Below, described dustiness detection display body Y is elaborated.
Fig. 5 is the front view of dustiness detection display body Y, and Fig. 6 is the oblique view of dustiness detection display body Y.
This dustiness detection display body Y is arranged on the position, side of the described blow-off outlet 6 of indoor set body 4 as described above.As shown in Figures 3 and 4, the front display board 13 that is made of translucent sheet of front covers.
Dustiness detection display body Y across whole width ground dispose side by side a plurality of (4) show with the dustiness display part (dustiness demonstration means) 16 of LED 15 and with gas sensor (dustiness detection means) GS of one (right side) sidepieces of this dustiness display part 16 adjacent settings.
In addition, dustiness display part 16 is described, each LED 15 is configured in the position of comparing with the front of dustiness detection display body Y inside, and its peripheric surface constitutes the reflection face 18 of inclined expansion forwards from LED 15.Thus, if LED 15 is luminous, then LED light is reflected facial 18 expansions, and illuminates front display board 13.
But, compare the position that is positioned at more forward side with LED 15 a plurality of with other (3) LED 15 of one (left side) sidepiece of gas sensor GS opposition side.Therefore, the area of the reflection face 18 around this LED 15 is less than the area of the reflection face 18 around other the LED 15.Even the illumination of all LED 15 is identical, also only have a little less than the illumination of LED 15 illumination front display boards 13 of a sidepiece.
That is, the LED 15 of a sidepiece will be used as " operation display lamp ", and other a plurality of LED 15 will be used as " dustiness display lamp ".
As " dustiness display lamp ", if the dustiness that detects by gas sensor GS more than a reference value of regulation, then all LED 15 will be turned off the light.In a reference value of regulation, if be " greatly " (air pollution degree is large), then have a LED 15 illuminated.If dustiness be " in ", then have two LED 15 illuminated.
And, if dustiness is " little " (air pollution degree is little), then have three LED 15 illuminated.That is, the number of lighting a lamp of LED 15 is more, represents that then the cleanliness factor of air is higher.
Described gas sensor GS is cylindrical shape, for detecting the semiconductor gas sensor that airborne pollution level is the concentration of foul smell (gas).That is, apply voltage at the gas sensitive by heater heating, and the variation of the resistance of the gas sensitive that will contact with gas is exported the device that the variation of (voltage) is obtained as the two ends of the load resistance of the setting of connect with gas sensitive.
The base end part of gas sensor GS is the same with described LED 15, is placed on the printing control substrate to carry out actual load.Because the leading section of gas sensor GS is side-prominent to the front, so its side face is formed with the depressed part 19 of rectangular shape.A position at depressed part 19 arranges porose 19a, and opposed with gas sensor GS.
As dustiness detection display body Y, with respect to the reflection face 18 around the front face 20a, LED 15, around the gas sensor GS depressed part 19 and up and down facial 20b be provided with back part 20c.With respect to back part 20c, and front face 20a, reflection are facial 18, depressed part 19, be formed with blank part between the facial 20b up and down.
The upper facial 20b at position is provided with air stream hand-hole 22 above as described depressed part 19, and the lower position at the reflection face 18 of a sidepiece is provided with air outflow section 23 at this front face.Thereby air is directed into the blank part of dustiness detection display body Y from air stream hand-hole 22, and invades in the depressed part 19 and blanketing gas sensor GS from the hole section that is arranged on depressed part 19.
And, be directed into blank part from the hole section that is arranged on depressed part 19, and flow out to the outside of dustiness detection display body Y from air outflow section 23.As mentioned above, dustiness detection display body Y is installed on the sidepiece with blow-off outlet 6 adjacent settings, and is configured to separate with the ventilation road 9 that is communicated with suction inlet 5 and blow-off outlet 6 the standalone configuration body of (zoning).
As shown in Figure 3 and Figure 4, be installed in the position, side of blow-off outlet 6 and the dustiness detection display body Y that the front is covered by front display board 13, open when the movable platen 3b rotation that preamble illustrated.On dustiness detection display body Y and be formed with gap Q between the movable platen 3b, do not have obstruction when inner thereby flow into from air stream hand-hole 22 at room air.
And air stream 23 open underneath that also show body Y in pollution detection of portalling, so after movable platen 3b rotates are from being that flow out smoothly the outside of indoor set body 4 here to the outside of dustiness detection display body Y.
On the one hand, as shown in Figure 1, compare the more position of the suction inlet side ventilation road 9b connection of upstream side with the heat exchanger 10 on ventilation road 9, be equipped with electrostatically atomizing unit (electrostatic atomization means) M.In this electrostatically atomizing unit M, emit electrostatic spray discharge port 25 position opening above blow-off outlet 6 of electrostatic spray.
Fig. 8 is the structure chart of electrostatically atomizing unit M, and Fig. 9 A, Fig. 9 B are the key diagram that the effect of electrostatically atomizing unit M is shown, and Figure 10 is the figure that illustrates with respect to the position of the electrostatically atomizing unit M of filter installation frame 26 and electrostatic spray discharge port 25.
Electrostatically atomizing unit M is made of water generating unit (water generation means) 30, discharge part 40 and high voltage bringing device 50.
Electrostatically atomizing unit M is installed in the back side of filter unit installation frame 26, and electrostatic spray discharge port 25 be installed in filter unit installation frame 26 below.Also can't be in sight under the open state even electrostatically atomizing unit M and electrostatic spray discharge port 25 make the part of blow-off outlet 6 and dustiness detection display body Y be in rotating movable platen 3b.
And, the sensor kinds such as a plurality of temperature sensors are installed in the indoor set body 4, and send detection signal to control part K only shown in Figure 1.The upper setting signal of setting of remote controller (remote control panel processed) also is sent to control part K.Cross flow fan 11 electrical components such as grade that illustrated in the above are all from control part K(control device) reception control signal controls.
Below, the effect of air conditioner 1 is described.
Room air is inhaled in the indoor set body 4 from suction inlet 5, and is caught and remove dust by air cleaner F.Further, thus room air is directed into suction inlet side ventilation road 9a and carries out the heat exchange air that heat exchange becomes cold wind or hot blast etc. at heat exchanger 10.Heat exchange air blows out to indoor from blow-off outlet 6 through blow-off outlet side ventilation road 9b, thereby indoor by the condition of air conditioning to setting.
Meet some requirements, then control part K transmits control signal to electrostatically atomizing unit M.Cool off thus to Peltier's element 31 energisings, and to water generation board 33.The part of the air amount in the suction inlet side ventilation road 9b touches the outside of water generation board 33 and is cooled, thereby dew W can generate and be attached to the outside of water generation board 33 and the outside of protecgulum 34.
Dew W is directed into protecgulum 34, and owing to gravity drops onto on the spray point 41.Spray point 41 is applied high voltage by high voltage bringing device 50 and discharges, and discharge process is in the dew W that is attached to spray point 41.Thereby the electrostatic atomization phenomenon occurs dew W splits into the particle footpath at the electronegative particulate of picometre to nanosized, thereby generates electrostatic spray.
On the other hand, on blow-off outlet side ventilation road 9b, the air-supply by cross flow fan 11 is so that near the position of electrostatic spray discharge port 25 becomes negative pressure with respect to the pressure in the spraying discharge piping 44.The electrostatic spray that generates at discharge part 40 is attracted to blow-off outlet 6 sides via spraying discharge piping 44, and is discharged to blow-off outlet 6 from being arranged near blow-off outlet 6 electrostatic spray discharge ports 25.
Electrostatic spray is discharged to indoor along with flowing of the heat exchange air that blows out from blow-off outlet 6.Electrostatic spray generates the OH free radical with strong oxidability, therefore, capture hydrogen atom by the strong oxidability of this OH free radical from airborne organic matter, thereby the combination of decomposing organic matter is to purify.The OH radical reaction is high, finally becomes carbon dioxide and water.
In addition, owing to heat exchange air blows out from blow-off outlet 6, so the peripheral position of blow-off outlet 6 and blow-off outlet 6 will become negative pressure state.In dustiness detection display body Y because air stream portals and 23 opens the position that approaches very much from blow-off outlet 6, therefore be accompanied by flowing of the heat exchange air that blows out from blow-off outlet 6, air stream portal 23 and its peripheral position also can negative pressure.
The air stream hand-hole 22 that is arranged on dustiness detection display body Y is communicated to air stream by blank part and portals 23, thereby the room air (being the air of the front face side of indoor set body 2) around the air stream hand-hole 22 will be inhaled in the air stream hand-hole 22.And because air stream hand-hole 22 is positioned at the position that separates from blow-off outlet 6, the heat exchange air that therefore blows out from blow-off outlet 6 will can not flow into air stream hand-hole 22.
Pure room air is directed in the dustiness detection display body Y from air stream hand-hole 22, and is full of the depressed part 19 that gas sensor GS is installed.Gas sensor GS detects the pollution level of room air, and this detection signal is sent to control part K.The room air that is full of depressed part 19 is directed into air stream via the blank part that is formed on dustiness display part 16 the insides and portals 23.
Arriving the air stream heat exchange air that 23 room air blown out from blow-off outlet 6 that portals attracts and flows out from air stream hand-hole 23.And blow out to indoor with the heat exchange air that blows out from blow-off outlet 6.New room air flows into air stream hand-hole 22, and repeats as described above to use gas sensor GS to detect behind the dustiness from air stream 23 effects of flowing out of portalling.
Thus, in dustiness detection display body Y, to portal to the air stream of gas sensor GS guiding room air 22 is arranged on the position that separates with blow-off outlet 6, and the air stream that will be communicated with this air stream hand-hole 22 portals and 23 is arranged on the front of indoor set body 4 and near position blow-off outlet 6.
After the room air that imports from air stream hand-hole 22 detects pollution level by gas sensor GS, portal 23 through the part guidance that separates with the ventilation road 9 that is formed on indoor set body 4 to air stream, and to the outside outflow of indoor set body 4.
Thereby, for guiding the air stream hand-hole 22 of room air to be arranged on from suction inlet 5 to blow-off outlet outside the 6 ventilation roads 9 that are communicated with to gas sensor GS and passing through the induced draft generation of operation of air conditioner process to the Air Flow of gas sensor GS.Thereby can not be subject to the impact of Air Flow on the ventilation road 9 of air-conditioning effect, and can improve the detection sensitivity of gas sensor GS.
But the mode in the front of dustiness detection display body Y with switch arranges movable platen 3b, and so that operation when stopping for closing opening during the operation beginning.Particularly, be arranged on the air stream hand-hole 22 of dustiness detection display body Y and air stream and portal and 23 when operation stops, being closed by movable platen 3b, therefore, even the long-term intrusion that also can stop reliably dust out of service.
Can not adhere to and pile up dust at gas sensor GS, and can prevent the reduction of transducer sensitivity when the beginning of operation of air conditioner.
Gas sensor GS will be sent to control part K from the detection signal that room air detects, and judge pollution level here.And, transmit control signal from control part K to dustiness display part 16 so that when showing dustiness, transmit control signal to electrostatically atomizing unit M so that carry out above-mentioned operation, thereby carry out the cleaning of the heat exchange air that blows out from blow-off outlet 6.As a result, can the cleaningization room.
The control part K that has received control signal from gas sensor GS controls the demonstration of dustiness display part 16 according to pollution level, and related therewith electrostatically atomizing unit M is moved control.
Fig. 7 A, Fig. 7 B, Fig. 7 C, Fig. 7 D and Fig. 7 E are the figure of the expression example of explanation dustiness display part 16.
Shown in Fig. 7 A, in the front display board 13 on the surface that covers dustiness display part 16, has the operation explicit identification 60 that throws light on by the LED 15 that opens along with the beginning of operation of air conditioner at one (left side) sidepiece.Be provided with the gas sensor sign 70 that there is gas sensor GS in expression at another (right side) sidepiece.Rear side in this gas sensor sign 70 disposes gas sensor GS.
Have certain interval between operation explicit identification 60 and the gas sensor sign 70, and dispose 3 above-mentioned LED 15 in the rear side of this spatial joint clearance.By the unlatching of each LED 15, it is 80 illuminated that the dustiness that is arranged on front display board 13 identifies, thereby make resident family can confirm air pollution degree.
Control part K with the dustiness that gas sensor GS detects, is divided into the above judgement grade of at least 3 grades.In fact 4 grades shown in Fig. 7 B～Fig. 7 E, have been divided into.
Control part K judges that dustiness is that the 4th of greatest level is judged when grade is above, as " dustiness is more than 4 ", to all LED 15 of dustiness display part 16 no power all.That is, be " light-off ", be shown as all dustiness sign 80(Fig. 7 B that extinguish between operation explicit identification 60 and the gas sensor sign 70).
Control part K controls electrostatically atomizing unit M so that with all strength continuously operation simultaneously.Thereby promote the acceleration cleaningization in room.
Judge that dustiness be that next better-than-average level is namely less than the 4th judging grade, when the 3rd judgement grade is above, as " dustiness 3 ", a LED 15 of dustiness display part 16 being switched on.That is, be by " 1 lamp ", near a LED 15 control that is unlocked of operation explicit identification 60, the dustiness of its appropriate section identifies 80 illuminated (Fig. 7 C).
Simultaneously control part K controls electrostatically atomizing unit M so that take continuous operating time as 2, dwell time carries out intermittent duty as 1 ratio, thereby promotes the cleaning in room.
Judge that dustiness be that again below average level is namely less than the 3rd judging grade, when the second judgement grade is above, as " dustiness 2 ", two LED 15 of dustiness display part 16 being switched on.That is, be by " 2 lamp ", near two LED 15 control that is unlocked of operation explicit identification 60, the dustiness of its appropriate section identifies 80 illuminated (Fig. 7 D).
Control part K controls electrostatically atomizing unit M simultaneously, so that the in the same manner intermittent duty of continuous operating time and dwell time, thereby keep the cleaning in room.
Judge that dustiness be that again little grade (pollution level is minimum) grade is namely less than second judging grade, when the first judgement grade is above, as " dustiness 1 ", whole LED 15 of dustiness display part 16 being switched on.That is, for " all lamps ", all LED 15 are opened control, thereby (Fig. 7 E) all opened in the illumination of dustiness sign 80.
Simultaneously control part K controls electrostatically atomizing unit M, so that take continuous operating time as 1, dwell time is that 2 ratio is carried out intermittent duty, thereby the cleaningization that prevents the room is destroyed.
Like this, can when suitably keeping the air cleaning ability, make electrostatically atomizing unit M long-lived.
In addition, in the time of the beginning operation of air conditioner, when beginning by gas sensor GS detection dustiness, gas sensor GS need to be initialized control.That is, control so that sensor does not detect when beginning at the appointed time, wait stable the beginning afterwards to measure.
What at this moment control part K was provisional controls dustiness display part 16, so that show that dustiness is middle degree, for example, is shown as dustiness " 3 ".Simultaneously electrostatically atomizing unit M is controlled so that take continuous operating time as 2, dwell time carries out stroboscopic motion as 1 ratio.
Thus, even in the initialization procedure of gas sensor GS, also can carry out by electrostatically atomizing unit M the cleaning of room air, in fact can shorten the time of room air cleaningization.
And, might appear at that gas sensor GS breaks down in the operation of air conditioner, thus the situation of air pollution degree in can not sensing chamber.
When this fault occured, control part K can suppose corresponding to the duration of operation of air conditioner the dustiness of room air, and the operation of control electrostatically atomizing unit M.Thereby, not only can keep the cleanliness factor in room, and the rough sledding to resident family can be suppressed to Min..
Although described the part embodiment, these embodiments only present as an example, are not limited to scope of the present utility model.In fact, new embodiment described herein can show as other various forms; In addition, can in the situation that not break away from the utility model spirit, embodiment described herein be carried out various omissions, substitute and change.Appending claims and equivalency range thereof comprise described various forms or the improvement that falls in the scope and spirit of the present utility model.
According to the utility model, select not to be subjected to the impact of the Air Flow that operation of air conditioner follows, stably produce the Air Flow position and carry out dustiness and detect, thereby can improve accuracy of detection.
