Description

本発明は、空気調和装置に関するものである。   The present invention relates to an air conditioner.

空気調和装置には送風機が内蔵され、送風機によって室内への送風が行われる。一般に送風機の回転数を大きくするほど風量が上昇するが、送風機から発生する騒音も大きくなる。   The air conditioner has a built-in blower, and air is blown into the room by the blower. Generally, the air volume increases as the rotational speed of the blower increases, but the noise generated from the blower also increases.

下記の特許文献１では、フラップの長手方向における両端部において、送風される空気の乱れが著しく、騒音が発生するため、送風フラップの案内表面に多数の溝を形成することが記載されている。   In the following Patent Document 1, it is described that a large number of grooves are formed on the guide surface of the blown flap because the disturbance of the blown air is significant and noise is generated at both ends in the longitudinal direction of the flap.

また、下記の特許文献２では、横羽根の吐出風の当たる面に複数の整流板を設けた技術が開示されている。これにより、空気調和機の長手方向において吸込み口や熱交換器の不均一又はファンの形状の不均一があることを原因として、吐出風の一部が横走りして乱流が起こるのを防止する。   Moreover, in the following Patent Document 2, a technique is disclosed in which a plurality of rectifying plates are provided on the surface of the horizontal blade that the discharge air strikes. This prevents a part of the discharge air from running sideways and causing turbulence due to non-uniform inlets and heat exchangers or non-uniform fan shapes in the longitudinal direction of the air conditioner. To do.

さらに、下記の特許文献３では、空気の吹出し側の流路において、クロスフローファンに対して角度をつけて整流板が設けられた技術が開示されている。これにより、ファンプレートの近傍での風の乱れで発生する騒音を低減する。   Further, Patent Document 3 below discloses a technique in which a rectifying plate is provided at an angle with respect to the cross flow fan in a flow path on the air blowing side. Thereby, the noise generated by the turbulence in the vicinity of the fan plate is reduced.

上記特許文献１から３では、吹出し空気が流通又当たる部位において生じる騒音を低減することを目的として細長い溝や整流板を設けている。一方、空気調和装置で発生する騒音には、上述したとおり、送風機に起因するものがあるため、吹出し口からの風量を維持又は上昇させつつ、送風機から発生する騒音を低減できることが望ましい。   In Patent Documents 1 to 3, an elongated groove and a rectifying plate are provided for the purpose of reducing noise generated in a portion where the blown air flows or hits. On the other hand, since the noise generated in the air conditioner is attributed to the blower as described above, it is desirable that the noise generated from the blower can be reduced while maintaining or increasing the air volume from the outlet.

本発明は、このような事情に鑑みてなされたものであって、吹出し口からの風量を維持又は上昇させつつ、送風機から発生する騒音を低減することが可能な空気調和装置を提供することを目的とする。   This invention is made in view of such a situation, Comprising: It is providing the air conditioning apparatus which can reduce the noise which generate | occur | produces from an air blower, maintaining or raising the air volume from a blower outlet. Objective.

上記課題を解決するために、本発明の空気調和装置は以下の手段を採用する。
すなわち、本発明に係る空気調和装置は、吹出し口と、前記吹出し口に設置され、吹き出される空気の流れ方向を変更可能な風向調整板とを備え、前記風向調整板の表面において、前記空気の流れ方向に沿って細長い流線型形状を有する突起部が形成されている。 In order to solve the above problems, the air conditioning apparatus of the present invention employs the following means.
That is, the air conditioning apparatus according to the present invention includes a blowout port and a wind direction adjusting plate that is installed at the blowout port and is capable of changing a flow direction of the blown air, and on the surface of the wind direction adjusting plate, the air A projection having an elongated streamline shape is formed along the flow direction.

この構成によれば、吹出し口に設置された風向調整板は、吹き出される空気の流れ方向を変更できる板材であり、風向調整板の表面には、空気の流れ方向に沿って細長い流線型形状を有する突起部が形成されている。これにより、吹出し口から吹き出される空気が、風向調整板に沿って流れた結果、突起部は、突起部の下流側における風向調整板の表面に常時乱流を発生させる。そして、突起部は、境界層剥離を抑制して、乱流化された境界層を維持するため、風向調整板の表面において、空気の流れの剥離が遅れ、空気抵抗が減少する。   According to this configuration, the airflow direction adjusting plate installed at the outlet is a plate material that can change the flow direction of the blown air, and the surface of the airflow direction adjusting plate has an elongated streamline shape along the air flow direction. The protrusion part which has is formed. Thereby, as a result of the air blown from the outlet opening flowing along the wind direction adjusting plate, the protrusions always generate turbulence on the surface of the air direction adjusting plate on the downstream side of the protrusions. And since a projection part suppresses boundary layer peeling and maintains the turbulent boundary layer, on the surface of a wind direction adjusting plate, separation of the air flow is delayed and air resistance decreases.

したがって、風向調整板に沿って空気が流れやすくなり、突起部が形成されていない風量調整板と比べて、風向調整板に沿って流れる風量を増加させることができる。よって、従来と比べて送風機の回転数を同一としても風量を上げることができ、送風機を要因とする騒音を低減できる。   Therefore, air easily flows along the wind direction adjusting plate, and the amount of air flowing along the wind direction adjusting plate can be increased as compared with the air amount adjusting plate in which no protrusion is formed. Therefore, the air volume can be increased even when the rotation speed of the blower is the same as in the conventional case, and noise caused by the blower can be reduced.

また、風向調整板の表面において空気抵抗が減少することから、吹出し口外部の空気を巻き込みにくくなる。その結果、冷房運転時において湿度の高い空気が吹出し口に接触しなくなり、吹出し口で発生する結露を抑制できる。   Moreover, since air resistance decreases on the surface of the wind direction adjusting plate, it becomes difficult to entrain air outside the outlet. As a result, high-humidity air does not come into contact with the air outlet during the cooling operation, and condensation generated at the air outlet can be suppressed.

本発明に係る空気調和装置は、吹出し口と、前記吹出し口に設置され、吹き出される空気の流れ方向を変更可能な風向調整板とを備え、前記風向調整板の表面において、下流側に常時乱流を発生させ、境界層剥離を抑制する突起部が形成されている。   An air conditioner according to the present invention includes a blowout port and a wind direction adjusting plate that is installed at the blowout port and can change the flow direction of the blown air, and is always on the downstream side of the surface of the wind direction adjusting plate. Protrusions that generate turbulent flow and suppress boundary layer separation are formed.

上記発明において、前記突起部は、前記空気の流れ方向に対して垂直方向に複数配置されてもよい。   In the above invention, a plurality of the protrusions may be arranged in a direction perpendicular to the air flow direction.

この構成によれば、風向調整板が空気の流れ方向に対して垂直方向に長い長尺状板材であるときにも、風向調整板の長手方向のほぼすべての領域にわたって空気抵抗を減少させることができる。   According to this configuration, even when the wind direction adjusting plate is a long plate material that is long in the direction perpendicular to the air flow direction, the air resistance can be reduced over almost the entire region in the longitudinal direction of the wind direction adjusting plate. it can.

上記発明において、前記突起部は、前記風向調整板の一面側のみに形成されてもよい。   In the above invention, the protrusion may be formed only on one side of the wind direction adjusting plate.

この構成によれば、風向調整板の一面側のみに突起部が形成され、突起部が形成された風向調整板の一面に当たったほうの空気の風量がより増加する。空気の風量を増加させたいほうに突起部が設けられればよい。   According to this configuration, the protrusion is formed only on one surface side of the wind direction adjusting plate, and the air volume of the air hitting the one surface of the air direction adjusting plate on which the protrusion is formed is further increased. The protrusion may be provided on the side where it is desired to increase the air volume.

本発明によれば、吹出し口からの風量を維持又は上昇させつつ、送風機から発生する騒音を低減することができる。   ADVANTAGE OF THE INVENTION According to this invention, the noise which generate | occur | produces from an air blower can be reduced, maintaining or raising the air volume from a blower outlet.

以下に、本発明に係る実施形態について、図面を参照して説明する。
本発明の一実施形態に係る空気調和装置の室内機１は、図１及び図２に示すように、筐体２と、筐体２に内蔵された送風機（図示せず。）及び熱交換器（図示せず。）などを備える。また、室内機１の筐体２には、外部空気を筐体２内へ取り込む吸込み口３と、熱交換後の空気を筐体２内から外部へ吹き出す吹出し口４が形成される。 Embodiments according to the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 and 2, an indoor unit 1 of an air conditioner according to an embodiment of the present invention includes a housing 2, a blower (not shown) built in the housing 2, and a heat exchanger. (Not shown). Further, the housing 2 of the indoor unit 1 is formed with a suction port 3 for taking outside air into the housing 2 and a blowout port 4 for blowing the air after heat exchange from the inside of the housing 2 to the outside.

外部空気は、送風機によって、吸込み口３を介して、筐体２内へ取り込まれる。送風機によって取り込まれた空気は、熱交換器を通過するとき、熱交換器内を流れる冷媒と熱交換される。冷房運転時、空気は冷媒によって冷却され、暖房運転時、空気は冷媒によって加熱される。熱交換器を通過した空気は、吹出し口４を介して、筐体２内から外部へ吹き出される。   External air is taken into the housing 2 via the suction port 3 by a blower. When the air taken in by the blower passes through the heat exchanger, it exchanges heat with the refrigerant flowing in the heat exchanger. During the cooling operation, air is cooled by the refrigerant, and during the heating operation, air is heated by the refrigerant. The air that has passed through the heat exchanger is blown out from the inside of the housing 2 through the blowout port 4.

吹出し口４には、吹き出される空気の流れを変更するフラップ５及びルーバ６が設置される。フラップ５及びルーバ６は、いずれも風向調整板の一例である。   A flap 5 and a louver 6 are installed at the outlet 4 to change the flow of air to be blown out. The flap 5 and the louver 6 are both examples of a wind direction adjusting plate.

フラップ５は、長尺状の板状部材であり、吹出し口４において長手方向が水平方向に対して平行となるように設置される。フラップ５は、フラップ５の長手方向に対して平行な軸を中心にして回動する。これにより、フラップ５は、吹出し口４から吹き出される空気の風向を上下方向に調整できる。   The flap 5 is a long plate-like member, and is installed so that the longitudinal direction is parallel to the horizontal direction at the outlet 4. The flap 5 rotates around an axis parallel to the longitudinal direction of the flap 5. Thereby, the flap 5 can adjust the wind direction of the air which blows off from the blower outlet 4 to an up-down direction.

ルーバ６は、長尺状の板状部材であり、吹出し口４において長手方向が鉛直方向に対して平行となるように設置される。ルーバ６は、ルーバ６の長手方向に対して平行な軸を中心にして回動する。これにより、ルーバ６は、吹出し口４から吹き出される空気の風向を左右方向に調整できる。   The louver 6 is a long plate-like member, and is installed so that the longitudinal direction thereof is parallel to the vertical direction at the outlet 4. The louver 6 rotates around an axis parallel to the longitudinal direction of the louver 6. Thereby, the louver 6 can adjust the wind direction of the air blown out from the blowout port 4 in the left-right direction.

なお、吹出し口４には、フラップ５とルーバ６のいずれか一方のみ設置されてもよい。   Note that only one of the flap 5 and the louver 6 may be installed in the outlet 4.

フラップ５とルーバ６の表面には、図３から図５に示すように、細長い流線型形状を有する突起部７が形成される。なお、図１及び図２では、フラップ５とルーバ６の表面における突起部７を省略して示している。
以下では、ルーバ６の表面に突起部７が形成される場合について説明する。フラップ５の表面に形成される突起部７も同一の構成及び作用効果を奏する。 As shown in FIGS. 3 to 5, a protrusion 7 having an elongated streamline shape is formed on the surfaces of the flap 5 and the louver 6. In FIGS. 1 and 2, the protrusions 7 on the surfaces of the flap 5 and the louver 6 are omitted.
Below, the case where the projection part 7 is formed in the surface of the louver 6 is demonstrated. The protrusion 7 formed on the surface of the flap 5 also has the same configuration and operational effects.

突起部７は、吹出し口４から吹き出される空気の流れ方向に沿って細長い流線型形状を有し、ルーバ６の平滑な板面から凸状に突起している。突起部７は、空気の流れ方向の上流側に位置する先端が半球形状を有し、下流側に位置する後端が尖った形状を有する。すなわち、突起部７は、先端から後端に向かって徐々に幅及び高さが大きくなり、中間あたりで、幅及び高さが最大となり、中間から後端にかけて徐々に幅及び高さが小さくなるように形成される。   The protrusion 7 has a slender streamline shape along the flow direction of the air blown from the blowout port 4, and protrudes in a convex shape from the smooth plate surface of the louver 6. The protrusion 7 has a hemispherical tip located on the upstream side in the air flow direction and a pointed rear end located on the downstream side. That is, the protrusion 7 gradually increases in width and height from the front end toward the rear end, reaches the maximum width and height around the middle, and gradually decreases in width and height from the middle to the rear end. Formed as follows.

突起部７の長さは、ルーバ６の短手方向の幅に比べて短く、突起部７は、ルーバ６の短手方向の幅内に一つのみ配置される。   The length of the protrusion 7 is shorter than the width of the louver 6 in the short direction, and only one protrusion 7 is disposed within the width of the louver 6 in the short direction.

突起部７は、渦発生器（ヴォルテックスジェネレータ、エアロスタビライジングフィンなどとも呼ばれる。）である。上述した突起部７が形成されることによって、吹出し口４から吹き出される空気は、ルーバ６に沿って流れ、突起部７の下流側における風向調整板の表面に常時乱流が発生する。そして、突起部７は、境界層剥離を抑制して、乱流化された境界層が維持するため、ルーバ６の表面において、空気の流れの剥離が遅れ、空気抵抗が減少する。   The protrusion 7 is a vortex generator (also called a vortex generator or an aerostabilizing fin). By forming the protrusion 7 described above, the air blown out from the outlet 4 flows along the louver 6, and a turbulent flow is always generated on the surface of the wind direction adjusting plate on the downstream side of the protrusion 7. And since the protrusion part 7 suppresses boundary layer peeling and the boundary layer made into turbulent flow maintains, peeling of the flow of air is delayed on the surface of the louver 6, and air resistance decreases.

したがって、ルーバ６に沿って空気が流れやすくなり、突起部７が形成されていないルーバと比べて、ルーバ６に沿って流れる風量を増加させることができる。よって、従来と比べて送風機の回転数を同一としても吹出し口４からの風量を上げることができる。また、従来と比べて風量を維持する場合は、送風機の回転数を減少させることができる。したがって、本実施形態によれば、送風機を要因とする騒音を低減できる。   Therefore, air can easily flow along the louver 6, and the amount of air flowing along the louver 6 can be increased as compared with a louver in which the protrusion 7 is not formed. Therefore, the air volume from the outlet 4 can be increased even if the number of rotations of the blower is the same as in the prior art. Moreover, when maintaining an air volume compared with the past, the rotation speed of an air blower can be decreased. Therefore, according to this embodiment, the noise caused by the blower can be reduced.

また、ルーバ６の表面において空気抵抗が減少することから、吹出し口４の外部の空気を巻き込みにくくなる。その結果、冷房運転時において湿度の高い空気が吹出し口４に接触しなくなり、吹出し口４で発生する結露を抑制できる。   In addition, since air resistance decreases on the surface of the louver 6, it becomes difficult to entrain air outside the outlet 4. As a result, high-humidity air does not come into contact with the air outlet 4 during the cooling operation, and condensation occurring at the air outlet 4 can be suppressed.

なお、突起部７は、ルーバ６の長手方向、すなわち、空気の流れ方向に対して垂直方向に複数配置される。これにより、ルーバ６が空気の流れ方向に対して垂直方向に長い長尺状板材であるときにも、ルーバ６の長手方向のほぼすべての領域にわたって空気抵抗を減少させることができる。   A plurality of protrusions 7 are arranged in the longitudinal direction of the louver 6, that is, in the direction perpendicular to the air flow direction. Thereby, even when the louver 6 is a long plate material that is long in the direction perpendicular to the air flow direction, the air resistance can be reduced over almost the entire region of the louver 6 in the longitudinal direction.

ルーバ６の長手方向の長さによっては、突起部７は、ルーバ６の長手方向の長さ内に複数ではなく、一つのみ配置されてもよい。   Depending on the length of the louver 6 in the longitudinal direction, the protrusions 7 may be arranged in the length of the louver 6 in the longitudinal direction instead of being plural.

さらに、突起部７は、ルーバ６の両面側に形成されてもよいし、ルーバ６の一面側のみに形成されてもよい。これにより、ルーバ６の両面側に突起部７が形成されれば、ルーバ６の板面の延長方向に向けて風量を増加させることができる。また、ルーバ６の一面側のみに突起部７が形成される場合、突起部７が形成されたルーバ６の一面に当たったほうの空気の風量がより増加する。すなわち、空気の風量を増加させたいほうの面に突起部７が設けられればよい。   Further, the protrusions 7 may be formed on both sides of the louver 6, or may be formed only on one side of the louver 6. Thereby, if the projections 7 are formed on both sides of the louver 6, the air volume can be increased in the extending direction of the plate surface of the louver 6. Moreover, when the projection part 7 is formed only in the one surface side of the louver 6, the air volume of the air which contacted one surface of the louver 6 in which the projection part 7 was formed increases more. That is, the protrusion 7 should just be provided in the surface which wants to increase the air volume of air.

なお、上述した突起部７は、細長い流線型形状を有し、フラップ５又はルーバ６の平滑な板面から凸状に突起しているものであるとしたが、本発明はこの例に限定されない。吹出し口から吹き出される空気が、風向調整板に沿って流れた結果、突起部の下流側における風向調整板の表面に常時乱流を発生させ、境界層剥離を抑制して、乱流化された境界層を維持する形状を有するものであれば、他の形状でもよい。例えば、フラップ５又はルーバ６の平滑な板面から凸状に突起しており、平面視が楕円形で半楕円球形状のもの、平面視がひし形で四角錐形状のものなどが例として挙げられる。   The protrusion 7 described above has an elongated streamline shape and protrudes in a convex shape from the smooth plate surface of the flap 5 or the louver 6. However, the present invention is not limited to this example. As a result of the air blown from the outlet flowing along the wind direction adjusting plate, a turbulent flow is always generated on the surface of the wind direction adjusting plate on the downstream side of the protrusion, and the boundary layer separation is suppressed and turbulent flow is generated. Any other shape may be used as long as it has a shape that maintains the boundary layer. For example, the flat plate surface of the flap 5 or the louver 6 protrudes in a convex shape, and the plan view has an elliptical shape and a semi-elliptical sphere shape. .
