Device for letting off residual steam and water from the heating unit of a hot beverage machine

摘要

A hot beverage machine includes a heating unit having a fresh water intake. A fresh water line supplies fresh water to the fresh water intake of the heating unit. A residual fluid line is coupled to the fresh water intake of the heating unit through an on-off valve for conducting fluids to a collection container. A device for letting off residual steam and residual water from the heating unit includes a heat-exchanging and heat-storing condenser having a residual line section coupled to the residual fluid line, a fresh water line section coupled into the fresh water line and a heat storing medium that is connected for conducting heat between the residual line section and the fresh water line section.
