Ice can then be removed from the refrigerator door, achieving optimal height. To further reduce usable space, the inventors of this application considered transporting ice through both the refrigerator and freezer doors. However, achieving a sealed door transport duct presents a pressing technical challenge. Summary of the Invention

During the movement of the movable channel toward the direction of extending out of the ice transport opening, the first matching portion contacts and pushes the second matching portion to move in the direction away from the ice transport opening, and drives the sealing member to move away from the ice transport opening; a reset member is arranged on the sealing member, and the reset member can drive the sealing member to move toward the ice transport opening to cover the ice transport opening.

[0005] According to one embodiment of the present application, the first direction is parallel to the extension direction of the ice transport channel, the first mating portion has a first contact portion on a side facing the ice transport port, and the second mating portion has a second contact portion on a side facing away from the sealing member, and at least one of the first contact portion and the second contact portion is inclined relative to a radial cross-section of the movable channel, thereby decomposing a thrust of the first mating portion on the second mating portion into a force component along the second direction.

[0006] According to an embodiment of the present application, the first contact portion is an inclined surface arranged obliquely relative to a radial cross-section of the movable channel, and the first contact portion is inclined toward a moving direction of the seal away from the ice transport port, and the second contact portion is an inclined surface arranged obliquely relative to a radial cross-section of the movable channel, and the second contact portion is inclined toward a moving direction of the seal close to the ice transport port, and when the movable channel is moved to be retracted into the door body and the seal is moved to cover the ice transport port, the projections of the first contact portion and the second contact portion in the first direction at least partially overlap.

[0007] According to one embodiment of the present application, the reset member includes: a reset elastic member, which is arranged on a side of the seal away from the ice transport port, and in the process of the first matching part pushing the seal to move away from the ice transport port, the reset elastic member is compressed to store energy, and in the process of the movable channel being retracted into the door body, the reset elastic member restores its deformation and pushes the seal to move toward the ice transport port; a sliding rod, which is passed through the reset elastic member, and the end of the sliding rod away from the seal is fixed relative to the reset elastic member, and the end of the sliding rod close to the seal is passed through the seal.

[0008] According to one embodiment of the present application, the first driving member includes: a first rack, which is arranged on the outside of the movable channel along the first direction; a first gear, which is rotatably arranged in the door body, and the first gear is engaged with the first rack; a driving member, and the output end of the driving member is connected to the first gear for driving the first gear to rotate.

[0009] According to one embodiment of the present application, the door body assembly includes: a bottom plate, which is arranged at the end of the door body having the ice transport port, and the bottom plate is provided with a bottom plate opening corresponding to the ice transport port; a cover plate, which is covered on the bottom plate, and the cover plate and the bottom plate are surrounded to form a first space, the sealing member is movably arranged in the first space along the second direction, and the cover plate is provided with a cover plate opening corresponding to the bottom plate opening; a shell plate, which is arranged at one end of the cover plate, and a second space is formed in the shell plate, the second space is connected to the cover plate opening, the first matching portion is movably arranged in the second space along the first direction, and the first space is located on one side of the second space.

[0010] According to one embodiment of the present application, sliding grooves extending along the second direction are formed on the opposite side walls of the cover plate, and the sealing member includes: a sealing body for movably covering the ice transport port; a sliding seat, which is arranged on both sides of the sealing body facing the sliding groove, and the sliding seat is movably arranged in the sliding groove.

[0011] According to one embodiment of the present application, the sealing member further includes a guide wheel, and the guide wheel is rotatably disposed on the sliding seat.

[0012] According to one embodiment of the present application, a limit groove arranged along the first direction is formed in the shell plate, and a limit block is provided on the outside of the movable channel.

[0014] The present application has the beneficial effect of providing a movable channel and a seal. When ice is not needed, the movable channel retracts into the door body, and the seal moves to cover the ice delivery opening, sealing the movable channel and the ice delivery passage. This prevents debris from entering through the exposed ice delivery opening, achieving both anti-fouling effects and preventing partial cooling loss. When ice is needed, the movable channel, driven by the first driving member, moves in a first direction until it extends out of the ice delivery opening. At this time, the first and second mating members cooperate to drive the seal in a second direction until it moves away from the ice delivery opening, thereby reducing or filling the gap with the ice transfer passage on the other door body. Ice cubes are no longer directly exposed to the outside world, preventing ice contamination and ice jams, and ensuring smooth ice passage. When ice is finally taken, the movable channel retracts in the first direction into the door body, and the seal, driven by the reset member, moves in a second direction until it covers the ice delivery opening, preventing debris from the outside world from entering the ice-making assembly through the ice delivery opening and causing ice contamination.

[0037] One embodiment of the present application provides a refrigeration device 10. The refrigeration device 10 includes a housing 11, a first refrigeration compartment 12, a second refrigeration compartment 13, a first door 14, a second door 15, an ice-making assembly 200, an ice-removing assembly 300, and an ice-moving device 100. The first refrigeration compartment 12 and the second refrigeration compartment 13 are formed in the housing 11 and have an opening on one side. The first door 14 is used to open and close the first refrigeration compartment 12, and the second door 15 is used to open and close the second refrigeration compartment 13. The second refrigeration compartment 13 is located above the first refrigeration compartment 12. The ice-making assembly 200 is disposed in the first refrigeration compartment 12. The ice-removing assembly 300 is disposed on the second door 15. The ice-moving device 100 includes an ice-moving channel 120 and an ice-moving assembly 101. The ice-moving assembly 101 is disposed in the first refrigeration compartment 12. The ice-moving channel 120 provides a path for ice cubes to move from the first refrigeration compartment 12 to the second door 15. The ice-moving assembly 101 is connected to the ice-making assembly 200 and is used to drive the ice cubes made by the ice-making assembly 200 to be moved out of the ice-moving channel 120. Among them, the first refrigeration compartment 12 is a freezer compartment, and the second refrigeration compartment 13 is a refrigerator compartment. The ice-moving device 100 can transport the ice cubes in the first refrigeration compartment 12 to the ice-taking assembly 300 located above the second refrigeration compartment 13, thereby facilitating ice taking by users and improving user experience. In addition, the ice-making assembly 200 is arranged in the first refrigeration compartment 12 and can share a cold source with the first refrigeration compartment 12. There is no need to separately set up an evaporator required for ice making because the ice-making assembly 200 is arranged in the second refrigeration compartment 13, thereby saving costs and the space occupied in the second refrigeration compartment 13 and improving the volume ratio of the second refrigeration compartment 13. The refrigeration equipment 10 of the present application not only improves the efficiency of ice taking, but also solves the problems of inconvenience in ice taking by users and space occupation in the second refrigeration compartment 13.

[0038] In order to further reduce the space occupied by the refrigeration compartment, the ice removal channel 120 can be provided in the first door body 14 and the second door body 15. Specifically, the ice removal channel 120 includes a first sub-channel 123 and a second sub-channel 124. The first sub-channel 123 is provided in the first door body 14 and communicates with the ice removal assembly 101. The second sub-channel 124 is provided in the second door body 15 and communicates with the ice removal assembly 300.

[0039] However, due to the gap between the first door 14 and the second door 15, the first sub-channel 123 and the second sub-channel 124 are exposed at their adjacent ends, which may cause ice blockage, ingress of debris, and loss of cooling capacity. Figures 3 to 6 , Figure 3 This is a schematic diagram of the overall structure of an embodiment of a door assembly of the present application; Figure 4 This is a schematic diagram of a state in which a sealing member of an embodiment of a door assembly of the present application covers an ice delivery port; Figure 5This is a schematic diagram of a state in which a sealing member of an embodiment of a door assembly of the present application is separated from an ice delivery port; Figure 6 This is a schematic diagram of a state in which a movable channel of an embodiment of a door assembly of the present application extends out of an ice transport opening.

[0040] In order to solve the above problems, an embodiment of the present application provides a door assembly 500. The door assembly 500 includes a door body 510, an ice transport channel 520, a movable channel 540, a first driving member 555, a sealing member 530, a first matching portion 5524, a second matching portion 5525 and a reset member 162. Among them, one end of the door body 510 has an ice transport opening 511. The ice transport channel 520 is arranged in the door body 510, and the ice transport channel 520 extends toward the ice transport opening 511. The movable channel 540 is movably arranged in the ice transport channel 520 along the first direction A and is connected to the ice transport channel 520. The movable channel 540 can be moved to extend out of the ice transport opening 511, or moved to be retracted into the door body 510. The first driving member 555 is arranged in the door body 510, and is used to drive the movable channel 540 to move back and forth along the first direction A. The seal 530 is movably mounted on the door body 510 along a second direction B. The seal 530 can be moved to cover the ice delivery opening 511 or to separate from the ice delivery opening 511. The second direction B intersects the first direction A. The first mating portion 5524 is disposed outside the movable channel 540, and the second mating portion 5525 is disposed on the side of the seal 530 facing away from the ice delivery opening 511. As the movable channel 540 moves toward the ice delivery opening 511, the first mating portion 5524 contacts and pushes the second mating portion 5525 away from the ice delivery opening 511, thereby moving the seal 530 away from the ice delivery opening 511. A reset member 162 is mounted on the seal 530. The reset member 162 can drive the seal 530 toward the ice delivery opening 511 until it covers the ice delivery opening 511.

[0041] As can be seen from the above structure, movable channel 540 and seal 530 are provided. When ice is not needed, movable channel 540 retracts into door body 510, and seal 530 moves to cover ice delivery opening 511, sealing movable channel 540 and ice delivery passage 520. This prevents debris from entering through the exposed ice delivery opening 511, thus achieving a contamination-proof effect and preventing some cooling loss. When ice is needed, movable channel 540, driven by first drive member 555, moves in a first direction A until it extends out of ice delivery opening 511. At this time, first engaging portion 5524 and second engaging portion 5525 cooperate to drive seal 530 in a second direction B until it moves away from ice delivery opening 511, thereby reducing or filling the gap with ice transfer passage 120 on the other side of door body 510. Ice is no longer directly exposed to the outside world, thus preventing ice contamination and ice jams, and ensuring smooth ice passage. When ice is taken out, the movable channel 540 moves along the first direction A under the drive of the first driving member 555 until it is retracted into the door body 510, and the sealing member 530 moves along the second direction B under the drive of the reset member 162 until it covers the ice delivery port 511, thereby preventing debris in the external space from entering the ice making assembly 200 through the ice delivery port 511 and causing ice contamination.

[0042] It should be noted that the door body 510 in the door body assembly 500 of the embodiment of the present application can be the first door body 14 or the second door body 15, or can even be applicable to both the first door body 14 and the second door body 15. When the door body 510 in the door body assembly 500 of the embodiment of the present application is the first door body 14, the ice transport channel 520 is the first sub-channel 123, which is used to communicate with the ice moving assembly 101, and the ice transport port 511 is located at the top of the first door body 14. At this time, since the direction of movement of ice cubes is from the ice transport channel 520 to the movable channel 540, in order to prevent ice cubes from colliding with the end of the movable channel 540 during transportation, the movable channel 540 is sleeved on the outside of the ice transport channel 520 and movably connected to the ice transport channel 520. The end surface of the movable channel 540 does not form a step surface in the ice transport channel 520, allowing ice cubes to pass smoothly. Of course, when the door body 510 in the door body assembly 500 of the embodiment of the present application is the second door body 15, the ice transport passage 520 is the second sub-passage 124, which is used to communicate with the ice removal assembly 300, and the ice transport opening 511 is located at the bottom of the second door body 15. In this case, since the direction of movement of ice cubes is from the movable passage 540 to the ice transport passage 520, to avoid collision with the end of the ice transport passage 520 during transportation, the movable passage 540 is provided inside the ice transport passage 520 and is movably connected to the ice transport passage 520. The end surface of the ice transport passage 520 does not form a step surface in the movable passage 540, allowing ice cubes to pass smoothly.

[0043] In one embodiment of the present application, the first direction A is parallel to the extension direction of the ice transport channel 520. The first mating portion 5524 has a first contact portion 5526 on the side that engages with the ice transport port 511, and the second mating portion 5525 has a second contact portion 5527 on the side facing away from the seal 530. At least one of the first contact portion 5526 and the second contact portion 5527 is inclined relative to the radial cross-section of the movable channel 540, thereby decomposing the thrust of the first mating portion 5524 on the second mating portion 5525 into a force component along the second direction B.

[0044] Specifically, when the first direction A is parallel to the extension direction of the ice transport channel 520, at least one of the first contact portion 5526 and the second contact portion 5527 is inclined relative to the radial cross-section of the movable channel 540. The thrust of the first matching portion 5524 on the second matching portion 5525 can be decomposed into a component force along the second direction B. Therefore, the movement of the first matching portion 5524 along the first direction A can drive the second matching portion 5525 to move along the second direction B, so that the seal 530 is separated from the ice transport port 511, and the movable channel 540 is extended out of the ice transport port 511. In this case, there is no need to set up an additional driving structure to drive the seal 530 to move along the second direction B. Fewer power elements are required, so its structure is simpler, which can effectively save space in the door body 510, thereby improving the user experience.

[0045] Furthermore, the first contact portion 5526 is an inclined surface disposed obliquely relative to the radial cross-section of the movable passage 540, and is inclined toward the direction of movement of the seal 530 away from the ice delivery port 511. The second contact portion 5527 is an inclined surface disposed obliquely relative to the radial cross-section of the movable passage 540, and is inclined toward the direction of movement of the seal 530 toward the ice delivery port 511. When the movable passage 540 is retracted into the door body 510 and the seal 530 is movable to cover the ice delivery port 511, the projections of the first contact portion 5526 and the second contact portion 5527 in the first direction A at least partially overlap. Specifically, when the movable channel 540 extends into the door body 510, the first contact portion 5526 contacts the second contact portion 5527. The force exerted by the first contact portion 5526 on the second contact portion 5527 drives the second contact portion 5527 to move in the second direction B, thereby moving the seal 530 away from the ice delivery opening 511 and extending the movable channel 540 out of the ice delivery opening 511. When the movable channel 540 retracts into the door body 510, the return member 162 drives the second contact portion 5527 in the second direction B until the seal 530 covers the ice delivery opening 511. The force exerted by the first contact portion 5526 on the second contact portion 5527 enables the movable channel 540 to extend out of the ice delivery opening 511 in the first direction A and the seal 530 to disengage from the ice delivery opening 511. This eliminates the need for multiple drive mechanisms to drive the seal 530 in the second direction B, resulting in a simpler overall structure and less space occupied within the door body, effectively improving user experience.

[0046] At the same time, the seal 530 only moves along one side, and the side of the movable channel 540 where the seal 530 is not set is smaller, which can effectively match the spatial structure of the door body 510. For example, when the ice transport channel 520 and the movable channel 540 need to be set close to the side of the rotating axis of the door body 510, the side of the movable channel 540 where the seal 530 is not set is smaller, and can be set relatively closer to the rotating axis.

[0047] In one embodiment of the present application, the reset member 162 includes a reset elastic member 1621 and a sliding rod 1622. The reset elastic member 1621 is arranged on the side of the sealing member 530 away from the ice delivery port 511. In the process of the first matching portion 5524 pushing the sealing member 530 to move away from the ice delivery port 511, the reset elastic member 1621 is compressed and stores energy. In the process of the movable channel 540 being retracted into the door body 510, the reset elastic member 1621 recovers its deformation and pushes the sealing member 530 to move toward the ice delivery port 511. The sliding rod 1622 is passed through the reset elastic member 1621. The end of the sliding rod 1622 away from the sealing member 530 is fixed relative to the reset elastic member 1621. The end of the sliding rod 1622 close to the sealing member 530 is passed through the sealing member 530. Specifically, when the first engaging portion 5524 pushes the second engaging portion 5525 to move in the second direction B until the seal 530 is separated from the ice delivery port 511, the return elastic member 1621 is compressed by the seal 530 to store energy. At this time, as the seal 530 moves away from the ice delivery port 511, the sliding rod 1622 is disposed within the seal 530 to prevent the return elastic member 1621 from deflecting during compression, which could result in a failure in the return elastic member 1621 to store energy. Furthermore, when the first driving member 555 drives the first engaging portion 5524 to move in the first direction A until the movable channel 540 is retracted into the door body 510, the return elastic member 1621 recovers its deformation, thereby imparting force to the second engaging portion 5525 in the second direction B, thereby pushing the second engaging portion 5525 in the second direction B until the seal 530 covers the ice delivery port 511. At this time, the distance that the sliding rod 1622 penetrates into the sealing member 530 becomes shorter and shorter. However, after the sealing member 530 completely covers the ice delivery port 511 and stops moving, the end of the sliding rod 1622 closest to the sealing member 530 is still penetrated into the sealing member 530, that is, the sliding rod 1622 does not completely escape from the sealing member 530. Therefore, when the sealing member 530 is moving, the sliding rod 1622 can always penetrate into the sealing member 530, thereby preventing the sliding rod 1622 from abutting against the sealing member 530, thereby preventing the sliding rod 1622 from being unable to penetrate the sealing member 530 and causing the reset elastic member 1621 to fail to store energy.

[0048] It should be noted that the reset elastic member 1621 may be a spring, a spring, or a torsion spring, which is not limited here.

[0049] Furthermore, the first driving member 555 includes a first rack 3321, a first gear 5551 and a driving member (not shown in the figure). Among them, the first rack 3321 is arranged outside the movable channel 540 along the first direction A. The first gear 5551 is rotatably arranged in the door body 510, and the first gear 5551 is engaged with the first rack 3321. The output end of the driving member is connected to the first gear 5551, which is used to drive the first gear 5551 to rotate. By driving the first gear 5551 to rotate forward and backward through the driving member, the first rack 3321 can be driven to move back and forth in the first direction A, thereby driving the movable channel 540 to move to extend out of the ice delivery port 511 or retract into the door body 510. In addition, the first driving member 555 has a relatively simple structure and can effectively save space in the door body 510.

[0050] In one embodiment of the present application, the door assembly 500 includes a bottom plate 553, a cover plate 5513, and a shell plate 556. The bottom plate 553 is arranged at the end of the door body 510 having the ice delivery port 511. The bottom plate 553 is provided with a bottom plate opening 5531 corresponding to the ice delivery port 511. The cover plate 5513 is covered on the bottom plate 553. The cover plate 5513 and the bottom plate 553 are surrounded to form a first space. The sealing member 530 is movably arranged in the first space along the second direction B. The cover plate 5513 is provided with a cover plate opening 5514 corresponding to the opening of the bottom plate 553. The shell plate 556 is arranged at one end of the cover plate 5513. A second space is formed in the shell plate 556, and the second space is connected to the cover plate opening 5514. The first matching portion 5524 is movably arranged in the second space along the first direction A, and the first space is located on one side of the second space. The cover plate opening 5514 is arranged corresponding to the bottom plate opening 5531, and the second space is connected to the cover plate opening 5514, which can facilitate the movement of the first mating portion 5524 and the movable channel 540 along the first direction A. The first space formed by the cover plate 5513 and the bottom plate 553 can prevent the seal 530 from moving in other directions, thereby limiting the movement of the seal 530 in the second direction B. The second space formed within the shell plate 556 can prevent the first mating portion 5524 from moving in other directions, thereby limiting the movement of the first mating portion 5524 along the first direction A.

[0051] It should be noted that, in this embodiment, the bottom plate 553 can be a structure integrally formed with the door body 510, that is, it is composed of the end plate on one side of the door body 510, or the bottom plate 553 can also be separately installed on the inner wall of the end plate of the door body 510, which is not limited here.

[0052] Furthermore, sliding grooves 5515 extending along the second direction B are formed on opposite side walls of the cover plate 5513. The seal 530 includes a sealing body 531 and a sliding seat 532. The sealing body 531 is configured to flexibly cover the ice delivery port 511. The sliding seats 532 are disposed on either side of the sealing body 531 facing the sliding grooves 5515. The sliding seats 532 are movably disposed within the sliding grooves 5515. The provision of the sliding grooves 5515 serves to limit the movement of the sliding seat 532 along the second direction B, preventing the sliding seat 532 from deviating and causing the seal 530 to be unable to move along the second direction B.

[0053] To further reduce friction between the sliding seat 532 and the sliding groove 5515, in some embodiments, the seal 530 further includes a guide wheel 557. The guide wheel 557 is rotatably mounted on the sliding seat 532. This reduces the friction between the sliding seat 532 and the sliding groove 5515 from sliding friction to rolling friction, resulting in a lower friction. This reduces friction and makes the sliding between the sliding seat 532 and the sliding groove 5515 smoother and more effortless. Furthermore, the sliding between the seal 530 and the cover plate 5513 is also smoother.

[0054] To ensure that the movable channel 540 moves into position, in some embodiments, a retaining groove (not shown) is formed in the shell 556 along a first direction A. A retaining block (not shown) is disposed outside the movable channel 540, which slides along the retaining groove. When the movable channel 540 moves to a first position extending beyond the ice delivery opening 511, the retaining block is located at one end of the retaining groove. When the movable channel 540 moves to a second position retracted within the door body 510, the retaining block is located at the other end of the retaining groove. Specifically, when the retaining block abuts the end of the retaining groove near the sealing member 530, the movable channel 540 has been extended beyond the ice delivery opening 511, and movement ceases. When the retaining block abuts the end of the retaining groove facing away from the sealing member 530, the movable channel 540 has been fully retracted within the door body 510, and movement ceases. The limit block slides along the limit groove. On the one hand, the limit groove can limit the limit block to a certain extent, thereby preventing the movable channel 540 from rotating; on the other hand, the limit block can also limit the movable position of the movable channel 540 to a certain extent.

[0055] The above embodiment provides a specific implementation of the sealing member 530 and the corresponding driving structure. In the above embodiment, the first matching portion 5524, the second matching portion 5525 and the reset member 162 can realize the asynchronous movement of the movable channel 540 and the sealing member 530. The sealing member 530 only moves along one side, and the space occupied on the other side of the movable channel 540 is small, thereby effectively matching the spatial structure of the door body 510. Please continue to refer to Figures 8 to 10 , Figure 8This is a schematic diagram of another embodiment of the door assembly of the present application, in which a sealing member covers the ice delivery port; Figure 9 This is a schematic diagram of another embodiment of the door assembly of the present application, in which the sealing member is separated from the ice delivery port; Figure 10 This is a schematic diagram of another embodiment of the door assembly of the present application with the movable channel extending out of the ice transport opening.

[0056] Another embodiment of the present application provides a sealing member 530, in which two sealing members 530 are provided. The two sealing members 530 are relatively movable along the second direction B and are arranged on the second door body 15. The two sealing members 530 can move toward each other to cover the ice transport opening 511, or can move away from the ice transport opening 511. Specifically, when the first driving member 555 drives the movable channel 540 to move along the first direction A to extend out of the ice transport opening 511, the sealing members 530 move away from the ice transport opening 511 along the second direction B. When the first driving member 555 drives the movable channel 540 to move along the second direction B to retract into the door body 510, the sealing members 530 move toward each other along the second direction B to cover the ice transport opening 511. In this case, this structure can effectively reduce the movement stroke of the sealing member 530, thereby effectively increasing the movement reliability of the structure and improving the efficiency of the sealing member 530 moving to cover and move away from the ice transport opening 511.

[0057] As can be seen from the above structure, the movable channel 540 and two sealing members 530 are provided. When ice is not needed, the movable channel 540 retracts into the door body 510, and the two sealing members 530 move toward each other to cover the ice delivery opening 511, thereby sealing the movable channel 540 and the ice delivery passage 520. This prevents debris from entering through the exposed ice delivery opening 511, thereby achieving a contamination-proof effect and preventing some cooling loss. When ice is needed, the movable channel 540, driven by the first driving member 555, moves in a first direction A until it extends out of the ice delivery opening 511. At this time, the first engaging portion 5524 and the second engaging portion 5525 cooperate to drive the sealing member 530 in a second direction B until it moves away from the ice delivery opening 511. This reduces or fills the gap with the ice transfer passage 120 on the other door body 510, eliminating the need for direct exposure of ice cubes to the outside world, preventing ice contamination and ice jams, and ensuring smooth ice passage. When ice is taken out, the movable channel 540 moves along the first direction A under the drive of the first driving member 555 until it is retracted into the door body 510, and the sealing member 530 moves toward each other along the second direction B under the drive of the reset member 162 until it covers the ice delivery port 511, thereby preventing debris in the external space from entering the ice making assembly 200 through the ice delivery port 511 and causing ice contamination.

[0058] Furthermore, two second mating portions 5525 are provided. Each second mating portion 5525 is correspondingly provided on the side of the sealing member 530 facing away from the ice transport opening 511. During the process of the movable channel 540 extending out of the ice transport opening 511, the first mating portion 5524 contacts and pushes the two second mating portions 5525 to move away from each other, and drives the two sealing members 530 to move away from each other until they are separated from the ice transport opening 511. Specifically, during the process of the first driving member 555 driving the movable channel 540 to extend out of the ice transport opening 511, the first mating portion 5524 contacts and pushes the two second mating portions 5525 to move away from each other, and the two second mating portions 5525 moving away from each other can drive the two sealing members 530 to move away from each other. At this time, the movable channel 540 can smoothly extend out of the ice transport opening 511. When the first driving member 555 drives the movable channel 540 to retract into the door body 510, the first driving member 555 drives the movable channel 540 to move along the first direction A until the movable channel 540 is retracted into the door body 510. Under the action of the reset member 162, the two sealing members 530 respectively obtain two forces to move toward each other along the second direction B, thereby driving the two sealing members 530 to move toward each other to cover the ice transport opening 511. Then, the two second matching portions 5525 move toward each other under the action of the two sealing members 530. The arrangement of the two sealing members 530 and the two second matching portions 5525 can effectively reduce the movement stroke of the sealing members 530, thereby effectively increasing the movement reliability of the structure and improving the efficiency of the sealing members 530 moving to cover and remove from the ice transport opening 511.

[0059] In another embodiment of the present application, the first direction A is parallel to the extension direction of the ice transport chute 520. The first mating portion 5524 has two first contact portions 5526 on the side facing the ice transport opening 511, and the second mating portion 5525 has a second contact portion 5527 on the side facing away from the seal 530. At least one of the second contact portions 5527 and the second contact portion 5527 is arranged obliquely relative to the radial cross-section of the movable chute 540, thereby decomposing the thrust of the first mating portion 5524 on the second mating portion 5525 into a force component along the second direction B. Specifically, when the movable chute 540 moves along the first direction A until it extends out of the ice transport opening 511, as the movable chute 540 continues to move along the first direction A until it extends out of the ice transport opening 511, the force exerted by the first contact portions 5526 on the second contact portions 5527 drives the two second mating portions 5525 to move away from each other, causing the seal 530 to move away from the ice transport opening 511. When ice removal is complete, the first drive member 555 drives the movable channel 540 in the first direction A until it retracts into the door body 510. Due to the elastic action of the reset member 162, the two second mating portions 5525 move the seal 530 in the second direction B to cover the ice delivery port 511. This structural arrangement eliminates the need for a separate drive mechanism to drive the reciprocating motion of the seal 530, thereby reducing the use of power components, simplifying the structure, and effectively improving the user experience. Furthermore, the two seals 530 moving toward or away from each other can reduce the travel of the seal 530 in a single direction of the movable channel 540, thereby increasing the reliability of the structure.

[0060] Furthermore, both first contact portions 5526 are inclined surfaces arranged at an angle relative to the radial cross-section of the movable channel 540, and both first contact portions 5526 are inclined toward the direction of movement of the corresponding seal 530 away from the ice delivery opening 511. Both second contact portions 5527 are inclined surfaces arranged at an angle relative to the radial cross-section of the movable channel 540, and both second contact portions 5527 are inclined toward the direction of movement of the corresponding seal 530 toward the ice delivery opening 511. When the movable channel 540 is retracted into the door body 510 and the seal 530 is moved to cover the ice delivery opening 511, the projections of the first contact portions 5526 and the corresponding second contact portions 5527 in the first direction A at least partially overlap. At this point, the two second contact portions 5527 respectively abut the two first contact portions 5526. When the movable channel 540 moves out of the ice delivery opening 511, the two first contact portions 5526 abut the two second contact portions 5527. The force exerted by the first contact portion 5526 on the second contact portion 5527 pushes the two second contact portions 5527 toward each other in the second direction B, thereby disengaging the seal 530 from the ice delivery opening 511. When the first driving member 555 drives the movable channel 540 to retract into the door body 510, the two second contact portions 5527, under the action of the reset member 162, move toward each other in the second direction B until the seal 530 covers the ice delivery opening 511. This process not only disperses the force exerted by the first mating portion 5524 to the two first contact portions 5526, reducing the force borne by the first contact portions 5526, but also effectively reduces the travel of the seal 530, thereby increasing the reliability of the structure. Furthermore, by eliminating the need for a separate driving mechanism to drive the seal 530 in the second direction B, the number of power components can be effectively reduced. This relatively simple structure increases the space within the door body 510, thereby enhancing the user experience.

[0061] In another embodiment of the present application, the reset member 162 includes a reset elastic member 1621 and a sliding rod 1622. Two reset elastic members 1621 are provided. The two reset elastic members 1621 are respectively provided on the side of the corresponding sealing member 530 away from the ice transport port 511. In the process of the first matching portion 5524 pushing the two sealing members 530 to move away from the ice transport port 511, the two reset elastic members 1621 are compressed and store energy. In the process of the movable channel 540 moving back into the door body 510, the two reset elastic members 1621 restore their deformation and push the two sealing members 530 to move toward each other. The sliding rod 1622 is passed through the reset elastic member 1621, and the end of the sliding rod 1622 away from the sealing member 530 is fixed relative to the reset elastic member 1621. The end of the sliding rod 1622 close to the sealing member 530 is passed through the sealing member 530. Specifically, when the first matching portion 5524 pushes the two sealing members 530 to move away from the ice transport port 511, the first matching portion 5524 pushes the second matching portion 5525 to move away from each other along the second direction B along the first direction A. As a result, the two sealing members 530 move away from each other along the second direction B. During the movement of the sealing members 530 away from each other, the sliding rod 1622 is located within the sealing members 530. At this time, the two restoring elastic members 1621 are compressed and store energy. Since the sliding rod 1622 is always located within the sealing member 530, the restoring elastic member 1621 will not be displaced in other directions during the compression process. The sliding rod 1622 can limit the restoring elastic member 1621 to ensure the smoothness of the movement. When the movable channel 540 moves to retract into the door body 510, the two return spring members 1621 recover their deformation, generating two opposing elastic forces in the second direction B, which in turn push the second mating portion 5525 to move toward each other in the second direction B. At this time, the seal 530 moves toward each other in the second direction B to cover the ice delivery port 511, while the end of the sliding rod 1622 closest to the seal 530 remains within the seal 530, meaning that the sliding rod 1622 does not completely disengage from the seal 530. Therefore, during the movement of the seal 530, the sliding rod 1622 remains within the seal 530, preventing the return spring member 1621 from shifting in directions other than the second direction B, which could cause a failure in energy storage. Therefore, this structure ensures the reliability of the movement of the seal 530 and the movable channel 540.

[0062] To prevent personal injury, in some embodiments, the refrigeration unit further includes a baffle 558. Baffle 558 is disposed at the end of the second door 15 where the ice delivery opening 511 is located. Baffle 558 is located on the side of the second door 15 facing away from the housing 11, corresponding to the ice delivery opening 511. The provision of baffle 558 not only prevents users from reaching into the interface between the movable channel 540 and the ice delivery opening 511, potentially preventing personal injury, but also prevents users from bringing debris or other objects into the ice delivery opening 511 during operation, potentially contaminating the ice.

[0063] The above embodiment specifically describes the door assembly 500. The following describes the ice moving assembly 101 in the refrigeration device 10. The ice moving assembly 101 can accelerate ice cubes by projecting, catapulting, or other means, thereby providing power to ensure that ice cubes pass smoothly through the ice moving channel 120. The specific structure of the ice moving assembly 101 can be implemented in a variety of ways, and several of the following are listed below:

[0064] <Ice throwing method>

[0065] See also Figure 11 , Figure 11 It is a partial structural diagram of an embodiment of the refrigeration equipment of the present application. The ice-moving assembly 101 includes an ice-moving portion 110 and a main rotating member 130. Among them, the ice-moving portion 110 is formed with an ice-moving inlet 111, an ice-moving cavity 112 and an ice-moving outlet 113 that are interconnected. Among them, the ice-moving channel 120 is connected to the ice-moving cavity 112 through the ice-moving outlet 113. The main rotating member 130 is rotatably arranged in the ice-moving cavity 112. The ice-moving inlet 111 and the ice-moving outlet 113 are located on the periphery of the main rotating member 130. The main rotating member 130 can rotate along the first main rotation direction X and carry the ice cubes entering the ice-moving cavity 112 from the ice-moving inlet 111 and throw them out from the ice-moving outlet 113 to the ice-moving channel 120.

[0066] In the present application, the ice transfer portion 110 of the ice transfer assembly 101 can be disposed in the first refrigeration compartment 12, and the ice removal assembly 300 is located in the second door 15 above the first refrigeration compartment 12. The ice transfer passage 120 is used to provide a path for ice cubes to move from the first refrigeration compartment 12 to the second door 15. The ice transfer inlet 111 can be connected to the ice making assembly 200, and ice cubes enter the ice transfer chamber 112 from the ice transfer inlet 111. The main rotating member 130 rotates along the first main rotation direction X, carrying the ice cubes and throwing them toward the ice transfer outlet 113. The ice cubes have a certain initial velocity and move from the ice transfer outlet 113 toward the ice transfer passage 120, and ultimately move along the ice transfer passage 120 to the ice removal assembly 300. Since the main rotating member 130 can rotate continuously at a certain speed, the ice cubes coming out of the ice making assembly 200 can be continuously and quickly ejected to the ice taking assembly 300. The ice cubes move quickly and the ice taking efficiency is high, thereby realizing fast and continuous ice taking. The user has a short waiting time for taking ice, and the ice cubes are not easy to melt. The ice cubes are of high quality and are not easy to melt and stick together.

[0067] The main rotating member 130 drives the ice cubes to rotate, so that the ice cubes acquire an initial velocity and then quickly move to the ice removal assembly 300. The ice cubes move directly from the first refrigeration compartment 12 to the ice removal assembly 300. The fast ice movement speed not only improves the ice removal efficiency, but also eliminates the need to install an evaporator in the second refrigeration compartment 13 to keep the ice cubes cold, thereby further improving the volume ratio of the second refrigeration compartment 13.

[0068] In some embodiments, as Figure 11 As shown, the refrigeration device 10 further includes a conveying channel 150. The conveying channel 150 communicates with the ice transfer chamber 112 via the ice transfer inlet 111, and the conveying channel 150 is used to communicate with the ice outlet end of the ice-making assembly 200 to convey ice cubes to the ice transfer chamber 112. The ice inlet end of the conveying channel 150 is positioned higher than the ice transfer inlet 111, and ice cubes enter the ice transfer unit 110 along the conveying channel 150 under the action of gravity. Alternatively, the ice inlet end of the conveying channel 150 can be positioned parallel to or lower than the ice transfer inlet 111, and ice cubes are driven by some power mechanism to move along the conveying channel 150 into the ice transfer chamber 112. Therefore, the ice transfer inlet 111 can be located in the upper half, lower half, or other position of the ice transfer chamber 112, and ice cubes can enter the ice transfer chamber 112 and be stuck in the main rotating member 130 under the action of gravity or other power mechanisms.

[0069] When the ice-moving device 100 of the present application is used, the size of the ice cubes is within a predetermined range, and the main rotating member 130 rotates at a predetermined speed along the first main rotation direction X, the ice cubes can usually be smoothly carried and thrown from the ice-moving outlet 113 to the ice-moving channel 120, and the ice cubes are finally smoothly moved along the ice-moving channel 120 to the ice-taking assembly 300. However, in some special cases, such as when the size of the ice cubes changes greatly, or when the main rotating member 130 rotates while carrying the ice cubes, the ice cubes and the main rotating member 130 are relatively displaced, and when the main rotating member 130 throws the ice cubes into the ice-moving channel 120, the ice cubes fail to obtain the required initial velocity, etc., which will result in the ice cubes being unable to smoothly move along the ice-moving channel 120 to the ice-taking assembly 300. The ice cubes that do not reach the ice-taking assembly 300 will fall back into the ice-moving portion 110 along the ice-moving channel 120. In order to avoid ice blockage affecting the ice-moving efficiency of the ice-moving device 100, in some embodiments, such as Figure 12 As shown, Figure 12 It is a partial structural diagram of another embodiment of the refrigeration equipment of the present application. The ice transfer chamber 112 also includes an ice transfer and return port 119, and the ice transfer device 100 also includes an ice return channel 160. The ice return channel 160 is connected to the ice transfer and return port 119. The ice outlet end of the ice return channel 160 is lower than the ice outlet end of the ice transfer channel 120. The main rotating member 130 can also rotate along the second main rotation direction Y and carry the ice cubes located in the ice transfer chamber 112 to be thrown from the ice transfer and return port 119 to the ice return channel 160. The second main rotation direction Y is opposite to the first main rotation direction X. By setting up the ice return channel 160, when the ice cubes that have not reached the ice retrieval assembly 300 fall back along the ice moving channel 120 and block the ice moving part 110, the ice can be stopped from entering the ice moving part 110 through the ice moving inlet 111, and the main rotating part 130 can rotate along the second main rotation direction Y to throw the ice cubes into the ice return channel 160. Since the ice outlet end of the ice return channel 160 is lower than the ice outlet end of the ice moving channel 120, the ice cubes can be discharged through the ice return channel 160 at a relatively low speed, thereby avoiding the accumulation of ice cubes and blocking the ice moving part 110, thereby ensuring the normal operation of the ice moving device 100.

[0070] The ice inlet end of the conveying channel 150 is connected to the ice-making assembly 200, and the ice outlet end of the conveying channel 150 is connected to the ice-moving unit 110. Ice cubes from the ice-making assembly 200 are moved to the ice-moving unit 110 through the conveying channel 150. The ice outlet end of the ice return channel 160 is connected to the conveying channel 150. The main rotating member 130 rotates in the second main rotation direction Y to return ice cubes blocked in the ice-moving unit 110 to the conveying channel 150 for re-entry into the ice-moving unit 110. Alternatively, the ice outlet end of the ice return channel 160 is connected to the ice-making assembly 200. The main rotating member 130 rotates in the second main rotation direction Y to return ice cubes blocked in the ice-moving unit 110 to the ice-making assembly 200. Specifically, the ice return channel 160 is connected to the ice storage bin of the ice-making assembly 200.

[0071] In some embodiments, as Figure 12As shown, the ice-moving unit 110 includes a force storage area 114. The inner wall of the force storage area 114 surrounds the outer periphery of the main rotating member 130. The main rotating member 130 rotates along a first main rotational direction X to cause ice cubes to sequentially pass through the ice-moving inlet 111, the force storage area 114, and the ice-moving outlet 113 before entering the ice-moving channel 120. Once the ice cube enters the ice-moving inlet 111, because the inner wall of the force storage area 114 surrounds the outer periphery of the main rotating member 130, the main rotating member 130 can grip the ice cube and rotate it a sufficient angle in the first main rotational direction X, thereby achieving sufficient acceleration. When the ice cube continues to rotate until it exits the force storage area 114 and corresponds to the ice-moving outlet 113, it loses its peripheral restraint and moves at a sufficient speed toward the ice-moving channel 120. The ice cube then moves along the ice-moving channel 120 to the ice removal assembly 300. By providing the force storage area 114, ice cubes can be fully accelerated to achieve a sufficient initial velocity, facilitating their passage through the ice transfer channel 120. It should be noted that the initial velocity of ice cubes passing through the force storage area 114 can be varied by adjusting the range of the force storage area 114 and the size and rotational speed of the main rotating member 130. By adjusting various parameters, ice cubes can be moved through the ice transfer channel 120 at an appropriate speed, ensuring that ice cubes can enter the ice retrieval assembly 300 at a certain speed through the ice transfer channel 120 without excessive speed causing collision noise. Similarly, when ice cubes that fail to reach the ice retrieval assembly 300 fall back into the ice transfer unit 110 along the ice transfer channel 120, the main rotating member 130 rotates along the second main rotational direction Y to allow the ice cubes to pass from the force storage area 114 through the ice transfer return opening 119 and enter the ice return channel 160. By providing the force storage area 114 , when the main rotating member 130 rotates along the second main rotating direction Y, the ice cubes can have a certain initial velocity and then be thrown toward the ice return channel 160 through the ice return opening 119 .

[0072] It should be noted that, when the main rotating part 130 carries the ice cubes and rotates along the first main rotation direction X, the ice cubes entering the ice moving chamber 112 from the ice moving inlet 111 may first pass through the ice moving return outlet 119, but at this time the ice cubes rotate at a small angle with the main rotating part 130 and the speed obtained is low, and the ice cubes will not separate from the main rotating part 130 and be thrown out to the ice moving return outlet 119. When the ice cubes continue to rotate with the main rotating part 130 to the corresponding ice moving outlet 113, the ice cubes obtain sufficient speed to separate from the main rotating part 130 and be thrown out to the ice moving outlet 113. Similarly, when the main rotating part 130 carries the ice cubes and rotates along the second main rotation direction Y, the ice cubes may first pass through the ice-moving inlet 111, but at this time the ice cubes rotate at a small angle along with the main rotating part 130 and obtain a low speed, so the ice cubes will not separate from the main rotating part 130 and be thrown out to the ice-moving inlet 111. When the ice cubes continue to rotate with the main rotating part 130 to the corresponding ice-moving return outlet 119, the ice cubes obtain sufficient speed to separate from the main rotating part 130 and be thrown out to the ice-moving return outlet 119.

[0073] To facilitate smooth passage of ice cubes through the ice-moving channel 120 and improve the success rate of ice-moving and throwing, in some embodiments, the outer periphery of the main rotating member 130 is configured to define a first motion trajectory of the ice cubes when the main rotating member 130 rotates along the first main rotational direction X. The tangent direction of the first motion trajectory corresponding to the junction of the force storage area 114 and the ice-moving and ice-discharging outlet 113 lies within the ice-moving channel 120. Consequently, when the main rotating member 130, carrying the ice cubes, rotates to the junction of the force storage area 114 and the ice-moving and ice-discharging outlet 113, the ice cubes are about to escape from the force storage area 114 and move toward the ice-moving and ice-discharging outlet 113. At this point, the direction of motion of the ice cubes lies within the ice-moving channel 120, allowing the ice cubes to smoothly move into the ice-moving channel 120 and then to the ice removal assembly 300. This results in a high success rate for ice-moving and throwing ice cubes with the ice-moving device 100. Specifically, the tangent direction of the connection between the first motion trajectory corresponding to the power storage area 114 and the ice removal outlet 113 coincides with the extension direction of the ice removal section 121 of the ice removal channel 120. The ice cubes have less resistance to movement in the ice removal section 121, and the power required for the main rotating part 130 to drive the ice cubes through the ice removal channel 120 is smaller.

[0074] To facilitate smooth passage of ice cubes through the ice return channel 160 and improve the success rate of ice return and projection, in some embodiments, the outer periphery of the main rotating member 130 defines a second motion trajectory for the ice cubes when the main rotating member 130 rotates in the second main rotational direction Y. The second motion trajectory corresponds to a tangent line at the junction of the power storage area 114 and the ice transfer and return port 119 and lies within the ice return channel 160. Consequently, when the main rotating member 130, carrying the ice cubes, rotates to the junction of the power storage area 114 and the ice transfer and return port 119, the ice cubes are about to escape from the power storage area 114 and move toward the ice transfer and return port 119. At this point, the direction of motion of the ice cubes lies within the ice return channel 160, allowing the ice cubes to smoothly move into the ice return channel 160 and then to the ice-making assembly 200, thereby preventing blockage of the ice transfer unit 110. Specifically, the tangent direction of the connection between the second motion trajectory corresponding to the power storage area 114 and the ice transfer and return port 119 coincides with the extension direction of the ice return channel 160. The resistance of ice cubes to movement in the ice return channel 160 is smaller, and the power required for the main rotating part 130 to drive the ice cubes through the ice return channel 160 is smaller.

[0075] In some embodiments, the ice removal device 100 further includes a first sensor 171 and a second sensor 172. The first sensor 171 is disposed at the ice removal inlet 111 or the conveying channel 150. The first sensor 171 is used to sense the passage of ice cubes, indicating that ice cubes have entered the ice removal chamber 112. The second sensor 172 is disposed at the ice outlet end of the ice removal channel 120. The second sensor 172 is used to sense the passage of ice cubes, indicating that ice cubes have successfully passed through the ice removal channel 120 and moved to the ice removal assembly 300.

[0076] In some embodiments, as Figure 13 As shown, Figure 13 It is a partial structural diagram of the ice moving assembly of another embodiment of the refrigeration equipment of the present application. The ice moving part 110 also includes a connecting area 115 and a third sensor 173. The inner wall of the connecting area 115 is arranged around the outer periphery of the main rotating part 130. The connecting area 115 is connected to the side of the ice moving inlet 111 and the ice moving outlet 113 away from the power storage area 114. The third sensor 173 is arranged in the connecting area 115. The third sensor 173 is used to sense the passage of ice cubes. When the third sensor 173 senses the passage of ice cubes, it indicates that the main rotating part 130 has not thrown the ice cubes to the ice moving outlet 113, and the ice cubes are forced to pass through the connecting area 115. At this time, an ice blockage failure may occur. When the third sensor 173 senses the passage of ice cubes, it can control the ice-making assembly 200 to stop adding ice, and at the same time control the main rotating member 130 to rotate along the second main rotation direction Y, so as to throw the ice cubes blocked in the ice moving chamber 112 to the ice return channel 160 to avoid ice blockage.

[0077] Since the ice cubes move at high speed during the ejection process, there may be friction and collision, so crushed ice may be generated in the cavity. The crushed ice is difficult to be ejected. As the crushed ice accumulates more and more, it will affect the rotation of the main rotating part 130. In some embodiments, the bottom of the ice moving part 110 is provided with a through hole (not shown in the figure) that communicates with the ice moving cavity 112. The ice moving device 100 includes a collecting part 175. The collecting part 175 is arranged below the ice moving part 110. The through hole allows crushed ice to pass through but does not allow whole ice to pass through. The collecting part 175 receives the crushed ice that falls from the through hole. The collecting part 175 and the ice moving part 110 are placed together in the first refrigeration compartment 12. The user can remove and clean the collecting part 175 by opening the first refrigeration compartment 12.

[0078] <Ice Bounce Method>

[0079] See also Figure 14 , Figure 14 This is a schematic diagram of the overall structure of an ice moving device of another embodiment of the refrigeration equipment of the present application.

[0080] The ice removal assembly 101 includes a conveying channel 150, a sorting assembly 180, and an ejection assembly 190. The ice removal channel 120 includes an ice outlet 1222, an ice inlet 1221, and an ejection area 1223. The ice outlet 1222 is located above the ice inlet 1221. The ejection area 1223 is located below the ice inlet 1221. The conveying channel 150 is connected to the ice removal channel 120 through the ice inlet 1221. The sorting assembly 180 is arranged in the conveying channel 150 to transport ice cubes one by one to the ice removal channel 120. Since the ejection area 1223 is located below the ice inlet 1221, the sorting assembly 180 transports the ice cubes one by one through the ice inlet 1221, and the ice cubes move from the ice inlet 1221 to the ejection area 1223 under the action of gravity. The ejection assembly 190 is disposed at one end of the ice transfer passage 120 away from the ice outlet 1222. The ejection assembly 190 is used to eject a predetermined number of ice cubes located in the ejection area 1223 toward the ice outlet 1222. The sorting assembly 180 cooperates with the ejection assembly 190, which transports the ice cubes one by one to the ice transfer passage 120. The ejection assembly 190 then ejects a predetermined number of ice cubes located in the ejection area 1223 toward the ice outlet 1222.

[0081] In this embodiment of the present application, the sorting assembly 180, conveying channel 150, and ejection assembly 190 may be located in the first refrigeration compartment 12. The ice retrieval assembly 300 is located in the second door 15 above the first refrigeration compartment 12. The ice transfer channel 120 provides a path for ice cubes to move from the first refrigeration compartment 12 to the second door 15. The ejection assembly 190 ejects ice cubes toward the ice outlet 1222. Ice cubes have a certain initial velocity, moving from the ejection area 1223 toward the ice outlet 1222 and ultimately along the ice transfer channel 120 to the ice retrieval assembly 300. Because the ejection assembly 190 continuously ejects ice cubes at a constant speed, ice cubes from the ice making assembly 200 are continuously and rapidly ejected to the ice retrieval assembly 300. This results in rapid ice movement and efficient ice retrieval, enabling rapid and continuous ice retrieval. Users also minimize waiting time for ice retrieval. Furthermore, the ice cubes are less likely to melt, resulting in high-quality ice cubes and less chance of them sticking together.

[0082] The ejection assembly 190 can drive the ice cubes to be ejected, so that the ice cubes gain an initial velocity and then quickly move to the ice removal assembly 300. The ice cubes move directly from the first refrigeration compartment 12 to the ice removal assembly 300. The fast ice movement speed not only improves the ice removal efficiency, but also eliminates the need to install an evaporator in the second refrigeration compartment 13 to keep the ice cubes cold, thereby further improving the volume ratio of the second refrigeration compartment 13.

[0083] It should be noted that the predetermined number can be one, two, or more. The predetermined number matches the driving force of ejection assembly 190. To ensure the success rate of ice ejection, the driving force of ejection assembly 190 can eject more than the predetermined number of ice cubes toward the ice outlet. Ejection assembly 190 can eject one, two, or another number of ice cubes located in ejection area 1223 toward ice outlet 1222 in a single ejection.

[0084] The ejection assembly 190 includes a push plate 191 and an electromagnetic ejector 192. The push plate 191 is movably arranged in the ice transfer channel 120 along the extension direction of the ice transfer channel 120. The electromagnetic ejector 192 is arranged on the side of the push plate 191 away from the ice outlet 1222. The output end of the electromagnetic ejector 192 is connected to the push plate 191. The electromagnetic ejector 192 can drive the push plate 191 to eject a predetermined distance from the ejection area 1223 toward the ice outlet 1222. The ice cubes acquire a certain initial velocity under the push of the push plate 191 and then move toward the ice outlet 1222. The electromagnetic ejector 192 can also drive the push plate 191 back to the ejection area 1223. Specifically, the electromagnetic ejector 192 can control the ejection or retraction of the push plate 191 by turning the current on and off. By controlling the magnitude of the current, the ejection speed of the push plate 191 can be controlled, thereby adjusting the ejection speed of the ice cubes.

[0085] In some embodiments, the conveying channel 150 includes a conveying portion 152, a guide portion 153, and a funnel portion 154. A sorting assembly 180 is disposed on the conveying portion 152. The conveying portion 152 includes an inlet end 1521 and an outlet end 1522, with the outlet end 1522 being higher than the ice inlet 1221. The guide portion 153 connects the outlet end 1522 and the ice inlet 1221. The funnel portion 154 is disposed above the inlet end 1521 and is configured to receive ice cubes entering the conveying portion 152. Because the outlet end 1522 is higher than the ice inlet 1221 and the guide portion 153 connects the outlet end 1522 and the ice inlet 1221, ice cubes can move from the outlet end 1522 to the ice inlet 1221 under the action of gravity. The diameter of the funnel portion 154 gradually increases from one end of the funnel portion 154 connected to the conveying portion 152 to the end away from the conveying portion 152, so that the funnel portion 154 facilitates the ice cubes removed from the ice making assembly 200 to enter the conveying channel 150, thereby improving the success rate of the ice cubes entering the conveying channel 150.

[0086] Furthermore, the outlet end 1522 of the conveying portion 152 is higher than the inlet end 1521 of the conveying portion 152, so that the sorting component 180 disposed in the conveying portion 152 needs to transport the ice cubes at a lower position to a higher position. The sorting component 180 can raise the height of the ice cubes to a certain extent, so that the ice cubes can be closer to the second refrigeration compartment 13, shortening the height that the ice cubes need to rise along the ice moving channel 120, reducing the driving force required by the ejection component 190 to drive the ice cubes to rise, and improving the success rate of ice ejection.

[0087] The sorting component 180 for delivering ice cubes one by one to the ice moving channel 120 may have various implementation structures, for example:

[0088] In some embodiments, the conveying portion 152 is linear. The sorting assembly 180 includes a transmission wheel group 181, a transmission belt 182, a partition 183 and a first power member (not shown in the figure). The transmission wheel group 181 is arranged on the conveying portion 152, and the transmission wheel group 181 includes at least two transmission wheels 1811 arranged at intervals, and the transmission wheels 1811 are arranged at intervals along the length direction of the conveying portion 152. The transmission wheel 1811 is rotatably supported on the conveying portion 152. The transmission belt 182 is wound around the transmission wheel group 181. The first power member drives the transmission wheel 1811 to rotate, so that the transmission belt 182 is transmitted as the transmission wheel 1811 rotates. A plurality of partitions 183 are provided, and a plurality of partitions 183 are spaced apart on the transmission belt 182. Each adjacent two partitions 183 are used to receive an ice cube. The provision of partition 183 facilitates the movement of ice cubes along the conveyor belt 182 toward the guide portion 153, thereby enhancing the stability of the ice cubes on the conveyor belt 182. Partition 183 also separates the ice cubes, preventing them from sticking together. As the ice cubes move along the ice conveyor belt 182 to the end of the sorting assembly 180 near the guide portion 153, partition 183 gradually rotates from above the conveyor belt 182 to below it. The ice cubes, freed from the barrier provided by partition 183, fall under gravity into the guide portion 153 and move along it to the ice transfer channel 120. The speed at which the first power member drives the transmission wheel 1811 can be adaptively adjusted based on the speed at which the ejection assembly 190 ejects the ice cubes from the ice transfer channel 120.

[0089] In some embodiments, the ice moving channel 120 includes an ice moving section 121 and a guide section 122. The ejection area 1223 and the ice inlet 1221 are provided in the ice moving section 121. The ice moving section 121 is connected to the conveying channel 150 through the ice inlet 1221. The guide section 122 is connected to the ice moving section 121 and is bent toward one side for guiding to the ice retrieval assembly 300. When the ice cube moves in the ice moving section 121, the ice cube rises a sufficient distance along the ice moving section 121; the guide section 122 is used to turn and connect to the ice retrieval assembly 300. When the ice cube moves to the guide section 122, the ice cube has risen a sufficient distance, and the guide section 122 is used to change the moving direction of the ice cube so that it moves toward the ice retrieval assembly 300. There is a smooth transition between the ice moving section 121 and the guide section 122.

[0090] Specifically, the ice moving section 121 can be arranged in a vertical direction to shorten the distance that ice cubes need to rise along the ice moving section 121. Of course, the ice moving section 121 can also be extended in a direction with a smaller angle to the vertical direction; alternatively, the ice moving channel 120 can be an entire arc-shaped ice moving channel 120, which is used to extend from the ice moving outlet 1222 to the ice retrieval assembly 300, ensuring that ice cubes can rise stably and communicate with the ice retrieval assembly 300.

[0091] Specifically, the angle between the extension direction of the guide section 122 and the ice-moving section 121 at the connection point is greater than 90° and less than 180°, so as to prevent the ice cubes from falling back into the ice-moving section 121 due to excessive turning angle when entering the guide section 122 from the ice-moving section 121, thereby ensuring that the ice cubes can smoothly pass through the ice-moving channel and move to the ice-taking assembly 300.

[0092] To ensure that sorting assembly 180 can smoothly transport ice cubes into ice transfer channel 120, ice transfer device 100 also includes a first sensor 1224. First sensor 1224 is located at ice inlet 1221. First sensor 1224 senses the passage of ice cubes, indicating that ice cubes have entered the ice transfer chamber. When first sensor 1224 senses the passage of ice cubes, the ice cubes fall through ice inlet 1221 into ejection zone 1223. Ejection assembly 190 then prepares to perform an ejection operation, driving the ice cubes in ejection zone 1223 to eject toward ice outlet 1222.

[0093] To ensure that the ejection assembly 190 successfully ejects ice cubes out of the ice outlet 1222 of the ice removal channel 120, in some embodiments, the ice removal device 100 further includes a second sensor 1225. The second sensor 1225 is disposed at the ice outlet 1222. The second sensor 1225 senses the passage of ice cubes, indicating that ice cubes have successfully passed through the ice removal channel 120 and moved to the ice removal assembly 300. When the second sensing element 1225 senses the passage of ice cubes, the sorting component 180 can continue to transport ice cubes to the ice moving channel 120, and the ejection component 190 can prepare for the next ice ejection operation; when the ejection component 190 performs an ejection operation, the second sensing element 1225 still does not sense the passage of ice cubes, which means that the ice cubes did not pass through the ice outlet 1222 after being ejected, but still fell back to the ejection area 1223 along the ice moving channel 120. At this time, an ice jam may occur. The sorting component 180 can be controlled to stop feeding ice, and the ejection component 190 can be controlled to perform another ice ejection operation to eject the ice cubes that were not successfully ejected.

[0094] In some other embodiments, the ice moving device 100 further includes a weight sensor (not shown in the figure). The weight sensor is arranged on the push plate 191. If the ice cube enters the ice moving channel 120 and falls on the push plate 191, the weight sensor can sense the change of the ice cube, and the ejection component 190 can prepare to perform an ejection operation to drive the ice cube located in the ejection area 1223 to pop out toward the ice outlet 1222; if the ejection component 190 ejects the ice cube toward the ice outlet 1222, the ice cube does not pass through the ice outlet 1222 but still falls back to the ejection area 1223 along the ice moving channel 120, the weight sensor can sense the weight change again, and then control the sorting component 180 to pause the ice entry, and control the ejection component 190 to perform an ice ejection operation again to eject the ice cube that was not successfully ejected.

[0095] The first sensing element 1224 can be used in conjunction with the second sensing element 1225 or the weight sensor to accurately detect the status of ice cubes in the ice moving device 100 .

[0096] The above embodiments specifically describe several possible implementations of the ice removal assembly 101 structure. The ice removal channel 120 of the present application is described in detail below:

[0097] Please continue reading Figure 15 and Figure 16 , Figure 15 This is a structural diagram of another embodiment of the refrigeration equipment of the present application, in which an ice removal channel is provided on the doors of the first refrigeration compartment and the second refrigeration compartment; Figure 16 This is a cross-sectional structural diagram of another embodiment of the refrigeration equipment of the present application, in which the ice moving channels are arranged on the doors of the first refrigeration compartment and the second refrigeration compartment.

[0098] The ice-moving portion 110 is provided on the first door body 14. The ice-moving channel 120 includes a first sub-channel 123 and a second sub-channel 124, which are connected in sequence. The first sub-channel 123 is provided on the first door body 14, and the second sub-channel 124 is provided on the second door body 15. The second sub-channel 124 is connected to the ice-removing assembly 300. The first sub-channel 123 is also connected to the ice-moving outlet 113 of the ice-moving portion 110. The ice-moving assembly 101 can drive ice cubes to move out of the ice-moving channel 120. The ice cubes pass through the first sub-channel 123 and the second sub-channel 124 in sequence and then enter the ice-removing assembly 300.

[0099] By arranging the first sub-channel 123 in the first door body 14 and the second sub-channel 124 in the second door body 15, the internal space of the first refrigeration compartment 12 and the second refrigeration compartment 13 is not occupied, the volume ratio of the refrigeration device 10 is improved, and the appearance of the refrigeration device 10 is not increased by additional protrusions, thereby optimizing the appearance.

[0100] Because the first sub-channel 123 is located in the first door body 14 and the second sub-channel 124 is located in the second door body 15, there is a certain gap between the first door body 14 and the second door body 15. The first door body 14 and / or the second door body 15 adopt the door body assembly 500 of the above embodiment. When the first door body 14 and / or the second door body 15 are opened, the second sub-channel 124 is staggered with the first sub-channel 123. When the first door body 14 and / or the second door body 15 are closed on the box body 11, the second sub-channel 124 is connected to the first sub-channel 123.

[0101] In addition, the ice transfer inlet 111 of the ice transfer unit 110 disengages from the ice-making assembly 200 when the first door 14 is opened. After the first door 14 is closed, the ice transfer inlet 111 engages with the ice outlet of the ice-making assembly 200, without affecting the normal operation of the ice transfer unit 110. To facilitate the docking of the ice transfer inlet 111 and the ice-making assembly 200, the diameter of the ice transfer inlet 111 is larger than the diameter of the ice outlet of the ice-making assembly 200. When the first door 14 is closed on the housing 11, the ice transfer inlet 111 engages with the outside of the ice outlet of the ice-making assembly 200, facilitating the entry of ice cubes into the ice transfer inlet 111 through the ice outlet of the ice-making assembly 200. The ice outlet of the ice-making assembly 200 may include the ice outlet of the ice storage bin of the ice-making assembly 200 or the ice outlet of the conveying channel 150.

[0102] In some embodiments, the first door body 14 is rotatably disposed on the cabinet body 11. In other embodiments, the first refrigeration compartment 12 includes a first drawer, the first drawer is push-pull disposed on the cabinet body 11, and the first door body 14 is fixed to the first drawer. When the ice-moving portion 110 is disposed on the first door body 14, as the first door body 14 rotates the switch or pushes and pulls the switch, the ice-moving portion 110 and the ice-moving channel 120 located in the first door body 14 will move with the first door body 14. At this time, the first sub-channel 123 is staggered with the second sub-channel 124 as the first door body 14 is opened. After the first door body 14 is closed, the first sub-channel 123 and the second sub-channel 124 can be arranged to face each other without affecting the passage of ice cubes.

[0103] When the refrigeration device 10 is a double-door refrigeration device 10, the second door body 15 includes two second sub-door bodies. The second sub-door bodies are relatively narrow, and the space available for the ice removal assembly 300 in the second sub-door body is limited. Furthermore, since the ice making assembly 200 is located near one side wall and the ice transfer unit 110 is located in the first door body 14, in order to facilitate the docking of the ice transfer channel 120 and to make it easier for ice cubes ejected from the ice transfer unit 110 into the ice transfer channel 120 to rise along the ice transfer channel 120, the second sub-channel 124 of the ice transfer channel 120 is located on the side of the ice removal assembly 300 near the rotation axis of the second door body 15. In this case, in conjunction with the location of the ice transfer unit 110, the second sub-channel 124 is linearly connected to the first sub-channel 123, further facilitating the movement of ice cubes through the ice transfer channel 120 to the ice removal assembly 300.

[0104] Of course, in some single-door refrigerators, the second door 15 is a single door, and the width of the second door 15 is relatively wide, which provides more space for the ice removal assembly 300. The second sub-channel 124 of the ice transfer channel 120 can be selectively arranged on the side of the ice removal assembly 300 that is away from or close to the rotation axis of the second door 15. In this case, in conjunction with the location of the ice transfer unit 110, the second sub-channel 124 is linearly connected to the first sub-channel 123, which is more conducive to ice cubes moving through the ice transfer channel 120 to the ice removal assembly 300.

[0105] Of course, the ice moving channel 120 can also be set at other positions of the refrigeration equipment 10 in coordination with the structure of the box 11 or the position of other components such as the ice moving part 110, which is not limited here.

[0106] It is understood that the meaning of "plurality" herein is at least two, such as two, three, etc., unless there is a special limitation. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units that are inherent to these processes, methods, products or devices. The term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the related objects before and after are in an "or" relationship.

[0107] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
