Technical Field

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

[0002] Refrigerators are an indispensable household appliance. As people's living standards improve, their requirements for refrigerators are also increasing, especially regarding the space they occupy and their capacity.

[0003] In related technologies, the refrigerator door and cabinet are rotatably connected by a hinge assembly. The hinge assembly protrudes from the top surface of the cabinet, and the top surface of the door protrudes from the top surface of the cabinet, thus concealing the protruding hinge assembly.

[0004] However, the top surface of the door protrudes beyond the top surface of the refrigerator body, which increases the overall size of the refrigerator and the portion of the door that protrudes above the body is not utilized, affecting the effective volume of the refrigerator. Utility Model Content

[0005] This application provides a refrigerator that helps to increase the effective volume of the refrigerator.

[0006] In a first aspect, embodiments of this application provide a refrigerator, which includes:

[0007] The box is constructed to form a storage compartment; a main control board is installed on the box.

[0008] The door is rotatably connected to the cabinet via a hinge mechanism to open or close the storage compartment; the door is equipped with electrical components, which are electrically connected to the main control board via cables.

[0009] The hinge mechanism includes:

[0010] A hinge plate is fixed to the top surface of the housing;

[0011] A hinge shaft is disposed on the hinge plate and is rotatably connected to the door body;

[0012] A cover plate assembly is fixed to the top side of the housing; a wiring interval is formed below the cover plate assembly; the top surface of the cover plate assembly does not protrude from the top surface of the door.

[0013] At least a portion of the hinge plate is lower than the top surface of the housing and is provided with the hinge shaft; the portion of the hinge plate lower than the top surface of the housing and the cover plate assembly are spaced apart along the height direction of the housing, the space forming a wiring interval; a portion of the cable is arranged in the wiring interval.

[0014] In this refrigerator embodiment, the door is rotatably connected to the cabinet via a hinge mechanism. The hinge mechanism includes a hinge plate, a hinge shaft, and a cover plate assembly. The hinge plate is fixed to the top surface of the cabinet, and the hinge shaft is disposed on the hinge plate and rotatably connected to the door, allowing the door to rotate relative to the cabinet. A wiring interval is provided below the cover plate assembly for wiring. At least a portion of the hinge plate is positioned below the top surface of the cabinet, thus forming a large gap above the portion of the hinge plate below the top surface of the cabinet. A gap exists between the portion of the hinge plate below the top surface of the cabinet and the cover plate assembly along the height direction of the cabinet, forming a wiring interval that provides space for cable routing. The cables are partially routed within the wiring interval. Thus, while maintaining the refrigerator's external dimensions, the effective volume of the refrigerator can be increased by increasing the height of the cabinet. By positioning at least a portion of the hinge plate below the top surface of the cabinet, sufficient space is reserved for cable routing.

[0015] In some embodiments of this application, a mounting portion is formed on the top surface of the housing, and the mounting surface of the mounting portion is lower than the top surface of the housing; the mounting portion extends to the front of the housing;

[0016] The hinge plate is fixed to the mounting surface such that the hinge plate is lower than the top surface of the housing and forms a first gap with the cover plate assembly above it;

[0017] The wiring interval includes the first interval.

[0018] In this embodiment, by setting a mounting surface lower than the top surface of the housing and fixing the hinge plate to the mounting surface, the hinge plate is lower than the top surface of the housing, and the top surface of the hinge plate is connected to the cover plate above it. There are large gaps between them to form the first interval, providing space for cable routing. Furthermore, it allows for the possibility of increasing the effective volume of the refrigerator by increasing the height of the enclosure.

[0019] In some embodiments of this application, the box body includes a box shell and a box liner, the box liner is installed inside the box shell, and the box liner is configured to form the storage compartment; the top surface of the box shell is provided with an installation notch;

[0026] The second limiting edge is connected to the bottom side of the first limiting edge; the second limiting edge is located on the front side of the box body; the second limiting edge abuts against the inner surface of the front wall of the box shell.

[0027] In this embodiment, the mounting box forms a mounting surface by setting the box body, and the first limiting edge abuts against the top wall of the cabinet, while the second limiting edge abuts against the front wall of the cabinet. This helps improve the sealing between the mounting box and the cabinet. Furthermore, when a heat insulation layer is formed by foaming between the cabinet and the liner, the heat insulation layer pushes the first and second limiting edges outward, making the fit between the two limiting edges and the cabinet more tight. Moreover, the first and second limiting edges are located inside the cabinet and not exposed, which helps improve the appearance of the top of the refrigerator.

[0028] In some embodiments of this application, the hinge plate includes:

[0029] The first plate is fixed to the top surface of the box body;

[0030] The second plate is connected to the first plate and is provided with the hinge shaft; the second plate is lower than the top surface of the housing.

[0031] The cable portion is positioned above the second plate portion.

[0032] In this embodiment, the second plate of the hinge plate protrudes forward from the housing and is lower than the top surface of the housing, and is provided with a hinge shaft, so that part of the hinge plate is lower than the top surface of the housing. There is a large gap space above the second plate, so that the cables of electrical components on the door can be arranged above the second plate, providing sufficient wiring space.

[0033] In some embodiments of this application, the hinge plate further includes a connecting plate portion, which connects the first plate portion and the second plate portion; the connecting plate portion abuts against the front of the housing.

[0034] The hinge plate in this embodiment of the application is provided with a connecting plate portion, such that the second plate portion is lower than the top surface of the box body, and the connecting plate portion abuts against the front of the box body, which helps to improve the positioning of the hinge plate during installation and improves the convenience of hinge plate installation.

[0036] The cable extends from above the second plate portion to the second interval;

[0037] The wiring interval includes the second interval.

[0038] In this embodiment, by providing a second-spaced cable arrangement on the side of the first plate, the cables can be arranged on the side of the hinge plate, providing ample wiring space. This makes it possible to increase the effective volume of the refrigerator by increasing the height of the cabinet.

[0039] In some embodiments of this application, the cover assembly includes a lid, a portion of which is located on the top side of the housing; another portion of the lid extends forward, protruding from the front of the housing and abutting against the front of the housing; an opening is provided on the front side of the lid to expose a portion of the hinge plate and to provide the hinge shaft.

[0040] The front side of the lid protrudes from the front of the box body and abuts against the front of the box body, providing positioning for the lid installation and helping to improve the reliability and convenience of lid installation.

[0041] In some embodiments of this application, the cover assembly further includes a hinged cover, which is fixed to the portion of the hinge plate that protrudes forward from the front of the housing and forms a third gap with the hinge plate so that the cable enters the underside of the cover via the third gap;

[0042] The wiring interval includes the third interval.

[0043] In this embodiment, a hinge cover is provided on the portion of the hinge plate protruding from the front side of the housing, forming a third gap. This allows the cables of electrical components on the door to extend through the third gap to the bottom of the cover. Since the hinge plate is lower than the top surface of the housing, there is ample space above the entire hinge plate, providing sufficient room for wiring.

[0044] Secondly, embodiments of this application provide a refrigerator, which includes:

[0045] The box is constructed to form a storage compartment; a main control board is installed on the box.

[0046] The door is rotatably connected to the box via a hinge mechanism to open or close the storage compartment;

[0047] The hinge mechanism includes:

[0048] A hinge plate is fixed to the top surface of the housing;

[0075] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

[0076] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0077] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.

[0078] 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.

[0079] 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. Therefore, 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.

[0080] 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. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0081] The volume ratio of a refrigerator refers to the ratio between its internal effective volume and its external volume, usually expressed as a percentage. The effective volume of a refrigerator refers to the actual usable space inside the refrigerator for storing food, directly affecting how much food a user can store. People have increasingly higher demands for the volume ratio and effective volume of refrigerators. As people's living standards improve, their requirements for refrigerator products are also increasing, especially regarding the space occupied and effective volume.

[0082] In related technologies, the refrigerator door and cabinet are rotatably connected by a hinge assembly. The hinge assembly protrudes from the top surface of the cabinet, and the top surface of the door protrudes from the top surface of the cabinet, thus concealing the protruding hinge assembly.

[0083] However, the top surface of the door protrudes beyond the top surface of the refrigerator body, increasing the overall size of the refrigerator and leaving the portion of the door above the body unused, thus affecting the refrigerator's effective volume. For example, if the door protrudes approximately 25mm above the body, this space is considered unusable volume.

[0084] The researchers of this application considered increasing the height of the refrigerator body without increasing the overall height of the refrigerator, thereby increasing the effective volume of the refrigerator. However, increasing the height of the body results in insufficient wiring space within the hinge box and also affects the installation of the door control switch.

[0085] Therefore, the refrigerator provided in this application embodiment has at least a portion of its hinge plate lower than the top surface of the cabinet, so that the top of at least a portion of the hinge plate forms a wiring space. In this way, while increasing the effective volume of the refrigerator, sufficient space is provided for cable arrangement.

[0086] 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.

[0087] Reference Figure 1 Some embodiments of this application provide a refrigerator including a cabinet 100, which can be configured to have a storage compartment 121 for storing items. An access opening is formed on the front side of the storage compartment 121.

[0088] Multiple storage compartments 121 can be provided to expand storage space. Depending on the storage temperature of the storage compartments 121, they can include at least one refrigerated compartment and at least one frozen compartment. The internal temperature of the refrigerated compartment can be maintained between approximately 0°C and 5°C for storing items in refrigeration mode; the internal temperature of the frozen compartment can be maintained between approximately -30°C and 0°C for storing items in freezing mode.

[0089] In some possible implementations, at least one storage chamber 121 may also be configured as a vacuum chamber or a variable temperature chamber, etc., which will not be described in detail in the embodiments of this application.

[0090] For example, two storage compartments 121 can be provided, which can be stacked vertically or arranged side by side horizontally. One of them can be a refrigerator compartment and the other can be a freezer compartment.

[0091] In some embodiments, the refrigerator body 100 may include a liner 120 and a shell 110. The liner 120 may be configured to form a storage compartment 121 with a front opening, which serves as an access port. The shell 110 may be attached to the outside of the liner 120 to form the appearance of the refrigerator. The refrigerator body 100 may also include a heat insulation layer, which may be disposed between the liner 120 and the shell 110. The heat insulation layer can insulate the storage compartment 121 to minimize heat exchange between the storage compartment 121 and the outside of the refrigerator, thereby ensuring the refrigerator's cooling effect.

[0092] Combination Figure 3In some embodiments, the refrigerator shell 110 may include a top plate 111 and a bottom plate that are opposite to and spaced apart along the height direction Z of the refrigerator, with the top plate 111 located above the bottom plate. The refrigerator shell 110 may also include a first side plate 113 and a second side plate 114 that are opposite to and spaced apart along the width direction X of the refrigerator, with the first side plate 113 and the second side plate 114 respectively connected to the top plate 111 and the bottom plate on both sides along the width direction X of the refrigerator. The refrigerator shell 110 may also include a back plate, which is fixed to the rear side of the top plate 111, the bottom plate, the first side plate 113, the second side plate 114, and the second side plate 114. Thus, the top plate 111, the bottom plate, the first side plate 113, the second side plate 114, and the back plate enclose a mounting cavity with a front opening, allowing the refrigerator liner 120 to be installed within the mounting cavity. The back plate and the refrigerator door 200 are spaced apart and opposite to each other along the depth direction Y of the refrigerator body 100.

[0093] In some embodiments, the top plate 111, the first side plate 113, and the second side plate 114 are integrally formed as a single piece. For example, the two ends of a metal plate are bent to the same side to form a U-shaped structure, which can be called a U-shell. This arrangement helps to reduce the number of connection points of the housing 110, improves assembly efficiency, and also helps to improve the sealing performance of the housing 110.

[0094] The refrigerator may also include a main control box 400, which is mounted on the cabinet 100. For example, the main control box 400 is mounted on the top plate 111 of the cabinet 110; or, for another example, the main control box 400 is mounted on the back plate of the cabinet 110. The main control box 400 contains a main control board, which is used to control the operating status of the refrigerator.

[0095] Combination Figure 1 and Figure 2 The refrigerator in this embodiment may further include a door 200, which is rotatably connected to the cabinet 100 to open or close the access port. Exemplarily, the door 200 is hinged to the cabinet 100.

[0096] Each storage room 121 may be provided with one door 200; or, each storage room 121 may be provided with two doors 200, which may rotate in opposite directions to open or close the storage room 121.

[0097] In some embodiments of this application, the refrigerator may further include a hinge mechanism 300, and the door 200 is rotatably connected to the door body 200 through the hinge mechanism 300, so that the door body 200 can rotate relative to the cabinet 100.

[0098] In some embodiments, electrical components are provided on the door 200. These electrical components may include, but are not limited to, a display screen, touch panel, lights, speakers, door control switch 500, Wi-Fi module, sensors, etc. The electrical components on the door 200 are electrically connected to the main control board via cables, enabling signal transmission with the main control board and providing power to the electrical components on the door 200. The cables extend from the door 200 to the housing 100 via the hinge mechanism 300.

[0099] Of course, in some embodiments, electrical components may not be provided on the door 200.

[0100] In some embodiments, the refrigerator may further include a door control switch 500, which is mainly used to detect the open / closed state of the door 200. The door control switch 500 is configured to open when the door 200 opens the storage compartment 121 to control the start / stop of the refrigerator's lighting, fan, or cooling system.

[0101] The door control switch 500 can be a mechanical switch, which can be installed on the front side of the enclosure 100. When the door 200 is closed, the door 200 presses down the switch button to disconnect the circuit; when the door 200 is opened, the button pops out, and the door control switch 500 is turned on.

[0102] The door control switch 500 can be a magnetic switch, which includes a magnet and a reed switch. The magnet can be installed on the door 200, and the reed switch can be installed on the housing 100. When the door 200 is closed, the magnet causes the reed switch to open; when the door 200 is open, the magnet moves away from the reed switch, and the circuit is connected.

[0103] Of course, the gate switch 500 can also be a Hall effect sensor, a micro switch, etc.

[0104] The refrigerator in this embodiment may further include a refrigeration system for reducing the air temperature in the storage compartment 121. Exemplarily, the refrigeration system may be housed within the cabinet 100. The refrigeration system may include a compressor, condenser, expansion valve, and evaporator connected in a cycle.

[0105] During refrigeration system operation, the compressor compresses refrigerant vapor to generate high-temperature, high-pressure refrigerant vapor, which is then transported to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then transported to the expansion valve. The expansion valve reduces the pressure of the refrigerant liquid, transforming the high-pressure, low-temperature refrigerant liquid into a low-pressure, low-temperature refrigerant liquid, which is then transported to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside storage compartment 121.

[0106] In some embodiments, an evaporator may be provided, located at the rear of the freezer compartment, to provide cold air to both the freezer and refrigerator compartments.

[0107] In some other embodiments, an evaporator may be provided. The refrigerator may only have a refrigerator compartment, and the evaporator may be located at the rear of the refrigerator compartment.

[0108] In some other embodiments, there may be two evaporators: a refrigeration evaporator and a freezing evaporator. The refrigeration evaporator is located at the rear of the refrigeration compartment and is used to provide cold air to the refrigeration compartment. The freezing evaporator is located at the rear of the freezing compartment and is used to provide cold air to the freezing compartment.

[0109] Combination Figure 4 and Figure 5 In some embodiments of this application, the hinge mechanism 300 includes a hinge plate 310, which is fixed to the top surface of the housing 100. The fixing methods of the hinge plate 310 include, but are not limited to, snap-fit ​​and screw connection.

[0110] In some embodiments, the hinge plate 310 is fixed to the top side of the housing 100 by screws 360, which are fixed from top to bottom, making the installation of the hinge plate 310 simple.

[0111] The hinge plate 310 has a local upward protrusion forming a bulge, which can improve the structural strength of the hinge plate 310.

[0112] Combination Figure 5 The hinge plate 310 may include a plate body portion 311 and a protruding plate portion 312. The plate body portion 311 is fixed to the top of the housing 100, for example, by screws. The front end portion of the third plate portion extends forward and then bends towards the edge of the housing 100 to form the protruding plate portion 312. Along the depth direction of the housing 100, the protruding plate portion 312 protrudes from the front side of the housing 100.

[0113] The hinge mechanism 300 may further include a hinge shaft 320, which is disposed on the hinge plate 310, specifically on the protruding plate portion 312. The hinge shaft 320 is rotatably connected to the door body 200. A portion of the hinge plate 310 extends forward and protrudes from the front side of the housing 100, and is provided with the hinge shaft 320.

[0114] There can be two hinge shafts 320, that is, the hinge mechanism 300 is a dual-axis hinge, which can make the door 200 not occupy too much external space when it is opened.

[0115] There can be one hinge axis 320, that is, the hinge mechanism 300 is a single-axis hinge, which is simple in structure.

[0116] The hinge mechanism 300 may also include a cover plate assembly 301, which is fixed to the top side of the housing 100 and serves to cover and protect the hinge plate 310.

[0117] like Figure 4 As shown, the cover assembly 301 includes a cover 330, a portion of which is located on the top side of the housing 100, and the remaining portion of which may be located on the front side of the housing 100. The cover 330 covers the top of the hinge plate 310's body portion 311. The top surface of the cover 330 protrudes relative to the top surface of the housing 100. The cover 330 serves to cover and protect the hinge plate 310.

[0118] In some embodiments of this application, the door control switch 500 is fixed to the bottom of the cover 330. The door control switch 500 can be fixedly connected to the cover 330. For example, the door control switch 500 is snapped into the cover 330, and the connection method is simple.

[0119] This configuration allows the door switch 500 to be assembled into the cover 330 and then onto the top of the enclosure 100, simplifying the assembly of the door switch 500. Furthermore, it facilitates routing the door switch 500's cables below the cover 330, making wiring more convenient.

[0120] In some embodiments, the door switch 500 is located on one side of the hinge plate 310 along the width direction of the housing 100. This not only provides ample space for arrangement and avoids interference between the door switch 500 and the hinge plate 310, but also facilitates the wiring arrangement of the door switch 500.

[0121] The cover assembly 301 may further include a hinge cover 350, which is located on the front side of the housing 100 and covers the protruding portion 312 of the hinge plate 310. The hinge cover 350 can be snapped into the protruding portion 312, and the connection method and structure are simple.

[0122] In some embodiments, the top surface of the cover assembly 301 does not protrude beyond the top surface of the door 200. Exemplarily, the top surface of the cover assembly 301 is flush with the top surface of the door 200, which allows for a compact appearance of the refrigerator.

[0123] Of course, in some possible implementations, the top surface of the cover assembly 301 may be slightly lower than the top surface of the door 200.

[0124] A wiring interval 370 is formed below the cover plate assembly 301 so that the cables of the door control switch 500, the cables of electrical components on the door body 200, etc. are arranged within the wiring interval 370.

[0125] In some embodiments, at least a portion of the wiring interval 370 is located on the side of the hinge plate 310, which can make the interval between the cover 330 and the hinge plate 310 along the height direction of the cabinet 100 smaller, which helps to increase the height of the cabinet 100 and increase the effective volume of the refrigerator; it can also make the interval between the cover 330 and the top surface of the cabinet 100 larger, so as to form at least a portion of the wiring interval 370, providing sufficient space for the arrangement of cables.

[0126] In other embodiments, at least a portion of the wiring spacing 370 is located above the hinge plate 310, making the hinge mechanism 300 compact.

[0127] In some embodiments of this application, at least a portion of the hinge plate 310 is lower than the top surface of the cabinet 100, and a hinge shaft 320 is provided thereon. This can be understood as the hinge plate 310 being positioned below the top surface of the cabinet 100, with the hinge shaft 320 positioned on this portion. Thus, a large gap is formed above the portion of the hinge plate 310 below the top surface of the cabinet 100. The portion of the hinge plate 310 below the top surface of the cabinet 100 and the cover assembly 301 are spaced along the height direction of the cabinet 100, forming a portion of the wiring interval 370, providing space for cable arrangement. A portion of the cable is arranged within the wiring interval 370. Thus, while increasing the effective volume of the refrigerator, by setting at least a portion of the hinge plate 310 below the top surface of the cabinet 100, sufficient space is reserved for cable arrangement, making the hinge mechanism 300 and the cable arrangement structurally compact.

[0128] The top surface of the box 100 is the top surface of the top plate 111.

[0129] For example, in related technologies, a hinge plate is fixed to the top surface of the cabinet, and cables are arranged above the hinge plate, so that the door is approximately 25mm above the top surface of the cabinet. Using the solution of this application embodiment, at least a portion of the hinge plate is lower than the top surface of the cabinet to accommodate the cables. This allows for an increase of 15mm in the cabinet height, thereby increasing the effective volume of the refrigerator.

[0130] In some embodiments, the hinge plate 310 is lower than the top surface of the housing 100, so that a wiring interval 370 can be formed between the hinge plate 310 and the cover assembly 301, so that cables can be arranged above the hinge plate 310.

[0131] In other embodiments, a portion of the hinge plate 310 is lower than the top surface of the housing 100, and cables can be arranged above this portion; the gap above another portion of the hinge plate 310 is smaller, and cables can be arranged on the side of the hinge plate 310; a larger gap exists between the cover 330 on the side of the hinge plate 310 and the top surface of the housing 100 to arrange cables.

[0132] In some embodiments, electrical components are provided on the door 200. A portion of the cable of the electrical components is arranged above the hinge plate 310, which is below the top surface of the housing 100.

[0133] In some embodiments, no electrical components are provided on the door 200. The door control switch 500 is mounted on the front side of the enclosure 100, for example, at the top of the front side of the enclosure 100. The door control switch 500 is located on the side of the hinge plate 310. The electrical connection cable between the door control switch 500 and the main control board is arranged on the side of the hinge plate 310.

[0134] Combination Figure 5 and Figure 6 In some embodiments of this application, a mounting portion 130 is formed on the top surface of the housing 100, and the mounting surface 131 of the mounting portion 130 is lower than the top surface of the housing 100; the mounting portion 130 extends to the front of the housing 100.

[0135] For example, the top plate 111 of the housing 110 is recessed downward to form a mounting portion 130, which is an upward-opening recessed structure. The bottom surface of the mounting portion 130 forms a mounting surface 131. The front side of the mounting portion 130 extends to the front of the housing 100, such that a portion of the hinge plate 310 can extend to the outside of the mounting portion 130 to provide a hinge shaft 320.

[0136] For example, the top plate 111 of the housing 110 is provided with a notch so that the hinge plate 310 can be inserted into the housing 100 through the notch, so that the hinge plate 310 is lower than the top surface of the housing 100.

[0137] The hinge plate 310 is fixed to the mounting surface 131 so that the hinge plate 310 is lower than the top surface of the housing 100. There are several ways to fix the hinge plate 310 to the mounting surface 131; for example, the hinge plate 310 is snapped onto the mounting surface 131; another example is that the hinge plate 310 is fixed to the mounting surface 131 by screws 360. The cable portion is arranged above the hinge plate 310.

[0138] Reference Figure 7 and Figure 8 The hinge plate 310 and the cover assembly 301 above the hinge plate 310 form a first gap 371, and the wiring gap 370 includes the first gap 371. The hinge plate 310 and the cover 330 above it are spaced along the height direction of the housing 100 to form the first gap 371, so that a portion of the cable can be arranged above the hinge plate 310.

[0139] In this embodiment, by setting a mounting surface 131 that is lower than the top surface of the housing 100, and fixing the hinge plate 310 to the mounting surface 131, the hinge plate 310 is lower than the top surface of the housing 100, and the top surface of the hinge plate 310 is connected to the cover plate above it. There are large gaps between them to form the first gap 371, providing space for cable arrangement.

[0140] Refer again Figure 7 and Figure 8 In some embodiments of this application, the hinge cover 350 is fixed to the portion of the hinge plate 310 that protrudes forward from the front of the housing 100. Specifically, the hinge cover 350 is fixed above the protruding portion 312 of the hinge plate 310 and has a gap between it and the protruding portion 312 of the hinge plate 310 along the height direction of the housing 100, forming a third gap 373. The wiring gap 370 includes the third gap 373.

[0141] Thus, the cable enters the first interval 371 below the cover 330 via the third interval 373.

[0142] In this embodiment, a hinge cover 350 is provided on the portion of the hinge plate 310 protruding from the front side of the housing 100, forming a third interval 373. This allows the cables of electrical components on the door 200 to extend through the third interval 373 to the bottom of the cover 330. Since the hinge plate 310 is lower than the top surface of the housing 100, there is ample space above the entire hinge plate 310, providing sufficient space for wiring.

[0143] In some embodiments, combined with Figure 5 and Figure 6 The mounting portion 130 includes a base plate portion 132, the top surface of which forms a mounting surface 131. The mounting portion 130 may also include a limiting structure to limit the position of the hinge plate 310 within the mounting surface 131.

[0144] For example, the limiting structure includes two first limiting plates 133 that are opposite to each other and spaced apart along a first direction, and a portion of the hinge plate 310 is installed between the two first limiting plates 133 to limit the position of the hinge plate 310 along the first direction. The first direction may be the width direction of the housing 100.

[0145] For example, the limiting structure may further include a second limiting plate 134, which is located at the end of the hinge plate 310 opposite to the hinge axis 320, and there is a gap between the second limiting plate 134 and the bottom plate portion 132 along the height direction of the housing 100. The end of the hinge plate 310 opposite to the hinge axis 320 is inserted between the second limiting plate 134 and the bottom plate portion 132 to limit the position of the hinge plate 310 along the height direction of the housing 100.

[0146] In some embodiments, the mounting portion 130 may include a positioning portion 135, which is disposed on the mounting surface 131. The hinge plate 310 is provided with a mating portion 316, which engages with the positioning portion 135 to serve as a positioning and mounting feature for the hinge plate 310.

[0147] For example, the positioning part 135 can be a protruding structure provided on the mounting surface 131, and the mating part 316 can be a through hole provided on the hinge plate 310.

[0148] In some possible implementations, the top surface of the housing 110 is provided with a mounting notch 1111, which extends to the front side of the housing 110.

[0149] The hinge mechanism 300 also includes a mounting box 340, which is fitted into the housing 110 through a mounting notch 1111 to form a mounting portion 130.

[0150] The mounting box 340 is a box structure with an open top, and the inner surface of the bottom wall of the mounting box 340 forms a mounting surface 131. The front side of the mounting box 340 is also provided with an opening so that the front end of the hinge plate 310 can extend to the outside of the mounting box 340.

[0151] The mounting box 340 can be snapped onto the top plate 111 of the housing 110 via the mounting notch 1111. The mounting box 340 can also be glued to the top plate 111 of the housing 110, or connected with screws, etc.

[0152] A portion of the cover assembly 301 is fixedly connected to the mounting box 340 and covers the top of the mounting box 340. For example... Figure 6 As shown, the cover 330 is fixedly connected to the mounting box 340 and covers the top of the mounting box 340.

[0153] In this embodiment of the application, by providing an installation notch 1111 on the top surface of the housing 110 and inserting the installation box 340 through the installation notch 1111 to form the installation part 130, the processing of the housing 110 is simplified.

[0154] In some possible implementations, the door switch 500 can be installed inside the mounting box 340, and the door switch 500 can be located on the side of the protruding plate 312. This allows the door switch 500 to be installed inside the mounting box 340 first, and then assembled to the top plate 111 of the housing 110, improving assembly efficiency. In this way, the electrical connection cable between the door switch 500 and the main control board can be arranged above the protruding plate 312. The cables of the electrical components on the door 200 extend above the protruding plate 312, providing ample space for cable arrangement.

[0155] Reference Figure 5 and Figure 6The mounting box 340 can also form a sensor space 375, which can be located behind the door switch 500. The sensor space 375 can be used to arrange temperature and humidity sensors, etc.

[0156] The mounting box 340 may also form a wiring box section 374, which is located behind the hinge plate 310 and on one side of the sensor space 375 along the width direction of the housing 100. The wiring box section 374 is provided with a through hole so that the cable can enter the interior of the housing 110 through the through hole and connect to the main control board. The wiring interval 370 may also include the wiring box section 374.

[0157] like Figure 5 As shown, the cables for the electrical components on the door 200, and the electrical connection cables between the door control switch 500 and the main control board, can extend from above the hinge plate 310 to the junction box 374; the cables for the sensors in the sensor space 375 extend to the junction box 374. Among these, in Figure 5 In the diagram, the dashed line with an arrow indicates the general direction of the cable.

[0158] Reference Figure 6 In some implementations, the mounting box 340 includes: a box body 341, top and front openings of the box body 341, and the box body 341 forms a mounting surface 131.

[0159] For example, the box body 341 includes a bottom wall 3411 and a surrounding wall 3412 disposed on the bottom wall 3411. The surrounding wall 3412 has a front opening, and the surrounding wall 3412 and the bottom wall 3411 enclose the box body 341 with a top opening and a front opening. The bottom wall 3411 forms the bottom plate portion 132 of the mounting portion 130. A first limiting plate 133 may be disposed on the surrounding wall 3412.

[0160] The mounting box 340 may further include a first limiting edge 342, which is disposed on the outer side of the box body 341. The first limiting edge 342 is connected to the box enclosure wall 3412. (See reference...) Figure 8 and Figure 9 The first limiting edge 342 is located on the inner side of the housing 110. The first limiting edge 342 is arranged parallel to the top wall of the housing 110 and abuts against the top wall of the housing 110. The first limiting edge 342 contacts the top wall surface of the housing 110. The top plate 111 of the housing 110 forms the top wall of the housing 110.

[0161] Reference Figure 6 and Figure 8The mounting box 340 may further include a second limiting edge 343, which is connected to the bottom side of the first limiting edge 342; the second limiting edge 343 is located on the front side of the box body 341. The second limiting edge 343 may be parallel to the front wall of the box shell 110, and the second limiting edge 343 abuts against the inner surface of the front wall of the box shell 110. The second limiting edge 343 contacts the front wall surface of the box shell 110, and the second limiting edge 343 is located inside the box shell 110. The front side of the U-shaped shell bends and extends towards the access opening of the storage compartment 121 to form the front wall of the box shell 110.

[0162] In this embodiment, the mounting box 340 forms a mounting surface 131 by setting a box body 341. A first limiting edge 342 abuts against the top wall of the shell 110, and a second limiting edge 343 abuts against the front wall of the shell 110. This helps improve the sealing between the mounting box 340 and the shell 110. Furthermore, when a heat insulation layer is formed by foaming between the shell 110 and the liner 120, the heat insulation layer pushes the first limiting edge 342 and the second limiting edge 343 outwards, making the fit between the two limiting edges and the shell 110 even tighter. Moreover, the first limiting edge 342 and the second limiting edge 343 are located inside the shell 110 and are not exposed, which helps improve the appearance of the top of the refrigerator.

[0163] In some embodiments of this application, the cover 330 is snapped into the mounting box 340. The cover 330 is fixedly connected to the box body 341. Exemplarily, a buckle is provided on the box wall 3412 of the mounting box 340, and the cover 330 is constructed to form a snap-fit ​​opening. The fixed connection between the cover 330 and the mounting box 340 is achieved through the snap-fit ​​between the snap-fit ​​opening and the buckle.

[0164] In some embodiments, such as Figure 6 As shown, the box cover 330 may include a top plate 331 and a side plate 332. The side plate 332 is disposed on the bottom edge of the top plate 331. The top plate 331 is provided with a protruding structure, which is located inside the side plate 332 and forms a snap-fit.

[0165] The top plate 331 may also be provided with a fixing structure for fixing the door control switch 500. The fixing structure may include snap-fit ​​components and limit components, etc.

[0166] When the door switch 500 is a mechanical switch or a micro switch, an opening may be provided on the front side of the side panel 332 to expose the trigger part of the door switch 500 on the front side of the housing 100. An opening is provided on the front side of the cover 330 to expose a portion of the hinge plate 310 on the front side of the housing 100, and a hinge shaft 320 is provided thereon. This can be understood as the protruding portion 312 of the hinge plate 310 being exposed through the opening on the front side of the cover 330.

[0167] In some embodiments, combined Figure 4 and Figure 6 The lid 330 is located on the top side of the box body 100, and the other part of the lid 330 extends forward and protrudes from the front of the box body 100, with the lid 330 abutting against the front of the box body 100.

[0168] The side panel 332 includes a first part 3321 and a second part 3322. The first part 3321 is located above the top plate 111, and the bottom end of the first part 3321 abuts against the top plate 111. The second part 3322 is located in front of the first part 3321, and the second part 3322 extends downward to the front of the shell 110 and abuts against the front of the shell 110. In this way, the front of the side panel 332 abuts against the front of the shell 110, which helps to improve the reliability and convenience of installing the lid 330.

[0169] In some possible implementations of this application, combined with Figures 10 to 12 The hinge plate may include a first plate portion 313, which is fixed to the top surface of the housing 100. In some embodiments, the first plate portion 313 is fixed to the top plate 111, and the fixing method includes screw fixing, snap-fit ​​fixing, etc.

[0170] The hinge plate 310 may further include a second plate portion 314, which is connected to the first plate portion 313 and is provided with a hinge shaft 320. The second plate portion 314 is lower than the top surface of the housing 100, and the first plate portion 313 is fixed to the top surface of the housing 100. Therefore, the second plate portion 314 is lower than the first plate portion 313. The spacing above the second plate portion 314 is larger than the spacing above the first plate portion 313, allowing the cable portion to be arranged above the second plate portion 314.

[0171] In this embodiment, the second plate portion 314 of the hinge plate 310 protrudes forward from the housing 100, and the second plate portion 314 is lower than the top surface of the housing 100, and is provided with a hinge shaft 320, so that a portion of the hinge plate 310 is lower than the top surface of the housing 100. There is a large gap above the second plate portion 314, allowing the cables of electrical components on the door 200 to be arranged above the second plate portion 314, thus providing ample wiring space.

[0172] The first plate portion 313 forms the plate body portion of the hinge plate 310. The protruding plate portion of the hinge plate 310 includes the second plate portion 314.

[0173] like Figure 11 As shown, the front side of the lid 330 extends forward so that a portion of the lid 330 protrudes from the front side of the case 110. The portion of the lid 330 located on the top side of the case 110 can be directly fixed to the case 110.

[0174] The top plate 331 of the lid 330 extends forward and protrudes from the front side of the casing 110. Combined with... Figure 13 The box lid 330 may also include a box bottom plate 333, which is lower than the top surface of the box body 100. The portion of the box bottom plate 333 and the portion of the box top plate 331 that protrudes forward from the box shell 110 are opposite each other along the height direction of the box body 100. The box side panels 332 extend to the edge of the box bottom plate 333. The portion of the second plate portion 314 near the first plate portion 313 is located on the box bottom plate 333.

[0175] In some embodiments, the door control switch 500 can be disposed on the bottom plate 333, so that the door control switch 500 can be assembled together with the cover 330 on the top of the shell 110, which helps to improve assembly efficiency. Moreover, the electrical connection cable of the door control switch 500 can also be arranged below the cover 330, so that the wiring of the refrigerator is centralized and easy to maintain.

[0176] In some embodiments of this application, such as Figure 12 As shown, the hinge plate 310 also includes a connecting plate portion 315, which connects the first plate portion 313 and the second plate portion 314. The front portion of the first plate portion 313 bends downward to form the connecting plate portion 315; the connecting plate portion 315 bends forward to form the second plate portion 314. Thus, the first plate portion 313, the second plate portion 314, and the connecting plate portion 315 are integrally formed, making the hinge plate 310 structurally stable.

[0177] The protruding portion of the hinge plate 310 also includes a connecting plate portion 315. The portion of the cover 330 protruding from the front of the housing 100 covers the connecting plate portion 315 and a portion of the second plate portion 314.

[0178] The connecting plate portion 315 may be perpendicular to the first plate portion 313, and the connecting plate portion 315 may be inclined relative to the first plate portion 313. In some embodiments of this application, the connecting plate portion 315 abuts against the front of the housing 100. This arrangement helps to improve the positioning of the hinge plate 310 during installation and improves the convenience of installing the hinge plate 310.

[0179] In this embodiment, when the lids 330 have the same height, the distance between the first plate portion 313 and the top of the lid 330 is small because the first plate portion 313 is fixed to the top surface of the cabinet 100. The distance between the lid 330 and the top surface of the cabinet 100 on the side of the hinge plate 310 is larger to accommodate cables. Thus, while increasing the height of the cabinet 100 to expand the effective volume of the refrigerator, sufficient space is provided for the cables of the door control switch 500 by arranging them on the side of the hinge plate 310.

[0180] In some implementations, a large gap exists between the cover assembly 301 and the top surface of the housing 100 along the height direction of the housing 100, forming a second gap 372, which is located on the side of the first plate portion 313. The wiring gap 370 includes the second gap 372; the cable extends from above the second plate portion 314 to the second gap 372, and passes through the junction box portion 374 into the interior of the housing 110.

[0181] In this embodiment of the application, by providing a second interval 372 on the side of the first plate portion 313 to arrange the cable, the cable can be arranged on the side of the hinge plate 310, with sufficient wiring space.

[0182] Due to the increased height of the enclosure 100, the gap between the cover 330 and the first plate 313 is smaller, and the gap between the cover 330 and the top plate 111 is larger, forming a second gap 372, so that the cables are arranged on the side of the first plate 313, providing sufficient wiring space for the cables.

[0183] In some embodiments, combined with Figure 13 and Figure 16 The cover 330 may also include a wiring sidewall 334, which is disposed on the bottom surface of the top plate 331. The wiring sidewall 334, the top plate 331, and the top surface of the enclosure 100 together form a second partition 372, which can simplify the structure of the top plate 111 of the enclosure 110. Moreover, it allows the cables to be arranged according to a set trajectory, and can also restrict and constrain the cables, improving safety.

[0184] Combination Figure 14 and Figure 15 In some embodiments of this application, a hinge cover 350 is disposed above the second plate portion 314, forming a third interval 373. The portion of the cover 330 protruding from the front side of the housing 100 covers the second plate portion 314. Since the second plate portion 314 is lower than the top surface of the housing 100 relative to the first plate portion 313, a wiring interval 370 is formed above the second plate portion 314. The side panel 332 connecting the plate portion 315 and the front side of the cover 330 is spaced along the depth direction of the housing 100. Therefore, a wiring interval 370 is also formed between the second plate portion 314 and the portion of the cover 330 protruding from the front side of the housing 100.

[0185] like Figure 16 As shown, the cables for the electrical components on the door 200 can extend downwards towards the cover 330 via the third interval 373, then enter the second interval 372 via the side of the door control switch 500, and then enter the junction box 374. The electrical connection cable between the door control switch 500 and the main control board enters the junction box 374 via the second interval 372. Figure 16 The dashed line with an arrow indicates the general direction of the cable.

[0186] In some embodiments of this application, no electrical components are provided on the door 200. In this case, the hinge plate 310 does not need to have a bent connecting plate portion 315, i.e., the hinge plate 310 is as follows: Figure 5 As shown. The lid 330 is fixed to the top surface of the box body 100 and covers the top of part of the hinge plate 310, as can be seen from... Figures 11 to 12 The cover 330 has a wiring interval 370 formed below it. At least a portion of the wiring interval 370 is located on the side of the hinge plate 310, that is, a second interval 372 is formed on the side of the hinge plate 310 so that the electrical connection cable between the door switch 500 and the main control board enters the junction box 374 through the second interval 372.

[0187] Thus, without changing the overall height of the refrigerator, the height of the cabinet 100 is increased to expand the effective volume of the refrigerator. Although this compresses the space above the hinge plate 310, making it impossible to lay cables, a second interval 372 is provided on the side of the hinge plate 310 to lay cables, ensuring sufficient space for wiring.

[0188] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
