Further, the drawer assembly further comprises a containing piece which is opened forward and used for containing the lower drawer 1, the middle drawer 2 and the upper drawer 3, two sides of the lower drawer 1, the middle drawer 2 and the upper drawer 3 are in sliding connection with the containing piece, and the containing piece provides supporting force for the lower drawer 1, the middle drawer 2 and the upper drawer 3.
In this embodiment, since the drawer assembly is disposed in the refrigeration device, the accommodating member is the inner container 4 of the refrigeration device, and the lower drawer 1, the middle drawer 2 and the upper drawer 3 are all in the initial state when they are not moved by the forward force and are located in the inner container 4.
The two sides of the lower drawer 1 are connected with the two side walls of the inner container 4 through the sliding rails 5, the sliding rails 5 provide supporting force for the lower drawer 1, and the lower drawer 1 enables the lower drawer 1 to move forwards relative to the inner container 4 through the sliding rails 5.
As described above, the middle drawer 2 is supported and moved forward by the first roller 22 disposed on the first rail 11 of the lower drawer 1; the upper drawer 3 is supported and moved forward by the second roller 31 provided on the second rail 21 of the middle drawer 2.
In addition, the drawer assembly further comprises a middle layer fixing rail 6 and an upper layer fixing rail 7 which are fixed on two sides of the inner container 4, a third roller 23 is arranged at the rear of two sides of the middle layer drawer 2 correspondingly, a fourth roller 32 is arranged at the rear of two sides of the upper layer drawer 3, the middle layer drawer 2 can be supported and moved forward on the middle layer fixing rail 6 through the third roller 23, and the upper layer drawer 3 can be supported and moved forward on the upper layer fixing rail 7 through the fourth roller 32.
The two sides of the middle drawer 2 and the upper drawer 3 are respectively provided with a front group of rollers and a rear group of rollers, the front group of rollers and the rear group of rollers are respectively supported on a track formed by the drawers below the front group of rollers and the rear group of rollers and a track fixed on the side wall of the liner 4, so that the middle drawer 2 and the upper drawer 3 form two groups of four stress points, the weight of the drawers can be uniformly distributed, the supporting force born by each roller is reduced, and the damage rate of the rollers is reduced; in addition, two sets of rollers are provided so that when one of the rollers is damaged, the other set of rollers can continue to support the drawer and move forward.
Further, the first roller 22 is disposed at the front end of the middle drawer 2, the front end of the first rail 11 is formed with a first recess 111, the rear end of the first recess 111 is higher than the first rail 11, and when the lower drawer 1, the middle drawer 2 and the upper drawer 3 are all at the initial positions, the first roller 22 is disposed at the first recess 111.
When the lower drawer 1 is pulled, the first roller 22 is blocked by the rear end of the first recess 111, the middle drawer 2 moves forward along with the lower drawer 1, the third roller 23 rolls forward along the middle fixing rail 6, and the middle drawer 2 is opened. The lower drawer 1 and the middle drawer 2 move forwards together for a certain distance until the rear side surface of the middle drawer 2 abuts against the stop piece 33 at the bottom of the upper drawer 3, the lower drawer 1 and the middle drawer 2 continue to move forwards, the upper drawer 3 is driven to move forwards, and the fourth roller 32 rolls forwards along the upper fixed rail 7, so that the upper drawer 3 is pulled out.
When the third roller 23 moves to the forefront end of the middle-layer fixed rail 6, the third roller 23 cannot move forward any more, the middle-layer drawer 2 reaches the maximum stroke, the lower-layer drawer 1 is connected with the side wall of the inner container 4 through the sliding rail 5, the stroke of the lower-layer drawer 1 is determined by the sliding rail 5 and is not limited by other drawers, and in order to facilitate the opening of the lower-layer drawer 1, the stroke of the sliding rail 5 is generally greater than the length of the whole drawer in the front-back direction, that is, the maximum stroke of the lower-layer drawer 1 is greater than the maximum stroke of the middle-layer drawer 2, after the middle-layer drawer 2 reaches the maximum stroke, the lower-layer drawer 1 continues to pull forward, the first roller 22 cannot continue to stay in the first concave part 111, and passes over the rear end of the first concave part 111, the first roller 22 rolls onto the first rail 11, and as the lower-layer drawer 1 moves forward, the first roller 22 rolls towards the rear end of the first rail 11 until reaching the maximum stroke of the sliding rail 5 or the first roller 22 abuts against the rearmost end of the first rail 11.
The upper drawer 3 is pulled away by a certain distance when the middle drawer 2 reaches the maximum stroke, but the upper drawer 3 can not be moved forward continuously, and the upper drawer 3 can be opened continuously by applying force to the upper drawer 3.
Further, in the horizontal direction, the distance between the stopper 33 and the rear side surface of the upper drawer 3 is greater than half the length of the upper drawer 3 in the front-rear direction. When the middle drawer 2 and the upper drawer 3 are at the initial positions, the rear sides of the middle drawer 2 and the upper drawer 3 are basically flush, the middle drawer 2 can drive the upper drawer 3 to move forward after moving forward until the rear sides are abutted against the stop piece 33, so that the maximum forward opening length of the middle drawer 2 is the distance between the rear sides of the middle drawer 2 and the stop piece 33, and if the distance between the rear sides of the middle drawer 2 and the stop piece 33 is too small, the middle drawer 2 is too small to be opened, so that a user is inconvenient to access objects.
Further, the front ends of the middle-layer fixing rail 6 and the upper-layer fixing rail 7 form a second concave portion 61 and a third concave portion 71 respectively, the rear ends of the second concave portion 61 and the third concave portion 71 are flush with the middle-layer fixing rail 6 and the upper-layer fixing rail 7 respectively, when the middle-layer drawer 2 and the upper-layer drawer 3 move forward to the maximum stroke, the third roller 23 and the fourth roller 32 fall into the second concave portion 61 and the third concave portion 71 respectively, so that the middle-layer drawer 2 and the upper-layer drawer 3 can be positioned, and when the third roller 23 and the fourth roller 32 fall into the second concave portion 61 and the third concave portion 71, the middle-layer drawer 2 and the upper-layer drawer 3 slightly sink, and a user can be prompted that the drawers cannot be opened continuously when the drawers are pulled to the maximum stroke.
It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.
