That is, when producing steam ST in heating unit 5, before supply running water, first make heating unit 5 sky burn, make the temperature of pipe portion 54a increase.That is, by making heating element heater 55 be energized, aluminum hull 54 is heated due to heat trnasfer, and pipe portion 54a (flow path surfaces) is heated.After the temperature of pipe portion 54a rises to set point of temperature (maximum), ON/OFF control is carried out to cooling water electromagnetic valve 4e, the running water of ormal weight is supplied to pipe portion 54a via heat-resistant hose 57.In addition, ormal weight refers to the amount (on a small quantity) that can produce steam.When a small amount of running water is supplied to pipe portion 54a, running water gasifies, and produces water vapour (steam ST).In this case, when supplying running water to pipe portion 54a, the flow path surfaces temperature of pipe portion 54a reduces, after the running water of supply ormal weight (on a small quantity), cooling water electromagnetic valve 4e is disconnected and stops the supply of running water, the temperature of pipe portion 54a rises to set point of temperature once again thus.Thus, supply running water off and on, the temperature recovering pipe portion 54a supplies running water, makes the flow path surfaces temperature of pipe portion 54a maintain more than the temperature range of steam ST generation, thus produces steam ST off and on.
In addition, when producing hot water HW in heating unit 5, supplying water after making heating unit 5 sky burn, or after water supply start, make heating unit 5 be energized, thus the temperature of the flow path surfaces of pipe portion 54a being controlled the temperature for not producing steam.Such as, ON/OFF control and continuous water supply are carried out to cooling water electromagnetic valve 4e, produce the hot water (hot water HW) that can not become steam ST thus.
The steam ST produced by heating unit 5 is pushed out to heat-resistant hose 58 side under the effect of the steam pressure produced at that time.In addition, the hot water HW produced by heating unit 5 is pushed out to heat-resistant hose 58 side under the effect of the pressure of supply water (hydraulic pressure) from cooling water electromagnetic valve 4e.Thus, no matter the pipe portion 54a of supply running water is when producing steam ST, or when producing hot water HW, all use as public stream.
Figure 12 is the side cutaway view of the spray regime schematically showing steam/heat water.In addition, in fig. 12, for convenience of description, overlap illustrates hot gas and the hot water HW of steam ST change, in fact, and any person in clothing supply hot gas and hot water HW.
As shown in figure 12, the direction setting of nozzle 59 is towards bight (position bottom) P of the bottom side as the main board 2c of cylinder 2 and the border of base plate 2d.And, the steam ST produced by heating unit 5 temperature before being sprayed from nozzle 59 by heat-resistant hose 58 is reduced, thus become hot gas (water droplet of high temperature, liquid state) from steam ST (gaseous state), hot gas (liquid state) is sprayed to clothing, and non-steam (gaseous state).On the other hand, the hot water HW produced by heating unit 5, by spraying from nozzle 59 after heat-resistant hose 58, is ejected into washings (clothing) with the state of hot water HW (liquid state).
