または水をためた洗濯兼脱水槽の中で布を撹拌しながら
注水をつづける注水すすぎであった。Conventionally, the main rinsing method of a washing machine is rinsing for agitating the cloth in a washing and dehydrating tank in which water is stored.
Alternatively, it was a water rinsing in which water was continuously poured while stirring the cloth in a washing and dehydrating tank in which water was stored.

水量を少なくすると衣類全体が水にひたらず、節水すす
ぎができないという問題があった。However, in the case of any of the above rinses, a large amount of rinse water is required to raise the water level until the entire clothes are soaked in water. Therefore, when the amount of water is reduced, there is a problem that the entire clothing is not covered with water and water-saving rinsing cannot be performed.

Although a method of supplying water in the form of a shower has been proposed, in this case, if the water pressure of the water faucet is too low, there is a problem that the shower water does not reach the clothes and the rinsing performance deteriorates. Further, when the water pressure of the water faucet is too high, there is a problem that shower water bounces off the cloth and is scattered around.
【０００７】一方、所定のすすぎ性能を確保するために

If the shower rinsing is not repeated, the process proceeds to step 29 to perform intermediate dehydration. Then, in step 30, not only when rinsing is selected, but also when shower rinsing is selected, rinsing is performed for one or more times as a finishing step of the rinsing process. Further, in step 31, final dehydration is performed to complete the entire process.

場合と比べてかなり節約できる。The amount of water used for rinsing according to the present embodiment is shown in FIG. 4 in comparison with the amount of water used for rinsing because it is conventional. Although FIG. 4A shows a conventional case where rinsing is performed, a large amount of rinsing water is required to raise the water level until the entire laundry is immersed in water. Moreover, the amount of water used doubles when the rinse is repeated twice. FIG. 4B shows an example of the amount of water used when shower rinsing is performed according to this embodiment. Since the shower water supply amount is less than or equal to the saturated water supply amount of the laundry, it is possible to perform rinsing with a very small amount of water compared to the rinsing rinse. Further, even in the case of repeated rinsing after the second time, the water supply amount can be freely set regardless of the amount of water used for the first time. Further, even if the rinsing is performed as a finishing step of rinsing, the amount of water used in the entire rinsing can be considerably saved as compared with the case of the rinsing.

Shower water supply means for supplying water in a shower shape toward the inner wall of the water tank, and control means for controlling the operation of the motor and the shower water supply means are provided, and the control means alternately performs water supply and dewatering rotation by the shower water supply means. Since it is configured to be repeated, it is possible to obtain a predetermined rinse performance with less variation, with a much smaller amount of water than when water is rinsed by storing water in the washing / dehydrating tank.

Repeat shower rinsing,
When the value is less than the first predetermined value, the washing and dewatering tubs are rinsed by accumulating water in the tub and stirring it. Therefore, even if the water pressure of the water faucet fluctuates, the shower can only reach the cloth. Rinsing can be performed, and appropriate rinsing can be performed according to the magnitude of the water pressure of the water faucet.

When the flow rate exceeds the second predetermined value, the second water supply means is made to simultaneously perform the water supply operation. Therefore, even when the water pressure of the water faucet is high at the time of shower water supply, the water is prevented from bouncing on the cloth and scattering. It is possible to prevent water from splashing when water is supplied.

できる。Further, there is provided a rotation speed detection means for detecting the rotation speed of the washing / dewatering of the washing / dehydrating tank through a signal from the motor
The control means starts the water supply operation by the shower water supply means when the rotation speed detected by the rotation speed detection means is inertial rotation within a predetermined range, and moves to the next dehydration step after the shower water supply is completed. Therefore, it is possible to shorten the time required to shift the process of water supply and dewatering, and to apply the shower water evenly to the laundry to keep the variation in rinsing performance within a small range.
