Description
Technical field
The invention belongs to the washing machine field, be specifically related to a kind of three dynamical washing machines.
Background technology
The operation principle of rotary drum washing machine is that washings is immersed in the washings, relies on impeller to rotate continuously or washing machine that the mode of regularly forward and reverse rotation is washed, its advantage be simple in structure, wash degree is high, time is short, little power consumption, and shortcoming is easy winding, wearing and tearing are large, the washing lack of homogeneity.The operation principle of barrel roll laundry machine is that washings soaks in drum, be partially submerged in the washings, the washing machine that the mode of the continuous rotation of dependence drum or regularly forward and reverse rotation is washed, its advantage is that winding is little, and the washing scope is wide, and it is little to wear and tear, the washing uniformity is high, shortcoming is to use duration, and power consumption is large, and volume is large and heavy.
At present, a kind of three dynamical washing machines of newtype have appearred in the washing machine field, comprise outer barrel, interior bucket, big wave wheel and small wave wheel, the direction of rotation of bucket and big wave wheel is opposite wherein, operation principle is that washings is immersed in the washings, the different generation boiling current of the size of the rotating speed of bucket, big wave wheel and small wave wheel and direction of rotation in relying on, clothing is carried out multi-faceted washing by rubbing with the hands, it has reduced winding and the wearing and tearing of clothing with respect to rotary drum washing machine, has shortened the laundry time with respect to barrel roll laundry machine.
CN200610049377.1 discloses a kind of powered washing machine with three speed ratios, comprise interior bucket, be positioned at the center impeller of bottom of the barrel, be set in big wave wheel and the planetary speed reducing clutch of impeller periphery, center, wherein interior bucket has the bottom, and big wave wheel and center impeller all are positioned on the bottom of this bucket.Wherein in the bucket inconsistent with the rotary speed of center impeller, and with the two one of direction of rotation opposite, formed the current that can roll.
CN200610063863.9 discloses a kind of decelerating clutch of washing machine and washing machine and mode of washing, the output shaft of speed-reducing clutch is small echo wheel shaft, big wave wheel axle and interior bucket axle, the small echo wheel shaft is supported in the big wave wheel axle, the big wave wheel axle is supported in the interior bucket axle, can drive simultaneously large small wave wheel and interior bucket rotation.The small wave wheel of washing machine is packed on the small echo wheel shaft, is positioned at the middle position of big wave wheel, and big wave wheel is contained on the big wave wheel axle, and interior barreled is on interior bucket axle.Its mode of washing is: small wave wheel, big wave wheel, interior bucket three be the two-way in proportion reciprocating rotary of reverse not synchronized different corners mutually, produces complicated crisscross current.
Above-mentioned patent all is three power washings that interior bucket-center impeller-big wave wheel all rotates when having realized roughly washing, but when practical operation, clothing is more when dropping into, the rollover effect of clothing in interior bucket is poor, clean lower, the washing lack of homogeneity, the concentrated wear of clothing is larger.
In view of this, special proposition the present invention.
Summary of the invention
The object of the invention is to be to overcome the deficiencies in the prior art, provide a kind of wear of clothes little of, clean high, uniform three dynamical washing machines of washing.
In order to realize purpose of the present invention, adopt following technical scheme:
A kind of three dynamical washing machines, comprise outer barrel, be located at interior bucket in the outer barrel, be located at bottom of the barrel with interior bucket coaxial mounted center impeller and big wave wheel and control in the drive unit of bucket-center impeller-big wave wheel rotation, described center impeller is positioned at the top of the center of big wave wheel, described center impeller-big wave wheel-Nei bucket simultaneously with clockwise-counterclockwise-clockwise direction does crankmotion, the diameter of described big wave wheel is 39:43 ~ 53 with the diameter ratio of interior bucket, is preferably 39:45 ~ 50.
Three dynamical washing machines are when the rinsing state, center impeller-big wave wheel-Nei bucket simultaneously with clockwise-counterclockwise-clockwise direction does crankmotion, the rotation of center impeller and big wave wheel has produced inside and outside two eddy current that the direction of motion is opposite, the rotation direction of interior bucket is opposite with the direction of motion of outer coil vortex, inner barrel wall and outer coil vortex produced strong frictional impact cause outer eddy current inwardly the rolling of bucket center and further with the eddy current strong collision of inside and outside both direction, finally formed a plurality of directions rolling seethe current.The inventor finds, the diameter of the impeller dish that big wave wheel and center impeller form directly has influence on the big or small and strong and weak of inside and outside two eddy current with respect to the size of interior bucket diameter, and then impact center impeller-big wave wheel-Nei whether form the dynamics of effectively seething current, rolling and the uniformity coefficient of a plurality of directions under the bucket acting in conjunction, finally affect clean ratio and the washing uniformity coefficient of clothing.Because the center impeller is positioned at the top of big wave wheel middle position, in fact the diameter of the impeller dish that big wave wheel and center impeller form is exactly the diameter of big wave wheel, the diameter of the diameter of big wave wheel and interior bucket is than being 39:43 ~ 53 o'clock, inside and outside two eddy current of two impeller rotation generations from below to up, evenly strong from inside to outside, and under the effect of outer barrel, form the current that seethe of the efficiently strong rolling of uniform a plurality of directions, current penetrate clothing from a plurality of directions, simultaneously between clothing, between clothing and the interior bucket bucket wall, friction and bump have been produced between clothing and the multi-direction current that seethe, thereby produced the clean result of rubbing, the clean ratio of clothing and the uniformity of washing have been improved, in addition, owing to produced the boiling current of multi-direction rolling during rinsing, overcome the problem that the single clothing that causes of rotary drum washing machine flow form easily twines, alleviated the wearing and tearing of washing machine to clothing.
The bucket end of described interior bucket, be provided with the retainer plate from the lower circumference of interior bucket bucket wall to the excircle of big wave wheel, described retainer plate is provided with the projection of the water movement that can stop that big wave wheel is rolled, the cambered surface of described projection end face for swelling gradually to the centre from the internal and external circumference two ends of retainer plate.
Described center impeller is round table-like structure, and the ratio of the diameter of center impeller and height is 6 ~ 13:13, is preferably 7 ~ 9:13.
