Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] With technological advancements, refrigerators are becoming increasingly versatile. A refrigerator consists of a refrigerator body and drawers movably mounted within the body. The inside of the drawers can be used to store food, etc. To illuminate or improve the freshness of the food, light-emitting elements are often installed within the drawers to emit light toward the food. However, light-emitting elements have complex structures and difficult to control. Utility Model Content

[0003] The embodiment of the present application provides a refrigerator that can solve the technical problems of complex structure of light-emitting elements in refrigerator drawers and complicated control methods of light-emitting elements.

[0004] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0005] A box body, wherein the box body is provided with a receiving cavity;

[0006] a drawer, movably disposed in the accommodating cavity;

[0007] a light-emitting circuit, comprising a light-emitting element, a contact member, and a circuit structure, wherein the light-emitting element is disposed in the drawer and is configured to emit light at least toward the inner side of the drawer;

[0008] The circuit structure is arranged in the accommodating cavity, the contact piece is arranged in the drawer, and the contact piece is connected to or separated from the circuit structure; when the drawer is located in the accommodating cavity, the contact piece is electrically connected to the circuit structure, and the light-emitting circuit is in a conductive state.

[0009] With the above technical solution, the housing is the main structure of the entire appliance, housing and protecting the internal components. The storage cavity is a space within the housing for drawers and other storage units. The storage cavity provides a closed and insulated environment, helping to maintain a low temperature and prolong the freshness of food. The drawers, as removable storage units within the refrigerator, can be moved within the storage cavity to facilitate access to food. Light-emitting elements within the drawers illuminate the space within the drawers, making it easier for users to find food. The light from the light-emitting elements shines directly on the food, providing a freshness-preserving or sterilizing effect. The circuit structure is installed in the storage cavity, while the contacts are mounted on the drawers. This design automatically connects and disconnects the light-emitting circuit when the drawer is pulled out or pushed in, ensuring that the light-emitting elements operate only when needed, thus saving energy. When the drawer is fully inserted into the storage cavity, the contacts electrically connect to the circuit structure, activating the light-emitting circuit and activating the light-emitting elements. This design ensures that the light-emitting elements operate only when the drawer is fully closed, preventing unnecessary power consumption and harm to the human body caused by the light used for freshness preservation or sterilization. With such an arrangement, the structure of the light-emitting circuit is relatively simple, and the opening and closing control of the light-emitting element can be achieved by changing the position of the drawer in the accommodating cavity, which is relatively convenient.

[0010] In some embodiments of the present application, on the drawer, the number of the contact members is set to two;

[0011] The circuit structure is provided with two abutting portions, the two abutting portions are provided on the inner wall of the accommodating cavity, and the two abutting portions are provided correspondingly to the two contact members;

[0012] When the drawer is in a pushed-in state, the drawer is located in the accommodating cavity, and the contact piece is electrically connected to the corresponding abutting portion; when the drawer is in a pulled-out state, at least part of the drawer is located outside the accommodating cavity, and the contact piece is separated from the corresponding abutting portion.

[0013] The two contacts on the drawer correspond to the two abutments of the circuit structure. When the drawer is pushed into the receiving cavity, the two contacts accurately contact the two abutments, forming a reliable electrical connection. This ensures that the light-emitting circuit is in a conductive state and the light-emitting element can function normally, providing illumination inside the drawer. When the drawer is pulled out of the receiving cavity, the contacts on the drawer separate from the abutments on the inner wall of the receiving cavity, disconnecting the light-emitting circuit and stopping the light-emitting element. This arrangement improves the reliability of the circuit connection and ensures that the light-emitting element only operates when needed, saving energy and improving the user experience.

[0014] In some embodiments of the present application, the number of the drawers is set to multiple, and the contact members of the multiple drawers are connected in parallel.

[0015] Multiple drawers within a refrigerator can be used to partition the storage compartment, allowing users to categorize and store different types of food, improving the refrigerator's storage capacity and orderliness. By connecting the contacts of multiple drawers in parallel, each drawer's contact can be individually connected to the circuit structure, allowing each drawer's contact to operate independently. With this arrangement, when a drawer is withdrawn, its contact is disconnected from the circuit structure, and its light-emitting element ceases operation, but this does not affect the operation of the light-emitting elements in other drawers. Furthermore, even if a contact malfunction occurs in one or more drawers, the normal operation of the other drawers will not be affected.

[0016] In some embodiments of the present application, the number of the drawers is set to be multiple, and the contact members of the multiple drawers are connected in series;

[0017] When all the drawers are in the pushed-in state, the drawers are located in the accommodating cavity, the contact members are electrically connected in sequence, and the light-emitting circuit is in a connected state; when at least one of the drawers is in the pulled-out state, at least part of the drawer in the pulled-out state is located outside the accommodating cavity, and the light-emitting circuit is in a disconnected state.

[0018] Multiple drawers in a refrigerator can partition the storage cavity, allowing users to sort and store different types of food, improving the refrigerator's storage capacity and orderliness. The contacts of multiple drawers are connected in series, so the lighting circuit is activated only when the contacts of all drawers are connected. This arrangement disconnects the lighting circuit and stops the light-emitting element when any drawer is pulled out. The light-emitting element only activates when all drawers are fully inserted into the storage cavity, saving energy and avoiding unnecessary power consumption.

[0019] In some embodiments of the present application, on the drawer, the number of the contact members is set to two; the circuit structure is provided with two abutting portions, and the two abutting portions are provided on the inner wall of the accommodating cavity;

[0020] Among the multiple drawers, the drawer connected to the abutting portion is set as a first drawer; one of the contact members of the first drawer is electrically connected to the abutting portion, and another contact member of the first drawer is electrically connected to the contact member of the adjacent drawer.

[0021] With this arrangement, among the multiple drawers, only the drawer closest to the inner wall of the storage chamber, i.e., the first drawer, is directly connected to the abutment on the inner wall of the storage chamber. This simplifies circuit design and ensures that the starting and ending points of the circuit are clearly defined. A contact in the first drawer is electrically connected to an abutment on the inner wall of the storage chamber, ensuring that the starting point of the circuit can connect to a power source to provide power to the light-emitting circuit. Another contact in the first drawer is electrically connected to a contact in an adjacent drawer. Through this series connection, the circuit can pass through the contacts of each drawer in sequence, forming a complete circuit.

[0022] In some embodiments of the present application, the contact member includes a base, and an abutting member and a conductive member provided on the base;

[0023] The base is arranged on the drawer, and the abutment member is electrically connected to the light emitting element via the conductive member;

[0024] The abutment member includes a first contact portion and a second contact portion connected to each other, wherein the first contact portion is located inside the base, and the second contact portion is located outside the drawer, and the second contact portion is at least used for electrically connecting to the circuit structure.

[0025] The base of the contact provides a stable mounting platform. Mounted on the drawer, the base allows the contact to move with the drawer, facilitating circuit connection and disconnection. The first contact portion of the abutment can reliably connect electrically to the conductive member within the base, thereby electrically connecting to the light-emitting element through the conductive member. The second contact portion of the abutment can electrically connect to the circuit structure on the inner wall of the accommodating cavity, completing the circuit closure and enabling current to be transferred from the power source through the abutment and conductive member to the light-emitting element. This arrangement provides a clear contact structure, facilitates manufacturing and assembly, and improves the reliability and stability of the light-emitting circuit.

[0026] In some embodiments of the present application, the second contact portion is provided on a side wall of the drawer, and the second contact portion can move closer to or away from the side wall of the drawer;

[0027] When the drawer is located in the accommodating cavity, the contact member is electrically connected to the circuit structure via the second contact portion, and the second contact portion is in a compressed state;

[0028] And / or, the first contact portion can be extended or retracted in a direction approaching or moving away from the conductive member, and when the first contact portion is electrically connected to the conductive member, the first contact portion is in a compressed state.

[0029] The position of the second contact portion is variable when the drawer moves, which helps to ensure reliable contact with the circuit structure and reduce the possibility of poor contact. When the drawer is fully pushed into the accommodating cavity, the second contact portion is in a compressed state and has a rebound force. Under the action of the rebound force of the second contact portion, it can maintain stable contact with the circuit structure. When the first contact portion is in a compressed state when electrically connected to the conductive part, the first contact portion also has a rebound force. Under the action of the rebound force of the first contact portion, it can maintain stable contact with the conductive part. With this arrangement, when the drawer is located in the accommodating cavity, it can ensure reliable electrical connection between the contact member and the circuit structure, improve the stability of the circuit, and thus enhance the user experience and the overall performance of the refrigerator.

[0030] In some embodiments of the present application, the first end of the second contact portion is connected to the first contact portion, and the second contact portion is located outside the drawer;

[0031] The second contact portion is provided on a side wall of the drawer, a first end of the second contact portion is close to a rear side of the drawer, and a second end of the second contact portion is close to a front side of the drawer.

[0032] In this arrangement, the second contact portion is mounted on the outside of the drawer and connected to the first contact portion. The second contact portion can then be electrically connected to the circuit structure within the accommodating cavity and transmit current to the light-emitting element via the first contact portion. The first end of the second contact portion is connected to the first contact portion, and the second end of the second contact portion is a free end located near the front of the drawer. Therefore, when the drawers move relative to each other, the second end of the second contact portion can smoothly abut or contact the second end of the second contact portion on another adjacent drawer, thereby preventing the second contact portions of the two adjacent drawers from interlocking and affecting the smooth movement of the drawers.

[0033] In some embodiments of the present application, the base is provided with a clamping block, the drawer is provided with a clamping slot, and the clamping block is inserted into the clamping slot;

[0034] And / or, the base is provided with a receiving groove, the base is provided with a mounting cover, and the mounting cover is arranged in the receiving groove; the mounting cover and the base form a through opening, and the through opening is at least used to pass the abutment member.

[0035] The base is firmly mounted on the drawer through the cooperation of the snap-in block and the snap-in groove, which can prevent the base from being displaced when the drawer is moved, thereby improving the stability and reliability of the structure. The mounting cover provided on the base provides a protective structure to ensure that the abutment and the conductive member can be safely installed in the base, preventing them from being damaged by the external environment, thereby improving the reliability of the circuit connection. The mounting cover and the base form a through opening for the abutment to pass through, ensuring that the abutment can be connected to the external circuit structure through the through opening to form a complete circuit, while protecting the abutment and the conductive member located in the base from being affected by the external environment. Such a setting improves the reliability and stability of the circuit connection and ensures that the light-emitting circuit of the refrigerator can operate normally.

[0036] In a second aspect, an embodiment of the present application provides a refrigerator, comprising a housing, a drawer, and a light-emitting circuit; the housing is provided with a receiving cavity, and the drawer is movably disposed in the receiving cavity;

[0037] The light-emitting circuit includes a light-emitting element and a contact member; the light-emitting element is arranged in the drawer, and the light-emitting element is at least used to emit light toward the inner side of the drawer, and the contact member is at least used to control the on and off of the light-emitting circuit;

[0038] When the drawer is in a pushed-in state, the contact piece puts the light-emitting circuit in a connected state, and the contact piece is at least used to control the light-emitting element to emit light; when the drawer is in a pulled-out state, the contact piece puts the light-emitting circuit in an open state, and the light-emitting element does not emit light.

[0039] By adopting the above technical solution, a storage cavity is provided in the cabinet, and the drawer can be moved within the storage cavity, making it convenient for users to store and retrieve food, thereby improving the convenience and flexibility of the refrigerator. By providing a light-emitting circuit on the refrigerator, the refrigerator drawer can be equipped with at least one of the following functions: lighting, preservation, and sterilization, thereby improving the functionality and practicality of the refrigerator. The operating state of the light-emitting element is controlled by a contact, ensuring that the light-emitting element only operates when the drawer is fully closed, preventing unnecessary power consumption. When the drawer is pulled out, the items inside the drawer are easy to observe and the light-emitting element stops operating, which helps save energy and prevents the light used for preservation or sterilization from shining on the human body, avoiding harm to the user. It can be seen that the structure of the light-emitting circuit is relatively simple, and the opening and closing control of the light-emitting element can be achieved by changing the position of the drawer within the storage cavity, which is relatively convenient.

[0070] As described in the background art, the refrigerator in the related art includes a box body and a drawer movably arranged on the box body, and the inner side of the drawer can be used to place food, etc. In order to illuminate or improve the fresh-keeping effect of the drawer on food, a light-emitting element can usually be set in the drawer to emit light toward the food. For example, in the prior art, the light-emitting element can be connected by plugging in a plug and a socket. This requires installing a guide rail on the surface of the drawer or inside the refrigerator so that the drawer slides along a preset track in the refrigerator to facilitate the alignment and plugging of the plug and the socket; or, the light-emitting element installed in the drawer often requires a special circuit arrangement to avoid pulling or curling of the circuit during the process of pushing and pulling the drawer, which causes instability in the circuit where the light-emitting element is located. It can be seen that the structure of the light-emitting element in the prior art is complex and the control method of the light-emitting element is cumbersome.

[0071] In view of this, an embodiment of the present application provides a refrigerator, comprising: a box body, the box body being provided with a receiving cavity for placing drawers and other storage units; a drawer being movably arranged in the receiving cavity to facilitate a user to store and retrieve food;

[0072] Compared with the light-emitting elements in the related art, the refrigerator provided in the embodiment of the present application also includes a light-emitting circuit, which includes a light-emitting element, a contact and a circuit structure. The light-emitting element is arranged in the drawer, and the light-emitting element is at least used to emit light toward the inner side of the drawer; the circuit structure is arranged in the accommodating cavity, and the contact is arranged in the drawer, and the contact is connected or separated from the circuit structure; when the drawer is pulled out or pushed into the accommodating cavity, the circuit can be automatically connected or disconnected to ensure that the light-emitting element only works when needed, thereby saving energy.

[0073] When the drawer is fully inserted into the receiving cavity, the contact element electrically connects to the circuit structure, the light-emitting circuit is in a conductive state, and the light-emitting element begins to operate. This ensures that the light-emitting element operates only when the drawer is fully closed, preventing unnecessary power consumption and also preventing harm to the human body caused by the light used for preservation or sterilization. This arrangement simplifies the structure of the light-emitting circuit and conveniently controls the opening and closing of the light-emitting element by simply changing the position of the drawer within the receiving cavity.

[0080] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0081] Reference Figure 1-Figure 2 , an embodiment of the present application provides a refrigerator, including a cabinet 100. The cabinet 100 is the main structure of the entire refrigerator, which can accommodate and protect the internal components of the refrigerator.

[0082] The box body 100 may be provided with a receiving cavity 110. The receiving cavity 110 is a space inside the box body 100 for placing the drawer 120 and other storage units. The receiving cavity 110 can provide a closed and heat-insulating environment, which helps to maintain a low temperature inside, thereby extending the shelf life of the food.

[0083] For example, an inner shell 101 may be disposed within the housing 100. The inner shell 101 may be configured to form a receiving cavity 110. A certain gap may be formed between the inner shell 101 and the outer wall of the housing 100, which may be used to install functional components of the refrigerator and to fill a thermal insulation structure to maintain the temperature inside the refrigerator.

[0084] It should be noted that the box body 100 also has a left side, a right side, an upper side, a lower side, a front side and a rear side.

[0085] The box 100 faces Figure 1 The side in the X direction is the right side of the box 100. The box 100 is away from Figure 1The side in the X direction is the left side of the box 100. The box 100 faces Figure 1 The side in the Z direction is the upper side of the box body 100. The box body 100 is away from Figure 1 The side in the Z direction is the lower side of the box body 100. The box body 100 faces Figure 1 The side in the Y direction is the front side of the box 100. The box 100 is facing away from Figure 1 The side in the Y direction is the rear side of the box body 100 .

[0086] A door 130 may be provided on the front side of the box body 100 .

[0087] The door 130 can be rotatably connected to the housing 100. The door 130 can at least be used to open and close the accommodating chamber 110. The door 130 can be used to form a relatively closed space inside the housing 100, thereby maintaining a relatively constant temperature in the accommodating chamber 110 and reducing the temperature rise rate in the accommodating chamber 110.

[0088] There may be a plurality of door bodies 130 , each of which corresponds to a different area of the accommodating chamber 110 to open and close the corresponding area of the accommodating chamber 110 .

[0089] For example, the plurality of doors 130 may be distributed along the up-down direction on the front side of the box body 100 .

[0090] Alternatively, the plurality of doors 130 may be distributed along the left-right direction on the front side of the box body 100. Furthermore, the plurality of doors 130 may be distributed in a combination of the up-down direction and the left-right direction on the front side of the box body 100.

[0091] Reference Figure 3-Figure 6 The box body 100 may be provided with a drawer 120. The drawer 120 is a storage unit in the refrigerator, which can divide the accommodating cavity 110 into a plurality of storage spaces so that food can be placed in different storage spaces.

[0092] The drawer 120 may be provided with a front portion 121. The front portion 121 is located on a side of the drawer 120 facing the front side of the box body 100. The front portion 121 can be convenient for a user to hold in hand, so that the user can operate the drawer 120.

[0093] The drawer 120 may further be provided with a surrounding frame 122. The surrounding frame 122 and the front side portion 121 are distributed around the drawer 120 to enclose a space for storing food.

[0094] The drawer 120 is movably disposed in the accommodating cavity 110. The drawer 120 can be moved in the accommodating cavity 110, and the user can conveniently store and retrieve food, thereby improving the convenience and flexibility of using the refrigerator.

[0095] A mounting housing 102 for mounting a drawer 120 can be disposed within the accommodating cavity 110. The mounting housing 102 encloses a chamber 103 capable of accommodating the drawer 120. The drawer 120 is located within the chamber 103 and is movable along the front and rear sides of the housing 100. The mounting housing 102 protects the drawer 120 and also guides its movement.

[0096] Reference Figure 4-Figure 5 The housing 100 may be provided with a lighting circuit. The lighting circuit may be a system integrating a light-emitting element 200, a contact 300, and a circuit structure 400. When the lighting circuit is in a conducting state, the light-emitting element 200 is powered and can emit light to meet the use requirements of the refrigerator.

[0097] The light emitting element 200 may be disposed in the drawer 120. The light emitting element 200 is configured to emit light at least toward the inner side of the drawer 120. Different light emitting elements 200 emit different light, which can illuminate, preserve, or sterilize the environment within the drawer 120.

[0098] For example, the light emitting element 200 can be configured as a common lighting lamp. When the light emitting element 200 is in the on state, the light emitting element 200 can at least achieve a lighting effect inside the drawer 120 .

[0099] The light emitting element 200 can be configured as a photosynthetic fresh-keeping lamp. When the light emitting element 200 is in the on state, the light emitting element 200 can achieve a fresh-keeping effect for food and also provide lighting for the interior of the drawer 120.

[0100] The light emitting element 200 can be configured as an ultraviolet lamp. When the light emitting element 200 is in the on state, the light emitting element 200 can achieve a sterilization effect inside the drawer 120 and also provide lighting for the inside of the drawer 120.

[0101] It can be understood that a photosynthetic fresh-keeping lamp is a device that uses the principle of photosynthesis for fresh-keeping treatment. Its main principle is to use the light energy of photosynthesis to activate the cell activity in food and promote the growth and metabolism of microorganisms in food, thereby achieving the effect of fresh-keeping.

[0102] Ultraviolet lamps disinfect using ultraviolet light of a specific wavelength (primarily the UVC band, at 253.7nm). This wavelength of ultraviolet light has the strongest bactericidal power, destroying the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial cells, preventing them from replicating and reproducing normally, thereby achieving a sterilizing and disinfecting effect.

[0103] A power supply module may be provided in the refrigerator. The light-emitting circuit may be electrically connected to the power supply module. By controlling the power supply module, the time during which the light-emitting circuit is in the on state may be controlled, thereby flexibly adjusting the operating timing and operating duration of the light-emitting element 200.

[0104] For example, when the light-emitting element 200 only provides lighting, the power supply module can be set to start when the door body 130 is opened to power the light-emitting circuit, so that when the light-emitting circuit is in a conductive state, the light-emitting element 200 emits bright light for illumination; and stop running when the door body 130 is closed, and stop powering the light-emitting circuit to avoid unnecessary power loss.

[0105] When the light-emitting element 200 also provides a preservation or sterilization function, the power supply module can be set to start when the door body 130 is opened to power the light-emitting circuit, and continue to run for a certain time after the door body 130 is closed to ensure the irradiation time required for preservation or sterilization.

[0106] The circuit structure 400 may be disposed in the accommodating cavity 110 . As a connection point on the light-emitting circuit, the circuit structure 400 is stably fixed at a position in the accommodating cavity 110 , and can be easily electrically connected to the contact member 300 .

[0107] The circuit structure 400 may be disposed on the mounting shell 102. The circuits of the circuit structure 400 may be arranged in the gap between the mounting shell 102 and the inner shell 101 to hide the circuits of the circuit structure 400, thereby improving aesthetics and safety.

[0108] The contact 300 can be provided in the drawer 120. The contact 300 can move with the movement of the drawer 120, thereby connecting or disconnecting the contact 300 and the circuit structure 400. When the drawer 120 is pulled out or pushed in, the lighting circuit can be automatically connected or disconnected, which can simplify the control process of the lighting circuit.

[0109] When drawer 120 is located within accommodating cavity 110, contact member 300 is electrically connected to circuit structure 400, and the light-emitting circuit is in a conductive state. When the light-emitting circuit is in a conductive state, light-emitting element 200 can operate, emitting light that illuminates the interior of drawer 120 to achieve lighting, freshness preservation, or sterilization effects.

[0110] The contact 300 may be disposed on the front side 121 of the drawer 120. The light emitting element 200 may be disposed on the front side 121 of the drawer 120. The light emitting element 200 and the contact 300 are both located on the front side 121 of the drawer 120 and are close to each other, which facilitates electrical connection.

[0111] By adopting the above-mentioned technical solution, when the drawer 120 is fully pushed into the accommodating cavity 110, the contact member 300 is electrically connected to the circuit structure 400, the light-emitting circuit is in a conducting state, and the light-emitting element 200 starts to work. This design ensures that the light-emitting element 200 will only work when the drawer 120 is fully closed, preventing unnecessary power consumption and preventing the light used for preservation or sterilization from causing harm to the human body.

[0112] With such an arrangement, the structure of the light-emitting circuit is relatively simple, and the opening and closing control of the light-emitting element 200 can be achieved by changing the position of the drawer 120 in the accommodating cavity 110, making the control process of the light-emitting circuit relatively convenient.

[0113] In some possible implementations, when the drawer 120 is in the pushed-in state, the contact member 300 can put the light-emitting element 200 in a passage state, and the light-emitting element 200 can be used to emit light toward the inner side of the drawer 120 .

[0114] For example, when the drawer 120 is in the pulled-out state, the contact member 300 can put the light emitting element 200 in an off-circuit state, and the light emitting element 200 does not emit light.

[0115] It should be noted that when the light emitting element 200 is in the on state, the power supply module can supply power to the light emitting element 200 through the light emitting circuit, and the light emitting element 200 can continuously emit light.

[0116] For example, when the light emitting element 200 can emit light, the light emitting element 200 is in the on state. When the light emitting element 200 can be electrically connected to the power supply module and there is a potential difference between the two ends of the light emitting element 200, the light emitting element 200 is in the on state.

[0117] When the light emitting element 200 is in the off-circuit state, the entire light emitting circuit is in the off-circuit state, the power supply module cannot supply power to the light emitting element 200 through the light emitting circuit, and the light emitting element 200 cannot emit light.

[0118] Reference Figure 7 In some possible implementations, the number of the contact members 300 on the drawer 120 can be set to two. The two contact members 300 are electrically connected to the circuit structure 400 respectively, so as to realize the input and output of current.

[0119] The circuit structure 400 can be provided with two abutting portions 410. The two abutting portions 410 are disposed on the inner wall of the accommodating cavity 110. The two abutting portions 410 are disposed correspondingly to the two contacts 300. This design ensures that when the drawer 120 is pushed into the accommodating cavity 110, the two contacts 300 can accurately contact the two abutting portions 410, forming a reliable electrical connection.

[0120] When the drawer 120 is pushed in, it is located within the accommodating cavity 110, and the contact 300 is electrically connected to the corresponding abutment 410. When the drawer 120 is fully inserted into the accommodating cavity 110, the contact 300 on the drawer 120 aligns with and connects to the abutment 410 on the inner wall of the accommodating cavity 110. The lighting circuit is in a conductive state, and the light-emitting element 200 can function normally, illuminating the interior of the drawer 120 so that the user can observe the items placed in the drawer 120, and can also be used to provide freshness preservation or sterilization functions.

[0121] When the drawer 120 is pulled out, at least a portion of the drawer 120 is located outside the accommodating cavity 110, and the contact 300 is separated from the corresponding abutment 410. When the drawer 120 is fully or partially pulled out of the accommodating cavity 110, the contact 300 on the drawer 120 deviates from the abutment 410 on the inner wall of the accommodating cavity 110, and the contact 300 and the abutment 410 are separated. The light circuit is disconnected, and the light-emitting element 200 stops working. This prevents the light used for preservation or sterilization from causing harm to the human body and also saves electricity.

[0122] By adopting the above technical solution, the structure is relatively simple, and the convenience of connecting the contact member 300 and the circuit structure 400 and the sensitivity of disconnecting the contact member 300 and the circuit structure 400 are achieved. As the user pushes and pulls the drawer 120, the light-emitting circuit can be turned on and off, and the control of the light-emitting element 200 is relatively convenient.

[0123] In some possible implementations, the number of drawers 120 can be set to multiple. Multiple drawers 120 can partition the accommodating cavity 110, allowing users to classify and store different types of food, thereby improving the efficiency and convenience of using the refrigerator.

[0124] For example, the contacts 300 of a plurality of drawers 120 may be connected in parallel.

[0125] The contact members 300 connected in parallel, each of which can be connected to the circuit structure 400 , can ensure that the contact member 300 of each drawer 120 can work independently to control the light-emitting element 200 connected to the contact member 300 .

[0126] When any drawer 120 is pushed into the accommodating cavity 110, the contact 300 of that drawer 120 is electrically connected to the circuit structure 400, and the light-emitting element 200 begins to operate. When any drawer 120 is pulled out, the contact 300 of that drawer 120 is disconnected from the circuit structure 400, and the light-emitting element 200 stops operating. Even if a contact 300 of one drawer 120 fails, it will not affect the normal operation of the other drawers 120.

[0127] By adopting the above technical solution, not only the partition storage function of the refrigerator is increased, but also the lighting system of each drawer 120 is ensured to work independently, thereby improving the user experience and the overall performance of the refrigerator.

[0128] Reference Figure 8-Figure 9 In some possible implementations, the number of drawers 120 can be set to multiple. Multiple drawers 120 can partition the accommodating cavity 110, allowing users to classify and store different types of food, thereby improving the efficiency and convenience of using the refrigerator.

[0129] For example, the contacts 300 of a plurality of drawers 120 may be connected in series.

[0130] The design of series connection ensures that the contact members 300 of all drawers 120 must be in a connected state at the same time so that the lighting circuit can be in a pass state. This design can ensure that the light emitting element 200 will only work when all drawers 120 are fully pushed in, which can save energy.

[0131] When all drawers 120 are pushed in, they are located within the accommodating cavity 110, the contacts 300 are electrically connected, and the lighting circuit is in a conductive state. Only when all drawers 120 are fully closed will the light-emitting element 200 operate, preventing any drawer 120 from operating when it is not fully closed, thereby avoiding unnecessary power consumption.

[0132] When at least one drawer 120 is in the pulled-out state, at least a portion of the drawn-out drawer 120 is located outside the accommodating cavity 110 , and the lighting circuit is in an off-circuit state.

[0133] When at least one drawer 120 is pulled out of the accommodating cavity 110, the lighting circuit is in an off-circuit state and the light-emitting element 200 stops working, which can ensure that when any drawer 120 is pulled out, the lighting circuit is disconnected and the light-emitting element 200 stops working to save energy.

[0134] By adopting the above technical solution, not only the partitioned storage function of the refrigerator is increased, but also it is ensured that the light-emitting element 200 can work when all drawers 120 are closed, saving energy while also having a reminder function. When the light-emitting element 200 is not lit, it can remind the user that some drawers 120 have not been returned to their original positions, thereby improving the overall performance of the refrigerator.

[0135] Reference Figure 8-Figure 9 In some possible implementations, the number of contacts 300 on the drawer 120 is set to two. By providing two contacts 300, one of which is used to connect to the circuit structure 400, and the other contact 300 is used to connect to the contact 300 of the adjacent drawer 120, the drawers 120 are connected in series.

[0136] The circuit structure 400 is provided with two abutting portions 410, which are provided on the inner wall of the accommodating cavity 110. This design ensures that when the drawer 120 is fully pushed into the accommodating cavity 110, the contact members 300 on the drawer 120 near the inner wall of the accommodating cavity 110 can accurately contact the two abutting portions 410, forming a reliable electrical connection.

[0137] Reference Figure 11 The circuit structure 400 is provided with a mounting seat 420. The abutting portion 410 is mounted on the mounting seat 420. The mounting seat 420 can be mounted on the mounting shell 102 through a snap-fit structure. The mounting seat 420 can provide a mounting position for the abutting portion 410, so that the position of the abutting portion 410 is stable.

[0138] Among the multiple drawers 120, the drawer 120 connected to the abutment portion 410 is provided as a first drawer. It will be appreciated that there are two first drawers in the multiple drawers 120, each located adjacent to the accommodating cavity 110. By providing a first drawer, the contact member 300 therein directly connects to the abutment portion 410, simplifying the design of the lighting circuit and making the starting and ending points of the lighting circuit clear.

[0139] One of the contacts 300 in the first drawer is electrically connected to the abutment portion 410. Another contact 300 in the first drawer is electrically connected to the contact 300 in the adjacent drawer 120. This series connection ensures that the circuit can connect the contacts 300 in each drawer 120 in sequence, forming a complete circuit.

[0140] By adopting the above technical solution, the contact piece 300 of the first drawer facing the inner wall of the accommodating cavity 110 is electrically connected to the abutment portion 410, and the contact piece 300 of the first drawer facing another drawer 120 is electrically connected to the contact piece 300 on the drawer 120, thereby realizing the series connection of multiple drawers 120. This series connection method has a simple structure and is easier to implement, which facilitates the closing or disconnection of the light-emitting circuit.

[0141] Reference Figure 10-14 In some possible embodiments, the contact 300 may include a base 310. The base 310 is disposed on the drawer 120. The base 310 can provide a stable mounting platform on the drawer 120. This ensures that the overall structure of the contact 300 is stable and can move with the drawer 120, facilitating the connection or disconnection of the lighting circuit.

[0142] The contact member 300 may further include an abutment member 320 disposed on the base 310. The abutment member 320 is electrically connected to the light emitting element 200. As a current conducting component, the abutment member 320 can transfer the current of the power supply to the light emitting element 200 when the light emitting circuit is in a conducting state.

[0143] The abutment member 320 includes a first contact portion 321 and a second contact portion 322. The provision of the first contact portion 321 and the second contact portion 322 allows for functional division of different portions of the abutment member 320, facilitating simultaneous electrical connection of the abutment member 320 to both the light-emitting element 200 on the inner side of the base 310 and the circuit structure 400 on the outer side of the drawer 120, thereby ensuring smooth conduction of current.

[0144] The first contact portion 321 is located on the inner side of the base 310 , and the second contact portion 322 is located on the outer side of the drawer 120 . The second contact portion 322 is at least used for electrically connecting to the circuit structure 400 .

[0145] The first abutment portion 410 is disposed on the inner side of the base 310 and can establish a reliable electrical connection with the light-emitting element 200. The second contact portion 322 is disposed on the outer side of the drawer 120 and can electrically connect to the circuit structure 400 on the inner wall of the accommodating cavity 110 or to another contact member 300 on the drawer 120, thereby completing the closure of the entire light-emitting circuit.

[0146] The contact member 300 may also include a conductive member 330 disposed on the base 310. The contact member 320 is electrically connected to the light-emitting element 200 via the conductive member 330. The conductive member 330 also transmits current in the light-emitting circuit. By providing the conductive member 330 and connecting the contact member 320 and the light-emitting element 200, stable current transmission can be achieved.

[0147] The conductive member 330 may include a connecting piece 331. The conductive member 330 is connected to the positive electrode or the negative electrode of the light emitting element 200 via the connecting piece 331. The provision of the connecting piece 331 simplifies the structure of the conductive member 330 and facilitates assembly of the conductive member 330 with the base 310.

[0148] Reference Figure 12 The conductive member 330 may be provided with an elastic portion 332, which abuts against the connecting piece 331. When the elastic portion 332 abuts against the connecting piece 331, the elastic portion 332 is in a compressed state, and a rebound force is stored inside the elastic portion 332. Under the action of the rebound force, the elastic portion 332 always has a tendency to move toward the connecting piece 331, thereby maintaining a stable connection with the connecting piece 331.

[0149] For example, the conductive member 330 may be a metal sheet. By using the metal sheet as the conductive member 330, the conductive effect is better and the stability after installation is strong.

[0150] The connecting piece 331 may be a metal piece. The metal piece has a good conductive effect and can conduct current from the conductive member 330 to the light emitting element 200 without using a wire, thereby reducing the difficulty of arranging the wire.

[0151] In some other possible implementations, the conductive member 330 may be a wire. By using a wire as the conductive member 330 , the cost is low and the conductive member 330 can be flexibly arranged in the drawer 120 .

[0152] Reference Figure 10-11 In some possible implementations, the second contact portion 322 is disposed on a side wall of the drawer 120 . The second contact portion 322 extends toward the outside of the drawer 120 and can contact the circuit structure 400 .

[0153] The second contact portion 322 can move along the side wall close to or away from the drawer 120. When the second contact portion 322 moves with the drawer 120, it can automatically adjust its position to ensure reliable contact with the circuit structure 400 and reduce the possibility of poor contact.

[0154] When the drawer 120 is located in the accommodating cavity 110 , the contact member 300 is electrically connected to the circuit structure 400 via the second contact portion 322 , and the second contact portion 322 is in a compressed state.

[0155] It can be understood that when the drawer 120 is at least partially located outside the accommodating cavity 110, the second contact portion 322 is not in contact with the circuit structure 400. At this time, the second contact portion 322 is in a natural state, and the second contact portion 322 extends toward the outside of the drawer 120; when the drawer 120 is located inside the accommodating cavity 110, the second contact portion 322 corresponds to the position of the abutment portion 410 and is connected to the abutment portion 410. The abutment portion 410 will squeeze the second contact portion 322 to move the second contact portion 322 toward the drawer 120 to deform. At this time, the second contact portion 322 is in a compressed state, and a rebound force is stored inside the second contact portion 322. Under the action of the rebound force, the second contact portion 322 can maintain a tight connection with the abutment portion 410 to achieve a reliable connection between the second contact portion 322 and the circuit structure 400.

[0156] Exemplarily, the second contact portion 322 may be a metal spring. The metal spring has both electrical conductivity and resilience. When the second contact portion 322 abuts the abutting portion 410, it can achieve electrical connection between the contact member 300 and the circuit structure 400. Furthermore, the second contact portion 322 deforms after being connected to the abutting portion 410 to prevent the second contact portion 322 and the abutting portion 410 from disengaging, thereby achieving a stable connection between the contact member 300 and the circuit structure 400.

[0157] The first contact portion 321 can be extended or retracted in a direction approaching or moving away from the conductive member 330 . When the first contact portion 321 is electrically connected to the conductive member 330 , the first contact portion 321 is in a compressed state.

[0158] As will be understood, the first contact portion 321 is used to connect the conductive member 330 and the second connecting portion 323. The first contact portion 321 can expand and contract in a direction toward or away from the conductive member 330, thus providing elasticity. When the first contact portion 321 is electrically connected to the conductive member 330, it is compressed, and a rebound force is stored within the first contact portion 321. Under this rebound force, the first contact portion 321 tends to expand toward the conductive member 330 and rebound. This allows the first base portion to maintain contact with the conductive member 330, achieving a stable electrical connection.

[0159] For example, the first contact portion 321 can be a metal spring. The metal spring has both conductive properties and resilience. The second contact portion 322 is connected to the first contact portion 321 to enable current transmission. Furthermore, the first contact portion 321 is in a compressed state when electrically connected to the conductive member 330. This prevents separation or unstable contact between the first contact portion 321 and the conductive member 330, ensuring that current can be smoothly transmitted to the light-emitting element 200 through the circuit structure 400, the second contact portion 322, the first contact portion 321, and the conductive member 330.

[0160] Reference Figure 13 In some possible embodiments, the first end of the second contact portion 322 is connected to the first contact portion 321. The second contact portion 322 and the first contact portion 321 are connected as one body, which can ensure the transmission of current between the first contact portion 321 and the second contact portion 322, and ensure the continuity of the light-emitting circuit.

[0161] For example, the second contact portion 322 and the first contact portion 321 can be integrally formed. Integrally formed first and second contact portions 321, 322 can have good elasticity and be easily manufactured. For example, the first and second contact portions 321, 322 can be formed by cutting and bending a single piece of metal sheet, resulting in a simple manufacturing process.

[0162] The second contact portion 322 is located outside the drawer 120. When the drawer 120 is located in the accommodating cavity 110, the second contact portion 322 located outside the drawer 120 can correspond to the position of the abutment portion 410 and connect with the abutment portion 410 to achieve electrical connection between the contact member 300 and the circuit structure 400.

[0163] The second contact portion 322 is disposed on a side wall of the drawer 120. The position of the second contact portion 322 may correspond to the position of the abutment portion 410 of the circuit structure 400 within the accommodating cavity 110, so that when the drawer 120 is located within the accommodating cavity 110, the second contact portion 322 is correspondingly connected to the abutment portion 410.

[0164] As will be appreciated, the drawer 120 is movable along the front and rear sides of the housing 100, and the sidewalls of the drawer 120 are the two sides in the sliding direction of the drawer 120. The left and right sides of the drawer 120 correspond to the left and right sides of the housing 100. To correspond to the location of the second contact portion 322, the contact portions 410 of the circuit structure 400 can be disposed on the left and right sides of the housing 100 and located on the inner wall of the accommodating cavity 110.

[0165] In some possible embodiments, the second contact portion 322 is disposed on the side wall of the drawer 120 and close to the front side of the box body 100. When the drawer 120 is pulled out, the second contact portion 322 can be easily pulled out of the accommodating cavity 110, facilitating subsequent maintenance operations.

[0166] Reference Figure 13 The abutting member 320 may further include a connecting portion 323. The first end of the second contact portion 322 is connected to the first contact portion 321 via the connecting portion 323. The connecting portion 323 may be used to connect to the base 310 to improve the position stability of the abutting member 320 on the base 310.

[0167] Reference Figure 9 , a first end of the second contact portion 322 is close to the rear side of the drawer 120 , and a second end of the second contact portion 322 is close to the front side of the drawer 120 .

[0168] It is understood that the drawer 120 faces Figure 9 The side in the Y direction is the front side of the drawer 120; the drawer 120 faces away from Figure 9 The side in the middle Y direction is the rear side of the drawer 120. The first end of the second contact portion 322 and the second end of the second contact portion 322 are located at both ends of the extension direction of the second contact portion 322. The first end of the second contact portion 322 is connected to the first contact portion 321, and the first end of the second contact portion 322 and the first contact portion 321 can form a closed structure, which is close to the rear side of the drawer 120. The second end of the second contact portion 322 is a free end, and there is an opening between the second contact portion 322 and the drawer 120, which is close to the front side of the drawer 120.

[0169] When the drawer 120 is pulled toward the front of the housing 100, the first end of the second contact portion 322 gradually moves away from the first end of the second contact portion 322 on the adjacent drawer 120 until it is disconnected from the second contact portion 322 on the adjacent drawer 120. When the drawer 120 is pushed away from the front of the housing 100, the first end of the second contact portion 322 first contacts the second end of the second contact portion 322 on the adjacent drawer 120, and then gradually approaches the first end of the second contact portion 322 on the adjacent drawer 120 until the second contact portion 322 tightly abuts the second contact portion 322 on the adjacent drawer 120. This arrangement prevents the second ends of the second contact portions 322 on two adjacent drawers 120 from interlocking during relative movement, thereby affecting the smooth movement of the drawers 120.

[0170] Reference Figure 11-14 In some possible implementations, the base 310 is provided with a snap-fit block 311 . The drawer 120 is provided with a snap-fit groove 1211 .

[0171] The clamping block 311 can be inserted into the clamping groove 1211. The base 310 is connected to the drawer 120 by the form of the clamping block 311 and the clamping groove 1211. The connection structure is relatively simple and easy to assemble.

[0172] For example, a hook may be provided on the engaging block 311. A retaining groove may also be provided on the wall of the engaging slot 1211. When the engaging block 311 is inserted into the engaging slot 1211, the hook engages with the retaining groove, thereby improving the stability of the base 310 installed on the drawer 120 and preventing the base 310 from becoming loose.

[0173] The base 310 is provided with a receiving groove 312. The base 310 is provided with a mounting cover 340. The mounting cover 340 is disposed in the receiving groove 312.

[0174] The base 310 is provided with a receiving groove 312 to provide a mounting location for the mounting cover 340. Providing the mounting cover 340 on the base 310 is equivalent to providing a protective structure, ensuring that the abutment member 320 and the conductive member 330 can be safely installed in the base 310, preventing them from being damaged by the external environment, and improving the reliability of the circuit connection.

[0175] For example, a buckle 341 may be provided on the mounting cover 340. A slot 313 communicating with the receiving slot 312 may be provided on the base 310. The buckle 341 is engaged in the slot 313 to achieve a stable connection between the mounting cover 340 and the base 310.

[0176] The mounting cover 340 and the base 310 form a through-hole 350, which is used to at least pass through the through-hole 350 for the abutment member 320. The abutment member 320 is disposed within the through-hole 350, so that the first contact portion 321 of the abutment member 320 is located within the base 310 to electrically connect with the light-emitting element 200 via the conductive member 330; and the second contact portion 322 of the abutment member 320 is located outside the drawer 120, so that it can connect with the abutment portion 410 of the circuit structure 400 when the drawer 120 enters the accommodating cavity 110, and disengage from the abutment portion 410 of the circuit structure 400 when the drawer 120 is at least partially outside the accommodating cavity 110, thereby flexibly turning the light-emitting circuit on and off.

[0177] The base 310 is provided with a mounting portion 314. The conductive member 330 is connected to the mounting portion 314. The mounting portion 314 provides a mounting location for the conductive member 330, improving its stability. The light-emitting element 200 is mounted on the mounting portion 314. The mounting portion 314 also provides a mounting location for the light-emitting element 200. The light-emitting element 200 and the conductive member 330 are both mounted on the mounting portion 314, integrating them together to ensure a stable electrical connection.

[0178] The embodiment of the present application provides a refrigerator, including a housing 100, a drawer 120, and a light-emitting circuit; the housing 100 is provided with a receiving cavity 110, and the drawer 120 is movably disposed in the receiving cavity 110;

[0179] The light-emitting circuit includes a light-emitting element 200 and a contact 300; the light-emitting element 200 is disposed in the drawer 120, and the light-emitting element 200 is at least used to emit light toward the inner side of the drawer 120, and the contact 300 is at least used to control the on-off of the light-emitting circuit;

[0180] When the drawer 120 is in the pushed-in state, the contact 300 puts the lighting circuit in the on state, and the contact 300 is at least used to control the lighting element 200 to emit light; when the drawer 120 is in the pulled-out state, the contact 300 puts the lighting circuit in the off state, and the light-emitting element 200 does not emit light.

[0181] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
