In blow-off outlet 42, by upper bottom leaf 43 and about the wind direction of pendulum leaf 44 control above-below directions and left and right directions.The state of bottom leaf 43 closures in the expression in Fig. 3.

As shown in Figure 4, infrared ray sensor 3 is longitudinally arranged 8 photo detectors (not shown) row in metal can 1 inside.Be provided for the window (not shown) that makes infrared ray pass through the lens system of 8 photo detectors at the upper surface of metal can 1.The visible angle 2 of the luminous intensity distribution of each photo detector vertically is being 7 degree, laterally is being 8 degree.In addition, represented that the visible angle 2 of luminous intensity distribution of each photo detector is the situation of vertical 7 degree, horizontal 8 degree, but be not limited to vertical 7 degree, horizontal 8 degree.According to the visible angle 2 of the luminous intensity distribution of each photo detector, the number change of photo detector.For example, be certain as long as make the visible angle of vertical luminous intensity distribution of a photo detector and the long-pending of quantity of photo detector.

In the example of Fig. 4, because photo detector is 8, the vertical visible angle of luminous intensity distribution is 7 degree, so the long-pending of the visible angle of vertical luminous intensity distribution of a photo detector and the quantity of photo detector is 56 (8 (individual) * 7 (degree)).Therefore, for example also can be that photo detector is 7, the vertical visible angle of luminous intensity distribution is 8 degree.In addition, also can be that photo detector is 14, the vertical visible angle of luminous intensity distribution is 4 degree.

Fig. 5 sees near the infrared ray sensor 3 stereogram from inboard (from the inside of air regulator 100).As shown in Figure 5, infrared ray sensor 3 (can't see at Fig. 5) is accommodated in the basket 5.In addition, the stepper motor 6 that drives infrared ray sensor 3 is set above basket 5.Be fixed in the front lower of air regulator 100 by handle and the installation portion 7 of basket 5 one, infrared ray sensor 3 is installed on the air regulator 100.Be installed at infrared ray sensor 3 under the state of air regulator 100, stepper motor 6 is vertical with basket 5.In addition, in the inside of basket 5, infrared ray sensor 3 is installed downwards with the angle of about 24.5 degree in the angle of depression.

Infrared ray sensor 3 drive to rotate predetermined angular scope (following such rotating drive is shown as " removable ") by stepper motor 6 at left and right directions, be movable to left end end (c) from right-hand member end (a) via central portion (b) as shown in Figure 6, reversally removable round about when coming left end end (c).Repeatedly should action.Infrared ray sensor 3 about the temperature detection object range in scanning room, the simultaneously temperature of detected temperatures detected object.

About this is said, refer to from infrared ray sensor 3 sides see about.

Then, the method for the thermographic image data on the wall in the room obtained with infrared ray sensor 3 or floor is set forth.In addition, the control of infrared ray sensor 3 grades by the regulation operation program microcomputer carry out.Will the regulation operation program microcomputer be defined as " control part ".In the following description, omit the record of being carried out each control by control part (with the operation program of regulation microcomputer).

In the situation of the thermographic image data on the wall of obtaining the room or floor, make infrared ray sensor 3 removable at left and right directions with stepper motor 6, per 1.6 degree of the movable angle of stepper motor 6 (the rotating drive angle of infrared ray sensor 3) make infrared ray sensor 3 stop the stipulated time (0.1～0.2 second) in each position.

After infrared ray sensor 3 stops, waiting for the stipulated time (than the time of 0.1～0.2 second weak point), be taken into the testing result (thermographic image data) of 8 photo detectors of infrared ray sensor 3.

After the testing result that is taken into infrared ray sensor 3 finishes, stop after driving again stepper motor 6 (movable angle 1.6 degree), be taken into the testing result (thermographic image data) of 8 photo detectors of infrared ray sensor 3 by same action.

Repeatedly carry out above-mentioned action, the thermographic image data in take the testing result of the infrared ray sensor 3 at left and right directions 94 places as the basic calculation detection zone.

Owing to make infrared ray sensor 3 stop to be taken into thermographic image data by per 1.6 degree of the movable angle of stepper motor 6 at 94 places, so the movable range of the left and right directions of infrared ray sensor 3 (at the angular range of left and right directions rotating drive) is about 150.4 degree.

Fig. 7 is illustrated in the visible angle of vertical luminous intensity distribution in the vertical section of the infrared ray sensor 3 that air regulator 100 is installed under the state of the height of the floor 1800mm in room, 8 photo detectors become row at longitudinal arrangement.

The visible angle of vertical luminous intensity distribution of a photo detector 7 ° of the angles shown in Fig. 7.

In addition, 37.5 ° of the angles of Fig. 7 be represent not enter infrared ray sensor 3 vertical area of visual field the zone, apart from the angle of the wall that air regulator 100 is installed.If the angle of depression of infrared ray sensor 3 is 0 °, then this angle is 90 °-4 (quantity of photo detector below horizontal) * 7 ° (visible angle of vertical luminous intensity distribution of a photo detector)=62 °.Because the angle of depression of the infrared ray sensor of present embodiment 3 is 24.5 °, so be 62 °-24.5 °=37.5 °.

Fig. 8 represent will be in the room that is equivalent to 8 straw mats housewife 12 have living scene of child 13 in arms so that the result that infrared ray sensor 3 calculates for the basis, as thermographic image data in the removable testing result that obtains simultaneously of left and right directions.

Fig. 8 is to be season winter and the thermographic image data that obtains on the date of weather the moon.Therefore, the temperature of window 14 is low is 10～15 ℃.Housewife 12 and child's 13 temperature is the highest.Particularly the temperature of housewife 12 and child's 13 the upper part of the body is 26～30 ℃.Like this, by making infrared ray sensor 3 removable at left and right directions, for example can obtain the temperature information of room each several part.

The resume of the floor that then, produces to according to the ability band of air regulator 100, operation of air conditioner the time and temperature difference (temperature the is uneven) information of wall and human detection position judge comprehensively, determine that the room shape detection means (space identity detection) of room shape records and narrates.

By the thermographic image data that is obtained by infrared ray sensor 3, obtain the floor size in the conditioned zone that just carries out air conditioning, obtain the wall position in the conditioned zone on the heat picture.

Because heat picture understand floor, wall (so-called wall refer to the face wall seen from air regulator 100 and about wall) the zone, so can obtain each wall mean temperature, can obtain wall surface temperature, the high-precision sendible temperature of having considered the relative human body that detects at heat picture.

Ask the means of calculating the floor size in thermographic image data, by merging three kinds of information that represent below, can carry out the detection of high-precision floor size and detect room shape.

(1) the shape limits value of being obtained by the installation site button settings of the ability band of air regulator 100 and remote controller and the room shape of initial setting value.

The room shape that the temperature inequality of the floor that (2) produces from the running of air regulator 100 and wall is obtained.

(3) room shape of being obtained by human detection position resume.

Air regulator 100 is divided into corresponding ability band take the size in the room that carries out air conditioning as benchmark.Straw mat benchmark when Fig. 9 is expression by the cooling operation of the ability band of air regulator 100 regulation and the figure of size (area).For example, be in the situation of 2.2kw in the ability of air regulator 100, the straw mat benchmark of the air conditioning size during cooling operation is 6～9 straw mats.The size (area) of 6 straw mat to 9 straw mats is 10～15m ²

Figure 10 is the figure by the size (area) of the floor of the maximum area of the size (area) of using the described every kind of ability of Fig. 9, every kind of ability of regulation.Be in the situation of 2.2kw in ability, the maximum area of the size of Fig. 9 (area) is 15m ²By obtaining 15m ²Square root, vertical-horizontal proportion is made as 1: 1 o'clock distance in length and breadth respectively for 3.9m.Be fixed as 15m by maximum area ², can in 1: 2～2: 1 scope, change the distance in length and breadth in the situation of vertical-horizontal proportion, set in length and breadth ultimate range and minimum range.

The figure of the room shape limits value in length and breadth of expression ability 2.2kw in Figure 11.Maximum area 15m by every kind of ability ²Square root to establish vertical-horizontal proportion be that each distance in length and breadth in 1: 1 the situation is 3.9m.By maximum area is fixed as 15m ², make vertical-horizontal proportion distance in length and breadth in the changeable situation in 1: 2～2: 1 scope, set ultimate range in length and breadth.Be in 1: 2 the situation, to be vertical 2.7m at vertical-horizontal proportion: horizontal 5.5m.Under vertical-horizontal proportion is 2: 1 situation, be vertical 5.5m equally: horizontal 2.7m.

Figure 12 represents the Horizontal Distance condition obtained by the ability band of air regulator 100.The value of the initial value of Figure 12 is obtained according to the square root of the middle area of the corresponding area of every kind of ability.For example ability is that the adaptation area of 2.2kw is 10～15m ², middle area is 12m ²By 12m ²Square root obtain initial value 3.5m.Below ask calculation for the calculating of the Horizontal Distance of the initial value of every kind of ability band from same viewpoint.It is such that simultaneously minimum of a value (m), maximum (m) are pressed the calculating of Figure 10.

The initial value of the room shape of therefore, being obtained by every kind of ability of air regulator 100 the initial value of Figure 12 (m) as in length and breadth distance.But, the initial point of the setting position of air regulator 100 is changed.

The condition when central authorities when Figure 13 represents that ability is 2.2kw install.As shown in figure 13, the transfer of initial value from the initial point of intermediate location as air regulator 100.The initial point of air regulator 100 becomes the in length and breadth position relationship of the central portion in the room of 3.5m (apart from horizontal side 1.8m).

The situation of (from the user) when the left comer when Figure 14 is illustrated in ability and is 2.2kw is installed.In the situation when being installed on left comer, arrive about the distance of the wall that approaches be made as the distance of initial point (the horizontal wide central point) 0.6m apart from air regulator 100.

Therefore, (1) the shape limits value of obtaining according to the installation site button settings of the ability band of air regulator 100 and remote controller and the room shape of initial setting value, determine the installation site of air regulator 100 by the condition ground, installation site that from the floor size that the ability band of air regulator 100 is set, attaches remote controller in the above condition, thereby can obtain in the thermographic image data that is obtained by infrared ray sensor 3 boundary line of floor and wall.

The floor of installation site button settings on the thermographic image data when the central authorities and the position relationship of wall of the ability of expression air regulator 100 when being 2.2kw, remote controller in Figure 15.Watch from infrared ray sensor 3 sides, can find out the situation that is showing left wall 16, face wall 19, right wall 17 and floor 18 in thermographic image data.Ability during initial setting be 2.2kw the floor geomery as shown in Figure 13.Below, left wall 16, face wall 19, right wall 17 are referred to as wall.

Then, (2) describe the calculating means of the room shape obtained by the temperature inequality of the floor that produces in air regulator 100 running and wall.Expression is by the calculation process of the uneven room shape that forms of temperature in Figure 16.Be characterised in that, infrared ray sensor drive division 51 by the infrared ray sensor 3 that drives above-mentioned record, on the heat picture of the vertical 8* horizontal stroke 94 that generates as thermographic image data with infrared view obtaining section 52, utilize benchmark wall position calculation section 54, the uneven scope that detects of temperature on the thermographic image data is carried out in restriction.

Below, when the air regulator ability in Figure 15 is 2.2KW under the condition of remote controller mounting condition when central authorities, the function of benchmark wall position calculation section 54 is described.

Figure 17 is illustrated in the boundary line 60 between the pixel up and down on the border that becomes wall and floor 18 on the thermographic image data of Figure 15.Pixel in the boundary line more than 60 becomes the luminous intensity distribution pixel that detects wall surface temperature, and the pixel of 60 downsides becomes the luminous intensity distribution pixel that detects the floor temperature in the boundary line.

In addition, in Figure 18, be characterised in that there is 1 pixel the position of the boundary line 60 of relatively being set by Figure 17 and up between 3 pixels of the total that 2 pixels are arranged, detects the temperature that produces between pixel up and down in lower direction.

Being characterised in that, is not to seek temperature difference between all pixels of full thermographic image data, but centered by on the boundary line 60 of wall and floor the poor temperature that produces in the boundary line 60 of wall and floor that detects of detected temperatures.

Be characterised in that to have simultaneously the minimizing (cripetura of calculating treatmenting time and load reduction) and the error detection processing (disturb and judge processing (ノ イ ズ デ バ Application ス processing)) that are detected the unnecessary software computing that forms by both full-pixel.

Below, be characterised in that with respect to temperature inequality Boundary Detection 53 (Figure 16) of the section inter-pixel areas of above-mentioned record, that detect by the uneven border that forms of temperature, can utilize any one means detection boundaries line 60 in the following means:

(a) judging means that the absolute value that obtains according to the thermographic image data from floor temperature and wall surface temperature forms, (b) judging means of the maximum formation of the up and down slope of the depth direction of temperature difference between pixel (1 subdifferential) of basis in surveyed area, (c) judging means of the maximum formation of the up and down slope of the slope of the depth direction of temperature difference between pixel (2 subdifferential) of basis in surveyed area.

Figure 19 is characterised in that, in above-mentioned image detection zone, by the uneven Boundary Detection of the temperature section 53 on the uneven border of detected temperatures, will surpass the image of threshold value or carry out mark above the peaked image of slope with black.In addition, do not implement mark for the threshold value or the peaked position that do not surpass the uneven border of above-mentioned detected temperatures.

Figure 20 represents to detect the result by the uneven boundary line that forms of temperature.With the condition of the boundary line line between pixel with following situation as condition, namely, in the uneven Boundary Detection of temperature section 53, for the bottom of the pixel that surpasses threshold value or peaked density bullet, also have surveyed area surpass up and down threshold value or peaked row between pixel, carry out line with the reference position of in Figure 17, having been undertaken between the pixel of initial setting by benchmark wall position calculation section 54.

In addition, on thermographic image data, the coordinate points of each element that is connected to the bottom, boundary line (X, Y) by floor coordinate converting section 55 (Figure 16) conversion as the floor coordinate points, project on the floor 18, become Figure 21.Can be understood as the result of element coordinate of the bottom of linking boundary line 60 of projection 94 row amounts.

The zone of the object pixel that near the temperature difference face wall 19 positions under the initial setting condition when Figure 22 represents ability 2.2kw, the central mounting condition of remote controller detects.

At first, in floor 18 projections among Figure 21 of boundary line element coordinate of each thermographic image data, obtain the mean value of the distribution element coordinate points that detects near each element face wall shown in Figure 22 19 positions, obtain the wall position of face wall 19 and floor 18, become Figure 23.

With the viewpoint same with face wall boundary line line means, draw the boundary line by the mean value corresponding to the distribution element coordinate points of each element of right wall 17 and left wall 16.In addition, with about the zone that is attached to together of left wall boundary line 20, right wall boundary line 21 and face wall boundary line 22 become the floor zone.

In addition, as by the uneven higher means with wooden partition boundary line, ground line of precision that form that detect of temperature, also have by the mean value of the element coordinate Y in the zone of obtaining positive boundary line at Figure 22 and standard deviation being asked calculation, only being become element object means of calculating mean value again below the threshold value with the σ value.

When calculating wall boundary line, the left and right sides, also can use mean value and the standard deviation of each element coordinate X equally.

In addition, calculate another means of wall boundary line, the left and right sides, also can be relatively by the face wall boundary line calculate the Y coordinate that obtain, namely apart from the distance of the wall of air regulator 100 installation sides, use is distributed in the mean value of X coordinate of each element of the zone line 1/3～2/3 of distance between the Y coordinate, obtains the boundary line between the wall of the left and right sides.Under any circumstance all no problem.

The installation site of the air regulator 100 of obtaining with the positive left and right sides wall position calculation section 56 by above-mentioned means as the distance Y apart from face wall 19 of initial point, apart from the distance X _ left of left wall 16, apart from the distance X _ rigbt of right wall 17, accumulate section 57 and add up apart from summation as each by detecting resume, and detect counting as distance number of times add up, obtain the distance that averages out with the division of the number of the summation of detection distance and counting.Obtain for left and right sides wall also available same means.

In addition, so long as the situation of Duo than threshold number by the detection number of times that detects resume and accumulate section's 57 countings is just effective by the result of determination of the uneven room shape that forms of temperature.

Then, (3) describe the calculating of the room shape obtained by human detection position resume.Represent flow process by human detection position resume calculated room shape at Figure 24.Be characterised in that, body detecting part 61, for the thermographic image data according to the vertical 8* horizontal stroke 94 that the output of the infrared ray sensor drive division 51 that drives infrared ray sensor 3 is generated as thermographic image data by infrared view obtaining section 52, the residual quantity of the thermographic image data by getting itself and dead ahead is judged the position of human body.

Human body has or not and the body detecting part 61 of position of human body has following characteristics, namely, when obtaining the residual quantity of thermographic image data, but detect the threshold value A of residual quantity and the threshold value B that the slightly low underfooting part of surface temperature detects residual quantity near having respectively can be to the surface temperature of human body higher head.

Figure 25 carries out the background image in dead ahead and the residual quantity of the thermographic image data that human body exists is measured, and judges the detection of human body with threshold value A and threshold value B.The residual quantity zone of judging the thermographic image data that surpasses threshold value A is near the human body head, obtains the heat picture residual quantity zone that surpasses threshold value B with the zone adjacency of being obtained by threshold value A.At this moment, the residual quantity zone of being obtained by threshold value B be take with the residual quantity obtained by threshold value A zone in abutting connection with as prerequisite.Namely be only be that the residual quantity zone that surpasses threshold value B can not judge to be human body.The relation table of the residual quantity threshold value between thermographic image data is shown threshold value A＞threshold value B.

The zone from the head of human body to the underfooting can be detected in the zone of the human body of being obtained by these means, utilizes heat picture coordinate X, the Y of middle body of residual quantity zone lowest end at the position, underfooting of expression human body, as position of human body coordinate (X, Y).

Be characterised in that, by means of floor coordinate converting section 55, the position of human body resume are accumulated section 62 and are accumulated the position of human body resume, this floor coordinate converting section 55 the underfooting position coordinates (X, Y) of the human body of being obtained by the residual quantity of thermographic image data such as conversion Figure 21 of following temperature is uneven explanation when detecting as the floor coordinate points.

Figure 26 represents as the human detection position of obtaining according to the thermographic image data residual quantity has been carried out people's position coordinates (X, Y) point of coordinate transform, carried out the situation of counting accumulative total in each X-axis, Y-axis by floor coordinate converting section 55.As shown in figure 26, accumulate in the section 62 at the position of human body resume, laterally the minimal decomposition of X coordinate and depth Y coordinate guarantees to form the zone of every 0.3m, to guarantee the applicable counting of the position coordinates (X, Y) that produces in the zone at 0.3m interval when detecting the people position at every axle.

By accumulating the human detection position record information of section 62 from these position of human body resume, can obtain floor 18, wall (left wall 16, right wall 17, face wall 19) as room shape by wall position judgment section 58.

Figure 27 represents the result of determination of the room shape that formed by the position of human body resume.Be characterised in that, utilize with respect to the maximum of accumulating at transverse direction X coordinate and depth Y coordinate and accumulate the scope that numerical value is the zone 10% or more, judge that floor is regional.

Then, such example is described, namely, to infer room shape be rectangle (square) or L glyph shape according to the data of accumulating of human detection position resume, uneven by the floor 18 and near the temperature the wall (left wall 16, right wall 17, face wall 19) that detect L font room shape, calculate high-precision room shape.

Figure 28 represents the result of human detection position resume in the living room of L font room shape.Laterally the minimal decomposition of X coordinate and depth Y coordinate guarantees to form the zone of every 0.3m, to the applicable counting of position coordinates (X, Y) that produces during whenever human detection in the zone that guarantees the 0.3m interval at every axle.

Certainly, because human body is mobile in the room shape of L word, so the number of counting that is accumulated in the floor zone (Y coordinate) of the floor zone (X coordinate) of left and right directions and depth direction becomes each depth zone (area) the proportional form with each X, Y coordinate.

To judging that by the data of accumulating of human detection position resume room shape is rectangle (square) or describes for the means of L glyph shape.

Figure 29 represents the number of the counting that is accumulated in floor zone (X coordinate) in the horizontal X coordinate.Be characterised in that the numerical value of accumulating of the relative maximum of accumulating of threshold value A is more than 10%, judge the distance (width) of floor directions X.

In addition, as shown in figure 30, be characterised in that, floor zone (X coordinate) equalization of obtaining at Figure 29 is divided into regional ABC three parts, obtain accumulating numerical value and being present in which zone of the maximum accumulated, obtain simultaneously each maximum and the minimum of a value in each zone.

The numerical value of accumulating of the maximum of accumulating is present in regional C (perhaps regional A), maximum in the C of zone and the difference of minimum of a value are in Δ α, the maximum of zone C is accumulated maximum in numerical value and the regional A, and to accumulate several differences be Δ β when above, and judgement is L font room shape.

Each maximum and the poor Δ α of minimum of a value that obtains each zone is for being inferred of room shape and disturbed and judge and process by the data of accumulating of human detection position resume.As shown in figure 31, also have such means, that is, existing the maximum accumulate data to accumulate in several situations in regional C, is that the number of the counting more than 90% has γ bar (by the number in the zone of every 0.3m decomposition) to judge in the zone according to the relatively maximum number of accumulating.After regional C implemented above-mentioned computing, by carrying out the calculating same with regional A, judgement was L font room shape (Figure 32).

Be in the situation of L font room shape by above-mentioned judgement, as shown in figure 33, obtaining the relatively maximum number of accumulating is position more than 50%.This explanation is illustrated with horizontal X coordinate, but for accumulating data too in the Y coordinate of depth direction.

Be characterised in that, judge that the number of accumulating of maximum in the floor zone of Y coordinate of relatively horizontal X coordinate and depth direction is that threshold value B more than 50% is the floor of L font room shape and the boundary point of wall as the coordinate points on border.

Figure 34 represents the floor region shape of the L font room shape obtained by the boundary point of the floor of the L font room shape of obtaining at Figure 33 and wall with by the floor zone of the X coordinate more than the threshold value A, Y coordinate.

Be characterised in that, the benchmark wall position calculation section 54 that arrives the uneven room shape algorithm of temperature at the floor shape result feedback of the above-mentioned L glyph shape of obtaining, calculate again the uneven scope that detects of the temperature of carrying out on the thermographic image data.

Then, the method that will ask three information merging of calculating room shape is described.But, the floor shape result feedback of L glyph shape to the benchmark wall position calculation section 54 of the uneven room shape algorithm of temperature, calculate the uneven such processing of scope that detects of the temperature of carrying out on the thermographic image data again, is removed at this.

Figure 35 represents to merge the flow process of three information.(2) room shape of being obtained by the temperature inequality of the floor 18 that in air regulator 100 runnings, produces and wall, so long as accumulate the situation that detection number of times that section 57 counts Duo than threshold number by the uneven Boundary Detection of temperature section 53 detecting resume, the result of determination of the room shape that is formed by the temperature inequality in the uneven availability deciding of temperature section 64 is exactly effective.

Equally, (3) room shape of obtaining from human detection position resume, accumulate the room shape that section 62 obtains from the position of human body resume, also be so long as accumulate situation that human detection position resume number of times that section 62 accumulates the position of human body resume Duos than threshold number at the position of human body resume, be on the basis of effectively such precondition in the result of determination of the room shape that position of human body availability deciding section 63 is formed by human detection position resume, judged by following condition by wall position judgment section 58.

One, in (2) and (3) all in the invalid situation, becomes the room shape of the initial setting value of obtaining according to the installation site button settings of the ability band of the air regulator 100 that is formed by (1) and remote controller.

Two, in (2) effectively and in (3) invalid situation, the Output rusults that will be formed by (2) is as room shape.At this, the room shape in (2) is not in the situation in the length on the limit of being determined by Figure 12 of (1), perhaps is not in the situation in the area, can be flexible in this scope.At this, in the situation flexible by area, revise with the distance that arrives face wall 19.

Concrete modification method is described.In Figure 36 the expression ability be 2.8kw, remote controller installation site condition during for central authorities by the uneven result who detects the room shape that forms of temperature.By Figure 12, the minimum of a value of the length on the limit in length and breadth when the ability of air regulator 100 is 2.8kw is 3.1 m, and maximum is 6.2m.For this reason, by remote controller central authorities mounting condition, the limiting distance of the distance X _ left of the wall in the distance X _ right of the wall on arrival right side and arrival left side is defined as half of Figure 12.For this reason, the distance of the right wall minimum/left wall minimum shown in the figure is 1.5m, and the distance of right wall maximum/left wall maximum is 3.1m.As shown in figure 36 such by the uneven room shape that forms of temperature in for the situation of distance above the state of the distance of left wall maximum that arrives left wall 16, as shown in figure 37, narrows down to the position of left wall maximum.

Equally, in the situation between right wall minimum and the right wall maximum, keep original position relationship in the distance that arrives as shown in figure 36 right wall.As shown in figure 37, dwindle into left wall maximum after, obtain the area of room shape, confirm that whether areal extent when the ability shown in Figure 12 is 2.8kw is at 13～19m ²OK range in.

Suppose that the room shape area at revised Figure 37 arrives greatly Maximum Area 19m ²In the above situation, as shown in figure 38, by being reduced to, the distance of face wall 19 becomes maximum area 19m ²Adjust.

Same with the situation shown in Figure 39, in the situation of the not enough left wall minimum of distance that arrives left wall 16, enlarge the zone that arrives left wall minimum.

As shown in figure 40, by calculate revised room shape area judge whether be in proper area in thereafter.

Three, invalid and (3) effectively in situation in (2), also the Output rusults that is formed by (3) as room shape.With in above-mentioned (2) effectively and (3) invalid situation two same, revise so that the length on the limit that is suitable for being determined by (1), the restriction of area.

Four, in (2), (3) all effectively in the situation, take by the uneven room shape that forms of the temperature of (2) as benchmark, the room shape that is formed by the human detection position resume of (3) thus, in the situation of the narrow face of the distance that exist to arrive wall, be modified to width with maximum 0.5m and make the direction of being dwindled by the output of the uneven room shape that forms of temperature of (2).

On the contrary, do not revise in the wide situation in (3).In addition, also can revise for revised room shape, to be fit to by the length on (1) definite limit, the restriction of area.

According to above-mentioned merging condition, that works as shown in Figure 41 obtains as distance Y coordinate Y_front, the X coordinate X_right of right wall 17, the X coordinate X_left of left wall 16 each wall distance between the surface, that arrive face wall 19.

Then, the calculating of wooden partition radiation temperature describes over the ground.Expression is the contrary thermographic image data that projects to of each coordinate points on the floor boundary line of obtaining according to separately distance between a face wall 19 of being tried to achieve by above-mentioned merging condition, left and right sides wall (left wall 16, right wall 17) in Figure 42.

On the thermographic image data of Figure 42, be appreciated that the situation in the zone of the zone that is divided into floor 18, face wall 19, left wall 16, right wall 17.

At first, about the calculating of wall surface temperature, the mean value of the temperature data of being obtained by the thermographic image data in each wall zone of trying to achieve in thermographic image data as wall temperature.

As shown in figure 43, the zone that impales each wall zone with thick line becomes each wall zone separately.

Then, the temperature province of floor 18 described.Floor zone on the thermographic image data for example is divided into five parts, is divided into three parts at depth direction at left and right directions, be subdivided into and amount to 15 part cut zone.In addition, the quantity in the zone of cutting apart is not limited to this, can be arbitrarily.

Example shown in Figure 44 is that the territory, nearby lateral areas to floor 18 is divided into the zone (A1, A2, A3, A4, A5) that left and right directions five parts are cut apart.

Equally in Figure 45, the zone (B1, B2, B3) that three parts were cut apart before and after the territory, depth lateral areas of floor was divided into.Be characterised in that, in each of any one zone, floor area coincidence all around.Therefore, on thermographic image data, generate face wall 19, left wall 16, the temperature of right wall 17 and the temperature data that is divided into the floor temperature of 15 parts.The temperature conduct mean temperature separately in each floor zone of cutting apart.Take each temperature information of zoning on this thermographic image data as the basis, can obtain the radiation temperature of each human body in the captured residential area of thermographic image data.

Can consider the calculating of radiation temperature of the impact of the wall surface temperature of floor temperature, each wall in the place of human detection and each wall distance between the surface.

Figure 46 represents an example of the radiation temperature obtained by above-mentioned calculating formula.By on thermographic image data, by the condition that testee A and testee B are detected, calculate radiation temperature in the living space of thermographic image data photographs.Face wall temperature T _ front:23 ℃, T_left:15 ℃, T_right:23 ℃, f.ave=20 ℃ of the floor temperature T of testee A, f.ave=20 ℃ of the floor temperature T of testee B, the correction factor on the radiation temperature formula all calculates with 1, its result, can obtain testee A radiation temperature Tcalc=18 ℃, the radiation temperature Tcalc=23 of testee B ℃.

Only by the temperature computation radiation temperature of floor 18, still, can consider radiation temperature from required wall surface temperature by the identification room shape in the prior art, can obtain the radiation temperature that human body is felt by whole health body.

The floor that produces based on by operation of air conditioner described above time the and the temperature difference of wall (temperature is uneven) information, the resume of human detection position, the ability band of air regulator, " the space identity detection " of room shape determined in comprehensive judgement, and " without the automatic high-power running of remote controller " in part utilization " space identity detection " described.

So-called " without the automatic high-power running of remote controller " refers to just can automatically carry out high-power running without remote controller.

" without the automatic high-power running of remote controller " for example is that infrared ray sensor 3 detects the testee's (being also referred to as people, human body, user, occupant) who stood before air regulator 100 at once, blows out the pattern of hot blast or cold wind to the testee.When high-power running, carry out air-flow control and the fan speed of the best and the control of compressor frequency towards testee standing place direction.In addition, be characterised in that not in the situation before the air regulator 100, have the function of transferring at once common operation mode the testee.

The advantage of " without the automatic high-power running of remote controller " is such as shown below.

(1) because the testee need not the remote controller for high-power running, so do not bother fully.

(2) owing to can accurately judge the position of testee's face, thus can take above the waist or head blow out hot blast, cold wind as target.

(3) if because the testee left, then transfer at once common operation mode (making being scanned into of infrared ray sensor 3 become common scanning take room integral body as object), so efficient is high before air regulator 100.

Evaluation algorithm is detected in above-mentioned boundary line in the heat picture adquisitiones that is undertaken by infrared ray sensor 3, by stepper motor 6 left and right directions in accordance with regulations the angular range rotating drive arrange the infrared ray sensor 3 of 8 photo detectors on the inner vertical row ground of metal can 1, about detect the temperature in room or the temperature of human body in the scanning.In addition, be characterised in that, utilize by the obtaining of the heat picture of a picture amount that obtains the predetermined angular scope, obtain the residual quantity with the heat picture of last time obtaining, can implement thus the control of human detection and Boundary Detection function and judge.

But, have the time-related problem that needs tens of seconds time for the thermographic image data 1 picture amount that obtains the predetermined angular scope.That is, real-time performance is poor.

The thermographic image data at three positions when Figure 47 represents that infrared ray sensor 3 scans from left to right.Figure 47 (a) expression obtains the state of the heat picture of five vertical pixels (element 8～4) of 32 row from left side to the.Up-to-date heat picture 5 row amounts in this case, utilization obtain whole heat pictures 27～31 row 5 row amounts heat picture (being impaled by thick line) and become up-to-date heat picture 5 row amounts.

Equally, Figure 47 (b) expression infrared ray sensor 3 proceed from left to right scanning, obtain the state of the heat picture of six vertical pixels (element 8～3) of 54 row from left side to the.Up-to-date heat picture 5 row amounts in this case, utilization obtain whole heat pictures 49～53 row 5 row amounts heat picture (being impaled by thick line) and become up-to-date heat picture 5 row amounts.

Equally, Figure 47 (c) expression infrared ray sensor 3 proceed from left to right scanning, obtain the state of the heat picture of eight vertical pixels (element 8～1) of 86 row from left side to the.Up-to-date heat picture 5 row amounts in this case, utilization obtain whole heat pictures 82～86 row 5 row amounts heat picture (being impaled by thick line) and become up-to-date heat picture 5 row amounts.

Like this, be characterised in that, for measuring station immediately stands in testee before the air regulator 100, utilize as from the absolute value information up-to-date heat picture 5 row amounts, that amount to 8*5=40 amount of pixels (vertical 8* horizontal stroke 5) of left and right directions at the infrared ray sensor of predetermined angular scope interscan, implement at once the judgement that air regulator 100 has or not the testee who stands before.

In addition, as shown in figure 48, (apart from air regulator 100 the 1.5m degree is arranged) in the time of before the testee stand in air regulator 100, as the relation in the testee's who obtains with infrared ray sensor 3 heat picture zone (transverse width), must be testee's heat picture transverse width zone＞5 row.

Owing to make infrared ray sensor 3 stop to obtain thermographic image data by per 1.6 degree of the movable angle of stepper motor 6 at 94 places, so 5 row are equivalent to movable angle 8 degree.Because the imagination testee stand in the state that leaves the position of 1.5m degree from air regulator 100, so rotational angle 8 degree are equivalent to about 20cm in the position of leaving 1.5m.Because testee's width is obviously large than 20cm, so it physically is impossible that testee's heat picture transverse width zone＜5 are listed in.

Be characterised in that the infrared ray sensor 3 of 8 elements itself has the inside thermistor temp Tamb information (inner thermistor temp Tamb becomes the cold junction fiducial temperature) as self fiducial temperature when asking the temperature of calculating the detected object thing.

Below, have or not evaluation algorithm to describe to the absolute value human body that is formed by 8 element *, 5 row=40 hot pixels.As shown in figure 49, be envisioned for the state that the testee stand in (about 1.5m) before the air regulator 100.

Obtain 1 row amount at infrared ray sensor 3 and implement afterwards in this specification of each absolute value judgement, the threshold value δ that the absolute value that human body has or not is judged is the inside thermistor temp Tamb+ Δ Ta of infrared ray sensor 3.

Testee's's (human body) temperature is about 36 ℃ of body temperature, but when wearing clothes, and the impact of environment temperature is also arranged and becomes about 30 ℃.The surface temperature of clothes is about 30 ℃ in other words.

For example, air regulator 100 heat that the room conditioning temperature stabilization is in 22 ℃ situation in the running, the internal temperature of infrared ray sensor 3 also is the Tamb=22 degree.As an example, be characterised in that in Δ Ta=4 ℃ situation, mean that the absolute value judgment threshold δ of heat picture becomes 26 ℃ by Ta=22 ℃+4 ℃ of Tamb+ Δs, Δ Ta can change according to the operating condition of air regulator 100.

The indicator of operating condition illustrates the transformation of following two states:

(1) air regulator 100 begin to start the time etc. indoor air temperature do not reach the state of design temperature, and

(2) indoor air temperature reaches the stable state of design temperature.

About the value of Δ Ta, if the Δ Ta when handle begins is made as Δ Ta1, the Δ Ta of trustworthy timing is made as Δ Ta2, Δ Ta1＞relation of Δ Ta2 when stablizing when then becoming beginning.This is the delay of constant during for the replying of the inside thermistor temp Tamb that revises infrared ray sensor 3.

In addition, under the pixel count of having confirmed to surpass absolute value judgment threshold δ is situation more than the threshold epsilon, can be judged as human body and be in before the air regulator 100.

In addition, be characterised in that, for reduce the testee do not plan to use this function and in the dead ahead of air regulator 100 by the time, can this function of starting involuntary maneuver (misoperation), the state that the condition of utilizing the pixel count that surpasses absolute value judgment threshold δ to exceed threshold epsilon continues sometime (that is to say, human body stand in the condition before the air regulator 100 effectively consciously) judgement that has human body to exist, blow out the wind that matches with the operating condition of this moment (cooling operation/heat running).

In addition, as shown in figure 50, as infrared ray sensor 3 is detected the function that the situation of judging human bodies passes to the testee, in the display part (consisting of with seven segmentations owing to show numeral) of air regulator 100 or remote controller displays section, show the counting that is formed by numerical value.

Exceed the condition of threshold epsilon according to the pixel count that surpasses absolute value judgment threshold δ, implement 3 (Figure 50 (a)), 2 (Figure 50 (b)), 1 (Figure 50 (c)) like that according to the demonstration that counts down that continues timer.Be characterised in that, after counting down, transfer to the pattern that blows out hot blast or wind from the blow-off outlet 42 of air regulator 100 take the testee as target.

Below, the automatic sensitivity of absolute value judgment threshold δ is adjusted function describe.Absolute value judgment threshold δ, with thermopile type (so-called thermopile, when the infrared ray that receives with cordless from each object radiation, can detect this energy absolute magnitude (temperature) by the infrared ray sensor that produces heat corresponding to this energy and rise electric power.Burnt electric type infrared ray sensor is that burnt electric effect, variations in temperature detect, the differential output type, relative therewith, this thermopile sensor is that heat plays electric power effect, absolute temperature (amount) detection, integration output type) the inside thermistor temp Tamb (cold junction temperature) of infrared ray sensor 3 be benchmark, Ta obtains as the Tamb+ Δ.

But, sometimes, after the firm starting of the air regulator 100 in summer etc., the impact of (with a western exposure etc.) because the radiation of sunshine, the high situation more than the inside thermistor temp Tamb of infrared ray sensor 3 of the temperature of background etc. generating chamber in.

In above-mentioned situation, the absolute value temperature of the heat picture element that is obtained by infrared ray sensor 3 all becomes more than the absolute value judgment threshold δ, easily imagination and testee's the ground misoperation without the automatic high-power running starting of remote controller that has or not that it doesn't matter.

Therefore, be characterised in that, after air regulator 100 has just begun starting, according to the situation by the absolute value temperature of the removable region-wide heat picture that obtains in the left and right sides of infrared ray sensor 3, the absolute value of absolute value judgment threshold δ is changed to raisings (raising direction side).For example, establish Δ Ta=6 ℃, the absolute value judgment threshold δ of heat picture becomes 28 ℃ by Ta=22 ℃+6 ℃ of Tamb+ Δs.Also be like this in opposite situation.

In addition, testee's side can change arbitrarily the sensitivity setting of absolute value judgment threshold δ.The sensitivity adjustment button of remote controller is made as " sensitivity is low ", " in the sensitivity ", " highly sensitive " these three patterns, and default value is set as " in the sensitivity ".Signal by in this case " highly sensitive " or " sensitivity is low " receives the numerical value that the threshold value factor constant that forms becomes Δ Ta, by reference table self with constant, can change absolute value judgment threshold δ.

Then, with Figure 51 the removable specification in the left and right sides of infrared ray sensor 3 is described.Usually, interior space environment 100 couples of testees of air regulator carries out in the situation of air conditioning, drive infrared ray sensor 3 with stepper motor at left and right directions and rotate in the predetermined angular scope, detect the temperature in room or the temperature of human body when scanning to the left and right.

In Figure 51 (a), infrared ray sensor 3 begins sensing from the left end in room.As shown in the figure, testee (people) stand in the position of the about 1.5m in the place ahead that leaves air regulator 100.

In Figure 51 (b), the sensing of infrared ray sensor 3 continues, and detects the human body end in testee's (people) left side.

In Figure 51 (c), the sensing of infrared ray sensor 3 further continues, and detects testee's (people) integral body, can detect testee's (people) horizontal width.

In the automatic high-power operation mode without remote controller, shown in Figure 51 (d) or Figure 52 (b), in the scope of the testee's (people) who detects transverse width, infrared ray sensor 3 carries out sensing repeatedly.

The testee (people) who detects not the time (Figure 51 (e)), the pixel count that surpasses absolute value judgment threshold δ becomes below the threshold epsilon, being judged as does not have the testee.

Be characterised in that, have or not judgement information based on this testee, shown in Figure 52, in the rotating drive zone of the left and right directions that is formed by stepper motor 6 of infrared ray sensor 3, only carry out rotating drive at left and right directions in the surf zone of the testee before standing on air regulator 100.

The movable range zone of the infrared ray sensor 3 when in addition, Figure 52 (a) expression is turned round usually.The movable range zone of the infrared ray sensor 3 when in addition, Figure 52 (b) expression testee detects.

Namely be, be characterised in that, after having or not decision algorithm to begin to detect by human body, the moment that breaks away from testees' surf zone at infrared ray sensor 3 makes stepper motor 6 to counter-rotation (Figure 51 (d) or Figure 52 (b)), and time is everlasting and carries out rotation and the scanning of left and right directions in testee's the human body surface zone.

Be characterised in that, angular regions (about 150.4 degree) with respect to the regulation of rotating drive when usually turning round, (about 8 degree (5 row *, 1.6 degree (a movable angle of stepper motor 6)) are little for testee's surf zone, and can become at once common operation mode after when the testee leaves before the air regulator 100, real-time performance has had significantly to be improved.

Then, the algorithm of judging the thermographic image data whether pixel count that surpasses absolute value judgment threshold δ that obtained by infrared ray sensor 3 is formed by the testee who stand in before the air regulator 100 as the thermographic image data more than the threshold epsilon is described.

Infrared ray sensor 3 according to scanned at the driving specification of the left and right directions rotating drive testee's before stand in air regulator 100 human region by stepper motor 6, to the surveyed area of heat picture, determined by the distance between air regulator 100 and testee.For this reason, at the pixel count that surpasses absolute value judgment threshold δ be the transverse width zone of the thermographic image data more than the threshold epsilon with respect in the larger situation of the human body width regions of regulation, be judged as and be not the thermographic image data that formed by the testee.

In addition, the pixel count that surpasses absolute value judgment threshold δ that occurs in the wall zone that boundary line detection algorithm in being detected by above-mentioned space identity is derived is the thermographic image data more than the threshold epsilon, is judged as too the thermographic image data that neither be formed by human body.

The pixel count that surpasses absolute value judgment threshold δ that occurs in the wall zone is more than the threshold epsilon, refers to such as the situation of having opened the curtain of closing etc.

Then, to upper bottom leaf 43, about the pendulum leaf 44 control describe.Pendulum leaf 44 is towards the state in front about Figure 53 (a) expression.In addition, Figure 53 (b) be make about pendulum leaf 44 to the state of central contracted flow.

The face position of judging the testee by heat picture and the regional determination of the absolute value temperature that obtains, shown in Figure 53 (b), about pendulum leaf 44 be controlled to and in the transverse width of human body, carry out the contracted flow air-flow, the angle control that the angle of upper bottom leaf 43 blows out according to the face position health (neck bottom) downwards from the testee.

As mentioned above, " without the automatic high-power running of remote controller " of present embodiment is characterised in that, for example, infrared ray sensor 3 detects the testee's (human body) who stood before air regulator 100 at once, blows out hot blast or cold wind take the testee as target.In addition, be characterised in that, when the testee is not before air regulator 100, transfer at once common operation mode.Therefore, has effect shown below.

(1) because the testee need not the remote controller in order to carry out high-power running, so do not bother fully.

(2) owing to can accurately judge testee's face position, thus can be above the waist or head be that target blows out hot blast, cold wind.

(3) if because so the testee not before air regulator 100, can transfer to common operation mode, at once very efficient and energy-conservation.

In addition, (apart from air regulator 100 the 1.5m degree is arranged) in the time of before the testee stand in air regulator 100, as the relation in the testee's who obtains with infrared ray sensor 3 heat picture zone (transverse width), must be testee's heat picture transverse width zone＞5 row.

Obtain 1 row amount at infrared sensor 3 and implement later in this specification of each absolute value judgement, the absolute value judgment threshold δ that the absolute value that human body has or not is judged gets the inside thermistor temp Tamb+ Δ Ta of infrared ray sensor 3.In addition, be in the threshold epsilon above situation at the pixel count that confirm to surpass absolute value judgment threshold δ, can be judged as had the human body existence before air regulator 100.

In addition, be characterised in that, in order to reduce the testee not plan to use this function in the dead ahead of air regulator 100 by the time, can this function of starting involuntary maneuver (misoperation), the condition of utilizing the pixel count that surpasses absolute value judgment threshold δ to exceed threshold epsilon continues sometime the state of (stipulated time) and (that is to say, human body stand in the condition before the air regulator 100 effectively consciously), the judgement that has human body to exist blows out the wind that matches with the operating condition of this moment (cooling operation/heat running).

In addition, be characterised in that, as infrared ray sensor 3 is detected the function that the situation of judging human bodies passes to the testee, show the counting that is formed by numerical value in display part (consisting of with seven segmentations owing to show numeral) or the remote controller displays section of air regulator 100.Exceed the condition of threshold epsilon according to the pixel count that surpasses absolute value judgment threshold δ, implement 3,2,1 like that according to the demonstration that counts down that continues timer.After counting down, the blow-off outlet 42 of transferring to air regulator 100 blows out the pattern of hot blast or cold wind take the testee as target.

In addition, be characterised in that, after the just starting of air regulator 100 in summer etc., the impact of (with a western exposure etc.) because the radiation of sunshine, the temperature of background is high to the above situation of the inside thermistor temp Tamb of infrared ray sensor 3 etc. in the generation chamber sometimes.In above-mentioned situation, the absolute value temperature of the heat picture element that is obtained by infrared ray sensor 3 all becomes more than the threshold value δ, easily imagination be with testee's the ground that has or not that it doesn't matter, misoperation occurs without the automatic high-power running starting of remote controller.Therefore, air regulator 100 just begin starting after, according to the situation by the absolute value temperature of the region-wide heat picture that movably obtains about infrared ray sensor 3, the absolute value change of threshold value δ is become raisings (raising direction side).

After human body has or not decision algorithm to begin to detect, the moment that breaks away from testee's surf zone at infrared ray sensor 3 makes stepper motor 6 to counter-rotation, in time, is everlasting and carries out rotation and the scanning of left and right directions in testee's the human body surface zone, and, angular regions with respect to the regulation of rotating drive when usually turning round, testee's surf zone is little, and can transfer at once common operation mode after when the testee leaves before the air regulator 100, thus, real-time performance has had significantly improvement.

Be in the horizontal width regions situation that the human body width regions of regulation is large relatively of the thermographic image data more than the threshold epsilon at the pixel count that surpasses absolute value judgment threshold δ, judge not formed by the testee.In addition, the pixel count that surpasses absolute value judgment threshold δ that occurs in the wall zone that the boundary line detection algorithm that detects by above-mentioned space identity is derived is the thermographic image data more than the threshold epsilon, judges too not formed by human body.

And then, heat picture and regional determination by obtained absolute value temperature are judged testee's face position, pendulum leaf 44 about control is in order to carry out the contracted flow air-flow in human body horizontal wide, the angle of upper bottom leaf 43 is pressed the angle that blows out to the health (neck bottom) of bottom from testee's face position and controlled.
