The invention relates a purifying system and a sterilization method. The purifying system comprises the following components: a filter part, which comprises a filter for supplying raw water filteringsupplied from external part; a storage tank, which comprises a flowing inlet and a flowing outlet, wherein the flowing inlet is used for purified water filtered by the filter to flow in, the flowing outlet is used for purified water to flow out, and the storage tank is used for storing purified water; a cover covering an upper portion of the storage tank and forming a top surface of the storage tank; an ultraviolet light emitting diode which is provided on the upper side of the inside of the storage tank, is spaced apart from the surface of the purified water stored in the storage tank, directly faces the surface of the purified water, and sterilizes the stored purified water by irradiating ultraviolet light onto the surface of the purified water in a non-contact state with the purified water, the ultraviolet light-emitting diode including: a light-emitting unit capable of sterilizing purified water by irradiating the stored purified water with light, the light-emitting unit being provided to a holder cover inside the storage tank; a printed circuit board electrically connected to the light-emitting unit and coupled to the holder cover; and an electric wire unit electrically connected to the printed circuit board and capable of supplying power supplied from the power supply unit to the light-emitting unit.
Description
[0001] This application is a divisional application of an application with an application date of October 23, 2015, an application number of 201510695309.1, and an invention title of "Water Purification System and Sterilization Method". technical field [0002] The present invention relates to a water purification system provided with a sterilizer for sterilizing purified water circulating inside a water storage tank, and a purified water supply device provided with the same. Background technique [0003] A water storage tank is installed in a dispenser of a water purifier or a refrigerator. Since the water storage tank supplies water after storing it for a predetermined period of time, bacteria such as microorganisms, germs, and viruses can multiply in the water stored in the water storage tank. Therefore, the water stored inside the water storage tank is sterilized in various ways using a mercury lamp, a halogen lamp, or an ultraviolet light emitting diode (UV LED). [00...
