【発明の詳細な説明】
【0001】
【発明の属する技術分野】
本発明は、一般家庭で使用される電気掃除機に関するものである。
【0002】
【従来の技術】
従来の電気掃除機を、図5〜図6を用いて説明する。
【0003】
延長管21の一端に電動機(図示せず)を内蔵した床ノズル22を接続し、延長管21の他端には先端パイプ24が接続される。先端パイプ24は掃除機本体23内の電動送風機(図示せず)の運転を制御する制御回路(図示せず)を内蔵している。
【0004】
ホ−ス26は、その一端に、前記本体23の吸気口23aに接続される接続パイプ25を備え、他端に先端パイプ24が接続されている。前記ホ−ス26には、図6に示すように、ホ−ス26の強度確保用並びに床ノズル22及び前記制御回路への通電用に絶縁被覆補強線27が、所定の間隔を保って複数螺旋状に配設され、さらに外皮テ−プ28で覆われている。絶縁被覆補強線27は、硬鋼線29とそれを覆う絶縁被覆材30で形成され、前記ホ−ス26の質量は、前記外皮テ−プ28、硬鋼線29及び絶縁被覆材30により決定される。
【0005】
通常、掃除機本体23の電動送風機の運転を制御する回路に流れる消費電流は、床ノズル22に供給される消費電流に較べ小さいものである。
【0006】
【発明が解決しようとする課題】
しかしながら、このような従来の掃除機においては、消費電流の大きさに関わらず、同一径の硬鋼線29が使用されていた。即ち、小さい消費電流が流れる制御回路に接続される絶縁被覆補強線27の硬鋼線29の径と、大きな消費電流が流れる床ノズル22に接続される絶縁被覆補強線27の硬鋼線29の径とが同一なため、ホース26が太く、重くなっており、ホ−ス26の軽量化の妨げとなり、また使用勝手の悪いホ−スとなっていた。
【0007】
本発明は以上のような従来の課題を解決しようとするものであって、ホ−スを軽量化して、操作性の良い電気掃除機を提供することを目的としている。
【0008】
【課題を解決するための手段】
上記目的を達成するために本発明は、ホ−スに線径の異なる硬鋼線を複数螺旋状に配設し、線径の小さい方の硬鋼線を制御回路に電気的に接続したもので、硬鋼線を細くした分、軽量化を促進するものである。
【0009】
【発明の実施の形態】
本発明の請求項1記載の発明は、電動送風機を内蔵した本体と、前記電動送風機の運転を制御する制御回路と、前記制御回路を内蔵する手元ハンドルと、一端が本体に接続され他端が前記手元ハンドルに接続されたホ−スを有し、前記ホ−スに、線径の異なる硬鋼線を複数螺旋状に配し、線径の小さい方の前記硬鋼線を前記制御回路に電気的に接続したもので、制御回路と電気的に接続される硬鋼線の径が細い分、ホースを軽くすることができるものである。
【0010】
本発明の請求項2記載の発明は、電動送風機を内蔵した本体と、前記電動送風機の運転を制御する制御回路と、前記制御回路を内蔵する手元ハンドルと、一端が本体に接続され他端が前記手元ハンドルに接続されたホ−スと、延長管を介して前記手元ハンドルと接続される電動機を内蔵する床ノズルとを有し、前記ホ−スに、線径の異なる硬鋼線を螺旋状に配し、線径の小さい前記硬鋼線を前記制御回路側に、線径の大きい前記硬鋼線を前記床ノズル側に電気的に接続するもので、硬鋼線の径を細くした分、ホースを軽くすることができるものである。
【0011】
本発明の請求項3記載の発明は、電動送風機を内蔵した本体と、前記電動送風機の運転を制御する制御回路と、前記制御回路を内蔵する手元ハンドルと、一端が本体に接続され他端が前記手元ハンドルに接続されたホ−スを有し、前記ホ−スに絶縁被覆硬鋼線と合成樹脂製補強線を螺旋状に配し、前記絶縁被覆硬鋼線と前記制御回路とを電気的に接続するため、硬鋼線の使用量が半減でき、軽く出来るものである。
【0012】
本発明の請求項4記載の発明は、合成樹脂製補強線を中空とすることにより、樹脂量を削減し、さらに軽量化を促進するものである。
【0013】
【実施例】
(実施例1)
以下本発明の第1の実施例を、図1〜図2を用いて説明する。
【0014】
図2は掃除機の全体を示すもので、吸引用の電動送風機(図示せず)を内蔵した電気掃除機本体1の吸気口1aにホ−ス2の一端を接続し、その他端には、前記電動送風機の運転をコントロ−ルする制御回路(図示せず)を内蔵した手元ハンドル3が接続されている。
【0015】
回転ブラシ(図示せず)または自走車輪(図示せず)を駆動する電動機(図示せず)を内蔵する床ノズル4と手元ハンドル3は、延長管5で連結されている。図1に示すように、前記ホ−ス2の内部には、通電用並びにホース2の補強を兼ねる補強線として、2種類の被覆補強線A6(絶縁被覆硬鋼線に相当)及び被覆補強線B7(絶縁被覆硬鋼線に相当)が所定の間隔を保って、各2条づつ、合計4条が螺旋状に配設され、さらにその上が外皮テ−プ8で覆われている。
【0016】
前記被覆補強線A6並びにB7は、それぞれ硬鋼線a9、径小硬鋼線b10と、それらを覆う樹脂などから成る硬鋼線被覆11で形成されている。そして径小硬鋼線b10の径は、硬鋼線a9に比較して径小に形成されている。
【0017】
前記被覆補強線A6及び被覆補強線B7は交互に配され、さらに所要電流値に対応して、被覆補強線A6を床ノズル4に、被覆補強線B7を制御回路にそれぞれ接続している。
【0018】
なお径小硬鋼線b10を用いた分、強度が弱くなるが、硬鋼線絶縁被覆11の硬度や材質により強度を補っている。
【0019】
上記構成による作用は以下の通りである。
【0020】
被覆補強線A6及び被覆補強線B7の硬鋼線a及び径小硬鋼線b10を用いるため、径を細くした硬鋼線b10の質量差分ホ−ス2が軽く出来るものであり操作性が向上するものである。
【0021】
又、床ノズル4が電動機を有しない一般の床ノズルの場合、前記電動機への電源供給は不要になり、導電線は信号のやりとり用に2本だけでよい。この際、被覆補強線A6及びB7のそれぞれ1本を制御回路に電気的に接続するようにすると、被覆補強線A6の硬鋼線a9が被覆補強線B7の硬鋼線b10より太いので、両方に細い硬鋼線b10を有する被覆補強線B7を用いるよりも、ホース2の保形強度が高められる効果もある。
【0022】
(実施例2)
次に本発明の第2の実施例を、図3を用いて説明する。なお上記第1の実施例と同一構成部品については同一符号を付して、その説明を省略する。
【0023】
床ノズルを使用しない掃除機の場合は、導電線は2本のみで良い。それを、図に示すように、導電線兼用の被覆補強線12(絶縁被覆硬鋼線に相当)と合成樹脂製補強線13を、2条づつ、合計4条を、交互に所定の間隔を保って螺旋状に配するものである。合成樹脂製補強線13の強度については、材質及び硬度にて被覆補強線12とのバランスを確保している。
【0024】
上記構成による作用は以下の通りである。
【0025】
4条の補強線のうち2条を合成樹脂製補強線13を用いるため硬鋼線の使用量が半減でき、ホ−ス2の質量を軽く出来るものであり、操作性が向上するものである。
【0026】
(実施例3)
次に本発明の第3の実施例を、図4を用いて説明する。本実施例は、上記第2の実施例で用いた合成樹脂製補強線13に中空部14を設けたもので、合成樹脂製補強線13に中空部14を設けることにより、断面形状による断面係数が向上し、曲げ応力が向上するとともに樹脂量を削減し軽量化を促進するものである。
【0027】
【発明の効果】
本発明の請求項1及び2記載の発明によれば、複数の硬鋼線の1本以上を細くできるため、ホ−スの質量の軽減が行え、操作性の良い電気掃除機を提供出来るものである。
【0028】
本発明の請求項3記載の発明によれば、合成樹脂製補強線を用いることにより、硬鋼線の使用量が低減でき、ホ−スの質量の軽減が行え、操作性の良い電気掃除機を提供出来るものである。
【0029】
本発明の請求項4記載の発明によれば、合成樹脂製補強線に中空部を設けることにより、合成樹脂製補強線の強度UPと、ホ−スの質量の軽減が行え、操作性の良い電気掃除機を提供出来るものである。

【Example】
(Example 1)
Hereinafter, the first embodiment of the present invention will be described with reference to FIGS. 1 and 2.
0014.
FIG. 2 shows the entire vacuum cleaner. One end of the hose 2 is connected to the intake port 1a of the electric vacuum cleaner main body 1 having a built-in electric blower for suction (not shown), and the other end is connected to the other end. A hand handle 3 having a built-in control circuit (not shown) for controlling the operation of the electric blower is connected.
0015.
The floor nozzle 4 containing the electric motor (not shown) for driving the rotating brush (not shown) or the self-propelled wheel (not shown) and the hand handle 3 are connected by an extension pipe 5. As shown in FIG. 1, inside the hose 2, two types of covering reinforcing wires A6 (corresponding to insulating coated hard steel wires) and covering reinforcing wires are used as reinforcing wires for energizing and reinforcing the hose 2. B7 (corresponding to an insulating coated hard steel wire) is arranged in a spiral shape with two rows each at a predetermined interval, and a total of four strips are spirally arranged, and the outer skin tape 8 covers the top thereof.
0016.
The covering reinforcing wires A6 and B7 are formed of a hard steel wire coating 11 made of a hard steel wire a9, a small diameter hard steel wire b10, and a resin or the like covering them, respectively. The diameter of the small-diameter hard steel wire b10 is smaller than that of the hard steel wire a9.
[0017]
The covering reinforcing wire A6 and the covering reinforcing wire B7 are arranged alternately, and the covering reinforcing wire A6 is connected to the floor nozzle 4 and the covering reinforcing wire B7 is connected to the control circuit corresponding to the required current value.
0018
Although the strength is weakened by the amount of the small diameter hard steel wire b10 used, the strength is supplemented by the hardness and material of the hard steel wire insulating coating 11.
0019
The action of the above configuration is as follows.
0020
Since the use of hard steel wire a 9 and a small diameter hard steel wire b10 coating reinforcing wires A6 and coated reinforcing wire B7, weight difference ho hard steel wire b10 that reduce the diameter - are those scan 2 can lightly operability It will improve.
0021.
Further, when the floor nozzle 4 is a general floor nozzle having no electric motor, it is not necessary to supply power to the electric motor, and only two conductive wires are required for exchanging signals. At this time, if one of each of the covering reinforcing wires A6 and B7 is electrically connected to the control circuit, the hard steel wire a9 of the covering reinforcing wire A6 is thicker than the hard steel wire b10 of the covering reinforcing wire B7. There is also an effect that the shape-retaining strength of the hose 2 is enhanced as compared with the case of using the covering reinforcing wire B7 having the thin hard steel wire b10.

In the case of a vacuum cleaner that does not use a floor nozzle, only two conductive wires are required. As shown in the figure, the coated reinforcing wire 12 (corresponding to the insulating coated hard steel wire) that also serves as the conductive wire and the synthetic resin reinforcing wire 13 are provided in two rows each, for a total of four strips, alternately at predetermined intervals. It is kept and arranged in a spiral shape. Regarding the strength of the synthetic resin reinforcing wire 13, the balance with the covering reinforcing wire 12 is ensured in terms of material and hardness.
