Description

【０００１】
【発明の属する技術分野】
本発明は、吹出口に設けた縦羽根の振り角度に応じて吹出風量を制御する空気調和機に関する。
【０００２】
【従来の技術】
従来、空気調和機は、吹出口に左右方向の風向を調節する縦羽根を設け、この縦羽根の振り角度をステッピングモータ等の縦羽根駆動用モータで制御することにより、吹出口から吹き出される左右方向の風向きを調節するようにしたものがある。
【０００３】
この種の空気調和機は、冷房・除湿運転時、湿度の高い状態で縦羽根を左右に大きく曲げて長時間運転すると、室内の温度や湿度の条件によっては吹出口付近に露が付着し床に滴下する恐れがあることから、冷房・除湿運転時には、縦羽根の振り角が大きくならないように制御し、これにより、冷房・除湿運転時の露付きを防止している。なお、暖房運転時においては、冷房・除湿運転時よりも振り角度が大きくなるように制御されている。
【０００４】
【発明が解決しようとする課題】
ところで、上記従来の空気調和機において、縦羽根の振り角度を小さくしていると、空気調和機から吹き出される調和空気が左右方向に届きにくいので、空気調和機の左右方向の領域を冷房・除湿する場合には、時間がかかり、また、部屋全体を冷房・除湿する場合にも、部屋の温度分布にムラができやすいという問題があった。そのため、冷房・除湿運転時の露付きを抑え、かつ、縦羽根の振り角度を大きくして運転できるような制御が求められていた。
【０００５】
本発明は、冷房・除湿運転時の露付きを抑えるとともに、縦羽根の振り角度を大きくして左右方向への吹き出し角度を大きくする空気調和機を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、請求項１記載の発明は、送風機と、この送風機から吹き出す空気の吹出口と、この吹出口に揺動自在に設けられた複数の縦羽根と、これら複数の縦羽根を同時に揺動する連動板及び縦羽根駆動用モータを有し、複数の縦羽根を左右にスイングさせる揺動制御手段とを備えた空気調和機において、 前記揺動制御手段の縦羽根駆動用モータの回転位置を検出することにより縦羽根の振り角度を検出する位置検出手段と、この位置検出手段に基づいて送風機のファン回転数を制御する回転数制御手段とを設け、前記回転数制御手段は、縦羽根の振り角度が所定角度より大きいとき、ファン回転数を所定回転数以下に制限することを特徴とする空気調和機。
【０００８】
請求項２に記載の発明は、前記揺動制御手段は縦羽根を任意の振り角度位置に停止可能であることを特徴とする請求項１に記載の空気調和機。
【０００９】
【発明の実施の形態】
以下、本発明の一実施形態を図１〜図６に基づいて説明する。図１は本発明の一実施形態における空気調和機である。
【００１０】
図１において、１は空気調和機であり、室内機２、室外機３、配管４、及びワイヤレスリモコン（以下、単にリモコンという）５等から構成される。この空気調和機１は、リモコン５によって操作することができ、リモコン操作することによって室内の暖房・冷房・除湿運転をすることができる。
【００１１】
図２は室内機の正面図、図３は室内機の側断面図、図４は縦羽根の平面図である。図において、室内機２はケーシング６の前面に吸込口７が形成され、ケーシング６内に収容された熱交換器８と送風機１２とを通して吸込口７から吹出口１３へと通風路１４が形成されている。吹出口１３付近の内部には風向調節装置１５があり、この風向調節装置１５の縦羽根１６を枢支する取付枠１７が斜め下方に開口して取り付けられている。取付枠１７には、図４に示すように、複数の回動孔１８が等間隔に設けられ、複数の縦羽根１６が回動軸１９を介して揺動自在に枢着されている。縦羽根１６には、連動軸２１を介して連動板２２が取り付けられ、１つの縦羽根１６を揺動することにより同時に全部の縦羽根１６を揺動することができ、縦羽根１６の揺動によって吹出風を左右方向に向きを変えることができる。右端の縦羽根１６の回動軸１９には、ステッピングモータ２６の回転軸が取り付けられ、縦羽根１６を回動自在に駆動できる。ステッピングモータ２６は制御装置（図示せず）に接続されている。縦羽根１６の下流側には、図３に示すように、水平羽根２３が取り付けられ、吹出風の向きを上下方向に調節できる。
【００１２】
空気調和機１を運転すると送風機１２の回転によって吸込口７を通して吸い込まれた室内空気が熱交換器８で加熱または冷却されて通風路１４を通って吹出口１３へ送られる。縦羽根１６によって左右方向の吹出風が、水平羽根２３によって上下方向の吹出風が調節され、室内に吹き出される。
【００１３】
図５は縦羽根の振り角度と風量との制御を示すブロック図である。５はリモコン、２４はマイクロコンピュータ（以下、マイコンという）２５を有する制御装置、２６は縦羽根駆動用のステッピングモータ、２７は送風機１２のファンモータである。
【００１４】
リモコン５には、空気調和機１を運転あるいは停止させる運転・停止スイッチ３０、冷房、暖房等の運転モードを設定する運転モードスイッチ３１、室内を希望の温度に設定する設定温度スイッチ３２、縦羽根１６をスイング（左右に揺動）させあるいはスイングを停止させるスイングスイッチ３３、及び風量を強・中・弱に設定する風量切替スイッチ３４等が設けられている。スイングスイッチ３３を操作することにより縦羽根１６をスイングさせることができ、スイングさせた後、もう一度スイングスイッチ３３を操作することにより、縦羽根１６を任意の振り角度位置に停止させることができる。縦羽根１６は、例えば、縦羽根１６を前方に垂直になるような状態を０°として左右にそれぞれ６０°の間でスイングするように制御されている。そして、縦羽根１６の停止位置もこの範囲内の任意の位置に停止することができる。
【００１５】
マイコン２５には、縦羽根１６がスイングするようにステッピングモータ２６をステップ数で制御する縦羽根の揺動制御手段（以下、単に揺動手段という）３５と、この揺動手段３５のステップ数から縦羽根１６の振り角度を検出する縦羽根の位置検出手段３６と、ファンモータ２７の回転数を制御する回転数制御手段３７とを備えている。
【００１６】
揺動手段３５は、冷房・除湿運転時にリモコン５からの縦羽根１６のスイングの指令があると、ステッピングモータ２６を回転させることにより縦羽根１６をスイングさせ、吹出口１３から吹き出される風の向きを変化させる。揺動手段３５は、ステッピングモータ２６をステップ数（例えば、縦羽根の振り角度に応じて左右それぞれ３０ステップ）で制御し、縦羽根をスイングさせている。
【００１７】
位置検出手段３６は、揺動手段３５のステップ数の信号を検出することにより、縦羽根１６の振り角度位置を検出することができる。
【００１８】
回転数制御手段３７は、暖房運転時には露付きの恐れがないため、破線矢印に示すように、リモコン５で設定された風量に基づいて、ファンモータ２７が回転する。冷房・除湿運転時には、縦羽根１６の振り角度の大きい状態（縦羽根１６を振り角度の大きい位置に停止して使用する場合と縦羽根１６をスイングして使用する場合）で、かつ、風量の多い状態で使用していると、吹出口１３付近に露付きを生じる恐れがあるため、縦羽根１６の振り角度に応じて風量（ファン回転数）に制限を設け、露付きを生じないように制御している。縦羽根１６の振り角度が小さいときには、風量（ファン回転数）に制限を設けず、振り角度が大きくなると、最大風量（ファンの最大回転数）を抑えるような制御を設ける。
【００１９】
図６は冷房・除湿運転時の縦羽根の振り角度と風量（ファンの回転数）制御の関係の一例を示している。位置検出手段３６により検出された縦羽根１６の振り角度が３０°未満の場合、最大風量に制限を設けないので、風量はリモコン５で設定された強・中・弱いずれの風量での吹き出しが可能である。縦羽根１６の振り角度が３０°以上４５°未満の場合、回転数制御手段３７は最大風量が中以下になるようにファン回転数を制御する。これにより、リモコン５での風量が強に設定されても、風量は中以下に抑えられ、中または弱の吹き出しが可能である。縦羽根１６の振り角度が４５°以上６０°未満の場合、回転数制御手段３７は最大風量が弱以下になるようにファン回転数を制御する。これにより、リモコン５での風量が強あるいは中に設定されても、風量は弱に抑えられ、弱のみの吹き出しが可能である。
【００２０】
以上のように、縦羽根１６の振り角度に応じて縦羽根１６の振り角度が小さい位置では、風量（ファン回転数）に制限を設けず、振り角度の大きい位置では最大風量（ファンの最大回転数）に制限を設けているので、振り角度の大きい露付きの発生しやすい位置では吹出口１３から吹き出される風量を低く抑え、露付きの発生を抑えるようにする。なお、風量を強に設定してスイング運転する場合には、縦羽根１６の移動とともに、風量が強と弱とを繰り返して変化し、吹き出される。
【００２１】
このように、縦羽根１６の振り角度が大きい位置では風量を低く抑えて露付きを生じにくくしているので、縦羽根１６の振り角度を大きくすることができ、吹出口１３の左右方向の吹出角度範囲を大きくすることができる。
【００２２】
以上、一実施形態に基づいて本発明を説明したが、本発明はこれに限定されるものではない。
【００２３】
本実施形態において、縦羽根１６の振り角度の境界線を設け、この境界線を境に送風機１２の最大風量を段階的に変化させているが、境界線を設けず、縦羽根１６の振り角度に比例するように最大風量に制限を設けるようにしても良い。
【００２４】
【発明の効果】
以上説明したように、本発明の空気調和機は、送風機と、この送風機から吹き出す空気の吹出口と、この吹出口に揺動自在に設けられた複数の縦羽根と、これら複数の縦羽根を同時に揺動する連動板及び縦羽根駆動用モータを有し複数の縦羽根を左右にスイングさせる揺動制御手段とを備え、この揺動制御手段から縦羽根の振り角度を検出する縦羽根の位置検出手段と、この位置検出手段に基づいて送風機のファンの回転数を制御する回転数制御手段とを設け、吹出口に設けた縦羽根の振り角度の大きい位置では風量を小さく抑えているので、吹出口付近での露付きを抑え、吹出方向の範囲を大きくすることができる。これにより、部屋の空調されにくい領域を小さくすることができ、また、部屋全体の温度分布を良くすることができる。

[0008]
The invention according to claim 2 is the air conditioner according to claim 1 , wherein the swing control means can stop the vertical blade at an arbitrary swing angle position.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows an air conditioner according to an embodiment of the present invention.
[0010]
In FIG. 1, reference numeral 1 denotes an air conditioner, which includes an indoor unit 2, an outdoor unit 3, a pipe 4, a wireless remote controller (hereinafter simply referred to as a remote controller) 5, and the like. The air conditioner 1 can be operated by the remote controller 5, and the room can be heated, cooled and dehumidified by operating the remote controller.
[0011]
2 is a front view of the indoor unit, FIG. 3 is a side sectional view of the indoor unit, and FIG. 4 is a plan view of the vertical blade. In the figure, the indoor unit 2 has a suction port 7 formed in the front surface of the casing 6, and a ventilation path 14 is formed from the suction port 7 to the blower outlet 13 through the heat exchanger 8 and the blower 12 accommodated in the casing 6. ing. A wind direction adjusting device 15 is provided in the vicinity of the air outlet 13, and a mounting frame 17 that pivotally supports the vertical blades 16 of the wind direction adjusting device 15 is attached so as to open obliquely downward. As shown in FIG. 4, a plurality of rotation holes 18 are provided at equal intervals in the mounting frame 17, and a plurality of vertical blades 16 are pivotally attached via a rotation shaft 19. An interlocking plate 22 is attached to the vertical blades 16 via an interlocking shaft 21, and by swinging one vertical blade 16, all the vertical blades 16 can be swung simultaneously. The direction of the blowing wind can be changed in the left-right direction. The rotation shaft 19 of the stepping motor 26 is attached to the rotation shaft 19 of the rightmost vertical blade 16 so that the vertical blade 16 can be driven to rotate freely. The stepping motor 26 is connected to a control device (not shown). As shown in FIG. 3, a horizontal blade 23 is attached to the downstream side of the vertical blade 16, and the direction of the blowing air can be adjusted in the vertical direction.
[0012]
When the air conditioner 1 is operated, the room air sucked through the suction port 7 by the rotation of the blower 12 is heated or cooled by the heat exchanger 8 and sent to the outlet 13 through the ventilation path 14. The vertical blowing air is adjusted by the vertical blades 16 and the vertical blowing air is adjusted by the horizontal blades 23 and blown into the room.
[0013]
FIG. 5 is a block diagram showing the control of the swing angle of the vertical blades and the air volume. 5 is a remote controller, 24 is a control device having a microcomputer (hereinafter referred to as a microcomputer) 25, 26 is a stepping motor for driving vertical blades, and 27 is a fan motor of the blower 12.
[0014]
The remote controller 5 includes an operation / stop switch 30 for operating or stopping the air conditioner 1, an operation mode switch 31 for setting an operation mode such as cooling or heating, a set temperature switch 32 for setting a desired temperature in the room, a vertical blade There are provided a swing switch 33 for swinging 16 (to swing left and right) or stopping the swing, an air volume changeover switch 34 for setting the air volume to strong, medium and weak. By operating the swing switch 33, the vertical blade 16 can be swung, and after the swing, the vertical blade 16 can be stopped at an arbitrary swing angle position by operating the swing switch 33 again. The vertical blades 16 are controlled so as to swing between 60 ° to the left and right, for example, with the vertical blade 16 being perpendicular to the front as 0 °. And the stop position of the vertical blade | wing 16 can also be stopped in the arbitrary positions within this range.
[0015]
The microcomputer 25 includes a vertical blade swing control means (hereinafter simply referred to as swing means) 35 for controlling the stepping motor 26 by the number of steps so that the vertical blade 16 swings, and the number of steps of the swing means 35. Vertical blade position detecting means 36 for detecting the swing angle of the vertical blade 16 and rotational speed control means 37 for controlling the rotational speed of the fan motor 27 are provided.
[0016]
When the swinging means 35 is instructed to swing the vertical blade 16 from the remote controller 5 during the cooling / dehumidifying operation, the swinging means 35 swings the vertical blade 16 by rotating the stepping motor 26, and the wind blown from the outlet 13 Change direction. The swinging means 35 controls the stepping motor 26 by the number of steps (for example, 30 steps on the left and right according to the swing angle of the vertical blades) to swing the vertical blades.
[0017]
The position detection means 36 can detect the swing angle position of the vertical blade 16 by detecting the signal of the number of steps of the swing means 35.
[0018]
Since there is no risk of dew condensation during the heating operation of the rotation speed control means 37, the fan motor 27 rotates based on the air volume set by the remote controller 5 as indicated by the broken line arrow. During the cooling / dehumidifying operation, the swinging angle of the vertical blade 16 is large (when the vertical blade 16 is stopped and used at a position where the swinging angle is large and when the vertical blade 16 is swung and used) and If it is used in a large state, there is a risk of dew condensation in the vicinity of the air outlet 13, so a restriction is imposed on the air volume (fan speed) according to the swing angle of the vertical blades 16 so that dew condensation does not occur. I have control. When the swing angle of the vertical blades 16 is small, there is no restriction on the air volume (fan rotation speed), and control is performed to suppress the maximum air volume (fan maximum rotation speed) when the swing angle is large.
[0019]
FIG. 6 shows an example of the relationship between the swing angle of the vertical blades and the air volume (fan rotation speed) control during the cooling / dehumidifying operation. When the swing angle of the vertical blade 16 detected by the position detection means 36 is less than 30 °, there is no restriction on the maximum air volume, so that the air volume is blown out in any of the strong, medium and weak air volumes set by the remote controller 5. Is possible. When the swing angle of the vertical blades 16 is not less than 30 ° and less than 45 °, the rotation speed control means 37 controls the fan rotation speed so that the maximum air volume is not more than medium. Thereby, even if the air volume at the remote controller 5 is set to be strong, the air volume is suppressed to a medium or lower level, and a medium or weak blowout is possible. When the swing angle of the vertical blade 16 is not less than 45 ° and less than 60 °, the rotation speed control means 37 controls the fan rotation speed so that the maximum air volume becomes less than or equal to weak. Thereby, even if the air volume at the remote controller 5 is set to be strong or medium, the air volume is suppressed to be weak and only a weak blow is possible.
[0020]
As described above, there is no restriction on the air volume (fan speed) at a position where the swing angle of the vertical blade 16 is small according to the swing angle of the vertical blade 16, and the maximum air volume (maximum fan rotation) at a position where the swing angle is large. Therefore, the amount of air blown out from the air outlet 13 is kept low at a position where dew is likely to occur with a large swing angle, so that dew generation is suppressed. In the case of swing operation with the air volume set to be strong, the air volume is repeatedly changed between strong and weak as the vertical blades 16 are moved, and blown out.
[0021]
In this way, at the position where the swing angle of the vertical blade 16 is large, the air volume is kept low to make it difficult to cause dew, so the swing angle of the vertical blade 16 can be increased, and the blowout of the air outlet 13 in the left-right direction The angle range can be increased.
[0022]
As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this.
[0023]
In this embodiment, a boundary line of the swing angle of the vertical blade 16 is provided, and the maximum air volume of the blower 12 is changed stepwise from the boundary line, but the swing angle of the vertical blade 16 is not provided with the boundary line. The maximum air volume may be limited so as to be proportional to
[0024]
【The invention's effect】
As described above, the air conditioner of the present invention includes a blower, a blowout port for air blown out from the blower, a plurality of vertical blades swingably provided at the blowout port, and the plurality of vertical blades. A position of the vertical blade that detects the swing angle of the vertical blade from the swing control means, and includes an interlocking plate that swings simultaneously and a swing control means that swings a plurality of vertical blades to the left and right. Since the detection means and the rotation speed control means for controlling the rotation speed of the fan of the blower based on this position detection means are provided, the air volume is kept small at a position where the swing angle of the vertical blade provided at the blowout port is large. It is possible to suppress dew condensation in the vicinity of the outlet and increase the range of the outlet direction. Thereby, the area | region where it is hard to air-condition a room can be made small, and the temperature distribution of the whole room can be improved.
