The blowout port 29 can be opened and closed by the rotation of the upper wind direction plate 291 and the lower wind direction plate 292 attached to the casings 290a and 290b. These upper wind direction plate 291 and lower side wind direction plate 292 blow the air flow indoors by controlling the air flow from the indoor unit 2 up and down.

  Filters 231 and 231 ′ are installed inside the decorative panel 25 and the suction port 27 on the upper surface of the indoor unit 2, and are detachably attached to the unit frame 22. Inside the filters 231 and 231 ′, a heat exchanger 33 composed of heat transfer tubes 331 and fins is disposed. The heat exchanger 33 is disposed so as to surround the blower fan 311 having substantially the same horizontal length. The blower fan 311 is disposed between the front casing 290a and the rear casing 290b, and the rotation shaft of the blower fan 311 is connected to the blower motor.

  A blowout air passage 290 is formed between the blower fan 311 and the blowout opening 29 by a front casing 290a and a rear casing 290b, and left and right airflow direction plates 295 are arranged in the blowout air passage 290 at predetermined intervals in the left-right direction.

  As described above, the outer casing of the indoor unit 2 is formed by a casing including the casing base 21, the unit frame 22, the decorative frame 23, the lower panel 24, and the like. The decorative panel 25, the blower fan 311, and the filter 231 are formed in the casing. , 231 ′, heat exchanger 33, dew tray 35, left and right wind direction plate 295, suction panel 251, upper wind direction plate 291, lower wind direction plate 292, etc. are attached to constitute indoor unit 2.

  In the back of the decorative panel 25, an electrical component part of the electrical component unit is provided. The control board of the electrical component unit is provided with a microcomputer, receives a signal sent from the remote controller 5 through the light receiving unit 396, and controls the operation of the air conditioner according to the signal. At this time, the operation mode can be confirmed by turning on and off the lamp of the display unit according to the operation mode.

  When the operation is started, the suction panel 251 of the decorative panel 25 rotates forward with the lower portion as a fulcrum and tilts by a predetermined angle, and the front upper portion and the side portion of the indoor unit 2 are opened. The upper wind direction plate 291 and the lower wind direction plate 292 rotate under the control of the microcomputer to open and close the outlet 29 of the indoor unit 2. When the indoor unit 2 receives the operation signal from the remote controller 5, the outdoor unit 6 also operates. The refrigerant sent from the outdoor unit 6 circulates through the heat exchanger 33 via the connection pipe 8. The blower motor connected to the blower fan 311 is driven in accordance with the operating state by microcomputer control.

  Next, the flow from the air suction to the blowout will be described. When the blower fan 311 rotates clockwise in FIG. 2, room air is sucked from the upper suction port 27 on the upper surface and the opening (front suction port 27 ′) of the decorative panel 25.

The condensed water collected in the dew tray 33 is discharged outside through the drain pipe 37. In this way, the air flow path is formed and the blower fan 311 is driven, so that the indoor air is sucked from the suction ports 27 and 27 ′, passes through the filters 231 and 231 ′, and is heated in the heat exchanger 33. After the replacement, the air is blown into the room from the air outlet 29.

  Next, the imaging range of the imaging device mounted on the air conditioner of the embodiment will be described with reference to FIGS. FIG. 3 is an image area division diagram of the image sensor mounted on the indoor unit. FIG. 4 is a detection diagram of the solar radiation region captured by the image sensor. FIG. 5 is a detection diagram when the solar radiation area captured by the image sensor and the human presence area are different. FIG. 6 is a detection diagram when the solar radiation area captured by the image sensor and the human presence area overlap.

  3 to 6, 901 is a room, 64 is a left region, 65 is a central region, 66 is a right region, 68 is a solar radiation region, and 920 is a human body.

  The air conditioner 1 according to the embodiment has a function of capturing an image of a room with the image sensor 110, detecting a color temperature of light incident on the image sensor from image data, and a function of detecting brightness. It has a human detection function that detects the presence or absence of a human body. The color temperature detection function, brightness detection function, and human detection function are widely used for camera white balance control, automatic iris control, and energy-saving operation control of air conditioners. Avoid detailed description in.

  Since the imaging element 110 has a limited image capture range, in this embodiment, the imaging element rotation mechanism 111 is provided to change the imaging direction of the imaging element 110 so that the imaging direction of the imaging element 110 can be changed. I did it. Reference numeral 64 in FIG. 3 denotes an imaging area when the imaging direction is directed to the left. In this imaging direction, imaging data of the left area in the room is acquired. Reference numeral 65 denotes an imaging region when the imaging direction is directed toward the center, and reference numeral 66 denotes an imaging region when the imaging direction is directed toward the right. The imaging data of the center and right regions in the room are respectively acquired.

  Next, a method for detecting the presence of solar radiation in the room will be described with reference to FIGS. FIG. 7 is a sectional view for identifying the type of light source from the data of the image sensor.

  4 and 7, 71 is a region where the color temperature index of the light source is larger than the color temperature index of the sun, 72 is a region where the light source is identified as the sun, 73 is a region where the light source is identified as a fluorescent lamp, 74 Is a region where the light source is identified as an incandescent bulb, 75 is a region where the color temperature index of the light source is lower than the color temperature index of the incandescent lamp, 81 is an upper limit of the color temperature index which identifies the light source as sunlight, and 82 is a fluorescent light source The upper limit of the color temperature index for identifying the light source, 83 is the upper limit of the color temperature index for identifying the light source as an incandescent lamp, and 84 is the lower limit of the color temperature index for identifying the light source as an incandescent lamp.

  FIG. 4 shows an example in which sunlight is present in many parts of the left region 64 and a part of the central region 65. In this case, the air conditioner 1 applies the image pickup direction from the image data of the left region 64 to the image sensor 110. The color temperature of incident light is detected, and when the color temperature is close to the color temperature of sunlight, the type of light source is identified as sunlight.

  Specifically, a color temperature index having a positive correlation with the color temperature of the light incident on the image sensor 110 shown in FIG. 7 is provided, and the color temperature index is an upper limit 82 of the color temperature index that identifies the light source as a fluorescent lamp. When the light source is between the upper limit 81 of the color temperature index that identifies sunlight, the type of light source is identified as sunlight.

  Next, a method for determining the magnitude of radiation when there is solar radiation will be described with reference to FIG. FIG. 8 is a division diagram for determining the magnitude of radiation from the data of the image sensor.

  In FIG. 8, 77 is a range of a brightness index that is determined to be large radiation, 78 is a range of a brightness index that is determined to be low radiation, 79 is a range of a brightness index that is determined to be no radiation, and 87 is a large radiation level. The lower limit value of the brightness index determined as, and 88 is the lower limit value of the brightness index determined as low radiation.

  It is a common experience to experience the sun shining from the sun and brightening the room and darkening the sun when it is hidden behind the clouds. At this time, if the range receiving sunlight is wide, it feels brighter, and if the range receiving sunlight is narrow, it feels darker. At this time, naturally, if the sunlight is bright, the radiation from the portion receiving the sunlight increases, and if the sunlight is dark, the radiation decreases.

  Therefore, the inventors consider that there is a correlation between the indoor brightness detected by the image sensor 110 and the magnitude of radiation when the light source is the sun, and the brightness from the image data of the image sensor 110 is bright. At the same time, the magnitude of the radiation at that time was found from the image data of the human detection function, and the relationship between the brightness index and the magnitude of the radiation as shown in FIG. 8 was found.

  As shown in FIG. 8, the magnitude of radiation is divided into three levels of radiation magnitude, small radiation, and no radiation, and when the brightness index exceeds the lower limit value 87 of the brightness index that is determined to be large radiation, radiation from sunlight is When the brightness index is between the lower limit value 88 of the brightness index for which the brightness index is determined to be low radiation and the lower limit value 87 of the brightness index for which the brightness index is determined to be high, the radiation due to sunlight is small and the brightness index Is less than the lower limit 88 of the brightness index determined to be low radiation, it is assumed that there is no radiation from sunlight.

  Needless to say, the brightness index has a positive correlation with the illuminance, luminance, luminous flux, luminous intensity, or light quantity derived from the imaging data.

  As described above, the air conditioner according to the embodiment has a function of mounting an imaging device, detecting the color temperature of light incident on the imaging device, identifying the type of light source, and determining the brightness level. Have.

  Generally, color temperature is used as a means for expressing a color by a physical numerical value. This represents the color emitted when a black body is heated by the temperature of the black body at that time, 1,800K for the candle flame, 2,800K for the incandescent bulb, 5,200K for the daylight fluorescent lamp, It is said to be 5,500K for sunlight in the middle, 7,500K for shade in sunny weather, and 12,000K for clear sky.

  In recent years, digital cameras use an image sensor to determine the approximate color temperature of the light source, automatically adjust the white balance, and adjust the color tone of the image so that even an amateur can shoot it in the correct color tone It is becoming. In this case, the calculated color temperature often deviates from the correct color temperature, but it is sufficient that the color is an appropriate color when printing an image. Therefore, the approximate color obtained is more accurate than the accuracy of the color temperature itself. The correlation between temperature and color development at the time of printing is important, and the accuracy of color temperature is not important.

  Many digital cameras have a built-in AE function. In this case, exposure is determined based on brightness information captured by the image sensor.

  In the air conditioner of the embodiment, as described above, an approximate color temperature is detected using an image sensor that is frequently used in a digital camera. In addition, by using the AE function, the degree of brightness is divided into a plurality of stages, and it is determined to which stage the observed brightness belongs.

  The color temperature of direct sunlight is about 5,500K, which does not change much in winter or summer. Moreover, in a day, it will be 1,900-2500K in the morning sun or sunset, and will be 6,500K in the daytime when it is cloudy. In addition, the white LED bulb that has recently seen signs of widespread use is 5,200K.

  When heating or cooling a room, whether direct sunlight is inserted through the window or not is greatly affected by the heating or cooling load. As mentioned above, the color temperature of direct sunlight is about 5,500K. It is lower than this value in the morning and evening when it does not have a significant effect on the heating or cooling load, and higher than this value when it is shaded or cloudy without direct sunlight. Become.

  In addition, the color temperature of incandescent bulbs, fluorescent lamps, and LED bulbs, which are artificial lights, is lower than this value. Thus, by measuring the color temperature in the room, it is possible to know whether direct sunlight is inserted into the room in the measuring direction or not. Furthermore, since it is possible to know the degree of direct sunlight by measuring the brightness, it is possible to control the air conditioner in consideration of the influence of sunlight on the heating or cooling load.

  In this case, if it is possible to distinguish between direct sunlight and shade, cloudy sky, and artificial light, it is not necessary to accurately determine the color temperature, and it is sufficient to experimentally determine a clear relationship between them. .

  For this reason, the air conditioner which can be controlled in consideration of the influence of sunlight can be provided.

  Next, the control method when there is sunlight in the room and there are people in the shade will be described with reference to FIGS. FIG. 5 is a detection diagram when the solar radiation area captured by the image sensor and the human presence area are different.

  In the embodiment, when a person is in the shade, when the radiation from sunlight is large, the set temperature is slightly lowered, energy is saved in the case of heating, and control is performed to maintain the sensory temperature in the case of cooling. . When the radiation from sunlight is small, the set temperature is lowered slightly, energy saving is achieved in the case of heating, and control is performed to maintain the sensible temperature in the case of cooling. When there is no radiation from sunlight, the set temperature is not changed.

  Next, a control method when there is sunlight in the room and there are people in the sunlight will be described with reference to FIGS. FIG. 6 is a detection diagram when the solar radiation area captured by the image sensor and the human presence area overlap.

  In the embodiment, when the indoor position where sunlight is inserted and the position where the person is detected are the same, if the person is in the sunshine and the radiation from sunlight is large, the set temperature is In the case of heating, energy saving is achieved, and in the case of cooling, control is performed to maintain the sensible temperature. When the radiation from sunlight is small, the set temperature is lowered slightly, energy saving is achieved in the case of heating, and control is performed to maintain the sensible temperature in the case of cooling. When there is no radiation from sunlight, the set temperature is not changed.

  As described above, the air conditioner according to the embodiment controls the air conditioner according to the identified type of the light source and the determined brightness level.

  As a result, when the type of light source is sunlight and the brightness level is brighter than a predetermined level, it is estimated that the sunlight in the room is strong, and the temperature is set to the set temperature, assuming that the sensory temperature has increased due to the sunlight. Further, it is possible to perform control to save energy during heating and maintain comfort during cooling. At this time, the amount of room temperature reduction can be adjusted according to the brightness to achieve more detailed energy savings or minimize the energy required to maintain comfort.

  For this reason, the air conditioner which can implement | achieve the energy saving at the time of heating, and the comfort maintenance at the time of cooling with little energy can be provided.

  The air conditioner according to the embodiment controls the air conditioner according to the brightness level when the type of the light source is identified as sunlight.

  As a result, when the brightness stage is brighter than the predetermined level, it is estimated that the sunlight into the room is strong, and the temperature of the temperature is raised by the sunlight. Enhancing the circulation of indoor air, lowering the sensible temperature, and conserving energy by diffusing the air in a place with strong sunlight, which has been gathered during heating, into the room, and also reducing the blowing wind speed to warm the sun. Can be wrapped gently and quietly, and while maintaining comfort, energy can be saved.

  Therefore, it is possible to provide an air conditioner that can be controlled with both comfort and energy saving during heating and cooling.

  In addition, the air conditioner of the embodiment is equipped with a mechanism that can change the imaging direction of the imaging element into a plurality of directions, and performs identification of the type of the light source and determination of the brightness level in each imaging direction. Thus, when the type of the light source is identified as sunlight, the insertion position of sunlight into the room is specified.

  Thereby, it is possible to send the blown air toward a place where the sunlight is strong, or to blow the air away from the place, and it is possible to perform an operation with more detailed comfort and energy saving.

  For this reason, the air conditioner which can perform the operation | movement which aimed at comfort and energy saving more finely can be provided.

  Further, the air conditioner of the embodiment has a human detection function of detecting the presence or absence of a person from a captured image of the image sensor, and is specified when the type of the light source is identified as sunlight. The air conditioner is controlled according to whether a person is present or absent at the sunlight insertion position.

  Thus, for example, when there is a person at the sunlight insertion position during heating operation, the blower of the indoor unit is designed so that the wind speed of the air blown from the indoor unit is reduced or the wind direction is changed so as not to apply the wind And keep the sun-drifting position of the sunlight plug-in position gently and gently. In addition, since people who are in the sun are warming up in warm warmth, the room temperature may be lowered slightly from the set temperature to measure energy saving.

  If there is no person at the sunlight insertion position, control the indoor unit blower so that the wind reaches the sunlight insertion position by increasing the wind speed of the air blown from the indoor unit or changing the wind direction. And push the warmth of the sundrift into the room. In this case, the window into which sunlight is inserted absorbs solar heat and is warmed.Those who are away from the indoor window receive radiation from the window, and the temperature of the experience increases slightly. It is possible to save energy by adjusting the room temperature lower than the setting.

  During cooling operation, if there is a person at the sunlight insertion position, increase the wind speed of the air blown from the indoor unit or change the wind direction so that the wind reaches the person at the sunlight insertion position. The indoor unit blower is controlled to lower the temperature of the person in the sun. In addition, people who are in the sunlight receive glimmering sunlight, and the temperature of the sensible temperature is rising, so the degree of sunlight is judged at the brightness level captured by the image sensor, and this brightness Depending on the stage, the room temperature may be lowered from the set temperature to measure energy saving while maintaining comfort.

  If there is no person at the sunlight insertion position, control the blower of the indoor unit so that the wind speed of the air blown out from the indoor unit is reduced or the direction of the air is not applied, and the sunlight position is adjusted. Prevent hot air from spreading indoors. In this case, the window into which sunlight is inserted absorbs solar heat and is warmed.Those who are away from the indoor window receive radiation from the window, and the temperature of the experience increases slightly. The comfort may be maintained by adjusting the room temperature lower than the setting.

  For this reason, when there is a person at the insertion position of sunlight, an air conditioner that can perform an energy saving operation as much as possible while maintaining comfort can be provided depending on the absence of the person.

  Next, noise prevention at bedtime will be described.

  In addition to the function of heating and cooling, various automatic functions are added to the air conditioner in order to avoid troublesome operations. For example, indoor dust is collected in the filters 231 and 231 'as the air conditioner is operated, and therefore must be periodically cleaned. Air conditioners with an automatic cleaning function that incorporates a function of automating this and automatically cleaning the filters 231 and 231 'are also offered to the market by various companies.

  Many of these functions end in a short time compared to normal air-conditioning operation, and many of the functions are relatively loud due to short-time operation. If such a function starts while a person is sleeping, sleep at a corner is disturbed, causing the user to feel uncomfortable. In order to avoid this, in the present embodiment, when a person is sleeping indoors from the image data of the image sensor 110, when the indoor brightness is darker than a predetermined brightness, such a function is started. Is suspended or postponed to prevent disturbing sleep in the room.

  Functions that are subject to such control include functions that emit noise that is greater than the noise level of an air conditioner that is operated at bedtime, such as the automatic cleaning function described above, and sound that has a low noise level but a specific frequency. There is a function that emits an irritating sound that stands out.

  The air conditioner has various indicator lamps, but the power consumption of the indicator lamp itself is relatively small, but the power consumption cannot be ignored because the lighting time is long. For this reason, according to the brightness of the room, when the room is bright, the display is brightened so that the display can be identified. When the room is dark, the brightness of the display lamp is also darkened. Thereby, the power consumption required for display can be reduced.

  As described above, the air conditioner according to the embodiment stops or postpones the operation of the built-in mechanism in which the driving sound is large according to the brightness level.

  Thereby, when the determined brightness level of the room is dark at night, it is determined to be sleeping, for example, the operation of the automatic cleaning mechanism of the filter, the determined brightness level of the room is Postpones until daytime brightness changes. By carrying out like this, it can prevent that the drive sound which disturbs sleep is emitted from an air conditioner during a person's sleep.

  For this reason, the air conditioner which does not disturb night sleep can be provided.

  Further, the air conditioner of the embodiment adjusts the brightness of the display device according to the brightness level.

  As a result, when there is no illumination at night, the brightness of the display device is set to a level at which the content of the display can be read, and the brightness of the display device is set to a level that can be read as the room brightness increases. Brighten. By doing in this way, the energy saving of a display apparatus can be aimed at.

  For this reason, the air conditioner which can aim at the energy saving of a display apparatus can be provided.

  Next, the air conditioner (air conditioning system) of Embodiment 2 will be described.

  The air conditioner of the second embodiment operates the human detection function even when the operation is stopped, and there are people in the room, and the temperature and humidity in the room reach a level at which there is a risk of getting heat stroke. When the air conditioner is not operated, a message recommending air-conditioning operation is issued. Messages can be sent to people in the room by voice, buzzer, display, etc., and can also be sent to other people living in other rooms. Furthermore, via the telephone or the Internet, a message is sent to the visiting care provider, helper, or the associated hospital. You can do it.

  By doing so, it is possible to reduce the risk of suffering from heat stroke in people who live in urban areas, where the wind does not enter even if the windows are opened, or in the houses where the windows cannot be opened for crime prevention. Moreover, when the position where a person exists and the position where sunlight is inserted coincide with each other, the temperature / humidity in the room where the notification recommending the operation of the air conditioner is changed from the above level to the low temperature side and the low humidity side. Thereby, the influence of sunlight can be relieved and it can maintain so that a sensory temperature may not become high, and the person who suffers from heat stroke can be reduced.

  Furthermore, when the temperature and humidity in the room change from the level at which there is a risk of heat stroke to a high temperature and high humidity side that exceeds a predetermined temperature difference or humidity difference, the air conditioner is forcibly cooled or dehumidified. Reduce the temperature and humidity of the to a level that is less likely to cause heat stroke. In addition, if the air conditioner does not start after a predetermined time has passed since the temperature and humidity in the room reached a level that could cause heat stroke, the air conditioner is forcibly cooled or dehumidified. Then, lower the temperature and humidity in the room to a level that is less likely to cause heat stroke.

  This makes it possible to change the temperature and humidity of the room to a higher temperature and humidity, even if you are unable to change your position by yourself and you are not aware that you are sleeping in the sun in deep sleep. If the temperature at which there is a risk of suffering from heat stroke continues over time, the air conditioner can start cooling or dehumidifying operation, lowering the temperature and humidity in the room, and reducing the number of people suffering from heat stroke.

  As described above, the air conditioner of the embodiment is equipped with the control for performing the light source identification operation, the brightness stage determination operation and the human detection operation even when the operation is stopped, and the difference between the specified sunlight In addition to the crowded position, when there is a person and the room temperature or / and the room humidity deviate from the predetermined range, the operation recommendation of the air conditioner is notified.

  In general, heat stroke is likely to occur at high temperatures and high humidity. In recent years, people who suffer from heat stroke in a closed room who have a housing situation such as the wind does not enter even if the window is opened due to the influence of urbanization, or the window cannot be opened for crime prevention is increasing. Even if an air conditioner is installed, there are some people who hesitate to operate the air conditioner because of the increased awareness of power saving and the lack of electricity bills, and the problem is only getting worse.

  As a measure of the likelihood of heat stroke, WBGT: Wet-bulb temperature is proposed, and this is simply expressed as temperature and humidity. According to this, when the temperature is 30 ° C., warning is required for heat stroke when the humidity exceeds 45%, and strict warning is required when the humidity exceeds 65%. Furthermore, when the humidity exceeds 85%, it becomes a dangerous state, so it is necessary to take actions such as cooling.

  Similarly, when the humidity is 65%, caution is required when the room temperature exceeds 27 ° C., and strict caution is required when the room temperature exceeds 30 ° C. Furthermore, when the room temperature exceeds 33 ° C., it becomes a dangerous state, so it is necessary to take actions such as cooling.

  In the air conditioner according to the embodiment, even when the air conditioner is intentionally stopped by the user or stopped by control, for example, when the room temperature is 30 ° C. and the humidity exceeds 65%, the air Inform the user of a message recommending the operation of the harmonic machine. The notification method may be any method such as display, buzzer, or voice. Moreover, it is good also to notify to the housemate who exists in another room by a transmission line and a radio | wireless, Furthermore, you may notify to a visiting care provider etc. via the internet.

  In addition, the room temperature and humidity levels for notification are not limited to the above-mentioned one point. For example, points such as 25 ° C. 100% and 35 ° C. 30% are stored, and the room temperature humidity connects these points. You may make it start alerting | reporting operation | movement when it becomes a high temperature high humidity side. By doing so, the user, housemate, visiting care provider, etc. are informed that the room is in a temperature and humidity state that requires strict vigilance, and the user, housemate, or rushed visiting care staff However, heat stroke can be prevented by starting the operation of the air conditioner.

  For this reason, the air conditioner which can alert | report prevention of heat stroke and can reduce the number of people falling into heat stroke can be provided.

  Further, in the air conditioner according to the embodiment, when there is a person at the specified sunlight insertion position, the predetermined range is changed to the low temperature side and / or the low humidity side to change the air conditioner. Notify driving recommendations.

  Thereby, when there is a person in the position where sunlight is inserted, the level of room temperature humidity for reporting heat stroke prevention is lowered to, for example, a warning level, and the room temperature humidity is 27 ° C. 60%, 33 ° C. 30%. The above notification is started when the temperature is higher than the line connecting the two. By doing in this way, it can prevent that the person who does not cool in the sunlight becomes heat stroke.

  For this reason, even when there are people in the sunshine, an air conditioner that can reduce the number of people who suffer from heat stroke can be provided.

In the air conditioner of the embodiment, the room temperature or / and the room humidity are more than a predetermined temperature difference from the predetermined range or the changed predetermined range to the high temperature side and / or the high humidity side or / and the predetermined humidity. If you deviate more than the difference,
Alternatively, when the deviation from the predetermined range or the changed predetermined range continues for a predetermined time or more, the air conditioner is started to perform a cooling operation or a dehumidifying operation.

  Thereby, even when no one notices the notification, when the time during which the air conditioner does not operate from the state continues for, for example, one hour or longer, the operation of the air conditioner is forcibly started. By doing so, the user can be prevented from falling into a dangerous state of heat stroke. Also, after the notification, the room temperature humidity continues to rise, and for example, if the room temperature humidity deviates over a predetermined temperature difference or / and over a predetermined humidity difference to the high temperature and high humidity side, the operation of the air conditioner is forcibly started. To do.

  For this reason, the air conditioner which can reduce the person who falls into heat stroke can be provided.

  As described above, according to the air conditioner of the present embodiment, the image sensor is mounted, the color temperature of the light incident on the image sensor is detected, the type of the light source is identified, and the brightness stage is determined. It has a function to judge.

  Thus, as described above, an approximate color temperature is detected using an image sensor that is frequently used in digital cameras. In addition, by using the AE function, the degree of brightness is divided into a plurality of stages, and it is determined to which stage the observed brightness belongs.

  The color temperature of direct sunlight is about 5,500K, which does not change much in winter or summer. Moreover, in a day, it will be 1,900-2500K in the morning sun or sunset, and will be 6,500K in the daytime when it is cloudy. In addition, the white LED bulb that has recently seen signs of widespread use is 5,200K.

  When heating or cooling a room, whether direct sunlight is inserted through the window or not is greatly affected by the heating or cooling load. As mentioned above, the color temperature of direct sunlight is about 5,500K. It is lower than this value in the morning and evening when it does not have a significant effect on the heating or cooling load, and higher than this value when it is shaded or cloudy without direct sunlight. Become.

  In addition, the color temperature of incandescent bulbs, fluorescent lamps, and LED bulbs, which are artificial lights, is lower than this value. Thus, by measuring the color temperature in the room, it is possible to know whether direct sunlight is inserted into the room in the measuring direction or not. Furthermore, since it is possible to know the degree of direct sunlight by measuring the brightness, it is possible to control the air conditioner in consideration of the influence of sunlight on the heating or cooling load.

  In this case, if it is possible to distinguish between direct sunlight and shade, cloudy sky, and artificial light, it is not necessary to accurately determine the color temperature, and it is sufficient to experimentally determine a clear relationship between them. .

  For this reason, the air conditioner which can be controlled in consideration of the influence of sunlight can be obtained.

  Further, according to the air conditioner of the present embodiment, the air conditioner is controlled according to the identified type of the light source and the determined brightness level.

  As a result, when the type of light source is sunlight and the brightness level is brighter than a predetermined level, it is estimated that the sunlight in the room is strong, and the temperature is set to the set temperature, assuming that the sensory temperature has increased due to the sunlight. Further, it is possible to perform control to save energy during heating and maintain comfort during cooling. At this time, the amount of room temperature reduction can be adjusted according to the brightness to achieve more detailed energy savings or minimize the energy required to maintain comfort.

  For this reason, the air conditioner which can implement | achieve the energy saving at the time of heating, and the maintenance of the comfort at the time of cooling with little energy can be obtained.

  Further, according to the air conditioner described in the present embodiment, when the type of the light source is identified as sunlight, the air conditioner is controlled according to the brightness level.

  As a result, when the brightness stage is brighter than the predetermined level, it is estimated that the sunlight into the room is strong, and the temperature of the temperature is raised by the sunlight. Enhancing the circulation of indoor air, lowering the sensible temperature, and conserving energy by diffusing the air in a place with strong sunlight, which has been gathered during heating, into the room, and also reducing the blowing wind speed to warm the sun. Can be wrapped gently and quietly, and while maintaining comfort, energy can be saved.

  Therefore, it is possible to obtain an air conditioner that can be controlled with both comfort and energy saving during heating and cooling.

  Further, according to the air conditioner of the present embodiment, a mechanism capable of changing the imaging direction of the imaging device into a plurality of directions is mounted, and the type of the light source and the determination of the brightness level are determined in each imaging direction. If the type of the light source is identified as sunlight, the insertion position of sunlight into the room is specified.

  Thereby, it is possible to send the blown air toward a place where the sunlight is strong, or to blow the air away from the place, and it is possible to perform an operation with more detailed comfort and energy saving.

  For this reason, the air conditioner which can perform the operation | movement which aimed at comfort and energy saving more finely can be obtained.

  Further, according to the air conditioner of the present embodiment, the air conditioner has a human detection function for detecting the presence / absence of a person from a captured image of the image sensor, and the identification is performed when the type of the light source is identified as sunlight. The air conditioner is controlled according to whether a person is present or absent at the inserted sunlight position.

  Thus, for example, when there is a person at the sunlight insertion position during heating operation, the blower of the indoor unit is designed so that the wind speed of the air blown from the indoor unit is reduced or the wind direction is changed so as not to apply the wind And keep the sun-drifting position of the sunlight plug-in position gently and gently. In addition, since people who are in the sun are warming up in warm warmth, the room temperature may be lowered slightly from the set temperature to measure energy saving.

  If there is no person at the sunlight insertion position, control the indoor unit blower so that the wind reaches the sunlight insertion position by increasing the wind speed of the air blown from the indoor unit or changing the wind direction. And push the warmth of the sundrift into the room. In this case, the window into which sunlight is inserted absorbs solar heat and is warmed.Those who are away from the indoor window receive radiation from the window, and the temperature of the experience increases slightly. It is possible to save energy by adjusting the room temperature lower than the setting.

  During cooling operation, if there is a person at the sunlight insertion position, increase the wind speed of the air blown from the indoor unit or change the wind direction so that the wind reaches the person at the sunlight insertion position. The indoor unit blower is controlled to lower the temperature of the person in the sun. In addition, people who are in the sunlight receive glimmering sunlight, and the temperature of the sensible temperature is rising, so the degree of sunlight is judged at the brightness level captured by the image sensor, and this brightness Depending on the stage, the room temperature may be lowered from the set temperature to measure energy saving while maintaining comfort.

  If there is no person at the sunlight insertion position, control the blower of the indoor unit so that the wind speed of the air blown out from the indoor unit is reduced or the direction of the air is not applied, and the sunlight position is adjusted. Prevent hot air from spreading indoors. In this case, the window into which sunlight is inserted absorbs solar heat and is warmed.Those who are away from the indoor window receive radiation from the window, and the temperature of the experience increases slightly. The comfort may be maintained by adjusting the room temperature lower than the setting.

  For this reason, when there is a person at the insertion position of sunlight, an air conditioner that can perform an energy saving operation as much as possible while maintaining comfort can be obtained according to the absence of the person.

  Further, according to the air conditioner of the present embodiment, the operation of the built-in mechanism with a large driving sound is stopped or postponed according to the brightness level.

  Thereby, when the determined brightness level of the room is dark at night, it is determined to be sleeping, for example, the operation of the automatic cleaning mechanism of the filter, the determined brightness level of the room is Postpones until daytime brightness changes. By carrying out like this, it can prevent that the drive sound which disturbs sleep is emitted from an air conditioner during a person's sleep.

  For this reason, the air conditioner which does not disturb night sleep can be obtained.

  Further, according to the air conditioner of the present embodiment, the brightness of the display device is adjusted according to the brightness level.

  As a result, when there is no illumination at night, the brightness of the display device is set to a level at which the content of the display can be read, and the brightness of the display device is set to a level that can be read as the room brightness increases. Brighten. By doing in this way, the energy saving of a display apparatus can be aimed at.
