Description

本発明は清掃具に関する。 The present invention relates to a cleaning tool.

清掃具として、特許文献１に記載の如く、ブラシ体をフレームに回動自在に支持し、ブラシ体の前後両側に塵埃収納部（ダストルーム）を設けたものがある。
特公昭55-46189号公報 As a cleaning tool, there is a cleaning tool in which a brush body is rotatably supported on a frame and a dust storage part (dust room) is provided on both front and rear sides of the brush body, as described in Patent Document 1.
Japanese Patent Publication No.55-46189

ブラシ体が床面上から掻き飛ばす塵埃がその後方の塵埃収納部に投入されず、塵埃収納部と床面との隙間を後方にすり抜けてしまうことがあり、集塵性能が悪い。 The dust scraped off from the floor surface by the brush body is not thrown into the dust storage portion behind the brush body, and may pass through the gap between the dust storage portion and the floor surface, resulting in poor dust collection performance.

本発明の課題は、掻き上げ体が掻き飛ばす塵埃を塵取部により確実に捕捉し、集塵性能を向上することにある。 SUMMARY OF THE INVENTION An object of the present invention is to reliably capture dust that is scraped off by a scraping body by a dust collector and improve dust collection performance.

請求項１の発明は、掻き上げ体をフレームに回動自在に支持し、掻き上げ体の後部に配置される塵取部をフレームに支持してなる清掃具であって、塵取部は掻き上げ体が掻き上げる塵埃をガイドするすくい面部と、すくい面部と鋭角をなして連設する底面部を備え、塵取部は底面部の平坦面を略全体的に床面に接した状態を保ちながらフレームに対して上下動自在に支持されてなるようにしたものである。 The invention of claim 1 is a cleaning tool in which the scraping body is rotatably supported by the frame, and the dust collector disposed at the rear of the scraper is supported by the frame. It has a rake face that guides the dust that the raised body scrapes, and a bottom face that is connected to the rake face at an acute angle. The dust collector keeps the flat surface of the bottom face almost in contact with the floor. However, it is supported so as to be movable up and down with respect to the frame.

清掃具１０は、フレーム１１の前部に回転軸１３を介してブラシからなる掻き上げ体１２を回動自在に支持し、フレーム１１の後部に回転軸１５を介して車輪１４を回動自在に支持する。 The cleaning tool 10 rotatably supports a scraping body 12 made of a brush on a front portion of a frame 11 via a rotation shaft 13 and enables a wheel 14 to rotate on a rear portion of the frame 11 via a rotation shaft 15. To support.

フレーム１１は、掻き上げ体１２の前方側に高さＨの塵埃導入口１６を設け、掻き上げ体１２の後方斜め上部に塵埃投入口１７を設け、この塵埃投入口１７に連なる塵埃収納室１８を備える。 In the frame 11, a dust introduction port 16 having a height H is provided on the front side of the scraping body 12, a dust introduction port 17 is provided on the rear upper part of the scraping body 12, and a dust storage chamber 18 connected to the dust introduction port 17. Is provided.

掻き上げ体１２は、掻き上げ部１２Ａ（ブラシ部）とタイヤ部１２Ｂからなり、掻き上げ部１２Ａの掻き上げ径（ブラシ径）をタイヤ部１２Ｂのタイヤ径より大きくしている。 The scraping body 12 includes a scraping portion 12A (brush portion) and a tire portion 12B, and the scraping diameter (brush diameter) of the scraping portion 12A is larger than the tire diameter of the tire portion 12B.

フレーム１１における掻き上げ体１２の後方側かつ塵埃投入口１７の下方側に塵取部２０を支持している。塵取部２０は、床面に接する底面部２０Ａと、掻き上げ体１２に隙間なく（又は隙間を介して）相対する曲面状（又は平面状）のすくい面部２０Ｂを有し、両側の平板状支軸部２０Ｃをフレーム１１の両側の矩形孔２１に上下動可能に支持している。塵取部２０は、支軸部２０Ｃを矩形孔２１に対し上下動し、自重により底面部２０Ａとすくい面部２０Ｂの最下端部を床面に隙間なく接し、掻き上げ体１２の掻き上げ部１２Ａが掻き飛ばす塵埃を床面に沿う後方に逃がすことなく、その全ての塵埃をすくい面部２０Ｂにより塵埃投入口１７の側にガイドする。 A dust collector 20 is supported on the rear side of the scraping body 12 in the frame 11 and on the lower side of the dust inlet 17. The dust collector 20 has a bottom surface portion 20A that is in contact with the floor surface, and a curved (or planar) rake face portion 20B that faces the scraping body 12 without a gap (or via the gap). The support shaft portion 20C is supported in the rectangular holes 21 on both sides of the frame 11 so as to be movable up and down. The dust collector 20 moves the support shaft 20C up and down with respect to the rectangular hole 21, and makes the bottom surface 20A and the bottom end of the scooping surface 20B come into contact with the floor without gaps due to its own weight. All the dust is guided to the dust input port 17 side by the scooping surface portion 20B without causing the dust to be scraped off to escape rearward along the floor surface.

清掃具１０は、フレーム１１の内面を塵埃導入口１６の側から掻き上げ体１２の斜め前方側の外周に沿って延在し、掻き上げ体１２の略直上部から分岐した分岐部１１Ａを掻き上げ体１２の斜め後方側の外周に沿って塵埃投入口１７の上縁形成部１１Ｂまで延在し、この上縁形成部１１Ｂを掻き上げ体１２の掻き上げ部１２Ａにつまった大型塵埃の掻き落とし部２２とする。 The cleaning tool 10 extends the inner surface of the frame 11 from the dust inlet 16 side along the outer periphery of the scraped body 12 obliquely forward, and scrapes the branch portion 11 </ b> A branched from the substantially upper part of the scraped body 12. Scraping large dust that extends to the upper edge forming portion 11B of the dust inlet 17 along the outer periphery of the raising body 12 on the diagonally rear side and clogs the upper edge forming portion 11B with the scraping portion 12A of the lifting body 12. The dropping unit 22 is assumed.

清掃具１０による清掃動作は以下の通りなされる。
(1)フレーム１１に設けた支持アーム（不図示）等に加える操作力により、清掃具１０を前進させることにより、掻き上げ体１２のタイヤ部１２Ｂを床面に押付けて回転させる。 The cleaning operation by the cleaning tool 10 is performed as follows.
(1) By moving the cleaning tool 10 forward by an operating force applied to a support arm (not shown) provided on the frame 11, the tire portion 12B of the scraping body 12 is pressed against the floor surface and rotated.

(2)掻き上げ体１２の掻き上げ部１２Ａが塵埃導入口１６から導入した床面上の塵埃を後方に掻き飛ばすと、この塵埃は塵取部２０のすくい面部２０Ｂにガイドされ、塵埃投入口１７から塵埃収納室１８に投入される。塵埃収納室１８に投入された塵埃は、不図示の排出口から排出される。 (2) When the scraping portion 12A of the scraping body 12 scrapes the dust on the floor surface introduced from the dust introduction port 16 backward, the dust is guided by the rake surface portion 20B of the dust collector 20 and becomes a dust input port. 17 is put into the dust storage chamber 18. The dust thrown into the dust storage chamber 18 is discharged from a discharge port (not shown).

尚、清掃具１０は、塵埃投入口１７又は塵埃収納室１８を電気掃除機の真空吸引口に接続して用いられるものであっても良い。 The cleaning tool 10 may be used by connecting the dust inlet 17 or the dust storage chamber 18 to the vacuum suction port of the electric vacuum cleaner.

また、清掃具１０の後進時に、塵取部２０の底面部２０Ａの尾端部が床面に引っ掛かることがないように、この尾端部をアール状に跳ね上げている。 Further, when the cleaning tool 10 moves backward, the tail end of the bottom surface portion 20A of the dust collector 20 is flipped up in a round shape so that the tail end is not caught on the floor surface.

本実施形態によれば、以下の作用がある。
(1)掻き上げ体１２が後方に掻き飛ばした床面上の塵埃は、塵取部２０のすくい面部２０Ｂにすくい上げられて捕捉され集塵効率を向上できる。すくい面部２０Ｂは床面に接しているから、塵埃をより後方へとすり逃がすことがない。 According to this embodiment, there are the following operations.
(1) The dust on the floor surface scraped off by the scraping body 12 is scooped up and captured by the scooping surface portion 20B of the dust collecting portion 20, and dust collection efficiency can be improved. Since the rake face portion 20B is in contact with the floor surface, the dust is not slipped further back.

(2)塵取部２０はフレーム１１に上下動自在に支持されているから、自重によって常に下向き移動習性を具備し、そのすくい面部２０Ｂを床面に隙間なく常に確実に当接せしめる。 (2) Since the dust collector 20 is supported by the frame 11 so as to be movable up and down, the dust collector 20 always has a downward movement behavior by its own weight, and the rake face 20B is always surely brought into contact with the floor without a gap.

(3)掻き上げ体１２がタイヤ部１２Ｂを備えるから、タイヤ部１２Ｂは清掃具１０の重量により床面に押付けられて回転し、掻き上げ体１２Ａを確実に回転させる。掻き上げ径をタイヤ径より大きくしたから、掻き上げ部１２Ａは弾性たわみの復元に基づく掻き上げ力により塵埃を強力に掻き上げ、掻き上げ性能を向上するし、カーペットの繊維の深い部分の塵埃も良く掻き出しできる。 (3) Since the scooping body 12 includes the tire portion 12B, the tire portion 12B is pressed against the floor surface by the weight of the cleaning tool 10 and rotates, thereby reliably rotating the scooping body 12A. Since the scraping diameter is made larger than the tire diameter, the scraping portion 12A strongly sweeps up the dust by the scraping force based on the restoration of the elastic deflection, improving the scraping performance, and dust in the carpet fiber deep part is also collected. Can scrape well.

(4)掻き上げ体１２の後方側にだけ塵取部２０を設け、塵取部２０を設けない前方側を塵埃導入口１６としたから、塵埃導入口１６は床面との間に大きな塵埃導入高さＨを形成し、菓子くず等の大きな塵埃もスムースに集塵できる。 (4) Since the dust removing portion 20 is provided only on the rear side of the scraping body 12, and the front side where the dust removing portion 20 is not provided is the dust introduction port 16, the dust introduction port 16 has a large amount of dust between the floor surface. An introduction height H is formed, and large dust such as confectionery waste can be collected smoothly.

本発明において、掻き上げ体は、ブラシに限らず、スポンジ、ゴムブレード、エラストマー、弾性突起体等でも良い。 In the present invention, the scraping body is not limited to a brush but may be a sponge, a rubber blade, an elastomer, an elastic protrusion, or the like.

また、本発明において、床面とは、畳、フローリング、カーペット等であり、特にフローリングに対し顕著で特有な効果を奏する。 In the present invention, the floor is a tatami mat, flooring, carpet or the like, and has a particularly remarkable and unique effect on flooring.
