Problems solved by technology

The disadvantage of this technology is that it is difficult to cut off the power when the temperature of the liquid rises to the boiling temperature. In practical applications, it often occurs: either the liquid is not boiled and the power is turned off to stop heating, or the liquid is already boiling and the power is continued to be heated. The reasons are as follows:
[0004] 1. Factors such as the sensitivity of the temperature sensing element, the thermal resistance between the temperature sensing eleme

Abstract

Disclosed are a method and a device to detect and control boiling liquid, comprising a sound generator, a sound receiver and an electric circuit board; the sound generator is arranged on a container for holding liquid; when the liquid is heated to boiling temperature, the generated steam enables the sound generator to make a sound; when the sound receiver receives the voice signal, the voice signal is converted into an electrical signal, and the power supply of an electric heater is cut off through the electric circuit board. Compared with the prior art, the device of the invention has the advantages that when the liquid is heated, the liquid temperature can rise to the boiling temperature; after the liquid is boiled, the power supply of the electric heater is automatically disconnected and fives a voice alarm, so the device is safe in use; besides, as the containing for holding liquid has no electrical component, the container is easy to be cleaned.

Description

Technical field [0001] The invention relates to the technical field of liquid heating control, in particular to a method and device for detecting and controlling liquid boiling. Background technique [0002] Known techniques for controlling liquid boiling are: [0003] The first technology: use a thermostat to control the boiling temperature of the liquid, that is, set a thermostat on the vessel containing the liquid. When the temperature of the liquid rises to the temperature controlled by the thermostat, the thermostat will take off and disconnect the main circuit. . The advantages of this technology are: simple structure, low cost, and many applications. For example: the hot tank for heating drinking water in a water dispenser usually adopts this technology, and the "hot water" used to heat drinking water in a thermos bottle also has products using this technology. The disadvantage of this technology is that it is difficult to cut off the power when the temperature of ...
