JP 2001-65906 A

ところで、排水管を２個設けているのは、室内機の室内への取付状況に応じて、ドレンホースの引き出す方向を任意に選択できるようにするためで、ドレンホース及び閉塞栓は、室内機を据え付ける際に、付け替えられるようになっている。このため、排水管へのドレンホースの取付は、容易に、かつ確実に付け替えられるようにする必要がある。   By the way, two drain pipes are provided in order to be able to arbitrarily select the direction in which the drain hose is pulled out in accordance with the installation state of the indoor unit in the room. When installing, it can be replaced. For this reason, it is necessary to attach the drain hose to the drain pipe easily and reliably.

また、ドレンホースと排水管とのシール性は重要な課題であり、空気調和機を長期間使用しても水漏れが生じないようにすることが要求されている。   Further, the sealing performance between the drain hose and the drain pipe is an important issue, and it is required to prevent water leakage even when the air conditioner is used for a long period of time.

本発明の目的は、上述した従来の課題を解消するためになされたものであり、ドレンホースと排水管とのシール性を十分に保持するようにすると共に、ドレンホースの排水管への取付作業（付替え作業）を、容易かつ確実に行えるようにした空気調和機を提供することにある。   The object of the present invention is to solve the above-described conventional problems, and to maintain sufficient sealing performance between the drain hose and the drain pipe and to attach the drain hose to the drain pipe. An object of the present invention is to provide an air conditioner that can perform (replacement work) easily and reliably.

上記目的を達成するために、請求項１に記載の発明は、室内機に内蔵されたドレンパンを有し、このドレンパンの外方へ突出して設けられた排水管にドレンホースを取り付けるようにした空気調和機において、前記ドレンホースの端部へ、内側にシール部分が挿嵌されると共に、その外周には環状溝が設けられた前記排水管に固定される固定部分を設け、該環状溝には締付部と固定部とからなる弾性力のあるばね材で成形された取付具を設け、前記締付部は前記環状溝に取り付けられ、前記固定部は前記排水管近傍に設けられたねじ孔部に取り付けられて、前記ドレンホースを前記排水管へと固定したことを特徴とする。 In order to achieve the above-mentioned object, the invention according to claim 1 has a drain pan built in an indoor unit, and an air in which a drain hose is attached to a drain pipe that protrudes outward from the drain pan. In the conditioner, a seal portion is inserted inside the end portion of the drain hose, and a fixed portion fixed to the drain pipe provided with an annular groove is provided on the outer periphery thereof. A fixture formed of an elastic spring material composed of a fastening portion and a fixing portion is provided, the fastening portion is attached to the annular groove, and the fixing portion is a screw hole provided in the vicinity of the drain pipe. And the drain hose is fixed to the drain pipe .

請求項２に記載の発明は、請求項１に記載の空気調和機において、前記取付具はだるま形をしていることを特徴とする。 According to a second aspect of the present invention, in the air conditioner according to the first aspect of the present invention, the fixture has a daruma shape.

図３において、ドレンホース１３は、排水管１２に取り付けるための取付部２１と、その内部をドレン水が通過するためのホース部２２と、このドレンホース１３の図示しない他端側に接続される延長用ドレンホースに接続するための接続部（図示せず）とから構成されている。また取付部２１は排水管１２（図２参照）に固定される固定部分２４と、この固定部分２４に挿嵌され、排水管１２の外周に接してその接触部分をシー
ルするシール部分２５とで構成されている。固定部分２４は、ポリプロピレンを材質として円筒形状に形成され、ドレンパン１１側の端部に近接して外周には環状の溝２６が形成され、ホース部２２側の端部が階段状に縮径された形状に形成されている。 In FIG. 3, the drain hose 13 is connected to an attachment portion 21 for attaching to the drain pipe 12, a hose portion 22 for allowing drain water to pass through the inside thereof, and the other end side (not shown) of the drain hose 13. It is comprised from the connection part (not shown) for connecting to the drain hose for extension. The attachment portion 21 includes a fixed portion 24 fixed to the drain pipe 12 (see FIG. 2), and a seal portion 25 that is inserted into the fixed portion 24 and contacts the outer periphery of the drain pipe 12 to seal the contact portion. It is configured. The fixed portion 24 is formed in a cylindrical shape using polypropylene as a material, and an annular groove 26 is formed on the outer periphery in the vicinity of the end portion on the drain pan 11 side, and the end portion on the hose portion 22 side is reduced in a stepped shape. It is formed in a different shape.

前記ホース部２２は、ポリプロピレンを材質としてフレキシブルに作られ、ホース部２２の外周には断熱材が接着されて蛇腹形状に形成されている。   The hose part 22 is made of polypropylene as a material, and is formed in a bellows shape by adhering a heat insulating material to the outer periphery of the hose part 22.

前記シール部分２５は軟質のＥＰＭゴム等の材質で構成されており、固定部分２４の内側に嵌入され、接着剤を使わずにしっかりと固定される。そしてシール部分２５の内径が排水管１２の外周に水密に嵌合されるようになっている。このシール部分２５の外周には、固定部分２４の環状溝２６に対応する位置に環状溝２６の溝より幅の広い環状の凹部２７が形成されている。   The sealing portion 25 is made of a material such as soft EPM rubber, and is fitted inside the fixing portion 24 and is firmly fixed without using an adhesive. The inner diameter of the seal portion 25 is fitted to the outer periphery of the drain pipe 12 in a watertight manner. On the outer periphery of the seal portion 25, an annular recess 27 having a width wider than that of the annular groove 26 is formed at a position corresponding to the annular groove 26 of the fixed portion 24.

図２、図３において、符号３１は、ドレンホース１３を排水管１２に取り付ける際に用いる取付具、符号３２は取付ねじである。取付具３１は弾力性のある線状のばね材をだるま形に加工して作られ、大小２つのリング部３３、３４を有している。大リング部（締付部）３３の直径は、環状溝２６の底部直径より少し小さく作られ、大リング部３３を環状溝２６に外嵌したときにくい込むようになっている。小リング部（固定部）３４の直径は、取付ねじ３２のねじ部３２ｂの直径より少し大きく頭部３２ａの直径より小さくなっている。また大リング部３３には切れ目３５が設けられ、この切れ目３５により大リング部３３が広がり環状溝２６へ嵌入することができ、環状溝２６への着脱を容易にしている。   2 and 3, reference numeral 31 denotes an attachment used when the drain hose 13 is attached to the drain pipe 12, and reference numeral 32 denotes an attachment screw. The fixture 31 is made by processing an elastic linear spring material into a daruma shape, and has two large and small ring portions 33 and 34. The diameter of the large ring part (clamping part) 33 is made slightly smaller than the diameter of the bottom part of the annular groove 26, and is difficult to be inserted when the large ring part 33 is externally fitted to the annular groove 26. The diameter of the small ring portion (fixed portion) 34 is slightly larger than the diameter of the screw portion 32b of the mounting screw 32 and smaller than the diameter of the head portion 32a. Further, the large ring portion 33 is provided with a cut 35, and the large ring portion 33 can be expanded and fitted into the annular groove 26 by the cut 35, so that the attachment / detachment to the annular groove 26 is facilitated.

以上のように構成されたドレンパン１１及びドレンホース１３において、ドレンホース１３をドレンパン１１に取り付ける場合、環状溝２６に大リング部３３を嵌め込んでおく。次にドレンホース１３を排水管１２に差し込み、ドレンホース１３の一端が排水管１２のリブ１４に接するまで挿入する。小リング部３４とネジ孔部１５との位置を合わせ、取付ねじ３２を小リング部３４に挿通してネジ孔部１５にねじ止め固定する。   In the drain pan 11 and the drain hose 13 configured as described above, when the drain hose 13 is attached to the drain pan 11, the large ring portion 33 is fitted in the annular groove 26. Next, the drain hose 13 is inserted into the drain pipe 12 and inserted until one end of the drain hose 13 contacts the rib 14 of the drain pipe 12. The positions of the small ring portion 34 and the screw hole portion 15 are aligned, and the attachment screw 32 is inserted into the small ring portion 34 and fixed to the screw hole portion 15 with screws.

このようにして排水管１２にドレンホース１３を固定するので、ドレンホース１３はドレンパン１１に確実に、かつ容易に固定される。また、取付具３１がばね材で作られており、この取付具３１が取付部２１の外周からシール部分２５を介して排水管１２に押圧するので、取付部２１が排水管１２に密着してドレンホース１３と排水管１２とのシール性が十分に発揮される。   Since the drain hose 13 is fixed to the drain pipe 12 in this way, the drain hose 13 is reliably and easily fixed to the drain pan 11. Further, the fixture 31 is made of a spring material, and the fixture 31 presses against the drain pipe 12 from the outer periphery of the mount portion 21 via the seal portion 25, so that the mount portion 21 is in close contact with the drain pipe 12. The sealing performance between the drain hose 13 and the drain pipe 12 is sufficiently exhibited.

また、ドレンホース１３は取付ねじ３２を付け外しすることにより排水管１２への着脱を行うことができるので、左右の排水管１２への付け替えも簡単に行うことができる。（通常、工場出荷時、ドレンホース１３は右側の排水管１２に接続されている。）
以上、一実施例に基づいて、本発明を説明したが、本発明はこれに限定されるものでない。 Further, since the drain hose 13 can be attached to and detached from the drain pipe 12 by attaching / detaching the mounting screw 32, the drain hose 13 can be easily replaced with the left and right drain pipes 12. (Normally, the drain hose 13 is connected to the right drain pipe 12 when shipped from the factory.)
As mentioned above, although this invention was demonstrated based on one Example, this invention is not limited to this.

本実施例では、取付具３１はだるま形状に形成しているが、取付具は大小２つのリング部を有する８の字形状にして作っても良い。   In this embodiment, the fixture 31 is formed in a daruma shape, but the fixture may be formed in an 8-shaped shape having two large and small ring portions.

また、本実施例では、壁掛け形室内機で説明しているが、天井埋込形や床置き形等の他のタイプの空気調和機であっても良い。   In this embodiment, the wall-mounted indoor unit is described, but other types of air conditioners such as a ceiling-embedded type and a floor-standing type may be used.
