Also be provided with washing leaf 7a on the surface of impeller 7.Washing leaf 7a can increase washings with the frictional force between the washing leaf 7a when washings falls, washings is moved to fore-and-aft direction in cylinder 3.
Here, the interarea of impeller 7 and the washing leaf 7a that is provided with at interval on interarea are preferably integrally formed.Washing leaf 7a to impeller 7 radially or circumferencial direction form one at least with ramp.The interarea of impeller 7 has certain curvature, and the external diameter of impeller is equivalent to 50～80% of cylinder 3 internal diameters.The washing leaf 7a maximum height of impeller 7 is equivalent to 5～15% of impeller external diameter.
The central axis of cylinder 3 and outer bucket 2 is face tilt 10～30 degree relatively.If the angle of inclination surpasses 30 degree, cylinder 3 rotates under the state of wide-angle tilt, and washings can be concentrated to cylinder 3 rear sides during washing, twine mutually,, can produce vibration when dewatering simultaneously so clean result can descend, so the gradient of outer bucket 2 is preferably in below 30 degree.
In addition, a plurality of lifter 3a are set on the inner peripheral surface of cylinder 3, are used for when washing, upwards promoting washings, but should form the distance about 30～90mm between lifter 3a and the impeller 7.Otherwise washings can be clipped between lifter 3a and the impeller 7, and the rotation of impeller 7 and cylinder 3 is restricted.
Forward/rear at cylinder 3 is equipped with autobalance 9, and fluids such as water or salt solution preferably are equipped with in autobalance 9 inside.Autobalance 9 is installed in the inboard, the place ahead of cylinder 3 and the outside, rear of cylinder 3 respectively, perhaps is installed in the place ahead and the rear of cylinder 3 inboards respectively.Autobalance 9 can be the single fluid cell structure, but preferably constitutes concentrically ringed 2 heavy, 3 heavy or 4 heavy fluid cell structures, and inboard fluid chamber and outside fluid chamber separate, and fluid can not flow between each fluid chamber.The height of autobalance 9 (H) more helps reducing the vibration of cylinder 3 during greater than width (W).
In addition, can also the upper inner of casing 1 and outside suspension spring 2a is set between the outer peripheral face top of bucket 2, be used for lifting outer bucket 2; Be provided with damper between the bottom of the outer peripheral face bottom of bucket 2 and casing 1 outside, the vibration that is produced when being used for reducing dehydration.
Roller washing machine of the present invention is because the place ahead of cylinder 3 and outer bucket 2 is to ground inclination 10～30 degree, so can take, put washings easily; Be provided with impeller 7 in cylinder 3 inside, so can improve clean result.That is: existing tumbling-box washing machine, just adopt lifter 3a to promote washings, utilize fallen impulsive force to wash, and roller washing machine of the present invention is owing to be provided with outer bucket 2 and cylinder 3 obliquely, impeller 7 is set in cylinder 3 simultaneously, so when washing, further strengthened the effect of lifter 3a and the percussion between impeller 7 and the washings, make moving forward and backward of washings more active, so clean result significantly improved.
In more detail, outer bucket 2 and cylinder 3 are obliquely installed, and are connected on the drive 15 of motor rear side after impeller axle 8 connects hollow shape drum shaft 6.At this moment, be positioned at the power supply of the restraint device 11 on outer bucket 2 rear walls by control, can make plunger 11b enter under the effect of the solenoid 11a of restraint device 11 and compressing spring 11c in the holddown groove 150a of rondelle drive 15 that (Fig. 3 a) or spin off (Fig. 3 b) from holddown groove 150a, that is: constraint or release drive 15 make impeller 7 fixing or rotations.Therefore, when washing, impeller 7 fixing or rotations make the washings flow regime variation in the cylinder 3, improve scourability.
In addition, when dehydration, control plunger 11b makes in its holddown groove 150a that enters drive 15, makes impeller 7 fixing; Perhaps control plunger 11b, it is spun off from the holddown groove 150a of drive 15, make impeller 7 rotations.
If solenoid 11a closure during dehydration, plunger 11b spins off from the holddown groove 150a of drive 15, also superhigh speed rotation of impeller 7 when cylinder 3 rotates at a high speed, but the rotation of the high speed of the impeller 7 that at this moment carries out not is directly to utilize driving force to force rotation as cylinder.That is: impeller 7 not and the motor synchronous rotation, this is because the washings in the cylinder 3 are deposited in above the impeller 7, the revolving force of cylinder is sent to impeller 7 by washings when cylinder 3 rotations, therefore, impeller 7 just rotates at a high speed with the speed identical with cylinder 3.
In addition, when improving scourability, roller washing machine of the present invention is utilizing fluid to keep the autobalance 9 of cylinder equilibrium and the balance weight that is installed on the outer bucket 2 separately is arranged on the inboard, front and back of cylinder 3, so can more effectively reduce the system vibration that the eccentric weight by cylinder 3 inside causes when dehydration.
Particularly, roller washing machine of the present invention because outer bucket 2 and cylinder 3 tilt, is compared with common roller washing machine, and the vibration of its rear side increases, so at cylinder 3 rear installed inside autobalances 9, can effectively reduce the vibration of rear side.
As mentioned above, because outer bucket 2 and cylinder 3 be obliquely installed, so in cylinder 3, also can wash as usual with a spot of washings.
For example, roller washing machine of the present invention because cylinder 3 is the states that are obliquely installed, washings is concentrated to the rear of the cylinder 3 that tilts, thus only need inject can the washing by soaking thing the washing water yield wash.And, roller washing machine of the present invention, when assembling drive 15, the engaging piece 15c of drive 15 is positioned at drum shaft 6 inside, so the entire length that shortens roller washing machine can be arranged.
The following describes roller washing machine of the present invention when washing, the control procedure of drive 15 and effect thereof.
3a illustrates the process that swing roller 3 washs under impeller 7 stationary states at first, in conjunction with the accompanying drawings.
Shown in Fig. 3 a, if plunger 11b advances and is positioned in the holddown groove 150a of drive 15, drive 15 can not rotate, so impeller 7 can not rotate.In this state, if turn-on power washs, rotor 4 begins rotation, and simultaneously, the cylinder 3 that links to each other with rotor 4 by axle rotates.At this moment, cylinder 3 is rotated according to the control signal of micro computer, and impeller 7 is kept halted state.
Thus, washings is promoted the back by a plurality of lifter 3a of cylinder 3 inside and falls under the effect of gravity, wash, and because cylinder 3 is to tilt, the part of washings when falling with impeller 7 and washing leaf 7a collision, forwards mobile.
Particularly, roller washing machine of the present invention promotes the central protuberance of the fallen washings in back because of collision washing leaf 7a and impeller 7 by lifter 3a, compares with existing roller washing machine, has increased moving forward and backward of washings.That is the interarea curvature of the inclined-plane of washing leaf 7a and impeller 7 and inclination angle etc. is set the position of washings is changed.
In addition, cylinder 3 rotates under the state of inclination, and impeller 7 is fixing, so utilize the washings type of flow and the washings of the speed difference formation variform between the cylinder 3 that rotates and the impeller 7 of fixing to flow to.
At this moment, the washing current play the booster action that washings is evenly cleaned to the washings that concentrates on cylinder 3 rear sides each position dispersion in cylinder again.That is, when washing, utilize current that cause by bump between washings and the impeller 7 and washing force and the rinsability that improves washings by the percussion that bump between washings and the impeller 7 causes greatly.
Different below in conjunction with stating in front of the accompanying drawing 3b explanation, remove the constraint to drive 15, the washing process under impeller 7 free rotation states.
Shown in Fig. 3 b, if solenoid 11a turn-on power, plunger 11b is inhaled into, and makes compressing spring 11c compression, and plunger 11b retreats simultaneously, spins off from the holddown groove 150a of drive 15, and drive 15 can rotate thus, and impeller 7 also becomes rotatable state.
In this state, turn-on power washs, rotor 4 rotations, cylinder 3 rotations simultaneously.
At this moment, as previously mentioned, cylinder 3 is rotated according to the control signal of micro computer, impeller 7 under the effect of cylinder 3, washings and washings to the left or right side rotation.
Therefore, washings is promoted the back by a plurality of lifter 3a of cylinder 3 inside and falls under the effect of gravity, washs.At this moment because cylinder 3 is the states that tilt, so the part of washings when falling with impeller 7 collisions of rotation, the washings that impinges upon impeller 7 is forwards mobile.That is: the interarea curvature of the inclined-plane of washing leaf 7a, the impeller 7 and change in location that factor such as inclination angle causes washings is set, therefore, moving forward and backward of washings is more and more.
Meanwhile, impeller 7 also becomes rotatable state, but is not to be forced to rotation as the speed that cylinder 3 usefulness are stipulated, so have speed difference between the cylinder 3 of rotation and the impeller 7.The washings moving direction and the washings that therefore can form irregular and various form flow to.Though that is: smaller under rotating ratio impeller 7 stationary states of cylinder 3, at this moment also have between cylinder 3 and the impeller 7 and help the relative speed difference that washings flows, and this is helpful to improving washing force and rinsability aspect.
Aforesaid roller washing machine of the present invention can utilize big relatively speed difference to wash under the state of fixing impeller 7, also can utilize relatively little speed difference to wash under the state that impeller 7 rotates freely.
And, fixing or discharge when washing under the state of impeller 7, also can be controlled at ending of cylinder 3 in the short time that washings can not fall to/counter-rotating time and wash.
The present invention can not be limited in the middle of the embodiment, in the scope that does not break away from the technology of the present invention thought various embodiments can be arranged, for example: rotatable small-sized impeller can also be set on the inner peripheral surface of cylinder 3.
