< structure of human body detection device >

As shown in Figure 1, on the top of front surface panel 4, a plurality of (for example three) fixed sensor unit 24,26,28 is installed as human body detection device, these sensor units 24,26,28 like Fig. 3 and shown in Figure 4, are kept by sensor stand 36.

Each sensor unit 24,26,28 comprises: circuit substrate, be installed on the camera lens of circuit substrate and be installed on the human body detection sensor of the inside of camera lens.In addition; Human body detection sensor; For example by whether having people's thermoelectric type infrared ray sensor to constitute, judge by circuit substrate whether the people is arranged based on the pulse signal of correspondingly exporting with the variation of the detected infrared ray amount of infrared ray sensor through detecting to detect from the infrared ray of human body radiation.That is whether what, circuit substrate played judgement that whether people is arranged has people's identifying unit.

< position of human body that human body detection device carries out is inferred >

Fig. 5 representes the position of human body critical region that sensor unit 24,26,28 detects, and sensor unit 24,26,28 can detect down respectively whether the people is arranged in the column region.

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

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

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

That is, in the indoor set of air conditioner of the present invention, the zone part that each sensor unit 24,26,28 can detect overlaps, and uses the sensor unit that lacks than the quantity of regional A～G to detect among each regional A～G whether the people is arranged.The output and the relation that people's determinating area (being judged to be people's zone) arranged of each sensor unit 24,26,28 of table 1 expression.Wherein, in table 1 and the following explanation sensor unit 24,26,28 is called first sensor 24, second sensor 26, the 3rd sensor 28.

[table 1]

Fig. 6 is to use first to the 3rd sensor 24,26,28; The flow chart of the region characteristic that is used for after each regional A～G sets, stating; Fig. 7 is to use first to the 3rd sensor 24,26,28; The flow chart that the people is arranged in which zone of determinating area A～G is with reference to the position decision method of these flow charts following explanation people.

At step S1, at first judge with the cycle T 1 (for example 5 seconds) of regulation whether the people is arranged in each zone, and for this decision method, so that whether artificial example is arranged among determinating area A, B, the C, with reference to Fig. 8 explanation.

As shown in Figure 8, cycle T the 1 first to the 3rd sensor 24,26,28 before the time t1 is under the situation of OFF (no pulse), time t1 be judged to be unmanned among regional A, B, the C (A=0, B=0, C=0).Then, the time t2 from time t1 to cycle T after 1, only by first sensor 24 output ON signals (pulse is arranged); At the second and the 3rd sensor 26,28 is under the situation of OFF, is judged to be at time t2, among the regional A people is arranged; Unmanned among area B, the C (A=1, B=0, C=0).And then the time t3 from time t2 to cycle T after 1, first and second sensors, 24,26 output ON signals be under the situation of OFF at the 3rd sensor 28, are judged to be at time t3, and the people is arranged in the area B, among regional A, the C nobody (A=0, B=1, C=0).Below, likewise judge among each regional A, B, the C by each cycle T 1 whether the people is arranged.

Based on this result of determination each regional A～G is differentiated and to be first area (place that the people is often arranged) that the people is often arranged, the short second area of time (just short zone of people's zone, time of staying of passing through etc. through the zone) that the people is arranged, very short the 3rd zone (the non-life that people such as wall, window do not increase basically is regional) of time that the people is arranged.Below; First area, second area, the 3rd zone are called life zoning I, life zoning II, life zoning III respectively, and life zoning I, life zoning II, life zoning III can also be called the zone of region characteristic I, the zone of region characteristic II, the zone of region characteristic III respectively.In addition; Can also life zoning I (region characteristic I), life zoning II (region characteristic II) be closed and be called life zone (zone of people's life); Relative therewith; The zoning of will living III (region characteristic III) is as non-life zone (zone that the people does not live), the regional rough classification that will live according to the frequency whether people is arranged.

Carry out after the step S3 of this differentiation in the flow process of Fig. 6, for this method of discrimination with reference to Fig. 9 and Figure 10 explanation.

Fig. 9 is illustrated in the situation that is provided with the indoor set of air conditioner of the present invention among the LD of the 1LDK that a Japanese bedroom, LD (living room hold concurrently dining room) and kitchen forms, the place through being everlasting of the region representation subject of ellipse representation report among Fig. 9.

As stated, judge among each regional A～G by each cycle T 1 whether the people is arranged,, after the repeated multiple times,, remove all sensor output at step S2 as reaction result (judgement) output 1 (the responding) or 0 (reactionless) of cycle T 1.

In step S3, judge the accumulation duration of runs of the air conditioner that whether has passed through regulation.Do not pass through the stipulated time if in step S3, be judged to be; Then return step S1; On the other hand; Passed through the stipulated time if be judged to be,, differentiated each regional A～G thus and belong among life zoning I～III which respectively then through the reaction result that should accumulate the stipulated time among each regional A～G and two threshold values are compared.

Figure 10 with reference to expression long-term accumulated result further details; Set first threshold and second threshold value littler than first threshold; In step S4, judge whether the long-term accumulated result of each regional A～G is more than first threshold, be judged to be more zone and in step S5, differentiate and be life zoning I.In addition; In step S4, lack than first threshold if judge the long-term accumulated result of each regional A～G, then in step S6; Whether the long-term accumulated result who judges each regional A～G is more than second threshold value; Be judged to be more zone and in step S7, differentiate and be life zoning II, on the other hand, be judged to be still less zone and in step S8, differentiate and be the zoning III that lives.

In the example of Figure 10, zone C, D, G be by the differentiation zoning I alive that makes a living, and area B, F be by the differentiation zoning II alive that makes a living, and regional A, E are by the differentiation zoning III alive that makes a living.

In addition, the LD that Figure 11 is illustrated in other 1LDK is provided with the situation of the indoor set of air conditioner of the present invention, and Figure 12 representes to be based on the result that in this case long-term accumulated result differentiates each regional A～G.In the example of Figure 11, area B, C, E be by the differentiation zoning I alive that makes a living, and regional A, F be by the differentiation zoning II alive that makes a living, and region D, G are by the differentiation zoning III alive that makes a living.

Wherein, the differentiation of above-mentioned zone characteristic (life zoning) in required time repeatedly, the short of sofa that moves the indoor configuration that will differentiate, dining table etc. are differentiated the result and can not changed basically.

Then, with reference to the flow chart of Fig. 7, the final decision whether people is arranged of each regional A～G is described.

Step S1～S2 in the flow chart of step S21～S22 and above-mentioned Fig. 6 is identical, so omit explanation.In step S23, judge the reaction result of the cycle T 1 that whether has obtained stated number M (for example 15 times), do not reach stated number M if be judged to be cycle T 1; Then return step S21; On the other hand, reached stated number M, then in step S24 if be judged to be cycle T 1; The total of the reaction result of cycle T 1 * M as number of times between the accumulation stage of reaction, is calculated number of times between accumulation stage of reaction of 1 time.Calculating to number of times between this accumulation stage of reaction repeats repeatedly, in step S25, judges the result of calculation of number of times between the accumulation stage of reaction that whether has obtained stipulated number (for example N=4); Do not reach stipulated number if be judged to be; Then return step S21, on the other hand, reached stipulated number if be judged to be; Then in step S26, infer among each regional A～G based on number of times between the accumulation stage of reaction of region characteristic of having differentiated and stipulated number whether the people is arranged.

Wherein, in step S27, deduct 1 and return step S21, carry out the calculating of number of times between accumulation stage of reaction of stipulated number thus repeatedly from the calculation times (N) of number of times between the accumulation stage of reaction.

Table 2 expression up-to-date once (historical record of the reaction result of time T 1 * M), in the table 2, for example ∑ A0 is meant among the regional A number of times between accumulation stage of reaction of 1 time.

[table 2]

Here; If number of times is ∑ A1 between 1 time the accumulation stage of reaction before the ∑ A0, number of times is ∑ A2 between 1 time the accumulation stage of reaction before again ..., under the situation of N=4; In past 4 times the historical record (∑ A4, ∑ A3, ∑ A2, ∑ A1); About life zoning I,, just be judged to be the people as long as between the accumulation stage of reaction more than 1 time there be 1 time number of times.In addition, for life zoning II, if in the past in 4 historical records between the accumulation stage of reaction more than 1 time number of times be more than 2 times; Then be judged to be the people; And for life zoning III, if in the past in 4 historical records between the accumulation stage of reaction more than 2 times number of times be more than 3 times, then be judged to be the people.

Then, behind the above-mentioned judgement elapsed time T1 * the M whether people arranged, equally according to past 4 times historical record, life zoning and between the accumulation stage of reaction number of times whether inferring of people is arranged.

Promptly; In the indoor set of air conditioner of the present invention; Infer whether the people is arranged owing to use the sensor that lacks than the quantity of critical region A～G; So in the inferring of each specified period, there is the possibility of misidentification people's position; So avoid overlapping region whether all to carry out people's position deduction with independent estimated period, according to the regional determination of each specified period as a result long-term accumulated region characteristic and the regional determination result of each specified period accumulated the location that the historical record in the past of each regional accumulation reaction times of trying to achieve for N time is inferred the people, obtain the higher people's of probability position deduction result thus.

Table 3 expression judges through such mode whether the people is arranged, be set at T1=5 second, M=12 time situation time that the people infers to be needed is arranged, nobody infers the time of needs.

[table 3]

The life zoning	Someone infers	Nobody infers
			I	60 seconds (soon)	240 seconds (slowly)
II	120 seconds (standard)	180 seconds (standard)
			III	180 seconds (slowly)	120 seconds (soon)

Through such mode; The zone of the indoor set of air conditioner of the present invention being wanted air conditioning is divided into after a plurality of regional A～G with first to the 3rd sensor 24,26,28; Confirm each regional A～G region characteristic (life zoning I～III), so correspondingly change time that the someone infers to be needed with the region characteristic of each regional A～G, nobody infers the time that needs.

Promptly; After change air conditioning setting, wind arrival needs 1 minute degree, so even also can influence comfortableness with short time (for example several seconds) change air conditioning setting; Air conditioning is not preferably carried out from energy-conservation viewpoint in the place that will soon leave for the people in addition.So, detect at first among each regional A～G whether the people is arranged, particularly make the air conditioning in people's zone set optimization.

In detail, with the differentiation be life zoning II the zone whether the someone judges the needed time as standard, in the zone of differentiating for life zoning I; Serving as short time interval of zone of life zoning II to have inferred the people than differentiation; Relative therewith, leave under this regional situation the people, serving as long time interval of zone of life zoning II to infer unmanned than differentiation; Thus will someone infer the time set that needs must be shorter, nobody is inferred the time set that needs must be longer.Otherwise; In the zone of differentiating for life zoning III,, relative therewith to serve as long time interval of zone of life zoning II to have inferred the people than differentiation; Leave under this regional situation the people; Unmanned than differentiation to serve as that short time interval of zone of life zoning II infers, thus will someone infer the time set that needs must be longer, nobody is inferred the time set that needs must be shorter.And then, as stated according to the long-term accumulated result, change each regional life zoning, corresponding with it, the time that the someone is inferred need is variable with the setting that nobody infers the time that needs.

< structure of obstacle detector >

As shown in Figure 1, the bottom in the side (left side of seeing from the front) of main body 2 is provided with obstacle detector 30, describes with reference to Figure 13 for this obstacle detector 30.Wherein, The term of " barrier " that this specification uses; Be meant that obstruction blows out all objects that the air that is used to the occupant and provides comfortable space flows, the for example general name of occupants such as furniture such as desk and sofa, TV, sound equipment object in addition from the blow-off outlet 10 of indoor set.

Obstacle detector 30 comprises: as the ultrasonic type range sensor (following be called separately " ultrasonic sensor ") 32 of distance detecting unit; The spherical supporting mass 34 of ultrasonic sensor 32 is supported in rotation freely; The loudspeaker 36 that on the supporting mass 34 of the sound wave Way out that is positioned at ultrasonic sensor 32, form; Be used to change ultrasonic sensor 32 towards the distance detecting direction change unit (driver element) that makes the change of distance detecting direction.Hyperacoustic sensitivity that loudspeaker 36 are used to ultrasonic sensor 32 is sent improves, and enhancing directive property improves the detection of obstacles precision.

In addition; Supporting mass 34 have level (laterally) rotation with rotating shaft 40 with rotating with rotating shaft 42 with horizontally rotating with the side of rotating shaft 40 quadratures upwardly extending vertical (vertically); Horizontally rotate with rotating shaft 40 and link and driven with horizontally rotating with motor 44, vertical rotation with rotating shaft 42 and vertical rotation with motor 46 bindings also quilt driven.That is, distance detecting direction change unit constitutes with motor 46 etc. by horizontally rotating with motor 44, vertical rotation, can carry out two dimension to the orientation angle of ultrasonic sensor 32 to change, and can discern ultrasonic sensor 32 towards orientation angle.

Then, effect as the ultrasonic sensor 32 of distance detecting unit is described.

The ultrasonic sensor 32 of this embodiment, dual-purpose ultrasonic wave sending part and acceptance division send ultrasonic pulse, reflection when ultrasonic pulse runs into barrier etc., this back wave is received by ultrasonic sensor 32.If this time that is sent to reception is t, when velocity of sound was C, the distance B of ultrasonic sensor 32 to barrier was represented with D=Ct/2.In addition, under the ultrasonic wave sending part and acceptance division condition of different of ultrasonic sensor 32, do not change on principle or the function, in this embodiment, can use yet.

In addition, when establishing ultrasonic sensor 32 and being H, be set to the height of the about 2m of H=usually apart from the height on ground.

And then; With distance detecting direction change unit can with ultrasonic sensor 32 towards direction as the angle (angle of depression of vertical direction; The angle of measuring from the horizontal alignment below) α; The angle of horizontal direction (angle that the datum line from indoor set from the left side (for example, from the front to the left 80 degree) is measured to the right) β identification.When certain side is D=H/sin α upward to the distance B of barrier, can know that this barrier rest on the ground, and can see the ground of this direction with ultrasonic sensor 32 here.

Therefore, the angle [alpha] through making vertical direction and the angle beta of horizontal direction change with the angle intervals of regulation makes ultrasonic sensor 32 detect action (scanning), can discern people and the position of object in the living space.

In this embodiment; With ultrasonic sensor 32 with the ground of living space angle beta based on the angle [alpha] and the horizontal direction of vertical direction; Segmenting as illustrated in fig. 14, is barrier position critical region perhaps " position " with each zone definitions, differentiates which position and has barrier.Wherein, All positions shown in Figure 14 are roughly consistent with the whole zone of position of human body critical region shown in Figure 5; Zone boundary through making Fig. 5 is roughly consistent with the location boundary of Figure 14; Make zone and position correspondence as follows, the air conditioning of stating after can easily carrying out control reduces memory storing as far as possible.

As stated; Air conditioner of the present invention; With among human body detection device surveyed area A～G whether the people being arranged, and with whether having barrier among the A1～G2 of obstacle detector detection position, based on the detection signal (testing result) of human body detection device and the detection signal (testing result) of obstacle detector; Blade up and down 12 and left and right sides blade 14 drive controlling to as wind direction change unit provide comfortable space thus.

Human body detection sensor, for example through detecting from the infrared ray of human body radiation to detect whether the people is arranged, relative therewith, obstacle detector detects the distance of barrier through receiving the hyperacoustic back wave that sends, so can't differentiate people and barrier.

If think the people by mistake barrier, then exist and can't carry out air conditioning the zone that the people is arranged, perhaps air-conditioning wind (air-flow) directly blows to the situation of human body, and the possibility of result can become inefficient air conditioning control or make the people produce the air conditioning control of sense of discomfort.

So for obstacle detector, the data of carrying out following explanation makes it only detect barrier.

The driving method of ultrasonic sensor 32 at first, is described with reference to Figure 15.

Shown in figure 15; In main body 2; Be built-in with three substrates 48,50,52 of mutual electrical connection, be installed on the front surface panel 4 of main body 2, movable part such as blade 12, left and right sides blade 14 is controlled by first substrate 48 up and down, the 3rd substrate 52 is installed with ultrasonic sensor 32 integratedly.

In addition; At second substrate 50; Be provided with sensor input enlarging section 54, frequency domain enlarging section 56, comparison portion 58 and latch cicuit portion 60; Send signal from the ultrasonic wave of first substrate 48 output and be transfused to sensor and be input to enlarging section 54, in sensor input enlarging section 54, carry out voltage amplification after, be imported into the 3rd substrate 52.Ultrasonic sensor 32, based on the signal of being imported, ultrasonic wave is sent in each address of stating backward, receives its back wave and outputs to frequency domain enlarging section 56.Send signal as ultrasonic wave, for example use the signal of 50kHz that repeats 50% dutycycle of ON/OFF with 10 μ s, in frequency domain enlarging section 56, near the signal the 50kHz is amplified.

The output signal of frequency domain enlarging section 56 is imported into comparison portion 58, compares with preset threshold in the comparison portion 58.Comparison portion 58; Signal with L level (low level) under the big situation of the output signal ratio threshold value of frequency domain enlarging section 56 outputs to latch cicuit portion 60; On the other hand, under the little situation of the output signal ratio threshold value of frequency domain enlarging section 56, the signal of H level (high level) is outputed to latch cicuit portion 60.In addition, first substrate 48 will be used to make the reception mask signal of noise separation to output to latch cicuit portion 60.

Wherein, Figure 15 representes that ultrasonic sensor 32 receives one-piece type indoor set for sending, and also can use the transmitter indoor set different with receiver certainly.

Figure 16 representes that (ResetSet: the latch cicuit portion 60 that constitutes of trigger reset-set), table 4 expression is based on the definite output from latch cicuit portion 60 (Q) of two inputs (from the input (RESET input) of comparison portion 58 with from the input (SET input) of first substrate 48) by RS.Expression: H* is under the situation of L level in RESET (resetting) input and SET (set) input in the table 4, is output as the H level, is under the situation of H level in RESET input and SET input, makes output level different because of which becomes the H level earlier.

[table 4]

Mask signal	Comparator output	Latch cicuit output
			SET	RESET	Q
L	L	H*
			L	H	H
H	L	L
			H	H	Constant

In addition, Figure 17 representes the sequential chart of summary of the state of each signal, and is shown in figure 17, during air conditioner running beginning, imports the signal of H level to latch cicuit portion 60 from comparison portion 58.In addition, 54 output ultrasonic waves send signal from the sensor of 48 pairs second substrates 50 of first substrate input enlarging section, and when being transfused to the 3rd substrate 52 from the signal of sensor input enlarging section 54, ultrasonic sensor 32 sends ultrasonic wave to the address of setting.

In addition, ultrasonic wave sends signal just possibly receive the The noise from surrounding environment after the transmission, existing under the situation of influence of noise, is input to comparison portion 58 via frequency domain enlarging section 56.In comparison portion 58, signal of being imported and pre-set threshold are compared, under the situation bigger, the signal of L level is outputed to latch cicuit portion 60 than threshold value.But; The signal that be input to comparison portion 58 this moment is not that ultrasonic sensor 32 receives the signal that generates behind the back wave from the living space; So after the transmission of ultrasonic wave transmission signal, setting the sensor output of regulation covers the time; Cover in the time in sensor output, the reception mask signal of L level is outputed to the latch cicuit portion 60 of second substrate 50 from first substrate 48.

Therefore, the ultrasonic wave that outputs to first substrate 48 from latch cicuit portion 60 receives signal and keeps high level.

On the other hand; The ultrasonic wave that sends from ultrasonic sensor 32 reflects the living space; This back wave (first ripple) is received by ultrasonic sensor 32; Under the signal that is input to comparison portion 58 via frequency domain enlarging section 56 situation bigger than threshold value, the signal with the L level outputs to latch cicuit portion 60 equally.But; Because sensor output is covered time set for shorter than send to the time interval of back wave when receiving from ultrasonic wave; So the reception mask signal of this moment is the H level, be the L level so the ultrasonic wave that outputs to first substrate 48 from latch cicuit portion 60 receives signal.

Ultrasonic wave receives the time that signal is kept the H level; Be meant that ultrasonic sensor 32 sends ultrasonic waves, to the time t that receives till its back wave (first ripple), so as stated; Distance B from ultrasonic sensor 32 to barrier can be through trying to achieve time t and velocity of sound C substitution D=Ct/2.

In addition; When the instrumentation of certain address completion regulation, computing; First substrate 48 sends to the ultrasonic sensor horizontal drive and horizontally rotates with motor driver 62 with signal; Drive horizontally rotating, and the ultrasonic sensor vertical drive is sent to vertical rotation with signal drive with motor 46, therefore change the address of wanting instrumentation with the vertical rotation of 64 pairs of motor drivers with motor 44.

The indicate address of instrumentation of i in the table 5 and j, the angle of vertical direction and the angle of horizontal direction are represented above-mentioned angle of depression α respectively and are seen the angle beta of measuring from the datum line in left side from indoor set to the right.That is, see, on vertical direction 5 degree～80 degree, horizontal direction, set each address, each address of ultrasonic sensor 32 instrumentations, scanning living space in the scope of 10 degree～170 degree from indoor set.

[table 5]

Wherein, whole scannings of the living space that ultrasonic sensor 32 carries out, when the running of air conditioner begins and running stop the time-division and drive row into, the scanning sequency of table 6 expression ultrasonic sensor 32.

[table 6]

That is, when the running of air conditioner begins, from the address [0; 0] to address [32; 0] range determination (position probing of barrier) is carried out in proper order according to this in each address, and then address [0 is arrived in [32,1] in the address; 1] range determination is carried out in proper order according to this in each address, the scanning the when running of end air conditioner begins.

On the other hand, when the running of air conditioner stops, from the address [0; 2] carry out range determination to each address of address [32,2] in proper order according to this, then in the address [32; 3] carry out range determination to each address of address [0,3] in proper order according to this, repeatedly to the address [0; When range determination 15] finishes, the scanning the when running of end air conditioner stops.

Like this, when the running that whole scannings of 32 pairs of living spaces of ultrasonic sensor are divided into air conditioner begins and running carry out when stopping, be in order to carry out the judgement that has or not of barrier expeditiously.That is, when running stopped, movable element such as compressor all stopped; Compare when beginning and be not easy to receive influence of noise with the running of air conditioner; So can be described as the environment that ultrasonic sensor 32 carries out the range determination comparative optimization, but only when the running of air conditioner stops, carrying out whole scannings of living space, ultrasonic sensor 32 not reaction fully when the running beginning; Not only can make the occupant that distrust is arranged, also can increase the sweep time after running stops.

In addition; Scanning limit(s) when the running of air conditioner is begun is in 10 degree of the angle of depression; Be because air conditioner when beginning running has people's possibility higher,, can effectively utilize the instrumentation data (because the people is not a barrier through to the higher zone of the possibility that can not detect the people, promptly have the zone of wall to scan; Of the back, do not use the data in people's zone).

Then, when beginning for the running of air conditioner to the range determination of barrier, with reference to the flowchart text of Figure 18.

At first in step S31, drive horizontally rotating of ultrasonic sensor 32 with motor 44 and the initialization process of vertical rotation with motor 46.Initialization process is meant address [0,0] is set at origin position, and address [16,0] are set at the center, make horizontally rotate with motor 44 and vertical rotation with motor 46 after origin position resets, the control that stops in the center.

In addition, because three substrates 48,50,52 use lead-in wire to connect respectively, so in following step S32; Be used to judge that the self diagnosis that leaded short-term, mistake whether such as connects at unusual ultrasonic sensor 32 handles; If be judged to be no abnormally at step S33, then transfer to step S34, on the other hand; Exist unusually if be judged to be, then finish the range determination flow process.

In step S34, will horizontally rotate with motor 44 and be set in target initial position ([i, j]=[0,0]) with motor 46 with vertical rotation, in next procedure S35, judge whether these motors 44,46 are set in the target location.If be judged to be at step S35 and be set in the target location, then transfer to step S36, on the other hand; Be not set in the target location if be judged to be; Then in step S37, horizontally rotate with motor 44 and handle with the driving of motor 46, return step S35 with vertical rotation.

In step S36, wait for the stipulated time (for example 1 second) in order to make ultrasonic sensor 32 can keep stable state (standing state), in step S38, carry out noise measuring and handle.That is, because ultrasonic sensor 32 receives the influence of sound noise, vibration and electromagnetic noise easily, so after judgement has or not the influence of noise from surrounding environment, transfer to the range determination action.

Handle for this noise measuring, with reference to the flowchart text of Figure 19.

Noise measuring is sent at ultrasonic wave and is carried out (therefore, comparison portion 58 is output as the H level) when signal is the L level, before sending ultrasonic wave transmission signal, the sound wave reception period (for example 100ms) of detection from the regulation of the noise of surrounding environment is set.

In addition; Through before noise measuring; Cover the time (the for example 12ms) of regulation is set, guarantees that the ultrasonic wave when noise measuring begins receives the H level of signal, (for example 4ms) detection noise in required time after the beginning noise measuring after covering effluxion; In comparison portion 58, threshold value and the detected noise that sets compared.And then; In order to prevent misinterpretation; Ultrasonic wave after noise measuring begun during through the stipulated time (for example 100ms) receives signal and reads 2 times; Read for 2 times consistent and be judged to be " not having noise " under the situation of H level (noise is less than threshold value), on the other hand, even a side also is judged to be " noise is arranged " under the situation of L level (noise is more than the threshold value).

Return the flow chart of Figure 18,, carry out whether noisy judgement, do not have noise, then be transferred to step S40, on the other hand,, then be transferred to step S41 if be judged to be noise if be judged to be at next procedure S39.

In step S40, obtain 8 times data in same address, carry out the judgement of whether accomplishing based on the range determination of the data that obtain; Do not accomplish range determination if be judged to be; Then after step S42 sent processing, S43 received processing in step, returned step S40.Otherwise, in step S40, accomplish if be judged to be range determination, then in step S44, carry out distance numbers and confirm to handle.

Wherein, above-mentioned processing is carried out at first substrate 48 and second substrate 50, so first substrate 48 and second substrate 50 play the effect of barrier position detection unit.

In addition; When the distance numbers among the step S44 is confirmed to finish dealing with, judge that in step S45 having carried out distance numbers confirms whether the address of handling is ([i, j]=[0, final address; 1]); Under the situation that is the final address, horizontally rotate with after motor 44 and vertical rotation the initialization process termination routine with motor 46 what step S46 drove ultrasonic sensor 32.Wherein, this initialization process, identical with the initialization process of carrying out at step S31, so omit its explanation.

On the other hand, in step S45, if judge it is not the final address, then at step S47, driving horizontally rotates with motor 44 and makes ultrasonic sensor 32 move to next address with vertical rotation with motor 46, returns step S35.

In addition, in step S39, when being judged to be noise; Because the determination data of current address becomes and can't use; So in step S41, the range data in the past that first substrate 48 is preserved is confirmed as current range data (not upgrading determination data), in step S48; Wait for the stipulated time (for example 0.8s) afterwards, transfer to step S47.

Promptly; Through based on there being noiseless result of determination decision whether to upgrade the result of determination of barrier position detection unit; Can correctly proceed to the range determination of barrier, make air-conditioning wind avoiding obstacles improve air conditioning efficient thereby control wind direction change unit saidly like the back.

Wherein, in step S48, be set the stand-by period, be for the total consumption time that makes each address roughly certain.That is, under noisy situation, do not carry out the processing of step S40, S42, S43, S44, so if the stand-by period is not set, then compares consumption time with the situation that does not have noise and shorten, it is unnatural that the action of ultrasonic sensor 32 can become.In addition, through scanning all barrier position critical regions, and the control obstacle detector makes the total consumption time of each address roughly certain, the occupant produced feel at ease sense.

Then, the distance numbers of the reception processing of the transmission processing of description of step S42, step S43, step S44 is confirmed to handle successively, at first description lanuae " distance numbers ".

" distance numbers " is meant that the approximate distance of certain the position P from ultrasonic sensor 32 to the living space is (of the back; Has certain width); Shown in figure 20; Ultrasonic sensor 32 is arranged on the top apart from ground 2m, establishes from the distance of ultrasonic sensor 32 P to the position during for " ultrasonic wave of the time suitable with distance numbers arrives distance ", and position P representes with following formula.

X=arrives distance * sin (90-α)

Y=2m-arrives distance * sin α

In addition, distance numbers is 2～12 integer value, and the ultrasonic transmission suitable with each distance numbers set two-way time as shown in table 7ly.

[table 7]

Wherein, the position of the position P that table 7 expression is suitable with angle of depression α with each distance numbers, the part Y that has ordinate is negative value (Y＜0), expression is absorbed in the position on ground.In addition, the setting of table 7 is applied to the air conditioner of ability grade 2.2kw, and this air conditioner mainly is arranged on the room (diagonal distance=4.50m), distance numbers=6 are set at limiting value (maximum X) of 6 tatamis.That is, in the room of 6 tatamis, the position suitable with distance numbers >=7 is the position (position in the outside in room) that diagonal distance＞4.50m surpasses room wall, is complete insignificant distance numbers, representes with horizontal line.

And table 8 is the air conditioners that are applied to ability grade 6.3kw, and this air conditioner mainly is arranged on the room (diagonal distance=8.49m), distance numbers=12 are set at limiting value (maximum X) of 20 tatamis.

[table 8]

The limiting value of the distance numbers that the ability grade of table 9 expression and air conditioner and the vertical direction position j of each address correspondingly set.

[table 9]

Then, handle for the transmission processing of step S42 and the reception of step S43, with reference to the sequential chart explanation of Figure 21.

Send signal as ultrasonic wave, as stated, for example the signal with the 50kHz of 50% dutycycle sends with 2ms, sends ultrasonic wave after the 100ms once more and sends signal, carries out so repeatedly, sends the ultrasonic wave that adds up to 8 times in each address and sends signal.Wherein, setting 100ms as measuring interval, is because the time of 100ms is to ignore the time that the influence of the back wave that causes is handled in last transmission.

In addition; Output is covered the time; For example be set at 8ms; Send the reception mask signal of exporting the L level before the 8ms of output of signal at ultrasonic wave, ultrasonic wave receives the H level of signal when guaranteeing to send, and receives mask signal through output till the 8ms and remove noises such as echo signal through sending a signal to from output ultrasonic wave.And then ultrasonic wave receives the input of signal and handles (from the output of latch cicuit portion 60), and is identical with above-mentioned noise measuring processing, and for example every 4ms carries out once.

In addition; Once read repeatedly for the every 4ms of its signal level during transmission that each ultrasonic wave sends signal; In order to prevent that misinterpretation that noise etc. causes from reading unanimity 2 times and under the situation of L level, counting N is deducted 1 value (N-1) as distance numbers (ultrasonic transmission two-way time).In the example of Figure 21; Send ultrasonic wave and send after the signal, the output signal of comparison portion 58 becomes L level (receiving mask signal is the H level) between N=5 and N=6, so ultrasonic wave reception signal o'clock is the H level in N=0～5; At N=6,7 o'clock be the L level; Because when reading unanimity 2 times and being N=7 for the L level, so distance numbers is N-1=6, the time suitable with distance numbers is 6 * 4ms=24ms.

Then, confirm that for the distance numbers among the step S44 processing describes.

As stated; For distance numbers, correspondingly be set with limiting value with the ability grade of air conditioner and the vertical direction position j of each address, receiving signal at ultrasonic wave is under the situation of N＞maximum X; So long as not reading unanimity for 2 times and being the L level, just be set at distance numbers=X.

[i, j] confirms 8 times distance numbers in each address, removes the distance numbers of three maximums and three minimums, gets the mean value of two distance numbers of residue, confirms distance numbers.Wherein, it is integer value that mean value makes the following carry of decimal point, with the suitable ultrasonic transmission two-way time of confirming through such mode of distance numbers, of table 7 or table 8.

Wherein, in this embodiment, confirm eight distance numbers in each address; Remove each three distance numbers of size, get the mean value of two distance numbers of residue, confirm distance numbers; But the distance numbers that each address is confirmed is not limited to eight, and the distance numbers of averaging also is not limited to two.

In addition, when the running of air conditioner stops, carrying out to the range determination of barriers such as furniture, the range determination when running stops for this air conditioner to barrier, with reference to the flow chart of Figure 22 in following explanation.Wherein, the flow chart of Figure 22 and the flow chart of Figure 18 are closely similar, so following the step that explanation is different.

During air conditioner running beginning, in step S34, will horizontally rotate with motor 44 and be set in target initial position ([i with motor 46 with vertical rotation; J]=[0,0]), relative therewith; When the air conditioner running stops, in step S54, will horizontally rotate with motor 44 and be set in target initial position ([i with motor 46 with vertical rotation; J]=[0,2]).

Likewise, when the running of air conditioner begins, in step S45; Judge that having carried out distance numbers confirms whether the address of handling is final address ([i, j]=[0,1]); Relative therewith, when the air conditioner running stops, in step S66; Judge that having carried out distance numbers confirms whether the address of handling is final address ([i, j]=[0,15]).

Range determination when the air conditioner running stops to barrier, the different step S60 that are of maximum during with the running beginning are in step S59; Do not have noise if be judged to be, then in step S60, be judged to be with current address [i; J] in corresponding zone (among the regional A～G shown in Figure 5 some) under the unmanned situation, be transferred to step S61, on the other hand; Be judged to be under people's the situation, be transferred to step S62.Promptly; Because the people is not a barrier; So set for: with the regional corresponding address that is judged to be the people; Do not carry out range determination and be to use range data (not upgrading range data) in the past, only carrying out range determination, use the new range data of measuring (renewal range data) with the regional corresponding address that is judged to be nobody.

Promptly; When in each barrier position critical region, the judgement of clear being arranged; According in the position of human body critical region corresponding whether people's result of determination being arranged with each barrier position critical region; Whether decision upgrades the result of determination of the obstacle detector in each barrier position critical region, and the judgement of clear is arranged thus expeditiously.More specifically; In be judged to be the included barrier position critical region of unmanned position of human body critical region by human body detection device; The result of determination of last time of obstacle detector is upgraded with new result of determination; On the other hand, in the included barrier position critical region of the position of human body critical region that is judged to be the people by human body detection device, the result of determination of last time of obstacle detector is not upgraded with new result of determination.

Wherein, Step 62 in the flow chart of step 41 in the flow chart of Figure 18 or Figure 22; Use range data in the past, but because there is not past data in air conditioner after just having installed, so the judgement in each barrier position critical region that obstacle detector carries out is under the first situation; Use Defaults, use above-mentioned limiting value (maximum X) as default value.

In addition; Can also be shown in figure 23, set the below 2m that ground is positioned at ultrasonic sensor 32, desk, sales counter are positioned at the height apart from ground 0.7～1.2m; Correspondingly set covering the time of acquiescence with scanning position (angle of depression α), the judgement of clear is arranged.Among the figure, lattice portion, upper right oblique line portion, oblique line portion in bottom right representes with closely, during the middle distance, remote suitable detection of obstacles.Wherein, the example of Figure 23 only representes that at angle of depression α is the situation that the scope of 10 degree～65 degree is set the time of covering.

Term " closely ", " middle distance ", " at a distance " of using here; Based on confirming with the distance of indoor set; Shown in figure 23, the position of barrier is based on confirming with the angle of depression α of indoor set with from hyperacoustic transmission time that ultrasonic sensor 32 sends.

More detailed; Correspondingly the time of covering of acquiescence is provided with two shown in table 10 (at a distance), table 11 (middle distance), table 12 (closely) with scanning position; Cover before the time t1 and grow than it cover time t2 after mask signal is outputed to obstacle detector; Only under situation about responding between time t1～t2 (ultrasonic sensor 32 receives the situation of back wave), judge that there is barrier in this position.

In addition; Under barrier and the situation of wall at the same area; Because barrier must be positioned at the position more forward than wall, so under the situation in front of metope is positioned at the position suitable with time t2, t2 revises to default value; And about this modification method, with metope detect in the lump after narrate.

Wherein, In this embodiment; When beginning, the running that is divided into air conditioner for the range determination to barrier carries out when stopping; But in the running of compressor and indoor blower, electrical noise and noise on every side possibly cause harmful effect to ultrasonic sensor 32, so carry out the range determination of the ultrasonic sensor 32 of all addresses also can stop in the running of air conditioner the time.

In addition, setup unit constantly can also be set in the remote controller (long-distance operating device) of operated from a distance air conditioner, the moment of setting at moment setup unit begins the range determination of ultrasonic sensor 32.In this case, be under the situation in the running preferably at the moment air conditioner of setting by moment setup unit, do not begin range determination, under the situation that moment compressor or indoor fan 8 by moment setup unit setting stop, the beginning range determination.

And then; Except the range determination in the above-mentioned moment; For the testing result with ultrasonic sensor 32 is reflected to the running of air conditioner, can also ignore the noise of surrounding environment, when the running of air conditioner begins the range determination of all addresses.

Wherein, in sequential chart shown in Figure 17, be provided with the threshold value that an output signal with frequency domain enlarging section 56 compares, but also can set a plurality of threshold values.

Promptly; Under the situation that a threshold value only is set, when threshold value is low, may reacts to some extent and miss instrumentation echo and ambient noise; When threshold value is higher, may catch the low level signal under barrier situation far away and the environmental condition condition of severe.In addition,, barrier (perhaps metope) carries out the noise inspection before detecting, even but when this inspection, do not detect under the situation of noise, can not guarantee that barrier (perhaps metope) does not have noise when detecting, the ground that possibly when detection of obstacles, happen suddenly produces noise.So; Low threshold value and high threshold are set, will hang down threshold value, high threshold is detected as barrier (perhaps metope) use as noise measuring usefulness; Even burst ground produces under the situation of the noise that surpasses low threshold value during instrumentation, also can reduce the possibility of this noise being thought by mistake reflected signal.The difference of low threshold value and high threshold is big more, and this effect is high more.

Therefore, carry out instrumentation, use high threshold basically in order not react to echo and ambient noise, but when being positioned at barrier (perhaps metope) at a distance and detecting reflected signal a little less than, also possibly return the signal below the high threshold.So,, can improve accuracy of detection through using low threshold value under the situation about detecting at barrier far away (perhaps metope).Wherein, confirm to the distance of the barrier that the detects angle of depression can enough scanning the time.

In addition, can return stronger signal when ultrasonic wave is run into vertical face, but be under the situation on inclined plane at face as object, the big more reflected signal in inclination angle more a little less than, accuracy of detection can descend.So, when metope detects, can improve precision through using low threshold value when the angle of depression big (inclination of=detected object face is bigger).

Under the situation that low threshold value and two threshold values of high threshold are set, insert the flow chart of Figure 24 between step S36 in the flow chart of Figure 18 and the step S38, insert the flow chart of Figure 24 equally between step S56 in the flow chart of Figure 22 and the step S58.

Below, describe for the situation of inserting the flow chart of Figure 24 between step S36 in the flow chart of Figure 18 and the step S38.

At step S37-1; To compare from the noise and the high threshold of surrounding environment,, then make ultrasonic sensor 32 not send ultrasonic wave if noise level is more than the high threshold; Transfer to step S41; If noise level less than high threshold, then in step S37-2, will compare from the noise and the low threshold value of surrounding environment.If noise level is more than the low threshold value, then be judged to be noise, in step S37-3, adopt the threshold value of high threshold as the judgement that is used to have clear, on the other hand, if noise level is then transferred to step S37-4 less than low threshold value.

In step S37-4, judge whether surveyed area is remote zone (area E, F, G), and perhaps whether metope is the inclined plane; At surveyed area is not that remote regional situation or metope are not under the situation on inclined plane; Transferring to step S37-3, on the other hand, is under the situation in remote zone or the situation that metope is the inclined plane at surveyed area; In step S37-5, adopt the threshold value of low threshold value as the judgement that is used to have clear.If a certain side in step S37-3 or step S37-5 in low threshold value or the high threshold is determined, then transfer to step S38, carry out noise measuring and handle.

Wherein, whether metope is the inclined plane, judges (for example, the inclination angle is more than 15 degree) with the angle of metope, particularly, definite based on the angle of the angle of the vertical direction of each address in the table 5 and horizontal direction.

In addition, in the flow chart of Figure 24, set two threshold values, if but set three or the threshold value more than three, then accuracy of detection can further improve.

< Learning Control of detection of obstacles >

Ultrasonic sensor 32; Usually the face angulation of its direction of illumination and object is can correctly measure before and after 90 degree, on the contrary, and along with this angle diminishes; The certainty that back wave returns ultrasonic sensor 32 reduces gradually, and the possibility of detection of obstacles failure uprises.

Consider that the smooth desks such as dining table of upper surface are as an example; Under the situation that does not have object on the desk; The possibility of after the upper surface reflection of desk, returning ultrasonic sensor 32 from the transmission ripple of ultrasonic sensor 32 is extremely low; The position that is difficult to carry out desk confirms, and is relative therewith, when having daily necessities (tableware, remote controller, book, newspaper, paper towel box etc.) on the desk; Transmission ripple from ultrasonic sensor 32 can return ultrasonic sensor 32 (for example with reference to Figure 29) after the reflection on desk and the daily necessities, carries out the position of desk easily and confirms.

So, in this Learning Control, for detection of obstacles, except barrier, also utilize and be positioned near the barrier around the interaction of spin off carry out.But; It is actual that to be placed on the possibility that (in fact being furniture not equal to be the daily necessities of placing on the furniture) every days such as furniture in the room, its place changed higher; The interaction of spin off can change around near the angle of barrier and the barrier; So, can reduce faults as far as possible through carrying out detection of obstacles repeatedly.This Learning Control shown in the flow chart that Figure 25 representes, based on scanning result learning disorder object location each time, is judged the place that has barrier according to this Learning Control result, the air-flow of stating after carrying out control.

Figure 25 representes to have the flow chart of the judgement of clear, and this has the judgement of clear, carries out successively for all positions shown in Figure 14 (barrier position critical region).Here, be the example explanation with position A1.

During with ultrasonic sensor 32 beginning detection of obstacles actions; At first in step S71; Action (scanning) is detected with ultrasonic sensor 32 in the initial address of A1 in the position, in step S72, carries out the above-mentioned judgement (time t1～t2 has unresponsive judgement) that clear is arranged.At step S72, there is barrier if be judged to be, then in step S73, the first memory that is arranged on the 3rd substrate 52 is added " 1 ", on the other hand, there is not barrier if be judged to be, then in step S74, first memory is added " 0 ".

In step S75, judge whether the detection of the final address of position A1 finishes, under the unclosed situation of the detection of final address,, detect action with ultrasonic sensor 32 at next address at step S76, return step S72.

On the other hand; Under the situation that the detection of final address has finished, at step S77, with the number of addresses (carry out division arithmetic) of numerical values recorded in the first memory (being judged to be the total of the address that has barrier) divided by position A1; And, its merchant is compared with threshold value at next procedure S78.Under merchant's situation bigger than threshold value, at step S79, temporarily be judged to be position A1 and have barrier, in step S80, second memory is added " 5 ".On the other hand, under the situation of merchant less than threshold value, in step S81, temporarily being judged to be position A1 does not have barrier, in step S82, second memory is added " 1 " (deducting " 1 ").

Wherein, the distance from ultrasonic sensor 32 to barrier is far away more, and the detection of obstacles of being undertaken by ultrasonic sensor 32 is more difficult, thus the threshold value of here using, according to the distance of indoor set, for example set as follows.

Closely: 0.4

Middle distance: 0.3

At a distance: 0.2

In addition, this detection of obstacles action is carried out when making the air conditioner running, so in second memory, add " 5 " perhaps " 1 " repeatedly at every turn.So numerical values recorded in the second memory is set at " 10 " with maximum, minimum of a value is set at " 0 ".

Then, at step S83, judge in the second memory that whether numerical values recorded (total after the add operation) is more than the determinating reference value (for example 5); If more than the determinating reference value, then in step S84, there is barrier in final decision position A1; On the other hand; If less than the determinating reference value, then at step S85, final decision position A1 clear.

Wherein, first memory is when the detection of obstacles release of some positions; Can pass through its memory clear-up; As the memory of the detection of obstacles of next position action, and second memory, the value added that can accumulate a position when at every turn making the air conditioner running (wherein; Maximum >=total >=minimum of a value), so the memory of preparation and number of positions equal number.

In the Learning Control of above-mentioned detection of obstacles, set " 5 " as the determinating reference value, when there is barrier in final decision in the first detection of obstacles of some positions, record " 5 " in second memory.Under this state, if final decision clear in the detection of obstacles next time, the value that then " 5 " is added " 1 " is less than the determinating reference value, so this position clear.

But; If finally still judge in the detection of obstacles to have barrier next time, then in second memory, write down the value " 10 " that " 5 " is added " 5 ", aggregate value is more than the determinating reference value; So there is barrier in this position; Even judge clear 5 detection of obstacles, because " 10 " add that the value of " 1 * 5 " is for " 5 ", so still there is barrier in this position from next time.

Promptly; The Learning Control of this detection of obstacles is characterised in that; Based on repeatedly increase aggregate-value (perhaps adding and subtracting aggregate-value) when the final decision of clear is arranged,, be set at the enough big numeral of value that deducts when being judged to be clear with being judged to be the value that adds when having barrier; Through such setting, draw the result who has barrier easily.

In addition, through numerical values recorded in the second memory is set maximum and minimum of a value, even, also can follow the trail of its variation as soon as possible because of removal of home or finishing etc. changes the position of barrier significantly.Be not provided with under the peaked situation; When there was barrier in each judgement, itself and increase were gradually waiting the change in location that makes barrier because of removal of home; Be judged to be under the situation that no longer has barrier in the zone that has barrier at every turn, make it to drop to below the determinating reference value and also can expend time in.In addition, under the situation that minimum of a value is not set, the phenomenon opposite with it can take place.

Figure 26 representes the variation of the Learning Control of the detection of obstacles shown in the flow chart of Figure 25, and only the processing of step S100, S102, S103 is different with the flow chart of Figure 25, so these steps are described.

In this Learning Control,, there is barrier, then in step S100, second memory added " 1 " if temporarily judge position A1 at step S99.On the other hand, at step S101,, then in step S102, second memory is added " 0 " if temporarily judge position A1 clear.

Then, at step S103, will record aggregate value and determinating reference value in the second memory (for example 2) based on the past that comprises current detection of obstacles 10 detection of obstacles and compare; If be more than the determinating reference value, then at step S104, there is barrier in final decision position A1; On the other hand; If less than the determinating reference value, then in step S105, final decision position A1 clear.

That is, the Learning Control of above-mentioned detection of obstacles, even fail to detect barrier 8 times in the past of some positions 10 times the detection of obstacles, as long as 2 times can detect barrier, then there is barrier in final decision.Therefore; This Learning Control is characterised in that, there is the detection of obstacles number of times (being 2) of barrier here in final decision, is set at than the abundant little numeral of the detection of obstacles number of times in past of reference; Through setting in this wise, draw the result who has barrier easily.

In addition, also can on indoor set main body or remote controller, be provided with and make the button that data recorded is reset in the second memory,, above-mentioned data are reset through pressing this button.

Basically; The barrier that control affects greatly to air-flow and the less change in position of metope; But take place to cause along with the change of the desired location of the indoor set of removal of home with because of the finishing in the room under the situation of change etc. of furniture position, the data that obtain before not being preferably based on are not carried out air-flow control.This is because through Learning Control, can become the control that is fit to this room, but to becoming Optimal Control need expend time in (it is significant no longer existing under the situation of barrier in particularly should the zone).Therefore; The replacement button is set; Under the situation that the relative position of indoor set and barrier or metope relation changes,, can prevent unsuitable air conditioning based on the data of the mistake in past through data replacement that will be so far; And, can realize cooperating quickly the control of this situation through from restarting Learning Control at first.

<barrier is hidden control >

Based on the above-mentioned judgement that whether has barrier,, when heating, control as follows as the blade up and down 12 and left and right sides blade 14 of wind direction change unit.

Below in the explanation, use term " piecemeal (block) ", " subregion (filed) ", these terms at first are described.

Regional A～G shown in Figure 5 belongs to following piecemeal respectively.

Piecemeal N: regional A

Piecemeal R: area B, E

Piecemeal C: zone C, F

Piecemeal L: region D, G

In addition, regional A～G belongs to following subregion respectively.

Subregion 1: regional A

Subregion 2: area B, D

Subregion 3: zone C

Subregion 4: area E, G

Subregion 5: regional F

And then, define as follows for distance with indoor set.

Closely: regional A

Middle distance: area B, C, D

At a distance: area E, F, G

The goal-setting angle of 5 pieces of lobus sinister sheets of table 13 expression formation left and right sides blade 14 and each position of 5 pieces of lobus dexter sheets; To numeral (angle) additional symbol; Shown in figure 27; Lobus sinister sheet or the situation of lobus dexter sheet towards the inboard just are being defined as the direction of (+, in the table 13 for no symbol), situation toward the outer side are being defined as the direction of negative (-).

[table 13]

In addition, " heating B zone " in the table 13 is meant and carries out the heating area that barrier is hidden control, and " wind direction control automatically usually " is meant and does not carry out the wind direction control that barrier is hidden control.Here; Whether carry out the judgement that barrier is hidden control; Temperature with indoor heat converter 6 is a benchmark; Under the lower situation of temperature, make wind can not blow to occupant's wind direction control, under too high situation, carry out the wind direction control of maximum quantity of wind position, under the situation of suitable temperature, carry out wind direction control to heating B zone.In addition, said here " temperature is lower ", " too high ", " making wind can not blow to occupant's wind direction control ", " the wind direction control of maximum quantity of wind position " are the implications that is described below.

Lower temperature: the temperature of indoor heat converter 6 is set at optimum temperature with skin temperature (33～34 ℃), possibly become the temperature (for example 32 ℃) below this temperature

Too high temperature: for example more than 56 ℃

Make wind can not blow to occupant's wind direction control: for to the living space air-supply, blade 12 up and down to be carried out angle control, the wind direction control that wind is flowed along the roof

The wind direction control of maximum quantity of wind position: air conditioner; Cause certainly leads to resistance (loss) when blade 12 makes air-flow crooked with left and right sides blade 14 up and down; The maximum quantity of wind position is meant to lose infinitely controls (situation of left and right sides blade 14 is as the crow flies towards the position in front, and the situation of blade 12 is the position from downward 35 degree of level up and down) near 0 wind direction

Table 14 expression is carried out barrier and is hidden the goal-setting angle in each subregion of blade up and down 12 of situation of control.Wherein, the angle (γ 2) of angle of the blade in the table 14 (γ 1) and lower blade is the downward angle of measuring from horizontal line (angle of depression).

[table 14]

Then, specify, explain at first that barrier hides that the term that uses in the control " shakes (swing) action ", " position stops running " for hiding control with the corresponding barrier in the position of barrier.

Shaking action and be meant the action of shaking of left and right sides blade 14, is that a position with target is that the center is shaken with the left and right sides angle amplitude of regulation basically, and the two ends of shaking do not have the action of set time.

In addition, the position stops running and is meant the goal-setting angle (angle of table 13) for some positions, carries out the correction of table 15, is made as left end and right-hand member respectively.As action, have respectively the wind direction set time (the fixedly time of left and right sides blade 14) at left end and right-hand member, for example;, move through under the situation of wind direction set time at left end, till the right-hand member process wind direction set time to right-hand member; Keep the wind direction of right-hand member; After wind direction set time warp, move to left end, it is carried out repeatedly.The wind direction set time for example is set at 60 seconds.

[table 15]

That is, exist in some positions under the situation of barrier, when directly using the goal-setting angle of this position, warm braw can directly blow to barrier, and through carrying out the correction of table 15, can make warm braw arrive the position that the people is arranged from the next door of barrier.

And then piecemeal stops running and for example is meant and confirms based on table 16, the set angle of the left and right sides blade 14 corresponding with the left end of each piecemeal and right-hand member.As action, has the wind direction set time respectively at the left end and the right-hand member of each piecemeal, for example;, move through under the situation of wind direction set time at left end, till the right-hand member process wind direction set time to right-hand member; Keep the wind direction of right-hand member; After the wind direction set time warp, move, it is carried out repeatedly to left end.The wind direction set time, identical with position stop running, for example be set at 60 seconds.Wherein, owing to the left end and the right-hand member of the included position of human body critical region of left end and right-hand member and this piecemeal of each piecemeal are consistent, piecemeal stops the stop running that running also can be described as the position of human body critical region.

[table 16]

Wherein, the position stops running and piecemeal stops running, correspondingly uses respectively with the size of barrier.Under the less situation of barrier forwardly; Through being that the center is carried out the position and stopped running and come the avoiding obstacles air-supply with the position that has barrier; Relative therewith; Barrier forwardly is bigger, for example has under people's the situation of the place ahead global existence barrier in zone, through carrying out that piecemeal stops running and in wider scope air-supply.

In this embodiment, stop the action of shaking that running is referred to as left and right sides blade 14 with shaking action, position stop running and piecemeal.

Below; The control of blade 12 or left and right sides blade 14 example about specifying; And judge the situation that the people is only arranged in single area at human body detection device; Be judged to be by obstacle detector that critical region exists under the situation of barrier in the barrier position in the place ahead that is arranged in the position of human body critical region that is judged to be the people by human body detection device, the air-flow control of the avoiding obstacles from the top is carried out in control blade 12 up and down.In addition; Exist under the situation of barrier being judged to be by obstacle detector in the included barrier position critical region of the position of human body critical region that is judged to be the people by human body detection device; Select a kind of in controlling of first air-flow control and second air-flow; This first air-flow control; In at least one included barrier position critical region of the position of human body critical region that is judged to be the people, left and right sides blade 14 is shaken, the set time of left and right sides blade 14 is not set at the two ends of swing range; This second air-flow control; Perhaps with at least one included barrier position critical region of the position of human body critical region of this zone adjacency left and right sides blade 14 is shaken at the position of human body critical region that is judged to be the people, the set time of left and right sides blade 14 is set at the two ends of swing range.

In addition, in the following explanation, the up and down control of blade 12 and the control of left and right sides blade 14 are separated, but also can be according to the position of people and barrier, the control appropriate combination of the control of blade 12 and left and right sides blade 14 is carried out up and down.

A. blade control up and down

(1) some among area B～G has the people, has the position A1～A3 in the place ahead in people's zone to have the situation of barrier

The set angle of blade 12 is up and down revised with respect to common subregion wind direction control (table 14) shown in table 17ly, carried out blade 12 up and down is set at air-flow control upwards.

[table 17]

(2) some among area B～G has the people, and the situation (above-mentioned (1) in addition) of clear among people's the regional A in the place ahead in zone is arranged

Carry out wind direction control automatically usually.

B. left and right sides blade control

B1. regional A has (closely) people's situation

(1) position of clear is one a situation among the regional A

With the goal-setting angle of the position of clear be about the center shake action, carry out the control of first air-flow.For example; There are barrier in A1, A3 in the position, under the situation of position A2 clear, with the goal-setting angle of position A2 be about the center shake action; Basically the position A2 to clear carries out air conditioning; And not necessarily unmanned because of position A1, A3, so shake action, make distribution of air flow give position A1, A3 a little through additional.

More specifically; Based on table 13 and table 15; Confirmed goal-setting angle and the angle correction (shaking the angle of shaking when moving) of position A2,, in the angular range of ± 10 degree, do not continued to shake (swing) respectively with stopping so lobus sinister sheet and lobus dexter sheet are the center with 10 degree all.But the moment that lobus sinister sheet and lobus dexter sheet are swung to the left and right is set at identical, lobus sinister sheet and lobus dexter sheet shake the action interlock.

(2) position of clear is the situation (A1 and A2 or A2 and A3) of two and adjacency among the regional A

Goal-setting angle with two positions of clear is shaken action as two ends, carries out the control of first air-flow, thus basically to the position air conditioning of clear.

(3) position of clear is two and the situation (A1 and A3) of separating among the regional A

Carry out piecemeal with the goal-setting angle of two positions of clear as two ends and stop running, carry out the control of second air-flow.

(4) all there is the situation of barrier in all positions among the regional A

Because where to be that target is better indeterminate, institute stops running so that piecemeal N carries out piecemeal, carries out the control of second air-flow.This be because, and be that target is compared with the regional integration, piecemeal stops the wind direction that the mode of running has directive property, arrives easily at a distance, possibility that can avoid-obstacles is high.That is,, common gap is arranged also between barrier and barrier, can blow through the gap between this barrier even be scattered with under the situation of barrier at regional A.

(5) situation of all equal clears in position among the regional A

Carry out the wind direction control automatically usually of regional A.

B2. some situation that the people is arranged among area B, C, the D (middle distance)

(1) there is in two positions that people's zone comprises a side only have the situation of barrier

With the goal-setting angle of the position of clear as the center about ground shake action, carry out the control of first air-flow.For example, the people being arranged in region D, only exist under the situation of barrier at position D2, is that ground shakes action about the center with the goal-setting angle of position D1.

(2) all there is the situation of barrier in two position both sides that have people's zone to comprise

Make the piecemeal in the zone that includes the people carry out piecemeal stop running, carry out the control of second air-flow.For example, the people is arranged and all have under the situation of barrier, make piecemeal L carry out piecemeal and stop running position D1, D2 both sides in region D.

(3) situation of clear in people's the zone is arranged

Usually the wind direction control automatically in someone zone.

B3. some situation that the people is arranged among area E, F, the G (at a distance)

(1) there is in two included positions of people's the middle distance zone in the place ahead in zone a side only have the situation (for example: the people is arranged in the area E, have barrier among the B2 of position, position B1 clear) of barrier

(1.1) there is the situation (for example: position B1, C1 clear) of both sides clear of the position of barrier

(1.1.1) exist barrier the position the rear clear situation (for example: position E2 clear)

Carry out the position with the position that has barrier as the center and stop running, carry out the control of second air-flow.For example, the people is arranged in area E, there is barrier in position B2, and under the situation of the equal clear in its both sides and rear, the barrier that can avoid from the side among the B2 of position is sent into air-flow to area E.

(1.1.2) exist the rear of the position of barrier that the situation (for example: have barrier among the E2 of position) of barrier is arranged

Goal-setting angle in the middle distance zone with the position of clear is shaken action as the center, carries out the control of first air-flow.For example, the people is arranged in area E, there is barrier in position B2, and its both sides do not have barrier, and the rear exists under the situation of barrier, and it is more favourable to send into air-flow from the B1 of clear.

(1.2) have that there is barrier in a side, the situation of the opposing party's clear in the both sides of position of barrier

Goal-setting angle with the position of clear is shaken action as the center, carries out the control of first air-flow.For example, in regional F, the people is arranged, there is barrier in position C2, and there is barrier in position D1 in the both sides of position C2, under the situation of clear, can avoid the barrier of position C2 from the C1 of clear air-flow is delivered to regional F among the C1.

(2) there are two included position both sides of middle distance zone in the place ahead in people's zone all to have the situation of barrier

Make the piecemeal in the zone that includes the people carry out piecemeal stop running, carry out the control of second air-flow.For example, the people is arranged and all have under the situation of barrier, make piecemeal C carry out piecemeal and stop running position C1, C2 both sides at regional F.In this case, owing to barrier is arranged, and can't avoiding obstacles, so, all carry out piecemeal and stop running no matter whether barrier is arranged with the piecemeal of piecemeal C adjacency in the place ahead of people.

(3) situation (for example: among the regional F people is arranged, position C1, C2 clear) of two included equal clears of position both sides of people's the middle distance zone in the place ahead in zone is arranged

(3.1) situation that has barrier in a side the position is only arranged in two regional included positions of people

Goal-setting angle with the opposing party's of clear position is shaken action as the center, carries out the control of first air-flow.For example, in regional F, the people is arranged, position C1, C2, F1 clear; Exist among the F2 of position under the situation of barrier; Open in the place ahead of someone regional F, so consider remote barrier, carries out air conditioning with the remote position F1 of clear as the center.

(3.2) there are two regional included position both sides of people to have the situation of barrier

Make the piecemeal in the zone that includes the people carry out piecemeal stop running, carry out the control of second air-flow.For example; The people is arranged and do not have barrier and all have under the situation of barrier at regional G,, barrier is arranged at this regional integration though there is the place ahead of regional G of people open position G1, G2 both sides at position D1, D2; Where to be that target is better indeterminate, institute stops running so that piecemeal L carries out piecemeal.

(3.3) situation of two regional included equal clears of position both sides of people is arranged

Usually the wind direction control automatically in someone zone.

Wherein, This barrier is hidden control; The whether someone who carries out based on human body detection device judges that the clear that has of carrying out with obstacle detector judges; Control is blade 12 and left and right sides blade 14 up and down, but having or not of the barrier that also can be only carries out based on obstacle detector judged and controlled blade 12 and left and right sides blade 14 up and down.

< only hiding control>based on the barrier that has or not judgement of barrier

This barrier is hidden control, is basically to be judged to be the zone that has barrier in order to avoid by obstacle detector, and orientation judging is to blow in the zone of clear, below its concrete example of explanation.

A. blade control up and down

(1) there is (closely) situation of barrier in regional A

To lighten the heating installation that floats in order suppressing to heat and to make up and down blade 12 when the below is seen warm braw off; In regional A, exist under the situation of barrier; Consider that heating installation accumulates in the back side (indoor set one side) of barrier, perhaps heating installation runs into barrier and can not arrive the problem on ground.

So; The set angle of blade 12 lifts 5 degree with respect to common subregion wind direction control (table 14) with blade 12a about detecting under the situation of barrier under the indoor set or near it, making; Lower blade 12b lifts 10 degree; Make angle of depression α be respectively 70 degree and 55 degree, carry out that blade 12 up and down is set at air-flow upwards and control, carry out air conditioning from the top of barrier.Air-flow integral body is upwards lifted when too much, and heating installation can directly be run into occupant's face, makes it produce sense of discomfort, so with lower blade 12b heating installation is lifted, avoiding obstacles prevents to float with blade 12a.

B. left and right sides blade control

(1) the some situation that has barrier among area B, C, the D (middle distance)

Carry out air conditioning for clear emphasis ground.For example; Detect the situation of barrier in zone C (room central authorities); Area B through making the both sides that comprise clear, the piecemeal of D alternately carry out piecemeal and stop running, can carry out air conditioning to the regional emphasis ground of clear (=have people's possibility higher).

In addition, the situation in that area B or D (corner in room) detect barrier makes the piecemeal that comprises zone C and D or area B and C carry out piecemeal and stops running.In this case; Repeatedly in (for example 5 times) 1 time ratio to be arranged; Making zone C and D or area B and C carry out piecemeal stops after the running; Making left and right sides blade 14 when area B or D shake, not only can higher zone be that air conditioning is carried out at the center with the possibility that the people is arranged, and on whole this aspect of air conditioning in room, also is effective.

In addition; Differentiate the position that has or not (barrier position critical region) of barrier; Also can irrespectively segment as illustrated in fig. 14 with the ability grade of air conditioner; And because the size in the room that correspondingly is provided with ability grade is also different, so also can change cut zone quantity.For example, ability grade is 4.0kw when above, cuts apart as illustrated in fig. 14, is 3.6kw when following, also remote zone can be set, and nearby region is divided into three parts, is six parts with the middle distance Region Segmentation.

And then, shown in figure 14, discerning the room radially, from indoor set equally spaced be divided into closely// at a distance under the situation, more away from indoor set, its area is big more.So, through making critical region quantity many more away from indoor set more, can make each regional size roughly even, be easy to carry out air-flow control.

In addition, whole scannings of living space are carried out through making ultrasonic sensor 32 send ultrasonic wave to each address shown in the table 5, but also can correspondingly be increased the angle intervals when scanning with the distance from the indoor set to the critical region.

Here, detected cells territory that will be corresponding with each address is during with " unit (cell) " this term performance, and each regional detecting unit quantity increases more, and accuracy of detection can improve, but can increase sweep time, so preferably consider and take into account accuracy of detection and sweep time.So; For example; Through (angle of depression α: 25 degree～65 degree) horizontal direction and vertical direction are all scanned by 10 degree in in-plant each address of correspondence; And at each address of corresponding middle distance (angle of depression α: 15 degree～30 are spent) and corresponding each address at a distance (angle of depression α: 10 degree～20 degree) horizontal direction and vertical direction are all spent scanning by 5, can make each regional detecting unit quantity (general about 20) about equally.

< people's wall is near control >

Under human body and the situation of wall at the same area, the people must be positioned at than the forward position of wall near wall, during heating; Warm braw is trapped near the wall easily; Have near the room temperature of wall to compare higher tendency with the room temperature of other parts, during cooling, cold wind is easy to be trapped near the wall; Near the room temperature tendency lower than the room temperature of other parts of wall arranged, so carry out people's wall near control.

In this control; Send ultrasonic wave by ultrasonic sensor 32 to the front in the front that is positioned at indoor set wall and the left and right sides wall (indoor set is provided with the surrounding wall in space) that is positioned at the both sides of front wall; Detect its back wave, at first the positive wall of identification with about the position of wall.

That is, drive ultrasonic sensor 32, at first send ultrasonic wave to the left side of general horizontal direction; Detect the distance that is measured to the left side wall behind its back wave; Try to achieve distance numbers, then send ultrasonic wave, detect the distance that is measured to the front wall behind its back wave to the front of general horizontal direction; Try to achieve distance numbers, try to achieve the distance numbers of right side wall at last equally.

And then, be described in detail with reference to Figure 28.Figure 28 is the figure that sees the room that indoor set has been installed from the top, and there is the situation of front wall WC, left wall WL, right side wall WR respectively in expression from front, left side and right side that indoor set is seen.Wherein, the distance numbers of the lattice number that the numeral in Figure 28 left side is corresponding, table 18 is represented from indoor set to the perigee corresponding with distance numbers and apogean distance.

[table 18]

Distance numbers	Perigee (m)	Apogee (m)

As stated; " barrier " that uses in this specification is envisioned for for example furniture such as desk and sofa, TV, sound equipment etc., considers the common height of these barriers, in the angular range of the angle of depression 15 degree, can not detect; Can presumptive detection to be wall; So in this embodiment, 15 degree are with the distance of interior detection indoor set to positive, left end and right-hand member at the angle of depression, there is wall comprising on the extended line of this position.

In addition; In the angle of visibility of horizontal direction; Can infer left side wall WL and be positioned at the position that angle 10 degree, 15 are spent, front wall WC is positioned at the position of angle 75 degree～105 degree, and right side wall WR is positioned at the position of angle 165 degree, 170 degree; So in the address shown in the table 5, corresponding address is as follows respectively in the angle of depression 15 is spent with the angle of visibility of interior and above-mentioned horizontal direction.

Left end: [0,0], [1,0], [0,1], [1,1], [0,2], [1,2]

Positive: [13,0]～[19,0], [13,1]～[19,1], [13,2]～[19,2]

Right-hand member: [31,0], [32,0], [31,1], [32,1], [31,2], [32,2]

When confirming the distance numbers from indoor set wall WL, front wall WC, right side wall WR to the left side, shown in table 19, at first in above-mentioned each address extraction metope data.

[table 19]

Then, shown in table 20, delete the higher limit and the lower limit of each metope data, get rid of unnecessary metope data, be determined to the distance numbers of front wall WC, left side wall WL, right side wall WR based on the metope data of such acquisition.

[table 20]

Can adopt the distance numbers of maximum (WL:6, WC:5, WR:3) conduct wall WL, front wall WC, right side wall WR in the table 20 to the left side.Adopting under the peaked situation,, can set the object of wider space as air conditioning control to carrying out air conditioning from the distance of indoor set wall WL, front wall WC, right side wall WR room (bigger room) far away to the left side.But, not necessarily to be maximum, also can adopt mean value.

Be determined to through such mode after the distance numbers of left side wall WL, front wall WC, right side wall WR; Judge by human body detection device to be judged to be in the included barrier position critical region of people's position of human body critical region whether have wall with obstacle detector; There is wall if be judged to be; Consider that then there is the people in wall the place ahead, so when heating, the lower slightly temperature of design temperature of carrying out setting than remote controller is set; When cooling, the slightly high temperature of design temperature of carrying out setting than remote controller is set.

Below, be that example specifies when controlling with heating to this people's wall is approaching.

A. the people is positioned at the situation in nearby region or middle distance zone

Because nearby region and middle distance zone are positioned at the position nearer apart from indoor set, region area is also less, so the degree that room temperature rises is higher, so the design temperature that remote controller is set is set at reduction by first set point of temperature (for example 2 ℃).

B. the people is positioned at the situation in remote zone

Because remote zone is positioned at the position far away apart from indoor set; Region area is also bigger; So the degree that room temperature rises is lower than nearby region or middle distance zone, so the design temperature that remote controller is set is set at second set point of temperature (for example 1 ℃) that reduction is lacked than first set point of temperature.

In addition; The region area in remote zone is bigger; Even have people and wall so in same position of human body critical region, detect, also have people and wall away from possibility, so only under the situation of the combination shown in the table 21; Carry out people's wall near control, correspondingly carry out temperature inversion (shift) with the position relation of people and wall.

[table 21]

< covering the correction of time T 2 >

Wherein, when confirming the position of barrier, preceding text have been narrated the time of covering t1, the t2 that sets acquiescence, and the correction of the time of the covering t2 that carries out after the distance numbers for wall WL, front wall WC, right side wall WR on the left of being determined to, in following explanation.

Table 22 expression and the angle (β) of horizontal direction and the corresponding time of the covering t2 of distance numbers of front wall WC; Table 23 expression and the angle (β) of horizontal direction and the corresponding time of the covering t2 of distance numbers of left side wall WL, table 24 expression and the angle (β) of horizontal direction and the corresponding time of the covering t2 of distance numbers of right side wall WR.

[table 22]

[table 23]

[table 24]

The time of covering t2 shown in table 22～24; Correction value as default value t2; The distance numbers that is provided with the wall of indoor set is WL=5, WC=9, WR=4; Under the remote situation that detects the angle of depression 10 degree, the default value of time t2 is 44, so use the numerical value conduct of the circle symbol of the table 25 littler than this default value to cover time t2.

[table 25]

In addition, be under the situation of t2＜t1 at revised like this time t2, judge clear in this address.

Through such correction default value t2, can wall be identified as barrier, hide control so can carry out above-mentioned barrier effectively.

< separation detection of wall and barrier >

In addition, because of wall and barrier, the angle of depression when ultrasonic sensor 32 detects is different; So; Through being controlled to when wall detects and during detection of obstacles, making ultrasonic sensor 32 carry out different actions, can efficient well and correctly detect wall and barrier.

Enumerate an example, when wall detects, carry out range determination according to following order.

Address [0,0] → address [32,0] → address [32,1] → address [0,1] → address [0,2] → address [32,2] → wall detects and finishes

On the other hand, when detection of obstacles, in the scope that is equivalent to the remote angle of depression 10 degree～20 degree, horizontal direction and vertical direction are all carried out range determination with 5 degree according to following order.

Address [0,1] → address [9,1] → address [9,2] → address [0,2] → address [0,3] → address [9,3] → first time, remote instrumentation finished

Address [10,1] → address [21,1] → address [21,2] → address [10,2] → address [10,3] → address [21,3] → second time, remote instrumentation finished

Address [22,1] → address [32,1] → address [32,2] → address [22,2] → address [22,3] → address [32,3] → last remote instrumentation finishes

In addition, in the scope of the angle of depression that is equivalent to middle distance 15 degree～30 degree, horizontal direction and vertical direction are all carried out range determination with 5 degree according to following order.

Address [0,2] → address [9,2] → address [9,3] → address [0,3] → address [0,4] → address [9,4] → address [9,5] → address [0, the 5] → middle distance instrumentation end first time

Address [10,2] → address [21,2] → address [21,3] → address [10,3] → address [10,4] → address [21,4] → address [21,5] → address [10, the 5] → middle distance instrumentation end second time

Address [22,2] → address [32,2] → address [32,3] → address [22,3] → address [22,4] → address [32,4] → address [32,5] → address [22,5] → last middle distance instrumentation finishes

And then, in the scope that is equivalent to the in-plant angle of depression 25 degree～65 degree, horizontal direction and vertical direction are all carried out range determination with 10 degree according to following order.

Address [0,4] → address [9,4] → address [9,6] → address [0,6] → address [0,8] → address [9,8] → address [9,10] → address [0,10] → address [0,12] → address [9,12] → first time, closely instrumentation finished

Address [10,4] → address [21,4] → address [21,6] → address [10,6] → address [10,8] → address [21,8] → address [21,10] → address [10,10] → address [10,12] → address [21,12] → second time, closely instrumentation finished

Address [22,4] → address [32,4] → address [32,6] → address [22,6] → address [22,8] → address [32,8] → address [32,10] → address [22,10] → address [22,12] → address [32,12] → last closely instrumentation finishes

Promptly; In corresponding to remote each address (angle of depression α=10 degree～20 degree) and each address (angle of depression α: 15 degree～30 are spent) corresponding to middle distance; Scan in vertical direction and upward per 5 degree of horizontal direction (left and right directions); On the other hand, in corresponding to in-plant each address (angle of depression α: 25 degree～65 are spent), per 10 degree scan on vertical direction and horizontal direction.This is the characteristic for the surveyed area that produces ultrasonic sensor shown in Figure 29 32; Shown in figure 30, the angle of depression more little (more near level), far away more to the distance of barrier; So the surveyed area of ultrasonic sensor 32 is more little; Consequently, need reduce differential seat angle (below, abbreviate " driving angle " as) between each address.Otherwise but under the situation of the angle of depression big (near vertical), surveyed area broadens, so if reduce to drive angle, then can produce the zone of wanting duplicate detection.Therefore,, change the driving angle, can cause shorten detection time through utilizing the angle of depression like this in order to omit unnecessary detection.And then say it, owing to omitted unnecessary detection, so in obstacle detector 30, the data volume that handle reduces, so can handle by reduced data.

There is the low zone of possibility in another device as being used to omit unnecessary detection at barrier in addition, strengthens the method that drives angle (perhaps simply not carrying out the detection in this zone).In addition, in the zone of the direction that does not detect the people (for example, being judged as position A1, B1, B2, E1, E2 (with reference to Figure 14) when area E (with reference to Fig. 5) is had no talent), it also is effective strengthening and driving angle (perhaps simply not carrying out the detection in this zone).In addition, have in area E under people's the situation, A1, B1, B2, E1, E2 in the position preferably reduce to drive angle.

< wall is apart from the high precision int of instrumentation >

This wall apart from instrumentation in order to improve the precision of confirming from the distance numbers of indoor set wall WC, left side wall WL, right side wall WR to the front.That is, when establishing indoor set and being installed in the metope in the room of rectangle when overlooking usually,, just can analogize the position of corner portion according to its position as long as know the position of front wall WC, left side wall WL and right side wall WR.Corner portion becomes the roughly angle of 90 degree; Shown in figure 31; From hyperacoustic back wave that ultrasonic sensor 32 sends, must return the direction of transmission, so the distance of portion to the corner through being easy to correctly detect, in fact measure; With according in fact measure to positive with about the distance of portion calculated with trigonometric function of the distance of metope WC, WL, WR to the corner compare, can confirm the front and about the correctness of position of metope WC, WL, WR.The distance mistake that will arrive this illumination because this instrumentation possibly detect illumination etc. when wall detects is identified as the distance of metope, so important effect is played in the affirmation of corner portion.

Figure 32 be with the distance numbers (for example) of the front of confirming as described above and left and right sides metope WC, WL, WR with reference to table 20 at this as distance numbers temporarily, be used to revise the flow chart of this interim distance numbers.

Try to achieve positive with about the interim distance numbers of metope WC, WL, WR the time (step S111), in step S112, the angle and distance of the corner portion about calculating.Wherein, the angle of corner portion be meant with the angle of the horizontal direction of using in order to confirm each address likewise, see the angle of measuring from the datum line in left side (above-mentioned β) to the right from indoor set.

The angle of the corner portion (the corner portion of front wall WC and left side wall WL) in left side; Table 26 based on calculating with trigonometric function according to the interim distance numbers of the interim distance numbers of front wall WC and left side wall WL confirms, the angle of the corner portion on right side (the corner portion of front wall WC and right side wall WR) is likewise definite by the table 27 of calculating with trigonometric function according to the interim distance numbers of the interim distance numbers of front wall WC and right side wall WR.

[table 26]

Table is judged in the corner, left side

[table 27]

Table is judged in the corner, right side

On the other hand, the interim distance numbers of the corner portion about arriving is confirmed based on the table 28 of calculating with trigonometric function according to the interim distance numbers of the interim distance numbers of front wall WC and left side wall WL or right side wall WR.

[table 28]

A left side/corner, right side is apart from judging table

Wherein, in table 26, table 27, the table 28, the minimum of a value of establishing the interim distance numbers of front wall WC is 5, is because imagination front wall WC can not be present in the position nearer than 3m.In addition; The distance of wall WL and right side wall WR is that the situation of 0m in fact also exists to the left side; But because the situation of ultrasonic sensor 32, because of echo can't be detected closely, so the minimum of a value of the interim distance numbers of left side wall WL and right side wall WR is set at 2.

In addition, there is scope in corresponding hyperacoustic transmission time with distance numbers (perhaps interim distance numbers), so the distance of the reality corresponding with distance numbers has certain scope (error), and the distance numbers of table 29 expression identification and the relation of actual range.

[table 29]

Wherein, in table 7 or the table 8, distance numbers=12 are set at limiting value (maximum X), and the room that the imagination lengthwise is perhaps grown crosswise, the maximum with distance numbers in the table 29 was set at for 15 (being equivalent to detect apart from 10.9m).

In step S113, with step S112 in the angle corresponding address confirmed detect action with ultrasonic sensor 32, instrumentation arrives the actual range of corner portion.At next procedure S114; To try to achieve among the step S112 with to the suitable distance of interim distance numbers of left and right sides corner portion; Compare with the step S113 actual range of measuring of portion of falling into a trap to the left and right sides corner; If it is correct that its difference, then is regarded as the interim distance numbers of front that step S111 tries to achieve and left and right sides metope WC, WL, WR in ± 1, in step S115, interim distance numbers is confirmed as correct distance numbers.

On the other hand; If the difference with the suitable distance of a certain side's in corner, left side portion and corner, the right side portion interim distance numbers and actual range is not ± 1 in; The interim distance numbers that then is regarded as left side wall WL or right side wall WR is wrong, and in step S116, establishing distance numbers is 15 (maximums).In addition; If the difference with the suitable distance of corner, left side portion and corner, the right side both sides' of portion interim distance numbers and actual range is not ± 1 in; The interim distance numbers that then is regarded as positive WC is wrong, in step S116, distance numbers is made as 15 (maximums).

The range accuracy of confirming like this to positive and left and right sides metope WC, WL, WR is higher; The size in room can be discerned in position through discerning front and left and right sides metope WC, WL, WR; Through correspondingly controlling wind direction or air quantity, can reach energy-conservation and comfortable air conditioning with wind direction change unit or indoor fan 8 with the size in room.In addition, not only can carry out above-mentioned barrier expeditiously and hide control or people's wall, can also effectively be applied to wait other control with the corresponding air conditioning control of position or room shape (afterwards stating) that is provided with of indoor set near control.

Wherein, In this embodiment; In order to realize the high precision int of wall apart from instrumentation, after detecting positive and left and right sides metope, detect corner portion, also can disposable detection all metopes of 180 angular ranges of spending roughly; Write down after all distances, extract the range data of front and left and right sides wall and the range data of the corner portion of trying to achieve according to this range data and the two is compared.But the latter's method need write down the memory of front and the unnecessary data beyond left and right sides wall and the corner portion, so more favourable from this method of putting the former of conserve memory.

In addition; With reference to the address of wanting instrumentation of table 5 explanation, see from indoor set, in vertical direction 5 degree～80 degree; Set in the scope of 10 degree～170 degree on the horizontal direction; And since around the outside of metope do not have the barrier that hinders air-flow, so with the outside corresponding address of on every side metope, also can be set at the instrumentation that does not carry out ultrasonic sensor 32.

With indoor set the corresponding air conditioning control of position or room shape is set

Figure 33 representes to be used to discern the flow chart that position and room shape are set of indoor set.

As stated; When having confirmed the distance numbers of positive and left and right sides metope WC, WL, WR (step S121), at step S122, whether the distance numbers of wall WL equals 2 on the left of judging; If equal 2; Then, be judged to be indoor set, in step S124, carry out first left and right sides blade control (afterwards stating) near the configuration of wall WL ground, left side (" being provided with ") near the right side wall to indoor set at step S123.

On the other hand; If the distance numbers of left side wall WL is not 2, then in step S125, judge whether the distance numbers of right side wall WR equals 2; If equal 2; Then in step S126, be judged to be indoor set, in step S127, carry out second left and right sides blade control (afterwards stating) near the configuration of wall WR ground, right side (to indoor set " the left side wall is near configuration ").

In addition, if the distance numbers of right side wall WR is not 2, then in step S128, the position that is provided with that is judged to be indoor set is metope central portion (central authorities is provided with), transfers to step S129.

In step S129; Distance numbers with front wall WC; Compare with the distance numbers of left side wall WL and the distance numbers sum of right side wall WR; If being judged to be the former is more than the latter, then in step S130, being judged to be room shape is " lengthwise ", in step S131, carries out blade control (afterwards stating) and the 3rd left and right sides blade control (afterwards stating) about in the of first.

On the other hand; In step S129; Be judged to be the distance numbers of front wall WC; During less than the distance numbers sum of the distance numbers of left side wall WL and right side wall WR, in step S132, being judged to be room shape is " growing crosswise ", in step S133, carries out about in the of second blade control (afterwards stating) and controls (afterwards stating) with the 4th left and right sides blade.

Figure 34 A, Figure 34 B and Figure 34 C, the swing range of left and right sides blade 14 under expression central authorities' situation of being provided with, being provided with respectively near right side wall setting or near the left side wall.

When central authorities are provided with, hide under the situation of control not carrying out above-mentioned barrier, shown in Figure 34 A, left and right sides blade 14 carries out wind direction control automatically usually, shakes action with angular range (each 80 degree adds up to 160 degree the for example) left and right symmetrically of regulation.

On the other hand, under near right side wall setting or situation, there is not the possibility that the people is arranged on the approaching side surface direction, can causes waste so the overall region under wind direction is controlled is automatically usually shaken near the setting of left side wall.So, under near right side wall setting or situation about being provided with, make left and right sides blade 14 from just shaking action towards rightabout with approaching side near the left side wall.

Further in detail; When being provided with near the right side wall, not carrying out barrier hides under the situation of control; Carry out first left and right sides blade control shown in Figure 34 B; Set the swing range of left and right sides blade 14 less, left and right sides blade 14 shakes action from the front to right-hand angular range with regulation (80 degree).Perhaps, 5 degree of also can taking back from the front shake action to right-hand angular range (80 degree) with regulation.

In addition; When being provided with near the left side wall, not carrying out barrier hides under the situation of control; Carry out second left and right sides blade control shown in Figure 34 C, set the swing range of left and right sides blade 14 less, left and right sides blade 14 shakes action from the front to left with the angular range of stipulating (80 degree).Perhaps, 5 degree that also can take over from the front shake action to left with the angular range (80 degree) of regulation.

On the other hand; Do not carry out under the situation of the usually automatically wind direction control that barrier hides control blade 12 up and down and shake action up and down with the angular range of regulation; And be provided with and be under the situation of room shape of lengthwise in central authorities; Air-flow is arrived at a distance, thus in blade control first about, for the angular range of afore mentioned rules slightly (for example 5 degree) shake action to top correction (lifting).Otherwise, central authorities be provided with and situation for the room shape of growing crosswise under, air-flow is arrived at a distance, thus in blade control second about, to the angular range of afore mentioned rules slightly (for example 5 degree) correction (falling) downwards shake action.

In addition, be provided with and be under the situation of room shape of lengthwise, arrive the close together of left and right sides metope in central authorities; So in the 3rd left and right sides blade control, be set at little (each 75 degree for example, of angular range than the regulation of setting during wind direction is controlled automatically usually of shaking action; Add up to 150 degree), and the air quantity of indoor fan 8 is increased, relative therewith; Under the situation of the room shape of growing crosswise, need on left and right directions, make air-flow arrive wider scope, so in the 4th left and right sides blade control; Be set at angular range than the regulation of setting in the common automatically wind direction control of shaking action big (for example, about each 85 degree, add up to 170 degree).

In addition, in this embodiment, use ultrasonic type range sensor, but also can replace the ultrasonic type range sensor, adopt the photo-electric range sensor as the distance detecting unit.
