Since the force of pushing the detecting body 47 downward via the magnetic field may be weakened or may be rapidly reduced, the spring 48 pushes it upward, and the magnetism of the detecting body 47 does not act on the reed switch 45. This signal is sent to the control device through the signal line 46, and when the water shortage is detected and the water shortage occurs due to the continuous use of the cleaning device, the display device 33 is clogged with the contents of the filtration tank or the activation tank. The decrease in purification and activation ability is finely judged and a message indicating that it is time to wash with water is displayed.

熱等の問題を解決できるというという効果が得られる。As described above, according to the present invention, the arm portion having the tray for receiving the circulating hot water near the lower end is suspended from the vertically movable detector of the water flow sensor of the heat insulation cleaning device. Since the sliding surface between the movable part of the detector and the shaft part is located above the circulating hot water, adhesion and deposition of scales and suspended matter on the sliding surface of the float and shaft part, as in the conventional example, The problem of clogging such as stones and fragments of activated carbon was solved, and the saucer part of the detector of the water flow sensor in the circulating hot water was constantly deformed and vibrated by the running water. Even if there is a blockage of activated stone or activated carbon between the saucer and the inner wall of the water flow sensor case, it will be carried away into the circulating hot water,
Since the water flow sensor always operates normally and the flow rate of hot water can be detected without malfunction, it is possible to correctly judge the decrease in flow rate or the rapid decrease in flow rate due to clogging of the filtration tank or activation tank during long-term use of the cleaning device. It is possible to purify filters, activated stones, activated carbon, etc., and to inform the user before the activation capacity drops to a certain level, and to wash these filter media based on these judgment results. In the case of 1, the effect of being able to solve the problems such as the idle operation of the circulation pump and the abnormal overheating of the heat retention heater in the conventional example is stopped.
