After circulating through a cleaning pipe provided with various cleaning processing means such as a sterilizing device for sterilizing, and then performing a cleaning process, the water is discharged into a bathtub again from a drainage pipe to continuously clean the bathtub hot water. In the cleaning device, the cleaning device is provided with a hot water temperature sensor for detecting and controlling the hot water temperature, and controls the heat retention of the heating device by detecting the hot water temperature of the hot water temperature sensor. At the time of reheating, when the hot water reaches the reheating setting temperature by detection, a reheating termination signal for ending the heating and heating of the reheating device is issued to perform the heat retention control by the heating device. The problem can be solved by the bathtub cleaning device.

[0009]

The present invention is constructed as described above. When the purifier is informed by the reheating input means to the cleaning device when the bath is ignited for reheating, the hot water is supplied. When the hot water temperature sensor detects that the temperature has reached the temperature set by the hot water temperature setting means, a signal such as a buzzer is generated from the reheating end alarm.

Accordingly, when a large amount of water is added to the bathtub during operation of the apparatus beyond the heating capacity of the electric heater disposed in the cleaning pipe, the manual operation is performed by the reheating device attached to the bathtub. Even so, prevent forgetting to turn it off and re-fire with peace of mind and quickly raise the temperature of the hot water to the set temperature, then keep the hot water at the set temperature for 24 hours by keeping it warm with an electric heater, and keep it clean and clean at any time Make sure you can bathe comfortably in the right temperature water.
