CONSTITUTION:When an operation switch 1 is pressed, operation of a bath is started, water in a bathtub is heated and the bath is ready. Adjustment of the heating-up temperature of the bath can be performed by a heating-up temperature adjusting switch 3. When the switch 3 is pressed, an indication lamp is lit and an aim of the heating-up temperature is displayed. When a protecting cover 6 is opened and a holding switch 5 is held under this state, this set state is held by a holding circuit. When the cover 6 is closed, the switch 5 becomes invisible, and even if a child touches the switch carelessly, a state which has been initially set is held and a matter that operation state varies does not happen. In addition to the above, release of the holding state can be performed by reopening the protecting cover and pressing the switch 5. |
