Abstract

PROBLEM TO BE SOLVED: To provide a washing machine capable of cleaning and draining a large quantity of washing drainage in a short time while preventing clogging of a filter. SOLUTION: Washing drainage drained from a washing tub 1 after finishing the wash of clothes is led into a coagulating tub 3 via a drain pipe 8. At this time, a coagulant solution is simultaneously injected from a coagulant solution container 4. Cleaning components such as a surfactant in the washing drainage react on a coagulant to form aggregates of relatively large grains. Furthermore, the washing drainage is agitated while blowing in air by an aerating type agitator 5, so that the aggregates float entraining air, and the washing drainage is separated in an upper aggregate layer 20 with the relatively large ratio of aggregates, and a lower water layer 21 without the large ratio of aggregates. Time required for drainage can thereby be shortened by a large margin by draining from the lower water layer 21 at a stroke. Since aggregates in the drainage are eliminated by filter 10 to drain clear water, a washing machine excellent from the viewpoint of environment can be provided. The recovered aggregates can be easily taken out.

2. Description of the Related Art Conventionally, washing of laundry such as clothes in a washing machine mainly contains an anionic synthetic surfactant such as sodium linear alkylbenzene sulfonate (LAS) or a higher alcohol sulfate. Synthetic detergents are used. Although a synthetic surfactant has an excellent cleaning effect, it has a greater environmental impact than soap. That is, since the synthetic surfactant in the wastewater is relatively difficult to biodegrade, it itself pollutes the water quality and damages the microorganisms, causing a great damage to the water environment.

Japanese Patent Publication No. 182896 proposes an electric washing machine having a function of adding a divalent metal chloride to washing waste water to precipitate a detergent component and remove it with a filter. Japanese Patent Application Laid-Open No. 10-118390 discloses a washing machine that purifies washing wastewater by coagulating contaminants using an electrolysis reaction.

However, of these conventional methods, the method of precipitating and filtering the detergent component merely involves injecting the metal chloride solution into the flowing washing wastewater, which results. The precipitate cannot be aggregated sufficiently and remains mostly in the form of fine particles. For this reason, when filtering this, clogging of the filter is likely to occur, which may increase water passage resistance and significantly reduce the amount of treated water. Therefore, there is a problem that the filter needs to be replaced or washed frequently, and the maintenance is troublesome and costly. On the other hand, in the method by electrolysis, if the washing sewage flows and then electrolyzes to generate metal ions, it takes time to sufficiently react with contaminants such as surfactants or the area of the electrode. And the number needs to be increased.

As described above, according to the present invention, the washing water drained from the washing tub after the clothes have been washed is guided to the washing water treatment tank, and the coagulant is added and stirred at the same time. The particle size of the aggregate formed by the reaction of the detergent component in the wash water with the flocculant becomes relatively large. Therefore, even if the washing water is drained while being filtered by the filter, clogging of the filter hardly occurs, and maintenance such as replacement of the filter is facilitated. Moreover, by agitating the washing water in the washing water treatment tank with or without air, the washing water is separated into a portion containing a relatively large amount of aggregates and a portion not containing the aggregates. If you drain first, you can significantly reduce the time it takes to drain,
A large amount of washing water can be purified and drained at one time.
