Abstract
The utility model relates to a speed adjustment device used for the breeze ceiling fan, comprising a B-shaped iron core whose two side posts are respectively coiled with a coil L-[1] and a coil L-[2] in series connection and middle post is coiled with a coil L-[3] and a coil L-[4] and also connected with an electromagnetic transformer of frequency division formed by a capacitor, a transfer switch and a power supply socket. The electromagnetic transformer of frequency divides the commercial electricity whose frequency is 50Hz into the ac electric supply whose frequency is 25Hz to convey the electricity to the breeze ceiling fan to enable the rotation speed of the breeze ceiling fan to reduced into one half of the original rotation speed with air quantity reduction. The breeze ceiling fan is directly connected with the commercial electricity by the transfer switch to recover the original rotation speed to change one kind of fixed rotation speed of the breeze ceiling fan of permanent magnetic synchronous motor type into two kinds.
Description
The utility model belongs to electrical appliance, is a kind of speed controller for breeze ceiling fan.
At present, a kind of breeze ceiling fan is arranged on the market, it has characteristics such as small and exquisite, energy-conservation, that wind-force is soft, be subjected to very much people's welcome, but because this breeze ceiling fan adopts is that permagnetic synchronous motor is used as power, thereby the qualification that is subjected to mains frequency has only a fixing rotating speed, and does not have speed-regulating function, this uses when temperature is higher for the hot summer, and air quantity still can.But when temperature is low slightly, especially use under the situation early summer or late summer etc., feel that then air quantity is big, air-cooled, and as feeling too hot and unhappy.Therefore, this have only a kind of breeze ceiling fan of rotating speed to bring many inconvenience to people, also influenced its utilization rate.For meeting the needs of, people adopt the method for lifting hanging height to adjust air quantity more, and this way is very inconvenient, and is also dangerous.Also have in addition with the angle that changes fans and adjust air quantity, though some effects are arranged, it has reduced efficiency of motor, and is unfavorable energy-conservation and adjust and use also trouble.In addition, adopt the frequency-variable electronic mode to make speed regulator in addition, but the circuit complexity, cost is big, and high order harmonic component is former thereby undesirable to other household electrical appliance serious interference etc. in the square wave power of output.
The purpose of this utility model is for overcoming existing breeze ceiling fan because of having only a kind of rotating speed, adopt not only complexity but also bother of above-mentioned way, effect is undesirable to use weak point such as make troubles, and provide a kind of electromagnetism frequency division wind hanging fan governor that declines, it can make breeze ceiling fan become two kinds by a kind of rotating speed, has improved the use selectivity, and it is little to have a volume, the efficient height, dependable performance and other household electrical appliance are not produced characteristics such as interference.
The utility model is to realize like this, utilization divides frequency power transformer with the mains supply of frequency for 50Hz through improved electromagnetism, and frequency division becomes the 25Hz power supply, and is delivered to the breeze ceiling fan motor through change over switch and socket, make its rotating speed be reduced to half of former rotating speed, air quantity reduces.When air requirement is big, civil power directly can be connected with breeze ceiling fan by change over switch, promptly return to former rotating speed, thereby realized making breeze ceiling fan to have two kinds of rotating speed adjustable, made things convenient for use.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in detail.
Fig. 1. be that schematic diagram cuts open in three-dimensional office of the present utility model.
Fig. 2. be basic circuit diagram of the present utility model.
Fig. 3. be the structural representation that electromagnetism divides frequency power transformer in the utility model.
With reference to accompanying drawing, the both ends of the surface of one plastic casing [ 1 ] have heat radiation grid grooves [ 2 ], front plate is equipped with indicator light [ 3 ], change over switch [ 4 ] and supply socket [ 5 ], [ 1 ] inside is equipped with an electromagnetism and is divided frequency power transformer, it is made up of " day " font iron core B, elementary winding, secondary winding, diode D, potentiometer W and capacitor C, and elementary winding is by coil L
1With coil L
2Differential concatenation constitutes, and is wound on respectively on the two side columns of " day " font iron core B, and the enamelled wire coiling of two coils employing same specification line warp and institute are around equal turn numbers, and a rectifier diode D is serially connected in the circuit of elementary winding.Secondary winding is by coil L
3And L
4Series connection constitutes, and is wound on the center pillar of " day " font iron core B coil L
4Institute is coil L around the number of turn
35~15%, the one potentiometer W and the coil L of the number of turn
4Parallel connection, one of a capacitor C is connected on the central contact of potentiometer W, and the other end is connected to coil L
3Far-end on, coil L
3Two outputs be connected to a change over switch [ 4 ], [ 4 ] are two retainings, three cutter interlocks, wherein two cuttves are as the usefulness of power source conversion, front end respectively with mains supply and coil L
3Two ends join, and the rear end is connected to a supply socket [ 5 ], and another cutter is as switch, with its control electromagnetism frequency division transformer circuit.Input at civil power also is serially connected with a K switch and is parallel with current-limiting resistance R and the indicator light [ 3 ] of LED composition.
Used iron core B preferably adopts small power transformer with " GE(B) " type or " ED " type silicon sheet core, builds up " day " font structure.
Capacitor C can adopt a polarity free capacitor or be made of the reverse serial connection of two electrochemical capacitors, and its capacity is 1~10 way, and is withstand voltage greater than 250V.
The course of work of the utility model speed regulator is: breeze ceiling fan M is inserted on the socket [ 5 ], this speed regulator attaching plug [ 6 ] inserts on the civil power, connects K switch, and indicator light [ 3 ] is luminous, as when selecting to keep off soon, making frequency by change over switch [ 4 ] is that the civil power of 50Hz directly links to each other with M, and promptly with former rotary speed working, air quantity is big for breeze ceiling fan, this moment, electromagnetism divided the circuit of frequency power transformer to be cut off, to reduce power consumption, when selecting to keep off slowly, by change over switch [ 4 ] with coil L
3Two outputs be connected with M, and connect the circuit that electromagnetism divides frequency power transformer simultaneously, so the 50Hz civil power is rectified into half-wave current continuously by primary, by means of the effect that discharges and recharges of capacitor C through diode D, make left and right sides two parts of iron core B alternately saturated, thereby at coil L
3On to induce frequency be that 25Hz, voltage are the AC power of 100~160V, make breeze ceiling fan to be lower than half rotary speed working of former rotating speed, air quantity reduces, can change the time constant that discharges and recharges of capacitor C by regulator potentiometer W, make the ac power frequency of output stabilize to 25Hz and waveform symmetry, electric current is steady.
The utlity model has simple in structure, reliable operation, processing and manufacturing is easy, small and exquisite, the advantage such as energy-conservation and easy to use, and because of output be to intend sine-wave power, so other household electrical appliance are not produced interference, can directly support the use with existing breeze ceiling fan finished product easily.
