  • Publication number: 20030140407
    Abstract: When a user sets water power using a water power adjustment switch in a remote control device, a controller controls the period of pressure fluctuations, the width of pressure fluctuations, and the central pressure of the discharge pressure of a pump on the basis of a signal transmitted by radio from the remote control device. When the user sets the divergent angle of washing water using a washing area adjustment switch in the remote control device, the controller controls the divergent angle of the washing water sprayed from a posterior nozzle on the basis of the signal transmitted by radio from the remote control device. Consequently, the washing water supplied to a side surface of a cylindrical swirl chamber from a first flow path in the posterior nozzle is sprayed from a spray hole as dispersed spiral flow, and the washing water supplied to a lower part of the cylindrical swirl chamber from a second flow path in the posterior nozzle is sprayed from the spray hole as linear flow.

  • Publication number: 20020040500
    Abstract: The water shower apparatus according to the present invention is constructed in a way to produce cold air intercepting screen having warming effects around the bather. In this water shower apparatus, the shower sprayed from the wide-angle spray nozzle of the shower system forms a shower curtain. That water shower of thin cold air intercepting screen is sprayed toward about the neck and the shoulders to the flanks of the bather. And, the shower curtain formed this way wraps about the horizontal face under the neck of the bather, the vertical face about in the vertical direction on the left and the right sides of the bather's body, and the front face centering on the lower half portion of the bather's body. This enables to intercept cold air from outside and enclose the hot air inside. Production of “cold feeling” at the time of entry of the bather into the chilled bathroom can be prevented. The entire body of the bather can be warmed with bathing.
