[0046] In order to more clearly understand the above aspects, features and advantages of this embodiment, the following further describes this embodiment in detail with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0047] In the following description, many specific details are set forth in order to provide a thorough understanding of the present embodiment. However, the present embodiment may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present embodiment is not limited by the specific embodiments disclosed below.
[0048] It should be understood that, as Figure 1 shown, the drawer 12' is one of the main components of the oven 1', and is often used by users to open and store items. The drawer 12' usually requires a slide rail structure to achieve the sliding of the drawer 12'. Specifically, the current common slide rail structure of the drawer 12', such as Figure 2 and Figure 3 shown, is composed of an inner slide rail 14' and an outer slide rail 18'. The inner slide rail 14' is installed on the drawer 12', and the outer slide rail 18' is installed on the drawer cavity cover plate 16'. Since the slide rail itself can achieve sliding, the drawer 12' can be freely pulled out after installation. However, such a structure is not only relatively expensive, but also when the drawer 12' is opened, the inner slide rail 14' is exposed outside the drawer 12', affecting the aesthetics of the drawer 12'.
[0049] As Figure 4 and Figure 5 shown, the drawer assembly 1 provided by the embodiment of the first aspect of the present invention includes a box body 11 and a drawer 13. The box body 11 is a hollow structure with an opening on one side. The box body 11 includes a bottom plate 112, and a slide bar 12 is provided on the bottom plate 112. At least two slide bars 12 are arranged at intervals along the first direction; a plurality of sliders 14 are arranged on both sides of the drawer 13 along the first direction, and the plurality of sliders 14 are slidably installed on at least two slide bars 12, so that the drawer 13 can slide into and / or out of the box body 11 from the opening 114 of the box body 11; a limiting structure 15 is provided on the box body 11 and is located on both sides of the drawer 13 along the first direction for restricting the movement of the drawer 13 in the first direction.

On the other hand, the slide bar 12 replaces the structure of the rolling groove, and the problem of accumulation of impurities in the rolling groove will not occur. In addition, the limiting structure 15 can play a role in lateral limitation. Among them, the first direction is also the lateral direction of the drawer 13. Through the lateral limitation of the drawer 13 by the limiting structure 15, the slider 14 only provides longitudinal sliding, and the problem of loosening and detachment caused by the long-term lateral force on the roller will not occur.
