The utility model comprises a thalposis switching amplifier (1), a controller (2), an automatic switch (3), a rectifier voltage regulator (4) and a power switch K. The thalposis switching amplifier (1) transforms and magnifies electric signal of the induction of variable air temperature by thermosensitive elements. The controller drives a fan to rotate and regulates the variation of rotation speed. Compared with a stage adjuster of the existing electric fan, the utility model can automatically determine the critical temperature of the starting and operating fan according to people's requirements and can automatically adjust the rotation speed of the fan and the magnitude of air volume following the temperature change.
Description
The utility model discloses a kind of electric fan temperature control speed changer of regulating the rotation speed of the fan variation by variations in temperature automatically.
The rotational speed regulation of electric fan normally adopts the speed regulator speed governing, is to utilize choking coil directly to control the rotating speed that voltage is just regulated fan electromotor; The operating time of electric fan also can utilize machinery or electronic timer to carry out timing controlled except that manual control.Speed regulator and timer all are that speed regulator has static stall, is step speed change by operation manually, along with the rising or the decline of temperature, then want the class of frequent conversion speed regulator, could satisfy different needs; Timer has the set time restriction, and timing arrives, and fan is stall voluntarily, and people then must retime if need continue to get cold.The speed governing and the timing problems of electric fan existence have at present been brought many inconvenience to people apparently.
The purpose of this utility model is exactly for overcoming the problem that electric fan speed governing and timing aspect exist, a kind of electric fan temperature control speed changer that varies with temperature automatic adjusting fan speed change being provided.
The purpose of this utility model is achieved in that utilizes the induction of temperature-sensitive element to temperature Change, causes change in resistance, voltage changes, and forms temperature sense switching amplifier, converts the temperature sense to the signal of telecommunication, through amplifying, rotate and regulate rotation speed change again by the controller drives fan electromotor.
