Steam generator 420 penetrates water to make its flash evaporation to by the wall heated, and therefore, the heater under water with utilization produces compared with the conventional art of steam, and the power consumption produced needed for identical quantity of steam is few.

< water supply mechanism >

Figure 13 is the skeleton diagram of water supply mechanism 500.Use Figure 13 that water supply mechanism 500 is described.

The water supply mechanism 500 that cavity space 430 to steam generator 420 penetrates water comprises above-mentioned the first feed water valve 310, aqua storage tank 320, pump 330 and tube connector 421.Water supply mechanism 500 also possesses the level sensor 321 of the water level for measuring the water that aqua storage tank 320 stores.The water level that first feed water valve 310 also can detect according to level sensor 321 supplies water to aqua storage tank 320 or stops supplying water to aqua storage tank 320.

Also the first feed water valve 310 can be controlled according to the working time of pump 330 and/or pattern (the water supply action of interval and/or continuous print water supply action).Such as, be adjusted to the aqua storage tank 320 when the release of pump 330 from the output of the first feed water valve 310 and become empty.Its result, is difficult to freezing of the water in aqua storage tank 320 occurs.

The water be stored in aqua storage tank 320 is supplied to cavity space 430 by tube connector 421 by pump 330.The water supply action of the interval of pump 330 is adjusted to the water flash evaporation making injection in cavity space 430.

The result of the water evaporation in cavity space 430, the impurity contained in water is also piled up sometimes in cavity space 430.The continuous print water supply action of pump 330 is adjusted to and makes water flow into cavity space 430 with the flow velocity enough washing away piled up impurity.

Blast pipe 422 is connected to steam conduction pipe 340.The steam produced in cavity space 430 by the water supply action of the interval of pump 330 and flow into accepting groove 200 by blast pipe 422 and steam conduction pipe 340 by the water that the continuous print water supply action of pump 330 flows in cavity space 430.

The steam of < to accepting groove and the supply > of water

Figure 14 is the summary rearview of the front portion 222 of accepting groove 200.Fig. 1, Figure 13 and Figure 14 is used to illustrate to the steam of accepting groove 200 and the supply of water.

As shown in Figure 1, the annulus 224 of anterior 222 comprises and swing roller 210 inner face 225 in opposite directions and antetheca 111 outside 226 in opposite directions with casing 110.Figure 14 mainly represents inner face 225.

Steam organization of supply 300 possesses the branched pipe 351 and nozzle 352 that are installed on inner face 225.Steam organization of supply 300 also possesses the steam pipe 353 be connected with nozzle 352 by branched pipe 351.Steam conduction pipe 340 is connected to branched pipe 351 via surrounding wall portion 223.

The steam produced in cavity space 430 increases along with the pressure in cavity space 430, flows into steam conduction pipe 340 by blast pipe 422.Afterwards, steam arrives branched pipe 351 from steam conduction pipe 340.Nozzle 352 is arranged at the position more closer to the top than branched pipe 351.The steam arriving branched pipe 351 is high temperature, therefore, is directed into steam pipe 353 and arrives nozzle 352.Finally, steam sprays downwards from nozzle 352.Its result, steam directly blows to by the opening portion 213 of swing roller 210 clothing be housed in accepting groove 200.In the present embodiment, the steam produced in cavity space 430 guides to nozzle 352 by blast pipe 422, steam conduction pipe 340, branched pipe 351 and steam pipe 353.

As mentioned above, the pump 330 carrying out the water supply action of interval penetrates appropriate water to the cavity space 430 of high temperature, therefore, and water flash evaporation.Its result, the interior pressure of cavity space 430 sharply increases.Therefore, the inner space crosscut of accepting groove 200 with high-pressure injection, is upper and lower from nozzle 352 by steam.At the lower end of swing roller 210, due to gravity, clothing is easily concentrated.From the lower end of the steam arrival swing roller 210 that the nozzle 352 on the top being installed on accepting groove 200 sprays, therefore, be supplied to clothing to high-efficiency steam rate.

Branched pipe 351 possess be connected to steam conduction pipe 340 female pipe 354, from the bending upward upper sub-pipe 355 of female pipe 354 and from the bending downwards lower sub-pipe 356 of female pipe 354.Steam or water is flowed into by steam conduction pipe 340 in female pipe 354.Upper sub-pipe 355 is connected to steam pipe 353, and regulation steam is towards the path upwards of nozzle 352.

Lower sub-pipe 356 is different from upper sub-pipe 355, specifies downward path.During pump 330 carries out continuous print water supply action, the water being flowed into branched pipe 351 by steam conduction pipe 340 is flowed down by lower sub-pipe 356 due to Action of Gravity Field.

Angle theta 1 shown in Figure 14 between female pipe 354 and upper sub-pipe 355.In addition, Figure 14 also illustrates the angle theta 2 between female pipe 354 and lower sub-pipe 356.Angle theta 1 is obtuse angle, and on the other hand, angle theta 2 is acute angles.Because angle theta 2 is acute angles, therefore, larger from the flow losses of the downward sub-pipe 356 of female pipe 354.Therefore, the steam flowing into female pipe 354 flows to lower sub-pipe 356 hardly, flows mostly to sub-pipe 355.On the other hand, upper sub-pipe 355 specifies flow path upwards, and therefore, the water flowing into female pipe 354 flows to upper sub-pipe 355 hardly due to the effect of gravity, flow mostly to lower sub-pipe 356.Therefore, the flow path of steam is suitably separated with the flow path of water.

The action > of the pump of < interval

Figure 15 is the figure of the relation roughly represented between the temperature in the intermitten of pump 330 and cavity space 430.Use Figure 10, Figure 13 and Figure 15 that the intermitten of pump 330 is described.

As shown in figure 15, during pump 330 work, (run duration) is set to shorter than (between withholding period) during pump 330 stopping.Its result, appropriate water is penetrated in cavity space 430.

At run duration, supply the water of specified amount to cavity space 430.Its result, water evaporates and becomes steam.Due to from water to the heat of gasification caused by the phase change of steam, the temperature of cavity space 430 temporarily reduces.As mentioned above, set long between withholding period, therefore, heater 425 can make cavity space 430 enough heat up between withholding period.Thus, during pump 330 carries out intermitten, the steam of high pressure continues to be supplied to accepting groove 200.Particularly between withholding period, cavity space 430 enough heats up, at run duration, the appropriate water of the heat energy supply flash evaporation had the steam generator 420 comprising cavity space 430 (such as about 2cc/ time), thus continue to accepting groove 200 steam supplying high pressure well.

In step S110, control part 122 opens the second feed water valve 142 and/or the 3rd feed water valve 143, supplies water to accepting groove 200.Afterwards, step S120 is performed.

(step S120)

Control part 122 prestores the information of the threshold value " LTH " about specifying for the water level of the washings in accepting groove 200.In step S120, control part 122 uses the detection signal exported from water level detecting portion 162, compares water level and the threshold value " LTH " of the washings in accepting groove 200.If the water level of washings exceedes threshold value " LTH ", then perform step S130.Perform step S110 in other cases.In addition, threshold value " LTH " is suitably defined as, if the water level of washings exceedes threshold value " LTH ", then warm water heater 160 is dipped in washings.In the present embodiment, be exemplified as the water level of specifying with the water level that threshold value " LTH " represents.

(step S130)

In step S130, control part 122 allows warm water heater 160 work.Its result, washings are promptly heated.If the heating of washings starts, then perform step S140.

(step S140)

Control part 122 prestores the information of the first threshold temperature " TTH " about the temperature specifications for the washings in accepting groove 200.In step S140, control part 122 uses the detection signal exported from water temperature test section 161, compares water temperature and the first threshold temperature " TTH " of the washings in accepting groove 200.If the water temperature of washings exceedes first threshold temperature " TTH ", then perform step S150.Perform step S130 in other cases.In the present embodiment, be exemplified as the water temperature of specifying by the water temperature that first threshold temperature " TTH " represents.
