Abstract
Provided is a liquid dispensing device. The liquid dispensing device includes an internal member coupled to a sink and a nozzle. A sterilized liquid module is provided in the internal member and includes a casing having an inner space to receive the liquid, and at least one electrode positioned parallel to a longitudinal direction of the casing, installed in the inner space of the casing, and configured to generate the sterilized liquid through electrolysis of liquid in the inner space of the casing.
Claims20
A liquid dispensing device comprising:
- a casing having an inner space to receive a liquid, the casing having an inlet and an outlet;
- a inflow tube coupled to the inlet to introduce the liquid into the inner space of the casing;
- at least one electrode provided in the inner space and configured to produce sterilized liquid through electrolysis of the liquid introduced into the inner space;
- a controller to control to activate or deactivate the at least one electrode such that sterilized liquid is produce when the at least one electrode is activated;
- a discharge tube coupled to the outlet and configured to discharge the sterilized liquid when the at least one electrode is activated or to discharge liquid passing through the inner space from the inflow tube when the at least one electrode is deactivate;
- and a first valve having a valve inlet and a first valve outlet and configured to pass the liquid from the discharge tube between the valve inlet and the first valve outlet when the at least one electrode is deactivated or to pass the sterilized liquid from the discharge tube between the valve inlet and the first valve outlet when the at least one electrode is activated;
- wherein when the controller receives a command for the sterilized liquid, the controller activates the at least one electrode for a first prescribed period of time such that a first prescribed quantity of sterilized liquid flows between the valve inlet and the first valve outlet, and deactivates the at least one electrode to allow the liquid to flow through the inner space of the casing and the liquid to flow between the valve inlet and the first valve outlet for a second prescribed period of time.
