Description

Shelf return device of refrigerator

The present invention relates to a shelf returning device of a refrigerator, and more particularly, the user can easily return the drawn shelf to the inside by spring restoring force so that the user can take out the shelf forward to store or withdraw items on the rear side of the shelf. The present invention relates to a shelf returning device for a refrigerator, which improves convenience by automatically returning without pushing the shelf.

In general, shelves are suitably loaded in accordance with the shape and size of things in the refrigerator to efficiently use the space. Especially in the refrigerating chamber, the shelves are divided into multiple stages according to the size of the refrigerator in the upper, middle and lower parts.

This conventional shelf structure is a fixed shelf that simply inserts the plate-shaped shelf into the locking projection protruding on both sides of the inside of the refrigerator refrigerator and seats the article thereon.

Therefore, when loading an object on a conventional fixed shelf such as the need to take out the desired one of the loaded items, if necessary, especially when the object is located behind the inside of the shelf, withdraw the shelf to the front of the refrigerator, or shelf After removing items from the front of the items in order to withdraw the desired items, and after withdrawal of the items that had to be taken out on the shelves in turn, and pushed the shelf inwards was a hassle.

In order to solve this problem, proposed and published Korean Utility Model Registration No. 95-20241, "Rotary shelf of the refrigerator" will be described with reference to FIGS. 1A and 1B.

1A and 1B are a plan view and a front sectional view of a shelf of a conventional refrigerator, in which the inner side of the shelf is cut in a circular shape so that the inclined disc-shaped rotating surface 14 rotates inside the fixed surface 12 of the outer side, A support 12a intersecting in the direction of the center axis of the rotation surface is connected to a lower surface of the fixed surface 12, and a rotation axis 14a protruding upward is formed at an intersection thereof, so that the rotation surface 14 adheres to the center of the rotation surface. ) Is rotatable inside the fixed surface 12.

That is, as the shelves are formed to rotate, the objects loaded on the upper surface of the shelves are also rotated so that the objects located on the rear side of the inside of the store can be easily withdrawn without having to pull the shelves forward.

However, when the size of the container accommodated in the shelf is large, it is placed on the upper side of the rotating surface 14 and is not completely seated so that the rotating surface 14 and the fixing surface 12 are simultaneously covered so as to rotate the rotating surface 14. In this case, there is a problem in that the object is rotated in an arbitrary direction by the rotation of the rotating surface 14 to knock down the objects stored in the adjacent side.

The present invention was devised to solve the above problems of the prior art, the shelf is automatically returned to the inside by the shelf return means after the shelf is pulled out so that the shelf for storing or withdrawing goods loaded on the rear side of the shelf is removed. It is an object of the present invention to provide a shelf returning device of a refrigerator, which is automatically returned after the user pulls out the shelf without automatically pushing the shelf, thereby improving convenience.

The present invention is a shelf of a refrigerator in which both ends of the shelf are fixed to the installation grooves installed on both sides of the inside of the refrigerator compartment of the refrigerator, so as to be sunk back and forth, the guide protrusions protruding in the longitudinal direction in the front and rear directions at both ends of the shelf. At least two roller insertion grooves are formed to allow the roller to be rotatably installed at the lower side of the guide groove, and a guide groove having a “c” shape is formed along the longitudinal direction to allow the guide protrusion to slide correspondingly. Shelf guides fixed to both side walls of the inner box and elastic members having one end elastically fixed to the rear side of the refrigerating compartment to return the shelf to the rear side are installed in the housing and fixed to both bottom surfaces of the rear end of the shelf. It is characterized by consisting of a return means.

Hereinafter, with reference to the accompanying drawings for the configuration and effect of the preferred embodiment of the present invention will be described in more detail.

2 is an exploded perspective view and an enlarged view of a main part of the shelf return device according to the present invention, Figure 3 is a side cross-sectional view of the refrigerator showing a state in which the shelf return device is installed according to the present invention, shown in Figures 2 and 3 As described above, the shelf guides 40 are fixed to the shelf 30 at each side wall of the inner wall 80 formed in the refrigerating chamber R of the refrigerator so that the shelf 30 can be slidably moved forward and backward. Is installed.

The shelf guide 40 is formed long in the front and rear on both sides of the inner box 80, one side of the guide groove 45 of the "c" shaped along the longitudinal direction of the shelf guide 40 is formed in the groove And it is fixed to the inner box (80) by fixing the bolt on the inner wall of the guide groove (45).

The guide groove 45 of the shelf guide 40 has a roller insertion groove 55 corresponding to the size of the roller 50 so that the roller 50 can be installed at the front end, the rear end, and the lower portion of the center. As long as the groove is formed, the roller 50 is rotatably installed inside the roller insertion groove 55.

At this time, the number of the rollers 50 installed in the guide grooves 45 is preferably installed at least two at least in front and rear respectively.

Guides corresponding to the guide grooves 45 on both ends of the shelf 30 so that both ends of the shelf 30 are slidably inserted into the shelf guides 40 respectively provided on both sides of the inner box 80 of the refrigerating chamber R. The protrusion 32 protrudes along the longitudinal direction.

That is, the lower side of the guide protrusion 32 of the shelf 30 is in contact with the roller 50 installed in the guide groove 45 of the shelf guide 40, the front and rear movement of the shelf 30 more smoothly To lose.

When the shelf 30 is pulled out by the user, a return means 60 is installed on the bottom of the rear end of the shelf 30 so that the shelf 30 can be returned to its original position.

The return means 60 is composed of a housing 62 and an elastic member 64, the housing 62 is fixed to the bottom side of the rear end of the shelf 30, respectively, and the elastic inside the housing 62 The member 64 is provided.

The elastic member 64 is provided with a conventional spiral spring that can be returned to its original state when it is increased by a predetermined length, and one end of the elastic member 64 is drawn out to the rear side of the housing 62 to refrigerate the chamber R. It is detachably fitted and fixed to the fixing groove 66 formed in the inner surface 80 of the back.

One end of the elastic member 64 is detachably installed from the fixing groove 66 so that when the user washes the shelf 30, the shelf 30 can be completely removed from the refrigerator.

The present invention having such a configuration is the both ends of the shelf 30 is inserted into the guide groove 45 of the shelf guide 40 installed on both sides of the inner box 80 and slides back and forth flexibly due to the reduced frictional force by the roller 50 It becomes possible.

In addition, after the user pulls the shelf 30 forward by a predetermined interval to store or withdraw the refrigerated object on the shelf 30, the rear side of the shelf 30 does not have to be pushed to the rear side. It is gradually returned to the inside of the refrigerating chamber (R) by the spring restoring force of the elastic member 64 installed in the.

When the load of the refrigerated object stored in the shelf 30 is large and the return of the shelf 30 is not well achieved, when the user gently pushes the shelf 30 to the rear side, the shelf 30 may be resilient. This is returned to the original position.

As described above, the present invention allows the shelf to be automatically returned to the inner side by spring restoring force after the shelf is pulled out, so that the user does not push the shelf after pulling the shelf forward for storage or withdrawal of goods loaded on the rear side of the shelf. Even if it returns automatically, it is effective to improve convenience.
