Prior art, usually washing machine is divided into roller washing machine, rotary drum washing machine and agitator type washing machine, such classification is not based on washing principle, more based on custom, such as, Europe is more uses tumbling-box washing machine, and Asia gets used to pulsator washing machine, and North America typically uses agitator type washing machine; In recent years, the washing machine of what is called the 4th kind of form that Chinese Enterprise is released, two-power washing machine.
Even if similar CN1170056 (Daewoo Electronics Co., Ltd, 1998.01.14) disclosed multi-impeller washing machine, also be only propose technical scheme in the thinking changing streamflow regime, the document discloses a kind of washing machine with pulsator apparatus, it is with in the clothing cylinder of pulsator apparatus a kind of, a pulsator apparatus comprises: one is arranged on the driving impeller on bottom clothing cylinder, is driven rotate by a motor; With multiple driven impeller, rotate round the axis being fixed on back shaft respective on the sidewall of clothing cylinder under the rotary actuation of driving impeller.But, it is the washing machine under usual manner disclosed in the document, namely wash solution is made to form flowing by impeller, stir and washing clothes by current, and although the gear that described gear is side is surface in the same way sees and some similarity of the present invention, object is different, means are different, and technical scheme is different
Researcher of the present invention thinks, above-mentioned washing machine can be divided into two classes in fact, and one is do not rely on current but rely on the washing machine that clothing rolls by mechanical force, such as, and tumbling-box washing machine; One to be rolled clothing by current (power), in other words, the rolling of clothing depend on the water yield number, such as, impeller, stirring and two-power washing machine.
The respective merits and demerits of above-mentioned two class washing machines have studied a lot of year, how to abandon the shortcoming of the two and is the problem that those skilled in the art study in conjunction with the advantage of two kinds always, and the MAYTAG company of the U.S. proposes useful thinking, specific as follows:
US5829277A discloses a kind of top loading machines, there is spherical washing basket, described washing basket is equipped with spherical side agitator, because its kind of drive limits, two agitators can only rotate (seeing towards during impeller) clockwise or counterclockwise with identical.Its advantage provides good stirring when a small amount of water.Although this document propose the mode that two impellers are installed in side, from its principle, its goal of the invention and technical scheme are not the effect of the upset in order to realize similar roller washing machine in perpendicular barrel washing machine.
US6220063B1 discloses a kind of washing machine, and described washing machine has gear assembly, and described is immersed in cleaning solution gradually, for driving the agitator arranged with on washing basket.Two agitators described in the document are respectively to rotate clockwise and counterclockwise, when they are tilting in mode disclosed in document, just define the tumbling effect of similar roller washing machine, certainly, it promotes the tumbling effect falling formation and is starkly lower than roller washing machine.Technical scheme disclosed in the document provides the thinking of the tumbling action at perpendicular barrel washing machine simulation roller washing machine really, but, also there is a lot of shortcoming in the program, such as, described impeller needs very large, thereon along needing and tighter the coordinating of an inner ring, to prevent clothing from entering between washing basket and urceolus, clothing can be caused like this to clamp damage washing machine, in addition, because two impeller lower ends are in conjunction with closer, easy holding clothes causes click overheated; Further, no matter two impeller lower ends are close or distant, for a small amount of clothing, are difficult to form rolling.The present invention introduces the document as main background document, and the present invention, to the omission of the description of some prior aries, all can directly quote corresponding contents disclosed in the document, and not repeat in the present invention.
It should be noted that, above-mentioned background technology and the present invention, for be the improvement of automatic washing machine because consider merely washing, utilize the mode of washing of tilting impeller to have very early open.
In fact, in the actual product of above-mentioned two Imtech of holder of the patent right U.S., the uniform impeller of the fin adopting above-mentioned open source literature to illustrate is infeasible, the impeller that U.S.'s Tyke actual product adopts is similar to the shape disclosed in CN200520133107X, except impeller structure complexity is with high costs, adopt this form that clothing can only be made to roll towards a direction, side direction is not almost had to roll, the inside and outside probability exchanged and exchange arbitrarily of clothing group is very low, except cleaning than low of clothing, also create the difference of clothes washing uniformity.
From structure, researcher of the present invention discloses a kind of vertical multi-impeller washing machine in CN101191285, comprise interior bucket, outer barrel, impeller, motor, decelerator and transmission device, it is characterized in that, described impeller is be hubbed at three or four impellers that interior bucket periphery of inner wall is 120 degree or 90 degree corresponding settings, this impeller is basin shape, is provided with the convex tendon that arris is smooth, and this impeller back side is provided with gear ring; Transmission device has the output shaft that three or four are installed impeller.But, technical scheme disclosed in this patent it is emphasised that " all impellers can forward or reverse " simultaneously, although set forth " can stereo directional upset throwing get rid of clothing " in the literature, in fact, this device cannot reach the tumbling effect being equal to roller washing machine, also cannot reach and there is two rolling surfaces obtain tumbling effect, more cannot reach and there is side direction auxiliary force to increase the effect of rolling when rolling.
In view of this, special proposition the present invention.
