<p>PURPOSE:To permit stable control with a reduced time element of delay in hot-water temperature control system by a method wherein a heat exchanger is installed near a hot-water discharging nozzle as closed as possible and the heat exchanger is provided with a discharging hot-water temperature controlling thermistor at the outlet port thereof. CONSTITUTION:Hot-water, discharged out of a hot-water discharging port 12 provided on the lid 11 of a hot-water reserving tank 6, is introduced by a hot-water discahring path 13 into the heat exchanger 18, having a heat exchanging flow path 17 provided with an electric heater 14, an inflow port 15 and an outflow port 16. A thermistor 19 is provided near the outflow port 16. The flow of the hot-water from the outflow port 16 is selected by a flow path switching unit 20 whether the flow is connected to a cleaning nozzle 21 or is connected to a circulating and heating flow path 22 circulating and heating the hot-water in the hot-water reserving tank 6. The temperature of hot-water heated by the electric heater 14 is detected immediately by the thermistor 19 provided near the outflow port 16, therefore, stable hot-water temperature control may be effected. Further, the flow path from the outflow port 16 of the heat exchanger 18 to the cleaning nozzle 21 can be set so as to be sufficiently short, therefore, the delay of response due to remaining water in the flow path may be improved remarkably.</p> |
