The present invention relates to a washing machine which can generate strong ascending/descending water flow at a low cost. A water discharge opening 35 is formed inside a periphery rib 34 of a rotation blade 14 mounted on the bottom part of this washing and dehydrating machine 12. When the rotation blade 14 is rotated, water sucked by the pumping action of a back vane 33 through a water port 41 is flowed from the inner periphery toward the outer periphery through the inner periphery of the rotation blade 14 and spouted upward from the water discharge opening 35. It is preferable to form the water discharge opening 35 integrally with the rotation blade 14 and, since no water discharge opening is required on the washing and dehydrating machine 12 itself, the structure can be made simple.
Description
The present invention relates to washing machine.
In washing machine, not only the horizontal direction current that produce of the rotation by rotary blade but also the current that add above-below direction can improve the performance of washing and rinsing.For example, for washing machine in the past, in the washing and dewatering bucket, form drain outlet around the rotary blade of diapire face in, be provided with the circulation waterway that is connected with this drainage openings from the rotary blade downside with space between washing and dewatering bucket diapire.If make rotary blade rotation, the pump-absorb action of the intra vane by rotary blade rises current, and the water that sucts from below sprays in the washing and dewatering bucket from drainage openings by circulation waterway.
, for above-mentioned washing machine in the past, owing to be necessary on the washing and dewatering bucket, drainage openings to be set, so the problem that its complex structure, cost are uprised is arranged.
The present invention finishes in order to solve above-mentioned problem, and it is simple in structure that its purpose is to provide, and produces the current of above-below direction in the washing and dewatering bucket, makes washing and rinsing performance height and the low washing machine of cost.
In order to solve feature of the present invention that above-mentioned problem finishes is to be furnished with in the washing machine that rotary blade that water, rotation in the outer bucket of washing and dewatering bucket be located at this washing and dewatering bucket bottom carries out the washing of washings and rinsing in inside, below above-mentioned rotary blade, be provided with in the radial intra vane, on this rotary blade, form the drainage openings that above-below direction connects.
If in washing or rinse cycle, make rotary blade rotation, the pump-absorb action of the intra vane by rotary blade, the water from the outer bucket side direction washing and dewatering bucket side draught sprays from the drainage openings that forms at rotary blade.Thus, in the washing and dewatering bucket, produce strong ascending current.Because rotary blade rotation itself, the upward spray position of water also rotates mobile, and the washings in the washing and dewatering bucket contacts current all sidedly.
The position that forms drainage openings can be selected in the appropriate location of rotary blade, but particularly forms on the flat that does not form the leaf body above the rotary blade.That is, for flat because the space of washing and dewatering bucket diapire face below the rotary blade is narrow and small, thus make the water that sucts increased pressure, increase from the spray power waterborne of drainage openings.Certainly, than on the leaf body portion of shape, forming the easier manufacturing of drainage openings with more complicated.
In addition, preferably form the water flowing opening on the diapire face of the washing and dewatering bucket under interior all sides of rotary blade, drainage openings is located at the outer circumferential side of rotary blade.This is to arrive outer circumferential side more because of the water that the water flowing opening by interior all sides drinks up from the below to improve hydraulic pressure more, if the water outlet opening is located at outer circumferential side, can spray the bigger water of power.
In order in the washing and dewatering bucket, to produce stronger ascending current, wish downside at rotary blade, the water efficiently at the drainage openings place, and do not make this aqueous dispersion ground do not become upward to current.
For this reason, drainage openings is located at the outer circumferential side of rotary blade, make than radial intra vane gap little be shaped as good.Therefore, be clipped in abutting connection with the water of intra vane and put together towards drainage openings.And then if form the flange that the intra vane of both sides is connected with the drainage openings two ends respectively below rotary blade, drainage openings can more effectively lead water.
In addition, full week is provided with outstanding periphery longways downwards near the outer peripheral edges below rotary blade, forms drainage openings in interior all sides of this periphery, and the periphery that will be positioned at this drainage openings part makes than the high structure of other parts to better.
In addition, not only at the flange of the horizontally set water guide of the drainage openings of rotary blade inner face as described above, also can make the drainage openings downside be provided with from outer circumferential side extend, the structure of the guide plate of interior all side openings.
And then, need only the shipwreck that sucts by the pump-absorb action that utilizes intra vane and discharge with periphery acies from rotary blade, near the hydraulic pressure of drainage openings is uprised, just can further increase going up of water and spray power.For this reason, for example, can form in the periphery outside of rotary blade, by the flange and the big water route of periphery formation flow resistance of this washing and dewatering groove side from the outstanding upward flange of the diapire of washing and dewatering bucket.
In addition, drainage openings forms elongated shape along the circumferencial direction of rotary blade, can prevent when washing and rinsing that the button etc. of clothes from tangling.
Moreover, below pivoting leaf, the cowling panel that several are roughly divided drainage openings is set along diametric(al), can upwards spray water fifty-fifty from 1 drainage openings.Therefore, such cowling panel also can be cut apart drainage openings fully, perhaps, also can make each cowling panel and not exclusively cut apart drainage openings, and the part of drainage openings has common opening.
According to washing machine of the present invention, owing to when washing and rinsing, in the washing and dewatering bucket, produce strong ascending current, thus can promote that washings stirs up and down, and in washings, pass through strong current fully.Thus, can improve washing and rinsing performance.
In addition, according to washing machine of the present invention, because drainage openings whole formation on rotary blade, and on the washing and dewatering bucket, do not need to be provided with drainage openings, so lower than washing machine cost in the past.
