Description
The utility model relates to a kind of agitation wheel for washing machine device that is used for washing machine.
Pulsator washing machine is made motive power by impeller, drives the forward and reverse rotation of clothing, and owing to rubbing power is bigger mutually, the wet wash malleation is on the impeller of rotation at a high speed, so wash degree and damage clothing rate are higher, the washing uniformity is relatively poor, and the winding rate is also bigger.At present, the impeller of pulsator washing machine all is a major diameter spill impeller, be that its shape and structure is roughly the same, and rotating speed is all about 180 rev/mins, its washtub all is again cylindrical and some equally distributed short convex ribs are arranged on inwall, so the improvement of pulsator washing machine clean result depends primarily on the washing current.
The washing current are by the continuous rotating of motor-driven impeller and stop, thereby stir the generation of clothing and the water surface.For the washing current, generally speaking, the time of impeller rotating is long, and then rotation synchronously and do not reach cleaning function between each clothing and between clothing and the water increases clothing on the contrary and increases wearing and tearing with the friction of bucket wall, easily makes the clothing winding; Otherwise the rotating time is too short, can make clothing fail fully to rotate and suitably roll again, do not reach clean result, and wash degree is inhomogeneous.In addition, the overlong time that stops between the rotating can not cause that then the rotating current clash into mutually, and current are strong inadequately, and clean result is poor; The time that stops is too short, and the rotating current clash into fierceness mutually, and clean result is good, but can still exist reversing the current to import because of the inertia force of rotating part, makes motor produce bigger counter electromotive force and fragile motor and bidirectional triode thyristor.In addition, counter-rotating rapidly also brings bigger impulsive force to mechanical part and the mechanical part life-span is reduced.In other words, the improvement of clean result is limited in motor and the machine driven system scope allowed to bear, and forward and reverse driving force and traditional kind of drive are confined to the further improvement of clean result.
The washing machine that addresses the above problem is disclosed in Chinese patent application CN1170059A (on January 14th, 1998), this washing machine adopts two drive units to drive an impeller and the technical scheme that agitators washs by the opposite direction rotation respectively, solved the washing system of single rotary drum washing machine existence and the contradiction of power drive system preferably, made clean result obtain corresponding improvement.But, because its agitators forms the intensity of bump current not as good as impeller, so the raising of clean result also is limited.In addition, the disclosed drive unit of this technical scheme (motor) remains in efficient not high, structure and control system complexity, the shortcoming that manufacturing cost is high.
The purpose of this utility model is: the agitation wheel for washing machine device that a kind of clean result is good, little, simple in structure to motor and mechanical system wearing and tearing, service life is long is provided.
The utility model is to constitute like this: it comprises blade-carrying main impeller (1), tub of washing machine (3) and the motor output shaft (4) that is connected with main impeller (1), on the same plane of cylindrical of main impeller (1), be with a ring-like complementary wave wheel (2) that has the drying blade, one circle driving cog (5) is arranged on the below outside cylinder of main impeller (1), the interior circle of complementary wave wheel (2) is a circle in the step, one circle driving cog (6) is arranged on the imperial palace of the circle circle in the step of complementary wave wheel (2), be fixed with 2～8 axles (7) in the bottom surface of washtub (3), gear (8) all is housed on every axle (7), gear (8) meshes with the driving cog (5) of main impeller (1) and the driving cog (6) of complementary wave wheel (2), is provided with bearing (9) between the bottom surface of complementary wave wheel (2) and washtub (3); Between the lower surface of ring-like complementary wave wheel (2) and bearing (9) bezel ring, (10) is arranged, bezel ring, (10) is taken turns (2) with complementary wave and is connected.
Owing to adopted technique scheme, the utility model compared with prior art, the function of impeller multiplication and optimizing.The line of demarcation of two impellers (promptly reversing the shear line of current) can be set on the preferred positions with not being subjected to structural limitations, like this, when two parallel impellers rotate, the active force equilibrium of bump current mutually, the bump current that produced under equal kinetic energy condition are the strongest, the laundry amounts of being washed flow action is more, and therefore, the version of more single impeller of double wave wheel construction form or impeller and agitators combination is more thoroughly cleaned clothing; Satisfied the washing requirement of general clothing based on the bump current of the fierceness that produces when reversing mutually than the slow-speed of revolution at two impellers, therefore, the impeller working speed has been starkly lower than 180 rev/mins critical value, has significantly reduced the wearing and tearing to clothing; Under two impeller duties, unidirectional rotary water current can not appear all the time, fundamentally got rid of rotary drum washing machine washing uniformity and all relatively poor problem of winding rate.Because transmission structures of the present invention is main impeller double as driving wheel, complementary wave is taken turns the follower of holding concurrently, only can realize the synchronous opposite spin of complementary wave wheel and main impeller in the middle of it with one group of gear, structure is simple especially, reliable, the easy to maintenance and cheap advantage that operates steadily so have, and can reequip on the basis of existing various rotary drum washing machines easily.In addition, this transmission device is always continuous running, does not need the forward and reverse driving of motor, so the detersive efficiency height, realizes expressing with energy-conservation, and has significantly reduced the wearing and tearing of transmission device and the number of starts of motor, thereby prolonged the service life of washing machine.
Accompanying drawing 1 is a structural representation of the present utility model.
