【発明の属する技術分野】
本発明は、空気清浄機能を有する電気掃除機に関するものである。
【0002】
【従来の技術】
従来の空気清浄機能付き電気掃除機は、電動送風機を駆動して吸込口から吸込気流を流入させ、集塵室、クリーンフィルター装置、空気清浄用送風機、排気口に至る排気風路を介して掃除機本体上面から排気させる。また、空気清浄機として使用する場合は、空気清浄用送風機を駆動して開口された空気清浄用吸気口から空気を吸い込み、クリーンフィルター装置、空気清浄用送風機、排気口に至る風路を介して掃除機本体上面から排気させる(例えば、特許文献1参照)。
【0003】
【特許文献1】
特開平4−352925号公報(第2−4頁、図1及び図3)
【0004】
【発明が解決しようとする課題】
このように従来の空気清浄機能付き電気掃除機は、電気掃除機用及び空気清浄機用の排気口が本体上面に配置されているため、掃除をしている際に、上向きの排気風によって空気中の浮遊塵埃を舞い上げてしまうといった問題があった。
また、掃除機能と空気清浄機能のどちらか一方の運転しかできないため、特に掃除中に床面より舞い上がった塵埃や浮遊塵埃を捕集することができなかった。
【0005】
さらに、掃除用と空気清浄用のクリーンフィルター装置及び排気口が同一であり、一般的に掃除用電動送風機は絨毯中の塵等を吸引するために強い吸引力を必要とするのに対し、空気清浄用送風機は空気中の塵埃を捕集するので吸引力が弱くても性能を満足させることができ、このため掃除用電動送風機と空気清浄用送風機との排気風速に差が生じ、排気フィルターの密度をどちらか一方の送風機に合わせたとしても、もう一方の送風機の性能を十分に生かすことができずに、電気掃除機と空気清浄機両方の吸塵性能を満足させることが困難であった。
【0006】
また、掃除機本体の電動送風機からの排気が、空気清浄用送風機を通過する構造となっているため、掃除用として運転した場合、または仮に電気掃除機と空気清浄機を同時に運転できたとしても、電気掃除機用電動送風機の排気によって空気清浄用送風機の規定回転数を超えて空気清浄用送風機のファンが回転することになり、空気清浄用送風機そのものの寿命を低下させてしまうことになる。
【0007】
本発明は、上記のような課題を解決するためになされたもので、空気中の浮遊塵埃を舞い上げずに、電動送風機と空気清浄用送風機それぞれの性能を十分に生かすことができ、また、空気清浄用送風機の寿命を低下させることがなく、電気掃除機として使用中に空気清浄機を使用する場合又は空気清浄機のみを使用する場合のいずれにおいても、吸塵効率の高い空気清浄を行うことができる空気清浄機能付き電気掃除機を提供することを目的とする。
【0008】
【課題を解決するための手段】
本発明に係る空気清浄機能付き電機掃除機は、掃除機本体を、第1の吸込口から集塵室、電動送風機、第1の排気フィルターを介して第1の排気口に至る排気風路を備えた掃除室と、その上部に位置し、第2の吸込口から空気清浄用送風機、第2の排気フィルターを介して第2の排気口に至る清浄風路を備えた清浄室とに区画し、掃除室の第1の吸込口を該掃除室の前部に配設するとともに、第1の排気口を掃除室の後部に配設、清浄室の第2の吸込口を第1の吸込口側から第1の排気口側に向かって上方向に傾斜させて清浄室の上部に配設するとともに、第2の排気口を清浄室の後部に配設したものである。
【0009】
【発明の実施の形態】
[実施の形態1]
図1は本発明の実施の形態1に係る空気清浄機能付き電気掃除機の全体構成図、図2は図1の空気清浄機能付き電気掃除機の本体の一部断面図である。図1において、空気清浄機能付き電気掃除機1は、掃除機本体2、掃除用吸込み具3、延長パイプ4、吸込み用ホース5によって構成され、ホース手元切替スイッチ6を備えている。なお、掃除機本体2には一対の走行用車輪7が取り付けられている。
【0010】
図2において、掃除機本体2は、仕切壁8によって上部の清浄室9と下部の掃除室10に区画されている。掃除室10の前部には吸込口(第1の吸込口)11、後部には排気口(第1の排気口)12が形成されるとともに、清浄室9の上部には空気清浄用吸込口(第2の吸込口)13、後部には空気清浄用排気口(第2の排気口)14が形成されている。
【0011】
掃除室10の吸込口11の下流には吸込口11に連通する集塵室15が設けられ、集塵室15の下流側には電動送風機16が配設され、電動送風機16の下流側に位置する排気口12には排気フィルター17(第1の排気フィルター)が取り付けられており、吸込口11から集塵室15、電動送風機16、排気フィルター17を通って排気口12に至る排気風路Aが形成されている。
【0012】
また、清浄室9の内部には空気清浄用吸込口13の近傍に、電動送風機16とは別にもう一つの空気清浄用送風機18が配設され、空気清浄用排気口14には空気清浄用フィルター19(第2の排気フィルター)が取り付けられている。そして、排気風路Aとは別の、空気清浄用吸込口13から空気清浄用送風機18、空気清浄用フィルター19を通って空気清浄用排気口14に至る清浄風路Bが形成されている。なお、空気清浄用フィルター19は空気清浄用排気口14側に取り付けたが、空気清浄用吸込口13側に取り付けても良い。
【0013】
なお、図1に示したホース手元切替スイッチ6は、電動送風機16の動作がONでかつ空気清浄用送風機18の動作がOFFであるモードと、電動送風機16と空気清浄用送風機18の動作が共にONであるモードと、電動送風機16の動作がOFFでかつ空気清浄用送風機18の動作がONであるモードと、電動送風機16と空気清浄用送風機18の動作が共にOFFであるモードとの4通りのモードに切り替えらることができるようになっている。
【0014】
上記のように構成した実施の形態1の作用を説明する。まず、電動送風機16と空気清浄用送風機18を共にONモードにすると、通常の掃除をしながら、空気中の浮遊塵埃を空気清浄用吸込口13より空気清浄用送風機18によって吸気し、空気清浄用フィルター19でろ過して空気清浄用排気口14より排気して空気清浄を行う。また、電動送風機16の動作をOFFモードにし、かつ空気清浄用送風機18の動作をONモードにすると、掃除の際に舞い上がった埃を掃除終了後の後片づけをしている最中に捕集することができる。あるいは、掃除機本体2を立てて収納状態にして空気清浄のみの運転をすることもできる。
【0015】
このように空気清浄機能を使用する場合に、空気清浄用吸気口13が掃除機本体2の上面に位置しており、排気口12及び空気清浄用排気口14は掃除機本体2の上面を除く部分、例えば掃除機本体2の後部に位置しているため、排気によって空気中の浮遊塵埃を舞い上げることなく、効率よく浮遊塵埃を捕集することができる。
【0016】
また、排気口12における排気フィルター17の密度は電動送風機16の排気風速に、また空気清浄用排気口14における空気清浄用フィルター19の密度は空気清浄用送風機18の排気風速にそれぞれ合わせて設定しているため、電動送風機16及び空気清浄用送風機18のそれぞれの寿命を損ねることなく、それぞれの性能を十分に発揮させることができる。
【0017】
[実施の形態2]
図3は本発明の実施の形態2に係る空気清浄機能付き電気掃除機1の掃除機本体2の一部断面図、図4は図3のX−X矢視断面図である。なお、図2と同一部分については同じ符号を付し、説明を省略する。図3において、掃除機本体2は、仕切壁8によって上部の清浄室9と下部の掃除室10に区画され、さらに仕切壁8には、空気清浄用送風機18からの排気を排気風路Aに案内する排気ガイド体20が形成され、この排気ガイド体20の終端開口部を排気フィルター17の近傍に位置させている。
【0018】
また、掃除機本体2の掃除室10の前部には吸込口11、後部には排気口12が形成され、清浄室9の上部には空気清浄用吸込口13が形成されている。さらに、電動送風機16の下流側に位置する排気口12には排気フィルター17が取り付けられており、吸込口11から集塵室15、電動送風機16、排気フィルター17を通って排気口12に至る排気風路Aが形成されている。また、清浄室9の内部には空気清浄用吸込口13の近傍に空気清浄用送風機18が配設され、空気清浄用吸い込み口13から空気清浄用送風機18、排気ガイド体20に至り、排気風路Aと合流する清浄風路Cが形成されている。このように、本実施の形態においては、排気風路Aと清浄風路Cを1つの排気口12に導くようにしている。
【0019】
上記の構成において、排気口12における排気フィルター17の密度は、電動送風機16の排気風速に合わせて設定されている。電気掃除機として使用中に空気清浄機能を使用する場合、電動送風機16の排気風速よりも空気清浄用送風機18の排気風速は低いが、空気清浄用送風機18の清浄風路Cを電動送風機16の排気風路Aに合流させることにより、電動送風機16の排気が空気清浄用送風機18からの排気を引き出して、空気清浄用送風機18側の排気の風速を上げることができる。このため、排気フィルターを共通化することができ、フィルター密度を電動送風機16の排気風速に合わせられるため、安価でかつ捕集効率の高い空気清浄が可能となる。更に、実施の形態1に比べて掃除機本体2の高さを低くすることができる。
【0020】
[実施の形態3]
図5は本発明の実施の形態3に係る空気清浄機能付き電気掃除機1の掃除機本体2の一部断面図である。なお、図2と同一部分には同じ符号を付し、説明を省略する。図において、掃除機本体2の上面部は、その面21を掃除機本体2の吸込口11側に向けて下方に傾斜するようにして形成されている。すなわち、掃除機本体2の上面21に設けた清浄室9の空気清浄用吸込口13が、掃除機本体2の吸込口11側から排気口12側にかけて上向きになるように傾斜して形成されている。
こうして、電気掃除機を使用中に空気清浄機能を使用する際、掃除機本体2の進行方向イに対して空気清浄用吸込口13の面が空気中を斜めに横切ることとなり、空気中の塵埃の捕集性能がより向上する。
【0021】
掃除が終了した後は、図6に示すように、掃除機体2を立てた状態、すなわち収納状態にして空気清浄機能を使用すると、空気清浄用吸込口13は斜めに上方に傾斜した状態になり、浮遊塵埃が落下してくる方向に対して空気清浄用吸込口13が斜めに当たるようになるため、空気中に浮遊しあるいは落下してくる塵埃を効率よく空気清浄用吸込口13に導くことができ、空気中の塵埃の捕集性能がより向上する。
【0022】
[実施の形態4]
図7は本発明の実施の形態4に係る空気清浄機能付き電気掃除機1の掃除機本体2の一部断面図である。なお、図5と同一部分には同じ符号を付し、説明を省略する。本実施の形態においては、掃除機本体2の清浄室9内の空気清浄用フィルター19の内側近傍にマイナスイオン発生体22を取付け、このマイナスイオン発生体22からのマイナスイオン23を、空気清浄用送風機18の排気により、掃除機本体2外の空気中に放出させる。こうして、プラスに帯電した空気中の微細な埃24がマイナスイオン23によって中和して結合され、その結合によって大きくなった埃25は自重によって落下しやすくなることで、空気清浄の捕集効率を更に向上させることができる。
【0023】
上記の説明では、マイナスイオン23を発生させる手段としては、マイナスイオン発生体22を空気清浄用フィルター19の内側近傍に取り付けた場合を示したが、排気フィルター17の内側に取り付けてもよく、あるいは掃除機本体2内部の風路内の何れの位置に配置するものであってもよい。また、排気フィルター17または空気清浄用フィルター19内に例えばトルマリン鉱石のような原料を含浸させ、排気の風圧または電動送風機16の排気熱によってここからマイナスイオン23を発生させるようにしてもよい。
【0024】
【発明の効果】
以上の説明から明らかなように、本発明に係る空気清浄機能付き電気掃除機によれば、電気掃除機として使用中に空気清浄機能を使用する場合、または空気清浄機としてのみ使用する場合のいずれにおいても、空気中の浮遊塵埃を舞い上げず、空気中に浮遊している塵埃または自重により落下してくる塵埃を上から効率よく空気清浄用吸込口へ導くことができ、捕集効率の高い空気清浄を行うことができる。また、空気清浄用送風機の寿命を損ねることなく、電動送風機と空気清浄機用送風機それぞれの性能を十分に発揮させることができ、その結果、電気掃除機及び空気清浄のいずれにおいても高い吸塵性能が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a vacuum cleaner having an air cleaning function.
[0002]
[Prior art]
A conventional vacuum cleaner with an air purifying function drives an electric blower to cause a suction airflow to flow from the suction port, and the vacuum cleaner passes through a dust collection chamber, a clean filter device, an air cleaning blower, and an exhaust air passage leading to an exhaust port. Exhaust from the top of the body. When used as an air purifier, the air purifier is driven to suck in air from the air purifier intake opening, and is cleaned through the air path leading to the clean filter device, the air purifier blower, and the exhaust vent. The air is exhausted from the upper surface of the machine body (for example, see Patent Document 1).
[0003]
[Patent Document 1]
JP-A-4-352925 (page 2-4, FIGS. 1 and 3)
[0004]
[Problems to be solved by the invention]
As described above, the conventional vacuum cleaner with an air purifying function has the exhaust ports for the vacuum cleaner and the air purifier disposed on the upper surface of the main body. There was a problem of floating the floating dust inside.
In addition, since only one of the cleaning function and the air cleaning function can be operated, it was not possible to collect dust and floating dust rising from the floor surface during cleaning.
[0005]
In addition, the cleaning filter device and the exhaust port for cleaning are the same, and the electric blower for cleaning generally requires a strong suction force to suck dust and the like in the carpet, whereas the air cleaner Because the air blower collects dust in the air, it can satisfy the performance even if the suction force is weak.Therefore, there is a difference in the exhaust air speed between the cleaning electric blower and the air cleaning blower, and the density of the exhaust filter Even if it is matched with one of the blowers, the performance of the other blower cannot be fully utilized, and it is difficult to satisfy the dust absorption performance of both the vacuum cleaner and the air cleaner.
[0006]
In addition, because the exhaust from the electric blower of the main body of the vacuum cleaner has a structure that passes through the air cleaning fan, even if it is operated for cleaning, or even if the electric vacuum cleaner and the air cleaner can be operated simultaneously The exhaust of the electric blower for an electric vacuum cleaner causes the fan of the air cleaning blower to rotate exceeding the specified rotational speed of the air purifying blower, thereby reducing the life of the air purifying blower itself.
[0007]
The present invention has been made to solve the above-described problems, and can sufficiently utilize the performance of each of the electric blower and the air cleaning blower without raising airborne dust in the air. Perform air cleaning with high dust absorption efficiency when using an air purifier while using it as a vacuum cleaner, or when using only an air purifier, without reducing the life of the air purifier. An object of the present invention is to provide an electric vacuum cleaner with an air purifying function.
[0008]
[Means for Solving the Problems]
The electric vacuum cleaner with an air purifying function according to the present invention has an exhaust air passage extending from the first suction port to the first exhaust port via the dust collection chamber, the electric blower, and the first exhaust filter. A clean room with a clean air passage located at the upper part of the cleaning chamber and provided with a clean air passage extending from the second suction port to the second exhaust port through the air exhaust fan and the second exhaust filter. The first suction port of the cleaning chamber is disposed at the front portion of the cleaning chamber, the first exhaust port is disposed at the rear portion of the cleaning chamber, and the second suction port of the cleaning chamber is disposed as the first suction port . Inclined upward from the mouth side toward the first exhaust port side and disposed at the upper portion of the clean chamber, and the second exhaust port is disposed at the rear portion of the clean chamber.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
[Embodiment 1]
1 is an overall configuration diagram of a vacuum cleaner with an air cleaning function according to Embodiment 1 of the present invention, and FIG. 2 is a partial cross-sectional view of a main body of the vacuum cleaner with an air cleaning function of FIG. In FIG. 1, the vacuum cleaner 1 with an air cleaning function includes a vacuum cleaner body 2, a cleaning suction tool 3, an extension pipe 4, and a suction hose 5, and includes a hose hand changeover switch 6. A pair of traveling wheels 7 are attached to the cleaner body 2.
[0010]
In FIG. 2, the cleaner body 2 is divided into an upper cleaning chamber 9 and a lower cleaning chamber 10 by a partition wall 8. A suction port (first suction port) 11 is formed in the front portion of the cleaning chamber 10, an exhaust port (first exhaust port) 12 is formed in the rear portion, and an air cleaning suction port is formed above the clean chamber 9. (Second suction port) 13 and an air cleaning exhaust port (second exhaust port) 14 are formed at the rear.
[0011]
A dust collection chamber 15 that communicates with the suction port 11 is provided downstream of the suction port 11 of the cleaning chamber 10, and an electric blower 16 is disposed downstream of the dust collection chamber 15, and is positioned downstream of the electric blower 16. An exhaust filter 17 (first exhaust filter) is attached to the exhaust port 12, and an exhaust air path A extending from the suction port 11 through the dust collection chamber 15, the electric blower 16, and the exhaust filter 17 to the exhaust port 12. Is formed.
[0012]
In addition to the electric blower 16, another air cleaning fan 18 is disposed in the clean chamber 9 near the air cleaning inlet 13, and the air cleaning exhaust port 14 has an air cleaning filter. 19 (second exhaust filter) is attached. A clean air passage B is formed separately from the exhaust air passage A and extends from the air cleaning suction port 13 through the air cleaning fan 18 and the air cleaning filter 19 to the air cleaning exhaust port 14. Although the air cleaning filter 19 is attached to the air cleaning exhaust port 14 side, it may be attached to the air cleaning suction port 13 side.
[0013]
In addition, the hose hand changeover switch 6 shown in FIG. 1 has both the mode in which the operation of the electric blower 16 is ON and the operation of the air cleaning fan 18 is OFF, and the operation of the electric blower 16 and the air cleaning fan 18. There are four modes: an ON mode, a mode in which the operation of the electric blower 16 is OFF and an operation of the air cleaning fan 18 is ON, and a mode in which the operations of the electric blower 16 and the air cleaning fan 18 are both OFF. The mode can be switched to.
[0014]
The operation of the first embodiment configured as described above will be described. First, when both the electric blower 16 and the air cleaning fan 18 are set to the ON mode, air dust is sucked in from the air cleaning suction port 13 by the air cleaning blower 18 while performing normal cleaning. The air is purified by filtering through a filter 19 and exhausting from the air cleaning exhaust port 14. Further, when the operation of the electric blower 16 is set to the OFF mode and the operation of the air cleaning blower 18 is set to the ON mode, dust that has risen during cleaning is collected during cleaning after cleaning. be able to. Alternatively, the cleaner main body 2 can be stood up and housed to operate only for air cleaning.
[0015]
When the air purifying function is used in this way, the air purifying intake port 13 is located on the upper surface of the cleaner body 2, and the exhaust port 12 and the air purifying exhaust port 14 exclude the upper surface of the cleaner body 2. Since it is located at the rear part of the vacuum cleaner body 2, for example, the floating dust can be efficiently collected without raising the floating dust in the air by exhaust.
[0016]
The density of the exhaust filter 17 at the exhaust port 12 is set according to the exhaust air speed of the electric blower 16, and the density of the air cleaning filter 19 at the air cleaning exhaust port 14 is set according to the exhaust air speed of the air cleaning fan 18. Therefore, each performance can be fully exhibited without impairing the lifetime of each of the electric blower 16 and the air cleaning blower 18.
[0017]
[Embodiment 2]
3 is a partial cross-sectional view of the vacuum cleaner body 2 of the vacuum cleaner 1 with an air cleaning function according to Embodiment 2 of the present invention, and FIG. 4 is a cross-sectional view taken along the line XX of FIG. The same parts as those in FIG. 2 are denoted by the same reference numerals, and description thereof is omitted. In FIG. 3, the cleaner body 2 is divided into an upper cleaning chamber 9 and a lower cleaning chamber 10 by a partition wall 8, and exhaust gas from an air cleaning blower 18 is exhausted to an exhaust air passage A in the partition wall 8. An exhaust guide body 20 to be guided is formed, and a terminal opening of the exhaust guide body 20 is positioned in the vicinity of the exhaust filter 17.
[0018]
In addition, a suction port 11 is formed in the front portion of the cleaning chamber 10 of the cleaner body 2, an exhaust port 12 is formed in the rear portion, and an air cleaning suction port 13 is formed in the upper portion of the clean chamber 9. Further, an exhaust filter 17 is attached to the exhaust port 12 located on the downstream side of the electric blower 16, and exhaust from the suction port 11 to the exhaust port 12 through the dust collection chamber 15, the electric blower 16, and the exhaust filter 17. An air path A is formed. Further, an air cleaning fan 18 is disposed in the vicinity of the air cleaning inlet 13 inside the cleaning chamber 9 and reaches the air cleaning fan 18 and the exhaust guide body 20 from the air cleaning inlet 13 to the exhaust air. A clean air path C that merges with the path A is formed. Thus, in the present embodiment, the exhaust air path A and the clean air path C are guided to one exhaust port 12.
[0019]
In the above configuration, the density of the exhaust filter 17 at the exhaust port 12 is set according to the exhaust air speed of the electric blower 16. When the air cleaning function is used during use as a vacuum cleaner, the exhaust air speed of the air cleaning fan 18 is lower than the exhaust air speed of the electric blower 16, but the clean air path C of the air cleaning fan 18 is connected to the electric fan 16. By merging with the exhaust air path A, the exhaust of the electric blower 16 can draw the exhaust from the air cleaning fan 18 and increase the wind speed of the exhaust on the air cleaning fan 18 side. For this reason, the exhaust filter can be used in common, and the filter density can be matched with the exhaust air speed of the electric blower 16, so that air purification that is inexpensive and has high collection efficiency is possible. Furthermore, the height of the cleaner body 2 can be reduced as compared with the first embodiment.
[0020]
[Embodiment 3]
FIG. 5 is a partial cross-sectional view of the cleaner body 2 of the electric vacuum cleaner 1 with an air cleaning function according to Embodiment 3 of the present invention. In addition, the same code | symbol is attached | subjected to the same part as FIG. 2, and description is abbreviate | omitted. In the figure, the upper surface portion of the cleaner body 2 is formed such that its surface 21 is inclined downward toward the suction port 11 side of the cleaner body 2. That is, the air cleaning suction port 13 of the cleaning chamber 9 provided on the upper surface 21 of the cleaner body 2 is formed so as to be inclined upward from the suction port 11 side to the exhaust port 12 side of the cleaner body 2. Yes.
Thus, when using the air cleaning function while using the electric vacuum cleaner, the surface of the air cleaning inlet 13 crosses the air obliquely with respect to the traveling direction (a) of the vacuum cleaner body 2, and dust in the air This improves the collection performance.
[0021]
After the cleaning is completed, as shown in FIG. 6, when the cleaner 2 is in the upright state, that is, in the stowed state and the air cleaning function is used, the air cleaning inlet 13 is inclined obliquely upward. Since the air cleaning inlet 13 strikes obliquely with respect to the direction in which the floating dust falls, the dust floating or falling in the air can be efficiently guided to the air cleaning inlet 13. This improves the dust collection performance in the air.
[0022]
[Embodiment 4]
FIG. 7 is a partial cross-sectional view of the cleaner body 2 of the vacuum cleaner 1 with an air cleaning function according to Embodiment 4 of the present invention. In addition, the same code | symbol is attached | subjected to the same part as FIG. 5, and description is abbreviate | omitted. In the present embodiment, a negative ion generator 22 is attached in the vicinity of the inside of the air cleaning filter 19 in the cleaning chamber 9 of the cleaner body 2, and the negative ions 23 from the negative ion generator 22 are used for air cleaning. The exhaust air from the blower 18 is discharged into the air outside the cleaner body 2. In this way, the positively charged fine dust 24 in the air is neutralized and combined by the negative ions 23, and the dust 25 that has become larger due to the combination is easily dropped by its own weight, thereby improving the collection efficiency of the air cleaning. Further improvement can be achieved.
