Fig. 3 is the vertical profile front view of foam water generation device 11.As shown in the figure, the bottom of back box 12a becomes peristome 13a, and sidepiece and top are surrounded by perisporium 14a.In addition, the groove bar (recess) 15 with the chimeric usefulness of front cabinet 12b is provided with along perisporium 14a.In addition, the part of either party sidepiece of the left and right sides (being the right side in Fig. 1) is outstanding, formation cylindrical portion 16, and flexible pipe 10 is connected (with reference to Fig. 2) at this place.

In the drawings, the 17th, expression and the groove that is installed in the filter 22 chimeric usefulness on the

front cabinet

12b, 23a/23b are the filter of expression with shape, 18a/18b is the pawl (for filter 23a/23b being fixed on the projection on the assigned position) that expression filter 23a/23b uses.In addition, the position of the filter 23a that is fixed by pawl 18a is than position (the concrete just width of otch 24) right shift a little of the filter 23b that is fixed by pawl 18b, pawl 18a than pawl 18b a little to the right (inboard of foam water generation device 11) outstanding.

On the one hand, the bottom of front cabinet 12b also becomes peristome 13a, and sidepiece and top are surrounded by perisporium 14b.In addition, the prominent bar (protuberance) 19 with the chimeric usefulness of back box 12a is provided with along perisporium 14b.In addition, outstanding, the formation cylindrical portion 16 of a part of either party sidepiece of the left and right sides (being the left side in Fig. 1), flexible pipe 10 is connected (with reference to Fig. 2) at this place.

In the drawings, 22 expression filters, 20 expressions and the groove that is installed in the chimeric usefulness of filter 23a/23b on the back box 12a, the pawl that 21 expression filter 23a/23b use.A pair of pawl 21 be configured in groove 20 on the angle point.

If as shown in Figure 3 that back box 12a and front cabinet 12b is chimeric, the filter 22 that then is installed on the front cabinet 12b embeds in the groove 17 of back box 12a, and the filter 23a/23b that is installed on the back box 12a embeds in the groove 20 of front cabinet 12b.Fig. 4 is the vertical profile side view of foam water generation device 11, the chimerism of expression back box 12a and front cabinet 12b.In addition, in the bottom of box 12, peristome 13a and peristome 13b are chimeric, the rectangular peristome 13 of formation.Fig. 5 is the upward view of foam water generation device 11, and expression is seen box 12 from peristome 13 sides.

And, in box 12, be provided with two kinds of filters shown in Fig. 6 (a) and Fig. 6 (b).

The structure of Fig. 6 (a) expression filter 22.As shown in the figure, filter 22 is the filters that are provided with the mesh shape of many apertures.This filter 22 also is to be made by synthetic resin such as plastics.

In addition, the structure of Fig. 6 (b) expression filter 23a/23b.Filter 23a/23b is the filter of incision-like, is at housing inboard interlaced many otch (peristome) 24 and lattice bar (non-peristome) 25 to be set and to form.

After being installed in the box 12 as filter 23a/23b the filter shown in two Fig. 6 (b) respectively, as mentioned above, owing to stagger a little in its position, therefore, as shown in Figure 7, the lattice bar 25 of filter 23a overlaps respectively with the lattice bar 25 of filter 23b with the otch 24 of filter 23b, the otch 24 of filter 23a.

Its result, the water of supplying with from flexible pipe 10 collides any one lattice bar 25 the filter 23a/23b, and containing from otch 26 inhaled airs becomes foam-like (in addition, the cross section of foam water is that rectangle, vertical section are oval-shaped band shapes).In addition, because the thickness of lattice bar 25 is than the thin thickness of housing, therefore, gap between the lattice bar 25 of the otch 24 of water by filter 23a, filter 23a and the lattice bar 25 of filter 23b and the otch 24 of filter 23b, arrival peristome 13.

Because the water of discharging from peristome 13 is foam-like, can not disperse even therefore run into the washings that washtub holds concurrently in the dehydration barrel 3, at a high speed and soak into to washings equably yet, therefore, compare with existing washing machine, the outward appearance volume of water increases, and can reduce the use amount of water.And the sound when supplying water also reduces.

Fig. 8 is the curve map of relation of the amount of dispersing of the water of the every kind method of supplying water of expression washtub when holding concurrently the rotating speed of dehydration barrel 3 and each rotating speed.As washing machine of the present invention, supply with under the situation of foam water, the rotating speed of dehydration barrel 3 increases even washtub is held concurrently, and also the amount of dispersing of water can be suppressed to seldom.

Fig. 9 is the curve map of every kind of method of supplying water of expression to the leaching requirement of washings.Compare with the situation of existing water supply as can be seen, when supplying with foam water, water absorption increases about 30%.

And owing to also supply with foamed water to washing powder, therefore, more washing powder dissolves quickly.Its result can reduce the use amount of washing powder, can improve the washability of washing machine.Figure 10 is the solubility table of the washing powder of every kind of method of supplying water of expression.Compare with the situation of existing water supply as can be seen, the solubility of washing powder improves when supplying with foam water.In addition,,, therefore do not need in washing powder box, to supply water, can prevent the mouldy or dirt of washing powder box because foam water can fully be dissolved washing powder even in washtub is held concurrently dehydration barrel 3, directly pour under the situation of washing powder.

In addition, the water supply of the foam water in the rinsing process can be carried out (be interrupted and supply water) by phased manner.For example, as shown in figure 11, supply with one minute foam water, stop to resupply 30 seconds foam water after 30 seconds.By the dwell time of water supply is set like this, the water washings of being supplied with by before water supply sucks equably, and therefore the efficient with respect to the rinsing of output further improves, and water-saving result also increases.In addition, this interruption supplies water and is not limited to foam water, also can implement in existing water supply.
