Abstract
The water provisioning system mainly contains a selection switch, a water volume switch, a human-machine interface (HMI), a RO waste water recycling device, an electromagnetic valve, a RO water purification device, an antichlor device, an aeration pipe assembly, a first ozone module, and a second ozone module. The selection switch selects a type of water to use. The RO water purification device filters water from a low-temperature water source, stores purified water in a storage barrel, and provides high-quality drinking water. The 70% water from the RO water purification process that fails the drinking water standard is recycled through the RO waste water recycling device. The low-temperature water source is connected to an antichlor device and the water is therefore dechlorinated. The first and second ozone modules are used to produce ozonated water and to release ozone through the aeration pipe assembly into the kitchen cabinet for deodorization and sterilization.
