Abstract
Description
Technical Field
[0001] This disclosure relates to a laundry treatment apparatus and a laundry treatment method. Background Technology
[0002] Typically, a laundry treatment device is a device that treats clothes by applying physical and chemical actions to them.
[0003] A laundry processing device may include a tub housed in a suspended manner inside a cabinet and a drum configured to rotate within the tub while clothes (or garments) are housed therein.
[0004] The drum can rotate to remove contaminants from clothes. Clothes inside the drum can be spun or dropped as the drum rotates.
[0005] Typical laundry processes include washing, rinsing, and spin-drying cycles.
[0006] To improve the washing performance of clothes, the rotation of the drum can be controlled to make the drum rotate at high speed or have various movements, and a heating unit can be used to increase the temperature of the washing water.
[0007] However, as the mechanical forces transmitted to the clothes increase to improve washing performance, microplastics separate from the clothes, which leads to the disadvantage of an increased amount of separated microplastics. When the amount of microplastics increases, there is a problem of increased environmental pollution caused by microplastics being included in the discharged wash water.
[0008] Korean Patent Publication No. 2023-0132990 (which is Prior Art Document 1) discloses a laundry treatment method for effectively washing clothes that require delicate handling, but does not disclose a technology for reducing the amount of microplastics generated.
[0009] Korean Patent Publication No. 2023-0059161 (which is Prior Art Document 2) discloses a technique for effectively separating microplastic fibers separated from clothing from washing water, but does not disclose a technique for reducing the amount of microplastics generated. Summary of the Invention
[0010] Technical issues
[0011] One embodiment provides a laundry treatment apparatus and a laundry treatment method that can reduce the amount of microplastics generated during the laundry treatment process.
[0012] Alternatively or additionally, one embodiment provides a laundry processing apparatus and a laundry processing method that can reduce the heat generated by a heating unit operating during the laundry processing.
[0013] Technical solution
[0014] According to one aspect, a laundry treatment method may include a washing program, a rinsing program, and a spin-drying program.
[0015] The washing program may include a first motion period and a second motion period following the first motion period.
[0016] During the first movement period, the roller used to hold the clothes can run in a first movement and then stop for a first stopping time.
[0017] During the second movement period, the roller may operate in a second movement and then stop for a second stopping time.
[0018] After the first exercise period ends, the second exercise period can be executed repeatedly, and then the first exercise period can be executed again.
[0019] During the first motion period, the first motion is performed for the first time, and the first stop time may be longer than the first time.
[0020] The second stop time can be longer than the first time.
[0021] During the first time period, the roller can rotate multiple times in one direction.
[0022] During the first motion period, the roller can rotate multiple times in one direction to operate during the first motion.
[0023] During the second motion period, the roller can repeatedly perform forward and reverse rotations to operate in the second motion.
[0024] During the second motion period, the second motion is performed for a fourth time, and the second stop time may be longer than the fourth time.
[0025] The rinsing process may include a third motion phase. This third motion phase may be performed multiple times during the rinsing process.
[0026] During the third motion period, the roller may operate in the second motion and then stop for a third stopping time.
[0027] The third stopping time can be equal to or less than the second stopping time. The third stopping time can be equal to or less than the first stopping time.
[0028] During the third motion period, the roller can repeatedly perform forward and reverse rotations to operate in the second motion.
[0029] During the third motion period, the second motion is performed for a sixth time, and the third stop time may be longer than the sixth time.
[0030] The operating rate in the washing program is a first operating rate, and the operating rate in the rinsing program is a second operating rate, wherein the second operating rate may be greater than the first operating rate.
[0031] The operating rate (%) can be calculated by (running time of the drive used to rotate the drum / total time in one cycle) x 100.
[0032] A period is the time from the start time of the first movement period to the end time of the last second movement period among a plurality of second movement periods.
[0033] According to another aspect, a laundry processing device may include: a cabinet; a tub housed in the cabinet and storing washing water; a drum positioned in the tub and holding clothes; a drive that rotates the drum; and a controller that controls the drive.
[0034] The controller can be configured to execute washing and rinsing programs for washing the garments.
[0035] The washing program may include a first exercise period and a second exercise period following the first exercise period.
[0036] During the first movement period, the roller containing the clothing may operate in a first movement and then stop for a first stopping time. During the second movement period, the roller may operate in a second movement and then stop for a second stopping time.
[0037] The rinsing process may include a third motion period. During the third motion period, the drum may operate in the second motion and then stop for a third stop time.
[0038] During the first motion period, the first motion is executed for a first time, and the first stop time and the second stop time may be greater than the first time.
[0039] After the first exercise period ends, the second exercise period can be executed repeatedly, and then the first exercise period can be executed again.
[0040] According to another approach, a laundry treatment method may include a washing procedure and a rinsing procedure.
[0041] In the washing process, the movement of the drum containing the clothes may consist only of the first movement and the second movement, and in the rinsing process, the movement of the drum may consist only of the second movement.
[0042] The first motion is the motion of the roller rotating multiple times, and the second motion can be the motion of the roller repeatedly rotating in a forward or reverse direction within a range of half a turn or less.
[0043] Beneficial effects
[0044] According to one embodiment, the advantage is that, while ensuring washing performance, the amount of microplastics generated during the garment processing can be reduced.
[0045] According to one embodiment, the advantage is that the heat generated by the heating unit operating during the washing process can be reduced. Attached Figure Description

Figure 2 This is a front view showing the internal structure of the laundry treatment apparatus according to this embodiment. Figure 3 This is a longitudinal cross-sectional view showing the internal structure of the laundry processing apparatus of this embodiment. Figure 4 This is a control block diagram of the laundry processing apparatus according to this embodiment.
[0058] Figure 2 and Figure 3 This example illustrates a situation where a portion of the cabinet has been removed.
[0059] Reference Figures 1 to 4 The laundry processing apparatus 1 of this embodiment may include a cabinet 10 forming the appearance.
[0060] The cabinet 10 can be formed from a single component or from a combination of multiple components.
[0061] The laundry treatment device 1 may also include a tub 20 disposed inside the cabinet 10. Washing water can be contained in the tub 20.
[0062] The washing apparatus 1 may also include a drum 30 disposed inside the tub 20 and for holding clothes. The drum 30 may be rotated by a drive 40.
[0063] The washing process method of this embodiment can be applied, for example, to a situation where the rotation center C of the drum 30 is horizontally positioned, but is not limited thereto. Even when the rotation center C of the drum 30 is inclined relative to the horizontal plane, the washing process method of this embodiment can be applied in the same way or in a modified manner.
[0064] If the washing process method of this embodiment is applied in a modified manner, the length of the drum's rotation time or the length of its stop time in the microplastic reduction process, which will be described later, can be changed, or the number of times the drum rotates can be altered.
[0065] The cabinet 10 includes an inlet for introducing clothing, which can be opened and closed via a door 11. Each of the tub 20 and the roller 30 may include an opening that communicates with the inlet. When the door 11 is opened, clothing can be contained inside the roller 30 through the inlet and the opening.
[0066] The laundry processing device 1 may also include a detergent dispenser 14 containing detergent. The laundry processing device 1 may also include a control panel 13.
[0067] The control panel 13 may include an input section 71 for entering various commands. Through the input section 71, various operating commands such as selecting the washing process, setting the running time for each program, and scheduling can be entered.
[0068] The washing process can include various processes such as standard processes, and in particular, in this embodiment, it can include a microplastic reduction process.
[0069] The control panel 13 may include a display 72 for displaying the operating status of the washing machine 1. The input unit 71 and the display 72 may be separate components, and the display 72 may also be used as the input unit 71.
[0070] The washing processing apparatus 1 may also include a heating unit 73. The heating unit 73 can heat the washing water. During the microplastic reduction process, the heating unit 73 can heat the washing water so that the temperature of the washing water reaches a temperature within a reference temperature range during the washing program.
[0071] The upper limit of the reference temperature range can be 40°C or a temperature similar to 40°C. The lower limit of the reference temperature range can be 30°C or a temperature similar to 30°C.
[0072] Washing performance can be improved if the temperature of the washing water is higher than the upper limit temperature, but there is a possibility that the amount of microplastics may increase.
[0073] The pollutants (sebum, sweat, blood, etc.) that adhere to clothing are composed of protein components, and washing efficiency can be improved when the temperature of the washing water is within the reference temperature range.
[0074] Therefore, if the heating unit 73 is controlled so that the temperature of the washing water is within the reference temperature range, the advantages are that the formation of microplastics can be reduced and the separation performance of pollutants can be improved, while the power consumption can be reduced by reducing the heat of the heating unit 73.
[0075] The laundry treatment device 1 may also include a water supply valve 75 for regulating the inflow of washing water from an external water source.
[0076] The system senses the load of the laundry during the washing process and can determine the water supply corresponding to the sensed load. The water supply valve 75 can be controlled to supply washing water at the determined water supply volume.
[0077] The laundry treatment device 1 may also include a drain device 50 for draining the washing water from the tub 20.
[0078] The washing treatment device 1 may also include a damping unit 60 connected to the lower part of the tub 20 to reduce vibration.
[0079] The washing processing device 1 may also include a controller 70. The controller 70 can control the drive 40. The control mode and running time of the drive 40 can be determined for each washing process.
[0080] The controller 70 can control only the driver 40, or it can control other components besides the driver 40.
[0081] The laundry treatment method will be described below.
[0082] Figure 5 This is a flowchart illustrating a laundry treatment method according to this embodiment. Figure 6 This is a flowchart illustrating the washing procedure in the microplastic reduction process.
[0083] Figure 7 This is a view illustrating the motion in a washing procedure that is used to explain the microplastic reduction process. Figure 8 This is a view used to illustrate the movement of clothing during a washing process based on the microplastic reduction process.
[0084] Figure 9 This is a view used to illustrate the motion in the rinsing process during the microplastic reduction process.
[0085] Reference Figures 5 to 9 The laundry treatment method of this embodiment may include a washing program, a rinsing program, and a spin-drying program.
[0086] Typically, the washing process can include a washing program, a rinsing program, and a spin-drying program.
[0087] The microplastic reduction process of this embodiment may also include a washing program, a rinsing program, and a dehydration program.
[0088] The microplastic reduction process can be selected, and a start command can be entered through the input unit 71.
[0089] When a start command is input, the garment load sensing step (S1) can be executed. During the garment load sensing step, the driver 40 can be operated, causing the roller 30 to rotate.
[0090] Since methods for sensing clothing load can be implemented using known techniques, their detailed description will be omitted.
[0091] When the clothing load sensing step is completed, the water supply step (S2) can be executed. When the clothing load is sensed in the clothing load sensing step, the water supply volume can be determined according to the sensed clothing load. In the water supply step, the water supply valve 75 can be controlled to supply washing water at the determined water supply volume.
[0092] Once the water supply step is completed, the step of heating the washing water (S3) can be performed. As described above, the heating unit 73 can operate to ensure that the temperature of the washing water is within a reference temperature range, thereby improving the separation performance of contaminants.
[0093] The washing program (S4) can be executed after the washing water heating step is completed or during the washing water heating step. Alternatively, the washing program of this embodiment may include a water supply step and a heating step.
[0094] Microplastic reduction is a process used to reduce the release of microplastics by minimizing damage to clothing by reducing the mechanical forces transmitted to it in a laundry treatment unit.
[0095] In particular, considering the special materials (such as polyester fibers) from which a large number of microplastics are separated, the microplastic reduction process is a process designed to minimize the transfer forces during washing and rinsing while maintaining the washing level.
[0096] The mechanical action within a laundry treatment unit primarily involves three types of forces: centrifugal force transmitted to the fabric as the drum rotates, frictional force (with the drum wall), and gravity (falling impact), as well as frictional and shear forces (between fabrics) generated as the fabric moves.
[0097] When the roller 30 runs at a constant speed under gravitational acceleration without changing direction, forces accumulate on the same load portion within the roller 30, causing interference and friction between the fabrics, thus maximizing damage. As the mechanical force transmitted to the fabric increases, both hydrophilic and hydrophobic fibers undergo fibrillation as fibers break at the surface. When the fibers raised to the surface are continuously subjected to mechanical forces in this manner, they are separated and become microfibers.
[0098] Therefore, in this embodiment, the microplastic reduction process may include performing washing motions by minimizing the friction and gravity transmitted to the fabric.
[0099] In order to apply impact and shear forces while minimizing the friction transmitted to the fabric, a motion in which the fabric moves in continuous reverse order and a physical space in which the fabric in the rollers is fixed can move independently are required.
[0100] In the microplastic reduction process of this embodiment, the impact and shear forces transmitted to the fabric are distributed to a portion of the fabric by using a movement that can reverse the position of the garment, thereby minimizing damage to the garment.
[0101] Furthermore, in the case of the microplastic reduction process of this embodiment, the use of motion that can ensure washing performance by using falling impact force is addressed in the case of reduced washing efficiency as the physical force transmitted to the fabric is minimized.
[0102] In the washing program of this embodiment, cleaning power can be ensured by the combination of the first and second movements of the drum and the operating rate, which will be described later.
[0103] The first motion is the motion in which the drum rotates multiple times at a speed of 1G or less, and can be the motion that generates the transmission force for washing by providing a constant downward force to the clothes.
[0104] The second motion can be a motion in which the drum rotates repeatedly in a forward or reverse direction at a speed of 1G or less within a range of half a circle or less. This second motion can change the state of the garment (clothes tumbling) and can change the part in contact with the washing liquid.
[0105] When considering material properties, fibers made of special materials that separate a large number of microplastics have lower hygroscopicity than materials such as cotton, and therefore have fewer functional groups through which water can be adsorbed into the fibers.
[0106] Therefore, in the rinsing process, the washing liquid can be easily separated even under low mechanical force, so that rinsing can be carried out even under conditions with lower mechanical force compared to cotton fibers (e.g., only the second motion).
[0107] For example, in the microplastic reduction process of this embodiment, the washing procedure may include a first motion period and a second motion period following the first motion period.
[0108] Reference Figure 7 The first motion period may include a first rotation period in which the roller 30 (or the driver) rotates. The first motion period may also include a first stop period in which the roller 30 (or the driver) stops.
[0109] During the first rotation period, the roller 30 can operate in a first motion (S41). The first motion of the roller 30 is... Figure 8 As shown in (A).
[0110] When the roller 30 is in its first movement, the garment L rotates along the roller 30 and can fall from a predetermined height (garment falling movement) (see arrow A). That is, the garment L is not held attached to the roller 30, but can fall during the rotation of the roller 30.
[0111] For example, roller 30 can rotate in one direction at a first rpm for a first time. The first rpm can be, for example, 46 rpm, but it is variable.
[0112] After the roller 30 rotates for a first time, the roller 30 can be stopped for a second time. The first time is the duration of the first rotation period, and the second time is the duration of the first stop period. The second time can be referred to as the first stop time.
[0113] The sum of the first time point and the second time point is the total time of the first motion period.
[0114] The second time can be longer than the first time.
[0115] For example, the first time interval could be A seconds, and the second time interval could be 5A seconds. Alternatively, the first time interval could be 5 seconds, and the second time interval could be 25 seconds.
[0116] However, this disclosure is not limited thereto; the length of the first time and the length of the second time may vary, and the ratio between the first time and the second time in the first rotation period may also vary.
[0117] Alternatively, during the first rotation period, the roller 30 may rotate P times. After the roller 30 rotates P times, the roller 30 may stop for a second time.
[0118] In this embodiment, the first motion period can be executed L times. L can be a natural number of 1 or greater. For example, after executing the first motion period once, the second motion period can be executed. Of course, the second motion period can also be executed after executing the first motion period multiple times.
[0119] Reference Figure 7 The second motion period may include a second rotation period in which the roller 30 (or the drive) rotates. The second motion period may include a second stop period in which the roller 30 (or the drive) stops.
[0120] During the second rotation period, roller 30 can operate in a second motion (S42). The second motion of roller 30 in... Figure 8As shown in (B). When the roller 30 is running in the second motion, the garment L can be tumbled inside the roller 30 (garment tumbling motion). For example, the garment can rotate along the roller 30 and then tumble at a specific location (see arrows B and C).
[0121] For example, roller 30 can rotate in one direction (forward rotation) and then in the opposite direction (reverse rotation). During the second rotation period, the forward and reverse rotations of roller 30 can be repeated. As described above, roller 30 can rotate within a range of half a turn or less.
[0122] During the forward or reverse rotation of the roller 30, the roller 30 can rotate at a second rpm.
[0123] During the second rotation period, roller 30 can rotate N times. When calculating the number of rotations of roller 30, forward rotation can be considered as the first rotation, and reverse rotation can be considered as the second rotation. N can be, for example, 4, but is variable.
[0124] After the roller 30 rotates N times, the roller 30 can stop for a third time. This third time is the duration of the second stopping period. The third time can be referred to as the second stopping time.
[0125] The third time can be longer than the time when the drum rotates N times.
[0126] The third time can be the same as or different from the second time. The third time can be, for example, 25 seconds, but it is variable.
[0127] As another example, the second rotation period can be executed up to a fourth time. In this case, the fourth time can be shorter than the third time. The fourth time can be shorter than the first time. The lengths of both the fourth and third times can be varied, and the ratio between the fourth and third times in the second motion period can also be changed.
[0128] In this embodiment, the second motion period can be executed B times. B can be a natural number greater than 2.
[0129] The number of times the second exercise period is executed can be greater than the number of times the first exercise period is executed. For example, the first exercise period can be executed once, and the second exercise period can be executed twice, but this is variable.
[0130] In this embodiment, the time period from the start time of the first movement period to the last of the plurality of second movement periods can be a cycle. This cycle can be repeated during the washing program.
[0131] In the washing program, the operating rate in each program can be maintained at a first operating rate or maintained within a first range. The first operating rate can be included within the first range.
[0132] In this instruction manual, (Actual running time of the drive used to rotate the drum / Total time in one cycle) x 100 The run rate (%) can be calculated as described above.
[0133] The actual running time of the drive can be the rotation time of the roller.
[0134] In each program, the rotation direction of the roller 30 during the first movement can change. For example, during the first movement in the first program, the roller 30 rotates in the forward direction; during the first movement in the second program, the roller 30 rotates in the reverse direction; and during the first movement in the third program, the roller 30 can rotate in the forward direction.
[0135] If the drum 30 rotates in the same direction for each program, the clothes fall in a single direction, increasing the washing power. However, this can lead to increased damage to the clothes due to the accumulation of force on a portion of the garment. In this embodiment, however, when the rotation direction of the drum 30 is changed for each program, the location of the force accumulation is altered by tumbling the clothes, thereby reducing damage to the garments.
[0136] Furthermore, during the first motion phase, the rotation direction of the roller 30 remains unchanged, causing force to accumulate on a portion of the garment. However, during the second motion phase, the force transmitted to the garment can be distributed through the garment's tumbling motion, thereby reducing damage to the garment.
[0137] While the washing program is being executed, it can be determined whether the conditions for ending the washing program are met (S5).
[0138] The conditions for ending the washing program can be, for example, when the program's progress time reaches a first reference time. The first reference time can vary depending on the sensed load of laundry.
[0139] Alternatively, the washing program may end when the cumulative number of cycles reaches a reference number. Alternatively, the washing program may end when the cumulative number of cycles in the first motion period reaches a reference number or the cumulative number of cycles in the second motion period reaches a reference number.
[0140] When the conditions for ending the washing program are met, the washing water used in the washing program can be dehydrated (washing and dehydration) (S6).
[0141] When washing and dehydration are complete, a rinsing procedure (S7) can be performed. Rinse water supply can also be carried out during the rinsing procedure.
[0142] In the microplastic reduction process of this embodiment, the rinsing cycle may include a third motion period.
[0143] The third exercise period may be the same as or different from the second exercise period in the washing program.
[0144] Reference Figure 9 The third motion period may include a third rotation period in which the roller 30 (or the driver) rotates and a third stop period in which the roller 30 (or the driver) stops.
[0145] During the third rotation period, the roller 30 can operate in a second motion. Through the second motion of the roller 30, the clothes can be tumbled inside the roller 30 (clothes tumbling motion).
[0146] For example, roller 30 can rotate in one direction (forward rotation) and then in the opposite direction (reverse rotation). During the third rotation period, the forward and reverse rotations of roller 30 can be repeated.
[0147] The motion of the roller 30 is the same in each of the second and third rotation periods, and the number of forward and reverse rotations of the roller 30 may be the same or different.
[0148] During the third rotation period, roller 30 can rotate M times. When calculating the number of rotations of roller 30, forward rotation can be considered as the first rotation, and reverse rotation can be considered as the second rotation. M can be the same as or different from N.
[0149] After the roller 30 rotates M times, the roller 30 can be stopped for a fifth time period. The fifth time period is the duration of the third stop period. The fifth time period can be referred to as the third stop time.
[0150] The fifth time can be longer than the time when the drum rotates M times.
[0151] The fifth time can be the same as or different from the third time. When the fifth time is different from the third time, the fifth time can be shorter than the third time.
[0152] The fifth time interval could be, for example, 20 seconds, but it is variable.
[0153] As another example, a third rotation period can be performed up to a sixth time. In this case, the sixth time can be less than the fifth time. The sixth time can be the same as or different from the fourth time.
[0154] The lengths of the fifth and sixth times can be changed, and the ratio between the fifth and sixth times in the third movement period can also be changed.
[0155] In this embodiment, the third motion phase can be repeatedly executed during the rinsing process until the rinsing process ends.
[0156] In the rinsing process, the operating rate can be maintained at a second operating rate or maintained within a second range. The second operating rate can be included within the second range.
[0157] The second run rate can be greater than the first run rate. The first run rate and the second run rate can be 20% or less.
[0158] While performing the rinsing procedure, it can be determined whether the termination condition of the rinsing procedure (S8) is met.
[0159] The conditions for ending the rinsing cycle can be, for example, when the rinsing cycle reaches a second reference time. The second reference time can vary depending on the sensed load of the clothing. The second reference time can be less than the first reference time.
[0160] Alternatively, the conditions for the end of the rinsing cycle can be met if the cumulative number of executions during the third motion period reaches a reference number.
[0161] When the conditions for ending the rinsing cycle are met, the spin-drying cycle (S9) can be executed. The spin-drying cycle can be executed for a third reference time. The third reference time can vary depending on the sensed load of the clothes.
[0162] Once the spin cycle is complete, the washing of the clothes is finished.
