Abstract
This invention relates to an air turbulence massage device having a control device with a blower unit and a turbulence matting which can be placed in a bathtub. The turbulence matting can be connected with the blower unit outlet by means of an air tube. The turbulence intensity, using a preset program, can be adjusted and changed between a lower and an upper value by varying the rotational speed of the blower unit. To achieve siultaneous switching times with the turbulence process, this invention provides that the lower value is preset as a minimum pressure value which is enough to overcome a counter-pressure predetermined by a normal water level in the bathtub. The upper value is preferably preset as an adjustable maximum pressure value. At predetermined time intervals, the turbulence intensity can be abruptly switched between the predetermined minimum pressure value and the predetermined maximum pressure value and/or can be changed at predetermined time intervals which alternately increase and decrease the turbulence intensity.
