Problems solved by technology

At present, the common range hoods on the market can only operate at a preset gear with a fixed air volume. When the cooking mode changes, if the user fails to switch the gear in time, it will inevitably cause a large amount of oil fume to escape and pollute the indoor environment. , it is difficult to meet consumers' pursuit of green environmental protection, noise reduction, energy saving and intelligence

Abstract

The invention discloses an extractor hood with automatically controlled gears. The extractor hood with automatically controlled gears is characterized by comprising an exhaust fume collecting hood body, a control system, an exhaust fume probe, a temperature sensor and a motor, wherein the exhaust fume probe and the temperature sensor are installed on the exhaust fume collecting hood; and the control system changes the rotation speed of the motor according to signals fed back from the exhaust fume probe and the temperature sensor. The generation and escape conditions of exhaust fume can be accurately mastered, the gears and air volume of the extractor hood can be automatically controlled along with change of the concentration of the exhaust fume, the both hands of people are liberated, the intelligence degree is high, and the exhaust fume extraction effect is good. Meanwhile, the air volume of the extractor hood is changed along with change of the exhaust fume amount, pollution of the exhaust fume to the exhaust fume probe is effectively reduced, the service life of the exhaust fume probe is prolonged, and the pursuit of customers for environment protection, noise reduction, energy conservation and intelligence is met.

Description

technical field [0001] The invention relates to the technical field of kitchen oil fume removal, in particular to a range hood with automatic gear control. Background technique [0002] The range hood is a very common kitchen oil fume removal device. It forms a negative pressure zone in a certain space above the stove, sucks, filters, and purifies the indoor oil fume gas and then discharges it outdoors. At present, the common range hoods on the market can only operate at a preset gear with a fixed air volume. When the cooking mode changes, if the user fails to switch the gear in time, it will inevitably cause a large amount of oil fume to escape and pollute the indoor environment. , It is difficult to meet consumers' pursuit of green environmental protection, noise reduction, energy saving and intelligence. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a range hood that can automatica...
