[the 1st embodiment]
It is illustrated using air conditioner 100 of the attached drawing to the 1st embodiment of the invention.
In Fig. 2, the air conditioner 100 of this 1st embodiment has thermal image acquisition unit 110, temperature sensor 120, fortune Calculation portion 130, control unit 160, shutter 171, compressor 172 and fan 173.Operational part 130 include position determining portions 131, Human body temperature calculation part 132, temperature difference value calculation part 133, warm-cold sensitivity inferring portion 134 and set point configuration part 135.It should Each constitute of air conditioner 100 also can be only fitted to times for being set to indoor indoor unit and being set in outdoor outdoor unit Meaning one.In addition, air conditioner 100 can also have the composition except these in addition to constituting.
Thermal image acquisition unit 110 is mounted to the so-called infra red thermograph before air conditioner 100.Thermal image obtains Portion 110 has the field angle Φ of left and right directions, can obtain the two-dimensional heat of the object for the front space for being present in air conditioner 100 Image.In addition, thermal image acquisition unit 110 also has field angle in the up-down direction, the front space of air conditioner 100 can be known The presence of interior people 102.Thermal image acquisition unit 110 be for example in two-dimensional-matrix-like arrangement pixel group and can be primary Property obtains the construction of two-dimensional thermal image.Other than the construction, thermal image acquisition unit 110 is also possible to for example in one-dimensional The pixel group (line sensor) of shape arrangement and one-dimensionally scanning element group and obtain the construction of two-dimensional thermal image, or can also To be that there is more than one pixel and two-dimensionally scan more than one pixel and obtain the construction of two-dimensional thermal image.This Place, the composition of thermal image acquisition unit 110 are not limited.
In this 1st embodiment, when as Figure 1A in the space of the field angle Φ in the front of air conditioner 100 There are when people 102, thermal image acquisition unit 110 can obtain the thermal image 103a of the such Temperature Distribution comprising people 102 of Figure 1B. Hereinafter, being illustrated to thermal image 103a.
In thermal image 103a, the high part of the temperature of the object in space (pixel), it is higher to be more shown as concentration. In fig. ib, the high pixel of temperature is more shown with connecing pullous color.In addition, the display about thermal image is not It is limited to this.
Currently, the dress of people 102 shown in figure 1A has jacket 102a and trousers 102b.The surface of jacket 102a, trousers 102b Temperature is close to ambient temperature.Thus, for example in the case where the room temperature that ambient temperature is 25 DEG C or so, about by thermal image acquisition unit The surface temperature of 110 people 102 detected, jacket 102a, trousers 102b part than other positions that skin exposes (face, Head, both hands, both feet) it is low.The surface temperature for the part exposed as a result, compared to skin, with relatively low concentration (with surrounding The close color of the color of pixel) display jacket 102a, trousers 102b surface temperature.In addition, in above-mentioned temperature environment, by It is lower than the temperature for wearing surface clothes in ambient temperature, therefore the feelings of ambient temperature object below are not present in the inside of field angle Φ Under condition, the concentration in the region in addition to people of thermal image 103a becomes minimum.For example, when room temperature is 25 DEG C or so, in face Skin temperature be average 33 DEG C or so, the temperature of jacket 102a is 27 DEG C or so, the temperature of both hands (exposed division) is 30 DEG C of left sides In the case that right, trousers 102b temperature is 28 DEG C or so, the temperature of double-legged (exposed division) is 29 DEG C or so, become thermal image That Temperature Distribution shown in 103a.But since the temperature-independent on the clothing surface of jacket 102a, trousers 102b etc. is in clothing Material, thickness etc., therefore sometimes up to other temperature.In addition, the surface temperature of skin is also due tos individual differences, activity etc. It is inconsistent.In addition, when people 102 is not present and under being to be present in the uniform situation of temperature of the object in field angle Φ, such as Become uniform distribution shown in the thermal image 103b of Figure 1B like that.
Next, each composition to air conditioner 100 is illustrated with function.
The Temperature Distribution obtained by thermal image acquisition unit 110 is sent to operational part 130 as thermal image.Temperature sensor 120 be thermistor, this point or parts surface that can be measured in space of thermocouple a point temperature sensing Device.Temperature sensor 120 measures ambient temperature such as the air suction inlet for being configured at air conditioner 100.In addition, warm Even the position of degree sensor 120 is configured at the place other than air suction inlet etc., here, the position is not limited.By temperature The ambient temperature that degree sensor 120 detects is sent to operational part 130.
In operational part 130, position determining portions 131 analyzes the thermal image sent from thermal image acquisition unit 110, in sky The position of interior people 102 is determined.The method for determining position of people is described later.Human body temperature calculation part 132 analysis from The thermal image that thermal image acquisition unit 110 is sent, judges the region for being inferred as being equivalent to people 102.Then, human body temperature meter The region judged is cut in calculation portion 132, and the average value of the temperature in the region of cutting is determined as human body temperature and (found out).It The calculation method of the determination method in the region of people, the average value of temperature is described afterwards.Temperature difference value calculation part 133 is obtained by human body The calculated human body temperature in temperature computation portion 132 (A value) and the ambient temperature (B value) detected by temperature sensor 120, find out The temperature difference value (C value) (that is, C=A-B) of the two.
Warm-cold sensitivity inferring portion 134 is obtained by 133 calculated temperature difference value (C value) of temperature difference value calculation part.In addition, Warm-cold sensitivity inferring portion 134 obtains the set point Tc set by set point configuration part 135.Then, warm-cold sensitivity inferring portion 134 passes through ratio Compared with temperature difference value (C value) and set point Tc, judge that people 102 feels that heat still feels cold and (is referred to as warm-cold sensitivity later).
Here, the set point Tc set by set point configuration part 135 refer to people feel it is not hot it is not cold just when temperature It spends difference value (C value) [=human body temperature (A value)-ambient temperature (B value)].That is, as shown in figure 3, if difference value compares set point Tc is small, if in other words ambient temperature rises relative to human body temperature, correspondingly with the amount of the rising, people basks, heat. On the other hand, if difference value is bigger than set point Tc, in other words ambient temperature relative to human body temperature decline, then with the decline Amount correspondingly, people feels to feel nice and cool, is cold.The value of set point Tc can for example be found out by experiment, can also pass through simulation And it calculates.
In this way, can conclude that position and the warm-cold sensitivity of the people 102 being present in field angle Φ in operational part 130.Infer The position of people 102 out and warm-cold sensitivity are input into control unit 160.Control unit 160 is according to the warm-cold sensitivity deduction in operational part 130 The warm-cold sensitivity judged in portion 134 controls shutter 171, compressor 172 and fan 173.For example, being that people 102 feels in judgement In the case where heat, control unit 160 carries out making shutter 171 towards the direction at 102 place of people and makes compressor 172 and fan 173 act and generate the control of cold wind.In this way, the ambient temperature due to people 102 declines, because this person 102 no longer feels heat, but It can be in comfortable.
In this way, by finding out around the mean temperature i.e. human body temperature (A value) and people 102 in the region for being equivalent to people 102 The temperature difference value (C value) of temperature (B value) infers warm-cold sensitivity, has the effect of as follows.
Although cannot be set for the amount of the clothing of people in general, room temperature can be set using air conditioner.Such as In the case where summer, even identical set temperature, if clothing Bao Zeren feels nice and cool, people feels heat if wearing thickness clothes Deng feeling way difference.Such as in winter in the case where, even identical set temperature, if clothing Bao Zeren feel cold, People basks if wearing thickness clothes, and feeling way is different.That is, if clothing amount is different, even if ambient temperature is identical, people's Warm-cold sensitivity also becomes different.As a result, only by the way that ambient temperature is maintained identical temperature, warm-cold sensitivity also can be dependent on clothing It measures and changes, to need to change the set temperature of air conditioner.
As in the present embodiment, the average temperature in the region for the people 102 being equivalent to including the region also comprising clothing is found out Degree is the temperature difference value (C value) of the ambient temperature (B value) of human body temperature (A value) and people 102, exactly to from also considering The heat dissipation capacity of the body of clothing is inferred.It is roughly the same degree generally, due to the energy that people absorbs daily, therefore The heat distributed from body is also preferably maintained constant.As a result, by relative to be based on ideal heat dissipation capacity and Pre-determined set point Tc compares the index i.e. temperature difference value (C value) of the heat dissipation capacity from body, cold so as to infer Thermal sensation.If can conclude that warm-cold sensitivity, even if changing the amount of clothing, without the amount for for example deliberately informing clothing by people 102, Warm-cold sensitivity can be persistently inferred with high precision in operational part 130.As a result, having regardless of the amount worn clothes, all it is not necessarily to Change set temperature one by one and is just capable of providing this effect of comfortable space.
As effect in addition to this, following effect can be expected.In the present embodiment, as from thermal image 103a The value of extraction finds out the average value for being equivalent to the region of people 102.Therefore, even enumerate the lower image of resolution also without The case where harm.For example, if temperature in order to infer warm-cold sensitivity and nose to be measured, need with to indoor several square centimeters of region Carry out the resolution of the corresponding thermal image of amount of solution picture.But according to the present embodiment, as long as being equivalent to people 102 due to finding out Region average value, therefore do not need resolution high in this way.There is the heat lower and cheap using resolution as a result, Image acquiring unit 110 is also sufficient to infer this effect of the warm-cold sensitivity of people 102.
Certainly, control unit 160 both can be with temperature difference to the drive volume of shutter 171, compressor 172 and fan 173 The bias for being equivalent to set point Tc of score value (C value) it is unrelated and be it is constant, can also correspondingly change with offset.For example, In the biggish situation of offset, the drive volume of compressor 172, fan 173 can be increased, in the lesser situation of offset, It can reduce the drive volume of compressor 172, fan 173.
In addition, several variations further explained below.
(variation 1)
In variation 1, (commonly referred to as " circadian rhythm (circadian is changed in one day based on the deep body temperature of people Rhythm) ") the case where, changes set point Tc correspondingly with the time.
Fig. 4 A is the figure for indicating the composition of the air conditioner 100 about variation 1.Variation shown in Fig. 4 A about operation Portion 130 is also equipped with the composition of circadian rhythm storage unit 136 and clock 137.In circadian rhythm storage unit 136, such as with table Form is stored with the representative circadian rhythm (deep body temperature of the people changed in one day) such as shown in Fig. 5 (a).Clock 137 be the internal clocking of air conditioner 100, and assigns the information in relation to the moment to set point configuration part 135.Set point configuration part At the time of 135 reference clock 137, based on the deep body temperature for being stored in circadian rhythm storage unit 136, to having carried out and the moment phase The set point Tc for the correction answered is set.As the variation, school has been carried out in set point configuration part 108 by being based on Positive set point Tc infers warm-cold sensitivity, so as to maintain the sense with the intraday people according to circadian rhythm to ambient temperature By the corresponding comfortable environment of variation of mode.
In addition, usually deep body temperature is higher than in the morning in the afternoon, even it may thus be appreciated that identical temperature, compared to upper Noon relatively feels warmer in the afternoon.As long as the set point Tc in afternoon is set as higher as a result, as long as and with The proportional form calibration setup point Tc of the body temperature variation of circadian rhythm.
In addition, Fig. 4 B is other figures constituted for indicating the air conditioner 100 about variation 1.Variation shown in Fig. 4 B It is the composition for replacing internal clock 137 with external clock 190.In the variation, consider get up the time, the bedtime because People and it is different, referring to possessed by people at the time of clock 190 (such as alarm clock) and clock that not air conditioner 100 has.For example, The reference position of the circadian rhythm of circadian rhythm storage unit 136 can be stored in based on the time changing of getting up for being set in clock 190 It sets.As clock 190, illumination, the sleep meter in bedroom etc. are also possible to other than alarm clock.Sleep meter is being capable of root The deductions such as the body movement according to people are fallen asleep the metrical instrument of moment, the moment of getting up, sleeping time, Depth of sleep etc..That is, according to sleeping At the time of the illumination ON/OFF of room, sleep meter value, can conclude that get up time and bedtime.Such as the variation that Sample is capable of providing for everyone optimized comfortable air conditioner.
In addition, Fig. 4 C is another figure that other are constituted for indicating the air conditioner 100 about variation 1.Become shown in Fig. 4 C Shape example is the structure for storing multiple circadian rhythms in circadian rhythm storage unit 136 and being further equipped with circadian rhythm determination unit 138 At.For circadian rhythm, the temperature variation amplitude of the people to live a regular life is larger, and live irregular people, and temperature becomes Dynamic amplitude is smaller.For example, as shown in Fig. 5 (b), round the clock by the circadian rhythm (rhythm and pace of moving things 1) of regular people and irregular people The rhythm and pace of moving things (rhythm and pace of moving things 2) is stored in circadian rhythm storage unit 136.Circadian rhythm determination unit 138 based on getting up of being obtained from clock 190 with And it go to bed and determines to be regular or irregular constantly, and judging result is notified to set point configuration part 135.Set point setting Portion 135 selects some circadian rhythm in the rhythm and pace of moving things 1 or the rhythm and pace of moving things 2 according to the judgement notified by circadian rhythm determination unit 138, Set point Tc is set.It is also regular or irregular with the living habit of people by being capable of providing as the variation Accordingly, for everyone optimized comfortable air conditioner.
In addition, here, as an example, circadian rhythm is divided into and is lived a regular life or irregular this two progress It indicates, naturally it is also possible to further refinement.In addition, circadian rhythm shown in fig. 5 is a schematical example, can also appoint Meaning ground setting body temperature amplitude of fluctuation etc., here, and is not limited thereof.
(variation 2)
In variation 2, based on if cause the heat dissipation capacity from body to increase because of movement, if compared to peace and quiet when feel temperature Warm this point, changes set point Tc correspondingly with activity.
Fig. 6 is the figure for indicating the composition of the air conditioner 100 about variation 2.In variation shown in Fig. 6, operational part 130 are also equipped with the composition of activity operational part 139 and buffer 140.For example, in Fig. 7, if thermal image 103c is moment T1 Thermal image, if thermal image 103d be the stipulated time more late than moment T1 at the time of T2 thermal image.At this point, position determining portions 131 The position of the people 102 of moment T1 is determined according to thermal image 103c, or determines according to thermal image 103d the position of the people 102 of moment T2 It sets.Buffer 140 stores the position of the people determined at various moments by position determining portions 131.Activity operational part 139 is according to depositing The variation for being stored in the position of the people of buffer 140 infers the activity of people 102, and is sent to set point configuration part 135.Setting Point configuration part 135 is corrected set point Tc based on the activity inferred by activity operational part 139.According to the variation, It can conclude that warm-cold sensitivity corresponding with the activity of people.Based on by inferring the warm-cold sensitivity obtained, control unit 160 can be with people's Activity correspondingly controls compressor 172, fan 173.Thereby, it is possible to provide the surrounding's ring that can be felt comfortable activity Border.
In addition, quantitative change of usually radiating is more, therefore correspondingly raises set point with activity in the biggish situation of activity The case where Tc, increases.In addition, here, be conceived to the variation of the position of people and infer activity, but can also to and inhuman position The position for the high-temperature portion such as hand set is monitored and infers activity.In this way, even if at seat when such as ironing The case where upper progress operation, is inferior, also can conclude that activity, therefore be capable of providing more comfortable air conditioner.
In addition, as an example for inferring activity, being illustrated using the people's in thermal image in the variation 2 The method of change in location.But as long as can conclude that activity, so that it may be its other party in addition to the method for using thermal image The estimating method of method, activity is not specifically limited.
(variation 3)
In variation 3, even based on identical temperature, in the feeling way in summer and winter also different this point, Change set point Tc correspondingly with season.
Especially since the temperature difference in the four seasons of Japan understand it is discernable, even it may thus be appreciated that identical temperature, in the summer The feeling way in season and winter is also different.In general, in the hot season of summer etc., due to bodily habit sweltering heat, i.e., Keep ambient temperature higher (such as 28 DEG C), can also feel proper temperature.On the contrary, cold season is waited in winter, since body is practised It has been used to cold, therefore even if ambient temperature is lower (such as 20 DEG C), can have also felt proper temperature.As a result, in summer, even if surrounding The temperature difference value of temperature and the mean temperature of people is smaller than other seasons, can also feel comfortable, in winter, ambient temperature and people's The temperature difference value of mean temperature can feel comfortable when bigger than other seasons.
Fig. 8 A is the figure for indicating the composition of the air conditioner 100 about variation 3.In the variation shown in Fig. 8 A, operation Portion 130 is also equipped with heating/refrigeration judging part 141 composition.Heating/refrigeration judging part 141 judges that air conditioner 100 is being made Control model as heat run or refrigeration operation.Set point configuration part 135 is based on the control in heating/refrigeration judging part 141 The judging result of molding formula carrys out calibration setup point Tc.For example, set point Tc is set as if control model is refrigeration operation 3.0 DEG C, if control model is heating operation, set point Tc is set as 4.0 DEG C.In such manner, it is possible to provide also and based on season Complying with for the warm-cold sensitivity of the body of section be adaptable, comfortable air conditioner.
In addition, Fig. 8 B is other figures constituted for indicating the air conditioner 100 about variation 3.Variation shown in Fig. 8 B It is not heat/freeze the composition of judging part 141 but the ambient temperature detected by temperature sensor 120 is input to and is set The composition in fixed-point settings portion 135.Set point configuration part 135 (utilizes sky according to the ambient temperature detected by temperature sensor 120 Adjust the temperature made before indoor become comfortably) infer current season, carry out the correction of set point Tc.Certainly, set point is set Portion 135 can not also infer season, but based on the direct calibration setup point of ambient temperature detected by temperature sensor 120 Tc.In addition, ambient temperature is also possible to ambient temperature that warm-cold sensitivity inferring portion 134 is inferred from thermal image (later in variation 7 Narration).
Further, Fig. 8 C is another figure that other are constituted for indicating the air conditioner 100 about variation 3.Shown in Fig. 8 C Variation in, operational part 130 is also equipped with the composition in calendar portion 142.Calendar portion 142 has dated information.Set point setting Portion 135 infers current season according to the date obtained from calendar portion 142, carries out the correction of set point Tc.In such manner, it is possible to provide Also with the body based on season is adaptable to complying with for warm-cold sensitivity, comfortable air conditioner.
(variation 4)
In variation 4, though based in identical environment, warm-cold sensitivity that people is experienced there is also individual differences this A bit, discrimination corporally changes set point Tc.
As the method for distinguishing individual from thermal image, such as it is able to detect height.For example, the heat of X is shown in FIG. 10 The thermal image 103f of image 103e and Y.About the height of people, can be passed through according to standing place and the height of the people on image Calculating is simply found out.That is, distance of the people away from air conditioner 100 is learnt upper or under according to the standing place on image, into And the height of the people according to acquisition, height can be calculated.It, can be according to body for the Y of the X and thermal image 103f of thermal image 103e High different discriminations are personal.
Fig. 9 is the figure for indicating the composition of the air conditioner 100 about variation 4.In variation shown in Fig. 9, operational part 130 are also equipped with the composition of people's discrimination section 143 and buffer 144.The analysis of people's discrimination section 143 is obtained by thermal image acquisition unit 110 Thermal image, individual is distinguished according to height as described above.Buffer 144 is previously stored with everyone (in the example In be X and Y) set point Tc.The buffer 144 inputs personal discrimination results from people's discrimination section 143, will be directed to the individual The set point Tc of storage is sent to set point configuration part 135.
Here, everyone set point Tc can be determined as follows.For example, can be by thermal image acquisition unit The position of 110 acquisition thermal images makes personal standing, makes temperature change and acts air conditioner 100.Then, feeling not hot At the time of not cold, specific signal (such as being sent with remote controler (not shown)) is inputted from individual to air conditioner 100.Air-conditioning The ambient temperature obtained by temperature sensor 120 when machine 100 is entered according to specific signal, by human body temperature calculation part 132 human body temperatures etc. determined calculate set point, by the set point and the personal height information that is obtained by people's discrimination section 143 It is stored in buffer 144 together.In addition, can also be added when setting everyone set point Tc by oneself personal informing Information (cold, To Be Protected from Heat, sympotoms caused by cold factors (Japanese: cold え disease, English: sensitivity to cold) etc.).For example, oneself is informed The set point of the Y of sympotoms caused by cold factors is set as lower.It sets in this way, due to control heat dissipation capacity to the direction of relative drop Mode function, even therefore have can sympotoms caused by cold factors be also difficult to such effect that feels cold.
In this way, set point configuration part 135 obtains from buffer 144 and sets setting for the individual distinguished by people's discrimination section 143 Pinpoint Tc.Then, warm-cold sensitivity inferring portion 134 judges warm-cold sensitivity based on the set point Tc of the individual.It can be to a thereby, it is possible to realize People realizes the air conditioner of optimized ambient temperature.
In addition, in the above-described embodiments, calculating height according to the thermal image obtained by thermal image acquisition unit 110 and carrying out a The discrimination of people.But method for distinguishing is not limited to this method for personal distinguishing, is also possible to other methods.For example, both can root It distinguishes personal according to the difference of Temperature Distribution, can also distinguish personal based on the image of CCD camera set in addition etc..
[the determination method of human body temperature (A value)]
Next, the 1 mean temperature i.e. human temperature for illustrating region in operational part 130, being equivalent to people 102 referring to Fig.1 Spend the calculation method of (A value).
For example, as described above, in the case where room temperature is 25 DEG C or so, the skin temperature of face is average 33 DEG C of left sides The right side, the temperature of jacket 102a are 27 DEG C or so, and the temperature of both hands (exposed division) is 30 DEG C or so, and the temperature of trousers 102b is 28 DEG C Left and right, the temperature of double-legged (exposed division) are 29 DEG C or so.Thereby, it is possible to by with by temperature sensor 120 detect around temperature Degree compares and is the region of predetermined temperature or more as the region for being equivalent to people 102.In this way, operational part 130 calculate it is related For calculate the region of the people of human body temperature (A value) or be output to control unit 160 people 102 position information.
For example, if in this case inferring pixel portion of high 1 DEG C or more than ambient temperature (25 DEG C) for people 102, The region that the thick line as shown in Figure 11 (a) can be surrounded is as the region for being equivalent to people.In this way, can also be above by regulation Pixel portion is determined as being equivalent to the region of people.It in addition to this, can also will be more than 26 DEG C or more of pixel portion specified quantity Continuous situation is added as the condition for determining the region of people.Such as Figure 11 (b) like that, in thermal image, sometimes The region of the luminaire to be generated heat when including lighting with 26 DEG C or more etc..It in this case, as long as will for example 26 DEG C or more 10 pixel of continuous pixels more than region as people identify, would not using the thermal objects of these luminaires etc. as people and It detects.It thereby, it is possible to accurately detect people, therefore can reliably infer warm-cold sensitivity, comfortable ambient enviroment is provided.
Moreover, in the above-described embodiments, will be equivalent to the region that ambient temperature is 1 DEG C or more and be set as being equivalent to the area of people Domain however, you can also not only set lower limit temperature, but also sets ceiling temperature.For example, ceiling temperature can be also set as to 40 DEG C, It is not set as the region higher than 40 DEG C to be equivalent to the region of people.In this case, such as Figure 11 (c) is such, it is assumed that in chest Pocket in there are the principal element other than metabolism of human body etc. of smart phone etc. due to the object that generates heat and the region than 40 In the case where DEG C height, which can also be removed from the region for be equivalent to people.In such manner, it is possible to which accurately prediction people is because of metabolism The amount of heat dissipation, therefore can more precisely infer warm-cold sensitivity, more comfortable ambient enviroment is provided.
In addition, in this embodiment, by whether 1 DEG C higher than ambient temperature or more as threshold value set the area for being equivalent to people Domain, but can certainly independently be determined as such as 26 DEG C with ambient temperature, it is free to set.In addition, as continuous Pixel number is set as 10 pixels herein as an example, is not limited to 10 pixels certainly, as long as obtaining with the thermal image used The specification etc. of mechanism is correspondingly suitably set.In addition, being set as 40 DEG C as ceiling temperature, but this is also an example certainly Son also can be set as other temperature, be not limited to 40 DEG C.In addition to this, can also compare according to time series acquisition Thermal image will be present movable part as the region for being equivalent to people 102, herein, not limit its mode.
In addition, herein, as optimal composition, will be equivalent to people's 102 according to thermal image in the inside of operational part 130 The temperature averages in region are determined and (are found out) as human body temperature (A value), infer the warm-cold sensitivity of people 102.But it as long as can Inferred by the difference value between acquisition and ambient temperature comprising the heat dissipation capacity including clothing, others can also be worth As human body temperature.For example, it may be being equivalent to the integrated value of the temperature in the region of people 102, equally it is also possible to maximum value, also It can be other mode values, median etc., herein and be not limited thereof.
In addition, so far, describing the case where related ambient temperature is 25 DEG C or so.But in ambient temperature height to for example In the case where 33 DEG C or so, the skin temperature relative to face is average 33 DEG C or so, jacket 102a, trousers 102b temperature also with Ambient temperature is very nearly the same, both reaches 33 DEG C or so.In addition, due to both hands (exposed division), both feet temperature also with surrounding Temperature is same, and therefore, it is difficult to the region of people 102 is detected on thermal image.
But in general, if ambient temperature is 33 DEG C or so, not feel sultry from the heat dissipation of skin etc., body Situation.Therefore, at this point, can also not have to operational part 130 judges (operation) warm-cold sensitivity and the position of people, but by control unit 160 directly judge ambient temperature and start refrigeration operation.Composition at this time is indicated in Figure 12.In this way, being in ambient temperature In the case where more than predetermined temperature, with warm-cold sensitivity it is irrelevant start to freeze, so that ambient temperature is become predetermined temperature (such as 33 DEG C) below.If ambient temperature reaches predetermined temperature or less (defined temperature field), the region of people, therefore energy can be distinguished Enough operational parts 130 infer warm-cold sensitivity to provide comfortable ambient enviroment.
In addition, here, making 33 DEG C of predetermined temperature and being illustrated, but not limited to this.As long as than the face of people Predetermined temperature can also be set as lower by the low temperature of the surface temperature of the extending part in portion etc., here, not limit its temperature Degree, range.Using the warm-cold sensitivity inferring portion 134 that so far describes infer warm-cold sensitivity and to the processing that control unit 160 is controlled, with Execute to ambient temperature unrelated (not limiting temperature range).But such as ambient enviroment be 10 DEG C when, whoso can all be felt To cold, if ambient enviroment is 30 DEG C, whoso can all feel heat.Accordingly it is also possible to be limited to by temperature sensor 120 The ambient temperature of measurement within the limits prescribed the case where, using warm-cold sensitivity inferring portion 134 infer warm-cold sensitivity and to control unit 160 It is controlled.Moreover, can all feel cold in the case where defined range ambient temperature below as whoso, it can To infer without warm-cold sensitivity but heating operation is carried out, in the case where ambient temperature more than the range, as either Everybody can feel heat, can infer without warm-cold sensitivity but carry out refrigeration operation.It is brought in such manner, it is possible to reduce operational part 130 Calculating load, provide consumption electric power less air conditioner.In addition, here, as the ambient temperature for carrying out warm-cold sensitivity deduction Range be set as 10 DEG C to 30 DEG C, but the range is not limited certainly, can be set freely in the range of not departing from purport. Additionally, it is not necessary to be mentioned that, it is above-mentioned be defined in carried out within the scope of predetermined temperature warm-cold sensitivity deduction effect be not rely on it is cold Thermal sensation estimating method, even method in addition to the warm-cold sensitivity estimating method described in the present embodiment also effect having the same Fruit.
In addition, the thermal image (benchmark thermal image) when people is not present in the range of field angle Φ is obtained in advance, in operation The difference value of the thermal image and benchmark thermal image actually obtained is obtained in portion 130, so as to directly find out as human body temperature The temperature difference value (C value) of the difference value of (A value) and ambient temperature (B value).It is explained using Figure 13 and Figure 14.Figure Thermal image 103g shown in 13 (a) is the benchmark thermal image obtained in the case where people 102 is not present in field angle Φ.Due to There are luminaires in field angle Φ, therefore there are the higher regions of temperature in the region of luminaire.Shown in Figure 14 Composition in, which is stored in background data buffer 145.Next, thermal image 103h shown in Figure 13 (b) It is the thermal image obtained in the case where people 102 is present in field angle Φ.Thermal image 103h is output to difference value processing unit 146.Difference value processing unit 146 obtains the difference of thermal image 103h with the thermal image 103g for being stored in background data buffer 145 Value.The image becomes thermal image 103i shown in Figure 13 (c).Since the thermal image has been subtracted the part of ambient temperature, C value is found out without carrying out subtraction process the composition such as Fig. 2 in operational part 130.For the thermal image 103i of acquisition, lead to The average value for obtaining each pixel using region more than predetermined temperature as the region for being equivalent to people 102 is crossed, temperature can be found out Difference value (C value).Then, based on the temperature difference value (C value) found out, warm-cold sensitivity can be inferred in warm-cold sensitivity inferring portion 134.
In this way, this effect of air conditioner can more inexpensively be constituted by having due to no longer needing temperature sensor 120 Fruit.In addition, can also be reliably detected out and be equivalent to by acquisition difference value even if there are the thermal objects of luminaire etc. The region of people.In addition, here, in field angle Φ whether someone, the thermal map of acquisition can also be compared according to time series Picture, there is no be judged as nobody in the case where variation more than the stipulated time.Stipulated time is, for example, 5 minutes or so appropriate, Both it can suitably be set according to specification, and also can be set to and be able to carry out adjustment.
In addition, air conditioner 100 is typically found in the position higher than the position of people 102, in general, the high temperature in position become compared with High temperature.Accordingly it is also possible to which the value of certain temperature lower than the value measured by temperature sensor 120 is set as ambient temperature (B value).Alternatively, it is also possible to be provided with air conditioner 100 height, position and other conditions correspondingly, make by temperature sensing The value that device 120 measures deviates certain temperature to be set as ambient temperature (B value).
In addition, variation further explained below.
Here, air conditioner 100 also has receiver 180.In the above-described embodiments, installation has been used as temperature sensor In the temperature sensor 120 of air conditioner 100, here, about being carried out with being different from the temperature sensor set in addition of air conditioner 100 The case where measurement, is illustrated.
(variation 5)
Figure 15 A is the figure for indicating the composition of the air conditioner 100 about variation 5.Variation shown in Figure 15 A is to be different from 100 ground of air conditioner is additionally provided with the composition of remote controler 191.Remote controler 191 has temperature sensor 193 and transmitter 194.It is logical Often, remote controler 191 is used in the opening and close of the movement of air conditioner 100, the adjustment of wind direction, air quantity, temperature etc., in the variation 5 In, temperature sensor 193 is added in remote controler 191 to measure ambient temperature.
Transmitter 194 is output to by the ambient temperature that temperature sensor 193 measures, and from there in air conditioner Receiver 180 in 100 is transmitted wirelessly.Movement after this is identical as above content.In general, the position of remote controler 191 In the main body than air conditioner 100 close to the position of indoor people, therefore become by the temperature that remote controler 191 measures closer to room The temperature of the ambient temperature of interior people.The warm-cold sensitivity inferred in operational part 130 as a result, also further improves precision, can More comfortable ambient enviroment is provided.
(variation 6)
Figure 15 B is the figure for indicating the composition of the air conditioner 100 about variation 6.
Variation shown in Figure 15 B is the composition for being different from 100 ground of air conditioner and being additionally provided with wearable terminal 192.With it is distant Control device 191 is identical, and wearable (wearable) terminal 192 has temperature sensor 193 and transmitter 194.Wearable terminal 192 It is dressed by indoor people.As wearable terminal 192, the e.g. activities meter (active amount meter) of bracelet type Etc. various terminals either smart phone, is also possible to the smartwatch etc. of Wristwatch-type, can also be intelligence in addition to this The others terminal such as glasses.By by be installed on ambient temperature that this temperature sensor 193 for being worn over device at one's side measures from Transmitter 194 is sent to the receiver 180 of air conditioner 100.Movement later is identical as above content.
In this way, for the ambient temperature of the device measurement being worn at one's side by wearable terminal 192 etc., due to directly measuring The ambient temperature of people, therefore the precision for the warm-cold sensitivity inferred in operational part 130 further increases, and is capable of providing more comfortable week Collarette border.
(variation 7)
The case where inferring ambient temperature to according to thermal image and not temperature sensor is illustrated.Figure 16 be indicate about The figure of the composition of the air conditioner 100 of variation 7.Replace temperature sensor 120 in the composition of Figure 16 and has ambient temperature deduction This point of portion 147, it is different from the composition of Fig. 2.Ambient temperature inferring portion 147 inputs thermal image from thermal image acquisition unit 110, and calculates Ambient temperature (B value) out.Here, the processing in ambient temperature inferring portion 147 is illustrated.
Figure 17 (a) is the thermal image 103j shot by thermal image acquisition unit 110, and is set as comprising being equivalent to people 102 and shining The region of funerary objects tool.In addition, setting ambient temperature as 23 DEG C or so, the skin temperature of face is averagely 33 DEG C or so, jacket 102a's Temperature is 27 DEG C or so, and the temperature of both hands (exposed division) is 30 DEG C or so, and the temperature of trousers 102b is 28 DEG C or so, both feet (dew Portion out) temperature be 29 DEG C or so.
Statistical chart (the histogram: histogram, column of thermal image 103j is calculated in ambient temperature inferring portion 147 Figure).The statistical chart is indicated in Figure 17 (b).Example as described above is such, and consideration sets 26 DEG C to 40 DEG C among this For the region for being equivalent to people, and it will in addition to this be set as indoor background area.It then, will be other than being equivalent to the people 102 23 DEG C of mode value detected as ambient temperature (B value).In thermal image 103j, other than being equivalent to people In region, there is also the regions for being equivalent to luminaire, but the ratio of the usually heater in addition to indoor people is smaller, Therefore by obtaining the mode value in the region other than being equivalent to people, ambient temperature can accurately be found out.In this way, energy Temperature sensor 120 is enough omitted, therefore is capable of providing more cheap air conditioner.
(variation 8)
It can also be answered in by the temperature for temperature sensor 120 (such as Fig. 2 the constitute) measurement for being installed on air conditioner 100 It is calculated with statistical chart.For example, being measured in temperature accuracy ± 2 DEG C of temperature sensor 120, in turn by temperature sensor 120 Temperature such as Figure 17 (c), can also will be in the statistical chart of the thermal image 103j in 24 DEG C ± 2 DEG C like that in the case where 24 DEG C Mode value (in Figure 17 (c) be 23 DEG C) be used as ambient temperature (B value).In such manner, it is possible to more precisely infer ambient temperature (B value).In addition, in general, air conditioner is also installed on higher position, therefore the temperature measured by temperature sensor 120 indoors It is mostly higher than the ambient temperature of people.It as a result, can also will be in the temperature of predetermined temperature lower than temperature measured by temperature sensor 120 It joined existence range of the range of measured deviation etc. as ambient temperature (B value) in degree.
(variation 9)
Infer that the other methods of ambient temperature are illustrated to according to thermal image.Figure 18 (a) indicates that air conditioner 100 is installed on The state of indoor wall surface, thermal image acquisition unit 110 have the field angle θ of up and down direction.In the field angle θ of the up and down direction Among, thermal image acquisition unit 110 is configured with comprising indoor ceiling 104 and the mode on floor 105.In addition, indoors, people 102 stand and enter the inside of the field angle θ of the up and down direction of thermal image acquisition unit 110.It will be obtained in this state by thermal image The thermal image for taking portion 110 to obtain is shown schematically in Figure 18 (b) as thermal image 103k.In thermal image 103k, remove Be equivalent to except the region of people 102, there is also be equivalent to the region of ceiling 104 be equivalent to floor 105 region this two Person.Here, the also temperature of the temperature in the available region for being equivalent to floor 105 and the region for being equivalent to ceiling 104, and general Ambient temperature of the average value as people 102.Rise generally, due to warm air, therefore the temperature of ceiling is than the temperature on floor Degree is high.It is located at the substantially centre on ceiling and floor around position as where people, is equivalent to smallpox by obtaining The average value of the temperature in the region of plate 104 and the temperature for being equivalent to floor 105, can accurately infer ambient temperature.In this way, Since temperature sensor 120 can be omitted, it is capable of providing more cheap air conditioner.
In addition, being equivalent to the region on floor 105 can also be used as temperature near the standing place of people 102, it is equivalent to day The temperature in the region of card 104 can also be extracted among the pixel of the most uplink of thermal image 103k, selection method not by It limits.In addition, here, using temperature and the temperature in the region for being equivalent to floor 105 in the region for being equivalent to ceiling 104 Average value is but it is also possible to be value except the average, and for example, it can be in the case where inferring the temperature of lower position It improves the ratio for the temperature in region for being equivalent to floor 105, improve phase in the case where inferring the temperature of higher position on the contrary When the ratio of the temperature in the region of ceiling 104 calculates, which is not limited.
(variation 10)
So far, describing for people 102 is common positive thermal image, actual indoor situation, in addition to this Also consider other various situations.Here, as other situations, the case where to towards rear and just in and out of the shape in cold place The operation method of the relevant operational part of condition is illustrated.
The thermal image 103m of Figure 19 (a) is directed towards the thermal image of positive people 102.The thermal image 103n of Figure 19 (b) is court The thermal image of people 102 rearward.The thermal image 103p of Figure 19 (c) is after just entering the room from cold place towards positive people 102 thermal image.Figure 20 A is the figure for indicating the composition of the air conditioner 100 about variation 10.The variation shown in Figure 20 A In, the composition of the human body temperature calculation part 148 of operational part 130 is different from the composition of Fig. 2.
Human body temperature calculation part 148 analyzes the thermal image sent from thermal image acquisition unit 110, finds out and is equivalent to people's 102 The average value (A value) of the temperature in region.In addition, human body temperature calculation part 148, which is found out, is equivalent to the temperature in the region of people 102 most Big value (D value).Then, in human body temperature calculation part 148, according to the maximum value (D value) of the average value (A value) of temperature and temperature Distinguish what state the people 102 in thermal image is now arranged in.For example, the average value (A value) in temperature does not enter defined range Interior (such as 25 DEG C ± 3 DEG C) but in 22 DEG C of situations below, be judged as and just enter the room from cold place and whole body is cold.Together Sample is judged as and just enters the room from hot place in the case where 28 DEG C or more.25 DEG C ± 3 are in the average value (A value) of temperature DEG C range and temperature maximum value (D value) be such as 31 DEG C of situations below under, be judged as towards rear.This is because logical Often, the temperature of face is 33 DEG C or so, if this temperature below, then it is assumed that be not capable of measuring the temperature of face, therefore be judged as Towards rear.
In this way, can conclude that shape people 102 is in by the average value (A value) and maximum value (D value) of combination temp State.Accordingly, for thermal image 103p shown in Figure 19 (c), as shown in Figure 19 (d), the average value (A value) of temperature is in 25 Outside DEG C ± 3 DEG C of range, therefore it is judged as the state entered the room from cold place.Although temperature is put down for thermal image 103n Mean value (A value) is in the range of 25 DEG C ± 3 DEG C, but since the maximum value of temperature (D value) is 31 DEG C hereinafter, being therefore judged as not It is in an interim state and be directed towards rear.For thermal image 103m, the average value (A value) of temperature is in 25 DEG C ± 3 DEG C of range Interior, the maximum value (D value) of temperature is also 31 DEG C or more, therefore is judged as and is not at transition state and is directed towards front.
For being judged as towards positive thermal image 103m, it regard the average value (A value) of temperature as human body temperature calculation part Calculated result, i.e. human body temperature (E value) in 148.On the other hand, it is being judged as from cold as thermal image 103p In the case where the state that place is entered the room, infer without warm-cold sensitivity but directly issue and instruct to control unit 160, makes one 102 temperature It is warm.In addition, in the case where being judged as thermal image 103n towards rear, by the rule of the average value (A value) of temperature Corrected value as the constant times of definite value is as human body temperature (E value).Obtain the human body temperature (E value) that sets in this way with from The difference value for the ambient temperature (B value) that temperature sensor 120 obtains is inferred so as to find out temperature difference value (C value) in warm-cold sensitivity Warm-cold sensitivity is inferred in portion 134 and is controlled.Even in this way, the transition state of people, not towards positive state, also can be into Row is corresponding with the warm-cold sensitivity of people to be controlled.
In addition, as long as there is the body state judging part 149 for the state that can judge human body as the composition of Figure 20 B , the average value (A value) that human body temperature calculation part 148 corrects temperature can also not had to.In other words, sentence with body state The disconnected judgement of portion 149 is people 102 towards in the case where rear, can pass through the value with 135 calibration setup point Tc of set point configuration part It carries out warm-cold sensitivity deduction, when judgement is the state entered the room from cold place, can also still infer without warm-cold sensitivity But it is warm directly to make one 102 to the sending instruction of control unit 160.
In addition, among the above, as the putting down according to temperature in human body temperature calculation part 148, body state judging part 149 Mean value (A value), maximum value (D value) judge the benchmark of the state of people, and showing temperature range is 25 DEG C ± 3 DEG C, maximum value 31 DEG C this judgement benchmark.But these temperature certainly example, other values can also be used.
Moreover, judgement is that people 102 is continued towards rear specified time limit (such as 10 minutes in body state judging part 149 Left and right) more than in the case where, the thermal image that also can use alert mechanism (not shown) warning people 102 towards air conditioner 100 obtains Take the direction in portion 110.In this way, without changing set point Tc or correcting the average value (A value) of temperature, it will be able to accurately infer Warm-cold sensitivity, therefore it is capable of providing comfortable ambient enviroment.In addition, mechanism by way of caution, except being guided except through sound, Both it can make to be installed on main body, display lamp (not shown) etc. and light, remote controler etc. can also be made to show its order, can also be Other mechanisms are not defined the mechanism here.It, can be in addition, the specified time limit given a warning can not be 10 minutes It is longer or shorter.
(variation 11)
So far, the entirety in the region for being equivalent to people in thermal image is summarized as one and is handled, in the deformation In example, the example in the case that the region division that will be equivalent to people is handled for multiple human bodies is illustrated.Figure 22 is Indicate the figure of the composition of the air conditioner 100 about variation 11.In the variation shown in Figure 22, operational part 130 has position Discrimination section 150 and weighted addition portion 151.
For example, the temperature of the people of sympotoms caused by cold factors especially trick is easy to be become by external temperature influence close to ambient temperature Temperature.In this case, the difference of the position as hand, foot and ambient temperature becomes smaller, and such case is judged as heat dissipation It measures smaller.Therefore, in the variation, weighting is imposed to each human body.Shown in the such as Figure 21 of position discrimination section 150 that Sample distinguishes head, body part, hand, the leg, foot being equivalent in the region of people 102, is divided into five human bodies.So Afterwards, average value of the position discrimination section 150 to each calculating temperature of the multiple human bodies marked off.Weighted addition portion 151 The temperature averages by the calculated each human body of position discrimination section 150 are inputted, and flat to the temperature of each human body Mean value assigns weighting.Temperature difference value calculation part 133 is according to the average value (F value) and ambient temperature (B value) of the temperature after weighting Find out temperature difference value (C value).Alternatively, it is also possible to not calculate the temperature averages of everyone body region, respectively to each human body The temperature for whole pixels that position is included assigns weighting, also can get identical temperature averages (F value) as a result.
Here, reduce the human body (exposed division) as exposing hand and foot weighting in the case where, energy Enough warm-cold sensitivities for more accurately reflecting people, and can accurately infer warm-cold sensitivity.In addition, here, as human body, using Head, body part, hand, leg, foot this five, but the discrimination of five human bodies is not limited, both can to more More human bodies are distinguished, can also be distinguished less human body.Moreover, adding about each human body Power, can also combine with that people's discrimination section 143 shown in Fig. 9 to carry out.It is distinguished that is, can also assign by people's discrimination section 143 , the weighting of each human body to vary with each individual.At this point, the coefficient in buffer 144 with weighting can also be made.
(variation 12)
Figure 23 is the figure for indicating the composition of the air conditioner 100 about variation 12.
In the variation shown in Figure 23, operational part 130 has weighted addition portion 151 and temperature range cutting part 152.
Temperature range cutting part 152 is as shown in Figure 24 by the region segmentation for being equivalent to people 102 in acquired thermal image At multiple (being six in Figure 24) temperature ranges.In turn, temperature range cutting part 152 analyzes the pixel number in each temperature range With how many a pixels.Weighted addition portion 151 assigns weighting to each range being partitioned by temperature range cutting part 152.For example, Among the temperature range being partitioned into, the weighting of the range close to the relatively low temperature of external air temperature also can reduce.So Afterwards, weighted addition portion 151 calculates the average value of each temperature range after weighting as human body temperature (F value).Temperature difference value Calculation part 133 finds out temperature difference according to by the calculated human body temperature in weighted addition portion 151 (F value) and ambient temperature (B value) It is worth (C value).Even if also can more accurately infer warm-cold sensitivity in the case where hand, foot are cold as a result,.
In addition, here, as the countermeasure of sympotoms caused by cold factors, the weighting of low temperature side is reduced among the region for being equivalent to people 102.But It is that the weighting coefficient can also be changed according to purpose and arbitrarily, here, the coefficient and segmentation number is not defined.
(variation 13)
Next, processing when being sitting in the rear of table 106 to people 102 is illustrated.Figure 26 is indicated about variation 13 Air conditioner 100 composition figure.In the variation shown in Figure 26, operational part 130 has layout inferring portion 153.
It is shot due to the furniture configured with table, frame etc. by thermal image acquisition unit 110 in the interior in living room etc. Thermal image in, the case where being blocked there are a part of body and carried out shooting.For example, if in the people as Figure 25 (a) 102 lower part of the body shoots thermal image in the case where being blocked by table 106, then as the thermal image 103r of Figure 25 (b), takes down Half body is still blocked.In addition, the dotted line in Figure 25 (b) is supplemented to indicate the configuration of table 106, it is not offered as temperature letter Breath.Therefore, layout inferring portion 153 infers the layout in room according to the thermal image obtained from thermal image acquisition unit 110, and according to The layout of deduction is the temperature information of whole body or a part of body come the surface temperature information for inferring people 102 obtained Temperature information.In the case where as thermal image 103r being only the image of the upper part of the body of body, in the region that judgement is people 102 Interior, the ratio in the region of the relatively high face of temperature becomes larger, because this person 102 surface temperature average value than body The average value of surface temperature is high.Infer that thermal image 103r is only the image of the upper part of the body of body in layout inferring portion 153 as a result, In the case of, improve the set point Tc set in set point configuration part 135.Even if as a result, in the family configured with table 106, frame etc. In that case of tool, warm-cold sensitivity also can be accurately inferred.Thereby, it is possible to realize the control for being in the air conditioner of virtual condition System.
Furthermore it is possible to be foot by the position prediction of lower side in thermal image, distinguishing region for people.Cloth as a result, Position of office's inferring portion 153 for example in the thermal image obtained by thermal image acquisition unit 110 to the lower side for distinguishing the region for people Lasting plotting (being in other words the track for finding out people's walking) is set, and by the region not being plotted in region as configured with table etc. The region of furniture learn, so as to infer layout.The method of deduction is not limited to this method certainly, can also be with not scheming The CCD camera etc. shown is shot, and is inferred by image recognition, here, is not defined to this method.
(variation 14)
Next, the warm-cold sensitivity deduction to the people towards horizontal side is illustrated.Figure 28 is the sky indicated about variation 14 The figure of the composition of tune machine 100.In the variation shown in Figure 28, operational part 130 has people towards inferring portion 154.
In the case where people is towards horizontal side, compared with towards in positive situation, the relatively high face portion of temperature The ratio in region reduces, therefore the average value of the surface temperature of the people found out according to thermal image reduces.Therefore, people is towards inferring portion 154 infer the direction of people according to the thermal image obtained from thermal image acquisition unit 110.For example, being inferred as according to thermal image 103s People 102 is towards in the case where right side, and people is towards inferring portion 154 as being averaged according to the calculated surface temperature of thermal image 103s Value is lower calculated, and reduces the set point Tc set in set point configuration part 108.Even if as a result, in people not towards just In the case where face, warm-cold sensitivity also can be accurately inferred.Thereby, it is possible to realize the control for being in the air conditioner of virtual condition.
In addition, using people towards inferring portion 154, learn for example in the case where people is towards horizontal side, as thermal image 103s that It is not bilateral symmetry that sample, which is identified as the Temperature Distribution on the top of people 102,.Thereby, it is possible to be pushed away according to the Temperature Distribution on image top The direction of disconnected people.In addition, here, being illustrated to towards the case where horizontal side, capable of being also directed towards the feelings at rear certainly Condition.For example, although the temperature of the face of people is usually 33 DEG C or so, the Temperature Distribution on the top in the region for being equivalent to people Maximum value be significantly lower than 33 DEG C in the case where, be inferred as being influenced by hair and temperature being caused lower to be measured.As a result, In this case, it can conclude that as towards rear.Certainly, infer that the method for the direction of people is also possible to other methods, such as It can be shot with CCD camera (not shown) etc., be inferred by identifying purpose position etc. by image recognition, it is here, not right This method is defined.
[the 2nd embodiment]
The air conditioner 200 of 2nd embodiment of the invention is in the air conditioner 100 shown in the 1st embodiment, can Constituting for notification unit 210 is equipped with by the position of 102 visual confirmation of people.
Figure 29 is the figure that outlined the appearance of air conditioner 200 of the 2nd embodiment of the invention.It is empty in Figure 29 Tune machine 200 includes to be installed on thermal image acquisition unit 110 before shell, be installed on internal operational part 230 and control unit 160.Thermal image acquisition unit 110 is identical as the composition illustrated in the 1st embodiment, and the field angle Φ with left and right directions, The two-dimensional thermal image of the object for the front space for being present in air conditioner 200 can be measured.The thermal image that can obtain with the 1st The thermal image described in embodiment is identical, therefore omits explanation again here.
Next, being illustrated using composition of the Figure 30 to air conditioner 200 with function.Comprising by thermal image acquisition unit 110 The thermal image of the Temperature Distribution of the people of acquisition is sent to operational part 230.Operational part 230 is according to defeated from thermal image acquisition unit 110 The thermal image entered determines the position of people 102, and infers warm-cold sensitivity.About the deduction of the warm-cold sensitivity carried out by operational part 230, It can be inferred as the first embodiment described above according to the difference value of human body temperature and ambient temperature, but as other methods, It can also be inferred according to the temperature of the hand of the people obtained from thermal image, nose, furthermore, it is not necessary to inferred according to thermal image, Here, this method is not defined.
Warm-cold sensitivity and position of the control unit 160 based on the people 102 inferred by operational part 230, control shutter 171, compression Machine 172 and fan 173, in order to cosily keep people 102 ambient temperature act.In addition to this, in present embodiment In, assign the warm-cold sensitivity of the people 102 inferred by operational part 230 to notification unit 210.Notification unit 210 includes set on air conditioner 200 The display unit of main body, such as LED.Warm-cold sensitivity of the LED based on the people 102 inferred by operational part 230 and be changed luminous Color.For example, being with green emitting if people 102 is comfortable, if being inferred as heat with red, orange if inferring in operational part 230 Deng warm colour shine, if be inferred as it is cold if shone with blue, cool colour as water colour.
In this way, people 102 can judge how air conditioner 200 is inferring the warm-cold sensitivity of oneself immediately.Thereby, it is possible to predict It will be carried out air conditioning strongly after this or because close to substantially comfortable the air conditioning after this subtracts It is weak, therefore have and no longer feel effect as uneasiness.
In addition, if being had differences in the warm-cold sensitivity for being shown in notification unit 210 and the warm-cold sensitivity oneself currently experienced In the case where, such as can be changed by that remote controler 291 shown in Figure 31 by the set point configuration part in operational part 230 The set point Tc (correction warm-cold sensitivity) of 135 settings.For example, in notification unit 210 just with green emitting (be inferred as comfortable) the case where Under, but when people 102 feels heat, " heat " of remote controler 291 this button can be pressed to indicate to correct.It is corresponding to the pushing of button Signal receiver 280 shown in the composition in Figure 32 that ground is sent from remote controler 291 is received as amendment receiving portion, is connect The signal of receipts is transferred to the set point configuration part 135 in operational part 230.For example, in the base as shown in the 1st embodiment In the case that the difference value of human body temperature and ambient temperature infers warm-cold sensitivity, it will be carried out slightly largerly as the set point Tc of threshold value It sets (change).In this way, control unit 160 is by reducing the temperature of compressor 172, to make one 102 ambient temperature It reduces, can be in comfortable.
As described above, by making the set point configuration part 135 in air conditioner 200 identify current sense with remote controler 291 etc. The warm-cold sensitivity being subject to is capable of providing optimized comfortable ambient enviroment to everybody.In addition, at this point, can also be such as the 1st As shown in Figure 9, the individual of determining setting simultaneously makes the setting of warm-cold sensitivity be stored in buffer 144 to embodiment, thereby, it is possible to Realize the optimized comfortable air conditioner for used individual.
