Introduction of working principle and maintenance of electric kettle

Electric kettle uses the principle that electric energy is converted into heat energy to heat water. Now, most people start to use electric kettles at home. Electric kettle is much more convenient, safe and reliable than traditional gas-fired water heating. What is the working principle of electric kettle? The working principle of electric kettle is simple, but it also needs maintenance during use. Today, Bian Xiao will introduce you to the working principle of electric kettle. You can learn about the maintenance and working principle of electric kettle.

First, the working principle of electric kettle

The working principle of the electric kettle is that the steam generated when the water boils deforms the bimetal of the steam temperature sensing element, and the power switch is pushed by the deformed lever principle, so that the electric kettle is automatically powered off after the water boils. Its power failure can't be automatically reset, so the kettle won't be automatically reheated after power failure. Using PTC heating element instead of heating tube can effectively prevent the fire danger caused by dry burning. The dry burning temperature of PTC heating element can be set at any temperature between 150℃ and 250℃. When the temperature reaches the set temperature, the resistance of PTC element increases rapidly, and the heating power drops sharply, keeping its temperature at the set temperature and not rising any more.

Second, the electric kettle maintenance and maintenance

1. The rated power of electric kettle is generally large, and the capacity of power plug, socket and power cord should be selected appropriately. Generally, the specification of 10A should be selected. If the rated power exceeds 2200W, a larger socket should be used. In addition, the socket should be used independently to ensure safety.

2. The plug of the electric kettle generally has a grounding electrode, and it should be connected to the socket with a grounding socket. When in use, the power plug should be completely inserted into the socket.

3. Keep the power plug, socket, power cord and automatic switch device of the electric kettle dry and clean.

4. Water injection should not exceed the highest water level line, so as to avoid overflow when the liquid is boiling. But not too little, so as not to cause dryness.

5. When using the electric kettle, don't let the children touch the kettle body or the power cord to avoid accidents such as burns.

6. When cleaning, the electric kettle should not be immersed in water or washed with water, so as to avoid damage to electrical insulation due to humidity, resulting in failure and leakage.

7. Don't repair the electric kettle yourself. In the process of use, if the electrical appliance is damaged and can't work normally, don't disassemble the shell for maintenance, but send it to the repair shop or product manufacturer for maintenance.

Pay attention to safety when using electric kettle, because electric kettle uses electricity, and improper operation may easily lead to circuit burning. The electric kettle can't be opened when there is no water, otherwise it will dry up and easily damage the electric kettle. When we buy electric kettles, we should also buy some ones with higher safety level. In addition, do not exceed the water level line when adding water, which will easily lead to boiling of liquid.
