Description

Technical Field

[0001] The invention relates to a refrigeration device with an automatic pushing-out function. Background Art

[0002] The shelves are important parts of the refrigeration device. The function of the shelves is to divide the internal space of the refrigerator into multiple small spaces so that items can be stored on these shelves. At present, the shelves in the existing wine cabinets on the market need to be pulled out manually, and after storing and taking out the red wine, the shelves need to be manually pushed into the wine cabinet.

[0003] Since the process of pushing out or retracting the shelves depends on the external force and the cooperation of the shelf's own slide rails, when the external force is unbalanced, it is easy to cause an unstable sliding process and shaking of objects. In addition, during the operation, the user can only determine whether the shelf is pushed out or retracted into place based on his or her own feeling, which brings a poor user experience.

[0004] Based on this, the present invention provides a refrigeration device with an automatic ejection function. Summary of the invention

[0005] In view of the defects of the prior art, the present invention provides a refrigeration device with an automatic ejection function, which can realize the automatic ejection of shelves and has a compact structure and strong practicality.

[0039] The inner cavity of the cabinet 10 is used as the main storage space, which has a front opening and a door body arranged on the cabinet 10 and capable of covering the front opening. The shelves are distributed in the inner cavity of the cabinet 10 from top to bottom, such as Figure 1 As shown, a plurality of shelves are provided in the cabinet 10, one of which is an automatic shelf 30, which can be automatically pushed out or retracted. In other examples, the number of automatic shelves 30 can be selected according to needs.

[0040] The automatic shelf 30 in this example is set inside the cabinet 10 through the support 20. The support 20 is preferably assembled on the cabinet 10 by means of, for example, snap-on connection. The support 20 includes a bottom wall plate 21, two side wall plates 22 and a partition plate 23. The two side wall plates 22 are used to connect with the cabinet 10. The bottom wall plate 21 and the two side wall plates 22 are fixed to support the automatic shelf 30. The partition plate 23 is located between the two side wall plates 22 to divide the space above the bottom wall plate 21 to form an area for accommodating the automatic shelf 30 and an area for the driving component 40.

[0041] The sliding component 50 is used to provide guidance for the extension and retraction of the automatic shelf 30. In this example, two groups of sliding components 50 are provided to cooperate in providing support and guidance. The sliding component 50 includes a first track 51, a blocking member 52, a first sliding member 53, a second track 54, and a second sliding member 55.

[0042] like Figure 3 As shown, the first track 51 is recessed downward to form a first slide groove 511, the first sliding member 53 is located in the first slide groove 511 and can slide along the first slide groove 511, and the blocking member 52 is arranged in front of the first track 51, specifically near the middle of the support 20, as shown in FIG. Figure 8 As shown, the first sliding member 53 includes an upper connecting seat 531 and a rear roller 532. The rear roller 532 is rotatably disposed below the automatic shelf 30 through the upper connecting seat 531. The rear roller 532 is disposed in the first sliding groove 511 and can rotate forward or backward in the first sliding groove 511.

[0043] The second track 54 is arranged below the automatic shelf 30, preferably directly in front of the first sliding member 53. The second track 54 is a second slide groove formed by an upward depression. The second sliding member 55 is located in the second slide groove and can slide along the second slide groove. The second sliding member 55 includes a lower connecting seat 551 and a front roller 552. The front roller 552 is rotatably arranged on the support 20 through the lower connecting seat 551. The front roller 552 is arranged in the second slide groove and can rotate when the second slide groove (shelf) moves forward or backward.

[0044] Specifically, the front roller 552 is disposed directly in front of the rear roller 532 .

[0045] In this example, the sliding cooperation between the first track 51 and the first sliding member 53, and the sliding cooperation between the second track 54 and the second sliding member 55 form a mutual restraint effect, thereby improving the stability of the automatic shelf 30 during the push-out or retraction process and facilitating the driving of the driving component 40.

[0046] The buffer component 60 can provide buffering when the shelf is automatically pushed to the front or automatically retracted to the rear, so as to prevent the items on the shelf from shaking. Figure 6 As shown, the buffer component 60 includes a front elastic member 61, a rear elastic member 62, a front buffer member 63 and a rear buffer member 64. The front elastic member 61 is arranged at the front side of the blocking member 52, the rear elastic member 62 is arranged at the rear side of the blocking member 52, the front buffer member 63 is arranged below the shelf and is located behind the blocking member 52. When the automatic shelf 30 is pushed out to the front, the front buffer member 63 abuts against the rear elastic member 62. The rear buffer member 64 is arranged below the shelf and is located in front of the blocking member 52. When the automatic shelf 30 is retracted to the rearmost, the rear buffer member 64 abuts against the front elastic member 61.

[0047] The front elastic member 61 and the rear elastic member 62 may be springs.

[0048] The driving component 40 is disposed on the support 20 and acts on the automatic shelf 30 so that the automatic shelf 30 passes through the front opening of the cabinet 10 and performs automatic pushing out and retracting actions, such as Figure 3 , Figure 4 As shown, the driving component 40 includes a motor 41, a gear transmission group 42, a transmission chain / belt 43, and a connecting member 44. The motor 41 is arranged on the support 20, the gear transmission group 42 is arranged at the output end of the motor 41, the transmission chain / belt 43 is arranged on the support 20 through two synchronous wheels 45 and is driven by the motor 41 to drive the gear transmission group 42, the connecting member 44 is arranged on the transmission chain / belt 43 and is connected to the automatic shelf 30, the rotation of the motor 41 drives the gear transmission group 42 to drive the transmission chain / belt 43 to rotate back and forth, so as to realize the forward extension or backward retraction of the automatic shelf 30.

[0049] The connecting member 44 preferably adopts the cooperation of the connecting rod 441 and the clamping seat 442 to facilitate assembly;

[0050] Specifically, a guide groove is provided on the partition plate 23 , and the connecting rod 441 can pass through the guide groove to be matched and connected with the clamping seat 442 .
