The process principle of electric kettle

Electric kettle is a common small household appliance, and its process principle mainly includes the following steps:

Heating element: There is a heating element inside the electric kettle, usually using a heating coil made of metal or alloy materials. When the power is turned on, the current generated by the heating element flows through the wire through the coil, causing it to generate resistance and convert it into heat energy.

Heat conduction: The heat energy generated by the heating element will be transmitted to the water supply through conduction. In the design of an electric kettle, the heating element is usually located at the bottom of the kettle and in direct contact with the water in contact. Through the conduction effect of the metal base, thermal energy is transferred from the heating element to the water at the bottom.

Temperature control: Electric kettles are usually equipped with a temperature control system to control the heating process. The system detects the temperature of water through temperature sensors and transmits the data to the control circuit. According to the set temperature, the control circuit will automatically adjust the size of the current passing through the heating element to maintain the water temperature within the set range.

Boiling protection: In order to prevent water from overheating and causing safety issues, electric kettles are usually equipped with boiling protection devices. When the water temperature rises to the boiling point, the boiling protection device will automatically disconnect the power supply of the heating element and stop the heating process. This can prevent further heating of the water from causing it to boil, dry burn, and damage.

Safety measures: In addition to boiling protection devices, electric kettles also have other safety measures. For example, there is usually a safety lock on the lid of a kettle, which can only be poured or filled with water when it is closed and locked. In addition, some electric kettles are also equipped with anti dry burning functions. If there is no water in the pot, the heating element will automatically disconnect the power to avoid damage.

In summary, the process principle of an electric kettle is to convert electrical energy into thermal energy through heating elements, and then transfer the thermal energy to water supply through conduction. Temperature control and safety measures ensure precise control and safety during the heating process. These principles enable electric kettles to quickly and conveniently heat cold water to the desired temperature, meeting people's daily life and drinking needs.
