Title: Electric instantaneous water heater
Inventor: KOMATSUDA JUNJIRO
IPC: F24H1/10
Filed: 1987-05-29
Abstract: PURPOSE:To enable constitution of a heat exchanger so that the thickness thereof is decreased and to provide an instantaneous water heater which can be mounted in an arbitrary place on a wall surface and a floor surface, by a method wherein a planar heating element is placed on the outer surface of a thin type plate hate exchanger provided at its interior with a bent flow passage. CONSTITUTION:The surface of a heat exchanger 1 to which a planar heating element 6 is laminated is integrally moulded by a heat resistant synthetic resin layer 7 for coverage to constitute an electric instantaneous water heater. With a flow rate regulating valve 8 opened, a pressure switch PS is actuated by means of the pressure of water flowing through an inflow pipe 4. The planar heating element 6 is energized through the pressure switch PS, temperature switches TS1 and TS2, and a power control device 13, and the planar heating element 6 generates heat to uniformly heat a heat exchanger surface. The temperature of hot water flowing through an outflow pipe is detected by a temperature detector TH, and is sent to a comparator 12 where the temperature is compared with temperature set by a temperature setter 11, and the power control device is actuated to cause the flow of hot water the temperature of which is normally regulated to a set value. The so constituted electric instantaneous water heater is of a thin type, and therefore it can be mounted in a wall surface, e.g. the floor surface and the ceiling of a bath room.
