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 be when having realized roughly washing in the three power washing of all rotating of bucket-center impeller-big wave wheel, but when the practical operation, clothing is more when dropping into, the rollover effect of clothing in interior bucket is poor, cleans lowlyer, washs lack of homogeneity.
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, little, the clean ratio height of a kind of clothing winding is provided and washs uniform three dynamical washing machines.
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 the 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 the drive unit that bucket-center impeller-big wave wheel rotates in the control, 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, evenly be provided with the circular-arc fin that extends to center impeller excircle from the big wave wheel excircle on the described big wave wheel, the bucket wall of described interior bucket is provided with the current that big wave wheel is rolled and is allocated to attached of interior bucket center, and the ratio of the height of fin and attached height is 1:0.8 ~ 1.2.
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 effect that fin has formation even strong outer coil vortex from bottom to top is set on the big wave wheel, the direction of motion of interior bucket and big wave wheel is opposite, arrange attached on the interior bucket bucket wall and have the drying that makes the inside bucket of outer ring eddy current flow center, the effect of turning over the spray, fin and attached relative altitude be directly connected to attached whether externally coil vortex form excessive resistance or not enough to whirlpool, outer ring drying dynamics, these two all causes forming the current that uniform a plurality of direction is seethed.The inventor is through repeatedly research discovery, the ratio of the height of fin and attached height is 1:0.8 ~ 1.2 o'clock, attached external coil vortex has less resistance and drying effect preferably, form from down to up, the uniform universal boiling current that seethe from inside to outside, be conducive to reduce the winding of clothing, the uniformity that improves clean ratio and wash, have higher clean result.
The ratio of the height of described fin and attached height is 1:0.9 ~ 1.1.
