JP 2004-245570 A

ところで、この従来の特許文献１に記載されている空気調和装置では、空気調和装置を設置する現場において、ドレンホース０４を排水管０２に嵌め込んだ状態で、ドライバーなどの工具を用いてネジ止め作業を行う必要があり、ドレンホース０４を排水管０２に取り付けたり、また、取り外したりする作業に手間が掛かっている。さらに、空気調和装置が据え付けられた状態での、点検や修理などのサービス時に、吹き出し口などを外すことがあるが、この際にも、ドレンホースを外す必要があり、取付ネジ０８の脱着作業の手間が掛かっている。   By the way, in this conventional air conditioner described in Patent Document 1, at the site where the air conditioner is installed, with a drain hose 04 fitted into the drain pipe 02, screwing is performed using a tool such as a screwdriver. It is necessary to work, and it takes time to attach and remove the drain hose 04 to / from the drain pipe 02. Furthermore, the air outlet may be removed during service such as inspection or repair with the air conditioner installed. In this case, it is necessary to remove the drain hose, and the attachment screw 08 is removed and attached. It takes time and effort.

解決しようとする問題点は、ドレンホースの取付の際に用いられる取付具を、空気調和装置の設置される現場において、ネジ止めする必要がある点である。   The problem to be solved is that it is necessary to screw the fixture used when installing the drain hose at the site where the air conditioner is installed.

本発明の空気調和装置は、室内機（１）に内蔵されたドレンパン（１２）と、このドレンパンから外側に突出して設けられた排水管（１３）と、この排水管に取付具（３２）を用いて取り付けられるドレンホース（１６）とを備えている。前記取付具はドレンホースの外周を締め付ける締付部（３６）と、この締付部から突出する突出部（３７）とを具備している。この取付具の突出部と重なることにより、排水管に取り付けられたドレンホースの抜けを防止するストッパー（２６）が、排水管の近傍に設けられている。そして、排水管に嵌め込んだ状態でドレンホースを排水管の軸を中心として回転すると、取付具の突出部が、前記ストッパーと重なったり、ストッパーから離れたりする。   The air conditioner of the present invention includes a drain pan (12) built in the indoor unit (1), a drain pipe (13) provided to project outward from the drain pan, and a fitting (32) attached to the drain pipe. And a drain hose (16) to be attached. The fixture includes a tightening portion (36) for tightening the outer periphery of the drain hose, and a projecting portion (37) projecting from the tightening portion. A stopper (26) is provided in the vicinity of the drain pipe to prevent the drain hose attached to the drain pipe from coming off by overlapping with the protruding portion of the fixture. Then, when the drain hose is rotated around the axis of the drain pipe while being fitted in the drain pipe, the protruding portion of the fixture overlaps with the stopper or moves away from the stopper.

また、排水管の近傍にストッパー支持部（２１）が設けられ、このストッパー支持部の先端部付近から排水管の周方向に沿って両側に、前記ストッパーが張り出していることがある。   Moreover, a stopper support part (21) is provided in the vicinity of the drain pipe, and the stopper may protrude from the vicinity of the tip of the stopper support part on both sides along the circumferential direction of the drain pipe.

本発明によれば、取付具の突出部と重なることにより、排水管に取り付けられたドレンホースの抜けを防止するストッパーが、排水管の近傍に設けられているので、排水管に嵌め込んだ状態でドレンホースを排水管の軸を中心として回転させて、取付具の突出部をストッパーと重ね合わせてドレンホースの抜けを防止したり、また、取付具の突出部をストッパーから離してストッパーとの重なりを解除してドレンホースを排水管に脱着したりすることができる。その結果、空気調和装置の設置現場で、ネジ止め作業などを行わずに、簡単にドレンホースの取付・取外を行うことができる。   According to the present invention, the stopper that prevents the drain hose attached to the drain pipe from coming off by overlapping with the protruding portion of the fixture is provided in the vicinity of the drain pipe, so that the stopper is fitted in the drain pipe. Rotate the drain hose around the axis of the drain pipe to prevent the drain hose from coming off by overlapping the protruding part of the fitting with the stopper, or keep the protruding part of the fitting away from the stopper The drain hose can be detached from the drain pipe by releasing the overlap. As a result, it is possible to easily attach and remove the drain hose at the installation site of the air conditioner without performing screwing work or the like.

また、ストッパーは、ストッパー支持部の先端部付近から排水管の周方向に沿って両側に張り出しており、ドレンホースを時計方向または反時計方向の何れの方向に回転させても、取付具の突出部をストッパーに重ね合わせることができる。したがって、ドレンホースの回転方向に左右されずに、ドレンホースの取付作業を行うことができ、作業効率が向上する。   In addition, the stopper protrudes from the vicinity of the tip of the stopper support portion to both sides along the circumferential direction of the drain pipe, and the fitting protrudes regardless of whether the drain hose is rotated clockwise or counterclockwise. The part can be superimposed on the stopper. Therefore, the drain hose can be attached without being affected by the rotation direction of the drain hose, and the work efficiency is improved.

空気調和装置の設置現場でのドレンホースの取付・取外の際にネジ止め作業を不要にするという目的を、取付具の突出部と重なることによりドレンホースの抜けを防止するストッパーを排水管の近傍に設け、排水管に嵌め込んだ状態でドレンホースを排水管の軸を中心として回転させて、取付具の突出部をストッパーと重ね合わせてドレンホースの抜けを防止したり、また、取付具の突出部をストッパーから離してストッパーとの重なりを解除してドレンホースを排水管に脱着したりすることで実現した。   A stopper that prevents the drain hose from coming off by overlapping the protruding part of the fitting is used to eliminate the need for screwing when installing or removing the drain hose at the installation site of the air conditioner. Rotate the drain hose around the axis of the drain pipe while being fitted in the drain pipe, and prevent the drain hose from coming off by overlapping the protruding part of the fixture with the stopper. This was realized by removing the protrusion of the slab from the stopper, releasing the overlap with the stopper, and detaching the drain hose from the drain pipe.

FIG. 3 is a schematic cross-sectional view of a drain hose attached to a drain pipe. FIG. 4 is a front view of the fixture. FIG. 5 is an enlarged view of the vicinity of part A in FIG. 2 for explaining the drain hose mounting method. FIG. 5 (a) is a view immediately before the stopper is removed, and FIG. 5 (b) is the stopper. FIG.

図１において、空気調和装置の壁掛け型の室内機１は、本体ケース２と、この本体ケース２に取り付けられる前面パネル３及び天面パネル４とを具備している。前面パネル３には前面吸気口６が形成され、また、天面パネル４には上面吸気口７が形成されている。   In FIG. 1, a wall-mounted indoor unit 1 of an air conditioner includes a main body case 2, and a front panel 3 and a top panel 4 that are attached to the main body case 2. A front air inlet 6 is formed in the front panel 3, and a top air inlet 7 is formed in the top panel 4.

本体ケース２は横長に形成され、その内部の略中心位置に、長手方向に延設されたクロスフローファン９が回転駆動可能に設けられている。この送風機としてのクロスフローファン９と、前面吸気口６及び上面吸気口７との間に熱交換器１１が配設されている。   The main body case 2 is formed in a horizontally long shape, and a cross flow fan 9 extending in the longitudinal direction is provided at a substantially central position inside the main body case 2 so as to be rotatable. A heat exchanger 11 is disposed between the cross flow fan 9 as a blower and the front intake port 6 and the upper intake port 7.

熱交換器１１は、３つのブロックからなり、クロスフローファン９を包むように配置され、横長に細長く延在している。この熱交換器１１の下側にはドレンパン１２が設けられ、このドレンパン１２が、熱交換器１１で結露して滴下する水を受け止める。ドレンパン１２は合成樹脂にて横に細長く形成されているとともに、本体ケース２に固定される。ドレンパン１２の下部の左右両側には各々、後側に突出する円筒の排水管１３が設けられている。この排水管１３は、先端側に行くほど低くなるように傾斜している。   The heat exchanger 11 includes three blocks, is arranged so as to wrap the cross flow fan 9, and extends in a horizontally long shape. A drain pan 12 is provided below the heat exchanger 11, and the drain pan 12 receives water that is condensed and dripped by the heat exchanger 11. The drain pan 12 is formed of a synthetic resin so as to be elongated horizontally, and is fixed to the main body case 2. Cylindrical drain pipes 13 projecting to the rear side are provided on both the left and right sides of the lower part of the drain pan 12. The drain pipe 13 is inclined so as to become lower toward the tip side.

図２および図３において、排水管１３の外周には、リング状の段部１４が設けられ、この段部１４の位置までドレンホース１６の先端を嵌め込むようになっている。また、ドレンホース１６の先端部の内面にも、リング状の段部１７が形成されており、この段部１７の位置まで排水管１３の先端が挿入されるようになっている。そして、左右の排水管１３のいずれか一方を選択して、ドレンホース１６が取り付けられ、他方の排水管１３には、図示しない閉塞栓が取り付けられる。この閉塞栓はゴム製で、その外周が排水管１３の内面に接し、水蜜に取り付られる。   2 and 3, a ring-shaped step portion 14 is provided on the outer periphery of the drain pipe 13, and the tip of the drain hose 16 is fitted to the position of the step portion 14. A ring-shaped step 17 is also formed on the inner surface of the tip of the drain hose 16, and the tip of the drain pipe 13 is inserted up to the position of the step 17. Then, either one of the left and right drain pipes 13 is selected, a drain hose 16 is attached, and the other drain pipe 13 is fitted with a blocking plug (not shown). This closing plug is made of rubber, and its outer periphery contacts the inner surface of the drain pipe 13 and is attached to the nectar.

排水管１３の近傍には、円柱状のストッパー支持部２１がドレンパン１２から後側に突出している。このストッパー支持部２１の先端には、ネジ孔が設けられている。そして、ストッパー支持部２１の先端に、図５に図示するストッパー２６がネジ２７でネジ止めされる。ストッパー２６は、その中央部に、ネジ２７が挿入される貫通孔が形成されるとともに、この中央部から略円弧状に両側に張り出している。そして、ストッパー２６は、その略円弧状の部分が排水管１３の外周面に沿うように配置される。なお、ストッパー２６と排水管１３との間隔は、ドレンホース１６を排水管１３に装着することができる値（すなわち、ドレンホース１６の端部の肉厚よりも少し大きな値）に設定される。   In the vicinity of the drain pipe 13, a cylindrical stopper support portion 21 protrudes rearward from the drain pan 12. A screw hole is provided at the tip of the stopper support portion 21. Then, a stopper 26 shown in FIG. 5 is screwed to the tip of the stopper support portion 21 with a screw 27. The stopper 26 has a through-hole into which the screw 27 is inserted at the center thereof, and projects from the center to both sides in a substantially arc shape. The stopper 26 is disposed such that a substantially arc-shaped portion thereof is along the outer peripheral surface of the drain pipe 13. The interval between the stopper 26 and the drain pipe 13 is set to a value that allows the drain hose 16 to be attached to the drain pipe 13 (that is, a value slightly larger than the thickness of the end of the drain hose 16).

ドレンホース１６の端部には、その外周面にリング状の溝３１が形成され、このドレンホース１６の溝３１に、図４に図示する取付具３２が装着される。取付具３２は、ドレンホース１６の溝３１に嵌まってドレンホース１６の外周面を締め付ける締付部３６と、締付部３６から突出する突出部３７とを具備している。締付部３６は弾性を有するとともに、一部が切り欠かれたリング状をしている。そして、このリングの切欠き部とは反対側に突出部３７が締付部３６と一体に形成されるとともに、リングの径方向に外側に突出している。また、締付部３６のリングの径は、ドレンホース１６の溝３１の径よりも小さく形成され、締付部３６が溝３１に取り付けられると、ドレンホース１６の外周面を締め付ける。   A ring-shaped groove 31 is formed on the outer peripheral surface of the end portion of the drain hose 16, and a fixture 32 shown in FIG. 4 is attached to the groove 31 of the drain hose 16. The fixture 32 includes a tightening portion 36 that fits into the groove 31 of the drain hose 16 and tightens the outer peripheral surface of the drain hose 16, and a protruding portion 37 that protrudes from the tightening portion 36. The tightening portion 36 has elasticity and has a ring shape with a part cut away. A projecting portion 37 is formed integrally with the tightening portion 36 on the side opposite to the notch portion of the ring, and projects outward in the radial direction of the ring. In addition, the diameter of the ring of the tightening portion 36 is formed smaller than the diameter of the groove 31 of the drain hose 16, and when the tightening portion 36 is attached to the groove 31, the outer peripheral surface of the drain hose 16 is tightened.

この様に構成されている空気調和装置において、ドレンパン１２の排水管１３にドレンホース１６を取り付ける際には、まず初めに、ドレンホース１６の溝３１に取付具３２を装着する。ついで、ドレンホース１６の先端部を排水管１３に嵌め込み、図５（ａ）に図示する状態にする。その後、時計方向または反時計方向に、ドレンホース１６を排水管１３の軸を中心として回転させ、図５（ｂ）に図示するように、取付具３２の突出部３７がストッパー２６に重なる状態にする。この重なっている方向は、ドレンホース１６の軸方向と略平行であり、かつ、取付具３２の突出部３７は、ドレンパン１２の本体とストッパー２６との間に位置している。そのため、ドレンホース１６が排水管１３から抜ける方向に移動しようとすると、取付具３２の突出部３７がストッパー２６に係合して係止され、ドレンホース１６が排水管１３から抜けることが阻止される。   In the air conditioner configured as described above, when the drain hose 16 is attached to the drain pipe 13 of the drain pan 12, first, the fixture 32 is attached to the groove 31 of the drain hose 16. Next, the leading end of the drain hose 16 is fitted into the drain pipe 13 to obtain the state shown in FIG. Thereafter, the drain hose 16 is rotated about the axis of the drain pipe 13 in the clockwise direction or the counterclockwise direction so that the protruding portion 37 of the fixture 32 overlaps the stopper 26 as shown in FIG. To do. The overlapping direction is substantially parallel to the axial direction of the drain hose 16, and the protrusion 37 of the fixture 32 is located between the main body of the drain pan 12 and the stopper 26. Therefore, when the drain hose 16 tries to move in the direction in which the drain hose 16 is removed from the drain pipe 13, the protrusion 37 of the fixture 32 is engaged with and locked with the stopper 26, and the drain hose 16 is prevented from coming out of the drain pipe 13. The

一方、ドレンホース１６をドレンパン１２の排水管１３から取り外す際には、ドレンホース１６を排水管１３の軸を中心として回転させて、取付具３２の突出部３７をストッパー２６から遠のかせ、取付具３２の突出部３７とストッパー２６との重なりを解除する。ついで、ドレンホース１６を排水管１３から引き抜く。   On the other hand, when removing the drain hose 16 from the drain pipe 13 of the drain pan 12, the drain hose 16 is rotated around the axis of the drain pipe 13, and the protruding portion 37 of the fixture 32 is moved away from the stopper 26. The overlapping of the protrusion 37 of the tool 32 and the stopper 26 is released. Next, the drain hose 16 is pulled out from the drain pipe 13.

この様にして、ドレンホース１６を排水管１３の軸を中心として回転させることにより、簡単に抜け止めを行うことができる。したがって、ドレンホース１６の取付・取外作業が極めて簡単になる。また、ストッパー２６のネジ止めは出荷前（すなわち、メーカーの工場）で行われるため、出荷後（すなわち、空気調和装置の設置場所で）のネジ止め作業を減少させることができる。   In this manner, the drain hose 16 can be easily prevented from coming off by rotating the drain hose 16 about the axis of the drain pipe 13. Therefore, the attachment / detachment work of the drain hose 16 becomes extremely simple. Moreover, since the screwing of the stopper 26 is performed before shipment (that is, a manufacturer's factory), screwing work after shipment (that is, at the place where the air conditioner is installed) can be reduced.

また、取付具３２の締付部３６が、ドレンホース１６をその外周面から排水管１３に押圧するため、ドレンホース１６の内周面が排水管１３に密着し、ドレンホース１６と排水管１３とのシール性が十分に発揮される。   Further, since the tightening portion 36 of the fixture 32 presses the drain hose 16 from the outer peripheral surface thereof to the drain pipe 13, the inner peripheral surface of the drain hose 16 is in close contact with the drain pipe 13, and the drain hose 16 and the drain pipe 13 are in contact. Sealing performance is fully demonstrated.

以上、本発明の実施例を詳述したが、本発明は、前記実施例に限定されるものではなく、特許請求の範囲に記載された本発明の要旨の範囲内で、種々の変更を行うことが可能である。本発明の変更例を下記に例示する。
（１）ドレンホースは可撓性であるが、排水管に嵌め込むことができるならば、構造や材質などは適宜選択可能である。 As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to the said Example, A various change is performed within the range of the summary of this invention described in the claim. It is possible. Examples of modifications of the present invention are illustrated below.
(1) Although the drain hose is flexible, the structure and material can be appropriately selected as long as the drain hose can be fitted into the drain pipe.

（２）室内機１は、必ずしも壁掛け型室内機である必要はなく、たとえば、天井埋込型や床置き型などの他の型式でも可能である。
（３）取付具３２の締付部３６は、ドレンホース１６の外周面を締め付けることができるならば、その形状、材質や構造などは適宜選択可能である。たとえば、取付具３２は、板金やバネ材などで形成される。 (2) The indoor unit 1 does not necessarily need to be a wall-mounted indoor unit, and may be another type such as a ceiling-embedded type or a floor-standing type.
(3) As long as the fastening part 36 of the fixture 32 can fasten the outer peripheral surface of the drain hose 16, the shape, material, structure, etc. can be selected suitably. For example, the fixture 32 is formed of a sheet metal or a spring material.

（４）取付具３２の突出部３７およびストッパー２６は、重なることにより、ドレンホース１６の抜け止めを行うことができ、かつ、排水管１３の軸を中心としてドレンホース１６を回転させて、突出部３７とストッパー２６との重なりを解除できるならば、その形状、材質や構造などは適宜選択可能である。たとえば、ストッパー２６はストッパー支持部２１にネジ止めされているが、ストッパー２６とストッパー支持部２１とを一体成形することも可能である。また、ストッパー２６を板金で形成したり、樹脂で形成したりすることが可能である。 (4) The protrusion 37 and the stopper 26 of the fixture 32 can overlap to prevent the drain hose 16 from coming off, and the drain hose 16 is rotated around the axis of the drain pipe 13 to protrude. If the overlap between the portion 37 and the stopper 26 can be released, its shape, material, structure, etc. can be selected as appropriate. For example, although the stopper 26 is screwed to the stopper support portion 21, the stopper 26 and the stopper support portion 21 can be integrally formed. Further, the stopper 26 can be formed of sheet metal or resin.

（５）ストッパー２６はストッパー支持部２１の先端部付近から両側に張り出しているが、一方の側のみに張り出すことも可能である。ただし、両側に張り出していると、ドレンホース１６を時計方向または反時計方向の何れの方向に回しても、ストッパー２６を取付具３２の突出部３７に重ね合わせることができる。したがって、ストッパー２６は両側に張り出していることが好ましい。
（６）ドレンパンは、少なくとも一本の排水管を具備していれば、その材質や構造などは適宜変更可能である。 (5) Although the stopper 26 protrudes from the vicinity of the tip end portion of the stopper support portion 21 to both sides, it can be extended only to one side. However, when protruding from both sides, the stopper 26 can be overlapped with the protruding portion 37 of the fixture 32 even if the drain hose 16 is rotated clockwise or counterclockwise. Therefore, it is preferable that the stopper 26 protrudes on both sides.
(6) As long as the drain pan has at least one drain pipe, its material, structure, and the like can be appropriately changed.
