Washing device with sponge-like working element

Abstract

A washing device has a housing having an axis and a peripheral wall which defines an inner hollow and is closed in a peripheral direction around the axis, and a sponge-like working element associated with the housing and movable between a working position in which the sponge-like working element is located outside the hollow of the housing for washing a surface, and a position in which the sponge-like working element is forcedly moved into the hollow formed by the peripherally closed wall so as to be squeezed and therefore to expel liquid from the sponge-like working element and to remain confined within said inner hollow enclosed by said peripheral wall.

1 . A washing device, comprising a housing having an axis and a peripheral wall which defines an inner hollow and is closed in a peripheral direction around said axis; and a sponge-like working element associated with said housing and movable between a working position in which said sponge-like working element is located outside said hollow of said housing for washing a surface, and a position in which said sponge-like working element is forcedly moved into said hollow formed by said peripherally closed wall so as to be squeezed and therefore to expel liquid from said sponge-like working element and to remain confined within said inner hollow enclosed by said peripheral wall.  
   
   
       2 . A washing device as defined in  claim 1;  and further comprising a displacing element which is connected with said sponge-like working element and displaces said sponge-like working element between said positions.  
   
   
       3 . A washing device as defined in  claim 2 , wherein said displacing element is turnable about said axis so that when said displacing element moves said sponge-like working element from said inner hollow to said working position, said displacing element is turnable and turns said sponge-like working element about said axis.  
   
   
       4 . A washing device as defined in  claim 3 , wherein said housing is provided with means for squeezing said working element during turning said working element about said axis.  
   
   
       5 . A washing device as defined in  claim 1 , wherein said means for squeezing include at least one formation projecting into said hollow and formed so that when said sponge-like working element is turned it is squeezed by overcoming a resistance of said at least one formation.  
   
   
       6 . A washing device as defined in  claim 5 , wherein said at least one formation is formed as a rib provided on an inner surface of said housing and extending inwardly into said hollow.  
   
   
       7 . A washing device as defined in  claim 2 , wherein said displacing element is hollow and fillable with a washing substance.  
   
   
       8 . A washing device as defined in  claim 7;  and further comprising means for dispensing the substance from said displacing element onto a surface to be washed.  
   
   
       9 . A washing device as defined in  claim 2 , wherein said housing has two axial ends and is closed at at least one of said axial ends by said displacing element; and further comprising means for closing said housing at the other axial end after said sponge-like working element is moved to said non-working position inside said hollow of said housing.  
   
   
       10 . A washing device as defined in  claim 1;  and further comprising a container for accommodating said sponge-like working element before a next use.  
   
   
       11 . A washing device as defined in  claim 10 , wherein said container is associated with said housing so that a part of said housing closes said container.  
   
   
       12 . A washing device as defined in  claim 10;  and further comprising suction means from attaching a bottom of said container to a supporting surface, said suction means being actuatable by a displacing element which is connected with said sponge-like working element and displaces said sponge-like working element between said positions.  
   
   
       13 . A washing device as defined in  claim 1;  and further comprising a connecting element which connects said sponge-like working element and is provided with a brush-shaped portion.
