Description

Ceiling fan electronic timing speed regulator

The utility model relates to the control set for adjusting of electric fan in the mechanical engineering field, further is meant a kind of electronic timing speed regulator that ceiling fan uses that is particularly suitable for.

Existing ceiling fan generally carries out the stepping speed governing with the inductance type speed regulator, it only have single speed governing function and can not timing operation.If adopt mechanical timer, then not only timing is short and be difficult to harmonize, and device volume is big, also has mechanical noise.And,, and install inconvenient then because circuit complexity and cost height if adopt high-grade electronic timer.The ceiling fan electronic timing speed regulator that has also occurred non-top grade in the market, but its disadvantage, the one, the poor anti jamming capability that works long hours, thereby the accuracy of influence timing and speed governing; The 2nd, owing to adopt controllable silicon that ceiling fan is carried out stepless speed regulation, so that the serious proper functioning of disturbing extraneous other electrical equipment.

The purpose of this utility model provides a kind of electronic type timing governor that is particularly suitable for the cheapness that ceiling fan uses, and make its working stability reliable and not to external world electrical equipment produce electrical interference.

Solution of the present utility model can be referring to the electric functional-block diagram of Fig. 1.Its circuit part is made up of with display circuit (4) and gate turnoff thyristor circuit (5) stepping speed governing inductive circuit (1), D.C. regulated power supply (2), time base circuit (3), counting, divides retaining speed governing inductive circuit (1) to contain stepping speed governing inductance B and step switch K ₃, counting contains the manual count K switch with display circuit (4) ₁, gate turnoff thyristor circuit (5) contains enable switch K ₂The annexation of these circuit and signal flow are to being, stepping speed governing inductive circuit (1) is in series by former side and the gate turnoff thyristor circuit (5) of stepping speed governing inductance B, the auxiliary direction D.C. regulated power supply (2) of stepping speed governing inductance B provides AC-input voltage, D.C. regulated power supply (2) provides dc supply for time base circuit (3) and counting and display circuit (4), the timing pulse signal that time base circuit (3) equates a series of time spans is given counting and is counted with display circuit (4) and show, give gate turnoff thyristor circuit (5) by counting and display circuit (4) output control signal regularly again, with the Kai Heguan of control circuit (5).The utility model with foregoing circuit structure should be cascaded former side of stepping speed governing inductance B and the gate turnoff thyristor circuit (5) that is in series when mounted again with ceiling-fan motor winding M, in use by step switch K ₃Be connected on the alternating current 220V civil power, with step switch K ₃Place required gear, again with handling enable switch K once ₂, making gate turnoff thyristor circuit (5) conducting, ceiling-fan motor starts, and stepping speed governing inductance B gets electric, and D.C. regulated power supply (2) is to time base circuit (3) and timing and display circuit (4) power supply, by operating manual counter switch K ₁Ceiling fan is carried out timing working time to be preset, circuit (4) is exported timing controling signal within the predetermined time and is kept gate turnoff thyristor circuit (5) conducting, after regularly finishing, the no timing controling signal of circuit (4) flows to circuit (5), and circuit (5) turn-offs, the ceiling-fan motor stall, inductance B dead electricity, D.C. regulated power supply (2) quits work, so when the ceiling fan stall, not power consumption of entire circuit.

This novel electron timing governor carries out speed governing and the control of stepping regularly to the operation of ceiling fan, and timing is long, and does not have operate miss.The power supply of time circuit obtains from the speed governing inductance, and power circuit is provided with the voltage stabilizing adjustment, and this has just guaranteed the reliability and the antijamming capability of integrated circuit work, the precision of base when also having guaranteed.Its circuit structure is comparatively simple, and used components and parts are few, low cost of manufacture.Adopt the adjustment of inductance rotating speed and controllable silicon only plays on-off action, can as the thyristor speed control circuit like that to external world the work of electrical equipment produce interference.Installation and power supply mode and traditional speed regulator are just the same, and the integrated circuit assembling does not have the debugging element, adapt to and produce in enormous quantities.
