Description

本発明は電気掃除機に係り、特に、操作性の軽減化と集塵性能の向上を図った機能を備えた吸口体に関する。   The present invention relates to a vacuum cleaner, and more particularly, to a mouthpiece having a function of reducing operability and improving dust collection performance.
従来吸口本体は、一般的に上、下ケースと衝撃吸収用のバンパーを結合して構成されている。吸口体内に回転清掃体、床面側には塵埃を遮断する部材や掃除面の上を移動させるためのローラがあり、吸込口開口部は下面側と側面側に形成されているものが多い。
従来の電気掃除の吸口体として、例えば特開平6―93872号公報(特許文献1)及び特開平2002―512号公報(特許文献2)などに記載の各種構成が知られている。
上記公報に記載のものは、下面に吸込口を開口するとともに被清掃面に交差する面に当接することにより開口する吸塵口を有する吸口体を提案している。
A conventional suction body is generally configured by combining an upper and lower case with a shock absorbing bumper. A rotary cleaning body is provided in the suction body, a dust blocking member and a roller for moving the cleaning surface are provided on the floor side, and the suction opening is often formed on the lower surface side and the side surface side.
For example, various configurations described in JP-A-6-93872 (Patent Document 1) and JP-A-2002-512 (Patent Document 2) are known as conventional suction mouthpieces for electric cleaning.
The above-mentioned publication proposes a suction body having a dust suction opening that opens by opening a suction opening on the lower surface and abutting against a surface that intersects the surface to be cleaned.
特開平6―93872号公報Japanese Patent Laid-Open No. 6-93872
特開2002―512号公報Japanese Patent Laid-Open No. 2002-512
上記従来技術では、吸口体の前面側は、吸口体下面部と被清掃面との隙間が形成され、その隙間から塵埃を吸引している。
木床などはその隙間が維持されるので、隙間の大きさに応じて塵埃を吸引することができるが、じゅうたんの場合は、じゅうたんの毛足が隙間を塞いでしまい、開口部が狭くなり、大きな塵埃の吸引ができなくなるという問題がある。
In the above prior art, a gap between the lower surface of the mouthpiece and the surface to be cleaned is formed on the front side of the mouthpiece, and dust is sucked from the gap.
Since the gap is maintained on wooden floors, etc., dust can be sucked according to the size of the gap, but in the case of carpet, the fur of the carpet closes the gap, and the opening becomes narrow, There is a problem that large dust cannot be sucked.
さらに、隙間が狭くなることにより、吸口体内の負圧が高くなり、じゅうたんと密着してしまい、吸口体を前後に移動する際の操作力が大きくなり、操作者の手や腕にかかる負担が増加するという問題がある。
また、前記公報などに記載の従来の吸口体では、家具や壁面に当接した際にだけ吸口体の前方が開口される構造になっているので、開口した場合に大きな塵埃を吸引することができるが、前方が開口していない通常の掃除状態では、前述の吸口体と同様の問題がある。例えば、じゅうたん上にピーナッツなど大きな塵埃が落ちていたとして、従来の吸口体で掃除をすると、じゅうたんと吸口体の隙間が小さいためにピーナッツを吸引することができず、前に押してしまうことになる。その状態のまま、家具や壁に到達して、ようやく吸気口が開口して吸い込むことになる。
In addition, since the gap becomes narrower, the negative pressure in the mouthpiece body becomes higher and the carpet is in close contact with each other, increasing the operating force when moving the mouthpiece back and forth, and placing a burden on the operator's hands and arms. There is a problem of increasing.
In addition, the conventional mouthpiece described in the above publication has a structure in which the front side of the mouthpiece is opened only when it comes into contact with furniture or a wall surface. However, in a normal cleaning state where the front is not open, there is a problem similar to that of the mouthpiece described above. For example, if a large amount of dust such as peanuts has fallen on the carpet, cleaning with the conventional mouthpiece will not suck the peanut because of the small gap between the carpet and the mouthpiece and will push it forward. . In that state, it reaches the furniture and walls, and finally the air inlet opens and sucks.
本発明の目的は、これらの問題を解決し、簡単な構成で、吸口体の前方側の開閉動作を行い、大きな塵埃を効率よく吸い込むことができる電気掃除機を提供することにある。   An object of the present invention is to solve these problems and provide an electric vacuum cleaner that can open and close the suction body with a simple structure and efficiently suck in large dust.
本発明は、吸口体の吸い込み性能を向上するため、吸口本体の床面前方側に刷毛部材を取り付けた基材を設け、前記吸口体の前後進に合わせて回動可能に動き、吸口体前方の開口状態の切り替えを確実に行なったことを特徴とする。   In order to improve the suction performance of the mouthpiece, the present invention provides a base material with a brush member attached to the front side of the floor surface of the mouthpiece body, and moves so that the mouthpiece moves forward and backward. It is characterized in that the switching of the opening state is reliably performed.
本発明によれば、吸口体を前後に移動させることにより、吸口体の床面前方側に刷毛部材を取り付けた基材が回動し、吸口体前進時は前方が開口して吸塵口を広げ、後退時は前方を閉口する。したがって、前進時は、ピーナッツなど大きな塵埃を吸い込むことが容易であり、壁際の塵埃も引き寄せて吸い込むことができる。また、後退時は、刷毛部材が掃除面と当接して、ほぼ垂直状態を保ち吸口前方を閉口するので、吸口体の負圧が大きくなり、じゅうたんなどの奥に溜まった砂ごみなどをしっかり吸い込むことができる。
本発明においては、刷毛部材が被清掃面と接触することで、前方の開閉動作を行うため、摩擦抵抗が低減でき、吸口体を操作する時の手や腕の負担が軽減される。
また、刷毛部材で構成しているため、空気の吸引が刷毛間の隙間からもでき、前進時でも後退時でも大きき塵埃は空気に引きつられ刷毛を押し分けて吸口体内に吸い込まれることになる。これにより、刷毛部材の先端と被清掃面との隙間よりも大きな塵埃を吸い込むことができ、刷毛部材で前方に押したり、挟み込んだりして、被掃除面を傷つけたりすることがない。
一般の掃除機には風量可変用の操作ボタンが付いている。例えば最大である強運転時の場合、本発明によれば、前進時は被清掃面との接触により刷毛部材が後方側へ回動すると同時に吸口体内の負圧により吸引され、前方側が最大に開口されて、より大きな塵埃の吸い込みができる。次に、最小とされる弱運転時の場合、刷毛部材は被清掃面との接触が回避される時点で回動が終わり、前方側の開口は小さくなる。それにより、吸口体内の負圧が確保されるので、十分な吸い込み性能が維持できるという利点がある。
また、吸口体を壁際に沿って長手方向に移動することにより、壁際の塵埃を刷毛部材で掻き取ることができる。
According to the present invention, by moving the suction body back and forth, the base material attached with the brush member on the front side of the floor surface of the suction body rotates, and when the suction body advances, the front opens to widen the dust suction mouth. When closing, close the front. Therefore, when moving forward, it is easy to suck in large dust such as peanuts, and dust near the wall can also be drawn and sucked. Also, when retreating, the brush member comes into contact with the cleaning surface and keeps almost vertical and closes the front of the suction port, increasing the negative pressure of the suction body and sucking in sand and other dust accumulated in the back of the carpet. be able to.
In the present invention, when the brush member comes into contact with the surface to be cleaned, the front opening / closing operation is performed, so that the frictional resistance can be reduced and the burden on the hand and arm when operating the mouthpiece is reduced.
Further, since the brush member is used, air can be sucked from the gaps between the brushes, and large dust is attracted by the air at the time of forward movement and backward movement, and the brush is pushed and sucked into the mouthpiece. Accordingly, dust larger than the gap between the tip of the brush member and the surface to be cleaned can be sucked in, and the surface to be cleaned is not damaged by being pushed forward or pinched by the brush member.
General vacuum cleaners have operation buttons for changing the air flow. For example, in the case of strong driving that is the maximum, according to the present invention, the brush member is rotated backward by contact with the surface to be cleaned during advance, and simultaneously sucked by the negative pressure in the suction mouth, and the front side opens to the maximum. As a result, larger dust can be sucked. Next, in the case of a weak operation that is minimized, the brush member finishes rotating when contact with the surface to be cleaned is avoided, and the opening on the front side becomes smaller. Thereby, since the negative pressure in the mouthpiece is ensured, there is an advantage that sufficient suction performance can be maintained.
Moreover, the dust at the wall can be scraped off by the brush member by moving the suction body in the longitudinal direction along the wall.
吸口体の前方部分の開閉機構を、少ない部品点数で、吸口体としての大きさや重量を損なわずに実現した。   The opening and closing mechanism of the front part of the mouthpiece is realized with a small number of parts without losing the size and weight of the mouthpiece.

The mouthpiece lower case 101 and the upper case 102 are connected via a bumper 301 for shock absorption. An upper portion of the electric motor holding member 405 forms an air passage between the suction body upper case 401 and constitutes an air passage chamber 404 that communicates the rotary cleaning body chamber 403 and the first connection pipe 102.
吸口体下ケース101の床面前方側101aに被清掃面に当接して吸口体前方部分を覆う回動枠体121が設置され、該回動枠体121の下面側には刷毛部材で形成した基材122が取り付けられている。以下回動枠体と刷毛部材で形成した基材を合わせて一体となった状態を回動体130と称する。回動体130は前記吸口体206の前後の往復動作に合わせて前後に回動可能に取り付けられている。   A rotating frame body 121 that is in contact with the surface to be cleaned and covers a front portion of the suction body is installed on the floor surface front side 101a of the lower suction body case 101, and a brush member is formed on the lower surface side of the rotating frame body 121. A substrate 122 is attached. Hereinafter, a state in which the rotating frame body and the base material formed of the brush member are combined together is referred to as a rotating body 130. The rotating body 130 is attached so as to be able to rotate back and forth in accordance with the reciprocating motion of the suction body 206 before and after.
回動体130は、吸口体101aの逆U字形状部内に設置されており、回動体130の前後方向の回動動作範囲を逆U字形状部分の壁面101aと101bで規制している。   The rotating body 130 is installed in the inverted U-shaped portion of the suction body 101a, and the rotating operation range in the front-rear direction of the rotating body 130 is restricted by the wall surfaces 101a and 101b of the inverted U-shaped portions.
図5に本実施例による回動体130の形状を示す。(a)に示すように、121a、121bは回動枠体121が回動可能なように丸棒形状の支持軸であり、121cは刷毛部材で形成した基材122を取り付ける部材であり、全て同一部材で形成されている。取り付け部材121cには前記基材を挿入できるように溝121dを設けている。(b)は回動枠体121に刷毛部材で形成した基材122が取り付けられて一体となり、回動体130となった状態を示す。   FIG. 5 shows the shape of the rotating body 130 according to this embodiment. As shown to (a), 121a, 121b is a support rod of a round bar shape so that the rotation frame 121 can be rotated, 121c is a member for attaching the base material 122 formed of a brush member, It is formed of the same member. The mounting member 121c is provided with a groove 121d so that the base material can be inserted. (B) shows a state in which a rotating body 130 is formed by attaching a base material 122 formed of a brush member to the rotating frame body 121.
支持軸121aと121bの長さL1とL2は異なり、回動体130を吸口体下ケース101aに挿入する時に左右の組立て間違いが発生しないように片側を長く設定している。回動体130の下面方向の長さは、その先端が床面に当接する長さに設定している。なお、回動枠体121はガラス繊維を含有した長繊維強化熱可塑性樹脂(ダイセル化学工業社)を用いている。
図6、図7に本実施例による下ケース101の前方部の拡大図と断面図を示す。回動体130の取り付けは、まず、下ケース101aの挿入口303に回動枠体121の支持軸121aを挿入し、反対側の支持軸121bを挿入口304に入れる。挿入口304には図7に示すように爪部304aが形成されているので、その爪部304aを乗り越えるように支持軸121bを嵌め込み、回動枠体121が爪部304aから抜けない構造としている。
以上の構成により、吸口体の長手方向や前方や斜め方向からの衝撃には、下ケース101aの逆U字形状部側壁面と回動枠体の側壁面が一体となることで緩和される。したがって、吸口体の強度が保たれ、撓んでも回動体130が外れる心配がない。
The lengths L1 and L2 of the support shafts 121a and 121b are different, and one side is set to be long so that a left and right assembly error does not occur when the rotating body 130 is inserted into the lower suction body case 101a. The length of the rotating body 130 in the lower surface direction is set to a length such that the tip thereof is in contact with the floor surface. In addition, the rotation frame 121 uses the long fiber reinforced thermoplastic resin (Daicel Chemical Industries Ltd.) containing glass fiber.
6 and 7 are an enlarged view and a sectional view of the front portion of the lower case 101 according to this embodiment. To attach the rotating body 130, first, the support shaft 121a of the rotating frame 121 is inserted into the insertion port 303 of the lower case 101a, and the opposite support shaft 121b is inserted into the insertion port 304. As shown in FIG. 7, a claw portion 304a is formed in the insertion port 304. Therefore, the support shaft 121b is fitted so as to get over the claw portion 304a so that the rotating frame 121 does not come out of the claw portion 304a. .
With the above configuration, the impact from the longitudinal direction, the front side, or the diagonal direction of the mouthpiece is alleviated by integrating the side wall surface of the inverted U-shaped portion of the lower case 101a and the side wall surface of the rotating frame. Therefore, the strength of the mouthpiece is maintained, and there is no fear that the rotating body 130 will come off even if it is bent.
次に本実施例の動作を説明する。図4において、掃除時に吸口体206を前進させると、回動体130は先端の刷毛部材122が被清掃面と当接しているため、摩擦により回動体130が後方へ回動し、吸口体前方が開口する。同時に吸口体内の負圧により回動体130がさらに吸引されて開口部が広がるので、ピーナツなど大きな塵埃を吸い込むことが容易になる。さらに、壁際を掃除する場合は隅部の塵埃も引き寄せて吸い込むことができる。   Next, the operation of this embodiment will be described. In FIG. 4, when the suction body 206 is advanced during cleaning, the rotating body 130 has the brush member 122 at the tip thereof in contact with the surface to be cleaned. Open. At the same time, the rotating body 130 is further sucked by the negative pressure in the mouthpiece and the opening is widened, so that it becomes easy to suck in large dust such as peanuts. Further, when cleaning the wall, dust at the corners can also be drawn and sucked.
このとき、回動体130の先端は被清掃面とわずかに接している程度なので、吸口体206の床面側と被清掃面の摩擦抵抗が減少し、前進時の操作がスムーズに行なえる。すなわち、操作するときの手や腕の負担が軽減され、まるで、吸口体206が自走するような感覚が得られる。
次に、吸口体206を後進させると、回動体130は掃除機本体の吸引力に対抗して、回動体130の先端が被清掃面との摩擦により前方側に回動し、前方を閉口する。刷毛部材は被清掃面と当接して、ほぼ垂直状態を保ち吸口前方を閉口するので、吸口体の負圧が大きくなり、じゅうたんなどの奥に溜まった砂ごみなどをしっかり吸い込むことができる。
本実施例においては、被清掃面との接触を刷毛部材で構成しているので、空気を刷毛間の隙間からも吸引することができ、前進時でも後退時でも大きき塵埃は空気に引きつられ刷毛を押し分けて吸口体内に吸い込むことができる。
一方、一般の掃除機には風量可変用の操作ボタンが付いている。例えば最大である強運転時の場合、本発明によれば、前進時は被清掃面との接触により刷毛部材が後方側へ回動すると同時に吸口体内の負圧により吸引され、前方側が最大に開口されて、より大きな塵埃の吸い込みができる。次に、最小とされる弱運転時の場合、刷毛部材は被清掃面との接触が回避される時点で回動が終わり、前方側の開口は小さくなる。しかしながら、吸口体内の負圧が確保されることになるので、十分な吸い込み性能が維持できるという利点がある。
以上のことから、掃除機本体の吸引力の大きさに合わせて、回動体130の構成を変更することができ、機種展開などが容易になる。
さらに、回動体130は回転清掃体104よりも前方側に位置しているので、吸口体206を壁際に沿って長手方向に移動することにより、壁際の塵埃を回動体130の刷毛部材で掻き取ることができる。
At this time, since the tip of the rotating body 130 is slightly in contact with the surface to be cleaned, the frictional resistance between the floor surface side of the suction body 206 and the surface to be cleaned is reduced, and the operation at the time of forward movement can be performed smoothly. That is, the burden on the hands and arms when operating is reduced, and a feeling that the mouthpiece 206 is self-propelled can be obtained.
Next, when the suction body 206 is moved backward, the rotating body 130 opposes the suction force of the cleaner body, the front end of the rotating body 130 is rotated forward by friction with the surface to be cleaned, and the front is closed. . The brush member is in contact with the surface to be cleaned and closes the front of the suction port while maintaining a substantially vertical state, so that the negative pressure of the suction body increases and sand dust collected in the back of the carpet or the like can be sucked firmly.
In this embodiment, since the contact with the surface to be cleaned is constituted by the brush member, air can be sucked also from the gap between the brushes, and large dust is attracted by the air at the time of forward movement and backward movement. The brush can be pushed and sucked into the mouthpiece.
On the other hand, general vacuum cleaners have operation buttons for changing the air volume. For example, in the case of strong driving that is the maximum, according to the present invention, the brush member is rotated backward by contact with the surface to be cleaned during advance, and simultaneously sucked by the negative pressure in the suction mouth, and the front side opens to the maximum. As a result, larger dust can be sucked. Next, in the case of a weak operation that is minimized, the brush member finishes rotating when contact with the surface to be cleaned is avoided, and the opening on the front side becomes smaller. However, since the negative pressure in the mouthpiece is ensured, there is an advantage that sufficient suction performance can be maintained.
From the above, the structure of the rotating body 130 can be changed according to the magnitude of the suction force of the cleaner body, and the model development and the like are facilitated.
Further, since the rotating body 130 is located in front of the rotary cleaning body 104, the dust at the wall is scraped off by the brush member of the rotating body 130 by moving the suction body 206 in the longitudinal direction along the wall. be able to.
本実施例においては、回動体130の刷毛部材122を1種類で構成しているが、図8に示すように長手方向に2種類以上の刷毛部材を用いても同様の効果が得られる。本実施例では、中央部801に刷毛剛性が小さく、長さが被清掃面に当接しない短いものを取り付け、両端部802には刷毛剛性が高く、長さが被清掃面に当接するものを取り付けて構成している。吸口体206の前後進に合わせて前方を開閉する動作の役目(被清掃面との接触部分)を両端の刷毛材802に持たせ、中央部の刷毛801は吸口体内の負圧により吸引力で開口するように設定しているので、開口部を常時大きく維持できるため、粗大固形の塵埃を吸い込ませることができる。 In the present embodiment, the brush member 122 of the rotating body 130 is composed of one kind, but the same effect can be obtained even if two or more kinds of brush members are used in the longitudinal direction as shown in FIG. In this embodiment, a short brush with low brush rigidity and a length that does not contact the surface to be cleaned is attached to the central portion 801, and both ends 802 have high brush rigidity and a length that contacts the surface to be cleaned. Installed and configured. The brush material 802 at both ends has a role of opening / closing the mouthpiece 206 in accordance with the forward / backward movement of the mouthpiece 206 (contact portion with the surface to be cleaned). Since the opening is set so that the opening can always be kept large, coarse solid dust can be sucked in.
また、図8と同様の構成において、両端の刷毛材802を導電性繊維のものにすることにより、マイナスイオンを発生する機能を付加することができる。
図9に吸口体の側面断面を示す。本実施例では、回転清掃体104の回転により、清掃部材104aが下ケース101と摺擦し、静電気を発生させ、清掃部材104aが正極に、下ケース101が負極に帯電する。発生した負電荷は、上ケース401や下ケース101を通って、導電性繊維802に到達する。そして、この導電性繊維802の負電荷と正極に帯電した回転清掃体104の清掃部材104aとの間でコロナ放電が発生する。
Further, in the same configuration as in FIG. 8, the function of generating negative ions can be added by making the brush material 802 at both ends of conductive fibers.
FIG. 9 shows a side sectional view of the mouthpiece. In the present embodiment, the rotation of the rotary cleaning body 104 causes the cleaning member 104a to rub against the lower case 101 to generate static electricity, and the cleaning member 104a is charged to the positive electrode and the lower case 101 is charged to the negative electrode. The generated negative charges reach the conductive fiber 802 through the upper case 401 and the lower case 101. Corona discharge is generated between the negative charge of the conductive fiber 802 and the cleaning member 104a of the rotary cleaning body 104 charged to the positive electrode.
このコロナ放電により放電した負電荷は、空気中の酸素を電離してイオン化し、マイナスイオンを発生させる。   The negative charge discharged by this corona discharge ionizes oxygen in the air and ionizes it, generating negative ions.
一般に被清掃面上の塵埃は正極に帯電している場合が多いことが知られているが、吸口体を前後に移動させて清掃を行うときに、この発生したマイナスイオンが回転清掃体室の床下開口部より放出し、被清掃面上の塵埃を電気的に中和し、これにより、被清掃面からの塵埃の剥離が容易になる。   In general, it is known that the dust on the surface to be cleaned is often charged on the positive electrode, but when the suction body is moved back and forth for cleaning, the generated negative ions are generated in the rotary cleaning body chamber. The dust discharged from the underfloor opening is electrically neutralized with the dust on the surface to be cleaned, which facilitates the separation of the dust from the surface to be cleaned.
以上のことから、刷毛部材802を導電性繊維にすることで、吸口体前方の開閉機能とマイナスイオン発生機能の両者を兼ね備えた吸口を提供することができる。   From the above, by using the brush member 802 as a conductive fiber, it is possible to provide a suction port having both an opening / closing function in front of the suction body and a negative ion generation function.
本実施例では、図10に示すように、回動体130を被清掃面に対して上下方向に移動可能なように、吸口体101aの挿入口303、304に長穴305を設けている。これにより、被清掃面が毛足の長いシャギーじゅうたんの場合でも、回動体130が長穴305の上部に移動して回動することになるので、じゅうたんの毛と回動体130の刷毛材との摩擦抵抗が大きくなる心配がない。さらに、開口を塞ぐこともなく、塵埃の侵入が確保できる。
毛足の短いじゅうたんの場合は、回動体130が長穴305の下部に移動して回動するころになるので、実施例1と同様の動作が得られる。
したがって、毛足の長いじゅうたんでも短いじゅうたんでも長さに応じて回動体130が上下するので、操作者の手や腕の労力が軽減され、吸い込み性能も維持することができる。
In this embodiment, as shown in FIG. 10, elongated holes 305 are provided in the insertion ports 303 and 304 of the suction body 101a so that the rotating body 130 can be moved in the vertical direction with respect to the surface to be cleaned. As a result, even when the surface to be cleaned is a shaggy carpet having a long bristle, the rotating body 130 moves to the upper part of the elongated hole 305 and rotates, so that the hair of the carpet and the brush material of the rotating body 130 There is no worry of increased frictional resistance. Furthermore, the intrusion of dust can be ensured without closing the opening.
In the case of a carpet with short hairs, the rotating body 130 moves to the lower part of the elongated hole 305 and turns so that the same operation as in the first embodiment can be obtained.
Therefore, since the rotating body 130 moves up and down according to the length of the long and short carpets, the labor of the operator's hands and arms is reduced, and the suction performance can be maintained.
なお、本実施例は床移動型の掃除機だけでなく、アップライト式やスティック式の掃除機にも適用できる。   Note that this embodiment can be applied not only to a floor moving type vacuum cleaner but also to an upright type or stick type vacuum cleaner.
