  • control unit optimizes the number of pumping, enabling the pump to perform more than one pumping so that the washing duration is not prolonged while the cleaning agent is pumped and in order to prevent formation of foam.
  • control unit enables the pump to pump the cleaning agent amount to be used in smaller and equal amounts and in more than one time.
  • accurate dosing is performed and formation of foam inside the channel is prevented.
  • control unit determines the duration between two working phases of the pump by taking into consideration the duration that elapses for the pumped cleaning agent amount to reach the tub in order to prevent excessive foam formation inside the channel.
  • control unit controls the water supply valve in accordance with the number of pumpings the pump performs and the water settings of the selected washing program in order that the dosing unit operates efficiently.
  • the pump and the water supply valve are enabled to operate in coordination with one another.
  • control unit operates the water supply valve just after one working phase of the pump is completed, thus preventing the total washing duration from being prolonged.
  • control unit controls the water supply valve so as to supply water just before the pump operates and as soon as the pumping operation is finished.
  • the interior of the channel is enabled to be always slippery and thus the cleaning agents are enabled to reach the tub without piling up.
  • control unit controls the water supply valve independently from the pump and the number of pumpings.
  • control unit delivers water by opening the water supply valve when required independently from the pump depending on the data received from the detectors inside the washer.
  • the washer of the present invention can be a washing machine, a laundry washer/dryer or a dishwasher in different embodiments.
  • the washer is controlled by the control unit included therein with the steps of:
  • control unit and the control method used in the washer of the present invention accurate and effective dosing is performed by controlling the dosing unit.
  • the cleaning agents are prevented from foaming as much as possible before reaching the tub wherein the washing process is performed and washing efficiency is prevented from decreasing as a result of the cleaning agent losses due to overflowing.
  • Figure 1 – is the front schematic view of a washer.
  • the washer (1) comprises a tub (2) wherein the washing process is performed, a detergent dispenser (3) having at least one partition (4) wherein the cleaning agents are stored, a channel (5) that is disposed between the tub (2) and the detergent dispenser (3) and that provides liquid transfer, a dosing unit (6) that has at least one pump (7) enabling the cleaning agents to be sucked from the detergent dispenser (3) to be delivered to the tub (2) and at least one water supply valve (8).
  • the washer (1) different types of cleaning agents, for example liquid detergent and softener are stored in different partitions (4) of the detergent dispenser (3) and the dosing unit (6) delivers the cleaning agent to be used in the washing process to the tub (2) by means of the channel (5).
  • different types of cleaning agents for example liquid detergent and softener are stored in different partitions (4) of the detergent dispenser (3) and the dosing unit (6) delivers the cleaning agent to be used in the washing process to the tub (2) by means of the channel (5).
  • the washer (1) of the present invention comprises a control unit (9)
  • the control unit (9) determines the amount of cleaning agent to be used according to the amount determined by the manufacturer depending on the selected program or manually entered by the user. Afterwards, the control unit (9) compares the decided amount with the cleaning agent amount that will form excessive foam inside the channel (5) and/or decides whether or not the pump (7) can pump at its maximum flow rate and controls the pump (7) for mixing the cleaning agent with the wash water according to the result.
  • control unit (9) decides at which flow rate the pump (7) pumps.
  • the control unit (9) changes the flow rate of the pump (7) upon deciding that the cleaning agent to be used in the washing process cannot be dosed controllably while the pump (7) operates at maximum flow rate.
  • control unit (9) enables the cleaning agent to be pumped at a smaller flow rate than the maximum flow rate of the pump (7).
  • the control unit (9) operates the pump (7) at 50 ml/s flow rate thus maintaining precise control.
  • control unit (9) decides after how many pumpings the pump (7) will pump the entire cleaning agent to be used. If the cleaning agent to be used will form excessive foam inside the channel (5) when pumped all at once, then the control unit (9) decreases the amount of cleaning agent to be pumped and increases the number of pumpings.
  • the control unit (9) enables the cleaning agent to be pumped more than once so as to minimize the number of pumpings. Dosing the amount of the cleaning agent to be used by being divided into smaller amounts, excessive foaming of the cleaning agent before mixing with the wash water is prevented and cleaning agent losses are decreased. For example, when the amount of cleaning agent to be used is 100 ml, the pump (7) doses the amounts of 50 ml, 25 ml, 15 ml and 10 ml in that order in 4 allotments. In this embodiment, the number of pumpings the pump (7) performs is minimized so that the washing duration is not prolonged.
  • control unit (9) enables the amount of cleaning agent to be used to be pumped in equal amounts in more than one time. Controlled dosing is provided by dividing the amount of cleaning agent to be used into equal amounts. For example, when the amount of cleaning agent to be used is 100 ml, the pump (7) doses an amount of 10 ml ten times.
  • the control unit (9) regulates the time between two operation phases of the pump (7) with respect to the duration that elapses for the cleaning agent to leave the detergent dispenser (3) and reach the tub (2). For example, if the duration for a certain amount of cleaning agent leaving the detergent dispenser (3) to reach the tub (2) is 10 seconds, the control unit (9) operates the pump (7) every 5 seconds.
  • control unit (9) decides how many times the water supply valve (8) will be opened/closed with respect to the water settings of the selected program and how many times the pump (7) will pump.
  • the water supply valve (8) opening/closing according to the operating schedule of the pump (7) increases washing effectiveness.
  • control unit (9) operates the water supply valve (8) just after the pump (7) completes one operational phase.
  • the phase of cleaning agent intake is prevented from prolonging the total washing duration.
  • the washer (1) comprises the control unit (9) that controls the water supply valve (8) such that the number of times the water supply valve (8) opens/closes is twice the number of pumpings performed by the pump (7).
  • the control unit (9) controls the water supply valve (8) such that the number of times the water supply valve (8) opens/closes is twice the number of pumpings performed by the pump (7).
  • water is flushed before and after the pump (7) operates.
  • the cleaning agent is prevented from leaving residue on the path to the tub (2) and from foaming uncontrollably.
  • the washer (1) comprises the control unit (9) that controls the water supply valve (8) independently from the number of pumping performed by the pump (7).
  • the water supply valve (8) is enabled to supply water.
  • the washer (1) is a washing machine.
  • the washer (1) is a laundry washing and drying machine.
  • the washer (1) is a dishwasher.
  • the washer (1) is controlled by a control method comprising the steps of:
  • the control unit (9) decides on the type of cleaning agent to be used depending on the washing phase, for example detergent or softener, and chooses the amount of cleaning agent to be used depending on the selected program or if the user entered the cleaning agent amount manually, overrides the amount determined by the program and selects the amount entered by the user as the cleaning agent amount to be used in the washing process.
  • the control unit (9) compares the selected amount with the cleaning agent amount that will create excessive foam inside the channel (5) when mixed with water and/or decides whether the pump (7) can be pumped controllably at maximum flow rate, then decides after how many pumpings and at which flow rate the cleaning agent amount to be used will be pumped by the pump (7). Furthermore, the control unit (9) decides how many times the water supply valve (8) will open and close. According to the determined criteria, the dosing unit (6) enables the cleaning agents to be mixed with water.
  • the cleaning agents used in the washing process are prevented from foaming before reaching the tub (2) and hence the washing effectiveness is prevented from decreasing. Besides, cleaning agent losses are minimized.
