Dispensing device of washing agents for a dishwashing machine, of the type comprises a body (2) to be fastened to a surface or wall delimiting a washing tub, having at least a portion of said body (2) protruding inside the washing tub; said dispenser (1) has at least a tank (11) for containing a liquid washing agent, means for dosing and/or dispensing a dose of liquid washing agent, a filling port (10) through which the liquid washing agent can be introduced into the tank (11), and closing means (15) of the filling port (10). According to the invention, the closing means (15) are capable of at least two different operating positions, where in one position they are apt to receive the liquid washing agent and direct it or convey it to the filling port (10), in order to fill the tank (11).
A dispensing device for washing agents for a dishwashing machine, of the type comprising a body (2) to be fastened to a surface or wall delimiting a washing tub, at least a portion of said body (2) protruding inside said washing tub;
A device according at least to one of the previous claims, characterized in that it provides stopping means for limiting the movement of said closing means (15) and/or said first sealing means (16) towards the outside of said filling port (10).
A device according at least to one of the previous claims, characterized in that said closing means comprise a movable element (15) delimiting a recess being apt to receive the liquid washing agent from above, in particular said element (15) being substantially designed as a sliding drawer.
A device according at least to one of the previous claims, characterized in that said first sealing means (GD2) and said second sealing means (GD1) are integrated as a single sealing element (GD).
A device according to the previous claim, characterized in that said single sealing element (GD) has at least
A device according at least to one of the previous claims, characterized in that said first sealing means (16;GD2) and/or said second sealing means (14;GD1) and/or said single sealing element (GD) are obtained by overmolding or co-molding or upsetting process of an elastic material on said body (2).
A device according at least to one of the previous claims, characterized in that said closing means or movable element (15), comprise an inclined bottom wall (15A).
A device according at least to one of the previous claims, characterized in that said closing means or movable element (15) comprise a rear wall (15B), fitted at least with a port (15B′), through which the liquid washing agent can flow from said recess to said duct (10A) and/or said tank (11).
A device according to the previous claim, characterized in that it provides a plurality of said ports (15B′) having a smaller section, in particular for obtaining a filtering element of the liquid washing agent.
A device according to the previous claim, characterized in that said closing means or movable element (15) comprise at least a length of upper wall (15E), whereon said first sealing means (GD2) operate when said closing means or movable element (15) are in said first operating position.
A device according at least to one of the previous claims, characterized in that said constraint means (15C′,15C″,18) comprise one or more extensions (15C′) of said closing means or movable element (15).
A device according at least to one of the previous claims, characterized in that said constraint means (15C′,15C″,18) comprise one or more guides (18) associated to said cover (5), wherein at least a portion (12C″) of said extensions (12C′) is engaged and capable of movement.
A device according at least to one of the previous claims, characterized in that said body (2) is obtained by welding a front piece and rear piece together, which are obtained from thermoplastic material.
A device according at least to one of the previous claims, characterized in that it provides indicator means (PA), for signaling a maximum filling level of said tank (11).
A device according to the previous claim, characterized in that said indicator means (PA) are delimited or integrated in said closing means or conveying means or movable element (15).
A dishwashing machine comprising a washing tub and a dispensing device for washing agents fastened to a surface or wall delimiting said tub, characterized in that said dispensing device is obtained according to one or more of the previous claims.
A method of filling a tank apt to contain a liquid washing agent in a dispensing device of a dishwashing machine, said dispensing device (1) being of the type comprising at least:
A method according to the previous claim, characterized in that said positioning of said closing means (5,15,17) comprises the positioning of conveying means (15) belonging to said closing means (5,15,17) in at least an opening position wherein said sealing means (16;GD2) are operating between at least part of said body (2) and said conveying means (15) to avoid said leakage of the liquid washing agent.
A method according to one or more of the previous claims from 43 to 46, characterized in that said step comprises the positioning of a movable element (15), belonging to said closing means (5,15,17), that is drawn through said filling port (10) from at least a first operating position, wherein a substantial portion of said closing means (15) is housed inside said body (2), up to at least a second operating position, wherein said substantial portion is located outside said body (2).
