Description

  The present invention relates to an indoor unit of an air conditioner, and more particularly to an indoor unit of an air conditioner that can change the blowing direction of conditioned air.

Conventionally, in order to increase the comfort of human beings in the room (hereinafter referred to as “occupants”), the position of the occupant is detected and air is blown to avoid the occupant, or the occupant is opposed to An air conditioner indoor unit (hereinafter referred to as an “indoor unit”) that blows air toward the air is known.
And not only simply detecting the position of the occupant, but also detecting the activity state of the occupant and controlling the blowing temperature, blowing amount and blowing direction of the conditioned air based on the activity state, When it is detected that the amount of activity is increasing due to light exercise or light hard work, it blows intensively toward the occupant (hereinafter referred to as "user") and removes the amount of heat generated by the activity. Thus, an indoor unit is disclosed that suppresses an increase in body temperature so that it does not feel hot (see, for example, Patent Document 1).

JP-A-6-323599 (page 3-5, FIG. 2)

However, in the indoor unit disclosed in Patent Document 1, conditioned air is not concentrated and blown toward a user whose activity amount is not large, and normal blowing is performed. For this reason, even if the user does not have a large amount of activity, the perceived temperature is different personally, the user who feels hot with normal air blowing (hereinafter referred to as “Hatsugari-san”) and the user who feels cold (hereinafter referred to as “Hot-san”) Therefore, there is a request to maintain the comfort of the hot and cold people.
Further, immediately after entering the room from the hot (or cold) outdoors, there is a demand to search for a remote control (remote control device), eliminate the trouble of starting operation, and quickly cool (want to warm). In particular, immediately after entering a room from a bath or hot (or cold) outdoors, there is a demand to temporarily cool (want to warm).
Furthermore, there is a request to receive conditioned air easily (expose to the air flow) without troublesome operation of the remote control (remote control device), although it does not cool down rapidly (warm up) temporarily. There is.

  The present invention is an air conditioner indoor unit that responds to the above demands and can rapidly improve the comfort of users with different body temperatures without requiring the operation of a remote control or the like. To get.

  The indoor unit of the air conditioner according to the present invention has a suction port and an air outlet, respectively, and a main body installed on a wall surface of the room, and an air path that sucks indoor air from the air inlet and reaches the air outlet. A blower to be formed, a heat exchanger installed in the air passage and executing a part of the refrigeration cycle, and a wind direction adjusting device installed in the outlet and adjusting the air blowing direction harmonized in the heat exchanger An imaging device that images the room, a temperature measuring device that detects the body temperature in the room, the position information of the person imaged by the imaging device and the human temperature information detected by the temperature measuring device, A control device that controls the wind direction adjusting device, wherein the control device is in a face recognition range within the field of view of the imaging device for a face recognition time that is a predetermined time. This When recognizing a human face and the body temperature of the person whose face is recognized deviates from a temperature within a preset standard temperature range, the conditioned air blowing temperature is changed to the conditioned air blowing temperature currently being operated or The temperature is set to a temperature different from the temperature of the conditioned air that was set when the operation was stopped last time, and the air is blown toward the position where the person with the recognized face or the person with the recognized face is located. When the body temperature of the person whose face is recognized falls within the standard temperature range by blowing the conditioned air at the blown air temperature, the conditioned air blow temperature is set to the pre-set blow temperature. The returning control is executed.

The indoor unit of the air conditioner according to the present invention recognizes a human face approaching the main body and detects the body temperature of the human body (hereinafter referred to as “user”) whose face has been recognized. If the temperature is low, the user enters the room from a cold place, determines that the user is about to warm up quickly, sends conditioned air to the user with a high blowout temperature, and if the user's body temperature is high, If the user enters the room from a hot place, determines that he is trying to cool quickly, sends conditioned air with a low blowing temperature to the user, and if the user's body temperature is neither low nor high, The user simply determines that the conditioned air is going to be blown toward him and sends the conditioned air to the user without changing the blowing temperature.
Therefore, a user who enters a room from a cold place or a person who enters a room from a hot place can quickly warm up or cool down at a nearby location or destination without needing to operate a remote control. Convenience is improved.
In addition, a user who simply tries to blow out conditioned air toward himself / herself does not require operation of a remote controller or the like, and conditioned air without changing the blowing temperature at a close position or a moving destination. Since it is sent, that is, it is distinguished from the user who entered the room from a cold place and the user who entered the room from a hot place, and is not exposed to undesired warm conditioned air or cold air, comfort and convenience are improved.
Further, when the temperature is sufficiently warm or cool, the operation is not returned to the pre-setting air temperature without requiring operation of a remote controller or the like, so that comfort and convenience are improved.

(User face recognition)
FIG. 4 is a side view for explaining a user face recognition procedure in the indoor unit of the air conditioner shown in FIG. 1.
In FIG. 4, the indoor unit 100 is installed at a position close to the ceiling surface 92 on one wall 91 (hereinafter referred to as “back wall”) of the room 90.
In addition, the imaging apparatus (for example, a 300,000 pixel CCD camera) 50 has a field of view 51 that faces obliquely downward. Then, within the field of view 51, the face of the user U1 is within a range 52 (shown by diagonal lines in the figure, hereinafter referred to as “face recognition range”) within the distance L1 to the distance L2 (> L1) from the imaging device 50. When F1 is present, 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 70 determines that “the user U1 is trying to recognize the indoor unit 100 itself”, and from the distance L3. However, when there is no face F1 in the face recognition range 52, a notifying means (not shown) is informed of that fact.
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 U1 is closer than the distance L3 (> L2) from the imaging device 50 and does not recognize the face F1 until a predetermined face recognition time (for example, 2 seconds) elapses (the face F1 is recognized as the face recognition range). When the user U1 does not enter the control unit 52), it is determined that “the user U1 is not trying to cause the indoor unit 100 to recognize himself / herself”, that is, it is not necessary to perform the control described later.
At this time, a notification means (not shown) may notify the fact. For example, a notification such as “I will drive in the operation mode at the end of the previous time” is given by voice, or a lamp indicating “Operation in the operation mode at the time of the previous end” is lit or blinked.

(User tracking)
After recognizing the face F1 of the user U1, the control device 70 tracks the user U1 from the image of the user U1 captured by the imaging device 50, and specifies the destination (hereinafter referred to as “user position”) P1. To do.
That is, while the user U1 does not move and the face F1 remains in the face recognition range 52, the closest position P0 corresponding to the face recognition range 52 is specified as the user position P1. Also, immediately after recognizing the face F1, the user U1 moves away from the indoor unit 100, and after such movement, that is, the position where the user U1 stops or sits is specified as the user position P1. To do.

(Determination of body temperature of user's face)
The body temperature of the user U1 at the user position P1 is specified based on the indoor temperature (more precisely, temperature distribution) detected by the temperature measuring device 60. When the specified body temperature is out of the predetermined “standard temperature range”, the conditioned air blowing temperature is changed as described below.
Note that when the imaging device 50 does not recognize a face or during driving, the control described below is not performed.

(Setting of blowing temperature)
When the specified body temperature is higher than the upper limit temperature (for example, 38 ° C.) of the predetermined “standard temperature range”, the user U1 enters the room from a hot outdoor room or is out of the bath and quickly cools down. If it is determined that it is going to be performed, the conditioned air blowing temperature is changed to a temperature lower than the conditioned air blowing temperature at that time (for example, a temperature lower by 5 ° C.) If it is currently stopped, the temperature is changed to a temperature lower than the conditioned air blowing temperature set when the previous operation was stopped (for example, a temperature lower by 5 ° C.) (strong blowing, high power blowing). .

  On the other hand, when the specified body temperature is lower than the predetermined lower limit temperature (for example, 35 ° C.) of the “standard temperature range”, it is determined that the user U1 enters from a cold outdoor room and is about to warm up rapidly. When the conditioned air blowing temperature is currently in operation, the conditioned air blowing temperature is changed to a temperature higher than the conditioned air blowing temperature at that time (for example, a temperature higher by 5 ° C.) and is currently stopped. In this case, the temperature is changed to a temperature (for example, a temperature higher by 5 ° C.) than the conditioned air blowing temperature set when the previous operation was stopped (strong blowing).

  In addition, when the specified body temperature is a temperature within a predetermined “standard temperature range” (for example, 35 to 38 ° C.), the user U1 causes the conditioned air to be intensively blown toward the user. If it is determined that the conditioned air is currently being operated, the conditioned air blowing temperature remains the same as the conditioned air blowing temperature at that time. Is set to the same temperature as the conditioned air blowing temperature that was set when the operation was stopped (standard blowing).

(Control flow)
5 and 6 are flowcharts showing a control flow in the indoor unit of the air conditioner shown in FIG.
5 and 6, when the face F1 of the user U1 is in the face recognition range 52 at least during the face recognition time (S1), the control device 70 recognizes the face F1 (face recognition step, S2). Then, the temperature measuring device 60 starts detecting the body temperature (T1) of the user U1 whose face F1 is recognized (S3). It is determined whether or not the body temperature (T1) is within a preset standard temperature range (body temperature determination step, S4).

When the body temperature (T1) is higher than the upper limit temperature (TU) of the standard temperature range (T1> TU), the conditioned air blowing temperature is set at the current conditioned air blowing temperature or when the previous operation is stopped. It sets to the blowing temperature (T-ΔT) lower than the blowing temperature of the conditioned air that has been set (temperature setting step, S5-1).
Further, when the body temperature (T1) is lower than the lower limit temperature (TL) of the standard temperature range (T1 <TL), the conditioned air blowing temperature is set when the conditioned air blowing temperature during the current operation or when the previous operation is stopped. It sets to the blowing temperature (T + ΔT) which is higher than the blowing temperature of the conditioned air which has been done (Temperature setting step, S5-2).
Further, when the body temperature (T1) is within the standard temperature range (TL ≦ T1 ≦ TU), the conditioned air blowing temperature is set to the conditioned air blowing temperature currently being operated or the harmonizing that was set when the previous operation was stopped. The same blowing temperature (T) as the blowing temperature of air is set (temperature setting step, S5-3).

Then, it is determined whether the refrigeration cycle is operating (cooling operation, heating operation, etc.) or stopped (S6), and if it is stopped, the refrigeration cycle is started (S7).
Therefore, conditioned air is blown out toward the user U1 or the closest position P0 where the user U1 is standing (powerful blowing step, S8).
Then, it is determined whether or not the user U1 has moved from the closest position P0 (a range immediately below the face recognition range 52) to another position (S9).

Then, for the user U1 who remains at the closest position P0, it is determined whether or not the body temperature (T2) of the user U1 detected by the temperature measuring device 60 is within a preset standard temperature range (temperature return step, S10).
Therefore, when it is determined that the body temperature (T2) is within the standard temperature range (TL ≦ T2 ≦ TU), the conditioned air blowing temperature is returned to the blowing temperature (T) before being set (temperature returning step). , S11).
And after returning to the blowing temperature (T) before the blowing temperature is set, the left and right wind direction plates 10 and the upper and lower wind direction plates 10 so that the conditioned air of the blowing temperature (T) is sent toward the user U1 or the closest position P0. The attitude of the wind direction plate 9 is controlled (standard blowing step, S12), and step 12 is repeated until an end button provided on a remote controller (not shown) is pressed.
On the other hand, if the detected body temperature (T2) remains at a temperature outside the standard temperature range (TL ≦ T2 ≦ TU) in step 10, the process returns to step 8 to continue the powerful blowout.

  Furthermore, when it is determined in step 9 that the user U1 has moved, the user U1 is tracked, the position of the user U1 is specified (S13), and the set blowing is set toward the user position P1 that is the specified position. The postures of the left and right wind direction plates 10 and the upper and lower wind direction plates 9 are controlled so that conditioned air of temperature (T + ΔT or T−ΔT) is sent (tracking powerful blowing step, S14).

Furthermore, when the body temperature (T2) of the user U1 detected by the temperature measuring device 60 becomes a temperature within the preset standard temperature range (TL ≦ T2 ≦ TU) or when the temperature is within the standard temperature range from the beginning. (S15) The set blowing temperature is returned to the temperature (T) before the setting (tracking temperature returning step, S16). As long as the body temperature (T2) is outside the standard temperature range (T2 <TL, TU <T2), the tracking powerful blowing step (S14) is continued.
Then, following the tracking temperature return step, the postures of the left and right wind direction plates 10 and the upper and lower wind direction plates 9 are controlled so as to send conditioned air at the blowing temperature (T) before being set toward the user position P1 (tracking). Standard blowing step, S17).
When the end button provided on the remote controller (not shown) is pressed, the operation of the refrigeration cycle is stopped. On the other hand, if the end button is not pressed, the process returns to step 17 to continue the tracking standard blowing step. In any step after step 1, if the end button is pressed (not shown), the operation of the refrigeration cycle is stopped.

Since the indoor unit 100 executes the above control flow, the following operational effects can be obtained.
A user who has entered a room from a cold (hot) place has a low (high) body temperature, and is quickly warmed (cooled) by strong conditioned air (the blowing temperature is changed) by standing at the closest position P0 of the indoor unit 100. Can do. In addition, when the user U1 moves from the closest position P0 before the user U1 is sufficiently warmed (cooled), the user U1 is tracked and the strong conditioned air (the blowing temperature is changed at the specified position). ) Can quickly warm (cool).
On the other hand, the user who wants to blow the conditioned air currently being operated (the blowing temperature is not changed) toward the user receives the conditioned air currently being operated by standing at the closest position P0 of the indoor unit 100. be able to.

Furthermore, since the operation is started when the operation is stopped, the trouble of searching for a remote control or the like can be saved. Therefore, it is possible to quickly warm (cool) without requiring special work, and convenience and comfort are increased.
Furthermore, when the user U1 is warmed (cooled), the “non-powerful conditioned air” that has been returned to the temperature before the change of the blowing temperature is sent to the user position P1, so that special work is required. And enjoy a comfortable air-conditioning environment.

Note that even if the user U1 continues to stand at the closest position P0 and the body temperature (T2) remains outside the standard temperature range (T2 <TL, TU <T2), the conditioned air blowing temperature is set. In such a case, the user U1 once leaves the closest position P0 and recognizes the face F1 again.
In addition, although it described so that the blowing temperature of conditioned air may be set (changed, maintained), the refrigerant temperature in the refrigeration cycle (for example, the outlet temperature of the compressor, the refrigerant expansion valve, or the like) is used instead of the blowing temperature. Or the like may be set. Furthermore, you may set (change and maintain) the rotation speed of the air blower 5 according to the setting of the blowing temperature of conditioned air.

(Blowout procedure)
FIG. 7 is a plan view for explaining the conditioned air blowing procedure in the indoor unit of the air conditioner shown in FIG. 1.
The above shows what is continuously blown toward the user position P1, but the present invention is not limited to this, and the user position P1 is switched by switching the “blower mode” by operating a remote controller or the like. Alternatively, the air may be intermittently sent (hereinafter referred to as “swing air”).
Further, a predetermined time (hereinafter referred to as “dispersed blowing start time”, for example, 15 minutes) is determined by an operation of the remote controller or the like, and after the distributed blowing start time has elapsed, the position is limited to the user position P1. Alternatively, the conditioned air may be uniformly sent over a wide range in the room (distributed blowing). Each will be described below.

(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 enters the room 90 from the outside where the temperature is high (or low), the user U1 does not need to search for the remote control and press the operation start button installed on the remote control. You can start a powerful (high-power) operation just by moving it closer to. Moreover, if the user moves and stops or sits after starting the strong driving, the position is automatically specified as the user position P1, and strong cold air or warm air (the blowing temperature is set to the user position P1). It is not necessary to operate the remote control etc. to ensure that conditioned air reaches your location. Therefore, convenience and comfort are improved. That is, a local “strong cool feeling (high power cool) mode” or “strong warm feeling (high power hot) mode” is realized for the user U1.

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 air outlet 7 immediately after being blown out, but mixes with the surrounding air while flowing through the room 90. Therefore, the air flow when actually reaching the user position P1 has a large cross section compared to the size of the blowout port 7, and in the cross section, the flow direction and the flow velocity are various. It is a set of flow bundles.
For this reason, “the conditioned air is sent toward the user position P1” and “concentrated blowout” in the present invention mean that the center when the spread air flow is averaged is “toward a specific position”. This means that conditioned air has also reached around the user position P1.

(Dispersed blowing)
7A or 7B, the left and right wind direction plate group 10L is always fixed in a posture in which conditioned air is blown out toward the user position P1, and the right and left wind direction plate group 10R has the user position P1 and the user position P2. Rotating (swinging) so as to blow out conditioned air while reciprocating within a predetermined range (indicated by α in the figure).
Then, since a larger amount of conditioned air is intensively blown toward the user U1 whose face F1 is recognized, the comfort of the user U1 is improved, and a smaller amount is included in the range excluding the user position P1. The conditioned air will be blown out intermittently.
For this reason, when the user U2 who does not want to be exposed to the direct wind flow is in the user position P2, which is a position different from the user position P1, a smaller amount of conditioned air is intermittently blown out to the user position P2. Therefore, the comfort of the user U2 is also maintained.

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 whose face F1 is recognized, the comfort of the user U1 is improved, and a smaller amount is included in the range excluding the user position P1. The conditioned air will be blown out intermittently.
For this reason, when the user U2 whose body temperature (or sensible temperature) is different from the user U1 is in the user position P2, which is a position different from the user position P1, a smaller amount of conditioned air is intermittently present in the user position P2. Therefore, the comfort of the user U2 is also maintained.

(Swing blowout)
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, as in the case shown in FIG. 7B, the comfort of the user U2 whose body temperature (or sensory temperature) is different from the user U1 is maintained together with the user U1 whose face F1 is recognized. .
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 addition, you may make it wind intermittently toward the user position P1, synchronizing both rotation (swing) of 10R of right right / left wind direction board groups and 10L of left left / right wind direction board groups.
At this time, the body temperature of the user U1 apparently recuperates during a time period in which no ventilation is received. In other words, the average body temperature of the user U1 who entered the room from a cold (hot) place gradually rises (falls) in the powerful blowout step, but the temperature actually detected by the temperature measuring device 60 is subject to air blowing. Compared to the time zone, the time zone where the air is not received is lower (eyes). Therefore, it is preferable to set the temperature detected by the temperature measuring device 60 as the “body temperature” in a time zone during which no air is received (blowing out other than the user position P1).
