring of the temperature near the second transparent plate 32. The temperature sensor can transmit the detected temperature signal to the control system of the refrigerator 100, and the control system controls the operating state of the heating element 35 according to the temperature signal to achieve precise control of the temperature of the second transparent plate 32. For example, when the temperature sensor detects that the temperature near the second transparent plate 32 is lower than the dew point temperature, the control system can start the heating element 35 to heat; when the temperature reaches or exceeds the set safe temperature, the control system can turn off the heating element 35 to avoid overheating, which could lead to increased energy consumption or safety hazards.

[0133] Please refer to it again. Figures 9 to 10A In some embodiments, the first transparent plate 31 includes multiple first transparent plates 31, and multiple first transparent plates 31 and second transparent plates 32 are sequentially spaced along the thickness direction X of the door body 102. The spacer 40 includes multiple spacers, with a spacer 40 connecting two adjacent first transparent plates 31, and a spacer 40 also connecting a second transparent plate 32 and a first transparent plate 31 adjacent to the second transparent plate 32. The heat insulation cavity 33a includes a first sub-cavity 331a and a second sub-cavity 332a. The first sub-cavity 331a is formed between the spacer 40 and two adjacent first transparent plates 31, and the second sub-cavity 332a is formed between the spacer 40 and the second transparent plate 32, and between the spacer 40 and the first transparent plate 31 adjacent to the second transparent plate 32. Both the first sub-cavity 331a and the second sub-cavity 332a are filled with argon gas.

[0134] It is understood that the embodiments shown in this application illustrate the structure of the transparent panel assembly 30 when there are two first transparent plates 31. Of course, as other embodiments, there can be three, four, five or more first transparent plates 31, etc., and the comparison of embodiments in this application is not limited. By setting multiple first transparent plates 31, the heat insulation cavity 33a is divided into a first sub-cavity 331a and a second sub-cavity 332a, and both the first sub-cavity 331a and the second sub-cavity 332a are filled with argon gas. This makes the transmission path of cold energy between the first transparent plates 31 more circuitous, prolonging the transmission path of cold energy between the first transparent plates 31, thereby further slowing down the speed at which cold energy is transferred from the inside of the refrigerator 100 to the second transparent plate 32. With the transparent panel assembly 30 formed by multiple first transparent plates 31 and second transparent plates 32, cold energy needs to undergo multiple heat conduction processes before it can be transferred from the inside of the refrigerator 100 to the second transparent plate 32. This process further reduces the total amount of cold energy transferred to the second transparent plate 32, allowing the surface temperature of the second transparent plate 32 to be better maintained above the dew point, thereby effectively preventing condensation. Furthermore, the transparent panel assembly 30, composed of multiple first transparent plates 31 and second transparent plates 32, can also improve its overall strength and stability, enhance its resistance to external impacts, and further extend the service life of the transparent panel assembly 30.

[0135] In some embodiments, the plurality of first transparent panels 31 are of the same size, and a plurality of spacers 33 are correspondingly arranged along the second direction F2. The plurality of first transparent panels 31 are spaced apart from the second transparent panels 32, and the spacers 33 between adjacent first transparent panels 31 and between adjacent first transparent panels 31 and second transparent panels 32 are correspondingly arranged along the second direction F2. This makes the cold air transfer path inside the refrigerator 100 more regular, and the cold air is less likely to become disordered during the transfer process, thereby further improving the heat preservation performance of the refrigerator 100. At the same time, the correspondingly arranged spacers 33 can also enhance the structural strength of the transparent panel assembly 30 and improve its overall stability.

[0136] Please see Figure 11 , Figure 11 This is a schematic diagram of a transparent panel assembly provided in an embodiment of this application. Figure 11 Several embodiments with different sizes of the first transparent plate are given, and Figure 11The dashed arrows in the diagram indicate the path of cold energy transfer. In other embodiments, the dimensions of multiple first transparent plates 31 and second transparent plates 32 along the first direction F1 increase sequentially along the second direction F2, and multiple spacers 40 are staggered along the second direction F2. The second direction F2 is the direction from the inside of the door frame 10 to the outside of the door frame 10. It can be seen that by setting the dimensions of multiple first transparent plates 31 and second transparent plates 32 along the first direction F1 to increase sequentially along the second direction F2, and by staggering the multiple spacers 40 along the second direction F2, the cold energy transfer path can be further extended. Simultaneously, the transfer process of cold energy between the first transparent plates 31, spacers 40, and second transparent plates 32 becomes more complex, thereby more effectively slowing down the speed at which cold energy is transferred from inside the refrigerator 100 to the second transparent plate 32, further reducing the probability of condensation on the second transparent plate 32.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the refrigerator of this application and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
