では、特殊操作により設定を行うようにしている。The operation display means 18 may be provided with a dedicated water supply mode changeover switch or a display. However, it is rare that such water supply setting is frequently changed due to tap water pressure. Increasing the area of the operation display unit or increasing the number of parts is wasteful, and therefore, in this embodiment, the setting is performed by a special operation.

を行うため、給水時間を短縮することができる。As described above, the present invention provides a first water supply means communicating with a water supply nozzle for supplying water into the washing and dewatering tub, and a shower nozzle for supplying water to the laundry in the washing and dewatering tub in a shower-like manner. A second water supply means communicating with the water supply means, a water level detection means for detecting a water supply water level of the washing and dewatering tub, an operation display means for setting a process and displaying operation, and sequentially controlling each process of washing, rinsing, and dehydrating. Control means for supplying water to the washing and dewatering tub by simultaneously operating the first and second water supply means, and operating the second water supply means during shower rinsing. By supplying water to the laundry in the washing and dewatering tub in the form of a shower from the shower nozzle, rinsing can be performed efficiently, achieving satisfactory rinsing performance and saving water. In Further, when the water supply to the washing and dewatering tank, in order to perform water supply to the first and second feed means are operated simultaneously, it is possible to shorten the water supply time.

ことができる。Further, when the operation is set by the operation display means, the control means simultaneously operates the first and second water supply means when supplying water to the washing and dewatering tub, and supplies water when rinsing the shower. Since the water supply means is operated to supply water, it is possible to select whether to supply water simultaneously with two water supply means or to supply water alone by operating the operation display means.If the tap water pressure is low, the water supply time is reduced. In addition to shortening, when the tap water pressure is high, water can be supplied only by a single water supply means, and splashing of water in the supply water due to high water pressure can be prevented.

給水中の水の飛び散りを防止することができる。Further, the control means detects the water level rising time during the water supply process by the water level detecting means. If the water level rising time exceeds a predetermined value, the first and second water level are supplied to the washing and dewatering tub. The water supply means is operated at the same time to supply water, and the second water supply means is operated at the time of shower rinsing to supply water, so that the tap water pressure can be estimated by detecting the water supply speed, and the water supply time is slow. In this case, it is possible to reduce the water supply time by operating the two water supply means without bothering the user or the service person, and to prevent water from being scattered in the water supply due to high water pressure.

煩わしさをなくすることができる。Further, there is provided storage means for storing the operations of the first water supply means and the second water supply means, and the control means supplies water to the washing and dewatering tub based on the contents stored in the storage means. Sometimes, the first and second water supply means are simultaneously operated to supply water, and the second water supply means is operated during shower rinsing to supply water. Therefore, in a home where the tap water pressure is low, this setting must be stored once. Thereafter, since the water is automatically supplied by the two water supply means, the trouble of setting each time can be eliminated.
