[0044] The dishwasher (1) comprises a body (2); a washing cabin (3) disposed on the body (2) and wherein the washing process is performed; a detergent dispenser (4) that is detachably mounted on the body (2) and wherein liquid/gel detergent can be filled; a detergent receptacle (5) that is disposed inside the detergent dispenser (4) and wherein detergent is filled; a scaling receptacle (6) that is disposed next to the detergent receptacle (5) and wherein the detergent to be used in the washing process is transferred from the detergent receptacle (5) and collected; at least one first opening (7) that is arranged between the detergent receptacle (5) and the scaling receptacle (6) and that enables the detergent to be transferred from the detergent receptacle (5) to the scaling receptacle (6); at least one second opening (8) that is arranged between the scaling receptacle (6) and the washing cabin (3) and that enables the detergent to be transferred from the scaling receptacle (6) to the washing cabin (3); at least one gasket (10) that is seated on the openings (7, 8) and that provides leak proofing, and a dosing mechanism (9) that is disposed between the detergent receptacle (5) and the scaling receptacle (6) and that enables the detergent to be transferred from the detergent receptacle (5) towards the washing cabin (3) by controlling opening/closing of the first opening (7) and the second opening (8). The detergent filled by the user and stored in the detergent receptacle (5) is transferred by the dosing mechanism (9) during the washing process from the detergent receptacle (5) towards the washing cabin (3). The amount of detergent required for the washing program is delivered to the scaling receptacle (6) by passing through the first opening (7). The detergent transferred to the scaling receptacle (6) is delivered to the washing cabin (3) by passing through the second opening (8).

[0045] The dishwasher (1) furthermore comprises a first valve (11) having a gasket (10) thereon for closing the first opening (7), a second valve (12) having a gasket (10) for closing the second opening (8), and the dosing mechanism (9) that enables at least one opening (7, 8) to be almost entirely closed during transfer of detergent from the detergent receptacle (5) to the washing cabin (3). As the first opening (7) is closed by the first valve (11), the detergent flow from the detergent receptacle (5) towards the scaling receptacle (6) is cut off. As the second opening (8) is closed by the second valve (12), the detergent flow from the scaling receptacle (6) towards the washing cabin (3) is cut off. When the first opening (7) is closed, the second opening (8) is opened and when the second opening (8) is closed, the first opening (7) is opened. Thus, a cycle is completed. As the piston rod (14) completes one full rotation on the crankshaft (13), the first opening (7) and the second opening (8) are enabled to be closed at the same time between the lowest and highest points. Accordingly, the openings (7, 8) are enabled to be controlled more easily and during the transfer of the liquid detergents with high viscosity the amount of detergent is enabled to be controlled. During one full cycle of the dosing mechanism (9), each of the first opening (7) and the second opening (8) is opened and closed only once by itself. During the cycle, the two openings (7, 8) are closed twice at the same time.

[0046] In an embodiment of the present invention, the dishwasher (1) comprises a crankshaft (13) disposed on the detergent receptacle (5) in the direction of the first opening (7) and the second opening (8); a piston rod (14), one end of which is fastened to the crankshaft (13) and the other end extending towards the scaling receptacle (6); a first support member (15), one end of which is fastened to the piston rod (14) moving in the vertical direction; a second support member (16) that is connected to the first support member (15), that has the second valve (12) thereon and that moves together with the first support member (15) in the vertical direction; the first valve (11) mounted to the second support member (16) so as to move on the second support member (16); a first spring (17) disposed between the first support member (15) and the second support member (16), and a second spring (18) disposed between the first valve (11) and the second valve (12). The piston rod (14) moves in the vertical direction as the crankshaft (13) rotates. As the piston rod (14) moves downwards, the first support member (15), one end of which is connected to the piston rod (14), also moves downwards. Thus, the first valve (11) moving in the vertical direction on the second support member (16) enables the first opening (7) to be opened by moving downward and detergent to be transferred from the detergent receptacle (5) towards the scaling receptacle (6). By means of the piston rod (14) moving upwards, the second support member (16) is pulled upwards and enables the second openings (8) to be opened. By means of the first spring (17) and the second spring (18), movement of the valves (11, 12) is facilitated.

[0047] In an embodiment of the present invention, the dosing mechanism (9) comprises a stopper (19) that is disposed on the first support member (15), that exerts pressure on the first valve (11) when the piston rod (14) moves downwards and that enables the first valve (11) to compress the second spring (18) and the first opening (7) to be opened. When the piston rod (14) moves downwards, the first support member (15) is pushed downwards by the piston rod (14).

[0048] The stopper (19) situated on the first support member (15) contacts the first valve (11) and pushes the first valve (11) downwards. The first valve (11) that can move in the vertical direction moves downwards by sliding on the second support member (16). Thus, the first opening (7) is enabled to be opened.

[0049] In an embodiment of the present invention, the dosing mechanism (9) comprises a grasper (20) that is disposed on the first support member (15), that grasps the second support member (16) when the piston rod (14) moves upwards and enables the same to move in the upward direction and that enables the second spring (18) to be compressed between the first valve (11) and the second valve (12). When the piston rod (14) moves upwards, the first support member (15) is pulled upwards by the piston rod (14). By means of the first support member (15) moving upwards, the second spring (18) is opened and pushes the first valve (11) upwards. Thus, the first opening (7) is enabled to be closed. After the first opening (7) is closed, the grasper (20) located on first support member (15) grasps the second support member (16) and enables the same to move upwards. Thus, the second valve (12), situated on the second support member (16) that moves upwards, enables the second opening (8) to be opened by moving upwards.

[0050] In an embodiment of the present invention, the dosing mechanism (9) enables the first opening (7) and the second opening (8) to be closed at the same time as the piston rod (14) moves on the crankshaft (13) between the lowest and highest points. When the piston rod (14) is at the lowest point on the crankshaft (13), the first valve (11) is pulled downwards and the first opening (7) is open. When the piston rod (14) starts to move towards the highest point on the crankshaft (13), the first support member (15) enables the first opening (7) to be closed by moving in the upward direction. However, the second opening (8) is not opened before the piston rod (14) comes to the lowest point on the crankshaft (13). Thus, the first opening (7) and the second opening (8) are enabled to be closed at the same time when the piston rod (14) is at the 90 and 270 positions on the crankshaft (13). Thus, the use of liquid detergents having high viscosity values during the cycle is facilitated.

[0051] In an embodiment of the present invention, the dishwasher (1) comprises the first spring (17) that pushes the second valve (12) downwards while the piston rod (14) moves on the crankshaft (13) between the lowest and highest points. When the piston rod (14) is between the lowest and highest points on the crankshaft (13), the second valve (12) is pushed downwards by the first spring (17). Thus, the second valve (12) closes the second opening (8) and the second opening (8) is enabled to remain closed until the piston rod (14) comes to the highest point on the crankshaft (13) .

[0052] In an embodiment of the present invention, the dishwasher (1) comprises the second spring (18) that pushes the first valve (11) upwards while the piston rod (14) moves on the crankshaft (13) between the lowest and highest points. When the piston rod (14) is between the lowest and highest points on the crankshaft (13), the first valve (11) is pushed upwards by the second spring (18). Thus, the first valve (11) closes the first opening (7) and the first opening (7) is enabled to remain closed until the piston rod (14) comes to the lowest point on the crankshaft (13).

[0053] In an embodiment of the present invention, the dishwasher (1) comprises a motor (21) that enables the crankshaft (13) to move. The crankshaft (13) rotates by being energized by the motor (21).

[0054] In an embodiment of the present invention, the dosing mechanism (9) enables one dose of detergent to be delivered to the washing cabin (3) as the piston rod (14) completes one full rotation on the crankshaft (13). In intensive washing programs, the dosing mechanism (9) performs more than one cycle and delivers several doses of detergent to the washing cabin (3).

[0055] By means of the present invention, high viscosity liquid detergent is enabled to be delivered to the washing cabin (3) by means of a dosing mechanism (9). The user fills in detergent into the dosing mechanism (9) and during washing, the detergent requirement is maintained by the dosing mechanism (9). Meanwhile, liquid detergents having high viscosity are enabled to be dosed controllably.
