Preferably, in the present embodiment, shown in Figure 3, be provided with the Compress Spring 330 that resets between non-magnetic 311 and rotor case 121, when solenoid 323 energising, magnetic conduction steel ring 312 is subject to electromagnetic repulsive force, drives to be integrated non-magnetic 311 of being connected with it and to endwisely slip downwards along power shaft body 221a outer wall, makes the latch 314 of non-magnetic 311 bottoms and draw-in groove 124 engagement connections of rotor case 121; When solenoid 323 outage, electromagnetic repulsive force disappears, and non-magnetic 311 Compress Spring 330 that is subject to resetting is to the elastic reset power of its generation, and non-magnetic 311 upwards endwisely slips and reset along power shaft body 221a outer wall, with rotor case 121, break away from, and in the on-fixed state.Specifically preferably, in the present embodiment, power shaft body 221a is installed with jump ring 660 near the end of rotor case 121, place spring retainer 340 on jump ring 660, non-magnetic 311 bottoms are provided with spring resettlement groove 350, Compress Spring 330 1 ends that reset are arranged in this spring resettlement groove 350, and the other end is arranged in spring retainer 340.
The course of work of present embodiment is as follows:
When washing machine enters the washing operating mode, solenoid 323 outages, the elastic reset power of Compress Spring 330 to its generation is subject to for non-magnetic 311 resetting, make clutch gear ring 310 and rotor case 121 break away from, and in the on-fixed state, now, rotor assembly 120 drives sun gear 510 synchronous rotaries by driving force by power shaft 211, because sun gear 51 and planetary gear 520 are connected with a joggle, planetary gear 520 is connected with a joggle with ring gear 530 again, therefore planetary gear 520 carries out rotation and revolution power simultaneously, its revolution power is delivered to output shaft 212 by the planet carrier 550 be fixedly connected with it, thereby output shaft 212 drives the washing execution unit rotation of washing machine, its rotating speed is less than the rotary speed of rotor assembly 120, therewith synchronously, the rotation power of planetary gear 520 is delivered on output sleeve 222 by ring gear 530, thereby output sleeve 222 drives the dehydration execution unit rotation of washing machine, it turns to the switched in opposite with output shaft 212, its rotating speed is less than the rotary speed of rotor assembly 120 equally, thereby realize washing function, therefore driving mechanism for washing machine provided by the invention can be adjusted according to the variation of wash load the rotating speed of output shaft, effectively reduce washing work energy consumption, can alleviate or eliminate being washed the damage of clothing simultaneously, and the burnout failure that the motor that can avoid washing machine causes because of overload,
When washing machine enters dehydration condition, solenoid 323 energisings, magnetic conduction steel ring 312 is subject to electromagnetic repulsive force, drive and to be integrated non-magnetic 311 of being connected with it and to endwisely slip downwards along power shaft body 221a outer wall, make draw-in groove 124 engagement connections of latch 314 with the rotor case 121 of non-magnetic 311 bottoms, to input axle sleeve 221 is connected to one with rotor case 121, due to output sleeve 222 with the input axle sleeve 221 for being fixedly connected with relation, power shaft 211 is fixedly connected with rotor case 121 equally, thereby make transmission component 200 become rigid unitary, no longer carry out deceleration transmission, but together carry out synchronized in the same way rotation with rotor assembly 120, thereby realize dehydrating function.
In driving mechanism for washing machine of the present invention, in order to prevent axial float or displacement or installation, can install in the applicable position of power shaft, output shaft, input axle sleeve or output sleeve a plurality of jump rings and other identical functions parts additional; For the ease of installing and load-bearing, can install in the applicable position of power shaft, output shaft, input axle sleeve or output sleeve pad and other identical functions parts additional; For normal delivery and the installation that meets drive connection of the present invention, can a plurality of oiliness bearings and a plurality of ball bearing be set at different parts, as a plurality of oiliness bearings (Fig. 1 and Fig. 3 all illustrate) are set between output shaft and output sleeve, between installing plate and output sleeve and between stator mounting disc and input axle sleeve, a plurality of ball bearings are being set, more specifically, described ball bearing can be deep groove ball bearing.In order to prevent that washings from entering in planet circular system and motor along output shaft, output sleeve and installing plate, little water seal is set between output shaft and output sleeve, large water seal is set between output sleeve and installing plate.Preferably, in order to realize the damping noise abatement when working, install the beam that plastic material or elastomeric material are prepared from additional between each build-up member, and under the condition that meets installation strength or correlation function, will be as installing plate etc., adopt casting aluminium material to be prepared from, to reduce the component processing manufacturing cost, and in order to improve the intensity of each parts, at concrete parts, as the reinforcement of difformity and quantity is set on installing plate, stator installing plate and rotor case.
Because each parts such as above-described jump ring, pad, oiliness bearing, ball bearing, large water seal, little water seal, damping noise abatement part and reinforcement sheet are those skilled in the art's customary means, so any change of structurally making for above part all is interpreted as not possessing novelty with respect to this patent.
The embodiment of the invention also discloses a kind of washing machine, comprise washing and dehydration execution unit, and driving mechanism for washing machine, wherein, described driving mechanism for washing machine adopts driving mechanism for washing machine as above, can adjust according to the variation of wash load the rotating speed of output shaft, and washing work energy consumption is low, can effectively avoid motor because burnout failure occurs overload, and simple in structure, compact, volume is little, control flexibly accurately.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and in the situation that do not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, therefore is intended to include in the present invention dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limit related claim.
In addition, be to be understood that, although this specification is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, and the technical scheme in each embodiment also can, through appropriate combination, form other embodiments that it will be appreciated by those skilled in the art that.
