Description

refrigerator {Refrigerator}

The present invention relates to a refrigerator.

BACKGROUND ART In general, a refrigerator is a home appliance that allows food to be stored at a low temperature in an internal storage room that is shielded by a door.

The storage chamber is surrounded by an insulating wall so that the interior of the storage chamber is maintained at a temperature lower than the outside temperature. The storage compartment may be called a refrigerating compartment or a freezing compartment according to the temperature range of the storage compartment.

In order to put an object into or take out the storage room, the user opens the door. In general, the door is rotatably provided in a cabinet, and a gasket is provided between the door and the cabinet.

Accordingly, in a state in which the door closes the storage compartment, the gasket is in close contact between the door and the cabinet to prevent leakage of cool air from the storage compartment. As the adhesion of the gasket increases, the effect of preventing cold air leakage may be increased.

In addition, in order to prevent the cold air from leaking from the storage compartment, the door is formed in a structure in which an insulating material is filled therein. At this time, there is a possibility that the door may be deformed due to the charging process of the insulator or the cold air in the storage room. In order to prevent such deformation of the door, various technologies are being opened.

Prior literature information related to this technology is as follows.

[Prior Literature 1]

1. Publication No. 10-2013-0103993, Publication Date: September 25, 2013, Title of Invention: Reinforcing material for refrigerator door

The [Prior Document 1] relates to a reinforcing material for a refrigerator door that is inserted and installed inside the door to prevent deformation of the refrigerator door. In detail, MDF (Medium Density Fiber board) or PB (Particle Board) formed of a plurality of papers is laminated and attached to the inner surface of the door made of iron plate or the inner surface of the protrusion made of plastic. That is, the door is reinforced by stacking a plurality of papers.

In the [Prior Document 1], paper is used as a reinforcing material, so it is weak in rigidity. Therefore, there is a problem in that there is no effectiveness because the deformation of the door cannot be effectively prevented. In addition, there is a problem in that the reinforcement effect is relatively small because the reinforcing material is not installed in the weak part or has a cross-sectional shape having a relatively small section modulus.

In addition, even when a steel plate having relatively good rigidity is used as a reinforcing material for the door, there is a problem in that it has a complicated structure or is formed very thickly, so that it takes a lot of manufacturing cost and manufacturing time.

It is an object of the present invention to provide a refrigerator that is provided with a door supporter, which is excellent in rigidity and can reduce material costs, inside the door to prevent the door from being deformed due to a foaming process or temperature change.

Another object of the present invention is to provide a refrigerator provided with a door supporter that is formed in a relatively simple structure, is relatively convenient to manufacture, and has reduced material cost by reducing thickness.

The refrigerator of the present invention for solving the above problems includes a cabinet forming an exterior, at least one storage compartment provided inside the cabinet, and at least one rotatably provided on a front surface of the cabinet to open and close the storage compartment A door supporter disposed inside the door is included to prevent deformation of the door and the door, wherein the door supporter includes a flat plate portion that is in close contact with one surface of the door in contact with the storage compartment, and is formed on an edge of the flat portion At least one edge portion and at least one bending portion provided in a bent form by cutting a portion of the flat portion is included.

In particular, since the flat plate portion, the edge portion, and the bending portion are integrally formed, a separate member is not required.

In addition, the bending portion may be bent in the width direction of the refrigerator by cutting the flat portion in the longitudinal direction of the refrigerator. In particular, the bending part may be formed perpendicular to the flat plate part.

In addition, the door supporter may further include a bent portion formed between the bending portion and the flat portion at an acute angle to the flat portion. The bent part naturally connects the bending part and the flat plate part, and it is possible to prevent stress concentration of the door supporter.

The door may include a case having a predetermined internal space, and a filler filled in the case.

In addition, the case may include a first case forming the front exterior of the refrigerator, and a second case disposed on the storage compartment side and coupled to the first case to form the predetermined internal space. The shape of such a case is exemplary, and the case may be provided in various shapes.

The flat portion may be positioned in the predetermined inner space and be coupled to the second case in close contact. That is, the flat portion is closely coupled to the inner surface of the door.

The edge portion includes a first edge portion, a second edge portion, a third edge portion, and a fourth edge portion, the first edge portion and the third edge portion extending in the longitudinal direction of the refrigerator, the second edge portion and the fourth edge portion may extend in the width direction of the refrigerator.

The bending portion may include a first bending portion formed adjacent to the second edge portion and a second bending portion formed adjacent to the fourth edge portion. The number of such bending parts is exemplary and may be provided in various ways.

The first bending part and the second bending part may be cut parallel to the second edge part and the fourth edge part to be bent toward the second edge part and the fourth edge part, respectively.

In the refrigerator according to the embodiment of the present invention, the following effects can be expected.

According to the proposed invention, there is an effect that the refrigerator door is not deformed by heat and external force by providing a door supporter that is prevented from being deformed inside the door.

In detail, by the shape of the door supporter, even when the refrigerator door is affected by heat or the like, it is supported by the door support and is prevented from being contracted or expanded and deformed.

As the refrigerator door is prevented from being deformed as described above, it is possible to provide a user with a sense of trust and to ensure the insulation of the storage compartment, thereby maintaining the temperature of a predetermined storage item stored in the storage compartment.

In addition, the door supporter is formed of a flat flat portion and is in close contact with one side of the door to effectively prevent deformation of the door.

In addition, the door supporter may include a rib portion formed to be bent perpendicularly to the edge of the flat plate portion to prevent the filler filling the inside of the door from leaking to the outside.

In addition, the door supporter is provided with a bending part in which at least a portion of the flat plate is cut to prevent deformation, and a separate member is not required, thereby reducing material costs.

In addition, in the door supporter, a bent portion is formed between the bending portion and the flat portion to facilitate bending, so that relatively little stress is required to form the bending portion.

In addition, stress applied to the bending part by the bending part may be dispersed. Accordingly, the bending portion may not be deformed even when a relatively large load is applied.
