Title:
A LIQUID HEATER WITH AN ALARM
Document Type and Number:
WIPO Patent Application WO/2005/055785
Kind Code:
A1
Abstract:
The present invention relates to the technical field of electrically heating. Specifically it discloses a liquid heater which comprises a container, an electric heating element and a temperature controller. It solves the problem that water will get cooled or be reheated over again after a certain period of time since being boiled, because the working conditions of the existing electric kettles are not available after their power sources are cut off. The present invention also solves the problem that continuative heating behavior and fire will occur after water is boiled in the case that the temperature controller fails. Said liquid heater comprises a container (1), an electric element (2) disposed on the container and an electric temperature controller (3). Said electric element (2) and electric temperature controller (3) are connected in series in the circuit of the power source. An alarm temperature controller (4) is disposed on the container (1) for sensing the temperature thereof A sounder (5) is disposed in the series circuit of said alarm temperature controller (4) and the power source. Since the heater is provided with the alarm temperature controller on the container and the sounder in the series circuit of said alarm temperature controller and the power source, the power source will be cut off and the alarm will be given by sensing the steam produced. The alarm will be stopped after users are warned for a period of time.
