DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments (or, the implementation manners) of the present application will be clearly and completely described in combination with the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings represent the same or similar elements unless otherwise indicated.

[0047] If the application embodiments involve directional indications or positional relationships (such as up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings); if the specific posture changes, the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. in the application embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0048] With the development of social economy and the improvement of people's living standards, the refrigerator gradually becomes an indispensable household appliance in people's daily life. With the continuous expansion of intelligent technology to the field of household appliances, consumers' pursuit of ease of use and intelligence in the use experience of household appliances is getting higher and higher. The automatic opening and closing function of the drawer of the refrigerator is also more and more widely used in the refrigerator.

[0049] In the related art, a driving device is usually used to realize automatic opening or closing of the drawer of the refrigerator, but since the driving device is arranged to realize automatic opening and closing of the drawer, it will affect manual opening and closing of the drawer, which is not conducive to the use experience of users.

[0050] Therefore, a cabinet device is provided, which can realize automatic opening or closing of the drawer and improve the reliability of manual opening and closing of the drawer, thereby improving the use experience of users.

[0051] In order to better understand the cabinet device of the present application, the refrigerator applying the cabinet device is described.

[0052] As shown in Figure 1 some embodiments, the refrigerator 1 comprises a cabinet door 10 and a cabinet device 20, the cabinet device 20 comprising a cabinet 210 provided with a storage cavity 211, and the cabinet door 10 is movably connected with the cabinet 210 to open or close the storage cavity 211.

[0053] As shown in Figures 1 to 4 some embodiments, the cabinet device 20 further comprises a drawer 220 and a transmission device 230. The drawer 220 is telescopically arranged in the storage cavity 211. The transmission device 230 comprises a carrier 231, a clutch 232, a telescopic assembly 233 and a motor 234. The carrier 231 is fixed to the cabinet 210. The clutch 232 has a transmission state and a separation state. The telescopic assembly 233 comprises a rotating member 2331 rotatably arranged on the carrier 231 and a telescopic member 2332 cooperating with the rotating member 2331. The telescopic member 2332 is in transmission connection with the drawer 220. The motor 234 is in transmission connection with the rotating member 2331 through the clutch 232. When the clutch 232 is in the transmission state, the motor 234 drives the rotating member 2331 to rotate through the clutch 232, so as to drive the drawer 220 to move relative to the cabinet 210 through the telescopic member 2332. When the clutch 232 is in the separation state, the motor 234 is disconnected from the telescopic assembly 233.

[0054] Thus, when the user automatically opens or closes the drawer 220, the clutch 232 is in a transmission state, and the motor 234 drives the rotating member 2331 to rotate through the clutch 232. The rotating member 2331 cooperates with the telescopic member 2332, so that the rotating member 2331 drives the telescopic member 2332 to move. The telescopic member 2332 is in transmission connection with the drawer 220, so that the telescopic member 2332 drives the drawer 220 to move relative to the cabinet 210, thereby automatically opening or closing the drawer 220. When the user chooses to manually open or close the refrigerator 1, the clutch 232 is in a disengaged state, and the motor 234 is disconnected from the telescopic assembly 233, allowing the user to easily manually open or close the drawer 220. The cabinet device 20 can automatically open or close the drawer 220 and improve the reliability of the user's manual opening or closing of the drawer 220, which is conducive to improving the user experience.

[0055] It should be noted that, in addition to the motor 234 , the specific implementation method of the power source for driving the rotating member 2331 may also include other methods, such as hydraulic drive and cylinder drive, etc.

[0056] It should be noted that there are many specific implementations of the transmission connection between the telescopic member 2332 and the drawer 220, including fixed connection between the telescopic member 2332 and the drawer 220 to achieve transmission, and transmission connection between the telescopic member 2332 and the drawer 220 through a transmission mechanism.

[0057] like Figure 1 As shown, in some embodiments, the refrigerator 1 further includes a control device 30, which is in communication with the transmission device 230 and can control the transmission device 230 to drive the drawer 220 to automatically open or close the drawer 220. In this way, the control device 30 controls the transmission device 230 to open or close the drawer 220, thereby improving the intelligence of the refrigerator 1 and enhancing the user experience.

[0058] like Figures 5 to 7As shown, in some embodiments, the clutch 232 includes an active member 2321 transmission-connected to the output end 2341 of the motor 234, a driven member 2322 transmission-connected to the rotating member 2331, and a clutch member 2323 disposed between the active member 2321 and the driven member 2322. The driven member 2322 includes an output portion 201 transmission-connected to the rotating member 2331 and a mating portion 202 fixedly connected to the output portion 201. The active member 2321 is transmission-connected to the clutch member 2323 to drive the clutch member 2323 to move relative to the mating portion 202. When the clutch 232 is in a transmission state, the clutch member 2323 transmission-mates with the mating portion 202. When the clutch 232 is in a disengaged state, the clutch member 2323 is separated from the mating portion 202. Thus, when a user automatically opens or closes the drawer 220, the clutch 232 is in a transmission state, the clutch member 2323 is in transmission engagement with the mating portion 202, and the output end 2341 of the motor 234 is in transmission connection with the active member 2321 of the clutch 232, thereby driving the active member 2321 to rotate. The active member 2321 is in transmission connection with the clutch member 2323, causing the active member 2321 to drive the clutch member 2323. When the clutch 232 is in a transmission state, the clutch member 2323 is in transmission engagement with the mating portion 202, thereby driving the mating portion 202. The mating portion 202 then drives the output portion 201 of the driven member 2322, thereby driving the rotating member 2331 to rotate. The rotating member 2331 is in transmission connection with the telescopic member 2332, causing the telescopic member 2332 to drive the drawer 220 to move, thereby achieving automatic opening or closing of the drawer 220. When the user chooses to manually open or close the refrigerator 1, the clutch 232 is in a disengaged state, and the clutch member 2323 is separated from the matching portion 202. The active member 2321 is disconnected from the driven member 2322, and the user can easily manually open or close the drawer 220.

[0059] like Figures 6 to 8As shown, in some embodiments, the mating portion 202 includes a receiving groove 2021 and a connecting portion 2022 disposed on a sidewall of the receiving groove 2021. The clutch 232 further includes a transmission assembly, which includes a transmission member 2324 fixedly connected to the active member 2321, a clutch member 2323 in transmission engagement with the transmission member 2324, and a rotating member 2325 rotatably disposed within the receiving groove 2021. The rotating member 2325 includes a guide portion 2326. The clutch member 2323 slidably engages with the guide portion 2326 and has a transmission state in which it is in transmission engagement with the connecting portion 2022 and a separation state in which it is separated from the connecting portion 2022. The clutch member 2323 can be reset to a separation state. The transmission member 2324 can rotate relative to the rotation member 2325 and can rotate with the active member 2321 to push the clutch member 2323 from the separation state to the transmission state. When the clutch 2323 is in the transmission state, the active member 2321 can drive the transmission assembly and the driven member 2322 to rotate. When the clutch 2323 is in the separation state, the driven member 2322 can rotate relative to the transmission assembly and the active member 2321.

[0060] It should be noted that the active member 2321 is used to connect to the output shaft of the motor 234, and the driven member 2322 is used to connect to an active component that can be driven by the motor 234 or manually by the user. For example, when the drawer 220 of the refrigerator 1 needs to be driven to open and close automatically, the active component can be the drawer 220 component of the refrigerator 1. The active component can be any part that the user desires to open and close automatically or manually. The user can select the appropriate active component based on actual usage needs, and this disclosure does not limit this.

[0061] The transmission assembly is intermittently connected between the active member 2321 and the passive member 2322. When the transmission assembly securely connects the active member 2321 and the passive member 2322, the motor 234 drives the active member 2321 and the passive member 2322 to rotate synchronously, thereby automatically opening and closing the movable assembly. When the transmission assembly separates the active member 2321 and the passive member 2322, the passive member 2322 is no longer controlled by the rotation of the motor 234, allowing the user to manually open and close the movable assembly.

[0062] See also Figure 9 as well as Figure 10 In some embodiments, to facilitate the movement of the clutch member 2323 by the transmission member 2324, the transmission member 2324 includes a mounting portion 2327 connected to the active member 2321 and a transmission portion 2328 connected to the mounting portion 2327. The transmission portion 2328 includes a protrusion 2328a connected to the mounting portion 2327 and a recess 2328b adjacent to the protrusion 2328a. When the clutch member 2323 is pressed against the protrusion 2328a, the clutch member 2323 is in a transmission state. When the clutch member 2323 is partially inserted into the recess 2328b, the clutch member 2323 is in a disengaged state.

[0063] It should be noted that the mounting portion 2327 may be provided with a socket, and the active member 2321 may be plugged and fixed to the mounting portion 2327 through the socket. The socket may be configured as a non-circular hole, and the end of the active member 2321 inserted into the socket may be configured as a shape that matches the socket to prevent relative rotation between the active member 2321 and the mounting portion 2327. In some embodiments, the socket may also be configured as a circular hole, and after the active member 2321 is inserted into the circular hole, it may be secured with an interference fit, adhesive bonding, or welding to prevent relative rotation between the active member 2321 and the mounting portion 2327, which is not limited in this disclosure. In some embodiments, the active member 2321 may also be integrally formed with the mounting portion 2327.

[0064] The transmission portion 2328 is configured to engage with the clutch member 2323. The protrusion 2328a is configured to push the clutch member 2323 into engagement with the slot in the sidewall of the receiving slot 2021, placing the clutch member 2323 in a transmission state. The recess 2328b is configured to allow the clutch member 2323 to disengage from the slot in the sidewall of the receiving slot 2021, placing the clutch member 2323 in a disengaged state. To enable the motor 234 to drive the transmission member 2324 against the clutch member 2323 to the transmission state in both forward and reverse rotation modes, the transmission portion 2328 may be provided with two protrusions 2328a, spaced apart on either side of the recess 2328b.

[0065] like Figure 4 As shown, in some embodiments, the telescopic assembly 233 further includes a drive rod 2333 connected to the telescopic member 2332, the carrier 231 is provided with a connection notch 2311, and the drive rod 2333 passes through the connection notch 2311 and is connected to the drawer 220 to drive the drawer 220 to move telescopically relative to the housing 210. In this way, when the user automatically opens or closes the drawer 220 of the refrigerator 1, the motor 234 is connected to the rotating member 2331 through the clutch 232, and the rotating member 2331 drives the telescopic member 2332 to move telescopically. The drive rod 2333 is connected to the telescopic member 2332, so that the telescopic member 2332 drives the drive rod 2333 to move, and the drive rod 2333 passes through the connection notch 2311 and is connected to the drawer 220, so that the drive rod 2333 can drive the drawer 220 to move relative to the housing 210, thereby achieving automatic opening or closing of the drawer 220.

[0066] like Figure 1As shown, in some embodiments, the driving rod 2333 further includes a driving end 203 connected to the telescopic member 2332, a connecting end 204 connected to the drawer 220, and a rod body 205 disposed between the driving end 203 and the connecting end 204. The rod body 205 is provided with a first avoidance groove 206 to avoid the rotating member 2331. In this way, when the user automatically opens or closes the drawer 220, the telescopic member 2332 telescopes along the rotating member 2331, and the driving rod 2333 is connected to the telescopic member 2332, so that the driving rod 2333 moves under the action of the telescopic member 2332 to open or close the drawer 220. By setting a first avoidance groove 206 on the rod body 205, when the drawer 220 is automatically opened or closed, the driving rod 2333 can avoid the rotating part 2331 through the first avoidance groove 206, avoiding motion interference between the driving rod 2333 and the rotating part 2331 during movement, thereby improving the reliability of automatic opening and closing of the drawer 220.

[0067] like Figure 11 As shown, in some embodiments, the rotating member 2331 includes a screw rod 2334, and the telescopic member 2332 includes a nut 2335 that is threadably engaged with the screw rod 2334. The output end 2341 of the motor 234 is fixedly connected to the screw rod 2334 via the clutch 232, and the screw rod 2334 can be driven to rotate by the motor 234. The nut 2335 is slidably connected to the carrier 231. In this way, when the user automatically opens or closes the drawer 220 of the refrigerator 1, the clutch 232 is in a transmission state, and the output end 2341 of the motor 234 is fixedly connected to the screw rod 2334 through the clutch 232, so that the output end 2341 drives the screw rod 2334 to rotate, and the telescopic member 2332 includes a nut 2335 that can be threadedly engaged with the screw rod 2334, and the nut 2335 and the supporting member 231 are slidingly connected, so that the telescopic member 2332 can drive the driving rod 2333 to move, thereby driving the drawer 220 to move relative to the box body 210, thereby realizing automatic opening or closing of the drawer 220.

[0068] like Figure 12As shown, in other embodiments, the rotating member 2331 includes a driving gear 2336, the telescopic member 2332 includes a driven rack 2337 meshing with the driving gear 2336, the driving gear 2336 is fixedly connected to the output end 2341, and the driving gear 2336 can be driven to rotate by the output end 2341, and the driven rack 2337 is fixedly connected to the telescopic member 2332, and the driving gear 2336 meshes and cooperates with the driven rack 2337. In this way, when the user automatically opens or closes the drawer 220, the motor 234 is in operation, the clutch 232 is in a transmission state, the output end 2341 of the motor 234 drives the driving gear 2336 to rotate through the clutch 232, and the driven rack 2337 meshes and cooperates with the driving gear 2336, thereby driving the driven gear to reciprocate along the carrier 231. The driven rack 2337 is fixedly connected to the telescopic member 2332, driving the driving rod 2333 to move, thereby driving the drawer 220 to move relative to the box body 210, thereby realizing automatic opening or closing of the drawer 220.

[0069] like Figure 13 as well as Figure 14 As shown, in some embodiments, the box body 210 includes a bearing surface 212 disposed in the storage cavity 211, the transmission device 230 is disposed between the drawer 220 and the bearing surface 212, and the drawer 220 is provided with a second avoidance groove 221 to avoid the transmission device 230. In this way, by arranging the transmission device 230 between the drawer 220 and the bearing surface 212, the drawer 220 can move relative to the box body 210 under the action of the transmission device 230 to open or close the drawer 220. Since the transmission device 230 is disposed between the drawer 220 and the bearing surface 212, in order to avoid motion interference between the drawer 220 and the transmission device 230, a second avoidance groove 221 is provided in the drawer 220 to avoid the transmission device 230, thereby avoiding motion interference when opening or closing the drawer 220. By providing the second avoidance groove 221 , the transmission device 230 is located in the second avoidance groove 221 , so that the drawer 220 and the bearing surface 212 can be more closely matched, making the overall structure of the box device 20 more compact.

[0070] In an embodiment of the present application, the box device 20 can be applied to the refrigerator 1. In some embodiments, the box 210 further includes an inner liner 213, which is disposed in the storage cavity 211. The drawer 220 is slidably connected to the inner liner 213. In this way, the inner liner 213 of the refrigerator 1 can be used as a freezer or a refrigerator for storing food. By slidingly connecting the drawer 220 to the inner liner 213, the drawer 220 is disposed in the inner liner 213, so that the drawer 220 can be used to store food.

[0071] like Figure 2As shown, in some embodiments, the box device 20 further includes a slide rail assembly 240, and the drawer 220 is slidably connected to the box body 210 via the slide rail assembly 240. In this way, when the user automatically opens or closes the drawer 220, the transmission device 230 is used to drive the drawer 220, and the drawer 220 is slidably connected to the box body 210 via the slide rail assembly 240, so that the drawer 220 can slide relative to the box body 210 via the slide rail assembly 240 under the action of the transmission device 230 to open or close the drawer 220. In addition, when the user manually opens or closes the drawer 220, the drawer 220 is slidably connected to the box body 210 via the slide rail assembly 240, making it easier for the user to open or close the drawer 220, which is conducive to improving the user experience.

[0072] like Figure 3 、 Figure 13 as well as Figure 14 As shown, in some embodiments, the storage cavity 211 is provided with an opening 207, and the slide rail assembly 240 includes a guide rail 241 and a slide rail 242 capable of cooperating with the guide rail 241. The guide rail 241 is fixedly disposed within the storage cavity 211, and the slide rail 242 is mounted on the drawer 220. When the clutch 232 is in the transmission state, the motor 234 drives the drawer 220 to move along the length of the guide rail 241 via the telescopic member 2332, so that at least a portion of the drawer 220 can extend out of the opening 207. In this way, when the drawer 220 is automatically opened or closed, the clutch 232 is in the transmission state, and the motor 234 is fixedly connected to the rotating member 2331 via the clutch 232, driving the rotating member 2331 to rotate, and under the action of the telescopic member 2332, the drawer 220 can be driven to open or close. During the process of opening the drawer 220, the guide rail 241 and the slide rail 242 cooperate, so that the drawer 220 can move along the length direction of the guide rail 241 under the drive of the motor 234, so that at least a portion of the drawer 220 can extend out of the opening 207 to open the drawer 220. The cooperation between the guide rail 241 and the slide rail 242 allows the drawer 220 to be extended further, making it more convenient for the user to take items in and out of the drawer 220.

[0073] It should be noted that the length direction of the guide rail 241 is Figure 4 The X direction is shown.

[0074] like Figure 11As shown, in some embodiments, the telescopic member 2332 comprises a starting position 208 and an ending position 209 which is spaced apart from the starting position 208 along the moving direction of the telescopic member 2332. When the telescopic member 2332 is at the starting position 208, the drawer 220 is in the retracted state. When the telescopic member 2332 is at the ending position 209, the drawer 220 is in the extended state. The transmission device 230 further comprises a first position detecting assembly 235 and a second position detecting assembly 236. The first position detecting assembly 235 and the second position detecting assembly 236 are arranged on the carrier 231. The first position detecting assembly 235 is used to detect whether the telescopic member 2332 is at the starting position 208, and the second position detecting assembly 236 is used to detect whether the telescopic member 2332 is at the ending position 209. Thus, when the telescopic member 2332 is at the starting position 208, the drawer 220 is in the retracted state, i.e. the drawer 220 is closed. When the telescopic member 2332 is at the ending position 209, the drawer 220 is in the extended state, i.e. the drawer 220 is opened and the opening amplitude is maximum. Therefore, by arranging the first position detecting assembly 235 and the second position detecting assembly 236 on the carrier 231, the state of the drawer 220 can be determined by detecting whether the telescopic member 2332 is at the starting position 208 or at the ending position 209.

[0075] It can be understood that, when the drawer 220 is closed or the opening amplitude is maximum, the first position detecting assembly 235 and the second position detecting assembly 236 can control the transmission device 230 to stop working, so as to avoid the transmission assembly still working when the drawer 220 is closed or the opening amplitude is maximum, which can cause damage to the refrigerator 1.

[0076] It should be noted that the moving direction of the telescopic member 2332 is the X direction as shown. Figure 8

[0077] It should be noted that, Figure 2 As shown, the drawer 220 is in the retracted state, Figure 3 As shown, the drawer 220 is in the extended state.

[0078] As shown in FIG. 1, the refrigerator 1 comprises a cabinet 10, a refrigerator compartment 11 and a freezer compartment 12. The refrigerator compartment 11 and the freezer compartment 12 are arranged in the cabinet 10. The refrigerator compartment 11 and the freezer compartment 12 are separated by a partition 13. The refrigerator compartment 11 and the freezer compartment 12 are arranged in the cabinet 10 in a vertical direction. The refrigerator compartment 11 is arranged above the freezer compartment 12. Figure 15 and Figure 16 ​As shown, in some embodiments, the first position detection assembly 235 and the second position detection assembly 236 each include a transmitting end 237 and a receiving end 239 spaced apart from the transmitting end 237 to form a fitting gap 238, and the telescopic member 2332 is provided with a protrusion 2338. When the telescopic member 2332 is in the starting position 208 or the ending position 209, the protrusion 2338 is inserted into the fitting gap 238 to separate the transmitting end 237 from the receiving end 239. When the telescopic member 2332 is in the non-starting position 208 or the ending position 209, the protrusion 2338 leaves the fitting gap 238. In this way, the protrusion 2338 is inserted into the fitting gap 238 to separate the transmitting end 237 and the receiving end 239, thereby determining whether the telescopic member 2332 is in the starting position 208 or the ending position 209. In this way, when the protrusion 2338 is inserted into the fitting gap 238, the protrusion 2338 and the fitting gap 238 can be kept away from each other, reducing friction and thus improving the overall life.

[0079] It should be noted that there are many specific implementation methods for the first position detection component 235 and the second position detection component 236, including pressure sensors, magnetic sensors, photoelectric sensors, infrared sensors, etc.

[0080] It should be noted that the first position detection assembly 235 and the second position detection assembly 236 can be assembled into a module and then modularly assembled into the transmission device 230. Alternatively, they can be separately assembled into the carrier 231 and then assembled into a module with the carrier 231. This facilitates the modular assembly of the transmission device 230 and improves assembly efficiency.

[0081] like Figure 17 as well as Figure 19 As shown, in some embodiments, the refrigerator 1 further includes a compressor 40, a condenser 50, an evaporator 60, and a throttling assembly 70. The housing 210 further includes a freezing chamber 214 and a refrigerating chamber 215. The compressor 40, the condenser 50, the evaporator 60, and the throttling assembly 70 are respectively disposed in the housing 210, and at least a portion of the evaporator 60 is disposed in the freezing chamber 214.

[0082] Combine Figure 19As shown, when the refrigerator 1 is in operation, the compressor 40 outputs high-temperature, high-pressure gaseous refrigerant to the condenser 50, where it is condensed into medium-temperature, high-pressure refrigerant. The medium-temperature, high-pressure refrigerant undergoes expansion and throttling by the throttling assembly 70, further reducing its pressure and temperature. It then flows out of the throttling assembly 70 as a low-temperature, low-pressure liquid refrigerant to the evaporator 60. The low-temperature, low-pressure liquid refrigerant evaporates into a gaseous refrigerant within the evaporator 60. At least a portion of the evaporator 60 is located within the freezer compartment 214, allowing the refrigerant to absorb a significant amount of heat from the freezer compartment 214 during evaporation, thereby lowering the temperature within the freezer compartment 214 and facilitating the use of the freezer compartment 214 to freeze items, thereby achieving refrigeration in the refrigerator 1. The refrigerant exiting the evaporator 60 is then replenished back into the compressor 40, forming a refrigerant circuit. In this manner, the refrigerant continuously circulates within the refrigerant circuit to maintain a refrigerated environment (e.g., below -1°C) within the freezer compartment 214.

[0083] In some embodiments, an air duct 216 is provided between the refrigeration compartment 215 and the freezer compartment 214 to facilitate the transportation of part of the cold air from the freezer compartment 214 to the refrigeration compartment 215 through the air duct 216 to reduce or maintain the low temperature environment of the refrigeration compartment 215 (for example, 2°C to 8°C).

[0084] In some embodiments, the freezer compartment 214 is positioned below the refrigerator compartment 215 along the height of the refrigerator 1. The refrigerator 1 further includes a first fan (not labeled) disposed within the housing 210. The first fan's air inlet or outlet is connected to the air duct 216, which is used to transport some of the cold air from the freezer compartment 214 to the refrigerator compartment 215.

[0085] like Figure 18 As shown, the height direction of the refrigerator 1 is the Z-axis direction.

[0086] The drawer 220 is disposed in the refrigerator compartment 215 and / or the freezer compartment 214 .
