To provide a control method of a bath device provided with a bubbling function, which can control the flow of bathing water when a bubble generator and a water heater are simultaneously running, and can discriminate bathing water circulation easily and accurately.
This method is to drive a circulating pump 27 with a by-pass two-way type valve (by-pass water volume control valve) 29 shut totally closed, and to switch on a switch 31 for the bathtub side water flow for a prescribed period (15 seconds), and to carry out circulation discriminating at trial running and primary pipe arrangement air purging. When this method recognizes switching-on of the switch 31 of the bathtub side water flow for a prescribed period, then the method totally opens the by-pass two-way type valve 29 with the full speed and switches off the bathtub side water flow switch. After opening the by-pass two-way type valve 29, the method closes the same valve with dead slow speed and, when the bathtub side water flow switch is on, the method shuts up the by-pass two-way type valve 31. When the bathtub side water flow switch is recognized to be continuously on for a prescribed period (15 seconds), the method memorizes the extent of opening of the by-pass two-way typed valve at this moment as the most suitable extent of the opening. Further, the method memorizes the most suitable extent for each capacity if the circulating pump 27 has a variable pumping capacity.
