The water between the outer tank and the dehydration tank, which is sucked into the pump chamber on the back side of the washing machine, is discharged from above the dehydration tank into the dehydration tank, and this discharge complicates the washing water flow to improve the cleaning efficiency. The tip of the discharge waterway in the pump chamber is carefully arranged to avoid taking up extra space, and the tip of the discharge waterway is used to prevent rapid movement of liquid within the balance ring. It is something.

となつていた。 In conventional dehydrating washing machines, the cross-sectional shape of the washing and dehydrating tub is close to a circular shape, and as a result, the laundry is sufficiently rotated horizontally, but not so much in the vertical direction, and there is little turnover between the top and bottom. In particular, the laundry in the upper part contains air and swells and floats on the washing water, sometimes not being washed, causing uneven washing.

ようになつている。 The water channel cover 14 has an inner diameter A of the pump chamber 7.
A pump chamber cover 24 having an opening 22 with a smaller diameter B and covering the peripheral edge 23 of the rotor blade 5 is integrally provided. The connection between the pump chamber cover 24 and the water channel cover 14 is a thin hinge 25, and the lower part of the water channel cover 14 is connected to the bottom of the dehydration tank by a screw 2.
6, and the pump chamber cover 24 is elastically engaged with the bottom of the dehydration tank by a plurality of elastic engagement pieces 27 integrally provided on the lower surface of the pump chamber cover 24. The pump chamber cover 24 can be removed from the dewatering tank 2 and rotated about the hinge 25 without tools, so that the inside of the pump chamber 7 can be easily cleaned.

て吐出せしめられる。 In the structure described above, when the rotary blade 5 rotates during washing, the water between the outer tank 1 and the dewatering tank 2 flows from the suction port 10 into the pump chamber 7 as shown by the arrow in FIG. A portion of this sucked water exits into the dehydration tank through the gap C between the opening 22 of the pump chamber cover and the rotor 5, but most of the water flows into the outer periphery of the pump chamber where the pressure is high. The water is fed into the discharge waterway 15 which is open to the inside of the dewatering tank, and is discharged from the discharge port 18 toward the center of the dehydration tank as shown by the arrow.

かんだまま洗濯されないというようなことはなく
なり、洗浄むらが解消されて洗浄率が向上する。 As a result, the washing water flow becomes a complicated turbulent flow due to the horizontal rotation by the rotary blades and the water discharged from the discharge port 18, and the laundry D is frequently changed from top to bottom. As the water falls, the laundry above does not swell up with air and remain floating on the washing water and not be washed, eliminating uneven washing and improving the washing rate.
ここで回転翼５の周縁部２３がポンプ室カバー

くしてできるだけ多くの水がスムーズに吐出水路
１５へゆくようにするためである。 The reason why the peripheral edge 23 of the rotor blade 5 is covered with the pump chamber cover 24 is to minimize the amount of water sucked into the pump chamber 7 that flows out into the dehydration tank 2.
This is to ensure that as much water as possible goes to the discharge waterway 15. The purpose of the partition rib 28 is also to reduce the eddy flow in the communication portion between the discharge waterway 15 and the pump chamber 7, so that as much water as possible can flow smoothly to the discharge waterway 15.

水を有効に洗濯に寄与させている。 Here, the amount of water discharged from the discharge port 18 is set to be larger than the amount of water discharged between the dehydration tank 2 and the outer tank 1 from the dehydration hole 29 provided on the side wall of the dehydration tank, as shown in FIG. By raising the water level in the dehydration tank and lowering the water level between the dehydration tank and the outer tank, the water between the dehydration tank and the outer tank can effectively contribute to washing.

If a removable bag-shaped lint filter is attached to the drain port and the water discharged from the discharge port is discharged into the dehydration tank through the lint filter, lint in the water can be easily removed.

果を奏するものである。 As described above, according to the present invention, the water sucked into the pump chamber during washing between the outer tank and the dehydration tank is sent to the discharge channel formed from the bottom of the dehydration tank to the upper part of the side wall, and is discharged from above the dehydration tank into the dehydration tank. Since this discharge makes the washing water flow complicated, the laundry is frequently changed from top to bottom, which eliminates uneven washing and improves the washing efficiency. The tip of the discharge waterway is located in the recess formed in the balance ring, so it does not get in the way of putting in and taking out clothes, and no extra space is required for the tip of the discharge waterway. There is no need to increase the distance between the dewatering tank and the outer tank. Furthermore, the tip of this discharge channel acts as a resistor against the movement of liquid within the balance ring, and has various excellent effects such as being useful for preventing rapid movement of liquid. .
