In addition, use the auxiliary bracket 810 be fastened on the body 100 to alleviate vibration and noise that in drying (spinning) operating process, on body, produces and the intensity of strengthening body 100.

As shown in Figure 3, the water treatment facilities 900 of handling the water that is infeeded steam generator 600 can be arranged in the water inlet pipe 620.

At this, in water treatment facilities, the implication of processing can be all physics and the chemical property that changes water.In other words, water treatment facilities can refer to a kind of water be handled to improve detersive efficiency or to improve the equipment of steam generator performance.

Yet, because being a kind of processing, water treatment facilities of the present invention infeeded the mechanism of the water of steam generator 600, preferably water is handled to prevent producing incrustation scale in steam generator.

Therefore, if more specifically describe, water treatment facilities 900 can be a kind of water-softening plant or filter.So in the embodiments of the present invention, water-softening plant and filter are by Reference numeral 900 expressions.

As shown in Figure 3, water softening plant 900 is set in the water supply pipe 620 in the water inlet passage 621 that is included in steam generator 600, and will flow in water in the water supply pipe 621 and become soft water and flow into space 611 with the water that soft water is infeeded steam generator 600.

Simultaneously, shown in Figure 4 and 5, water softening plant 900 comprises housing 910, and this housing has space 913, and it is used for because the internal material of demineralized water makes introducing water softening wherein.Described internal material can be all kinds, for example, comprises ion exchange resin and the internal material that is used for the salting liquid of recirculation.

Here, inlet 911 is formed on and makes water supply pipe 621 be connected in the top part of the housing 910 at this place, so that introduce water, is used to discharge the water that is softened and export the 912 bottom parts that are formed on housing 910.

In addition, be formed with opening 914, be used for putting into ion exchange resin and at the salting liquid of the space of housing 901 913 recirculation, opening is by accessory cover 920 On/Off in a side of the top of housing part.

From hard water for example, remove hard component by water-softening plant 900 as calcium and magnesium and all kinds of impurity and so on by running water of outside supply and so on.From here the water that is softened is offered water and flow into space 611, producing in the process of steam by heater 640 like this, can prevent that the interior perimeter surface that flows into space 611 at water from producing incrustation scale.

That is to say, under hard water flows that contains hard component and impurity and heated situation, can prevent that the interior perimeter surface that flows into space 611 at water from producing incrustation scale, or prevent from flowing into the exit passageway 630 generation incrustation scales that space 611 is communicated with water.

Produce incrustation scale if flow into the interior perimeter surface in space 611 at water, can not by heater heat be passed to water reposefully and flow into space 611.If produce incrustation scales at exit passageway 630, exit passageway 630 is blocked, and can not supply with steam swimmingly.

Therefore, owing to will infeed steam generator 600, can prevent the problems referred to above by the softening water of water treatment facilities.

Though do not describe, can the structural change of water softening plant 900 is become various forms.

More particularly, though the salting liquid that water softening plant 900 can make spent ion exchange resin and be used for recirculation carries out ion conversion (ion-change), also can use and remove the energy filter (energy filter) that is included in the water and maybe can play the far red light radiation ceramic filter of antibacterial action with demineralized water as the metal ion component of heavy metal and so on.

At that time, preferably, will be respectively charged in the housing as the internal material of filter and so on and make water by as described in housing so that water is softened cleanlyer.

As shown in Figure 7, water softening plant 900 can be arranged between outside water supply pipe 20 and the feed water valve 200, be used for the softening water that will infeed steam generator 600.

The water softening by water-softening plant is infeeded the steam generator 600 that is connected with feed water valve 200, and also flows into the drawer that is used for washing agent/fabric softener 700 that is connected with feed water valve 200.

Fig. 9 and 10 shows the filter plant 900 that is provided as the example that is used for filtered water of water-softening plant, and different with above-mentioned water-softening plant embodiment, it is filter rather than water-softening plant.

As shown in figure 10, the filter 900 that is used to filter the water of planning to infeed steam generator 600 is net formula porous filters, it can be arranged on the water inlet pipe 620, so that the pipeline that connects feed water valve 200 and steam generator 600 to be provided.

That is to say, filter 900 can be arranged in the water supply pipe 621 in the water inlet passage 620 that is included in steam generator 600, and bag filter is contained in the foreign substance in the water that flows that water flows into space 611, and the clean water that will not contain foreign substance infeeds the water of steam generator 600 and flows in the space 611.

Flow in the space 611 owing to clean water is infeeded the water of steam generator 600, can prevent from the process of utilizing heater generation steam, to flow into the interior perimeter surface generation incrustation scale in space 611 at water.

If the water that contains foreign substance flows into space 611 at water and is heated, not only flow in the space 611 but also may form incrustation scale calciferous flowing in the exit passageway 630 that space 611 is connected with water at water.

And, since less from steam generator to the passage cross section of bucket supply steam, should prevent that incrustation scale from not stopping up described passage.

Produce incrustation scale if flow into the interior perimeter surface in space 611 at water, heater can not be delivered to heat water and flow into space 611, and if produce incrustation scale at exit passageway 630, just can not supply steam swimmingly.

In view of the above, the clean water that has been reduced foreign substance by filter 900 can be infeeded steam generator 600, avoid described problem with this.
