Hereinafter, the operation of the storage device of the refrigerator according to the first embodiment having the above configuration will be described.

6 is a perspective view illustrating a state in which the accommodation member is retracted.

Referring to FIG. 6, in order to mount the accommodating apparatus 100, the accommodating member supporter 200 is mounted to the molding end 32 inside the refrigerating chamber 30.

Then, after the roller member 312 is positioned in the mounting groove 203 of the housing member support 200, when the housing member 300 is lowered, the roller member 312 is the housing member support 200 ) Is received into the guide rail 201.

In this state, the first storage member 310 and the second storage member 320 are arranged in parallel in the horizontal direction in a state where the accommodating member 300 is completely retracted.

The contact member 330 is spaced apart from the bent portion 425 of the second connection member 420, and the lower extension portion 326 of the second storage member 320 is accommodated in the housing. The state of contact with the front end of the member support 200 is maintained.

In this state, the user can pull out the second storage member 320 to the front. When the user grabs the second housing member 320 and pulls it forward, the entire housing member 300 moves forward by the storage member support 200.

At this time, the roller member 312 moves forward by the guide rail 201. In addition, the lower surface of the second storage member 320 and the lower surface of the fourth extension portion 422 of the second connecting member 420 and the support roller 240 make a cloud contact.

The receiving member 300 is moved forward by the user's withdrawal and the rolling motion of the roller member 312 and the support roller 240.

7 is a perspective view illustrating a state in which the housing member is drawn out.

Referring to FIG. 7, when the housing member 300 is pulled out to a maximum withdrawal distance, the support roller 240 spans the locking surface 421, and thus the housing member 300 is no longer forward. You will not be able to withdraw it.

As described above, the locking surface 421 is recessed toward the upper side when viewed from the inside, and in this figure, and preferably has a predetermined curvature so as to smoothly contact the support roller 240.

Therefore, when the support roller 240 enters the engaging surface 421 while performing a relative cloud movement with the lower surface of the fourth extension part 422 and the extension rib 423, the support roller 240 is no longer provided. ) Relative cloud movement does not proceed.

On the other hand, in a state in which the accommodating member 300 is drawn out to a maximum withdrawal distance, the first and second accommodating members 310 and 320 are kept horizontal. In this state, the connecting member 400 also maintains the original state without rotating.

In detail, in a state where the first and second receiving members 310 and 320 are horizontal, the first connection member 410 has a front end facing upwardly than the rear end. In addition, the second connection member 420 maintains a state in which the fourth extension part 422 is parallel to the bottom surface of the second storage member 320.

Therefore, the buffer member 500 also maintains a horizontal state with the receiving member 300 as shown in FIG. In addition, both ends of the shock absorbing member 500 maintain an initial state, and the rod 520 also maintains a state of maximum insertion into the cylinder 510.

On the other hand, as shown in FIG. 7, in the state where the accommodating member 300 is drawn out by the maximum withdrawal distance, the second accommodating member 320 may be moved downward by a user's manipulation.

8 is a perspective view illustrating a state in which the second storage member according to the first embodiment is lowered.

Referring to FIG. 8, when the second storing member 320 is lowered in the state where the accommodating member 300 is drawn out to the maximum drawing distance, the second storing member is rotated by the connecting member 400. 320 is moved downward.

The second receiving member 320 is positioned below the first receiving member 310, and thus the first connecting member 410 and the second connecting member 420 rotate.

In a state in which the second housing member 320 is completely moved downward, the first connection member 410 becomes horizontal, as shown in FIG. 8, and the fourth extension part 422 of the second connection member 420. ) Is arranged to be inclined.

When the second storage member 320 is lowered, the first extension part 412 and the second extension part 414 and the second connection member 420 connected to the rear end of the first connection member 410 are provided. The fourth extension part 422 connected to the rear end of the surface contact surface. (Part A)

At the same time, the contact member 330 provided on the side surface of the second storage member 320 and the bent portion 425 of the second connection member 420 come into contact with each other so that the contact member 330 is bent. It is fitted inside 425 (part B)

Finally, the lower surface of the fourth extension part 422 of the second connection member 420, the lower surface of the extension rib 423, and the locking surface 421 are respectively the support roller 240 and the support roller ( 240 is in contact with the inclined surface disposed adjacent to.

On the other hand, when the second housing member 320 is lowered, the first connection member 410 and the second connection member 420 will necessarily rotate. At this time, the first connection member is rotated forward with respect to the rear end.

Therefore, the rod 520 fixed to the front end of the first connecting member 410 is extended in accordance with the rotation of the first connecting member 410. When the rod 520 is extended, the rod 520 is extended at a low speed by the resistance of the fluid applied to the piston 530, thereby reducing the rotational speed of the first connection member 410.

Since the first connection member 410 rotates in proportion to the downward movement of the second storage member 320, when the rotational speed of the first connection member 410 is decelerated, the second storage member 320 may be rotated. The movement speed is also reduced and the shock caused by the downward movement of the second housing member 320 can be alleviated. Therefore, the second storage member 320 is able to move downward smoothly even in a state in which food is stored therein.

In the state where the second housing member 320 is moved downward, the front end of the second connection member 420 is moved downward. Therefore, the cylinder mounting portion 514 is fixed in the position of the first receiving member 310, while the rod mounting portion 522 is moved downward so that the buffer member 500 can be disposed inclined.

On the other hand, in the state in which the second storage member 320 is lowered, the height of the second storage member 320 is lowered, thereby making it easy to check inside and store food. In addition, the view of the inside of the first storage member 310 is improved by moving downward of the second storage member 320, so that the inside of the first storage member 310 may be easily checked and the food may be easily stored. Will be.

When the use of the accommodating member 300 is completed, the user moves the second accommodating member 320 upward and then pulls the accommodating member 300 backward.

When the second storage member 320 is moved upward, the first connection member 410 is rotated in the reverse direction with the rear end as the axis. The rod 520 of the buffer member 500 is compressed according to the reverse rotation of the first connection member 410. When the rod 520 moves backward, the fluid in the cylinder 510 is moved through the orifice 532 and the check valve 534, so that the movement of the rod 520 is relatively smooth.

Accordingly, when the second storage member 320 moves upward, the deceleration action by the buffer member 500 is relatively small, and thus the upward movement of the second storage member 320 is facilitated. After the upward movement, the second housing member 320 is introduced into the rear in a horizontal state with the first housing member 310 to be in a state as shown in FIG. 6 again.

The present invention may be other embodiments in addition to the above-described embodiments, and the second embodiment will be described below.

A second embodiment is characterized in that both ends of the buffer member is rotatably coupled to the second housing member and the second connection member. Therefore, the rest of the configuration except for the buffer member is the same as the first embodiment, the same configuration uses the same reference numerals, and a detailed description thereof will be omitted.

In addition, one end of the cylinder 610 is formed with a cylinder mounting portion 612 fixed by the coupling member 430, and one end of the rod 620 is a rod mounting portion fixed by the coupling member 430 ( 622 is formed.

The cylinder mounting portion 612 is rotatably fixed by the coupling member 430 on one side of the second housing member 320. The rod mounting portion 622 is rotatably fixed to the bent portion 425 of the second connection member 420 by the coupling member 430.

In the horizontal state where the first and second storage members 310 and 320 are retracted, the buffer member 600 is the first and second storage members 310 and 2 as shown in FIG. 320) to be in a horizontal state. At this time, the rod 620 is brought into the state of the cylinder 610 as far as possible.

In a state where the first and second housing members 310 and 320 are horizontal, the connection member 400 is maintained in an unrotated state. In this state, the rod 620 of the buffer member 600 is maintained in an unextended state.

In addition, when downward movement of the second housing member 320 is started in such a state, the connection member 400 is rotated. At this time, the second connection member 420 is rotated based on the rear end, the bent portion 425 is fixed to one end of the buffer member 600 to move downward with the second receiving member 320. do.

Therefore, the rod 620 is extended while the second housing member 320 moves downward. When the rod 620 is extended by the forward movement of the piston, resistance due to the movement of the fluid is generated, and the rotation speed of the second connection member 420 is reduced.

When the rotational speed of the second connection member 420 is decelerated, the descending speed of the second storage member 320 is also slowed down. Therefore, the second storage member 320 can be smoothly moved downward, and the shock during the fall can be buffered.

After the downward movement of the second housing member 320 is completed, the user may receive food. After storing the food, the user moves the second storage member 320 upwards, and then the rear side of the second storage member 320 and the first storage member 310 are pulled back in a horizontal state. The operation of 100 is completed.
