実施の形態１．
図１は、実施の形態１による電気掃除機１を示す斜視図である。図１に示すように、電気掃除機１は、吸込具２、吸引パイプ３、吸引ホース４、掃除機本体５、ハンドル６、及び操作部７を備える。 Embodiment 1 FIG.
FIG. 1 is a perspective view showing a vacuum cleaner 1 according to the first embodiment. As shown in FIG. 1, the vacuum cleaner 1 includes a suction tool 2, a suction pipe 3, a suction hose 4, a cleaner body 5, a handle 6, and an operation unit 7.

吸込具２は、吸引パイプ３の一端部に対して、着脱可能に接続される。吸引パイプ３の他端部は、吸引ホース４の一端部に対して、着脱可能に接続される。吸引ホース４の他端部は、掃除機本体５のホース接続口に対して、着脱可能に接続される。   The suction tool 2 is detachably connected to one end of the suction pipe 3. The other end of the suction pipe 3 is detachably connected to one end of the suction hose 4. The other end of the suction hose 4 is detachably connected to the hose connection port of the cleaner body 5.

掃除機本体５は、吸込具２に塵埃を吸い込むための気流を発生させる電動送風機５ａと、塵埃を含む空気から塵埃を分離する塵埃分離部とを内蔵している。掃除機本体５の塵埃分離部は、例えば、サイクロン式のものでもよいし、紙パック式のものでもよい。   The vacuum cleaner main body 5 includes an electric blower 5a that generates an air flow for sucking dust into the suction tool 2 and a dust separation unit that separates dust from air containing dust. The dust separation part of the cleaner body 5 may be, for example, a cyclone type or a paper pack type.

使用者が電気掃除機１を用いて掃除を行うとき、使用者はハンドル６を把持する。ハンドル６の近くに、使用者が手で操作するスイッチなどを有する操作部７が設置されている。   When the user performs cleaning using the electric vacuum cleaner 1, the user holds the handle 6. An operation unit 7 having a switch or the like that is operated by a user's hand is installed near the handle 6.

図２は、図１に示す電気掃除機１が備える吸込具２を斜め上から見た斜視図である。図３は、図２に示す吸込具２の断面図である。これらの図に示すように、吸込具２は、ボディー８と連結管９とを備える。連結管９は、ボディー８の長手方向の中央において、ボディー８の後面側に配置されている。連結管９は、前述した吸引パイプ３に対して連結される。吸込具２は、例えば床面のような被清掃面の上を移動しながら塵埃を空気と一緒に吸い込むためのものである。本実施の形態の吸込具２は、掃除機ヘッドとも呼ばれる。   FIG. 2 is a perspective view of the suction tool 2 provided in the electric vacuum cleaner 1 shown in FIG. FIG. 3 is a cross-sectional view of the suction tool 2 shown in FIG. As shown in these drawings, the suction tool 2 includes a body 8 and a connecting pipe 9. The connecting tube 9 is disposed on the rear surface side of the body 8 in the center in the longitudinal direction of the body 8. The connecting pipe 9 is connected to the suction pipe 3 described above. The suction tool 2 is for sucking dust together with air while moving on a surface to be cleaned such as a floor surface. The suction tool 2 of this Embodiment is also called a cleaner head.

ボディー８は、上ケース８ａと下ケース８ｂとが組み合わされて構成された細長い形状の外観を有する。ボディー８の長手方向の長さは、例えば、１０ｃｍ以上３０ｃｍ以下の範囲にあってもよい。図３に示すように、ボディー８は、底面開口８ｃ及び内部空間８ｄを有する。含塵空気が底面開口８ｃからボディー８の内部に流入する。内部空間８ｄは、底面開口８ｃに連通している。含塵空気は、内部空間８ｄを通過して、連結管９の内部へ移動する。   The body 8 has an elongated external appearance configured by combining an upper case 8a and a lower case 8b. The length of the body 8 in the longitudinal direction may be, for example, in the range of 10 cm to 30 cm. As shown in FIG. 3, the body 8 has a bottom surface opening 8c and an internal space 8d. Dust-containing air flows into the body 8 from the bottom surface opening 8c. The internal space 8d communicates with the bottom opening 8c. The dust-containing air passes through the internal space 8d and moves into the connecting pipe 9.

内部空間８ｄに回転清掃体１０が配置されている。回転清掃体１０は、回転可能である。回転清掃体１０は、被清掃面に接する毛１０ａを有する。毛１０ａは、例えばナイロンのような樹脂材料で作られた繊維質の多数のブラシ毛でもよい。回転清掃体１０が回転すると、毛１０ａが被清掃面上の塵埃を掻き上げる。回転清掃体１０は、アジテーターまたはビーターバーとも呼ばれる。   The rotary cleaning body 10 is disposed in the internal space 8d. The rotary cleaning body 10 is rotatable. The rotary cleaning body 10 has hairs 10a in contact with the surface to be cleaned. The bristles 10a may be a large number of fibrous bristles made of a resin material such as nylon. When the rotary cleaning body 10 rotates, the hair 10a scrapes up dust on the surface to be cleaned. The rotary cleaning body 10 is also called an agitator or a beater bar.

ボディー８は、ボディー８の前面を形成する前面壁８ｅを備える。連結管９は、関節１１を介してボディー８につながっている。関節１１により、連結管９は、ボディー８に対して、互いに平行でない第一回転軸及び第二回転軸を中心として回転可能である。   The body 8 includes a front wall 8 e that forms the front surface of the body 8. The connecting tube 9 is connected to the body 8 through a joint 11. The joint 11 allows the connecting tube 9 to rotate with respect to the body 8 about the first rotation axis and the second rotation axis that are not parallel to each other.

図２に示すように、吸込具２は、回転清掃体１０を回転させるモータ１２を備える。モータ１２は、ボディー８の内部に配置されている。モータ１２の駆動力は、例えばベルト（図示せず）のような動力伝達機構を介して回転清掃体１０に伝達され、回転清掃体１０を回転させる。回転清掃体１０の回転軸は、ボディー８の長手方向に対して実質的に平行である。   As shown in FIG. 2, the suction tool 2 includes a motor 12 that rotates the rotary cleaning body 10. The motor 12 is disposed inside the body 8. The driving force of the motor 12 is transmitted to the rotary cleaning body 10 via a power transmission mechanism such as a belt (not shown), for example, and rotates the rotary cleaning body 10. The rotational axis of the rotary cleaning body 10 is substantially parallel to the longitudinal direction of the body 8.

図３に示すように、第一車輪１３及び第二車輪１４がボディー８に対して取り付けられている。ボディー８は、被清掃面上で第一車輪１３に支えられることで、被清掃面上をスムーズに移動できる。第二車輪１４は、ボディー８に対して回動可能な支持部材（図示せず）を介してボディー８に対して取り付けられている。当該支持部材が回動することで、第二車輪１４はボディー８に対して変位可能である。吸込具２が被清掃面から浮いている状態においては、第二車輪１４は、ボディー８の底面から下へ突出する。吸込具２が被清掃面に置かれている状態においては、第二車輪１４は、ボディー８の内側に引っ込む。吸込具２は、第二車輪１４が引っ込んだときにはオンとなり、第二車輪１４が突出したときにはオフとなる安全スイッチ（図示せず）を内蔵している。この安全スイッチがオンすると回転清掃体１０は駆動可能な状態になり、安全スイッチがオフすると回転清掃体１０の回転が停止する。   As shown in FIG. 3, the first wheel 13 and the second wheel 14 are attached to the body 8. The body 8 can be smoothly moved on the surface to be cleaned by being supported by the first wheel 13 on the surface to be cleaned. The second wheel 14 is attached to the body 8 via a support member (not shown) that can rotate with respect to the body 8. The second wheel 14 can be displaced with respect to the body 8 by rotating the support member. In a state where the suction tool 2 is floating from the surface to be cleaned, the second wheel 14 protrudes downward from the bottom surface of the body 8. In a state where the suction tool 2 is placed on the surface to be cleaned, the second wheel 14 is retracted inside the body 8. The suction tool 2 incorporates a safety switch (not shown) that is turned on when the second wheel 14 is retracted and turned off when the second wheel 14 protrudes. When the safety switch is turned on, the rotary cleaning body 10 becomes drivable, and when the safety switch is turned off, the rotation of the rotary cleaning body 10 is stopped.

モータ１２は、回転清掃体１０を回転させる駆動部の例である。この例に代えて、回転清掃体１０を回転させる駆動部は、例えば、空気流によって回転するタービンを用いたものでもよい。   The motor 12 is an example of a drive unit that rotates the rotary cleaning body 10. It replaces with this example, and the drive part which rotates the rotary cleaning body 10 may use the turbine rotated by an airflow, for example.

図４は、図３の一部を拡大した断面図である。図４に示すように、吸込具２は、前面壁８ｅに取り付けられた複数の毛を有する前面植毛部８ｇを備える。前面植毛部８ｇの複数の毛は、前面壁８ｅの下端８ｈよりも下へ突出している。前面植毛部８ｇの複数の毛は、真っ直ぐ下に向かって延びている。前面植毛部８ｇは、複数の毛の上端部すなわち根元部を保持する保持部を有する。なお、図４では、便宜上、前面植毛部８ｇの断面を斜線のハッチングで表している。   FIG. 4 is an enlarged cross-sectional view of a part of FIG. As shown in FIG. 4, the suction tool 2 includes a front flocking portion 8g having a plurality of hairs attached to the front wall 8e. The plurality of bristles of the front flocking portion 8g protrude below the lower end 8h of the front wall 8e. The plurality of bristles of the front flocking portion 8g extend straight downward. The front flocking portion 8g has a holding portion that holds the upper end portions, that is, the root portions, of the plurality of hairs. In addition, in FIG. 4, the cross section of the front flocked part 8g is represented by hatching for convenience.

吸込具２の内部空間８ｄの真空度を高める観点からは、前面壁８ｅの下端８ｈの位置が低いことが望ましい。しかしながら、前面壁８ｅの下端８ｈの位置が低いと、吸込具２の前にある大きなゴミが前面壁８ｅで弾かれてしまい、その大きなゴミを吸い込むことができない。   From the viewpoint of increasing the degree of vacuum in the internal space 8d of the suction tool 2, it is desirable that the position of the lower end 8h of the front wall 8e is low. However, if the position of the lower end 8h of the front wall 8e is low, large dust in front of the suction tool 2 is bounced by the front wall 8e, and the large dust cannot be sucked.

以下の説明では、水平で平坦な被清掃面を「水平清掃面」と称する。水平清掃面を吸込具２が清掃する状態では、前面壁８ｅの下端８ｈと水平清掃面との間の隙間が前面植毛部８ｇによって少なくとも部分的に塞がれる。これにより、以下の効果が得られる。前面壁８ｅの下端８ｈと水平清掃面との間の隙間が前面植毛部８ｇによって塞がれることで、吸込具２の内部空間８ｄの真空度を高めることができる。このため、優れた吸引性能が得られる。前面植毛部８ｇは、容易に変形可能であるので、吸込具２の前にある大きなゴミは、前面植毛部８ｇを通過して底面開口８ｃに容易に到達できる。このため、その大きなゴミを確実に吸い込むことができる。壁際を掃除するときには、前面壁８ｅが壁に接するようにすることで、壁と床との間の角部のゴミを確実に吸い取ることができる。   In the following description, a horizontal and flat surface to be cleaned is referred to as a “horizontal cleaning surface”. In the state where the suction tool 2 cleans the horizontal cleaning surface, the gap between the lower end 8h of the front wall 8e and the horizontal cleaning surface is at least partially blocked by the front flocking portion 8g. Thereby, the following effects are acquired. Since the gap between the lower end 8h of the front wall 8e and the horizontal cleaning surface is blocked by the front flocking portion 8g, the degree of vacuum of the internal space 8d of the suction tool 2 can be increased. Therefore, excellent suction performance can be obtained. Since the front flocking portion 8g can be easily deformed, large dust in front of the suction tool 2 can easily reach the bottom surface opening 8c through the front flocking portion 8g. For this reason, the big garbage can be sucked in reliably. When cleaning the wall, the front wall 8e is in contact with the wall, so that the dust at the corner between the wall and the floor can be surely sucked.

水平清掃面を吸込具２が清掃する状態で、前面植毛部８ｇの下端は、水平清掃面に接してもよい。また、水平清掃面を吸込具２が清掃する状態で、前面植毛部８ｇの下端と水平清掃面との間に僅かな隙間があってもよい。   In a state where the suction tool 2 cleans the horizontal cleaning surface, the lower end of the front flocking portion 8g may be in contact with the horizontal cleaning surface. Moreover, in the state where the suction tool 2 cleans the horizontal cleaning surface, there may be a slight gap between the lower end of the front flocking portion 8g and the horizontal cleaning surface.

前面植毛部８ｇは、底面開口８ｃの長手方向に沿って、底面開口８ｃのほぼ全長に渡って形成されていることが望ましい。   It is desirable that the front flocked portion 8g is formed over almost the entire length of the bottom surface opening 8c along the longitudinal direction of the bottom surface opening 8c.

前面壁８ｅは、少なくとも一部が、例えばエラストマー、塩化ビニールのような、比較的変形し易い軟質材料で作られていることが望ましい。そのようにすることで、以下の効果が得られる。吸込具２の前にある大きなゴミが前面植毛部８ｇを通過するときに、前面植毛部８ｇだけでなく前面壁８ｅが変形することで、大きなゴミがさらに容易に底面開口８ｃに到達できる。このため、その大きなゴミをより確実に吸い込むことができる。   It is desirable that at least a part of the front wall 8e is made of a soft material that is relatively easily deformed, such as an elastomer or vinyl chloride. By doing so, the following effects can be obtained. When large dust in front of the suction tool 2 passes through the front flocking portion 8g, not only the front flocking portion 8g but also the front wall 8e is deformed, so that large dust can reach the bottom surface opening 8c more easily. For this reason, the big garbage can be sucked in more reliably.

図５は、図４に対する変形例を示す断面図である。図５に示す変形例の吸込具２では、ボディー８を側面から見たときに、前面植毛部８ｇの複数の毛の突出方向が、ボディー８の後方に向かって斜め下となる方向になっている。この変形例によれば、以下の効果が得られる。吸込具２の前にある大きなゴミが、前面植毛部８ｇをさらに容易に通過することができる。このため、その大きなゴミをより確実に吸い込むことができる。   FIG. 5 is a cross-sectional view showing a modification of FIG. In the suction tool 2 of the modified example shown in FIG. 5, when the body 8 is viewed from the side, the protruding direction of the plurality of hairs of the front flocking portion 8 g is obliquely downward toward the rear of the body 8. Yes. According to this modification, the following effects can be obtained. Large garbage in front of the suction tool 2 can pass through the front flocking part 8g more easily. For this reason, the big garbage can be sucked in more reliably.

前面植毛部８ｇの毛は、柔軟であることが望ましい。前面植毛部８ｇの毛が柔軟であれば、吸込具２の前にある大きなゴミが前面植毛部８ｇを容易に通過することができるからである。この観点から、前面植毛部８ｇの毛は、回転清掃体１０の毛１０ａよりも柔軟であることが望ましい。具体的には、前面植毛部８ｇの毛が、回転清掃体１０の毛１０ａのうちで最も曲げ剛性の高い毛よりも低い曲げ剛性を有する第一条件と、前面植毛部８ｇの毛の太さが、回転清掃体１０の毛１０ａのうちで最も太い毛よりも細い第二条件と、前面植毛部８ｇの毛の長さが、回転清掃体１０の毛１０ａのうちで最も短い毛よりも長い第三条件のうちの少なくとも一つの条件を満足することが望ましい。そのようにすることで、前面植毛部８ｇの毛が柔軟になり、上記の効果をより確実に奏することが可能となる。   It is desirable that the hair of the front flocking portion 8g be flexible. This is because if the hair of the front flocking portion 8g is flexible, large dust in front of the suction tool 2 can easily pass through the front flocking portion 8g. From this viewpoint, it is desirable that the hair of the front flocking portion 8g is more flexible than the hair 10a of the rotary cleaning body 10. Specifically, the first condition that the hair of the front flocking portion 8g has lower bending rigidity than the hair having the highest bending rigidity among the bristles 10a of the rotary cleaning body 10, and the thickness of the hair of the front flocking portion 8g. However, the second condition that is thinner than the thickest hair among the hairs 10a of the rotary cleaning body 10 and the length of the hair of the front flocking portion 8g are longer than the shortest hair among the hairs 10a of the rotary cleaning body 10 It is desirable to satisfy at least one of the third conditions. By doing so, the hair of the front flocking part 8g becomes flexible, and the above-described effects can be more reliably exhibited.

図６は、実施の形態１による電気掃除機１の機能ブロック図である。図６に示すように、電気掃除機１は、制御部１６を備える。制御部１６は、操作部７から受信した信号に基づいて、電動送風機５ａ及びモータ１２の運転を制御する。制御部１６は、電動送風機５ａの出力を調整することにより電動送風機５ａの吸引力を調整できる。制御部１６は、モータ１２により回転清掃体１０の回転速度を調整できる。制御部１６は、処理回路により実現されてもよい。制御部１６の処理回路は、少なくとも１つのプロセッサ１６ａと少なくとも１つのメモリ１６ｂとを備えてもよい。   FIG. 6 is a functional block diagram of the electric vacuum cleaner 1 according to the first embodiment. As shown in FIG. 6, the vacuum cleaner 1 includes a control unit 16. The control unit 16 controls the operation of the electric blower 5 a and the motor 12 based on the signal received from the operation unit 7. The controller 16 can adjust the suction force of the electric blower 5a by adjusting the output of the electric blower 5a. The control unit 16 can adjust the rotation speed of the rotary cleaning body 10 by the motor 12. The control unit 16 may be realized by a processing circuit. The processing circuit of the control unit 16 may include at least one processor 16a and at least one memory 16b.

本実施の形態の電気掃除機１では、電動送風機５ａを最大出力で運転したときに吸込具２を通過する空気の流量は、１．０ｍ３／ｍｉｎ以下でもよい。本実施の形態であれば、そのような比較的低い空気流量の場合でも、前面植毛部８ｇを備えたことで、吸込具２の内部空間８ｄの真空度を十分に高めることができる。 In the electric vacuum cleaner 1 of this Embodiment, 1.0 m < 3 > / min or less may be sufficient as the flow volume of the air which passes the suction tool 2 when the electric blower 5a is drive | operated by the maximum output. If it is this Embodiment, even in the case of such a comparatively low air flow rate, the vacuum degree of the internal space 8d of the suction tool 2 can fully be raised by providing the front flocking part 8g.

実施の形態２．
次に、図７及び図８を参照して、実施の形態２について説明するが、前述した実施の形態１との相違点を中心に説明し、同一部分または相当部分については説明を簡略化または省略する。図７は、実施の形態２による吸込具２の底面図である。図８は、実施の形態２による吸込具２の側面図である。 Embodiment 2. FIG.
