Below, with reference to accompanying drawing embodiment of the present invention is described.In addition, the present invention is not limited by this embodiment.

(embodiment 1)

Fig. 1 is the isometric front view of indoor unit of the air conditioner of this embodiment, and Fig. 2 is the longitudinal section of indoor unit 1.As depicted in figs. 1 and 2, indoor unit 1 possesses room air and cold-producing medium carry out heat exchange in inside indoor heat converter 2, in the inboard of the indoor heat converter 2 of V-shape roughly, has heating or cooled air are sent to indoor indoor blower 3.

In addition; Blow-off outlet at indoor unit 1 has left and right sides wind direction blade 4 (in this embodiment; Be first left and right sides wind direction blade 4A and second left and right sides wind direction blade 4B); 4 pairs of this left and right sides wind direction blades change with the blow-off direction of the wind that indoor blower 3 blows out at left and right directions, move at left and right directions independently respectively.In addition, have wind direction blade up and down 5 at above-below direction change blow-off direction (in this embodiment, being wind direction blade 5A and second wind direction blade 5B up and down first about), distinguish and move at above-below direction independently at the blow-off outlet of indoor unit 1.

In addition, on the top of blow-off outlet, the human body detection sensor unit 6 of detection infrared ray variation is arranged in the framework internal configurations of indoor unit 1.

Fig. 3 is the structure chart of human body detection sensor unit 6.Among Fig. 3; The human body detection sensor unit of this embodiment has: detect by the infrared ray in zone, the distant place in air conditioning zone (indoor) change remote use human body detection sensor 7A and detect near zone the infrared ray variation closely use human body detection sensor 7B.In addition; In this embodiment; Though have at a distance with human body detection sensor 7A with closely use human body detection sensor 7B, be not limited thereto, if the little air conditioner of ability rating; Owing to do not imagine the air conditioning of big room, constitute with human body detection sensor 7B so can only be provided with closely yet.

And, have with at a distance with human body detection sensor 7A and the stepper motor 8 that closely synchronously on same direction, drives with human body detection sensor 7B, be used to transmit the rotation of stepper motor 8 drive link 9A, be used for the rotation via the stepper motor 8 of drive link transmission is delivered to remote with human body detection sensor 7A with closely use the binding lever arm 9B of human body detection sensor 7B.

And; Through linking the effect of lever arm 9B; Remote with human body detection sensor 7A with closely rotate with same amount with respect to the rotation of stepper motor 8 with human body detection sensor 7B, thus can make remote with human body detection sensor 7A with closely use the human body detection sensor 7B while towards identical left and right directions.

In addition; As shown in Figure 1; Human body detection sensor unit 6 is arranged at the blow-off outlet top of the wind that is blown out by indoor blower 3, adopts at a distance the mounting structure that erroneous detection takes place with human body detection sensor 7A and the heating that closely can reason indoor blower 3 blow out with human body detection sensor 7B or cooled air.For example,, then can receive the influence of this wind, erroneous detection takes place if be arranged at the position that warm wind and cold wind directly blow to.

Particularly, when air conditioner stopped, front panel was closed, and became the structure that the human body detection sensor unit hides; When air-conditioner operation, front panel is opened, and becomes the structure that the human body detection sensor unit manifests.Therefore design is good, in addition, owing to do not need on the plate human body detection sensor unit to be installed in front, so the wiring of the lead of drawing from the human body detection sensor unit etc. is also easy.In addition, Fig. 1 is the stereogram of the state opened of expression front panel.

Then, the control to the human detection of this embodiment describes.

At first, the way of thinking from the air conditioning zone begins explanation.Fig. 4 (a) be expression at a distance with the sketch map of the detection angles of human body detection sensor 7A, Fig. 4 (b) is a sketch map of representing closely to use the detection angles of human body detection sensor 7B.Shown in Fig. 4 (a) and Fig. 4 (b), in this embodiment, the detection angles with human body detection sensor 7A is made as 35 degree at a distance, and can detect with indoor unit 1 is the zone of center from about 3m degree to the degree that surpasses about 10m.In addition, closely the detection angles with human body detection sensor 7B is made as 55 degree, can detect from indoor unit 1 to the zone of leaving about 5m degree.In addition, above-mentioned surveyed area is not limited to above-mentioned numerical value, can suitably change, also can be different by the installation site (short transverse) of indoor unit 1.

In addition; In this embodiment; Owing to be provided with remote with human body detection sensor 7A with closely use two sensors of human body detection sensor 7B; So establish can be only with the n zone of doing, the field of closely detecting with human body detection sensor 7B, establishing can be with remote with human body detection sensor 7A and the field of closely detecting with the human body detection sensor 7B m zone of doing, and establishes and can only use the remote f zone of doing with human body detection sensor 7A detection.In addition, in this embodiment, be provided with two human body detection sensors and it is disposed at left and right directions, but be not limited thereto, it is also no problem to be disposed at above-below direction or incline direction.

Fig. 5 is that expression can be with the figure in the zone of two human body detection sensors detections.As shown in Figure 5, as stated, can be divided into n zone, m zone, regional three zones of f to depth direction from indoor unit 1.In this embodiment, nearly distance domain is called the n zone, and the middle distance territory is called the m zone, and the long distance delocalization is called the f zone.In addition, as shown in Figure 5, on left and right directions, be divided into nine bigger zones, be made as a-quadrant～I zone.

Promptly; Since to one indoor, on depth direction, carry out three and cut apart, on left and right directions, carry out nine and cut apart; So at length be divided into the air conditioning zone in 27 zones; Be divided into An zone～In zone in the low coverage delocalization, be divided into Am zone～Im zone in the middle distance territory, be divided into the zone in Af zone～If zone in the long distance delocalization.

Then, to confirming that based on human body detection sensor the method for human body describes in above-mentioned air conditioning zone.Fig. 6 is that expression begins to the figure based on a series of flow processs till the air conditioning of human detection from running.In addition; In this embodiment,, be recited as human body detection sensor 7 with human body detection sensor 7 this expression methods; Thus under the situation of the indoor unit of big ability type; Refer at a distance with human body detection sensor 7A with closely use human body detection sensor 7B both sides, under the situation of the indoor unit of little ability type, only refer to closely use human body detection sensor 7B.

At first, with Fig. 6 the action of the indoor unit 1 of this embodiment is described.As shown in Figure 6; When utilizing remote controller etc. when indoor unit 1 sends the indication of beginning air conditioning running; At first in step SP1; Implement scan pattern, this scan pattern from left end to the right end (or from right-hand end end) to the left with the actuating speed driving person body detecting sensor 7 of regulation, detect the position that is present in indoor thermal source.At this moment, do not carry out the difference between the thermal source beyond human body and the human body as yet, just in the position of confirming thermal source.In addition, the scan pattern of this embodiment is the pattern that drives to confirm thermal source at left and right directions.

Then; For detected thermal source in the scan pattern to step SP1 differentiate whether be beyond human body or the human body thermal source (for example; Furniture and TV etc.), with respect to thermal source fixing human detecting sensor 7 towards, move to and judge it is the fixed mode of the thermal source beyond human body or the human body.At this moment; Detected thermal source is under a plurality of situation in scan pattern; For any one thermal source, all at first through whether moving to fixed mode permanent order decision (step SP2) and fix set time how long decision (step SP3) with respect to this thermal source; Then in step SP4, at the fixed mode thermal source beyond human body and the human body that judges.

Then, confirmed that under fixed mode thermal source is that based on this human detection result, which air conditioning zone judgement should carry out air conditioning to after the thermal source beyond human body or the human body, the line space of going forward side by side controlled atmosphere joint (step SP5).Then, in step SP6, send the indication that running stops to indoor unit 1 with remote controller etc.; Perhaps with the timer setting-up time when official hour to the time; The running of indoor unit 1 stops automatically, and the running of indoor unit 1 is stopped, but under the situation of the running that continues indoor unit 1; Return step SP1, under scan pattern, detect thermal source once more.Like this, stop, carrying out scan pattern and fixed mode repeatedly, can correctly detect constantly all in the indoor situation that changes thus and inform air conditioning, regulate environment so can realize optimal air up to the running of indoor unit 1.

Then, each step shown in Figure 6 is elaborated.

Fig. 7 is the figure of the cut zone of expression human body detection sensor 7 scan pattern of confirming heat source positions.In Fig. 5, the air conditioning zone is divided into 27 zones, but the thermal source of scan pattern confirms the cut zone of position and on left and right directions, cuts apart 25 zones, confirm heat source position carefully.After, in this manual, the zone that 25 of A0～I1 is cut apart is called the zonule, does not carry out the difference of low coverage delocalization, middle distance territory, long distance delocalization.In addition, the zonule is corresponding with the air conditioning zone, and A0 and A1 cover An～Af zone; Below, B0～B2 covers Bn～Bf zone, and C0～C2 covers Cn～Cf zone; D0～D2 covers Dn～Df zone, and E0～E2 covers En～Ef zone, and F0～F2 covers Fn～Ff zone; G0～G2 covers Gn～Gf zone, and H0～H2 covers Hn～Hf zone, and I0～I1 covers In～If zone.

Shown in Figure 7 from the zonule of A0～I1 and the pulse position interlock of stepper motor 8, the peak width of each zonule A0～I1 (that is the pulse width of stepper motor 8) about equally.But, make the half the pulse width of the zonule at A0 and these both ends of I1 for another zonule.In this embodiment, zonule A0 is corresponding to 1 pulse～25 pulses of stepper motor, and zonule A1 is corresponding to 26 pulses～75 pulses ... (centre all is zonules of per 50 pulse shapings) ..., zonule I1 is made as 1176 pulses～1200 pulses.

The netting twine of Fig. 7 partly is a part of conceptually representing the surveyed area of human body detection sensor.At first, when sending the indication of air conditioning running beginning to indoor unit 1, through the driving of stepper motor 8, human body detection sensor 7 drives at left and right directions with fixing speed Vd.In this embodiment, initial fixing speed Vd is made as 2deg/sec.Then, human body detection sensor 7 is driven into right-hand end ZR (perhaps, from right-hand end ZR to left end ZL) from left end ZL.In addition, driving direction during according to the last scan pattern human body detection sensor 7 which direction to stop the starting point that the end of the side that human body detection sensor 7 is stopped to drive as the human body detection sensor 7 of next scan pattern in.But the scanning direction that makes primary air regulate the scan pattern of running is a direction.That is, the fixed mode of stating after after scan pattern, moving to moves under the situation of scan pattern again, make it with the scanning direction of scan pattern for the first time be same direction.

Then, till arrive right-hand end ZR, detect ultrared change, when the output valve of human body detection sensor surpasses certain certain threshold value Vpp (for example, 1 [V]), be judged as and have (suitable) thermal source with human body with human body detection sensor 7 from left end ZL.The pulse position interlock of the judgement of this thermal source and stepper motor 8, every driving one pulse, what all judge thermal source is denying.

Then, stepper motor 8 every action one pulses judge that all thermal source in the result who denys is, all exist under the situation of thermal source in the above pulse position of setting (for example, three times) being judged to be every zonule, are judged to be in this zonule to have thermal source.In addition, setting is not limited to three times, also can suitably change according to the style of human body detection sensor and the structure of system.

In addition, all only exist under the situation of thermal source being judged as each zonule, be judged to be and do not have thermal source in this zonule in the pulse position of not enough setting.This is because human body detection sensor 7 might detect noise or compare very little thermal source with human body.

For example, the zonule with A1 is that example describes.Be under 4 times the situation at the number of times that stepper motor 8 uses during 26 pulse to 75 pulse actions human body detection sensor 7 to detect certain infrared ray change more than certain threshold value Vpp; Owing to surpassed setting (at this; Be made as 3 times), there is thermal source in A1 in the zonule so be judged to be.But the number of times that during human body detection sensor 7 detects A1, detects the infrared ray change is under 2 times the situation, to be judged as not enough setting, is judged to be zonule A1 and does not have thermal source.

When this scan pattern, take place sometimes excessively to detect thermal source, or detect the situation of thermal source hardly.The human body detection sensor 7 of this embodiment record is to use burnt electric type infrared ray sensor to detect the sensor of the infrared ray quantitative changeization (temperature change) of institute's radiation.Under the situation of using the electric type infrared ray sensor of this Jiao; Can think owing to the situation of situation about almost not had by the temperature difference between the zone of air conditioning and the thermal source, the distance from the human body detection sensor to the thermal source, cause output valve to produce the situation of difference because of the deviation of the making of human body detection sensor self; The deteriorations of human body detection sensor self etc. cause having taken place aforesaid problem.

So, in this embodiment, (for example be judged to be not enough certain the certain number N1 in the zonule that has thermal source; 5) time, be judged as and do not detect human body, the speed Vd of the making certain speed that only rises; Once more at left and right directions driving person body detecting sensor 7 (for example, in this embodiment, because initial velocity is made as Vd=2deg/sec; So make it the 0.5deg/sec that rises, be Vd=2.5deg/sec).

And even under scan pattern, carrying out the thermal source judgement once more, the number of the thermal source in the zonule does not reach under the situation of a certain number of N1 yet, and the speed Vd of the making certain speed that further rises further continues scan pattern.Like this, up to being judged to be till the zonule that has thermal source reaches a certain number of N1, all continue scan pattern.

But,, (for example, 4deg/sec), the speed that surpasses the upper limit is not implemented to quicken so speed Vd is provided with the upper limit owing to there is the situation of in fact unsuitable thermal source with human body yet.In addition, this higher limit is not limited to above-mentioned value, so long as the speed of the degree that under the condition that is difficult to most detect human body (to the situation of the distance of thermal source and thermal source and temperature difference on every side little situation etc.), also can detect is just no problem.

On the other hand, be judged to be have thermal source the zonule when certain certain number N2 is above, be judged as the thermal source that has detected beyond a plurality of human bodies; The speed Vd of making reduces certain speed; Once more at left and right directions driving person body detecting sensor 7 (for example, in this embodiment, because initial velocity is made as Vd=2deg/sec; So make it to reduce 0.5deg/sec, be Vd=1.5deg/sec).

And even under scan pattern, carrying out the thermal source judgement once more, also under the situation more than a certain number of N2, the speed Vd of making further reduces certain speed to the number of the thermal source in the zonule, further continues scan pattern.Like this, till being judged to be the not enough a certain number of N2 in the zonule that has thermal source, all continue scan pattern.

But, also consider in fact to have many thermals source, and all detect the situation of thermal source in many zones of zonule.So, speed Vd is provided with lower limit (for example, 1deg/sec), the speed that is lower than lower limit is not implemented to slow down.In addition, this lower limit is not limited to above-mentioned, so long as the speed of the degree that under the condition that detects human body the most easily, can detect is just no problem.

As stated, in this embodiment,, can detect correct heat source position through this threshold value of N1 and N2 is set.This is because the burnt electric type infrared ray sensor that this embodiment adopts on human body detection sensor 7 has following tendency,, in the time will detecting the thermal source suitable with human body, rises to a certain constant speed degree through making actuating speed that is, makes output valve raise; Through making actuating speed be reduced to a certain constant speed degree, make output valve reduce, through this character is additional to human detection, can correctly confirm the thermal source suitable with human body.

In addition, under scan pattern, the limit makes the actuating speed acceleration and deceleration of human body detection sensor 7; Confirming of heat source position carried out on the limit, through the actuating speed of human body detection sensor 7 is quickened, makes the position of thermal source become more than a certain number of N2; Consequently; When the actuating speed of human body detection sensor 7 was slowed down, current thermal source is the not enough a certain number of N1 of allocation really, and the actuating speed of human body detection sensor 7 is quickened.In this case, can cause being absorbed in the situation of acceleration and the deceleration of carrying out human body detection sensor 7 repeatedly, scan pattern does not finish, and definite problem that does not finish always of thermal source occurs.

So, in this embodiment, the number of times of scan pattern is provided with the upper limit (for example, 7 times), forcibly finish scan pattern.Owing to the upper limit number of times of this moment be for limit scan pattern carry out repeatedly be provided with, so can set according to suitable situation, for example; Through setting from the lower limit speed to the upper limit speed; Perhaps the number of times from the upper limit speed to the lower limit speed can positively carry out thermal source scanning and (in this embodiment, lower limit speed is made as 1deg/sec; Upper limit speed is made as 4deg/sec; Acceleration-deceleration is made as 0.5deg/sec,, just can under all actuating speeds, carries out scan pattern) so the upper limit number of times that needs only scan pattern is set at 7 times.

In addition, consider following situation, promptly; Under scan pattern, detect thermal source up to human body detection sensor, output valve surpasses certain threshold value Vpp; Judge and confirm as to exist till the thermal source, need spended time, on the pulse position of reality and the position of having confirmed thermal source, can produce deviation.For example, detected data when existing stepper motor 8 to be positioned at the position of 10 pulses, situation about when stepper motor 8 reaches the position of 40 pulses, being obtained as heat source position.In this case, because actual heat source position is the data of stepper motor 8 when 10 pulses, so will obtain proper data revising the pulse value of regulation in the opposite direction with driven square.

So; In this embodiment; In order to revise actual pulse position and to have confirmed the deviation between the position of thermal source, beginning under the scan condition direction left from left end ZL, beginning under the scan condition direction to the right from right-hand end ZR; With the position of the result of determination certain pulse value (for example 30 pulses) that staggers, make heat source position roughly consistent with pulse position.This moment, the pulse value (in above-mentioned, being made as 30 pulses) that staggers also can be variable according to temperature conditions etc., can change to suitable situation to be worth accordingly.

More than the scan pattern of step SP1 shown in Figure 6 is illustrated.Then, step SP2 is described.

When under the scan pattern of step SP1, having confirmed whether thermal source to be arranged in the zonule, then in order to judge that whether thermal source is human body, moves to fixed mode.But, at step SP1, detect the situation of a plurality of thermals source owing to exist, whether be human body so will confirm to judge in fixed mode successively from which thermal source.In addition, the fixed mode of this embodiment is the pattern that fixing human detecting sensor 7 is confirmed thermal source.Below, fixed mode is described, in fixed mode, with the way of thinking of the regional block of air conditioning.

Fig. 8 is the figure that the air conditioning zone is divided into three blocks.At first the definition to block describes.As shown in Figure 8,27 zones shown in Figure 5 (about 9 directions) is divided into three blocks.That is, An～Af, Bn～Bf, Cn～Cf zone are made as block L, Dn～Df, En～Ef, Fn～Ff zone are made as block C, Gn～Gf, Hn～Hf, In～If zone are made as block R.

In this embodiment; Under scan pattern, confirmed the thermal source of 25 directions, still; Although the whole thermal source of 25 directions is not judged whether it is human body; But since the air conditioning zone also be about 9 directions, in view of must to make the time of confirming human body be the short time, as long as the fixed mode of enforcement 9 directions.

In addition, in this embodiment, compare, preferentially confirm the order of block with the position of thermal source.Its reason is; Under scan pattern, detect under the situation of a plurality of thermals source; Then when confirming the fixed mode precedence of a plurality of thermals source,, will always not carry out the human body of another block is judged if the thermal source of same block always is in higher level's precedence; In another block, man-hour is arranged, bring unplessantness displeasure can for the people who is positioned at this block.

As shown in Figure 5, in this embodiment, the air conditioning zone is split into 27 zones.And 27 zones are divided into life zone (zone that the people is often arranged), moving area (zone that the people moves), non-life zone (nobody's zone basically) three zones.Which zone that 27 zones are equivalent in these three zones judges based on the testing result of human body detection sensor 7, but because when the initial start-up of indoor unit 1 etc., do not detect fully, so it is regional that Zone Full is set at non-life.

In addition, the way of thinking to life frequency describes.In each contained zone,, be made as the highest block of life frequency as long as there is a zone to exist under the situation in life zone as three regional blocks of air conditioning.In addition, in each contained zone of three blocks, life zone does not also exist but exists under the situation of moving area, is made as the high block of life frequency second.In addition, in each contained zone of three blocks, the regional moving area of living all is under the also non-existent situation, is made as non-life block, is made as the minimum block of life frequency.

Fig. 9 is the flow chart of the order decision of expression block.At first the order decision to block describes.

In the step SP11 of Fig. 9, judge whether life frequency is different in each of three blocks, and under the whole condition of different of the life frequency of three blocks, SP27 advances to step.In three blocks, exist under the situation of the identical block of life frequency, SP12 advances to step.For example, when block L is the minimum block of life frequency for the highest block of life frequency, block C for life frequency second high block, the block R, advance to SP27.

In step SP12, the life frequency of three blocks is compared, when the life frequency of two blocks was identical in three blocks, SP20 advanced to step, and when all the life frequency of blocks was all identical in three blocks, SP13 advanced to step.For example, when block L was the high block of life frequency second for the highest block of life frequency, block C for the highest block of life frequency, block R, SP20 advanced to step.

In step SP13; Whether the counting of the judgement thermal source that every drive stepping motor 8 one pulse detection arrive under scan pattern is all different at three blocks; The counting of thermal source is not all not simultaneously in whole blocks; SP19 advances to step, if the counting of two thermals source is identical in three blocks, then advances to step SP14.

In step SP14, if in three blocks all in the blocks counting of thermal source all identical, then advance to step SP15, as long as the counting of thermal source have one with another block not simultaneously, SP16 advances to step.

In step SP15, because life frequency is all identical in whole blocks, and the counting of thermal source is also identical, is that first, block R are that second, block L are the 3rd so the precedence between each block during with fixed mode is made as block C.Though in this case; Because condition all equates in whole blocks; So when ranking time no matter which kind of precedence can, but of this embodiment, be first through keeping block C; Because at first the block in the regional middle of air conditioning begins to judge whether thermal source is human body most; Even so on another block, human body is arranged, also can the unplessantness displeasure to the human body of another block be suppressed to Min. (if all have under people's the situation at block R, block C, each block of block L, is first if keep block R or block L; It is just little to the air conditioning effect of the block of opposition side then to clip block C, bigger to the influence degree of the unplessantness displeasure of human body).

In step SP16, the counting of the thermal source of two blocks is identical in the counting of the thermal source of each block, and under the situation of the counting of the thermal source of a block less than the counting of the thermal source of other two blocks, SP17 advances to step.In addition, identical at the counting of the thermal source of two blocks, and under the situation of the counting of the thermal source of a block greater than the counting of the thermal source of other two blocks, SP18 advances to step.

In step SP17; Because the counting of two blocks is greater than the counting of another block; So first and deputy ranking, are carried out in the ranking of two blocks according to the rule of block C (first)＜block R (second)＜block L (the 3rd), another block is come the 3rd.For example, identical with block C at block L at the counting of thermal source, and the counting of the thermal source of block R is lower than under the situation of another block, becoming block C and be first, block L and be second, block R is tertiary precedence.

In step SP18; Because the counting of two blocks is less than the counting of another block; So the maximum block of counting is first, the ranking of two blocks of number is carried out second and tertiary ranking according to the rule of block C (first)＜block R (second)＜block L (the 3rd) together.For example, identical with block C at block L at the counting of thermal source, and the counting of the thermal source of block R is during greater than another block, becoming block R and be first, block C and be second, block L is tertiary ranking.

In step SP19, because the counting of thermal source is all different in whole blocks, so, determine the precedence of each block according to the counting of thermal source.For example, at the counting of the thermal source of the counting maximum of the thermal source of block R and block C hour, becoming block R and be first, block L and be second, block C is tertiary ranking.

In step SP20; Only have a block that life frequency is different, but this only different block be lower than under the situation of the life frequency of two blocks in addition, SP21 advances to step; Be higher than under the situation of the life frequency of two blocks in addition, SP24 advances to step.For example, be the highest block of life frequency at block R and block C, and under the situation of block L for the minimum block of life frequency; SP21 advances to step; At block R and block C is the minimum block of life frequency, and under the situation of block L for the highest block of life frequency, SP24 advances to step.

In step SP21, judge whether the counting of thermal source in two identical blocks of life frequency is identical, if the counting of thermal source is identical in two blocks, then advance, if the counting difference of thermal source in two blocks is then advanced to step SP23 to step SP22.

In step SP22, two blocks that life frequency is identical carry out ranking according to the rule of block C (first)＜block R (second)＜block L (the 3rd).For example, identical with the life frequency of block L at block R, and the counting of thermal source is identical, and under the minimum situation of the life frequency of block C, becoming block R and be first, block L and be second, block C is tertiary ranking.

In step SP23, in two identical blocks of life frequency, the side that the counting of thermal source is big is made as first, and a little side is made as second.And the minimum block of life frequency is made as the 3rd.

In step SP24, judge whether the counting of thermal source is identical in two identical and low blocks of life frequency, if the counting of thermal source is identical, then advances to step SP25, if the counting of thermal source is different, then advances to step SP26.

In step SP25; Because the highest block of life frequency has only one; So this block is made as first; Because the counting of thermal source is identical in two identical and low blocks of life frequency, so carry out ranking according to the rule of block C (first)＜block R (second)＜block L (the 3rd).For example, identical and counting thermal source is identical at the life frequency of block R and block L, and under the highest situation of the life frequency of block C, becoming block C and be first, block R and be second, block L is tertiary ranking.

In step SP26; Because the highest block of life frequency has only one; So this block is made as first; Because the counting of thermal source is different in two identical and low blocks of life frequency, so the side that the counting of thermal source is big is made as second, the side that the counting of thermal source is little is made as the 3rd.For example, at the life frequency of block R and block L identical and counting thermal source be block L greater than block R, and under the highest situation of the life frequency of block C, becoming block C and be first, block L and be second, block R is tertiary ranking.

In step SP27, because life frequency is all different, so carry out ranking from the high precedence of life frequency.For example, be time life frequency high, block L when minimum at the life frequency life frequency the highest, block C of block R, becoming block R and be first, block C and be second, block L is the 3rd.

In addition, when carrying out the ranking of each block, as stated, all will under scan pattern the pulse position of reality with confirmed that the deviation that produces on the position of thermal source revises, with the pulse value of location restore regulation.Consequently; At human body detection sensor 7 when end ZR drives to the right from left end ZL; Near the thermal source data the right-hand end ZR can not be obtained, at human body detection sensor 7 when end ZL drives to the left from right-hand end ZR, near the thermal source data the left end ZL can not be obtained.

So when left end ZL begins scan pattern, the counting that makes the thermal source of area I direction is zero, re-enters the counting of the thermal source of certain regulation.When right-hand end ZR begins scan pattern too, the counting that makes the thermal source of regional A direction is zero, re-enters the counting of the thermal source of certain regulation.Promptly; When end ZR drives to the right from left end ZL, the counting of the thermal source in I zone (I0, I1) (when end ZL drives to the left from right-hand end ZR, the counting of the thermal source of a-quadrant (A0, A1)) no matter the reaction of human body detection sensor 7 how; All be made as fixed value (for example, 3).

Through such mode, can eliminate the unfavorable condition of the thermal source of being not sure of a-quadrant and I zone, can positively carry out the whole thermal source in air conditioning zone and confirm.In addition, in this embodiment, the fixed value of the counting of thermal source is made as 3, but is not limited thereto.

More than the ranking of each block is illustrated.Then, the ranking to the zone in each block describes.

At first; Same with the ranking of each block; On 9 left and right directions (A～I direction), be divided into life region direction (region direction that the people is often arranged), moving area direction (region direction that the people moves), non-life zone (almost no one's region direction) three region directions.And; Zone in air conditioning zone shown in Figure 5; In the zone of 9 left and right directions and in the zone of depth direction (being respectively n, m, f zone), need only under the situation that has a life zone; The zone of this left and right directions is made as life region direction, and is made as the highest region direction of life frequency.

In addition; In the zone of 9 left and right directions and in life zone, the zone of depth direction (being respectively n, m, f zone), do not exist and exist under the situation of moving area; The zone of this left and right directions is made as the moving area direction, and is made as the high region direction of life frequency second.

In addition; In the zone of 9 left and right directions and under life zone, the zone of depth direction (being respectively n, m, f zone) and all non-existent situation of moving area; The zone of this left and right directions is made as non-life region direction, and is made as the minimum region direction of life frequency.

Figure 10 is the flow chart of the order decision in the zone in the expression block.In addition, in Figure 10, the trizonal ranking in some blocks is represented, in arbitrary block of block L, block C, block R, all used the identical way of thinking to carry out the ranking in zone.

In the step SP31 of Figure 10; In the zone of 9 left and right directions; Whether the counts of the thermal source during to the scan pattern of human body detection sensor 7 surpasses setting (for example 5 times) is detected; When counts does not surpass setting, be made as the on-fixed zone, from zone, get rid of by fixed mode fixing human detecting sensor 7.For example, as shown in Figure 7, B direction zone shown in Figure 5 is made up of the zonule of B0～B2; If the counts of the thermal source of B0～B2 does not reach setting; Then being judged as in B direction zone does not have thermal source, if the counts of thermal source more than setting, then is judged as in B direction zone thermal source is arranged.

In the step SP32 of Figure 10, judge trizonal in block life frequency difference whether in each.For example, if in the block L, then judge in regional each in a-quadrant, B zone, C whether difference of life frequency.And at trizonal life frequency all not simultaneously, SP48 advances to step.When in three zones, having identical regional of life frequency, SP33 advances to step.For example, in block L, be that life frequency second high zone, the area B is under the situation in the minimum zone of life frequency in the regional A zone the highest, zone C for life frequency, advance to SP33.

In step SP33; Trizonal life frequency in the block is compared, and when the life frequency in two zones was identical in three zones, SP41 advanced to step; When the life frequency of Zone Full was all identical in three zones, SP34 advanced to step.For example, when regional A was high regional of life frequency second for the highest zone of life frequency, zone C for the highest zone of life frequency, area B, SP41 advanced to step.

In step SP34; Judgement under scan pattern every drive stepping motor 8 one pulse detection to the counting of thermal source whether all different in three zones that are positioned at a same block; The counting of thermal source is not simultaneously in Zone Full; SP40 advances to step, if the counting of two thermals source is identical in three zones, then advances to step SP35.

In step SP35, if the counting of Zone Full thermal source is all identical in three zones, then advance to step SP36, as long as the counting of thermal source have one with other zones not simultaneously, SP37 advances to step.

In step SP36, because life frequency is identical in Zone Full, and the counting of thermal source is also identical, is that first, right zone are that second, left zone are the 3rd so the precedence between each zone during with fixed mode is made as middle section.For example, in block L,, then the B zone is made as first, the C zone is made as second, the a-quadrant is made as the 3rd if all identical at the counting of zone Zone Full life frequency and thermal source from the a-quadrant to C.

In step SP37, under the situation of the counting of the thermal source in the identical and zone of the counting of the thermal source in two zones less than the counting of the thermal source in other two zones, SP38 advances to step in the counting of each regional thermal source.In addition, under the situation of the counting of the thermal source in an and zone identical at the counting of the thermal source in two zones greater than the counting of the thermal source in other two zones, SP39 advances to step.

In step SP38; Because the counting in two zones is greater than another regional counting; So the ranking in two zones is carried out first and deputy ranking according to the rule in middle section (first)＜zone, the right side (second)＜zone, a left side (the 3rd), another zone is come the 3rd.For example, in block L, the counting of the thermal source of and zone C identical with area B at regional A at the counting of thermal source is during less than another zone, and becoming area B and be first, regional A and be second, zone C is tertiary ranking.

In step SP39; Because the counting in two zones is less than another regional counting; So the maximum zone of counting is first; The ranking in two zones of number is carried out second and tertiary ranking according to the rule in middle section (first)＜zone, the right side (second)＜zone, a left side (the 3rd) together.For example, in block L, at the counting of the counting of the thermal source thermal source of identical and zone C on regional A and area B during greater than another zone, becoming zone C and be first, area B and be second, regional A is tertiary ranking.

In step SP40, because all different, so, determine the precedence that each is regional according to the counting of thermal source at the counting of Zone Full endogenous pyrogen.For example, in block L, at the counting of the thermal source of the counting maximum of the thermal source of regional A and area B hour, becoming regional A and be first, zone C and be second, area B is tertiary ranking.

In step SP41, only have a different zone of life frequency but this when only different zone is lower than the life frequency in two zones in addition, SP42 advances to step, when being higher than the life frequency in other two zones, SP45 advances to step.For example; Regional A and area B are the highest zone of life frequency in block L; And under the situation of zone C for the minimum zone of life frequency, advancing to step SP42, is the minimum zone of life frequency at regional A and area B; And under the situation of zone C for the highest zone of life frequency, SP45 advances to step.

In step SP42, judge whether the counting of thermal source in two identical zones of life frequency is identical, if the counting of thermal source is identical in two zones, then advance, if the counting difference of thermal source in two zones is then advanced to step SP44 to step SP43.

In step SP43, ranking is carried out according to the rule in middle section (first)＜zone, the right side (second)＜zone, a left side (the 3rd) in two zones that life frequency is identical.For example, identical and counting thermal source is identical at the life frequency of regional A and area B, and the life frequency of zone C is when minimum, becoming area B and be first, regional A and be second, zone C is tertiary ranking.

In step SP44, in two identical zones of life frequency, the side that the counting of thermal source is more is made as first, and a less side is made as second.And the minimum zone of life frequency is made as the 3rd.

In step SP45, judge whether the counting of thermal source in two identical and low zones of life frequency is identical, if the counting of thermal source is identical, then advance to step SP46, if the counting of thermal source is different, then advance to step SP47.

In step SP46; Because the highest zone of life frequency has only one; So this zone is made as first; Because the counting of thermal source is identical in identical and low two zones of life frequency, so carry out ranking according to middle section (first)＜zone, right side (second)＜left regional (the 3rd 's) rule.For example, identical and counting thermal source is identical at the life frequency of regional A and area B, and under the highest situation of the life frequency of zone C, becoming zone C and be first, area B and be second, regional A is tertiary ranking.

In step SP47; Because the highest zone of life frequency has only one; So this zone is made as first; Because the counting of thermal source is different in two identical and low zones of life frequency, so the side that the counting of thermal source is more is made as second, the side that the counting of thermal source is less is made as the 3rd.For example, at the life frequency of regional A and area B identical and counting thermal source be area B greater than regional A, and under the highest situation of the life frequency of zone C, becoming zone C and be first, area B and be second, regional A is tertiary ranking.

In step SP48, because life frequency is all different, so carry out ranking according to the high order of life frequency.For example, under the minimum situation of life frequency time life frequency high, zone C the highest at the life frequency of regional A, area B, regional A is first, and area B is second, and zone C is the 3rd.

As stated, at first confirm the preferential precedence of each block, then determine the preferential precedence in each zone in the block.Then, with preferential precedence combination in the preferential precedence of each block and each zone in the block, the Zone Full of decision left and right directions (the preferential precedence of A～I).

Figure 11 is the figure of the order in the fixed mode zone of expression.On the basis of having carried out aforesaid each block, ranking that each is regional, shown in figure 11, carry out (the ranking of A～I) of 9 zones.At this, take concrete example and describe.

As shown in Figure 9, at first, carry out the ranking of each block.Consequently, carry out the ranking of block R, block C and block L.For example, being judged as block R is that first, block C are that second, block L are the 3rd.

Then, shown in figure 10, determine each the regional preferential precedence in each block.For example, in block R, regional G is first, and regional H is second, and area I is the 3rd; In block C, region D is first, and area E is second, and regional F is the 3rd; In block L, regional A is first, and area B is second, and zone C is the 3rd.

At first, in the step SP51 of Figure 11, in the contained zone of the highest block of fixed mode preferential precedence, the zone that fixed mode preferential precedence is the highest determines to be first in omnidirectional zone.For example, the situation of this embodiment, the highest regional G of preferential precedence among the block R that preferentially precedence is the highest is first in complete 9 directions.

Then, in step SP52, in the contained zone of the high block of fixed mode priority bit time second, the zone that fixed mode preferential precedence is the highest determines to be second in omnidirectional zone.For example, the situation of this embodiment, the highest region D of preferential precedence among the high block C of priority bit time second is second in complete 9 directions.

Then, in step SP53, in the contained zone of the high block of fixed mode priority bit order three, the zone that fixed mode preferential precedence is the highest determines to be the 3rd in omnidirectional zone.For example, the situation of this embodiment, the highest regional A of preferential precedence among the high block L of priority bit order three is the 3rd in complete 9 directions.

Then; In step SP54; Because the zone in the somewhere in all blocks temporarily has been assigned to first～the 3rd; So with the main points that step SP51～step SP53 is identical, in the contained zone of the highest block of fixed mode preferential precedence, the fixed mode priority bit time second high zone is confirmed as the 4th in omnidirectional zone.For example, the situation of this embodiment, the regional H that the priority bit among the highest block R of preferential precedence time second is high is the 4th in complete 9 directions.

Then, in step SP55, in the contained zone of the high block of fixed mode priority bit time second, the fixed mode priority bit time second high zone is determined to be the 5th in omnidirectional zone.For example, the situation of this embodiment, the area E that the priority bit among the high block C of priority bit time second time second is high is the 5th in complete 9 directions.

Then, in step SP56, in the contained zone of the high block of fixed mode priority bit order three, the fixed mode priority bit time second high zone is determined to be the 6th in omnidirectional zone.For example, the situation of this embodiment, the area B that the priority bit among the high block L of priority bit order three time second is high is the 6th in complete 9 directions.

Then, in step SP57, in the contained zone of the highest block of fixed mode preferential precedence, fixed mode priority bit order three high zones are determined to be the 7th in omnidirectional zone.For example, under the situation of this embodiment, the area I that priority bit order among the highest block R of preferential precedence three is high is the 7th in complete 9 directions.

Then, in step SP58, in the contained zone of the high block of fixed mode priority bit time second, fixed mode priority bit order three high zones are determined to be the 8th in omnidirectional zone.For example, the situation of this embodiment, the regional F that the priority bit order three among the high block C of priority bit time second is high is the 8th in complete 9 directions.

Then, in step SP59, in the contained zone of the high block of fixed mode priority bit order three, fixed mode priority bit order three high zones are determined to be the 9th in omnidirectional zone.For example, the situation of this embodiment, the zone C that the priority bit order three among the high block L of priority bit order three is high is the 9th in complete 9 directions.

As stated, to Zone Full decision permanent order.And, each order that under fixed mode, is determined, all in its zone towards the center of human body detection sensor 7, judge that detected thermal source is human body thermal source or human body thermal source in addition under scan pattern.But, though temporarily carry out all rankings of 9 directions, if thermal source does not exist, the zone that can not confirm that thermal source exists can take place also certainly then.In this case, when fixed mode precedence runs to thermal source non-existent when zone, do not exist and skip fixed mode precedence as thermal source, fixed mode precedence is shifted to next zone.

In addition; When fixed mode; In certain zone, begin thermal source when whether being the judgement of human body towards human body detection sensor 7, the influence of the waveform disorder when moving and avoid erroneous detection in order to get rid of human body detection sensor 7, the zone of under fixed mode, detecting is after the direction of human body detection sensor 7; Through beginning fixed test after the certain hour (for example, 5 seconds).Below; Will be when fixed mode judge that towards the direction of human body detection sensor 7 whether thermal source is that people's zone (9 directions of A～I) is called " FX "; The zone (9 directions of A～I) that will when scan pattern, not detect thermal source is called " on-fixed zone ", and describes.

In this embodiment, according to the set time of situation change to FX fixing human detecting sensor 7.Then, the decision to the set time describes.Figure 12 is the control flow chart of decision set time.

Shown in figure 12, at first in step SP61, judge whether FX is the life zone.Then, be that SP67 advances to step when living the zone being judged as FX, if not the life zone, then advance to step SP62.When getting into step SP67, with the situation in other zones (zones of 9 directions of A～I) irrespectively, will be made as T1 (for example, 120 seconds) set time.

Then, in step SP62, judge the zone that is judged as the on-fixed zone in the zone of 9 directions of A～I have what; If not enough certain the certain value M1 (for example, 3 zones) in on-fixed zone then advances to step SP66; If, then advance to step SP63 more than the certain value M1 at certain in the on-fixed zone.When getting into step SP66, be judged as and in other zones, also have many FX, be made as the set time T2 (for example, 60 second) shorter than set time T1.

Then, in step SP63, judge the zone that is judged as the on-fixed zone in the zone of 9 directions of A～I have what; If not enough certain the certain value M2 (for example, 7 zones) in on-fixed zone then advances to step SP65; If, then advance to step SP64 more than the certain value M2 at certain in the on-fixed zone.When getting into step SP65, be judged as the FX that in other zones, has to a certain degree.Be made as the set time T3 (for example, 90 second) shorter and longer than set time T2 than set time T1.

Then, in step SP64, will be in the zone of 9 directions of A～I as the fixed mode time lengthening in the zone that to have many on-fixed region decision be FX, be made as set time T4 (for example, 120 seconds).In addition, set time T4 is longer than set time T2 and T3.In addition, in this embodiment, set time T4 and set time T1 are made as identical, but are not limited thereto.

As stated; In the zone of 9 directions of A～I, to exist how many on-fixed zones to change the fixed mode set time; If FX is few in the zone of 9 directions, then with respect to the zone that is judged as FX, whether be the judgement precision of human body to fixing human detecting sensor 7 if improving for a long time; If the on-fixed zone is few; Then shorten the fixed mode set time, can improve indoor integral body is judged that whether thermal source is the speed of human body, can promptly realize comfortable air conditioning environment.

Then, to judging that whether the thermal source under scan pattern, confirmed is that the concrete control of human body describes.

At first, when permanent order was moved with above-mentioned precedence in the position that is judged as FX, human body detection sensor 7 drove to the direction of this FX.And, be that for fear of erroneous detection, whether through after the stipulated time, carrying out thermal source by human body detection sensor 7 is the judgement of human body after the FX of judgement of human body at human body detection sensor after this 7 towards whether.

Under fixed mode, in certain zone,, detect and under the state of having fixed the stipulated time, whether react towards human body detection sensor 7.At this moment, if human body, then movable possibility is big, so can detect temperature change with human body detection sensor 7, if can movable thermal source (for example, TV etc.), then can not detect temperature change with human body detection sensor 7.

Then, after the beginning fixed test, L1 (for example 3 seconds) at regular intervals judges the output of human body detection sensor 7 in FX, judges position of human body according to the combination of the reaction of human body detection sensor 7.At this moment, if inactive thermal source, then not reaction of human body detection sensor, for for thermal source movable the human body, human body detection sensor responds, so can carry out the judgement of the thermal source beyond human body and the human body.

In this embodiment; Human body detection sensor 7 by remote with human body detection sensor 7A with closely constitute with human body detection sensor 7B; Under the situation of only reacting with human body detection sensor 7A at a distance; Add setting (for example, 1) in remote f zone, zone in addition (m zone, n regional) is made as zero.For example, be under the situation of a-quadrant in FX, only add 1 at Af.

Only closely under the situation with human body detection sensor 7B reaction, add setting (for example, 1) in in-plant n zone, zone in addition (f zone, m regional) is made as zero.For example, be under the situation of a-quadrant in FX, only add 1 at An.

Add setting (for example, 1) remote in the m zone of middle distance with under human body detection sensor 7A and the situation about closely all responding with human body detection sensor 7B both sides, zone in addition (for example, f is regional, n regional) is made as zero.For example, be under the situation of a-quadrant in FX, only add 1 at Am.

And; Every separated stipulated time of the result of determination of position of human body (for example; Every at a distance from 30 seconds) all carry out accumulating operation, then will closely the accumulating operation number of times separately of (n zone), middle distance (m zone), remote (f is regional) as the detection resume preservation of position of human body.Then, be the basis with the detection resume of position of human body, judge people that each is regional, do not exist.In addition, even repeated detection is to the reaction of human body detection sensor 7 during (in this embodiment, being made as per 30 seconds) at the appointed time, as long as can detect once, the value that then adds at the detection resume just is " 1 ".

In addition, in this embodiment, life zone, moving area, non-life zone are judged based on these detection resume.That is, calculate the summation of region-wide detection resume, account for what of this region-wide detection resume summation, deciding life to distinguish by each regional detection resume.

At first, calculate the summation of the detection resume of region-wide (in this embodiment, about 9 directions, the degree of depth 3 zones amount to 27 zones), and calculate this zone and account for much ratios.Then, if the not enough regulation ratio of this ratio A (for example 3%) then is made as non-life zone, if more than regulation ratio A not enough regulation ratio B (for example 20%), then be made as moving area, if more than regulation ratio B, it is regional then to be made as life.In addition, regulation ratio A of this embodiment and regulation ratio B are not limited to the value of this embodiment record.

In addition, with " group (Set) " this expression way the stipulated time of carrying out accumulating operation is described in following, in this embodiment, be made as 30 seconds with one group, but be not limited thereto.

Figure 13 is the expression human body at, the control flow chart do not judged.Shown in figure 13, at first, in step SP71, judge whether current FX is the life zone.When being the life zone, SP79 advances to step, and when not being the life zone, SP72 advances to step.

In step SP79, during certain FX was fixed with human body detection sensor 7, each group was (in this embodiment; Per 30 seconds) all the detection resume to position of human body carry out accumulating operation, but during under fixed mode, fixing (for example, if set time T1; Then be 120 seconds) each group (in this embodiment; Per 30 seconds) the detection resume in all detect under the situation of reaction by human body detection sensor 7 at every turn, SP81 advances to step, confirms that human body exists.In addition, in step SP79, once also do not detect under the situation of reaction at human body detection sensor 7, SP80 advances to step, confirms that human body does not exist.

In step SP72, judge whether FX is moving area.Consequently, when being moving area, SP76 advances to step, and when being not moving area, SP73 advances to step.

In step SP63, during certain FX was fixed with human body detection sensor 7, each group was (in this embodiment; Per 30 seconds) all the detection resume to position of human body carry out accumulating operation, but during under fixed mode, fixing (for example, if set time T2; Then be 60 seconds) the detection resume of each group (in this embodiment, per 30 seconds) in human body detection sensor 7 number of times that detects reaction be that group more than 2 times exists under 2 groups of above situation, SP78 advances to step; Confirm that human body exists; Under situation about not existing more than 2 groups, SP77 advances to step, confirms that human body does not exist.

In step SP73, during certain FX was fixed with human body detection sensor 7, each group was (in this embodiment; Per 30 seconds) all the detection resume to position of human body carry out accumulating operation, but during under fixed mode, fixing (for example, if set time T3; Then be 90 seconds) the detection resume of each group (in this embodiment, per 30 seconds) in human body detection sensor 7 number of times that detects reaction be that group more than 3 times exists under 2 groups of above situation, SP75 advances to step; Confirm that human body exists; Under situation about not existing more than 2 groups, SP74 advances to step, confirms that human body does not exist.

As stated, to the thermal source of under scan pattern, confirming, whether be human body at the fixed mode thermal source that judges.In addition, in step SP73, step SP76, step SP79, the reaction times of the human body detection sensor 7 that uses in order to be judged as human body and group number etc. is not limited to above-mentioned numerical value, can suitably change.

In addition, 9 directions in the scan pattern stage to A～I direction are judged as under the situation in on-fixed zone, and the Zone Full to contained remote zone, this direction zone, middle distance zone, nearby region is judged to be human body and does not exist.

Based on the human body of judging as stated, not judgement, decision air conditioning zone.In addition, as shown in Figure 5, in the air conditioning zone that is subdivided into 27 zones, imagine the situation that human body is crossed over a plurality of zones, adopt the way of thinking for big zone is gathered in a plurality of zones.In this embodiment, shown in figure 14, gathering is 9 big zones.

That is, in this embodiment, regional An, Bn, Cn are made as big area L n; Region D n, En, Fn are made as big zone C n, regional Gn, Hn, In are made as big region R n, regional Am, Bm, Cm are made as big area L m; Region D m, Em, Fm are made as big zone C m, regional Gm, Hm, Im are made as big region R m, regional Af, Bf, Cf are made as big area L f; Region D f, Ef, Ff are made as big zone C f, regional Gf, Hf, If are made as big region R f.

Then, the definite method to the air conditioning zone describes.Figure 15 is the decision flow chart in air conditioning zone.Shown in figure 15; In step SP91, judge that in arbitrary zone in 27 zones, whether having one is judged to be the zone that human body exists, when having the people zone; SP95 advances to step; The big zone decision that will comprise the zone that human body exists is the air conditioning zone, and when not having regional that human body exists, SP92 advances to step.

In step SP92,, judge whether to exist the life zone owing to there is not the zone of having confirmed that human body exists.Consequently, when having the life zone, SP94 advances to step, and the big zone decision that will comprise the life zone is the air conditioning zone, and when not having the life zone, SP93 advances to step.

In step SP93, do not exist owing to confirmed zone, life zone that human body exists, so, be big zone C m is made as the air conditioning zone with the big zone of central authorities from the viewpoint of air conditioning optimization.

Below, air conditioning control is carried out in the air conditioning zone of decision as stated, and this air conditioning control is described.

At first; Wind direction control is by big regional (in this embodiment at one; With big area L f is that example describes) in three zones (in this embodiment, being that example describes) with regional Af, Bf, the Cf that constitutes big area L f where detect human body and difference.

Figure 16 is the flow chart of the wind direction control when determining only to have an air conditioning zone.At first, according to the flow chart of Figure 15, the only selected Lf in the air conditioning zone.In this case, in step SP101, when having only one, SP107 advances to step in three zones, to have the people to judge (human body is being judged, is judged to be human body and exists), is having the people to be judged to be two when above, and SP102 advances to step.

At first, with Figure 17 the situation of step SP107 is described.Shown in figure 17, the situation of step SP107 is that the someone judges and have only one (among Figure 17, be located at made the people among the regional Af judge).In this case, drive left and right sides wind direction blade, blade (below be called the control of first wind direction) up and down with wind direction towards being made as the mode of having made the central authorities that the regional Af that the people judges is arranged.Thus, since wind direction directly towards detected human body, so can realize comfortable air conditioning.

Then, in step SP102, judge whether that all having made the people in three zones judges.Then, all be someone when judging at Zone Full (regional Af, Bf, Cf), SP106 advances to step, all is not someone when judging at Zone Full, and SP103 advances to step.

With Figure 18 the situation of step SP106 is described.Shown in figure 18, the situation of step SP106 is for having the people to judge to have three (among Figure 18, are located at regional Af, Bf, Cf Zone Full and all made the people and judged).In this case, the mode of having made the central authorities that the area B f that the people judges is arranged drives left and right sides wind direction blade, wind direction blade carries out air conditioning (below be called the control of second wind direction) up and down towards being made as with wind direction.Thus, can be to the comfortable air conditioning of the whole realization of big area L f.

Then, in step SP103, judging has the people whether to judge adjacency.Then, be judged as in abutting connection with the time, SP105 advances to step, be judged as not in abutting connection with the time, SP104 advances to step.

With Figure 19 the situation of step SP104 is described.In step SP104, made the zone that has the people to judge and had (in this embodiment, establish regional Af and zone C f and made the people and judge) away from each other.In this case, do not drive left and right sides wind direction blade, wind direction blade (below be called the control of the 3rd wind direction) up and down with wind direction towards being made as the mode of having made the central authorities that the area B f that the people judges is arranged.Thus, wind direction can be partial to any among regional Af and the zone C f, can realize comfortable air conditioning equably.

With Figure 20 the situation of step SP105 is described.In step SP105, made the zone that has the people to judge be adjacent to each other and exist (in this embodiment, establish regional Af and area B f and made the people and judge).In this case, made the mode that the zone central authorities each other that the people judges are arranged and driven left and right sides wind direction blade, wind direction blade up and down towards being made as, carried out air conditioning (below be called the control of the 4th wind direction) with wind direction.Thus, wind direction can be partial to any among regional Af and the area B f, can realize comfortable air conditioning equably.

More than wind direction control when only big zone becomes the air conditioning zone be illustrated.But, shown in figure 21, in a block areas (in this embodiment, block L), exist a plurality of big zones to be decided to be the situation in air conditioning zone.Example shown in Figure 21 is the situation that the big area L f of leap and big two big zones of area L m detect human body.In addition, this is an embodiment, is not limited thereto.

Shown in figure 21, when a plurality of big zones in a block areas are confirmed as the air conditioning zone, make left and right sides wind direction blade swing, carry out air conditioning whole in the block areas.At this moment, of this embodiment, need to cross over big area L f and carry out air conditioning with big two big zones of area L m.So; In this case; Left and right sides wind direction blade is swung in block areas and is carried out air conditioning, and per stipulated time drives wind direction blade up and down, alternately makes wind direction carry out air conditioning (in this embodiment towards big zone; Per stipulated time drives wind direction blade up and down, alternately makes wind direction towards big area L f and big area L m.Below be called tendencies to control).Consequently, can carry out the interior air conditioning of comfortable block areas.

In addition, shown in figure 22, exist in the situation that a plurality of block areas detect human body.Example shown in Figure 22 is the situation that detects human body at block L (big area L f with big area L m) and block R (region R f greatly).In addition, this is an embodiment, is not limited thereto.

Wind direction control is that first wind direction control～the tendencies is carried out to control combination together basically.For example, shown in figure 22, when different block areas detects human body, in block L, carry out tendencies to control, in block R, carry out the control of first wind direction.Then, per stipulated time drives left and right sides wind direction blade, makes wind direction towards corresponding block areas direction, through alternately carrying out control of first wind direction and tendencies to control, realizes comfortable room air adjusting.

But; A plurality of big zones are judged as under the situation in air conditioning zone in same block areas; Tendencies to control in; Alternately drive wind direction blade up and down, but be detected under a plurality of situation as the air conditioning zone, alternately do not drive wind direction blade up and down in different block areas shown in figure 22.

In this embodiment; Be detected a plurality of situation in different block areas as the air conditioning zone; And under the situation of swinging control in the block areas, when cooling turned round, the wind direction that makes wind direction blade up and down from indoor unit 1 was towards the big zone that is judged as air conditioning zone farthest (Figure 22 with left and right sides wind direction blade; Big area L f); When heat supply was turned round, the wind direction of wind direction blade was towards the big zone that is judged as nearest air conditioning zone (Figure 22, big area L m) about indoor unit 1 makes.This is through because of the heavy character that descends, gently rises because of warm air of cold air realizes, can carry out comfortable air conditioning to integral body in the block areas.

In addition, shown in figure 23, exist in the situation that whole block areas detect human body.Example shown in Figure 23 is the situation that detects human body at block L (big area L f and big area L m), block C (big zone C f) and block R (big region R f).In addition, this is an embodiment, is not limited thereto.

When in whole block areas, detecting human body,, might in arbitrary block areas, all can not realize comfortable air conditioning if be fixed in that all blocks carry out air conditioning then the time is elongated.

Thereby, when when three block areas detect human body, alternately make block areas (block R and the block L) direction of wind direction towards right ends, and, in block areas, make left and right sides wind direction blade swing carrying out air conditioning.In addition; When cooling turns round; The wind direction of wind direction blade is towards the big zone that is judged as air conditioning zone farthest (Figure 23, big area L f or big region R f), when heat supply is turned round about indoor unit 1 makes; The wind direction of wind direction blade is towards the big zone that is judged as nearest air conditioning zone (Figure 23, big area L m or big region R f) about indoor unit 1 makes.

In addition, the block areas (block C) in the middle does not make wind direction fixedly carry out air conditioning, but only change when block R (or from block R to block L) moves from block L wind direction towards.But,,, can realize comfortable and energy-conservation air conditioning so can not damage comfortableness owing to make left and right sides wind direction blade swing carry out air conditioning at both ends.

In addition, owing to confirm thermal source in the scan pattern, so during the running of air conditioning during this time, make to blow out wind and carry out air conditioning towards the direction of regulation.Up to definite thermal source, drive left and right sides wind direction blade and wind direction blade up and down, both can blow out to center direction, also can swing.In this embodiment, consider the comfortableness that the room is whole, make wind direction carry out the air conditioning running so that can carry out air conditioning equably towards center direction.

And, under scan pattern,, left and right directions confirmed under the situation of thermal source whether under scan pattern, do not judge as yet is human body during driving at human body detection sensor 7.But, in order to implement high efficiency air conditioning running as soon as possible, judge before whether thermal source be human body in fixed mode, carry out the air conditioning running towards the thermal source direction that scan pattern is confirmed.

Particularly, by whether existing thermal source to change wind direction at block L shown in Figure 8, block C, block R under the scan pattern.

At first, only under the situation of single block, the control wind direction carries out the air conditioning running to the center direction of the block of having confirmed thermal source.That is, only exist under the situation of thermal source in the scope of block L, make wind direction carry out the air conditioning running towards the center direction of block L; Only exist under the situation of thermal source in the scope of block C, make wind direction carry out the air conditioning running towards the center direction of block C; Only exist under the situation of thermal source in the scope of block R, make wind direction carry out the air conditioning running towards the center direction of block R.

Then, confirmed at a plurality of blocks under the situation of thermal source that by the difference of the block of confirming, wind direction is different.That is, all exist under the situation of thermal source, between the center direction of the center direction of block L and block C, swingingly carry out the air conditioning running at block L and block C.All exist under the situation of thermal source at block R and block C, between the center direction of the center direction of block R and block C, swingingly carry out the air conditioning running.

In addition; All exist under the situation of thermal source at block L and block R; The control wind direction carries out the air conditioning running to the center direction of block C, all exists under the situation of thermal source at block L, block C and block R, and the control wind direction carries out the air conditioning running to the center direction of block C.Why under block L and block R have confirmed the situation of thermal source, do not swing and control wind direction and carry out the air conditioning running to the center direction of block C; Be because just in case the thermal source of confirming is not under the situation of people but thermals source such as TV; If swingingly carry out the air conditioning running; Wind direction towards with the human body rightabout during, may give and brought unplessantness displeasure indoor people.Therefore, confirmed under the situation of thermal source, do not carried out the air conditioning running, but the control wind direction carries out the air conditioning running to the center direction of the block C of middle, keeps comfort thus through swing at the block that as block R and block L, leaves.

In addition, even the wind direction can not confirm human body under the arbitrary situation in scan pattern, fixed mode the time also can carry out air conditioning based on Learning Control so far.

In addition, in this embodiment, be not sure of in scan pattern under the situation of thermal source, under fixed mode, human body detection sensor 7 stopped the whole fixed-direction of 9 region directions.Through such mode, even when scan pattern, be not sure of under the situation of thermal source, also can under fixed mode, reaffirm thermal source, can carry out and the corresponding air conditioning control of the situation of thermal source, can not damage comfortableness.

In addition, when when different blocks detects human body, in order promptly to carry out comfortable air conditioning running, the block that exists from previous detected human body begins the air conditioning running.That is, though be judged as situation shown in figure 21 at first, the flow process progress along with human detection perhaps can become situation shown in figure 22.In this case; The flow process of wait human detection to the end; Do not carry out and the corresponding air conditioning running of human body, but carry out immediately and the corresponding air conditioning running in the position of human body, can promptly realize comfortable air conditioning running thus once detecting human body.

As stated, in this embodiment,, can distinguish human body and thermal source, carry out comfortable air conditioning control through using driving human body detection sensor.
