Coway has been granted a patent for a method of selecting a cleaning course based on cleaning and emotional factors. The method involves assigning different cleaning courses for various combinations of cleaning factors, calculating emotional weights based on preset cleaning weights, and selecting second cleaning courses based on emotional weights. The cleaning factors include water pressure, temperature, sterilization, and more, while emotional factors include cleaning precision, range, and sensitivity. Different reference values are stored for each cleaning factor, and a corresponding cleaning course is selected based on the emotional weight.

A recently granted patent (Publication Number: US11773578B2) describes a method for selecting a cleaning course in a bidet apparatus. The method involves considering both cleaning factors and emotional factors to determine the most suitable cleaning course. The cleaning factors include water pressure, water temperature, sterilization, spraying time period, spraying area, air injection pattern, and reciprocating speed of the cleaning module. The emotional factors include the degree of change in cleaning, cleaning precision, cleaning range, and cleaning sensitivity.

The method consists of several steps. First, different cleaning courses are assigned for various combinations of cleaning factors. Then, preset cleaning weights are given to each cleaning factor. An emotional weight is calculated for each emotional factor based on the cleaning weights assigned to the cleaning factors. Finally, a second cleaning course is selected for each emotional factor using a preset method based on the calculated emotional weight.

The emotional weight calculation takes into account the cleaning weights of the cleaning factors included in the assigned cleaning courses. If the emotional weight exceeds a preset reference value, the corresponding cleaning course is selected as the second cleaning course.

The patent also includes claims for bidet apparatuses that apply the method for selecting a cleaning course. These bidet apparatuses consist of a toilet seat, a main body installed in the seat, a pivotable seat, a pivotable cover, a cleaning module to spray water, and a control unit to control the cleaning factors. The selected second cleaning courses are performed by the cleaning module.

Overall, this patent presents a method for selecting a cleaning course in bidet apparatuses that takes into account both objective cleaning factors and subjective emotional factors. By considering these factors, the bidet apparatus can provide a more personalized and effective cleaning experience for users.
