Device and procedure for disinfecting a toilet appliance

Abstract

The invention is directed to a procedure for disinfecting a toilet appliance in which water for flushing a toilet ( 1 ) is introduced from a cistern ( 9 ) into a flush pipe ( 7 ) and from there into the interior of the toilet ( 1 ). The water is channeled through an ozone generator ( 11 ), where it is enriched with ozone and flows on as ozone water containing dissolved ozone and ozone gas bubbles before it enters the cistern ( 9 ). The cistern ( 9 ) is filled with the ozone water up to a pre-determined water level ( 35 ) and the ozone gas bubbles in the ozone water rise into the gas space above the water level ( 35 ) so that when the cistern ( 9 ) is filled up to the pre-determined water level ( 35 ), a piston effect is exerted by the rising water level ( 35 ) which guides the ozone gas into the flush pipe ( 7 ) and from there into the interior of the toilet ( 1 ). The procedure according to the present invention may be used for disinfecting public toilets, toilets in airplanes, ships, trains and busses, in hospitals, nursing homes and other care institutions. The invention is also directed to a device for disinfecting a toilet appliance with a toilet which is connected to a cistern ( 9 ) via a flush pipe ( 7 ), whereby an ozone generator ( 11 ) is arranged upstream of the cistern ( 9 ). An ozone converter ( 33 ) is arranged between the ozone generator ( 11 ) and the cistern ( 9 ) and an immersion pipe ( 27 ) is arranged in the cistern to introduce water for flushing into the cistern ( 9 ), whereby the immersion pipe is formed as a pipe reactor ( 127 ).

1 . A procedure for disinfecting a toilet appliance in which water for flushing a toilet is introduced from a cistern into a flush pipe and from there into the interior of the toilet, whereby the water is channeled through an ozone generator, where it is enriched with ozone and flows on as ozone water containing dissolved ozone and ozone gas bubbles before it enters the cistern wherein the cistern is filled with the ozone water up to a pre-determined water level and the ozone gas bubbles in the ozone water rise into the gas space above the water level so that when the cistern is filled up to the pre-determined water level, a piston effect is exerted by the rising water level which guides the ozone gas into the flush pipe and from there into the interior of the toilet. 
     
     
         2 . The procedure as in  claim 1 , wherein the ozone-enriched water passes through the ozone generator and then flows through an ozone converter before it enters the cistern, and that the ozone converter partially converts the ozone dissolved in the water into hydrogen peroxide by means of a catalytically active filling. 
     
     
         3 . The procedure as in  claim 1 , wherein the ozone gas introduced into the flush pipe and from there into the interior of the toilet is introduced into the flush pipe and the interior of the toilet as damp ozone gas. 
     
     
         4 . The procedure as in  claim 3 , wherein the ozone gas in the immersion pipe is saturated with water vapor. 
     
     
         5 . The procedure as in  claim 1 , wherein the toilet appliance has gap regions into which the ozone gas flows, and that it has openings through which the ozone gas flows into the vicinity of the toilet appliance. 
     
     
         6 . The procedure as in  claim 1 , wherein the water supply to the cistern is stopped as soon as the pre-determined water level is reached and that ozone production in the ozone generator is then stopped automatically. 
     
     
         7 . The procedure as in  claim 1  for disinfecting public toilets, toilets in airplanes, ships, trains and busses, in hospitals, nursing homes and other care institutions. 
     
     
         8 . A device for disinfecting a toilet appliance with a toilet which is connected to a cistern via a flush pipe, whereby an ozone generator is arranged upstream of the cistern, wherein an ozone converter is arranged between the ozone generator and the cistern and an immersion pipe is arranged in the cistern to introduce water for flushing into the cistern, whereby the immersion pipe is formed as a pipe reactor. 
     
     
         9 . The device as in  claim 8 , wherein the pipe reactor is formed as a coil to lengthen the route taken by the water inside the pipe reactor. 
     
     
         10 . The device as in  claim 8 , wherein the pipe reactor has a filling to decrease the flow rate of the water in the pipe reactor. 
     
     
         11 . The device as in  claim 8 , wherein the toilet has a lid. 
     
     
         12 . The device as in  claim 8 , wherein the converter has a filling, and that the filling is selected from copper oxide, platinum group metals, oxides of transition metals or compounds thereof. 
     
     
         13 . The device as in  claim 12 , wherein the catalytically active filling is selected from a mixture containing manganese dioxide and copper oxide, in particular hopcalite.
