Description

本発明は、塵埃は勿論、塵埃を含む水等の液体も吸引可能な集塵機に関する。   The present invention relates to a dust collector capable of sucking not only dust but also liquid such as water containing dust.

図３は、従来の集塵機の縦断面図で、集塵機１は、上面を開口したタンク２の上方に、吸気ユニット４を内蔵した本体３を設けてなる。吸気ユニット４は、タンク２の開口を閉塞して本体３を支持するタンクカバー５によって、タンク２の中央上方から吊り下げ支持されており、内部に、モータ７と、そのモータ７の駆動で回転する吸込ファン８とを内蔵している。また、タンクカバー５には、吸込ファン８の真下で吸気ユニット４の下面に開口する吸気口９，９・・が形成されている。６は、本体３の上部を覆うカウリングで、側面には運転スイッチ１０が設けられている。１１は、タンク２の側面に設けられてホースやノズル等を接続する吸込口である。
さらに、吸気ユニット４の下方には、フロート１３を上下動可能に収容したフロートケージ１２が連結されている。このフロート１３は、タンク２内に貯留する水等の液体の水位に合わせて上下動し、上限位置では、フロート１３の上面が吸気口９の周囲で下向きに突設された筒部に当接して吸気口９を閉塞するようになっている。 FIG. 3 is a longitudinal sectional view of a conventional dust collector. The dust collector 1 is provided with a main body 3 containing an intake unit 4 above a tank 2 having an upper surface opened. The intake unit 4 is supported by being suspended from the upper center of the tank 2 by a tank cover 5 that closes the opening of the tank 2 and supports the main body 3, and rotates inside by a motor 7 and driving of the motor 7. A suction fan 8 is built in. Further, the tank cover 5 is formed with intake ports 9, 9... That open to the lower surface of the intake unit 4 directly below the suction fan 8. 6 is a cowling which covers the upper part of the main body 3, and the operation switch 10 is provided in the side surface. A suction port 11 is provided on the side surface of the tank 2 to connect a hose, a nozzle, or the like.
Further, a float cage 12 that accommodates the float 13 so as to be movable up and down is connected to the lower side of the intake unit 4. The float 13 moves up and down in accordance with the level of liquid such as water stored in the tank 2, and at the upper limit position, the upper surface of the float 13 comes into contact with a cylindrical portion protruding downward around the air inlet 9. Thus, the intake port 9 is closed.

よって、運転スイッチ１０のＯＮ操作でモータ７が駆動して吸込ファン８が回転すると、吸込口１１に接続したホース等を介して外気がタンク２内に吸引され、吸気口９を通って吸込ファン８によりカウリング６内の送気路１４へ送られ、カウリング６下面の排気口１５から排出されるものとなる。ここで、タンク２内に水を吸引すると、フロート１３がタンク２内に貯留した水位の上昇に伴って上昇し、上限位置で吸気口９を閉塞して水の吸引を停止させることになる。１６は、タンクカバー５とタンク２の開口との間に挟持されて、吸込口１１と吸気ユニット４との間を袋形状で遮断する布製のフィルタで、吸込口１１から吸込まれる空気や水をここで濾過できるようになっている（その他、フロートを有する集塵機の例として特許文献１）。   Therefore, when the motor 7 is driven by the ON operation of the operation switch 10 and the suction fan 8 rotates, the outside air is sucked into the tank 2 through a hose or the like connected to the suction port 11 and passes through the suction port 9. 8 is sent to the air supply path 14 in the cowling 6 and discharged from the exhaust port 15 on the lower surface of the cowling 6. Here, when water is sucked into the tank 2, the float 13 rises as the water level stored in the tank 2 rises, and the suction port 9 is closed at the upper limit position to stop sucking water. Reference numeral 16 denotes a cloth filter which is sandwiched between the tank cover 5 and the opening of the tank 2 and blocks between the suction port 11 and the suction unit 4 in a bag shape. Air or water sucked from the suction port 11 Can be filtered here (Patent Document 1 as an example of a dust collector having a float).

特公昭６１−５７７６３号公報Japanese Patent Publication No. 61-57663

上記従来の集塵機１においては、吸気ユニット４の吸気口９が真下に向かって開口しているため、集塵の際にはフロート１３を吸い上げようとする上向きの力が常に働くことになる。従って、水等を吸引する際、水位の上昇に連れて上昇したフロート１３が吸気口９に近づくと、フロート１３が上限位置に到達する前に吸い上げられて吸気口９を閉塞してしまい、タンク２の設定容量分だけ吸引できないことがあった。かといって、吸い上げに負けない重量や大きさを有するフロートを用いると、フロートの大型化や集塵機自体の重量化に繋がってしまう。   In the conventional dust collector 1, since the intake port 9 of the intake unit 4 is opened directly below, an upward force for sucking up the float 13 always acts during dust collection. Accordingly, when the float 13 that has risen as the water level rises approaches the intake port 9 when water or the like is sucked, the float 13 is sucked up before reaching the upper limit position, and the intake port 9 is blocked. In some cases, suction could not be performed by the set volume of 2. On the other hand, if a float having a weight and a size that cannot be defeated by sucking is used, the float becomes larger and the dust collector itself becomes heavier.

そこで、本発明は、フロートの大型化や集塵機の重量化を招くことなく、フロートの不安定な動作を解消し、タンクの設定容量まで水等の確実な吸引を可能とする集塵機を提供することを目的としたものである。   Accordingly, the present invention provides a dust collector that eliminates unstable operation of the float and enables reliable suction of water or the like up to the set capacity of the tank without causing an increase in the size of the float or an increase in the weight of the dust collector. It is aimed at.

上記目的を達成するために、請求項１に記載の発明は、吸気口を、吸気ユニットから下方へ突出させて横向きに開口形成する一方、フロートの上部に、上限位置で吸気口を閉塞する閉塞部を形成したことを特徴とするものである。
請求項２に記載の発明は、請求項１の構成において、閉塞部を簡単に形成するために、フロートを、上限位置で吸気口を上部に収容して吸気ユニットの下面に当接する筒状体として、フロートの内部に、上限位置で吸気口の下面に当接してフロート内を仕切る受け壁を設けて、受け壁の上方を閉塞部としたことを特徴とするものである。
請求項３に記載の発明は、請求項２の構成において、受け壁における吸気口の下面との当接位置よりもフロートの中心側に、受け壁を貫通する排出口を形成したことを特徴とするものである。 In order to achieve the above object, according to the first aspect of the present invention, the air intake port projects downward from the air intake unit to form a lateral opening, while the air intake port is blocked at the upper limit position at the upper limit position. The portion is formed.
According to a second aspect of the present invention, in the configuration of the first aspect, in order to easily form the blocking portion, the float is a cylindrical body that accommodates the intake port at the upper limit position and abuts the lower surface of the intake unit. As described above, a receiving wall that abuts the lower surface of the intake port at the upper limit position to partition the inside of the float is provided inside the float, and the upper portion of the receiving wall is a closed portion.
The invention according to claim 3 is characterized in that, in the configuration of claim 2, a discharge port penetrating the receiving wall is formed closer to the center side of the float than a contact position of the receiving wall with the lower surface of the intake port. To do.

請求項１に記載の発明によれば、吸気口を横向きにしてフロートを吸い上げる力が働かないようにしたので、フロートが上限位置に到達する前に吸気口を閉塞することがなく、タンク内に設定容量まで確実に水等の吸引が可能となる。而も、フロートに閉塞部を形成する簡単な形状変更で不安定な動作を解消できるため、フロートの大型化や集塵機の重量化を招くこともない。
請求項２に記載の発明によれば、請求項１の効果に加えて、筒状体のフロートを合理的に利用して閉塞部を簡単に形成することができる。
請求項３に記載の発明によれば、請求項２の効果に加えて、受け壁への排出口の採用により、閉塞部内に水等が溜まるおそれがなくなり、フロートの上限位置での閉塞部のシール性も好適に維持される。
According to the first aspect of the present invention, the suction port is turned sideways so that the force for sucking up the float does not work, so that the suction port is not blocked before the float reaches the upper limit position, Water can be reliably sucked up to the set capacity. However, an unstable operation can be eliminated by a simple shape change that forms a closed portion in the float, so that the size of the float and the weight of the dust collector are not increased.
According to invention of Claim 2, in addition to the effect of Claim 1, the obstruction | occlusion part can be easily formed using the float of a cylindrical body rationally.
According to the third aspect of the present invention, in addition to the effect of the second aspect, by adopting the discharge port to the receiving wall, there is no possibility that water or the like accumulates in the closed portion, and the closed portion at the upper limit position of the float is eliminated. Sealability is also suitably maintained.

以下、本発明の実施の形態を図面に基づいて説明する。
図１は、集塵機の一例を示す縦断面図であるが、ここに示す集塵機も、タンクや本体等の基本的な機構は図３で示した従来の集塵機と同様であるので、同じ構成部には同じ符号を付して重複する説明は省略し、異なる構成部を主に説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a longitudinal sectional view showing an example of a dust collector. The basic mechanism of the dust collector shown here is the same as that of the conventional dust collector shown in FIG. Are denoted by the same reference numerals and redundant description is omitted, and different components will be mainly described.

この集塵機１では、吸気ユニット４の下面に形成される吸気口２０が、下向きに開口せず、吸気ユニット４のハウジングとなる有底筒状のタンクカバー５の下面よりも下方へ突出して横向きに開口している点がまず異なる。具体的には、平面視円形で円錐状の下板２１を仕切板２２を介してタンクカバー５に連結することで、横向きの吸気口２０が下方へ突設される。これにより、吸込口１１からタンク２内に吸い込まれる空気は、矢印で示すように、タンク２の中心に位置する吸気口２０に向けて水平に若しくはやや下方から吸気口２０に吸い込まれることになる。   In this dust collector 1, the intake port 20 formed on the lower surface of the intake unit 4 does not open downward, and protrudes downward from the lower surface of the bottomed cylindrical tank cover 5 serving as a housing of the intake unit 4 so as to face sideways. The first difference is the opening. Specifically, by connecting a conical lower plate 21 having a circular shape in plan view to the tank cover 5 via a partition plate 22, the lateral intake port 20 protrudes downward. Thereby, the air sucked into the tank 2 from the suction port 11 is sucked into the suction port 20 horizontally or slightly from below toward the suction port 20 located at the center of the tank 2 as indicated by an arrow. .

また、フロートケージ１３内のフロート２３も、ここでは上限位置でタンクカバー５の下面に当接して吸気口２０を上部に収容する筒状体となっており、その内部に、上限位置で下板２１の下面に当接してフロート２３内を仕切る受け壁２４を設けている。一方、タンクカバー５におけるフロート２３との当接位置と、受け壁２４における下板２１との当接位置とには、当接する部材間をシールするリング状のシール部材２５，２６が夫々貼着されている。これにより、フロート２３内で受け壁２４の上部には、上限位置で吸気口２０がシール状態で完全収容される閉塞部２７が形成されることになる。   In addition, the float 23 in the float cage 13 is also a cylindrical body that comes into contact with the lower surface of the tank cover 5 at the upper limit position and accommodates the intake port 20 in the upper portion. A receiving wall 24 is provided in contact with the lower surface of 21 to partition the inside of the float 23. On the other hand, ring-shaped seal members 25 and 26 for sealing between the abutting members are attached to the abutting position of the tank cover 5 with the float 23 and the abutting position of the receiving wall 24 with the lower plate 21, respectively. Has been. As a result, an upper portion of the receiving wall 24 in the float 23 is formed with a closing portion 27 in which the intake port 20 is completely accommodated in a sealed state at the upper limit position.

さらに、受け壁２４における下板２１との当接位置よりもフロート２３の中心側は、中心へ向けて緩やかに下り傾斜するすり鉢状に形成されて、受け壁２４の中心には、下方へ向かって垂下し、受け壁２４を貫通して閉塞部２７を下方へ連通させる筒状の排出口２８が形成されている。   Furthermore, the center side of the float 23 is formed in a mortar shape that gently descends and inclines toward the center from the position where the receiving wall 24 contacts the lower plate 21, and the center of the receiving wall 24 faces downward. A cylindrical discharge port 28 is formed which hangs down and penetrates the receiving wall 24 and allows the closing portion 27 to communicate downward.

以上の如く構成された集塵機１においては、カウリング６の側面に設けた運転スイッチ１０をＯＮ操作してモータ７を駆動させると、吸込ファン８が回転し、吸込口１１から空気が吸い込まれる。タンク２内に吸込まれた空気は、フィルタ１６を通って横向きの吸気口２０に入り、吸込ファン８によりカウリング６内の送気路１４へ送られて、排気口１５から排出される。この空気の流れにより、吸込口１１から吸込まれる空気がフィルタ１６で濾過され、塵埃等がタンク２内に貯留される。
一方、吸込口１１に接続した図示しないホースによって例えば水を吸い込んだ場合、タンク２内に水が貯留されることになるが、水位が上昇すると、フロートケージ１２内のフロート２３もそれに応じて上昇する。このとき、吸気口２０では空気が横向きに吸い込まれるため、フロート２３に吸い上げる力が働くことがない。 In the dust collector 1 configured as described above, when the operation switch 10 provided on the side surface of the cowling 6 is turned on to drive the motor 7, the suction fan 8 rotates and air is sucked from the suction port 11. The air sucked into the tank 2 passes through the filter 16 and enters the lateral intake port 20, is sent to the air supply path 14 in the cowling 6 by the suction fan 8, and is discharged from the exhaust port 15. Due to this air flow, air sucked from the suction port 11 is filtered by the filter 16, and dust and the like are stored in the tank 2.
On the other hand, when water is sucked in by a hose (not shown) connected to the suction port 11, for example, water is stored in the tank 2, but when the water level rises, the float 23 in the float cage 12 rises accordingly. To do. At this time, air is sucked sideways at the air inlet 20, so that the suction force does not act on the float 23.

そして、フロート２３が上限位置に到達すると、前述のようにフロート２３の上端がタンクカバー５の下面に当接すると共に、受け壁２４が下板２１の下面に当接して、吸気口２０がフロート２３の閉塞部２７内に完全収容される。この状態で、フロート２３の上端とタンクカバー５の下面との間がシール部材２５により、受け壁２４の上面と下板２１の下面との間がシール部材２６により夫々シールされるため、吸気口２０が密閉されて吸気ユニット４への空気の流入が停止する。よって、それ以上の水の吸引が阻止される。   When the float 23 reaches the upper limit position, the upper end of the float 23 comes into contact with the lower surface of the tank cover 5 as described above, the receiving wall 24 comes into contact with the lower surface of the lower plate 21, and the intake port 20 moves to the float 23. Is completely accommodated in the closed portion 27. In this state, the space between the upper end of the float 23 and the lower surface of the tank cover 5 is sealed by the seal member 25, and the space between the upper surface of the receiving wall 24 and the lower surface of the lower plate 21 is sealed by the seal member 26. 20 is sealed and the inflow of air into the intake unit 4 is stopped. Therefore, further suction of water is prevented.

なお、水の吸引の際に、タンク２内での飛散や吸気口２０からの落下等によってフロート２３の閉塞部２７内に水が進入することがあっても、そのまま受け壁２４の傾斜によって中央の排出口２８へ誘導されてタンク２内へ戻される。よって、フロート２３の上限位置での閉塞部２７のシール性を低下させたり、吸気口２０に水が進入したりするおそれがない。   Even when water enters the closed portion 27 of the float 23 due to scattering in the tank 2 or dropping from the intake port 20 when water is sucked, the center of the water is not affected by the inclination of the receiving wall 24. To the discharge port 28 and returned to the tank 2. Therefore, there is no possibility that the sealing performance of the blocking portion 27 at the upper limit position of the float 23 is deteriorated or that water enters the air inlet 20.

このように、上記形態の集塵機１によれば、吸気口２０を、吸気ユニット４から下方へ突出させて横向きに開口形成する一方、フロート２３の上部に、上限位置で吸気口２０を閉塞する閉塞部２７を形成したことで、フロート２３が上限位置に到達する前に吸気口２０を閉塞することがなく、タンク２内に設定容量まで確実に水の吸引が可能となる。而も、フロート２３に閉塞部２７を形成する簡単な形状変更で不安定な動作を解消できるため、フロート２３の大型化や集塵機１自体の重量化を招くこともない。   As described above, according to the dust collector 1 of the above-described form, the intake port 20 protrudes downward from the intake unit 4 so as to be opened sideways, while the intake port 20 is blocked at the upper limit of the float 23 at the upper limit position. By forming the portion 27, the intake port 20 is not blocked before the float 23 reaches the upper limit position, and water can be reliably sucked up to the set capacity in the tank 2. In addition, since an unstable operation can be eliminated by a simple shape change in which the closed portion 27 is formed in the float 23, the size of the float 23 and the weight of the dust collector 1 itself are not increased.

特にここでは、フロート２３を、上限位置で吸気口２０を上部に収容して吸気ユニット４の下面に当接する筒状体として、フロート２３の内部に、上限位置で下板２１の下面に当接してフロート２３内を仕切る受け壁２４を設けて、受け壁２４の上方を閉塞部２７としたことで、筒状体のフロート２３を合理的に利用して閉塞部２７を簡単に形成することができる。
また、受け壁２４における下板２１の下面との当接位置よりもフロート２３の中心側に、受け壁２４を貫通する排出口２８を形成したことで、閉塞部２７内に水や塵埃が溜まるおそれがなくなり、フロート２３の上限位置での閉塞部２７のシール性も好適に維持される。 In particular, here, the float 23 is a cylindrical body that accommodates the intake port 20 in the upper position at the upper limit position and contacts the lower surface of the intake unit 4, and contacts the lower surface of the lower plate 21 at the upper limit position. By providing the receiving wall 24 for partitioning the inside of the float 23 and forming the closed portion 27 above the receiving wall 24, the closed portion 27 can be easily formed by rationally using the float 23 of the cylindrical body. it can.
Further, since the discharge port 28 penetrating the receiving wall 24 is formed on the center side of the float 23 with respect to the contact position of the receiving wall 24 with the lower surface of the lower plate 21, water and dust accumulate in the closed portion 27. There is no fear, and the sealing performance of the closing portion 27 at the upper limit position of the float 23 is also suitably maintained.

なお、上記形態では、タンクカバーの下面とフロートとの間のシール部材をタンクカバー側に、吸気口の下面とフロートの受け壁との間のシール部材を受け壁側に設けているが、夫々逆側に設けるようにしてもよい。また、シール部材は必ずしも必要ではなく、例えばタンクカバーの下面に、上限位置でフロート部の上端が嵌合するリング溝を凹設する等してシール性が確保できれば、シール部材は省略して差し支えない。
また、吸気口も、横向きに開口形成されるものであれば数や具体的な形態は適宜変更可能で、フロートの閉塞部も、吸気口の形状によってはフロートの上端へ壁体を部分的に立設して吸気口を閉塞するようにしてもよい。
さらに、排出口も、複数設けてよいし、筒状体に限らず単純な透孔としてもよい。勿論省略することも可能である。 In the above embodiment, the seal member between the lower surface of the tank cover and the float is provided on the tank cover side, and the seal member between the lower surface of the intake port and the float receiving wall is provided on the receiving wall side. It may be provided on the opposite side. Further, the seal member is not necessarily required. For example, if the seal performance can be secured by forming a ring groove into which the upper end of the float portion is fitted at the upper limit position on the lower surface of the tank cover, the seal member may be omitted. Absent.
In addition, the number and specific form of the intake port can be appropriately changed as long as the intake port is formed sideways, and the closed portion of the float may also partially extend the wall body to the upper end of the float depending on the shape of the intake port. The intake port may be closed by standing.
Furthermore, a plurality of outlets may be provided, and the outlet is not limited to a cylindrical body and may be a simple through hole. Of course, it can be omitted.
