Definitions

  • HYDROMASSAGEJTUB AND AIR INDUCTION SYSTEM THEREFOR My invention relates to hydromassage equipment and more particularly to a hydromessage tub and air induction system therefor.
  • Hydromessage equipment functions primarily by ereating a jet stream with numerous air bubbles entrained therein, such bubbles exploding upon impact of the jet stream against the body. to produce a gentle massage action, along with the impact of the water itself against the body.
  • Air is usually entrained in the jet stream through a pipe or tube which is exposed at one point to atmosphere, and at another point to flow of water through a nozzle to induct air into the jet stream.
  • FIG. I is a plan view of my improved hydromassage tub with my improved air induction system incorporated therein;
  • FIG. 2 is a schematic view depicting the general layout of the water and air systems associated with the tub of FIG 1;
  • FIG. 3 is a view in section through a conventional type jet head assembly
  • FIG. 4 is a plan view of the air induction control means of the present inventipn
  • FIG. 5 is a view in section, taken in the plane 55 of FIG. 4;
  • FIG. 6 is a view in section taken in the plane 6-6 of FIG. 5.
  • a tub I of substantially rectangular shape having a jet head assembly 3 installed in each corner thereof, the tub including side walls 5, 7 preferably of slightly greater length than the end walls 9.
  • a peripheral apron l3 surrounds the tub walls in spaced relationship thereto to create a peripheral chamber, which not only houses the jet head assemblies, but also a pump 17 in one corner 18 and all piping associated with the system.
  • Filling the tub may be from a faucet installed above in an adjacent room wall and emptying may be accomplished through a controllable drain in the floor of the tub, neither the faucet nor the drain being involved in the present invention.
  • Each jet head assembly may be of conventional design, such for example, as illustrated in FIG. 3, wherein a housing 19 of generally frusto-conical form having an end wall 21 at one end and amounting flange 23 at its other end, the end wall including a hollow hemispherical central portion 25 flow connecting with an axial extension 27 for connection to a source of water, and a passageway 29 at substantially right angles thereto for connection to a source of air.
  • a spherical component 31 swivel mounted in the hemi-spherical central portion of the end wall, has an integral axial extension 33 which, together with the spherical component, has an axial passageway 35 therethrough which is threaded for adjustable installation of a nozzle 37 which in turn, is sealed adjacent its inner end to the hemi-spherical portion by an O-ring 39, the longitudinal passageway flow connecting with the water intake extension 27 via an aligned opening 41 in the hemi-spherical central portion.
  • the nozzle is provided with one or more radial openings 43 in its wall, and provision is made for flow coupling the air intake passageway 29 to the interior of the nozzle by way of these openings.
  • All four corner jet heat assemblies are supplied in parallel with water from the pump, the water being returned to the pump via a return opening 47 in the proximate comer of the tub, to which opening, the suction line of the pump is coupled.
  • Air control to the jet head assemblies is provided from a substantially horizontal but preferably slightly sloping panel 49 installed preferably in that corner of the tub, which houses the pump, and above the proximate jet heat assembly.
  • Two control knobs 51, 53 are installed in this panel, one in control of the air to the jet head assemblies at one end of the tub, and the other in control of air to the other two jet heat assemblies at the opposite end,
  • An appropriate scale or indicia 55 on the panel in association with tlhe control knobs, will enable intelligent control of the air supply to the jet head assemblies.
  • These two control knobs are components of an air control unit comprising a housing 57 formed of side walls, closed at one end by a floor 59 and at its other end by an end wall 60 upon which the panel 49 rests and is retained by appropriate fastening means.
  • a pair of air tubes 61, 63 Installed in and extending through the floor of the air control unit, are a pair of air tubes 61, 63, a portion of each extending outside the housing for coupling to an air line 67, 69 respectively, from which to supply air to two of the jet head assemblies and a portion of each extending within the housing.
  • each air tube within the housing has an opening 71 adjacent its edlge. Telescoping this end of each air tube is a rotatable cap 73 having a matching opening, which by rotation of the cap as a valve, can he made to move into and out of registry with the associated opening in the tube, and to varying degrees.
  • Each tube and associated cap thus constitutes a valve assembly for determining permissible air intake.
  • Rotational adjustment of each such cap valve is remotely controlled from one of the knobs through a coupling rod 75 connecting the knob to the associated cap, whereby rotational adjustments of the knob will effect corresponding rotational adjustments of the valve cap or air intake valve.
  • the housing is exposed to atmosphere by way of an air intake nozzle 79 flow connecting with a side wall of the housing.
  • this air intake nozzle is of slightly increased internal diameter to provide a chamber 81 in which to house a light weight plastic ball 83 of the pingpong type, for limited movement with respect to a soft rubber lip valve seat 85 installed at the extreme end of the nozzle and with respect to which, the ball will act as a valve.
  • the air intake nozzle being common to both air aupply systems, the one ball valve will serve to protect both systems against possible flooding of the surroundings, should any of the jet nozzles associated with either of the systems be blocked.
  • a hydromassage system comprising a jet head assembly including a jet nozzle having means for connection to a source of water under pressure, means for introducing air into said nozzle in response to flow of water therethrough, said means for introducing air including an air passageway exposed at one point to atmosphere and at another point to such flow of water, and means permitting entrance of air into said air passageway and flow therethrough to such flow of water through said nozzle, and adapted to block flow of water through said air passageway in the reverse direction in the event discharge of water through said nozzle be blocked.
  • a hydromassage system in accordance with claim 1 characterized by means in said air passageway, normally only partially closing the same to permit flow of air therethrough from atmosphere toward said nozzle, but responsive to flow of water in the reverse direction, for blocking said passage to How of water therethrough in said reverse direction.
  • a hydromassage system in accordance with claim 2 characterized by an adjustable air intake valve assembly in said air passageway intermediate said nozzle and said means for permitting flow of air in the one direction and blocking flow of water in the reverse direction.
  • a hydromassage control unit for a system for independently controlling air flow to different jet head assemblies in such system comprising a housing having side walls, a floor at one end and an end wall at the other end, a pair of air tubes extending through said floor with a portion of each air tube extending outside the housing for coupling to an air line to a jet head assembly, and a portion extending into said housing and terminating in an adjustable air intake valve assembly, an air intake nozzle mounted at one end in a wall of said housing with its other end exposed to atmosphere, and means for controlling each of said air intake valves independently of.the other from outside of said housing.
