[0045] Figure 3 An example of the control panel 123 is shown. As described above, the input unit and the display unit are provided at the control panel 123.

[0046] The display unit 128 can be configured to display control signals (or control commands) that can be selected through the input unit.

[0047] The input unit may be configured to include: a first input unit 124 configured to input a control signal requesting power supply; a second input unit 125 configured to request display of information on processes selectable by the user; a third input unit 126 configured to select an option for a process displayed on the display unit 128 (a control command that can be attached to the process or a control command for changing a control command set in the process); and a fourth input unit 127 configured to input a control signal requesting execution of a process selected by the user.

[0048] The second input unit 125 may be composed of two buttons or two touch sensors, which are arranged facing each other with the display unit 128 therebetween.

[0049] The display unit 128 may be set to display a plurality of processes executable by the laundry treating apparatus 100 in a predetermined order. The display unit 128 may be configured to display the processes one by one in the predetermined order whenever the user presses the second input unit 125a provided on the right side of the display unit 128, and to display the processes one by one in the order opposite to the predetermined order whenever the user presses the second input unit 125b provided on the left side of the display unit 128.

[0050] The option commands selectable by the third input unit 126 may be, for example, the water supply amount set for the washing process or the rinsing process, the treatment execution time, the number of repetitions of the rinsing process, the number of executions of the drying process, or the temperature of the water supplied during the washing process or the rinsing process.

[0051] Figure 4 An example of a control method of the laundry treating apparatus is shown. The control method according to the present embodiment includes a washing process S30. The washing process S30 may be configured to include a washing water supply step S31 of supplying water to the tub body 21, a washing rotation step S33 of rotating the drum body 31 within the tub body 21, and a washing drainage step S34 of discharging water from the inside of the tub body 31.

[0052] When the controller controls the water supply valve 243, the washing water supply step S31 is executed. The water supply amount in the washing water supply step S31 may be controlled according to the amount of laundry (laundry amount) loaded in the drum body 31.

[0053] That is, the control method may be configured to include a laundry amount sensing step configured to be executed after the process selection step S10 ends, and then the washing water supply step S31 starts. In this case, the washing water supply step S31 may be configured to supply a predetermined amount of water set for the laundry amount sensed in the laundry amount sensing process to the tub body 21.

[0054] In the detergent supply unit 4Storage space 42 In a state where the detergent is supplied, the detergent supply step S32 for washing can be performed simultaneously with the washing water supply step S31 in the washing process S30.

[0055] The washing rotation step S33 may be composed of a step of rotating the drum body 31 by the motor 35 to separate foreign substances from the laundry by the friction between the laundry and the drum body and the friction between the laundry and water.

[0056] The washing drainage step S34 may be composed of a step of discharging the water stored in the tub body 21 to the outside of the cabinet 1 by controlling the drain valve 252 through the controller.

[0057] In the washing process S30, a washing spin-drying step (not shown) of removing water from the laundry after the washing drainage step S34 is completed may be further performed. The washing spin-drying step may be composed of a step of separating water from the laundry by the centrifugal force generated by rotating the drum 3 at a predetermined RPM.

[0058] The control method may be configured to include a process selection step S10 and an option selection step S20 before the start of the washing process S30.

[0059] The process selection step S10 may be composed of a step of selecting one of multiple processes through the second input unit 125, and the option selection step S20 may be composed of a step of inputting an option command to the selected process through the third input unit 126.

[0060] When the washing process S30 ends, the control method determines whether to request the execution of the fragrance enhancement process (S40) through the option selection step S20.

[0061] When the fragrance enhancement process is not selected in the option selection step S20, the control method executes the rinsing process S50.

[0062] The rinsing process S50 may be configured to include a rinsing water supply step S51 of supplying water to the tub body 21, a rinsing rotation step S53 of rotating the drum body 31 within the tub body 21, and a rinsing drainage step S55 of discharging water from the inside of the tub body 21.

[0063] The rinsing water supply step S51 may be configured to supply a predetermined amount of water set for the amount of laundry loaded in the drum body 31 to the tub body 21. The rinsing rotation step S53 may be composed of a step of rotating the drum body 31 by the motor 35 to separate the detergent and foreign substances remaining in the laundry from the laundry. The rinsing drainage step S55 may be composed of a step of discharging the water stored in the tub body 21 by controlling the drain valve 252.

[0064] When the rinsing process S50 ends, the control method may execute a spin-drying process S80 of removing water from the laundry by rotating the drum body 31 at a predetermined RPM.

[0065] Meanwhile, when the fragrance enhancement process is selected through the option selection step S20 (S40), the control method sequentially executes a first rinsing process S60 and a second rinsing process S70 (fragrance enhancement process).

[0066] The first rinsing process S60 may be configured to execute a first rinsing water supply step S61 of supplying water to the tub body 21, a first rinsing rotation step S63 of rotating the drum body 31, a first rinsing drainage step S65 of discharging water from the inside of the tub body S65, and a first rinsing spin-drying step S66.

[0067] When the first rinsing spin-drying step S66 ends, the control method executes a step S67 of determining whether the number of executions (predetermined number of rinses) set in the first rinsing process S60 is equal to the maximum number (predetermined maximum number) that can be set in the first rinsing process.

[0068] When the set number of rinses is less than the predetermined maximum number, the control method causes the first rinsing process S60 to execute the set number of executions (S68). After causing the first rinsing process S60 to execute the set number of executions, the control method executes the second rinsing process S70.

[0069] However, when the set number of rinses is equal to the predetermined maximum number (S67), the control method causes the first rinsing process S60 to execute a number of times that is 1 less than the set number of executions (S69). In this case, the second rinsing process 70 may start after causing the first rinsing process S60 to execute a number of times that is 1 less than the set number of executions.

[0070] The reason for limiting the set number of rinses to not more than the predetermined maximum number is to minimize the operation time of the laundry processing apparatus 100 while ensuring the effects of the washing process and the rinsing process. Therefore, by reducing the number of executions of the first rinsing process S60 when the set number of rinses is equal to the predetermined maximum number (S67), the effect of minimizing the operation time of the laundry processing apparatus can be achieved.

[0071] Meanwhile, the number of executions of the first rinsing process ( Set number of rinsing times ) may be configured to be input by the user through the option selection step S20, or may be configured to be input through a separate step independent of the option selection step S20.

[0072] The second rinsing process S70 may be configured to include a second rinsing water supply step S71 of supplying water to the tub body 21, a detergent supply step S73 of supplying an aromatic detergent to the tub body 21, a second rinsing rotation step S75 of rotating the drum body 21, and a second rinsing drainage step S77 of discharging the water stored in the tub body 21.

[0073] The amount of water supplied to the tub body 21 in the second rinsing water supply step S71 is preferably less than the amount of water supplied to the tub body 21 in the first rinsing water supply step S61. When the amount of water supplied to the tub in the second rinsing water supply step S71 increases, the concentration of the aromatic detergent increases. Therefore, the control method can cause a large amount of fragrance to remain in the laundry after the washing is completed.

[0074] In addition, the execution time of the second rinsing process S70 may be set to be the same as the execution time of the first rinsing process S60, or may be set to be shorter than the execution time of the first rinsing process S60.

[0075] The second rinsing process S70 is performed in a state where the concentration of the aromatic detergent is high. Therefore, even when the execution time of the second rinsing process S70 is set to be equal to or less than the execution time of the first rinsing process S60, compared with conventional laundry treatment apparatuses, the fragrance remaining in the laundry after the operation of the laundry treatment apparatus is completed can be rich (the fragrance remaining in the laundry after the operation of the laundry treatment apparatus can be stronger than that of conventional laundry treatment apparatuses).

[0076] In addition, when the execution time of the second rinsing process S70 is set to be equal to or less than the execution time of the first rinsing process S60, it is possible to expect the effect of increasing the amount of fragrance remaining in the laundry while reducing the operation time of the laundry treatment apparatus.

[0077] Since the amount of water supplied in the second rinsing water supply step S71 is set to be small, the execution time of the second rinsing water supply step S71 and the execution time of the second rinsing drainage step S77 can be shorter than the execution time of the water supply step S61 and the drainage step S65 set in the first rinsing process S60, respectively. Therefore, when the execution time of the second rinsing process S70 is set to be equal to the execution time of the first rinsing process S60, the control method can set the execution time of the second rinsing rotation step S75 to be equal to the execution time of the first rinsing rotation step S63 or longer than the execution time of the first rinsing rotation step S63.

[0078] When the execution time of the second rinsing rotation step S75 is set to be longer than the execution time of the first rinsing rotation step S63, it has a useful effect of increasing the amount of fragrance remaining in the laundry.

[0079] After the second rinse drainage step S77 ends, after performing the spin-drying process S80, the control method ends.

[0080] Meanwhile, when the execution of the second rinse process S70 is not requested in the option selection step S20, it can be configured to perform the detergent supply step S73 in the final first rinse water supply step S61 of the first rinse process S60.

[0081] The above-mentioned Laundry treatment device and its control method can be implemented in a state modified into various forms. Therefore, the scope of the present disclosure is not limited to the above-described embodiments.
