Simultaneously, it is suitable that drum shaft 6 is formed by stainless steel, although some height of its cost, so that reduce the corrosion resistance that the wearing and tearing/friction of the slidingsurface of watertight seal 12 and drum shaft 6 also keeps drum shaft 6 effectively.

On the surface of pulsator 7, have washing wing 7a, because the clothing bump washing wing 7a that the rotation of cylinder 3 promotes and descends, and in cylinder 3, move forward and backward the frictional force that clothing increases clothing by making.

In this example, the washing wing 7a be provided with at interval with rule preferably forms as one although the interarea of pulsator 7 (that is, the surface) is gone up with it, and nonessential like this.

Simultaneously, washing wing 7a is radially or have at least one inclined plane on the circumferencial direction.

The interarea of pulsator 7 has predetermined curvature, and its external diameter approximately is the 50-80% of cylinder 3 internal diameters.

The maximum height 7a of the washing wing 7a of pulsator 7 is the 5-15% of pulsator external diameter.

In addition, cylinder 3 and bucket 2 preferably are mounted to and make its axis and ground be 10-30 ° of inclination, so that the putting into/take out of clothing, and the raising laundry effect.In addition, the range of tilt angles of 10-30 ° of scope also can prevent the generation of excessive shock.

If the inclination angle surpasses 30 °, make cylinder 3 in the state rotation of too tilting, the clothing of guide roller 3 rear sides tilts, then because the winding of clothing during the laundry performance can descend and rotate excessive shock can take place.

Therefore, consider this point, preferably make the inclination angle of bucket 2 be lower than 30 °.

Simultaneously, cylinder 3 has a plurality of lifter 3a in interior perimeter surface, is used for promoting clothing.The distance " D " of about 30-90mm is arranged between the washing wing of lifter 3a and pulsator 7, be more preferably scope, be used for preventing that clothing from piling up the rotation that stops pulsator 7 and cylinder 3 between lifter 3a and the pulsator 7 at 60mm.

Simultaneously, in the inboard and/or the outside of the front and rear of cylinder 3 autobalance 9 is installed preferably, each autobalance has all been filled liquid, as water or salt solution, and the vibrations when being used for reducing rotation.

For example, autobalance 9 can be installed in the inboard of cylinder 3 front portions and the outside at rear portion respectively, or is installed in the inboard of cylinder 3 front and rears.

In addition, autobalance 9 can have single fluid cavity, or more suitably, two, three or four fluid cavitys on concentric circles separate between the inside and outside fluid cavity, in case the fluid stopping body moves between fluid cavity.

More suitably be that autobalance 9 has the height " H " greater than width " W ", to reduce the vibrations of cylinder 3.

Simultaneously, together with said structure, certainly, between the outer surface of the medial surface of casing 1 upper surface and bucket 2 upsides, also have the pendulum spring 2a that is used for hanging bucket 2, and between the bottom surface of the downside of bucket 2 outer surfaces and casing 1, have the vibrations of baffle plate bucket 2 when being used for stopping rotation.

The operation of various details tumbling-box washing machine.

Cylinder 3 and bucket 2 inclinations with respect to 10-30 ° on its ground, front side can make putting into of clothing and take out more convenient.

Promptly, to/from cylinder 3 put into/when taking out clothing, with the user need be couchant the user or the tumbling-box washing machine of the background technology of the hand of state elongation of bending over different, tumbling-box washing machine of the present invention to/from cylinder 3 put into/when taking out clothing, because the bucket 2 and the cylinder 3 that tilt, make that clothing is easier have been handled.

Except these facilities, tumbling-box washing machine of the present invention also is improved owing to the pulsator 7 that is installed in cylinder 3 inboards makes the laundry performance.

Promptly, owing to only depending on lifter 3a to upgrade and falling clothing and realize washing, there is limitation in the tumbling-box washing machine of background technology at raising laundry aspect of performance, tumbling-box washing machine of the present invention can significantly improve the laundry performance, because tumbling-box washing machine of the present invention is except the bucket 2 and cylinder 3 that tilt, portion also is equipped with pulsator 7 within it, this has also increased the collision of pulsator 7 and clothing beyond the effect of lifter 3a, because the inclination of cylinder 3 and the shape of pulsator 7 make seesawing of clothing more active.

In more detail, heeling condition at bucket 2 and cylinder 3, pulsator axle 8 passes hollow drum shaft 6 and is connected to the pulley 15 at motor rear portion, under the effect of the solenoid 11a and the holddown spring 11c of the arresting stop 11 that is fixedly connected to bucket 2 rear walls, or be applied to below similar under the control of power supply of arresting stop, when piston 11b was placed into (see figure 3) or shifts out the maintenance groove 150a of (see figure 4) pulley 15, pulley 15 was fixed or discharges.This fixing or release of pulley 15 means that pulsator 7 is freely fixed.

In view of the above, because pulsator in when washing or be fixed or freely rotate, has changed the motion of clothing in the cylinder 3, the performance of doing washing just can improve.

Simultaneously, in rotation, piston 11b also can insert among the maintenance groove 150a of pulley 15, and with fixing pulsator 7, or piston 11b can shift out from the maintenance groove 150a of pulley 15, so that pulsator 7 rotates.

In rotation, if solenoid 11a opens piston 11b is shifted out from the maintenance groove 150a of pulley 15, if cylinder 2 rotations then make pulsator 7 also rotate, this moment, the rotation of pulsator 7 was not the stressed rotation that is caused by direct driving force as cylinder.That is, the rotation of pulsator 7 and motor speed are also asynchronous, but the revolving force of cylinder is that the clothing in the cylinder 3 is sent to pulsator 7 on the pulsator 7 owing to being placed on, so it rotates, and almost the speed with cylinder 3 is identical.

Simultaneously, improvement along with the laundry performance, tumbling-box washing machine of the present invention also can be provided with autobalance 9 by the front and rear at cylinder 3, by means of fluid be installed in the counterpoise branch of bucket on 2 balancing drum that comes, thereby reduce in the rotation system's vibrations that the eccentric load by cylinder 3 causes effectively.

Particularly, although tumbling-box washing machine of the present invention because bucket 2 that tilts and cylinder 3 and may have the vibrations bigger than background technology at rear side, the autobalance 9 that cylinder 3 posterior medials or the outside connect can make the vibrations of rear side reduce effectively.

In addition, as previously mentioned, the bucket 2 of inclination also needs the cylinder 3 of bucket in 2 also to tilt, and this makes the be in the suds slurry of injection of cylinder 3 consume still less.

For example, because the cylinder 3 that tilts, slurry tilts on the rear section ground of cylinder 3, and only need place the clothing that concentrates on rear side below the slurry after injecting slurry and just can wash.

Simultaneously, in the assembling of pulley 15, the placement of mating part 15c in drum shaft 6 of pulley 15 can be shortened the total length of tumbling-box washing machine.

Promptly, if the mating part 15c of pulley 15 can not put into the drum shaft 6 of heeling condition, then total length is elongated, will reduce the capacity of tumbling-box washing machine, and the placement of mating part 15c in drum shaft 6 of pulley 15 can be shortened total length, causes making the laundry capacity to improve relatively.

Simultaneously, in washing, the control procedure and the operation of pulley 15 will be described according to the tumbling-box washing machine of first preferred embodiment of the invention.

Rotate the process of washing by cylinder 3 when describing pulsator 7 and remain static below with reference to Fig. 3.

With reference to figure 3, if piston 11b moves forward with among the maintenance groove 150a that is positioned at pulley 15, then pulley 15 can not rotate again, has also fixed the pulsator in the cylinder 3 simultaneously.

At this state, if provide power supply to wash, rotor 4 also rotates the cylinder 3 that links to each other with rotor 4 by axle with regard to owing to rotating with the electrical interaction of stator 5.

In this example, cylinder 3 can alternately rotate on a left side/right under the control of microcomputer (not shown), and pulsator 7 is static.

In view of the above, when the part of clothing bump pulsator 7 and washing wing 7a and since cylinder 3 be tilt travelling forward the time, along with clothing is promoted by a plurality of lifter 3a in the cylinder 3 and by gravity effect decline, thereby realized washing.

Particularly, in washing machine of the present invention, because the central protrusion of washing wing 7a and pulsator 7 promotes the clothing that descends then by lifter 3a and has bigger seesawing than background technology.That is, the inclined surface of washing wing 7a, the interarea bending of pulsator 7, inclination angle or the like has all caused the change of clothing position.

In addition, because cylinder 3 rotates in heeling condition, and pulsator 7 is static, and the motion of speed official post clothing and the washings circulation that exist between cylinder 3 that rotates and static pulsator 7 have form irregular, variation.

In this example, the washings circulation constantly covers the clothing that concentrates on cylinder 3 rear sides in different directions, to impel the even washing of clothing.

That is, be in the suds, the water circulation that is produced by the bump between washings and the pulsator 7, and the collision between clothing and the pulsator have improved the washability and the rinsing ability of clothing in itself.

Different with the front is, with reference to figure 4, with describe when pulley 15 stop to be released the time, pulsator 7 is in the washing under the rotary state.

With reference to figure 4, if provide power supply with mobile piston 11b backward to solenoid 11a, in compression holddown spring 11c, piston 11b shifts out from the maintenance groove 150a of pulley 15, and pulley 15 and pulsator 7 are rotated.

In this state, if provide electric energy to wash, rotor also rotates a cylinder 3 that links to each other with rotor 4 with regard to owing to rotating with the electrical interaction of stator 5.

In this example, as previously mentioned, cylinder 3 alternately rotates on a left side/right with predetermined space, when cylinder 3 rotates, pulsator 7 just in cylinder under the effect of clothing and washings circulation on a left side, or rotate on the direction on the right side.

Operation according to the tumbling-box washing machine of second preferred embodiment of the invention will be described below.

Promptly, owing to only depending on lifter 3a to promote and falling clothing and realize washing, there is limitation in the tumbling-box washing machine of background technology at raising laundry aspect of performance, tumbling-box washing machine of the present invention can significantly improve the laundry performance, because tumbling-box washing machine of the present invention is except the bucket 2 and cylinder 3 that tilt, portion also is equipped with pulsator 7 within it, this has also increased the collision of pulsator 7 and clothing beyond the effect of lifter 3a, because the inclination of cylinder 3 and the shape of pulsator 7 make seesawing of clothing more active.

In more detail, heeling condition at bucket 2 and cylinder 3, pulsator axle 8 passes hollow drum shaft 6 and is connected to the pulley 15 at motor rear portion, under the effect of the solenoid 11a and the holddown spring 11c of the arresting stop 11 that is fixedly connected to bucket 2 rear walls, or be applied to below similar under the control of power supply of arresting stop, when piston 11b was placed into or shifts out the maintenance groove 150a of pulley 15, pulley 15 was fixed or discharges.This fixing or release of pulley 15 means that pulsator 7 is freely fixed.

In rotation, if solenoid 11a opens piston 11b is shifted out from the maintenance groove 150a of pulley 15, if cylinder 2 rotations then make pulsator 7 also rotate, this moment, the rotation of pulsator 7 was not the stressed rotation that is caused by direct driving force as cylinder.That is, the rotation of pulsator 7 and motor speed are also asynchronous, but when cylinder 3 rotations, owing to the clothing that is placed on the pulsator 7, the revolving force of cylinder is sent to pulsator 7 by clothing, so the rotary speed of pulsator is almost identical with cylinder 3.

Simultaneously, in dry run, the pressure of the hot-air that is produced by heater 32 in the drying tube 30 by fan 31 blows along drying tube flows, and introduces the hot air inlet 200 of rear wall upside.

In this example, the cut-out rib 220 of side direction drum rear wall 300 projections has been blocked the hot-air of introducing by the hot air inlet 200 of bucket 2 and has been leaked to the cylinder outside in the rear wall of bucket 2.

In addition, the groove 160 of shape and blocking-up rib 220 shape complementarities has prevented to cut off interference between rib 220 and the tripod in the tripod 16.

Simultaneously, the hot-air of introducing by hot air inlet 200 passes hot-air channel by the hole 300b in cylinder 3 rear walls, and optimizes the inboard that a plurality of hot-air supply holes 710 of arranging supply to cylinder 3 by being in pulsator 7 interareas.

In this example, be positioned at the rib 700 of pulsator 7 on the neighboring of drum rear wall 300 bendings, and the formation part 300a of shape and rib 700 shape complementarities on the drum rear wall 300, cut off air flow effectively, thereby impelled hot-air to concentrate on the middle body of cylinder 3 towards pulsator 7 outsides.

Basically blow also high temperature, the highly humid air of drying clothes along the cylinder axis approximate centre, hot air outlet 210 by bucket 2 underside of forward is discharged, guiding condenser pipe 40, when high temperature, when highly humid air passes through condenser pipe, by the cooling water condensation of supplying with through condensate pipe 60, become low temperature, low humid air.

So along with the flow channel of air by pipe, the air of guiding drying tube 30 circulates again,, and supply to cylinder 3 once more by heater heating wherein.Along with the repetition of such cyclic process, carried out the drying of clothing.

Like this, use in the new drying system, hot-air blows along cylinder 3 axis central authorities, because the air that supplies in the cylinder 3 can deeply arrive cylinder inside, therefore this drying system can make the tumbling-box washing machine of present embodiment improve its drying efficiency and drying property, can make the drying of clothing more even.

Just, hot-air is incorporated into the cylinder 3 from drying tube 30 by the top at bucket 2 rears, the cylinder 3 of flowing through, and discharge by the bottom in bucket 2 the place aheads.Therefore, hot-air has deeply supplied to the inside of cylinder 3 equably, has improved drying efficiency, and drying property.

Different with dryer with the background technology tumbling-box washing machine is, drying tube 30 and bucket 2 be connected wearing and tearing that solved packing ring 20 and the problem of tearing.

In addition, drying tube 30 is accurately symmetrical with upside that being connected of bucket 2 makes packing ring 20 and downside, impels packing ring 20 to absorb the vibrations of bucket 2 equably.

Further, because hot-air is not incorporated in the cylinder 3 through packing ring 20 by bucket 2, different with background technology is to have solved door by the problem of unnecessary heating.

Drying tube 30 and condenser pipe 40 are fixed to bucket 2 makes the coupling part between drying tube 30 and the bucket 2 need not as background technology independently compliant member to be set.

The drying tube 30 that is connected to bucket 2 can also be used to counterpoise, to improve the balance hold facility of bucket.

In addition, effective layout that hot-air channel passes drum rear wall 300 mesopore 300b also can make the flow velocity of the hot-air of introducing cylinder 3 realize maximization, adds the intensity of swift 3 simultaneously.

Simultaneously, improvement along with laundry and drying property, tumbling-box washing machine of the present invention also can be provided with autobalance 9 by the front and rear in cylinder 3 inside, by means of fluid be installed in the counterpoise of bucket on 2 and separate to come balancing drum, thereby effectively reduce in the rotation system's vibrations that the centrifugal load by cylinder 3 causes.

Particularly, although the tumbling-box washing machine of present embodiment because bucket 2 that tilts and cylinder 3 and may have the vibrations bigger than background technology at rear side, the additional autobalance 9 that connects in cylinder 3 posterior medials or the outside has reduced the vibrations of rear side effectively.

Promptly, if the mating part 15c of pulley 15 can not put into the drum shaft 6 of heeling condition, then total length is elongated, will reduce the capacity of tumbling-box washing machine, and the placement of mating part 15c in drum shaft 6 of pulley 15 can be shortened total length, causes the laundry capacity to increase relatively.

Simultaneously, in the washing and drying of tumbling-box washing machine according to the preferred embodiment of the invention, the control procedure and the operation of pulley 15 will be described.

Particularly, in washing machine of the present invention, because the central protrusion of washing wing 7a and pulsator 7 promotes the clothing that descends then by lifter 3a and has bigger seesawing than background technology.That is, the inclined surface of washing wing 7a, the interarea bending of pulsator 7, the inclination angle, or the like all caused the change of clothing position.

In this example, the washings circulation covers the clothing that concentrates on cylinder 3 rear sides again in different directions, to impel the even washing of clothing.

Different with the front is, with reference to Figure 11, with describe when pulley 15 stop to be released the time, pulsator 7 is in washing and the drying under the rotary state.

With reference to Figure 11, if provide power supply with mobile piston 11b backward to solenoid 11a, in compression holddown spring 11c, piston 11b shifts out from the maintenance groove 150a of pulley 15, and pulley 15 and pulsator 7 are rotated.

In this state, if the power supply that washs is provided, rotor also rotates the cylinder 3 that links to each other with rotor 4 by axle with regard to owing to rotating with the electrical interaction of stator 5.

In this example, as previously mentioned, cylinder 3 alternately rotates on a left side/right with predetermined space, when cylinder 3 rotates, pulsator 7 just in cylinder under the interference of clothing and washings circulation on a left side, or rotate on the direction on the right side.

Therefore, when clothing washed by a plurality of lifter 3a liftings of cylinder 3 inboards and by gravity effect decline, because cylinder 3 tilts, the part of clothing had just been run on the pulsator 7 that rotates.

The clothing of running into pulsator 7 travels forward.

Promptly, be similar to the description of front, in this example, because the inclined plane of washing wing 7a, the interarea bending of pulsator 7 and the angle that tilts, tumbling-box washing machine of the present invention has also caused the change of clothing position, thereby is promoted by lifter 3a simply with clothing and the tumbling-box washing machine of the background technology that descends is compared and promoted seesawing of clothing.

That is, even compare for static state with pulsator 7, relative speed difference is little, but it is poor still to have relative velocity between cylinder 3 and pulsator 7, and this has helped the motion of clothing, helps the improvement of washability and rinsing ability.

In brief, tumbling-box washing machine of the present invention can be by keeping big relatively speed difference under the static state at pulsator 7, or under pulsator 7 discharges with the state that rotates freely relatively little speed difference, wash.

In addition, be in the suds, also can wash by being controlled at that pulsator 7 stops or the state that discharging shortens the alternately time cycle of the cylinder 3 of clothing under can not weighing down.

Simultaneously, tumbling-box washing machine of the present invention can or be rotated under its state that rotates freely arbitrarily by control arresting stop 11 under the pulsator 7 fixing states that can not rotate or be dry.

The present invention is not limited to the foregoing description, and various forms of variations and modification all are possible, as long as these variations and modification do not break away from the technology of the present invention scope.

For example, undersized pulsator can be installed on the inner periphery of cylinder 3 rotatably.
