Description

本発明は、真空掃除機に関し、詳細には水掃除機能を備えた真空掃除機に関する。   The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner having a water cleaning function.

一般に、水掃除の機能を備えた真空掃除機は、被掃除面に水気のない状態でゴミなどの異物を吸い込んで掃除を行う一般掃除と、被掃除面、特に床、大理石などの固い表面に水をかけ被掃除面の染みなどを拭き取って水と共にゴミを吸込む水掃除とを選択的に行う掃除機のことを指す。   In general, vacuum cleaners equipped with a water cleaning function are generally used for cleaning by sucking in foreign matter such as dust while the surface to be cleaned is damp, and for surfaces to be cleaned, especially floors, marble, and other hard surfaces. It refers to a vacuum cleaner that selectively performs water cleaning by wiping off stains on the surface to be cleaned by applying water and sucking dust together with water.

係る水掃除の機能を有する真空掃除機は、水タンクと水吐出弁および水吐出ノズルから構成され、被掃除面に水を吐出す水吐出ユニットと、被掃除面を擦って染みなどを拭き取るブラシとを含む。従って、水掃除を行う場合、真空掃除機は被掃除面に水を吐出し、ブラシで被掃除面を拭きとってから染みなどを除去し、ブラシにより除去された染みなどと共に吐出された水を吸込む。   The vacuum cleaner having a water cleaning function is composed of a water tank, a water discharge valve, and a water discharge nozzle, and includes a water discharge unit that discharges water onto the surface to be cleaned, and a brush that rubs the surface to be cleaned to wipe off stains and the like. Including. Therefore, when performing water cleaning, the vacuum cleaner discharges water to the surface to be cleaned, wipes the surface to be cleaned with a brush, removes stains, etc., and removes water discharged together with stains removed by the brush. Inhale.

しかし、一般掃除を行う場合このブラシは、ゴミなどがゴミ吸入口に吸込まれることを妨害してしまう。これを解決するために、従来にはブラシと被掃除面との間の間隔を調整した。即ち、一般掃除を行う際にはブラシを被掃除面から離隔させることでゴミなどを円滑に吸込むようにし、水掃除を行う際にはブラシが被掃除面と接して擦ることができるように構成した。従って、従来の水掃除機能を備えた真空掃除機はブラシを上下に上昇および下降させることのできる機構がさらに必要であったので、ブラシ組立体の構造がさらに複雑になる問題点を抱えた。   However, when general cleaning is performed, this brush prevents dust and the like from being sucked into the dust inlet. In order to solve this, conventionally, the distance between the brush and the surface to be cleaned has been adjusted. That is, when performing general cleaning, the brush is separated from the surface to be cleaned so that dust can be sucked in smoothly, and when cleaning with water, the brush can be rubbed against the surface to be cleaned. did. Accordingly, the conventional vacuum cleaner having the water cleaning function further requires a mechanism that can raise and lower the brush up and down, and thus has a problem that the structure of the brush assembly is further complicated.

さらに、被掃除面を水掃除する場合に、先ず、ブラシが被掃除面と離隔された状態でゴミなどを吸込む一般掃除を行った後、それからブラシを下降させた状態で水をかけ被掃除面を拭き取るとった過程を行なわなければならないことから、掃除時間が一般掃除のみを行う場合に比べてほぼ２倍かかってしまう問題点も抱えている。   Furthermore, when cleaning the surface to be cleaned with water, first perform general cleaning in which dust is sucked in a state where the brush is separated from the surface to be cleaned, and then the surface to be cleaned is sprayed with water while the brush is lowered. Since the process of wiping off must be performed, there is also a problem that the cleaning time is almost twice as long as the case of performing only general cleaning.

また、水掃除の完了後、水供給弁を遮断しても水供給弁と水吐出ノズルとの間に残留した水が水吐出ノズルから流れる恐れがあり、これにより真空掃除機の周りを汚してしまう不具合がある。   In addition, after the water cleaning is completed, even if the water supply valve is shut off, water remaining between the water supply valve and the water discharge nozzle may flow from the water discharge nozzle. There is a problem.

本発明は前述した問題点を解決するために案出されたもので、本発明の目的は、ブラシを上昇／下降させる必要がないため、構造の簡単な水掃除機能を有する真空掃除機を提供することにある。   The present invention has been devised to solve the above-mentioned problems, and an object of the present invention is to provide a vacuum cleaner having a simple water cleaning function because it is not necessary to raise / lower the brush. There is to do.

また、ゴミを吸込みながらも水掃除が同時に行われるため、水掃除の際に掃除時間の短縮が図れる水掃除機能を備えた真空掃除機を提供することにある。   Another object of the present invention is to provide a vacuum cleaner having a water cleaning function capable of shortening the cleaning time during water cleaning because water cleaning is simultaneously performed while sucking in dust.

本発明の目的は、本体と、被掃除面と向かい合うゴミ吸入口と、前記被掃除面と接して回転すべく前記ゴミ吸入口に設けられたブラシと水を吐き出す水吐出ノズルと、を含み、前記ゴミ吸入口が前記本体と連通されるよう設けられたブラシ組立体と、前記ブラシ組立体の下面に前記ブラシの前方および後方に前記被掃除面との摩擦により選択的にゴミ吸入経路を開放したり遮断する前方および後方遮断部材とを含む水掃除機能を備えた真空掃除機を提供することにより達成される。   The object of the present invention includes a main body, a dust inlet facing the surface to be cleaned, a brush provided in the dust inlet to rotate in contact with the surface to be cleaned, and a water discharge nozzle for discharging water, A brush assembly provided so that the dust suction port communicates with the main body, and a dust suction path is selectively opened on the lower surface of the brush assembly by friction with the cleaning surface in front of and behind the brush. This is accomplished by providing a vacuum cleaner with a water cleaning function that includes front and rear blocking members that act or block.

この時、前記前方遮断部材と前記後方遮断部材のうちいずれかが前記ゴミ吸入経路を開放すると、残り１つは前記ゴミ吸入経路を遮断することが好ましい。即ち、前記前方遮断部材は前記ブラシ組立体が前進すれば、前記ゴミ吸入経路を開放するよう形成されることが好ましい。   At this time, when one of the front blocking member and the rear blocking member opens the dust suction path, the remaining one preferably blocks the dust suction path. That is, it is preferable that the front blocking member is formed to open the dust suction path when the brush assembly moves forward.

なお、前記前方遮断部材は、前記ブラシ組立体の下面に前記ブラシの前方に前記被掃除面との摩擦により所定の角度旋回できるよう設けられ、旋回角度に応じてゴミ吸入経路を開放したり遮断するように形成される。この時、前記前方遮断部材は、前記ブラシ組立体前方のゴミ吸入経路を遮断し、板状に形成された遮断板と、前記遮断板の両側に形成され、前記ブラシ組立体に回転自在に組立てられた回転軸と、前記遮断板の一面に扇形に形成され、前記扇形の円弧部が前記遮断板の先端から延びるべく形成された回転突起とを含み、前記扇形の円弧部が前記被掃除面と接すると、前記遮断板の先端が前記被掃除面と離隔されることが好ましい。   The front blocking member is provided on the lower surface of the brush assembly so as to be turned at a predetermined angle by friction with the surface to be cleaned in front of the brush, and opens or blocks the dust suction path according to the turning angle. To be formed. At this time, the front blocking member blocks the dust suction path in front of the brush assembly, is formed on a plate-shaped blocking plate and on both sides of the blocking plate, and is rotatably assembled to the brush assembly. A rotating shaft formed in a fan shape on one surface of the blocking plate, and the fan-shaped arc portion is formed to extend from a tip of the blocking plate, and the fan-shaped arc portion is the surface to be cleaned. It is preferable that the tip of the shielding plate is separated from the surface to be cleaned.

さらに、前記後方遮断部材は、前記ブラシ組立体に形成された後方遮断部材の収納溝に固定される頭部と、一面は平面であり、他面は複数の突起が一定の間隔で連続的に形成された突起面から形成され、前記ブラシ組立体の進行方向によって平面あるいは突起面の先端一部が選択的に前記被掃除面に押される遮断部とを含む。   Further, the rear blocking member includes a head fixed to a receiving groove of the rear blocking member formed in the brush assembly, one surface is a flat surface, and the other surface is continuously provided with a plurality of protrusions at a constant interval. A blocking portion that is formed from the formed protruding surface and is selectively pressed against the surface to be cleaned by a flat surface or a tip of the protruding surface depending on the traveling direction of the brush assembly.

また、前記ブラシ組立体は、前記水吐出ノズルに空気の含んだ水を吐出すためのエアーポンプを更に含む。   The brush assembly further includes an air pump for discharging water containing air to the water discharge nozzle.

そして、前記水吐出ノズルは、前記ブラシ組立体の全面に少なくとも１つ設けられることが好ましい。   It is preferable that at least one water discharge nozzle is provided on the entire surface of the brush assembly.

そして、水掃除機能を備えた真空掃除機は、前記本体に設けられ、一般掃除と水掃除のいずれかを選択するモードスイッチと、前記モードスイッチが水掃除に選択されれば前記エアーポンプを選択的に動作させ前記水吐出ノズルに水が吐出されるようにするポンプスイッチを更に含む。   A vacuum cleaner having a water cleaning function is provided in the main body, and selects a mode switch for selecting either general cleaning or water cleaning, and if the mode switch is selected for water cleaning, selects the air pump. And a pump switch that is operated in a normal manner so that water is discharged to the water discharge nozzle.

さらに、水掃除機能を備えた真空掃除機は、前記ブラシ組立体の下面に前記後方遮断部材の裏側に設けられ、前記被掃除面を殺菌する紫外線ランプを更に含む。なお、前記紫外線ランプの前面にはテープロンカバーが設けられていることが好ましい。   Further, the vacuum cleaner having a water cleaning function further includes an ultraviolet lamp provided on the lower surface of the brush assembly on the back side of the rear blocking member and sterilizing the surface to be cleaned. A taperon cover is preferably provided on the front surface of the ultraviolet lamp.

本発明に係る水掃除機能を備えた真空掃除機によると、前方および後方遮断部材によりゴミ吸入経路を開放または遮断するので、ブラシを上昇／下降せずに済む。さらに、前述の前方および後方遮断部材も被掃除面との摩擦により動作することから別の駆動要素を必要としない。従って、本発明によると、従来の水掃除機能を備えた真空掃除機に比べてその構造が極めて簡単な水掃除機能を有する真空掃除機が提供できる。   According to the vacuum cleaner having the water cleaning function according to the present invention, the dust suction path is opened or blocked by the front and rear blocking members, so that it is not necessary to raise / lower the brush. Furthermore, since the front and rear blocking members described above operate due to friction with the surface to be cleaned, no separate driving elements are required. Therefore, according to the present invention, it is possible to provide a vacuum cleaner having a water cleaning function whose structure is extremely simple compared to a conventional vacuum cleaner having a water cleaning function.

また、本発明による水掃除機能を備えた真空掃除機は、ブラシで被掃除面の染みを拭き取る水掃除を行う場合にも、ゴミ吸入経路が開放されることからゴミと共に吸込むことができる。即ち、本発明による水掃除機能を備えた真空掃除機は、被掃除面に存在するゴミを取除くために、先に一般掃除を行ってから再び水掃除を行う必要がないため、従来の水掃除機能を備えた真空掃除機に比べてその時間を短縮できる。   In addition, the vacuum cleaner having the water cleaning function according to the present invention can suck in with dust because the dust suction path is opened even when cleaning the surface of the surface to be cleaned with a brush. That is, the vacuum cleaner having the water cleaning function according to the present invention does not need to perform general cleaning first and then perform water cleaning again in order to remove dust existing on the surface to be cleaned. The time can be shortened compared to a vacuum cleaner with a cleaning function.

さらに、本発明による水掃除機能を備えた真空掃除機は、水掃除を完了しエアーポンプを停止させた場合、エアポンプと水吐出ノズルとの間の水吐出ホスに残留した水が空気により遮断されるので、水が水吐出ノズルから流れ出ることはない。よって、本発明に係る水掃除機機能を備えた真空掃除機は、残水により真空掃除機の周りを汚さない。   Furthermore, in the vacuum cleaner having the water cleaning function according to the present invention, when the water cleaning is completed and the air pump is stopped, the water remaining in the water discharge phos between the air pump and the water discharge nozzle is blocked by the air. Therefore, water does not flow out from the water discharge nozzle. Therefore, the vacuum cleaner provided with the water cleaner function according to the present invention does not stain the periphery of the vacuum cleaner with the remaining water.

以下、添付の図面に基づいて本発明の好適な実施形態を詳述する。

The water cleaning mode is set so that power is supplied to all of the motor of the motor assembly, the brush motor 62, and the air pump 72. Accordingly, when the power switch is turned on, the motor of the motor assembly and the brush motor 62 rotate, and when the pump switch 17 is turned on, the air pump 72 operates and water is discharged from the water discharge nozzle 74.

図３および図４に示したように、ブラシ組立体２０は、ブラシ胴体２１、吸入ダクト３０、前方および後方遮断部材４０、５０、ブラシユニット６０、水吐出ユニット７０、複数の輪８１，８２、および紫外線ランプ９０（図７参照）を有する。   As shown in FIGS. 3 and 4, the brush assembly 20 includes a brush body 21, a suction duct 30, front and rear blocking members 40 and 50, a brush unit 60, a water discharge unit 70, a plurality of rings 81 and 82, And an ultraviolet lamp 90 (see FIG. 7).

ブラシ胴体２１は、その下面の前部に被掃除面からゴミおよび異物を吸込むことのできるゴミ吸入口２２が形成され、後述する他の構成要素を支持する。   The brush body 21 is formed with a dust inlet 22 through which a dust and foreign matter can be sucked from the surface to be cleaned at the front part of the lower surface thereof, and supports other components to be described later.

吸入ダクト３０はブラシ胴体２１の上部に設けられ、一端はゴミ吸入口２２と連結されており、他端３１は本体１０のホス１３（図１参照）と連結される。従って、吸入ダクト３０は、ゴミ吸入口２２から吸込まれるゴミと水がホス１３を介して本体１０のゴミ収集筒に回収される移動経路をなす。   The suction duct 30 is provided in the upper part of the brush body 21, one end is connected to the dust suction port 22, and the other end 31 is connected to the phos 13 (see FIG. 1) of the main body 10. Therefore, the suction duct 30 forms a moving path in which dust and water sucked from the dust suction port 22 are collected in the dust collection cylinder of the main body 10 via the phos 13.

ブラシユニット６０は、ゴミ吸入口２２に回転自在に設けられるブラシ６１と、ブラシ６１を回転させるブラシモータ６２と、ブラシモータ６２の動力をブラシ６１へ伝達する動力伝達手段６３を含む。   The brush unit 60 includes a brush 61 that is rotatably provided in the dust suction port 22, a brush motor 62 that rotates the brush 61, and power transmission means 63 that transmits the power of the brush motor 62 to the brush 61.

ブラシ６１は、円筒状のブラシドラム６１ａとブラシ毛６１ｂからなる。ブラシドラム６１ａは、ゴミ吸入口２２の両端に設けられた軸受けのような回転支持要素６７により回転支持される。ブラシドラム６１ａの表面には複数のブラシ毛６１ｂが設けられる。複数のブラシ毛６１ｂは多様な方式で設置できるが、本実施の形態の場合は一定間隔を保って３列にブラシ毛６１ｂを配置した。それぞれのブラシ毛６１ｂの列は円弧形状をなす。さらに、ブラシ毛６１ｂの長さはブラシドラム６１ｂが回転する際、ブラシ毛６１ｂの先端が被掃除面を擦って通るよう形成することが好ましい。従って、ブラシ６１は水掃除時には被掃除面に取り付いた染みなどを擦りとって除去することができ、また、一般掃除の時には被掃除面のゴミなどがゴミ吸入口２２へ容易に吸込まれるよう援助する。   The brush 61 includes a cylindrical brush drum 61a and brush bristles 61b. The brush drum 61a is rotatably supported by a rotation support element 67 such as a bearing provided at both ends of the dust suction port 22. A plurality of brush bristles 61b are provided on the surface of the brush drum 61a. The plurality of brush bristles 61b can be installed in various ways, but in the case of the present embodiment, the bristles 61b are arranged in three rows at a constant interval. Each row of brush bristles 61b has an arc shape. Further, it is preferable that the length of the bristle 61b is formed so that the tip of the bristle 61b rubs through the surface to be cleaned when the brush drum 61b rotates. Therefore, the brush 61 can scrape and remove stains attached to the surface to be cleaned during water cleaning, and dust on the surface to be cleaned can be easily sucked into the dust inlet 22 during general cleaning. support.

動力伝達手段６３は、ブラシモータ６２とブラシ６１にそれぞれ設けられた２つのプーリー６５，６４を連結するベルト６６から構成される。従って、ブラシモータ６２が回転すれば、２つのプーリー６４，６５とベルト６６により、ブラシモータ６２の駆動力がブラシ６１に伝わりブラシ６１が回転される。   The power transmission means 63 includes a brush 66 connecting two pulleys 65 and 64 provided on the brush motor 62 and the brush 61, respectively. Therefore, when the brush motor 62 rotates, the driving force of the brush motor 62 is transmitted to the brush 61 by the two pulleys 64 and 65 and the belt 66, and the brush 61 is rotated.

前方遮断部材４０は、ブラシ胴体２１の下面にブラシ６１の前方に設けられ、ブラシ組立体２０前方のゴミがゴミ吸入口１１に吸込まれるゴミ吸入経路３（図７参照）を選択的に遮断するか開放する。前方遮断部材４０の一例が図５に示されている。同図に示したように、前方遮断部４０は遮断板４１、２つの回転軸４２、および２つの回転突起４３からなり、ゴムで形成される。   The front blocking member 40 is provided in front of the brush 61 on the lower surface of the brush body 21, and selectively blocks the dust suction path 3 (see FIG. 7) in which dust in front of the brush assembly 20 is sucked into the dust suction port 11. Do or release. An example of the front blocking member 40 is shown in FIG. As shown in the figure, the front blocking portion 40 includes a blocking plate 41, two rotating shafts 42, and two rotating protrusions 43, and is formed of rubber.

遮断板４１は、ブラシ組立体２０前方のゴミがゴミ吸入口２２に吸込まれる前方ゴミ吸入経路３を遮断し、板状に形成されている。なお、遮断板４１の高さは、遮断板４１が被掃除面２（図７参照）と垂直した場合、遮断板４１の先端４１ａがやや押さえられる程度に形成することが好ましい。従って、遮断板４１が被掃除面２へ垂直位置になると、遮断板４１前方のゴミはゴミ吸入口２２に吸込まれない。回転軸４２は、遮断板４１の両側に形成され、ブラシ組立体２０のブラシ胴体２１に形成されたヒンジ溝（図示せず）に挿入されて前方遮断部材４０が所定の角度回転できるよう行う。なお、回転軸４２は、耐久性のために遮断板４１を貫通するステンレス棒で形成される。回転突起４３は遮断板４１の一面に扇形状で形成され、扇形の円弧部４３ａは遮断板４１の先端４１ａから円弧に延長されている。なお、扇形の円弧部４３ａは回転軸４２から遮断板先端４１ａまでを半径とする。回転突起４３は、遮断板４１一面の両終端に１つずつ２個を形成してその間にゴミを通らせる。この時、回転突起４３の円弧角（θ）は、図８に示したように、回転突起４３の一側面４４が垂直に位置する場合、遮断板４１の先端４１ａがブラシ胴体２１の下面に近接して位置することが好ましい。従って、ブラシ組立体２０が遮断板４１の回転突起４３が突設された方向へと移動すれば、前方遮断部材４０は被掃除面２との摩擦によりブラシ組立体２０の移動方向の逆方向へ所定の角度回転される。すると、遮断板４１と両側の回転突起４３との間にゴミ吸入経路３が開放される。ブラシ組立体２０が逆方向に移動すれば、前方遮断部材４０は被掃除面２との摩擦により、遮断板４１が被掃除面２に垂直状態になってゴミ吸入経路３を遮断する（図９参照）。従って、前方遮断部材４０の回転突起４３がブラシ組立体２０に組みつけられる方向に従ってブラシ組立体２０がいずれかの方向に移動したとき、前方遮断部材２０はゴミ吸入経路３の開放あるいは遮断を行う。例えば、本発明の実施の形態のように回転突起４３がブラシ組立体２０の前方に向かって前方遮断部材４０が設けられた場合（図７参照）、ブラシ組立体２０が前進すれば前方のゴミ吸入経路３は開放され、ブラシ組立体２０が後進すれば前方のゴミ吸入経路３は遮断される。   The blocking plate 41 blocks the front dust suction path 3 through which dust in front of the brush assembly 20 is sucked into the dust suction port 22 and is formed in a plate shape. In addition, it is preferable to form the height of the shielding plate 41 so that the tip 41a of the shielding plate 41 is slightly pressed when the shielding plate 41 is perpendicular to the surface to be cleaned 2 (see FIG. 7). Therefore, when the shielding plate 41 is in a vertical position with respect to the surface to be cleaned 2, dust in front of the shielding plate 41 is not sucked into the dust suction port 22. The rotating shafts 42 are formed on both sides of the blocking plate 41 and inserted into hinge grooves (not shown) formed in the brush body 21 of the brush assembly 20 so that the front blocking member 40 can rotate by a predetermined angle. The rotating shaft 42 is formed of a stainless steel rod that penetrates the blocking plate 41 for durability. The rotation protrusion 43 is formed in a fan shape on one surface of the blocking plate 41, and the fan-shaped arc portion 43 a extends from the tip 41 a of the blocking plate 41 to an arc. The sector-shaped arc portion 43a has a radius from the rotating shaft 42 to the end of the shield plate 41a. Two rotating protrusions 43 are formed at both ends of the entire surface of the blocking plate 41 so that dust can pass between them. At this time, the arc angle (θ) of the rotating projection 43 is set so that the tip 41a of the blocking plate 41 is close to the lower surface of the brush body 21 when one side 44 of the rotating projection 43 is positioned vertically as shown in FIG. Are preferably located. Accordingly, when the brush assembly 20 moves in the direction in which the rotation protrusion 43 of the blocking plate 41 is provided, the front blocking member 40 moves in a direction opposite to the moving direction of the brush assembly 20 due to friction with the surface 2 to be cleaned. It is rotated by a predetermined angle. Then, the dust suction path 3 is opened between the blocking plate 41 and the rotating protrusions 43 on both sides. When the brush assembly 20 moves in the opposite direction, the front blocking member 40 is brought into a state perpendicular to the surface to be cleaned 2 by the friction with the surface 2 to be cleaned, thereby blocking the dust suction path 3 (FIG. 9). reference). Therefore, when the brush assembly 20 moves in any direction according to the direction in which the rotary protrusion 43 of the front blocking member 40 is assembled to the brush assembly 20, the front blocking member 20 opens or blocks the dust suction path 3. . For example, when the front blocking member 40 is provided with the rotation protrusion 43 toward the front of the brush assembly 20 as in the embodiment of the present invention (see FIG. 7), the dust in the front of the brush assembly 20 moves forward. The suction path 3 is opened, and when the brush assembly 20 moves backward, the front dust suction path 3 is blocked.

後方遮断部材５０は、ブラシ胴体２１の下面にブラシ６１、即ち、ゴミ吸入口２２の後方に設けられ、ゴミ吸入口２２後方のゴミがゴミ吸入口２２に吸込まれるゴミ吸入経路４を選択的に遮断するか開放する。後方遮断部材５０の一例が図６に示されている。後方遮断部材５０は頭部５１と遮断部５２から構成される。頭部５１は、ブラシ組立体２０のブラシ胴体２１に形成された後方遮断部材の収納溝５７（図８参照）に固定される。遮断部５２の一面５３は平面であり、反対面５４は複数の突起５５が一定間隔で連続形成された突起面である。この時、突起面５４は三角状を有するラックギヤ状で形成することが好ましい。さらに、遮断部５２の高さはブラシ組立体２０が被掃除面２に位置する場合、遮断部５２の先端５２ａが被掃除面２にやや押される程度で形成される。すると、ブラシ組立体２０が前後に移動することにより後方遮断部材５０の先端５２ａが進行方向の逆方向に曲げた状態で被掃除面２と摩擦しながら移動される。従って、ブラシ組立体２０の進行方向によって平面５３あるいは突起面５４の先端部分が選択的に被掃除面２に押される。突起面５４が被掃除面２と接触すると、複数の突起５５との間の空間５６にゴミや水が吸込まれるため、ゴミ吸入口２２の後方のゴミ吸入経路４が開放される。従って、後方遮断部材５０の突起面５４がブラシ組立体２０に組立てられる方向に応じてブラシ組立体２０がいずれの方向に移動した時、後方遮断部材５０はゴミ吸入経路４の開放あるいは遮断を決める。例えば、本実施の形態のように、突起面５４がブラシ組立体２０の後方に向って後方遮断部材５０が設けられた場合（図７参照）、ブラシ組立体２０が後進すれば後方のゴミ吸入経路４は開放され、ブラシ組立体２０が前進すれば後方のゴミ吸入経路４は遮断される。   The rear blocking member 50 is provided on the lower surface of the brush body 21 at the back of the brush 61, that is, the dust suction port 22. Shut off or open. An example of the rear blocking member 50 is shown in FIG. The rear blocking member 50 includes a head 51 and a blocking unit 52. The head 51 is fixed to a storage groove 57 (see FIG. 8) of the rear blocking member formed in the brush body 21 of the brush assembly 20. One surface 53 of the blocking portion 52 is a flat surface, and the opposite surface 54 is a protrusion surface in which a plurality of protrusions 55 are continuously formed at a constant interval. At this time, the projecting surface 54 is preferably formed in a rack gear shape having a triangular shape. Further, the height of the blocking portion 52 is formed such that the tip 52 a of the blocking portion 52 is slightly pressed against the surface to be cleaned 2 when the brush assembly 20 is positioned on the surface to be cleaned 2. Then, when the brush assembly 20 moves back and forth, the tip 52a of the rear blocking member 50 is moved while rubbing against the surface 2 to be cleaned in a state bent in the direction opposite to the traveling direction. Accordingly, the front end portion of the flat surface 53 or the projection surface 54 is selectively pushed against the surface to be cleaned 2 depending on the traveling direction of the brush assembly 20. When the projection surface 54 comes into contact with the surface 2 to be cleaned, dust and water are sucked into the space 56 between the plurality of projections 55, so that the dust suction path 4 behind the dust suction port 22 is opened. Accordingly, when the brush assembly 20 moves in any direction according to the direction in which the projection surface 54 of the rear blocking member 50 is assembled to the brush assembly 20, the rear blocking member 50 determines whether the dust suction path 4 is opened or blocked. . For example, as in the present embodiment, when the rear blocking member 50 is provided with the projecting surface 54 facing the rear of the brush assembly 20 (see FIG. 7), if the brush assembly 20 moves backward, the rear dust suction The path 4 is opened, and the rear dust suction path 4 is blocked when the brush assembly 20 moves forward.

本実施の形態の場合には、ブラシ組立体２０が前進すれば、前方遮断部材４０は前方ゴミ吸入経路３を開放し、且つ後方遮断部材５０は後方ゴミ吸入経路４を遮断する。ブラシ組立体２０が後進すれば前方遮断部材４０は前方ゴミ吸入経路３を遮断し、且つ後方遮断部材５０は後方ゴミ吸入経路４を開放する。しかし、これは一例に過ぎず、ブラシ組立体２０が前進または後進する場合、前方および後方遮断部材４０，５０が前述と逆方向に動作することもできる。あるいは、ブラシ組立体２０が前進すると前方および後方遮断部材４０，５０はゴミ吸入経路３，４全てを開放し、後進するとゴミ吸入経路３，４全てを遮断するといった構成も行える。   In the present embodiment, when the brush assembly 20 moves forward, the front blocking member 40 opens the front dust suction path 3 and the rear blocking member 50 blocks the rear dust suction path 4. When the brush assembly 20 moves backward, the front blocking member 40 blocks the front dust suction path 3 and the rear blocking member 50 opens the rear dust suction path 4. However, this is only an example, and when the brush assembly 20 moves forward or backward, the front and rear blocking members 40 and 50 may operate in the opposite direction as described above. Alternatively, the front and rear blocking members 40 and 50 can open all the dust suction paths 3 and 4 when the brush assembly 20 moves forward, and can block all the dust suction paths 3 and 4 when the brush assembly 20 moves backward.

さらに、本発明の一実施の形態における前方および後方遮断部材４０、５０はそれぞれ異なる形状を有するが、同一形状のものを使用してもよい。   Furthermore, although the front and rear blocking members 40 and 50 in the embodiment of the present invention have different shapes, the same shape may be used.

水吐出ユニット７０は、水掃除の時に被掃除面２に水を吐き出すものであって、図３に示したように、水タンク（図示せず）、水供給ホス７１、エアーポンプ７２、水吐出ホス７３、水吐出ノズル７４から構成される。水タンクは、所定の水を格納し水吐出ノズル７４に水を供給するよう本体１０に設けられる。この時、水タンクは、水吐出ノズル７４より高い位置に設置することがよい。水供給ホス７１は水タンクとエアーポンプ７２とを連通させ、水タンクに格納された水をエアーポンプ７２に供給させる。   The water discharge unit 70 discharges water to the surface 2 to be cleaned during water cleaning. As shown in FIG. 3, a water tank (not shown), a water supply phos 71, an air pump 72, a water discharge It comprises a phos 73 and a water discharge nozzle 74. The water tank is provided in the main body 10 so as to store predetermined water and supply water to the water discharge nozzle 74. At this time, the water tank is preferably installed at a position higher than the water discharge nozzle 74. The water supply phos 71 communicates the water tank and the air pump 72 to supply water stored in the water tank to the air pump 72.

エアーポンプ７２は、水吐出ノズル７４から吐き出される水と空気とを混ぜる。空気の混じった水が水吐出ホス７３を介して外部に吐き出されば、水吐出が遮断された場合の水の表面張力により水吐出ホス７３に残っていた水は水吐出ノズル７４を介してブラシ組立体２０の外部に流れない。エアーポンプ７２は、電気モータにより回転され、カームの原理を用いて大気中の空気と水供給ホス７１から供給された水を混合／圧縮した後、水吐出ホス７３を介して排出する。なお、エアーポンプ７２の圧縮圧力は、ほぼ０.８〜１Ｋｇｆ／ｃｍ２である。さらに、ダイアフラム（ｄｉａｐｈｒａｇｍ）方式のエアーポンプ７２を使用することにより、水が逆流してもエアーポンプ７２に損傷を与えない。また、エアーポンプ７２は吐出される水量を電気的に制御できる。即ち、エアーポンプ７２に印加される電圧を調整することによって吐出される水の量を調整できる。なお、調整される水の吐出量はほぼ０〜８００ＣＣ／分である。エアーポンプ７２の水吐出量は手動でエアーポンプ７２に印加される電圧を調整できる吐出量制御部（図示せず）を設けることで調整できる。あるいは、吐出量制御部がブラシ胴体２１の進行方向に従ってエアーポンプ７２の水吐出量を相違に制御できるプログラムを吐出量制御部にて設定できる。そして、ブラシ胴体２１の下面にブラシ組立体２０の進行方向を検出できる方向センサー（図示せず）を設け、この方向センサーの信号によりエアーポンプ７２は水の吐出について設定することができる。係る形態のエアーポンプ７２は、ビデ、血圧計、水族館などでよく使われる。 The air pump 72 mixes water and air discharged from the water discharge nozzle 74. If water mixed with air is discharged to the outside through the water discharge phos 73, the water remaining in the water discharge phos 73 due to the surface tension of the water when the water discharge is blocked is brushed through the water discharge nozzle 74. It does not flow outside the assembly 20. The air pump 72 is rotated by an electric motor, mixes / compresses air in the atmosphere and water supplied from the water supply phos 71 using the principle of Calm, and then discharges it through the water discharge phos 73. Note that the compression pressure of the air pump 72 is approximately 0.8 to 1 kgf / cm 2 . Further, by using a diaphragm type air pump 72, the air pump 72 is not damaged even if water flows backward. The air pump 72 can electrically control the amount of water discharged. That is, the amount of water discharged can be adjusted by adjusting the voltage applied to the air pump 72. The adjusted water discharge rate is approximately 0 to 800 CC / min. The water discharge amount of the air pump 72 can be adjusted by providing a discharge amount control unit (not shown) that can manually adjust the voltage applied to the air pump 72. Alternatively, the discharge amount control unit can set a program that allows the discharge amount control unit to control the water discharge amount of the air pump 72 in accordance with the traveling direction of the brush body 21. Then, a direction sensor (not shown) capable of detecting the traveling direction of the brush assembly 20 is provided on the lower surface of the brush body 21, and the air pump 72 can set the discharge of water by a signal from the direction sensor. Such an air pump 72 is often used in bidets, blood pressure monitors, aquariums, and the like.

水吐出ノズル７４は、ブラシ胴体２１の前面にブラシ組立体２０の前方に向って水が吐出されるよう設けられる。水吐出ノズル７４は１つ設けてもよいが、図３に示したように２つ設けることが好ましい。水吐出ホス７３は、空気の混じった水が２つの水吐出ノズル７４とエアーポンプ７２を連通してエアーポンプ７２を経由し水吐出ノズル７４から吐出されるよう行う。   The water discharge nozzle 74 is provided on the front surface of the brush body 21 so that water is discharged toward the front of the brush assembly 20. One water discharge nozzle 74 may be provided, but two water discharge nozzles 74 are preferably provided as shown in FIG. The water discharge phos 73 performs such that water mixed with air is discharged from the water discharge nozzle 74 via the air pump 72 through the two water discharge nozzles 74 and the air pump 72.

輪８１、８２は、ブラシ胴体２１の裏側に設けられた１対の大型輪８１とブラシ胴体２１の下面に後方遮断部材５０の裏側に設けられた１対の小型輪８２のことである。   The wheels 81 and 82 are a pair of large wheels 81 provided on the back side of the brush body 21 and a pair of small wheels 82 provided on the back surface of the rear blocking member 50 on the lower surface of the brush body 21.

紫外線ランプ９０は、図４および図７に示したように、水掃除の完了された被掃除面２を消毒するため小型輪８２の裏側のブラシ胴体２１に設けられる。なお、紫外線ランプ９０の上側には紫外線ランプ９０から上側に放射された紫外線を最大下側に反射できるようにステンレスやアルミニウムから構成された反射板９３を設け、紫外線ランプ９０の下側には透明なテープロンからなっている保護窓９１を設ける。この保護窓９１は、プラスチックからなっている枠９２を射出するときに、紫外線の透過されるテープロンを一体に射出形成する方法で製造することが好ましい。   As shown in FIGS. 4 and 7, the ultraviolet lamp 90 is provided on the brush body 21 on the back side of the small wheel 82 in order to disinfect the surface 2 to be cleaned that has been cleaned with water. A reflective plate 93 made of stainless steel or aluminum is provided above the ultraviolet lamp 90 so that ultraviolet rays emitted upward from the ultraviolet lamp 90 can be reflected to the maximum lower side, and transparent below the ultraviolet lamp 90. A protective window 91 made of a simple taperon is provided. The protective window 91 is preferably manufactured by a method of integrally forming a taperon through which ultraviolet rays are transmitted when the frame 92 made of plastic is injected.

カバー２３には２つの水吐出ノズル７４が露出されるべく形成された２つの穴２４（図１参照）が設けられ、ブラシ胴体２１の上部に組立てられ、前述の構成要素が外部から見えないよう設ける。   The cover 23 is provided with two holes 24 (see FIG. 1) formed so that the two water discharge nozzles 74 are exposed, and is assembled on the upper part of the brush body 21 so that the above-described components cannot be seen from the outside. Provide.

以下、本発明に係る水掃除機能を有する真空掃除機１の作用について図１ないし図９に基づいて説明する。   Hereinafter, the operation of the vacuum cleaner 1 having a water cleaning function according to the present invention will be described with reference to FIGS.

先ず、本発明に係る真空掃除機１の水掃除を行う場合について説明する。   First, the case where the vacuum cleaner 1 which concerns on this invention performs water cleaning is demonstrated.

水掃除を行う場合、電源スイッチ１５をオンさせ、ハンドル１１に設けられたモードスイッチ１６を水掃除モードに切替える。それから、ポンプスイッチ１７をオンさせて２つの水吐出ノズル７４から水がブラシ組立体２０の前方に向って吐出されるようにする。ポンプスイッチ１７がオンされれば、エアーポンプ７２が動作する。エアーポンプ７２は水供給ホス７１を介して供給される水に大気から吸入された空気を混合し水吐出ホス７３に排出する。すると、２つの水吐出ノズル７４を介して空気の混った水が吐出される。なお、水吐出ホス７３には水と空気が交互に流れる状態となる。従って、エアーポンプ７２が動作するときには水が連続的に吐出されるが、エアーポンプ７２が停止すると水吐出ホス７３に存在する空気が水の流れを妨害し、水吐出ノズル７４とエアーポンプ７２との間に残留する水が水吐出ノズル７４から流れることを抑える。さらに、必要な場合には、エアーポンプ７２の吐出量を調整することで吐出される水の量を適切に調節できる。   When performing water cleaning, the power switch 15 is turned on, and the mode switch 16 provided on the handle 11 is switched to the water cleaning mode. Then, the pump switch 17 is turned on so that water is discharged from the two water discharge nozzles 74 toward the front of the brush assembly 20. If the pump switch 17 is turned on, the air pump 72 operates. The air pump 72 mixes the air supplied from the atmosphere with the water supplied via the water supply phos 71 and discharges it to the water discharge phos 73. Then, water mixed with air is discharged through the two water discharge nozzles 74. The water discharge phos 73 is in a state where water and air flow alternately. Accordingly, water is continuously discharged when the air pump 72 is operated, but when the air pump 72 is stopped, the air present in the water discharge phosph 73 obstructs the flow of water, and the water discharge nozzle 74 and the air pump 72 In this case, the remaining water is prevented from flowing from the water discharge nozzle 74. Furthermore, if necessary, the amount of water discharged can be appropriately adjusted by adjusting the discharge amount of the air pump 72.

ブラシ組立体２０前方の被掃除面２に水が吐出されると、ユーザはハンドル１１をもってブラシ組立体２０を前進および後進させる。すると、前方および後方遮断部材４０、５０、モータ組立体のモータ、およびブラシユニット６０のブラシモータ６２が動作され、ゴミと共に水を吸入しゴミ収集筒に収集する。   When water is discharged to the surface to be cleaned 2 in front of the brush assembly 20, the user moves the brush assembly 20 forward and backward with the handle 11. Then, the front and rear blocking members 40 and 50, the motor of the motor assembly, and the brush motor 62 of the brush unit 60 are operated to suck water together with the dust and collect it in the dust collecting cylinder.

なお、前方および後方遮断部材４０、５０の動作について説明すると次の通りである。   The operation of the front and rear blocking members 40, 50 will be described as follows.

ブラシ組立体２０が被掃除面２上にあるとき、前方および後方遮断部材４０、５０の先端４１ａ、５２ａはブラシ組立体２０の自重により押された状態である。この状態でブラシ組立体２０が前進すると、前方遮断部材４０は、回転軸４２を中心に回転突起４３が被掃除面２に接した状態を保ちながら逆時計回り（図８における矢印Ａ）に回転する。すると、前方遮断部材４０の回転量が増加するにつれ遮断板４１の先端４１ａと被掃除面２との間の間隔が次第に広がる。図８に示したように、回転突起４３の一側面４４が被掃除面２について垂直な状態であれば遮断板の先端４１ａが最大の高さに位置するので、ゴミ吸入口２２前方のゴミ吸入経路３は完全に開放される。さらに、ブラシ組立体２０が前進する時、後方遮断部材５０は遮断部５２の先端５２ａがブラシ組立体２０の後方へと曲がった状態になる。なお、遮断部５２の前面５３は平板であって、ゴミ吸入口２２後方のゴミ吸入経路４は遮断される。従って、ゴミ吸入口２２の裏側からゴミが吸込まれることが遮断される。このようにブラシ組立体２０が前進する場合、前方遮断部材４０により前方ゴミ吸入経路３が開放され、後方遮断部材４０により後方ゴミ吸入経路４が遮断されることから、本発明に係る真空掃除機１は空気と共にブラシ組立体２０の前方に吐出された水と水気のゴミを効率よく吸込むことができる。   When the brush assembly 20 is on the surface to be cleaned 2, the front ends 41 a and 52 a of the front and rear blocking members 40 and 50 are pressed by the weight of the brush assembly 20. When the brush assembly 20 moves forward in this state, the front blocking member 40 rotates counterclockwise (arrow A in FIG. 8) while maintaining the state where the rotation protrusion 43 is in contact with the surface to be cleaned 2 around the rotation shaft 42. To do. Then, as the amount of rotation of the front blocking member 40 increases, the distance between the tip 41a of the blocking plate 41 and the surface to be cleaned 2 gradually increases. As shown in FIG. 8, if one side 44 of the rotation protrusion 43 is perpendicular to the surface to be cleaned 2, the tip 41 a of the blocking plate is positioned at the maximum height, so that the dust suction in front of the dust suction port 22 is performed. Path 3 is completely open. Further, when the brush assembly 20 advances, the rear blocking member 50 is in a state where the tip 52a of the blocking portion 52 is bent toward the rear of the brush assembly 20. The front surface 53 of the blocking portion 52 is a flat plate, and the dust suction path 4 behind the dust suction port 22 is blocked. Accordingly, the suction of dust from the back side of the dust suction port 22 is blocked. In this way, when the brush assembly 20 moves forward, the front dust suction path 3 is opened by the front blocking member 40 and the rear dust suction path 4 is blocked by the rear blocking member 40. Therefore, the vacuum cleaner according to the present invention. 1 can efficiently suck in water and water discharged to the front of the brush assembly 20 together with air.

ユーザがブラシ組立体２０を後進させると、前方遮断部材４０は回転軸４２を中心に回転突起４３が被掃除面２に接した状態を保ちながら時計回りに回転する（図９参照）。すると、前方遮断部材４０の回転量が増加するにつれ遮断板４１の先端４１ａが次第に下がりゴミ吸入経路３を遮断する。図９に示したように、遮断板４１が被掃除面２について垂直な状態であれば前方のゴミ吸入経路３は完全に遮断される。さらに、後方遮断部材５０は遮断部５２の先端５２ａがブラシ組立体２０の前方へと曲がった状態になる。なお、遮断部５２の後面５４は突起面であり、ゴミ吸入口２２後方は遮断部５２の突起面５４の複数突起５５との間の空間を介してゴミ吸入口２２と連通される。従って、後方ゴミ吸入経路４が開放された状態となる。このようにブラシ組立体２０が後進する場合、ブラシ組立体２０を前進させた後にも被掃除面２に残留している水気を主に吸込んで除去する。   When the user moves the brush assembly 20 backward, the front blocking member 40 rotates clockwise around the rotation shaft 42 while keeping the rotation protrusion 43 in contact with the surface to be cleaned 2 (see FIG. 9). Then, as the amount of rotation of the front blocking member 40 increases, the tip 41a of the blocking plate 41 gradually falls to block the dust suction path 3. As shown in FIG. 9, the front dust suction path 3 is completely blocked if the blocking plate 41 is perpendicular to the surface 2 to be cleaned. Further, the rear blocking member 50 is in a state where the tip 52 a of the blocking portion 52 is bent forward of the brush assembly 20. The rear surface 54 of the blocking portion 52 is a protruding surface, and the rear of the dust suction port 22 communicates with the dust suction port 22 via a space between the plurality of protrusions 55 of the protruding surface 54 of the blocking portion 52. Accordingly, the rear dust suction path 4 is opened. When the brush assembly 20 moves backward as described above, water remaining on the surface to be cleaned 2 is mainly sucked and removed after the brush assembly 20 is moved forward.

さらに、電源スイッチ１５がオンされれば、ブラシモータ６２も共に回転される。ブラシモータ６２が回転されれば、プーリー６４，６５とベルト６６（図３参照）を介してブラシモータ６２の回転力の受けたブラシ６１も共に回転される。ブラシ６１が回転すれば、ブラシ毛６１ｂが被掃除面２を擦りながら回転するので、水気のある被掃除面２に取り付いた染みなどを効率よく除去できる。また、ブラシ毛６１ｂは、ブラシ６１の回転方向に向って凹んだ円弧状（図４参照）に設けられているため、被掃除面２から取除かれたゴミと水をゴミ吸入口２２へ効果的に押し入れることができる。   Further, when the power switch 15 is turned on, the brush motor 62 is also rotated. When the brush motor 62 is rotated, the brush 61 that receives the rotational force of the brush motor 62 via the pulleys 64 and 65 and the belt 66 (see FIG. 3) is also rotated. If the brush 61 rotates, the bristles 61b rotate while rubbing the surface to be cleaned 2, so that stains attached to the surface 2 to be cleaned can be efficiently removed. Further, since the bristle 61b is provided in an arc shape (see FIG. 4) that is recessed in the rotation direction of the brush 61, the dust and water removed from the surface to be cleaned 2 are effectively applied to the dust suction port 22. Can be pushed in.

以上、前述した通りに、ブラシ組立体２０を前進あるいは後進させることによって前方遮断部材４０および後方遮断部材５０が選択的にゴミ吸入経路３，４を開放あるいは遮断し、ブラシ６１が被掃除面２を擦りながら回転することによって被掃除面２に存在するゴミと水が効率よく取除かれることについて説明した。   As described above, when the brush assembly 20 is moved forward or backward, the front blocking member 40 and the rear blocking member 50 selectively open or block the dust suction paths 3 and 4, and the brush 61 is cleaned 2. It has been described that the dust and water present on the surface to be cleaned 2 are efficiently removed by rotating while rubbing.

次に、本発明に係るシンク掃除機１の一般掃除を行う場合について説明する。   Next, the case of performing general cleaning of the sink cleaner 1 according to the present invention will be described.

ユーザはハンドル１１に設けられたモードスイッチ１６を一般掃除モードに切替える。それから、電源スイッチ１５を押すと、本体１０に設けられたモータ組立体が動作し吸入力が発生する。すると、吸入力によりブラシ組立体２０のゴミ吸入口２２から被掃除面２のゴミが吸込まれゴミ収集筒に収納される。この際、ブラシモータ６２も動作しゴミ吸入口２２に設けられたブラシ６１を回転させる。即ち、一般の真空掃除機と同様に被掃除面２のゴミを吸込むことで掃除を行う。但し、ブラシ組立体２０を前進あるいは後進させることによって前方および後方遮断部材４０、５０が選択的に動作されることが違うところである。即ち、ブラシ組立体２０が前進すれば、前方遮断部材４０が所定の角度回転して前方ゴミ吸入経路３を開放し、後方遮断部材５０の先端５２ａがゴミ吸入口２２の反対側に曲がった状態となって後方ゴミ吸入経路４を遮断する。一方、ブラシ組立体２０が後進すれば、前方遮断部材４０が逆方向に所定の角度回転し前方ゴミ吸入経路３を遮断し、後方遮断部材５０の先端５２ａはゴミ吸入クリ２２側に曲がった状態で後方ゴミ吸入経路４を開放する。   The user switches the mode switch 16 provided on the handle 11 to the general cleaning mode. Then, when the power switch 15 is pressed, the motor assembly provided in the main body 10 operates to generate suction input. Then, the dust on the surface 2 to be cleaned is sucked from the dust inlet 22 of the brush assembly 20 by the suction input and stored in the dust collecting cylinder. At this time, the brush motor 62 is also operated to rotate the brush 61 provided in the dust suction port 22. That is, cleaning is performed by sucking in dust on the surface to be cleaned 2 in the same manner as a general vacuum cleaner. However, the forward and backward blocking members 40 and 50 are selectively operated by moving the brush assembly 20 forward or backward. That is, when the brush assembly 20 moves forward, the front blocking member 40 rotates by a predetermined angle to open the front dust suction path 3, and the tip 52a of the rear blocking member 50 is bent to the opposite side of the dust suction port 22. Thus, the rear dust suction path 4 is blocked. On the other hand, when the brush assembly 20 moves backward, the front blocking member 40 rotates by a predetermined angle in the reverse direction to block the front dust suction path 3, and the tip 52a of the rear blocking member 50 is bent toward the dust suction chest 22 side. To open the rear dust suction path 4.

さらに、ブラシ胴体２１の下面に紫外線ランプ９０を設ける場合、紫外線が被掃除面２を照射するため、ブラシ組立体２０を移動させることにより被掃除面２は殺菌される。   Further, when the ultraviolet lamp 90 is provided on the lower surface of the brush body 21, since the ultraviolet ray irradiates the surface 2 to be cleaned, the surface 2 to be cleaned is sterilized by moving the brush assembly 20.

以上、図面に基づいて本発明の好適な実施形態を図示および説明してきたが本発明の保護範囲は、前述の実施形態に限定するものではなく、特許請求の範囲に記載された発明とその均等物にまで及ぶものである。   Although the preferred embodiments of the present invention have been illustrated and described with reference to the drawings, the protection scope of the present invention is not limited to the above-described embodiments, and the invention described in the claims and equivalents thereof are described.
