Title:
水流ヒーター
Document Type and Number:
Japanese Patent JP5793277
Kind Code:
B2
Abstract:
Water flow heater with a first heater element (20) for supplying a fixed power, a second, controllable heater element (30), a temperature sensor (40, 50) for measuring the temperature of heated water, and a control unit (22, 32, 80) for controlling the heat supply from the second heater element (30) in dependence on a temperature detected by the temperature sensor (40, 50). A water flowrate lying within a predetermined range is safeguarded in that a pump (60) is provided for generating a water flow through a channel (13), and the control unit is designed so as to activate the heater elements (20, 30) in dependence on activation of the pump (60). As a result, the first heater element (20) of fixed power can have a comparatively high power rating without the risk of water being too strongly heated thereby.
