Is dissolved in to flow to the bottom of the detergent box (310).

The second water supply hole 222b is provided at the other side of the water supply passage 224 facing one side of the water supply passage 224. The water that does not fall through the first water supply hole 222a falls to the downstream side of the first guide member 321 through the water supply passage 224 and the second water supply hole 222b and washes past the first flow path 351. Prevents bubbles in the water.

The washing water flowing along the first flow path 351 may hit the rear surface B of the second guide member 322 according to the amount of washing water or the flowing speed thereof. In this case, a bubble may be generated to generate a detergent. And the water is not evenly mixed, and the wash water issued by the bubble does not move smoothly inside the detergent box 310, the detergent is not evenly attached to the laundry inside the rotating tub (30). As shown in FIG. 6, the water falling through the second water supply hole 222b is washed with water directed toward the rear surface B of the second guide member 322 downstream of the first flow passage 351. 322 does not hit the rear surface (B) to flow in the direction of the second flow path 352 to prevent the generation of bubbles in the wash water.

The cover frame 270 is coupled to the upper portion of the water supply frame 210. The cover frame 270 is coupled to the upper portion of the water supply frame 210 in a heat fusion manner to prevent water introduced into the water supply passage 224 provided in the water supply frame 210 from leaking to the outside of the detergent supply device 100. do.

The cover frame 270 is provided with a cover member 216 to open and close the detergent inlet 212 and the rinse inlet 214. The cover member 216 may be rotatably coupled to the cover frame 270. As described above, the user of the washing machine 1 opens only the cover member 216 that opens and closes the detergent inlet 212 and the rinse inlet 214 without having to open the door 16 that opens and closes the laundry inlet 14. Detergent or rinse can be added directly.
