Description

本発明は、前側に吸込口と連通する前側吸込口を備え、前後動可能な電気掃除機およびその吸込口体に関する。   The present invention relates to a vacuum cleaner that includes a front suction port that communicates with a suction port on the front side and that can move back and forth, and a suction port body thereof.

従来、この種の電気掃除機は、電動送風機を収容した掃除機本体を備えている。この掃除機本体には、電動送風機の吸込側に連通して、ホース体、延長管および吸込口体としての床ブラシが順次接続される。この床ブラシにおいては、壁際などの前側の塵埃を吸い込むために、下面に開口した吸込口に連通して前側に前側吸込口が開口されているものがある。このような前側吸込口を備えた床ブラシにおいては、この前側吸込口に、床ブラシの前後動に対応して回動する回転体が設けられており、この回転体には、外周に溝部が形成され、床ブラシの前進時に溝部が被掃除面としての床面に対向して吸込口と連通し、床ブラシの後退時に回転体が回動して溝部が吸込口側に移動し、吸込口の真空度を向上する（例えば、特許文献１参照。）。
特開２００４−４９７７６号公報（第５頁、図５−６） Conventionally, this type of vacuum cleaner includes a vacuum cleaner body that houses an electric blower. A hose body, an extension pipe, and a floor brush as a suction port body are sequentially connected to the vacuum cleaner main body in communication with the suction side of the electric blower. In some floor brushes, in order to suck in dust on the front side such as near a wall, a front suction port is opened on the front side in communication with a suction port opened on the lower surface. In the floor brush provided with such a front suction port, a rotating body that rotates in response to the back and forth movement of the floor brush is provided at the front suction port, and the rotating body has a groove on the outer periphery. When the floor brush moves forward, the groove portion faces the floor surface as the surface to be cleaned and communicates with the suction port. (See, for example, Patent Document 1).
Japanese Patent Laying-Open No. 2004-49776 (5th page, FIG. 5-6)

しかしながら、上述の電気掃除機では、吸込口での真空度の調整はできるものの、前側吸込口から塵埃を吸い込むスペースを確保しにくく、また、回転体が床ブラシの前端に位置しているため、回転ブラシを床ブラシの前端に位置させることができないので、壁際の塵埃を吸い込みにくいという問題点を有している。   However, in the above vacuum cleaner, although the degree of vacuum at the suction port can be adjusted, it is difficult to secure a space for sucking dust from the front suction port, and the rotating body is located at the front end of the floor brush, Since the rotating brush cannot be positioned at the front end of the floor brush, there is a problem that it is difficult to suck in dust at the wall.

このため、床ブラシの掃除性能の一層の向上が望まれている。   For this reason, the further improvement of the cleaning performance of a floor brush is desired.

本発明は、このような点に鑑みなされたもので、掃除性能を向上した電気掃除機およびその吸込口体を提供することを目的とする。   This invention is made | formed in view of such a point, and it aims at providing the vacuum cleaner which improved the cleaning performance, and its suction inlet.

A front lid that is continuous between both sides , and a roller-like shape that is located behind the suction port and that has an outer periphery that contacts the surface to be cleaned, and that causes friction with the surface to be cleaned to respond to the longitudinal movement of the case body. With a rotating back and forth motion detecting means, the opening and closing motion of the back and forth motion detecting means increases the opening amount of the front suction port when the case body moves forward, and decreases the opening amount of the front suction port when the case body moves backward. And an opening / closing mechanism for moving the front lid body.

本発明によれば、ケース体を前側に移動させた際には、ローラ状の前後動検出手段が、その外周と被掃除面との摩擦により前方に回動することで前側蓋体が前側吸込口の下部の開口量を増加させて前側吸込口から比較的大きい塵埃を前方へと押しやることなく吸込口へと吸い込むことができ、ケース体を後側に移動させた際には、ローラ状の前後動検出手段が、その外周と被掃除面との摩擦により後方に回動することで前側蓋体が前側吸込口の開口量を減少させて吸込口の真空度が向上し、細塵などの塵埃を効率よく吸い込むことができるなど、異なる大きさの塵埃の吸い込みに効率よく対応でき、掃除性能が向上する。 According to the present invention, when the case body is moved to the front side, the roller-like back-and-forth movement detecting means is rotated forward by the friction between the outer periphery and the surface to be cleaned, so that the front lid body is sucked into the front side. increasing the amount of opening of the lower mouth of relatively large dust can be sucked into the suction port without pushing forward from the front suction port and, when moving the case body to the rear, the roller-shaped is back-and-forth movement detecting means, the front lid by rotating rearwardly to reduce the amount of opening of the front suction inlet improves the degree of vacuum in the suction opening by the friction between its outer periphery and the surface to be cleaned, such as fine dust It is possible to efficiently suck in dust of different sizes , such as being able to suck in dust efficiently , and the cleaning performance is improved.

このとき、床ブラシ13のケース体21を前進、すなわち前進方向D1へと移動させると、図２および図３(a)に示すように、床面Ｆと揺動体58の起毛布部61bとの摩擦により、揺動体本体61が床ブラシ13に対して相対的に前方へと回動することで、カム部62の前端側が下方へと移動し、このカム部62により支持された前カバー49の突出部54の係合部57の後端側が下がることで、前カバー49が後方へと回動して、前側吸込口48の開口量を増加させ、床ブラシ13の前側の床面Ｆ上に位置する塵埃を、前側吸込口48から吸い込む。 At this time, if the case body 21 of the floor brush 13 moves forward, that is, moves in the forward direction D1, the floor surface F and the raised cloth portion 61b of the rocking body 58 are moved as shown in FIG. 2 and FIG. Due to the friction, the oscillating body 61 is rotated forward relative to the floor brush 13 so that the front end side of the cam portion 62 moves downward, and the front cover 49 supported by the cam portion 62 When the rear end side of the engaging portion 57 of the projecting portion 54 is lowered, the front cover 49 is rotated rearward to increase the opening amount of the front suction port 48, and on the floor surface F on the front side of the floor brush 13. The located dust is sucked from the front suction port 48.

また、床ブラシ13のケース体21を後退、すなわち後退方向D2へと移動させると、図１および図３(b)に示すように、床面Ｆと揺動体58の起毛布部61bとの摩擦により、揺動体本体61が床ブラシ13に対して相対的に後方へと回動することで、カム部62の前端側が上方へと移動し、このカム部62により支持された前カバー49の突出部54の係合部57の後端側が上がることで、前カバー49が前方へと回動して、前側吸込口48の開口量を減少させ、吸込口31の真空度を増加させる。 Further, when the case body 21 of the floor brush 13 is retracted, that is, moved in the retracting direction D2, as shown in FIGS. 1 and 3 (b), the friction between the floor surface F and the raised cloth portion 61b of the rocking body 58 is caused. As a result, the rocking body main body 61 is rotated rearward relative to the floor brush 13 so that the front end side of the cam portion 62 moves upward, and the front cover 49 supported by the cam portion 62 protrudes. When the rear end side of the engaging portion 57 of the portion 54 is raised, the front cover 49 is rotated forward, the opening amount of the front suction port 48 is decreased, and the vacuum degree of the suction port 31 is increased.

さらに、図３(c)に示すように、床ブラシ13を前進させて前カバー49を壁部Ｗへと押し付けた場合には、前カバー49の回動部52が被取付部51に対して相対的に後方へと回動し、回転ブラシ32の清掃部材42が前カバー49の下部から前側吸込口48の前方へと相対的に突出し、壁部Ｗの近傍、すなわち壁ぎわの床面Ｆ上の塵埃を吸込口31から吸い込む。   Further, as shown in FIG. 3 (c), when the floor brush 13 is advanced and the front cover 49 is pressed against the wall portion W, the rotating portion 52 of the front cover 49 moves against the attached portion 51. The cleaning member 42 of the rotating brush 32 protrudes relatively forward from the lower part of the front cover 49 to the front of the front suction port 48, and in the vicinity of the wall W, that is, on the floor F of the wall. Inhale the dust from the inlet 31.

この塵埃とともに吸い込まれた空気は、吸込風となり、床ブラシ13、延長管12、ホース体８および本体吸込口７を経由して集塵収容室に流入し、集塵カップ３内に吸い込まれ、粗塵と細塵とが分離されて電動送風機２に吸い込まれ、電動送風機２を通過して排気風となり、図示しない排気口から掃除機本体１の外部へと排気される。   The air sucked together with the dust becomes a suction wind, flows into the dust collecting chamber through the floor brush 13, the extension pipe 12, the hose body 8 and the main body suction port 7, and is sucked into the dust collecting cup 3. Coarse dust and fine dust are separated and sucked into the electric blower 2, passes through the electric blower 2 to become exhaust air, and is exhausted from the exhaust port (not shown) to the outside of the cleaner body 1.

上述したように、上記一実施の形態によれば、ケース体21の前後動に対応して回動する揺動体58により前カバー49を摺動させて前側吸込口48の開口量を増減させることにより、ケース体21を前側に移動させた際には、前側吸込口48の開口量が増加して前側吸込口48から塵埃を吸込口31へと吸い込むことができ、ケース体21を後側に移動させた際には、前側吸込口48の開口量が減少して吸込口31の真空度が向上し、塵埃を効率よく吸い込むことができる。   As described above, according to the embodiment, the front cover 49 is slid by the swinging body 58 that rotates in response to the back-and-forth movement of the case body 21, and the opening amount of the front suction port 48 is increased or decreased. Thus, when the case body 21 is moved to the front side, the opening amount of the front suction port 48 is increased so that dust can be sucked into the suction port 31 from the front suction port 48, and the case body 21 is moved to the rear side. When moved, the opening amount of the front suction port 48 is reduced, the degree of vacuum of the suction port 31 is improved, and dust can be sucked efficiently.

すなわち、例えば細かい砂ごみなどの細塵、あるいは微細塵の吸い込みを向上するためには、吸込口31の真空度を向上することが重要であるものの、吸込口31の真空度を向上するために前側吸込口48の開口量を単に減少させると、例えば米粒などの比較的大きい塵埃の吸い込みが良好でなく、また、前側吸込口48の開口量を単に増加させると、細塵、あるいは微細塵などの吸い込みが低下する。このため、上記一実施の形態では、床ブラシ13を前進させた場合に、床ブラシ13の前側の床面Ｆ上の比較的大きい塵埃を前カバー49が前方へと押しやることがないように、前側吸込口48の開口量を増加させて、比較的大きい塵埃でも前側吸込口48から吸い込むことができるようにし、床ブラシ13を後退させた場合には、前側吸込口48の開口量を減少させて吸込口31の真空度を向上し、床面Ｆ上の細塵、あるいは微細塵などを、確実に吸い込むことができるようにしたため、異なる大きさの塵埃の吸い込みに効率よく対応でき、掃除性能が向上する。   That is, in order to improve the suction of fine dust such as fine sand dust, or to improve the suction of fine dust, it is important to improve the vacuum of the suction port 31, but to improve the vacuum of the suction port 31. If the opening amount of the front suction port 48 is simply reduced, suction of relatively large dust such as rice grains is not good, and if the opening amount of the front suction port 48 is simply increased, fine dust or fine dust etc. Inhalation of is reduced. Therefore, in the above-described embodiment, when the floor brush 13 is moved forward, the front cover 49 does not push forward the relatively large dust on the floor surface F on the front side of the floor brush 13. Increase the opening amount of the front suction port 48 so that relatively large dust can be sucked from the front suction port 48, and when the floor brush 13 is retracted, the opening amount of the front suction port 48 is decreased. The suction level of the suction port 31 is improved and fine dust or fine dust on the floor surface F can be reliably sucked in. Therefore, it can efficiently handle the suction of dust of different sizes, and cleaning performance Will improve.

また、開閉機構として、床面Ｆと接触してこの床面Ｆとの間の摩擦により回動する揺動体58を設け、この揺動体58のカム部62により、前カバー49の突出部54の係合部57を支持することで、ケース体21の前後動に対応して回動した揺動体58により前カバー49が前側吸込口48の開口量を増減させる構成を、容易に構成できる。   Further, as the opening / closing mechanism, there is provided a rocking body 58 that comes into contact with the floor surface F and rotates by friction with the floor surface F, and the cam portion 62 of the rocking body 58 causes the protrusion 54 of the front cover 49 to move. By supporting the engaging portion 57, it is possible to easily configure the configuration in which the front cover 49 increases or decreases the opening amount of the front suction port 48 by the swinging body 58 that rotates in response to the back and forth movement of the case body 21.

さらに、吸込口31および前側吸込口48に臨んで回転ブラシ32を回転可能に設け、前カバー49を、ケース体21に軸支された被取付部51と、壁部Ｗなどに衝突した際に被取付部51に対して回動する回動部52とで構成するので、床ブラシ13を壁部Ｗなどに押し付けると、回動部52が被取付部51に対して回動し、回転ブラシ32が壁部Ｗに近づくので、壁部Ｗの近傍の床面Ｆ上の塵埃を、効率よく吸い込むことができる。   Further, the rotary brush 32 is rotatably provided facing the suction port 31 and the front suction port 48, and when the front cover 49 collides with the mounted portion 51 pivotally supported by the case body 21 and the wall portion W or the like. Since the rotating portion 52 is configured to rotate with respect to the attached portion 51, when the floor brush 13 is pressed against the wall portion W or the like, the rotating portion 52 rotates with respect to the attached portion 51, and the rotating brush. Since 32 approaches the wall portion W, dust on the floor surface F in the vicinity of the wall portion W can be efficiently sucked.

また、床ブラシ13を壁部Ｗなどに押し付けた際に被取付部51に対して回動した回動部52は、後面が回転ブラシ32の清掃部材42の先端に当接する程度まで回動するので、前カバー49の下方から清掃部材42の先端が床ブラシ13の前方に突出するので、壁部Ｗの真下付近の床面Ｆ上の塵埃をも掻き取ることが可能になる。   Further, the rotating portion 52 that rotates with respect to the attached portion 51 when the floor brush 13 is pressed against the wall portion W or the like rotates to such an extent that the rear surface comes into contact with the tip of the cleaning member 42 of the rotating brush 32. Therefore, since the tip of the cleaning member 42 protrudes from the lower side of the front cover 49 to the front of the floor brush 13, dust on the floor surface F near the wall W can be scraped off.

しかも、前側吸込口48の上部に取り付けられた前カバー49の摺動により前側吸込口48の開口量を増減させる構成としたので、回転ブラシ32を前側吸込口48の最前部に位置させることができ、床ブラシ13の前側での集塵効率を、より向上できる。   Moreover, since the opening amount of the front suction port 48 is increased or decreased by sliding the front cover 49 attached to the upper part of the front suction port 48, the rotating brush 32 can be positioned at the foremost part of the front suction port 48. The dust collection efficiency on the front side of the floor brush 13 can be further improved.

そして、このような床ブラシ13を備えることで、電気掃除機の掃除性能をも向上できる。   And by providing such a floor brush 13, the cleaning performance of a vacuum cleaner can also be improved.

なお、上記一実施の形態において、揺動体58は回転ブラシ32の両側に取り付けることもできる。この場合には、揺動体58を回動させる床面Ｆとの間の摩擦力を、より確実に得ることができ、また、前カバー49を左右両側で摺動させるので、前カバー49の動作がより確実になる。   In the above embodiment, the oscillating body 58 can be attached to both sides of the rotating brush 32. In this case, the frictional force with the floor surface F that rotates the rocking body 58 can be obtained more reliably, and the front cover 49 is slid on both the left and right sides. Is more certain.

また、上記一実施の形態では、前カバー49を摺動させることで前側吸込口48の開口量を増減させるが、ケース体21の前後動に対応して前側吸込口48の開口量を増減させる構成であれば、前カバー49は、例えば回動など、摺動以外の動作をするものでもよい。 Further, in the embodiment above Symbol exemplary, but increases or decreases the amount of opening of the front suction port 48 by causing front slide cover 49, or decrease the amount of opening of the front suction port 48 corresponding to the forward and backward movements of the case body 21 If it is the structure to be made, the front cover 49 may perform operations other than sliding such as turning.

そして、電気掃除機としては、キャニスタ型に限らず、例えば自走式の電気掃除機などでもよく、また、例えば床ブラシ13が掃除機本体１の下面に直接形成されたアップライト型、あるいはハンディ型などであっても対応させて用いることができ、さらに、紙パック式の電気掃除機などにも適用できる。   The electric vacuum cleaner is not limited to the canister type, and may be, for example, a self-propelled electric vacuum cleaner, or an upright type in which the floor brush 13 is directly formed on the lower surface of the vacuum cleaner body 1 or a handy type. Even a mold or the like can be used correspondingly, and can also be applied to a paper pack type vacuum cleaner or the like.
