People's location estimating > that < utilizes human body detection device to carry out

Fig. 5 represents the people position critical region being detected by sensor unit 24,26,28, and whether the region that sensor unit 24,26,28 can detect respectively below has people.

Sensor unit 24: region A+B+C+D

Sensor unit 26: region B+C+E+F

Sensor unit 28: region C+D+F+G

, in the indoor set of air conditioner of the present invention, the region part that can be detected by each sensor unit 24,26,28 overlaps, the sensor unit that usage quantity is less than the quantity of region A～G detects in each region A～G, whether someone exists.Table 1 represents the output of each sensor unit 24,26,28 and the relation determinating area (being judged to be people's region).In addition, in table 1 and the following description, sensor unit 24,26,28 is called first sensor 24, the second sensor 26, the 3rd sensor 28.

[table 1]

Fig. 6 is used the first to the 3rd sensor 24,26,28 for A～G each region in region being set to the flow chart of region characteristic described later, Fig. 7 is used the first to the 3rd sensor 24,26,28 to judge the flow chart that whether has people in which region of region A～G, with reference to these flow charts, below people's position decision method is described.

In step S1, first for example, with the period T 1 (5 seconds) of regulation, judge in each region, whether someone exists, but about this decision method, take situation that in determinating area A, B, C, whether someone exists as example, with reference to Fig. 8, describe.

As shown in Figure 8, in the period T 1 before time t1, the first to the 3rd sensor 24,26,28 is in the situation of OFF (no pulse), is judged to be nobody in time t1, region A, B, C (A=0, B=0, C=0).Then, time t2 from time t1 to period T 1, only first sensor 24 is exported ON signal (having pulse), second and the 3rd in sensor 26,28 situation that is OFF, be judged to be has people in t2, region A, nobody in region B, C (A=1, B=0, C=0).In addition, the first and second sensor 24,26 output ON signals time t3 from time t2 to period T 1, in the situation that the 3rd sensor 28 is OFF, be judged to be has people in time t3, region B, nobody in region A, C (A=0, B=1, C=0).Below, similarly each cycle T1 is judged in each region A, B, C, whether someone exists.

According to this result of determination by each region A～G differentiate the first area (region of being everlasting) of being everlasting of behaving, people short second area of time (region is passed through in the region that region, dead time that people only passes through are short etc.), people very short the 3rd region of time (the non-life region that the people such as wall, window goes hardly).Below, first area, second area, the 3rd region are called respectively to life subregion I, life subregion II, life subregion III, and life subregion I, life subregion II, life subregion III also can be called respectively the region of region characteristic I, the region of region characteristic II, the region of region characteristic III.In addition, life subregion I (region characteristic I), life subregion II (region characteristic II) are collectively referred to as life region (region of people's life), with respect to this, life subregion III (region characteristic III) is as non-life region (region that people does not live), also can more classification be carried out in the region of life according to the frequency whether someone exists.

The step S3 of this differentiation in the flow chart of Fig. 6 carries out later, about this method of discrimination, with reference to Fig. 9 and Figure 10, describes.

Fig. 9 is illustrated in the situation that the indoor set of air conditioner of the present invention is set in the LD of the 1LDK (dining room+kitchen, 1 bedroom+living room) consisting of a Japanese room, LD (living room hold concurrently dining room) and kitchen, the place of being everlasting that the region representation experimental subjects in Fig. 9 shown in ellipse is declared.

As mentioned above, each period T 1 is judged in each region A～G, whether someone exists, as reaction result (judgement) output 1 (responding) or 0 (reactionless) of period T 1, after multi-pass operation, the sensor output clearing all in step S2.

In step S3, determine whether the accumulation duration of runs through the air conditioner of regulation.When being judged to be not pass through the stipulated time in step S3, return to step S1, when being judged to be through the stipulated time, by the reaction result of accumulating in each region A～G and two threshold value comparisons, thereby each region A～G is differentiated respectively to any for life subregion I～III in this stipulated time.

With reference to the Figure 10 that represents long-term accumulated result, be described in further detail, set first threshold and the Second Threshold less than first threshold, in step S4, judge that whether the long-term accumulated result of each region A～G is more than first threshold, be judged to be many regions and in step S5, differentiate for life subregion I.In addition, in step S4, when being judged to be the long-term accumulated result of each region A～G when fewer than first threshold, in step S6, whether the long-term accumulated result of judging each region A～G is more than Second Threshold, is judged to be many regions, differentiates for life subregion II in step S7, and be judged to be few region, in step S8, differentiate for life subregion III.

In the example of Figure 10, region C, D, G differentiate as life subregion I, and region B, F differentiate as life subregion II, and region A, E differentiate as life subregion III.

In addition, Figure 11 is illustrated in the situation that the indoor set of air conditioner of the present invention is set in the LD of another 1LDK, and the long-term accumulated result of Figure 12 under representing in view of the situation differentiated the result of the A～G in each region.In the example of Figure 11, region B, C, E differentiate as life subregion I, and region A, F differentiate as life subregion II, and region D, G differentiate as life subregion III.

In addition, the differentiation of above-mentioned region characteristic (life subregion) was carried out repeatedly in each stipulated time, but only otherwise the mobile indoor sofa that needs to differentiate, the dining table etc. of being configured in are differentiated result almost constant.

Then,, with reference to the flow chart of Fig. 7, about the final decision that in each region A～G, whether someone exists, describe.

Step S21～S22, due to identical with the step S1～S2 in the flow chart of above-mentioned Fig. 6, so its explanation is omitted.In step S23, determine whether the reaction result of the period T 1 that obtains stated number M (for example 15 times), when being judged to be period T 1, do not reach stated number M, return to step S21, and reach stated number M when being judged to be period T 1, in step S24, using the total of the reaction result of period T 1 × M as number of times between the accumulation stage of reaction, calculate number of times between the accumulation stage of reaction of once dividing.Repeatedly carry out repeatedly the calculating of number of times between this accumulation stage of reaction, in step S25, determine whether the result that calculates that reaches for example, between the accumulation stage of reaction that stipulated number divides (N=4) number of times, when being judged to be not reach stipulated number, return to step S21, and when being judged to be to reach stipulated number,, in step S26, between the accumulation stage of reaction that the region characteristic based on already differentiating and stipulated number divide, number of times infers in each region A～G, whether someone exists.

In addition, in step S27, from the number of times (N) that calculates of number of times between the accumulation stage of reaction, deduct 1, return to step S21, thereby repeatedly carry out the calculating of number of times between accumulation stage of reaction that stipulated number divides.

Table 2 represents the resume of the reaction result of up-to-date once dividing (time T 1 × M), in table 2, and for example number of times between the accumulation stage of reaction of once dividing in ∑ A0 meaning region A.

[table 2]

At this, between the accumulation stage of reaction of once dividing before ∑ A0, number of times is ∑ A1, between its accumulation stage of reaction of once dividing before, number of times is ∑ A2 in addition ... the in the situation that of N=4, in the past resume of four times points (∑ A4, ∑ A3, ∑ A2, ∑ A1), about life subregion 1, even if once between the above accumulation stage of reaction, number of times, for once, has also been judged to be people.In addition, about life subregion II, in the past in the resume of four times, if once between the above accumulation stage of reaction, number of times has more than twice, be judged to be people, and about life subregion III, in the past in the resume of four times, if between the more than twice accumulation stage of reaction there be more than three times number of times, be judged to be people.

Then, from the above-mentioned judgement elapsed time T1 × M whether someone exists, equally according to resume, the life subregion of four times point of the past with accumulate the number of times deduction whether someone exists between the stage of reaction.

, in the indoor set of air conditioner of the present invention, the sensor that usage quantity is fewer than the quantity of critical region A～G infers whether someone exists, so there is the possibility of the position of mistaking people in the deduction of every specified period, so with whether be the location estimating that repeat region independently avoids carrying out people in independent specified period, between the accumulation stage of reaction in each region of trying to achieve according to the regional determination result of the region characteristic of the regional determination result of the every specified period of long-term accumulation and the N time point of every specified period of accumulation, the resume in the past of number of times are inferred people's location, thereby obtain the people's that probability is high location estimating result.

Table 3 represents so to determine whether that someone exists, and is set as T1=5 second, inferring the required time, not inferring the required time in the situation of M=12 time.

[table 3]

Life subregion	Inferring	Do not inferring
			Ⅰ	60 seconds (soon)	240 seconds (slowly)
Ⅱ	120 seconds (standard)	180 seconds (standard)
			Ⅲ	180 seconds (slowly)	120 seconds (soon)

So, the region that will carry out air conditioning by the indoor set of air conditioner of the present invention is divided into after multiple region A～G by the first to the 3rd sensor 24,26,28, determine the region characteristic (life subregion I～III) of each region A～G, according to the region characteristic of each region A～G, change and inferring the required time and do not inferring the required time in addition.

; change after air conditioning setting; wind to before need about one minute; even for example, set so the short time (several seconds) is changed air conditioning; can not damage comfortableness yet; moreover, and, for people, occupy soon (Testis ぐ い な い) place from energy-conservation viewpoint, preferably not too carry out air conditioning.Therefore, first detect in each region A～G, whether someone exists, especially the air conditioning in the region that has people is set to optimization.

In detail, using differentiate as the region of life subregion II in required time of no deduction as standard, in the region of differentiating for life subregion I, take the existing as the short time interval deduction people in the region of life subregion II than differentiation, and in the situation that people leaves from this region, infer existing of people take the time interval longer as the region of life subregion II than differentiation, thereby inferring that the required time is set shortlyer, do not inferring that the required time is set longlyer.On the contrary, in the region of differentiating for life subregion III, take the existing as the long time interval deduction people in the region of life subregion II than differentiation, and in the situation that people leaves from this region, take not the existing as the short time interval deduction people in the region of life subregion II than differentiation, thereby in the required time of deduction, set longlyer, in the required time of deduction, do not set shortlyer.In addition, as mentioned above, the life subregion in each region changes because of long-term accumulated result, correspondingly, is inferring the required time and in the required time of deduction, be not also set to variable.

In addition, the Region Segmentation of Figure 14, the region quantity in its orientation is set manyly than the region quantity of people position critical region, at least two orientation belong to each region of people position critical region, these at least two Obstacle Position critical regions are observed and are configured in left and right from indoor set, but the mode that also can belong to each one position critical region with at least one orientation is carried out Region Segmentation, carries out air conditioning control.

In addition, in the cutting apart of the region of Figure 14, each region of many individual positions critical region is divided according to the distance apart from indoor set, belong to the people position critical region in the region that approaches indoor set orientation region quantity than belong to away from the region quantity in orientation of people position critical region in region set manyly, but also can, regardless of the distance apart from indoor set, the orientation quantity that belongs to each one position critical region be set as with number.

The detection action of < obstacle detector and data processing >

As mentioned above, air conditioner of the present invention, by in human body detection device surveyed area A～G, whether someone exists, and there is clear in the checkout gear detection orientation A1～G2 that breaks the barriers, according to the detection signal (testing result) of the detection signal of human body detection device (testing result) and obstacle detector, drive and control the upper lower panel 12 and the left and right fin 14 that as wind direction, change parts, thereby comfortable space is provided.

Human body detection sensor for example can detect whether someone exists by detecting the infrared ray radiating from human body, and hyperacoustic back wave that obstacle detector sends by reception detects the distance of barrier, so can not differentiate people and barrier.

When people being thought by mistake while being barrier, can not carry out air conditioning to the region that has people, or likely directly people's blow air is regulated to wind (air-flow), result can cause the air conditioning control of non-efficiency or give the air conditioning control of discomfort.

Therefore, about obstacle detector, carry out the data processing of following explanation, only detect barrier.

First, the driving method of ultrasonic sensor 32 is described with reference to Figure 15.

As shown in figure 15, in in main body 2, be provided with three substrates 48,50,52 of mutual electrical connection, be arranged on the movable parts such as front panel 4 in main body 2, upper lower panel 12, left and right fin 14 and controlled by first substrate 48, the 3rd substrate 52 is installed with ultrasonic sensor 32 one.

In addition, on second substrate 50, be provided with sensor input enlarging section 54, frequency band enlarging section 56, comparing section 58 and latch circuit portion 60, the ultrasonic wave transmitted signal of exporting from first substrate 48 inputs to sensor input enlarging section 54, after sensor input enlarging section 54 voltage amplifications, input to the 3rd substrate 52.Ultrasonic sensor 32 sends ultrasonic wave according to the signal being transfused to towards each address described later, receives its back wave, to frequency band enlarging section 56, exports.As ultrasonic wave transmitted signal, for example use the signal that repeatedly carries out the 50kHz of 50% dutycycle (duty) of ON/OFF with 10 μ s, in frequency band enlarging section 56, amplify near signal 50kHz.

The output signal of frequency band enlarging section 56 is transfused to comparing section 58, compares with the threshold value that is set in the regulation in comparing section 58.Comparing section 58 is exported the signal of L rank (low level) in the case of the output signal ratio threshold value of frequency band enlarging section 56 is large to latch circuit portion 60, and in the case of the output signal ratio threshold value of frequency band enlarging section 56 is little, the little latch circuit of the signal portion 60 of H rank (high-level) is exported.In addition, first substrate 48 is exported for separating of the reception marking signal that disturbs (noise) to latch circuit portion 60.

In addition, Figure 15 represents the structure that ultrasonic sensor 32 is transceiver type, but naturally also can use the structure of sender and receiver split.

Figure 16 represents the latch circuit portion 60 consisting of RS (putting 1, set to 0 (reset, arrange)) trigger (reset set flipflop), and table 4 represents according to the output from latch circuit portion 60 (Q) of two inputs (from the input (RESET input) of comparing section 58 with from the input (SET input) of first substrate 48) decision.In table 4, H* represents, under RESET input and SET input be all the situation of L rank, is output as H rank, and RESET inputs and inputs with SET that to export rank different in order which first to arrive H rank by the situation of H rank.

[table 4]

Marking signal	Comparator output	Latch circuit output
			SET	RESET	Q
L	L	H *
			L	H	H
H	L	L
			H	H	Keep intact

In addition, Figure 17 is the summary sequential chart that represents the state of each signal, as shown in figure 17, when the running of air conditioner starts, inputs the signal of H rank from comparing section 58 to latch circuit 60.In addition, the sensor input enlarging section 54 output ultrasonic wave transmitted signals from first substrate 48 to second substrate 50, while being transfused to the 3rd substrate 52 from the signal of sensor input enlarging section 54, ultrasonic sensor 32 sends ultrasonic wave towards the address setting.

In addition, after the transmission of ultrasonic wave transmitted signal, be likely subject to the interference effect from surrounding environment, in the situation that having interference effect, via frequency band enlarging section 56, input comparing section 58.In comparing section 58, by inputted signal and predefined threshold value comparison, in the large situation of threshold value, the signal of L rank is exported to latch circuit 60.But, at this moment the signal of inputting comparing section 58 is not owing to being that back wave from living space is received the signal generating by ultrasonic sensor 32, so according to sending the sensor output token time of setting regulation of ultrasonic wave transmitted signal, in the sensor output token time, the latch circuit 60 by the reception marking signal of L rank from first substrate 48 to second substrate 50 is exported.

Therefore the ultrasonic wave of, exporting to first substrate 48 from latch circuit 60 receives signal and maintains H rank.

On the other hand, the ultrasonic wave sending from ultrasonic sensor 32 is radiated living space, this back wave (first wave) is received by ultrasonic sensor 32, via frequency band enlarging section 56, input the signal of comparing section 58 than in the large situation of threshold value, similarly the signal of L rank is exported to latch circuit 60.But, the sensor output token time is owing to setting shortly than the time interval that transmits a signal to back wave reception signal from ultrasonic wave, so reception marking signal is at this moment H rank, so the ultrasonic wave of exporting to first substrate 48 from latch circuit 60 receives signal, be L rank.

The time that ultrasonic wave reception signal maintains H rank means that ultrasonic sensor 32 sends ultrasonic wave, to the time t that receives its back wave (first wave), so as mentioned above,, the distance B from ultrasonic sensor 32 to barrier is by trying to achieve time t and velocity of sound C substitution D=Ct/2.

In addition, on a certain address, complete regulation measurement, calculate time, first substrate 48 sends ultrasonic sensor horizontal drive with motor driver 62 to horizontally rotating with signal, driving horizontally rotates with motor 44, and ultrasonic sensor vertical drive is sent to vertical rotary motor driver 64 with signal, drive motor 46 for vertical rotary, thereby change the address that will measure.

I shown in table 5 and the j address of measuring of indicating, the angle of vertical direction and the angle of horizontal direction represent respectively above-mentioned angle of depression α and observe the angle beta from the datum line in left side towards right measurement from indoor set.That is, from indoor set, observe, in the scopes that 5 degree～80 are spent in vertical direction, 10 degree～170 are spent in the horizontal direction, set each address, ultrasonic sensor 32 is measured each address, scans living space.

[table 5]

In addition, utilize the full scan of the living space that ultrasonic sensor 32 carries out, when the running that is divided into air conditioner starts and when running stops, carrying out, table 6 represents the scanning sequency of ultrasonic sensor 32.

[table 6]

; when the running of air conditioner starts; from address (0; 0) in each address of address (32,0), carry out in turn range measurement (position probing of barrier), then; from address (32; 1) to each address of address (0,1), carry out in turn range measurement, the scanning when running that completes air conditioner starts.

On the other hand, when the running of air conditioner stops, from address (0,2) to address (32,2) in each address, carry out in turn range measurement, then in from address (32,3) to each address of address (0,3), carry out in turn range measurement, this is operated repeatedly, when the range measurement of address (0,15) completes, the scanning when running that completes air conditioner stops.

So, when the running that utilizes ultrasonic sensor 32 to be divided into air conditioner to the full scan of living space is started and when running stops, carrying out, is the judgement that has or not in order to carry out efficiently barrier.; when running stops; the movable key element of compressor etc. all stops; compared with while starting with the running of air conditioner, be difficult to be interfered, so be more satisfactory environment for the range measurement that utilizes ultrasonic sensor 32 to carry out; but only when stopping, the running of air conditioner carries out the full scan of living space; when running starts, ultrasonic sensor 32 does not react completely, not only can give the insincere sense of occupant, also can make increase the sweep time after running stops.

In addition, the scanning when running of air conditioner starts be limited to the angle of depression 10 spend with interior be because, the running of air conditioner has people's possibility higher while starting, only to region that people's possibility is higher not detected, having the region of wall to scan, can effectively utilize measurement data (because people is not barrier, so as described later, have the data in people's region not use).

Then, the range measurement apart from barrier while starting about the running of air conditioner, describes with reference to the flow chart of Figure 18.

First, in step S31, drive the preset processing with motor 44 and vertical rotary motor 46 that horizontally rotates of ultrasonic sensor 32.Preset processing refers to address (0,0) is set as to origin position, and address (16,0) are set as to center, will horizontally rotate with motor 44 and vertical rotary motor 46 after origin position is reset the control stopping in center.

In addition, three substrates 48,50,52 are connected by lead-in wire respectively, so in following step S32, carry out the OBD processing for being determined with the ultrasonic sensor 32 abnormal without the broken string going between, mistake connection etc., when being judged to be not have when abnormal in step S33, shift to step S34, and be judged to be when abnormal, to complete range measurement flow process.

In step S34, will horizontally rotate and be set as target primary position ((i, j)=(0,0)) with motor 44 and vertical rotary motor 46, in following step S35, determine whether these motors 44,46 are set in to target location.In step S35, when being judged to be to be set in target location, shift to step S36, and when being judged to be not to be set in target location,, in step S37, horizontally rotate the driving processing with motor 44 and disposal rotating motor 46, return to step S35.

In step S36, the standby stipulated time (for example 1 second), so that ultrasonic sensor 32 can maintain normal condition, is carried out Interference Detection processing in step S38.That is, ultrasonic sensor 32, owing to being easily subject to the impact of sound equipment interference or vibration or electromagnetic interference, is determined with without the interference effect from surrounding environment, shifts to range measurement action.

About this Interference Detection processing, with reference to the sequential chart of Figure 19, describe.

(therefore Interference Detection carries out when ultrasonic wave transmitted signal is L rank, comparing section 58 is output as H rank), before sending ultrasonic wave transmitted signal, the sound wave reception period (for example 100ms) of detection from the regulation of the interference of surrounding environment is set.

In addition, the mark time (for example 12ms) of regulation was set before Interference Detection, thereby guarantee that ultrasonic wave when Interference Detection starts receives the H rank of signal, after the mark time, start Interference Detection, for example, in per stipulated time (4ms), detect and disturb, in comparing section 58, the threshold value setting and detected interference are compared.In addition, in order to prevent misinterpretation, read in for twice from Interference Detection and start for example, through out-of-date ultrasonic wave, to receive signal to the stipulated time (100ms), read in for twice in the consistent situation for H rank (not disturbing threshold value) and be judged to be " noiseless ", even and a side is in the situation of L rank (disturbing as more than threshold value), be also judged to be " having interference ".

Return to the flow process of Figure 18, in following step S39, determined whether interference, be judged to be when noiseless, to shift to step S40, and while being judged to be interference, shift to step S41.

In step S40, in identical address, obtain 8 secondary data, judge whether the range measurement of the data based on obtaining completes, when being judged to be range measurement and not completing, in step S42, carry out, after transmission processing, in step S43, carrying out reception & disposal, return to step S40.On the contrary, in step S40, when being judged to be range measurement and completing, in step S44, carry out determining and processing apart from sequence number.

In addition, because these processing are carried out in first substrate 48 and second substrate 50, so first substrate 48 and second substrate 50 play the effect as Obstacle Position detection part.

In addition, when the distance sequence number in step S44, determine and finish dealing with, in step S45, judge and carry out determining apart from sequence number whether the address of processing is final address ((i, j)=(0,1)), in the situation of final address, in step S46, drive horizontally rotating with motor 44 and vertical rotary of ultrasonic sensor 32 to use after the preset processing of motor 46, complete program.In addition, this preset processing is due to identical with the preset processing of carrying out in step S31, so its explanation is omitted.

On the other hand, in step S45, when being judged to be not to be final address, in step S47, driving and horizontally rotate with motor 44 and motor 46 for vertical rotary, ultrasonic sensor 32 is shifted to next address, return to step S35.

In addition, in step S39, when being judged to be interference, measurement data under (now) address can not be used at that time, so in step S41, will be accommodated in former range data in first substrate 48 as range data (measurement data is not upgraded) at that time, in step S48, for example, after the standby stipulated time (0.8s), shift to step S47.

; according to there being glitch-free result of determination to determine whether the result of determination of regeneration barrier object location detection part; thereby can carry out exactly the range measurement apart from barrier; control as described later wind direction and change parts so that air conditioning wind avoid-obstacles, thereby can make air conditioning efficiency improve.

In addition, in step S48, being set the stand-by period, is in order to make the total elapsed time in each address roughly certain.That is, in noisy situation, do not carry out the processing of step S40, S42, S43, S44, so if the stand-by period is not set,, compared with glitch-free situation, elapsed time shortens, the action meeting of ultrasonic sensor 32 is nature not.In addition, by scanning whole Obstacle Position critical regions and so that roughly certain mode control obstacle detector of the total elapsed time in each address, thereby can give occupant with the sense of feeling at ease.

Then, the distance sequence number in the transmission processing in description of step S42, reception & disposal, step S44 in step S43 is determined processing in turn, but first about describing for " apart from sequence number ".

" apart from sequence number " means the approximate distance of a certain position P from ultrasonic sensor 32 to living space, as shown in figure 20, ultrasonic sensor 32 is arranged on apart from ground 2m top, distance using ultrasonic sensor 32 to position P is as " apart from sequence number reasonable time ultrasonic wave arrive distance ", and position P is expressed from the next.

X=arrives distance × sin (90-α)

Y=2m-arrives distance × sin α

In addition, the barrier supposition such as the desk of obstruction Air Flow or sofa are positioned at apart from the height of ground 0.4～1.2m, and the position of barrier can determine according to the angle of depression α apart from indoor set with apart from sequence number (range information).

In addition, apart from sequence number, adopt 2～12 integer value, be equivalent to each ultrasonic wave apart from sequence number and transport the setting as shown in table 7 of reciprocal time.

[table 7]

In addition, table 7 represents to be equivalent to the position of each position P apart from sequence number and angle of depression α, with the part of ordinate, represents that Y forms negative value (Y < 0), enters the position on ground.In addition, the setting of table 7 is to be applicable to the air conditioner of ability rating 2.2kw, this air conditioner is as the air conditioner of specializing in the room (diagonal distance=4.50m) of being located at 6 tatamis, to set as limits value (maximum X) apart from sequence number=6.; in the room of 6 tatamis, with the position suitable apart from sequence number >=7 be diagonal distance > 4.50m, form the position (position in the outside in room) of wall that exceedes room; be complete nonsensical distance sequence number, by horizontal line, represented.

Therefore, table 8 is the air conditioners that are applicable to ability rating 6.3kw, this air conditioner is as the air conditioner of specializing in the room (diagonal distance=8.49m) of being located at 20 tatamis, to set as limits value (maximum X) apart from sequence number=12.

[table 8]

Shadow part:

enter the part on ground

Table 9 represents and the ability rating of air conditioner and the limits value of the distance sequence number of each corresponding setting of vertical direction position j roughly.

[table 9]

In addition, due to apart from thering is amplitude on hyperacoustic shipping time corresponding to sequence number, so keep certain width (error), table 10 to represent the relation of the distance sequence number that is identified and actual distance with the actual distance corresponding apart from sequence number.

[table 10]

Then,, about the reception & disposal in the transmission processing in step S42 and step S43, with reference to the sequential chart of Figure 21, describe.

As ultrasonic wave transmitted signal, as mentioned above, for example, with 2ms, send the signal of the 50kHz of 50% dutycycle, after 100ms, again send ultrasonic wave transmitted signal, and repeatedly carry out, in each address, send the ultrasonic wave transmitted signal that adds up to 8 times.In addition, as measuring interval, to set 100ms be because time interval of 100ms is the time that can ignore the impact on back wave of transmission processing last time.

In addition, the output token time is for example set as 8ms, before the 8ms of output ultrasonic wave transmitted signal, export the reception marking signal of L rank, ultrasonic wave while guaranteeing to send receives the H rank of signal, and from output token signal between the output process 8ms of ultrasonic wave transmitted signal, thereby remove the interference such as after-sound signal.In addition, ultrasonic wave receives the input processing (from the output of latch circuit 60) of signal, processes similarly with above-mentioned Interference Detection, and for example every 4ms carries out.

In addition, whenever the transmission of ultrasonic wave transmitted signal, in every 4ms, read repeatedly this signal rank, in order to prevent from disturbing waiting, cause misinterpretation, twi-read is unanimously in the situation of L rank, using the value (N-1) that deducts 1 gained from counting N as apart from sequence number (ultrasonic wave transports the reciprocal time).In the example of Figure 21, send after ultrasonic wave transmitted signal, the output signal of comparing section 58 is L rank (receiving marking signal is H rank) between N=5 and N=6, so it o'clock is H rank in N=0～5 that ultrasonic wave receives signal, N=6, within 7 o'clock, be L rank, when twi-read is unanimously N=7 for L rank, apart from sequence number, being N-1=6, is 6 × 4ms=24ms in the reasonable time of apart from sequence number.

Then, about the distance sequence number in step S44, determine that processing describes.

As mentioned above, apart from setting limits value according to the vertical direction position j of the ability rating of air conditioner and each address in sequence number, it is in the situation of N > maximum X that ultrasonic wave receives signal, if twi-read is not unanimously L rank, and also setpoint distance sequence number=X.

In each address (i, j), determine the distance sequence number of 8 times points, from a large side, remove in turn three and remove in turn three apart from sequence number apart from sequence number and from a little side, get two mean values apart from sequence number of residue, determine apart from sequence number.In addition, mean value removes below decimal point, rounds numerical value, and the ultrasonic wave that is equivalent to so definite distance sequence number transports the reciprocal time and records as table 7 or table 8.

In addition, in the present embodiment, in each address, determine that eight apart from sequence number, remove each three of size and get two mean values apart from sequence number of residue apart from sequence number, determine apart from sequence number, but the distance sequence number determining in each address is not limited to eight, the distance sequence number of averaging is also not limited to two.

In addition, apart from the range measurement of the barriers such as furniture, when the running of air conditioner stops, carrying out, while stopping about the running of this air conditioner, apart from the range measurement of barrier, with reference to the flow chart of Figure 22, carry out ensuing explanation.In addition, the flow chart of Figure 22, due to extremely similar with the flow chart of Figure 18, so different steps is only described below.

When the running of air conditioner starts, in step S34, to horizontally rotate and be set in target primary position ((i with motor 44 and vertical rotary motor 46, j)=(0,0)), and when the running of air conditioner stops, in step S54, to horizontally rotate and be set in target primary position ((i, j)=(0,2)) with motor 44 and vertical rotary motor 46.

Similarly, when the running of air conditioner starts, in step S45, judge and carry out determining apart from sequence number whether the address of processing is ((i, j)=(0, final address, 1)), and when the running of air conditioner stops, in step S66, judge and carry out determining apart from sequence number whether the address of processing is final address ((i, j)=(0,15)).

The distance apart from barrier when the running of air conditioner stops, the most different step S60 that are owing to starting from running, in step S59, noiseless when being judged to be, in step S60, be judged to be with address (i at that time, j) in corresponding region (the region A～G shown in Fig. 5 is as following) nobody's situation, shift to step S61, on the other hand, in the situation that being judged to be people, shift to step S62.; because people is not barrier; so set by this way; in the address corresponding with the region that is judged to be people; do not carry out range measurement; range data (not upgrading range data) before using, only carries out range measurement in the address corresponding with the region that is judged to be nobody, uses the new range data (renewal range data) of measuring.

; in each Obstacle Position critical region, carry out having or not while judging of barrier; corresponding to the result of determination whether someone exists in the people position critical region corresponding with each Obstacle Position critical region; determine whether upgrade the result of determination of the obstacle detector in each Obstacle Position critical region, thereby carry out efficiently the judgement that has or not of barrier.More specifically, belonging in the Obstacle Position critical region of people position critical region that is judged to be nobody by human body detection device, by the result of determination last time of new result of determination regeneration barrier thing checkout gear, and belonging in the Obstacle Position critical region of people position critical region that is judged to be people by human body detection device, can't help the result of determination last time of new result of determination regeneration barrier thing checkout gear.

In addition, in step S62 in step S41 in the flow chart of Figure 18 or the flow chart of Figure 22, range data before using, but the data before not existing after air conditioner assembling, so utilize obstacle detector being judged to be in each Obstacle Position critical region to Use Defaults first, value is used above-mentioned limits value (maximum X) by default.

In addition, in the flow chart of Figure 18 or the flow chart of Figure 22, suppose that barrier is positioned at apart from the height of ground 0.4～1.2m, the position of barrier determines according to the angle of depression α apart from indoor set and range information (determine and process apart from sequence number), but in each address, only detect the having or not of barrier, range information is dispensable.

Therefore, replace the range measurement in step S40, the S44 of flow chart of Figure 18 and step S61, the S65 of the flow chart of Figure 22 process and determine and process apart from sequence number, according to the distance apart from indoor set, set the mark time, be determined with the situation of clear, with reference to Figure 23 and table 11～13, describe.

[table 11]

[table 12]

[table 13]

; two threshold values (0.4m, 1.2m) are set on the height apart from ground; according to the distance apart from indoor set, each address is set as shown in Figure 23 and table 11 (at a distance), table 12 (middle distance), table 13 (closely) the mark time of two acquiescences corresponding with two threshold values; during serving as a mark before mark time t1 and than its long mark time t2, marking signal is exported to obstacle detector later.In addition, using during being clipped by mark time t1 and mark time t2 as can reception period (between luxuriant and rich with fragrance mark phase), only in the situation that can reception period responding, (ultrasonic sensor 32 receives back wave, there is barrier this position, in each address, send and add up to eight ultrasonic wave transmitted signals, in can reception period, have reaction more than stated number and be judged to be barrier.

In addition, as used herein for " at a distance ", " distance ", " closely " distance based on apart from indoor set as to give a definition.

Closely: region A

Middle distance: region B, C, D

Remote: region E, F, G

In addition, as mentioned above, the distance B from ultrasonic sensor 32 to barrier by

D=Ct/2 ... (1) represent,

But velocity of sound C depends on temperature, if establish temperature, be T, the velocity of sound C under 1 atmospheric pressure by

C=331.5+0.61T represents.

Therefore, when two mark times setting according to angle of depression α, according to temperature, change, while being determined with clear, detection of obstacles precision further improves.

Therefore, the mark time shown in Figure 23 and table 11～13 is the mark time of indoor temperature (inlet temperature of indoor set) T while being 10 ℃≤T≤30 ℃, when the mark time in the situation of 10 ℃ of T <, can as shown in Figure 24 and table 14～16, set, the mark time in the situation that T > is 30 ℃ can be set as shown in Figure 25 and table 17～19.

[table 14]

[table 15]

[table 16]

[table 17]

[table 18]

[table 19]

In addition, velocity of sound C also depends on air pressure, and table 20 represents the relation of the error of air pressure in situation that the distance from ultrasonic sensor to object is 1～8m and distance.At this, if air pressure is P, the every 1m of the distance from ultrasonic sensor to object produces the error of about 53.75 (1-P) cm, so described error in addition on the mark time of calculating in use formula (1), the corresponding air pressure correction velocity of sound, thus detection of obstacles precision further improves.

[table 20]

In addition, detection of obstacles precision is also subject to the impact that height is set of indoor set (in fact, ultrasonic sensor 32), and by considering the height that arranges of indoor set, detection of obstacles precision further improves.; suppose arranging highly for the height of 2m is set the mark time of indoor set; still consider; indoor set is arranged on apart from ground in the locational situation lower than 2m; can be using the groove on ground etc. as detection of obstacles; and indoor set is arranged on apart from ground in the locational situation higher than 2m, can't detect barrier completely.

Therefore, the indoor set height switching part (button, switch etc.) of " standard ", " reduction ", " raising " is set in the remote controller (interval operation device far away) of interval operation air conditioner far away or indoor set main body, when the arranging of indoor set, corresponding its highly switches indoor set height switching part, thereby prevents the error detection highly causing because of arranging of indoor set.

Figure 23, Figure 24, Figure 25 represent the situation of height apart from ground 2m that arrange of indoor set, but indoor temperature T be 10 ℃≤T≤30 ℃, indoor set height is set in the situation of ground 1.7m, the mark time can be set as shown in Figure 26 and table 21～23, indoor set arrange height in the situation of ground 2.4m, the mark time can be set as shown in Figure 27 and table 24～26.In addition, in the situation that the situation that T < is 10 ℃ and T > are 30 ℃, the also variation of the corresponding velocity of sound based on variations in temperature and setting.

[table 21]

[table 22]

[table 23]

[table 24]

[table 25]

[table 26]

Therefore, by indoor set arrange height apart from the mark time in the situation of ground 2m ± 0.2m, 1.7m ± 0.2m, 2.4m ± 0.2m and " standard ", " reduction " set by indoor set height switching part, " raising ", distinguish corresponding, thereby can eliminate the error detection that arranging of indoor set highly causes.

In addition, in table 21～26, mark time t1 and mark time t2 are set as the angle of depression meaning of identical time and do not carry out detection of obstacles.

In addition, indoor set owing to being arranged on the height of " standard " more, so on the height of " standard ", the mark time of use based on indoor temperature, and on the height of " reduction " and " raising ", as indoor temperature, can ignore the situation of 30 ℃ of the situation of 10 ℃ of T < or T >, use the mark time of 10 ℃≤T≤30 ℃.

Figure 28 represents for so setting the mark time and selecting to ignore the flow chart of the mark time in the situation of effects of air pressure.

In step S71, before preset processing, detect indoor temperature, in step S72, judge that highly whether the arranging of indoor set of being set by remote controller be " standard ", in the situation of " standard ", shift to step S73, rather than " standard " and situation under, shift to step S78.

In step S73, judge whether indoor temperature T is 10 ℃≤T≤30 ℃, when in the situation of 10 ℃≤T≤30 ℃, in step S74, select the mark time of Figure 23, rather than in the situation of 10 ℃≤T≤30 ℃, in step S75, determine whether it is 10 ℃ of T <.The in the situation that of 10 ℃ of T <, in step S76, select the mark time of Figure 24, rather than in the situation of 10 ℃ of T <, because indoor temperature T becomes 30 ℃ of T >, so in step S77, select the mark time of Figure 25.

In addition, in step S78, judge highly whether the arranging of indoor set of being set by remote controller be " reduction ", in the situation of " reduction ", in step S79, select the mark time of Figure 26, not in the situation of " reduction ", because arranging highly of the indoor set of being set from remote controller becomes " raising ", in step S80, select the mark time of Figure 27.

At this, when paying close attention to the height of barrier, in the control of air-flow, particularly particularly important for the height of nearby region disturbance in judgement thing.For example, when heating, if highly low barrier, conventionally by automatic wind, to controlling (aftermentioned), how many upper lower panels 12 is set upward, on barrier, send air-flow, can carry out comfortable air conditioning, and have in the situation of highly high barrier, when upper lower panel 12 is set upward in order to avoid this barrier, air-flow can not arrive ground or heating installation directly blows to occupant face, can bring unplessantness displeasure to occupant, so in the case of the highly high barrier of avoidance, it is effective making left and right fin 14 swagger pendulum work (aftermentioned).By judgement like this, be present in the height of indoor barrier, can realize comfortable air conditioning space.

Therefore, three threshold values (for example 0.4m, 0.7m, 1.2m) are set in the height apart from ground, the barrier that is 0.7～1.2m by the height apart from ground is defined as " high obstacle thing ", the barrier that is defined as 0.4～0.7m apart from the height on ground is defined as to " low obstacle ", for nearby region, set high obstacle quality testing and survey the mark time of use and the mark time of low obstacle detection use,, also can carry out two stage detection.

Particularly, about remote region and middle distance areas, the height sub-area of barrier is divided into one (0.4～1.2m), use the mark time of Figure 23～Figure 27, in each address, send the ultrasonic wave transmitted signal that adds up to 8 times, that carries out barrier has or not judgement (with reference to Figure 21), about nearby region, the height sub-area of barrier is divided into two, in each address of nearby region, use the mark time shown in Figure 29 or table 27, send the ultrasonic wave transmitted signal that adds up to 8 times, carry out the judgement that has or not of high obstacle thing, re-use afterwards the mark time shown in table 28, send the ultrasonic wave transmitted signal that adds up to 8 times, carry out the judgement that has or not of low obstacle.

[table 27]

[table 28]

In addition, about remote region and middle distance areas, also the height sub-area of barrier is divided into two, sets the survey of high obstacle quality testing and detect and use the mark time with mark time and low obstacle, carry out two stage detection of obstacles.

In addition, also can with upper threshold value, the height of barrier be divided into more than three four of the height settings apart from ground, still preferably more approach the region of indoor set, more increase the height number of partitions of barrier.

Therefore, arranging of the mark time representation indoor set of Figure 29, table 27 and table 28 is highly " standard ", indoor temperature T is the situation of 10 ℃≤T≤30 ℃, indoor temperature T is 10 ℃ of T <, in each address of nearby region, detects " high obstacle thing ", use the mark time shown in Figure 30 or table 29, carry out the judgement that has or not of high obstacle thing, the mark time shown in table 30 that re-uses is afterwards carried out the judgement that has or not of low obstacle.

[table 29]

[table 30]

In addition, when indoor temperature T is 30 ℃ of T >, in each address of nearby region, detect " high obstacle thing ", the mark time shown in Figure 31 or table 31 of using is carried out the judgement that has or not of high obstacle thing, re-use afterwards the mark time shown in table 32, carry out the judgement that has or not of low obstacle.

[table 31]

[table 32]

In addition, arranging of indoor set is highly in the situation of " reduction ", indoor temperature T is in the situation of 10 ℃≤T≤30 ℃, use the mark time of Figure 32 and table 33, table 34, indoor temperature T is in the situation of 10 ℃ of T <, the mark time of using Figure 33 and table 35, table 36, indoor temperature T is in the situation of 30 ℃ of T >, uses the mark time of Figure 34 and table 37, table 38.

[table 33]

[table 34]

[table 35]

[table 36]

[table 37]

[table 38]

In addition, arranging of indoor set is highly in the situation of " raising ", indoor temperature T is in the situation of 10 ℃≤T≤30 ℃, use the mark time of Figure 35 and table 39, table 40, indoor temperature T is in the situation of 10 ℃ of T <, the mark time of using Figure 36 and table 41, table 42, indoor temperature T is in the situation of 30 ℃ of T >, uses the mark time of Figure 37 and table 43, table 44.

[table 39]

[table 40]

[table 41]

[table 42]

[table 43]

[table 44]

In addition, in Figure 29～Figure 37 or table 27～44, high obstacle quality testing survey with can reception period and low obstacle detect with can reception period overlapping and set, but according to the study control of detection of obstacles described later, if point high obstacle thing and low obstacle carry out detection of obstacles in an orientation, even if have barrier in this orientation, be also likely judged to be clear, so it is consistent with high obstacle quality testing survey mark time t1 to make low obstacle detect with mark time t1.In this case, low obstacle detects uses the mark time only as low obstacle, to judge, high obstacle quality testing is surveyed and used the mark time judge and also as low obstacle, judge as high obstacle thing.

In addition, as shown in Figure 23～37, on the address of measuring, are set two mark times, detection is positioned in the situation of the barrier of the height of ground 0.4～1.2m, the angle of depression of measuring in middle distance areas, with at the angle of depression of remote or close-in measurement, overlap, in the angle of depression that is equivalent to middle distance areas, to each address change mark time, carry out twice sweep.

In addition, in the present embodiment, when the running that detection of obstacles is divided into air conditioner starts and while stopping, carrying out, but in the running of compressor and indoor blower, electrical Interference and noise around bring harmful effect can to ultrasonic sensor 32, so the detection of obstacles of the ultrasonic sensor 32 in whole addresses can be carried out when the running of air conditioner stops.

In addition, moment set parts is set on remote controller, can controls in the moment of being set by moment set parts the detection of obstacles of ultrasonic sensor 32.In this case, in the case of in the moment of being set by moment set parts, work as air conditioner in running, do not start detection of obstacles, and in stopping, start detection of obstacles in the case of in moment of being set by moment set parts when compressor or indoor fan 8.

In addition, on the basis of the detection of obstacles under the above-mentioned moment (arrangement of time (timing)), for the testing result of ultrasonic sensor 32 being reflected in the running of air conditioner, also the interference of surrounding environment can be had no regard for, when the running of air conditioner starts, start the detection of obstacles of whole addresses.

In addition, ultrasonic sensor 32 sends ultrasonic wave using air as medium, receive its back wave, there iing air-flow where, likely can not carry out the position probing of barrier accurately, so carry out detection of obstacles the set angle of the each address change left and right fin 14 shown in corresponding table 5 in the running of indoor fan 8.

In detail, in the running of indoor fan 8, angle beta is in the horizontal direction while utilizing ultrasonic sensor 32 to carry out detection of obstacles in each address of 10 degree～55 degree, with angle of depression α independently, left and right fin 14 is observed towards the situation of left setting (detection side of ultrasonic sensor 32 to) from indoor set, left and right fin 14 is changed towards front, and left and right fin 14, towards front or in the situation of right setting, does not change the direction initialization of left and right sheet 14.

In addition, angle beta is in the horizontal direction while utilizing ultrasonic sensor 32 to carry out detection of obstacles in each address of 60 degree～115 degree, with angle of depression α independently, left and right fin 14 is observed towards front and is set the situation of (detection side of ultrasonic sensor 32 to) from indoor set, by left and right fin 14 towards left or towards right change, left and right fin 14, towards a left side or in the situation of right setting, does not change the direction initialization of left and right sheet 14.

In addition, the angle beta of making horizontal direction is while utilizing ultrasonic sensor 32 to carry out detection of obstacles in each address of 120 degree～170 degree, with angle of depression α independently, left and right fin 14 is observed towards the situation of right setting (detection side of ultrasonic sensor 32 to) from indoor set, left and right fin 14 is changed towards front, left and right fin 14, in situation left or that set towards front, does not change the direction initialization of left and right sheet 14.

In addition, when the people position critical region shown in Fig. 5 is divided into left region (region A, B, E), middle section (region A, C, F), right region (region A, D, G) from indoor set observation, Obstacle Position critical region shown in Figure 14 is observed and is divided into left region (orientation A1, B1, B2, E1, E2), middle section (orientation A2, C1, C2, F1, F2), right region (orientation A3, D1, D2, G1, G2) from indoor set, and the angular range of above-mentioned horizontal direction is corresponding with region below respectively.

Angle beta: 10 degree～55 degree → left regions

Angle beta: 60 degree～115 degree → middle sections

Angle beta: 120 degree～170 degree → right regions

; in the running of indoor fan 8; left and right fin 14 towards the detection side of ultrasonic sensor 32 to situation under; by by left and right fin 14 towards to changing to different directions from the detection side of ultrasonic sensor 32, thereby can do one's utmost to reduce the impact of the detection of obstacles of air-flow on ultrasonic sensor 32.More specifically, will carry out the region of air conditioning observes and is divided into the situation in multiple regions of left and right directions from indoor set, left and right fin 14 in the situation of the surveyed area of ultrasonic sensor 32, by left and right fin 14 towards change to towards with the region of the surveyed area adjacency of ultrasonic sensor 32.

In addition, ultrasonic sensor is when the detection of obstacles in left region, left and right fin 14 is observed towards the situation of left setting from indoor set, or ultrasonic sensor is when the detection of obstacles in right region, left and right fin 14 is observed towards the situation of right setting from indoor set, by left and right fin 14 respectively towards right or towards left change, by left and right fin 14 towards changing to towards the region away from the surveyed area of ultrasonic sensor, can further reduce the impact of air-flow.

In addition, make the detection of obstacles of ultrasonic sensor preferential on the blow-off direction of air conditioner, thereby comfortableness can how many reduce, but change in the situation of direction initialization of left and right fin 14, the moment completing in the detection of obstacles of ultrasonic sensor 32, by left and right fin 14 towards return to before changing towards upper, thereby can do one's utmost to suppress the reduction of comfortableness.

In addition, carry out the running of air conditioner at every turn, as shown in table 6, while carrying out detection of obstacles on region-wide, because the detection of obstacles performance of also considering ultrasonic sensor 32 reduces, so region-wide detection is only carried out once after first running and memory replacement (replacement of second memory described later), later detection for the second time also can be carried out 1/3 region at every turn.

; detect for the second time and carry out belonging in the orientation A1 in left region, B1, B2, E1, E2; detect for the third time and carry out belonging in the orientation A2 of middle section, C1, C2, F1, F2; detect for the 4th time and carry out belonging in the orientation A3 in right region, D1, D2, G1, G2, in 1/3 region, carry out similarly detection of obstacles the 5th time later.

Particularly, once region-wide detection and a 1/3 region detection are undertaken by order below.

Region-wide detection: E1 → E2 → B1 → B2 → A1 → F1 → F2 → C1 → C2 → A2 → G1 → G2 → D1 → D2 → A3

Left 1/3 region is detected: E1 → E2 → B1 → B2 → A1

Central authorities are detected in 1/3 region: F1 → F2 → C1 → C2 → A2

Right 1/3 region is detected: G1 → G2 → D1 → D2 → A3

In addition, people position critical region shown in Fig. 5 is observed and can be divided into a left side, central authorities, right three regions from indoor set, but with form human body detection device sensor unit quantity accordingly, people position critical region is observed and also can be divided into Liang Ge region, left and right or more than four region from indoor set, in this case, later detection is for the second time each forms 1/2 region or 1/R region (R >=4).

In addition, by reduction, there is the detection of obstacles frequency in the region that people's frequency is low, can further suppress the reduction of the detection of obstacles performance of ultrasonic sensor 32.

; according to the flow chart definite area characteristic (or life subregion) of Fig. 6 before; or previous specified time limit (for example one week) is stablized in the study control (aftermentioned) of detection of obstacles; with the frequency that has a people independently; detection of obstacles is carried out in every 1/3 region in turn; after specified time limit, for example, also can sample detection (pulling detection) according to region characteristic.

; from indoor set, observe; when being contained in region characteristic minimum in the region characteristic of the many individual positions critical region in a left side, central authorities, right three regions as the region characteristic in this region; this region is in the situation of region characteristic III, and the Obstacle Position in this region for example detects, with proportional spacing sampling once in repeatedly (5 times) and carries out.

For example, in left region, the region characteristic of region A, region B and region E is all in the situation of III, minimum region characteristic is III, so left region forms region characteristic III, the region characteristic in middle section and right region forms in the situation of I or II, carries out following interval sampling and detects.In addition, carry out interval sampling detection region characteristic before and determine that previous scanning times is set as seven times.

Wall (the 7th time) → left side (the 7th time) → central authorities' (the 7th time) → right side (the 7th time) → wall (the 8th time) → central authorities' (the 8th time) → right side (the 8th time) → wall (the 9th time) → ... → wall (the tenth once) → central authorities' (the tenth once) → right side (the tenth once) → wall (the 12 time) → left side (the 8th time) → central authorities' (the 12 time) → right side (the 12 time) →

In addition, in middle section, for example region A is region characteristic III, and region C is that region characteristic II, region F are in the situation of region characteristic III, and minimum region characteristic is II, so middle section is region characteristic II, does not carry out interval sampling and detects.

The study control > of < detection of obstacles

Ultrasonic sensor 32, conventionally the face angulation of its direction of illumination and object is can measure exactly before and after 90 degree, and along with this angle diminishes, the establishment that back wave returns to ultrasonic sensor 32 reduces gradually, the possibility of detection of obstacles failure improves.

As an example, the desk such as smooth dining table above considering, on desk without any article in the situation that, transmission ripple from ultrasonic sensor 32 radiates on desk, the possibility of returning to ultrasonic sensor 32 is extremely low, the determining positions difficulty of desk, and while there is daily necessities (tableware, remote controller, books, newspaper, paper towel box etc.) on desk, transmission ripple from ultrasonic sensor 32 is radiated and is returned to ultrasonic sensor 32 by desk and daily necessities, and it is easy that the determining positions of desk becomes.

Therefore, in this study control, detection of obstacles is not only to barrier, also utilizes and the interaction of spin off that is positioned near surrounding barrier.But, in fact be placed on furniture in room etc. (be in fact furniture, not equal to be the daily necessities being placed on furniture) possibility that every day, its place changed is very greatly, near the interaction of surrounding's spin off angle, the barrier of barrier changes, so by repeatedly carrying out detection of obstacles, can do one's utmost to reduce detection mistake.This study control, shown in flow chart as shown in figure 38, take each scanning result as basic learning Obstacle Position, controls the place at result disturbance in judgement thing place according to its study, carry out air-flow control described later.

Figure 38 represents that barrier has or not the flow chart of judgement, and this barrier has or not judgement to carry out in turn the whole orientation shown in Figure 14 (Obstacle Position critical region).At this, as an example of orientation A1 example, describe.

By ultrasonic sensor 32, start detection of obstacles action, first in step S81, in the initial address of orientation A1, by ultrasonic sensor 32, detect action (scanning), in step S82, that carries out above-mentioned barrier has or not judgement (reaction of time t1～t2 have or not judgement).In step S82, when being judged to be barrier, in step S83, to being located at the first holder " 1 " in addition on the 3rd substrate 52, when being judged to be there is no barrier, in step S84, to first memory " 0 " in addition.

In step S85, judge whether the detection of the final address of orientation A1 completes, in the uncompleted situation of detection of final address, in step S86, in next address, by ultrasonic sensor 32, detect action, return to step S82.

On the other hand, in the situation that the detection of final address completes, in step S87, be stored in numerical value (being judged to be the total of the address of barrier) in the first memory number of addresses (carrying out division arithmetic) divided by orientation A1, in following step S88, by the threshold value comparison of its business and regulation.When in business's situation larger than threshold value, in step S89, be temporarily judged to be has barrier in orientation A1, in step S90, to second memory " 5 " in addition.On the other hand, when in the situation of business less than threshold value, in step S91, be temporarily judged to be does not have barrier in orientation A1, in step S92, to second memory " 1 " (deducting " 1 ") in addition.

In addition, by ultrasonic sensor 32, the distance from ultrasonic sensor 32 to barrier more detection of obstacles is more difficult, so threshold value is for example set as follows according to the distance apart from indoor set as used herein.

Closely: 0.4

Middle distance: 0.3

Remote: 0.2

In addition, during the each running of this detection of obstacles action air conditioner, carry out, so on second memory in addition " 5 " or " 1 " repeatedly.Therefore, the numerical value being stored in second memory is set as maximum " 10 ", and minimum of a value is set as " 0 ".

Then, in step S93, judge that the numerical value (total after add operation) that is stored in second memory is whether for example, as more than determinating reference value (5), if determinating reference value, in step S94, final decision has barrier in orientation A1, if less than determinating reference value, in step S95, final decision does not have barrier in orientation A1.

In addition, first memory is when completing the detection of obstacles action in a certain orientation, remove this memory, thereby the memory that can serve as the detection of obstacles action in ensuing orientation uses, the air conditioner but second memory turns round at every turn, the addition calculated value (but maximum >=total >=minimum of a value) in an orientation of accumulation, so the memory of the quantity such as preparation and orientation number.

In the study control of above-mentioned detection of obstacles, as determinating reference value, set " 5 ", in the first detection of obstacles in a certain orientation, final decision has barrier, storage " 5 " in second memory.Under this state, if in upper detection of obstacles once final decision clear, due to " 5 " in addition the value of " 1 " gained less than determinating reference value, so there is not barrier in this orientation.

But, in next detection of obstacles also final decision when having barrier, " 5 " in addition the value " 10 " of " 5 " gained are stored in second memory, because aggregate value is more than determinating reference value, be judged to be to have barrier in this orientation, even if be judged to be clear in the detection of obstacles of later 5 times lower next time, due to " 10 " in addition the value of " 1 × 5 " gained be " 5 ", so still there is barrier in this orientation.

, the study control of this detection of obstacles has such feature: according to addition accumulated value (or addition and subtraction accumulated value) repeatedly carry out barrier finally have or not judge time, the value adding while being judged to be barrier is set as subtracting when being judged to be clear the fully large numeral of value of calculation, by setting like this, can easily draw the result of barrier.

In addition, by the numerical value being stored in second memory, maximum and minimum of a value being set, thereby even because of removal of home or change looks etc. and make the larger variation in position of barrier, can try one's best and follow fast this variation.Do not arrange in peaked situation, while being judged to be barrier at every turn, itself and become gradually large, the position of barrier changes because moving etc., barrier leaves on the region that is at every turn judged to be barrier, lower than determinating reference value, also needs spended time.In addition, do not arrange in the situation of minimum of a value, produce contrary phenomenon.

Figure 39 represents the variation of the study control of the detection of obstacles shown in the flow chart of Figure 38, because only the processing of step S110, S112, S113 is different with the flow chart of Figure 38, so describe about these steps.

In this study control, in step S109 when being temporarily judged to be to have barrier in orientation A1, in step S110 to second memory " 1 " in addition.And in step S111, while being temporarily judged to be in orientation A1 clear, in step S112, to second memory " 0 " in addition.

Then, in step S113, according to the past detection of obstacles of 10 times that comprises current detection of obstacles, for example, by being stored in aggregate value in second memory and determinating reference value (2), compare, if more than determinating reference value, in step S114, final decision is for there is barrier in orientation A1, and if less than determinating reference value,, in step S115, final decision is clear in orientation A1.

That is, the study control of above-mentioned detection of obstacles, even barrier can not be detected 8 times in the past in a certain orientation detection of obstacles of 10 times, if can detect for twice, final decision is for there being barrier.Therefore, this study control has such feature: final decision is that the detection of obstacles number of times (in this case twice) that has barrier is set as than fully little numeral of the detection of obstacles number of times in the past of reference, by setting like this, easily draw the result with barrier.

In addition, can on indoor set main body or remote controller, arrange resets is stored in the button of the data in second memory, by pressing this button described data of resetting.

Substantially, to air-flow control have the barrier of considerable influence or the change in location of wall few, but when in the situation of the change of the furniture position of the looks change in change or the room of setting position that follow indoor sets such as moving etc., it is undesirable based on the data that so far obtain, carrying out air-flow control.This is because controlled and can be formed the control that is applicable to this room by study, but needs spended time (remarkable the in the situation that of particularly there is no barrier in this region) to Optimal Control.Therefore, by replacement button is set, in the situation that the relative position relation of indoor set and barrier or wall changes, by the data of resetting so far, thereby can prevent the unsuitable air conditioning of carrying out based on the data of past mistake, and from again opening at first study, control, can obtain being as early as possible applicable to the control of its situation.

< obstacle avoidance control >

According to the judgement that has or not of above-mentioned barrier, as wind direction change the upper lower panel 12 of parts and left and right fin 14 when the heating as controlled below.

In the following description, use term " block (block) ", " field (field) ", first these terms are described.

Region A～G shown in Fig. 5 belongs to respectively following block.

Block N: region A

Block R: region B, E

Block C: region C, F

Block L: region D, G

In addition, region A～G belongs to respectively following field.

Field 1: region A

Field 2: region B, D

Field 3: region C

Field 4: region E, G

Field 5: region F

Table 45 represents to form the goal-setting angle in 5 left wing's sheets of left and right fin 14 and each orientation of 5 right flank sheets, mark in numeral (angle) as shown in figure 40, be defined as left wing's sheet or the right flank sheet direction that is just (+, in table 45 without mark) towards the situation of inner side, the direction that situation is toward the outer side negative (-).

[table 45]

In addition, " heating B region " in table 45 refers to the heating region of carrying out obstacle avoidance control, and " automatic wind is to controlling conventionally " refers to the wind direction control of not carrying out obstacle avoidance control.At this, whether carry out the judgement of obstacle avoidance control, take the temperature of indoor heat converter 6 as benchmark, in the low situation of temperature, carry out the wind direction control to heating B region in the situation of wind direction control, mild temperature of maximum quantity of wind position in risk control that wind do not blow to occupant, too high situation.In addition, in this so-called " temperature is low ", " too high ", " wind does not blow to occupant's wind direction control ", " the wind direction control of maximum quantity of wind position ", be the following meaning.

Low temperature: the temperature of indoor heat converter 6 is set take skin temperature (33～34 ℃) as optimum temperature, can become the temperature (for example 32 ℃) below this temperature

Excessive temperature: for example, more than 56 ℃

Wind does not blow to occupant's wind direction control: so that wind does not carry out angle control towards the mode of living space to upper lower panel 12, make the wind wind direction control mobile along roof

The wind direction control of maximum quantity of wind position: air conditioner certainly leads to impedance (loss) owing to making air-flow bending by upper lower panel 12 and left and right fin 14, so maximum quantity of wind position refers to that the wind direction control of loss infinite approach 0 is (in the situation of left and right fin 14, in the situation of the position of right opposite, upper lower panel 12, from level 35 spend towards position).

Table 46 represents to carry out the goal-setting angle in each field of the upper lower panel 12 in the situation of obstacle avoidance control.In addition, the angle (γ 2) of the angle of the upper panel in table 46 (γ 1) and lower panel be from horizontal line measure towards angle (angle of depression).

[table 46]

Then, about the obstacle avoidance control corresponding with the position of barrier, specifically describe, but first about the term using in obstacle avoidance control " rocking action ", " orientation stop work ", " square stop work ", describe.

Rocking action refers to by the rocking action of left and right fin 14, substantially centered by the orientation of one of target, with the left and right angle amplitude of regulation, waves, and there is no the action of set time at the two ends of waving.

In addition, orientation stop work refers to, the goal-setting angle (angle of table 45) to a certain orientation is carried out the correction of table 47, respectively as left end and right-hand member.As action, at left end and right-hand member, there is respectively the wind direction set time (time of fixing left and right fin 14), for example, the in the situation that of the left end process wind direction set time, to right-hand member, move, at right-hand member, through before the wind direction set time, maintain the wind direction of right-hand member, the wind direction set time through after, to left end, move, and repeatedly carry out.The wind direction set time is for example set as 60 seconds.

[table 47]

That is, the in the situation that of having barrier, use as former state the goal-setting angle in this orientation in a certain orientation, warm braw blows to barrier all the time, but by carrying out the correction of table 47, can make warm braw arrive from the side of barrier the position that has people.

In addition, so-called square stop work refers to, the set angle of the left and right fin 14 corresponding with the left end of each square and right-hand member for example determines according to table 48.As action, at left end and the right-hand member of each square, there is respectively the wind direction set time, for example at left end after the wind direction set time, to right-hand member, move, before the right-hand member process wind direction set time, maintain the wind direction of right-hand member, after wind direction set time warp, to left end, move, repeatedly so operate.The wind direction set time, with orientation stop work similarly, be for example set as 60 seconds.In addition, the left end of each square and right-hand member are consistent with left end and the right-hand member of people position critical region of being located at this square, so square stop work also can be called the stop work of people position critical region.

[table 48]

In addition, orientation stop work and square stop work are separately used according to the size of barrier.In the little situation of the barrier in front, centered by a certain orientation of barrier, carry out orientation stop work, thereby avoiding obstacles and blowing, with respect to this, it is large that the barrier in front becomes, for example there is the front entirety in people's region to have in the situation of barrier, carry out square stop work, thereby blow in wider scope.

In the present embodiment, general name rocking action, orientation stop work and square stop work are the rocking action of left and right fin 14.

Below, illustrate the control embodiment of lower panel 12 or left and right fin 14, but when judging that by human body detection device people is only in single region, by obstacle detector, judge in the case of being arranged in the Obstacle Position critical region that is judged to be the front of people's people position critical region by human body detection device have barrier, lower panel 12 in control, carries out the air-flow control from top avoid-obstacles.In addition, by obstacle detector, judge in the case of belonging to by human body detection device and be judged to be to have barrier in people's the Obstacle Position critical region of people position critical region, being chosen at least one the Obstacle Position critical region that belongs to the people position critical region that is judged to be people waves left and right fin 14, the first air-flow control and belonging to that the set time of left and right fin 14 is not set at the two ends of the scope of waving is judged to be at least one Obstacle Position critical region of people's people position critical region or the people position critical region adjacent with this region, left and right fin 14 to be waved, one of second air-flow control of the set time of left and right fin 14 is set at the two ends of the scope of waving.

In addition, in the following description, be divided into the control of lower panel 12 and the control of left and right fin 14, but can with the position of people and barrier accordingly, the control of the control of upper lower panel 12 and left and right fin 14 is appropriately combined to be carried out.

A. go up lower panel control

(1) in any of region B～G, there is people, in the orientation A1～A3 in front in region that has people, have barrier,

Carry out the set angle of upper lower panel 12 to revise with respect to common field wind direction control (table 46) is shown in table 49 the air-flow control that upper lower panel 12 is set upward.

[table 49]

(2) in any region of region B～G, there is people, in the region A in front in region that has people, do not have barrier (above-mentioned (1) in addition)

Conventionally carry out automatic wind to control.

B. left and right fin control

B1. region A (closely) has in people's situation

(1) in the A of region, do not have the orientation of barrier to have one

Centered by the goal-setting angle in orientation that there is no barrier and carry out to the left and right wobbling action, carry out the first air-flow control.For example, in orientation A1, A3, there is barrier, the in the situation that of there is no barrier in orientation A2, centered by the goal-setting angle of orientation A2 and carry out to the left and right wobbling action, the orientation A2 that there is no barrier is carried out to air conditioning, but owing to being not limited to nobody in orientation A1, A3, so by adding wobbling action, how many air-flows can be divided in orientation A1, A3.

Be described more specifically, according to table 45 and table 47, determine goal-setting angle and the angle correction (angle of oscillation during wobbling action) of orientation A2, so all centered by 10 degree, not stopping respectively in the angular ranges of ± 10 degree, left wing's sheet and right flank sheet continue shake (swing).But the arrangement of time that left wing's sheet and right flank sheet swing is set as identical, the shake action interlock of left wing's sheet and right flank sheet.

(2) in the A of region, there is no the orientation of barrier is two, in adjacent situation (A1 and A2 or A2 and A3)

Goal-setting angle using two orientation thering is no barrier is carried out wobbling action as two ends, carry out the first air-flow control, thereby air conditioning is carried out in the orientation that there is no barrier.

(3) in the A of region, there is no the orientation of barrier is two, in situation about leaving (A1 and A3)

Goal-setting angle using two orientation thering is no barrier is carried out square stop work as two ends, carry out the second air-flow control.

(4) in the A of region, in whole orientation, have in the situation of barrier,

Due to take where as target is as good not clear, institute is so that the second air-flow control is carried out in square N square stop work.This be due to, than target, be that region is all, square stop work is formed with the wind direction of directive property, easily arrives farly, possibility that can avoid-obstacles is higher.That is, even the in the situation that in the A of region, barrier disperseing, conventionally gapped between barrier and barrier, by the gap between this barrier, can blow.

(5), in the A of region, all in orientation, do not have in the situation of barrier

Carry out the common automatic wind of region A to control

B2. in any of region B, C, D (middle distance), have in people's situation

(1) only in the case of a side who belongs to two orientation that have people's region, have barrier

Centered by the goal-setting angle in two orientation that there is no barrier and carry out to the left and right wobbling action, carry out the first air-flow control.For example, in the D of region, there is people, the in the situation that of only having barrier in orientation D2, centered by the goal-setting angle of orientation D1 and carry out to the left and right wobbling action.

(2) in the case of the both sides that belong to two orientation that have people's region, have barrier

Make the square in the region that includes people carry out square stop work, carry out the second air-flow control.For example, in the D of region, there is people, in the situation that orientation D1, D2 both have barrier, make square L carry out square stop work.

(3) there is people's region not have in the situation of barrier

The common automatic wind in someone region is to control.

B3. in any of region E, F, G (at a distance), have people

(1) only on the side in two orientation of middle distance areas in front who belongs to the region that has people, have barrier and (for example: region E has people, on orientation B2, have barrier, in orientation B1, there is no barrier) '

(1.1) for example, the both sides in orientation that have barrier are adjacent while not having barrier (orientation B1, C1 do not have barrier)

(1.1.1) in the case of having, the both sides in orientation of barrier are adjacent does not have (for example in orientation E2, there is no barrier) barrier

Centered by the orientation that has barrier, carry out orientation stop work, carry out the second air-flow control.For example, in the E of region, there is people, in orientation B2, have barrier, in the situation that its both sides and rear all do not have barrier, can avoid being arranged in from side the barrier of orientation B2, air-flow is sent into region E.

(1.1.2) in the case of there being the rear in orientation of barrier to have barrier, (for example in orientation E2, there is barrier)

Centered by the goal-setting angle in orientation that there is no barrier in middle distance areas, carry out wobbling action, carry out the first air-flow control.For example, in the E of region, have people, in orientation B2, have barrier, in its both sides, there is no barrier, but have barrier at its rear in the situation that, never to send into air-flow be favourable to the orientation B1 of barrier.

(1.2) side in the both sides in orientation that have barrier are adjacent has barrier, in the situation that opposite side does not have barrier,

Centered by the goal-setting angle in orientation that there is no barrier, carry out wobbling action, carry out the first air-flow control.For example in the F of region, have people, in orientation C2, have barrier, in the adjacent middle orientation D1 in the both sides of orientation C2, have barrier, the in the situation that of there is no barrier in C1, the barrier that never the orientation C1 of barrier avoids orientation C2 by airflow feeding to region F.

(2) in both of two orientation of middle distance areas in front that belong to the region that has people, have barrier,

Make the square in the region that includes people carry out square stop work, carry out the second air-flow control.For example, in the F of region, there is people, in the situation that orientation C1, C2 both have barrier, make square C carry out square stop work.In this case, in people's front, have barrier, can not avoiding obstacles, so with in the square of adjacent square C, have clear irrelevant, carry out square stop work.

(3) in both of two orientation of middle distance areas in front that belong to the region that has people, there is no (for example: in the F of region, have people, in orientation C1, C2, there is no barrier) barrier

(3.1) only in the orientation of a side that belongs to two orientation that have people's region, have barrier,

Centered by the goal-setting angle in orientation of opposite side that there is no barrier, carry out wobbling action, carry out the first air-flow control.For example, in the F of region, there is people, in orientation C1, C2, F1, there is no barrier, the in the situation that of having barrier in orientation F2, because the front of the region F that has people is opened, so consider remote barrier, centered by the remote orientation F1 that there is no barrier, carry out air conditioning.

(3.2) in the case of belonging to have on both of two orientation in people's region, have barrier,

Make the square in the region that includes people carry out square stop work, carry out the second air-flow control.For example, in the G of region, there is people, in orientation D1, D2, there is no barrier, in the situation that orientation G1, G2 have barrier in both, the front of someone region G is open, but because this region has barrier on the whole, take where as target is as good indefinite, institute is so that square L carries out square stop work.

(3.3) in the case of belong to have both of two orientation in people's region in all barrier useless,

The common automatic wind in someone region is to control.

In addition, this obstacle avoidance control is judged and is controlled upper lower panel 12 and left and right fin 14 according to having or not of the barrier of the judgement whether someone exists of human body detection device and obstacle detector, but also can only according to the barrier of obstacle detector, have or not judgement to control upper lower panel 12 and left and right fin 14.

< is the obstacle avoidance control > that has or not judgement based on barrier only

This obstacle avoidance control is the region that is substantially judged to be barrier by obstacle detector for avoiding, and the control of the region air-supply that orientation judging is clear, below illustrates its concrete example.

A. go up lower panel control

(1) region A had in the situation of barrier in (closely)

Lighten when being suppressed at heating and heating installation on floating, make lower panel 12 when warm braw is sent in below, the in the situation that of having barrier in the A of region, warm braw rests on the back (indoor pusher side) of barrier, and heating installation is encountered barrier can not arrive ground.

Therefore, the in the situation that of barrier being detected under indoor set or near it, the set angle of upper lower panel 12 is revised with respect to common field wind direction control (table 46) is shown in table 49, carry out the air-flow control that upper lower panel 12 is set upward, on barrier, carry out air conditioning.Want avoid-obstacles and air-flow entirety is too upwards kicked up, heating installation directly blows to occupant face, brings unplessantness displeasure, so lower panel 12b holds up heating installation, and avoid-obstacles, and prevented from kicking up by upper panel 12a.

B. left and right fin control

(1) in any of region B, C, D (middle distance), have in the situation of barrier,

The wind direction that there is no barrier is carried out to emphasis air conditioning.For example, in the situation that region C (room central authorities) detects barrier, the square that makes to comprise region B, the D of the both sides that the there is no barrier square stop work that hockets, carries out emphasis air conditioning to the region that there is no barrier (=people's possibility is high).

In addition, at region B or D (corner in room), detect barrier, make the square of inclusion region C and D or region B and C carry out square stop work.In this case, for example, with ratio once in repeatedly (five times), region C and D or region B and C are carried out after square stop work, towards region B or D, left and right fin 14 is swung, the possibility that not only exists by people is carried out air conditioning centered by higher region, and aspect the air conditioning of room entirety, is being also effective.

In addition, the orientation having or not (Obstacle Position critical region) of differentiating barrier can be irrelevant with the ability rating of air conditioner, carry out as shown in figure 14 sectionalization, but because the size in the room corresponding and set from ability rating is also different, so can change cut zone number.For example, ability rating is 4.0kw when above, cuts apart as shown in figure 14, when 3.6kw is following, remote region can be set, and nearby region three is cut apart, and middle distance areas six is cut apart.

In addition, as shown in figure 14, with radial identification room, from indoor set be equally spaced divided into closely// at a distance in situation, more larger away from its area of indoor set.Therefore, by more more increasing critical region number away from indoor set, can make the size in each region roughly even, easily carry out air-flow control.

In addition, the full scan of living space sends ultrasonic wave by ultrasonic sensor 32 towards the each address shown in table 5 to carry out, but the angle intervals in the time of also can increasing scanning according to the distance from indoor set to critical region.

At this, if the detected cells territory corresponding with each address showed by " unit (cell) ", the detecting unit number in each region more increases, and accuracy of detection more improves, and still because sweep time is elongated, preferably takes into account accuracy of detection and sweep time.Therefore, for example, all spending and scan with every 10 with horizontal direction in closely corresponding each address (angle of depression α: 25 degree～80 degree) and vertical direction, lighten the each address corresponding with middle distance (angle of depression α: 15 degree～30 degree) and with remote corresponding each address (angle of depression α: 5 degree～20 degree) in horizontal direction and vertical direction all with every 5 degree, scan, thereby can make the detecting unit number roughly equal (roughly 20 spend front and back) in each region.

In addition, in table 5 and table 6, make to scan in ultrasonic sensor 32 scope that 5 degree～80 are spent in vertical direction, but by situation about setting as shown in Figure 23～Figure 27, Figure 29～Figure 37 for detection of the mark time having or not of barrier, angle of depression α is that the region of 70 degree～80 degree is owing to not carrying out the detection of barrier, so carry out in the scope of obstacle avoidance system below angle of depression α is 70 degree.

Action moment > in the situation of more than two indoor set is set in < mono-Room

When the indoor set of air conditioner is installed more than two in a room, these air conditioners roughly shut down conventionally simultaneously.When the running of air conditioner stops, carrying out in the situation of detection of obstacles of ultrasonic sensor 32, if the action moment of the detection of obstacles of each air conditioner is the same, the possibility of mutually interfering is higher.That is, if two above indoor sets are arranged in the orientation that can detect from the transmission sound of each ultrasonic sensor 32, a certain ultrasonic sensor 32 receives the ultrasonic wave sending from other ultrasonic sensors 32, and misidentification is made the transmission wave reflection ripple of self.

This is mutually interfered and can prevent by the action moment of each ultrasonic sensor 32 that staggers, mutually interfere and prevent from controlling by the pattern of plural ultrasonic sensor 32 is stored on first substrate 48, and pattern switching part (button, switch etc.) is set in remote controller or indoor set main body, suitably switch pattern, any of more than two pattern of selection carried out.

Its concrete example, as an example of following situation example, describe: two patterns of pattern A and pattern B are set, a ultrasonic sensor 32 in two indoor sets of one Room is set as to pattern A, and the ultrasonic sensor of another indoor set 32 is set as to pattern B.

Figure 41 represents the action moment of ultrasonic sensor 32, represents the example of each needed time of action in Figure 41.In addition, Figure 42 represents that pattern A adopts the action moment of Figure 41, and the situation of (the step S36 of Figure 18 or the step S56 of Figure 22) is stablized the stand-by period in pattern B change (growth).

As shown in figure 42, do not change the action moment pattern A air conditioner and change and stablize the stand-by period and change and move the air conditioner of pattern B in moment and roughly stop simultaneously, carry out in the situation of detection of obstacles of ultrasonic sensor 32, after air conditioner stops, the required time of range measurement of the time that the range measurement of the ultrasonic sensor 32 of the pattern that staggers A is required and the ultrasonic sensor 32 of pattern B, thus mutual interference can be avoided.But along with the operating distance measurement repeatedly in each address, the time that the range measurement of pattern A is required and required time of the range measurement of pattern B also can a part overlap, and also have the possibility of interference mutually occurs.

Figure 43 represents that pattern A adopts the action moment of Figure 41, and pattern B adopts how many changes (for example extending 1ms) to scan the situation of the time (stand-by period under first stand-by period or initial address) before starting.In this situation, if the scanning of the ultrasonic sensor 32 of two indoor sets starts simultaneously, in whole addresses, required time of the range measurement of pattern A and the required time of range measurement of pattern B can not overlap, and can avoid mutual interference.

But, when the air conditioner that is set as pattern B first stops than the air conditioner that is set as pattern A, the detection of obstacles of the ultrasonic sensor 32 of pattern B is carried out in advance than the detection of obstacles of the ultrasonic sensor of pattern A 32, and mutual interference also can occur.

Figure 44 represents that pattern A adopts the action moment of Figure 41, and pattern B adopts significantly prolongation setting (for example 20 minutes) to scan the situation of the time (first stand-by period) before starting.Particularly, pattern B sets longly by the scanning previous time that starts than the beginning from pattern A full actuation time to the end.That is, the poor of the first stand-by period of pattern A, B set longly than the beginning from each pattern full actuation time to the end.In this case, almost can avoid mutual interference, but the action of the ultrasonic sensor 32 of two indoor sets is greatly different.

Figure 45 adopts the action moment of Figure 41 as pattern A and pattern B, in the step S39 of Figure 18 or the step S59 of Figure 22, be judged to be in noisy situation, and the ultrasonic wave from ultrasonic sensor 32 of ending after this sends.In this structure, owing to being judged to be at first the noisy ultrasonic wave from air conditioner, send termination, so the detection of obstacles in other air conditioners is as conventionally carried out, can avoid mutual interference.

In addition, from the ultrasonic wave of ultrasonic sensor 32, send on the way and end, use the data that send before ending, in region under this unit, carry out the judgement that has or not of barrier, send and end later data defect, so the barrier in this region there is probability step-down, easily think by mistake and there is no barrier.Therefore, the discarded all data of newly obtaining in the barrier region that comprises damaged data, the data about this region with reference to the past, can avoid mistake identification.

In addition, in the scanning process of remote region → middle distance areas → nearby region, this data are used in the region of obtaining about the data that finish, and data in the past can be used in the region of obtaining about the data that do not finish.For example, in the unit scan of middle distance areas, detect in the situation of interference, about middle distance areas and nearby region, use data in the past.

In Figure 46, as pattern A and pattern B, all adopt the action moment of Figure 41, in the step S39 of Figure 18 or the step S59 of Figure 22, be judged to be in noisy situation, the ultrasonic wave from ultrasonic sensor 32 of ending now sends, how much postpone (for example 0.8ms), carry out once again Interference Detection processing, thereby can avoid mutual interference.

In the example of Figure 46, even carry out once again Interference Detection processing after postponing, when being judged to be interference, also can terminating in the ultrasonic wave from ultrasonic sensor 32 in this address and send, shift to next address.

In addition, in the present embodiment, as adopting ultrasonic type range sensor apart from detection part, but also can replace ultrasonic type range sensor, and adopt photo-electric range sensor.

(utilizability in industry)

Air conditioner of the present invention can shorten the detection time of barrier, and can do one's utmost the reduction of the detection of obstacles performance that suppresses ultrasonic sensor, so can use as the various air conditioners that comprise general home-use air conditioner.
