塩水噴霧装置は、塗装板金のような試料に対して、塩水噴霧−熱風乾燥−湿潤のサイクルを繰り返し、耐食性を試験するのに用いられる。
しかし、上記従来の塩水噴霧装置では、塩水噴霧を休止している間、特に熱風乾燥時に、ノズルの先端部に塩が析出し、ノズルを詰まらせることがある問題点があった。
そこで、本発明の目的は、塩の析出によるノズルの詰まりを防止できる塩水噴霧装置を提供することにある。 The salt spray device is used to test the corrosion resistance of a sample such as a coated sheet metal by repeating a salt spray-hot air drying-wetting cycle.
However, the conventional salt spray device has a problem in that salt is deposited on the tip of the nozzle and clogs the nozzle while the salt spray is stopped, particularly during hot air drying.
Then, the objective of this invention is providing the salt spray apparatus which can prevent clogging of the nozzle by precipitation of salt.

第１の観点では、本発明は、塩水を吐出する塩水ノズルと、前記塩水ノズルの近傍に空気を噴出して前記塩水ノズルから吐出された塩水を霧状にして飛ばす空気ノズルと、前記塩水ノズルに向けて洗浄水を吹き掛ける洗浄水ノズルとを具備したことを特徴とする塩水噴霧装置を提供する。
上記第１の観点による塩水噴霧装置では、塩水の噴霧を休止している間に、洗浄水ノズルから塩水ノズルに向けて洗浄水を吹き掛けることにより、ノズルの先端部に塩が析出するのを防止できるか又は析出した塩を洗い流すことが出来る。よって、塩の析出によるノズルの詰まりを防止できる。 In a first aspect, the present invention includes a salt water nozzle that discharges salt water, an air nozzle that ejects air in the vicinity of the salt water nozzle and sprays the salt water discharged from the salt water nozzle in a mist, and the salt water nozzle. A salt spray device comprising a cleaning water nozzle for spraying cleaning water toward the surface is provided.
In the salt spray device according to the first aspect, the salt is deposited on the tip of the nozzle by spraying the wash water from the wash water nozzle toward the salt water nozzle while the spray of salt water is stopped. It can be prevented or the precipitated salt can be washed away. Therefore, clogging of the nozzle due to salt precipitation can be prevented.

第２の観点では、本発明は、前記第１の観点による塩水噴霧装置において、前記塩水ノズルおよび前記空気ノズルを覆うと共に前記空気ノズルの空気噴出方向のみに開口を有するフードを具備し、前記洗浄水ノズルは前記開口を通して前記塩水ノズルに向けて洗浄水を吹き掛けることを特徴とする塩水噴霧装置を提供する。
上記第２の観点による塩水噴霧装置では、不要な方向への塩水霧の飛散をフードにより防止できる。また、フードの開口を通して洗浄水をノズルに吹き掛けるので、フード付の塩水噴霧器でも、塩の析出によるノズルの詰まりを防止できる。さらに、不要な方向への洗浄水の飛散をフードにより防止できる。 According to a second aspect, the present invention provides the salt spray apparatus according to the first aspect, further comprising a hood that covers the salt water nozzle and the air nozzle and has an opening only in an air ejection direction of the air nozzle, The water nozzle provides a salt spray device, wherein the cleaning water is sprayed toward the salt water nozzle through the opening.
In the salt spray device according to the second aspect, the hood can prevent salt water mist from being scattered in unnecessary directions. Further, since the cleaning water is sprayed to the nozzle through the opening of the hood, the clogging of the nozzle due to salt precipitation can be prevented even in a salt water sprayer with a hood. Furthermore, the hood can prevent the cleaning water from splashing in unnecessary directions.

本発明の塩水噴霧装置によれば、洗浄水ノズルから塩水ノズルに向けて洗浄水を吹き掛けることにより、ノズルの先端部に塩が析出するのを防止できるか又は析出した塩を洗い流すことが出来る。よって、塩の析出によるノズルの詰まりを防止することが出来る。   According to the salt spray device of the present invention, by spraying wash water from the wash water nozzle toward the salt water nozzle, it is possible to prevent salt from depositing on the tip of the nozzle or to wash away the deposited salt. . Therefore, clogging of the nozzle due to salt precipitation can be prevented.

以下、図に示す実施の形態により本発明をさらに詳細に説明する。なお、これにより本発明が限定されるものではない。   Hereinafter, the present invention will be described in more detail with reference to embodiments shown in the drawings. Note that the present invention is not limited thereby.
