BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a double door, and more particularly, to a gasket separating apparatus of a refrigerator which allows the gaskets which are in close contact with each other when the two doors are closed to be easily separated with the door opening.

1 and 2 are views illustrating a typical French type refrigerator.

As shown in the refrigerator, the refrigerating chamber 1 is positioned above and the freezing chamber 2 is positioned below. In particular, the refrigerating chamber is a French-type refrigerator in which a partition wall separating the interior is not formed.

The refrigerating chamber (2) is a door (3) for opening and closing it is composed of a double-door open structure, the gasket (10) that is in close contact with the refrigerator main body (5) is installed on the circumferential surface of each door (3) do.

In particular, the gasket 11 is installed so that cold air does not leak even in a portion where the doors 3 meet each other. In general, a refrigerator of a French type is provided with a filler on one door so that the gaskets of both doors are in close contact with each other. It has a structure or a fillerless structure in which the gaskets 11 of both doors 3 are in close contact with each other without a filler.

1 and 2 illustrate a pillarless type, in which the gaskets 11 provided on both doors are in close contact with each other when the doors 3 are closed as shown in FIG. 1. ) To seal the gap.

3 is a planar cross-sectional view of the direction 'A' of FIG. 1 showing a state in which the gasket 11 is in close contact with both the doors 3 closed, and the gasket 11 has both doors 3. And a gasket holder 12 provided on side surfaces of the gasket holders 12 and a gasket rubber 13 attached to the gasket holder 12 to be in close contact with each other.

The magnets 14 are respectively installed in the gasket rubber 13 to maintain mutual adhesion.

Particularly, in order to solve the problem that the gasket 11 is opened along the other door when one door 3 is opened, the gasket separating device 15 separating the two gaskets 11 to some extent during the initial opening of the door. ) Is installed.

The gasket separating apparatus 15 is configured to rotate the gasket holder 12 about the hinge portion 16 supported by the door 3, and the gasket holder 12 is rotated around the hinge portion 16. A cam lever 17 is provided which protrudes in the opposite direction. In addition, the cam lever 17 is in contact with the refrigerator main body 5 so that the gasket rubber 13 and the gasket holder 12 rotate about the hinge portion 16 when the door is opened. The cam part 6 which opposes is formed.

Accordingly, in the state in which the door 3 is completely closed, as shown in FIG. 3, the cam portion 18 of the cam lever 17 is seated behind the cam portion 6 of the refrigerator main body 5, and then the one door 3 is closed. Is opened, the cam surface 17 of the cam lever 17 is rotated about the hinge portion 16 while the cam surface 18 of the cam lever 17 passes through the cam portion 6 of the refrigerator main body 5 along with the door. At this time, since the gasket holder 12 also rotates about the hinge portion 16 at the same time, the gasket 11 ′ shown by the dotted line of FIG. 3 is separated from the gasket 11 of the other door 3. Only the door will open.

However, the conventional gasket separating apparatus of the refrigerator made as described above opens one door 3 because the amount of change of the gasket 11 is relatively small compared to the rotation angle of the cam lever 17 generated when the door 3 is opened. When both gaskets 11 are not completely separated, there is a problem that a lifting phenomenon occurs that the other door is slightly opened along one door that is opened.

That is, referring to Figure 3, typically a center of rotation that is, the hinge portion length (H ₂₎ to the length (H _1), the gasket 11 from the hinge portion 16 to the cam lever 17 from 16 Since the design is longer, the amount of change of the gasket 11 is smaller than the amount of change of the cam lever 17 when the door is opened, so that the gasket and the magnet 14 provided in the gasket are not completely separated or mutual attraction works. One door is opened in a state where the other door is also a problem that comes out to some extent.

In addition, since both gaskets 11 are not completely separated in the process of opening the door 3 as described above, each time the door 3 is opened by the interaction of both magnets 14, the gasket is as shown in FIG. The phenomenon in which the rubber 13 is deformed while being deformed to one side is repeatedly generated, and when the refrigerator is used for a long time in such a state, the gasket rubber 13 is damaged and the gasket life is greatly shortened.

Particularly, the gasket 11 installed between the two doors 3 is formed to be long and vertically installed. When the cam lever 17 and the cam part 6 are installed only on the upper side of the door, the gasket separation process is performed. Since the gasket holder 12 is not bent enough to be transmitted to the entire portion of the gasket, the gasket is separated to some extent from the upper side, but the gasket is not separated from the lower side, resulting in a poor reliability of the gasket separating structure.

In addition, when the cam lever 17 and the cam portion 6 are formed at a plurality of positions above and below the door, the overall structure is complicated and expensive.

The present invention has been made to solve the above problems, it is configured to pull the gasket on the hinge side when the door opening and closing to remove the gasket from the mating door more reliably to minimize the interference with the mating door.

In particular, the linear member 61 is zigzagly connected to the gasket holder 51 and the door holder 67 along the length of the gasket assembly 50. Therefore, the roller 65 on the side of the gasket holder 51 and the roller 68 on the side of the door holder 67 are alternately arranged from above in the direction facing each other.

Of course, the gasket holder 51 and the door holder 67 may be provided with a ring through which the linear member 61 passes, instead of the rollers 65 and 68.

The linear member 61 is preferably connected directly behind the portion of the rotation shaft 57 of the gasket holder 51 and the portion where the magnet 55 is located as far as possible.

The gasket actuating mechanism includes a return mechanism for providing a force in a direction in which the gasket assemblies 50 are in close contact with each other, and the linear member 61 so that the gasket 53 is spaced from the mating gasket 53 when the door is opened or closed. It is made of a pulling force generating mechanism (70) for pulling.

The return mechanism is provided on the rotation shaft 57 of the gasket holder 51 to provide a gasket holder 51 with a force opposing the pulling force of the pull force generating mechanism 70 to the gasket holder 51 59). That is, the elastic member 59 provides a force for bringing the gaskets 53 of both doors 35L and 35R into close contact with each other.

The pulling force generating mechanism 70 is formed on one side of the door 35 is composed of a winding motor 71 configured to wind or unwind the linear member 61 according to an external signal.

It is preferable to be provided in the door cap 36 provided in the upper end of the door of the winding motor 71, but is not limited thereto. Of course it is possible.

The winding motor 71 is provided with a winding reel 72 to wind the linear member 61.

The winding motor 71 is configured to be spaced apart from the gasket assembly 50 while being automatically operated according to a signal of a sensor mechanism for detecting door opening and closing. The sensor mechanism is provided at the door handle 38. It is preferable that the touch switch 80 is configured.

The touch switch 80 is a switch used in a general inverter stand or the like. When the switch is made of a metal plate and the user contacts the switch to open or close the door while the voltage is continuously applied, as shown in FIG. Is changed, switch operation takes place.

Of course, in addition to the touch switch 80, a variety of known switches or sensors may be used to determine whether the user intends to open or close the door by holding the door handle 38, such as a button-type switch on the door handle 38. .

On the other hand, between the gasket holder 51 and the door holder 67 is provided with a limit switch 75 for limiting the winding or unwinding operation of the winding motor 71, the limit switch 75 is the gasket assembly It is preferable that the Hall sensor is configured to detect the movement state of the 50.

It is also possible to provide more than one between 67. Of course, in addition to the hall sensor, it can be used in various ways such as light sensor.

Referring to the operation of the first embodiment of the gasket separating apparatus according to the present invention configured as described above are as follows.

In the state in which both doors 35L and 35R of the refrigerator are closed, one gasket 53 is in close contact with the mating gasket 53 by the elastic force acting on the elastic member 59 of the gasket holder 51, and thus, inside the refrigerating chamber 32. To seal.

In this case, as shown in FIG. 9, the gasket holder 51 and the door holder 67 are spaced apart from each other because the linear member 61 is released from the winding reel 72.

In such a state, when the user grabs the handle 38 to open the one door 35R, the touch switch 80 detects this, and the winding motor 71 is in response to the signal of the touch switch 80. The linear member 61 is wound around the winding reel 72 while being driven.

Accordingly, as the linear member 61 is wound around the winding reel 72, the linear member 61 connected to the gasket assembly 50 at regular intervals is pulled to form a nearly straight line as shown in FIG. 10. The assembly 50 is separated while being spaced apart from the relative gasket assembly 50 by a distance ΔX.

At this time, since the limit switch 75 detects a gap between the gasket holder 51 and the door holder 67, when the gasket assembly 50 is pulled more than a predetermined level, the signal of the limit switch 75 is applied. Accordingly, the drive of the winding motor 71 is stopped.

Therefore, the door 35R in a state where the gasket 53 and the magnet 55 that are in close contact with the gasket 53 of the mating door 35L are separated from the gasket 53 and the magnet 55 on the mating doors 35L and 35R side. Is opened along.

On the contrary, even when the door 35R is closed, the user grasps the handle 38 and closes the door, so that the gasket 53 is closed in a state spaced apart from the mating gasket. When releasing the hand, the winding motor 71 is operated in reverse or the operation of the motor is stopped so that one gasket 53 is caused by an elastic force acting on the elastic member 59 of the gasket holder 51. In close contact with each other, the inside of the refrigerating chamber 32 can be sealed.

As described above, when the door 35R is closed and opened, the winding motor 71 is operated according to the signal of the touch switch 80, and the linear members 61 are pulled to separate both gaskets 53 so as to separate the two magnets 55 from each other. It is possible to open and close the door 35R while reducing manpower and minimizing the swept phenomenon between the gaskets 53.

In particular, since the linear member 61 is connected at regular intervals in the up and down direction of the gasket assembly 50 to pull the gasket assembly uniformly and move as a whole, the entire portion of the gasket assembly 50 is moved up and down when the door is opened. Complete separation from the mating gasket assembly 50 results in high reliability of the gasket removal operation.

On the other hand, in the first embodiment of the present invention as described above, although the pull structure generating mechanism 70 and the like has been described in the implementation structure provided in the door cap 36 constituting the upper end of the door (35L, 35R), Therefore, it is possible to install outside the upper end rather than inside the doors 35L and 35R, and it is also possible to install below the doors 35L and 35R which are the "X" parts of FIG.

In addition, when the user grasps the handle 38 of one door and the touch switch 80 recognizes this, the door is not limited to a structure in which only the winding motor 71 of one door is operated, and both doors 35L and 35R are used. It is also possible to configure to operate all of the winding motor 71 of the.

And a pull lever 275 that contacts the cam member 271 when the doors 35L and 35R are opened to move the connecting member 60 while making relative movement.

The cam member 271 may have a cam surface 272 protruding from the refrigerator main body 40 toward the hinge portion 45, and the pull lever 275 may be formed by the cam surface 272 of the cam member 271. The cam surface protrudes in the opposite direction, so that the pulling force generating mechanism 270 is configured to generate a pulling force as the two cam surfaces come into contact with each other when the doors 35L and 35R are opened and closed.

The cam surface of the pull lever 275 is preferably constituted by a roller 276 so as to make a rolling contact with the cam surface 272 of the cam member 271.

In addition, the connecting member 60 is a link member 261 connected to the pull lever 275 and the gasket holder 51 so as to be relatively rotatable, and the gasket holder 51 at the link member 261. It consists of a linear member 262 connected to another portion of the.

Wherein the link member 261 is connected to the upper end of the gasket holder 51, the linear member 262 is the first embodiment described above in the lower end of the gasket holder 51 is not connected to the link member 261 It is preferable to connect in a zigzag manner as in the example.

Referring to the operation of the gasket separation apparatus according to the sixth embodiment of the present invention as follows.

Since the pull lever 275 is in contact with the lower portion of the cam member 271 in the state in which both the doors 35L and 35R of the refrigerator are closed, the elastic lever acting on the elastic member 59 of the gasket holder 51 The side gasket 53 is in close contact with the mating gasket 53 to seal the inside of the refrigerating chamber 32.

In this state, when the user opens one door 35R, the roller 276 of the pull lever 275 moves on the cam surface 272 of the cam member 271. At this time, the maximum pull displacement occurs while the roller 276 passes through the apex of the cam surface 272, and the connecting lever 60 moves in the direction of the hinge portion 45 of the door 35R. ), The gasket holder 51 connected with each other overcomes the elastic force of the elastic member 59 and moves inside the door 35R.

Therefore, the door 35R in a state where the gasket 53 and the magnet 55 that are in close contact with the gasket 53 of the mating door 35L are separated from the gasket 53 and the magnet 55 on the mating doors 35L and 35R side. Is opened along.

On the contrary, even when the door 35R is closed, the roller 276 of the pull lever 275 passes over the cam member 271, so that the gasket 53 is closed immediately before the door 35R is completely closed. It is closed in a state spaced apart from the gasket 53 of 35L to some extent.

As a result, the present embodiment is adapted to separate the gasket 53 from the gasket 53 of the mating door 35L by the interaction of the cam member 271 and the pull lever 275 when the door 35R is closed and opened. The opening and closing operation of the door 35R can be performed while reducing the attraction between the magnets 55 and minimizing the swept phenomenon between the gaskets 53.

In particular, as described in the above-described embodiment, the linear member 262 constituting the connecting member 60 is connected at regular intervals in the vertical direction of the gasket assembly 50 to uniformly pull the gasket assembly 50 as a whole. Since the gasket assembly 50 is completely separated from the mating gasket assembly 50 when the door is opened, the gasket separating operation can be more reliably performed.

In addition, in the present embodiment, since the link member 261 is connected with the linear member 262, even when the linear member 262 is loosened or damaged due to prolonged use, the basic gasket separation operation can be continued.

19 and 20 are views illustrating a gasket separating apparatus according to a sixth embodiment of the present invention. FIG. 19 is a schematic perspective view of one door part, and FIG. 20 is a plan view of a main part of a refrigerator.

As shown here, the gasket separating apparatus of the sixth embodiment of the present invention is similar to the configuration of the fifth embodiment described above, except that the connection member 60 is configured differently.

That is, in the present embodiment, a separate link member 261 is not provided, and the linear member 361 is connected to the pull lever of the pull force generator mechanism.

Since the linear member 361 is connected to the gasket assembly 50 is the same as the connecting method of the first embodiment, a detailed description thereof will be omitted.

Accordingly, as the displacement of the pull lever 275 is changed by the interaction of the pull lever 275 and the cam member 271 when the door is opened and closed, a gasket holder connected to the pull lever 275 and the linear member 361 ( As the 51 is rotated, the gasket assembly 50 can be separated from the mating door side.

The gasket separation apparatus of the refrigerator according to the present invention constructed and operated as described above is configured to pull and separate the gasket from the hinge side of the door instead of the center portion of the door, thereby increasing the displacement at which the gasket is separated, thereby making the gasket more reliable. It can be separated, thereby minimizing interference with the relative door when opening and closing the door, it is easy to open and close the door, there is an advantage that can extend the life of the gasket.

In addition, the present invention is because the gasket separation device is mostly configured inside the door, and the device for separating the gasket by the interference between the door and the refrigerator main body is also located on the hinge side rather than the center part of the door. There is also an advantage that can solve the problem of damage and deterioration of appearance.

In particular, the present invention is configured to pull the gasket formed up and down at the same time in at least two places at the same time, there is an advantage that the gasket is uniformly separated as a whole when opening and closing the door, thereby improving the reliability of the gasket separation operation.
