Abstract
A liquid dispenser, such as water purifier, may have a soft insulation material installed in a space between a rigid insulator surrounding a cold water tank assembly and a cover, the cold water tank accommodating a coolant therein and having a passage through which water passes to be cooled through a heat exchange with the coolant, and the soft insulation material thereby removing the space and improving a cooling effect.
Claims19
A liquid dispenser comprising:
- a case including a plurality of covers;
- a cold liquid tank assembly provided in the case and configured to accommodate a coolant therein and to cool a liquid using the coolant;
- a first insulator surrounding an outer surface of the cold liquid tank assembly;
- and
- a second insulator provided in a space formed between the first insulator and a first cover positioned adjacent to the cold liquid tank assembly among the plurality of covers,
- wherein the first insulator is relatively more rigid than the second insulator,
- wherein the second insulator insulates the cold liquid tank assembly and reduces vibration and noise when the liquid dispenser is driven, and
- wherein the first insulator and the second insulator are made of Polyurethane (PU).
