Main element symbol description
Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Referring to Fig. 1, a kind of retation speed of electric fan controls system 10 and is applied in an electric fan, is automatically adjusted the rotating speed of electric fan for the ambient temperature residing for electric fan. This retation speed of electric fan controls system 10 and includes fan blade 12, electromotor 14, storage element 16, switch element 18, temperature induction unit 20 and control unit 22.
Storage element 16 is used for storing a temperature rotation speed relation table. Temperature rotation speed relation table is used for the relation showing between temperature and the rotating speed of environment. Temperature range in temperature tachoscope is 28 DEG C-36 DEG C, rotating speed range for 500-1500 rev/min, and the corresponding high rotating speed of high-temperature.
Switch element 18 is for controlling being turned on and off of electric fan. Temperature induction unit 20 is for the temperature of sensing environment residing for electric fan when electric fan is in opening. This temperature induction unit 20 can be a circuit including critesistor. The resistance of critesistor can raise along with the rising of temperature, and when this circuit change in resistance at critesistor, the voltage of output also changes, so that this circuit exports different voltage when different temperatures. This temperature induction unit 20 draws the temperature of the environment of correspondence according to the different voltage of output. In the present embodiment, temperature induction unit 20 is according to a Preset Time, such as two hours, and the temperature of gap periods ground sensing environment residing for electric fan. In another embodiment, temperature induction unit 20 senses the temperature of the environment residing for electric fan in real time.
Control unit 22 controls electromotor 14 for the temperature according to the environment sensed and temperature rotation speed relation table and rotates according to the rotating speed corresponding with the temperature of the environment sensed. Electromotor 14 is used for driving fan blade 12 to rotate.
In the present embodiment, also including a preset threshold temperature in this temperature tachoscope, such as 25 DEG C, control unit 22 is additionally operable to when the temperature of environment is lower than this preset threshold temperature, controls switch and closes electric fan. So, when the temperature of the environment that temperature sensing unit again senses after electric fan rotates described Preset Time with a rotational speed is less than 25 DEG C, control switch cuts out fan by control unit 22. Because when environment is less than 25 DEG C, will no longer be required to blower fan, it is possible to prevent from being opened by fan causing that the user of blower fan catches a cold always.
This retation speed of electric fan controls system 10 and also includes display unit 24. This display unit 24 is for showing the temperature of the environment sensed. So, user can learn the temperature of environment by display unit 24.
Referring to Fig. 2, be the flow chart of a retation speed of electric fan control method, this retation speed of electric fan control method is applied to control in an electric fan rotating speed of electric fan, and the step that this retation speed of electric fan control method includes is as described below.
Temperature induction unit 20 senses the temperature (step S102) of the environment residing for electric fan when electric fan is in opening. In the present embodiment, temperature induction unit 20 is according to a Preset Time, such as two hours, and the temperature of gap periods ground sensing environment residing for electric fan. In another embodiment, temperature induction unit 20 senses the temperature of the environment residing for electric fan in real time.
Control unit 22 shows that according to the temperature and of the environment sensed the electromotor 14 of the temperature rotation speed relation table control electric fan of relation between temperature and the rotating speed of environment carries out rotating (step S104) according to the rotating speed corresponding with the temperature of the environment sensed. Wherein, the temperature range in temperature tachoscope is 28 DEG C-36 DEG C, rotating speed range for 500-1500 rev/min, and the corresponding high rotating speed of high-temperature.
Electromotor 14 drives fan blade 12 to rotate (step S106).
In one embodiment, step S108 and step S110 is also included.
The temperature (step S108) of the environment that display unit 24 display senses.
Control unit 22, when the temperature of environment is lower than a preset threshold temperature, closes electric fan. This preset threshold temperature is 25 DEG C (step S110).
Above-mentioned retation speed of electric fan controls the rotating speed of the temperature automatic adjustment electric fan of system 10 and control method environment residing for electric fan, it is not necessary to be used for doing it yourself to be adjusted, more intelligent.
Those skilled in the art will be appreciated that, embodiment above is intended merely to the explanation present invention, and it is not used as limitation of the invention, as long as within the spirit of the present invention, above example is made suitably change and change all drops within scope disclosed in this invention.
