PROBLEM TO BE SOLVED: To provide an automatic bath device capable of preventing waste of hot water to be supplied to a bathtub and energy necessary for heating the hot water by promptly determining an opening state of a drain plug of the bathtub after starting a hot water filling process.SOLUTION: An automatic bath device includes an operation portion 10 operated by flow of hot water/water discharged from a bathtub Y1 to a drain passage Y4 connected to the bathtub Y1, a power generation portion Z generating power with the operation of the operation portion 10, a radio signal transmission portion S operated by electric power V generated by the power generation portion Z, and wirelessly transmitting a hot water/water discharge signal Sa when the electric power V is supplied from the power generation portion Z, and a radio signal reception portion receiving the hot water/water discharge signal Sa wirelessly transmitted, and transmitting the hot water/water discharge signal Sa to a hot water/water supply control portion. The hot water/water supply control portion determines opening of a drain plug Y3 for opening and closing the drain passage Y4, when receiving the hot water/water discharge signal Sa from the radio signal reception portion in executing the hot water filling process.SELECTED DRAWING: Figure 2 |
