Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Fig. 1 is an embodiment theory structure schematic diagram;
Fig. 2 is the control circuit schematic diagram.
Among the figure: 1, motor; 2, electric machine casing; 3, frequency modulation motor drive circuit; 4, processor; 5, interface circuit; 6, status switch.
The specific embodiment
Fig. 1 has provided a kind of commercial kitchen exhaust system efficiency controller that is made of single blower fan and a plurality of cooking stove, and motor 1 is fixed in the electric machine casing 2, and motor 1 is fixed on the air exhaust passage together with motor blower fan.Cooking stove igniting operation provides a status switch 6, and the signal of telecommunication of this status switch 6 is electrically connected to interface circuit 5, the mode bit of processor 4 read interface circuit 5, and the operating frequency of decision frequency modulation motor drive circuit 3 is to satisfy the requirement of its air draft.If motor 1 rotational frequency is divided into third gear, as f1, f2, f3, when being operated in the f3 frequency, the exhaust air rate in the time of can satisfying three cooking stoves and work simultaneously.When being operated in the f2 frequency, the exhaust air rate in the time of can satisfying two cooking stoves and work simultaneously.When being operated in the f1 frequency, the exhaust air rate in the time of can satisfying a cooking stove job.Certainly above-mentioned just explanation in order to illustrate that its operation principle is done.
Fig. 2 is circuit theory diagrams, and single-chip microcomputer adopts P87LPC76X, is electrically connected with status switch on its P0 mouth, just 6 among Fig. 1.The P1.6 of P87LPC76X drives a relay by triode, and two on relay often leaves or normally-closed contact is electrically connected with the startup interface of frequency modulation motor, is used to control the rotation of motor and stop.The P2.0 of P87LPC76X and P2.1 are electrically connected with 1,2 pin of integrated circuit TLC5615, the output of TLC5615 is electrically connected with the in-phase end of operational amplifier by resistance R 2, inverting input is electrically connected with the centre cap of potentiometer W2 by resistance R 3, the end ground connection of W2, the other end is electrically connected with the emitter stage of triode Q1; The output of amplifier is electrically connected with the base stage of triode Q1 by resistance R 4; Triode Q1 colelctor electrode and power positive end are electrically connected with two frequency modulation ends of frequency modulation motor respectively, are used to control the operating frequency of motor.
