ABSTRACT:
An alarm which can be used in lieu of the knob of the cover of a teapot or an ordinary pot which provides the capability of sounding a musical alarm when the water temperature inside the teapot or kettle nears the boiling point. The alarm contains a body member, an upper plate, a sensor, a speaker and an electronic assembly. The sensor detects the vapor temperature variations in a teapot through a sensing plate beneath the teapot cover and produces an electrical signal corresponding to the vapor temperature level. This signal is then changed to musical sounds through an electronic assembly when the water nears its boiling point.
