As depicted in figs. 1 and 2, indoor set main body 2 have front suction entrance 2a and above suction inlet 2b as the suction inlet that sucks room air, but front suction entrance 2a has the movable front panel (hereinafter being called simply front panel) 4 of freely openable, when air conditioner stops, front panel 4 is closed front suction entrance 2a with main body 2 driving fits, on the other hand, and when air-conditioner operation, move with the direction that main body 2 deviates from front panel 4 edges, opens front suction entrance 2a.

Inside in main body 2 possesses: be arranged on front suction entrance 2a and above the prefilter 5 that be used for to remove the dust that air contains in downstream of suction inlet 2b; Be arranged on prefilter 5 the downstream be used for from front suction inlet 2a and above the room air that sucks of the suction inlet 2b heat exchanger 6 that carries out heat exchange; For delivery of carried out the indoor fan 8 of the air of heat exchange at heat exchanger 6; The air that switching will blow from indoor fan 8 is to the indoor blow-off outlet that blows out 10 and change up and down the blade up and down 12 of Air blowing direction; Left and right blade 14 with ground, left and right change Air blowing direction.In addition, the top of front panel 4 is connected with the top of main body 2 by a plurality of arms (not shown) that are arranged on its both ends, by driving control with a plurality of arms in a drive motors that is connected (not shown), when air-conditioner operation, the position when front panel 4 stops from air conditioner (occlusion locations of front suction entrance 2a) forwards moves.Similarly up and down blade 12 also is connected with the bottom of main body 2 by a plurality of arms (not shown) that are arranged on its both ends.

(structure of electrostatic atomization apparatus)

In addition, in the end of a side of indoor set (from the front of indoor set in left end, the back is with bypass flow path 22 sides of partition wall 46c of narration) be provided with for the scavenger fan unit 16 that room air is taken a breath, 16 rear is provided with the electrostatic atomization apparatus 18 with the air-cleaning function that produces the static mist and purify the air of a room in the scavenger fan unit.

In addition, Fig. 1 expresses the state after the body cover (not shown) that covers front panel 4 and main body 2 is removed, and Fig. 2 expresses the state that the electrostatic atomization apparatus 18 that will be housed in main body 2 inside for the link position of clear and definite indoor set main body 2 and electrostatic atomization apparatus 18 separates with main body 2.Electrostatic atomization apparatus 18 is actual is presented on the shape shown in Fig. 3, as Fig. 1 or shown in Figure 4, is arranged on the left side of main body 2.

as extremely shown in Figure 4 in Fig. 2, from front suction inlet 2a and above suction inlet 2b via heat exchanger 6, indoor fan 8 grades are communicated in the primary flow path 20 of blow-off outlet 10, be provided with electrostatic atomization apparatus 18 in the way with the bypass flow path 22 of heat exchanger 6 and indoor fan 8 bypass (walking around), be provided with high-tension transformer 24 and bypass blowing fan 26 as high voltage source at the upstream side of bypass flow path 22, be provided with electrostatically atomizing unit 30 and silencing means 32 in the downstream of bypass flow path 22, this electrostatically atomizing unit 30 has the radiating part 28 of the heat radiation that promotes electrostatically atomizing unit 30.Therefore, to dispose successively the state of high-tension transformer 24, bypass blowing fan 26, radiating part 28, electrostatically atomizing unit 30 and silencing means 32 from upstream side, be housed in the housing 34 of a part that consists of bypass flow path 22.By being housed in like this in housing 34, can improve assembling, owing to having formed stream with housing 34, therefore saved the space, and based on the air stream of bypass blowing fan 26 can be reliably with heating part be that high-tension transformer 24 and radiating part 28 are touched and it is cooling mutually, and the static mist that produces from electrostatically atomizing unit 30 can be imported reliably the blow-off outlet 10 of air conditioner, can be to by the static mist that indoor release produced of air-conditioning.

In addition, housing 34 is according to the front from indoor set main body 2, make the direction mode parallel with respect to the direction of the air stream that flows through primary flow path 20 of the air stream that flows through housing 34 inside, longitudinally configuration, can in the position disposed adjacent overlapping with scavenger fan unit 16, further save the space from the front of indoor set main body 2 thus.

In addition, high-tension transformer 24 not necessarily will be housed in housing 34, but for the ventilation that utilizes bypass flow path carry out cooling, suppress temperature rise or save the space this on the one hand, preferably be housed in housing 34.

At this, with reference to Fig. 5 and Fig. 6, existing known electrostatically atomizing unit 30 is described.

As shown in Figure 5, electrostatically atomizing unit 30 is by consisting of with lower component: a plurality of Peltier elements 36 with radiating surface 36a and cooling surface 36b; The above-mentioned radiating part (for example radiating fin) 28 that is connected with the hot driving fit of radiating surface 36a ground; At the sparking electrode 38 of cooling surface 36b by electrically insulating material (not shown) the vertical setting in hot driving fit ground; The comparative electrode 40 that only separates predetermined distance with relative this sparking electrode 38 and configure.

In addition, as shown in Figure 6, the control part 42 (with reference to Fig. 1) of configuration is electrically connected with Peltier driving power 44 and high-tension transformer 24 near scavenger fan unit 16, and Peltier element 36 is electrically connected to Peltier driving power 44 and high-tension transformer 24 respectively with sparking electrode 38.

In addition, to produce the static mist as electrostatically atomizing unit 30 in order making from sparking electrode 38 electrions, also comparative electrode 40 can not to be set.For example, if a terminal of high voltage source is connected with sparking electrode 38, another terminal is connected with framework, can discharge between the part of the close sparking electrode 38 of the structure that is connected to framework and sparking electrode 38.In this structure, the structure that this can be connected to framework is regarded comparative electrode 40 as.

In the electrostatically atomizing unit 30 of said structure, control Peltier driving powers 44 in Peltier element 36 during current flowing by control part 42, heat moves to radiating surface 36a from cooling surface 36b, because sparking electrode 38 temperature reduce on sparking electrode 38 dewfall.In addition, control high-tension transformer 24 by control part 42, when applying high voltage to the sparking electrode 38 that is attached with dew, can electric discharge phenomena occur in dew and produce the static mist that particle diameter is nano-scale.In addition, in the present embodiment, owing to using negative high voltage power source as high-tension transformer 24, so static fog belt negative electricity.

in addition, in the present embodiment, as shown in Figure 7, primary flow path 20 is by the rear wall 46a of the stand 46 that consists of main body 2, the two side of forwards extending from the both ends of this rear wall 46a (only having expressed left side wall Fig. 7) 46b, the rear wall 48a of the rear guide part (air-supply guide part) 48 that forms below stand 46, form with the two side of forwards extending from the both ends of this rear wall 48a (only expressing left side wall Fig. 7) 48b, consist of by a sidewall (left side wall) 46b of stand 46 and a sidewall (left side wall) 48b of rear guide part 48 the partition wall 46c that bypass flow path 22 is separated from primary flow path 20.In addition, form the bypass suction inlet 22a of bypass flow path 22 at a sidewall 46b of stand 46, on the other hand, form the bypass blow-off outlet 22b of bypass flow path 22 at a sidewall 48b of rear guide part 48.

When air conditioner refrigeration, the relative humidity of the Cryogenic air of the heat exchanger 6 by indoor set is high, when in the situation that possess in electrostatic atomization apparatus 18 be used to the Peltier element 36 that keeps the skin wet, be easy to not only at the pin-shaped sparking electrode 38 of Peltier element 36 but also produce dewfall at whole Peltier element 36.On the other hand, when air conditioner heats, because the relative humidity of the high temperature air by heat exchanger 6 is low, therefore at the sparking electrode 38 of Peltier element 36, the possibility of dewfall does not occur very high.

Therefore according to said structure, by with partition wall 46c, primary flow path 20 being separated with bypass flow path 22, and the electrostatic atomization apparatus 18 that produces the static mist is set in bypass flow path 22, can not supply with to electrostatic atomization apparatus 18 thus and do not carry out by heat exchanger 6 air that humiture is adjusted.Thus, can effectively prevent from producing dewfall at the whole Peltier element 36 of electrostatically atomizing unit 30 when refrigeration, improve security.In addition, can produce reliably the static mist when heating.

Bypass flow path 22 is made of bypass suction line 22c, housing 34 and bypass discharge pipe 22d, the bypass suction line 22c that one end is connected with the bypass suction inlet 22a that is formed at stand sidewall 46b to left (with left side wall 46b roughly quadrature, with the direction of front panel 4 almost parallels) extend, the other end is connected with an end of housing 34, and extend downwards then to right-hand warpage with bypass discharge pipe 22d that the other end of housing 34 is connected with an end, its other end is connected with the bypass blow-off outlet 22b of a sidewall 48b of rear guide part 48.Like this by consist of the part of bypass flow path 22 with housing 34, therefore realized the saving space, and can 20 attract reliably the static mist from electrostatically atomizing unit 18 to primary flow path by bypass discharge pipe 22d by this a series of structure, thereby can be to by the indoor release electrostatic mist of air-conditioning.

Bypass suction inlet 22a between prefilter 5 and heat exchanger 6, namely be positioned at the downstream of prefilter 5 and the upstream side of heat exchanger 6, due to utilize prefilter 5 can effectively remove from front suction inlet 2a and above the dust that contains the air that sucks of suction inlet 2b, therefore can suppress dust and invade electrostatic atomization apparatus 18.Thus, can effectively prevent dust accretions at electrostatically atomizing unit 30, and release electrostatic mist stably.

In such embodiment, constitute the prefilter that doubles as electrostatic atomization apparatus 18 and primary flow path 20 with prefilter 5, only prefilter 5 is cleaned thus and safeguard just passablely, owing to not needing to carry out each other maintenance, so can simplify maintenance.

On the one hand, bypass blow-off outlet 22b be positioned at heat exchanger 6 and indoor fan 8 downstream blow-off outlet 10 near, constitute the static mist that spues from bypass blow-off outlet 22b and be full of whole room along with the air stream diffusion of primary flow path 20.Such a bypass blow-off outlet 22b is configured in the downstream of heat exchanger 6, because if when being configured in the upstream side of heat exchanger 6, because heat exchanger 6 is metal, can be absorbed into heat exchanger 6 as the major part (about more than 8～9 one-tenth) of the static mist of charged particle.In addition, bypass blow-off outlet 22b is configured in the downstream of indoor fan 8, because if when being configured in the upstream side of indoor fan 8, because can there be turbulent flow in the inside of indoor fan 8, the air of the inside by indoor fan 8 with process that each position of indoor fan 8 bumps in the part (about about 5 one-tenth) of static mist can be absorbed.

In addition, primary flow path 20 sides at a sidewall 48b of the rear guide part 48 that is provided with bypass blow-off outlet 22b, by utilizing indoor fan 8 to make air stream have the speed of regulation, primary flow path 20 sides and bypass flow path 22 sides at sidewall 48b produce pressure reduction, make with respect to bypass flow path 22, primary flow path 20 1 sides become the negative pressure section of relatively low pressure, thereby 20 attract air from bypass flow path 22 to primary flow path.Therefore, bypass blowing fan 26 can have low capacity, also bypass blowing fan 26 can be set according to circumstances.

In addition, bypass discharge pipe 22d with the junction of two streams (bypass blow-off outlet 22b) of primary flow path 20 point to respect to the air stream in primary flow path 20 roughly the mode of the direction of quadrature be connected with partition wall 46c (the sidewall 48b of rear guide part 48).This is to produce the static mist because electrostatically atomizing unit 30 utilizes electric discharge phenomena as above, therefore must follow discharge sound, and discharge sound (discharge sound) has directive property.Therefore, locate in bypass flow path 22 and the junction of two streams (bypass blow-off outlet 22b) of primary flow path 20, discharge sound is pointed to be in indoor set the place ahead or the oblique people in the place ahead by bypass flow path 22 and front panel 4 almost parallel ground being connected, can constituting, thereby reduced noise.

In addition, as shown in Figure 8, bypass discharge pipe 22d is connected with respect to partition wall 46c with the junction of two streams place of primary flow path 20 obliquely at it, when connecting in the mode with respect to the air stream directed upstream side in primary flow path 20, has the effect that further reduces the noise that causes due to discharge sound.

In addition, even in the situation that the pointing direction of bypass discharge pipe 22d points to the downstream direction of the air stream in primary flow path 20 and connects, its extended line is so long as not stretching out to the outside from blow-off outlet 10, the discharge sound that produces directly passes from blow-off outlet 10 can be less to the amount of outside, because the sound that directly enters user's ear is also less, therefore can obtain to reduce the effect of noise.

as mentioned above, owing to partition wall 46c, primary flow path 20 being separated with bypass flow path 22, the electrostatic atomization apparatus 18 that produces the static mist is arranged on the bypass flow path 22 that heat exchanger 6 bypass are communicated with primary flow path 20, thereby do not supply with to electrostatic atomization apparatus 18 and do not carry out by heat exchanger 6 air that humiture is adjusted, therefore can effectively prevent from the whole Peltier element 36 of electrostatically atomizing unit 30, dewfall occuring when refrigeration, improved security, and can produce reliably the static mist when the heating operation, can with the operation mode of air conditioner irrespectively, namely with irrespectively stably produce the static mist season.

In addition, the installment state of the electrostatic atomization apparatus 18 when Fig. 9 represents indoor set main body 2 from the side, electrostatic atomization apparatus 18 is the shape corresponding with the back space of scavenger fan unit 16, and is accommodated in this space.

Figure 10 expresses the electrostatic atomization apparatus 18A with housing 34, and this electrostatic atomization apparatus 18A is arranged in indoor set main body 2 as shown in figure 11.Perhaps, be arranged in dashed region 18B shown in Figure 11 (being in roughly the same position with electrostatically atomizing unit 30 and the silencing means 32 in the downstream that is arranged on bypass flow path 22 in electrostatic atomization apparatus shown in Figure 9 18).With electrostatic atomization apparatus 18A be arranged on from the positive of indoor set or above see the position overlapping with scavenger fan unit 16, and make electrostatic atomization apparatus 18A be arranged on the peristome 62 of scavenger fan unit 16 and air door 64 near, thereby make it be disposed at the part that the air that attracted by scavenger fan unit 16 flows through.

Be described in further detail, the electrostatic atomization apparatus 18A of Figure 10 installs electrostatically atomizing unit 30 and silencing means 32 with radiating part 28 integratedly, do not comprise that electrostatically atomizing unit 30 parts of radiating part 28 and silencing means 32 are housed in separately housing (unit housings 66 and silencing means housing 68), silencing means housing 68 is connected and is communicated with the end of bypass discharge pipe 22d, and the other end of bypass discharge pipe 22d is connected and is communicated with primary flow path 20.In this case, that separate from primary flow path 20 by partition wall 46c and and the left surface of not shown body cover between form and resettlement section 22e that dispose scavenger fan unit 16, electrostatic atomization apparatus 18A etc., become the parts that substitute described bypass suction line 22c and housing 34, and also accommodate bypass discharge pipe 22d, consist of as bypass flow path 22.

In addition, bypass discharge pipe 22d narrates at preamble by the method that the direction of pointing to respect to the air stream of primary flow path 20 seeks to reduce noise, but also can as required needn't be like this, and silencing means housing 68 also can directly connect with bypass blow-off outlet 22b.Thus, can make the structure of electrostatic atomization apparatus 18A simpler.But, need consider direction the same as bypass discharge pipe 22d in order to reduce noise.

Thus, suck the interior air of main body 2 from the bypass suction inlet 22a suction resettlement section 22e in the downstream of prefilter 5 by prefilter 5, when seeing indoor set main body 2 from the front, the direction of this air stream flows in the 22e of resettlement section abreast with respect to the direction of the air stream that flows through primary flow path 20.By the air that flows in the 22e of resettlement section like this can cooling heat dissipation section 28, and enter electrostatically atomizing unit 30 by the peristome (not shown) in unit housings 66 formation.

According to such structure, from the positive of indoor set or above see that the surrounding space with overlapping scavenger fan unit 16, scavenger fan unit 16 becomes bypass flow path 22, thereby can effectively utilize the resettlement section 22e of scavenger fan unit 16, electrostatic atomization apparatus 18A etc., realize saving the space.In addition, for this structure, high-tension transformer 24 can be configured in any part in the resettlement section 22e of scavenger fan unit 16, electrostatic atomization apparatus 18A etc., and bypass blowing fan 26 is not set.

In addition, this bypass flow path 22, air stream consists of with respect to the mode that the air stream by primary flow path 20 flows abreast when seeing indoor set main body 2 from the front, can use the so simple structure of partition wall 46c with primary flow path 20 and bypass flow path 22 branches according to the mode of above describing in detail thus, therefore bypass flow path 22 can be easily formed, number of components can be reduced.

In addition, by this structure, can make the prefilter of electrostatic atomization apparatus 18A and the prefilter of primary flow path 20 share prefilter 5.Because the effect that shares has been described in the front, omitted detailed description at this.

In addition, also can form opening 46d near the bottom of the stand 46 at the rear portion that is positioned at scavenger fan unit 16, in order to draw the pipe arrangement (not shown) that connects indoor set and off-premises station.Above-mentioned bypass suction inlet 22a is an opening for the resettlement section 22e that forms with air intake resettlement section 22e and at partition wall 46c (stand sidewall 46b), outside by prefilter 5 and indoor set is communicated with, but the opening 46d that forms in the bottom of stand 46, the outside of resettlement section 22e and indoor set directly is communicated with, and becomes the opening that sucks surrounding air.In this case, resettlement section 22e becomes and makes the also bypass flow path of bypass of prefilter 5.Therefore, the air that is drawn into electrostatic atomization apparatus 18A flows into and does not pass through prefilter 5 from opening 46d, therefore also the prefilter that electrostatic atomization apparatus 18A uses can be set in addition as required.In addition, as long as in the structure that is formed with opening 46d, from the positive of indoor set or above, electrostatic atomization apparatus 18A is arranged on the overlapping this formation in position in scavenger fan unit 16 does not change, just resettlement section 22e can be effectively utilized, the space can be realized saving equally.

As mentioned above, because primary flow path 20 sides of bypass blow-off outlet 22b make air stream have the speed of regulation by indoor fan 8, thereby produce pressure reduction and become the negative pressure section that is attracted, even therefore bypass blowing fan 26 is not set, also can utilize the air cooling heat dissipation section 28 from attracting to primary flow path 20 as the resettlement section 22e of bypass flow path by bypass discharge pipe 22d, will utilize the static mist that produces of electrostatically atomizing unit 30 attract primary flow path 20, and be discharged into indoor by air-conditioning.In addition, if as dashed region 18B near peristome 62 and air door 64, radiating part 28 is configured in the part that the air that is drawn into peristome 62 flows through, thereby also can is undertaken cooling by the air that is attracted by scavenger fan unit 16.

In addition, as shown in figure 11, due to the radiating part 28 of electrostatic atomization apparatus 18A with 16 peristomes 62 that arrange approach and configure in the scavenger fan unit, therefore can by the further cooling heat dissipation of the air that is drawn into peristome 62 section 28, promote the heat radiation from electrostatically atomizing unit 30.In addition, in the situation that the fan that use is exclusively used in ventilation is as scavenger fan unit 16, due to air door (damper) 64 not being set, so can make radiating part 28 and the suction inlet of scavenger fan unit 16 approach configuration, cooling heat dissipation section 28 so effectively.

as mentioned above, according to said structure, owing to partition wall 46c, primary flow path 20 being separated with the resettlement section 22e that becomes bypass flow path, and the electrostatic atomization apparatus 18A that will produce the static mist is arranged in the 22e of resettlement section, and do not supply with to electrostatic atomization apparatus 18A and do not carry out by heat exchanger 6 air that humiture is adjusted, therefore can effectively prevent from producing dewfall and improving security at the whole Peltier element 36 of electrostatically atomizing unit 30 when refrigeration, and can produce reliably the static mist when the heating operation, with the operation mode of air conditioner irrespectively, namely with irrespectively stably produce the static mist season.

(running of electrostatic atomization apparatus is controlled)

This is controlled by setting a plurality of parameters as the running permissive condition of electrostatic atomization apparatus 18,18A, only in the situation that all parameters all represent the running license of electrostatic atomization apparatus 18,18A, allow electrostatic atomization apparatus 18,18A running, on the other hand, in the situation that at least one parameter does not represent the license of turning round, forbid electrostatic atomization apparatus 18,18A running, thereby paste the viewpoint in the service life of element 36 from energy-conservation or amber ear, prevent the unnecessary running of electrostatic atomization apparatus 18,18A, and prevent abnormal running.

In the present embodiment, as the running permissive condition, be set with following parameter.

(i) situation of the temperature and humidity of room air in the running adimission area of electrostatic atomization apparatus 18,18A

(ii) rotating speed of indoor fan 8 is the above situation of regulation rotating speed

(iii) electrostatic atomization apparatus 18, the normal situation of 18A

At first, the running adimission area of the electrostatic atomization apparatus 18 of above-mentioned (i), 18A described.

in indoor set, the inlet temperature sensor 92 (with reference to Figure 13) that detects the temperature of the air suck be arranged at suction inlet (front suction entrance 2a or top suction inlet 2b) near, the humidity sensor 94 (with reference to Figure 13) that detects the humidity of the air that sucks is arranged at for example power supply board of indoor set, temperature and humidity based on the air that sucks indoor set is set electrostatic atomization apparatus 18, the running adimission area of 18A, in humidity that the temperature and moisture sensors 94 that inlet temperature sensor 92 detects detects in the situation that in this running adimission area, allow electrostatic atomization apparatus 18, the 18A running, on the other hand, in the temperature and humidity that detects in the situation that the running adimission area outside, forbid electrostatic atomization apparatus 18, the 18A running.

According to said structure, do not need the cold-boundary temperature determinator, simple in structure, can not cause that cost rises, in the temperature and humidity that detects in the situation that the running adimission area outside, forbid electrostatic atomization apparatus 18,18A running, thus can be with the preventing trouble before it happens of abnormal sound and ozone, and can realize the long lifetime of electrostatic atomization apparatus or energy-conservation.

Describe with reference to the curve of Figure 12 running adimission area to electrostatic atomization apparatus 18,18A.As shown in figure 12, based on the temperature and humidity of the air that sucks indoor set, sets superfluous dewfall zone, the first performance exterior domain and freezing point lower area, set zone beyond this Three regions as the adimission area of turning round.Superfluous dewfall zone is zone as described below: because of humidity high (more than the first setting), and shorten at the water of sparking electrode 38 dewfall and the distance of comparative electrode 40, and become state near short circuit, the abnormal sound due to short circuit current does not perhaps produce the static mist with desirable particle diameter.In addition, the first performance exterior domain be humidity low (below the second little setting of above-mentioned the first setting) even and the amber ear paste the zone that element 36 performance maximum capacities do not reach dew-point temperature yet, owing to not being discharge between dew and comparative electrode 40, but therefore the discharge between sparking electrode 38 and comparative electrode 40 may produce ozone.In addition, the freezing point lower area is that the dew-point temperature obtained according to the wet air chart is in zone below freezing.

Namely, by setting superfluous dewfall zone and forbidding the running of electrostatic atomization apparatus 18,18A, can prevent from causing abnormal sound or causing not producing the static mist with desirable particle diameter along with indoor humidity increases and shortens in the distance of the water of the superfluous dewfall of high-voltage electrode and comparative electrode.

In addition, by setting the first performance exterior domain and forbidding the running of electrostatic atomization apparatus 18,18A, even can prevent that the low amber ear of indoor humidity from pasting element performance maximum capacity and also not reaching dew-point temperature and cause producing ozone.

In addition, by setting the freezing point lower area and forbidding the running of electrostatic atomization apparatus 18,18A, even can prevent from also carrying out unnecessary action in the zone of dew-point temperature under freezing point, cause shorten the service life of electrostatic atomization apparatus 18,18A, maybe can not realize energy-conservation.

In addition, be provided with ceiling temperature in the curve map of Figure 12, but the zone more than this ceiling temperature depends on the size of radiating part 28, so this zone can be called the second performance exterior domain.Namely, as mentioned above, when when the amber ear pastes element 36 by electric current, heat moves to radiating surface 36a from cooling surface 36b, the temperature of sparking electrode 38 reduces, and thus in sparking electrode 38 dewfall, the heat that moves to radiating surface 36a dispels the heat from radiating part 28, but this puts from the taking in property of electrostatically atomizing unit 30, and the size of radiating part 28 is restricted.The size of radiating part 28 considers that the highest design temperature when warming operation (for example at least, 30 ℃) under regular event and setting reliably, with electrostatically atomizing unit 30 at this at temperature more than the highest design temperature (for example 32～35 ℃) also roughly normally the mode of action set.But, when reaching this highest design temperature when above, along with temperature raises, hinder the possibility of regular event also to increase.Therefore, during the highest design temperature when detected temperatures surpasses warming operation as ceiling temperature, be considered as hindering the second performance exterior domain of the regular event of electrostatically atomizing unit 30.In addition, when cooling operation, the size of radiating part 28 is equally also restricted, and for example, the ceiling temperature that indoor temperature is reduced to here is that below 30 ℃, then electrostatic atomization apparatus 18,18A just can move.

That is, by setting the second performance exterior domain, can prevent from causing over ceiling temperature making electrostatic atomization apparatus 18,18A running under the action unsure state of amber ear subsides element 36.

Then, the rotating speed of the indoor fan 8 of above-mentioned (ii) described.

The cooling surface 36b that pastes element 36 from the amber ear dispels the heat by radiating part 28 to the heat that radiating surface 36a moves, but at the not enough regulation rotating speed of the rotating speed of the indoor fan 8 that is detected by speed detector 96 (with reference to Figure 13) (for example, about 400rpm) in situation, the heat radiation of radiating part 28 is insufficient, can not paste the element 36 desirable cooling performances of performance by the amber ear.Therefore, at the rotating speed of indoor fan 8 in the situation that more than the regulation rotating speed, allow electrostatic atomization apparatus 18,18A running, on the other hand, in the situation that deficiency regulation rotating speed is forbidden electrostatic atomization apparatus 18,18A running.

Thus, the action that both can prevent from pasting because of the deficiency amber ear that dispels the heat element 36 is unstable, can prevent from again bringing into play that the amber ear pastes the cooling performance of element 36 and the dew that can not get stipulating at sparking electrode 38 and produce ozone.In addition, when the rotating speed of indoor fan 8 hanged down, the discharge sound of electrostatic atomization apparatus 18,18A was sometimes more remarkable, in the situation that deficiency regulation rotating speed stops by the running with electrostatic atomization apparatus 18,18A, can avoid the generation of this noise.

in addition, electrostatic atomization apparatus 18 as above-mentioned (iii), 18A's is abnormal, set the fault (output voltage abnormal) of high voltage transformer 24 and the fault that the amber ear pastes driving power 44 (output voltage extremely), by comprising electrostatic atomization apparatus 18, the control part 42 (with reference to Figure 13) of the abnormal detector of 18A does not detect in the situation of fault that high voltage transformer 24 or amber ear paste driving power 44, allow electrostatic atomization apparatus 18, the 18A running, on the other hand, cause when abnormal when fault because of any one party being detected, forbid electrostatic atomization apparatus 18, the 18A running.Thus, can prevent that electrostatic atomization apparatus 18,18A from turning round existing under abnormal state.

Figure 13 means the block diagram of signal transmitting and receiving of the control part 42 of the control part 72 of indoor set and electrostatic atomization apparatus 18,18A.

As shown in figure 13, the output of the output of the output of inlet temperature sensor 92, humidity sensor 94 and speed detector 96 is imported into the control part 72 of indoor set, and the control part 42 of electrostatic atomization apparatus 18,18A monitors the output valve of high voltage transformers 24 and the output valve that Po Er pastes driving power 44.At this, inlet temperature sensor 92 and humidity sensor 94 use the sensor that uses in the control of the freeze cycle when the operation of air conditioner of refrigeration and heating or dehumidifying.

the control part 72 of indoor set, the humidity that the temperature and moisture sensors 94 that only detects at inlet temperature sensor 92 detects is at electrostatic atomization apparatus 18, in the running adimission area of 18A, and the rotating speed of the indoor fan 8 that speed detector 96 detects is more than the regulation rotating speed, and from electrostatic atomization apparatus 18, the abnormal signal of the control part 42 of 18A is not input in the situation of control part 72, to electrostatic atomization apparatus 18, the control part 42 output running enabling signals of 18A, electrostatic atomization apparatus 18, the control part 42 of 18A receives the running enabling signal, control high voltage transformer 24 and Po Er and paste driving power 44.

On the other hand, in humidity that the temperature and moisture sensors 94 that inlet temperature sensor 92 detects detects in the situation that outside the running adimission area of electrostatic atomization apparatus 18,18A or the not enough regulation rotating speed of rotating speed of the indoor fan 8 that detects of speed detector 96 or be input to the control part 72 of indoor set from the abnormal signal of the control part 42 of electrostatic atomization apparatus 18,18A, not from control part 72 to electrostatic atomization apparatus 18, the control part 42 output running enabling signals of 18A, forbid electrostatic atomization apparatus 18,18A running.

In addition, in the block diagram of Figure 13, the control part 42 output running enabling signals from the control part 72 of indoor set to electrostatic atomization apparatus 18,18A, but also can replace turning round enabling signal and the signal of out-put supply ON.

According to above-mentioned structure, do not need to measure the cold-boundary temperature determinator etc. of temperature that the amber ear pastes the cooling surface of element, simple in structure, inlet temperature sensor 92 and humidity sensor 94 can be also used as the checkout gear that also uses in the running operation of air conditioner in addition of electrostatic atomization apparatus 18,18A, can prevent that cost from rising.

In addition, set the parameter of above-mentioned (i)～(iii) as the running permissive condition of electrostatic atomization apparatus 18,18A, but also can be on the basis of these parameters, calculated the power consumption of electrostatic atomization apparatus 18,18A indoor set in addition by control part 72, in the situation that allow below power value, allow electrostatic atomization apparatus 18,18A running, on the other hand in the power consumption of calculating, when surpassing when allowing power value, forbid electrostatic atomization apparatus 18,18A running.

Below, be described in more detail with reference to table 1 pair this parameter.

(table 1)

An example of the power consumption of table 1 expression indoor set, when the allowance power consumption of supposing indoor set is 18W, and when the stable state consumed power of establishing microcomputer (control part 72) etc. is 10W, need to use remaining 8W, make electrostatic atomization apparatus 18,18A, up and down blade 12 and left and right blade 14 or other drive division parallel running.Therefore, be set as and destatic beyond atomising device 18,18A, the aggregate value of the power consumption that calculates be the allowance power value (for example, 14W) in following situation, allow electrostatic atomization apparatus 18,18A running, on the other hand, when surpassing the allowance power value, forbid electrostatic atomization apparatus 18,18A running.By said structure, can prevent from surpassing the allowance power of indoor set.

Then, to the human body detection device of the position of detecting the people is set in indoor set main body 2, the air-conditioning control of carrying out based on the people's who is detected by human body detection device position describes.

In addition, with reference to Figure 23 to only be used to whether to have in the first to the 3rd sensor 126,128,130 output determinating area A, B, C the people situation describe.

As shown in figure 23, in the cycle T 1 before being right after time t1, in the situation that the first to the 3rd sensor 126,128,130 OFF (no pulse) all, when time t1, be judged to be in regional A, B, C nobody at (A=0, B=0, C=0).Then, during the time t2 after 1 from time t1 to cycle T, in the situation that only have first sensor 126 output ON signals (pulse is arranged), the second and the 3rd sensor 128,130 to be OFF, when time t2, being judged to be has nobody in people, regional B, C (A=1, B=0, C=0) in regional A.In addition, during the time t3 after 1 from time t2 to cycle T, in the situation that the first and the 3rd sensor 126,130 is exported the ON signals, the second sensor 128 is OFF, when time t3, being judged to be has nobody in people, regional A, B (A=0, B=0, C=1) in regional C.Below same, each cycle T 1 is all judged in each regional A, B, C whether have the people to exist.

In fact, use the first to the 5th sensor 126,128,130,132,134, carry out which zone judgement whether someone deposits in regional A～I, table 5 expression use from all sensors 126,128,130,132,134 output judge whether have in each regional A～I the people result of determination.

(table 5)

In addition, in table 5, the location determination matching step S1 of table 2 to the location determination shown in table 4, the result of determination separately of S3, S5 are carried out.

Based on this result of determination, each regional A～I is judged to be: often have the people first area (Place for people is often arranged), short second area of time of people (zone that the people only passes through, the zone that the holdup time is short etc. are by the zone) is arranged, people's very short the 3rd zone (the non-life that the people such as wall, window go hardly is regional) of time is arranged.Below, first area, second area, the 3rd zone are called life zoning I, life zoning II, life zoning III, and life zoning I, life zoning II, life zoning III also can be called the zone of region characteristic I, the zone of region characteristic II, the zone of region characteristic III.In addition, also can be with life zoning I (region characteristic I), life zoning II (region characteristic II) in the lump as life zone (zone of people's life), on the other hand, the zoning of living III (region characteristic III) is as non-life zone (people is or not the zone of this life), according to whether have the people frequency rough classification is carried out in the zone of life.

This differentiation is carried out later at the step S7 of the flow chart of Figure 21, with reference to Figure 24 and Figure 25, this method of discrimination is described.

Figure 24 is illustrated in the situation that the indoor set of air conditioner of the present invention is set in the LD of the 1LDK that is made of a bedroom, LD (parlor hold concurrently dining room) and kitchen, and the region representation experimenter shown in the ellipse of Figure 24 declares often Place for people.

As mentioned above, all judge in each regional A～I whether have the people to exist in each cycle T 1, reaction result (judgement) output 1 (responding) or 0 (reactionless) as cycle T 1, with this judgement return multiple carry out repeatedly after, in step S7, determine whether through the accumulated running time of air conditioner of regulation.When being judged to be in step S7 when not passing through the stipulated time, get back to step S1, on the other hand, when being judged to be when having passed through the stipulated time, reaction result and 2 threshold values of accumulative total within this stipulated time of each regional A～I are compared, thus each regional A～I is differentiated respectively in the zoning I～III that lives any one.

With reference to Figure 25, long-term accumulated result is described in more detail, set first threshold and the Second Threshold less than first threshold, in step S8, whether the long-term accumulated result of judging each regional A～I is more than first threshold, is judged to be the zone of Duoing than first threshold and differentiates in step S9 and be life zoning I.In addition, in step S8, when the long-term accumulated result that is judged to be each regional A～I is lacked than first threshold, in step S10, whether the long-term accumulated result of judging each regional A～I is more than Second Threshold, be judged to be the zone of Duoing than Second Threshold and differentiate in step S11 and be life zoning II, on the other hand, be judged to be the zone of lacking than Second Threshold and differentiate in step S12 and be the zoning III that lives.

In the example of Figure 25, regional E, F, I be by the differentiation zoning I alive that makes a living, and regional B, H be by the differentiation zoning II alive that makes a living, and regional A, C, D, G are by the differentiation zoning III alive that makes a living.

In addition, Figure 26 is illustrated in the situation that the indoor set of air conditioner of the present invention is set in the LD of another LDK, and Figure 27 represents the result as the basis, each regional A～I differentiated take long-term accumulated result in this case.In the example of Figure 26, regional C, E, G be by the differentiation zoning I alive that makes a living, and regional A, B, D, H be by the differentiation zoning II alive that makes a living, and regional F, I are by the differentiation zoning III alive that makes a living.

In addition, the differentiation of above-mentioned region characteristic (life zoning) is all returned multiple carrying out in per stipulated time, but only otherwise the mobile indoor sofa that will differentiate, the dining table etc. of being disposed at are differentiated result almost constant.

Then, with reference to the flow chart of Figure 22 to whether have in each regional A～I the people final decision describe.

The flow chart of step S21～S26 and above-mentioned Figure 21 step S1～S6 is identical, therefore the description thereof will be omitted.In step S27, determine whether and (for example obtained stipulated number M, 15 times) the reaction result of cycle T 1, when being judged to be cycle T 1 and not reaching stipulated number M, get back to step S21, on the other hand, when being judged to be cycle T 1 and having reached stipulated number M, in step S28, with the number of times between the accumulative total stage of reaction that adds up to of the reaction result of cycle T 1 * M, and the accumulative total that calculates once amount number of times between the stage of reaction.With this accumulative total between the stage of reaction calculating of number of times return multiple repeatedly, in step S29, (for example, the result of calculation of accumulative total number of times between stage of reaction N=4) is when being judged to be when not reaching stipulated number to determine whether the stipulated number amount that obtained, get back to step S21, on the other hand, when being judged to be when having reached stipulated number, in step S30, whether according to the accumulative total of the region characteristic of having differentiated and stipulated number amount number of times between the stage of reaction, inferring in each regional A～I has the people to exist.

In addition, in step S31, deduct 1 from the calculation times (N) that adds up number of times between the stage of reaction, get back to step S21, repeat thus the calculating of accumulative total number of times between the stage of reaction of stipulated number amount.

The up-to-date once amount of table 6 expression (resume of the reaction result of time T 1 * M), in table 6, for example, the accumulative total of once amount that the ∑ A0 meaning refers to regional A number of times between the stage of reaction.

(table 6)

At this, if the accumulative total that is right after the once amount before ∑ A0 between the stage of reaction number of times be ∑ A1, if its again before once the amount accumulative total between the stage of reaction number of times be ∑ A2 ... in the situation that N=4, with regard to life zoning I, even in the resume (∑ A4, ∑ A3, ∑ A2, ∑ A1) of past 4 times amount, once above accumulative total between the stage of reaction number of times be 1 time, be judged to be the people.In addition, with regard to life zoning II, even in the past resume of 4 times, once above accumulative total between the stage of reaction number of times be more than 2 times, be judged to be the people, and with regard to life zoning III, if in the past in the resume of 4 times, the above accumulative total of secondary between the stage of reaction number of times be more than 3 times, be judged to be the people.

Then, from above-mentioned people after elapsed time T1 * M no judgement, equally according to the resume of past 4 amounts, life zoning and number of times between the accumulative total stage of reaction, carry out the people in no inferring.

namely, in the indoor set of air conditioner of the present invention, use is inferred the people no than the sensor of the quantity that the quantity of critical region A～I is lacked, therefore in the inferring of every specified period, might judge people's position by accident, whether therefore avoid no matter people's position deduction is carried out in the overlapping region in specified period individually, by the region characteristic that adds up for a long time according to the regional determination result with every specified period to obtain, and the resume in accumulative total past of number of times between the stage of reaction in each zone that the regional determination result accumulative total of every specified period of N amount the is obtained location of inferring the people, can obtain the high people's of probability position deduction result.

Table 7 expression so judge the people no and be set as T1=5 second, inferring the needed time, not inferring the needed time in M=12 situation.

(table 7)

The life zoning	Inferring	Do not inferring
			I	60 seconds (soon)	240 seconds (slowly)
II	120 seconds (standard)	180 seconds (standard)
			III	180 seconds (slowly)	120 seconds (soon)

Like this, after the area region of utilizing the first to the 5th sensor 126,128,130,132,134 will utilize the indoor set of air conditioner of the present invention will carry out air-conditioning divides a plurality of regional A～I into, determine region characteristic (the life zoning I～III) of each regional A～I, according to the region characteristic of each regional A～I, change is being inferred the needed time, is not being inferred the needed time again.

Namely, due to after having changed the air-conditioning setting, until arriving, wind needs about 1 minute, even therefore the short time (for example, several seconds) in, the change air-conditioning is set and also to be impaired comfortableness, moreover, and for people moment not the place, from energy-conservation viewpoint, preferably often do not carry out air-conditioning.Therefore, at first detect in each regional A～I the people no, then will have especially the air-conditioning in people's zone to set optimization.

Specifically, zone take differentiation as life zoning II infer the needed time as standard no, in the zone of differentiating for life zoning I, the existence of inferring the people with the regional short time interval that than differentiation is life zoning II, on the other hand, in the situation that the people left should the zone, the long time interval of zone that to use than differentiation be life zoning II is inferred not existing of people, to be set as shortlyer inferring the needed time thus, will be not be set as longer inferring the needed time.On the contrary, in the zone of differentiating for life zoning III, the existence of inferring the people with the long time interval of zone that than differentiation is life zoning II, on the other hand, in the situation that the people left should the zone, infer not existing of people with the regional short time interval that than differentiation is life zoning II, will be set as longlyer inferring the needed time thus, the general be set as shorter inferring the needed time.In addition, as mentioned above, the life zoning in each zone changes according to long-term accumulated result, accordingly, is inferring the needed time and is not also carrying out variable setting inferring the needed time.

(wind direction control)

In addition, set according to the air-conditioning of each regional A～I, carry out the rotating speed control of indoor fan 8 and the wind direction of up and down blade 12 and left and right blade 14 and control, below, these controls are described.

Control wind direction before the heel of wind direction control by the people in the zone that is judged to be people during heating, warm braw is arrived near pin, the wind direction during refrigeration is controlled by the overhead to the people and is controlled wind direction, makes cold wind arrival overhead.Wind direction is regulated according to the rotating speed of indoor fan 8 and the angle of up and down blade 12 or left and right blade 14.

Figure 28 represents the rotation control of up and down blade 12, and when air conditioner stopped, as shown in (a), front panel 4, up and down blade 12 and left and right blade 14 were in totally enclosed state.

When refrigeration, in order to make blow out air (cold wind) to intelligent's overhead (during refrigeration, being the ceiling air-flow), from the state shown in (a), through the state shown in (b), arrive the state shown in (c).At first, drive control arm 118,120, front panel 4 leaves front suction entrance 2a, drives simultaneously control arm 122,124, and up and down blade 12 leaves blow-off outlet 10.

Under the state of (c), the air that blows out from blow-off outlet 10 passes through up and down blade 12 guiding horizontal directions, but crooked upward because of the end of downstream side of up and down blade 12, therefore air can be delivered to the distant place in room.At this moment, the top of blow-off outlet 10 be the below of front panel 4 by Leaf 114 sealing, the part of the air that blows out from blow-off outlet 10 can not import front suction entrance 2a.

On the other hand, when heating, in order to make blow out air (warm braw) to (during heating, being the underfooting air-flow) near intelligent's pin, from the state shown in (a), through the state shown in (b), arrive the state shown in (d).Under the state of (d), the air that blows out from blow-off outlet 10 is by the oblique below of up and down blade 12 guiding, but crooked to main body side because of the end of downstream side of up and down blade 12, therefore the warm air that easily is stranded in the top in room can be delivered to the below in room.

In addition, when (e) being used for stable front refrigeration, blow out air is towards human body (towards the air-flow of human body).

The setting rotating speed of the indoor fan 8 when Figure 29 represents to carry out the air-conditioning of each regional A～I, A1, A2, A3 be respectively be arranged in apart from indoor set closely, distance, the remote reference rotation speed in zone, the speed discrepancy that A4 far causes for the zone of distance when identical for example, carries out respectively following setting.

A1:800rpm (during heating), 700rpm (during refrigeration)

A2:1000rpm (during heating), 900rpm (during refrigeration)

A3:1200rpm (during heating), 1100rpm (during refrigeration)

A4:100rpm (changes in temperature share)

At this, as the distance apart from indoor set in each zone of expression, apart from the expression with the position relationship of indoor set such as the angle in indoor set front, difference of height, import this expression of relative position.

In addition, in each zone, utilize the air-conditioning requirement degree to represent the degree of easily carrying out air-conditioning, being difficult to carry out air-conditioning, the air-conditioning requirement degree is higher, more is difficult to carry out air-conditioning, and the air-conditioning requirement degree is lower, more easily carries out air-conditioning.For example, far away apart from the distance of indoor set, blow out air more is difficult to arrive, and more be difficult to carry out air-conditioning, so the air-conditioning requirement degree is higher.That is, the air-conditioning requirement degree with apart from the relative position of indoor set, close relevance is arranged, in the present embodiment, according to the relative position of distance indoor set, determine the air-conditioning requirement degree.

Therefore, the setting rotating speed of the indoor fan 8 when meaning the air-conditioning that carries out each regional A～I is set as higher rotating speed when the air-conditioning requirement degree is higher.Namely, want the position in zone of air-conditioning far away apart from indoor set, the setting speed setting of indoor fan 8 is higher rotating speed, and in the situation that the distance of distance indoor set is identical, more be partial to the zone of left and right from the front of indoor set, the setting speed setting of indoor fan 8 is higher rotating speed.In addition, be one in the situation that want the zone of air-conditioning, be set as the setting rotating speed (air quantity) in this zone, be a plurality of in the situation that want the zone of air-conditioning, be set as the setting rotating speed in the high zone of air-conditioning requirement degree.

In addition, blade up and down 12 when Figure 30 represents to heat and the set angle of left and right blade 14, B1, B2, B3 be respectively be arranged in apart from indoor set closely, distance, the remote benchmark up and down blade angle in zone, the differential seat angle of the blade up and down that B4 far causes for the zone of distance when identical, on the other hand, C1 and C2 are the benchmark left and right blade angle (turning left to be positive direction) in zone, left and right, and C3 and C4 are the differential seat angle of the regional left and right blade 14 that far causes, for example, carry out respectively following setting.In addition, the angle of up and down blade 12 refers to, under the state that blade raises up, the line of establishing the front and back end that connects blade is to be 0 ° in the situation of level, take this position as benchmark, and the angle during instrumentation in the counterclockwise direction.

B1：70°

B2：55°

B3：45°

B4：10°

C1：0°

C2：15°

C3：30°

C4：45°

Namely, in the situation that near the regional A of indoor set or the heating of B, up and down blade 12 (for example is set as the first angle, 70 °), and the speed setting of indoor fan 8 be the first rotating speed (for example, 800rpm), control wind direction to the edge part (before people's heel) of the indoor pusher side of regional A or B, warm braw is arrived near pin.In addition, in the situation that be arranged in apart from the heating of regional C, D, E or the F of indoor set distance, up and down blade 12 than little the second angle of the first angle (for example is set as, 55 °), and the speed setting of indoor fan 8 than high the second rotating speed of the first rotating speed (for example is, 1000rpm), control wind direction to the edge part (before people's heel) of the indoor pusher side of regional C, D, E or F, warm braw is arrived near pin.In addition, in the situation that carry out apart from indoor set farthest regional G, H or the heating of I, up and down blade 12 than the little third angle degree of the second angle (for example is set as, 45 °), and the speed setting of indoor fan 8 than high the 3rd rotating speed of the second rotating speed (for example is, 1200rpm), control wind direction to the edge part (before people's heel) of the indoor pusher side of regional G, H or I, warm braw is arrived near pin.

In addition, Figure 31 represents to rise or the blade up and down 12 the during refrigeration of unstable region and the set angle of left and right blade 14, E1, E2, E3 be respectively be arranged in apart from indoor set closely, distance, the remote benchmark up and down blade angle in zone, the differential seat angle of the blade up and down that E4 far causes for the zone of distance when identical, on the other hand, F1 and F2 are the benchmark left and right blade angle (turning left to be positive direction) in zone, left and right, F3 and F4 are the differential seat angle of the regional left and right blade 14 that far causes, for example, carry out respectively following setting.In addition, the state the when running refer to air conditioner of rising begins, unstable region refers to that current indoor air-conditioning state does not reach the state of the condition of setting (for example, design temperature).

E1：50°

E2：35°

E3：25°

E4：10°

F1：0°

F2：15°

F3：25°

F4：35°

In addition, blade up and down 12 when Figure 32 represents the refrigeration of stability region and the set angle of left and right blade 14, benchmark when H1 is the ceiling air-flow is blade angle up and down, benchmark when H2 is escape air-flow up and down blade angle, H3 are the differential seat angle of the blade up and down that causes of distance, on the other hand, I1 and I2 are the benchmark left and right blade angle (turning left to be positive direction) in zone, left and right, I3 and I4 for example, carry out respectively following setting for the differential seat angle of the regional left and right blade 14 that far causes.In addition, the stability region refers to that current indoor air-conditioning state has reached the state of the condition (for example, design temperature) that sets.

H1：180°

H2：190°

H3：5°

I1：0°

I2：15°

I3：25°

I4：35°

At this, as shown in Figure 28 (c), the ceiling air-flow is as downstream: make up and down blade 12 be positioned at the bottom of blow-off outlet 10, the concave surface reception by blade blows out wind fully, and wind is sent the air-flow that forms.The escape air-flow is as downstream: compare during with the ceiling air-flow make the up and down blade 12 be positioned at the slightly upper, make a part (trace) that blows out wind also flow to the convex side (below of blade) of blade, formation is difficult to occur the state of dewfall on the blade convex surface, and wind is sent the air-flow that forms.

In the situation that near the regional A of indoor set or the refrigeration of B, up and down blade 12 is set as from level and (for example only tilts predetermined angular downwards, 5 °), the speed setting of indoor fan 8 is the first rotating speed (rotating speed that lacks for the first rotating speed than when heating, for example, 700rpm), set according to the fallen mode of overhead and cold air shape spray ground that makes cold wind arrive regional A or B.In addition, in the situation that be arranged in apart from the refrigeration of regional C, D, E or the F of indoor set distance, up and down blade 12 is set as approximate horizontal, the speed setting of indoor fan 8 is second rotating speed higher than the first rotating speed (rotating speed that the second rotating speed for than heating the time lacks, for example, 900rpm), set according to the mode that makes cold wind arrive the overhead of regional C, D, E or F.In addition, in the situation that carry out apart from indoor set farthest regional G, H or the refrigeration of I, up and down blade 12 is set as from level and (for example tilts upward predetermined angular, 5 °), the speed setting of indoor fan 8 is three rotating speed higher than the second rotating speed (rotating speed that the 3rd rotating speed for than heating the time lacks, for example, 1100rpm), set according to the mode that makes cold wind arrive the overhead of regional G, H or I.

Then, the flow chart with reference to Figure 33 describes the wind direction control of carrying out according to the quantity of wanting the zone of air-conditioning.

After operation of air conditioner begins, in step S41, at first carry out the people of regional A～I in no judgement, be that the zone that namely will carry out air-conditioning is one in the situation that be judged to be people's zone in step S42, in step S43, carry out air-conditioning based on air quantity, the wind direction set according to this zone.When being judged to be the zone that to carry out air-conditioning not being one in step S42, in step S44, judge whether the zone that will carry out air-conditioning is two, is two in the situation that will carry out the zone of air-conditioning, moves to step S45.

In step S45, air quantity is set as the setting air quantity in the high zone of air-conditioning requirement degree, as shown in Figure 34 A～Figure 34 E, the configuration mode of Two Areas is identified as any one in five patterns, in next step S46, according to the pattern of identifying, as shown in table 8 control.

(table 8)

At this, pattern 1 expression distance is for middle distance and clip the situation of the positive adjacent Two Areas of indoor set, and the angle of pattern 2 expressions and indoor set is situation consistent and adjacent Two Areas on context roughly.Mode 3 represents and the angle of the indoor set situation of the consistent and Two Areas that separates on context roughly in addition.The distance of pattern 4 expression and indoor set roughly unanimously and the situation of the different Two Areas of angle.The Two Areas that pattern 5 expression separates, the also situation of different Two Areas of and angle different from the distance of indoor set in other words.

The wind direction up and down of pattern 1～4 is fixed in requirement degree low zone in when heating, on the other hand, is fixed in requirement degree high zone when refrigeration.In addition, the wind direction up and down of pattern 5 is by controlling the action of up and down blade 12, be repeated below action: the first area in Two Areas (the first and second zones) stops the stipulated time (angle is fixed) afterwards, change wind direction to second area, after second area stops the stipulated time, change wind direction to the first area.In addition, each regional time of staying is for example set respectively according to the distance of distance indoor set, preferably more extends the time of staying apart from the distance of indoor set is more far away.

In addition, the left and right wind direction of pattern 1 is fixed in the central authorities of adjacent Two Areas, in the situation that pattern 2 and 3, Two Areas is considered as being positioned at the roughly different position of unidirectional distance when indoor set is seen, its left and right wind direction is fixed in requirement degree high zone.In addition, the action of left and right blade 14 is similarly controlled in the left and right wind direction of the pattern 5 that pattern 4 and configuration by the Two Areas that separates consist of and the control of up and down blade 12, be repeated below action: after the first area stops the stipulated time, change wind direction to second area, after second area stops the stipulated time, change wind direction to the first area.In addition, each regional time of staying respectively according to for each zone apart from the relative position of indoor set, for example set apart from the angle in indoor set front, preferably the angle apart from the indoor set front is larger, more extends the time of staying.

In addition, when being judged to be the zone that will carry out air-conditioning not being two in step S44, in step S47, the zone more than three that will carry out air-conditioning is judged to be any pattern in two patterns such as normal mode and special pattern according to its configuration.At this, special pattern represents distance for middle distance and clips the adjacent Two Areas in the front of indoor set and distance amounts to trizonal situation for a zone remote and that be positioned at the indoor set front, and the information slip in the zone more than three in addition is shown normal mode.Be more than three in the situation that will carry out the zone of air-conditioning, air quantity is set as the setting air quantity in the highest zone of air-conditioning requirement degree, when being judged to be the special pattern shown in Figure 35 A (central authorities are adjacent) in step S47, in step S48, wind direction is set as with the pattern 1 of Figure 34 A same.

On the other hand, when being judged to be in step S47 when not being special pattern, in step S49, carry out the control of the normal mode shown in Figure 35 B or Figure 35 C, the up and down wind direction near the set angle of the blade up and down 12 in the zone of indoor set, and change between the set angle away from the blade up and down 12 in the zone of indoor set.

In addition, the left and right wind direction during normal mode is: the zone at two ends (in Figure 35 B, is regional C and I; In Figure 35 C, be regional C and H; ) the set angle of left and right blade 14 be set as left end angle and right-hand member angle, and be repeated below action: after the left end angle stops the stipulated time, distolateral area change wind direction (waving) to the right, after the right-hand member angle stops the stipulated time, to the area change wind direction (waving) of left end side.The responsiveness of the left and right blade 14 when waving in addition, is set as slower than the responsiveness of the left and right blade 14 of above-mentioned pattern 4 and 5.In addition, the time of staying of left end angle or right-hand member angle, for example set respectively according to the angle in distance indoor set front, preferably the angle apart from the indoor set front is larger, more extends the time of staying.

In addition, carried out air-conditioning control separately in step S43, S46, S48 or S49 after, get back to step S41.

(skin nursing and room nursing are controlled)

At this, about with the use human body detection device (sensor unit 126,128,130,132,134) of above-mentioned explanation thus wind direction control the method for more effectively applying flexibly the static mist with electrostatic atomization apparatus 18,18A combination and describe.As mentioned above, the static mist not only has the deodorizing effect of removing the foul smell composition, also has the effect of improving skin quality.This improves the skin quality effect and refers to, if the static mist arrives occupant's skin, although there is individual differences, bring moist can for people's skin.

In the present embodiment, to work as the people and set the skin nursing pattern take the effect that performance improves people's skin quality as the control that the static mist occurs main purpose when indoor, with the people not indoor, namely not the time be set as the room NM to bring into play indoor deodorizing effect as the control that the static mist occurs main purpose.In addition, in the situation that the static mist that occurs under the skin nursing pattern and indoor foul smell composition react, the performance deodorizing effect.

The air conditioner of present embodiment possesses indoor set, this indoor set have detect the people at no human body detection sensor as human body detection device (sensor unit 126,128,130,132,134) with electrostatic atomization apparatus 18, the 18A of static mist occur, the control of above-mentioned air conditioner is provided with two patterns such as room NM that skin nursing pattern that the people carries out and people do not carry out when indoor when indoor.That is, be judged to be in the detection range of human body detection sensor in the situation that there is the people in the zone of stipulating, be set as the skin nursing pattern, carry out wind direction to the direction in the zone of this regulation and control, the people who the static mist is arrived detect is the zone of this regulation maybe; In the situation that be judged to be nobody in the detection range of human body detection sensor, be set as the room NM, make the static mist arrive the zone in top or a distant place.In addition, the above-mentioned wind direction that illustrated control when coordinating heating and the indoor temperature during refrigeration and indoor human feeling to temperature control, but the static mist both can coordinate changes in temperature to turn round to occur, and also can coordinate the air-supply that has stopped freeze cycle turning round to occur.

By this structure, in the skin nursing pattern, can bring moist to Person's skin by the static mist.In addition, in the room NM, due to the people not indoor, blow out air-flow facing to the misgivings of human body etc. so need not to consider to make, can spread all over the ceiling of top and room around whole and efficiently and effectively the foul smell composition that is attached to wall and curtain etc. is carried out deodorizing or degerming, can realize comfortable indoor environment.

Below, direction and the method regional and that critically control that at length detects people's existence by human body detection sensor described.

In the skin nursing pattern that the people carries out when indoor, set according to the air-conditioning of each regional A～I, controlling with above-mentioned wind direction the rotating speed that similarly carries out indoor fan 8 controls and the wind direction control of blade 12 and left and right blade 14 up and down, when heating, control wind direction before the heel of people in the zone that is judged to be the people, and when refrigeration, wind direction is controlled to be the top that makes blow out air (cold wind) arrive the zone that is judged to be the people.Simultaneously, make electrostatic atomization apparatus 18,18A action, make static mist that electrostatic atomization apparatus 18,18A occur and warm braw or cold wind together arrive the occupant, carry out skin nursing.

In addition, in the skin nursing pattern, can not also to carry out wind direction to control to the zone that is judged to be the people, but control and the wind direction of up and down blade 12 and left and right blade 14 is controlled with the rotating speed that the mode that the static mist arrives frequency that the people is arranged high zone (zone of region characteristic I) is carried out indoor fan 8.

On the other hand, the people not the time room NM that carries out in, at first smelly in order to remove adhering to of wall surface and curtain or floor and ceiling, make indoor fan 8 and electrostatic atomization apparatus 18,18A action, as Figure 29 and shown in Figure 32, at the appointed time arrive this regional mode with the ceiling air-flow that carries out in when refrigeration by the order of regional A, B, C, F, G, H, I according to the static mist and control up and down blade 12 and left and right blade 14.

Reason is that regional A, B, C, F, G, H, I are the zone that is positioned at the outside in 9 zones dividing, far away apart from indoor set, suppose that these zones have wall and curtain.In addition, blow to the ceiling air-flow of top by employing, also can make the static mist arrive estimate to be attached with the ceiling of the foul smell of tobacco etc., and the static mist that flows along ceiling by the ceiling air-flow bumps with wall surface and flows to the below, so also can carry out deodorizing and the degerming on floor.

At this, regional A, B be positioned at indoor set the face that arranges (wall surface) near, therefore can not carry out fully this deodorizing that face is set, degerming with the ceiling air-flow.Therefore, also can replace the wind direction of Figure 32 to control, as shown in figure 36, and the angle of setting up and down blade 12 and left and right blade 14 is carried out wind direction control.

Then, consider above-mentioned region characteristic I, II, III, carry out the control of indoor fan 8, up and down blade 12 and left and right blade 14.That is, the zone of region characteristic I is the high zone of frequency that the people is arranged, and people's frequency is arranged by the order reduction of region characteristic I → II → III.Therefore, from frequency that the people is arranged high zone, carry out successively the control of indoor fan 8, up and down blade 12 and left and right blade 14, make the static mist arrive successively at the appointed time the zone of region characteristic I～III.In addition, there is people's frequency high zone to adhere to odorous possibility high, the stipulated time that therefore by the order increase of region characteristic III → II → I, the static mist is arrived.Control by carrying out like this wind direction, even be attached with foul smell, also can remove.

On the contrary, the high zone of someone frequency is in the skin nursing pattern that the people carries out when indoor, also can think and the static mist by Enough supply, therefore also can be from the frequency that the people is arranged low zone, carry out successively the control of indoor fan 8, up and down blade 12 and left and right blade 14, make the static mist arrive successively at the appointed time the zone of region characteristic I～III.In addition, there is people's frequency low zone also can think in the skin nursing pattern and do not remove fully foul smell, the stipulated time that therefore the static mist is arrived.Control by carrying out like this wind direction, also can remove and fully do not removed and remaining foul smell.

Perhaps, the device that is carried out accumulative total the time that is judged to be the people in the skin nursing pattern can be set also, according to the time by this integrating device accumulative total, the time that change static mist arrives.That is, think that the cumulative time is longer, foul smell more has residual, and therefore in the room NM, the official hour that arrives by extending the static mist can further improve deodorizing effect or bacteria-eliminating efficacy.

In addition, in the example of Figure 29, it is 1200rpm that the maximum of the indoor fan 8 during air-conditioning is set rotating speed, but due to the people not the time do not need to consider noise etc. fully, therefore also can be as shown in figure 37, add the air drag of flow direction changer (up and down blade 12 and left and right blade 14), set the rotating speed of indoor fan 8, improve the attainability of static mist.

L1：1200rpm

L2：1300rpm

L3：1400rpm

At this moment, when further make 16 actions of scavenger fan unit with indoor air exhaust when outdoor, can promote the purification of room air.

In addition, any one detects the people and enters when indoor in by the first to the 5th sensor 126,128,130,132,134 in the way that the nursing of skin nursing and room is controlled, set according to the air-conditioning in the zone that detects, return to above-mentioned " controlling " of the wind direction control of the rotating speed control, up and down blade 12 and the left and right blade 14 that carry out indoor fan 8 when the chamber.

In addition, the people not situation in can considering running at air conditioner temporary transient not situation and air-conditioning is stopped and situation about withdrawing from etc.On-stream temporary transient not in the situation that, the changes in temperature running also can along with directly not beginning the room NM in time-lag, as energy-saving operation described later, also can be carried out the room NM.In the situation that do not exist because withdrawing from, also can under the air-supply running, carry out the room NM of stipulated time.

(do not detecting Energy Saving Control and preventing forgetting shutdown and control)

Be provided with timer at indoor set, use this timer to carry out not detecting Energy Saving Control and the anti-control of forgetting to shut down as economizing electric operation.Below, do not describe at detection Energy Saving Control and the anti-method of controlling of forgetting to shut down carrying out with the form of room NM.

Figure 38 represent the people indoor and people not when indoor air quantity (rotating speed) by control room internal fan 8 and the ability that is arranged at the compressor of off-premises station realize economizing the example of electric operation.

That is, when increasing the air quantity of indoor fan 8, the heat exchanger effectiveness of heat exchanger 6 improves, in the situation that the frequency of compressor is identical, refrigeration or heating capacity increase, therefore for indoor temperature being remained identical design temperature, can reduce the frequency of compressor, necessary consumed power reduces.In addition, when the people not the time, the air quantity of indoor fan 8 can not produce unplessantness displeasure that air-flow causes excessively by force yet and the noise of indoor fan 8 increases the problems such as comfortableness that cause even increase.And can make static mist spread all over each corner in room by producing simultaneously the static mist and blowing out this moment, can be set as the room NM and carry out deodorizing and sterilization.

As shown in figure 38, when All Ranges A～I all (t0) during nobody detected by the first to the 5th sensor unit 126,128,130,132,134, timer begins timing, after the timing of timer begins at time t1 (for example, 10 minutes) time confirm the people not the time, increase the air quantity of indoor fan 8, and the frequency stage ground of compressor is reduced until time t2 (for example, timing began rear 30 minutes).After elapsed time t1, the air quantity of indoor fan 8 remains constant (limiting value), after elapsed time t2, the frequency of compressor remains constant (limiting value), but at time t2, time t3 (for example works as, timing began rear 1 hour), time t4 (for example, timing began rear 2 hours), confirm during time t5 (for example, timing began rear 4 hours) to continue nobody the time, when time t5, the running of air conditioner is stopped, preventing from that air conditioner from forgetting to be shut down.

In addition, when the existing of people being detected during from time t1 to time t5, return to setting air quantity and setpoint frequency before time t1.

Then, economize electric operation as another, to according to the elapsed time, the method that indoor design temperature is altered to target temperature being described, at first the control when heating describes with reference to table 9 and Figure 39.

(table 9)

Figure 39 represents an example of variations in temperature, at this, to design temperature Tset being set as 28 ℃, target temperature (limiting value) is set as the situation of 20 ℃ describes.In addition, Δ T is the temperature difference of design temperature Tset and target temperature.By the way, target temperature adopt the people not the time take energy-conservation limiting value when making the heating capacity reduction for target.

When All Ranges A～I being detected by the first to the 5th sensor unit 126,128,130,132,134 all during nobody, timer begins timing, after the timing of timer begins, at time t1 (for example, 10 minutes) time confirm the people not the time, design temperature Tset is automatically reduced by 2 ℃ (1/4 Δ T).And then, when confirm when time t2 (for example, timing began rear 30 minutes) people not the time, then design temperature Tset is automatically reduced by 2 ℃ (1/4 Δ T).Below, similarly when when time t3 (for example, timing began rear 1 hour) and time t4 (for example, timing began rear 2 hours) confirmation people not the time, respectively design temperature Tset is automatically reduced by 2 ℃ (1/4 Δ T).Like this, heating capacity is reduced as long as reduce the frequency of compressor along with automatic reduction design temperature Tset.For example, as long as will be until the reduction that t2 carries out be reduced to t5 successively.

When time t4, from design temperature Tset co-falling low 8 ℃ become 20 ℃ of the temperature that equate with target temperature, therefore until time t5 (for example, timing began rear 4 hours) all design temperature Tset is maintained target temperature, but, confirm when at time t5 still the people not the time, stop the running of air conditioner, prevent from that air conditioner from forgetting to be shut down.Like this, can carry out based on not at the Energy Saving Control that detects, the warming operation of avoiding waste, thus reduce power consumption.And, when increase air quantity this moment, by producing simultaneously the static mist and blowing out, can make the static mist spread all over each corner in room, the room NM be can be set as and deodorizing and sterilization carried out.

In addition, when the existing of people being detected during from time t1 to time t5, return to the design temperature Tset before time t1.

In addition, range of temperature (reduction temperature) is set as shown in table 9 according to the temperature difference T of design temperature Tset and target temperature, and temperature difference T is less, and range of temperature is just less.In addition, in the situation that design temperature Tset is lower than target temperature, be maintained the present situation temperature, still, confirm when at time t5 the people not the time, the running that stops air conditioner is identical with the example of Figure 39.

Next, the control during to refrigeration describes with reference to table 10 and Figure 40.

(table 10)

Figure 40 represents an example of variations in temperature, at this, to design temperature Tset being set as 20 ℃, target temperature (limiting value) is set as the situation of 28 ℃ describes.In addition, Δ T is the temperature difference of design temperature Tset and target temperature.

When All Ranges A～I being detected by the first to the 5th sensor unit 126,128,130,132,134 all during nobody, timer begins timing, after the timing of timer begins, at time t1 (for example, 10 minutes) time confirm the people not the time, design temperature Tset is automatically only increased 2 ℃ (1/4 Δ T).In addition, when confirm when time t2 (for example, timing began rear 30 minutes) people not the time, then design temperature Tset is automatically only increased 2 ℃ (1/4 Δ T).Below, similarly when when time t3 (for example, timing began rear 1 hour) and time t4 (for example, timing began rear 2 hours) confirmation people not the time, respectively design temperature Tset is automatically only increased 2 ℃ (1/4 Δ T).

When time t4, increased altogether 8 ℃ and become 28 ℃ of the temperature that equate with target temperature from design temperature Tset, therefore until time t5 (for example, timing began rear 4 hours) all design temperature Tset is maintained target temperature, but, confirm when at time t5 the people still not the time, stop the running of air-conditioning, prevent from that air conditioner from forgetting to be shut down.Like this, can carry out based on not at the Energy Saving Control that detects, the cooling operation of avoiding waste, thus reduce power consumption.And, when increase air quantity this moment, by producing simultaneously the static mist and blowing out, can make the static mist spread all over each corner in room, the room NM be can be set as and deodorizing and sterilization carried out.

In addition, when the existing of people being detected during from time t1 to time t5, return to the design temperature Tset before time t1.

In addition, range of temperature (increase temperature) is set as shown in table 10 according to the temperature difference T of design temperature Tset and target temperature, and temperature difference T is less, and range of temperature is just less.In addition, in the situation that design temperature Tset is higher than target temperature, be maintained the present situation temperature, still, confirm when at time t5 the people not the time, the running that stops air-conditioning is identical with the example of Figure 40.

In addition, the example of above-mentioned Figure 38～Figure 40 is all in the situation that the example of little province's electric operation when usually nobody carries out power consumption than running usually at the appointed time in running, thereafter, again at the appointed time in nobody's situation, stop the running of air conditioner, realize energy-conservation (" running usually " refers to " running of user's indication ").

In addition, although continuing for a long time the people does not exist, but in the situation that the human body detection sensor flase drop measures the people such as the curtain interference in addition that may cause variations in temperature, also consider do not continuing running usually under (unmanned) state always, therefore when through than the long stipulated time t6 of time t5 (for example, 24 hours) time, by shutting down, can prevent from reliably forgetting shutdown.In addition, preferably long stipulated time t6 through being about to before running stops later, gives notice to main body and remote controller with the sense of hearings such as sound or LED lamp ground or vision ground at time t5 or than time t5, or on picture display text.In addition, when arranging on remote controller when automatically stopping selecting arrangement, ease of use improves, and whether this automatically stops selecting arrangement and can select to carry out to stop through automatic running later at time t5 or the stipulated time t6 longer than time t5.
