A lower surface (refer to FIG. 8 ) of the guide tube vertical portion 872c may be inclined downward toward the tube connection portion 875 from one side connected to the guide tube horizontal portion 872d. That is, as the lower end of the guide tube horizontal portion 872d extends in a direction closer to the tube connection portion 875, the distance between the upper end of the guide tube vertical portion 872c and the upper end in the vertical direction may be gradually increased. .

As such, the lower surface of the guide tube horizontal portion 872d may have a downward inclination as it extends from the guide tube vertical portion 872c in the direction of the tube connection portion 875 . With this structure, it is possible to improve the bending of the drain tube 88 and prevent an air pocket from occurring. In addition, even if an air pocket is generated, the drained water can flow smoothly by not staying in the drain tube 88 for a long time.

That is, the inclined portion 878 may primarily guide the drain tube 88 toward the drain valve 881 so that the drain tube 88 is gently bent.

In addition, when air is mixed as water flows from the guide tube horizontal portion 872d to the tube connection portion 875, water cannot escape as much as the volume of air to prevent flow resistance from occurring, so that water flows into the guide tube It is possible to prevent a reverse flow to the horizontal portion 872d or a water overflow phenomenon from occurring.

In addition, an inclined portion 878 may be formed at the front end of the guide tube horizontal portion 872d connected to the tube connection portion 875 . The inclined portion 878 may be formed to have a smaller cross-sectional area from the front end of the guide tube horizontal portion 872d toward the tube connection portion 875 .

In addition, the tube connection part 875 may be connected to the inclined part 878 downwardly with reference to FIG. 8 . That is, the tube connection part 875 is formed to be inclined downward as it extends in the direction of the drain tube 88 .

With this structure, due to the inclination formed in the tube connection part 875 , the drain tube 88 can be gently extended in the direction of the drain valve 881 without sharp bending. In detail, as shown in FIG. 6 , the drain tube 88 may be connected to have a natural downward inclination while being connected to the tube connection part 875 . As shown in part A of FIG. 6 , the drain tube 88 extends toward the drain valve 881 and is not bent, but passes between the tube connection part 875 and the drain valve 881 . can be connected

Accordingly, as the drain tube 88 extends toward the drain valve 881, it is possible to prevent air pockets from being generated due to bending. When the drain tube 88 has a bent portion and an air pocket is generated, the water flowing through the drain tube 88 may be reversed by the air pocket or the flow may be stopped.

In addition, by preventing air from being mixed into the guide tube horizontal portion 872d and the inclined portion 878, smooth drainage is possible.

In addition, with reference to FIG. 8 , the upper end of the tube connection part 875 may be located lower than the water level h1 of the horizontal part 872d of the guide tube. Accordingly, it is possible to prevent air from mixing between the guide tube horizontal portion 872d and the tube connection portion 875 . Accordingly, water flowing from the horizontal portion 872d of the guide tube in the direction of the inclined portion 878 may be introduced into the tube connection portion 875 without mixing of air.

In addition, a guide rib 793 coupled to the cylinder 794a and connected to the piston to guide the movement of the rod 794b protruding to the outside of the cylinder 794a may be included.

A rod 794b protruding outside the cylinder 794a is connected to the piston. The rod 794b has one end connected to the piston and the other end coupled with the auto closing device 794c so that the restoring force of the spring can be transmitted to the water tank 70, so that the water tank 70 and selectively mutually may be arrested

An auto closing device 794c may be coupled to the front end of the rod 794b. For example, a groove of a predetermined size may be formed in the front end of the rod 794b, and the auto closing device 794c may be selectively seated in the groove.

The auto closing device 794c may be connected to an elastic member (not shown). When the water tank 70 is completely drawn out, the locking member 794d and the auto closing device 794c are separated from each other. And, when the user pushes the water tank 70 in, the moving rail moves rearward, and when it is further retracted beyond the set position, the water tank is caused by the restoring force of the elastic member of the auto-closing device 794c.
