By means of the dosing mechanism (7), the need for the detergent to be filled by the user in the dishwasher (1) at the beginning of each washing cycle is eliminated. The amount of detergent needed during the washing cycle is provided by automatically dosing the detergent filled in the detergent dispenser (4).

[0027] The dishwasher (1) of the present invention comprises a detergent receptacle (8) that is disposed in the detergent dispenser (4) and wherein the detergent is filled; a scaling receptacle (9) that is disposed next to the detergent receptacle (8) and wherein the detergent the amount of which is determined by the control unit (5) according to the selected program is transferred from the detergent receptacle (8); the dosing mechanism (7) that is disposed between the detergent receptacle (8) and the scaling receptacle (9) and that has an open position (A) wherein the flow of the detergent from the detergent receptacle (8) towards the scaling receptacle (9) is enabled, and a closed position (K) wherein the flow of the detergent is disabled; and the control unit (5) that controls the transition of the dosing mechanism (7) between the open (A) and closed (K) positions. During the washing process, the detergent to be transferred to the washing cabin (3) is first transmitted from the detergent receptacle (8) to the scaling receptacle (9). When the dosing mechanism (7) is in the open position (A), detergent transmission from the detergent dispenser (4) to the washing cabin (3) is not realized. The amount of detergent to be transferred is determined by the control unit (5) according to the density of the dishes. Thus, by automatically determining the amount of detergent according to the amount of dishes and the dirtiness ratio, the detergent can be delivered to the washing cabin (3) by means of the dosing mechanism (7). Thus, the dishes are enabled to be washed with the appropriate amount of detergent without requiring the user to add detergent before each washing. Thus, the user satisfaction is improved and the detergent consumption is realized at an optimum level.

[0028] In an embodiment of the present invention, the dishwasher (1) comprises at least one first opening (10) that is disposed between the detergent receptacle (8) and the scaling receptacle (9) and that enables the transmission of the detergent from the detergent receptacle (8) to the scaling receptacle (9); at least one second opening (11) that is disposed between the scaling receptacle (9) and the washing cabin (3) and that enables the transmission of the detergent from the scaling receptacle (9) to the washing cabin (3); a crankshaft (12) disposed on the detergent receptacle (8) in the direction of the first opening (11) and the second opening (12); a motor (6) the operation of which is controlled by the control unit (5) and that moves the crankshaft (12); a piston rod (13) one end of which is connected to the crankshaft (12), the other end extending in the direction of the scaling receptacle (9); a piston (14) that is disposed on the scaling receptacle (9) and that moves in the vertical direction as being connected to the piston rod (13); a support (24) that is connected to the piston (14) and that moves with the piston (14); and more than one gasket (15, 115) that is disposed on the upper and lower surfaces of the support (24) and that enables the dosing mechanism (7) to change to the open (A) and closed (K) positions depending on the movement of the piston (14). The motor (6) starts to operate according to the information received from the control unit (5). With the operation of the motor (6), the crankshaft (12) rotates and enables the piston rod (13) connected to the crankshaft (12) to move in the vertical direction. Thus, the piston (14) that is connected to the piston rod (13) and the support (24) that is connected to the piston (14) are enabled to move in the vertical direction. The gaskets (15,115) are enabled to open and close the first openings (10) or the second openings (11) depending on the movement direction of the support.

[0029] In an embodiment of the present invention, the dosing mechanism (7) comprises at least one first gasket (15) that is disposed on the upper surface of the support (24) and that enables the dosing mechanism (7) to change to the closed position (K) by enabling the first openings (10) to close when the piston (14) moves towards the detergent receptacle (8); and at least one second gasket (115) that enables the dosing mechanism (7) to change to the open position (A) by enabling the second openings (11) to close when the piston (14) moves towards the scaling receptacle (9). By means of the piston (14) moving in the vertical direction, the support (24) also moves in the vertical direction. By means of the support (24) moving downwards, the second gaskets (115) disposed in the lower part thereof close the second openings (11) and the dosing mechanism (7) is enabled to change to the open position (A). When the support (24) moves upwards, the gaskets (15) disposed in the upper part thereof close the first openings (10). Thus, the detergent is transferred from the scaling receptacle (9) towards the washing cabin (3) by enabling the dosing mechanism (7) to change to the closed position (K).

[0030] In an embodiment of the present invention, the dishwasher (1) comprises a door (16) disposed on the body (2); a stationary detergent distribution unit (23) that enables the use of powder or solid detergent and wherein detergent is filled in such an amount that the entire detergent can be used in a single washing cycle; and a detergent dispenser (4) disposed on the door (16) or the washing cabin (3).
