Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a dewatering and rinsing device for pouring water into a dehydrating basket in a two-tub washing machine and dewatering by rotating the basket.

(Prior art) This type of dehydrating and rinsing device is designed to squeeze out the detergent contained in the laundry by soaking the laundry in fresh water and then spinning a dehydrating basket at high speed to dehydrate the laundry. The performance is greatly influenced by the amount of water that can be contained in the laundry, and the higher the amount of water, the better the rinsing performance.

In view of these points, the present applicant has already proposed a dewatering and rinsing device shown in FIGS. 3 and 4. In the figure, 1 is an exterior body, 2 is a dehydration receiving tank, 3 is a dehydration basket with many small holes, 4 is a water receptacle fixed to the basket 3 so as to cover the outer circumference of the lower part of the dehydration basket 3, and 5 is a dehydration basket. A motor for driving the basket 3; 6 an inner lid having many small holes; 7 a dehydration lid covering the upper part of the inner lid 6;
8 is a water supply passage connected to a water faucet 10 via a water supply valve 9 and injects water into the dehydration basket 3 through a small hole in the inner lid 6; This is an auxiliary water supply passage for injecting water, and when the water supply valve 9 is opened, water supplied from the water supply passage 8 flows into the dehydration basket 3 through the small hole in the inner lid 6, and is supplied into the water receiver 4 from the auxiliary water supply passage 11. The removed water flows into the lower part of the dehydration basket 3 through its small holes. That is, water is poured into the dehydration basket 3 from above and below at the same time, so that the laundry is evenly soaked with water from above and below, thereby increasing the water content of the laundry. After pouring water for a predetermined period of time, the motor 5 is driven to rotate the dewatering basket 3 at high speed, and the water contained in the laundry is squeezed out along with the detergent.By repeating such water pouring and dewatering operations, Perform a dehydration rinse. In addition, 4a in the figure is the water receptacle 4.
The reinforcing ribs are shown.

(Problems to be Solved by the Invention) Although the above structure can improve the rinsing performance by impregnating laundry with a large amount of water, it still cannot be called satisfactory due to the following points. That is, since the dewatering basket 3 was stopped when water was poured, the amount of moisture contained in the laundry was uneven between positions near and far from the water supply port 11a of the auxiliary water supply passage 11, The laundry that is washed does not easily contain moisture, and there is a possibility that the detergent cannot be removed efficiently.

However, in the present invention, the laundry can be uniformly hydrated without being affected by the position of the water supply port of the auxiliary water supply passage.

(Means for Solving the Problems) The content of the present invention will be explained below with reference to FIGS. 1 and 2, and also FIGS. 3 and 4, which correspond to embodiments.

a dehydration basket 3 having a large number of small holes; a water supply passage 8 for injecting water into the dehydration basket 3 through its upper opening;
Auxiliary water supply passage 1 branched from the water supply passage 8
1, and a water receiver 4 that receives water from the auxiliary water supply passage 11 provided on the outer periphery of the lower part of the dehydration basket 3 and allows the water to flow into the dehydration basket 3 through a small hole. In a dehydration rinsing device that performs dehydration rinsing by rotating the dehydration basket 3 at high speed, the dehydration basket 3
The drive motor 5 is turned on in short cycles when water is poured,
This is to turn it off. Note that the ON time of the motor 5 is set within a range that does not cause water to scatter due to centrifugal force.

(Function) With the above configuration, since the dewatering basket 3 rotates intermittently when water is poured, the water supplied from the auxiliary water supply passage 11 can be uniformly contained in the laundry at the bottom of the dehydrating basket 3. .

(Embodiment) The embodiment of the present invention shown in FIGS. 1 and 2 will be described below with reference to FIGS. 3 and 4.

12 is the commercial AC power supply, 13 is the motor 5 turned on,
Triax to control OFF, 14, water supply valve 9
15 is an electronic control unit that controls the triaxes 13 and 14;
When the dehydration rinse start switch 16 is turned on, this electronic control section 15 operates the motor 5 via the triaxes 13 and 14 as shown in the time chart in FIG.
and ON/OFF control of the water supply valve 9.

In the above configuration, when the dewatering rinse start switch 16 is turned ON, the electronic control unit 15 turns on the triax 14 to open the water supply valve 9, and controls the triax 13 at a cycle of, for example, 1 second OFF and 0.5 seconds ON, to turn on the motor 5. The water injection operation is started by intermittently driving the . During this water injection operation, the dewatering basket 3
The water is injected from above and below through the water supply passage 8 and the auxiliary water supply passage 11 to efficiently soak the laundry with water. Moreover, the intermittent rotation of the dehydration basket 3 ensures that the laundry at the bottom is evenly and uniformly soaked with water. can be included.

Then, when a predetermined period of time has elapsed, the electronic control unit 1
5 closes the water supply valve 9 and continuously drives the motor 5 to perform the dewatering operation. This dehydration operation squeezes out the detergent along with the water contained in the laundry.

Thereafter, dehydration and rinsing is performed by repeating such water injection and dehydration operations an appropriate number of times. Not only can the water content be increased, but also the laundry at the bottom can be soaked with water evenly and uniformly, and the rinsing performance can be significantly improved.
