[0059] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0060] Combined with Figures 1 to 18 As shown, the embodiments of the present disclosure provide a handle assembly for a refrigerator and a refrigerator.

[0061] Optionally, the refrigerator includes a main body, a handle 20, a detection device 50, a display element 40, a driving device 60, and a controller. The main body includes a door body 10, and the door body 10 is provided with a groove; the handle 20 moves between a hidden position located in the groove and a protruding position protruding from the groove; the detection device 50 is arranged on the refrigerator for detecting an opening signal; the display element 40 is arranged on the handle 20 or the door body 10; the driving device 60 is drivingly connected to the handle 20 for driving the handle 20 to move between the hidden position and the protruding position; the controller is connected to the detection device 50, the display element 40, and the driving device 60, and is used for controlling the display element 40 to work and controlling the driving device 60 to drive the handle 20 to move from the hidden position towards the protruding position when the detection device 50 detects an opening signal, where, Figure 2 is for the handle 20 being in the hidden position, Figure 5 is for the handle 20 being in the protruding position.

[0062] Optionally, the detection device 50 includes a radio frequency identification sensor, which can identify the running speed and direction of a movable object within a preset distance to judge the action of the user approaching the refrigerator. The detection device 50 can also be an infrared sensor, a ranging sensor, a camera, or other identification devices.

[0063] Optionally, set the preset distance of the radio frequency identification sensor to 2 meters. When the user enters the range within 2 meters of the freezer, the radio frequency identification sensor detects the door opening signal and transmits the signal to the controller. The controller controls the display element 40 to work and emits a prompt signal.

[0064] Optionally, the preset time of the radio frequency identification sensor can be set. For example, set the preset time for the radio frequency identification sensor to continuously detect to 3 seconds. When the user enters the range within 2 meters of the freezer, after the radio frequency identification sensor continuously detects the door opening signal for 3 seconds, the controller controls the driving device 60 to drive the handle 20 to move from the hidden position to the protruding position.

[0065] When the object moves beyond the preset distance, the motion signal of the object obtained by the radio frequency identification sensor disappears. The controller controls the display element 40 to stop working and controls the handle 20 to reset.

[0066] In this way, when the user enters the preset distance of the radio frequency identification sensor, the controller controls the display element 40 to emit a prompt signal to remind the user that the handle 20 has received the door opening instruction; after the radio frequency identification sensor continuously detects the door opening signal for the preset time, the controller controls the driving device 60 to drive the handle 20 to rotate so that the handle 20 helps to open the door body 10; when the user leaves the freezer and the radio frequency identification sensor detects that the door opening signal disappears, the controller controls the driving device 60 to drive the handle 20 to reset, improving the intelligence level of the handle 20 during the entire door opening process.

[0067] Optionally, as shown in combination with Figure 3 the freezer further includes a handle box 30 and a push rod assembly 70. The handle box 30 is arranged in the groove. The handle 20 is arranged in the handle box 30 and is movably connected to the handle box 30, and can move between a hidden position located in the handle box 30 and a protruding position protruding from the handle box 30 relative to the handle box 30. The push rod assembly 70 is arranged in the handle box 30 and can move between an extended position extending out of the handle box 30 and a retracted position retracting into the handle box 30. Figure 3 The push rod assembly 70 is in the extended position. The push rod assembly 70 cooperates with the handle 20. When the handle 20 moves relative to the handle box 30, it drives the push rod assembly 70 to move between the extended position and the retracted position. From the retracted position to the extended position, the push rod assembly 70 moves towards the cabinet body and abuts against the cabinet body to push the door body 10 away from the cabinet body to realize door opening assistance.

[0068] Opening the refrigerator door can be divided into two processes. The first process is that the detection device 50 recognizes the door opening signal and transmits the door opening signal to the controller. The controller controls the display element 40 to work, and the display element 40 issues a work prompt in response to the door opening signal. Then the controller controls the driving device 60 to drive the handle 20 from the hidden position to the hovering position, which is the initial stage of opening the handle 20. At this time, the handle 20 gradually protrudes from the handle box 30, the push rod assembly 70 is still in the retracted position, and the door body 10 is not opened; the second process is that the user turns the handle 20. The user needs to apply a force to the handle 20 to overcome the movement of the handle 20 relative to the handle box 30 and a force to drive the push rod assembly 70 to extend, so that the handle 20 moves from the hovering position to the protruding position. The push rod assembly 70 moves from the retracted position to the extended position under the drive of the handle 20. During the extension process, the push rod assembly 70 abuts against the cabinet body to push the door body 10 open.

[0069] Optionally, combined Figure 2 and Figure 3 As shown, the display element 40 includes a display light 41, which is disposed on the handle 20 or the door body 10. When the detection device 50 detects a door opening signal, the controller controls the display light 41 to light up.

[0070] Optionally, the display light 41 is a light emitting diode (LED). By setting the LED light, the user's door opening command is responded to, and the movement state of the handle 20 is prompted, thereby improving the degree of intelligence. In addition, it can also illuminate the user in a dark environment, indicate the position of the handle 20, and improve the user experience.

[0071] Optionally, the refrigerator further includes a mounting plate 43 and a light-transmitting plate 42 , the mounting plate 43 is disposed on the handle 20 or the door body 10 , the light-transmitting plate 42 is disposed on a side of the mounting plate 43 away from the door body 10 , and the display light 41 is disposed between the mounting plate 43 and the light-transmitting plate 42 .

[0072] The display lamp 41 is arranged between the mounting plate 43 and the light-transmitting plate 42, so as to enhance the protection of the display lamp 41. Moreover, by arranging the light-transmitting plate 42, it is convenient for the light of the display lamp 41 to be transmitted out.

[0073] Embodiment 1:

[0074] According to a first aspect of the first embodiment of the present disclosure, a handle assembly for a refrigerator is provided, wherein a display element 40 is disposed on the handle 20 .

[0075] Optionally, combined Figures 4 to 8As shown in the figure, the handle assembly includes a handle box 30, a rotating shaft 31, a handle 20, and a display element 40. The handle 20 is rotatably connected to the handle box 30 through the rotating shaft 31. The display element 40 is disposed on the handle 20 and electrically connected to the controller so that the controller controls the operation of the display element 40. The handle box 30 is provided with a first wire passing hole 37, and the handle 20 is provided with a second wire passing hole 21, and the second wire passing hole 21 is coaxially arranged with the rotating shaft 31. The connection line between the display element 40 and the controller sequentially passes through the second wire passing hole 21 and the first wire passing hole 37.

[0076] Optionally, the number of the rotating shafts 31 is two, and the two rotating shafts 31 are oppositely arranged. One of the two rotating shafts 31 is provided with a first wire passing hole 37, and the first wire passing hole 37 is coaxially arranged with the rotating shaft 31.

[0077] The handle 20 is rotatably connected to the handle box 30 through the rotating shaft 31 and can rotate around the rotating shaft 31 between a hidden position located in the handle box 30 and a protruding position protruding from the handle box 30. The second wire passing hole 21 is coaxially arranged with the rotating shaft 31, and the first wire passing hole 37 corresponds to the second wire passing hole 21. The connection line connected to the display element 40 sequentially passes through the second wire passing hole 21, the first wire passing hole 37, and is connected to the controller. In this way, the internal wiring in the handle box 30 can be reduced. When the handle 20 rotates around the rotating shaft 31, it can prevent the handle 20 from pulling the connection line between the display element 40 and the controller and avoid damage to the circuit.

[0078] Optionally, the first wire passing hole 37 is coaxially arranged with the second wire passing hole 21.

[0079] The first wire passing hole 37 is disposed on the side wall of the handle box 30, and the second wire passing hole 21 is disposed on the handle 20. The first wire passing hole 37 and the second wire passing hole 21 are coaxially corresponding. The line connecting the display element 40 passes out of the second wire passing hole 21 and penetrates into the first wire passing hole 37 and is connected to the controller. Compared with the misaligned arrangement of the first wire passing hole 37 and the second wire passing hole 21, the distance between the first wire passing hole 37 and the second wire passing hole 21 can be reduced, thereby reducing the total length of the connection line between the display element 40 and the controller, avoiding misaligned wiring of the circuit, reducing circuit entanglement, and optimizing the circuit layout.

[0080] Optionally, along the axis of the rotating shaft 31, the rotating shaft 31 and the second wire passing hole 21 are sequentially arranged.

[0081] By sequentially arranging the rotating shaft 31 and the second wire passing hole 21, and the rotating shaft 31 and the second wire passing hole 21 are located on the same axis, the connection line between the display element 40 and the controller can pass out along a straight line, avoiding circuit bending.

[0082] Optionally, at least a part of the side wall of the hole wall of the second wire threading hole 21 is inserted into the first wire threading hole 37 and can rotate relative to the first wire threading hole 37; alternatively, at least a part of the side wall of the hole wall of the first wire threading hole 37 is inserted into the second wire threading hole 21 and can rotate relative to the second wire threading hole 21.

[0083] In this way, the handle 20 can rotate relative to the buckle box 30 between the hidden position and the protruding position with at least a part of the side wall of the hole wall of the first wire threading hole 37 as the rotating shaft 31, or the handle 20 can rotate relative to the buckle box 30 between the hidden position and the protruding position with at least a part of the side wall of the hole wall of the second wire threading hole 21 as the rotating shaft 31.

[0084] In addition, at least a part of the side wall of the hole wall of the second wire threading hole 21 is inserted into the first wire threading hole 37, or at least a part of the side wall of the hole wall of the first wire threading hole 37 is inserted into the second wire threading hole 21, which can reduce the total length of the connection line between the display element 40 and the controller, and can also prevent part of the circuit from being exposed outside the first wire threading hole 37 and the second wire threading hole 21, playing a protective role for the circuit.

[0085] Optionally, in combination Figure 9 As shown, the handle 20 is provided with a rotating cavity 24, the rotating shaft 31 is inserted into the rotating cavity 24, and the second wire threading hole 21 is arranged on one side of the rotating cavity 24 and communicated with the rotating cavity 24.

[0086] The rotating shaft 31 is inserted into the rotating cavity 24 so that the handle 20 rotates between the hidden position and the protruding position around the rotating shaft 31. The second wire threading hole 21 is arranged on one side of the rotating cavity 24, and the connection line connecting the display element 40 and the controller enters the second wire threading hole 21 from the rotating cavity 24 and passes out of the second wire threading hole 21, thereby limiting the connection line in the rotating cavity 24 and preventing the connection line between the display element 40 and the controller from falling to other positions and causing pulling damage when the handle 20 moves.

[0087] Optionally, the side wall of the rotating cavity 24 is provided with a wire threading groove 27, and at least a part of the connection line connected to the display element 40 is arranged in the wire threading groove 27.

The rotating shaft 25 is arranged in the rotating cavity 24, and the damper 26 is located in the rotating cavity 24 and sleeved outside the rotating shaft 25; the damper 26 is arranged corresponding to the wire threading groove 27 to limit at least a part of the connection line connected to the display element 40.

[0089] Above the damper 26, a wire slot 27 is formed in the top wall of the rotation cavity 24 facing the direction of the damper 26. At least part of the wires connected to the display element 40 pass through the wire slot 27 and exit from the second wire passing hole 21. The damper 26 confines this part of the wires in the wire slot 27.

[0090] By providing the wire slot 27, at least part of the wires connected to the display element 40 are confined in the wire slot 27 and pass through the wire slot 27 and exit from the second wire passing hole 21 and the first wire passing hole 37 in sequence. In this way, the routing distance of this part of the wires can be reduced, and contact with other components can be avoided, preventing the wires inside the handle 20 from being pulled when the handle 20 rotates around the rotating shaft 31.

[0091] Optionally, as shown in Figure 9 and Figure 11 the damper 26 includes a first damper 261 and a second damper 262. The handle 20 is provided with a first limiting portion 100, and the first damper 261 is provided with a first limiting and cooperating portion 110. The first limiting portion 100 cooperates with the first limiting and cooperating portion 110 to fix the first damper 261 on the handle 20. The first damper 261 is disposed on the outer wall surface of the rotating shaft 25 and is in contact with the rotating shaft 25.

[0092] Optionally, as shown in Figure 4 and Figure 11 the second damper 262 is disposed on the outer wall surface of the first damper 261 and is in contact with the first damper 261. The buckle box 30 is provided with a second limiting portion 200, and the second damper 262 is provided with a second limiting and cooperating portion 210.

[0094] By providing the first damper 261 and the second damper 262, the handle 20 rotates more smoothly relative to the buckle box 30 between the hidden position and the protruding position.

[0095] Optionally, as shown in Figure 12 the outer surface of the handle 20 is provided with a mounting groove 28 for mounting the display element 40. The mounting groove 28 is communicated with the wire slot 27, and at least part of the wires connected to the display element 40 are disposed in the mounting groove 28.

[0096] By providing the mounting groove 28, part of the wires connected to the display element 40 are received in the mounting groove 28 of the handle 20.

[0097] Optionally, the display element 40 is provided on the outer surface of the handle 20. A third wire passing hole 23 is also provided on the outer surface of the handle 20, and the third wire passing hole 23 communicates with the second wire passing hole 21.

[0098] Optionally, the damper 26 is provided in the rotation cavity 24, and the wire groove 27 is provided between the third wire passing hole 23 and the damper 26.

[0099] The wiring mode of the wire connecting the controller and the display element 40 inside the handle 20 is as follows: The wire passes out from the end of the display element 40, passes through the installation groove 28, penetrates into the handle 20 through the third wire passing hole 23, then passes through the wire groove 27, passes out from the second wire passing hole 21, and then penetrates into the first wire passing hole 37 to be connected to the controller.

The wire connected to the display element 40 is located in the installation groove 28, passes through the second wire passing hole 22 into the handle box 30, and passes out of the handle box 30 through the first wire passing hole 38 and is connected to the controller, reducing the internal wire routing length of the handle box 30 and reducing wire pulling.

[0107] Optionally, in combination with Figure 15 As shown, a limiting portion 400 is provided on the bottom wall of the installation groove 28. The limiting portion 400 is located between the display element 40 and the second wire passing hole 22.

[0112] The first wire passing hole 38 is provided in the bottom wall of the installation cavity 34, the second wire passing hole 22 is provided in the bottom wall of the installation groove 28, and the handle 20 is provided in the installation cavity 34, which can reduce the distance between the first wire passing hole 38 and the second wire passing hole 22, thereby reducing the wire routing length of the wire between the display element 40 and the controller in the handle box 30.

[0113] Optionally, in combination with Figure 15 As shown, the handle 20 assembly for the refrigerator cabinet further includes a rotating shaft 31, and the handle 20 is rotatably connected to the handle box 30 through the rotating shaft 31; the handle 20 includes a first end portion 201 and a second end portion 202. When opening the door, the first end portion 201 protrudes outward, the second end portion 202 protrudes toward the handle box 30, and the second wire passing hole 22 is provided in the second end portion 202.

[0114] After the detection device 50 detects the door opening signal, the controller controls the driving device 60 to drive the handle 20 to rotate, so that the first end 201 rotates in the direction away from the handle box 30. The first end 201 protrudes outward from the handle box 30 and serves as a force-bearing end, so that the user can hold the first end 201 to rotate the handle 20. The second end 202 rotates toward the handle box 30 to cooperate with the push rod assembly 70, driving the push rod assembly 70 to move from the retracted position to the extended position. The push rod assembly 70 moves toward the cabinet and abuts against the cabinet to push the door body 10 out in the direction away from the cabinet to achieve door opening assistance.

[0115] Since the second end 202 rotates toward the handle box 30 when the handle 20 rotates, the second wire hole 22 is provided at the second end 202 to prevent the line from being pulled out of the handle box 30 when the handle 20 rotates, thereby preventing the line from being damaged.

[0116] Optionally, the handle assembly for the refrigerator further includes a rotating shaft 25; the handle is provided with a rotating cavity 24, and the rotating shaft 25 is provided in the rotating cavity 24; the distance between the second wire hole 22 and the rotating shaft 25 is smaller than the distance from the outer edge of the second end 202 away from the first end 201.

[0117] Optionally, the rotating shaft 31 is coaxially arranged with the rotating shaft 25 .

[0118] The handle 20 rotates relative to the handle box 30 with the rotation axis 31 as the axis. The closer to the axis where the rotation axis 31 is located, the smaller the rotation range. The distance between the second wire hole 22 and the rotation axis 25 is smaller than the distance to the outer edge of the second end 202 away from the first end 201, so that the second wire hole 22 is closer to the rotation axis 25, reducing the rotation range of the second wire hole 22, thereby reducing the pulling of the line between the first wire hole 38 and the second wire hole 22.

[0119] Optionally, the length of the first end 201 is greater than the length of the second end 202 , and the connection portion between the display element 40 and the controller is disposed at the first end 201 .

[0120] When the user turns the handle 20, the user needs to apply a force to the handle 20 to overcome the movement of the handle 20 relative to the handle box 30 and a force to drive the push rod assembly 70 to extend. The length of the first end 201 is greater than the length of the second end 202. According to the lever principle, it can save effort and reduce the force that the user needs to apply. When the handle 20 is turned, the first end 201 protrudes outward, and the second end 202 protrudes toward the handle box 30. The display element 40 is at least partially disposed at the first end 201, so that the user can see that the display element 40 is lit.

[0141] Optionally, the wire outlet groove 36 penetrates through the outer surface of the handle box 30.

[0142] The wire outlet groove 36 is arranged on the groove side wall of the fixing groove 35 facing away from the handle 20, so that the line connected to the display element 40 passes through the wire outlet groove 36 and is connected to the controller. The wire outlet groove 36 penetrates through the outer surface of the handle box 30, facilitating wire threading and avoiding the connection line between the display element 40 and the controller from running on the outer surface of the handle box 30 and being damaged by the foaming material.

[0143] According to the second aspect of Embodiment III of the present disclosure, a freezer is provided. The freezer includes a cabinet body and a door body 10; the door body 10 is movably provided on the cabinet body and has a groove; the handle 20 assembly for the freezer as described in any one of the above embodiments, and the buckle box 30 is arranged in the groove.

[0144] Optionally, as shown in Figure 4 the buckle box 30 is provided with a first installation groove 32; the detection device 50 includes a sensor, and the sensor is arranged in the first installation groove 32.

[0145] Optionally, the buckle box 30 is provided with a second installation groove 33; the driving device 60 includes a motor 61, and the motor 61 is arranged in the second installation groove 33.

[0146] The sensor and the motor 61 are respectively arranged in the first installation groove 32 and the second installation groove 33. In this way, the devices cooperatively connected with the handle 20 are modularly arranged in the buckle box 30, making the structure more compact and reducing the occupied space.

[0147] Optionally, as shown in Figure 14 the driving device 60 further includes a cam 62, the cam 62 is drivingly connected with the motor 61, and the motor 61 drives the cam 62 to rotate around its own rotation center; the handle 20 is provided with a baffle 203, and the baffle 203 is arranged at the second end 202 of the handle 20. The baffle 203 abuts against the outer contour of the cam 62, and the cam 62 drives the baffle 203 to move, so that the handle 20 moves from the hidden position to the protruding position.

[0148] Optionally, the freezer further includes a link assembly 80, the link assembly 80 is arranged between the handle 20 and the push rod assembly 70, and the handle 20 drives the push rod assembly 70 to move between the extended position and the retracted position through the link assembly 80.

[0149] When the handle 20 is in the hidden position, the outer contour corresponding to the minor axis of the cam 62 abuts against the baffle 203, that is Figure 14For the state of the cam 62 shown, the first process of opening the refrigerator door is as follows: The detection device 50 recognizes the door opening signal, the controller controls the display element 40 to light up, and the controller controls the motor 61 to start. The motor 61 drives the cam 62 to rotate around its own rotation center. The baffle 203 drives the second end 202 of the handle 20 to move towards the buckle box 30 as the cam 62 rotates, and the first end 201 moves towards the protruding position outside. When the outer contour corresponding to the major diameter of the cam 62 abuts against the baffle 203, the handle 20 is in the hovering position, and the second end 202 abuts against the link assembly 80. The second process of opening the refrigerator door is as follows: When the handle 20 is in the hovering position, a force is applied to the first end 201, and the handle 20 is further rotated in the direction away from the buckle box 30, so that the second end 202 pushes the link assembly 80 to move, so that the link assembly 80 drives the push rod assembly 70 to move towards the protruding position. The push rod assembly 70 abuts against the cabinet body to push the door body 10 away from the cabinet body to realize the door opening assistance.

[0150] By setting the motor 61 to drive the cam 62 to rotate, the handle 20 can move between the hidden position and the hovering position, and when the outer contour corresponding to the major diameter of the cam 62 abuts against the baffle 203, the handle 20 can be limited to the hovering position.

[0151] Optionally, in combination with Figure 3 As shown, the link assembly 80 includes a first link 81 and a second link 82. The first link 81 is movably arranged in the buckle box 30. The first link 81 includes a first side 811 and a second side 812, and the first side 811 cooperates with the handle 20; the second link 82 is movably arranged in the buckle box 30. The second link 82 includes a third side 821 and a fourth side 822, and the third side 821 abuts against the second side 812, and the push rod assembly 70 cooperates with the fourth side 822; when the handle 20 rotates towards the protruding position relative to the buckle box 30, it drives the first link 81 to move, and the first link 81 drives the second link 82 to move to drive the push rod assembly 70 to move towards the protruding position.

[0152] Optionally, the first link 81 is rotatably connected to the buckle box 30 through a first limiting shaft 83. The first side 811 and the second side 812 are respectively located on opposite sides of the first limiting shaft 83. In this way, when the handle 20 rotates and abuts against the first side 811, it drives the first side 811 to move downward (towards the bottom wall of the buckle box 30), and the second side 812 moves upward (away from the bottom wall of the buckle box 30).

[0153] Optionally, the second link 82 is rotatably connected to the buckle box 30 through a second limiting shaft 84. The third side 821 and the fourth side 822 are respectively located on opposite sides of the second limiting shaft 84. In this way, when the second side 812 drives the third side 821 to move upward, the fourth side 822 moves downward, thereby driving the push rod assembly 70 towards the cabinet body.

[0154] In this way, at the beginning, the handle 20 is in the hidden position. Then, when the detection device 50 recognizes the door-opening signal, the display lamp 41 lights up, and the motor 61 drives the cam 62 to rotate to drive the handle 20 to move from the hidden position to the hovering position. The user applies a force to the first end 201 and continues to rotate the handle 20 in the direction away from the handle box 30. The second end 202 abuts against the first link 81, and the force is sequentially transmitted to the push rod assembly 70 through the first link 81 and the second link 82, realizing the assisted door opening of the handle 20.

[0155] Optionally, the refrigerator also includes a first reset member 91. The first reset member 91 can be a torsion spring, and the torsion spring is sleeved on the rotating shaft 25. The rotating shaft 25 is located in the rotating cavity 24. The first reset member 91 is located between the handle 20 and the handle box 30. When the handle 20 moves from the hidden position towards the protruding position, the first reset member 91 undergoes elastic deformation. After the door body 10 is opened, the elastic force of the first reset member 91 due to elastic deformation is used to drive the handle 20 to return from the protruding position to the hidden position.

[0156] Optionally, the handle box 30 is provided with a third limiting portion 300. One end of the torsion spring abuts against the third limiting portion 300, and the other end rotates with the handle 20, so that during the rotation of the handle 20, the torsion spring undergoes elastic deformation and obtains an elastic force.

[0157] Optionally, as shown in Figure 18 the refrigerator also includes a second reset member 92. The second reset member 92 is supported between the second link 82 and the handle box 30. During the process of the handle 20 moving from the hidden position to the protruding position, the second reset member 92 undergoes elastic deformation. After the door body 10 is opened, the second reset member 92 drives the second link 82 to reset, so that the handle 20 is reset. The second reset member 92 can be a spring, one end of the spring is connected to the handle box 30, and the other end is connected to the second link 82.

[0158] Optionally, the controller is configured to: control the refrigerator, including: when the user is within the recognition range of the detection device 50, the controller determines a duration threshold according to the position where the user enters the recognition range and starts timing. When the cumulative timing duration is greater than or equal to the duration threshold, the controller controls the handle 20 to be in the hovering position.

[0159] In this way, based on the position where the user enters the recognition range, the timing scheme corresponding to the entry path is executed, reducing the influence of different paths of the user reaching the refrigerator on the hovering control of the handle, improving the accuracy of the hovering timing of the handle 20, and thus enhancing the user experience.

[0160] Optionally, the controller is configured to: determine a duration threshold according to the position where the user enters the recognition range, including: determining the current walking path of the user according to the position where the user enters the recognition range; and determining the duration threshold according to the current walking path. In this way, determining the duration threshold based on the user's walking path can make the timing more accurate, thereby improving the accuracy of the handle hovering timing.

[0161] Optionally, the controller is configured to: determine the current walking path of the user according to the position where the user enters the recognition range, including: obtaining the starting positions of all walking paths by the controller; and determining the walking path corresponding to the starting position closest to the position where the user enters the recognition range as the current walking path. In this way, the closer to the starting position of the path, the greater the possibility that the user will go to use the freezer from the path where the closest starting position is located. Therefore, the controller takes the walking path closest to the position where the user enters the recognition range as the current walking path.

[0162] Optionally, the controller is configured to: determine all walking paths of the user by the following method: determining the walking route of the user according to the current spatial information of the environment around the freezer. In this way, since the environmental information around the freezer includes information such as obstacles and free space, which determines which paths the user can take to reach the freezer, all walking paths of the user can be determined based on the environmental information around the freezer.

[0163] Optionally, the controller is configured to: determine the walking route of the user according to the current spatial information of the environment around the freezer, including: establishing a three-dimensional model according to the current spatial information by the controller; simulating and determining the walking route of the user in the three-dimensional model through a set algorithm; where the spatial information includes the size of the room where the freezer is located, the position of the freezer in the room, the size information of the items around the freezer, and / or the placement information of the items around the freezer. In this way, the controller can specifically use the collected spatial information to construct a three-dimensional model using three-dimensional modeling algorithms including surface reconstruction, voxelization, mesh generation, etc. After constructing the three-dimensional model, the controller can simulate and determine the walking route of the user in the three-dimensional model using path planning algorithms including the A* algorithm, Dijkstra algorithm, RRT (Rapidly-exploring Random Tree) algorithm, etc. And the controller can update the three-dimensional model and the walking route of the user in real time to reflect the dynamic changes of the environment and the actual walking situation of the user. For example, if the user encounters an obstacle during walking, the controller can adjust the walking route to avoid the obstacle.

[0164] Optionally, the controller is configured to: determine a duration threshold according to the current walking path, including: the controller obtains the duration required for the user to complete each walking path; the controller determines the duration corresponding to the current walking path as the duration threshold. In this way, by obtaining the duration required for the user to complete all the pre-stored paths, the duration required for the user to complete the current path can be determined, and thus the duration threshold required for the timing operation can be determined.

[0165] Optionally, the controller is configured to: determine the duration required for the user to complete each walking path according to the following method: the controller obtains the path length of each walking path and the walking speed of the user; the controller determines the ratio of each path length to the walking speed as the duration required for the user to complete each walking path. In this way, based on the user's speed and the path length, the duration required for the user to complete the path can be calculated, and thus the duration required for the user to complete each path can be obtained.

[0166] The effects that can be achieved by the embodiments of the present disclosure are as follows: when the user approaches the freezer and needs to open the door, the display element 40 lights up and the handle 20 rotates, timely feedbacking the movement state of the handle 20 to the user. The user rotates the handle 20 to use the handle 20 to assist in opening the door. In addition, the embodiments of the present disclosure provide three wiring methods between the display element 40 and the controller, optimizing the circuit layout and preventing the circuit from being pulled when the handle 20 rotates, resulting in circuit failures.
