It is a top view which shows the wind flow in. In addition, each figure is drawn typically and this invention is not limited to the form shown in figure.

1 to 3, an air conditioner indoor unit (hereinafter referred to as “indoor unit”) 100 opens and closes a main body 1 having a suction port 3 formed in an upper portion and a blower outlet 7 formed in a lower portion, and the front surface of the main body 1. The front panel 2 that covers freely, the blower 5 that sucks room air from the suction port 3 and forms the air passage 6 leading to the blower outlet 7, and the heat exchange installed on the upstream side of the blower 5 (near the suction port 3) And 4.
A receiving device 40 that receives a signal from a remote controller (not shown) and an imaging device 50 that captures an indoor situation are installed on the front surface of the main body 1 beside the air outlet 7.
Note that the present invention does not limit the type or installation position of the receiving device 40 or the imaging device 50, and may be installed at the center of the front panel 2, for example. Furthermore, a voice or video notification device (not shown) for notifying the operation status of the indoor unit is provided in the main body 1 or a remote controller (not shown).

  The heat exchanger 4 is a portion 4a before heat exchange that is a portion substantially parallel to the front panel 2, a front portion 4b that is an upper portion of the fan 5 that is obliquely above the front surface, and a portion that is obliquely above the rear surface of the fan 5. And a rear portion 4c for heat exchange. A drain pan 8 is disposed below the pre-heat exchange portion 4a, and the upper surface 8a of the drain pan 8 forms a drain pan surface that actually receives the drain, and the lower surface 8b of the drain pan 8 forms the front side of the air passage 6. Yes.

(Wind direction adjusting device)
At the position near the air outlet 7 of the air passage, the horizontal direction (left and right direction) blowing direction of the indoor air conditioned in the heat exchanger 4 (hereinafter referred to as “conditioned air”), which is a wind direction adjusting device, is adjusted. Left and right wind direction plate group 10L and right and left and right wind direction plate group 10R (collectively or respectively referred to as “left and right wind direction plate 10”) and the air outlet 7 which is the end of the air path 6 are provided with conditioned air. A vertical wind direction plate 9 (the front vertical wind direction plate 9a and the rear vertical wind direction plate 9b are collectively referred to as the "vertical wind direction plate 9") is provided for adjusting the blowing direction in the vertical direction (vertical direction).
Note that the “left side” and “right side” refer to what is seen on the left hand when viewing the room from the indoor unit 100, that is, when viewing the front panel 2 from the back side of the main body 1. The ones that are visible on the right hand are referred to as the “right side”.

(Left and right wind direction plate)
The right and left wind direction plate group 10R is composed of left and right wind direction plates 10a, 10b,..., 10g, is rotatably installed on the lower surface 8b of the drain pan 8, and the right connecting rod 20R is connected to each. The left and right wind direction plate group 10L is composed of left and right wind direction plates 10h, 10i,..., 10n, and a left connecting rod 20L is connected to each.
The right and left wind direction plate group 10R and the right connecting rod 20R form a link mechanism, and the left and right wind direction plate group 10L and the left connecting rod 20L form a link mechanism, and the right connecting rod 20R has a right drive. The left driving means 30L is connected to the left connecting rod 20L.
Therefore, when the right connecting rod 20R is translated by the right driving means, the left and right wind direction plates 10a, 10b,... 10g rotate while maintaining parallel to each other, and the left connecting rod 20L is translated by the left driving means 30L. When done, the left and right wind direction plates 10h, 10i,..., 10n rotate while maintaining parallel to each other. For this reason, conditioned air is blown out in the same direction over the entire width of the blowout port 7, blown out in a direction away from each other at every half width of the blowout port 7, or blown out in a direction to collide with each other at every half width of the blowout port 7. Is possible.
The present invention is not limited to the shape of the left and right wind direction plates 10 illustrated. The number of the left and right wind direction plates 10 may be any number, and the left and right wind direction plates 10 are divided into three or more groups. The group may be joined to the connecting rod so as to be rotatable, and each connecting rod may be independently translated.

(Vertical wind direction plate)
The vertical wind direction plate 9 has a rotation center parallel to the horizontal direction (Y direction), and is rotatably installed on the main body 1. The rotation axis of the front vertical wind direction plate 9a and the rotation axis of the rear vertical wind direction plate 9b are respectively connected by a link mechanism or a gear mechanism and rotated by a common drive motor.
In addition, this invention is not limited to what shows the form of the up-and-down wind direction board 9, The front up-and-down wind direction board 9a and the back up-and-down wind direction board 9b may each be rotated by a separate drive motor. Also, each of them may be divided at the center in the left-right direction to make a total of four sheets, and each may be independently rotated.

(Control device)
The indoor unit 100 is provided with a control device (not shown). The control device controls the temperature of the conditioned air, the amount of blowout, and the like (hereinafter referred to as “wind direction control”) in accordance with the indoor environment and user (resident) requirements.
The indoor unit 100 identifies a position (or destination) where a user who is hot or cold is present and blows conditioned air toward the identified position, so first (for example, immediately after entering the room) ), The user needs to make the control means recognize that he / she is “hot or cold”, and therefore, the user needs to approach the indoor unit 100 and recognize his / her face.

Then, the control device identifies the location of the user by tracking the movement of the user, assuming that the user who has approached the indoor unit 100 and recognized his / her face is “Mr. Therefore, the postures of the left and right wind direction plates 10 and the upper and lower wind direction plates 9 are controlled so that the conditioned air is concentrated locally (spot-like) toward the specified location (hereinafter referred to as “concentrated blowing”). (Hereafter referred to as “wind direction centralized control”).
On the other hand, when there is no user who is hot or cold (when there is no user who has approached the indoor unit 100 and recognized his / her face), the conditioned air is directed to the room approximately average or preset. The postures of the left and right wind direction plates 10 and the vertical wind direction plate 9 are controlled (hereinafter, referred to as “distributed blowing”) (hereinafter, referred to as “distributed blowing”). This is called “wind direction dispersion control”).

(User face recognition)
FIG. 4 is a diagram for explaining a user's face recognition procedure, in which the indoor unit 100 is located near one of the walls 91 (hereinafter referred to as a “back wall”) 91 near the ceiling surface 92. is set up.
In addition, the imaging apparatus (for example, a 300,000 pixel CCD camera) 50 has a field of view 51 that faces obliquely downward. In the field of view 51, the face F1 of the user U1 is within a range 52 (shown by hatching in the drawing, referred to as “face recognition range”) within the distance L1 to the distance L2 (> L1) from the imaging device 50. At some point, the control device recognizes the face F1.

Further, when the user U1 is closer than the distance L3 (> L2) from the imaging device 50, the control device “the user U1 makes the indoor unit 100 recognize that he is hot or cold. If the face F1 is not within the face recognition range 52 while approaching the distance L3, a notification means (not shown) is notified.
For example, a voice notification such as “Cannot recognize face” or “Please move closer” is used, or a lamp indicating that the face cannot be recognized is lit or blinked. Note that the notification means may display characters or images instead of the sound or lighting or blinking of the lamp.

On the other hand, when the user F1 does not recognize the face F1 until the predetermined time (for example, 10 seconds) elapses while approaching the distance L3 (> L2) from the imaging device 50 (the face F1 is within the face recognition range 52). "When the user U1 is not trying to make the indoor unit 100 recognize that he is hot or cold" or "User U1 is not hot or cold", That is, it is determined that there is no need to perform wind direction concentration control.
At this time, a notification means (not shown) may notify the fact. For example, a notification such as “I will drive in normal mode” is given by voice, or a lamp indicating “Driving in normal mode” is lit or blinked.

(User tracking)
After recognizing the face F1 of the user U1, the control device tracks the user U1 from the appearance of the user U1 captured by the imaging device 50, and specifies the destination (hereinafter referred to as “user position”) P1. . Then, the conditioned air is locally concentrated and blown toward the identified user position P1 (concentrated blow).
Immediately after recognizing the face F1, the user U1 is moving away from the indoor unit 100. Therefore, after the movement is finished, that is, the position where the user U1 stops or the position where the user U1 is sitting Specify as P1.

(Wind direction control)
The wind direction control executed by the control device will be described based on the flowcharts shown in FIGS. 5 and 6 and the plan views shown in FIGS. 7 and 8.
5 and 6, when the face F1 of the user U1 is in the face recognition range 52 (S1), the control device recognizes the face F1 (S2). Then, it is determined whether the refrigeration cycle is operating (cooling operation, heating operation, etc.) or stopped (S3). If it is stopped, the refrigeration cycle is started (S4).

Further, the movement of the user U1 is tracked (S5), and the position where the user U1 stops or the user position P1 where the user U1 is sitting is specified (S6). And the attitude | position of the left-right wind direction board 10 and the up-and-down wind direction board 9 is controlled so that the conditioned air locally concentrated toward the user position P1 is sent (concentrated blowing) (S7).
As described above, since the concentrated blowing toward the user position P1 is started, if the hot person (or the cold person) other than the user U1 who is the hot person (or the cold person) is also in the user position P1, the conditioned air Can be received intensively. Note that the user U1 who is hot (or cold) receives conditioned air at a position different from the user position P2 where the user U2 who is not hot (or cold) is present.

(Concentrated blowing)
In FIG. 7A, when the user position P1 is on the left side of the room 90 (left hand as viewed from the indoor unit 100), both the right and left wind direction plate group 10R and the left and right wind direction plate group 10L (see FIG. 3) The posture is such that the conditioned air is blown out toward the user position P1 (concentrated blowing posture). Therefore, the user U1 receives the conditioned air for a longer time or in a larger amount than the case where the conditioned air is blown out almost uniformly into the room 90 (distributed blowing).
That is, when the user U1 who is hot (or cold) enters the room 90 from the outside where the temperature is high (or low), he searches the remote control and presses the cooling (or heating) start button installed on the remote control. The cooling operation (or heating) can be started only by bringing the face F1 closer to the indoor unit 100. Moreover, if the user moves and stops or sits at a predetermined position, the position is automatically specified as the user position P1, and cold air (or warm air) is sent toward the user position P1, so There is no need to operate a remote control or the like so that conditioned air can be reliably delivered.
Therefore, convenience and comfort are improved. That is, a local “cool feeling (cool) mode” is realized for Mr. Hot, and a local “warm (hot) mode” is realized for Mr. Cold.

The air flow of the conditioned air that has been blown out can be regarded as a bundle of substantially uniform flow speeds having substantially the same cross section as the size of the blowout outlet immediately after being blown out, but may be mixed with the surrounding air while flowing through the room 90. However, the air flow when it actually reaches the user position P1 has a large cross section compared to the size of the air outlet, and even in the cross section, the flow direction and the flow velocity are various air flows. It is a set of bundles.
Therefore, in the present invention, “locally concentrated” and “concentrated blowout” mean that the center when the spread air flow is averaged is “toward a specific position”, and the user position It means that conditioned air has also reached around P1.
In the above, both the right and left wind direction plate group 10R and the left and right wind direction plate group 10L blow conditioned air toward the user position P1, but the present invention does not limit the point of concentrated blowing to this. Absent.

For example, as shown in FIG. 7B, the left and right wind direction plate group 10L is always fixed in a posture in which conditioned air blows out toward the user position P1, and the right and left wind direction plate group 10R includes the user position P1 and the user position. You may rotate (swing) so that conditioned air may be blown out while reciprocating within a predetermined range (indicated by α in the figure) including P2.
Then, since a larger amount of conditioned air is intensively blown toward the user U1 who is hot (or cold), the comfort of the user U1 is enhanced and the range excluding the user position P1 is not included. A smaller amount of conditioned air will be blown out intermittently.
For this reason, when the user U2 who is different in temperature from the user U1 and who is not hot (or cold) is in the user position P2 which is different from the user position P1, the user position P2 is more Since a small amount of conditioned air is blown intermittently, the comfort of the user U2 is also maintained.

Further, as shown in FIG. 7C, both the right and left wind direction plate group 10R and the left and right wind direction plate group 10L are in a predetermined range including the user position P1 and the user position P2 (indicated by α in the figure). ) Is rotated (swinged) to blow out conditioned air, and in the range (indicated by β in the figure) toward the user position P1, the swing speed is slower (the blowing time is longer) than the range excluding this. ). Then, similarly to the case shown in FIG. 7B, the comfort of the user U2 who is not hot (or Mr. cold) is maintained together with the user U1 who is hot (or cold). .
In addition, the selection of the point of concentrated blowing (selection shown in either (a), (b) or (c) of FIG. 7) may be determined in advance, or it may be hot (or cold) The user U1 may be determined or changed by a remote controller or the like when the concentrated blowing is started or after it is started.

In FIG. 6, when the user U1 or another user operates a remote control device (remote controller) (not shown) and presses a button for stopping the concentrated blowing while executing the concentrated blowing (S8 described in FIG. 5). The control device stops the concentrated blowing and starts the distributed blowing (S10). That is, the dispersion blowing is started without concentrating on the user position P1 and blowing the conditioned air.
On the other hand, when the button for stopping the concentrated blowing is not pressed during the concentrated blowing (S8), the control device continues to track the position of the user U1 where the face F1 is recognized.

  When it is determined that the user U1 has been at the user position P1 for a predetermined time (for example, 30 minutes) without moving (S11), the concentrated blowing is stopped and the distributed blowing is started (S10). ). In other words, the user U1 who is hot (cold) is cooled (heated) by the concentrated air blow during such a predetermined time, and can feel sufficient comfort even if switching to normal cooling (heating). Estimated.

On the other hand, when it is determined that the user U1 has moved before a predetermined time (for example, 30 minutes) has passed (S11), it is further determined whether the user U1 is in the room 90 or has gone out of the room (S12). ).
When it is determined that the user U1 is in the room 90, the user position P3 that is the destination of the user U1 is specified (S13). Therefore, when it is determined that there is no other user in the room 90 (S14), instead of the concentrated blowing toward the user position P1, concentrated blowing toward the user position P3 is started (S15, FIG. 8). (See (a)).
On the other hand, when it is determined that there is another user, the user position P2 where the other user U2 (not hot (san) is not) is located is specified, and the user position P3 and the user position where the user U1 is moved It is determined whether P2 matches or is different (S16).
In S16, when it is determined that the user U1 has moved to the user position P2 (the user position P3 and the user position P2 match), the concentrated blowing is stopped and the distributed blowing is started (S10, FIG. 8). (See (b)). That is, the comfort of other users U2 is not disturbed.
On the other hand, when it is determined that the user U1 has moved to a position other than the user position P2 (the user position P3 and the user position P2 are different), the user U1 is the destination instead of the concentrated blowing toward the user position P1. Concentrated blowing toward the user position P3 is started (S15, see FIG. 8B).

  After determining that the user U1 has gone out of the room 90 in S12, if the user presses the button to stop the concentrated blowing (S17), as long as there is a user in the room 90 (S9), the concentrated blowing is stopped and distributed. Blowout is started (S10). On the other hand, when a predetermined time (for example, 10 minutes) elapses after the user U1 goes out of the room 90 (S18), as long as there is a user in the room 90 (S9), the concentrated blowing is stopped and the distributed blowing is performed. Start (S10, see FIG. 8C). That is, once the user U1 exits the room 90, regardless of whether the user U1 comes back again or not, as long as someone (user) is in the room 90, the concentrated blowing is started for a predetermined time (time ) Has passed, it switches to distributed blowing.

If it is determined in S9 that there is no one in the room (no user), the refrigeration cycle is stopped (S20). If it is determined in S9 that there is a user in the room, the concentrated blowing is stopped and the distributed blowing is started (S10).
Further, when someone (user) operates a remote control device (remote controller) (not shown) and presses a button (stop button for cooling or heating) during the dispersed blowing (S19), The cycle operation is stopped (S20).

[Embodiment 2]
FIG. 9 is a flowchart illustrating an indoor unit of an air conditioner according to Embodiment 2 of the present invention. In addition, the same code | symbol is attached | subjected to the same site | part or the same step as Embodiment 1, and one part description is abbreviate | omitted.
The indoor unit (hereinafter referred to as “indoor unit”) 200 of the air conditioner according to Embodiment 2 wants to cool quickly and rapidly immediately after entering the room from the outside of a bath or hot (or cold). It responds to the request of a user who wants to warm up (hereinafter referred to as “Yamago-san”).

That is, the indoor unit 100 according to the first embodiment tracks the movement of the user U1 whose face has been recognized and performs concentrated blowing toward the user position P1 that is the movement destination (see S7 in FIG. 5). When the user U1 continues to stay at the user position P1 as the destination for a predetermined time (for example, 30 minutes), when the predetermined time (for example, 30 minutes) has elapsed, the concentrated blowing is stopped and distributed. The blowout is started (see S10 and S11 in FIG. 6).
Then, in the indoor unit 100 according to the first embodiment, Mr. Yugori starts the indoor unit 100 by recognizing the face immediately after the bathing, and the closest position P0 of the indoor unit 100 (the user U1 recognizes the face F1 as the face recognition range 52). And a relatively narrow range including the range (see FIG. 7), and after a predetermined time (for example, 10 minutes), the vehicle is away from the close position P0. Concentrated blowing will continue toward the moving hot water. At this time, Mr. Yumae does not want concentrated blowing and sometimes desires distributed blowing, so the indoor unit 200 of Embodiment 2 supports this.

In FIG. 9, the indoor unit 200 starts concentrated blowing toward the user position P1 standing at the closest position P0 (S7), and when the concentrated blowing continues (S8), the user U1 It is determined whether or not the user stays at the closest position P0 (continues to stand) even if the closest determination time (for example, 30 seconds) elapses (S21).
That is, when the user U1 is “Mr. Yutaka”, the concentrated blowing is executed toward the closest position P0 (at this time, the user position P1 coincides with the close position P0), and thus the user U1 is in the closest position P0. Can cool down (S22). Then, the concentrated blowing is continued during the closest blowing time (for example, 10 minutes) that is a predetermined time until the cooling is finished (S22), and when the closest blowing time (for example, 10 minutes) has elapsed, the distributed blowing is performed. (See S9 and S10 in FIG. 6).
In addition, when the user U1 finishes cooling and leaves the close position P0 before the close blowing time (for example, 10 minutes) elapses (S23), the process shifts to distributed blowing when the user U1 leaves (see FIG. 6). Of S9 and S10).

On the other hand, when the user U1 is not “Mr. Yutaka”, after face recognition at the closest position P0, the user leaves the close position P0 before the closeness determination time (for example, 30 seconds) elapses (S21).
In this case, similarly to the indoor unit 100 of the first embodiment, the movement of the user U1 is tracked, and the concentrated blowing is continued toward the user position P1 (in this case, the user position P1 is different from the closest position P0). Again, when a predetermined time (for example, 30 minutes) has passed, it is determined whether or not the user U1 has moved from the user position P1 (see S11 in FIG. 6). The processes after making such a determination are the same as those of the indoor unit 100 of the first embodiment.

As described above, since the indoor unit 200 according to the second embodiment performs the above-described steps (processes), the user U1 who is hot water just stands at the closest position P0 without operating the remote controller or the like. The refrigeration cycle can be started quickly, and as long as the refrigeration cycle continues to stand at the closest position P0, it is possible to cool by concentrated blowing until the closest blowing time elapses.
Then, at the time when the closest blowing time has elapsed or when the user U1 who is hot water has left the closest position P0 (corresponding to the time when it can be considered that cooling has ended), the concentrated blowing is stopped, and the distributed blowing is performed. To start.

Therefore, the user U1 who is hot water can start cooling easily and quickly without operating the remote control, and the concentrated wind flow without operating the remote control etc. after cooling is finished. You can enjoy a comfortable air-conditioning environment.
On the other hand, for the user U1 who is not hot water but is hot (or cold), or the user U2 who is not hot but is not hot (or cold), the room of the first embodiment is used. As with the machine 100, comfort is maintained.

[Embodiment 3]
10 and 11 illustrate an indoor unit of an air conditioner according to Embodiment 3 of the present invention. FIG. 10 is a temperature change diagram schematically showing a temperature change in swing blowing, and FIG. It is a flowchart which shows a control step. In addition, the same code | symbol is attached | subjected to the same site | part or the same step as Embodiment 2, and some description is abbreviate | omitted.
The indoor unit (hereinafter referred to as “indoor unit”) 300 of the air conditioner according to the third embodiment is indoors from the outside of a bath or from a hot (or cold) outdoor, like the indoor unit 200 (second embodiment). Immediately after entering, it responds to the request of a user (hereinafter referred to as “Yamago-san”) who wants to cool quickly (want to warm) temporarily.

In the indoor unit 200 shown in the second embodiment, when the user U1 is “Mr. Hot Spring”, the concentrated blowing is performed toward the closest position P0, and the closest blowing time (for example, 10) until the cooling ends. Concentrated blowing is continued during (minute) (see S22 in FIG. 9), and when the nearest blowing time (for example, 10 minutes) has passed, the system shifts to dispersed blowing (see S9 and S10 in FIG. 6).
However, since the closest blowing time, which is a predetermined time until the cooling (warming) ends, is not constant depending on the warming (cooling) condition of the user U1, the indoor unit 300 replaces the closest blowing time with the body temperature of the user U1. The timing for shifting to distributed blowing is determined by paying attention to changes in

The indoor unit 300 is provided with a temperature measuring means (temperature sensor, not shown) that can detect the surface temperature of the face of the user U1 standing at the closest position P0. The up / down wind direction plate 9 and the left / right wind direction plate 10 are controlled based on the human position information and the human body temperature information detected by the temperature detecting means.
Then, the conditioned air is intermittently and repeatedly blown out to the user U1 who is “Mr. Yutaka” standing at the closest position P0 (hereinafter referred to as “swing blowout”).
That is, the up-and-down wind direction plate 9 is rotated to blow conditioned air toward the face of the user U1 for a predetermined time, and for the next predetermined time, the conditioned air is directed toward the user U1. The cycle in which the air is not blown out (blows the conditioned air toward the face other than the face of the user U1) is repeated. Instead of the up / down wind direction plate 9, the left / right wind direction plate 10 may be rotated to perform the same swing blowing.

  FIG. 10 schematically shows a change in the temperature of the face of the user U1 during swing blowing. In FIG. 10, when the surface temperature of the face immediately after the hot water is the temperature T0, the face surface temperature is first lowered to the temperature T1 by the first concentrated blowing on the face. Therefore, when the concentrated blowing to the face is interrupted, the face surface is reheated and the surface temperature rises to the temperature T2. Then, by the second concentrated blowing on the face, the face surface temperature decreases to the temperature T3, and when the concentrated blowing on the face is interrupted, the surface temperature rises to the temperature T4. Thereafter, the face temperature at the time of concentrated blowing and the surface temperature of the face after recuperation gradually decrease by intermittent repetition of concentrated blowing.

At this time, the degree of decrease in the surface temperature of the face after recuperation due to repeated swing blowing (difference between temperature T2 and temperature T4, etc.) is the degree of decrease in the surface temperature of the face during concentrated blowing due to repeated swing blowing. (Difference between temperature T1 and temperature T3, etc.).
Therefore, a decrease amount ΔT01 of the face surface temperature due to the first concentrated blow (difference between the temperature T0 and the temperature T1), an increase amount ΔT12 of the face surface temperature due to the first reheating (a difference between the temperature T2 and the temperature T1), Decrease amount ΔT23 of the face surface temperature due to the second concentrated blow (difference between temperature T3 and temperature T2) Increase amount ΔT34 of the face surface temperature due to the second recuperation (difference between temperature T4 and temperature T3) In order, it becomes gradually smaller.
A comfortable temperature range ΔTa (for example, 1 ° C.) in which the amount of decrease in the surface temperature of the face due to concentrated blowing or the amount of increase in the surface temperature of the face due to recuperation (hereinafter referred to as “body temperature fluctuation range ΔT”) ) It is considered that the user U1 feels refreshing (feels cool or warm) when the following occurs.

In FIG. 11, the indoor unit 300 starts concentrated blowing toward the user position P1 standing at the closest position P0 (see S7 in FIG. 5), and continues the concentrated blowing (see S8 in FIG. 5). Then, it is determined whether or not the user U1 remains in the close position P0 (continues to stand) even after the closeness determination time (for example, 30 seconds), which is a predetermined time, has elapsed (S31).
Then, if the user stays at the closest position P0 (continues to stand) even after the closest determination time has elapsed, it is determined that the user U1 is “Mr. Hot Spring” and the swing blowing is started (S32). The swing blowing continues until the user U1 feels refreshing (feels cool or warm), that is, until the fluctuation range ΔT of the body temperature is equal to or less than the predetermined comfortable temperature range ΔTa (ΔT> ΔTa) (S34), When the fluctuation range ΔT of the body temperature becomes equal to or less than the predetermined comfortable temperature range ΔTa (ΔT ≦ ΔTa), the process shifts to the dispersion blowing (see S9 and S10 in FIG. 6).

  In addition, when the user U1 leaves the closest position P0 before the body temperature fluctuation width ΔT becomes equal to or less than the predetermined comfortable temperature width ΔTa (ΔT> ΔTa) (S33), the dispersion is performed at the time of the separation. The process shifts to blowing (see S9 and S10 in FIG. 6).

On the other hand, when the user U1 is not “Mr. Yutaka”, after face recognition at the closest position P0, the user leaves the close position P0 before the closeness determination time (for example, 30 seconds) elapses (S31).
In this case, similarly to the indoor unit 100 of the first embodiment, the movement of the user U1 is tracked, and the concentrated blowing is continued toward the user position P1 (in this case, the user position P1 is different from the closest position P0). Again, when a predetermined time (for example, 30 minutes) has passed, it is determined whether or not the user U1 has moved from the user position P1 (see S11 in FIG. 6). The processes after making such a determination are the same as those of the indoor units 100 and 200 of the first and second embodiments.

As described above, since the indoor unit 300 according to the third embodiment executes the steps (processes), the user U1 who is hot water just stands at the closest position P0 without operating the remote controller or the like. The refrigeration cycle can be started quickly, and until the user U1 feels refreshing (feels cool or warm), it becomes possible to quickly cool (warm) by concentrated blowing, and also feel refreshed. After that, it becomes possible to cool gently (warm up) by dispersed blowing without operating a remote controller or the like.
Therefore, the user U1 who is hot water can start cooling easily and quickly without operating the remote control, and the concentrated wind flow without operating the remote control etc. after cooling is finished. You can enjoy a comfortable air-conditioning environment.
On the other hand, for the user U1 who is not hot water but is hot (or cold), or the user U2 who is not hot but is not hot (or cold), the room of the first embodiment is used. As with the machine 100, comfort is maintained.

Finally, the body temperature fluctuation range ΔTc will be described.
Even if the fluctuation range ΔT of the body temperature is the amount of decrease in the surface temperature of the face due to concentrated blowing at a certain repetition (in the first case, ΔT = ΔT01 = T0−T1), the increase in the surface temperature of the face due to recuperation An amount (for example, ΔT = ΔT12 = T2−T1) may be used, or an average value of both (ΔT = (ΔT01 + ΔT12) / 2) may be used.
Further, the average value of the amount of decrease in the surface temperature of the face due to multiple concentrated blows and the amount of increase in the surface temperature of the face due to recuperation (in the first and second examples, ΔT = (ΔT01 + ΔT12 + Δ23 + Δ34) / 4) There may be. By using the average value of the amount of decrease and the amount of increase over a plurality of times, it is possible to make a determination while suppressing the influence of actual surface temperature and variations in temperature detection.
