Fig. 2 is that the fresh air linkage controller of the present invention connects the circuit diagram of range hood and fresh air motor-driven valve 3 respectively.
Embodiment
The present invention is described in detail below in conjunction with embodiment and accompanying drawing, it should be pointed out that described reality
Apply example and be intended merely to facilitate the understanding of the present invention, and do not play any restriction effect to it.
Embodiment 1
Referring to Fig. 1, range hood 0 is made up of body 1 and the two parts of fresh air linkage controller 2, and wherein body 1 includes casing, wind
Machine system and supply lines, casing are provided with smoke inlet and exhaust opening, and blower fan system includes fan assembly and illumination control apparatus, by
It is more ripe technology in the prior art in supply lines, casing, fan assembly and illumination control apparatus, here is omitted.
When range hood 0 is unlocked, fresh air linkage controller 2 is just automatically turned on because sensing the operating current of supply lines
The fresh air motor-driven valve 3 of kitchen VMC.It should be noted that fresh air linkage controller 2 can be provided at outside range hood 0
Portion, can also be built in inside range hood 0.
With reference to Fig. 2, fresh air linkage controller 2 specifically includes current-sensing circuit 21, signal isolation circuit 22, driving control
Circuit 23 processed, reduction voltage circuit 24, current rectifying and wave filtering circuit 25 and mu balanced circuit 26.Current-sensing circuit 21 is by being set in fume-exhausting
Current transformer HL1 on the supply lines of machine 0 senses the operating current of range hood 0 indirectly.Range hood 0 is unlocked fortune
Capable then have electricity in the supply lines of range hood 0, now current transformer HL1 can produce alternating current impression electricity under magnetic induction effect
Pressure, after the rectified bridge heap BD2 rectifications of the ac induction voltage, is filtered by electric capacity C4 and electric capacity C5, and the voltage of filtering is used to drive
The optocoupler U1 of dynamic signal isolation circuit 22 light emitting diode is lighted, so as to control the conducting of optocoupler U1 triode.Light
After electric capacity C3 Key ditherings of the Continuity signal of coupling U1 triode through drive control circuit 23, electric current is carried out by triode Q1 and put
Greatly, go driving closed type relay RL1 to connect so as to obtain sufficiently large power, and then control the fresh air motor-driven valve of VMC
3 rotate forward, so that fresh air valve is opened, reach fresh air valve and the effect of the intelligent automatic synchronization work of range hood 0, are now inhaling
Under the negative pressure ventilation of lampblack absorber 0, fresh air can be got in by outdoor through fresh air valve, the fresh air in kitchen is supplemented in time,
And then making the suction of range hood 0 more laborsaving, the air intake increase of range hood 0, oil smoke flies away reduction, and realizing improves air in kitchen
The purpose of quality.Electric capacity C5 wherein in current-sensing circuit 21 is the effect of High-frequency Interference pulse.
The core of signal isolation circuit 22 is the positive pole of light emitting diode in optocoupler U1, optocoupler U1 through resistance R7 and electric current
The input of sensor circuit 21 connects, and the emitter stage of triode is connected in the negative pole ground connection of light emitting diode, optocoupler U1 in optocoupler U1
Drive control circuit, it mainly considers to be due to that low pressure clutter on the supply lines of range hood 0 is more, causes current transformer
HL1 can produce insignificant interference alternating current, and now because the input of optocoupler is a light emitting diode, its conducting has a thresholding
Magnitude of voltage, the influence of interference alternating current can be dexterously filtered out using the presence of this threshold voltage, only in the electric current of supply lines
Reaching can just make optocoupler have output signal during certain value, the error that can solve to be produced by interference alternating current without unnecessary device.
Additionally, current-sensing circuit 21 and drive control circuit 23 are isolated with optocoupler U1, input/output signal passes through light
Coupling, what it was electrically entirely isolated, it is prevented effectively from by doing that drive control circuit 23 is brought to current-sensing circuit 21
Disturb and unsafe factor.
Drive control circuit 23 includes electric capacity C3, resistance R6, triode Q1, diode D1 and relay RL1.Wherein relay

The emitter stage of middle triode, triode Q1 base stage connects electric capacity C3 positive pole, electric capacity C3 negative pole ground connection through resistance R6.The electric capacity
C3 is debounce dynamic condenser, and it utilizes the principle that electric capacity both end voltage will not be mutated, and effectively overcomes by the illuminating lamp of range hood 0
Dash current caused by ON/OFF, can also improve the surge current as caused by the ON/OFF of range hood 0, that is, serve debounce action
With.It is to be acted on to play control loop and the electrical isolation of fresh air motor-driven valve 3 from relay RL1, it is to avoid each other
Interference.In addition, diode D1 positive pole contact relay RL1 coil also is born into pin, diode D1 negative pole contact relay RL1
The positive pin of coil, the back-emf that diode D1 is produced when being disconnected for relay RL1 coils provides discharge loop, to avoid damaging
Bad triode Q1.
Reduction voltage circuit 24 is made up of fuse F1, resistance R1, resistance R2 and electric capacity C1, after civil power is depressured through reduction voltage circuit 24
It is changed into low AC voltage, after the rectifier bridge stack DB1 rectifications of the rectified filter circuit 25 of this low AC voltage and circuit C2 filtering, becomes
Into DC voltage, after the voltage stabilizing of mu balanced circuit 26 that the DC voltage is made up of resistance R3 and voltage-regulator diode Z1 again, for driving
Control circuit 23 is powered, and without external power supply, realizes the low purpose of the small volume of fresh air linkage controller 2, cost.Wherein,
Fuse F1 plays a part of short-circuit protection.
To sense indirectly the operating current of range hood 0 from current transformer HL1, if range hood 0 needs automatically
The function of fresh air valve is opened, only a fresh air linkage controller 2 need to be installed additional, need not thus transform in range hood 0
Portion's circuit, very simple can carry out old machine upgrading.
It should be noted that relay RL1 can be closed type or open type.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than to present invention guarantor
The limitation of scope is protected, although being explained with reference to preferred embodiment to the present invention, one of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent substitution, without departing from the reality of technical solution of the present invention
