Hand held tap water powered water discharge apparatus

Apparatus for use with a water tub having a tap water source supplying pressurized water for selectively discharging a hydromassage stream or a shower water spray, said apparatus comprising:

• a housing configured to be held in a user's hand, said housing defining an internal cavity having a supply water inlet, a tub water inlet, and a hydromassage outlet;
• a tub water passageway in said housing having (1) an externally accessible tub water supply entrance and (2) a tub water supply exit means communicating with said cavity tub water inlet for supplying tub water thereto;
• a tap water supply passageway in said housing having (1) an externally accessible water supply entrance and (2) a water supply exit;
• a plurality of shower holes defined in said housing;
• user operable valve means for selectively directing water flow from said water supply exit into either said shower holes or said cavity supply water inlet;
• and
• restricted cross-section orifice means located between said water supply exit and said valve means for limiting supply water flow rate and for increasing the velocity of water flow into said cavity to entrain tub water supplied thereto.

Apparatus for use with a tap water source supplying pressurized water for selectively discharging a hydromassage water stream or a shower water spray, said apparatus comprising:

• a first housing including a water supply passageway having a water entrance and a water exit, and an air supply passageway having an air entrance and an air exit;
• a second housing including a cavity having a water inlet, an air inlet, a hydromassage outlet, and a shower outlet;
• means mounting said first housing for movement, relative to said second housing, between first and second positions;
• said mounting means in both said first and second positions orienting said first housing water exit in communication with said second housing water inlet for introducing a high velocity tap water flow into said cavity;
• said mounting means in said first position orienting said first housing air exit in communication with said second housing air inlet for supplying air to said cavity for entrainment by said high velocity flow;
• valve means mounted downstream from said first housing water exit and air exit for directing a water stream from said cavity through said hydromassage outlet when said first housing is in said first position and through said shower outlet when said first housing is in said second position;
• a member defining a hydromassage passageway having an entrance orifice and a discharge orifice;
• and
• means supporting said member with its entrance orifice communicating with said hydromassage outlet for movement of said discharge orifice along a travel path in response to a water stream discharged therefrom.

• said second housing defining a plurality of spaced externally opening shower holes;
• means mounting said first housing for movement, relative to said second housing, between first and second positions;
• said mounting means in said first position orienting said first housing tap water exit in communication with said second housing shower holes for discharging a water spray therefrom;
• said mounting means in said second position orienting said first housing tap water exit in communication with said cavity tap water inlet for introducing a tap water flow of sufficient velocity into said cavity to entrain tub water supplied thereto;
• a member defining a hydromassage passageway having an entrance orifice and a discharge orifice;
• and
• means supporting said member with its entrance orifice communicating with said hydromassage outlet for movement of said discharge orifice along a travel path in response to a water stream discharged therefrom.

• a tap water supply passageway in said housing having (1) an externally accessible water supply entrance and (2) a water supply exit;
• restricted cross-section orifice means located adjacent to said cavity supply water inlet for increasing the velocity of water flow into said cavity to entrain tub water supplied thereto;
• a member defining a hydromassage passageway having an entrance orifice and a discharge orifice;
• means mounting said member in said housing with said entrance orifice communicating with said cavity hydromassage outlet for discharging a hydromassage stream from said discharge orifice;
• said mounting means including means supporting said member for movement of said discharge orifice along a travel path in response to said hydromassage stream being discharged therefrom;
• a membrane having front and rear faces;
• and
• means mounting said membrane on said housing with said rear face proximate to said discharge orifice travel path for enabling said hydromassage stream to impact against said rear face without restricting the outflow from said discharge orifice.
