    • PURPOSE:To decrease the opening and closing frequency of a contact and to improve the durability of the contact by a method wherein a main heater circuit is maintained under an opening condition within a fixed range of a hot water temperature after the detection of a steam, in an electric water heater with a boiling detector. CONSTITUTION:A water is heated by electrifying of a main and an auxiliary heater 9, 10, when a water temperature rises nearly 90 deg.C, a returning thermostat switch 11 and a thermostat switch 12 of the auxiliary heater 10 are made OFF, the hot water temperature rises up 100 deg.C, the generation of a steam is started. A steam detecting thermostat switch 16 detects the generation of the steam, then the switch is made OFF. Thereby, a coil of a relay 16 is excited and the relay is made OFF, the boiling is stopped. Thereafter, the relay 16 is made self- holding and kept under opening condition even during the hot water temperature is lowered, when the temperature is lowered nearly 89 deg.C, the hot water temperature is maintained at nearly 90 deg.C by ON/OFF of the thermostat switch 12 fof the auxiliary heater 10. When the hot water temperature is lowered below 85 deg.C, the returning thermostat switch 11 is made ON, the relay 16 is closed. By such a structure, the durability of the contact can be lengthened.
    • 目的:为了降低接触的开闭频率,并且通过在检测蒸汽之后将主加热器电路保持在热水温度的固定范围内的开放状态的方法来提高接触的耐久性, 在具有沸点检测器的电热水器中。 构成:当水温上升近90度时,通过主辅助加热器9,10的通电来加热水,辅助加热器10的返回恒温开关11和恒温开关12被关闭, 热水温度上升100℃,开始产生蒸汽。 蒸汽检测恒温开关16检测蒸汽的产生,然后关闭开关。 因此,继电器16的线圈被激励,继电器断开,沸腾停止。 此后,即使在热水温度降低的情况下,继电器16自主保持并保持在开启状态,当温度降低近89℃时,热水温度保持在接近90℃, 关闭辅助加热器10的恒温开关12f。当热水温度降低到85℃以下时,使返回恒温开关11接通,继电器16闭合。 通过这样的结构,可以延长接触的耐久性。
