In this case, when the auxiliary drawer 440 is first drawn out, the main drawer 460 is not drawn out first or the same as the auxiliary drawer 440. This is because a seating portion 452 is formed at both end portions of the second rolling member 462 when the second rolling member 462 tries to roll over the seating portion 452.

On the other hand, although a slight inclination is formed at the rear end of the guide rail 420 in which the first cloud member 442 rolls, the force for climbing the inclination is less than the force for crossing the seating portion 452. When the front plate 464 is pulled slowly, the auxiliary drawer 440 is first drawn out.

When the front plate 464 is gripped and slowly pulled forward, the guide catching jaw 446 formed on the auxiliary drawer 440 and the rail catching jaw 426 formed on the guide rail 420 fit each other. It will be touched, so that the withdrawal of the auxiliary drawer (440) no longer occurs.

If the guide drawer 446 and the rail catching jaw 426 continue to pull the main drawer 460 even after contacting each other, the force for the second rolling member 462 to pass over the seating portion 452 is increased. As a result, the second rolling member 462 is in contact with one side of the withdrawal rail 450 while rolling.

The main drawer 460 is drawn out from the inside of the auxiliary drawer 440 by the rolling motion of the second rolling member 462, and when the main drawer 460 is continuously drawn, the second drawer 462 is pulled out. ) Is seated on the seating portion 452 located in front of the withdrawal rail 450, the withdrawal of the main drawer 460 is no longer in progress.

When the main drawer 460 is completely withdrawn from the auxiliary drawer 440, the main drawer 460 is exposed from the inside of the drawer chamber 300 of the refrigerator to the outside and the user puts food for storage or use. Get out.                     

On the other hand, when the front drawer 464 of the main drawer 460 is pushed in to draw the double drawer 400, as in the case of pulling out the double drawer 400 by the action of the seating portion 452. The auxiliary drawer 440 is first introduced while the first cloud member 442 rolls, and after the auxiliary drawer 440 is introduced, the main drawer is sequentially inserted.

Then, after the main drawer 460 is completely drawn in, it returns to the state of FIG. 5, and seals the drawer chamber 300 by pushing the drawer door 320.

Meanwhile, in order to wash or disassemble the double drawer 400 as described above, the auxiliary drawer 440 on which the main drawer 460 is seated is slightly lifted upwards, and is pulled forward to open the front of the guide rail 420. Separate from the affected part.

Next, the main drawer 460 is pushed to the rear of the auxiliary drawer 440 to position the second rolling member 462 at the rear end of the withdrawal rail 450 and then the main drawer 460 Lifting upward, the second rolling member 462 is pulled out to be separated by the opened portion of the withdrawal rail 450.

When the double drawer 400 is to be disassembled and then mounted again, the double drawer 400 is assembled in the reverse order of disassembly.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

 In the double drawer of the refrigerator according to the present invention as described above in detail, the main drawer, the auxiliary drawer, the guide rail is formed of the same material, in particular the drawer rail for guiding the extraction of the main drawer to the auxiliary drawer is injection molding It is formed integrally.

Therefore, the number of parts can be drastically reduced, and a separate drawer can be formed only by injection molding and simple assembly without requiring a separate process, thereby greatly reducing the number of processes of the product.

In addition, by producing a double drawer using a relatively inexpensive material such as plastic it can be expected to reduce the production cost.

In addition, by using a box-type auxiliary drawer to assist the withdrawal of the main drawer, not only the rail but also the auxiliary drawer itself serves as a guide of the main drawer, so that the main drawer can be drawn out more stably. By adopting the structure to be drawn out, it is less influenced by the moment as compared to the method of drawing multiple stages on the same line of the conventional, it is possible to make the withdrawal distance longer.
