The flip panel 112 is connected to the fixed panel 111 by a check hinge so that the flip panel 112 forms a support stand at the second position. Wherein, the limit hinge refers to a part which simultaneously meets the hinge requirement and the limit requirement. Of course, in order to allow the flip panel 112 to be switched between the first position and the second position, in addition to the hinge-coupling of the fixed panel 111 and the flip panel 112 using the limit hinge, a limit stopper may be used which is coupled to the hinge to be independent of the hinge. For example, the bottom of the turnover panel 112 is rotatably connected to the bottom of the fixing panel 111, the bottom of the fixing panel 111 has a limiting protrusion extending outward, and the turnover panel 112 is fixed at the second position by the limiting protrusion.

Referring to fig. 1 and 4, a catching groove 13 is formed between the opening side of the flip panel 112 and the fixing panel 111. The structure of the handle groove 13 is simple and beautiful, and the handle groove is formed between the turnover panel 112 and the fixing panel 111, so that the handle groove does not need to be additionally arranged, and the manufacturing cost can be reduced. Where "open side" is relative to the hinged side, in fig. 1-6, the open side of the flip panel 112 refers to the upper side of the flip panel 112, and the hinged side of the flip panel 112 refers to the lower side of the flip panel 112.

In one embodiment, a step surface 1111 is formed at an upper portion of the fixed panel 111, and a catching groove 13 is formed between the flip panel 112 and the step surface 1111. Of course, a step surface may be formed at the opening side of the flip panel 112 corresponding to the surface of the fixing panel 111 to form the catching recess 13 between the fixing panel 111 and the step surface.

According to an embodiment of the present invention, the drawer assembly 1 further comprises an operation switch. The operation switch is switchable between a lock position where the open side is locked to the fixed panel 111 and an unlock position where the flip panel 112 is rotatable with respect to the fixed panel 111. Furthermore, when the operating switch is in the locking position, a pulling force is applied to the position of the buckle handle groove 13, so that the first drawer body 11 can be opened; when the operating switch is in the unlocking position, a pulling force is applied to the position of the buckle groove 13, so that the turning panel 112 can be rotated, and the second drawer body 12 is exposed out of the first drawer panel.

For example, the operation switch may be a lever fixed above the fixed panel. The lever is rotated to a locking position, that is, the lever is rotated to the outer side of the turnover panel 112 (that is, the side close to the user of the refrigerator), and at this time, the drawer assembly is pulled at the position of the handle groove 13, and the first drawer body 11 is opened. The toggle lever is rotated to the unlocked position, i.e., the toggle lever is rotated to a position away from the flip panel 112, and the flip panel 112 is rotated by applying a force to the latch recess 13.

Of course, the above-mentioned operation switch may not be provided, and the turning panel 112 may be rotated by applying a force to the position of the catcher groove 13, and the first drawer body 11 may be opened by applying a force to another position.

Referring to fig. 2, 3, 5 and 6, the outside (i.e., the front side, i.e., the side close to the user) of the second drawer body 12 is open. Furthermore, whether the second drawer body 12 is at the first limit position or the second limit position, the articles in the second drawer body 12 can be taken and placed through the opening. When the second drawer body 12 is in the first limit position, the opening is corresponding to the opening 1112 on the fixing panel 111, and then the article is taken and placed through the opening and the opening 1112. Of course, the second drawer body 12 may also adopt other structures, for example, a second drawer panel may be disposed on one side of the second drawer body 12 facing the fixing panel 111, and then only when the second drawer body 12 is pulled out from the first limit position toward the second limit position, the article in the second drawer body 12 can be taken and placed.

In fig. 1 to 3, the first drawer body 11 is in a pushed-in position (i.e., a closed position); in fig. 4 to 6, the first drawer body 11 is in a position drawn out of the refrigerator (i.e., an open position). Referring to fig. 2 and 3, when the first drawer body 11 is in the closed position, the turnover panel 112 is rotated to access the articles from the second drawer body 12. Referring to fig. 4 to 6, when the first drawer body 11 is in the open position, the articles in the second drawer body 12 can be taken and placed regardless of the position of the second drawer body 12 relative to the first drawer body 11.

For example, in fig. 4, the first drawer body 11 is opened, the second drawer body 12 is located at a first limit position relative to the first drawer body 11, at this time, the opening of the second drawer body 12 is realized through the opening of the first drawer body 11, and further, through the opening above the drawer assembly 1, the article can be taken from the first drawer body 11 and the article can be taken from the second drawer body 12.

For another example, in fig. 5, the first drawer body 11 is opened, and the turnover panel 112 is located at the second position, at this time, the opening of the first drawer body 11 realizes the opening of the second drawer body 12, and further, the upper opening of the drawer assembly 1 allows both the article taking and placing from the first drawer body 11 and the article taking and placing from the second drawer body 12. In addition, since the flip panel 112 is located at the second position, the opening 1112 on the fixing panel 111 can also be used for taking and placing the articles in the second drawer body 12.

For another example, in fig. 6, the first drawer body 11 is open, the flip panel 112 is in the second position, and the second drawer body 12 is in the second limit position. At this time, the articles can be taken from and placed in the first drawer body 11 through the upper opening of the first drawer body 11. In addition, the articles can be taken from the second drawer body 12 through the upper opening or the side opening of the second drawer body 12.

According to the drawer assembly 1 of the present invention, the second drawer body 12 comprises a second drawer panel, which closes the opening 1112 at the first extreme position. In this case, the opening 1112 can be closed by the second drawer panel without providing the turnover panel 112 in the first drawer panel of the first drawer body 11.

In one embodiment, to ensure the hermeticity of the drawer assembly 1, in the second extreme position, the rear side wall 121 of the second drawer body 12 closes the opening 1112. For the refrigerator, the rear side wall 121 of the second drawer body 12 closes the opening 1112, so that cold air of the refrigerator can be prevented from leaking outwards, and the attractiveness of the drawer assembly 1 is ensured.

It should be noted that the second drawer body 12 can rotate between the first limit position and the second limit position in addition to moving in the horizontal direction between the first limit position and the second limit position. That is, when the first drawer body 11 is closed, the second drawer body 12 is turned to open and close itself; when the first drawer body 11 is opened, the second drawer body 12 does not need to be rotated.

According to the embodiment of the present invention, the number of the second drawer bodies 12 along the width direction of the first drawer body 11 is at least one. When the number of the second drawer bodies 12 is plural along the width direction of the first drawer body 11, the accommodating space of the drawer assembly 1 can be divided more flexibly.

According to the embodiment of the present invention, the drawer assembly 1 has a size of the second drawer body 12 smaller than that of the first drawer body 11 along the depth direction of the first drawer body 11. Taking fig. 3 as an example, the second drawer body 12 is drawn out from the first drawer body 11, and the drawing distance is required to be shorter, so as to facilitate the drawing operation of the second drawer body 12.

According to the drawer assembly 1 of the present invention, in the second extreme position, the rear sidewall 121 of the second drawer body 12 closes the opening 1112. Furthermore, when the second drawer body 12 is opened, the cool air in the first drawer body 11 will not leak through the opening 1112, thereby ensuring the sealing performance of the drawer assembly 1 and making the drawer assembly more beautiful when opened.
