イルター３２で捕獲される。 In such a structure, detergent is added to the container 39 in advance for washing, and the washing tub 1 is filled with detergent.
After supplying water to the specified water level H, when the rotor blade 2 is rotated alternately left and right, the pumping action of the back blade 15 causes water to flow through the suction port 19 as shown by the arrow in FIG. 1 into the pump chamber 1.
The liquid between the washing tub 1 and the outer tub 12 that is sucked into the washing tub 8 (eventually becomes the liquid inside the washing tub).
It is sent to the water supply channel 26. As described above, the liquid sent to the first water supply channel 25 is discharged from the first discharge duct 27 toward the lint filter 32, and the liquid is discharged from the washing tub 1.
Go back inside. At this time, the thread waste contained in the liquid is captured by the lint filter 32.

できるものである。 Therefore, in the present invention, the water sealing rib 54 hanging from the lower surface of the balance ring is fitted into the groove 21 constituting the water supply channel, and extends rearward from the rear end of the discharge duct provided at the upper end of the water channel cover 22. After placing the top rib 55 that has been placed on the water sealing rib 54 and fitting the water channel cover into the groove, the top rib is strongly pressed against the water sealing rib by fixing it to the side wall of the washing tub with the screws 51. It is possible to prevent water leakage as much as possible from the contact portion between the ribs 54 and 55, which is a bent portion of the water supply channel where water leakage is likely to occur, and from the fitting portion between the water sealing rib and the washing tub.

そして送水路は凹溝と水路カバーの組合わせで
構成したので、パイプの場合と比べ材料も少なく
安価にできるものである。 Since the water supply channel is constructed by a combination of a groove and a channel cover, it requires less material and can be made at a lower cost than in the case of a pipe.
