【考案の詳細な説明】
本考案は空気調和機のドレン処理を簡便に行なうドレン
排水トラップに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drain trap that facilitates the drain treatment of an air conditioner.
一般に空気調和機で生成するドレンを機外に排出させる
には、機内送風機によってドレンパン部分が負圧になる
場合、ドレン配管内の臭いのある空気や機械室内の空気
が機内に逆流しないような対策が必要である。Generally, in order to discharge the condensate generated by an air conditioner to the outside of the machine, if the in-machine blower creates negative pressure in the drain pan, measures must be taken to prevent smelly air in the drain piping and air in the machine room from flowing back into the machine. is necessary.
このため従来から封水を形成するU型の排水トラップを
ドレン流出管に設けるのが通常であった。For this reason, it has conventionally been common practice to provide a U-shaped drain trap in the drain outflow pipe to form a water seal.
しかしドレン飛出管にU型トラップを設けるにはドレン
パンの位置を高くしなければならず、このために床置型
空気調和機では基礎を高くしたり、天井隠蔽型の空気調
和機では天井内空間で出来るだけ高所に据付ける考慮が
なされている。However, in order to install a U-shaped trap on the drain pipe, the position of the drain pan must be raised, and for this reason, the foundation of a floor-standing air conditioner must be raised, and the space inside the ceiling must be raised for a ceiling-hidden air conditioner. Consideration has been given to installing it as high as possible.
しかしながらこのようなドレンパンの位置を高くするこ
とには自ずと限界があり、ドレンパンの位置が低い場合
には特別の考慮が必要となる。However, there is a limit to how high the position of the drain pan can be, and special consideration is required when the position of the drain pan is low.
例えば床置型空気調和機で基礎が低い場合には第1図お
よび第2図に示すような方策が採用されてきた。For example, when a floor-standing air conditioner has a low foundation, measures such as those shown in FIGS. 1 and 2 have been adopted.
すなわち第1図の従来例ではドレンパン1内の水面2が
低いために、ドレン流出管3にU型トラップ4を1部床
スラブ5に埋設して取付けた例を示す。That is, in the conventional example shown in FIG. 1, since the water level 2 in the drain pan 1 is low, an example is shown in which a U-shaped trap 4 is partially embedded in the floor slab 5 and attached to the drain outflow pipe 3.
しかしこのように床スラブ5にU型トラップ4を埋設す
るには据付工事に手間がかかると共に機械室や防水した
床スラブを穿孔する場合には特別の注意が必要である。However, burying the U-shaped trap 4 in the floor slab 5 in this way requires a lot of effort during installation work, and special care is required when drilling holes in a machine room or a waterproof floor slab.
またドレンパン1内が負圧に保持されているときはU型
トラップ4の外方管内水面6は機内外圧差りだけ水面が
下がり、後続の横引き管7を下げかつ勾配を取るための
施工を必要とする。Furthermore, when the inside of the drain pan 1 is maintained at negative pressure, the water level 6 in the outer pipe of the U-shaped trap 4 drops by the difference in pressure between the inside and outside of the machine, and construction work is required to lower the following horizontal draw pipe 7 and take the slope. I need.
第2図は、第1図の如きU型トラップ4をスラブ5に埋
設する代りに、逆U型にトラップ4を立ちあげる従来例
を示す。FIG. 2 shows a conventional example in which the U-shaped trap 4 is erected in an inverted U-shape instead of being buried in the slab 5 as shown in FIG.
しかしトラップ4を立ち上げればそれだけドレン水面2
は上昇しく機内が負圧であれば機内外圧差りだけさらに
上昇する)、ドレンパン1の壁面を立ち上げねばならず
、機内の熱交換器の配置や機体の形状寸法に特別の考慮
か゛なされねばならない。However, if you set up trap 4, the drain water surface 2
(If the pressure inside the machine is negative, the pressure difference between the outside and outside of the machine will rise further.) Therefore, the wall of drain pan 1 must be raised, and special consideration must be given to the arrangement of the heat exchanger inside the machine and the shape and dimensions of the machine. No.
本考案の目的は、このように床置型や天井隠蔽型の空気
調和機のドレン処理にさいして、ドレンパンの位置を高
くせずとも、また第1図や第2図の如き特別のドレン排
水施工を要せずとも、極めて簡便にトラップを形成せし
めるドレン排水トラップを提供するにある。The purpose of the present invention is to eliminate the need to raise the position of the drain pan when processing drains from floor-standing or ceiling-hidden air conditioners, and to eliminate the need for special drain drainage construction as shown in Figures 1 and 2. To provide a drain trap that can be formed extremely easily without requiring a drain trap.
すなわち本考案のドレン排水トラップの要部は、空気調
和機のドレンパン内のドレンを排出するドレン流出管の
外端に、ドレン水圧が所定値を越えたときに開口し所定
値以下では閉塞する蓋を取付けて構成する。In other words, the main part of the drain trap of the present invention is a lid that opens when the drain water pressure exceeds a predetermined value and closes when the drain water pressure falls below a predetermined value, at the outer end of the drain outflow pipe that discharges the drain in the drain pan of the air conditioner. Install and configure.
以下、第3図に示した本考案のトラップの例を参照して
具体的に説明する。Hereinafter, a detailed explanation will be given with reference to an example of the trap of the present invention shown in FIG.
第3図は本考案排水トラップ例の概略断面を示しており
、空気調和機のドレンパン1から機外にドレンを排出す
る横引きドレン流出管3の外端8を外気開放容器9に導
き、この外端8に蝶番10で開閉する蓋11を取付けて
トラップを形成する。FIG. 3 shows a schematic cross section of an example of the drain trap of the present invention, in which the outer end 8 of the horizontal drain outflow pipe 3 for discharging drain from the drain pan 1 of the air conditioner to the outside of the machine is guided to the open air container 9. A trap is formed by attaching a lid 11 that opens and closes with a hinge 10 to the outer end 8.
この蓋11は外端8の開口を覆うに充分な面積を有し、
かつ外端8を閉塞したときには気密接触状態を保持する
。This lid 11 has a sufficient area to cover the opening at the outer end 8,
Moreover, when the outer end 8 is closed, an airtight contact state is maintained.
図例では外端8を若干傾斜させ(下端が突き出る)、こ
の傾斜した端面に蓋11が10を支点として自重で寄り
掛って気密を保持する例を示している。In the illustrated example, the outer end 8 is slightly inclined (the lower end protrudes), and the lid 11 rests on this inclined end surface with its own weight using the fulcrum 10 to maintain airtightness.
この本考案トラップの巧妙なる点は空気調和機内の送風
機(図示せず)によってドレンパン1の内部には負圧が
生じており(ドレンパン1の上部には熱交換器が配置さ
れ還気吸込のため負圧が生ずる)、ドレンパン1内のド
レン水面2が所定値以下となればドレン流出管3のドレ
ンはドレンパン1に向う方向の圧力がかかり、このドレ
ンの逆流により蓋11を外端8に吸引接触させる作用を
行なわせることにある。The ingenious feature of this inventive trap is that negative pressure is generated inside the drain pan 1 by the blower (not shown) in the air conditioner (a heat exchanger is placed at the top of the drain pan 1 to suck in return air). When the drain water level 2 in the drain pan 1 falls below a predetermined value, pressure is applied to the drain in the drain outlet pipe 3 in the direction toward the drain pan 1, and the backflow of this drain draws the lid 11 to the outer end 8. The purpose is to cause the action of contact to occur.
すなわち外気に開放した外端8の底端のドレンに加わる
圧力が外気と等しいとき(すなわちhだけ機内が負圧で
あるとき)には蓋11は外気圧とドレン水圧との平衡位
置で静止し、ドレン水面2が上昇すれば間欠的に蓋11
が開いてドレンを容器9内に滴下させる。That is, when the pressure applied to the drain at the bottom end of the outer end 8, which is open to the outside air, is equal to the outside air (that is, when there is a negative pressure inside the machine by h), the lid 11 remains at an equilibrium position between the outside air pressure and the drain water pressure. , if the drain water level 2 rises, the lid 11 is intermittently closed.
is opened to allow the drain to drip into the container 9.
従ってこの蓋11はドレンの水圧が所定圧以上に高まっ
たときのみにドレンを流出せしめる逆止弁の作用をなす
。Therefore, this lid 11 functions as a check valve that allows the drain to flow out only when the water pressure of the drain increases to a predetermined pressure or higher.
外気に開放した容器9内に滴下したドレンは横引き管7
によって容易に排水できる。The drain dripped into the container 9 which is open to the outside air is drained into the horizontal drain pipe 7.
can be easily drained.
なお、蓋11にスプリングを介装せしめて蓋11に弾力
をもたせかつ貯留すべきドレン量に相当する抵抗を蓋1
1に付与することもできる。In addition, a spring is interposed in the lid 11 so that the lid 11 has elasticity and a resistance corresponding to the amount of drain to be stored is applied to the lid 1.
It can also be given to 1.
またドレン流出管の外端を先細りにして開口を小さくし
たり、外端の切口の傾斜を変化させて、使用空気調和機
の特性に適応させることができる。Furthermore, the outer end of the drain outlet pipe can be tapered to make the opening smaller, or the slope of the cut at the outer end can be changed to adapt to the characteristics of the air conditioner used.
また床置型に限られず天井隠蔽型その他にも適宜使用で
きる。Moreover, it is not limited to the floor-standing type, but can also be used as a ceiling-concealed type and other types as appropriate.
このように本考案のドレン排水トラップは極めて簡単な
構造でありなから封水を簡便に形成して逆止弁の作用を
なし、かつU型l・ラップの如き必要高さを要しないの
で空気調和機のドレンパン位置をことさら高くする必要
がなく、また第1図および第2図の如き特別の施工を必
要としない。In this way, the drain trap of the present invention has an extremely simple structure, so it can easily form a water seal and act as a check valve, and it does not require the necessary height of a U-shaped l/wrap, so it can easily prevent air from entering the drain. There is no need to make the drain pan of the conditioner particularly high, and there is no need for special construction as shown in FIGS. 1 and 2.
さらにドレン流出管の外端は外気に開放する位置に設け
られるので点検や清掃が容易で取付けが簡単であり、施
工およびメインテナンスが従来例に比して極めて簡略化
する等の効果がある。Furthermore, since the outer end of the drain outflow pipe is provided at a position open to the outside air, inspection and cleaning are easy, installation is simple, and construction and maintenance are extremely simplified compared to conventional examples.
