Description

Door opener of refrigerator

The present invention relates to a door opener of a refrigerator, and more particularly, to prevent infants or children from opening the door more than necessary, to suppress the loss of cold air and the increase in power consumption, and to maintain the freshness of the stored food. It relates to a door opening and closing device of the refrigerator.

In general, a home refrigerator is provided with a freezer compartment and a refrigerating compartment, and is installed to be opened and closed by a door.

That is, the refrigerator is divided into freezers and refrigerators so as to be separated and stored in consideration of the characteristics of food to be stored and is opened and closed by a door.

1 shows a typical refrigerator.

As shown, the refrigerator body 10 has a housing shape.

The inside of the main body 10 of the refrigerator is partitioned into a freezer compartment and a refrigerating compartment to be stored in an isolated state in consideration of characteristics of food to be stored.

On the other hand, the main body 10 of the refrigerator is sealed by a pair of doors (or a single door) 20, 30 which seals each storage compartment, and the holding part 21 at a suitable place in front of the doors 20, 30. 31 is disposed.

Therefore, after opening the doors 20 and 30 in the state of holding the holding parts 21 and 31, the food stored in the inside is taken out.

However, the following problems occur in such a general refrigerator.

That is, curious and playful infants and children often open the doors 20 and 30 as a joke, rather than to withdraw food stored in each storage room, and thus the internal cold air is lost. There is a problem that the power consumption is increased and the freshness of the stored food is reduced.

Therefore, the technical problem to be solved by the present invention, that is, the purpose of the present invention is to solve the problems that the door of the refrigerator as in the prior art, it is not identified from the outside for the door to seal each storage compartment of the refrigerator. By providing a lock, it prevents infants and children from opening the door more than necessary, thereby suppressing the loss of cold air and the increase of power consumption, and providing a door opening and closing device of the refrigerator that maintains the freshness of the stored food. It is.

The present invention in order to achieve the above object, the freezing compartment and the refrigerating compartment in the main compartment separated; At least one door opened and closed with respect to the body; Locking means corresponding to the main body and the door, the locking means to maintain the lock state with respect to the main body; And it provides a door opening and closing device of the refrigerator provided as a release means for selectively releasing the locking means.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object will be described in detail.

Figure 2 is a side view showing a refrigerator in which the present invention is installed, Figure 3 is an enlarged cross-sectional view showing a portion "A" of Figure 2, the same parts and members as in the prior art uses the same member number.

In other words, the locking means and the releasing means according to the present invention will be described with reference numerals ″ 40 ″ and ″ 50 ″.

That is, the freezer compartment and the refrigerating compartment will be installed inside the main body 10 of the refrigerator according to the present invention.

In addition, the main body 10 is sealed by at least one or more doors 20 and 30, and the holding parts 21 and 31 are provided in the proper places of the doors 20 and 30 in the same manner as in the prior art. .

However, in the present invention, the main body 10 and the doors 20 and 30 are locking means 40 which always maintain the locked state of the doors 20 and 30 with respect to the main body 10. Is provided, the locking means 40 is selectively released by the release means (50).

As shown in FIG. 3, the locking means 40 includes a locking protrusion 41 integrally protruding from one side of the front surface of the main body 10 and an inner side of the door 20 and 30 corresponding to the locking protrusion 41. It is formed in the inner groove 42 having a guide groove 43, the hook member 44 rotatably arranged in the inner groove 42, and the elastic member 45 holding the hook member 44 in one direction It is provided with).

Preferably, the hook member 44 is preferably provided with a magnetic material.

In addition, the hook member 44 is provided with a non-magnetic material, one side of the magnet (M) is more preferably inserted into the insert.

And, as shown in c of Figure 3, the release means 50 is more preferably provided with a magnet to be operated by a magnetic force on the outside of the door (20) 30 with respect to the hook member (44).

Of course, the magnet M functioning as the release means 50 with respect to the locking means 40 has a strong magnetic force to overcome the elastic restoring force of the elastic member 45 holding the locking member 44. It shall be provided with.

It describes the operation and effect of the present invention configured as described above.

The state shown by the solid line in FIG. 3A shows the state before operation of the present invention.

That is, in this state, the hook member 44 rotatably arranged inside the inner groove 42 has one end of which is held by the locking protrusion 41 by passing through the guide groove 43. 20) 30 may be referred to as a closed state.

In addition, in this state, the hook member 44 is given a force to be pulled in one direction by the elastic force of the elastic member 45 so that the hooking state of the hook member 44 with respect to the engaging projection 41 is maintained. It can be said that the state.

When the food or the like, which is the object of storage, is introduced into the main body 10 in the first state as described above, the outside of the doors 20 and 30 corresponding to the place where the locking projection 41 protrudes. 3b, the magnet M serving as the release means 50 is brought into close contact with each other.

Therefore, the hook member 44 is rotated in the other direction, as shown by the one-point arrow, and tensions the elastic member 45 by the magnetic force of the magnet M, which functions as a release means.

Therefore, the hook member 44 is rotated in the other direction, and the hook member 44 is separated from the locking protrusion 41 so that the doors 20 and 30 can be opened.

Of course, as described above, in order to rotate the hook member 44 by the magnetic force of the magnet, the magnetic force of the magnet will have to be significantly greater than the elastic restoring force of the elastic member 45.

In addition, when the doors 20 and 30 are closed, the magnets of the release means 50 are attached to the outside of the doors 20 and 30 in the reverse order, that is, the elastic members 45 are tensioned. After the doors 20 and 30 are closed in the state, the magnets can be closed by removing the magnets from the doors. However, even when the doors are closed while the magnets M are removed from the doors 20 and 30, the hook member is closed. The inclined surface of the 44 may be slid and rubbed with the inclined surface of the locking protrusion 41, and the hook member 44 may be caught by the locking protrusion 41.

Therefore, the door opener (or lock) of the refrigerator is not exposed from the outside, only the user (or adults) uses a magnet that functions as a key and open and close the door as needed.

The present invention of such a configuration, as in the prior art, curious and playful infants and children to open the door often playfully rather than to draw out the food stored in each storage room to lose the cold air inside, As a result, more power consumption is required and the problem of reducing the freshness of the stored food is actively solved.

Refrigerator to which the present invention is applied, as described above, prevents infants and children from opening the door more than necessary, thereby preventing the loss of cold air and the increase in power consumption, and maintaining the freshness of the stored food. There is this.

Although the present invention has been described as an example of one embodiment shown in the drawings as described above, this is merely exemplary and various modifications and equivalent other embodiments will be possible to those skilled in the art.
