[0036] An embodiment of the present invention provides a shelf device and a refrigerator that can flexibly adjust the height and the internal space of the refrigerator.

[0037] The refrigerator 1000 of this embodiment is as follows Figure 1 As shown, it includes a box body 200 and a door body. A storage space is set in the box body 200. A shelf device 100 and a drawer can be set in the storage space. Both the shelf device 100 and the drawer can be used to place items. The shelf device 100 of this embodiment is placed on the drawer.

[0038] In order to clearly express the position and direction described in this embodiment, in this embodiment, the direction of reference gravity is defined as downward, and the opposite direction is upward. The door is located in front of the cabinet 200, and the user can stand in front of the refrigerator 1000 to open the door and operate the items in the storage space. The two sides of the plane formed by the upper and lower front and back are defined as left and right, respectively, and the left and right directions of this embodiment can be interchanged. Generally, the top of the drawer can form a horizontal plane in physics, so that the shelf device 100 will not tilt when placed on the drawer, and the upper surface of the shelf device 100 also forms a horizontal plane.

[0039] The shelf device 100 of this embodiment is as follows: Figures 2 to 6 As shown, it includes a shelf portion 10, a support portion 60 and a shelf portion, the shelf portion 10 includes a plurality of shelf units 101 arranged side by side in sequence in the left and right directions; the support portion 60 is used to support the plurality of shelf units 101, and each shelf unit 101 can be detachably connected to the support portion 60; a group of shelf portions are symmetrically arranged on the left and right sides of the support portion 60, and the shelf portion includes a base 20, a support frame 40, a rotating support rod 30 and an adjusting support rod 50, one end of the rotating support rod 30 is hinged to the base 20, and the other end is hinged to the support frame 40, a plurality of adjusting slots 24 are arranged on the base 20 and / or the support frame 40, the adjusting support rod 50 is connected between the base 20 and the support frame 40, and to any connection between the plurality of adjusting slots 24, the left side of the support portion 60 is connected to the support frame 40 on the left, and the right side of the support portion 60 is connected to the support frame 40 on the right.

[0040] The upper surface of the shelf portion 10 is used to place items, the support portion 60 is used to support the shelf portion 10, the shelf portion is used to support the support portion 60, the base 20 of the support portion 60 is placed on the drawer, and the support portion 60 is supported by the shelf portions on the left and right sides. Such a shelf device 100 does not need to be suspended, and there is no need to pre-install a suspension structure on the inner tank of the refrigerator 1000, and it only needs to be placed on the drawer.

[0041] The base 20, the support frame 40, the rotating support rod 30 and the adjusting support rod 50 together constitute a four-bar linkage. By adjusting the angle between adjacent links, the distance between the base 20 and the support frame 40 can be adjusted. That is, when the adjusting support rod 50 switches the adjusting slot 24, the distance between the shelf portion 10 and the base 20 changes. Multiple adjusting slots 24 correspond to multiple height adjustment gears.

[0042] At the hinged positions of the various parts, larger holes and rotating shafts can be provided on the base 20 and the support frame 40, for example Figure 4 As shown, the rotation groove 21 provided on the base 20 accommodates the rotation of the rotation support rod 30 therein, and other parts at the hinged positions must also reserve sufficient space to accommodate the rotation.

[0043] The detachable connection between the shelf unit 101 and the support portion 60 can be placed naturally on the support portion 60, or can be fixed by a snap connection. In this embodiment, Figure 3 As shown, the support portion 60 includes a front support rod 61 and a rear support rod 62, both of which extend in the left-right direction, and both of which are connected to the support frame 40. The shelf unit 101 includes a front support groove 121 and a rear support groove 131, and the front support rod 61 is inserted into the front support groove 121 of each shelf unit 101, and the rear support rod 62 is inserted into the rear support groove 131.

[0044] The rear support rod 62 further includes connecting ends 621 disposed at its left and right ends, the left connecting end 621 is slidably connected to the left support frame 40, and the right connecting end 621 is slidably connected to the right support frame 40, the shelf unit 101 includes a connecting shelf body 11 and a rear connecting member 13, the rear connecting member 13 is slidably connected to the shelf body 11, and a rear supporting groove 131 is provided on the rear connecting member 13;

[0045] When the rear support rod 62 moves backward, the rear connecting member 13 moves backward while being always connected to the shelf body 11. Therefore, the shelf unit 101 of this embodiment can have three movement modes in total, the first is to move up and down, the second is to stretch in the front and back directions, and the third is to select to move out part of the partition unit. More movement modes and adjustment modes increase the space for users to choose.

[0046] Furthermore, the shelf unit 101 further includes a front connecting member 12, which is slidably connected to the shelf body 11, and a front supporting groove 121 is provided on the front connecting member 12;

[0047] When the rear support rod 62 moves backward, the rear connecting member 13 moves backward relative to the shelf body 11, and the shelf body 11 moves backward relative to the front connecting member 12, while the front connecting member 12 and the rear connecting member 13 are always connected to the shelf body 11. Figure 7 As shown, a front groove 120 can be set in the front connecting member 12, and a rear groove 130 can be set in the rear connecting member 13. The shelf body 11 can be inserted into the front groove 120 and the rear groove 130, and move back and forth in the front groove 120 and the rear groove 130. In addition, a locking structure can be set in the connection between the front groove 120 and the rear groove 130 and the shelf body 11 to ensure that the movement will not be disengaged.

[0048] Furthermore, the opening directions of the front support groove 121 and the rear support groove 131 are both downward, and the shelf unit 101 is placed on the support portion 60 from top to bottom until the front support rod 61 is inserted into the front support groove 121 and the rear support rod 62 is inserted into the rear support groove 131. The structure of taking up and down is convenient for disassembly.

[0049] In addition, the support frame 40 and / or the connecting end 621 includes a plurality of slots 622 arranged in sequence along the front-to-back direction. Figure 3 and 4 As shown, the connecting end 621 is limited by the clamping slot 622 during the sliding process in the front-back direction. The clamping slot 622 defines several gears, so that the shelf unit 101 stops when it is stretched to a certain position and will not slide arbitrarily.

[0050] The upper end of the rotating support rod 30 is hinged to the support frame 40, and a plurality of adjustment slots 24 are provided on the base 20 along the front-to-back direction, and the lower end of the rotating support rod 30 is inserted into the adjustment slot 24. In this embodiment, the first state is set to be the state where the shelf unit 101 is at the highest position, and the second state is the state where the shelf unit 101 is at other lower positions. Figure 2 and 4 As shown, the second state is Figure 5 and 6 As shown in the figure, in the first state, the angles between the rotating support rod 30 and the adjusting support rod 50 and the base 20 are both about 90°. When switching from the first state to the second state, the adjusting support rods 50 on both sides move backwards, and the rotating support rod 30 also tilts backwards until it bends to Figure 6 The angle shown is then adjusted and the support rod 50 is snapped into the new adjustment slot 24 .

[0051] Furthermore, the shelf portion further includes a first support leg 31 and a second support leg 51, and the base 20 is provided with a plurality of first support slots 22 and a plurality of second support slots 23. One end of the first support leg 31 is hinged to the rotation support rod 30, and the other end is selectively inserted into the first support slot 22. One end of the second support leg 51 is hinged to the adjustment support rod 50, and the other end is selectively inserted into the second support slot 23. The first support leg 31 and the second support leg 51 form a triangular structure of force, which plays a role in stable support. A plurality of first support slots 22 and second support slots 23 can be provided, and the number of first support slots 22, second support slots 23 and adjustment slots 24 corresponds to each other.

[0052] Furthermore, the rotating support rod 30 and the adjusting support rod 50 are symmetrical in front and back, and the first supporting leg 31 and the second supporting leg 51 are symmetrical in front and back. The symmetrical structure can make the rotating support rod 30 and the adjusting support rod 50 more evenly stressed and more stably supported.

[0053] In addition, considering the upper and lower symmetry, more adjustment slots, first support slots and second support slots can also be provided on the support frame 40, so that more adjustment gears can be made within a limited space, thereby making the adjustment method of the shelf device 100 more flexible, and a variety of refrigerator 1000 volume methods can be flexibly combined. Therefore, this embodiment provides a new angle of adjustment method of the shelf device 100, and the three variations of the shelf unit 101 meet the usage needs of more users.

[0054] Compared with the commonly used technology, this embodiment has the following beneficial effects:

[0055] The shelf device 100 realizes the up and down movement of the shelf part by adjusting the support rod 50 and cooperating with different adjustment slots 24. Since the forward and backward movement of the support rod is converted into the up and down movement of the shelf part, the height adjustment range can be made very small, and there is no need to set a lot of convex ribs in the up and down directions. In addition, such a structure can independently support multiple shelf units 101, and the placement of each shelf unit 101 does not affect other shelf units 101. In this way, the shelf unit 101 is not placed at the position where the items are high below, and the shelf unit 101 is placed at the position where the items are low below. In this way, items can continue to be placed above the position where the shelf unit 101 is placed, so that the space in the refrigerator 1000 can be used more effectively, more items can be placed in the refrigerator 1000, and the user experience is improved.
