Working Principle Of Electric Kettle

Working principle of electric kettle:

About 5 minutes after the electric kettle is connected to the power supply, the water temperature gradually rises to 100 degrees, and the water starts to boil. If the steam switch fails, the water in the pot will continue to burn until the water is boiled dry, and the temperature of the heating element will rise sharply. There are two bimetallic plates at the bottom of the heating plate, and the temperature will rise sharply due to heat conduction, expand and deform, and break. Turn on the power. Therefore, the safety protection device of the electric kettle is designed very scientifically and reliably. This is the triple safety protection principle of the electric kettle.

Electric kettle insulation principle:

Most of the electric kettles with heat preservation function have two heating tubes, one of which is controlled separately by the heat preservation switch, which allows the user to control whether to keep heat or not. The heat preservation power is generally below 50W, and the power consumption usually does not exceed 0.1 kWh per hour.

Key components: The key component of the electric kettle is the thermostat. The quality and service life of the thermostat determine the quality and service life of the kettle. Thermostats are divided into: simple thermostat, simple + jump thermostat, waterproof, anti-dry thermostat. Consumers are advised to purchase waterproof and anti-dry thermostat electric kettles.

Other components: In addition to the key temperature controller, the composition of an electric kettle must include these basic components: the button to open the kettle, the top cover of the kettle, the power switch, the handle, the power indicator light, the heating plate, etc.

Electric kettle safety protection:

1. Automatic power off for dry burning and automatic power off for boiling water are safer;

2. Practical plastic parts should be PP food-grade materials:

3. The power cord should be high temperature resistant copper wire;
