Description

【０００１】
【発明の属する技術分野】
本発明は、空気調和機のドレン水処理装置に関し、さらに詳しくは送風機の負圧側に設けたドレン水処理装置に関する。
【０００２】
【従来の技術】
従来の空気調和機およびそのドレン水処理装置について、図６、図７を用いて説明する。
【０００３】
図６は空気調和機の概略構成を示す縦断面図であり、空気調和機１は、送風機２、熱交換器３を本体ケーシング４の内部に設置しており、熱交換器３からのドレン水を受ける水受け皿５を熱交換器３の下部に配置し、水受け皿５に溜まったドレン水をケーシング４の外部へ排出するドレン排水口６を設けている。
【０００４】
図７（ａ）は上記した水受け皿５とドレン排水口６とからなるドレン水処理装置の斜視図であり、図７（ｂ）はそのＥ−Ｅ断面図である。ドレン排水口６は管体であり、直径方向に沿う仕切り板７によって排水経路８と空気経路９とに分離している。排水経路８の上端は水受け皿４の底部に開口しており、空気経路９の上端は水受け皿５に溜まるドレン水の最高水面より高くなるように水受け皿５の縁部より高く配置している。この構成により、ドレン排水口６の入口側が負圧であっても、空気経路９から空気を吸い込み、ドレン水を排水経路８のみから排出することができ、しかも仕切り板７がドレン水の案内の役割を果たすため、スムーズなドレン水処理が可能となっている。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記したような従来のドレン水処理装置では、ドレン排水口６の入口側が負圧になると、ドレン水の排出量が多い時（連続運転時）には問題なく排水経路を通じて排出できるものの、空気調和機の停止時やドレン水の排出量が少ない時には、仕切り板７についたドレン水が流れ落ちず、流入空気の圧力に負けて出口側の端面で表面張力により水膜Ｗ１を形成し、空気経路９側に逆流してしまう。また、形成された水膜Ｗ１が流入空気により破れ、その時に発生するポコポコという音が居室空間にて反響する。
【０００６】
ドレン排水口６の入口側が負圧でない場合でも、気密性の高いマンションでレンジフードを運転させた時などに、吸い込まれる気流にドレン排水口６の周囲の空気が引っ張られて上記と同じ状態となり、ドレン水を排出できないことがある。
【０００７】
本発明は、このような問題点に鑑みてなされたものであり、ドレン水を水膜状態としたり、空気経路側に逆流させることなく、円滑に静かに排出できる空気調和機のドレン水処理装置を提供することを目的としている。
【０００９】
上記課題を解決するために、請求項１に記載の発明は、送風機と熱交換器とを備えた空気調和機の本体内部に設けられ前記熱交換器からのドレン水を受ける水受け皿と、この水受け皿のドレン水を本体外部へ排出するドレン排水口とを有し、前記ドレン排水口を仕切部により排水経路と空気経路とに分離した空気調和機のドレン水処理装置において、前記ドレン排水口を上下方向に設け、前記仕切部の両側でドレン排水口の壁部の長さを相違させ、前記水受け皿より出口側の排水経路を空気経路よりも長く構成したことを特徴とする。
【００１０】
請求項２に記載の発明は、送風機と熱交換器とを備えた空気調和機の本体内部に設けられ前記熱交換器からのドレン水を受ける水受け皿と、この水受け皿のドレン水を本体外部へ排出するドレン排水口とを有し、前記ドレン排水口を仕切部により排水経路と空気経路とに分離した空気調和機のドレン水処理装置において、前記ドレン排水口を上下方向に設け、前記空気経路を構成するドレン排水口の出口側の壁部に切欠き部を形成したことを特徴とする。
【００１２】
【発明の実施の形態】
以下、本発明の実施の形態について、図面を参照しながら説明する。
図１は本発明にかかる空気調和機の概略構成を示す縦断面図であり、空気調和機１は、先に図６を用いて説明した従来のものと同様に、送風機２、熱交換器３を本体ケーシング４の内部に設置している。また、熱交換器３からのドレン水を排出する本発明の実施の形態１におけるドレン水処理装置として、熱交換器３からのドレン水を受ける水受け皿５を熱交換器３の下方に配置し、水受け皿５に溜まったドレン水をケーシング４の外部へ排出するドレン排水口６を設けている。このドレン水処理装置は送風機２の負圧側に位置している。
【００１３】
図２（ａ）は上記したドレン水処理装置の斜視図であり、図２（ｂ）はそのＡ−Ａ断面図である。ドレン排水口６は水受け皿５の底部に開口した上下方向の管体であり、このドレン排水口６を直径方向に沿う仕切り板７によって排水経路８と空気経路９とに分離している。
【００１４】
仕切り板７の下端はドレン排水口６の出口側の端面より突出していて、ドレン排水口６の長さをＬ１、仕切り板７の長さをＬ２で表わすと、Ｌ１＜Ｌ２となっている。仕切り板７の上端は水受け皿５の縁部より高く配置し、空気経路９側のドレン排水口６の壁部は仕切り板７の上端と同じ高さまで配置していて、空気経路９の上端を、水受け皿５に溜まるドレン水の最高水面より高くしている。
【００１５】
このようなドレン水処理装置では、ドレン排水口６の出口側の端面と仕切り板７の下端とに段差があるため、空気調和機１（送風機２、熱交換器３）の停止時やドレン水の排出量が少ない時も、排水経路８内で仕切り板７についたドレン水が流れ落ちずに、空気圧に負けてドレン排水口６の出口側の端面で水膜となるのを防止できる。またドレン水は仕切り板７の突出にはばまれ空気経路９側に逆流しにくくなり、このことによっても、水膜状態となるのを防止できる。水膜形成は、仕切り板７の長さＬ２がドレン排水口６の長さＬ１より長くなるほど起こりにくい。
【００１６】
したがって、従来の問題であった、空気の流入によって水膜が破れる現象は起こらず、水膜が破れる時に発生していたポコポコという音はせず、ドレン水を円滑に静かに排出することができる。
【００１７】
またこのとき、上記したように空気経路９の上端をドレン水の最高水面より高くしているので、空気経路９の上端から流出する空気が水受け皿５内のドレン水を外に飛散させることもない。
【００１８】
図３（ａ）は本発明の実施の形態２におけるドレン水処理装置の斜視図であり、図３（ｂ）はそのＢ−Ｂ断面図である。
このドレン水処理装置では、上記実施の形態１のドレン水処理装置と同様に、上下方向のドレン排水口６を仕切り板７によって排水経路８と空気経路９とに分離している。また、仕切り板７の上端は水受け皿５の縁部より高く配置し、空気経路９側のドレン排水口６の壁部は仕切り板７の上端と同じ高さまで配置することで、空気経路９の上端を、水受け皿５に溜まるドレン水の最高水面より高くしている。
【００１９】
このドレン水処理装置が上記実施の形態１のドレン水処理装置と相違するのは、水受け皿５よりも出口側において、仕切り板７の両側でドレン排水口６の壁部の長さを相違させることで、すなわち、空気経路９側のドレン排水口６の壁部の下端は仕切り板７の下端より高く、排水経路８側のドレン排水口６の壁部の下端は仕切り板７の下端と同じ高さとすることで、空気経路９の長さＬ３＜排水経路８の長さＬ４とした点である。
【００２０】
このようなドレン水処理装置では、排水経路８の端面部分と空気経路９の端面部分とが離れた位置となるため、上記と同様に、ドレン排水口６の出口側の端面部での水膜の形成、および空気経路９へのドレン水の逆流を防止することができ、ドレン水を円滑に静かに排出することができる。水膜形成は、排水経路８の長さＬ４が空気経路９の長さＬ３より長くなるほど起こりにくい。
【００２１】
図４（ａ）は本発明の実施の形態３におけるドレン水処理装置の斜視図であり、図４（ｂ）はそのＣ−Ｃ断面図である。
このドレン水処理装置では、上記ドレン水処理装置と同様に、上下方向のドレン排水口６を仕切り板７によって排水経路８と空気経路９とに分離している。また、仕切り板７の上端は水受け皿５の縁部より高く配置し、空気経路９側のドレン排水口６の壁部は仕切り板７の上端と同じ高さまで配置することで、空気経路９の上端を、水受け皿５に溜まるドレン水の最高水面より高くしている。
【００２２】
このドレン水処理装置が上記実施の形態１のドレン水処理装置と相違するのは、水受け皿５よりも出口側において、空気経路９を構成するドレン排水口６の壁部の下端に上下方向に細長い切欠き部１０を設けた点である。
【００２３】
このようなドレン水処理装置では、切欠き部１０より空気経路９を通じて常に空気が流入するので、ドレン排水口６の出口側の端面部での水膜の形成、空気経路９へのドレン水の逆流を防止することができ、ドレン水を円滑に静かに排出することができる。
【００２４】
図５（ａ）は本発明の実施の形態４におけるドレン水処理装置の斜視図であり、図５（ｂ）はそのＤ−Ｄ断面図である。
このドレン水処理装置では、上記実施の形態１のドレン水処理装置と同様に、上下方向のドレン排水口６を仕切り板７によって排水経路８と空気経路９とに分離している。また、仕切り板７の上端は水受け皿５の縁部より高く配置し、空気経路９側のドレン排水口６の壁部は仕切り板７の上端と同じ高さまで配置することで、空気経路９の上端を、水受け皿５に溜まるドレン水の最高水面より高くしている。
【００２５】
このドレン水処理装置が上記実施の形態１のドレン水処理装置と相違するのは、水受け皿５よりも出口側においてドレン排水口６を横向きにケーシング４の外部に導き、排水経路８を下側に配置し空気経路９を上側に配置するとともに、仕切り板７の両側でドレン排水口６の壁部の長さを相違させることで、横向きの空気経路９の長さＬ５＜排水経路８の長さＬ６とした点である。
【００２６】
このようなドレン水処理装置では、ドレン水は水受け皿５から排水経路８に流れ込みその端部より下方へ流れることになり、ドレン排水口６の出口側の端面部で水膜を形成したり、上側の空気経路９へ逆流することはなく、ドレン水を円滑に静かに排出することができる。
【００２７】
なお、上記各実施形態を示す図１〜図５ではドレン排水口６を一体成形品の状態で示したが、これは、水受け皿５やケーシング４への取り付けを一体的に行なえることを利点とするもので、このような構成に限定されない。例えば、排水経路８と空気経路９のそれぞれを独立した管体とし接合させたり、または、空気経路９を独立した管体として、同じく管体であるドレン排水口６の内周に接して設置したり、あるいはドレン排水口６の内周より離間させて設置してもよく、いずれの場合も、上述したのと同様の効果が得られる。
【００２８】
【発明の効果】
以上のように本発明によれば、ドレン排水口の端面と仕切部との間に段差を設けることにより、ドレン排水口の端面での水膜の形成や、空気経路へのドレン水の逆流を防止することができ、ドレン水を円滑に静かに排出することができる。
【００２９】
排水経路を空気経路より長く構成することにより、両経路の端面を互いに離間させて、ドレン排水口の端面での水膜の形成や、空気経路へのドレン水の逆流を防止することができ、ドレン水を円滑に静かに排出することができる。
【００３０】
空気経路側のドレン排水口の壁部に切欠き部を設けることにより、この切欠き部より常に空気を流入させて、ドレン排水口の端面で水膜が形成し始めても保持させず、そのドレン水の空気経路への逆流を防止することができ、ドレン水を円滑に静かに排出することができる。
【００３１】
ドレン排水口を横向きとし、下側に排水経路を配置し上側に空気経路を配置することにより、下側にある排水経路を通じて、ドレン水を円滑に静かに排出することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a drain water treatment device for an air conditioner, and more particularly to a drain water treatment device provided on the negative pressure side of a blower.
[0002]
[Prior art]
A conventional air conditioner and its drain water treatment device will be described with reference to FIGS.
[0003]
FIG. 6 is a longitudinal sectional view showing a schematic configuration of the air conditioner. In the air conditioner 1, a blower 2 and a heat exchanger 3 are installed inside a main casing 4, and drain water from the heat exchanger 3 is provided. A water receiving tray 5 for receiving the water is disposed below the heat exchanger 3, and a drain drain port 6 for discharging the drain water accumulated in the water receiving tray 5 to the outside of the casing 4 is provided.
[0004]
Fig.7 (a) is a perspective view of the drain water processing apparatus which consists of the above-mentioned water receiving tray 5 and the drain discharge port 6, FIG.7 (b) is the EE sectional drawing. The drain drain port 6 is a tubular body, and is separated into a drain path 8 and an air path 9 by a partition plate 7 along the diameter direction. The upper end of the drainage path 8 opens at the bottom of the water tray 4, and the upper end of the air path 9 is arranged higher than the edge of the water tray 5 so as to be higher than the highest water level of the drain water collected in the water tray 5. . With this configuration, even if the inlet side of the drain outlet 6 is under negative pressure, air can be sucked from the air path 9 and drain water can be discharged only from the drain path 8, and the partition plate 7 can guide the drain water. Because it plays a role, smooth drain water treatment is possible.
[0005]
[Problems to be solved by the invention]
However, in the conventional drain water treatment apparatus as described above, when the drain side of the drain discharge port 6 has a negative pressure, it can be discharged through the drainage path without problems when the drain water discharge amount is large (during continuous operation). When the air conditioner is stopped or when the amount of drain water discharged is small, the drain water attached to the partition plate 7 does not flow down, and the water film W1 is formed by the surface tension at the end face on the outlet side under the pressure of the inflowing air. It will flow backward to the path 9 side. Further, the formed water film W1 is broken by the inflowing air, and a popping sound generated at that time echoes in the room space.
[0006]
Even when the inlet side of the drain outlet 6 is not under negative pressure, when the range hood is operated in a highly airtight apartment, the air around the drain outlet 6 is pulled by the air sucked into the same state as above. , Drain water may not be discharged.
[0007]
The present invention has been made in view of such problems, and the drain water treatment apparatus for an air conditioner that can smoothly and smoothly discharge drain water without making it into a water film state or backflowing to the air path side. The purpose is to provide.
[0009]
In order to solve the above-mentioned problem, the invention according to claim 1 is provided in a body of an air conditioner including a blower and a heat exchanger, and receives a drain water from the heat exchanger. In the drain water treatment apparatus for an air conditioner, having a drain drain port for draining drain water from a water tray to the outside of the main body, and separating the drain drain port into a drain path and an air path by a partition portion, the drain drain port Is provided in the vertical direction, the length of the wall of the drain outlet is made different on both sides of the partition, and the drainage path on the outlet side from the water tray is longer than the air path.
[0010]
The invention according to claim 2 is a water receiving tray that is provided inside a main body of an air conditioner including a blower and a heat exchanger and receives drain water from the heat exchanger, and the drain water of the water receiving tray is disposed outside the main body. A drain water treatment apparatus for an air conditioner in which the drain drain port is separated into a drainage path and an air path by a partition, and the drain drainage port is provided in a vertical direction, and the air A notch is formed in the wall on the outlet side of the drain outlet that constitutes the path.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a longitudinal sectional view showing a schematic configuration of an air conditioner according to the present invention. The air conditioner 1 is similar to the conventional one described with reference to FIG. Is installed inside the main casing 4. In addition, as a drain water treatment device in Embodiment 1 of the present invention that discharges drain water from the heat exchanger 3, a water tray 5 that receives drain water from the heat exchanger 3 is disposed below the heat exchanger 3. A drain discharge port 6 for discharging drain water accumulated in the water tray 5 to the outside of the casing 4 is provided. This drain water treatment device is located on the negative pressure side of the blower 2.
[0013]
Fig.2 (a) is a perspective view of an above-mentioned drain water treatment apparatus, FIG.2 (b) is the AA sectional drawing. The drain drain port 6 is a vertical pipe body opened at the bottom of the water tray 5, and the drain drain port 6 is separated into a drain path 8 and an air path 9 by a partition plate 7 along the diameter direction.
[0014]
The lower end of the partition plate 7 protrudes from the end face on the outlet side of the drain drain port 6. When the length of the drain drain port 6 is represented by L1 and the length of the partition plate 7 is represented by L2, L1 <L2. The upper end of the partition plate 7 is disposed higher than the edge of the water tray 5, the wall of the drain outlet 6 on the air path 9 side is disposed at the same height as the upper end of the partition plate 7, and the upper end of the air path 9 is The drain water collected in the water tray 5 is higher than the maximum water level.
[0015]
In such a drain water treatment apparatus, since there is a step between the end face on the outlet side of the drain drain port 6 and the lower end of the partition plate 7, the air conditioner 1 (blower 2, heat exchanger 3) is stopped or drain water is used. Even when the amount of discharged water is small, the drain water attached to the partition plate 7 does not flow down in the drainage path 8, and it is possible to prevent a drainage from being caused to form a water film on the end face on the outlet side of the drain drain port 6. Further, the drain water is blocked by the projection of the partition plate 7 and hardly flows back to the air path 9 side, and this can also prevent the water film state. The formation of the water film hardly occurs as the length L2 of the partition plate 7 becomes longer than the length L1 of the drain drain port 6.
[0016]
Therefore, the phenomenon that the water film breaks due to the inflow of air, which was a conventional problem, does not occur, and the drain water that is generated when the water film is broken does not sound, and the drain water can be discharged smoothly and quietly. .
[0017]
At this time, since the upper end of the air path 9 is made higher than the highest water surface of the drain water as described above, the air flowing out from the upper end of the air path 9 may cause the drain water in the water tray 5 to be scattered outside. Absent.
[0018]
Fig.3 (a) is a perspective view of the drain water treatment apparatus in Embodiment 2 of this invention, FIG.3 (b) is the BB sectional drawing.
In this drain water treatment apparatus, the drain drain port 6 in the vertical direction is separated into a drain path 8 and an air path 9 by a partition plate 7 as in the drain water treatment apparatus of the first embodiment. Moreover, the upper end of the partition plate 7 is disposed higher than the edge of the water tray 5, and the wall portion of the drain drain port 6 on the air path 9 side is disposed to the same height as the upper end of the partition plate 7. The upper end is made higher than the highest water level of the drain water collected in the water tray 5.
[0019]
This drain water treatment apparatus is different from the drain water treatment apparatus of the first embodiment in that the length of the wall portion of the drain discharge port 6 is different on both sides of the partition plate 7 on the outlet side of the water tray 5. That is, the lower end of the wall portion of the drain drain port 6 on the air path 9 side is higher than the lower end of the partition plate 7, and the lower end of the wall portion of the drain drain port 6 on the drain channel 8 side is the same as the lower end of the partition plate 7. By setting the height, the length L3 of the air path 9 is smaller than the length L4 of the drainage path 8.
[0020]
In such a drain water treatment apparatus, since the end surface portion of the drainage passage 8 and the end surface portion of the air passage 9 are separated from each other, the water film at the end surface portion on the outlet side of the drain drainage port 6 is the same as described above. And the backflow of drain water to the air path 9 can be prevented, and the drain water can be smoothly and gently discharged. The water film formation is less likely to occur as the length L4 of the drainage path 8 becomes longer than the length L3 of the air path 9.
[0021]
FIG. 4A is a perspective view of a drain water treatment apparatus according to Embodiment 3 of the present invention, and FIG. 4B is a CC cross-sectional view thereof.
In this drain water treatment apparatus, the drain drain port 6 in the vertical direction is separated into a drain path 8 and an air path 9 by a partition plate 7 as in the drain water treatment apparatus. Moreover, the upper end of the partition plate 7 is disposed higher than the edge of the water tray 5, and the wall portion of the drain drain port 6 on the air path 9 side is disposed to the same height as the upper end of the partition plate 7. The upper end is made higher than the highest water level of the drain water collected in the water tray 5.
[0022]
This drain water treatment apparatus is different from the drain water treatment apparatus of the first embodiment in that the outlet side of the water tray 5 is located in the vertical direction at the lower end of the wall portion of the drain outlet 6 constituting the air passage 9. This is the point that an elongated notch 10 is provided.
[0023]
In such a drain water treatment apparatus, air always flows from the notch 10 through the air path 9, so that a water film is formed at the end face on the outlet side of the drain outlet 6, and drain water to the air path 9 is formed. Backflow can be prevented, and drain water can be smoothly and gently discharged.
[0024]
Fig.5 (a) is a perspective view of the drain water treatment apparatus in Embodiment 4 of this invention, FIG.5 (b) is the DD sectional drawing.
In this drain water treatment apparatus, the drain drain port 6 in the vertical direction is separated into a drain path 8 and an air path 9 by a partition plate 7 as in the drain water treatment apparatus of the first embodiment. Moreover, the upper end of the partition plate 7 is disposed higher than the edge of the water tray 5, and the wall portion of the drain drain port 6 on the air path 9 side is disposed to the same height as the upper end of the partition plate 7. The upper end is made higher than the highest water level of the drain water collected in the water tray 5.
[0025]
This drain water treatment device is different from the drain water treatment device of the first embodiment in that the drain discharge port 6 is guided laterally outside the casing 4 on the outlet side of the water tray 5 and the drainage path 8 is on the lower side. And the air path 9 on the upper side, and the length of the wall of the drain outlet 6 on both sides of the partition plate 7 is made different so that the length L5 of the sideways air path 9 <the length of the drainage path 8 This is the point that is L6.
[0026]
In such a drain water treatment device, the drain water flows into the drainage path 8 from the water tray 5 and flows downward from the end thereof, and forms a water film at the end surface portion on the outlet side of the drain drainage port 6, The drain water does not flow back to the upper air path 9, and the drain water can be discharged smoothly and quietly.
[0027]
1 to 5 showing the above embodiments, the drain outlet 6 is shown as an integrally molded product, but this is advantageous in that it can be attached to the water tray 5 and the casing 4 integrally. However, the present invention is not limited to such a configuration. For example, each of the drainage path 8 and the air path 9 is joined as an independent pipe, or the air path 9 is installed as an independent pipe in contact with the inner periphery of the drain drain port 6 that is also a pipe. Alternatively, it may be installed away from the inner periphery of the drain outlet 6, and in either case, the same effect as described above can be obtained.
[0028]
【The invention's effect】
As described above, according to the present invention, by providing a step between the end surface of the drain outlet and the partition portion, the formation of a water film on the end face of the drain outlet and the reverse flow of the drain water to the air path are performed. Therefore, drain water can be discharged smoothly and quietly.
[0029]
By configuring the drainage path to be longer than the air path, the end surfaces of both paths can be separated from each other to prevent the formation of a water film at the end face of the drain drainage port and the backflow of drain water to the air path. Drain water can be discharged smoothly and quietly.
[0030]
By providing a notch in the wall of the drain outlet on the air path side, air is always allowed to flow in from the notch, and even if a water film starts to form at the end face of the drain outlet, the drain is not retained. Backflow of water into the air path can be prevented, and drain water can be discharged smoothly and quietly.
[0031]
By arranging the drain outlet sideways, disposing the drainage path on the lower side and the air path on the upper side, the drain water can be smoothly and smoothly discharged through the drainage path on the lower side.
