Technical Field

The invention relates to the technical field of refrigeration, in particular to a sliding rail, a drawer and a refrigerator.

Background

A refrigerator is a device for keeping food stored in a storage compartment fresh at a low temperature by supplying low-temperature air to the storage compartment. The existing refrigerator includes a freezing chamber and a refrigerating chamber, and the temperature of the freezing chamber is lower than that of the refrigerating chamber.

In recent years, refrigerators with an ice making function have been more and more popular with consumers. An ice-making unit, which is generally provided in a freezer compartment of a refrigerator, includes an ice-making tray to receive water to make ice cubes; the ice storage box is arranged below the ice making tray and used for containing ice blocks; and the ice maker main body is fixed in the inner container of the freezing chamber.

In the above-described ice-making unit, the ice bank is configured to be pushed in or pulled out of the freezing chamber, and the pushing in and pulling out of the ice bank is performed in synchronization with the pushing in and pulling out of the drawer of the freezing chamber. The disadvantage of this type of design is that when the user only accesses frozen food without the need for ice, the ice bank is pulled out simultaneously each time the freezer drawer is pulled open, and the food in the freezer drawer easily contaminates the ice in the ice bank. In addition, the ice bank is pulled out to accelerate the melting of ice cubes to cause ice adhesion, so that the quality of ice for a user is degraded.

In addition, most of the existing ice banks are of an open structure, and when the ice making unit makes ice in the freezing chamber, the ice banks of the open structure and the storage objects of the freezing chamber are easily interfered with each other, so that ice blocks are polluted.

Conversely, when the movable rail 43 moves from the retracted position toward the extended position, the movable rail 43 moves toward the proximal end of the fixed rail 41, and the movable rail locking member 90 moves together with the movable rail 43 toward the proximal end of the fixed rail 41, wherein the stop protrusion 76 located in the limiting groove 92 of the movable rail locking member 90 moves together with the movable rail locking member 90 toward the proximal end of the fixed rail 41. The bottom of the movable rail locking member 90 slides along the top surface of the cushion block 65 toward the slope 651 at the proximal end thereof, and the movable rail locking member 90 is guided away from the cushion block 65 by the slope 651 at the proximal end of the cushion block 65, and by the height difference between the top surface of the cushion block 65 and the bottom end of the slope 651 and the counterclockwise (or second) force applied by the fourth elastic member 93, the movable rail locking member 90 rotates counterclockwise (or second) around the protrusion 431, the stop protrusion 76 is disengaged from the end of the limiting groove 92, the mutual limiting between the stop protrusion 76 and the distal end of the movable rail 43 is released, and the movable rail 43 can slide toward the proximal end of the fixed rail 41, so as to pull the ice bank 22 out of the bracket 21.

In addition, when the moving rail locking member 90 at the distal end of the moving rail 43 is engaged with the sleeve assembly 60, the push spring link 70 and the latch 80, the first elastic member 73 in the push spring link 70 and/or the second elastic member 81 in the switch 80 can provide the above-mentioned resilience to the first body 71 of the push spring link 70, the distal end of the first body 71 is acted on by the above-mentioned resilience, the first body 71 moves toward the proximal end of the fixed rail 41, so that the stop protrusion 76 on the first body 71 pushes the limit slot 92 of the moving rail locking member 90 toward the proximal end of the window portion 64, the sliding of the moving rail locking member 90 relative to the pad 65 is accelerated, when the moving rail locking member 90 moves to the slope 651, due to the height difference between the top surface of the pad 65 and the bottom end of the slope 651, and the counterclockwise (or second direction) acting force exerted by the fourth elastic member 93, the moving rail locking member 90 rotates counterclockwise (or second direction) around the protrusion 431 in the counterclockwise direction (or second direction), the stop lug 76 is disengaged from the end of the limit groove 92.

In a preferred embodiment, the ramp 651 at the proximal end of the pad 65 is located near the proximal end of the window 64.

In a preferred embodiment, the limiting groove 92 is a comma groove, for example.

In a preferred embodiment, the window portion 64 is, for example, an elongated slot.

By means of the sliding rail 40, when the drawer 100 is pulled out from the refrigerator compartment, the ice storage box 22 is pulled out and pushed in without being synchronous with the pulling out and pushing in of the drawer 100, that is, the drawer 100 can be pulled out to take an object first, when ice needs to be taken, the near end of the ice storage box 22 is pressed, the movable rail 43 drives the far end of the middle rail 42 to trigger the ejector assembly (or the far end of the movable rail 43 triggers the ejector assembly), and then the movable rail 43 is pushed to slide out towards the near end of the fixed rail 41, so as to drive the ice storage box 22 to pop out from the support 21.

In summary, the invention provides a sliding rail, a drawer and a refrigerator, wherein an ice making unit is accommodated in the drawer of the refrigerator, the ice making unit comprises a support and an ice storage box, the sliding rail is arranged between the support and the ice storage box, the sliding rail comprises a fixed rail and a movable rail in sliding fit with the fixed rail, wherein a spring pushing assembly is further arranged in the fixed rail, and the spring pushing assembly can be triggered by pressing the near end of the ice storage box, so that the movable rail slides towards the near end of the fixed rail, and the ice storage box is ejected from the support.

Because the ice-storage box realizes opening and closing through the relative support of independent bullet slide rail that pushes away, with the stroke alternate segregation that opens of freezing drawer, freezing drawer pulls out the back, and the ice-storage box still is in the closed condition, under the prerequisite that does not influence the ice-storage box, realizes the freezing food space maximize of access, and is more convenient. The drawer with the ice making unit solves the problem that ice cubes in an ice storage box are adhered due to the fact that the existing drawer and the ice storage box are pulled or pushed synchronously while the requirement that a user can freely store and take stored objects in the drawer is met.

In addition, the ice storage box is opened by pressing the near end of the ice storage box, so that the user interaction experience is enhanced while the ice taking is realized as required.

The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention.
