And supply nozzle 94 is disposed at the top of the dark bottom 42B1 (storing section 42B) darker than the shallow bottom 42B2 that holds water ware 42.Therefore, even if hold the lower limit water level that the water level of the storing section 42B of water ware 42 becomes regulation, saline solution directly supplies in the brine electrolysis of storing section 42B, also can prevent from separating out Sal holding water ware 42.

Store in the saline solution of Sal water tank 90 and extracted by the pump 95 that moves according to the control of control part 100.At the suction inlet 95A of this pump 95, be connected with the pipeline 92 that links with Sal water tank 90.On the other hand, at the outlet 95B of pump 95, be connected with the pipeline 93 that links with supply nozzle 94.These

pipelines

92,93 connect the water cover 30B that circles round from the water space 22A2 that circles round, and the circle round low humidity space 22B of space 22A2 adjacency of Xiang Yushui extends, and 22B disposes pump 95 in this low humidity space.Like this, because pump 95 is disposed at the lower low humidity space 22B of humidity ratio, so pump 95 can use the pump that does not apply anti-wet process etc.

Fig. 7 is the figure of the form of explanation brine electrolysis supply, and Fig. 7 (A) is the sketch map of the structure of expression air disinfecting apparatus, and Fig. 7 (B) is the figure that represents the structure of electrolysis bath 46 in detail.

Illustrate that with reference to this Fig. 7 brine electrolysis is to the supply of gas-liquid contact part 53.

If running operation air disinfecting apparatus 1, then the water level of storing section 42B is detected, and when this water level does not reach predetermined water level, opens water-supply valve 61 so that tap water supplies to and holds water ware 42, and this water level that holds the storing section 42B of water ware 42 reaches predetermined water level.

Water in the storing section 42B is extracted by circulating pump 44, and its part supplies to electrolysis bath 46.Shown in Fig. 7 (B), this electrolysis bath 46 has one for just another is negative paired

electrode

47,48, and by apply voltage between these

electrodes

47,48, the tap water that flow into electrolysis bath 46 is generated the brine electrolysis that contains active oxygen species by electrolysis.At this, active oxygen species refers to oxygen and its related substances of comparing common oxygen and having high oxidation activity more, is made as the active oxygen that comprises the so-called broad sense of ozone, hypohalogenous acids etc. and so in the active oxygen of the so-called narrow sense of superoxide anion, singlet oxygen, hydroxyl or hydrogen peroxide and so on.

Electrode 47, the 48th, for example matrix is the battery lead plate that titanium (Ti), thin layer are made of iridium (Ir), platinum (Pt).

With electrode 47 as anode electrode, with electrode 48 as cathode electrode, when applying voltage from external power source between to electrode 47 and electrode 48 and switching on, at the electrode 48 as cathode electrode, the hydrion (H in the water ⁺) and hydroxide ion (OH ^-) react according to following formula (1).

4H ⁺+4e ^-+(4OH ^-)→2H ₂+(4OH ^-) (1)

On the other hand, at the electrode 47 as anode electrode (anode), water carries out electrolysis according to following formula (2).

2H ₂O→4H ⁺+O ₂+4e ^- (2)

And, at electrode 47, the chloride ion that contains in the water (chloride ion: Cl ^-) react according to following formula (3), generate chlorine (Cl ₂).

2Cl ^-→Cl ₂+2e ^- (3)

And this chlorine reacts according to following formula (4) and water, generates hypochlorous acid (HClO) and hydrochloric acid (HCl).

Cl ₂+2H ₂O→HClO+HCl (4)

The hypochlorous acid that generates at electrode 47 is included in the active oxygen species of broad sense, has very strong Oxidation and discoloration.Dissolved hypochlorous aqueous solution and namely had following effect by the brine electrolysis that air disinfecting apparatus 1 generates: the various air purification effect such as decomposition of the deactivation of virus etc., sterilization, organic compound.

In addition, when having generated the strong hypochlorous acid of sterilizing power by

electrode

47,48, drip to gas-liquid contact part 53 if comprise this hypochlorous brine electrolysis from watering box 51, then the air that is blown out by Air Blast fan 31 contacts with hypochlorous acid at gas-liquid contact part 53.Thus, the virus of swimming in the air etc. is inactivated, and the odorous substance that contains in this air and hypochlorous acid react and is decomposed or ionizing and dissolving.Therefore, carry out degerming and the deodorization of air, cleaned air passes is discharged from gas-liquid contact part 53.

The mechanism of action as the deactivation of virus of being undertaken by active oxygen species etc. exemplifies influenza virus.Above-mentioned active oxygen species has the surface protein (furcella (スパイ Network)) that will infect the necessary influenza virus of influenza and destroys, eliminates the effect of (removing).When this surface protein is destroyed, the not combination of receptor (receptor) that influenza virus and influenza virus infection are required, infection is prevented from.Therefore, the influenza virus that swims in the air contacts with the brine electrolysis that comprises active oxygen species at gas-liquid contact part 53, thereby loses so-called appeal, and infection is prevented from.

Therefore, when even if this air disinfecting apparatus 1 for example is arranged at so-called large space such as kindergarten or primary school, middle school, senior middle school, nurse insurance facility, hospital, the air that is cleaned after (degerming, deodorization etc.) by brine electrolysis is spreaded all in large space on a large scale, can effectively carry out air sterilization and deodorization in the large space.

In addition, the concentration of the active oxygen species in the brine electrolysis is adjusted to the concentration that makes the deactivations such as virus of carrying out degerming.The concentration of active oxygen species is adjusted following carrying out, and namely adjusts the voltage that puts between electrode 47 and the electrode 48, and is adjusted at value of current flowing and conduction time thereof between electrode 47 and the electrode 48.Air disinfecting apparatus 1 preestablishes electrolytic conditions such as these voltages, electric current, conduction time.

Then, the brine electrolysis that drips to gas-liquid contact part 53 from watering box 51 is mobile downwards via gas-liquid contact part 53, and falls the water carrier 42A that holds water ware 42.The brine electrolysis of falling this water carrier 42A flows into storing section 42B via filter element 74.Then, utilize circulating pump 44 to extract again, supply to gas-liquid contact part 53 through electrolysis bath 46.Like this, in the structure of present embodiment, become water holding the circular type that water ware 42 refluxes, by effectively utilizing a spot of water, can effectively carry out the degerming of air for a long time.In addition, when waiting the water level that makes storing section 42B to reduce because of evaporation, open water-supply valve 61, by the admission port 64 an amount of tap waters of supplying with.

In addition, if the control by control part 100 comes driving pump 95, then store in the saline solution of Sal water tank 90 and be sucked out from sucking nozzle 90D, by

pipeline

92,93, supply to automatically from supply nozzle 94 and to hold water ware 42.Thus, hold water ware 42 even if the low tap water of cl concn supplies to, in the water that supplies to electrolysis bath 46, also comprise chloride ion.

The control system of present embodiment then, is described in detail in detail.

Fig. 8 is the functional block diagram of structure of the control system of expression air disinfecting apparatus 1.As shown in the drawing, except above-mentioned circulating pump 44, drain valve 83, pump 95, fan motor 107, make shutter CD-ROM drive motor 108 that automatic louver 20 opens and closes and also be connected with control part 100 respectively to the power supply unit 109 of each part mentioned above supply power, and move according to the control of control part 100.At this control part 100, be connected with the various switches that are equipped on guidance panel 106 and display lamp etc., and be connected with: first switch (FS) 43A and second switch (FS) 43B,

electrode

47,48, electrolysis bath switch (FS) 110 that detects the water level in the electrolysis bath 46 and the conductivity meter (electrical conductivity testing agency) 49 of the electrical conductivity between the detecting

electrode

47,48 that hold water ware 42.

In addition, it is electrolysis electrical conductivity of water in the electrolysis bath 46 with the electrical conductivity between the detecting

electrode

47,48 that conductivity meter 49 is disposed at electrolysis bath 46, but is not limited to this, as long as but be configured to instrumentation and holding the electrical conductivity of water that water ware 42 refluxes.

Control part 100 has: the microcomputer 101 that carries out the control of air disinfecting apparatus 1 integral body, storage is by microcomputer 101 control sequence of carrying out and the storage part 102 of controlling data such as parameter, carry out the timer 103 of timing action based on the control of microcomputer 101, detect the operation in the guidance panel 106 and content of operation outputed to microcomputer 101 input parts 104, and lighting of the display lamp of guidance panel 106 (omitting diagram) controlled wait and export the efferent 105 of the result of microcomputer 101.

Microcomputer 101 reads in and carries out the control sequence that is stored in advance in the storage part 102, and reads in the control parameter that is stored in storage part 102, makes the each several part action of air disinfecting apparatus 1.The microcomputer 101 of present embodiment is changed operation mode and is safeguarded and select action pattern the operation mode from air sterilization operation mode, water, this air sterilization operation mode carries out the air sterilization running to air sterilization, this water is changed the operation mode replacing and is stored the water in holding water ware 42 and supply with saline solution, and this safeguards operation mode discharge brine electrolysis.

Action pattern is selected the air sterilization operation mode usually.In the selection of this air sterilization operation mode, indicate the operation of action beginning at guidance panel 106, if microcomputer 101 is transfused to the information of this operation of expression from input part 104, then it makes the circulation of circulating pump 44 action and beginning water, and voltage is applied to

electrode

47,48 and generate brine electrolysis.And then microcomputer 101 makes 108 actions of shutter CD-ROM drive motor and makes automatic louver become open mode, after this, and the action of beginning fan motor 107, and beginning is blown by Air Blast fan 31.By above a series of action, the air sterilization running of beginning air disinfecting apparatus 1.Along with the beginning of this air sterilization running, microcomputer 101 illustrates the demonstration that is arranged in running by efferent 101.

In addition, along with the beginning of air sterilization running, microcomputer 101 is by the timing of 103 entry into service times of timer.Timer 103 can carry out the timing of the duration of runs cumulatively, after air disinfecting apparatus 1 stops the air sterilization running, when restarting the air sterilization running, also can proceed timing.And whenever the clocking value that reaches regulation (the accumulation duration of runs), timer 103 is informed microcomputer 101 with clocking value, and clocking value is resetted.

In the execution of air sterilization running, when detecting water level in the electrolysis bath 46 by electrolysis bath switch 110 and be low water level, and when detecting the water level that holds water ware 42 and be low water level by the first switch 43A that holds water ware 42, microcomputer 101 stops to apply voltage to

electrode

47,48, and stop the running of circulating pump 44 and fan motor 107, show warning by efferent 105.

In addition, in the operation that guidance panel 106 indicates action to stop, if the information of this operation of expression is input to microcomputer 101 from input part 104, then microcomputer 101 stops to apply voltage to

electrode

47,48, and circulating pump 44 is stopped.And then microcomputer 101 stops fan motor 107, and stops to be blown by Air Blast fan 31, after this, makes shutter CD-ROM drive motor 108 action and makes automatic louver 20 become closed condition.By above a series of action, the air sterilization of air disinfecting apparatus 1 running stops.When this air sterilization running stopped, microcomputer 101 stopped the demonstration of being undertaken by efferent 105 that is arranged in running, and the timing of the duration of runs of being undertaken by timer 103 is stopped.

In addition, when the accumulation of air sterilization running reached the stipulated time (for example 40 hours) duration of runs, when namely the clocking value of timer 103 reached predefined value, microcomputer 101 changed to water replacing operation mode from the air sterilization operation mode.Change at this water during the selection of operation mode, microcomputer 101 is carried out the water replacing running that is used for changing the brine electrolysis that has recycled.

Change in the running at water, microcomputer 101 is opened drain valve 83, and the water that holds in the water ware 42 is discharged to the outside.As mentioned above, if the water level of storing section 42B is lower than the lower limit water level of regulation, the first switch 43A that then holds water ware 42 switches to on-state.Therefore, when the first switch 43A connects, the water level that holds water ware 42 descends from prescribed level, store in the most of water that holds water ware 42 and be discharged from, the state that most of brine electrolysis that the water that becomes the circulating path that is present in brine electrolysis has used when being the air sterilization running is discharged from, the circulating path of this brine electrolysis comprise this and hold water ware 42, circulating pump 44, electrolysis bath 46, watering box 51 and gas-liquid contact part 53.Switch to connection if hold the first switch 43A of water ware 42, then microcomputer 101 is closed drain valve 83, finishes draining.

Then, microcomputer 101 is opened water-

supply valve

61, and 60 beginnings of self-water-supply portion are supplied with water to holding water ware 42.As mentioned above, if the water level of storing section 42B is higher than the set upper limit water level, the second switch 43B that then holds water ware 42 switches to connection.If the second switch 43B switches to connection, then owing in holding water ware 42, stored the required enough water of air sterilization running, so making water-supply valve 61 close and finish, microcomputer 101 supplies water.By above processing, finish to store the water replacing running in the replacing of the water that holds water ware 42.

And, in the present embodiment, when this water is changed operation mode, for the cl concn that makes the water that supplies to electrolysis bath 46 increases, saline solution is supplied to holds water ware 42.Below, illustrate that the saline solution of the supply of carrying out these water replacing runnings and saline solution is supplied with action.

Fig. 9 is the flow chart that the saline solution of expression air disinfecting apparatus 1 is supplied with action.During carrying out this saline solution shown in Figure 9 supply action, the function that microcomputer 101 is realized as controlling organization, the function that timer 103 is realized as time movement.

When the accumulation of air sterilization running reaches the stipulated time duration of runs, microcomputer 101 stops air sterilization running and the clocking value of timer 103 is resetted, and, carry out initialization, so that water described later is changed the count value N1 of running time counting number, the count value N2 of electrical conductivity detection time counting number and the count value N3 that saline solution is supplied with time counting number is [0] (step S1).

Then, microcomputer 101 is detected by conductivity meter 49 and is holding the electrical conductivity of water D1 (step S2) that water ware 42 refluxes, and judges whether electrical conductivity D1 is predefined regulation electrical conductivity Dm1 following (step S3).At this, be in order to infer the concentration of the ionic species in the water to detecting at the electrical conductivity of water that holds 42 backflows of water ware.For example, if the accumulation of air sterilization running surpasses 40 hours the duration of runs, the electrolysis electrical conductivity of water that has then recycled is often up to 6000～8000 μ S/cm.When the electrical conductivity of water that supplies to electrolysis bath 46 was too high, (for example, sulfate ion, calcium ion etc.) ratio increased the ion beyond the chloride ion, thereby can not generate the hypochlorous brine electrolysis that comprises the enough concentration that deactivations such as virus is required.Therefore, as the higher limit that is used for effectively generating the hypochlorous brine electrolysis that comprises the enough concentration that deactivations such as virus is required, the regulation electrical conductivity Dm1 of present embodiment is set at 2000 μ S (Siemens)/cm.

(step S3: not), microcomputer 101 judges whether the count value N1 of water replacing time counting number is (step S4) more than 5 times when electrical conductivity D1 is bigger than regulation electrical conductivity Dm1.The count value N1 that changes time counting number when water is than 5 times (step S4: deny) after a little while, in order to change the brine electrolysis that has recycled, microcomputer 101 is carried out above-mentioned water and is changed running (step S5), and the count value N1 that makes water change running time counting number only increases by 1 time.

Change running if finish water, the then running of microcomputer 101 beginning circulating pumps 44, make and supply to the new water that holds water ware 42 in the circulating path circulation of brine electrolysis, and, judge from water and change whether the time T 1 that finishes to begin to count that turns round is predefined stipulated time Tm1 (step S7).As long as this stipulated time Tm1 is set at and supplies to the new water that holds water ware 42 and flow into the required time enough of electrolysis bath 46, the stipulated time Tm1 of present embodiment is set at 5 minutes.

Change running from water and finish beginning, if through stipulated time Tm1 (step S7: be), then microcomputer 101 turns back to step S2 by making treatment step, detects electrical conductivity D1 again.

The result who carries out water replacing running repeatedly is, when the count value N1 of water replacing running time counting number reaches more than 5 times (step S4: be), it is bad that microcomputer 101 is judged as water replacing running, and display lamp is extinguished, and stops the running (step S8) of air disinfecting apparatus 1.

Electrical conductivity D1 is regulation electrical conductivity Dm1 when following (step S3: be), and microcomputer 101 is judged as the replacing of fully carrying out water, and stores this electrical conductivity D1 into storage part 102 (step S9).Usually, electrical conductivity of water is hundreds of little Siemens (for example being 100～200 μ S/cm) from the beginning, can generate the hypochlorous brine electrolysis that comprises the enough concentration that deactivations such as virus is required.On the other hand, in the air disinfecting apparatus 1 of present embodiment, owing to supply with the low tap water of cl concn that is difficult to electrolysis, so for the chloride ion in the water of the electrolysis bath 46 of increasing supply, driving pump 95, reversal brine tank 90 supply to an amount of saline solution and hold water ware 42 (step S10).This pump 95 is that the mode of 1～2ml turned round 1～2 second with the amount of dripping of saline solution.As mentioned above, owing to be provided with check valve 94A at supply nozzle 94, so saline solution drips fully, can be more accurately the saline solution of aim parameter be supplied to and hold water ware 42.

Then, microcomputer 101 judges whether the time T 2 that confession begins to saline solution is more than the predefined stipulated time Tm2 (step S11).As long as this stipulated time Tm2 is set at and supplies to the saline solution that holds water ware 42 and flow into the required time enough of electrolysis bath 46, the stipulated time Tm2 of present embodiment is set at 3 minutes.

Confession begins to saline solution, if through stipulated time Tm2 (step S11: be), then microcomputer 101 is detected by conductivity meter 49 and is holding the electrical conductivity of water D2 (step S12) that water ware 42 refluxes, and judges that the electrical conductivity D2 that supplies with after the saline solution compares with the electrical conductivity D1 that is stored in storage part 102 whether greater than more than the regulation electrical conductivity Dm2 (step S13).Like this, by being the electric conductivity difference that benchmark is judged the electrical conductivity D2 after electrical conductivity D1 before saline solution is supplied with and saline solution are supplied with regulation electrical conductivity Dm2, thereby can infer effectively by supplying with the concentration of the chloride ion that saline solution increases.

At this moment, low excessively as if the electrical conductivity of water that supplies to electrolysis bath 46, the chloride ion of the primary standard substance during then as generation hypochlorous acid becomes not enough, can not generate the hypochlorous brine electrolysis that comprises the enough concentration that deactivations such as virus is required.Therefore, regulation electrical conductivity Dm2 is set to, and can generate the hypochlorous brine electrolysis that comprises the enough concentration that deactivations such as virus is required the duration of runs in the accumulation of stipulating.And this regulation electrical conductivity Dm2 is set to, and the existing electrolytic condition that supplies to tap water with salt with ormal weight (for example 0.5g) is roughly the same.Thus, owing to can use existing electrolytic condition, so that the setting of electrolytic condition becomes is easy.And the electric current that flows between electrode 47 and electrode 48 during because of electrolysis and the electric current of existing situation so even if use the low tap water of cl concn, do not increase loads to

electrode

47,48, do not need to increase replacing

electrode

47,48 frequency about equally yet.Regulation electrical conductivity Dm2 sets and gets final product to satisfy the above-mentioned mode that imposes a condition, and the regulation electrical conductivity Dm2 of present embodiment is set to 500 μ S/cm.

(step S13: not) when electrical conductivity D2 compares less than regulation electrical conductivity Dm2 with electrical conductivity D1, the count value N2 that microcomputer 101 makes electrical conductivity detect time counting number only increases once (step S14), and judges whether count value N2 is (step S15) more than 3 times.(step S15: not), microcomputer 101 turns back to step S11 by making treatment step, detects electrical conductivity D2 again when the count value N2 of electrical conductivity detection time counting number is less than 3 times.Thus, even if former thereby cause saline solution to flow into the time delay of electrolysis bath 46 because of certain, also can detect electrical conductivity D2 effectively.The result who detects electrical conductivity D2 repeatedly is, when the count value N2 of electrical conductivity detection time counting number reaches more than 3 times (step S15: be), the count value N3 that microcomputer 101 makes saline solution supply with time counting number only increases once (step S16), and judges whether count value N3 is (step S17) more than 8 times.

(step S17: not), microcomputer 101 turns back to step S10 by making treatment step to the count value N3 that supplies with time counting number when saline solution, supplies with saline solution again during less than 8 times.When the count value N3 of saline solution supply time counting number reaches more than 8 times (step S17: be), microcomputer 101 is judged as in Sal water tank 90 does not have saline solution, and display lamp is extinguished, and stops the running (step S18) of air disinfecting apparatus 1.

When electrical conductivity D2 compares (step S13: be) when above greater than regulation electrical conductivity Dm2 with electrical conductivity D1, be judged as and carry out the required enough saline solutions of air sterilization running and supplied to and hold water ware 42, finish saline solution and supply with action, and restart the air sterilization running.

Supply to the water of electrolysis bath 46, be supplied to the saline solution that comprises chloride ion, thereby chloride ion increases, therefore, if by electrolysis, then this chloride ion reacts according to above-mentioned formula (3) and (4), generates hypochlorous acid and hydrochloric acid.Therefore, in the air disinfecting apparatus 1, hold water ware 42 even if the low tap water of cl concn is fed into, also can generate the brine electrolysis that comprises active oxygen species, and can play enough air purification effect (deactivation of virus etc., sterilization, deodorization).

In addition, air disinfecting apparatus 1 constitutes, be not to supply with saline solution when holding water ware 42 supplying water at every turn, but only change under the situation of running having carried out water, namely after the brine electrolysis that will hold water ware 42 is discharged, supply water to and supply with saline solution when holding water ware 42.By this structure, because of reasons such as the water level that holds water ware 42 have reduced, supply water to when holding water ware 42 not carrying out draining and not supply with saline solution, so control is oversimplified.

And, when air disinfecting apparatus 1 does not use because of the friendship in season etc. for a long time, mobile air disinfecting apparatus 1 the place is set the time or when carrying out the safeguarding of air disinfecting apparatus 1 etc., need will store in the water that holds water ware 42 and discharge.Therefore, be provided with the draining button (not shown) of accepting drain operation at aforesaid operations panel 106, this drain operation indication will store in the water that holds water ware 42 discharges.

If the draining button of operating operation panel 106, then microcomputer 101 selects to safeguard operation mode.This safeguards in the selection of operation mode that microcomputer 101 is after the circulating path to brine electrolysis cleans, and execution will store the maintenance running of discharging in the water that holds water ware 42.Along with this safeguards the beginning of running, microcomputer 101 is irrelevant the duration of runs with the accumulation of air sterilization running, selects above-mentioned water to change operation mode, and carries out saline solution and supply with action.That is, microcomputer 101 is supplied with saline solution to supplying in the new water that holds water ware 42 after carrying out water replacing running.Supply with action if finish saline solution, then microcomputer 101 makes the new water cycle that chloride ion has increased, generates to comprise the brine electrolysis of active oxygen species, and utilizes this brine electrolysis to clean the cleaning action of brine electrolysis circulating path.Then, microcomputer 101 will store in the water discharge of holding water ware 42 and make the state that water ware 42 becomes sky that holds, and, in order to prevent that assorted bacterium is in gas-liquid contact part 53 breedings, within a certain period of time, drive Air Blast fan 31 and blow wind to gas-liquid contact part 53, so that gas-liquid contact part 53 dryings.

By above processing, if the drain operation according to user begins to safeguard running, even if then the accumulation of air sterilization running does not reach the stipulated time duration of runs, also can select water to change operation mode, after water is changed running, automatically saline solution is supplied to and hold water ware 42.Therefore, in the air disinfecting apparatus 1, even if supplying to, the low tap water of cl concn holds water ware 42, by supplying with saline solution to supplying in the new water that holds water ware 42, thereby also can generate the brine electrolysis that comprises active oxygen species, and utilize this brine electrolysis clean cycle path.

Explanation as previously discussed according to above-mentioned embodiment, constitutes, and when selecting water to change operation mode, makes pump 95 actions of Sal water tank 90, holds water ware 42 thereby saline solution supplied to.By this structure, supply with owing to having supplied in the new water that holds water ware 42 from trend at saline solution after the draining, so can not make user feel numerous and diverse, can guarantee eletrolyzable cl concn.
