Title: Hot Tank for Directly Draining Type Water Purifier
Inventor: LEE DONG JUN
IPC: B67D1/00
Filed: 2018-02-28
Abstract: The present invention relates to a hot water tank for a direct water supply type water purifier. Since an air chamber, which does not store water, is formed in an upper space of a tank body due to a placement structure of inflow and discharge pipes, water in the tank body can be fundamentally prevented from flowing backwards through an air vent pipe. Since the water in the tank body is kept at a constant water level in accordance with the placement structure of the inflow and discharge pipes, the mixture of the water with supply pressure of the inflow pipe can be relatively small, only the water on the top layer can be discharged through the discharge pipe, and the water can be discharged after being sufficiently heated, so even if hot water is continuously collected, hot water having the same temperature can be continuously supplied, which can lead to doubled stability and convenience in hot water supply. Moreover, since the separation of the tank body is convenient, even a nonskilled person can easily clean the internal space of the tank body, and leak prevention and assembly convenience can be improved even in terms of reassembly.
