On the other hand, as shown in Figure 5, electrolysis cells 5 is connected with not shown water-supply source via sparge pipe 6, and is connected with air sterilization portion 4 via brine electrolysis supplying tubing 51.
This water-supply source; Both can supply with water to electrolysis cells 5 via sparge pipe 6, also can, for example sparge pipe 6 is connected with water supply pipe (omit and illustrate); The municipal water (running water) that to supply with via water supply pipe is as water-supply source; Also can, for example sparge pipe 6 and feed trough (omitting diagram) etc. are connected, with the water that stores in the feed trough as water-supply source.At this, the water that feed trough etc. store can be as running water etc., contains the water of chloride ion plasma kind in advance, also can be the thin water of well water plasma kind concentration.Below, these water of supplying with from water-supply source via sparge pipe 6 are called " running water etc. ".
Sparge pipe 6 has: the water-supply source tube connector 61 that is connected with water-supply source (water-supply source connecting portion) and be assigned to the distributing pipe 62 (dispenser) of electrolysis cells 5 from water-supply source tube connector 61 to each indoor unit 2 branch, with running water etc.In addition, on water-supply source tube connector 61 and distributing pipe 62, be respectively arranged with switch valve 63,64,, supply with running water etc. to electrolysis cells 5 through opening these switch valves 63,64.
In addition, as water-supply source, its structure also can be, and retention basin 71 is equipped on the floor with the state that can be provided with waits and be disposed near the floor, via pipe arrangement 72 the water-supply source tube connector 61 that grade under retention basin 71 and the floor sets is connected.Like this, through not being to be disposed at the high-order bit, but near the floor, can easily carry out the supply of medicament in retention basin 71 etc. with retention basin 71.
Sparge pipe 6 is provided with medicament interpolation portion 7, and interpolation contains the medicament of regulation ion species in water-supply source tube connector 61, to the running water of supplying with from water-supply source etc.This medicament interpolation portion 7 has: retention basin 71, and it stores the medicament that contains the regulation ion species; Pipe arrangement 72, it connects this retention basin 71 and water-supply source tube connector 61; Flow rate regulating valve 73, it is arranged at this pipe arrangement 72; Conductance detects meter 74, and it detects the conductances of supplying with from water-supply source such as running water; Control device (omit diagram), it is based on the conductance that detects running water that meter 74 detects etc. through conductance, and the aperture of adjustment flow rate regulating valve 73 is with the amount of control medicament of interpolation in running water etc.
At this, the ion species of regulation is preferably halide ion (X -), be preferably chloride ion (Cl especially -).In running water etc., during the interpolation chloride ion,, can use sodium chloride (NaCl) as the ion species of regulation as medicament.Sodium chloride can use salt etc. to add in running water etc. with solid state, also can be as saline solution with the interpolation in running water etc. of the state that is adjusted into the aqueous solution.In first embodiment, applied structure is that the saline solution of adjusting to normal concentration is stored in the retention basin 71.Through as the state of saline solution with the aqueous solution, the ion species of regulation is added in the running water etc., thus can be safely and easily in running water etc., add the ion species of stipulating.
Conductance detects meter 74 and is used to detect the conductance that flow into the running water etc. of sparge pipe 6 from water-supply source.
At this, detect the conductance of running water etc., be in order to infer the ion species concentration in the running water etc.That is, the running water of same amount etc. is supplied in the electrolysis cells 5, even if between electrode with the electric current energising of same current density, because of the chloride ion concentration in the running water etc. etc. makes the hypochlorous acid isoreactivity oxygen kind concentration change that generates at electrolysis cells 5.Therefore, according to the ion species concentration that contains in the running water etc., there is the situation that is difficult to generate effectively the brine electrolysis that contains active oxygen species.So, make its structure do, based on the conductance of the running water of supplying with from water-supply source etc., infer chloride ion plasma kind concentration, concentration is by inference added the ion species of regulation.At this moment; Ion species concentration when the running water of supplying with from water-supply source etc. be below the normal concentration (for example; During chloride ion, for 30ppm with inferior) time, its structure both can be the valve opening of adjustment flow rate regulating valve 72 to add the ion species of ormal weight; Also can be the variation of corresponding conductance and adjust the valve opening of flow rate regulating valve 72, so that the ion species concentration of the running water of supplying with in the electrolysis cells 5 etc. reaches the value of regulation.
Then, at the water-supply source connecting portion, the ion species of regulation is added, and the running water etc. that contains the above ion species of normal concentration is supplied with by the electrolysis cells 5 to each indoor unit 2 through the distributing pipe 62 of sparge pipe 6.
Because of being added the ion species of regulation in the running water supplied with in the electrolysis cells 5 etc., sparge pipe 6 is preferably for the running water that contains these regulation ion species etc. to be had patience, can not cause the raw material of deteriorations such as sparge pipe 6 gets rusty.As the sparge pipe 6 of this raw material, for example, can use plastic tube or pass through the inner multiple tube of plastic coat pipe made of iron.As plastic tube, for example enumerate vinyl chloride pipe, polyethylene pipe, Polybutylene Pipe, crosslinked polyethylene pipe etc.In addition, as multiple tube, enumerate for example vinyl chloride lined steel pipe (chlorine PVC ラ イ ニ Application グ steel pipe).
In addition, as shown in Figure 1, be arranged at the control device 200 of indoor unit 2, connect Air Blast fan 22, electrolysis cells 5, and switch valve 63,64 respectively through distribution 201.The running that this control device 200 can be controlled Air Blast fan 22 begins/stops, and the change of the current value can control electrolysis cells 5 electrolysis the time.In more detail, this aircondition 100 has through carrying out the cleaning operation mode of these controls with scavenging air degerming portion 4.
So-called cleaning operation mode is meant following pattern, that is, and and between indoor unit 2 on-stream periods; For example; The brine electrolysis of about 2ppm concentration is supplied in the air sterilization portion 4, and under the situation of rated condition, the brine electrolysis concentration of supplying with in the concentration ratio running to this air sterilization portion 4 is high (for example; More than the 10ppm) brine electrolysis, scavenging air degerming portion 4.
This cleaning operation mode for example carries out following running control.
(1) indoor unit 2 running stopping periods
The running of indoor unit 2 when for example stopping more than three hours continuously, becomes air sterilization portion 4 and does not also supply with brine electrolysis.Therefore, air sterilization portion 4 is mould because of drying generates in inside, or the anxiety of other germ reproduction is arranged.In order to prevent this situation and, to be necessary to supply with high-concentration electrolytic water to air sterilization portion 4 effectively with its cleaning.
At this moment, the running that control device 200 detects indoor unit 2 stops, for example; Control as follows; That is, three hours open at interval switch valve 63,64, and the current value that electrolysis cells 5 is used for electrolysis is set at high value; Generate high-concentration electrolytic water, this brine electrolysis is supplied to air sterilization portion 4.Thus, through cleaning operation mode, interval scavenging air degerming portion 4 that can three hours.In addition, the above-mentioned time interval (three hours) is an example, also can be set at other suitable time interval.
(2) between indoor unit 2 continuous on-stream periods
The running of indoor unit 2 for example during 24 hours of continuous run, can be adhered to a lot of pollutants etc. in the air sterilization portion 4.Therefore, be necessary regularly high-concentration electrolytic water to be supplied to air sterilization portion 4.
At this moment, control device 200 detects 24 hours of continuous run, for example, controls as follows, that is, at dead of night the time period, make Air Blast fan 22 only stop the stipulated time.Then, the current value that electrolysis cells 5 is used for electrolysis is set at high value, generates high-concentration electrolytic water, and this brine electrolysis is supplied to air sterilization portion 4.Thus, through the cleaning operation mode, can be in official hour section scavenging air degerming portion 4.
In addition, this control device 200 also can be also used as the control device that the switching of cross valve 13, the aperture control of flow rate regulating valve 73 etc. are used to control this aircondition 100.
Fig. 5 is the synoptic diagram that expression connects the pipe arrangement path of air sterilization portion 4 and electrolysis cells 5.
The brine electrolysis supplying tubing 51 that connects air sterilization portion 4 and electrolytic cell 52 is provided with from the bypass pipe arrangement (bypass flow path) 206 of the medial fascicle in this pipe arrangement path.The 206a of discharge portion of this bypass pipe arrangement 206 extends to the drip pan 43 of air sterilization portion 4 always, with the brine electrolysis that will send here from electrolysis cells 5 with after the incrustation scale stated be discharged to drip pan 43 through the bypass pipe arrangement.
In addition, on the brine electrolysis supplying tubing 51, the position in the downstream of the position of bypass pipe arrangement 206 branches is provided with the switch valve 202a of scalable flow, on bypass pipe arrangement 206, also is provided with the switch valve 202b of scalable flow.These switch valves 202a, 202b are connected with control device 200 via holding wire 301,302, based on the Signal Regulation flow from control device 200.
In addition, control device 200 is connected with the last supply unit 205 of electrode 53a, 53b that is used for voltage is applied to electrolytic cell 52 via holding wire 306.This supply unit 205 uses distribution 307 to be electrically connected with electrode 53a, the 53b of electrolytic cell 52, and electrolytic cell 52 can make positive pole and the negative pole counter-rotating of electrode 53a, 53b based on the signal from control device 200.
Through such structure, the electrode 53a, the 53b that voltage are applied to electrolytic cell 52 are last, carry out electrolysis, and then owing to be used for generating the calcium ion that running water contained or the magnesium ion of brine electrolysis, incrustation scale 204 is last attached to electrode 53a, 53b.Therefore, be necessary regularly to remove this incrustation scale 204, reduce to prevent electrolysis performance and durability in the electrolytic cell 52 from electrode 53a, 53b.Removing according to the following steps of this incrustation scale carried out.
1) control of switch valve 202a, 202b
During normal operation (when brine electrolysis is supplied with), switch valve 202a is opened, and through switch valve 202b is closed, the brine electrolysis that generates at electrolytic cell 52 supplies to air sterilization portion 4 from brine electrolysis supplying tubing 51, and it does not flow into bypass pipe arrangement 206.On the other hand, when removing descale 204, close switch valve 202a, and open switch valve 202b.Thus, the incrustation scale of removing 204 does not flow into brine electrolysis supplying tubing 51, is discharged to drip pan 43 through bypass pipe arrangement 206.
2) counter-rotating of the polarity of electrode 53a, 53b
Through signal from control device 200, the opposite polarity when making the polarity inversion of electrode 53a, 53b be electrolysis.Though incrustation scale 204 is formed on the electrode of cathode side, through reversed polarity, from the possibility increase of stripping electrode.Therefore, the incrustation scale of removing 204 is discharged to drip pan 43 through bypass pipe arrangement 206.
According to the aircondition of first embodiment of the invention, when electrolysis cells 5 electrolysis running water etc., be applied to electrode 53a, the last electric current of 53b through control, can freely adjust by the hypochlorous acid concentration in the brine electrolysis of electrolysis.So, compare the brine electrolysis concentration that is used to carry out air sterilization of supply, can supply to air sterilization portion 4 by the brine electrolysis that concentration is higher, so, can use this high-concentration electrolytic water scavenging air degerming portion 4.Therefore, need not air sterilization portion 4 be taken out from the inside of indoor unit 2, promptly capable of washing, so can easily carry out cleaning operation.
In addition,, be used for the cleaning operation mode of scavenging air degerming portion 4, do not need manually-operated through implementation based on the control of control device 200, can be regular scavenging air degerming portion 4.
And, when scavenging air degerming portion 4, stop, thereby the smell that high-concentration electrolytic water is sent can initiatively not be diffused into the outside through the running that makes Air Blast fan.
This cleaning operation mode for example, is supplied with high-concentration electrolytic water with three hours intervals at indoor unit 2 running stopping periods to air sterilization portion 4, so can prevent the dry of air sterilization portion 4 or in the breeding of the germ such as mould of inside.Therefore, can the inside of indoor unit 2 be remained on the state of cleaning.
In addition, this cleaning operation mode is between indoor unit 2 continuous on-stream periods, for example; In the time of seldom late into the night of user, carry out the supply of high-concentration electrolytic water; So, even if the aircondition of 24 hours of continuous run also can regularly carry out the cleaning of air sterilization portion 4.Therefore, can the inside of indoor unit 2 be remained on the state of cleaning.
In addition, according to first embodiment, because of air sterilization portion 4 is arranged at blow-off outlet 32 1 sides of indoor unit 2, so the hypochlorous acid isoreactivity oxygen kind that from the air that this air sterilization portion 4 blows out, is contained can directly not be directed in the indoor heat converter 21.Therefore, can prevent to corrode indoor heat converter 21 through hypochlorous acid isoreactivity oxygen kind.
According to the aircondition of first embodiment of the invention,, can the incrustation scale 204 that generate at electrolysis cells 5 (electrolytic cell 52) be flowed to bypass pipe arrangement 206 through being provided with from the bypass pipe arrangement 206 of the medial fascicle of brine electrolysis supplying tubing 51.Therefore, incrustation scale is not supplied with to air sterilization portion 4, thus can be owing to incrustation scale 204 contaminated air degerming portions 4.
In addition, switch valve 202a, 202b are set, when running well and the switching of incrustation scale switch valve when removing, can reliably the incrustation scale of removing 204 be flowed to bypass pipe arrangement 206 through control.Therefore, incrustation scale is not supplied with to air sterilization portion 4, thus can be owing to incrustation scale 204 contaminated air degerming portions 4.
And, extend to the drip pan 43 of air sterilization portion 4 through the 206a of discharge portion that makes bypass pipe arrangement 206 always, can be with the incrustation scale of discharging with discharging through the brine electrolysis after the air sterilization portion.Therefore, the device that is used for the incrustation scale removed is discharged etc. can be by shared, thus the number of components that can subdue aircondition 100 with reduce cost.
And, carry out the counter-rotating of polarity of switching and electrode 53a, the 53b of switch valve 202a, 202b because of signal, so the incrustation scale that for example can be used for regularly removing descale is automatically removed operation modes such as running based on control device 200.Its result can obtain the aircondition 100 that can more effectively turn round.
