It has been.
　集塵ケース本体201は、第２分離集塵部27を本体ケース25(の取付凹部44)に装着した状態で取付凹部44の下側に収容される部分であり、上側が開口しており、分離集塵部本体171の連結部183により開閉可能に覆われる。また、この集塵ケース本体201の内部には、左右幅方向に沿って板状の仕切り部201aが前後方向に複数設けられており、これら仕切り部201aによって、集塵ケース本体201の内部に複数の溜め部201bが前後方向に区画されている。そして、これら仕切り部201aが連結部183の下端に気密に接続されることにより、各溜め部201bが、左右幅方向に隣接する分離室181とそれぞれ連通するようになっている。さらに、この集塵ケース本体201は、中央列L1の各分離室181の下端側、換言すれば分離室181に対して整流部185(導入開口)と反対側に位置しており、本実施形態では中央列L1の分離室181の直下、すなわち中央列L1の分離室181の通気筒部189の中心軸の延長上に位置している。したがって、この集塵ケース本体201は、分離室181を介して窓部195(紫外線ランプ67)と反対側に位置している。 The dust collection case body 201 is a portion that is accommodated in the lower side of the mounting recess 44 in a state where the second separated dust collection portion 27 is mounted on the body case 25 (the mounting recess 44 thereof), and the upper side is open. Covered by the connecting portion 183 of the separated dust collecting body 171 is openable and closable. In addition, a plurality of plate-like partition portions 201a are provided in the front-rear direction along the left-right width direction inside the dust collection case body 201, and a plurality of partition portions 201a are provided inside the dust collection case body 201 by the partition portions 201a. The reservoir 201b is partitioned in the front-rear direction. These partition portions 201a are hermetically connected to the lower ends of the connecting portions 183, so that the respective reservoir portions 201b communicate with the separation chambers 181 adjacent in the left-right width direction. Further, the dust collection case body 201 is located on the lower end side of each separation chamber 181 in the central row L1, in other words, on the opposite side of the rectification unit 185 (introduction opening) with respect to the separation chamber 181. Then, it is located directly under the separation chamber 181 in the central row L1, that is, on the extension of the central axis of the cylinder passing portion 189 of the separation chamber 181 in the central row L1. Therefore, the dust collection case body 201 is located on the opposite side of the window 195 (ultraviolet lamp 67) through the separation chamber 181.
　また、受け部203は、連結部183の下端部を支持し、この連結部183の下端部が気密に接続される部分である。 Further, the receiving portion 203 is a portion that supports the lower end portion of the connecting portion 183, and the lower end portion of the connecting portion 183 is airtightly connected.
　次に、上記第１の実施形態の作用を説明する。 Next, the operation of the first embodiment will be described.
　掃除の際には、第１分離集塵部26および第２分離集塵部27をそれぞれ掃除機本体13の本体ケース25に予め装着しておく。 At the time of cleaning, the first separated dust collecting part 26 and the second separated dust collecting part 27 are previously attached to the main body case 25 of the cleaner body 13 respectively.
　第２分離集塵部27の取り付けに際しては、取付凹部44に本体部32の前方から挿入して押し込むことで、第２分離集塵部27が第２着脱機構により本体ケース25に固定される。この状態で、流出風路部178の下流端である流出開口部194の縁部が連通口シール部材64に圧接されて連通口63と気密に接続されるとともに、窓部195(透過部材195a)が僅かな隙間を介して紫外線ランプ67に近接して対向する。 When attaching the second separated dust collecting portion 27, the second separated dust collecting portion 27 is fixed to the main body case 25 by the second attaching / detaching mechanism by inserting and pushing the second separated dust collecting portion 27 into the mounting recess 44 from the front of the main body portion 32. In this state, the edge of the outflow opening 194, which is the downstream end of the outflow air passage portion 178, is pressed against the communication port seal member 64 and is hermetically connected to the communication port 63, and the window 195 (transmission member 195a) Is opposed to the ultraviolet lamp 67 through a slight gap.
　また、第１分離集塵部26の取り付けに際しては、取手部152を把持した状態で突出部33上に蓋体132の前側下部を載置し、この前側下部を中心として後方へと回動させる。すると、第１分離集塵部26が本体ケース25に対して左右幅方向に位置決めされつつ、第１着脱機構により本体ケース25に固定される。この状態で、第１分離集塵部26の流入口135の縁部が、連通開口シール部材104に圧接されて連通開口103と気密に接続されるとともに、排出口154の排出口シール部材155が第２分離集塵部27の流入開口部182eの縁部と圧接されて排出口154と流入開口部182eとが気密に接続される。また、第１分離集塵部26の取手部152の後端側が本体ケース25の配置部66の前端側に連結される。 Further, when attaching the first separated dust collecting portion 26, the front lower portion of the lid body 132 is placed on the protruding portion 33 while the handle portion 152 is gripped, and is rotated rearward around the front lower portion. . Then, the first separated dust collecting part 26 is fixed to the main body case 25 by the first attaching / detaching mechanism while being positioned in the left-right width direction with respect to the main body case 25. In this state, the edge portion of the inlet 135 of the first separation dust collecting portion 26 is pressed against the communication opening seal member 104 and hermetically connected to the communication opening 103, and the discharge port seal member 155 of the discharge port 154 is The discharge port 154 and the inflow opening 182e are hermetically connected by being pressed against the edge of the inflow opening 182e of the second separated dust collecting portion 27. Further, the rear end side of the handle portion 152 of the first separated dust collecting portion 26 is connected to the front end side of the arrangement portion 66 of the main body case 25.
　したがって、第１分離集塵部26と第２分離集塵部27とを介して、管部12と電動送風機31の吸込側とが気密に接続されて風路Ｗが形成される。 Therefore, the air passage W is formed by airtightly connecting the pipe portion 12 and the suction side of the electric blower 31 via the first separated dust collecting portion 26 and the second separated dust collecting portion 27.
　そして、使用者は、電源部121により給電可能とした状態で、把持部21を把持して所望の設定ボタン22を操作することにより、制御手段が電動送風機31を位相角制御し、設定ボタン22の操作により設定された動作モードで電動送風機31を駆動させる。 Then, in a state where power can be supplied by the power supply unit 121, the user operates the desired setting button 22 by holding the holding unit 21, so that the control unit controls the phase angle of the electric blower 31, and the setting button 22 The electric blower 31 is driven in the operation mode set by the operation.
　電動送風機31の駆動により生じた負圧は、下流側ダクト部39の連通風路部115、連通口63、第２分離集塵部27、第１分離集塵部26、連通開口103、上流側ダクト部38および本体吸込口107を介して管部12へと作用する。そして、管部12では、ホース体16、延長管18および床ブラシ19と負圧が作用して、被掃除面に載置した床ブラシ19の先端などから、塵埃を空気とともに吸い込む。 The negative pressure generated by the driving of the electric blower 31 is the communication air passage portion 115, the communication port 63, the second separation dust collection portion 27, the first separation dust collection portion 26, the communication opening 103, the upstream side of the downstream duct portion 39. It acts on the pipe part 12 through the duct part 38 and the main body suction port 107. In the pipe portion 12, negative pressure acts on the hose body 16, the extension pipe 18, and the floor brush 19, and dust is sucked together with air from the tip of the floor brush 19 placed on the surface to be cleaned.
　含塵空気は、床ブラシ19、延長管18およびホース体16を介して、本体吸込口107から上流側ダクト部38の連通開口103を介して第１分離集塵部26のケース体125の内部へと流入口135を介して流入する。この流入口135から流入した含塵空気は、ケース体125(ケース本体131)と旋回部126の旋回部本体161との間で周方向に旋回し、粗塵が遠心分離されて下方へと重力落下し、第１分離集塵部26のケース体125(ケース本体131)の下部に捕集される。 The dust-containing air passes through the floor brush 19, the extension pipe 18, and the hose body 16, and passes through the communication opening 103 of the upstream duct portion 38 from the main body suction port 107 to the inside of the case body 125 of the first separation dust collection portion 26. Through the inlet 135. The dust-containing air flowing in from the inlet 135 swirls in the circumferential direction between the case body 125 (case body 131) and the swivel part body 161 of the swivel part 126, and the coarse dust is centrifuged and gravity is lowered. It falls and is collected in the lower part of the case body 125 (case body 131) of the first separated dust collection unit 26.
　この第１分離集塵部26内を旋回する含塵空気は、集塵フィルタ167を介して通気開口部166から旋回部本体161の内部へと流入する。そして、この集塵フィルタ167の通過の際には、この含塵空気中の粗塵よりも細かい塵埃が集塵フィルタ167に捕集される。また、第１分離集塵部26内を旋回する含塵空気の一部は、圧縮部162側へと流れ、圧縮フィルタ169を介して連通開口部168から旋回部本体161の内部へと流入する。そして、この圧縮フィルタ169の通過の際には、この含塵空気中の粗塵よりも細かい塵埃が圧縮フィルタ169に捕集されるとともに、ケース体125(ケース本体131)内に捕集された塵埃が圧縮フィルタ169に押し付けられて圧縮される。 The dust-containing air swirling in the first separation dust collecting portion 26 flows from the ventilation opening 166 into the swirling portion main body 161 through the dust collecting filter 167. When passing through the dust collection filter 167, dust finer than coarse dust in the dust-containing air is collected by the dust collection filter 167. Part of the dust-containing air swirling in the first separated dust collecting section 26 flows toward the compression section 162 and flows into the swiveling section main body 161 from the communication opening 168 via the compression filter 169. . When passing through the compression filter 169, dust finer than coarse dust in the dust-containing air is collected in the compression filter 169 and also collected in the case body 125 (case body 131). Dust is pressed against the compression filter 169 and compressed.
　旋回部本体161内を通過した含塵空気(細塵を含んだ空気)は、連結風路153を通過した後、排出口154から排出されて流入開口部182eから流入風路部177へと流入し、第２分離集塵部27の各整流部185の整流通路部188へと導入開口からそれぞれ分岐して流入し、これら整流通路部188により整流されつつ各分離室181内へと流入する。 The dust-containing air that has passed through the inside of the swivel unit body 161 (air containing fine dust) passes through the connection air passage 153, is then discharged from the discharge port 154, and flows into the inflow air passage portion 177 from the inflow opening 182e. Then, the air flows into the rectifying passage portions 188 of the respective rectifying portions 185 of the second separation dust collecting portion 27 from the introduction opening and flows into the separation chambers 181 while being rectified by the rectifying passage portions 188.
　これら分離室181に流入した含塵空気は、これら分離室181の内周面に沿って周方向に、第１分離集塵部26のケース体125内での旋回の流速よりも大きな流速で旋回し、細塵(微細塵)が遠心分離されて各分離室181の下端部から連結部183を介して集塵ケース172へとそれぞれ重力落下し、この集塵ケース172の集塵ケース本体201の各溜め部201b内に捕集される。細塵(微細塵)が除去された澄んだ空気は、整流部185の通気筒部189を通過して流出風路部178へと抽出されて互いに合流する。 The dust-containing air that has flowed into the separation chamber 181 swirls in the circumferential direction along the inner peripheral surface of the separation chamber 181 at a flow velocity greater than the swirling flow velocity in the case body 125 of the first separation dust collection unit 26. Then, fine dust (fine dust) is centrifuged and gravity falls from the lower end of each separation chamber 181 to the dust collecting case 172 via the connecting portion 183, and the dust collecting case main body 201 of the dust collecting case 172 It is collected in each reservoir 201b. The clear air from which fine dust (fine dust) has been removed passes through the cylinder 189 of the rectifying unit 185, is extracted to the outflow air passage unit 178, and merges with each other.
　そして、流出風路部178に合流した空気は流出開口部194から連通口63を介して下流側ダクト部39の連通風路部115から電動送風機室部内の電動送風機31へと吸い込まれ、この電動送風機31内を通過してこの電動送風機31を冷却した後、この電動送風機31の前側に位置する排気口から側方へと排気されて排気風となる。この排気風は、フィルタ119を通過しつつ下流側ダクト部39の接続風路部117へと流入し、この接続風路部117から電源室40内へと流入して、この電源室40内の電源部121を冷却する。そして、この電源室40を後方へと通過した排気風は、拡散室41へと流入する際に拡散され、各排気孔109から掃除機本体13の本体ケース25の外部へと分散排気される。 The air merged into the outflow air passage 178 is sucked from the outflow opening 194 through the communication port 63 into the electric blower 31 in the electric blower chamber from the communication air passage 115 of the downstream duct 39. After passing through the blower 31 and cooling the electric blower 31, it is exhausted from the exhaust port located on the front side of the electric blower 31 to the side to become exhaust air. The exhaust air flows through the filter 119 and flows into the connection air passage portion 117 of the downstream duct portion 39, and flows from the connection air passage portion 117 into the power supply chamber 40. The power supply unit 121 is cooled. The exhaust air that has passed through the power supply chamber 40 to the rear is diffused when flowing into the diffusion chamber 41, and is distributed and exhausted from the exhaust holes 109 to the outside of the main body case 25 of the cleaner body 13.
　掃除が終了すると、使用者が設定ボタン22を操作することで、制御手段がまず紫外線ランプ67を動作させて紫外線を所定時間照射した後、電動送風機31および紫外線ランプ67を停止させる。なお、紫外線ランプ67は、第２分離集塵部27に対して僅かな隙間のみを介して近接した状態であるため、紫外線の照射時間は数秒ないし数十秒程度と極めて短くても充分な除菌(殺菌)効果を得ることができる(図１０)。そして、紫外線ランプ67から照射した紫外線は、配置部66の下部の開口68および透過部材195aを介して窓部195を通過し、第２分離集塵部27内の流出風路部178に照射されてこの流出風路部178内を除菌(殺菌)するとともに、各接続開口192aを介して各分離室181内へと照射されてこれら分離室181内を除菌(殺菌)する。さらに、中央列L1に位置する分離室181内に照射された紫外線の一部は、これら分離室181を軸方向に通過して集塵ケース172の集塵ケース本体201内に照射され、この集塵ケース本体201内およびこの集塵ケース本体201の溜め部201b内に溜められた細塵(微細塵)を除菌(殺菌)する。 When the cleaning is completed, the user operates the setting button 22 so that the control unit first operates the ultraviolet lamp 67 to irradiate ultraviolet rays for a predetermined time, and then stops the electric blower 31 and the ultraviolet lamp 67. Since the ultraviolet lamp 67 is in close proximity to the second separated dust collecting part 27 through only a small gap, the ultraviolet irradiation time is about several seconds to several tens of seconds. A fungus (bactericidal) effect can be obtained (FIG. 10). Then, the ultraviolet rays irradiated from the ultraviolet lamp 67 pass through the window portion 195 through the opening 68 below the arrangement portion 66 and the transmission member 195a, and are irradiated to the outflow air passage portion 178 in the second separated dust collection portion 27. The inside of the outflow air passage portion 178 is sterilized (sterilized) and irradiated into each separation chamber 181 through each connection opening 192a to sterilize (sterilize) the inside of the separation chamber 181. Further, a part of the ultraviolet light irradiated into the separation chamber 181 located in the central row L1 passes through the separation chamber 181 in the axial direction and is irradiated into the dust collection case body 201 of the dust collection case 172. Fine dust (fine dust) stored in the dust case main body 201 and in the reservoir 201b of the dust collection case main body 201 is sterilized (sterilized).
　そして、所定量以上の塵埃が第１分離集塵部26および第２分離集塵部27の集塵ケース172に溜まった場合には、使用者は第１分離集塵部26および第２分離集塵部27をそれぞれ本体ケース25から取り外して塵埃を廃棄することが可能である。 When a predetermined amount or more of dust has accumulated in the dust collecting case 172 of the first separated dust collecting unit 26 and the second separated dust collecting unit 27, the user can use the first separated dust collecting unit 26 and the second separated dust collecting unit 172. The dust portions 27 can be removed from the main body case 25 to discard dust.
　このように、第１の実施形態によれば、電動送風機31の駆動により吸い込んだ含塵空気を旋回させて塵埃を遠心分離して捕集する第１分離集塵部26と第２分離集塵部27とを多段に接続するとともに、下流側に位置する第２分離集塵部27に対して紫外線ランプ67から紫外線を照射することにより、紫外線によって雑菌を効果的に除去できる。 As described above, according to the first embodiment, the first separated dust collecting unit 26 and the second separated dust collecting unit that rotate the dust-containing air sucked by the driving of the electric blower 31 to collect the dust by centrifugal separation. By connecting the unit 27 in multiple stages and irradiating the second separated dust collecting unit 27 located on the downstream side with ultraviolet rays from the ultraviolet lamp 67, germs can be effectively removed by ultraviolet rays.
　すなわち、第２分離集塵部27に流入する含塵空気は、第１分離集塵部26によって粗塵が遠心分離されたものであるため、第２分離集塵部27には粗塵が溜まることがない。そのため、第２分離集塵部27に紫外線ランプ67から紫外線を照射すると、この紫外線が粗塵によって遮断されたり拡散されたりすることがないので、紫外線によって雑菌を効果的に除去できる。 That is, since the dust-containing air flowing into the second separated dust collecting portion 27 is obtained by centrifuging coarse dust by the first separated dust collecting portion 26, the second separated dust collecting portion 27 accumulates coarse dust. There is nothing. Therefore, when the second separation dust collecting unit 27 is irradiated with ultraviolet rays from the ultraviolet lamp 67, the ultraviolet rays are not blocked or diffused by the coarse dust, so that germs can be effectively removed by the ultraviolet rays.
　特に、第１分離集塵部26には、主として粗塵が捕集されるため、使用者はこの第１分離集塵部26を頻繁に本体ケース25から取り外して内部の塵埃を廃棄するなどのメンテナンスを行うので、長期に亘って塵埃が内部に溜まりにくいものであり、雑菌などの繁殖が比較的少ない。それに対して、第２分離集塵部27は、殆どの塵埃を除去した第１分離集塵部26の後段に位置しているので、塵埃(細塵)が溜まりにくく、塵埃の廃棄などのメンテナンスを頻繁に行うものではなく、雑菌などが第１分離集塵部26よりも繁殖しやすい。すなわち、集塵手段28においては、後段(下流側)ほど捕集する塵埃量が少なく、頻繁なメンテナンスが必要とならずに、長期に亘って塵埃が溜まった状態となる傾向がある。したがって、下流側に位置する第２分離集塵部27に対して紫外線を照射して除菌(殺菌)することで、集塵手段28全体として雑菌が繁殖しにくくできる。 Particularly, since coarse dust is mainly collected in the first separated dust collecting portion 26, the user frequently removes the first separated dust collecting portion 26 from the main body case 25 and discards the dust inside. Since maintenance is performed, it is difficult for dust to accumulate inside for a long period of time, and propagation of germs and the like is relatively small. On the other hand, the second separated dust collecting portion 27 is located at the rear stage of the first separated dust collecting portion 26 from which most of the dust has been removed, so that dust (fine dust) is difficult to collect and maintenance such as dust disposal is performed. However, various germs and the like are more likely to propagate than the first separated dust collection unit 26. That is, in the dust collecting means 28, the amount of dust collected in the latter stage (downstream side) is small, and frequent maintenance is not required, and the dust tends to be accumulated over a long period of time. Therefore, by irradiating the second separated dust collecting portion 27 located on the downstream side with ultraviolet rays for sterilization (sterilization), it is possible for the dust collection means 28 as a whole to hardly propagate bacteria.
　また、紫外線ランプ67が、第２分離集塵部27の分離室181と、この分離室181により塵埃が分離された空気が通過する流出風路部178とに対して紫外線を照射することにより、分離室181により塵埃が遠心分離される直前の含塵空気と、各分離室181により塵埃が遠心分離された後の空気とのそれぞれを除菌(殺菌)でき、雑菌をより効果的に除去できる。特に、流出風路部178を通過する空気は、その下流側において雑菌が発生しやすい箇所がなく、電動送風機31に吸い込まれた後、排気されるので、この流出風路部178を通過する空気を除菌(殺菌)することにより、電動送風機31からの排気に異臭が生じたりすることを、より確実に防止できる。 Further, the ultraviolet lamp 67 irradiates the separation chamber 181 of the second separation dust collecting portion 27 and the outflow air passage portion 178 through which the air separated from the dust is passed by the separation chamber 181 with ultraviolet rays. Each of the dust-containing air immediately before the dust is centrifuged by the separation chamber 181 and the air after the dust is centrifuged by each separation chamber 181 can be sterilized (sterilized), so that germs can be removed more effectively. . In particular, the air passing through the outflow air passage portion 178 has no place where germs are likely to be generated downstream, and is sucked into the electric blower 31 and then exhausted. By sterilizing (sterilizing), it is possible to more reliably prevent the generation of a strange odor in the exhaust from the electric blower 31.
　なお、上記第１の実施形態において、紫外線ランプ67を点灯させるタイミングは任意に設定できる。 In the first embodiment, the timing for turning on the ultraviolet lamp 67 can be arbitrarily set.
　さらに、集塵手段28は、３段以上の多段の遠心分離部を備える構成としてもよい。この場合、紫外線ランプ67は、最上流の遠心分離部を除く少なくともいずれかの遠心分離部、すなわち下流側に位置する遠心分離部の少なくともいずれかに対して紫外線を照射するように構成することで、上記第１の実施形態と同様の作用効果を奏することができる。 Furthermore, the dust collecting means 28 may be configured to include a multi-stage centrifuge of three or more stages. In this case, the ultraviolet lamp 67 is configured to irradiate at least one of the centrifugal separation units excluding the most upstream centrifugal separation unit, that is, at least one of the centrifugal separation units located on the downstream side. The same operational effects as those of the first embodiment can be obtained.
　次に、第２の実施形態を図１１および図１２を参照して説明する。なお、上記第１の実施形態と同様の構成および作用については、同一符号を付してその説明を省略する。 Next, a second embodiment will be described with reference to FIGS. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
　この第２の実施形態は、上記第１の実施形態において、電動送風機31が、設定ボタン22の設定操作に応じて、本体部32内に収容された例えばマイコンなどの制御手段211により動作のオンオフなどが制御されるものである。 In the second embodiment, in the first embodiment, the electric blower 31 is turned on / off by the control means 211 such as a microcomputer housed in the main body 32 in accordance with the setting operation of the setting button 22. Are controlled.
　また、紫外線ランプ67は、風路Ｗの一部、本実施形態では第２分離集塵部27に対して紫外線を照射して除菌(殺菌)をするものであり、例えば制御手段211により消灯を含めた点灯状態が制御される。 Further, the ultraviolet lamp 67 sterilizes (sterilizes) a part of the air passage W by irradiating ultraviolet rays onto the second separated dust collecting portion 27 in this embodiment, and is turned off by the control means 211, for example. The lighting state including is controlled.
　次に、上記第２の実施形態の内部構造を説明する。 Next, the internal structure of the second embodiment will be described.
　制御手段211は、設定ボタン22からの操作信号が入力されるように構成されている。また、この制御手段211は、電源である商用交流電源ｅに先端部のプラグ部121aが接続された電源部121から給電を受けて動作可能であり、例えばトライアックなどの制御素子Trを介して、設定ボタン22からの操作信号に応じて電動送風機31の入力を設定するように構成されている。 The control means 211 is configured such that an operation signal from the setting button 22 is input. Further, the control means 211 can be operated by receiving power from a power supply unit 121 in which a plug unit 121a at the tip is connected to a commercial AC power source e that is a power source, for example, via a control element Tr such as a triac, The input of the electric blower 31 is set according to the operation signal from the setting button 22.
　さらに、この制御手段211は、計時手段としてのタイマＴおよび紫外線ランプ67と電気的に接続されており、この紫外線ランプ67の動作を制御可能となっている。なお、制御手段211が紫外線ランプ67を動作させるタイミングは、本実施形態においては、電動送風機31が動作している状態で設定ボタン22が操作されて制御手段211が電動送風機31を停止させる直前であり、タイマＴを介して計時した第１所定時間T1、紫外線ランプ67を動作させるように構成されている。この第１所定時間T1は、例えば電動送風機31の動作時間、すなわち今回の電動送風機31の起動から停止までの時間の長さに対応して可変設定することが好ましい。この第１所定時間T1の設定の際には、例えば予め設定された単数あるいは複数の閾値と電動送風機31の動作時間とを比較し、その動作時間と閾値との大小関係に対応して予め設定されたテーブルなどを参照して設定してもよいし、電動送風機31の動作時間を変数とする所定の数式などによって第１所定時間T1を算出して設定してもよい。いずれにしても、電動送風機31の動作時間が長いほど、第２分離集塵部27の集塵ケース172に多くの塵埃が溜まっていると考えられるため、電動送風機31の動作時間が長いほど第１所定時間T1を長く設定することが好ましい。 Further, the control means 211 is electrically connected to a timer T as a time measuring means and an ultraviolet lamp 67, and the operation of the ultraviolet lamp 67 can be controlled. In this embodiment, the timing at which the control unit 211 operates the ultraviolet lamp 67 is immediately before the setting unit 22 is operated and the control unit 211 stops the electric blower 31 while the electric blower 31 is operating. Yes, the ultraviolet lamp 67 is operated for a first predetermined time T1 measured via a timer T. The first predetermined time T1 is preferably variably set in accordance with, for example, the operation time of the electric blower 31, that is, the length of time from the start to the stop of the electric blower 31 this time. When the first predetermined time T1 is set, for example, a preset threshold value or threshold values are compared with the operating time of the electric blower 31 and set in advance corresponding to the magnitude relationship between the operating time and the threshold value. The first predetermined time T1 may be calculated and set by a predetermined mathematical formula using the operation time of the electric blower 31 as a variable. In any case, the longer the operating time of the electric blower 31 is, the more dust is accumulated in the dust collecting case 172 of the second separated dust collecting unit 27. 1 It is preferable to set the predetermined time T1 long.
　次に、上記第２の実施形態の作用を説明する。 Next, the operation of the second embodiment will be described.
　掃除の際には、使用者は、プラグ部121aを商用交流電源ｅに接続して電源部121により給電可能とした状態で、把持部21を把持して所望の設定ボタン22を操作することにより、電源部121から給電された制御手段211が制御素子Trを介して電動送風機31を位相角制御し、設定ボタン22の操作により設定された動作モードで電動送風機31を駆動させ、電動送風機31の駆動により生じた負圧によって、被掃除面に載置した床ブラシ19の先端などから、塵埃を空気とともに吸い込む。この含塵空気から各塵埃を分離捕集する過程は、上記第１の実施形態と同様であるため説明を省略する。 When cleaning, the user can operate the desired setting button 22 by holding the grip portion 21 in a state in which the plug portion 121a is connected to the commercial AC power source e and power can be supplied by the power source portion 121. The control means 211 fed from the power supply unit 121 controls the phase angle of the electric blower 31 via the control element Tr, drives the electric blower 31 in the operation mode set by the operation of the setting button 22, Due to the negative pressure generated by the drive, dust is sucked together with air from the tip of the floor brush 19 placed on the surface to be cleaned. Since the process of separating and collecting each dust from the dust-containing air is the same as that in the first embodiment, description thereof is omitted.
　そして、掃除が終了すると、使用者が設定ボタン22を操作することで、制御手段211がまず紫外線ランプ67を動作させて紫外線を照射した後、電動送風機31および紫外線ランプ67を停止させる。すなわち、電動送風機31の動作中に、設定ボタン22により停止操作がされたかどうか、すなわち電動送風機31のオフが設定されたかどうかを制御手段211が判断し(ステップ１)、このステップ１において、オフが設定されていないと判断した場合にはステップ１を繰り返し、オフが設定されたと判断した場合には、制御手段211がタイマＴを起動させるとともに紫外線ランプ67を点灯(起動)させる(ステップ２)。この後、制御手段211は、電動送風機31のオフが設定されたタイミング、すなわち紫外線ランプ67の点灯から第１所定時間T1が経過したかどうかを判断し(ステップ３)、第１所定時間T1が経過していないと判断した場合にはステップ３を繰り返し、第１所定時間T1が経過したと判断した場合には、制御手段211はタイマＴおよび紫外線ランプ67を停止させる(ステップ４)。なお、タイマＴは、この停止と同時にリセットしてもよいし、ステップ２において起動させる直前にリセットしてもよい。また、電動送風機31の停止のタイミングは、例えば紫外線ランプ67およびタイマＴの起動直前(ステップ１においてオフが設定されたと判断した直後)、紫外線ランプ67およびタイマＴの起動と同時、これら紫外線ランプ67およびタイマＴの動作中、これら紫外線ランプ67およびタイマＴの停止と同時、あるいは、これら紫外線ランプ67およびタイマＴの停止後など、任意のタイミングに設定することが可能である。 When the cleaning is completed, the user operates the setting button 22 so that the control unit 211 first operates the ultraviolet lamp 67 to irradiate ultraviolet rays, and then stops the electric blower 31 and the ultraviolet lamp 67. That is, during the operation of the electric blower 31, the control means 211 determines whether or not a stop operation has been performed by the setting button 22, that is, whether or not the electric blower 31 has been set off (step 1). Step 1 is repeated when it is determined that is not set, and when it is determined that OFF is set, the control means 211 starts the timer T and lights (starts) the ultraviolet lamp 67 (Step 2). . Thereafter, the control means 211 determines the timing at which the electric blower 31 is set to OFF, that is, whether or not the first predetermined time T1 has elapsed from the lighting of the ultraviolet lamp 67 (step 3). If it is determined that the time has not elapsed, step 3 is repeated. If it is determined that the first predetermined time T1 has elapsed, the control unit 211 stops the timer T and the ultraviolet lamp 67 (step 4). Note that the timer T may be reset at the same time as this stop, or may be reset immediately before starting in step 2. The timing of stopping the electric blower 31 is, for example, immediately before the start of the ultraviolet lamp 67 and the timer T (immediately after it is determined that OFF is set in step 1), simultaneously with the start of the ultraviolet lamp 67 and the timer T, the ultraviolet lamp 67 During the operation of the timer T, it is possible to set an arbitrary timing such as when the ultraviolet lamp 67 and the timer T are stopped or after the ultraviolet lamp 67 and the timer T are stopped.
　紫外線ランプ67から照射した紫外線は、配置部66の下部の開口68および透過部材195aを介して窓部195を通過し、第２分離集塵部27内の流出風路部178に照射されてこの流出風路部178内を除菌(殺菌)するとともに、各接続開口192aを介して各分離室181内へと照射されてこれら分離室181内を除菌(殺菌)する。さらに、分離室181内に照射された紫外線の一部は、これら分離室181を軸方向に通過して集塵ケース172に照射され、この集塵ケース172内およびこの集塵ケース172内に溜められた細塵(微細塵)を除菌(殺菌)する。 The ultraviolet rays emitted from the ultraviolet lamp 67 pass through the window portion 195 through the opening 68 and the transmission member 195a below the arrangement portion 66, and are emitted to the outflow air passage portion 178 in the second separated dust collecting portion 27. The inside of the outflow air passage portion 178 is sterilized (sterilized) and irradiated into each separation chamber 181 through each connection opening 192a to sterilize (sterilize) the inside of the separation chamber 181. Further, a part of the ultraviolet light irradiated in the separation chamber 181 passes through the separation chamber 181 in the axial direction and is irradiated to the dust collection case 172, and is stored in the dust collection case 172 and the dust collection case 172. Disinfect (sterilize) the fine dust produced.
　そして、所定量以上の塵埃が第１分離集塵部26および第２分離集塵部27の集塵ケース172に溜まった場合には、使用者は第１分離集塵部26および第２分離集塵部27をそれぞれ本体ケース25から取り外して塵埃を廃棄することが可能である。 When a predetermined amount or more of dust has accumulated in the dust collecting case 172 of the first separated dust collecting unit 26 and the second separated dust collecting unit 27, the user can use the first separated dust collecting unit 26 and the second separated dust collecting unit 172. The dust portions 27 can be removed from the main body case 25 to discard dust.
　このように、第２の実施形態によれば、制御手段211が、電動送風機31が動作している状態で設定ボタン22により電動送風機31のオフが設定されたタイミングから第１所定時間T1、紫外線ランプ67を動作させて風路Ｗの内部、本実施形態では第２分離集塵部27に紫外線を照射して除菌(殺菌)することにより、例えば電動送風機の排気風を循環させてその熱により除菌(殺菌)する場合と比較して低騒音化が可能となるとともに、紫外線ランプ67から照射される紫外線は、光触媒の酸化還元作用を発生させるためのものよりも強い、雑菌などのＤＮＡを破壊することにより除菌(殺菌)効果を有する除菌(殺菌)光であるので、短時間で除菌(殺菌)が可能になる。したがって、電気掃除機11の省電力化が可能になる。 As described above, according to the second embodiment, the control unit 211 performs the first predetermined time T1, the ultraviolet ray from the timing when the electric blower 31 is set off by the setting button 22 while the electric blower 31 is operating. The lamp 67 is operated to sterilize the inside of the air passage W, in the present embodiment, by irradiating ultraviolet rays to the second separated dust collecting portion 27, for example, to circulate the exhaust air of an electric blower and to generate heat. Compared with the case of sterilization (sterilization) by the use of the above, it is possible to reduce the noise, and the ultraviolet rays irradiated from the ultraviolet lamp 67 are stronger than those for generating the oxidation-reduction action of the photocatalyst. Since the light is sterilization (sterilization) light having a sterilization (sterilization) effect by destroying, the sterilization (sterilization) can be performed in a short time. Therefore, power saving of the vacuum cleaner 11 can be achieved.
　また、電動送風機31は、長時間動作させるほど第２分離集塵部27での塵埃の捕集量が増え、風路Ｗ(第２分離集塵部27)内の雑菌の量が増えると考えられるため、紫外線ランプ67を動作させる第１所定時間T1を、直前の電動送風機31の動作時間に対応させて変化させる、具体的には、電動送風機31の動作時間が長いほど第１所定時間T1を長く設定することにより、風路Ｗ(第２分離集塵部27)をより効果的に除菌(殺菌)できる。 In addition, the electric blower 31 is considered to increase the amount of dust collected in the second separated dust collecting unit 27 and to increase the amount of germs in the air passage W (second separated dust collecting unit 27) as it is operated for a long time. Therefore, the first predetermined time T1 for operating the ultraviolet lamp 67 is changed corresponding to the operation time of the previous electric blower 31. Specifically, the longer the operation time of the electric blower 31 is, the first predetermined time T1 is. Is set longer, the air passage W (second separated dust collecting portion 27) can be sterilized (sterilized) more effectively.
　次に、第３の実施形態を図１３を参照して説明する。なお、上記第２の実施形態と同様の構成および作用については、同一符号を付してその説明を省略する。 Next, a third embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to the said 2nd Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
　この第３の実施形態は、上記第２の実施形態の制御に代えて、制御手段211が紫外線ランプ67を、電動送風機31に商用交流電源ｅから給電可能となったタイミング、換言すればプラグ部121aを商用交流電源ｅに接続したタイミング(プラグイン)から所定時間T2動作させるものである。 In this third embodiment, instead of the control of the second embodiment, the control means 211 is able to supply the ultraviolet lamp 67 to the electric blower 31 from the commercial AC power source e, in other words, the plug portion. T2 is operated for a predetermined time from the timing (plug-in) at which 121a is connected to the commercial AC power source e.
　なお、制御手段211は、プラグ部121aを商用交流電源ｅに接続した上記のタイミングから所定時間T2が経過する前に設定ボタン22により電動送風機31のオンが設定された場合には、この電動送風機31の動作中も継続して紫外線ランプ67を動作させる。すなわち、制御手段211は、電動送風機31を起動させる操作がされたか否かに拘らず、プラグ部121aを商用交流電源ｅに接続した上記のタイミングから所定時間T2が経過するまで紫外線ランプ67は動作を継続する。 In addition, the control means 211 is connected to the electric blower 31 when the electric blower 31 is turned on by the setting button 22 before the predetermined time T2 has elapsed from the above timing when the plug unit 121a is connected to the commercial AC power source e. The ultraviolet lamp 67 is continuously operated during the operation of 31. That is, the control unit 211 operates the ultraviolet lamp 67 until a predetermined time T2 elapses from the above timing when the plug unit 121a is connected to the commercial AC power source e, regardless of whether or not an operation for starting the electric blower 31 is performed. Continue.
　すなわち、図１３のフローチャートに示すように、制御手段211は、プラグ部121aが商用交流電源ｅに接続されたかどうか(プラグインされたかどうか)を判断する(ステップ11)。このステップ11において、プラグ部121aが商用交流電源ｅに接続されていない(プラグインされていない)と判断した場合には、ステップ11を繰り返す。また、このステップ11において、プラグ部121aが商用交流電源ｅに接続された(プラグインされた)と判断した場合には、制御手段211は、タイマＴを起動させるとともに紫外線ランプ67を点灯(起動)させる(ステップ12)。 That is, as shown in the flowchart of FIG. 13, the control unit 211 determines whether or not the plug unit 121a is connected to the commercial AC power source e (whether or not it is plugged in) (step 11). If it is determined in step 11 that the plug unit 121a is not connected to the commercial AC power source e (not plugged in), step 11 is repeated. If it is determined in step 11 that the plug unit 121a is connected to the commercial AC power source e (plugged in), the control unit 211 activates the timer T and turns on the ultraviolet lamp 67 (activates the activation). (Step 12).
　次いで、制御手段211は、プラグ部121aが商用交流電源ｅに接続されたタイミング、すなわち紫外線ランプ67の点灯から所定時間T2が経過したかどうかを判断する(ステップ13)。このステップ13において、所定時間T2が経過したと判断した場合には、制御手段211はタイマＴおよび紫外線ランプ67を停止させ(ステップ14)、設定ボタン22により起動操作、すなわち電動送風機31のオンが設定されたかどうかを判断する(ステップ15)。このステップ15において、オンが設定されていないと判断した場合には、ステップ15を繰り返し、オンが設定されたと判断した場合には、電動送風機31を設定ボタン22により設定された動作モードで起動させる(ステップ16)。 Next, the control means 211 determines the timing when the plug unit 121a is connected to the commercial AC power source e, that is, whether or not a predetermined time T2 has elapsed since the ultraviolet lamp 67 is turned on (step 13). If it is determined in step 13 that the predetermined time T2 has elapsed, the control unit 211 stops the timer T and the ultraviolet lamp 67 (step 14), and the setting button 22 activates the operation, that is, the electric blower 31 is turned on. It is determined whether it has been set (step 15). If it is determined in this step 15 that ON is not set, step 15 is repeated. If it is determined that ON is set, the electric blower 31 is activated in the operation mode set by the setting button 22. (Step 16).
　一方、ステップ13において、所定時間T2が経過していないと判断した場合には、制御手段211は、設定ボタン22により起動操作、すなわち電動送風機31のオンが設定されたかどうかを判断する(ステップ17)。このステップ17において、オンが設定されていないと判断した場合には、ステップ13に戻り、オンが設定されたと判断した場合には、電動送風機31を設定ボタン22により設定された動作モードで起動させる(ステップ18)。 On the other hand, when it is determined in step 13 that the predetermined time T2 has not elapsed, the control unit 211 determines whether or not the setting button 22 has set the start operation, that is, whether the electric blower 31 is turned on (step 17). ). If it is determined in step 17 that ON is not set, the process returns to step 13. If it is determined that ON is set, the electric blower 31 is activated in the operation mode set by the setting button 22. (Step 18).
　このステップ18の後、制御手段211は、プラグ部121aが商用交流電源ｅに接続されたタイミング、すなわち紫外線ランプ67の点灯から所定時間T2が経過したかどうかを判断し(ステップ19)、所定時間T2が経過していないと判断した場合には、ステップ19を繰り返し、所定時間T2が経過したと判断した場合には、タイマＴおよび紫外線ランプ67を停止させる(ステップ20)。なお、ステップ19において、所定時間T2が経過する前に設定ボタン22によって電動送風機31のオフが設定された場合には、制御手段211は、例えば紫外線ランプ67および電動送風機31をともに直ちに停止させてもよいし、プラグ部121aが商用交流電源ｅに接続されたタイミングから所定時間T2が経過した後に紫外線ランプ67とともに電動送風機31を停止させてもよいし、電動送風機31を停止させた後、プラグ部121aが商用交流電源ｅに接続されたタイミングから所定時間T2が経過するまで紫外線ランプ67の点灯を継続させてもよい。また、タイマＴは、ステップ14あるいはステップ20の停止と同時にリセットしてもよいし、ステップ12において起動させる直前にリセットしてもよい。 After this step 18, the control means 211 determines the timing at which the plug unit 121a is connected to the commercial AC power source e, that is, whether or not a predetermined time T2 has elapsed since the lighting of the ultraviolet lamp 67 (step 19). When it is determined that T2 has not elapsed, step 19 is repeated, and when it is determined that the predetermined time T2 has elapsed, the timer T and the ultraviolet lamp 67 are stopped (step 20). In step 19, when the electric blower 31 is set off by the setting button 22 before the predetermined time T2 elapses, the control unit 211 immediately stops both the ultraviolet lamp 67 and the electric blower 31, for example. Alternatively, the electric blower 31 may be stopped together with the ultraviolet lamp 67 after a predetermined time T2 has elapsed from the timing at which the plug unit 121a is connected to the commercial AC power source e, or the electric blower 31 is stopped and then the plug The lighting of the ultraviolet lamp 67 may be continued until a predetermined time T2 elapses from the timing when the unit 121a is connected to the commercial AC power source e. The timer T may be reset simultaneously with the stop of step 14 or step 20, or may be reset immediately before being started in step 12.
　以上説明した第３の実施形態によれば、制御手段211が、電動送風機31に商用交流電源ｅから給電可能となったタイミング、すなわちプラグ部121aが商用交流電源ｅに接続されたタイミングから紫外線ランプ67を所定時間T2動作させて風路Ｗ、本実施形態では第２分離集塵部27に紫外線を照射して除菌(殺菌)することにより、例えば電動送風機の排気風を循環させてその熱により除菌(殺菌)する場合と比較して低騒音化が可能となるとともに、紫外線ランプ67から照射される紫外線は、光触媒の酸化還元作用を発生させるためのものよりも強い、雑菌などのＤＮＡを破壊することにより除菌(殺菌)効果を有する除菌(殺菌)光であるので、短時間で除菌(殺菌)が可能になる。したがって、電気掃除機11の省電力化が可能になる。 According to the third embodiment described above, the ultraviolet ray lamp starts from the timing when the control unit 211 can supply power to the electric blower 31 from the commercial AC power source e, that is, the timing when the plug part 121a is connected to the commercial AC power source e. 67 is operated for T2 for a predetermined time to sterilize by irradiating ultraviolet rays to the air passage W, in this embodiment the second separated dust collecting portion 27, for example, by circulating the exhaust air of an electric blower and its heat. Compared with the case of sterilization (sterilization) by the use of the above, it is possible to reduce the noise, and the ultraviolet rays irradiated from the ultraviolet lamp 67 are stronger than those for generating the oxidation-reduction action of the photocatalyst. Since the light is sterilization (sterilization) light having a sterilization (sterilization) effect by destroying, the sterilization (sterilization) can be performed in a short time. Therefore, power saving of the vacuum cleaner 11 can be achieved.
　また、例えば前回掃除をしてから今回の掃除まで期間が開いている場合などには、風路Ｗ(第２分離集塵部27)の内部に雑菌が増殖していることが考えられるため、掃除を開始する前、すなわち電動送風機31が起動する前に紫外線ランプ67により除菌(殺菌)することで、電動送風機31の起動時の排気に異臭が発生することを確実に防止できる。 In addition, for example, when the period from the previous cleaning to the current cleaning is open, it is considered that germs are growing inside the air passage W (second separated dust collecting portion 27). By performing sterilization (sterilization) with the ultraviolet lamp 67 before starting the cleaning, that is, before the electric blower 31 is started, it is possible to reliably prevent the generation of a strange odor in the exhaust when the electric blower 31 is started.
　さらに、プラグ部121aが商用交流電源ｅに接続されたタイミングから所定時間T2が経過する前に設定ボタン22により電動送風機31のオンが設定された場合にはこの電動送風機31の動作中も継続して紫外線ランプ67を動作させることにより、設定ボタン22を操作しているにも拘らず電動送風機31が起動しないなどの不具合が生じることがないとともに、風路Ｗ(第２分離集塵部27)を確実に除菌(殺菌)できる。 Furthermore, when the electric blower 31 is set to ON by the setting button 22 before the predetermined time T2 has elapsed from the timing when the plug unit 121a is connected to the commercial AC power source e, the electric blower 31 continues during operation. By operating the ultraviolet lamp 67, there is no problem that the electric blower 31 does not start even though the setting button 22 is operated, and the air passage W (second separated dust collecting portion 27) Can be surely sterilized (sterilized).
　なお、上記第２および第３の実施形態を組み合わせてもよい。すなわち、電気掃除機11の起動前には上記第３の実施形態の制御を行い、駆動中の電気掃除機11を停止させる際には上記第２の実施形態の制御を行うようにしてもよい。このとき、例えば第３の実施形態のステップ19において、所定時間である第２所定時間T2が経過する前に設定ボタン22によって電動送風機31のオフが設定された場合には、制御手段211は、例えばタイマＴをリセットし、上記第２の実施形態のステップ２に進んでもよい。 Note that the second and third embodiments may be combined. That is, the control of the third embodiment may be performed before the vacuum cleaner 11 is started, and the control of the second embodiment may be performed when the driven vacuum cleaner 11 is stopped. . At this time, for example, in step 19 of the third embodiment, when the electric blower 31 is set off by the setting button 22 before the second predetermined time T2, which is a predetermined time, has passed, the control unit 211 For example, the timer T may be reset and the process may proceed to step 2 of the second embodiment.
　そして、上記第２および第３の実施形態の少なくともいずれかによれば、電動送風機31の駆動により吸い込んだ含塵空気を旋回させて塵埃を遠心分離して捕集する第１分離集塵部26と第２分離集塵部27とを多段に接続するとともに、下流側に位置する第２分離集塵部27に対して紫外線ランプ67から紫外線を照射することにより、紫外線によって雑菌を効果的に除去できる。 According to at least one of the second and third embodiments, the first separated dust collecting unit 26 that swirls the dust-containing air sucked by the driving of the electric blower 31 and collects the dust by centrifugal separation. And the second separated dust collecting portion 27 are connected in multiple stages, and the second separated dust collecting portion 27 located on the downstream side is irradiated with ultraviolet rays from an ultraviolet lamp 67, thereby effectively removing germs by ultraviolet rays. it can.
　すなわち、第２分離集塵部27に流入する含塵空気は、第１分離集塵部26によって粗塵が遠心分離されたものであるため、第２分離集塵部27には粗塵が溜まることがない。そのため、第２分離集塵部27に紫外線ランプ67から紫外線を照射すると、この紫外線が粗塵によって遮断されたり拡散されたりすることがないので、紫外線によって雑菌を効果的に除去できる。 That is, since the dust-containing air flowing into the second separated dust collecting portion 27 is obtained by centrifuging coarse dust by the first separated dust collecting portion 26, the second separated dust collecting portion 27 accumulates coarse dust. There is nothing. Therefore, when the second separation dust collecting unit 27 is irradiated with ultraviolet rays from the ultraviolet lamp 67, the ultraviolet rays are not blocked or diffused by the coarse dust, so that germs can be effectively removed by the ultraviolet rays.
　特に、第１分離集塵部26には、主として粗塵が捕集されるため、使用者はこの第１分離集塵部26を頻繁に本体ケース25から取り外して内部の塵埃を廃棄するなどのメンテナンスを行うので、長期に亘って塵埃が内部に溜まりにくいものであり、雑菌などの繁殖が比較的少ない。それに対して、第２分離集塵部27は、殆どの塵埃を除去した第１分離集塵部26の後段に位置しているので、塵埃(細塵)が溜まりにくく、塵埃の廃棄などのメンテナンスを頻繁に行うものではなく、雑菌などが第１分離集塵部26よりも繁殖しやすい。すなわち、集塵手段28においては、後段(下流側)ほど捕集する塵埃量が少なく、頻繁なメンテナンスが必要とならずに、長期に亘って塵埃が溜まった状態となる傾向がある。したがって、下流側に位置する第２分離集塵部27に対して紫外線を照射して除菌(殺菌)することで、集塵手段28全体として雑菌が繁殖しにくくできる。 Particularly, since coarse dust is mainly collected in the first separated dust collecting portion 26, the user frequently removes the first separated dust collecting portion 26 from the main body case 25 and discards the dust inside. Since maintenance is performed, it is difficult for dust to accumulate inside for a long period of time, and propagation of germs and the like is relatively small. On the other hand, the second separated dust collecting portion 27 is located at the rear stage of the first separated dust collecting portion 26 from which most of the dust has been removed, so that dust (fine dust) is difficult to collect and maintenance such as dust disposal is performed. However, various germs and the like are more likely to propagate than the first separated dust collection unit 26. That is, in the dust collecting means 28, the amount of dust collected in the latter stage (downstream side) is small, and frequent maintenance is not required, and the dust tends to be accumulated over a long period of time. Therefore, by irradiating the second separated dust collecting portion 27 located on the downstream side with ultraviolet rays for sterilization (sterilization), it is possible for the dust collection means 28 as a whole to hardly propagate bacteria.
　また、紫外線ランプ67が、第２分離集塵部27の分離室181と、この分離室181により塵埃が分離された空気が通過する流出風路部178とに対して紫外線を照射することにより、分離室181により塵埃が遠心分離される直前の含塵空気と、各分離室181により塵埃が遠心分離された後の空気とのそれぞれを除菌(殺菌)でき、雑菌をより効果的に除去できる。特に、流出風路部178を通過する空気は、その下流側において雑菌が発生しやすい箇所がなく、電動送風機31に吸い込まれた後、排気されるので、この流出風路部178を通過する空気を除菌(殺菌)することにより、電動送風機31からの排気に異臭が生じたりすることを、より確実に防止できる。 Further, the ultraviolet lamp 67 irradiates the separation chamber 181 of the second separation dust collecting portion 27 and the outflow air passage portion 178 through which the air separated from the dust is passed by the separation chamber 181 with ultraviolet rays. Each of the dust-containing air immediately before the dust is centrifuged by the separation chamber 181 and the air after the dust is centrifuged by each separation chamber 181 can be sterilized (sterilized), so that germs can be removed more effectively. . In particular, the air passing through the outflow air passage portion 178 has no place where germs are likely to be generated downstream, and is sucked into the electric blower 31 and then exhausted. By sterilizing (sterilizing), it is possible to more reliably prevent the generation of a strange odor in the exhaust from the electric blower 31.
　なお、上記第２および第３の実施形態において、第１分離集塵部26および第２分離集塵部27は、含塵空気から塵埃を捕集できれば、任意の構成とすることができる。 In the second and third embodiments, the first separated dust collecting unit 26 and the second separated dust collecting unit 27 can have any configuration as long as dust can be collected from the dust-containing air.
　また、紫外線ランプ67は、風路Ｗ中の任意の箇所に紫外線を照射する構成とすることができる。 Further, the ultraviolet lamp 67 can be configured to irradiate ultraviolet rays at any location in the air passage W.
　また、上記各実施形態において、第２分離集塵部27は、合成樹脂により成形している場合、紫外線ランプ67から照射された紫外線により劣化しないように、紫外線が当たる箇所にめっきを施すなどの対策をしてもよいし、例えば合成樹脂以外でも、紫外線により劣化しない(劣化しにくい)部材を用いて設けてもよい。 Moreover, in each said embodiment, when the 2nd separated dust collection part 27 is shape | molded with the synthetic resin, it plated to the location which ultraviolet rays hit so that it may not deteriorate with the ultraviolet rays irradiated from the ultraviolet lamp 67 etc. A countermeasure may be taken, and for example, a material other than a synthetic resin may be provided using a member that is not deteriorated (not easily deteriorated) by ultraviolet rays.
