Air flush system

Abstract

An airflush system comprises a bowl, a seat, a seat cover, a pair of gaskets, and an air pressure device. The bowl has an interior configured to receive waste, a bowl rim forming an opening through which the waste is received into the bowl, and an exit pipe through which the waste is discharged from the bowl. The seat has an opening and is configured to rest on the bowl rim such that the opening communicates with the interior of the bowl. The first gasket is disposed between the seat and the bowl rim such that when the seat rests on the bowl rim the first gasket forms an airtight seal between the seat and the bowl rim. The a cover is configured to rest on the seat to cover the opening of the seat, the cover having a hole. The second gasket is disposed between the cover and the seat such that when the cover rests on the seat the second gasket forms an airtight seal between the cover and the seat. The air pressure device introduces pressurized air into the interior of the bowl via the hole of the cover while the seat rests on the bowl rim and the cover rests on the seat to discharge the waste in the interior of the bowl through the exit pipe.

         5 . An airflush system according to  claim 2 ; further comprising an airflow diffuser disposed on an underside of the cover for deflecting the air flow from the air pressure device towards the interior of the bowl. 
     
     
         6 . An airflush system according to  claim 5 ; wherein the air pressure device has a hose via which the pressurized air is delivered; and further comprising an adaptor connected between the hose of the air pressure device and the hole of the cover. 
     
     
         7 . An airflush system according to  claim 2 ; wherein the hole is formed at a rear of the cover. 
     
     
         8 . A toilet comprising:
 a bowl having an interior configured to receive waste, a bowl rim forming an opening through which the waste is received into the bowl, and an exit pipe through which the waste is discharged from the bowl;   a seat having an opening and being configured to rest on the bowl rim such that the opening communicates with the interior of the bowl;   a first gasket disposed between the seat and the bowl rim such that when the seat rests on the bowl rim the first gasket forms an airtight seal between the seat and the bowl rim;   a cover configured to rest on the seat to cover the opening of the seat;   a second gasket disposed between the cover and the seat such that when the cover rests on the seat the second gasket forms an airtight seal between the cover and the seat; and   means defining an opening in the cover through which pressurized air is introduced into the interior of the bowl while the seat rests on the bowl rim and the cover rests on the seat to discharge the waste in the interior of the bowl through the exit pipe.   
     
     
         9 . A toilet according to  claim 8 ; wherein the first gasket is disposed around an entire bottom edge of the seat. 
     
     
         10 . A toilet according to  claim 8 ; wherein the means defining an opening comprises a hole formed in the cover. 
     
     
         11 . A toilet according to  claim 10 ; wherein the hole is formed at a rear of the cover. 
     
     
         12 . A seat/cover unit for a toilet having a bowl with an interior configured to receive waste, a bowl rim forming an opening through which the waste is received into the bowl, and an exit pipe through which the waste is discharged from the bowl, the seat/cover unit comprising:
 a seat having an opening and a first gasket, the seat being configured to rest on the bowl rim such that the opening communicates with the interior of the bowl and the first gasket forms an airtight seal between the seat and the bowl rim; and   a cover for covering the opening of the seat, the cover having a gasket that is disposed between the cover and the seat when the cover covers the opening of the seat to form an airtight seal between the cover and the seat, and the cover having a hole communicating with the interior of the bowl via the opening of the seat when the cover covers the seat and through which pressurized air is supplied to discharge waste in the interior of the bowl through the exit pipe.   
     
     
         13 . A seat/cover unit according to  claim 12 ; wherein the first gasket is disposed around an entire bottom edge of the seat. 
     
     
         14 . A seat/cover unit according to  claim 12 ; wherein the hole is formed at a rear of the cover.
