BATH DEVICE

PURPOSE:To prevent noise from being generated when a circulation pump is driven by a method wherein water in an over-flow chamber is sucked at a venturi part and the water is discharged into a bath tub together with circulating water. CONSTITUTION:Bat tub water is circulated through a bath returning pipe 21, an additional heating boiler 30 and a bath going pipe 22 under a driving operation of a circulation pump 41. A negative pressure is generated at a venturi part 23 formed at the bath going pipe 22 under this circulation. Accordingly, remaining water in an over-flow chamber 70 is sucked into the bath going pipe 22 through a discharging pipe 73 connected to a negative pressure generating part of the venturi part 23 and further fed into a bath tub 10 together with circulation water. That is, the remaining water in the over-flow chamber 70 is directly sucked into the bath going pipe 22 without passing through the circulation pump 41 or the bath returning pipe 21 and then the remaining water is discharged into the bath tub 10. With such an arrangement as above, air flowed from the over-flow chamber 70 is not sucked into the bath returning pipe 21 or the circulation pump 41 and occurrence of noise can be prevented when the circulation pump 41 is driver.
