FIG. 3 is a perspective view showing a top cover and an outer cover according to a first embodiment of the present invention, FIG. 4 is a plan view of the outer cover of FIG. 3, and FIG. 5 is a cross- Fig. 6 is an enlarged view of a portion A in Fig. 2. Fig.

3 and 4, the outer cover 14 is formed in a ring shape and is disposed between the outer cover 4 and the top cover 3. The outer cover (14) is fixed on the upper side of the T baby outer tank (4).

A water supply guide rib 60 is provided at a position corresponding to the water supply port 33 in the outer covering cover 14 to prevent water contained in the inner tank 6 from preventing supply of wash water.

3 and 6, the water supply guide rib 60 is disposed at a water supply guide rib 60 protruding forward by a predetermined distance d from a vertically downward position of the water supply port 33.

The predetermined distance d may include 0 and a positive integer. That is, the water supply guide rib 60 may be positioned vertically downward from the water supply port 33, or may protrude forward from the vertically downward position.

The predetermined distance d may be set in consideration of the water pressure in designing the water supply guide rib 60.

As the predetermined distance d becomes larger, the amount of washing water in the water supply becomes smaller, but the size of the opening of the outer cover 14 may be reduced, which may interfere with the pumping-out operation. It is desirable to limit the length.

The water supply guide rib 60 includes a plurality of forward and backward ribs 60a protruding forward from an inner circumferential surface of the outer tub cover 14 and spaced apart from each other by a predetermined distance, And a left-right directional rib 60b extending in the left-right direction.

The left and right ribs 60b are formed at the ends of the front and rear ribs 60a.

The portion of the left and right directional ribs 60b that is in contact with the inner circumferential surface of the outer tub cover 60 is rounded and formed to be rounded with a smaller radius than the round of the inlet and outlet holes 3a of the top cover 3 .

The left and right ribs 60b may be inclined at a predetermined angle in a direction toward the side wall of the inner tub 6.

The operation according to the first embodiment of the present invention will now be described.

When the washing machine starts operating, the washing water is supplied from the outside through the water supply device.

The water introduced through the water supply hose 13 flows into the detergent box 32 and is mixed with the detergent and is supplied into the inner tank 6 through the water supply port 33.

5 and 6, the wash water supplied through the water supply port 33 passes through the water supply guide rib 60 and can be supplied into the inner tank 6. As shown in FIG.

The user may prevent the bag from blocking the water supply port 33 when the bag is overloaded or when a bag such as a pillow is inserted and the bag is filled in the inner tank 6. [ Therefore, the water supply guide rib 60 serves to smoothly supply water through the water supply port 33.

In addition, since the wash water is supplied through the water guide ribs 60, the wash water that is supplied does not hit the pouches immediately, so that the phenomenon of scattering of the wash water caused by colliding with the pouch can be prevented.

FIG. 7 is a plan view showing an outer covering cover according to a second embodiment of the present invention, and FIG. 8 is a sectional view taken along the line A-A in FIG.

7 and 8, the outer cover 70 of the laundry processing apparatus according to the second embodiment of the present invention is provided with a water supply guide rib 72, and the water supply guide rib 72 has a plurality of forward and backward directions The structure and action of the rib 72c and the plurality of left and right directional ribs 72a and 72b are the same as those of the first embodiment, and detailed description and operation thereof will be omitted.

The plurality of left and right directional ribs 72a and 72b include first left and right direction ribs 72b formed at the ends of the front and rear direction ribs 72c and second left and right direction ribs 72b spaced apart from each other in the forward and backward directions And a plurality of second left and right directional ribs 72a arranged in a straight line.

The plurality of second left and right ribs 72a can prevent deformation such as sag as the length of the front and rear direction ribs 72c becomes longer, and can reinforce the strength.

The plurality of second left and right ribs 72a are inclined at a predetermined angle in the direction toward the side wall of the inner tub 6 so that not only the effect of dividing and spraying the water of the washing water supplied, ) Can be wetted.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
