集塵装置30の駆動装置20への装着時において、係合凸部52は、係合凹部51の幅の広い部分に挿入され、駆動装置20に対して集塵装置30を装着方向(後方)へスライドさせることにより、係合凸部52が係合凹部51の厚肉部51a側へスライドして係合する。また、係合凸部52には、集塵装置30を装着方向にスライドした際に、係合凹部52の切り込み部51bに差し込まれる差込リブ52aが設けられている。
As shown in FIGS. 4, 7 and 8, the engaging convex portion 52 of the engaging mechanism M2 provided in the dust collecting container 31 is engaged with the engaging mechanism M2 provided in the pipe portion 21d of the drive device 20. It is formed in a hook shape protruding toward the second lock mechanism M3 side (front in the mounting direction) so that it can be inserted into the joint recess 51.
When the dust collector 30 is mounted on the drive device 20, the engaging convex portion 52 is inserted into the wide portion of the engaging recess 51, and the dust collector 30 is mounted in the mounting direction (rear) with respect to the drive device 20. By sliding to, the engaging convex portion 52 slides toward the thick portion 51a side of the engaging concave portion 51 and engages with the engaging concave portion 51. Further, the engaging convex portion 52 is provided with an insertion rib 52a that is inserted into the notch portion 51b of the engaging concave portion 52 when the dust collector 30 is slid in the mounting direction.

また、図4と図7に示すように、集塵容器31において、周壁部31bの外周面と底部31aとの間であって、係合凸部52の近傍位置には凹部31cが設けられている。この凹部31cは、周壁部31bと底部31aとの間の丸角部を内側へ凹ませることにより形成されている。なお、凹部31cの内側は、集塵容器31内で旋回する塵埃の旋回止めとなる凸部31dとなっている。 Further, as shown in FIGS. 4 and 7, in the dust collecting container 31, a concave portion 31c is provided between the outer peripheral surface of the peripheral wall portion 31b and the bottom portion 31a and in the vicinity of the engaging convex portion 52. There is. The recess 31c is formed by recessing the rounded corner portion between the peripheral wall portion 31b and the bottom portion 31a inward. The inside of the recess 31c is a convex portion 31d that prevents the dust swirling in the dust collecting container 31.

<駆動装置に対する集塵装置の着脱について>
図7および図8に示すように、集塵装置30を駆動装置20の集塵装置装着部21gに装着する際、まず、集塵装置30の外周面を集塵装置装着部21gのパイプ部21d(第2当接部)に当接する。
このとき、集塵装置30の第2のロック機構M3および係合凸部52がパイプ部21d側に向けられることによって適正に装着が行われることを使用者は認識することができる。またこのとき、集塵装置30の凹部31cを駆動装置20の当接凸部21dfに位置させることにより、集塵装置30側の係合機構M2の係合凸部52が、駆動装置20側の係合機構M2の係合凹部51の幅の広い部分に挿入される。またこれにより、集塵装置30のフィルタ部32と駆動装置20の電動送風機収納部21aの空気導入口21aa(第1当接部)との間に、スライド前の適正な隙間が形成される。
<About attachment / detachment of dust collector to drive device>
As shown in FIGS. 7 and 8, when the dust collector 30 is mounted on the dust collector mounting portion 21g of the drive device 20, first, the outer peripheral surface of the dust collector 30 is mounted on the pipe portion 21d of the dust collector mounting portion 21g. Contact (second contact portion).
At this time, the user can recognize that the second lock mechanism M3 and the engaging convex portion 52 of the dust collector 30 are directed toward the pipe portion 21d so that the dust collecting device 30 is properly mounted. At this time, by locating the concave portion 31c of the dust collecting device 30 at the contact convex portion 21df of the driving device 20, the engaging convex portion 52 of the engaging mechanism M2 on the dust collecting device 30 side is moved to the driving device 20 side. It is inserted into the wide portion of the engaging recess 51 of the engaging mechanism M2. As a result, an appropriate gap before sliding is formed between the filter portion 32 of the dust collector 30 and the air introduction port 21aa (first contact portion) of the electric blower storage portion 21a of the drive device 20.

次に、集塵装置30を駆動装置20に対して電動送風機収納部21a側の装着方向へスライドさせる。このとき、集塵装置30側の第1のロック機構M1の係止爪42bが、駆動装置20側の第1のロック機構M1の係止凸部41に係止する。また、集塵装置30側の係合凸部52が駆動装置20側の係合凹部51の厚肉部51aと接触した状態、すなわち、係合凸部52と集塵容器31の外周面との間に係合凹部51の厚肉部51aがスライドして挟まれた状態となり、係合凸部52と係合凹部51とが係合する。これにより、集塵装置30の駆動装置20への装着が完了する。なお、厚肉部51aを設けることにより、集塵装置30が駆動装置20に対して離接する方向(上下方向)へのがたつきが低減される。 Next, the dust collector 30 is slid with respect to the drive device 20 in the mounting direction on the side of the electric blower storage unit 21a. At this time, the locking claw 42b of the first locking mechanism M1 on the dust collector 30 side is locked to the locking convex portion 41 of the first locking mechanism M1 on the driving device 20 side. Further, a state in which the engaging convex portion 52 on the dust collecting device 30 side is in contact with the thick portion 51a of the engaging concave portion 51 on the driving device 20 side, that is, the engaging convex portion 52 and the outer peripheral surface of the dust collecting container 31 are in contact with each other. The thick portion 51a of the engaging recess 51 slides and is sandwiched between them, and the engaging convex portion 52 and the engaging recess 51 engage with each other. This completes the mounting of the dust collector 30 on the drive device 20. By providing the thick portion 51a, rattling in the direction in which the dust collector 30 separates from the drive device 20 (vertical direction) is reduced.

また、集塵装置30の装着時においては、集塵装置30の第2のロック機構M3が、駆動装置20のパイプ部21dの下端に設けられた収納凹部21de内に収納される。
さらに、集塵装置30のスライドによって、集塵装置30の流入口31baの接続面が、駆動装置20の流出口21dcに設けられたパッキン21ddの接続面に接近して密着する。このとき、流入口31baの接続面および流出口21dcの接続面は互いに平行であり、かつ、装着方向に対しては互いに傾斜しているため、流入口31baの接続面とパッキン21ddの接続面との摺動面積が小さくなり、流入口31baがパッキン21ddに擦れることによるパッキン21ddの損傷が低減する。
また、集塵装置30のスライドによって、集塵装置30のフィルタ部32の端部の排出口が、駆動装置20の空気導入口21aaのパッキン21ac(図6参照)に当接する。
When the dust collector 30 is attached, the second lock mechanism M3 of the dust collector 30 is housed in the storage recess 21de provided at the lower end of the pipe portion 21d of the drive device 20.
Further, by sliding the dust collector 30, the connection surface of the inflow port 31ba of the dust collector 30 approaches and adheres to the connection surface of the packing 21dd provided at the outlet 21dc of the drive device 20. At this time, since the connection surface of the inflow port 31ba and the connection surface of the outflow port 21dc are parallel to each other and inclined with respect to the mounting direction, the connection surface of the inflow port 31ba and the connection surface of the packing 21dc The sliding area of the packing 21dd is reduced, and the damage to the packing 21dd due to the inflow port 31ba rubbing against the packing 21dd is reduced.
Further, by sliding the dust collector 30, the discharge port at the end of the filter unit 32 of the dust collector 30 comes into contact with the packing 21ac (see FIG. 6) of the air introduction port 21aa of the drive device 20.

次に、集塵装置30の駆動装置20からの取り外しについて説明する。
図9は第1実施形態の電気掃除機における駆動装置から集塵装置を右手で取り外すときの状態を説明する図であり、図10は第1実施形態の電気掃除機における駆動装置から集塵装置を左手で取り外すときの状態を説明する図である。また、図11は第1実施形態の電気掃除機における駆動装置から集塵装置を右手で取り外すときの状態を説明する別の図であり、図12は第1実施形態の電気掃除機における駆動装置から集塵装置を左手で取り外すときの状態を説明する別の図である。
Next, the removal of the dust collector 30 from the drive device 20 will be described.
FIG. 9 is a diagram illustrating a state when the dust collector is removed from the drive device of the vacuum cleaner of the first embodiment with the right hand, and FIG. 10 is a diagram showing a state of removing the dust collector from the drive device of the vacuum cleaner of the first embodiment. It is a figure explaining the state when removing with a left hand. Further, FIG. 11 is another diagram for explaining a state when the dust collector is removed from the drive device in the vacuum cleaner of the first embodiment by a right hand, and FIG. 12 is another view for explaining a state when the dust collector is removed from the drive device in the vacuum cleaner of the first embodiment. It is another figure explaining the state when the dust collector is removed by the left hand.

この掃除機本体10によれば、図2、図9および図10に示すように、使用者は左右のどちらの手を使っても駆動装置20を集塵装置30から容易に取り外すことができる。
例えば、図2と図9に示すように、右手RHの親指で第1のロック機構M1のクランプボタン42aを押しながら集塵装置30を掴むことにより、第1のロック機構M1の係止爪42bが係止凸部41から離脱し、この状態で集塵装置30を装着方向とは逆方向(矢印A1方向、本実施の形態では前方)に、係合凸部52が係合凹部51の幅の広い部分に達するまでスライドさせる。その後、集塵装置30をパイプ部21dから離れる方向(下方)に移動させると、係合機構M2の係合凸部52が係合凹部51から離脱する(図7、図8参照)。あるいは、集塵装置30の凹部31cが駆動装置20の当接凸部21dfに当接することにより、駆動装置20のパイプ部21dに平行(矢印A1方向)に移動していた集塵装置30がパイプ部21dから離れる方向(矢印A2方向)に誘導され、係合機構M2の係合凸部52が係合凹部51から離脱する。これらにより、集塵装置30が駆動装置20から取り外される。なお、図示しない左手は、例えば、駆動装置20のハンドル21bを支持している。
According to the vacuum cleaner main body 10, as shown in FIGS. 2, 9 and 10, the user can easily remove the drive device 20 from the dust collector 30 by using either the left or right hand.
For example, as shown in FIGS. 2 and 9, by grasping the dust collector 30 while pressing the clamp button 42a of the first locking mechanism M1 with the thumb of the right hand RH, the locking claw 42b of the first locking mechanism M1 In this state, the dust collector 30 is disengaged from the locking convex portion 41, and the engaging convex portion 52 is the width of the engaging concave portion 51 in the direction opposite to the mounting direction (arrow A1 direction, forward in the present embodiment). Slide until you reach the wide area of. After that, when the dust collector 30 is moved in the direction away from the pipe portion 21d (downward), the engaging convex portion 52 of the engaging mechanism M2 is disengaged from the engaging concave portion 51 (see FIGS. 7 and 8). Alternatively, when the concave portion 31c of the dust collector 30 abuts on the contact convex portion 21df of the drive device 20, the dust collector 30 that has moved parallel to the pipe portion 21d of the drive device 20 (in the direction of arrow A1) is piped. Guided in a direction away from the portion 21d (direction of arrow A2), the engaging convex portion 52 of the engaging mechanism M2 is disengaged from the engaging concave portion 51. As a result, the dust collector 30 is removed from the drive device 20. The left hand (not shown) supports, for example, the handle 21b of the drive device 20.

また、図10に示すように、左手LHで集塵装置30を掴み、親指で第1のロック機構M1のクランプボタン42aを押しながら集塵装置30を装着方向とは逆方向(矢印A1方向)にスライドさせても、前記と同様に集塵装置30を駆動装置20から取り外すことができる。あるいは、小指で第1のロック機構M1のクランプボタン42aを押せるように左手LHで集塵装置30を掴み、小指でクランプボタン42aを押しながら集塵装置30を装着方向とは逆方向(矢印A1方向)にスライドさせても、同様に集塵装置30を駆動装置20から取り外すことができる。
あるいは、手の大きい使用者であれば、図11のように駆動装置20のパイプ部21dの上から(パイプ部21dを跨ぐように)右手RHで集塵装置30を掴み、親指でクランプボタン42aを押しながら集塵装置30を装着方向とは逆方向(矢印A1方向)にスライドさせても、前記と同様に集塵装置30を駆動装置20から取り外すことができる。また、図12のようにパイプ部21dの上から(パイプ部21dを跨ぐように)左手LHで集塵装置30を掴み、人差し指でクランプボタン42aを押しながら集塵装置30を装着方向とは逆方向(矢印A1方向)にスライドさせても、前記と同様に集塵装置30を駆動装置20から取り外すことができる。
Further, as shown in FIG. 10, the dust collector 30 is grasped by the left hand LH, and the dust collector 30 is mounted in the direction opposite to the mounting direction (arrow A1 direction) while pressing the clamp button 42a of the first lock mechanism M1 with the thumb. The dust collector 30 can be removed from the drive device 20 in the same manner as described above. Alternatively, the dust collector 30 is grasped by the left hand LH so that the clamp button 42a of the first lock mechanism M1 can be pressed with the little finger, and the dust collector 30 is mounted in the direction opposite to the mounting direction while pressing the clamp button 42a with the little finger (arrow A1). The dust collector 30 can also be removed from the drive device 20 by sliding it in the direction).
Alternatively, if the user has a large hand, as shown in FIG. 11, the dust collector 30 is grasped by the right hand RH from above the pipe portion 21d of the drive device 20 (so as to straddle the pipe portion 21d), and the clamp button 42a is used with the thumb. The dust collector 30 can be removed from the drive device 20 in the same manner as described above by sliding the dust collector 30 in the direction opposite to the mounting direction (arrow A1 direction) while pressing. Further, as shown in FIG. 12, the dust collector 30 is grasped from above the pipe portion 21d (straddling the pipe portion 21d) with the left hand LH, and the dust collector 30 is mounted in the opposite direction to the mounting direction while pressing the clamp button 42a with the index finger. The dust collector 30 can be removed from the drive device 20 in the same manner as described above by sliding in the direction (arrow A1 direction).

このように、掃除機本体10によれば、集塵装置30の駆動装置20への装着する際に、集塵装置30の駆動装置20への位置決め(スライド前の位置合わせ)が容易であり、装着性が向上している。
また、集塵装置30が駆動装置20に装着された状態において、第2のロック機構M3が、流入口31baと同様に駆動装置20のパイプ部21d側に配置され、使用者に触れられない状態であるため、掃除中に意図せず集塵装置30自体が分離することがない。
As described above, according to the vacuum cleaner main body 10, when the dust collector 30 is attached to the drive device 20, the dust collector 30 can be easily positioned on the drive device 20 (alignment before sliding). Wearability is improved.
Further, in a state where the dust collector 30 is attached to the drive device 20, the second lock mechanism M3 is arranged on the pipe portion 21d side of the drive device 20 like the inflow port 31ba, and cannot be touched by the user. Therefore, the dust collector 30 itself does not unintentionally separate during cleaning.

さらに、駆動装置20と集塵装置30とを着脱させる第1のロック機構M1を筐体21の両側面の一方側(本実施形態では右側面21ar側)に配置したため、ロックを解除しながら集塵装置30をスライドさせて取り外すことができ、使用性が向上している。この際、左右のどちらの手でも片手でロック解除および集塵装置30の駆動装置20からの取り外しが容易となる。換言すると、親指と他の4本の指で手をC字形に曲げて集塵装置30を掴んだときに、親指または親指以外の指(例えば人差し指)でロックを容易に解除できるのは、第1のロック機構M1を筐体21の両側面の一方側に配置したことによる。なお、筐体21から引っ掛け部21fを取り除き、この位置に第1のロック機構M1を設けた場合、右手であっても左手であってもロックを解除しながら集塵装置30をしっかり掴むことが難しくなる。 Further, since the first lock mechanism M1 for attaching / detaching the drive device 20 and the dust collector 30 is arranged on one side of both side surfaces of the housing 21 (on the right side surface 21ar side in this embodiment), the first lock mechanism M1 is arranged while releasing the lock. The dust device 30 can be slid and removed, improving usability. At this time, it is easy to unlock and remove the dust collector 30 from the drive device 20 with either one of the left and right hands. In other words, when the thumb and four other fingers bend the hand into a C shape and grab the dust collector 30, the lock can be easily released with the thumb or a finger other than the thumb (for example, the index finger). This is because the lock mechanism M1 of 1 is arranged on one side of both side surfaces of the housing 21. When the hooking portion 21f is removed from the housing 21 and the first lock mechanism M1 is provided at this position, the dust collector 30 can be firmly grasped while releasing the lock regardless of whether the user has a right hand or a left hand. It gets harder.

(第2実施形態)
第1実施形態では、駆動装置20と集塵装置30とを着脱させる第1のロック機構M1を筐体21の右側面21ar側に配置した場合を例示したが、第1のロック機構M1を筐体21の左側面側に配置してもよい。この場合でも、図9〜図12で説明したように左右どちらの手でも片手で集塵装置30を駆動装置20から容易に取り外すことができる。
(Second Embodiment)
In the first embodiment, the case where the first lock mechanism M1 for attaching / detaching the drive device 20 and the dust collector 30 is arranged on the right side surface 21ar side of the housing 21 is illustrated, but the first lock mechanism M1 is mounted on the housing. It may be arranged on the left side surface side of the body 21. Even in this case, as described with reference to FIGS. 9 to 12, the dust collector 30 can be easily removed from the drive device 20 with either one of the left and right hands.

(第3実施形態)
第1実施形態の掃除機本体10において、図5に示すように、駆動装置20の流出口21dcはパイプ部21dの真下位置よりも少し左右方向(図5では右側)へずれた位置に配置されているが、流出口21dcはパイプ部21dの真下位置に配置されてもよく、あるいは、流出口21dcはパイプ部21dよりも左右方向の外側に配置されてもよい。なおこれらの場合、集塵装置30の流入口31baは駆動装置20の流出口21dcと接続可能な位置に配置される。
また、第1実施形態では、流出口21dcがパイプ部21dの真下に向かって開口し、それによって塵埃含有空気が集塵容器31内へ周壁部31b(図8参照)の接線方向(第1の接線方向)から流入するようになっているが、流出口21dcはパイプ部21dの真下に向かって開口することに限定されない。例えば、流出口21dcは斜め下方に向かって開口し、その流出口21dcから塵埃含有空気が集塵容器31内へ周壁部31bの第2の接線方向から流入するように構成されてもよい。この場合、正面から視て、第2の接線方向は、第1の接線方向に対して鋭角に交わる方向である。なおこの場合も、集塵装置30の流入口31baは駆動装置20の流出口21dcと接続可能な位置に配置される。
(Third Embodiment)
In the vacuum cleaner main body 10 of the first embodiment, as shown in FIG. 5, the outlet 21dc of the drive device 20 is arranged at a position slightly shifted in the left-right direction (right side in FIG. 5) from the position directly below the pipe portion 21d. However, the outlet 21dc may be arranged at a position directly below the pipe portion 21d, or the outlet 21dc may be arranged outside the pipe portion 21d in the left-right direction. In these cases, the inflow port 31ba of the dust collector 30 is arranged at a position where it can be connected to the outflow port 21dc of the drive device 20.
Further, in the first embodiment, the outlet 21dc opens directly below the pipe portion 21d, whereby the dust-containing air enters the dust collecting container 31 in the tangential direction (see FIG. 8) of the peripheral wall portion 31b (see FIG. 8). The inflow is from the tangential direction), but the outlet 21dc is not limited to opening directly below the pipe portion 21d. For example, the outlet 21dc may be configured to open diagonally downward, and the dust-containing air may flow into the dust collecting container 31 from the outlet 21dc from the second tangential direction of the peripheral wall portion 31b. In this case, when viewed from the front, the second tangential direction is a direction that intersects the first tangential direction at an acute angle. Also in this case, the inflow port 31ba of the dust collector 30 is arranged at a position where it can be connected to the outflow port 21dc of the drive device 20.

(第4実施形態)
第1実施形態の掃除機本体10において、図8に示すように、駆動装置20の流出口21dcの接続面は集塵装置着脱時のスライド方向に対して傾斜状に設けられているが、流出口21dcの接続面はスライド方向と平行であってもよい。なお、集塵装置30の流入口31baの接続面は、この場合の駆動装置20の流出口21dcの接続面と平行である。この場合、流出口21dcの接続面と流入口31baの接続面とは、第1のロック機構M1にてロックされる直前(係止爪42bが係止凸部41に接触する)までは互いに接触せず、係止爪42bが係止凸部41の乗り越えを開始するあたりから互いに接触するようにすることが好ましい。このようにすることで、流入口31baの接続面とパッキン21ddの接続面との摺動面積が小さくなり、流入口31baがパッキン21ddに擦れることによるパッキン21ddの損傷が低減する。
(Fourth Embodiment)
In the vacuum cleaner main body 10 of the first embodiment, as shown in FIG. 8, the connection surface of the outlet 21 dc of the drive device 20 is provided so as to be inclined with respect to the slide direction when the dust collector is attached / detached. The connecting surface of the outlet 21dc may be parallel to the sliding direction. The connection surface of the inflow port 31ba of the dust collector 30 is parallel to the connection surface of the outflow port 21dc of the drive device 20 in this case. In this case, the connection surface of the outflow port 21dc and the connection surface of the inflow port 31ba are in contact with each other until immediately before being locked by the first locking mechanism M1 (the locking claw 42b contacts the locking convex portion 41). It is preferable that the locking claws 42b come into contact with each other from the point where the locking protrusions 41 start to get over. By doing so, the sliding area between the connecting surface of the inflow port 31ba and the connecting surface of the packing 21dd is reduced, and the damage to the packing 21dd due to the inflow port 31ba rubbing against the packing 21dd is reduced.

(第5実施形態)
第1実施形態では、掃除機本体10がハンドル21bを有し、使用者がハンドル21bを掴んで使用するスティックタイプまたはハンディタイプの電気掃除機の場合を例示したが、本発明はキャニスタータイプの電気掃除機にも適用可能である。このキャニスタータイプの電気掃除機の場合、掃除機本体は、電動送風機を内蔵した車輪付きの駆動装置と、駆動装置の上面に横倒し状態で装着される集塵装置とを備え、集塵装置の駆動装置への装着構造は第1実施形態と同様である。
(Fifth Embodiment)
In the first embodiment, the case where the vacuum cleaner main body 10 has a handle 21b and the user grips and uses the handle 21b is illustrated as a stick type or handy type vacuum cleaner, but the present invention is a canister type electric vacuum cleaner. It can also be applied to vacuum cleaners. In the case of this canister type vacuum cleaner, the vacuum cleaner main body is provided with a drive device with wheels having a built-in electric blower and a dust collector mounted on the upper surface of the drive device in a sideways state, and drives the dust collector. The mounting structure to the device is the same as that of the first embodiment.
