　本出願は、２０１５年９月１４日に出願した日本国特許出願第２０１５－１８０７５８号及び２０１５年９月１４日に出願した日本国特許出願第２０１５－１８１０１３号による優先権の利益に基礎をおき、かつ、その利益を求めており、その内容全体が引用によりここに包含される。 This application is based on the benefit of priority by Japanese Patent Application No. 2015-180758 filed on September 14, 2015 and Japanese Patent Application No. 2015-181010 filed on September 14, 2015. And seeking its benefits, the entire contents of which are hereby incorporated by reference.
　本発明に係る実施形態は、電気掃除装置に関する。 Embodiments according to the present invention relate to a vacuum cleaner.
　ダストモップなどのダストコントロール製品と、ダストコントロール製品により掻き集められた塵を集塵容器に吸引する集塵装置と、を備える掃除装置が知られている。 2. Description of the Related Art A cleaning device including a dust control product such as a dust mop and a dust collector that sucks dust collected by the dust control product into a dust container is known.
　また、近年、自律して被掃除面を移動して塵埃を捕集する自律型の電気掃除機、いわゆるロボットクリーナが知られている。ロボットクリーナは、居室全体を掃除するため、数十分から時間単位の運転時間を要する。このため、ロボットクリーナは、留守中の居室を自律的に掃除させることに高い利便性を有している一方で、例えば子供が食べこぼした菓子の屑を掃除するような用途の場合、つまり居室の一部を即座に掃除するような用途では勢い、利便性が低下してしまう。子供が食べこぼした菓子の屑を掃除するような用途では、自律型の電気掃除機以外の手段、例えばモップや、ほうきや、フロア用掃除具で塵埃を掃き集める手段の方が、迅速に対応できる。 In recent years, autonomous vacuum cleaners that autonomously move the surface to be cleaned and collect dust, so-called robot cleaners, are known. Robot cleaners require several tens of minutes to hours of operation time to clean the entire room. For this reason, the robot cleaner has a high convenience in autonomously cleaning the living room when it is away, while it is used for cleaning confectionery scraps spilled by a child, for example, the living room. In applications where a part of the screen is immediately cleaned, momentum and convenience are reduced. For applications that clean up confectionery scraps that children have spilled, means other than autonomous vacuum cleaners, such as mops, brooms, and floor sweepers, can be used more quickly. it can.
　しかしながら、自律型掃除ユニット以外の手段、例えばモップや、ほうきや、フロア用掃除具で塵埃を掃き集める手段の方が、迅速に対応できる場合であっても、掃き集めた後の塵埃の処分には、ちりとりを必要とするような別途の手間が掛かってしまうという側面もある。 However, even if a means other than the autonomous cleaning unit, such as a mop, broom, or floor sweeper, can quickly handle dust, it can be used to dispose of dust after sweeping. However, there is also an aspect that it takes extra effort that requires dust removal.
　また、自律型の電気掃除装置として、自律して被掃除面を移動して塵埃を捕集する自律型掃除ユニットと、自律型掃除ユニットから廃棄される塵埃を蓄積するステーションユニットと、を組み合わせた電気掃除装置が知られている。この種の電気掃除装置は、自律型掃除ユニットからステーションユニットへ塵埃を移送するために、自律型掃除ユニットとステーションユニットとを流体的に接続する。ステーションユニットは、自律型掃除ユニットの第一集塵容器に連結されて流体的に接続される塵埃移送管と、塵埃移送管を通じて第一集塵容器から廃棄される塵埃を蓄積する第二集塵容器と、第二集塵容器を介して塵埃移送管に吸い込み負圧を作用させる第二電動送風機と、を備えている。 Moreover, as an autonomous electric cleaning device, an autonomous cleaning unit that autonomously moves the surface to be cleaned and collects dust and a station unit that accumulates dust discarded from the autonomous cleaning unit are combined. A vacuum cleaner is known. This type of electric vacuum cleaner fluidly connects the autonomous cleaning unit and the station unit in order to transfer dust from the autonomous cleaning unit to the station unit. The station unit includes a dust transfer pipe that is fluidly connected to the first dust collection container of the autonomous cleaning unit, and a second dust collection that accumulates dust discarded from the first dust collection container through the dust transfer pipe. A container and a second electric blower that sucks and applies a negative pressure to the dust transfer pipe via the second dust collecting container.
　従来の電気掃除装置のステーションユニットは、空気から塵埃を濾し取って分離するフィルタを採用した濾過分離式の集塵容器（第二集塵容器）を備えていた。濾過分離式の集塵容器は、塵埃の蓄積量が増加するとフィルタが目詰まって吸込負圧が弱まり、自律型掃除ユニットから塵埃を移送する能力が徐々に低下してしまう。また、濾過分離式の集塵容器は、塵埃を廃棄した直後、つまり未だ塵埃を蓄積していない時期であっても、フィルタの濾過面を一気に塞ぐような塵埃、例えば多量の粉体を吸い込んで濾過面の目が塞がれると、自律型掃除ユニットから塵埃を移送することができなくなる場合がある。その一方で、自律型掃除ユニットには、数日から数週間程度の長期に亘って、気に掛けたり、手入れをしたりすることなく、いわゆるメンテナンスフリーな状態で使用し続けられることが望まれている。つまり、自律型掃除ユニットからステーションユニットへ塵埃を移送する機能は、塵埃の性質によらず、極力長期間に亘って発揮されることが望まれる。 The station unit of a conventional electric vacuum cleaner was equipped with a filtration separation type dust collection container (second dust collection container) that employs a filter that filters out and separates dust from the air. In the filter-separated dust collecting container, when the accumulated amount of dust increases, the filter becomes clogged, the suction negative pressure is weakened, and the ability to transfer dust from the autonomous cleaning unit gradually decreases. In addition, the filter-separated dust collecting container sucks in dust, such as a large amount of powder, immediately after discarding the dust, that is, even when the dust has not yet accumulated. If the filtration surface is blocked, dust may not be transferred from the autonomous cleaning unit. On the other hand, it is desirable for autonomous cleaning units to continue to be used in a so-called maintenance-free state for a long period of time, from several days to several weeks, without concern or care. ing. That is, it is desired that the function of transferring dust from the autonomous cleaning unit to the station unit is exhibited over a long period of time as much as possible regardless of the nature of the dust.

　第一フィルタ部９３は、集塵容器９２内に納められて略同心に配置されている。第一フィルタ部９３と集塵容器９２とを隔てる環状の空間は、集塵容器９２の吸気口９８から第一遠心分離部８１に流れ込む含塵空気を旋回させて粗い塵埃を遠心分離する第一遠心分離室９１である。 The first filter part 93 is housed in the dust collecting container 92 and is arranged substantially concentrically. An annular space that separates the first filter unit 93 and the dust collecting container 92 is a first unit that centrifuges coarse dust by rotating the dust-containing air flowing into the first centrifugal separating unit 81 from the air inlet 98 of the dust collecting container 92. This is a centrifuge chamber 91.
　第一フィルタ部９３は、第二遠心分離部８２に固定されて、集塵容器９２内部に突出して集塵容器９２の底壁へ向かって延びている。第一フィルタ部９３は、第一遠心分離室９１と第二遠心分離部８２とを流体的に接続して中継している。第一フィルタ部９３は、互いに離間されて円筒形状に配置される複数の骨１０６を有する枠体１０７と、枠体１０７の周囲を円筒形状に囲む第一メッシュフィルタ１０８と、を備えている。枠体１０７の骨１０６の間の第一開口１０９は、第一遠心分離室９１から第二遠心分離部８２へ空気を流出させる。第一フィルタ部９３の側面、詳しくは、第一メッシュフィルタ１０８は、吸気口９８を臨んでいる。 The first filter part 93 is fixed to the second centrifugal separator 82, protrudes into the dust container 92 and extends toward the bottom wall of the dust container 92. The first filter unit 93 relays the first centrifuge chamber 91 and the second centrifuge unit 82 in fluid connection. The first filter unit 93 includes a frame body 107 having a plurality of bones 106 that are spaced apart from each other and arranged in a cylindrical shape, and a first mesh filter 108 that surrounds the periphery of the frame body 107 in a cylindrical shape. The first opening 109 between the bones 106 of the frame 107 allows air to flow from the first centrifuge chamber 91 to the second centrifuge 82. The side surface of the first filter portion 93, specifically, the first mesh filter 108 faces the air inlet 98.
　第一メッシュフィルタ１０８は第二電動送風機６９の始動直後や停止過渡など、第一遠心分離室９１内の旋回流が十分に発達していない期間において、また旋回流が発達した後も当然に、第一遠心分離部８１から第二遠心分離部８２側へ粗い塵埃が流れ込むことを防いでいる。 Naturally, the first mesh filter 108 is in a period in which the swirl flow in the first centrifugal separation chamber 91 is not sufficiently developed, such as immediately after the start of the second electric blower 69 or a stop transition, and after the swirl flow has developed. Coarse dust is prevented from flowing from the first centrifuge 81 to the second centrifuge 82 side.
　なお、第一フィルタ部９３は、粗い塵埃が下流側へ流れ込むことを阻止できる程度において、必ずしも第一メッシュフィルタ１０８を必要としない。例えば、第一フィルタ部９３の枠体１０７が、粗い塵埃の通過を阻止できる程度に目の細かい格子状であったり、粗い塵埃の通過を阻止できる程度に小さい孔を有していたりする場合には、必ずしも第一メッシュフィルタ１０８を必要としない。 The first filter unit 93 does not necessarily require the first mesh filter 108 to the extent that coarse dust can be prevented from flowing downstream. For example, when the frame body 107 of the first filter portion 93 has a lattice shape that is fine enough to prevent the passage of coarse dust or has holes that are small enough to prevent the passage of coarse dust. Does not necessarily require the first mesh filter 108.
　塵埃捕捉カップ９５は、第一フィルタ部９３のうち集塵容器９２の底壁に近い端部、つまり突出端部、または下端部に設けられている。有底円筒形状の塵埃捕捉カップ９５は、第一フィルタ部９３に連接する底壁と、集塵容器９２の底壁に向かって延びる側壁と、を有している。つまり、塵埃捕捉カップ９５は、集塵容器９２の底壁に向かって開放されている。塵埃捕捉カップ９５の側壁は、隙間を隔てて集塵容器９２の内周面に対向している。塵埃捕捉カップ９５は、第一フィルタ部９３よりも大径であり、第一フィルタ部９３に連接する底壁に第二開口１１１を有している。 The dust capturing cup 95 is provided at an end portion of the first filter portion 93 close to the bottom wall of the dust collecting container 92, that is, a protruding end portion or a lower end portion.

That is, the dust capturing cup 95 is opened toward the bottom wall of the dust collecting container 92. The side wall of the dust catching cup 95 faces the inner peripheral surface of the dust collecting container 92 with a gap. The dust trapping cup 95 has a larger diameter than the first filter portion 93 and has a second opening 111 on the bottom wall connected to the first filter portion 93.
　塵埃捕捉カップ９５と集塵容器９２とを隔てる空間は、第一遠心分離部８１で分離された塵埃を蓄積する集塵室９７である。集塵室９７内の空気は、第二開口１１１を通じて第一遠心分離室９１へ戻る。 A space separating the dust capturing cup 95 and the dust collecting container 92 is a dust collecting chamber 97 for accumulating dust separated by the first centrifugal separator 81. The air in the dust collection chamber 97 returns to the first centrifuge chamber 91 through the second opening 111.
　第二開口１１１には、第二メッシュフィルタ１１２が設けられている。第二メッシュフィルタ１１２は、集塵室９７に流れ込んだ粗い（糸くずや綿埃などの繊維状の）塵埃が第一遠心分離室９１へ戻らない程度に目の粗いもので良い。 A second mesh filter 112 is provided in the second opening 111. The second mesh filter 112 may be coarse so that coarse dust (fibrous such as lint and cotton dust) flowing into the dust collecting chamber 97 does not return to the first centrifugal separation chamber 91.
　第二集塵容器６８から集塵容器９２を取り外すと、第一フィルタ部９３および塵埃捕捉カップ９５は、第二遠心分離部８２に随伴して集塵容器９２から抜け出る。 When the dust collecting container 92 is removed from the second dust collecting container 68, the first filter part 93 and the dust catching cup 95 come out of the dust collecting container 92 along with the second centrifugal separating part 82.
　第二遠心分離部８２は、第一遠心分離部８１を通過する含塵空気から細かい塵埃を分離する。第二遠心分離部８２は、第一遠心分離室９１を通過した空気を導く中継風路１１３と、中継風路１１３から流れ込む空気から細かい塵埃を分離する第二遠心分離室１１５と、細かい塵埃が分離された後に第二遠心分離室１１５から流出する空気を第二電動送風機６９へ導く排気風路８５と、を備えている。 The second centrifugal separator 82 separates fine dust from the dust-containing air passing through the first centrifugal separator 81. The second centrifugal separator 82 includes a relay air passage 113 that guides air that has passed through the first centrifugal separation chamber 91, a second centrifugal separation chamber 115 that separates fine dust from the air flowing from the relay air passage 113, and fine dust And an exhaust air passage 85 that guides the air flowing out from the second centrifugal separation chamber 115 to the second electric blower 69 after being separated.
　第二遠心分離部８２は、集塵容器９２に着脱自在に連結されて集塵容器９２の開放端９２ａを塞いでいる。また、第二遠心分離部８２は、第一フィルタ部９３および塵埃捕捉カップ９５を集塵容器９２の中心線Ｃ上に支持している。 The second centrifugal separator 82 is detachably connected to the dust collecting container 92 and closes the open end 92a of the dust collecting container 92. In addition, the second centrifugal separator 82 supports the first filter part 93 and the dust capturing cup 95 on the center line C of the dust collecting container 92.

　円筒形状壁１１６は、円錐台形状壁１１７よりも第一遠心分離部８１から遠い側に配置されている。円筒形状壁１１６の側壁には、含塵空気の導入口１１８が設けられている。導入口１１８は、円筒形状壁１１６の側面であって、第二集塵容器６８の中心側に配置され、中継風路１１３に接続されている。 The cylindrical wall 116 is disposed on the side farther from the first centrifuge 81 than the truncated cone wall 117. On the side wall of the cylindrical wall 116, a dust-containing air inlet 118 is provided. The introduction port 118 is a side surface of the cylindrical wall 116 and is disposed on the center side of the second dust collecting container 68 and is connected to the relay air passage 113.

The dust trap umbrella 125 is provided at the base of the first filter portion 93 so as to serve as a partition wall that partitions the first centrifugal separation portion 81 and the second centrifugal separation portion 82. The outer diameter of the dust trap umbrella 125 is smaller than that of the second centrifugal separator 82 and larger than that of the first filter portion 93. The dust trap umbrella 125 has one surface 125a that guides fine dust discharged from the disposal port 122 of the second centrifuge chamber 115 to the dust collection container 92 and the other surface 125b that extends and inclines toward the dust collection container 92.

The large-diameter portion 101, the inclined portion 102, and the dust trap umbrella 125 of the dust collection container 92 partition the fine dust collection chamber 126 that accumulates dust discharged from the second centrifugal separation chamber 115. The fine dust collecting chamber 126 is sandwiched between the inner surface of the large-diameter portion 101, the inclined surface of the inclined portion 102, and one surface 125a of the dust trapping umbrella 125, that is, the farther away from the second centrifuge chamber 115, that is, the second This is a substantially wedge-shaped space that becomes narrower as the distance from the disposal port 122 of the centrifuge chamber 115 increases.
　塵埃捕捉傘１２５の他方の面１２５ｂは、第一フィルタ部９３および塵埃捕捉カップ９５よりも大径であり、かつ第一フィルタ部９３および塵埃捕捉カップ９５に向かって拡径されている。 The other surface 125 b of the dust trapping umbrella 125 is larger in diameter than the first filter portion 93 and the dust trapping cup 95 and is expanded toward the first filter portion 93 and the dust trapping cup 95.

At this time, the dust transfer pipe 25 of the station unit 5 is connected to the connecting portion 39 of the first dust collecting container 12. Thereafter, the station unit 5 drives the second electric blower 69 to suck in air and moves the dust from the first dust collecting container 12 to the second dust collecting container 68. The second dust collecting container 68 separates coarse coarse dust from the air by the first centrifugal separator 81 and accumulates it in the dust collecting chamber 97. The second dust collecting container 68 separates fine dust from the air that has passed through the first centrifugal separator 81 by the second centrifugal separator 82 and accumulates it in the fine dust collecting chamber 126.

The second electric blower 69 is operated by the function of a sensor (not shown) that senses that it is approaching itself. The negative pressure generated by the operation of the second electric blower 69 acts on the second suction port 65 of the station unit 5 through the second dust collecting container 68 and sucks dust from the second suction port 65. Dust sucked from the second suction port 65 adheres to means other than the autonomous cleaning unit 2, for example, dust collected by a mop, broom, or floor cleaning tool, or mop, broom, or floor cleaning tool itself. Dust.

The dust transfer tube 25 preferably has a protruding length that can reach the connecting portion 39 through the dust container port 37.
　廃棄口４１は、第一集塵容器１２が第一本体ケース１１に取り付けられた状態において、自律型掃除ユニット２の下方へ向かって開口されている。 The disposal port 41 is opened downward of the autonomous cleaning unit 2 in a state where the first dust collecting container 12 is attached to the first main body case 11.
　廃棄口４１は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）関係において、自律型掃除ユニット２の中央よりもステーションユニット５に近い側に配置されている。つまり、廃棄口４１は、自律型掃除ユニット２が後退してステーションユニット５へ近づき、一対の駆動輪４５をステーションユニット５の台座２１に乗り上げると、ステーションユニット５の塵埃回収部２２に近づく。 The disposal port 41 is disposed closer to the station unit 5 than the center of the autonomous cleaning unit 2 in relation to the position (homing position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3. That is, the disposal port 41 approaches the dust collection unit 22 of the station unit 5 when the autonomous cleaning unit 2 moves backward and approaches the station unit 5 and rides the pair of drive wheels 45 on the base 21 of the station unit 5.
　廃棄蓋４２は、自律型掃除ユニット２の外観に露出しており、第一本体ケース１１の外表面に面一である。廃棄蓋４２は、ステーションユニット５のレバー２６を引っ掛けるレバー受１３１を備えている。なお、廃棄蓋４２も、連結部３９と同様に第一本体ケース１１に取り付けられた状態において塵埃容器口３７を臨む箇所に配置されていても良い。この場合、廃棄蓋４２は、第一本体ケース１１の内側であって塵埃容器口３７から見通すことができる場所に配置される。 The disposal lid 42 is exposed to the external appearance of the autonomous cleaning unit 2 and is flush with the outer surface of the first main body case 11. The waste lid 42 includes a lever receiver 131 that hooks the lever 26 of the station unit 5. The disposal lid 42 may also be disposed at a location facing the dust container port 37 in a state of being attached to the first main body case 11 like the connecting portion 39. In this case, the disposal lid 42 is disposed inside the first main body case 11 and in a place where it can be seen from the dust container port 37.
　他方、本実施形態に係るステーションユニット５のレバー２６は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ向かう途中で自律型掃除ユニット２の廃棄蓋４２に引っ掛かり、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ到達すると廃棄蓋４２を開いて廃棄口４１と塵埃移送管２５とを流体的に接続させる（図９）。 On the other hand, the lever 26 of the station unit 5 according to the present embodiment is attached to the disposal lid 42 of the autonomous cleaning unit 2 on the way to the position (home position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3. When it reaches the position where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3 (homing position), the disposal lid 42 is opened to fluidly connect the disposal port 41 and the dust transfer pipe 25 (FIG. 9). ).
　自律型掃除ユニット２の廃棄蓋４２およびステーションユニット５のレバー２６は、自律型掃除ユニット２が充電電極３に電気的に接続される位置へ向かう方向に交差する回転中心線Ｃ３のまわりに揺動する。なお、廃棄蓋４２の回転中心線Ｃ４およびレバー２６の回転中心線Ｃ３は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ向かう方向に対して直交していることが望ましい。 The waste cover 42 of the autonomous cleaning unit 2 and the lever 26 of the station unit 5 swing around a rotation center line C3 that intersects in a direction toward the position where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3. To do. The rotation center line C4 of the disposal lid 42 and the rotation center line C3 of the lever 26 are orthogonal to the direction toward the position (home position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3. It is desirable.
　レバー２６の回転中心線Ｃ３は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ向かう方向において塵埃移送管２５の開口縁部のうち自律型掃除ユニット２が最初に到達する縁部、つまり塵埃移送管２５の開口縁の前端部に配置されている。 The rotation center line C3 of the lever 26 indicates that the autonomous cleaning unit 2 in the opening edge of the dust transfer tube 25 is in the direction toward the position (homing position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3. It is arranged at the edge that reaches first, that is, at the front end of the opening edge of the dust transfer tube 25.
　また、レバー２６の回転中心線Ｃ３は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ向かう方向に移動自在に支持されている。つまり、フック７９は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ向かう方向にレバー２６の回転中心線Ｃ３が移動することによって、自律型掃除ユニット２の帰巣制御における位置精度のばらつきに影響されることなく、レバー受１３１に引っ掛かることができる。 The rotation center line C3 of the lever 26 is supported so as to be movable in a direction toward the position (home position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3. That is, the hook 79 moves the rotation center line C3 of the lever 26 in a direction toward the position (homing position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3. The lever receiver 131 can be hooked without being affected by variations in position accuracy in homing control.
　さらに、レバー２６の回転中心線Ｃ３は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ向かう方向において塵埃移送管２５の開口縁部のうち自律型掃除ユニット２が最初に到達する縁部、つまり塵埃移送管２５の開口縁の前端部に設けられる軸カバー１３２によって覆われている。 Further, the rotation center line C3 of the lever 26 is an autonomous cleaning unit of the opening edge of the dust transfer tube 25 in the direction toward the position (homing position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3. 2 is covered by a shaft cover 132 provided at the edge where it first reaches, that is, the front end of the opening edge of the dust transfer tube 25.
　廃棄蓋４２の回転中心線Ｃ４は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ向かう方向において廃棄蓋４２の遠方側に配置されている。また、廃棄蓋４２の回転中心線Ｃ４は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ向かう方向においてレバー受１３１よりも遠方側に配置されている。さらに、廃棄蓋４２の回転中心線Ｃ４は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ向かう方向において廃棄蓋４２のうち、廃棄口４１に接したり離れたりする蓋本体１３３よりも遠方側に配置されている。 The rotation center line C4 of the disposal lid 42 is arranged on the far side of the disposal lid 42 in the direction toward the position (homing position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3. Further, the rotation center line C4 of the disposal lid 42 is disposed farther than the lever receiver 131 in the direction toward the position (homing position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3. Further, the rotation center line C4 of the disposal lid 42 is in contact with or away from the disposal port 41 of the disposal lid 42 in the direction toward the position (homing position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3. The lid body 133 is arranged on the far side.
　これらレバー２６の回転中心線Ｃ３および廃棄蓋４２の回転中心線Ｃ４の配置によって、廃棄蓋４２は、レバー２６によって開かれると自律型掃除ユニット２の容器本体３８から塵埃移送管２５へ塵埃を案内する傾斜面になる（図９）。 Due to the arrangement of the rotation center line C3 of the lever 26 and the rotation center line C4 of the waste lid 42, the waste lid 42 guides dust from the container body 38 of the autonomous cleaning unit 2 to the dust transfer tube 25 when opened by the lever 26. (Fig. 9).
　なお、廃棄蓋４２は、閉じる方向へコイルバネ１３５のバネ力を受けている。廃棄蓋４２は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ向かう推進力がコイルバネ１３５のバネ力に勝ることによって開かれる。コイルバネ１３５は、レバー２６によって廃棄蓋４２が開かれると、押し潰されてエネルギーを蓄える一方、自律型掃除ユニット２がステーションユニット５から離脱してレバー受１３１からレバー２６が抜け出すと、エネルギーを解放して廃棄蓋４２を閉じる。 Note that the disposal lid 42 receives the spring force of the coil spring 135 in the closing direction. The disposal lid 42 is opened when the propulsive force toward the position (home position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3 exceeds the spring force of the coil spring 135. When the waste lid 42 is opened by the lever 26, the coil spring 135 is crushed and accumulates energy, while when the autonomous cleaning unit 2 is detached from the station unit 5 and the lever 26 comes out of the lever receiver 131, the energy is released. Then, the waste lid 42 is closed.
　レバー２６は、起立する（図８）方向へコイルバネ（図示省略）のバネ力を受けている。レバー２６は、自律型掃除ユニット２が充電電極３に電気的に接続される位置（帰巣位置）へ向かう推進力がコイルバネのバネ力に勝ることによって倒し込まれる。コイルバネは、レバー２６によって廃棄蓋４２が開かれると、押し潰されてエネルギーを蓄える一方、自律型掃除ユニット２がステーションユニット５から離脱してレバー受１３１からレバー２６が抜け出すと、エネルギーを解放してレバー２６を起立させる。 The lever 26 receives a spring force of a coil spring (not shown) in a direction to stand (FIG. 8). The lever 26 is pushed down when the propulsive force toward the position (home position) where the autonomous cleaning unit 2 is electrically connected to the charging electrode 3 exceeds the spring force of the coil spring. When the waste lid 42 is opened by the lever 26, the coil spring is crushed and accumulates energy. On the other hand, when the autonomous cleaning unit 2 leaves the station unit 5 and the lever 26 comes out of the lever receiver 131, the coil spring releases energy. To raise the lever 26.
　このように構成される本実施形態に係る電気掃除装置１は、塵埃移送管２５から流れ込む塵埃を空気から遠心分離する第一遠心分離部８１と、第一遠心分離部８１を通過する塵埃を空気から分離する第二遠心分離部８２と、を含む多段型の遠心分離部８３を備えることによって、塵埃の蓄積量が増加しても分離性能がほとんど低下せずに維持され、ひいては吸込負圧が維持され、自律型掃除ユニット２から塵埃を移送する能力を保つことができる。また、電気掃除装置１は、多段型の遠心分離部８３を備えることによって、仮に多量の粉体を一気に吸い込んでも吸込性能が突如損なわれることなく維持され、自律型掃除ユニット２から塵埃を移送する能力を維持できる。 The vacuum cleaner 1 according to the present embodiment configured as described above includes a first centrifuge 81 that centrifuges dust flowing from the dust transfer pipe 25 from air, and air that passes dust passing through the first centrifuge 81. And a second centrifuge unit 83 including a second centrifuge unit 82 that separates from the first and second centrifuge units 82, so that the separation performance is maintained with little deterioration even when the amount of accumulated dust increases, and the suction negative pressure is reduced. It is maintained and the ability to transfer dust from the autonomous cleaning unit 2 can be maintained. In addition, the vacuum cleaner 1 includes the multi-stage centrifugal separation unit 83, so that even if a large amount of powder is sucked at once, the suction performance is maintained without being suddenly lost, and dust is transferred from the autonomous cleaning unit 2. Ability can be maintained.
　さらに、本実施形態に係る電気掃除装置１は、ステーションユニット５の第二吸込口６５を有することによって、自律型掃除ユニット２以外の手段、例えばモップや、ほうきや、フロア用掃除具で集められる塵埃、またはモップや、ほうきや、フロア用掃除具自体に付着する塵埃を吸い込むことができる。電気掃除装置１のこのような塵埃の吸い取り機能は、居室の一部を局所的に掃除したい場合、例えば子供が食べこぼした菓子の屑のような塵埃を清掃することに適している。つまり、電気掃除装置１は、自律型掃除ユニット２を自律的に運転して居室全体を掃除する場合には数十分から時間単位を要する一方で、自律型掃除ユニット２以外の手段、例えばモップや、ほうきや、フロア用掃除具で居室内を局所的に掃除する場合には、数十秒から数分単位で塵埃を掃き集められる塵埃を、第二吸込口６５から即座に吸い取って蓄積することができる。 Furthermore, the electric vacuum cleaner 1 according to the present embodiment has the second suction port 65 of the station unit 5 so that it can be collected by means other than the autonomous cleaning unit 2, such as a mop, a broom, or a floor cleaning tool. Dust or dust adhering to mops, brooms, or the floor cleaning tool itself can be sucked in. Such a dust sucking function of the electric vacuum cleaner 1 is suitable for cleaning dust such as confectionery scraps spilled by a child when it is desired to locally clean a part of the living room. In other words, the electric vacuum cleaner 1 requires several tens of minutes to a time unit when the autonomous cleaning unit 2 is operated autonomously to clean the entire room, while means other than the autonomous cleaning unit 2 such as mop In addition, when a room is locally cleaned with a broom or a floor cleaning tool, dust that can be swept up in units of several tens of seconds to several minutes is immediately sucked from the second suction port 65 and accumulated. be able to.
　さらにまた、本実施形態に係る電気掃除装置１は、ステーションユニット５の第二吸込口６５から吸い込む塵埃を多段型の遠心分離部８３で蓄積するため、第二吸込口６５の吸引力を維持しやすい。 Furthermore, the vacuum cleaner 1 according to the present embodiment accumulates the dust sucked from the second suction port 65 of the station unit 5 in the multistage centrifugal separator 83, so that the suction force of the second suction port 65 is maintained. Cheap.
　このことは、第二吸込口６５の掃除対象を、例えばモップや、ほうきや、フロア用掃除具のように相応の幅寸法で塵埃を掃き集める掃除具に設定する場合において、第二吸込口６５の大きさを設置面に沿って幅広く、かつ相応の高さ寸法に設定したとしても、吸込負圧が長期に低下することなく、モップや、ほうきや、フロア用掃除具のような掃除具で掃き集められた塵埃を確実に吸い取ることを可能にする。 This means that the second suction port 65 is set when the object to be cleaned of the second suction port 65 is a cleaning tool that sweeps up dust with a suitable width dimension, such as a mop, broom, or floor cleaning tool. Even if the size of the is wide along the installation surface and set to a suitable height, the suction negative pressure does not decrease over the long term, and a cleaning tool such as a mop, broom, or floor cleaning tool is used. It is possible to surely suck up the dust collected.
　したがって、本実施形態に係る電気掃除装置１によれば、自律型掃除ユニット２からステーションユニット５へ塵埃を移送する能力が長期に亘って維持され、かつ多量の粉体を一気に吸い込んでも塵埃を移送する機能を維持しやすい。 Therefore, according to the vacuum cleaner 1 according to the present embodiment, the ability to transfer dust from the autonomous cleaning unit 2 to the station unit 5 is maintained over a long period of time, and dust is transferred even if a large amount of powder is sucked at once. Easy to maintain function.
　第３の実施形態によれば、自律型掃除ユニットからステーションユニットへ塵埃を移送する能力が長期に亘って維持され、かつ多量の粉体を一気に吸い込んでも塵埃を移送する機能を維持しやすい電気掃除装置が提供できる。 According to the third embodiment, the ability to transfer dust from the autonomous cleaning unit to the station unit is maintained over a long period of time, and the function of transferring dust even when a large amount of powder is sucked at once is easy to maintain. A device can be provided.
