Siphoning Group for Food Waste Disposers

Abstract

A siphoning group ( 10 ) for food waste disposers comprising a main duct ( 11 ) which can be connected upstream in a first end 11 a with a food waste disposer and downstream in a second end 11 b with a discharge tube, at least one derivation duct ( 12, 12 ′) connected to the main duct ( 11 ) between the upstream and downstream connections for the passage of water from at least another installation to said discharge tube, wherein the siphoning group ( 10 ) also comprises means for the selective isolation ( 13 ) of the at least one derivation duct ( 12, 12 ′) with respect to the main duct ( 11 ) during the use of the food waste disposer.

1 .

         2 . The siphoning group ( 10 ) according to  claim 1 , characterized in that said means of the selective isolation ( 13 ) of said at least one derivation duct ( 12 ,  12 ′) with respect to said main duct ( 11 ) can be removed during the use of said food waste disposer. 
     
     
         3 . The siphoning group ( 10 ) according to  claim 1 , characterized in that said means of the selective isolation ( 13 ) of said at least one derivation duct ( 12 ,  12 ′) with respect to said main duct ( 11 ), during the use of said food waste disposer, are a sleeve element ( 13 ) at least partially consisting of a deformable material inserted and fixed coaxially with respect to said main duct ( 11 ) in correspondence with said at least one derivation duct ( 12 ,  12 ′). 
     
     
         4 . The siphoning group ( 10 ) according to  claim 3 , characterized in that said sleeve ( 13 ) is removably fixed in said main duct ( 11 ) by means of an upper annular protrusion ( 14 ) which buffers against a relative seat ( 15 ) situated inside said main duct ( 11 ) above said at least one derivation duct ( 12 ,  12 ′). 
     
     
         5 . The siphoning group ( 10 ) according to  claim 3 , characterized in that said sleeve ( 13 ) is at least partly made of rubber. 
     
     
         6 . The siphoning group ( 10 ) according to  claim 3 , characterized in that said sleeve ( 13 ) is at least partly made of silicon. 
     
     
         7 . The siphoning group ( 10 ) according to  claim 1 , characterized in that said means of the selective isolation ( 13 ) of said at least one derivation duct ( 12 ,  12 ′) with respect to said main duct ( 11 ), during the use of said food waste disposer, are at least one valve element situated in correspondence with the connection of said at least one derivation duct ( 12 ,  12 ′) with said main duct ( 11 ). 
     
     
         8 . The siphoning group ( 10 ) according to  claim 7 , characterized in that it comprises two valve elements ( 13   a ,  13   b ) facing each other in correspondence with the connection of said at least one derivation duct ( 12 ,  12 ′) with said main duct ( 11 ), wherein each of said two valve elements ( 13   a ,  13   b ) comprises a sleeve portion ( 20   a ,  20   b ) assembled for at least a section in said at least one derivation duct ( 12 ,  12 ′) and a membrane ( 21   a ,  21   b ) constrained to the relative sleeve ( 20   a ,  20   b ), said membranes ( 21   a ,  21   b ) being movable starting from a first vertical rest position closing said at least one derivation duct ( 12 ,  12 ′), to a second oblique opening position facing the interior of said main duct ( 11 ) for the passage of water from said at least one derivation duct ( 12 ,  12 ′) to said main duct ( 11 ). 
     
     
         9 . The siphoning group ( 10 ) according to  claim 8 , characterized in that said sleeves  20   a ,  20   b  also internally comprise a slightly tilted funnel-type profile to accelerate the flow coming from said at least one derivation duct ( 12 ,  12 ′) towards said main duct ( 11 ).
