  As a means for evaluating a feeling of comfort by air conditioning, an index for estimating a human thermal feeling from an environmental factor related to thermal temperature such as a room temperature or humidity has been used. In general, in order to estimate the thermal sensation of a person, the comfortable feeling is estimated by a measuring device that imitates the shape and body temperature of the person.

  For example, the means for solving the abstract of Patent Document 1 includes: “The comfort evaluation device is connected to a thermal environment detection means 10 for detecting a thermal environment element around a human body installed in an automobile interior or the like, and a thermal environment detection means 10. The human body heat model 11 for estimating the skin temperature of the human body face based on the signal output from the thermal environment detecting means, the face skin temperature estimated by the human body heat model 11 and the rate of change thereof are hot, The warmth estimation means 12 for estimating the whole body warm feeling such as cold, and the comfort feeling for quantitatively estimating the level of comfort such as uncomfortable or comfortable based on the relationship between the whole body warm feeling and the comfort. The estimation means 13 is provided. "

  Paragraph 0018 of Patent Document 1 states that “the human body thermal model is a system in which a human body is divided into parts such as a face part, an arm part, a torso part, and a leg part, and the amount of clothes, activity level, sweating, blood Estimate the thermal sensation based on the thermal environment element detected by the thermal environment detection means by calculating the thermal balance between the human body and the environment, taking into account the characteristics of human body temperature regulation reaction such as flow It is a mathematical model for calculating skin temperature, which is physiological information, for each part of the human body. "

  Hereinafter, examples for carrying out each invention will be described in detail with reference to the drawings.

  FIG. 1 is a front view of the indoor unit 100, the outdoor unit 200, and the remote controller Re of the air conditioner A in the present embodiment.

  As shown in FIG. 1, the air conditioner A includes an indoor unit 100, an outdoor unit 200, and a remote controller Re. The outdoor unit 200 includes a compressor, an outdoor heat exchanger, an outdoor blower, a four-way valve, and an expansion valve. The indoor unit 100 includes an indoor heat exchanger and an indoor blower. The indoor unit 100 and the outdoor unit 200 are connected by a refrigerant pipe 300, and air conditioning of the room in which the indoor unit 100 is installed can be performed by a known refrigerant cycle. The indoor unit 100 and the outdoor unit 200 transmit and receive information to and from each other via a communication cable (not shown).

  The remote controller Re is operated by the user and transmits an infrared signal to the remote controller transmission / reception unit Q of the indoor unit 100. The contents of the infrared signal are commands such as an operation request, a change in set temperature, a timer, an operation mode change, and a stop request. The air conditioner A performs air conditioning operations such as a cooling mode, a heating mode, and a dehumidifying mode based on these infrared signal commands. Moreover, the indoor unit 100 transmits data such as room temperature information, humidity information, and electricity bill information from the remote control transmission / reception unit Q to the remote control Re.

  In addition, an imaging unit 121 and a thermopile 122 (non-contact heat sensor) are installed close to each other at the center lower portion of the indoor unit 100.

  The imaging unit 121 can image a room in a band including a visible light band and a partial band of infrared light. The thermopile 122 is a non-contact type thermal sensor, and acquires the detected temperature distribution as a thermal image. Thereby, since the imaging unit 121 and the thermopile 122 are close to each other, the captured image by the imaging unit 121 and the thermal image by the thermopile 122 can be associated with each other. The imaging unit 121 is arranged to capture an image of the air-conditioned room.

  The arrangement of the thermopile 122 and the imaging unit 121 may be set according to the image detection method and the detection target, the specification of the imaging unit 121, and the like.

  Details of the imaging unit 121 and the thermopile 122 will be described later.

  FIG. 2 is a side sectional view of the indoor unit 100 in each embodiment. FIG. 3 is a perspective view of the indoor unit in each embodiment.

  As shown in FIG. 2, the housing base 101 of the indoor unit 100 houses internal structures such as the indoor heat exchanger 102, the blower fan 103, and the filter 108.

  The indoor heat exchanger 102 has a plurality of heat transfer tubes 102a. The indoor heat exchanger 102 is configured to heat or cool the air that has been taken into the indoor unit 100 by the blower fan 103 with the refrigerant that flows through the heat transfer tube 102a. The heat transfer tube 102a communicates with the refrigerant pipe 300 (see FIG. 1) and constitutes a part of a known refrigerant cycle (not shown).

  The left and right wind direction plates 104 are rotated by a left and right wind direction plate motor (not shown) with a pivot shaft (not shown) provided at the bottom as a fulcrum according to an instruction from a main microcomputer (not shown) of the indoor unit 100. Moved. The left and right wind direction plates 104 are divided into a plurality of parts in the left and right direction, and can simultaneously blow the winds in a plurality of directions.

  In accordance with an instruction from the main microcomputer of the indoor unit 100, the vertical wind direction plate 105 is rotated by a vertical wind direction plate motor (not shown) with pivot shafts (not shown) provided at both ends as fulcrums.

  As shown in FIG. 3, the vertical wind direction plate 105 is divided into three parts, a right vertical wind direction plate 105a, a central vertical wind direction plate 105b, and a left vertical wind direction plate 105c. By dividing the vertical wind direction plate 105 in the left-right direction, it is possible to improve the blowing performance in a plurality of directions. The vertical wind direction plate 105 may be divided into two or four in the left-right direction, or the vertical wind direction plate 105 may be configured without being divided in the left-right direction. You may make it blow.

  As shown in FIG. 2, the front panel 106 is installed so as to cover the front surface of the indoor unit 100, and is configured to be rotatable by a front panel motor (not shown) with the lower end as an axis. The front panel 106 is not limited to this configuration, and may be configured to be fixed to the lower end.

  As the blower fan 103 rotates, the room air is taken in through the air suction port 107 and the filter 108, and the air heat-exchanged by the indoor heat exchanger 102 is guided to the blowout air passage 109a. The air guided to the blowout air passage 109a is adjusted in air direction by the left and right airflow direction plates 104 and the vertical airflow direction plate 105, and is sent to the outside from the air blowing port 109b. The air sent to the outside from the air outlet 109b air-conditions the room.

  The imaging unit 121 is attached in the vicinity of the air outlet 109b. The imaging unit 121 is installed so as to face downward by a predetermined angle with respect to the horizontal direction from its own attachment position. Thereby, it is possible to appropriately capture the room in which the indoor unit 100 is installed. However, the mounting position of the imaging unit 121 and the installation angle thereof may be set in accordance with the specification and application of the air conditioner A, and the configuration thereof is not limited.

  The configuration of the air conditioner A of this embodiment is merely an example, and the present invention can be applied to any form of air conditioner.

  FIG. 4 is a configuration diagram illustrating an outline including the control unit 130 of the air conditioner A.

  The control unit 130 of the air conditioner A includes an image recognition unit 131, an object temperature detection unit 132, a storage unit 133, and an air conditioning control unit 136. The control unit 130 drives the load 150 based on each sensor information.

  The control unit 130 is connected to the imaging unit 121, the thermopile 122, the room temperature sensor 123, and the like.

  The imaging unit 121 continuously images the air-conditioned room, converts it into image information, and outputs it to the control unit 130.

  The thermopile 122 captures the temperature distribution of each part in the air-conditioned room in a non-contact manner, acquires it as a thermal image, and outputs it to the control unit 130. The room temperature sensor 123 measures the room temperature in the air-conditioned room.

  The control unit 130 receives image information input from the imaging unit 121, a thermal image input from the thermopile 122, a room temperature input from the room temperature sensor 123, a command signal input from the remote controller Re, and input from various sensors. The operation of the air conditioner A is comprehensively controlled according to the sensor output.

  The image recognition unit 131 of the control unit 130 recognizes the indoor environment based on the image information captured by the imaging unit 121, recognizes each part of the person, and notifies the object temperature detection unit 132. Note that the image recognition unit 131 may recognize the indoor environment based on the information of the thermal image input from the thermopile 122, recognize each part of a person, and notify the object temperature detection unit 132 of the recognition. Thereby, the imaging unit 121 can be omitted.

  The object temperature detection unit 132 detects the human face and limbs (parts other than the face) from the position of each part of the person recognized by the image recognition unit 131 and the thermal image indicating the temperature of each part in the air-conditioned room. And the temperature of the temperature object at the specified at least one part is detected in a non-contact manner. Thereby, the air conditioner A can adjust an air-conditioning driving | operation based on the temperature of each part of a person. Note that when the image recognition unit 131 recognizes each part of a person based on the information of the thermal image input from the thermopile 122 and notifies the object temperature detection unit 132 of the image information and the thermal image captured by the imaging unit 121. There is an effect that it is not necessary to consider the deviation.

  The image recognition unit 131 according to the present exemplary embodiment includes a face recognition unit 1311 and a limb recognition unit 1312.

  The face recognition unit 1311 recognizes a human face from the image information. Here, the face recognition unit 1311 recognizes an exposed part of the skin in the face, not a simple face. Thereby, the influence of temperature detection by a hat or a mask can be eliminated. Instead of the face portion, other parts such as the neck and face that can easily maintain a constant body temperature may be detected. When the word “face” is used, it includes other parts such as the neck and head that are easy to maintain a constant body temperature. In addition, when the term “parts other than the face part” is used, it includes limbs and parts that easily change body temperature.

  The limb recognition unit 1312 detects a person's foot or hand (a part other than the face) from the image information. The limb recognition unit 1312 first tries to recognize the exposed part of the skin of the person's foot, and if the recognition fails, tries to recognize the exposed part of the skin of the hand. This is because the foot that is farthest from the heart is more suitable for estimating the human body temperature. Further, by recognizing the exposed part of the skin, it is possible to eliminate the influence on temperature detection by socks and gloves.

  The image recognizing unit 131 detects whether the image captured by the imaging unit 121 includes a face part of the human body as a detection target and / or a part other than the face part, and also detects an image region of the detection target.

  The storage unit 133 includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. And the program memorize | stored in ROM is read by the control microcomputer, expand | deployed to RAM, and is performed.

  The air conditioning control unit 136 adjusts the set temperature or the wind direction when the temperature of the human face and / or the part other than the face obtained from the thermopile 122 during the air conditioning operation satisfies a predetermined condition. Detailed control contents of the air conditioning control unit 136 will be described later.

  For example, the load 150 is installed in the compressor motor 151 included in the outdoor unit 200, the blower fan motor 152 included in the indoor unit 100, the left / right wind direction motor 153 installed in the left / right wind direction plate 104, and the up / down wind direction plate 105. And a vertical wind direction plate motor 154. These left and right wind direction plates 104 and left and right wind direction plate motors 153, and the upper and lower wind direction plates 105 and the upper and lower wind direction plate motors 154 are wind direction control units that control the air direction of the air conditioning.

  The comfortable operation control during the cooling operation of the air conditioner A in the present invention will be described with reference to FIGS. 1 to 4 as appropriate with reference to FIGS.

  FIG. 5 is a flowchart of the cooling operation process of the comfortable operation control according to the first embodiment.

  The operation in the cooling comfortable operation control mode is started by the operation of setting the comfortable operation control mode from the remote controller Re.

  In step S10, the air conditioning control unit 136 performs the cooling operation for a predetermined period. Here, the air-conditioning control unit 136 is not different from the normal cooling operation mode, and the vertical airflow direction plate 105 (the right vertical airflow direction plate 105a, the central vertical airflow direction plate 105b, the left side) of the outlet of the indoor unit 100 (see FIGS. 2 and 3). The vertical wind direction plate 105c) is made substantially horizontal. However, this is not the case when the up-and-down wind direction plate 105 is set downward with the remote controller Re according to the user's preference. The direction of the right and left wind direction plate 104 is not particularly limited, but it is desirable to allow the wind to spread throughout the room, such as by swinging in the left and right direction.

  In step S11, if the set temperature has not reached the set temperature (No), the air conditioning control unit 136 returns to the process of step S10 and continues the normal cooling operation. This determination is repeated once for several minutes to several tens of minutes. When the room temperature decreases with time and reaches the set temperature (Yes), the air conditioning control unit 136 proceeds to the process of step S12.

  In step S <b> 12, the object temperature detection unit 132 determines the human face, limbs (face part) from the position of each part of the person recognized by the image recognition unit 131 and the thermal image indicating the temperature of each part in the air-conditioned room. And the temperature of the temperature object of the specified at least one part is detected in a non-contact manner.

  In step S13, the air-conditioning control unit 136 determines whether the temperature of the limbs (parts other than the face) with respect to the temperature of the face is lower than or equal to a predetermined temperature (α degree: a first predetermined value) or the temperature of the face. Is reduced to 35 degrees (the fifth predetermined value) or less. The air-conditioning control unit 136 proceeds to the process of step S15 if any determination condition is satisfied (Yes), and performs the cooling operation in step S14 if any determination condition is not satisfied (No). Here, the threshold value of the temperature difference (α degree) of the part other than the face with respect to the temperature of the face is desirably 2 degrees, but any value between 1 degree and 2 degrees may be selected. The process of step S13 determines whether or not this person feels cold.

  Since the resolution of the thermal image input from the thermopile 122 decreases as the area where the person is located is farther from the indoor unit 100, the determination in step S13 is performed when the person is within the predetermined range from the indoor unit 100. It may be.

  In step S14, the air-conditioning control unit 136 performs the cooling operation for a predetermined period, and then returns to the process of step S12. As a result, the temperature monitoring of the human face and the temperature of the part other than the human face are repeatedly executed.

  In step S15, the air conditioning control unit 136 performs control to increase the set temperature and prevent overcooling. The change width of the set temperature is, for example, 1 to 2 degrees.

  In step S16, the air conditioning control unit 136 determines whether or not an air conditioning operation stop operation has been performed. If the air conditioning operation stop operation has not been performed (No), the process returns to the cooling operation processing in step S14. . The air conditioning control unit 136 stops the cooling operation when an operation for stopping the air conditioning operation is performed (Yes).

  With this comfortable operation control, the air conditioner A main body adjusts the set temperature before the person feels cold during cooling, thereby preventing overcooling, so that comfortable air conditioning can always be realized.

  FIG. 6 is a graph of experimental results over time of the skin surface temperature during the cooling operation of Example 1. The vertical axis of the graph indicates the temperature of each part of the body, and the horizontal axis indicates the elapsed time.

  The temperature of the neck or neck (the temperature of the face) is almost constant. However, the temperature of the instep or heel (foot temperature) gradually decreases with time. Here, when 25 minutes passed and the foot temperature was lower by about 1 to 2 degrees than the face temperature, the sensation of coldness was felt. That is, the condition for the person to feel the coldness of the cooling is when the temperature of the foot (part other than the face) with respect to the temperature of the face is lowered to −2 degrees or less. Also, when the temperature of the hand (the part other than the face) is lowered to -2 degrees or less with respect to the temperature of the face instead of the temperature of the foot, it seems that the cold is similarly felt.

  Similarly, it is presumed that the condition that the person feels the thickness of the heating is when the temperature of the hand part or the foot part (the part other than the face part) is higher by +2 degrees or more than the temperature of the face part.

  FIG. 7 is a flowchart of the heating operation process of the comfortable operation control according to the first embodiment.

  The operation in the heating comfortable operation control mode is started by the operation of setting the comfortable operation control mode from the remote controller Re.

  In step S20, the air conditioning control unit 136 performs the heating operation over a predetermined period. Here, the air-conditioning control unit 136 is not different from the normal heating operation mode, and the vertical airflow direction plate 105 (the right vertical airflow direction plate 105a, the central vertical airflow direction plate 105b, the left vertical airflow direction) of the outlet of the indoor unit 100 (see FIG. 2). The plate 105c) is turned downward so that the warm air reaches the floor surface. However, this is not the case when the up / down wind direction plate 105 is set upward from the initial value by the remote controller Re according to the user's preference. The direction of the right and left wind direction plate 104 is not particularly limited, but it is desirable to allow the wind to spread throughout the room, such as by swinging in the left and right direction.

  In step S21, if the air conditioning control unit 136 has not reached the set temperature (No), the process returns to the process of step S20 and continues the normal heating operation. This determination is repeated once for several minutes to several tens of minutes. When the room temperature increases with time and reaches the set temperature (Yes), the air conditioning control unit 136 proceeds to the process of step S22.

  In step S <b> 22, the object temperature detection unit 132 determines the human face, limbs (face part) from the position of each part of the person recognized by the image recognition unit 131 and the thermal image indicating the temperature of each part in the air-conditioned room. And the temperature of the temperature object of the specified at least one part is detected in a non-contact manner.

  In step S23, the air-conditioning control unit 136 determines whether the temperature of the limbs (parts other than the face) with respect to the temperature of the face is higher than a predetermined temperature (β degree: second predetermined value) or the temperature of the face. Is determined to rise to 36 degrees (sixth predetermined value) or more. The air-conditioning control unit 136 proceeds to the process of step S25 if any determination condition is satisfied (Yes), and performs the heating operation of step S24 if any determination condition is not satisfied (No). Here, the threshold of the temperature difference (β degrees) of the limbs (parts other than the face) with respect to the temperature of the face is preferably 2 degrees, but any value between 1 degree and 2 degrees is selected. May be. The process of step S23 determines whether or not this person feels hot.

  In step S24, the air conditioning control unit 136 performs the heating operation for a predetermined period, and then returns to the process of step S22. Thereby, the temperature monitoring of the human face and the temperature of the human limbs (parts other than the face) are repeatedly executed.

  In step S <b> 25, the air conditioning control unit 136 performs control to lower the set temperature and prevent overheating. The change width of the set temperature is, for example, 1 to 2 degrees.

  In step S26, the air conditioning control unit 136 determines whether or not an air conditioning operation stop operation has been performed. If the air conditioning operation stop operation has not been performed (No), the process returns to the heating operation processing in step S24. . The air conditioning control unit 136 stops the heating operation when an operation for stopping the air conditioning operation is performed (Yes).

  By this comfortable operation control, the air conditioner A main body adjusts the set temperature to prevent overheating before it feels hot during heating, so that comfortable air conditioning can always be realized.

  Next, a second embodiment of the air conditioner according to the present invention will be described with reference to FIGS. 1 to 4 as appropriate using FIGS. In the first embodiment, the number of occupants is not limited, but in the second embodiment, comfortable driving control when there are one or more occupants will be described.

  When there are a plurality of people in the room, there are individual differences in bodily sensations. Therefore, if the set temperature is raised during cooling operation or lowered during heating operation as in the control shown in Example 1, it is comfortable for one person. Even so, it may be uncomfortable for the other person. Therefore, when there are a plurality of people in the room as in the second embodiment, not only the set temperature but also the wind direction is adjusted, and air conditioning control is performed to make each person comfortable.

  FIG. 8 is a flowchart of the cooling operation process of the comfortable operation control according to the second embodiment.

  In the second embodiment, as in the first embodiment, the operation in the cooling comfortable operation control mode is started by the operation of setting the comfortable operation control mode from the remote controller Re.

  The processes in steps S10 and S11 are the same as the processes in steps S10 and S11 in FIG. Thus, at the beginning of operation, there is no change from the normal cooling operation mode. When the room temperature decreases with time and reaches the set temperature, the process proceeds to step S12.

  The process of step S12 is the same as the process of step S12 of FIG. In this process, the object temperature detection unit 132 detects the position of each part of the individual recognized by the image recognition unit 131 and the thermal image indicating the temperature of each part in the air-conditioned room. A part other than the face) is identified, and the temperature of the temperature object of the identified at least one part is detected without contact.

  In step S13, the air-conditioning control unit 136 determines whether the temperature of the limbs (parts other than the face) with respect to the temperature of the face is lower than or equal to a predetermined temperature (α degree: a first predetermined value) or the temperature of the face. Is reduced to 35 degrees (the fifth predetermined value) or less. The air-conditioning control unit 136 proceeds to the windshield control process in step S131 if any of the determination conditions is satisfied (Yes), and performs the cooling operation in step S14 if any of the determination conditions is not satisfied (No). carry out. In the process of step S13, it is determined whether or not a certain occupant feels cold.

  In the process of step S131, the air conditioning control unit 136 performs so-called wind protection control that adjusts the left and right wind direction plates 104 and the upper and lower wind direction plates 105 so that the cool air does not reach the person who is determined to be cold. Avoid getting cold from the experience.

  FIG. 9 is an explanatory diagram illustrating windbreak control during the cooling operation of the second embodiment. FIG. 9A is a side view of the room, and FIG. 9B is a top view of the room. In step 131, the air-conditioning control unit 136 determines the direction of the vertical airflow direction plates 105 (the right vertical airflow direction plate 105a, the central vertical airflow direction plate 105b, and the left vertical airflow direction plate 105c) of the outlet of the indoor unit 100 (see FIGS. 2 and 3). A person who is judged to be feeling cold by making the horizontal direction as shown in FIG. 9A and the direction of the left and right wind direction plate 104 in the range excluding the person as shown in FIG. 9B. Make sure that cold air doesn't spread around. Note that the left and right wind direction plates 104 may be swung within a range excluding the person.

  In the process of step S132, the air-conditioning control unit 136 determines whether or not another person is present in the room, and if it is present (Yes), the process returns to the process in step S12, and the temperature of each part of the other person is determined. Measure. By the processing from step S12 to step S132, the windbreak control for all the persons who satisfy the determination condition of step S13 is performed.

FIG. 10 is an explanatory diagram illustrating windbreak control during the cooling operation of the second embodiment. FIG. 10A is a side view of the room, and FIG. 10B is a top view of the room. In step 132, the air-conditioning control unit 136 determines the direction of the vertical airflow direction plates 105 (the right vertical airflow direction plate 105a, the central vertical airflow direction plate 105b, the left vertical airflow direction plate 105c) of the outlet of the indoor unit 100 (see FIGS. 2 and 3).

If the air conditioning operation stop operation has not been performed (No), the process returns to the heating operation processing in step S24. . The air conditioning control unit 136 stops the heating operation when an operation for stopping the air conditioning operation is performed (Yes).

  Here, the threshold value of the temperature difference (β degree: second predetermined value) of the part other than the face part of the body with respect to the temperature of the face part is set to −2 to −1 degree as in the first embodiment.

  By these comfortable operation controls, even when there are multiple people in the room, before the air conditioner A body feels cold before cooling, the air conditioner A automatically adjusts the set temperature to prevent overcooling, and before heating it feels hot In order to prevent overheating, comfortable air conditioning can always be realized.

If the air conditioning operation stop operation has not been performed (No), the process returns to the cooling operation processing in step S14. . The air conditioning control unit 136 stops the cooling operation when an operation for stopping the air conditioning operation is performed (Yes).

  This comfortable operation control prevents overcooling after the windbreak control for the occupants. Since the air conditioner A main body is protected from the wind and the set temperature is adjusted to prevent overcooling, it is possible to always realize comfortable air conditioning.

  Next, comfortable operation control at the time of heating operation in the case where there is one occupant will be described.

  FIG. 15 is a flowchart of the heating operation process of the comfortable operation control according to the third embodiment.

  In the third embodiment, as in the first embodiment, the operation in the heating comfortable operation control mode is started by the operation of setting the comfortable operation control mode from the remote controller Re.

  The processes in steps S20 and S21 are the same as the processes in steps S20 and S21 in FIG. Thus, at the beginning of the operation, there is no change from the normal heating operation mode. When the room temperature decreases with time and reaches the set temperature, the process proceeds to step S22.

  The process of step S22 is the same as the process of step S22 of FIG. In this process, the object temperature detection unit 132 detects the position of each part of the individual recognized by the image recognition unit 131 and the thermal image indicating the temperature of each part in the air-conditioned room. A part other than the face) is identified, and the temperature of the temperature object of the identified at least one part is detected without contact.

The air-conditioning control unit 136 proceeds to the process of step S31 if any determination condition is satisfied (Yes), and performs the heating operation of step S24 if any determination condition is not satisfied (No). Here, the threshold value of the temperature difference (β degree) of the part other than the face part of the body with respect to the temperature of the face part is desirably 2 degrees, but any value between 1 degree and 2 degrees may be selected. . The process of step S23 determines whether or not this person feels hot.

  In the process of step S231, the air-conditioning control unit 136 performs so-called wind protection control that adjusts the left and right wind direction plates 104 and the upper and lower wind direction plates 105 so that warm air does not reach the individual so as not to get hot from the experience. . The process in step S231 is the same as the process in step S231 in FIG. 11 (see FIG. 12). The air conditioning control unit 136 performs the heating operation for a predetermined period after the windbreak control.

  In step S234, the air conditioning control unit 136 determines that the temperature of the part other than the face with respect to the temperature of the face is higher than a predetermined temperature (β degree: second predetermined value) or the temperature of the face is 36 degrees ( It is determined again whether it has risen to the sixth predetermined value) or more.

The air conditioning control unit 136 stops the heating operation when an operation for stopping the air conditioning operation is performed (Yes).

  As described above, the comfortable driving control according to the third embodiment prevents excessive cooling after the windbreak control for the occupant. The air conditioner A main body protects against wind and adjusts the set temperature to prevent overcooling, so that comfortable air conditioning can always be realized. According to the third embodiment, the air conditioner A itself can determine the feeling of hot and cold for each individual, can always realize comfortable air conditioning, and can also combine wind direction control even when multiple people are in the same space. The air conditioner A that realizes comfortable air conditioning suitable for an individual can be provided.

  Next, a fourth embodiment of the air conditioner according to the present invention will be described with reference to FIGS. 1 to 4 as appropriate with reference to FIGS. In the first embodiment, the air conditioner A determines a feeling of hotness and coldness for each individual and realizes comfortable air conditioning. On the other hand, in the fourth embodiment, the constitution is easy to feel hot and the constitution that is easy to feel cold. Air conditioner A judges the constitution and realizes comfortable air conditioning suitable for individuals.

  FIG. 16 is a flowchart of cooling operation processing for comfortable operation control according to the fourth embodiment.

  In the fourth embodiment, as in the first embodiment, the operation in the cooling comfortable operation control mode is started by the operation of setting the comfortable operation control mode from the remote controller Re.

  The processes in steps S10 and S11 are the same as the processes in steps S10 and S11 in FIG. Thus, at the beginning of operation, there is no change from the normal cooling operation mode. When the room temperature decreases with time and reaches the set temperature, the process proceeds to step S141.

  In step S141, it is detected whether or not there is a person in the room using the image captured by the image capturing unit 121 or the thermal image captured by the thermopile 122 (person detecting unit). If there is a person in the room, the process proceeds to step S142. If there is no person in the room, the cooling operation in step S10 is performed.

  In step S142, time measurement is started. By determining the state after a predetermined time has elapsed and the individual's body temperature has changed due to cooling, the individual's constitution is more accurately determined.

  The process of step S143 is the same as the process of step S12 of FIG.

  In step S144, the air conditioning controller 136 determines that the temperature of the part other than the face relative to the temperature of the face is lower than a predetermined temperature (α degree: a first predetermined value) or the temperature of the part other than the face is lower. It is determined whether the temperature has decreased to a predetermined temperature (γ degree: third predetermined value) or less. The air-conditioning control unit 136 proceeds to the processing of step S145 if any determination condition is satisfied (Yes), and performs any cooling operation without performing these controls if any determination condition is not satisfied (No). To do.

  Here, the threshold value α will be described. FIG. 18 is an explanatory diagram showing the relationship between room temperature and body temperature. FIG. 19 is an explanatory diagram showing the relationship between the temperature difference of a human part and the constitution. From FIG. 18, it can be seen that the temperature of the elbow (face) does not change much even when the room temperature changes, whereas the temperature of the feet and hands (parts other than the face) decreases as the room temperature decreases. Therefore, the lower the room temperature, the greater the difference between the temperature of the knee (face) and the temperature of the feet and hands (parts other than the face). Therefore, it is desirable to change the threshold value α according to the room temperature. Specifically, as shown in FIG. 19, the human constitution can be more accurately determined by increasing the value of the threshold α as the room temperature is lower. In the example of FIG. 19, if the temperature of the brain (face) with respect to the feet and hands (parts other than the face) is higher than the threshold value α, the person's constitution is determined to be a constitution that is likely to feel cold.

  Next, the threshold value γ will be described. FIG. 20 is an explanatory diagram showing the relationship between the temperature and constitution of parts other than the human face. As shown in FIG. 18, the temperature of the person's feet and hands (parts other than the face) tends to decrease in proportion to the decrease in the room temperature, whereas the temperature of the person's knee (face) changes so much. do not do. Therefore, the human constitution may be determined based on the temperature of the person's feet and hands (parts other than the face) without using the temperature of the person's shin (face). Specifically, the lower the room temperature, the lower the value of the threshold γ. If the temperature of a person's foot or hand (part other than the face) is lower than the threshold γ, the person's constitution is likely to feel cold. Judge.

  In the process of step S145, the air-conditioning control unit 136 determines that the individual is likely to feel cold, and adjusts the left and right wind direction plates 104 and the upper and lower wind direction plates 105 so as to prevent cold air from spreading to the individual. Use windbreak control to avoid getting cold. The process in step S145 is the same as the process in step S131 in FIG. 8 (see FIG. 9). The air conditioning control unit 136 may perform control to prevent overcooling by increasing the set temperature instead of the windscreen control or together with the windscreen control. The change width of the set temperature is, for example, 1 to 2 degrees.

  Furthermore, instead of increasing the set temperature of the entire room, the set temperature of the area where the individual is present may be increased. FIG. 21 is an explanatory diagram showing a screen portion during the cooling operation of the remote controller of the air conditioner. FIG. 22 is an explanatory diagram illustrating area control during the cooling operation of the fourth embodiment. FIG. 22A is a side view of the room, and FIG. 22B is a top view of the room.

  For example, when a person whose constitution is easy to feel cold is in the right back area as viewed from the indoor unit 100, as shown in FIG. 21, so-called area air conditioning is performed so that the temperature in the right back area becomes high. Do not impair the comfort of people in areas other than the back right.

  When performing area air conditioning, the direction of the right side vertical wind direction plate 105a and the central vertical direction plate 105b is made substantially horizontal, the direction of the left side vertical wind direction plate 105c is made downward, and the wind is made up and down as shown in FIG. Try to blow. Then, as shown in FIG. 22B, the direction of the left and right wind direction plates 104 is set so as to face the range excluding the right back area, so that the cool air does not reach the right back area. Note that the left and right wind direction plates 104 may be swung within a range excluding the area on the right back. Further, the direction of the central vertical wind direction plate 105b may be downward. Although not shown, when the up / down wind direction plate 105 is divided into two parts, the direction of the right side up / down wind direction plate is made substantially horizontal and the direction of the left side up / down wind direction plate is made downward.

  Next, comfortable operation control during heating operation will be described. FIG. 17 is a flowchart of the heating operation process of the comfortable operation control according to the fourth embodiment.

  The processes in steps S20 and S21 are the same as the processes in steps S20 and S21 in FIG.

  The processes in steps S241, S242, and S243 are the same as the processes in steps S141, S142, and S143 in FIG.

  In step S244, the air conditioning control unit 136 determines that the temperature of the part other than the face with respect to the temperature of the face is higher than a predetermined temperature (β degree: second predetermined value) or the temperature of the part other than the face. It is determined whether the temperature has risen to a predetermined temperature (Ω degree: fourth predetermined value) or more. The air-conditioning control unit 136 proceeds to the process of step S245 if any determination condition is satisfied (Yes), and performs any heating operation without performing this control if any determination condition is not satisfied (No). . In the process of step S244, it is determined whether or not this person's constitution is likely to be felt hot or otherwise.

  Here, the threshold value β will be described. As shown in FIG. 19, the value of the threshold β is increased as the room temperature is higher. If the temperature of the person's pleat (face) relative to the feet and hands (parts other than the face) is smaller than the threshold value β, the person's constitution is determined to be a constitution that is easily felt as hot.

  Next, the threshold value Ω will be described. FIG. 20 is an explanatory diagram showing the relationship between the temperature and constitution of parts other than the human face. As shown in FIG. 18, the temperature of a person's foot and hand (parts other than the face) tends to increase in proportion to the increase in room temperature. Therefore, the higher the room temperature, the higher the value of the threshold Ω, and if the temperature of the person's feet and hands (parts other than the face) is higher than the threshold Ω, the person's constitution is judged to be a constitution that is easily felt as hot. .

  In the process of step S245, the air conditioning control unit 136 determines that the individual is likely to feel hot and adjusts the left and right wind direction plates 104 and the upper and lower wind direction plates 105 so that warm air does not reach the individual. Use windbreak control to avoid getting hot. The process in step S245 is the same as the process in step S231 in FIG. 11 (see FIG. 12). The air-conditioning control unit 136 may perform control to lower the set temperature instead of the windscreen control or together with the windscreen control. The change width of the set temperature is, for example, 1 to 2 degrees.

  Further, instead of lowering the set temperature of the entire room, the set temperature of the area where the individual is present may be lowered. FIG. 23 is an explanatory diagram showing a screen portion during heating operation of the remote controller of the air conditioner. FIG. 24 is an explanatory diagram illustrating area control during the heating operation of the fourth embodiment. FIG. 24A is a side view of the room, and FIG. 24B is a top view of the room.

  For example, when a person whose constitution is easy to feel cold is in the right back area when viewed from the indoor unit 100, as shown in FIG. 23, so-called area air conditioning is performed so that the temperature of the right back area is lowered. Do not impair the comfort of people in areas other than the back right.

  When area air conditioning is performed, as shown in FIG. 24A, the direction of the vertical wind direction plate 105 (the right vertical wind direction plate 105a, the central vertical wind direction plate 105b, the left vertical wind direction plate 105c) is set downward. Then, as shown in FIG. 24B, the direction of the right and left wind direction plate 104 is set to be in a range excluding the right area, so that warm air does not reach the right area. The left and right wind direction plates 104 may be swung within a range excluding the right area.

  As described above, according to the present embodiment, the air conditioner A determines the constitution of each person, which is a constitution that is easy to feel when it is hot and a constitution that is easy to feel when it is cold, and it is possible to realize comfortable air conditioning suitable for the individual. In this embodiment, it is determined whether or not the human constitution is easy to feel cold during the cooling operation, and whether or not the human constitution is easy to feel hot during the heating operation is determined. However, it may be judged whether the human constitution is likely to feel hot during cooling operation, or whether the human constitution is likely to feel cold during heating operation. May be.
