Description

  The present invention relates to an air conditioner that notifies the deterioration of the indoor temperature and humidity environment.

  In general, heat stroke is likely to occur at high temperatures and high humidity, and hypothermia is likely to occur at low temperatures. In addition, the sense of heat and cold becomes duller than the year, and the response to heat and cold is delayed, and heat stroke and hypothermia are more likely to occur. If there is a family living together in such a state, the family living together can drive the air conditioner to bring the room to an appropriate temperature and humidity, thereby preventing heat stroke and hypothermia.

  However, with the advent of an aging society, elderly people living alone are increasing, and for heat stroke, even if the windows are opened due to the influence of urbanization, there is no wind, There are an increasing number of people who have housing conditions such as being unable to open the room, and who develop heatstroke in a closed room.

  In addition to this, there is a tendency to increase power saving awareness in response to the worsening energy situation, and an increasing number of people endure heat. As a result, an increasing number of people develop heat stroke without operating the air conditioner even when the room temperature increases.

  Various techniques have been proposed to deal with such situations. For example, JP2011-099622, JP2002-024957, JP04-151445A, JP2007-280167A.

  In Patent Literature 1, in an air conditioning system, an air conditioner is connected to an external network, and various information (for example, weather forecast, temperature, humidity) is acquired from the external network. The acquired information can be displayed on the remote controller in real time. At the same time, in the communication between the air conditioner and the remote controller, the low power consumption communication means / method is applied, so that the power consumption of the remote controller necessary for communication with the air conditioner can be suppressed. Thereby, an air conditioning system capable of providing information to the user suitably while suppressing power consumption is disclosed. In addition, as an example of using an external temperature sensor, there is a description that heat stroke can be prevented by attaching the sensor to the elderly body.

  In Patent Document 2, based on the biological information estimated by the human body heat model, the risk determination means objectively determines the risk of causing a biological disorder due to abnormal body temperature, and it is determined that there is a risk of causing the biological disorder. In such a case, a body temperature monitoring device is disclosed in which the safety of the subject is ensured in advance by issuing an alarm from the alarm device and prompting evacuation.

  In patent document 3, in the terminal device of the centralized monitoring device that monitors air conditioning equipment such as buildings and factories, the upper and lower limit values for monitoring are created based on the indoor temperature and humidity target value and the upper and lower limit deviation values of the indoor temperature and humidity. This eliminates the need to manually reset the upper and lower limit values. It is also disclosed that an alarm can be generated when the air conditioner is ON, and an unnecessary alarm can be prevented when the air conditioner is OFF.

  In Patent Document 4, a thermal pixel image is generated based on detection of an infrared sensor, and the image is analyzed to determine what a fire or abnormality is. When it is determined that a fire or abnormality is detected, a communication unit is used. An air conditioner for informing the effect from home appliances is disclosed.

As shown in FIG. 1, the air conditioner A includes an indoor unit 100, an outdoor unit 200, and a remote controller Re. The indoor unit 100 and the outdoor unit 200 are connected via a refrigerant pipe (not shown), and air-conditions the room (the air-conditioned space) where the indoor unit 100 is installed 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 control receiver Q of the indoor unit 100 in accordance with the operation. The contents of the 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 signals.

  The imaging means 120 is located at the center in the left-right direction of the indoor unit 100 and is exposed to the outside. Details of the imaging unit 120 will be described later.

As shown in FIG. 2, the imaging means 120 is installed in a fixed portion 111 that extends in the left-right direction below the dew tray 110.

  The imaging means 120 is installed such that the optical axis P (see FIG. 7A) of a lens (not shown) faces downward by a depression angle ε (see FIG. 7A) with respect to the horizontal plane. The room in which the machine 100 is installed can be appropriately imaged.

  When the blower fan 103 shown in FIG. 2 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. Further, 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 to air-condition the room.

  FIG. 3 is a configuration diagram including control means of the air conditioner. The control unit 130 comprehensively controls the operation of the air conditioner A according to image information input from the imaging unit 120, sensor signals input from various sensors (not shown), and the like.

  The storage unit 140 includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. Then, the program stored in the ROM is read out by a CPU (Central Processing Unit) of the control means 130 and expanded in the RAM, and various processes are executed.

  The blower fan drive unit 103 a is a motor that rotates the blower fan 103 at a predetermined rotation speed in accordance with a command from the control unit 130. The left / right wind direction plate drive unit 104a is a motor that rotates the left / right wind direction plate 104 (see FIG. 2) in the left / right direction in accordance with a command from the control means 130. The vertical wind direction plate drive unit 105a is a motor that rotates the vertical direction plate 105 (see FIG. 2) in the vertical direction in accordance with a command from the control unit 130.

<Configuration of control means>
As shown in FIG. 3, the control unit 130 includes a human body detection unit 131, a coordinate conversion unit 132, a movement distance calculation unit 133, an activity amount calculation unit 134, a movement locus estimation unit 135, and a sensory temperature estimation unit 136. And a drive control unit 137.

  The human body detection unit 131 detects the position of the human body based on the image information input from the imaging unit 120 every predetermined time, and outputs the detection result to the coordinate conversion unit 132. Incidentally, the detection result described above includes the coordinates of the detected face center of each human body (coordinates on the screen) and the size of the face (length in the vertical direction on the screen).

  The coordinate conversion unit 132 converts the above-described human body detection result from a coordinate system on the screen specified by the number of pixels of the imaging screen to a coordinate system in the real space, and outputs the result to the movement distance calculation unit 133. Incidentally, the information output from the coordinate conversion unit 132 to the movement distance calculation unit 133 includes X, Y, and Z coordinate values of the human body center.

  The movement distance calculation unit 133 calculates the movement speed for all possible combinations of the position of each human body input from the coordinate conversion unit 132 and the position of the human body calculated in the past (for example, 1 sec before), Each is given an identification symbol and output to the activity amount calculation unit 134.

  The activity amount calculation unit 134 calculates an activity amount based on each movement distance calculated by the movement distance calculation unit 133. The “activity amount” means the metabolic rate [W / m 2] per unit surface area of the human body and has a positive correlation with the moving speed of the human body. The activity amount calculation unit 134 associates the calculated activity amount with the above-described identification symbol, and outputs it to the movement trajectory estimation unit 135 and the sensory temperature estimation unit 136.

  The movement trajectory estimation unit 135 compares the amount of activity corresponding to the assumed combination of the position of the human body detected this time by the human body detection unit 131 and the position of the human body detected in the past, and the comparison result Based on the above, the movement trajectory of the human body is estimated.

  Then, the movement trajectory estimation unit 135 reflects the estimated movement trajectory in the activity amount of each human body, associates the activity amount with the current position of each human body, and outputs it to the drive control unit 137.

  The sensible temperature estimation unit 136 estimates an average sensible temperature based on the information input from the activity amount calculation unit 134 and sensor signals input from various sensors, and outputs the estimated value to the drive control unit 137. Incidentally, the average value of the sensible temperature is a value obtained by averaging the sensible temperature of each occupant in the air-conditioned room.

  The information corresponding to the various sensor signals described above is, for example, the room temperature detected by a room temperature sensor (not shown) or the room humidity detected by a humidity sensor (not shown).

  The drive control unit 137 includes information input from the movement trajectory estimation unit 135 (that is, an activity amount distribution in the air-conditioned room), an average value of the sensory temperature input from the sensory temperature estimation unit 136, and the sensor signal described above. Based on the above, the parameters of the air conditioning control are changed.

Note that the “air conditioning control parameters” include the rotational speed of the blower fan 103, the rotation angle of the left and right wind direction plates 104, and the rotation angle of the upper and lower wind direction plates 105. As shown in FIG. 3, the blower fan drive unit 103a, the left / right wind direction plate drive unit 104a, and the up / down wind direction plate drive unit 105a are driven in response to a command signal input from the drive control unit 137.
<About imaging area>
FIG. 4A is an explanatory diagram (side view) of an imaging region in the vertical direction imaged by the imaging means. As shown in FIG. 4A, a straight line passing through a focal point 120a of a lens (not shown) included in the imaging unit 120 and perpendicular to the wall surface W on which the indoor unit 100 is installed (the indoor side is positive) is defined as the Z axis. . Further, the distance from the back surface of the indoor unit 100 to the focal point 120a of the lens is assumed to be Δd.

  Further, a straight line that passes through the origin O located behind the focal point 120a of the lens by a distance Δd and is perpendicular to the horizontal plane (the lower side of the indoor unit 100 is positive) is taken as the Y axis.

  The imaging means 120 is installed so that the optical axis of the lens faces downward from the horizontal plane by a depression angle ε (see FIG. 7A). Note that the upper end of the field of view of the imaging means 120 that expands in a fan shape in a side view is substantially coincident with the Z axis.

  In the present embodiment, the imaging region includes a horizontal plane that passes through the focal point 120a of a lens (not shown) and four virtual planes a1, a2, a3, a4, and a5 that pass through the focal point 120a and have a predetermined inclination with respect to the horizontal plane. Is divided into 5 in the vertical direction.

  That is, a region sandwiched between the horizontal plane and the virtual plane a1 is A1, and a region sandwiched between the virtual plane an and the virtual plane a (n + 1) is A (n + 1) (where n = 1,..., 4).

  The above-described regions A1,..., A5 are used when the drive control unit 137 controls the angle of the vertical wind direction plate 105 according to the detection result of the human body.

  FIG. 4B is an explanatory diagram (plan view) of the imaging region in the left-right direction imaged by the imaging means. In FIG. 4B, the indoor unit 100 is omitted.

  A straight line passing through the origin O and perpendicular to the Y axis and the Z axis (the left side toward the indoor unit 100 is positive) is taken as the X axis.

  The viewing angle of the imaging unit 120 is, for example, 60 ° in plan view. The control unit 130 drives the imaging unit driving unit (not shown) to reciprocate the imaging unit 120 in the left-right direction around a rotation shaft (not shown). That is, the control unit 130 reciprocates the imaging unit 120 in the order of left → center → right → center → left →... Every predetermined time (for example, 30 sec).

  In the present embodiment, the imaging region is divided into 10 in the left-right direction by 10 virtual planes b1,..., B10 that are perpendicular to the X axis and have a predetermined inclination with respect to the plane including the Z axis. That is, an area sandwiched between the virtual plane b (n−1) and the virtual plane b (n) is Bn (where n = 1,..., 10).

  The regions B1,..., B10 are used when the drive control unit 137 controls the angle of the left and right wind direction plates 104 according to the detection result of the human body.

  With respect to the regions B1,..., B10 spreading in a fan shape in plan view, the central angle θ2 of each fan shape is, for example, 15 °.

  As shown in FIG. 4B, the left area is composed of areas B1,..., B4. The left area is an area on the left side of the three areas imaged by the imaging unit 120 toward the indoor unit 100. The sum (15 ° × 4 = 60 °) of the central angles θ2 of the regions B1,..., B4 is equal to the viewing angle of the imaging unit 120.

  The central region is composed of regions B4, ..., B7. The central area is an area located in the center among the three areas imaged by the imaging unit 120. Incidentally, the region B4 belongs to the left region and also belongs to the central region. As described above, the region B4 located at the right end of the left region and the region B4 located at the left end of the central region are made common, thereby preventing a human body from being missed.

  The right region is composed of regions B7,..., B10. For the same reason as the above-described region B4, the region B7 is set to belong to the central region and also to the right region.

  By sequentially capturing images in the order of left region → center region → right region (or the reverse order) by the imaging unit 120, it is possible to capture a region having an angle θ1 (for example, 150 °) in a plan view in the air-conditioned room.

Incidentally, the air-conditioned room is virtually divided into 50 (= 5 × 10) areas by the areas A1,..., A5 continuous in the vertical direction and the areas B1,. The control means 130 adjusts the angles of the left and right wind direction plates 104 and the upper and lower wind direction plates 105 according to the activity distribution in these 50 regions.
<Outline of air conditioning control processing>
FIG. 5 is an explanatory diagram showing an outline of the air conditioning control process executed by the control means. Time t0 shown in FIG. 5 is the start time of air conditioning control based on human body detection. FIG. 5 shows that time elapses from left to right.

  As described above, the control unit 130 reciprocates the imaging unit 120 to sequentially image the air-conditioned room in the order of left region → center region → right region → center region → left region →... (See the imaging region G1). ).

  When the air conditioning control is started at time t0, the control unit 130 images the left region (region B1,..., B4: see FIG. 4B) 30 times, for example, every 1 sec. Then, using the imaging result, the number, position, and amount of activity of the occupants in the left area are calculated and stored in the storage means 140 (see area determination α1L: reference G2).

Next, at time t1, the control means 130 rotates the imaging means 120 to the right, and images the central area (area B4,..., B7: see FIG. 4B) 30 times, for example, every 1 sec. Then, using the imaging result, the number, position, and amount of activity of the occupants in the central area are calculated and stored in the storage means 140 (section determination α1M: see symbol G2).
Next, at time t2, the control unit 130 further rotates the imaging unit 120 to the right, for example, captures the right region (region B7,..., B10: see FIG. 4B) 30 times every 1 sec. The number of people in the area, the position, and the amount of activity are calculated and stored in the storage means 140 (section determination α1R: see symbol G2).

  As described above, the control unit 130 rotates the imaging unit 120 clockwise to sequentially capture the left, center, and right regions, and uses the image information acquired by the imaging, such as the amount of activity of the human body existing in each region. (First imaging: see symbol G3).

  Further, the control means 130 reads out the number, position, and amount of activity of the occupants calculated for each of the left, center, and right areas from the storage means 140, and the number, position, And the amount of activity is calculated (final determination β1: see symbol G4). Details of the human body detection process will be described later.

  Further, the control means 130 rotates the left and right wind direction plates 104 and the upper and lower wind direction plates 105 in full width until the first detection process is completed (see symbols G6 and G7).

  When the first imaging (left, center, and right regions) is completed, the control unit 130 turns on a display lamp (not shown) according to the detected number of occupants (see symbol G5). For example, the control means 130 has three indicator lamps (not shown) arranged at predetermined positions of the indoor unit 100, one when the occupant is one and two when the occupant is 2-3. If there are 4 or more people, 3 are lit.

  Thereby, the user (that is, the resident) can easily confirm that the control means 130 appropriately detects the resident.

  Furthermore, the control means 130 updates the parameters for controlling the left and right wind direction plates 104 (see symbol G6) and the up and down wind direction plates 105 (see symbol G7) according to the first processing result. To control. Although omitted in FIG. 5, the control unit 130 also controls the rotational speed of the blower fan 103 in accordance with the first processing result.

  And the control means 130 performs the 2nd human body detection process in the time t3-t5, performing the wind direction control according to the 1st human body detection process. When performing the human body detection process for the second time, the control unit 130 rotates the imaging unit 120 counterclockwise and sequentially images the right, center, and left regions (see reference numeral G3).

  Here, the image information of the right region imaged for the first time of the second time uses the image information of the right region imaged for the first time (30 images) as it is. Thereby, the air-conditioning room can be imaged continuously and smoothly while reciprocating the imaging means 120.

Air-conditioning control using the results of the second and subsequent imaging (right, center, and left regions) is the same as when performing the first imaging described above. As described above, the control unit 130 sequentially acquires the image information of the right, center, and left regions, executes the human body detection process, and reflects the detection result in the air conditioning control.
<Air conditioning control process using human detection results>
FIG. 6 is a flowchart showing the flow of processing performed by the control means. 6 is started when, for example, an operation mode for performing human body detection is selected by the user, and a predetermined command signal is input from the remote controller Re to the remote controller receiver Q (see FIG. 1) of the indoor unit 100. Is done.

  6 corresponds to the time t0 shown in FIG. 5 described above, and the imaging unit 120 is in a direction to image the left region in the air-conditioned room.

  In step S <b> 101, the control unit 130 sets the value of n to 1 (n = 1) and stores it in the storage unit 140. Incidentally, the value of n is sequentially incremented every time image information is input from the imaging means 120 (S111).

  In step S <b> 102, the control unit 130 receives input of image information from the imaging unit 120. The image information input from the imaging unit 120 is, for example, an A / D converted digital signal. The image information includes the number of pixels (vertical direction / horizontal direction) for specifying a pixel and a pixel value.

  In step S <b> 103, the control unit 130 detects the number and positions of occupants existing in the air-conditioned room from the image information input from the imaging unit 120.

  First, the control unit 130 detects the head and shoulders of the human body using the image information input from the imaging unit 120. The detection processing can be executed by edge extraction processing and pattern matching, for example.

  Next, the control means 130 calculates the position of the face center for each detected human body, and calculates the size (vertical length) D0 of the head. Then, the control unit 130 stores the calculation result in the storage unit 140 in association with the time information at the time of detection and predetermined identification information.

  Further, the control unit 130 stores the detected number of human bodies (that is, the number of people) and the time information at the time of detection in the storage unit 140 in association with each other.

  Next, in step S <b> 104 of FIG. 6, the control unit 130 executes a coordinate conversion process.

  FIG. 7A is an explanatory diagram showing the relationship between the optical axis P and the vertical plane S. FIG. As shown in FIG. 7A, the optical axis P of the imaging unit 120 has a depression angle ε with respect to the horizontal plane. The vertical plane S is a virtual plane that is perpendicular to the optical axis P and passes through the center of the face of the occupant. The distance L is the distance between the focal point 120a of a lens (not shown) included in the imaging means 120 and the face center of the occupant.

  As described above, the distance between the wall surface W on which the indoor unit 100 is installed and the focal point 120a of the lens is Δd.

  FIG. 7B is an explanatory diagram illustrating a relationship between an image captured on the image plane and the occupants existing in the real space. An image plane R shown in FIG. 7B is a plane that passes through a plurality of light receiving elements (not shown) included in the imaging unit 120. The vertical angle of view γy corresponding to the calculated head size D0 is expressed by the following (Formula 1). Incidentally, the angle βy [deg / pixel] is an average value of the angle of view (y direction) per pixel, and is a known value.

  Then, the distance L [m] from the focal point 120a of the lens (not shown) to the center of the face is as follows, assuming that the average length of the face in the vertical direction is D1 [m] (known value) ( It is expressed by Formula 2). As described above, the depression angle ε is an angle between the optical axis of the lens and the horizontal plane.

  FIG. 7C is an explanatory diagram showing the relationship between the distance L from the focal point of the lens to the center of the face and the field angles δx and δy.

  Assuming that the angles of view in the X direction and Y direction from the center of the image plane R to the center of the face on the image are δx and δy, respectively, these are expressed by the following (Equation 3) and (Equation 4). Here, xc and yc are positions of the human body center in the image (X coordinate, Y coordinate in the image). Tx [pixel] is the horizontal size of the imaging screen, and Ty [pixel] is the vertical size of the imaging screen, each of which is a known value.

  Therefore, the position of the human body center in the real space is expressed by the following (Formula 5) to (Formula 7).

  Returning again to FIG. 6, the description will be continued. In step S <b> 105, the control unit 130 executes the noise removal process 1. That is, the control means 130 is a false detection (that is, noise) when the position of the human body center (X, Y, Z) described above is a value that is not assumed when the occupant is properly detected. The image information corresponding to this is deleted.

  For example, when Y ≦ 0 (normally, the human body center is not positioned above the horizontal plane), or when Y ≧ 2 (normally, the human body center is not positioned below the floor surface). ) Image information is deleted. An example of the noise is a person shown on a television screen or a poster.

  Thus, by deleting image information in the case of erroneous detection at an early stage, it is possible to reduce the amount of calculation when performing the movement trajectory estimation process (S109).

  Next, in step S <b> 106, the control unit 130 calculates the movement distance for all possible combinations of the position coordinates of the human body remaining after the process of step S <b> 105 and the position information of the human body imaged in the past. For example, as a detection result shown in FIG. 9A, the human body is at positions A and B at a predetermined time, the human body is at position C in the next imaging, and the human body is in positions D and E in the next imaging. To do.

  When the position C is detected by the current imaging, the control unit 130 calculates the movement distance for all possible combinations between the positions A and B detected in the past and the position C detected this time. That is, the control unit 130 calculates a distance LAC when the occupant moves from position A to position C and a distance LBC when moving from position B to position C. In this embodiment, since imaging is performed every 1 sec, the distances LAC and LBC can be regarded as moving speeds (the same applies to other moving distances).

  In this way, the control unit 130 calculates the moving speed for all possible combinations of the one or more human bodies detected this time and the one or more human bodies detected in the past. At this time, the correspondence relationship between the human body detected this time and the human body detected in the past is not known.

  Next, in step S <b> 107, the control unit 130 executes noise removal processing 2. That is, the control unit 130 excludes combinations whose movement distance is equal to or greater than a predetermined value from the estimation target of the movement trajectory.

  FIG. 8 is a graph showing the relationship between the movement speed of the occupants and the amount of activity. The horizontal axis of the graph shown in FIG. 8 is the moving speed [m / s] of the occupant, and the vertical axis is the activity [W / m2] of the occupant. As shown in FIG. 8, that is, the amount of activity is 1 (the occupants are almost stationary) in the region where the moving speed is less than 0.5 m / s. Moreover, in the area | region where a moving speed is 0.5 m / s or more, activity amount increases substantially proportionally to a moving speed.

  Incidentally, the information shown in FIG. 8 (correspondence between the movement speed and the amount of activity) is stored in advance in the storage means 140 (see FIG. 3).

  In addition, since it is rare for the occupant to move at a speed of 1.5 [m / s] or more, the area is designated as an invalid area (shaded area in FIG. 8). Therefore, in step S107, the control unit 130 excludes a combination (combination of the current detection result and the past detection result) having a moving distance of 1.5 [m / s] or more from the processing target.

  In this way, by removing combinations that satisfy the predetermined condition in advance, it is possible to prevent a mistake with another human body that could not be detected in the past. Moreover, the calculation load at the time of performing the movement locus estimation process described later can be reduced.

  Next, in step S108, the control means 130 calculates an activity amount. That is, the control means 130 refers to the information (see FIG. 8) indicating the correspondence relationship between the movement speed and the activity amount, and corresponds to each movement distance calculated in step S106 (however, remaining in the process of S107). To calculate the amount of activity.

  At this point in time, the correspondence between the human body detected this time and the human body detected in the past is not known.

Next, in step S109, the control means 130 executes a movement trajectory estimation process (tracking). That is, the control means 130 estimates the actual movement trajectory of the occupant from among a plurality of candidate movement trajectories. In the example shown in FIG. 9A, the following two types of movement trajectories of the detected human body can be considered.
1. The resident (first person) has moved from position A to position C.
2. The occupant (second person) moved from position B to position C.

  The control means 130 specifies the combination that minimizes the corresponding amount of activity among the assumed combinations of the position of the human body detected this time and the positions of one or more human bodies detected in the past.

  That is, the control means 130 determines which of the above 1 and 2 is correct by comparing the amount of activity MAC corresponding to the distance LAC and the amount of activity MAC corresponding to the distance LBC. As described above, in the present embodiment, since imaging is performed every 1 sec, the distances LAC and LBC can be regarded as moving speeds. Further, from FIG. 8, the moving speed and the amount of activity have a positive correlation. Therefore, the amount of activity corresponds directly to the length of the travel distance.

  For example, when the distance LAC and the distance LBC shown in FIG. 9A are compared, the distance LAC is shorter (LAC <LBC). Therefore, when the activity amount MAC is compared with the activity amount MBC, the activity amount MAC is smaller (MAC <MBC).

  The control means 130 estimates that the movement trajectory that gives a relatively small amount of activity is the actual movement trajectory of the occupant. That is, the control unit 130 estimates that the first human body has moved from the position A to the position C (see FIG. 9B), and stores the position (A → C) and the activity amount MAC in association with each other. Stored in 140.

  Thus, by estimating that the shortest moving trajectory is the actual moving trajectory, the moving trajectory can be identified appropriately and easily.

  Incidentally, the human body corresponding to the second human body existing at the position B in the previous imaging is not detected in the current imaging (see FIG. 9B). In this case, the control unit 130 associates the position B with the imaging time and stores the position B in the storage unit 140 as a candidate for the subsequent movement trajectory estimation process. In this way, candidates that may have been missed this time are left until a predetermined number of times (for example, five times) from the next time.

  When the human body is detected at the positions D and E shown in FIG. 9A in the next imaging, the control means 130 compares the magnitudes of the activity amounts corresponding to the distance LCD, the distance LCE, the distance LBD, and the distance LBE, respectively. Here, the position B described above is read from the storage unit 140 as a candidate for the movement trajectory estimation process.

  As shown in FIG. 9A, the length of the moving distance is LCD <LCE <LBE <LBD. Accordingly, the corresponding amount of activity is MCD <MCE <MBE <MBD. Then, the control unit 130 stores a movement trajectory that gives a relatively small activity amount, that is, C → D and the activity amount MCD in the storage unit 140 in association with each other.

  Then, it is estimated that the first human body has moved as A → C → D (see FIG. 9B). Therefore, the control unit 130 excludes the movement of B → D and the movement of C → E from the estimation target of the movement locus. As a result, the control means 130 estimates that the second human body has moved in the position B → □ → E (see FIG. 9B).

  In this way, the control means 130 detects the occupant each time image information is input from the imaging means 120 and estimates the movement trajectory.

  When estimating the movement trajectory, it is preferable to estimate the movement trajectory in order from the human body with the smallest amount of activity until the past detection, with respect to one or a plurality of human bodies detected in the past. Here, “the amount of activity until the previous detection” may be the amount of activity associated with the movement from the previous time to the previous time, or the activity weighted as it approaches the present in consideration of the movement before that. It may be the sum of quantities.

  In general, humans cannot suddenly change their operating speed. For example, it is highly likely that a human body that has not moved in the past does not move even now or has a relatively short moving distance even if there is a movement. In addition, the human body that has moved in the past is likely to continue moving.

  By estimating the movement trajectory in order from the human body with the smallest amount of activity, the past movement history can be reflected in the activity amount, and the movement trajectory can be estimated more efficiently and appropriately.

  As another example, as shown in FIG. 10A, the human body is detected at positions A and B at a predetermined time, the human body is detected at positions C and D at the next imaging, and the human body is positioned at the next imaging. Assume that E and F are detected.

  Further, the distances LAD, LBD, LDE, and LDF shown in FIG. 10 are each 1.5 m or more (that is, the moving speed is 1.5 m / s or more).

  In this case, the combination of A → D, B → D, D → E, and D → F in which the moving speed is 1.5 m / s or more in the noise removal process 2 (see FIG. 6) in step S107 described above is as follows: Excluded from moving trajectory candidates.

  Accordingly, the control means 130 uses the same method as in FIG. 9A to move the first person as A → C → E and the second person as B → □ → E. Estimate (see FIG. 10B). Further, the human body detected at the position D is estimated to be a human body (third person) different from the two (see FIG. 10B) and stored in the storage means 140.

  Note that steps S102 to S110 shown in FIG. 6 are performed using the image information of one time out of the N times of imaging executed at times t0 to t1 (imaging of the left region: see G3) shown in FIG. Equivalent to.

  Next, in step S110 of FIG. 6, the control means 130 determines whether or not n = N. N is a preset value (for example, N = 30), and is the number of times the room is imaged in each of the left, center, and right regions.

  When n = N (S110 → Yes), the process of the control unit 130 proceeds to step S112. On the other hand, if n = N is not satisfied, that is, if n <N (S110 → No), the process of the control unit 130 proceeds to step S111. In step S111, the control means 130 increments the value of n and returns to the process of step S102.

  Next, in step S112, the control means 130 executes the region determination process α as follows (corresponding to the region determination α1L shown in FIG. 5).

  That is, the control means 130 sets the number of people in the room as the number of human bodies whose detection rate is 20% or more among human bodies lost in the middle and human bodies that have been traced to the end. In the example shown in FIG. 10B, the number of times of detection by the first person is 27 out of 30 imaging, and the detection rate is 90%. Similarly, the detection rate for the second person is 50%, and the detection rate for the third person is 10% (<20%).

  Therefore, the control means 130 considers that the third person has been erroneously detected (or has left the air-conditioned room on the way) and excludes it from processing.

  In addition, regarding the human body that could not be detected 5 times in succession among the 30 times of imaging, the control means 130 considers that it was a false detection (or has left the air-conditioned room on the way) and is excluded from processing. .

  In addition, the control unit 130 sets the position of each occupant as the position that can be detected last in the area (the left area in this case).

  Further, the control unit 130 calculates the sum by weighting the activity amount corresponding to the movement trajectory estimated in step S109 as it is closer to the current time, and stores the sum in the storage unit 140 in association with the position of the occupant.

  Next, in step S113, the control unit 130 determines whether all of the left, center, and right regions have been imaged N times a predetermined number of times. When all the left, center, and right regions are imaged N times a predetermined number of times (S113 → Yes), the process of the control unit 130 proceeds to step S115. On the other hand, when at least one of the left, center, and right regions is not captured, the process of the control unit 130 proceeds to step S114.

  In step S114, the control unit 130 rotates the imaging unit 120 by a predetermined angle, starts imaging the next area, and returns to the process of step S101. For example, when imaging of the left region is completed, the control unit 130 rotates the imaging unit 120 to the right and starts imaging of the central region.

  In step S115, the control means 130 executes the final determination β as follows (corresponding to the first final determination β1 shown in FIG. 5).

  That is, the activity amounts acquired in the left, center, and right regions are overlapped in association with the respective positions. If the human body is detected in both the regions B4 and B7 (see FIG. 4B) where the detection regions overlap, and the human body interval is within a predetermined distance (for example, 2 m), the control means 130 is the same. It is determined that the person is a person.

  In this case, the shorter elapsed time from the detection is adopted, and the number of duplicates is reduced.

  As described above, the control unit 130 can accurately grasp the distribution of the activity amount by associating the activity amount in the air-conditioned room (weighted with respect to the activity amount from the past to the present) with the position information in step S115.

  Further, the control unit 130 is divided into 50 (= 5 × 10) divided into the above-described five regions in the vertical direction (see FIG. 4A) and the ten regions in the horizontal direction (see FIG. 4B). ) And the above-described activity amount distribution are stored in the storage unit 140 in association with each other.

  Next, in step S116 of FIG. 6, the control means 130 executes a wind direction / air volume control process. That is, the control unit 130 refers to the distribution of the activity amount in the 50 regions described above, and controls the angles of the left and right wind direction plates 104 and the upper and lower wind direction plates 105 according to the distribution. Further, the rotational speed of the blower fan 103 is adjusted in accordance with the distribution of the activity amount in the air-conditioned room, the average value of the sensible temperature, and signals input from various sensors.

  Incidentally, when performing the cooling operation, the control means 130 intensively blows cold air toward a region where the activity amount is large. On the other hand, when the heating operation is performed, the control unit 130 intensively blows warm air toward a region where the amount of activity is small.

  Fig.11 (a) is explanatory drawing (side view) of the wind direction control of an up-down direction according to distribution of activity amount. When performing the cooling operation, if the amount of activity in the area A1 in FIG. 4A is relatively large in the vertical direction, the control means 130 controls the wind direction as follows. That is, the control means 130 rotates the up-and-down air direction plate 105 so that the cool air is blown in the direction indicated by reference sign c1 in FIG.

  Similarly, when the activity amount in the region An (n = 2,..., 5) in FIG. 4A in the vertical direction is large, the control means 130 causes the vertical wind direction to blow cool air in the direction indicated by reference sign cn. The plate 105 is rotated.

  On the other hand, when the heating operation is performed, if the activity amount in the region An (n = 1,..., 5) in FIG. The vertical wind direction plate 105 is rotated so as to blow the hot air in the direction indicated by the symbol hn.

  FIG.11 (b) is explanatory drawing (plan view) of the wind direction control of the left-right direction according to distribution of activity amount. When performing the cooling operation, if the amount of activity in the region B1 in FIG. 4A is relatively large in the left-right direction, the control means 130 performs the following control. That is, the control means 130 rotates the up-and-down air direction plate 105 so that the cold air is intensively blown in the direction indicated by reference numeral f1 in FIG.

  Similarly, when the amount of activity in the region An (n = 2,..., 10) in FIG. 4A in the left-right direction is large, the control unit 130 focuses on the cold air in the direction indicated by the symbol fn. The left and right wind direction plates 104 are rotated.

  On the other hand, when the heating operation is performed, when the activity amount in the region An (n = 1,..., 10) in FIG. The right and left wind direction plates 104 are rotated so as to blow the hot air mainly in the direction indicated by the symbol fn.

Thus, the direction of the up / down wind direction plate 105 and the left / right wind direction plate 104 is controlled according to the distribution of the activity amount in the air conditioning room and the air conditioning mode.
<Effect>
According to the air conditioner A according to the present embodiment, the human body detection is performed using the image information input from the imaging unit 120, thereby increasing the detection probability of the occupant.

  For example, in the case of detecting an occupant by using a face detection function as in the technique described in Patent Document 1 described above, the detection of the occupant can be performed even if a high-resolution imaging unit is used to perform face detection. Probability will be low. In this case, even if the room is imaged every predetermined time (for example, 1 sec) using the imaging unit, the movement trajectory of the occupant cannot be estimated appropriately, and the result of face detection is not effectively reflected in the air conditioning control.

  On the other hand, according to the air conditioner A according to the present embodiment, the human body (the upper body of the occupant) regardless of the direction of the occupant's face and whether or not the backlight is backlit. It can be detected with high probability. Thus, the detection probability can be increased by using human body detection, and the movement locus can be estimated (tracked) appropriately without specifying an individual.

  Further, when performing human body detection, it is possible to cope with a lower resolution than when performing face detection. Therefore, the cost for the imaging unit 120 can be reduced.

  Further, in the present embodiment, the control means 130 sequentially specifies a combination that minimizes the corresponding amount of activity among the combinations assumed based on the position of the human body detected this time and the positions of a plurality of human bodies detected in the past. The movement trajectory was estimated.

  As described above, the movement locus can be appropriately and efficiently estimated by sequentially specifying the movement locus from a combination having a small amount of activity (that is, a combination having a short movement distance per unit time).

  In this embodiment, when the human body center (X, Y, Z) is located within a predetermined range, or when the moving speed of the human body is 1.5 m / s or more, the control unit 130 excludes these from the processing target. (S105, S107: see FIG. 6).

  As a result, erroneous detection can be prevented, and the amount of calculation required for the subsequent movement trajectory estimation process can be reduced.

  In addition, according to the present embodiment, the imaging unit 120 is reciprocated in the left-right direction to image the entire room, and the image information of the right region captured by rotating the imaging unit 120 clockwise is imaged next. Is rotated as it is counterclockwise and used as it is when imaging (the same applies to the left area). Therefore, it is possible to continuously and smoothly image the air-conditioned room while reciprocating the imaging unit 120.

  Further, according to the present embodiment, by estimating the movement trajectory of the human body (tracking is performed), the detected amount of activity of each human body can be detected continuously in time. Therefore, it is possible to appropriately estimate the detected amount of activity and temperature of each human body, and to appropriately reflect them in the air conditioning control in association with the position of the human body.

For example, the rotational speed of the blower fan 103, the angle of the left and right wind direction plates 104, and the upper and lower wind direction plates 105 so that warm air is intensively blown toward a human body having a small amount of activity (low sensible temperature) during heating operation. Control the angle. This makes it possible to reduce power consumption and save power by lowering the set temperature according to the average value of the sensation temperature while maintaining the comfort of the occupants whose sensation temperature is lower than the average value of the sensation temperature. .
<Modification>
As described above, the air conditioner A according to the present invention has been described in the above embodiment, but the embodiment of the present invention is not limited to this, and various modifications can be made.

  For example, in the above-described embodiment, the case where the movement trajectory is estimated based on the activity amount has been described, but the present invention is not limited to this. That is, the movement trajectory may be estimated by directly using the movement distance of the human body.

  As described above, the movement distance of the human body per predetermined time (that is, the higher the movement speed) is positively correlated with the amount of activity (see FIG. 8). Therefore, among the possible combinations of the position of the human body detected this time and the position of one or a plurality of human bodies detected in the past, the combination with the minimum corresponding movement distance is detected this time. The trajectory can be estimated by sequentially specifying each of one or a plurality of human bodies.

  Further, when estimating the movement trajectory, for one or a plurality of human bodies detected in the past, the movement trajectory may be estimated in order from a human body having a smaller movement distance (movement speed) until the past detection. As a result, the movement locus can be estimated efficiently and appropriately by reflecting the past operation history.

  In addition, by using the detection result by the human body detection unit 131, the density of people in the air-conditioned room (the number of persons existing per unit area) can be obtained. The sensible temperature of the occupant varies depending on the above-described density in addition to the amount of activity (has a positive correlation with the density). In this case, the control means 130 calculates the density distribution of the human body existing in the room every time the air-conditioned room (left, center, right area) is imaged, and reflects the density on the sensible temperature of the occupant.

  For example, when performing heating operation, when it is estimated that the sensible temperature of the occupant is relatively high due to the density, the control unit 130 reduces the set temperature so as to offset the increase in the sensible temperature, and compresses it. Reduce the rotational speed of the machine (not shown). As a result, the power consumption can be reduced while maintaining the comfort of the occupants.

  Moreover, the control means 130 may adjust the rotation angle of the up-and-down wind direction plate 105 and the left and right wind direction plate 104 to blow air so as to avoid a region where the density of the human body is high.

  In the above-described embodiment, the case where the left, center, and right regions are sequentially imaged by rotating the imaging unit 120 (viewing angle 60 °) and the region of 150 ° is imaged in plan view has been described. Not limited to.

  When the imaging unit 120 has a sufficient viewing angle, the human body detection process can be performed without rotating the imaging unit 120. The movement trajectory estimation processing method in this case can be performed by the same method as in the above embodiment.

  Moreover, although the said embodiment demonstrated the case where the imaging means 120 was installed in the fixing | fixed part 111 of the indoor unit 100, it is not restricted to this. That is, the imaging means 120 may be installed at other locations in the indoor unit 100 as long as the inside of the air-conditioned room can be imaged.

  Further, in each of the above embodiments, the case where the rotation speed of the blower fan 103, the angle of the left and right wind direction plates 104, and the angle of the upper and lower wind direction plates 105 are changed according to the result of the movement trajectory estimation process has been described. Not exclusively. That is, at least one of the rotational speed of the blower fan 103, the angle of the left and right wind direction plate 104, and the angle of the upper and lower wind direction plate 105 may be changed.

  Further, the set temperature of the air conditioner A is appropriately changed according to the result of the movement trajectory estimation process, and the rotational speed of a motor (not shown) installed in the compressor (not shown) is changed accordingly. May be.

  Next, an air conditioner according to Embodiment 2 of the present invention will be described.

  In the second embodiment, FIGS. 12 to 20 show an air conditioner that issues an alarm when a room is at a temperature and humidity that are likely to suffer from heat stroke and hypothermia, and issues an alarm that prompts some countermeasures. It explains using. FIG. 12 shows the relationship between WBGT, temperature, and humidity. FIG. 13 is a front part of a schematic control flowchart of the temperature / humidity alarm function of the air conditioner according to the second embodiment. FIG. 14 is a middle part of a schematic control flowchart of the temperature and humidity alarm function of the air conditioner according to the second embodiment. FIG. 15 is a latter part of the schematic control flowchart of the temperature / humidity alarm function of the air conditioner according to the second embodiment. FIG. 16 is a display explanation part of the remote controller. FIG. 17 shows an operation explanation unit of the remote controller. FIG. 18 is an explanatory diagram of the function selection order of the remote controller.

  WBGT (wet bulb temperature) is an index that incorporates three factors: humidity, radiant heat, and temperature, which have a large effect on the heat balance of the human body, and uses the values of dry bulb temperature, wet bulb temperature, and black bulb temperature. It is calculated as follows.

Outdoor WBGT = 0.7 x wet bulb temperature + 0.2 x black bulb temperature + 0.1 x dry bulb temperature Indoor WBGT = 0.7 x wet bulb temperature + 0.3 x black bulb temperature WBGT is the working environment Is standardized as JIS Z 8504 in Japan and ISO 7243 globally with respect to “thermal stress of workers based on the WBGT (wet bulb black bulb temperature) index”.

If the temperature reference is 31 degrees or higher, the danger level is high, so avoid going out as much as possible and stay in a cool room.
(28-31 degrees) When you go out of caution, avoid the sun and pay attention to room temperature rise indoors.
(25 to 28 degrees) Warning Take sufficient rest regularly when you perform dangerous exercises or intense work that occurs in moderate or higher life activities.
(Less than 25 degrees) Caution Danger caused by strong daily activities Generally, the risk is small, but there is a risk that it occurs during intense exercise or heavy work.

  WBGT: Wet-bulb temperature is proposed as a measure of the likelihood of heat stroke, and this can be expressed simply as temperature and humidity as shown in FIG. Has been done. 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.

  The remote controller Re of the air conditioner according to the second embodiment has a temperature / humidity alarm function for informing when the room becomes hot and hypothermic, when the temperature and humidity are high, and encouraging the operation of the air conditioner. It can be set by button operation. On the other hand, the air conditioner is provided with control software for controlling the execution of the temperature / humidity alarm function.

  As shown in FIG. 17, the temperature / humidity alarm function is performed by pressing the function selection button 10 provided on the remote controller Re, and moving the function marks 22a to 22h on the remote controller display unit 20 in the order of the arrows in FIG. The feed button 16 is selected in sequence, the temperature / humidity alarm function mark 22d is displayed and selected, and the setting button 17 is pressed to set. When canceling this function, the temperature / humidity alarm function mark 22d is displayed and selected in the same manner as described above, and the function is canceled by pressing the cancel button 18.

  When the air conditioner A is operated by the user, the air conditioner A operates according to the setting as a matter of course. When the air conditioner A is stopped by the user, the air conditioner checks whether the air conditioner itself is in a stopped state by manual operation or timer operation in step S10 in FIG. Then, the control of the temperature / humidity alarm function is terminated.

  In step S15, it is checked whether or not the temperature / humidity alarm function is set by the remote controller Re. If not, the process proceeds to step 35, the control of the temperature / humidity alarm function is terminated, and if the temperature / humidity alarm function is set. Proceed to step S20. In step S20, a predetermined number of days after the manual operation of the remote control or the on / off operation with a timer that allows the user to change the on / off time is performed, or after the room temperature and humidity falls out of the strict warning range. Check whether it is within (for example, 2 weeks).

  When the temperature / humidity alarm function has been set, or when other operations of the air conditioner have been performed for more than a predetermined number of days, the use period of the air conditioner A and the time when there is a strong risk of heat stroke have passed. In step 35, the control of the temperature / humidity alarm function is terminated. In step S20, if the temperature / humidity alarm function is set, or if another operation of the air conditioner is performed, the process proceeds to step S21.

  In step S21, the room temperature / humidity monitoring system is entered, and the apparatus enters a standby mode in which the room temperature / humidity is periodically measured. The waiting time is set to 17 minutes, for example, so that the indoor temperature / humidity is within the alert range shown in FIG. With this setting, when measuring indoor temperature and humidity, which will be described later, the measurement interval is 20 minutes, together with the necessary 3 minutes of familiarity between the temperature and humidity measuring unit and the room air.

  If the measurement interval is too long, it will not be possible to properly respond to changes in the indoor temperature and humidity, and if the measurement interval is too short, it will take too much energy to rotate the blower in the familiar operation with the indoor air prior to measurement, so it is too short It is better to avoid the measurement interval. In the present embodiment, in the region where WBGT is lower than 28 degrees (the lower limit of the strict warning level), it is considered sufficient to perform the measurement three times in one hour, and the measurement interval is set to 20 minutes.

  In this case, when the risk of heat stroke is higher than WBGT of 28 degrees (the lower limit of the strict warning level), the measurement interval may be shortened so that an appropriate response can be made to changes in indoor temperature and humidity.

  After 17 minutes have passed in step S21, the process proceeds to step S22, where the blower fan 103 is instructed to perform super-fine wind operation, the blower fan 103 is operated, the indoor air is circulated through the indoor temperature / humidity detector, and the process proceeds to step S25. . In step S25, it is checked whether or not it is within 3 minutes from the start of the ultra-fine wind operation.

  If it is within 3 minutes from the start of the ultra-fine wind operation in step S25, it is determined that the indoor temperature / humidity detection unit temperature / humidity is not sufficiently close to the indoor temperature / humidity, and the ultra-fine wind operation is continued. Wait for 3 minutes so that the temperature / humidity of the detection unit approaches the room temperature / humidity sufficiently.

  When 3 minutes have passed since the start of the ultra-fine wind operation in step S25, it is determined that the temperature / humidity of the room temperature / humidity detection unit has sufficiently approached the room temperature / humidity, and the process proceeds to step S26 to measure the room temperature / humidity. Then, the process proceeds to step S27, the operation of the blower is stopped, and the state of the air conditioner A that is the intention of the user is approached.

  Next, the process proceeds to step S30 in FIG. 14 to check whether the room temperature / humidity is within the strict warning temperature / humidity range of heat stroke and hypothermia. If not, it is determined that the room temperature / humidity is not a severe warning level for heat stroke and hypothermia, and the process returns to step S10 in FIG. 13 via E to continue monitoring the room temperature / humidity, and every 20 minutes. Steps S10 to S30 are repeated.

  In the air conditioner of the embodiment, the strict warning temperature and humidity range can be raised and lowered within a range of several degrees. This is because there is a difference between the temperature and humidity detected by the air conditioner and the temperature and humidity around the occupant. Is not very large, and the difference is greater if the airflow is not flowing properly. The flow of air between the air conditioner and the occupant varies greatly depending on the installation position of the air conditioner and the location of the occupant and the location of the furniture, and accordingly, the temperature and humidity detected by the air conditioner, This is because the difference between the temperature and humidity around the occupants varies so much that it cannot be ignored, and this is because the air conditioner is appropriately controlled in consideration of this difference.

  When the room temperature / humidity is in the severe warning temperature / humidity range of heat stroke and hypothermia in step S30, the process proceeds to step S40, and it is checked whether there is a person in the room. If there is an occupant, the process proceeds to steps S46, S47, and S51, and the timers for 30 minutes, 5 minutes, and 3 minutes, which will be described later, are started, and the process proceeds to S52 to instruct the super-fine wind operation again. Resume. This is a measure in preparation for the next measurement of indoor temperature and humidity, and as described above in the description of step 25, is performed in order to adjust the temperature of the temperature and humidity detection means of the air conditioner to the indoor temperature and humidity. is there. Then, the process proceeds to step S53 to notify / transmit that the indoor temperature / humidity is within the strict warning range.

  If there is no occupant in step S40, the process proceeds to step S45, and it is checked whether or not a function for issuing a temperature / humidity alarm is set even when there is no occupant. This is because temperature / humidity alarms are reported and transmitted without relying on the detection results of the human body detection means, such as when it is always known that there is a person in the room or when the person in the room is often in the blind spot of the camera. It is a method to make full use of the temperature and humidity alarm function by using it when you want to.

  If the temperature / humidity alarm function is not set when there is no occupant in step S45, the process returns to step S10 in FIG. 13 via E to continue monitoring the indoor temperature / humidity. When the temperature / humidity alarm function is set, as described above, the timers start counting in steps S46, S47, and S51, and the super-wind operation is resumed in S52. Further, as will be described in detail in the third embodiment, an alarm operation is instructed at a portion corresponding to step S52, the air conditioner is operated in an appropriate operation mode such as air blowing, cooling, dehumidification, heating, etc. It is also effective to induce heat in a direction with less risk of heat stroke and hypothermia.

  The means / method for notifying / transmitting the temperature / humidity alarm described above may be any means / method such as display, buzzer, sound, and video. 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. Further, the duration of the display, buzzer, sound, video, etc. may be intermittent or continuous until the above notification / transmission stop instruction is given, or may be intermittent or continuous for the first tens of seconds, You may use properly according to a means and a method, and may combine these.

  Next, proceeding to step S55, instructions such as air blow operation start, cooling operation start, heating operation start, temperature / humidity alarm stop by manual operation of the remote controller or on / off operation with a timer that allows the user to change the on / off time, etc. Check if there was. When there is manual operation of the remote control, it is assumed that the person in the room has taken action for the temperature / humidity alarm, and when there is an instruction such as driving by a timer, the indoor temperature / humidity environment is improved. , The process returns to step S10 in FIG. 13 via E, the state of the air conditioner is checked in steps S10, S15, and S20, and the temperature / humidity alarm function is terminated or continued.

  In step S55, if there is no instruction such as manual operation of the remote control or start of air blowing operation, cooling operation start, heating operation start, temperature / humidity alarm stop by a timer, it is determined that the temperature / humidity alarm is not noticed, and the temperature / humidity is repeated. The process proceeds to step S60 to notify and transmit an alarm, and it is checked whether or not 3 minutes have elapsed since the start of the 3-minute timer in step S51. If three minutes have not elapsed, the process returns to step S55 to repeat the check for manual operation of the remote controller.

  During this time, the super-wind operation is continued in accordance with the instruction in step S52 so that the next measurement of the room temperature and humidity is appropriately performed. After the elapse of 3 minutes in step S60, the process proceeds to step S61 to measure the temperature and humidity in the room, and then proceeds to step S62 to instruct to stop the operation of the blower during the ultra-fine wind operation to stop the ultra-fine wind operation. In S63, the temperature / humidity alarm notification / transmission is temporarily stopped.

  Next, in steps S65, S70, and S75, in the same procedure as steps S30, S40, and S45, in step S65, it is checked whether the room temperature / humidity is within the strict warning temperature / humidity range of heat stroke and hypothermia, and step S70. In step S75, it is checked whether or not a function for issuing a temperature / humidity alarm is set even when there is no occupant.

  When there is a resident in step S70, the process proceeds to step S85, and it is checked whether or not 5 minutes have elapsed since the start of the 5-minute timer in step S47. This is because the temperature and humidity in the room is in the strict warning temperature and humidity range, so that the temperature and humidity alarm is temporarily interrupted in order to repeat the temperature and humidity alarm, and in the embodiment, this interruption time is set to 2 minutes. A 5-minute timer was used to time 2 minutes from the time-up of the 3-minute timer.

  In step S75, if the temperature / humidity alarm function when there is no occupant is set, the process proceeds to step S80, and further, it is checked whether the temperature / humidity alarm is set to be notified / transmitted only for the first time. To do. Here, when the temperature / humidity alarm is set to be notified / transmitted only for the first time, it is assumed that the temperature / humidity alarm function is automatically set when there is no occupant.

  This is to notify and send out the temperature / humidity alarm only once for the first time as a precaution when the temperature / humidity in the room falls within the strict warning range. -Stops repeated transmissions, and saves energy for notifying / transmitting temperature / humidity alarms each time.

  If the temperature / humidity alarm is set to be notified / transmitted only at the first time in step S80, the temperature / humidity alarm is already notified / transmitted in step S53. First, the process returns to step S10 in FIG.

  If the temperature / humidity alarm is not set to be notified / transmitted only at the first time in step S80, the temperature / humidity alarm is repeatedly notified when the room is in the severe warning temperature / humidity range even when there is no occupant. In order to transmit, the process proceeds to step S85, and as described above, the interruption time for repeatedly informing / transmitting the temperature / humidity alarm is entered.

  If the 5-minute timer has not expired in step S85, the process proceeds to step S95, and it is checked whether there has been a manual operation of the remote controller or the like as in step S55. If there is a manual operation or the like, the process returns to step S10 via E as in step S55, and the indoor temperature and humidity are continuously monitored. If there is no manual operation, the process returns to step S65 to repeat the temperature / humidity alarm and repeats steps S65, S70, S75, S80, S85, S95, and the temperature / humidity alarm interruption time elapses. wait.

  If the 5-minute timer has expired in step S85, the process proceeds to step S90 to check whether the 30-minute timer has expired. While the 30-minute timer does not expire in step S90, the process returns to step S47 via B, and alternately repeats the notification and transmission of the temperature / humidity alarm for 3 minutes and the interruption for 2 minutes, to the occupant or / and outside. Repeatedly notify / transmit temperature / humidity alarm.

  In this way, I received a temperature / humidity alarm, but even if I forget to deal with it because of other things, I will remember that I will deal with it again by receiving another temperature / humidity alarm. The temperature and humidity in the room can be changed from the strict warning range to the safe side by operating the machine.

  When the 30-minute timer expires in step S90, 30 minutes have passed since the activation of the 30-minute timer in step S46, and there is no response such as manual operation of the remote control even if a temperature / humidity alarm is repeatedly issued / transmitted during that time. If there is no occupant, the process returns to step S10 in FIG. 13 via E to continue monitoring the temperature and humidity in the room.

  In this way, even if it is determined that there is no occupant once, while the indoor temperature and humidity continue to be in the warning range of heat stroke, the temperature and humidity alarm every 5 minutes Repeated 30 minutes of notification / transmission and interruption, even if the temperature / humidity alarm notification / transmission is overlooked, the temperature / humidity alarm will be issued steadily until it is out of the warning range of heat stroke. Therefore, appropriate measures to prevent heat stroke can be taken.

  As described above, the air conditioner according to the embodiment includes the human body detection unit and the temperature or / and humidity measurement unit, and the temperature or / and the indoor temperature or the human body detected and measured while the air conditioning operation is stopped. When the occupant is in a predetermined range where the occupant may suffer from heat stroke or hypothermia, a function of notifying this and / or starting the operation of the air conditioner is provided.

  As a result, even when the air conditioner is intentionally stopped by the user or controlled, the air conditioner is turned off when the room temperature is 30 ° C. and the humidity exceeds 65%, for example, at the cooling time. Inform the user of a message (temperature / humidity alarm) recommending driving. The notification means and method may be any means such as display, buzzer, sound, and video. In addition, it may be possible to transmit to a housemate in another room by transmission line or wirelessly, and further, a mobile phone terminal of a family member who is out or an outside welfare person via a wireless communication network such as the Internet. It may be sent to the

  Also, the room temperature and humidity levels for notification are not limited to the above one point. For example, the lower boundary points shown in FIG. 12, such as 25 ° C. 100%, 35 ° C. 35%, etc. May be stored, and the notification operation may be started when the room temperature humidity is higher than the line connecting these points.

  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 It is possible to prevent heat stroke by welfare personnel such as starting air conditioners.

  In the heating season, the body temperature can be adjusted by the amount of clothing, so the control is more complicated than when preventing heat stroke.For example, the amount of clothing is estimated according to the outside air temperature, In combination with the amount of activity, the recommended heating temperature is automatically set, the range where the room temperature is lower than the predetermined value is set as a strict warning range, and when the room temperature falls to this range, the driving recommendation notification is performed. Also good.

  In addition, the air conditioner may be operated instead of or in addition to the notification. In this case, the temperature and humidity in the room changes in a safer direction, and the occupant is in the heat stroke or hypothermia. The risk of falling into

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

  In the air conditioner of the embodiment, the remote controller of the air conditioner has a function of changing the predetermined range.

  Thus, for example, if the difference between the temperature and humidity detected by the air conditioner in normal cooling and heating operation and the temperature and humidity around the occupant is large, the predetermined range is set to the high temperature and high humidity side. If the difference is felt that the difference is small, the predetermined range is changed to the low temperature and low humidity side.

  As a result, when the temperature of the occupant reaches a temperature range that may cause heat stroke or hypothermia more appropriately, the temperature around the occupant is more appropriately determined. And by starting the operation of the air conditioner, it is possible to prevent the occupants from falling into heat stroke or hypothermia.

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

  Moreover, the air conditioner of the embodiment performs human body detection based on image information from the imaging means.

  In general, as a human body detecting means for detecting the presence or absence of an occupant, an infrared sensor is frequently used because of its low cost and failure, apart from accuracy. The main ones are pyroelectric infrared sensors and thermopiles, which are used not only in air conditioners, but also in monitoring equipment and safety devices, and there is no doubt about their usefulness.

  However, the pyroelectric infrared sensor makes it difficult to distinguish between the human body and the background when the background temperature approaches the body temperature, and in the thermopile, the human body melts into the atmosphere as the ambient temperature approaches the body temperature. Will become difficult. Therefore, it is necessary to limit the usage in consideration of these points, and software and hardware countermeasures that complement these points are indispensable.

  In the air conditioner of the embodiment, since the human body detection is performed based on image information from the imaging means, the room temperature, the wall, and the floor temperature are close to the body temperature, even in a situation where the occupant is likely to suffer from heat stroke, A human body is reliably detected, and this is notified or / and the operation of the air conditioner is started. Thereby, even in the summer when heatstroke frequently occurs, it is possible to accurately detect the human body and prevent the occupants from suffering from heatstroke.

  In winter, human body detection is not hindered by warm air or heat radiation from the heater, so the accuracy of human body detection will not be reduced, and reliable detection of human bodies throughout the year will notify dangerous conditions. By starting the operation of the air conditioner, it is possible to prevent in advance the risk of falling into heat stroke or hypothermia.

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

  Further, the air conditioner of the embodiment can be operated by manual operation on the control device or by a timer that allows the user to change the on / off time of the timer even after the notification or / and the operation of the air conditioner is started. When the cutting operation is not added, the notification or / and operation is repeated a plurality of times with the notification or / and operation interruption.

  As a result, if no operation is performed after the temperature / humidity alarm is issued despite being in the strict warning range of heat stroke or hypothermia, the occupants may not be aware of the temperature / humidity alarm. Because it is strong, it repeats the temperature and humidity alarm as well as the snooze function of the alarm clock (in the example, when the compressor is operated, it is transmitted every 6 minutes, and when the compressor is not operated, it is transmitted every 5 minutes) In order to stop the temperature and humidity alarm, some operation must be performed on the air conditioner, which inevitably takes action to avoid heat stroke or hypothermia, thereby preventing heat stroke or hypothermia. it can.

  For this reason, the air conditioner which can alert | report prevention of heat stroke and hypothermia, and can reduce reliably the person who falls into heat stroke and hypothermia can be provided.

  The air conditioner according to the embodiment may be based on information transmitted from the indoor unit or / and remote controller of the air conditioner or / and from the indoor unit or / and remote controller of the air conditioner. This is done from a notification terminal installed in the room, an external mobile phone, a mobile information terminal such as a smartphone, or a personal computer.

  As a result, the transmission function normally provided in the air conditioner (lighting or blinking of the indicator lamp, ringing of the buzzer, notification by voice (including synthesized voice), transmission to other rooms via transmission line, to other places via the Internet Can be used to send heat prevention and hypothermia prevention information at low cost without changing the control software. it can.

  For this reason, it is possible to provide an air conditioner that can notify the prevention of heat stroke and hypothermia and reduce the number of people who suffer from heat stroke and hypothermia at low cost.

  In the air conditioner of the embodiment, the notification means / method is based on lighting or blinking of an indicator lamp, character display, buzzer sounding or vibration, notification by voice, or a combination of these means / methods. is there.

  This makes it possible to use one of the transmission functions normally provided in an air conditioner, change the control software, and add low-cost, heat stroke and hypothermia without adding new parts. Can send prevention.

  For this reason, it is possible to provide an air conditioner that can notify the prevention of heat stroke and hypothermia and reduce the number of people who suffer from heat stroke and hypothermia at low cost.

  Moreover, the air conditioner of embodiment includes the image information obtained by the said imaging means in the information transmitted to the alerting | reporting terminal installed in the said other room, an external personal computer, or a mobile telephone.

  As a result, in addition to the standard text information, voice information, or mechanical indicator lights and buzzers, indoor image information can be received externally. Yes, it helps to take appropriate measures quickly, so you can leave the room with peace of mind, even if you leave the room to work in another room.

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

  Further, the air conditioner of the embodiment can select setting / cancellation of the function of informing or / and starting the operation of the air conditioner.

  As a result, in the season when there is a risk of heat stroke or hypothermia, a function to send a temperature and humidity alarm can be used to prevent heat stroke and hypothermia, and there is no risk of heat stroke or hypothermia. If you are away for a long time, such as when traveling, disable the function to send the temperature and humidity alarm, stop measuring the room temperature and humidity while the air conditioner is stopped, and operate the blower with ultra-fine wind prior to measurement. The energy required can be saved.

  Therefore, it is possible to provide an air conditioner capable of reducing the number of people suffering from heat stroke and hypothermia by notifying excessive heat consumption and reporting prevention of heat stroke and hypothermia.

  In addition, the air conditioner of the embodiment has the above-mentioned function and a predetermined range in which the measured indoor temperature or / and humidity may fall into heat stroke or hypothermia even when there is no occupant. In this case, the notification function and / or the function of starting the operation of the air conditioner can be selected with the remote controller as in the case where the occupant is present.

  Accordingly, it is possible to prevent an occupant from entering the blind spot of the human body detecting means and actually operating, but erroneously judging that the air conditioner is absent and performing an inappropriate operation. In addition, when it is known that there is always a person in the room, the notification or / and the operation of the air conditioner can be started without waiting for detection of the human body by the human body detection means, so that the room can be quickly returned to a safe state. .

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

In addition, the air conditioner according to the embodiment is configured so that the function when the occupant is not present is notified of the function or / and the operation of the air conditioner is started by the manual operation or the user of the control device. When the on / off action by the timer that can change the on / off time cannot be added,
The number of times of the notification or / and driving with the interruption of the notification or / and driving,
You can increase or decrease with the remote control.

  As a result, there are no people in the room, but if there are pets etc., the pets can transmit to other rooms or outside the fear that they will suffer from heat stroke or hypothermia. You can leave it to work in another room or go out and leave. Further, by reducing the number of times of notification or / and driving, energy required for notification or / and driving can be saved.

  For this reason, while suppressing the consumption of excess energy, it is gentle for pets and the like, and it is possible to inform the prevention of heat stroke and hypothermia and reduce the incidence of heat stroke and hypothermia. Can be provided.

  In the air conditioner of the embodiment, when the function of informing or / and starting the operation of the air conditioner is set, when a predetermined number of days elapses from the most recent manual operation on the control device, the user sets a timer When a predetermined number of days have passed since the most recent on / off operation by a timer that can change the on / off time of the tub, or a temperature in a predetermined range that may cause heat stroke or hypothermia with the temperature or / and humidity measurement means Alternatively, the function is switched from setting to canceling when a predetermined number of days have passed since the most recent time when the humidity was measured.

  As a result, heat and humidity hypothermia can be prevented by using the function to send temperature and humidity alarms in the season when heat stroke and hypothermia are possible. When it is in the season when there is no fear of it, or when it has been absent for a long time due to travel etc., the function to send the temperature and humidity alarm will be canceled when the predetermined number of days have passed, and the blower will be operated with ultra-fine wind prior to measurement The energy required can be saved.

  When the remote control is manually operated or turned on / off by a timer, the user intends to operate the air conditioner, and the period of use of the air conditioner has not passed. When a predetermined number of days have passed since that time (in the embodiment, two weeks in which the transition of the season can be realized), the function of issuing the temperature / humidity alarm is canceled.

  The case where the remote control is manually operated is not limited to the air conditioner remote control, but the case where the air conditioner can be operated from a mobile information terminal such as a mobile phone / smartphone. This includes cases where the air conditioner is operated manually.

  This is because when the user no longer needs to operate the air conditioner, for example, for two weeks, the room is monitored to see if it is in the strict warning temperature and humidity range, and the room is in the strict warning temperature and humidity range. If it does not enter, the function to send the temperature / humidity alarm because the user has forgotten to turn off the function to send the temperature / humidity alarm because no operation was added to the air conditioner for the past two weeks. Is automatically canceled and energy is saved during air-conditioning operation to send a temperature / humidity alarm.

  In addition, if the room is in the strict warning temperature and humidity range, a temperature and humidity alarm will be sent, and the automatic cancellation of the function to send the temperature and humidity warning will be made for two weeks from this point, assuming that the season has not changed yet. In the meantime, we will continue to monitor the indoor temperature and humidity, wait for the indoor temperature and humidity to be completely outside the strict warning temperature and humidity range, and automatically cancel the function to send out the above temperature and humidity alarm. To save money.

  Therefore, it is possible to provide an air conditioner capable of reducing the number of people suffering from heat stroke and hypothermia by notifying excessive heat consumption and reporting prevention of heat stroke and hypothermia.

  In the air conditioner of the embodiment, when the measured indoor temperature or / and humidity is in the severe warning range of heat stroke or hypothermia, the measured indoor temperature or / and humidity is hot. The interval for measuring the temperature or / and humidity in the room is made longer than in the case where the temperature is not within the strict warning range of symptom or hypothermia.

  As a result, if you are in the strict warning range of heat stroke or hypothermia, measure the indoor temperature and humidity at short intervals to quickly catch the rapid deterioration of the indoor environment, for example, send a stronger message If the room temperature and humidity are outside the strict warning range for heat stroke or hypothermia, the room temperature and humidity can be set longer. It is possible to reduce the consumption of energy to measure temperature and humidity alarms.

  Therefore, it is possible to provide an air conditioner capable of reducing the number of people suffering from heat stroke and hypothermia by notifying excessive heat consumption and reporting prevention of heat stroke and hypothermia.

  In addition, the air conditioner according to the embodiment sets the position of the wind direction control device located on the outer wall of the air conditioner for a predetermined time before measuring the indoor temperature and / or humidity. Operate at a lower speed than at rated operation in the position when the harmony machine is stopped.

  Thereby, while maintaining the appearance of the air conditioner that has been shut down, the indoor fan is rotated at an extremely low speed such that almost no noise can be felt, and the indoor air is circulated around the indoor temperature and humidity detector, An indoor temperature / humidity detector can accurately detect the indoor temperature / humidity.

  At this time, the appearance of the air conditioner remains stopped and the air blowing noise can be made extremely small, so the occupants do not notice the temperature and humidity measurement, and the stopped air conditioner starts to move by itself. There is no fear of receiving the said nonsense call. In the embodiment, the predetermined time is set to 3 minutes so that the temperature of the indoor temperature / humidity detector becomes familiar with the indoor air circulating around and the temperature / humidity of the room can be accurately detected.

  For this reason, it is possible to provide an air conditioner that can avoid nonsense calls, inform the prevention of heat stroke and hypothermia, and reduce the number of people who suffer from heat stroke and hypothermia.

  Next, an air conditioner according to Embodiment 3 of the present invention will be described.

  In the third embodiment, an air conditioner that notifies and transmits a temperature / humidity alarm and uses the air conditioner function of the air conditioner to improve the indoor environment will be described with reference to FIGS. 19 and 20. . FIG. 19 is a middle part of a schematic control flowchart of the temperature and humidity alarm function of the air conditioner according to the third embodiment. FIG. 20 is the latter part of the schematic control flowchart of the temperature / humidity alarm function of the air conditioner according to the third embodiment.

  In the air conditioner of the second embodiment, when the temperature / humidity alarm is notified / transmitted, the position of the airflow direction control device located on the outer wall of the air conditioner is displayed so that the air conditioner can be seen as if it has been stopped At the position when the air conditioner is stopped, it is operated at a lower speed than during rated operation, and the blowing noise is also reduced. On the other hand, the air conditioner of Embodiment 3 performs the same operation as normal air blowing, cooling, dehumidification or heating when notifying / transmitting the temperature / humidity alarm to improve the deteriorated indoor temperature / humidity. Meanwhile, temperature / humidity alarms are reported and transmitted.

  Since the first stage of the control flow of the temperature / humidity alarm function of the air conditioner of the third embodiment is the same as the first stage of the control flow of the temperature / humidity alarm function of the second embodiment (FIG. 13), description thereof is omitted. In the middle control flow (FIG. 19), the middle (FIG. 14) control flow of the second embodiment and the 5-minute timer in step S47 are changed to the 6-minute timer in step S47 *, and the super-wind operation in step S52 is performed in step S52. Instead of the alarm operation of *, the symbol C is added between step S53 * and step S60 *, and the other parts are the same, so only the changed part will be described.

  Note that the step symbols of the third embodiment have the same contents, but the step symbols of the second embodiment are marked with an asterisk for easy comparison. In step S47 * in FIG. 19, the 6 minute timer is started and the temperature / humidity alarm interruption time of 2 minutes in the second embodiment is changed to 3 minutes. This is because in Embodiment 3, the air conditioner is actually operated to change the indoor temperature and humidity in a safe direction, and the refrigeration cycle is also intermittently accompanied by the intermittent temperature and humidity alarm. This is to secure the stop time necessary for securing the above.

  In step S52 * of FIG. 19, an instruction for alarm operation is issued, and the air conditioner is blown, cooled, dehumidified, or heated with the same strength as during normal operation. By doing so, the occupant is given a cool feeling by controlling the air flow in the room by blowing air, and / or the room temperature and humidity are improved in the direction of extracting from the warning range by the air conditioning (including dehumidification) operation.

  In this way, the temperature and humidity in the room are changed in a safe direction, and the air conditioner that should have stopped is suddenly operated to draw the attention of the occupants, blinking the indicator light, sounding the buzzer, etc. Thus, it is possible to emphasize and notify that the indoor temperature and humidity are within the strict warning range, and to inform the occupants that the indoor temperature and humidity are within the strict warning range.

  In this case, since the alarm operation and the alarm operation are alternately interrupted, the indoor temperature and humidity are repeatedly improved and deteriorated alternately, and this causes the occupants to feel uncomfortable or irritated. In addition, by feeling irritated, it can be felt that there is a need to improve the indoor temperature and humidity environment, which can lead to preventive action against heat stroke and hypothermia at an early stage.

  Further, in the third embodiment, the measurement of the indoor temperature / humidity performed every time the temperature / humidity alarm is notified / transmitted in the second embodiment is stopped, and only the measurement of the indoor temperature / humidity in step S26 in FIG. 13 is performed. In general, heat enters and exits through structures such as walls and floors, so if the temperature and humidity of the room enters a strict warning range while the air conditioner is stopped, the temperature of the walls and floors is also strict. The temperature is within or close to the range.

  When the air conditioner is operated in this state, the temperature and humidity in the room are drastically improved. However, because the heat capacity of structures such as walls and floors is large, the temperature does not change abruptly, and the room does not change rapidly. Even if the temperature and humidity are measured and a result that it is out of the strict warning range is obtained, if the operation of the air conditioner is stopped, the temperature and humidity in the room will deteriorate immediately due to heat transfer from the wall or floor.

  For this reason, in the air conditioner of the third embodiment, the measurement of temperature and humidity is stopped every time the temperature and humidity alarm is notified and transmitted, and only the measurement of the room temperature and humidity in step S26 in FIG. The subsequent stage of the control flow of the temperature / humidity alarm function is as shown in FIG.

  If the 3-minute timer has expired in step S60 * of FIG. 19, the process proceeds to step S62 * of FIG. 20, instructing the stop of the alarm operation performed so far, stopping the operation of the air conditioner, and step S63 *. The temperature / humidity alarm notification and transmission will stop. Next, in step S70 *, it is checked whether there is an occupant. If there is an occupant, the process proceeds to step S85 *, and it is checked whether 6 minutes have elapsed since the start of the 6-minute timer in step S47 *. To do.

  This is because the temperature and humidity in the room is in the strict warning temperature and humidity range, so that the temperature and humidity alarm is temporarily interrupted in order to repeat the temperature and humidity alarm, and in the embodiment, this interruption time is set to 3 minutes. A 5-minute timer was used to count 3 minutes from the time-up of the 3-minute timer.

  If there is no occupant in step S70 *, the process proceeds to step S80 * to check whether the temperature / humidity alarm is set to be notified / transmitted only for the first time even when there is no occupant. If the temperature / humidity alarm is set to be notified / transmitted only at the first time in step S80 *, the temperature / humidity alarm has already been notified / transmitted in step S53 * of FIG. No notification / transmission is performed, and the process returns to step S10 in FIG.

  If the temperature / humidity alarm is not set to be notified / transmitted only at the first time in step S80 *, even if there is no occupant, the temperature / humidity alarm is repeatedly notified when the room is in the strict warning temperature / humidity range. In order to make a transmission, the process proceeds to step S85 * and, as described above, enters an interruption time for repeatedly informing / transmitting a temperature / humidity alarm.

  If the 6-minute timer has not expired in step S85 *, the process returns to step S55 * via C to notify and send a repeated temperature / humidity alarm, and steps S55 *, S60 *, S62 *, S63 *, S70. *, S80 *, and S85 * are repeated, and the temperature / humidity alarm interruption time elapses.

  If the 6-minute timer has expired in step S85 *, the process proceeds to step S90 * to check whether the 30-minute timer has expired. While the 30-minute timer does not time out in step S90 *, the process returns to step S47 * in FIG. 19 via B, and the temperature / humidity alarm notification and transmission for 3 minutes and interruption for 3 minutes are repeated alternately. Or / and repeatedly externally notify / transmit temperature / humidity alarm.

  In this way, I received a temperature / humidity alarm, but even if I forget to deal with it because of other things, I will remember that I will deal with it again by receiving another temperature / humidity alarm. The temperature and humidity in the room can be changed from the strict warning range to the safe side by operating the machine.

  When the 30-minute timer has expired in step S90 *, 30 minutes have passed since the activation of the 30-minute timer in step S46 * of FIG. Since there is no response such as when there is no occupant, the process returns to step S10 in FIG. 13 via E to continue monitoring the room temperature and humidity.

  In this way, even if it is determined that there is no occupant once, while the temperature and humidity in the room continue to be within the warning range for heat stroke, the temperature and humidity alarm every 6 minutes is sandwiched between 20 minutes of operation monitoring. Repeated 30 minutes of notification / transmission and interruption, even if the temperature / humidity alarm notification / transmission is overlooked, the temperature / humidity alarm will be issued steadily until it is out of the warning range of heat stroke. Therefore, appropriate measures to prevent heat stroke can be taken.

  Moreover, even if the occupant is not aware of the temperature / humidity alarm, ignores it, or cannot perform the driving operation, the indoor temperature / humidity can be improved in a safe direction from the warning range. In particular, when temperature / humidity alarms are communicated to other rooms or to the outside, the temperature / humidity in the room is safe from the warning range, if not enough, while the person who notices the temperature / humidity alarms rushes. Therefore, the adverse effects of heat stroke and hypothermia can be reduced.

  Thus, in the air conditioner of the embodiment, the transmission is performed after the start of the air conditioning operation.

  As a result, if there is an occupant and the temperature or / and humidity in the room are within a predetermined range where the occupant may suffer from heat stroke or hypothermia, the air conditioner is operated anyway. To change the temperature and humidity changes in the room in a safe direction. Thereafter, the information is transmitted to the notification terminal in the room or / and the notification terminal installed in the other room, the external personal computer or the mobile phone.

  Therefore, it is possible to provide an air conditioner that can quickly improve indoor temperature and humidity, notify the prevention of heat stroke and hypothermia, and reduce the number of people suffering from heat stroke and hypothermia. .

  In addition, the air conditioner of the embodiment performs air blowing, dehumidification, cooling, or heating operation for a predetermined time before measuring the indoor temperature or / and humidity.

  As a result, in addition to the notification and transmission of temperature / humidity alarms by display, buzzer, sound, video, etc., the air conditioner is actually operated to improve the deteriorated indoor temperature / humidity environment, while the wind / cooling air / heating air However, it is possible to inform people in the room that the temperature and humidity range is strictly warranted, and to inform people who are blind or deaf to the risk of heat stroke or hypothermia. At this time, it is natural to automatically select cooling in the cooling season and heating in the heating season.

  For this reason, the air conditioner which can alert | report prevention of heat stroke and hypothermia, and can reduce reliably the person who falls into heat stroke and hypothermia can be provided.

  As described above, according to the air conditioner of the first aspect, the human body detecting means and the temperature or / and humidity measuring means are provided, and the human body is detected and measured while the air conditioning operation is stopped. If the room temperature or / and humidity is within a predetermined range where the occupants may suffer from heat stroke or hypothermia, this is notified, and / or the air conditioning machine is started. .

  As a result, even when the air conditioner is intentionally stopped by the user or controlled, the air conditioner is turned off when the room temperature is 30 ° C. and the humidity exceeds 65%, for example, at the cooling time. Inform the user of a message (temperature / humidity alarm) recommending driving. The notification means and method may be any means such as display, buzzer, sound, and video. In addition, it may be possible to transmit to a housemate in another room by transmission line or wirelessly, and further, a mobile phone terminal of a family member who is out or an outside welfare person via a wireless communication network such as the Internet. It may be sent to the

  Also, the room temperature and humidity levels for notification are not limited to the above one point. For example, the lower boundary points shown in FIG. 12, such as 25 ° C. 100%, 35 ° C. 35%, etc. May be stored, and the notification operation may be started when the room temperature humidity is higher than the line connecting these points.

  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 It is possible to prevent heat stroke by welfare personnel such as starting air conditioners.

  In the heating season, the body temperature can be adjusted by the amount of clothing, so the control is more complicated than when preventing heat stroke.For example, the amount of clothing is estimated according to the outside air temperature, In combination with the amount of activity, the recommended heating temperature is automatically set, the range where the room temperature is lower than the predetermined value is set as a strict warning range, and when the room temperature falls to this range, the driving recommendation notification is performed. Also good.

  In addition, the air conditioner may be operated instead of or in addition to the notification. In this case, the temperature and humidity in the room changes in a safer direction, and the occupant is in the heat stroke or hypothermia. The risk of falling into

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

  According to the air conditioner of the second aspect, the remote controller of the air conditioner has the function of changing the predetermined range.

  Thus, for example, if the difference between the temperature and humidity detected by the air conditioner in normal cooling and heating operation and the temperature and humidity around the occupant is large, the predetermined range is set to the high temperature and high humidity side. If the difference is felt that the difference is small, the predetermined range is changed to the low temperature and low humidity side.

  As a result, when the temperature of the occupant reaches a temperature range that may cause heat stroke or hypothermia more appropriately, the temperature around the occupant is more appropriately determined. And by starting the operation of the air conditioner, it is possible to prevent the occupants from falling into heat stroke or hypothermia.

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

  According to the air conditioner of the third aspect, the human body is detected based on the image information from the imaging means.

  As a result, human body detection is performed based on image information from the imaging means, so that the human body can be reliably detected even in situations where the room temperature, wall and floor temperatures are close to body temperature, and people in the room are susceptible to heat stroke. Then, this is notified or / and the operation of the air conditioner is started. Thereby, even in the summer when heatstroke frequently occurs, it is possible to accurately detect the human body and prevent the occupants from suffering from heatstroke.

  In winter, human body detection is not hindered by warm air or heat radiation from the heater, so the accuracy of human body detection will not be reduced, and reliable detection of human bodies throughout the year will notify dangerous conditions. By starting the operation of the air conditioner, it is possible to prevent in advance the risk of falling into heat stroke or hypothermia.

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

  Further, according to the air conditioner of claim 4, the timer that allows the manual operation to the control device or the user to change the on / off time of the timer even after the notification or / and the operation of the air conditioner is started. When the on / off operation by is not added, the notification or / and operation is repeated a plurality of times with interruption of the notification or / and operation.

  As a result, if no operation is performed after the temperature / humidity alarm is issued despite being in the strict warning range of heat stroke or hypothermia, the occupants may not be aware of the temperature / humidity alarm. Because it is strong, it repeats the temperature and humidity alarm as well as the snooze function of the alarm clock (in the example, when the compressor is operated, it is transmitted every 6 minutes, and when the compressor is not operated, it is transmitted every 5 minutes) In order to stop the temperature and humidity alarm, some operation must be performed on the air conditioner, which inevitably takes action to avoid heat stroke or hypothermia, thereby preventing heat stroke or hypothermia. it can.

  For this reason, the air conditioner which can alert | report prevention of heat stroke and hypothermia and can surely reduce the person who falls into heat stroke and hypothermia can be obtained.

  According to the air conditioner of claim 5, the information is transmitted from the indoor unit or / and the remote controller of the air conditioner or / and from the indoor unit or / and the remote controller of the air conditioner. Based on an information terminal installed in another room, an external mobile phone, a mobile information terminal such as a smartphone, or a personal computer.

  As a result, the transmission function normally provided in the air conditioner (lighting or blinking of the indicator lamp, ringing of the buzzer, notification by voice (including synthesized voice), transmission to other rooms via transmission line, to other places via the Internet Can be used to send heat prevention and hypothermia prevention information at low cost without changing the control software. it can.

  For this reason, it is possible to obtain an air conditioner that can notify the prevention of heat stroke and hypothermia and reduce the number of people who suffer from heat stroke and hypothermia at low cost.

  Moreover, according to the air conditioner of Claim 6, the said transmission is performed after the start of the said air conditioning operation | movement.

  As a result, if there is an occupant and the temperature or / and humidity in the room are within a predetermined range where the occupant may suffer from heat stroke or hypothermia, the air conditioner is operated anyway. To change the temperature and humidity changes in the room in a safe direction. Thereafter, the information is transmitted to the notification terminal in the room or / and the notification terminal installed in the other room, the external personal computer or the mobile phone.

  Therefore, it is possible to obtain an air conditioner that can quickly improve indoor temperature and humidity, notify the prevention of heat stroke and hypothermia, and reduce the number of people who suffer from heat stroke and hypothermia.

  Further, according to the air conditioner according to claim 7, the notification means / method includes lighting or blinking of an indicator lamp, character display, sounding or vibration of a buzzer, notification by voice, or a combination of these means / methods. Is due to.

  This makes it possible to use one of the transmission functions normally provided in an air conditioner, change the control software, and add low-cost, heat stroke and hypothermia without adding new parts. Can send prevention.

  For this reason, it is possible to obtain an air conditioner that can notify the prevention of heat stroke and hypothermia and reduce the number of people who suffer from heat stroke and hypothermia at low cost.

  According to the air conditioner described in claim 8, the image information obtained by the imaging means is included in the information transmitted to the notification terminal, the external personal computer or the mobile phone installed in the other room.

  As a result, in addition to the standard text information, voice information, or mechanical indicator lights and buzzers, indoor image information can be received externally. Yes, it helps to take appropriate measures quickly, so you can leave the room with peace of mind, even if you leave the room to work in another room.

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

  In addition, according to the air conditioner of the ninth aspect, it is possible to select setting / cancellation of the function of informing or / and starting the operation of the air conditioner.

  As a result, in the season when there is a risk of heat stroke or hypothermia, a function to send a temperature and humidity alarm can be used to prevent heat stroke and hypothermia, and there is no risk of heat stroke or hypothermia. If you are away for a long time, such as when traveling, disable the function to send the temperature and humidity alarm, stop measuring the room temperature and humidity while the air conditioner is stopped, and operate the blower with ultra-fine wind prior to measurement. The energy required can be saved.

  For this reason, it is possible to obtain an air conditioner that can prevent the heat stroke and hypothermia and reduce the number of people who suffer from heat stroke and hypothermia while suppressing excessive energy consumption.

  In addition, according to the air conditioner of claim 10, the measured indoor temperature or / and humidity may fall into heat stroke or hypothermia even when there is no occupant in the room. When it is in the predetermined range, the function of informing or / and starting the operation of the air conditioner can be selected with the remote controller as in the case where the occupant is present.

  Accordingly, it is possible to prevent an occupant from entering the blind spot of the human body detecting means and actually operating, but erroneously judging that the air conditioner is absent and performing an inappropriate operation. In addition, when it is known that there is always a person in the room, the notification or / and the operation of the air conditioner can be started without waiting for detection of the human body by the human body detection means, so that the room can be quickly returned to a safe state. .

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

In addition, according to the air conditioner according to claim 11, a manual operation or a user operation on the control device even after the notification of the function when the occupant is not present and / or the operation of the air conditioner is started. If the timer on / off operation cannot be added by the timer that can change the timer on / off time,
The number of times of the notification or / and driving with the interruption of the notification or / and driving,
You can increase or decrease with the remote control.

  As a result, there are no people in the room, but if there are pets etc., the pets can transmit to other rooms or outside the fear that they will suffer from heat stroke or hypothermia. You can leave it to work in another room or go out and leave. Further, by reducing the number of times of notification or / and driving, energy required for notification or / and driving can be saved.

  For this reason, while suppressing the consumption of excess energy, it is gentle for pets and the like, and it is possible to inform the prevention of heat stroke and hypothermia and reduce the incidence of heat stroke and hypothermia. Can be obtained.

  Further, according to the air conditioner according to claim 12, when the function of informing or / and starting the operation of the air conditioner is set, the time when a predetermined number of days have passed since the most recent manual operation on the control device is used. When a predetermined number of days have elapsed since the most recent on / off operation by a timer that allows the person to change the on / off time of the timer, or the temperature or / and humidity measurement means may cause heat stroke or hypothermia The function switches from setting to canceling when a predetermined number of days have passed since the most recent measurement of temperature or / and humidity in the range.

  As a result, heat and humidity hypothermia can be prevented by using the function to send temperature and humidity alarms in the season when heat stroke and hypothermia are possible. When it is in the season when there is no fear of it, or when it has been absent for a long time due to travel etc., the function to send the temperature and humidity alarm will be canceled when the predetermined number of days have passed, and the blower will be operated with ultra-fine wind prior to measurement The energy required can be saved.

  When the remote control is manually operated or turned on / off by a timer, the user intends to operate the air conditioner, and the period of use of the air conditioner has not passed. When a predetermined number of days have passed since that time (in the embodiment, two weeks in which the transition of the season can be realized), the function of issuing the temperature / humidity alarm is canceled.

  The case where the remote control is manually operated is not limited to the air conditioner remote control, but the case where the air conditioner can be operated from a mobile information terminal such as a mobile phone / smartphone. This includes cases where the air conditioner is operated manually.

  This is because when the user no longer needs to operate the air conditioner, for example, for two weeks, the room is monitored to see if it is in the strict warning temperature and humidity range, and the room is in the strict warning temperature and humidity range. If it does not enter, the function to send the temperature / humidity alarm because the user has forgotten to turn off the function to send the temperature / humidity alarm because no operation was added to the air conditioner for the past two weeks. Is automatically canceled and energy is saved during air-conditioning operation to send a temperature / humidity alarm.

  In addition, if the room is in the strict warning temperature and humidity range, a temperature and humidity alarm will be sent, and the automatic cancellation of the function to send the temperature and humidity warning will be made for two weeks from this point, assuming that the season has not changed yet. In the meantime, we will continue to monitor the indoor temperature and humidity, wait for the indoor temperature and humidity to be completely outside the strict warning temperature and humidity range, and automatically cancel the function to send out the above temperature and humidity alarm. To save money.

  For this reason, it is possible to obtain an air conditioner that can prevent the heat stroke and hypothermia and reduce the number of people who suffer from heat stroke and hypothermia while suppressing excessive energy consumption.

  Further, according to the air conditioner according to claim 13, when the measured indoor temperature or / and humidity is within a severe warning range of heat stroke or hypothermia, the measured indoor temperature or / and The interval for measuring the room temperature and / or humidity is set longer than when the humidity is not within the strict warning range of heat stroke or hypothermia.

  As a result, if you are in the strict warning range of heat stroke or hypothermia, measure the indoor temperature and humidity at short intervals to quickly catch the rapid deterioration of the indoor environment, for example, send a stronger message If the room temperature and humidity are outside the strict warning range for heat stroke or hypothermia, the room temperature and humidity can be set longer. It is possible to reduce the consumption of energy to measure temperature and humidity alarms.

  For this reason, it is possible to obtain an air conditioner that can prevent the heat stroke and hypothermia and reduce the number of people who suffer from heat stroke and hypothermia while suppressing excessive energy consumption.

  According to the air conditioner of claim 14, prior to measuring the temperature or / and humidity in the room, the air blower of the wind direction control device located on the outer wall of the air conditioner for a predetermined time is measured. Set the position to the position when the air conditioner is stopped and operate at a lower speed than during rated operation.

  Thereby, while maintaining the appearance of the air conditioner that has been shut down, the indoor fan is rotated at an extremely low speed such that almost no noise can be felt, and the indoor air is circulated around the indoor temperature and humidity detector, An indoor temperature / humidity detector can accurately detect the indoor temperature / humidity.

  At this time, the appearance of the air conditioner remains stopped and the air blowing noise can be made extremely small, so the occupants do not notice the temperature and humidity measurement, and the stopped air conditioner starts to move by itself. There is no fear of receiving the said nonsense call. In the embodiment, the predetermined time is set to 3 minutes so that the temperature of the indoor temperature / humidity detector becomes familiar with the indoor air circulating around and the temperature / humidity of the room can be accurately detected.

  For this reason, it is possible to obtain an air conditioner that can avoid nonsense calls, notify the prevention of heat stroke and hypothermia, and reduce the number of people who fall into heat stroke and hypothermia.

  According to the air conditioner of the fifteenth aspect, prior to measuring the indoor temperature or / and humidity, the air conditioner is operated for blowing, dehumidifying, cooling or heating for a predetermined time.

  As a result, in addition to the notification and transmission of temperature / humidity alarms by display, buzzer, sound, video, etc., the air conditioner is actually operated to improve the deteriorated indoor temperature / humidity environment, while the wind / cooling air / heating air However, it is possible to inform people in the room that the temperature and humidity range is strictly warranted, and to inform people who are blind or deaf to the risk of heat stroke or hypothermia. At this time, it is natural to automatically select cooling in the cooling season and heating in the heating season.

  For this reason, the air conditioner which can alert | report prevention of heat stroke and hypothermia and can surely reduce the person who falls into heat stroke and hypothermia can be obtained.
