Background technology
The widely used smoke exhaust ventilator of family all is to adopt common single-phase asynchronous motor as power motor at present, because the smoke exhaust ventilator load inertia is big, the single-phase asynchronous motor starting current is just very big, the 5-7 that may reach rated current doubly, at this moment the machine operation revolutional slip is big, cause reactive loss big, operating current is big, and the line loss that electrical network is caused also increases; Electric efficiency is than lower under the general torque type load behavior, and general efficient can not surpass 60%, and this just causes very big unnecessary waste of energy; In addition, consider that general household smoke exhaust ventilator does not have the speed governing gear available from the cost aspect, use inconvenience, when oil smoke is very little, still with oepration at full load, can bring very big operating noise,, need to increase machinery and structure fringe cost easily in order to reduce noise; The smoke exhaust ventilator that has gear to select on the market, operated by rotary motion has only the 2-3 shelves, gear is the winding decision of motor itself, want many one grade of one group of winding coils how, this not only increases motor volume and copper wire material, causes the waste of material, and use inconvenience, can only in fixing 2-3 shelves, select, can not accomplish the stepless speed regulation of certain range of speeds, reach the well balanced of lampblack-pumped effect and noise; Have, single-phase asynchronous motor adopts capacitor start again, and starting power is little, and electric capacity also is consumable accessory, and working life is not long, can not keep in repair after the loss, brings the waste of material.
The utility model content
Technical problem to be solved in the utility model provides a kind of under same effective power condition; than single-phase asynchronous motor littler volume is arranged; higher efficient and power factor; and can realize the continuous speed adjustment function in certain range of speeds; have the defencive function of general industry electric product overvoltage/undervoltage, overcurrent, stall, thereby possess easy to use and energy-conservation energy-saving multifunction smoke exhaust ventilator.
For solving the problems of the technologies described above, the utility model is realized as follows: energy-saving multifunction smoke exhaust ventilator described in the utility model is made up of system controller, input power supply, permanent-magnet brushless DC electric machine, blast wheel, smoke exhaust ventilator housing, user's keyboard interface and guidance lighting lamp; System controller is to be connected with input power supply, permanent-magnet brushless DC electric machine, user's keyboard interface, guidance lighting lamp by electric wire; Blast wheel is connected on the axle of permanent-magnet brushless DC electric machine; System controller, permanent-magnet brushless DC electric machine, user's keyboard interface, guidance lighting lamp all are installed on the smoke exhaust ventilator housing by hold-down screw.
Described input power supply is home-use general civil power, is used for providing power supply to smoke exhaust ventilator.
Described system controller adopts the intelligent chip with calculation function.
Good effect of the present utility model: energy-saving multifunction smoke exhaust ventilator described in the utility model, adopt intelligent chip as the control core, finish the instruction process of user's keyboard, regulate the rotating speed that motor operates in user's expectation, and regulate the motor operation according to the output current wave of motor, in order to optimize power factor, simultaneously, the operation and the source current of monitoring motor can be protected motor, make it not stall not overcurrent burn out overvoltage/undervoltage operation; Owing to use volume little, the permanent-magnet brushless DC electric machine that power density is big, torque characteristics is hard, and starting current is little, and operational efficiency is up to more than 85%, exceeds 33% at least than the efficient of traditional single-phase asynchronous motor, and one family can be saved more than the 100 degree electricity every year; Motor speed can design De Genggao, thereby makes the smoke exhaust ventilator volume littler, and material is more economized, and efficient is higher, more environmental protection and energy saving; Permanent-magnet brushless DC electric machine adopts 120 ° of square waves or 180 ° of sinusoidal wave position-sensor-free algorithms, saves electromechanical transducer, and simple in structure, easy to connect, reliability is higher.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

The specific embodiment
As shown in Figure 1, energy-saving multifunction smoke exhaust ventilator described in the utility model is made up of input power supply (7), system controller (1), permanent-magnet brushless DC electric machine (2), blast wheel (3), guidance lighting lamp (4), user's keyboard interface (5) and smoke exhaust ventilator housing (6); System controller (1) is connected with input power supply (7), permanent-magnet brushless DC electric machine (2), user's keyboard interface (5), guidance lighting lamp (4) by electric wire; Blast wheel (3) is connected on the axle of permanent-magnet brushless DC electric machine (2); System controller (1), permanent-magnet brushless DC electric machine (2), user's keyboard interface (5), guidance lighting lamp (4) all are fixedly mounted on the smoke exhaust ventilator housing (6).
Described input power supply (7) is home-use general civil power, is used for providing power supply to smoke exhaust ventilator.
Described permanent-magnet brushless DC electric machine (2) is that back-emf is the brshless DC motor of square wave or similar sine wave in theory, and the position-sensor-free algorithm of 120 ° of square waves or 180 ° of sine waves is adopted in the running of motor and control.
Described system controller (1) is to adopt the intelligent chip with calculation function as core, can finish Electric Machine Control, PFC, rotating speed computing function.
The course of work of the present utility model is:
System controller is the core of whole smoke exhaust ventilator in the energy-saving multifunction smoke exhaust ventilator described in the utility model, in the time elder generation's self check of starting working that powers on, comprising input supply voltage height, inner parameter examine, driving power height, user's keyboard signal correctness; If input supply voltage is in rated voltage 220VAC ± 15% scope, driving power voltage is in 15VDC ± 10%, and user's keyboard is unusual, then begins to monitor keyboard state, otherwise stops and the flashing light warning; Under the normal condition, the user is by " starting/stop " key, thus system controller then actuating motor drive and set rotating speed blast wheel to last time, if first start, then motor speed is by factory-default; Normally in service in starting, the user can stop smoke exhaust ventilator by " starting/stop " key, also can open or close indicator lamp, perhaps change motor speed, press the motor speed that can increase or reduce 50RPM at every turn by " quickening (+) " or " slowing down (-) " by " lamp " button; When acceleration and deceleration, according to actual condition, have the highest or the minimum speed restriction, prevent the too high or too low unnecessary noise of bringing of rotating speed.
In starting, if motor rotation blockage or starting difficulty then can be reset behind the autostop after a time, repeatedly still can not be normally after the starting flashing indicator light then, stopping alarm, preventing burning out motor because of motor or loading problem, thus therefore household electricity problem; Be in operation, if suddenly motor rotation blockage, block, current of electric increase suddenly too many, then can autostop, restart automatically after a time, prevent that motor from burning out and influence the normal electricity consumption of family; Be in operation, the user is by behind the key change rotating speed, and system controller can write down this value and preserve, and start next time just can be operated under this rotating speed.
Be in operation, system controller is the current waveform of monitoring motor in real time, under the necessary situation, can adjust current waveform, realizes the automatic adjusting of power factor, thereby reaches better electricity consumption effect, reduces the interference near electrical network.
