Several Knowledge about Range Hood

Tips for the maintenance of range hood

We are likely to use the range hood in the kitchen every day, and we may come across the situation of excessive vibration and noise of the hood, the fumes cannot be spared as well as drop of oil and the oil spill in the process of using. Now let look at some basic common sense in the maintenance: first, the height of hood installation must be appropriate, including the Isaland hood. And this would ensure the range hood not to be touched by our head, but also ensure that the effect of fume extraction. Second, in order to avoid the voice of the hood or too large vibration and the occurrence of oil spills and other situations, we should regularly clean the hood to avoid excessive viscous oil on the surface of motor, turbine and hood. Third, keep the air circulation in the kitchen, so prevent formation of negative pressure to ensure that the pumping capacity of the hood. Fourth, the consumer should better not to disassemble the hood for cleaning, because once the motor is not installed well, and the smoking effects cannot be guaranteed, and will increase the noise.

Classification of range hood

The hood is the appliance for family kitchen to absorb the cooking fumes. At present, the hood can be divided into two categories: European-style and Chinese style. European-style hood is mainly the wall mount hoods and a part of the island high-end products; the Chinese style is mainly the wall-mounted hood. Range hood consists of fan system, control system, filtration system shell and suspension device. The fan system is the heart of the hood, and it usually consists of the motor and impeller. The size of the power is determined by the fan system. The control system is an integral part with the scientific and technological content and it has micro-board power and switch control hood. Filtering equipment mainly refers to the network and the oil filter cavity. Shell and suspension device are created by high-temperature corrosion-resistant materials, such as stainless steel.

Hood principle can be summed up as follows

First, the running motor drives the rotation of coaxial linking the impeller. Second, the rotation and agitation of the impeller make the fan blades produce the rapid updraft. Third, airflow forms the vortex negative pressure zone in the vicinity of the air inlet, so that the fumes from the gas rise rapidly. Fourth, when the fumes run to oil net, it will create rotation friction and make the separation of fumes. Fifith, when there is a certain amount of grease oil accumulated to net, and it will flow into the oil cup due to the force of gravity.
