FIG. 1 shows a preferable embodiment of the drawer assembly structure 10 according to the present invention. The drawer assembly structure 10 according to the present invention is configured for mounting a drawer into a cooling compartment (not shown) of a refrigerator. The drawer assembly structure 10 comprises a drawer body 11 and a slide assembly 12, wherein the drawer body 11 is assembled on the slide assembly 12, such that the drawer body 11 may be pulled out of the cooling compartment.
Referring to FIGs. 2 to 4, the drawer body 11 comprises a front wall 111, a rear wall 112 and two opposite side walls 113, all of which define a storage space 114, and the front wall 111 is covered with a front drawer cover 110. First jaws 1131 and first limiters 1132 are provided on the two side walls 113 of the drawer body 11. The present embodiment is explained with one of the side walls 113 as an example. A bottom of the side wall 113 of the drawer body 11 is recessed towards an interior of the storage space 114, the first jaw 1131 and the first limiter 1132 are provided at the recess of the side wall 113 bottom of the drawer body 11, the first limiter 1132 is provided close to the front wall 111 of the drawer body 11, and the first jaw 1131 is provided close to the rear wall 112 of the drawer body 11.
A location hole 1111 is provided at a bottom of the front wall 111 of the drawer body, and a detent 1133 extends from the bottom of the side wall between the first limiter 1132 and the first jaw 1131.
Referring to FIG. 5, the slide assembly 12 comprises a slide support 121 and a slide rail 122 which are assembled together, wherein the slide support 121 further comprises a U-shaped portion 1211 and a first folded portion 1212 connected therewith fixedly, the first folded portion 1212 is configured for assembling the slide support 121 and the drawer body 11 together, and the U-shaped portion 1211 is configured for assembling the slide support 121 and the slide rail 122 together.
The first folded portion 1212 is provided with a first slot 12121, a first limiting hole 12122, a shifter 12123 and a buckle 12124 corresponding to the shifter 12123. The shifter 12123 is provided close to the first limiting hole 12122 on an inner wall of the first folded portion 1212, and the buckle 12124, corresponding to the shifter 12123, is provided on an outer wall of the first folded portion 1212.
In a process of assembling the drawer body 11 onto the slide support 121, the first jaw 1131 is clipped into the first slot 12121 firstly to prevent a trailing end of the drawer body 11 from warping, and then a leading end of the drawer body 11 is pressed, such that the first limiter 1132 falls into the first limiting hole 12122 gradually, and the buckle 12124 falls into the location hole 1111. When the drawer body 11 is assembled at a set position on the slide support 121, the first jaw 1131 is clipped into the first slot 12121, and the first limiter 1132 is located in the first limiting hole 12122. Preferably, a block piece 12125 is provided between the U-shaped portion 1211 and the first folded portion 1212 close to the first limiting hole 12122, and has a shape fitted with a shape of the first limiter 1132. The first limiting hole 12122 limits the first limiter 1132 in the front and rear direction in cooperation with the block piece 12125. That is, the drawer body 11 is limited in the front and rear direction which refers to herein a direction from the front wall 111 to the rear wall 112 of the drawer body 11. During falling of the leading end of the drawer body 11, the buckle 12124 falls into the location hole 1111, such that the leading end of the drawer body 11 is limited in a vertical direction, and the detent 1133 comes into contact with an edge of the first folded portion 1212. The two detents 1133 at two sides of the drawer body 11 come into contact with the edges of the first folded portions 1212 at respective sides, such that the drawer body 11 is limited in a radial direction thereof.
When the drawer body 11 is disassembled from the slide support 121, only the shifter 12123 is required to be lifted upwards, such that the buckle 12124 is released from the location hole 1111, and at least part of the drawer body 11 is separated from the slide support 121; then the leading end of the drawer body 11 is lifted towards an inclined top, such that the first jaw 1131 is also released from the first slot 12121, and the drawer body 11 may be separated from the slide support 121 completely.
The U-shaped portion 1211 comprises two opposite side walls 12111 and a bottom wall 12112 which connects the two opposite side walls 12111, wherein the bottom wall of the U-shaped portion 1211 is provided with a second slot 12113 and a second limiting hole 12114.
The slide rail 122 is provided with a second limiter 1221 and a second jaw 1222. When the slide support 121 is assembled at a set position on the slide rail 122, the second jaw 1222 is clipped into the second slot 12113, and the second limiter 1221 is located in the second limiting hole 12114, such that the slide support 121 is limited in the front and rear direction. Meanwhile, the slide rail 122 is located between the two side walls 12111 of the U-shaped portion 1211. Preferably, a distance between the two side walls 12111 is matched with a width of the slide rail 122, so as to limit the slide support 121 in a radial direction thereof. Then, a screw 13 penetrates through one of the side walls 12111 of the U-shaped portion 1211 and the slide rail 122 successively, such that the slide support 121 is fixed onto the slide rail 122.
A second folded portion 14 is fixed at a bottom of the slide 122, and may be fixed onto an inner wall (not shown) of the cooling compartment through a screw, thereby fixing the entire slide assembly 12 onto the inner wall of the cooling compartment.
The present invention further provides a refrigerator (not shown), which adopts the drawer assembly structure according to the above-mentioned embodiments, thereby obtaining the beneficial effects thereof; in addition, since no improvement is made to other structures or functions of the refrigerator, descriptions thereof are not repeated here.
It is apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the present embodiments shall be considered as illustrative and not restrictive from any point, and the scope of the present invention is defined by the appended claims rather than the above illustration. Hence, all changes in the meaning and scope of equivalent elements of the claims are included in the present invention.
