Technical field
The present invention relates to a kind of tumbling-box washing machine, relate in particular to a kind of like this tumbling-box washing machine, wherein install so that the clothing that will wash is easily packed into and the lifter (lifter) of the axial stretching, extension of the periphery arrangement of the inner peripheral surface of the rotary barrel that takes out has the structure of improvement being inclined upwardly, therefore, can on scourability, be improved.
Background technology
Traditional washing machine generally comprises: housing, the outward appearance of formation washing machine; The column bucket is installed in the housing and is suitable for holding washings; The column rotary barrel is installed in the bucket rotatably and is suitable for washing the clothing that wherein holds; Drive motors is installed in the bucket back and is suitable for making the rotary barrel rotation; And door, be installed in the housing antetheca with the hinge form.
Different lifters is projected into the height of hope from the inner peripheral surface of rotary barrel, arranges spaced reciprocally circumferentially around rotary barrel, and axially stretches along the inner peripheral surface of rotary barrel.When rotary barrel rotated, lifter promoted clothing in the rotary barrel and washings in a continuous manner, throw then down, thus washing clothes.
Provide opening at bucket and rotary barrel front end separately, thus can be by their opening and closing of goalkeeper.When opening, can clothing be put into rotary barrel or clothing be taken out from rotary barrel by opening by opening.When closing, the outside of bucket and rotary barrel and door seals.In this state, can carry out wash cycle.
In having the tumbling-box washing machine of said structure, pack into and take out clothing by the door that is installed in the housing antetheca.But, because the housing of above-mentioned tumbling-box washing machine typically has the height more much lower than people's average height, and the opening of rotary barrel is in forward direction, so in order to pack into by the opening of rotary barrel after opening door and to take out clothing, the user must bend over the reduction posture.Therefore, there is inconvenience.
In order to eliminate these inconvenience, the tumbling-box washing machine that improves has been proposed recently.In this tumbling-box washing machine, its opening is on the direction that makes progress thereby rotary barrel is inclined upwardly, so the user does not need to bend over very much just can to carry out packing into of clothing and takes out.
At this its intermediate roll is that a large amount of relatively clothings are positioned at the rear end part of rotary barrel in the structure of inclination, and the relatively little clothing of amount is positioned at the fore-end of rotary barrel.Especially, because the constant height that the lifter on the inner peripheral surface of rotary barrel has the length that runs through rotary barrel, be stacked upon than on the quite high horizontal plane of the height of lifter so be positioned at the clothing of rotary barrel rear end part, and the clothing that is positioned at the fore-end of rotary barrel is stacked upon than on the low horizontal plane of the height of lifter.
Therefore when rotary barrel rotated in this state, the rear end part that lifter may not be lifted at rotary barrel was positioned at than the clothing on the high horizontal plane of the height of lifter, effective washing clothes.On the other hand, it is less relatively to be raised the amount of the clothing that device promotes at the fore-end of rotary barrel.As a result, the operational efficiency of lifter is low.
In addition, when lifter rotated along with rotary barrel, not being raised the clothing that device promotes at the rear end part of rotary barrel may be snarled.Consequently, may damage clothing.Also having inconvenience is that the user must untie the clothing that snarls after finishing washing process.
Simultaneously, the clothing relatively in a small amount that distributes at the fore-end of rotary barrel is raised device at an easy rate and promotes, and the rear end part towards rotary barrel moves then.Consequently, clothing even easier rear end part at rotary barrel roll into a mass by kneading.
When clothing mainly was positioned at the rear end part of rotary barrel, because big relatively load puts on the rear end part of rotary barrel, and relatively little load put on the fore-end of rotary barrel, therefore can produce the power imbalance.As a result, the rotary manipulation operational efficiency of rotary barrel is low.
Because the rotary barrel of traditional tumbling-box washing machine is inclined upwardly and stretches forward, and the lifter of arranging thereon has constant height, so the washings of bottom of rotary barrel of fore-end that mix with washing agent and be introduced in lifter spray downwards by the hole for water spraying that is arranged on the lifter then along with the motion that lifter makes progress is raised.Yet the amount of the washings by water jet ejection is very little.A large amount of washings flow to the rear end part of lifter.Therefore because this reason, the clothing that is arranged in the rotary barrel fore-end can not be immersed in washings fully, washing clothes effectively.

The specific embodiment
Below, describing embodiments of the invention in detail with reference to accompanying drawing, its example is enumerated in the accompanying drawings, and wherein identical label is represented identical parts all the time.Embodiment is described with reference to the accompanying drawings to explain the present invention.
Fig. 1 is the sectional view that schematically shows according to the structure of tumbling-box washing machine of the present invention.As shown in fig. 1, in order to wash and pack into clothing in the rotary barrel 3 of spin-dry, tumbling-box washing machine according to the present invention comprises: housing 1, be similar to box-like, to limit the outward appearance of washing machine; Cydariform bucket 2 is installed in the housing 1 and is suitable for holding washings; Cydariform rotary barrel 3 is arranged in bucket 2 rotatably and has centrifugal dehydration hole 4 on the peripheral wall that is positioned at rotary barrel; With so that rotary barrel 3 motor rotating 5.
Opening 2a and 3a are provided at bucket 2 and rotary barrel 3 front end separately, so that clothing is put into rotary barrel 3 and take out from rotary barrel 3.Door 6 is installed on the antetheca of housing 1 with the hinge form, to open and close the opening 2a and the 3a of bucket 2 and rotary barrel 3.
The washings water supply pipe 7 and the detergent container 8 that is used for holding washing agent that is used for receiving from external water source installed at the top of housing 1, and mixes with washing agent with through the washings that water supply pipe 7 provides.Draining pump 9 and drainpipe 10 are installed on the bottom of housing 1, to discharge washings to the external world after finishing wash cycle.
Be fixedly mounted in the rear end of bucket 2 at the outside of bucket 2 drive motors 5.The other end that the one end connects the rotating shaft 5a of drive motors 5 is fixedly attached to the rear end of rotation bucket 3, thereby revolving force is sent to rotary barrel 3 from drive motors 5, therefore makes rotary barrel 3 rotate.
Its advantage is that the inclination angle of rotary barrel 3 can be big as much as possible, to pack in the front of housing 1 easily and to take out clothing.Yet when inclined angle alpha was excessive, the amount of clothing that is positioned at 3 rear end part of rotary barrel also increased too much, thereby the deterioration of scourability can take place.Therefore, consider the convenience and the laundry performance of packing into and taking out the operation of clothing, preferably the inclined angle alpha of rotary barrel 3 is determined in about 5 ° to 15 ° scopes.
Because rotary barrel 3 towards the acclivitous layout of the antetheca of housing 1, is compared with the fore-end of the rotary barrel 3 that is connected with door 6, the clothing that holds in the rotary barrel 3 may mainly be positioned at the rear end part of the rotary barrel that links to each other with the rear wall of housing 1.In order to promote the clothing that is in this state effectively, lifter 20 has the height that reduces gradually towards its front end extension along with the rear end from rotary barrel 3.This structure with reference to Fig. 2 to 5 pair of lifter in the back is described.
Fig. 2 and 3 is sectional view and perspective views of the structure of the lifter on the inner peripheral surface that is arranged in rotary barrel shown in the presentation graphs 1 respectively.
As shown in Figure 2, rotary barrel 3 is inclined upwardly with the antetheca of α angle towards housing 1 (Fig. 1), thus the central shaft of rotary barrel, i.e. center line C
1-C
1, with horizontal line H

1Intersect with angle [alpha].According to this layout, to compare with the fore-end of rotary barrel 3, a large amount of relatively clothings is positioned at the rear end part of rotary barrel 3.
Similarly, each lifter 20 has along with its rear end forward end extension from rotary barrel 3 has the height that reduces gradually, thereby intersects with angle [alpha] along the top of lifter and the lines of bottom 21 and 22 extensions respectively.According to this structure, when lifter 20 is positioned at the floor level face of rotary barrel 3, the top 21 and the horizontal line H of lifter 20
1-H
1Parallel.
Here, the bottom 22 of each lifter 20 is the lifter parts that contact with the inner peripheral surface of rotary barrel 3, and the top 21 of each lifter 20 is lifter parts of leaving ultimate range with the inner peripheral surface of rotary barrel 3.
According to its this structure, when being positioned at the floor level face of rotary barrel 3, lifter 20 can upgrade a large amount of relatively clothings at the rear end part that it has big relatively height, and is working the clothing that the rear end part with relatively little height promotes relative a small amount of.Therefore, rotary barrel 3 is maintained at dynamic balance state.So can when steadily rotating, wash all clothings uniformly.
Because in washing process, clothing relatively in a small amount is distributed in the fore-end of the lifter 20 with relatively little height, therefore can not be positioned at clothing the moving towards the rear end part of rotary barrel 3 of the fore-end of lifter 20.
As shown in Figure 3, lifter 20 is arranged round rotary barrel 3, when from the rear end of rotary barrel 3 when its front end extends axially, promptly through the whole length of rotary barrel 3, they separate on circumference each other uniformly.Therefore, lifter 20 can promote all clothings that are contained in the rotary barrel 3 effectively.
The top 21 of each lifter 20 has constant width, and has hole for water spraying 23.Hole for water spraying 23 vertically is arranged as several row.
Each lifter 20 also has in order to spray the structure of washings.That is, each lifter 20 has unlimited hollow structure downwards with the washings of portion's reception within it.In addition, provide opening 27 at rotary barrel 3 with a part that links to each other in the lifter 20.In addition, the bottom 22 of each lifter 20 be open wide to be communicated with connected opening 27.When lifter 20 is positioned at its floor level face, the inside of washings being introduced lifter 20 than low side 22 that can open by coupled opening 27 and its.
Therefore, the washings through introduce each lifter 20 inside in the bottom 22 of the lifter that opens wide of the bottom of rotary barrel 3 spray downwards by the hole for water spraying 23 at the top of rotary barrel 3.Therefore, the washings that mix with washing agent can permeate clothing, thus washing clothes apace.
Although expression in the drawings can partly not provide hole for water spraying in the corresponding end of each lifter 20, to spray washings from the side.
As shown in Figures 4 and 5, thus provide pair of projections 24 that they and lifter are become one in the inside of each lifter 20.Boss 24 is from the internal table at the top 21 of lifter 20 protrusion that faces down.Protruding end at each boss 24 forms threaded connection hole 25.Therefore, can by attachment screw 26 being passed a fully individual connecting hole 25 lifter 20 be installed on the rotary barrel 3 in the outside of rotary barrel 3.
Simultaneously, because because lifter 20 has the height that reduces gradually towards the front end of rotary barrel 3, be positioned at higher horizontal plane according to the fore-end of motion lifter 20 than the rear end part of lifter 20, along with lifter moves to its top from the bottom of rotary barrel 3, warp is introduced the inside of each lifters 20 in the bottom of opening wide 22 of the lifter 20 of the bottom of rotary barrel 3 washings may flow towards the rear end part of lifter 20.As a result, washings relatively in a small amount pass through hole for water spraying 23 sprinklings at the fore-end of lifter 20.On the contrary, washings mainly pass through hole for water spraying 23 sprinklings at the rear end part of lifter 20.
For fear of this phenomenon, each lifter has its inner demarcation strip of arrangement.Figure 4 and 5 hereinafter with reference to the internal structure that has shown a lifter are described this structure.
With reference to Figure 4 and 5, lifter 20 according to the present invention comprises: first and second demarcation strips 31 and 32 are arranged in the inside of lifter 20, with extending transversely when longitudinally spaced from each other.The inside of lifter 20 is separated plate 31 and 32 and is divided into first to the 3rd Room 41 to 43.
Because first demarcation strip 31, when the lifter 20 of association is positioned at the top of rotary barrel 3, is positioned at the washings that first Room 41 of high relatively horizontal plane holds and can flow to second Room 42.Equally, because the washings that second demarcation strip Room 42 32, the second hold can not flow to the 3rd Room 43.
Therefore, the washings that hold in first Room 41 of the front end of lifter 20 only are sprayed at the fore-end of rotary barrel 3, and the washings that hold in second Room 42 at the middle part of lifter 20 only are sprayed at the middle part of rotary barrel.Equally, the washings that hold in the 3rd Room 43 of the rear end part of lifter 20 only are sprayed at the rear end part of rotary barrel 3.
In order to spray the washings of about equivalent from first to the 3rd Room 41 to 43 respectively, arrange first and second demarcation strips 31 and 32 suitably separating the inside of lifter 20, thereby first to the 3rd Room 41 to 43 has the volume that approximately equates.For this reason, first and second demarcation strips 31 and 32 front ends towards lifter 20 tilt, thereby the upper end of each demarcation strip is nearer from the front end of lifter 20 than the lower end of demarcation strip.In addition, first and second demarcation strips 31 have different inclination angles respectively with 32.
According to this arrangement, first and second demarcation strips 31 are divided into three with 32 tops 21 with lifter 20 and have part different but about equal lengths respectively.First and second demarcation strips 31 and 32 than low side the bottom 22 of lifter 20 is divided into three parts, thereby have maximum length corresponding to the part of first Room 41, have minimum length corresponding to the part of the 3rd Room 43.Therefore, first to the 3rd Room 41 to 43 has the volume that approximately equates respectively.
Although lifter is described to have the structure of three chambers 41 to 43 that limited by two dividing plates 31 and 33, can by the lifter internal arrangement more the demarcation strip of more number limit the more chamber of more number.In this case, can come to spray more equably the washings that mix with washing agent by all hole for water sprayings that form in riser top.
Now, will describe by having process according to the tumbling-box washing machine washing clothes of said structure of the present invention.
At first, the user opens door 6, and clothing is put into acclivitous rotary barrel 3.At this moment, the user can need not to reduce its posture and carries out these operations easily.Clothing is distributed in the rotary barrel 3, thereby a large amount of relatively clothings is positioned at the rear end part of rotary barrel 3, and clothing relatively in a small amount is positioned at the fore-end of rotary barrel 3.
Thereafter, user Guan Shangmen 6, and the operation control panel (not shown) is with the running washing machine.Along with the running of washing machine, the water supply start circulation.That is, introduce the washings that are mixed with washing agent through water supply pipe 7 and detergent container 8, thereby fill the bottom of rotary barrel 2.When having supplied with the water yield of wishing accordingly with laundry amounts, the circulation of supplying water is finished.After the water supply circulation was finished, drive motors 5 replaced rotation with rotating shaft 5a with clockwise and counter clockwise direction.Therefore, washed the clothing that holds in the rotary barrel 3.
Although a large amount of relatively clothings is positioned at the rear end part of rotary barrel 3 in the wash cycle process, because it has its rear end part height more higher than its fore-end, lifter 20 can upgrade clothing without a doubt, thus washing clothes effectively.In addition, rotary barrel 3 can rotate under dynamic balance state.
When the rotation of lifter 20 lifting clothings according to rotary barrel, when moving to the horizontal plane that is connected with the top of rotary barrel 3 continuously, clothing is discharged from lifter 20, throws down then, thereby is washed.Simultaneously, introduce the washings that are mixed with washing agent, sprays downwards by the hole for water spraying 23 that the top 21 at lifter 20 provides then by bottom 22 at the lifter of the bottom of rotary barrel 3, thus the immersion clothing.
At this moment, be separated from each other by first and second demarcation strips 31 and 32 in the inside of lifter 20 owing to have first to the 3rd Room 41 to 43 of about equal volume respectively, therefore, washings do not flow to its rear end part from the fore-end of lifter 20.
That is, the washings that are contained in first Room 41 only spray by the hole for water spraying 23 that is formed at lifter 20 fore-ends, and the washings that are contained in second Room 42 only the hole for water spraying 23 of the mid portion by being formed at lifter 20 spray.Equally, be contained in the 3rd Room 43 washings only the hole for water spraying 23 of the rear end part by being formed at lifter 20 spray.
Therefore, washings can spray on the whole length of lifter equably.Thereby the washings that are mixed with washing agent not only are sprayed on the clothing that is positioned at rotary barrel 3 rear ends fully, and fully are sprayed on the clothing that is positioned at rotary barrel 3 middle parts and front end, so the clothing of all parts is washed water and evenly soaks.
After wash cycle is finished, the clean and drying by rinsing and dewatering cycle with the clothing rinsing.Therefore, finish the washing of clothing.In rinse cycle, according to the function and the effect of first and second demarcation strips 31 and 32, all clothings also can be by rinsing equably.
After the washing of clothing was finished, the user opened door 6 once more, and takes out clothing from rotary barrel 3.At this moment, because rotary barrel 3 is inclined upwardly, the user can bend over very much just can carry out these operations easily.
Fig. 6 to 8 represents the structure of lifter according to another embodiment of the present invention respectively.Fig. 6 represents to be arranged in the lip-deep lifter in inside of rotary barrel.Fig. 7 is illustrated in the lifter that its top has waved surface.Fig. 8 represents to be arranged in the demarcation strip of lifter inside.
With reference to Fig. 6 and 7, except its surface is that its top 21 has and comprises and alternately arrange and have respectively the waveform configuration of the groove of arc-shaped surface and projection that lifter 20a has the structure similar to the lifter shown in Fig. 3.
That is, the top 21 of lifter 20a has the incline structure of the height that reduces gradually towards the front end of rotary barrel 3.21a of spine and bottom land 21b also alternately arrange with certain spacing on the top 21 of lifter 21a.In addition, thus on waveform top 21, provide hole for water spraying 23 longitudinally to be arranged as several row.Corresponding hole for water spraying is laterally arranged in each 21a of spine and each bottom land 21b in each row.
Because lifter has the waveform configuration that comprises 21a of spine and bottom land 21b on its top 21, in the space that the inside that the washings of introducing lifter 20a inside rest on lifter 20a is limited by the 21a of spine, and can be not immediately do not flow to its rear end part, and spray continuously towards the bottom of rotary barrel 3 by hole for water spraying 23 from the fore-end of lifter 20a.Therefore, even also have the washings of q.s to spray at the fore-end of lifter 20a.
In addition, because hole for water spraying 23 is longitudinally arranged by row along 21a of spine and bottom land 21b, also less than the washings that are discharged from by the hole for water spraying 23 that is in the horizontal plane higher than the 21a of another spine, flow to the 21a of spine of next level, and pass through hole for water spraying 23 discharges of the 21a of spine of next horizontal plane.
Therefore, washings can not flow to its rear end immediately from the front end of lifter 20a, from rather than mainly only be sprayed at the rear end of lifter 20a.
Because the top 21 of lifter 20a has waveform configuration, to replace in the process of rotation clockwise with counterclockwise, frictional force puts on clothing at rotary barrel 3.
Simultaneously, as shown in Figure 8, lifter 20a can comprise: 21b at the bottom of 21a of circular arc spine on its top 21 and arc-shaped slot, also be included in its inner demarcation strip simultaneously, for example, the demarcation strip 31 and 32 of Figure 4 and 5.
Adopt this structure of lifter 20a, the washings that receive in lifter 20a mainly rest on by the 21a of spine in the space that inside limited of lifter 20a, thereby have slowed down washings flowing towards the reduced levels face portion of lifter 20a.In addition, because first and second demarcation strips 31 and 32, washings no longer flow to the reduced levels face portion of lifter 20a.Therefore, can prevent more effectively that washings from flowing to its rear end part from the fore-end of lifter 20a.
From above-mentioned description obviously as can be known, in tumbling-box washing machine according to an aspect of the present invention, rotary barrel up tilts towards the antetheca of housing, has the structure that level is kept at when it is positioned at the floor level face of rotary barrel its top from each outstanding lifter of the inner peripheral surface of rotary barrel.Therefore,, also may promote clothing without a doubt even when a large amount of relatively clothings is distributed in the rear end part of rotary barrel, thus washing clothes fast and effectively.
Because this structure in tumbling-box washing machine according to the present invention can stably promote clothing by lifter.Therefore, rotary barrel can rotate under the state of dynamic stability.
In addition, clothing can not twine or lump.Therefore, rotary barrel rotates under poised state in dehydration.Also the clothing that is washed need not be untied winding.
In tumbling-box washing machine according to a further aspect in the invention, demarcation strip is arranged in each lifter, limits the chamber that has about equal volume respectively with the inside at lifter.Because this structure, the washings that are mixed with washing agent can spray on the whole length of lifter uniformly.Therefore, the clothing that washs even be distributed in the fore-end of the rotary barrel that is positioned at high relatively horizontal plane apace and effectively becomes possibility.
In tumbling-box washing machine according to a further aspect in the invention, each lifter has waveform configuration at its top.Hole for water spraying in the spine of waveform configuration and bottom land by rows.Only use this structure or use with a plurality of demarcation strips, spray the washings that are mixed with washing agent equably on the whole length of lifter, it is possible simultaneously clothing being applied frictional force.Therefore, can be faster and washing clothes more effectively.
