[0003] A refrigerator is a household appliance that lowers its internal temperature to provide a low-temperature storage chamber for food or ingredients, thereby extending the shelf life of the food or ingredients. A refrigerator generally consists of three parts: a cabinet, a refrigeration system, and a control system. During the flow of refrigerant, heat is exchanged between the refrigerator's storage chamber and the external environment through evaporation and condensation, thereby ensuring that the storage chamber remains at a low temperature. As the types of items stored in refrigerators become more diverse, users' demands for refrigerators are also increasing. For example, if a user needs to store a variety of different items, the storage humidity required for each item may also vary.

[0004] Therefore, current refrigerators are generally provided with mutually independent wet and dry areas in the cabinet to meet the needs of users for storing different items.

[0005] In the process of implementing the embodiments of this application, it was found that there are at least the following problems in the related art:

[0006] Existing refrigerators typically have multiple independent drawers within the refrigerator body, creating separate wet and dry areas by adjusting the humidity within the drawers. This prevents users from adjusting the size of the wet and dry areas, reducing the user experience.

[0072] As shown in FIG. 1 to FIG. 20 , the embodiments of the present disclosure provide a drawer assembly and a refrigeration device, and the user can adjust the size of the dry area 13 and the wet area 14 by himself, thereby improving the user experience.

[0073] Example 1

[0074] As shown in FIG. 1 to FIG. 12 , an embodiment of the present disclosure provides a drawer assembly, including a drawer body 10 , a partition assembly 20 , a telescopic plate 21 , and a drive assembly.

[0075] The drawer body 10 is provided with a dry area 13 and a wet area 14 .

[0076] The partition assembly 20 is slidably disposed in the drawer body 10 to separate the dry area 13 from the wet area 14 , and an installation interlayer is disposed in the partition assembly 20 .

[0077] The telescopic plate 21 is slidably disposed in the mounting interlayer of the partition assembly 20 and is disposed corresponding to the side wall surface of the drawer body 10. The telescopic plate 21 can slide in a first direction and abut against the side wall surface of the drawer body 10 or slide in a second direction and detach from the side wall surface of the drawer body 10.

[0078] Specifically, the telescopic plate 21 is installed in the installation interlayer, and can slide in the installation interlayer in a first direction to a first position or in a second direction to a second position.

[0079] The driving assembly is arranged in the installation interlayer of the partition assembly 20 and is transmission-connected to the telescopic plate 21; wherein, the driving assembly can drive the telescopic plate 21 to slide along a preset track in the installation interlayer, so that the telescopic plate 21 extends out of the installation interlayer and abuts against the side wall surface of the drawer body 10, or, the telescopic plate 21 is retracted into the installation interlayer and detached from the side wall surface of the drawer body 10.

[0080] Specifically, the drawer body 10 is provided with a storage area. A partition assembly 20 is disposed within the storage area to separate the storage area into a dry area 13 and a wet area 14, as shown in Figure 2 . The drawer assembly can be used in refrigeration equipment, which can independently adjust the humidity within the dry and wet areas 13 and 14. Users can store items requiring low humidity in the dry area 13 and items requiring high humidity in the wet area 14. A retractable plate 21 is slidably disposed within the mounting interlayer and positioned corresponding to the sidewalls of the storage area. A drive assembly is mounted within the mounting interlayer and is in transmission connection with the retractable plate 21, as shown in Figure 5 . The user uses the drive assembly to retract the retractable plate 21 into the mounting interlayer and disengage it from the sidewalls of the drawer body 10. The partition assembly 20 can then be slid within the drawer body 10 to adjust the volume of the dry and wet areas 13 and 14. Once the adjustment is complete, the drive assembly can be used to extend the retractable plate 21 out of the mounting interlayer and into contact with the sidewalls of the drawer body 10, preventing the partition assembly 20 from sliding. If a large number of items need to be stored at low humidity, the user can slide the partition assembly 20 toward the wet area 14 to increase the volume of the dry area 13; if a large number of items need to be stored at high humidity, the user can slide the partition assembly 20 toward the dry area 13 to increase the volume of the wet area 14. This arrangement allows the user to adjust the size of the dry area 13 and the wet area 14, improving the user experience.

[0081] It can be understood that if the user only needs to store items with low humidity, the user can slide the partition assembly 20 in the direction of the wet area 14 to the corresponding side wall surface, and the storage area is now completely the dry area 13. Similarly, if the user only needs to store items with high humidity, the user can slide the partition assembly 20 in the direction of the dry area 13 to the corresponding side wall surface, and the storage area is now completely the wet area 14.

[0082] As shown in Figures 1 and 2, the drawer body 10 is optionally provided with an opening, and a cover plate 11 is provided at the opening, and the cover plate 11 is detachably mounted on the opening of the drawer body 10. When the cover plate 11 is buckled into the opening, the dry area 13 and the wet area 14 are in a completely closed state.

[0083] As shown in FIG. 4 and FIG. 5 , optionally, the partition assembly 20 includes a first partition 203 and a second partition 204 clamped to the first partition 203 , and a gap is provided between the first partition 203 and the second partition 204 to form an installation interlayer.

[0084] As shown in Figures 17 and 18 , first partition plate 203 is provided with a snap-fitting groove 2031, and second partition plate 204 is provided with a snap-fitting protrusion 2041 corresponding to snap-fitting groove 2031. The snap-fitting protrusion 2041 snaps into the snap-fitting groove 2031, thereby snapping the second partition plate 204 to the first partition plate 203. When the second partition plate 204 is snap-fitted to the first partition plate 203, a gap remains between the second partition plate 204 and the first partition plate 203, forming a mounting interlayer.

[0085] In actual application, the storage area of ​​the drawer body 10 is provided with a first side wall surface and a second side wall surface, and the first side wall surface and the second side wall surface are relatively arranged on both sides of the partition assembly 20, and accordingly, the first side wall surface and the second side wall surface are relatively arranged on both sides of the telescopic plate 21.

[0086] When the telescopic plate 21 is in the first position, the telescopic plate 21 extends out of the mounting interlayer and abuts against the first side wall surface of the storage area. Specifically, the edge of the telescopic plate 21 extends out of the mounting interlayer and abuts against the first side wall surface of the storage area. At this time, the edge of the partition assembly 20 corresponding to the second side wall surface also abuts against the second side wall surface to prevent the partition assembly 20 from sliding.

[0087] When the telescopic plate 21 is located at the second position, the edge of the telescopic plate 21 is retracted into the mounting interlayer to be separated from the first side wall.

[0088] In actual application, the width of the partition assembly 20 is smaller than the width of the storage area to avoid the edges on both sides of the partition assembly 20 abutting against the first side wall surface and the second side wall surface at the same time when the telescopic plate 21 is in the second position.

[0089] As shown in Figure 18 , the telescopic plate 21 is optionally provided with an escape opening 211, and the engaging protrusion 2041 and the engaging groove 2031 are disposed at positions corresponding to the escape opening 211. The engaging protrusion 2041 can pass through the escape opening 211 and engage with the engaging groove 2041. This arrangement allows the engaging protrusion 2041 to position the telescopic plate 21, preventing it from shaking. Furthermore, the engaging protrusion 2041 can also limit the position of the telescopic plate 21, preventing it from slipping out of the mounting interlayer.

[0090] As shown in Figures 5 to 8, in some embodiments, the drive assembly includes a drive rack 31, a telescopic rack 32, and a gear 33. The drive rack 31 is disposed within the mounting interlayer; the telescopic rack 32 is disposed horizontally within the mounting interlayer and is connected to the telescopic plate 21; and the gear 33 is meshedly connected to the drive rack 31 and the telescopic rack 32, respectively. The drive rack 31 can move in a first direction and, via the gear 33, drive the telescopic rack 32 and the telescopic plate 21 out of the mounting interlayer, or the drive rack 31 can move in a second direction and, via the gear 33, drive the telescopic rack 32 and the telescopic plate 21 back into the mounting interlayer.

[0091] Specifically, the drive rack 31 is vertically mounted within the mounting interlayer, and a first tooth portion 312 is provided on the edge of the drive rack 31 facing the telescopic plate 21. The telescopic rack 32 is horizontally mounted within the mounting interlayer, located on the side of the drive rack 31 adjacent to the telescopic plate 21, and a second tooth portion 321 is provided on the edge of the telescopic rack 32 corresponding to the first tooth portion 312. A gear 33 is rotatably mounted within the mounting interlayer, and the gear 33 is meshed with the first tooth portion 312 and the second tooth portion 321, respectively. The drive rack 31 can move vertically downward to drive the telescopic rack 32 outward, thereby driving the telescopic plate 21 to extend out of the mounting interlayer and abut against the side wall of the drawer body 10. The drive rack 31 can also move vertically upward to drive the telescopic rack 32 inward, thereby driving the telescopic plate 21 to retract into the mounting interlayer and disengage from the side wall of the drawer body 10.

[0092] As shown in Figure 7, in some embodiments, the driving rack 31 is provided with a pushing portion 34; as shown in Figure 4, the side wall surface of the partition assembly 20 and the pushing portion 34 are provided with an avoidance opening 201 corresponding to the avoidance opening 201; wherein, the pushing portion 34 can extend to the outside of the partition assembly 20 through the avoidance opening 201, and the driving rack 31 can be pushed to move in the first direction or the second direction through the pushing portion 34.

[0093] Specifically, the sidewall of the drive rack 31 facing the first partition 203 and / or the second partition 204 is provided with a push protrusion to form a push portion 34. The first partition 203 and / or the second partition 204 are provided with a clearance opening 201 at a position corresponding to the push protrusion. The push protrusion can extend through the clearance opening 201 to the other side of the first partition 203 and / or the second partition 204. In this way, a user can use the push protrusion to push the drive rack 31 in the first or second direction.

[0094] As shown in Figure 5, in some embodiments, the drive assembly further includes a first elastic element 22. The first elastic element 22 is disposed within the mounting interlayer, with its two ends connected to the drive rack 31 and the partition assembly 20, respectively; wherein the first elastic element 22 can push the drive rack 31 to move in the first direction.

[0095] Specifically, a mounting slot 313 is provided through the drive rack 31. A fixing seat is provided at a position corresponding to the mounting slot 313 on the partition assembly 20, and the fixing seat extends into the mounting slot 313, as shown in Figures 5 and 7. One end of the first elastic element 22 is connected to the fixing seat, and the other end is connected to the lower edge of the mounting slot 313. In this way, the first elastic element 22 can push the drive rack 31 downward.

[0096] In some embodiments, the driving rack 31 is provided with a guide portion; the partition assembly 20 is also provided with a guide matching portion corresponding to the guide portion; wherein the guide matching portion can guide the guide portion so that the driving rack 31 moves along the first direction or the second direction.

A guide protrusion 202 is provided at a position corresponding to the first guide groove 311 on the partition assembly 20 to form a guide mating portion. The guide protrusion 202 is inserted into the first guide groove 311, as shown in Figure 6. During the movement of the drive rack 31, the guide protrusion 202 can limit the first guide groove 311, so that the drive rack 31 moves in the first direction or the second direction.

[0098] As shown in Figure 5 , the drive rack 31 is optionally provided with two first guide grooves 311, and the two first guide grooves 311 are distributed vertically. The partition assembly 20 is provided with two guide protrusions 202 corresponding to the two first guide grooves 311, and the two guide protrusions 202 are respectively inserted into the two first guide grooves 311. In this way, the two guide protrusions 202 can respectively limit the two first guide grooves 311 to prevent the drive rack 31 from rotating.

[0099] As shown in FIG. 5 and FIG. 8 , in some embodiments, the partition assembly 20 is further provided with a guide bracket 26 corresponding to the telescopic rack 32 , and the telescopic rack 32 is mounted on the guide bracket 26 ; wherein the telescopic rack 32 can slide horizontally along the guide bracket 26 .

[0100] Specifically, a guide bracket 26 is provided within the mounting interlayer of the partition assembly 20 at a position corresponding to the telescopic rack 32. The guide bracket 26 is provided with a second horizontal guide groove. The telescopic rack 32 slides within the second guide groove, which supports and guides the telescopic rack 32, allowing it to move horizontally.

[0101] As shown in FIG5 , in some embodiments, the drawer assembly is provided with two groups of telescopic plates 21 , and the two groups of telescopic plates 21 are relatively arranged on both sides of the partition assembly 20 ; wherein the driving assembly is respectively connected to the two groups of telescopic plates 21 in transmission.

[0102] Specifically, the two sets of telescopic plates 21 are respectively a first telescopic plate and a second telescopic plate. The drawer assembly includes a first telescopic plate positioned corresponding to the first side wall and a second telescopic plate positioned corresponding to the second side wall. A drive assembly is respectively in transmission connection with the first and second telescopic plates to drive the first and second telescopic plates to extend or retract into the mounting interlayer. When the first telescopic plate extends from the mounting interlayer, it abuts the first side wall. When the second telescopic plate extends from the mounting interlayer, it abuts the second side wall.

[0103] As shown in Figure 5, in some embodiments, the telescopic rack 32 includes a first telescopic rack and a second telescopic rack, and the first telescopic rack and the second telescopic rack are respectively connected to the two groups of telescopic plates 21; the gear 33 includes a first gear and a second gear respectively arranged corresponding to the first telescopic rack and the second telescopic rack; wherein the first gear is respectively meshed and connected to the first telescopic rack and the driving rack 31, and the second gear is respectively meshed and connected to the second telescopic rack and the driving rack 31.

[0104] Specifically, the first telescopic rack is disposed on the side of the drive rack 31 facing the first telescopic plate, and the first telescopic rack is connected to the first telescopic plate; the second telescopic rack is disposed on the side of the drive rack 31 facing the second telescopic plate, and the second telescopic rack is connected to the second telescopic plate. A first gear is meshed with the first telescopic rack and the drive rack 31, respectively, and the drive rack 31 can drive the first telescopic rack to move via the first gear; a second gear is meshed with the second telescopic rack and the drive rack 31, respectively, and the drive rack 31 can drive the second telescopic rack to move via the second gear.

[0105] As shown in Figure 4 , optionally, sealing rings 25 are provided around the edges of the partition assembly 20 and the telescopic plate 21. These sealing rings 25 are made of a flexible material. When the telescopic plate 21 extends from the mounting interlayer, i.e., when the telescopic plate 21 moves in a first direction, the telescopic plate 21 pushes the sealing ring 25 outward. The sealing rings 25 around the partition assembly 20 abut against the drawer body 10 or the cover plate 11, sealing the dry area 13 and the wet area 14. When the telescopic plate 21 retracts into the mounting interlayer, i.e., when the telescopic plate 21 moves in a second direction, the portion of the sealing ring 25 located on the telescopic plate 21 contracts and disengages from the drawer body 10, preventing interference with the sliding movement of the partition assembly 20.

[0106] Optionally, a sealing groove is provided on the edge of the partition assembly 20 and / or the telescopic plate 21, and the sealing ring 25 can be installed in the sealing groove to prevent the sealing ring 25 from falling off.

[0107] As shown in FIG. 4 , optionally, the partition assembly 20 is further provided with a first sliding groove 23 , and the partition assembly 20 is slidingly connected to the edge of the drawer body 10 through the first sliding groove 23 , so that the partition assembly 20 can slide along the edge of the drawer body 10 .

[0108] Specifically, a first sliding groove 23 is provided on the upper edge of the partition assembly 20. The first sliding groove 23 extends outward to the edge of the drawer body 10. The edge of the drawer body 10 is engaged in the first sliding groove 23 so that the partition assembly 20 can slide along the edge of the drawer body 10. Engaging the edge of the drawer body 10 in the first sliding groove 23 can also prevent the partition assembly 20 from detaching from the drawer body 10.

[0109] Specifically, the first sliding groove 23 is provided at an end of the upper edge of the partition assembly 20 away from the telescopic plate 21 .

[0110] As shown in Figures 9 to 12 , the drawer assembly optionally further includes a rolling base 40. The rolling base 40 is mounted on the lower edge of the partition assembly 20, and includes a rolling portion that abuts against the bottom end surface of the drawer body 10.

[0111] Specifically, the rolling base 40 is disposed at the lower edge of the partition assembly 20, and the rolling portion of the rolling base 40 abuts against the bottom end surface of the drawer body 10. When the partition assembly 20 slides along the edge of the drawer body 10, the rolling portion rolls on the bottom end surface of the drawer body 10 to provide support, thereby improving the smoothness of the sliding of the partition assembly 20 and extending the service life of the partition assembly 20.

[0112] Optionally, the drawer assembly includes a plurality of rolling bases 40 , and the plurality of rolling bases 40 are evenly arranged at the lower edge of the partition assembly 20 along the length of the partition assembly 20 .

[0113] In some practical applications, the drawer assembly includes two rolling bases 40 , which are respectively disposed at two ends of the lower edge of the partition assembly 20 .

[0114] As shown in Figures 9 to 12, the rolling base 40 optionally includes a ball cover 41, a ball seat 42, and a ball 43. The ball 43 can be placed on the ball cover 41, and then the ball seat 42 is snapped onto the side of the ball 43 facing away from the ball cover 41 to secure the ball 43 to the ball cover 41. The side of the ball seat 42 facing away from the ball cover 41 is provided with a ball opening, and the diameter of the ball opening is smaller than the diameter of the ball 43. The ball 43 can protrude from the ball seat 42 through the ball opening, so that the ball 43 can abut against the drawer body 10 and roll relative to the drawer body 10.

[0115] As shown in Figures 9 to 12, the ball cover 41 is optionally provided with a snap-in 412, and the ball seat 42 is provided with a first hook 421 corresponding to the snap-in 412. When the ball seat 42 engages the ball 43 with the ball cover 41, the first hook 421 can be engaged with the snap-in 412 to prevent the ball seat 42 from being separated from the ball cover 41.

[0116] As shown in FIG9 , optionally, the first partition plate 203 and / or the second partition plate 204 are provided with a slot, and the edge of the ball bearing cover 41 is provided with a second hook 411 corresponding to the slot. The edge of the ball bearing cover 41 can slide into the slot, and then the second hook 411 is engaged with the slot to attach the ball bearing cover 41 to the first partition plate 203 and / or the second partition plate 204.

[0117] Optionally, the upper edge of the first side wall of the drawer body 10 is bent toward the partition assembly 20 , and the partition assembly 20 can abut against the upper edge of the first side wall to prevent the partition assembly 20 from falling out of the drawer body 10 .

[0118] As shown in Figure 1 , an embodiment of the present disclosure further provides a refrigeration device, which includes a housing and the aforementioned drawer assembly. The housing is provided with a storage cavity, wherein the drawer assembly is provided in the storage cavity.

[0119] Specifically, with the refrigeration device using the drawer assembly provided in the present application, the user can adjust the size of the dry area 13 and the wet area 14 by himself, thereby improving the user experience.

[0120] As shown in FIG3 , in some embodiments, a dehumidification port 15 is provided on the side wall of the dry area 13 of the drawer body 10 ; the refrigeration device further includes a dehumidification device that is connected to the dry area 13 through the dehumidification port 15 for dehumidifying the dry area 13 .

[0121] Specifically, the refrigeration equipment also includes a heat exchanger, which can function as a dehumidifier. The dehumidifier is connected to the dehumidification port 15 via an air duct and can dehumidify the dry area 13 through the dehumidification port 15 to ensure that the humidity in the dry area 13 is lower than that in the wet area 14. Users can store items requiring low humidity in the dry area 13 and items requiring high humidity in the wet area 14. Users can slide the partition assembly 20 toward the dry area 13 to increase the volume of the wet area 14, or they can slide the partition assembly 20 toward the wet area 14 to increase the volume of the dry area 13.

[0122] Optionally, the storage area of ​​the box body can be a freezer compartment or a refrigerator compartment.

[0123] As shown in FIG3 , in some embodiments, the refrigeration device further includes a position sensor 16. Position sensor 16 is disposed on the drawer body 10 and / or the partition assembly 20 and is electrically connected to the dehumidification device to detect the position of the partition assembly 20. When position sensor 16 detects that the partition assembly 20 has moved toward the dry area 13 to a first preset position, position sensor 16 may control the dehumidification device to stop dehumidifying the dry area 13.

[0124] Specifically, the position sensor 16 can detect the position of the partition assembly 20 within the drawer body 10 in real time. When the partition assembly 20 is in the first preset position, the storage area is completely the wet area 14. At this time, the partition assembly 20 can trigger the position sensor 16, causing the position sensor 16 to control the dehumidification device to stop dehumidifying the dry area 13, thereby preventing the dehumidification device from affecting the humidity in the wet area 14.

[0125] As shown in FIG3 , in some embodiments, position sensor 16 includes a magnetic switch and a magnetic element. The magnetic switch is located on the side of the drawer assembly located in the dry area 13. The magnetic element is located on the partition assembly 20 at a position corresponding to the magnetic switch. When the partition assembly 20 moves toward the dry area 13 to a first predetermined position, the magnetic element triggers the magnetic switch.

[0126] Specifically, a magnetic switch is fixedly mounted on one side of the drawer assembly located in the dry area 13, and the magnetic switch is electrically connected to the dehumidification device. When the partition assembly 20 moves toward the dry area 13 to a first preset position, the magnetic element disposed on the partition assembly 20 can trigger the magnetic switch. At this point, the magnetic switch can control the dehumidification device to stop dehumidifying the dry area 13 to avoid affecting the humidity in the wet area 14. When the partition assembly 20 moves toward the wet area 14 and leaves the first preset position, the magnetic element cannot trigger the magnetic switch. At this point, the magnetic switch is in the closed state, and the dehumidification device can dehumidify the dry area 13 through the dehumidification port 15.

[0127] As shown in FIG. 3 , optionally, the magnetic switch is provided at the end of the cover plate 11 on the dry area 13 side, and the magnetic element is provided at the upper edge of the partition assembly 20 .

[0128] As shown in FIG1 , in some embodiments, the refrigeration device further includes a moisture permeable membrane 12 . The moisture permeable membrane 12 is disposed corresponding to the wet area 14 . When the humidity in the wet area 14 is less than or equal to a preset humidity, the moisture permeable membrane 12 can block moisture in the wet area 14 .

[0129] Optionally, when the humidity in the wet area 14 is less than or equal to a preset humidity, the moisture-permeable membrane 12 can prevent moisture in the wet area 14 from leaking outward. When the humidity in the wet area 14 is greater than the preset humidity, moisture in the wet area 14 can leak outward through the moisture-permeable membrane 12 until the humidity in the wet area 14 is less than or equal to the preset humidity.

[0130] Optionally, the preset humidity is greater than or equal to 75% and less than or equal to 95%. For example, the preset humidity can be 75%, 80%, 85%, 90% or 95%.

[0131] In actual applications, the preset humidity can be determined according to the actual needs of the user. For example, the preset humidity is 90%.

[0132] It is understandable that after the user stores the items, some moisture may remain in the items themselves, and this moisture may evaporate into the wet area 14 to humidify the wet area 14 .

[0133] As shown in FIG. 1 , in some embodiments, the moisture-permeable membrane 12 is disposed at a position of the cover plate 11 corresponding to the wet area 14 , and the moisture-permeable membrane 12 is flush with the inner side surface of the cover plate 11 .

[0134] Specifically, an opening is provided on one side of the cover plate 11 located in the wet area 14 to connect the wet area 14 with the external environment, and a moisture-permeable membrane 12 is provided at the opening to control the humidity in the wet area 14. The moisture-permeable membrane 12 is provided flush with the inner side surface of the cover plate 11 to prevent the moisture-permeable membrane 12 from interfering with the movement of the partition assembly 20.

[0135] It is understandable that, since the humidity of the storage chamber of the refrigeration equipment is generally low, when the partition assembly 20 slides toward the wet area 14 to position the moisture permeable membrane 12 in the dry area 13 , moisture in the storage chamber cannot enter the dry area 13 through the moisture permeable membrane 12 .

[0136] As shown in FIG3 , in some embodiments, a dehumidification port 15 is provided in the drawer body 10 . Seals 24 are provided in the partition assembly 20 and corresponding to the dehumidification port 15 . When the partition assembly 20 moves toward the dry area 13 to a first preset position, the seals 24 can seal the dehumidification port 15 .

[0137] Specifically, the dehumidification opening 15 is provided on the sidewall of the drawer body 10 on the dry area 13 side, and a sealing sponge is provided corresponding to the partition assembly 20 and the dehumidification opening 15 to form a seal 24. When the partition assembly 20 moves toward the dry area 13 to a first preset position, the sealing sponge can block the dehumidification opening 15 to further prevent the dehumidification device or the external environment from affecting the humidity in the wet area 14.

[0138] As shown in FIG3 , in some embodiments, the refrigeration device further includes a temperature sensor 17 . The temperature sensor 17 is disposed in the drawer assembly and is used to detect the temperature of the dry area 13 .

[0139] Specifically, the temperature sensor 17 is used to detect the temperature of the dry area 13 , and the temperature sensor 17 is electrically connected to the dehumidification device, and the dehumidification efficiency of the dehumidification device can be controlled according to the temperature of the dry area 13 .

[0140] Optionally, the temperature sensor 17 is disposed at an edge of the cover plate 11 on one side of the dry area 13 .

[0141] Example 2

[0142] The difference between this embodiment and embodiment 1 is that:

[0143] 13 to 15 , the drawer assembly includes a connecting rod assembly and a drive block 36 , which is movably mounted in the mounting interlayer; the connecting rod assembly is used to connect the drive block 36 and the telescopic plate 21 , where the telescopic plate 21 is a side telescopic plate. The drive block 36 can drive the telescopic plate 21 to slide along a preset track in the mounting interlayer through the connecting rod assembly, so that the telescopic plate 21 extends out of the mounting interlayer and abuts against the side wall of the drawer body 10 , or the telescopic plate 21 is retracted into the mounting interlayer and detached from the side wall of the drawer body 10 .

[0144] The drive block 36 can move vertically within the mounting interlayer. A connecting rod assembly is disposed within the mounting interlayer, connecting the drive block 36 and the telescopic plate 21, as shown in Figure 13. The user can move the drive block 36 upward, causing it to retract the telescopic plate 21 into the mounting interlayer and disengage it from the sidewall of the drawer body 10 via the connecting rod assembly. The user can then slide the partition assembly 20 within the drawer body 10 to adjust the volume of the dry area 13 and the wet area 14. After adjustment is complete, the drive block 36 can be moved downward, causing it to extend the telescopic plate 21 out of the mounting interlayer and abut against the sidewall of the drawer body 10, preventing the partition assembly 20 from sliding.

[0145] As shown in FIG13 , in some embodiments, the connecting rod assembly includes a first connecting rod 351, a second connecting rod 352, and a third connecting rod 353. The first connecting rod 351 includes a first end rotatably connected to the driving block 36; the second connecting rod 352 includes a first end rotatably connected to the first connecting rod 351 and a second end rotatably connected to the telescopic plate 21; and the third connecting rod 353 includes a first end rotatably connected to the partition assembly 20 and a second end rotatably connected to the first end of the second connecting rod 352.

[0146] Specifically, the first connecting rod 351 includes a first end and a second end that are oppositely disposed, and the first end is rotatably connected to the driving block 36. The first end of the second connecting rod 352 is rotatably connected to the second end of the first connecting rod 351, and the second end is rotatably connected to the telescopic plate 21. The first end of the third connecting rod 353 is rotatably disposed on the first partition 203 or the second partition 204, and the second end is rotatably connected to the first end of the second connecting rod 352. The connection between the second end of the first connecting rod 351 and the first end of the second connecting rod 352 is a first connection, and the connection between the second end of the third connecting rod 353 and the first end of the second connecting rod 352 is a second connection. The first connection and the second connection are arranged to overlap.

[0147] As shown in Figure 13, in some embodiments, the first end of the first connecting rod 351 is higher than the first end of the second connecting rod 352; the second end of the second connecting rod 352 is higher than the first end of the second connecting rod 352; the first end of the third connecting rod 353 is higher than the first end of the second connecting rod 352, and the first end of the third connecting rod 353 is located on the side of the first end of the second connecting rod 352 close to the driving block 36.

[0148] Specifically, the first end of the third connecting rod 353 is located above the first end of the first connecting rod 351. When the drive block 36 moves upward, it can drive the first connecting rod 351 to move. At the same time, because the first end of the third connecting rod 353 is mounted on the partition assembly 20, the second end of the first connecting rod 351 rotates around the first end toward the drive block 36, thereby driving the second end of the second connecting rod 352 to rotate around the first end toward the drive block 36. At this time, the second end of the second connecting rod 352 can drive the telescopic plate 21 to retract into the mounting interlayer. Similarly, when the drive block 36 moves downward, it can drive the second end of the first connecting rod 351 to rotate away from the drive block 36, thereby driving the telescopic plate 21 out of the mounting interlayer through the second connecting rod 352.

[0149] As shown in FIG13 , in some embodiments, the connecting rod assembly further includes a fourth connecting rod 354 and a fifth connecting rod 355. The fourth connecting rod 354 includes a first end rotatably connected to the partition assembly 20; the fifth connecting rod 355 includes a first end rotatably connected to the fourth connecting rod 354 and a second end rotatably connected to the telescopic plate 21; wherein the first end of the fourth connecting rod 354 is on the same vertical line as the first end of the first connecting rod 351.

[0150] Specifically, the fourth connecting rod 354 includes a first end and a second end that are arranged opposite each other, and the first end is rotatably connected to the first partition plate 203 and / or the second partition plate 204. When the drive block 36 drives the telescopic plate 21 via the first connecting rod 351 and the second connecting rod 352, the telescopic plate 21 can drive the fourth connecting rod 354 and the fifth connecting rod 355 to move simultaneously. The first end of the fifth connecting rod 355 is rotatably connected to the second end of the fourth connecting rod 354, and the second end of the fifth connecting rod 355 is rotatably connected to the telescopic plate 21. The second end of the fifth connecting rod 355 and the second end of the second connecting rod 352 are not at the same horizontal height. This arrangement can improve the stability of the telescopic plate 21 during movement.

[0151] As shown in Figure 13, in some embodiments, the first end of the fourth link 354 is located below the first end of the first link 351; the first end of the fifth link 355 is located above the first end of the second link 352; and the second end of the fifth link 355 is located below the second end of the second link 352.

[0152] Specifically, the second end of the second connecting rod 352 is connected to the upper half of the telescopic plate 21, and the second end of the fifth connecting rod 355 is connected to the lower half of the telescopic plate 21. In this way, the second connecting rod 352 and the fifth connecting rod 355 can respectively drive the upper half and the lower half of the telescopic plate 21 to move, thereby further improving the stability of the telescopic plate 21 during movement.

[0153] As shown in FIG13 , in some embodiments, the connecting rod assembly further includes a sixth connecting rod 356 . The sixth connecting rod 356 includes a first end rotatably connected to the first end of the fifth connecting rod 355 and a second end rotatably connected to the second connecting rod 352 .

[0154] Specifically, the ends of the sixth connecting rod 356 are connected to the fifth connecting rod 355 and the second connecting rod 352, respectively, and the second end of the sixth connecting rod 356 is connected to the middle of the second connecting rod 352. This arrangement ensures stability when the fourth connecting rod 354 drives the fifth connecting rod 355 to rotate toward or away from the driving block 36.

[0155] As shown in FIG13 , in some embodiments, the drawer assembly further includes a lower telescopic plate 27. The lower telescopic plate 27 is slidably disposed within the mounting interlayer of the partition assembly and is disposed corresponding to the bottom wall of the drawer body 10. The lower telescopic plate 27 is fixedly connected to the drive block 36 so that the lower telescopic plate 27 drives the drive block 36 to move vertically.

[0156] Specifically, the lower telescopic plate 27 is installed within the mounting interlayer, positioned relative to the bottom wall of the storage area. The lower telescopic plate 27 is vertically slidable within the mounting interlayer. This allows the user to press downward on the shelf assembly 20, causing the lower telescopic plate 27 to move the drive block 36 upward relative to the shelf assembly 20, thereby retracting the telescopic plate 21 into the mounting interlayer. This arrangement makes it easier for the user to adjust the position of the shelf assembly 20.

[0157] As shown in Figures 13 to 15 , in some embodiments, the drawer assembly further includes a second elastic member 28. The second elastic member 28 is disposed within the mounting interlayer, with its ends connected to the lower telescopic plate 27 and the partition assembly 20, respectively. The second elastic member 28 can push the lower telescopic plate 27 toward the bottom wall of the drawer body 10.

[0158] Specifically, the first or second partition 203, 204 is provided with a fixing seat 29, which is located above the lower telescopic plate 27. The ends of the second elastic element 28 are respectively connected to the fixing seat 29 and the lower telescopic plate 27, so that the second elastic element 28 pushes the lower telescopic plate 27 downward. In this way, when the user releases the partition assembly 20, the second elastic element 28 pushes the lower telescopic plate 27 downward, driving the driving block 36 downward, and further driving the telescopic plate 21 to extend out of the mounting interlayer.

[0159] As shown in FIG13 , the drawer assembly optionally includes a plurality of second elastic elements 28, and the plurality of second elastic elements 28 are arranged along the length of the lower telescopic plate 27. The first partition plate 203 or the second partition plate 204 and the plurality of second elastic elements 28 are provided with a plurality of fixing seats 29, so that the plurality of second elastic elements 28 can simultaneously push the lower telescopic plate 27 downward.

[0160] As shown in FIG14 , the driving block 36 may optionally be provided with an escape groove 361 at one end thereof adjacent to the lower telescopic plate 27, and at least one second elastic element 28 may be mounted within the escape groove 361. The second elastic element 28 mounted within the escape groove 361 has its two ends connected to the upper wall of the escape groove 361 and the lower telescopic plate 27, respectively.

[0161] As shown in FIG15 , the partition assembly 20 is optionally provided with a limit portion 205, and the lower telescopic plate 27 is provided with a limit fitting portion 271 corresponding to the limit portion 205. When the lower telescopic plate 27 moves downward to the second preset position, the limit portion 205 can stop the limit fitting portion 271 to prevent the lower telescopic plate 27 from continuing to move downward and causing the lower telescopic plate 27 to separate from the mounting interlayer.

[0162] As shown in Figure 13, optionally, the drawer assembly is provided with two sets of telescopic plates 21, and the two sets of telescopic plates 21 are oppositely arranged on both sides of the partition assembly 20. The driving block 36 is respectively connected to the two sets of telescopic plates 21 through a connecting rod assembly.

[0163] Specifically, the two sets of telescopic plates 21 are respectively a first side telescopic plate and a second side telescopic plate. That is, the drawer assembly includes a first side telescopic plate positioned corresponding to the first side wall, and a second side telescopic plate positioned corresponding to the second side wall. The first connecting rod 351, the second connecting rod 352, the third connecting rod 353, the fourth connecting rod 354, the fifth connecting rod 355, and the sixth connecting rod 356 are respectively provided in two sets corresponding to the first and second side telescopic plates. This allows the drive block 36, via the connecting rod assembly, to respectively drive the two sets of telescopic plates to extend or retract into the mounting interlayer. When extending from the mounting interlayer, the first side telescopic plate abuts the first side wall, while when extending from the mounting interlayer, the second side telescopic plate abuts the second side wall.

[0164] In this embodiment, a sealing ring is mounted around the edges of the partition assembly 20, the telescopic plate 21, and / or the lower telescopic plate 27. When the telescopic plate 21 and / or the lower telescopic plate 27 extend out of the mounting interlayer, the plates 21 and / or the lower telescopic plate 27 push the sealing ring 25 outward. The sealing ring 25 surrounding the partition assembly 20 abuts against the drawer body 10 or the cover plate 11, sealing the dry area 13 and the wet area 14. When the telescopic plate 21 and / or the lower telescopic plate 27 retract into the mounting interlayer, the portion of the sealing ring 25 located on the plates 21 and / or the lower telescopic plate 27 retracts and disengages from the drawer body 10 to prevent interference with the sliding of the partition assembly 20.

[0165] Optionally, sealing grooves are provided on the edges of the partition assembly 20 , the side telescopic plates 21 and / or the lower telescopic plate 22 , and the sealing ring 25 can be installed in the sealing grooves to prevent the sealing ring 25 from falling off.

[0166] Except for the above differences, Example 2 is the same as Example 1 and will not be described in detail here.

[0167] Example 3

[0168] In this embodiment, the drawer assembly includes the aforementioned drawer body 10 , the aforementioned partition assembly 20 , and also includes a locking device, wherein the locking device includes the aforementioned telescopic plate 21 .

[0169] The difference between this embodiment and embodiment 1 is that:

[0170] 16 to 20 , a locking device is slidably disposed within the mounting interlayer of the partition assembly 20.
