Accordingly, since the lower rail 200 is rotated and completely separated from the upper rail 100 , the user can very easily wash the discharge unit 30 , and sterilization and disinfection can be performed very easily.

In this case, the lower rail 200 may be provided with a first rib 210 protruding downward. For example, the first rib 210 may protrude downward from the lower rail base 200a. For example, when the lower rail 200 is fastened to the upper rail 100 , the first rib 210 may have a shape corresponding to the circumference of the outer circumferential surface 11 .

That is, as shown in FIG. 1 , in the first operating state in which the lower rail 200 is firmly fastened to the upper rail 100 , the first rib 210 is located at the lower portion of the outer circumferential surface 11 of the juice drum 10 . However, it may be in a form corresponding to the circumference of the outer circumferential surface 11 , for example, an arc of a circle having the same radius as the outer circumferential surface 11 .

Accordingly, when it is not in the first operating state, that is, when the lower rail 200 is not securely fastened to the upper rail 100, the upper end of the main body and the lower end of the outer circumferential surface 11 do not coincide with each other, and the juice drum Since (10) is not fastened to the upper part of the main body, it is possible to prevent the leakage of residues around the juicer due to inexperience of the user, thereby preventing the juicer from being contaminated by the juicer.

As such, the user can separate the lower rail 200 from the upper rail 100 even with a small force by holding and pulling the second rib 220 protruding from the longitudinal end of the lower rail 200 . , it is not necessary to apply excessive pressure to the lower rail 200 to separate the lower rail 200 from the upper rail 100 , thereby preventing the lower rail 200 from being damaged or deformed in shape.

1 to 4 , the second rib 220 may be connected to the seating portion 231 at the upper end of the lower rail 200 . That is, the second rib 220 protrudes along the lower rail side part 200b and has a structure connected to the seating part 231 provided at the upper end of the lower rail side part 200b, so that the durability of the seating part 231 is improved. Thus, even when the first crimping part 233 compresses the upper lead of the upper rail 100 , the seating part 231 is not damaged, so that the lower rail 200 can be firmly fastened to the upper rail 100 . .

4 and 7, the juicing drum 10 includes a lower rail fastening part 12 that enables the lower rail 200 to move in the front-rear and up-down directions, and the lower rail 200 is A guide slit 250 having a predetermined length and perforated in the longitudinal direction of the lower rail 200 is provided.

The lower rail fastening part 12 includes a downward protrusion 13 protruding downward from the lower portion of the juice drum 10 and a lateral protrusion 14 protruding laterally from the lower protrusion part 13, for example, For example, the lower rail fastening portion 12 may be provided on the inner side of the outer circumferential surface 11 and the lateral protrusion 14 may be disposed at a lower position than the upper rail base 100a.

For example, the guide slit 250 may be provided on both sides of the lower rail 200 , and the lateral protrusions 14 may protrude inward from both sides of the lower rail 200 , and the guide slit 250 . Both sides of the silver are fastened to the lateral protrusion 14 , and the lateral protrusion 14 may be guided along the guide slit 250 . Accordingly, the guide slit 250 may be rotated and moved in the front-rear direction while being fastened to the lateral protrusion 14 .

Looking at the shape of the guide slit 250 in more detail with reference to FIGS. 5 and 6 , the guide slit 250 may be formed so that the width A1 of one end 251 is narrower than the width A2 of the other end, At one end 251 of the guide slit 250, a third pressing portion 251a may be provided for pressing the lateral protrusion 14 to fix the guide slit 250 in the first operating state. For example, a shape in which the width of the guide slit 250 is gradually widened from one end 251 to the other end 252 may be applied.

Accordingly, when assembled from the second operating state to the first operating state, the lateral protrusion 14 moves from the wide area of the guide slit 250 to the narrow area, so that the lower rail 200 moves upward. As the lower rail 200 is fastened to the upper rail 100 while ascending, the lower rail 200 can be assembled in the first operating state with little force.

In addition, when separated from the first operating state to the second operating state, the lateral protrusion 14 moves from the narrow area to the wide area of the guide slit 250 so that the lower rail 200 moves downward. As the lower rail 200 is separated from the upper rail 100 while going down, the frictional force acting between the elastic member 40 and the upper rail base 100a to be described later is minimized so that the elastic member 40 is separated from the lower rail 200. It is possible to prevent separation from or deformation of the elastic member 40 .

For example, one end 251 of the guide slit 250 has a shape corresponding to the shape of the lateral protrusion 14, and a shape equal to or smaller than the size of the outermost portion of the lateral protrusion 14 is applied, so that the guide slit ( A form in which the one end 251 of the 250 is the third compression part 251a may be applied. Accordingly, while applying an uncomplicated configuration, the lower rail 200 can move forward and backward through the lateral protrusion 14 and rotate in the vertical direction, and in the first operating state, the lower rail 200 moves the upper rail 100 ) to be firmly fixed to the
