  • Patent number: 7886373
    Abstract: Provided is a method of controlling temperature of warm water of a bidet. The method includes: a first step of detecting a current temperature of warm water stored in a storage tank; a second step of gradually adjusting intensity of power supplied to a heating means depending on a difference when the current temperature of the warm water is lower than a target temperature; and a third step of cutting the power supplied to the heating means when the current temperature of the warm water is equal to the target temperature after the second step. Therefore, the warm water can be precisely maintained at a set temperature by checking a temperature of cleaning water in a storage tank using a sensor in real time, and gradually controlling intensity of power supplied to a heating means on the basis of the checked water temperature.

  • Patent number: 7500275
    Abstract: Provided is a power saving device using a toilet seat cover of a bidet. The device includes: a toilet seat cover sensor for detecting whether the toilet seat cover is opened or closed and outputting an electrical signal corresponding the detected result; and a control means for controlling the toilet seat and the warm water to be at low temperatures on the basis of the detected result of the toilet seat cover sensor when a power saving mode is OFF and the bidet is not used. Therefore, it is possible to remarkably reduce power consumption of the bidet during a standby mode.

  • Patent number: 7428758
    Abstract: A user controlling coin operating bidet assembly is comprised of a coin handling system with a coin collector box and an electrically operating bidet. The coin handling system contains optical coin validator, solenoid valves, coin flaps, optical coin counter, electronic timer, and microprocessor controlling those parts according to the signals triggered by the coins inserted. The electronic timer receives signal from the microprocessor and supplies power to another solenoid valve and a warm air blower connected to the bidet. A switch for selecting water and air is attached on the control panel of the bidet. 25 cents coin allows 30 seconds operation. Additional 25 cents inserted within 30 seconds extends the operation time for another 30 seconds. Emergency “HOLD” switch placed on the control panel holds the power to the bidet and stops the electric timer. Pressing “RESET” switch on the control board returns the bidet in a continuing mode.

  • Patent number: 7191473
    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.
