Description

本発明は、集塵容器に対しフィルタ組立体を着脱可能とした電気掃除機に関するものである。   The present invention relates to a vacuum cleaner in which a filter assembly is detachable from a dust collecting container.

従来、この種の電気掃除機としては、吸気ユニットを収容した本体ハウジングの前方に、吸込口を備えて内部に集塵室を形成する前側ハウジングを着脱可能に装着し、前記本体ハウジングに、前記吸気ユニットへの吸気口を塞いで前記前側ハウジング内へ突出するフィルタユニットを備えたクリーナが知られている（例えば特許文献１）。   Conventionally, as a vacuum cleaner of this type, a front housing that has a suction port and forms a dust collection chamber is detachably mounted in front of a main body housing that houses an air intake unit. There is known a cleaner including a filter unit that closes an intake port to the intake unit and protrudes into the front housing (for example, Patent Document 1).

また、前側ハウジングにフィルタユニットを着脱可能に装着し、前側ハウジングと共にフィルタユニットを着脱可能に構成した電気掃除機もある。このような電気掃除機は、前側ハウジングを外して内部の塵埃を捨てることができると共に、フィルタに付着した塵埃を捨てることができる。   There is also a vacuum cleaner in which a filter unit is detachably attached to the front housing, and the filter unit is detachably attached together with the front housing. In such a vacuum cleaner, the front housing can be removed and the internal dust can be discarded, and the dust attached to the filter can be discarded.

特開２０１０−２５９６６６号公報JP 2010-259666 A

上記のクリーナでは、前側ハウジング内の塵埃とフィルタユニットに付着した塵埃とを同時に捨てることができるという利便性を備えるが、前側ハウジングにフィルタを正しく装着しないと、気流漏れが発生して吸引された塵埃が吸気ユニットに達することで、塵埃を再び外気に撒き散らしたり、吸気ユニットの効率を低下させたりする虞がある。   The above cleaner has the convenience that the dust in the front housing and the dust attached to the filter unit can be discarded at the same time. When the dust reaches the intake unit, it may be scattered again to the outside air, or the efficiency of the intake unit may be reduced.

本発明は以上の問題点を解決し、集塵容器にフィルタ組立体を正しく取り付けた状態で、集塵容器を掃除機本体に取り付けることができる掃除機を提供することを目的とする。   This invention solves the above problem, and it aims at providing the cleaner which can attach a dust collecting container to a vacuum cleaner main body in the state which attached the filter assembly to the dust collecting container correctly.

本発明の請求項１に記載の電気掃除機は、掃除機本体と、この掃除機本体に対し着脱可能に取り付けられる集塵容器と、この集塵容器に対しバヨネット式に着脱されるフィルタ組立体とを有する電気掃除機において、前記集塵容器の開口縁部に第一切欠部を設け、前記フィルタ組立体の取付部の外周縁部に環状壁部を設け、この環状壁部に、前記第一切欠部に対応する第二切欠部を設けると共に、前記掃除機本体に、前記第一切欠部に対応する凸部を設けたものである。   The vacuum cleaner according to claim 1 of the present invention includes a vacuum cleaner main body, a dust collecting container that is detachably attached to the vacuum cleaner main body, and a filter assembly that is detachably attached to the dust collecting container in a bayonet manner. In the electric vacuum cleaner, the first edge portion is provided at the opening edge portion of the dust collecting container, the annular wall portion is provided at the outer peripheral edge portion of the attachment portion of the filter assembly, A second cutout portion corresponding to the first notch portion is provided, and a convex portion corresponding to the first notch portion is provided on the cleaner body.

また、本発明の請求項２に記載の電気掃除機は、請求項１において、前記第二切欠部の幅寸法と前記凸部の幅寸法とをほぼ等しく形成したものである。   Moreover, the vacuum cleaner of Claim 2 of this invention forms the width dimension of said 2nd notch part substantially equal to the width dimension of the said convex part in Claim 1.

更に、本発明の請求項３に記載の電気掃除機は、請求項１又は２において、前記凸部の幅方向端部に、前記第二切欠部の案内部を設けたものである。   Furthermore, the vacuum cleaner of Claim 3 of this invention provides the guide part of said 2nd notch part in the width direction edge part of the said convex part in Claim 1 or 2. In FIG.

本発明の請求項１に記載の電気掃除機は、以上のように構成することにより、前記集塵容器に前記フィルタ組立体を正しく取り付けると、前記集塵容器の第一切欠部と前記フィルタ組立体の第二切欠部とが位置合わせされ、この状態で前記集塵容器を前記掃除機本体に組み込むと、この掃除機本体の凸部に前記第一切欠部が係合する。一方、前記第一切欠部と第二切欠部とがずれた状態で前記集塵容器を前記掃除機本体に組み込もうとしても、前記掃除機本体の凸部に第一切欠部が係合しないことで、前記集塵容器を前記掃除機本体に組み込むことができないため、前記集塵容器とフィルタ組立体が正しく結合されていないことが分かる。   The vacuum cleaner according to claim 1 of the present invention is configured as described above, and when the filter assembly is correctly attached to the dust collection container, the first notch portion of the dust collection container and the filter When the dust collecting container is assembled in the cleaner body in this state, the second notch portion of the assembly is engaged with the convex portion of the cleaner body. On the other hand, even if the dust collecting container is to be assembled in the vacuum cleaner body with the first notch portion and the second notch portion being shifted, the first notch portion is engaged with the convex portion of the cleaner body. Since the dust collecting container cannot be incorporated into the cleaner body by not matching, it can be seen that the dust collecting container and the filter assembly are not properly coupled.

また、前記第二切欠部の幅寸法と前記凸部の幅寸法とをほぼ等しく形成したことで、フィルタ組立体を掃除機本体の正しい位置に配置することができる。   In addition, since the width dimension of the second notch part and the width dimension of the convex part are formed approximately equal, the filter assembly can be disposed at the correct position of the cleaner body.

更に、前記凸部の幅方向端部に、前記第二切欠部の案内部を設けたことで、前記第一切欠部と第二切欠部とが多少ずれていても、前記掃除機本体に前記集塵容器を組み込む際、前記凸部の案内部によって前記第二切欠部が案内されることで、前記フィルタ組立体が回転して、前記集塵容器に対し正しい位置に合わされる。これによって、前記集塵容器が前記掃除機本体に組み込むことができるようになる。   Further, by providing the guide portion of the second notch at the width direction end of the convex portion, even if the first notch and the second notch are slightly deviated from each other, When the dust collecting container is assembled, the filter assembly is rotated by being guided by the guide portion of the convex portion, and is adjusted to a correct position with respect to the dust collecting container. Accordingly, the dust collecting container can be incorporated into the cleaner body.

前記集塵容器３の周壁部１１における開口縁部３Ａ側の内周には、前記バヨネット用突起４２に対応して、バヨネット用溝４３が設けられている。このバヨネット用溝４３は、前記周壁部１１の開口縁部３Ａで開口する溝入口４３Ａと、この溝入口４３Ａに連通し前記周壁部１１の内周に沿って円周方向に延設される係止溝部４３Ｂとを有する。前記溝入口４３Ａは、係止溝部４３Ｂ側に前後方向の段部１４３を有すると共に、前後方向に対して反係止溝部４３Ｂ側に傾斜した傾斜段部１４３Ｋを有する。この傾斜段部１４３Ｋは、前記溝入口４３Ａが後方に向かって拡大するように傾斜し、前記バヨネット用突起４２を前記溝入口４３Ａの前側に案内する。   A bayonet groove 43 is provided on the inner periphery of the peripheral wall 11 of the dust collecting container 3 on the opening edge 3 </ b> A side corresponding to the bayonet protrusion 42. The bayonet groove 43 includes a groove inlet 43A that is opened at the opening edge 3A of the peripheral wall portion 11, and a member that communicates with the groove inlet 43A and extends in the circumferential direction along the inner periphery of the peripheral wall portion 11. And a stop groove portion 43B. The groove inlet 43A has a step portion 143 in the front-rear direction on the locking groove portion 43B side and an inclined step portion 143K inclined toward the anti-locking groove portion 43B side with respect to the front-rear direction. The inclined step portion 143K is inclined so that the groove inlet 43A expands rearward, and guides the bayonet protrusion 42 to the front side of the groove inlet 43A.

なお、前記段部１４３は集塵容器３の軸方向とほぼ平行に形成されている。また、上述したように、前記バヨネット用溝４３は、前記周壁部１１の内周に設けられているが、この周壁部１１が透光性を有する材料からなるから、一部、外側から見た図面でも、前記バヨネット用溝４３等を実線で図示している。   The step 143 is formed substantially parallel to the axial direction of the dust collecting container 3. Further, as described above, the bayonet groove 43 is provided on the inner periphery of the peripheral wall portion 11, but since the peripheral wall portion 11 is made of a light-transmitting material, a part thereof is viewed from the outside. In the drawing, the bayonet groove 43 and the like are shown by solid lines.

また、複数の前記係止溝部４３Ｂの少なくとも１つには、この係止溝部４３Ｂの先端側に突部４４が設けられている。なお、係止溝部４３Ｂの先端４３Ｓと前記突部４４との間隔は、前記バヨネット用突起４２の周方向の幅に対応している。また、前記周壁部１１の開口縁部３Ａ側の内周には、前記鍔部３４が当接する段部４５が形成されている。なお、前記段部４５は、前記周壁部１１の他部の内面より外周側に位置している。   Further, at least one of the plurality of locking groove portions 43B is provided with a protrusion 44 on the distal end side of the locking groove portion 43B. The interval between the tip 43S of the locking groove 43B and the protrusion 44 corresponds to the circumferential width of the bayonet protrusion 42. Further, a step portion 45 with which the flange portion 34 abuts is formed on the inner periphery of the peripheral wall portion 11 on the opening edge portion 3A side. The step 45 is located on the outer peripheral side from the inner surface of the other part of the peripheral wall 11.

Can be removed.

また、前記中央突条部７３は、１つの前記第一切欠部５１と前後方向に並んで位置している。そして、前記底面部６２には、前記掃除機本体２に前記集塵容器３を取り付けた際に、前記第一切欠部５１に対応する前記中央縦溝部７１の後方位置に、凸部８１が設けられている。この凸部８１は、前記装着部６１の外周部６６と前記吸込筒部６４とを連結するように形成されている。また、前記凸部８１は、前記横縁部５１Ｂ，５１Ｂ，５２Ｂ，５２Ｂ内に挿入する両側の側板部８２，８２と、両側の側板部８２，８２を連結する上面部８３とを備えている。また、この上面部８３の上部中央には、凸状の湾曲面部８３Ｗが形成されている。更に、前記凸部８１の幅方向端部には、前記側板部８２，８２と上面部８３の角部に湾曲面からなる案内部８１Ｋが形成されている。この案内部８１Ｋは、前記第二切欠部５２の面取り部５２Ｍに当接可能なものである。   Further, the central protrusion 73 is positioned side by side with the one first notch 51 in the front-rear direction. And, when the dust collecting container 3 is attached to the vacuum cleaner body 2, the bottom portion 62 has a convex portion 81 at a rear position of the central vertical groove portion 71 corresponding to the first notch 51. Is provided. The convex portion 81 is formed so as to connect the outer peripheral portion 66 of the mounting portion 61 and the suction cylinder portion 64. The convex portion 81 includes side plate portions 82 and 82 on both sides to be inserted into the lateral edge portions 51B, 51B, 52B and 52B, and an upper surface portion 83 for connecting the side plate portions 82 and 82 on both sides. . A convex curved surface portion 83 </ b> W is formed at the upper center of the upper surface portion 83. Furthermore, a guide portion 81K made of a curved surface is formed at the corners of the side plate portions 82 and 82 and the upper surface portion 83 at the end in the width direction of the convex portion 81. The guide portion 81K can come into contact with the chamfered portion 52M of the second cutout portion 52.

前記凸部８１は、前記底面部６２に膨出形成されており、前記凸部８１を利用して安全弁装置を構成している。具体的には、図２に示すように、前記凸部８１は弁ケース８４の一部を構成している。この弁ケース８４は、その外側の開閉口８５が前記掃除機本体２の外部に連通すると共に、内側に通気孔８６を設けている。また、この通気孔８６は、前記電動送風機５の吸込筒部６４の側面に連通している。そして、前記弁ケース８４内に前記開閉口８５を開閉する弁体８７を設けている。この弁体８７は、付勢手段（図示せず）により、前記開閉口８５に当接してこの開閉口８５を塞ぐ方向に付勢されている。   The convex portion 81 bulges on the bottom surface portion 62, and constitutes a safety valve device using the convex portion 81. Specifically, as shown in FIG. 2, the convex portion 81 constitutes a part of the valve case 84. The valve case 84 has an outer opening / closing port 85 communicating with the outside of the cleaner body 2 and a vent hole 86 provided on the inner side. Further, the vent hole 86 communicates with the side surface of the suction cylinder portion 64 of the electric blower 5. A valve body 87 for opening and closing the opening / closing port 85 is provided in the valve case 84. The valve body 87 is urged by an urging means (not shown) so as to abut against the opening / closing port 85 and close the opening / closing port 85.

そして、前記電動送風機５の駆動中に、前記ノズル１６等が詰まって前記吸込筒部６４から外気を吸引できなくなり、前記掃除機本体２のケース６内が所定値以下の負圧になると、前記弁体８７が図２中下方に移動して前記開閉口８５が開き、外気を導入する。このように動作することで、前記電動送風機５に負荷が掛かることを防止できる。なお、前記掃除機本体２のケース６の後部には、排気口８８が設けられている。   And while the electric blower 5 is being driven, the nozzle 16 and the like are clogged, and it becomes impossible to suck the outside air from the suction tube portion 64, and the inside of the case 6 of the cleaner body 2 becomes a negative pressure of a predetermined value or less. The valve body 87 moves downward in FIG. 2 and the opening / closing port 85 is opened to introduce outside air. By operating in this way, it is possible to prevent the electric blower 5 from being loaded. An exhaust port 88 is provided in the rear part of the case 6 of the cleaner body 2.

次に、前記掃除機１の使用方法につき、前記集塵容器３の着脱方法を中心に説明する。前記フィルタ組立体４を組み立てるには、前記内フィルタ体２２に前記筒状体２１を被せるようにして、前記バヨネット用突起２９を溝入口３７Ａに挿入し、前記筒状体２１を係止溝部３７Ｂの延設方向に回す。これにより、前記係止溝部３７Ｂに前記バヨネット用突起２９が係合して、前記筒状体２１に前記内フィルタ体２２が結合され、前記フィルタ組立体４が組み立てられる。   Next, how to use the vacuum cleaner 1 will be described focusing on how to attach and detach the dust collecting container 3. In order to assemble the filter assembly 4, the bayonet protrusion 29 is inserted into the groove inlet 37 </ b> A so as to cover the inner filter body 22 with the tubular body 21, and the tubular body 21 is inserted into the locking groove portion 37 </ b> B. Turn in the extending direction. As a result, the bayonet protrusion 29 engages with the locking groove 37B, the inner filter body 22 is coupled to the tubular body 21, and the filter assembly 4 is assembled.

次に、前記集塵容器３に前記フィルタ組立体４を取り付けるには、前記集塵容器３内に前記フィルタ組立体４を挿入し、前記段部４５に前記鍔部３４が当接するまで前記バヨネット用突起４２を前記溝入口４３Ａに挿入し、前記フィルタ組立体４を前記係止溝部４３Ｂの先端４３Ｓ側に回す。これにより、前記係止溝部４３Ｂに前記バヨネット用突起４２が係合して、前記集塵容器３に前記フィルタ組立体４が結合される。   Next, in order to attach the filter assembly 4 to the dust collection container 3, the filter assembly 4 is inserted into the dust collection container 3, and the bayonet is moved until the flange portion 34 comes into contact with the stepped portion 45. The projection 42 is inserted into the groove inlet 43A, and the filter assembly 4 is rotated toward the tip 43S of the locking groove 43B. As a result, the bayonet protrusion 42 is engaged with the locking groove 43B, and the filter assembly 4 is coupled to the dust collecting container 3.

このように、前記フィルタ組立体４を集塵容器３に正しく取り付け、前記集塵容器３を前記装着部６１に装着する場合は、前記掃除機本体２の縦溝部７１，７２Ｌ，７２Ｒに前記集塵容器３の突条部７３，７４Ｌ，７４Ｒを合わせて前記筒状部６３内に前記集塵容器３を前後方向に沿って挿入する。この際、前記中央縦溝部７１の係止部材７５の傾斜案内部７５Ａに、前記中央突条部７３の傾斜案内部７３Ａが当接し、前記中央突条部７３に押されて係止部材７５が非係止位置に移動し、前記傾斜案内部７３Ａが通過した後、前記係止部７５Ｂが係止受部７３Ｂと係合する。この位置で、前記第一及び第二切欠部５１，５２に前記凸部８１が入る。   As described above, when the filter assembly 4 is correctly attached to the dust collecting container 3 and the dust collecting container 3 is attached to the attachment portion 61, the dust collection container 3 is attached to the vertical groove portions 71, 72 </ b> L, 72 </ b> R of the cleaner body 2. The dust collecting container 3 is inserted along the front-rear direction into the cylindrical part 63 with the protrusions 73, 74L, 74R of the dust container 3 being aligned. At this time, the inclined guide portion 73A of the central ridge portion 73 abuts on the inclined guide portion 75A of the locking member 75 of the central longitudinal groove portion 71, and the locking member 75 is pushed by the central ridge portion 73. After moving to the non-locking position and passing through the inclined guide portion 73A, the locking portion 75B engages with the locking receiving portion 73B. At this position, the convex portion 81 enters the first and second cutout portions 51 and 52.

一方、前記集塵容器３とフィルタ組立体４とのバヨネット結合が不十分で、前記第一切欠部５１に前記後外筒部４１Ｓが重なり合っている場合は、前記係止部７５Ｂが前記係止受部７３Ｂに係合する前に、前記後外筒部４１Ｓが前記凸部８１に当接する。このため、前記係止受部７３Ｂに前記係止部７５Ｂが係合せず、前記装着部６１に前記集塵容器３を取り付けることができない。これにより、使用者は前記集塵容器３を取り外し、バヨネット結合を確認してから再度前記集塵容器３を取り付けることとになる。即ち、前記集塵容器３とフィルタ組立体４とを不完全な組み立て状態で、前記掃除機本体２に取り付けることを防止できる。   On the other hand, when the bayonet coupling between the dust collecting container 3 and the filter assembly 4 is insufficient and the rear outer cylinder portion 41S overlaps the first notch portion 51, the locking portion 75B is engaged with the engagement portion 75B. The rear outer cylinder portion 41S comes into contact with the convex portion 81 before engaging with the stopper portion 73B. For this reason, the locking portion 75B does not engage with the locking receiving portion 73B, and the dust collecting container 3 cannot be attached to the mounting portion 61. As a result, the user removes the dust collection container 3, confirms the bayonet connection, and then attaches the dust collection container 3 again. That is, it is possible to prevent the dust collecting container 3 and the filter assembly 4 from being attached to the cleaner body 2 in an incompletely assembled state.

また、図１３（Ａ）に示すように、前記第一切欠部５１に前記後外筒部４１Ｓが部分的に重なり合っている場合、前記後外筒部４１Ｓの面取り部５２Ｍが、前記凸部８１の案内部８１Ｋに当接すると、前記集塵容器３を押し込む力により、前記フィルタ組立体４が回転し、前記第一及び第二切欠部５１，５２が位置合わせされる。これによって、前記装着部６１に前記集塵容器３を組み込むことができる。   Further, as shown in FIG. 13 (A), when the rear outer cylinder part 41S partially overlaps the first notch 51, the chamfered part 52M of the rear outer cylinder part 41S has the convex part. When abutting against the guide portion 81K of 81, the filter assembly 4 is rotated by the force for pushing in the dust collecting container 3, and the first and second cutout portions 51 and 52 are aligned. As a result, the dust collecting container 3 can be incorporated into the mounting portion 61.

更に、万一、前記フィルタ組立体４を組み込まずに前記集塵容器３のみを前記装着部６１に装着した場合、前記集塵容器３の開口縁部３Ａに第一切欠部５１を設けたから、前記筒状部６３の内側と前記集塵容器３の外周との間の隙間を通って、前記第一切欠部５１，５１から前記集塵容器３内に空気が入り込む。このため、前記ノズル１６から塵埃を含む気流を吸い込まず、塵埃を再び外気に撒き散らしたり、前記電動送風機５の効率を低下させたりすることがない。   Furthermore, in the unlikely event that only the dust collecting container 3 is mounted on the mounting portion 61 without incorporating the filter assembly 4, the first notch 51 is provided at the opening edge 3 </ b> A of the dust collecting container 3. Through the gap between the inside of the cylindrical portion 63 and the outer periphery of the dust collecting container 3, air enters the dust collecting container 3 from the first notches 51 and 51. For this reason, the air current containing dust is not sucked from the nozzle 16, and the dust is not scattered again to the outside air, and the efficiency of the electric blower 5 is not reduced.

そして、前記装着部６１に前記集塵容器３を正しく装着した状態で、前記スイッチ操作部１０を操作して前記電動送風機５を駆動すると、前記ノズル１６から吸引された塵埃を含む空気が、前記集塵容器３の周方向に接続した接続筒部１５から前記集塵容器３に流れ込み、この集塵容器３内で渦流が形成され、この渦流に含まれる粗い塵埃が遠心分離され、前記周壁部１１と返し部２５との間から前記塵埃貯溜部２６に移動すると共に、砂等の粗くて重い塵埃が分離された気流は、前記小孔２３Ｈから前記筒状体２１内に流入する。なお、気流が前記返し部２５を乗り越える際に、この気流に含まれる塵埃の多くは、前記返し部２５によって下方に返されることになる。そして、気流に含まれる軽い塵埃は、前記筒状体２１内に流入する際に、一次フィルタとして作用する前記小孔２３Ｈ、或いは前記フィルタ本体３１によって捕捉される。このようにして、前記フィルタ本体３１によって細かい塵埃が分離された清浄な気流は、前記フィルタ６４Ｆを設けた吸込筒部６４を通過して、前記電動送風機５に至る。なお、前記吸込筒部６４から前記ケース６に吸い込まれた空気は、後部の前記排気口８８から排出される。   When the electric blower 5 is driven by operating the switch operation unit 10 in a state where the dust collecting container 3 is correctly mounted on the mounting unit 61, the air containing dust sucked from the nozzle 16 is From the connecting cylinder 15 connected in the circumferential direction of the dust collecting container 3, the dust flows into the dust collecting container 3, and a vortex is formed in the dust collecting container 3, and coarse dust contained in the vortex is centrifuged, and the peripheral wall 11 and the return part 25 move to the dust storage part 26, and airflow from which coarse and heavy dust such as sand is separated flows into the cylindrical body 21 from the small hole 23H. In addition, when an airflow gets over the said return part 25, much dust contained in this airflow is returned below by the said return part 25. FIG. Light dust contained in the airflow is captured by the small holes 23H acting as a primary filter or the filter main body 31 when flowing into the cylindrical body 21. Thus, the clean airflow from which fine dust has been separated by the filter body 31 passes through the suction cylinder portion 64 provided with the filter 64F and reaches the electric blower 5. The air sucked into the case 6 from the suction cylinder portion 64 is discharged from the exhaust port 88 at the rear portion.
