Abstract

The utility model discloses a gearing type multiple impeller cylinder washer. The dewatering cylinder of the utility model is provided with 2-3 impellers which are driven in the variable speed way by a motor through a transmission gear box, and the impellers are simultaneously rotated in the same direction, and the wash is carried out; the impellers are simultaneously reversely rotated, and the dewatering function can be carried. A plurality of kinds of water currents formed by the rotation of a plurality of the impellers synthesize a combined cycle water current, washings can not be mutually twisted with easily, washing effect is improved, and the wear degree of the washings are decreased; meanwhile, the impellers do not need to make the intermittent forward and reverse rotation, a program controller is simplified, and the service life of the motor is extended.

Description

Many impellers of gear type overlapping drums washing machine

The utility model belongs to the washing machine class, particularly a kind of overlapping drums washing machine.

The current overlapping drums washing machine that generally uses all belongs to single impeller overlapping drums washing machine, and its washing and dehydration are controlled by clutch.The outer shaft of clutch connects the dehydration cylinder, and interior axle upper end is fixed with impeller, and belt pulley is being fixed in the lower end, and belt pulley is connected with motor by belt.During washing, axle makes impeller do intermittent positive and negative rotation in the driven by motor clutch, and the dehydration cylinder does not change.During dehydration, make tractive magnet inhale the water valve that begins to rehearse by switch, effluent sewerage is embraced spring then and is held outer shaft tightly, so interior outer shaft while one-directional rotation causes dehydration cylinder and impeller to rotate simultaneously, dries washings.This washing machine has alleviated the intensity of housework greatly, brings great convenience to people.But this washing machine remains in following shortcoming: 1. owing to have only an impeller in the cylinder, formed current are single, clothing is twined easily mutually, so decontamination is inhomogeneous, and particularly the spun fabric abrasion are big to washings.2. impeller need be done intermittent forward and reverse rotation, changing the direction of a stream of water, commutation can be subjected to very big resistance in a flash, make motor unbalance stress when work, repeatedly starting the frequent rotation direction that changes in the short time repeatedly will directly influence electronic service life.3. the clutch configuration complexity when clutch breaks down, will cause the complete machine paralysis or interrupt washing procedure.4. washing procedure is too much, makes programme-control part complexity.

The purpose of this utility model is developed a kind of clutch that do not need exactly, and washing procedure is simplified, the novel overlapping drums washing machine that clean result is good.

The purpose of this utility model realizes by following technical proposals: the dehydration cylinder bottom portion in the washing tank is provided with a plurality of impellers, by the speed-changing gear box variable speed drives, makes the simultaneously same direction rotation of many impellers by motor, washs; Under the cyclelog operation, the motor counter-rotating, many impellers reverse simultaneously, dewater.The concrete structure of the technical program is as follows: driving gear is equipped with in the interior axle upper end of spindle assembly, and driving gear is meshed with 2-3 travelling gear simultaneously, and impeller all is equipped with on the top of every rack wheel axle.Ratchet is equipped with at interior axle middle part, and belt pulley is equipped with in the lower end, and belt pulley is connected with motor by belt.Ratchet is fixed on the dehydration cylinder bottom face, and outer shaft then is fastened on dehydration cylinder bottom portion.Operation principle of the present utility model is such: motor power is connected and is rotated, axle driving gear in driving, and driving gear rotates to same direction by the impeller that 2-3 travelling gear drives its top respectively.At this moment formed multi-strand flow in the washing tank, a plurality of little eddy current that promptly a plurality of impellers top forms, a plurality of little eddy current phase tangent plane in twos form the convective region of flowing water one by one, and along the maelstrom of casing wall rotation.Washings is beaten repeatedly, is pushed and crumpled in the synthetic combined-circulation current of these multiple current and reached the washing purpose.Because what form in the washing tank is one combined-circulation current, do not change the direction of a stream of water so do not need impeller to do intermittent positive and negative rotation, a plurality of impellers rotate towards a direction all the time in whole washing process.Washing finish carry out draining after, motor is the axle counter-rotating in switching counter-rotating, making, ratchet chucking ratchet joins outer shaft and interior axle together, axle rotated in outer shaft was promptly followed, the dehydration cylinder that links with outer shaft rotates thereupon, washings is dried the washing end.The control circuit control that the exercises of the utility model washing machine are made up of cyclelog (electric motor type timing or computer), water level control relay (pressure sensor) etc.

The advantage of many impellers of the utility model overlapping drums washing machine is that it is simple in structure, and is easy to manufacture, and program simplification is easy to maintenance.The gearbox of being made up of driving gearshaft, travelling gear, spindle assembly etc. has replaced baroque clutch.Impeller need not done intermittent forward and reverse rotation in washing process, has both reduced washing procedure, has simplified cyclelog, has prolonged the service life of motor again greatly.The eddy current of the mutual bump that many impellers form can reduce the mutual winding of washings, excite the vigor of washing agent effectively, the suffered various power in each position of washings are more uniform in the combined-circulation current synthetic by multiple current, have therefore improved clean result greatly.Mutually the buoyancy that produces of the current of bump has reduced impeller and the casing wall abrasion degree to washings.Therefore the utility model also have power saving, save time, laborsaving, economize advantage such as washing agent.

Below in conjunction with accompanying drawing the technical solution of the utility model is described further.

Fig. 1 is the utility model (double wave wheel type) longitudinal sectional view;

Fig. 2 is the utility model (double wave wheel type) gearbox designs cutaway view;

Fig. 3 is the utility model (three impeller types) vertical view.

With reference to accompanying drawing, driving gear (2) is equipped with in the interior axle (1) of spindle drive assembly upper end, Driving gear (2) is meshed with 2-3 travelling gear (3) simultaneously. Every rack wheel Impeller (5) all is equipped with on the top of axle (4). Ratchet (6), lower end are equipped with in interior axle (1) middle part Belt pulley (7) is housed, and belt pulley (7) is connected with motor (9) by belt (8). Ratchet (10) be fixed on dehydration cylinder (11) bottom surface, outer shaft (12) then is fastened on dehydration cylinder (11) The bottom.

An exemplary embodiments of the present utility model: shell, washing tank and dehydration cylinder are identical with the current single impeller overlapping drums washing machine that generally uses, driving gear (2), travelling gear (3), ratchet (6) and the available nylon of ratchet (10) or alloy material are annotated pressure surface and are become, and travelling gear (3) is (2-5) with the gear ratio of driving gear (2): 1.The diameter of impeller (5) can be identical, annotates with plastics to be pressed into, and the distance between the impeller (5) is the 10-50 millimeter.The intermittent forward and reverse rotation sequence circuit of impeller in the control section cancellation washing process.
