Temperature-controlling switches utilizing shape-memorizing alloy for electric boiler



The utility model relates to an automatic temperature control element for an electric water heater. The shape memory alloy is adopted as the temperature-sensing element material; the utility model is composed of a shape memory alloy element chamber and an electric chamber and is designed according to the principle that the stress restricts the phase change or the heat expansion generates the heat-sensing quick action effect. The utility model is suitable for the temperature control of the electric water heaters in different areas and can avoid effectively unfavorable outcomes that the water is not boiling because of the fact that the power is switched off, or the water is boiling but the power is not switched off. The utility model has the advantages of simple structure, low cost, and reliable operation.
