High-efficiency low-power consumption electronic controller used for dust collector

Abstract

The invention discloses a high-efficiency low-power consumption electronic controller used for a dust collector. According to the high-efficiency low-power consumption electronic controller disclosed by the invention, a voltage value signal acquired by a voltage acquisition unit, a current value signal acquired by a current acquisition unit and a zero value signal acquired by a zero passage acquisition unit are received by adopting a single-chip microcomputer, and are transmitted to a motor drive unit after operation processing is performed on the signals, and by combining a fuzzy control algorithm in the single-chip microcomputer, constant-power control is realized, and the goal that no matter what condition the dust collector is, the total power maintains at the power value of the maximum efficiency point or other power values is achieved. Thus, under the condition that the suction power of the dust collector is not reduced, the input power of the dust collector can be reduced, and the goals that the energy is saved and the energy efficiency is improved are achieved.

Description

technical field [0001] The invention relates to an electronic controller with high efficiency and low power consumption for a vacuum cleaner. Background technique [0002] Existing household vacuum cleaners use the vacuum (negative pressure) generated by the high-speed rotation of the electric fan to collect dust, garbage, etc., to achieve the effect of cleaning the environment. During the use of the vacuum cleaner, the state of the suction port will change randomly when the suction port is in contact with the place to be cleaned, so that the air flow or flow rate in the suction machine will also change accordingly. When the suction device leaves the place to be cleaned, the surface of the suction port is opened, the air flow increases, the air density in the vacuum cleaner cabin is relatively high, and the motor load is large, which makes the power of the electric fan inside the machine larger; when the suction port is close to the place to be cleaned, the suction port The...

AI Technical Summary

Problems solved by technology

[0003] By analyzing the characteristics of this fan, we can find such a problem: when the vacuum cleaner is sucking dust, because the suction device is close to the place to be cleaned, the power of the fan at this time will decrease; When cleaning the place, the power of the fan at this time will increase instead

In other words, when the vacuum cleaner is not cleaning during operation, the power consumption of the motor will be greater.

Therefore, the above-mentioned fan characteristics are not energy-saving
