Problems solved by technology

[0003] 1. The volute fan can only enter the air from one side, resulting in poor smoke exhaust from the range hood and large resistance, which affects the smoke exhaust effect of the range hood;
[0004] 2. Since the volute fan can only enter the wind from one side, the fan operation is not stable and the noise is loud

Abstract

The invention discloses an exhaust device with a cyclone sucking air duct. The exhaust device comprises a volute, a worm gear and a driving motor, the worm gear is disposed in the volute, the driving motor is connected with the worm gear and drives the worm gear, the volute is provided with an exhaust opening and two air inlets, the two air inlets are respectively positioned on two shaft sides of the volute, fixing racks are respectively mounted at the two air inlets, output shafts are arranged on two shaft sides of the driving motor, and ends of the two output shafts are respectively mounted on the two fixing racks. By the aid of the exhaust device, a smoke discharging effect of a range hood can be effectively improved, and running of the range hood is more stable.

Description

technical field [0001] The invention relates to a hurricane suction air duct exhaust device. Background technique [0002] The drive motor (inner rotor motor) of the existing air exhaust device can only be installed behind the volute, resulting in the following defects in the existing air exhaust device: [0003] 1. The volute fan can only enter the air from one side, resulting in poor smoke exhaust from the range hood and large resistance, which affects the smoke exhaust effect of the range hood; [0004] 2. Since the volute fan can only enter the wind from one side, the fan is not running smoothly and the noise is loud. Contents of the invention [0005] Based on this, the present invention overcomes the defects of the prior art and provides a hurricane suction air duct exhaust device. The present invention can effectively improve the smoke exhaust effect of the range hood, and the operation is more stable. [0006] Its technical scheme is as follows: [0007] A hurri...
