Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a two-tub washing machine for general household use.

Conventional configuration and its problems Conventionally, in this type of two-tub washing machine, clothes are washed in the washing tub, centrifugally dehydrated in the dehydrating tub, then rinsed in the washing tub, and then centrifugally dehydrated in the dehydrating tub. The washing process is finished. At this time, the detergent solution was drained by spin-drying after washing, and the rinse liquid was drained by spin-drying after rinsing.

Purpose of the Invention The present invention is a method of centrifugal dehydration of detergent solution and rinsing solution. Instead of draining the dehydration solution, the dehydration solution is recovered and reused as a washing solution or rinsing solution. be.

Structure of the Invention The two-tub washing machine of the present invention has a thicker diameter at the upper part of the dehydration tank, allows the dehydration liquid to be moved above the dehydration tank by centrifugal force, and allows the centrifugal dehydration from the top to the outside. The dehydrating liquid is collected into the washing tub from a receiving part provided around the upper part of the dehydrating tub through an inlet.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to accompanying drawings. In Figure 1, 1 is the main body with a washing tub 2 inside.
It has a washing blade 6 at the bottom which is driven by a motor 3 and a belt 4. Reference numeral 6 denotes a dehydration tank, which has a larger diameter at the top, and uses centrifugal force to move the dehydration liquid to the upper part of the dehydration tank, and centrifugally dehydrates it outward through the dehydration hole 7 at the top. A dehydration receiver 8 is provided around the dehydration tank 6, and a receiving portion 9 for receiving the dehydration liquid is provided above. The receiving part 9 has a stepped part 10 and a partition 11
It is more formed. A dehydration receiver cover 12 is provided on the top of the dehydration tank 6. The dehydration tank 6f4 is rotationally driven by the motor 13, and the dehydration tank 1III 114 is sealed with water by the oil seal 15. At the bottom of the dewatering tray 8 are drains 1', I.
A dewatering hose 17 is provided to drain water from the main body 1.

Fig. 2 is a view of the cell with the dehydration receiver cover 12 removed.6, the receiving part 901 provided above the dehydrating receiver 8, and the receiving part 9 connected to the rear injection 1-Jl8. The received dehydrated liquid flows through the two-stage section 10 and enters the washing tub 2 from the inlet 18.
\It will be collected.

Figure 3 (d) is a vertical cross-sectional view of the dehydration tank 6 as seen from the right side of the main body 1; It is inclined 1 toward the entrance 18.

-4 To explain the operation in the second configuration, clothes and detergent liquid or rinsing liquid are placed in the washing tub 2, and the motor 3 is used to wash the washing tub.
Wash and rinse by rotating and shaking 6. After washing or rinsing, clothes are placed in the spin-drying tank 6, and as the motor 13 rotates the clothes, centrifugal force causes the spin-drying liquid to move upwards in the larger diameter area, and through the spin-drying hole 7, the centrifugal force causes the clothes to be drawn into the dehydration tank 9. The water is collected from the stepped portion 10 into the washing tub 2 through the inlet 18.

In this way, the dehydration is collected in the washing ff4 tank 2,
At the beginning of dehydration, dehydration occurs rapidly and a large amount of liquid enters the receiving part 9, but the amount of dehydrated liquid gradually decreases until finally no dehydrated liquid comes out, and the dehydration ends.

Therefore, the liquid that is rapidly dehydrated in the initial stage and enters the receiving part 9 flows toward the inlet 18, but passes over the partition 11 and enters the dewatering receiving part 8 to be drained. Preventing this 1. -i: For smooth recovery, the receiver forms a small pinched portion C with a narrower width shifted between the front 9A and rear 9B of the portion 9. Therefore, when flowing through the narrow narrow part C, the flow rate decreases and the speed decreases, so the flow does not suddenly flow from A to B.
Therefore, the dewatering liquid does not overflow beyond the partition 11 at the rear 9B 6, and therefore the dewatering liquid is effectively collected from the dewatering receiver 8 without being drained.

Effects of the Invention As is clear from the general light, the present invention has the following effects:
Increase the diameter of the upper part of the dehydration tank to move the dehydrated liquid to the upper part of the dehydration tank by centrifugal force. A receiving part is provided to receive the dehydrating liquid 6, and the receiving part collects the dehydrating liquid from the receiving part to the washing tub.Injection 1
1 is provided, and the width of the receiving section is narrowed on the way to the injection section 1, so that the dehydrating solution does not overflow at the receiving section and the dehydrating solution can be efficiently collected into the washing tank. Wear,.
