Description

Technical Field

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

[0002] For refrigerators with electronic components (such as a display screen or voice interaction module) on the door that can open from the left or right, the cabinet and the door need to be connected through the door hinge hole to connect the wires inside the door and the wires inside the cabinet. This enables communication between the cabinet and the door, allowing users to interact on the display screen or control and adjust the refrigerator through voice.

[0003] In order to facilitate the connection of wires between the door and the box, related technologies typically have a first connector for the wires inside the box and a second connector for the wires inside the door. The first and second connectors are plugged into each other to achieve the connection of wires between the door and the box.

[0004] However, in related technologies, the door hinge hole on the door body needs to be designed to allow the door body to rotate. Therefore, the door hinge hole on the door body is usually round, while the second connector is usually square. Moreover, the size of the second connector is usually relatively large. So, in order to ensure that the second connector can pass smoothly through the door hinge hole and connect with the first connector, the door hinge hole usually needs to be designed to be relatively large. This can easily lead to a relatively thick door body, which is not conducive to the miniaturization design of the refrigerator. Utility Model Content

[0005] This application discloses a refrigerator that can achieve electrical connection between the door and the cabinet while taking into account both miniaturization and interchangeable left and right door opening, thus realizing the intelligent design of the refrigerator.

[0006] To achieve the above objectives, this application discloses a refrigerator, which includes:

[0007] The box has a storage room inside, and the box has a first opening communicating with the storage room on its side in the depth direction. The box also has two cable outlet holes on its top in the height direction, and the two cable outlet holes are located on both sides of the box in the width direction.

[0008] A door body, which is rotatably connected to the housing, and the door body is configured to open or close the first opening;

[0009] The upper end cover is disposed at the top of the door body in the height direction of the box body, and the upper end cover is provided with shaft holes on both sides in the width direction of the box body, which are respectively through the height direction of the box body.

[0010] Two sets of hinge assemblies are detachably mounted on the top of the housing in its height direction and respectively cover the two cable outlet holes. Each hinge assembly has a cable passage space communicating with the cable outlet hole. Each hinge assembly also has a pivot that is detachably rotatably inserted into the pivot hole. The pivot has a cable passage hole extending along the height direction of the housing, communicating with both the pivot hole and the cable passage space.

[0011] Two sets of connecting wire assemblies, each of the connecting wire assemblies comprising:

[0012] A first connecting line is disposed inside the housing, and one end of the first connecting line is connected to a first connector, which passes through the outlet hole and is located outside the housing; and...

[0013] The second connecting line is disposed inside the door body, and one end of the second connecting line is connected to a second connector. The second connecting line passes through the wire hole and the shaft hole, and the second connector is located in the wire space and is detachably connected to the first connector.

[0014] The second connector is square in shape. The upper end cover is provided with square through holes on both sides of the box in the width direction and in the height direction of the box. The square through holes and the shaft hole are arranged in the width direction of the box, and a communication opening is provided between the square through holes and the shaft hole. The hole wall of the wire hole is provided with a notch.

[0015] The second connector can pass through the square through hole located outside the door body, the second connecting wire can enter the shaft hole from the communication port through the square through hole, and the second connecting wire can enter the wire hole from the notch.

[0016] In the refrigerator provided in this application embodiment, by utilizing the cooperation of two sets of detachable hinge assemblies and two sets of connecting wire assemblies, when the user needs to open the door on the left, the hinge assembly is installed on the right side, and the first and second connecting wires of the right connecting wire assembly are connected and conductive through the first and second connectors, while the hinge assembly is not installed on the left side, and the first and second connecting wires of the left connecting wire assembly are separated; similarly, when the user needs to open the door on the right, the hinge assembly is installed on the left side, and the first and second connecting wires of the left connecting wire assembly are connected and conductive through the first and second connectors, while the hinge assembly is not installed on the right side, and the first and second connecting wires of the right connecting wire assembly are separated. This provides the refrigerator with two interchangeable assembly modes for opening the left and right doors, and can achieve the design of interchangeable opening of the left and right doors of the refrigerator while ensuring that the cabinet and the door maintain electrical connection.

[0017] Based on the above design, square through holes are provided on the left and right sides of the upper cover. These square through holes and shaft holes are arranged along the width direction of the housing, and a connecting port is provided between the square through holes and the shaft holes. The wall of the wire hole has a notch, so that the second connector can pass through the square through hole and be located outside the door. After the second connector passes through, the second connecting wire is moved through the connecting port and enters the shaft hole, so that the second connecting wire returns to the shaft hole. The second connecting wire can also enter the wire hole through the notch to enter the wire passage space of the hinge assembly and connect with the first connector, thereby realizing the electrical connection between the door and the housing. This avoids the need to open a large shaft hole in the upper cover for the second connector to pass through. Thus, without increasing the thickness of the door, the second connecting wire can be passed through the shaft hole and the wire hole, and the second connector can be located in the door and connect with the first connector to realize the electrical connection between the door and the housing.

[0018] As an optional implementation, in the embodiments of this application, the upper end cover is provided with two elliptical protrusions on both sides of the box body in the width direction. Both elliptical protrusions are located inside the door body, and each elliptical protrusion is respectively arranged around the periphery of the shaft hole and the square through hole. Each elliptical protrusion is used for wrapping and pasting with sealing tape to seal the shaft hole and the square through hole, thereby effectively preventing the foam material inside the door body from leaking out from the shaft hole and the square through hole, thus preventing the leakage of foam material inside the door body, thereby effectively reducing the occurrence of door body leakage and ensuring the yield rate of the door body.

[0019] Because the outer periphery of the elliptical boss is relatively smooth and rounded, it is easy to apply sealing tape (such as masking tape), avoiding dead corners that could affect the sealing performance of the sealing tape on the square through holes and shaft holes. This effectively prevents the foam material inside the door from leaking out through the shaft holes and square through holes, thus reducing the occurrence of foam leakage and ensuring a higher yield rate. Moreover, the elliptical boss occupies less space than a circular boss, especially in the depth direction of the housing. This makes it suitable for top covers with a relatively small thickness in the depth direction of the housing, which is beneficial for achieving a thinner and lighter door design.

[0020] As an optional implementation, in an embodiment of this application, the upper end cover is provided with a first receiving groove on each side of the housing in the width direction, the opening of the first receiving groove is facing upward, the square through hole is formed on the bottom wall of the first receiving groove, and the first receiving groove is used to receive the second connector and the second connecting wire.

[0021] The refrigerator also includes two first covers, which are detachably fitted onto the two first receiving slots.

[0022] With this configuration, when the user needs to open the door from the left, the second connecting wire and the second connector on the left are stored in the first receiving slot on the left, and a first cover is installed in the first receiving slot on the left to prevent the second connecting wire, the second connector, and the square through hole on the left from being exposed. The hinge assembly is installed in the first receiving slot on the right, and a first cover is installed in the first receiving slot on the right to prevent the square through hole on the right from being exposed. Similarly, when the user needs to open the door from the right, the hinge assembly is installed in the second mounting slot on the left, and the second connecting wire and the second connector on the right are stored in the first receiving slot on the right, and a first cover is installed in the first receiving slot on the right to prevent the second connecting wire, the second connector, and the square through hole on the right from being exposed. That is, this application can install the hinge assembly on one side while using the first cover on the other side to cover the first receiving slot and cover the square through hole. This can prevent the second connecting wire and the second connector from being exposed, prevent dust, protect the second connecting wire and the second connector, and also help improve the product appearance integrity and aesthetics of the refrigerator.

[0023] As an optional implementation, in the embodiments of this application, the interior of the housing is provided with a square boss, which surrounds the periphery of the outlet hole, and the diagonal corners of the square boss are rounded. The square boss is used for wrapping and pasting with sealing tape to seal the outlet hole, thereby effectively preventing the foam material inside the housing from leaking out from the outlet hole, thus preventing leakage of the foam material inside the housing, and effectively reducing the occurrence of foam leakage in the housing, ensuring the yield rate of the housing.

[0024] Because the square boss has rounded corners at the opposite corners, its outer perimeter is smooth and easy to apply sealing tape (such as masking tape), avoiding dead corners that could affect the sealing performance of the tape to the cable outlet. This effectively prevents the foam material inside the box from leaking out through the cable outlet, thus reducing the occurrence of foam leakage and further ensuring the yield rate of the box.

[0025] As an optional implementation, in an embodiment of this application, the housing is provided with two second receiving slots at the top in the height direction, the opening of each second receiving slot is facing upward, and the two second receiving slots are respectively located on both sides of the housing in the width direction. The cable outlet is formed on the bottom wall of the second receiving slot, and the second receiving slot is used to receive the first connector and the first connecting wire.

[0026] The refrigerator also includes two second covers, which are detachably fitted onto the two second receiving slots.

[0027] This configuration, utilizing two hinge assemblies and two second covers, allows the first connecting wire and first connector on the left side to be stored in the second receiving slot on the left side when the user needs to open the door from the left. A second cover is then installed in the second receiving slot on the left side to prevent the first connecting wire, first connector, and cable outlet from being exposed. The hinge assembly is installed in the second receiving slot on the right side. Similarly, when the user needs to open the door from the right side, the hinge assembly is installed in the first receiving slot on the left side, and the first connecting wire and first connector on the right side are stored in the second receiving slot on the right side. A second cover is then installed in the second receiving slot on the right side to prevent the first connecting wire, first connector, and cable outlet from being exposed. In other words, this application allows for the simultaneous installation of a hinge assembly on one side and the use of a second cover on the other side to close and seal the second receiving slot, thereby closing and sealing the cable outlet. This not only achieves waterproofing and dustproofing, ensuring the quality and performance of the refrigerator, but also prevents the first connecting wire and first connector from being exposed, thus improving the product's appearance integrity and aesthetics.

[0028] As an optional implementation, in an embodiment of this application, the housing includes:

[0029] The container body, the storage compartment and the first opening are both formed in the container body, and the container body has two second openings at its top in the height direction, the two second openings communicating with the interior of the container body, and the two second openings being located on both sides of the container body in the width direction; and,

[0030] Two receiving boxes are disposed inside the main body of the box. Two second receiving slots are formed on the two receiving boxes respectively, and the openings of the two second receiving slots are respectively connected to two second openings. Two second covers are respectively detachably closed to the two second openings.

[0031] This design is equivalent to thickening a portion of the cabinet, forming a second receiving groove at the thickened area to accommodate the first connecting wire and the first connector. Compared to making the entire cabinet thicker, forming the second receiving groove directly on the cabinet reduces the weight of the cabinet and the refrigerator. In other words, the design structure described above can conceal the first connecting wire and the first connector, improving the integrity and aesthetics of the refrigerator's appearance while making the refrigerator lighter, thus meeting the requirements for lightweight design.

[0032] As an optional implementation, in an embodiment of this application, the box further includes two sealing rings, which abut against the inner wall surfaces of the two receiving boxes and the main body of the box, respectively.

[0033] This design allows for the use of a sealing ring to seal the connection between the housing and the main body of the box, preventing the foam material inside the box from leaking out from the connection. This effectively reduces the occurrence of foam leakage and ensures a high yield rate for the boxes.

[0034] As an optional implementation, in an embodiment of this application, the second receiving groove has a first hook protruding from its groove wall. The first hook extends axially along the outlet hole and passes through the second opening to the outside of the box body, and abuts against the outer top surface of the box body to fix the receiving box to the box body.

[0035] This design allows the containment box to be fixed to the main body of the container by snap-fit, making the connection simple and facilitating the assembly of the containment box and the main body of the container.

[0036] As an optional implementation, in an embodiment of this application, one of the groove wall of the second receiving groove and the second cover is provided with a slot, and the other of the groove wall of the second receiving groove and the second cover is provided with a second hook, which engages with the slot.

[0037] With this design, the storage box can provide a snap-fit ​​point for the second cover, allowing the second cover to be fixed to the main body of the box by snap-fit. The connection method is relatively simple and facilitates the assembly between the second cover and the main body of the box.

[0038] As an optional implementation, in the embodiments of this application, each of the hinge components includes:

[0039] A first hinge member, detachably disposed at the top of the housing in its height direction, and the pivot shaft disposed on the first hinge member; and,

[0040] The second hinge component is separately disposed from the first hinge component and is detachably connected to the top of the housing. The second hinge component covers the first hinge component, the wire passage hole and the wire outlet hole, and the wire passage space is formed between the second hinge component and the first hinge component.

[0041] With this configuration, during assembly, the first hinge component can be fixed to the housing first, allowing the first connecting wire to pass through the shaft hole and the wire guide hole. The first connector and the second connector are positioned above the first hinge component for insertion. Then, the second hinge component is fixed to the housing, covering the first hinge component, the wire guide hole, and the wire outlet hole, placing the first connector and the second connector within the wire guide space. This makes the insertion of the first and second connectors visible and easy to perform. During disassembly, the second hinge component can be removed first, exposing the first and second connectors, thus facilitating their separation. Attached Figure Description

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0067] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application 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 application.

[0068] The terms "first," "second," etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first connecting line may be referred to as a second connecting line, and similarly, a second connecting line may be referred to as a first connecting line. Both the first connecting line and the second connecting line are connecting lines, but they are not the same connecting line.

[0069] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0070] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection between two components.

For example, A and / or B can mean: A alone, A and B together, or B alone. That is, the term "and / or" as used in this specification includes any and all combinations of the related listed items.

[0073] As society develops and people's living standards improve, the pace of life becomes faster and faster. As a result, people are more willing to buy a lot of food and store it in the refrigerator. The refrigerator has become one of the indispensable household appliances in people's daily lives.

[0074] However, most refrigerators on the market today use a single-side door design, meaning they can only open from the left or right side, and consumers cannot change the opening direction of the refrigerator door according to their needs.

[0075] However, due to limitations in the location where consumers can place their refrigerators, space constraints in cabinets during renovations, and different usage habits, the opening direction of the refrigerator needs to be adjusted according to consumer needs. Therefore, it is essential for refrigerators to have the function of accommodating both left- and right-opening doors to meet the actual needs of different consumers regarding the opening direction of the refrigerator door.

[0076] With the development of technology, the intelligentization of refrigerators has become a key direction for refrigerator development and a focus of research and development for many refrigerator manufacturers. Many users' requirements for refrigerators go beyond basic food storage and preservation functions; they increasingly demand intelligent operation that facilitates daily life and improves quality of life. To achieve intelligent refrigerators, electronic components such as touch screens and voice interaction modules are typically installed on the refrigerator door to realize these functions.

[0077] For refrigerators with electronic components on the door that can open from the left or right, the door hinge hole is needed as a channel to connect the wires inside the door and the wires inside the refrigerator. This enables communication between the door and the refrigerator, allowing users to interact with the display screen or control and adjust the refrigerator via voice.

[0078] In order to facilitate the connection of wires between the door and the box, related technologies typically have a first connector for the wires inside the box and a second connector for the wires inside the door. The first and second connectors are plugged into each other to achieve the connection of wires between the door and the box.

[0079] However, in related technologies, the hinge holes on the door body need to allow for door rotation, so these holes are usually circular. Since the door body is typically thin, the space for the hinge holes is limited, resulting in a small hole diameter. The second connector, on the other hand, is usually square, and its size is generally larger than the hinge hole diameter, preventing it from passing through directly. Therefore, to ensure the second connector can smoothly pass through the hinge hole and connect with the first connector, the hinge hole usually needs to be designed to be relatively large. This often results in a thicker door body, which is detrimental to the miniaturization design of the refrigerator.

[0080] In view of this, the present application provides a refrigerator that can achieve electrical connection between the door and the cabinet while taking into account both miniaturization and interchangeable left and right door opening designs.

[0081] The technical solutions of some 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.

[0082] Please see Figure 1 , Figure 1 This is a schematic diagram of an exemplary refrigerator provided in an embodiment of this application, wherein the refrigerator 100 is a single-door refrigerator.

[0083] The refrigerator provided in this application embodiment includes a cabinet 11, which forms the overall appearance of the refrigerator 100. The cabinet 11 can be a columnar structure, such as a circular columnar structure, an elliptical columnar structure, a square columnar structure, etc., and the cabinet 11 has a depth direction f1, a width direction f2, and a height direction f3.

[0084] like Figure 1 and Figure 2 As shown, the box 11 has a front side and a rear side arranged opposite to each other. The side of the box 11 facing the user is the front side of the box 11, and the distance from the rear side to the front side of the box 11 is the depth direction f1 of the box 11. The box 11 also has a left side and a right side arranged opposite to each other. The distance from the left side to the right side of the box 11 is the width direction f2 of the box 11. The box 11 also has a top and a bottom arranged opposite to each other. The distance from the bottom to the top of the box 11 is the height direction f3 of the box 11.

[0085] Among the three directions of box 11, namely depth direction f1, width direction f2, and height direction f3, two of them are perpendicular or approximately perpendicular.

[0086] Understandably, during the production process, process factors such as equipment precision and measurement errors may affect the actual molding effect of the box 11, making the box 11 "approximately perpendicular" in the degree direction f1, width direction f2 and height direction f3. That is, the included angle between the degree direction f1, width direction f2 and height direction f3 can be approximately 90°, such as 88°, 89°, 91° or 92°.

[0087] In some embodiments, the interior of the housing 11 is provided with a storage compartment 111, which is mainly used for storing items such as food. The storage compartment 111 can be a refrigerator compartment, a freezer compartment, or a variable temperature compartment. The temperature of the refrigerator compartment is typically between 2°C and 8°C, keeping food in a refrigerated state. The temperature of the freezer compartment is typically between -26°C and -14°C, keeping food in a frozen state. The temperature of the variable temperature compartment is generally adjustable between -7°C and 5°C, or can be directly adjusted to -26°C to -14°C, for example, -17°C, for use as a freezer compartment.

[0088] In some embodiments, the cabinet 11 has a first opening 112 communicating with the storage compartment 111 on one side in the depth direction f1; the refrigerator 100 also includes a door 12, which is rotatably connected to the cabinet 11 and is configured to open or close the first opening 112, so that when it is necessary to take out the items in the storage compartment 111, the door 12 can be opened and the items in the storage compartment 111 can be taken out from the first opening 112; normally the door 12 is closed to prevent the cold air in the storage compartment 111 from leaking out, thereby maintaining the temperature inside the storage compartment 111.

[0089] In some embodiments, the refrigerator 100 further includes a cooling device (not shown) disposed inside the cabinet 11 and used to cool the storage compartment 111.

[0090] Optionally, the cooling device may use a cooling cycle for compressing, condensing, and evaporating the refrigerant to generate cold air and supply it to the storage compartment 111. This cooling device may include a compressor for compressing the refrigerant, a condenser for condensing the compressed refrigerant, an expansion valve for expanding the condensed refrigerant, and an evaporator for evaporating the expanded refrigerant to remove heat. The compressor, condenser, expansion valve, and evaporator constitute a cold cycle in which cooling air is supplied to the storage compartment 111. As a common component, a fan may be installed adjacent to the evaporator to force air circulation, blowing the cold air generated at the evaporator into the storage compartment 111. The temperature of the storage compartment 111 can be controlled by adjusting the fan's airflow and direction, adjusting the amount of circulating refrigerant, or adjusting the compressor's compression frequency to control the refrigeration load.

[0091] In some embodiments, such as Figures 3 to 5 As shown, in order to enable the door 12 to rotate relative to the cabinet 11 to open the first opening 112, the refrigerator 100 also includes an upper cover 13 and a hinge assembly 14. The upper cover 13 is located at the top of the door 12 in the height direction f3 of the cabinet 11, and the upper cover 13 has a shaft hole 131 that passes through the height direction f3 of the cabinet 11 on the side in the width direction f2 of the cabinet 11. The hinge assembly 14 has a pivot 141, which is rotatably inserted in the pivot hole 131. Thus, when the user acts on one side of the door 12, the pivot hole 131 will rotate relative to the pivot 141 to open the door 12.

[0092] In some embodiments, to achieve the left and right interchangeable door opening design of the refrigerator 100, the upper end cover 13 is provided with shaft holes 131 on both sides of the body 11 in the width direction f2, respectively, which pass through the body 11 in the height direction f3; the hinge assembly 14 is in two sets, and the two sets of hinge assemblies 14 are respectively detachably disposed on the top of the body 11 in its height direction f3, and each set of hinge assembly 14 is provided with a pivot 141, which is detachably rotatably inserted into the shaft hole 131; thus, when the user needs to open the door on the left, such as Figure 1 As shown, a hinge assembly 14 is installed on the right side of the housing 11. The pivot 141 of the hinge assembly 14 is rotatably inserted into the shaft hole 131 on the right side, while no hinge assembly 14 is installed on the left side. Therefore, the user can open the door 12 by acting on the left side. Similarly, when the user needs to open the door from the right side, such as... Figure 6 As shown, a hinge assembly 14 is installed on the left side of the cabinet 11. The pivot 141 of the hinge assembly 14 is rotatably inserted into the shaft hole 131 on the left side, while no hinge assembly 14 is installed on the right side. Thus, the user can open the door 12 by acting on the right side of the door body 12; thereby providing the refrigerator 100 with two interchangeable assembly modes of opening the left and right doors.

[0093] Optionally, the hinge assembly 14 can be connected to the housing 11 by at least one of the following connection methods: threaded connection, snap-fit ​​connection, and magnetic connection.

[0094] In some embodiments, the door 12 is provided with electronic components that are connected to the main control board inside the cabinet 11. Thus, the refrigerator 100 can be controlled and adjusted in various ways through the electronic components, such as adjusting the temperature and humidity inside the storage compartment 111.

[0095] In some embodiments, the electronic components may include a display screen 121, which can be used to display or input information to perform various controls and adjustments on the refrigerator 100.

[0096] In some embodiments, the electronic components may include a voice interaction module, whereby a user can issue voice commands to the door 12 to control and manage the refrigerator 100.

[0097] In some embodiments, such as Figure 6 and Figure 7As shown, to facilitate the electrical connection between the door 12 and the cabinet 11, the cabinet 11 has a wire outlet hole 113 at its top in the height direction f3. The hinge assembly 14 has a wire passage space 143 communicating with the wire outlet hole 113, and the pivot 141 has a wire passage hole 142 extending along the height direction f3 of the cabinet 11. This wire passage hole 142 communicates with both the pivot hole 131 and the wire passage space 143. The refrigerator 100 also includes a connecting wire assembly 15, which includes a first... The first connecting wire 151 is disposed inside the housing 11, and one end of the first connecting wire 151 passes through the wire outlet hole 113 and is located in the wire passage space 143; the second connecting wire 152 is disposed inside the door 12, and one end of the second connecting wire 152 passes through the wire passage hole 142 and the shaft hole 131, and exits from the wire passage hole 142 and is located in the wire passage space 143 to connect with the first connecting wire 151, thereby realizing the electrical connection between the door 12 and the housing 11.

[0098] In some embodiments, in order to simultaneously maintain the electrical connection between the door 12 and the housing 11, and to achieve a design that allows for interchangeable left and right door opening, there are two cable outlet holes 113, which are located on both sides of the housing 11 in its width direction f2; two sets of hinge assemblies 14 are detachably disposed on the top of the housing 11 in its height direction f3, and respectively cover the two cable outlet holes 113; there are two sets of connecting wire assemblies 15, one end of the first connecting wire 151 of each connecting wire assembly 15 is connected to a first connector 153, the first connector 153 passes through the cable outlet hole 113 and is located in the wire passage space 143, and one end of the second connecting wire 152 of each connecting wire assembly 15 is connected to a second connector 154, the second connector 154 is located in the wire passage space 143 and is detachably connected to the first connector 153.

[0099] Therefore, when the user needs the door to open from the left, the hinge assembly 14 is installed on the right side, and the first connecting wire 151 and the second connecting wire 152 of the right-side connecting wire assembly 15 are connected and conductive through the first connector 153 and the second connector 154. Conversely, when the user needs the door to open from the right, the hinge assembly 14 is installed on the left side, and the first connector 153 and the second connector 154 of the left-side connecting wire assembly 15 are separated, i.e., the first connecting wire 151 and the second connecting wire 152 of the left-side connecting wire assembly 15 are separated. The first connecting line 151 and the second connecting line 152 are connected and conductive through the first connector 153 and the second connector 154. However, the hinge assembly 14 is not installed on the right side. The first connector 153 and the second connector 154 of the right connecting line assembly 15 are separated, that is, the first connecting line 151 and the second connecting line 152 of the right connecting line assembly 15 are separated. This provides the refrigerator 100 with two interchangeable assembly modes for left and right doors, which can achieve the design of interchangeable left and right doors of the refrigerator 100 while ensuring that the cabinet 11 and the door 12 maintain electrical connection.

[0100] In some embodiments, such as Figure 8 , Figure 9 and Figure 10 As shown, the second connector 154 is square in shape, such as a rectangle or a square, and the length of the second connector 154 is greater than the diameter of the shaft hole 131. The upper end cover 13 is also provided with square through holes 132 on both sides of the housing 11 in the width direction f2 and in the height direction f3 of the housing 11. The square through holes 132 and the shaft hole 131 are arranged in the width direction f2 of the housing 11, and a communication port 133 is provided between the square through holes 132 and the shaft hole 131. The wall of the wire hole 142 is provided with a notch 144. The second connector 154 can pass through the square through hole 132 outside the door 12, the second connecting wire 152 can enter the shaft hole 131 from the square through hole 132 through the communication port 133, and the second connecting wire 152 can enter the wire hole 142 from the notch 144.

[0101] That is, the second connector 154 can pass through the square through hole 132 outside the door body 12, and after the second connector 154 passes through, the second connecting line 152 moves through the connecting port 133 into the shaft hole 131, so that the second connecting line 152 returns to the shaft hole 131. The second connecting line 152 can also enter the wire hole 142 through the notch 144 to enter the wire space 143 of the hinge assembly 14 and connect with the first connector 153, thereby realizing the electrical connection between the door body 12 and the housing 11. This avoids the need to open a large shaft hole 131 in the upper end cover 13 for the second connector 154 to pass through. Thus, without increasing the thickness of the door body 12, the second connecting line 152 can be inserted into the shaft hole 131 and the wire hole 142, and the second connector 154 can be located in the door body 12 and connected with the first connector 153 to realize the electrical connection between the door body 12 and the housing 11.

[0102] In some embodiments, each hinge assembly 14 includes a first hinge member 14a and a second hinge member 14b. The first hinge member 14a is detachably disposed on the top of the housing 11 in its height direction f3, and a pivot 141 is disposed on the first hinge member 14a. The second hinge member 14b is separately disposed from the first hinge member 14a and detachably connected to the top of the housing 11. The second hinge member 14b covers the first hinge member 14a, the wire passage hole 142 and the wire outlet hole 113, and a wire passage space 143 is formed between the second hinge member 14b and the first hinge member 14a.

[0103] With this configuration, during assembly, the first hinge component 14a can be fixed to the housing 11 first, allowing the first connecting wire 151 to pass through the shaft hole 131 and the wire passage hole 142. The first connector 153 and the second connector 154 are positioned above the first hinge component 14a for insertion. Then, the second hinge component 14b is fixedly connected to the housing 11, covering the first hinge component 14a, the wire passage hole 142, and the wire outlet hole 113, placing the first connector 153 and the second connector 154 within the wire passage space 143. This makes the insertion of the first connector 153 and the second connector 154 visible, facilitating their insertion. During disassembly, the second hinge component 14b can be removed first, exposing the first connector 153 and the second connector 154, thus facilitating their separation.

[0104] In some embodiments, the upper cover 13 is provided with first receiving grooves 134 on both sides of the box body 11 in the width direction f2. The openings of the first receiving grooves 134 are all facing upwards. A square through hole 132 is formed on the bottom wall of the first receiving groove 134. The first receiving grooves 134 are used to receive the second connector 154 and the second connecting line 152. The refrigerator 100 also includes two first covers 16, which are detachably covered by the two first receiving grooves 134.

[0105] With this configuration, when the user needs to open the door from the left, the second connecting wire 152 and the second connector 154 on the left are stored in the first receiving slot 134 on the left, and a first cover 16 is installed in the first receiving slot 134 on the left to prevent the second connecting wire 152, the second connector 154, and the square through hole 132 on the left from being exposed. The hinge assembly 14 is installed in the first receiving slot 134 on the right, and a first cover 16 is installed in the first receiving slot 134 on the right to prevent the square through hole 132 on the right from being exposed. Similarly, when the user needs to open the door from the right, the hinge assembly 14 is installed in the second mounting slot on the left, and a first cover 16 is installed in the first receiving slot 134 on the left to prevent the square through hole 132 on the left from being exposed. The second connecting wire 152 and the second connector on the right are stored in the first receiving slot 134 on the left. The second connecting wire 154 is stored in the first receiving slot 134 on the right side, and a first cover 16 is installed on the first receiving slot 134 on the right side to prevent the second connecting wire 152, the second connector 154 and the square through hole 132 on the right side from being exposed. That is, this application can install a hinge assembly 14 on one side to cover the shaft hole, and at the same time, the first cover 16 is used to cover the square through hole 132 on the same side. On the other side, the first receiving slot 134 is also covered by the first cover 16 to cover the square through hole 132. This can prevent the second connecting wire 152 and the second connector 154 from being exposed, prevent dust, protect the second connecting wire 152 and the second connector 154, and also help improve the product appearance integrity and aesthetics of the refrigerator 100.

[0106] In some embodiments, such as Figure 11 and Figure 12 As shown, the cabinet 11 has two second receiving slots 114 on its top in the height direction f3. The opening of each second receiving slot 114 is facing upward, and the two second receiving slots 114 are respectively located on both sides of the cabinet 11 in the width direction f2. The cable outlet hole 113 is formed on the bottom wall of the second receiving slot 114. The second receiving slot 114 is used to receive the first connector 153 and the first connecting wire 151. The refrigerator 100 also includes two second covers 17, which are detachably covered by the two second receiving slots 114.

[0107] With this configuration, utilizing two hinge assemblies 14 and two second covers 17, when the user needs to open the door from the left, the first connecting wire 151 and the first connector 153 on the left are stored in the second receiving slot 114 on the left, and the second cover 17 is installed in the second receiving slot 114 on the left to prevent the first connecting wire 151, the first connector 153, and the cable outlet 113 on the left from being exposed. The hinge assembly 14 is installed on the right side of the housing, and the pivot of the hinge assembly passes through the shaft hole on the right side. Similarly, when the user needs to open the door from the right, the hinge assembly 14 is installed in the first mounting slot on the left, and the first connecting wire 151 and the first connector 153 on the right are stored in the second receiving slot 114 on the left. The second receiving slot 114 on the right side is fitted with a second cover 17 to prevent the first connecting wire 151, the first connector 153, and the outlet hole 113 on the right side from being exposed. That is, this application can install the hinge assembly 14 on one side while using the second cover 17 to cover and seal the second receiving slot 114 on the other side to cover and seal the outlet hole 113. This not only achieves waterproofing and dustproofing, ensuring the quality and performance of the refrigerator 100, but also prevents the first connecting wire 151 and the first connector 153 from being exposed, thereby improving the product appearance integrity and aesthetics of the refrigerator 100.

[0108] Understandably, since the refrigerator 100 is shipped with the door opening to the left, the hinge assembly 14 is installed on its right side. The pivot 141 of the hinge assembly 14 is rotatably inserted into the right side pivot hole 131 of the door body 12. The right side first connecting wire 151 and the first connector 153 pass through the right side cable outlet hole 113 and are located in the cable passage space 143. The right side second connecting wire 152 passes through the right side pivot hole 131 and cable passage hole 142, and the right side second connector 154 is located in the cable passage space 143 and is connected to the first connecting wire 151. Connector 153 is connected, the left first connecting wire 151 passes through the outlet hole 113, and the left first connecting wire 151 and the first connector 153 are stored in the left second receiving slot 114. The left second connecting wire 152 passes through the square through hole 132, and the left second connecting wire 152 and the second connector 154 are stored in the first receiving slot 134. At the same time, the right second receiving slot 114 and the right first receiving slot 134 are covered by the second cover 17 to maintain the integrity of the appearance of the refrigerator 100.

[0109] If the refrigerator 100 is shipped with a right-opening door, then the refrigerator 100 has a hinge assembly 14 installed on its left side. The pivot 141 of the hinge assembly 14 is rotatably inserted into the left-side pivot hole 131 of the door body 12. The left-side first connecting wire 151 and the first connector 153 exit from the left-side wire outlet hole 113 and are located in the wire passage space 143. The left-side second connecting wire 152 passes through the left-side pivot hole 131 and the wire passage hole 142, and the left-side second connector 154 is located in the wire passage space 143 and is connected to the first connector 153. 53 connection, the right first connecting wire 151 passes through the outlet hole 113, and the right first connecting wire 151 and the first connector 153 are stored in the right second receiving slot 114. The right second connecting wire 152 passes through the square through hole 132, and the right second connecting wire 152 and the second connector 154 are stored in the first receiving slot 134. At the same time, the left second receiving slot 114 and the left first receiving slot 134 are covered by the second cover 17 to maintain the integrity of the appearance of the refrigerator 100.

[0110] When the user needs to switch from left-opening to right-opening mode, the right hinge assembly 14 is disassembled, and the right first connector 153 and the second connector 154 are disconnected. The left second cover 17 and the second cover 17 are also disassembled. At the same time, the hinge assembly 14 is installed on the left side, and the left first connector 153 and the second connector 154 are connected. The right second cover 17 and the second cover 17 are then installed. The replacement operation is simple and quick.

[0111] As mentioned above, in order to ensure that the second connector 154 can pass smoothly out of the door 12 and be located outside the door 12 while taking into account the miniaturization design of the door body 12, a square through hole 132 matching the shape of the second connector 154 is provided on the upper end cover 13. The square through hole 132 and the shaft hole 131 are arranged along the width direction f2 of the housing 11, and the peripheral sidewalls of the square through hole 132 and the shaft hole 131 are connected to form a communication port 133. Thus, the second connector 154 can first pass through the square through hole 132 and be located outside the door body 12, and then the second connecting line 152 enters the shaft hole 131 through the communication port 133 and is positioned inside the shaft hole 131.

[0112] However, when using sealing tape to wrap the square bosses corresponding to the square through-holes 132 and shaft holes 131 to seal them, the sealing tape does not adhere well to the four opposite corners of the square bosses, easily forming dead corners and resulting in poor sealing. This can lead to leakage problems during the subsequent foaming process, with foam material often overflowing. This is especially true for refrigerators 100 that can open with interchangeable left and right doors. Since there are square through-holes 132 and shaft holes 131 on both sides of the door 12, the sealing effect of the door 12 is even worse, making it more prone to leakage problems during the subsequent foaming process. This results in poorer finished quality of the door 12 and affects its use.

[0113] In some embodiments, such as Figure 13 and Figure 14 As shown, the upper end cover 13 has two elliptical protrusions 135 on each side of the box width direction f2. Both elliptical protrusions 135 are located inside the door body 12, and each elliptical protrusion 135 is respectively arranged around the shaft hole 131 and the square through hole 132. Each elliptical protrusion 135 is used for sealing tape to wrap and stick, so as to seal the shaft hole 131 and the square through hole 132. This can effectively prevent the foam material inside the door body 12 from leaking out from the shaft hole 131 and the square through hole 132, thereby preventing the leakage of foam material inside the door body 12 and effectively reducing the occurrence of foam leakage in the door body 12, ensuring the yield of the door body 12.

[0114] Because the outer periphery of the elliptical boss 135 is relatively smooth and rounded, it is convenient to apply sealing tape (such as masking tape), avoiding the existence of sealing dead corners that would affect the sealing performance of the sealing tape on the square through hole 132 and the shaft hole 131. This can more effectively prevent the foam material inside the door from leaking out through the shaft hole 131 and the square through hole 132, thus preventing the leakage of foam material inside the door and further reducing the occurrence of door leakage, thereby ensuring the yield rate of the door. Moreover, the elliptical boss 135 occupies less space than the circular boss, especially in the depth direction of the box, so it can be used for the upper cover with a relatively small thickness in the depth direction of the box, which is conducive to meeting the requirements of the thin and light design of the door.

[0115] In some embodiments, such as Figure 15 and Figure 16As shown, a square boss 115 is provided inside the housing 11. The square boss 115 is arranged around the periphery of the outlet hole 113, and the diagonal corners of the square boss 115 are rounded. The square boss 115 is used for sealing tape to wrap and stick, so as to seal the outlet hole 113. This can effectively prevent the foam material inside the housing 11 from leaking out of the outlet hole 113, thereby preventing the leakage of foam material inside the housing 11 and effectively reducing the occurrence of foam leakage in the housing 11, ensuring the yield rate of the housing 11.

[0116] Because the square boss 115 has rounded corners at its opposite corners, the outer periphery of the square boss 115 is relatively smooth and easy to apply sealing tape (such as masking tape), avoiding dead corners that could affect the sealing performance of the sealing tape to the outlet hole 113. This can more effectively prevent the foam material inside the box 11 from leaking out of the outlet hole 113, thus preventing leakage of the foam material inside the box 11 and further reducing the occurrence of foam leakage in the box 11, thereby ensuring the yield rate of the box 11.

[0117] In some embodiments, the box 11 includes a main body 11a and two receiving boxes 11b. A storage chamber 111 and a first opening 112 are both formed in the main body 11a. The main body 11a has two second openings 116 at its top in the height direction f3, each communicating with the interior of the main body 11a. The two second openings 116 are located on opposite sides of the main body 11a in the width direction f2. Both receiving boxes 11b are disposed inside the main body 11a. Two second receiving slots 114 are respectively formed on two receiving boxes 11b, and the openings of the two second receiving slots 114 are respectively connected to two second openings 116. Two second covers 17 are respectively detachably covered on the two second openings 116. That is, a second receiving slot 114 is formed on a receiving box 11b, the opening of a second receiving slot 114 is connected to a second opening 116, and a second cover 17 is detachably covered on a second opening 116, thereby achieving the covering of the second receiving slot 114.

[0118] This design is equivalent to locally thickening the cabinet 11, forming a second receiving groove 114 at the thickened area to accommodate the first connecting wire 151 and the first connector 153. Compared to making the entire cabinet 11 thicker, forming the second receiving groove 114 directly on the cabinet 11 can reduce the weight of the cabinet 11 and the refrigerator 100. In other words, the design structure described above can accommodate the first connecting wire 151 and the first connector 153, thereby improving the product appearance integrity and aesthetics of the refrigerator 100 while making the refrigerator 100 lighter, thus meeting the requirements of lightweight design.

[0119] In some embodiments, the housing 11 further includes two sealing rings 18, which abut against the inner wall surfaces of the two receiving boxes 11b and the housing body 11a respectively. That is, one sealing ring 18 abuts against one receiving box 11b and the housing body 11a. Thus, the sealing ring 18 can be used to seal the connection between the receiving box 11b and the housing body 11a to prevent the foaming material inside the housing 11 from leaking out through the second opening 116 from the connection between the receiving box 11b and the housing body 11a. This can effectively reduce the occurrence of foam leakage in the housing 11 and ensure the yield rate of the housing 11.

[0120] Alternatively, the sealing ring 18 can be a rubber ring, silicone ring, plastic ring, or foam ring, etc.

[0121] For example, such as Figure 16 and Figure 17 As shown, a flange 11b1 is provided on the outer peripheral side of the receiving box 11b along the radial direction of the cable outlet hole 113. The flange 11b1 is arranged around the periphery of the opening of the second receiving groove 114, and an annular protrusion 11b2 is provided on the flange 11b1 in the direction toward the second opening 116. The annular protrusion 11b2 is arranged around the periphery of the opening of the second receiving groove 114 and abuts against the inner wall surface of the box body 11. The annular protrusion 11b2 is inclined relative to the flange 11b1, and the inner diameter of the annular protrusion 11b2 gradually increases in the direction toward the second opening 116, that is, in the upward direction. The annular protrusion 11b2 and the flange 11b1 enclose and form an accommodating space. The sealing ring 18 is disposed in the accommodating space and abuts against the inner wall surface of the box body 11a to seal the connection between the annular protrusion 11b2 and the inner wall surface of the box body 11a.

[0122] This not only allows the sealing ring 18 to seal the connection between the annular protrusion 11b2 and the box body 11a, preventing the foam material inside the box body 11 from leaking out through the second opening 116 from the connection between the annular protrusion 11b2 and the box body 11a, but also, because the annular protrusion 11b2 is inclined relative to the flange 11b1 and its inner diameter gradually increases in the direction toward the second opening 116 (i.e., upward), the foam material overflowing from the connection between the annular protrusion 11b2 and the box body 11a will preferentially enter the accommodating space under the guiding action of the annular protrusion 11b2, thereby reducing the probability of the foam material overflowing from the second opening 116.

[0123] In some embodiments, combined with Figures 16 to 18As shown, the second receiving slot 114 has a first hook 117 protruding from its slot wall. The first hook 117 extends axially along the cable outlet hole 113 and passes through the second opening 116 outside the box body 11a, and abuts against the outer top surface of the box body 11a to fix the receiving box 11b to the box body 11a.

[0124] This design allows the containment box 11b to be fixed to the main body 11a by snap-fit, making the connection method relatively simple and facilitating the assembly between the containment box 11b and the main body 11a.

[0125] In some embodiments, such as Figure 18 and Figure 19 As shown, one of the groove walls of the second receiving groove 114 and the second cover 17 is provided with a slot 118, and the other of the groove walls of the second receiving groove 114 and the second cover 17 is provided with a second hook 171. That is, when the groove wall of the second receiving groove 114 is provided with a slot 118, the second cover 17 is provided with a second hook 171, and when the groove wall of the second receiving groove 114 is provided with a second hook 171, the second cover 17 is provided with a slot 118. The second hook 171 engages with the slot 118 to fix the second cover 17 to the box body 11a.

[0126] With this configuration, the storage box 11b can provide a snap-fit ​​point for the second cover 17, so that the second cover 17 can be fixed to the box body 11a by snap-fit. The connection method is relatively simple and facilitates the assembly between the second cover 17 and the box body 11a.

[0127] For example, when the slot 118 is formed on the wall of the second receiving groove 114 and the second hook 171 is formed on the second cover 17, the slot 118 can be specifically formed in the part of the first hook 117 located in the second receiving groove 114. This can form a relatively deep slot 118, thereby increasing the engagement amount of the slot 118 and the second hook 171, and thus improving the connection stability of the second hook 171 and the slot 118.

[0128] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0129] Furthermore, the embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the content of this specification should not be construed as a limitation of this application, and the protection scope of this application should be determined by the appended claims.
