１へ吸引される。 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 passes through the through holes 22 by the pumping action of the blades 6 of the impeller 17, as indicated by the arrow in FIG. Like pump room 2

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
It is curved downward in a recess 28 formed on the lower surface of the balance ring 27 at the mouth edge of the dehydration 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 water is first supplied to a predetermined water level, air inevitably accumulates near the top end 14 of the conical cover 12 and the annular rib 15. Therefore, the interior of the washing and dewatering tank 3 and the interior of the pump chamber 21 are not communicated here. 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 by its pumping action, is transferred to the discharge port 23, The water is sent through the water pipe 26 and into the dehydration tank 3 through the filter 29 as shown by the arrow in Figure 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 to the outside of the dehydration tank through the dehydration hole 2. 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 1 is higher than the water level H 2 between the dehydration tank and the outer tank 1.

ある。 In Figure 1, 31 is the bearing case, 32 is the motor,
These are attached to the outer bottom surface of the outer tank 1, and the outer tank 1 is suspended from the top of a machine frame (not shown).

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.

そうとする。 However, according to the dehydrating washing machine of the present invention, the liquid between the outer tub 1 and the washing/dehydrating tub 3 is sent to the filter 29 attached to the upper part of the washing/dehydrating tub by the pumping action of the impeller 7. 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. At this time, since radial auxiliary blades 35 are protruded from the back of the impeller 7, when the impeller 7 rotates, the action of the blades 35 causes the impeller 7 and the cover 1 to
The liquid between the two is pushed out in the centrifugal direction as shown by arrow Y in Figure 4.

石けん粕はフイルター２９にて確実に除去できる
という優れた効果を奏するものである。 That is, the air pocket near the top end 14 of the cover 12 acts to have a negative pressure, completely preventing liquid from directly flowing out from the pump chamber 21 to the washing/dehydrating tank 3. As a result, the liquid containing soap scum sucked into the pump chamber 21 passes over the cover 12 from the lower side to the upper side due to the action of the vanes 35 and reaches the rotor blade 5.
There is no leakage into the dehydration tank 3 from around the soap scum, and all of it is sent to the filter 29, so soap scum can be reliably captured by the filter 29 without escaping into the dehydration tank. Therefore, the laundry A in the dehydration tank is not contaminated with soap scum,
The soap scum can be reliably removed by the filter 29, which provides an excellent effect.
尚実施例の如くインペラーのポンプ作用によ
り、脱水槽内の水位H1が脱水槽と外槽間の水位
H2より高くなるようにすると、脱水槽内の水圧
が脱水槽と外槽間の水圧より高くなり、脱水孔２
を通じての脱水槽外から脱水槽内への水の流れが
完全に遮断され、脱水孔２からの石けん粕の侵入
の恐れを完全になくすることができる。 As in the example, due to the pumping action of the impeller, the water level H1 in the dehydration tank becomes the water level between the dehydration tank and the outer tank.
If it is set higher than H 2 , the water pressure inside the dehydration tank will be higher than the water pressure between the dehydration tank and the outer tank, and the water pressure in the dehydration hole 2 will increase.
The flow of water from the outside of the dehydration tank to the inside of the dehydration tank through the dehydration tank is completely blocked, and the fear of soap scum entering through the dehydration hole 2 can be completely eliminated.
