Description

本発明は電気掃除機、特に、その回転ブラシの改良に関する。   The present invention relates to a vacuum cleaner, and more particularly, to an improvement of a rotating brush thereof.

従来の電気掃除機においては、清掃面となる掃除機吸気口及び該掃除機吸気口の中央反対側に吸引流路に連通する吸引口を有する回転ブラシ収容室に、単一の回転ブラシを設ける。つまり、吸引口は回転ブラシ収容室の中央部に位置している。回転ブラシは回転体及び該回転体に螺旋状に配設された清掃片を有する(参照:特許文献1)。   In a conventional vacuum cleaner, a single rotating brush is provided in a rotating brush storage chamber having a cleaner suction port serving as a cleaning surface and a suction port communicating with a suction flow path on the opposite side of the center of the cleaner suction port. . That is, the suction port is located at the center of the rotating brush storage chamber. The rotating brush has a rotating body and a cleaning piece spirally disposed on the rotating body (see Patent Document 1).

しかしながら、上述の従来の電気掃除機においては、回転ブラシの長手方向(たとえば左右方向)の清掃面に対する掃引抵抗は大きく、また、回転ブラシの短手方向(たとえば前後方向)についても、回転ブラシの回転方向および清掃片の配置によりたとえば後方向の清掃面に対する掃引抵抗が大きかった。従って、掃引抵抗が走行方向によって大きくなるので、掃引清掃が容易でないという課題がある。   However, in the above-described conventional vacuum cleaner, the sweep resistance against the cleaning surface in the longitudinal direction (for example, the left-right direction) of the rotating brush is large, and the rotating brush is also moved in the short direction (for example, the front-back direction) of the rotating brush. Depending on the rotation direction and the arrangement of the cleaning pieces, for example, the sweep resistance against the cleaning surface in the rear direction was large. Therefore, there is a problem that sweep cleaning is not easy because the sweep resistance increases depending on the traveling direction.

また、塵埃吸引効率を向上したいという課題もある。   There is also a problem that it is desired to improve dust suction efficiency.

上述の課題を解決するために、本発明に係る電気掃除機は、掃除機吸気口及び吸引流路に連通する吸引口を有し、平行に配置された第1の回転ブラシ及び第2の回転ブラシを収容する回転ブラシ収容室と、第1の回転ブラシ及び第2の回転ブラシを駆動するためのブラシ駆動モータとを具備し、第1の回転ブラシおよび第2の回転ブラシは、前記掃除機吸気口側から見て相互に内回転となるよう回転駆動され、第1の回転ブラシは、第1の回転体及び該第1の回転体の長さ方向にZ巻き螺旋状に配設された複数の毛の集合体よりなるZ巻き清掃片を有し、第2の回転ブラシは、第2の回転体及び該第2の回転体の長さ方向にS巻き螺旋状に配設された複数の毛の集合体よりなるS巻き清掃片を有し、掃除機吸気口側から見て回転ブラシ収容室の前方側を上とし回転ブラシ収容室の後方側を下とした場合、第1の回転ブラシは第2の回転ブラシの左側に配置され、吸引口は第1の回転ブラシと第2の回転ブラシとの間における回転ブラシ収容室の下に配置される。   In order to solve the above-mentioned problem, a vacuum cleaner according to the present invention has a vacuum cleaner suction port and a suction port communicating with a suction channel, and a first rotating brush and a second rotating brush arranged in parallel. A rotating brush accommodating chamber for accommodating a brush, and a brush driving motor for driving a first rotating brush and a second rotating brush, wherein the first rotating brush and the second rotating brush are the cleaner The first rotating brush is rotationally driven so as to rotate inward each other when viewed from the intake port side, and the first rotating brush is disposed in a Z-winding spiral shape in the longitudinal direction of the first rotating body and the first rotating body. A second rotating brush having a Z-winding cleaning piece made of an aggregate of a plurality of bristles, and a second rotating brush and a plurality of S-winding spirals arranged in the longitudinal direction of the second rotating body; A rotating brush storage chamber having an S-winding cleaning piece composed of a set of hairs, viewed from the vacuum cleaner inlet side When the front side is up and the rear side of the rotating brush storage chamber is down, the first rotating brush is disposed on the left side of the second rotating brush, and the suction port is provided with the first rotating brush, the second rotating brush, Between the rotating brush housings.

本発明によれば、第1の回転ブラシ及び第2の回転ブラシの長手方向(たとえば前後方向)の清掃面に対する掃引抵抗は、二本の回転ブラシの長軸方向が掃引の前後方向となり、小さくなる。また、第1の回転ブラシ及び第2の回転ブラシの短手方向(たとえば左右方向)の清掃面に対する掃引抵抗は、2つの回転ブラシが互いに逆方向に回転するように構成されているので、小さくなる。従って、掃引抵抗は前後左右方向で小さくなり、この結果、掃引清掃が容易となる。また、清掃片の巻方向と回転体の回転方向を特定し、吸引口を回転ブラシ収容室の後方側に設けたことにより、清掃片によるゴミ送り方向の終端部に吸引口が位置することになるため、ほとんどの塵埃が吸引口に向い、塵埃吸引効率を著しく向上できる。   According to the present invention, the sweep resistance of the first rotating brush and the second rotating brush with respect to the cleaning surface in the longitudinal direction (for example, the longitudinal direction) is small because the major axis direction of the two rotating brushes is the longitudinal direction of the sweep. Become. In addition, the sweep resistance of the first rotating brush and the second rotating brush with respect to the cleaning surface in the short direction (for example, the left and right direction) is small because the two rotating brushes are configured to rotate in opposite directions. Become. Therefore, the sweep resistance decreases in the front, rear, left and right directions, and as a result, sweep cleaning becomes easy. In addition, the winding direction of the cleaning piece and the rotation direction of the rotating body are specified, and the suction port is provided at the rear side of the rotating brush storage chamber, so that the suction port is located at the end of the dust feeding direction by the cleaning piece. Therefore, most of the dust is directed to the suction port, and the dust suction efficiency can be significantly improved.

For convenience of explanation, the shape and the like are different from those of the embodiment shown in FIG. 1, but the basic configuration is common. (A) is a diagram viewed from slightly above the front of the cleaner inlet (cleaning surface), and (B) is a diagram viewed from the upper right of the front of the cleaner inlet (cleaning surface). In FIG. 2, the upper side is the front side of the cleaner, while the lower side is the rear side of the cleaner, and the suction port 2a for the suction flow path 4 is provided on the lower side.

図2に示すように、回転ブラシ収容室2には、第1の回転ブラシ21及び第2の回転ブラシ22が平行に配置されている。すなわち、掃除機吸気口1c側へ投影したときに、電気掃除機の本体は第1の回転ブラシ21及び第2の回転ブラシ22の長軸方向に平行な長軸を有する把持部を有する。   As shown in FIG. 2, a first rotating brush 21 and a second rotating brush 22 are arranged in parallel in the rotating brush storage chamber 2. That is, when projected to the cleaner inlet 1c side, the main body of the vacuum cleaner has a grip portion having a long axis parallel to the long axis direction of the first rotating brush 21 and the second rotating brush 22.

第1の回転ブラシ21は、第1の回転体211と、第1の回転体211の長さ方向にZ巻き螺旋状に配設された複数のナイロン(登録商標)毛よりなる集合体なるZ巻き清掃片212とによって構成される。尚、「Z巻き」とは図2において手前に見える清掃片212の右上と左下とを結ぶものを言う。他方、第2の回転ブラシ22は、第2の回転体221と、第2の回転体221の長さ方向にS巻き螺旋状に配設された複数のナイロン(登録商標)毛よりなる集合体なるS巻き清掃片222とによって構成される。尚、「S巻き」とは図2において手前に見える清掃片222の左上と右下とを結ぶものを言う。吸引流路4への吸引口2aは第1の回転ブラシ21と第2の回転ブラシ22との間における回転ブラシ収容室2の後方側に配置されている。第1の回転ブラシ21と第2の回転ブラシ22は、相互に内回転となるように駆動する。   The first rotating brush 21 is an aggregate Z composed of a first rotating body 211 and a plurality of nylon (registered trademark) bristles arranged in a Z-winding spiral shape in the longitudinal direction of the first rotating body 211. And a cleaning roll 212. The “Z-winding” refers to a connection between the upper right and the lower left of the cleaning piece 212 seen in the foreground in FIG. On the other hand, the second rotating brush 22 is an aggregate composed of a second rotating body 221 and a plurality of nylon (registered trademark) bristles arranged in an S-wound spiral shape in the length direction of the second rotating body 221. S-shaped cleaning piece 222. The “S-winding” refers to a connection between the upper left and lower right sides of the cleaning piece 222 seen in the foreground in FIG. The suction port 2a to the suction flow path 4 is arranged on the rear side of the rotary brush housing chamber 2 between the first rotary brush 21 and the second rotary brush 22. The first rotating brush 21 and the second rotating brush 22 are driven to rotate inward each other.

清掃片212がZ巻き螺旋状に配設された第1の回転ブラシ21を左、清掃片222がS巻き螺旋状に配設された第2の回転ブラシ22を右としてみた場合において、吸引口2aは、両回転ブラシ21、22間の下側終端部に位置するよう設計されている。   In the case where the first rotating brush 21 in which the cleaning piece 212 is arranged in a spiral spiral shape is viewed as the left, and the second rotating brush 22 in which the cleaning piece 222 is spirally arranged spirally is viewed as the right, a suction port is provided. 2a is designed to be located at the lower end between the rotating brushes 21,22.

図2における回転ブラシ21、22の長さはたとえば55mmであり、また、回転ブラシ21、22間の隙間距離は接触しない程度のたとえば1mmである。さらに、各回転ブラシ21、22の清掃片212、222において、ピッチは等間隔でたとえば10mm、ピッチ数は5以上であり、また、清掃片212、222の回転体211、221の軸に対する傾きは30〜50°たとえば40°である。さらにまた、清掃片212、222の毛の長さはたとえば8mmである。回転ブラシ21、22は、例えば、基布状に2列の清掃片が立設するように取り付けられたテープ状の布をシャフトの外周に巻きつけて構成される。   The length of the rotating brushes 21 and 22 in FIG. 2 is, for example, 55 mm, and the gap distance between the rotating brushes 21 and 22 is, for example, 1 mm that does not make contact. Further, in the cleaning pieces 212 and 222 of the rotating brushes 21 and 22, the pitch is, for example, 10 mm at equal intervals, the pitch number is 5 or more, and the inclination of the cleaning pieces 212 and 222 with respect to the axis of the rotating bodies 211 and 221 is 30 to 50 °, for example, 40 °. Furthermore, the length of the bristles of the cleaning pieces 212 and 222 is, for example, 8 mm. The rotating brushes 21 and 22 are configured, for example, by winding a tape-shaped cloth attached so that two rows of cleaning pieces stand in a base cloth shape around the outer periphery of a shaft.

図3は図1の第1の回転ブラシ21、第2の回転ブラシ22及びブラシ駆動モータ3を示す斜視図、図4は図3の部分拡大斜視図であって、(A)は図3のA矢視斜視図、(B)は図3のB矢視斜視図である。   FIG. 3 is a perspective view showing the first rotary brush 21, the second rotary brush 22, and the brush drive motor 3 of FIG. 1, and FIG. 4 is a partially enlarged perspective view of FIG. FIG. 4B is a perspective view as viewed in the direction of the arrow A, and FIG.

清掃面側から見た各ブラシの配置について、第1の回転ブラシ21を左側、第2の回転ブラシ22を右側として、以下説明する。   The arrangement of the brushes as viewed from the cleaning surface will be described below with the first rotating brush 21 on the left and the second rotating brush 22 on the right.

図3、図4において、左ギア31(図4の(A)のみに図示)及び左ギア31に結合された左プーリ31aと右ギア32及び右ギア32に結合された右プーリ32aとを設け、左ギア31と右ギア32とを対で噛み合わせ、互いに反対方向に回転するようにする。この場合、右ギア32をブラシ駆動モータ3の出力軸に固定する。他方、第1の回転ブラシ21及び第2の回転ブラシ22に、それぞれ、左プーリ21a及び右プーリ22aを固定する。さらに、左プーリ31aと左プーリ21aとの間に左ベルト33を懸けることによって左プーリ31aの左回転を左プーリ21aに伝達し、右プーリ32aと右プーリ22aとの間に右ベルト34を懸けることによって右プーリ32aの右回転を右プーリ22aに伝達する。これにより、ブラシ駆動モータ3は、第1の回転ブラシ21を図3の矢印Lに示すごとく図3の左側方から見て(回転ブラシのギアが取り付けられていない方から見て)左回り(反時計回り)に回転させると同時に、第2の回転ブラシ22を図3の矢印Rに示すごとく図3の左側方から見て右回り(時計回り)に回転させることができる。   3 and 4, a left gear 31 (shown only in FIG. 4A), a left pulley 31a connected to the left gear 31, and a right pulley 32a connected to the right gear 32 and the right gear 32 are provided. The left gear 31 and the right gear 32 mesh with each other in pairs, and rotate in opposite directions. In this case, the right gear 32 is fixed to the output shaft of the brush drive motor 3. On the other hand, a left pulley 21a and a right pulley 22a are fixed to the first rotating brush 21 and the second rotating brush 22, respectively. Further, by suspending the left belt 33 between the left pulley 31a and the left pulley 21a, the left rotation of the left pulley 31a is transmitted to the left pulley 21a, and the right belt 34 is suspended between the right pulley 32a and the right pulley 22a. Thus, the right rotation of the right pulley 32a is transmitted to the right pulley 22a. As a result, the brush drive motor 3 rotates the first rotating brush 21 counterclockwise as viewed from the left side of FIG. 3 (as viewed from the side where the gear of the rotating brush is not attached) as shown by an arrow L in FIG. At the same time as rotating in the counterclockwise direction, the second rotating brush 22 can be rotated clockwise (clockwise) as viewed from the left side in FIG. 3 as shown by the arrow R in FIG.

尚、図3、図4においては、ブラシ駆動モータ3の出力軸が右回りと仮定して左ベルト33は左プーリ31a、21a間に懸け、右ベルト34は右プーリ32a、22a間に懸けているが、ブラシ駆動モータ3の出力軸が左回りであれば、左ベルト33はプーリ32a、21a間に懸け、右ベルト34はプーリ31a、22a間に懸ける。   3 and 4, the left belt 33 is hung between the left pulleys 31a and 21a, and the right belt 34 is hung between the right pulleys 32a and 22a, assuming that the output shaft of the brush drive motor 3 is clockwise. However, if the output shaft of the brush drive motor 3 is counterclockwise, the left belt 33 is hung between the pulleys 32a and 21a, and the right belt 34 is hung between the pulleys 31a and 22a.

図5は図1の回転ブラシ収容室2の第1の回転ブラシ21及び第2の回転ブラシ22の動作を説明するための図である。   FIG. 5 is a view for explaining the operation of the first rotating brush 21 and the second rotating brush 22 of the rotating brush storage chamber 2 of FIG.

図5に示すように、Z巻き清掃片212を備えた第1の回転ブラシ21が先端側(吸引口2aと反対側)から見て左回り(L)に回転することにより、清掃面において、清掃片212に接触した塵埃が、吸引口2a側へ掃き送られる。つまり、清掃片212に接触した塵埃は、第1の回転ブラシ21がL方向の回転に伴って、順次、吸引口2a側の清掃片212が清掃面に露出することにより、吸引口2a側へ掃き送られる。さらに図5において、回転に伴い連続する1本の清掃片212が清掃面に露出する様子を矢印X1として示してある。   As shown in FIG. 5, the first rotating brush 21 provided with the Z-winding cleaning piece 212 rotates counterclockwise (L) when viewed from the tip side (the side opposite to the suction port 2a), so that the cleaning surface has: Dust that has come into contact with the cleaning piece 212 is swept to the suction port 2a side. In other words, the dust that has come into contact with the cleaning piece 212 is moved to the suction port 2a side by the cleaning piece 212 on the suction port 2a side being sequentially exposed to the cleaning surface as the first rotating brush 21 rotates in the L direction. Swept away. Further, in FIG. 5, a state in which one continuous cleaning piece 212 is exposed on the cleaning surface with the rotation is indicated by an arrow X1.

また、S巻き清掃片222を備えた第2の回転ブラシ22が先端側(吸引口2aと反対側)から見て右回り(R)に回転することにより、清掃面において、清掃片222に接触した塵埃が、吸引口2a側へ掃き送られる。つまり、清掃片222に接触した塵埃は、第2の回転ブラシ22がR方向の回転に伴って、順次、吸引口2a側の清掃片222が清掃面に露出することにより、吸引口2a側へ掃き送られる。尚、図5において、回転に伴い連続する1本の清掃片222が清掃面に露出する様子を矢印X2として示してある。   Further, the second rotating brush 22 provided with the S-winding cleaning piece 222 rotates clockwise (R) when viewed from the front end side (the side opposite to the suction port 2a), so that the cleaning brush 222 comes into contact with the cleaning piece 222 on the cleaning surface. The dust is swept to the suction port 2a side. In other words, the dust that has come into contact with the cleaning piece 222 is moved toward the suction port 2a by the cleaning piece 222 on the suction port 2a side being sequentially exposed to the cleaning surface as the second rotating brush 22 rotates in the R direction. Swept away. In FIG. 5, the state where one continuous cleaning piece 222 is exposed on the cleaning surface with the rotation is indicated by an arrow X2.

そして、吸引口2aは、第1の回転ブラシ21と第2の回転ブラシ22の終端側に位置して、清掃片212および清掃片222による塵埃の送りを阻害することなく、吸引口2a側へ送られた塵埃を効率よく吸引することができる。特に、吸引口2aが、第1の回転ブラシ21と第2の回転ブラシ22との間の中腹位置に設けられたものと比較して、清掃片による塵埃の送り機能が阻害されないため、塵埃の吸引効率が高い。   The suction port 2a is located at the end side of the first rotating brush 21 and the second rotating brush 22 and moves toward the suction port 2a without obstructing the feeding of the dust by the cleaning pieces 212 and 222. The sent dust can be efficiently sucked. In particular, since the suction port 2a does not hinder the dust feeding function of the cleaning pieces as compared with the suction port 2a provided at the mid-position between the first rotating brush 21 and the second rotating brush 22, High suction efficiency.

さらに、図5に示すように、第1の回転ブラシ21が左回り(L)しかつ第2の回転ブラシ22が右回り(R)すると、左側の清掃面からの塵埃は、第1の回転ブラシ21のZ巻き清掃片212の内回転により第1の回転ブラシ21と第2の回転ブラシ22との間に位置する吸引流路にも掃き出される。また、右側の清掃面からの塵埃は、第2の回転ブラシ22のS巻き清掃片222の内回転により第1の回転ブラシ21と第2の回転ブラシ22との間に位置する吸引流路にも掃き出される。そして、各回転ブラシによって両回転ブラシ間の吸引流路に掃き集められる塵埃は、矢印Yのように吸引口2aへ向かう。従って、清掃面からのほとんどの塵埃は吸引口2aに効率よく吸引されることになる。   Further, as shown in FIG. 5, when the first rotating brush 21 rotates counterclockwise (L) and the second rotating brush 22 rotates clockwise (R), dust from the cleaning surface on the left side is rotated by the first rotating brush. Due to the inner rotation of the Z-winding cleaning piece 212 of the brush 21, the brush 21 is also swept out to a suction flow path located between the first rotating brush 21 and the second rotating brush 22. Further, dust from the cleaning surface on the right side flows into the suction flow path located between the first rotating brush 21 and the second rotating brush 22 due to the inner rotation of the S winding cleaning piece 222 of the second rotating brush 22. Is also swept away. Then, the dust swept and collected in the suction flow path between the rotating brushes by each rotating brush goes to the suction port 2a as indicated by an arrow Y. Therefore, most of the dust from the cleaning surface is efficiently sucked into the suction port 2a.

第1の回転ブラシ21及び第2の回転ブラシ22の長手方向(たとえば前後方向)の清掃面に対する掃引抵抗は、2本の回転ブラシ21、22の長軸方向が掃引の前後方向となり、回転ブラシ21、22の回転の影響が小さいことより小さい。また、第1の回転ブラシ及び第2の回転ブラシの短手方向(たとえば左右方向)の清掃面に対する掃引抵抗は、2つの回転ブラシが互いに逆方向に回転するので、2つの回転ブラシ21、22が同じ方向に回転する場合と比較して、左右均等かつ小さい。従って、掃引抵抗は前後左右方向で小さくなり、この結果、掃引清掃が容易となる。   The sweep resistance of the first rotating brush 21 and the second rotating brush 22 with respect to the cleaning surface in the longitudinal direction (for example, the longitudinal direction) is such that the major axis direction of the two rotating brushes 21 and 22 is the longitudinal direction of the sweeping. The influence of the rotation of 21 and 22 is small. Further, the sweep resistance of the first rotating brush and the second rotating brush with respect to the cleaning surface in the short direction (for example, the left-right direction) is such that the two rotating brushes rotate in directions opposite to each other. Are equal and smaller in the left-right direction than when they rotate in the same direction. Therefore, the sweep resistance decreases in the front, rear, left and right directions, and as a result, sweep cleaning becomes easy.

尚、本発明は上述の実施の形態の自明の範囲のいかなる変更に適用し得る。例えば、本実施形態では、電気掃除機本体の一部が握り部を構成しているが、別途、握り部を設けた構成としてもよい。その場合においても回転ブラシ長軸と平行に延びる握り部を設けることが好ましい。   It should be noted that the present invention can be applied to any change within the obvious scope of the above-described embodiment. For example, in this embodiment, a part of the main body of the vacuum cleaner constitutes a grip portion, but a configuration in which a grip portion is separately provided may be adopted. Even in such a case, it is preferable to provide a grip portion extending parallel to the long axis of the rotating brush.

本発明は電気掃除機として利用でき、特に小型電気掃除機として、ハンディクリーナ、カークリーナに利用できる。特に、電池を内蔵せずに、たとえばシガーレットライタを介して自動車のバッテリを利用することによりカークリーナを小型化できる。   INDUSTRIAL APPLICABILITY The present invention can be used as a vacuum cleaner, and in particular, can be used as a small vacuum cleaner for a handy cleaner and a car cleaner. In particular, the size of the car cleaner can be reduced by using the battery of the automobile via, for example, a cigarette lighter without incorporating a battery.
