[0045] The refrigeration device provided by the embodiment of the present disclosure is used to place food and other items for refrigeration by arranging multiple shelves 300 in the storage cavity 210, and store food and other items on shelves 300 at different heights. When the target shelf 300 for taking and placing food is determined, the lifting frame 400 can be driven to move to the height of the shelf 300, and then the lifting frame 400 is driven to connect with the target shelf 300, and the target shelf 300 is driven to rotate and extend out of the storage cavity 210 through the rotation of the lifting frame 400, and then the target shelf 300 is driven to rise and fall to the required height position through the lifting frame 400, so as to adapt to users of different heights to take and place food, better meet the needs of users to take and place food, and improve the user experience. Since each shelf board 300 can be connected to the lifting frame 400, the lifting frame 400 can drive each shelf board 300 to independently rotate and extend out of the storage cavity 210, and then be lifted to a desired height position, thereby reducing the lifting impact between the multiple shelf boards 300 when there are multiple vertically arranged shelf boards 300.

[0046] Optionally, the housing 200 is vertically arranged, and the storage cavity 210 defined inside the housing 200 is also a vertically arranged cavity structure, and the plurality of shelves 300 are evenly arranged inside the storage cavity 210 along the vertical direction. In this way, the housing 200 and the storage cavity 210 defined inside the housing 200 are both vertically arranged, so that the plurality of shelves 300 are evenly arranged along the vertical direction, and food and other items can be stored in layers, meeting the storage needs of users at different heights, and reducing the space occupied by the refrigeration device in the horizontal direction.

[0047] Optionally, the refrigeration device is a refrigerator.

[0048] Optionally, the plurality of shelves 300 are all placed horizontally. In this way, the stability of the food and other items placed on the plurality of shelves 300 is higher, and the food and other items are not easy to fall during the rotation and lifting of the shelves 300.

[0049] Optionally, each shelf 300 is slidably connected to the inner wall of the storage cavity 210. In this way, each shelf 300 can be independently rotated and extended out of the storage cavity 210 when driven.

[0050] Optionally, a support is provided at the position of each shelf board 300 on the inner wall of the storage cavity 210 corresponding to the position of each shelf board 300, and the lower side of each shelf board 300 is slidably connected to the corresponding support. In this way, each shelf board 300 is slidably connected to the inner wall of the storage cavity 210 through the corresponding support, and the support is provided to support the shelf board 300, thereby reducing the support contact area of ​​the shelf board 300 and reducing the sliding friction between the shelf board 300 and the support when the shelf board 300 rotates, so that the shelf board 300 can rotate more smoothly to extend or retract into the storage cavity 210.

[0051] Optionally, the refrigeration device further includes: a door body 500. One side of the door body 500 is rotatably connected to one side of the housing 200, and the access opening 211 is opened or closed by rotating the door body 500. In this way, the access opening 211 is closed by the door body 500, thereby closing the storage cavity 210. When it is necessary to access or place items, the door body 500 is rotated to open, so that the shelf 300 can be rotated along the access opening 211 and extend out of the storage cavity 210, so as to facilitate access to or placement of items.

[0052] Optionally, the door body 500 is adapted to the shape of the housing 200, and the vertical side of the door body 500 is rotatably connected to the vertical side of the housing 200 through a hinge, and the interior of the door body 500 also defines a storage space. In this way, the housing 200 and the door body 500 are equally divided, so that the storage space defined inside the door body 500 can also be used for storage, thereby improving the space utilization rate of the refrigeration device.

[0053] Optionally, the storage cavity 210 defined inside the housing 200 is a semi-cylindrical cavity, and the shape of the shelf 300 is adapted to the shape of the cross section of the storage cavity 210. In this way, the shelf 300 can smoothly rotate in the storage cavity 210, facilitating the extension and retraction of the shelf 300, and preventing the inner wall of the storage cavity 210 from blocking the rotation of the shelf 300.

[0054] Optionally, the housing 200 is a semi-cylindrical structure, the door 500 is also a semi-cylindrical structure, and the storage space defined inside the door 500 is also a semi-cylindrical cavity. In this way, the space utilization inside the housing 200 and the door 500 can be improved, and the rotation of the shelf 300 is convenient.

[0055] Optionally, a plurality of vertically arranged shelves 300 are also provided in the storage space defined inside the door body 500, and each shelf 300 can also rotate and extend out of the storage space, and can be raised and lowered in the vertical direction. In this way, a plurality of shelves 300 of different heights are also provided in the storage space inside the door body 500, so as to realize classified storage at different heights and make full use of the internal space of the refrigeration device. When the target shelf 300 for taking and placing items is located in the shelf 300 inside the door body 500, the target shelf 300 is controlled to rotate and extend out of the door body 500, and then raised and lowered to the height required by the user, thereby improving the user's experience of taking and placing items.

[0056] Optionally, when multiple shelves 300 are also arranged inside the door body 500, the multiple shelves 300 inside the door body 500 are staggered in the vertical direction with the multiple shelves 300 inside the housing 200. In this way, when the target shelves 300 are located inside the housing 200 and the door body 500, respectively, it is necessary to drive the housing 200 and the target shelves 300 inside the door body 500 to rotate and extend at the same time. In order to avoid interference between the rotation of the shelves 300 inside the door body 500 and the housing 200, the multiple shelves 300 inside the door body 500 and the multiple shelves 300 inside the housing 200 are staggered in the vertical direction.

[0057] Optionally, a roller 510 is provided at the lower end of the door body 500 to support the door body 500. In this way, since the housing 200 and the door body 500 are equally divided, the door body 500 is relatively large in size, and multiple shelves 300 are provided inside the door body 500 to place items, which also increases the weight of the door body 500. Therefore, a roller 510 is provided at the lower end of the door body 500, and the roller 510 is used to support the door body 500, thereby reducing the risk of the door body 500 pulling the housing 200 and causing the refrigeration device to tilt.

In this way, the lifting frame 400 is sleeved on the outside of the guide rod 220, and the lifting and lowering of the lifting frame 400 can be guided by the guide rod 220, so that the lifting frame 400 can be accurately lifted to the height required by the user, and at the same time, the guidance of the guide rod 220 can enable the lifting frame 400 to be accurately lifted to the position of the target shelf 300 and stably connected to the target shelf 300. The guide rod 220 can support the lifting frame 400 during the lifting and lowering process of the lifting frame 400, and the lifting frame 400 is not easy to tilt, so that the shelf 300 driven by the lifting frame 400 is not easy to tilt, and the stability is higher.

[0059] Optionally, the guide rod 220 is located in the plane where the access opening 211 is located. In this way, the lifting frame 400 sleeved on the outer side of the guide rod 220 can be lifted and lowered along the plane where the access opening 211 is located, and is better connected with the target shelf 300.

[0060] Optionally, a first driving unit 230 is provided at the upper end of the guide rod 220, and the output end of the first driving unit 230 is connected to the guide rod 220, and can drive the guide rod 220 to rotate, thereby driving the lifting frame 400 sleeved on the outer side of the guide rod 220 to rotate. In this way, the guide rod 220 can be driven to rotate by the first driving unit 230, so that the lifting frame 400 is driven to rotate by the guide rod 220. When the lifting frame 400 is lifted to the target height and connected to the target shelf 300, the guide rod 220 is driven to rotate to drive the target shelf 300 to extend out of the storage cavity 210 as the guide rod 220 rotates. The guide rod 220 can guide the lifting frame 400 while also driving the lifting frame 400 to rotate, thereby improving the stability of the rotation of the lifting frame 400 and reducing costs.

In this way, the first driving part 230 is hidden and installed in the inner wall of the shell 200, and the first driving part 230 is used to drive the rotation of the guide rod 220, and the lower end of the guide rod 220 is rotatably connected to the inner wall of the shell 200, so that the support stability of the guide rod 220 is stronger and it is driven more smoothly by the first driving part 230.

[0062] Optionally, the first driving part 230 is a driving motor. In this way, the guide rod 220 is driven to rotate by the driving motor, which improves the rotation efficiency of the guide rod 220 and has strong rotation stability.

[0063] Optionally, the guide rod 220 is a rectangular rod-shaped structure, a rectangular groove 410 is provided inside the lifting frame 400, and the guide rod 220 is provided through the rectangular groove 410. In this way, the rectangular groove 410 structure can be used to limit the lifting frame 400, so that the lifting frame 400 cannot rotate relative to the guide rod 220. When the guide rod 220 rotates, the lifting frame 400 rotates synchronously with the guide rod 220, thereby improving the rotation stability of the lifting frame 400.

[0064] Optionally, a rectangular support sleeve 420 is disposed below the lifting frame 400, the upper end of the rectangular support sleeve 420 is connected to the lifting frame 400, and the upper end of the rectangular support sleeve 420 is connected to the rectangular groove 410, and the guide rod 220 is sequentially disposed through the rectangular groove 410 and the rectangular support sleeve 420. In this way, the rectangular support sleeve 420 is used to further support the lifting frame 400, thereby increasing the support area of ​​the lifting frame 400 and the guide rod 220, further improving the stability of the lifting frame 400, and making the lifting frame 400 less likely to tilt during the lifting process, thereby improving the stability of the target shelf 300 connected to the lifting frame 400.

[0065] Optionally, the refrigeration device further includes: a lifting chain 600. The lifting chain 600 is vertically arranged at the edge of one side of the access opening 211, and one end of the lifting frame 400 is meshed with the lifting chain 600. In this way, the lifting frame 400 is driven to be lifted and lowered by setting the lifting chain 600, so that the lifting frame 400 is lifted and lowered to the height required by the user. The lifting frame 400 adopts a connection method of meshing with the lifting chain 600, so that the lifting frame 400 itself can rotate relative to the lifting chain 600, and the lifting frame 400 is always connected to the lifting chain 600, so as to ensure the lifting and lowering drive of the lifting frame 400.

[0066] Optionally, the lifting chain 600 is arranged at the rear side of the guide rod 220. In this way, the lifting frame 400 sleeved on the outer side of the guide rod 220 can be better engaged and connected with the lifting chain 600.

[0067] Optionally, a chain groove is provided on the inner wall of the storage cavity 210 corresponding to the rear of the guide rod 220, and the lifting chain 600 is installed in the chain groove, and a portion of the lifting chain 600 extends toward the guide rod 220. In this way, the lifting chain 600 is hidden in the chain groove, which reduces the erosion of the lifting chain 600 by water vapor in the storage cavity 210 and prolongs the service life of the lifting chain 600.

[0068] It can be understood that the front side of the guide rod 220 is the side of the guide rod 220 facing the door body 500 , and the rear side of the guide rod 220 is the side of the guide rod 220 facing away from the door body 500 .

[0069] Optionally, a driving wheel 610 is provided in the upper end area inside the chain groove, a driven wheel 620 is provided in the lower end area, the lifting chain 600 is sleeved on the outside of the driving wheel 610 and the driven wheel 620, a second driving part 630 is provided on one side of the driving wheel 610, and the output end of the second driving part 630 is connected to the center of the driving wheel 610. In this way, the lifting chain 600 is supported by the cooperation of the driving wheel 610 and the driven wheel 620, and the second driving part 630 is used to drive the driving wheel 610 to rotate, thereby driving the lifting chain 600 to rotate, thereby driving the lifting frame 400 to rise and fall.

[0070] Optionally, the lifting chain 600 is provided with an engagement groove 640 on the side wall facing the lifting frame 400, and an engagement portion 430 is formed at one end of the lifting frame 400, and the engagement portion 430 is movably embedded in the engagement groove 640. In this way, by movably embedding the engagement portion 430 formed at one end of the lifting frame 400 in the engagement groove 640, the lifting frame 400 can be driven to rotate independently by the guide rod 220 while being driven to lift by the lifting chain 600. The movable embedding of the engagement portion 430 enables the lifting frame 400 to always remain in a state of engagement with the engagement groove 640 during the rotation process, so that the lifting frame 400 is not easily separated from the drive of the lifting chain 600.

[0071] Optionally, in the horizontal direction, the width of the meshing portion 430 is greater than the width of the meshing slot 640, so that the lifting frame 400 always maintains a meshing state with the lifting chain 600 during the rotation process. In this way, since the lifting chain 600 drives the lifting frame 400 to rise and fall in the vertical direction, and the lifting frame 400 itself can rotate in the horizontal direction to extend or retract into the storage cavity 210, the meshing portion 430 is embedded in the meshing slot 640 in the horizontal direction. The width of the meshing portion 430 is set to be greater than the width of the meshing slot 640, so that the meshing portion 430 always maintains a meshing connection state with the meshing slot 640 during the rotation process of the lifting frame 400, thereby improving the connection stability between the lifting frame 400 and the lifting chain 600.

[0072] Optionally, in the horizontal direction, the width of the meshing portion 430 is twice the width of the meshing slot 640. In this way, when the lifting frame 400 rotates at a relatively large angle, the meshing portion 430 can still maintain the meshing state with the meshing slot 640, further improving the connection stability between the lifting frame 400 and the lifting chain 600.

[0073] Alternatively, if Figure 8 and Fig. 9 As shown, a slot 310 is provided at the end of each shelf 300, and an insertion rod 440 is provided on the lifting frame 400. When the lifting frame 400 is connected to any shelf 300, the insertion rod 440 is inserted into the slot 310 provided at the end of the shelf 300. In this way, the lifting frame 400 can be connected to any shelf 300 by inserting the insertion rod 440 into the slot 310, thereby improving the connection stability between the lifting frame 400 and the shelf 300, and using the lifting frame 400 to form a more stable support for the shelf 300, so that the shelf 300 is not easy to tilt during the rotation and lifting process.

[0074] Optionally, the insertion rod 440 is a rectangular rod-shaped structure, and the shape of the slot 310 is adapted to the insertion rod 440. In this way, the insertion rod 440 cooperates with the slot 310 to form a limit, preventing the shelf 300 and the insertion rod 440 from rotating relative to each other, and the lifting frame 400 drives the shelf 300 to rotate, extend or retract into the storage cavity 210 more stably.

[0075] Optionally, the insertion rod 440 is vertically arranged, and the lower end of the insertion rod 440 is fixedly connected to the upper side wall of the lifting frame 400. In this way, the insertion rod 440 can be smoothly inserted into the slot 310 of the target shelf 300 and connected thereto as the lifting frame 400 is raised and lowered, and the insertion rod 440 is used to form a stable support for the target shelf 300.

[0076] Optionally, a conical head 441 is provided at the upper end of the insertion rod 440. In this way, the setting of the conical head 441 can guide the insertion of the insertion rod 440, so that the insertion rod 440 can be more smoothly inserted into the slot 310 and connected thereto.

[0077] Optionally, the lifting frame 400 is a rectangular plate-shaped structure, one end of the lifting frame 400 is sleeved on the outside of the guide rod 220, and the engaging portion 430 is located at the sleeved end of the lifting frame 400, and the lower end of the insertion rod 440 is fixedly connected to the upper side wall corresponding to the other end of the lifting frame 400. In this way, the lifting frame 400 has a certain torque when rotating, and the insertion rod 440 at the end of the lifting frame 400 can smoothly rotate to the bottom of the slot 310 of the shelf 300 when the guide rod 220 rotates, and the insertion rod 440 can be accurately inserted into the slot 310 to connect with it.

[0078] Optionally, the slots 310 provided at the ends of each shelf 300 penetrate the shelf 300 in the vertical direction, and the length of the insertion rod 440 in the vertical direction is greater than the depth of the slots 310. In this way, when the lifting frame 400 is connected to the shelf 300 through the insertion rod 440, the insertion rod 440 can penetrate the slots 310 and pass out from the upper side wall of the shelf 300, thereby increasing the contact area between the insertion rod 440 and the slot 310, further improving the supporting stability of the insertion rod 440, and the shelf 300 is not easy to tilt during the rotation and lifting of the lifting frame 400.

[0079] Optionally, the refrigeration device further includes: an information acquisition module. The information acquisition module is used to acquire the height of the user and the target shelf 300 for taking and placing food. In this way, the height of the user and the target shelf 300 for taking and placing food are acquired through the information acquisition module, and the target shelf 300 is adjusted to the height required by the user according to the height of the user, so that the user can take and place food comfortably.

[0080] In some instances, when a user needs to take or place food, the refrigeration device obtains the user's height and the target shelf 300 for taking or placing food through the information acquisition module, determines the target height of the target shelf 300 according to the user's height, controls the lifting chain 600 to drive the lifting frame 400 to move to the bottom of the target shelf 300, controls the guide rod 220 to rotate and drive the insertion rod 440 of the lifting frame 400 to rotate to the bottom of the slot 310 of the target shelf 300, controls the lifting chain 600 to drive the lifting frame 400 to rise again, inserts the insertion rod 440 into the slot 310 of the target shelf 300, and connects the lifting frame 400 to the target shelf 300, then controls the guide rod 220 to rotate again to drive the target shelf 300 to rotate and extend out of the storage cavity 210, then controls the lifting chain 600 to drive the lifting frame 400 to rise and fall, drives the target shelf 300 to the target height, and the user takes or places food on the target shelf 300. After the food is taken and placed, the lifting chain 600 is controlled to drive the lifting frame 400 to be lifted to the placement height of the target shelf 300, and then the guide rod 220 is controlled to rotate to retract the target shelf 300 into the storage cavity 210, and then the lifting chain 600 is controlled to descend to disengage the insertion rod 440 from the slot 310, and then the guide rod 220 is controlled to rotate again to rotate the lifting frame 400 out of the storage cavity 210, and the lifting chain 600 is controlled to drive the lifting frame 400 to be lifted to the initial position.

[0082] In addition, the logic instructions in the memory 101 described above may be implemented in the form of software functional units and when sold or used as independent products, may be stored in a computer-readable storage medium.

[0083] The memory 101 is a computer-readable storage medium that can be used to store software programs and computer executable programs, such as program instructions / modules corresponding to the method in the embodiment of the present disclosure.

[0085] An embodiment of the present disclosure provides a refrigeration device, comprising the above-mentioned control device for refrigeration equipment.

[0086] Combination Fig.11 As shown, in some embodiments, a control method for a refrigeration device includes:

[0087] S01, the processor obtains the height of the target user and the target shelf for placing food;

[0088] S02, the processor determines a target lifting height of a target shelf according to the height of a target user;

[0089] S03, the processor controls the lifting frame to move to the position where the target shelf is located and connect with the target shelf;

[0090] S04, the processor controls the lifting frame to rotate to drive the target shelf plate to extend out of the storage cavity, and controls the lifting frame to move up and down to drive the target shelf plate to move up and down to a target lifting height.

[0091] With the control method for refrigeration equipment provided by the embodiment of the present disclosure, when a user has the need to take or place items, the processor obtains the height of the target user and the target shelf, and then determines the target lifting height of the target shelf according to the height of the target user, and then controls the lifting frame to move to the target shelf to connect with it, and drives the target shelf to extend out of the storage cavity and lift to the target lifting height, so that the user can take or place items. The control process has a high degree of automation, does not require the participation of the user, and improves the user's experience of taking or placing items.

[0092] Optionally, the target user is a user who is in front of the refrigeration device and has the need to take or place food.

[0093] Optionally, the processor determines a target shelf from a plurality of shelves.

[0094] Optionally, the processor obtains the height of the target user and the target shelf for placing the food, including: the processor obtains the height of the target user and the target shelf for placing the food sent by the information acquisition module.

[0095] Optionally, the information acquisition module includes: a camera and a touch panel. In this way, the height of the target user can be collected through the camera and sent to the processor, and the information about the target shelf manually input by the user can be received through the touch panel and sent to the processor.

[0096] A camera and a touch panel are arranged on the door body of the refrigeration equipment. The touch panel displays button information corresponding to multiple shelves. Each shelf corresponds to a button, and personalized information of the shelf is displayed on each button. The personalized information is the type of food stored on the shelf. The user selectively presses one or more buttons to determine the target shelf corresponding to the button according to the needs of taking and placing the food. The touch panel sends the information selected by the user to the processor, and the processor can determine the target shelf.

[0097] For example, there are three shelves in the storage cavity, namely shelf No. 1, shelf No. 2 and shelf No. 3, and three buttons are correspondingly set on the touch panel, namely button No. 1, button No. 2 and button No. 3, and "meat ingredients" is displayed on button No. 1, "vegetable ingredients" is displayed on button No. 2, and "egg ingredients" is displayed on button No. 3. When the user needs to take out meat ingredients from shelf No. 1, the user presses button No. 1, and the press signal is sent to the processor, and the processor determines that shelf No. 1 is the target shelf.

[0098] Optionally, the processor determines the target lifting height of the target shelf according to the height of the target user, including: the processor determines the target lifting height according to the height range of the target user. In this way, the processor pre-stores the lifting heights corresponding to different height ranges. Since the required pick-up and drop heights of users with similar height differences may not differ much, the target lifting height is determined according to the height range of the user's height, so that the control logic is simpler and the target lifting height is determined more efficiently.

[0099] Exemplarily, multiple height ranges are pre-stored in the processor, each height range corresponds to a lifting height, and the processor determines the target lifting height corresponding to the height range according to the height range of the target user and according to the correspondence between the multiple height ranges and the multiple lifting heights.

[0100] Optionally, the processor controls the lifting frame to move to the position where the target shelf is located and connects to the target shelf. In this way, the processor determines the target height corresponding to the position where the target shelf is located; the processor controls the lifting frame to move to the target height, and controls the lifting frame to rotate to the bottom of the target shelf so that the insertion rod of the lifting frame is located directly below the slot of the target shelf; the processor controls the lifting frame to rise to a set height so that the insertion rod is inserted into the slot of the target shelf. In this way, since the lifting frame can be plugged into the slot of any shelf board through the insertion rod, the lifting frame is connected to any shelf board. Therefore, the processor determines the target height of the target shelf board while determining the target shelf board, the processor controls the lifting frame to move to the target height, and controls the lifting frame to rotate to the bottom of the target shelf board so that the insertion rod is located directly below the slot of the target shelf board, and controls the lifting frame to rise so that the insertion rod is inserted into the slot and connected to the target shelf board.

[0101] Specifically, the height is set to be the movement height of the insertion rod that can penetrate the slot, so that the insertion rod can penetrate the slot and be stably connected to the target shelf.

[0102] Optionally, the processor controls the lifting frame to rotate to below the target shelf board, including: the processor controls the lifting frame to rotate to a first set angle so that the insertion rod of the lifting frame is located directly below the slot of the target shelf board.

[0103] Optionally, the processor controls the lifting frame to rotate to drive the target shelf board to extend out of the storage cavity, and controls the lifting frame to lift and lower to drive the target shelf board to a target lifting height, including: the processor controls the lifting frame to rotate to a second set angle to drive the target shelf board to extend out of the storage cavity; the processor determines the target lifting position of the lifting frame according to the target lifting height, controls the lifting frame to lift to the target lifting position, and drives the target shelf board to lift to the target lifting height. In this way, since each shelf board is located in the storage cavity, when the shelf board needs to be rotated and extended, the angle of rotation of each shelf board is the same, so the processor controls the lifting frame to rotate to the second set angle, so that the target shelf board is driven to rotate and extend. Since there is a height difference between the lifting frame and the target shelf board, after determining the target lifting height, the processor determines the target lifting position of the lifting frame according to the target lifting height, and controls the lifting frame to lift to the target lifting position.

[0104] It can be understood that the processor controls the rotation of the lifting frame to essentially control the first drive unit to drive the guide rod to rotate, and then drives the lifting frame to rotate through the guide rod; the processor controls the lifting of the lifting frame to essentially control the second drive unit to drive the lifting chain to rotate, and then drives the lifting frame to rise and fall through the lifting chain.

[0105] Optionally, the first setting angle and the second setting angle are both 90 degrees.

[0106] An embodiment of the present disclosure provides a computer-readable storage medium storing computer-executable instructions, wherein the computer-executable instructions are configured to execute the above-mentioned control method for a refrigeration device.

[0107] The technical solution of the embodiment of the present disclosure can be embodied in the form of a software product, which is stored in a storage medium and includes one or more instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute all or part of the steps of the method described in the embodiment of the present disclosure.
