Description

Washing machine

The utility model relates to the improvement of washing machine structure and serviceability, belongs to the textile washing apparatus technology.

Existing impeller-type cover bucket automatic washing machine is dehydration barrel of suit in its cylinder bucket (or claiming steel ladle), and this bucket can rotate around fixed axis, and position and height can not change.Have some apopores on dehydration bucket bottom and the sidewall, so that dehydration barrel communicates with the cylinder bucket, dehydration bucket bottom is equipped with impeller, the washing of clothing, and rinsing and dehydration are all carried out in dehydration barrel.During washing, impeller rotates around fixed axis, makes cleaning solution form the swirl shape torrent of certain position in the cylinder bucket, and constantly clothing is washed away in rolling, finishes washing.During dehydration, because clothing remains in the dehydration barrel, and the no height change of this bucket, so must emit earlier cleaning solution in the cylinder bucket, only take advantage of clothing after, dehydration barrel is High Rotation Speed again, finishes dehydration.More than argumentation to some extent in the books such as " operation principle of washing machine and maintenance techniques " published in December, 1987 of " use of washing machine and the maintenance " of publishing in Science and Technology of Shanghai publishing house in January, 1989 and New Age Press.By patent retrieval with consult interrelated data as can be known: so far also invention adopt planetary impeller to wash; And when dehydration keeps dried up of clothing holder cleaning solution motionless washing machine in washing tube automatically.

The purpose of this utility model will be invented the washing machine with above-mentioned functions exactly.

The utility model is equipped with the liftable that is driven by elevating mechanism in the washing tank bucket, and the short bucket of lifting and dehydration is arranged.During washing, short bucket places cylinder bucket bottom, and during dehydration, short bucket rises, and remakes processed with after dried up of the washing fabric holder.Original cleaning solution can keep utilization in the cylinder bucket.Simultaneously, the utility model can adopt planetary impeller to replace traditional fixed shaft type impeller, increases work efficiency and clean rate.

Compare with the washing machine that present family comparatively generally uses, the utlity model has following advantage:

1, saves wash time, have higher detersive efficiency and clean rate.

The cleaning function of washing machine mainly is to lean on the rotating vane of agitator or pulsator around the rotation of fixed axis at present, or the rolling of cylinder is finished.Though this rotation can produce stronger current and mixing effect,, winding floating because of fabric is difficult to it is washed fully and stirs.The utility model has adopted planetary impeller, can form strong, mobile local eddy currents.Shape design in conjunction with bossings such as short bucket axle sleeve, the bucket end, sidewall, reinforcements, can make this washing machine possess simultaneously stirring, the multiple clean result such as wash, wash by rubbing with the hands, can carry out evenly, wash fully fabric with the less time, save wash time, and improved clean rate.

2, easy to use, save slurry and washing agent

During general home washings clothing,, often once be divided into several and wash because of clothes amount and color, lining and dirty situation.Existing single cylinder automatic washing machine is no matter can the cleaning solution in the cylinder barrel be used for the lower batch fabric of washing, all need to dewater after its discharging, thereby wasted big water gaging and washing agent, and to use make troubles (this is in lack of water and the water inconvenient area is more aobvious outstanding up and down).Though the cleaning solution of non-automatic washing machine can be fully used, need manually fabric to be pulled out again dehydration from cleaning solution, use very inconvenience.The utility model is to dewater after by short bucket fabric directly being held in the palm dried up, and original cleaning solution can also utilize in the cylinder bucket, thereby can save a large amount of water and washing agent.And, do not need artificial participation between washing of the present utility model and the dehydration, can realize full-automatic.

This specification has four accompanying drawings, Fig. 1 is the washing machine structure schematic diagram, structural representation during short barrel for impeller is installed in sidewall of Fig. 2, Fig. 3 is the star formula impeller structure schematic diagram when being not planet carrier with short bucket, Fig. 4 is the planetary impeller structure schematic diagram of bel-drivenn.

The utility model can adopt following structure, (shown in figure one): in the middle of the cylindrical washing tank bucket (14), hollow shaft (7) is housed, has four vertical slotted eyes (15) on this jack-post face, gear ring (10) is equipped with, lower end and fastening connection of power transmission shaft (20) in the upper end of axle.Leading screw (8) is housed in the hollow shaft, is with lifting nut (4) on the leading screw, the flange of nut is embedded in the hollow shaft slotted eye (15), makes lifting nut rotate also and can slide along slotted eye with hollow shaft.The leading screw upper end connects gear clutch collar (13) by slide key (11), and fixed gear ring (12) is housed on the support (9).

Motor (18) drives hollow shaft and rotates by belt pulley (19) (or gear), power transmission shaft (20), and torque is passed to other moving component in the cylinder bucket.When hollow shaft is rotated, if clutch collar (13) engages with fixed gear ring (12), leading screw will be fixed, and hollow shaft turn lifting nut rises or descends along leading screw.If clutch collar (13) engages with gear ring (10), leading screw will with the hollow shaft synchronous rotary, lifting nut does not also keep its present level constant because relatively rotating with leading screw.

The hollow shaft outside is with a short bucket axle sleeve (6), and its flange engages in slotted eye (15) with castellated with lifting nut, together lifting, and rotate with hollow shaft.On the short bucket two or more planet axis (2) can be installed, the upper end fixed installation impeller (3) of axle, lower end dress conical gear (1).Cylinder bucket bottom installs and fixes ring gear (21) (being sun gear), and its axis overlaps with hollow axle.When hollow shaft drives short bucket when the rotation of cylinder bottom of the barrel (namely being in the washing operating mode), gear (1) is with fixedly ring gear (21) is meshing, and drives impeller around fixed teeth ring axis rotation (revolution), rotates (rotation) around self axis simultaneously.If the current design needs, the planetary impeller of this washing machine also can be contained on the short bucket sidewall, and fixedly ring gear then can be contained on the corresponding position of cylinder bucket wall (such as figure two).

Short bucket sidewall and bottom have dewatering hole (17), leave enough draining spaces (16) between short bucket wall and cylinder bucket inwall, short bucket should be up big and down small, should be as far as possible near cylinder bucket internal diameter along maximum outside diameter on it, to guarantee that the fabric of being washed can all hold up, also can avoid clothing to be stuck between short bucket and the cylinder bucket inwall.Washing machine should adopt the washing cylinder cap of smooth interior surfaces.If short bucket diameter is bigger, can install positioning roller in cylinder bucket upper end, in case runout.

For making at a high speed (dehydration) and low speed (washing, the short bucket of lifting) rotation of hollow shaft, this washing machine uses two speed motors (also can adopt clutch speed-changing mechanism).The action of clutch collar (13) can be by solenoid control.

The utility model does not relate to washing machine shell, and vibration damping, supporting member advance, draining valve, and the improvement of part such as control circuit is omitted at this.

The short bucket of the mentioned lifting of the utility model can be used for the washing machine of other mode of washing, washing fabric is promoted or promotes holder water by it.When short bucket only plays castering action, when not needing rotary dehydration, all hold up and do not have jam (being particularly useful for the washing machine of non-cylindrical cylinder bucket) for guaranteeing fabric, should tap into cylinder bucket inwall along profile and size on it as far as possible.When planetary impeller was used for other washing machine, planetary mechanism can be by planet axis (23), and planet carrier (24) sun gear (25) and planetary gear (26) are formed (as figure three).Also can form (as figure four) by fast pulley (30) and belt pulley (29) and planet carrier (28) planet axis parts such as (27).

Each operating mode action of washing machine is as follows:

One, washing

Short bucket (5) places cylinder bucket (14) bottom, and short bucket top is to be washed fabric.Clutch collar (13) engages with gear ring (10).Leading screw (8), lifting nut (4) and short bucket (5) together rotate (positive and negative direction) with hollow shaft (7).Because of not relatively rotating between leading screw and the hollow shaft, lifting nut will be lacked bucket and will be limited in the rotation of cylinder bucket bottom.Conical gear (1) and fixedly ring gear (21) engagement, and under short bucket drives, rotate around hollow shaft, impeller (3) is done planetary motion, and fabric is washed.

Two, dehydration

Clutch collar (13) engages with fixed gear ring (12), leading screw maintains static, and hollow shaft is decided the direction rotation by giving, and drives lifting nut (4) and rises along the leading screw rotation, short bucket and impeller (comprising bevel gear (1)) together rise with lifting nut, with dried up of washing fabric holder.When short bucket rises, also do the rotation (this moment, impeller did not have rotation) around hollow shaft, so that fabric evenly distributes the dynamic balancing when guaranteeing dehydration in short bucket.Simultaneously, also be beneficial to the part cleaning solution and avoid fabric to be stuck between short bucket and the casing wall of draining.

After short bottom of the barrel broke away from the water surface fully, clutch collar (13) engaged with gear ring (10), and leading screw and hollow shaft are rotated synchronously, and lifting nut keeps present level constant with short bucket.Then, hollow shaft drives short bucket by equidirectional high speed rotation, will lack that institute's fabric of containing dewaters in the bucket.Cleaning solution in the cylinder bucket can keep according to circumstances (being used for the lower batch fabric of washing) or drain.

When fabric needed entry (namely short bucket need drop to the cylinder bottom of the barrel), clutch collar (13) engaged with fixed gear ring (12), and leading screw does not turn to, the hollow shaft reverse rotation, and lifting nut and short bucket drop to the cylinder bottom of the barrel.Clutch collar (13) engages with gear ring (10), can begin washing.
