The specific embodiment

Below, with reference to accompanying drawing, embodiments of the present invention are described.

General domestic air conditioner is usually by constituting by interconnected off-premises station of refrigerant pipeline and indoor set, and Fig. 1 and Fig. 2 represent the indoor set of air conditioner of the present invention.

Indoor set has body 2 and the movable front panel of the 2a of front openings portion of Switch main body 2 (hereinafter referred is a front panel) 4 freely, and when air conditioner stopped, front panel 4 was close to body 2, closed the 2a of front openings portion; Otherwise when air-conditioner operation, front panel 4 moves to the direction that deviates from body 2, opens the 2a of front openings portion.In addition, Fig. 1 represents that front panel 4 closes the state of the 2a of front openings portion, and Fig. 2 represents that front panel 4 opens the state of the 2a of front openings portion.

As shown in Figure 3, inside at body 2, has heat exchanger 6, be used for and carry out the heat exchange after-blow to indoor fan 8 by the room air of 2a of front openings portion and top peristome 2b input at heat exchanger 6, to the air with heat exchange blow to indoor blow-off outlet 10 when carrying out switch with the blow-off direction of air towards the blade up and down 12 of change up and down, with with the blow-off direction of air towards about the left and right sides blade (not shown) of change, on the body 2 of peristome 2a below, blow-off outlet 10 sides that the 2a of peristome in front that freely swings by intermediate blade driving mechanism 16 is installed are carried out the intermediate blade 14 of switch in front.In addition, front panel 4 tops are connected with body 2 tops by two arms 18,20 that are arranged on its two ends, by the CD-ROM drive motor (not shown) that is connected with arm 18 is driven control, when air-conditioner operation, move to oblique front upper place the position (closing position of the 2a of front openings portion) when front panel 4 is stopped by air conditioner.In addition, blade 12 is connected with body 2 bottoms by two arms 22,24 that are located at its two ends up and down, and its driving method is illustrated hereinafter.

As Fig. 1 (b) with (c), the top of panel 4 in front, a plurality of (for example 5) sensor unit 26,28,30,32,34 as apparatus for detecting human body to be installed from the outstanding state of the principal plane of front panel 4, these sensor units 26,28,30,32,34 are kept by sensor stand 36 as shown in Figure 4.In addition, shown in Fig. 1 (a), apparatus for detecting human body is covered by cover 5, and the state behind the cover 5 is taken off in Fig. 1 (b) expression.

Shown in Fig. 5 (a), why each sensor unit 26,28,30,32,34 is arranged on the top of front panel 4, be field range (position of human body critical region described later), guarantee the far-end visual field to greatest extent in order to enlarge each sensor unit 26,28,30,32,34.In addition, shown in Fig. 5 (b), when beginning running moves to the place ahead by making front panel 4 by stop position, can guarantee farther field range, simultaneously, shown in Fig. 5 (c), by making front panel 4 move to oblique upper, the scope of can further broadening one's vision by stop position.In addition, the position of each sensor unit 26,28,30,32,34 is not limited only to the top of front panel 4, and, when even panel is not movable in front, by top or the body top that apparatus for detecting human body is installed in front panel, compare the scope of also can broadening one's vision when being installed in the bottom.

In addition, shown in Fig. 5 (d), by each sensor unit 26,28,30,32,34 also is provided with from the principal plane of front panel 4 is outstanding, each sensor unit 26,28,30,32,34 can be configured in more the place ahead, shown in Fig. 5 (b)～(d), can avoid the generation at the dead angle that the component parts (for example up and down blade 12 or make the 2a of front openings portion be the front panel 4 etc. of open state) because of indoor set causes, the scope of broadening one's vision.

In the present embodiment,, therefore, when front panel 4 makes the 2a of front openings portion be open state, move, become further forwards outstanding along with moving of front panel 4 because each sensor unit 26,28,30,32,34 is located on the front panel 4.

In addition, sensor unit 26 is made of circuit substrate 26a, the human body detection sensor (not shown) that is installed in the lens 26b on the circuit substrate 26a and is installed in lens 26b inside, and other sensor unit 28,30,32,34 also is same structure.And, human body detection sensor is by for example by surveying the infrared ray from human body radiation, the infrared ray sensor that the someone surveys is constituted, according to the pulse signal that the variation of the infrared ray amount that detects according to infrared ray sensor is exported, judge by circuit substrate 26a whether the people is arranged.That is, circuit substrate 26a is as the people/unmanned identifying unit that has that the someone judges is played a role.Below, it is right that mutually paired sensor and lens are called sensor leads.

At this,, shown in the side view of Fig. 6, consider sensors configured unit 26,28,30,32,34 on the surface of ball Z arbitrarily for obtaining the search coverage of direction all around.At this moment, the optical axis that the sensor leads of each sensor unit 26,28,30,32,34 is right intersects in the center P of ball Z, is not on the position of antarafacial.When observing, because become the outstanding configuration of direction forwards, backwards, so be difficult to realize the miniaturization of apparatus for detecting human body in the surperficial upper sensor unit 26,28,30,32,34 of ball Z by indoor set.

In addition, in order to suppress the outstanding of aforesaid sensor unit, also consider as shown in Figure 7 to cut ball Z arbitrarily, dispose each sensor unit 26,28,30,32,34 at the intersection point place of the optical axis (not being the position of antarafacial) of plane X and each sensor unit 26,28,30,32,34 with plane X arbitrarily.At this moment, the configuration of sensor unit 26,28,30,32,34 is shown in the front elevation of Fig. 8, though the outstanding minimizing of fore-and-aft direction, but sensor unit 26 disperses on the direction with 30 such search coverage being configured in length and breadth of sensor unit different with the distance of indoor set, in the miniaturization of apparatus for detecting human body limitation is arranged.

Therefore, in the present embodiment, the right optical axis of the sensor leads of sensor unit 26,28 at grade, though the right optical axis of the sensor leads of sensor unit 30,32,34 is on another same level, but the right optical axis of the sensor leads of optical axis that the sensor leads of sensor unit 26,28 is right and sensor unit 30,32,34 is not at grade, in order to form the position of antarafacial, separately circuit substrate 26a, 28a, 30a, 32a, 34a are tilted on the angle of regulation, and are installed on the sensor stand 36.

Like this, the right optical axis of sensor leads by the sensor unit that the distance of search coverage and indoor set is different is formed on the antarafacial position, as depicted in figs. 1 and 2, sensor 26,28,30,32,34 can be realized the miniaturization of apparatus for detecting human body along laterally roughly linearly configuration.

In addition, though to the different sensor units of the distance from indoor set to the sensor search coverage along laterally roughly the examples of linearly configuration be described, the different sensor unit of left and right directions along the short transverse of indoor set roughly the situation of linearly configuration also be same.

As mentioned above, according to present embodiment, in a plurality of sensor units 26,28,30,32,34 on being arranged on indoor set, the right optical axis of sensor leads of the sensor unit that the area of visual field of this sensor unit is different with the distance of air conditioner is in the position of antarafacial each other, therefore, sensor unit 26,28,30,32,34 can be provided with by the outstanding modes of the front panel 4 of indoor set avoiding, thereby makes the miniaturization of apparatus for detecting human body become possibility.

In addition, by sensor unit 26,28,30,32,34 is roughly linearly disposed, sensor unit 26,28,30,32,34 makes the miniaturization of sensor unit 26,28,30,32,34 become possibility in not dispersion of direction in length and breadth.

In addition, as mentioned above, sensor leads is set on apparatus for detecting human body, and right optical axis is positioned at a plurality of sensor units 26,28,30,32,34 of antarafacial position, and towards the mode of visual field direction they are disposed with the right optical axis of each sensor leads, so can form a plurality of search coverages on the range direction of observing from apparatus for detecting human body and a plurality of search coverages on the left and right directions, simultaneously, make the miniaturization of lens become possibility by improving light gathering efficiency.

Fig. 9 represents that sensor unit 26,28,30,32,34 separately can be to whether the someone surveys with lower area by the position of human body critical region of sensor unit 26,28,30,32,34 detections.

Sensor unit 26: regional A+C+D

Sensor unit 28: area B+E+F

Sensor unit 30: zone C+G

Sensor unit 32: region D+E+H

Sensor unit 34: regional F+I

Promptly, in the indoor set of air conditioner of the present invention, the area part that zone that sensor unit 26,28 can be surveyed and sensor unit 30,32,34 can be surveyed is overlapping, and whether usage quantity has the people than the sensor that the sum of regional A～I lacks among promptly detectable each regional A～I.

In addition, by at least three human body detection sensors are installed on indoor set top, can two dimension hold the indoor human body position with respect to the far and near direction of indoor set and left and right directions where, promptly the flooring where.Search coverage when Figure 10 represents to be provided with three human body detection sensor unit, in the example of Figure 10, whether whether the near zone of indoor set has the people to be surveyed by a human body detection sensor, have the people to be surveyed by two human body detection sensors away from the zone of indoor set.

Return Fig. 9 and further present embodiment is illustrated, in the following description, sensor unit 26,28,30,32,34 is called first sensor 26, second sensor 28, the 3rd sensor 30, four-sensor 32, the 5th sensor 34.In addition, zone C, D, E, F are surveyed by two sensors, and therefore, with respect to the overlapping region, the zone (regional A, B, G, H, I) beyond the overlapping region is surveyed by a sensor, so be called as conventional zone.And the overlapping region is divided into overlapping region C, the D in left side and overlapping region E, the F on right side.

Figure 11 is used to use first～the 5th sensor 26,28,30,32,34, on each regional A～I, set the flow chart of aftermentioned region characteristic, Figure 12 is for using first～the 5th sensor 26,28,30,32,34, the arbitrary region the flow chart whether someone judges to regional A～I, with reference to these flow charts, as described below, the decision method of people's position is described.

At step S1, in specified period T1 (for example 5 seconds), judge at first whether the overlapping region in left side has the people, at step S2, condition is exported zero clearing with the sensor of regulation according to the rules.

The decision method of overlapping region, table 1 expression left side, arbitrary as a result the time when what meet three reaction results shown in the table 1, just with the output zero clearing of first sensor 26 and the 3rd sensor 30.At this, 1 is defined as and responds, and 0 is defined as reactionlessly, and zero clearing is defined as 1 → 0.

Table 1: the overlapping region, left side is judged

At step S3, in afore mentioned rules period T 1, judge further whether the overlapping region, right side has the people, at step S4, condition is exported zero clearing with the sensor of regulation according to the rules.

The decision method of table 2 expression overlapping region, right side, arbitrary as a result the time when what meet three reaction results shown in the table 2, just with the output zero clearing of second sensor 28 and the 5th sensor 34.

Table 2: the overlapping region, right side is judged.

In addition, arbitrary as a result time the in meeting six reaction results shown in table 1 and the table 2 just with the also zero clearing of output of four-sensor 32, transfers to step S5.In step S5, in afore mentioned rules period T 1, whether conventional zone has the people to judge according to table 3, in step S6, all the sensors is exported zero clearing.

Table 3: conventional regional determination

Sensor	Reaction result	Location determination
			First sensor	1	A
Second sensor	1	B
			The 3rd sensor	1	G
Four-sensor	1	H
			The 5th sensor	1	I

Further, with reference to Figure 13, come determinating area A, B, C whether to have people's situation to describe to only using output from first～the 3rd sensor 26,28,30.

As shown in figure 13, in the period T 1 before time point t1, when first～the 3rd sensor 26,28,30 is OFF (no pulse), judge regional A, B, C unmanned (A=0, B=0, C=0) at time point t1.Then, during the time point t2 after 1, when the 26 output ON signals (pulse is arranged) of first sensor only, when the second and the 3rd sensor 28,30 is OFF from time point t1 to period T, judgement has the people at time point t2 zone A, area B, C unmanned (A=1, B=0, C=0).Further, during the time point t3 after 1, when the first and the 3rd sensor 26,30 output ON signals, when second sensor 28 is OFF from time point t2 to period T, judgement has the people in time point t3 zone C, regional A, B unmanned (A=0, B=0, C=1).After this same, in each period T 1, judge whether each regional A, B, C have the people.

In the practice; whether the someone judges in which zone of 26,28,30,32,34 couples of regional A～I of use first～the 5th sensor; according to this result of determination, each regional A～I differentiated be first area (often versatilely) that the people is often arranged, the short second area of time (zone that the zone that the people only passes through, the time of staying are short etc. are by the zone) that the people is arranged, very short the 3rd zone (the non-life that people such as wall, window go hardly is regional) of time that the people is arranged.Below, first area, second area, the 3rd zone are called life classification I, life classification II, life classification III, also life classification I, life classification II, life classification III can be called the zone of region characteristic I, the zone of region characteristic II, the zone of region characteristic III.In addition, also life classification I (region characteristic I), life classification II (region characteristic II) can be generically and collectively referred to as life zone or residential area (zone of people's life), relative therewith, the classification III (region characteristic III) that will live is called non-life regional or non-residential area (zone that the people does not live), according to the people with not the frequency zone of will living be divided into big class.

This differentiates the later step enforcement at the step S7 of the flow chart of Figure 11, and this method of discrimination is described with reference to Figure 14 and Figure 15.

Figure 14 is illustrated in the situation that the indoor set of air conditioner of the present invention is set among the LD of the 1LDK that is made of a Japanese room, LD (living room hold concurrently dining room) and kitchen, the place that the people is often arranged of the subject of region representation shown in ellipse report among Figure 14.

As mentioned above, in each period T 1, to whether the someone judges among each regional A～I, reaction result (judgement) as period T 1, output 1 (responding) or 0 (reactionless), after implementing this test repeatedly repeatedly, in step S7, judge the accumulation duration of runs of the air conditioner that whether has passed through regulation.In step S7,, turn back to S1 when being judged to be when not passing through the stipulated time; On the other hand, when being judged to be when having passed through the stipulated time, just the reaction result of accumulating in this stipulated time and two threshold values with each regional A～I compare, and differentiate which zone that each regional A～I belongs to life classification I～III respectively.

Figure 15 with reference to expression long-term accumulated result, more specifically, set first threshold and second threshold value littler, in step S8 than first threshold, whether the long-term accumulated result to each regional A～I carries out judging than first threshold more, is judged to be many zones and is judged to be life classification I in step S9.In addition, in step S8, when the long-term accumulated result who judges each regional A～I than first threshold after a little while, in step S10, whether the long-term accumulated result who judges each regional A～I is more than second threshold value, be judged to be many zones and in step S11, be judged to be life classification II, in step S12, be judged to be life classification III and be judged to be few zone.

In the example of Figure 15, area E, F, I be by the differentiation classification I that lives that makes a living, and area B, H be by the differentiation classification II that lives that makes a living, and regional A, C, D, G are by the differentiation classification III that lives that makes a living.

In addition, Figure 16 is illustrated in the situation that is provided with the indoor set of air conditioner of the present invention among the LD of another 1LDK, and Figure 17 represents that with the long-term accumulated result under this situation be the result that the basis is judged each regional A～I.In the example of Figure 16, zone C, E, G are judged as life classification I, and regional A, B, D, H are judged as life classification II, and regional F, I are judged as life classification III.

In addition, the differentiation of above-mentioned zone characteristic (life classification) repeated once every one period stipulated time, as long as the indoor sofa of differentiating at need that disposes, dining table etc. do not move, it is almost constant then to differentiate the result.

Then, with reference to the flow chart of Figure 12, the final decision whether people is arranged among each regional A～I is illustrated.

Step S1～S6 in the flow chart of step S21～S26 and above-mentioned Figure 11 is identical, therefore omits its explanation.In step S27, judge the reaction result of the period T 1 that whether obtains stated number M (for example 15 times), when determination cycles T1 does not reach stated number M, return step S21; On the other hand, when period T 1 reaches stated number M, in step S28, accumulate number of times between the stage of reaction, calculate number of times between the accumulation stage of reaction once with the adding up to of reaction result of period T 1 * M.Repeated multiple times is calculated number of times between this accumulation stage of reaction, in step S29, judges and whether to obtain stipulated number that (for example, the result of calculation of number of times between accumulation stage of reaction N=4) when being judged to be when not reaching stipulated number, turns back to step S21; On the other hand, when judgement reaches stipulated number, in step S30,, infer whether each regional A～I has the people based on number of times between the accumulation stage of reaction of the region characteristic judged and stipulated number.

In addition, in step S31, the calculation times (N) of number of times between the accumulation stage of reaction is subtracted 1, turn back to step S21, repeat the calculating of number of times between accumulation stage of reaction of stipulated number thus.

Table 4 expression is up-to-date once, and (experience of the reaction result of time T 1 * M), in the table 4, for example the meaning of ∑ A0 is a number of times between accumulation stage of reaction once of regional A.

Table 4

At this, with number of times between 1 time the accumulation stage of reaction before the ∑ A0 is ∑ A1, and be ∑ A2...... with number of times between its accumulation stage of reaction of 1 time before more, according to the experience (for example, 4 times) of the several in past in zone, life classification and between the accumulation stage of reaction number of times infer whether the people is arranged.

Then, after elapsed time T1 * M, same after above-mentioned whether someone judges, by past 4 times course, life classifying and dividing and between the accumulation stage of reaction number of times infer whether the people is arranged.

Promptly, in the indoor set of air conditioner of the present invention, usage quantity comes whether the someone infers than the sensor that the sum of critical region A～I lacks, therefore the possibility that in the deduction of each specified period, all has the position of judging the people by accident, so no matter whether be the overlapping region, avoid under independent specified period, inferring people's position, the resulting region characteristic of regional determination result of each specified period of long-term accumulated and the regional determination result of each specified period are accumulated N time, according to past of number of times between the accumulation stage of reaction in each zone of trying to achieve through always inferring people's location, obtain the inferred results of the high people's of probability position thus.

To whether the someone judges, it is illustrated in and is set to T1=5 second table 5, the deduction M=12 time the time has people's required time and infers unmanned required time in aforesaid mode.

Table 5

The life classification	Inferring has the people	Infer unmanned
			I	60 seconds (soon)	240 seconds (slowly)
II	120 seconds (standard)	180 seconds (standard)
			III	180 seconds (slowly)	120 seconds (soon)

Like this, utilize the indoor set of air conditioner of the present invention, after will needing the zone of air-conditioning to be divided into a plurality of regional A～I by first～the 5th sensor 26,28,30,32,34, determine that (life classifying and dividing I～III), changing according to the region characteristic of each regional A～I has the people to infer required time and unmannedly infer required time again for the region characteristic of each regional A～I.

That is, after changing the air-conditioning setting, till air-supply, need about 1 minute, therefore, in the short time (for example several seconds), change the air-conditioning setting and not only impair comfortableness, and for the place that is about to leave in the forces, from energy-conservation angle, be not preferably and often it carried out air conditioning.Therefore, survey at first among each regional A～I whether the people is arranged, especially the air-conditioning of people region is set optimization.

Particularly, with the zone that is judged to be life classification II whether the someone infers that the needed time is standard, in the zone that is judged to be life classification I, to infer that than the shorter time interval of zone that is judged to be life classification II the people is arranged; Relative therewith, unmanned to infer under the situation that the people is disappeared by this zone than the longer time interval of zone that is judged to be life classification II, thus,, the unmanned mode of inferring that required time prolongs is set so that someone is inferred that required time shortens.Otherwise, in the zone that is judged to be life classification III, to infer that than the longer time interval of zone that is judged to be life classification II the people is arranged; Relative therewith, unmanned to infer when the people is disappeared by this zone than the shorter time interval of zone that is judged to be life classification II, thus,, the unmanned mode of inferring that required time shortens is set so that someone is inferred that required time prolongs.In addition, as mentioned above, the life classification in each zone as a result changes according to long-term accumulated, and correspondingly, the someone infers that the setting of required time and unmanned deduction required time is also variable.

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

Wind direction control during heating is by before wind direction is controlled at the people's who is inferred as the people zone vola, and warm braw is reached near the vola; Wind direction control during refrigeration is by wind direction being controlled at top, the people crown, making cold wind reach overhead.Wind direction can be by the rotating speed of fan 8, the angle of blade 12 or left and right sides blade is regulated up and down.

Figure 18 represents the up and down rotation control of blade 12, and when air conditioner stopped, shown in Figure 18 (a), front panel 4, blade 12 and intermediate blade 14 all were in closure state up and down.

When refrigeration, arrive intelligent's overhead (refrigeration roof air-flow) for making the air (cold wind) that blows out, arrive the state shown in Figure 18 (c) by the state shown in Figure 18 (a) through the state shown in Figure 18 (b).At first, drive control arm 18,20, make front panel 4 deviate from the 2a of front openings portion, simultaneously, drive control arm 22,24, making up and down, blade 12 deviates from blow-off outlet 10.

Under the state of Figure 18 (c), the air that blows out from blow-off outlet 10 causes horizontal direction by blade 12 up and down, because the downstream side end of blade 12 is crooked upward up and down, so air can be sent to the room far-end.At this moment, the top of blow-off outlet 10, promptly the below of front panel 4 is stopped up by intermediate blade 14, the part of air that is blown out by blow-off outlet 10 can not caused the front openings 2a of portion.

On the other hand, when heating,, arrive the state shown in Figure 18 (d) through the state shown in Figure 18 (b) by the state shown in Figure 18 (a) because make near the air (warm braw) (heating vola air-flow) intelligent's vola that blows out.Under the state of Figure 18 (d), the air that blows out from blow-off outlet 10 causes oblique below by blade 12 up and down, because the downstream side end of blade 12 is to the base side bending up and down, so the warm air that gathers the top, room easily can be delivered to the below, room.

In addition, utilize mode shown in Figure 18 (e) during refrigeration before stable, this mode is to human body blow out air (towards the human body air-flow).

The setting rotating speed of the fan 8 when Figure 19 represents the operation of air conditioner of each regional A～I, A1, A2, A3 be with indoor set respectively at a distance of closely, middle distance, the remote reference rotation speed in zone, the speed discrepancy that A4 causes because of regional difference when identical for distance, for example, set like that as shown below respectively.

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

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

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

A4:100rpm (changes in temperature are general)

At this, as expression each zone and distance indoor set, with the performance with the position relation of indoor set such as indoor set front angulation, difference of height, introduce the manifestation mode that is called as relative position.

In addition, in each zone, utilize the manifestation mode that is called as air-conditioning demand degree to represent the degree of carrying out air conditioning easily, being difficult to carry out air conditioning, air-conditioning demand degree is high more, be difficult to carry out air conditioning more, air-conditioning demand degree is low more, carries out air conditioning easily more.For example, far away more apart from indoor set, the air that blows out is difficult to reach more, be difficult to more carry out air conditioning, so air-conditioning demand degree is high more.That is, air-conditioning demand degree with the relative position of indoor set is had substantial connection, in the present embodiment,, determine air-conditioning demand degree according to the relative position of distance indoor set.

Therefore, mean: when each regional A～I was carried out air conditioning, air-conditioning demand degree was high more, and the setting rotating speed of fan 8 is just set highly more.That is, the position that need carry out the air conditioning zone is far away more apart from indoor set, and the setting speed setting of fan 8 must be high more, simultaneously, under the identical situation of the distance of distance indoor set, the relative zone of departing to the left and right, the front of indoor set, the setting rotating speed of fan 8 is just set highly more.In addition, be under one the situation in the zone that need carry out air conditioning, be the setting rotating speed (air quantity) in this zone with the setting speed setting of fan; Under the zone that need carry out air conditioning is a plurality of situation, be the setting rotating speed in the high zone of air-conditioning demand degree with the setting speed setting of fan.

In addition, the blade up and down 12 when Figure 20 represents to heat and the set angle of left and right sides blade, B1, B2, B3 be respectively with indoor set at a distance of closely, middle distance, the remote benchmark blade angle up and down in zone, the differential seat angle of the blade up and down that B4 causes because of regional difference when identical for distance, relative therewith, C1 and C2 be about the zone benchmark left and right sides blade angle (transferring forward counterclockwise to), C3 is the differential seat angle because of the regional different left and right sides blades that cause with C4, for example, set like that as shown below respectively.In addition, the angle of blade 12 is meant up and down, be at blade under the state of top projection, and be 0 ° when being level with the front and back end connecting line of blade, be benchmark with this position, the angle when counterclockwise measuring.

B1：70°

B2：55°

B3：45°

B4：10°

C1：0°

C2：15°

C3：30°

C4：45°

Promptly, when indoor set near zone A or B are heated, blade 12 is set at first angle (for example 70 °) up and down, simultaneously, with the speed setting of fan 8 be first rotating speed (for example, 800rpm), wind direction is controlled at the edge (people's front, vola) of the indoor pusher side among regional A or the B, warm braw is arrived near the vola.In addition, to with indoor set when zone C, D, E or the F of middle distance heats, blade 12 up and down is set at second angle (for example 55 °) less than first angle, simultaneously, with the speed setting of fan 8 is second rotating speed (for example 1000rpm) that is higher than first rotating speed, wind direction is controlled at the edge (people's front, vola) of the indoor pusher side of zone C, D, E or F, warm braw is arrived near the vola.In addition, when to indoor set when farthest regional G, H or I heat, blade 12 is set at the third angle degree (for example 45 °) less than second angle up and down, simultaneously, with the speed setting of fan 8 is the 3rd rotating speed (for example 1200rpm) that is higher than second rotating speed, wind direction is controlled at the edge (people's front, vola) of the indoor pusher side of regional G, H or I, warm braw is arrived near the vola.

Figure 21 represents to start or the blade up and down 12 the during refrigeration of unstable region and the set angle of left and right sides blade, E1, E2, E3 be with indoor set respectively at a distance of closely, middle distance, the remote benchmark blade angle up and down in zone, the differential seat angle of the blade up and down that E4 causes because of regional difference when identical for distance, relative therewith, F1 and F2 be about the zone benchmark left and right sides blade angle (transferring forward counterclockwise to), F3 is the differential seat angle because of the regional different left and right sides blades that cause with F4, for example, set like that as shown below respectively.In addition, start the situation when being meant the air conditioner entry into service, unstable region be meant the room conditioning state do not reach the state of impose a condition (for example design temperature).

E1：50°

E2：35°

E3：25°

E4：10°

F1：0°

F2：15°

F3：25°

F4：35°

In addition, the blade up and down 12 when Figure 22 represents the stability region refrigeration and the set angle of left and right sides blade, benchmark when H1 is the roof air-flow is blade angle up and down, benchmark when H2 is the release air-flow is blade angle up and down, and H3 is the differential seat angle because of the blades up and down that cause apart from difference, and is relative therewith, I1 and I2 be about the zone benchmark left and right sides blade angle (transferring forward counterclockwise to), I3 and I4 for example, set respectively as shown below like that for the differential seat angle because of the regional different left and right sides blades that cause.In addition, the stability region is meant that present room conditioning state reaches the state of impose a condition (for example design temperature).

H1：180°

H2：190°

H3：5°

I1：0°

I2：15°

I3：25°

I4：35°

At this, the roof air-flow is meant, shown in Figure 18 (c), makes blade 12 up and down be positioned at the bottom of blow-off outlet 10, the air-flow when blowing out wind and being born and be sent by the concave surface of blade fully; The release air-flow is meant, make the position of leaning on top when blade 12 is positioned at than the roof air-flow up and down slightly, make a part (trace) that blows out wind also flow to the convex side (below of blade) of blade, thereby make the convex surface of blade be difficult to that dewfall takes place and the air-flow when under this state, wind being sent.

When the near zone A of indoor set or B are freezed, blade 12 is set at the below of only hanging down predetermined angular (for example 5 °) than level up and down, the speed setting of fan 8 is the first rotating speed (rotating speed that lacks than first rotating speed in when heating, 700rpm for example), so that cold wind arrives the overhead of regional A or B, the mode that makes cold air be spray shape whereabouts is set.In addition, when to indoor set when zone C, D, E or the F of middle distance freezes, blade 12 is set at approximate horizontal up and down, with the speed setting of fan 8 is second rotating speed that the is higher than first rotating speed (rotating speed that second rotating speed during than heating lacks, 900rpm for example), make cold wind arrive the overhead of zone C, D, E or F.When to indoor set when farthest regional G, H or I freeze, blade 12 is set at the top than the only high predetermined angular of level (for example 5 °) up and down, with the speed setting of fan 8 is the 3rd rotating speed that the is higher than second rotating speed (rotating speed that the 3rd rotating speed during than heating lacks, 1100rpm for example), make cold wind arrive the overhead of regional G, H or I.

Then, with reference to the flow chart of Figure 23, the wind direction control that the quantity in the zone of air-conditioning is as required carried out is illustrated.

After the air conditioner entry into service, in step S41, at first to whether the someone judges among regional A～I, in step S42, when only there being a zone to be determined the people, that is, and when needing the zone of air-conditioning to be one, in step S43, carry out air conditioning with the corresponding air quantity in this zone, wind direction according to what set.In step S42, when judgement needed the zone of air-conditioning to be not one, in step S44, judging needed whether the zone of air-conditioning is two, when the zone that needs air-conditioning is two, transfers to step S45.

In step S45, air quantity is set at the setting air quantity in the high zone of air-conditioning demand degree, as shown in figure 24, the configuration mode in two zones is identified as any of five patterns, in step S46 subsequently,, as shown in table 6ly control like that according to recognized patterns.

Table 6

At this, pattern 1 expression is the situation in the two adjacent zones in middle distance and double team indoor set front; The angle basically identical of pattern 2 expression and indoor set, context are the situation in adjacent two zones.In addition, mode 3 is represented the angle basically identical with indoor set, and context is the situation in two zones being separated by; Pattern 4 expression and indoor set apart from basically identical, the situation in two zones that angle is different; Two zones all different with distance, the angle of indoor set, are represented in two zones that pattern 5 expressions separate in other words.

The wind direction up and down of pattern 1～4 is fixed on the low zone of demand degree when heating, on the other hand, be fixed on the high zone of demand degree when refrigeration.In addition, control is the action of blade 12 up and down, after making first area stop stipulated time (fixed angle) of wind direction up and down in two zones (first and second zones) of pattern 5, turn to second area, after second area stops the stipulated time, turn to the first area again, so implement the action of this change wind direction repeatedly.And, the time of staying that each is regional, for example set respectively according to the distance of distance indoor set, be preferably apart from the distance of indoor set far more, the time of staying is long more.

In addition, with the left and right sides wind direction of pattern 1, be fixed on the central authorities in two adjacent zones; When being pattern 2 and 3, be fixed on by indoor set and observe, two zones are considered to the different roughly same direction of distance, and its left and right sides wind direction is fixed on the high zone of demand degree.In addition, about the left and right sides wind direction of pattern 4 with the pattern 5 that constitutes by two zones of separating, control the action of left and right sides blade in the mode the same with the control of blade 12 up and down, after the first area stops the stipulated time, wind direction is turned to second area, after second area stops the stipulated time, wind direction is turned to the first area, so carry out the action of this change wind direction repeatedly.And, the time of staying that each is regional, with respect to each regional relative position,, be preferably with indoor set front angulation greatly more according to indoor set for example according to setting respectively with indoor set front angulation, the time of staying is long more.

In addition, in step S44, when judgement needs the zone of air-conditioning (air conditioning) not to be two, in step S47, will need the zone more than three of air-conditioning (air conditioning) to be judged to be arbitrary pattern of normal mode or two kinds of patterns of special pattern according to its configuration.At this, special pattern is meant that into adjacent two zones in middle distance and double team indoor set front with for remote and be positioned at the zone in indoor set front amount to trizonal situation, the region representation more than three in addition is a normal mode.When the needs air conditioning area is three when above, air quantity is set at the setting air quantity in the highest zone of air-conditioning demand degree, in step S47, if be judged as the special pattern shown in Figure 21 (a) (central authorities' adjacency), in step S48, wind direction is set with the same mode of the pattern 1 of Figure 20.

On the other hand, in Mode S 47, when being judged to be when being not special pattern, in step S49, implement as Figure 25 (b) or the control of the normal mode (c), wind direction recently between the set angle and the set angle apart from the blade up and down 12 of indoor set most remote areas of the blade up and down 12 in zone, changes the angle of blade 12 up and down at the distance indoor set up and down.

In addition, left and right sides wind direction under the normal mode be with two end regions (in Figure 25 (b), be zone C and I, in Figure 25 (c), be zone C and H) in the set angle of left and right sides blade be set at left end angle and right-hand member angle, after the left end angle stops the stipulated time, wind direction is turned to territory, right-hand member lateral areas (conversion), after the right-hand member angle stops the stipulated time,, so carry out the action of this change wind direction repeatedly with the distolateral zone of wind direction port (conversion).And the running speed of the left and right sides blade during with conversion is set at the running speed that is slower than the left and right sides blade in above-mentioned pattern 4 and 5.In addition, the time of staying of left end angle or right-hand member angle is according to for example setting respectively with indoor set front angulation, is preferably with indoor set front angulation greatly more, and the time of staying is long more.

And, in step S43, S46, S48 or S49, implement to turn back to step S41 after each air-conditioning control.

In addition, under the situation that indoor set is configured as shown in Figure 14, in the time of near use first～the 5th sensor 26,28,30,32,34 judgement indoor sets have been set at the left side wall, also can only carry out the running control of left and right sides blade to the zone that is positioned at wall right side, left side.At this moment, the apparatus for detecting human body that is made of first～the 5th sensor 26,28,30,32,34 works as the automatic identification mechanism in position that is provided with of indoor set.

And, be preferably as the sensor that the automatic identification mechanism in position is set of indoor set and be provided with two at least, be example with the situation that in Fig. 4, is provided with optical axis first and second sensors 26,28 in the same plane, further describe.

When being provided with two sensors 26,28, will be from the output accumulation stipulated time (for example 3～4 hours) of each period T 1 of two sensors 26,28, compare by reaction result and the threshold value that will accumulate, two zones are divided into life zone and non-life zone, perhaps are divided into two life zones.And threshold value relatively can be for example above-mentioned second threshold value.

Near indoor set being located at the left side wall in the example of Figure 26 of (for example in the 1m), zone A is judged to be non-life zone, area B is judged to be the life zone, relative therewith, near indoor set being located at the right side wall when (for example in the 1m), the regional determination of indoor set frontal left is the life zone, is that non-life is regional with the regional determination of the positive right side of face of indoor set.In addition, when indoor set being arranged on wall when central authorities, the zone on indoor set frontal left and right side all is judged to be the life zone.

By the position that is provided with of so automatic identification indoor set, the control of can turning round to the wind direction controlling organization of the wind direction controlling organization of the above-below direction of air conditioner and left and right directions, thus only air conditioning is carried out in the zone of living.In the wall indoor unit of present embodiment, to controlling as the blade up and down of wind direction controlling organization and the running of left and right sides blade.

In addition, in the time of near indoor set being located at side walls,, just having human body detection sensor the curtain flase drop is behaved if the wind that is blown out by blow-off outlet 10 makes the curtain swing, make people place direction not have wind flow, perhaps unmanned place is mistaken for people's etc. problem on the contrary.

But, as shown in figure 26, whether the someone surveys among 26 couples of regional A of first sensor of the apparatus for detecting human body that is made of first and second sensors 26,28, and on the other hand, whether the someone surveys second sensor 28 with the non-overlapping separate areas B of regional A.Therefore, zone A and area B, with the center line between the optical axis of the optical axis of first sensor 26 and second sensor 28 be the boundary near and separate, when being arranged on this apparatus for detecting human body on the indoor set, about zone A and area B are divided into from the front of indoor set, result according to the detection reaction of the sensor in regional A that will not overlap each other at the appointed time and the area B is accumulated respectively can distinguish live zone and non-life zone reliably.At this,, when the detection reaction of sensor being arranged, wind direction control is not implemented in non-life zone in non-life zone by live zone and non-life zone are distinguished.In other words, at this moment, only wind direction control is implemented in the zone of living.So, when there is man-hour in the life zone, detect accidental reactions such as curtain swing immediately in non-life zone, also it is judged to be the reaction beyond the people, so that wind is not controlled wind direction to the mode that flows in non-life zone, just can avoid impairing the comfortableness in people's life zone thus.In addition, though the people under the situation of indoor disappearance, if detect accidental reaction such as curtain swing in non-life zone, also its is judged to be the reaction beyond the people, thereby can avoid erroneous judgement for the people is arranged.

In addition, the 3rd sensor 32 shown in Figure 4 is arranged on the apparatus for detecting human body, as shown in figure 27, can whether the someone surveys to zone C, this zone C is crossed in the center line both sides between the optical axis of the optical axis of first sensor 26 and second sensor 28, and C has man-hour when determinating area, and deducibility has the people by the zone C 2 that the indoor set top view is positioned at the right side, only append a sensor 32, the left side that just can judge the zone about leap still is whether the position on right side has the people.

Figure 28 represents and will be arranged on by the apparatus for detecting human body that six sensors constitute on the indoor set, and the position of human body critical region is divided into a plurality of zones, dispose two pairs from the indoor set top view adjacent and be divided into about the situation in two zones.

In example shown in Figure 28, zone A and B or region D and E represent adjacent and separated zone, the left and right sides, based on the result that will accumulate respectively at the detection reaction of the sensor among the regional A that does not overlap each other and B or region D and the E at the appointed time, can distinguish live zone and non-life zone more reliably.

In addition, indoor set is provided with timer, uses this timer can implement the unmanned probing Energy Saving Control and avoids forgetting to close power supply control, this unmanned probing Energy Saving Control and to avoid forgetting to close power supply control as described below.

At first, with reference to table 7 and Figure 29, the control during to heating is illustrated.

Table 7

Figure 29 represents an example of temperature drift, at this, to design temperature Tset be 28 ℃, situation when target temperature (critical value) is 20 ℃ describes.In addition, Δ T is the temperature difference of design temperature Tset and target temperature.

When utilize first～the 5th sensor 26,28,30,32,34 detect All Ranges A～I all nobody the time, timer begins counting, after utilizing timer to begin counting, if confirm nobody, just automatically design temperature Tset is reduced whole 2 ℃ (1/4 Δ T) at time point t1 (for example 10 minutes).Further, if confirm nobody, just further automatically design temperature Tset is reduced whole 2 ℃ (1/4 Δ T) at time point t2 (for example the counting beginning is back 30 minutes).Then, if unmanned at time point t3 (for example the counting beginning is back 1 hour) and time point t4 (for example the counting beginning is back 2 hours) affirmation equally, respectively design temperature Tset is reduced whole 2 ℃ (1/4 Δ T) automatically.

At time point t4, design temperature Tset is added up to 8 ℃ of reductions, equal 20 ℃ of target temperatures, therefore, up to time point t5 (for example beginning to count back 4 hours), design temperature Tset is maintained target temperature, if still confirm unmanned at time point t5 always, just stop the running of air conditioner, avoid forgetting to close the power supply of air conditioner.

In addition, during time point t1～time point t5,, just return to time point t1 design temperature Tset in the past when having detected man-hour.

In addition, as shown in table 7 like that, according to the temperature difference T of design temperature Tset and target temperature temperature drift amplitude (reduction temperature) is set.Temperature difference T is more little, and the temperature drift amplitude is more little.In addition, when design temperature Tset was lower than target temperature, the temperature of maintaining the statusquo when when time point t5 confirms nobody, just stops the running of air conditioner, and was the same with the example of Figure 29.

Below, with reference to table 8 and Figure 30, the temperature control during to refrigeration is illustrated.

Table 8

Figure 30 represents an example of temperature drift, at this, to design temperature Tset be 20 ℃, situation when target temperature (critical value) is 28 ℃ describes.In addition, Δ T is the temperature difference of design temperature Tset and target temperature.

When utilize first～the 5th sensor 26,28,30,32,34 detect All Ranges A～I all nobody the time, timer begins counting, begin counting by timer after, when when confirming nobody, just automatically design temperature Tset being increased whole 2 ℃ (1/4 Δ T) at time point t1 (for example 10 minutes).Further, when when nobody is confirmed in the back, further automatically design temperature Tset being increased whole 2 ℃ (1/4 Δ T) at time point t2 (for example the counting beginning is back 30 minutes).Then, when equally at time point t3 (for example counting beginning back 1 hour) and time point t4 (for example beginning to count back 2 hours) when confirming nobody, respectively with design temperature Tset whole 2 ℃ (1/4 Δ T) of increase automatically.

At time point t4, because of adding up to, design temperature Tset increases by 8 ℃, equal 28 ℃ of target temperatures, therefore, up to time point t5 (for example beginning to count back 4 hours), design temperature Tset is maintained target temperature, if still confirm unmanned at time point t5 always, just stop the running of air conditioner, avoid forgetting to close the power supply of air conditioner.

In addition, during time point t1～time point t5,, then return to time point t1 design temperature Tset in the past when having detected man-hour.

In addition, as shown in table 8 like that, according to the temperature difference T of design temperature Tset and target temperature temperature drift amplitude (increase temperature) is set.Temperature difference T is more little, and the temperature drift amplitude is more little.In addition, when design temperature Tset is higher than target temperature, keep the present stage temperature,, just stop the running of air conditioner when when time point t5 confirms nobody, the same with the example of Figure 30.

Figure 31 represents to reach by the air quantity (rotating speed) of control fan 8 and the performance that is arranged on the compressor in the off-premises station example of energy-saving operation.

That is, when increasing the air quantity of fan 8, the heat exchanger effectiveness of heat exchanger 6 just rises, the ability of refrigeration or heating increases when the frequency of compressor is identical, so, for indoor temperature being remained on the same settings temperature, can reduce the frequency of compressor, thereby reduce required consumption of electric power.In addition, when nobody the time, even increase the air quantity of fan 8, can not produce the discomfort that causes excessively by force because of air-flow yet or increase the comfortableness problem that causes because of the noise of fan 8.

Shown in Figure 31 (a), when utilize first～the 5th sensor 26,28,30,32,34 detect All Ranges A～I all nobody the time, timer begins counting, after timer begins counting, when at time point t1 (for example 10 minutes) when confirming nobody, shown in Figure 31 (b), the air quantity of fan 8 is increased, simultaneously, shown in Figure 31 (c), the frequency of compressor (for example beginning to count back 30 minutes) step evolution till the time point t2 is reduced.Though behind elapsed time point t1, the air quantity of fan 8 is kept certain (critical value), behind the elapsed time point t2, the frequency of compressor is kept certain (critical value), if but at time point t2, time point t3 (for example counting beginning back 1 hour), time point t4 (for example the counting beginning is back 2 hours), time point t5 (for example the counting beginning is back 4 hours) when continuing to confirm nobody, just, stop the running of air conditioner, avoid forgetting to close the power supply of air conditioner at time point t5.

In addition, during time point t1～t5,, just return to time point t1 setting air quantity and setpoint frequency in the past when having detected man-hour.

In addition, the example of above-mentioned Figure 29～Figure 31 all is in the routine running, at the appointed time nobody the time, carry out the example of province's electric operation of lacking than routine running consumption of electric power, when still being nobody afterwards at the appointed time, just stop the running of air conditioner, reach purpose of energy saving (" conventional running " is meant " running of user's indication ").

In addition, although it is long-term lasting unmanned, when the factor of human body detection sensor flase drop beyond the people such as curtain that might cause variations in temperature, under the unmanned state, also might always continue the normal mode running, such situation may take place because consider, so,, can guarantee to avoid forgetting to close power supply when shutting down through stipulated time t6 (for example 24 hours) time longer than time t5.In addition, before preferably being about to behind the long stipulated time t6 shuts down at elapsed time t5 or than time t5, on body or remote controller, utilize sound or LED lamp etc. to carry out vision or audio alarm, or on picture display text.Further, stop selected cell automatically if be provided with on remote controller etc., whether this stops selected cell automatically and is used for selecting shutting down automatically at elapsed time t5 or after than the long stipulated time t6 of time t5, just more can improve its ease of use.

So long as on indoor set, possess the air conditioner of at least one human body detection sensor, above-mentioned unmanned probing Energy Saving Control and prevent to forget to close power supply control and just can carry out the unmanned probing Energy Saving Control and prevent that forgetting to close power supply controls according to the output of a human body detection sensor.
