The structure of the automatic speed regulator with a temperature controller is simple. The circuit is simple and applicable. Electricity consumption is low. Compared with the current universal reactance type speed regulator, the automatic speed regulator with a temperature controller can save 40%-80% electricity. The automatic speed regulator with a temperature controller can automatically regulate speed, and can be automatically stopped and started according to environment temperature. The universal performance of the automatic speed regulator with a temperature controller is strong. The automatic speed regulator with a temperature controller is suitable for various ceiling fans, stand fans, desk fans, fans with air flow guiding devices, exhaust fans, and can also be used for the light regulation of lamps.

Description

Automatic speed regulator with temp controller

The utility model relates to a kind of electric apparatus control apparatus, specifically a kind of temperature control automatic speed governor that is mainly used in the electric fan speed governing.

Along with the develop rapidly of national economy and the raising day by day of living standards of the people, electric fan has become the essential items of people's family daily life, work and public place, in order to the usefulness of people in anti-administration cooling in extremely hot summer.But, with regard to present fan control, all be to adopt manual stepping control or time opening control, like this, use just very inconvenient, particularly have a rest in summer, in bed as people, because difference variation is big, driving fan and be afraid of to catch a cold, not blow in that To Be Protected from Heat again for fan, so people press for a kind of fan swicth that can regulate air quantity of fan according to environment temperature automatically.

The purpose of this utility model is exactly that a kind of electric fan switch that can regulate fan air flow according to environment temperature automatically will be provided.

To achieve these goals, the utility model has adopted following technical scheme: adopt the controllable silicon of connecting with the electrical appliance motor to cut the speed governing of ripple regulating circuit, circuit arrangement is installed on circuit board (5) in the governor housing of being made up of clamshell (1), base plate (2) and turn-knob (3); Controllable silicon is cut the ripple regulating circuit and is formed by connecting by diode D1, D2, D3, D4, resistance R 1, R2, R3, R4, R5, R6, R7, R8, capacitor C 1, controllable silicon G1, transistor G2, triode G3 and potentiometer W; D1, D2, D3, D4 connect into the bridge-type commutating circuit, its a, c point and fan motor M series connection power supply, its d point links to each other with controllable silicon G1 anode and resistance R 1 one ends, and its b point and controllable silicon G1 negative electrode and resistance R 3, capacitor C 1, resistance R 6, R8 one end (utmost point) link to each other; The R1 other end links to each other with resistance R 2, R4, R7 and potentiometer W1 one stiff end, sliding end; Resistance R 2 another termination transistor G2 one anode, another anode of G2 connects the controllable silicon G1 trigger electrode and resistance R 3 other ends, and the G2 base stage connects resistance R 5, capacitor C 1 other end and the triode G3 collector that is connected with resistance R 4 other ends, another stiff end of potentiometer W1; Triode G3 base stage connecting resistance R7, the R8 other end, the G3 emitter connecting resistance R6 other end.

Owing to adopted technique scheme, the utility model has ideally been realized its goal of the invention, has simple in structure, remarkable advantage such as cost is low, be quick on the draw, applied range, economize on electricity, be adapted to especially as the electric fan speed-regulating switch, the usefulness that also can be used for light modulation, temperature adjustment is present ideal a kind of electric switch.
