Description

本発明は、空調機に装備される排水ポンプに関する。   The present invention relates to a drainage pump installed in an air conditioner.

空調機の室内ユニットは、冷房運転時に熱交換器に空気中の水分が凝縮して付着し、これがドレン水として熱交換器の下方に設けられるドレンパン内に滴下する。このドレンパン内に溜ったドレン水を排水するために排水ポンプが用いられる。この排水ポンプは、下部に吸込口を形成し、上部を開口すると共に、側方に吐出口を設けたポンプ本体ケースを含むハウジング内に回転羽根を回転自在に設け、この回転羽根をハウジングの開口の上部にカバーを介して固定したモータにより回転させている。そのモータの駆動軸は、カバーに形成された貫通穴を回転自在に貫通して羽根のシャフト部に連結され、モータを駆動して回転羽根が回転すると、ドレンパン内に貯溜したドレン水は、吸込口の下端から吸込まれ、遠心力により揚水され、吐出口から外部に吐出される。   In the indoor unit of the air conditioner, moisture in the air condenses and adheres to the heat exchanger during cooling operation, and this drops as drain water into a drain pan provided below the heat exchanger. A drainage pump is used to drain the drain water accumulated in the drain pan. This drainage pump has a suction port formed in the lower part, an upper part opened, and a rotary blade provided rotatably in a housing including a pump body case provided with a discharge port on the side. It is rotated by a motor fixed through a cover on the top. The motor drive shaft is rotatably connected to the blade shaft through a through hole formed in the cover. When the motor is driven and the rotary blade rotates, the drain water stored in the drain pan is sucked in. It is sucked in from the lower end of the mouth, pumped up by centrifugal force, and discharged to the outside from the discharge port.

図５は、従来の排水ポンプの説明図である。全体を符号１で示す排水ポンプは、電動モータ１０を有し、電動モータ１０は、リード線１１を介して給電される。電動モータ１０は、ブラケット２０により支持され、ブラケット２０の下端部は、ケース本体５０の上部に取付けられる蓋部材３０に連結される。ケース本体５０と蓋部材３０とによって排水ポンプのハウジングが構成される。   FIG. 5 is an explanatory diagram of a conventional drainage pump. The drainage pump generally indicated by reference numeral 1 has an electric motor 10, and the electric motor 10 is supplied with power via a lead wire 11. The electric motor 10 is supported by the bracket 20, and the lower end portion of the bracket 20 is connected to a lid member 30 attached to the upper portion of the case body 50. The case main body 50 and the lid member 30 constitute a drain pump housing.

ケース本体５０は、プラスチックでつくられ、内部にポンプ室５２が形成される。ケース本体５０には、ポンプ室５２に連通される吸込口６０と吐出口７０が一体に形成される。
ポンプ室５２内には、回転羽根１００が配設され、ポンプ室５２の開口部は蓋部材３０で覆われる。ケース本体５０と蓋部材３０の間にはシール部材４０が挿入され、ポンプ室からのドレン水の漏水が防止される。回転羽根１００は軸部１１０を有し、軸部１１０の有底穴に電動モータ１０の出力軸１２が挿入される。軸部１１０から放射方向に延びる板状の大径羽根１２０を有し、大径羽根１２０は、連結部１３０を介して小径羽根１４０に接続される。吸込口からのドレン水が小径羽根１４０、連結部１３０を介して大径羽根１２０側へ送られる。 The case body 50 is made of plastic, and a pump chamber 52 is formed therein. The case body 50 is integrally formed with a suction port 60 and a discharge port 70 that communicate with the pump chamber 52.
The rotary vane 100 is disposed in the pump chamber 52, and the opening of the pump chamber 52 is covered with the lid member 30. A seal member 40 is inserted between the case main body 50 and the lid member 30 to prevent drain water from leaking from the pump chamber. The rotary blade 100 has a shaft portion 110, and the output shaft 12 of the electric motor 10 is inserted into a bottomed hole of the shaft portion 110. A plate-shaped large-diameter blade 120 extending in the radial direction from the shaft portion 110 is provided, and the large-diameter blade 120 is connected to the small-diameter blade 140 via the connecting portion 130. Drain water from the suction port is sent to the large-diameter blade 120 side through the small-diameter blade 140 and the connecting portion 130.

水切り板１４は、板状で円形であり中央部に孔を有し、出力軸１２に圧入されている。水切り板１４により蓋部材３０の貫通穴３６から噴出するドレン水（特に戻り水）がモータ１０側へ飛散するのを防止する。
特開平９−５３５９１号公報 The draining plate 14 is plate-shaped and circular, has a hole in the center, and is press-fitted into the output shaft 12. Drain water (especially return water) ejected from the through hole 36 of the lid member 30 by the draining plate 14 is prevented from splashing to the motor 10 side.
Japanese Patent Laid-Open No. 9-53591

しかし、図５の構成では、水切り板１４は、出力軸１２に圧入されているだけであるので、図６に示すように水切り板１４と軸部１１０の端部１１１との間には隙間ができ、水が金属の出力軸１２に触れてしまう。このように飛散水が排水ポンプの帯電した出力軸１２に触れることは、漏電の可能性や電動モータ１０の作動不良の原因になるなど、好ましいことではない。なお、基礎絶縁の破壊によって帯電し得る出力軸１２は安全規格状において充電部として取り扱われ、ＩＥＣ６０３３５−１やＪＩＳ Ｃ ９３３５−１には「通常の使用で接触可能となっている又は可能性のある導電性液体は充電部と直接接触してはならない」と規定されており、この規格に適合するように対策を施す必要がある。   However, in the configuration of FIG. 5, the draining plate 14 is only press-fitted into the output shaft 12, so that there is a gap between the draining plate 14 and the end portion 111 of the shaft portion 110 as shown in FIG. 6. The water touches the metal output shaft 12. It is not preferable that the splashed water touches the charged output shaft 12 of the drainage pump in this manner because it may cause electric leakage or cause malfunction of the electric motor 10. In addition, the output shaft 12 that can be charged by the breakdown of the basic insulation is handled as a charging part in the safety standard, and IEC 60335-1 and JIS C 9335-1 “can be contacted or possibly used in normal use” Certain conductive liquids must not come into direct contact with live parts ”, and measures must be taken to comply with this standard.

本発明は、上記課題に鑑みて、空調機に装備される排水ポンプにおいて、電動モータの金属製出力軸に水が直接触れないようにして安全性を高めた排水ポンプを提供することを目的とする。   In view of the above problems, an object of the present invention is to provide a drainage pump that is improved in safety by preventing water from directly touching a metal output shaft of an electric motor in a drainage pump installed in an air conditioner. To do.

上記目的を達成するため、本発明の排水ポンプは、ケース本体とその開口部を覆う蓋部材とで構成されるハウジングと、このハウジングの内部空間に収容される回転羽根と、この回転羽根を回転駆動するモータとを含み、前記ケース本体は、その下部にドレン水の吸込口を、その側部にドレン水の吐出口をそれぞれ備え、前記蓋部材と前記モータとの間に水切り板が配置される排水ポンプであって、前記回転羽根には、前記モータの出力軸に連結される軸部が前記蓋部材から突出するように一体に形成されており、前記水切り板は前記軸部のモータ側端部に装着されることを特徴とする。
さらに、本発明の排水ポンプは、前記水切り板は前記軸部のモータ側端部に形成された外周溝に装着され、また、前記軸部のモータ側端部には前記水切り板の装着を容易にするテーパ部が設けられることを特徴とする。 In order to achieve the above object, a drainage pump according to the present invention includes a housing composed of a case main body and a lid member covering the opening, a rotating blade accommodated in the internal space of the housing, and rotating the rotating blade. The case body includes a drain water suction port at a lower portion thereof and a drain water discharge port at a side portion thereof, and a draining plate is disposed between the lid member and the motor. The drainage pump is formed integrally with the rotary blade so that a shaft portion connected to the output shaft of the motor protrudes from the lid member, and the draining plate is on the motor side of the shaft portion. It is mounted on the end.
Further, in the drainage pump of the present invention, the draining plate is attached to an outer peripheral groove formed at the end of the shaft portion on the motor side, and the draining plate is easily attached to the end portion of the shaft portion on the motor side. A tapered portion is provided.

また、本発明の排水ポンプは、ケース本体とその開口部を覆う蓋部材とで構成されるハウジングと、このハウジングの内部空間に収容される回転羽根と、この回転羽根を回転駆動するモータとを含み、前記ケース本体は、その下部にドレン水の吸込口を、その側部にドレン水の吐出口をそれぞれ備え、前記蓋部材と前記モータとの間に水切り板が配置される排水ポンプであって、前記回転羽根には、前記モータの出力軸に連結される軸部が前記蓋部材から突出するように一体に形成され、水切り板は前記軸部のモータ側端部に一体に形成されることを特徴とする。
かかる構成を有する本発明の排水ポンプにおいては、前記蓋部材は半円状に２分割される。 Further, the drainage pump of the present invention includes a housing constituted by a case body and a lid member covering the opening, a rotary blade accommodated in the internal space of the housing, and a motor for rotationally driving the rotary blade. The case body is a drainage pump provided with a drain water suction port at a lower portion thereof and a drain water discharge port at a side portion thereof, and a draining plate disposed between the lid member and the motor. The rotating blade is integrally formed with a shaft portion connected to the output shaft of the motor so as to protrude from the lid member, and the draining plate is formed integrally with the motor side end portion of the shaft portion. It is characterized by that.
In the drainage pump of the present invention having such a configuration, the lid member is divided into two semicircles.

また、本発明の排水ポンプは、ケース本体とその開口部を覆う蓋部材とで構成されるハウジングと、このハウジングの内部空間に収容される回転羽根と、この回転羽根を回転駆動するモータとを含み、前記ケース本体は、その下部にドレン水の吸込口を、その側部にドレン水の吐出口をそれぞれ備え、前記蓋部材と前記モータとの間に水切り板が配置される排水ポンプであって、前記回転羽根には、前記モータの出力軸に連結される軸部が前記蓋部材から突出するように一体に形成されており、前記水切り板は前記モータの出力軸を貫通させて前記軸部のモータ側端部に接着剤を一周させて接着されることを特徴とする。
この場合、前記接着剤は、前記軸部のモータ側端部と前記水切り板の間の隙間を埋めるように入り込む。 Further, the drainage pump of the present invention includes a housing constituted by a case body and a lid member covering the opening, a rotary blade accommodated in the internal space of the housing, and a motor for rotationally driving the rotary blade. The case body is a drainage pump provided with a drain water suction port at a lower portion thereof and a drain water discharge port at a side portion thereof, and a draining plate disposed between the lid member and the motor. The rotating blade is integrally formed so that a shaft portion connected to the output shaft of the motor protrudes from the lid member, and the draining plate penetrates the output shaft of the motor and passes through the shaft. It is characterized in that an adhesive is circulated around the motor side end of the part.
In this case, the adhesive enters the gap between the motor side end of the shaft portion and the draining plate.

本発明の排水ポンプによれば、電動モータの金属製出力軸に水が触れることがなく、安全性が高まる。   According to the drainage pump of the present invention, water does not touch the metal output shaft of the electric motor, and safety is improved.

以下、本発明を実施するための最良の形態を説明する。   Hereinafter, the best mode for carrying out the present invention will be described.

図１は、実施例１の排水ポンプの説明図である。図２は、実施例１の排水ポンプの要部拡大図である。実施例１においては、図５、６で説明した従来の排水ポンプと同一の箇所は同一の符号を付し、図５、６で説明した従来の排水ポンプと異なる箇所について説明する。   FIG. 1 is an explanatory diagram of a drainage pump according to the first embodiment. FIG. 2 is an enlarged view of a main part of the drainage pump according to the first embodiment. In Example 1, the same code | symbol is attached | subjected to the location same as the conventional drainage pump demonstrated in FIG. 5, 6, and the location different from the conventional drainage pump demonstrated in FIG.

回転羽根２００は軸部２１０を有し、軸部２１０の有底穴２１３に電動モータ１０の金属製出力軸１２が挿入される。軸部２１０のモータ側端部にはその全周に外周溝２１２を有し、さらにその電動モータ１０側の先端はテーパ部２１１を有している。一方、非導電性の樹脂等にて形成される水切り板１５は、板状で円形であり中央部に孔を有し、この孔が軸部２１０の外周溝２１２に圧入されている。   The rotary blade 200 has a shaft portion 210, and the metal output shaft 12 of the electric motor 10 is inserted into the bottomed hole 213 of the shaft portion 210. The end of the shaft 210 on the motor side has an outer peripheral groove 212 on the entire periphery thereof, and further has a tapered portion 211 on the tip of the electric motor 10 side. On the other hand, the draining plate 15 formed of non-conductive resin or the like is plate-shaped and circular, and has a hole in the center, and this hole is press-fitted into the outer peripheral groove 212 of the shaft part 210.

次に、水切り板１５の組み付け方法について述べる。水切り板１５は、少なくとも蓋部材３０の貫通穴３６に軸部２１０を通した状態で、軸部２１０の上部から水切り板１５を圧入する。このとき、テーパ部２１１により圧入し易くなる。そして、圧入により溝部２１２に水切り板１５の中央部に有する孔が入り込み、組み付けがなされる。水切り板１５を外周溝２１２に組み付けた状態においても圧入寸法となっており、軸部２１０と水切り板１５とは確実に密着状態で装着されている。その後に、軸部２１０の有底穴２１３に電動モータ１０の出力軸１２が挿入される。ケース本体５０は、軸部２１０に出力軸１２を挿入してから組み付けても、挿入前に組み付けてもよい。   Next, a method for assembling the draining plate 15 will be described. The draining plate 15 press-fits the draining plate 15 from the upper part of the shaft part 210 with at least the shaft part 210 passing through the through hole 36 of the lid member 30. At this time, the taper portion 211 facilitates press-fitting. And the hole which the center part of the draining board 15 enters into the groove part 212 by press injection, and an assembly | attachment is made | formed. Even when the draining plate 15 is assembled to the outer peripheral groove 212, the press-fit dimensions are provided, and the shaft portion 210 and the draining plate 15 are securely attached in close contact. Thereafter, the output shaft 12 of the electric motor 10 is inserted into the bottomed hole 213 of the shaft portion 210. The case body 50 may be assembled after the output shaft 12 is inserted into the shaft portion 210 or may be assembled before insertion.

次に、水切り板１５の作用について述べる。図２の矢印で示されるように、戻り水（ドレン水）は、蓋部材３０の貫通穴３６を通って、水切り板１５に当たる。このとき水切り板１５によって、電動モータ１０へは、水は飛散しない。一方、水切り板１５は、外周溝２１２に密着状態で圧入されている構成であるので、水は導電性の金属出力軸１２に直接かかることはなく漏電等の危険が回避できる。   Next, the operation of the draining plate 15 will be described. As shown by the arrow in FIG. 2, the return water (drain water) hits the draining plate 15 through the through hole 36 of the lid member 30. At this time, water is not scattered to the electric motor 10 by the draining plate 15. On the other hand, since the draining plate 15 is pressed into the outer peripheral groove 212 in close contact with the water, water is not directly applied to the conductive metal output shaft 12, and the risk of electric leakage or the like can be avoided.

図３は、実施例２の排水ポンプの要部拡大図である。実施例２においては、図５、６で説明した従来の排水ポンプと同一の箇所は同一の符号を付し、図５、６で説明した従来の排水ポンプと異なる箇所について説明する。   FIG. 3 is an enlarged view of a main part of the drainage pump according to the second embodiment. In the second embodiment, the same portions as those of the conventional drainage pump described with reference to FIGS. 5 and 6 are denoted by the same reference numerals, and different portions from the conventional drainage pump described with reference to FIGS.

回転羽根３００は軸部３１０を有し、軸部３１０の有底穴３１３に電動モータ１０の金属出力軸１２が挿入される。軸部３１０の電動モータ１０側の端部には、円形の水切り板３１０ａが軸部３１０と一体に成形されている。これらの材質は非導電性の樹脂等により形成される。これにより、水切り板３１０ａと軸部３１０の間は隙間が存在せずに形成されることになる。そして、実施例２においては、蓋部材３０’は、半円状に２分割される構成となっている。これにより、水切り板３１０ａと一体に成形された軸部３１０でも蓋部材３０’を取り付けることが可能となる。   The rotary blade 300 has a shaft portion 310, and the metal output shaft 12 of the electric motor 10 is inserted into the bottomed hole 313 of the shaft portion 310. A circular draining plate 310 a is formed integrally with the shaft portion 310 at the end portion of the shaft portion 310 on the electric motor 10 side. These materials are made of non-conductive resin or the like. As a result, there is no gap between the draining plate 310a and the shaft portion 310. In the second embodiment, the lid member 30 ′ is divided into two semicircles. As a result, the lid member 30 ′ can be attached even to the shaft portion 310 formed integrally with the draining plate 310 a.

次に、水切り板３１０ａの作用について述べる。戻り水（ドレン水）は、蓋部材３０の貫通穴３６を通って、水切り板３１０ａに当たる。水切り板３１０ａは、軸部３１０と一体に成形されているため、水は金属の出力軸１２に直接かかることはなく漏電等の危険が回避できる。   Next, the operation of the draining plate 310a will be described. Return water (drain water) passes through the through hole 36 of the lid member 30 and hits the draining plate 310a. Since the draining plate 310a is formed integrally with the shaft portion 310, water does not directly apply to the metal output shaft 12, and the risk of leakage etc. can be avoided.

図４は、実施例３の排水ポンプの要部拡大図である。実施例３においては、図５、６で説明した従来の排水ポンプと同一の箇所は同一の符号を付し、図５、６で説明した従来の排水ポンプと異なる箇所について説明する。   FIG. 4 is an enlarged view of a main part of the drainage pump according to the third embodiment. In the third embodiment, the same portions as those of the conventional drainage pump described with reference to FIGS. 5 and 6 are denoted by the same reference numerals, and different portions from the conventional drainage pump described with reference to FIGS.

図５、６で説明した従来の排水ポンプと異なる点は、水切り板１４と軸部１１０の端部１１１が非導電性の接着剤４１０で接着されている点である。水切り板１４は、円形であり中央部に孔を有し、この孔に出力軸１２が通るようになっている。接着剤により、軸部１１０の端部の外周と水切り板１４の下面を一周して接着されている。   A difference from the conventional drainage pump described with reference to FIGS. 5 and 6 is that the draining plate 14 and the end portion 111 of the shaft portion 110 are bonded with a non-conductive adhesive 410. The draining plate 14 is circular and has a hole at the center, and the output shaft 12 passes through the hole. The outer periphery of the end portion of the shaft portion 110 and the lower surface of the draining plate 14 are rounded and bonded by an adhesive.

さらに具体的には、図４の右側の拡大図に示されているように、水切り板１４と軸部１１０の端部１１１の間に隙間にも接着剤の一部４１１が入り込み、出力軸１２を取り囲むように被覆して確実な接着をしている。   More specifically, as shown in the enlarged view on the right side of FIG. 4, part of the adhesive 411 enters the gap between the draining plate 14 and the end 111 of the shaft 110, and the output shaft 12. It is covered so as to surround it and is securely bonded.

戻り水（ドレン水）は、蓋部材３０の貫通穴３６を通って、水切り板１４に当たる。このとき水切り板１４によって、電動モータ１０へは、水は飛散しない。一方、水切り板１４は、軸部１１０の端部の外周と全周にわたって接着剤４１０にて接着されているために、水は水切り板１４と軸部１１０の端部１１１の間に入り込まず、金属の出力軸１２に直接かかることはなく、漏電等の危険が回避できる。実施例３の構成では、図５、６で説明した従来の排水ポンプの水切り板１４と回転羽根１００の部品をそのまま使えるメリットを有する。   The return water (drain water) hits the draining plate 14 through the through hole 36 of the lid member 30. At this time, water is not scattered to the electric motor 10 by the draining plate 14. On the other hand, since the draining plate 14 is bonded by the adhesive 410 over the outer periphery and the entire periphery of the end portion of the shaft portion 110, water does not enter between the draining plate 14 and the end portion 111 of the shaft portion 110, The metal output shaft 12 is not directly applied, and the risk of leakage etc. can be avoided. The configuration of the third embodiment has an advantage that the parts of the draining plate 14 and the rotary blade 100 of the conventional drainage pump described with reference to FIGS.

以上実施例１〜３に示したように、回転羽根の軸部に水切り板を直接に装着乃至は結合させる構成とすることで、飛散水がモータの出力軸に触れることがなく、漏電等の危険が回避できる。   As shown in Embodiments 1 to 3 above, the water draining plate is directly attached to or coupled to the shaft portion of the rotary blade, so that the scattered water does not touch the output shaft of the motor, and leakage current etc. Risk can be avoided.
