Description
本発明は、清掃具に関し、特に、清掃ロールを有する清掃ヘッドと、清掃ヘッドの上面部中央部分に連結されたハンドル部とを備える清掃具に関する。 The present invention relates to a cleaning tool, and more particularly to a cleaning tool including a cleaning head having a cleaning roll and a handle portion connected to a central portion of an upper surface portion of the cleaning head.
床面等の被清掃面を簡易に清掃できるようにする清掃具として、清掃ヘッドと、清掃ヘッドの上面部中央部分に連結されたハンドル部とを備え、清掃ヘッドに清掃シートを装着した状態で、ハンドル部を把持して清掃ヘッドを被清掃面に沿ってスライド移動させることにより、被清掃面を払拭して、清掃シートに汚れやほこりなどを付着させる清掃具が知られている（例えば、特許文献１参照）。 As a cleaning tool that makes it easy to clean the surface to be cleaned, such as the floor surface, it has a cleaning head and a handle connected to the center of the upper surface of the cleaning head, with a cleaning sheet attached to the cleaning head. A cleaning tool is known that grips the handle portion and slides the cleaning head along the surface to be cleaned, thereby wiping the surface to be cleaned and attaching dirt or dust to the cleaning sheet (for example, Patent Document 1).
また、特許文献１の清掃具では、汚れやほこりを容易に付着さることができるが、パンくずや砂などの粒状のゴミを付着することが困難な場合があることから、電動で駆動する回転ブラシを設けて、これらのゴミを、回転ブラシによってゴミ収容部に取り込むことで除去できるようにした掃除機も開発されている（例えば、特許文献２参照）。 Moreover, in the cleaning tool of patent document 1, although dirt and dust can adhere easily, since it may be difficult to adhere granular garbage, such as bread crumbs and sand, rotation driven electrically There has also been developed a vacuum cleaner provided with a brush so that these dusts can be removed by taking them into a dust container with a rotating brush (see, for example, Patent Document 2).
さらに、特許文献２の掃除機では、回転ブラシを電動で駆動させる機構が複雑になることから、清掃ヘッドを被清掃面に沿って清掃方向にスライド移動させる際に、被清掃面に接触することで生じる摩擦力によって回転可能な清掃ロールを、清掃ヘッドに取り付けておくことで、複雑な駆動機構を要することなく、この清掃ロールの回転によって、ゴミをゴミ収容部に取り込んで除去できるようにした清掃具も開発されている（例えば、特許文献３参照）。 Furthermore, in the cleaner of Patent Document 2, since the mechanism for electrically driving the rotating brush is complicated, when the cleaning head is slid along the surface to be cleaned in the cleaning direction, the surface to be cleaned is brought into contact. By attaching a cleaning roll that can be rotated by the friction force generated in the cleaning head to the cleaning head, the cleaning roll can be rotated so that dust can be taken in and removed by the rotation of the cleaning roll. A cleaning tool has also been developed (see, for example, Patent Document 3).
特許文献３の清掃具は、清掃ロールを被清掃面に接触させることで生じる摩擦力により、清掃ヘッドを清掃方向にスライド移動させるのに伴って、清掃ロールを自動的に回転させるようになっており、簡易な構成でゴミを被清掃面から効率良く除去することが可能であるが、その一方で、清掃ヘッドのスライド移動に伴って、清掃ロールが、ゴミを取り込む回転方向とは反対方向に回転すると、この清掃ロールの反対方向の回転によって、ゴミ収容部に取り込んだゴミを排出してしまう場合がある。このため、清掃ロールの反対方向の回転によるゴミの排出を回避できるようにする、新たな技術の開発が望まれている。 The cleaning tool of Patent Document 3 automatically rotates the cleaning roll as the cleaning head is slid in the cleaning direction by the frictional force generated by bringing the cleaning roll into contact with the surface to be cleaned. It is possible to efficiently remove dust from the surface to be cleaned with a simple configuration, but on the other hand, as the cleaning head slides, the cleaning roll moves in a direction opposite to the rotational direction in which the dust is taken in. When it rotates, the dust taken into the dust container may be discharged due to the rotation of the cleaning roll in the opposite direction. For this reason, the development of a new technique that can avoid the discharge of dust due to the rotation of the cleaning roll in the opposite direction is desired.
本発明は、清掃ヘッドを被清掃面に沿って清掃方向にスライド移動させる際に、清掃ロールがゴミを取り込む回転方向とは反対方向に回転しないようにして、ゴミ収容部に取り込んだゴミが排出されるのを効果的に回避することのできる清掃具を提供することを目的とする。 In the present invention, when the cleaning head is slid in the cleaning direction along the surface to be cleaned, the cleaning roll does not rotate in the direction opposite to the rotation direction in which the dust is taken in. It is an object of the present invention to provide a cleaning tool capable of effectively avoiding being done.
本発明は、清掃ロールを有する清掃ヘッドと、該清掃ヘッドの上面部の中央部分に回転可能に連結されたハンドル部とを備え、前記ハンドル部を把持して、前記清掃ヘッドを被清掃面に沿って清掃方向にスライド移動させることで、前記清掃ロールによって被清掃面上のゴミを前記清掃ヘッドの内部のゴミ収容部に捕集することが可能な清掃具であって、前記清掃ロールは、前記清掃方向の一方の側の領域の下面部に臨んで設けられており、前記清掃ヘッドの下面部における、前記清掃方向の前記清掃ロールとは反対側の他方の側の領域を覆って、清掃シートが着脱可能に装着されており、前記清掃ヘッドの下面部には、前記清掃方向と垂直な横方向から視て、下方に凸となった湾曲凸面が形成されている清掃具を提供することにより、上記目的を達成したものである。 The present invention includes a cleaning head having a cleaning roll and a handle portion rotatably connected to a central portion of the upper surface portion of the cleaning head, and grips the handle portion so that the cleaning head is placed on a surface to be cleaned. The cleaning roll is capable of collecting the dust on the surface to be cleaned by the cleaning roll in the dust container inside the cleaning head by sliding along the cleaning direction along the cleaning roll, It is provided facing the lower surface of the region on one side in the cleaning direction, and covers the region on the other side of the lower surface of the cleaning head opposite to the cleaning roll in the cleaning direction. Provided is a cleaning tool in which a sheet is detachably mounted, and a curved convex surface that is convex downward is formed on a lower surface portion of the cleaning head as viewed from a lateral direction perpendicular to the cleaning direction. By the above It is those that have achieved the target.
本発明の清掃具によれば、複雑な構造を要することなく、清掃ヘッドを被清掃面に沿って清掃方向にスライド移動させる際に、清掃ロールがゴミを取り込む回転方向とは反対方向に回転しないようにして、ゴミ収容部に取り込んだゴミが排出されるのを効果的に回避することができる。 According to the cleaning tool of the present invention, when the cleaning head is slid in the cleaning direction along the surface to be cleaned without requiring a complicated structure, the cleaning roll does not rotate in the direction opposite to the rotation direction for taking in the dust. In this way, it is possible to effectively avoid the dust taken into the dust container from being discharged.
図１に示す本発明の好ましい一実施形態に係る清掃具１０は、例えば床面を被清掃面５０として払拭する清掃作業を行う際に用いられる。本実施形態の清掃具１０は、ハンドル部１２の柄部１２ａを把持して、好ましくは清掃ヘッド１１を被清掃面５０に沿って清掃方向Ｘの前方側Ｘ’にスライド移動させることで、清掃ヘッド１１に装着された清掃シート１３によって、主として汚れやほこりを被清掃面５０から除去できるようになっている（図７（ｂ）参照）。また、好ましくは清掃ヘッド１１を水平方向に１８０°回転させることにより反転させて、清掃方向Ｘの前方側Ｘ’にスライド移動させることで、好ましくは清掃シート１３による毛、ほこり等のゴミ、また汚れの除去を引き続き行いながら、清掃ヘッド１１に取着された清掃ロール１４（図２参照）によって、主としてパンくずや砂などの粒状のゴミを、被清掃面５０から除去できるようになっている（図７（ｃ）参照）。本実施形態の清掃具１０は、清掃ヘッド１１に取着された清掃ロール１４が、粒状のゴミを取り込む回転方向とは反対の方向に回転しないようにして、取り込んだ粒状のゴミが排出されるのを防止する機能を備えている。このように、本実施形態の清掃具１０では、毛、ほこり等のゴミだけでなく、パンくず、米、菓子くず、砂等の粒ゴミまで除去することが可能となる。 A cleaning tool 10 according to a preferred embodiment of the present invention shown in FIG. 1 is used, for example, when performing a cleaning operation for wiping the floor surface as a surface to be cleaned 50.

This also allows particulate dust on the surface to be cleaned 50 to be taken into the dust container 16 by the cleaning roll 14 and efficiently removed while preferably removing dirt and dust with the cleaning sheet 13. At the same time, the portion of the cleaning sheet 13 covering the curved convex surface 17 can efficiently remove dirt and dust on the surface to be cleaned 50.
さらに、清掃ヘッド１１を再度水平方向に１８０°回転させることにより反転させて、清掃ロール１４とは反対側である、清掃方向Ｘの他方の側を前方側Ｘ’としてスライド移動させれば、図７（ｂ）に示すように、清掃ヘッド１１は、清掃方向Ｘの他方の側（前方側Ｘ’）に傾くことで、清掃ロール１４の下端部分を被清掃面５０から離間させて、清掃ロール１４が回転しないようにすることが可能になると共に、清掃ヘッド１１の下面部１１ｂの、清掃ロール１４とは反対側の領域を覆う部分の清掃シート１３によって、被清掃面５０上のほこり、毛等のゴミ、または汚れを効率良く除去することが可能になる。 Further, if the cleaning head 11 is reversed by rotating it 180 ° in the horizontal direction again, the other side of the cleaning direction X, which is the opposite side of the cleaning roll 14, is slid and moved as the front side X ′. 7 (b), the cleaning head 11 is inclined to the other side (front side X ′) in the cleaning direction X, so that the lower end portion of the cleaning roll 14 is separated from the surface to be cleaned 50, and the cleaning roll 14 can be prevented from rotating, and dust and hair on the surface to be cleaned 50 are covered by the cleaning sheet 13 that covers the area of the lower surface 11b of the cleaning head 11 opposite to the cleaning roll 14. It is possible to efficiently remove dust such as dirt.
これらによって、本実施形態の清掃具１０によれば、清掃ヘッド１１を被清掃面５０に沿って清掃方向Ｘにスライド移動させる際に、清掃ヘッド１１に取着された清掃ロール１４が、粒状のゴミを取り込む回転方向Ｙとは反対方向に回転しないようにして、ゴミ収容部１６に取り込んだ粒状のゴミがゴミ収容部１６から排出されるのを、効果的に回避することが可能になる。 Thus, according to the cleaning tool 10 of the present embodiment, when the cleaning head 11 is slid in the cleaning direction X along the surface to be cleaned 50, the cleaning roll 14 attached to the cleaning head 11 is granular. It is possible to effectively prevent the particulate dust taken into the dust container 16 from being discharged from the dust container 16 so as not to rotate in the direction opposite to the rotation direction Y for taking in the dust.
また、本実施形態の清掃具１０によれば、清掃ヘッド１１の下面部１１ｂにおける、清掃ロール１４とは反対側の、湾曲凸面１７を挟んだ清掃方向Ｘの他方の側の領域に、平坦な当接平坦面２３が形成されている。これによって、図７（ｂ）に示すように、清掃ヘッド１１を清掃方向Ｘの他方の側を前方側Ｘ’としてスライド移動させながら被清掃面５０を払拭する際に、清掃ヘッド１１が清掃方向Ｘの前方側Ｘ’に傾き過ぎることになるのを、広い当接面積を備える平坦な当接平坦面２３を介して下面部１１ｂを被清掃面５０に当接させることにより効果的に抑制して、より安定した状態で、清掃ロール１４とは反対側の領域を覆う部分の清掃シート１３によって、被清掃面５０上の汚れやほこりを除去することが可能になる。 Further, according to the cleaning tool 10 of the present embodiment, a flat surface is formed on the lower surface portion 11b of the cleaning head 11 on the other side in the cleaning direction X across the curved convex surface 17 on the side opposite to the cleaning roll 14. A flat contact surface 23 is formed. Thus, as shown in FIG. 7B, when the cleaning head 11 is wiped on the surface to be cleaned 50 while sliding the cleaning head 11 with the other side of the cleaning direction X as the front side X ′, the cleaning head 11 is in the cleaning direction. It is possible to effectively suppress the inclination to the front side X ′ of X by bringing the lower surface portion 11b into contact with the surface to be cleaned 50 via the flat contact flat surface 23 having a wide contact area. Thus, in a more stable state, dirt and dust on the surface to be cleaned 50 can be removed by the portion of the cleaning sheet 13 that covers the area opposite to the cleaning roll 14.
なお、本発明は上記実施形態に限定されることなく種々の変更が可能である。例えば、清掃ヘッドは、矩形の平面形状を備えている必要は必ずしも無く、長円形状や楕円形状等の、その他の種々の平面形状を備えていても良い。清掃ヘッドは、合成樹脂の他、木材やウレタン等を用いて形成することもできる。清掃ロールは、清掃ヘッドの下面部における、清掃方向の一方の側の領域に、清掃方向と垂直な方向の全長に亘って連続して設けられている必要は必ずしも無く、粒状のゴミを除去するのに適した部分のみに、清掃ロールを設けることもできる。清掃ロールは、連続させることなく、分断させた状態で設けることもできる。清掃ロールは、回転軸部の外周面にスポンジロールを取り付けたものの他、ブラシ等を取り付けたものであっても良い。 The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the cleaning head does not necessarily have a rectangular planar shape, and may have various other planar shapes such as an oval shape and an elliptical shape. The cleaning head can be formed using wood, urethane or the like in addition to synthetic resin. The cleaning roll does not necessarily need to be continuously provided over the entire length in the direction perpendicular to the cleaning direction in the region on one side of the cleaning direction on the lower surface of the cleaning head, and removes granular dust. It is also possible to provide a cleaning roll only in a part suitable for the above. The cleaning roll can also be provided in a separated state without being continuous. The cleaning roll may be provided with a brush or the like in addition to the sponge roll attached to the outer peripheral surface of the rotating shaft portion.
また、清掃シートは、袋状係着部を備えるものである必要は必ずしも無く、公知の各種の係着手段を用いて、清掃ロールを覆わない状態で清掃シートを取り付けても良い。清掃シートの係着部は、下面部の他、側面部や縁部（上面側接合片２０ｃや下面側接合片２１ｃ）に設けることもできる。上面部に設けても良い。さらに、図７（ａ）に示す清掃ヘッドを被清掃面から僅かに浮かせた状態で、例えば清掃ヘッドが清掃方向の一方の側に傾くように、清掃ヘッドの重心の位置を調整しておくこともできる。これによって、清掃ヘッドを清掃方向の一方の側にスライド移動させて、粒状のゴミを取り除く際の操作性を、向上させることが可能になる。このような重心の位置の調整は、例えば清掃ヘッドとハンドル部との連結位置を移動させることによって行うことができる。例えば、清掃ヘッドに取り付けられる清掃ロールが重い場合には、清掃ヘッドの清掃方向へのスライド移動時に、清掃ロールが被清掃面から容易に離間できるように、清掃ロールとは反対の縁部側（上面側接合片２０ｃや下面側接合片２１ｃの側）に連結位置を移動させて、重心の位置を調整することが好ましい。 Moreover, the cleaning sheet does not necessarily need to be provided with a bag-like engaging portion, and the cleaning sheet may be attached in a state where the cleaning roll is not covered using various known engaging means. The engaging portion of the cleaning sheet can be provided on the side surface portion or the edge portion (upper surface side bonding piece 20c or lower surface side bonding piece 21c) in addition to the lower surface portion. You may provide in an upper surface part. Furthermore, the position of the center of gravity of the cleaning head is adjusted so that the cleaning head is tilted to one side in the cleaning direction, for example, with the cleaning head shown in FIG. You can also. This makes it possible to improve operability when the cleaning head is slid to one side in the cleaning direction to remove granular dust. Such adjustment of the position of the center of gravity can be performed, for example, by moving the connecting position between the cleaning head and the handle portion. For example, when the cleaning roll attached to the cleaning head is heavy, the edge side opposite to the cleaning roll (so that the cleaning roll can be easily separated from the surface to be cleaned when the cleaning head slides in the cleaning direction) It is preferable to adjust the position of the center of gravity by moving the connection position to the upper surface side joining piece 20c and the lower surface side joining piece 21c side).
