Embodiment
Following according to drawing explanation embodiments of the present invention.
At first, Fig. 1 is the structure chart of expression embodiments of the present invention.In Fig. 1,10 is ion generator (ionizer) main body of straight flow, at the rear, inside of shell 11, and the positive lateral electrode 12P and the minus side electrode 12N of configuration needle-like, and, in the place ahead, inside of shell 11, the fan 13 of configuration air-supply usefulness.In addition, the electrode of positive side and minus side can be a plurality of respectively.
In the place ahead of fan 13, configuration ion balance sensor 14, and with the corresponding position of minus side electrode 12N in the place ahead of fan 13, dispose ionic weight transducer 15 respectively.
At this, how much corresponding ion balance sensor 14 for example can use the conductivity protection component (guard electrode) in the place ahead that is disposed at fan 13 for measuring ionic currents with cation amount and negative ion amount to detect the transducer of ionic equilibrium.In addition, ionic weight transducer 15 is for detecting the transducer of the ionic current of sending via fan 13 around the minus side electrode 12N that anion produced, and constitutes by ionic current being converted to semiconductor transducer that voltage exports again etc.
The output signal of ion balance sensor 14 inputs to amplifier 21P, aligns the voltage that applies of lateral electrode 12P with control, and the output signal of ionic weight transducer 15 inputs to amplifier 21N, with the apply voltage of control to minus side electrode 12N.
These two amplifier 21P, the output signal of 21N inputs to CPU22, and this output signal inputs to the high voltage generating circuit 24P of positive lateral electrode 12P side and the high voltage generating circuit 24N of minus side electrode 12N side respectively via voltage-regulating circuit 23.Put on the positive lateral electrode 12P from the positive high voltage of high voltage generating circuit 24P output, the negative high voltage of exporting from high voltage generating circuit 24N puts on the minus side electrode 12N.
In addition, on above-mentioned CPU22, be connected with display control circuit 25, on this display control circuit 25, be connected with and be used for pointing out the cleaning of each electrode 12P, 12N and carry out display lamp 26a that bright lamp shows and show the display lamp 26b that warns when cleaning when not finishing (above-mentioned display lamp 26a during certain more than still for show state time) bright lamp.
In addition, in above-mentioned structure, the spare part beyond the ion generator main body 10 constitutes controller, and the structure including components therein of this controller is in shell 11.In addition, amplifier 21P, 21N, CPU22, voltage-regulating circuit 23, high voltage generating circuit 24P, 24N constitute the control device in the technical scheme.
The action of this execution mode then, is described.
In the present embodiment, CPU22 detects positive and negative ionic equilibrium from the output signal of ion balance sensor 14, and computing puts on the positive voltage on the positive lateral electrode 12P, exports it to voltage-regulating circuit 23.In voltage-regulating circuit 23, generate the control signal of the output voltage be used for taking place the computing of CPU22 institute, export it to high voltage generating circuit 24P.
On the other hand, CPU22 detects negative ion amount from the output signal of ionic weight transducer 15, and computing puts on the negative voltage on the minus side electrode 12N, exports it to voltage-regulating circuit 23.In voltage-regulating circuit 23, generate the control signal of the output voltage be used for taking place the computing of CPU22 institute, export it to high voltage generating circuit 24N.
Now, when the negative ions amount was uneven, it is superfluous or not enough that ion balance sensor 14 detects the cation amount, and this detection signal is input to CPU22 via amplifier 21P.CPU22 reduces or replenishes the cation of deficiency in order to make superfluous cation, and computing puts on the required positive voltage of positive lateral electrode 12P, and aligns the voltage that applies of lateral electrode 12P by voltage-regulating circuit 23 and high voltage generating circuit 24P control.
By above-mentioned action, can make cation amount and negative ion amount keep about equally removing electronic work under the state of ionic equilibrium.
In addition, because of long-term the use causes electrode 12P, 12N is polluted, and the result reduces when ionic weight takes place, and then ionic weight transducer 15 detected negative ion amounts also reduce.The output signal of this ionic weight transducer 15 is input to CPU22 via amplifier 21N.
In CPU22, computing puts on the required negative voltage of minus side electrode 12N for the anion that increase reduced, and via voltage-regulating circuit 23 and high voltage generating circuit 24N, the voltage that applies to minus side electrode 12N is increased.So, when its result destroys when ionic equilibrium, can align the voltage that applies of lateral electrode 12P by the control system control of using aforementioned ion balance sensor 14, thus the ionic equilibrium of keeping.
In the above description, align the voltage that applies of lateral electrode 12P according to the output signal control of ion balance sensor 14, and according to the apply voltage of the output signal of ionic weight transducer 15 control to minus side electrode 12N, but also can be, and align the voltage that applies of lateral electrode 12P according to the output signal control of ionic weight transducer 15 according to the voltage that applies of the output signal of ion balance sensor 14 control to minus side electrode 12N.
In addition, when detecting the negative ion amount minimizing by ionic weight transducer 15, CPU22 judges needs cleaning electrode when detected ionic weight is lower than default value, can be via display control circuit 25, and bright lamp shows the wherein display lamp 26a on one side.
The display lamp 26a of this cleaning usefulness also can show above under the situation of set point at the voltage that applies to minus side electrode 24N or positive lateral electrode 24P that CPU22 controlled.
Above when continuing bright lamp during certain when cleaning with display lamp 26a, that is, and when the cleaning of electrode is not implemented and caused taking place ionic weight still seldom the time, via the display lamp 26b of display control circuit 25 bright lamps demonstration another sides, by way of caution.In the case, can show cleaning display lamp 26a by yellow next bright lamp, show to warn with the next bright lamp of redness and use display lamp 26b.
As mentioned above, show the necessity that to strengthen reminding cleaning electrode to the user if carry out two stage bright lamp.
