INSTANTANEOUS HOT-WATER SUPPLIER

摘要

PURPOSE:To supply hot-water of a predetermined temperature at the beginning of using the hot-water immediately by a method wherein a main heat source machine is allowed to communicate with a terminal hot-water supplier through a hot-water supplying pipeline and the mixed flow of primary mixing section, mixing a flow from a bypass pipe guided from an inflow path with another flow from an outflow path, is guided to secondary mixing section, joining said mixed flow with the flow of a water supplying pipeline further, to deliver the hot-water while a check valve is provided in the bypass pipe. CONSTITUTION:A main heat source machine 1 is provided with a cool water inflow pipe 2, connected to a water service pipe or the like and an out-flow pipe 3 while a terminal hot-water supplier 4 is provided with a heating body 6 in a hot-water storage tank 5, to which an inflow path 7 is connected to the lower part and an outflow path 8 is connected to the upper part thereof. One end of a bypass pipe 10, branched from the inflow path 7 and provided with a check valve 9, is allowed to communicate with the outflow path 8 in primary mixing section 11. The check valve 9 permits a flow from the branch point (a) of the bypass pipe 10 and the inflow path 7 to the point (b) of primary mixing section 11 but never permit a reverse flow. According to this method, hot-water of a predetermined temperature may be obtained immediately when a cook is opened even in winter while a temperature distribution in the hot-water storage tank 5 may be improved.
