Description

Dewaterring washing machine
The present invention relates to the positive and negative rotation mode laundry of the stirring body that sets by the cylinder body inner bottom part, by the washing machine that has dehydrating function concurrently (calling Dewaterring washing machine in the following text) of cylinder body rotation mode dehydration.
In the past, the cylinder body of this Dewaterring washing machine had laundry and dehydrating function concurrently, by the positive and negative rotation of stirring body that the cylinder body inner bottom part sets, washings was stirred and washed, and the cylinder body rotation is dewatered.
In (e), traditional Dewaterring washing machine stirring body 1-5 is shown respectively at Fig. 5 (a).Circular base plate 1a separately-5a is provided with the radial blade 1b-5b of projection.Wherein, 1b, 2b, 4b, 5b blade are linearly, and the 3b blade is a bending.In these figure, blade 1b-5b is symmetric equidistant setting, rotates along with stirring body 1-5 each positive and negative (clockwise with counterclockwise) two-way rotation.And stirring body 1-5 is the parts of periphery separately, for example at each stirring body 1-5 peripheral part, are provided with radial protuberance 6-10 equally.
Yet, adopt the big capacity washing of conventional dehydration formula two purpose washing machine, particularly recent development of above-mentioned such stirring body 1-5 modes and the two purpose washing machine of dehydration, not only be difficult to fully clean clothing, and very easily washings stirred into one, so be difficult for taking-up.In addition, when dehydration, it also can cause the load of cylinder body rotation unbalanced, is easy to generate abnormal vibrations.
In view of the above problems, the object of the invention is to provide a kind of and obtains sufficient washability, and takes out the Dewaterring washing machine that washings and dehydration the time can also reduce abnormal vibrations easily.
For achieving the above object, the technical solution used in the present invention is the positive and negative rotation mode laundry of a kind of stirring body that is set by the cylinder body inner bottom part, by the two purpose washing machine of cylinder body rotation mode dehydration, it is characterized in that above-mentioned stirring body is by the tabular basal disc and is arranged on a side on the basal disc, central and is the blade that radiates linear projections, the outer positive veer of side direction Monday or reverse directions angled protrusions and is constituted.
At this moment, the length of the blade of stirring body radiation linearity part preferably equates substantially with length on being projected in the sloping portion radius.
Again, for well, its crooked radius of curvature preferably is set at substantially with the basal disc radius and equates the blade lean of stirring body part with bending.
And the blade angle that stands on the stirring body basal disc preferably is set at the outside face of inclination greater than inboard facial.
In addition, on the parts of stirring body periphery, the protuberance of formation is the uniform distances equal number with the blade of stirring body preferably.Again, the incline direction of its protuberance preferably forms oppositely with the incline direction of the blade lean of stirring body part.
In general, the cleaning function of washing machine is divided into two kinds of mechanical force and chemical forces, and as strengthening mechanical force, chemical force is also brought into play effect easily, and washability is strengthened.In the past, this mechanical force is considered is that friction by stirring body and washings plays a major role, but in the Dewaterring washing machine that the washings capacity of exploitation in recent years increases, because of washings can not be all with stirring body contact, so reduced the effect of frictional force.
Again, the effect of stirring body blade has two kinds usually.A kind of is by the pumping action that blade rotation produces water to be flowed, and by this current dissolving detergent, and washings is out of shape wash, and another kind is by blade drive washings itself, washings is out of shape washs.
Therefore, when inquiring into traditional Dewaterring washing machine stirring body, can obtain following conclusion to water in the cylinder body and washings role.
That is, well-known, in Dewaterring washing machine, owing to adopt rotary dehydration, cylinder body is made into cylindric, in the central authorities of its cylinder body inner bottom part, disposes concentric stirring body.As previously mentioned, on the traditional type stirring body that adopts this structure, has the identical shaped blade of symmetry, rotate along both forward and reverse directions together, in positive and negative rotation of short period (for example, make drive motors energising in 1-2 seconds, 0.5 after the outage in-1 second, again oppositely by the same way as power on/off, and repeatedly with this) in the process, because of washings just carries out the motion of roughly the same amount on both forward and reverse directions, the washings relative position does not change substantially, so washings seldom has motions such as counter-rotating, can not look to the washability increase, also can make and wash spot and increase.
Increase for making washability, if increase the rotation driving time of stirring body again,, because of the mechanicalness effect of blade, washings can only form rotatory situation, so, because washings increases with respect to the proportion of water, thereby the phenomenon that causes washings to compile to central authorities.Its result, washings is formed one after assembling, though rotation, washings seldom can be out of shape, and can not increase washability with going round and round.Moreover, the outside washings that clumps together can be accelerated to damage.In addition, when dehydration, a side of the washings deflection cylinder body that clumps together, the load when causing the cylinder body rotation is seriously unbalance, thereby produces the unusual big vibration and the sound.In this case, huge vibration can cause the lost of life of product itself.
To this, as mentioned above, stirring body of the present invention has flat circular base plate and is located on the basal disc, central authorities' one side is the radiation linear projections, the blade of outer positive veer of side direction Monday or reverse directions angled protrusions, because the blade with the positive and negative two-way rotation of stirring body is the asymmetry setting, forward or reverse by stirring body, mechanical force and flow force that blade is produced form adverse effect, thereby row and complicated are more strengthened in the motion that makes washings and water, to improve washability, and, can take out washings easily, the abnormal vibrations that produces in the time of reducing dehydration.
Again, on this basis, particularly the length of the radiation linearity of stirring body blade part is made substantially with the length on being projected in the sloping portion radius and equated,, can make balance be in optimum state because of the mechanical force of blade generation and the effect of flow force.
And, the sloping portion of stirring body blade is processed into bending, can make the motion of washings and water more smooth and easy.On this basis, again that it is crooked radius of curvature is set at the basal disc radius and equates substantially, and the motion that can obtain washings and water is effect more smoothly.
By standing on outside face that blade angle on the stirring body basal disc is set at inclination greater than inboard facial, mechanical force and flow force balance that blade is produced when the medial and lateral of its inclination direction is rotated respectively are in shape.
On the other hand, by form on the parts of stirring body periphery that quantity is equal to and with the protuberance of blade uniform distances, because of the effect of its protuberance, the motion that changes on the motion of washings and the current direction is produced effect more.On this basis, form reverse state, can further improve the effect that changes on the motion of washings and the current direction by incline direction with the blade lean part of the incline direction of its protuberance and stirring body.

Fig. 2 is the local amplification profile of the A-A line along Fig. 1.
Fig. 3 is whole side elevation in partial section.
Fig. 4 is the figure that is equal to Fig. 1 of expression the present invention the 2nd embodiment.
Fig. 5 (a)-(e) for represent respectively 5 kinds in the past example dwindle figure with Fig. 1 is equal to.
Below, referring to figs. 1 through Fig. 3, the present invention the 1st embodiment is made an explanation.
Fig. 3 is the shell 11 of expression Dewaterring washing machine integral body, and portion is equipped with outer shell 12 within it, by elastic bearing mechanism 13 (only making the part diagram) supporting, in outer shell 12, is equipped with inner casing 14.Again, in inner casing 14, be equipped with metal inner cover 15 such as the stainless steel that almost covers its whole inner peripheral surface and encase the bottom 16 of bottom, gimbal 17 also is housed, be equipped with concentric stirring body 18 at the cylinder inner bottom part in the upper edge of inner casing 14.
Following quadrate part in outer shell 12 outsides is equipped with draining valve 19, also is equipped with the driving mechanism 21 based on motor simultaneously, and by this driving mechanism 21, the rotation of locking inner casing 14 when washing makes stirring body 18 by clockwise and two-way positive and negative rotation counterclockwise.When dehydration, make the unidirectional together high speed rotation of inner casing 14 and stirring body 18.The principle of dehydration is to rely on inner casing 14 centrifugal force of rotation generation at a high speed, the water that makes washings (not illustrating) is separated by the limbers 22 of inner cover 15, again by the action of drawing water of the inner cover 15 and the gap of inner casing 14 inner peripheral surfaces, from dewatering hole 23 drainings of inner casing 14 upper ends.
Stirring body 18 specifically can adopt the formed products of making as plastics, as shown in Figure 1, be that a kind of to include washing that central part is installed in above-mentioned driving mechanism 21 for example be the structure of 6 blades with circular base plate 25 on the output shaft 24 (with reference to Fig. 2) and the convex that is provided with on its basal disc 25.If be described further, these blades 26 are the radiation linear projections in basal disc 25 central sides again, and Monday, side was then to stirring body 18 positive veers or reverse directions (being clockwise direction among Fig. 1) angled protrusions outside.
Again, the length L 1 of the radiation linearity part 26a of the blade 26 of above-mentioned stirring body 18 equates (being about 1: 1) substantially with length L 2 on being projected in sloping portion 26b radius.And, its sloping portion 26b is a bending, specifically, the diameter D of basal disc 25 is decided to be 343 (mm), the radius of curvature r of sloping portion 26b bending is decided to be 150 (mm), and the radius of curvature r that can set sloping portion 26b bending thus equates substantially with the radius (D/2) of basal disc 25.In addition, the deviate S of the sloping portion 26b leading section of extending from radiation linearity part 26a is 25 (mm).
And as shown in Figure 2, the angle that stands on the blade 26 on the basal disc 25 then is defined as α>β when outside face one side that will tilt is set at α, an inboard facial side for β.That is, the facial upright angle [alpha] in the outside of inclination should be greater than inboard facial upright angle beta.
In addition, on the above-mentioned base plate 16 of stirring body 18 periphery parts, be formed with quantity that be equal to radiation linearity protuberances 27 blade 26 same spacings.
Below, the washing machine of said structure is done as an explanation.At first introduce the mechanical force aspect, as previously mentioned, when stirring body 18 rotation, because of the effect of blade 26, rely on centrifugal force receive in the inner casing 14 water (not illustrating) afterwards, draining laterally is so washings is attracted to 26 in the blade of stirring body 18.At this moment, during stirring body 18 is rotated counterclockwise, because blade 26 is clockwise inclination form, therefore even the effect that can produce a kind of extrapolated washings will be when washings will be formed one, because of the effect of this power, can untie the group that washings is formed, produce the motion of globality expansion.
Then, when turning clockwise, because of the effect of current, washings is attracted to stirring body 18, produces the motion of drawing close to central authorities.
By above two kinds of motions, washings is produced a kind of the dynamic of direction of radiating, form one effect owing to can restrain washings, washability is strengthened.By turning clockwise and being rotated counterclockwise, make the motion of washings obviously produce conversion again,, therefore, in the inner casing 14 of Dewaterring washing machine with concentric shape stirring body 18, also can to washings produce a kind of variational dynamically, to promote counter-rotating up and down.
Secondly, the work to current is used as an explanation.When stirring body 18 rotations, rely on centrifugal force, water is drawn to the outside from the inboard, produce the effect of pump.The effect of this pump is an important factor, except making the washings motion, also has the function of dissolving detergent.In the stirring body 18 of said structure,, therefore on this part,, can produce required flow force basically along with the rotation of left and right sides both direction because basal disc 25 central sides are provided with the radiation linearity blade 26 of projection.
When being rotated counterclockwise, be drawn to the current grow of lateral direction.As previously mentioned, if only apply revolving force to washings, though washings can be wrapped in together, but when it is in this when being rotated counterclockwise state, the motion of water not only acts on direction of rotation, and can pretend usefulness to the power generation of radiating direction, thus make a kind of strength that the drench pit side is upwards held up of water generates, Here it is strengthens the reason place that prevents that washings from clumping together and acting on.
Secondly, when turning clockwise, the adverse effect of once water being forced to push back direction of rotation can be produced again,, the motion of washings itself can also be strengthened by this flow force.
In the present invention who adopts structure like this, by rotating and reverse of stirring body 18, make the mechanical force and the flow force of blade 26 generations of stirring body 18 produce adverse effect, thereby the motion that makes washings and water is stronger and complicated, can be repeatedly repeatedly to washings be out of shape, actions such as compression and stretching, to improve washability.
In following table 1, Dewaterring washing machine that stirring body 18 of the present invention is housed and the result of the test that the Dewaterring washing machine of traditional type stirring body is housed are shown.

Result from table 1 as can be seen, no matter Dewaterring washing machine of the present invention is cleaning than aspect little which of high, the weak point of washing the lacking of spot, cloth (washings) take-off time and vibration amplitude, all good than traditional Dewaterring washing machine.
Particularly pass through length L with the blade 26 radiation linearity part 26a of stirring body 18 1With the length L that is projected on the sloping portion 26b radius 2Make equally substantially, the mechanical force that produces because of blade 26 and the effect of flow force can make balance be in optimum state.
Again, be processed into bending, can make the motion of washings and water more smooth and easy by sloping portion 26b with the blade 26 of stirring body 18.On this basis, again that it is crooked radius of curvature r is set at the radius (D/2) of basal disc 25 and equates substantially, and the motion that can improve washings and water is effect more smoothly.
And, stirring body 18 is at the sloping portion 26b of blade 26 during to interior side direction (clockwise) rotation of tilting and when direction (counterclockwise) is rotated laterally, should avoid power that the former produces greater than the latter, for this reason, blade 26 angle initializations by will standing on basal disc 25 for the outside face that tilts greater than inboard facial (α>β), mechanical force and flow force balance that blade 26 is produced when the medial and lateral of its inclination direction is rotated respectively are in shape, and can obtain the effect that phenomenons such as spot are washed in the balance and the minimizing of washings generation.
On the other hand, by on the bottom 16 of stirring body 18 periphery parts, forming protuberance 27, can strengthen the effect that the sloping portion 26b by the blade 26 of stirring body 18 is produced, and can reduce the entanglement of washings and further improve washability.That is, aspect flow force, because protuberance 27 can play the function of a kind of static blade in the pump, the current of the radiation direction that produces when stirring body 18 is rotated counterclockwise change the current that upwards rise along inner casing 14 medial surfaces into, can play facilitation.Therefore, can obtain the supression washings and form one effect.In addition, aspect mechanism, when stirring body 18 is rotated counterclockwise,, make extrapolated washings motion change above-below direction into, so that the counter-rotating up and down of washings action is carried out smoothly because of the effect of protuberance 27.
On this basis, by form that quantity is equal to and with the protuberance 27 of the blade 26 same spacings of stirring body 18, can make the protuberance 27 and the blade 26 of stirring body 18 be in 1: 1 corresponding states, as mentioned above, can make the motion of washings and change current into go up direction motion more to produce effect.
Fig. 4 is expression the 2nd embodiment of the present invention, protuberance 28 is replaced above-mentioned protuberance 27, its incline direction forms opposite state with the incline direction of the blade 26 sloping portion 26b of stirring body 18, can further improve the motion of washings and changes current into the upward effect of direction motion.
Except bottom 16, the parts of stirring body 18 periphery also can adopt for example bottom formation of inner casing 14.In this case, protuberance 27,28 preferably forms on the bottom of cylinder 14 within it.
Dewaterring washing machine of the present invention has following effect.
(1) does washing in the stirring body positive and negative rotation mode that is set by cylinder body inner bottom part, in the two purpose washing machine by the dehydration of cylinder body rotation mode, because above-mentioned stirring body is by dull and stereotyped shape base dish and be located on the base dish, a central side is radiation straight line shape projection, outer Monday, the blade of side direction forward direction or reverse directions angled protrusions consisted of, thereby can make washings and water movement stronger and complicated, to improve washability, and, can take out easily washings, the abnormal vibrations that produces in the time of reducing again dehydration.
