Tub for washer or washer/dryer machine provided with conduits

Abstract

A tub ( 1 ) for washer or washer/dryer machine is disclosed, comprising: a tub body composed of a basically cylindrical lateral wall ( 20 ) connected by means of a circular connection section ( 21 ) to a bottom wall ( 2 ) and a cover ( 3 ) provided with a circular peripheral section ( 31 ) coupled with said bottom wall ( 2 ) of the tub body in such a way to form a box-shaped structure. The tub body comprises a first flange ( 25 ) that is coupled with a second flange ( 35 ) provided in said cover to generate a fluid-tight chamber ( 40 ) that can be used for various functions of the machine, such as pressure intake cover ( 4 ).

1 . Tub ( 1 ;  101 ) for washer or washer/dryer machine comprising:
 a tub body composed of a basically cylindrical lateral wall ( 20 ) connected by means of a circular connection section ( 21 ) to a flat bottom wall ( 2 ), and   a cover ( 3 ) provided with a circular peripheral section ( 31 ) coupled with the said bottom wall ( 2 ) of the tub body, in such a way to form a box-shaped structure,
 characterised in that 
   the tub body comprises at least a first flange ( 25 ;  125 ) that is coupled with at least a second flange ( 35 ;  135 ) provided in the said cover, in such a way to generate a fluid-tight chamber ( 40 ) or conduit ( 60 ) that can be used for pressure intake cover ( 4 ) or conduit ( 6 ) for passage of fluid.   
   
   
       2 . Tub ( 1 ;  101 ) according to  claim 1 , characterised in that the first flange ( 25 ;  125 ) is arranged on the said connection section ( 21 ) of the tub body and the second flange ( 35 ;  135 ) is arranged on said peripheral section ( 31 ) of the cover. 
   
   
       3 . Tub ( 1 ;  101 ) according to  claim 1 , characterised in that at least one between the said first flange ( 25 ;  125 ) and said second flange ( 35 ;  135 ) is provided with a recessed housing ( 26 ;  226 ) or concave cavity ( 136 ) to define the said chamber ( 40 ) or conduit ( 60 ). 
   
   
       4 . Tub ( 1 ) according to  claim 3 , characterised in that the first flange ( 25 ) protrudes radially from the connection section ( 21 ) of the tub body and has a recessed housing ( 26 ) and the second flange ( 35 ) protrudes radially from the said peripheral section ( 31 ) of the cover and has a shank ( 36 ) with a hole to receive a pipe ( 5 ) connected to a pressure switch. 
   
   
       5 . Tub ( 1 ) according to  claim 3 , characterised in that the first flange ( 25 ) protrudes radially from the connection section ( 21 ) of the tub body and has a hole ( 225 ) that communicates with the inside of the tub and the second flange ( 35 ) protrudes radially from the said peripheral section ( 31 ) of the cover and has a recessed housing ( 226 ) and a shank ( 36 ) with a hole to receive a pipe ( 5 ) connected to a pressure switch. 
   
   
       6 . Tub ( 101 ) according to  claim 3 , characterised in that:
 the first flange ( 125 ) follows the connection section ( 21 ) of the tub body for an arc of a circle of approximately 80°-120°and has a first end ( 127 ) that protrudes radially outwards and a second end with a hole ( 128 ) that communicates with a conduit ( 129 ) obtained on the said cylindrical lateral wall ( 20 ) of the tub body, and   the second flange ( 135 ) follows the peripheral section ( 31 ) of the cover for an arc of circle of approximately 80°-120°and is provided with a first end ( 137 ) that protrudes radially outwards and has a shank ( 7 ) with an inlet opening ( 70 ) and a second end with a cap ( 138 ) that covers the hole ( 120 ) of the first flange.   
   
   
       7 . Tub ( 1 ;  101 ) according to  claim 1 , characterised in that said at least first flange ( 25 ;  125 ) is integral with said tub body obtained by moulding of plastic materials. 
   
   
       8 . Tub ( 1 ;  101 ) according to  claim 1 , characterised in that said at least first flange ( 35 ;  135 ) is integral with said tub body obtained by moulding of plastic materials.
