Title: Gas combustion type derect contact water boilr
Inventor: JIYON FURANSHISU ROKETSUTO
IPC: F24H1/28
Filed: 1990-03-15
Abstract: PURPOSE: To supply hot water immediately to a user as desired when a user's valve is opened, by providing a water supply means for transferring heat from products of combustion to water to obtain hot water, and a conduit means for continuously moving and conveying the hot water along a passage. CONSTITUTION: A ball cock 30 is opened so that water from the main pipe of city water enters an upper chamber 10 through a distributing means 28 and then flows downward along a passage into which a heat transfer means 26 is inserted. In the heat transfer means 26, the water is heated by hot combustion product rising from a burner 54. As long as a controller 70 is operated, a pump 42 is continuously operated. Thus, when a user's valve 46 is opened, hot water can be always instantaneously supplied to a user. On the other hand, when the user's valve 46 is closed, water from a reservoir 24 is recirculated through a conduit 48 and a pressure relief valve 52. Thus, the water is reheated in the heat transfer means 26 and the reservoir 24. Then, the water is maintained substantially at a prescribed temperature T1 until the user's valve 46 is next opened.
