Description

Deflection device of the door for refrigerator

The present invention relates to a refrigerator, and more particularly, to an apparatus for preventing sag of a refrigerator door, which can prevent a phenomenon in which a body is deformed by a weight load of the door.

In general, a refrigerator is a long-term preservation of food in a low temperature state by heat exchange by converting the internal air into a cold by repeated cycles of refrigerant compression-condensation-expansion-evaporation, Figure 1 shows an example of such a conventional refrigerator will be.

That is, the main body 1 of the refrigerator usually has a refrigerator compartment 3 for keeping food at a temperature of 0 to 5 ° C. so as not to freeze, and a freezer compartment for freezing and storing relatively perishable foods such as meat and fish products. 2) are respectively provided separately, the inlet of the freezer compartment and the freezer compartment is provided with a door (4) for opening and closing each chamber, the door is hinged to one end of the main body (1).

Each door 4 of the freezing compartment 2 and the refrigerating compartment 3 is hinged to the main body 1 so that one end of the freezing compartment 2 and the refrigerating compartment 3 is fixed by the weight of the door 4 itself and the weight of food stored inside the door. The concentrated load acts on the one side as shown in FIG. 2 or the deformation of the main body 1 such as the main body 1 is distorted.

In particular, since the deformation of the main body 1 and the position of the door 4 are changed as described above, a gap is generated between the inlet of the freezer compartment 2 and the refrigerating compartment 3 and the door 4, and thus cold air is leaked to the outside. Or there is a problem in reducing the refrigeration efficiency because the outside hot air is introduced into the inside.

In order to compensate for this, by dividing the center of the door (4) to the center and hinged to both ends of the main body 1, respectively, to minimize the weight load applied to the main body 1, the door 4 is fixed A method of laying a separate reinforcing material on the main body 1 or increasing the outer wall thickness of the main body 1 was used.

However, the former structure is suitable for a large capacity, the disadvantage of reducing the male and female space when applied to a small refrigerator, the latter structure has the disadvantage that the production cost increases because the additional reinforcement or to increase the outer wall.

The present invention has been made in view of the above-described conventional problems, the door for storing food at the inlet of the freezer compartment and the refrigerating compartment is hinged to one end of the main body, resilient to emerge in the vertical direction at the bottom of the door Installed the rollers and guide members fixed to the main body to guide the rollers respectively to support the free end side of the door due to the deflection prevention device of the refrigerator door that can prevent the weight load is biased to the fixed end of the main body To provide.

12: stopping plate 20: guide member

41: groove 42: hanging piece

It demonstrates with reference to FIG.

That is, the roller 10 is elastically installed at the lower end of the door 4 installed at the inlet of the refrigerating chamber 3 of the refrigerator body 1 so as to be protruded in the vertical direction, and the lower part of the roller 10 Mounting guide member 20 is provided to guide the contact with the roller.

On the other hand, the groove (41) is formed in the door (4) for the elastic installation of the roller (10), the groove is inserted into the elastic spring (11), and the elastic spring by tightly installing the roller in the lower portion of the elastic spring It is to be settled up and down by the elastic force of the spring.

In addition, the upper end of the roller 10 is formed with a locking plate 12 of a size corresponding to the inner diameter of the groove 41, at least on both sides of the open end so that the locking plate is not separated to the opening of the groove 41. The locking plate 42 is formed.

In the present invention configured as described above, when the door 4 is opened as shown in FIG. 4, one end of the door 4 is pulled from the main body 1 when the handle (not shown) is pulled by artificial force in the same manner as the conventional method. When the pulley 4 is pulled outward, the roller 10 installed at the bottom of the door is pushed up to the curved top surface of the guide member 20 to push the elastic spring 11 into a compressed state. When the elastic spring 11, which has been compressed while passing through the upper dead surface, is tensioned by the restoring force and continues to apply the force, the roller 10 is released from the guide member 20 and the door 4 is completely opened.

On the other hand, when the door 4 is closed, the above process is made in the reverse order, and the lock 10 prevents the door 4 from being opened by the top surface unless the artificial force is applied when the roller 10 reaches the final position through the top surface. The vertical load of the door 4 is offset by the repulsive force of the elastic spring 11, and as a result, the door 4 is supported.

When the roller 10 is being guided on the guide member 20, the door 10 is supported by the repulsive force (tensile force) of the elastic spring 11 and the roller 10 is closed even when the door 4 is closed. ) Is located on the guide member 20 to cancel the vertical load of the door 4 by the repulsive force of the elastic spring (11).

That is, since both the fixed end and the free end of the door 4 are supported, the main body 1 can be minimized to one side or deformed, thereby extending the life of the product.
