Description

本発明は、集塵袋を搭載した電気掃除機に関する。   The present invention relates to an electric vacuum cleaner equipped with a dust bag.

近年の電気掃除機は、様々なタイプのものが存在する。一般的な家庭用電気掃除機は大別すると、吸引したゴミを袋状になった集塵袋で濾し取る集塵袋式と、コーン状の筒の中で空気を回転させ遠心力により空気とゴミを分離するサイクロン式とに分けられる。   There are various types of vacuum cleaners in recent years. Generally, household vacuum cleaners are roughly classified into a dust bag type that filters out sucked dust with a bag-shaped dust bag, and air is rotated by centrifugal force by rotating air in a cone-shaped tube. It is divided into a cyclone type that separates garbage.

集塵袋式の電気掃除機として、例えば、特許文献1には、「電気掃除機本体の集塵室内の集塵袋上面をたたく除塵手段を設けた電気掃除機」が開示されている。特許文献1の電気掃除機によれば、塵埃を吸引した際の集塵袋の目詰まりを防止する為に、前記除塵手段は、前記集塵袋の上面に配置され、前記除塵手段は前記集塵袋の上面の前後を叩く、叩き部材と、その叩き部材を駆動する為の駆動用モータと、前記駆動用モータから動力を伝達するカムを有して構成されている。   As a dust bag type electric vacuum cleaner, for example, Patent Document 1 discloses "an electric vacuum cleaner provided with a dust removing means for striking the upper surface of the dust collecting bag in the dust collecting chamber of the electric vacuum cleaner body". According to the electric vacuum cleaner of Patent Document 1, in order to prevent clogging of the dust collecting bag when dust is sucked, the dust removing means is arranged on the upper surface of the dust collecting bag, and the dust removing means is provided with the dust collecting means. The dust bag includes a striking member for striking the front and rear of the upper surface of the dust bag, a driving motor for driving the striking member, and a cam for transmitting power from the driving motor.

特開2007-111352号公報JP, 2007-111352, A

しかしながら、特許文献1の方法では、集塵袋を振動させ、除塵を行う除塵手段を、叩き部材、駆動用モータ、動力伝達のカムで構成し、且つ強度を確保する為、前記部品を一体とする為にケースで覆う必要があった。この為、除塵手段が大型化し、集塵袋の集塵容積が小さくなり、また重量も重くなってしまう恐れがある。   However, in the method of Patent Document 1, the dust removing means for vibrating the dust collecting bag to remove the dust is composed of a striking member, a drive motor, and a power transmission cam, and in order to secure the strength, the parts are integrated. I had to cover it with a case to do it. Therefore, there is a possibility that the dust removing means becomes large, the dust collecting volume of the dust collecting bag becomes small, and the weight becomes heavy.

さらに、前記除塵機構は外郭がケースで覆われていることで、除塵機構を通過する空気の流れが発生しづらい。この為、塵埃を吸引した場合に、集塵袋が前記除塵部材に張り付いてしまい、集塵袋と前記除塵部材との間で風の流れる空間が減少し、吸引力が低下する原因となる恐れがある。   Further, since the outer casing of the dust removing mechanism is covered with the case, it is difficult for the air flow passing through the dust removing mechanism to occur. Therefore, when the dust is sucked, the dust collecting bag sticks to the dust removing member, and the space in which the air flows between the dust collecting bag and the dust removing member decreases, which causes the suction force to decrease. There is a fear.

また、空気が通るように前記除塵機構に穴をあける為には同時に強度の確保が必要となるが、特許文献1に記載のような形状では強度を確保する為に多数のリブを必要とする恐れがある。その場合、十分な開口面積を確保することが困難となる恐れがある。   Further, it is necessary to secure strength at the same time in order to make a hole in the dust removing mechanism so that air can pass through, but in the shape as described in Patent Document 1, a large number of ribs are required to secure strength. There is a fear. In that case, it may be difficult to secure a sufficient opening area.

そこで、本発明の目的は、上記問題を解決し、小型・軽量で必要十分な強度を有し、かつ、通気性に優れ、吸引性能が低下し難い除塵手段を備えた集塵袋式の電気掃除機を提供することにある。   Therefore, an object of the present invention is to solve the above-mentioned problems, to provide a dust-collecting bag-type electric machine that is compact and lightweight, has necessary and sufficient strength, is excellent in breathability, and has a dust removing means that does not easily deteriorate suction performance. To provide a vacuum cleaner.

また、本発明の目的は、掃除機本体における集塵室の容量をできるだけ大きくし、大容量の集塵袋式の電気掃除機を提供することにある。   Another object of the present invention is to provide a large-capacity dust bag type electric vacuum cleaner in which the capacity of the dust collecting chamber in the cleaner body is as large as possible.

上記課題を解決するために、本発明は、電動送風機および集塵室を有する掃除機本体と、前記集塵室内に配置された集塵袋と、前記集塵室を開閉する蓋体を備えた電気掃除機において、前記集塵袋は、略板形状の支持部と該支持部の一端に位置し略コの字形状をしている保持部と前記保持部の端部に位置し略板形状のリブと前記リブの端部に前記リブと直行するように位置し略板形状をしている本体支持部と、を有し、平面視で略Y字形状の集塵袋保持部材に保持され、前記集塵室内の前記集塵袋の上部に配置され、流路構成部材は集塵袋を潰す方向、もしくは振動する方向に動作可能に配置された除塵部材を有し、
前記除塵部材はハニカム構造で形成された通気穴と、前記除塵部材と前記蓋体の間に流路空間を有し、前記除塵部材は、平面視で略凹形状であり、前記除塵部材は前記蓋体に沿うような曲面を有し、前記曲面から前記集塵袋の側に最も突出した形状が、前記除塵部材を支持する軸部から最も遠い位置に配置され、前記除塵部材が回転軸を中心に前記集塵袋の位置する下方向に動作し、前記略凹形状の左右の凸部分の先端部に設けた前記突起により、前記集塵袋を叩き、前記突起が、前記集塵袋保持部材の略Y字形状の脇の部分である前記支持部に隣接するよう位置することを特徴とする。
In order to solve the above problems, the present invention includes a cleaner body having an electric blower and a dust collection chamber, a dust collection bag arranged in the dust collection chamber, and a lid body that opens and closes the dust collection chamber. In the vacuum cleaner, the dust collecting bag has a substantially plate-shaped supporting portion, a holding portion located at one end of the supporting portion and having a substantially U- shape , and a substantially plate-shaped supporting portion located at an end portion of the holding portion. And a main body supporting portion having a substantially plate shape which is positioned so as to be orthogonal to the rib at an end portion of the rib, and is held by a dust collecting bag holding member having a substantially Y shape in a plan view. A dust removing member disposed in an upper portion of the dust collecting bag in the dust collecting chamber, wherein the flow path forming member is arranged so as to be operable in a direction of crushing the dust collecting bag or in a vibrating direction.
The dust removing member has a vent hole formed of a honeycomb structure, and has a flow path space between the dust removing member and the lid, the dust removing member is substantially concave in plan view, the dust removing member is the Having a curved surface along the lid, the shape that most protrudes from the curved surface to the side of the dust collecting bag is arranged at a position farthest from the shaft portion that supports the dust removing member, and the dust removing member rotates the rotating shaft.

以下、図面を用いて本発明の実施例を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

先ず初めに、図1乃至図7を用いて、本発明の一実施形態における電気掃除機について説明する。   First, an electric vacuum cleaner according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7.

図1は、本発明を用いた集塵袋式の電気掃除機を斜め前方から見た全体斜視図である。   FIG. 1 is an overall perspective view of a dust bag type electric vacuum cleaner using the present invention as seen obliquely from the front.

本発明における電気掃除機1は、本体ケース3の後面側に位置する電動送風機と、本体ケース3の前面側に位置する集塵室16と、を有する掃除機本体2を備えている。   The electric vacuum cleaner 1 according to the present invention includes a cleaner main body 2 having an electric blower located on the rear surface side of the main body case 3 and a dust collection chamber 16 located on the front surface side of the main body case 3.

更に、図1に示すように、本発明における電気掃除機1は、本体ケース3にハンドル5が備え付けられており、電気掃除機1を移動する際に、ハンドル5を把持し持ち運ぶことが可能な構造となっている。   Further, as shown in FIG. 1, the electric vacuum cleaner 1 according to the present invention is provided with the handle 5 in the main body case 3, and when the electric vacuum cleaner 1 is moved, the handle 5 can be grasped and carried. It has a structure.

また、本体ケース3には走行車輪6が設けられており、電気掃除機1を使用する際に前後左右自在に掃除機本体2を移動することができる。   Further, the main body case 3 is provided with traveling wheels 6, and the vacuum cleaner main body 2 can be freely moved back and forth and left and right when the electric vacuum cleaner 1 is used.

本体ケース3の前面側上部には蓋4が開閉可能に取り付けられており、蓋4を開けることにより、電気掃除機1の内部すなわち後述する集塵室16が開放状態となる。   A lid 4 is attached to the upper part of the front surface side of the main body case 3 so as to be openable and closable, and by opening the lid 4, the inside of the electric vacuum cleaner 1, that is, a dust collection chamber 16 described later is opened.

蓋4には、蓋4を貫通するホース接続口7が設けられている。このホース接続口7は、電気掃除機1の外部と集塵室16とを連通するように形成されている。   The lid 4 is provided with a hose connection port 7 penetrating the lid 4. The hose connection port 7 is formed so as to connect the outside of the electric vacuum cleaner 1 to the dust collection chamber 16.

ホース接続口7には、図示しない電気掃除機用ホースが回転自在に接続され、電気掃除機1の使用時に、電気掃除機用ホースを介して吸引されたゴミや塵、埃が集塵室16内へ吸い込まれる。   A hose for an electric vacuum cleaner (not shown) is rotatably connected to the hose connection port 7, and when the electric vacuum cleaner 1 is used, dust, dirt, and dust sucked through the hose for the electric vacuum cleaner are collected in the dust collection chamber 16 Is sucked in.

ここで、本実施例において説明する電気掃除機1は、上記のように電気掃除機用ホースが電気掃除機1に回転自在に接続されるスイーベル掃除機を例に用いているが、本発明はスイーベル掃除機に限定されるものではなく、集塵袋式の電気掃除機であれば、他のタイプの掃除機にも適用することもできる。   Here, the electric vacuum cleaner 1 described in the present embodiment uses as an example a swivel cleaner in which the electric vacuum cleaner hose is rotatably connected to the electric vacuum cleaner 1 as described above. The vacuum cleaner is not limited to the swivel cleaner, but can be applied to other types of vacuum cleaners as long as it is a dust bag type vacuum cleaner.

また、蓋4には電気掃除機1の吸引状態(吸引力)を表示するインジケータ8が設けられており、吸引状態(吸引力)をユーザが目視で確認することができる。   Further, the lid 4 is provided with an indicator 8 for displaying the suction state (suction force) of the vacuum cleaner 1, and the user can visually confirm the suction state (suction force).

例えば、集塵室内に吸引されたゴミが一杯になったり、集塵室16内の集塵袋21が目詰まりして吸引力が低下した場合、このインジケータ8により吸引力の低下を確認することができる。   For example, if the dust sucked into the dust collection chamber is full or the dust collection bag 21 in the dust collection chamber 16 is clogged and the suction force is reduced, the indicator 8 is used to confirm the reduction of the suction force. You can

蓋4には窓9が設けられており、電気掃除機1の外部から集塵室16内部の状態を目視で確認することができる。   The lid 4 is provided with a window 9 so that the state inside the dust collection chamber 16 can be visually confirmed from the outside of the electric vacuum cleaner 1.

本体ケース3の後面側上部には、排気口11が設けられている。図1には図示していないが、本体ケース3の後面側すなわち集塵室16の後ろ側には電動送風機が設けられている。この電動送風機を起動することにより、掃除機本体2内部において、ホース接続口7から排気口11に向かう気流が生じる。   An exhaust port 11 is provided on the upper rear side of the body case 3. Although not shown in FIG. 1, an electric blower is provided on the rear surface side of the main body case 3, that is, the rear side of the dust collection chamber 16. By activating this electric blower, an air flow from the hose connection port 7 to the exhaust port 11 is generated inside the cleaner main body 2.

ホース接続口7から吸引された空気は、集塵室16、電動送風機を介して掃除機本体2内部を流れ、排気口11から掃除機本体2の外部へと排出される。   The air sucked from the hose connection port 7 flows inside the cleaner body 2 via the dust collection chamber 16 and the electric blower, and is discharged to the outside of the cleaner body 2 from the exhaust port 11.

また、本体ケース3の後面側上部には、吸引力調整つまみ10が設けられている。この吸引力調整つまみ10により、吸引力(電動送風機の回転数)を調整することができる。   A suction force adjusting knob 10 is provided on the upper rear side of the body case 3. The suction force adjusting knob 10 can adjust the suction force (the rotation speed of the electric blower).

本体ケース3の後面側上部には、電源ボタン12や電源コード巻取ボタン13なども設けられている。   A power button 12, a power cord winding button 13, and the like are also provided on the upper rear side of the body case 3.

図2は、本発明を用いた集塵袋式の電気掃除機を斜め後方から見た全体斜視図である。   FIG. 2 is an overall perspective view of a dust bag type electric vacuum cleaner using the present invention as seen obliquely from the rear.

本実施例における電気掃除機1には、後面側にブロアー機能用接続口14と、ブロアー機能用接続口14が開閉可能となるように設けられるブロアー機能用蓋15と、が設けられている。   The electric vacuum cleaner 1 in the present embodiment is provided with a blower function connection port 14 on the rear surface side and a blower function cover 15 provided so that the blower function connection port 14 can be opened and closed.

このブロアー機能用接続口14は、電気掃除機1を停止している場合や、電気掃除機1を塵埃を吸引するために使用する場合は、ブロアー機能用蓋15により閉塞されている。この場合、電動送風機の後流は全て排気口11から掃除機本体2の外部へと排気される。   The blower function connection port 14 is closed by a blower function cover 15 when the electric vacuum cleaner 1 is stopped or when the electric vacuum cleaner 1 is used for sucking dust. In this case, the wake of the electric blower is exhausted from the exhaust port 11 to the outside of the cleaner body 2.

電気掃除機1を塵埃を吹き飛ばすために使用する場合、つまり電気掃除機1をブロアーとして使用する場合には、このブロアー機能用接続口14にホースや管を接続して使用する。ブロアー機能用接続口14にホースや管を接続するときは次のように行う。   When the electric vacuum cleaner 1 is used for blowing out dust, that is, when the electric vacuum cleaner 1 is used as a blower, a hose or a pipe is connected to the blower function connection port 14 for use. When connecting a hose or a tube to the blower function connection port 14, the procedure is as follows.

ホースや管によって、電気掃除機1の外側からブロアー機能用蓋15を押すことで、ブロアー機能用蓋15を回動させる。ブロアー機能用蓋15を回動させることにより、ブロアー機能用接続口14を開放し、ホースや管とブロアー機能用接続口14とを接続する。   By pushing the blower function lid 15 from the outside of the electric vacuum cleaner 1 with a hose or a tube, the blower function lid 15 is rotated. By rotating the blower function lid 15, the blower function connection port 14 is opened, and the hose or pipe is connected to the blower function connection port 14.

ホースや管により回動されたブロアー機能用蓋15は、電気掃除機1の内部で電動送風機から排気口11への流路を塞ぐ役割を果たす。ホースや管の接続によるブロアーとしての使用への自動切り替えにより、排気口11から排出されていた空気(排気)の一部或いは全部をブロアー機能用接続口14から掃除機本体2の外部へ排出し、電気掃除機1をブロアーとして使用することができる。   The blower function lid 15 rotated by a hose or a tube plays a role of blocking a flow path from the electric blower to the exhaust port 11 inside the electric vacuum cleaner 1. By automatically switching to use as a blower by connecting a hose or a pipe, a part or all of the air (exhaust air) discharged from the exhaust port 11 is discharged to the outside of the cleaner body 2 from the blower function connection port 14. The vacuum cleaner 1 can be used as a blower.

図3は、本実施例の電気掃除機1において、蓋4を開けて集塵室16を開放した状態を示している。図3は、集塵室16の内部構造が分かり易いよう、集塵袋21を装着していない状態を示している。   FIG. 3 shows a state in which the lid 4 is opened and the dust collection chamber 16 is opened in the electric vacuum cleaner 1 of the present embodiment. FIG. 3 shows a state in which the dust collecting bag 21 is not attached so that the internal structure of the dust collecting chamber 16 can be easily understood.

図示しない電動送風機と集塵室16との境界部分すなわち集塵室16の後面側かつ電動送風機の前面側には、保護フィルター18が設けられている。蓋4の内側には塵落とし部材19が設けられている。塵落とし部材19については後記する。   A protective filter 18 is provided on the boundary between the electric blower (not shown) and the dust collection chamber 16, that is, on the rear side of the dust collection chamber 16 and the front side of the electric blower. A dust removing member 19 is provided inside the lid 4. The dust removing member 19 will be described later.

集塵室16内には、集塵袋21を保持する集塵袋保持部材20が設けられている。   A dust collection bag holding member 20 that holds a dust collection bag 21 is provided in the dust collection chamber 16.

図4Aは、集塵袋保持部材20の斜視図である。集塵袋保持部材20は、支持部20aと、保持部20bと、リブ20cと、本体支持部20dと、を有する。支持部20aは略板形状をしている。保持部20bは、支持部20aの一端に位置し、略コの字形状をしている。リブ20cは、保持部20bの端部に位置し、略板形状をしている。本体接触部20dは、リブ20cの端部にリブ20cと直交するように位置し、略板形状をしている。   FIG. 4A is a perspective view of the dust collecting bag holding member 20. The dust collecting bag holding member 20 has a supporting portion 20a, a holding portion 20b, a rib 20c, and a main body supporting portion 20d. The support portion 20a has a substantially plate shape. The holding portion 20b is located at one end of the support portion 20a and has a substantially U shape. The rib 20c is located at the end of the holding portion 20b and has a substantially plate shape. The main body contact portion 20d is located at an end of the rib 20c so as to be orthogonal to the rib 20c and has a substantially plate shape.

図4Bは、集塵袋保持部材20の平面図である。集塵袋保持部材20は、平面視で略Y字形状となっている。   FIG. 4B is a plan view of the dust bag holding member 20. The dust collecting bag holding member 20 has a substantially Y shape in a plan view.

図5に示すように、集塵袋保持部材20は、支持部20aにおける保持部20bとは反対側の端部で、本体ケース3における集塵室16の後面側の上部付近(保護フィルター18の上部付近)に回動可能となるように取り付けられている。   As shown in FIG. 5, the dust collecting bag holding member 20 is at an end portion of the support portion 20a opposite to the holding portion 20b, and near the upper portion on the rear surface side of the dust collecting chamber 16 in the main body case 3 (of the protection filter 18). It is attached so that it can be rotated (near the upper part).

集塵袋保持部材20が回動可能であるため、集塵袋21を取り付ける際に集塵袋保持部材20が邪魔とならず、取り付け易いという効果を奏する。   Since the dust collecting bag holding member 20 is rotatable, the dust collecting bag holding member 20 does not get in the way when the dust collecting bag 21 is attached, and the dust collecting bag holding member 20 is easily attached.

また、本実施例における集塵袋保持部材20は、図4に示すように、支持部20aにおける保持部20bとは反対側の端部がバネを介して本体ケース3に取り付けられている。バネを介して取り付けられていることにより、図3や図5に示すように、集塵袋保持部材20に集塵袋21が取り付けられていない状態において、支持部20aにおける保持部20bとは反対側の端部を軸として集塵袋保持部材20が上方へ付勢されている。   Further, as shown in FIG. 4, the dust bag holding member 20 in this embodiment has an end portion of the support portion 20a opposite to the holding portion 20b attached to the main body case 3 via a spring. Since the dust collecting bag 21 is not attached to the dust collecting bag holding member 20 as shown in FIGS. 3 and 5 by being attached via the spring, it is opposite to the holding portion 20b of the supporting portion 20a. The dust collecting bag holding member 20 is urged upward with the end portion on the side as an axis.

これにより、集塵袋21を取り付ける際に、集塵袋保持部材20を自ら回動させる必要がなく、更に取り付け易いというという効果を奏する。   Thereby, when attaching the dust collecting bag 21, it is not necessary to rotate the dust collecting bag holding member 20 by itself, and it is easier to attach.

本体接触部20dは、集塵袋保持部材20が下方向に回動された場合に、本体ケース3と接し、集塵袋保持部材20を支持する
保持部20bにおける支持部20aとの連結部の近傍には凸部(突起)27が設けられている。凸部27は、集塵袋21を集塵袋保持部材20に取り付ける際、集塵袋21の口板部21aに設けられた切欠き24に入り、集塵袋保持部材20に対する口板部21aの位置決めとして機能する。
The main body contact portion 20d is in contact with the main body case 3 when the dust collecting bag holding member 20 is rotated downward and supports the dust collecting bag holding member 20. A convex portion (projection) 27 is provided in the vicinity. When attaching the dust collecting bag 21 to the dust collecting bag holding member 20, the convex portion 27 enters the notch 24 provided in the mouth plate portion 21a of the dust collecting bag 21, and the mouth plate portion 21a for the dust collecting bag holding member 20. Function as the positioning of.

更に、集塵袋保持部材20と支持部32の連結部近傍には凸部(突起)28および凸部(突起)29が設けられている。凸部28,29は、凸部27よりも小さく、それぞれ凸部27の左右に位置する。凸部28,29は、集塵袋21を集塵袋保持部材20に装着する際、集塵袋21の口板部21aに設けられた穴25および穴26に嵌合し、集塵袋保持部材20に対する口板部21aの位置決めおよび係止手段として機能する。   Further, a convex portion (projection) 28 and a convex portion (projection) 29 are provided in the vicinity of the connecting portion between the dust bag holding member 20 and the support portion 32. The convex portions 28 and 29 are smaller than the convex portion 27 and are located on the left and right sides of the convex portion 27, respectively. When the dust collecting bag 21 is attached to the dust collecting bag holding member 20, the convex portions 28 and 29 are fitted into the holes 25 and 26 provided in the mouth plate portion 21a of the dust collecting bag 21 to hold the dust collecting bag. It functions as a positioning and locking means for the mouth plate 21a with respect to the member 20.

保持部20bの内側で支持部20aとは反対側には、傾斜部35が延在して設けられている。   An inclined portion 35 is provided so as to extend inside the holding portion 20b and on the side opposite to the support portion 20a.

保持部20bの内側で略コの字型の両側には、ガイドレール30が延在して設けられている。傾斜部35、ガイドレール30については、後記する。   Guide rails 30 are provided so as to extend inside the holding portion 20b on both sides of the substantially U-shape. The inclined portion 35 and the guide rail 30 will be described later.

ここで、集塵袋保持部材20は、保持部20bの長さSが、支持部20aを含む集塵袋保持部材20の全長Sの半分よりも短くなるように形成されている。つまり、保持部20bの長さSと支持部32を含む集塵袋保持部材20の全長Sとの関係は、S<S/2である。 Here, the dust bag holding member 20 is formed such that the length S 5 of the holding portion 20b is shorter than half of the total length S 4 of the dust bag holding member 20 including the support portion 20a. That is, the relationship between the length S 5 of the holding portion 20b and the total length S 4 of the dust bag holding member 20 including the support portion 32 is S 5 <S 4 /2.

このように、集塵袋保持部材20の全長に対して、集塵袋21を装着する略コの字型の保持部20bの長さを半分以下にすることで、集塵袋保持部材20の重心が集塵袋保持部材20の長さ方向の保持部側に位置し、集塵袋保持部材20に集塵袋21を装着した際に自重で集塵袋保持部材20が降下し易くなるように構成されている。   In this way, the length of the substantially U-shaped holding portion 20b for mounting the dust collecting bag 21 is set to be half or less of the entire length of the dust collecting bag holding member 20, so that the dust collecting bag holding member 20 The center of gravity is located on the holding portion side in the length direction of the dust collecting bag holding member 20, and when the dust collecting bag 21 is attached to the dust collecting bag holding member 20, the dust collecting bag holding member 20 easily falls due to its own weight. Is configured.

図5は、図3における電気掃除機1の前面から後面に跨る横断面を示している。   FIG. 5 shows a cross section extending from the front surface to the rear surface of the electric vacuum cleaner 1 in FIG.

図5のように、集塵袋保持部材20の先が上方向に位置している状態では、そのまま蓋4を回動させ閉めようとしても、集塵袋保持部材20の先が蓋4に接触し、蓋4のそれ以上の回動を防止する。つまり、集塵袋保持部材20に集塵袋21が装着されていない状態では、蓋4を閉めることができない構造となっており、集塵袋21を未装着のまま電気掃除機1を運転することのないようにしている。   As shown in FIG. 5, when the tip of the dust collecting bag holding member 20 is located in the upper direction, even if the lid 4 is rotated and closed as it is, the tip of the dust collecting bag holding member 20 contacts the lid 4. Therefore, the lid 4 is prevented from rotating further. That is, the structure is such that the lid 4 cannot be closed when the dust bag 21 is not attached to the dust bag holding member 20, and the electric vacuum cleaner 1 is operated without the dust bag 21 being attached. I'm trying not to be.

なお、前記のように、集塵袋21を集塵袋保持部材20に装着すると、集塵袋保持部材20が下方向に回動するため、集塵袋21を装着した状態では集塵袋保持部材20の先が蓋4に接触することはない。   As described above, when the dust collecting bag 21 is attached to the dust collecting bag holding member 20, the dust collecting bag holding member 20 is rotated downward, so that the dust collecting bag holding member 20 is attached to the dust collecting bag holding member 20. The tip of the member 20 does not contact the lid 4.

次に図6および図7を用いて、集塵袋保持部材20に集塵袋21が装着される際の状態について説明する。   Next, a state in which the dust bag 21 is attached to the dust bag holding member 20 will be described with reference to FIGS. 6 and 7.

図6は、集塵袋保持部材20に集塵袋21を装着した直後の状態を示している。集塵袋保持部材20に集塵袋21の口板部21aを装着する。集塵袋本体すなわち集塵袋21は、図6に示すように、集塵室16内に収納される。   FIG. 6 shows a state immediately after the dust bag 21 is attached to the dust bag holding member 20. The mouth plate 21a of the dust bag 21 is attached to the dust bag holding member 20. The dust bag main body, that is, the dust bag 21 is housed in the dust collection chamber 16 as shown in FIG.

集塵袋21の口板部21aに設けられた開口23すなわち集塵袋21の吸い込み口が蓋4のホース接続口7と連通するように、集塵袋21の口板部21aが集塵袋保持部材20に装着される。   The mouth plate 21a of the dust collecting bag 21 is connected to the opening 23 provided in the mouth plate 21a of the dust collecting bag 21, that is, the suction port of the dust collecting bag 21 communicates with the hose connection port 7 of the lid 4. It is attached to the holding member 20.

ここで、集塵袋21の口板部21aは、後記するように、集塵袋21の口板部21aに設けられた穴25,26と集塵袋保持部材20に設けられた凸部(突起)28,29が嵌合するように集塵袋保持部材20に装着される。   Here, as will be described later, the mouth plate portion 21a of the dust collecting bag 21 has holes 25 and 26 provided in the mouth plate portion 21a of the dust collecting bag 21 and a convex portion (provided on the dust collecting bag holding member 20). The dust collecting bag holding member 20 is mounted so that the projections 28 and 29 fit together.

上記のように、集塵袋保持部材20は、集塵袋21を装着されていない状態においては、バネにより上方へ付勢して保持されているが、集塵袋21の口板部21aを集塵袋保持部材20に装着すると、集塵袋21の自重により、集塵袋保持部材20、集塵袋21、口板部21aが降下し、集塵室16内に集塵袋21が自動的に装着される。   As described above, the dust collecting bag holding member 20 is urged upward by the spring and held by the spring when the dust collecting bag 21 is not attached. When attached to the dust bag holding member 20, the dust bag holding member 20, the dust bag 21, and the mouth plate portion 21 a descend due to the weight of the dust bag 21, and the dust bag 21 is automatically placed in the dust chamber 16. Will be installed.

つまり、集塵袋21が装着されていない状態においては、集塵袋保持部材20はバネの力により上方へ付勢されて保持されているが、集塵袋保持部材20に集塵袋21を装着すると、集塵袋21の重さがバネの力に勝って、集塵袋保持部材20が降下する。   That is, when the dust bag 21 is not attached, the dust bag holding member 20 is held by being biased upward by the force of the spring, but the dust bag 21 is attached to the dust bag holding member 20. When mounted, the weight of the dust collecting bag 21 exceeds the force of the spring, and the dust collecting bag holding member 20 descends.

集塵袋21に肩落ち部36が設けられているため、集塵袋保持部材20に集塵袋21を装着後、集塵袋保持部材20が降下する際に、集塵室の内壁等にぶつかることがないという効果を奏する。   Since the dust collecting bag 21 is provided with the shoulder drop portion 36, when the dust collecting bag holding member 20 is mounted on the dust collecting bag holding member 20 and then the dust collecting bag holding member 20 descends, the dust collecting bag 21 is attached to the inner wall of the dust collecting chamber or the like. It has the effect of not hitting.

図7は、図6における電気掃除機1の前面から後面に跨る横断面を示している。図7においては、集塵袋保持部材20に集塵袋21が装着され、集塵袋保持部材20が降下し、集塵袋保持部材20の本体接触部20dが本体ケース3と接し、集塵袋保持部材20を支持する状態を示している。図7では、電気掃除機1の全体構成が分かり易いよう、集塵室16に収納される集塵袋21は省略している。   FIG. 7 shows a cross section extending from the front surface to the rear surface of the electric vacuum cleaner 1 in FIG. In FIG. 7, the dust collecting bag 21 is attached to the dust collecting bag holding member 20, the dust collecting bag holding member 20 descends, and the main body contact portion 20d of the dust collecting bag holding member 20 contacts the main body case 3 to collect dust. The state which supports the bag holding member 20 is shown. In FIG. 7, the dust collection bag 21 housed in the dust collection chamber 16 is omitted for easy understanding of the entire configuration of the electric vacuum cleaner 1.

ここで、図7に示すように、集塵室16の幅Sは、電気掃除機1の全長Sの半分以上を占めており、大容量の集塵室16となっている。 Here, as shown in FIG. 7, the width S 2 of the dust collection chamber 16 occupies more than half of the total length S 1 of the electric vacuum cleaner 1, and the dust collection chamber 16 has a large capacity.

つまり、電気掃除機1の全長Sと集塵室16の幅Sとの関係はS>S/2であり、集塵室16の幅Sと電動送風機室の幅Sとの関係は、S>Sである。 In other words, the relationship between the width S 2 of the full-length S 1 and the dust collecting chamber 16 of the vacuum cleaner 1 is S 2> S 1/2, the width S 2 and the width S 3 of the electric blower chamber of the dust collection chamber 16 The relationship is S 2 >S 3 .

このように、本実施例における電気掃除機1は、電気掃除機1の本体の前面から後面に跨る横断面において、集塵室16の幅が電気掃除機1の本体の全長の半分以上の長さになるように設けられている。これにより、集塵室16を大容量化つまり電気掃除機1を大集塵化しても、電気掃除機自体をコンパクトに設計することができ、電気掃除機1の取り扱いが容易になる。   As described above, in the electric vacuum cleaner 1 according to the present embodiment, the width of the dust collecting chamber 16 is at least half the total length of the main body of the electric vacuum cleaner 1 in a cross section extending from the front surface to the rear surface of the main body of the electric vacuum cleaner 1. It is provided so that it becomes small. Thereby, even if the dust collection chamber 16 has a large capacity, that is, even if the electric vacuum cleaner 1 has a large amount of dust, the electric vacuum cleaner itself can be designed compact and the electric vacuum cleaner 1 can be easily handled.

電気掃除機の前面から後面に跨る横断面において、集塵室の幅が前記電気掃除機の全長の半分よりも長いことにより、集塵室の容量が大きい電気掃除機1とすることができる。幅が大きな集塵室に、その幅に合う大きさの集塵袋21を取り付ける際、特許文献1に記載の構造では、集塵袋21の袋部も大きく集塵室内に納めづらいため、取り付けが容易ではない恐れがある。実施例中に記載のように、集塵袋21が装着されていない状態においては、バネの力により上方へ付勢されて保持されている集塵袋保持部材20であれば、大きな集塵袋21の取り付けが容易となる。   In the cross section extending from the front surface to the rear surface of the electric vacuum cleaner, the width of the dust collecting chamber is longer than half the entire length of the electric vacuum cleaner, so that the electric vacuum cleaner 1 having a large capacity of the dust collecting chamber can be obtained. When the dust collecting bag 21 having a size matching the width is attached to the dust collecting chamber having a large width, in the structure described in Patent Document 1, the bag portion of the dust collecting bag 21 is also large and difficult to fit in the dust collecting chamber. May not be easy. As described in the embodiments, when the dust collecting bag 21 is not attached, the dust collecting bag holding member 20 that is biased and held upward by the force of the spring is a large dust collecting bag. It becomes easy to attach 21.

図8乃至図9を用いて、本実施例における電気掃除機1の集塵袋21および集塵袋保持部材20について詳細に説明する。   The dust collecting bag 21 and the dust collecting bag holding member 20 of the electric vacuum cleaner 1 according to the present embodiment will be described in detail with reference to FIGS. 8 to 9.

図9A乃至図9Cは、本実施例における集塵袋21を示している。図9Aは集塵袋21の平面図である。また、図9Bは、図9AにおけるA−A’断面を示している。図9Cは、図9AにおけるB−B’矢視図である。   9A to 9C show the dust collecting bag 21 in this embodiment. FIG. 9A is a plan view of the dust collecting bag 21. Further, FIG. 9B shows a cross section taken along line A-A′ in FIG. 9A. FIG. 9C is a view on arrow B-B′ in FIG. 9A.

図9A〜Cに示すように、集塵袋21は、口板部21aと、口板部21aに接続された袋部21bと、袋部21bにおける口板部21aとは反対側を塞ぐ塞ぎ部材22と、で構成されている。   As shown in FIGS. 9A to 9C, the dust collecting bag 21 includes a mouth plate portion 21a, a bag portion 21b connected to the mouth plate portion 21a, and a closing member that closes the side of the bag portion 21b opposite to the mouth plate portion 21a. 22 and 22.

図8は、集塵袋21の口板部21aを示している。口板部21aは、略四角板形状をしており、口板22の中央部には蓋4に設けられたホース接続口7と向かい合う開口23が設けられている。ホース接続口7から吸引された空気とゴミは、口板部21aの開口23を介して集塵袋21に吸い込まれる。   FIG. 8 shows the mouth plate portion 21 a of the dust collecting bag 21. The mouth plate 21a has a substantially rectangular plate shape, and an opening 23 facing the hose connection port 7 provided on the lid 4 is provided at the center of the mouth plate 22. The air and dust sucked from the hose connection port 7 are sucked into the dust collecting bag 21 through the opening 23 of the mouth plate portion 21a.

口板部21aの一側部には、切欠き24が設けられている。切欠き24は、前記のように、集塵袋21を集塵袋保持部材20に装着する際、集塵袋保持部材20に設けられた凸部(突起)27が入り、集塵袋保持部材20に対する口板部21aの位置決めとして機能する。   A cutout 24 is provided on one side of the mouth plate portion 21a. As described above, the notch 24 is provided with the convex portion (protrusion) 27 provided on the dust collecting bag holding member 20 when the dust collecting bag 21 is mounted on the dust collecting bag holding member 20, and the dust collecting bag holding member is provided. It functions as positioning of the mouth plate portion 21 a with respect to 20.

また、口板部21aには、切り欠き24の左右に位置するように穴25および穴26が設けられている。穴25,26は、切り欠き24よりも小さい開口である。前記のように、穴25、26は、集塵袋21を集塵袋保持部材20に装着する際、後述する集塵袋保持部材20に設けられた凸部(突起)28および29にそれぞれ嵌合し、集塵袋保持部材20に対する口板部21aの位置決めおよび係止手段として機能する。   Further, the mouth plate portion 21 a is provided with holes 25 and 26 so as to be located on the left and right of the cutout 24. The holes 25 and 26 are openings smaller than the cutout 24. As described above, when the dust bag 21 is mounted on the dust bag holding member 20, the holes 25 and 26 are fitted into the convex portions (projections) 28 and 29 provided on the dust bag holding member 20, which will be described later, respectively. Together, they function as positioning and locking means for the mouth plate 21a with respect to the dust bag holding member 20.

なお、本実施例においては、口板部21aに設けられる穴25および26、集塵袋保持部材20に設けられる凸部(突起)28および29は、それぞれ2つずつ設けられている例を示しているが、各々少なくとも1つ以上設けてあれば、口板部21aを集塵袋保持部材20に保持(係止)するという効果を奏する。但し、口板部21aの穴、集塵袋保持部材20の凸部(突起)をそれぞれ2つ以上設けることにより、集塵袋保持部材20に対する口板部21aの装着の位置決めの精度を向上することができる。   In addition, in this embodiment, the holes 25 and 26 provided in the mouth plate portion 21a and the convex portions (projections) 28 and 29 provided in the dust collecting bag holding member 20 are provided two by two, respectively. However, if at least one is provided for each, the effect of holding (locking) the mouth plate portion 21a on the dust collecting bag holding member 20 is obtained. However, by providing two or more holes in the mouth plate portion 21a and two or more protrusions (projections) of the dust collecting bag holding member 20, the accuracy of positioning the mouth plate portion 21a with respect to the dust collecting bag holding member 20 is improved. be able to.

口板部21aの素材としては、例えば、プラスチックや厚紙などを用いることができる。   As the material of the mouth plate portion 21a, for example, plastic or cardboard can be used.

袋部21bは袋開口部21b1と端開放部21b2とを有する袋状の部分である。袋開口部21b1は、口板部21aの開口23とつながっている。端開放部21b2は、袋開口部21b1とは反対の方にあり、塞ぎ部材22で塞ぐことができる。   The bag portion 21b is a bag-shaped portion having a bag opening portion 21b1 and an open end portion 21b2. The bag opening 21b1 is connected to the opening 23 of the mouth plate 21a. The open end 21b2 is located on the opposite side of the bag opening 21b1 and can be closed by the closing member 22.

集塵袋21の袋部21bの素材としては、例えば、繊維や不織布を用いることができる。この場合、集塵袋21内のゴミを廃棄した後に洗浄して繰り返し使用することができる。   As the material of the bag portion 21b of the dust collecting bag 21, for example, fiber or non-woven fabric can be used. In this case, the dust in the dust bag 21 can be discarded and then washed and repeatedly used.

また、集塵袋21を使い捨てする場合は、紙やメルトブローなどのプラスチック素材を用いて、いわゆる紙パックとしてもよい。   Further, when the dust bag 21 is disposable, a so-called paper pack may be formed by using a plastic material such as paper or melt blown.

なお、集塵袋21の袋部21bには、集塵室16内へ装着される際に、集塵室16の内壁やその他の構造物と干渉しないよう、肩落ち部36が設けられている。肩落ち部36は、袋部21bにおける橋開放部21b2とは反対側の端部で口板部21aの左右に設けられている。集塵袋21において、袋部21bの反対側の端部は、口板部21aの切り欠き24がある端部とは反対側の端部よりも切り欠き24側に位置している。   The bag portion 21b of the dust collecting bag 21 is provided with a shoulder drop portion 36 so as not to interfere with the inner wall of the dust collecting chamber 16 and other structures when it is mounted in the dust collecting chamber 16. . The shoulder drop portions 36 are provided on the left and right sides of the mouth plate portion 21a at the ends of the bag portion 21b opposite to the bridge opening portion 21b2. In the dust collecting bag 21, the end portion on the opposite side of the bag portion 21b is located closer to the cutout 24 than the end portion on the opposite side of the end portion having the cutout 24 of the mouth plate portion 21a.

袋部21bは、口板部21a側から離れる方向に行くに従い口板部21aの反対側の端部から離れる方向に向かうような形状をしており、肩落ち部36は、その斜め形状の部分を指す。集塵袋21を集塵袋取り付け部22に取り付けた際、口板部21aの切り欠き24がある端部が電気掃除機1の後ろ方向、反対側の端部が電気掃除機1の前方向を向くように位置している。   The bag portion 21b is shaped so as to move away from the end on the opposite side of the mouth plate portion 21a as it goes away from the mouth plate portion 21a side, and the shoulder drop portion 36 has a diagonal portion. Refers to. When the dust bag 21 is attached to the dust bag attaching portion 22, the end portion of the mouth plate portion 21a where the cutout 24 is present is the rearward direction of the electric vacuum cleaner 1, and the opposite end is the frontward direction of the electric vacuum cleaner 1. It is located to face.

袋部21bが平面視で略四角形状であると、集塵袋21を集塵袋保持部材20に装着することで集塵袋保持部材20が下方向に回動しても、袋部21bの角が本体ケース3に接触してしまい下方向へ回動しきらないという恐れがある。更に、袋部21bの角が本体ケース3に接触し、蓋4が閉まらなくなる恐れがある。この場合、袋部21bを集塵室16内に手で入れ直すという手間がかかる恐れがある。   When the bag portion 21b has a substantially quadrangular shape in a plan view, even if the dust bag 21 is attached to the dust bag holding member 20 and the dust bag holding member 20 rotates downward, There is a risk that the corners may come into contact with the body case 3 and may not rotate downward completely. Furthermore, the corners of the bag portion 21b may come into contact with the main body case 3 and the lid 4 may not close. In this case, it may take time and effort to re-insert the bag portion 21b into the dust collecting chamber 16.

本実施形態のように、袋部21bに肩落ち部36を設けることで、袋部21bが本体ケース3に接触する恐れを低減することができる。これにより、集塵袋21を集塵袋保持部材20に取り付けるだけで、集塵袋保持部材20が下方向に回動し、集塵袋21の本体接触部20dと本体ケース3とが接触することができ、容易に装着することができるという効果を奏する。   By providing the shoulder drop portion 36 on the bag portion 21b as in the present embodiment, it is possible to reduce the risk of the bag portion 21b coming into contact with the main body case 3. Thereby, only by attaching the dust collecting bag 21 to the dust collecting bag holding member 20, the dust collecting bag holding member 20 rotates downward, and the main body contact portion 20d of the dust collecting bag 21 and the main body case 3 come into contact with each other. Therefore, there is an effect that it can be easily mounted.

図10A乃至図10Dを用いて、集塵袋21の口板部21aを集塵袋保持部材20に装着する方法を説明する。図10A乃至図10Dは、集塵袋保持部材20および口板部21aの一部断面を示している。   A method of mounting the mouth plate portion 21a of the dust collecting bag 21 on the dust collecting bag holding member 20 will be described with reference to FIGS. 10A to 10D. 10A to 10D show partial cross sections of the dust collecting bag holding member 20 and the mouth plate portion 21a.

先ず、図10Aのように、集塵袋21の口板部21aを集塵袋保持部材20の保持部20bに対してほぼ平行な状態となるように近づける。   First, as shown in FIG. 10A, the mouth plate portion 21a of the dust collecting bag 21 is brought close to the holding portion 20b of the dust collecting bag holding member 20 so as to be substantially parallel thereto.

次に、図10Bに示すように、口板部21aを、集塵袋保持部材20に設けられたガイドレール30上におき、ガイドレール30上を滑らせるように押す。   Next, as shown in FIG. 10B, the mouth plate 21a is placed on the guide rail 30 provided on the dust collecting bag holding member 20, and is pushed so as to slide on the guide rail 30.

次に、図10Cに示すように、口板部21aを、集塵袋保持部材20に設けられた傾斜部35に沿うように、押す。   Next, as shown in FIG. 10C, the mouth plate portion 21a is pushed along the inclined portion 35 provided on the dust bag holding member 20.

更に口板部21aを押すことで、図10Dに示すように、口板部21aは集塵袋保持部材20に設けられた凸部(突起)28および29を乗り越え、凸部(突起)28,29と口板部21aの穴25,26が合う位置で嵌合し、口板部21aが集塵袋保持部材20上に装着される。集塵袋21が集塵袋保持部材20にロックされて保持される。   By further pushing the mouth plate portion 21a, as shown in FIG. 10D, the mouth plate portion 21a gets over the convex portions (projections) 28 and 29 provided on the dust collecting bag holding member 20, and the convex portion (projection) 28, 29 and the holes 25 and 26 of the mouth plate portion 21a are fitted to each other, and the mouth plate portion 21a is mounted on the dust collecting bag holding member 20. The dust bag 21 is locked and held by the dust bag holding member 20.

このとき、集塵袋保持部材20の凸部(突起)27および口板部21aの切欠き24は、集塵袋保持部材20上における口板部21aの位置決めとして機能している。   At this time, the convex portion (projection) 27 of the dust bag holding member 20 and the notch 24 of the mouth plate portion 21 a function as positioning of the mouth plate portion 21 a on the dust bag holding member 20.

図11A乃至図11Cを用いて、集塵袋保持部材20に設けられた凸部(突起)28および傾斜部35、段差部135,235、ガイドレール30,1301,230について説明する。図11A乃至図11Cは、いずれも図4におけるC−C’断面を示している。   With reference to FIGS. 11A to 11C, the convex portion (projection) 28 and the inclined portion 35, the step portions 135 and 235, and the guide rails 30, 1301 and 230 provided on the dust collecting bag holding member 20 will be described. 11A to 11C each show a C-C′ cross section in FIG. 4.

図11Aは、本実施形態の図である。図11Aに示す集塵袋保持部材20には、傾斜したガイドレール30と、ガイドレール30に連続して設けられている傾斜部35と、が設けられている。   FIG. 11A is a diagram of this embodiment. The dust collecting bag holding member 20 shown in FIG. 11A is provided with an inclined guide rail 30 and an inclined portion 35 provided continuously to the guide rail 30.

このタイプの集塵袋保持部材20に口板部21aを装着する場合、口板部21aをガイドレール30と傾斜部35の傾斜に沿って押すことで、口板部21aの先端部分が比較的容易に凸部(突起)28を乗り越え、凸部(突起)28に穴25を嵌合させることができるという効果を奏する。   When the mouth plate portion 21a is attached to the dust collecting bag holding member 20 of this type, by pushing the mouth plate portion 21a along the inclination of the guide rail 30 and the inclined portion 35, the tip portion of the mouth plate portion 21a is relatively moved. There is an effect that the convex portion (projection) 28 can be easily overcome and the hole 25 can be fitted into the convex portion (projection) 28.

但し、傾斜が設けられている分、図11Bの集塵袋保持部材20に比べて、穴25を凸部(突起)28に係止し難くなるため、集塵袋保持部材20を形成する際に傾斜部35の傾斜角度に注意が必要になる。   However, since the slope is provided, it becomes more difficult to lock the hole 25 to the convex portion (projection) 28 as compared with the dust collecting bag holding member 20 of FIG. 11B. Attention must be paid to the inclination angle of the inclined portion 35.

図11Bは、図11Aの別実施例であり、集塵袋保持部材20には、平坦なガイドレール130と、ガイドレール130と段差となるように設けられた段差部135と、を設けた例を示している。このタイプの集塵袋保持部材20に口板部21aを装着する場合、口板部21aをガイドレール130に沿って押し、口板部21aの先端部分を少し持ち上げながら段差部135を乗り越え、凸部(突起)28に穴25を嵌合させる。   FIG. 11B is another example of FIG. 11A, and an example in which the dust bag holding member 20 is provided with a flat guide rail 130 and a step portion 135 provided so as to form a step with the guide rail 130. Is shown. When the mouth plate portion 21a is attached to the dust collecting bag holding member 20 of this type, the mouth plate portion 21a is pushed along the guide rails 130, and the tip portion of the mouth plate portion 21a is slightly lifted to get over the step portion 135 to project. The hole 25 is fitted into the portion (projection) 28.

このタイプの集塵袋保持部材20は、集塵袋21を装着する際に口板部21aの先端部分を少し持ち上げる必要があるが、ガイドレール130の表面は凸部(突起)28が設けられている集塵袋保持部材20の表面とほぼ平行になっており、比較的簡易に集塵袋保持部材20にガイドレール30を形成することができるという効果を奏する。   In this type of dust collecting bag holding member 20, the tip portion of the mouth plate portion 21a needs to be slightly lifted when the dust collecting bag 21 is mounted, but the surface of the guide rail 130 is provided with a convex portion (projection) 28. Since it is substantially parallel to the surface of the dust collecting bag holding member 20, the guide rail 30 can be formed on the dust collecting bag holding member 20 relatively easily.

図11Cは、図11Aに示した集塵袋保持部材20の変形例である。図11Cに示す集塵袋保持部材20には、傾斜角θで傾斜したガイドレール230と、ガイドレール230とは異なる傾斜角θで傾斜した傾斜部235と、が設けられている。 FIG. 11C is a modification of the dust bag holding member 20 shown in FIG. 11A. The dust collecting bag holding member 20 shown in FIG. 11C is provided with a guide rail 230 inclined at an inclination angle θ 2 and an inclined portion 235 inclined at an inclination angle θ 1 different from the guide rail 230.

このタイプの集塵袋保持部材20は、図11Aに示した集塵袋保持部材20と同様にガイドレール230と傾斜部235とに傾斜が設けられており、口板部21aを傾斜部235の傾斜に沿って挿入することで、口板部21aの先端部分が比較的容易に凸部(突起)28を乗り越え、凸部(突起)28に穴25を嵌合させることができる。   In this type of dust collecting bag holding member 20, the guide rail 230 and the inclined portion 235 are provided with inclination similarly to the dust collecting bag holding member 20 shown in FIG. By inserting along the inclination, the tip portion of the mouth plate portion 21a can relatively easily pass over the convex portion (projection) 28, and the hole 25 can be fitted into the convex portion (projection) 28.

ここで、傾斜部235の傾斜角θがガイドレール230の傾斜角θよりも傾斜しているため、穴25を凸部(突起)28に係止し易くなるという効果を奏する。 Here, since the inclination angle θ 1 of the inclined portion 235 is larger than the inclination angle θ 2 of the guide rail 230, the hole 25 can be easily locked to the convex portion (projection) 28.

集塵袋保持部材20が略コの字型であって、ガイドレールは、略コの字型の両側にあるため、集塵袋21の口板22の両側を支持するよう載置することができる。また、ガイドレール30が略コの字型の両側にあるため、集塵袋21の口板22の両側を支持したままガイドレール30に沿って凸部(突起)28および凸部(突起)29の方へとスライドさせることができる。スライドさせることができるため、集塵袋21と集塵袋保持部材20に取り付け易いという効果を奏する。   Since the dust collecting bag holding member 20 is substantially U-shaped and the guide rails are on both sides of the substantially U-shaped, the dust collecting bag 21 can be placed so as to support both sides of the mouth plate 22. it can. Further, since the guide rails 30 are on both sides of the substantially U-shape, the convex portions (protrusions) 28 and the convex portions (protrusions) 29 are provided along the guide rails 30 while supporting both sides of the mouth plate 22 of the dust collecting bag 21. Can be slid towards. Since it can be slid, the dust bag 21 and the dust bag holding member 20 can be easily attached.

図12は本発明の実施の形態の一例に係る塵落とし部材19の斜視図である。   FIG. 12 is a perspective view of the dust removing member 19 according to an example of the embodiment of the present invention.

塵落とし部材19は、ハニカム構造で形成された、通気穴37を有している。通気穴37を設けていることにより、通気性を持たせることができる。各通気穴37がハニカム構造となるように塵落とし部材19を形成しているため、強度を確保するためのリブなどを設けることなく十分な強度を確保することができ、かつリブなどを設けることがないため小型、軽量とすることができる。   The dust removing member 19 has a ventilation hole 37 formed of a honeycomb structure. By providing the ventilation hole 37, it is possible to provide ventilation. Since the dust removing member 19 is formed so that each ventilation hole 37 has a honeycomb structure, it is possible to secure sufficient strength without providing a rib or the like for securing the strength, and to provide the rib or the like. It is possible to make it compact and lightweight because there is no

図13は本発明の実施の形態の一例に係る電気掃除機本体の集塵袋21と塵落とし部材19の横断面図である。   FIG. 13 is a transverse cross-sectional view of the dust collecting bag 21 and the dust removing member 19 of the electric vacuum cleaner body according to the example of the embodiment of the present invention.

図13のような状態のとき、塵落とし部材19は蓋4の内側に取り付けられ、塵落とし部材19のリブ39が蓋体4に当接することによって、塵落とし部材19と蓋体4の間には流路空間38が形成されている。これにより、集塵袋21が膨らんだ際も、集塵袋21を通過した空気が流路空間38を通ることで、集塵袋21が蓋体4の内側に張り付くことなく空気の流れる空間を確保し、集塵袋21に塵埃が堆積した場合も吸引力の低下を防ぐことができる。   In the state as shown in FIG. 13, the dust removing member 19 is attached to the inside of the lid 4, and the rib 39 of the dust removing member 19 abuts on the lid 4 so that the dust removing member 19 and the lid 4 are separated from each other. A channel space 38 is formed. As a result, even when the dust collecting bag 21 is inflated, the air that has passed through the dust collecting bag 21 passes through the flow path space 38, so that the dust collecting bag 21 does not stick to the inside of the lid body 4 and the air flowing space is maintained. Even if dust is accumulated in the dust collecting bag 21, it is possible to prevent the suction force from decreasing.

図14、15は本発明の実施の形態の一例に係る電気掃除機の集塵袋21と塵落とし部材19の断面図である。   14 and 15 are cross-sectional views of the dust collecting bag 21 and the dust removing member 19 of the electric vacuum cleaner according to the example of the embodiment of the present invention.

図14に示すように塵落とし部材19は上下に動作可能な状態で、蓋4に取り付けられ、初期状態においては水平に配置され、弾性体により前記集塵袋21から離れる方向に力を加えられている。この状態から電動或いは電源コードの巻き取り機構を動作した際に、塵落とし部材19が回動軸43を中心に集塵袋21の位置する下方向に動作する(図15)。塵落とし部材19が下がることで集塵袋21を叩き、集塵袋の内部表面に堆積した塵埃42を落とし、吸込力を回復する。塵落とし部材19は弾性変形を利用し、塵落とし部材19が下側に可動しても再び元の水平な配置の位置に戻ることができる。このとき、落とし部材19の回転軸から最も離れた位置の形状が凸部(突起)40である。   As shown in FIG. 14, the dust removing member 19 is vertically movable and is attached to the lid 4, and is horizontally arranged in the initial state, and a force is applied by the elastic body in a direction away from the dust collecting bag 21. ing. When the electric or power cord winding mechanism is operated from this state, the dust removing member 19 moves downward with the dust collecting bag 21 positioned around the rotation shaft 43 (FIG. 15). When the dust removing member 19 is lowered, the dust collecting bag 21 is hit, the dust 42 accumulated on the inner surface of the dust collecting bag is dropped, and the suction force is restored. The dust removing member 19 uses elastic deformation and can return to the original horizontal position even if the dust removing member 19 moves downward. At this time, the shape of the dropping member 19 at the position farthest from the rotation axis is the convex portion (projection) 40.

次に、塵落とし部材19における凸部(突起)40の位置関係について、説明する。   Next, the positional relationship of the protrusions (projections) 40 of the dust removing member 19 will be described.

図16は本発明の実施の形態の一例に係る電気掃除機の蓋4と塵落とし部材19の横断面図である。   FIG. 16 is a cross-sectional view of the lid 4 and the dust removing member 19 of the electric vacuum cleaner according to the example of the embodiment of the present invention.

塵落とし部材19は蓋体4に沿うような曲面41を有し、曲面41から集塵袋21の側に最も突出した部位が凸部(突起)40である。塵落とし部材19を支持する軸部から最も遠い位置に配置されている。これにより、塵落とし部材が上下に動作した時に、最も効果的に集塵袋21を叩くことが出来、より長く吸引力の低下を防ぐことができる。   The dust removing member 19 has a curved surface 41 that extends along the lid body 4, and the most protruding portion (projection) 40 from the curved surface 41 toward the dust collecting bag 21 side. It is arranged at a position farthest from the shaft portion that supports the dust removing member 19. As a result, when the dust removing member moves up and down, the dust collecting bag 21 can be hit most effectively, and a decrease in suction force can be prevented for a long time.

塵落とし部材19により集塵袋21の内部表面の塵を除去している様子は、蓋4に設けられた窓9を介して電気掃除機1の外側から目視で確認することができる。   The state of removing dust on the inner surface of the dust collecting bag 21 by the dust removing member 19 can be visually confirmed from the outside of the electric vacuum cleaner 1 through the window 9 provided in the lid 4.

ここで、塵落とし部材19は、集塵袋保持部材20と直接干渉しないような形状にすることで、集塵袋21のみを振動させることができ、より効率的に集塵袋21の内部表面に付着した塵を叩き落とすことができる。なお、集塵袋保持部材20の形状を塵落とし部材19と直接干渉しないような形状に形成してもよい。   Here, since the dust removing member 19 has a shape that does not directly interfere with the dust collecting bag holding member 20, only the dust collecting bag 21 can be vibrated, and the inner surface of the dust collecting bag 21 can be more efficiently. Dust adhering to can be knocked off. The dust bag holding member 20 may be shaped so as not to directly interfere with the dust removing member 19.

本実施形態では、平面視で、塵落とし部材19は略凹形状であり、集塵袋保持部材20は略Y字形状である。塵落とし部材19の略凹形状の左右の凸部分が、集塵袋保持部材20の略Y字形状の脇の部分に位置することになる。そのため、塵落とし部材19と集塵袋保持部材20とは直接干渉することがなく、塵落とし部材19により集塵袋21のみを振動させることができる。   In the present embodiment, the dust removing member 19 has a substantially concave shape and the dust collecting bag holding member 20 has a substantially Y shape in a plan view. The left and right convex portions having a substantially concave shape of the dust removing member 19 are located at the side portions of the dust collecting bag holding member 20 having a substantially Y shape. Therefore, the dust removing member 19 and the dust collecting bag holding member 20 do not directly interfere with each other, and only the dust collecting bag 21 can be vibrated by the dust removing member 19.

上記の通り、塵落とし部材19により、集塵袋21の内部表面に付着した塵を除去することができる。集塵袋21の内部表面に付着した塵埃を除去することで集塵袋21の目詰まりを防ぎ、集塵袋21に多くの塵埃を集めることができる。なお、目詰まりを防ぐため、電気掃除機の吸引持続率を高くすることができる。   As described above, the dust removing member 19 can remove dust adhering to the inner surface of the dust collecting bag 21. By removing the dust adhering to the inner surface of the dust collecting bag 21, clogging of the dust collecting bag 21 can be prevented and a large amount of dust can be collected in the dust collecting bag 21. In addition, in order to prevent clogging, the suction duration of the electric vacuum cleaner can be increased.

以上説明したように、本実施例における電気掃除機によれば、掃除機本体への集塵袋21の装着が容易な集塵袋式の電気掃除機を実現することができる。   As described above, according to the electric vacuum cleaner of the present embodiment, it is possible to realize a dust bag electric vacuum cleaner in which the dust bag 21 can be easily attached to the cleaner body.

また、集塵袋21の内側表面に付着した塵を落とす塵落とし機構を集塵室内に設けることにより、集塵袋21の目詰まりを抑制し、吸引力が低下し難い集塵袋式の電気掃除機を実現することができる。   Further, by providing a dust removing mechanism for dropping the dust adhering to the inner surface of the dust collecting bag 21 in the dust collecting chamber, clogging of the dust collecting bag 21 is suppressed, and the suction force is less likely to decrease. A vacuum cleaner can be realized.

また、電気掃除機の前面から後面に跨る横断面において、集塵室の幅を掃除機本体の全長の半分よりも長くなるように集塵室を設けることで、集塵能力を大容量化しつつ、電気掃除機自体をコンパクトに設計することが可能になる。   Also, in the cross-section that extends from the front surface to the rear surface of the vacuum cleaner, the dust collection chamber is provided so that the width of the dust collection chamber is longer than half the entire length of the cleaner body, thereby increasing the dust collection capacity. The vacuum cleaner itself can be designed compactly.
