CYLINDRICAL PIPE HEAT EXCHANGER AND BIDET USING IT

摘要

PROBLEM TO BE SOLVED: To secure safety by facilitating wiring in a heat exchanger with reduced heat capacity. SOLUTION: A cylindrical pipe 1, a resistor 4 that is formed on the surface of the pipe and generates heat by applying a voltage, and at least three terminals that connect wires and include a plurality of terminals for applying a voltage to the resistor are provided.
