In addition, the relative ground of central axis of described cylinder 3 and the outer bucket 2 10-30 degree that preferably tilts.
This is the scope that can conveniently put into or can prevent when increasing clean result and dehydration when taking out washings excessive vibrations.
If described angle of inclination surpasses 30 degree, cylinder 3 rotates under the state of wide-angle tilt, and washings will be concentrated to cylinder 3 rear sides during washing, and mutual the intersection twines, and also can vibrate when therefore dewatering when clean result descends.
Consider the problems referred to above, the gradient of described outer bucket 2 is best below 30 degree.In addition, described cylinder 3 inner peripheral surfaces upwards promote several lifters 3a of washings when being provided with washing, form about spacing of about 30 to 90mm between described lifter 3a and the impeller 7.
In order to prevent because of washings is clipped between lifter 3a and the impeller 7, the restrained phenomenon of rotation of impeller 7 and cylinder 3 appears, need guarantee the spacing between them.
And, when dehydration,, be preferably in the autobalance 9 that cylinder 3 front/rear sides are equipped with fluids such as water or salt solution are housed for reducing vibration.
At this moment described autobalance 9 can constitute the single fluid cell structure, but preferably constitutes concentrically ringed 2 heavy or 3 heavy or 4 heavy fluid chamber's structures, and inboard fluid chamber and outside fluid chamber are separated, and does not allow fluid flow between each fluid chamber.

Between the inboard and outer bucket 2 outer peripheral face upper side of described casing 1 upper side, also can be set to the sling extension spring 2a of outer bucket 2, outer barrel 2 damper 2b that vibrates of generation when promising reduction dehydration is set between bucket 2 outer peripheral face lower side and casing 1 bottom surfaces described outside.
Operation principle to roller washing machine of the present invention is described as follows:
Roller washing machine of the present invention, the front side of bucket 2 is provided with ground inclination 10-30 degree beyond the cylinder 3, so can put into and take out washings easily.
Because being obliquely installed of outer bucket 2 and cylinder 3 can be easy to when putting into and take out washings, provides convenience to the user thus.
Because roller washing machine of the present invention is provided with impeller 7 in cylinder 3 inside, so can improve scourability.
Promptly, structure with the front roll rotation, only adopt lifter 3a to promote to leave the mode of getting off behind the washings and wash, be restricted aspect the raising scourability, but roller washing machine of the present invention is because the state that tilts is provided with impeller 7 when outer bucket 2 and cylinder 3 are set in cylinder 3, so when washing, further strengthen the effect of lifter 3a and the percussion between impeller 7 and the washings, and because of cylinder 3 inclination and impeller 7 shapes, the front and back of washings are flowed more active, so scourability significantly improves.
In more detail, outer bucket 2 and cylinder 3 are obliquely installed, after connecting hollow shape drum shaft 6, impeller axle 8 is connected on the drive 15 of motor rear side, because restraint device 11 power supplys on outer bucket 2 rear wall parts etc. are fixed in control in this state, plunger 11b maintains the state in the holddown groove 150a that enters rondelle drive 15 under the effect of the solenoid 11a of restraint device 11 and compression spring 11c or spins off from holddown groove 150a, and is fixing or discharge drive 15.That is the fixedly rotation of impeller 7 or discharge rotating freely of impeller 7.
Thus, when washing, impeller 7 so the washings flow regime in the cylinder 3 can be diversified, thereby improves scourability as fixing or rotatable state.
In addition, when dehydration, control plunger 11b enters in the drive 15 holddown groove 150a, makes impeller 7 be in the state that is fixed; Perhaps control plunger 11b, spin off, make impeller 7 be in the state of rotation from the holddown groove 150a of drive 15.
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 not the same pressure rotation that directly utilizes driving force to carry out of the high speed of impeller 7 rotation at this moment with cylinder.Promptly, impeller 7 does not rotate synchronously with motor speed, but because the washings in the cylinder 3 is deposited in above the impeller 7, the revolving force of cylinder sends impeller 7 to by washings when cylinder 3 rotations, and described thus impeller 7 just rotates with cylinder 3 akin speed.
In addition, when improving described scourability, roller washing machine of the present invention utilizes the fluid autobalance 9 of keeping the cylinder equilibrium and the balance weight that is arranged on the outer bucket 2 to separate the inboard, front and back that is arranged on cylinder 3, so can more effectively reduce system's vibrations that the eccentric weight by cylinder 3 inside causes when dehydration.
Especially, roller washing machine of the present invention, because outer bucket 2 and cylinder 3 tilt, the vibration of comparing rear side with the normal drum washing machine increases, so at cylinder 3 rear installed inside autobalances 9, can effectively reduce the vibration of rear side.
As mentioned above, because the state setting of described outer bucket 2 to tilt, the cylinder 3 that is positioned at described outer bucket 2 inboards also is in the state of inclination, so just can wash normally with a spot of washings in described cylinder 3 inside.
For example, roller washing machine of the present invention, because described cylinder 3 is the states that are obliquely installed, washings is concentrated to cylinder 3 rear sides of described inclination, so only inject the washings of the washings that can soak cylinder 3 rear sides, normally washs and gets final product.
And, roller washing machine of the present invention, when assembling drive 15, the engaging piece 15c of drive 15 is housed in drum shaft 6 inside, so the effect that shortens the roller washing machine whole height can be arranged.
Promptly, under the state that tilts, if the engaging piece 15c of drive 15 can not be housed in drum shaft 6 inside, whole height prolongs, the shortcoming that exists the capacity of roller washing machine to dwindle, but roller washing machine of the present invention is accommodated the engaging piece 15c of drive 15 6 li of drum shafts, and whole height shortens, so realize that washing capacity increases relatively.
The following describes the control procedure and the effect thereof of the drive 15 of roller washing machine of the present invention in carrying out washing process.
At first, the 3a explanation is connected power supply under described impeller 7 locked states in conjunction with the accompanying drawings, and washing machine starts the process that enters washing procedure.
Shown in Fig. 3 a, when plunger 11b was positioned in the holddown groove 150a of drive 15, drive 15 can not be rotated by pining down of holddown groove 150a, and impeller 7 was fixed in the cylinder 3 and can not rotates this moment.
Described cylinder 3 is accepted the control signal of micro computer (not shown) and is pressed the setting cycle left rotation and right rotation, and described impeller 7 maintains halted state.
Thus, washings is promoted the back by a plurality of lifter 3a of described cylinder 3 inside and falls under the effect of gravity, realize washing process, because described cylinder 3 is the states that tilt, the washing leaf 7a collision of the part of described washings when falling and on described impeller 7 and the described impeller 7, washings moves to cylinder the place ahead.
In the roller washing machine, leave the washings that gets off protrusion central portion after promoting by lifter 3a because of collision washing leaf 7a and impeller 7, that is, the inclined-plane of washing leaf 7a and the surface curvature of impeller 7 and inclination is set make the aggravation of flowing before and after the washings cause the change in location of washings.
In addition, described cylinder 3 rotates under the state that tilts, and described impeller 7 is in the state of locking, so the speed difference between the cylinder 3 of rotation and the fixing impeller 7 forms the washings of irregular and variform and flowing of washing current.
At this moment, the washing current make the washings that concentrates on cylinder 3 rear sides each position dispersion in cylinder again washings realize the booster action that evenly cleans.
During washing, clash into the impact that causes between the current that bump causes between washings and the impeller 7 and washings and the impeller 7, improved the washability and the rinsing ability of washings greatly.
Below in conjunction with the washing process of accompanying drawing 3b explanation impeller 7 under free rotation state.
Shown in Fig. 3 b, solenoid 11a connects power supply, and plunger 11b is inhaled into, plunger 11b moves when compression spring 11c is compressed backward, plunger 11b breaks away from from holddown groove 150a from drive 15, and drive 15 can rotate thus, and impeller 7 also is in rotatable state.
Connect the power initiation washing machine this moment, rotor 4 is rotating under electromagnetic interaction with between the described stator 5, with 3 rotations of 4 cylinders that are connected of described rotor.
At this moment, described cylinder 3 is pressed the setting cycle left rotation and right rotation as the aforementioned control signal of accepting micro computer (not shown), and described impeller 7 is subjected to because of the washings of described cylinder 3 and cylinder internal flow and the influence of washings, impeller 7 left rotation and right rotation.
Therefore, washings is promoted the back by a plurality of lifter 3a of described cylinder 3 inside and leaves under the effect of gravity down, washs.At this moment, because described cylinder 3 is the states that tilt, so the part of described washings impeller 7 with rotation when falling collides.
In addition, the washings that impinges upon described impeller 7 moves to cylinder the place ahead.
Promptly, at this moment with aforementioned the same, roller washing machine of the present invention, the inclined-plane of washing leaf 7a, the interarea curvature of impeller 7 and the inclination angle is set, washings promotes the simple fallen benchmark in back and compares the change in location that the aggravation of flowing before and after the washings causes washings with in the past the device 3a that is raised.
Meanwhile, described impeller 7 also becomes rotatable state, but and the same speed in accordance with regulations of the cylinder 3 of getting along well are forced to rotation, so have speed difference between the cylinder 3 of rotation and the impeller 7, the washings that forms irregular and various form flows and washs current.
That is, impeller 7 rotatable states are littler than the relative speed difference of impeller 7 stationary states, but the relative speed difference that at this moment also exists auxiliary washings to flow between cylinder 3 and the impeller 7, and this is helpful to improving washing intensity and rinsing intensity aspect.
For example, described roller washing machine of the present invention utilizes big relatively speed difference to wash under the state of fixing impeller 7, perhaps utilizes relatively little speed difference to wash under the state of the release that impeller 7 rotates freely.
And, during washing,, also can be controlled at the forward of described cylinder 3/counter-rotating time in the short time that washings can not fall and wash fixing or discharge under the state of described impeller 7.
It is worthy of note that protection scope of the present invention is not limited to the above-mentioned specific embodiment, for example, can also built-in rotatable small-sized impeller on cylinder 3 inner peripheral surfaces.According to basic fundamental design of the present invention, those of ordinary skills need not can associate some other specific embodiment through creative work, and these all belong to protection scope of the present invention.
