Problems solved by technology

When the fan is powered off and shut down, the separation efficiency of the air flow in the cyclone separator decreases with the decrease of the fan speed, causing the dust to pass through the pre-filter due to the reduction of the separation efficiency during the shutdown process, and the fan speed decreases. The suction of the fan is weakened, resulting in a large amount of dust not passing through the pre-filter at a sufficient speed and adhering to it, thus affecting the cleaning efficiency of the re-work

Abstract

The invention provides a fan control method and system. The control method includes: a control circuit receiving a control instruction from a controller; triggering the opening and / or closing of at least part of the control elements in the control circuit according to the control instruction, so that the current in at least one coil of the fan is reversed circulation. The method can shorten the downtime of the fan and realize sudden stop.

Description

Technical field [0001] The present invention relates to the field of fan technology, and in particular, there is a fan control method and system. Background technique [0002] The working principle of the vacuum cleaner is that the fan drives the impeller, and the air is done, and the air in the dust barrel is extracted to form a pressure difference in the barrel to the atmospheric pressure, thereby sucking the object around the air inlet into the dust barrel. In the existing vacuum cleaner, a front filter is provided in the middle of the fan and the cyclone, which is used to filter the airflow from the cyclone into the fan. When the wind turbines are disconnected, the airflow separation efficiency decreases with the wind turbine speed, resulting in dust in the shutdown process through the front filter due to separation efficiency, and the fan speed is lowered. The fan suction is weakened, causing a large amount of dust that is not enough to pass through the front filter, thereby...
