以下、図面に示す実施形態を用いてこの発明を詳述する。この実施形態によってこの発明が限定されるものではない。 Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. The present invention is not limited to the embodiments.

（第１実施形態）
図１は、この発明の電気掃除機の第１実施形態を示す外観斜視図である。 (First embodiment)
FIG. 1 is an external perspective view showing a first embodiment of the electric vacuum cleaner of the present invention.

〈電気掃除機の全体構成〉
図１に示すように、電気掃除機１は、掃除機本体２と、吸込口体４０と、吸込口体４０と掃除機本体２とを気密的に接続する接続管４とを備える。 <Overall configuration of electric vacuum cleaner>
As shown in FIG. 1, the vacuum cleaner 1 includes a cleaner body 2, a suction port body 40, and a connection pipe 4 that hermetically connects the suction port body 40 and the cleaner body 2.

掃除機本体２は、使用者が手で握るハンドル５と、ハンドル５に設けられ起動・停止スイッチを有する操作部６と、接続管４の基端を受け入れて離脱可能に接続する接続部７を備える。 The vacuum cleaner main body 2 includes a handle 5 that is gripped by a user, an operation unit 6 that is provided on the handle 5 and has a start / stop switch, and a connection unit 7 that receives the base end of the connection pipe 4 and removably connects it. Prepare.

接続管４の先端には、吸込口体４０の接続パイプ部４２を受け入れて離脱可能に接続する接続部９が設けられている。また、吸込口体４０は、接続パイプ部４２を吸込口体４０に対して、約９０度の角度範囲で前後に揺動させ、かつ、約１８０度の角度範囲で左右に捩じることが可能な関節式の接続軸部４２ｘを備える。 A connecting portion 9 is provided at the tip of the connecting pipe 4 to receive the connecting pipe portion 42 of the suction port body 40 and connect the connecting pipe portion 42 in a detachable manner. In addition, the suction port body 40 can swing the connecting pipe portion 42 back and forth with respect to the suction port body 40 in an angle range of about 90 degrees, and can be twisted left and right in an angle range of about 180 degrees. Possible joint-type connecting shaft part 42x is provided.

また、接続部９が図２の端部４１ｇに接触することで掃除機本体２の傾斜を制止している。その時に掃除機本体２が、略９０度に位置している状況になっている。その状態から吸込口体４０の長手方向に傾けるとき、端部４１ｇが滑らかな曲線を描いているため、電気掃除機本体２を傾けるときにスムーズに動作を行うことができる。 Moreover, the inclination of the cleaner main body 2 is restrained by the connection part 9 contacting the edge part 41g of FIG. At that time, the cleaner body 2 is located at approximately 90 degrees. When tilting in the longitudinal direction of the suction port body 40 from this state, since the end 41g draws a smooth curve, the operation can be performed smoothly when the vacuum cleaner body 2 is tilted.

また、接続パイプ部４２を略９０度傾斜して制止している状態では、接続パイプ部４２と端部４１ｇとが接触して、傷が付くため、接続パイプ４２側の接触部分に凸部４１ｈを設け、傷を目立たなくして、外観を損なわないようにしている。 Further, in a state where the connection pipe portion 42 is inclined and stopped by approximately 90 degrees, the connection pipe portion 42 and the end portion 41g come into contact with each other and are scratched. Therefore, the convex portion 41h is formed on the contact portion on the connection pipe 42 side. Is provided so that the scratches are not noticeable and the appearance is not impaired.

It is transmitted to the rotating brush body 45 through the support shaft 62. On the other hand, since the other end of the rotating brush 43 is supported by the recess 70 (FIG. 7) via the first bearing 60 and the first support shaft 59, the rotating brush 43 is securely held by the suction port body 40 and is stable. Can be rotated.

この実施形態の回転ブラシ４３は、上記のような構成を有し、吸込口体４０の内部に吸込口４１の位置に対応して設置されるが、右側板部４１ｆ側において第１軸受け６０が回転ブラシ本体４５の内部に設けられるため、回転ブラシ本体４５が右側板部４１ｆへ少なくとも第１軸受け６０の長さ分だけ接近することができる。従って、吸込口体４０の右側板部４１ｆ側を利用することにより、壁際や狭隘な場所での掃除の作業性が向上する。 The rotating brush 43 of this embodiment has the above-described configuration, and is installed inside the suction port body 40 corresponding to the position of the suction port 41, but the first bearing 60 is provided on the right side plate portion 41f side. Since the rotary brush main body 45 is provided inside the rotary brush main body 45, the rotary brush main body 45 can approach the right side plate portion 41f by at least the length of the first bearing 60. Therefore, by using the right side plate portion 41f side of the suction port body 40, the workability of cleaning at a wall side or in a narrow place is improved.

＜ブラシカバー部材の構成と使用方法＞
図１１および図１２に示すように、ブラシカバー部材８０は、底板部４１ａと後板部４１ｄとの間を底板部４１aに対して鋭角を有してつなぐ傾斜部８１と、傾斜部８１の内部に設けられ吸込口体４０に対してブラシカバー部材８０をロックするロック機構８２と、傾斜部８１の外面に設けられロック機構８２を開閉操作するスライド式の手動開閉レバー８３とを備える。 <Configuration and usage of brush cover member>
As shown in FIGS. 11 and 12, the brush cover member 80 includes an inclined portion 81 that connects the bottom plate portion 41a and the rear plate portion 41d with an acute angle with respect to the bottom plate portion 41a, and an interior of the inclined portion 81. A locking mechanism 82 that locks the brush cover member 80 with respect to the suction port body 40, and a slide-type manual opening / closing lever 83 that is provided on the outer surface of the inclined portion 81 and opens and closes the locking mechanism 82.

ブラシカバー部材８０は、主に、回転ブラシ４３の手入れや清掃などのメンテナンス時に取り外される。回転ブラシ４３のメンテナンス時には、先ず安全のため、バッテリー１７を掃除機本体２から取り外し、次に、ブラシカバー部材８０の手動開閉レバー８３を「開」の方向に操作してブラシカバー部材８０を吸込口体４０から取り外す。 The brush cover member 80 is mainly removed during maintenance such as maintenance and cleaning of the rotating brush 43. At the time of maintenance of the rotating brush 43, first, for safety, the battery 17 is removed from the cleaner body 2, and then the manual opening / closing lever 83 of the brush cover member 80 is operated in the “open” direction to suck the brush cover member 80. Remove from mouth 40.

次に、回転ブラシ４３の支軸保持部材６３を載置部７１から少し持ち上げ、タイミングベルト４８を回転ブラシ４３のギア部５８ｂから外したのち、回転ブラシ４３の第１支軸５９を右側板部４１ｆの受入れ凹部７０から抜き出し、回転ブラシ４３を吸込口４１から取り出す。 Next, after slightly lifting the support shaft holding member 63 of the rotating brush 43 from the mounting portion 71 and removing the timing belt 48 from the gear portion 58b of the rotating brush 43, the first support shaft 59 of the rotating brush 43 is moved to the right side plate portion. It is extracted from the receiving recess 70 of 41 f and the rotating brush 43 is extracted from the suction port 41.

そして、回転ブラシ４３や吸込口４１の周辺を清掃したのち、回転ブラシ４３の第１支軸５９を右側板部４１ｆの受入れ凹部７０（図７）に挿入し、タイミングベルト４８を回転ブラシ４３のギア部５８ｂに装着したのち、支軸保持部材６３を載置部７１（図７）に載置する。 Then, after cleaning the periphery of the rotary brush 43 and the suction port 41, the first support shaft 59 of the rotary brush 43 is inserted into the receiving recess 70 (FIG. 7) of the right side plate portion 41f, and the timing belt 48 is attached to the rotary brush 43. After mounting on the gear portion 58b, the support shaft holding member 63 is placed on the placement portion 71 (FIG. 7).

次に、ブラシカバー部材８０のツメ８４（図１１）を吸込口４１の溝（図示せず）に掛けてブラシカバー部材８０を底板部４１ａに取り付け、手動開閉レバー８３を「閉」の方向に操作し、ブラシカバー部材８０を底板部４１に固定する。ブラシカバー部材８０によって支軸保持部材６３が載置部７１に確実に固定され、回転ブラシ４３は安定して回転することができる。 Next, the tab 84 (FIG. 11) of the brush cover member 80 is hung on the groove (not shown) of the suction port 41, the brush cover member 80 is attached to the bottom plate portion 41a, and the manual opening / closing lever 83 is set in the “closed” direction. The brush cover member 80 is fixed to the bottom plate portion 41 by operating. The support shaft holding member 63 is securely fixed to the mounting portion 71 by the brush cover member 80, and the rotating brush 43 can rotate stably.

この実施形態のブラシカバー部材８０によれば、手動開閉レバー８３が底板部４１ａと後板部４１ｄとの間を底板部４１aに対して鋭角を有してつなぐ傾斜部８１に設けられるので、手動開閉レバー８３が底板部４１ａや左右側板部から突出することがなく、安全で、かつ、操作性に優れる。 According to the brush cover member 80 of this embodiment, the manual opening / closing lever 83 is provided in the inclined portion 81 that connects the bottom plate portion 41a and the rear plate portion 41d with an acute angle with respect to the bottom plate portion 41a. The open / close lever 83 does not protrude from the bottom plate portion 41a or the left and right side plate portions, and is safe and excellent in operability.

また、傾斜部８１を設けることで、吸込口体４０の底面と床面が接する範囲が少なくなり、吸込口体４０を移動する抵抗が減るので、掃除の作業が容易にできる。 In addition, by providing the inclined portion 81, a range where the bottom surface of the suction port body 40 and the floor surface are in contact with each other is reduced, and resistance to move the suction port body 40 is reduced.

また、吸込口体４０の底面に対し、回転ブラシ用モータ４４の軸（モータ出力軸４６）の位置を回転ブラシ４３の軸（第２支軸６２）の位置より少し上部へ配置することで、両者を水平に配置するときよりも吸込口体４０の短手側の幅を短くでき、吸込口体４０をコンパクトにすることができる。 In addition, by arranging the position of the shaft (motor output shaft 46) of the rotary brush motor 44 slightly above the position of the shaft (second support shaft 62) of the rotary brush 43 with respect to the bottom surface of the suction port body 40, The width on the short side of the suction port body 40 can be made shorter than when both are arranged horizontally, and the suction port body 40 can be made compact.

図１３は吸込口体４０の筐体を示す分解斜視図であり、同図（ａ），（ｂ）はそれぞれ上面および底面から見た斜視図である。これらの図において、底板部４１ａ、上部カバー部４１ｂａ、左側板部４１ｅ、右側板部４１ｆは一体の成型品で構成される。 FIG. 13 is an exploded perspective view showing the housing of the suction port body 40, and FIGS. 13A and 13B are perspective views seen from the top and bottom surfaces, respectively. In these drawings, the bottom plate portion 41a, the upper cover portion 41ba, the left side plate portion 41e, and the right side plate portion 41f are formed as an integral molded product.

そして、底板部４１ａと上部カバー部４１ｂａは、吸込口体４０の底面側と上面側の両方の壁面を成す部分を一つの部品で構成しているので、コンパクトにでき、組み立て作業も簡素化できる。この壁面及び左側板部４１ｅ、右側板部４１ｆは、外観を成している面でもある。また、吸込口体が、上側と下側のそれぞれの筐体を組み合わせて構成されるように筐体が分割している場合に比べて、筐体が一体で構成されている方が、筐体の強度の向上が図れる。また、この一体成型された成型品を透明または半透明な材料を使用することで、塵埃の捕集状況を目視により確認することができる。 And since the baseplate part 41a and the top cover part 41ba comprise the part which comprises the wall surface of both the bottom face side and the upper surface side of the suction inlet body 40 with one component, it can be made compact and an assembly operation can also be simplified. . The wall surface, the left side plate portion 41e, and the right side plate portion 41f are also surfaces forming an appearance. In addition, compared to the case where the casing is divided so that the suction port body is configured by combining the upper and lower casings, the casing is configured integrally. The strength of the can be improved. Further, by using a transparent or translucent material for the integrally molded product, it is possible to visually check the dust collection status.

なお、前板部４１ｃは、吸込口体４０が壁などに当たった場合の衝撃を和らげたり、傷が付くのを防止したりするもので、例えば、軟質性樹脂で作られた別部品で一体の成型品に取り付けすることができる。取り付けは、超音波溶着あるいは爪部を用いて嵌め込みで取り付けてよい。 The front plate portion 41c is for reducing the impact when the suction port body 40 hits a wall or the like, and preventing the front plate portion 41c from being damaged. For example, the front plate portion 41c is integrated with another part made of a soft resin. It can be attached to the molded product. The attachment may be performed by ultrasonic welding or fitting using a claw portion.

図１４は吸込口体４０の底面への起毛布の取り付けを示す説明図であり、同図（ａ）と（ｂ）はそれぞれ吸込口体４０に起毛布９２〜９４を取り付ける図と取り付けた後の図である。起毛布９２，９３は、それぞれ吸込口体４０の底面と側面と前面の３面に立体的にまたがる一つの部品で構成されている。また、起毛布９４はブラシカバー部材８０の平面部分に取り付けられる。
起毛布９２、９３の底面は、清掃面の床面などに傷が付くのを防止したり、側面は横壁に当たる際に傷を防止したり、前面は吸込口体４０が段差などを乗り越えるときに衝撃を和らげて、それらに傷が付くのを防止することができる。これらの目的のために、吸込口体４０の底面、側面、前面に対して、起毛布９２、９３を最少の部品、すなわち一つで構成することで、部品点数を減らし、製品コストを抑えることができ、取り付け作業も簡易になる。 FIG. 14 is an explanatory view showing the attachment of the raised cloth to the bottom surface of the suction port body 40. FIGS. 14A and 14B are views of attaching the raised cloth 92 to 94 to the suction port body 40, respectively. FIG. The raised fabrics 92 and 93 are each composed of a single part that three-dimensionally spans the bottom surface, the side surface, and the front surface of the suction port body 40. Further, the raised cloth 94 is attached to the flat portion of the brush cover member 80.
The bottom surfaces of the raised fabrics 92 and 93 prevent the floor surface of the cleaning surface from being scratched, the side surfaces prevent scratches when hitting the side walls, and the front surface is used when the suction port body 40 gets over a step or the like. It can soften the impact and prevent them from being scratched. For these purposes, it is possible to reduce the number of parts and reduce the product cost by configuring the brushed fabrics 92 and 93 with a minimum number of parts, that is, one, with respect to the bottom face, side face, and front face of the suction port body 40. And installation work is simplified.

また、起毛布９４により吸込口体４０が滑りやすくなり、移動が容易になる。なお、起毛布９２〜９４は、吸込口体４０に接着剤で貼り付けられる。 Further, the raised cloth 94 makes the suction port body 40 slippery and facilitates movement. In addition, the raising cloth 92-94 is affixed on the suction inlet 40 with an adhesive agent.
