As shown in the drawing, the hinge means 234 may include a hinge shaft 234 'which is a rotation center of the support link 230, a hinge support 234 "supporting the hinge shaft 234', and the like. As shown, the hinge support 234 ″ protrudes rearward from the rear surface of the front panel 160, and is formed in pairs to support the left and right sides of the hinge shaft 234 ′.

As shown in the figure, the hinge shaft 234 ′ is installed to penetrate through the pair of hinge supports 234 ″, and may be formed of one or more components. In other words, the hinge shaft 234 ′. Although not shown in detail, 234 'may be configured such that each of the two left and right axes combine with each other to form one hinge shaft 234', wherein the two shafts are one screw. It may be configured to be fastened by.

In addition, in order to facilitate the rotation of the hinge shaft 234 ', a screwdriver may be formed on the side of the hinge shaft 234' to form a '-' or '+' shaped driver groove. As such, the reason why the driver groove is formed on the side of the hinge shaft 234 'is to facilitate the rotation of the small hinge shaft 234'. That is, when the user wants to rotate the hinge shaft 234 ', the end of the screwdriver (screw driver) is in close contact with the driver groove and then rotates, so that the hinge shaft 234' can be easily rotated. .

A hinge protrusion 234'a is formed on the outer circumferential surface of the right end of the hinge shaft 234 'in the circumferential direction. The hinge protrusion 234'a is engaged with the fixing rib 235 to be described below to prevent rotation of the hinge shaft 234 '.

Fixing ribs 235 are further formed on the rear surface of the front panel 160. As shown in the drawing, the fixing rib 235 is formed to protrude rearward from the rear surface of the front panel 160, and the fixing jaw 235 ′ is formed to protrude from an end (rear end) to extend laterally. do.

The fixing jaw 235 'serves to prevent the hinge protrusion 234'a from being separated. That is, as shown, when the hinge protrusion 234'a is inserted between the fixing jaw 235 'and the rear surface of the front panel 160, the hinge protrusion 234'a unless an external force is applied. ) Does not escape the fixing jaw (235 ').

9 and 10 show detailed configurations of the discharge panel 170 and the link 196, respectively. That is, a front perspective view of the discharge panel 170 is partially shown in FIG. 9, and a rear perspective view of the discharge panel 170 and an exploded perspective view of the link 196 are respectively shown in FIG. 10.

As shown in these figures, the panel support 240 is formed at both ends of the discharge panel 170, respectively.

That is, when the discharge panel 170 moves downward, when the lower end of the connection slit 198 is inserted into the fixing groove 244, the discharge panel 170 no longer flows downward.

A plurality of panel protrusions 250 are further formed on the front surface of the discharge panel 170. That is, a plurality of panel protrusions 250 protruding a predetermined portion toward the front is formed on the front surface of the discharge panel 170. The panel protrusion 250 serves to allow the front panel 160 and the discharge panel 170 to be spaced apart from each other when the discharge panel 170 flows up and down. That is, the discharge panel 170 and the front panel 160 do not directly contact each other, and the front end portion of the panel protrusion 250 and the rear surface of the front panel 160 are in contact with each other.

The frame protrusion 252 is formed on the rear surface of the discharge panel 170. The frame protrusion 252 allows the front frame 130 and the discharge panel 170 to be spaced apart from each other when the discharge panel 170 moves up and down. That is, when the discharge panel 170 flows up and down, the rear end of the frame protrusion 252 and the front frame 130 come into contact with each other.

The reason for forming the panel protrusions 250 and the frame protrusions 252 on the front and rear surfaces of the discharge panel 170 as described above is the discharge panel 170 and the front surface when the discharge panel 170 flows. This is to reduce the contact friction force by making the contact area between the panel 160 and the front frame 130 smaller. That is, when the panel protrusion 250 and the frame protrusion 252 are in contact with each other as compared with the case in which the entire front and rear surfaces of the discharge panel 170 are in contact with the front panel 160 and the front frame 130, the discharge is performed. This is because the vertical flow of the panel 170 can be made more smoothly.

Meanwhile, one end of the panel link 196 "described above is rotatably fastened to the link fastening hook 242 of the panel support 240. Referring to FIG. 10, the panel link 196" will be described in detail. The first link shaft 196 "a rotatably inserted into the link fastening hook 242 is formed to protrude to the left side of the lower left side of the link link hook 242, and the shaft link (196) is formed on the upper right side of the panel link 196". A second link shaft 196 ″ b that is engaged with one end of 196 ′ protrudes to the right.

In addition, a hook-shaped elastic hook 196'a is formed at a lower end of the shaft link 196 ', and a fixed hook 196'b is formed at an upper end thereof. The second link shaft 196 ″ b of the panel link 196 ″ is inserted into the elastic hook 196 ′ a so as to be rotatable. The drive shaft 194 is inserted into and fixed to the fixing hook 196'b.
