  The finishing agent is input from the finishing agent input unit 15. The finishing agent input from the finishing agent input unit 15 is accommodated in the first chamber 23 of the finishing agent discharge device 22.

  When the washing process is started, the pulsator 2 rotates, and the laundry is stirred inside the washing and dewatering tub 1 by the rotation of the pulsator 2 to remove the dirt.

  After completion of the washing process, the water in the water receiving tub 3 is drained, and the laundry and dewatering tub 1 is rotated to dehydrate the laundry. Due to the rotation of the washing and dewatering tub 1, the finishing agent accommodated in the first chamber 23 of the finishing agent outflow device 22 moves to the outer peripheral side of the first chamber 23 by centrifugal force, and in FIG. 7 and FIG. As shown by an arrow a in FIG. 7, it moves to the second chamber 24 through the first movement passage 25, and as shown by b in FIGS. 7 and 8B, the outer peripheral side surface of the second chamber 24 It will be in the state pressed against.

  When the dehydration is completed and the washing / dehydration tub 1 stops rotating, the finishing agent that has moved to the outer peripheral side surface of the second chamber 24 has no centrifugal force. As shown in the figure, it moves to the third chamber 26 through the second movement passage 27.

  Next, a rinsing process is performed. A predetermined amount of water is supplied into the water receiving tank 3, the pulsator 2 rotates, and the laundry is rinsed.

  After completion of rinsing, the washing and dewatering tub 1 is rotated to dehydrate the laundry. When the washing and dewatering tub 1 rotates, the finishing agent in the third chamber 26 moves to the outer peripheral side of the third chamber 26, and as shown by an arrow d in FIGS. It moves to the fourth chamber 28 through the moving passage 29. As shown by e in FIGS. 7 and 8B, the finishing agent that has moved to the fourth chamber 28 is pressed against the outer peripheral side surface of the fourth chamber 28 by centrifugal force.

  When the dehydration is completed and the washing / dehydrating tub 1 stops rotating, the finishing agent in the fourth chamber 28 moves to the outflow passage 30 through the fourth moving passage 31 by gravity, and the water receiving tub is discharged from the outflow passage 30. 3 flows down into the space between the washing and dewatering tub 1.

  Next, a final rinse step is performed. A predetermined amount of water is supplied into the water receiving tank 3, the pulsator 2 rotates, and the final rinse of the laundry is performed. The finish is dissolved in the water of the final rinse step, and the finish is attached to the laundry.

  As shown in FIG. 2, the detergent charging cover 16 gradually protrudes toward the inside of the washing and dehydrating tub 1 as it goes to the center, in other words, it is gradually washed and removed as it goes from the center to the outer peripheral side. A tapered outer surface 16a is formed so as to approach the water tank 1 side.

  For example, in the washing process, a water flow is generated in the washing and dewatering tub 1 by the rotation of the pulsator 2, and the laundry is stirred by the water flow. The agitated laundry collides with the detergent charging cover 16, but since the detergent charging cover 16 has a tapered outer surface 16a, the laundry moves along the tapered outer surface 16a and is used for detergent loading. The cover 16 is avoided. The taper outer surface 16a can suppress the movement of the laundry due to stirring. Since the taper outer surface 16a is formed on both side surfaces of the detergent charging cover 16, it is possible to suppress the movement of the laundry from being disturbed both when the pulsator 2 is rotating forward and when it is rotating backward.

  In the opened state, the detergent charging cover 16 has a tapered inner surface 16b corresponding to the tapered outer surface 16a as shown in FIGS.

  Even when the detergent is thrown into the end of the detergent throwing cover 16, the detergent is guided to the center of the detergent throwing cover 16 by the tapered inner surface 16b. In doing so, it is not necessary to aim at the detergent and the convenience of the washing preparation work can be improved.

  As described above, the washing machine according to the present invention can improve the convenience of charging the detergent and the finishing agent without deteriorating the washing performance. It is useful as a machine.
