It relates to a door opening and closing device of the refrigerator configured to include.

1 is a perspective view showing a refrigerator having a conventional door opening and closing device.

As shown in the refrigerator, a refrigerating chamber 1 is positioned at an upper side and a freezing chamber 2 is positioned at a lower side thereof. 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) has a door (3) for opening and closing the structure of the two-door open type, the circumferential surface of each door (3) is provided with a gasket (10) in close contact with the refrigerator main body (5) so that cold air does not leak out 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.

The refrigerator shown in FIG. 1 shows a pillarless type, and side gaskets 11 provided on both doors are in close contact with each other while the doors 3 are closed to seal the gap between the doors 3.

FIG. 2 is a plan view of an essential part showing a state in which the side gaskets 11 are in close contact with each other when both the doors are closed.

The gasket 11 is provided with a magnetic body 14 to maintain the mutual close force therein, the adhesion of the two gaskets 11 is a problem that the other door is also opened when one door 3 is opened. .

Due to this problem, a door separation structure is provided which separates the open door from the counterpart door so that both the gaskets 11 are separated when the door 3 is initially opened and the door 3 is almost closed.

That is, the hinge mechanism 15 connecting the refrigerator main body 5 and the door 3 includes a hinge link 17 to allow horizontal movement of the door when the door is opened and closed, that is, translational movement. 17 is connected to the hinge bracket 16 and the door 3 installed in the refrigerator main body 5 so as to be relatively rotatable.

The hinge mechanism 15 is provided with an elastic member 18 to provide an elastic force in the direction in which the door 3 is in close contact with the mating door.

And when the door is opened and closed, a spaced apart mechanism is installed to move the open door in a manner that is pushed to each other.

It rotates and the door opens.

On the contrary, even when the door 3 is closed, as shown in FIG. 4, since the roller 26 of the cam contact lever 25 moves along the curved surface of the cam member 21, both gaskets 11 are separated. The door is closed.

Since the door 3 that is opened and closed at the door opening and closing as described above is separated from the counterpart door, the interference between both gaskets 11 is minimized, and the door is opened instantly while the other door is opened when one door is opened, Frequent contact of the gaskets will solve some of the fast wear problems.

However, when the separation mechanism is configured as in the related art, when the door 3 is opened, the hinge link 17 is rotated by a predetermined angle about the door hinge axis 17a and then applied to the elastic force of the elastic member 18. When the hinge link 17 is returned to its original position, the rattling movement is generated in the process of returning the hinge link 17 to the initial position, and the hinge link 17 hits the stopper 19 to generate noise. have.

In addition, when the user opens the door 3 quickly, the door 3 is moved to the path P shown in FIG. 4, and the noise generated at this time is increased.

In addition, when the door 3 is closed, the cam contact lever 25 is returned to its original position through the same path as that of the cam contact lever 25, and the cam contact lever 25 is the closed cam surface of the cam member 21. There is a problem inevitably collide with (21c) to generate noise.

In addition, the door opening and closing device of the conventional refrigerator is difficult to manufacture and assemble the elastic member 18 to return to the hinge link 17 to the original position has a problem that the reliability of the product is lowered.

Referring to Figures 8 to 11 the operation of the door opening and closing apparatus of the refrigerator according to the present invention configured as described above are as follows.

8 is a plan view of an essential part of the door closed state according to the first embodiment of the present invention, Figure 9 is a plan view showing the open state of the door according to the first embodiment of the present invention, Figure 10 is a view of the present invention 11 is a plan view illustrating a closed state of a door according to a first embodiment, and FIG. 11 is a plan view illustrating an operation process of a door opening and closing device when a door is opened and closed in a refrigerator according to a first embodiment of the present invention.

First, the process of opening the door will be described, and for convenience, only the process of opening the right door 35R will be described.

As shown in FIG. 8, in the state in which the doors 35L and 35R are closed, the spacer 60 is engaged, and the door 35R is the elastic force of the elastic member 74 provided in the hinge mechanism 70 and 80. Since the magnetic body 55 of the gasket assembly 50 is moved toward the mating door 35L by the magnetic force, the gaskets 53 of both the doors 35L and 35R are in close contact with each other.

When the user opens the door 35R in such a state, as shown in FIG. 10, the roller 67 of the cam contact lever 65 opens the cam surface 62a of the cam member 61 as the door 35R opens. In addition to translating the door hinge shaft 72b of the right door 35R in the right direction while moving on the other hand, the hinge link 72 is rotated counterclockwise.

And when the roller 67 reaches the apex 62b of the cam surface 62a of the cam member 61, the door 35R is positioned at the maximum movement displacement during translational movement.

At this time, the hinge link 72 of the hinge mechanism 70, 80 rotates the door hinge shaft 72b, which is the center of rotation of the door 35R, by the mutual interference of the spacer 60 in the counterclockwise direction.

In particular, by the counterclockwise rotation of the hinge link 72, the door locking member 94 of the detent mechanism 90 passes over the bend 93 of the main body locking member 94 by a predetermined angle in the counterclockwise direction. Is rotated.

This will be described in more detail with reference to FIGS. 8 to 10 as follows.

First, as shown in FIG. 8, in the state in which the door 35 is closed, the bending of the door locking member 92 and the main body locking member 94 corresponds to the bar / body locking member 92 ( 94 are locked to each other to prevent the rotational center of the door 35R from moving.

As shown in FIG. 9, when the roller 67 of the cam contact lever 65 is located at the vertex 62b of the cam member 61, the main body locking member 94 is predetermined in the counterclockwise direction. It is rotated at an angle, and the bending peak 94a of the main body locking member 94 is positioned on an inclined surface passing through the bending peak 92a of the door locking member 92.

10, when the roller 67 of the cam contact lever 65 is separated from the apex of the apex 62b of the cam member 61, the main body locking member of the hinge link 72 ( 94 is further moved a predetermined distance to the left on the curved inclined surface of the door locking member 92.

Thereafter, the hinge link 72 stops without being rotated about the main body hinge shaft 72a even if the door 35R is further opened, and the door 35R is centered on the door hinge shaft 72b which is the rotation center. Is rotated.

Here, the elastic member 96 is compressed by the pressure applied to the main body locking member 94 in the process of the door locking member 92 is bent over the bending of the main body locking member 94, the elastic member ( By the compression of 96, the door locking member 92 is smoothly moved upward.

Thus, when the door / body locking member 92 or 94 is stopped, the elastic member 96 applies an elastic force to the door locking member 92 to release the locking of the detent mechanism 90. When the door locking member 92 is rotated, it is compressed to smoothly move the door locking member 92.

Next, the door is closed will be described with reference to FIG.

First, when the open door 35R is closed, the door hinge shaft 72b is located in a state moved to the right as compared with the closed door 35R, the door 35R is moved to the right door hinge shaft 72b. The roller 67 of the cam contact lever 65 is not in contact with the opening cam surface 62a of the cam member 61, nor is it in contact with the vertex 62b.

That is, the roller 67 of the cam contact lever 65 does not move in the reverse direction of the opening cam surface 62a as in the prior art, but is a separate closing cam surface 62c formed on the side of the opening cam surface 62a. To return to the initial position.

In this case, the closing cam surface 62c is formed to be gentler than the inclination angle of the opening cam surface 62a, and the length thereof is also long, thereby minimizing noise generated when the roller 67 contacts the cam member 61.

In particular, the portion where the closing cam surface 62c and the roller 67 are first contacted is formed so that the roller 67 enters in a tangential direction so that noise generated when the roller 67 and the closing cam surface 62c are in contact with each other. Minimize

The closing cam surface 62c may be formed longer than the opening cam surface 62a. When the door 35R is opened, the opening cam surface 62a is formed so that the gasket assembly 50 is spaced apart as soon as possible. However, when the door 35R is closed, it is advantageous to form the closing cam surface 62c so that the gasket assembly 50 is in close contact with the mating side gasket assembly in the lateral direction as much as possible in terms of minimizing friction.

On the other hand, the roller 67 of the cam contact lever 65 is rotated about the door hinge shaft 72b to contact the closing cam surface 62c, the roller 67 is the closing cam surface 62c. When the vehicle is moved to the initial position, the door 35R is also moved to its original position with the roller 67, and the rotation center of the door 35R is also moved to the original position.

At this time, when the door hinge shaft 72b, which is the center of rotation of the door 35R, is moved to its original position, the hinge link 72 is rotated in the clockwise direction opposite to that of the door 35R.

Particularly, when the hinge link 72 is rotated in the clockwise direction, the door locking member 92 installed in the hinge link 72 locking portion 73 may bend the bending peak 94a of the main body locking member 94. Ride and move to the initial position.

In addition, when the bending peak 92a of the door locking member 92 crosses the bending peak 94a of the body locking member 94, the door locking member 92 is an inclined surface of the body locking member 94. Is moved to the initial position.

In addition, since the elastic member 74 installed on the hinge link 72 presses the door hinge shaft 72b of the hinge link 72 toward the mating door 35L, the user has a small force on the door 35R. Even if only the addition of the detent mechanism 90 can be released.

Thereafter, the gasket assembly 50 of the door 35R is in close contact with the gasket assembly 50 of the mating door 35L in the process of returning the door locking member 92 to the initial position.

Here, two valleys 104a and 104b are formed on an upper surface of the main body locking member 104, and one peak 105 is formed between the valleys 104a and 104b, and the door locking member 102 is formed. ) Is formed with a protrusion 101 seated on the valleys 104a and 104b, and the protrusion 101 serves as a peak 102a that is engaged with the valleys 104a and 104b.

Thus, when the door locking member 102 formed on the lower side of the hinge link 72 is rotated, the main body locking member 104 is moved downward while compressing the elastic member 106, the main body locking member 104 By the movement of the door locking member 102 is smoothly moved. Thereafter, when the rotation of the door locking member 102 stops, the main body locking member 104 is raised to the initial position by the elastic member 106.

At this time, when the door 35R is opened, the peak 102a of the protrusion 101 is moved from the valley 104a on the right side to the valley 104b on the left side, and when the door 35R is closed, The peak 102a of the protrusion 101 is moved from the valley 104b on the left side to the valley 104a on the right side.
