In addition, the opening direction of water inlet 51, ejiction opening 55d and jet 53 is towards the roughly pivot side (the arrow labeled direction of Fig. 3 B) of swing roller 4.In addition, from the ejiction opening 55d of 51 to 2 positions of water inlet of 1 position, be communicated with by the water guide road 55b that is closed respectively.Therefore, particularly for for water inlet 51 ejiction opening 55d far away, utilize the interior shape of water guide road 55b to suppress the reduction of water flow pressure from water inlet 51 to ejiction opening 55d of washings.
Like this, water circulation system 16 is provided with water inlet 51, water guide road 55b, a plurality of ejiction opening 55d and a plurality of jet 53.At this, water inlet 51 is located at the periphery wall of tank 3, is connected with ejection side path 16b from circulating pump 20.Water guide road 55b is located at the front bulkhead 3h of tank 3, links with water inlet 51, and makes the washings shunting.A plurality of ejiction opening 55d are located at water guide road 55b, between the front bulkhead 4b front of the front bulkhead 3h back side of tank 3 and swing roller 4, spray washings.In swing roller 4, spray from a plurality of jets 53 from the washings of a plurality of ejiction opening 55d ejections.
In addition, a plurality of ejiction opening 55d between the front bulkhead 4b front of the front bulkhead 3h back side of tank 3 and swing roller 4 at the circumferential scope inner opening of regulation.And the front bulkhead 3h back side of tank 3 has to be made from the washings of a plurality of ejiction opening 55d ejection guide surface 56 towards the internal flow of swing roller 4.And, mobile from the washings of a plurality of ejiction opening 55d ejections along the back side and the guide surface 56 of the front bulkhead 3h of tank 3, spray from a plurality of jets 53.And the opening direction of water inlet 51, a plurality of ejiction opening 55d and a plurality of jet 53 is towards the pivot side of swing roller 4.Through above-mentioned structure, the tumbling-box washing machine of embodiment 1 of the present invention can suppress the water flow pressure loss from water inlet 51 to ejiction opening 55d of washings.Therefore, even the very little water yield also can be sprayed the washings of high water flow pressure from two jets 53, all can spray more powerful washings to the washings of small size and big volume.Its result is because the drum type washing function of embodiment of the present invention 1 improves the accessibility of washings to washings, so can improve clean result.
In addition, Fig. 5 is the front view of state of the tumbling-box washing machine jet cleaning water of expression embodiment 1 of the present invention.Washings when beginning to wash is when the state lower volume that does not contain washings is big; Even under near the situation about circumferentially stopping up by the washings edge jet in left side shown in Figure 5 53, also can spray towards the 1st opening 54 of swing roller 4 neighbouringly from the jet 53 on right side.Then, near the washings the promptly wetting jet 53, volume reduces, thereby can be by solving because near the obstruction the jet 53 in the left side that washings causes.
In addition, no matter what of the washings in the tumbling-box washing machine swing roller of embodiment of the present invention 14 can both make washings play a role effectively.In addition, because ejiction opening 55d is positioned at not the washings position contacting with swing roller 4, so can prevent to hang washings and influence necessary action such as washing, rinsing, drying or prevent damage, stave washings because of colluding.Improve the jeting effect of washings through the action that is combined in the action of changing washings up and down and the left-right reversed washings when the positive and negative arc rotating drive pattern in the positive and negative continuous rotation drive pattern.
In addition; The shape of number, change and the ejiction opening 55d corresponding jet 53 of the tumbling-box washing machine of embodiment 1 of the present invention through increasing ejiction opening 55d can make washings different with respect to the start point of the spray angle of the rotating shaft 10 of swing roller 4 and injection.
So, little from a side jet 53 towards the spreading width of rotating shaft 10 directions of swing roller 4, carry out injection towards the interior side direction of swing roller 4.In addition, have the injection of big spreading width from the opposing party's jet 53, the washings that is difficult near the inside part the center of wetting swing roller 4 is also promptly wetted, improves clean result.In addition, reduce the volume of this washings through the washings that makes washings infiltrate near the inside part the center of swing roller 4, the washings swing roller 4 in moves easily in advance.Therefore, also can improve and beat the effect of washing, and clean result can further be improved to washings integral spray washings in the gap that can reduce to form through the volume owing to washings.
In addition, in this embodiment 1, about 2 positions have ejiction opening 55d, yet also can have ejiction opening more than the position at 3.
(embodiment 2)
Fig. 6 is the rearview of antetheca of tank of seeing the tumbling-box washing machine of embodiment 2 of the present invention from the rotating shaft direction of swing roller.In embodiment 2 of the present invention, to marking identical Reference numeral, omit its explanation with embodiment 1 identical inscape, different points is described.
As shown in Figure 6, in the plane vertical with rotating shaft 10 directions of swing roller 4, linking the pivot of swing roller 4 and the line of water inlet 51 is the 1st line 61.Then, the both sides of the 1st line 61 in this plane are provided with apart from the different a plurality of ejiction opening 55d of water inlet 51 distances.Link the pivot of swing roller 4 and be the 2nd line 62, link the pivot of swing roller 4 and be the 3rd line 63 apart from the line of the ejiction opening 55d of water inlet 51 distance apart from the line of the near ejiction opening 55d of water inlet 51 distances.In addition, angle [alpha] is the 1st line 61 and the 2nd line 62 angulations, and angle beta is the 1st line 61 and the 3rd line 63 angulations.And it is the 4th line 64 that the plumb line that will pass through the pivot of swing roller 4 projects to the line that forms on the plane vertical with rotating shaft 10 directions of swing roller 4.
With respect to this, under the situation of angle [alpha]＜angle beta, comparing with the situation of angle [alpha]=angle beta from the injection of the washings of the jet of angle [alpha] side 53 ejections becomes bigger water flow pressure.On the contrary, compare with the situation of angle [alpha]=angle beta from the injection of the washings of the jet of angle beta side 53 ejections and become less water flow pressure.
The tumbling-box washing machine of embodiment of the present invention 2 like this is angle [alpha]＜angle beta.According to above-mentioned structure, as shown in Figure 5, it seems from the front washings from the jet 53 in left side as spray flow shape A towards direction haply, and spray with the angle of spreading width with straight wire.It seems washings from the jet 53 on right side from the front as spray flow shape B,, and spray with fan shape with spreading width wideer than spray flow shape A towards the lower direction of spray flow shape A.
That is, the washings that spray from separately ejiction opening 55d have different water flow pressure, from about jet 53 spray in swing roller 4 via the 1st opening 54 of Fig. 1.Therefore, can realize the different different injection of injection, jet width and start point of spray angle with respect to the rotating shaft 10 of swing roller 4.
And, in this embodiment, the distance that water inlet 51 is configured among Fig. 6 and the ejiction opening 55d right side than with the near position of distance of the ejiction opening 55d in left side.Therefore, the ejection hydraulic pressure of the ejiction opening 55d on the near right side of distance can be higher than the ejection hydraulic pressure of the ejiction opening 55d of distance.In addition,, compare, can increase spray angle with respect to the rotating shaft 10 of swing roller 4 with injection apart from the jet 53 of water inlet 51 distance from the time apart from the near jet 53 jet cleaning water of water inlet 51 distance.And the start point that can improve ejection hydraulic pressure, reduces to spray also can be to the washings jet cleaning water of swing roller 4 rear side (inboard).
On the other hand, from the time, and from apart from the near jet 53 jet cleaning water ratios of the distance of water inlet 51, also can reduce spray angle with respect to the rotating shaft 10 of swing roller 4 with respect to the jet 53 jet cleaning water of water inlet 51 distance.And, can reduce ejection hydraulic pressure, increase the start point that sprays, also can be to the washings jet cleaning water of swing roller 4 face side (open side).
Therefore, from the jet 53 in conduct and the left side shown in Figure 5 of Fig. 6 upturned position carry out rotating shaft 10 direction spreading widths towards swing roller 4 little, towards the injection of the interior side direction of swing roller 4.Therefore, even be difficult near the washings of the inside part center of wetting swing roller 4 as far as being used to injection from the jet 53 on right side with big spreading width, also can jet cleaning water.In addition, reduce the volume of this washings in the washings through near the inside part center that makes washings infiltration swing roller 4, washings is moved in swing roller 4.Its result, beating during washing washed effect and also improved, and can reduce from volume by washings and the gap that forms to washings integral spray washings.
In addition, even the washings when beginning to wash is big in the state lower volume that does not contain washings, under near the situation about circumferentially stopping up by the washings edge jet 53 in left side shown in Figure 5, also can become situation about being described below.That is, near the 1st opening 54 of swing roller 4, have the injection of big spreading width from the jet 53 on right side, near the washings the jet 53 is wetting rapidly, and volume reduces.Thus, solved near the jet 53 in the left side of causing obstruction by washings.
And, if with the set positions of water inlet 51 configuration side, then can make weak pointization of the ejection side path 16b that connects to water inlet 51 from circulating pump 20 at circulating pump 20.And, can reduce the loss of the water flow pressure in the water circulation system 16 as much as possible, and guarantee the water flow pressure of ejiction opening 55d to greatest extent.Thus; Even also can be from the higher washings of jet 53 jet water course pressure with a spot of water yield; Washings to small size or big volume all can spray more powerful washings, because washings are to the accessibility enhancing of washings, so can improve clean result.
And, further improve the jeting effect of washings through the action that is combined in the action of changing washings up and down and the left-right reversed washings when the positive and negative arc rotating drive pattern in the positive and negative continuous rotation drive pattern.
In addition, in this embodiment, even as the structure of jet 53, ejiction opening 55d, water inlet about 51 upsets also can be brought into play same effect.
(embodiment 3)
Fig. 7 is the rearview of antetheca of tank of seeing the tumbling-box washing machine of embodiment 3 of the present invention internally.In embodiment 3 of the present invention, the inscape for identical with embodiment 1 or embodiment 2 marks identical Reference numeral, omits its explanation.
As shown in Figure 7; The opening section of water inlet 51 is long-pending for S51, about being configured in respect to rotating shaft 10 among the ejiction opening 55d of 2 positions; The opening section of the ejiction opening 55d on the long-pending S55d (L) of being of the opening section of the ejiction opening 55d on the left of positive (being meant the main apparent direction of Fig. 5 in this front), positive (being meant the main apparent direction of Fig. 5 in this front) right side is long-pending to be S55d (R), sectional area ratio S55d (L)/S51=SL, sectional area ratio S55d (R)/S51=SR.
