Description

A kind of outer bung with spray function
Technical field
The utility model relates to the washing machine field, specifically is a kind of outer bung, especially a kind of outer bung with spray function.
Background technology
At present, the whole world emerges in an endless stream about the development types of washing machine, answer the needs of market people life, the designer has developed the washing machine with various functions from different angles, as: the washing machine of centrifugal force laundry, have spray equipment washing machine, have double dynamical washing machine etc.
PANASONIC adopts centrifugation, drive the rotation in the same way of water by the rotation of interior bucket, the water of rotation is the spray equipment on the bung outside the skewed slot on outer barrel wall is injected into because of inertia and centrifugal force, impact the interior cleaning solution of bucket in the bucket in the formation waterfall shape is sprayed at behind the spray equipment on the outer bung of water process and form more foam, be i.e. so-called " foam is washed " technology.
Application number is to disclose a kind of washing machine in 98107000.0 the patent documentation, the driving mechanism that possesses the Washing dewatering tub that holds washings, makes steel ladle that this Washing dewatering tub can be received and rotation drive this Washing dewatering tub with rotating freely, it is characterized in that rotation with described Washing dewatering tub make washings rising between the Washing dewatering tub outside and steel ladle, from sprinkle water in the direction Washing dewatering tub.
From documents disclosed content as can be seen, the purpose of this documents is to provide a kind of rotation that does not rely on pulsator, makes the washings circulation, does not make the washings damaged, improves the scourability washing machine inhomogeneous with reducing washing.The mixing power that produces because of the rotation of Washing dewatering tub constantly rises the descend outside of Washing dewatering tub and the water surface between steel ladle of the central portion of the washings water surface in the steel ladle, until make washing water surface water level surpass Washing dewatering tub the upper end height and to the inside watering of Washing dewatering tub.Also can be further be set to above the steel ladle at the lid that forms the watering discharge portion between itself and Washing dewatering tub top, in Washing dewatering tub circumferential lateral surface and steel ladle, forming the guide wall that the washings that are suitable for corresponding Washing dewatering tub rotation and rise lead above at least one of all sides.Documents is compared with prior art at that time, has really not damage washings and improve scourability, simultaneously can reduce beneficial effects such as washing is inhomogeneous.But, this simple water level in the washtub being risen by centrifugal action causes spray to wash the laundering process of benefit, in fact there are some defectives, it has certain requirement to the rotating speed of washtub and the water level of interior bucket, when rotating speed, the water level of interior bucket do not reach when necessarily requiring, the water of interior bucket can't reach the mouth spray place of the outer bung of washing at all, also just can't form the effect that spray is washed.
Application number is the washing methods that discloses a kind of washing machine and used it in 02155940.6 the utility application prospectus, effectively remove in the washing machine of dirt in the effect that utilizes detergent foam, behind detergent dissolution, on making detergent water generate detergent foam and being injected into washings in the washing and dewatering groove from the top, guarantee good cleaning strength and reduce the inhomogeneous generation of washing.
Application number is to disclose a kind of washing machine that makes the washings circulation wash and clean in the utility model patent of 02142716.X, this washing machine turns round the washing and dewatering groove of accommodating washings that contains freely in aqua storage tank, and turn round driving by motor, inner face at aqua storage tank is formed with pump chamber, revolution by the washing and dewatering groove concentrates on pump chamber with the washings between washing and dewatering groove and the aqua storage tank, and the circulating path through being connected with pump chamber pumps up water upward.In fact, this also is a kind of washing machine that washings are recycled, and by pump chamber washings is circulated by circulation waterway.
In above-mentioned documents, the concept of Centrifugal washing machine and spray washing machine is disclosed, compare with previous washing machine and to have large improvement at aspects such as principle, function, structures, still, still have following shortcoming at these washing machines of the prior art:
When 1) adopting centrifugation to form the waterfall spray, the rotating speed of water level and interior bucket is had certain requirement, and if water level cross low or interior bucket rotating speed when not enough, all do not reach the effect of waterfall spray;
2) in the existing washing machine, what have does not arrange special spray equipment at all, and it is long-pending excessive that the spray equipment that has takies the capping of outer bucket, has influenced the flood effectiveness of washing machine;
3) water jet water outlet place of existing washing machine does not arrange special shelves water plate, and it is indefinite that waterfall is injected in barrel interior front and back position, during current before the time after instability;
4) spray equipment is independent structures, needs extra installation and production cost.
Application number be 200410004726.9 utility model patent disclose a kind of in the cyclic spraying washing machine, adopt the washing methods of circulated sprinkling, cover at outer barrel of washing machine a spray equipment be set, reach the effect that spray is washed.This spray equipment comprises: water injection pipe, water cavity, waterfall formation place, postive stop baffle, and water cavity is made up of upper water cavity and following water cavity.Washings are pressed into spray equipment by water pump through circulation pipe, at first enter water cavity, and water is temporary at this position.Washings just arrive waterfall formation place then, and washings are namely formed the blank of waterfall herein by " compressing ".Last waterfall is spacing by postive stop baffle, is sprayed in the interior bucket.
Though this kind spray equipment can reach the effect that spray is washed, and still has following shortcoming:
1) washing process, shower water can dabble, especially middle and high water level circulated sprinkling washing, it is bigger to dabble, and has potential safety hazard;
2) bucket center in depart from spray drop point zone, the spray utilization rate is low;
3) spray water flow is inhomogeneous, and spray washing, wash effect are bad;
4) spray equipment complex structure.
In view of this spy proposes the utility model.
