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.

洗衣機是家中最重要的電器設備之一。然而，由於洗衣機耗費大量電力和水量，對環境構成極大威脅。因此，我們設計了(H2O)^-1 machine（慳住洗）。
慳住洗洗衣機會先將衣服推進漏斗狀的間隔，中間的間隔門會根據衣物量打開及關上，讓衣服掉進滾筒。滾筒中則會有裝有酵素的轉盤將酵素塗在衣服上。底部亦配備電磁鐵拋動衣物，確保衣物能夠接觸酵素，電磁鐵上的壓電發電機亦會將拋動衣物時所產生的壓電轉換為電能。衣服在慳住洗洗衣機底部的水槽中沖洗完成後，慳住洗的使命就完成了！
