Some people are used to turning on the lights in the kitchen when cooking, but it is enough to use the low-power lighting equipment on the range hood, which can make full use of the functions of the range hood and save electricity.
In fact, the range hood consumes the most power when it is started. When using a small fan, it costs electricity to start because of its slow running speed, and when using a large fan, it saves electricity because of its fast running speed. So when starting, it's best to turn on the gale first and then turn it down.
Some people use range hoods as ventilation equipment, and commonly use range hoods to dispel peculiar smells. In fact, the range of ventilation of the range hood is small, the ventilation effect is slow, and it will consume more electricity.
When cooking, many users only turn off the range hood for a few minutes, which can't play its role. The correct way to use it is to open it at the beginning of cooking and close it after 5 ~ 6 minutes.
