On the other hand, as shown in Figure 3, the second latch device 530 is installed on the upper left portion of the frame 110.

Although not shown in detail, the second latch device 530 is similar to the first latch device 520, the stopper, the locking pin, the stopper groove, the locking guide groove, the housing, the locking portion, the rotation limiting portion, the insertion guide groove, and the like. It includes the configuration of the movement guide groove.

However, since the second latch device 530 is not interlocked with the latch switch device 600, the second latch device 530 is configured to be coupled to or operate with the movement guide part 526 of the first latch device 520. The difference is that there is no corresponding configuration.

In addition, the second latch device 530 is formed to be symmetrical with the first latch device 520.

As shown in FIG. 7, the first guide support part 510 is mounted to the lower left portion of the frame 110.

When viewed from the front, the first guide support part 510 is fixedly installed at the lower right side of the frame 110, and the fixing member 550 provided at the rear of the door 30 is provided to be insertable.

That is, when the door 30 rotates while the storage container 100 is coupled to the storage chamber 20, the fixing member 550 is inserted into or detached from the first guide support part 510.

The first guide support part 510 includes a housing 511, a support plate 512 provided inside the housing 511, an insertion guide groove 513 provided in the support plate 512, and the support plate 512. The stopper 514 is provided below and extends downward.

Here, the stopper 514 may be inserted into the stopper groove 131 provided at the lower right edge of the storage compartment inlet.

The stopper 514 rotates together with the door 30 in a state in which the storage container 100 is engaged with the door 30 to close the front of the storage chamber 20, and the storage container 100 is closed. It serves to limit the movement so as not to go deep into the storage compartment (20).

That is, the stopper 514 is in contact with the rear surface of the stopper groove 131 to prevent the storage container 100 from entering more than a predetermined depth toward the storage chamber 20.

The stopper groove 131 may extend in an oblique direction to correspond to the rotational trajectory of the fixing pin 552 of the fixing member 550 according to the rotational trajectory of the door, and the sidewall may be formed to have a constant curvature.

That is, since the rotational trajectory of the fixing member 550 close to the rotating part of the door 30 draws a curve, the sidewall of the door 30 has a curvature so as to correspond to the trajectory.

As shown in FIG. 3, a second second guide support part 540 is also mounted on the upper right part of the frame 110.

The second guide supporter 540 has the same configuration as that of the first guide supporter 510, but its shape is symmetrical with respect to the first guide supporter 510.

Hereinafter, an operation of the latch device will be described with reference to the accompanying drawings.

8 is a plan sectional view showing that the fixing member is coupled to the first latch device.

8 illustrates that the fixing member is inserted into and supported in the first latch device so as to realize a state in which the storage container is attached to the door.

As shown in FIG. 8, the fixing member 550 is inserted into the insertion guide groove 5211 of the housing 521.

In this state, the fixing pin 551 of the fixing member 550 is disposed in the locking groove 5252, and the sidewall of the locking groove 5524 is disposed to surround the fixing pin 551.

That is, the locking groove 5524 serves as a stopper with respect to the fixing pin 551 to prevent the fixing member 550 from being separated out.

At this time, the locking pin (5247) of the locking portion 524 is located on the right side of the movement guide groove (5244) is prevented from being caught in the locking guide groove (Figs. 4, 112). As a result, the binding between the storage container 100 and the main body 1 is released.

In order for the locking portion 524 to reliably support the fixing member 550, rotation of the locking portion 524 should be prevented in this state.

To this end, an insertion part 5252 provided in the motion guide part 526 is inserted into the first insertion groove 5244 of the locking part 524 to prevent rotation.

On the other hand, the first extension portion 5252 of the rotation limiting portion 525 is pushed by the support pin 552 of the fixing member 550 to move backward from the insertion guide groove 5211, accordingly the rotation The limiting portion 525 is rotated and positioned as a whole.

In this case, the stoppers 111 and 121 are located in the stopper groove 523, and the stopper groove 523 surrounds the rear and side surfaces of the stoppers 111 and 121.

However, in this state, when the door 30 and the storage container 100 are bound and the user pulls the door 30, the door 30 and the storage container 100 rotate forward at the same time, and the storage chamber ( 20) is open.

In particular, the locking pin (5247) is located on the right side of the locking guide grooves (112, 122), because the locking guide grooves (112, 122) are opened to the front, the door 30 and the storage container 100 Even if it moves forward along the can be moved freely without being caught by the locking guide groove (112, 122).

Thus, smooth opening of the door 30 and the storage container 100 can be realized.

As shown in Figure 9 (a), the engaging portion 524 of the first and second latch device serves to hold the fixing member 550.

The locking grooves 5252 of the locking portions 524 and 534 surround the fixing pins 552 of the fixing member 550 to prevent the fixing member 550 from falling out.

As a result, the door 30 and the storage container 100 may be bound.

The exercise guide part 526 is moved by the pressing operation of the pressing part 522. Since the pressing part 522 is provided only in the first latch device, the exercise guide part 526 is also used only in the first latch device. It needs to be prepared.

The insertion part 5252 of the exercise guide part 526 is inserted into the first insertion groove 5244 to prevent rotation of the locking part 524. In addition, the contact piece 5203 provided in the exercise guide part 526 may be rotated at any time when the pressing part 522 moves forward by maintaining the contact state with the pressing part 522. This may cause the locking portion 524 to rotate.

As shown in FIG. 9B, the fixing member 550 is also inserted into the first guide support part 510.

The insertion guide groove 513 provided in the first guide support part 510 guides the movement of the fixing pin 552 of the fixing member 550 in a diagonal shape.

When the fixing pin 552 is located at the rear of the insertion guide groove 513, the front of the fixing pin 552 is covered with the locking jaw 516 extending from the housing 551 and the fixing pin ( 552 is prevented from falling out in the front direction rather than the oblique direction.

10 (a) illustrates an intermediate process in which the fixing member 550 is separated from the first latch device 520, and FIG. 17 (b) shows the fixing member (1) in the first latch device 520. 550 is shown in a completely separated state.

As will be described later, when the button 610 provided in the handle 32 disclosed in FIG. 12 is pressed, an internal link structure is operated, and the latch switch device 600 protrudes from the inner surface side of the door 30. The release pin 650 is further protruded toward the first latch device 520.

As a result, as shown in FIGS. 10A and 10B, the pressing part 522 is pressed by the release pin 650 to move into the housing 521, and thus the movement guide. The extension part 5203 of the part 526 is pressed.

When the contact piece 5203 is pressed, the motion guide part 526 is rotated, the rotation direction of the motion guide part 526 is clockwise in this figure.

As a result, the insertion part 5203 is separated from the first insertion groove 5244 of the locking part 524.

Since the locking part 524 is connected to the exercise guide part 526 and the second elastic member 5292, when the exercise guide part 526 moves clockwise, the exercise guide part 526 is moved. Pulled by the locking portion 524 is rotated counterclockwise.

Accordingly, the locking groove (5242) is rotated forward from the side, thereby releasing the locking state with the locking pin 552 to create an environment in which the locking pin 552 can move forward.

On the other hand, when the locking portion 524 is rotated counterclockwise, the locking pin (5247) is moved to the left of the movement guide groove (5244). In this way, the locking guide grooves (see FIGS. 4 and 112) move to the right side and are surrounded by the locking step 112a of the extension groove of the locking guide groove 112.

On the other hand, the first extension portion 5252 of the rotation limiting portion 525 is in contact with the fixing pin 552 of the fixing member 550, the rotation limiting portion 525 is the first elastic It is connected to the member 5291.

The first elastic member 5291 is connected to the second extension portion 5292, and provides an elastic restoring force to pull the second extension portion 5292, so that the rotation limiting portion 525 is a clock. It is intended to rotate in the opposite direction.

Therefore, when the locking member 550 is released from the locking portion 524, the rotation limiting portion 525 rotates counterclockwise, and the first extension portion 5252 is the locking pin. Push 552 forward.

In this state, when the user pulls the door (see FIG. 1, 30) forward, the fixing member 550 is moved forward from the insertion guide groove (5211).

When the fixing member 550 is completely removed from the latch device 520, the rotation limiting part 525 further rotates in the counterclockwise direction, and an insertion part provided in the rotation limiting part 525 ( 5255 is inserted into the second insertion groove 5245 provided in the locking portion 524.

Thereby, the locking part 524 can be prevented from further rotating.

As a result, the door 30 and the storage container 100 are separated so that the bobbin storage room 100 is located in the main body, and when the user pulls the door 30 open, the front surface of the storage container 100 is opened. The user can be exposed or withdrawn the article.

The second latch device 530 is the movement guide portion 526 is omitted in comparison with the first latch device 520, the engagement and separation between the locking portion and the fixing member is the second latch device 530. Since the same as the separation operation of the second latch device 530 and the fixing member 550 will be replaced with the description of the separation operation between the first latch device 520 and the fixing member 550 described above.

On the other hand, the stopper 111 is located in the stopper groove 523, the stopper groove 523 surrounds the rear and side of the stopper 111.

In this state, when the door 30 and the storage container 100 are separated and the user pulls the door 30, only the door 30 rotates forward, and the storage container 100 is opened.

The locking pin 5247 is located in an extension groove provided on the left side of the locking guide groove 112. Since the extension groove is blocked by the locking step 112a, the door 30 is closed. Even when opened forward, the locking pins 5247 are limited to the locking step 112a to move forward.

Therefore, smooth opening of the door 30 can be realized.

As shown in FIG. 11A, the locking part 524 of the first latch device is separated from the fixing member 550.

The catching groove 5524 of the catching portion 524 faces the front, so that the state surrounding the fixing pin 552 of the fixing member 550 is released, whereby the fixing member 550 can be pulled forward. have.

As a result, the door 30 and the storage container 100 may be separated.

The exercise guide part 526 is moved by the pressing operation of the pressing part 522. Since the pressing part 522 is provided only in the first latch device 520, the exercise guide part 526 is also the first. It only needs to be provided for the latch device.

The insertion part 5252 of the exercise guide part 526 is separated from the first insertion groove 5244 to guide the rotation of the locking part 524.

In addition, the contact piece 5263 provided in the exercise guide part 526 maintains a state in contact with the pressing part 522, and the pressing part 522 moves forward to rotate. It may cause the locking portion 524 to rotate.

As shown in FIG. 19B, the fixing member 550 is separated from the first guide support part 510.

The insertion guide groove 513 provided in the first guide support part 510 guides the movement of the fixing pin 552 of the fixing member 550 in a diagonal shape.

Since the fixing member 550 adjacent to the first guide support part 510 rotates while drawing a curve, the fixing member 550 may move forward with the insertion guide groove 513 formed in the diagonal direction, thereby moving forward. The one guide support 510 may be separated from the fixing member 540.

In the above, the process of separating in the state in which the storage container 100 and the door 30 are coupled, but the process of recombining in the separated state is performed in the reverse order of the above-described process.

As described above, the coupling and separation process between the first latch device 520 and the fixing member 550 is substantially similar to the coupling separation process between the second latch device 530 and the fixing member 550. The description of the first latch device 520 will be replaced with the description of the second latch device 530.

In other words. 10 (b), the user pushes the door 30 while the fixing member 550 and the first latch device 530 are separated to lift the fixing member 550 as shown in FIG. 10 (b). Enter the latch device 520.

The fixing member 550 is inserted into the insertion guide groove 5211 and pushes the first extension part 5252 of the rotational limiting part 525 back.

As a result, the rotation limiting part 525 rotates in a clockwise direction, whereby the insertion part 5255 of the rotation limiting part 525 is separated from the second insertion groove 5245 of the locking part 524. .

As a result, the locking portion 524 may rotate in a clockwise direction.

The fixing pin 552 of the fixing member 550 enters the locking groove 5252, and pushes the locking groove 5524 back to rotate the locking portion 524 in a clockwise direction.

When the locking portion 524 rotates clockwise, the movement guide portion 526 connected by the locking portion 524 and the second elastic member 5292 is pulled out.

As a result, the motion guide part 526 rotates counterclockwise.

Accordingly, the first insertion groove 5244 and the insertion portion 5262 of the exercise guide part 526 are close to each other.

When the fixing member 550 completely enters, the locking groove 5252 of the locking portion 524 faces the side, and the fixing pin 552 is surrounded by the locking groove 5252. This will be.

In addition, the insertion part 5252 of the exercise guide part 526 is inserted into the first insertion groove 5244 to limit the rotation of the locking part 526.

As a result, the fixing member 550 may be completely restrained by the locking portion 524 to prevent the fixing member 550 from being separated in the forward direction.

Thus, the link member 630 maintains the initial rotational position by the spring 626 under the push lever 620 and the spring 660 between the inner surface of the third case 683 and the slider 640. Doing.

Next, when the door 30 of the refrigerator is closed to the main body 10, as shown in FIG. 16, the front surface of the main body 10 pushes the push bar 710.

Then, the stopper is rotated as shown, so that the locking projection 627 of the push lever 620 may move downward without being caught by the bent portion 726.

When the user presses the button 610 in this state, as shown in FIG. 16, the push lever 620 moves downward to rotate one end of the link member 630 by a predetermined angle.

Thus, when the other end of the link member 630 pushes the slider 640 a predetermined distance, the spring 660 is compressed with respect to the inner surface of the third case 683 and coupled with the slider 640. The release pin 650 pushes the pressing part 522 of the first latch device 520 while further protruding from the inner surface of the door 32.

When the pressing unit 522 is pressed, the locking state of the first latch device 520 is released as described above, so that the fixing pin 552 of the fixing member 550 is the first latch device 520. You can get out of it.

As a result, when the user opens the door 30 by releasing the lock state of the first latch device 520 by pressing the button 610 in the state in which the door 30 is closed, the first latch device 520. Since the fixing member 550 is removed from the door, only the door 30 is opened while the storage container 100 is separated from the door 30 while being coupled to the refrigerating chamber 20.

On the other hand, when the force for pressing the button 610 is removed, the spring 626 under the button pushes the push lever 620 and the button 610 upwards to return.

According to the present invention, in operating the latch switch device for releasing the locking state of the latch device, a stopper device is provided to ensure that the door is operated only in a closed state, whereby the door is opened with the storage container coupled to the door. When the user carelessly operates the latch switch device, it is possible to reliably prevent the storage container from falling out of the door.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Changes will be possible.
