The insertion port 610 may be formed at a position corresponding to the upper end fixing part 330 and the lower end fixing part 340 when the rotation plate 600 is rotated. Therefore, when the shelf protrusion 120 is inserted into the insertion opening 610 of the rotary plate 600, the shelf protrusion 120 is rotated to the upper end fixing portion 330 or the lower end fixing portion 340 And can be fixed.

Hereinafter, the operation of the refrigerator according to the present embodiment will be described.

FIG. 6 is a view showing a state in which the shelf is vertically adjusted in height. 7 is a perspective view showing a state where the shelf is positioned above. 8 is a perspective view showing the shelf in a downward position.

6 to 8, the shelf protrusions 120 protruded from both left and right sides of the shelf 100 include insertion ports 610 formed in the respective rotation units 200 on the inner wall surface of the corresponding refrigerating chamber 30, .

When the user grasps and rotates the shelf 100 in a state where the shelf 100 is mounted, the rotation plate 600 rotates. The height of the shelf 100 can be adjusted according to the rotation of the rotation plate 600.

At this time, the shelf 100 can be pushed or pulled forward, and the rotation plate 600 can be rotated by this operation. On the other hand, when the rotary table 600 is rotated clockwise in a state where the shelf 100 is positioned at the lowermost position, or when the rotary table 600 is rotated counterclockwise The rotation is not performed due to interference between the rear wall of the refrigerating compartment 30 and the rear end of the shelf 100.

Meanwhile, when the rotary plate 600 is rotated counterclockwise while the shelf 100 is mounted, the shelf 100 is moved upward. The rotary plate 600 may be rotated until the shelf protrusion 120 is positioned at the uppermost end of the case 300.

When the shelf protrusion 120 is positioned at the upper end of the case 300, the shelf protrusion 120 is press-fitted into the accommodating portion 334 through the insertion portion 332 of the upper end fixing portion 330 . The shelf protrusions 120, which are respectively provided on the right and left sides of the shelf 100, may be fixedly inserted into the upper end fixing portion 330 in a press-fitted state. Therefore, the shelf 100 can be maintained at the uppermost position as shown in FIG.

On the other hand, when the rotary plate 600 is rotated clockwise in a state where the shelf 100 is mounted, the shelf 100 is moved downward. The rotating plate 600 may be rotated until the shelf protrusion 120 is positioned at the lowermost end of the case 300.

When the shelf protrusion 120 is positioned at the lowermost end of the case 300, the shelf protrusion 120 is press-fitted into the accommodating portion 344 through the insertion portion 342 of the bottom fixing portion 340 . The shelf protrusions 120, which are provided at the left and right sides of the shelf, may be fixedly inserted into the lower end fixing part 340 in a state of being press-fitted. Therefore, the shelf 100 can be maintained at the lowest position as shown in FIG.

The shelf 100 and the rotating unit 200 may be provided in the upper and lower portions of the inside of the refrigerating chamber 30. In this case, So that various space configurations within the refrigerating chamber 30 are possible.

Meanwhile, when the rotary plate 600 is formed of a material capable of transmitting light, the rotary plate 600 may cover the entire case 300, and the transmissive plate 500 may be omitted. In this case, the light of the light emitting member 400 can be transmitted through the rotating plate 600 and irradiated into the refrigerating chamber 30.
