Problems solved by technology

However, in the existing heat exchanger, impurities such as scale will accumulate due to long-term use.
Therefore, when a large amount of foreign debris attached to the heat exchanger is discharged from the heat exchanger, it will cause clogging of the cleaning nozzle, so that the cleaning water cannot be sprayed.
As a result, the life of the sanitary cleaning device is shortened
[0009] In addition, since it is difficult to miniaturize the existing heat exchanger, it is also difficult to miniaturize the sanitary cleaning device using the heat exchanger.

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...
