Low-noise and energy-saving air cleaner and working method thereof

Abstract

The invention discloses a low-noise and energy-saving air cleaner and a working method thereof, and relates to an air cleaner and a working method thereof. Currently, the air cleaner has low motor efficiency, obvious noise and large motor power consumption, is inconvenient to use and can affect the rest of a user because an alternating current motor is used and a relay is adopted to control a motor tap for speed adjustment. The low-noise and energy-saving air cleaner comprises a control system and an execution device and is characterized in that the control system comprises a sampling module,a signal receiving module, a control module, a motor driving module, a switch power supply and a manual controller; the sampling module, the signal receiving module and the motor driving module are all connected with the control module; the manual controller is a movable-type manual controller; a wireless sending module is arranged on the manual controller; the motor is a direct current brushlessmotor; a rotation speed feedback module is arranged on the motor; and the direct current brushless motor is connected with the control module through a motor driving module. The low-noise and energy-saving air cleaner has the advantages of wide application ranges, low noise, good comfort degree, stepless speed change and stable speed adjustment.

Description

technical field [0001] The invention relates to an air purifier and its working method. Background technique [0002] Current air purifiers such as figure 1 As shown, an AC motor is used, and a relay is used to control the tap speed of the motor. Only the third or fourth gear speed can be adjusted. The motor has low efficiency and obvious noise, which affects the overall performance of the purifier. Cause the whole electric motor to consume a lot of electricity, use inconveniently, work at night affects the user's rest. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, provide a low-noise and energy-saving air purifier and its working method, so as to achieve the purpose of low-noise and energy-saving. For this reason, the present invention takes the following technical solutions. [0004] The low-noise and energy-saving air cleaner i...

Problems solved by technology

[0002] Current air purifiers such as figure 1 As shown, the AC motor is used, and the relay is used to control the speed of the motor tap. Only the third or fourth gear can be adjusted. The motor efficiency is low and the noise is obvious, which affects the overall performance of the purifier.

As a result, the entire motor consumes a lot of power, which is inconvenient to use, and night work affects the user's rest
