When the pinion gear 126 is engaged with the rack gear 111 and is moved, friction noise is generated. The flat portion 113 is provided at the lower end of the cover rail 110 so that the pinion gear 126 may move the rack gear 111. When the upper portion of the flat portion 113 is moved, the pinion gear 126 does not come into contact with the flat portion 113 but moves in a floating state on the top of the flat portion 113 so that no friction noise is generated.

 When the pinion gear 126 moves along the flat portion 113, frictional noise is eliminated, but since the pinion gear 126 moves without being in contact with the flat portion 113, the drawer door of the storage unit 40 ( 41) may be distorted.

The reinforcement frame 140 is connected between the sliding units 120 to prevent the drawer door 41 from being twisted. A configuration in which the reinforcement frame 140 is connected between the sliding units 120 is described below.

The lower end of the cover rail 110 is provided with a locking member 115 to be caught in the automatic door closing unit 150 to be caused to cause the automatic closing operation of the storage unit 40.

As shown in FIG. 4, the sliding unit 120 coupled to both side surfaces of the storage container 43 includes a first slide rail 121 and a first slide rail (received and fixed to the cover rail 111). A second slide rail 122 slidably coupled to 121, a third slide rail 123 slidably coupled to a second slide rail 122, and coupled to both sides of the storage container 43. A slide cover 124 to which the third slide rail 123 is fixed and a pinion gear 126 rotatably coupled to the third slide rail 123.

Although the sliding unit 120 is shown in the figure as consisting of three slide rails consisting of the first slide rail 121, the second slide rail 122, and the third slide rail 123, the second slide The rail 122 may be deleted and configured to include two slide rails including the first slide rail 121 and the third slide rail 123.

A sliding part 125 that facilitates sliding movement is provided between the first slide rail 121 and the second slide rail 122 and between the second slide rail 122 and the third slide rail 123.

The sliding portion 125 is coupled to the first slide rail 121 and the second slide rail 122, and the bearing 125a to facilitate the sliding movement of the second slide rail 122 and the third slide rail (123) Can be.

The third slide rail 123 is provided with a coupling part 123a to which the pinion gear 126 is rotatably coupled.

The pinion gear 126 coupled to the engaging portion 123 of the third slide rail 123 is flush with the rack gear 111 provided at the lower end of the cover rail 110 when the storage unit 40 is moved in the front-rear direction. By moving along the unit 113, the storage unit 40 can be slidably moved forward and backward.

Between the pinion gears 126 of the slide unit 120 respectively coupled to both sides of the storage container 43, the flow of the storage container 43 when the storage unit 40 is drawn into and taken out of the base 25, Connection bar 130 for preventing is connected.

When the pinion gear 126 moves above the rack gear 111 of the cover rail 110 while the storage unit 40 draws in and out of the base 25, the pinion gear 126 moves to the rack gear 111. And the pinion gear 126 because the rack gear 111 engaged with the pinion gear 126 is removed from the flat portion 113 when the flat portion 113 is moved past the rack gear 111 while being rotated while being engaged. ) And the flat portion 113 is not in contact with the friction noise does not occur, but the distortion of the drawer door 41 may occur.

In such a case, the reinforcement frame 140 is connected between the slide cover 124 of the slide unit 120 to prevent distortion of the drawer type door 41.

Both ends of the reinforcing frame 140 are respectively coupled to the slide cover 124 coupled to both sides of the storage container 43 to support between the slide cover 124, drawer type when the storage unit 40 is pulled in and out Warping of the door 41 can be prevented.

The automatic door closing unit 150 is mounted on the slide cover 124 of the slide unit 120 so that the storage unit 40 when the storage unit 40 reaches a certain point in the process of entering the interior of the basement 25 The storage unit 40 is moved to close the chamber 25.

As shown in FIGS. 3 and 5, the automatic door closing unit 150 includes a case 151 forming an appearance, a slider 153 linearly moving inside the case 151, and one side of the slider 153. It includes a rotator 155 rotatably coupled to the, and an elastic member 157 for connecting the slider 153 and the case 151.

The case 151 is fixed to the lower side of the slide cover 124 and accommodates the slider 153, the rotator 155 and the elastic member 157.

The case 151 is provided with a guide rail 151A for guiding the slider 153 and the rotator 155 to move along a predetermined track.

The guide rail 151A includes a straight line 151a formed in a straight line, and a locking portion 151b formed at an end of the straight line 151a so that the rotator 155 may rotate to be caught.

The case 151 is provided with a guide portion 151B in parallel with the guide rail 151A. The guide portion 151B has a locking groove of the rotator 155 to be hooked by the locking member 115 provided on the cover rail 110. It is provided to be able to engage with (155a).

The slider 153 moves on the straight line 151a of the guide rail 151A, and the position of the slider 153 is changed by the elastic force of the elastic member 157 and the user pushing or pulling the storage unit 40.

The rotator 155 is rotatably coupled to one side of the slider 153 by a coupling pin 153a. The rotator protrusion 155b does not rotate when the rotator 153 moves on the straight line 151a, but is caught by the locking portion 151b. ) Enters the engaging portion 151b and the entire rotator 155 rotates.

A locking groove 155a is provided on the upper side of the rotator 155 so that the locking member 115 may be engaged.

That is, while the storage unit 40 opens and closes the base 25, the locking member 115 is engaged with the locking groove 155a of the rotator 155 through the guide part 151B, and the slider 153 and the rotator. Reference numeral 155 moves relative to the guide rail 151A.

Next, with reference to Figures 6 to 8 will be described the operation of the storage unit 40 is drawn and withdrawn into the base 25.

First, as shown in FIGS. 6 to 7, when the storage unit 40 is retracted into the base 25, the pinion gear 126 of the slide device 100 is the flat portion 113 of the cover rail 110. ) Will be located on the top.

Since the pinion gear 126 is not in contact with the flat portion 113 when the pinion gear 126 is positioned above the flat portion 113, the pinion gear 126 may be removed during the initial operation of drawing the storage unit 40 out of the base 25. ) Is moved in a floating state above the flat portion 113 does not require a large force to pull out the storage unit (40).

When the pinion gear 126 moves above the flat portion 113 during the operation of drawing out the storage unit 40, a large force is not required, whereas the pinion gear 126 is not in contact with the storage unit 40. The drawer door 41 of the warp may occur.

Although the connecting bar 130 is connected between the pinion gear 126 to prevent the flow of the storage unit 40 during the inlet and withdrawal operation of the storage unit 40, the drawer door 41 is only connected to the connecting bar 130. Since the warpage phenomenon cannot be greatly reduced, the reinforcing frame 140 is connected between the slide units 120 to prevent the warpage phenomenon of the drawer type door 41.

As shown in FIG. 8, when the storage unit 40 is drawn out to some extent in the basement 25, the pinion gear 126 is engaged with the rack gear 111 through the plane portion 113 to rotate and move. do.

Similarly to the operation of drawing the storage unit 40 into the basement 25, when the storage unit 40 is drawn to the inside of the basement 25 to some extent, the storage unit 40 is engaged with the rack gear 111 to rotate and move. The pinion gear 126 was moved past the rack gear 111 to move the upper portion of the flat portion 113.

Since the pinion gear 126 moves the upper portion of the flat portion 113 is the same as when the storage unit 40 is drawn out, description thereof will be omitted.

In the above description of the sliding device and the refrigerator having the same with reference to the accompanying drawings, the specific shape and direction have been described mainly, which can be variously modified and changed by those skilled in the art, and such variations and modifications are within the scope of the present invention. It should be interpreted as being included.
