Liquid dispensing device

A liquid dispensing device comprising:

• a dispenser which is positioned such that at least a portion of the dispenser is installed above a sink;
• a liquid processing module installed separately from the dispenser;
• a nozzle installed on the dispenser, the nozzle being configured to discharge a hot liquid generated in the liquid processing module to the sink;
• a user interface device installed on the dispenser, the user interface device being configured to receive a hot liquid discharge command from a user;
• a hot liquid tank installed inside the liquid processing module to generate the hot liquid;
• a hot liquid valve configured to control a flow of liquid into the hot liquid tank or a flow of liquid from the hot liquid tank;
• a common tube configured to receive liquid from the hot liquid tank;
• a liquid discharge valve installed on the common tube, the liquid discharge valve including a first outlet that is configured to discharge liquid from the common tube toward the nozzle and a second outlet that is configured to drain liquid from the common tube away from the nozzle;
• a temperature sensor installed on the liquid discharge valve;
• a drain tube connected to the liquid discharge valve to discharge the liquid drained via the second outlet of the first liquid discharge valve;
• and
• a controller configured to manage the hot liquid valve and the liquid discharge valve.

A liquid dispensing device comprising:

• a dispenser which is positioned such that at least a portion of the dispenser is installed above of a sink;
• a liquid processing module;
• a through-piping having a hollow shape, the through-piping being configured to pass through the sink vertically through a hole defined in the sink;
• an internal piping having a hollow shape, the internal piping being coupled to an upper side of the through-piping exposed to the upper side of the sink;
• and
• a nut including an expansion extension having a circular plate shape and positioned on a surface facing a bottom surface of the sink, a hexagonal body extending to a lower side of the expansion extension, and a pair of hooks extending from side surfaces of the body that are opposite from each other in a radial direction of the expansion extension, the nut being coupled to a lower side of the through-piping exposed to the lower side of the sink.

A liquid dispensing device comprising:

• a nozzle configured to discharge a sterilizing liquid having a sterilizing ingredient;
• a user interface device configured to receive a liquid discharge command or a liquid discharge stop command from a user;
• a sterilized liquid module configured to generate the sterilizing liquid;
• a sterilized liquid tube configured to connect the sterilized liquid module to the nozzle;
• at least one liquid discharge valve installed on the sterilized liquid tube to supply liquid from the sterilized liquid tube toward the nozzle or to drain liquid from the sterilized liquid tube;
• a drain tube connected to the liquid discharge valve to discharge the liquid drained from the sterilized liquid tube;
• and
• a controller configured to stop operation of the sterilized liquid module when a discharging of liquid from the sterilized liquid tube is completed according to an input received by of user interface device, the controller being configured to manage the sterilized liquid module and the at least one liquid discharge valve so that a liquid without the sterilizing ingredient is discharged to the nozzle or drained to the drain tube via the sterilized liquid tube.

A liquid dispensing device comprising:

• a nozzle configured to discharge a hot liquid;
• a user interface device configured to receive a hot liquid discharge command from a user;
• a hot liquid tank configured to generate the hot liquid;
• a hot liquid valve configured to control a flow of liquid introduced into the hot liquid tank;
• at least one tube configured to connect the hot liquid tank to the nozzle;
• at least one liquid discharge valve installed on the tube to supply the hot liquid introduced into the at least one tube toward the nozzle or to drain the hot liquid;
• a temperature sensor installed on the liquid discharge valve;
• a drain tube connected to the at least one liquid discharge valve to receive liquid discharged from the liquid discharge valve;
• and
• a controller configured to, when the hot liquid discharge command is input into the user interface device, manage the at least one liquid discharge valve to discharge liquid in the at least one tube to the drain tube when a temperature of the liquid is less than a set temperature before the hot liquid is discharged from the nozzle.

A liquid dispensing device comprising:

• a dispenser which is positioned such that at least a portion of the dispenser is installed to be exposed above a sink;
• a liquid processing module to generate a liquid outputted through the dispenser;
• a through-piping which passes in a vertical direction through a hole defined in the sink and on which a screw thread is positioned on an outer circumferential surface thereof, the through-piping having a hollow cylindrical body;
• an internal piping having a hollow shape, the internal piping being coupled to an upper portion of the through-piping that is exposed above the sink;
• a tube extending up to the dispenser from below the sink via the through-piping and a hollow of the internal piping;
• and
• a coupling nut having an expansion extension with a circular plate shape and positioned to face a bottom surface of the sink, a hexagonal body extending below the expansion extension, a plurality of hook members extending from side surfaces of the hexagonal body, and a coupling hole defined in a central region of the hexagonal body and having an inner circumferential surface on which a screw thread is positioned,
• wherein the coupling nut is coupled to a lower region of the through-member that is positioned below the sink.
