United States Patent REMOVAL OF ODOURS FROM TOILETS AND CLEANSING 0F SAME Bela Balsay, 87 Crystal St., Petersham, near Sydney, New South Wales, Australia Filed Feb. 20, 1967, Ser. No. 617,281 Claims priority, application Australia, Feb. 22, 1966, 1,951/ 66 Int. Cl. E03d 9/04, 9/02 US. Cl. 4213 Claims ABSTRACT OF THE DISCLOSURE This invention relates to means for the removal of unpleasant odours from the toilet bowls of toilet pedestals and the like, and also the cleansing of such toilet bowls and the disinfecting and deodorizing of the area thereabout.

The invention has been devised to provide means of a reliable, safe and simple nature whereby toilet odours are removed from a toilet bowl before they can become objectionable within a room or other location of the related toilet, thereby affording a very desirable service within homes as well as other places of use. The invention also provides for the automatic dispensing of a detergent or the like to the toilet bowl with the flushing water at each time a flush of the toilet is effected.

The invention can be readily embodied in toilet pedestals or at a location where the water passes in a flushing operation as hereinafter described.

According to this invention, the means for the removal of unpleasant odours from the toilet bowls of toilet pedestals and the like and the cleansing of such bowls, are characterised by a hollow air removal member containing a compartment arranged across the back of the top of the pedestal or the like and connected by at least one air draw-off passage or port with the usual water flushing channel of the toilet bowl above the location where the flow of flushing water is effected and also connected to a ventilating housing integrally formed in or on said pedestal and containing an air-draw-off or suction device; and a dispenser for automatically dispensing detergent or the like for effecting the cleansing, disinfecting and deodorising of said toilet bowl built into or arranged with said toilet pedestal in such a manner that the flushing water in its flow path to the toilet bowl receives a charge of detergent or the like so that it is mixed with and absorbed into the said flushing water and delivered therewith to the said toilet bowl at each flushing operation.

The ventilating housing is positioned at a convenient location in the toilet pedestal such as at the back thereof above the discharge bend or the like of a toilet pedestal.

The air suction device contained within the ventilation housing may be of any suitable form, as for example an electric motor driven impellor or fan type of device, and the operation thereof may be manually effected or done automatically by any means devised for the purpose.

The detergent dispenser in some applications of the invention is embodied in the toilet pedestal and connected ice by one or more ports or the like leading to the toilet bowl as under the usual int-urned depending lip or hanging provided at the top of the said bowl, and so arranged that some of the water at a flushing operation is directed through the dispenser before passing to the toilet bowl, and in such passage absorbing a suitable charge of the detergent which is distributed over the area of said toilet bowl.

In another application, the dispenser is embodied in the water flush supply line and connected therewith by port or like means so that a portion of the flushing water passes through said dispenser and absorbs a suitable amount of the detergent for the flushing operation.

In a still further application, the dispenser is embodied in a flushing cistern or the like, or in the water outlet line therefrom so that as a 'water flush takes place a supply of detergent is absorbed in the flushing water.

However, it is to be understood that the detergent dispenser is not limited to any precise location when built in or on a toilet assembly or suite and can be embodied at any suitable position so that the detergent is in contact with the flushing water only during a flushing operation.

In this complete specification, the use of the term detergent is intended to include any suitable cleansing agent or preparation whether or not it embodies a distinfecting and/or deodorising medium. Such detergent may be of powdered, granulated, crystal, block, stick or other suitable form for its purpose, and in some cases may be embodied in a perforated or mesh cage, frame or other container whereby it can be gradually absorbed into the flushing water. Gradual absorption in suflicient amount is most economical but the amount supplied is not intended to be limited in any way in present invention.

In order to describe the invention more fully, reference will now be made to the accompanying drawings, wherein:

FIGURE 1 is a rear end elevation of a toilet pedestal assembly in which the invention is embodied, and

FIGURE 2 is a side elevation of same, while FIGURE 3 is a plan thereof, and

FIGURE 3A a fragmentary plan of the toilet pedestal showing a varied position for the detergent dispenser.

FIGURE 4 is a fragmentary sectional elevation of the pedestal on line 4-4 of FIGURE 1.

FIGURE 5 is a sectional plan on line 55 of FIGURE 1, and

FIGURE 6 is a fragmentary section of the toilet bowl on line 66 of FIGURE 5 to show the construction of the dispenser more clearly.

FIGURE 7 is a side view of a combined closure plug and detergent block embodied in a mesh framing or the like as applicable for cisterns as shown in further figures of the drawings later detailed.

FIGURE 8 is a side view of a toilet suite including a modification of the application of the detergent dispenser shown in section.

FIGURE 9 is a sectional view of part of the lower portion of a cistern with the detergent dispenser arranged in the flush water outlet.

Referring to FIGURES l to 5 inclusive of the drawings, the toilet pedestal generally indicated by the reference 10 follows the usual form of such an article and includes a footing 11 to seat on a supporting surface, a discharge or outlet bend 12 and a flat top rim portion 13 upon which a seat (not shown) is adapted to be mounted in any suitable known manner. This top portion 13 has an internal downturned or depending flange 14 of more or less usual form providing the flush channel 15 through which a flush takes place in normal manner as from a water inlet 16 connected to a cistern (not shown) in usual manner. This water inlet 16 is connected by two ports 17 with the flush channel 15 see FIGURES 1, 4 and 5.

The pedestal 10 has at the back above the discharge bend 12 a circular built-in ventilation housing 19 in which a suction device 20 is fitted and may be of any suitable electrically operated fan form and is adapted to draw or suck the polluted air from the interior of the toilet bowl of pedestal 10, through an intake or draw-off pipe 21 connected to an intake port 22 (see FIGURE 1) arranged towards one end of an upstanding integral air removal member 23 extending across the back of the pedestal 10. This air removal member 23 encloses a compartment 24 connecting at its underside with a. draw-off passage 25 (see FIGURE 4) arranged above the water inlet 16 and communicating with the flush'channel 15, so that polluted air can be drawn-off from the bowl-of the pedestal 10 through the draw-oft passage 25, and discharged via compartment 24, pipe 21 and suction device 20 through a filter 26 (see FIGURES l and 2) of any suitable form, as for example one of carbon type to purify the air discharge.

The aforesaid suction device '20 may beactuated manually as by switch or other means and in some cases may be operated automatically in any suitable manner, as for example, from the toilet seat of an assembly.

Now referring to the detergent dispenser generally indicated by reference 27 (this is shown in FIGURES 1, 2, 3, and 6) contains a compartment 28 and is formed intogral with the pedestal at one side of the rear and is of a size to contain a suitable quantity of detergent, and has an orifice 29 (see FIGURE 3) through which the detergent is supplied, and is adapted to receive a removable closure plug of any suitable form. Said detergent dispenser 27 has flush water ports 30 shown in FIGURES 5 and 6, leading thereto from the flush channel so that some of the flush water enters the dispenser compartment 28 and makes its exit through lower ports 31 leading out from said compartment 28 through the wall of the pedestal bowl and is adapted to carry a charge of the detergent into said bowl which being absorbed in the flushing water effects the cleansing of the toilet bowl and may act also to disinfect and deodorise same according to the type of detergent used.

In FIGURE 7 the detergent includes a plug 32 having a detergent block or stick 33 moulded thereto, such block preferably being arranged in a perforated frame or casing which may be of any suitable material, say a plastic, and said block is slowly dissolvable as the flush water passes therebout and can be arranged to last an appreciable time before needing to be replaced.

Referring to FIGURE 3A the detergent dispenser is arranged under the rim 13 in the flushing channel 15 and includes an orifice 29 through which a detergent plug 32-33 may be fitted. This plug depending in the fiush channel 15 may itself constitute the detergent dispenser, as portion of the flush water circulates thereabout during a flushing operation.

In use when a flush takes place the flushing water passes through the water inlet 16, and through ports 17 into flush channel 15 and so to the toilet bowl, and the flow of the water creates a pressure effect in its passage, and as part of the fiushwater passes through the detergent compartment 28 the pressure effect assures that a suitable charge of detergent is dissolved and absorbed in the passing water.

By the operation of the suction device 20, the polluted air from the toilet bowl is drawn into the channel 15 and passes above the ports 17 and thence by draw-oft passage 25 through elevated compartment 24 of air removal member 23 and by intake pipe 21 is drawn through suction device to discharge to the filter 26. The suction device 20 can be shut-oif after a suitable interval of operation by any known means of control as before mentioned. Due to the elevation of the air removal member 23 and the connection therto of the pipe 21 and the disposition of draw-off passage there is no possibility of water entering the suction line.

Referring to FIGURE 8, the p l 0 as a fl s supply pipe 35 connecting to a cistern 36 and the detergent dispenser 27 is provided at one side adjacent the pipe bend and has a filling plug 37 in a top orifice and the compartment 28 is shown containing a block or stick 33 of detergent. Water inlet and outlet ports 38 are arranged in the upper and lower parts of the dispenser compartment 28 so that a portionof the flush water passes therethrough and absorbs a desirable amount of the detergent which passes into the main flush flowing through the pipe 35 to the bowl of the pedestal 10.

' Referring to FIGURE 9 the cistern 36 has a flush valve 39 therein of usual form seating over an outlet orifice 40, under which is a detergent dispenser 27 formed as a compartment 28 interposed between the cistern outlet and the flush pipe 35. A detergent plug 32. as before described with reference to FIGURE 7 is fitted through an orifice in one side of the detergent dispenser 27 and'can be renewed as required.

The detergent in some cases may include a foaming agent or a colouring dye or the like to tint the flushing water and provide an indication that the dispenser is working. In this case when the flush water is not forming foam or is untinted an indication is given for the renewal of the detergent.

It is to be understood that while several methods of embodying a detergent dispenser have been described and illustrated, the invention is not limited to the precise applications shown as such dispenser may be arranged in other ways tovperform the required function, all such ways coming withinthe scope of present invention, that is to say the detergent is in contact with the flushing water only during a flushing operation, and such dispenser is formed as an integral part of the toilet bowl of a pedestal, flush pipe or cistern and the position of said dispenser is always in the path of the flushing water.
