本考案は、洗車機のスプレー管が、管内に残留
する水の凍結により破損することを予防するよう
にした水抜き装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a water draining device that prevents a spray pipe of a car wash machine from being damaged due to freezing of water remaining inside the pipe.
従来、洗車機のスプレー管が、寒冷時、管内に
残留する水の凍結により破損することを予防する
ため、スプレー管の基端近くに逆止弁を設け、そ
の遊端側より圧縮空気を吹き込んで、スプレー管
内の残留水を除去することは、一般に行われてい
る。
Conventionally, in order to prevent the spray pipes of car wash machines from being damaged by water remaining in the pipes freezing during cold weather, a check valve was installed near the base end of the spray pipe, and compressed air was blown into the free end of the pipe. Therefore, it is common practice to remove residual water in the spray pipe.
なお、逆止弁は、スプレー管へ吹き込まれた圧
縮空気が、水ポンプ側へ逸出することを防止する
ためのものである。 Note that the check valve is for preventing the compressed air blown into the spray pipe from escaping to the water pump side.
しかし、スプレー管内に圧縮空気を吹き込んで
も、実際には、管内の水が完全に除去されること
はなく、管内の凹所や屈曲部に残留した若干の水
や、管内面に付着している水が、時間と共に流下
して、閉じた逆止弁上に次第に溜まつて凍結し、
遂には、逆止弁やその近くのスプレー管を破損す
ることがある。
However, even when compressed air is blown into the spray pipe, the water inside the pipe is not completely removed, and some water remains in the recesses and bends inside the pipe, or adheres to the inner surface of the pipe. Water flows down over time, gradually accumulates on the closed check valve, and freezes.
Eventually, this can damage the check valve or nearby spray pipe.
本考案は、洗車機のスプレー管の基端近くの立
上り部に、弁体がばねにより付勢されて、常時は
若干開口する逆止弁を設け、かつスプレー管にお

ことにより、上述の問題点の解決を図つたもので
ある。
This invention provides a check valve whose valve body is biased by a spring at the rising part near the base end of the spray pipe of a car wash machine, and which is normally slightly open. The above-mentioned problem is solved by connecting a compressed air pipe to the air conditioner.
本考案の装置は、圧縮空気の吹き込み中は、空
気圧により逆止弁が完全に閉じるが、圧縮空気吹
き込みを停止すれば、逆止弁内に設けたばねによ

し、逆止弁上に溜まることはない。
In the device of the present invention, the check valve is completely closed by air pressure while blowing compressed air, but when the blowing of compressed air is stopped, the check valve slightly opens due to the spring installed inside the check valve. Residual water flows down and does not collect on the check valve.

Fig. 1 schematically shows a car wash device installed in a self-propelled gate-type car wash to which the present invention is applied, in which 1 is a water tank, 2 is a drain hole, 3 is a water supply pipe, and 4 is a constant water level valve. ,
Reference numeral 5 denotes a submersible pump provided in the water tank 1, and a spray pipe 7 extending upwardly and penetrating the upper plate 1a of the water tank 1 is connected to a discharge port 6 of the submersible pump 5. 8 is a nozzle of the spray pipe 7.

A check valve 9 as shown in FIG. The free end of the air pipe 11 is connected. 12
is a solenoid valve provided in the compressed air pipe 11.

る。 Figure 2 shows the check valve 9, 13 is a valve box,
14 is a valve seat, 15 is a valve body, and a weak compression spring 16 whose lower end is fixed to the upper end of the nipple 10 is provided between the valve body 15 and the lower nipple 10, and as shown in the figure, it is not always in use. The check valve 9 is slightly open.
上述の洗車装置は、洗車時は、逆止弁９が水中
ポンプ５の吐出する水流により、通常の逆止弁と
同様にさらに開口して、洗車することができる。 In the above-mentioned car washing apparatus, when washing a car, the check valve 9 is further opened by the water flow discharged from the submersible pump 5 in the same way as a normal check valve, so that the car can be washed.
水タンク１を排水し、電磁弁１２を用いて、圧
縮空気管１１より圧縮空気スプレー管７に吹き込
めば、空気圧により、弁体１５は、ばね１６に抗
して逆止弁９を閉じ、従来の水抜き装置と同様
に、スプレー管７の排水を行なう。 When the water tank 1 is drained and compressed air is blown from the compressed air pipe 11 into the spray pipe 7 using the solenoid valve 12, the air pressure causes the valve element 15 to close the check valve 9 against the spring 16, and The spray pipe 7 is drained in the same way as the water draining device.
圧縮空気の吹き込みを停止すれば、再び第２図
に示すように逆止弁９が開くので、スプレー管７
内の残留水は、逆止弁９を通過して流下し、逆止
弁９上に滞留することはない。 When the blowing of compressed air is stopped, the check valve 9 opens again as shown in FIG.
The residual water inside flows down through the check valve 9 and does not stay on the check valve 9.
なお本考案装置は、自走式門型洗車機以外の、
たとえば送水ポンプを水タンクの外部に設置し
た、定置式洗車機等にも、効果的に適用すること
ができる。 The device of this invention is suitable for applications other than self-propelled gate-type car wash machines.
For example, the present invention can be effectively applied to a stationary car wash machine in which a water pump is installed outside a water tank.
上述のように、本考案の装置は、スプレー管へ
圧縮空気の吹き込みを停止すれば、逆止弁が自動
的に開口するので、スプレー管の残留水が、逆止
弁上に滞留することがなく、寒冷時にも、逆止弁
やその近くのスプレー管が破損する恐れはない。
As mentioned above, in the device of the present invention, when the blowing of compressed air into the spray pipe is stopped, the check valve automatically opens, so that residual water in the spray pipe does not remain on the check valve. There is no risk of damage to the check valve or the spray pipe near it even in cold weather.
