洗衣机是家中最重要的电器设备之一。然而，由于洗衣机耗费大量电力和水量，对环境构成极大威胁。因此，我们设计了(H2O)^-1 machine（悭住洗）。
悭住洗洗衣机会先将衣服推进漏斗状的间隔，中间的间隔门会根据衣物量打开及关上，让衣服掉进滚筒。滚筒中则会有装有酵素的转盘将酵素涂在衣服上。底部亦配备电磁铁抛动衣物，确保衣物能够接触酵素，电磁铁上的压电发电机亦会将抛动衣物时所产生的压电转换为电能。衣服在悭住洗洗衣机底部的水槽中冲洗完成后，悭住洗的使命就完成了！

Washing machine is one of the most essential electrical appliances in modern homes. However, they pose a threat to the environment due to their high energy consumption and excessive water use. Therefore, we are proposing our new (H2O)^-1 machine to tackle this problem.
The (H2O)^-1 machine consists of two main parts: the enzyme application process and rinsing. Clothes descend from a funnel-like structure, and a door mechanism opens and closes based on the amount of laundry, allowing a gradual release of garments into the tumbling channel. In the tumbling chamber, a turntable with enzyme-filled tubes applies the enzyme liquid onto the clothes. Electromagnets toss the clothes to ensure thorough interaction between the fabric and enzymes, effectively removing dust and dirt. Piezoelectric generators at the bottom of the tumbling chamber convert mechanical energy from the clothes' movement into electrical energy. After tumbling, the clothes are rinsed in a tank filled with clean water, and excess water is squeezed out through compression. The water is drained through a slanted base, and sensors facilitate automatic operation. Once the process is complete, the system refills the tank with water for the next cycle.
The (H2O)^-1 machine reduces electricity consumption and minimizes water usage. By using enzymes instead of detergents, the machine eliminates the need to heat water, which accounts for a significant portion of energy usage in traditional washing machines. The machine only requires water for the final rinsing stage, where clothes are compressed and enzymes are effectively released and diluted. This ensures thorough rinsing while minimizing water consumption.
