Abstract
A liquid dispenser may include a container having an upper opening, a pump provided in the container, a pipe through which liquid discharged from the pump is transferred, a top plate having an upper surface over which liquid flows, a filter assembly provided below the top plate, a base provided below the container, and a thermoelectric element provided in the base to cool the liquid in the container.
Claims16
A liquid dispenser, comprising:
- a container configured to store liquid and having an upper opening;
- a pump having an inlet to suction liquid stored in the container and an outlet to discharge the liquid;
- a lid seated on the container to cover the upper opening and having a hole through which liquid discharged from the pump flows;
- and
- a base to support the container, the base including:
- a fan having an intake and an outtake,
- a suction grill through which ambient air is suctioned via the intake of the fan,
- a plurality of exhaust vents through which air from the outtake of the fan is discharged, and
- a fan housing to which the fan is mounted, the fan housing having a pair of vertical walls, and at least one inclined surface which is provided between the pair of vertical walls and is inclined outward from a top end to a bottom end, the bottom end being closer to the exhaust vents than the top end,
- wherein an end of the at least one inclined surface is connected to one of the pair of vertical walls, and another end of the at least one inclined surface is connected to another one of the pair of vertical walls,
- wherein the liquid dispenser further comprises a heat sink provided on the at least one inclined surface and between the pair of vertical walls,
- wherein the at least one inclined surface includes first and second inclined surfaces that are provided at a first side of the fan housing and a second side of the fan housing opposite the first side,
- wherein the pair of vertical walls are provided at a third side of the fan housing and a fourth side of the fan housing opposite the third side,
- wherein the exhaust vents are provided in a side surface of the base, and both the first and second inclined surfaces of the fan housing face the exhaust vents,
- wherein the heat sink is placed on the fan housing so as to have a vertical position corresponding to a vertical position of the exhaust vents provided in the base,
- wherein the liquid dispenser further comprises a Peltier device mounted on the heat sink,
- wherein the heat sink comprises a heat dissipation plate, and radiating fins connected to the heat dissipation plate,
- wherein the radiating fins overlap with the exhaust vents in a horizontal direction, and
- wherein the radiating fins are positioned on top of both the first and second inclined surfaces.
