At this moment, because upside up-down wind direction board 291 is positioned at the cross part of front and the bottom surface of air conditioner, the outside wind direction face outside therefore becoming becomes smooth and curved surface that curvature is big and consistent with the profile of air conditioner.By like this, upside up-down wind direction board 291, downside up-down wind direction board 292 usefulness become the wind direction face of outside can the formation of continuously smooth ground from the front of air conditioner to the profile of bottom surface.

Therefore, when not using air conditioner, the infra-red ray detection device 14 that can be called the eye of air conditioner is also hidden by upside up-down wind direction board 291, and the outward appearance of air conditioner becomes the shape that does not have unnecessary concavo-convex soft coordination, can not upset indoor atmosphere.

When air conditioner carried out cold air operation, as shown in Figure 5, upside up-down wind direction board 291, downside up-down wind direction board 292 were in the direction of the posture of the upper wall 290a, the lower wall 290b almost parallel that blow out air channel 290 or level and use.And, directly contact and produces offending occasion with indoor occupant at the cold wind that blows out, suitably change the direction of up-down wind direction boards 291,292 and left and right sides wind direction board 295 with remote controller 5, will indoor occupant remain comfortable temperature and humidity on every side.

When carrying out the running of extremely weak cold air or heating installation, upside up-down wind direction board 291 is made progress as shown in figure 20 a little, make downside up-down wind direction board 292 postures of roughly closing that are in shown in dotted line, make to blow out expansion section, the top 290e that enlarges upward that air flow direction is arranged at the downstream that blows out air channel 290.Thus, the part of blow out air becomes extremely weak wind and passes through expansion section, top 290e lightly to indoor diffusion, carries out the running of faint cold air or heating installation.

And by utilizing top expansion section 290e, the short circuit running that the wind that carries out blowing out sucks from suction inlet 27 immediately can also be carried out the maintenance action of air conditioners such as deodorizing running of dried the make an uproar running and the air conditioner inside of heat exchanger.

When air conditioner carried out the heating installation running, up-down wind direction board 291,292 was in roughly subvertical posture as shown in Figure 6 and uses.By like this, the Wen Fengcong air conditioner that flows in blowing out air channel 290 blows out downwards, until arriving near the ground, near the warm underfooting, makes the indoor comfortable environment that becomes.

Then, use Fig. 7～Figure 14 that the infrared ray sensor that air conditioner of the present invention carried is described.Fig. 7 is the stereoscopic figure of indoor set.Fig. 8 has been opening of the indoor set stereoscopic figure of up-down wind direction board.Fig. 9 is loaded on the structure chart of the infra-red ray detection device in the indoor set in being.Figure 10 is the Fresnel lens allocation plan of checkout gear.Figure 11 is the detection range figure of checkout gear.Figure 12 is the outside drawing of checkout gear, (a) is vertical view, (b) is front view, (c) is side view, (d) is the installment state side view.Figure 13 is the surveyed area figure according to checkout gear.Figure 14 is the circuit structure diagram of checkout gear.

Generally, the occasion of people detection device is installed on air conditioner, its main purpose is to make air conditioner carry out energy-saving operation when not having indoor occupant or stop, carry out carrying the dedicated operation of wind etc. and realizing energy-conservationly at indoor occupant after a little while, and can avoid being accompanied by people's the loaded down with trivial details operation of moving to this few people.

In order to realize this purpose, the people detection device that is provided with the infrared ray sensor etc. of electrothermic type is provided with a plurality of, be divided into a plurality of zones with indoor, detect and observe indoor occupant from air conditioner and be positioned at which position.This occasion is carried out following setting, promptly do not form non-surveyed area between the surveyed area of people detection sensor, and the surveyed area of people detection sensor does not overlap each other.

At this moment, in unique people detection sensor response occasion, can know that the surveyed area at this people detection sensor has the people, but when a plurality of infrared ray sensors that surveyed area repeats have reacted, consider that the people concentrates on situation, people that the situation of repeat region, people be dispersed in exclusive mutually zone and is dispersed in the situation in exclusive zone of a repeat region and a side and the situation that the people is dispersed in repeat region and the exclusive zone of both sides, in order to distinguish these zones, increase the quantity of sensor or the sensor of other modes is installed, replenish scarce capacity part each other.

In embodiment 1, as shown in Figure 8 infra-red ray detection device 14 is located at the above-mentioned central portion that blows out the length direction of top, air channel expansion section 290e, when running stops, covering from indoor with upside up-down wind direction board 291 as shown in Figure 7, prevent to bring inharmonious sense to indoor.

Infra-red ray detection device 14 carries on substrate 416 by pedestal 415 infrared ray sensor 410 as shown in Figure 9 and covers Fresnel lens 417, and configuration about this is constituted as shown in figure 12.

Infrared ray sensor 410 has level and smooth sensitive surface 411, the relative direction of sensitive surface 411 become main detection side to, from the center of sensitive surface 411 towards main detection side to central shaft 412 become the best direction of detection sensitivity, around it, expand detection sensitivity good detection scope.

About infrared ray sensor 410a, c utilize above-mentioned pedestal 415, carry into the direction difference of central shaft 412, certainly its main detection side is to also different, therefore can form the detection range of wide-angle as shown in figure 11, and, the major part of flooring can be accommodated in its visual field by infra-red ray detection device 14 is installed with the angle of depression shown in Figure 12 (d).

Fresnel lens 417 is shaped to as shown in figure 10 and is hemisphere face, hemisphere face is divided into a plurality of sections, be formed with little Fresnel lens so that will concentrate on hemispherical central part at each section, at the sensitive surface 411 of this hemispherical central portion configuration infrared ray sensor 410 from the infrared ray of indoor specific direction.

If near the face parallel to the ground height of the face of will this little Fresnel lens concentrated ultrared direction when taking one's seat is represented, then become the distribution of test point as shown in figure 13, if people's several test points of coming in and going out in this scope, then infrared ray sensor 410 detects it.In an embodiment, imagination is in the indoor use of family, and set for from the size of a test point of the position of separating 6m from infrared ray sensor 410 roughly with the equal and opposite in direction (width 0.3～0.5, height 1.6～1.8) of human body.

In an embodiment, use the infrared ray sensor of electrothermic type as infrared ray sensor 410.Infra-red ray detection device 14 comprises Zuoren detecting sensor 140a, right people detection sensor 140c and s operation control portion 132 as shown in figure 14, about people detection sensor 140a, c comprise the output of infrared ray sensor 410a, c, amplification infrared ray sensor 410a, c amplifier 130, extract the band filter of people's activity out, this output be converted to comparator 131 and above-mentioned pedestal 415, the Fresnel lens 417 etc. of data signal.

Generally, when the people awakens, can not on physiology, continue static, the part of healths such as movable hand, pin, face consciously or among unconscious in several minutes.

Infrared ray sensor 410a, c in people detection sensor 140a, the c detect this activity, and output signal.Be converted to by people detection sensor 140a, c from the output of infrared ray sensor 410a, c and be suitable in the form of the processing of s operation control portion 132 and read in s operation control portion 132,, carry out the control of the ability, wind direction etc. of air conditioner according to the result of calculation process.

As mentioned above, if constitute infra-red ray detection device 14, then be accompanied by the analog signal of activity of existence, the human body of environment and human body from described current pyroelectric infrared sensor 410a, c output, amplified by above-mentioned amplifier 130, extract near the signal the 1Hz of the activity that mainly is contained in the people out with above-mentioned band filter, utilize above-mentioned comparator 131 to remove small signal and interference, and be converted to digitized active pulse.

The signal that is converted to active pulse is imported above-mentioned s operation control portion 132 from the port that reads in of above-mentioned s operation control portion 13, carries out calculation process.According to its result, to being judged as the zone that has human body, towards or avoid above-mentioned up-down wind direction board 291,292, left and right sides wind direction board 295, utilize indoor Air Blast fan 311, the air that feed adjustment is good.

Then, use Figure 15～Figure 17 that the variation from the signal of infrared ray sensor 410 of moving according to indoor people is described.Figure 15 is the figure of the activity when representing in people's inlet chamber.Figure 16 is the waveform output of the people detection sensor under the situation of Figure 15, (a) be the analog waveform of left infrared ray sensor output, (b) be the digital waveform of Zuoren detecting sensor output, (c) being the analog waveform of right infrared ray sensor output, (d) is the digital waveform of right people detection sensor output.Figure 17 is the surveyed area division figure of people detection sensor.

As shown in figure 15, people 907 is from position P inlet chamber 902, and when moving to position S through position Q, R, the analog signal of infrared ray sensor 410a output shown in Figure 16 (a) of people detection sensor 140a.When people detection sensor 140a has surpassed certain level at the absolute value of this simulation output, in order to export active pulse (being the Hi pulse in an embodiment), should simulate output and handle, and be converted to the digital waveform shown in Figure 16 (b) and export to s operation control portion 132 with amplifier 130, comparator 131 etc.This digital waveform is read in some cycles, the number of times that the computational activity pulse detection goes out in s operation control portion 132 inside at infra-red ray detection device 14.Detection number of times during stipulated time become be used as have the people exist threshold value above the time, when for example the people was positioned at position Q, R, s operation control portion 132 judged that Zuoren detecting sensor 140a detect the people.Equally, infrared ray sensor 410c, right people detection sensor 140c be output signal as Figure 16 (c), (d) also, and similarly, when for example the people was positioned at position R, S, s operation control portion 132 judged that right people detection sensor 140c detects the people.

In the above description, for convenience of explanation, write as the judgement that can make the people as each moment of moving the people, but in an embodiment the afore mentioned rules time was made as 30 seconds, so only with enter the room and move between the reaction of only several seconds can not make people's judgement, the reaction of perceiving the activity of the nature of people after stopping to move could determine the position.Like this, by suitably selecting the afore mentioned rules time, only be by the time, judging has the people, can reduce the worry of carrying out unwanted control significantly.And, by using two infrared ray sensors 410, only surveyed area can be divided into the zone of detecting by Zuoren detecting sensor 140a, the zone of only detecting by right people detection sensor 140c, by about these three zones, zone of detecting of people detection sensor 140a, c.

In addition, in an embodiment active pulse is made as the Hi pulse, but self-evident, on the contrary will indoor people not the time the output of people detection sensor 140 be made as Hi, output during with people's activity is made as Lo, thereby the detection number of times that calculates the active pulse of Lo also can.

Infra-red ray detection device 14 is installed on the indoor set 2, in order to simplify this surveyed area, drop to the height on ground and expression as shown in figure 17, as mentioned above will be indoor be divided into by about people detection sensor 140a, c separately detection surveyed area 610A, C and by about people detection sensor 140a, surveyed area 610A, the C of c duplicate detection.And, for convenience of explanation, sometimes regional 610A brief note is (1), regional 610C brief note is (2), regional 610AC brief note is (3).

Only by the detected occasion of Zuoren detecting sensor 140a, infer human body and be present in surveyed area 610A, only by the detected occasion of right people detection sensor 140c, infer human body and be present in surveyed area 610C, by Zuoren detecting sensor 140a and the detected occasion of right these both sides of people detection sensor 140c, infer human body and be present in surveyed area 610AC or surveyed

area

610A and 610C and 610AC.

Use Figure 18 that the structure in zone is described here.Figure 18 is the key diagram in zone, (a) be A and C's or (with) the zone, be the zone of the XOR (exclusive and) of A and C (b), (c) be the zone of having got rid of C poor (poor) from A, (d) be the zone of having got rid of the difference of A from C, (e) be A and C with (Plot) the zone.

In an embodiment, from zone that the output of people detection sensor 140 is estimated as the people by about people detection sensor 140a, c surveyed area or, XOR, difference or with constitute.Shown in Figure 18 (a), represent with mark A at surveyed area A Zuoren detecting sensor 140a, when the surveyed area C of right people detection sensor 140c represents with mark C, with oblique line portion regional A and zone C or that be defined as Figure 18 (a), the XOR of regional A and zone C is defined as the oblique line portion of Figure 18 (b), the difference of regional A and zone C is defined as the oblique line portion of Figure 18 (c), the difference of zone C and regional A is defined as the oblique line portion of Figure 18 (d), with regional A and zone C with the oblique line portion that is defined as Figure 18 (e).This definition can be analogized easily from the group theory, and understands easily.

Then, use Figure 19～Figure 22 that the division according to the room area of the vertical direction of up-down wind direction board is described.Figure 19 is a key diagram of dividing surveyed area with up-down wind direction board.Figure 20 is territory, the far field detected state figure according to up-down wind direction board.Figure 21 is the middle regional detected state figure according to up-down wind direction board.Figure 22 is the near field detected state figure according to the direction wind direction board.

In an embodiment, except the division of the indoor surveyed area of the left and right directions of above-mentioned air conditioner, use the indoor surveyed area of also dividing of the depth direction of 291 pairs of air conditioners of up-down wind direction board.As mentioned above, upside up-down wind direction board 291 has the effect that expansion section, the top 290e that enlarges the upward guiding that is located at the downstream that blows out air channel 290 is blown out air-flow.When detecting the having or not of indoor occupant, make this upside up-down wind direction board 291 turn to part cover people detection sensor 140 the visual field the position and stop.Making position that upside up-down wind direction board 291 stops as shown in figure 19, is the position that front end at the image of upside up-down wind direction board 291 has marked mark i, j, k, m, and these positions are called upside up-down wind direction board position 491i, j, k, m.

The full visual field at upside up-down wind direction board position 491i people detection sensor 140 is hidden by upside up-down wind direction board 291, can not detect having or not of indoor occupant.At upside up-down wind direction board position 491j, have only detection range 591j to detect in the visual field of infra-red ray detection device 410.Have only detection range 491k to detect at upside up-down wind direction board position 491k.At upside up-down wind direction board position 491m, detection range 591m=can detect in the full visual field.

Side up-down wind direction board 291 detects the occasion of the position of indoor occupant in the use, at first, makes upside up-down wind direction board 291 stop at upside up-down wind direction board position 491j as shown in figure 20, and personnel selection detecting sensor 140 detects having or not of indoor occupant.Then can know that indoor occupant be present in detection range 591j if detect indoor occupant this moment.

Then, make upside up-down wind direction board 291 stop at upside up-down wind direction board position 491k as shown in figure 21, personnel selection detecting sensor 140 detects having or not of indoor occupant.Then can know that indoor occupant be present in the detection range 591k that comprise detection range 591j if detect indoor occupant this moment.And the detection action before using can know that in the occasion that detection range 591j does not detect the people people is present in the scope of having got rid of detection range 591j from detection range 591k.

Then, make upside up-down wind direction board 291 stop at upside up-down wind direction board position 491m as shown in figure 22, personnel selection detecting sensor 140 detects having or not of indoor occupant.Then can know that indoor occupant be present in the detection range 591m that comprise detection range 591k if detect indoor occupant this moment.And the detection action before using can know that in the occasion that detection range 591k does not detect the people people is present in the scope of having got rid of detection range 591k from detection range 591m.

Then, use Figure 23～Figure 25 to according to the having or not of personnel selection detecting sensor 140 detected indoor occupants, the method for inferring the existence area of depth direction describes.Figure 23 is the surveyed area division figure according to the far and near direction of up-down wind direction board from observing with vertical guide.Figure 24 is the surveyed area division figure according to the ground of up-down wind direction board.Figure 25 is the surveyed area division figure according to infrared ray sensor and up-down wind direction board.

To then become Figure 23 by above-mentioned three divisions that detect result that action obtains corresponding to the indoor depth direction of observing from air conditioner.Make upside up-down wind direction board 291 stop at upside up-down wind direction board position 491j and detecting the occasion that has or not of indoor occupant, the visual field of people detection sensor 140 is limited in detection range 591j, so can detect the indoor occupant of surveyed area 691J.

And, make upside up-down wind direction board 291 stop at upside up-down wind direction board position 491k and detecting the occasion that has or not of indoor occupant, the visual field of people detection sensor 140 expands to detection range 591k, so can detect the indoor occupant of surveyed area 691J, K.

Also have, make upside up-down wind direction board 291 stop at upside up-down wind direction board position 491m and detecting the occasion that has or not of indoor occupant, the looking of people detection sensor 140 do not covered fully and expanded to detection range 591m, so can detect all surveyed area 691J, K, the indoor occupant of M.

Then become Figure 24 if observe of the expansion of above-mentioned surveyed area, can on indoor depth direction, divide surveyed area on ground.

Like this, use above-mentioned a plurality of people detection sensor 140a, c shown in Figure 11 to divide along left and right directions with indoor, and use upside up-down wind direction board 291 to divide along fore-and-aft direction with indoor, thereby as shown in figure 25 with indoor edge all around direction be divided into 9 zones intersect detecting regional 710JA～MC, that can know indoor occupant exists direction and its depth scope, can suitably control air conditioner thus.

In addition, in the above description, for convenience of explanation, the border of surveyed area is set at the position on the arrival ground, border of detection range, but in fact, because whether whether whether the people's that people detection sensor 140 detects easily face, the position of nape are stood, are sitting on the chair, sit in bed or do not lie on a bed etc. with the people different, the boundary line of strictly obtaining surveyed area is the thing of comparison difficulty.But, divide roughly that the people is present in indoor position far away, is present in position intermediate, near the situation being present in and so on is can be enough to accomplish.It is the expansion at center that the air conditioning scope of air conditioner also has with the place as purpose, so even also can obtain enough effects according to the air conditioner of aforesaid division.

Then, use Figure 26, Figure 27 that people's detection method is described.Figure 26 detects step major part flow chart.Figure 27 is input signal gate time figure.

The air conditioner of embodiment is inferred in indoor people's position, the control air conditioner, so that carry out suitable air conditioning according to this position, Figure 26 is a flow chart of judging the position that the people is arranged, below with reference to this figure the method for the position of inferring the people is described.

In step S1, enter between the detection zone of stipulated time of the people in the sensing chamber at infra-red ray detection device 14, read in from the signal of people detection sensor 140 input s operation control portions 132 with certain cycle as mentioned above, computational rules is output as the number of times of Hi in the time, obtain the detection number of times of active pulse.In an embodiment, as shown in figure 27, read in 30 seconds with the cycle of 10ms, at Hi the number that increases a Zuoren detecting sensor from the input signal of Zuoren detecting sensor 140a during for Hi.And, in the drawings, Zuoren detecting sensor 140a, right people detection sensor 140c brief note is left sensor, right sensor.

Equally, at Hi the number that increases a right people detection sensor from the input signal of right people detection sensor 140c during for Hi, will be through the detection number of times of stipulated time number of times before as each one detecting sensor.And, to the cycle of reading in be made as 10ms in an embodiment, but be thought of as which degree according to the resolution ratio of Fresnel lens and people's translational speed, the proper range in this cycle changes, if indoor being used for as family considered, then if the cycle of 50ms, to just not having obstacle in indoor movable fast detection.And, become shorter than 10ms even the cycle of reading in shortens, the situation that detects people's the accuracy rate of activity and cycle 10ms is roughly the same, does not have obstacle in the detection to people's activity, but the quantitative change of the data that s operation control portion 132 handles is big, so even the shortening cycle also invalid.

Then, use the ad hoc approach of the position that the people is arranged of Figure 26, Figure 28～Figure 32 to describe.There is the interim criterion in zone in Figure 28.Figure 29 be the people detection sensor active pulse the detection number of times and have the corresponding diagram A in zone, (a) be not situation, (b) be the situation that the people is positioned at zone, a left side, (c) be the situation that the people is positioned at right zone.Figure 30 is the table that there is the interim judgement in zone in expression.Figure 31 be both sides the people detection sensor for the zone of situation select key diagram, be that the people concentrates on the situation of (3) (a), (b) be the situation that the people is dispersed in zone (1)+(2)+(3).Figure 32 is the detection number of times and the regional corresponding diagram B of existence of the active pulse of people detection sensor, (a) is the situation that the people concentrates on middle section, (b) is the situation that the people is dispersed in Zone Full.

In the step S2 of Figure 26, with the detection number of times of the active pulse of above-mentioned each one detecting sensor 140 as shown in figure 28 with exist threshold ratio, at the detection number of times of the active pulse of Zuoren detecting sensor 140a when existing threshold value above, assert that Zuoren detecting sensor 140a detects the people, when existing threshold value above, assert that right people detection sensor 140c detects the people at the detection number of times of the active pulse of right people detection sensor 140c.

At this moment, shown in Figure 29 (a), about the detection number of times of active pulse of people detection sensor 140a, c when all there is threshold value in deficiency, assert indoor nobody.And for existing more than the threshold value, and the detection number of times deficiency of the active pulse of right people detection sensor 140c is when existing threshold value as the detection number of times of the active pulse of Figure 29 (b) Zuoren detecting sensor 140a that is shown in, and thinking has people's existence zone to be regional 610A.And, have threshold value as the detection number of times deficiency of the active pulse of Figure 29 (c) Zuoren detecting sensor 140a that is shown in, and the detection number of times of the active pulse of right people detection sensor 140c thinks that it is regional 610C that people's zone is arranged when existing threshold value above.

The detection number of times of the active pulse of people detection sensor 140a, c in addition, is to exist the above situation of threshold value to consider following 5 situations.

(i) people is positioned at the regional 610AC of central authorities.

(ii) the people is positioned at regional 610A and regional 610C.

(iii) the people is positioned at regional 610A and regional 610AC.

(iv) the people is positioned at regional 610AC and regional 610C.

(v) the people is positioned at regional 610A and regional 610AC and regional 610C.

If sum up these contents from the viewpoint of control air conditioner, then being divided into lets others have a look at as (i) concentrates the regional 610AC be positioned at central authorities and narrow region is carried out situation that air conditioning gets final product and as (ii) (iii) (iv) (v) being leted others have a look at and be dispersed in the wide indoor and situation of widely indoor integral body being carried out air conditioning with point-like.Below, with this with (i) people be positioned at central authorities regional 610AC situation and (v) the people is dispersed in the situation of regional 610A and regional 610AC and regional 610C as representative.

If sum up above-mentioned relation then become shown in Figure 30, for about people detection sensor 140a, the situation that c all detects the people, two zones exist regional candidate to appear in one's mind as the people.

Then, illustrate that existing regional candidate to select from above-mentioned two exists regional method.The people is positioned at the occasion of regional 610AC, same people's activity by about people detection sensor 140a, c detect, so about people detection sensor 140a, c shown in Figure 31 (a), represent roughly the same reaction, the detection number of times of active pulse also becomes roughly the same detection number of times, so about poor (s) of the not enough regulation of difference of detection number of times of active pulse of people detection sensor 140a, c the time, think that shown in Figure 32 (a) the existence zone that the people exists is regional 610AC.

In addition, be dispersed in the occasion of regional 610A and regional 610AC and regional 610C the people, about people detection sensor 140a, c detect the people, everyone is different and the amount of people's activity is with the moment, therefore the result of activity who detects a plurality of different people is different certainly, and the difference of the detection number of times of active pulse becomes big.Thereby, be poor (s) of afore mentioned rules when above in the difference of the detection number of times of active pulse, shown in Figure 32 (b), think that the existence zone that the people exists is regional 610A and regional 610AC and regional 610C.

At this moment, except the detection number of times difference of simple active pulse, for example only detect people's detecting sensor 140 active pulse this moment not enough stipulated number occasion think that (a) people is present in the regional 610AC of central authorities, the occasion more than regulation can think that (b) people is present in regional 610A and regional 610A and regional 610C.

Like this, read in some cycles between the detection zone of stipulated time about people detection sensor 140a, the output of c, and the number of times when calculating Hi is obtained the detection number of times of active pulse, according to detect existence that number of times determines the people whether with have the zone.

Its result, can with people's existence whether with exist the zone be divided into Figure 29 (a) not in the zone (1) of, Figure 29 (b), these 5 of zone (1)+(2)+(3) of the zone (3) of the zone (2) of Figure 29 (c), Figure 32 (a), Figure 32 (b).

This occasion, (1), (2), (3) they are unit area, (1)+(2)+(3) are the zones of combination (1)+(2) of having represented a plurality of unit areas, (1)+(3), (2)+(3), (1)+(2)+(3).

Then, use Figure 33 that the summary of the decision method in final existence zone is described.Figure 33 inferred the method key diagram in 2 stages.

Above-mentioned beginning between detection zone is called interim judgement interval to the interval of the beginning between next detection zone, the people's who between this detection zone, obtains existence whether with exist the zone to be called interim result of determination.With the region repeated number of times of stipulating of this interim judgement,, carry out final decision according to these interim result of determination.In other words, as shown in figure 33, judge between the detection zone that has the shorter stipulated time in the interval, judge according to the testing result between detection zone, and the interim result of determination of number of times is carried out final decision according to the rules temporarily than this interim.

Therefore, the result of final decision has reflected the testing result in the time interval of the interim judgement length of an interval that comprises these stipulated numbers, with the mobile tendency that the long time is caught the people, obtain people's position reliably, the result controls air conditioner according to this final decision.

This be because, in the occasion of keeping indoor comfort with air conditioner, if the frequent state that changes air conditioner, then control is unstable, often bring unhappiness, so when variation having taken place, catch its variation in the place that the people is arranged to indoor occupant, with nature to feel to transfer to new place be the air conditioning at center, thereby make control become stable and need not frequent change.

Then, use Figure 26, Figure 34, Figure 35 that the detection of the activity of indoor occupant is described.Figure 34 is the interim criterion of grade of the size of activity, (a) is the situation that the people is present in (1) or (2), (b) is that the people is present in the situation of (3), (c) is the situation that the people is present in (1)+(2).Figure 35 is the interim criterion of grade of the size of activity, (a) is the situation that the people is present in single zone, (b) be the people be present in the situation in a plurality of zones or not situation.

In the step S2 of Figure 26, except above-mentioned people's existence whether with the interim result of determination that has the zone, obtain the grade of size of indoor people's activity.The grade classification of the size of indoor people's activity be little, in, big Three Estate, roughly can followingly stipulate.

The grade of the size of activity [greatly]: the people is dispersed in (1)+(2)+(3), and reaction is big.← people is movable in wide region.

The grade of the size of activity [in]: the people is dispersed in (1)+(2)+(3), and reaction is few.← people is suitably movable in wide region.Perhaps, the people is present in (1), (2) or (3), and reaction is many.← people is suitably movable in close limit.

The grade of the size of activity [little]: the people is present in (1), (2) or (3), and reaction is few.← people is suitably movable in close limit.

The grade of the size of activity be made as Three Estate be because, in home-use air conditioner according to common Architectural Construction and width and consider the number of indoor occupant, can obtain required cold air, heating installation ability simply, so the big state of the grade of number people size of movable activity in wide region and the rated capacity of air conditioner roughly match.On the other hand, in the little occasion of activity, need carry out energy-saving operation, the scope of therefore adjusting design temperature up and down is to the maximum about 2 ℃ to prevent to lose comfortableness.According to these situations, though with the grade classification of activity for a lot of also just the variation of design temperature segmented, to energy-conservation effect big difference very not.Therefore, in order to simplify control, the grade classification of the size of activity is relatively more real about three.

For the size of indoor people's activity is divided as mentioned above,, and be divided into as shown in figure 35 according to Figure 34 according to the detection number of times of the interim result of determination and the active pulse in above-mentioned existence zone.

There is the situation of zone for (1) or (2) in Figure 34 (a), about the occasion of the not enough activity threshold value 1 of detection time number average of which active pulse of people detection sensor 140a, c, the grade of the size of activity is made as " little ", in the occasion of activity threshold value more than 1, the grade of the size of activity is made as " in ".

There is the situation of zone for (3) in Figure 34 (b), about the occasion of average not enough activity threshold value 1 of detection number of times of active pulse of people detection sensor 140a, c, the grade of the size of activity is made as " little ", in the occasion of activity threshold value more than 1, the grade of the size of activity is made as " in ".

Figure 34 (c) exists the zone to be the situation of (1)+(2)+(3), about the occasion of the not enough activity threshold value 2 of summation of detection number of times of active pulse of people detection sensor 140a, c, the grade of the size of activity is made as " in ", in the occasion of activity threshold value more than 2, the grade of the size of activity is made as " greatly ".And, the people not occasion think the grade of the size of minimum activity, the grade of the size of activity is " little ".

If sum up foregoing, then according to people's existence whether with exist the zone and about the detection number of times of active pulse of people detection sensor 140a, c, exist the zone shown in Figure 35 (a), to obtain interim result of determination for the occasion of (1), (2) or (3), and, exist the zone for (1)+(2)+(3) or not occasion shown in Figure 35 (b), obtain interim result of determination.

Then, use Figure 26, Figure 36, Figure 37 to can clearly having people's situation to describe with a temporary detecting.Figure 36 is promptly fixed (decision immediately) criterion, (a) is the situation that the people is present in single zone, (b) is the situation that the people is present in a plurality of zones.Figure 37 promptly decides result of determination summary figure, (a) is the situation that the people is present in single zone, (b) be the people be present in the situation in a plurality of zones or not situation.

In the step S3 of Figure 26, judge the interim detection number of times of judging interval active pulse whether be that fixed condition is consistent.Be that fixed condition is the condition that is used for existing according to the interim clear and definite reliably people of result of determination once the zone, according to above-mentioned people's existence whether and the detection number of times of interim result of determination and active pulse, and judge as shown in figure 37 according to Figure 36.

There is the situation of zone for (1), (2) or (3) in Figure 36 (a), about the detection number of times of which active pulse of people detection sensor 140a, c surpass than exist threshold value big promptly decide (Ji Decision) occasion of threshold value 1 thinks to be that fixed condition is set up, deficiency is promptly decided the occasion of threshold value 1 and is thought to be that fixed condition is false.

Figure 36 (b) exists the zone to be the situation of (1)+(2)+(3), about the summation of detection number of times of active pulse of people detection sensor 140a, c surpass than promptly deciding the threshold value 1 bigger occasion of promptly deciding threshold value 2 to think to be the fixed condition establishment, deficiency is promptly decided the occasion of threshold value 2 and is thought to be that fixed condition is false.

Sum up foregoing, then according to the detection number of times of the active pulse that has zone and people detection sensor 140a, c, there being the zone is the occasion of (1), (2) or (3), whether shown in Figure 37 (a), obtain and be that fixed condition is consistent, and, there being the zone is the occasion of (1)+(2)+(3), shown in Figure 37 (b) whether be that fixed condition is consistent, occasion does not think to be that fixed condition is false.

Be that the occasion that fixed condition is set up advances to step S7, promptly the invalid occasion of fixed condition advances to step S4.

In step S4, judge the interim judgement of whether having carried out as N time (the occasion N=4 of embodiment) of stipulated number.The interim occasion of judging of carrying out the not enough stipulated number of number of times is returned step S1, enter next interim judge interval, the existence of carrying out the people once more whether with the interim judgement that has the zone.

The interim judgement of occasion end that number of times has reached stipulated number of carrying out in the interim judgement of step S4 advances to the step S5 that carries out final decision, judges whether N time interim result of determination all is not exist.

In step S5 N interim result of determination all be not occasion advance to step S6, think indoor continuation not possibility big, change design temperature significantly, further strengthen energy-conservation described laterly do not control at energy-saving operation, return step S1, enter and judge the interval next time, carry out the detection action in the first interim judgement interval.

The interim result of determination that has the zone at step S5 advances to step S8 for the occasion more than once, the existence of carrying out current people according to N interim result of determination and last final decision result whether with the final decision of the grade of the size that has zone and activity, advance to step S9.

At step S3 is the occasion that fixed condition is set up, and will be that the interim result of determination in the interim judgement interval of fixed condition establishment adopts as the final decision result in step S7, advances to step S9.

In step S9, as mentioned above, carry out the people detection in the zone of indoor depth direction division of upside up-down wind direction board 291 as the shield use of infrared ray sensor 410 advanced to step S10.

In step S10, as described later, upgrade the resume that have the zone, according to the people detection result of above-mentioned final decision result, depth direction, the control air conditioners such as resume in existence zone, turn back to step S1, enter and judge the interval next time, carry out the detection action in the first interim judgement interval.

Use Figure 38 that above step is carried out schematic illustration.Figure 38 controls key diagram repeatedly.

As shown in figure 38, the final decision of people's position generally is to carry out in each judgement interval with certain hour, air conditioner be controlled at each final decision the time upgrade or keep.

This judge a plurality of (N: N=4) in an embodiment that have regulation in interval interim judge interval, interval in each interim judgement, during between the detection zone of the stipulated time shorter than interim judgement interval, read in the output of people detection sensor 140, handle the data of reading in and carry out above-mentioned interim judgement.

Interim judgement is carried out in each interim judgement interval, according to each interim result who judges and last final decision result, the people's that final decision is current location.

And, the big than usual occasion of output as the people detection sensor 140 in the interim judgement interval on the basis of interim judgement, shown in the dotted arrow of Figure 38, omit later interim judgement interval, as promptly deciding final decision, adopt this interim interim result of determination of judging the interval, as the final decision result.

In addition, equipment as the control object, except the interior compressor that is loaded in the air conditioner, the refrigerant loop control device, Air Blast fan, left and right sides wind direction board, up-down wind direction board, outside the display unit etc., also has air interchanger, aircleaning facility, odor removal, electrostatic atomization apparatus, the anion generating means, damping device, apparatus of oxygen supply, invade various devices such as checkout gear, whether can carry out the running of equipment/stop according to people's existence, the change of ability, the conversion of heating installation/cold air/dehumidifying, the direction change of blow out air, detect the threat/alarm/notice of effractor's occasion etc.

Like this, the air conditioner of embodiment possesses the cabinet with air suction inlet and air blow-off outlet, be configured in the heat exchanger in the above-mentioned cabinet, suck room air and Air Blast fan from above-mentioned air suction inlet by blowing out from above-mentioned air blow-off outlet after the above-mentioned heat exchanger, be located at the left and right sides wind direction board that blows out the air channel of above-mentioned Air Blast fan, up-down wind direction board, and has infrared ray sensor also with the indoor infra-red ray detection device that has or not that is divided into a plurality of zones and infers indoor occupant, whether existence the judgement people sets a plurality of interim judgement interval of stipulating with the judgement interval that has the zone, whether regional with existence interim judgement people's existence is, the occasion that surpasses the threshold value of regulation in value based on the output of the infrared ray sensor in above-mentioned interim judgement interval, result based on a plurality of interim judgements of afore mentioned rules, whether regional with existence final decision people's existence is, surpassed the occasion of the threshold value of regulation in value based on the output of the infrared ray sensor in above-mentioned interim judgement interval, with the result of the interim judgement in above-mentioned interim judgement interval as final decision.

Thus, the usual judgement interval of length of adopting, the long-term variation in the sensing chamber is so disappeared by the misoperation of the variations disturb of short-term.And, will judge that interval division is a plurality of interim judgements intervals, each interim judge intervally judge and hold indoor situation temporarily, so there is not the skew of information in the information in the trap chamber everywhere, accurately captured information.

And, data in interim judgement is interval only are used for interim judgement, and in interim judgement, select unique result, even so interim judge interval in the data contention of a plurality of interim judgement candidates and occasion that the result of interim judgement is changed constantly, though based on the result's of a plurality of interim judgements final decision be a little but stably be maintained the interim judgement candidate of advantage.

In addition, when the interval detection output of interim judgement has arbitrarily obviously increased, be omitted with this interval continuous interim judgement interval of interim judgement, be output as the basis with the interim judgement interval of detecting the obvious increase of output and carry out final decision, so shortened time, guaranteed the adaptability of control until final decision.

Like this, usually focus on the reliability, carry out final decision so that the sufficient judgement that can judge reliably is interval with can the guarantee control interval that changes stably and the time interval of the depositing of not damaging indoor comfort, so can not damage indoor comfort, on the other hand, in the time will judging that the interval output that is divided into a plurality of interim judgement intervals has obviously increased, carry out final decision immediately, so also guaranteed adaptability.

Therefore, can provide reliably and promptly judge has people's zone, and does not damage indoor comfort and the air conditioner suitably controlled.

In addition, its above-mentioned zone of the air conditioner of embodiment be with the surveyed area of a plurality of above-mentioned infrared ray sensors or, XOR, difference or with the zone of dividing, whether above-mentioned people's existence is to carry out according to the output time in the stipulated time of the active pulse of carrying out numeral output based on the output of the above-mentioned infrared ray sensor relevant with the structure of above-mentioned zone with the interim judgement that has the zone.

Thus, set a plurality of zones (comprising the combination in a plurality of zones) at the surveyed area of a plurality of infrared ray sensors, each zone is caught by the visual field of one or more infrared ray sensors (surveyed area), activity to each regional people is reacted, and the output with infrared ray sensor of the surveyed area relevant with the formation on this regional border changes.Like this, if the people persists in zone arbitrarily, then this people conscious activity especially, because the caused physiological activity of existence itself, the output of the infrared ray sensor relevant with this regional structure continues to change during people's existence.Catch the variation of the output of this infrared ray sensor, signal from infrared ray sensor output expression activity, so by obtaining and analyze summation length with this digitized active pulse, catch the variation of the continuation of above-mentioned people's duration of existence, can determine whether regional with existence indoor people's existence is.

Therefore, can provide the air conditioner of suitably selecting to exist the zone according to the combination of the output of infrared ray sensor.

In addition, the air conditioner of embodiment reads in numeral output based on the output of above-mentioned infrared ray sensor with certain cycle, surpass at the detection number of times of the above-mentioned active pulse of afore mentioned rules in the time and to exist the occasion of threshold value to regard as existence, at above-mentioned detection number of times is to exist occasion below the threshold value to regard as not exist, according to the existence of temporarily judging the people based on the combination of the above-mentioned detection number of times of the above-mentioned active pulse of the output of the above-mentioned infrared ray sensor relevant with the structure of above-mentioned zone whether with have the zone.

Thus, can obtain the summation of the length of above-mentioned active pulse to detect number of times, can distinguish the people not and exist.By suitably determine this people of difference with the detection number of times that exists and as there not being threshold value, can distinguish not existing in each zone.And, export the infrared ray sensor that surpasses the result's who has threshold value signal and had a plurality of occasions, by the detection number of times of analysis, can further the surveyed area of these a plurality of infrared ray sensors be divided into the zone of segmentation based on the active pulse of the output of these a plurality of infrared ray sensors.

Therefore, can provide suitably interim judgement whether to exist, suitably select to exist the air conditioner in zone.

In addition, the air conditioner of embodiment the above-mentioned detection number of times of afore mentioned rules in the time for than above-mentioned exist threshold value big promptly decide threshold value when following, a plurality of interim result of determination and last final decision result based on afore mentioned rules, whether regional with existence the people's that final decision is current existence is, surpass at the above-mentioned detection number of times of afore mentioned rules in the time above-mentioned when promptly deciding threshold value, with the result of the interim judgement in above-mentioned interim judgement interval as current people's existence whether with have regional final decision.

Thus, generally judge the interval interim result of determination except each is interim, also consider last final decision result and carry out current final decision, so by reliable judgement with avoided from the control of the control smooth change jumpy of last time, proceed stable air conditioning indoor, keep indoor comfort.Adaptability when on the other hand, the output of also having guaranteed interim judgement interval has obviously increased.

Therefore, can be provided at general stably and when indoor comfort is kept in control, shorten time as required, in time carry out the air conditioner of the control of air conditioner until final decision.

In addition, the air conditioner of embodiment, according to the afore mentioned rules of above-mentioned active pulse in the time the detection number of times and according to the size of the activity threshold value of zoning, divide the people's in above-mentioned existence zone the grade of size of activity, at above-mentioned detection number of times is above-mentionedly promptly to decide threshold value when following, according to above-mentioned detection number of times, to the interval grade of the size of judgement people's activity temporarily of each above-mentioned interim judgement, a plurality of interim result of determination based on afore mentioned rules, the grade of the size of final decision activity, surpass at above-mentioned detection number of times above-mentioned when promptly deciding threshold value, with the result of the interim judgement in above-mentioned interim judgement interval final decision as the grade of the size of activity.

Thus, the ability according to the size of activity increase and decrease air conditioner can improve comfortableness by energy-saving operation and control fast as required.And, generally by reliable judgement and with the control that the grade of the size of people's activity meets reposefully, keep indoor comfort, on the other hand, when the interval output of interim judgement has obviously increased,, also guarantee adaptability to the variation of indoor conditions with rapid-action control.

Therefore, activity control air conditioner according to indoor occupant can be provided, in raising that realizes comfortableness and energy-saving operation etc., generally keep indoor comfort with control stably, but shorten time as required, in time carry out the air conditioner of the control of air conditioner until final decision.

In addition, in the air conditioner of embodiment, above-mentioned infrared ray sensor is a current pyroelectric infrared sensor.

Thus, for example, at specific area illumination daylight, when perhaps having the break-make of heater, detect the temporary transient increase of output, but because infrared ray sensor is an electrothermic type, therefore catch ambient temperature immediately, need not detect, can not have false judgment is the situation that the people is arranged.

And, need not to use the sensor of the high price of thermoelectric pile and so on, so can reduce manufacturing cost.

Therefore, can provide effective opposing to disturb, and reduce the air conditioner of manufacturing cost.

Then, use Figure 39～Figure 41 that the method for final decision is described.There is the regional determination example in Figure 39, (b) is to have the sub-region right coefficient.Figure 40 is the phase judgement example of the size of activity.Figure 41 is that existence is regional, the phase judgement result's of the size of activity example.

In Figure 39, zero mark is in each interim existence zone of judging that interim judgement has been carried out in the interval, is the weighted point that this existence zone is applied in ().

The people's of the air conditioner of embodiment existence whether with exist dividing region as mentioned above for not, (1), (2), (3), (1)+(2)+(3) 5 kinds, to each interim judge the division that provides interim result of determination (be identified as the zone that has the zone or not division) point of weighting.In the example of Figure 39, the zone (1) of primary interim result of determination is applied the point of α 1, the zone (3) of secondary interim result of determination is applied the point of α 2, the zone (1) of for the third time interim result of determination is applied the point of α 3, zone (1)+(2) of the 4th time interim result of determination are applied the point of α 4, the zone (1) of the 5th time interim result of determination is applied the point of α 5 ..., the zone (1) of the N time interim result of determination is applied the point of α N.And, the final decision result's of last time zone (1) is applied the point of β.

Finish after N time the interim judgement interval of regulation, carry out to people's existence whether with the accumulative total of the point that exists each regional division to apply, the zone (1) of the summation maximum of the point that final decision applied (being 30 points in this embodiment) is current existence zone.

At this moment, if the point that will apply in each interim judgement is set at the point that only increases setting when appending number of times shown in Figure 39 (b) at every turn, then up-to-date interim result of determination is much accounted of, and reasonably carries out the control of air conditioner.

In Figure 40, zero mark is in each interim grade of judging interval and final decision for the size of the activity of the existence zone (being (1) in this embodiment) that has zone when identical, is the weighted point that the grade to the size of this activity applies in ().

Then, judge in grade as the size of the activity in the zone (1) in above-mentioned final decision result's existence zone.The grade of the size of activity is divided into three as mentioned above, and the grade of size of the activity to each interim result of determination of having the zone during for the interim judgement in zone (1) applies the point of weighting.In the example of Figure 40, to exist the zone interim result of determination for the zone (1) the first time, for the third time, the 5th time ..., the division application point of the grade of the size of the N time activity.The first time grade " little " of the size of activity is applied the point of γ 1, for the third time the grade " little " of the size of this activity is applied the point of γ 3, the 5th grade to the size of activity " in " apply the point of γ 5,, the N time grade to the size of activity " little " applies the point of γ N.Calculate the summation of the point that each division to the grade of the size of activity applies, the final summation of judging the point that is applied is " little " grade for the size of current activity for the grade of the size of the activity of maximum (being 27 points in this embodiment).

At this moment, if will similarly be set at the point that only increases setting when appending number of times during with the interim judgement that has the zone at each interim point that apply in judging at every turn, then same up-to-date interim result of determination is much accounted of, and reasonably carries out the control of air conditioner.

In Figure 41, zero is labeled as each interim judges interval existence zone of temporarily judging, " in ", the grade of the size of the activity the when literal of " little " be interim judgement, counting is the point of weighting.

Figure 41 be N=4 and each interim judge the occasion that increases a point (α 1=γ 1=1, α 2=γ 2=2 ...) the people existence whether with the example of the final decision of the grade of the size of final decision that has the zone and activity.To have the zone be zone (1) last once be 2 points, interim judging interval 1 to be 1 point, judging that interim interval 4 is 7 of 4 summations and maximum that final decision is regional (1).

The grade of the size of activity be the interim grade of judging the size of interval 4 activity " in " 4 maximums in zone (1), so final decision be the size of activity grade " in ".

At this moment, the point whether people's existence is applied with the final decision result of the last time that has the zone is set at the centre (β among the embodiment=2) of the point that current interim result of determination is applied, and then control becomes smoothly and makes things convenient for.

Then, use Figure 19, Figure 22, Figure 42, Figure 43 that near judgement in Figure 26 step S9 far away is described.Figure 42 be far away in nearly criterion.Figure 43 is cold air, the up-down wind direction board portion amplification view when heating installation turns round of indoor set.

Above-mentioned each is interim judge between the detection zone in interval for sensing chamber in whole indoor conditions, for the position of upside up-down wind direction board 291 is looked forward to from the near position～position far away of air conditioner, away from people detection sensor 140, be placed on Figure 19 upside up-down wind direction board position 491m near position probing detection range 591m the people existence whether.

In step S9, further the position of upside up-down wind direction board 291 is placed on the upside up-down wind direction board position 491j of Figure 19, position far away and the centre position of 491k, whether the people's of

detection detection range

591j, 591k existence to be.

In step S8, the final decision result closes for being absent from the scene, and is omitted in the detection action in position far away, centre position.This be because, be equivalent to nobody in the scope of position of near position～far away, also be useless even carried out the detection action of depth direction.

In step S8, be judged to be the indoor people's of having occasion, upside up-down wind direction board 291 is rotated and detects action to position far away.Arrive people's occasion with the detection motion detection of position far away, judging has the people in the distance, is omitted in the detection action in next centre position.

This be because, use in refrigeration system is in carrying out air conditioning to indoor, the occasion that the people is arranged in the distance, for the people who satisfies this distant place carries out air conditioning, need carry out wind arrival air conditioning afield, thus, becoming centre or near people does not roughly have discontented air conditioning yet, so middle or near whether have the people all to become identical control, therefore can omit the detection action in next centre position.

Do not detect people's occasion with the detection of position far away action, carry out detection action in the centre position.Arrive people's occasion with the detection motion detection in centre position, judging has the people in the centre, and in the occasion that does not detect the people with the detection action in centre position, judging has the people nearby.

With above-mentioned final judgement underdraw then become shown in Figure 42, position probing far away at upside up-down wind direction board 291 judges that to people's occasion the people is positioned at position far away, the occasion that does not detect the people in position far away and detect the people in the centre position judges that the people is positioned at the centre position, and the occasion that does not all detect the people in position far away and centre position judges that the people is positioned near position.

Far away～near final judgement according to the people position is arranged is controlled to suitable intensity, direction with indoor Air Blast fan 311 and up-down wind direction board 291,292 etc.

In addition, cold air, when running dehumidifying generally make upside up-down wind direction board 291 as shown in figure 43 with upper wall 290a that blows out air channel 290 and lower wall 290b almost parallel.This occasion needs upside up-down wind direction board 291 is descended as shown in figure 22 in people's the detection action, thus change of the wind up and down.In an embodiment, in order to reduce this influence, interim judgement length of an interval degree 5 minutes 30 seconds have been shortened with the length between detection zone (=stipulated time).With in 30 seconds short time since the freeze cycle of air conditioner its possess thermal capacitance, therefore can't see big variation, also little to the variation of indoor cold air, dehumidifying effect.And, by also little with the influence to indoor temperature of the thermal balance of extraneous gas decision, in the occasion of the air conditioner of the ability changeable type that increases in recent years, cold air, dehumidifying effect are compensated according to heat load, so the influence to indoor temperature does not exist, and has kept comfortableness.

On the other hand, wind direction multilated in the meantime up and down, thus indoor occupant is brought some influences, but because the time is short, therefore be and the equal following lighter variation of swing control of the automatic wind direction board that generally carries out can not hinder comfortableness.And the time beyond temporarily judging between the detection zone in the interval is to the restriction of the position of upside up-down wind direction board 291, so can also or make its automatic swing towards direction arbitrarily, can not damage convenience.

Like this, in the air conditioner of embodiment, above-mentioned Air Blast fan is the Air Blast fan of cross-flow type, above-mentioned left and right sides wind direction board, at least one wind direction board of any wind direction board in the up-down wind direction board constitutes the shield that can rotate and become above-mentioned infrared ray sensor around the axle with the axle almost parallel of above-mentioned Air Blast fan, the major part of above-mentioned shield above-mentioned zone in the hidden compartment when running stops, and in the existence that detects indoor occupant whether or when having the zone, rotate interimly, and cover above-mentioned zone with a plurality of stages, above-mentioned zone further is divided into a plurality of segmentations zone.

Thus, except dividing region (for example division of left and right directions) according to above-mentioned a plurality of people detection sensors, can also go up in vertical therewith direction (for example depth direction) and divide, detect the position of indoor occupant in more detail, can be according to the wind direction of this Position Control air conditioner, air quantity, cold air heating installation ability etc.

And, as shown in Figure 2, upside up-down wind direction board, downside up-down wind direction board, moveable panel are closed the air blow-off outlet by control device, so the infrared ray sensor crested when the running of not using air conditioner stops, can't see from indoor, can not upset indoor atmosphere.

In addition,, the shield of upside up-down wind direction board as the visual field of dividing infrared ray sensor used, thereby do not need special-purpose means for screening, shield drive division, saved resource, can reduce weight, cost in order to detect the position of indoor occupant.

Therefore, can not provide and can upset indoor atmosphere, be suitable for saving resource, further in the fractionizing chamber, realize the air conditioner of good air conditioning according to the position of indoor occupant.

In addition, the air conditioner of present embodiment possesses the Air Blast fan of the cross-flow type of growing crosswise on the cabinet of growing crosswise, above-mentioned a plurality of infrared ray sensors are arranged to the direction expansion to the left and right of its central shaft, the wind direction board that will become above-mentioned shield is as up-down wind direction board, the rotation of the stage by above-mentioned up-down wind direction board, cover above-mentioned zone with a plurality of stages, above-mentioned zone is divided into a plurality of segmentations zone of territory, far field near field.

Thus, the visual field of infrared ray sensor can be covered with the upside up-down wind direction board interimly and segment the far and near position of indoor occupant and detect, not need special-purpose means for screening, shield drive division, save resource.

Therefore, in the air conditioner of the many shapes of growing crosswise of quantity, can provide and utilize the driving mechanism of upside up-down wind direction board to segment surveyed area, and realize the air conditioner of good air conditioning according to the position of indoor occupant with low cost.

In addition, the air conditioner of embodiment according to above-mentioned people's existence whether with the final decision result of the grade of the size of the people's in final decision result who has the zone and above-mentioned existence zone activity, at least more than one of control compressor, refrigerant loop control device, Air Blast fan, left and right sides wind direction board, up-down wind direction board or display unit.

Thus, state increase and decrease cold air according to indoor occupant, the ability of heating installation etc., the temperature of change dehumidifying is set, at the state continuance that does not have indoor occupant during the stipulated time, change to the temperature setting energy-conservation, the people not state stop air conditioner when continuing, emphasis ground carries out an air-conditioning to there being the zone, avoid having the zone and blowing, improve the ability of air-conditioning, the intensity that increase and decrease is blown etc., just can carry out using the control of carrying out on the basis of air conditioner to need not the trouble staff usually, and, can automatically change according to the variation of these operating conditions and show and to inform etc., become the good air conditioner of convenience.

Therefore, can provide state, carry out the air conditioner of comfortable running and energy-saving operation automatically according to indoor occupant.

In addition, the air conditioner of embodiment has control device, whether this control device lacks with the interim judgement that has the zone at interval than above-mentioned people's existence if carrying out the stipulated time of the detection of above-mentioned active pulse, and the time beyond the stipulated time of the detection of carrying out above-mentioned active pulse becomes the swing of the up-down wind direction board of above-mentioned shield.

Thus, the up-down wind direction board that will become shield in cold air, when running dehumidifying etc. is when the position in the visual field that can cover infrared ray sensor, above-mentioned up-down wind direction board is finished with the short time towards the detection action of the position that is not suitable for cold air, dehumidifying running, and the most of the time can make up-down wind direction board towards suitable position.

This occasion is judged interval result owing to will judge the interval testing result of a part in the interval temporarily as interim, the danger of the state in interim judgement interval therefore also may occur accurately reflecting.But, set a plurality of interim judgements interval as mentioned above, the result of the interim judgement in comprehensive this a plurality of interim judgements interval is as final decision, therefore by suitably select interim judge length of an interval degree and number of times, can roughly reflect exactly to judge interval state in final decision.

This is because as mentioned above, in the occasion of keeping indoor comfort with air conditioner, if the frequent state that changes air conditioner, then control is unstable, often brings unhappiness to indoor occupant, so must avoid the change in the control of short time interval.

In addition, people's activity has ripple, kind (see TV, reading, clean, cook, speak, do callisthenics, play table tennis, stand, take one's seat, walk etc.) according to action, the size that has activity roughly, according to the kind of these action, the heat load calculating according to indoor occupant of carrying out air conditioner is well-known.

When indoor people does certain action, be applicable to kind some of these action, even but the kind of these action (for example partly changes, the people who stands sits about 20 seconds (seldom during) and stands up immediately afterwards), continuing the kind of main action on the whole, for example, per 5 minutes, the situation that changes the kind of action busily of see TV, reading, cleaning, playing table tennis and so on was impossible.

The time that the kind of main action continues is to be a standard more than 20 minutes, becomes the sensation of so-called regional boundary limit.Like this, to judge that the interval was made as more than the time (being 20 minutes in an embodiment) of regional boundary limit, interval being made as the busy time below (being 5 minutes in an embodiment) will be judged temporarily, with be made as between detection zone very little during more than (being 30 seconds in an embodiment), thereby in final decision, can roughly reflect exactly and judge interval state.

Therefore, can be provided at when carrying out the people detection action, when cold air, dehumidifying running, also keep the air conditioner of indoor comfort level.

Then, use Figure 44 to exist regional resume to describe to the past of step S10.Figure 44 is the criterion of existence zone resume in the past, is the example of the past data of accumulation (a), (b) is the example that the order in people zone is arranged.

In step S10, accumulate the up-to-date final decision result who repeatedly has the zone, to accumulate number of times to there being the area marking order.This is shown in Figure 44 (a), after when each output exists regional final decision as a result, there are the data the earliest of regional final decision result's accumulation data in cancellation repeatedly (being 255 times in an embodiment) in the past, appends current final decision result and upgrades.And, shown in Figure 44 (b), exist regional calculated product time and again to count to each, exist the order in zone to mark with the accumulation number of times, the maximum existence zone of accumulation number of times is made as No. 1.At this moment, this regional characteristic can be described as " place that the people is always arranged ".The existence zone of accumulation least number of times is made as No. 4, and its characteristic can be described as " no one's place always ".

Thus, can know place that the people is always arranged and no one's place always, when entry into service on time, even without the people, can carry out automatically to the highest place air-supply of existence order, perhaps under the situation of avoiding wind directly to blow to running except the low place air-supply of the existence order in place that the people is arranged now, thereby do not bother.

Then, use Figure 45～Figure 47 that the application examples of people detection is described.Figure 45 is the variation order of wind direction.Figure 46 is based on the Energy Saving Control of grade of the size of activity.Figure 47 is the example of air supply direction, (a) is the left comer air-supply, (b) is the right corner air-supply, (c) is positive air-supply, (d) is the wide region air-supply.

In Figure 45, utilize the people detection result, carry out alternate repetition and make wind towards the running of the some air conditioner type of the direction that the people is arranged with wind is transported to the control of operation of air conditioner of room integral body of the wide region in room.

This is because at the beginning of the non-conditioned space from the outside entered the room, response wanted to concentrate the demand that blows to cold wind, warm wind.

At this moment, the time set of accepting wind must be shorter, so want to prolong the occasion of the time of blowing, waits by waving to air conditioner and carry out bigger action, can prolong the time of blowing with the final decision in the existence zone of having omitted above-mentioned interim judgement interval.In contrast, must be longer if will accept the time set of wind, then fully blown to wind, even so want to get back to the air-conditioning of room integral body, move if escape wind, move and wind is caught up with can not escape thereby then detect, can only remote controller change wind direction, perhaps do not restrain oneself and the stand-by period process with moving at all, use inconvenient.

In addition, replace wide region air-supply, also can make the direction of wind beyond the direction that the people is arranged the room.This occasion, as the direction beyond the direction that the people is arranged, near the existence zone that the people is arranged, make wind towards the low zone of above-mentioned existence order, then accept indirectly towards the wind of near zone be involved in and with the soft wind such as reflection of the wind of wall collision, when directly not accepting wind, also can continue comfortableness.

In Figure 46, utilize the result of grade of the size of activity, carry out energy-saving operation automatically according to the grade of the size of activity, thus the control balance comfortableness and energy-conservation running.

This following carrying out, set the occasion of the running of energy saver mode the user, grade according to the size of the activity of indoor occupant, change indoor design temperature, set humidity and realize energy-conservation, the big more design temperature (maximum in an embodiment 2 degree that descend) that reduces more of the order of magnitude of activity during the heating installation running, during cold air operation the grade of the size of activity more minor change turn round for high more (in an embodiment maximum improve 2 degree), more little the raising more of the grade of the size of activity set humidity (maximum in an embodiment improve 15%) and turns round during dehumidifying.

Thus, during the heating installation running, the caloric value of the many more human bodies of activity is just many more, is arranged to lower room temperature more, and the caloric value of the few more human body of activity is just few more, reduces the amplitude that reduces room temperature and obtains energy-conservation and balance comfortableness.During cold air operation, the caloric value of the few more human body of activity is just few more, is set at higher temperature more, and the caloric value of the many more human bodies of activity is just many more, reduces the amplitude that improves room temperature and obtains energy-conservation and balance comfortableness.During the dehumidifying running, the caloric value of the few more human body of activity is just few more, is set at higher humidity more, and the caloric value of the many more human bodies of activity is just many more, and the amplitude of the humidity that reduces to improve obtains energy-conservation and balance comfortableness.

In addition, in the step S6 of Figure 26, as continue not situation under carry out do not control at energy-saving operation, when turning round, heating installation carries out control according to the grade of the size of the activity of maximum, carry out control in cold air, when running dehumidifying according to the grade of the size of the activity of minimum, treat air conditioner during then as long the leaving a banquet or a meeting of indoor occupant, be fit to energy-conservation, when indoor occupant returns, can from treat air conditioner with the short time with the indoor comfortable space that becomes, can not damage the satisfaction of indoor occupant.

In an embodiment, time (second stipulated time) has not continued 20 minutes occasion, carries out this and does not control at energy-saving operation.

Figure 47 represents the example of the wind direction when the indoor set 2 of occasion of wind direction is changed in last observation according to the final decision result who has the zone, for example, wind direction is controlled left and right sides wind direction board 295 towards the occasion in zone (1) shown in Figure 47 (a), zone (2) is shown in (b), zone (3) is shown in (c), and left and right sides wind direction board 295 is controlled in (1)+(2)+(3), zone shown in (d).

In addition, if the value of using in the above description that has threshold value, promptly decides

threshold value

1,2,

activity threshold value

1,2 can change with the special operational of remote controller 5, then want more energy-conservation running having, perhaps to pay attention to the more occasion of the user's of comfortableness purpose, can change the value of these threshold values, purpose according to the user is regulated the responsiveness of controlling, can energy-conservation or raising satisfaction.

And, this threshold value is stored in removably in the storage device, the change of threshold value is carried out with more bringing of storage device removably, also can have identical effect.This occasion is not limited to the change of threshold value, can certainly carry out the change of the control of corresponding multiple environment.

Like this, the air conditioning apparatus of embodiment becomes to change and above-mentionedly has threshold value, promptly decides threshold value, activity threshold value.

Thus, for example, these threshold values are stored in storage device removably maybe can be from the storage device that operating portion upgrades, by the removably replacing of storage device or the above-mentioned threshold value of change of more newly arriving of renewable storage device.By like this, want more energy-conservation running having, perhaps to pay attention to the more occasion of the user's of comfortableness purpose, perhaps the general house with family compares, what, the aspect ratio in room, the configuration of furniture, the differences such as length of service time of the size in room, indoor occupant, the occasion that it is special that thereby the type of service of air conditioner becomes can change above-mentioned threshold value.If the value of above-mentioned threshold value is changed to bigger, detection sensitivity dull then, the frequent running change of air conditioner is suppressed, if the value of above-mentioned threshold value is changed to less, then detection sensitivity becomes sharp, the frequency of the running change of air conditioner increases.

Therefore, can provide the responsiveness of regulating control according to the purpose that environment and user are set of air conditioner, and air conditioner energy-conservation or the raising satisfaction.
