Description

Technical Field

[0001] The invention relates to a refrigeration device capable of automatically pushing out the device. 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 capable of performing an automatic ejection function. Summary of the invention

[0035] A refrigeration device (wine cabinet) capable of automatically pushing out a wine, comprises a refrigeration cabinet body 10, an active sliding component 20, a driven sliding component 30, a refrigeration rack 40 and a driving component 50.

[0036] The refrigerating cabinet body 10 has a front opening 11, and the front opening 11 can be closed or opened by a closable door body to form a refrigerated space with a relatively low temperature in the refrigerating cabinet body 10 for storing red wine; the refrigerating shelf 40 is arranged in the refrigerating cabinet body 10 through an active sliding component 20 and a driven sliding component 30, and the driving component 50 acts on the active sliding component 20 to drive the refrigerating shelf 40 to pass through the front opening 11 of the refrigerating cabinet body 10 for automatic extension and retraction.

[0037] The refrigeration cabinet body 10 has a top wall 12, a bottom wall 13 and a side wall 14. The active sliding component 20 is arranged on the bottom wall 13 or on a lower mounting bracket 16 fixed relatively to the bottom wall 13. The driven sliding component 30 is arranged on the top wall 12 or on an upper mounting bracket 15 fixed relatively to the top wall 12. The active sliding component 20 and the driven sliding component 30 correspond to each other up and down to avoid possible sliding of the refrigeration rack 40. Furthermore, two or more driven sliding components 30 may be arranged to better balance the refrigeration rack 40.

[0038] In order to facilitate the process of pushing the refrigerating shelf 40 forward or retracting it backward, it is preferred that the refrigerating shelf 40 does not contact the side wall 14 to minimize the friction phenomenon of pushing forward or retracting it backward. More preferably, the gap between the refrigerating shelf 40 and the side wall 14 is smaller to facilitate more adequate storage and use of the refrigerating shelf 40.

[0039] A vertical main bracket 41 and a plurality of refrigeration brackets 42 are provided on the refrigeration rack 40. A first connecting seat 43 cooperating with the driven sliding component 30 is provided above the main bracket 41, and a second connecting seat 44 cooperating with the active sliding component 20 is provided below the main bracket 41, so as to realize the cooperation between the refrigeration rack 40 and the active sliding component 20 and the driven sliding component 30 respectively.

[0040] The multiple refrigerated racks 42 may be the same or different and can be adapted according to consumer usage, such as flat wine racks, inclined display wine racks, wine glass racks, etc., to store wine and accessories as needed, such as the simultaneous use of multiple different refrigerated racks 42 shown in the figure.

[0041] The active sliding component 20 in this embodiment includes a connecting seat 21 , a main motion guide rail 22 , four first rollers 23 , a buffer guide rail 24 , four second rollers 25 , a front elastic buffer 26 and a rear elastic buffer 27 .

[0042] See also Figure 6 -9, the connecting seat 21 is recessed to form a main motion slide groove 211, and the main motion guide rail 22 is slidably supported and arranged in the main motion slide groove 211 through four first rollers 23, wherein the distribution of the four first rollers 23 is as follows Figure 7 As shown, two first rollers 23 are arranged on the main motion slide 211 through a rotating support (not shown in the figure), specifically at the front end, and the remaining two first rollers 23 are arranged below the main motion guide rail 22 through a rotating support (not shown in the figure), specifically at the rear end. By adopting the roller method, the friction force is greatly reduced, that is, the driving component 50 only needs a smaller power to meet the use, which is conducive to simplifying the structure.

[0043] Specifically, a buffer groove 221 is formed in the main motion guide rail 22, and the buffer guide rail 24 is slidingly supported in the buffer groove 221 through four second rollers 25. The distribution of the four second rollers 25 is the same as that of the four first rollers 23, which will not be repeated here.

[0044] In this embodiment, in the front-to-back direction, the length of the buffer guide rail 24 is less than the length of the main motion guide rail 22. Preferably, the buffer guide rail 24 is stepped, and the buffer chute 221 on the main motion guide rail 22 is also stepped. Figure 7 As shown, the shaking phenomenon caused by the buffer guide rail 24 can be prevented.

[0045] Specifically, the second connecting seat 44 on the refrigerating rack 40 is fixedly connected to the buffer guide rail 24 .

[0046] In order to reduce the influence of the motion inertia generated during the automatic extension and retraction process of the refrigeration rack 40, a front elastic buffer 26 and a rear elastic buffer 27 are provided, wherein the front elastic buffer 26 is provided on the main motion guide rail 22, and the buffer guide rail 24 is provided with a front stopper 241. The buffer guide rail 24 moving forward relative to the main motion guide rail 22 can stretch the front elastic buffer 26 through the front stopper 241; the rear elastic buffer 27 is provided on the main motion guide rail 22, and the buffer guide rail 24 is provided with a rear stopper 242. The buffer guide rail 24 moving backward relative to the main motion guide rail 22 can stretch the rear elastic buffer 27 through the rear stopper 242.

[0047] Furthermore, limit plates 222 are provided on the front and rear sides of the main motion guide rail 22 to limit the range of motion of the buffer guide rail 24; the buffer limit of the movable guide rail in the front and rear directions in this embodiment is a short-distance, elastically tensile, and very low-speed movement process, so that the refrigeration rack 40 stops smoothly.

[0048] See also Fig.10 The driving component 50 is a gear transmission assembly, which includes a driving motor 51, two transmission wheels 52, a synchronous chain / belt 53 and a connecting piece 54. The main motion guide rail 22 is connected to the synchronous chain / belt 53 through the connecting piece 54. Under the action of the driving motor 51, the two transmission wheels 52 rotate to drive the main motion guide rail 22 to move forward or backward synchronously with the synchronous chain / belt 53.

[0049] The driving motor 51 preferably drives the transmission wheel 52 to rotate synchronously in a gear rack manner to drive the synchronous chain / belt 53 to run forward or backward.

[0050] In a single automatic push-out and / or retraction cycle, the speed of the drive motor 51 is adjustable to actively reduce the motion inertia of the refrigerated shelf 40 before it stops, thereby maintaining the overall stability of the device. The control principle is as follows: Fig.11 As shown, a first position switch 55 is provided on the pushing path of the refrigerated shelf 40. The driving motor 51 initially pushes forward at a relatively high speed. After pushing out to trigger the first position switch 55, the driving motor 51 automatically switches to a relatively low speed and continues to push forward to the farthest position, thereby completing the pushing process.

[0051] A second position switch 56 is provided on the retraction path of the refrigerating shelf 40. The driving motor 51 initially retracts backward at a relatively high speed. After retracting to trigger the second position switch 56, the driving motor 51 automatically switches to a relatively low speed and continues to retract backward until it is completely located in the refrigerating cabinet body 10, thereby completing the retraction process.

[0052] When the refrigeration shelf 40 is pushed out to near the farthest end or fully retracted into the refrigeration cabinet 10, the pushing speed is slowed down to prevent the refrigeration shelf 40 from having obvious collisions, achieve a buffering effect to maintain stability, avoid shaking of the red wine, and effectively prevent sudden collisions with objects that may exist in front at a high speed.

[0053] In this embodiment, wireless control can be used to control the operation of the drive motor 51 to push out or retract the refrigeration shelf 40. A specific control method, for example, includes a first wireless module and a second wireless module. The first wireless module and the second wireless module are connected by signal. The first wireless module is arranged in the refrigeration cabinet 10. The first wireless module receives the control signal sent by the first wireless module and converts the control signal into a drive signal to control the forward and reverse rotation of the drive motor to achieve forward pushing or backward retraction.

[0054] The second wireless module is disposed on the refrigerating shelf 40 , and the drive motor 51 can be controlled by manually pressing the switch 60 matched with the second wireless module when the door is opened.

[0055] Although the present invention is disclosed as above with preferred embodiments, it is not intended to limit the scope of the present invention. Any person skilled in the art can make some improvements without departing from the scope of the present invention, that is, all equivalent improvements made according to the present invention should be covered by the scope of the present invention.
