Embodiment 5

The present embodiment describes the set-up mode of inner cylinder, the roller washing machine of prior art, between its inner cylinder and outer barrel There is a certain amount of water, described water is spilt by the hole of inner cylinder side wall.Rotary drum washing machine is also such.

Prior art is also disclosed such technical scheme, i.e. interior bucket does not have leaking hole, or, under described interior bucket Portion does not have leaking hole, if using the washing methods of traditional rotary drum washing machine, water consumption must make washed be washed It is an important premise that thing can float substantially, and therefore, the latter half of interior bucket is non-porous, it is meant that, the water level of interior bucket can not More than the position that interior bucket middle and upper part starts setting up leaking hole, when washings are more, it is clear that described washing can not be smoothly completed Process.

The technical scheme of whole non-porous interior buckets, it is necessary to the water of interior bucket is removed with the mode of centrifugation, energy consumption is may result in Increase, or, cleaning solution can not be removed completely.

But, part sets the prior art of leaking hole, with reference to technical scheme, can obtain unexpected, non- Often good effect, the method just it has been observed that impeller-type of the washings of the present invention rolls, or even can also in the case of anhydrous Rolling, optimal washing state can be carried out in the state of washings contain saturation water, therefore combine the present invention, can be reached The effect more economized on water than roller washing machine.

Test example 1

This test example is the washing machine structure to prior art, for example, CN200610149183, CN200610164325 institute Technical scheme as open, is tested in the way of rotary drum washing machine, and the model machine of described experiment is 5 kilograms with market Rotary drum washing machine convert, in order to reduce the complexity of experiment, selection is the mode for setting 3 impellers, described ripple Wheel is with six fins being uniformly arranged.

Instruction to specifications, washed clothing is 1,3,5 kilograms, and the basic, normal, high of water level is selected respectively, this Set-up mode, is the common knowledge of the rotary drum washing machine of prior art, and a basic principle of rotary drum washing machine is exactly that water level should This is higher by washings so that during impeller agitator treating liquid, current can drive washings.

As a result find, according to the traditional approach of rotary drum washing machine, effect is seethed in the rotation of the washings swum in water, Substantially not as before reequiping.

According to the instruction of CN200610149183 specification second pages, water is reduced at 1/3rd of impeller, so Rotate forward or invert simultaneously afterwards, the rollover effect of range estimation is still not so good as the rotary drum washing machine of prior art.

With reference to the instruction of CN200610164325 specifications, although the phenomenon " current of generation of document Instructions Page 3 Washings are rolled, stirred ... " it is to occur in that, still, its clean result is still not so good as prior art.

So far, for conventional process of the test, one of ordinary skill in the art should abandon further experiment.

The researcher of the present invention is found surprisingly that a kind of phenomenon in process of the test, and the washing machine after repacking starts, ripple Wheel start rotation, when impeller present 2 in the same direction, one reversely, while when being only given only seldom water, washed clothing exists A kind of obvious rolling is presented on a pair of impellers in 3 impellers, the rotation for changing motor reversely, it is found that washed clothing exists Obvious rolling is presented on another pair impeller, and they present certain angle, this phenomenon causes the research of the present invention Personnel have associated the US6220063B1 that background technology is referred to, before, and researcher of the invention studied this washing machine, by In the one-directional rotation of its actual product, " American football shape " united is presented in washings, cleans than also low, this be also the product not The reason for can commercially popularizing.

It is this to be found surprisingly that the researcher for causing the present invention contemplates, for decades, the technical staff in washing machine field Want that, by the advantage merging of rotary drum washing machine and roller washing machine, shortcoming is abandoned, and US6220063B1 gives a kind of enlightenment always, If with reference to described enlightenment, then at least forming 2 rolling directions, it should be a kind of unexpected, unprecedented technical scheme.

According to above-mentioned thinking, using the model machine of foregoing repacking, selection water level be without, it is middle and high, washings (use standard Cloth) selection 1,3,5 kilograms, experiment is found, referring to accompanying drawing 9, and accompanying drawing curve is described as follows：

This test example model machine, 5 kilograms of washings, the rolling number of times of its unit interval increases with water, is presented sinusoidal bent Line, when almost anhydrous, it is minimum that it originates rolling number of times, because washings are too many, tumbling action be difficult be transferred to by The upper strata of washings, with the increase of rate of water added, washings water content gradually increases, the frictional force increase between washings, The driving force of impeller plays a role, and when water exceedes necessarily, the gravity of washings offsets a part, washings institute by buoyancy Started reduction by the power between the driving force and clothing of impeller fin, its number of times that rolls gradually is reduced；

This test example model machine, 3 kilograms of washings, the rolling number of times of its unit interval increases with water, presents more multiple Miscellaneous curve, when almost anhydrous, it is originated, and rolling number of times is higher than 5 kilograms, and this is that washings are relatively few, tumbling action phase Upper strata to being easier to be transferred to washings, with the increase of rate of water added, washings water content gradually increases, between washings Frictional force increase, the driving force of impeller plays a role, and because washed object amount is relatively few, the maximum of its number of times that rolls is more In advance, when water continues to increase to maximum, washings are almost swum in water, and its number of times that rolls is gradually decrease to very low；

This test example model machine, 1 kilogram of washings, the rolling number of times of its unit interval increases with water, presents very multiple Miscellaneous curve, when almost anhydrous, it originates rolling number of times preferably, because washings are seldom, the rolling of impeller formation Action almost immediately, the whole of totally tansitive to washings, with the increase of rate of water added, it is easy to reach washings floating Environment, washings rolling number of times drastically declines, when water continues to increase, impeller agitation current, the washings of floating with The rolling of regular current, its number of times that rolls increases on the contrary, and when water continues to increase to maximum, the tumbling force of impeller is to current shadow Sound almost disappears, and rolling number of times of the washings in water is gradually decrease to very low；

In terms of above-mentioned experiment, even if inventors have surprisingly discovered that two rolling side can be realized in described model machine To the weight of its water consumption and washings forms the relation of complexity, if considering further that the rib on the rotating speed of impeller, impeller Shape and height, the factor such as the barrel dliameter ratio of inner cylinder, its complexity is not envisioned that, is made tentatively from foregoing model machine and experiment Screening, and the actual measurement parameter drawn with reference to accompanying drawing 9 judges, clothing rolling number of times, consider washings for it is a small amount of extremely In the case of maximum, under conditions of washings contain saturated water amount, rolling number of times is all in preferable scope.

By substantial amounts of experiment, in conventional wash, preferred slurry amount is 1.2-6.5 times of saturated water amount, excellent Select 1.4-4 times；

When using foam stream surface washing (referring to the first related application of Haier) described in prior art, preferably Slurry amount is 0.8-1.4 times, preferably 1-1.2 times of saturated water amount；

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

In the present invention, standard cloth refers to, according to cloth as defined in GB/T4288-2008 appendix As.

Saturated water amount refers to, using cloth as defined in a certain amount of GB/T4288-2008 appendix As, submerges and is used in combination in water Stir down 3 times on hand, the time that the cloth is submerged in water is 5 minutes, take out the cloth of all amounts, smooth hanging The stainless steel wire of 10-20 mesh uniformly place 5 minutes on the net (environmental condition be 20 ± 10 DEG C, wet to make the outflow of unnecessary water Degree is 25 ± 10%), at this moment, the water of cloth absorption is the saturated water amount of the specified amount cloth.

The roller washing machine of prior art has, it is non-loaded when, the rolling number of times of the clothing of its unit interval changes with water It is smaller；And rolling method of the present invention, the rolling number of times of clothing influenceed larger by water, and this is probably because this hair Bright described rolling mode, is hardly rotated the reason for distinctive centrifugal force is influenceed by roller.

Test example 2

This test example attempts in the case of laundry amounts (using standard cloth) are fixed, to change fin number on impeller, containing saturation The change of the washings rolling number of times of water；Experiment further comprises the result of the test under three kinds of washed object amounts, and experiment is used Two kinds of different unloaded impeller rotating speeds, it is intended to draw possible rule, described fin refers to from the center of impeller to impeller Edge formation projection, similar to the fin on impeller of the prior art, described fin number refers to, is fixed on impeller Fin quantity, washings are as defined above to be stated；Specific result of the test is as follows：

The rolling number of times of clothing is can be seen that from above-mentioned test data, trend is increased as fin number increases, when convex Rib count to up to it is a certain amount of when, the increase of rolling number of times tends towards stability, and considers result of the test, and fin number preferably is 3-7, More preferably 4-6.

In this test example, rolling number of times is so measured, the standard cloth of specified quantity, using three different colours (examples Such as, it is red, blue, green), size be 5*5 centimetres of cloth (quality and standard cloth close to), their a line is respectively with 3 The a line of individual standard cloth is stitched together, is then dispersed in whole standard cloth, (is maintained in rolling on a pair of impellers Rolling) after 1-2 minutes, the number of times that individual painting cloth occurs is added and removes 3 by the observation number of times that within a specified time every kind of painting cloth occurs, Rolling number of times as of the present invention.
