- the invention provides a deodorizing apparatus in which a [30] Foreign Apphcflion Priority Data flow of air generated by movement of water at some stage in a Aug. 1, i969 Great Britain ..38,652/69 flushing cycleof a urinal, water-closet basin or the like cornvenience is directed into a vessel capable of receiving a liquid [52] US. Cl ..4/226, 4/ 109; 4/222, and hence passes upwardly through the shorter leg of a 4/224 syphon tube and downwardly through the longer leg of the s 1 rm.
- the present invention relates to an apparatus for deodorizing the atmosphere and is primarily concerned with an apparatus whereby the. air in a particular locality is automatically given a charge of a volatile deodorant or disinfectant from time to time, for example, as with each flushing operation of a water supply cistern.
- a deodorizing apparatus in which air displaced by water from the flushing of a cistern is caused to pass through or by a pad soaked in deodorant liquid is known (see, for example, U.K. Pat. specification No.l,069,2l3). In such an apparatus, the air displaced picks up deodorant vapor from the pad and thenpasses into the atmosphere.
- pads have some disadvantages in that they have to, be changed periodically, they increase the initial cost of the apparatus, they can collect solid particles becoming contaminated and expensive deodorant liquid is wasted. It would, therefore, be advantageous to provide a deodorizing apparatus in which pads were not required.
- a deodorizing apparatus in which air is bubbled directly into deodorant liquid provides a more uniform dispersion of deodorant than is obtained in a deodorizing apparatus incorporating a pad.
- the former apparatus has a smaller surface area of deodorant liquid compared with the latter apparatus thus reducing losses by evaporation, and ensuring more effective use of deodorant liquid.
- a deodorizing apparatus can be provided which enables air displaced by water from a flushing cistern to be bubbled directly into deodorant liquid and atthe same time overcomes the above-mentioned problem of suck-back in a manner which is automatically effective and is very simple, requiring no valves or complicated devices.
- a deodorizing apparatus in which a flow of air generated by movement of water at some stage in a flushing cycle is directedinto a vessel capable of receiving a liquid and from thence passes upwardly through the shorter leg of a syphon duct, then downwardly through the longer leg of the syphon duct and then passes from the longer leg of the syphon duct into a deodorant liquid contained in a second vessel from which it emerges to deodorize the surrounding atmosphere, the end of the shorter leg of the syphon duct being near to the base of said first mentioned vessel and being above the lower end of the longer leg.
- a deodorizing apparatus of the present invention comprises a chamber into which flush water is allowed to rise to displace air therefrom either during the filling of a flushing cistern or during a flush therefrom, a first vessel capable of receiving a liquid, said vessel being in pneumatic communication with said chamber to receive air discharged therefrom, a second vessel for receiving a deodorant liquid, a syphon duct whose shorter leg extends upwardly from adjacent the base of said first vessel and whose longer leg extends downwardly towards the base of said second vessel, said vessels being pneumatically isolated from one another except for the connection afforded therebetween by said syphon tube.
- the deodorizing apparatusof the present invention may be used in conjunction with both high-flush" cisterns and lowflush cisterns.
- the chamber when used with a high-flush" cistern, the chamber may be connected to the flush pipe of the cistern so that water passing down the flush pipe enters the chamber to displace air therefrom.
- a "low-flush” cistern however, insufficient pressure is developed in the flush pipe during the flush.
- the chamber is therefore positioned in the cistern with an open end near the bottom of the cistern, the open end being above the minimum water level, so that when the cistern is being filled with water, air is displaced upwardly from the chamber.
- the deodorizing apparatus of the present invention comprises two chambers each with a vessel therein for receiving liquid, one of which chambers has an air discharge opening and the other chamber is connectable to a flushing system so as to give rise in known manner to an increase or pressure in said chamber at some stage of a flushing cycle and to a subsequent return to normal pressure therein, and a syphon duct whose shorter leg extends upwardly from adjacent the base of the vessel of said other chamber and whose longer leg extends downwardly towards the base of the vessel of said one chamber so that the lower end of the longer leg lies below the lower end'of the shorter leg, said chambers being pneumatically isolated except for .the connection therebetween afforded by said syphon duct.
- Deodorant liquid if sucked back through the syphon duct from the vessel in said one chamber to the vessel in said other chamber while the water drains from said other chamber, is subsequently syphoned back into the vessel in said one chamber.
- the preferred form of the deodorizing apparatus when used in conjunction with a high-flush" cistern, is provided with a float in said other chamber, said float being connected to a valve, positioned to control the flow of water into said other chamber.
- the float activates the valve so preventing further flow of water into said other chamber.
- said chambers can be incorporated in a single container with said air discharge opening in its upper part and with the syphon tube passing through a partition which seals one chamber from the other, passing below the vessel in said one chamber and above the vessel in said other chamber.
- said partition can comprise the vessel of said one chamber.
- deodorant liquids which can be used in the apparatus of the present invention are l. a mixture of isoeugenol, eugenol, geraniol and aromatic chemicals;
- liquids used in the apparatus of the present invention need not necessarily be restrictedto deodorant liquids.
- any volatile liquid, the vapor of which it is desired to disperse into the air could be used, for example, perfumes, insecticides, aromatics and the like. 7

- FIG. 2 is a section on the line AA ofFIG. 1;
- FIG. 3 is a section on the line 8-5 of FIG. 1;
- FIG. 4 is a front view of a low-flush arrangement
- FIG. .5 is a section on the line 8-8 of FIG. 4, a section on the line AA ofFlG. 4 being the sameas FIG. 2.
- the outer container 1 comprises a shell having a back-wall 2, a front-wall 3 and a base 9, and a grille 4 sealed to the back-wall 2 and front-wall 3.
- the grille 4 is secured in position by a screw 5 which engages in a threaded pillar 6 held by a second screw 7 to the inner face of the back-wall 2.
- A-pipe connection 10 is secured to the base 9 of the outer container 1.
- a pipe 11 of the pipe connection 10 leads to a flush pipe.
- the pipe connection 10' includes a valve housing 12.
- a valve 15 in the valve housing 12 has a valve stem 16 connected at its upper end to a float 17, comprising a sealed hollow container which may be of metal or plastics material.
- the outer container 1 has two chambers 23 and 24 which are separated by an internal diaphragm 18, which is held in position by the screw 5 and sealed by an epoxy resin gasket (not shown).
- the diaphragm 18 is conveniently constructed from an acetal copolymer such as Kematal.”
- Each chamber 23 and 24 is provided with a vessel 19 and 22 for receiving liquid.
- the second vessel 19 is actually part of the diaphragm 18 and the first vessel 22 is firmly affixed to the back-wall 2 of the outer container 1.
- the other chamber 24 is connectable to a flushing system via the valve housing 12, the pipe connection 10 and the pipe 11.
- a syphon duct in the form of a copper U-tube 20 passes through the diaphragm l8 and is held in position by means of a neoprene grommet 21.
- the shorter leg of the U-tube 20 extends upwardly from adjacent the base of the first vessel 22 of the chamber 24 and the longer leg 26 of the U-tube 20 extends downwardly towards the base of the second vessel l9'of the chamber 23.
- the lower end of the longer leg 26 lies below the lower end of'the shorter leg 25.
- the chambers 23 and 24 are pneumatically isolated from one another except for the connection therebetween afforded by the U-tube 20.
- a flush of water passes down the flush pipe to which the pipe 11 is connected. Water enters the chamber 24 and rises therein.
- the float l7 and the valve 15 are arranged to restrict the rise of water in the chamber 24.
- the movement of water causes a flow of air tobe generated.
- the air passes into the first vessel 22, upwardly through the shorter leg 25 of the U-tube 20, downwardly through the longer leg 26 of the U- tube 20 into deodorant liquid contained in thesecond vessel 19. The air thus picks up deodorant and passes through the grille 4 into the atmosphere.
- FIGS.4 and 5 certain parts are identical with those in FIGS. 1, 2 and 3 and these have been given the same reference numerals. Moreover the section according to FIG.2 also applies to the embodiment of FIGS.4 and 5.
- FIGS.4 and 5 differs from that of FIGSJ to 3 in that the valve 15 and the float 17 are omitted and in place of thepipe 11, a pipe 27 is secured to the base 9 of the outer container. This pipe 27 leads to a container 28 to which'it is connected. The container 28 is open-bottomed and is positioned within a cistern 29.
- a disinfecting device can be provided in the chamber 24.
- Such ,disinfectingdevice can comprise an inverted inner container within the chamber 24 with its lower end spaced above the base 9 and closed by a layer, wad or plug of reticulate or foraminous material as described more fully in the above-mentioned British Pat. specification No. 1,069,213.
- a viscous, slowly mobile disinfectant composition inside the inverted container rests on the upper face of the layer, wad or plug.
- the chamber 24 does not drain completely at the end of the flush and some disinfectant composition diffuses through the layer, wad or plug during the interval between flushes to form with the residual liquid retained in the bottom of the container 24 a concentrated disinfectant solution.
- This concentrated solution is diluted by flushing water fed through the pipe 11 during a flush and the diluted disinfectant solution discharges itself from the container 1 into the convenience at the end of a flush.
- a disinfecting device can be attached to the open-bottomed container 28 disposed in the cistern 29.
- such disinfecting device can comprise an inverted inner container disposed within a separate outer container in its lower end closed by a layer, wad or plug as described more fully in British Pat. specification No.l,070,l88.
