Description

Door opener of refrigerator

The present invention relates to a door opening device of a refrigerator, and more particularly, to a door opening device of a refrigerator made of a blow mold.

In general, since the outer case of the refrigerator is formed of a steel plate, in order to seal the cold air supplied to the inside of the refrigerator so that the cold air does not leak, the sealing member is attached to the door edge of the refrigerator and the rubber exerts magnetic force on the sealing member. The built-in magnet keeps the sealing member in close contact with the front edge of the iron plate, which is an outer case, so as to prevent leakage of cold air supplied into the interior.

That is, as shown in FIG. 1, the gasket 30, which is a sealing member fixed to the inner edges of the freezer compartment door 10 and the refrigerating compartment door 20, is processed into an iron plate by the magnetic force of the rubber magnet 32 fixed therein. By being attached to the front edge of the cabinet 40, which is an outer case of the refrigerator, it prevents leakage of cold air and blocks the inside of the refrigerator from the outside.

However, since the outer case of the conventional refrigerator made of iron plate material is expensive and difficult to process, a cheaper and convenient alternative material is needed.As such a request, a synthetic resin material such as polypropylene or polyethylene is required. Such a resin was molded by an injection method by air supply, for example, a blow mold method.

However, since the refrigerator outer case molded of the synthetic resin material does not have a means for attaching the sealing member to the outer case as in the prior art, the sealing problem for preventing cold air leakage of the refrigerator has not been solved.

In order to solve the problems in view of the above-described problems, the present invention extends from the upper hinge separately from the support on which the hinge axis protrudes to form a first member, and the latch is fixed to the first member. The second member is rotatably installed around the fixed shaft to form a clasp, and an actuating button is installed to be movable up and down by an elastic body. The interview is formed by forming an operating part which is rotated about its axis of rotation in accordance with the movement of the operation button to form the sea government. A blow made by connecting the chain and the sea government and having a connecting means configured to elastically press the chain government at all times. The door opening device of the refrigerator manufactured by the molding technique was devised.

Hereinafter, with reference to the accompanying drawings a preferred embodiment according to the present invention will be described in more detail.

Figure 2 is a perspective view and enlarged perspective view showing the closed state of the freezer compartment door of the refrigerator having a door opening device according to the present invention, locking and unlocking the refrigerator door to the outer case of the refrigerator made of blow mould (blow mould) It is a device that can be unlocked.

In the accompanying drawings, a gasket 30 ', which is a cold air sealing member without rubber magnets, is attached to the door between the freezer door 10 of the refrigerator and the inner edge of the refrigerator door 20 and the front surface of the main body 50 of the refrigerator. Is installed.

And, the freezing chamber door 10 is provided with a fixing member coupled to a part of the hinge hinged upper hinge 70 is provided with a locking portion 60 to prevent the freezer compartment door 10 is opened, the upper hinge ( On the other side of the freezer compartment door 10 to which the 70 is coupled, the seamer 80 is configured to release the fixing force of the locker 60 so that the freezer compartment door 10 can be opened while being released from the main body 50. In addition, the connecting means is installed between the chain portion 60 and the sea portion 80 so that their operating relationship proceeds organically.

The clasp 60 is formed to extend from the upper hinge 70 to the support 72 apart from the support 72 in which the hinge shaft 74 of the upper hinge 70 protrudes downwardly. A first member 76 and a second member 66 rotatably fixed about the fixed shaft 62 to the freezer door 10 to be latched with the first member 76. It is composed of

On the other hand, the maritime part 80 is an operation button 82 which is a pressing member, an extension 84 extending perpendicular to the side of the operation button 82, and one end of the lower end of the operation button 82 The fixed elastic body 88, the other end of the elastic body 88 is accommodated and the receiving portion 94 is fixed, and the rotating shaft 92 is rotatably formed while being interviewed with the lower end surface of the extension portion 84 It consists of an operating unit 90 is fixed to the freezer compartment door 10 of the refrigerator.

In addition, a flange 86 is formed at an upper portion of the operation button 82 so that the operation button 82 is not released to the outside of the freezer compartment door 10 when the operation button 82 is pressed.

In addition, by connecting the sea level 80 and the chain 60, the operation of the sea 80 is connected to each other by the connecting means to be transmitted to the chain 60.

As shown in the figure, it is preferable to use a tension spring 99, which is an elastic device, but the connecting means may be a rod having a linkage or a bar of a single bar as an inelastic device.

In addition, the door opening device of the refrigerator constituted by the clasp 60, the seam 80 and the tension spring 99 to interconnect them as described above, the freezer door (made of blow mold in the present embodiment) ( 10) Although only illustrated, the freezer door is used as well as the refrigerator compartment door, it is not limited to the refrigerator, but the door is formed so as to close a certain space, including a storage for storage made of blow mold. It will be readily understood that it is applicable to all fields.

In the refrigerator door opening apparatus of the present invention having such a configuration, the user first presses the operation button 82 of the sea top 80 to open the refrigerator door in a state where the freezer door of the refrigerator is closed.

Then, as shown in FIG. 3, the freezing chamber door 10 is opened while the second member 66 of the clasp 60 is released from the first member 76.

That is, when the user presses the operation button 82 downward, the tension of the elastic body 88 is overcome and the operation button 82 is introduced into the upper inside of the freezer compartment door 10.

Therefore, the extension portion 84 extending from the side of the operation button 82 is also lowered at the same time while pressing one end of the operation portion 90.

Therefore, the operation unit 90 is rotated about the fixed rotating shaft 92 to pull the tension spring 99 fixed to the other end.

The first member extending from the upper hinge 70 while being rotated a predetermined angle around the fixed shaft 62 is fixed to the second member 66 is fixed to one end of the tension spring 99 is pulled through such a process The latch engagement with 76 is released.

Therefore, while the freezer compartment door 10 of the refrigerator is opened, the gasket 30 ′ attached to the inner edge thereof is separated from the front surface of the main body 50.

Of course, the operation button 82 of the seam 80 is returned to the original position by the elastic force of the elastic body (88).

On the other hand, if the user closes the freezer compartment door 10 after the completion of a predetermined act, the operation button 82 is always going to go upward and the tension spring 99 is intended to be tensioned, so that the clasp 60 The second member (66) is naturally latched to the first member (76).

As described above, the door opening device of the refrigerator according to the present invention, when the outer case of the refrigerator is made of a blow mold, the user is provided with a refrigerator door and the main body to lock and unlock the refrigerator door If necessary, this device is unlocked to open the door and automatically closed when the door is closed, thereby preventing the leakage of the cold air in the blow mold refrigerator as much as possible, thereby improving the cooling performance of the refrigerator. It will have the effect of improving the freshness of food.
