Description

Laundry treatment equipment and laundry treatment method

[0001] This specification relates to a laundry treatment device and a laundry treatment method.

[0002] In general, a laundry treatment device is a device that processes laundry by applying physical and chemical actions to the laundry.

[0003] The laundry treatment device may include a tub that is accommodated in a hanging form inside a cabinet, and a drum that rotates within the tub while laundry (or fabric) is accommodated therein.

[0004] In order to remove contamination from the laundry, the drum may be rotated. The laundry within the drum may be rotated or dropped by the rotation of the drum.

[0005] A typical laundry treatment method may include a washing cycle, a rinsing cycle, and a spin-drying cycle.

[0006] In order to improve the washing performance of the laundry, the rotation of the drum can be controlled to rotate at high speed or have various motions, and the temperature of the washing water can be increased using a heating unit.

[0007] However, as the mechanical force transferred to the laundry increases to improve washing performance, microplastics are separated from the laundry, which increases the amount of separated microplastics. This increase in microplastics also increases the risk of environmental pollution due to microplastics contained in the drained wash water.

[0008] Prior art document 1, Korean Patent Publication No. 2023-0132990, discloses a laundry treatment method for effectively washing laundry requiring delicate treatment, but does not disclose a technology for reducing the amount of microplastics generated.

[0009] Prior art document 2, Korean Patent Publication No. 2023-0059161, discloses a technology for effectively separating microplastic fibers separated from laundry from wash water, but does not disclose a technology for reducing the amount of microplastics generated.

[0010] One embodiment provides a laundry treatment device and a laundry treatment method capable of reducing the amount of microplastics generated during the laundry treatment process.

[0011] Alternatively or additionally, one embodiment provides a laundry treatment device and a laundry treatment method capable of reducing the amount of heating of a heating unit operating during the laundry treatment process.

[0012] A method for treating laundry according to one aspect may include a washing process, a rinsing process, and a dehydration process.

[0013] The above washing process may include a first motion section and a second motion section following the first motion section.

[0014] In the first motion section, the drum receiving the laundry can stop for a first stop time after operating in the first motion.

[0015] In the second motion section, the drum can be stopped for a second stop time after operating in the second motion.

[0016] After the first motion section ends, the second motion section may be performed repeatedly multiple times, and then the first motion section may be performed again.

[0017] In the first motion section, the first motion is performed for a first time, and the first stop time may be greater than the first time.

[0018] The above second stopping time may be greater than the above first time.

[0019] During the first time, the drum can rotate multiple times in one direction.

[0020] In the first motion section, the drum can be rotated multiple times in one direction to operate in the first motion.

[0021] In the second motion section, the drum can repeat forward and reverse rotation to operate in the second motion.

[0022] In the second motion section, the second motion is performed for a fourth time, and the second stop time may be greater than the fourth time.

[0023] The above rinsing process may include a third motion section. In the above rinsing process, the third motion section may be performed multiple times.

[0024] In the third motion section, the drum may be stopped for a third stop time after operating in the second motion.

[0025] The third stopping time may be equal to or less than the second stopping time. The third stopping time may be equal to or less than the first stopping time.

[0026] In the third motion section, the drum can repeat forward and reverse rotation to operate in the second motion.

[0027] In the third motion section, the second motion is performed for a sixth time, and the third stop time may be greater than the sixth time.

[0028] The actual working rate in the above washing cycle is a first actual working rate, the actual working rate in the above rinsing cycle is a second actual working rate, and the second actual working rate may be greater than the first actual working rate.

[0029] The operating ratio (%) can be calculated by (operating time of the drive unit to rotate the drum / total time in one cycle) x 100.

[0030] One cycle may be from the start point of the first motion section to the end point of the second motion section of the last turn.

[0031] A laundry treatment device according to another aspect may include: a cabinet; a tub accommodated within the cabinet and storing laundry; a drum positioned within the tub and containing laundry; a driving unit for rotating the drum; and a control unit for controlling the driving unit.

[0032] The above control unit can cause a washing process and a rinsing process to be performed to wash the laundry.

[0033] The above washing process may include a first motion section and a second motion section following the first motion section.

[0034] In the first motion section, the drum receiving the laundry may stop for a first stop time after operating in the first motion. In the second motion section, the drum may stop for a second stop time after operating in the second motion.

[0035] The above rinsing cycle may include a third motion section. In the third motion section, the drum may be stopped for a third stop time after operating in the second motion.

[0036] In the first motion section, the first motion is performed for a first time, and the first stop time and the second stop time may be greater than the first time.

[0037] After the first motion section ends, the second motion section may be performed repeatedly multiple times, and then the first motion section may be performed again.

[0038] The laundry treatment method according to another aspect may include a washing cycle and a rinsing cycle.

[0039] In the above washing cycle, the motion of the drum that receives the laundry may be composed of only the first motion and the second motion, and in the above rinsing cycle, the motion of the drum may be composed of only the second motion.

[0040] The first motion may be a motion in which the drum rotates multiple times, and the second motion may be a motion in which the drum rotates repeatedly within a range of half a turn or less in the forward or reverse direction.

[0041] According to one embodiment, there is an advantage in that the amount of microplastics generated during the laundry treatment process can be reduced while ensuring washing power.

[0042] According to one embodiment, there is an advantage in that the amount of heating of a heating unit operating during the laundry treatment process can be reduced.

[0054] Fig. 1 is a front view of a laundry treatment device according to the present embodiment. Fig. 2 is a front view showing the internal structure of a laundry treatment device according to the present embodiment, and Fig. 3 is a longitudinal cross-sectional view showing the internal structure of a laundry treatment device according to the present embodiment. Fig. 4 is a control block diagram of a laundry treatment device according to the present embodiment.

[0055] Figures 2 and 3 illustrate a state in which a portion of the cabinet has been removed.

[0056] Referring to FIGS. 1 to 4, the laundry treatment device (1) of the present embodiment may include a cabinet (10) forming an outer shape.

[0057] The above cabinet (10) can be formed by a single member or by combining multiple members.

[0058] The above laundry treatment device (1) may further include a tub (20) placed inside the cabinet (10). Washing water may be accommodated in the tub (20).

[0059] The laundry treatment device (1) may further include a drum (30) that is placed inside the tub (20) and accommodates laundry. The drum (30) may be rotated by a driving unit (40).

[0060] The laundry treatment method of the present embodiment can be applied, for example, when the rotation center (C) of the drum (30) is positioned horizontally, but is not limited thereto, and the laundry treatment method of the present embodiment can be applied in the same manner or in a modified form even when the rotation center (C) of the drum (30) is inclined with respect to the horizontal plane.

[0061] If the laundry treatment method of the present embodiment is modified and applied, the length of the rotation time of the drum or the length of the stop time or the number of rotations of the drum in the microplastic reduction course described later may be changed.

[0062] The cabinet (10) includes an input hole for inputting laundry, and the input hole can be opened and closed by a door (11). Each of the tub (20) and the drum (30) can include an opening that can communicate with the input hole. When the door (11) is opened, laundry can be received into the drum (30) through the input hole and the opening.

[0063] The laundry treatment device (1) may further include a detergent box (14) in which detergent is contained. The laundry treatment device (1) may further include a control panel (13).

[0064] The above control panel (13) may include an input unit (71) for inputting various commands. Through the input unit (71), various operation commands such as washing course selection, operation time for each cycle, and reservation can be input.

[0065] The above washing course may include various courses such as a standard course, and in particular, in the present embodiment, may include a microplastic reduction course.

[0066] The above control panel (13) may include a display unit (72) that displays the operating status of the laundry treatment device (1). The input unit (71) and the display unit (72) may be separate components, and the display unit (72) may also function as the input unit (71).

[0067] The laundry treatment device (1) may further include a heating unit (73). The heating unit (73) may heat the wash water. The heating unit (73) may heat the wash water so that the temperature of the wash water during the washing process in the microplastic reduction course becomes within a reference temperature range.

[0068] The upper limit temperature of the above reference temperature range may be 40 degrees or a temperature similar to 40 degrees. The lower limit temperature of the above reference temperature may be 30 degrees or a temperature similar to 30 degrees.

[0069] If the temperature of the washing water is higher than the upper limit temperature, washing performance may be improved, but there is a concern that the amount of microplastics may increase.

[0070] Contaminants (sebum, sweat, blood, etc.) attached to laundry are composed of protein components, and washing efficiency can be improved when the temperature of the washing water is within the above standard temperature range.

[0071] Therefore, by controlling the heating unit (73) so that the temperature of the washing water is within the reference temperature range, not only can the generation of microplastics be reduced, but also the separation performance of the pollutant source can be improved, while reducing the heating amount of the heating unit (73), thereby reducing power consumption, which has the advantage of being possible.

[0072] The above laundry treatment device (1) may further include a water supply valve (75) that controls the inflow of washing water from an external water source.

[0073] In the washing process, the amount of laundry can be detected, and the amount of water supplied corresponding to the detected amount of laundry can be determined. The water supply valve (75) can be controlled to supply washing water in the amount of water supplied determined.

[0074] The above laundry treatment device (1) may further include a drainage device (50) for draining the laundry water in the tub (20).

[0075] The above laundry treatment device (1) may further include a damping unit (60) connected to the lower portion of the tub (20) to reduce vibration.

[0076] The laundry treatment device (1) may further include a control unit (70). The control unit (70) may control the driving unit (40). The control pattern and operating time of the driving unit (40) may be determined for each washing course.

[0077] The above control unit (70) can control only the driving unit (40) or can control other components other than the driving unit (40).

[0078] Below, we will explain how to handle laundry.

[0079] Fig. 5 is a flow chart showing a laundry treatment method according to the present embodiment, and Fig. 6 is a flow chart showing a washing process in a microplastic reduction course.

[0080] Fig. 7 is a drawing for explaining the motion in the washing process of the microplastic reduction course, and Fig. 8 is a drawing for explaining the flow of laundry according to the motion in the washing process of the microplastic reduction course.

[0081] Figure 9 is a drawing for explaining the motion in the rinsing process of the microplastic reduction course.

[0082] Referring to FIGS. 5 to 9, the laundry treatment method of the present embodiment may include a washing process, a rinsing process, and a dehydration process.

[0083] Typically, a washing course may include the washing cycle, rinsing cycle, and spin-drying cycle.

[0084] The microplastic reduction course of the present embodiment may also include the washing process, rinsing process, and dehydration process.

[0085] The microplastic reduction course can be selected and a start command can be input through the input unit (71).

[0086] When the above start command is input, a load detection step can be performed (S1). In the load detection step, the driving unit (40) can be operated so that the drum (30) rotates.

[0087] Since the method for detecting the amount of baggage can be implemented using known technology, a detailed description will be omitted.

[0088] Once the above laundry volume detection step is completed, a water supply step may be performed (S2). If a laundry volume is detected in the above laundry volume detection step, a water supply amount may be determined in response to the detected laundry volume. In the water supply step, the water supply valve (75) may be controlled so that washing water is supplied in the determined water supply amount.

[0089] Once the water supply step is completed, a step of heating the wash water may be performed (S3). As described above, the heating unit (73) may be operated so that the temperature of the wash water falls within the reference temperature range to improve the separation performance of contaminants.

[0090] After the above washing water heating step is completed or during the washing water heating step, a washing process may be performed (S4). Alternatively, the washing process of the present embodiment may include a water supply step and a heating step.

[0091] The microplastic reduction course is a course that reduces the mechanical force inside the laundry treatment machine that is transferred to laundry such as clothing, thereby minimizing damage to the fabric and reducing the emission of microplastics.

[0092] In particular, the above microplastic reduction course is a course that aims to maintain the level of washing while minimizing the transfer force during washing and rinsing by considering special materials (such as polyester fibers) that shed a lot of microplastics.

[0093] There are three main forces involved in the mechanical action within a laundry machine: centrifugal force transmitted to the fabric as the drum rotates, frictional force (with the drum wall), and gravity (the impact of a drop). There is also frictional force (between fabrics) and shear force generated as the fabric moves.

[0094] When the drum (30) operates without changing direction at a constant speed below the acceleration of gravity, the load inside the drum (30) accumulates force in the same area, inducing interference and friction between fabrics, which maximizes damage. As the mechanical force transmitted to the fabric increases, both hydrophilic and hydrophobic fibers break at the surface, causing fibrillation. Fibers that rise to the surface in this way are shed and become microfibers when subjected to continuous mechanical force.

[0095] Therefore, in the present embodiment, the microplastic reduction course may include a motion that performs washing by minimizing friction and gravity transmitted to the fabric.

[0096] In order to apply impact and shear forces while minimizing the friction transmitted to the fabric, it is necessary to ensure continuous reversal of the fabric flow and physical space for individual movement of the fabric within the drum.

[0097] In the microplastic reduction course of this embodiment, damage to the fabric is minimized by utilizing a motion that can reverse the position of the fabric so that the impact force and shear force transmitted to the fabric are distributed rather than concentrated on a part of the fabric.

[0098] In addition, in the case of the microplastic reduction course of the present embodiment, a motion is used that can secure washing performance by utilizing the impact force of a drop, which is a problem in that the physical force transmitted to the fabric is minimized and washing efficiency is reduced.

[0099] In the washing process of this embodiment, the washing power can be secured through a combination of the first motion and the second motion of the drum and the actual operation rate described below.

[0100] The above first motion may be a motion in which the drum rotates multiple times at a speed of 1G or less, thereby providing a constant falling force to the laundry, thereby generating a transmission force for washing.

[0101] The second motion may be a motion in which the drum repeatedly rotates forward or backward within a range of half a rotation or less at a speed of 1G or less. By the second motion, the state of the laundry cloth can be changed (cloth reversal) and the contact area with the laundry liquid can be changed.

[0102] Fibers made of special materials that shed a lot of microplastics have lower hygroscopicity than materials such as cotton when considering their material properties, so they have fewer functional groups that can absorb water.

[0103] Therefore, in the rinsing cycle, the detergent can be easily removed even with low mechanical power, so rinsing is possible with low mechanical power (for example, only the second motion) compared to cotton fibers.

[0104] For example, in the microplastic reduction course of the present embodiment, the washing process may include a first motion section and a second motion section following the first motion section.

[0105] Referring to FIG. 7, the first motion section may include a first rotation section in which the drum (30) (or driving unit) rotates. The first motion section may further include a first stop section in which the drum (30) (or driving unit) stops.

[0106] In the first rotation section, the drum (30) can operate in a first motion (S41). The first motion of the drum (30) is illustrated in (A) of Fig. 8.

[0107] When the drum (30) operates in the first motion, laundry (L) may rotate along the drum (30) and then fall from a predetermined height (floor drop flow) (see arrow A). That is, the laundry may not remain attached to the drum (30) and may fall during the rotation of the drum (30).

[0108] For example, the drum (30) may be rotated in one direction at a first RPM for a first time. The first RPM may be, for example, 46 RPM, but may be changed.

[0109] After the drum (30) has rotated for the first time, the drum (30) may be stopped for a second time. The first time is the time of the first rotation section, and the second time is the time of the first stop section. The second time may be referred to as the first stop time.

[0110] The sum of the first time and the second time is the total time of the first motion section.

[0111] The second time may be longer than the first time.

[0112] For example, the first time may be A seconds and the second time may be 5A seconds. For example, the first time may be 5 seconds and the second time may be 25 seconds.

[0113] However, it is not limited thereto, and the length of the first time, the length of the second time, and the ratio of the first time and the second time in the first rotation section can also be varied.

[0114] Alternatively, in the first rotation section, the drum (30) may be rotated P times. After the drum (30) is rotated P times, it may be stopped for the second time.

[0115] In the present embodiment, the first motion section may be performed L times. L may be a natural number greater than or equal to 1. For example, the second motion section may be performed after the first motion section is performed once. Of course, it is also possible for the second motion section to be performed after the first motion section is performed multiple times.

[0116] Referring to Fig. 7, the second motion section may include a second rotation section in which the drum (30) (or driving unit) rotates. The second motion section may include a second stop section in which the drum (30) (or driving unit) stops.

[0117] In the second rotation section, the drum (30) can operate in a second motion (S42). The second motion of the drum (30) is illustrated in (B) of FIG. 8. When the drum (30) operates in the second motion, laundry (L) can be reversed within the drum (30) (fabric reverse flow). For example, laundry can rotate along the drum (30) and then be reversed at a specific location (see arrows B and C).

[0118] For example, the drum (30) may be rotated in one direction (forward rotation) and then rotated in the opposite direction (reverse rotation). In the second rotation section, the forward and reverse rotations of the drum (30) may be repeated. As described above, the drum (30) may be repeatedly rotated within a range of half a turn or less.

[0119] When the drum (30) rotates forward or backward, the drum (30) can rotate at the second RPM.

[0120] In the second rotation section, the drum (30) can rotate N times. When calculating the number of rotations of the drum (30), forward rotation can be considered as the first rotation and reverse rotation can be considered as the second rotation. The N can be 4, for example, but can be changed.

[0121] After the drum (30) has rotated N times, the drum (30) may be stopped for a third time. The third time is the time of the second stop section. The third time may be referred to as the second stop time.

[0122] The third time may be longer than the time required for the above drum (30) to rotate N times.

[0123] The third time period may be the same as or different from the second time period. The third time period may be, for example, 25 seconds, but may be changed.

[0124] As another example, the second rotation section may be performed for a fourth time. In this case, the fourth time may be shorter than the third time. The fourth time may be shorter than the first time. The lengths of each of the fourth time and the third time may be changed, and the ratio of the fourth time and the third time in the second motion section may also be changed.

[0125] In the present embodiment, the second motion section may be repeated B times. B may be a natural number greater than 2.

[0126] The number of times the second motion section is performed may be greater than the number of times the first motion section is performed. For example, the first motion section may be performed once and the second motion section may be performed twice, but this may be changed.

[0127] In this embodiment, the period from the start of the first motion section to the end of the second motion section of the last cycle may be considered one cycle. In the washing process, the cycle may be repeated.

[0128] In a washing cycle, the actual working rate may be maintained at a first actual working rate or within a first range in each cycle. The first actual working rate may be included within the first range.

[0129] In this specification, the actual operating rate (%) is

[0130] (Actual operating time of the drive unit / Total time in one cycle) x 100

[0131] can be calculated by

[0132] The actual operating time of the above driving unit may be the rotation time of the drum.

[0133] In each cycle, the rotation direction of the drum (30) during the first motion may vary. For example, in the first cycle, the drum (30) may rotate in the forward direction during the first motion, in the second cycle, the drum (30) may rotate in the reverse direction during the first motion, and in the third cycle, the drum (30) may rotate in the forward direction during the first motion.

[0134] If the drum (30) rotates in the same direction for each cycle, the laundry falls in one direction, so the washing power increases, but there is a risk that the laundry damage will increase due to the accumulation of force in a portion of the laundry. However, if the rotation direction of the drum (30) is changed for each cycle as in the present embodiment, the location of the portion where the force is accumulated is changed due to the laundry reversal, so that the laundry damage can be reduced.

[0135] In addition, in the first motion section, the rotation direction of the drum (30) does not change, so force is accumulated in a part of the gun, but in the second motion section, the force transmitted to the gun by the gun reversal flow can be sprayed, so that damage to the gun can be reduced.

[0136] While the above washing process is being performed, it can be determined whether the end condition of the above washing process is satisfied (S5).

[0137] For example, when the above washing process termination condition is satisfied, the washing process progress time may reach a first reference time. The first reference time may vary depending on the detected amount of laundry.

[0138] Alternatively, the termination condition of the washing process may be satisfied when the number of accumulated cycles reaches a reference cycle. Alternatively, the termination condition of the washing process may be satisfied when the number of times the first motion section is performed reaches a reference number or when the number of times the second motion section is performed reaches a reference number.

[0139] When the above washing cycle termination condition is satisfied, dehydration of the washing water used in the washing cycle can be performed (washing dehydration) (S6).

[0140] When the washing and dehydration are completed, a rinsing cycle can be performed (S7). Rinse water supply can also be performed during the rinsing cycle.

[0141] In the microplastic reduction course of the present embodiment, the rinsing process may include a third motion section.

[0142] The third motion section may be the same as or different from the second motion section in the washing cycle.

[0143] Referring to FIG. 9, the third motion section may include a third rotation section in which the drum (30) (or driving unit) rotates, and a third stop section in which the drum (30) (or driving unit) stops.

[0144] In the third rotation section, the drum (30) can operate in the second motion. The laundry can be reversed within the drum (30) by the second motion of the drum (30) (fabric reverse flow).

[0145] For example, the drum (30) may be rotated in one direction (forward rotation) and then rotated in the opposite direction (reverse rotation). In the third rotation section, the forward and reverse rotations of the drum (30) may be repeated.

[0146] The motion of the drum (30) is the same in each of the second and third rotation sections, and the number of forward and reverse rotations of the drum (30) may be the same or different.

[0147] In the third rotation section, the drum (30) can be rotated M times. When calculating the number of rotations of the drum (30), forward rotation can be considered as the first rotation and reverse rotation can be considered as the second rotation. The M can be the same as or different from the N.

[0148] After the drum (30) has rotated M times, the drum (30) may be stopped for a fifth time. The fifth time is the time of the third stop section. The fifth time may be referred to as the third stop time.

[0149] The fifth time may be longer than the time when the drum (30) rotates M times.

[0150] The fifth time may be the same as or different from the third time. If the fifth time is different from the third time, the fifth time may be shorter than the third time.

[0151] The above 5th time may be 20 seconds for example, but can be changed.

[0152] As another example, the third rotation section may be performed for a sixth time period. In this case, the sixth time period may be less than the fifth time period. The sixth time period may be the same as or different from the fourth time period.

[0153] It is also possible to change the length of each of the fifth and sixth times, and it is also possible to change the ratio of the fifth and sixth times in the third motion section.

[0154] In the present embodiment, the third motion section in the rinsing process can be repeatedly performed until the rinsing process is completed.

[0155] In the rinsing cycle, the actual working rate may be maintained at the second actual working rate or within a second range. The second actual working rate may be included within the second range.

[0156] The second operating rate may be greater than the first operating rate. The first operating rate and the second operating rate may be 20% or less.

[0157] While the above rinsing process is being performed, it can be determined whether the termination condition of the above rinsing process is satisfied (S8).

[0158] For example, the rinsing cycle termination condition may be satisfied when the rinsing cycle's progress time reaches a second reference time. The second reference time may vary depending on the detected amount of laundry. The second reference time may be shorter than the first reference time.

[0159] Alternatively, when the termination condition of the above rinsing process is satisfied, it may be the case that the number of times the third motion section is performed reaches a reference number.

[0160] When the termination condition of the above rinsing process is satisfied, a dehydration process can be performed (S9). The dehydration process can be performed for the same third reference time. The third reference time may vary depending on the detected amount of laundry.

[0161] When the above dehydration process is completed, the washing of the laundry can be completed.
