The washings that transported by circulating pump 20 flow into water guide path 55b via the discharge side path 16b of circulating path 16 from connecting portion 51.The washings that flow into water guide path 55b from outlet 55d towards the inner surface of the front side wall 3h of tank 3 and and the relative face of inner surface of front side wall 3h be to discharge between the outer surface of front side wall 4b of swing roller 4.Shown in Fig. 5 A, the washings that are discharged from via outlet 55d from water guide path 55b spray to the inboard of swing roller 4 through the ejiction opening 53 of stream 52 from ring-type.In addition, be provided with a plurality of outlet 55d with the mode relative along the direction of rotation of swing roller 4 with the ejiction opening of ring-type 53.Utilize said structure, washings can be efficiently to the bigger scope ejection of the inboard of swing roller 4.That is, no matter what of the amount of washings, washings all can be supplied with efficiently.
At this, the front side wall 3h of tank 3 has inclined plane 3ha and the guide surface 56 that links to each other with inclined plane 3ha from the position corresponding to outlet 55d.3ha's washings that are discharged to stream 52 from outlet 55d flows along guide surface 56 from the inclined plane.Thus, washings spray towards the inside of swing roller 4 shown in the arrow A of Fig. 5 A via cylinder opening 54 from ejiction opening 53.Because washings arrive the inside of swing roller 4, therefore, washings can be supplied with to washings more efficiently.
And, shown in Fig. 5 B, through the angle of inclination guide surface 57 different with the angle of inclination of guide surface 56 is set, can be with different angle ejection washings.For example; Will be from branch the angle of inclination of looking with the corresponding guide surface 56 of outlet 55d (right side Fig. 3 B) in left side, the front of water guide path 55b be made as a (with reference to Fig. 5 A); In addition, the angle of inclination that will look from the front of water guide path 55b with the corresponding guide surface 57 of outlet 55d (left side Fig. 3 B) on right side is made as b (with reference to Fig. 5 B).At this, form guide surface 56 and guide surface 57 with the mode of angle of inclination a＞b.
Fig. 6 is the key diagram of ejection state of washings of the tumbling-box washing machine of this embodiment of expression.Look from the front of tumbling-box washing machine 1, spray to the top from the washings of the ejiction opening in the left side 53 ejections washings of the ejection of the direction shown in the arrow A Fig. 5 A (promptly to) are such shown in the spray shape S1 of Fig. 6.On the other hand, look, from the washings of the ejiction opening 53 on the right side washings of the ejection of the direction shown in the arrow B among Fig. 5 B (promptly to) such below ejection shown in the spray shape S2 of Fig. 6 to spray shape S1 from the front of tumbling-box washing machine 1.That is the washings of, discharging from each outlet 55d flow along the angle that inclines towards each other different guide surface 56 or guide surface 57.Afterwards, washings spray via the inside of cylinder opening 54 to swing roller 4 from ejiction opening 53, and therefore, it sprays as the ejection different washings of angle.
In addition, the angle of inclination of guide surface 56 or guide surface 57 exerts an influence to the disperse state of the washings after the ejection.Under the less situation in angle of inclination (promptly being the situation of the guide surface 57 of b in this embodiment medium dip angle), the mobile washings of coming of 3ha change angle sharp because of guide surface 57 along the inclined plane.In other words, washings are in the state that strikes against guide surface 57.Under this state, washings spread along guide surface 57 and because of bump.On the other hand, under the bigger situation in angle of inclination (promptly being the situation of the guide surface 56 of a in this embodiment medium dip angle), the mobile washings of coming of 3ha directly flow along guide surface 56 along the inclined plane, and ejection less diffusely.That is, as shown in Figure 6, the spray shape S2 of the washings that the ejiction opening 53 on less right side sprays from the angle of inclination compares with the spray shape S1 of the washings of ejiction opening 53 ejections in the left side bigger from the angle of inclination, has the shape of diffusion.That is, from about the washings of ejiction opening 53 ejection have different diffusion angles.For example, be under the situation below about 120 degree at the angle of inclination, washings spread ejection significantly, and the angle of inclination be 130 spend about more than situation under, washings spread lessly and are membranaceously and spray.Like above-mentioned ground, with different ejection angle ejection washings, and, with different disperse state ejection washings, thus, can be suitable for respectively spraying washings to the more situation ground of the amount of washings from the less situation of the amount of washings.
At this, after just beginning cleaning, washings does not contain washings, and is in the bigger fluffy state of volume.For example, under the situation of ejiction opening 53 washings in left side shown in Figure 6 sealing, washings from the ejiction opening 53 on right side to swing roller 4 ejections.Owing to make washings spread to such an extent that spray significantly from the ejiction opening 53 on right side, therefore, can quickly near the washings the ejiction opening 53 in left side be soaked.The washings smaller volume that contains washings thus, can be removed the sealing to the ejiction opening 53 in left side.
On the other hand, the washings that spray owing to the ejiction opening 53 from the right side spread greatlyyer, therefore, are difficult to arrive the inside of swing roller 4., spread lessly from the washings of the ejiction opening in left side 53 ejections, it arrives the inside of swing roller 4 towards the center of swing roller 4.Thus, can be quickly the washings of the inside that is positioned at swing roller 4 be soaked.Through soaking washings quickly, the washings in the swing roller 4 can become in advance and be easy to activity, can improve thereby beat the effect of washing.In addition, through soaking washings quickly, the volume of washings can diminish quickly.Thus, can produce the space between washings and the washings, therefore, washings can spray to washings efficiently.That is, washings can be supplied with to washings efficiently.
At this, the emission direction of ejiction opening 53 is that washings can dissimilate according to the shape of ejiction opening 53 with respect to the emission direction for the vertical line at cylinder opening 54 centers.For example; Emission direction through the ejiction opening about making 53 be 0 degree through the angle that becomes between the vertical line at cylinder opening 54 centers; That is, make emission direction parallel with above-mentioned vertical line, washings can be easy to arrive the inside of swing roller 4 through the space between washings and the washings.In addition; The ejiction opening 53 that makes the right side is the emission direction of the washings ejiction opening 53 that spreads greatlyyer a side with the angle that becomes between the above-mentioned vertical line is 35 degree～45 degree; And; The ejiction opening 53 that makes the left side is the emission direction of the washings ejiction opening 53 that spreads lessly a side with the angle that becomes between the above-mentioned vertical line is that 50 degree～60 are spent, thus, and the washings that can suppress to spray collision each other.Through suppressing washings collision each other, can reduce the loss when supplying with washings.Thus, can soak washings efficiently, the cleaning efficiency of tumbling-box washing machine 1 can improve.
As stated, no matter be under the more situation of the amount of washings or under the less situation of the amount of washings, washings all can be supplied with efficiently, thereby can soak washings efficiently.Through soaking washings efficiently, can obtain water-saving result.In addition, outlet 55d be located at not with swing roller 4 in the washings position contacting on.Therefore, washings can not hang on the outlet 55d, thereby can not clean, produce when rinsing, oven dry obstacle.In addition, washings can not damage yet, and can not be torn yet.In addition, under the situation of the positive and negative continuous rotation drive pattern of operation, change the upper-lower position of washings, and under the situation of the positive and negative partial rotation drive pattern of operation, change the position, the left and right sides of washings, thus, the effect of the ejection of washings can increase.In addition, though the situation at two places is illustrated about in this embodiment for ejiction opening 55d being, even be the situation more than 3 places at ejiction opening 55d, also embodiment of the present invention likewise.
