Abstract
The utility model relates to a control module, in particular to a control module for a household smoke exhaust machine. The control module for the household smoke exhaust machine comprises a smoke detection circuit, an infrared sensor detection circuit, a microprocessor control circuit and a smoke exhaust machine drive circuit, wherein output signals of the smoke detection circuit and the infrared sensor detection circuit are transmitted to the smoke exhaust machine drive circuit through the microprocessor control circuit. As the smoke detection circuit is adopted to monitor smoke signals, the control module for the household smoke exhaust machine can automatically open an air exhausting fan when people are in kitchen and smoke is produced, and can completely exhaust the smoke out and achieve intelligent automation control due to the fact that the air exhausting fan is always in a working state to exhaust the smoke when the people leave and the smoke exists.
Description
Technical field
The utility model relates to a kind of control module, particularly be a kind of family expenses induced-draft fan control module.
Background technology
Heating-up temperature commonly used was too high during steaming was prepared food makes grease gasification in the food form oil smoke to be suspended in the air, and particularly the oil smoke that generated of vigorous fire quick-fried is more, not only makes the kitchen environment greasy sticking hand that becomes; And, health is damaged, in order to improve kitchen environment owing to contain many carcinogenic materials that make us in the oil smoke; Reduce the injury of oil smoke, generally adopt household smoke exhaust ventilator to discharge oil smoke, still health; After finishing when cooking; Still be trapped in the kitchen, need long exhaust, can get rid of and finish with a large amount of pernicious gases.And traditional smoke exhaust ventilator need open to cut out and could accomplish exhaust work through manual work.
The utility model content
The purpose of the utility model is to overcome the problems referred to above, and a kind of family expenses induced-draft fan control module is provided.
The utility model solves the technical scheme that its technical problem adopted: family expenses induced-draft fan control module; Comprise Smoke Detection circuit, infrared induction testing circuit, microprocessor control circuit and induced-draft fan drive circuit, the output signal of said Smoke Detection circuit and infrared induction testing circuit transfers to the induced-draft fan drive circuit through microprocessor control circuit.
Said Smoke Detection circuit comprises adjustable resistance W1, the adjustable resistance W2 that Smoke Sensor WTT and output thereof connect.
Said infrared induction testing circuit is made up of the voltage amplifier of pyroelectric infrared sensor TN in coupling capacitance C1 is connected to YX7603 rpyroelectric infrared control integration module IC2.
The first order voltage amplifier of said rpyroelectric infrared control integration module IC2 is adjusted Amplifier Gain through external resistor R 1, the capacitor C2 of its 4th, 5 pin, the logical second level of the low-frequency band amplifier that the signal input after the amplification is made up of its 2nd, 3 pin CSET C5.
Be circumscribed with between the 17th, 18 pin of said rpyroelectric infrared control integration module IC2 and regulate monitoring human near the potentiometer W3 of surveillance area near distance.
Through adopting above-mentioned technical scheme, the beneficial effect of the utility model is: this device adopts Smoke Detection circuit monitoring smoke signal, as the people in the kitchen and when having smog to produce; Automatically open exhaust fan, when people leave, but when having smog when a little; Exhaust fan can be in running order always; Discharge fume, can smog have been arranged fully, realize intelligent automation control again.
Description of drawings
Fig. 1 is the circuit structure block diagram of the utility model.
Fig. 2 is the circuit theory diagrams of the utility model.
The specific embodiment
Like Fig. 1, shown in Figure 2; The family expenses induced-draft fan control module of the utility model; Comprise Smoke Detection circuit 1, infrared induction testing circuit 2, microprocessor control circuit 3 and induced-draft fan drive circuit 4, the output signal of said Smoke Detection circuit 1 and infrared induction testing circuit 2 transfers to induced-draft fan drive circuit 4 through microprocessor control circuit 3.
Said Smoke Detection circuit 1 comprises adjustable resistance W1, the adjustable resistance W2 that Smoke Sensor WTT and output thereof connect, and the output of Smoke Sensor WTT is connected to the 35th pin of microprocessor control circuit IC1 through resistance R 8, when gas sensor Smoke Sensor WTT surface adsorption when smog or imflammable gas; Its A, A1 interpolar resistance reduce, and at this moment owing to adjustable resistance W1, the dividing potential drop of W2 and A, A1 electrode resistance descends the current potential of Node B; C point current potential also and then descends; Microprocessor control circuit IC1 detected its 35th pin I/O end and was low level state this moment, judged through microprocessor control circuit IC1 internal processes and sent control signal, by the 28th pin output high level signal of microprocessor control circuit IC1; Through resistance R 7 current limlitings; Make triode Q1 conducting, relay J 1 adhesive, its contact J1-1 is by transferring normally closed point normal battle to; Make the exhaust blower energized, smog is discharged.When smog was not adsorbed in gas sensor Smoke Sensor WTT surface, its A, A1 interpolar resistance increased, and C point current potential also and then rises; Microprocessor control circuit IC1 detected its 35th pin I/O end and was high level state this moment; Send control signal through the judgement of microprocessor control circuit IC1 internal processes, the 28th pin output low level signal by microprocessor control circuit IC1 ends triode Q1; Relay J 1 discharges; Its contact J1-1 transfers normal battle to by normally closed point, makes exhaust blower lose power supply, shuts down.
Said infrared induction testing circuit 2 is made up of the voltage amplifier of pyroelectric infrared sensor TN in coupling capacitance C1 is connected to the 6th pin of YX7603 rpyroelectric infrared control integration module IC2; Be circumscribed with between the 17th, 18 pin of rpyroelectric infrared control integration module IC2 and regulate monitoring human near the potentiometer W3 of surveillance area near distance; The first order voltage amplifier of said rpyroelectric infrared control integration module IC2 is through the external resistor R 1 of its 4th, 5 pin, capacitor C2 adjustment Amplifier Gain and prevent self-excitation; The logical second level of the low-frequency band amplifier that the input of signal after the amplification is made up of its 2nd, 3 pin CSET C5, the signal after the amplification is through voltage comparator and latch, after time-delay etc. handles, by the 13rd pin output low level signal of rpyroelectric infrared control integration module IC2; The 23rd pin I/O end that this signal is input to microprocessor control circuit IC1 also is low level state; When microprocessor control circuit IC1 scans its 35th pin I/O end simultaneously for low level state, explained that the people is cooking, should open smoke exhaust ventilator; This moment, microprocessor control circuit IC1 sent control signal; By the 28th pin output high level signal of microprocessor control circuit IC1, resistance makes triode Q1 conducting through the R7 current limliting; Relay J 1 adhesive; Its contact J1-1 makes the exhaust blower energized by transferring normally closed point normal battle to, and smog is discharged.When smog was not adsorbed in gas sensor Smoke Sensor WTT surface, its A, A1 interpolar resistance increased, and C point current potential also and then rises; Microprocessor control circuit IC1 detected its 35th pin I/O end and was high level state this moment; Send control signal through the judgement of microprocessor control circuit IC1 internal processes, the 28th pin output low level signal by microprocessor control circuit IC1 ends triode Q1; Relay J 1 discharges; Its contact J1-1 transfers normal battle to by normally closed point, makes exhaust blower lose power supply, shuts down.Reach the automatic smoke exhausting function, realize intelligent control, can smog have been arranged, realize automation control again.
