The space formed inside the water supply body 220 may be defined by the inner bottom surface 222, the inner side wall 224, the inner front wall and the inner rear wall of the water supply body 220. In addition, a plurality of water supply passages 240 may be defined by a plurality of walls protruding from the inner bottom surface 222 . In one embodiment of the present invention, the receiving unit 230 is provided on the inner rear wall of the water supplying body 220 and may be connected to the water supplying unit 50 .

Meanwhile, the drainage unit 250 communicates with the water supply passage 240 to deliver water, and may be provided to discharge the water delivered from the water supply passage 240 to the outside of the water supply unit 200 . For example, the drainage unit 250 may include a hole penetrating the water supply body 220 so that water is discharged to the outside of the water supply unit 200 .

The drainage unit 250 may discharge water through various methods. For example, the drainage unit 250 may be connected to a hose to discharge water through the hose, or may discharge water through a hole formed in the water supply unit 200 to discharge water through a dripping method.

Meanwhile, a plurality of drainage units 250 may be provided. That is, the water supply unit 200 may be provided with a plurality of drainage units 250 partitioned. As described above, the storage unit 300 may be partitioned from each other to form a plurality of spaces in which detergents are stored, and water may be supplied to each of the plurality of spaces formed in the storage unit 300, so that the water supply unit 200 ) may be provided so that a plurality of drainage parts 250 correspond to a plurality of spaces of the storage unit 300 to discharge water.

In addition, the drainage unit 250 may be provided to supply water to the storage unit 400 or the tub 20 together with the storage unit 300 . For example, at least one of the plurality of drainage units 250 may be provided so as to avoid the storage unit 300 and provide water to the inside of the accommodation space, and at least one of the plurality of drainage units 250 may be provided in the tub 20 It may be provided to directly supply water to the tub 20 by discharging water through the tub hose 54 connected to the tub 20 .

Referring to FIG. 7 , in one embodiment of the present invention, the drainage unit 250 may include a first drainage unit 251 and a second drainage unit 252 . The first drainage unit 251 may be located relatively far from the receiving unit 230 , and the second drainage unit 252 may be located relatively close to the receiving unit 230 .

7 shows a first drainage unit 251 located at the inner front side of the water supply body 220 and a second drainage unit 252 located at the rear side of the water supply body 220 according to an embodiment of the present invention. However, the positions of the first drainage unit 251 and the second drainage unit 252 are not necessarily limited to the front and rear ends.

Meanwhile, the water supply passage 240 may include a first passage 241 and a second passage 243 . The first passage 241 may extend away from the receiver 230 and communicate with the first drain 251 . The second flow path 243 extends from the first drain part 251 to be closer to the receiving part 230 and may communicate with the second drain part 250 .

Specifically, the water supply unit 200 may be provided with a plurality of drainage units 250, and similarly, a plurality of water supply passages 240 may be provided. The plurality of drainage units 250 may receive water through the plurality of water supply passages 240 . 7 shows a plurality of drainage units 250 and a plurality of water supply passages 240 provided inside the water supply unit 200 .

On the other hand, as a plurality of drainage parts 250 are communicated on one water supply passage 240 extending from the receiver 230, water is discharged using fewer water supply passages 240 than the number of drainage parts 250. Since water can be supplied to the unit 250, the inside of the water supply unit 200 can be efficiently utilized and designed.

That is, if the water supply passages 240 extending from the receiver 230 by the same number as the plurality of drainage units 250 are formed, the internal design of the water supply unit 200 becomes complicated and the water supply to the drainage unit 250 is smooth. Therefore, in one embodiment of the present invention, the plurality of drainage units 250 communicate with any one water supply passage 240 to receive water, thereby efficiently utilizing the space inside the water supply unit 200. can

Meanwhile, when water is supplied to the plurality of drainage units 250 using any one water supply passage 240, the order of water supply between the drainage units 250 may be important. For example, the order of supplying water may be determined according to the characteristics of each drainage unit 250 .

Specifically, in one embodiment of the present invention, the first drainage unit 251 located far from the receiving unit 230 does not always discharge water even when water is supplied through the receiving unit 230, and selectively drains water as needed. It can be arranged to discharge.

For example, the first drainage unit 251 may be connected to a hose including a valve to discharge water through the hose, and in a state in which the valve is closed, even if water is supplied to the corresponding water supply passage 240, the water supply passage 240 is not supplied. Water may not be discharged to the first drainage unit 251 .

At this time, the water supply passage 240 first supplies water to the second drain part 252 close to the receiver 230 through one water supply passage 240 and then supplies water to the first drain part 251. When is simply extended away from the receiver 230, water remains stagnant between the second drain 252 and the first drain 251, and thus an inefficient flow of water may be formed.

In this case, the water supply passage 240 between the first drain unit 251 and the second drain unit 252 is continuously subjected to pressure of the water supplied through the receiver 230 while the water is stagnant, so that the water supply unit It may cause leakage or damage to (200).

In addition, the first drain unit 251 may need to be provided with water having a higher flow rate or higher hydraulic pressure than the second drain unit 252 . For example, in the storage unit 300 or the accommodation unit 400, a larger amount of water may be supplied to a target area to which water is supplied by the first drainage unit 251 than an area corresponding to the second drainage unit 252. If necessary, water is first supplied to the second drainage unit 252 close to the receiver 230 and then supplied to the first drainage unit 251 by the quantity and pressure of the first drainage unit 251. may be disadvantageous for
