Description

The bucket and the washing machine of impeller backwards rotation in during a kind of the washing

The utility model is a kind of washing machine, more precisely to the improvement of existing washing machine structure.

Existing washing machine, bucket is lived by brake ribbon and unilateral bearing constraint in when washing, the maintenance transfixion.Impeller constantly carries out rotating, the water slug clothing in stirring in the bucket, thus reach the purpose of cleaning clothing, but this washing machine still exists some defective: when 1, washing, bigger to the wearing and tearing of clothing; 2, when clothing more for a long time, the bottom is subjected to water impact strong apart from the nearer clothing of impeller, washes very totally, but wearing and tearing are bigger, and top away from the clothing current of impeller a little less than, be not easy to clean, both some concentrated wear is excessive, some part can not be cleaned again.The problem of above-mentioned existence is the technical problem that people are badly in need of solving.

The purpose of this utility model is to reduce the wearing and tearing of clothing and improve clean uniformity.

In order to achieve the above object, the utility model comprises outer bucket, interior bucket, impeller, transmission and clutch, electrical installation and advance, drainage arrangement, it is characterized in that: a, water discharge dragging device are the two-pass water discharge dragging devices; B, be contained in the gap of adjustment screw on the control lever and ratchet control lever at 10-18mm; Suit one small valve tube in c, the draining valve valve pipe.In the stroke switch SW ₁And connect between the motor and add the one stroke switch SW ₂

In original speed-reducing clutch, clutch is once finished with braking.Speed-reducing clutch generally is in the washing state; Under the washing state, interior bucket is in on-position, and interior bucket can not rotate.During clutch, speed-reducing clutch transfers dewatering state to by the washing state, loosens the braking of internal bucket simultaneously, and bucket is in free state in the circular motion direction in making, and can rotate at a high speed and dewater.

For bucket and the reverse braking of impeller in realizing, bucket should be in free state in the circular motion direction in during washing, impeller drives the current rotation, the water impact clothing also drives its rotation, under the frictional force effect, the rotation of bucket always lagged behind impeller in current and clothing drove again, because impeller frequently commutates, when impeller begins to reverse, interior bucket is still also just changeing, thereby the backwards rotation of bucket and impeller in realizing, in the realizing barrel of purpose with the backwards rotation of impeller, the braking of speed-reducing clutch separates with clutch to be carried out.Therefore, adopt the two-pass water discharge dragging device, make the speed-reducing clutch control lever that two strokes be arranged, to realize separating of braking and two actions of clutch.For realizing that braking separates with clutch, the gap that also needs the speed-reducing clutch control lever to be adjusted screw and ratchet control lever changes 10-18mm into by former 1-3mm, and removes the unilateral bearing in the former speed-reducing clutch.Cause leaking for prevent that draining valve from being drawn back when washing, in the valve pipe of draining valve, set up a small valve tube.During washing, the two-pass water discharge dragging device is braked first stroke, makes brake ribbon loosening, loosens the constraint of internal bucket, and the ratchet control lever is motionless, and speed-reducing clutch is by the transmission of washing type of belt drive, the backwards rotation of bucket and impeller in can realizing.When the two-pass tractor rotated second stroke, the ratchet control lever made ratchet loosen ratchet adjusting rotation under the screw promotion, the clutch tensioned, and speed-reducing clutch is realized the rotation of dewatering by the transmission of dehydration type of belt drive.

1, outer bung; 2, gimbal; 3, interior bucket; 4, outer bucket; 5, impeller; 6, wash shaft; 7, speed-reducing clutch; 8, brake ribbon; 9, dehydrating shaft; 10, tie-rod; 11, planetary gear; 12, centre wheel; 13, clutch spring; 14, ratchet; 15, ratchet; 16, belt pulley; 17, belt; 18, heat radiation belt pulley; 19, main shaft; 20, motor; 21, ratchet control lever; 22, retracting spring; 23, back-moving spring; 24, adjust screw; 25, control lever; 26, water discharge dragging device; 27, valve pipe; 28, small valve tube; 29, extension spring; 30, power shaft; H-adjusts screw and ratchet control lever gap.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, impeller 5 and interior bucket 3 backwards rotation need to realize that braking separates with two actions of clutch in order to realize washing.This requires water discharge dragging device 26 that two walking journeys are correspondingly arranged, and therefore, is used instead by a former stroke tractor and to be two-pass water discharge dragging device 26.For realizing two walking journeys, on former one-stroke water discharge dragging device circuit base, increase a travel switch SW ₂For realizing separating of control and clutch, will adjust screw 24 and ratchet control lever 21 gap H and change 10-18mm into by 1-3mm.And remove unilateral bearing in the former speed-reducing clutch 7.Cause leaking for prevent that draining valve from being drawn back when washing, in its valve pipe 27 inner chambers, install a small valve tube 28 additional.After water discharge dragging device 26 first strokes finished, A was of a size of 0.3-1.8mm among Fig. 4.In second stroke (about 13mm) of water discharge dragging device, small valve tube 28 just drives valve pipe 27 and draws back the valve plug draining.

During washing, water discharge dragging device 26 action first strokes (about 13mm) drive control lever 25 and overcome the rotation of back-moving spring 23 spring forces, and the brake ribbon 8B that links to each other with control lever 25 end makes brake ribbon 8 loose to left movement, and bucket 3 is in free state in making.Because behind first stroke, gap H still exists, and ratchet control lever 21 keeps motionless.Because interior bucket 3 is in free state, so can realize interior bucket 3 and impeller 5 backwards rotation.

During dehydration, on the first stroke basis, water discharge dragging device 26 action second stroke (about 13mm) drive control lever 25 and are rotated further, and brake ribbon 8 still loosens, control lever 25 overcomes the rotation of retracting spring 22 spring forces by adjusting screw 24 drive ratchet control levers 21, make ratchet 14 loosen ratchet 15, resetted, make power shaft 30 and dehydrating shaft 9 interlocks by 15 big clutch springs 13 of ratchet, interior bucket 3 high speed rotating have realized dehydration.
