The first lifting cover includes a lifting gear extending in a vertical direction. The gear module includes a gear bracket coupled to the second lifting cover and a gear. The gear is rotated along the lifting gear by the operation of the lifting motor, and the second lifting cover is relatively moved with respect to the first lifting cover in the vertical direction.
Claims25
A liquid dispenser comprising:
- a case;
- and
- a dispenser coupled to the case,
- wherein the dispenser includes:
- a dispenser side cover coupled to the case;
- a stationary cover coupled to the dispenser side cover;
- an adjustable cover configured to be movable within the stationary cover;
- a lifting motor coupled to the adjustable cover,
- a gear module operably coupled to the lifting motor;
- and
- a dispenser nozzle installed in the adjustable cover and configured to discharge liquid,
- wherein the stationary cover includes a rack gear that extends in a vertical direction,
- wherein the gear module includes:
- a gear bracket attached to the adjustable cover;
- and
- a gear installed at the gear bracket and interconnected with the rack gear;
- and
- wherein in response to the gear being rotated along the rack gear by an operation of the lifting motor, the adjustable cover is moved with respect to the stationary cover in the vertical direction.
A control method of a liquid dispenser which includes a stationary cover and an adjustable cover provided inside the stationary cover and in which a dispenser nozzle configured to dispense liquid is installed, the control method comprising:
- detecting a height of a container placed on a tray through a plurality of sensors or receiving an external input through an input unit;
- and;
- operating a lifting motor configured to rotate a gear coupled to the adjustable cover when the height of the container is less than a predetermined height or when the external input is a command for moving the adjustable cover,
- wherein
- the gear is configured to move down along a rack gear attached to the stationary cover in a vertical direction such that the adjustable cover and the dispenser nozzle move downward from a first position to a second position which is lower than the first position, and
- when a command for liquid outflow is input through a liquid outflow input unit, liquid outflows from the dispenser nozzle.
