Definitions

  • the present invention relates to improvements in such hydrotherapy apparatus whereby a portable hydrotherapy unit is provided in which the housing is divided into two rigid portions connected together by a flexible hose whereby one of the rigid portions may be mounted on the floor outside of a bathtub While the other rigid portion is positioned inside of the bathtub with two rigid portions connected together by the flexible hose extending over the side wall of the tub.
  • This apparatus may be handled very easily as a portable hydrotherapy unit since the heaviest components of the unit may be mounted outside of the bathtub and need not be lifted into the bathtub; additionally, the unit is adapted for use in a wide variety of bathtubs where the rigid portion of the housing which is mounted in the bathtub occupies very little space in the bathtub.
  • the construction of the present portable hydrotherapy unit provides even additional safety by removing the electrical components of the apparatus to a position remote from the bathtub and there-by further reducing the possibility of failure of the apparatus through hydraulic short circuits.
  • the apparatus is provided with improved means for priming the pump in the unit and improved safety means for preventing operation of the unit when it is not properly primed.
  • FIG. 1 is a view in side elevation of improved portable hydrotherapy apparatus constructed in accordance with the principles of this invention with the apparatus shown mounted in a bathtub;
  • FIG. 2 is a vertical sectional view on an enlarged scale taken along the plane indicated at 2-2 in FIG. 1;
  • FIG. 3 is a vertical sectional view taken along the plane indicated at 33 in FIG. 2;
  • FIG. 4 is a horizontal sectional view, on an enlarged scale, taken along the plane indicated at 4-4 in FIG. 1, and
  • FIG. 5 is a vertical sectional view through the apparatus of FIG. 4.
  • the portable hydrotherapy apparatus illustrated therein includes an outer pump housing portion mounted on the floor outside of the bathtub 12 and connected by a flexible conduit 14 to an inner nozzle housing portion 16.
  • the nozzle housing 16 has a rigid body 18 to the back of which is mounted a rubber suction cup 20 by means of a plate 22 and screws 24 (FIG. 2) whereby the nozzle housing 16 is mounted on the end wall 26 of the bathtub.
  • a perforated screen 28 is mounted around the periphery of the nozzle housing body 18 by means of screws 30 with the screen providing an inlet opening into the body 18 for flow of fluid from the bathtub into a vacuum inlet chamber 32 in the body 18.
  • the body 18 has interior cast walls 34 which provide a pressure chamber 36 in the body 18 communicating with a discharge nozzle assembly 38 as indicated hereafter.
  • the vacuum and pressure chambers 32 and 36 respectively terminate in concentric vacuum and pressure fittings 40 and 42 at the top of the body 18.
  • the flexible portion 14 of the housing is made of concentric outer and inner hoses 4-4 and 46 which are connected to the fittings 40 and 42 respectively, the inner hose 46 being made of conventional pressure hose stock adapted to convey liquid under pressure, and the outer hose 44 being made of conventional vacuum hose stock the periphery of which is provided with helical corrugations which prevent the hose from collapsing when subjected to interior vacuum.
  • the nozzle assembly 38 mentioned above includes a generally spherical portion 48 supported on a frustospherical seat on the wall elements 34 by means of a cap 50 which is mounted on the body 18 by bolts 52 (FIG. 1), the cap 50 also having an interior frusto-spherical seat as seen in FIG. 2 so that the spherical portion 48 of the nozzle assembly may be pivoted in the body 18 in both horizontal and vertical planes perpendicular to the wall 26 of the bathtub.
  • a slot 54 is provided in the spherical portion 48 of the nozzle assembly and receives a pin 56 which is mounted in the body 18 limiting pivotal movement of the nozzle assembly 38 in a vertical plane.
  • a central fluid passageway is provided by the spherical member 48 communicating with the pres-sure chamber 36, and a boss 58 is mounted in this fluid passageway by web elements (not shown) with the boss 58 providing a valve seat 60.
  • An elongated nozzle member 62 is threadedly mounted in the member 48 for movement toward and away from the seat 60.
  • the nozzle member 62 has a venturi throat which communicates through ports 64 with an air chamber 66 in the member 48 surrounding the nozzle 62..
  • the air chamber 66 communicates through a lateral opening 68 in the member 48 with a vertical air supply tube 70 (FIG. 3) which carries at its upper end an adjustable air supply cap '72.
  • water enters the body 18 through the screen 28 and hence flows through the vacuum chamber 32 to the interior of the vacuum hose 44. Water is sucked through the vacuum hose 44 to the pump housing 10 and is returned under pressure through pressure hose 46 as explained hereinafter.
  • the water delivered under pressure from hose 46 enters pressure chamber 36 and passes through the adjustable opening between valve seat 60 and nozzle 62 and hence through the venturi opening in the nozzle 62 where it draws air into the nozzle through the apertures 64.
  • the pump housing 10 includes a base portion 74 having interior walls 76 which define an intake chamber 78 and a discharge chamber 80 which are connected by fittings 81 and 83 respectively to the vacuum and pressure hoses 44 and 46.
  • a rotary impeller 82 is mounted on a central shaft 84 which is driven by an electric motor in the upper portion of the housing through a bearing 86 and water seal 88. When the impeller 82 is driven in rotation, it impels Water from its eye through its peripheral discharge 90, hence through diffuser vanes 92 to a peripheral pressure chamber 94. In the pressure chamber 94 water flows upwardly to an upper passageway 96 through which the water flows into the discharge chamber 80.
  • a cup 98 is mounted above the impeller 82 in fluid communication therewith through its lower opening 100, and the cup 98 carries a pair of upper ports 102 by which water passing through the upper portion 96 of the pressure chamber 94 may flow into the cup 98, and through which air may flow out of the cup 98 into the upper portion 96 of the pressure chamber 94.
  • the cup 98 defines an interior float chamber in which the float 104 of a float switch 106 is mounted.
  • the float 104 is mounted on a rotatable shaft 108 which extends through a water seal in a wall 112 of the pump housing assembly to a dry compartment in which electrical switch 106 is mounted.
  • the walls 112 form part of an upper cap casting 114 on which the electric motor is mounted by bolts 116.
  • the cap 114 is mounted on the lower casting 74 by means of bolts (not shown).
  • the float switch 106 is a switch which is normally open when water is not present in the cup 98 but which closes when the float 104 rises in the cup 98 rotating the shaft 108 responsive to introduction of water into the cup 98.
  • the switch 106 is connected to the electric motor to prevent operation of the electric motor until the switch 106 closes, and a manual start switch 118 (FIG. 1) is connected in series with the motor and switch 106.
  • Water so introduced into the vacuum hose flows through the intake chamber 78 and upwardly around the impeller 82 and through the pressure chamber 94 while air is displaced from the interior of the cup 98 through the apertures 102 and the upper portion 96 of the pressure chamber 94; when the water in the cup 98 rises to a sufiicient extent that the float switch 106 is closed, the impeller may then again operate.
  • a lateral conduit 120 is provided in the nozzle housing end of the hose 44 with the conduit 120 extending through the fitting 40 and having a lip 122 on its outer edge over which an auxiliary hose may be attached for connecting the vacuum hose 44 to the water faucet in a bathtub.
