Background technology
The structure of traditional automatic washing machine as shown in Figure 1, this washing machine is with bucket 35 outside suspension rod 38 suspention downwards in shell 39, outer bucket 35 also claims steel ladle, general outer bucket is a round tank that has tapering, play the retaining of washing machine, the effect of carrying water, leakproof and support staving electrical part, guarantee clothing under water, its content has the interior bucket 37 as washing dehydration, in bucket 37 bottom dispose impeller 36, utilize the positive and negative rotation of impeller to drive clothing, to its washing, rinsing.On the inner face of interior bucket 37, be provided with many and send water route 41, on the inner face of impeller 36, form inner wing 36a, at periphery formation and many pump chambers 42 that send water route 41 to be communicated with of inner wing 36a.The watering mouth 43 of the inside opening of inside bucket 37 is set on many tops of sending water route 41, constitutes inwardly bucket 37 inner waterings of washings through sending water route 41 to rise.Motor 44 drives impellers 36 or interior bucket 37 by V-shape belt 45 and the reducing gear clutch 46 of holding concurrently.Draining valve 47 is used for the draining with interior bucket 37 washed water; Water-supply valve 48 is used for inwardly feeding water in the bucket 37.The fluid balancer 49 of vibration covers 50 in the configuration of the top of interior bucket 37 when being set to reduce dehydration on interior bucket 37.Control device 51 is used for motor 44, draining valve 41, water-supply valve 48 etc. are controlled, and successively washing, rinsing, each program of dewatering is controlled.
In above-mentioned traditional structure, for improving the internal circulating load that the scrubbing performance of washings is increased washings, need to improve the speed of rotation of impeller 36, when improving the speed of rotation of impeller 36, bring raising to the stir speed (S.S.) of washings.When the stir speed (S.S.) that improves washings, the friction that promptly produces between the surface that makes washings friction each other, washings and impeller 36 increases, and existence makes the problem of washings damaged, particularly to the washing of high-grade clothing (as cashmere etc.).
Wash inhomogeneous for solution should improve scourability with minimizing, do not make the washings damaged again, at application number is to disclose a kind of rotation that does not rely on impeller in 98107000.0 applications for a patent for invention that are called [washing machine], make the washings circulation, reach and do not make the washings damaged, improve scourability and reduce the uneven washing machine of washing, its structure as shown in Figure 2.This washing machine be in shell 4 with the outer bucket 1 of suspension rod 3 suspention downwards, outer bucket 1 content has the interior bucket 2 as washing dehydration, motor 5 by V-shape belt 6 and reducing gear hold concurrently clutch 7 drive in barrels 2.Washings in the outer bucket 1 are discharged through draining valve 10; Water-supply valve 8 is used for inwardly feeding water in the bucket 2.Condensate tank of dehumidifier is used to detect the water level in the outer bucket 1, and control device 11 is used for motor 5, draining valve 10, water-supply valve 8 etc. are controlled, and successively washing, rinsing, each program of dewatering is controlled.
The washing machine of this invention is with bucket in the washing dehydration that rotates the drive washings to be rotated, and the formation parabola constitutes the washings rising of rotating outside interior barrel and between outer barrel, sprinkles water for inside barrel from the top.Replace the impeller fin and send the watering mouth of water route pump with water via many, the inwardly inner watering of bucket to interior bucket top.Because (the water circulation amount is big more for the penetration speed of washings circulation acceleration water, centrifugal penetration speed and dynamics are just big more), mainly utilize the penetration by water clothes fiber to finish cleansing to the clothing dirt, there are not impeller or the bucket and the rigid friction of clothing in the washing process, thereby can be implemented in and guaranteed scourability when not damaging washings, and washing does not have super rich winding, washs more even.
This invention, also by the top of bucket outside be configured to its with the top of interior bucket between form the lid of watering with the Drainage Division, can realize the washings circulation reliably, and can inwardly sprinkle water in the bucket from the watering discharge portion reliably.

The structure of the guide wall that this invention provided reaches under lower rotary speed, can make washings rise to the height of circulation watering.Yet through further analyzing, this structure also has further room for improvement.
1, at first, for inner barrel wall, the guide wall of the suitable inclination on set through top, bottom from interior bucket outer wall, its effect is not a guiding, but plays the blade effect of centrifugal pump.
Therefore, as the blade of pump to be the best perpendicular to direction of rotation, tilt in addition spiral helicine effect all too late.As the blade of pump, whether necessary from through top, the bottom of interior bucket outer wall, because the water level in the bucket has certain requirement, can not fill.Therefore blades height should design according to height of water level.
2, for outer barrel wall, the effect of guide wall is a guiding, and guide wall shape, direction be set, lifting has great role to current, the guide wall of the inclination that low-angle is provided with can produce very big resistance (comprising the positive resistance and the resistance at the back side) to current, influences water velocity, and essence is to influence lifting height, wide-angle (comprising helical form) is little to the resistance that current produce, yet the component that impels current to rise is also little.
3, the swing of the interior bucket that the guide wall of bucket inwall is rotated at a high speed easily outside this protruding the standing on is clashed into and is damaged.
Therefore, the design of guider leaves some room for improvement very much.

The specific embodiment
Embodiment one
A kind of outer bucket of efficient washer provided by the present invention with guiding gutter, its structure as shown in Figure 3, this outer bucket 100 is to be arranged in the washing machine shell, plays retaining, carries water, leakproof and support staving electrical part, guarantee that clothing is under water, its content has the interior bucket as washing dehydration.Should interior bucket be a unlimited staving suitable for reading, it is with the difference of existing outer barrel of washing machine: suitable for reading to having a plurality of guiding gutters that are communicated with staving 130 in the staving outside, this guiding gutter 130 is made of madial wall 131, lateral wall 132 and the bottom land wall 133 that is connected inside and outside sidewall; This lateral wall 132 is tangent with outer barrel wall, to reduce the retardance to current.Madial wall 131 is connected outer barrel wall with bottom land wall 133.It between the inside and outside sidewall flow-guiding mouth 110 that is communicated with staving.The madial wall 131 of guiding gutter 130 can be that the continuity of outer barrel wall cylinder is the part of staving inwall, can keep constant with the spacing of interior bucket, has avoided the convex guide wall to be rotated at a high speed and the interior bucket swing clashes into and damages.Be plane bending rising (as shown in Figure 4) with the bottom land wall 133 of the tangent guiding gutter 130 of staving inner face, its starting point is consistent with direction of rotation, riser portions and horizontal plane angle are 30 °～60 °, preferably less than 45 °, this is because the current of rotation roughly are along continuous straight runs, and the baffling direction behind the bump bottom land wall is with bottom land wall normal plane symmetry with water (flow) direction roughly.Will produce the adverse current of offsetting the rotary water current direction greater than 45 ° bottom land walls, offset flow energy.The initial surface of bottom land wall 133 is consistent with the current direction of rotation, to reduce energy loss, water can be swashed with the linear velocity of maximum along guiding gutter.The exit is axially consistent with staving or outer slightly spacious, and so design can avoid current to return.
The bottom land wall 133 of this guiding gutter 130 is a straight line with the intersection of staving cross section.
The flow-guiding mouth 110 that is somebody's turn to do outer barrel of connection staving that is uniformly distributed along the circumference is two.Also can be 3 or 4 ...The height of the bottom land wall starting point of guiding gutter 130 is about 1/3 of staving.Consider that low water level also can go up the effect of water, the height at initial position is about 1/3 of staving and highly locates to best.If too low, the formation of bottom water V-arrangement water shape is too high when influencing centrifuge washing, can influence the effect of catchmenting of low water level.
In order to make the hoisting depth of water bigger under the condition on same rotating speed, same climbing inclined-plane, this requires, and the water cross section should not be too big on the maximum of guiding gutter, is generally the 10-20 square centimeter.
Embodiment two
Fig. 5,6 is depicted as another embodiment of the present invention, and the difference of itself and embodiment one is: 1, the bottom land wall 133 of this guiding gutter 130 is a camber line with the intersection of staving cross section, becomes arc transition with sidewall.The advantage of the rounding off between arc-shaped slot diapire and the interior lateral wall 131,132 is that current can not produce the eddy current off-energy because of bump bottom land wall; 2, the last water water slope side of water is seen as an orthodrome, stands in fluid-mechanics point of view, and design can effectively solve the supply capacity of water like this.
Embodiment three
Figure 7 shows that another embodiment of the present invention figure, the difference of itself and the foregoing description one, two is: the madial wall of this guiding gutter 130 slightly bends towards the cylinder outside of outer barrel wall, is damaged by interior bucket bump further avoiding.
The present invention of being shown in Figure 8 has the installation diagram of the outer barrel of washing machine of guiding gutter, and demonstration guiding gutter 130 is located at the position on the staving 100.Be to be that example is illustrated among the figure with two guiding gutters, because the staving 100 of outer barrel of washing machine is generally circle, and casing (or claiming shell) is square, for improving the occupation of land efficient of machine,, the bucket outside outside do not increase the casing volume because of having increased guiding gutter 130, guiding gutter being arranged at four jiaos of maximum interspace places of square box, promptly being arranged near the uniform suspension rod in staving 100 outsides, is current the place ahead of being located at suspension rod specifically.Said current the place ahead is meant that when interior bucket rotation drives the washings rotation the outer bucket with guiding gutter can be offset under the impulsive force effect, and this skew should be to make the guiding gutter of outer bucket towards four jiaos of maximum interspace places, avoids clashing into casing.
This guiding gutter designing requirement inner barrel wall rotational line speed will fully take into account the rugosity and the height of staving, if interior bucket diameter is about 400mm-450mm, at 3.0m/s-5.0m/s (under this rotating speed, the retaining water shape of the water level of interior bucket when centrifugal rotation is the V-arrangement of impeller bottom band water, be the optimum state of centrifuge washing) condition under can be effectively, naturally water is collected, raise up, realize good water circulation effect.
The invention solves the circulation of water, the centrifugal penetration speed of acceleration water, cleanse clothing and established condition for realizing current.If there is not this structure, it is many to cause staving to carry water, and motor-driven can not realize, and the speed of water impact clothing and dynamics are not enough, does not reach the purpose of washing clothes.
The above only is the specific embodiment of the invention, everyly is familiar with this skill personage and makes various modifications or change very easily in view of the above, therefore, does not allly allly break away from the equivalence that claim spirit of the present invention done and replaces, and all should be included in this patent protection domain.
