Description

Technical Field

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

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a appliance that keeps food or other items at a constant low temperature. With the development of science and technology and the improvement of people's living standards, refrigerators have become an indispensable appliance in life and production.

[0003] Typically, refrigerators have multiple shelves inside. Shelves are an important component of refrigerators, dividing the internal space into smaller compartments for storing food and maximizing the refrigerator's storage capacity. High-end refrigerators, for aesthetic reasons, often feature cantilever shelves. These shelves are supported by cantilever arms on both sides inside the refrigerator, allowing for height adjustment and easy installation and removal.

[0004] In related technologies, cantilever shelves, due to the need for detachable installation, suffer from power supply difficulties, lack self-illumination, and lack a sense of luxury and ambiance. When there are too many items on the shelves, the internal lighting of the refrigerator will be blocked by the shelves and the items on them, resulting in uneven lighting distribution and blind spots in some areas, making it inconvenient for users to access items. Utility Model Content

[0005] The purpose of this application is to provide a refrigerator whose shelves are luminous, thereby improving the lighting effect of the refrigeration compartment.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A refrigerator includes a cabinet, an inner liner, shelves, and a power supply assembly. The inner liner is disposed within the cabinet and forms a refrigeration compartment with a front opening. The shelves include a shelf body, a decorative strip, two supporting cantilever arms, and a light-emitting element. The shelf body is horizontally disposed within the refrigeration compartment and is constructed as a transparent plate. The decorative strip is disposed at the rear end of the shelf body. The two supporting cantilever arms are respectively disposed on the left and right walls of the refrigeration compartment to support the left and right ends of the shelf body, respectively. The light-emitting element is disposed on the decorative strip and has an electrical connection terminal. The power supply assembly includes a power supply box, a conductive element, and an elastic element. The power supply box is disposed on the side wall of the refrigeration compartment. The power supply box has an internal cavity. One end of the power supply box is spaced apart from the electrical connection end. The end face of the power supply box facing the electrical connection end has an opening that communicates with the cavity. A conductive element is movably disposed on the opening, with one end of the conductive element arranged outside the opening to form a conductive end. The conductive element is electrically connected to the power supply. An elastic element is disposed in the cavity and is connected to the end of the conductive element away from its conductive end. The elastic element applies an elastic force to the conductive element, causing it to move along the axial direction of the opening toward the light-emitting element, so as to press the conductive end against the electrical connection end, thereby connecting the power supply and the light-emitting element circuit.

[0008] The above-mentioned technical features have at least the following technical effects:

[0009] In this application, the power supply component includes a power supply box, a conductive element, and an elastic element. The power supply box is installed on the side wall of the refrigeration compartment. The conductive element and the elastic element are housed inside the power supply box. A decorative strip is installed at the rear end of the shelf body, and a light-emitting element is installed on the decorative strip. The light-emitting element is connected to the conductive element, allowing power to be supplied to the circuit of the light-emitting element, thereby causing the light-emitting element to emit light. This makes the shelf body illuminate and form a lighting source, improving the lighting effect of the refrigeration compartment. Simultaneously, the conductive element is connected to the elastic element, allowing the conductive element to be pressed against the electrical connection end of the light-emitting element by the elastic force of the elastic element. The conductive element can extend and retract along the axial direction of the opening, forming a telescopic contact power supply. This ensures that the light-emitting element is de-energized when the shelf body is removed from the refrigeration compartment and energized when the shelf body is installed in place inside the refrigeration compartment, thus meeting the detachable requirement of the cantilever shelf.

[0010] In one exemplary embodiment of this disclosure, two power supply components are provided, and the power supply boxes of the two power supply components are respectively disposed on the left side wall and the right side wall of the refrigeration chamber;

[0011] The electrical connection terminal includes a first electrical connection terminal disposed at the left end of the light-emitting element and a second electrical connection terminal disposed at the right end of the light-emitting element, wherein the polarities of the first electrical connection terminal and the second electrical connection terminal are opposite.

[0012] One end of each of the two power supply boxes is respectively spaced apart from the first electrical connection terminal and the second electrical connection terminal, and the conductive ends of the two conductive components respectively abut against the first electrical connection terminal and the second electrical connection terminal.

[0013] The above-mentioned technical features have at least the following technical effects:

[0014] By setting two power supply components, which are respectively installed on the left and right walls of the cooling room, the conductive ends of the two conductive parts in the two power supply components abut against the first electrical connection end and the second electrical connection end, so that the two power supply components are connected to the light-emitting component circuit. By setting two power supply components, the connection between the light-emitting component and the power supply components is tighter, and the power supply circuit of the light-emitting component is easier to set up.

[0015] In one exemplary embodiment of this disclosure, the inner wall of the accommodating cavity that abuts against the elastic member is configured as a conductive wall, and the conductive wall is electrically connected to the power source via a wire.

[0016] The above-mentioned technical features have at least the following technical effects:

[0017] In this application, by setting a conductive wall, electrical energy can be sequentially transferred from the conductive wall and the elastic element to the conductive element, which facilitates the setting of the circuit transmission loop.

[0018] In one exemplary embodiment of this disclosure, the power supply assembly further includes a first metal sheet, the accommodating cavity is open at one end away from the opening, the first metal sheet covers the opening of the accommodating cavity, the elastic member abuts against the first metal sheet at one end away from the conductive member, the inner sidewall of the first metal sheet constitutes the conductive wall, and the first metal sheet is electrically connected to the wire.

[0019] The above-mentioned technical features have at least the following technical effects:

[0020] By setting a separate first metal sheet to form the conductive wall, the first metal sheet can be removed first to open the cavity, which facilitates the installation of the elastic and conductive components into the accommodating area, while also simplifying the forming process of the conductive wall.

[0021] In one exemplary embodiment of this disclosure, the conductive element includes a cylindrical portion and a spherical portion. The cylindrical portion extends along the axial direction of the opening, one end of the cylindrical portion abuts against the elastic element, and the spherical portion is coaxially connected to the end of the cylindrical portion opposite to the elastic element. The outer surface of the spherical portion is configured as a sphere. The cylindrical portion is movably inserted into the opening, and the spherical portion abuts against the first electrical connection end or the second electrical connection end.

[0022] The cylindrical part is provided with a stop portion at one end away from the spherical part. The stop portion protrudes from the outer peripheral surface of the cylindrical part and can abut against the inner edge of the opening to prevent the cylindrical part from coming out of the opening.

[0023] The above-mentioned technical features have at least the following technical effects:

[0024] By incorporating a cylindrical section, the component can be inserted into the opening, guiding the movement of the conductive element. By incorporating a spherical section, the outer surface of which is spherical, when the shelf is installed, the left and right ends of the shelf body can move inward along the outer surface of the spherical section, thus pushing the conductive element into the opening and preventing interference between the conductive element and the shelf body.

[0025] In one exemplary embodiment of this disclosure, the light-emitting element includes a light-emitting strip and a second metal sheet. The light-emitting strip is disposed on the decorative strip and extends along the length direction of the decorative strip. The left and right ends of the light-emitting strip are connected to the second metal sheet to form the first electrical connection terminal and the second electrical connection terminal, respectively.

[0026] The above-mentioned technical features have at least the following technical effects:

[0027] The light-emitting component includes a light-emitting strip and a second metal sheet. The light-emitting strip emits light to illuminate the refrigeration compartment by directing light onto the shelf body. The second metal sheet is located at the left and right ends of the light-emitting strip to form a first electrical connection terminal and a second electrical connection terminal, respectively. This allows the light-emitting component to form an integrated light panel structure, simplifying the manufacturing process.

[0028] In one exemplary embodiment of this disclosure, a slot is provided at one end of the decorative strip facing the shelf body, and the rear end of the shelf body is engaged in the slot;

[0029] The decorative strip has a mounting cavity separated from the slot. The mounting cavity extends along the length of the decorative strip. The light strip is fixed in the mounting cavity. The first electrical connection end and the second electrical connection end are exposed at both ends of the mounting cavity. The light emitted by the light strip passes through the cavity wall of the mounting cavity and enters the shelf body.

[0030] The above-mentioned technical features have at least the following technical effects:

[0031] In this application, by providing a slot, the decorative strip can be snapped onto the shelf body, facilitating the installation and removal of the decorative strip. An installation cavity is formed within the decorative strip, which facilitates the fixing of the light-emitting component. The light emitted by the light-emitting component passes through the cavity wall and is directed onto the shelf body, causing the shelf body to emit light. This avoids the light source being visible from the front, enhancing the shelf's aesthetic appeal.

[0032] In one exemplary embodiment of this disclosure, the refrigerator further includes two end caps, with the two ends of the mounting cavity being open along its length. The two end caps are respectively positioned on both ends of the mounting cavity along its length, and the end caps have openings for the second metal sheet to be exposed.

[0033] The above-mentioned technical features have at least the following technical effects:

[0034] By setting an end cap, the mounting cavity can be sealed, but it can be opened when installing and removing the light-emitting component to facilitate the installation and removal of the light-emitting component. At the same time, the second metal plate is exposed, which does not affect the contact and conductivity between the second metal plate and the conductive component. The end cap can also restrict the position of the light-emitting component and the shelf body in the left and right directions.

[0035] In one exemplary embodiment of this disclosure, a plurality of shelves are spaced apart in the vertical direction in the refrigeration room, and a plurality of power supply components corresponding one-to-one with the shelves are spaced apart in the vertical direction on the left and right walls of the refrigeration room.

[0036] The above-mentioned technical features have at least the following technical effects:

[0037] By setting up multiple shelves, the refrigeration room can be divided into multiple independent storage spaces. Each shelf can hold items, and the number of shelves can be determined according to the distance between the shelves and the vertical height of the refrigeration room, thereby improving the storage function of the refrigeration room.

[0038] In one exemplary embodiment of this disclosure, the refrigerator further includes two hanging racks, which are respectively disposed on the left outer wall and the right outer wall of the inner liner. The hanging racks extend in the vertical direction and are provided with a plurality of support portions at intervals in the vertical direction. One end of each support portion extends into the refrigeration compartment. The support cantilever is detachably connected to at least one of the support portions to support the support cantilever.

[0039] The above-mentioned technical features have at least the following technical effects:

[0040] By setting up hangers to form a support part inserted into the refrigeration room to support the cantilever, the height of the support cantilever is adjustable and it can be detachably connected to the refrigeration room, so that the number of shelves in the refrigeration room can be flexibly set, and the space in the refrigeration room can be rationally allocated.

[0041] Beneficial effects:

[0042] In this application, the power supply component includes a power supply box, a conductive element, and an elastic element. The power supply box is installed on the side wall of the refrigeration compartment. The conductive element and the elastic element are housed inside the power supply box. A decorative strip is installed at the rear end of the shelf body, and a light-emitting element is installed on the decorative strip. The light-emitting element is connected to the conductive element, allowing power to be supplied to the circuit of the light-emitting element, thereby causing the light-emitting element to emit light. This makes the shelf body illuminate and form a lighting source, improving the lighting effect of the refrigeration compartment. Simultaneously, the conductive element is connected to the elastic element, allowing the conductive element to be pressed against the electrical connection end of the light-emitting element by the elastic force of the elastic element. The conductive element can extend and retract along the axial direction of the opening, forming a telescopic contact power supply. This ensures that the light-emitting element is de-energized when the shelf body is removed from the refrigeration compartment and energized when the shelf body is installed in place inside the refrigeration compartment, thus meeting the detachable requirement of the cantilever shelf.

Detailed Implementation

[0055] To make the objectives and implementation methods 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 exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0056] 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.

[0057] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0058] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0059] In refrigerator technology, cantilever shelves, due to the need for detachable installation, suffer from power supply difficulties, lack self-illumination, and lack a sense of luxury and ambiance. When there are too many items on the shelves, the internal lighting is blocked by the shelves and the items on them, resulting in uneven lighting distribution and blind spots, making it inconvenient for users to access items. To solve these problems, this application proposes a refrigerator design.

[0060] See Figures 1 to 4This embodiment provides a refrigerator for storing items at low temperatures. The refrigerator can also be a refrigerated display case, a refrigerated wine cabinet, or a freezer. The refrigerator may include a body (not shown in the figure), which is the external shell structure of the refrigerator. It may be a rectangular column structure with internal space for accommodating other components of the refrigerator.

[0061] In some embodiments, the refrigerator may include an inner liner 1 disposed within the refrigerator body. A cooling compartment 10 with a front opening is formed within the refrigerator body, and food is placed within the cooling compartment 10 for low-temperature preservation. Specifically, the inner liner 1 is constructed to form a cooling compartment 10 with a front opening. A door is closable on the front side of the refrigerator body to allow opening or closing of the cooling compartment 10 and accessing items within it. In this embodiment, the door is rotatably closed to the front side of the refrigerator body to open or close the inner liner 1.

[0062] In some embodiments, the refrigerator may include a refrigeration component. The refrigeration component transfers cold energy to air within an air duct assembly, providing cold air to the refrigeration compartment 10 so that cold air can be obtained within the air duct assembly. The air duct assembly may selectively communicate with the refrigeration compartment 10 to introduce air from the air duct assembly into the refrigeration compartment 10, thereby cooling the refrigeration compartment 10.

[0063] In some embodiments, the refrigeration compartment 10 may include a refrigerator compartment and a freezer compartment, and the air duct assembly can deliver cooling capacity to the refrigerator compartment and the freezer compartment respectively, so that the air in the air duct assembly can transfer the cooling capacity to the refrigerator compartment and the freezer compartment respectively, so as to maintain the refrigeration environment in the refrigerator compartment and the freezer compartment.

[0064] There may be a foam layer between the inner liner 1 and the cabinet. The foam layer is filled with foam material. The foam material surrounds the upper, lower, left, right and rear side walls of the refrigeration chamber 10, thereby insulating the refrigeration chamber 10 and maintaining the temperature of the refrigeration chamber 10.

[0065] In some embodiments, the cabinet doors include a freezer door for covering the freezer compartment and a refrigerator door for covering the refrigerator compartment. The refrigerator door is closable and covers the front of the refrigerator compartment and the variable temperature compartment for opening and closing the refrigerator compartment and the variable temperature compartment. The freezer door is closable and covers the front of the freezer compartment for opening and closing the freezer compartment. The freezer door and the refrigerator door are spaced apart in a left-right direction.

[0066] The refrigeration assembly is used to release heat from inside the refrigerator to the external environment and to provide cooling to the refrigeration compartment 10 to maintain a low-temperature environment inside the refrigeration compartment 10. The refrigeration assembly includes components such as a compressor, condenser, evaporator, and capillary tubes. The compressor, condenser, capillary tubes, and evaporator are connected in sequence, and the outlet of the evaporator is connected to the inlet of the compressor, thereby forming a channel for refrigerant circulation within the compressor, condenser, capillary tubes, and evaporator. In this embodiment, the evaporator is located inside the freezer compartment.

[0067] The air duct assembly is connected to the refrigeration chamber 10, allowing air to circulate between them. This transfers the cooling capacity from the air duct assembly to the refrigeration chamber 10, and vice versa. The low-temperature, low-pressure liquid refrigerant in the evaporator exchanges heat with the air duct assembly and is converted into a low-temperature, low-pressure gaseous refrigerant. This gaseous refrigerant is then transported to the compressor, where it is compressed into a high-temperature, high-pressure gaseous refrigerant.

[0068] The high-temperature, high-pressure gaseous refrigerant in the compressor is delivered to the condenser, where it releases heat to the surrounding environment, thus transforming into a low-temperature, high-pressure liquid refrigerant. This low-temperature, high-pressure liquid refrigerant then undergoes throttling and pressure reduction through capillary tubes, transforming into a low-temperature, low-pressure liquid refrigerant. Finally, this low-temperature, low-pressure liquid refrigerant is delivered to the evaporator and air duct assembly for heat exchange.

[0069] The specific structure and connection relationship of the refrigeration components are described in reference to the refrigeration components in related technologies, and will not be repeated here.

[0070] The air duct assembly is located inside the enclosure and provides cooling capacity to the cooling compartment 10. The specific structure and position of the air duct assembly are detailed in relevant technical documents and will not be repeated here.

[0071] In some embodiments, the shelf 2 may include a shelf body 20. The shelf body is the main structure of the shelf 2, and the shelf body 20 is horizontally disposed within the refrigeration chamber 10 for carrying items. The shelf body 20 is constructed as a transparent plate, such as a plate made of transparent glass or transparent plastic, so that light can pass through and illuminate the refrigeration chamber 10.

[0072] In some embodiments, the shelf 2 may further include two supporting cantilever arms 22, which are respectively disposed on the left and right side walls of the refrigeration chamber 10 to support the left and right ends of the shelf body 20, respectively. By providing supporting cantilever arms 22 to support the shelf body 20, the height of the shelf body 20 can be flexibly adjusted by adjusting the height of the supporting cantilever arms 22, thereby reasonably allocating the space of the refrigeration chamber 10.

[0073] See Figures 8 to 9In some embodiments, the refrigerator may include two hanging racks 5, which are respectively disposed on the left and right outer walls of the inner liner 1. The hanging racks 5 extend vertically to have a certain length in the vertical direction. The hanging racks 5 are provided with multiple support parts 50 at intervals in the vertical direction. One end of the support part 50 extends into the refrigeration compartment 10. The support cantilever 22 is detachably connected to at least one support part 50 to support the support cantilever 22. The support cantilever 22 can be selectively connected to support parts 50 of different heights, thereby realizing the height adjustment of the support cantilever 22.

[0074] In some embodiments, the support portion 50 can be a columnar structure that extends horizontally into the refrigeration chamber 10. A snap-fit ​​portion 220 can be provided at the rear end of the support cantilever 22, and the support portion 50 is snapped into the snap-fit ​​portion 220 to support and fix the support cantilever 22. The support cantilever 22 has a support surface along the front-to-back direction, and the bottom surfaces of the left and right ends of the shelf body 20 are supported on the support surface and can move back and forth along the support surface to facilitate the installation and removal of the shelf body 20.

[0075] In some embodiments, the snap-fit ​​portion 220 can be a latch provided at the rear end of the support cantilever 22. To improve stability, two snap-fit ​​portions 220 can be provided at intervals along the vertical direction of the rear end of the support cantilever 22. The two snap-fit ​​portions 220 are arranged opposite each other. When the support cantilever 22 is installed, the two adjacent support portions 50 are respectively snapped into the two latches to restrict the support cantilever 22 from flipping in the vertical direction, thereby stabilizing the support shelf body 20.

[0076] In some embodiments, the shelf 2 may include a decorative strip 21 and a light-emitting element 23. The decorative strip 21 is disposed at the rear end of the shelf body 20, and the light-emitting element 23 is disposed on the decorative strip 21. The light-emitting element 23 is capable of emitting light, and the light is diffusely reflected on the decorative strip 21, transmitting the light into the shelf body 20, thereby causing the shelf body 20 to emit light and provide an illumination effect.

[0077] In some embodiments, the decorative strip 21 can be a transparent or semi-transparent strip structure made of materials such as plastic or rubber, which serves to protect and cushion the shelf body 20, while also beautifying the shelf body 20. A slot 210 is provided at one end of the decorative strip 21 facing the shelf body 20, with the opening of the slot 210 facing the rear end of the shelf body 20. The slot 210 extends along the length of the decorative strip 21, and the rear end of the shelf body 20 is engaged in the slot 210, thereby securing it to the decorative strip 21 for easy assembly and disassembly.

[0078] In some embodiments, a mounting cavity 211, separated from the slot 210, is formed within the decorative strip 21. The mounting cavity 211 extends along the length of the decorative strip 21, thus extending in the same direction as the slot 210. The mounting cavity 211 can be located below or behind the slot 210. The mounting cavity 211 is used to fix the light-emitting element 23. The light-emitting element 23 is fixed within the mounting cavity 211, and the light emitted by the light-emitting element 23 passes through the cavity wall of the mounting cavity 211 and enters the shelf body 20, causing the shelf body 20 to emit light.

[0079] In some embodiments, the light-emitting element 23 may include a light-emitting strip 230 disposed on the decorative strip 21. Specifically, the light-emitting strip 230 may extend along the length direction of the decorative strip 21 and be fixed within the mounting cavity 211 to make the light emission of the shelf body 20 more uniform. The light-emitting strip 230 may include a circuit board and LEDs disposed on the circuit board. The circuit board forms an elongated structure along the length direction of the decorative strip 21 and is disposed within the mounting cavity 211. The LEDs are connected to the circuit board for emitting light. In this embodiment, the circuit board is placed horizontally within the mounting cavity 211 with the side of the circuit board containing the LEDs facing upwards, so that the light emission direction of the light-emitting element 23 is perpendicular to the shelf body 20. The light undergoes diffuse reflection within the decorative strip 21 to illuminate the shelf body 20, which can prevent the user from seeing the LEDs from the front of the shelf 2 and affecting the texture of the shelf 2.

[0080] In some embodiments, the light-emitting element 23 is provided with an electrical connection terminal to receive electrical energy transmitted from an external power source, thereby enabling the light-emitting element 23 to emit light. Specifically, the electrical connection terminal is disposed on the circuit board of the light-emitting strip 230 for connecting the circuit board and the external power source.

[0081] See also Figures 5 to 10 In some embodiments, the refrigerator may include a power supply component 3, which is disposed on the side wall of the refrigeration compartment 10. When the shelf 2 is installed in the preset position of the refrigeration compartment 10, the power supply component 3 is connected to the electrical connection terminal of the light-emitting element 23, thereby supplying power to the light-emitting element 23, causing the light-emitting element 23 to emit light and improving the lighting effect in the refrigeration compartment 10.

[0082] In some embodiments, the power supply assembly 3 may include a power supply box 30, which has an internal accommodating cavity 300. The external shape of the power supply box 30 may be a rectangular box or a circular box. The power supply box 30 is disposed on the side wall of the refrigeration chamber 10, with one end of the power supply box 30 spaced apart from the electrical connection end, so that the power supply box 30 does not interfere with the movement of the shelf 2 in the front-back direction. The end face of the power supply box 30 facing the electrical connection end has an opening 301 communicating with the accommodating cavity 300. The opening 301 may be a circular hole or a square hole.

[0083] In some embodiments, the power supply component 3 may further include a conductive element 31 electrically connected to the power supply. The conductive element 31 is movably disposed on the opening 301. One end of the conductive element 31 is disposed outside the opening 301 to form a conductive end. The conductive end is used to abut against the electrical connection end to conduct electricity, thereby electrically connecting the power supply and the light-emitting element 23, so that the power supply can supply electrical energy to the light-emitting element 23 and make the light-emitting element 23 emit light.

[0084] In some embodiments, the power supply assembly 3 may further include an elastic element 32. The elastic element 32 is disposed in the accommodating cavity 300 and connected to the end of the conductive element 31 opposite to its conductive end. The elastic element 32 applies an elastic force to the conductive element 31, causing it to move axially toward the light-emitting element 23 along the opening 301, thereby pressing the conductive end against the electrical connection end and connecting the power supply and the light-emitting element 23 circuit. By providing the elastic element 32, an elastic force is applied to the conductive element 31, allowing the conductive element 31 to extend and retract axially along the opening 301, forming a telescopic contact power supply.

[0085] When shelf 2 is installed in the refrigeration chamber 10, the electrical connection end of the light-emitting element 23 presses against the conductive end of the conductive element 31, causing the conductive element 31 to move axially along the opening 301 into the accommodating cavity 300 and press against the elastic element 32. At this time, the elastic element 32 applies an elastic force to the conductive element 31, causing it to move towards the light-emitting element 23. The conductive element 31 is firmly pressed against the electrical connection end by the elastic force of the elastic element 32, making the circuit between the conductive element 31 and the light-emitting element 23 conductive. When shelf 2 needs to be removed, it can be moved directly out of the refrigeration chamber 10, and the electrical connection end of the light-emitting element 23 and the conductive end of the conductive element 31 will disengage, thus de-energizing the light-emitting element 23 and facilitating the removal of shelf 2.

[0086] In some embodiments, the power supply box 30 may be disposed on the rear side wall of the cooling chamber 10, in which case the electrical connection terminal is disposed on the rear end of the light-emitting element 23. The power supply box 30 may also be disposed on the left or right side wall of the cooling chamber 10, in which case the electrical connection terminal is disposed on the left or right end of the light-emitting element 23.

[0087] In some embodiments, two power supply components 3 are provided, with power supply boxes 30 of the two power supply components 3 respectively disposed on the left and right sides of the refrigeration chamber 10. The two power supply boxes 30 can be symmetrically arranged about the shelf body 20. The electrical connection terminals may include a first electrical connection terminal 232 disposed on the left end of the light-emitting element 23 and a second electrical connection terminal 233 disposed on the right end of the light-emitting element 23. One end of the two power supply boxes 30 is respectively spaced apart from the first electrical connection terminal 232 and the second electrical connection terminal 233. The conductive ends of the two conductive elements 31 abut against the first electrical connection terminal 232 and the second electrical connection terminal 233 respectively, so that the two power supply components 3 are respectively connected to the circuit of the light-emitting element 23. By setting two power supply components 3, the connection between the light-emitting element 23 and the power supply components 3 is tighter, and the power supply circuit of the light-emitting element 23 is easier to set up. The first electrical connection terminal 232 and the second electrical connection terminal 233 have opposite polarities. For example, if the first electrical connection terminal 232 is the positive terminal, then the second electrical connection terminal 233 is the negative terminal.

[0088] In some embodiments, multiple shelves 2 are spaced apart vertically within the refrigeration chamber 10 to divide the refrigeration chamber 10 into multiple independent storage spaces. Each shelf 2 can hold items. The number of shelves 2 can be determined based on the distance between the shelves 2 and the vertical height of the refrigeration chamber 10, and can be one, two, three, or more. Multiple power supply components 3, corresponding one-to-one with the shelves 2, are spaced apart vertically on the left and right walls of the refrigeration chamber 10, so that each shelf 2 can be powered by the corresponding power supply component 3 to emit light, thereby improving the lighting effect within the refrigeration chamber 10.

[0089] In some embodiments, the light-emitting element 23 may further include a second metal sheet 231. The left and right ends of the light-emitting strip 230 are each connected to the second metal sheet 231 to form a first electrical connection terminal 232 and a second electrical connection terminal 233, respectively. The second metal sheet 231 can be directly soldered to the end of the circuit board of the light-emitting strip 230 to serve as the positive and negative electrodes of the light-emitting strip 230, so that the light-emitting element 23 is formed into an integrated lamp board structure.

[0090] In some embodiments, the refrigerator may further include two end caps 4. The mounting cavity 211 is open at both ends along its length to facilitate the installation of the light-emitting element 23 into the mounting cavity 211. The end caps 4 are respectively disposed on both ends of the mounting cavity 211 along its length, allowing the mounting cavity 211 to be closed. Simultaneously, the end caps 4 may have openings for the second metal sheet 231 to protrude, allowing the second metal sheet 231 to abut against the conductive element 31 to transfer electrical energy.

[0091] In some embodiments, the end cap 4 can be a semi-enclosed structure, having a first end wall 40 and a second end wall 41. The first end wall 40 abuts against the end face of the decorative strip 21 along its length to cover one end face of the mounting cavity 211 and the slot 210 along its length. The second end wall 41 is connected to the first end wall 40 at one end to fit against the side of the decorative strip 21. After the shelf body 20 is engaged in the slot 210, the left and right ends of the shelf body 20 abut against the first end wall 40 to limit the shelf body 20 in the left and right directions.

[0092] In some embodiments, the conductive element 31 may include a cylindrical portion 310. The cylindrical portion 310 extends along the axial direction of the opening 301, and one end of the cylindrical portion 310 abuts against the elastic element 32. It is movable and inserted into the opening 301 under the elastic force of the elastic element 32, so that after the shelf body 20 is installed in place, the conductive element 31 abuts against the electrical connection end.

[0093] In some embodiments, a base plate 212 may be detachably provided at the bottom of the decorative strip 21. The base plate 212 forms the bottom wall of the mounting cavity 211, and the light strip 230 can be fixed on the base plate 212 to facilitate the installation of the light strip 230.

[0094] In some embodiments, the conductive element 31 may include a spherical part 311, which is coaxially connected to one end of the cylindrical part 310 away from the elastic element 32. The outer surface of the spherical part 311 is configured as a sphere, so that when the shelf 2 is installed, interference with the shelf body 20 is avoided. The left and right ends of the shelf body 20 can move inward along the outer surface of the spherical part 311 and push the conductive element 31 into the opening 301.

[0095] In some embodiments, after the shelf 2 is installed in place, the spherical part 311 abuts against the first electrical connection end 232 or the second electrical connection end 233, so that the two conductive parts 31 are respectively connected to the circuit of the light-emitting part 23.

[0096] In some embodiments, a stop portion 312 is provided at one end of the cylindrical portion 310 away from the spherical portion 311. The stop portion 312 protrudes from the outer peripheral surface of the cylindrical portion 310 and may be annular. The stop portion 312 can abut against the inner edge of the opening 301 to restrict the cylindrical portion 310 from dislodging from the opening 301 and to limit the movement of the cylindrical portion 310 out of the opening 301. At this time, the elastic member 32 may be in a compressed state. When the first electrical connection end 232 or the second electrical connection end 233 abuts against the spherical portion 311, the compression of the elastic member 32 is greater and the elastic force of the elastic member 32 is greater. In turn, this makes the spherical portion 311 abut against the first electrical connection end or the second electrical connection end more tightly, and the circuit transmission is more stable.

[0097] In some embodiments, the elastic element 32 can be a compression spring, a disc spring, or a spring sheet, etc. In this embodiment, the elastic element 32 is a compression spring, one end of which abuts against the cylindrical portion 310, and the other end abuts against the inner wall of the accommodating cavity 300 opposite to the opening 301.

[0098] In some embodiments, the inner wall of the accommodating cavity 300 that abuts against the elastic member 32 is configured as a conductive wall, which can be made of a conductive material, such as copper, iron, or other metallic materials, to have conductivity. The conductive wall is electrically connected to a power source via a wire 35, thereby allowing electrical energy to be sequentially transferred through the power source, wire 35, conductive wall, elastic member 32, and conductive member 31 to the light-emitting element 23, enabling the light-emitting element 23 to emit light. It is understood that the elastic member 32 is made of a metallic material and is itself conductive.

[0099] In some embodiments, the conductive wall may be integrally formed with the accommodating cavity 300, or made of a conductive material alone. Alternatively, the conductive wall may be a separate component from the other inner walls of the accommodating cavity 300, with the conductive wall and the other inner walls of the accommodating cavity 300 surrounding each other to form the accommodating cavity 300.

[0100] In this embodiment, the accommodating cavity 300 is open at one end away from the aperture 301. The power supply component 3 may also include a first metal sheet 33, which covers the opening of the accommodating cavity 300, thereby closing the opening of the accommodating cavity 300 and forming the accommodating cavity 300 together with the other inner walls of the accommodating cavity 300. The inner sidewall of the first metal sheet 33 constitutes a conductive wall. The end of the elastic member 32 away from the conductive member 31 abuts against the first metal sheet 33. The first metal sheet 33 is electrically connected to the wire 35, and electrical energy is transferred from the first metal sheet 33 to the conductive member 31 through the elastic member 32. By setting a separate first metal sheet 33 to form a conductive wall, the first metal sheet 33 can be removed first to open the opening of the accommodating cavity 300, thereby facilitating the installation of the elastic member 32 and the conductive member 31 into the accommodating area, while also simplifying the forming process of the conductive wall.

[0101] In some embodiments, the first metal plate 33 can be screwed onto the power supply box 30 by a screw 34 to secure the first metal plate 33. At the same time, one end of the wire 35 can be connected to the screw 34 and pressed onto the first metal plate 33 by the head of the screw 34, thereby fixing the wire 35 and the first metal plate 33 and facilitating the transfer of electrical energy from the wire 35 to the first metal plate 33.

[0102] In some embodiments, the wire 35 can also be soldered to the first metal sheet 33, so that the wire 35 is fixed to the first metal sheet 33 and can transmit electrical energy to the first metal sheet 33.
