Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and more particularly to a double-door refrigerator with a sealing structure. Background Technology

[0002] Refrigerators are common household appliances. Large-capacity refrigerators usually adopt a side-by-side door design, which ensures a large internal storage space while reducing the space occupied during the opening and closing of the door.

[0003] For side-by-side refrigerators, a central vertical beam is typically installed inside the refrigerator to ensure a better seal between the door and the cabinet, allowing it to be fitted to the inside of the door with a sealing strip. However, this central vertical beam reduces the refrigerator's internal storage space, thus decreasing its internal volume. Utility Model Content

[0004] This application provides a side-by-side refrigerator with a sealing structure to solve the problem that the sealing structure of the side-by-side refrigerator door will occupy internal storage space.

[0005] On one hand, some embodiments of this application provide a double-door cabinet with a sealing structure, including a cabinet body, two doors arranged in a double-door configuration, and a first sealing assembly. The doors are hinged to the cabinet body. At least one door body is provided with a first sealing assembly, which includes a telescopic frame, a first sealing strip, a first insertion part, and a second insertion part. The first sealing strip is connected to the door body via the telescopic frame, the telescopic frame is provided with the first insertion part, and the cabinet body is provided with the second insertion part. The first and second insertion parts are for insertion and at least partially roll-fitted. When the two doors close the cabinet and are in a closed state, the second insertion part is inserted into the first insertion part, causing the telescopic frame to extend towards the other door body and sealingly connecting the first sealing strip between the two doors.

[0006] Optionally, one of the first and second plug-in portions is a roller structure or a ball structure. The other of the first and second plug-in portions is a plug-in component corresponding to the former.

[0007] Optionally, the first insertion part is a roller, which is rotatably connected to the telescopic frame. The second insertion part is a connector, one end of which is connected to the cabinet body, and when the door is closed, the other end of the second insertion part is inserted and adapted to the first insertion part.

[0008] Optionally, the connector has a chamfered or rounded surface at the position where it contacts the roller structure or ball structure.

[0009] Optionally, there are two first connectors, with one first connector spaced apart from each end of the telescopic frame along its length. There are at least two second connectors, with one second connector used to connect to and fit one first connector.

[0010] Optionally, there are two first sealing components, with one first sealing component provided for each of the two doors of the double-door structure. When the two doors are in the closed state, the first and second insertion parts are inserted and adapted to each other, so that the telescopic bracket connected to the door extends toward the other door, and the two first sealing strips at least partially contact and adhere to each other.

[0011] Optionally, when both doors are closed, they are spaced apart along their width. The first sealing assembly also includes at least two limiting members and at least two elastic members. Along the width direction, the telescopic plate frame has at least two limiting holes, one limiting member is inserted into one limiting hole, and one end of the limiting member is connected to the door. One elastic member is correspondingly provided with one limiting member. Along the width direction, the other end of the limiting member is compressed between the elastic member and the telescopic plate frame, causing the telescopic plate frame to retract towards the connected door. When both doors are closed, the first insertion part and the second insertion part are inserted into each other, extending along the width direction to move the telescopic plate frame away from the connected door and compressing the elastic member.

[0012] Optionally, along the width direction, a positioning groove is provided at the end of the door body away from the hinge position, and the telescopic plate frame is inserted into the positioning groove. When the door body is in the closed state, the side of the door body facing the cabinet is the inner side, and the inner side wall of the door body is provided with a plug-in hole communicating with the positioning groove. The first plug-in part is located in the positioning groove, and the second plug-in part is used to plug into and adapt to the first plug-in part through the plug-in hole.

[0013] Optionally, the first sealing assembly further includes a magnetic strip, with one or more magnetic strips located within a first sealing strip.

[0014] Optionally, the double-door cabinet with a sealing structure further includes a second sealing assembly, which includes two positioning members and two second sealing strips. Along the length of the telescopic frame, the two positioning members are spaced apart and connected to the cabinet body. One second sealing strip is connected to one positioning member. Along the length of the telescopic frame, the second sealing strip is connected to the side of the positioning member facing the telescopic frame, and when the door is closed, the second sealing strip contacts the end of the telescopic frame.

[0015] On the other hand, some embodiments of this application also provide a refrigerator, including a double-door cabinet with a sealing structure as described above and a refrigeration circuit, the refrigeration circuit being used to cool the internal space of the cabinet.

[0016] The technical solutions provided in this application have the following advantages compared with the prior art:

[0017] By setting the first sealing component, when the door moves to the closed state to seal the internal space of the cabinet, the first and second plug-in parts are plugged in and adapted, so that the second plug-in part drives the connected telescopic plate to extend and move towards the other door, and drives the first sealing strip to contact or fit with the other door or other sealing structure, thereby sealing and filling the gap between the two doors, so that the double door structure can achieve a better sealing effect on the internal space of the cabinet when closed.

[0018] During the process of the door opening from the closed state, the first and second plug-in parts disengage from the plug-in adaptation state, so that the telescopic frame no longer bears the force of moving towards the extended position, and the first sealing strip can retract away from the other door body without hindering the opening process of the door body.

[0019] Compared to related technologies that involve installing a central vertical beam within the cabinet, the first sealing component provided in this application only needs to be installed at the door, without occupying additional space within the cabinet, thus increasing the internal storage space. Furthermore, since the first and second insertion parts at least partially roll during the insertion process, they exhibit lower insertion resistance, making the door easier to close and open.

[0047] Please see Figures 1 to 14 This application provides a side-by-side refrigerator with a sealing structure to solve the problem that the sealing structure of the side-by-side refrigerator door will occupy internal storage space.

[0048] like Figure 1 and Figure 2 As shown, the refrigerator includes a double-door cabinet with a sealing structure (hereinafter referred to as the double-door cabinet 100). The double-door cabinet 100 includes a cabinet 110 and at least two doors 120. The doors 120 are hinged to the cabinet 110, and two of the doors 120 are arranged in a double-door structure for opening or closing the internal space (i.e., storage compartment) inside the cabinet 110.

[0049] Combination Figure 3The refrigerator also includes a refrigeration circuit 200, which comprises a compressor 210, a condenser 220, a throttling device 230, an evaporator 240, and the compressor 210 connected in sequence. The compressor 210 compresses the refrigerant and provides power, causing the refrigerant to liquefy and release heat in the condenser 220. After the liquefied refrigerant is depressurized by the throttling device 230, it absorbs heat and vaporizes in the evaporator 240. The vaporized refrigerant finally enters the compressor 210 through the return port to be circulated and compressed.

[0050] Thus, by setting up fans and air ducts to drive air to circulate between the evaporator 240 and the internal space of the cabinet 110, air is used to cool the storage compartments, thereby forming an air-cooled refrigerator. Depending on the amount of air circulation and the cooling effect of different evaporators 240, storage compartments with multiple temperature ranges, such as refrigerator compartments, freezer compartments, soft-freeze compartments, and variable temperature compartments, can be formed.

[0051] Alternatively, the evaporator 240 can be configured as a coil structure, and the coil structure can be located on the side wall of the storage compartment, or the coil structure can be located inside the storage compartment, so that the storage compartment is directly cooled by the refrigerant that evaporates and vaporizes in the coil structure, thereby forming a direct-cooling refrigerator.

[0052] For example, in the double-door cabinet 100, the double-door structure can be provided only at the opening of one of the storage compartments. Figure 1 As shown, the storage compartment above the cabinet 110 has a double door structure, and the two storage compartments below the cabinet 110 can be set as single-leaf hinged door structures or sliding drawer structures.

[0053] Alternatively, the cabinet 110 may include two storage compartments spaced apart, with the upper storage compartment having a double-door structure and the lower storage compartment also having a double-door structure, such as a refrigerator with a cross-door structure.

[0054] like Figure 4 As shown, the double-door housing 100 also includes a first sealing assembly 130, and at least one door 120 is provided with the first sealing assembly 130. Combined with... Figure 5 and Figure 6 The first sealing assembly 130 includes a telescopic plate frame 131, a first sealing strip 132, and a first insertion part 133. The first sealing strip 132 is connected to the door body 120 via the telescopic plate frame 131, and the telescopic plate frame 131 is provided with the first insertion part 133. (See reference...) Figure 7 and Figure 8 The cabinet 110 is provided with a second plug-in portion 134, and the first plug-in portion 133 and the second plug-in portion 134 are used for plugging and at least partially rolling adaptation.

[0055] Among them, such as Figure 8As shown, when the two doors 120 close the cabinet 110 and are in a closed state, the second plug-in part 134 is plugged into and adapted to the first plug-in part 133, so that the telescopic plate frame 131 extends toward the other door 120 and the first sealing strip 132 is sealed between the two doors 120.

[0056] Thus, by setting the first sealing component 130, when the door 120 moves to the closed state to close the internal space of the cabinet 110, the first plug-in part 133 and the second plug-in part 134 are plugged in and adapted, so that the second plug-in part 134 drives the connected telescopic plate frame 131 to extend and move towards the other door 120, and drives the first sealing strip 132 to contact or adhere to the other door 120 or other sealing structure, thereby sealing and filling the gap between the two doors 120, so that the door 120 of the double door structure can achieve a better sealing effect on the internal space of the cabinet 110 when closed.

[0057] During the process of the door 120 moving from the closed state to the open state, the first plug-in part 133 and the second plug-in part 134 disengage from the plug-in adaptation state, so that the telescopic plate 131 no longer bears the force of moving towards the extended position, and the first sealing strip 132 can retract in a direction away from the other door 120 without hindering the opening process of the door 120.

[0058] Compared to related technologies that involve installing a central vertical beam within the cabinet 110, the first sealing component 130 provided in this application only needs to be installed at the door 120, without occupying additional space within the cabinet 110, thus increasing the internal storage space of the cabinet 110. Furthermore, since the first insertion part 133 and the second insertion part 134 undergo at least partial rolling adaptation during the insertion process, they exhibit lower insertion resistance, making the door 120 easier to close and open.

[0059] Between two door bodies 120 with a double-door structure, a first sealing assembly 130 can be installed on the side of one of the door bodies 120 away from the hinge axis. When both door bodies 120 are closed, the extended telescopic plate frame 131 drives the first sealing strip 132 to contact and adhere to the side wall of the other door body, thereby sealing the gap between the two door bodies 120. The structure is simple and has a good sealing effect.

[0060] Or, such as Figure 7 and Figure 8As shown, there are two first sealing components 130, with one first sealing component 130 provided for each of the two door bodies 120 of the double-door structure. When the two door bodies 120 are in the closed state, the first insertion part 133 and the second insertion part 134 are inserted and adapted to each other, so that the telescopic plate frame 131 connected to the door body 120 extends toward the other door body 120, and the two first sealing strips 132 at least partially contact and adhere to each other, so that the gap between the two door bodies 120 has a good sealing effect.

[0061] It should be noted that, since the first sealing assembly 130 is installed on the side of both door bodies 120 away from the hinge axis, the extension and retraction of the telescopic plate 131 can be adjusted so that the two door bodies 120 closing sequentially are not obstructed by the protruding first sealing strip 132 and the telescopic plate 131.

[0062] If one of the doors 120 can be closed first, the extended first sealing strip 132 will not obstruct the closing action of the other door 120 when that door 120 is in the closed state. When the other door 120 rotates to the closed state, the second extended first sealing strip 132 will extend along the width direction of the door 120 and approach the first first sealing strip 132 until the two come into contact and fit together, thus sealing the gap between the two doors 120. Similarly, when opening the doors 120, either the left or right door 120 can be opened first, which is convenient and quick.

[0063] In other words, the first sealing component 130 provided in this application can be installed on each of the two door bodies 120 of the double door structure. During the opening and closing of the door bodies 120, the opening or closing sequence of the door bodies 120 can be adjusted arbitrarily without affecting the sealing effect between the two door bodies 120, thus providing a better user experience.

[0064] To reduce the insertion resistance between the first insertion portion 133 and the second insertion portion 134, one of the first insertion portion 133 and the second insertion portion 134 can be configured as a roller structure or a ball structure. The other of the first insertion portion 133 and the second insertion portion 134 is a corresponding insertion member. This ensures that during the insertion process, the contact surfaces of the first insertion portion 133 and the second insertion portion 134 experience rolling friction rather than sliding friction, resulting in a smoother insertion process and lower insertion resistance.

[0065] For example, such as Figure 5 and Figure 6 As shown, the first insertion part 133 is a roller, and the first insertion part 133 is rotatably connected to the telescopic frame 131. Correspondingly, as... Figure 8As shown, the second plug-in part 134 is a plug-in component. One end of the second plug-in part 134 is connected to the cabinet body 110. When the door body 120 is in the closed state, the other end of the second plug-in part 134 is plugged into and adapted to the first plug-in part 133.

[0066] The first insertion portion 133 of the roller structure provides rolling resistance to the second insertion portion 134, and features a simple structure that facilitates rotational connection and installation. Furthermore, the first insertion portion 133 and the second insertion portion 134 of the roller structure have a large contact area, which helps improve the stability of their insertion and adaptation structure.

[0067] Since the first insertion part 133 of the roller structure is a movable part, by setting the first insertion part 133 to be connected to the telescopic plate frame 131, the first insertion part 133 can be hidden in the installation space between the telescopic plate frame 131 and the door body 120, so as to reduce the collision interference of the external structure and have better stability.

[0068] Taking the example of the telescopic bracket 131 extending outward along the width direction of the door 120 (i.e., away from the hinge axis of the door 120) when the door 120 is in the closed state, and the telescopic bracket 131 moving inward along the width direction (i.e., closer to the hinge axis of the door) when the door 120 is opened from the closed state.

[0069] During the closing process of the door 120, the second plug-in part 134 gradually plugs into and adapts to the first plug-in part 133, and applies a force and displacement outward along the width direction of the door 120 to the first plug-in part 133, so that the telescopic plate frame 131 drives the first sealing strip 132 to move outward and extend.

[0070] During the opening of the door 120, the second plug-in part 134 and the first plug-in part 133 gradually disengage, so that the force and displacement of the second plug-in part 134 acting on the first plug-in part 133 to move outward are reduced, that is, the telescopic plate frame 131 and the first sealing strip 132 move inward and retract.

[0071] like Figure 8 As shown, at the end of the second connector 134 furthest from the cabinet 110, that is, at the end where the second connector 134 contacts the first connector 133, a chamfered surface or a rounded corner surface can be provided. In other words, the position where the connector contacts the roller structure or ball structure has a chamfered surface or a rounded corner surface.

[0072] Thus, the chamfered or rounded surface of the second insertion part 134 makes the contact process with the first insertion part 133 smoother, which helps to reduce the resistance during the insertion and fitting process.

[0073] There are two first connectors 133, one of which is connected to each end of the telescopic frame 131 along its length. The length of the telescopic frame 131 is the same as the height of the cabinet 110 or the door 120. Correspondingly, there are two second connectors 134, one of which is used to connect and fit one first connector 133.

[0074] Taking the telescopic frame 131 as an example where its length is vertical, each end of the telescopic frame 131 is connected to a first insertion part 133. Furthermore, the cabinet 110 has a second insertion part 134 corresponding to the two side walls at the opening, so that the two second insertion parts 134 and the two first insertion parts 133 can be inserted and fitted one-to-one. When the door 120 is closed, the upper and lower ends of the telescopic frame 131 can be evenly stressed, increasing the contact area of ​​the first sealing strip 132 and thus improving the sealing effect between the two doors 120.

[0075] like Figure 7 As shown, when the two doors 120 are in the closed state, the two doors 120 are spaced apart along the width direction (i.e., the X direction) of the doors 120.

[0076] In order to prevent the continuously extending telescopic plate 131 and the first sealing strip 132 from affecting the smoothness of opening and closing of the door 120 after the first plug-in part 133 and the second plug-in part 134 are disengaged from the plug-in adaptation state.

[0077] like Figure 6 and Figure 9 As shown, the first sealing assembly 130 also includes at least two limiting members 135 and at least two elastic members 136. Along the width direction X, the telescopic frame 131 is provided with at least two limiting holes 137. One limiting member 135 is inserted into and adapted to one limiting hole 137, and one end of the limiting member 135 is connected to the door body 120. One elastic member 136 is correspondingly provided with one limiting member 135. Along the width direction X, the other end of the limiting member 135 is compressed between the elastic member 136 and the telescopic frame 131, so that the telescopic frame 131 moves and retracts towards the connected door body 120.

[0078] Among them, reference Figure 8 and Figure 9 When the two doors 120 are in the closed state, the first plug-in part 133 and the second plug-in part 134 are plugged in and adapted to each other, so that the telescopic frame 131 moves and extends away from the connected door 120 along the width direction X, and compresses the elastic member 136.

[0079] Thus, when the door 120 is rotated open to disengage from the closed state, the first plug-in part 133 and the second plug-in part 134 disengage from the plug-in adaptation state.

[0080] Combination Figure 6 and Figure 10 At this time, under the action of the elastic element 136 in the compressed state, a force is provided to the telescopic plate 131 to move and retract toward the connected door body 120, so that the telescopic plate 131 drives the first sealing strip 132 to move and retract, thereby avoiding the exposure of the extended telescopic plate 131 and the first sealing strip 132, and also not hindering the opening and closing rotation of the door body 120.

[0081] To further improve the sealing effect between the two door panels 120, such as Figure 5 and Figure 6 As shown, along the width direction X, a positioning groove 121 is provided at the end of the door body 120 away from the hinge position, and the telescopic plate frame 131 is inserted into the positioning groove 121. (Refer to...) Figure 8 and Figure 11 When the door 120 is closed, the side of the door 120 facing the cabinet 110 is the inner side, and the inner wall of the door 120 is provided with a plug hole 122 that connects to the positioning groove 121. The first plug part 133 is located in the positioning groove 121, and the second plug part 134 is used to plug and adapt to the first plug part 133 through the plug hole 122.

[0082] A positioning groove 121 is provided on the door body 120, and the telescopic frame 131 is disposed within the positioning groove 121. For example... Figure 8 As shown, when the telescopic frame 131 is in the extended state, the telescopic frame 131 is in contact with the inner and outer side walls of the positioning groove 121 to improve the sealing effect between the door body 120 and the telescopic frame 131, thereby improving the overall sealing effect between the door bodies 120.

[0083] The elastic element 136 can be a spring or other elastic structure capable of accumulating elastic potential energy, and there is no limitation on this.

[0084] The telescopic frame 131 is an integrally formed strip-shaped structure or plate-shaped structure. Along the width direction X, the side of the telescopic frame 131 connected to the first sealing strip 132 is provided with a snap-fit ​​groove, which is used to insert and snap the first sealing strip 132. If the first sealing strip 132 is provided with an insertion part that fits into the snap-fit ​​groove, the insertion part of one end of the first sealing strip 132 can be inserted into the insertion groove along the length direction of the snap-fit ​​groove, and the first sealing strip 132 can be inserted into the snap-fit ​​groove along the length direction to complete the assembly of the first sealing strip 132 and the telescopic frame 131.

[0085] In addition, the snap-fit ​​groove can also accommodate the protruding part of the limiting member 135 and the elastic member 136, and the first sealing strip 132 seals the snap-fit ​​groove to prevent the limiting member 135 and the elastic member 136 from being exposed, which has a better decorative effect and aesthetics.

[0086] In some embodiments, such as Figure 6 and Figure 8 As shown, the first sealing assembly 130 also includes a magnetic strip 138, and one or more magnetic strips 138 are provided in a first sealing strip 132.

[0087] When the door 120 is in the closed state, when the first sealing strip 132 extends and contacts another first sealing strip 132 or the side wall of the door 120, the magnetic attraction force of one or more built-in magnetic strips 138 increases the contact area between the two first sealing strips 132 or between the first sealing strip 132 and the side wall of the door 120, thereby further improving the sealing effect between the two door 120s.

[0088] In some embodiments, such as Figure 12 and Figure 13 As shown, the double-door cabinet 100 also includes a second sealing assembly 140, which includes two positioning members 141 and two second sealing strips 142. Along the length of the telescopic frame 131, the two positioning members 141 are spaced apart and connected to the cabinet body 110. One second sealing strip 142 is connected to one positioning member 141. Along the length of the telescopic frame 131, the second sealing strip 142 is connected to the inner sides of the two positioning members 141 that are close to each other. When the door 120 (as shown) Figure 8 When the second sealing strip 142 is in the closed state (as shown), it contacts the end of the telescopic frame 131.

[0089] The second connector 134 can be directly connected to the cabinet 110. Or, as... Figure 12 and Figure 13 As shown, the second connector 134 can also be connected to the cabinet 110 via the positioning member 141, that is, the second connector 134 is fixed to the positioning member 141. When connecting the positioning member 141 and the cabinet 110, they can be connected by rivets or by screws, and there is no limitation on this.

[0090] When the two double-door structures 120 are in the closed state, such as Figure 5 and Figure 14 As shown, since there is a gap between the telescopic frame 131 and the first sealing strip 132 and the frame of the cabinet 110, the second sealing component allows the second sealing strip 142 to contact the upper and lower end faces of the telescopic frame 131 for sealing and filling, thereby reducing or eliminating the gap between them, so that the cabinet 110 and the two doors 120 have a better sealing effect, and the interior of the cabinet 110 has better airtightness.

[0091] Taking the side-by-side cabinet 100 as an example in a refrigerator, the gap between the door 120 and the cabinet 110 is filled by the first sealing component 130 and the second sealing component 140 to improve the sealing effect. This can reduce or avoid the leakage of cold air inside the cabinet 110, which is energy-saving and environmentally friendly. It can also solve the problem of condensation caused by cold air at the leakage location, resulting in a better user experience.

[0092] It should be noted that the double-door cabinet 100 provided in this application embodiment can be adapted to the refrigeration circuit 200 to achieve refrigeration or freezing, thereby meeting the purpose of low-temperature storage of items. Alternatively, the double-door cabinet 100 can also be applied to structures or devices with sealing requirements such as cabinets, wardrobes, or dishwashers, and there is no limitation thereto.
