<p>PROBLEM TO BE SOLVED: To provide a bath device capable of easily detecting a state where a lid is not placed on a bathtub.SOLUTION: In a bath device, a bathtub 6 and a heat exchanger 19 for a bath are connected by a bath circulation circuit 23 including a bath circulation pump 21 in the middle, and a bath temperature sensor 24 for detecting a temperature of bathtub water is provided at the bath circulation circuit 23. The bath device includes hot water supply control means 38 which detects bathtub water temperature by the bath temperature sensor 24 at every predetermined time, and when the bathtub water temperature is at predetermined temperature, it drives the bath circulation pump 21 and makes the heat exchanger 19 for a bath perform an automatic heat-retaining operation for heating the bathtub water up to a bath preset temperature. When the detection temperature of the bathtub water by the bath temperature sensor 24 is lower than the previous heat-retaining start temperature by predetermined temperature, the hot water supply control means 38 determines that a lid 7 is not placed on the bathtub 6, and operates notification means 39.</p> |
