For example, when cleaning an automobile, dirt such as mud adhering to the vehicle body should be washed off with high-temperature water jetted at high pressure, but these electronic parts are not damaged when cleaning an engine room with many electronic parts. To do so, steam with a lower (impact) pressure than hot water is used.
Therefore, it is necessary to use a high-temperature water washer and a steam washer according to the object to be cleaned. Especially when high-temperature water and steam are used alternately many times, work efficiency is low and extra There was a problem that fuel consumption increased. In addition, since at least two devices are required, there is a drawback that installation costs are high and it is difficult to install in a small place.
Then, an object of this invention is to provide the fluid washing machine which can switch a hot water and a vapor | steam easily and rapidly and can inject.

  In order to achieve the above object, a fluid washing machine according to the present invention includes a flexible hose, a nozzle attached to the tip of the flexible hose, a high-temperature water generator that generates high-temperature water, and the high-temperature water generator. A steam generating device that reheats the high-temperature water generated in step 1 to generate steam, and has switching means for selectively switching between high-temperature water and steam and ejecting from the nozzle through the flexible hose. Is.

Moreover, the said high temperature water production | generation apparatus consists of boilers, and the said steam production | generation apparatus is shared and comprised the casing burner of the said boiler.
Moreover, the said steam production | generation apparatus has an electrical resistance type or an electromagnetic induction type heating part.

Even if you do not prepare a cleaning machine, you can instantly switch between high-temperature water and steam with a single cleaning machine (of the present invention), increasing the cleaning work efficiency (speed), and in a narrow space Can also be installed.
In addition, when switching from high temperature water to steam, the high temperature water generated by the high temperature water generator is reheated by the steam generator to generate steam, so the time and fuel (cost) required for steam generation And can be greatly reduced.
In addition, after washing with high-temperature water, the object to be cleaned can be quickly dried by spraying steam onto the object to be cleaned (machine, floor surface, etc.). In particular, when the heating unit 9 is of an electromagnetic induction type, the cleaning operation efficiency is further improved by switching to the ejection of steam within a short second (instantly) after cleaning with high-temperature water.

Can be reduced. Furthermore, since the high-temperature water generator 1 and the steam generator 2 are configured to share the boiler 6, the structure of the fluid washer can be simplified and the size can be reduced.

  Moreover, since the steam generator 2 has the electrical resistance type or electromagnetic induction type heating unit 9, the high-temperature water generated by the boiler 6 is heated again by the boiler 6 and the heating unit 9, and the high-temperature superheated steam is generated. Can be generated quickly and efficiently. Moreover, since the electrical resistance type or electromagnetic induction type heating unit 9 is used, generation of exhaust gas is reduced and suppressed, which is preferable for the environment.
