【従来の技術】
従来の水拭き掃除を可能にした電気掃除機は、床用吸込具に取り付けたスポンジ体に給水するために、スポンジ体を水に浸し、その後電気掃除を運転し、スポンジ体の水分を吸水する必要がある。そのため、電気掃除機本体は水を吸い込むことが可能な十分な防水構成を有する必要があり、複雑な本体構成が必要になる。又、水拭き掃除と、乾いたゴミの吸引掃除を床用吸込具の付け替え無しに行うことは難しく、水拭き掃除用の床用吸込具と一般ゴミ用床用吸込具を兼ねることは難しく、電動の回転ブラシを内包することも難しい（例えば、特許文献１参照）。

【００１５】
【実施例】
（実施例１）
図１に、本発明の第一の実施例における電気掃除機を示す。１１は電動送風機１１ａを内蔵した掃除機本体を示し、集塵部１４に設けた吸引部２５に接続されたホース１６、延長管１７を介して吸口１２が接続されている。すなわち電動送風機の吸引力により床面１３の塵埃などが吸口１２から吸引され、集塵部１４で塵埃が分離蓄積される。図２は横長形状の吸口１２の断面図を示し、２１は周囲にゴム材からなる柔軟なリップ２０を配置した床面を掃くあるいは拭くための回転ワイパであり、電動機（図示せず）により駆動される。２２はミスト発生部を示し、水を貯えるタンク２２ａと、開閉弁２２ｂを有した給水口２２ｃと微少な滴下口２２ｄから構成されている。これらのミスト発生部２２は上下方向に可動でき、滴下口２２ｄを十分に床面１３に接近させることができる。２３は水分の分離タンクである。２４は吸口接続パイプであり延長管１７に着脱自在に接続できる。２６は分離タンク２３に水分が混じった気流が流入する吸水口を示し、その上流側は狭く絞った前通路２６ａが構成されている。２７は吸気口扉を示し、開閉可能で開けば直接大きな風量が吸引され、閉じれば流速が早められた気流が吸水口２６から流入する。
【００１６】
次に動作について説明する。吸口１２に吸引される矢印３０ａに示す気流により滴下口２２ｄよ表出した水滴は細かい粒子に霧化され床面１３に水分を供給し、床面１３に付着した飲料物などの跡の汚れを軟化させる。軟化し水分に融けた汚れは回転ワイパに２１により機械的に剥離され気流３０ａと共に吸水口２６から吸引される。吸水口２６から分離タンク２３に流入した流れ３０ｂは、急速に減速されるため水分３３は下方向に向かい分離タンク２３内に蓄積する。水分が分離された後の気流３０ｃ吸口接続パイプ２４を通過し延長管１７へ流入する。すなわち分離タンク２３で汚れを含んだ水分が分離される。
【００１７】
水分を効果的に分離するためには、分離タンク２３で気流が急減速する必要がある。又、水分が空気と共に吸引されるためには流速が大きいことが必要である。本実施例では床面１３から剥離された水に融けた汚れは回転ワイパ２１のリップ２０により機械的な力により跳ね上げられ流速を大きくするために面積を絞った前通路２６ａを経て吸水口２６から気流と共に吸い込まれる。分離タンク２３での気流の流れる断面積は吸水口２６に比べ非常に大きいため流速は急減速され、水分は気流と共に流れる事ができなくなり重力により下方向に落下し水分が分離され、延長管１７に水分はほとんど流入しない。
【００１８】
一般に掃除機に使用する電動送風機１１ａは遠心型で大きな圧力が発生できる。そのため吸水口２６、前通路２６ａなどで通路を絞ると、風量は小さくなるが前通路２６ａ、吸水口２６では大きな風速が得られる。すなわち低風量ではあるが、水分を含んだ高速な気流が分離タンク２３内に流入し、急激に減速される。又、風量自身が小さくなっているため断面積の比較的大きい延長管１７に流入する流速は小さく水分が気流に運ばれ掃除機本体１１に流入することは無い。又、流路を絞り圧力が高くなり過ぎ、吸口１２が床面１３に吸着し操作性が悪くなるような場合は、電動送風機１１への入力を下げ、更に低風量で運転しても、前通路２６ａの断面積を更に小さくすれば流速は大きくすることができ、水分を吸引することが可能である。
【００１９】
３２は水分を含んだ気流が後方に流れるの防ぎ、上方に跳ね上げやすくするための床面リップを示す。ミストの量は開閉弁２２ｂの開閉あるいは開口度を変えることにより滴下量を可変することにより制御できる。この吸口１２を乾燥した一般の塵埃の掃除をするために使用するには、図２（ｂ）のように開閉弁２２ｂを閉じ、滴下口２２ｄからの水分の表出を止め、吸気口扉２７を開け、ミスト発生部２２を上方に移動させ、滴下口２２ｄと床面１３の距離を大きくし、風が流れやすくする。このようにすれば矢印３０ｄで示すような大きな風量で一般の乾燥した塵埃の掃除が行える。
【００２０】
水拭き掃除と一般の掃除の切り替えは一連の掃除動作中でも可能である。分離タンク２３に溜まった水分を捨てるには、吸口１２を延長管１７から外し吸口接続パイプ２４から捨てれば良い。又別に排水口を設けることも、着脱可能な構成にすることも可能である。又、掃除機本体の排気流を利用して分離タンク２３内に気流を送り、水分の排出と乾燥を行うことも考えられる。
【００２１】
（実施例２）
図３（ａ）は本発明の第２の実施例を示す電気掃除機の吸口１２を示す。本実施例は、吸水口４６を回転ワイパ４１の周囲に設けた場合であり、床面１３から吸い込まれた水分は回転ワイパ４１内の通路４１ａを通り、その端面４１ｂに設けた連通管４２を通り分離タンク２３に開口した連通管出口４２ａから分離タンク２３へ矢印３９で示す気流と共に吸引される。このような構成では、吸水口４６を床面１３に近づけることができより迅速に床面１３の水に溶けた汚れを吸い取ることが可能になる。図４は回転ワイパ４１を正面から見た端面４１ｂ部分の拡大断面図である。矢印３９ａは水分３８が分離した後、掃除機本体へ吸引される気流の流れを示す。
【００２２】
図３（ｂ）は回転ワイパ４１の周囲をスポンジなどの吸水体４３で構成した例であり、水分に融けた床面１３の汚れはいったん吸水体４３に吸い取られ、その後回転ワイパ４１の外周に設けた吸水口４６から吸引される。この構成では床面１３に直接吸水体４３が接触するため、効果的な吸水、水拭き掃除ができる。図５は吸口１２を底面からみた一部断面図を示している。矢印３９は水分を含んだ気流の流れを示し、３８は分離された水分を示す。
【００２３】
図６に示すように、分離タンク２３に開閉蓋Ａ６５を設けた吸気口６４を設置し、連通管４２の出口４２ａにも開閉蓋Ｂ６６を設け、水拭き掃除時には開閉蓋Ａ６５を閉じ、開閉蓋Ｂを開け、乾燥ゴミを対象とする一般掃除時には開閉蓋Ａ６５を開ければ、それぞれの掃除に対し適切な流量が選られ掃除性能が向上する。すなわち水拭き掃除時には高圧低風量の流れ、一般掃除時には低圧大風量の流れを得やすくなる。矢印６７ａは水拭き掃除時の気流の流れを、矢印６７ｂは一般掃除時の気流の流れを示す。
【００２４】
図７は、回転ワイパ４１の外周に吸水体４３を巻いているが、吸水口４６は外部に設けた例であり、床面１３に吸水体４３が接触した時に床面から吸水し、吸水口４６に近づいた時に吸水体４３の水分が分離タンク２３へ吸引される構成である。吸水体４３の表面に圧接した突起前４４は吸水体４３の水分を絞る役目をし、吸水体４３の表面にわずかに当接した突起後４４ｂは水分の床面１３への逆流を防止している。４５は水滴を、矢印３０は気流の流れを、矢印４０は回転ワイパ４１の回転方向を示している。
【００２５】
（実施例３）
図８、図９を用いて本発明の第３の実施例について説明する。図８（ｂ）は回転ワイパ５１部分の拡大図、図９は吸口１２を正面からみた一部断面図を示す。５２は水タンクであり連通管５０によって回転ワイパ５１の内部に設置され、下側に多数の滴下口５３を有する給水管５４に接続されている。給水管５４は固定されており回転はせず、回転ワイパ５１は回転できる。５１ａは床面を拭くため回転ワイパ５１の外周に設置したゴム質のリップであり、５５はやはり回転ワイパ５１の外周に設けたミストの排出口５５を示す。回転ワイパ５１が回転しているとき内部に滴下口５３より矢印５３ｂで示すように水滴５３ａが落ちると回転ワイパの内壁５１ｂで弾かれ霧散すると同時に排出口５５より遠心力で外部に微少な水滴すなわちミストとして排出される。ミストは前記実施例で述べたように、床面１３の汚れを溶かし、溶けた汚れは回転ワイパ５１で床面１３から簡単に剥離され、吸水口５６より吸引される。矢印６０は回転ワイパ５１の外周より放出されたミストの流れを、矢印６０ａは水分に溶けた汚れを含む気流の流れを、矢印６０ｂは水分３８が分離した後の気流の流れを示す。
【００２６】
図１０（ａ）はスポンジ等の多孔質体５７が多数の排出口５５を有した回転ワイパ５１の外周に巻かれた例であり、ミストはこの多孔質体５７から遠心力により外部に排出され、汚れを溶かすと同時に多孔質体５７が汚れを剥離し、気流と共に吸水口５６より吸入される。この方法は、濡れ雑巾と同様の働きをし、効果的に床面１３の汚れを除去できる。
【００２７】
又、図１０（ｂ）の様に回転ワイパ５１の中に給水タンク５２を設置しても良い。この場合は排出口５５ａは滴下口を兼ねる構成となり、吸口１２全体の構成が簡素化される。矢印６０ａは水分に溶けた汚れを含む気流の流れを、矢印６０ｂは水分３８が分離した後の気流の流れを示す。
【００２８】
図１０で示すように、分離タンク２３に開閉蓋Ａ６５を設けた吸気口６４を設置し、連通管４２の出口４２ａにも開閉蓋Ｂ６６を設け、水拭き掃除時には開閉蓋Ａを閉じ、開閉蓋Ｂを開け、一般掃除時には開閉蓋Ｂを開ければ、それぞれの掃除に対し適切な流量が選られ掃除性能が向上する。
【００２９】
【発明の効果】
以上のように本発明によれば、吸口内に設けることが可能な少量タイプのミスト発生部を用いて、従来の乾燥ごみの掃除はもちろんのこと、簡単な床面の水拭き掃除も、同一の吸口で行えるものである。

【Example】
(Example 1)
FIG. 1 shows a vacuum cleaner according to a first embodiment of the present invention. Reference numeral 11 denotes a vacuum cleaner main body incorporating the electric blower 11 a, and the suction port 12 is connected via a hose 16 and an extension pipe 17 connected to a suction part 25 provided in the dust collecting part 14. That is, dust or the like on the floor surface 13 is sucked from the suction port 12 by the suction force of the electric blower, and the dust is separated and accumulated in the dust collecting portion 14. FIG. 2 is a cross-sectional view of the horizontally-shaped suction mouth 12, and 21 is a rotary wiper for sweeping or wiping the floor surface on which a flexible lip 20 made of a rubber material is disposed, and is driven by an electric motor (not shown). Is done. Reference numeral 22 denotes a mist generating portion, which is composed of a tank 22a for storing water, a water supply port 22c having an on-off valve 22b, and a minute dripping port 22d. These mist generating parts 22 can move in the vertical direction, and the dripping port 22d can be made sufficiently close to the floor surface 13. Reference numeral 23 denotes a moisture separation tank. An inlet connection pipe 24 is detachably connected to the extension pipe 17. Reference numeral 26 denotes a water intake port through which an airflow mixed with moisture flows into the separation tank 23, and a narrow front passage 26a is formed on the upstream side thereof. Reference numeral 27 denotes an air inlet door, which can be opened and closed. When it is opened, a large air volume is directly sucked.
[0016]
Next, the operation will be described. The water droplets exposed from the dripping port 22d by the air flow indicated by the arrow 30a sucked into the sucking port 12 are atomized into fine particles to supply moisture to the floor surface 13, and traces such as beverages adhering to the floor surface 13 are removed. Soften. The dirt that has been softened and melted into the water is mechanically peeled off by the rotary wiper 21 and sucked from the water inlet 26 together with the air flow 30a. Since the flow 30b flowing into the separation tank 23 from the water inlet 26 is rapidly decelerated, the moisture 33 accumulates in the separation tank 23 in the downward direction. After the moisture is separated, it passes through the airflow 30c inlet connection pipe 24 and flows into the extension pipe 17. That is, the water containing dirt is separated in the separation tank 23.
[0017]
In order to effectively separate moisture, the airflow needs to be rapidly decelerated in the separation tank 23. In addition, a high flow rate is necessary for moisture to be sucked together with air. In this embodiment, the dirt melted in the water peeled off from the floor surface 13 is splashed up by the mechanical force of the lip 20 of the rotary wiper 21 and is passed through the front passage 26a with a reduced area in order to increase the flow velocity. From the air. Since the cross-sectional area in which the airflow flows in the separation tank 23 is much larger than that of the water inlet 26, the flow velocity is rapidly decelerated, the water cannot flow with the airflow, falls downward due to gravity, and the water is separated. Almost no moisture flows into it.
[0018]
Generally, the electric blower 11a used for the vacuum cleaner is a centrifugal type and can generate a large pressure. Therefore, when the passage is narrowed by the water inlet 26, the front passage 26a, etc., the air volume is reduced, but a large wind speed is obtained at the front passage 26a, the water inlet 26. That is, although the air volume is low, a high-speed air stream containing moisture flows into the separation tank 23 and is rapidly decelerated. Further, since the air volume itself is small, the flow velocity flowing into the extension pipe 17 having a relatively large cross-sectional area is small, so that moisture is carried by the air current and does not flow into the cleaner body 11. In addition, when the throttle pressure in the flow path becomes too high and the suction port 12 is adsorbed on the floor surface 13 and the operability becomes poor, the input to the electric blower 11 is lowered, and even if the operation is performed with a low air flow, If the cross-sectional area of the passage 26a is further reduced, the flow velocity can be increased and moisture can be sucked.
[0019]
Reference numeral 32 denotes a floor lip for preventing an air current containing moisture from flowing backward and facilitating upward splashing. The amount of mist can be controlled by varying the amount of dripping by changing the opening / closing or opening degree of the on-off valve 22b. In order to use the suction port 12 for cleaning dry dry dust, as shown in FIG. 2B, the on-off valve 22b is closed to prevent the moisture from appearing from the dripping port 22d. And the mist generating part 22 is moved upward to increase the distance between the dripping port 22d and the floor surface 13 so that the air can flow easily. In this way, general dry dust can be cleaned with a large air flow as indicated by the arrow 30d.
[0020]
Switching between water cleaning and general cleaning is possible even during a series of cleaning operations. In order to discard the water accumulated in the separation tank 23, the suction port 12 may be removed from the extension pipe 17 and discarded from the suction connection pipe 24. It is also possible to provide a separate drainage port or to be detachable. It is also conceivable to use an exhaust flow of the cleaner body to send an air flow into the separation tank 23 to discharge and dry the moisture.
[0021]
(Example 2)
Fig.3 (a) shows the inlet 12 of the vacuum cleaner which shows the 2nd Example of this invention. In this embodiment, the water suction port 46 is provided around the rotary wiper 41, and the moisture sucked from the floor surface 13 passes through the passage 41a in the rotary wiper 41 and passes through the communication pipe 42 provided on the end surface 41b. The air is drawn into the separation tank 23 from the communication pipe outlet 42a opened in the street separation tank 23 together with the air flow indicated by the arrow 39. In such a configuration, the water suction port 46 can be brought close to the floor surface 13, and dirt dissolved in the water on the floor surface 13 can be sucked up more quickly. FIG. 4 is an enlarged cross-sectional view of the end face 41b portion when the rotary wiper 41 is viewed from the front. An arrow 39a indicates the flow of air flow sucked into the cleaner body after the moisture 38 is separated.
[0022]
FIG. 3B is an example in which the periphery of the rotating wiper 41 is configured by a water absorbing body 43 such as a sponge. The dirt on the floor surface 13 melted in moisture is once absorbed by the water absorbing body 43 and then on the outer periphery of the rotating wiper 41. Suction is provided from the provided water inlet 46. In this structure, since the water absorption body 43 contacts the floor surface 13 directly, effective water absorption and water wiping cleaning can be performed. FIG. 5 shows a partial cross-sectional view of the suction port 12 as viewed from the bottom. An arrow 39 indicates the flow of the air stream containing moisture, and 38 indicates the separated moisture.
[0023]
As shown in FIG. 6, an intake port 64 provided with an opening / closing lid A65 is installed in the separation tank 23, an opening / closing lid B66 is also provided at the outlet 42a of the communication pipe 42, and the opening / closing lid A65 is closed when cleaning with water. If the opening / closing lid A65 is opened during general cleaning for dry dust, an appropriate flow rate is selected for each cleaning and the cleaning performance is improved. That is, it becomes easy to obtain a flow of high pressure and low airflow during water wiping cleaning and a flow of low pressure and large airflow during general cleaning. An arrow 67a indicates a flow of airflow during water cleaning, and an arrow 67b indicates a flow of airflow during general cleaning.
[0024]
FIG. 7 shows an example in which a water absorber 43 is wound around the outer periphery of the rotary wiper 41, but the water inlet 46 is provided outside, and when the water absorber 43 comes into contact with the floor surface 13, water is absorbed from the floor surface. In this configuration, the water in the water absorbing body 43 is sucked into the separation tank 23 when approaching 46. The pre-projection 44 in pressure contact with the surface of the water absorbing body 43 serves to squeeze the water in the water absorbing body 43, and the post projection 44b slightly in contact with the surface of the water absorbing body 43 prevents the water from flowing back to the floor surface 13. Yes. 45 indicates a water droplet, arrow 30 indicates the flow of airflow, and arrow 40 indicates the direction of rotation of the rotary wiper 41.

(Example 3)
A third embodiment of the present invention will be described with reference to FIGS. FIG. 8B is an enlarged view of the rotary wiper 51, and FIG. 9 is a partial cross-sectional view of the suction port 12 as viewed from the front. A water tank 52 is installed inside the rotary wiper 51 by a communication pipe 50 and is connected to a water supply pipe 54 having a large number of dripping ports 53 on the lower side. The water supply pipe 54 is fixed and does not rotate, and the rotary wiper 51 can rotate. 51 a is a rubber lip installed on the outer periphery of the rotary wiper 51 for wiping the floor surface, and 55 is a mist outlet 55 provided on the outer periphery of the rotary wiper 51. When the rotating wiper 51 is rotating, if the water droplet 53a falls from the dropping port 53 as indicated by an arrow 53b, the water droplet 53a is repelled by the inner wall 51b of the rotating wiper and sprayed at the same time. It is discharged as mist. As described in the above embodiment, the mist dissolves the dirt on the floor surface 13, and the melted dirt is easily peeled off from the floor surface 13 by the rotary wiper 51 and sucked from the water inlet 56. The arrow 60 indicates the flow of mist discharged from the outer periphery of the rotary wiper 51, the arrow 60a indicates the flow of airflow containing dirt dissolved in moisture, and the arrow 60b indicates the flow of airflow after the moisture 38 is separated.
[0026]
FIG. 10A shows an example in which a porous body 57 such as a sponge is wound around the outer periphery of a rotating wiper 51 having a large number of discharge ports 55. Mist is discharged from the porous body 57 to the outside by centrifugal force. At the same time as the dirt is dissolved, the porous body 57 peels off the dirt, and is sucked from the water inlet 56 together with the air flow. This method works in the same way as a wet cloth, and can effectively remove dirt on the floor surface 13.
[0027]
Further, a water supply tank 52 may be installed in the rotary wiper 51 as shown in FIG. In this case, the discharge port 55a also serves as a dropping port, and the configuration of the entire suction port 12 is simplified. An arrow 60a indicates a flow of airflow including dirt dissolved in moisture, and an arrow 60b indicates a flow of airflow after the moisture 38 is separated.
[0028]
As shown in FIG. 10, the inlet 64 provided with the opening / closing lid A65 is provided in the separation tank 23, the opening / closing lid B66 is also provided at the outlet 42a of the communication pipe 42, and the opening / closing lid A is closed when cleaning with water. If the opening / closing lid B is opened during general cleaning, an appropriate flow rate is selected for each cleaning, and the cleaning performance is improved.
