<p>PURPOSE:To facilitate an easy setting of a hot water heater and to enable a required amount of hot water to be supplied in a less-expensive manner by a method wherein a heating source is disposed within a hot water storing tank having a capacity required for one time use, a water feeding port connected to a plug is disposed at a lower part of the tank and a hot water feeding pipe is disposed at an upper part. CONSTITUTION:Water from a plug 17 enters an outside part partitioned with a partition plate 12, flows from a flowing-in hole 13 at a lower side into a hot water storing tank 11. A signal detected by a temperature sensor 20 is transmitted to an electronic circuit 24, an electric power at a heating source 19 is controlled. As hot water reaches such a temperature as one suitable for its use, a displaying lamp 26 is lit. Under this state, as a hand is approached near an outlet of a hot water feeding pipe 21, this is detected by a human body sensor 25 and a solenoid valve 22 is opened only for a time in which it is detected or only for a time in which a specified period of time elapses with a timer after detection. With such an arrangement, hot water within the hot water storing tank 11 is flowed out through a hot water feeding pipe 21 with water supplied from the plug 17. With such an arrangement as above, it is possible to supply hot water of required amount suitable for one time use such as hand washing and so it is not necessary to get a special installing place.</p> |
