Water purifier control method and module, and water purifier system using same

A water purifier system comprising:

• a database configured to store water quantity information identified based on a data set including user information and container information;
• a camera module installed to capture a user and a container located under a water outlet;
• a water quantity control device configured to control a water quantity;
• and
• a processor connected to the database, the camera module, and the water quantity control device to control an operation of the water purifier system including the water quantity control device,
• wherein the processor is configured to:
• acquire captured image information from the camera module;
• acquire user identification information corresponding to the user and container identification information corresponding to the container from the image information;
• determine whether water quantity information corresponding to an input data set including the acquired user identification information and container identification information is stored in the database;
• control the water quantity control device based on the stored water quantity information, in response to determining that the water quantity information corresponding to the input data set is stored in the database;
• control the water quantity control device based on default water quantity information corresponding to the container identification information, in response to determining that the water quantity information corresponding to the input data set is not stored in the database;
• control the water outlet to dispense purified water into the container, based on the stored water quantity information or the default water quantity information;
• detect an amount of purified water in the container by using image information acquired through the camera module;
• control the water outlet to prevent the detected amount of purified water from overflowing the container:
• acquire actual dispensed water quantity information of the water quantity control device, and update the stored water quantity information in the database with the actual dispensed water quantity information or newly store the actual water quantity information as the water quantity information corresponding to the input data set;
• and
• control the water outlet to dispense purified water into the container, based on the updated water quantity information or the newly stored water quantity information.
