Embodiment
Referring to figs. 1 through Fig. 6, the utility model frequency conversion fan embodiment is described further.
A kind of frequency conversion fan, comprise fan main body 1, described fan main body 1 is provided with controller 10, described controller 10 comprises frequency conversion module 2, alarm module 5, control module 4, sensor assembly 6, described control module 4 is connected with frequency conversion module 2, exports control signal to frequency conversion module 2 for long-range reception command signal; Described frequency conversion module 2 is connected with fan main body 1, for accepting control signal and the variable Ac fan main body 1 of output frequency; Described sensor assembly 6 is connected with control module 4, for collecting temperature, moisture signal, and exports to control module 4; Described alarm module 5 is connected with control module 4, in order to output alarm signal.The operation of blower fan is controlled by controller 10, control fan operation, use frequency conversion module 2 in the controlling simultaneously, saving power, improve Safety performance by alarm module 5, by sensor, enviromental parameter is inputed to control module 4, control module 4 can long-range reception command signal, facilitate people's distant control, efficiently solve the technical problem that blower fan in background controls inconvenience in utilization process.
As shown in Figure 6, described control module 4 comprises remote control unit 42, processor 41, described remote control unit 42 is in order to long-range transmission and receive command signal, remote control unit 42 adopts IR remote controller and infrared remote receiver, processor 41 is single-chip microcomputer, and the model of single-chip microcomputer can be the series such as STC89C51 or DSP2812, and described processor 41 receives remote control unit 42 signal and exports control signal, the control signal exported is PWM ripple, can control turning on and off of transistor.
As shown in Figure 5, frequency conversion module 2 is connected with input power 3, in order to change the Ac providing fan main body 1, frequency conversion module 2 comprises hands over straight conversion 21, power digital circuit 23, orthogonal circuit 22, and power supply is arranged by diode bridge, convert Ac to direct current, by capacitance energy storage, then carry out bridge type inverse by controlled transistor, while output AC electricity, frequency also there occurs transformation, frequency conversion module 2 exports and connects fan main body 1, makes blower fan be able to VFC.When by fan operation, dynamic braking effectively can suppress the pumping voltage produced in braking process, and its structure is simple, it is convenient to control, most of medium and small RHVC all adopts this mode of braking, only need reasonably select parameter and configure, all can reach desirable braking effect.
As shown in Figure 1, 2, fan main body 1 rear end is provided with protective housing 7, and described blower fan front end is provided with guide shell 9, and described guide shell 9 outlet is provided with spraying circle 8, protective housing 7 can prevent foreign matter to be involved in blower fan, also can prevent child from stretching in blower fan by hand, improve the Security of blower fan, and guide shell 9 can lead to wind-force, spraying circle 8 is detachably connected on exhaust outlet, can with atomizer with the use of, very convenient, eliminate carry spraying circle 8 trouble.
As shown in Figure 6, described alarm signal comprises heat alarm, humidity alarm signal, temperature signal and moisture signal are inputed to single-chip microcomputer by temperature transducer and humidity transducer, meanwhile, single-chip microcomputer output alarm signal, controls frequency conversion module 2 and quits work, alarm module 5 adopts passive buzzer, the square wave being exported certain frequency by single-chip microcomputer sends different alarm signal sound, knows that temperature or humidity are reported to the police, can pull out power supply after so just can hearing sound.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
