Correlation knowledge of electric kettles Electric kettles are popular among consumers because of their fast and convenient boiling water. They are the necessary electrical products in modern kitchens, especially for homes like tea, coffee, drinks, etc. However, many consumers do not fully understand the electric kettle. In this article, Jiu Zhengxiao compiled some relevant knowledge about electric kettles, hoping to help more consumers understand the electric kettle.
1, the working principle of the electric kettle
The working principle of the electric kettle is actually very simple. It uses the water vapor generated when the water boils to deform the bimetal of the steam sensing element, and uses the principle of the lever to push the power switch, so that the electric kettle automatically rotates after the water is boiled. Power off. The power failure is not self-resetting, so the kettle will not automatically reheat after the power is turned off.
2. Triple safety protection device for electric kettle
The first weight: steam switch, when the water boils, the steam switch will act to make the kettle power off; the second weight: dry burning protection, if the steam switch does not move, the water will continue to burn and continue to decrease, when the water is below the minimum When the water level is dry or dried, another bimetal on the temperature control will act to de-energize the kettle; the third weight will lose its effect as above, and as the temperature rises, a plastic pusher in the thermostat will melt. To de-energize the kettle.
3. Advantages and disadvantages of electric kettle compared with other electric drinking water equipment
advantage:
1, water 100% boiling 2, clean and hygienic, how much to burn, no overnight water 3, convenient, fast, can be used 4, beautiful appearance, can be home decoration and can be used as a gift of shortcomings:
1, most do not add insulation design 2, usually use tap water directly
4, the principle of electric kettle insulation, whether it consumes electricity when it is insulated
Most of the kettles with heat preservation function have two heat pipes. One heat insulation tube is separately controlled by the heat preservation switch. It allows the user to control whether the heat is kept continuously. After reaching a certain time, the water temperature can still be maintained. Suitable temperature for instant noodles, etc. Insulation is generally below 100W, and it usually consumes no more than 0.1 kWh per hour.
