Blast pipe 422 is connected with steam conduction pipe 340.By the intermittent water supply of pump 330, move at the steam of cavity space 430 interior generations and pass through blast pipe 422 and steam conduction pipe 340 inflow accepting grooves 200 by the water in the continuous water supply action inflow cavity space 430 of pump 330.

Figure 12 is the rearview of summary of the front portion 222 of accepting groove 200.With reference to Fig. 1, Figure 11 and Figure 12, illustrate that steaming G&W is to the supply of accepting groove 200.

As shown in Figure 1, anterior 222 annulus 224 comprise with the opposed inner face 225 of swing roller 210 and with the opposed outside 226 of antetheca 111 of framework 110.Figure 12 mainly illustrates inner face 225.

Steam supply mechanism 300 possesses bifurcated pipe 351 and the nozzle 352 that is installed on inner face 225.Steam supply mechanism 300 also possesses the steam pipe 353 that connects bifurcated pipe 351 and nozzle 352.Steam conduction pipe 340 is connected with bifurcated pipe 351 by surrounding wall portion 223.

Steam in cavity space 430 interior generations flows into steam conduction pipes 340 along with the pressure in cavity space 430 increases and passes through blast pipe 422.Afterwards, steam arrives bifurcated pipe 351 from steam conduction pipe 340.Nozzle 352 is provided in the position that is positioned at top than bifurcated pipe 351.The steam that arrives the high temperature of bifurcated pipe 351 is directed into steam pipe 353, arrives nozzle 352.Finally, steam sprays downwards from nozzle 352.In the present embodiment, blast pipe 422, steam conduction pipe 340, bifurcated pipe 351 and steam pipe 353 guide to nozzle 352 by the steam in cavity space 430 interior generations.Thereby blast pipe 422, steam conduction pipe 340, bifurcated pipe 351 and steam pipe 353 are exemplified as guiding tube.

As mentioned above, carry out the pump 330 of intermittent water supply action to the appropriate water of cavity space 430 ejaculation of high temperature, so water flash evaporation.Its result, the interior pressure of cavity space 430 sharply increases.Thereby, steam from nozzle 352 with high-pressure injection, the inner space of upper and lower crosscut accepting groove 200.Clothing easily concentrates near the lower end of swing roller 210 due to gravity.Owing to arriving near the lower end of swing roller 210 from being installed on steam that the nozzle 352 on the top of accepting groove 200 sprays, so steam is provided to clothing efficiently.

Bifurcated pipe 351 possess the mother who is connected with steam conduction pipe 340 manage 354, from mother manage 354 crooked upward son pipe 355 and from mother manage 354 crooked downwards son pipe 356.Steam or water flow into female pipe 354 by steam conduction pipe 340.Upper son pipe 355 is connected with steam pipe 353, and regulation steam is towards the path making progress of nozzle 352.The path making progress of being stipulated by upper son pipe 355 and steam pipe 353 in the present embodiment, is as the first path illustration.Female pipe 354 is as inflow pipe illustration.Upper son pipe 355 is as the first pipe illustration.

Lower son pipe 356 is different from upper son pipe 355, stipulates downward path.Pump 330 carry out continuous water supply action during, the water that flows into bifurcated pipes 351 by steam conduction pipe 340 manages 356 to dirty because Action of Gravity Field pass through lower son.The downward path of being stipulated by lower son pipe 356 in the present embodiment, is as the second path illustration.Lower son pipe 356 is as the second pipe illustration.

Figure 12 illustrates the angle theta 1 between female pipe 354 and upper son pipe 355.And Figure 12 also illustrates the angle theta 2 between female pipe 354 and lower son pipe 356.Angle theta 1 is obtuse angle, and angle theta 2 is acute angle.Therefore because angle theta 2 is acute angle, the flow losses of son pipe 356 are larger downwards from mother, to manage 354.Thereby the steam that flows into female pipe 354 can flow to lower son pipe 356 hardly, and Main Current pipe 355 upwards.On the other hand, due to upper son pipe 355 regulations flow path upwards, the water that therefore flows into female pipe 354 can flow to upper son pipe 355 hardly due to the effect of gravity, and Main Current is son pipe 356 downwards.Thereby, the flow path of steam with the flow path of water by suitably separated.

The action of<pump intermittently>

Figure 13 is the diagram that roughly represents the intermitten of pump 330 and the relation of the temperature in cavity space 430.The intermitten of pump 330 is described with reference to Fig. 8, Figure 11 and Figure 13.

As shown in figure 13, pump 330 move during (during ON) be set to than pump 330, stop during (during OFF) short.Its result, appropriate water is fired in cavity space 430.

During ON, to the water of cavity space 430 supply ormal weights.Its result, water evaporation and become steam.Due to the heat of gasification that the phase transformation because of from water to steam causes, the temperature of cavity space 430 temporarily reduces.As mentioned above, during OFF, be set longly, so heater 425 can make cavity space 430 heat up fully in during OFF.Thereby, pump 330 carry out intermitten during, the steam of high pressure continues to be supplied to accepting groove 200.Especially, during OFF, inner cavity chamber space 430 is warmed fully, during ON, the appropriate water of the heat energy flash evaporation that supply has with respect to the steam generator 420 that comprises cavity space 430 (for example, about 2cc/ time), therefore, to accepting groove 200, continue well the steam of supply high pressure.

The utilization of the steam in<washing procedure>

Figure 14 is the diagram of variation that is roughly illustrated in the temperature of the water that is supplied to tank 220 in washing procedure.The effect of the steam using in washing procedure with reference to Fig. 1, Fig. 8, Figure 11 and Figure 14 explanation.
