Separable hot water tank

Abstract

A hot water tank mounted on a hot/cold water dispenser, a water purifier, a vending machine, or the like, is provided. The separable hot water tank has a separable structure to facilitate its cleaning and is provided with a vacuum space formed on an outer wall thereof to improve heat resistance. In the separable hot water tank, a cover is separably engaged with a body provided with a water storage space formed therein. A cover screw part and a body screw part, which are formed on the cover and the body, respectively, are screw-engaged with each other, or a fastening part provided on the cover and a locking part provided on the body are separably engaged with each other. A sealing means is interposed between the body and the cover to seal the interior of the hot water tank.
