Auxiliary water receptacle apparatus

Abstract

For combination with a flush toilet water tank having a side wall, a pond water receptacle integrated with said tank side wall at the exterior of the tank, the receptacle opening upwardly, there being a water passage through the tank side wall, whereby pond water in the receptacle has a gravity determined top level at approximately the same level as water in the tank, and a removable cover extending over water in the receptacle, protecting against contaminated pond water gaining access to tank water.

Claims

1. A flush toilet water tank combined with a pond water receptacle, wherein: (a) the pond water receptacle (i) includes an upwardly oriented opening and (ii) is integrated with a side wall of said flush toilet water tank so that the pond water receptacle is located on the exterior of the flush toilet water tank; (b) a passage is provided through said side wall of said flush toilet water tank and the passage includes a primary valve that may be opened to provide fluid communication via said passage between said flush toilet water tank and said pond water receptacle and that may be closed to shut-off said fluid communication between the flush toilet water tank and the pond water receptacle whereby pond water in the pond water receptacle has a gravity determined top level that settles with the surface level of water in the flush toilet water tank whenever the primary valve is opened and whereby pond water in the pond water receptacle has a gravity determined top level that does not settle with the surface level of the water in the flush toilet tank whenever the primary valve is closed; (c) a removable cover extends over the upwardly oriented opening of the pond water receptacle to protect the pond water in the pond water receptacle against contamination entering the pond water receptacle through the upwardly oriented opening; (d) a drain with a secondary valve is provided in a bottom wall of the pond water receptacle so that the secondary valve of the drain may be opened when said primary valve is closed to discharge water in the pond water receptacle through said drain so that the top level of the pond water is lowered without the surface level of water in the flush toilet settling with the top level of pond water, (e) the pond water in the pond water receptacle is isolated from water in the main tank whenever the primary valve is closed so that the pond water receptacle may be cleaned without fluid communication between the pond water receptacle and the flush toilet water tank.

2. The flush toilet water tank combined with a pond water receptacle of claim 1 wherein after the primary valve is closed, the secondary valve opened, and the pond water drained from the pond water receptacle so that said gravity determined top level is lowered, said secondary valve may be closed and said primary valve be opened to cause the surface level of water in the flush toilet to settle with the top level of the pond water.

Description

DRAWING DESCRIPTION

(1) FIGS. 1 and 2 are side and end elevations of a toilet, toilet tank, and smaller pond receptacle;

(2) FIGS. 3 and 4 are like FIGS. 1 and 2, but are sectioned to show internal constructions;

(3) FIG. 5 is a top plan view;

(4) FIG. 6 is a top view and a modification; and FIG. 6a is like FIG. 6, but showing structure modified positioning;

(5) FIGS. 7a-7e are fragmentary views of modes of operation.

DETAILED DESCRIPTION

(6) In FIGS. 1-4, a toilet or water tank installation 10 is shown. An auxiliary pond water receptacle, or cistern 12 is also shown, installed on a side wall 13 of tank 11. A through opening 14 between the interiors of 11 and 12 is provided, whereby flushing water 15 in tank 11 gains access to and supplies water 16 to the interior of the cistern. Water levels 18 and 19 in 11 and 12 are therefore the same, as indicated by surface level line 20. The top edge level of 12 appears at 12a, higher than water level line 20. When a hand-operated flush lever 21 is rotated, water leaves tank 11 and cistern 12 to flush the toilet 23.

(7) As seen at 26 in FIG. 3, a removable lid 30 is seated on upper rim 31 of the cistern 12. It may be rotated between closed and open positions, about a vertical axis 33 by provision of a lid carried dowel 31 received in opening 32 on the cistern wall. See FIG. 6. Dowel axis 33 is also seen.

(8) A secondary valve 51 in the bottom wall 34 of the cistern is provided to discharge water such as contaminated water from the cistern, as when a primary valve 50 is closed, to close downward opening 53, after cleaning of cistern as by brush 36 seen in FIG. 7c. Thereafter, valve 51 is closed, and the cistern re-fills after opening of valve 50 that controls communication between the water in tank 11 and water in the receptacle 12. See schematic FIG. 7a-7e views.

(9) In the FIG. 7a-7e views, a step-by-step cleaning of the pond receptacle is shown.

(10) In FIG. 7a, primary valve 50 is open and secondary valve 51 is closed. Valve 50 controls an opening 52 between tank 11 and cistern 12; and valve 51 controls a discharge opening 53 from cistern to the exterior.

(11) In FIG. 7b, valve 50 is closed and valve 51 is open. This allows discharge of cistern water without discharging contents of 11. Water level in the cistern may be dropped prior to cleaning.

(12) In FIG. 7c, both valves 50 and 51 are closed, and a brush 64 is inserted into 12 and the brush is moved about, for cleaning of walls of the cistern.

(13) In FIG. 7d, both valves are open to effect discharge of contaminated water, and flushing of the cistern by water from the tank 11.

(14) In FIG. 7e, valve 50 is open and valve 51 closed, to allow re-fill of the cistern with clean water from the tank. This reestablishes the common surface level of water in tank 11 and the cistern.
