In order to make the objects, features and advantages of the embodiments of the present application more comprehensible, the following detailed description of the embodiments of the present application refers to the accompanying drawings.

Fig. 1 is a schematic view of a refrigerator in an embodiment of the present application. Fig. 2 is a partial cross-sectional view of a drawer positioned in a storage compartment in an unexpanded state in accordance with an embodiment of the application. Fig. 3 is a partial cross-sectional view of a drawer positioned in a storage compartment in an expanded state according to an embodiment of the present application.

As shown in fig. 1 to 3, a refrigerator 10 provided in an embodiment of the present application includes a refrigerator main body 100, a pair of support mechanisms 200, and a drawer 300. Wherein the refrigerator main body 100 has a storage chamber 110 therein, and the storage chamber 110 has a pair of opposite side walls 111 therein. A pair of support mechanisms 200 are respectively connected to the respective side walls 111. Both sides of the drawer 300 are supported to the corresponding support mechanisms 200.

In the technical solution provided in the embodiment of the present application, at least one side of the drawer 300 is further provided with a capacity expansion portion 400. The capacity-expanding part 400 communicates with the inside of the drawer 300 and is located under the corresponding supporting mechanism 200. The expansion 400 may move toward the corresponding sidewall 111 to expand the drawer 300.

In the technical solution provided in the embodiment of the present application, the positions where the capacity expansion portion 400 is located include a first position and a second position. The first position is a position where the expansion part 400 is located when the drawer 300 is not expanded. The second position is a position where the expansion part 400 is located when the drawer 300 is expanded, and particularly, a position where the expansion part 400 is located when the drawer 300 is maximally expanded.

In some preferred embodiments, the expansion 400 is adapted to remain in either the first position or the second position.

In the embodiment shown in fig. 2, the expansion 400 is in a first position that is movable toward the side wall 111 in the direction indicated by the arrow in fig. 2 to expand the drawer 300.

Fig. 8 is a schematic view of a drawer provided with a second expansion portion in an unexpanded state according to an embodiment of the present application. Fig. 9 is a cross-sectional view of a drawer provided with a second expansion portion in an expanded state in an embodiment of the present application.

As shown in fig. 8 and 9, the second capacity expansion 420 is slidably coupled with the drawer 300 and can be slid outward with respect to the drawer 300 to expand the volume of the drawer 300.

Fig. 10 is a schematic diagram of a second expansion portion according to an embodiment of the present application.

Referring to fig. 9 and 10, in one or more specific examples, one of the drawer 300 and the second capacity expansion 420 may be provided with a sliding rail 710, and the other of the drawer 300 and the second capacity expansion 420 is provided with a sliding groove 720 matching the sliding rail 710; the second expansion part 420 is slidably connected with the drawer 300 through the sliding groove 720 and the sliding rail 710.

For example, the bottom of the drawer 300 may be provided with an upwardly protruding sliding rail 710, and the bottom of the second capacity-enlarging portion 420 may be provided with a downwardly recessed sliding groove 720. The second expansion part 420 is slidably connected with the drawer 300 through the sliding groove 720 and the sliding rail 710.

In this manner, the second expansion 420 may slide outwardly with respect to the drawer 300 by sliding between the sliding groove 720 and the sliding rail 710 to expand the volume of the drawer 300.

Referring to fig. 9 and 10, in some preferred embodiments, one end of the chute 720 is closed to define an inward limit for the inward sliding of the second expansion 420 relative to the drawer 300.

FIG. 11 is a schematic view of a second spacing assembly according to an embodiment of the present application.

Referring to fig. 8 to 11, a second limiting assembly 800 is further included. The second stop assembly 800 is adapted to define an outward limit position for the second expansion 420 to slide outward relative to the drawer 300.

The limit hook 810 may have a hooking part protruding upward. The hooking part is higher than the upper edge of the expansion port 320 of the drawer 300 in the height direction.

In this way, when the second expansion 420 slides outwards relative to the drawer 300, the hook portion of the limit hook 810 can hook the side wall of the drawer 300 above the expansion 320, so as to define an outward limit position of the second expansion 420 sliding outwards relative to the drawer 300.

In other specific examples, the second stop assembly 800 may further include a stop catch 820. The limiting buckle 820 is fixed on the drawer 300 and located at the outer side of the limiting hook 810, and is adapted to limit the limiting hook 810 and limit the outward limit position of the second expansion part 420 sliding outward relative to the drawer 300.

The limit catch 820 may have a downward catch. The clamping groove is clamped at the upper edge of the second expansion part 420 and is positioned at the outer side of the limit hook 810.

When the clamping groove of the limiting buckle 820 is clamped at the upper edge of the second expansion part 420, the clamping groove is lower than the highest point of the clamping hook part of the limiting hook 810 in the height direction.

As such, when the second expansion 420 slides outwards relative to the drawer 300, the hook portion of the limit hook 810 may hook the limit buckle 820 to limit the outward limit position of the second expansion 420 sliding outwards relative to the drawer 300.

In some preferred embodiments, the limit hooks 810 are bendable, which are adapted to bend when the second expansion 420 slides outwardly relative to the drawer 300 and reaches an outward limit position, allowing the second expansion 420 to slide out of or into the drawer 300.

In this manner, the second capacity expansion 420 and the drawer 300 can be conveniently separated and assembled.

In the present embodiment, the inward limit position of the second expansion 420 is the first position thereof; the outward limit position of the second expansion 420 is its second position.
