In step S10, control device 10 uses water level sensor 23 to detect fluctuations in water level in bathtub 1 from completion of hot water filling to discharge of bathtub water. The control device 10 takes the water level in the bathtub 1 after the completion of hot water filling as a reference, considers the state in which the water level rises above the reference as the bathing time, and detects the number of bathers and the bathing time on the day from the way the water level fluctuates. . The control device 10 estimates the degree of contamination based on the detected number of people in the bath and the total bathing time, and proceeds to step S11. The control device 10 is based on the idea that the more the number of people taking a bath, the greater the degree of dirt adhering to the bathtub 1, and the longer the total bathing time, the greater the degree of dirt adhering to the bathtub 1. to estimate

In step S11, the control device 10 calculates the supply amount of the cleaning agent and the supply amount of the rinsing water in the bathtub cleaning operation. The amount of cleaning agent supplied and the amount of rinsing water supplied are determined from the degree of contamination estimated based on weather information or date/installation area information in steps S8 and S9, and the degree of contamination estimated based on water level fluctuations in step S10. It is determined. After that, the control device 10 calculates an appropriate supply amount of cleaning agent and rinsing water for the estimated degree of contamination, and performs a bathtub cleaning operation.

In the past bathtub cleaning operation, if the controller 10 has learned data about the amount of detergent supplied and the amount of rinse water supplied with respect to the degree of contamination, the controller 10 reads the learned data into the amount of detergent supplied. to reflect the amount and rinse water supply. When the bathtub cleaning operation is completed, the process proceeds to step S12.

In step S12, the user operates the remote control device 11 to input feedback as to whether or not the amounts of detergent and rinse water were appropriate for the degree of contamination in the bathtub cleaning operation. After completing the input, the process proceeds to step S13.

In step S13, the control device 10 is made to read the data entered by the user in step S12 regarding the amount of cleaning agent and rinsing water with respect to the degree of contamination. The data input here is recorded in the control device 10 as learning data and reflected in the next and subsequent bathtub cleaning operations. For example, if the user inputs that the dirt is not sufficiently removed with respect to the amount of cleaning agent and rinse water supplied in the bathtub cleaning operation, the control device 10 will perform the next bathtub cleaning operation. , increase the supply of detergent and rinse water.

The bath hot water supply system 100 capable of determining the optimum amount of cleaning agent and rinsing water to be supplied based on weather information or water level fluctuations in the bathtub 1 and feedback input from the user has been described above. It is also possible to control so as to always supply a constant amount of cleaning agent and rinse water without using the data calculated in . By operating the remote control device 11, the user can determine whether to calculate an appropriate amount to supply or to always supply a constant amount.
