INSULATION TANK FOR HOT WATER APPARATUS

摘要

PURPOSE: A heat insulation tank for a hot water dispenser is provided to improve airtightness by surface-contacting a cap and a connection part of a tank in multiple locations. CONSTITUTION: A heat insulation tank for a hot water dispenser comprises a vacuum vessel unit(10), a cap(20), a heat exchanging unit, and a heat insulation unit(600). The vacuum vessel unit is formed an internal space and comprises a vessel body(100) and a first connection part(310). The vessel body is connected to the first connection part and a vacuum section(101) including a heater(40) is formed around the periphery of the vessel body. The cap has a second connection part(410) coupling to the first connection part and it is coupled to the vacuum vessel unit to seal the internal space. The heat exchanging unit is placed on the cap and the heat insulation unit encloses the cap, the first and the second connection part.
