(inferring of activity)
Then,, after " the longitudinally Position Control of shutter " S82 of above narration, carry out " the inferring of activity " shown in Figure 10.Be somebody's turn to do " inferring of activity " according to the result of above-mentioned " the longitudinally Position Control of shutter ".
First, determine whether both sides (the region A on left side and the right side of the interior space
land region A
r) the middle human body H (S1001) existing as infrared source.As a result, as both sides (the region A judging on left side and right side
land region A
r) in while there is human body H (in figure for "Yes"), obtain the infrared ray sensor 110 from left side
lreactivity RA
lwith the infrared ray sensor 110 from right side
rreactivity RA
rmean value (=(RA
l+ RA
r)/2), judge whether the mean value that obtains exceedes predetermined threshold value th (for example 50%) (S1002).Then, result, in the time being judged as mean value and exceeding threshold value th (in figure for "Yes"), infers at region A
land region A
rthe activity of the human body of middle existence be " greatly " (S1003).On the other hand, in the time judging that mean value does not exceed predetermined threshold value th (being "No" in figure), judge activity as " in " degree (S1004).
Then, when judging at region A in above-mentioned judgement S1001
land region A
rin while there is not human body H (in figure for "No"), determine whether that in a region be region A
lor region A
rin there is human body (S1005).As a result, when judging at region A

rwhile not exceeding predetermined threshold value (in the drawings for "No"), infer activity for " little " (S1007).
And, when in above-mentioned judgement S1005, judge at reactivity RA
lor RA
rin while there is not human body (in the drawings for "No"), further judge whether in remaining region to be middle section A
min there is human body (S1008).As a result, when judging at central region A

min while there is not human body (in the drawings for "No") yet, establish activity for " nothing " (S1010).
At this, again return to Fig. 8, according to by the result that (S83) obtains of inferring of above-mentioned activity, for example, control the speed (wind speed), temperature (wind-warm syndrome) of the wind from indoor set to indoor conveying (S84).More particularly, in the time of the activity " greatly " promoting, increase the speed of the wind of carrying from indoor set 10 by wind direction board control part 160, revise the design temperature in wind-warm syndrome control part 180 downwards.And, at the activity of inferring while being middle, consider the situation while being large lower than activity, the amplitude of the increase of wind speed setting and the downward revision of design temperature.
Then, as shown in Figure 8, carry out far and near direction, what the human body H as infrared source on the depth direction of the interior space existed when indoor set 10 1 sides are watched infers action (Fig. 8: S85).In this " inferring of the human body existence of far and near direction ", as mentioned above, according to the position (angle) of the above-mentioned shutter 113 of the former configuration at lens polymerization body 112, about being divided into remote surveyed area (A
f), middle apart from surveyed area (A
i), this trizonal region (A of surveyed area closely
n), infer the existence as the human body H of infrared source.
(inferring of the human body existence in far and near (degree of depth) direction)
In Figure 11, represent the detailed content of this " inferring of the human body existence in far and near direction ".That is, first, about remote surveyed area (A
f), the surveyed area (A of middle distance
i), in-plant region (A
n) whole surveyed area (A
f+ A
i+ A
n), judge the infrared ray sensor 110 from left side
l, reactivity RA
lwith the infrared ray sensor 110 from right side
rreactivity RA
rin at least one party, i.e. reactivity RA
land/or RA
rwhether exceed predetermined threshold value th (for example 10%) (S1101).As a result, at reactivity RA
land/or RA
rwhile all not exceeding predetermined threshold value th (being "No" in the drawings), be made as the human body H not existing as infrared source indoor, again return to above-mentioned steps S1101, repeat above-mentioned judgement.
In addition, as mentioned above, about whole surveyed area (A
f+ A
i+ A
n), in the time of the existing of human body H, the infrared ray sensor 110 of above-mentioned pair of right and left
l, 110
ras shown in above-mentioned Fig. 6 (g), this shutter 113 moves to lower position, does not carry out blocking of incident infrared, becomes the state that makes whole infrared rays incide infrared ray dual sensor 111 via lens polymerization body 112.
Then, according to the result of above-mentioned judgement S1101, at reactivity RA
land/or RA
rwhile having exceeded predetermined threshold value th (being "Yes" in the drawings), be made as the human body H as infrared source in indoor existence, then, at remote surveyed area (A
f) in, similarly judge reactivity RA with above-mentioned
land/or RA
rwhether exceed predetermined threshold value th (for example 10%) (S1102).Now a pair of infrared ray sensor 110
l, 110
ras shown in above-mentioned Fig. 6 (a), this shutter 113 moves to uppermost position, blocks the surveyed area (A from middle distance
i) and in-plant surveyed area (A
n) infrared ray, become thus and only make from remote surveyed area (A
f) in the infrared ray of human body H that exists incide the state of infrared ray dual sensor 111.
According to the result of above-mentioned judgement S1102, at remote surveyed area (A
f) in, at reactivity RA
land/or RA
rwhile having exceeded predetermined threshold value th (being "Yes" in the drawings), infer at remote surveyed area (A
f) the middle human body H (S1103) existing as infrared source.On the other hand, when in above-mentioned judgement S1102, reactivity RA
land/or RA
rwhile not exceeding predetermined threshold value th (being "No" in the drawings), infer and in this remote surveyed area, do not have human body H, and, about the surveyed area (A of remote surveyed area and middle distance
f+ A
i), similarly judge reactivity RA with above-mentioned
land/or RA
rwhether exceed predetermined threshold value th (for example 10%) (S1104).
In the time of this judgement S1104, a pair of infrared ray sensor 110
l, 110
ras shown in above-mentioned Fig. 6 (d), this shutter 113 moves to centre position, blocks from in-plant surveyed area (A
n) infrared ray, become thus and only make from the surveyed area of middle distance and surveyed area (A at a distance
i+ A
f) in the infrared ray of human body H that exists incide the state in infrared ray dual sensor 111.
As a result, at middle distance and in-plant surveyed area (A
i+ A
n) in, at reactivity RA
land/or RA
rwhile exceeding predetermined threshold value th (being "Yes" in figure), the surveyed area (A inferring in middle distance
l) the middle human body H (S1105) existing as infrared source.And, at reactivity RA
land/or RA
rwhile not exceeding predetermined threshold value (being "No" in the drawings), but because infer in above-mentioned judgement S1101 and have human body H, so infer at remaining in-plant surveyed area (A
n) the middle human body H (S1106) existing as infrared source.
Then, again return to above-mentioned Fig. 8, the result of inferring (S85) existing according to the human body in above-mentioned far and near direction, via wind direction board control part 160, controls the angle (position) of horizontal shutter (S86).More particularly, in above-mentioned, inferring at remote surveyed area (A
f) in while existing as the human body H (above-mentioned Figure 11: S1103) of infrared source, set upward the angle (position) of horizontal shutter, so that air-supply arrives an indoor distant place.On the other hand, inferring at in-plant surveyed area (A
n) in while there is human body H (above-mentioned Figure 11: S1105), contrary to the above, set the angle (position) of horizontal shutter downwards, to only blow to the below of indoor set 10.Surveyed area (the A inferring in middle distance
i) in while there is human body (above-mentioned Figure 11: S1106), set the angle (position) of horizontal shutter to the angle (position) in the middle of above-mentioned cardinal principle.
As mentioned above, according to embodiments of the invention 1, provide a kind of air conditioner, it arranges at least two infrared ray sensors 110
l, 110
r, make a part for its surveyed area overlapped, then the movably shutter 113 that surveyed area is set as to concentric circles (circular arc) shape is set before each infrared ray sensor, thus by these two infrared ray sensors 110
l, 110
r, be divided into three region A by indoor in the horizontal direction
l, A
rand A
m, and in far and near (degree of depth) direction, for example, be separated into remote A
f, middle distance A
i, A closely
n, can more correctly infer the human body H as infrared source, can control more rightly thus the wind direction from air conditioner., can be with the wind of more appropriate wind direction and the more appropriate temperature of more appropriate wind speed impression on its position indoor people.
