FLUID HEATING DEVICE AND CLEANING DEVICE USING THE SAME

摘要

A cleaning water inlet for receiving cleaning water is provided in the upper surface on one end side of a case body section of a fluid heating device. A cleaning water outlet for sending out heated cleaning water to a pump is provided in the upper surface on the other end side of the case body section. A linear sheathed heater is installed so as to penetrate the inside of the case body section. A spring is spirally wound on the outer peripheral surface of the sheathed heater. A flow path is formed by the outer peripheral surface, the spring, and the inner peripheral surface of the case body section. The flow path is spirally formed with the length direction of the case body as the axis.
