以下に、本発明をその実施の形態を示す図面に基づき説明する。
（実施の形態１）
図１は、本発明に係る真空掃除機の実施の形態１の外観を示し、一部を透視して示す斜視図であり、図２は、図１に示す真空掃除機のオゾン及び空気の流通経路を示す説明図である。
この真空掃除機１０Ａは、吸込形ファン６０を内蔵する真空掃除機の本体２０と、床面上を滑りつつ塵埃を吸い込む吸込口３１を有する吸込ヘッド３０と、真空掃除機の本体２０及び吸込ヘッド３０間を接続し、一部に折り曲げ自在なフレキシブルホースを有する管路４０とを備えている。管路４０の中途には、ユーザが保持する為の直管部が設けてあり、その直管部には、真空掃除機１０Ａをオン／オフする操作スイッチ４３が設けてある。 Hereinafter, the present invention will be described with reference to the drawings illustrating embodiments thereof.
(Embodiment 1)
FIG. 1 is a perspective view showing the appearance of a first embodiment of a vacuum cleaner according to the present invention, with a partial see-through, and FIG. 2 is a flow diagram of ozone and air in the vacuum cleaner shown in FIG. It is explanatory drawing which shows a path | route.
The vacuum cleaner 10A includes a main body 20 of a vacuum cleaner having a suction fan 60, a suction head 30 having a suction port 31 for sucking dust while sliding on the floor, and a main body 20 and a suction head of the vacuum cleaner. 30 and a conduit 40 having a flexible hose that can be bent in part. In the middle of the pipe line 40, a straight pipe part for holding by the user is provided, and an operation switch 43 for turning on / off the vacuum cleaner 10A is provided in the straight pipe part.

管路４０の内部は、排気通路４１と吸気通路４２とが分離形成されている。排気通路４１及び吸気通路４２は、管路４０内に別途のフレキシブルホースを配置したり、管路４０内に別途２本の流通路を形成したりすることにより設けることが出来る。
真空掃除機の本体２０に内設された吸込形ファン６０は、弱、中、強の３段階で作動出来るようになっている。吸込形ファン６０は、その吸込口が図示しない集塵用フィルタを介して吸気通路４２と接続され、その排出口が排気通路４１と接続され、図２に示すように、空気（排気）が、排気通路４１、吸込口３１、吸気通路４２及び吸込形ファン６０の経路で循環するようになっている。集塵用フィルタは、吸気を濾過して吸気に含まれる塵埃を捕集する。 Inside the conduit 40, an exhaust passage 41 and an intake passage 42 are separately formed. The exhaust passage 41 and the intake passage 42 can be provided by disposing a separate flexible hose in the conduit 40 or by forming two separate flow passages in the conduit 40.
The suction fan 60 provided in the main body 20 of the vacuum cleaner can be operated in three stages: weak, medium and strong. The suction fan 60 has a suction port connected to the intake passage 42 via a dust collecting filter (not shown), and a discharge port connected to the exhaust passage 41. As shown in FIG. The exhaust passage 41, the suction port 31, the intake passage 42, and the suction fan 60 are circulated through the passage. The dust collection filter collects dust contained in the intake air by filtering the intake air.

吸込ヘッド３０の上面には、オゾンを発生させるオゾン発生器５０が着設されている。オゾン発生器５０には、グラス又はセラミックス放電管の内部に高電圧を印加して、オゾンを発生させる無声放電方式、又は酸素に紫外線ランプ等から紫外線を照射して、オゾンを発生させる光化学反応方式を選択することが出来る。   An ozone generator 50 that generates ozone is attached to the upper surface of the suction head 30. The ozone generator 50 is a silent discharge system that generates ozone by applying a high voltage inside a glass or ceramic discharge tube, or a photochemical reaction system that generates ozone by irradiating oxygen from an ultraviolet lamp or the like to generate oxygen. Can be selected.

オゾン発生器５０の出口は、排気通路４１の末端近くに形設されたベンチュリ管５２の狭小部に、連絡管５４により接続されている。ベンチュリ管５２は、図３に模式的に示すように、排気通路４１の中途に設けられた狭小部で空気の流速が増加することで発生した負圧により、オゾン発生器５０からのオゾンが排気通路４１へ吸い出されるように構成されており、霧吹きと同様の原理で作用する。排気通路４１へ吸い出されたオゾンは、排気と共に吸込口３１へ吐出される。
真空掃除機１０Ａは、排気循環式及びベンチュリ管５２を採用することにより、吸込形ファン６０の容量を従来に比べて１／５〜１／３に低減させることが出来るので、騒音、消費電力及び微細な塵の排出量を低減させることが出来る。 The outlet of the ozone generator 50 is connected to a narrow portion of a venturi pipe 52 formed near the end of the exhaust passage 41 by a connecting pipe 54. As schematically shown in FIG. 3, the venturi tube 52 exhausts ozone from the ozone generator 50 due to the negative pressure generated by the increase in the air flow velocity in the narrow portion provided in the middle of the exhaust passage 41. It is configured to be sucked out into the passage 41 and operates on the same principle as spraying. The ozone sucked into the exhaust passage 41 is discharged to the suction port 31 together with the exhaust.
Since the vacuum cleaner 10A can reduce the capacity of the suction fan 60 to 1/5 to 1/3 of the conventional type by adopting the exhaust circulation type and the venturi pipe 52, noise, power consumption and The amount of fine dust discharged can be reduced.

以下に、このような構成の真空掃除機１０Ａの動作を説明する。
ユーザは、先ず、掃除しようとする例えばカーペット、布団、ソファ−等に吸込ヘッド３０の吸込口３１を持って行き、管路４０の直管部に設けられた操作スイッチ４３を操作して、吸込形ファン６０及びオゾン発生器５０を起動させる。
これにより、オゾン発生器５０からオゾンが発生すると共に、吸込形ファン６０が回転駆動することにより吸気通路４２には吸引力が発生して、吸込口３１で空気が吸い込まれる。吸い込まれた空気は、吸気通路４２、吸込形ファン６０の排出口及び排気通路４１を経由して、吸込ヘッド３０の吸込口３１に排出され、排出された空気（排気）は、再度、同様に吸い込まれ、吸気通路４２、吸込形ファン６０の排出口、排気通路４１及び吸込口３１の経路で循環する。また、上述した集塵用フィルタで塵埃が除去される。 Below, operation | movement of 10 A of vacuum cleaners of such a structure is demonstrated.
First, the user brings the suction port 31 of the suction head 30 to a carpet, a futon, a sofa, etc. to be cleaned, and operates the operation switch 43 provided in the straight pipe portion of the pipe line 40 to perform suction. The fan 60 and the ozone generator 50 are activated.
As a result, ozone is generated from the ozone generator 50, and suction force is generated in the intake passage 42 when the suction fan 60 is rotationally driven, so that air is sucked through the suction port 31. The sucked air is discharged to the suction port 31 of the suction head 30 via the intake passage 42, the discharge port of the suction fan 60 and the exhaust passage 41, and the discharged air (exhaust) is again in the same manner. The air is sucked and circulates through the paths of the intake passage 42, the discharge port of the suction fan 60, the exhaust passage 41 and the suction port 31. Further, dust is removed by the dust collecting filter described above.

このとき、排気通路４１を流れる空気（排気）の流速が、ベンチュリ管５２の狭小部により上昇することで、ベンチュリ管５２の狭小部及び連絡管５４には圧力降下が発生する。これによる負圧により、オゾン発生器５０で発生したオゾンが、出口から連絡管５４を通じてベンチュリ管５２内へ吸い出されて、排気通路４１の末端部を通じて吸込口３１に吐出され供給される。
このように、吸込形ファン６０が作動している期間は、継続的に吸込口３１にオゾンが吐出供給されるので、吸込口３１に接する部分は、オゾンに効率良く曝され、殺菌消毒作用を得ることが出来る。 At this time, the flow velocity of the air (exhaust gas) flowing through the exhaust passage 41 rises due to the narrow portion of the venturi tube 52, so that a pressure drop occurs in the narrow portion of the venturi tube 52 and the communication tube 54. Due to this negative pressure, ozone generated by the ozone generator 50 is sucked into the venturi 52 through the connecting pipe 54 from the outlet, and is discharged and supplied to the suction port 31 through the end portion of the exhaust passage 41.
In this way, during the period when the suction fan 60 is operating, ozone is continuously discharged and supplied to the suction port 31, so that the portion in contact with the suction port 31 is efficiently exposed to ozone and has a sterilizing and disinfecting action. Can be obtained.

本発明に係る真空掃除機の実施の形態２のその他の構成は、図１，２に示す実施の形態１の構成と同様であるので、同一箇所には同一符号を付して、説明を省略する。 On the upper surface of the suction head 30, an ozone generator 50 that generates ozone and a fan 100 that pushes out the ozone generated by the ozone generator 50 and discharges it into the suction port 31 are attached. The fan 100 is small, and the power source thereof can be a storage battery that is charged independently or a power source unit of the main body 20. Moreover, the ozone generator 50 and the fan 100 can select either a separated configuration or an integrated configuration.
The other configuration of the second embodiment of the vacuum cleaner according to the present invention is the same as the configuration of the first embodiment shown in FIGS. To do.

以下に、このような構成の真空掃除機１０Ｂの動作を説明する。
ユーザは、先ず、掃除しようとする例えばカーペット、布団、ソファ−等に吸込ヘッド３０の吸込口３１を持って行き、吸気通路４２ａの直管部に設けられた操作スイッチ４３（図１）を操作して、吸込形ファン６０、オゾン発生器５０及びファン１００を起動させる。
これにより、オゾン発生器５０からオゾンが発生すると共に、吸込形ファン６０が回転駆動することにより吸気通路４２ａには吸引力が発生して、吸込口３１で空気が吸い込まれる。吸い込まれた空気は、吸気通路４２ａ、及び吸込形ファン６０の排出口を経由して、排気口２２から排出される。また、上述した集塵用フィルタで塵埃が除去される。 Below, operation | movement of the vacuum cleaner 10B of such a structure is demonstrated.
First, the user brings the suction port 31 of the suction head 30 to a carpet, a futon, a sofa or the like to be cleaned, and operates the operation switch 43 (FIG. 1) provided in the straight pipe portion of the intake passage 42a. Then, the suction fan 60, the ozone generator 50, and the fan 100 are started.
As a result, ozone is generated from the ozone generator 50, and suction force is generated in the intake passage 42 a when the suction fan 60 is driven to rotate, and air is sucked in through the suction port 31. The sucked air is discharged from the exhaust port 22 via the intake passage 42 a and the discharge port of the suction fan 60. Further, dust is removed by the dust collecting filter described above.

このとき、オゾン発生器５０が発生させたオゾンは、ファン１００による送風で押し出され、図４に示すように、吸込口３１に吐出され供給される。送風により、吸込口３１に接する部分に付着している塵埃及び異物が浮き上がり、吸込形ファン６０の吸引力により、上述した集塵用フィルタ内に誘導されるので、吸込形ファン６０の容量を小さくすることができる。また、吸込口３１と接する部分は、オゾンに曝されるので殺菌消毒作用を期待することが出来る。   At this time, the ozone generated by the ozone generator 50 is pushed out by blowing air from the fan 100 and is discharged and supplied to the suction port 31 as shown in FIG. The dust and foreign matter adhering to the portion in contact with the suction port 31 are lifted by the air blowing, and are guided into the dust collecting filter by the suction force of the suction fan 60. Therefore, the capacity of the suction fan 60 is reduced. can do. Moreover, since the part which touches the suction inlet 31 is exposed to ozone, it can expect a disinfection action.

以上のように、真空掃除機１０Ｂは、吸込形ファン６０の容量を小さくすることが出来るので、騒音及び消費電力を低減させることが出来る。また、オゾンが吸込ヘッド３０の吸込口３１に噴出（吐出）されるので、吸込口３１と接する部分は、オゾンに効率良く曝され殺菌消毒効果が向上する。
尚、本実施の形態２では、非循環式の真空掃除機にオゾン発生器５０及びファン１００を適用した形態を説明したが、実施の形態１で説明した排気循環式の真空掃除機に、ベンチュリ管５２に代えてファン１００を適用することも可能である。この場合、オゾン発生器５０が発生させたオゾンを、ファン１００の送風により排気通路４２の一部を通じて吸込口３１へ吐出させるように構成する。 As described above, since the vacuum cleaner 10B can reduce the capacity of the suction fan 60, noise and power consumption can be reduced. Further, since ozone is ejected (discharged) to the suction port 31 of the suction head 30, the portion in contact with the suction port 31 is efficiently exposed to ozone and the sterilization and sterilization effect is improved.
In the second embodiment, the embodiment in which the ozone generator 50 and the fan 100 are applied to a non-circulating vacuum cleaner has been described. However, in the exhaust circulation vacuum cleaner described in the first embodiment, a venturi is used. It is also possible to apply the fan 100 instead of the tube 52. In this case, the ozone generated by the ozone generator 50 is discharged to the suction port 31 through a part of the exhaust passage 42 by blowing air from the fan 100.
