Together with the depelopment of synthetic detergents, as well as with the changes in the life-style and life-senses and also with the betterment of income, the electric washing machine for home use has become very popularized, resulting in a great decrease in the labor of housechores. However, on the ogher hand the mechanization of washing has led to the use of large quantities of washing water and detergents, as compared to manual washing. In the present day washing, which depends largely on mechanized power, defects such as, unlevel washing, fabric damage and fabric intertwinement by washing requires much improvement. Also, in nowadays washing which lays stress on the appearance and feeling, give priority to the prevention of accidents during washing and neglect the original purpose of washing.This being the case, in the present study, an investigation was made on the trial manufacture of foam electric washing machine. In this washing machine, consideration is made particularly on t … More he economy of water resources, which in the future will be subjected to further restriction. Also, particular interest was laid on the prevention of water contamination and environmental pollution. Furthermore, due consideration was given to the prevention of damage and deterioration of clothing. In the foam washing machine, the clothing is not steeped directly in the detergent liquid, but instead,it utilizes small amounts of the foam of the detergent liquid and is an ultra low bath rate and warming type washing method.The foam washing machine consists of a fan which blows hot air into the detergent liquid, tank which serves as a receptacle of the detergent liquid, laundry sink, defoaming apparatus for the heating and shower type, and rinsing shower. First of all, turn on the switch for the fan, which sends hot air to the detergent liquid which is heated beforehand to approximately 50[70゜C and as a result, foam produced at a temperature of 50[70゜C dampens the clothing and also rinses. The soiled foam is broken in the defoaming apparatus and discharged. After 5[15 minutes, the valve at the bottom is released and rinsed by the shower. Repeated blowing of hot air within a degree so that the crease will not become fixed is done in order to perform hot air desiccation.Although the quantity of foam produced in the detergent liquid differ according to the type, concentration, co-existent material, and air weight flow of the surface active agent in the case of sodium oleate solution(0.25[0.5%) which possesses excellent foaming, stability,and detergency, the foam production is approximately 200[220 per litre under efficient air weight flow of 30[80 1/min.In the process of foam washing when a comparatively high concentration of a small amount of the detergent(bath rate 1:2[3, detergent 5[10g/2[3 1)is used, and when washed for 5[15 min. at an air weight flow of 30[80 1/min., washing temperature of 50[70゜C, a washing efficiency surpassing that of the presently used whirlpool type of washing machine may be obtained. It also reveals and anti-bacterial effect comparable to that of the boiling type of washing which is commonly done in the U.S. and Europe consequently, avery higienic standard is maintained.Furthermore, in the foam washing method the clothing is not directly steeped in the washing solution, but is blown upward in the stationary state, consequently, there is no washing defect, fabric intertwinement by washing, or uneven washing. Also, thin materials which are easily deformed by mechanical pressure can be washed together with other ordinary fabrics. Another benefit is the lack of unpleasant noise of the electric washing machine. Less

随着合成洗涤剂的发展，生活方式和生活观念的改变，以及收入的提高，家用电动洗衣机已经非常普及，从而大大减少了家务劳动。然而，另一方面，与手动洗涤相比，洗涤的机械化导致使用大量的洗涤水和洗涤剂。目前的洗涤主要依靠机械化动力，存在着洗涤不匀、织物损伤、织物缠绕等缺陷，需要进一步改进。在注重外观和感觉的现代洗涤中，往往把预防洗涤事故放在首位，而忽视了洗涤的本来目的，针对这种情况，本文对泡沫电动洗衣机的试制进行了研究。在该洗衣机中，特别考虑了洗衣机的性能。 ...更多信息 水资源的经济性，在未来将受到进一步的限制。此外，还特别关注防止水污染和环境污染。此外，还适当考虑到防止衣服损坏和变质。在泡沫洗衣机中，衣物不是直接浸泡在洗涤剂液体中，而是利用洗涤剂液体的少量泡沫，是一种超低浴速和加温型洗涤方法。泡沫洗衣机包括将热空气吹入洗涤剂液体的风扇、用作洗涤剂液体的容器的槽、洗衣槽，加热和淋浴类型的清洗设备，和冲洗淋浴。首先，打开风扇的开关，风扇将热空气输送到预先加热到约50[70 ° C的洗涤剂液体中，因此，在50[70 ° C的温度下产生的泡沫会润湿衣物并进行冲洗。污染的泡沫在清洗设备中破碎并排出。5[15分钟后，底部的阀门被释放并通过淋浴器冲洗。为了进行热空气干燥，在一定程度内反复吹送热空气，使得折痕不会固定。虽然在洗涤剂液体中产生的泡沫量根据表面活性剂的类型、浓度、共存物质和空气重量流量而不同，但在油酸钠溶液的情况下（0.25 ± 0.5%），其具有优异的发泡性、稳定性和去污性，在有效空气重量流量为30[80 l/l]下，泡沫产量约为每升200[220在泡沫洗涤过程中，当使用相对高浓度的少量洗涤剂（浴比1：2[3]，洗涤剂5[10 g/2[3 1]）时，并且当以30[80 l/min.]的空气重量流量洗涤5[15 min.]时，洗涤温度为50[70 ℃]时，可获得超过目前使用的涡流式洗衣机的洗涤效率。它还显示出与在美国和欧洲通常进行的沸腾式洗涤相当的抗菌效果，因此保持了非常高的标准。此外，在泡沫洗涤方法中，衣物不是直接浸泡在洗涤液中，而是在静止状态下向上吹，因此没有洗涤缺陷，洗涤时织物缠绕或不均匀洗涤。此外，薄的材料，很容易变形的机械压力，可以与其他普通织物一起洗涤。另一个好处是没有令人不快的噪音的电动洗衣机。少
