(Embodiment 1)
FIG. 1 is a cross-sectional view of an air conditioner according to an embodiment of the present invention, and FIG. 2 is a front view of the air conditioner.

空気調和機10は、その本体内部に、熱交換器1と、送風ファン2と、複数の水受け皿3と、ディフューザー4とを備えている。熱交換器1は、送風ファン2に対し、風の流れの観点で上流側に配置される。水受け皿3は、熱交換器1の下端部の直下に配置される。ディフューザー4は、送風ファン2の下流側の通風路を形成している。   The air conditioner 10 includes a heat exchanger 1, a blower fan 2, a plurality of water trays 3, and a diffuser 4 inside the main body. The heat exchanger 1 is disposed upstream of the blower fan 2 in terms of wind flow. The water receiving tray 3 is disposed immediately below the lower end portion of the heat exchanger 1. The diffuser 4 forms a ventilation path on the downstream side of the blower fan 2.

空気調和機10の本体の前面上部と上面とには吸込口5が形成され、その本体の前面下部から下面にかけて吹出口6が形成される。   A suction port 5 is formed on the front upper surface and the upper surface of the main body of the air conditioner 10, and an air outlet 6 is formed from the lower front surface to the lower surface of the main body.

熱交換器1は吸込口5に対向する位置に配置され、ディフューザー4の下流側端部6aによって囲まれる仮想面が吹出口6を構成する。   The heat exchanger 1 is disposed at a position facing the suction port 5, and an imaginary plane surrounded by the downstream end 6 a of the diffuser 4 constitutes the air outlet 6.

空気調和機10は、前面の吸込口5を開閉するパネル20と、吹出口6を開閉するとともに風向を変更するための上下羽根30とを備えている。上下羽根30の横断面形状は円弧上になっており、上下羽根30の一方面は湾曲凹面になっており、その他方面は湾曲凸面になっている。   The air conditioner 10 includes a panel 20 that opens and closes a suction port 5 on the front surface, and upper and lower blades 30 that open and close the air outlet 6 and change the air direction. The cross-sectional shape of the upper and lower blades 30 is an arc, and one surface of the upper and lower blades 30 is a curved concave surface, and the other surface is a curved convex surface.

パネル駆動機構21は、パネル20の背面側に設けられ、パネル20を開閉する。この開閉に伴い、吸込口5が開閉する。パネル20が吸込口5に最も近接した状態では、吸込口5を閉塞し、パネル20が吸込口5から離間した状態では、パネル20の外周部から吸込口5に空気が流入する。   The panel drive mechanism 21 is provided on the back side of the panel 20 and opens and closes the panel 20. With this opening and closing, the suction port 5 opens and closes. When the panel 20 is closest to the suction port 5, the suction port 5 is closed. When the panel 20 is separated from the suction port 5, air flows from the outer peripheral portion of the panel 20 into the suction port 5.

腕部31は、その一端側を空気調和機10の本体内にて回動自在に保持され、その他端側に上下羽根30を回動自在に保持している。   One end of the arm 31 is rotatably held in the main body of the air conditioner 10, and the upper and lower blades 30 are rotatably held on the other end.

腕部31は、図1に示すように、第1の腕部31aと第2の腕部31bで構成することが好ましい。図示した例では、第1の腕部31aの一端側は空気調和機10の本体内で回動自在に保持されている。第1の腕部31aの他端側は第2の腕部31bの一端側と回動自在に連結されている。そして第2の腕部31bの他端側に、上下羽根30を回動自在に保持している。上下羽根30には、閉塞時に空気調和機10の本体側となる裏面に支持部32が設けられている。この支持部32は、第2の腕部31bに対し回動自在に支持される。   As shown in FIG. 1, the arm part 31 is preferably composed of a first arm part 31a and a second arm part 31b. In the illustrated example, one end side of the first arm portion 31 a is rotatably held in the main body of the air conditioner 10. The other end side of the first arm portion 31a is rotatably connected to one end side of the second arm portion 31b. The upper and lower blades 30 are rotatably held on the other end side of the second arm portion 31b. The upper and lower blades 30 are provided with a support portion 32 on the back surface which is the main body side of the air conditioner 10 when closed. The support portion 32 is rotatably supported with respect to the second arm portion 31b.

腕部31は、空気調和機10の本体の左右両側部に設けられ、それぞれの腕部31は、図示しない連結棒によって連結されている。また、一方の腕部31の側部には腕部用モータが配置されている。腕部用モータの回動は、一方の腕部31だけでなく、連結棒によって他方に配置された腕部31にも伝達される。一方の回転支持部32には羽根用モータが配置され、その回転によって腕部31に対して上下羽根30を回動させる。   The arm portions 31 are provided on the left and right side portions of the main body of the air conditioner 10, and each arm portion 31 is connected by a connecting rod (not shown). In addition, an arm motor is disposed on the side of one arm 31. The rotation of the arm motor is transmitted not only to one arm 31 but also to the arm 31 arranged on the other side by a connecting rod. One rotation support portion 32 is provided with a blade motor, which rotates the upper and lower blades 30 with respect to the arm portion 31.

なお、図示はしないが、空気調和機10は、圧縮機、膨張機、及び室外側熱交換器などを備えた室外ユニットを備えている。また、図2に示すように、空気調和機10のパネル20には、人感センサユニット40と日射センサユニット50とが取り付けられる。人感センサユニット40は、例えば赤外線センサを有しており、この赤外線センサの検出結果から、空調空間(例えば室内)における人の在否を検出する。また、日射センサユニット50は、例えば照度センサを有しており、照度センサの検出結果から空調空間の日射量を測定する。図2に示すように、空気調和機10は、人感センサユニット40及び日射センサユニット50の検出結果に基づき、本空気調和機10の構成各部(例えば圧縮機や送風ファン2)を制御するための制御部60をさらに備えている。この制御部60は、マイコン等により構成され、メモリを用いて空気調和機10の構成各部を制御する。   Although not shown, the air conditioner 10 includes an outdoor unit including a compressor, an expander, an outdoor heat exchanger, and the like. Further, as shown in FIG. 2, a human sensor unit 40 and a solar radiation sensor unit 50 are attached to the panel 20 of the air conditioner 10. The human sensor unit 40 includes, for example, an infrared sensor, and detects the presence or absence of a person in the air-conditioned space (for example, indoors) from the detection result of the infrared sensor. The solar radiation sensor unit 50 includes, for example, an illuminance sensor, and measures the amount of solar radiation in the air-conditioned space from the detection result of the illuminance sensor. As shown in FIG. 2, the air conditioner 10 controls constituent parts of the air conditioner 10 (for example, the compressor and the blower fan 2) based on the detection results of the human sensor unit 40 and the solar radiation sensor unit 50. The control unit 60 is further provided. This control part 60 is comprised by the microcomputer etc., and controls each structure part of the air conditioner 10 using memory.

以上のように構成された空気調和機について、冷房運転時の動作の流れを、図3,図4を用いて説明する。なお、図3、図4は、一連の動作の流れを示しているが、図示の都合上2つの図面に分けている。   About the air conditioner comprised as mentioned above, the flow of operation | movement at the time of air_conditionaing | cooling operation is demonstrated using FIG. 3, FIG. 3 and 4 show a flow of a series of operations, but they are divided into two drawings for convenience of illustration.

SP1において、制御部60は、日射制御ありに設定しているか否かを判断する。Yesの場合、制御部60は図3のSP2に進み、Noの場合、制御部60は、図4のSP10に進む。ここで、日射制御の設定有無は、使用者が例えばリモートコントローラを操作して設定される。   In SP1, the control unit 60 determines whether or not the solar radiation control is set. In the case of Yes, the control unit 60 proceeds to SP2 in FIG. 3, and in the case of No, the control unit 60 proceeds to SP10 in FIG. Here, whether or not the solar radiation control is set is set by a user operating a remote controller, for example.

また、日射制御ありの設定にすると、図2に示される日射センサユニット50によって空調空間への日射が検出された後、カーテンや雨戸によって空調空間への日射が遮蔽されたと判定される。そして、空調空間の温度が設定温度に達すると、日射が検出され室内温度が設定温度に達した時に比べ、図1に示される送風ファン2の回転数が減算される。例えば、900rpmに50rpmを減算した850rpmに送風ファン2の回転数が設定される。この設定では、使用者がカーテンや雨戸によって日射を遮蔽するといった行為を行った際に、使用者の体感温度を損なうことなく、送風ファン2の回転数を減算することが出来、空気調和機を省エネ運転することが出来る。ここで体感温度とは、温度や湿度、輻射、風の強さ、着衣量、人の活動状態によって影響される、暑さ、寒さの感覚を温度で表したものである。つまりこの設定においては、輻射(日射)量が減ったことを検知し、風の強さ(送風ファン2の回転数)を低くすることで体感温度を変化させることなく省エネ運転を実現している。   Further, when the setting is made with the solar radiation control, after the solar radiation sensor unit 50 shown in FIG. 2 detects the solar radiation to the air-conditioned space, it is determined that the solar radiation to the air-conditioned space is shielded by a curtain or a shutter. When the temperature of the air-conditioned space reaches the set temperature, the rotational speed of the blower fan 2 shown in FIG. 1 is subtracted compared to when solar radiation is detected and the room temperature reaches the set temperature. For example, the rotation speed of the blower fan 2 is set to 850 rpm obtained by subtracting 50 rpm from 900 rpm. In this setting, when the user performs an action such as shielding the solar radiation with a curtain or a shutter, the rotational speed of the blower fan 2 can be subtracted without impairing the temperature of the user's experience, Energy saving operation is possible. Here, the sensory temperature represents a sense of heat and cold, which is affected by temperature, humidity, radiation, wind strength, amount of clothes, and human activity, expressed by temperature. In other words, in this setting, it is detected that the amount of radiation (solar radiation) has decreased, and by reducing the wind strength (the rotational speed of the blower fan 2), energy saving operation is realized without changing the sensible temperature. .

一方、日射制御なしの設定にすると、空調空間の温度が設定温度に達した時、室内の日射量にかかわらず、図1に示される送風ファン2の回転数(例えば900rpm)は一定に保たれる。この設定では、使用者が日射を遮蔽した際、風の強さが一定である為、体感温度をより低くすることが可能である。   On the other hand, if the setting without solar radiation control is made, when the temperature of the air-conditioned space reaches the set temperature, the rotational speed (for example, 900 rpm) of the blower fan 2 shown in FIG. 1 is kept constant regardless of the amount of solar radiation in the room. It is. In this setting, when the user shields the solar radiation, the wind intensity is constant, so that the sensible temperature can be lowered.

SP2において、制御部60は、図2に示される日射センサユニット50によって空調空間への日射が検出されたか否かを判断する。Yesと判断した場合、制御部60はSP3に進み、Noと判断した場合、図4のSP10に進む。   In SP2, the control unit 60 determines whether or not the solar radiation to the air-conditioned space is detected by the solar radiation sensor unit 50 shown in FIG. When it is determined Yes, the control unit 60 proceeds to SP3, and when it is determined No, the control unit 60 proceeds to SP10 in FIG.

次に、SP3において、制御部60は、SP2で検出された日射が遮蔽されたか否かを
判断する。Yesと判断すると制御部60はSP4に進み、Noと判断すると、SP10に進む。
Next, in SP3, the control unit 60 determines whether or not the solar radiation detected in SP2 is shielded. If the determination is Yes, the control unit 60 proceeds to SP4, and if the determination is No, the control unit 60 proceeds to SP10.

次に、SP4において、制御部60は、使用者が活動量判定ありに設定しているか否かを判断する。Yesと判断した場合、制御部60はSP5に進み、Noと判断した場合SP8に進む。ここで、活動量判定の設定有無は、使用者が例えばリモートコントローラを操作することで設定される。   Next, in SP4, the control unit 60 determines whether or not the user has set the activity amount determination. When it is determined Yes, the control unit 60 proceeds to SP5, and when it is determined No, the control unit 60 proceeds to SP8. Here, whether or not the activity amount determination is set is set by the user operating the remote controller, for example.

また、活動量判定ありに設定すると、室内温度が設定温度に達した時、図2に示される人感センサユニット40によって判定された室内に居る人の活動量に応じて、図1に示される送風ファン2の回転数が決定される(例えば活動量が0.5metの時800rpm、活動量が1metの時900rpm)。この設定では、使用者があまり活動していない(例えば横になってテレビを観賞している)時、送風ファン2の回転数を減算することが出来、空気調和機を省エネ運転することが出来る。つまりこの設定においては、ひとの活動状態(活動量)を判定し、風の強さ(送風ファン2の回転数)を低くすることで体感温度を変化させることなく省エネ運転を実現している。   Also, when the activity amount determination is set, when the room temperature reaches the set temperature, it is shown in FIG. 1 according to the activity amount of the person in the room determined by the human sensor unit 40 shown in FIG. The number of rotations of the blower fan 2 is determined (for example, 800 rpm when the activity amount is 0.5 met and 900 rpm when the activity amount is 1 met). With this setting, when the user is not very active (for example, lying down and watching TV), the rotation speed of the blower fan 2 can be subtracted, and the air conditioner can be operated in an energy-saving manner. . In other words, in this setting, the person's activity state (activity amount) is determined, and by reducing the wind strength (the rotational speed of the blower fan 2), energy-saving operation is realized without changing the sensible temperature.

また、活動量判定なしに設定すると、室内温度が設定温度に達した時、室内に居る人の活動量にかかわらず図1に示される送風ファン2の回転数は一定(例えば900rpm)に保たれる。   Moreover, when setting without activity amount determination, when the room temperature reaches the set temperature, the rotation speed of the blower fan 2 shown in FIG. 1 is kept constant (for example, 900 rpm) regardless of the amount of activity of people in the room. It is.

SP5において、制御部60は、図2に示される人感センサユニット40による活動量の検知結果によって、活動量を判定する。この後、制御部60はSP6に進む。   In SP5, the control unit 60 determines the activity amount based on the detection result of the activity amount by the human sensor unit 40 shown in FIG. Thereafter, the control unit 60 proceeds to SP6.

SP6において、制御部60は、空調空間の温度が使用者の意図する設定温度に達しているかを判定する。その後、制御部60は、SP7に進み、室内温度、日射量および室内に居る人の活動量に応じた送風ファン2の回転数を決定する(例えば室内温度が設定温度に達し活動量が0.5metの時800rpm)。その後、制御部60はSP16に進む。このとき、SP5において、活動量が最も低いと判定されていた場合、最も省エネ運転が可能となる。   In SP6, the control unit 60 determines whether the temperature of the air-conditioned space has reached the set temperature intended by the user. Thereafter, the control unit 60 proceeds to SP7, and determines the rotational speed of the blower fan 2 according to the room temperature, the amount of solar radiation, and the amount of activity of people in the room (for example, the room temperature reaches the set temperature and the amount of activity is 0. 0). 800 rpm for 5 metres). Thereafter, the control unit 60 proceeds to SP16. At this time, when it is determined in SP5 that the amount of activity is the lowest, the most energy-saving operation is possible.

SP4でNoと判断すると、制御部60は、SP8において、SP6と同様にして空調空間の温度が設定温度に達しているかを判定する。その後、制御部60はSP9に進み、室内温度および日射量に応じた送風ファン2の回転数を決定し(例えば室内温度が設定温度に達した時850rpm)、SP16に進む。   If it is determined No in SP4, the controller 60 determines in SP8 whether the temperature of the air-conditioned space has reached the set temperature in the same manner as SP6. Thereafter, the control unit 60 proceeds to SP9, determines the rotational speed of the blower fan 2 according to the room temperature and the amount of solar radiation (for example, 850 rpm when the room temperature reaches the set temperature), and proceeds to SP16.

SP1、SP2およびSP3から進んだSP10(図4参照)において、制御部60は、SP4と同様にして活動量判定の有無を判定し、「有り」と判定するとSP11に進み、「無し」と判定するとSP14に進む。   In SP10 advanced from SP1, SP2 and SP3 (see FIG. 4), the control unit 60 determines the presence / absence of activity amount determination in the same manner as SP4, and proceeds to SP11 when determined to be “present” and determined to be “not present”. Then, it progresses to SP14.

SP11において、制御部60は、図2に示される人感センサユニット40による活動量の検知結果によって、活動量を判定しSP12に進む。SP12において、室内温度が使用者の意図する設定温度に達しているかを判定した後、SP13に進み、室内温度、日射量および室内に居る人の活動量に応じた送風ファン2の回転数を決定し(例えば室内温度が設定温度に達し活動量が0.5metの時850rpm)、SP17に進む。   In SP11, the control unit 60 determines the activity amount based on the activity amount detection result by the human sensor unit 40 shown in FIG. 2, and proceeds to SP12. In SP12, after determining whether the room temperature has reached the set temperature intended by the user, the process proceeds to SP13, and the rotation speed of the blower fan 2 is determined in accordance with the room temperature, the amount of solar radiation, and the amount of activity of the person in the room. (For example, when the room temperature reaches the set temperature and the activity amount is 0.5 met, 850 rpm), the process proceeds to SP17.

SP10から進んだSP14において、制御部60は、空調空間の温度が使用者の意図する設定温度に達しているかを判定した後、SP15に進み、空調空間の温度および日射量に応じた送風ファン2の回転数を決定し(例えば室内温度が設定温度に達した時950rpm)、SP17に進む。   In SP14 advanced from SP10, the control unit 60 determines whether or not the temperature of the air-conditioned space has reached the set temperature intended by the user, and then proceeds to SP15 and the blower fan 2 according to the temperature of the air-conditioned space and the amount of solar radiation. (For example, 950 rpm when the room temperature reaches the set temperature), the program proceeds to SP17.
