The specific embodiment
Below, with reference to accompanying drawing an embodiment of the present invention is described.Fig. 1 is the cutaway view of expression aircondition body and decoration panel, and Fig. 2 is the upward view of expression aircondition body.
In Fig. 1 and Fig. 2; Reference numeral 1 expression aircondition; This aircondition 1 is with not shown off-premises station combination and have the kind of refrigeration cycle that is made up of compressor, outdoor heat converter etc., and as shown in Figure 1, suspends in midair and is fixed in the ceiling space 41 in house 40.Form in Fig. 1 and Fig. 2 is the embodiment of four directions to ceiling boxlike (four directions is to courtyard カ セ Star ト shape) aircondition 1; Have aircondition body 2 and decoration panel 3; Central authorities at this decoration panel 3 offer suction inlet 4, around the suction inlet 4 of decoration panel 3, offer blow-off outlet 5.Four bolts 42 40 are set to vertical lower from the house, and these four bolts 42 are separately fixed on the lifting metal installed part 43 of aircondition body 2.
In aircondition body 2, dispose fan electromotor 6, indoor fan 7 (turbofan), demarcation strip 8, draining pump 12, discharge outlet 13, refrigerant piping 14, electrical installation box 15, heat exchanger 16 etc., below this heat exchanger 16, dispose the drain pan 22 of the discharge water that reception flows down from this heat exchanger 16 with draining pump controlling organization equal controller.
Fig. 3 is the figure of drain pan.
In Fig. 3, below heat exchanger 16, be provided with drain pan 22.Be formed with lower draining in the bottom of this drain pan 22 and accumulate the 22A of portion, run down into discharge water in the drain pan 22 and flow into this draining and accumulate the 22A of portion.In addition, accumulate the 22A of portion, dispose level sensor 30 and draining pump 12 as the water level detecting mechanism of detecting the discharge water water level in draining.Be connected with for example draining pump driving mechanism 23 such as DC motor at this draining pump 12, and then, be connected with the draining pump controlling organization 24 of the startup that can control this draining pump 12/stop and rotating speed at this draining pump driving mechanism 23.The water level that this draining pump controlling organization 24 detects based on level sensor 30 makes draining pump 12 actions.
Particularly; Level sensor 30 has common electrode 31 and the lower limit detecting electrode 32 and upper limit detecting electrode 33 relative with this common electrode 31; When the discharge water water level rises to the position of upper limit detecting electrode 33; Draining pump controlling organization 24 makes draining pump 12 running, when water level drops to the lower lower position of lower end 32A (Fig. 5) than lower limit detecting electrode 32, draining pump 12 is stopped.
Between common electrode 31 and lower limit detecting electrode 32 and upper limit detecting electrode 33, be applied with voltage respectively; When between common electrode 31 and lower limit detecting electrode 32 or upper limit detecting electrode 33, having discharge water; Because predetermined electric current (for example; 50mA) flow, therefore, detect this electric current and be judged to be water via discharge water.On the other hand, when predetermined electric current does not flow, be judged to be anhydrous.
In this embodiment; Being configured to common electrode 31 extends to draining always and accumulates near the bottom surface of the 22A of portion; Lower limit detecting electrode 32 extends to the position with the roughly the same height of suction inlet 12A of draining pump 12 always, and upper limit detecting electrode 33 extends to the position lower than the bottom surface 16A of heat exchanger 16 always.Thus, when water level is low to can not use the position of draining pump 12 drainings the time, stop draining pump 12 immediately and dally to prevent this draining pump 12; And; When the water surface during,, prevent that heat exchanger 16 is immersed in the discharge water through running draining pump 12 near the bottom surface 16A of heat exchanger 16.
In addition, whether draining pump controlling organization 24 has sensing chamber's internal fan 7 in indoor fan running the stopping testing agency 26 (being designated hereinafter simply as fan running testing agency) of running and the speed setting mechanism 27 that sets the rotating speed of draining pump 12.
In the running of draining pump 12; When fan running testing agency 26 detects indoor fan 7 when on-stream; Speed setting mechanism 27 is a maximum (top) speed with the speed setting of draining pump 12; And output to draining pump driving mechanism 23, after fan running testing agency 26 detects indoor fan 7 and stops, but the minimum speed of draining is outputed to draining pump driving mechanism 23.In addition, draining pump driving mechanism 23 makes draining pump 12 runnings with the rotating speed from 27 outputs of speed setting mechanism.
In addition, the discharge outlet 13 at draining pump 12 is connected with the drainpipe 19 that outside machine, carries out draining.This drainpipe 19 has the rising portions 19A that extends to the top, if draining pump 12 shuts down, the discharge water that then remains in this rising portions 19A is back to drain pan 22.Therefore, because of causing the common electrode 31 of level sensor 30, this recirculation water after draining pump 12 shuts down, also is immersed in the discharge water, so electric current flows between this electrode with lower limit detecting electrode 32.
Like this; If draining pump 12 shuts down; The discharge water that then remains in the rising portions 19A of drainpipe 19 is back in the drain pan 22 because of deadweight, therefore, accumulates near the bottom surface of the 22A of portion even be arranged on draining to the suction inlet 12A of draining pump 12; Can not all discharge the discharge water in the drain pan 22, behind cooling operation, be in discharge water and accumulate in the state in the drain pan 22.If in drain pan 22, store discharge water for a long time, then might cause the assorted bacterium in this discharge water to breed and generation mucus, this mucus probably can be stopped up draining pump 12, drainpipe 19.
In this embodiment; In order to prevent to produce mucus; As shown in Figure 3; Accumulate the 22A of portion in the draining of drain pan 22, near below the level sensor 30, dispose silver (Ag) body 50 as metallic object, this silver body 50 contains the silver ion (Ag of the metal ion of the conduct regulation kind that possesses antibacterial action
+).
Usually, if in water, dispose silver-colored body 50, then on the surface of this silver body 50, because of the oxygen molecule (O in the water
2) oxidized and take place silver-ionizedly, this silver ion is diffused in the water.Yet, because silver is the less metal of ionization tendency, therefore only silver-colored body 50 is configured in the water, be difficult to generate the water that contains the silver ion that is useful on the enough concentration (for example 50ppm) that suppresses generation mucus at short notice.Therefore, through near below the level sensor 30, disposing silver-colored body 50, the part of the electric current that between the electrode of this level sensor 30, flows flows to silver-colored body 50, and the oxidation reactions on these silver body 50 surfaces are promoted, thereby a large amount of silver ions is diffused in the water.
Particularly, for example such at night, in the time that aircondition 1 stops, owing to do not generate new discharge water, so also do not have draining pump 12 runnings and make discharge water be discharged to the outer situation of machine.Therefore; At this stopping period, flow to silver-colored body 50 through a part that makes between the electrode of level sensor 30 electric current that flows since a large amount of silver ions from silver-colored body 50 strippings (stripping) to discharge water; Therefore, generate the water that contains the silver ion that is useful on the enough concentration that suppresses generation mucus.
The configuration structure of silver-colored body 50 then, is described.
If common electrode 31 is immersed in the discharge water with lower limit detecting electrode 32, then shown in the dotted line among Fig. 4, electric current flows to common electrode 31 along the streamline (streamline) of electric current 61 from lower limit detecting electrode 32.And in this Fig. 4, Reference numeral 62 expressions are located at common electrode 31 and lower limit detecting electrode 32 equipotential lines on every side.
Therefore, as shown in Figure 5 in this embodiment, disposing silver-colored body 50 between common electrode 31 and the lower limit detecting electrode 32 and near below this common electrode 31 and the lower limit detecting electrode 32.At this and since common electrode 31 and lower limit detecting electrode 32 after draining pump 12 shuts down also because of recirculation water is immersed in the discharge water, the time that therefore contact with discharge water is long, with the discharge water period of contact, electric current is mobile between this electrode via this discharge water.Therefore; Through silver-colored body 50 being configured between common electrode 31 and the lower limit detecting electrode 32 and near below this common electrode 31 and the lower limit detecting electrode 32; Because the part of the electric current that between these common electrodes 31 and lower limit detecting electrode 32, flows flows to silver-colored body 50 for a long time, therefore can seek to promote silver-ionized.And, if the lower end 32A of discharge water water table ratio lower limit detecting electrode 32 is lower, there is not electric current to flow owing between this electrode, reach silver-colored body 50, therefore should stop by the silver-ionized of silver body 50.Thus, when when drain pan 22 does not have water,, therefore can expect the long-life of silver-colored body 50 owing to silver-ionized being suppressed.
And silver-colored body 50 is disposed in draining and accumulates on the pedestal 51 of portion 22A bottom surface configuration so that from lower limit detecting electrode 32 to silver-colored body 50 apart from r1 with from this lower limit detecting electrode 32 to common electrode 31 roughly the same apart from r2.Silver-colored body 50 has the recess 51A that this silver body 50 embeds at this pedestal 51, so that can not move because of flowing of discharge water.
Thus; Owing to can the distance from lower limit detecting electrode 32 to silver-colored body 50 or common electrode 31 be kept approximate equality; Therefore, can make electric current approximate equality ground flow to silver-colored body 50 and common electrode 31, produce silver ion with antibacterial action from lower limit detecting electrode 32; And, can make draining pump 12 regular events.
In addition, this silver body 50 is big more with the contact area of water, oxidation reaction takes place more easily, thereby carry out silver-ionized more easily.Therefore, in this embodiment,, preferably rub into filamentary silver cotton-shaped and form silver-colored body 50 in order to seek to enlarge contact area.
Then, the reaction mechanism that generates silver ionized water is described.
Fig. 6 is the sketch map that is used to explain the reaction of electrode and silver-colored body.
If silver-colored body 50 is configured between common electrode 31 and the lower limit detecting electrode 32, through flow to the electric current of common electrode 31 from this lower limit detecting electrode 32, the surface of silver-colored body 50 is divided into anode portion 50A and negative pole part 50B.
So, the reaction of (1) takes place at the anode portion 50A of silver-colored body 50, the reaction of (2) takes place at negative pole part 50B, silver ion from the anode portion 50A stripping of silver-colored body 50 to discharge water.

Like this, at the anode portion 50A of silver-colored body 50, because therefore silver-colored body 50, is prevented on discharge water and drain pan 22, to produce mucus by silver-ionized and this silver ion is diffused in the discharge water.
The action of draining pump controlling organization 24 then, is described.
If the cooling operation of aircondition 1 begins, then compressor and indoor fan 7 entrys into service.When indoor fan 7 had begun running, it is on-stream that the fan running testing agency 26 of draining pump controlling organization 24 detects indoor fan 7, and speed setting mechanism 27 is set at maximum (top) speed with draining pump 12.
Draining pump controlling organization 24 is controlled the running of draining pump 12 based on the testing result of level sensor 30.That is, when the discharge water water level rose to the position of upper limit detecting electrode 33, draining pump controlling organization 24 made draining pump 12 runnings with the mode that draining pump driving mechanism 23 reaches maximum (top) speed.Through making draining pump 12 runnings, the discharge water that accumulates in the drain pan 22 is extracted and is discharged outside machine via drainpipe 19.
In addition, in the running of draining pump 12, if cooling operation stops, compressor and indoor fan 7 shut down, and then fan running testing agency 26 detects indoor fan 7 and shuts down.Because indoor fan 7 stops, speed setting mechanism 27 with the speed setting of draining pump driving mechanism 23 be can draining minimum speed, draining pump driving mechanism 23 moves draining pump 12 with this rotating speed.Like this; Through making draining pump 12, thereby make the noise such as underwater sound sound that stirs of draining pump 12 reach Min. with minimum speed running that can draining, and; After compressor and indoor fan 7 stopped, the discharge water that also will flow down and accumulate in attached to heat exchanger 16 grades in the drain pan 22 was discharged.
On the other hand, when the low position to lower limit detecting electrode 32 of discharge water water level, because draining pump 12 can not draining, therefore, draining pump controlling organization 24 stops draining pump driving mechanism 23, and stops the running of draining pump 12.
At this stopping period, because discharge water stores at drain pan 22, therefore, the part through the electric current that will between the electrode of level sensor 30, flow flows to silver-colored body 50, a large amount of silver ions from silver-colored body 50 strippings to discharge water.Thus, generate the water that contains the silver ion that is useful on the enough concentration that suppresses generation mucus.
At this moment, concentration of silver ions is high around silver-colored body 50, and it is low more to leave 50 of this silver bodies more.Therefore, preferably, seek the homogenising of concentration of silver ions through discharge water is moved.
Particularly, stop and being equivalent under the situation of time period in the late into the night (for example 0 o'clock to 5 o'clock) at aircondition 1, irrelevant with the testing result of level sensor 30, draining pump controlling organization 24 makes draining pump 12 actions, and extracts the discharge water in this drain pan 22.
At this moment, the discharge water of being extracted can not crossed the rising portions 19A of drainpipe 19 and discharged, and this water is back to drain pan 22 once more when draining pump 12 stops.Therefore, discharge water utilizes this recirculation water and is stirred, and silver ion spreads equably on drain pan 22.In this embodiment, draining pump controlling organization 24, draining pump driving mechanism 23 and draining pump 12 work as diffusion mechanism.
As stated; According to this embodiment; Because aircondition of the present invention has: heat exchanger 16, the drain pan 22 that receives the discharge water that flows down from this heat exchanger 16 and the draining pump 12 that extracts and discharge the discharge water that accumulates in this drain pan 22, and have the electric pole type level sensor 30 of the action that is used to control draining pump 12, configuration contains the silver-colored body 50 of the silver ion that possesses antibacterial action near the electrode of this level sensor 30; Therefore; Flow between this electrode and silver-colored body 50 through making via the part of discharge water at the electric current that flows between electrode, the stripping of silver ion in discharge water promoted that this silver ion is diffused in the discharge water.Therefore,, can suppress assorted bacterium and in discharge water, breed, and be suppressed at discharge water unvaryingly or drain pan 22 produces mucus through silver-colored body 50 being configured near the such simple structure electrode of level sensor 30.And, utilizing the running of draining pump 12, the discharge water with antibacterial action is discharged from, but because this discharge water through drainpipe 19, produces mucus so also can be suppressed at unvaryingly in this drainpipe 19.Thus, can realize the non-maintaining of drain pan 22.
Thereby, in the aircondition of this embodiment, owing to reduce the fault of drainage system; Safeguard easily; And carry out the purification of air-conditioning machine intimate, therefore, the present invention is to realizing that more comfortable air conditioning has contribution; Particularly, it is effective being arranged in the building that not specific much human such as school, hospital, convenience store gather.
And in this embodiment, common electrode 31 is long with the time that lower limit detecting electrode 32 contacts with discharge water, with the discharge water period of contact, electric current flows between this electrode via this discharge water.Therefore; Through silver-colored body 50 being configured in the below of common electrode 31 and lower limit detecting electrode 32; Because the part of the electric current that between these common electrodes 31 and lower limit detecting electrode 32, flows flows to silver-colored body 50 for a long time, therefore, can seek to promote silver-ionized.
And, according to this embodiment, because silver-colored body 50 is configured in like upper/lower positions; Promptly should silver body 50 and lower limit detecting electrode 32 between apart from the position roughly the same between r1 and this lower limit detecting electrode 32 and the common electrode 31 apart from r2; Therefore, can make electric current approximate equality ground flow to silver-colored body 50 and common electrode 31, can produce silver ion with antibacterial action from lower limit detecting electrode 32; And, make draining pump 12 regular events.
More than, an embodiment of the present invention is illustrated, but the present invention is not limited to this embodiment.For example, in this embodiment, adopted the structure that disposes silver-colored body 50 as metallic object, still,, also can adopt the structure of configuration copper (Cu) body, zinc (Zn) body so long as have the metallic object of antibacterial action.At this, known silver ion and copper ion (Cu
2+) compare and have about 40 times antibacterial action, with zinc ion (Zn
2+) compare and have about 10000 times antibacterial action.Therefore, it is more effective the structure of silver-colored body to be set.
And, in this embodiment, adopted the structure of utilizing level sensor 30 always to implement water level detecting, still, also can adopt every structure of implementing this water level detecting at a distance from the stipulated time.According to this structure, can sensed water level and the stripping quantity of control silver ion, thus the long-life that can seek silver-colored body 50.
In addition; In this embodiment, explained silver-colored body 50 has been configured in the structure that common electrode 31 and lower limit detecting electrode 32 position intermediate are the high A position of the density of streamline 61 of electric current; But, as long as in the scope of the streamline 61 of electric current, can silver-colored body 50 be configured in any position.
