Abstract
The invention discloses a speed governing exhaust fan controller which comprises a 220-V AC (alternating current) power supply, an exhaust fan motor M, a full-bridge rectifier circuit, a silicon controlled rectifier and a trigger circuit thereof, wherein common characteristics of exhaust fans in the market are as follows: one rotating speed of the exhaust fans is available, and the rotating speed of the exhaust fans can not be governed manually. When long-term ventilation is required in a room or closed space, the exhaust fan only works at full speed, thus electric energy is wasted, and an exhaust fan motor is easily brunt due to overheating after long-term working. The speed governing exhaust fan controller can govern the rotating speed of the exhaust fan according to the demand. When rapid ventilation is required in the room, the exhaust fan can work at full speed; and when long-term ventilation is required in the room, the exhaust fan works at low speed, thus unnecessary electric energy waste can be effectively avoided, and the exhaust fan motor can be effectively protected from being burnt due to overheating.
Description
Technical field
The invention belongs to electronic technology and air-conditioning technique field, relate to a kind of speed governing ventilating fan controller.
Background technique
The common feature of various ventilating fans is on the market: the rotating speed of ventilating fan has only a kind of speed, and manual work can't be regulated the running speed of ventilating fan.When room or confined space need long-time ventilation, can only let the ventilating fan full speed operation, so both waste electric power, also make the ventilating fan motor easily because of overheated the burning out that work long hours.
Speed governing ventilating fan controller of the present invention can be adjusted the running speed of ventilating fan as required.When the room needs ventilation fast, can let the ventilating fan full speed operation; When the room needs long-time ventilation, can let ventilating fan with lower speed operation, so both can effectively stop unnecessary power wastage, can also effectively protect the ventilating fan motor can not burn out because of overheated.
It is simple that speed governing ventilating fan controller of the present invention has a circuit, all uses common components and parts, and fabricating cost only needs tens yuan, is well suited for exploitation in batches, also is suitable for the novel exhaust fan that factory's exploitation has speed-regulating function.
Through kinds of schemes test, relatively and analyze, the present invention only uses a small amount of common discrete component, has realized that circuit structure is simple, cost is low, designing requirement such as effective, reliable working performance.
Below specify speed governing ventilating fan controller of the present invention related relevant technologies content in implementation process.
