Present embodiment can improve washing (-)off properties significantly by improving spray quinoline effect, the circulating effect of above-mentioned washing agent (interfacial agent) dissolution characteristics and cleaning solution.
In addition, owing to be provided with a plurality of cotton fiber filters, so can increase substantially the cotton fiber catch rate pro rata with the cotton fiber total flow that circulates.
In addition, by offering a plurality of circulation waterways, and with they spaced sets, and compared the balance in the time of to improve dehydration originally.
Below, with reference to accompanying drawing, describe with regard to the second embodiment of the present invention.
Fig. 4 A is the front view that watering is arranged at the present embodiment on circulation waterway top with nozzle; Fig. 4 B is its cutaway view; Fig. 4 C and 4D are the legend of existing watering with nozzle.Among the figure, 31 is the Water spray nozzle mouth of present embodiment, and it is made up of circulation waterway case 32 and fluid balancer box 33.34 is fluid balancer, and 35 is circulation waterway, and it is made up of circulation waterway case 32 and washing and dewatering groove 36.37,38 and 39 is the legend of existing watering with jet hole.
As above the watering of the automatic washing machine that is constituted illustrates by comparing with existing example with the function of nozzle.At first, existing example 4C has a plurality of apertures as the watering jet hole., mildly water on the washings as spilling from this cleaning solution that spills, can not produce problems such as water spatters from water sprager.But when the long cotton fiber that swims in the cleaning solution of circulation waterway entered jet hole 37, if this cotton fiber other end is flushed to jet hole 38 sides, then cotton fiber can expose from two of jet hole 37,38, and lodge is between two holes and can not fall any more.A lot of cotton fibers overlap, and finally can block the hole.Another existing example 4D has only a big jet hole, though above-mentioned cotton fiber blockage problem can not take place, gurgles the cleaning solution that flows out when being flushed on the washings from jet hole 39, can cause that cleaning solution splashes.
Present embodiment, by jet hole being made level to continuous groove shape peristome, cleaning solution becomes the film shape mildly to water to be spread across on the washings, so cleaning solution can not splash, in addition, do not have original example 4C to tangle the place of cotton fiber like that, do not stop up so can not produce cotton fiber yet.
As mentioned above, present embodiment both can avoid splashing of cleaning solution and cotton fiber to stop up, and cleaning solution can be watered widely again to be spread across on the washings.In addition, structurally, adopt circulation waterway case 32 and 33 two members of fluid balancer box, can easily constitute watering jet hole 31.
