Description

【0001】
【発明の属する技術分野】
本発明は、電気掃除機、特に、外部電力供給用の配線コードをリールで巻き取り可能とすると共に、その巻き取り操作をボタン操作によって自動的に行うようにした電気掃除機に関する。
【0002】
【従来の技術】
従来から、電気掃除機は、掃除機本体内に格納された電動送風機や掃除機本体に接続されるホース等に設置の電気設備に家庭用電源(外部電源)を供給するために配線コードを設けたものが知られている。
【0003】
また、この配線コードを掃除機本体内に収納可能とし、電気掃除機の使用時には掃除機本体から配線コードを引き出し、使用後には掃除機本体の上面に露出する操作ボタンカバーの押圧操作と一体に押し下げられる操作ボタンによって渦巻ばね等の巻取り力を駆動源とするリールが回転して配線コードを巻き取るようにしたものも知られている。
【0004】
ところで、このような配線コードの巻き取り操作を行うための操作ボタンカバーは掃除機本体の上面の任意位置に設けられている。
【0005】
しかしながら、掃除機本体の狭い上面には掃除機本体を持ち運ぶためのハンドル等が装備されることを考慮すると、巻取ボタンスイッチの設置位置や大きさが制限されるばかりでなく、掃除機本体の上面の意匠性も損なうという問題が生じていた。
【0006】
そこで、図4に示すように、掃除機本体1の重心位置Gを挟む位置で掃除機本体1を支持する略U字形状のハンドル2を設けると共に、掃除機本体1内の左右に電動送風機3とコード巻き取り用のリール4とを隣接して設け、ハンドル2の一方の脚部2aの下方に操作ボタン5を配置して、常時はハンドル2によって操作ボタン5を目隠しすると同時にハンドル2の握持部2bを格納位置よりもさらに下方へと押し下げることによってリール4が回転するように構成し、巻取ボタンスイッチを廃止すると共にコード巻き取り操作範囲を拡大することが考えられている(特開平6−46974号公報参照)。
【0007】
【発明が解決しようとする課題】
ところで、上記の如く構成された電気掃除機にあっては、操作ボタン5がハンドル2の一方の脚部2aの下方に配置されているため、通常操作されるハンドル2の中央部によって操作ボタン5を押圧操作した際の他方の脚部2aとの加重バランスが崩れやすく、ハンドル2の支持部やその周辺構造並びにハンドル2を厚肉とするなど、強度を確保する必要があるという問題が生じていた。
【0008】
また、掃除機本体1内の左右に電動送風機3とコード巻き取り用のリール4とを隣接して設けていることから、リール4の設置スペース確保のために電動送風機3が小型化して吸込力が低下するばかりでなく、電動送風機3の中心が掃除機本体1の左右中央からずれるために重心位置Gのずれが発生し、しかも、電動送風機3の中心が掃除機本体1の前方寄り左右中央に開口するホース接続開口1aの中心ともずれるために吸込効率が低下するといった不具合を解消する設計が面倒であるという問題が生じていた。
【0009】
本発明は、上記問題を解決するため、ハンドル並びにその周辺部の強度確保を抑えることができる電気掃除機を提供することを目的とする。
【0010】
【課題を解決するための手段】
その目的を達成するため、請求項1に記載の発明は、本体内の左右中央に設けられた電動送風機と、該電動送風機に外部電源を供給するための配線コードと、該配線コードを巻き取るリールと、該リールを回転させるリール駆動手段と、該リール駆動手段の駆動力に抗して前記リールの回転を停止させるリールストッパと、該リールストッパによる前記リールの回転停止状態を解除する操作ボタンと、前記本体の重心位置の上方で前記本体を支持すると共に常時は前記本体の上面形状に倣うように格納される可動式のハンドルとを備え、前記ハンドルの中央部下方で且つ前記本体の左右中央に前記操作ボタンを配置し
前記ハンドルを格納位置からさらに下方へと沈み込ませたとき、前記操作ボタンが操作されることを要旨とする。
【0011】
請求項1に記載の構成によれば、操作ボタンを押圧操作するための操作範囲をハンドルの表面と一致した広い操作範囲とすると同時に、そのハンドルの押圧操作に伴う操作加重がハンドルの左右中央に集中するため、加重バランスが良く、ハンドル並びにその周辺部の強度確保を少なくすることができる。
【0012】
請求項2に記載の発明は、前記ハンドルは略垂直方向に上下動することを要旨とする。
【0013】
請求項2に記載の構成によれば、本体を持ち運ぶためのハンドルばかりでなくリールの回転停止状態を解除する操作部分が本体重心位置に位置することから、配線コード巻き取り時の操作加重が本体重心位置と一致し、操作加重によって本体がぐらついたりすることがない。
【0014】
【発明の実施の形態】
次に、本発明の電気掃除機の実施の形態を図面に基づいて説明する。
【0015】
図2,図3において、符号11は電気掃除機(全体図省略)の掃除機本体(本体)である。掃除機本体11は、掃除機本体11の下方前後に跨る下カバー12と、掃除機本体11の上方位置してその前方から後方に順次隣接されたバンパー13,上前カバー14,上後カバー15と、上前カバー14の上方を開閉する蓋体16とを備え、これらによって掃除機本体11内に集塵室(図示せず)と電動機室17とを形成している。
【0016】
下カバー12の前方寄り底面には水平方向に旋回可能な前輪ホルダー18を介して回転可能に設けられた前輪19が設けられている。また、下カバー12の後方寄り左右側面には回転可能に後輪20が設けられている。尚、図3のPは前輪19からの加重を受けると共に前輪ホルダー18の回転中心である。
【0017】
バンパー13は、掃除機本体11の前方を保護するためのもので、その略中央には蓋体16を開放する際に押圧される開閉操作ボタン21が設けられている。上述した集塵室はこの蓋体16の下方に位置し、開閉操作ボタン21の押圧操作によって蓋体16が集塵室を開放してその集塵室内に着脱可能に設けられた集塵フィルター(図示せず)の交換が可能となっている。また、集塵室に連通すると共に吸引ホース(図示せず)が接続されるホース接続開口(図示せず)が上前カバー14の左右中央の前面に形成されている。
【0018】
上後カバー15の前方寄り上部にはハンドル収納部22が形成され、このハンドル収納部22には垂直方向に上下動可能なハンドル23が設けられている。また、上後カバー15の前方上部寄りには、ホルダー24が固定されている。
【0019】
ハンドル23は、掃除機本体11の重心Gの上方に握持部23aが位置すると共に、その握持部23aの両端には重心Gを挟む位置で掃除機本体11を支持する脚部23bが設けられている。また、握持部23aの前面にはハンドル収納部22の前壁22aに形成された突起22bと係合する凹部23cが形成されている。この凹部23cは上下方向に高さを有している。
【0020】
ホルダー24には掃除機本体11の重心位置Gの上方に位置して上方に向けて突出された突起24aが突出形成されている。突起24aには操作ボタン25が設けられいる。また、ホルダー24には支持ケース26が設けられている。
【0021】
支持ケース26には、振動吸収用の環状弾性部材27を介して電動送風機28が保持されている。また、支持ケース26には電動送風機28の外周面を覆うカバー部26aが形成されている。さらに、支持ケース26にはカバー部26aを離間状態で覆う横向き有底円筒状のモータカバー29が設けられている。
【0022】
モータカバー29とカバー部26aとは、電動送風機28で吸引した外気を吸引ホースに循環させる循環風路30を形成している。また、モータカバー29の底部には軸29aが後方に向けて突出されている。軸29aには配線コード(図示せず)を巻き取るリール31が回転可能に保持されている。また、軸29aは半割とされており、その半割部分で31を回転させるリール駆動手段としての渦巻ばね32の一端32aが保持されている。この渦巻ばね32の他端32bはリール31に固定されている。
【0023】
リール31は、上後カバー15に形成されたリブ15aと共同して電動送風機28を取り巻く環状の配線コード収納空間33を形成する巻取部31aと、この巻取部31aの外周縁部寄りから掃除機本体11の前方に向けて突出された環状リブ31bとが形成されている。また、リール31には配線コードの基端部と電気的に接続されてリール31の回転と一体に回転する回転接点部材34が保持されている。この回転接点部材34は、上後カバー15の内面に固定されると共に電動送風機28等の掃除機本体11に搭載された電気部品と接続された固定接点部材35と電気的に接続されている。
【0024】
一方、操作ボタン25は、その内部にコイルスプリング等の付勢部材(図示せず)が設けられている。この付勢部材はハンドル23が格納状態に有るときに握持部23aの底面に上端が弾接してハンドル23を押し上げ、凹部23cの下端と突起22bとの係合によりハンドル22が掃除機本体11の上面形状(上後カバー15の上面形状)に倣った格納位置を維持する。また、操作ボタン25には操作爪25aが一体に形成されている。
【0025】
この操作爪25aには、ホルダー24から突出された軸24bに回転可能に保持された軸36に固定の従動片37が当接している。
【0026】
この軸36には、図1(A)に示すように、ブラケット38を介して環状リブ31bに当接するローラ体39が設けられている。尚、軸36,従動片37,ブラケット38,ローラ体39は、図示を略する付勢部材によって常時はローラ体39が環状リブ31bに弾接するリールストッパを構成している。
【0027】
上記の構成において、電気掃除機を使用する場合、リール31に巻き取られた配線コードを引っ張ると、渦巻ばね32の付勢に抗してリール31が回転しつつ掃除機本体11から配線コードが引き出される。
【0028】
そして、所定の長さで配線コードの引出しを止めると、リールストッパの付勢部材によってローラ体39が環状リブ31bに弾接して渦巻ばね32の付勢に抗してリール31を停止させ、配線コードの不測な戻りを防止する。
【0029】
また、電気掃除機11を任意の場所に移動させる場合には、握持部23aを握ってハンドル23を上方に押し上げると、凹部23cと突起22bとの係合状態が解除され、図2の鎖線で示すように、ハンドル23が上方へと略垂直に変位して掃除機本体11の持ち運びが可能となる。
【0030】
この状態から、ハンドル23を再び格納状態とする場合や電気掃除機による清掃作業が終了した場合には、ハンドル23を下方に押し下げることにより、凹部23cと突起22bとが係合すると同時に操作ボタン25からの付勢により凹部23cの下端に突起22bが係合してハンドル23が格納状態となる。
【0031】
さらに、配線コードを巻き取り収納したい場合には、握持部23aの任意の位置を押し下げることにより、操作ボタン25が付勢に抗して押し下げられ、凹部23cの上端に突起22bが係合してハンドル23のそれ以上の下方変位が停止される。
【0032】
また、操作ボタン25が下方に押し下げられると、図1(B)に示すように、従動片37が軸36を回転させ、これによりローラ体39が環状リブ31bから離間して渦巻ばね32の復帰力を駆動源としてリール31が回転して配線コードを巻き取る。
【0033】
このように、操作ボタン25を重心位置Gの上方で且つハンドル23の左右中央に配置したことにより、ハンドル23を巻き取り操作手段として押圧操作した際の加重受けをハンドル23の中央とすることができ、加重受けバランスを良好に維持することができる。即ち、使用者が操作するハンドル23の握持部23aで直接操作ボタン25を押圧するので、ハンドル23の脚部23bには大きな強度を必要としない。
【0034】
また、ハンドル23を垂直方向の上下動式としたことにより、重心位置Gを挟む位置にある脚部23b間に握持部23aが位置し、ハンドル23を巻き取り操作手段として押圧操作した際の加重受けを重心位置近傍とすることができる。
【0035】
従って、図4で示したハンドル2と同様に、回動上下動式の構成で操作ボタン25を掃除機本体11の左右中心に配置した場合には、その操作ボタン25の配置位置が重心位置Gから掃除機本体11の後方に移動してしまい、巻き取り操作時の加重受けが重心からずれてしまうという不具合も解消される。
【0036】
しかも、掃除機本体11内の左右に電動送風機28とコード巻き取り用のリール31とが隣接して設けてはいないので、リール31の設置スペース確保のために電動送風機28が小型化して吸込力が低下するということがないばかりが、電動送風機28の中心を掃除機本体11の左右中央に略一致させているために掃除機本体11の左右何れか一方寄りに重心位置Gがずれるということもなく、さらに、電動送風機28の中心が掃除機本体11の前方寄り左右中央に開口するホース接続開口の中心ともずれないために吸込効率が低下するといった不具合も発生しない。
【0037】
【発明の効果】
以上説明したように、請求項1に記載の発明によれば、ハンドルの中央部下方で且つ本体の左右中央に操作ボタンを配置したことにより、操作ボタンを押圧操作するための操作範囲をハンドルの表面と一致した広い操作範囲とすると同時に、そのハンドルの押圧操作に伴う操作加重がハンドルの左右中央に集中するため、加重バランスが良く、ハンドル並びにその周辺部の強度確保を抑えることができる。
【0038】
請求項2に記載の発明によれば、ハンドルは略垂直方向に上下動することにより、配線コード巻き取り時の操作加重が本体重心位置と一致し、操作加重によって本体がぐらついたりすることがない。

BACKGROUND OF THE INVENTION
The present invention relates to an electric vacuum cleaner, and more particularly to an electric vacuum cleaner that can wind up a wiring cord for supplying external power with a reel and that automatically performs the winding operation by a button operation.
[0002]
[Prior art]
Conventionally, the vacuum cleaner has been provided with a wiring cord to supply household power (external power) to the electrical equipment installed in the electric blower stored in the vacuum cleaner body or a hose connected to the vacuum cleaner body. Is known.
[0003]
In addition, this wiring cord can be stored in the main body of the vacuum cleaner, and when using the vacuum cleaner, the wiring cord is pulled out from the main body of the vacuum cleaner, and after use, it is integrated with the pressing operation of the operation button cover exposed on the upper surface of the main body of the vacuum cleaner. There is also known one in which a reel having a winding force such as a spiral spring as a driving source is rotated by an operation button that is pushed down to wind a wiring cord.
[0004]
By the way, the operation button cover for performing the winding operation of the wiring cord is provided at an arbitrary position on the upper surface of the cleaner body.
[0005]
However, considering that the vacuum cleaner body is equipped with a handle for carrying the vacuum cleaner body, the installation position and size of the take-up button switch are not limited. There has been a problem that the design of the upper surface is also impaired.
[0006]
Therefore, as shown in FIG. 4, a substantially U-shaped handle 2 that supports the cleaner body 1 is provided at a position sandwiching the center of gravity G of the cleaner body 1, and the electric blower 3 is provided on the left and right sides of the cleaner body 1. And a reel 4 for winding the cord are provided adjacent to each other, and an operation button 5 is arranged below one leg 2a of the handle 2 so that the operation button 5 is always blindfolded by the handle 2 and at the same time the handle 2 is gripped. It is considered that the reel 4 is configured to rotate by pushing the holding portion 2b further downward from the storage position, thereby eliminating the winding button switch and expanding the cord winding operation range (Japanese Patent Laid-Open No. Hei. 6-46974).
[0007]
[Problems to be solved by the invention]
By the way, in the electric vacuum cleaner configured as described above, since the operation button 5 is disposed below one leg 2a of the handle 2, the operation button 5 is operated by the central portion of the handle 2 that is normally operated. The load balance with the other leg portion 2a when the button is pressed is easily lost, and there is a problem that it is necessary to ensure strength, such as the support portion of the handle 2 and its peripheral structure and the handle 2 being thick. It was.
[0008]
In addition, since the electric blower 3 and the reel 4 for winding the cord are provided adjacent to each other in the left and right sides of the cleaner body 1, the electric blower 3 is reduced in size and suction force to secure the installation space for the reel 4. In addition, the center of the electric blower 3 is displaced from the center of the left and right of the cleaner body 1, so that the center of gravity position G is shifted, and the center of the electric blower 3 is centered near the front of the cleaner body 1. There has been a problem that the design for solving the problem that the suction efficiency is lowered due to the deviation from the center of the hose connection opening 1a that opens in a complicated manner is troublesome.
[0009]
In order to solve the above-described problems, an object of the present invention is to provide a vacuum cleaner that can suppress the strength of the handle and the periphery thereof.
[0010]
[Means for Solving the Problems]
In order to achieve the object, an invention according to claim 1 is directed to an electric blower provided at the center of the left and right in the main body, a wiring cord for supplying an external power source to the electric blower, and winding up the wiring cord. Reel, reel driving means for rotating the reel, a reel stopper for stopping rotation of the reel against the driving force of the reel driving means, and an operation button for releasing the rotation stop state of the reel by the reel stopper When the constantly while supporting the body above the center of gravity of the body and a movable handle that is stored so as to follow the shape of the top surface of the body, left and right and the body at the central portion below the handle Place the operation button in the center ,
The gist is that the operation button is operated when the handle is further lowered from the retracted position .
[0011]
According to the configuration of the first aspect, the operation range for pressing the operation button is a wide operation range that matches the surface of the handle, and at the same time, the operation load accompanying the pressing operation of the handle is at the left and right center of the handle. Because it concentrates, the weighted balance is good, and the strength of the handle and the periphery thereof can be reduced.
[0012]
The gist of the invention described in claim 2 is that the handle moves up and down in a substantially vertical direction.
[0013]
According to the second aspect of the present invention, not only the handle for carrying the main body but also the operation portion for releasing the reel rotation stop state is located at the center of gravity of the main body. It coincides with the position of the center of gravity, and the body does not wobble due to operation load.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the electric vacuum cleaner of the present invention will be described based on the drawings.

A handle storage portion 22 is formed at the upper front portion of the upper rear cover 15, and a handle 23 that can move up and down in the vertical direction is provided in the handle storage portion 22. Further, a holder 24 is fixed near the front upper portion of the upper rear cover 15.
[0019]
The handle 23 has a gripping portion 23a located above the center of gravity G of the cleaner body 11, and both ends of the gripping portion 23a are provided with leg portions 23b that support the cleaner body 11 at positions sandwiching the center of gravity G. It has been. In addition, a recess 23c that engages with a protrusion 22b formed on the front wall 22a of the handle storage portion 22 is formed on the front surface of the gripping portion 23a. The recess 23c has a height in the vertical direction.
[0020]
The holder 24 is formed with a protrusion 24 a protruding above and located above the center of gravity G of the cleaner body 11. An operation button 25 is provided on the protrusion 24a. The holder 24 is provided with a support case 26.
[0021]
An electric blower 28 is held in the support case 26 via an annular elastic member 27 for absorbing vibration. The support case 26 is formed with a cover portion 26 a that covers the outer peripheral surface of the electric blower 28. Further, the support case 26 is provided with a laterally-bottomed cylindrical motor cover 29 that covers the cover portion 26a in a separated state.
[0022]
The motor cover 29 and the cover part 26a form a circulation air passage 30 that circulates outside air sucked by the electric blower 28 to the suction hose. Further, a shaft 29 a protrudes rearward from the bottom of the motor cover 29. A reel 31 for winding a wiring cord (not shown) is rotatably held on the shaft 29a. Further, the shaft 29a is divided in half, and one end 32a of a spiral spring 32 as a reel driving means for rotating 31 is held in the half portion. The other end 32 b of the spiral spring 32 is fixed to the reel 31.
[0023]
The reel 31 cooperates with a rib 15a formed on the upper rear cover 15 to form a winding portion 31a that forms an annular wiring cord storage space 33 that surrounds the electric blower 28, and from the vicinity of the outer peripheral edge of the winding portion 31a. An annular rib 31b protruding toward the front of the cleaner body 11 is formed. Further, the reel 31 holds a rotating contact member 34 that is electrically connected to the base end portion of the wiring cord and rotates integrally with the rotation of the reel 31. The rotary contact member 34 is fixed to the inner surface of the upper rear cover 15 and is electrically connected to a fixed contact member 35 connected to an electrical component mounted on the cleaner body 11 such as the electric blower 28.
[0024]
On the other hand, the operation button 25 is provided with an urging member (not shown) such as a coil spring. When the handle 23 is in the retracted state, the upper end of the urging member elastically contacts the bottom surface of the gripping portion 23a to push up the handle 23, and the handle 22 is brought into contact with the lower end of the recess 23c and the protrusion 22b. The storage position following the upper surface shape (the upper surface shape of the upper rear cover 15) is maintained. The operation button 25 is integrally formed with an operation claw 25a.
[0025]
A fixed driven piece 37 is in contact with the operating claw 25a on a shaft 36 rotatably held by a shaft 24b protruding from the holder 24.
[0026]
As shown in FIG. 1A, the shaft 36 is provided with a roller body 39 that comes into contact with the annular rib 31b via a bracket 38. The shaft 36, the follower piece 37, the bracket 38, and the roller body 39 constitute a reel stopper in which the roller body 39 is always in elastic contact with the annular rib 31b by a biasing member (not shown).
[0027]
In the above configuration, when a vacuum cleaner is used, when the wiring cord wound around the reel 31 is pulled, the reel 31 rotates against the bias of the spiral spring 32 and the wiring cord is rotated from the cleaner body 11. Pulled out.
[0028]
When the drawing of the wiring cord is stopped at a predetermined length, the roller body 39 is brought into elastic contact with the annular rib 31b by the biasing member of the reel stopper, and the reel 31 is stopped against the biasing of the spiral spring 32. Prevent inadvertent return of code.
[0029]
When the vacuum cleaner 11 is moved to an arbitrary location, when the handle 23a is gripped and the handle 23 is pushed upward, the engaged state between the recess 23c and the protrusion 22b is released, and the chain line in FIG. As shown, the handle 23 is displaced vertically upwards, so that the cleaner body 11 can be carried.
[0030]
From this state, when the handle 23 is returned to the retracted state or when the cleaning operation by the electric vacuum cleaner is completed, the operation button 25 is simultaneously engaged with the depression 23c and the projection 22b by pushing the handle 23 downward. The protrusion 22b engages with the lower end of the concave portion 23c by the urging force, and the handle 23 enters the retracted state.
[0031]
Furthermore, when it is desired to wind up and store the wiring cord, the operation button 25 is pushed down against the bias by pushing down an arbitrary position of the gripping portion 23a, and the projection 22b is engaged with the upper end of the recess 23c. Then, further downward displacement of the handle 23 is stopped.
[0032]
When the operation button 25 is pushed down, the driven piece 37 rotates the shaft 36 as shown in FIG. 1B, whereby the roller body 39 is separated from the annular rib 31b and the spiral spring 32 is returned. The reel 31 rotates using force as a driving source to wind up the wiring cord.
[0033]
Thus, by arranging the operation button 25 above the center of gravity G and at the center of the left and right of the handle 23, the weight receiver when the handle 23 is pressed as the winding operation means can be set to the center of the handle 23. And the weighted balance can be maintained well. That is, since the operation button 25 is directly pressed by the gripping portion 23a of the handle 23 operated by the user, the leg portion 23b of the handle 23 does not require great strength.
[0034]
In addition, since the handle 23 is vertically movable, the gripping portion 23a is positioned between the leg portions 23b located at the position where the center of gravity G is sandwiched, and when the handle 23 is pressed as a winding operation means, The weighted receiver can be set near the center of gravity.
[0035]
Therefore, in the same way as the handle 2 shown in FIG. 4, when the operation button 25 is arranged at the center of the left and right of the cleaner body 11 with a rotary up-and-down movement type configuration, the arrangement position of the operation button 25 is the center of gravity G The problem that the weight receiver during the winding operation is displaced from the center of gravity is also eliminated.
[0036]
Moreover, since the electric blower 28 and the reel 31 for winding the cord are not provided adjacent to each other in the left and right sides of the cleaner body 11, the electric blower 28 is reduced in size to secure the installation space for the reel 31, and the suction force However, since the center of the electric blower 28 is substantially coincident with the center of the left and right of the cleaner body 11, the center of gravity position G may be shifted to the left or right of the cleaner body 11. Furthermore, since the center of the electric blower 28 does not deviate from the center of the hose connection opening that opens to the front left and right of the cleaner body 11, there is no problem that the suction efficiency is lowered.
[0037]
【The invention's effect】
As described above, according to the first aspect of the present invention, the operation range for pressing the operation button is provided by arranging the operation button below the center of the handle and at the center of the left and right of the main body. At the same time as having a wide operation range that matches the surface, the operation load accompanying the pressing operation of the handle is concentrated in the center of the left and right of the handle, so that the load balance is good and the strength of the handle and its peripheral part can be suppressed.
[0038]
According to the second aspect of the present invention, the handle is moved up and down in a substantially vertical direction so that the operation load when winding the wiring cord coincides with the position of the center of gravity of the main body, and the main body does not wobble due to the operation load. .
