A kind of three dynamical washing machines
Technical field
The utility model belongs to the washing machine field, is 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 the utility model that proposes.
