Abstract

The invention discloses a DC frequency conversion range hood. The DC frequency conversion range hood comprises a range hood main body, a control system and a motor (3) connected with the control system, and is characterized in that: the motor (3) is a three-phase brushless DC permanent-magnet motor; the control system is a frequency conversion system which consists of an inductive control panel (1), a frequency conversion controller (2) and the motor (3); the inductive control panel (1) is connected with the frequency conversion controller (2) through a communication cable; the motor (3) is electrically connected with the frequency conversion controller (2); and a Hall position sensor arranged on a stator of the motor (3) is connected with the frequency conversion controller (2) through a circuit. The DC frequency conversion range hood improves efficiency and reduces energy consumption due to the DC frequency conversion driving; moreover, inductive control can be realized, so operation is more convenient and faster and the comfort of using the product is also improved.

Description

technical field [0001] The invention relates to a range hood, in particular to a DC frequency conversion range hood. Background technique [0002] At present, energy saving has become the development direction of home appliances in the future. The range hoods and smoke exhaust fans used in people's daily life are generally AC motors. Range hoods are also electrical appliances that are used every day in the family. , although the time of use is not long each time, the energy consumption is still very large due to the low efficiency of the AC motor currently used. Even if some have introduced the frequency conversion technology into range hoods, the existing products can only achieve three-speed speed regulation, and the speed regulation gears are too few. Since the stepless speed regulation cannot be achieved, it cannot satisfy the user's random choice of speed Requirements, not convenient and comfortable enough in use. Contents of the invention [0003] The purpose of th...
