DETAIlED DESCRIPTION OF THE INVENTION: As already known to all, the cold air current drops down and the hot air current goes up, and there is a temperature between a place further to the air conditionir.g equipment source ( such as an air cooler or heater ) and anther place closer to the same air conditioning equipment source, to improve this defect, in recent years the people often use a ceiling fan to stir the air flow in an air conditiored room. thus achieving the object of an even air conditioned room temperature distribution, during a ceiling fan blows rug downward is used to stir the cool air flow, and during winter, z ceiling fan blowing upward is used to blow tbe lusted air flow up, thereby achieving the object oi an even temperature distribution in a room, but due to the sharp differences in the construction spaces, it is still Impossible to make the air flow in various corners evenly flow and a similar situation exists the applicatory state of the air suction/exhaust fans, please refer to Figs. A,B C C and D. The design of the invention is that a fan is added with a cyclic positive and reverse switch whichis operated to make the fan conduct the cyclic positive andwreverse revolutions, thereby achieving the even air flow-stirring effects Since most motors of the fans are of the singlephase type, now several examples of the single-phase motors will be mainly cited. There are many circuit elements and circuits for the cyclic positive and reverse switching of the fan motors to include a great variety of analogic or digital elements such as the generator or electronic elements or microprocessors added with the timing softwares, or further the mechanical reduction structure is used to move the double stable state switch to conduct the cyclic positive and reverse revolutions, so the execution means available are too numerous to mention here. Since the object of the invention is a means that the cyclic positive and reverse switch is used to change-over the fan for the cyclic positive and reverse revolutions, in the follwing various exan:}les, only several ow the. are cited to prove the invention feasible, as to various analogic or digital measures of z wide variety of the generator or electronic or mechanical or computor software @iming will not be elaborated one by one here, because they belong to the conventional negative and only; ;groted by the invention, which shall not be detrimental incorporation of them into the definition of the present invention. Fig. 1 is a view of the block diagram of the invention, in the drawing 101 is the positive and reverse switch element constituted by a solid state semi-conductor element or al relay operation and control of the cyclic circuit, thereby making the fa/ motor 103 conduct the cyclic positive and reverse revolutions; 102 isa cyclic circuit constituted by an analogic or digital generator or electromic circuit or microprocessors to generate the cyclic operational signals for operating and controlling the switch elements 101, its cyclic signals include the seguence changes that often a positive revolution direction persists a set time, then a reverse revolution instruction persists a period of time, and them a positive revolution instruction is generated, or a time interval of the current interruption exists between two oppositive instructions; 103 is constituted by the single phase motor including AC or DC motor for the positive and reverse revolutionarb drive. In other words, the invention can be cowposeu of a cyclic positive or reverse air flow-stirring far hiving a positive and reverse revolutionary fan, and the Positive and reverse revolutions can change the blade sets that fan and r..e in tile sare direction, a hang device and a control device, in addition to that the selection switch is used to select tbe continued positive or reverse revolution. its main feature is to set the continued cyclic positive and reverse revolutions; the features of its various drive cycles are described as follows: 1) The above-said operating cycles include the directly continued positive and reverse reVolutions to change the air flow directions in sequence. EMI6.1 2) The above-said operating cycles include a mild EMI6.2 startand mild stop continuity to make the motor load reduced. 3) The above-said operating cycles include a machine stop time interval between the positive and reverse revolutions to make the air flows naturally mixed and also to make the motor load reduced. As in the example shown in Fig. 1-1, the time sequence clock 101 is to generate the drive cyclic instruction, thereby making the relay RY 101 conduct the cyclic or and off actions, after the coil of the direction change-over relay RY 102 is connected in series with the NO contact point of the relay RY 101 and with the NC D point of the relay RY 103 and then is connected to the coil of the pover aupply auxiliary relay RY 103 and the NC contact point of RY 102 and the contact point of RY 101, the coil of the RY 102 is also connected in parallel with the power supply the power supply of the motor and the constantly open and tired contact point of the time TR 101 connected to the tor in series will close after the timer TR 101 has received the electric power for some time; its start coil is subjected to the operation and double throw contact point of RY 102 for the direction change-over actions, and alter TR l}. l is connected in series with the constantly closed contact point of RY 102 and RY 103 in a series state, TR 101 is also connected to the power supply when and after the power supply delivers the electric current, the clock 101 will in seqence generate the drive signals to make the RY 101 conduct the cyclic ON and OFF actions, while direction relays:RYl102 and 103 operated and controlled by the RY 101 also alternately act; since the O' and OFF actions of the RY 102 make the start winding of the motor appear in an corresponding positive or reverse revolutionary winding; since the TR 101 is a subjected to the operation and control of the contact point of the RY 102 and the RY 103, this make them all reset during the alternate changeover of the direction, which, in turn, makes the drive motors operated and controlled by their delayed contact point have a machine stop time interval after the direction changeover action. 4) The above-said operating cycle includes that its operations have the programable speed changes and both of the positive and reverse cycles to meat various requirements The following Figs. 2-1 & 2-4 are the examples of various mutually compatible brief and important measures and functions constituting the invention. Fig. 2-1 shows that a control unit generates a cyclic continued signal to drive a direction changeover relay RY 201 to changeover the moto in a direction changeover action, this is the simplest form to make the motor the positive and reverse cyclic drive in a continued drive as shown in Fig. 2-1 A, and the Sl; 201 is operated and select for the continued positive revelution or continued reverse revolution. Fig. 2-2 shows that a control unit operates and controls a direction changeover relsy SLY 101 ud the TR1AC 201 connected in series with the motor power supply uses the LED 201 and the CDS 201 coupled with the LED 201 to conduct the switch operating actions, thereby generating the continued wild changeover as shown in Fig. 2-2 A, or the intermittent positive and reverse revolutions as shows in Fig. 2-2 B, or the positive or reverse electric power-saving uni-direction intermittent operations as shown in Fig. 2-2 C, and also to still maintain the conventional continued positive revolution or continued reverse revolution, further the variable resistor VR 201 conducts the relative control over the TRAC 201 to make the fan motor change its speed, but as this kind of circuits are often seem, no repetition on them is needed here. As shown in Fig. 2-3, the operation and control of the switch SV; 20l'are put into the control device to operate and control the direction changeover relay 201 and the relay RY 202 in series with the motor to generate the continued positive or reverse revolution as shown in Fig. 2-3 A, or the operations of the continued and intermittent operational selection switch SW 202 conduct the intermittent positive and reverse operations as shown in Fig. 2-3 B, or the unit-direction electric power-saving intermittent drive as shown in Fig. 2-3 C, and also maintains the original functions of continued positive revolution or continued reverse revolution, in the drawing, when the 5W 201 is tangential to the point a the motor conducts the continued positive revolutions, when the 5? 201 is tangential to the point b, the motor SW 201 is tangential to the point C, the motor concucts the continuted reverse revolutions, SW 202 is an intermittent and continued functional selction switch to select the above-said functions as the continued or intermittent functions As shown in Fig. 2-4, a view illustrates the brief circuit of the example that the control device operates and controls the directions to sets of the TREAC 202 and TRIAC 203 conduct the direction selection and switching and phase control; the drawing, the setting of the SW 201 makes the control unit respectively trigger the TRIAN 202 and the TRIAC 203 to serve as the switching functions, thereby making the motor conduct the positive revolutionary or reverse revolutionary drive, or the cyclic positive and reverse revolutions as shown in Fig. 2-4 A, and as shown in Fig. 2-4B the SW 202 makes the selection of continuted or intermittent operations, or as shown in Fig 2-4 C, makes the motor conduct the uni-direction intermittent electric poxer-saving drive, besides, the VR 201 is for the operation of thc phase-control speed changes. Fig. 3 is another example of the block diagram shown in Fig 1. in Fig 3, 5W 301 is a master switch, in the drawing, the common connection end of the two windings W301 and W302 of the single-phase sysmmetric winding-type capacitance motor is connected to the switch SW 301, and the other end of the windings W 301 and W 302 are connected in parallel to the two ends of the caracter @ 310 and then respectively to the @ and sad reverie revolutions. (2) When the common contact point of the selection switch is electrically communicative to the point b, now the relay RY 301 will normally not accept any electric current so the motor normally is driven toward the positive revolution. (3) When the common contact point of the selectiop switch S 302 is electrically communicative to the point C, the RY 301 normally accepts the electric current for actions, so the motor normally is driven toward another direction. In the drawing, the voltage step-down resistor R301 can accept the votage changes of the transformer TR 310 due to the regulation on the speed cithout affecting the speific DC voltage input. Fig. 4 is an example of the block diaram as shown in Fig. l. In Fig. 4, the thermal cyclic relay HRY 401 is a drive element to constitute the functions of the positive and reverse revolutionary cycles to operate the fan motor, the motor shown in Fig. 4 has a travel coil W 401 and a speed variation coil W 403 wound co-axially with the coil W 401; the speed variation coil U 403 is split and drawn with proper draw chucks which is connected to the distribution contact points of various groups of the speed control switch SW 301: one of its drav. chucks corunicates with one of the common contact points of the RY 402 the RY 402 is a diode double throw relay, and its another common co-tact point connuricates with one enci of tie start capacitor C410; after the two sets of N0 contact points of te RY 402 are mutually connected is a cross way Ud also connected to the start coil W 402; the other end of the start capacitor C 410 is connected to the other end of the travel winding w 401 and then to one end of the power supply; the contact point X of one set of the thermal relay HRY 401 is connected in series ith its own thermal resistor; one end of the heating resistor of the thermal relay HRY 401 is connected to the distribution contact point of the speed switch 5W 401 end the other end of the power supply ; the selection switch 402 has three distribution contact points a, S and C, of which the contact point a is connected to the contact point pin Y of the thermal switch HRY 401 the another contact point b is not connected to any thing, the contact point C is connected to the contact point X of the thermal switch HRY 401, and the common contact point b is connected to the coil of the relay RY 402 to making this circuit conduct the following operations: 1. When the selection switch is placed at the point A of the SW 402, the fan makers the automatic positive and reverse cyclic cycling, the process is that when the SW 1 is at ON, since the HRY 401 has hot reached the action temperature, its normal temperature close contact points X and Y rakes the coil of the RE' 402 accept the electric current which in turn makes the contact point of the R 402 acted; now the motor runs in one direction when the heating resistor of the HRY 401 continuously heats to reach the action point of the HE 401, the ccr.tact point X ad Y trip off to make the relay RY 402 irterrupted in the circuit which, in turn, makes its contact point a'lao tripped oti, which further .akars the motor ran in z reverse revolutionary state, until the HRY 402 dissipates, i,ts heat until it restores its original temperature, now its contact points close and the motor runs again in a positive revolution, so this reciprocates all the way. 2. When the selection switch SW 402 is placed at the point b. now the relay RY 402 will permanently not be electrically communicated, thus making the motor constantly run in the reverse revolution. 3. V;hen the selection switch SW 402 is placed at the point C, now the relay continuously accepts the electric action and the motor continuously conducts the positive revolutionary Fig 5. is another example of the block diagram shown in Fig. 1 and its main compoments are described as follows: : ------ -- a single phase motor having a travel winding and a start winding and a split phase capacitor, of which the point W is a common point, the point U is a positive revolutionary input point, the NC contact point of serial relay RY 503 and the ND contact point of relay RY 502 are then connected to the speed change switch, the point V is the input point of the reserve revolution, the NC contact point the serial relay RY 502 and the NO contact point of the RY 503 are then connected t the speed change switch SW 502; ------ a diode CR 506 and the capacitor C504 constitute a straight wire; ; ------ the two ends of the temperature switch TS 501 are respectively connected to the points a and b of the switch SW 501, and z resistor R 501 is connected to the Positive eletrode of the power supply and the point c of the 8W 501; ------ the common point of the single kinfe distrution switch SW 501 is connected to the coil of the RY 501 and then to the negative end of the power supply, and a diode CR 501 of a fly wheel is connected in series to the end of the coil of the relay RY 501; ------ the common contact point of the diode RY 501 leads to the positive end, its NC contact point is connected in series in a reverse direction vir a diode CR 502 and the coil of the relay RY 502 to lead to the negative end; ; a resistor R 502 and a capacitor C 502 form a charging delay circuit which is connected in series with the two ends of the coil of the relay RY 502 is connected in series in a reverse direction to the two ends of the resestor R 502 and then forms, with the C 502, the discharge circuit limited b the invarialbe resistor R 502; ------ the NO contact point of the relay RY 501 is connected in series to a diode CR 503 and the coil of the relay RY 503 to lead to the negative end; a resistor R 503 and a capacitor C 503 form a charge delay circuit which is connected in series to the discharge circuit limited by an invariable resistor R 503. The actions of the above-said circuits include: 1, When the switch 5". 501 is placed at the point a, ard while the temperature switch TS 501 is heated by the R 501 but has not reached the actior point, the RY 501 accepts the electric action, the positive power supply goes through the NO contact point of the RY 501 and also via CR 503 and RY 502 to make the coil of the RY 503 accept the electric action, to enable tbe rotor running in z remorse revolution, now the electric current goes through the R 503 to charge the C 503; when the temperature switch TS 501 is;.heated;to act, the relay RY 501 cuts off the electric current supply, its NC contact point accepts the electric current, the electric energy goes through the CR 502 and also via the coil of the RY 502 to the negative end, no the electric current goes through the R 502 and chargessthe C 502, the RY 502 accepts the electric current to act, the electric energy for the motor originally goes through the RY 503 is cut off, but now the capacitor C 503 makes the RY 503 accept the electric power via the CR 505 to make the R 503 still accept the electric current to maintain a period of time, which, in turn, makes the electric energy not go to the positive evolutionary wire end U via the contact point of the RY 502 until the capacitor C 503 discharges to the effect that RY 503 is released; when and after the TS 501 is cooled off and restores to its original position, the relay RY 501 is electrically conductive and its NO contact point accepts the electric carrent the electric energy goes through the CR 503 and also via the coil of the relay RY 503 to the negative end, no the electric current goes through the R 503 and charges the R 503, the RY 503 also accepts the electric current to act, the electric energy originally flowing through the RY 502 to the motor is cut off, holiever the capacitor C 502 makes the RY 502 still accept the electric current via the via the CR 504 to still maintain a period of tire, thus making the electric energy nct flc' to the reverse revolutionary wire end V via the contact point of the RY 503, until tbe capacitor C 50 discharges to the effect that the RY 502 is released, so this reciprocates, thereby forming the positive and reverse cyclic cyclings with the electric stop interval therebetween. 2. When the switch Sw 501 is changed to the point b, the RY 501 constantly does not accept the electric current, now the point U of the motor constantly accepts the electric current, and the motor is in the continuous positive revolution. 3. When the switch 5W 501 is changed to the point C, the RY 501 constantly accepts the electric current, now the point V of the motor constantly accepts the electric current, and the motor is the continuous reverse revolution.

In other word, aften the drive rotor 601 starts t6 run, the reduction transm.ission elemEnt coupled to its motor shaft can be tbe fixed speed ratio of the trtnmlssion type of the gear belt frictional wheel or the adjustable speed ratio, its final output will drive two sets of the touch stops into motion to respectively poke the double stable state switch at the termination of each cycle of the positive and reverse revolutions to chang over the rotary direction of the motor to which, in turn, changes the direction of the air flou driven, the clamp space betueen the touch stops used by above-said poking switch can be fixed or adjustable to change the cycle accordingly. Summing all the above up, the design of te invention is to specially design the air flov-stirring fans such as the ceiling fans or ventilators into a cyclic positivE- and reverse revolutions, thereby enhancing the evenness of the temperature in E room and eliminating the dead angles at well as raising the flow circulation and exchange effects of the air fans particularly the novelty of its concept is apparent and the means are natured and practicalle, so un doubtedly this is a dosage with a high practicull@ity
