图中各附图标记的含义如下:The meaning of each reference mark in the figure is as follows:

1回气管            2泡沫功能前筒1 return trachea 2 foam function front cylinder

3回水管            4泡沫泵装置3 water return pipe 4 foam pump device

5漏斗状引水口      6负压形成桶5 Funnel-shaped water intake 6 Negative pressure forming barrel

7空气注入管        8圆柱形接触头7 Air injection pipe 8 Cylindrical contact head

具体实施方式 Detailed ways

如图1、图2所示的洗衣机用泡沫发生器,包括有回气管1,其与众不同之处在于:在回气管1的一端连入泡沫功能前筒2的回气接口,在气泡功能前筒上同时连接回水管3的输入端。并且,在回水管3的输出端上连接有泡沫泵装置4。The foam generator for washing machine as shown in Figure 1 and Figure 2 includes a return air pipe 1, which is different in that: one end of the air return pipe 1 is connected to the air return interface of the front cylinder 2 with foam function, and the air return interface of the bubble function The front cylinder is connected to the input end of the return pipe 3 at the same time. Moreover, a foam pump device 4 is connected to the output end of the water return pipe 3 .

就本发明一较佳的实施方式来看,泡沫泵装置4包括有漏斗状引水口5,在漏斗状引水口5的出水端设置有负压形成桶6。并且,负压形成桶6的横截面大于漏斗状引水口5出水端的横截面。同时,在负压形成桶6的一侧设有空气注入管7。As far as a preferred embodiment of the present invention is concerned, the foam pump device 4 includes a funnel-shaped water intake 5 , and a negative pressure forming bucket 6 is provided at the water outlet end of the funnel-shaped water intake 5 . And, the cross-section of negative pressure forming bucket 6 is larger than the cross-section of the water outlet end of funnel-shaped water intake 5 . Meanwhile, an air injection pipe 7 is provided on one side of the negative pressure forming barrel 6 .

进一步来看,为了有条提升负压形成的效果,有利于漏斗状引水口5与负压形成桶6的有效对接,本发明在漏斗状引水口5的出水端与负压形成桶6的接触端处设有圆柱形接触头8。Looking further, in order to improve the effect of negative pressure formation in an orderly manner, which is beneficial to the effective docking of the funnel-shaped water intake 5 and the negative pressure formation bucket 6, the present invention contacts the water outlet end of the funnel-shaped water intake 5 with the negative pressure formation bucket 6 A cylindrical contact head 8 is provided at the end.

本洗衣机用泡沫发生器的工作过程如下:带有洗衣粉的水流通过回水管3注入与气泡功能前筒相连的泡沫泵装置4中。接着,伴随着水的进一步流入,根据伯努利方程“动压+静压+位压”为定值,泡沫泵装置4中动压的变化会引起静压的变化,即可通过泡沫泵装置4管壁的变化引起水流速的变化即动能的变化。The working process of the foam generator for the washing machine is as follows: the water flow with washing powder is injected into the foam pump device 4 connected to the front cylinder of the bubble function through the return pipe 3 . Then, along with the further inflow of water, according to the Bernoulli equation "dynamic pressure + static pressure + potential pressure" as a fixed value, the change of dynamic pressure in the foam pump device 4 will cause the change of static pressure, which can pass through the foam pump device 4 The change of the pipe wall causes the change of the water velocity, that is, the change of the kinetic energy.

具体来说,水流由漏斗状引水口5流入负压形成桶6时,由于负压形成桶6的横截面大于漏斗状引水口5出水端的横截面。由于动压变大、静压变小,圆柱形接触头8所述位置的处压力小于外界大气压,所以该处形成负压。伴随着洗衣机中电机持续工作,负压形成桶6通过空气注入管7会有空气不断进入,水的振动激发泡沫的持续形成。接着,通过泡沫形成和裂解时产生的能量,能达到深层洗涤的效果。换句话说,通过水流速的变化产生持续负压,做到空气、水、洗衣粉的融合以及泡沫的产生。Specifically, when the water flows from the funnel-shaped water intake 5 into the negative pressure-forming barrel 6, the cross-section of the negative-pressure-formed bucket 6 is greater than the cross-section of the funnel-shaped water intake 5 outlet end. As the dynamic pressure increases and the static pressure decreases, the pressure at the position of the cylindrical contact head 8 is lower than the external atmospheric pressure, so a negative pressure is formed there. Along with the continuous operation of the motor in the washing machine, the negative pressure forming tub 6 will have air continuously entering through the air injection pipe 7, and the vibration of the water will stimulate the continuous formation of foam. Next, a deep cleansing effect is achieved through the energy generated during foam formation and breakdown. In other words, through the change of water flow rate, continuous negative pressure is generated to achieve the fusion of air, water and washing powder and the generation of foam.

通过上述的文字表述并结合附图可以看出,采用本发明后,通过泡沫发生器的存在有效利用负压提升了泡沫的产出率,缩短了洗涤时间8%以上。并且,能够减少洗衣粉的使用量50%以上。同时,由于提高了泡沫的产出率,能够减少耗水量,提高洗衣粉溶解度,降低洗衣粉残留。再者,通过产出丰富的泡沫提高用户对洗净衣物的确认感和信任感,提高洗净比在10%以上,同时缩短洗涤时间。再者,本专利的气泡发生器,通过水流速变化的控制形成持续负压,将空气注入水中,让空气和水、洗涤剂相互结合产生丰富的泡泡,深入纤维深处,从而有效去除衣服中的污渍,由于强大的气泡发生器在低温下也能快速分解出丰富的泡沫,因此有效起到了省电的作用。此外,丰富泡沫能所形成的“泡沫垫”还能有效避免衣物与内筒的直接接触,降低衣物磨损。It can be seen from the above text description and the accompanying drawings that after adopting the present invention, the existence of the foam generator effectively utilizes the negative pressure to improve the output rate of foam and shorten the washing time by more than 8%. And, can reduce the usage amount of washing powder by more than 50%. At the same time, due to the increased foam output rate, water consumption can be reduced, the solubility of washing powder can be improved, and the residue of washing powder can be reduced. Furthermore, by producing rich foam, the user's sense of confirmation and trust in washing clothes can be improved, the washing ratio can be increased to more than 10%, and the washing time can be shortened at the same time. Furthermore, the air bubble generator of this patent forms a continuous negative pressure through the control of the change of water flow rate, injects air into the water, and makes the air, water, and detergent combine to generate rich bubbles, which penetrate deep into the fiber, thereby effectively removing clothes The stains in the water, because the powerful bubble generator can quickly decompose rich foam at low temperature, so it effectively saves electricity. In addition, the "foam pad" formed by the rich foam energy can effectively avoid the direct contact between the clothes and the inner tube, and reduce the wear and tear of clothes.
