Problems solved by technology

A common problem with waste water drain pipes is that odours can be emitted from them that offend most people's olfactory senses.
This is mainly due to debris, such as food, hair and/or detergent, passing into the waste water drain pipe, decomposing and creating putrid water.
A difficulty with the S-bend is it is generally located a long way from the floor waste.
Therefore, debris can become stuck within the drain pipe between the floor waste and S-bend to create an unpleasant od

Embodiment Construction

[0031]FIGS. 1 to 7 show a drain fitting 10 for use in a shower waste 11 to assist in preventing odours from passing out of the shower waste 11. A typical shower waste 11 includes a grate 12 and a waste body 13 as shown in FIG. 7. The grate 12 normally fits within the waste body 13 using a bayonet type attachment.

[0032]The drain fitting 10 includes a conduit 20, a base cap 30 and a cage 40. The conduit 20, base cap 30 and cage 40 are all made from plastic. However, it should be appreciated that the conduit 20, base cap 30 and cage 40 may be made from other materials such a metal.

[0033]The conduit 20 is used to increase the velocity of water 50 that flows through the conduit 20. The conduit 20 is in the form of funnel that has an upper portion 21 and a lower portion 22. The upper portion 21 of the conduit 20 has an internal wall 23 that is inclined at an angle of approximately 60 degrees. The lower portion 24 of the conduit 20 has an internal wall 24 that is inclined at approximately ...

Abstract

A drain fitting comprising a cage having a plurality of apertures extending through the cage; a conduit having an inlet and an outlet, the conduit extending at least partially through the cage; and a base cap attached to the cage, the outlet located within the base cap wherein the conduit includes an internal surface that extends from the inlet to the outlet, the internal surface increasing the velocity of the water substantially the length of the internal surface as the water passes from the inlet to the outlet.

Description

FIELD OF THE INVENTION[0001]This invention relates to a drain fitting. In particular, the invention relates to a drain fitting for use in floor and shower wastes for both commercial and domestic applications and will be described in this context. However, it should be appreciated that the drain fitting may be used for other applications.BACKGROUND OF THE INVENTION[0002]Waste water drain pipes have been around for thousands of years and still play an important part in most buildings throughout the world. A common problem with waste water drain pipes is that odours can be emitted from them that offend most people's olfactory senses. This is mainly due to debris, such as food, hair and / or detergent, passing into the waste water drain pipe, decomposing and creating putrid water.[0003]A reasonably effective way in which to overcome offensive smells that are emitted from waste water drain pipes is to install an S-bend. An S-bend provides a water seal in the pipe to prevent odours from pas...
