【0002】
【従来の技術】
従来、図5に示すような電気掃除機が知られている。図5において、1は電気掃除機本体、2は電気掃除機本体1内の後部に形成された電動送風機室、3は電動送風機室2に設けられて図示しない集塵室を負圧にする電動送風機、4は電気掃除機本体1の後壁1aに設けられた排気口である。
【0003】
電動送風機3は、図示しない遠心ファンと、この遠心ファンを回転させる電動モータ(図示せず)とを備え、この電動モータが筒状のモータケース5に収納されている。
【0004】
このモータケース5には、複数の排気穴5aが形成され、この複数の排気穴5aから電動モータを冷却するために遠心ファンによって電動モータ内に送り込まれた空気が排出され、この排出された空気が排気口4から電気掃除機本体1の外部に排出される。
【0005】
【発明が解決しようとする課題】
しかしながら、上述の電気掃除機にあっては、電動送風機3内で電動モータや遠心ファンの回転による騒音が発生し、この騒音が排気とともにモータケース5の複数の排気穴5aを介して排気口4から電気掃除機本体1の外部へ出るが、複数の排気穴5aと排気口4との風路距離が短いことにより、電動送風機3の内部で発生した大きな騒音がそのまま電気掃除機本体外部に出ることになる。このため、騒音が大きいという問題があった。
【0006】
そこで、この発明の目的は、低騒音化を図ることができる電気掃除機を提供することにある。
【0007】
【課題を解決するための手段】
この目的を達成するため、請求項1の発明は、電気掃除機本体内の後部にコードリール収納室と電動送風機室とが隔壁を介して並設され、前記電動送風機室内に配設された電動送風機の後部が前記本体ケースの支持壁に支持され、前記支持壁と前記電気掃除機本体の後部壁との間に排気室が形成され、前記電動送風機を覆うカバーが前記電動送風機室内に配設され、前記電動送風機の排気を排気する排気穴が前記カバーに形成され、前記電動送風機室を前記排気室に連通させる連通口が前記支持壁に設けられ、前記電気掃除機本体の後部壁に排気口が設けられた電気掃除機であって、前記排気穴を前記カバーの前記コードリール収納室側に前記電動送風機室の底部に向けて設け、前記連通口を前記コードリール収納室と反対側に位置させて前記支持壁の下部に設けることにより、前記電動送風機室の底部の前記コードリール収納室側から反対側に向かう排気風路が前記カバーの下方に形成される電気掃除機としたことを特徴とする。
【0008】
【発明の実施の形態】
以下、この発明に係る電気掃除機の実施の形態を図面に基づいて説明する。
【0009】
図1,2および図3において、10は電気掃除機本体であり、この電気掃除機本体10内には、電動送風機12を設けた電動送風機室11と、この電動送風機室11に隣接(図1,3において左側)して電源コードリール31を収納したコードリール室30とが並設され、これら並設した電動送風機室11とコードリール室30との後側(図2において右側)に排気室40が形成されている。電気掃除機本体10の後部壁10aには排気口41が形成され、この排気口41を介して排気室40と外気とが連通されている。排気口41の内面(図2において左側)には排気フィルタ42(図2参照)が取り付けられている。
【0010】
電気掃除機本体10の前側(図1において左側)には、図示しない集塵室が形成され、この集塵室と電動送風機室11とは隔壁(図示せず)によって区画されている。また、電動送風機室11とコードリール室30とは隔壁30aによって区画されており、電動送風機室11と排気室40とは電動送風機12の後部12aを支持する支持壁13とによって区画されている。
【0011】
この支持壁13は、電気掃除機本体10に設けた中ケース14の天板壁14aから垂下する上支持壁13aと、電気掃除機本体10の底壁10bから立設する下支持壁13bとを有し、この下支持壁13bの下部の右側(図3において)には、電動送風機室11と排気室40とを連通する連通口13cが形成されている。中ケース14の天板壁14aには図示しない回路基板が取り付けられている。
【0012】
また、電動送風機12は、図示しない遠心ファンと、この遠心ファンの後側に遠心ファンを回転させる図示しない電動モータとを備え、これら遠心ファンと電動モータとが筒状のケース15に収納され、このケース15の前側(集塵室側)の大径のファンケース部15aに図示しない遠心ファンが収納されるとともに、後側の小径のモータケース部15bに図示しない電動モータが収納されている。
【0013】
そして、このモータケース部15bの後部側(電動送風機室11の支持壁13側)外周面15cには、複数の排気口15dが開口している。18は電動モータのカーボンブラシである。また、モータケース部15bの後面15eには、図示しない電動モータの軸受部を覆う軸受部15fが突出している。このケース15のファンケース部15aには振動吸収用のゴムカバー16が取り付けられ、モータケース部15bを覆ってカバー17がゴムカバー16の一部を介してファンケース部15aに取り付けられている。
【0014】
カバー17は、図4(a)、(b)に示すように、ゴムカバー16の端部を介してケース15のファンケース部15aに嵌合する嵌合筒部17aとケース15のモータケース部15bを覆うカバー本体部17bとを一体に形成し、このカバー本体部17bの後面17cには略中央に嵌合穴17dが開口されている。
【0015】
この嵌合穴17dにはモータケース15bの軸受部15fを覆うゴム製のキャツプ19が嵌合され、このキャツプ19を介して支持壁13が電動送風機12の後部12aを支持している。
【0016】
また、このカバー本体部17bの下側半分は小径状に形成し、嵌合筒部17aの下側とカバー本体部17bの下側との間に段差17eが形成され、この段差17eはカバー本体部17bの下側からカバー本体部17bの右側外周面(図3において)の中間位置まで形成されている。また、カバー本体部17bの下面17fの左側(図4において)からその左側面にかけて開口17g(排気穴)が形成され、この開口17gは電動送風機室11の底部11aに対向した開口面17hとコードリール収納室30に対向した開口面17jとを有している。
【0017】
そして、カバー本体部17bの下面17fと支持壁13と電動送風機室11の底部11a等で、開口17gから排出される空気をカバー本体部17bの下側を通って連通口13cへ案内する案内風路20が形成されている。21は案内風路20の底部20aに敷かれた消音材21である。
【0018】
次に、このような構成の電気掃除機の作用を説明する。
【0019】
電気掃除機が作動されると、図示しない遠心ファンが電動モータによって回転される。
【0020】
すると、この遠心ファンによって集塵室が負圧にされるとともに、遠心ファンによってモータケース部15b内に空気が送り込まれていく。この空気によって電動モータが冷却されていく。このモータケース部15b内に送り込まれた空気は、モータケース部15bの複数の排気口15dからカバー17のカバー本体部17b内に排出され、この排出された空気がカバー本体部17bの開口(排気穴)17gからコードリール収納室30と電動送風機室11の底部11aとに向けて排出される。
【0021】
この開口(排気穴)17gから排出される空気とともに電動モータと遠心ファンとの回転によって発生した騒音が開口(排気穴)17gからコードリール31と電動送風機室11の底部11aとに向けて放出されるが、コードリール31や隔壁30a等によって電気掃除機本体10の側面から外部にほとんど漏れない。また、電動送風機室11の底部11aに向けて放出される騒音が電動送風機室11の底部11aから電気掃除機本体10の外部へ漏れても、この漏れた騒音は床面に向けて放出される状態となるので、その騒音は小さなものになる。また、電動送風機室11の底部11a近くに設けられており、しかも、開口(排気穴)17gから騒音が下方に向けて放出されることにより、電気掃除機本体10の上面から騒音がはほとんど漏れない。
【0022】
そして、開口(排気穴)17gから排出された空気は案内風路(排気風路)20を通って連通口13cから排気室40に排出され、排気室40に排出された空気は排気口41を介して電気掃除機本体10の外部に排出される。
【0023】
この開口(排気穴)17gから排出された空気とともに放出された騒音は、案内風路(排気風路)20を通って連通口13cへ案内されていくが、案内風路(排気風路)20はコードリール収納室の隣接位置から電気掃除機本体10の右側壁部10aまで延びて長くなっている。このことにより、その騒音は減衰され、また、排気風路20の底部20aに敷かれた消音材21によって騒音はさらに減衰する。
【0024】
この減衰された騒音が連通口13cからこの連通口13cよりも広い空間の排気室40に放出されることにより、さらに、騒音は小さくなって排気口41から電気掃除機本体10の外部に放出される。
【0025】
このように、電気掃除機本体10の側面および上面から騒音はほとんど漏れず、また、底部11aから漏れる騒音は小さく、さらに、排気口41から外部に放出される騒音も小さいので、電気掃除機本体10から放出される騒音は全体として小さなものとなり、低騒音化を図ることができることとなる。
【0026】
この状態では、案内風路(排気風路)20をカバー本体部17bと支持壁13等で形成しているので、専用の排気壁を設ける必要がないので、安価なものとなる。また、案内風路(排気風路)20をカバー本体部17bと電動送風機室11の底部11aとの間に形成したので、電気掃除機本体10を大型化させずに済むことになる。
【0027】
【発明の効果】
以上説明してきたように、請求項1の発明は、電気掃除機本体内の後部にコードリール収納室と電動送風機室とが隔壁を介して並設され、前記電動送風機室内に配設された電動送風機の後部が前記本体ケースの支持壁に支持され、前記支持壁と前記電気掃除機本体の後部壁との間に排気室が形成され、前記電動送風機を覆うカバーが前記電動送風機室内に配設され、前記電動送風機の排気を排気する排気穴が前記カバーに形成され、前記電動送風機室を前記排気室に連通させる連通口が前記支持壁に設けられ、前記電気掃除機本体の後部壁に排気口が設けられた電気掃除機であって、前記排気穴を前記カバーの前記コードリール収納室側に前記電動送風機室の底部に向けて設け、前記連通口を前記コードリール収納室と反対側に位置させて前記支持壁の下部に設けることにより、前記電動送風機室の底部の前記コードリール収納室側から反対側に向かう排気風路が前記カバーの下方に形成される構成としたので、電気掃除機本体の側面および上面から騒音はほとんど漏れず、しかも、底部から漏れる騒音は小さい。さらに、排気口から放出される騒音は小さいので、電気掃除機本体から放出される騒音は全体として小さく、低騒音化を図ることができる。

A centrifugal fan (not shown) is housed in a large-diameter fan case portion 15a on the front side (dust collection chamber side) of the case 15, and an electric motor (not shown) is housed in a small-diameter motor case portion 15b on the rear side.
[0013]
A plurality of exhaust ports 15d are opened on the outer peripheral surface 15c of the rear side (the support wall 13 side of the electric blower chamber 11) of the motor case portion 15b. 18 is a carbon brush of an electric motor. Further, a bearing portion 15f that covers a bearing portion of an electric motor (not shown) protrudes from the rear surface 15e of the motor case portion 15b. A vibration-absorbing rubber cover 16 is attached to the fan case portion 15a of the case 15, and a cover 17 is attached to the fan case portion 15a through a part of the rubber cover 16 so as to cover the motor case portion 15b.
[0014]
As shown in FIGS. 4A and 4B, the cover 17 includes a fitting cylinder portion 17 a that fits into the fan case portion 15 a of the case 15 via the end portion of the rubber cover 16 and a motor case portion of the case 15. A cover main body portion 17b that covers 15b is integrally formed, and a rear surface 17c of the cover main body portion 17b is provided with a fitting hole 17d substantially at the center.
[0015]
A rubber cap 19 that covers the bearing portion 15f of the motor case 15b is fitted into the fitting hole 17d, and the support wall 13 supports the rear portion 12a of the electric blower 12 through the cap 19.
[0016]
Further, the lower half of the cover main body portion 17b is formed in a small diameter, and a step 17e is formed between the lower side of the fitting tube portion 17a and the lower side of the cover main body portion 17b. It is formed from the lower side of the portion 17b to the middle position of the right outer peripheral surface (in FIG. 3) of the cover main body portion 17b. Further, an opening 17g (exhaust hole) is formed from the left side (in FIG. 4) of the lower surface 17f of the cover main body 17b to the left side, and this opening 17g is formed with the opening surface 17h facing the bottom 11a of the electric blower chamber 11 and the cord. And an opening surface 17j facing the reel storage chamber 30.

Reference numeral 21 denotes a sound deadening material 21 laid on the bottom 20 a of the guide air passage 20.
[0018]
Next, the operation of the vacuum cleaner having such a configuration will be described.
[0019]
When the vacuum cleaner is activated, a centrifugal fan (not shown) is rotated by the electric motor.
[0020]
Then, the dust collection chamber is made negative pressure by the centrifugal fan, and air is sent into the motor case portion 15b by the centrifugal fan. The electric motor is cooled by this air. The air sent into the motor case portion 15b is discharged into the cover main body portion 17b of the cover 17 from a plurality of exhaust ports 15d of the motor case portion 15b, and the discharged air is opened to the cover main body portion 17b (exhaust gas). Holes 17 g are discharged toward the cord reel storage chamber 30 and the bottom 11 a of the electric blower chamber 11.
[0021]
Along with the air discharged from the opening (exhaust hole) 17g , noise generated by the rotation of the electric motor and the centrifugal fan is released from the opening (exhaust hole) 17g toward the cord reel 31 and the bottom 11a of the electric blower chamber 11. However, the cord reel 31, the partition wall 30a and the like hardly leak to the outside from the side surface of the main body 10 of the vacuum cleaner. Moreover, even if the noise released toward the bottom 11a of the electric blower chamber 11 leaks from the bottom 11a of the electric blower chamber 11 to the outside of the vacuum cleaner body 10, the leaked noise is released toward the floor surface. Since it becomes a state, the noise becomes small. Moreover, it is provided near the bottom part 11a of the electric blower chamber 11, and noise is almost leaked from the upper surface of the main body 10 of the electric vacuum cleaner 10 by releasing noise downward from the opening (exhaust hole) 17g. Absent.
[0022]
The air discharged from the opening (exhaust hole) 17g passes through the guide air passage (exhaust air passage) 20 and is discharged from the communication port 13c to the exhaust chamber 40, and the air discharged to the exhaust chamber 40 passes through the exhaust port 41. Through the vacuum cleaner body 10.
[0023]
The noise released together with the air discharged from the opening (exhaust hole) 17g is guided to the communication port 13c through the guide air passage (exhaust air passage) 20, but the guide air passage (exhaust air passage) 20 Is extended from the adjacent position of the cord reel storage chamber to the right side wall portion 10a of the main body 10 of the vacuum cleaner. As a result, the noise is attenuated, and the noise is further attenuated by the silencer 21 laid on the bottom 20a of the exhaust air duct 20.
[0024]
The attenuated noise is emitted from the communication port 13c to the exhaust chamber 40 in a larger space than the communication port 13c, so that the noise is further reduced and emitted from the exhaust port 41 to the outside of the vacuum cleaner body 10. The
[0025]
Thus, almost no noise leaks from the side surface and top surface of the vacuum cleaner body 10, the noise leaking from the bottom portion 11 a is small, and the noise released to the outside from the exhaust port 41 is also small. The noise emitted from 10 becomes small as a whole, and noise reduction can be achieved.
[0026]
In this state, the guide air passage (exhaust air passage) 20 is formed by the cover main body portion 17b, the support wall 13 and the like, so that it is not necessary to provide a dedicated exhaust wall, so that it is inexpensive. Further, since the guide air passage (exhaust air passage) 20 is formed between the cover main body portion 17b and the bottom portion 11a of the electric blower chamber 11, it is not necessary to increase the size of the electric vacuum cleaner main body 10.
[0027]
