Odourless toilet

Abstract

During use of a traditional toilet off odours and air borne bacteria may enter the immediate atmosphere. A toilet (10) is provided comprising a flush tank (11) including a wet chamber (13), which comprises a flush assembly (15) and a flush outlet (17). The toilet (10) further comprises a ventilator inlet (21) and a ventilator (23). The toilet (10) also optionally comprises a toilet bowl (25), which comprises a basin (27) and a basin access (29). In one aspect, the toilet (10) comprises a diverter (35) positioned between the flush tank (11) and the toilet bowl (25) registering with the basin access (29). The diverter (35) comprises a flush passage (37), which couples the flush outlet (17) to a wet inlet (31) of the basin access (29). The diverter (35) also comprises an exhaust passage (39), which couples the ventilator inlet (21) to a dry outlet (33) of the basin access (29). In another aspect, the flush assembly (15) comprises a flush ventilation assembly (28), which comprises an overflow tube (18) and an overflow flush valve (20). The flush ventilation assembly (28) permits basin air to be drawn to the ventilator (23) through the overflow tube (18).

Description

FIELD OF THE INVENTION[0001]The present invention relates to odourless toilets.BACKGROUND OF THE INVENTION[0002]During toilet use, off odours and air borne bacteria may enter the immediate atmosphere. The odours and bacteria are generally considered undesirable. Several toilet designs have been proposed to deal with this problem; e.g., U.S. Pat. Nos. 5,257,421, 6,526,598 and 6,928,666. Each, however, poses a number of problems, such as, the toilet design being too complex and expensive to manufacture (cost prohibitive), or having a large number of moving parts (maintenance prohibitive), or requiring excessive reconfiguration of an existing toilet facility.[0003]There remains a need for an odourless toilet that mitigates or obviates at least some of these problems.SUMMARY[0004]An odourless toilet having a design that permits direct interchangeability with standard toilet fitting specifications is provided. The toilet venting, the vacuum and exhaust, is preferably integrated within th...

AI Technical Summary

Benefits of technology

"The patent describes an odourless toilet that has a design that allows for direct interchangeability with standard toilet fittings. The toilet has a flush tank, a wet chamber, and a dry chamber. The dry chamber has a ventilator and a diverter that connects to a basin access. The toilet bowl has a basin inlet and a dry outlet that connect to the ventilator. The toilet also has a flush tank with a wet inlet and a dry outlet that are connected to the ventilator. The toilet bowl has a basin access through the wet inlet and dry outlet. The patent also describes a flush tank insert and a diverter for the toilet flush tank. The toilet is designed to draw air through the wet inlet and flush out air through the dry outlet, which helps to keep the toilet clean and odour-free."

Problems solved by technology

The odours and bacteria are generally considered undesirable.

Each, however, poses a number of problems, such as, the toilet design being too complex and expensive to manufacture (cost prohibitive), or having a large number of moving parts (maintenance prohibitive), or requiring excessive reconfiguration of an existing toilet facility.
