Method of detection the boiling moment of a liquid and the device for detection of the boiling moment of a liquid

摘要

The invention concerns a method of detection of boiling moment of liquids in cooking containers heated on domestic cooking appliances characterised in that ultrasound waves are transmitted by a transmitter towards the container with liquid that is being cooked and then the reflected ultrasound waves are received by means of a receiver and compared with the transmitted waves, and the observed changes in the phase and amplitude of the received sound wave resulting from turbulence occurring during boiling of liquid indicate the boiling moment of liquid, and a device for detection of boiling moment of liquids.
