Disinfection apparatus of Legionella in hot water storage tank and method thereof

摘要

The present invention relates to a sterilization apparatus for legionella in a hot water storage tank and a method thereof. Specifically, the sterilization apparatus for legionella in a hot water storage tank of a notified heat source generator comprises: a sterilization function operation button to determine whether a consumer will operate a sterilization function of legionella on a temperature control device; a sterilization function operation display unit to display a state of the sterilization function of legionella when operating the sterilization function of legionella; and an alarm or a buzzer to notify the consumer to pay attention to a high temperature when an internal temperature (Ttank) of a hot water storage tank is higher than a hot water setting temperature (Tset1) of the hot water storage tank. Or a sterilization function operation button to determine whether consumer will operate a sterilization function of legionella on the temperature control device, and a sterilization function operation display unit to display a state of the sterilization function of legionella when operating the sterilization function of legionella are installed. And a bypass pipe with a bypass valve is installed between a water supply inlet and a hot water outlet of the hot water storage tank, and a bypass valve driving unit is installed on an output side of the control unit. Therefore, legionella living in the hot water storage tank can be sterilized at any time by an operation of the sterilization function operation button. Sterilization function conditions of legionella in the hot water storage tank can be set to improve convenience of hot water use of the consumer by reasonable energy use and maintaining used hot water temperature. Also, the risk of burns of consumers by discharging high temperature water can be prevented when operating the sterilization function of the hot water storage tank or using hot water after operating the sterilization function.
