Abstract
The invention discloses a stand electric fan, and belongs to the technical field of household appliances. The stand electric fan comprises a main motor M1, a speed controller, a timer and a safety switch; the main motor M1, the speed controller, the timer and the safety switch are in series connection; the two ends of a series-connection line are connected with a live wire end L and a null line end N of a plug respectively; a ground wire of the main motor M1 and a ground wire E of the plug are grounded; a synchronous motor M2 is in parallel connection to the main motor M1. The stand electric fan is characterized in that the speed controller is a stepless speed controller; the input end of the stepless speed controller is A, and the output end of the stepless speed controller is B. The problem that the wind of the stand electric fan is too large, people are prone to having a cold is solved.
Description
Technical field
The present invention relates to household electrical appliance technical field, especially a kind of table fan of stepless speed regulation.
Background technique
Summer, people fell apart except the heat of human body by means of fan usually, present various electric fans on the market, generally all be provided with 1-4 gear, gear is once select, its rotation speed of the fan just immobilizes, air quantity and wind speed is caused to immobilize, when not being awfully hot weather, after people's nighttime sleep a period of time, the demand that human body brushes heat radiation by fan can reduce relatively, if still adopt the mode that above-mentioned conventional fan is brushed, even if fan is selected in minimum gear, room temperature reduction adds that human body progresses into physiology cooling when sleeping soundly state, easily cause the generation of the symptoms such as flu.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of table fan, and this table fan can solve the excessive problem easily causing people to catch a cold of table fan air quantity.
In order to solve the problem, the technical solution adopted in the present invention is: this table fan, include the mair motor M1, speed regulator, timer, the safety switch that are connected in series each other, the two ends of this series circuit are connected with zero line side N with the live wire end L of plug respectively, the ground wire of described mair motor M1 and the ground wire E of described plug are connected on ground, described mair motor M1 goes back a synchronous motor M 2 in parallel, described speed regulator is stepless speed adjusting gear, the input end of described stepless speed adjusting gear is A, and output terminal is B.
In above-mentioned table fan technological scheme, technological scheme can also be more specifically: described stepless speed adjusting gear includes the first line that potentiometer RP, the first resistance R1 and the first electric capacity C1 are composed in series; The second circuit that second electric capacity C2 and the second resistance R2 forms; Described first line, described second circuit and a bidirectional thyristor VS are connected in parallel in A, B two ends, circuit between described first resistance R1 and the first electric capacity C1 is connected with one end of a bidirectional trigger diode VD, the other end of described bidirectional trigger diode VD is held with the G of described bidirectional thyristor VS and is connected, described A end is connected with motor, and described B end is connected with timer.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, structure of the present invention is simple, easy to use, can regulate rotation speed of the fan as required, avoids human body to cause the illness of flu.
2, present invention saves electric energy and cost, extend the working life of motor.
Accompanying drawing explanation
Fig. 1 is electrical schematic diagram of the present invention.
Fig. 2 is the electrical schematic diagram of stepless speed adjusting gear 4 in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Table fan shown in Fig. 1, include the mair motor M1, stepless speed adjusting gear 4, timer 3, the safety switch 2 that are connected in series each other, the two ends of this series circuit are connected with zero line side N with the live wire end L of plug 1 respectively, the ground wire of mair motor M1 and the ground wire E of plug 1 are connected on ground, mair motor M1 go back a synchronous motor M 2 in parallel.Stepless speed adjusting gear includes the first line that potentiometer RP, the first resistance R1 and the first electric capacity C1 are composed in series; The second circuit that second electric capacity C2 and the second resistance R2 forms; First line, the second circuit and a bidirectional thyristor VS are connected in parallel in A, B two ends, circuit between the first resistance R1 and the first electric capacity C1 is connected with one end of a bidirectional trigger diode VD, the other end of bidirectional trigger diode VD is held with the G of bidirectional thyristor VS and is connected, the input end of stepless speed adjusting gear is A, output terminal is B, A end is connected with motor, and B end is connected with timer.
During work, switch on power owing to sealing in the regulating circuit be made up of elements such as bidirectional thyristor VS, bidirectional trigger diode VD, potentiometer RP, resistance R1, R2 and electric capacity C1, C2 in electric fan motor winding.In regulating circuit, resistance R1 charges to electric capacity C1, when the charging voltage on electric capacity C1 reaches the trigger voltage of bidirectional trigger diode VD, bidirectional trigger diode VD conducting, make bidirectional thyristor VS also triggering and conducting, so there is electric current to flow through motor winding, rotate the potentiometer RP in alignment circuit, by regulating its resistance value, the charging time constant of adjustable condenser C1, also just have adjusted the Trigger Angle size of bidirectional thyristor VS, the operating voltage at motor winding two ends is also changed thereupon, thus reaches the object of stepless voltage regulation speed governing and adjustment air quantity.
