Abstract

A trap for a sink or other drain incorporates a holder 8 for solid disinfectant 9 interposed between the trap water and an inlet grating 11. The trap of Fig. 1 comprises a cup 1 having a bottom flange 12 for connection to a drain, and an upstanding outlet pipe 2 which has radial flanges supporting an overlying cover 6 and disinfectant holder 8. In a modification the outlet pipe is of semi- circular cross-section. Fig. 3 illustrates an alternative trap having an inner cup 14, of dip tube 16, and a disinfectant holder 8. <IMAGE>

Description

SPECIFICATION Outlet Fitting for Water Drainage System This invention relates to improvements in the outlet fitting for a water drainage system of the kind employed, for example, with sinks, baths, drains and the like. In previous outlet fittings it has been possible for pests and unpleasant odours to enter a-building through the water drainage system and therefore would be both detrimental to health and to environmental cleanliness.
Hereinbelow we describe several preferred embodiments of an outlet fitting, in accordance with the present invention, for receipt of waste water, each of which fittings is adapted for connection to a drainage pipe and consists of: a filter through which waste water may pass; a cup shaped member, arranged to be coupled to a drainage pipe which member is arranged to receive said waste water and includes means adapted to provide a water trap in use; and upstream of said water trap a holder for solid deodorant, disinfectant and the like.
The water trap and the holder may together define in effect an S-shaped weir through which the waste water must pass before entering the drainage system. Direct access between the drainage pipe and the filter is prevented. Any pests entering the cup shaped member from the drainage pipe must first pass through the water trap where they tend to drown. The holder is provided with solid disinfectant, deodoriser or the like to eliminate any unpleasant odours emanating from the drainage system.
The invention is hereinafter more particularly described, by way of example only, with respect to the accompanying drawings in which: Figure 1 is a sectional view of a first ambodiment of the invention; Figure 2 is a sectional view taken along the line A--4 in Figure 1; Figure 3 is a sectional view, taken along the line C-C in Figure 4, of a second embodiment of the invention; Figure 4 is a sectional view taken along the line B-B in Figure 3; Figure 5 is a sectional view of a third embodiment of the invention; and Figure 6 is a sectional view taken along the line D-D in Figure 5.
In Figure 1, there is shown a cup shaped member 1 which is connected to a pipe 17 by means of a flange 12. A tubular member 2 extends from the bottom of the cup shaped member 1 into its interior, defining an outlet passage 3. Connected to the tubular member 2 are three support ribs 4 having shoulders 5 on which is placed a cover 6, which incorporates a holder 8 for deodoriser 9 or the like. A filter 11 is held in position above the cup shaped member 1 by means of a flange over 10.
In use water flows through the outlet fitting in the direction shown by the arrows in Figure 1, over the cover 6 and into the bottom of the cup shaped member. The drainage water can flow from the water trap up through the three spaces 7 defined between the support ribs 4, tubular member 2 and cover 6, and thence through outlet passage 3 and down the drainage pipe 1 7.
The embodiment of Figure 3 employs a cup shaped member 13 shown connected to a pipe 17. A second cup shaped member 14 is mounted within the first and above the bottom thereof by means of projecting portion 1 5 (Figure 4).
Inserted into the member 14 is a funnel 16 which is integral with the flange cover 10. The funnel 1 6 rests on an shoulder 21 in the number 14. The flange cover 10 holds filter 11 in position above the funnel. Directly below and connected to the filter 11 is a plate 23 which contains holes 20 through which water can flow. The plate 23 also contains holder 8 for deodoriser 9 or the like.
Waste water will flow down through funnel 1 6, through the water trap defined by member 14, and then down the drainage pipe 1 7 in a continuous manner as shown by the arrows.
Figures 5 and 6 show a further embodiment comprising a cup shaped member 1 connected to pipe 1 7 by means of a flange 12. Extending into the interior of the cup shaped member from its bottom is a semi-circular tubular member 24 at the top of which is a semi-circular opening 18 over the top of which waste water may pass from the water trap provided in the bottom of cup shaped member 1. A cover 6 is held in place above the tubular member 24 by means of a shoulder 22 on that member. As before the cover 6 incorporates a holder 8 for deodoriser 9 or the like. In operation waste water flows through filter 11 and into the water trap, thence up through semi-circular space 1 9 (Figure 6) and into tubular member 24, all as shown by the arrows in Figure 5.
Claims
1. An outlet fitting for a water drainage system, adapted for connection to a drainage pipe, and consisting of: a filter through which waste water may pass; a cup shaped member, arranged to be coupled to a drainage pipe which member is arranged to receive waste water which has passed the filter and includes means adapted to provide a water trap in use; and upstream of said water trap a holder for solid deodorant or disinfectant.
2. An outlet fitting according to Claim 1, wherein the water trap and the holder in section effectively define an S-shaped weir through which said waste water must pass before entering the drainage pipe, thus preventing direct access between the drainage pipe and the filter.
