Description

本発明は、電気掃除機用吸込口体の回転清掃体、それを備えた吸込口体および電気掃除機に関する。 The present invention relates to a rotary cleaning body for a suction port body for an electric vacuum cleaner, a suction port body provided with the rotary cleaning body, and an electric vacuum cleaner.

従来の電気掃除機の吸込口体として、特許文献１および２では、モータ駆動式の回転部材を備えた吸込口体が提案されている。
特許文献１および２の吸込口体において、回転部材は、外周部に２つの蟻溝が設けられた軸体と、軸体の２つの蟻溝に挿入された２つの清掃部材（ブレード）と、軸体の両端に設けられて軸方向外方へ突出する一対の軸芯と、一対の軸芯に一体回転可能に取り付けられたキャップ部材と、一対の軸芯に回転自在に取り付けられた軸受部材とを備える。 As a suction port body of a conventional vacuum cleaner, Patent Documents 1 and 2 propose a suction port body including a motor-driven rotating member.
In the suction port bodies of Patent Documents 1 and 2, the rotating members include a shaft body provided with two dovetail grooves on the outer peripheral portion, two cleaning members (blades) inserted into the two dovetail grooves of the shaft body, and the like. A pair of shaft cores provided at both ends of the shaft body and protruding outward in the axial direction, a cap member rotatably attached to the pair of shaft cores, and a bearing member rotatably attached to the pair of shaft cores. And.

特許文献１の吸込口体において、キャップ部材（端面板）は、外周部に設けられた２つの蟻溝（ブレード挿通部）と、軸体の端面と対向する端面に設けられた軸芯挿通孔と、端面において軸芯挿通孔の周囲に設けられた一対の位置決め体とを有している。この吸込口体によれば、キャップ部材を軸芯に対して周方向の一方向に回動することによりキャップ部材の各蟻溝の位置を軸体の各蟻溝からずらして清掃部材の抜け止めを行い、キャップ部材を他方向に回動することによりキャップ部材の各蟻溝の位置を軸体の各蟻溝に一致させて清掃部材の交換が可能となる。 In the suction port body of Patent Document 1, the cap member (end face plate) has two dovetail grooves (blade insertion portions) provided on the outer peripheral portion and a shaft core insertion hole provided on the end face facing the end face of the shaft body. And a pair of positioning bodies provided around the shaft core insertion hole on the end face. According to this suction port body, by rotating the cap member in one direction in the circumferential direction with respect to the shaft core, the position of each dovetail groove of the cap member is shifted from each dovetail groove of the shaft body to prevent the cleaning member from coming off. By rotating the cap member in the other direction, the positions of the dovetail grooves of the cap member are aligned with the dovetail grooves of the shaft body, and the cleaning member can be replaced.

特許文献２の吸込口体において、軸芯はキャップ部材（筒状部）の中心に固定されており、軸芯の軸体側の端部には雄ネジ部が設けられ、軸体の端部には雌ネジ部が設けられている。この吸込口体によれば、軸芯の雄ネジ部を軸体の雌ネジ部に螺合することによりキャップ部材にて清掃部材の抜け止めを行い、軸芯の雄ネジ部を軸体の雌ネジ部から離脱させることによりキャップ部材を軸体から取り外して清掃部材の交換が可能となる。 In the suction port body of Patent Document 2, the shaft core is fixed to the center of the cap member (cylindrical portion), a male screw portion is provided at the end portion of the shaft core on the shaft body side, and the end portion of the shaft body is provided. Is provided with a female screw portion. According to this suction port body, the male screw portion of the shaft core is screwed into the female screw portion of the shaft body to prevent the cleaning member from coming off with the cap member, and the male screw portion of the shaft core is the female of the shaft body. By separating from the screw portion, the cap member can be removed from the shaft body and the cleaning member can be replaced.

特許文献１の吸込口体では、清掃部材の数を３つ以上に増やす構造とすると、キャップ部材の外周部に設ける蟻溝の数を３つ以上に増やす必要があり、そうすると一対の位置決め体を設けるスペースが確保できなくなる。したがって、特許文献１の場合、清掃部材の数を３つ以上に増やすことが困難である。
特許文献２の吸込口体では、キャップ部材の軸芯を軸体に対して脱着する構造であるため、軸芯の脱着時に芯ぶれが生じやすくなり、その結果、回転体の駆動モータへの負荷増加、回転時の回転体による騒音増加等の弊害が起こり得る。 In the suction port body of Patent Document 1, if the number of cleaning members is increased to three or more, it is necessary to increase the number of dovetail grooves provided on the outer peripheral portion of the cap member to three or more. It becomes impossible to secure the space to be provided. Therefore, in the case of Patent Document 1, it is difficult to increase the number of cleaning members to three or more.
Since the suction port body of Patent Document 2 has a structure in which the shaft core of the cap member is attached to and detached from the shaft body, the core tends to be shaken when the shaft core is attached and detached, and as a result, the load on the drive motor of the rotating body is increased. There may be adverse effects such as an increase and an increase in noise due to the rotating body during rotation.

本発明は、このような事情を鑑みなされた電気掃除機用吸込口体の回転清掃体、それを備えた吸込口体および電気掃除機を提供することを目的とする。 An object of the present invention is to provide a rotary cleaning body for a suction port body for an electric vacuum cleaner, a suction port body provided with the rotary cleaning body, and an electric vacuum cleaner, which are made in view of such circumstances.

吸込口本体７１の筐体７２内において、吸込口７２ｂ側のスペースとプーリ・ベルト機構７５側のスペースは仕切り壁７２ｇによって区画されている。これにより、吸込口７２ｂ側のスペースに吸引されるダストがプーリ・ベルト機構７５側のスペースに侵入しにくくなっている。 In the housing 72 of the suction port main body 71, the space on the suction port 72b side and the space on the pulley / belt mechanism 75 side are partitioned by a partition wall 72g. As a result, the dust sucked into the space on the suction port 72b side is less likely to enter the space on the pulley / belt mechanism 75 side.

吸込口本体７１の筐体７２における吸込口７２ｂの左側には、回転清掃体７３の左側の軸受け部材７３ｄが嵌め込まれて保持されるためのリブ７２ｆが設けられている。また、筐体７２における吸込口７２ｂの右側には、回転清掃体７３の右側の軸受け部材７３ｄが嵌め込まれて保持されるためのリブ７２ｈが設けられている。これにより、プーリ・ベルト機構７５のプーリ７５ａが回転することにより、左側の芯部７３ａｃ、左側のキャップ体７３ａｂ、軸本体７３ａａ、右側のキャップ体７３ａｂおよび右側の芯部７３ａｃが回転する。このとき、左右の軸受け部材７３ｄは回転しない。 On the left side of the suction port 72b in the housing 72 of the suction port main body 71, a rib 72f for fitting and holding the bearing member 73d on the left side of the rotary cleaning body 73 is provided. Further, on the right side of the suction port 72b in the housing 72, a rib 72h for fitting and holding the bearing member 73d on the right side of the rotary cleaning body 73 is provided. As a result, the pulley 75a of the pulley / belt mechanism 75 rotates, so that the left core portion 73ac, the left cap body 73ab, the shaft body 73aa, the right cap body 73ab, and the right core portion 73ac rotate. At this time, the left and right bearing members 73d do not rotate.

図５と図７に示すように、回転清掃体７３において、清掃部材７３ｂは、軸体７３ａの蟻溝７３ａｓに取り付けられる清掃ユニット７３ｂａからなり、本実施形態の場合、清掃ユニット７３ｂａは４つ設けられている。
清掃ユニット７３ｂａは、軸体７３ａの蟻溝７３ａｓに取り付けられる細長い基台シート部７３ｂａａと、基台シート部７３ｂａａに設けられた清掃部材本体としてのブラシ毛７３ｂａｂとを有してなる。 As shown in FIGS. 5 and 7, in the rotary cleaning body 73, the cleaning member 73b includes a cleaning unit 73ba attached to the dovetail groove 73as of the shaft body 73a, and in the case of the present embodiment, four cleaning units 73ba are provided. Has been done.
The cleaning unit 73ba includes an elongated base sheet portion 73baa attached to the dovetail groove 73as of the shaft body 73a, and brush bristles 73bab as a cleaning member main body provided in the base sheet portion 73baa.

つまり、本実施形態において、清掃ユニット７３ｂａはブラシユニットであり、回転清掃体７３は回転ブラシである。
また、回転清掃体７３に設けられる４つの清掃ユニット７３ｂａは、それらが同じ種類のものであってもよく、異なる種類のものであってもよい。
例えば、２つの清掃ユニット７３ｂａとしてフローリング清掃用のブラシユニットを用い、他の２つの清掃ユニット７３ｂａとして絨毯清掃用のブラシユニットを用いてもよい。あるいは、２つの清掃ユニット７３ｂａとしてブラシユニットを用い、他の２つの清掃ユニット７３ｂａとしてゴムブレードを用いてもよい。あるいは、全ての清掃ユニット７３ｂａとしてゴムブレードを用いてもよく、この場合、回転清掃体７３は回転ブレードである。 That is, in the present embodiment, the cleaning unit 73ba is a brush unit, and the rotary cleaning body 73 is a rotary brush.
Further, the four cleaning units 73ba provided on the rotary cleaning body 73 may be of the same type or different types.
For example, a brush unit for cleaning flooring may be used as the two cleaning units 73ba, and a brush unit for cleaning carpet may be used as the other two cleaning units 73ba. Alternatively, a brush unit may be used as the two cleaning units 73ba, and a rubber blade may be used as the other two cleaning units 73ba. Alternatively, rubber blades may be used as all the cleaning units 73ba, in which case the rotary cleaning body 73 is a rotary blade.

蟻溝７３ａｓに取り付けられた清掃ユニット７３ｂａにおいて、基台シート部７３ｂａａは蟻溝７３ａｓの奥部に挿入された状態であり、ブラシ毛７３ｂａｂは蟻溝７３ａｓの奥部より幅が狭い開口部７３ａｓａを通って径方向外方へ突出した状態であり、基台シート部７３ｂａａが蟻溝７３ａｓの開口部７３ａｓａに引っ掛かって清掃ユニット７３ｂａが開口部７３ａｓａから取り外せない構造となっている。
また、回転清掃体７３は、図７と図８に示すように、清掃部材７３ｂ（清掃ユニット７３ｂａ）が軸体７３ａの周囲部に対して軸体７３ａの軸心（第３軸心Ｐ３）と交わる方向に脱着可能とされている。なお、ここで「交わる方向」とは、軸体７３ａの軸心（第３軸心Ｐ３）に対して１０°〜９０°程度の角度範囲θの方向を意味する。 In the cleaning unit 73ba attached to the dovetail groove 73as, the base sheet portion 73baa is in a state of being inserted into the inner part of the dovetail groove 73as, and the brush bristles 73bab have an opening 73asa narrower than the inner part of the dovetail groove 73as. The base sheet portion 73ba is caught in the opening 73asa of the dovetail groove 73as, and the cleaning unit 73ba cannot be removed from the opening 73asa.
Further, in the rotary cleaning body 73, as shown in FIGS. 7 and 8, the cleaning member 73b (cleaning unit 73ba) is aligned with the axial center of the shaft body 73a (third axial center P3) with respect to the peripheral portion of the shaft body 73a. It is said that it can be attached and detached in the direction of intersection. Here, the "intersecting direction" means a direction in an angle range θ of about 10 ° to 90 ° with respect to the axial center (third axial center P3) of the shaft body 73a.

本実施形態の場合、軸体７３ａにおいて、各蟻溝７３ａｓの左側端部とキャップ体７３ａｂとの間にそれぞれ隙間部７３ｘが設けられている。
さらに詳しく説明すると、左側のキャップ体７３ａｂは、軸体７３ａの左側端部の端面７３ａｘと対向するフランジ７３ａｂａと、フランジ７３ａｂａの外周部から軸体７３ａの周囲部側へ突出する突出筒７３ａｂｂとを有している。この突出筒７３ａｂｂと各蟻溝７３ａｓの左側端部との間がそれぞれ隙間部７３ｘとなる。
なお、突出筒７３ａｂｂを設けることにより、キャップ体７３ａｂと軸本体７３ａａの端面７３ａｘとの間の隙間に繊維状ダスト（髪の毛、ペットの毛、糸くず等）が入り込んで巻き付くことを抑制している。 In the case of the present embodiment, in the shaft body 73a, a gap portion 73x is provided between the left end portion of each dovetail groove 73as and the cap body 73ab, respectively.
More specifically, the cap body 73ab on the left side includes a flange 73aba facing the end surface 73ax of the left end portion of the shaft body 73a, and a protruding cylinder 73abb protruding from the outer peripheral portion of the flange 73aba toward the peripheral portion side of the shaft body 73a. Have. A gap 73x is formed between the protruding cylinder 73abb and the left end of each dovetail groove 73as.
By providing the protruding cylinder 73ab, it is possible to prevent fibrous dust (hair, pet hair, lint, etc.) from entering and wrapping around in the gap between the cap body 73ab and the end face 73ax of the shaft body 73aa. There is.

このように構成された吸込口体７０によれば、図８に示すように、清掃ユニット７３ｂａの左側端部７３ｂａｘを隙間部７３ｘ側へ引き出し、左側端部７３ｂａｘを軸体７３ａの軸心（第３軸心Ｐ３）と交わる方向に（角度範囲θの方向）に曲げて引き出すことにより、清掃ユニット７３ｂａを蟻溝７３ａｓから取り出すことができる。また、逆の要領で清掃ユニット７３ｂａを蟻溝７３ａｓに挿入することができる。なお、図８では、第３軸心Ｐ３に対して４０°程度の角度で清掃ユニット７３ｂａを蟻溝７３ａｓから引き出している。 According to the suction port body 70 configured in this way, as shown in FIG. 8, the left end portion 73bax of the cleaning unit 73ba is pulled out to the gap portion 73x side, and the left end portion 73bax is the axial center (th) of the shaft body 73a. The cleaning unit 73ba can be taken out from the dovetail groove 73as by bending and pulling out in the direction intersecting the triaxial center P3) (in the direction of the angle range θ). Further, the cleaning unit 73ba can be inserted into the dovetail groove 73as in the reverse manner. In FIG. 8, the cleaning unit 73ba is pulled out from the dovetail groove 73as at an angle of about 40 ° with respect to the third axis P3.

したがって、清掃ユニット７３ｂａが劣化して交換が必要な場合、回転清掃体７３全体を交換するのではなく、劣化した清掃ユニット７３ｂａのみを交換することができるため、メンテナンス費用を抑えることができる。また、洗浄の際も、回転清掃体７３全体を水洗いするのではなく、汚れた清掃ユニット７３ｂａのみを水洗いすることができるため、芯部７３ａｃおよびベアリング７３ａｅ等の金属部品を水洗いすることによる劣化を回避することができる。
また、前記特許文献１および２の吸込口体のようにキャップ部材による軸体の蟻溝からの清掃部材の抜け止めを解除する必要がなく、清掃部材７３ｂが軸体７３ａの周囲部に対して径方向に脱着可能である。そのため、回転清掃体に設けられる清掃部材の数が制限されるという特許文献１の構成が有する課題、および、清掃部材の軸体に対する脱着によって回転清掃体の芯ぶれが生じやすくなるという特許文献２の構成が有する課題を解消することができる。
さらに、蟻溝を有する軸体にキャップ体が固着された従来構造の回転清掃体から大きな設計変更をせずに済むため、回転清掃体７３を低コストにて作製可能である。 Therefore, when the cleaning unit 73ba is deteriorated and needs to be replaced, the maintenance cost can be suppressed because only the deteriorated cleaning unit 73ba can be replaced instead of replacing the entire rotary cleaning body 73. Further, also during cleaning, it is possible to wash only the dirty cleaning unit 73ba instead of washing the entire rotary cleaning body 73 with water, so that deterioration due to washing metal parts such as the core portion 73ac and the bearing 73ae with water can be prevented. It can be avoided.
Further, unlike the suction port bodies of Patent Documents 1 and 2, it is not necessary to release the cleaning member from the dovetail groove of the shaft body by the cap member, and the cleaning member 73b is attached to the peripheral portion of the shaft body 73a. Detachable in the radial direction. Therefore, there is a problem in the configuration of Patent Document 1 that the number of cleaning members provided in the rotary cleaning body is limited, and Patent Document 2 that the centering of the rotary cleaning body is likely to occur due to attachment / detachment of the cleaning member to the shaft body. It is possible to solve the problems of the configuration of.
Further, since it is not necessary to make a major design change from the rotary cleaning body having a conventional structure in which the cap body is fixed to the shaft body having the dovetail groove, the rotary cleaning body 73 can be manufactured at low cost.
