Abstract
A bathtub is equipped with a water supply tap (11) and a hydromassage system comprising a plurality of nozzles (12) on the walls of the bathtub (10) to each of which nozzles there are supplied flows of water and air coming from respective delivery (13) and supply (14) lines. The flow of water is taken off by means of a pump (15) having a suction line (17) connected to the container part of the bathtub (10), while the delivery line (13) is connected to the nozzles (12). The suction line (17) is connected to the container part of the bathtub (10) through the intermediary of a suction valve (16) which is normally closed, and each nozzle (12) comprises a plug (69) which is normally closed, so as to separate in a sealed manner the delivery (13) and supply (14) lines from the container part of the bathtub (10). With the plug (69) there is also associated a manually actuated conduit for partializing the flow. Provision is also made for sensors (27) sensitive to the level of the water in the bathtub (10) and to the pressure of the water in the delivery line (13), for controlling the automatic discharge of the hydromassage system, the operation of the tap (11) and the pump (15).
