Abstract

A heat exchanger is constituted of a substantially circular cylindrical sheathed heater, a substantially circular cylindrical case, and a spiral spring. The sheathed heater is received in the case, and the spring is wound on the outer peripheral surface of the sheathed heater. Thus, a spiral flow path is formed in a space surrounded by the outer peripheral surface, inner peripheral surface of the case, and spring. The spring functions as a flow speed changing mechanism, turbulence producing mechanism, flow direction changing mechanism, and impurity removing mechanism. A water inlet and a water outlet are arranged on a side surface of the case, at positions eccentric from the center axis of the case.

Description

technical field

[0001] The invention relates to a heat exchanger for heating fluid and a cleaning device with the heat exchanger. Background technique

[0002] In a sanitation washing device for washing parts of the human body, a clothes washing device for washing clothes, and a dish washing device for washing dishes, a heat exchanger for heating water is used (for example, refer to Patent Document 1 ).

[0003] Figure 48 is a schematic sectional view of a conventional heat exchanger. Such as Figure 48 As shown, this heat exchanger has a double-layer pipe structure composed of a cylindrical base pipe 801 and an outer cylinder 802 . A heater 803 is provided outside the substrate tube 801 . A spiral core 805 is inserted into the inner hole 804 of the substrate tube 801 . The cleaning water flows along the thread teeth 806 of the spiral core 805 in the inner hole 804 of the substrate tube 801 . At this time, warm water is generated due to heat exchange between the heater...
