The duct inlet 13 is provided with a protective filter (not shown) to prevent foreign matter from entering the electric blower 14, and the protective filter is covered with a grid-like filter cover 17. The dust collector 10 is detachably attached to the front upper portion of the cleaner body 1 in a state of being inclined forward and downward. When the dust collector 10 is attached to the cleaner body 1, the dust collector 10 is fluidly connected to the introduction pipe 20 and the duct 21. The electric blower 14 is fluidly connected to the duct 21 and the high dust collection filter 29. When the dust collector 10 is attached to the cleaner body 1, a series of flow paths are formed from the hose attachment port 11 to the high dust filter 29. Although details are omitted, a packing (not shown) is provided at a connection portion (contact portion) of each component to maintain airtightness during operation. The vacuum cleaner body 1 has a structure for positioning the dust collector 10 and a structure for fixing the dust collector 10 so that the dust collector 10 can be easily kept airtight when the dust collector 10 is attached to the vacuum cleaner body 1.

The introduction pipe 20 is arranged not to the center of the vacuum cleaner main body 1 but to either the left or right side, as will be described in detail later, in order to make it easy to generate a swirling flow by inflowing air from the outer peripheral tangential direction of the dust collector 10. It is. Accordingly, the rotational direction of the swirl flow differs depending on the arrangement of the introduction pipe 20, but the rotation direction may be either (the swirl flow is clockwise when disposed on the left side). Further, for example, the introduction pipe 20 may be arranged on the left side (or the center) and the introduction pipe 20 may have a bent portion such that the introduction pipe outlet 12 is on the right side. However, the pressure loss tends to increase. . Therefore, the introduction pipe 20 is arranged as in the present embodiment, and in order to suppress the increase in pressure loss of the introduction pipe 20 as much as possible, the introduction pipe 20 is connected to the introduction pipe outlet 12 with a radius as large as possible from the hose attachment port 11. Yes. Further, the volume in the introduction pipe 20 is set as large as possible in order to suppress an increase in pressure loss as much as possible.

Further, the upper surface of the filter receiving portion 34 is provided with a bowl-shaped dust collecting filter receiving portion 34c, which is in contact with the lower surface side of a packing 32a provided on the outer periphery of the dust collecting filter 32 described later.
捕塵フィルタ３２は、通気面積を拡大するためにプリーツ状（山折り）に折られており、円状の枠体に接着されている。また、捕塵フィルタ３２は外周が鍔状の鍔部３２ｂとなっており、鍔部３２ｂの上下面にゴム部材等で成型されたパッキング３２ａを設けている。前述したように、フィルタ受け部３４に捕塵フィルタ３２を装着すると、パッキング３２ａの下面側とフィルタ受け部３４に備えた捕塵フィルタ受け部３４ｃとが接し、パッキング３２ａの上面側は、フィルタケース上部３３ａと接する。 The dust collection filter 32 is folded in a pleat shape (mountain fold) in order to enlarge the ventilation area, and is adhered to a circular frame. In addition, the dust collection filter 32 has a flange portion 32b having an outer periphery, and a packing 32a formed of a rubber member or the like is provided on the upper and lower surfaces of the flange portion 32b. As described above, when the dust collecting filter 32 is attached to the filter receiving portion 34, the lower surface side of the packing 32a is in contact with the dust collecting filter receiving portion 34c provided in the filter receiving portion 34, and the upper surface side of the packing 32a is the filter case. It contacts the upper part 33a.
前述したフィルタケース上部３３ａには、後方に爪部３６、前方にロック機構３７を備えており、爪部３６をフィルタケース下部３３ｂの係止部３３ｄに引っ掛け、前方のロック機構３７により外筒３０と固定が可能となる。よって、フィルタケース下部３３ｂに、フィルタ受け部３４、及び捕塵フィルタ３２を装着しフィルタケース上部３３ａを装着することで、捕塵フィルタ３２前後の気密を保持することができる。 The above-described filter case upper part 33a is provided with a claw part 36 on the rear side and a lock mechanism 37 on the front side. The claw part 36 is hooked on the engaging part 33d of the lower part of the filter case 33b. And can be fixed. Therefore, by attaching the filter receiving portion 34 and the dust collection filter 32 to the filter case lower portion 33b and attaching the filter case upper portion 33a, the airtightness around the dust collection filter 32 can be maintained.
フィルタケース上部３３ａの外観面には、上面に集塵装置１０を持つための持ち手５５、前方に掃除機本体１と固定するためのクランプ部５０、及びクランプ部５０を駆動するボタン６０を備えており、後方には電動送風機１４と流体的に接続される開口部３９を設けている（図１，２等参照）。開口部３９は保護フィルタ及びフィルタカバー１７を介しダクト２１と接続される。フィルタカバー１７は捕塵フィルタ３２と同様に、外周部の前後面にゴム部材等で成型されたパッキングを設け、開口部３９とダクト２１との間の気密を保持している。前述した持ち手５５は、集塵装置１０を掃除機本体１に装着する際に、掃除機本体１に設けた蓋体１９で覆うようになっている（図１，２参照）。これは、掃除機本体１を持ち運ぶ際に、本体ハンドル１８ではなく、持ち手５５を持ち上げることを防止するためである。蓋体１９は、回転軸部にねじりバネ（図示せず）を備えている。蓋体１９は、開いた状態（蓋体１９が直立した状態）から前方へ倒す際に捩りバネに捩り力が加わり、蓋体１９底面の前側に設けた爪部１９ａを前述したフィルタケース上部３３ａのクランプ部５０に引っ掛けて蓋体１９を閉じた状態となる。このとき、ねじりバネが戻ろうとする力も加わり、集塵装置１０を掃除機本体１側へ押し付けることができ、気密保持と集塵装置１０の固定を両立している。従って、蓋体１９を閉じた状態において、フィルタケース上部３３ａのボタン６０を押すと、クランプ部５０が解除され、蓋体１９がバネ力で持ち上がり持ち手５５が現われる。持ち手５５が現われた状態で、持ち手５５を引き上げることで集塵装置１０を容易に取り外すことができる。言い換えると、蓋体１９が開いた状態では、持ち手５５を引き上げても集塵装置１０が外れるため、持ち手５５では掃除機本体１を持ち上げられない構造となっており、誤動作の防止を行っている。 The outer surface of the filter case upper portion 33a includes a handle 55 for holding the dust collector 10 on the upper surface, a clamp portion 50 for fixing the cleaner main body 1 to the front, and a button 60 for driving the clamp portion 50. An opening 39 that is fluidly connected to the electric blower 14 is provided at the rear (see FIGS. 1 and 2). The opening 39 is connected to the duct 21 via the protective filter and the filter cover 17. As with the dust filter 32, the filter cover 17 is provided with packing formed of a rubber member or the like on the front and rear surfaces of the outer peripheral portion, and maintains airtightness between the opening 39 and the duct 21. The handle 55 described above is covered with a lid 19 provided on the cleaner body 1 when the dust collector 10 is attached to the cleaner body 1 (see FIGS. 1 and 2). This is to prevent lifting the handle 55 instead of the main body handle 18 when carrying the cleaner body 1. The lid body 19 is provided with a torsion spring (not shown) at the rotation shaft portion. When the lid 19 is tilted forward from the opened state (the lid 19 is in an upright state), a torsional force is applied to the torsion spring, and the claw portion 19a provided on the front side of the bottom surface of the lid 19 has the filter case upper portion 33a described above. The lid body 19 is closed by being hooked on the clamp portion 50. At this time, a force for returning the torsion spring is also applied, so that the dust collector 10 can be pressed against the cleaner body 1 side, and both airtight holding and fixing of the dust collector 10 are achieved. Accordingly, when the button 60 on the filter case upper portion 33a is pressed in a state in which the lid 19 is closed, the clamp portion 50 is released, and the lid 19 is lifted by the spring force and the handle 55 appears. With the handle 55 appearing, the dust collector 10 can be easily detached by pulling up the handle 55. In other words, when the lid 19 is open, the dust collector 10 is detached even if the handle 55 is pulled up. Therefore, the vacuum cleaner main body 1 cannot be lifted by the handle 55, thereby preventing malfunction. ing.
次に、内筒４０について、図１１、及び図１２を用いて説明する。図１１は図６におけるＢ−Ｂ断面図、図１２は内筒４０の分解図である。 Next, the inner cylinder 40 will be described with reference to FIGS. 11 and 12. 11 is a cross-sectional view taken along the line BB in FIG. 6, and FIG. 12 is an exploded view of the inner cylinder 40.
内筒４０は、略円筒状であり、先述したように外筒３０と同心円状となるように備えている。内筒４０は、上側に吸気部４２を備えた上部円筒４１、下側には筒体４６を内包した傘部４４で構成されている。上部円筒４１の吸気部４２は、格子状の枠体（支骨）によって形成されている。本実施例では上下方向の枠体（支骨）としているが、上下左右方向に枠体（支骨）のある格子状でも構わない。吸気部４２は、外周面にメッシュ部材４２ａが掛け渡されており、メッシュ部材４２ａは被覆またはインサート成型などによって枠体（支骨）に保持されている。吸気部４２にメッシュ部材４２ａを設けることで、上部内筒４１はフィルタ機能を有し、内筒４０内部への微細な塵埃の流入を抑制する。本実施例では、メッシュ部材４２ａは、ポリエステルを使用しているが、金属（例えば、ステンレス）でも良く、枠体（支骨）ではなく小径の貫通孔（金型で成型可能なφ２ｍｍ程度の孔）を複数設けた吸気部４２でも構わない。貫通孔は、枠体（支骨）にメッシュ部材４２ａを掛け渡した場合と違い、強度や破れに対し有効であり、二次成型が不要といった利点がある。しかし、貫通孔の径（開口面積）は、メッシュ部材４２ａの開口面積よりも大きくなると、内筒４０の内部への微細な塵埃の流入に対しては不利である。 The inner cylinder 40 has a substantially cylindrical shape, and is provided so as to be concentric with the outer cylinder 30 as described above. The inner cylinder 40 is composed of an upper cylinder 41 having an intake section 42 on the upper side and an umbrella section 44 containing a cylindrical body 46 on the lower side. The air intake portion 42 of the upper cylinder 41 is formed by a lattice-shaped frame body (support frame). In the present embodiment, the frame body (support frame) is arranged in the vertical direction, but it may be a lattice shape having the frame body (support frame) in the vertical and horizontal directions. A mesh member 42a is stretched over the outer peripheral surface of the intake portion 42, and the mesh member 42a is held on a frame (support frame) by covering or insert molding. By providing the mesh member 42 a in the intake portion 42, the upper inner cylinder 41 has a filter function and suppresses inflow of fine dust into the inner cylinder 40. In this embodiment, the mesh member 42a is made of polyester, but may be made of metal (for example, stainless steel), not a frame (support), but a small-diameter through hole (a hole having a diameter of about 2 mm that can be molded with a mold). ) May be provided. Unlike the case where the mesh member 42a is stretched over the frame (support frame), the through hole is effective for strength and tearing, and has an advantage that secondary molding is unnecessary. However, if the diameter (opening area) of the through hole is larger than the opening area of the mesh member 42a, it is disadvantageous for the inflow of fine dust into the inner cylinder 40.
上部内筒４１は先述したようにフィルタ受け部３４の略中心部の開口と連通している。本実施例では、内筒４０の上面にフランジ部４０ａを備え、フランジ部４０ａをフィルタ受け部３４の底面に固定する構成としているが、内筒４０の上面とフィルタ受け部３４の底面を一体に形成しても良い。また、フランジ部４０ａを設けずに、内筒３０がフィルタ受け部３４と着脱可能な構造にしても構わない。 As described above, the upper inner cylinder 41 communicates with the opening at the substantially central portion of the filter receiving portion 34. In this embodiment, the flange 40a is provided on the upper surface of the inner cylinder 40, and the flange 40a is fixed to the bottom surface of the filter receiver 34. However, the upper surface of the inner cylinder 40 and the bottom surface of the filter receiver 34 are integrated. It may be formed. Further, the inner cylinder 30 may be detachable from the filter receiving portion 34 without providing the flange portion 40a.
内筒４０の下部には、本発明の特徴とするところの傘部４４を備えている。傘部４４は、上部内筒４１と同心円状に設けており、略円筒状で上面が閉塞している。言い換えると、底面が開口し空間４４ａを有した形状である。そして、傘部４４の空間４４ａに内包するように傘部４４の傘部形状をオフセットした内傘部４５を設け、内傘部４５には、上面から下方に凸になるような筒体４６を設けている。筒体４６は、内傘部４５と同心円状に設けており、底面４７が閉塞し略半球状となっており、底面４７に向かって先細りになるようなテーパ形状である。筒体４６を先細りになるようなテーパ形状にすることで、外筒３０下部の先太りのテーパ部と合わせて下向きに拡大する容器形状となるため、ごみ捨ての際にごみが落下しやすくなる。また、筒体４６の表面には凹み部４８を設けており、凹み部４８に微細な塵埃を溜めることができ、微細な塵埃が吸気口４２から吹き抜ける量を低減することができる。この筒体４６は、集塵容積を拡大するために筒体４６の径を小さくし、傾斜角度を水平面から見て垂直に近づけても構わない。 The lower portion of the inner cylinder 40 is provided with an umbrella portion 44 as a feature of the present invention. The umbrella part 44 is provided concentrically with the upper inner cylinder 41 and is substantially cylindrical and has an upper surface closed. In other words, it has a shape with an open bottom and a space 44a. Then, an inner umbrella portion 45 is provided by offsetting the shape of the umbrella portion of the umbrella portion 44 so as to be included in the space 44a of the umbrella portion 44, and the inner umbrella portion 45 is provided with a cylindrical body 46 that protrudes downward from the upper surface. Provided. The cylindrical body 46 is provided concentrically with the inner umbrella portion 45, has a bottom surface 47 that is closed and substantially hemispherical, and has a tapered shape that tapers toward the bottom surface 47. By making the cylindrical body 46 taper so as to be tapered, it becomes a container shape that expands downward together with the tapered portion at the lower part of the outer cylinder 30, so that it becomes easy for the garbage to fall when throwing away the garbage. In addition, a concave portion 48 is provided on the surface of the cylindrical body 46, so that fine dust can be accumulated in the concave portion 48, and the amount of fine dust blown from the air inlet 42 can be reduced. In order to enlarge the dust collection volume, the diameter of the cylindrical body 46 may be reduced and the inclination angle of the cylindrical body 46 may be close to vertical as viewed from the horizontal plane.
詳細は後述するが、内傘部４５を傘部４４に内包し、上下方向に摺動する機構を設けることで、ごみ捨て時の排出のアシストを行う。内傘部４５は、吸引時などのごみ捨て時以外は傘部４４内に収まっており、ごみ捨て時に下方へ摺動することで、集塵装置１内の塵埃を押し出す。 Although details will be described later, the inner umbrella portion 45 is included in the umbrella portion 44, and a mechanism that slides in the vertical direction is provided, thereby assisting discharge when the garbage is discarded. The inner umbrella portion 45 is housed in the umbrella portion 44 except when dust is thrown away, such as when suctioned. The inner umbrella portion 45 slides downward when dust is thrown away, thereby pushing out dust in the dust collector 1.
内傘部４５の上下の摺動距離は、傘部４４の空間４４ａの高さ未満としている。言い換えると、内傘部４５の上面４５ａは、傘部４４の底面４４ｂを越えないようにしている。これは、ごみ捨て時の傘部４４の底面４４ｂと内傘部４５の上面４５ａとの間に隙間をなくすことで、底面４４ｂと上面４５ａとの間への塵埃の挟まりの恐れを抑制するためである。また、内傘部４５は、傘部４４内の空間４４ａを容易に摺動できる必要最小限のギャップを設けている。また、傘部４５は塵埃が堆積する部分であるため、内傘部４５とのギャップが小さすぎるとギャップ内に塵埃が噛み込み、摺動しにくくなることも考えられる。本実施例では、塵埃の噛み込みを考慮したギャップを設け、内傘部４５の外周に複数のリブ４５ｂを設けることで、ギャップを大きくしたことによる摺動する際のガタつきを低減している。更に、内傘部４５の底面に鍔部４５ｃを設け、内傘部４５が傘部４４の空間に収まった状態で、鍔部４５ｃと傘部４４の底面４４ｂが接するようにしている。これにより、塵埃吸引時の傘部４４と内傘部４５内との隙間への塵埃の入り込みを抑制している。 The vertical sliding distance of the inner umbrella portion 45 is less than the height of the space 44 a of the umbrella portion 44. In other words, the upper surface 45 a of the inner umbrella portion 45 does not exceed the bottom surface 44 b of the umbrella portion 44. This is to suppress the possibility of dust being caught between the bottom surface 44b and the top surface 45a by eliminating a gap between the bottom surface 44b of the umbrella portion 44 and the top surface 45a of the inner umbrella portion 45 when the garbage is discarded. is there. Further, the inner umbrella portion 45 is provided with a minimum necessary gap that can easily slide in the space 44 a in the umbrella portion 44. Moreover, since the umbrella part 45 is a part in which dust accumulates, if the gap with the inner umbrella part 45 is too small, the dust may be caught in the gap and become difficult to slide. In the present embodiment, a gap in consideration of the dust bite is provided, and a plurality of ribs 45b are provided on the outer periphery of the inner umbrella portion 45, thereby reducing backlash when sliding due to the increased gap. . Further, a collar portion 45 c is provided on the bottom surface of the inner umbrella portion 45 so that the collar portion 45 c and the bottom surface 44 b of the umbrella portion 44 are in contact with each other in a state where the inner umbrella portion 45 is accommodated in the space of the umbrella portion 44. Thereby, the entry of dust into the gap between the umbrella portion 44 and the inner umbrella portion 45 during dust suction is suppressed.
また、先述した外筒３０の形状に示したように、外筒３０の後方側には略Ｄ字にカットしているため、傘部４４及び内傘部４５の形状も、外筒３０の形状をオフセットするように略Ｄ字にカットしている。これにより、外筒３０と傘部４４との隙間を一定に保ち、隙間へのごみの挟まりを抑制することができる。 Further, as shown in the shape of the outer cylinder 30 described above, since the rear side of the outer cylinder 30 is cut into a substantially D-shape, the shape of the umbrella part 44 and the inner umbrella part 45 is also the shape of the outer cylinder 30. Is cut into a substantially D-shape so as to be offset. Thereby, the clearance gap between the outer cylinder 30 and the umbrella part 44 can be kept constant, and the jamming of the garbage to a clearance gap can be suppressed.
次に、本実施例での内傘部４５の摺動機構について説明する。摺動機構は、内傘部４５にバネ座を形成した構造となっており、内傘部４５の略中央にバネケース７０及びバネ軸７１を備えている。そして、傘部４４にはバネケース７０に入れ子状となるピストン部７２を備えている。バネ軸７１にはストッパー７３を固定できるようにネジで締結する構造となっており、バネケース７０に上方からバネ７４を挿入し、傘部４４と一体になった入れ子状のピストン部７２を装着した後、ストッパー７３をバネ軸７１に固定することで、内傘部４５の摺動機構が構成される。ストッパー７３は傘部４４の上面に備えたストッパー受け部７５まで摺動する。よって、前述したように摺動距離は傘部４４の空間４４ａの高さ未満であるため、ストッパー７３の高さも摺動距離と略同等となっている。そして内傘部４５に設けたバネケース７０の外周は、前述した筒体４６で覆い、内傘部４５にネジ等で締結している。 Next, the sliding mechanism of the inner umbrella part 45 in the present embodiment will be described. The sliding mechanism has a structure in which a spring seat is formed on the inner umbrella portion 45, and includes a spring case 70 and a spring shaft 71 at substantially the center of the inner umbrella portion 45. The umbrella portion 44 includes a piston portion 72 that is nested in the spring case 70. The spring shaft 71 has a structure that is fastened with a screw so that the stopper 73 can be fixed. The spring 74 is inserted into the spring case 70 from above, and a nested piston portion 72 integrated with the umbrella portion 44 is attached. Thereafter, the stopper 73 is fixed to the spring shaft 71 to constitute a sliding mechanism for the inner umbrella portion 45. The stopper 73 slides to a stopper receiving portion 75 provided on the upper surface of the umbrella portion 44. Therefore, as described above, since the sliding distance is less than the height of the space 44a of the umbrella portion 44, the height of the stopper 73 is substantially equal to the sliding distance. The outer periphery of the spring case 70 provided in the inner umbrella portion 45 is covered with the above-described cylinder 46 and fastened to the inner umbrella portion 45 with screws or the like.
このような摺動機構において、バネ７４が自然長に近い状態が、内傘部４５が最も飛び出した状態であり、底蓋３１を閉じるとバネ７４を縮めた状態になる。よって、ごみ捨て時に後述する底蓋３１のロックを解除すると、内傘部４５が下向きに飛び出し、内傘部４５で塵埃を押し出す。 In such a sliding mechanism, the state in which the spring 74 is close to the natural length is the state in which the inner umbrella portion 45 protrudes most, and the spring 74 is contracted when the bottom cover 31 is closed. Therefore, when the lock of the bottom lid 31 described later is released at the time of garbage disposal, the inner umbrella portion 45 pops out downward, and the inner umbrella portion 45 pushes out dust.
底蓋３１は、深さをもった皿状で中央部が突出している。中央部には突出した部分から凹みとなる窪み部３１ｂを備えている。底蓋３１は皿状にすることで強度を増している。また、窪み部３１ｂは、筒体４６の底面４７の球形状の球半径よりも大きくしており、窪み部３１ｂの深さは、底蓋３１が開状態（外筒３０の底面に対して垂直状態）で窪み部３１ｂに水平面ができないようにしている。言い換えると、窪み部３１ｂは極力浅くしている。これは、ごみ排出の際に窪み部３１ｂに塵埃が残らないようにするためである。また、底蓋３１内には、図に示すような底面リブ３１ｃを設けている。これは、外筒３０の下部テーパ内を旋回する塵埃の回転を止めて、底面リブ３１ｃを基点に塵埃を圧縮するためである。本実施例では、底面リブ３１は、底蓋３１内の外周側に底蓋３１の深さと略同等の高さから、中心に向うほど低くなるような略三角形状をしており、前側と左右に配置している。このような底面リブ３１ｃは、集塵容積や傘部４４の形状等により調整をおこなっているため、形状はこの限りではない。また、本実施例では、窪み部３１ｂを別体で形成しており、底蓋３１開閉での筒体４６との摩擦による部材の磨耗を低減するようにＰＯＭなどの材料を用いているが、一体で成形しても構わない。 The bottom cover 31 is a dish shape with a depth, and the center part protrudes. The center part is provided with a hollow part 31b which becomes a dent from the protruding part. The bottom lid 31 is increased in strength by having a dish shape. The hollow portion 31b is larger than the spherical sphere radius of the bottom surface 47 of the cylindrical body 46, and the depth of the hollow portion 31b is determined when the bottom lid 31 is open (perpendicular to the bottom surface of the outer tube 30). In the state), the hollow portion 31b is not allowed to have a horizontal surface. In other words, the recess 31b is as shallow as possible. This is to prevent dust from remaining in the recess 31b when discharging the dust. Also, a bottom rib 31c as shown in the figure is provided in the bottom lid 31. This is to stop the rotation of the dust swirling in the lower taper of the outer cylinder 30 and compress the dust with the bottom rib 31c as a base point. In the present embodiment, the bottom rib 31 has a substantially triangular shape on the outer peripheral side in the bottom cover 31 so as to decrease from the height substantially equal to the depth of the bottom cover 31 toward the center. Is arranged. Since the bottom rib 31c is adjusted by the dust collection volume, the shape of the umbrella portion 44, and the like, the shape is not limited to this. Further, in this embodiment, the hollow portion 31b is formed as a separate body, and a material such as POM is used so as to reduce wear of the member due to friction with the cylindrical body 46 when the bottom lid 31 is opened and closed. You may shape | mold integrally.
以上のようなごみ排出機構において、ごみ捨て時の動作を図１３、及び図１４を用いて説明する。図１３は、底蓋３１を閉じた状態の図５に示すＡ−Ａ断面図、図１４はごみを排出した後（底蓋３１が開いた状態）の図５に示すＡ−Ａ断面図である。 In the above-described waste discharging mechanism, the operation when throwing away the waste will be described with reference to FIGS. 13 and 14. FIG. 13 is a cross-sectional view taken along line AA shown in FIG. 5 with the bottom cover 31 closed, and FIG. 14 is a cross-sectional view taken along line AA shown in FIG. 5 after the waste is discharged (the state where the bottom cover 31 is opened). is there.
底蓋３１は、集塵装置１０に設けた取っ手３５上部に備えたごみ捨てボタン３５ａを押下ことで解除される。底蓋３１は取っ手３５の反対側に回転軸３１ａを備え、取っ手３５側には底蓋３１の開閉機構を備えている。取っ手３５の上部に備えたごみ捨てボタン３５ａは、取っ手３５内のロッド８０を下向きに動かし、取っ手３５下部のスライドクランプ８１を押す。詳細は省略するが、スライドクランプ８１は、ロッド８０と斜面で接触しているため、ロッド８０の上下方向の動きをスライドクランプ８１で左右方向に変換し、スライドクランプ８０に設けたバネを縮める。そして、底蓋３１に設けたクランプ受け８２からスライドクランプ８１の爪部８３が外れ、底蓋３１が開口する。底蓋３１の回転軸３１ａには捩りバネを備えており、底蓋２１はバネ力で開く。ごみ捨てボタン３５ａの押下を解除すると、スライドクランプ８１に設けたバネが自然長に戻るため、ロッド８０は上方に戻り、スライドクランプ８０はごみ捨てボタン３５ａの押下前の位置に戻る。 The bottom cover 31 is released by pressing a garbage disposal button 35 a provided on the upper part of the handle 35 provided in the dust collector 10. The bottom cover 31 includes a rotating shaft 31a on the opposite side of the handle 35, and includes an opening / closing mechanism for the bottom cover 31 on the handle 35 side. The waste disposal button 35 a provided at the upper part of the handle 35 moves the rod 80 in the handle 35 downward and pushes the slide clamp 81 at the lower part of the handle 35. Although details are omitted, since the slide clamp 81 is in contact with the rod 80 on the inclined surface, the vertical movement of the rod 80 is converted into the horizontal direction by the slide clamp 81 and the spring provided in the slide clamp 80 is contracted. And the nail | claw part 83 of the slide clamp 81 remove | deviates from the clamp receiver 82 provided in the bottom cover 31, and the bottom cover 31 opens. The rotating shaft 31a of the bottom cover 31 is provided with a torsion spring, and the bottom cover 21 is opened by a spring force. When the depression of the waste disposal button 35a is released, the spring provided in the slide clamp 81 returns to its natural length, so that the rod 80 returns upward, and the slide clamp 80 returns to the position before the depression of the waste disposal button 35a.
以上のような、内傘部摺動機構及び底蓋ロック機構による、ごみ捨て時の各機構部の動きを以下に説明する。 The movement of each mechanism part at the time of garbage disposal by the inner umbrella part sliding mechanism and the bottom lid locking mechanism as described above will be described below.
ごみ捨ての際、集塵装置１０の取っ手３５上部のごみ捨てボタン３５ａを押すと、底蓋３１のクランプ受け８２に掛かった爪部８３がスライドし、底蓋３１は外力を受けることで回転軸３１ａを中心に開くようになる。外力は、内傘部４５及び筒体４６が下方向に動くことによる底蓋３１を下向きに押す力と、底蓋３１の回転軸３１ａに設けた捩りバネの反発力である。本実施例では、底蓋３１の回転軸３１ａに捩りバネを設けているが、捩りバネを設けず内傘部４５及び筒体４６の摺動による底蓋３１を押す力のみでも底蓋３１を開くことができる。 When throwing away the garbage, if the dust disposal button 35a on the upper part of the handle 35 of the dust collector 10 is pushed, the claw 83 that is hooked on the clamp receiver 82 of the bottom lid 31 slides, and the bottom lid 31 receives the external force to rotate the rotating shaft 31a. Open to the center. The external force is a force that pushes the bottom cover 31 downward as the inner umbrella portion 45 and the cylindrical body 46 move downward, and a repulsive force of a torsion spring provided on the rotation shaft 31 a of the bottom cover 31. In this embodiment, a torsion spring is provided on the rotating shaft 31a of the bottom cover 31, but the bottom cover 31 is not provided with a torsion spring and the bottom cover 31 can be attached only by a force pushing the bottom cover 31 due to sliding of the inner umbrella portion 45 and the cylindrical body 46. Can be opened.
底蓋３１が開くと同時に、バネ７４によって内傘部４５及び筒体４６が下向きに飛び出す。これにより、内筒４０の一部である内傘部４５は、底蓋３１が閉じた状態の位置よりも底蓋３１が開いた状態の位置が、外筒３０の下面の開口寄りの位置となる。 Simultaneously with the opening of the bottom cover 31, the inner umbrella portion 45 and the cylindrical body 46 jump out downward by the spring 74. Thereby, the inner umbrella part 45 which is a part of the inner cylinder 40 has a position where the bottom cover 31 is opened more than a position where the bottom cover 31 is closed and a position closer to the opening on the lower surface of the outer cylinder 30. Become.
ごみ捨て後、底蓋３１を閉じる際、下方に飛び出した筒体４６の底面４７と、底蓋３１の中央に設けた窪み部３１ｂが接触し、内傘部４５及び筒体４６は上方へ押される。筒体４６の底面４７と窪み部３１ｂは球状に接するため、底蓋３１を閉じる動作で底蓋３１の角度が変わっても、筒体４６の底面４７と窪み部３１ｂとの接触面積を一定に保つことができ、また、曲面同士を接触させることで常に垂直方向に力が加わるため、内傘部４５は傘部内４４にスムーズに収まる。底蓋３１に窪み部３１ｂを設けず平面で接触させる場合は力が加わる方向が平面に対し垂直になるため内傘部４５が垂直に戻り難く、底蓋３１が閉め難くなる。よって、本発明のように窪み部３１ｂを設ける必要がある。そして、底蓋３１を略水平状態まで閉じると、クランプ受け８２が爪部８３と接触し、スライドクランプ８１は、スライドクランプ８１に設けたバネが縮む方向に移動し、爪部８３がクランプ受け８２を乗り越えた時点でバネが戻り、底蓋３１は気密を保持した状態でロックされる。 When the bottom lid 31 is closed after throwing away the garbage, the bottom surface 47 of the cylindrical body 46 that protrudes downward contacts the recessed portion 31b provided in the center of the bottom lid 31, and the inner umbrella portion 45 and the cylindrical body 46 are pushed upward. . Since the bottom surface 47 of the cylindrical body 46 and the recessed portion 31b are in contact with each other in a spherical shape, the contact area between the bottom surface 47 of the cylindrical body 46 and the recessed portion 31b is kept constant even if the angle of the bottom lid 31 is changed by closing the bottom lid 31. In addition, since the force is always applied in the vertical direction by bringing the curved surfaces into contact with each other, the inner umbrella portion 45 fits smoothly in the umbrella portion 44. When the bottom cover 31 is not provided with the recess 31b and is brought into contact with a flat surface, the direction in which the force is applied is perpendicular to the flat surface, so that the inner umbrella portion 45 is difficult to return vertically and the bottom cover 31 is difficult to close. Therefore, it is necessary to provide the recess 31b as in the present invention. When the bottom lid 31 is closed to a substantially horizontal state, the clamp receiver 82 comes into contact with the claw portion 83, the slide clamp 81 moves in a direction in which the spring provided on the slide clamp 81 contracts, and the claw portion 83 is moved to the clamp receiver 82. The spring returns to the point where it has been passed over, and the bottom lid 31 is locked in an airtight state.
以上のような、外筒３０、内筒４０、捕塵フィルタ３２、フィルタケース３３、底蓋３１を組み合わせ、塵埃を吸引できる状態での集塵装置１０について、図１１及び図１２を用いて説明する。本実施例において、掃除機本体１のホース取り付け口１１から電動送風機１４へ至るまでの流路で、ホース取り付け口１１の断面積が最小となるように各部の寸法を設定している。ホース取り付け口１１の断面積は、約１５００ｍｍ2（約φ４３ｍｍ）である。集塵装置１０の出口は上部内筒４１の内側開口面積となるので、開口面積を１５００ｍｍ2以上に設定するために、上部内筒４１の外径をφ５５ｍｍとして、肉厚を２ｍｍで内径はφ５１ｍｍとなり開口面積は約２０００ｍｍ2となる。 The dust collector 10 in a state where the outer cylinder 30, the inner cylinder 40, the dust collecting filter 32, the filter case 33, and the bottom cover 31 as described above are combined and can suck dust will be described with reference to FIGS. To do. In the present embodiment, the dimensions of each part are set so that the cross-sectional area of the hose attachment port 11 is minimized in the flow path from the hose attachment port 11 of the cleaner body 1 to the electric blower 14. The cross-sectional area of the hose attachment port 11 is about 1500 mm 2 (about φ43 mm). Since the outlet of the dust collector 10 is the inner opening area of the upper inner cylinder 41, in order to set the opening area to 1500 mm 2 or more, the outer diameter of the upper inner cylinder 41 is 55 mm, the wall thickness is 2 mm, and the inner diameter is 51 mm. Thus, the opening area is about 2000 mm 2 .
集塵装置１０の入口である流入口管３８は、接線方向に流入するために流入管３８の出口で絞り３８ｂを設けている。絞り３８ｂは外筒３０の円弧を延長し、流入管の開口部３８ａから投影した際、上部内筒４１が隠れる範囲までとしている。この絞り３８ｂにより、開口した円弧の長さと流入管３８高さの積を１５００ｍｍ2以上とするためには、流入管３８の高さは約４７ｍｍが必要となる。このように、流入管３８の高さはホース取り付け口１１の断面積を基準に設定しているが、外筒３０の径を大きくすることで流入管３８の高さを低くすることも可能である。しかしながら、掃除機本体１をコンパクトに設計するためには、外筒３０の径を小さくする必要があり、本実施例では外筒３０の径をφ１００ｍｍに設定し、各部の寸法を設定している。従って、外筒３０の径や流入管３８の高さなどはこの限りでなく、掃除機本体１のデザイン等で所望の寸法を決定すれば良い。 The inlet pipe 38 which is the inlet of the dust collector 10 is provided with a throttle 38b at the outlet of the inlet pipe 38 in order to flow in the tangential direction. The diaphragm 38b extends the arc of the outer cylinder 30 to the extent that the upper inner cylinder 41 is hidden when projected from the opening 38a of the inflow pipe. In order to make the product of the length of the opened arc and the height of the inflow pipe 38 to be 1500 mm 2 or more by the throttle 38b, the height of the inflow pipe 38 needs to be about 47 mm. As described above, the height of the inflow pipe 38 is set based on the cross-sectional area of the hose attachment port 11, but the height of the inflow pipe 38 can be reduced by increasing the diameter of the outer cylinder 30. is there. However, in order to design the vacuum cleaner body 1 in a compact manner, it is necessary to reduce the diameter of the outer cylinder 30. In this embodiment, the diameter of the outer cylinder 30 is set to φ100 mm, and the dimensions of each part are set. . Therefore, the diameter of the outer cylinder 30 and the height of the inflow pipe 38 are not limited to this, and a desired dimension may be determined by the design of the cleaner body 1 or the like.
上部内筒４１の高さにおいても、吸気口４２の総面積が１５００ｍｍ2以上となるように設定する。吸気口４２の外周にはメッシュ部材４２ａを設けるため、メッシュ部材４２ａの開口率により、上部内筒４１の高さは変化する。本実施例では、メッシュサイズを８０メッシュ〜１００メッシュとし、開口率は４６％前後である。よって、吸気口４２の総面積を約３０００ｍｍ2となるように設定すれば良く、上部内筒４１の高さは流入管３８高さと略同等としている。吸気口４２は縦方向の複数の柱で構成しているが、上部内筒４１の強度を増すために格子状にしても良く、同等の吸気口４２の総面積や強度が得られる形状であればこの限りではない。 Even at the height of the upper inner cylinder 41, the total area of the air inlets 42 is set to be 1500 mm 2 or more. Since the mesh member 42a is provided on the outer periphery of the air inlet 42, the height of the upper inner cylinder 41 varies depending on the opening ratio of the mesh member 42a. In this embodiment, the mesh size is 80 mesh to 100 mesh, and the aperture ratio is around 46%. Therefore, the total area of the air inlet 42 may be set to be about 3000 mm 2, and the height of the upper inner cylinder 41 is substantially equal to the height of the inflow pipe 38. The air inlet 42 is composed of a plurality of columns in the vertical direction, but may be formed in a lattice shape in order to increase the strength of the upper inner cylinder 41, as long as the total area and strength of the equivalent air inlet 42 can be obtained. This is not the case.
先述したように、内筒４０の下側には傘部４４を設けている。傘部４４の外周は集塵装置１０内の下方向で外筒３０と内筒４０の間に形成される塵埃集塵部への入口であり、外筒３０のテーパ部内に傘部４４を設けることで、塵埃集塵部の面積が徐々に拡大するため塵埃を搬送しやすい。また、塵埃集塵部に流れた空気は、すべて上部内筒４１の吸気口４２を通るように流れるため、この空気の流れによって、ごみは上部内筒４１側へ移動するような動きになるが、塵埃集塵部から見ると出口（塵埃集塵部入口）が徐々に狭まっているため、塵埃が上部内筒４１へ戻りにくくなる。本実施例のテーパ部は、集塵装置１０をコンパクトにするために最大径をφ１２０ｍｍとしているがこの限りでなく、最大径を更に大きくしても良い。最大径を大きくすることで、集塵容積を拡大でき、より多くの塵埃を堆積することができる。 As described above, the umbrella portion 44 is provided below the inner cylinder 40. The outer periphery of the umbrella part 44 is an entrance to the dust collecting part formed between the outer cylinder 30 and the inner cylinder 40 in the downward direction in the dust collector 10, and the umbrella part 44 is provided in the tapered part of the outer cylinder 30. As a result, the area of the dust collecting portion gradually increases, so that it is easy to carry the dust. In addition, since all the air that has flowed to the dust collecting portion flows so as to pass through the air inlet 42 of the upper inner cylinder 41, the movement of dust moves toward the upper inner cylinder 41 due to this air flow. When viewed from the dust collecting portion, the outlet (the dust collecting portion inlet) is gradually narrowed, so that it is difficult for the dust to return to the upper inner cylinder 41. The taper portion of the present embodiment has a maximum diameter of φ120 mm in order to make the dust collector 10 compact, but is not limited to this, and the maximum diameter may be further increased. By increasing the maximum diameter, the dust collection volume can be expanded and more dust can be accumulated.
傘部４４は、外径がφ７８ｍｍとしており、外筒３０の内壁面と傘部４４との外周との隙間は約１０ｍｍとしている。この隙間を狭くすると塵埃集塵部から塵埃が戻る現象を更に抑制でき、塵埃分離性能の向上が見込める。しかし、隙間を通過できず塵埃収容部に収まらない大きさの異物を吸引する場合も在り得るため、隙間を狭くし過ぎず、塵埃集塵部から塵埃が戻り過ぎない隙間として、約１０ｍｍに設定している。 The umbrella portion 44 has an outer diameter of φ78 mm, and the gap between the inner wall surface of the outer cylinder 30 and the outer periphery of the umbrella portion 44 is about 10 mm. When this gap is narrowed, the phenomenon that dust returns from the dust collecting portion can be further suppressed, and the dust separation performance can be improved. However, since there may be cases where foreign objects of a size that cannot pass through the gap and cannot be accommodated in the dust container, the gap is not too narrow, and the gap that does not return too much dust from the dust collector is set to about 10 mm. doing.
塵埃集塵部を形成するテーパ部の高さは約５０ｍｍとしているが、更に高くするほど集塵容積が拡大できる上、塵埃分離性能も向上できる。しかし、本実施例においては、掃除機本体１のコンパクト化に際し、集塵装置１０の大きさ（高さ）を予め設定しており、流入管３８の高さや捕塵フィルタ３２の大きさ（高さ）を基準としているため、テーパ部の高さを約５０ｍｍとしているが、この限りではない。 The height of the tapered portion forming the dust collecting portion is about 50 mm, but the dust collection volume can be increased and the dust separation performance can be improved as the height is further increased. However, in the present embodiment, when the vacuum cleaner body 1 is made compact, the size (height) of the dust collector 10 is set in advance, and the height of the inflow pipe 38 and the size (high) of the dust collecting filter 32 are set. Therefore, the height of the taper portion is about 50 mm, but this is not a limitation.
傘部４４は、内傘部４５を収納した状態で肉厚を含め高さを約２１ｍｍとして、摺動距離は約１５ｍｍとしている。テーパ部の高さを約５０ｍｍとしているため、傘部４４の底面から外筒３０のテーパ部の底面までの高さは約２９ｍｍである。吸引した塵埃は傘部４４の底面に圧縮されるため、摺動距離は傘部４４の底面からの距離の１／２以上としている。この摺動距離は、ごみ捨て時に内傘部４５でごみを押し出す際に、堆積した塵埃の高さの半分以上を外筒３０底面から露出させるためであり、ごみが落下しやすくなる。また、外筒３０と筒体４６から形成される空間は、下向きに広がった形状であるため、容易に塵埃を押し出すことができる。更に、筒体４６の先細り形状も下向きに摺動することで塵埃を押し出す効果が得られる。 The umbrella portion 44 is about 21 mm in height including the wall thickness in a state where the inner umbrella portion 45 is housed, and the sliding distance is about 15 mm. Since the height of the taper portion is about 50 mm, the height from the bottom surface of the umbrella portion 44 to the bottom surface of the taper portion of the outer cylinder 30 is about 29 mm. Since the sucked dust is compressed to the bottom surface of the umbrella portion 44, the sliding distance is set to be 1/2 or more of the distance from the bottom surface of the umbrella portion 44. This sliding distance is for exposing more than half of the height of the accumulated dust from the bottom surface of the outer cylinder 30 when the dust is pushed out by the inner umbrella portion 45 when throwing away the dust, and the dust easily falls. Moreover, since the space formed by the outer cylinder 30 and the cylindrical body 46 has a shape that extends downward, dust can be easily pushed out. Furthermore, the effect of pushing out dust can be obtained by sliding the tapered shape of the cylindrical body 46 downward.
このような、ごみ排出機構を設けることで、傘部４４底面を超えて、傘部外周と外筒との間まで塵埃が堆積しても、塵埃を容易に押し出せるため、ごみ捨てを促すごみ捨てラインの位置を高く設定でき、コンパクトな集塵装置１０ながら、集塵容積、または吸引可能な塵埃の量を多くすることができる。 By providing such a dust discharge mechanism, even if dust accumulates between the outer periphery of the umbrella portion and the outer cylinder beyond the bottom surface of the umbrella portion 44, dust can be easily pushed out, so that a dust disposal line that facilitates waste disposal Can be set high, and the dust collecting volume or the amount of dust that can be sucked can be increased while the compact dust collecting device 10 is used.
このような構造の集塵装置１０を備えることで、塵埃を含んだ空気は次のような流れとなる。図１１及び図１３に示す矢印で掃除機運転時の集塵装置１０内の流れを説明する。 By providing the dust collector 10 having such a structure, the air containing the dust flows as follows. The flow in the dust collector 10 during vacuum cleaner operation will be described with the arrows shown in FIGS. 11 and 13.
操作部４に設けられた操作ボタン５により使用者が運転を開始すると、電動送風機１４が回転し空気を吸い込む。吸い込んだ空気は、導入管２０を経て、流入管３８より集塵装置２０内に流入する。外筒３０の接線方向から流入した空気は、旋回流となり、塵埃に遠心力が働き、塵埃と空気は分離される。つまり、塵埃集塵部１０内の上部である塵埃分離部にて、塵埃と空気とは分離される。分離された空気の多くは上部内筒４１に設けた吸気口４２より内筒４０の内部に流入する。そして、空気はフィルタ受け部３４を経て捕塵フィルタ３２を通過し、フィルタケース上部３３ａの開口を経て、電動送風機１４へ至る。このとき、吸気口４２のメッシュ部材４２ａを通過した微細な塵埃は、捕塵フィルタ３２で捕集される。 When the user starts operation with the operation button 5 provided on the operation unit 4, the electric blower 14 rotates and sucks air. The sucked air flows into the dust collector 20 through the inlet pipe 20 through the inlet pipe 20. The air flowing in from the tangential direction of the outer cylinder 30 becomes a swirling flow, centrifugal force acts on the dust, and the dust and air are separated. That is, the dust and the air are separated at the dust separation unit, which is the upper part in the dust collection unit 10. Most of the separated air flows into the inner cylinder 40 from the air inlet 42 provided in the upper inner cylinder 41. Then, the air passes through the dust collecting filter 32 through the filter receiving portion 34, reaches the electric blower 14 through the opening of the filter case upper portion 33 a. At this time, fine dust that has passed through the mesh member 42 a of the air inlet 42 is collected by the dust collection filter 32.
一方、遠心力で分離された塵埃は、重力と一部の空気流により外筒３０と傘部４４との間の塵埃集塵部入口を通り、塵埃集塵部内に搬送される。このとき、塵埃には遠心力が働いているため、塵埃集塵部内で旋回する。そして、掃除機の使用を続けると、徐々に塵埃が堆積し、底蓋３１に設けた底面リブ３１ｃを基点に塵埃の旋回が止まり、ドーナツ状に堆積する。集塵室内に流入した空気は、筒体４６、内傘部４５の空間４４ａ形状に沿って、傘部４４の外周付近から上部内筒４１側へ流れる。この空気の流れによる、塵埃の上部内筒４１側への戻りを抑制するためには傘部４４の深さが必要である。本発明は、塵埃を押し出すために、摺動距離を大きくしているため、ごみ排出効果と同時に傘部４４に十分な深さを設けることができる。 On the other hand, the dust separated by the centrifugal force passes through the dust collecting portion entrance between the outer cylinder 30 and the umbrella portion 44 by gravity and a part of the air flow, and is conveyed into the dust collecting portion. At this time, since centrifugal force acts on the dust, the dust rotates in the dust collecting portion. When the vacuum cleaner continues to be used, dust gradually accumulates, and the dust stops turning from the bottom rib 31c provided on the bottom cover 31 and accumulates in a donut shape. The air that has flowed into the dust collection chamber flows from the vicinity of the outer periphery of the umbrella portion 44 toward the upper inner cylinder 41 along the shape of the space 44 a of the cylinder body 46 and the inner umbrella portion 45. In order to suppress the return of dust to the upper inner cylinder 41 due to the air flow, the depth of the umbrella portion 44 is necessary. In the present invention, since the sliding distance is increased in order to push out dust, the umbrella portion 44 can be provided with a sufficient depth at the same time as the dust discharge effect.
そして、塵埃が傘部４４の上面以下に設けたごみ捨てラインまで達したら、ごみ捨てを行う。ごみ排出機構は前述した通りであり、吸引した塵埃の量が少ない場合でも、内傘部４５のごみ排出機構、及び外筒３０のテーパ形状により、塵埃の排出は可能である。 When the dust reaches the garbage disposal line provided below the upper surface of the umbrella portion 44, the garbage is discarded. The dust discharge mechanism is as described above. Even when the amount of dust sucked is small, dust can be discharged by the dust discharge mechanism of the inner umbrella portion 45 and the tapered shape of the outer cylinder 30.
以上のようなごみ排出機構を集塵装置１０に設けることで、ごみ捨て時、集塵装置１０内の塵埃を容易に排出することができる。また、ごみ排出後、塵埃が傘部４４内や傘部４４と外筒３０との間への挟まりを大きく軽減できるため、ごみ捨て後に集塵装置１０内の残留したごみを使用者が取り除く等の手間を軽減でき、また、ごみに直接手で触れることを抑制できるため、使い勝手を大きく向上することができる。
（第二の実施形態）
次に、第二の実施形態について図面を参照しながら詳細に説明するが、掃除機本体１、及び集塵装置１０である外筒３０、内筒４０等の形状は第一の実施形態と基本的に同様である。本実施例は、ごみ排出機構に特徴を持っており、以下では内筒４０の構造について説明する。
By providing the dust collecting mechanism 10 as described above, the dust in the dust collecting device 10 can be easily discharged when the dust is discarded. In addition, since dust can be greatly reduced from being trapped in the umbrella portion 44 or between the umbrella portion 44 and the outer cylinder 30 after the waste is discharged, the user can remove the dust remaining in the dust collector 10 after throwing away the waste. Since the time and effort can be reduced and direct contact with garbage can be suppressed, the usability can be greatly improved.
(Second embodiment)
Next, the second embodiment will be described in detail with reference to the drawings. The shapes of the vacuum cleaner main body 1 and the outer cylinder 30 and the inner cylinder 40 that are the dust collector 10 are the same as those of the first embodiment. The same. The present embodiment is characterized by a dust discharge mechanism, and the structure of the inner cylinder 40 will be described below.
図１５は、第二の実施形態における集塵装置１０の略中央の断面図を示した図である。内筒４０は、筒状の上部内筒４１と傘部４４で形成されている。傘部４４は上面が閉塞し、下面が開口した略円筒状であり、傘部４４内の空間４４ａには、上面から下方に凸になるような筒体４６を設けている。筒体４６は、内傘部４４と同心円状に設けており、底面４７が球状となっており、底面４７に向かって先細りになるようなテーパ形状である。テーパ形状にすることで、外筒３０下部のテーパ部と合わせて下向きに拡大する容器形状となるため、ごみ捨ての際に塵埃が落下しやすくなる。また、筒体４６表面には凹み部４８を設けており、凹み部４８に微細な塵埃を溜めることができ、微細な塵埃が吸気口４２から吹き抜ける量を低減することができる。この筒体４６は、集塵容積を拡大するために筒体４６の径を小さくし、傾斜角度を水平面から見て垂直に近づけても構わない。 FIG. 15 is a cross-sectional view of the approximate center of the dust collector 10 in the second embodiment. The inner cylinder 40 is formed by a cylindrical upper inner cylinder 41 and an umbrella portion 44. The umbrella portion 44 has a substantially cylindrical shape with the upper surface closed and the lower surface opened, and a space 46 a in the umbrella portion 44 is provided with a cylindrical body 46 that protrudes downward from the upper surface. The cylindrical body 46 is provided concentrically with the inner umbrella portion 44, has a spherical bottom surface 47, and has a tapered shape that tapers toward the bottom surface 47. By making the taper shape, it becomes a container shape that expands downward together with the taper portion at the lower part of the outer cylinder 30, so that dust is likely to fall when the garbage is discarded. In addition, a concave portion 48 is provided on the surface of the cylindrical body 46, so that fine dust can be accumulated in the concave portion 48, and the amount of fine dust blowing through the air inlet 42 can be reduced. In order to enlarge the dust collection volume, the diameter of the cylindrical body 46 may be reduced and the inclination angle of the cylindrical body 46 may be close to vertical as viewed from the horizontal plane.
傘部４４は、上部内筒４２と別体で形成されており、傘部４４中央に摺動機構のバネ７４を収納するバネケース７０を備え、中心軸上にネジ穴を設けたバネ軸７１を備えている。上部内筒４２には、別体または一体で形成されたピストン部７２を備えたおり、ピストン部７２はバネケース７０と入れ子状になっている。また、ピストン部７２は筒状で、筒状の内部にバネ座を備えている。このような構成の内筒４０は、傘部４４に設けたバネケース７０にバネ７４を収納し、上部内筒４１のピストン部７２をバネケース７０に挿入し、ピストン部７２の上方から、ストッパー７３を挿入し、ストッパー７３をバネケース７０に設けたバネ軸７１にネジ等で締結することで、傘部４４全体を上下に摺動できる機構となる。 The umbrella portion 44 is formed separately from the upper inner cylinder 42, and includes a spring case 70 that houses a spring 74 of a sliding mechanism at the center of the umbrella portion 44, and a spring shaft 71 having a screw hole on the center axis. I have. The upper inner cylinder 42 is provided with a piston part 72 formed separately or integrally, and the piston part 72 is nested with the spring case 70. The piston portion 72 is cylindrical and has a spring seat inside the cylinder. In the inner cylinder 40 having such a configuration, the spring 74 is accommodated in the spring case 70 provided in the umbrella portion 44, the piston portion 72 of the upper inner cylinder 41 is inserted into the spring case 70, and the stopper 73 is inserted from above the piston portion 72. By inserting and fastening the stopper 73 to the spring shaft 71 provided on the spring case 70 with a screw or the like, the entire umbrella portion 44 can be slid up and down.
このような摺動機構において、バネが自然長に近い状態で傘部４４が最も飛び出した状態であり、底蓋３１を閉じるとバネ７４を縮めた状態になる。よって、ごみ捨て時に底蓋３１のロックを解除すると、傘部４４が下向きに飛び出し、傘部４４で塵埃を押し出す。また、上部内筒４１の底部４１ａにはパッキング４１ｂを備えており、底蓋３１を閉じた状態で上部内筒４１と傘部４４との接続部の気密を保持している。これにより、上部内筒４１と傘部４４との接続部への塵埃の挟まりを防止している。 In such a sliding mechanism, the umbrella portion 44 protrudes most when the spring is close to the natural length. When the bottom cover 31 is closed, the spring 74 is contracted. Therefore, when the bottom cover 31 is unlocked when the trash is thrown away, the umbrella portion 44 jumps downward, and the umbrella portion 44 pushes out dust. Further, the bottom 41a of the upper inner cylinder 41 is provided with a packing 41b, and the connection between the upper inner cylinder 41 and the umbrella part 44 is kept airtight with the bottom lid 31 closed. This prevents dust from being caught in the connection portion between the upper inner cylinder 41 and the umbrella portion 44.
本実施例の特徴は、傘部４４全体が摺動することである。傘部４４全体を摺動させることで、外筒３０と傘部４４との隙間まで堆積した塵埃にも下向きに押し出す力を与えることができ、塵埃を多く吸引した場合でも容易に排出することができる。 The feature of the present embodiment is that the entire umbrella portion 44 slides. By sliding the umbrella part 44 as a whole, it is possible to give a force to push down the dust accumulated up to the gap between the outer cylinder 30 and the umbrella part 44, and even when a large amount of dust is sucked, it can be easily discharged. it can.
以上のようなごみ排出機構を集塵装置１０に設けることで、ごみ捨て時、集塵装置１０内の塵埃を容易に排出することができる。また、ごみ排出後、傘部４４と外筒３０との間への挟まりを大きく軽減できるため、ごみ捨て後に集塵装置１０内の残留したごみを使用者が取り除く等の手間を軽減でき、また、ごみに直接手で触れることを抑制できるため、使い勝手を大きく向上することができる。
（第三の実施形態）
次に、第三の実施形態について図面を参照しながら詳細に説明するが、掃除機本体１、及び集塵装置１０である外筒３０、内筒４０等の形状は第一の実施形態と基本的に同様である。本実施例は、第二の実施形態と同様に、傘部４４全体を摺動するごみ排出機構であり、以下では内筒４０の構造について説明する。
By providing the dust collecting mechanism 10 as described above, the dust in the dust collecting device 10 can be easily discharged when the dust is discarded. Moreover, since the pinching between the umbrella part 44 and the outer cylinder 30 can be greatly reduced after the waste is discharged, it is possible to reduce the trouble of the user removing the dust remaining in the dust collector 10 after throwing away the waste, Since it is possible to prevent direct contact with garbage, the usability can be greatly improved.
(Third embodiment)
Next, the third embodiment will be described in detail with reference to the drawings. The shapes of the vacuum cleaner main body 1 and the outer cylinder 30 and the inner cylinder 40 that are the dust collector 10 are the same as those of the first embodiment. The same. This example is a dust discharge mechanism that slides over the umbrella portion 44 as in the second embodiment, and the structure of the inner cylinder 40 will be described below.
図１６は、第三の実施形態における集塵装置１０の略中央の断面図を示した図である。第一の実施形態と摺動機構の構造は全く同じであるが、傘部４４の側面を覆うように内傘部４５を形成している。図に示すように、内傘部４５の底面に設けた鍔部４５ｃの外周に、更に円筒状の壁面４５ｄを設け、傘部４４を内傘部４５が覆った形状となっている。また、内傘部４５を傘部４４内に収納した状態で、壁面４５ｄの上端は傘部４４の上部に設けた鍔部４４ｃと接触し、傘部４４と内傘部４５との隙間を極力小さくすることで、傘部４４と内傘部４５との隙間に塵埃が入り込むのを防止している。 FIG. 16 is a cross-sectional view of the approximate center of the dust collector 10 in the third embodiment. The structure of the sliding mechanism is exactly the same as in the first embodiment, but the inner umbrella portion 45 is formed so as to cover the side surface of the umbrella portion 44. As shown in the drawing, a cylindrical wall surface 45 d is further provided on the outer periphery of the collar portion 45 c provided on the bottom surface of the inner umbrella portion 45, and the umbrella portion 44 is covered with the inner umbrella portion 45. Further, in the state where the inner umbrella portion 45 is housed in the umbrella portion 44, the upper end of the wall surface 45 d comes into contact with the collar portion 44 c provided on the upper portion of the umbrella portion 44, and the gap between the umbrella portion 44 and the inner umbrella portion 45 is as much as possible. By reducing the size, dust is prevented from entering the gap between the umbrella portion 44 and the inner umbrella portion 45.
本実施例の特徴は、第二の実施形態と同様に、傘部４４の側面が摺動することである。傘部４４の側面を摺動させることで、外筒３０と傘部４４との隙間まで堆積した塵埃にも下向きに押し出す力を与えることができ、塵埃を多く吸引した場合でも容易に排出することができる。 The feature of the present example is that the side surface of the umbrella portion 44 slides as in the second embodiment. By sliding the side surface of the umbrella part 44, it is possible to give a force to push down the dust accumulated up to the gap between the outer cylinder 30 and the umbrella part 44, and easily discharge even when a large amount of dust is sucked. Can do.
以上のようなごみ排出機構を集塵装置１０に設けることで、ごみ捨て時、集塵装置１０内の塵埃を容易に排出することができる。また、ごみ排出後、傘部４４と外筒３０との間への挟まりを大きく軽減できるため、ごみ捨て後に集塵装置１０内の残留したごみを使用者が取り除く等の手間を軽減でき、また、ごみに直接手で触れることを抑制できるため、使い勝手を大きく向上することができる。 By providing the dust collecting mechanism 10 as described above, the dust in the dust collecting device 10 can be easily discharged when the dust is discarded. Moreover, since the pinching between the umbrella part 44 and the outer cylinder 30 can be greatly reduced after the waste is discharged, it is possible to reduce the trouble of the user removing the dust remaining in the dust collector 10 after throwing away the waste, Since it is possible to prevent direct contact with garbage, the usability can be greatly improved.
なお、本発明に係る実施形態について適宜図面を参照して説明したが、本実施形態は上記の内容に限定されるものではなく、本発明の趣旨の範囲内において適宜変更して実施可能である。例えば、上記では、集塵装置１０に補塵フィルタ３２を備える電気掃除機１００を記載したが、ほ塵フィルタ３２を備えない電気掃除機でもよい。
