The range hood is also called as a range hood, is arranged above a cooking range, can rapidly pump away waste gas generated by combustion of the cooking range and oil smoke harmful to human bodies in a cooking process, and is discharged to the outside, so that air pollution of a kitchen is reduced.
In the existing range hood structure, a multi-wing type forward centrifugal fan is generally adopted, and the fan has the characteristics of providing larger air quantity and air pressure at a lower rotating speed and changing the moving direction of fluid by 90 degrees. The traditional range hood is characterized in that the fan is directly arranged above a smoke cage cavity of the range hood, the oil smoke is sucked into the fan at an angle of 90 degrees with the axial direction of the fan, and then is thrown out of the fan after being turned by 90 degrees again due to the action of the rotation centrifugal force of the fan, so that the flow loss is large, the internal vortex is more, and the noise is increased. According to the design of most of the existing house flues, the traditional house flues are all arranged above the ceiling, generally between 2.6 and 2.8 meters, and are all connected into the public flues through transverse inlets, so that when a user cooks dishes in a kitchen, smoke generated by the user passes through the smoke machine and then is discharged into the public flues after the smoke machine is changed by 90 degrees above the smoke machine. In summary, for the conventional smoke machine, the smoke must undergo a change of flow direction of 90 degrees for 3 times before entering the common flue, resulting in huge flow loss and vortex, and further unnecessary noise.
For this reason, some manufacturers try to smoke in a form of externally arranging a fan (outside a house) aiming at the situation that the range hood is noisy in operation. The technology is connected with the indoor smoke collecting cavity through the external strong fan and the longer smoke pipe. Although this split external blower scheme can greatly reduce the noise generated by the smoke machine, the disadvantages associated with this are also more apparent, such as: 1) The installation is extremely inconvenient, especially for high-rise commodity houses or apartment users, and requires very specialized personnel to install, and the installation cost is very high, for example, the indoor smoke gathering cavity must be fixed to the cavity wall through the installation bracket. 2) The smoke tube connected to the room can be very long, and the resistance of the pipe is large, resulting in a great discount of the suction force. 3) The commodity building users have larger influence on other similar households; 4) Because the fan is installed outdoors to most is in the sky, lead to fan system unable washing, long-term because the effect of greasy dirt can drop by a wide margin the performance of whole fan system and lead to smoke evacuation effect to be poorer and worse.
