Waste water valve of a floor cleaning machine and floor cleaning machine

Abstract

A waste water valve for connection to the outlet of a waste water tank of a floor cleaning machine, having a pipe socket which has an inlet end and an outlet end, having a closure body which is mounted on the pipe socket so as to be displaceable between a closed position and an open position, having an actuating element which is mounted on the pipe socket so as to be adjustable between a closed position and an open position, which actuating element is rigidly coupled to the closure body in such a way that the closure body moves from the closed position to the open position when the actuating element moves from the closed position to the open position, and that the closure body moves from the open position to the closed position when the actuating element moves from the open position to the closed position.

1 . A waste water valve for connection to the outlet of a waste water tank of a floor cleaning machine
 having a pipe socket which has an inlet end and an outlet end, wherein the inlet end is designed to be connected to the outlet of the waste water tank and wherein the outlet end has a circumferential edge,   having a closure body which is mounted on the pipe socket so as to be displaceable between a closed position and an open position,   wherein the closure body is arranged in the closed position so that it closes the outlet end and is arranged in the open position at such a distance from the outlet end that a distance is provided between the closure body and the outlet end over the entire circumferential edge,   having an actuating element which is mounted on the pipe socket so as to be adjustable between a closed position and an open position, which actuating element is rigidly coupled to the closure body in such a way
 that the closure body moves from the closed position to the open position when the actuating element moves from the closed position to the open position, and 
 that the closure body moves from the open position to the closed position when the actuating element moves from the open position to the closed position, 
   wherein a biasing element is provided that biases the closure body towards the closed position.   
     
     
         2 . The waste water valve according to  claim 1 , wherein the closure body has a closure section which is shaped akin to a part of a spherical shell or a conical shell or a truncated conical shell,
 wherein the outlet end has a circular cross-section, and   wherein in the closed position, the closure section closes the outlet end.   
     
     
         3 . The waste water valve according to  claim 1 , wherein the pipe socket has a rubber sleeve on which the outlet end is formed. 
     
     
         4 . The waste water valve according to  claim 1 , wherein the pipe socket has a straight section extending from the outlet end to the inlet end,
 having a sleeve that surrounds the straight section and is mounted on the pipe socket so as to be displaceable along it,   wherein the closure body is fastened to the sleeve.   
     
     
         5 . The waste water valve according to  claim 4 , wherein the sleeve extends from a proximal end to a distal end,
 wherein the proximal end points towards the inlet end of the pipe socket,   wherein the distal end extends beyond the outlet end, and   wherein the closure body is at least partially arranged within the interior of the sleeve.   
     
     
         6 . The waste water valve according to  claim 5 , wherein a sealing ring is arranged at the distal end. 
     
     
         7 . The waste water valve according to  claim 5 , wherein a washing liquid outlet is provided on the sleeve adjacent to the closure body, which is designed such that washing liquid can be sprayed onto the closure body through it. 
     
     
         8 . The waste water valve according to  claim 7 , wherein the washing liquid outlet is arranged in the longitudinal direction of the sleeve so as to be positioned between the outlet end and the closure body in the axial direction of the sleeve when the closure body is in the open position. 
     
     
         9 . The waste water valve according to  claim 4 , wherein the actuating element is designed as an actuating lever, having an actuating section and a coupling section,
 wherein the actuating lever is mounted on the pipe socket so as to be pivotable between the actuating section and the coupling section about a pivot axis extending transversely to the straight section,   wherein the actuating lever can be pivoted between the closed position and the open position,   wherein the coupling section is connected to the sleeve such
 that the sleeve moves with the closure body from the closed position to the open position when the actuating lever pivots from the closed position to the open position, and 
 that the sleeve moves with the closure body from the open position to the closed position when the actuating lever pivots from the open position to the closed position. 
   
     
     
         10 . The waste water valve according to  claim 1 , wherein a washing liquid outlet is provided on the pipe socket, which is designed such that washing liquid can be introduced into the pipe socket through it. 
     
     
         11 . The waste water valve according to  claim 1 , further comprising a floor cleaning machine having a waste water tank, which has an outlet, wherein the outlet is connected to the waste water valve. 
     
     
         12 . The waste water valve according to  claim 11 , wherein the floor cleaning machine includes a housing, wherein the actuating element is arranged behind an opening in the housing in such a way that it can be moved from the closed position to the open position by inserting an actuator.
