れる。 An annular rib 16 with one portion 16' open and a plurality of bosses 17 are vertically provided on the outer bottom surface of the dewatering tank 3. Reference numeral 18 denotes a dehydration tank substrate which is fixed to the drive shaft 19 of the dehydration tank 3 and serves as the bottom surface of the dehydration tank.The annular rib 16 and the boss 17 are in contact with the substrate 18, and the screw 20 is fastened to the boss 17. The substrate 18 and the dehydration tank 3 are connected together. and the cover 12
A pump chamber 21 is formed by the annular rib 16 and the substrate 18. A plurality of through holes 22 are provided in the substrate 18, and when the impeller 7 rotates, the liquid between the outer tank 1 and the dehydration tank 3 flows through the through holes 22 by the pumping action of the impeller 7.
The liquid is sucked into the pump chamber 21 as shown by the arrow in FIG.

く液体である。 At the outer bottom of the dehydration tank 3, there is a discharge port 23 of a pump chamber 21 connected to the opening 16' of the annular rib 16.
is formed. Reference numeral 24 denotes a cover attached to a corner portion of the outer bottom surface of the dehydration tank in order to form the discharge port 23. A vertical groove 25 whose lower end communicates with the upper end of the discharge port 23 is formed in the inner wall of the dewatering tank 3, and a water pipe 26 made by blow molding is fitted into the vertical groove 25. The lower end of this water pipe 26 is connected to the upper end of the discharge port 23, while the upper end is curved downward within a recess 28 formed on the lower surface of a balance ring 27 at the mouth edge of the dewatering tank 3. A filter 29 made of a mesh bag is removably installed in the dewatering tank opposite the tip of the water pipe 26. 30 is a liquid that acts as a balancer.

それに脱水孔２の数や大きさ等が設定してある。 Therefore, when the rotary blade 5 rotates during washing or rinsing, the impeller 7 also rotates, and the liquid between the outer tank 1 and the dehydration tank 3, which is sucked into the pump chamber 21 as described above, is transferred to the discharge port 23, The water is fed through the water pipe 26 and into the dehydration tank 3 through the filter 29 as shown by the arrow in Fig. 1, and then exits from the dehydration hole 2 again between the outer tank 1 and the dehydration tank 3, whereupon the same cycle is repeated. By the pumping action of the impeller, the amount of liquid sent to the dehydration tank 3 through the filter 29 is made larger than the amount of liquid flowing from the inside of the dehydration tank through the dehydration hole 2 to the outside of the dehydration tank, and the water level in the dehydration tank is increased. ( H1 )
The size and shape of the blades 6 of the impeller 7 and the number and size of the dehydration holes 2 are set so that the water level (H 2 ) between the dehydration tank and the outer tank 1 is higher than the water level (H 2 ) between the dehydration tank and the outer tank 1.

つた。 By the way, in recent years, environmental pollution caused by neutral detergents used for laundry has become a social problem, and as a result, more and more households are using powdered soap instead of neutral detergent. It adheres to the outer wall of the washing/dehydration tank and the inner wall of the outer tank.
This adhering soap scum changes color and eventually peels off, floating in the liquid between the outer tub and the washing and dehydrating tank. There was a problem that the water could enter the washing and dehydrating tank through the dehydrating hole and contaminate the laundry inside.

The soap scum floating between the outer tank 1 and the dehydration tank 3 is also sent to the filter 29 together with the liquid, where it is captured together with the lint etc. contained in the liquid.

壁１５内へ溜まるのである。 At this time, the cover 1 is
The tip 14' of the cover surrounds the tip 14 of 2.
Since the air reservoir wall 15 is lowered downward, air is always accumulated in the upper part of the air reservoir wall 15 to a point below the tip 14' of the cover as shown by the dotted line M in FIG. Completely cut off the flow of liquid to the lower side. To explain this in detail, if water is supplied into the dehydration tank 3, the water will flow into the pump chamber 21.
The water flows first between the rotor blade 5 and the cover 12, and the water level between them reaches the tip 1 of the cover 12.
4', the water flows into the pump chamber 21 and the outer tank 1, and when the water level in the pump chamber 21 reaches M, the space between the lower side of the cover 12 and the impeller 7 is sealed by water, and the water in this sealed space is Since the volume is larger than the volume above the cover tip 14' of the volume inside the air reservoir wall 15, air in the sealed space accumulates inside the air reservoir wall 15 as shown by the dotted line M in FIG. be.

優れた効果を奏するものである。 Therefore, the liquid containing soap dregs sucked into the pump chamber 21 does not leak over the tip 14' of the cover 12 into the dehydration tank 3 from around the rotary blade 5, and all of the liquid is sent to the filter 29. Therefore, all the soap scum sucked into the pump chamber can be captured by the filter 29. Therefore, the laundry A in the dehydration tank 3 is not contaminated with soap scum. Furthermore, since the pump chamber 21 and the dehydration tank 3 are sealed with air, there is no need for a complicated watertight mechanism, and excellent effects such as low cost can be achieved.

のである。 If the water level (H 1 ) in the dehydration tank is made higher than the water level (H 2 ) between the dehydration tank and the outer tank by the pumping action of the impeller as in the example, the water pressure in the dehydration tank will be equal to that of the dehydration tank. The water pressure becomes higher than the water pressure between the outer tanks,
The flow of water from the outside of the dehydration tank into the dehydration tank through the dehydration hole 2 is completely blocked, and the fear of soap scum entering from the dehydration hole 2 can be completely eliminated.
