Embodiment 1

[0016] Such as: range hood, exhaust fan

[0017] The method of the invention consists of a hollow ring stator, two hollow ring rotors and six rotary vane coaxial bearings to form a suction and discharge motor fan.

[0018] The high-efficiency suction and discharge hollow ring shaftless motor fan is used, and the motor is used as power to drive the rotating blades to form an energy-saving suction and discharge hollow ring fan.

[0019] 2 hollow ring rotors are connected in parallel with 6 rotors and the inner wall of the coaxial bearing is driven by 5 ring wall rotors to form a rotating suction and exhaust fan device; 2 hollow ring rotors are connected in parallel with 6 rotors and the inner wall of the coaxial bearing is energized through the outer wall of 7 bearings and 1 hollow ring stator to generate magnetic field line cutting. The rotation pushes the 5 ring wall rotary vanes to work.

[0020] 1. The hollow ring stator is connected to 7. the outer wall of the bearing and ...

Abstract

The invention discloses a suction and exhaust motor fan composed of a hollow ring stator 1, a hollow ring rotor 2 and a rotary vane coaxial bearing 6. The fan is composed of the hollow ring stator, the hollow ring rotor, a hollow ring fixing support, the tangent air opening input direction, ring wall rotary vanes, the inner wall of the rotary vane coaxial bearing, the outer wall of the bearing, the exhaust output direction and the rotary vane rotating direction. The hollow ring rotor 2 and the inner wall of the rotary vane coaxial bearing 6 are connected in parallel to drive the ring wall rotary vanes 5 to form a rotary suction and exhaust fan device. The hollow ring rotor 2 and the inner wall of the rotary vane coaxial bearing 6 are connected in parallel and powered with the hollow ring stator 1 through the outer wall 7 of the bearing to generate magnetic lines of force for cutting to form rotation to push the ring wall rotary vanes 5 to work. The hollow ring stator 1, the outer wall 7 of the bearing and the hollow ring fixing support 3 are connected to form a fixing device.

Description

technical field [0001] The patent of the present invention relates to an energy-saving suction-exhaust hollow ring fan and other multi-field motor fans for suction and exhaust, especially to an energy-saving suction-exhaust hollow ring fan; it is used for barrier-free vacuum cleaners, road sweepers, suction and exhaust, and non-corrosive range hoods; Energy-saving hollow ring motor fans (referred to as "high-efficiency suction and exhaust hollow ring shaftless motor fans") that can be applied to hair dryers. Background technique [0002] Based on the fact that the existing motors are all shaft motors, the center shaft carries a large torque, and the preconditions are oily smoke, high temperature, high humidity, easy corrosion of the motor, and large power consumption. Contents of the invention [0003] The key innovation points of the present invention: 1: barrier-free suction and discharge; 2: oil fume and no corrosion motor; 3: no friction dead angle on the rotating inne...
