【産業上の利用分野】[Industrial applications]

本考案は排水ポンプに関し、特に空調機器などから発生するドレンを連続的に 排出するに適するポンプに関する。 The present invention relates to a drainage pump, and more particularly to a pump suitable for continuously discharging drainage generated from air conditioners and the like.

【0002】[0002]

【従来の技術】[Prior Art]

空調機器などから発生するドレンは、必ずしも定常的には発生せず、しかもご みなどを含有している。このようなドレンを排出するための排水管を建物等の構 造上あるいは美観上で不都合のない場所に設けようとすると、排水管の勾配が取 れないなどのためにごみ詰りなどを生じ易く、故障の原因となっていた。 Drain generated from air conditioners does not always occur steadily, and it also contains dust. If it is attempted to provide a drainage pipe for draining such a drain in a place where there is no inconvenience in terms of structure or aesthetics of the building, etc., the drainage pipe will not be steep, and dust will be prone to clogging. , Was causing a failure.

【0003】 そこで、ドレンを排水ポンプによって強制的に排水することが提案された。か かるポンプ排水方式では、ドレンが一定量溜るとポンプを運転して排水する方法 もあるが、ドレンが貯留する容器を設けると共にドレン貯留レベルを検出してポ ンプの電源を開閉するスイッチを設けなければならず、大型となるうえ経済的で ない。Therefore, it has been proposed to forcibly drain the drain with a drain pump. There is also a method of draining the pump by operating the pump when a certain amount of drain is accumulated in the drainage system, but a container for storing the drain is provided and a switch for detecting the drain storage level and opening / closing the power source of the pump is provided. It has to be large, and it is large and not economical.

【0004】 一方、ポンプを常時運転しておき、ドレンが流入するに応じてそのたびに排出 する方法があり、ごみ等を含有していて流量変動が多いドレンを排出する適した 小型の排水ポンプが提案されている(実開昭59−154897、特開昭61− 104191など)。ところが、このような小型の排水ポンプは、ドレンが流入 して排水が始まるたびに大きな騒音を発する欠点を有している。On the other hand, there is a method of constantly operating the pump and discharging the drain whenever it flows in. A compact drainage pump suitable for discharging the drain that contains dust and the like and whose flow rate varies a lot. Have been proposed (Japanese Utility Model Laid-Open No. 59-154897, Japanese Patent Laid-Open No. 61-104191, etc.). However, such a small-sized drainage pump has a drawback that a large amount of noise is generated every time drainage flows in and drainage starts.

【考案が解決しようとする課題】[Problems to be solved by the device]

上述のような事情の下で、本考案は、常時連続運転をしながら流入水量の大幅 な変動に対応できる排水能力を有し、ごみ詰りを起さないばかりでなく、特に排 水騒音の低い小型排水ポンプを提供しようとするものである。 Under the circumstances as described above, the present invention has a drainage capacity capable of responding to a large fluctuation of the inflow water amount while continuously operating continuously, and not only does not cause dust clogging but also particularly low drainage noise. It aims to provide a small drainage pump.

【課題を解決するための手段】[Means for Solving the Problems]

前記の如き本考案の目的は、軸線に直交する円盤部の下面側に平板状羽根を軸 線を含んで垂設してなり、該円盤部の該平板状羽根で分割された半円部分の夫々 に、該円盤部の上下両側を連絡するスリットを軸近傍から外周縁まで軸対称に設 けるとともに該スリットの後縁下側を斜めに削り落としてあることを特徴とする 排水ポンプ用ランナを、軸線を垂直として上面に通気路を設けた略逆円錐形状の ポンプケースを有する排水ポンプ内に垂設することによって達成される。 As described above, the object of the present invention is such that a flat blade including the axis is vertically provided on the lower surface side of the disk portion orthogonal to the axis, and the semicircular portion of the disk portion divided by the flat blade is formed. Each of the drainage pump runners is characterized in that a slit connecting the upper and lower sides of the disk portion is provided axially symmetrically from the vicinity of the axis to the outer peripheral edge, and the lower side of the trailing edge of the slit is cut off obliquely. It is achieved by vertically arranging it in a drainage pump having a substantially conical pump case with a ventilation path provided on the upper surface with the axis being vertical.

【0007】 本考案のポンプ用ランナの平板状羽根の形状は、ポンプケースの形状に合わせ て略三角形であるのが好ましく、羽根の縁とポンプケースの内面との間は、ごみ 詰まりが起らぬよう適宜の間隙が維持されていることが好ましい。The flat blades of the pump runner according to the present invention preferably have a substantially triangular shape according to the shape of the pump case, and dust clogging occurs between the edges of the blades and the inner surface of the pump case. It is preferable that an appropriate gap be maintained so as to prevent

【0008】 また、ランナの円盤部に対称的に設けられるスリットは、円盤部の上側と下側 との圧力を均等化するためのもので、また軸付近のごみなどを外周縁に押出す機 能をも有している。従ってスリットの形状としては外周に向って放射状に設けら れていてもよいが、ランナの回転方向に対して外側ほど後退するような形態に設 けられるのがより好ましい。The slits provided symmetrically on the disk portion of the runner are for equalizing the pressure on the upper side and the lower side of the disk portion, and a machine for pushing out dust around the shaft to the outer peripheral edge. It also has the ability. Therefore, the shape of the slit may be radially provided toward the outer circumference, but it is more preferable that the slit is formed so as to recede toward the outer side with respect to the rotation direction of the runner.

【実施例】【Example】

本考案の排水ポンプの実施例を第1〜2図によって説明する。 1はポンプケースであり、内面は略円錐形状に形成され、軸線が垂直となるよ うに設けられている。その下端は絞られた吸入口1aを形成しており、上部側方 に排出口1bが設けられている。2はランナであり、その軸2aがモータ4の回 転軸4aに嵌着されている。 An embodiment of the drainage pump of the present invention will be described with reference to FIGS. Reference numeral 1 denotes a pump case, the inner surface of which is formed in a substantially conical shape, and the axis of which is vertical. A lower end thereof forms a narrowed intake port 1a, and a discharge port 1b is provided on the upper side. Reference numeral 2 is a runner, the shaft 2a of which is fitted to the rotating shaft 4a of the motor 4.

【0011】 3は蓋であり、ポンプケース1の上面開口部にねじ6などによって取り付けら れるとともに、その上方にはモータ4が固定されるようになっている。蓋3には 、軸2aが緩く貫通できる孔3aが設けられ、空気を自由に吸入できるようにな っている。また、5は水切板である。Reference numeral 3 denotes a lid, which is attached to the opening of the upper surface of the pump case 1 by a screw 6 or the like, and the motor 4 is fixed above it. The lid 3 is provided with a hole 3a through which the shaft 2a can be loosely penetrated, so that air can be freely sucked. Further, 5 is a draining plate.

【0012】 ランナ2には、軸2aに垂直に円盤部2bが設けられ、更に円盤部2bの下方 には平板状の羽根2cが軸線を含むように設けられている。羽根2cは下端が細 く略三角形状となっており、円盤部2bを2つの半円部に分割している。これら の半円部のそれぞれには、スリット2dが相互に対称的に設けられ、これによっ て円盤部2bの上側と下側とが連絡されている。このスリット2dの形状は、ラ ンナ2を下側からみて(第2図(c) )、ランナ2が時計方向に回転するように設 定されているときは、軸近傍の透孔部2eから外周縁まで次第に反時計方向に後 退するように形成してある。The runner 2 is provided with a disc portion 2b perpendicular to the shaft 2a, and further, a flat blade 2c is provided below the disc portion 2b so as to include the axis. The blade 2c has a thin, generally triangular shape at the lower end, and divides the disc portion 2b into two semicircular portions. Slits 2d are provided symmetrically to each other in each of these semicircular portions, so that the upper side and the lower side of the disc portion 2b are connected to each other. When the runner 2 is set to rotate clockwise when the runner 2 is viewed from the lower side (see FIG. 2 (c)), the shape of the slit 2d is from the through hole portion 2e near the axis. It is formed so that it gradually recedes counterclockwise to the outer peripheral edge.

【0013】 このような形状のランナを備えた本考案の排水ポンプを、その吸入口1aがド レン受皿内に位置するように据付け、ランナ2を回転しながらドレン受皿内に徐 々に給水してゆく。回転している羽根2cの先端部分に水が接触すると、水に遠 心力が働くようになる。そしてポンプケース1内の水位が高まると、水が遠心力 により排出口1bに送出されると同時に、ポンプケース1内の空気も水に伴って 排出される。ポンプケース1内には孔3aを経て空気が流入し、透孔部2eを含 むスリット2dを通じてランナ2の円盤部2bの上下両側で釣合った空気の流れ が生じており、供給された水は、その流量にかかわらず円滑に排出され、大きな 騒音は発生しない。The drainage pump of the present invention provided with the runner having such a shape is installed so that its suction port 1a is located in the drain pan, and while the runner 2 is rotated, water is gradually supplied into the drain pan. Go on. When water comes into contact with the tip of the rotating blade 2c, centrifugal force acts on the water. When the water level in the pump case 1 rises, the water is sent to the discharge port 1b by centrifugal force, and at the same time, the air in the pump case 1 is also discharged along with the water. Air flows into the pump case 1 through the hole 3a, and a balanced air flow is generated on the upper and lower sides of the disk portion 2b of the runner 2 through the slit 2d including the through hole portion 2e. Is discharged smoothly regardless of its flow rate, and no loud noise is generated.

【0014】 以下に、本考案の排水ポンプの排水騒音の測定結果の例を示す。 円盤部の直径31mmのランナを備えた第1図の排水ポンプAを、ドレン受皿の 底面と吸入口との距離が5mmとなるように据付け、一方排出口に接続した排水管 を揚程500mmとなるように設置した。ポンプを運転しながらドレン受皿に対し て供給する水量を変化させ、ポンプの直上1mの位置における騒音レベルを測定 した。その結果を、第6図中にグラフ(A)として示す。The following is an example of measurement results of drainage noise of the drainage pump of the present invention.

While the pump was operating, the amount of water supplied to the drain pan was changed and the noise level was measured 1 m directly above the pump. The result is shown as a graph (A) in FIG.

【0015】 また、ランナを第3図に示したような、円盤部を有しない三角板状羽根型のも の(実開昭59−154897に開示されたものと同形状、最大幅は31mm)B に交換して、前記と同様な測定を行なった結果を、同様に第6図のグラフ(B) に示した。更に、ランナを第4図に示した形状のものとし、ポンプケースを第5 図に示した形状のものを用てい組立てた排水ポンプC(特開昭61−10419 1に開示されたものと同形状、ランナの円盤部の直径31mm)についても同様な 測定を行った。その結果を第6図にグラフ(C)として示した。Further, the runner is of a triangular plate blade type having no disk portion as shown in FIG. 3 (the same shape as that disclosed in Japanese Utility Model Laid-Open No. 59-154897, the maximum width is 31 mm) B The result of the same measurement as above was shown in the graph (B) of FIG. Further, a drainage pump C having the shape shown in FIG. 4 and the pump case having the shape shown in FIG. 5 is assembled (same as the one disclosed in JP-A-61-1104191). The same measurement was performed for the shape and the diameter of the disk portion of the runner 31 mm). The result is shown as a graph (C) in FIG.

【0016】 これらの結果をみると、本考案の排水ポンプは,騒音レベルにおいて著しく改 良されていることがわかる。From these results, it can be seen that the drainage pump of the present invention is remarkably improved in noise level.
