Definitions
- the present invention relates to a washing machine and a rinsing control method thereof, and, more particularly, to a washing machine that performs a rinsing operation while rotating a drum at a predetermined RPM and a rinsing control method thereof.
- a washing machine (normally, a drum type washing machine) is a machine, including a water tub to receive water (wash water or rinse water), a cylindrical drum rotatably mounted in the water tub to receive laundry, and a motor to generate a drive force necessary to rotate the drum, which lifts the laundry along the inner wall of the drum and drops the laundry, during the rotation of the drum, to wash the laundry.
- the washing machine performs washing through a series of operations, e.g., a washing operation to separate contaminants from the laundry with water containing detergent (specifically, wash water), a rinsing operation to rinse out bubbles or residual detergent from the laundry with water containing no detergent (specifically, rinse water), and a spin-drying operation to spin-dry the laundry.
- a washing operation to separate contaminants from the laundry with water containing detergent (specifically, wash water)
- a rinsing operation to rinse out bubbles or residual detergent from the laundry with water containing no detergent (specifically, rinse water)
- a spin-drying operation to spin-dry the laundry.
- the drum In the rinsing operation, the drum is stopped, and water draining and intermediate spin-drying processes are performed, after the completion of the washing operation, and then the laundry is brought into contact with water and, at the same time, is lifted and dropped, while alternatively rotating the drum at a velocity (approximately 30 to 50 RPM) to rinse the laundry using a fall of water during the supply of water, thereby rinsing the laundry.
- the rinsing operation is performed through a series of processes, e.g., the stoppage of the drum, the drainage, the spin drying, and the rinsing (the alternating rotation of the drum at a velocity of 30 to 50 RPM).
- the rinsing operation is achieved by repeating the above-mentioned series of processes several times.
- a process to uniformly distribute the laundry W in the drum 12 as shown in FIG. 1 is needed. This is because the drum 12 is rotated at a predetermined RPM (approximately 1000 RPM or more) to spin-dry the laundry at high velocity such that the spin-drying process, performed during the rinsing operation, drains water contained in the laundry W outside by a centrifugal force. If the drum 12 is rotated at the predetermined RPM (approximately 1000 RPM or more) in an unbalanced state in which the laundry W is nonuniformly distributed along the inner wall of the drum 12 as shown in FIG.
- a laundry untangling process is performed to untangle the tangled laundry W through the alternating rotation of the drum 12 before the drum 12 is rotated at the predetermined RPM (approximately 1000 RPM or more) at the time of every spin-drying process in the rinsing operation, which is repeated several times, and the unbalance value is measured.
- the drum 12 is rotated at the predetermined RPM (approximately 1000 RPM or more) to perform the spin-drying process to drain water contained in the laundry W outside by a centrifugal force.
- the laundry untangling process is reperformed to untangle the tangled laundry W through the alternating rotation of the drum 12.
- the laundry untangling process is performed before the drum 12 is rotated at the predetermined RPM (approximately 1000 RPM or more) at the time of every spin-drying process in the rinsing operation, which is repeated several times, and the unbalance value is measured.
- the total rinsing time increases.
- a velocity (alternating rotation of 30 to 50 RPM) of water passing through the laundry W is low in the rinsing process using the fall of water, with the result that the detergent contained in the laundry W does not well dissolve, or the dissolved detergent does not flow out of the laundry W. Consequently, the residual detergent is left in the laundry, whereby the rinsing efficiency is lowered.
- it is required to supply a large amount of water sufficient to fully wet the laundry, which increases the water consumption.
- the present invention provides a rinsing control method of a washing machine including a drum to receive laundry and a motor to rotate the drum, the rinsing control method including rotating the drum to perform spin-drying and decelerating the drum to a predetermined velocity to perform rinsing.
- the rinsing control method further includes performing a laundry untangling process to uniformly distribute the laundry in the drum to perform the spin-drying, and the laundry untangling process is performed only once during the rinsing, which is performed several times.
- the predetermined velocity is a balance maintenance velocity to uniformly distribute the laundry in the drum though the deceleration of the drum after the spin-drying.
- the balance maintenance velocity is a velocity to cling the laundry to the inner wall of the drum while maintaining balance without eccentricity.
- the balance maintenance velocity is approximately 100 RPM or more.
- the performing rinsing includes performing the supply of water, rinsing, and drainage of water for rinsing while rotating the drum at the balance maintenance velocity.
- the performing rinsing includes rotating the drum to perform spin-drying after the drainage and continuously performing the supply of water, rinsing, and drainage of water for the next rinsing while rotating the drum at the balance maintenance velocity.
- the balance maintenance velocity is a velocity in which the water passes through the laundry by a centrifugal force to dissolve detergent contained in the laundry.
- the balance maintenance velocity is a velocity in which the water passes through the laundry by a centrifugal force to immediately discharge detergent remaining in the laundry.
- the present invention provides a rinsing control method of a washing machine including a drum to receive laundry and a motor to rotate the drum, the rinsing control method including rotating the drum to perform spin-drying and decelerating the drum to a predetermined velocity to supply water.
- the present invention provides a washing machine including a drum to receive laundry, a motor to rotate the drum, and a control unit to control the velocity of the drum such that the drum is rotated to perform spin-drying and is decelerated to a predetermined velocity to perform rinsing.
- control unit controls a laundry untangling process to be performed to uniformly distribute the laundry in the drum to perform the spin-drying, the laundry untangling process being performed only once during the rinsing, which is performed several times.
- the washing machine further includes a water supply unit, and the control unit controls the motor to rotate the drum at the balance maintenance velocity and the water supply unit to supply water, during the rotation of the drum, to perform the rinsing.
- the washing machine further includes a drainage unit, and the control unit controls the drainage unit to drain the water during the rotation of the drum.

- a heater receiving part 17 is formed at the bottom of the water tub 11 such that the heater receiving part 17 protrudes downward to receive the wash heater 16 and, at the same time, collect a predetermined amount of water. This is because the wash heater 16 can be immersed in the water collected in the heater receiving part 17, and the drum can be rotated without the interference with the wash heater 16 since the wash heater 16 is received in the heater receiving part 17.
- the machine body 10 is provided at the front thereof with an inlet 10b which corresponds to an inlet 12b of the drum 12 and an inlet 11b of the water tub 11 such that laundry W is put in or taken out from the drum 12 through the inlet 10b.

Consequently, water is supplied into the water tub 11 via the detergent supply unit 19 such that detergent is supplied into the water tub 11 together with the water.
- the washing machine further includes a drainage unit 30 to drain the water in the water tub 11 and a circulation unit 40 to supply the water in the water tub 11 into the drum 12.
- the drainage unit 30 includes a first drainage pipe 31 connected to a drainage port 17a formed at the heater receiving part 17 in the bottom of the water tub 11 to guide the water in the water tub 11 outside, a drainage pump 32 mounted on the first drainage pipe 31, and a second drainage pipe 33 connected to the outlet of the drainage pump 32.
- the circulation unit 40 includes a flow channel switching valve 41 mounted on the second drainage pipe 33, a circulation pipe 42 extending from the flow channel switching valve 41 to the inlet 12b of the drum 12, and a spray nozzle 43 mounted at the outlet of the circulation pipe 42.
- the flow channel switching valve 41 serves to switch flow channels such that the water from the outlet of the drainage pump 32 is drained outside or flows to the circulation pipe 42.
- the flow channel switching valve 41 may be an electric three-way valve.
- the spray nozzle 43 is mounted adjacent to the inlet 12b of the drum 12 such that the spray nozzle 43 sprays water into the drum 12 through the inlet 12b of the drum 12.
- FIG. 4 is a rinsing control block diagram of the washing machine according to the embodiment of the present invention.
- the washing machine further includes an input unit 50, a water level detection unit 52, a temperature detection unit 54, a control unit 56, a drive unit 58, a velocity detection unit 60, and a current detection unit 62.
- the input unit 50 inputs operation information, such as a washing course, a washing temperature, spin-drying RPM, and the addition of rinsing, which are selected by a user, to the control unit 56.
- operation information such as a washing course, a washing temperature, spin-drying RPM, and the addition of rinsing, which are selected by a user.
- the water level detection unit 52 detects the water level of water supplied into the water tub 11
- the temperature detection unit 54 detects the temperature of water supplied into the water tub 11.
- the control unit 56 is a microprocessor to control the overall operation of the washing machine, such as washing, rinsing, and spin-drying, based on the operation information inputted from the input unit 50.
- the control unit 56 stores the amount of rinse water, motor RPM and operation rate (motor on-off time), and rinsing time set according to the amount of load (the weight of laundry) in the selected washing course.
- the control unit 56 controls the rinsing operation, including the supply of water, rinsing, and drainage of water, to be performed, while continuously rotating the drum 12 at a velocity (100 to 150 RPM) to maintain a balanced state without stopping the motor 12 after spin-drying, such that the water passes through the laundry W at high velocity and is drained.
- control unit 56 controls intermediate spin-drying (initial spin-drying) to be performed after the drainage of wash water (detergent and water) to perform rinsing after the washing.
- intermediate spin-drying initial spin-drying
- a laundry untangling process is performed to uniformly distribute the laundry W in the drum 12 such that the laundry W is maintained in a balanced state, and then the unbalance value is measured, which is necessary to smoothly spin-dry the laundry W.
- the control unit 45 controls the drum 12 to be rotated at a predetermined RPM (approximately 800 to 1000 RPM) such that spin-drying is performed.
- the control unit 56 After the completion of the spin-drying, the control unit 56 lowers the velocity of the drum 12 to a velocity to maintain the balanced state, e.g., approximately 100 to 150 RPM, without stopping the drum 12, and control the rinsing operation, including the supply of water, rinsing, and drainage of water, to be performed while continuously rotating the drum 12. At this time, the balanced state is continuously maintained, and therefore, the control unit 56 controls spin-drying to be immediately performed without the execution of a laundry untangling process.
- the balanced state e.g., approximately 100 to 150 RPM
- control unit 56 omits a laundry untangling process and an unbalanced state measuring process at the time of every spin-drying. As a result, the total rinsing time is reduced. Also, when the control unit 56 controls further rinsing to be performed within the reduced rinsing time, it is possible to perform much more rinsing within rinsing time necessary for the related art washing machine, thereby improving rinsing efficiency.
- control unit 56 controls the operations of the motor 15, the water supply unit 20 and the drainage unit 30 such that a rinsing operation, including the supply of water, rinsing, and drainage of water, is performed, while the drum 12 is rotated at a velocity (approximately 100 to 150 RPM) to maintain the balanced state in one direction, with the result that water (specifically, rinse water) passes through the laundry W at high velocity by a centrifugal force to dissolve the detergent contained in the laundry W, and the water having passed through the laundry W is immediately drained to fully remove the residual detergent from the laundry W.
- a rinsing operation including the supply of water, rinsing, and drainage of water
- the drive unit 58 drives the motor 15, the wash heater 16, the water supply valve 24, the drainage pump 32, and the flow channel switching valve 41 according to a drive control signal of the control unit 56.
- the velocity detection unit 60 inputs a motor velocity signal corresponding to the rotation velocity of the drum 12 to the control unit 56 to detect whether the velocity of the drum 12 has lowered due to the velocity reduction of the motor 15.
- the current detection unit 62 inputs a motor current signal corresponding to the rotation velocity of the drum 12 to the control unit 56 to measure an unbalanced state.
- FIGS. 5A and 5B are flow charts illustrating a rinsing control method of the washing machine according to the embodiment of the present invention.
- a washing operation to perform washing with water and detergent is identical to the operation of a general washing machine, and therefore, a detailed description thereof will not be given.
- the operation information selected by the user is inputted to the control unit 56 through the input unit 54.
- control unit 56 determines whether the power is on so as to perform a rinsing operation based on the operation information inputted from the input unit 54 (100).
- control unit 56 detects the amount of load (the weight of laundry) put in the drum 12, and sets the minimum amount of water, motor operation rate (motor on-off time), and washing and rinsing time for washing and rinsing based on the detected amount of load.
- control unit 56 controls a washing operation to be performed such that water (specifically, wash water) necessary to wash the laundry W is supplied into the water tub 11 together with detergent to supply water having an amount set based on the amount of load, the washing is performed by a frictional force with the drum 12 and a falling force of the laundry W while the wash water (water and detergent) is well absorbed into the laundry, by the rotation of the drum 12 and the operation of the circulation unit 40 (102).
- water specifically, wash water
- detergent to supply water having an amount set based on the amount of load
- control unit 56 determines whether washing time set based on the amount of load has elapsed (104). When the washing time has not elapsed, the procedure returns to Operation 102 to continue the washing operation to perform washing with wash water.
- the control unit 56 drains the wash water through the drainage unit 30 (106), and controls a laundry untangling process to be performed in which the motor 15 is controlled through the drive unit 58 to smoothly perform spin-drying, such that the drum 15 is alternately rotated, thereby untangling the tangled laundry W (108).
- the laundry untangling process is a process in which an operation to stop the drum for a predetermined time (approximately 5 seconds) after the motor 26 is rotated in the forward direction at a predetermined RPM (e.g. approximately 40 to 45 RPM) for a predetermined time (e.g. approximately 5 seconds) and an operation to stop the drum for a predetermined time (e.g. approximately 5 seconds) after the motor 26 is rotated in the reverse direction at a predetermined RPM (e.g. approximately 40 to 45 RPM) for a predetermined time (e.g. approximately 5 seconds) are repeatedly performed in an alternating fashion.
- the drum 12 is alternately rotated to untangle the laundry W, with the result that the laundry W is uniformly distributed in the drum 12 to maintain the balance state, as shown in FIG. 1 .
- control unit 56 measures an unbalance value through the current detection unit 62 from a predetermined unbalance measurement velocity before the rotation of the drum 12 at a predetermined RPM (e.g. approximately 800 to 1000 RPM) (110), and determines whether the measured unbalance value is equal to or less than a predetermined allowable value (112).
- a predetermined RPM e.g. approximately 800 to 1000 RPM
- a method of measuring the unbalance value by the control unit 56 is to estimate the size of unbalance in the drum 12 utilizing weight information of the laundry W and a control variable, such as a velocity ripple or a current ripple.
- a control variable such as a velocity ripple or a current ripple.
- control unit 56 determines that the state of the laundry is the unbalanced state and controls the operation of the motor 15 through the drive unit 58 such that the drum 12 is stopped (113). After that, the procedure returns to Operation 108 to reperform the laundry untangling process to maintain the balanced state.
- control unit 56 determines that the state of the laundry is the balanced state and performs a spin-drying process in which the operation of the motor 15 is controlled through the drive unit 58, such that the drum 12 is rotated at the predetermined RPM (approximately 800 to 1000 RPM), to drain the water contained in the laundry W outside by a centrifugal force (114).
- the control unit 56 determines whether the spin-drying has been completed (116). When the spin-drying has not been completed, the procedure returns to Operation 114 to continue the spin-drying. On the other hand, when the spin-drying has been completed, the control unit 56 reduces the velocity of the motor 15 through the drive unit 58 to reduce the rotation velocity of the drum 12 to a velocity (approximately 100 to 150 RPM) to maintain the balanced state without stopping the drum 12 (118).
- the velocity detection unit 60 detects a motor velocity signal corresponding to the rotation velocity of the drum 12 and inputs the detected motor velocity signal to the control unit 56.
- the control unit 56 determines whether the rotation velocity of the drum 12, detected by the velocity detection unit 60, is a predetermined balance maintenance velocity (a velocity in which the laundry is maintained in the balanced state while remains clung to the inner wall of the drum; approximately 100 to 150 RPM) (120).
- a predetermined balance maintenance velocity a velocity in which the laundry is maintained in the balanced state while remains clung to the inner wall of the drum; approximately 100 to 150 RPM
- the control unit reduces the velocity of the motor 15 and thus the rotation velocity of the drum 12.
- control unit 56 When it is determined at Operation 120 that the rotation velocity of the drum 12 is the balance maintenance velocity, the control unit 56 performs rinsing operation,.
- the control unit 56 controls the drum 12 to be rotated in one direction while maintaining the rotation velocity of the drum 12 at the balance maintenance velocity (approximately 100 to 150 RPM), such that the laundry W remains clung to the inner wall of the drum 12, to reduce rinsing time and improve rinsing efficiency.
- the control unit 56 controls the water supply unit 20 to supply rinse water.
- the water supply valve 24 is opened, and therefore, water (rinse water) is supplied into the water tub 11 through the supply water pipes 21, 22, and 23 (122).
- the water level detection unit 52 detects the water level of the rinse water supplied into the water tub 11, and the control unit 56 determines whether the detected water level is a predetermined water level (124).
- the predetermined water level may be set at various different levels.
- control unit 56 controls water to be continuously supplied into the water tub 11 until the water level of the rinse water reaches the predetermined water level.
- control unit 56 controls the control valve 24 to be closed such that the supply of water is interrupted (126).
- control unit 56 controls the rinsing operation to be performed in which the drum is rotated in one direction while the rotation velocity of the drum 12 is continuously maintained at the balance maintenance velocity (e.g. approximately 100 to 150 RPM) such that the laundry W remains clung to the inner wall of the drum 12, and the rinse water is supplied into the drum 12 through the circulation unit 40, to rinse the laundry W with the rinse water supplied into the water tub 11.
- the balance maintenance velocity e.g. approximately 100 to 150 RPM
- Water is supplied during the rotation of the drum in one direction at the velocity (approximately 100 to 150 RPM) at which the balanced state is maintained while the laundry W remains clung to the inner wall of the drum 12.
- the drum 12 is continuously rotated in one direction to continue the rinsing, with the result that the rinse water passes through the laundry at high velocity.
- w angular velocity
- control unit 56 determines whether predetermined rinsing time has elapsed (130). When the rinsing time has not lapsed, the procedure returns to Operation 128 to continue the rinsing operation while maintaining the rotation velocity of the drum 12.
- control unit 56 controls the drainage pump 32 and the flow channel switching valve 41 to drain the rinse water.
- control unit 56 controls the drum 12 to be rotated in one direction while the rotation velocity of the drum 12 is maintained at the balance maintenance velocity (e.g. approximately 100 to 150 RPM) such that the laundry W remains clung to the inner wall of the drum 12 (132).
- balance maintenance velocity e.g. approximately 100 to 150 RPM
- control unit 56 raises the rotation velocity of the drum 12 according to the operation of the motor 15 such that the drum is rotated at a predetermined number of rotations (approximately 1000 RPM) to perform intermediate spin-drying (134).
- the present invention omits a laundry untangling process, which was performed at the time of every spin-drying to smoothly perform spin-drying after the drainage of the rinse water, and accelerates the rotation velocity of the drum 12 to the predetermined number of rotations (approximately 1000 RPM) such that the spin-drying is immediately performed.
- the laundry untangling process is performed at the time of every spin-drying to smoothly achieve spin-drying after the drainage in the related art.
- the rinsing operation including the supply of water, rinsing, and drainage of water, is performed while the drum is continuously rotated at a velocity (100 to 150 RPM) to maintain the balanced state without stopping the drum 12, as shown in FIG. 6 , after the initial spin-drying (intermediate spin-drying after washing). Consequently, the laundry untangling process to smoothly achieve spin-drying may only be performed once (even though the present invention does not limit the laundry untangling process to be performed only once) after the initial spin-drying (intermediate spin-drying after washing).
- the laundry untangling process may be omitted at subsequent spin-drying processes, the laundry W is continuously maintained in the balanced state in which the laundry W is uniformly distributed along the inner wall of the drum 12. Consequently, the laundry untangling process and the process to measure the unbalanced state after the laundry untangling process may be omitted, and therefore, the total rinsing time is reduced.
- the control unit 56 determines whether the rinsing operation is the final rinsing (136). When the rinsing operation is not the final rinsing, the procedure returns to Operation 114 to continuously perform the supply of water, rinsing, and drainage of water for the next rinsing while rotating the drum 12 at a velocity (100 to 150 RPM) to maintain the balanced state without stopping the drum 12.
- the rinsing operation is the final rinsing
- the spin-drying is performed at a predetermined final spin-drying RPM (approximately 1100 RPM or more) (138), and then the drum 12 is stopped to end the operation.
- the washing machine and the rinsing control method thereof have the effect of performing a rinsing operation, including the supply of water, rinsing, and drainage of water, while rotating the drum at a predetermined RPM, such that water can pass through laundry at high velocity and be drained by a centrifugal force, thereby improving rinsing efficiency.
- the washing machine and the rinsing control method thereof according to the present invention have the effect of performing a rinsing operation at a predetermined RPM to maintain a balanced state without stopping the drum after spin-drying, thereby omitting a laundry untangling process performed at the time of every spin-drying, and therefore, reducing the total rinsing time. Furthermore, the washing machine and the rinsing control method thereof according to the present invention have the effect of performing further rinsing within reduced rinsing time, thereby improving rinsing efficiency.
