Stir washing machine (agitatorwashingmachine) and rely on stirring vertical rod, directly or by means of waterpower drag clothing at underwater exercise, thus complete the washing of clothing.

In principle, rotary drum washing machine is extremely similar with stirring washing machine.

In the evolution of rotary drum washing machine, many documents are had to disclose the technical scheme adopting multiple impeller, such as:

FR1131586 discloses a kind of washing machine with multiple wave formalism, described multiple impellers can level also can the bottom of tilting washtub, its rotation can in the same way, direction that also can be different.

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.

The technical scheme described in prior art of above-mentioned many impellers, its basic goal is to realize complicated current, thus reducing winding, the clean ratio of raising of laundry, their goal of the invention and technical scheme are not the effect of the rolling in order to realize similar roller washing machine in perpendicular barrel washing machine.

Roller washing machine (drumwashingmachine) relies on the several fins being fixed on inner core inwall to promote clothing, and clothing repeatedly promotes in cylinder, fallen washing rinse cycle.

Prior art is thought, cleaning than high of stirring-type and pulsator washing machine (pulsatorwashingmachine), and wash time is short, and when drying at a high speed, balance is relatively easy to control; But the wearing and tearing of this kind of washing machine are comparatively large, and water consumption is comparatively large, and clothing is wound around relatively serious;

Tumbling-box washing machine (drumwashingmachine) is cleaned than low, and wear and tear little, water consumption is little, and clothing is wound around little; But its wash time needed is long, when drying at a high speed, balance relative difficult controls.

How by above-mentioned different washing machine advantages, can abandon respective shortcoming, those skilled in the art have studied decades, do not have effective way so far simultaneously.

The MAYTAG company of the U.S. proposes useful thinking, specific as follows: US6220063B1 discloses a kind of washing machine, two agitators described in the document are respectively to rotate clockwise and counterclockwise, when they are arranged by way of illustration, just define the lifting of similar roller washing machine, fall effect.

Technical scheme disclosed in the document provides really in perpendicular barrel washing machine, realizes the thinking of the tumbling action of roller washing machine with impeller.

But the program also exists a lot of shortcoming, such as, described impeller needs very large, needs to coordinate closely to prevent holding clothes in the junction of impeller and inner core; Further, no matter two impeller lower end distances, are difficult to form the process promoting and fall for a small amount of clothing; Moreover its actual product, clothing often forms the shape of a rugby in washing process, causes inside and outside clothing to exchange and causes washing uniformity to reduce.

The document, as main background document, is introduced into the present invention, and the present invention omits the description of some prior aries, all can directly quote corresponding contents disclosed in the document, and not repeat in the present invention.

CN1721610 discloses a kind of suspension double-agitator washing machine, and claim there is drum wash rollover effect, be not wound around, low wearing and tearing, have simultaneously impeller washing clean than advantage that is high, water-saving, and think peak level only reach impeller 1/4-1/2 height just can wash.But due to its not open described impeller size, the angle of setting and the internal diameter of bucket, therefore playing the water yield is a uncertain value.

In fact, impeller in the actual product of above-mentioned two Imtech of holder of the patent right U.S. is similar to the shape disclosed in CN200520133107X, CN200510080134.X, the inside and outside probability exchanged and exchange arbitrarily of clothing group is very low, causes the difference of clothes washing uniformity.

The CN101191285 (2008.06.04) applied for before applicant of the present invention discloses a kind of vertical multi-impeller washing machine, 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, during washing, enter when the water yield only need reach 1/3 of impeller height and just can wash, all impellers can simultaneously forward or reverse, washing clothes.This application is the principle utilizing prior art, the one of rotary drum washing machine is improved, due to its impeller " simultaneously forward or reverse ", therefore the rolling mode with two rolling surfaces of the present invention can not be formed, in addition, because its impeller diameter, inner core parameter etc. are uncertain, it is a non-deterministic value that described volume enters the water yield.

Apply for that CN101191286 (2008.06.04, Ju Long company) discloses a kind of multi-impeller washing machine before of the present invention, its impeller is three or four impellers, during washing, and three or four impellers in the same way or mutual not rotating Vortex within the inner barrel.According to described two embodiments, effect of the present invention can not be formed equally, and it mainly relies on current to roll to clothing, stirs, impacts, extrudes, pats and rub.

The CN201176525 applied for before applicant of the present invention discloses a kind of full automatic multi-impeller washing machine, and it mainly improves the one of the type of drive of prior art.

The product of described prior art and its reality, except impeller structure is complicated, with high costs, noise large except, maximum defect is, adopts the mode of two tilting impellers, clothing can only be made at most in rolling last time of an imaginary plane, the same with the roller washing machine of prior art, the rolling in more than one direction cannot be realized, and, when laundry amounts is few time, be difficult to realize rolling, and clothing rolls in one direction and easily forms " American football shape ".

What the present embodiment described is the set-up mode of inner core, and the roller washing machine of prior art, exists a certain amount of water between its inner core and urceolus, and described water is spilt by the hole of inner core sidewall.Rotary drum washing machine is also like this.

Prior art also has openly such technical scheme, namely, interior bucket does not have leaking hole, or, the bottom of described interior bucket does not have leaking hole, if adopt the washing methods of traditional rotary drum washing machine, it is an important prerequisite that water consumption must make substantially can be floated by the washings washed, therefore, and the latter half atresia of interior bucket, mean, the water level of interior bucket can not exceed the position that interior bucket middle and upper part starts to arrange leaking hole, when washings is many, obviously cannot complete described washing process smoothly.

The technical scheme of the interior bucket of whole atresia, must remove the water of interior bucket, may cause the increase of energy consumption, or cleaning solution can not remove completely by centrifugal mode.

But, part arranges the prior art of leaking hole, in conjunction with technical scheme of the present invention, can obtain unexpected, extraordinary effect, as aforementioned, the impeller-type rolling method of washings of the present invention, even also can roll in anhydrous situation, and best washing state can be carried out under the state of washings containing saturation water, therefore in conjunction with the present invention, the effect of more economizing on water than roller washing machine can be reached.

Test example 1

This test example is the washing machine structure to prior art, such as, such technical scheme disclosed in CN200610149183, CN200610164325, test by the mode of rotary drum washing machine, the model machine of described test converts with the rotary drum washing machine of 5 kilograms in market, in order to reduce the complexity of test, what select is the mode arranging 3 impellers, and described impeller has six fins evenly arranged.

Instruction to specifications, it is 1,3,5 kilogram by the clothing washed, select the basic, normal, high of water level respectively, this setup, be the common practise of the rotary drum washing machine of prior art, a basic principle of rotary drum washing machine is exactly that water level should exceed washings, when making impeller agitator treating liquid, current can drive washings.

Found that, according to the traditional approach of rotary drum washing machine, effect is seethed in the rotation swimming in the washings in water, before being obviously not so good as repacking.

According to the instruction of CN200610149183 description second page, the water yield is reduced to 1/3rd places of impeller, then rotates forward or reversion simultaneously, the rollover effect of range estimation is still not as the rotary drum washing machine of prior art.

With reference to the instruction of CN200610164325 description, although the phenomenon of document Instructions Page 3 " current of generation roll to washings, stir ... " has occurred, its clean result is still not as prior art.

So far, from the process of the test of routine, those of ordinary skill in the art should abandon further test.

Researcher of the present invention is unexpected in process of the test finds a kind of phenomenon, washing machine after repacking starts, impeller starts to rotate, when impeller presents 2 in the same way, one oppositely, when only giving little water simultaneously, a kind of significantly rolling is presented by a pair impeller in 3 impellers of the clothing that washs, the rotation changing motor is reverse, to find by the clothing that washs at another impeller presenting obvious rolling, and they present certain angle, this phenomenon researcher of the present invention the is associated US6220063B1 that background technology is mentioned, before, researcher of the present invention studied this washing machine, due to the one-directional rotation of its actual product, washings presents " American football shape " of uniting, clean ratio is also low, this is also the reason that this product can commercially not popularized.

This unexpected discovery makes researcher of the present invention imagine, recent decades, the technical staff in washing machine field wants the advantage of rotary drum washing machine and roller washing machine to merge always, shortcoming is abandoned, US6220063B1 gives a kind of enlightenment, if the enlightenment described in combining, more at least forms 2 rolling directions, should be a kind of unexpected, unprecedented technical scheme.

According to above-mentioned thinking, adopt the model machine of aforementioned repacking, select water level be without, middle and high, washings (adopt standard cloth) selects 1,3,5 kilogram, and test finds, see accompanying drawing 9, being described below of accompanying drawing curve:

This test example model machine, 5 kilograms of washings, the rolling number of times of its unit interval increases with the water yield, present sine curve, when almost anhydrous, its initial rolling number of times is minimum, this is because washings is too many, tumbling action is difficult to the upper strata being passed to washings, with the increase of rate of water added, washings moisture increases gradually, frictional force between washings increases, the driving force of impeller plays a role, when the water yield exceedes necessarily, the gravity of washings is offset a part by buoyancy, power between the driving force of impeller fin suffered by washings and clothing starts to reduce, its rolling number of times reduces gradually,

This test example model machine, 3 kilograms of washings, the rolling number of times of its unit interval increases with the water yield, present more complicated curve, when almost anhydrous, its initial rolling number of times is higher than 5 kilograms, this is that washings is relatively few, tumbling action is relatively easily passed to the upper strata of washings, with the increase of rate of water added, washings moisture increases gradually, frictional force between washings increases, the driving force of impeller plays a role, because washings amount is relatively few, the maximum of its rolling number of times comparatively shifts to an earlier date, when the water yield continues to be increased to maximum, washings almost swims in water, its rolling number of times is reduced to very low gradually,

This test example model machine, 1 kilogram of washings, the rolling number of times of its unit interval increases with the water yield, present very complicated curve, when almost anhydrous, its initial rolling number of times is best, this is because washings is little, the tumbling action that impeller is formed almost immediately, totally tansitive is whole to washings, with the increase of rate of water added, be easy to reach the floating environment of washings, washings rolling number of times sharply declines, when the water yield continues to increase, impeller stirs current, floating washings is along with the rolling of regular current, its rolling number of times increases on the contrary, when the water yield continues to be increased to maximum, the tumbling force of impeller almost disappears to water currents, the rolling number of times of washings in water is reduced to very low gradually,

From above-mentioned experiment, even if the present inventor has surprisingly found to realize two rolling direction in described model machine, the weight of its water consumption and washings defines complicated relation, if consider the rotating speed of impeller again, the shape of the rib on impeller and height, the factors such as the barrel dliameter ratio of inner core, its complexity is not conceivable, preliminary screening is made from aforementioned model machine and experiment, and the 9 actual measurement parameters drawn judge by reference to the accompanying drawings, clothing rolling number of times, consider washings be a small amount of to maximum when, under the condition of washings containing saturated water amount, rolling number of times is all in good scope.

By a large amount of tests, when routine is washed, preferred slurry amount is 1.2-6.5 times of saturated water amount, and preferred 1.4-4 doubly;

When adopting foam stream surface washing (see Haier's related application formerly) described in prior art, preferred slurry amount is 0.8-1.4 times of saturated water amount, and preferred 1-1.2 doubly;

During rinsing, preferred water consumption is 2.2-7.5 times of saturated water amount, and preferred 2.4-4.5 doubly;

In the present invention, standard cloth refers to, the cloth specified according to GB/T4288-2008 appendix A.

Saturated water amount refers to, adopt the cloth that a certain amount of GB/T4288-2008 appendix A specifies, in water, submergence is also with stirring 3 times down on hand, the time of described cloth submergence in water is 5 minutes, take out the cloth of whole described amount, evenly place 5 minutes at smooth unsettled 10-20 object stainless steel wire to make the unnecessary water yield flow out (environmental condition is 20 ± 10 DEG C, and humidity is 25 ± 10%) on the net, at this moment, the water yield of cloth absorption is the saturated water amount of described specified amount cloth.

The roller washing machine of prior art has, non-loaded time, the rolling number of times of the clothing of its unit interval is less with water yield change; And rolling method of the present invention, the rolling number of times of clothing is subject to the impact of the water yield comparatively greatly, and this may be because rolling mode of the present invention, hardly by the reason of the impact of the distinctive centrifugal force of drum rotating.

Test example 2

This test example attempts when laundry amounts (adopting standard cloth) is fixing, to change fin number on impeller, containing the change of the washings rolling number of times of saturated water amount; Test further comprises the result of the test under three kinds of washings amounts, test have employed two kinds of different unloaded impeller rotating speeds, attempt to draw possible rule, described fin refers to the projection that the edge from the center of impeller to impeller is formed, be similar to the fin on impeller of the prior art, described fin number refers to, is fixed on the quantity of the fin on impeller, and washings definition is as aforementioned; Concrete result of the test is as follows:

As can be seen from above-mentioned test data, the rolling number of times of clothing, trend increases along with fin number and increases, when fin count to reach a certain amount of time, rolling number of times increase tend towards stability, consider result of the test, preferred fin number is 3-7, is more preferably 4-6.

In this test example, rolling number of times is metering like this, the standard cloth of specified quantity, adopt three different colours (such as, red, blue, green), be of a size of the cloth (quality and standard cloth close to) of 5*5 centimetre, together with a side seam of their respectively with 3 the standard cloth in a limit, then be dispersed in whole standard cloth, in rolling (remain on a pair impeller and roll) after 1-2 minute, the number of times that in observation at the appointed time, often kind of painting cloth occurs, the number of times occurred by individual painting cloth is added except 3, is rolling number of times of the present invention.
