Description

The steel ladle of water saving automatic washing machine

The utility model belongs to a kind of annex of washing machine, specifically a kind of steel ladle that is used on the water-saving type automatic washing machine.

General double-cylinder type impeller automatic washing machine is when work, and dehydration barrel communicates with steel ladle.That is to say between dehydration barrel and steel ladle and have identical water level.In actual use, the water that is positioned between dehydration barrel and steel ladle is otiose, and many water-saving type laundry machines reach the water saving purpose by saving this part water.Want to save this part water, will solve the sealing problem of dehydration barrel self on the one hand, also will solve the sealing problem in washing, dehydration between dehydration barrel and steel ladle simultaneously.

The purpose of this utility model is to propose a kind of steel ladle of water saving automatic washing machine of uniqueness, with simplified structure, improve sealing property, reduce the waste of water.

Its main technical schemes comprises the staving and the bucket end, it is characterized in that seal cover and obturating cup are arranged at the bottom of the bucket, between the inwall of the outer wall of obturating cup and seal cover, sealing ring is set, the sealing circle is by being positioned at inboard tubular inner edge, being positioned at the tubular outer rim in the outside and being positioned at the top annular upper limb that inside and outside edge is fused and constitute, the upper end of inner edge have upwards slope inwardly extend on lips and teeth, the following lips and teeth that slope inwardly downwards and extend are arranged in the lower end of inner edge;

In the upper limb of sealing ring and outer rim, L shaped skeleton is arranged down; Between the outer rim of seal cover and steel ladle, sealing strip is set;

Seal cover and obturating cup all are placed on the main shaft of washing machine, at the middle part of obturating cup through hole are set, and static pipe is set below at the bottom of bucket, and the passage that the through hole utilization is arranged at below the seal cover is communicated with static the pipe; Clutch is installed below at the bottom of bucket; Dehydration barrel is arranged in steel ladle, the dehydration orifice plate is set, balance ring is set on the top of dehydration barrel at the inwall of dehydration barrel.

For realizing the function of water saving, guarantee the operate as normal of automatic washing machine again, the dynamic seal (packing) structure of this function admirable that this paper proposed is made of obturating cup and sealing ring, obturating cup and dehydration barrel and clutch adopt screw to be fastenedly connected, guarantee the perpendicularity between dehydration barrel and the clutch, to improving the stationarity of washing machine running, reducing the washing noise has positive effect; Owing between obturating cup and seal cover, be provided with sealing ring with special shape, when both cooperate, it is very unique to have, rational contact shape, utilize the lips and teeth on the sealing circle and the interference fit of obturating cup, can play good sealing effectiveness, simultaneously, after in sealing ring, being provided with L shaped skeleton, improved the intensity of sealing ring, during installation, can make the certain pretightning force of generation between sealing ring and seal cover and obturating cup, make the sealing effectiveness of lips and teeth better, sealing ring adopts the good elastomeric material of anti-wear performance to make, and is coated with during installation with lubricating grease, when reducing high speed dewatering with the friction of obturating cup, the realization dynamic seal (packing).

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is the bucket end and clutch configuration figure.

Fig. 3 is the connection status figure of sealing ring and obturating cup and seal cover.

As shown in the figure:

Seal cover 4 and obturating cup 12 are being arranged) at the bottom of the bucket in 7, between the inwall of the outer wall of obturating cup 12 and seal cover 4, sealing ring 13 is set, sealing circle 13 is by being positioned at inboard tubular inner edge 15, be positioned at the tubular outer rim 19 in the outside and be positioned at top inciting somebody to action, outer rim 15, the 19 annular upper limbs that fuse 17 constitute, the upper end of inner edge 15 have upwards slope inwardly extend on lips and teeth 16), the following lips and teeth 20 that slope inwardly downwards and extend are arranged in the lower end of inner edge 15, in the upper limb 17 of sealing ring 13 and outer rim 19, L shaped skeleton 18 is arranged down, to improve its intensity, between the outer rim of seal cover 4 and steel ladle, sealing strip 14 is set, to avoid the water in the passage 5 to leak at this

Seal cover 4 all is placed on the main shaft 9 of washing machine with obturating cup 12, at the middle part of obturating cup 12 through hole 11 is set, and static pipe 7 is set below 6 at the bottom of bucket, and the passages 5 that through hole 11 utilizations are arranged at below the seal cover 4 are communicated with static pipe 7; Clutch 8 is installed, so that operation and control have dehydration barrel 2 in steel ladle below 6 at the bottom of bucket, inwall in dehydration barrel 2 is provided with dehydration orifice plate 1, so that dehydration is provided with balance ring (10) on the top of dehydration barrel 2, the stationarity when turning round to improve washing machine.

During laundry, water flows into the static state pipe that is attached thereto and discharges from the seal channel of through hole under seal cover of obturating cup, after water level surpasses the sealing ring position, because the pressure effect, the lips and teeth of sealing ring are against the outer wall of obturating cup, can guarantee that water does not enter in the steel ladle; During dehydration, draining valve is opened, water is at first discharged by the through hole on the obturating cup, static pipe to the draining valve (not shown) of passage under the seal cover, when dehydration barrel runs up, obturating cup and sealing ring are in dynamic connection state, the action of centrifugal force that clothes institute water content produces owing to rotation at a high speed enters in the steel ladle from the top of dehydration barrel, discharges (not shown) by intervalve to draining valve.
