[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] According to an embodiment of the present invention, a refrigerator structure is provided; please refer to [link / reference]. Figures 1 to 7 The device includes: a housing 1 having a storage cavity 11; a door 2 rotatably connected to the housing 1 to open or close the storage cavity 11; a transfer component 3 movably connected to the inner wall of the storage cavity 11, the transfer component 3 having a transfer section 31 for carrying items to be retrieved, the transfer section 31 being movably disposed; the transfer component 3 having a storage state inside the storage cavity 11 and a transfer state outside the storage cavity 11; and a lifting component 4 movably connected to the housing 1; wherein, when the transfer component 3 is in the transfer state, the door 2 opens the storage cavity 11, and the lifting component 4 is correspondingly disposed to the transfer component 3 to transfer the items to be retrieved onto the lifting component 4 via the transfer section 31.

[0033] Specifically, in the refrigerator structure of the present invention, the transfer component 3 is movable relative to the inner wall of the storage cavity 11. The transfer component 3 is provided with a transfer part 31 that is driven by a hydraulic device to extend and rotate. When the transfer component 3 moves out of the storage cavity 11, the item to be retrieved carried by the transfer part 31 on the transfer component 3 also moves out of the storage cavity 11. Items placed on the transfer part 31 can move left and right. When in storage mode, the transfer component 3 is stationary inside the storage cavity 11; when in transfer mode, the transfer component 3 is outside the storage cavity 11. A lifting component 4 is installed on one side of the refrigerator, which enables the vertical movement of the item to be retrieved. The transfer part 31 on the transfer component 3 and the lifting component 4 work together to enable the left and right movement and vertical movement of the item to be retrieved within the storage cavity 11, completing the transport of the item within the refrigerator. Since the item to be retrieved can be taken from the refrigerator without having to approach it, the user base is expanded, making it suitable for people with mobility impairments or those who do not wish to use their hands, thus broadening the refrigerator's application range. The refrigerator structure of the present invention solves the technical problem of inconvenience in taking out and retrieving items from the refrigerator in related technologies.

[0034] See Figure 2 In this embodiment of the refrigerator structure, the refrigerator structure also includes a transfer bracket 32, which is movably connected to the cabinet 1. The transfer part 31 includes a plurality of spaced-apart first transfer rods 311, which are rotatably connected to the transfer bracket 32. The first transfer rods 311 are composed of a plurality of circular rollers arranged horizontally at intervals. The plurality of horizontally arranged first transfer rods 311 can all rotate relative to the transfer bracket 32, so that the contact surface between the item to be retrieved and the transfer part 31 is formed by a plurality of parallel line contacts, thereby ensuring the flexibility and stability of the item to be retrieved during transportation.

[0035] See Figure 2 In this embodiment of the refrigerator structure, the refrigerator structure further includes: a first connecting rod 12, which is connected to the side wall of the cabinet 1; and a second connecting rod 13, which is inserted into the end of the first connecting rod 12 away from the side wall of the cabinet 1, and is movably arranged relative to the first connecting rod 12. The second connecting rod 13 is connected to the transfer bracket 32. In this way, the first connecting rod 12 is connected to the side wall of the cabinet 1, the second connecting rod 13 is inserted into the first connecting rod 12, and can move in and out at the other end of the first connecting rod 12; the second connecting rod 13 is also connected to the transfer bracket 32. By the extension and retraction of the second connecting rod 13 into and out of the first connecting rod 12, the transfer bracket 32 ​​is moved back and forth, thereby causing the items to be retrieved in the storage cavity 11 to move back and forth, so as to realize the removal or storage of items.

[0036] See Figure 1In the refrigerator structure of this embodiment, the storage cavity 11 is provided with: a shelf 14 connected to the cabinet 1; and a storage section 141, which is movably disposed and used to place items to be retrieved. When the transfer component 3 is in the transfer state, the items to be retrieved are transferred to the transfer component 31 through the storage section 141. When the items to be retrieved in the storage cavity 11 need to be transferred, the movement of the storage section 141 drives the items to be retrieved to the transfer component 31, thereby realizing the transfer of items from the storage cavity 11 to the transfer component 3.

[0037] See Figure 1 In the refrigerator structure of this embodiment, the storage section 141 includes a plurality of second transfer rods 1411 rotatably connected to the storage rack 14; the transfer section 31 is located below the second transfer rods 1411. The second transfer rods 1411 are composed of several circular rollers arranged horizontally at intervals. All of the horizontally arranged second transfer rods 1411 are rotatable relative to the storage rack 14, ensuring stable contact between the item to be retrieved and the storage section 141 while also enabling movement of the item. The transfer section 31 is located below the second transfer rods 1411. When the item to be retrieved moves close to the transfer section 31, gravity causes the item to slide onto the transfer section 31 for further transfer.

[0038] See Figure 3 and Figure 4 In the refrigerator structure of this embodiment, one side of the cabinet 1 has a first connecting sidewall 15, and the door 2 is rotatably connected to the first connecting sidewall 15. The transfer component 3 includes a first transfer component 34 and a second transfer component 35, with the first transfer component 34 located on the side of the second transfer component 35 away from the first connecting sidewall 15. The first transfer component 34 and the second transfer component 35 are provided and driven to work by corresponding hydraulic devices. If the item to be retrieved is on the left shelf 14, only the hydraulic device on the left is activated to drive the left first transfer component 34 to work. At the same time, the drive device for rotating the second transfer rod 1411 on the corresponding shelf 14, the air curtain system, and the automatic door opening and closing system are activated to control the refrigerator door 2 to be half-open. The angle m of the half-open refrigerator door is sufficient for the left first transfer component 34 to work. If the item to be retrieved is on the right shelf, the hydraulic devices on both sides are activated simultaneously to drive the first transfer component 34 and the second transfer component 35 to work. At the same time, the drive device for rotating the second transfer rod 1411 on the corresponding shelf 14, the air curtain system, and the automatic door opening and closing system are activated to control the refrigerator door 2 to be fully opened. The angle of the fully opened refrigerator door can meet the working requirements of the first transfer component 34 and the second transfer component 35.

[0039] See Figure 1In this embodiment of the refrigerator structure, the refrigerator structure further includes: a second connecting sidewall 16 disposed opposite to the first connecting sidewall 15, a storage cavity 11 disposed between the first connecting sidewall 15 and the second connecting sidewall 16; a lifting guide rail 5 disposed on the side of the second connecting sidewall 16 away from the first connecting sidewall 15, and a lifting component 4 movably connected to the lifting guide rail 5. The space between the first connecting sidewall 15 and the second connecting sidewall 16 forms the storage cavity 11. The transfer component 3 moves the item to be retrieved from the storage cavity 11 to the side near the second connecting sidewall 16. The lifting guide rail 5 is connected to the side of the second connecting sidewall 16, and the lifting component 4 can move on the lifting guide rail 5 to transfer the item to be retrieved from the transfer component 3 to the lifting component 4, and then the lifting guide rail 5 moves vertically. This arrangement realizes the function of transporting the item to be retrieved from a high place downwards.

[0040] See Figure 5 and Figure 6 In the refrigerator structure of this embodiment, the lifting guide rail 5 includes a first connecting plate 51, which is connected to a second connecting side wall 16. The first connecting plate 51 is equipped with a transmission rack 52 and a drive motor. The output shaft of the drive motor is driven by the transmission rack 52. The transmission rack 52 is connected to the lifting component 4. Driven by the drive motor, the transmission rack 52 drives the lifting component 4 to precisely determine the lifting height according to the position of the item to be retrieved. Then, the item is transferred to the lifting component 4 via a transfer part 31 that can move left and right. The lifting component 4 then moves vertically via the lifting guide rail 5.

[0041] See Figure 7In the refrigerator structure of this embodiment, the lifting guide rail 5 includes a second connecting plate 53, which is connected to a first connecting plate 51. The refrigerator structure also includes a connecting component 6, which is connected to a transmission rack 52 and a lifting component 4. The second connecting plate 53 has a guide groove 531 connected vertically. The lifting component 4 has a rotatably mounted guide wheel 41, which is movably mounted within the guide groove 531. The connection between the second connecting plate 53 and the first connecting plate 51 connects the refrigerator to the lifting guide rail 5 and the lifting component 4. The connecting component 6 is also connected to the transmission rack 52. This arrangement connects the transmission rack 52 of the lifting guide rail 5 and the lifting component 4, causing the transmission rack 52 to drive the lifting component 4 to move vertically. The second connecting plate 53 is provided with a guide groove 531. The guide wheel 41 of the lifting component 4 moves within the guide groove 531. The guide groove 531 acts as a moving guide rail, limiting the movement range of the guide wheel 41 and ensuring that the lifting component 4 can move along the preset track. The combination of the guide groove 531 and the guide wheel 41 of the lifting component 4 also provides support and ensures smooth operation.

[0042] See Figure 1 In the refrigerator structure of this embodiment, the storage compartment 11 includes a refrigerator compartment 111 and a freezer compartment 112. The refrigerator compartment 111 and the freezer compartment 112 are arranged at intervals along the moving direction of the lifting component 4. Transfer components 3 are respectively provided in the refrigerator compartment 111 and the freezer compartment 112. The storage compartment 11 is functionally divided, and different storage compartments 11 can be freely set to store different types of items. For example, the refrigerator compartment 111 and the freezer compartment 112 allow users to use the refrigerator flexibly according to their needs. Both the refrigerator compartment 111 and the freezer compartment 112 are equipped with transfer components 3, enabling intelligent transportation.

[0043] See Figure 1In the refrigerator structure of this embodiment, the storage cavity 11 includes: a placement cavity 113, located below the refrigerator cavity 111 and the freezer cavity 112; and a delivery cart 17. When the door 2 closes the storage cavity 11, the delivery cart 17 is placed inside the placement cavity 113. When the door 2 opens the storage cavity 11, the lifting component 4 transfers the item to be retrieved from the lifting component 4 to the delivery cart 17, and the delivery cart 17 transports the item to the target location. The lifting component 4 includes multiple rotatably mounted third transfer rods 42. A placement cavity 113 is located below the storage cavity 11, and the delivery cart 17 is placed inside the placement cavity 113. When an item needs to be retrieved, the door 2 opens the storage cavity 11, the delivery cart 17 moves out of the placement cavity 113, and the lifting component 4 transfers the item to be retrieved from the lifting component 4 to the delivery cart 17. After retrieval, the delivery cart 17 remains inside the placement cavity 113, and the door 2 closes. The lifting component 4 is equipped with a rotatable third transfer rod 42. The item to be retrieved is transferred from the storage cavity 11 to the first transfer rod 311 via the second transfer rod 1411, then transferred from the first transfer rod 311 to the third transfer rod 42, and finally transferred from the third transfer rod 42 to the delivery vehicle 17, thus completing the retrieval of the item.

[0044] This embodiment relates to a control method applicable to the above-described refrigerator structure. The control method includes: determining whether there is an item to be retrieved in the storage cavity 11 of the refrigerator structure; if so, driving the transfer component 3 to move out of the storage cavity 11 and transferring the item to be retrieved in the storage cavity 11 to the transfer component 3; driving the lifting component 4 to move to a position corresponding to the transfer component 3 and transferring the item to be retrieved in the storage cavity 11 to the lifting component 4; and driving the lifting component 4 to move and transfer the item to be retrieved to the target position.

[0045] The control method of this embodiment, the method for determining whether there is an item to be taken out in the storage cavity 11 of the refrigerator structure includes: determining whether there is an item to be taken out on the first transfer component 34 of the refrigerator structure;

[0046] If so, drive the door 2 to rotate by a first preset angle, so that the door 2 is in a half-open state, and drive the first transfer component 34 to rotate;

[0047] If not, drive the door 2 to rotate at a second preset angle, so that the door 2 is in a fully open state, and drive the first transfer component 34 and the second transfer component 35 of the refrigerator structure to rotate simultaneously;

[0048] The first preset angle is smaller than the second preset angle.

[0049] In an embodiment of the present invention, a transfer component 3 and a lifting component 4 are added to a single-door refrigerator with a left-side opening to realize the refrigerator's intelligent delivery function and control method. The refrigerator has three layers, namely a refrigeration compartment 111, a freezer compartment 112, and a placement compartment 113 for the storage and charging area of ​​the intelligent delivery vehicle 17.

[0050] First, the shelves of the traditional refrigerator are replaced with storage racks 14 consisting of a storage section 141 with a rotating roller (second transfer rod 1411). The second transfer rod 1411 is driven by a motor and belt to provide a conveying function, allowing items placed on it to move back and forth. Different storage racks 14 can be freely set to store different types of items, which can be updated via a mobile app, such as medicines and beverages. Below each storage rack 14 are two symmetrically arranged transfer components 3 with first transfer rods 311, driven by a hydraulic device for retraction and extension, allowing items placed on them to move left and right. A lifting guide rail 5, driven by a motor, gears, and a transmission rack 52, is installed on the left side of the refrigerator. A foldable lifting component 4 is fixed to the transmission rack 52 via a connecting component 6, thus enabling vertical movement of items under the drive of this lifting guide rail 5. The items inside the refrigerator can be moved forward and backward, left and right, and vertically by the second transfer rod 1411 on the shelf 14, the first transfer rod 311 on the transfer component 3, and the lifting component 4, thus completing the transport of items within the refrigerator. After the lifting guide rail 5 descends to a certain height, the items on the lifting component 4 are transferred to the delivery vehicle 17, and the delivery vehicle 17 completes the delivery task according to the prescribed route.

[0051] Figure 8 This is a schematic diagram of a control system for a refrigerator with intelligent delivery function. In addition to the normal refrigeration system, the refrigerator adds an air curtain system and an automatic door opening and closing system. When the refrigerator receives an instruction to take out an item, the refrigerator door and air curtain system automatically open. The air curtain acts as a protective barrier to prevent the loss of cold air inside the compartment during the door opening process. The opening angle can be controlled according to the usage of the transfer component 3.

[0052] When a user issues a command to retrieve an item via mobile phone or voice, the refrigerator first checks the inventory of the requested item. If no item is found, a restocking alert is issued. If the refrigerator detects the corresponding inventory, its smart delivery mode is activated. The refrigerator's control program first determines the location of the item on shelf 14. The operating mode differs depending on whether the item is on the left or right shelf. If the item is on the left shelf, only the hydraulic device on the left side is activated to drive the left-side transfer component 3. Simultaneously, the drive device of the second transfer rod 1411 of the corresponding shelf, the air curtain system, and the automatic door opening and closing system are activated to control the refrigerator door 2 to be half-open. The angle m of the half-open door is sufficient to allow the left-side transfer component 3 to operate. Figure 3As shown. When the transfer component 3 detects an item, the drive device of the second transfer rod 1411 at the shelf 14 stops working while the drive device of the first transfer rod 311 of the transfer component 3 starts. If the item to be retrieved is on the right shelf, the hydraulic devices on both sides are activated simultaneously to drive the transfer components 3 on both sides, and the drive devices of the second transfer rod 1411 at the corresponding shelf 14, the air curtain system, and the automatic door opening and closing system are activated to control the refrigerator door 2 to open fully. The angle of the fully opened refrigerator door is sufficient to allow the transfer components 3 on both sides to work. Figure 4 As shown. When the transfer component 3 detects an item, the drive mechanism of the second transfer rod 1411 of the shelf 14 stops working and simultaneously starts the drive mechanism of the first transfer rod 311 of the transfer component 3.

[0053] The lifting guide rail 5 precisely determines the lifting height of the lifting component 4 based on the position of the item on the shelf 14, driving the lifting component 4 to move vertically. The lifting component 4 is equipped with guide wheels 41. The lifting guide rail 5 and guide wheels 41 work together to provide support and smooth movement. When the lifting component 4 detects the presence of an item, it begins to descend. During the descent of the lifting component 4, the drive device of the first transfer rod 311 at the transfer component 3 stops working, and the hydraulic device drives the transfer component 3 to retract to the default position. The automatic door opening and closing system controls the refrigerator door 2 to close. When the refrigerator door 2 is completely closed, the air curtain system stops working. After the lifting component 4 descends to the delivery vehicle 17, it transfers the items on it to the delivery vehicle 17, which then delivers them according to the prescribed route. Subsequently, the lifting guide rail 5 drives the lifting component 4 to rise to the default position and folds it up, awaiting the next delivery task. After the delivery task is completed, it returns to the storage and charging area under the refrigerator in the delivery vehicle 17 for charging.
