Patent attributes
A washing machine has a washing water supplier which includes a storage tank storing washing water and a cooler decreasing a temperature of the washing water supplied from the storage tank and a washing tub. The washing water storage apparatus keeps the temperature of the washing water low by circulating the washing water of the storage tank through the cooler. The washing tub is connected to the washing water supplier to receive the washing water supplied from the storage tank and use the washing water to wash laundry. A washing machine can use ozone micro-bubbles. Ozone micro-bubbles are generated for easy disinfection and sterilization, without using any high-pressure rotation pump. After the ozone is generated in an ozone generation apparatus, the ozone forms a water-ozone mixture in an ozone mixing unit. The mixture is atomized into micro-bubbles in the rotation pump and returns to the washing tub.
