Abstract

In order to extract air from a toilet pan 12 a wall-mounted extractor fan 15 discharging to the external atmosphere is coupled by a hose B either (a) to an aperture 10 formed in the flush pipe 11 or (b) to an inverted-U nozzle hooked over the rim of the pan without obstructing the closing of the lid. In a modification the directly-discharging fan 15 is replaced by a fan in a closed wall-mounted housing provided with inlet and outlet hoses. <IMAGE>

Description

SPECIFICATION Improvements in or relating to toilets This invention relates to toilets and its principal object is to provide a system wherein vapours are removed from the toilet pan and vented to the outside so that they are prevented from entering the room in which the toilet is situated.

According to the invention, means are provided for applying suction to the interior of the toilet pan and for conveying the vapours thereby removed from the pan to the external atmosphere.

According to one embodiment, an aperture is formed in the flush pipe and means are provided for applying suction to said aperture and for conveying vapours removed via said apertureto the external atmosphere either directly or indirectly. Said aperture may advantageously be located immediately above .: ie toilet pan and suction applied to the pan by means of an extractor fan located on an outside wall, the fan being connected to the aperture by means of a flexible hose.

Means may be provided to renderthe extractor fan located on an outside wall, the fan being connected to the aperture by means of a flexible hose.

Means may be provided to renderthe extractor fan inoperative when the flush pipe is in use.

According to another embodiment, which avoids the necessity of making an aperture in the flush pipe, suction is applied to the interior of the pan by means of a nozzle which is so shaped that it may be fitted over the rim of the pan without obstructing the closing of the lid, said nozzle being connected to an extractorfan by means of a flexible hose.

According to afurtherfeature ofthe invention,the extractor fan may be located within a housing which may be attached to a wall of the toilet room, said housing being adapted to be connected at one end to a hose conveying vapours from the interiorofthe pan and at the other end to a hose for conveying said vapours to the external atmosphere.

The invention will now be described with reference to the accompanying drawings, wherein: Figure 1 illustrates one embodiment, and Figures 2 and 3 illustrate another embodiment.

Referring first to Figure 1, an aperture lOis formed in the flush pipe 11 a short distance above the toilet pan 12 and aflexible hose 13 is connected atone end over said aperture by means of a suitable clamping device 14 and at the other end to an extractor fan 15 located on an outside wall.

Referring now to Figure 2, a nozzle 16forfitting over the rim of the toilet pan is of substantially U-shape comprising an arm 17 for location within the pan, an arm 18 for con nection to an evacuating hose 1 9, and a flat piece 20 connecting said arms, so that the lid of the pan can rest on said flap piece 20. Vapours from the pan are evacuated via the nozzle and passed to the external atmosphere via the hose 19.

Referring nowto Figure 3, an extractorfan (not shown) for applying suction to the interiorofthe pan is located within a housing 21 which is formed with an aperture at one end for the connection of a hose 22 connected to the pan and with an aperture at the other end forthe connection of a hose 23 for passing the vapours to the external atmosphere for example via the waste pipe. 24 indicates the electrical connection to the extractorfan. The housing 21 is provided with brackets 25 by means of which it may be attached to a suitable supporting surface.

The device according to the invention can be fitted easily and can be adapted for use in any location by adjustment ofthe length of the flexible hose or hoses.

1. Atoiletwherein means are provided for applying suction to the interior ofthe toilet pan and for conveying vapoursthereby removed from the pan to the external atmosphere.
