Description
【０００１】[0001]
本考案は空気調和機の室内機の送風装置に関する。 The present invention relates to an air blower for an indoor unit of an air conditioner.
【０００２】[0002]
従来の空気調和機の室内機の送風装置は、図２の様に、本体１１の空気流路内 には横長に一体形成されたクロスフローファン１２を設け、その前面下部の吹出 し口側には軸受枠１３を設け、複数の左右風向板１４を揺動自在に軸支してなる ものであった。 As shown in FIG. 2, a conventional blower for an indoor unit of an air conditioner has a cross flow fan 12 integrally formed in a horizontal direction in an air flow path of a main body 11, and is provided at a lower end of a front surface thereof on an outlet side. The bearing frame 13 is provided, and a plurality of left and right wind direction plates 14 are pivotally supported to be swingable.
【０００３】 上記従来型の空気調和機の送風装置によると、クロスフローファン１２が横長 に一体形成されているので、運転時にクロスフローファン１２を回転させるとそ の特性として、平面で見た矢印で示す様に、同ファン１２の中央部付近から吹き 出される風が強く、左右の端から吹き出される風が弱くなる傾向にある。したが って、図２に示す様に、左右の風向板１４を互いに反対方向に向けて、この吹き 出し空気流を部屋の全体にワイドに広げようとしても、クロスフローファン１２ の中央付近の吹き出し風が強いので、この中央の風の影響力を受けて、左右の吹 き出し風が内側に引き寄せられ、風向板１４を正面に向けた場合と同じ様にワイ ドに広がらず、正面側しか吹き出されない等の欠点を有していた。According to the air blower of the conventional air conditioner described above, the crossflow fan 12 is integrally formed in a horizontally long shape. Therefore, when the crossflow fan 12 is rotated during operation, its characteristic is that the arrow seen in a plane. As shown by, the wind blown from near the center of the fan 12 tends to be strong, and the wind blown from the left and right ends tends to be weak. Therefore, as shown in FIG. 2, the left and right wind direction plates 14 are directed in opposite directions, and even if an attempt is made to widen this blown-out airflow over the entire room, the area around the center of the crossflow fan 12 is Since the blowing air is strong, the blowing air on the left and right is pulled inward under the influence of this central wind, and it does not spread to the wind as in the case where the wind direction plate 14 is facing the front, It had a defect that it was only blown out.
【０００４】[0004]
本考案は上記従来型の問題点に鑑み考案されたものであって、クロスフローフ ァンの特性と風の影響力を利用して、必要に応じてワイドな吹出し空気流を得る ことができる送風装置の構造を提供することを目的とするものである。 The present invention was devised in view of the above-mentioned problems of the conventional type, and it is possible to obtain a wide blown air flow as necessary by utilizing the characteristics of the cross flow fan and the influence of the wind. It is intended to provide a structure of a blower.
【０００５】[0005]
上記の課題を解決するための本考案の空気調和機の送風装置は下記の構造を具 えてなるものである。即ち、本体の空気流路内にクロスフローファンを設け、そ の吹出し側に風向板を設けてなる空気調和機において、上記クロスフローファン を複数に分割形成し、中央のファンの回転数よりも、両側のファンの回転数が大 きくなる様に変速装置を介して連結してなるものである。 また、クロスフローファンを複数に分割形成し、これらファンを連結する動力 の伝達軸に、中央のファンの回転数よりも、両側のファンの回転数が大きくなる 様に構成された歯車装置を設けてなるものである。 The air blower for an air conditioner according to the present invention for solving the above problems has the following structure. That is, in an air conditioner in which a cross flow fan is provided in the air flow path of the main body and an air flow direction plate is provided on the outlet side, the cross flow fan is divided into a plurality of parts, and the number of revolutions of the fan at the center is lower than that of the fan. , The fans on both sides are connected via a transmission so that the number of rotations of the fans on both sides increases. In addition, a cross-flow fan is divided into multiple parts, and the gear transmission that connects the fans is equipped with a gear device configured so that the rotation speeds of the fans on both sides are higher than the rotation speed of the central fan. It will be.
【０００６】[0006]
上記の構成において、クロスフローファンを複数に分割することによって、運 転時に夫々のファンを通して吹き出される空気流の強さは、そのファンの回転数 によって左右される。この分割形成されるクロスフローファンに対して駆動装置 は一側に構成されるが、この動力装置の動力を各ファンに伝達するため、夫々の ファンを結ぶ動力の伝達軸には、例えば歯車装置を含む変速装置を設けことによ り、駆動装置による回転時に中央のファンの回転数よりも、両側のファンの回転 数が大きくなる様に構成される。ここで、左右のファンは運転時に同じ回転数に なる様に構成されている。 In the above structure, by dividing the cross flow fan into a plurality of parts, the strength of the air flow blown out through each fan during operation depends on the rotation speed of the fan. The drive unit is configured on one side of the divided cross-flow fan, but in order to transmit the power of this power unit to each fan, the power transmission shaft connecting the respective fans may be, for example, a gear unit. By providing the transmission including the above, the rotational speeds of the fans on both sides are higher than the rotational speed of the central fan when the drive device rotates. Here, the left and right fans are configured to have the same rotation speed during operation.
【０００７】 しかして、運転時にクロスフローファンを通して吹出される空気流は、回転数 の小さい中央のファンからの吹出し風が弱くなり、これよりも回転数の大きい両 側のファンからの吹出し風が強くなる。これによって、従来型の横長に一体形成 されたクロスフローファンの様に、運転時にファンの中央部付近の吹出し風が強 くなる様なことはなく、クロスフローファンの両側付近の吹出し風が強められる 傾向により、全体の吹出し風が平均化され、必要に応じて左右の風向板を互いに 反対方向に向けることによって、正面側に引寄せられることなく、両側のファン からの吹出し風は夫々の風向板の向きに沿って左右に分かれ、ワイドな吹出し空 気流を得ることができる。However, in the air flow blown out through the cross flow fan during operation, the air blown out from the central fan having a low rotation speed becomes weak, and the airflow blown from the fans on both sides having a higher rotation speed than this. Become stronger. As a result, unlike the conventional horizontally long crossflow fan, the blowing air around the center of the fan does not become strong during operation, but the blowing air near both sides of the crossflow fan is strengthened. Due to this tendency, the overall blow-out air is averaged, and by directing the left and right wind vanes in opposite directions as necessary, the blow-out winds from the fans on both sides are not attracted to the front side. It is divided into left and right along the direction of the board, and a wide airflow can be obtained.
【０００８】[0008]
以下本考案を図に示す一実施例に基づいて説明すると、図１において、１は空 気調和機の室内機の本体あって、同本体１の空気流路内にはクロスフローファン が２設けられ、その前面下部の吹出し口側には軸受枠３を設け、複数の左右風向 板４が揺動自在に軸支されている。ここで、上記クロスフローファン２は中央部 ファン２１と、左側ファン２２および右側ファン２３の三つに分割形成されてお り、これらファンを連結する動力の伝達軸には、上記中央部ファン２１の回転数 よりも、両側の左側ファン２２および右側ファン２３の回転数が大きくなる様に 構成された、例えば、遊星歯車装置等の歯車装置を含む変速装置５、６が設けら れており、しかも、運転時には左側ファン２２および右側ファン２３の回転数は 同じになる様に構成されている。 The present invention will be described below based on an embodiment shown in the drawing. In FIG. 1, reference numeral 1 is a main body of an indoor unit of an air conditioner, and two cross flow fans are provided in an air passage of the main body 1. A bearing frame 3 is provided on the lower side of the front surface on the side of the outlet, and a plurality of left and right airflow direction plates 4 are pivotally supported so as to be swingable. The cross flow fan 2 is divided into a central fan 21, a left fan 22 and a right fan 23, and the central fan 21 is connected to a power transmission shaft connecting these fans. The transmissions 5 and 6 including gear devices such as a planetary gear device are provided so that the rotation speeds of the left fan 22 and the right fan 23 on both sides are higher than the rotation speeds of the above. Moreover, the rotational speeds of the left fan 22 and the right fan 23 are configured to be the same during operation.
【０００９】 上記の構成により、クロスフローファン２を中央部ファン２１と、左側ファン ２２および右側ファン２３の三つに分割形成し、夫々のファンを結ぶ動力の伝達 軸に夫々変速装置５、６設けることにより、駆動装置による運転時に回転数の小 さい中央部ファン２１を通して吹き出される空気流が弱くなり、これよりも回転 数の大きい左側ファン２２および右側ファン２３を通して吹出される空気流が強 くなる。これによって、図示の矢印に示す様に、クロスフローファン２の中央部 付近の吹出し風が強くなる様なことはなく、クロスフローファン２の両側付近の 吹出し風が強められる傾向になり、必要に応じて左右の風向板４を互いに反対方 向に向けることによって、中央部ファン２１を通して吹き出される正面側の空気 流が弱くなり、この影響を受けることなく、左側ファン２２および右側ファン２ ３を通して吹出される空気流は夫々の風向板４の向きに沿って左右に分かれ、ワ イドな吹出し空気流を得ることができる。With the above structure, the cross flow fan 2 is divided into the central fan 21, the left fan 22 and the right fan 23, and the transmissions 5, 6 are respectively connected to the power transmission shafts connecting the respective fans. By providing it, the air flow blown out through the central fan 21 having a low rotation speed becomes weaker during the operation by the drive device, and the air flow blown out through the left fan 22 and the right fan 23 having a higher rotation speed is stronger. Become As a result, as shown by the arrow in the figure, the blowout air near the center of the crossflow fan 2 does not become strong, but the blowout air near both sides of the crossflow fan 2 tends to be strengthened. Accordingly, by directing the left and right wind direction plates 4 in opposite directions, the air flow on the front side blown out through the central fan 21 is weakened and the left side fan 22 and the right side fan 23 are not affected by this. The blown airflow is divided into right and left along the direction of each wind direction plate 4, and a wide blown airflow can be obtained.

本考案の空気調和機の送風装置によると、分割形成されるクロスフローファン に対して、夫々のファンを結ぶ動力の伝達軸に変速装置を設けことにより、駆動 装置による回転時に中央のファンの回転数よりも、両側のファンの回転数が大き くなる。この回転数の差によるクロスフローファンの特性を利用して、中央のフ ァンからの吹出し風を弱く、両側のファンからの吹出し風を強くすることができ る。これによって、従来型の様にファンの中央部付近の吹出し風が強くなる様な ことはなく、クロスフローファンの両側付近の吹出し風が強められる傾向によっ て、正面側に吹き出し風が集中することなく、全体の吹出し風が平均化され心地 良い空気流を得ることができる一方、必要に応じて左右の風向板を互いに反対方 向に向けることによって、両側のファンからの吹出し風は夫々の風向板の向きに 沿って左右に分かれてワイドな吹出し空気流を得ることができる。 According to the blower of the air conditioner of the present invention, a transmission is provided on the power transmission shaft connecting the respective fans to the separately formed cross-flow fan, so that the rotation of the central fan during rotation by the drive device. The number of rotations of the fans on both sides is higher than the number of rotations. By utilizing the characteristics of the cross-flow fan due to the difference in the number of revolutions, it is possible to weaken the air blown from the central fan and to increase the air blown from the fans on both sides. As a result, unlike the conventional type, the blowout air near the center of the fan does not become strong, but the blowout air near both sides of the crossflow fan tends to be strengthened, so that the blowout air is concentrated on the front side. The airflow from the entire fan can be averaged to obtain a comfortable airflow, while the airflow from the fans on both sides can be adjusted by turning the left and right wind vanes in opposite directions as necessary. It is possible to obtain a wide blown air flow by splitting it into left and right along the direction of the wind direction plate.
