うものであった。BACKGROUND ART Conventionally, air conditioners generally detect conditions such as temperature, humidity, and air flow in a room to be air-conditioned, and control air volume, air direction, blowing temperature, etc. based on these conditions.
ところが、上記の制御方法では、温度、湿度などの条件

同様に生じるものである。However, with the above control method, if conditions such as temperature and humidity are the same, the same control is performed regardless of the activity status of the occupant in the room. If the occupants are sitting quietly, there will be discomfort due to excessive cooling and fan noise; conversely, if the occupants are active in the room, there will be a feeling of insufficient cooling. There was a problem in that it was difficult to control the air conditioning according to the activity status of the residents. In such a case,
In order to obtain an appropriate cooling condition, manual adjustment is required, which makes the operation complicated. Note that although the above description has been made regarding cooling, the above-mentioned problems also occur during heating.

手段とを備えていることを特徴とするものである。In order to solve the above-mentioned problems, an air conditioner according to the present invention includes an infrared ray detection means for detecting the amount of infrared radiation;
A rotating scanning means rotates the infrared detecting means to scan each direction in the room, and the amount of infrared radiation detected by the infrared detecting means from each direction inside the room is read at predetermined time intervals to detect the occupant's activities. The air conditioner is characterized by comprising a control means for detecting the state and controlling the air conditioning state according to the detected activity state of the occupant.
上記の構成を有する本発明は、居住者の人体からの赤外

ように制御を行うものである。The present invention having the above configuration focuses on the fact that the amount of infrared rays radiated from the human body of a resident is considerably larger than the amount of infrared rays radiated from the surrounding environment. presence or absence of residents based on the amount of infrared radiation of
If there is a resident, the location is detected, and the resident's activity status is also detected based on temporal changes in the resident's location, so that air conditioning conditions suitable for the resident's activity status can be obtained. It controls the
例えば、冷房時には、冷房を行っている室内での居住者
の活動量が少なければ、換言すれば、室内の各方向から
の赤外線の放射量の時間的変化が少なければ、それに応
じて冷房量を小さくして過剰冷房の防止及び騒音の抑制
を図ることができる。For example, during cooling, if the amount of activity of the occupants in the room being cooled is low, or in other words, if the amount of infrared radiation emitted from each direction in the room changes little over time, the amount of cooling should be adjusted accordingly. By making it smaller, excessive cooling can be prevented and noise can be suppressed.

とができる。On the other hand, if the amount of activity of the occupants is large, that is, if there is a large temporal change in the amount of infrared radiation emitted from each direction in the room, the amount of cooling will be increased accordingly to obtain a sufficient cooling state. can do. In this case, the amount of cooling is adjusted, for example, by adjusting the air volume and the blowing temperature. Furthermore, during heating, control can basically be performed in the opposite manner to that during cooling.
なお、空調の制御に際しては、居住者の活動状態ばかり
でなく、これに、室内の温度、湿度、気流なども加味し
て制御を行うことができるのは言うまでもない。It goes without saying that when controlling the air conditioning, it is possible to control not only the activity status of the occupants but also the indoor temperature, humidity, airflow, etc.
本発明の一実施例を第１図乃至第６図に基づいて説明す

８に入力させる役割を果たす。As shown in FIG. 2, the infrared temperature detection device 2 includes an infrared sensor 8 as an infrared detection means that detects infrared rays emitted from a human body 6 of a resident through a lens 7. In order to accurately detect the position of the occupant in the room, the lens 7 limits the direction in which the infrared sensor 8 detects infrared rays, thereby giving the infrared sensor 8 directivity and efficiently transmitting infrared rays. It plays the role of inputting information to the infrared sensor 8.

８で空調を行うべき部屋の中の各方向を隈なく走査でき
るようになっている。The infrared sensor 8 is connected to the drive motor 1 as a rotation scanning means.
It is attached to one end of the output shaft 11 of 0. Since the one end of the output shaft 11 is bent, the central axis of the infrared sensor 8 is inclined with respect to the central axis of rotation of the drive motor 10. As a result, by rotating the infrared sensor 8 with the drive motor 10, the infrared sensor 8 can scan every direction in the room to be air-conditioned.

is installed. Incidentally, the power signals from the infrared sensor 8 and the scanning angle detector 12 are sent to the main control section 1.
以下、上記空気調和装置の作動について述べる。The operation of the air conditioner will be described below.

れぞれ所定時間間隔で検出される。When the above-mentioned air conditioner is operated, air at a predetermined temperature is blown into the room to be air-conditioned by the indoor blower 5. Further, at the same time as the infrared sensor 8 is activated, the infrared sensor 8 is rotated at a predetermined rotational speed by the drive motor 10, and the amount of infrared radiation from each direction in the room is detected at predetermined time intervals. .

体的には、風量及び吹出温度の制御が行われる。Based on the temporal changes in the amount of infrared radiation from each direction in the room detected by the infrared sensor 8,
The main control unit 1 detects the activity status of the occupant in the room, and the main control unit 1 determines the air conditioning status according to the activity status of the occupant and the room temperature detected by the room temperature detector 3. The air volume and blowing temperature are controlled.
次に、主制御部ｌに送られる赤外線センサ８の出力信号
の波形の具体例を第３図に示す。Next, a specific example of the waveform of the output signal of the infrared sensor 8 sent to the main control section 1 is shown in FIG.

大値Ｐが現れる。This graph shows the relationship between each direction in the room and the amount of infrared radiation from each direction, and shows the relationship between the infrared sensor 8
If there is a resident within the scanning range, the maximum value P will appear in the direction of the resident.
赤外線センサ８による部屋の中の各方向からの赤外線の
放射量の検出は所定時間間隔で繰り返し行われるが、そ
の場合、居住者が部屋の中で活発に活動していれば、居
住者の存在する位置の時間的変化が大きいので、第４図

る赤外線センサ８の出力波形Ａと、点線で表した前回の
走査時における赤外線センサ８の出力波形Ｂとの間に、
第５図（ａ）に示すような、大きなずれが生じることに
なる。The infrared sensor 8 detects the amount of infrared radiation from each direction in the room repeatedly at predetermined time intervals. Since the temporal change in the position is large, as shown in FIG. 4(a), the output waveform A of the infrared sensor 8 during the current scan is represented by a solid line, and the infrared sensor during the previous scan is represented by a dotted line. Between output waveform B of 8,
A large deviation as shown in FIG. 5(a) will occur.
なお、例えば、冷房を行うに際して、上記のように、単
位時間内での赤外線センサ８の出力波形Ａ−Ｂの差が大
きく、従って、部屋の中での居住者の活動量が大きい場
合は、風量が多めに、かつ、吹出温度が低めになるよう
に制御される。For example, when performing air conditioning, as described above, if the difference between the output waveforms A and B of the infrared sensor 8 within a unit time is large, and therefore the amount of activity of the occupant in the room is large, The air volume is controlled to be high and the blowing temperature to be low.
一方、空調を行っている部屋の中での居住者の活動量が

僅かなものとなる。On the other hand, if the amount of activity of the occupants in the air-conditioned room is low, as shown in Figure 4 (a), the 8th output waveform of the infrared sensor during the current scan, represented by solid line C, , the infrared sensor 8 at the time of the previous scan indicated by the dotted line
As shown in Figure 5(b), the difference between the output waveform of
It becomes a small amount.

が少なめに、かつ、吹出湯度が高めになるように制御さ
れ、冷房が抑制される。During cooling, when the difference between the output waveforms C and D of the infrared sensor 8 within a unit time is small and the amount of activity of the occupants in the room is small, the air volume is reduced accordingly. In addition, the temperature of the hot water blown out is controlled to be high, and cooling is suppressed.
次に、第６図のフローチャートを参照しながら、空気調
和装置により冷房を行う場合の主制御部１による具体的
な制御例を述べる。Next, with reference to the flowchart in FIG. 6, a specific example of control by the main control unit 1 when cooling is performed by the air conditioner will be described.
ここでは、部屋の中の各方向からの赤外線の放射量の検
出を１″間隔で行うようになっている。Here, the amount of infrared radiation from each direction in the room is detected at 1'' intervals.
まず、走査角検出器１２の出力信号を読み込み、これに
より、赤外線センサ８の走査角、つまり、その時点で、
赤外線センサ８がいずれの方向を向いているかを検出す
る（Ｓｌ）。First, the output signal of the scanning angle detector 12 is read, and thereby the scanning angle of the infrared sensor 8, that is, at that point,
It is detected which direction the infrared sensor 8 is facing (Sl).
続いて、赤外線センサ８の出力信号を読み込み、これに
より、Ｓｌで検出した方向からの赤外線の放射量を求め
て、方向と放射量とを対応させて記憶する（３２）。Subsequently, the output signal of the infrared sensor 8 is read, and thereby the amount of infrared radiation from the direction detected by Sl is determined, and the direction and the amount of radiation are stored in correspondence (32).
次に、Ｓｌで検出した方向からの今回の赤外線の放射量
を表す赤外線センサ８の今回の出力信号と、同じ方向か
らの前回の赤外線の放射量を表す赤外線センサ８の前回
の出力信号との差Ｖ ｄｉｆを計算する（Ｓ３５゜そし

１″間隔で求めた、今回と前回の赤外線センサ８の出力
信号の差Ｖｄ１ｆの累算値Ｖｄ１ｆ ’に加算し、１″
間隔の各方向からの今回と前回の赤外線センサ８の出力
信号の差の累算値Ｖｄ１ｆ ’を更新する（Ｓ４）。Next, the current output signal of the infrared sensor 8 representing the current amount of infrared radiation from the direction detected by Sl and the previous output signal of the infrared sensor 8 representing the previous amount of infrared radiation from the same direction are compared. Calculate the difference V dif (S35゜Then, the obtained difference Vd1f is calculated as the cumulative value Vd1f of the difference Vd1f between the output signals of the current and previous infrared sensor 8, which are obtained at intervals of 1" of the scanning angle of the infrared sensor 8. 'Add to 1''
The cumulative value Vd1f' of the difference between the current and previous output signals of the infrared sensor 8 from each direction of the interval is updated (S4).
続いて、赤外線センサ８の走査角を１°進めた（Ｓ５）
後、走査角が３６０ ”に達したか否か、換言すれば、
赤外線センサ８が１回転したか否かを判定する（Ｓ６）
。そして、走査角が３６０＠に達していなければ、Ｓｌ
に戻り、上述と同様の処理を繰り返す。Subsequently, the scanning angle of the infrared sensor 8 was advanced by 1° (S5)
After that, whether the scanning angle reaches 360'' or not, in other words,
Determine whether the infrared sensor 8 has rotated once (S6)
. Then, if the scanning angle does not reach 360@, Sl
Return to and repeat the same process as above.
一方、Ｓ６で走査角が３６０ ’に達していれば、赤外
線センサ８が１回転したので、走査角を０″に戻した（
Ｓ７）後、赤外線センサ８が１回転する間の今回と前回
の出力信号の差の累算値Ｖｄ１ｆ ’が予め設定した基
準値Ｖｃ以上であるか否かを判定する（Ｓ８）。On the other hand, if the scanning angle had reached 360' in S6, the infrared sensor 8 had rotated once, so the scanning angle was returned to 0'' (
After S7), it is determined whether the cumulative value Vd1f' of the difference between the current and previous output signals during one rotation of the infrared sensor 8 is greater than or equal to a preset reference value Vc (S8).
そして、累算値Ｖｄ１ｆ ’が基準値Ｖｃ以上であれば
、空調を行っている部屋の中での居住者の活動量が大き
いものとみなされて、室内送風機５により送り出される
風量が多めに設定されるとともに、吹出温度が低めにな
るように制御され、十分な冷房状態が得られるようにさ
れる（Ｓ９）。この場合、居住者は活発に活動している
ので、冷房を強くすることによる多少の騒音の増加は居
住者にさほど不快感を与えないものである。If the accumulated value Vd1f' is equal to or greater than the reference value Vc, it is assumed that the amount of activity of the occupant in the room being air-conditioned is large, and the air volume sent out by the indoor fan 5 is set to be large. At the same time, the blowing temperature is controlled to be low, so that a sufficient cooling state can be obtained (S9). In this case, the occupants are active, so the slight increase in noise caused by increasing the cooling power does not cause much discomfort to the occupants.
一方、累算値Ｖｄ１ｆ ’が基準値Ｖｃより小さければ
、部屋の中での居住者の活動量が小さいものとみなされ
、それに基づいて、風量が少なめに、かつ、吹出湯度が
高めになるように制御されて（Ｓ１０）、過剰冷房が防
止されるとともに、騒音の抑制が図られる。On the other hand, if the cumulative value Vd1f' is smaller than the reference value Vc, it is assumed that the amount of activity of the occupant in the room is small, and based on this, the air volume is reduced and the hot water level is increased. (S10), excessive cooling is prevented and noise is suppressed.
なお、上記の実施例では、空気調和装置により冷房を行

行う場合は基本的に冷房時と逆の制御を行うようにすれ

動量が大きければ、それに応じて、風量を少なくしたり
、吹出温度を低くするなどにより暖房を弱めに設定し、
一方、居住者の活動量が小さければ、それに応じて暖房
を強めに設定すれば良い。Note that in the above embodiment, a case has been described in which the air conditioner performs cooling, but when the air conditioner performs heating, the control may basically be performed in the opposite manner to that during cooling. In other words, when heating, if the amount of activity of the occupants in the room is large, the heating is set to be weaker by reducing the air volume or lowering the blowing temperature accordingly.
On the other hand, if the resident's activity level is low, the heating may be set to be stronger accordingly.

を含めることができるものである。In addition, in the above embodiment, in order to simplify the explanation, it is assumed that the air conditioning is controlled only based on the amount of activity of the occupants indoors and the room temperature, but in reality, other factors such as humidity, airflow, etc. conditions can also be taken into account. Furthermore, the objects to be controlled based on these conditions may also include, in addition to the above-mentioned air volume and blowing temperature, the air direction and humidity adjustment by dehumidification or humidification.

る構成である。As described above, the air conditioner according to the present invention includes an infrared detection means for detecting the amount of infrared radiation, a rotation scanning means for rotating the infrared detection means to scan each direction in the room, and an infrared detection means. A control means that reads the detected amount of infrared radiation from each direction in the room at predetermined time intervals to detect the activity state of the occupant, and controls the air conditioning state according to the detected activity state of the occupant. The configuration is equipped with the following.

れるように制御を行うことが可能になる。This utilizes the phenomenon that the amount of infrared radiation from a resident's body is larger than the amount of infrared radiation from the surrounding environment. If a resident is present, the system detects their location, and also detects the resident's activity status based on temporal changes in the resident's location, and controls the air conditioning to provide appropriate air conditioning conditions according to the resident's activity status. It becomes possible to do this.

きる。Therefore, for example, during cooling, if the amount of activity of the occupants in the room being cooled is small, the amount of cooling can be reduced accordingly to prevent excessive cooling and suppress noise; If the amount is large, the amount of cooling can be increased accordingly to obtain a sufficient cooling state. Further, during heating, the control can be performed in the opposite manner to that during cooling.
