Description

【0001】
【発明の属する技術分野】
本発明は電気掃除機に関するものであり、特に金属への紫外線照射により発生する光電子を利用したマイナス粒子発生装置を備える電気掃除機に関するものである。
【0002】
【従来の技術】
従来の電気掃除機は、ファンにより吸引した空気を電気掃除機本体部の後方から排出しており、ファンの温度上昇に伴い排出される空気も少なからず温度が上昇する等の理由で、電気掃除機を作動させる室内では不快感を伴うことが多かった。
【0003】
また、電気掃除機本体部の吸塵室内には室内で発生する塵、ほこり等が蓄えられるために、吸塵室内でカビが増殖する等の衛生上の課題を有していた。
【0004】
【発明が解決しようとする課題】
前述の様に従来の電気掃除機は、電気掃除機を作動させる室内に不快感を伴うことが多く、また吸塵室内でカビが増殖する等の衛生上の課題も有している。
【0005】
本発明はこれらの課題を解決するもので、運転させた際に室内雰囲気を不快にさせることのない電気掃除機の提供を目的とする。
【0006】
【課題を解決するための手段】
前記従来技術の課題を解決するために本発明の電気掃除機は、吸塵室とファンを内蔵しホース接続孔を設けた電気掃除機の本体部において、前記本体部内のファンの排気経路中にマイナス粒子発生装置を備え、前記マイナス粒子発生装置は、光電子発生材と前記光電子発生材の表面に紫外線を照射するための紫外線源とから構成した。
【0007】
そして、電気掃除機本体部の排気経路中にマイナス粒子発生装置を備えたので、掃除機から排出される空気にはマイナスイオンが含まれることとなる。一般にマイナスイオンは人体に対してリラックス効果が有ると言われており、本発明の電気掃除機を運転した室内は、従来の電気掃除機を運転した場合と比べて快適になる。特に、本発明の電気掃除機が備えるマイナス粒子発生装置は、金属表面に紫外線を照射して得られる光電子を利用したものであるから、人体に有害なオゾンを原理的に発生しないと言う特徴を有する。
【0008】
【発明の実施の形態】
請求項1に記載した発明は、吸塵室とファンを内蔵しホース接続孔を設けた電気掃除機の本体部において、前記本体部内のファンの排気経路中にマイナス粒子発生装置を備え、前記マイナス粒子発生装置は、光電子発生材と前記光電子発生材の表面に紫外線を照射するための紫外線源とからなる構成とした。
【0009】
ファンの排気経路中にマイナス粒子発生装置を備えることにより、電気掃除機の排出空気中にはマイナス粒子が付加されることとなる。一般的にマイナス粒子には人体に対するリラックス効果があると言われており、本発明の電気掃除機を作動した室内空間は快適になると考える。また、本発明のマイナス粒子発生装置は光電子を利用したものであるから、人体に対して有害なオゾンを原理的に発生しない。
【0010】
請求項2に記載した発明は、吸塵室とファンを内蔵しホース接続孔を設けた電気掃除機の本体部において、前記本体部内の吸塵室中にマイナス粒子発生装置を備え、前記マイナス粒子発生装置は、光電子発生材と前記光電子発生材の表面に紫外線を照射するための紫外線源とからなる構成とした。
【0011】
本発明の電気掃除機によれば、室内で発生する塵、ほこり等が蓄えられている吸塵室内に、光電子を利用するマイナス粒子発生装置を設けてなるので、マイナス粒子による除菌効果、及び紫外線源による除菌効果によって、吸塵室内でのカビ発生が抑制されることとなる。
【0012】
請求項3に記載の発明は、紫外線源を制御回路によって間欠運転することを特徴とする。
【0013】
紫外線を照射された光電子発生材から光電子が発生するが、光電子の発生に伴い光電子発生材は電気的に正に帯電するので、光電子を発生しにくい状態となる。そこで、本発明のように紫外線源の照射を制御回路によって間欠運転すれば、紫外線源がオフ時に光電子発生材は電気的に中和されるので、再び光電子発生材は光電子を発生しやすい状態に回復する。
【0014】
請求項4に記載の発明は、光電子発生材は電気的に接地されていることを特徴とする。
【0015】
光電子発生材を電気的に接地することによって、光電子発生後に光電子発生材が電気的に正に帯電することがなく、常に接地電位に保たれているので、経時的に安定してマイナス粒子を発生し続けることができる。
【0016】
請求項5に記載の発明は、光電子発生材を導電性基材上に設けてなることを特徴とする。
【0017】
光電子発生材としては、光電子の発生のし易さと防錆性等の耐久性に優れることの2点が要求される。貴金属は全般的にそれらの要求を満たす材料ではあるが、高価であるがために薄膜で使用せざるを得ない。その際、支持部材として導電性基材を用い、表面にメッキ、蒸着等の手法を用いて貴金属を設けることは、部材の剛性強化の観点からも有効である。
【0018】
請求項6に記載の発明は、光電子発生材は金、白金、銅、ステンレス、窒化チタンの中から選ばれた1種類以上の材料からなることを特徴とする。
【0019】
上述の様に、光電子発生材としては、光電子の発生のし易さと防錆性等の耐久性に優れることの2点が要求される。金、白金、銅等の貴金属はそれらの要求を満たす材料であり、また、ステンレス、窒化チタンは比較的安価な光電子発生材として優れている。
【0020】
【実施例】
以下、本発明の実施例について説明する。
【0021】
(実施例1)
図1は実施例1の電気掃除機の要部断面図である。図1において、1は電気掃除機の本体部であり、吸塵室2、ファン3、排気経路4、ホース接続孔5を備える。また、本体部1は外面に走行ローラー6、キャスターローラー7を備えるが、本発明とは機能上の関係は無い。排気経路4中にマイナス粒子発生装置8を設置した。
【0022】
図2に、マイナス粒子発生装置の要部側面図を示す。9は紫外線ランプ、10は円筒状の光電子発生材で、厚さ0.5mmの真鍮部材の表面に真空蒸着法によって厚さ約1ミクロンの金の薄層を蒸着した。ファン3を図示しない交流電源によって作動させる同時に、図示しないインバーター回路によって紫外線ランプ9を点灯した。その際、本体部1の排気経路4から本体外部へ排出される空気に含まれるマイナス粒子量を測定したところ、マイナス粒子濃度は約2万個/ccであった。また同時に、排出される空気に含まれるオゾン濃度を測定したところ、検出下限以下(1ppb以下)であった。
【0023】
この様に、本実施例記載の電気掃除機は、人体に有害なオゾンを発生することなく、マイナス粒子のみを含んだ空気を本体外へ排出することができるので、本電気掃除機を動作させる室内空気質は改善されることとなる。
【0024】
(実施例2)
以下、本発明の第2の実施例について図3を用いて説明する。マイナス粒子発生装置を吸塵室2に設置したこと以外は、第1の実施例とじであり、同一部分には同一符号を付与して詳細な説明を省略する。
【0025】
紫外線ランプ9は点灯せずにファン3のみを動作させた状態で、室内で本実施例の電気掃除機を約1時間運転させ、吸塵室2に若干の塵、ほこりを蓄えた。その後、ファン3の作動を止め、紫外線ランプ9を1時間点灯させた状態で放置した。その後、吸塵室2内の塵、ほこりから真菌を抽出して菌数測定したところ、塵、ほこり1gに対して生存する真菌数は50個以下である事が分かった。
【0026】
なお比較例として、上述の実験で紫外線ランプ9を点灯させずに放置した後に吸塵室の塵、ほこりから真菌を抽出して菌数を測定したところ、塵、ほこり1gに対して生存する菌数は約5千個であった。
【0027】
これらのことから、本実施例記載の電気掃除機では、吸塵室に蓄えられた塵、ほこりにカビ等の菌が増殖すると言った衛生上の問題を生じることが無いことが分かった。
【0028】
(実施例3)
以下本発明の第3の実施例について述べる。第1の実施例で述べた電気掃除機を用いて実験を行った。
【0029】
第1の実施例では紫外線ランプ9を連続点灯させて発生するマイナス粒子数を測定し、その結果2万個/ccであった。本実施例では紫外線ランプ9を1秒点灯、1秒消灯のサイクルで間欠運転させて発生するマイナス粒子濃度を測定したところ、4万個/ccであった。
【0030】
以上の様に本実施例の電気掃除機では、紫外線ランプを間欠運転することにより、更に多くのマイナス粒子を発生することが出来る。
【0031】
(実施例4)
以下、本発明の第4の実施例について述べる。第1の実施例の電気掃除機本体部1内に備えるマイナス粒子発生装置8の光電子発生材10を電気的に接地したこと以外は、第1の実施例と同一である。
【0032】
本実施例の電気掃除機から排出される空気中に含まれるマイナス粒子濃度を測定したところ、約5万個/ccであり、光電子発生材10を電気的に接地していない実施例1と比較して、飛躍的に発生するマイナス粒子数が増えることが分かった。また、排出空気中に含まれるオゾン濃度をを測定したところ、検出下限以下(1ppb以下)であることも分かった。
【0033】
この様に本実施例の電気掃除機は、人体に有害なオゾンを発生させることなく、人体に対するリラックス効果が有ると言われているマイナス粒子を含む空気を排出しながら掃除動作を行うことができる。
【0034】
(実施例5)
厚さ0.5mmの真鍮部材の表面に、それぞれ真空蒸着法によって厚さ約1ミクロンの金、白金、銅、ステンレス、窒化チタンの薄層を蒸着したものを作成した。なお、金を蒸着したものは実施例1で用いた部材と同一である。
【0035】
図1に示す電気掃除機本体部1中のマイナス粒子発生装置8に、白金、銅、ステンレス、窒化チタンを蒸着した真鍮部材をそれぞれ取り付けて発生するマイナス粒子濃度を測定したところ、いずれの場合も約2万個/ccであり、良好なマイナス粒子発生が確認できた。
【0036】
【発明の効果】
以上のように本発明の請求項1に記載の発明によれば、人体に有害なオゾンを排出することなく、人体に対してリラックス効果が有ると言われているマイナス粒子を含んだ空気を排出しながら掃除動作を行うことが出来、室内雰囲気を不快にすることがなくなるものである。
【0037】
また、本発明の請求項2に記載の発明によれば、吸塵室内に蓄えられる塵、ほこりからカビ等の菌が増殖すると言った衛生上の問題を生じることもなくなるものである。

As a result, it was found that the number of negative particles generated dramatically increased. Further, when the concentration of ozone contained in the exhaust air was measured, it was found that the concentration was below the lower limit of detection (1 ppb or less).
[0033]
As described above, the vacuum cleaner of the present embodiment can perform the cleaning operation while discharging air containing negative particles, which is said to have a relaxing effect on the human body, without generating ozone harmful to the human body. .
[0034]
(Example 5)
A thin layer of gold, platinum, copper, stainless steel, or titanium nitride having a thickness of about 1 micron was formed on the surface of a 0.5 mm-thick brass member by a vacuum evaporation method. Note that the members on which gold is deposited are the same as the members used in the first embodiment.
[0035]
When a negative particle generator 8 in the vacuum cleaner main unit 1 shown in FIG. 1 was attached with a brass member on which platinum, copper, stainless steel, and titanium nitride were deposited, the concentration of the negative particles generated was measured. It was about 20,000 particles / cc, and favorable generation of negative particles was confirmed.
