Definitions

  • This invention relates to a whirlpool system wherein air is blown into the water through an air pump.
  • the dosing of the air in the water is effected by an insufflation nipple, generally known as a jet. Consequently, they will be referred to as jets herein.
  • the existing jets can dose the air in the water through one or more exhaust outlets, with the air being exhausted either straightly upwards or laterally.
  • the jets are provided mostly in the bottoms of baths, it will be clear that the effect of the jets blowing straightly upwards is strongly reduced or entirely impeded when a bathing person places himself on it. It has been tried to remove this problem by blowing out the air laterally, which precludes purposive exhaust of air in upward direction.
  • the upwardly directed air jets are used for jetting the known massage points in the back or other parts of the body.
  • insufflation systems are used wherein the air is not preheated, in which case the contemplated effect, relaxation of the muscles, will precisely be reversed, as the muscles warmed up already by the hot bath water will precisely be strained by the cold air.
  • a whirlpool system comprising an air insufflation system with insufflation jets and an air pump is characterized in that the insufflation jets have a flat, disc-shaped head with a plurality of radial air outlets and at least one air outlet extending substantially transversely to the plane of the disc-­shaped head
  • Fig. 1 and Fig.2 are a diagrammatic top view, and a side view, respectively, of an example of a bath tub 1 having a whirlpool system.
  • air insufflation means the so-called jets, indicated at 4.
  • the jets Through the jets, air can be insufflated into the water-filled bath, as diagrammatically shown at 5.
  • the air to be insufflated is preferably heated to above the body temperature by means, not shown, comprising e.g. an electric heating element, whether or not combined with the air pump.
  • Figs. 3-5 diagrammatically show an embodiment of a jet for a whirlpool system according to the present invention.
  • the jet is designed in such a manner that there is no exclusively upward or exclusively lateral exhaust, but both an upward and a lateral exhaust, so that both an accurately defined local effect and a more spatially distributed effect occur.
  • the jet shown includes a head 10, which is very flat, having a beveled edge 11, so that the jet can be placed conveniently in the bottom of a bath tub.
  • jet 10 is substantially disc-shaped with a central axial outlet 12 and a plurality of radial outlets 13.
  • the disc-shaped head is provided at the underside with a central tubular portion 14, which is threaded externally.
  • the tubular portion forms an air chamber that communicates directly with the outlet 12 and through radial channels 15 with the outlets 13.
  • the threaded tubular portion in mounted condition, is screwed into a tubular jet body 16 having a flat upper flange 17 which, through a sealing ring 17a, lies on the bottom of the bath tub.
  • the jet body 16 is furthermore provided with external screw thread 18 spaced apart from flange 17, and can be secured with a nut 19.
  • the threaded portion 14 of the head is screwed in an enlarged chamber 20 in the jet body.
  • the enlarged chamber 20 connects to a narrower axial air supply channel 21, which can be supplied with air through e.g. a flexible hose 22.
  • Hose 22 can be mounted on a narrowed portion 23 of the jet body e.g. with a hose clamp.
  • the chamber 20 contains a ball 24, made e.g. from stainless steel, and which, in the rest position, closes air supply channel 21 under the influence of pressure exerted by a spring 25.
  • Spring 25 has its end remote from ball 24 bearing on a valve member 26 extending axially within chamber 20 into the tubular portion 14 of the head.
  • the valve member has an upper, e.g. cylindrical, portion 27, extending above a peripheral shoulder 28, and loosely fitting in the tubular portion 14. Resting on the peripheral shoulder is a spring 29 placed around portion 27, which spring bears at its other end on the upper wall of the air chamber in the head. Spring 29, consequently, presses valve member 26 downwards.
  • sealing ring 30 e.g.an O-ring, adapted to sealingly coact with a recessed edge 31 formed in chamber 20.
  • the sealing ring lies in a recess 32 in the valve member.
  • Fig. 6 is a diagrammatic side view of a bath tub 1 filled up to the maximum level 40 defined conventionally by an overflow.
  • the bath tub is provided with jets, not shown in Fig.6, which can be provided with air through an air supply system.
  • the air supply system includes an electric pump 41, which may have a heating element, and which can supply air to the jets through a pipe 42.
  • Pipe 42 in this example, includes a substantially horizontal portion 43, sometimes called "air buffer", and which is connected to the jets again through branch pipes and flexible hoses.
  • the pipe further includes an inverted-U-shaped portion 44 whose horizontal path 45 lies above the maximum level 40. Even if both seals of a jet are inoperative, water can still not reach the electric pump. At any rate, the U-shaped portion is preferably made from hard tube secured to the pump, so that a vertical position is maintained.
  • a non-return valve 46 can be provided in the horizontal path 45 for the sake of security.
  • the air output may for instance be controllable.
  • the air pump can continue blowing for a while after bathing, so that the bath can be after-­dried.
  • a germ-removing or germ-­destroying installation can be incorporated in the system.
  • the system described can be used in any bath of any design, material and model, also in a shower cubicle or shower bath as a foot massaging device.
  • the system can be employed for any purpose contemplated by the user.
  • the system can be utilized in any other environment, unit, combination etc. contemplated by the user.
