Abstract
The utility model discloses a speed regulator for ceiling fan, in particular to built-in speed regulator for ceiling fans using capacitances as speed regulation components. The utility model carries out pressure regulation and speed regulation control to electric fans utilizing a principle that capacitances present impedances in alternating current to generate decompression and adopts a speed regulation switch which can adapts the work characteristics of capacitance connection in parallel. Because of the characteristic of the low work power consumption of capacitances in alternating current circuits, the built-in structure of the speed regulator for ceiling fans is achieved. The utility model is composed of a standard sized built-in electrical appliance panel, a speed regulation switch and a combined capacitor. The utility model has the advantage of low cost and in particular adopts capacitances as speed regulation components to solve a technical problem that the speed regulator for ceiling fans realizes enclosed built-in structure.
Description
The utility model is about hanging fan governor.Particularly a kind of concealed hanging fan governor that adopts electric capacity to make the speed governing element.
The control apparatus of concealed installation structure is by panel, electric elements, compositions such as line box, and its good looking appearance again can combination in any, is widely used in the office space, hotel, resident family.Traditional hanging fan governor adopts band reactor unshakable in one's determination to make the speed governing element, utilize the reactance decompression principle that electric fan is carried out speed regulating control, exist power consumption big, the shortcoming that working temperature is high, be difficult to realize the concealed structure of sealing, make it when electrical equipment is installed, having speed regulator only is that salient mounting structure and other concealed installation electrical equipment are extremely inharmonious.If select a kind of low-power consumption, the alternative reactor formation of the electric elements that working temperature is low concealed installation structure is carried out speed regulating control to ceiling fan its Practical significance.
The purpose of this utility model is the shortcoming at the reactance speed regulator, has proposed to adopt electric capacity to make the concealed structure that the speed governing element is realized the ceiling fan speed governing.
The scheme that solves is to use a group capacitor, and the quantity of capacitor is decided by the required speed governing retaining number of electric fan.And the control switch that configuration and electric capacity speed governing work characteristics adapt is formed concealed hanging fan governor.
In alternating current circuit, electric capacity can be considered an impedance and makes voltage drop element usefulness.See accompanying drawing 1 if make the circuit of speed governing element with electric capacity.M is a ceiling fan among the figure, keeps off speed governing with five of ceiling fan and requires to adapt, and capacitance group C1-C4 forms.K is five retaining speed-regulating switchs, and the position of the switch among the figure is in open position.When K changed in the direction of the clock step by step, the operating state of circuit saw the following form:
| The position of the switch | The electric capacity operating state | Fan speed | |
| 0 | Circuit disconnects | Stop | |
| 1 | The whole short circuits of electric capacity | At a |
|
| 2 | C1, C2, C3, C4 also connect work | Middling speed 1 | |
| 3 | C1, C2, C3 also connect | Middling speed | 2 |
| 4 | C1, C2 also connect work | Middling speed 3 | |
| 5 | C1 work | Low speed |
Foregoing circuit has characteristics: electric capacity by speed-regulating switch one by one and connect, and the electric capacity that connects is many more, capacitive reactance is more little, fan speed is high more, when electric capacity during by whole short circuits (position of the switch 1), fan speed is the highest.Adopt and connect the total capacity that mode can reduce the electric capacity that puts into operation.
Group capacitor among Fig. 1 can be placed in the shell, forms a combined capacitor, and inner electric capacity wiring is undertaken by circuit requirement, has adopted this structure to significantly reduce the volume of capacitance group, and simplifying assembling and cost can compare favourably with reactor.
Accompanying drawing 2 is embodiment of the present utility model, and it has described the formation of concealed hanging electric fan electric capacity speed regulator.Wherein 1 is the concealed installation appliance panel of conformance with standard size, and there is the indicating graduation of speed governing retaining in the front.The 2nd, by the speed-regulating switch of Fig. 1 structure.The 3rd, the speed-regulating switch handle is open position among the figure.The 4th, combined capacitor.
The utlity model has following characteristics: 1, adopt the electric capacity speed governing, 1-2 the order of magnitude hang down in loss ratio reactance speed governing, no power waste almost during operation, and working temperature is low, and the efficient of raising system in view of above characteristics, has constituted concealed structure.2, speed governing electric capacity is a combined capacitor, has volume little, the advantage that cost is low.3, electric capacity has significantly reduced the electric capacity total capacity with one by one and connect the mode speed governing.4, adopted suitable electric capacity and connect the control switch of work characteristics.
Claims (2)
1, a kind of hanging fan governor, particularly a kind of concealed ceiling fan electric capacity speed regulator is characterized in that using a combined capacitor: speed-regulating switch is formed, and is installed on the general standard-sized concealed panel.
2, according to the hanging fan governor of claim 1, it is characterized in that speed-regulating switch can be by electric capacity speed governing characteristics one by one and connect work.
