In addition, although the indoor environment sensor 12 shall be provided near the center part of the front panel 5, it is not restricted to this, What is necessary is just to be provided in the position which can measure indoor temperature and humidity. For example, the indoor environment sensor 12 may be provided near the air inlet 2. Moreover, the indoor environment sensor 12 may be provided outside the air conditioner. That is, the indoor environment sensor 12 may be installed at an arbitrary position in the room.

  The human body sensor 13 is provided on the front panel 5 at the center of the unit. The human body sensor 13 includes a plurality of thermopiles arranged in the vertical direction, and moves in the left-right direction to scan for each specific area. The human body sensor 13 acquires a plurality of pieces of heat distribution information for each specific region by scanning. This heat distribution information includes information on the temperature, area, and coordinates of the heat source. In addition, the specific area | region here refers to one of what divided | segmented the room in which the air conditioning apparatus was installed into several area | regions, as shown in FIG. For example, the human body sensor 13 scans in the order of region α (shaded region), region β (dot region), region γ (filled region), region δ (shaded region), and acquires heat distribution information for each region. By doing so, it is possible to acquire heat distribution information in all regions of the room.

In the description of the air conditioning apparatus according to Embodiment 1, the human body sensor 13 acquires heat distribution information. However, the present invention is not limited to this, and any sensor that can identify the position and part of the human body may be used. . For example, the air conditioning apparatus according to Embodiment 1 may be configured to acquire information on the position of the human body such as the coordinates of the position of the human body and the coordinates of the part of the human body using a high-precision camera or the like.

  Next, the configuration of the control unit 9 will be described in detail with reference to FIG.

  The control unit 9 includes a human body determination unit 91, an elapsed time measurement unit 92, a body part determination unit 93, an indoor environment determination unit 94, an indoor environment determination table storage unit 95, an operation control table storage unit 97, a performance control unit 98, and a ventilation control. The unit 99 is configured.

  The human body determination unit 91 generates background image data and thermal image data based on the heat distribution information detected by the human body sensor 13, and analyzes these image data to determine whether or not a human body exists.

  Specifically, the human body determination unit 91 acquires, from the human body sensor 13 in advance, heat distribution information in the room where the air conditioner is installed. The human body determination unit 91 generates background image data (FIG. 5A) from the heat distribution information. In addition, the human body determination unit 91 generates thermal image data illustrated in FIG. 5C based on the acquired heat distribution information after a predetermined time has elapsed since the generation of background image data. FIG. 5C shows thermal image data when a human body is present in an area scanned by the human body sensor 13, as shown in FIG. 5B. In FIG. 5 (c), the shaded shade indicates the temperature level, and the portion A (high temperature portion A) represented by the dark shaded line indicates a high temperature. Further, a portion B (low temperature portion B) or a portion C (low temperature portion C) represented by a thin oblique line is lower in temperature than the high temperature portion A and indicates a higher temperature than the corresponding portion of the background image data. Usually, since human beings are dressed, the exposed face and hands become the high temperature part A. In addition, the squares in FIG. 5C indicate coordinates and regions used for determining a part of the human body on the thermal image data. From the thermal image data in FIG. 5C, the human body determination unit 91 can obtain information on the coordinates of the heat source, the area of the heat source, and the temperature of the heat source.

  In the human body determination unit 91, a threshold A is set in advance. The human body determination unit 91 calculates a temperature difference between corresponding coordinates of the background image data and the thermal image data, and determines that a human body exists when there is a region exceeding the threshold A. When it is determined that a human body exists, the human body determination unit 91 outputs an elapsed time measurement start signal to the elapsed time measurement unit 92. Furthermore, the human body determination unit 91 outputs the generated background image data and thermal image data to the body part determination unit 93. The elapsed time measurement start signal is a signal that causes the elapsed time measurement unit 92 to start measuring elapsed time. The elapsed time indicates the time that has elapsed since the human body determination unit 91 determined that a human body exists.

  The elapsed time measurement unit 92 is a timer or the like, receives an elapsed time measurement start signal from the human body determination unit 91, and measures an elapsed time from the time when the elapsed time measurement start signal is received. Further, the elapsed time measuring unit 92 outputs the elapsed time to the air blowing control unit 99 every predetermined time. The predetermined time here may be an interval shorter than the range of elapsed time included in the operation control table described later.

  The body part determination unit 93 determines a part of the human body using the thermal image data obtained from the human body determination unit 91. Specifically, the body part determination unit 93 has a threshold value A of the temperature of an exposed portion such as a human head or a hand, and a region belonging to the range of the threshold value A on the thermal image data The hand is determined (FIG. 5C). Moreover, the body part determination part 93 has the information regarding the area of the part of the human body displayed on thermal image data. Therefore, it is possible to distinguish an exposed portion such as a head or a hand based on the information on the area and the temperature. Note that the body part determination unit 93 similarly determines the part of the human body based on the area of the region other than the threshold A and adjacent to the region of the threshold A and having a certain amount of heat (threshold B). For example, in the example of FIG. 5C, the threshold B is the low temperature part B and the low temperature part C. Moreover, the body part determination part 93 distinguishes a torso and a leg according to the areas of the low temperature part B and the low temperature part C. With this configuration, the body part determination unit 93 can distinguish the head, torso, and feet regardless of the posture of the user. The body part determination unit 93 outputs coordinates (body part determination information) related to a part of the human body such as the head, legs, and torso to the air blow control unit 99. In addition, let the human body sensor 13, the human body determination part 91, and the body part determination part 93 be a human body detection means.

  The indoor environment determination unit 94 determines the indoor environment level based on information indicating the room temperature and humidity detected by the indoor environment sensor 12 and an indoor environment determination table stored in an indoor environment determination table storage unit 95 described later. To do. The indoor environment level is an index corresponding to the user's temperature.

  The indoor environment determination table storage unit 95 stores an indoor environment determination table shown in FIG. FIG. 6A is an example of an indoor environment determination table when the humidity is constant. In the indoor environment determination table, the indoor environment level, the room temperature, the humidity, and the sensory temperature are associated with each other. For example, room environment level 1 (LV.1) is associated with room temperature “26 ° C. or higher”, humidity “from 50% to less than 60%”, and body temperature “low”. That is, when the room temperature in the room where the air conditioner is installed is 26 ° C. or higher and the humidity is from 50% to less than 60%, the room environment determination unit 94 determines that the room environment level is 1. In addition, it is determined that the user's sensible temperature at this time is low. The indoor environment determination table is created so that the indoor environment level and the sensible temperature increase as the room temperature increases. FIG. 6B is an example of an indoor environment determination table when the room temperature is constant. In the indoor environment determination table of FIG. 6 (b), the indoor environment level, room temperature, humidity, and sensory temperature are associated with each other, as in FIG. 6 (a). Created to rise. As described above, the indoor environment determination table storage unit 95 stores an indoor environment determination table in which the combination of temperature and humidity, the indoor environment level, and the sensory temperature are combined. The indoor environment determination table is stored in advance in the indoor environment determination table storage unit 95 based on the designer's experiment data and the like. In the description of FIG. 6, the indoor environment determination table is described as being divided between the case where the humidity is constant and the case where the temperature is constant. However, the indoor environment determination table is not limited to this and may be a single indoor environment determination table. In the indoor environment determination table, the indoor environment level and the sensory temperature are associated with the temperature and humidity. However, the indoor environment determination table is not limited to this, and the indoor environment level and the sensory temperature are associated with either temperature or humidity. You may comprise so that temperature may be matched.

  The indoor environment determination unit 94 outputs information indicating the determined indoor environment level to the performance control unit 98. Note that the indoor environment determination unit 94 may be configured to determine the indoor environment level based on either temperature or humidity information.

  The performance control unit 98 refers to an operation control table in the operation control table storage unit 97 described later, receives an indoor environment level from the indoor environment determination unit 94, and selects a ventilation control pattern. The performance control unit 98 outputs the selected ventilation control pattern to the ventilation control unit 99. In addition, the ventilation control pattern here means the wind direction, the air volume, the fluctuation, and the combination thereof that change with the elapsed time. Fluctuation refers to a wind that is close to natural wind, and is less effective in cooling the human body than normal ventilation, but achieves high comfort.

  The operation control table storage unit 97 stores an operation control table shown in FIG. The operation control table is a table in which the indoor environment level is associated with the air blowing control pattern. In addition, each blowing control pattern (Pattern 1 to Pattern 3) includes a row of wind direction, air volume, and fluctuation in each column of elapsed time “0 to 5 minutes”, “5 to 15 minutes”, and “15 to 25 minutes”. Conditions are associated. For example, the indoor environment level received from the indoor environment determination unit 94 is LV. In the case of 1, the performance control unit 98 selects the blow control pattern (pattern 1) and outputs the blow control pattern (pattern 1) to the blow control unit 99 described later.

  In the operation control table, the elapsed time is divided by 0 to 5 minutes, 5 to 15 minutes, and 15 to 25 minutes. However, the operation control table is not limited to this, and may be divided by any elapsed time. For example, it may be divided at intervals of 3 minutes such as 0-3 minutes, 3-6 minutes, 6-9 minutes. Further, the elapsed time of the operation control table is 25 minutes at the maximum value, but is not limited to this, and an arbitrary value can be set. For example, the maximum value may be 30 minutes.

  The operation control table is programmed by the designer based on the experimental data. The operation control table is set for each indoor environment level so that the user can obtain a more comfortable feeling by combining the wind direction, the air volume, and the fluctuation with time.

  The air blowing control unit 99 receives the elapsed time from the elapsed time measuring unit 92, the body part determining information from the body part determining unit 93, and the air blowing control pattern output from the performance control unit 98, and based on the air blowing control pattern. The fan 6, the heat exchanger 7, the left and right wind direction plates 10, and the upper and lower vanes 11a and 11b are controlled. For example, in the row of the elapsed time “0 to 5 minutes” of the ventilation control pattern (pattern 1), the wind direction “body”, the air volume “weak”, and the fluctuation “present” are associated. When the output elapsed time is “0 to 5 minutes”, the air blow control unit 99 uses the wind direction as the trunk, weakens the air volume, and fluctuates so that the fan 6, the heat exchanger 7, the left and right The wind direction plate 10 and the upper and lower vanes 11a and 11b are controlled. In the following description, the fan 6, the heat exchanger 7, the left and right wind direction plates 10, and the upper and lower vanes 11a and 11b are referred to as air blowing means.

  The information input unit 14 receives external information by a user's remote control operation. The external information is, for example, setting of air blowing, cooling, heating, setting of room temperature, setting of timer, and the like. In addition, the air conditioning apparatus which concerns on Embodiment 1 shall set ventilation. Moreover, the information input part 14 should just be the structure which can receive various setting information from a user, and may be operated not only by a remote control but by the operation button (not shown) installed in the air conditioning apparatus. Good.

  Here, the relationship between the indoor environment level, the wind direction, and the air volume in the operation control table will be described with reference to FIG. FIG. 8A is an example of experimental data regarding the user's thermal sensation. Moreover, FIG.8 (b) is an example of the experimental data about a user's comfort feeling. In the following description, the comfort feeling indicates a level at which the user feels comfortable, and the thermal feeling indicates the level of heat and cold felt by the user. In addition, it is assumed that the user feels comfortable in the order of “foot> torso> face” and the airflow “weak> medium = strong”. Further, it is assumed that the wind direction is “torso> face> foot” and the airflow is “strong> medium> weak” in order of warmth and cooling. In addition, only when the user feels hot, by setting the wind direction to “face”, the thermal sensation of the user is effectively transitioned to a cooler one and the comfortable period to a comfortable one. Further, it is assumed that the indoor environment has a room temperature of 29 ° C. and a humidity of 55% (indoor environment level LV.2).

  In the elapsed time of 0 to 5 minutes, the air blowing control unit 99 performs the LV. In accordance with the air flow control pattern of the elapsed time 0 to 5 minutes in line 2, air flow control is performed under the conditions of the wind direction “body”, the air volume “medium”, and the fluctuation “none”. Since the elapsed time of 0 to 5 minutes is immediately after the start of air blowing, the thermal sensation is high (elapsed time of 0 to 5 minutes in FIG. 8A). Also, due to heat, the comfort is present in an uncomfortable area (elapsed time 0 to 5 minutes in FIG. 8B). Therefore, it is important to eliminate the heat, and an effective wind direction “torso” is selected to reduce the thermal sensation. The indoor environment level is LV. Because it is 2, the air volume is set to “medium” to prevent overcooling.

  Since the thermal sensation starts to approach the optimum value at the elapsed time of 5 to 15 minutes, the air blowing control unit 99 controls the air flow with the “foot” having a low effect of providing a comfortable feeling as the wind direction in order to prevent the human body from being too cold. . However, to prevent an increase in thermal sensation, the air volume remains “medium”.

  In the elapsed time of 15 to 25 minutes, the thermal sensation is sufficiently lowered (around the elapsed time of 15 minutes in FIG. 8A). Therefore, emphasis is placed on comfort rather than thermal sensation, and control is performed so that wind is applied to the “foot”, which is a part where comfort is more sustained. In order to prevent the human body from being too cold, the air volume is set to “weak”. In this way, the operation control table is configured to change the portion to which the wind is applied and the air volume according to the elapsed time so that the user's comfort and thermal feeling are optimized. By configuring the operation control table in this way, the user's ever-changing feeling of comfort and thermal feeling can be automatically brought close to the optimum state. The air blow control pattern of the operation control table according to the first embodiment is not limited to this, and the combination of the wind direction and the air volume can be changed as appropriate based on the designer's know-how and experimental data. In addition, although description about fluctuation was abbreviate | omitted in description of FIG. 8, you may add fluctuation to a ventilation control pattern. In other words, the thermal feeling is emphasized, the fluctuation is set to “none” when the human body is desired to be cooled, and the fluctuation is set to “exist” when the comfort feeling is important.

  Next, operation | movement of the air conditioning apparatus which concerns on Embodiment 1 is demonstrated using FIG. FIG. 9 is an operation flowchart of the air-conditioning apparatus according to Embodiment 1. In the following description, the room temperature is 32 ° C. and the humidity is 55%. Moreover, the operation control table memorize | stored in the indoor environment table memory | storage part shall be shown to Fig.6 (a).

  In ST1, the user turns on the power of the air conditioner via the information input unit 14 using a remote controller or the like, and selects the air blowing mode.

  In ST2, the human body sensor 13 scans the room and acquires heat distribution information. In addition, the human body sensor 13 outputs the acquired heat distribution information to the human body determination unit 91. In addition, the human body determination unit 91 generates background image data and thermal image data based on the heat distribution information detected by the human body sensor 13, and analyzes the image data to detect the presence or absence of a human body. When it is determined that there is a human body, the human body determination unit 91 outputs an elapsed time measurement start signal to the elapsed time measurement unit 92. In addition, the human body determination unit 91 outputs the background image data and the thermal image data to the body part determination unit 93. Note that the human body determination unit 91 repeats the operation for determining the presence or absence of a human body until it is determined that there is a human body.

  In ST3, the elapsed time measuring unit 92 receives the elapsed time measurement start signal from the human body determining unit 91 and starts measuring the elapsed time. Further, the measured elapsed time is output to the air blowing control unit 99 every predetermined time.

  In ST4, the indoor environment sensor 12 measures indoor temperature and humidity. In addition, the indoor environment sensor 12 outputs information indicating temperature and humidity to the indoor environment determination unit 94. In this example, since the room temperature is 32 ° C. and the humidity is 55%, the indoor environment sensor 12 outputs information indicating the temperature of 32 ° C. and the humidity of 55% to the indoor environment determination unit 94.

  In ST5, the indoor environment determination unit 94 refers to the indoor environment determination table (FIG. 6A) of the indoor environment determination table 95 and corresponds to the indoor temperature of 32 ° C. and the humidity of 55% received from the indoor environment sensor 12. Search the indoor environment level. In the indoor environment determination table, the indoor environment level corresponding to a temperature of 32 ° C. and a humidity of 55% is LV. 3. Therefore, the indoor environment determination unit 94 sets the LV. 3 is output to the performance control unit 98.

  In ST6, the body part determination unit 93 receives the background image data and the thermal image data from the human body determination unit 91, and determines the coordinates of the face, feet, and torso. The body part determination unit 93 outputs the coordinates of the face, feet, and torso to the air blowing control unit 99 as body part determination information.

  In ST7, the performance control unit 98 refers to the operation control table (FIG. 7) in the operation control table storage unit 97, and from the indoor environment determination unit 94 to the indoor environment level LV. 3 is selected, and the ventilation control pattern (pattern 3) corresponding to LV.3 is selected. The performance control unit 98 outputs information on the selected ventilation control pattern (pattern 3) to the ventilation control unit 99.

  In ST8, the ventilation control unit 99 receives the elapsed time from the elapsed time measurement unit 92, the body part determination information from the body part determination unit 93, and the information of the ventilation control pattern (pattern 3) from the performance control unit 98, Control means. In this example, it is assumed that the user has just turned on the power in the room where the air conditioner is installed, and the elapsed time is 0 minutes. In this example, since the elapsed time is 0 minute, the performance control unit 98 controls the air blowing means so that the wind direction is “face”, the air volume is “strong”, and the fluctuation is “none”.

  In ST9, when the elapsed time acquired from the elapsed time measurement unit 92 exceeds 25 minutes, the blower control unit 99 returns to ST2 and causes the human body sensor 13 to sense again. The air conditioner repeats ST2 to ST9 until the end operation is performed. On the other hand, the ventilation control part 99 returns to ST8, when the received elapsed time is less than 25 minutes. In ST8, the performance control unit 98 selects the air blowing control pattern in the operation control table again according to the indoor environment level acquired from the indoor environment determining unit 94, and causes the air blowing control unit 99 to continue the air blowing control.

  The end operation is executed when the power is turned off based on a user operation. In FIG. 9, the end operation is the next step of ST9, but it can be performed at any step as long as the power is turned off.

  In addition, the example which added fluctuation to the ventilation control pattern of the operation control table which concerns on Embodiment 1 was shown. Hereinafter, the fluctuation control will be described with reference to FIG. FIG. 10 is a diagram for explaining fluctuation control of the air-conditioning apparatus according to Embodiment 1. In FIG.

  FIG. 10 shows the number of rotations (rpm) of a fan motor (not shown) for driving the fan 6 on the vertical axis and the time (s) on the horizontal axis. In the fluctuation control, the fan motor is controlled based on a sine wave as shown in FIG. In addition, the sine wave has a wave (hereinafter referred to as a small wave) having a short period of constant air blowing from the air conditioner and a low wind speed. Based on this sine wave, a wave with a longer period and a medium wind speed than a small wave (hereinafter referred to as a medium wave) and a wave with a longer period and a greater wind speed than a small wave (hereinafter referred to as a medium wave) To add a peak wave to a sine wave. The peak wave only needs to be about once every 20 to 30 s, and the peak wave is as short as possible. The peak wave has a width shorter than a quarter cycle at most. By setting the width of the peak wave to ¼ period or less, the user can feel the peak wave clearly even in a wave with a short period of constant air blowing from the air conditioner and a low wind speed. it can. The tactile sensation is very good if it is preferably 1/8 period or less.

  As a specific example, as shown in FIG. 10, the base sine wave is a gentle sine wave with a period of 120 s, and the wind speed when measured at a position 3 m ahead of the air conditioner is about 0.2 m / s. Like that. For example, the air conditioner controls the air flow so that the average rotational speed is 800 rpm and the fluctuation range that is the difference between the maximum value and the minimum value of the sine wave is 100 rpm. A peak wave that increases the rotation speed by about 200 rpm with a width of about 10 to 20 s is added to the sine wave as a large wave that appears several times in one cycle. In addition, as a medium-sized wave that appears several times in one cycle, a peak wave that adds about 10 to 20 s in width and increases the rotation speed by about 100 rpm is added. When the peak wave is received, the wind speed near the user's position increases instantaneously by about 0.4 m / s to 0.8 m / s. Further, small waves of about 0.1 m / s to 0.2 m / s appear every 10 to 20 times / minute due to the sine wave. A large wave takes a time of about 2 s and reaches its peak by increasing the rotation speed from the sine wave. The time at the peak of a large wave is about 2 s. A medium-sized wave reaches a peak at about 6 s by increasing the rotational speed from a sine wave. Further, the time at the peak of the medium-sized wave is about 10 s.

  In the description of the air conditioner according to Embodiment 1, the elapsed time indicates the time that has elapsed since the human body determination unit 91 determines that a human body is present. It may be an elapsed time from an arbitrary time point after the power is turned on. For example, the elapsed time measuring unit 92 may start measuring the elapsed time from the time when the air conditioner is turned on. Similarly, the elapsed time of the ventilation control pattern may indicate the elapsed time from the time when the air conditioner is turned on.

  As described above, the air-conditioning apparatus according to Embodiment 1 performs the air blowing control based on the operation control table in which the portion to which the wind according to the elapsed time is applied is set, so that the user changes the operation mode. And can give the user a feeling of comfort.
