Description

Technical Field

[0001] The present application relates to the technical field of household appliances, for example, to a shelf assembly for a refrigeration device and a refrigeration device. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature and is also a civilian product that keeps food or other items in a constant low temperature state. A refrigerator is one of the necessities of family life in modern society. Especially in summer, in order to ensure that food does not spoil in a short time, it is necessary to place the food in the refrigerator for storage. In order to meet the needs of users to store items, shelves for holding items are provided in the storage compartment of the refrigerator.

[0003] Currently, the shelves in the storage compartment of a refrigerator are generally supported and fixed by the ribbing on the inner surface of the inner liner. In the fixing method of the shelves of existing refrigerators, since there is no upper and lower limit and front and back limit for the shelves, the shelves are prone to shaking, resulting in the risk of the shelves coming out and falling off during packaging and transportation. To avoid damage caused by the up and down vibration of the shelves during transportation, an improved solution is proposed.

[0004] A related technology discloses a refrigerator shelf. The refrigerator shelf includes a placing plate and a limiting component. The limiting component includes a clamping strip and a locking pin. The clamping strip is arranged at the front end of the placing plate, and the locking pin is telescopically arranged on both sides of the clamping strip. A clamping groove is provided at the rear end of the clamping strip, and the front end of the placing plate is inserted into the clamping groove. The clamping groove and the placing plate are in an interference fit. A receiving groove is provided on the bottom surface of the clamping strip along the length direction of the clamping strip, and a first limiting portion and a second limiting portion are provided at both ends of the receiving groove; a handle is provided in the middle of the locking pin, and the locking pin passes through the first limiting portion and the second limiting portion, and the handle is located between the first limiting portion and the second limiting portion.

[0005] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related technology:

[0006] In the related technology, the shelf is fixed by a clamping strip and a locking pin. The locking pins are arranged on both sides of the clamping strip. When the user disassembles or fixes the shelf, it is necessary to respectively pull the handles on both sides to make the clamping strip extend or contract, which requires two operations and is not convenient to use. Especially when the limiting component is arranged at the rear end of the shelf, it is even more inconvenient for the user.

[0044] 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.

[0045] For the convenience of describing this embodiment, as Figure 1 shown, the left-right direction is the width direction of the shelf 10, that is, the extending direction of the shaft tube 10.

[0046] Combined with Figures 1 to 7As shown in the figure, an embodiment of the present disclosure provides a shelf assembly for a refrigeration device. The shelf assembly for the refrigeration device includes: a shelf 10, a shaft cylinder 20, and a telescopic assembly 30. The shelf 10 is provided with one of a slide rail 11 or a slider 12, and the slide rail 11 or the slider 12 extends along the width direction of the shelf 10; the shaft cylinder 20 extends along the width direction of the shelf 10, and the shaft cylinder 20 is rotatably connected to the shelf 10. The shaft cylinder 20 is provided with a slideway, and the slideway is spiral; the telescopic assembly 30 is nested with the shaft cylinder 20 and the telescopic assembly 30 is slidably connected to the slideway of the shaft cylinder 20. The telescopic assembly 30 is provided with the other of the slider 12 or the slide rail 11, and the slider 12 is adapted to the slide rail 11, so that the telescopic assembly 30 is slidably connected to the shelf 10; wherein, the number of the telescopic assemblies 30 is two, which are respectively arranged at both ends of the shaft cylinder 20. The number of the slideways and the slide rails 11 is two and both are arranged in one-to-one correspondence with the telescopic assembly 30. When the shaft cylinder 20 rotates, it drives the two telescopic assemblies 30 to expand and contract along the extending direction of the shaft cylinder 20, so that the two telescopic assemblies 30 extend out of the shelf 10 or retract into the shelf 10.

[0047] By adopting the shelf assembly for the refrigeration device of the embodiment of the present disclosure, by providing one of the slide rail 11 or the slider 12 on the shelf 10 and providing the slider 12 adapted to the slide rail 11 or the slide rail 11 adapted to the slider 12 on the telescopic assembly 30, the telescopic assembly 30 can be slidably connected to the shelf 10, and the telescopic assembly 30 can slide along the width direction of the shelf 10. The width direction of the shelf 10 is also Figure 1 the left-right direction in the figure.

[0048] By providing the shaft cylinder 20 and rotatably connecting the shaft cylinder 20, the shelf 10 can support the shaft cylinder 20 and the shaft cylinder 20 can rotate relative to the shelf 10. By providing a spiral slideway on the shaft cylinder 20 and slidably connecting the telescopic assembly 30 to the slideway, in this way, when the user rotates the shaft cylinder 20, the telescopic assembly 30 is driven by the slideway and is limited by the slide rail 11 to expand and contract along the extending direction of the shaft sleeve.

[0049] By providing two telescopic assemblies 30 at both ends of the shaft cylinder 20 and providing two slideways on the shaft cylinder 20, when the shaft cylinder 20 rotates, it can drive the telescopic assemblies 30 on both sides to expand and contract simultaneously. That is to say, when the shaft cylinder 20 rotates, the two telescopic assemblies 30 can move towards each other or away from each other, so that the telescopic assemblies 30 contract or extend out of the shelf. Compared with the adjustment method in the related art, in this embodiment, only by rotating the shaft cylinder 20, the telescopic assemblies 30 on both sides can be extended or contracted, which can effectively improve the convenience of user operation.

[0050] Specifically, in combination with Figure 1 and Figure 2As shown, the spiral direction of the slideway is set in the clockwise direction. When the user rotates the shaft cylinder 20 forward, the telescopic assembly 30 can be contracted. When the user rotates the shaft cylinder 20 reversely, the telescopic assembly 30 can be extended.

[0051] Optionally, the shaft cylinder 20 is arranged at the front end of the shelf 10.

[0052] In this way, it is convenient for the user to operate the shaft cylinder 20, improving the convenience of user operation.

[0053] Optionally, the shaft cylinder 20 is arranged at the rear part of the shelf 10.

[0054] In this way, by arranging the shaft cylinder 20 at the rear part of the shelf 10, the telescopic assembly 30 is also arranged at the rear part of the shelf 10, which can reduce the occupation of the space of the shelf 10, avoid the telescopic assembly 30 from blocking the user from placing items, and improve the convenience of user use.

[0055] Optionally, the telescopic assembly 30 includes: a sleeve 31, a fixed seat 32 and a connecting rod 33. One end of the sleeve 31 is arranged inside the shaft cylinder 20 and is slidably connected with the shaft cylinder 20. The other end of the sleeve 31 extends in a direction away from the shaft cylinder 20. A slider 12 is arranged on the outer wall of the other end of the sleeve 31. The fixed seat 32 is arranged inside the sleeve 31. The connecting rod 33 is arranged inside the fixed seat 32 and extends outside the sleeve 31 and is located in the chute 21, so that the connecting rod 33 is connected with the chute 21 of the shaft cylinder 20. Wherein, the shelf 10 is provided with a slide rail 11 adapted to the slider 12. The sleeve 31 has an extended position and a contracted position. By rotating the shaft cylinder 20, the two sleeves 31 move between the extended position and the contracted position along the extension direction of the shaft cylinder 20, so that the sleeve 31 extends out of the shelf 10 or retracts into the shelf 10.

[0056] Adopting the shelf assembly for a refrigeration device in the embodiment of the present disclosure, by arranging the slider 12 on the sleeve 31 and arranging the slide rail 11 adapted to the slider 12 on the shelf 10, the slide rail 11 can not only slidably connect the sleeve 31 with the shelf 10, but also prevent the sleeve 31 from rotating relative to the shaft cylinder 20. Furthermore, the sleeve 31 is rotatably connected with the shaft cylinder 20, and when the shaft cylinder 20 rotates, it will not drive the sleeve 31 to rotate.

[0057] By arranging the connecting rod 33 and extending the connecting rod 33 into the chute 21, the sleeve 31 can be slidably connected with the chute 21 of the shaft cylinder 20. In this way, when the shaft cylinder 20 rotates, the connecting rod 33 moves along the extension direction of the shaft cylinder 20 under the limitation of the chute 21, and then the sleeve 31 moves between the extended position and the contracted position, so that the sleeve 31 extends out of the shelf 10 to be suitable for connecting with the refrigeration device or retracts into the shelf 10 to disconnect from the refrigeration device.

[0058] Optionally, the helix of the chute 21 is less than one turn, and the angle between the line connecting the first end of the chute 21 and the axis of the shaft cylinder 20 and the line connecting the second end of the chute 21 and the axis of the shaft cylinder 20 is greater than 30 degrees and less than 180 degrees.

[0059] By adopting the shelf assembly for a refrigeration device according to the embodiment of the present disclosure, the helix of the chute 21 is set to be less than one turn. In this way, it is not necessary to rotate the shaft cylinder 20 one turn or multiple turns to complete the contraction of the sleeve 31, so that the sleeve 31 can be quickly contracted or extended, improving the convenience of user operation. By setting the angle between the line connecting the first end of the chute 21 and the axis of the shaft cylinder 20 and the line connecting the second end of the chute 21 and the axis of the shaft cylinder 20 to be greater than 30 degrees and less than 180 degrees. In this way, when the angle is less than 30 degrees, the resistance for the user to rotate the shaft cylinder 20 is relatively large, and it is difficult for the user to rotate the shaft cylinder 20; when the angle is greater than 180 degrees, the angle for the user to rotate the shaft cylinder is too large, and it is inconvenient for the user to rotate the shaft cylinder 20.

[0060] Preferably, the angle between the line connecting the first end of the chute 21 and the axis of the shaft cylinder 20 and the line connecting the second end of the chute 21 and the axis of the shaft cylinder 20 is 90 degrees.

[0061] In this way, it can not only avoid the problem that the angle is too small and the user has difficulty rotating due to the large resistance, but also avoid the problem that the angle is too large and the user has difficulty operating due to the large angle to be rotated.

[0062] Optionally, the length dimension of the slide rail 11 is equal to the distance between the first end and the second end of the slideway.

[0063] In this way, the moving distance of the sleeve 31 can be jointly defined by the slide rail 11, the slider 12, the connecting rod 33 and the chute 21, avoiding the situation that the connecting rod 33 and the chute 21 are overstressed and broken or damaged.

[0064] Optionally, buffer members are provided at both ends of the slide rail 11.

[0065] In this way, by providing the buffer members, the impact force between the sleeve 31 and the slide rail 11 or the slider 12 of the shelf 10 can be reduced, and the impact noise can be decreased.

[0066] Specifically, the buffer member can be a rubber pad or a silica gel pad. It can be understood that the specific form of the buffer member is not unique.

[0067] Optionally, the shelf assembly for a refrigeration device further includes: an elastic member 40, the elastic member 40 is arranged in the shaft cylinder 20, one end of the elastic member 40 is connected to the shaft cylinder 20, and the other end of the elastic member 40 is connected to the sleeve 31; wherein, when the sleeve 31 moves towards the shaft cylinder 20, the elastic member 40 is compressed.

[0068] Using the shelf assembly for a refrigeration device according to an embodiment of the present disclosure, by providing an elastic member 40, the elastic member 40 can drive the sleeve 31 to move in a direction away from the shaft cylinder 20. That is to say, the elastic member 40 can cause the sleeve 31 to extend out of the shaft cylinder 20. In this way, the elastic member 40 can automatically extend the sleeve 31 out of the shaft cylinder 20. By setting the elastic member 40 to be compressed when the sleeve 31 moves towards the shaft cylinder 20, that is to say, the elastic member 40 can drive the sleeve 31 to move to the extended position, ensuring that the sleeve 31 always remains in the extended position and avoiding the situation where the shelf 10 cannot be fixed due to the sleeve 31 shrinking caused by vibration or other reasons. In addition, by setting the elastic member 40 to be compressed when the sleeve 31 moves towards the shaft cylinder 20, that is to say, when the sleeve 31 is in the retracted position, the compression amount of the elastic member 40 reaches the maximum, which can avoid the situation where the connecting rod 33 collides with the end of the sliding groove 21 and causes damage or breakage due to the user rotating the handle 50 too fast.

[0069] Specifically, a support wall is provided inside the shaft cylinder 20, and the support wall seals the shaft cylinder 20. The elastic member 40 is a spring, one end of the spring is connected to the support wall, and the other end of the spring is connected to the sleeve 31.

[0070] In this way, when there is no external force acting on the shaft cylinder 20, it can move in a direction away from the shaft cylinder 20 under the action of the spring until the shaft cylinder 20 moves to the extended position, thereby realizing the automatic extension of the shaft cylinder 20.

[0071] It should be noted that the elastic member 40 can also be a polyurethane elastomer, a rubber elastomer, etc. It can be understood that the specific form of the elastic member 40 is not unique.

[0072] Optionally, the connecting rod 33 is telescopically connected to the fixed seat 32, and the connecting rod 33 can extend out of or retract into the sleeve 31 to facilitate the connection of the telescopic assembly 30.

[0073] Using the shelf assembly for a refrigeration device according to an embodiment of the present disclosure, when the telescopic assembly 30 is connected to the shaft cylinder 20, the connecting rod 33 retracts into the interior of the sleeve 31. When the sleeve 31 is installed in place, the connecting rod 33 extends and extends into the sliding groove 21, which can improve the connection reliability between the telescopic assembly 30 and the shaft cylinder 20.

[0074] Specifically, as shown in Figure 3 and Figure 6 a through hole is formed at the bottom of the fixed seat 32, the through hole is adapted to the bottom of the connecting rod 33, an abutting portion 332 is formed by the outward protrusion of the middle portion of the connecting rod 33, the spring is sleeved on the connecting rod 33, one end of the spring is connected to the abutting portion 332, and the other end of the spring is connected to the fixed seat 32.

[0075] In this way, the connecting rod 33 can be telescopically connected to the fixed seat 32, which can not only reduce costs but also ensure the reliability of the connection.

[0076] Optionally, the shelf assembly for the refrigeration device further includes a motor. The motor is disposed within the shaft cylinder 20 and is drivingly connected to the connecting rod 33 for driving the connecting rod 33 to extend or retract into the sleeve 31.

[0077] In this way, the connecting rod 33 can be automatically telescopically connected to the fixed seat 32, and the motor can drive the connecting rod 33 to automatically extend or retract into the sleeve 31.

[0078] It should be noted that the specific form of the telescopic connection between the connecting rod 33 and the fixed seat 32 is not unique.

[0079] Optionally, a mounting groove 22 is partially recessed on the inner wall surface of the shaft cylinder 20. The mounting groove 22 extends along the extending direction of the shaft cylinder 20 to the sliding groove 21. The mounting groove 22 is adapted to the connecting rod 33 to facilitate the installation of the sleeve 31 and the shaft cylinder 20.

[0080] By adopting the shelf assembly for the refrigeration device of the present disclosure, by providing the mounting groove 22 on the inner wall surface of the shaft cylinder 20 and adapting the mounting groove 22 to the connecting rod 33, on the one hand, the mounting groove 22 can accommodate the connecting rod 33, and on the other hand, the mounting groove 22 and the connecting rod 33 can define the angle between the shaft cylinder 20 and the sleeve 31 during the installation process, improving the installation convenience of the sleeve 31 and the shaft cylinder 20.

[0081] Optionally, a mounting inclined surface 23 is provided at the connection between the sliding groove 21 and the mounting groove 22 to facilitate the installation of the connecting rod 33 and the sliding groove 21.

[0082] By adopting the shelf assembly for the refrigeration device of the present disclosure, by providing the mounting inclined surface 23 at the connection between the sliding groove 21 and the mounting groove 22, and the mounting inclined surface 23 is inclined upward along the contraction direction of the sleeve 31. When the sleeve 31 is installed into the shaft cylinder 20, the connecting rod 33 can extend out of the sliding groove 21 along the mounting inclined surface 23, improving the installation convenience of the sleeve 31 and the shaft cylinder 20.

[0083] Optionally, an anti - detachment structure 331 is provided at the top end of the connecting rod 33, and the anti - detachment structure 331 protrudes circumferentially along the connecting rod 33.

[0084] In this way, by providing the anti - detachment structure 331 at the top end of the connecting rod 33 and the anti - detachment structure 331 protruding circumferentially along the connecting rod 33, the connecting rod 33 can be prevented from detaching from the sliding groove 21, improving the connection stability between the connecting rod 33 and the sliding groove 21.

[0085] Optionally, the abutting portion 332 is adapted to the size of the fixed seat 32 so that the wall surface of the abutting portion 332 abuts against the inner side wall of the fixed seat 32.

[0086] In this way, when the connecting rod 33 is located within the fixed seat 32, under the limitation of the abutting portion 332 and the fixed seat 32, the connecting rod 33 can only move relative to the fixed seat 32 in the up and down direction, which can prevent the direction of the connecting rod 33 from being unfixed after compression, thereby improving the convenience of connecting the connecting rod 33 to the sliding groove 21.

[0087] Optionally, the opening area of the end of the mounting groove 22 facing away from the shaft cylinder 20 gradually decreases along the direction in which the sleeve 31 contracts.

[0088] In this way, by gradually decreasing the opening area of the end of the mounting groove 22 facing away from the shaft cylinder 20 along the direction in which the sleeve 31 contracts, when connecting the telescopic assembly 30 to the shaft cylinder 20, the connecting rod 33 can be compressed by the end of the mounting groove 22, facilitating the insertion of the connecting rod 33 into the fixed seat 32, so as to facilitate the insertion of the telescopic assembly 30 into the shaft cylinder 20, and further improving the convenience of connecting the telescopic assembly 30 to the shaft cylinder 20.

[0089] Optionally, the shelf assembly for a refrigeration device further includes: a handle 50, and the handle 50 is provided on the outer wall surface of the shaft cylinder 20 to facilitate the rotation of the shaft cylinder 20.

[0090] By using the shelf assembly for a refrigeration device according to the embodiment of the present disclosure, by providing the handle 50 and disposing the handle 50 on the outer wall surface of the shaft cylinder 20, the user can drive the shaft cylinder 20 to rotate by rotating the handle 50. Compared with the operation method of directly rotating the shaft cylinder 20, it is more convenient for the user to operate, reduces the operation difficulty of the user, and can drive its rotation with a relatively small force.

[0091] Specifically, the handle 50 is provided at the middle of the shaft cylinder 20 and corresponding to the second end of the sliding groove 21.

[0092] In this way, by disposing the handle 50 at the middle of the shaft cylinder 20 and corresponding to the second end of the sliding groove 21, the acting force received by the handle 50 can be evenly applied to both sides of the shaft cylinder 20, ensuring uniform stress on the shaft cylinder 20 and improving the reliability of the device.

[0093] Optionally, the handle 50 has a flat plate structure and extends along the extending direction of the shaft cylinder 20, and the length of the handle 50 is slightly less than the distance between the two sliding ways.

[0094] In this way, the grippable area of the handle 50 can be increased, further improving the convenience of user operation.

[0095] It should be noted that the handle 50 can also have a cylindrical structure. The specific structural form of the handle 50 is not unique, including but not limited to the specific structural form in this embodiment, and can be flexibly adjusted.

[0096] Optionally, the shelf assembly for a refrigeration device further includes: a bracket 60, the bracket 60 is disposed on the shelf 10, the number of brackets 60 is two, the two brackets 60 are respectively disposed on both sides of the shaft cylinder 20, and are both rotatably connected to the shaft cylinder 20.

[0097] By using the shelf assembly for a refrigeration device according to the embodiment of the present disclosure, by providing the bracket 60, the connection between the shaft cylinder 20 and the shelf 10 is ensured to be stable. By providing two brackets 60 and disposing the two brackets 60 on both sides of the shaft cylinder 20, the brackets 60 can support both sides of the shaft cylinder 20, and the shaft cylinder 20 can be kept stable.

[0098] Specifically, the bracket 60 is a support plate, which defines an installation opening, and the installation opening is adapted to the shaft cylinder 20 so that the bracket 60 is sleeved on the shaft cylinder 20, and the two are rotatably connected.

[0099] In this way, the shaft cylinder 20 can be installed in the installation opening so that the shaft cylinder 20 is rotatably connected to the bracket 60.

[0100] Optionally, the slideway includes a first sliding section 211 and a second sliding section 212. The first sliding section 211 is located at the end of the chute 21 facing the sleeve 31, and the second sliding section 212 is connected to the first sliding section 211. Among them, the angle of the spiral angle of the first sliding section 211 is smaller than the angle of the spiral angle of the second sliding section 212.

[0101] In this way, since the inside of the refrigeration device is in a low-temperature environment for a long time, due to the effect of the condensation phenomenon, there will be a certain adhesion force on the internal items, making it difficult to move. By setting the spiral angle of the first sliding section 211 to be smaller than the spiral angle of the second sliding section 212, when the connecting rod 33 moves along the first sliding section 211, compared with the connecting rod 33 sliding along the second sliding section 212, the connecting rod 33 moves a smaller distance when the handle 50 rotates by the same angle. That is to say, the contraction distance of the sleeve 31 is shorter. When the user rotates the handle 50 at the beginning, the sleeve 31 can have a larger acceleration, and the user can drive the telescopic movement of the sleeve 31 with a smaller force, improving the operation convenience of the user. In addition, when the sleeve 31 is extending, when the connecting rod 33 moves from the second sliding section 212 to the first sliding section 211, the extending speed of the sleeve 31 can be slowed down, reminding the user that the sleeve 31 is about to reach the extended position, and avoiding problems such as the connecting rod 33 hitting the end of the chute 21 and causing the connecting rod 33 to break or the chute 21 to be damaged due to the user rotating the handle 50 too fast or the elastic member 40 driving the sleeve 31 to extend automatically too fast.

[0102] Optionally, the slideway further includes: a third sliding section 213, the third sliding section 213 is located at the end of the chute 21 away from the sleeve 31, and the third sliding section 213 is connected to the second sliding section 212. Among them, the angle of the spiral angle of the third sliding section 213 is smaller than the angle of the spiral angle of the second sliding section 212.

[0103] In this way, by setting the spiral angle of the third sliding section 213 to be smaller than that of the second sliding section 212, when the connecting rod 33 moves along the third sliding section 213, compared with when the connecting rod 33 slides along the second sliding section 212, for the same angle of rotation of the handle 50, the moving distance of the connecting rod 33 is smaller, that is to say, the moving distance of the sleeve 31 is shorter. When the sleeve 31 is contracting, the contraction speed of the sleeve 31 can be slowed down, reminding the user that the contraction position is about to be reached, and avoiding the problem that the connecting rod 33 hits the end of the sliding groove 21 due to the user rotating the handle 50 too fast, resulting in the breakage of the connecting rod 33 or the damage of the sliding groove 21. When the sleeve 31 is extending, the sleeve 31 can have a greater acceleration, which is convenient for driving the movement of the sleeve 31. Even when the driving force of the elastic member 40 is continuously decreasing, the connecting rod 33 can slide to the first sliding section 211 under the action of the elastic force of the elastic member 40, so that the sleeve 31 extends a sufficient distance.

[0104] Optionally, the shaft cylinder 20 is made of a transparent material.

[0105] In this way, by making the shaft cylinder 20 of a transparent material, the user can clearly see the relative position of the connecting rod 33 and the sliding groove 21, and then intuitively judge whether the sleeve 31 is in the extended position or the contracted position, avoiding the situation that the user makes a wrong operation because they cannot intuitively see the position of the connecting rod 33 relative to the sliding groove 21.

[0109] In this way, by providing the support ribs 71 on the inner container 70, the support ribs 71 can support the shelf 10. By providing the fixing holes and adapting the fixing holes to the telescopic assembly 30, when the telescopic assembly 30 extends the shelf 10, the telescopic assembly 30 extends into the fixing holes of the corresponding side wall, and the position of the shelf 10 can be limited, and further the position of the shelf 10 relative to the inner container 70 can be limited.
