る。BACKGROUND ART The general structure of a drainage pump for discharging condensate etc. generated from air conditioning equipment, etc. has conventionally been as shown in FIG. 5. That is, a runner 5 having a substantially inverted triangular shape, which is directly connected by a shaft 6 coaxially with the drive shaft 12 of the motor 11 and has a plurality of blades with the axis perpendicular to the drive shaft 12, has a suction port 2 that opens at an end surface 9 at the lower end. It is rotatably housed in a substantially hollow inverted conical main body 1 having a discharge port 3 on the upper outer periphery with an appropriate distance 8. Although not shown, a lid 7 is fitted onto the upper end of the main body 1 by a method such as tightening a screw with a hinge.
The motor 11 is attached and fixed to the lid 7 with a butterfly.

である。 When the motor 11 is energized, the runner 5, which is linked to its rotation, sucks in condensate from the suction port 2, and the condensate that moves upward, where the circumferential speed of the runner 5 having inverted triangular blades is high, is drawn into the upper part of the runner 5. It is then pushed out to the side and is discharged from the discharge port 3 which is open at the upper outer circumference of the main body 1.

吸入側に設ける等の手段を講じている。 Drain generated from air conditioners, especially those that have recently become popular, including ceiling-mounted and other commercial air conditioners, contains a large amount of dust such as fibrous garbage, earth and sand, and wood chips. Ordinary mesh filters quickly become clogged and prevent drain from passing through to the suction port 2, so mesh filters are generally not used. Measures are taken such as installing a strainer on the suction side of the pump.
また、繊維状の長いゴミがポンプ内に流入した
ときには、これを容易に通過させる様にランナに
切欠きを設けた特開昭61−104191号公報に開示さ
れた従来技術がある。 Furthermore, there is a conventional technique disclosed in Japanese Patent Application Laid-Open No. 104191/1983 in which a cutout is provided in the runner so that when long fibrous dirt flows into the pump, it can easily pass through.

In addition, there are fragments of thin chemical fiber fabrics, pieces of paper, and especially so-called plastic bags such as low-density polyethylene (LDPE) plastics, which are floating in the drain.
It passes through the grid-like strainer of the prior art in the deflated state, and is then redeployed to cover or adhere to the end face 9 of the pump inlet 2 in a cap shape to block the inlet 2 and drain. Accidents that made pumping impossible often occurred.

ことである。Problems to be Solved by the Invention The present invention solves the problem that the above-mentioned thin film-like pieces of plastic and other materials floating in the drain, which could not be prevented by the above-mentioned conventionally known techniques, can cause the inlet end face of the pump to To obtain a drainage pump which prevents the drain from being blocked and unable to pump up the drain, thereby impairing its discharge function.
問題を解決するための手段
上記問題を解決する手段は、以下説明する本考
案の構成によるものである。Means for Solving the Problem The means for solving the above problem is based on the configuration of the present invention described below.

的を達成することが可能となるものである。 In other words, it is coaxial with the drive shaft of the motor, and is rotatably housed in a substantially hollow inverted conical body with an inlet at the lower end and an outlet at the upper outer periphery. A drainage pump is provided with a plurality of notched grooves in the lower end surface of the suction port of the pump, which has a substantially inverted triangular runner formed with a plurality of blades with the axis perpendicular to the drain pump. It is possible to achieve the purpose.

中を通過し排出口から排出処理される。Effects With the above structure of the present invention, the runner also rotates at the same time as the motor operates, and the drain pumped in from the suction port at the bottom of the main body is drained from the discharge port. Even if the thin film-like fragments floating in the drain that has passed through the grid-like strainer in a shrunken state are redeployed and expanded and cover the suction port, a plurality of cuts are made on the end face of the suction port. Since the grooves are provided, drain can pass through the grooves and can be pumped up without interfering with the pumping action. There is no fear that the thin film-like piece will stick to the end face of the suction port, and is squeezed by the suction action of the pump, becomes deflated, passes through the pump, and is discharged from the discharge port.

ある。Effects As detailed above, the drainage pump according to the present invention has a plurality of notched grooves on the suction end face at the lower end of the pump body, so that the drainage pump contained in the drain in the drain tank and suspended in the drain tank can be removed. Even if the thin film-like section covers the end face of the suction port in a cap-like manner, the drain can be pumped up by allowing the drain to pass between the sections, so that the pumping action is not hindered. There is no fear that the thin film-like piece will stick to the end face of the suction port, and therefore the suction port can be prevented from being blocked. Furthermore, the thin film-like section is squeezed out of the suction port by the suction action of the pump, becomes atrophied, passes through the pump as it is, and is drained from the discharge port, and the pump drains the suction port without blocking it. This has the effect of making it possible to operate the suction and discharge functions without any hindrance.
