Description of drawings
The present invention will be further described below in conjunction with the embodiment accompanying drawing.
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 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.
The theme of above-mentioned explanation is: according to the position of cooking stove running status switch and the frequency of quantity decision frequency modulation motor, reach the best effort requirement of blower fan air draft, i.e. the switching value that the status switch of cooking stove operation provides is few, and the frequency of frequency modulation motor is low; The switching value that the status switch of cooking stove operation provides is many, the frequency height of frequency modulation motor.
