<p>PURPOSE:To automate variable supply of hot water by providing a switching valve and temperature regulating means for varying the condition of hot water, and providing a control circuit which integrates signals from a flow rate detector and compares the integral value with a value set by integration flow rate setting means, and limits the variable hot water supply. CONSTITUTION:When only an intermittent hot water supply is to be made, an automatic hot water supply stop switch 30 is turned off, and an intermittent hot water supply switch 31 is turned on. The opening time and the closing time of an electrically driven two-way valve 24 are set by an opening time setting knob 32 and a closing time setting knob 33. By opening the cock 29 of a hot water supply tap 18, hot water made to a suitable temperature by a mixing valve 22 is intermittently supplied in accordance with the setting time. Further, when the opening time setting knob 32 is set to a short time (for example 5sec) and the closing time setting knob 33 is set to an extremely long time (for example, 1hr) and the intermittent hot water supply switch 31 is turned on, hot water supply is carried out for 5sec and then automatically stopped, and hence it is possible to automatically supply a predetermined quantity or a small quantity of hot water by the operation of the intermittent hot water supply switch 31, and to automatically stop the hot water supply.</p> |
