- an impeller (11) that has more than one impeller fin (10), that rotates around its axis as the water taken from the dosing water inlet (9) strikes the fins (10) thereof and that, by transferring the rotational movement to the hydraulic pump (8), enables the hydraulic pump (8) to be operated with the dynamic pressure of the water without the need for consuming electrical energy (
Figure 5 ,Figure 8 ). - In an embodiment of the present invention, the hydraulic pump (8) is a gear pump that consists of a drive gear (12) and a driven gear (13) that operate in unison. In this embodiment, the impeller (11) rotates the drive gear (12) in the hydraulic pump (8) around the same axis as that of the impeller (11) by means of a long shaft (14). The drive gear (12) transfers the movement to the driven gear (13) and enables the hydraulic pump (8) to be operated (
Figure 5 ,Figure 7 ). - The dosing unit (1) comprises a pump chamber (16) that is fluidly connected to the receptacle (3) by means of at least one control valve (15) when the detergent dispenser (4) is placed into the housing (6) and wherein the drive gear (12) and the driven gear (13) are disposed and the liquid materials are filled for being dosed; an impeller chamber (17) wherein the impeller (11) rotates with the effect of dynamic pressure of the water taken from the dosing water inlet (9) and striking the impeller fins (10); a separator (18) that separates the pump chamber (16) and the impeller chamber (17); a short shaft (19) with one end connected to the separator (18), that enables the driven gear (13) to be idly supported so as to rotate around its axis; a sealing element (20) such as gasket or felt that is arranged around the hole through which the long shaft (14) in the separator (18) passes and that provides sealing between the pump chamber (16) and the impeller chamber (17) so as to prevent the mixing of the liquid materials and water; an inlet orifice (21) that provides liquid material intake from the receptacle (3) into the pump chamber (16) so as to be dosed; a detergent transfer tube (22) that extends from the pump chamber (16) towards the housing (6) and that enables the liquid materials moved by the hydraulic pump (8) to be swept with water and transferred to the housing (6) before being transferred to the tub (2), and a water discharge hole (23) that enables the water in the impeller chamber (17) rotating the impeller (11) to be discharged and transferred to the housing (6) (
Figure 5 ). - The detergent transfer tube (22) extends vertically from the pump chamber (16) up to a level above the level of the liquid material stored in the receptacle (3) and bends downwards so as to provide the transfer of the liquid material to the housing (6) (
Figure 4 ,Figure 5 ,Figure 6 ). Thus, the liquid material transferred from the detergent dispenser (4) to the pump chamber (16) is prevented from continuing their flow with the effect of gravity and being discharged (unnecessarily flowing) into the housing (6) when the hydraulic pump (8) is not performing the dosing function, and only the amount of the liquid material that is dosed during the operation of the hydraulic pump (8) is enabled to reach the housing (6). - The washing machine (7) comprises two dosing units (1) one of which is used for dosing the liquid detergent and the other for dosing the softener, and at least one valve (25) that directs the water taken from the water mains through the first water inlet (9) to the first dosing unit (1) in order to be used in liquid detergent dosing or through the second dosing water inlet (9) to the second dosing unit (1) in order to be used in softener dosing (
Figure 1 ). - The washing machine (7) further comprises a washing water inlet (24) that is arranged on the housing (6), that enables the water taken from the mains for the main washing and rinsing processes to be transferred into the housing (6) and the liquid materials that are previously dosed and accumulated on the base of the housing (6) to be swept with water and transferred to the washing environment in the tub (2) through the tub outlet (5) (
Figure 1 ,Figure 2 ). - In the washing machine (7), liquid detergent in a predetermined amount according to the washing program is dosed in the main washing process and softener in a predetermined amount is dosed in the rinsing process. In the dosing process, water at a predetermined flow rate and amount is taken through the dosing water inlet (9) into the impeller chamber (16) in the dosing unit (1) and the impeller (11) is enabled to be rotated with the water hitting the impeller fins (10). The impeller (11) actuates the drive gear (12) in the hydraulic pump (8) by transferring movement by means of the long shaft (14), and the liquid materials that are taken from the receptacle (3) and dosed are transferred into the housing (6) by means of the detergent transfer tube (22). Then, the dosed liquid water accumulating on the base of the housing (6) are swept with the water taken through the washing water inlet (24) and transferred to the washing environment in the tub (2) through the tub outlet (5).
- In another embodiment of the present invention, the washing machine (7) comprises a powder detergent receptacle (26) that is arranged in the detergent dispenser (4) and wherein the powder detergent is placed; an auxiliary water inlet (27) that is arranged on the housing (6) and that enables the powder detergent to be swept with the water taken from the water mains and transferred into the washing environment in the tub (2) through the tub outlet (5), and an air discharge tube (28) that is arranged on the housing (6) and that enables the air to be discharged during the washing process (
Figure 2 ). - In an embodiment of the present invention, the valve (25) is a multi-way valve that has one inlet and a plurality of outlets (for example, four outlets) and enables, in addition to the water directed to the first and second dosing water inlets (9), the water taken from the water mains to be directed towards the washing water inlet (24) and/or towards the auxiliary water inlet (27) for the transfer of the powder detergent.
- The control unit (not shown in figures) regulates the operation of the valve (25) for the processes of dosing liquid detergent and softener, taking water during the washing and rinsing steps and sweeping the powder detergent, and enables the valve (25) to direct water at predetermined times and in predetermined amounts to the first and second dosing water inlets (9), the washing water inlet (24) and the auxiliary water inlet (27).
- In the washing machine (7) of the present invention, the liquid detergent and the softener are precisely dosed and transferred into the washing environment in the tub (2). The hydraulic pump (8) used for dosing is operated by means of an impeller (11) rotated by the water taken from the water mains instead of electrical energy. Thus, the need for using cables, etc. to operate the hydraulic pump (8) is eliminated, reducing the cost of the system.
