Definitions

  • This invention relates to overflows from containers, such as baths, and, in particular, to devices for detecting such overflows and for shutting off the flow of water into the bath by turning off the supply of water automatically upon detection of an overflow.
  • an overflow device capable of being fitted to a container, such as a bath, said device comprising a vessel, inlet means arranged for the conduction of water into said vessel and outlet means arranged for the conduction of water out of said vessel, wherein the cross-sectional area of the inlet means is greater than the cross-sectional area of the outlet means.
  • said vessel is flexible so as to be capable of expanding in volume a ⁇ it is filled with water.
  • means for manually controlling the flow of water through said outlet means are provided.
  • plug means a manual mechanism adapted to control the opening and closing operations of said plug means and an alarm which is capable of providing a warning of overflow.
  • said outlet means include an opening in said vessel positioned above the level of water collecting in said vessel whereby air in said vessel can escape through said outlet means on entry of water through said inlet means.
  • said inlet means include an opening of small cross-sectional area for directing a small flow of water to said outlet means and an opening of larger cross- sectional area for directing a larger flow of water to said vessel.
  • Figures 1, 2 and 3 are diagrammatic sections through different overflow devices, all constructed, in accordance with the present invention, and, Figure 4 is a diagrammatic section through a water separation device.
  • the waste pipe system includes flexible members 20, 21 and, under the weight of water in vessel 14, these members 20,
  • levers 24, 25 connected through flexible linkages 26, 27 to a central lever 28. This in turn is connected through another flexible linkage 29 to vessel 14.
  • Levers 24, 25 have cranked portions 24a, 25a which operate on plungers 30, 31
  • the vessel 14 is a relatively inflexible unit but, as an
  • the vessel could be made flexible to expand with the introduction of water.
  • the waste 13 extends into the vessel 14 to form an upstand 13a in the vessel so that when a large overflow of water enters, the water will be retained in the vessel 14 and, if
  • Handle 35 can also be used to lower vessel 14 manually for testing for the overflow condition, to operate the valves to prevent sticking and to clear any scale from hole 22.
  • the water inlet pipe 12 and hole 22 form a differential flow system in which the maximum rate of flow into the vessel 14 (pipe 12) is greater than the maximum rate of flow out (hole 22) . This changes when vessel 14 is full as waste 13 then comes into use to carry away any excess of water.
  • Member 21 is in the form of an enlarged elbow which can flex to allow vessel 14 to move. Member 21 is connected to a further waste pipe 17.
  • the upstand 13a formed by waste pipe 13 extending into vessel 14 has a relatively large cross-sectional area. Thus, if a large quantity of overflow water enters vessel 14 when it is empty or nearly empty, air in the vessel will be expelled out of pipe 13 and will not be forced to try to bubble back through entry pipe 12. This precludes any resistance to overflow water flowing in along pipe 12.
  • the arrangement of Figure 2 is somewhat similar to that of Figure 1 in that the overflow from a bath (not shown) passes along inlet means in the form of a pipe 110, into a vessel 114.
  • the water in vessel 114 continues to drain out of hole 111 and if the overflow ceases, all the water will eventually drain out of vessel 114, thus releasing the lever system and allowing the valves 115, 116 to re-open and to re ⁇ establish the connection of water to pipes 118, 119 and thus to the taps (not shown) .
  • the waste pipe system comprises waste 113 connected through flexible member 121 to pipe 117.
  • Pipe 117 includes a manually operable valve 120 which is connected through a Bowden type cable 137 to a handle 135 of hexagonal cross- section. Handle 135 can be turned to close valve 120 in order to set the overflow system. With valve 120 closed, any water entering vessel 114 will collect there and should sufficient volume accumulate, the flow of water to the taps would be restricted. The system is reset by opening valve 120. This obviates the need for the differential flow aspect of the vessel 114 and setting / resetting is linked to movement of the bath plug (not shown) .
  • the lever mechanism operated by movement of vessel 114 under the weight of water when it is filled comprises levers 124, 125 connected through flexible linkages 126, 127 to the centre of vessel 114.
  • Levers 124, 125 have cranked portions 124a, 125a which operate on plungers 130, 131 directly to control valves 115, 116 and thus the flow of water to the taps (not shown) along pipes 118> 119.
  • Springs 132, 133 are adjustable to control the pressure at which the valves 115, 116 start to close.
  • overflow from a bath passes into a closed, stationary vessel 210. If a bather slops water about but the amount of overflow water is small, then it will pass through hole 211 in pipe 212 directly into waste pipe 217. If, however, the amount of the overflow is large, the bulk of the water passes into the vessel 210 because of the shape of pipe 212 and starts to fill vessel 210. This causes floats 213, 214 to float up and to shut off valves 216, 215 respectively, which are arranged to cut off flow to the taps (not shown) along pipes 224, 225.
  • the vessel 210 includes a small hole 218 and a needle member 219, which is positioned to close hole 218 when float 214 is raised by the rising level of overflow water.
  • Levers 220, 221 connect floats 213, 214 respectively to valves 216, 215 and these valves include valve shut-off pins 222, 223 and cranked lever parts 220a, 221a for closing valves 215, 216.
  • the waste 217 extends into the vessel 210 to form an upstand 217a in the vessel so that when a large overflow of water enters, the water will be retained in the vessel 210 and, if the overflow continues the excess of water will spill over upstand 217a and drain to waste.
  • the upstand 217a has a relatively large cross-sectional area. Thus, if a large quantity of overflow water enters vessel 210 when it is empty or nearly empty, air in the vessel will be expelled out of pipe 127 and will not be forced to try to bubble back through entry pipe 212.
  • Float 214 is connected by chain 229 to lever 230 so that when the float rises under rising water level needle 219 closes hole 218.
  • Handle 226 is connected through Bowden type cables 227, 228 to float 213 so as to be able to override the movement of float 213 under the effect of changing water levels, to raise and lower the float manually.
  • a similar handle and operating mechanism is provided for raising and lowering float 214 and this additionally causes needle 219 to be forced into hole 218 so as to keep the hole clear of scale.
  • the vessel 210 is watertight, except for the entry and exit pipes 212 and 217 respectively.
  • the raised part of the vessel containing valves 215, 216 is airtight so that rising water level will be prevented from contacting these valves.
  • FIG 4 there is shown an arrangement which can separate a large overflow condition from small amounts of water, which the bather can cause to slop over by normal movements. Such small amounts of water drain away through hole 312.
  • flow along pipe 310 will not all pass through hole 312 and the volume of water causes this pipe to fill up and flow over into pipe 311.
  • Water thus diverted along pipe 311 will pass to an overflow device such as that shown in any one of the earlier Figures, and will then pass back along pipe 313 to waste 314.
  • pipe 310 is connected to the incoming overflow and that pipe 314 is connected to the outgoing waste.
  • the hole 312 is formed in a separable member 315 which can be removed from the piping system for cleaning.

Abstract

Dispositif indicateur de débordement prévu pour une baignoire ou tout autre appareil similaire destiné à contenir de l'eau, utilisant un écoulement différentiel dans lequel la surface en coupe transversale de l'entrée est supérieure à celle de la sortie. Par conséquent l'eau pénétrant dans le dispositif s'accumule et la masse d'eau accumulée finit par provoquer une réaction dans le dispositif qui arrête l'alimentation en eau pour la baignoire. Ceci se produit si le volume d'eau est important, cependant, si une petite quantité d'eau déborde et pénètre dans le dispositif à cause des mouvements normaux de la personne se baignant, elle part dans l'écoulement des eaux usées (15, 16) sans pour autant provoquer l'arrêt des robinets (13).
