A range hood with air volume adjustment function

Abstract

The invention discloses a range hood with an air regulation function. The range hood comprises a body, a sensor group, an air channel, an operation panel, a controller, a direct current motor and fan blades, wherein the air channel, the operation panel, the controller, the direct current motor and the fan blades are installed on the body. The range hood is characterized in that the sensor group is arranged, the controller comprises a central processor, the sensor group is installed at an air inlet, detects oil smoke and vapor concentrations at the air inlet during operation of the range hood and feeds back the oil smoke and vapor concentrations to the central processor, and the central processor carries out integrated computation so as to obtain an air volume value and controls the revolving speed of the direct current motor. The range hood provided by the invention overcomes the problem that a conventional range hood cannot integratedly handle influence of a kitchen environment and shared flues on oil smoke absorption effects and has the advantages of noise reduction, energy conservation and environment friendliness.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood with the function of automatically adjusting the air volume. Background technique [0002] In the prior art, range hoods generally only have two or three air volume keys. When the motor speed is set, the motor will not adjust the range hood air volume and air pressure according to the actual kitchen environment or cooking method, so that it can be adjusted at any time. Adapt and be in the most reasonable working condition. For example, the air volume required for steaming and stir-frying is different. Generally, high air volume is not required for steaming. If you turn on the highest speed gear during steaming, it will cause unnecessary waste of electric energy. The oil fume or water vapor that is often produced during the cooking process changes at any time. The existing range hoods will not actively detect this change, and adjust the motor speed to change the air volume...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a range hood with a reasonable structure, which can automatically detect the kitchen environment, cooking methods, air volume and pressure, and adjust the air volume and pressure, which solves the problem that cannot be considered comprehensively in current products. The problem of the influence of the kitchen environment and public flue on the effect of range fume
