　そして、蓋体１０３を閉じた状態において、集塵容器１０１の集塵容器本体１０２を第１のパッキン１０７に当接することにより、集塵容器本体１０２とフィルターテクスチャー１０４との間の気密性を保持している。また、集塵容器１０１の蓋体１０３のフィルターテクスチャー１０４を第２のパッキン１０８に当接することにより、フィルターテクスチャー１０４とダストボックスカバー１０６との間の気密性を保持している。これにより、集塵容器本体１０２の後部の開口部を閉塞し、集塵容器１０１の気密性が保持されている。 Then, the airtightness between the dust collection container body 102 and the filter texture 104 is maintained by bringing the dust collection container body 102 of the dust collection container 101 into contact with the first packing 107 with the lid 103 closed. is doing. In addition, the filter texture 104 of the lid 103 of the dust collection container 101 is brought into contact with the second packing 108 to maintain the airtightness between the filter texture 104 and the dust box cover 106. Thereby, the opening part of the rear part of the dust container main body 102 is obstruct | occluded, and the airtightness of the dust container 101 is maintained.
　しかし、従来の電気掃除機の集塵容器１０１は、集塵容器１０１の気密性を保持するために、フィルターテクスチャー１０４の外周に設けられた第１のパッキン１０７と第２のパッキン１０８の２つのパッキンが必要である。そのため、集塵容器１０１の部品点数が増加し、集塵容器１０１の生産コストが増加するという問題があった。 However, in order to maintain the airtightness of the dust collection container 101, the dust collection container 101 of the conventional vacuum cleaner has two first packing 107 and second packing 108 provided on the outer periphery of the filter texture 104. Packing is necessary. Therefore, there is a problem that the number of parts of the dust collection container 101 increases and the production cost of the dust collection container 101 increases.

　以下に、本実施の形態の掃除機本体１の内部の構成について図３を用いて、詳細に説明する。 Hereinafter, the internal configuration of the cleaner body 1 of the present embodiment will be described in detail with reference to FIG.
　図３は、本発明の実施の形態１における集塵容器を備えた掃除機本体の断面図である。 FIG. 3 is a cross-sectional view of the main body of the cleaner provided with the dust collecting container in the first embodiment of the present invention.
　図３に示すように、掃除機本体１の後部には、吸引風を発生させる電動送風機１５を内蔵する電動送風機室１６が設けられている。そして、電動送風機１５の排気風は、電動送風機１５の排出口１５ａから電動送風機室１６を介して、掃除機本体１の後部の排気口１ｂから掃除機本体１の外部へ排気される。また、電動送風機１５は、本体下ケース８および本体上ケース９で保持された、前部に設けた第１モーターサポート１７と後部に設けた第２モーターサポート１８により、電動送風機室１６内に固定されている。 As shown in FIG. 3, an electric blower chamber 16 containing an electric blower 15 that generates suction air is provided at the rear of the cleaner body 1. The exhaust air of the electric blower 15 is exhausted from the exhaust port 1 b of the electric blower 15 through the electric blower chamber 16 to the outside of the vacuum cleaner main body 1 through the exhaust port 1 b at the rear of the cleaner main body 1. The electric blower 15 is fixed in the electric blower chamber 16 by a first motor support 17 provided at the front and a second motor support 18 provided at the rear, which are held by the main body lower case 8 and the main body upper case 9. Has been.
　また、掃除機本体１の前部には、電動送風機１５の吸引風で吸引された塵埃を捕集する集塵容器１９を着脱自在に収納する集塵室２０が設けられている。 In addition, a dust collection chamber 20 is provided at the front of the cleaner body 1 to detachably store a dust collection container 19 that collects dust sucked by the suction air of the electric blower 15.
　そして、集塵室２０と電動送風機室１６とは、本体下ケース８に設けられた隔壁１ｃによって分離されている。このとき、隔壁１ｃには、集塵室２０と電動送風機室１６とを連通する連通口（図示せず）が設けられている。また、隔壁１ｃに設けられた通気口（図示せず）の外周には、集塵容器１９の後部と隔壁１ｃとの間の気密性を保持するパッキン２１が設けられている。これにより、集塵容器１９から排出され、電動送風機室１６に至るまでの吸引風の通風路１ｄが集塵室２０と分離して形成されている。 The dust collection chamber 20 and the electric blower chamber 16 are separated by a partition wall 1c provided in the main body lower case 8. At this time, the partition wall 1c is provided with a communication port (not shown) that allows the dust collection chamber 20 and the electric blower chamber 16 to communicate with each other. In addition, a packing 21 is provided on the outer periphery of a vent (not shown) provided in the partition wall 1c to maintain the airtightness between the rear portion of the dust collecting container 19 and the partition wall 1c. Thus, a ventilation passage 1 d for suction air that is discharged from the dust collection container 19 and reaches the electric blower chamber 16 is formed separately from the dust collection chamber 20.
　また、本体蓋部１０の内側には、集塵容器１９内の塵埃の廃棄時期を使用者に報知する集塵量表示装置２２が、例えばネジなどで取り付けられている。集塵量表示装置２２は、例えばプラスチックなどの透明材料で形成され、指針筒本体２３と指針弁２４とを有する指針筒２５と、指針２６と、指針バネ２７と、から構成されている。指針筒本体２３は、一端に集塵室２０と連通する連通口２３ａを有し、他端に指針弁２４が設けられている。指針筒本体２３内には、電動送風機１５の吸引により発生する負圧と、大気圧との差圧で変位する指針２６と、指針２６を指針筒２５の大気圧側に付勢する指針バネ２７とが設けられている。そして、指針弁２４には、通風路１ｄと指針筒本体２３の内部とを連通する連通通路２４ａが形成されている。 Also, a dust collection amount display device 22 for notifying the user of the disposal time of the dust in the dust collection container 19 is attached to the inside of the main body lid portion 10 with, for example, a screw. The dust collection amount display device 22 is formed of a transparent material such as plastic, for example, and includes a pointer cylinder 25 having a pointer cylinder body 23 and a pointer valve 24, a pointer 26, and a pointer spring 27. The pointer cylinder body 23 has a communication port 23a that communicates with the dust collection chamber 20 at one end, and a pointer valve 24 is provided at the other end. In the pointer cylinder main body 23, a pointer 26 that is displaced by a differential pressure between the negative pressure generated by the suction of the electric blower 15 and the atmospheric pressure, and a pointer spring 27 that urges the pointer 26 toward the atmospheric pressure side of the pointer cylinder 25. And are provided. The pointer valve 24 is formed with a communication passage 24 a that communicates the ventilation path 1 d and the inside of the pointer cylinder body 23.
　また、指針筒本体２３の上部には、掃除機１００の動作時に指針２６の動作を視認する窓部２８が設けられている。そして、本体上ケース９の本体蓋部１０には、指針２６の窓部２８と対応する位置に、窓穴部２９が設けられ、使用者が指針２６の動作を視認できるように構成されている。 Further, a window portion 28 for visually recognizing the operation of the pointer 26 when the cleaner 100 is operated is provided on the upper portion of the pointer cylinder main body 23. The main body lid portion 10 of the main body upper case 9 is provided with a window hole portion 29 at a position corresponding to the window portion 28 of the pointer 26 so that the user can visually recognize the operation of the pointer 26. .
　ここで、使用者に集塵容器１９内の塵埃を廃棄する時期を報知する集塵量表示装置２２の報知方法について、図３を参照しながら以下で説明する。 Here, a notification method of the dust collection amount display device 22 for notifying the user of the timing for discarding the dust in the dust collection container 19 will be described below with reference to FIG.
　まず、電動送風機１５の運転を開始すると、電動送風機１５によって吸引風が発生する。これにより、集塵量表示装置２２の連通口２３ａ側に大気圧がかかり、集塵量表示装置２２の指針弁２４側に負圧がかかる。このとき、集塵容器１９内に堆積した塵埃の量が増大し一定量以上になると、集塵量表示装置２２の指針弁２４側にかかる負圧と、集塵量表示装置２２の連通口２３ａ側にかかる大気圧との差圧が指針バネ２７の付勢力より大きくなる。すると、指針２６が指針弁２４側へと移動し、窓部２８の位置で停止する。これより、集塵量表示装置２２は、集塵容器１９内の塵埃を廃棄する時期を使用者に報知する。 First, when the operation of the electric blower 15 is started, suction wind is generated by the electric blower 15. Thereby, atmospheric pressure is applied to the communication port 23 a side of the dust collection amount display device 22, and negative pressure is applied to the pointer valve 24 side of the dust collection amount display device 22. At this time, when the amount of dust accumulated in the dust collection container 19 increases to a certain level or more, the negative pressure applied to the pointer valve 24 side of the dust collection amount display device 22 and the communication port 23a of the dust collection amount display device 22 are displayed. The differential pressure from the atmospheric pressure applied to the side becomes larger than the urging force of the pointer spring 27. Then, the pointer 26 moves to the pointer valve 24 side and stops at the position of the window portion 28. Thus, the dust collection amount display device 22 notifies the user of the timing for discarding the dust in the dust collection container 19.
　以下に、本実施の形態の集塵容器１９の構成について、図４～図８を用いて詳細に説明する。 Hereinafter, the configuration of the dust collecting container 19 of the present embodiment will be described in detail with reference to FIGS.

FIG. 6 is an enlarged cross-sectional view of a main part of the dust collection container in the first embodiment of the present invention. FIG. 7 is an enlarged cross-sectional view of a main part showing another form of the dust collecting container according to Embodiment 1 of the present invention. FIG. 8 is a cross-sectional view of the lid and filter part of the dust collecting container in the first embodiment of the present invention.
　図４および図５に示すように、集塵容器１９は、流入口３０ａと開口部３０ｂとを有する集塵容器本体３０と、開口部３０ｂを開閉自在に覆う蓋体３１と、蓋体３１を備えたフィルター部３２と、から構成されている。 4 and 5, the dust collection container 19 includes a dust collection container body 30 having an inlet 30a and an opening 30b, a lid 31 that covers the opening 30b so as to be opened and closed, and a lid 31. And a filter part 32 provided.
　集塵容器本体３０の側面には、ブラシ体５０を有する掃除用ブラシ４４が着脱自在に取り付けられている。掃除用ブラシ４４は、ブラシ体５０を用いて一次フィルター部３５および二次フィルター部３６に付着した塵埃を除去する。 A cleaning brush 44 having a brush body 50 is detachably attached to the side surface of the dust collecting container body 30. The cleaning brush 44 uses the brush body 50 to remove dust attached to the primary filter portion 35 and the secondary filter portion 36.
　また、集塵容器本体３０の下面の後部に設けられた第１の軸受け部３３は、蓋体３１の下面に設けられた第１の軸部３４を回動自在に支持している。これにより、蓋体３１が、集塵容器本体３０に回動自在に取り付けられる。 Further, the first bearing portion 33 provided at the rear portion of the lower surface of the dust container main body 30 supports the first shaft portion 34 provided at the lower surface of the lid 31 so as to be rotatable. Thereby, the cover body 31 is rotatably attached to the dust container main body 30.
　集塵容器本体３０の前部には、塵埃が流入する流入口３０ａが図３に示す掃除機本体１の吸引口１ａと連通して設けられている。 In the front part of the dust collecting container body 30, an inlet 30a through which dust flows is provided in communication with the suction port 1a of the cleaner body 1 shown in FIG.
　集塵容器本体３０の後部（集塵容器本体３０の下流側）には、開閉自在な蓋体３１により覆われた開口部３０ｂが設けられている。蓋体３１の上流側（蓋体３１の集塵容器本体３０側）には、蓋体３１に、例えばネジなどの固定部材で取り付けられている塵埃を捕集するフィルター部３２が配置されている。 In the rear part of the dust container main body 30 (downstream of the dust container main body 30), an opening 30b covered with an openable / closable lid 31 is provided. On the upstream side of the lid body 31 (on the dust collection container body 30 side of the lid body 31), a filter unit 32 that collects dust attached to the lid body 31 with a fixing member such as a screw is disposed. .
　フィルター部３２は、粗塵を捕集する一次フィルター部３５と、細塵を捕集する二次フィルター部３６と、から構成されている。二次フィルター部３６は、一次フィルター部３５の下流側、すなわち、一次フィルター部３５の蓋体３１側に配置されている。 The filter unit 32 includes a primary filter unit 35 that collects coarse dust and a secondary filter unit 36 that collects fine dust. The secondary filter portion 36 is disposed on the downstream side of the primary filter portion 35, that is, on the lid body 31 side of the primary filter portion 35.
　そして、一次フィルター部３５は、二次フィルター部３６の外周を覆うように配置されている。ここで、図８に示すように、一次フィルター部３５は、例えばメッシュ状もしくは多孔質状に形成された、一次フィルター３７と、一次フィルター３７を保持する一次フィルター枠体３８と、から構成されている。 And the primary filter part 35 is arrange | positioned so that the outer periphery of the secondary filter part 36 may be covered. Here, as shown in FIG. 8, the primary filter portion 35 is composed of, for example, a primary filter 37 formed in a mesh shape or a porous shape, and a primary filter frame body 38 that holds the primary filter 37. Yes.
　また、二次フィルター部３６は、例えばプリーツ加工された、二次フィルター３９と、二次フィルター３９を保持する二次フィルター枠体４０と、から構成されている。 Further, the secondary filter unit 36 includes, for example, a pleated secondary filter 39 and a secondary filter frame body 40 that holds the secondary filter 39.
　これにより、粗塵によって二次フィルター部３６の目詰まりを十分に防止できる。その結果、フィルター部３２でより多くの塵埃を確実に捕集して、集塵容器１９の集塵性能を向上できる。 This can sufficiently prevent clogging of the secondary filter portion 36 due to coarse dust. As a result, more dust can be reliably collected by the filter unit 32 and the dust collection performance of the dust collection container 19 can be improved.
　図５～図８に示すように、例えば断面形状が四角形の棒状の軟質材で形成されたシール部材４１は蓋体３１に設けられ、蓋体３１とフィルター部３２との間、すなわち、蓋体３１と二次フィルター部３６の二次フィルター枠体４０との間に配置されている。このとき、シール部材４１は、少なくともフィルター部３２と集塵容器本体３０とに当接して密閉しており、蓋体３１とフィルター部３２との間の気密性および集塵容器本体３０と蓋体３１との間の気密性を保持する。なお、軟質材としては、例えばゴムやエラストマーが好ましいが、当接リブ４２およびタイトリブ４３がシール部材４１に食い込む程度の硬さで、かつ、集塵容器１９の気密性が保持できる材質であれば特に限定しない。 As shown in FIG. 5 to FIG. 8, for example, a sealing member 41 formed of a rod-like soft material having a square cross-sectional shape is provided on the lid 31 and is provided between the lid 31 and the filter portion 32, that is, the lid. 31 and the secondary filter frame 40 of the secondary filter section 36. At this time, the seal member 41 is sealed in contact with at least the filter portion 32 and the dust collection container body 30, and the airtightness between the lid body 31 and the filter section 32 and the dust collection container body 30 and the lid body are sealed. The airtightness between 31 is maintained. As the soft material, for example, rubber or elastomer is preferable. However, any material can be used as long as the contact rib 42 and the tight rib 43 are hard enough to bite into the seal member 41 and the airtightness of the dust collecting container 19 can be maintained. There is no particular limitation.
　以上により、蓋体３１とフィルター部３２との間に配置されたシール部材４１のみで集塵容器１９の気密性を確実に保持することができるとともに、集塵容器１９の部品点数を削減することができる。その結果、集塵容器１９の生産コストを低減することができる。 As described above, the airtightness of the dust collecting container 19 can be reliably maintained only by the seal member 41 disposed between the lid 31 and the filter portion 32, and the number of parts of the dust collecting container 19 can be reduced. Can do. As a result, the production cost of the dust collecting container 19 can be reduced.
　図５および図６に示すように、二次フィルター部３６のシール部材４１と当接する位置の二次フィルター枠体４０には、シール部材４１側に向かって突出する当接リブ４２が設けられている。 As shown in FIGS. 5 and 6, the secondary filter frame body 40 at a position where it comes into contact with the seal member 41 of the secondary filter portion 36 is provided with a contact rib 42 protruding toward the seal member 41 side. Yes.
　これにより、フィルター部３２に当接リブ４２を設けていない場合に比べ、当接リブ４２をシール部材４１に食い込ませてより確実に集塵容器本体３０とフィルター部３２とを密閉することができる。その結果、フィルター部３２とシール部材４１との間から塵埃が漏れることを十分に防止して、集塵容器１９の信頼性を向上させることができる。 Thereby, compared with the case where the contact rib 42 is not provided in the filter part 32, the dust collection container main body 30 and the filter part 32 can be sealed more reliably by biting the contact rib 42 into the seal member 41. . As a result, it is possible to sufficiently prevent the dust from leaking between the filter portion 32 and the seal member 41 and to improve the reliability of the dust collecting container 19.
　また、シール部材４１と当接する位置の集塵容器本体３０には、蓋体３１側に向かって突出するタイトリブ４３が設けられている。タイトリブ４３は、当接リブ４２より集塵容器本体３０の外周側に配置されている。 Also, the dust collecting container main body 30 at a position in contact with the seal member 41 is provided with a tight rib 43 protruding toward the lid 31 side. The tight rib 43 is disposed on the outer peripheral side of the dust collecting container main body 30 with respect to the contact rib 42.
　このとき、掃除機本体１に集塵容器１９が取り付けられた状態で電動送風機１５によって吸引風が発生されると、電動送風機１５で発生された吸引風によって集塵容器１９の内部が負圧となり、集塵容器本体３０が蓋体３１側へと移動する。このため、集塵容器本体３０に設けられたタイトリブ４３がシール部材４１側へと移動し、タイトリブ４３とシール部材４１とが圧接される（図６の矢印Ａ参照）。電気掃除機１００を運転している状態における集塵容器本体３０のタイトリブ４３がシール部材４１に食い込む面積は、電気掃除機１００を運転していない状態における集塵容器本体３０のタイトリブ４３がシール部材４１に食い込む面積よりも大きくなる。 At this time, when suction air is generated by the electric blower 15 in a state where the dust collection container 19 is attached to the cleaner body 1, the inside of the dust collection container 19 becomes negative pressure due to the suction air generated by the electric blower 15. The dust container main body 30 moves to the lid body 31 side. For this reason, the tight rib 43 provided in the dust container main body 30 moves to the seal member 41 side, and the tight rib 43 and the seal member 41 are pressed against each other (see arrow A in FIG. 6). The area in which the tight rib 43 of the dust collecting container body 30 in the state where the vacuum cleaner 100 is operating bites into the seal member 41 is the tight rib 43 of the dust collecting container body 30 in the state where the vacuum cleaner 100 is not operating. It becomes larger than the area which bites into 41.
　これにより、蓋体３１によって集塵容器本体３０の後部に設けられた開口部３０ｂが閉塞された状態において、タイトリブ４３をシール部材４１に食い込ませて、集塵容器本体３０とシール部材４１との密着性を向上させる。その結果、集塵容器本体３０とシール部材４１との間から塵埃の漏れを十分に防止して、集塵容器１９の信頼性をさらに向上させることができる。 Thereby, in a state where the opening 30b provided in the rear portion of the dust collection container main body 30 is closed by the lid 31, the tight rib 43 is bitten into the seal member 41, and the dust collection container main body 30 and the seal member 41 are Improve adhesion. As a result, it is possible to sufficiently prevent dust from leaking between the dust container main body 30 and the seal member 41 and further improve the reliability of the dust container 19.
　なお、フィルター部３２に設けた当接リブ４２と集塵容器本体３０のタイトリブ４３とは必ずしもシール部材４１に食い込ませる必要はなく、当接しているだけでもよい。この場合は、当接リブ４２およびタイトリブ４３とシール部材４１との接触面積を通常よりも大きくすれば、上記と同様の効果が得られる。 Note that the abutment ribs 42 provided on the filter portion 32 and the tight ribs 43 of the dust collecting container body 30 do not necessarily have to bite into the seal member 41, and may only abut. In this case, if the contact area between the contact rib 42 and the tight rib 43 and the seal member 41 is made larger than usual, the same effect as described above can be obtained.
　また、図７に示すように、電気掃除機１００の運転を開始していない、かつ、蓋体３１がシール部材４１と当接した状態において、集塵容器本体３０と蓋体３１との間には、隙間Ｔが形成されるように構成してもよい。なお、隙間Ｔは、例えば０．１～１ｍｍ程度であればよく、特に、例えば０．２～０．５ｍｍ程度が好ましいが、特に限定はしない。 In addition, as shown in FIG. 7, when the operation of the vacuum cleaner 100 is not started and the cover 31 is in contact with the seal member 41, the dust container main body 30 and the cover 31 are interposed. May be configured such that a gap T is formed. The gap T may be about 0.1 to 1 mm, for example, and is particularly preferably about 0.2 to 0.5 mm, but is not particularly limited.
　これにより、掃除機本体１に集塵容器１９を取り付けて電気掃除機１００の運転を開始した際において、集塵容器本体３０とシール部材４１との圧接量を増加させ、集塵容器本体３０とシール部材４１との密着性を向上させることができる。その結果、集塵容器本体３０と蓋体３１との間から塵埃が漏れることを十分に防止することができ、集塵容器本体３０とシール部材４１との間の気密性を確実に保持することができるとともに、集塵容器１９の信頼性を向上させることができる。 Thus, when the dust collecting container 19 is attached to the cleaner body 1 and the operation of the vacuum cleaner 100 is started, the amount of pressure contact between the dust collecting container body 30 and the seal member 41 is increased. Adhesion with the seal member 41 can be improved. As a result, it is possible to sufficiently prevent the dust from leaking between the dust container main body 30 and the lid 31, and to reliably maintain the airtightness between the dust container main body 30 and the seal member 41. And the reliability of the dust collecting container 19 can be improved.
　以上のように構成された集塵容器１９を有する電気掃除機１００の動作および作用について、図１、図３および図５を参照しながら以下に説明する。 The operation and action of the vacuum cleaner 100 having the dust collecting container 19 configured as described above will be described below with reference to FIGS. 1, 3, and 5.
　図１および図２に示すように、電気掃除機１００の運転を開始すると、電動送風機１５によって吸引風が発生する。この吸引風により、床などの被清掃面の塵埃が、吸込具２、延長管３、ホース４、および吸引口１ａを介して掃除機本体１内へ吸い込まれる。そして、掃除機本体１に吸い込まれた塵埃は、図５に示すように集塵容器１９の流入口３０ａから集塵容器１９の内部へ流入する。流入した塵埃は、フィルター部３２を通過する際に、まず、一次フィルター部３５で塵埃の粗塵が捕集され、二次フィルター部３６で塵埃の細塵が捕集される。その後、図３に示すように、塵埃が捕集された吸引風の空気のみが集塵容器１９の後部に設けられた通風路１ｄを介して電動送風機１５内へと流入する。電動送風機１５内へと流入した空気は、電動送風機１５の排出口１５ａから電動送風機室１６内へと排出される。排出された空気は、掃除機本体１の後部に設けられた排気口１ｂから掃除機本体１の外部に排出される。これにより、被清掃面の掃除を行うことができる。 As shown in FIGS. 1 and 2, when the operation of the vacuum cleaner 100 is started, suction air is generated by the electric blower 15. Dust on the surface to be cleaned such as the floor is sucked into the cleaner main body 1 through the suction tool 2, the extension pipe 3, the hose 4, and the suction port 1a by the suction air. The dust sucked into the cleaner body 1 flows into the dust collecting container 19 from the inlet 30a of the dust collecting container 19 as shown in FIG. When the inflowing dust passes through the filter unit 32, first, coarse dust of dust is collected by the primary filter unit 35, and fine dust of dust is collected by the secondary filter unit 36. Thereafter, as shown in FIG. 3, only the air of the suction air in which the dust is collected flows into the electric blower 15 through the ventilation path 1 d provided at the rear portion of the dust collection container 19. The air that has flowed into the electric blower 15 is discharged from the discharge port 15 a of the electric blower 15 into the electric blower chamber 16. The discharged air is discharged to the outside of the cleaner body 1 through an exhaust port 1b provided at the rear portion of the cleaner body 1. Thereby, the surface to be cleaned can be cleaned.
　そして、集塵容器１９内に堆積した塵埃の量が増加して、一定量以上になると、集塵量表示装置２２により集塵容器１９内の塵埃の廃棄時期が以下の方法により報知される。 When the amount of dust accumulated in the dust collection container 19 increases and exceeds a certain amount, the dust collection time display device 22 notifies the dust disposal timing of the dust collection container 19 by the following method.
　つまり、上述したように、本体蓋部１０に設けられた集塵量表示装置２２の指針弁２４側にかかる負圧と集塵量表示装置２２の連通口２３ａ側にかかる大気圧との圧力の差が指針バネ２７の付勢力より大きくなる。そのため、集塵量表示装置２２の指針２６が指針弁２４側へと移動し、窓部２８の位置で停止することにより、報知される。 That is, as described above, the pressure between the negative pressure applied to the pointer valve 24 side of the dust collection amount display device 22 provided in the main body lid 10 and the atmospheric pressure applied to the communication port 23a side of the dust collection amount display device 22. The difference becomes larger than the urging force of the pointer spring 27. Therefore, the notification is made when the pointer 26 of the dust collection amount display device 22 moves toward the pointer valve 24 and stops at the position of the window portion 28.
　このとき、使用者は、指針２６の位置を本体蓋部１０の窓穴部２９から集塵量表示装置２２の窓部２８を目視し、針２６の下方にある場合、集塵容器１９内の塵埃の廃棄時期であると判断する。そして、使用者は、本体上ケース９の本体蓋部１０を取っ手部１０ａにより開けて、集塵容器１９を掃除機本体１から取り外し、集塵容器１９内に蓄積された塵埃を廃棄する。 At this time, the user visually observes the window portion 28 of the dust collection amount display device 22 from the window hole portion 29 of the main body lid portion 10 in the position of the pointer 26, and when it is below the needle 26, Judge that it is time to dispose of dust. Then, the user opens the main body lid portion 10 of the main body upper case 9 with the handle portion 10a, removes the dust collecting container 19 from the cleaner body 1, and discards the dust accumulated in the dust collecting container 19.
　ここで、掃除機本体１に集塵容器１９が取り付けられた状態で電動送風機１５によって吸引風が発生されると、電動送風機１５で発生された吸引風によって集塵容器１９の内部が負圧となる。このため、集塵容器本体３０と蓋体３１との隙間、および、蓋体３１とフィルター部３２との隙間から集塵容器１９の内部へと外気が吸引される。集塵容器本体３０と蓋体３１との隙間、および、蓋体３１とフィルター部３２との隙間から集塵容器１９の内部へと外気が流入してしまうと、電動送風機１５の吸引風による吸引力が低下する。その結果、電気掃除機１００は、被清掃面の塵埃を吸込具２で効率よく吸引できなくなる場合がある。 Here, when suction air is generated by the electric blower 15 in a state where the dust collection container 19 is attached to the cleaner body 1, the inside of the dust collection container 19 becomes negative pressure by the suction air generated by the electric blower 15. Become. For this reason, outside air is sucked into the inside of the dust collecting container 19 from the gap between the dust collecting container body 30 and the lid 31 and the gap between the lid 31 and the filter part 32. If outside air flows into the dust collecting container 19 from the gap between the dust collecting container body 30 and the lid 31 and the gap between the lid 31 and the filter portion 32, suction by the electric blower 15 by suction air is performed. Power is reduced. As a result, the vacuum cleaner 100 may not be able to efficiently suck the dust on the surface to be cleaned with the suction tool 2.
　本実施の形態によれば、蓋体３１とフィルター部３２との間に設けられたシール部材４１にフィルター部３２および集塵容器本体３０を当接した構成を有する。そのため、集塵容器本体３０と蓋体３１との間、および、蓋体３１とフィルター部３２との間から集塵容器１９の内部へ外気が流入することを確実に防止できる。その結果、集塵容器本体３０と蓋体３１との間、および、蓋体３１とフィルター部３２との間の気密性を確実に保持することができる。 According to the present embodiment, the filter unit 32 and the dust container main body 30 are in contact with the seal member 41 provided between the lid 31 and the filter unit 32. Therefore, it is possible to reliably prevent outside air from flowing into the dust container 19 between the dust container main body 30 and the lid 31 and between the lid 31 and the filter portion 32. As a result, airtightness between the dust container main body 30 and the lid 31 and between the lid 31 and the filter portion 32 can be reliably maintained.
　（実施の形態２）
　本発明の実施の形態２の集塵容器について、図９および図１０を用いて以下に説明する。 (Embodiment 2)
The dust container according to Embodiment 2 of the present invention will be described below with reference to FIGS. 9 and 10.
　図９は、本発明の実施の形態２における集塵容器の蓋体およびフィルター部の要部拡大断面図である。 FIG. 9 is an enlarged cross-sectional view of the main part of the lid and the filter part of the dust collecting container in the second embodiment of the present invention.
　本実施の形態は、集塵容器１９の一次フィルター部３５に嵌合凹部４５を設け、二次フィルター部３６に嵌合凹部４５と嵌合する嵌合凸部４６を設けた点で実施の形態１とは異なる。 This embodiment is an embodiment in that a fitting concave portion 45 is provided in the primary filter portion 35 of the dust collecting container 19 and a fitting convex portion 46 that is fitted to the fitting concave portion 45 is provided in the secondary filter portion 36. Different from 1.
　つまり、図９に示すように、一次フィルター部３５の一次フィルター枠体３８の内側に嵌合凹部４５を設け、二次フィルター部３６の二次フィルター枠体４０の嵌合凹部４５に対応する位置に、嵌合凸部４６が設けられている。そして、一次フィルター部３５が二次フィルター部３６に取り付けられた際に、一次フィルター部３５の嵌合凹部４５と嵌合する二次フィルター部３６の嵌合凸部４６が嵌合する。これにより、一次フィルター部３５は、二次フィルター部３６に保持される。 That is, as shown in FIG. 9, the fitting recess 45 is provided inside the primary filter frame 38 of the primary filter portion 35, and the position corresponding to the fitting recess 45 of the secondary filter frame 40 of the secondary filter portion 36. In addition, a fitting convex portion 46 is provided. And when the primary filter part 35 is attached to the secondary filter part 36, the fitting convex part 46 of the secondary filter part 36 fitted with the fitting recessed part 45 of the primary filter part 35 fits. As a result, the primary filter unit 35 is held by the secondary filter unit 36.
　以上のように構成された集塵容器１９内に堆積した塵埃を廃棄する動作について、図１０を参照しながら以下に説明する。 The operation of discarding the dust accumulated in the dust collecting container 19 configured as described above will be described below with reference to FIG.
　図１０は、本発明の実施の形態２における集塵容器のゴミ捨て操作を示す斜視図である。 FIG. 10 is a perspective view showing a dust disposal operation of the dust collecting container in the second embodiment of the present invention.
　図１０に示すように、集塵容器１９内に堆積した塵埃を廃棄する場合、まず、集塵容器１９に回動自在に設けられた蓋体３１を回動させ、集塵容器本体３０の後部に設けられた開口部３０ｂを開放する。そして、開口部３０ｂが下方を向くように集塵容器１９を保持し、集塵容器１９内に堆積した塵埃を開口部３０ｂから集塵容器１９の外部へと排出する。このとき、集塵容器本体３０の開口部３０ｂが下方に向くように集塵容器１９を保持すると、一次フィルター部３５および二次フィルター部３６の上流側も下方を向くように保持される。そのため、一次フィルター部３５が二次フィルター部３６に保持されていない場合、一次フィルター部３５が自重により二次フィルター部３６から外れる場合があった。 As shown in FIG. 10, when discarding the dust accumulated in the dust collecting container 19, first, the lid 31 provided rotatably on the dust collecting container 19 is rotated, and the rear part of the dust collecting container main body 30 is rotated. The opening 30b provided in is opened. Then, the dust collection container 19 is held so that the opening 30 b faces downward, and the dust accumulated in the dust collection container 19 is discharged from the opening 30 b to the outside of the dust collection container 19. At this time, when the dust collection container 19 is held such that the opening 30b of the dust collection container body 30 faces downward, the upstream side of the primary filter part 35 and the secondary filter part 36 is also held downward. Therefore, when the primary filter part 35 is not held by the secondary filter part 36, the primary filter part 35 may be detached from the secondary filter part 36 due to its own weight.
　そこで、本実施の形態は、一次フィルター枠体３８に設けた嵌合凹部４５を二次フィルター枠体４０に設けられた嵌合凸部４６に嵌合させて、一次フィルター部３５を二次フィルター部３６で保持する構成としている。これにより、ゴミ捨て時に、一次フィルター部３５を二次フィルター部３６に確実に保持させて、一次フィルター部３５が二次フィルター部３６から外れることを防止できる。その結果、ゴミ捨て時の作業性や操作性などの集塵容器１９の使い勝手を向上させることができる。 Accordingly, in the present embodiment, the fitting concave portion 45 provided in the primary filter frame body 38 is fitted into the fitting convex portion 46 provided in the secondary filter frame body 40 so that the primary filter portion 35 is made into the secondary filter. It is configured to be held by the part 36. Thereby, the primary filter part 35 can be reliably held by the secondary filter part 36 when the dust is thrown away, and the primary filter part 35 can be prevented from being detached from the secondary filter part 36. As a result, it is possible to improve the usability of the dust collection container 19 such as workability and operability when throwing away the garbage.
　なお、本実施の形態では、一次フィルター枠体３８に嵌合凹部４５を設け、二次フィルター枠体４０に嵌合凸部４６に設けた構成を例に説明したが、これに限られない。一次フィルター部３５を二次フィルター部３６に保持することができる構成であればよい。例えば一次フィルター枠体３８に嵌合凸部を設け、二次フィルター枠体４０に嵌合凹部を設けてもよい。これにより、同様の効果を得ることができる。 In the present embodiment, the configuration in which the fitting concave portion 45 is provided in the primary filter frame 38 and the fitting convex portion 46 is provided in the secondary filter frame 40 has been described as an example, but the present invention is not limited thereto. Any structure that can hold the primary filter unit 35 in the secondary filter unit 36 may be used. For example, the primary filter frame body 38 may be provided with a fitting convex portion, and the secondary filter frame body 40 may be provided with a fitting concave portion. Thereby, the same effect can be acquired.
　また、本実施の形態では、嵌合凹部４５が、半円形状の凹部で、嵌合凸部４６が、半円形状の凸部を例に説明したが、これに限らない。例えば、嵌合凹部４５および嵌合凸部４６の断面形状は、四角形や三角形などでもよく、嵌合できる形状であれば任意である。これにより、同様の効果を得ることができる。 In the present embodiment, the fitting concave portion 45 is a semicircular concave portion and the fitting convex portion 46 is a semicircular convex portion, but the present invention is not limited thereto. For example, the cross-sectional shapes of the fitting concave portion 45 and the fitting convex portion 46 may be quadrangular or triangular, and are arbitrary as long as they can be fitted. Thereby, the same effect can be acquired.
　また、本実施の形態では、嵌合凹部４５および嵌合凸部４６を一対とした例で説明したが、これに限らない。例えば、一次フィルター部３５および二次フィルター部３６の全周に複数個設けてもよく、２対以上で凹部および凸部の組み合わせは任意である。これにより、一次フィルター部３５は、二次フィルター部３６により強固に保持される。 In the present embodiment, the fitting recess 45 and the fitting protrusion 46 are described as an example, but the present invention is not limited to this. For example, a plurality of primary filter portions 35 and secondary filter portions 36 may be provided on the entire circumference, and the combination of the concave and convex portions is arbitrary in two or more pairs. Thereby, the primary filter part 35 is firmly held by the secondary filter part 36.
　（実施の形態３）
　本発明の実施の形態３の集塵容器について、図１１～図１３を用いて説明する。 (Embodiment 3)
A dust container according to Embodiment 3 of the present invention will be described with reference to FIGS.
　図１１は、本発明の実施の形態３における集塵容器のフィルター部の掃除時の断面図である。図１２は、本発明の実施の形態３における集塵容器のフィルター部の掃除時の要部拡大断面図である。図１３は、本発明の実施の形態３における集塵容器のフィルター部の掃除時の斜視図である。 FIG. 11 is a cross-sectional view of the dust collecting container according to Embodiment 3 of the present invention during cleaning. FIG. 12 is an enlarged cross-sectional view of a main part at the time of cleaning the filter part of the dust collecting container in the third embodiment of the present invention. FIG. 13: is a perspective view at the time of the cleaning of the filter part of the dust collecting container in Embodiment 3 of this invention.
　本実施の形態の電気掃除機は、集塵容器１９の一次フィルター部３５の一次フィルター枠体３８を二次フィルター部３６に回動自在に取り付け、一次フィルター枠体３８に当接突起部４９を設けた点で実施の形態１の電気掃除機とは異なる。 In the vacuum cleaner of the present embodiment, the primary filter frame 38 of the primary filter portion 35 of the dust collecting container 19 is rotatably attached to the secondary filter portion 36, and the contact protrusion 49 is provided on the primary filter frame 38. It differs from the electric vacuum cleaner of Embodiment 1 in the point provided.
　つまり、図１１および図１２に示すように、二次フィルター枠体４０に設けられた第２の軸受け部４７は、一次フィルター枠体３８に設けられた第２の軸支部４８に回動自在に支持されている。これにより、一次フィルター枠体３８は、二次フィルター部３６に回動自在に取り付けられる。 That is, as shown in FIGS. 11 and 12, the second bearing portion 47 provided in the secondary filter frame body 40 is rotatable to the second shaft support portion 48 provided in the primary filter frame body 38. It is supported. Thereby, the primary filter frame 38 is rotatably attached to the secondary filter portion 36.
　また、一次フィルター部３５の上流側の下部、すなわち、一次フィルター部３５の集塵容器１９側の下部には、当接突起部４９が設けられている。当接突起部４９は、蓋体３１を開放した状態で、一次フィルター部３５を集塵容器本体３０側（図１１の矢印Ｂ方向）に回動させると、蓋体３１の端部３１ａと当接して固定される。つまり、一次フィルター部３５を矢印Ｂ方向に回動させると、蓋体３１の一部が変形して当接突起部４９が、蓋体３１の端部に滑り込み、蓋体３１の端部３１ａを変形させて、一次フィルター部３５の当接突起部４９が蓋体３１の端部３１ａに一次フィルター部３５が保持される。なお、一次フィルター部３５を元の位置に戻す（矢印Ｂとは反対方向に回動させた）場合、当接突起部４９は、蓋体３１の端部３１ａを変形させて押し上げることにより、当接突起部４９が端部３１ａから開放される。そして、蓋体３１の端部３１ａが元に戻るとともに、一次フィルター部３５は、二次フィルター部３６と組み合わされた、フィルター部３２を構成する状態に戻る。 Further, an abutting protrusion 49 is provided on the lower part on the upstream side of the primary filter part 35, that is, on the lower part on the dust collecting container 19 side of the primary filter part 35. When the primary filter portion 35 is rotated toward the dust container main body 30 (in the direction of arrow B in FIG. 11) with the lid 31 open, the contact protrusion 49 contacts the end 31a of the lid 31. Fixed in contact. That is, when the primary filter portion 35 is rotated in the direction of arrow B, a part of the lid body 31 is deformed, and the contact protrusion 49 slides into the end portion of the lid body 31, and the end portion 31a of the lid body 31 is moved. The primary filter portion 35 is held by the end 31 a of the lid 31 by the contact protrusion 49 of the primary filter portion 35 being deformed. When the primary filter 35 is returned to the original position (rotated in the direction opposite to the arrow B), the contact protrusion 49 deforms and pushes up the end 31a of the lid 31 to The contact projection 49 is released from the end 31a. And while the edge part 31a of the cover body 31 returns, the primary filter part 35 will return to the state which comprises the filter part 32 combined with the secondary filter part 36. FIG.
　なお、図１１に示すように、一次フィルター部３５の上部に、凸形状の筋状突起部５０を設けてもよい。これにより、使用者が塵埃の付着した一次フィルター部３５に触れる面積を小さくすることができ、集塵容器１９の使い勝手を向上させることができる。 As shown in FIG. 11, a convex streak portion 50 may be provided on the upper portion of the primary filter portion 35. Thereby, the area which a user touches the primary filter part 35 to which dust adhered can be made small, and the usability of the dust collecting container 19 can be improved.
　また、図５に示すように、一次フィルター部３５の上部３５ａは、上流側に向かって下方に傾斜するように形成してもよい。具体的には、一次フィルター部３５の上部３５ａが、シール部材４１側から開口部３０ｂ側に向かって開口部３０ｂ側が低い位置となるように傾斜させる。 Further, as shown in FIG. 5, the upper part 35a of the primary filter part 35 may be formed so as to be inclined downward toward the upstream side. Specifically, the upper part 35a of the primary filter part 35 is inclined so that the opening part 30b side becomes a lower position from the seal member 41 side toward the opening part 30b side.
　これにより、使用者が一次フィルター部３５を掃除した際に、一次フィルター部３５の上面および内面に付着した塵埃が落ちやすくなり、一次フィルター部３５を容易に掃除することができる。その結果、集塵容器１９の使い勝手を向上させることができる。 Thereby, when the user cleans the primary filter part 35, the dust adhering to the upper surface and the inner surface of the primary filter part 35 becomes easy to drop, and the primary filter part 35 can be easily cleaned. As a result, the usability of the dust collection container 19 can be improved.
　以上のように構成された集塵容器１９内に堆積した塵埃を廃棄した後の動作について、図１３を参照しながら以下に説明する。 The operation after discarding the dust accumulated in the dust collecting container 19 configured as described above will be described below with reference to FIG.
　図１３に示すように、まず、使用者は、集塵容器本体３０の側面に配置された図４に示す掃除用ブラシ４４を用いて、一次フィルター３７および二次フィルター３９に付着した塵埃を掃除する。このとき、二次フィルター３９に付着した塵埃を掃除する場合、一次フィルター部３５と二次フィルター部３６との嵌合を解除して、第２の軸支部４８を介して一次フィルター部３５を回動させて、一次フィルター部３５と二次フィルター部３６を開放させる。そして、一次フィルター部３５の当接突起部４９を蓋体３１の端部３１ａと当接させて固定して、開放状態を保持する。 As shown in FIG. 13, first, the user cleans the dust adhering to the primary filter 37 and the secondary filter 39 using the cleaning brush 44 shown in FIG. 4 arranged on the side surface of the dust collecting container body 30. To do. At this time, when cleaning the dust adhering to the secondary filter 39, the fitting of the primary filter part 35 and the secondary filter part 36 is released, and the primary filter part 35 is rotated via the second shaft support part 48. The primary filter part 35 and the secondary filter part 36 are opened by moving. Then, the contact protrusion 49 of the primary filter portion 35 is fixed in contact with the end 31a of the lid 31 to maintain the open state.
　なお、上記実施に形態において、フィルター部３２は、蓋体３１に、例えばネジなどで取り付けられているが、これに限らない。例えば、フィルター部３２に蓋体３１を単にはめ込む構成としてもよい。これにより、フィルター部３２と蓋体３１とを容易に分離できるので、フィルター部３２内の掃除が容易にできる。 In the above embodiment, the filter unit 32 is attached to the lid 31 with, for example, a screw, but is not limited thereto. For example, a configuration in which the lid 31 is simply fitted into the filter portion 32 may be adopted. Thereby, since the filter part 32 and the cover body 31 can be isolate | separated easily, the cleaning in the filter part 32 can be performed easily.
　本発明の集塵容器によれば、生産コストを低減した集塵容器を用いることで、家庭用電気掃除機および産業用電気掃除機の分野・用途に好適に適用することができる。 The dust collection container of the present invention can be suitably applied to the fields and applications of household vacuum cleaners and industrial vacuum cleaners by using dust collection containers with reduced production costs.
