Description

Refrigerator {Refrigerator}

The present invention relates to a refrigerator, and more particularly, to a refrigerator having a drawer-type storage assembly therein.

In general, a refrigerator is a home appliance capable of storing food at a low temperature in an internal storage space shielded by a door. To this end, the refrigerator is configured to cool the inside of the storage space using cool air generated through heat exchange with a refrigerant circulating in the refrigerating cycle, thereby storing stored food in an optimal state.

In recent years, it has been gradually becoming larger and multi-functional according to the trend of changing dietary life and upgrading of products. In addition, for the convenience of users, various structures have been developed to efficiently use the internal space of the refrigerator. For example, there is a structure in which a storage box for storing fresh food such as fruit is placed separately inside the refrigerator and the upper part of the storage box is covered with a shelf made of a transparent material so that the user can observe the inside of the storage box. At this time, various products may be placed on top of the storage box.

The upper shelf of the box is made of glass, and a part fixing the edge of the transparent shelf is made of an injection-molded material. However, in order to wrap and fix the edge of the transparent shelf made of glass material with injection molding, a method such as insert injection must be used, which not only increases manufacturing cost, but also reduces the aesthetics of the box because the part wrapped with injection molding is covered by injection molding. There is also a problem.

In addition, when a plurality of transparent shelves are disposed inside the refrigerator in a structure that extends to each other, the upper surfaces of the shelves cannot be connected in parallel to each other because the injection molding material surrounding the edges of the transparent shelves protrudes. Accordingly, when storage is placed on top of the shelves, the storage is tilted to one side due to the protruding injection molding material, and there is a problem in that the storage is interfered with during movement.

To solve this problem, a method of bonding the bottom of the transparent shelf to the frame was developed instead of covering the edge of the transparent shelf with injection molding. For example, Korean Patent Registration No. 10-1507411 (Prior Art 1) discloses a technique of placing a locking protrusion at the bottom of a glass shelf and injecting an adhesive through an injection hole of the holding protrusion, and US Patent Registration 4,582,738 (Prior Art 2) discloses a method of bonding a glass sheet by injecting an adhesive through a hole in a leg.

However, these prior arts are not easy to manufacture because an injection hole must be molded in the frame to inject the adhesive into the shelf and the adhesive must be accurately injected through the injection hole. In addition, in the prior art, UV adhesive (Light Cure Adhesive) is used for bonding the shelf, so a separate ultraviolet irradiation facility is required, and thus manufacturing cost increases.

In addition, in the process of injecting the adhesive, the adhesive may leak between the shelf and the frame, which deteriorates the quality of the shelf.

Republic of Korea Patent Registration No. 10-1507411 (Prior Art 1) US registered patent 4,582,738 (prior art 2)

When moving from to the connection guide part, the second shelf may overlap the first shelf.

In addition, the second attachment portion may include main attachment grooves extending along the longitudinal direction of the second shelf body disposed on both sides of the second shelf frame. In addition, an auxiliary adhesive groove may be formed parallel to the main adhesive groove, and the auxiliary adhesive groove may be disposed outside the main adhesive groove.

Further, the main bonding groove may have a wider left and right width than the auxiliary bonding groove, and the auxiliary bonding groove may have a deeper depression than the main bonding groove.

In addition, a guide fence may protrude from an upper surface of the second shelf body, and the guide fence may extend in a direction parallel to the second attachment part. At this time, the guide fence surrounds the circumferential surface of the second top plate and may be disposed closer to the outer side of the first shelf body than the auxiliary bonding groove.

The first front body is provided with a cover covering the front circumferential surface of the first top plate, and the upper surface of the first shelf and the upper surface of the second shelf in a state in which the first shelf and the second shelf are spread out. And upper surfaces of the cover part may form the same plane as each other.

As discussed above, the refrigerator according to the present invention has the following effects.

In the present invention, the surface of the shelf frame constituting the shelf is recessed with an adhesive portion, and a top plate made of a transparent material may be directly adhered to the shelf frame while covering the adhesive portion. Accordingly, since the shelf frame does not cover the edge of the top plate, the entire upper surface of the top plate can be exposed, and the aesthetics of the shelf can be improved.

At this time, since the adhesive is injected into the shelf frame through the adhesive portion that is open upwards without a complex structured injection hole, the adhesive injection operation can be easily performed.

In addition, the injection molding material does not protrude between the first shelf and the second shelf, which are spread out to each other, and the upper surfaces of the two shelves form the same plane. Accordingly, even if the stored items are placed on the shelf, the stored items do not tilt and there is no part that gets stuck when moving the stored items, so the usability of the refrigerator is improved.

In addition, in the shelf of the present invention, a plurality of adhesive grooves are arranged side by side along the longitudinal direction of the shelf frame. Since the adhesive supplied to the upper surface of the shelf frame is injected into the plurality of adhesive grooves, the adhesive force between the shelf frame and the top plate can be increased. In addition, since the adhesive can be sequentially injected into the plurality of adhesive grooves, the adhesive does not leak out of the shelf frame. Accordingly, the shelf assembly quality of the refrigerator may be improved, and the aesthetics of the shelf may also be improved.

In addition, the adhesive portion formed on the shelf frame may not penetrate the shelf frame, but may be formed in a recessed structure on the upper surface of the shelf frame. Accordingly, the structure of a mold for injection molding the shelf frame can be simplified and the manufacturing cost can be reduced.

Meanwhile, in the present invention, when the first shelf and the second shelf serving as a cover of the storage assembly overlap each other, the storage space is opened upward to increase the height at which objects can be stored. At the same time, the storage drawer itself provided with the storage space may be drawn forward. Accordingly, the user can not only store tall objects, but also can take out objects without interfering with other parts inside the refrigerator when the storage drawer is drawn forward, thereby improving usability.
