Below, the effect of clutch apparatus of the automatic washing machine of said structure is described.
At first, clutch motor 6 is in the closed condition of not connecting power supply before the washing beginning, and as Fig. 2 b and shown in Figure 3, shaft coupling 15 is in the decline state.
At this moment, but mover 9 is positioned at the groove that inclined plane 801 is arranged 800 of lever 8, and shaft coupling 15 is positioned at the setting point.
This moment is as clutch motor 6 energisings, power supply clutch motor 6 is opened, the driving force of above-mentioned clutch motor 6 is transmitted on the cam 600 by driving shaft, because the connecting rod 17 of the bar connecting axle 601 that the rotatablely moving of above-mentioned cam 600 is connected cam just can move to clutch motor 6, is guided the guiding lever 8 of lever 30 to pull to clutch motor 6 thereupon.
At this moment, the back-moving spring 14 of above-mentioned guiding lever 30 rearward end setting prolongs.
On the one hand, but the mover 9 that contacts the inclined plane 801 of above-mentioned lever 8 during cam 600 rotation is tilted face 801 drops, and shown in Fig. 2 a and Fig. 4 a, but mover 9 is positioned at tabular surface 802 bottoms of lever 8 when cam 600 is positioned at holding point.
Like this, cam 600 to holding point rotation and the lever 8 followed thereupon to the moving of clutch motor one side, but mover 9 descends thereupon, but mover 9 compression buffer springs 11, thereupon, but because the moving of above-mentioned mover 9, the piston 10 of liftable setting begins to descend in the guiding groove.
Because the decline of above-mentioned piston 10, the movable rod 12 that is connected above-mentioned piston 10 with hinge is that anticlockwise rotation on the drawing is done at the center with any steady pin 12b of the middle part of the perforation support rack 220 of the shaft joint blocking-up 22 that is fixed on cartridge housing 20 bottoms.
And movable rod 12 is when rotating in a counter-clockwise direction on the drawing of center with steady pin 12b, and the front end of above-mentioned movable rod 12 contacts with the bottom surfaces of shaft coupling 152 above-mentioned shaft coupling 15 is promoted along dehydration axial axis top.
Thereupon, finish powershift to washing mode.The gear 151 that forms on above-mentioned shaft coupling 15 upper ends shown in Fig. 2 a, and is fixedly coupled device blocking-up 22 gears that have and matches on the bottom surfaces of above-mentioned cartridge housing 20.
In addition, when the gear 151 of above-mentioned shaft coupling 15 matched with the gear of connector blocking-up 22, then above-mentioned shaft coupling 15 broke away from from assembling connector assembly 16, only rotates wash shaft 4 when rotor 7b rotates.
That is to say, during above-mentioned shaft coupling 15 is in sawtooth on dehydrating shaft 5 outer peripheral faces cooperates state, mismatch with the sawtooth 161b of the female connector assembly 16b upper end that cooperates on the wash shaft, so the rotary power of rotor 7b only is transmitted to bobbing machine 3 by wash shaft 4.
When the gear 151 of above-mentioned shaft coupling 15 was in the state that cooperates with the gear of connector blocking-up 22, the rotation of shaft coupling 15 was not connected the gear institute overslaugh of device blocking-up 22.
Like this, switch to the clutch motor 6 maintenance closing state that washing mode washs.
The course of action of the clutch apparatus during below to dehydration describes.
Shown in Fig. 2 a, after washing machine carries out washing process, require power pathway in order to dewater to dehydration mode, carry power supply power to clutch motor, above-mentioned clutch motor is driven, and cam begins rotation.
Like this, 600 rotations of the cam of clutch motor 6 are moved to dehydration location, lever 8 because of the restoring force of back-moving spring 14 away from clutch motor 6.
At this moment, but under washing mode contact at the mover 9 of the tabular surface 802 of lever 8 shown in Fig. 2 b, reply at lever 8 and to be positioned on the position that is on the groove 800 that lever 8 possesses inclined plane 801.
But when rising with the mover 9 that lever 8 moves, the compression stress that is added on the buffer spring 11 is alleviated, and thereupon, but the above-mentioned piston 10 that can rise along with the guiding groove 900 of mover 9 begins to rise.
With the rising of above-mentioned piston 10, the steady pin 12b that the movable rod 12 that is connected above-mentioned piston 10 with hinge supports hand frame 220 to be provided with the perforation of the shaft joint blocking-up 22 that is fixed on cartridge housing 20 bottoms is that the center is done on drawing and turned clockwise.
Like this, movable rod 12 is when rotating in a clockwise direction on the drawing of center with steady pin 12b, has then removed the front end of above-mentioned movable rod 12 and has supported the power that shaft coupling 15 pushes away along dehydration axial axis top.
Along with to the removing of the holding power of the movable rod 12 of shaft coupling 15, the gear 151 of above-mentioned shaft coupling 15 is spun off by the gear 221 of connector blocking-up 22.
And, descend fully as shaft coupling 15, shown in Fig. 2 b, sawtooth 150a, the 150b of above-mentioned shaft coupling 15 inner peripheral surfaces respectively be combined in wash shaft on female connector assembly 16b upper end outer peripheral face on sawtooth 161b and the sawtooth of dehydrating shaft 5 bottoms cooperate separately, thereby wash shaft 4 and dewater and 5 can rotate at a high speed and dewater when rotor 7b rotates at a high speed thereupon.
At this moment, sawtooth 150b with the meshing part of female connector assembly 16b among sawtooth 150a, the 150b that forms on the inner peripheral surface of above-mentioned shaft coupling 15 has bigger modulus, and the end portion that is positioned at the sawtooth 150b of lower side is processed into circle and makes with the engagement of the sawtooth 161b of above-mentioned female connector assembly 16b and separate and be more prone to.
But there is following problem in so existing clutch apparatus.
When switching to dehydration mode, recover to the right from drawing with clutch motor 6 drive link 17, and, interlock descends shaft coupling 15 with the restoring force of the decline compression spring 40 of movable rod 12 therewith, thereby, the sawtooth of the sawtooth 150b of shaft coupling 15 bottoms and female connector assembly 16b matches, and makes the rotating shaft rotation.
At this moment, the groove 162a of outconnector assembly 16a inboard is provided with the soft washer 18 that prevents noise, because the bottom surface of each projecting rib 183a, 183b of the support of the shaft coupling that above-mentioned soft washer 18 forms above part forms the tabular surface structure, the unfavorable shortcoming of performance that reduces noise is arranged.
Particularly, to the powershift of dehydration mode the time, shaft coupling 15 is staggered relative with female connector assembly 16b, at this moment, when beginning the dehydration action, because the rotation shaft coupling 15 of rotor 7b and the staggered elimination of female connector assembly 16b, simultaneously because during restoring force shaft coupling powerful decline of 15 moments of compression spring 40, become tabular surface because form the bottom surface of protruding ridge 183a, 183b above the soft washer of existing structure 18, so and the change of the contact area of the lower surface of shaft coupling 15 is big, thereby noise that generation also will be bigger.
This shows that above-mentioned existing automatic washing machine still has many defectives with the noise minimizing soft washer structure of clutch, and demands urgently further being improved.
In order to solve existing automatic washing machine reduces the existence of soft washer structure with the noise of clutch defective, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, therefore how to found a kind of automatic washing machine that has that volume is little, cost is low concurrently and can have comprehensive adjustment function when using and reduce the soft washer structure, just become the current industry utmost point to need improved target with the noise of clutch.
