Definitions

• the present invention relates to a detergent dosing system suitable for use in washing machines and a detergent saving method.
• detergent dosing systems are designed requirement-specific. Liquid detergent use is increasing due to reasons such as liquid detergents with varying features for various laundry types getting more common and rinsing thereof being easier.
• liquid detergent detergent dosing systems are used that don't have a powder detergent compartment.
• powder detergent is preferred particularly due to its better cleaning effect for white cotton laundry items. Therefore, in washing machines, an additional powder detergent compartment is demanded even when there is a liquid detergent dosing unit.
• a detergent box having both a liquid detergent compartment and a powder detergent compartment is disclosed in the patent application no. WO2015032658 (A1).
• Floating ball-valve systems are used in an interconnecting hose of a tub discharge pump at a tub outlet in order to use powder or liquid detergent efficiently.
• the ball-valve in the interconnecting hose between the tub and discharge pump closes the outlet of the tub by being raised by the water in the interconnecting hose.
• water with detergent is received while the ball-valve is raised, all of the detergent is enabled to be used during washing by being kept in the tub.
• the aim of the present invention is to realize a washing machine comprising a detergent dosing system enabling taking in detergent-free water, and a detergent saving method.
• the detergent box of the washing machine realized to achieve the aim of the present invention, three separate compartments are provided in which liquid detergent, softener, and, depending on a user's preference, powder detergent is placed.
• the washing machine of the invention comprises a by-pass line provided between the detergent drawer and the detergent box, by-passing the powder detergent compartment and the liquid agent (liquid detergent or softener) dosing chamber, enabling the water received from outside to be sent directly through the detergent box to the tub without mixing with the powder detergent and/or the dosed liquid agents.
• the washing machine further comprises a second valve enabling directing the water received from outside to the by-pass line, and a second water inlet connected to the second valve.
• the first valve and the second valve are of integral structure and have a common water inlet connected to an external cold water tap, composing a dual valve group with a single inlet and two outlets, with the first valve's outlet connected to the first water inlet and the second valve's outlet connected to the second water inlet.
• the washing machine has an external hot water connection
• the second valve has a single inlet and a single outlet, with its inlet connected to the hot water tap out of the washing machine.
• Figure 1 is a schematic view of a washing machine.
• Figure 2 is a schematic view of a detergent dosing system.
• Figure 3 is a schematic view of the detergent dosing system and the tub discharge group in an embodiment of the invention.
• Figure 4 is a schematic view of the detergent dosing system and the tub discharge group in another embodiment of the invention.
• the washing machine (1) comprises a tub (2) in which washing-drying processes are performed, a drum (3) rotating in the tub (2), in which laundry items are placed, and a detergent dosing system (25) having a detergent drawer (7) comprising a liquid detergent compartment (4) in which liquid detergent is stored, a softener compartment (5) in which softener is stored and a powder detergent compartment (6) in which powder detergent is placed depending on a user's preference, a detergent box (9) in which the detergent drawer (7) is placed, having a tub outlet (8) transmitting water to the tub (2), a dosing pump (10) enabling the liquid detergent and the softener (hereinafter both referred to as the "liquid agents") stored in the detergent drawer (7) to be dosed so as to be sent to the washing environment in the tub (2) in predetermined amounts for main washing and rinsing processes, a liquid agent dosing chamber (12) provided at a cover (11) on the detergent box (9) or on the dosing pump (10), a first valve (13) enabling receiving water from outside for
• the washing machine (1) of the invention comprises,
• the first valve (13) and the second valve (16) are of integral structure and have a common water inlet connected to an external cold water tap (23), composing a dual valve group with a single inlet and two outlets, with the first valve's (13) outlet connected to the first water inlet (14) and the second valve's (16) outlet connected to the second water inlet (17).
• the second valve (16) has a single inlet and a single outlet, and is controlled independent of the first valve (13).
• the washing machine (1) has an external hot water connection
• the second valve (16) has a single inlet and a single outlet, with its inlet connected to a hot water tap (24) out of the washing machine (1).
• the washing machine (1) comprises
• a detergent saving method (or a detergent escape prevention method) known as “ball-valve (22) closing algorithm” is applied in order to enable the ball-valve (22) to firmly press on the water outlet port (18) before washing process begins, and to prevent powder detergent or liquid detergent to be transmitted to the tub (2) from being wasted without being used in washing by escaping from the water outlet port (18).
• Said detergent saving method comprises the steps of:
• “ball-valve (22) closing algorithm” is applied by receiving “detergent-free” water to the tub (2) before washing process begins, by way of second valve (16)-second water inlet (17)-by-pass line (15)-tub outlet (8).
• the water received from outside by way of second valve (16)-second water inlet (17)-by-pass line (15), is used for cleaning the detergent box (9).
• the water received from outside by way of second valve (16)-second water inlet (17)-by-pass line (15)-tub outlet (8) is used for complementing the water level decreasing due to being sucked by the laundry items.
• the decreasing water level in the tub (2) may also be complemented with the water received from the first valve (13).
• the detergent-free water in an amount required for the ball-valve (22) in the interconnecting hoe (21) to sufficiently firmly close the water outlet port (18) before powder detergent or liquid detergent is received in the tub (2) is also received via the detergent box (9) by way of second valve (16)-second water inlet (17)-by-pass line (15)-tub outlet (8).
• second valve (16)-second water inlet (17)-by-pass line (15)-tub outlet (8) is also received via the detergent box (9).
• the duration of a washing program can be shortened by increasing the flow rate of the second valve (16) because the receive water with high flow rate by-passes the liquid agent dosing chamber (12) or the powder detergent compartment (6), eliminating the risks of foaming or overflowing of the detergent from the detergent box (9).
• the water intake sound disturbing the user can be decreased by decreasing the flow rate of the second valve (16).
