Description

本発明は、遠心送風機に関する。   The present invention relates to a centrifugal blower.

ダクトファンなどの換気送風機器、空気調和機などに組み込まれて使用される従来の遠心送風機の構造は次に示す通りである。ファンケーシングだけにより自立して使用する遠心送風機、すなわち空気調和機等の機器に組み込まれて使用される遠心送風機のファンケーシングは、長方形状の側板の四辺にフランジ部が設けられている。フランジ部は、端部が曲げられ、立ち上げられて形成されている。これにより側板の強度が増し、遠心送風機は自立して固定され、空気調和機等の機器に直接固定される。   The structure of a conventional centrifugal fan used by being incorporated in a ventilation fan device such as a duct fan or an air conditioner is as follows. A centrifugal blower that is used independently by a fan casing, that is, a centrifugal blower fan casing that is used by being incorporated in a device such as an air conditioner, is provided with flange portions on four sides of a rectangular side plate. The flange portion is formed by bending an end portion and raising the flange portion. As a result, the strength of the side plate is increased, and the centrifugal fan is fixed independently and is directly fixed to a device such as an air conditioner.

以下、従来の遠心送風機の斜視図である図４を参照しながら説明する（例えば、特許文献１を参照）。図４に示すように遠心送風機１０１は、ケーシング１０２とケーシング１０２に内蔵された羽根車１０３とから構成される。ケーシング１０２は、吸込口１０４を備えた側板１０５と、スクロール１０６と、モータ１０７を固定したモータ固定側板１０８とから構成されている。羽根車１０３は、モータ１０７に固定されている。   Hereinafter, it demonstrates, referring FIG. 4 which is a perspective view of the conventional centrifugal blower (for example, refer patent document 1). As shown in FIG. 4, the centrifugal blower 101 includes a casing 102 and an impeller 103 built in the casing 102. The casing 102 includes a side plate 105 having a suction port 104, a scroll 106, and a motor fixed side plate 108 to which a motor 107 is fixed. The impeller 103 is fixed to the motor 107.

モータ１０７の駆動により羽根車１０３が回転すると、吸込気流１０９が吸込口１０４より羽根車１０３を介してケーシング１０２内に流入する。羽根車１０３から吹き出した気体は、ケーシング１０２内において昇圧され、動圧から静圧へと変換されて吐出口１１０から吐出気流１１１となって流出される。   When the impeller 103 rotates by driving the motor 107, the suction airflow 109 flows into the casing 102 from the suction port 104 through the impeller 103. The gas blown out from the impeller 103 is pressurized in the casing 102, converted from dynamic pressure to static pressure, and flows out from the discharge port 110 as a discharge airflow 111.

遠心送風機１０１は、ケーシング１０２だけにより自立して使用できるよう側板１０５と、モータ固定側板１０８とは長方形状であり、四辺にフランジ部１１２が設けられている。フランジ部１１２が補強リブとなり、側板１０５とモータ固定側板１０８とが面方向に反ったり、歪んだりするのを防止する。その結果、側板１０５とモータ固定側板１０８との強度が増し、遠心送風機１０１はケーシング１０２だけにより自立して固定され、空気調和機等の機器に直接固定される。   In the centrifugal blower 101, the side plate 105 and the motor fixing side plate 108 are rectangular so that they can be used independently only by the casing 102, and flange portions 112 are provided on four sides. The flange portion 112 serves as a reinforcing rib to prevent the side plate 105 and the motor fixing side plate 108 from being warped or distorted in the surface direction. As a result, the strength of the side plate 105 and the motor fixing side plate 108 is increased, and the centrifugal blower 101 is fixed independently by the casing 102 and is directly fixed to a device such as an air conditioner.

図５は従来の遠心送風機の梱包時の天面図であり、遠心送風機１０１が梱包された場合の天面から見た図である。図４、図５に示すように遠心送風機１０１では、一般的にモータ１０７の自重はモータ固定側板１０８により支えられる。モータ固定側板１０８に加わったモータ１０７の自重は、ケーシング１０２全体によって支えられるよう、吸込口１０４が梱包外箱１１３の底面１１４側になる向きにて梱包される。   FIG. 5 is a top view of the conventional centrifugal blower when packed, and is a view seen from the top when the centrifugal blower 101 is packed. As shown in FIGS. 4 and 5, in the centrifugal blower 101, the weight of the motor 107 is generally supported by the motor fixing side plate 108. The weight of the motor 107 applied to the motor fixing side plate 108 is packed in such a direction that the suction port 104 is on the bottom surface 114 side of the outer packaging box 113 so that it is supported by the entire casing 102.

しかし遠心送風機１０１は直方体または立方体に形成されていて、梱包状態にて落下した場合、損傷を受けやすい角部１１５を有している。角部１１５が梱包状態における落下の衝撃から保護されるためには、梱包外箱１１３と遠心送風機１０１本体との間に緩衝材等の緩衝部分１１６が必要であった。そのため緩衝部分１１６の梱包の体積が大きくなる、という課題があった。   However, the centrifugal blower 101 is formed in a rectangular parallelepiped or a cube, and has corner portions 115 that are easily damaged when dropped in a packed state. In order to protect the corner portion 115 from the impact of dropping in the packaged state, a buffer portion 116 such as a buffer material is required between the outer packaging box 113 and the centrifugal blower 101 main body. Therefore, there has been a problem that the volume of packing of the buffer portion 116 is increased.

そこで本発明の遠心送風機は、スクロールを備えたケーシングと、ケーシングに内蔵された羽根車とを備えている。ケーシングは吸込口を有する側板と、モータを固定したモータ固定側板とを備え、モータに羽根車が固定されている。そして側板とモータ固定側板との外形は、長方形の四隅が切り落とされた形状であり、側板とモータ固定側板とには、周囲に壁状に立ち上がるフランジ部が設けられている。 Therefore, the centrifugal blower of the present invention includes a casing having a scroll and an impeller built in the casing. The casing includes a side plate having a suction port and a motor fixing side plate to which the motor is fixed, and the impeller is fixed to the motor. The contour of the side plates and the motor fixing plate, the shape der four corners is cut off rectangle is, the side plates and the motor fixing plate, is provided with a flange portion which rises like a wall around.

このような遠心送風機では、底面が遠心送風機の外形寸法とほぼ同等の梱包外箱に入れられ梱包状態にされた場合、切り落とし部分と梱包外箱との間に空間が形成される。すなわち梱包状態にて遠心送風機が落下した場合、損傷を受けやすい角部がなくなる。その結果、遠心送風機の梱包時に角部に緩衝材等が設けられる必要がなく、梱包体積が大きくなることがない。   In such a centrifugal blower, when the bottom surface is put into a packaging outer box substantially equal to the outer dimensions of the centrifugal blower and put into a packaging state, a space is formed between the cut-off portion and the outer packaging box. That is, when the centrifugal blower falls in the packaged state, there is no corner that is easily damaged. As a result, there is no need to provide a cushioning material or the like at the corners when packing the centrifugal blower, and the packing volume does not increase.

以下、本発明の実施の形態について図面を参照しながら説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（実施の形態）
図１は、本発明の実施の形態の遠心送風機の斜視図である。図１に示すように遠心送風機１は、ケーシング２と、ケーシング２に内蔵された羽根車３とから構成される。ケーシング２は、吸込口４を備えた側板５と、スクロール６と、モータ７を固定したモータ固定側板８とから構成されている。 (Embodiment)
FIG. 1 is a perspective view of a centrifugal blower according to an embodiment of the present invention. As shown in FIG. 1, the centrifugal fan 1 includes a casing 2 and an impeller 3 built in the casing 2. The casing 2 includes a side plate 5 having a suction port 4, a scroll 6, and a motor fixing side plate 8 to which a motor 7 is fixed.

羽根車３は、モータ７の回転軸に固定されている。モータ７の駆動により羽根車３が回転すると、吸込気流９が吸込口４より羽根車３を介してケーシング２内に流入する。羽根車３から吹き出した気体は、ケーシング２内において昇圧され、動圧から静圧へと変換されて吐出口１０から吐出気流１１となって流出される。   The impeller 3 is fixed to the rotating shaft of the motor 7. When the impeller 3 is rotated by driving the motor 7, the suction airflow 9 flows into the casing 2 from the suction port 4 through the impeller 3. The gas blown out from the impeller 3 is increased in pressure in the casing 2, converted from dynamic pressure to static pressure, and discharged from the discharge port 10 as a discharge airflow 11.

側板５とモータ固定側板８との外形は、吸込口４に正対して見ると、長方形の四隅２０が切り落とされた形状である。そして、側板５とモータ固定側板８との長辺１２同士、短辺１３同士が平行になるように、側板５とモータ固定側板８とが配置されることが好ましい。また側板５とモータ固定側板８との長辺１２同士、短辺１３同士は同寸法であることが好ましい。このように側板５とモータ固定側板８との外形は、八角形状である。また、側板５とモータ固定側板８とには、周囲に壁状に立ち上がるフランジ部１４が設けられている。   The outer shape of the side plate 5 and the motor fixing side plate 8 is a shape in which the four corners 20 of the rectangle are cut off when viewed from the suction port 4. The side plate 5 and the motor fixing side plate 8 are preferably arranged so that the long sides 12 and the short sides 13 of the side plate 5 and the motor fixing side plate 8 are parallel to each other. Further, it is preferable that the long sides 12 and the short sides 13 of the side plate 5 and the motor fixing side plate 8 have the same dimensions. Thus, the outer shape of the side plate 5 and the motor fixing side plate 8 is an octagonal shape. Further, the side plate 5 and the motor fixing side plate 8 are provided with flange portions 14 that rise in a wall shape around the periphery.

図２は、本発明の実施の形態の遠心送風機のモータ固定側板の板金展開図である。すなわち、モータ固定側板８のフランジ部１４形成前の板金展開図である。図２の折曲部１５は、モータ固定側板８において隣接する四隅２０の端部２０ａ同士を結ぶ線である。また図１の側板５の折曲部１５も、隣接する四隅２０の端部２０ａ同士を結ぶ線である。そしてフランジ部１４は、折曲部１５から外側に折曲部１５と平行に設けられ、折曲部１５が折り曲げられて形成されている。   FIG. 2 is a development view of the metal plate of the motor fixing side plate of the centrifugal blower according to the embodiment of the present invention. That is, it is a sheet metal development view before the flange portion 14 of the motor fixing side plate 8 is formed. 2 is a line that connects the end portions 20a of the four corners 20 adjacent to each other in the motor fixing side plate 8. As shown in FIG. Further, the bent portion 15 of the side plate 5 in FIG. 1 is also a line connecting the end portions 20a of the four corners 20 adjacent to each other. The flange portion 14 is provided outside the bent portion 15 in parallel with the bent portion 15, and is formed by bending the bent portion 15.

折曲部１５は、長辺１２に接して設けられる。また短辺１３側に、長辺１２に沿って延長した延長部分１６が形成されている。すなわちフランジ部１４は、折曲部１５の両端から延長された延長部分１６を備えている。そして短辺１３部分のフランジ部１４は、折曲線１５ａにより折り曲げられ形成される。その後、隣り合う２つの延長部分１６が重ねられて、図１に示す短辺１３部分のフランジ部１４が形成される。また四隅２０は同じ形状に切り落とされることにより、フランジ部１４の形成が容易になる。   The bent portion 15 is provided in contact with the long side 12. Further, an extended portion 16 extending along the long side 12 is formed on the short side 13 side. That is, the flange portion 14 includes an extended portion 16 that is extended from both ends of the bent portion 15. And the flange part 14 of the short side 13 part is bent and formed by the folding line 15a. Then, two adjacent extended portions 16 are overlapped to form the flange portion 14 of the short side 13 portion shown in FIG. The four corners 20 are cut into the same shape, so that the flange portion 14 can be easily formed.

上記構成による作用、効果について説明する。図３は、本発明の実施の形態の遠心送風機の梱包時の天面図である。図３は、遠心送風機１が梱包された場合の梱包外箱１８の天面側から見た図である。すなわち遠心送風機１は、モータ固定側板８側を天面側にして梱包外箱１８に入れられる。梱包外箱１８は、底面１７が図１の遠心送風機１の側板５の外形寸法とほぼ同じである。より詳細には、底面１７は側板５の長辺１２が形成する長方形よりも少しだけ大きい。   The operation and effect of the above configuration will be described. Drawing 3 is a top view at the time of packing of a centrifugal blower of an embodiment of the invention. FIG. 3 is a view seen from the top surface side of the outer packaging box 18 when the centrifugal blower 1 is packed. That is, the centrifugal blower 1 is placed in the outer packaging box 18 with the motor fixing side plate 8 side being the top side. The outer packaging box 18 has a bottom surface 17 that is substantially the same as the outer dimensions of the side plate 5 of the centrifugal blower 1 of FIG. More specifically, the bottom surface 17 is slightly larger than the rectangle formed by the long side 12 of the side plate 5.

そして遠心送風機１が梱包された場合、側板５とモータ固定側板８との切り落とし部分と、梱包外箱１８との間に空間１９が形成される。一般的に梱包状態にて機器が落下した場合、損傷を受けやすい部分は機器の角部である。図３に示すように遠心送風機１ではこの角部をなくし、この部分に空間１９が設けられている。そのため遠心送風機１が梱包状態にて落下した場合、空間１９が緩衝空間となり、落下による衝撃を吸収する。つまり梱包外箱１８が変形しながら衝撃を吸収し、遠心送風機１の損傷が防がれる。   When the centrifugal blower 1 is packed, a space 19 is formed between the cut-off portion between the side plate 5 and the motor fixing side plate 8 and the outer packaging box 18. In general, when a device falls in a packaged state, a portion that is easily damaged is a corner portion of the device. As shown in FIG. 3, the centrifugal blower 1 eliminates the corner portion, and a space 19 is provided in this portion. Therefore, when the centrifugal blower 1 falls in a packaged state, the space 19 becomes a buffer space and absorbs the impact caused by the fall. That is, the shock is absorbed while the outer packaging box 18 is deformed, and the centrifugal blower 1 is prevented from being damaged.

また、図１に示す側板５とモータ固定側板８との長辺１２同士、短辺１３同士が平行かつ同寸法であり、遠心送風機１を入れる図３の梱包外箱１８の縦横寸法も同寸法であることが好ましい。この構成によれば、図３の遠心送風機１が梱包される際の遠心送風機１の向きが無くなり、梱包時の遠心送風機１の向きの間違いが防止され、空間１９が確実に確保される。   Further, the long sides 12 and the short sides 13 of the side plate 5 and the motor fixing side plate 8 shown in FIG. 1 are parallel and have the same dimensions, and the vertical and horizontal dimensions of the outer packaging box 18 of FIG. It is preferable that According to this configuration, the direction of the centrifugal blower 1 when the centrifugal blower 1 of FIG. 3 is packed is eliminated, an error in the direction of the centrifugal blower 1 during packing is prevented, and the space 19 is reliably secured.

なお、本実施の形態では図１の側板５とモータ固定側板８との外形は、八角形状としているが、角部が丸くても良い。すなわち側板５とモータ固定側板８との外形の八角形状は、角部が丸い略八角形状も含む。側板５とモータ固定側板８とが略八角形状であっても、遠心送風機１は梱包状態における落下の衝撃から保護される。   In this embodiment, the outer shape of the side plate 5 and the motor fixing side plate 8 in FIG. 1 is an octagonal shape, but the corner may be round. That is, the octagonal shape of the outer shape of the side plate 5 and the motor fixing side plate 8 includes a substantially octagonal shape with rounded corners. Even if the side plate 5 and the motor fixing side plate 8 are substantially octagonal, the centrifugal blower 1 is protected from the impact of dropping in the packaged state.

また図１の側板５とモータ固定側板８とは、対向する２組の長辺１２と、対向する２組の短辺１３との八辺を備えるとしたが、少なくとも八辺であればよく、辺の数を増やして八辺以上としてもよい。   In addition, the side plate 5 and the motor fixing side plate 8 in FIG. 1 are provided with eight sides of two opposing long sides 12 and two opposing short sides 13, but it is sufficient that they are at least eight sides. It is also possible to increase the number of sides to more than eight sides.

また、図１に示す側板５とモータ固定側板８との短辺１３部分のフランジ部１４は、図２に示す隣り合う２つの延長部分１６を重ねるようにして形成した。しかし、短辺１３部分にもフランジ部１４と連結した連結フランジ部が設けられ、フランジ部１４と一緒に折り曲げられて短辺１３部分のフランジ部１４が形成されても良い。   Moreover, the flange part 14 of the short side 13 part of the side plate 5 and the motor fixing side plate 8 shown in FIG. 1 was formed so that two adjacent extension parts 16 shown in FIG. However, a connecting flange portion connected to the flange portion 14 may also be provided in the short side 13 portion, and the flange portion 14 of the short side 13 portion may be formed by being bent together with the flange portion 14.

また別部品を設けることなく、図１のフランジ部１４が折り曲げ加工にて簡単に形成される。さらにフランジ部１４が補強リブとなるため、側板５とモータ固定側板８とが面方向に反ったり、歪んだりするのが防止される。   Moreover, the flange part 14 of FIG. 1 is easily formed by bending without providing another part. Furthermore, since the flange portion 14 becomes a reinforcing rib, the side plate 5 and the motor fixing side plate 8 are prevented from warping or distorting in the surface direction.

また図２に示すフランジ部１４は、延長部分１６が重ねられて形成されているため運搬時、および吊り固定時にフランジ部１４が保持された場合、力が加わる方向に隣り合うフランジ部１４同士が連結されるので、フランジ部１４の強度が強くなる。   Further, since the flange portion 14 shown in FIG. 2 is formed by overlapping the extended portion 16, when the flange portion 14 is held during transportation and when being suspended and fixed, the flange portions 14 adjacent to each other in the direction in which a force is applied. Since they are connected, the strength of the flange portion 14 is increased.

このような構成により、図１に示す側板５とモータ固定側板８との強度が増し、遠心送風機１はケーシング２だけにより自立して固定される。そのため遠心送風機１は、空気調和機等の機器に直接固定される。また遠心送風機１の梱包時、角部に緩衝材等の緩衝部分が設けられる必要がなく、梱包の体積が小さくなる。   With such a configuration, the strength of the side plate 5 and the motor fixing side plate 8 shown in FIG. 1 is increased, and the centrifugal blower 1 is fixed independently by the casing 2 alone. Therefore, the centrifugal blower 1 is directly fixed to a device such as an air conditioner. Further, when the centrifugal blower 1 is packed, it is not necessary to provide a buffer portion such as a buffer material at the corner portion, and the volume of the package is reduced.

本発明は遠心送風機に限られることなく、設備機器の機器梱包にも適用できる。   The present invention is not limited to the centrifugal blower but can also be applied to equipment packaging of equipment.
