Description
Technical field
The utility model relates to a kind of two-power washing machine driving mechanism and uses water-tight device.
Background technology
Washing machine is to make the machine of removing attached to the spot on the washings through chemical breakdown effect and mechanical shock effect.Recently, a kind of two-power washing machine is just receiving consumer's favor.So-called two-power washing machine is exactly when washing procedure, and the direction of rotation of impeller and interior bucket is opposite, and when dehydration procedure, impeller is identical with the direction of rotation of interior bucket.Like this, washing machine is when washing, and impeller and interior bucket are simulated the effect of rubbing, thereby not only can also reduce the winding and the wearing and tearing of washings the strong dirt-removing while; When dehydration, can dry washings fast again.
Various problems such as present two-power washing machine driving mechanism ubiquity assembly technology is complicated, manufacturing cost is high, service life is short also are the technical barriers that two-power washing machine driving mechanism manufacturing enterprise needs to be resolved hurrily always.
Number of patent application is that 201020268098.6 Chinese utility model patent discloses a kind of two decelerating clutch of washing machine that drives, and can be applied in two driving washing machines, promptly in the two-power washing machine.Specifically comprise impeller axle, dehydrating shaft, block bearing, installing plate, drive plate, connection bearing, braked wheel, deceleration train, clutch shaft, Engaging-and-disengaging bearing, lower house, power shaft, belt pulley, arrangement of clutch and brake apparatus; Dehydrating shaft is fixedly supported upon on the installing plate through block bearing; Dehydrating shaft is connected with drive plate, and connection bearing is connected with braked wheel, and the deceleration train is installed in braked wheel inside; Braked wheel and clutch shaft are rigidly connected; Clutch shaft is fixedly supported upon on the lower house through Engaging-and-disengaging bearing, and power shaft is installed in the clutch shaft, and power shaft one end is connected with belt pulley; The other end is connected with the deceleration train, between dehydrating shaft and the drive plate for being rigidly connected.During the washing operating mode, motor power passes to power shaft by belt pulley, passes to impeller axle and dehydrating shaft to the power of fixed speed ratio and rotation direction respectively through the deceleration train; During dehydration condition; Arrangement of clutch and brake apparatus performance function, motor power passes to power shaft through belt pulley, passes to clutch shaft again; Because deceleration train 8 has a part to be packed on the clutch shaft; Pass to drive plate through this connection power through the deceleration train, pass to rigidly connected with it dehydrating shaft again, finally give washing machine inner tub transmission of power.
There is multinomial deficiency in the said two decelerating clutch of washing machine structures that drive of this patent: adopt between dehydrating shaft and the drive plate at first that rigidly connected structure is difficult to assemble, production efficiency is low; Cause its assembling scrappage high because dehydrating shaft and drive plate adopt to be rigidly connected simultaneously, extremely be not suitable for sizable application aborning; Secondly, two waterproof, leakproof wet goods poor-performings that drive decelerating clutch of washing machine of this structure, thus cause problems such as brake inefficacy, motor inefficacy, also can produce security incident when serious; And two driving decelerating clutch of washing machine assembly technologies of this structure are complicated, scrappage is high, friction is worn the deceleration train because its upper planet wheel cover plate and lower planetary gear cover plate take place relatively in running; The train that causes slowing down is short service life; In case the deceleration train is scrapped; Will cause most of part of this pair driving decelerating clutch of washing machine all can scrap; Therefore far can not meet each item performance requirement of two-power washing machine related standards, propose a kind of function admirable, cost two-power washing machine driving mechanism low, long service life remains this area needs the urgent problem that solves its driving mechanism.
