FIG. 3 is an example of a perspective view showing the indoor unit 2 according to Embodiment 1 of the present invention. Next, the indoor unit 2 will be described in detail. As shown in FIG. 3, the indoor unit 2 includes a housing 20 and a thermosensor 44. The housing 20 has a rectangular parallelepiped shape that is long in the width direction (arrow X direction), and includes a front panel 23, a side panel 24, a back panel 25, a top panel 27, and a bottom panel 26. The front panel 23 is a member disposed on the front surface facing the inside of the air conditioning target space R. The side panel 24 is a member that is attached to both end portions of the front panel 23 and disposed on both side surfaces. The back panel 25 is a member that faces the front panel 23 and is attached to the wall K of the air conditioning target space R. The top panel 27 is a member disposed on the top surface facing the ceiling T of the air conditioning target space R. The bottom panel 26 is a member that faces the top panel 27 and faces the floor of the air conditioning target space R. A room air inlet 21 extending in the width direction (arrow X direction) is formed in the center of the front panel 23, and room air extending in the width direction (arrow X direction) is formed in a part of the bottom panel 26. Is formed.

The indoor unit 2 is provided with an up / down wind direction plate 28 so as to close the outlet 22.

The thermosensor 44 is a thermopile in which the sensor portion is movable in the vertical direction (arrow Z direction), and FIG. 2 illustrates the case where the sensor portion of the thermosensor 44 is housed. Thus, since the indoor unit 2 has a rectangular parallelepiped shape that is long in the width direction (arrow X direction) and the blowout port 22 is formed in the lower panel 26, the blowout port 22 is viewed from the front when the operation is stopped. Is not visible. For this reason, the designability of the indoor unit 2 is improved. The indoor unit 2 does not have a rectangular parallelepiped shape that is long in the width direction (arrow X direction), and the shape of the indoor unit 2 is not limited as long as it has at least one suction port 21 and one outlet port 22. Absent.

FIG. 4 is an example of a side cross-sectional view showing the indoor unit 2 according to Embodiment 1 of the present invention. As shown in FIG. 4, the interior of the housing 20 is long in the width direction (arrow X direction) and is bent so as to face the front panel 23, the top panel 27, and the back panel 25. 4 is provided. In addition, an indoor blower 5 disposed so as to be covered with the indoor heat exchanger 4 is provided inside the housing 20. The top panel 27 is formed with a lattice-shaped suction port 21. A filter 37 is provided on the inner wall of the front panel 23 and the inner wall of the top panel 27. Here, the inner wall at the lower end of the rear panel 25 is referred to as a casing lower wall 39, and the inner wall extending from the lower end of the front panel 23 into the housing 20 is referred to as a casing upper wall 40. A drain pan 38 for collecting drain water falling from the indoor heat exchanger 4 is provided on the upper surface of the casing upper wall 40.

Further, inside the housing 20, there are an up / down wind direction plate support member 29, an up / down wind direction plate 28, a left / right wind direction plate 36, a first up / down auxiliary wind direction plate 31, a second up / down auxiliary wind direction plate support member 34, and a second. A vertical auxiliary wind direction plate 33 is provided. The vertical wind direction plate support member 29 is attached to the casing upper wall 40 and supports the vertical wind direction plate 28. As described above, the vertical wind direction plate 28 is for closing the outlet 22 and tilts in the vertical direction. Thereby, the direction of the up-down direction of the air which blows off from the blower outlet 22 changes. The left / right airflow direction plate 36 is attached to the casing upper wall 40 and swings in the left / right direction. Thereby, the direction of the left-right direction of the air which blows off from the blower outlet 22 changes.

The first vertical auxiliary wind direction plate 31 is attached to the casing upper wall 40, and swings in the vertical direction about the first vertical auxiliary wind direction plate shaft 32. Thereby, the direction of the up-down direction of the air which blows off from the blower outlet 22 changes. The second vertical auxiliary wind direction plate support member 34 is attached to the casing upper wall 40, supports the second upper auxiliary wind direction plate, and swings together with the second vertical auxiliary wind direction plate 33. The second vertical auxiliary wind direction plate 33 is attached to the casing upper wall 40 via the second vertical auxiliary wind direction plate support member 34 and is coaxial with the first vertical auxiliary wind direction plate shaft 32. It swings in the vertical direction around the wind direction plate shaft 35. Thereby, the direction of the up-down direction of the air which blows off from the blower outlet 22 changes. Note that the first vertical auxiliary wind direction plate 31 and the second vertical auxiliary wind direction plate 33 may be omitted.

Next, the air flow inside the indoor unit 2 will be described. Dust contained in air is removed by the filter 37 from room air sucked from the suction port 21 formed in the top panel 27 and the suction port 21 formed in the front panel 23. When the air from which the dust has been removed passes through the indoor heat exchanger 4, the air exchanges heat with the refrigerant flowing inside the indoor heat exchanger 4 and reaches the indoor blower 5. Here, when the air conditioner 1 is performing the cooling operation, the air is cooled, and when the air conditioner 1 is performing the heating operation, the air is heated. Then, the air that has reached the indoor blower 5 passes through the interior of the indoor blower 5 or a gap between the indoor blower 5 and the back panel 25 and flows between the casing lower wall 39 and the casing upper wall 40. . Here, the flow of air is adjusted in the horizontal direction by the left and right wind direction plates 36, and the flow in the vertical direction is adjusted by the vertical wind direction plates 28, the first vertical auxiliary wind direction plate 31 and the second vertical vertical wind direction plate 33. . Then, the air whose blowing direction is adjusted is blown forward or downward from the blowout port 22.

Next, the indoor control unit 50 will be described.

FIG. 5 is a top view showing an example of the air-conditioning target space R in the first embodiment of the present invention. As shown in FIG. 5, the air-conditioning target space R is, for example, a quadrangular room, which is 4.5 tatami mats, that is, a cubic room having a height of about 2.3 m and a height of about 2.3 m. It is assumed that there are two users in the air conditioning target space R and the vacuum cleaner is placed on the floor. Although the user and the vacuum cleaner move, the pillar, furniture, desk, and indoor unit 2 are immovable unless rearranged. The indoor unit 2 is provided on one wall K among the four walls of the air conditioning target space R. The indoor unit 2 is installed at a height of 1.8 m from the floor.

The camera 41 shoots the air-conditioning target space R, and is provided on the wall adjacent to the wall K where the indoor unit 2 is provided among the four walls of the air-conditioning target space R. The camera 41 may be provided on a wall facing the wall K where the indoor unit 2 is provided. The camera 41 is installed at a height of 1 m from the floor. The camera 41 is an inexpensive fixed focus camera that focuses on, for example, about 1 m to 10 m. The type of the camera 41 is determined in consideration of the size of the air-conditioning target space R and the depth of focus. The camera 41 has a function of enlarging or reducing the subject to be photographed. In this way, the camera 41 is installed in a place where the entire air-conditioning target space R, the indoor unit 2 and a person can shoot at a time.

Here, since it is necessary to photograph the entire person, the camera 41 may be installed at a height of about 0.8 m, which is about half the height of the person from the floor. Moreover, since it is necessary to photograph the indoor unit 2, the indoor unit 2 may be installed at a height of about 1 m, which is about half of the installation height of the indoor unit 2. The viewing angle of the camera 41 is 90 ° up and down and 90 ° left and right. The optical axis of the camera 41 is set parallel to the floor. Note that the optical axis of the camera 41 may be upward or downward as compared to the floor, but will be described in parallel here. In the present invention, the room, the installation position, the person position, and the camera angle will be described, but the present invention is not limited thereto. For example, the installation position may be 2 m, and the camera angle may be 120 °. The number of people may be one or two, and the position of the people does not depend on this example, and may be within the range reflected in the camera.

The two users are a child U1 and an adult U2, respectively. Child U1 is a 1 meter tall woman with a ponytail hairstyle and a ribbon attached to her hair. The adult U2 is a woman with a height of 1.6 m, and the hairstyle is cast hair and the headband is attached to the hair. The child U1 and the adult U2 are standing slightly apart. In addition, when image | photographed with the camera 41, the magnitude | size of a person changes with the position which exists in the air-conditioning object space R. FIG. Although there is generally a difference in height between a child and an adult, if the child is positioned extremely closer to the camera 41 than the adult, the child may be larger and the adult may be photographed smaller. Also, human hands, thumbs, feet, etc. are not labeled.

FIG. 6 is a block diagram showing the control device 42 according to Embodiment 1 of the present invention. The control device 42 is, for example, a server, and transmits air conditioning conditions to the indoor control unit 50 of the air conditioner 1. The control device 42 includes a storage unit 61, an image analysis unit 62, a setting unit 63, and an operation control unit 64. The control device 42 may be a personal computer or a smartphone. In this embodiment, it is assumed that the control device 42 is in the room where the indoor unit 2 is located or in the vicinity thereof. However, if the control device 42 is a portable terminal, the control device 42 may be controlled from outside the house when going out. . Further, the control device 42 may be a server that is physically distant from the room but connected on the network, such as installed in a completely different building from the house or located outside the country. However, as is the case inside the house, security must be particularly strict outside the house.

FIG. 7 is a table stored in the storage unit 61 according to Embodiment 1 of the present invention. The memory | storage means 61 has memorize | stored the table with which the attribute of the person who exists in the air-conditioning object space R and the operation | movement of the air conditioner 1 were matched. Here, the attributes of the person are, for example, sex and age. As shown in FIG. 7, the table includes items such as a recognition number for identifying a person, coordinates of a foot position, an estimated attribute, and a control determination result from room temperature. As the coordinates of the foot position, the vertical angle in the vertical direction and the horizontal angle in the horizontal direction are items. The estimated attributes include items such as height, weight, sex, and basal metabolism reference value.

At the table, the ratio of the wind of the air conditioner 1 is greater when the person is a man than when the person is a woman. In the table, the ratio of the air conditioner 1 to which the air is applied is greater when the person is a child than when the person is an adult. This is because basal metabolic standard values (kcal / kg / day) differ between men and women and children and adults. In males and females 18-29 years old, males have 24.0 kcal / kg / day and females 22.1 kcal / kg / day, and males have more basal metabolism, that is, calorific value from the body than females. For this reason, it is desirable that men are cooled more than women. Moreover, it is 44.3 kcal / kg / day in children 6 to 7 years old, and children have more basal metabolism than adults. For this reason, it is desirable that children are cooled more than adults. The source is Table 6 on page 66 of “Japanese Dietary Standards (2015 Version)” by the Ministry of Health, Labor and Welfare.

FIG. 8 is a background image taken by the camera 41 according to Embodiment 1 of the present invention. The image analysis means 62 analyzes the attribute and position of a person shown in the image taken by the camera 41. The accuracy of the person's position at the time of analysis is not so necessary. With the current technology, when sending wind, the wind cannot be sent at pinpoints in millimeters due to the airflow, and even if it is narrowed down, it becomes a wide range of 100 mm. Here, the image analysis means 62 acquires the position of the outlet 22 of the indoor unit 2 in advance. First, a background image in which the air-conditioning target space R when no one is present is acquired in advance before actual control. The control device 42 instructs the air conditioner 1 to “close the up-and-down wind direction plate 28”. Thereby, the up-and-down wind direction board 28 of the air conditioner 1 is closed. Then, the control device 42 instructs the camera 41 to “take a picture and send an image”. As a result, as shown in FIG. 8, a background image in a state where no person is present and the up-and-down wind direction plate 28 of the air conditioner 1 is closed is taken by the camera 41. Note that it is preferable that as many background images as possible be acquired in 24 hours. As a result, even if the state of the air-conditioning target space changes, for example, in the case of solar radiation or when a light is turned on at night, the image analysis means 62 can use a background image suitable at that time.

FIG. 9 is a background image taken by the camera 41 according to Embodiment 1 of the present invention. Next, the control device 42 instructs the air conditioner 1 to “open the up and down wind direction plate”. Thereby, the up-and-down wind direction board 28 of the air conditioner 1 is fully opened. Then, the control device 42 instructs the camera 41 to “take a picture and send an image”. As a result, as shown in FIG. 9, a background image in a state where no person is present and the up-and-down wind direction plate 28 of the air conditioner 1 is fully opened is captured by the camera 41. In the first embodiment, the air conditioning system 100 includes the router 43. In actual communication, when requesting image data from the control device 42, destination information “addressed to the IP address of the camera 41” is added to the information “send image data” to the router 43, and the received router 43 transmits information “send image data” to the camera 41. In the first embodiment, the above content will be described in a simplified manner to the content that the control device 42 instructs the camera 41 to “send image data”.

FIG. 10 is a difference image according to the first embodiment of the present invention. The image analysis means 62 obtains a difference between the background image shown in FIG. 8 and the background image shown in FIG. Specifically, the image analysis means 62 takes the difference between the values of each pixel of the two image data. Thereby, as shown in FIG. 10, the difference image extracted by highlighting (shaded part) the outlet 22 of the indoor unit 2 is acquired.

The image analysis means 62 acquires the coordinates of the extracted one end A1 and the other end A2 in the width direction of the outlet 22 with the position of the camera 41 as the origin, and obtains the coordinates of the center position O of the outlet 22. The coordinates of A1 are the vertical angle α _a1 = 32 ° and the left and right angles β _a1 = −40 °, and the coordinates of A2 are the vertical angle α _a2 = 20 ° and the left and right angles β _a2 = −22 °. Further, the installation height of the indoor unit 2 is L _a = 1.8 m, and the installation height of the camera 41 is L _c = 1 m. The coordinates x _a , y _a , and z _a of the center position O of the outlet 22 are obtained from the following formulas (1), (2), and (3).

[Equation 1]
x _a = y _a × tan ((β _a2 + β _a1 ) / 2) (1)

[Equation 2]
y _a = z _a / tan ((α _a2 + α _a1 ) / 2) (2)

[Equation 3]
z _a = L _a −L _c (3)

From formula (3), z _a = 1.8-1 = 0.8.

FIG. 11 is an image taken by the camera 41 according to Embodiment 1 of the present invention. The image analysis unit 62 acquires an image of the air-conditioning target space R when a person is present during actual control. The control device 42 instructs the air conditioner 1 to “open the up and down wind direction plate”. Thereby, the up-and-down wind direction board 28 of the air conditioner 1 is fully opened. Then, the control device 42 instructs the camera 41 to “take a picture and send an image”. Thereby, as shown in FIG. 11, the up-and-down wind direction plate 28 of the air conditioner 1 is fully opened, and an image of a person is taken by the camera 41.

FIG. 12 is a difference image according to the first embodiment of the present invention. The image analysis means 62 calculates the difference between the background image shown in FIG. 9 and the image shown in FIG. Specifically, the image analysis means 62 takes the difference between the values of each pixel of the two image data. Thereby, as shown in FIG. 12, the difference image extracted by highlighting the moving objects not shown in the background images such as the child U1, the adult U2, and the vacuum cleaner U9 is acquired. Note that the difference image may be acquired from the image shown in FIG. 11 and the background image shown in FIG. 8, or may be acquired from the image shown in FIG. 11 and the difference image shown in FIG.

The image analysis means 62 analyzes the image shown in FIG. 12 and recognizes a person. The image analysis unit 62 searches for a face in the image by collating, for example, the image with the face pattern stored in the storage unit 61 in advance. This is called pattern matching. At this time, the child U1 and the adult U2 whose face is recognized are listed as human candidates, and the vacuum cleaner U9 whose face is not recognized is excluded from the human candidates. In the human recognition, the case where the face is searched and the body is sequentially recognized is illustrated. However, the entire body may be searched, or each part of the face, eyes, nose, and mouth may be searched. May be.

FIGS. 13 and 14 are explanatory diagrams showing the face model in Embodiment 1 of the present invention. There are a large number of face models used for pattern matching because they vary widely depending on the age, gender, and direction of a person. The face model has at least “attribute (age, gender)” and “direction (direction of the face viewed from the front such as a side face)”. As shown in FIG. 13, a plurality of face models are created even if the gender and age match, such as female 20s A, female 20s B, and females 20s C. Furthermore, as shown in FIG. 14, a plurality of face models are also used depending on the angle, such as an angle 0 ° from the front, an angle 10 °, an angle 30 °, and an angle 90 °.

The face model is created assuming a face when the distance from the camera 41 is a predetermined distance, for example, 1 m. Here, although the positions of eyes and nose do not change so much depending on gender, the positions of eyes and nose change greatly depending on the age. This is because, in general, the size of the eyeball is almost the same between the child and the adult even if the size of the face changes, so the child looks relatively larger than the adult. For this reason, separate face models are created for children and adults. Here, since the pattern matching is performed by the control device 42, the face model only needs to be stored in the storage unit 61.

The face model is mainly registered for the eyes, nose, mouth and the vicinity of the lower jaw. In the face model, ears and hair are not registered. This is because hair and hairstyle vary greatly from person to person. The child U1 shown in FIG. 12 has tied hair, but may have unraveled hair. In addition, the ears may be hidden in the hair. The adult U2 shown in FIG. 12 may slightly see the ear, but may disappear if the hairstyle changes. When a person wears a mask or sunglasses, pattern matching may not be performed correctly. In addition, pattern matching may not be performed correctly even when a person is turned away.

FIG. 15 is an explanatory diagram showing a face model according to Embodiment 1 of the present invention. As shown in FIG. 15, in pattern matching, a search is performed while a face model as a comparison image is enlarged or reduced by an image analysis unit 62 in accordance with the size of a human face in the image. Further, since the face may be lying down, the search is performed while the face model is rotated at any time. Pattern matching is performed on the entire screen of the image. In the first embodiment, pattern matching is performed on the difference image shown in FIG. As described above, the pattern matching is performed on the difference image with the background image acquired in advance, thereby reducing the number of pixels on which the pattern matching is performed, and thus the processing load on the control device 42 is reduced.

FIG. 16 is a graph showing the face recognition rate in Embodiment 1 of the present invention. In FIG. 16, the horizontal axis represents the horizontal angle (α) and the vertical angle (β), and the vertical axis represents the face recognition rate. The matching rate with the face model is calculated by pattern matching. Then, the face model is dispersed like a terrain on the screen. In the image shown in FIG. 12, since there are two people, as shown in FIG. 16, there are two peaks, and the face can be determined. In the image shown in FIG. 12, the position of the face of the child U1 is in the vicinity of α _h1 = −10 ° and β _h1 = −10 °. The position of the face of the adult U2 is α _h2 = + 15 ° and β _h2 = + 3 °. Based on attribute information attached to a face model with a high matching rate, at least a child or an adult can be estimated among the attributes of a person having a matching face. Thereby, the child U1 is estimated as a child, and the adult U2 is estimated as an adult.

Based on the enlargement ratio of the face model, the distance from the camera 41 to the head is obtained. Since the distance from the camera 41 to the face at the time of creating the face model is 1 m, for example, when pattern matching is performed with a magnification ratio of 0.9 times the face model of the child U1, the distance y _h1 from the camera 41 to the face is 1 m / 0.9 = 1.11 m. After the distance y _h1 from the camera 41 to the face is obtained, the head positions x _h1 and z _h1 of the child U1 are obtained from the following equations (4) and (5).

[Equation 4]
x _h1 = y _h1 × tan (β _h1 ) (4)

[Equation 5]
z _h1 = y _h1 × tan (α _h1 ) (5)

Further, the positions x _h2 and z _h2 of the face of the adult U2 can be obtained from the following formulas (6) and (7).

[Equation 6]
x _h2 = y _h2 × tan (β _h2 ) (6)

[Equation 7]
z _h2 = y _h2 × tan (α _h2 ) (7)

FIG. 17 is an explanatory diagram showing a body model according to Embodiment 1 of the present invention. Next, the search of the whole body after face recognition will be described. First, a case where a person is facing the front as shown in FIG. 17 will be described. For a body other than the face, pattern matching is performed based on a previously recognized part. For example, it is normally impossible for the face and neck to be extremely separated or bent, so the angle range is within about 45 ° starting from the lower end of the lower jaw. Further, since the face size is known to some extent by the face recognition, the size of the neck can be estimated to some extent. For this reason, even if pattern matching of the neck model after the neck is performed, the number of times of matching is small, and the direction and the enlargement ratio are limited.

Then, pattern matching is performed in the order of neck, chest, abdomen, thigh, knee and foot. Note that the abdomen, thighs, and the like change depending on clothes, and therefore, complementation processing or correction processing is performed. In addition, since the breasts differ by gender, a male breast model and a female breast model are created. When the position of the foot is obtained, the approximate position of the contact point of each part is calculated based on the magnification of the model, and the height is estimated. When the foot is specified, angles α _u1 , β _u1 , α _u2 , β _{u2 and the} like on the camera 41 at that time are obtained. In addition, age and weight are estimated based on height, and a basal metabolic rate is obtained. Further, since pattern matching is sequentially performed, postures such as standing, sitting, and lying are estimated.

FIG. 18 is an explanatory diagram showing a body model according to Embodiment 1 of the present invention. As shown in FIG. 18, when a person is facing sideways, pattern matching is performed in the order of neck, chest, abdomen, thighs, knees, and feet as in the case of facing the front.

Assuming that the installation height of the camera 41 is L _c = 1 m, the coordinates x _u1 , _{yu 1} , z _u1 of the foot position of the child U1 can be obtained from the following equations (8), (9), and (10).

[Equation 8]
x _u1 = y _u1 × tan (β _u1 ) (8)

[Equation 9]
y _u1 = −z _u1 / tan (α _u1 ) (9)

[Equation 10]
z _u1 = −L _c (10)

Further, the coordinates x _u2 , y _u2 , and z _u2 of the position of the foot of the adult U2 are obtained from the following formulas (11), (12), and (13).

[Equation 11]
x _u2 = y _u2 × tan (β _u2 ) (11)

[Equation 12]
y _u2 = −z _u2 / tan (α _u2 ) (12)

[Equation 13]
z _u2 = −L _c (13)

The image analysis means 62 calculates the position of the person when viewed from the indoor unit 2. The left and right angles of the foot position of the child U1 viewed from the indoor unit 2 are the left and right angles γ _u1 = atan ((y _a −y _u1 ) / (x _a −x _u1 )), and the vertical angle is the vertical angle θ _u1 = atan ((z _a −z _u1 ) / (x _a −x _u1 )). The left and right angles of the foot position of the adult U2 viewed from the indoor unit 2 are the left and right angles γ _u2 = atan ((y _a −y _u2 ) / (x _a −x _u2 )), and the vertical angle is the vertical angle θ _u2 = atan ((z _a −z _u2 ) / (x _a −x _u2 )).

The setting unit 63 operates the air conditioner 1 based on the attribute of the person analyzed by the image analysis unit 62, the table stored in the storage unit 61, and the position of the person analyzed by the image analysis unit 62. Is set. Based on the analysis result of the image analysis means 62, the setting means 63 fills the blanks in the table shown in FIG. 7, and sets the operation of the air conditioner 1 so as to match the attributes. For example, when the recognition number is the child U1, the vertical angle of the foot position is −45 °, the horizontal angle is −5 °, the height is 1000 mm, the weight is 22 kg, the gender is unknown, the basal metabolism reference value is 41.9 kcal / kg / day, Control judgment from temperature is wind blow and air volume strong. When the identification number is adult U2, the vertical angle of the foot is −35 °, the horizontal angle is + 5 °, the height is 1600 mm, the weight is 53 kg, the female is gender, the basal metabolic standard is 21.7 kcal / kg / day, The control determination is windbreak.

The operation control unit 64 operates the air conditioner 1 with the operation set by the setting unit 63. Specifically, the operation control means 64 instructs the indoor unit 2 to “set the wind direction to the left / right angle γ _u1 and the vertical angle θ _u1 ”. Thus, the indoor unit 2 causes the vertical wind direction plate 28, the first vertical auxiliary wind direction plate 31, the second vertical auxiliary wind direction plate 33, and the left and right wind direction plates to send wind to the left and right angle γ _u1 and the vertical angle θ _u1. 36 is adjusted. Thereby, a wind is sent to the child's U1 step. In addition, the operation control means 64 instructs the indoor unit 2 to “set the wind direction to the left / right angle γ _u2 and the up / down angle θ _u2 ”. Thereby, the indoor unit 2 sends the wind to the left and right angle γ _u2 and the up and down angle θ _u2 so that the up and down wind direction plate 28, the first up and down auxiliary wind direction plate 31, the second up and down auxiliary wind direction plate 33, and the left and right wind direction plate. 36 is adjusted. Thereby, the wind is sent to the foot of the adult U2. In addition, when the wind direction of the indoor unit 2 can be divided into two directions, the wind can be sent to any of the feet of the child U1 and the adult U2. Further, the operation control means 64 may instruct the indoor unit 2 to send wind to the face position.

Next, the operation mode of the air conditioner 1 will be described. The air conditioner 1 has a cooling operation and a heating operation as operation modes. In the cooling operation, the refrigerant flows in the order of the compressor 8, the flow path switching unit 9, the outdoor heat exchanger 6, the expansion unit 10, and the indoor heat exchanger 4 (solid arrow in FIG. 2). Is cooled by heat exchange with the refrigerant. In the heating operation, the refrigerant flows in the order of the compressor 8, the flow path switching unit 9, the indoor heat exchanger 4, the expansion unit 10, and the outdoor heat exchanger 6 (broken arrows in FIG. 2). Is heated by exchanging heat with the refrigerant.

Next, the operation of each operation mode of the air conditioner will be described. First, the cooling operation will be described. In the cooling operation, the refrigerant sucked into the compressor 8 is compressed by the compressor 8 and discharged in a high-temperature and high-pressure gas state. The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 8 passes through the flow path switching unit 9 and flows into the outdoor heat exchanger 6. In the outdoor heat exchanger 6, the outdoor air blown by the outdoor fan 7. Heat exchanges with air and condensates. The condensed refrigerant in the liquid state flows into the expansion unit 10 and is expanded and depressurized in the expansion unit 10 to be in a gas-liquid two-phase state. Then, the gas-liquid two-phase refrigerant flows into the indoor heat exchanger 4, and in the indoor heat exchanger 4, heat is exchanged with indoor air to evaporate. At this time, the room air is cooled and cooling is performed. The evaporated refrigerant in the gas state passes through the flow path switching unit 9 and is sucked into the compressor 8.

Next, the heating operation will be described. In the heating operation, the refrigerant sucked into the compressor 8 is compressed by the compressor 8 and discharged in a high-temperature and high-pressure gas state. The high-temperature and high-pressure gas refrigerant discharged from the compressor 8 passes through the flow path switching unit 9 and flows into the indoor heat exchanger 4, and the indoor heat exchanger 4 blows the indoor air blown by the indoor fan 5. Heat exchanges with air and condensates. At this time, room air is warmed and heating is performed. The condensed refrigerant in the liquid state flows into the expansion unit 10 and is expanded and depressurized in the expansion unit 10 to be in a gas-liquid two-phase state. Then, the gas-liquid two-phase refrigerant flows into the outdoor heat exchanger 6, and in the outdoor heat exchanger 6, heat is exchanged with outdoor air to evaporate. The evaporated refrigerant in the gas state passes through the flow path switching unit 9 and is sucked into the compressor 8.

FIG. 19 is a flowchart showing the operation of the air-conditioning system 100 according to Embodiment 1 of the present invention. Next, operation | movement of the control apparatus 42 of the air conditioning apparatus which concerns on this Embodiment 1 is demonstrated. As shown in FIG. 19, first, background images shown in FIGS. 8 and 9 are acquired in advance before actual control (step ST1). Next, a difference image (FIG. 10) between the background image shown in FIG. 8 and the background image shown in FIG. 9 is acquired (step ST2). Then, the coordinates x _a , y _a , z _a of the center position O of the outlet 22 of the indoor unit 2 are obtained (step ST3). Then, it is determined whether or not the indoor unit 2 is activated (step ST4). When the indoor unit 2 is not activated (No in step ST4), the process returns to step ST1.

On the other hand, when the indoor unit 2 is activated (Yes in step ST4), an image shown in FIG. 11 where a person is present is acquired (step ST5). Then, a difference image (FIG. 12) between the background image shown in FIG. 8 or FIG. 9 and the image shown in FIG. 11 is acquired (step ST6). Next, face pattern matching is performed (step ST7). Then, pattern matching of the body up to the foot is performed (step ST8). Here, the coordinates x _u , _yu and z _u of the position of the person's foot are obtained (step ST9). Thereafter, the coordinates of the foot position are converted into position coordinates when viewed from the indoor unit 2 (step ST10). And the wind direction of the indoor unit 2 is adjusted and a wind is sent to the position of a step (step ST11). Thereafter, the process returns to step ST4.

According to the first embodiment, the control device 42 includes the storage unit 61 that stores a table in which human attributes and the operations of the air conditioner 1 are associated with each other. For this reason, in the air conditioner 1, the operation | movement adapted to the attribute of the person who is in a room is performed. Therefore, in the air conditioning system 100, an appropriate air conditioning operation is performed on the user without cost.

Conventionally, a system in which a camera 41 installed in a store, a data processing device, and air conditioning equipment are connected via a network is known. However, conventional systems do not consider how the wind direction is controlled by age and gender. Further, the conventional system does not obtain the position of the person based on the image. With this, the wind suitable for the user is not sent. Conventionally, a technique for adjusting the capacity of an air conditioner based on the number of occupants is known, but no consideration is given to human attributes. Furthermore, conventionally, a technique for determining a comfort index value from a predicted average report (PMV) and an activity amount is known, but no consideration is given to human attributes. On the other hand, in the first embodiment, the control device 42 includes a storage unit 61 that stores a table in which human attributes and operations of the air conditioner 1 are associated with each other. For this reason, in the air conditioner 1, the operation | movement adapted to the attribute of the person who is in a room is performed.

Further, for the recognition of a human face, pattern matching is generally used in which a matching rate is determined by comparing with a plurality of face models prepared in advance. Since face models vary widely depending on the age, gender, and direction of a person, there are numerous models. Pattern matching is performed by matching with all face models at all pixels in the image. Further, since the size of the face in the image varies depending on the distance, it is necessary to enlarge or reduce the face model. For example, if pattern matching is performed by 1000 face models, 1000 pixel × 1000 pixel images, and 10 enlargements / reductions, it is necessary to repeat 1 billion times. If pattern matching is performed in the indoor control unit 50 of the indoor unit 2, an extremely expensive control circuit is required, and the manufacturing cost of the indoor unit 2 increases.

In contrast, in the first embodiment, the control device 42 connected to the air conditioner 1 via a network performs pattern matching. Then, the air conditioner 1 only needs to change the wind direction and blow air based on the processing result of the control device 42. For this reason, the control processing of the air conditioner 1 is simplified. Therefore, an expensive control circuit is not required for the air conditioner 1 and the camera 41, and the cost can be reduced.

Furthermore, the control device 42 recognizes the gender and the age based on the height as a human attribute. For example, the control device 42 recognizes an adult male, an adult female, and a child. When a tag such as an adult male is attached to the face model, the control device 42 can recognize it as an adult male alone. Moreover, since a breast pattern changes with sex, it can also distinguish sex. Thereby, the blowing of the wind in the attribute of the person is realized. Based on the table shown in FIG. 7 and various parameters such as the current room temperature, whether the person is hot or cold is determined individually. Thereby, the optimal wind can be sent for every person. Therefore, user comfort is improved.

(First modification)
In the first modification, the camera 41 has an autofocus function for automatically focusing on a person, and the image analysis unit 62 measures the distance from the focal length of the camera 41 to the person shown in the image. It has a function. The image analysis means 62 calculates the face position α _h1 = −10 ° and β _h1 = −10 ° based on the image shown in FIG. Then, the control device 42 instructs the camera 41 to “focus on the position of α _h1 = −10 °, β _h1 = −10 ° and measure the distance”. The camera 41 opens the diaphragm at the maximum and adjusts the lens so that the focus is on the face position α _h1 = −10 ° and β _h1 = −10 °. Then, the in-focus distance, for example, 1 m is acquired. Thereafter, the camera 41 transmits information “distance is 1 m” to the control device 42. Thereby, even if recognition up to the position of the foot is hindered by an obstacle or the like, the distance from the camera 41 to the person can be measured.

When the camera 41 is out of focus, the image is blurred. This is remarkable when the aperture of the camera 41 is opened. If the user tries to focus over a wide range of distances, the aperture needs to be fairly narrow. That is, when the aperture is opened, the focus is on only a predetermined range of distance. In the first modification, the distance is measured using this. As described above, the air conditioning system 100 may directly acquire the distance from the camera 41 to the face. In addition, when it cannot focus to a fine coordinate, it may focus on discretely and the control apparatus 42 may calculate a position suitably. For example, the control device 42 can “focus on the position of 0.5 m and measure the distance”, “focus on the position of 1 m and measure the distance”, and “focus on the position of 1.5 m. ”And measure the distance” may be issued, and the position may be calculated based on a plurality of images. In this case, if there is a recognition means, the position of an object such as a vacuum cleaner or the size of a room can be measured. Furthermore, the air conditioning system 100 may include a distance measuring instrument that measures a distance in the vicinity of the camera 41. Also in this case, the same effect as that of the first embodiment in which the distance is measured based on the enlargement ratio is obtained. The rangefinder may be the camera 41 and the image analysis means 62.

(Second modification)
FIG. 20 is a temperature distribution image photographed by the thermosensor 44 in the second modification of the first embodiment of the present invention. In the second modified example, the thermosensor 44 is used to recognize that the human figure shown in the image is a person. The thermosensor 44 captures the temperature distribution of the air conditioning target space R and acquires a temperature distribution image. The temperature distribution image is a thermal image. As described above, the thermo sensor 44 is provided on the lower surface adjacent to the outlet 22 of the indoor unit 2, and the sensor main body projects from the lower surface of the indoor unit 2 and faces forward. That is, the direction in which the air-conditioning target space R is viewed from the air outlet 22 and the direction in which the air-conditioning target space R is viewed from the thermosensor 44 are substantially the same although there is a slight error. After the face recognition is completed, the image analysis unit 62 calculates the position of the person when viewed from the indoor unit 2. Then, the control device 42 instructs the thermosensor 44 of the indoor unit 2 to “send the temperature distribution image”. The thermo sensor 44 images the temperature distribution. Thereby, as shown in FIG. 20, a temperature distribution image in which a portion having a high temperature is highlighted is acquired.

Note that the thermosensor 44 may capture a temperature distribution in advance. In winter, the human temperature is higher than the clothing temperature. Therefore, the temperature of the part where the skin is exposed (filled part in FIG. 20) is high. Note that the shaded portion 2v at the top of the temperature distribution image shown in FIG. 20 is due to the heat generated by the indoor unit 2. The image analysis means 62 acquires the temperatures of the left and right angles γh and the vertical angle θh from the indoor unit 2 at the position estimated to be a face in the temperature distribution image. Generally, the vicinity of the face is about 36 ° C. When the acquired temperature is around 36 ° C., the image analysis means 62 recognizes that the face is a human face. Accordingly, it is possible to prevent a life-size poster depending on the ambient temperature, a person appearing on a television or a PC monitor, a robot with a human face, and the like from being mistaken as a human face. Note that the camera 41 having a function of capturing a temperature distribution image may be used, but the camera 41 having a function of capturing a temperature distribution image is expensive, and thus the thermosensor 44 of the indoor unit 2 can be used. preferable.

Embodiment 2. FIG.
FIG. 21 is a diagram showing the air conditioning target space R in the second embodiment of the present invention. The second embodiment is different from the first embodiment in that the blowing direction of the blowing port 22 of the indoor unit 2 matches the optical axis of the camera 41. In the second embodiment, the same parts as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The description will focus on differences from the first embodiment.

As shown in FIG. 21, the camera 41 is attached directly below the indoor unit 2 in the wall K to which the indoor unit 2 is attached. That is, the optical axis of the camera 41 coincides with the blowing direction of the blowing port 22 of the indoor unit 2. The height _{L c} installation of the camera 41 is 1 m, the height _{L a} installation of the indoor unit 2 is 1.8 m.

FIG. 22 is a background image taken by the camera 41 according to Embodiment 2 of the present invention. The image analysis means 62 acquires in advance a background image in which the air-conditioning target space R is photographed when there is no person before actual control. The control device 42 instructs the camera 41 to “take a picture and send an image”. Thereby, as shown in FIG. 22, a background image without a person is taken by the camera 41. In the air-conditioning target space R, a dresser is placed. Here, the indoor unit 2 is not shown in the background image. The camera 41 and is attached just below the indoor unit 2, the coordinate _{x c,} y _{c, z} c of the position of the camera _{41, x c = x a, y} c = y a, z c = z _a −L _c + L _a . Thus, since the position of the blowout port 22 of the indoor unit 2 and the optical axis of the camera 41 coincide, acquisition of the position of the blowout port 22 is unnecessary.

FIG. 23 is an image taken by the camera 41 according to the second embodiment of the present invention. The image analysis unit 62 acquires an image of the air-conditioning target space R when a person is present during actual control. The control device 42 instructs the air conditioner 1 to “open the up and down wind direction plate”. Thereby, the up-and-down wind direction board 28 of the air conditioner 1 is fully opened. Then, the control device 42 instructs the camera 41 to “take a picture and send an image”. Thereby, as shown in FIG. 23, an image of a person is taken by the camera 41.

FIG. 24 is a difference image according to the second embodiment of the present invention. The image analysis means 62 calculates the difference between the background image shown in FIG. 22 and the image shown in FIG. Specifically, the image analysis means 62 takes the difference between the values of each pixel of the two image data. As a result, as shown in FIG. 24, a moving image that is not shown in the background image such as the child U1, the adult U2, and the vacuum cleaner U9 is highlighted and extracted, and a difference image from which the immovable chiffon is removed is acquired. The

Thereafter, face pattern matching and pattern matching up to the foot are performed, and the coordinates of the foot position are acquired. The image analysis means 62 calculates the position of the person when viewed from the indoor unit 2. The left and right angles of the foot position of the child U1 viewed from the indoor unit 2 are the left and right angles γ _u1 = atan ((x _a −x _u1 ) / (y _a −y _u1 )), and the vertical angle is the vertical angle θ _u1 = atan ((z _a −z _u1 ) / (y _a −y _u1 )). The left and right angle γ _u1 when viewed from the indoor unit 2 matches the left and right angle β _u1 when viewed from the camera 41, and γ _u1 = β _u1 . The left and right angles of the foot position of the adult U2 viewed from the indoor unit 2 are the left and right angles γ _u2 = atan ((x _a −x _u2 ) / (y _a −y _u2 )), and the vertical angle is the vertical angle θ _u2 = atan ((za−z _u2 ) / (ya−y _u2 )). The left and right angle γ _u2 when viewed from the indoor unit 2 matches the left and right angle β _u2 when viewed from the camera 41, and γ _u2 = β _u2 . Thereafter, the operation of the air conditioner 1 is set by the setting means 63, and the operation of the air conditioner 1 is controlled by the operation control means 64.

FIG. 25 is a flowchart showing the operation of the air-conditioning system 100 according to Embodiment 2 of the present invention. Next, operation | movement of the control apparatus 42 of the air conditioning apparatus which concerns on this Embodiment 2 is demonstrated. As shown in FIG. 25, first, the background image shown in FIG. 22 is acquired in advance before actual control (step ST21). Next, it is determined whether or not the indoor unit 2 is activated (step ST22). When the indoor unit 2 is not activated (No in step ST22), the process returns to step ST21. On the other hand, when the indoor unit 2 is activated (Yes in step ST22), an image shown in FIG. 23 where a person is present is acquired (step ST23). Then, a difference image (FIG. 24) between the background image shown in FIG. 22 and the image shown in FIG. 23 is acquired (step ST24). Next, face pattern matching is performed (step ST25). Then, pattern matching of the body up to the foot is performed (step ST26). Here, the coordinates x _u , _yu and z _u of the position of the person's foot are obtained (step ST27). Thereafter, the coordinates of the foot position are converted into position coordinates when viewed from the indoor unit 2 (step ST28). And the wind direction of the indoor unit 2 is adjusted and a wind is sent to the position of a step (step ST29). Thereafter, the process returns to step ST22.

According to the second embodiment, since the position of the air outlet 22 of the indoor unit 2 matches the optical axis of the camera 41, the position of the air outlet 22 need not be acquired. Further, the left-right direction of the indoor unit 2 matches the left-right direction of the image. For this reason, the left and right angles when viewed from the indoor unit 2 coincide with the left and right angles when viewed from the camera 41. Therefore, it is not necessary to convert the left and right angles. Note that this also eliminates the need to convert the two left and right angles when the wind direction of the indoor unit 2 can be divided into two directions. Therefore, in the second embodiment, in addition to the effects obtained in the first embodiment, the processing burden on the control device 42 is reduced. The camera 41 is not limited to being directly below the indoor unit 2, but may be attached to the right side of the indoor unit 2 or the left side of the indoor unit 2, and the front panel 23, the side panel 24, or the top panel of the indoor unit 2. 27 may be attached. It is only necessary to know the positional relationship between the outlet 22 of the indoor unit 2 and the camera 41.

Also in the second embodiment, the distance may be measured using the autofocus function as in the first modification of the first embodiment, or the distance may be measured using a distance measuring instrument. Also in the second embodiment, a human face may be recognized by the thermosensor 44 as in the second modification of the first embodiment.

Embodiment 3 FIG.
FIG. 26 is a side view showing the air-conditioning target space R in the third embodiment of the present invention. The third embodiment is different from the first embodiment in that a user's individual is specified. In the third embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. The description will focus on differences from the first embodiment.

In the third embodiment, the control device 42 registers the individual face in the storage means 61 in advance in order to identify the individual user of the air-conditioning target space R. The registration target is, for example, a family in the air conditioning target space R. At that time, the air conditioner 1 is not used. As shown in FIG. 26, the control device 42 instructs, for example, a child U <b> 1 among the users to stand in front of the camera 41. The standing position is a predetermined distance 1 m when the face model is created. Thus, the distance can be measured using the enlargement / reduction ratio. The control device 42 gives an instruction such as “Please lower your neck a little”, “Turn right a little”, “Please lie down”, etc. to the child U1. Then, the control device 42 instructs the camera 41 to “take a picture and send an image”. Accordingly, the camera 41 captures the face of the child U1 and transmits the image to the control device 42.

The control device 42 recognizes the face, trims the matched area, and creates a new face model dedicated to the child U1. This series of operations is repeated a predetermined number of times, and when all the conditions are met, a name is given to the face model group, and the storage unit 61 stores the face model group. Also in the adult U2, the storage unit 61 stores the face model group in the same manner as the child U1.

FIG. 27 is a table stored in the storage unit 61 according to Embodiment 3 of the present invention. As shown in FIG. 27, the table is a table in which the faces of people in the air-conditioning target space R previously captured by the camera 41 are associated with the attributes of people in the air-conditioning target space R. . Thereby, an individual can be specified. The names are child U1 SAE and adult U2 ANZU. The table also stores personal preferences. For example, if the preference of the child U1 is assumed to be hot, the air conditioner 1 is controlled so that the wind can be more easily hit. Further, if the taste of the adult U2 is assumed to be cold, the air conditioner 1 is controlled so that the wind is less likely to hit. Thereby, even if a preference differs between individuals, in the same air-conditioning object space R, a comfortable environment can be respectively obtained.

FIG. 28 is a flowchart showing the operation of the air-conditioning system 100 according to Embodiment 3 of the present invention. Next, operation | movement of the control apparatus 42 of the air conditioning apparatus which concerns on this Embodiment 3 is demonstrated. As shown in FIG. 28, first, the child U1 stands in front of the camera 41 (step ST31). Next, the control device 42 instructs the child U1 to take a shooting posture (step ST32). Then, the face is recognized based on the image photographed by the camera 41, and a part where the face is recognized is created as a new face model (step ST33). Then, it is determined whether or not a face model has been created for all postures (step ST34). When the face model creation work in another posture remains (No in step ST34), the process returns to step ST32. When the face model creation work for all postures is completed (Yes in step ST34), the face model is assigned a name and stored (step ST35).

According to the third embodiment, in the face pattern matching, the registered child U1 and registered adult U2 face models are preferentially used. Since the dedicated face model is a model of the person, the face recognition rate is improved. Thereby, an individual can be specified. In addition, it is possible to perform comfortable air conditioning for an individual reflecting the personal taste. For example, if the child U1 is hot, the wind is intensively sent in the summer, and if the adult U2 is cold, the wind is avoided in the summer.
