Floor fan is a kind of electric fan, the air volume is large, low noise is its main characteristics, widely used in home, warehouse, workshop, restaurant. Today we introduce the working principle of floor fans and the use of safety instructions, may wish to understand oh.
First, the working principle of the floor fan
The main component of the floor fan is: AC motor, that is to say, the motor is the heart of the floor fan. Floor fans and electric fans work on the same principle: an electrically charged coil is rotated by force in a magnetic field. The form of energy conversion is: electrical energy is mainly converted into mechanical energy, and because the coil has resistance, it is inevitable that part of the electric energy will be converted into heat energy.
2. Safety precautions for floor fans
In the electric fan electrocution death accident, the biggest harm is the floor fan, and easy to develop into a group injury accident. This is because the floor fan high center of gravity, charged mobile, adjust the hands must hold the pillar, in case of floor fan insulation damage or due to improper wiring shell when charged, get an electric shock the spasm of hands must hold poling usually floor fan pressure in human body on the ground at the same time, make people can't get rid of electric shock, group of injury accidents caused by improper rescue. Therefore, the use of electric fans must be strictly done the following safety measures:
1. Do not move the electric fan with power on. Cut off the power supply and wait until the wind blade stops rotating before moving. This is one of the most critical safety measures.
2. According to the housing area, the number of household appliances, reasonable arrangement of the power socket (number, layout), do not temporarily connect the long power cord,
To eliminate electrical accidents caused by wiring errors.
3. To purchase qualified products, please ask electrical personnel who know how to inspect the products assembled by oneself or assembled by informal electrical factory to eliminate defects.
4. The electric fan enclosure should be grounded reliably.
5. Before new purchase, repair or annual use, the electric pen must be used to check the electric fan shell without leakage phenomenon.
6. Household shock protector should be installed.
