Description

TECHNICAL FIELD [0002] A laundry treating apparatus and a control method of the same

The present invention relates to a laundry treatment apparatus and a method for controlling the laundry treatment apparatus.

In general, a clothes treatment apparatus refers to an apparatus capable of washing or drying clothes or the like, or washing or drying clothes. Here, the laundry treatment apparatus may perform only a washing or drying function, or may perform both washing and drying.

Such a clothes treatment apparatus is provided with an arbitrary course or option for washing or drying clothes, and the execution time of the course or option is calculated based on the amount of laundry of the clothes. For example, when the amount of clothes is large, the execution time is set to be relatively long, and when the amount of clothes is small, the execution time is set to be relatively small.

1 is a diagram illustrating a control method for performing an arbitrary course or option of a conventional laundry treatment apparatus. (See Korean Patent Publication Nos. 10-2009-0077097 and 10-2008-0102611, etc.)

FIG. 1(a) is a diagram illustrating a control method in which a conventional laundry treatment apparatus performs an arbitrary course or option.

Referring to FIG. 1A , in the conventional clothes treatment apparatus, a power supply step (s1) of supplying power to the laundry treatment apparatus by inputting a power button (on), and an appropriate course or option are selected from the control panel of the laundry treatment apparatus. It may include a selection step (s2) of selecting, and a starting step (s3) of inputting an execution button for executing the course or option.

When the conventional laundry treatment apparatus is provided as a front load type washing machine having an opening in the front of the cabinet through which clothes are put in, when the starting step s3 is performed, the door lock for fixing the opening to the cabinet Step s4 may be performed.

Thereafter, the conventional laundry treatment apparatus performs a laundry weight sensing step (S5) of detecting the amount of laundry through a current value applied while rotating a drum or the like containing the clothes. When the laundry amount of the clothes is calculated, the control unit of the conventional clothes processing apparatus performs a time display step (S6) of displaying the expected execution time of the selected course or option to the user, and automatically executes the course or option. (S7) is performed.

However, the step of detecting the amount of laundry (S5) and the step of displaying the time (S6) of the conventional laundry treatment apparatus are performed after the starting step (S3) of the user executing a course or option. Accordingly, there is a problem in that the user is forced to input the execution of the course or option without receiving information on the amount of clothing or the expected execution time.

As a result, the user cannot actively control the execution time of the course or option, and the time display step (s6) has a problem in that it cannot perform a role beyond simply displaying simple information at the service level to the user.

Furthermore, in the conventional clothing processing apparatus, even if the execution time displayed in the time display step s6 does not match the user's current intention or situation, it does not give the user room to take active measures such as adding or reducing clothing. There was a problem.

Also, in the conventional laundry treatment apparatus, even if the execution time of the selected course or option does not match the intention, to change the course or option, the course or option can be canceled or changed unless an active action is taken, such as arbitrarily turning off the power of the washing machine again. There was an impossible problem.

This inconvenience is further maximized when the conventional clothing processing apparatus is remotely controlled.

1(b) shows the rotational state of the drum when the conventional laundry treatment apparatus senses the amount of laundry.

Referring to FIG. 1B , in the conventional laundry treatment apparatus, the drum D is rotated in the I direction to detect the amount of the laundry L.

Specifically, the conventional clothes treatment apparatus calculates the weight of the clothes L by measuring a current applied to or output from a driving unit that rotates the drum while rotating the drum D in the I direction.

In a conventional laundry treatment apparatus, when the drum D is rotated to detect the amount of laundry, the clothes L on the bottom surface of the drum rise inside the drum D and then fall in the II direction due to gravity to the inner wall of the drum. can only be separated from

Accordingly, there is a limitation in that the conventional laundry treatment apparatus must align the applied or output current values while continuously rotating the drum D in the I direction for one or more rotations in order to detect the correct weight of the clothes L.

As a result, the conventional clothes treatment apparatus has a problem in that it takes more time to sense the amount of clothes than the time to continuously rotate the drum.

In addition, in the conventional clothes treatment apparatus, since the time required for the weight detection step (S5) is set to be relatively long, the time display step (S6) for displaying the execution time of a course or option cannot be quickly guided to the user.

Therefore, there is a problem in that the conventional clothes treatment apparatus fundamentally blocks the possibility that the user can utilize the laundry amount information or the expected execution time of the clothes to the user.

Moreover, the conventional clothes treatment apparatus has a problem in that the user cannot control the execution time of a predetermined course or option, so that the user's convenience cannot be guaranteed.

An object of the present invention is to provide a laundry treatment apparatus capable of immediately guiding a user of an expected execution time of the course or option prior to performing the course or option.

A sensing unit for detecting whether the door 13 is locked to the cabinet 10 may be installed in at least one of the door 13 and the cabinet 10 , and the sensing unit is controlled by the control unit p can be controlled.

On the third display unit 133 , the user may select a course or option, or may display a standard course or option execution time.

Meanwhile, the display unit 16 may also be provided to guide the amount of detergent required when performing the plurality of courses or options. The execution time of the course or option varies depending on the amount of laundry. In addition, the amount of detergent for performing a plurality of courses or options may also vary depending on the amount of laundry.

Accordingly, when the control unit P senses the amount of clothing, at least one of the execution time of the course or option and the amount of detergent required for the course or option may be displayed on the display unit 17 .

For example, the expected execution time of the course or option may be displayed on the third display unit 133 , and the required amount of detergent may be displayed on the second display unit 132 .

The laundry treatment apparatus of the present invention may first detect the amount of laundry before the execution unit 170 is input, and display the expected time of the selected course or option and the required amount of detergent on the display unit 16 .

To this end, the controller P of the laundry treatment apparatus of the present invention may be provided to sense the amount of laundry before the execution unit 170 is input.

By controlling the driving unit 9, the control unit P can calculate the laundry amount of clothes through the current applied or output to the driving unit 9, even before the execution unit 170 is input. It is possible to display the estimated execution time of the selected course or option to the user.

Accordingly, the user can be immediately informed of the expected execution time of the course or option before performing the selected course or option. Alternatively, it may be induced to select an option.

In this way, the user can instantly change from the course or option initially selected by the user to the course or option suitable for his or her situation.

In addition, the user can change the course or option while checking the estimated execution time of several courses or options before executing the selected course or option.

In addition, the user may input an appropriate amount of detergent by checking the required amount of detergent suitable for the clothes in the current state for any one course or option among the plurality of courses or options.

Meanwhile, the control panel 16 of the laundry treatment apparatus of the present invention may further include a time adjusting unit 200 capable of changing the execution time of the course or option to be performed.

The time adjusting unit 200 may be provided in such a way that some buttons of the option selection unit 160 are input after the course or option is selected, or it may be provided as a separate button in the control panel 16 . .

For example, when the time adjusting unit 200 is provided as a separate button, the user can extend or reduce the expected execution time of the selected course or option after inputting the time adjusting unit 200 . .

The extension or reduction of the expected execution time may be performed through input of some buttons of the option selection unit 160 .

6 illustrates an embodiment of a control method for detecting the laundry amount of clothes before input to the execution unit 170 .

When the power supply unit 120 of the laundry treatment apparatus of the present invention is input, power may be supplied to the water supply unit 70 , the driving unit 9 , and the drain unit 80 , and power may also be supplied to the control unit P. have.

The control unit P may be set to detect the amount of laundry of the clothes when the power supply unit 120 is input and power is supplied.

That is, in the laundry treatment apparatus of the present invention, an essential condition for detecting the amount of laundry may be the input of the power supply unit 120 .

Therefore, even when the user opens the door 13 before inputting the power supply unit 120 , then puts clothes into the drum 30 and closes the door 13 , the control unit P controls the The amount of laundry in clothes can be detected immediately.

The controller P may calculate an expected time for performing a specific course or option according to the amount of laundry.

To this end, the control unit P may recognize the estimated time corresponding to the laundry amount of the clothes in the storage unit P2.

In addition, in the storage unit P2, the amount of detergent required when performing an arbitrary course or option on the amount of laundry of the clothes may also be arranged as data. The control unit P may calculate the amount of detergent required when washing the clothes in the course or option in the storage unit P2 .

For example, in the laundry treatment apparatus of the present invention, when the power supply step (A1) of supplying power by inputting the power supply unit 120 of the laundry treatment apparatus and the power supply step (A1) are performed, the drum 30 is A laundry weight detection step (A2) of detecting the laundry weight of the received clothing may be performed.

When the amount of clothes is detected in the step of detecting the amount of clothes (A2), at least one of the laundry amount of the clothes, the expected execution time of the course or option for washing the clothes, and the amount of detergent required for the course or option is displayed on the display unit 16 An information display step (A3) in which one is displayed may be performed.

In the information display step (A3), a preset standard course corresponding to the weight of the clothing or an execution time corresponding to a standard option may be displayed.

The user can check the amount of clothes displayed in the information display step A3, the execution time of a preset course or option, and compare it with his/her own schedule, and check the amount of detergent.

If the user is satisfied with the information displayed in the information display step (A3), the user may input the execution unit 170 . The control unit P may perform an execution input step A6 of detecting that the execution unit 170 is input.

When the execution input step A6 is performed, the control unit P controls the locking unit to lock the door 13 to the cabinet 10 to prevent the door 13 from being arbitrarily opened. have.

In addition, when the execution input step A6 is performed, the controller P may perform one or more of a washing cycle, a rinsing cycle, and a dehydration cycle according to the course or option setting. After the execution input step A6, the procedure of detecting the laundry amount of the clothes may be omitted. Accordingly, it is possible to prevent the overall washing time from being delayed.

Meanwhile, in the information display step (A3), after the user confirms at least any one of the amount of clothing, the execution time of a preset course or option, and the amount of detergent, the course selection unit 140 or the option selection unit 160 is input. A course setting step (A4) may be further performed.

For example, the user may check the laundry amount of the clothes through the course setting step A4 and then input the course selection unit 140 or the option selection unit 160 , and after confirming the execution time, the course selection unit (140) or the option selection unit 160 can be input to change the course or option.

When the course setting step (A4) is performed, the control unit (P) recalculates the expected execution time or detergent amount of the changed course or option corresponding to the laundry amount of the clothing and transmits it to the display unit 16 ( A5) can be performed.

At least one of the expected execution time of the changed course or option and the changed amount of detergent may be displayed on the display unit 16 in the change display step A5.

The user can input the execution unit 170 when it is determined that the expected execution time or the amount of detergent is suitable, and when the expected execution time or the amount of detergent is not suitable, the course selection unit 140 or the option selection unit 160 ) can be re-entered.

The control unit P may perform the execution input step A6 when detecting the input of the execution unit 170, and set the course when detecting the input of the course selection unit 140 or the option selection unit 160 Step A4 and change display step A5 may be performed again.

7 illustrates another control method for detecting the amount of laundry before input to the execution unit 170 of the laundry treatment apparatus according to the present invention.

The control unit P may be provided to detect the amount of laundry of the clothes before the execution unit 170 is input when the opening/closing of the door 13 is sensed. That is, the condition for detecting the laundry amount of the clothes may be opening and closing of the door 13 .

The laundry treatment apparatus of the present invention may perform the opening/closing step (B1) of sensing the opening/closing of the door 13 . When the opening/closing of the door 13 is detected in the opening/closing step (B1), the control unit P may perform a laundry weight sensing step (B2) of detecting the amount of the clothes, and according to the detected amount of clothes, The information display step (B3) of displaying one or more of the amount of laundry, the execution time of a preset course or option, and the required amount of detergent may be performed.

After the information display step (B3), the control unit (P) can perform the execution input step (B6) by detecting whether the user inputs the execution unit 170, and the user selects a course or option It is possible to perform the course setting step (B4) and the change display step (B5) by detecting whether to change.

The information display step B3, the course setting step B4, the change display step B5, and the execution input step B6 may be the same as in the above-described embodiment.

The opening and closing of the door 13 may mean that there is a high probability that clothes are put into the drum 30 . Also, the opening and closing of the door 13 may mean that the amount of clothes in the drum 30 is increased or decreased.

Accordingly, upon detecting that the door 13 is opened or closed, the laundry treatment apparatus of the present invention immediately detects the amount of laundry and informs the user of the amount of laundry, the expected execution time or changed execution time of the course or option, and the required amount of detergent. Alternatively, it can guide the amount of changed tax.

8 illustrates an additional control method capable of detecting the amount of laundry before the execution unit 170 is input.

The laundry treatment apparatus of the present invention may be provided to sense the amount of laundry when a user selects a desired course or option from among a plurality of courses or options.

The expected execution time or the amount of detergent required by the user may be the execution time or amount of detergent for a course or option selected by the user. Therefore, when the user selects a course or option, the laundry treatment apparatus of the present invention may be provided to guide the expected execution time or amount of detergent corresponding to the course or option.

On the other hand, the time when the user inputs the course selection unit 140 and the option selection unit 160 is after the power supply unit 120 is input, and the door 13 is opened and closed to put clothes on the drum 30 . It is highly probable that it was after the time it was put in.

In other words, after the input of the course selection unit 140 and the option selection unit 160 , if the user is informed of the expected execution time or detergent amount according to the amount of clothing, the user places the clothing on the drum 30 . Regardless of whether it is a person who has a habit of inputting the power supply unit 120 after inputting, or a person who inputs the power supply unit 120 first and then puts clothes into the drum 30, the user is accurately informed of the expected execution time or amount of detergent. can guide you.

To this end, the laundry treatment apparatus of the present invention may perform the course input step C1 of detecting that the course selection unit 140 or the option selection unit 160 is input.

When the control unit P detects that the course selection unit 140 or the option selection unit 160 has been input, the control unit P may perform the laundry weight detection step C2 of detecting the laundry amount of the clothes.

When the laundry weight detection step C2 is performed, the control unit P controls at least any one of the laundry amount of the clothing, the expected execution time of the selected course or option corresponding to the laundry weight, and the amount of detergent for performing the course or option. An information display step (C3) of displaying one on the display unit 16 may be performed.

After the information display step (C3), the control unit (P) may perform the execution input step (C6) of detecting whether the user is input by the execution unit (170), and the user selects a course or option It is possible to perform the course setting step (C4) and the change display step (C5) by detecting whether or not to change.

The information display step (B3), the course setting step (C4), the change display step (C5), and the execution input step (C6) may be the same as in the above-described embodiment.

9 is a diagram illustrating a control method by which a user can change the execution time of a course or option in the laundry treatment apparatus of the present invention.

When receiving a command for selecting any one course or option by inputting the user selection unit 140 or 160, the control unit p of the laundry treatment apparatus of the present invention may predict an expectation of the selected course or option. The time may be displayed on the display unit 130 .

At this time, when the time adjusting unit 200 receiving a command to extend or reduce the execution time of the selected course or option is input, the control unit P extends or reduces the execution time of the selected course or option to extend or reduce the execution time of the selected course or option. Or it may be provided to carry out the option.

Of course, as for the execution time of the course or option, the minimum time (lower limit) for achieving the purpose of washing and the maximum time (upper limit) for preventing washing delay may be set. The control unit p may change the execution time of the course or option according to the input of the time adjusting unit 200 within the lower limit time and the upper limit time.

The upper limit time may be set to be less than three times the execution time of any course or option, and the lower limit time may be set to half the execution time of any course or option.

When the time control unit 200 is input, the control unit P may extend or reduce the execution time of at least one of the washing operation, the rinsing operation, and the dehydration operation performed in the selected course or option.

For example, the laundry treatment apparatus of the present invention performs the laundry weight detection step T1 of detecting the laundry amount of the clothing, and then receives a command for the user to select a course or option through the control panel 16 . A selection step T2 may be performed.

When any one course or option is selected, an expected display step T3 in which the execution time of the course or option corresponding to the laundry amount of the clothing is displayed may be performed.

In this case, when the execution time of the course or option displayed in the expected display step T3 is set to be shorter or longer than expected, the time changing step T4 in which the user can receive a command to change the execution time may be performed. When the time adjusting unit 200 is input, the control unit P may change the execution time of the course or option between an upper limit and a lower limit in the time changing step T4.

When the execution time of the course or option is extended or reduced in the time changing step T4, an input reflecting step T5 of changing the course or option execution time by reflecting this may be performed.

If the user is satisfied with the change in the execution time, the user may input the execution unit 170 to perform the washing cycle, the rinsing cycle, and the spin-drying cycle with the course or option. When the execution unit 170 is input, the control unit P may perform an execution input step T6 of performing a washing cycle, a rinsing cycle, and a spin-drying cycle with the selected course or option. .

On the other hand, when the execution unit 170 is input without the input of the time control unit 200 in the time changing step T4, the control unit P performs a washing cycle, a rinsing cycle, and a spin-drying cycle with the selected course or option. It is possible to perform the execution input step (T6) for performing the.

Meanwhile, when the execution time of the course or option selected in the input reflection step T5 is extended or reduced, the controller P may determine how to extend or reduce it.

The controller P may determine to extend or reduce the execution time of at least one of the washing cycle, the rinsing cycle, and the dehydration cycle performed in the selected course or option in the input reflection step T5.

10 shows an embodiment in which the control unit P extends and reduces the execution time of a course or option.

Referring to FIG. 10( a ), when the laundry treatment apparatus of the present invention is provided as a washing machine, any course or option includes a washing cycle of removing foreign substances from clothes with water and detergent, a rinsing cycle of washing and rinsing the clothes with water, and the clothes It may consist of a dehydration cycle to remove water from The original execution time of the course or option selected by the laundry treatment apparatus of the present invention may be defined as the reference time t1.

The washing cycle may be performed for a reference washing time tw, the rinsing cycle may be performed for a reference rinsing time tr, and the dehydration cycle may be performed for a reference dehydration time th.

When the execution time of the selected course or option is extended or reduced, the controller p may select and extend or shorten the execution time of one or more of the washing cycle, the rinsing cycle, and the dehydration cycle.

Specifically, the control unit p may extend or shorten the washing cycle, the rinsing cycle, and the dehydration cycle in proportion.

Referring to FIG. 10(b), the execution time extended from the execution time of the existing selected course or option may be defined as the extended time t2, and the difference between the extended time t2 and the reference time t1 is It can be defined as the extension time (te).

When the execution time is increased by the extension time te, it may be extended according to the ratio of the existing reference washing time tw, the reference rinsing time tr, and the reference dehydration time th.

Accordingly, the washing cycle may be performed for an extended washing time twe that is longer than the reference washing time tw, and the rinsing cycle is performed for an extended rinsing time tre longer than the reference washing time tr. The dehydration cycle may be performed for an extended dehydration time (the) longer than the reference dehydration time (th).

Referring to FIG. 10( c ), the execution time shortened from the execution time of the existing selected course or option can be defined as the shortened time t3 , and the difference between the reference time t1 and the shortened time t3 is It can be defined as the reduction time (ts).

When the execution time is shortened by the reduction time ts, it may be shortened according to the ratio of the existing reference washing time tw, the reference rinsing time tr, and the reference dehydration time th.

Accordingly, the washing cycle may be performed for a shortened washing time (tws) shorter than the reference washing time (tw), and the rinsing cycle may be performed for a shortened washing time (trs) shorter than the standard washing time (trs). , the dehydration cycle may be performed during a shortened dehydration time (ths) shorter than the reference dehydration time (th).

As a result, even if the execution time of the selected course or option is extended or reduced, the laundry treatment apparatus of the present invention can achieve the purpose of the original course or option by proportionally extending and reducing the washing cycle, rinsing cycle, and dehydration cycle.

11 shows another embodiment in which the control unit P extends and reduces the execution time of a course or option.

Referring to FIG. 11( a ), when the laundry treatment apparatus of the present invention is provided as a washing machine, any course or option includes a washing cycle of removing foreign substances from clothes with water and detergent, a rinsing cycle of washing and rinsing the clothes with water, and the clothes It may consist of a dehydration cycle to remove water from The original execution time of the course or option selected by the laundry treatment apparatus of the present invention may be defined as the reference time t1.

The washing cycle may be performed for a reference washing time tw, the rinsing cycle may be performed for a reference rinsing time tr, and the dehydration cycle may be performed for a reference dehydration time th.

In this case, when the execution time of the selected course or option is extended or reduced, the controller p may select and extend or shorten the execution time of one or more of the washing cycle, the rinsing cycle, and the dehydration cycle.

The control unit p may extend and shorten any one of the washing cycle, the rinsing cycle, and the dehydration cycle, or extend and shorten the rest except for any one.

Referring to FIG. 11(b), when the execution time of the course or option is extended, the control unit P adjusts the washing cycle by the extended time te to the extended washing time twe longer than the reference washing time tw. ) can be performed while The execution time of the rinsing operation or the dehydration operation may be maintained as it is.

In addition, if the execution time of the rinsing cycle is maintained, the number of times of the rinsing cycle is not increased, so that the amount of water can be saved.

If the duration of the dehydration cycle is maintained, the duration of the physical force applied to the clothes by the drum 30 can be reduced to prevent damage to the clothes.

Of course, in some cases, the execution time of the dehydration cycle may be increased, and the number of rinsing times or the rinsing time may be increased in the rinsing cycle.

Referring to FIG. 11( c ), when the execution time of the course or option is shortened, the control unit P may perform the washing cycle for a shortened washing time tws shorter than the reference washing time tw. . The execution time or number of times of the rinsing operation may be maintained as it is, or the execution time of the dehydration operation may be maintained as it is.

If the rinsing cycle time is maintained, the effect of separating foreign substances or detergents from the clothes may be maintained. In addition, the dehydration effect can be achieved as it is by maintaining the dehydration cycle time.

On the other hand, when a command to extend the execution time is input from the time adjusting unit 200, the control unit p may further extend the execution time of the rinsing cycle or increase the number of rinsing to further separate foreign substances and detergents from the clothes. can

Of course, in some cases, the execution time of the dehydration cycle may be shortened, and the dehydration time may be shortened in the dehydration cycle.

In addition, when the time adjusting unit 200 is input, the control unit p changes the rpm of the drum set in at least one of the washing cycle, the rinsing cycle, and the spin-drying cycle, or the washing cycle, the rinsing cycle, and the spin-drying cycle. In any one of the strokes, the rotation rate (actuation rate) of the drum may be varied.

12 shows an embodiment in which the control unit P reduces or extends the execution time of the washing cycle.

When the execution time is extended or shortened, the control method of FIG. 12 can be applied to both extending or shortening the execution time of the washing cycle in proportion to or extending the execution time of the washing cycle by specifying it.

Referring to FIG. 12( a ), in the washing cycle, the drum may be rotated at the washing speed, stopped, and then the drum may be rotated again at the washing speed.

By intermittently rotating the drum, it is possible to prevent the clothes from being twisted and washed evenly, and to provide sufficient physical force to the clothes by changing the rotating direction of the drum. In addition, it is possible to secure a time for the detergent and water to permeate into the clothes or for foreign substances to be separated together with the detergent.

A ratio of the driving time of the driving unit 9 to the total time in the entire washing cycle may be defined as the operating rate. The performance rate of the washing cycle performed in the selected course or option may be defined as, for example, 50%. That is, the ratio of the driving time and the stopping time of the driving unit 9 in the washing cycle may be the same.

The control unit p may change the operating rate when the execution time is changed in the washing cycle.

Referring to FIG. 12( b ), the execution time in the washing cycle may be extended. The control unit p may reduce the activation rate when the execution time of the washing cycle is extended. That is, it is possible to prevent excessive physical force from being applied to the clothes for a long time by lowering the ratio of the drum rotation time in the entire washing cycle execution time.

Meanwhile, the rpm of the drum may be maintained in the washing cycle. Accordingly, while the drum 30 rotates, sufficient physical force is transmitted to the clothes to separate foreign substances from the clothes.

Referring to FIG. 12(c), the execution time in the washing cycle can be shortened. The control unit p may increase the operating rate when the execution time of the washing cycle is shortened. That is, sufficient physical force can be transmitted to the clothes even in a shortened time by increasing the ratio of the rotating time of the drum 30 in the entire washing cycle execution time.

However, the control unit p may not increase the rpm of the drum even if the execution time of the washing cycle is shortened. Accordingly, it is possible to prevent the clothing from being damaged due to a physical force greater than or equal to the reference value being applied to the clothing.

13 shows an embodiment in which the control unit P reduces or extends the execution time of the dehydration cycle.

When the execution time is extended or shortened, the control method of FIG. 13 can be applied to both extending or shortening the execution time of the dehydration cycle in proportion to or extending the execution time of the dehydration cycle by specifying it.

When the dehydration cycle starts, the laundry treatment apparatus of the present invention senses the wet cloth amount (wo) through the laundry weight sensing step, etc., and performs the first dehydration step (I) in which the drum is raised to medium speed RPM to stop, and then the drum is decelerated or , the second dehydration step (II) of removing moisture from the clothes by raising the drum to the highest speed, high RPM, is performed. The total dehydration time may correspond to the reference dehydration time (th).

The control unit (p) decreases the rpm of the drum (30) in the dehydration cycle when a command to extend the execution time is input from the time control unit (200), and extends the dehydration time (th) longer than the reference dehydration time (th) During the), a further dehydration cycle can be performed. Accordingly, it is possible to prevent damage to the clothes by reducing the total amount of physical force applied to the clothes while extending the execution time.

Specifically, the control unit p may lower the rpm of the drum 30 to an extended rpm lower than the high-speed rpm in the second dehydration step (II). The extension rpm can be maintained higher than the medium speed rpm at which the garment separates from the inner wall of the drum. Therefore, even if the rpm of the drum is lowered, it is possible to transmit sufficient centrifugal force to remove water to the clothes.

On the other hand, the control unit P increases the rpm of the drum in the spin-drying cycle when a command to shorten the execution time is input from the time control unit 200, and shortens the dehydration time (ths) shorter than the reference spin-drying time (th). ) during the dehydration cycle. Accordingly, it is possible to shorten the execution time and maintain the dehydration effect while securing the centrifugal force applied to the clothes.

Specifically, the control unit p may increase the rpm of the drum 30 to a reduced rpm higher than the high-speed rpm in the second dehydration step (II).

Of course, unlike the above method, the control unit P may minimize the influence on the clothes by extending or reducing the duration of the first dehydration step (I).

14 is a diagram illustrating a method for controlling the weight sensing of the laundry treatment apparatus according to the present invention.

As described above, the laundry treatment apparatus of the present invention may perform the laundry weight sensing step of detecting the laundry weight of the clothes before the execution unit 170 is input. The laundry weight detection step described below may be performed in the laundry weight detection step described above.

The step of detecting the amount of laundry may include a rotating step (D1) of rotating the drum, and a calculation step (D3) of calculating the weight of the clothes by measuring a value of a first current applied or output in the rotating step (D3).

In the laundry treatment apparatus of the present invention, the drum 30 may be rotated by less than one rotation in the rotating step D1. Accordingly, the laundry treatment apparatus of the present invention can sense the amount of laundry before the drum 30 rotates one revolution.

For example, the weight detection step may be completed within 1 second. Therefore, before determining that the user inputs the power supply unit 120 , opens or closes the door 13 , selects the arbitrary course or option, and enters the execution unit 170 , the laundry amount of the clothing, or At least one of the expected execution time based on the laundry amount and the amount of detergent may be displayed on the display unit 17 .

Accordingly, the user can select or change a course or option and input the execution unit 170 while checking the expected execution time and detergent amount.

As a result, the laundry treatment apparatus of the present invention can guide the expected execution time or amount of detergent by quickly detecting the amount of laundry before the user finally decides to perform the course or option selected by the user.

In addition, it is possible to prevent the user from waiting for a long time to confirm the expected execution time of the selected course or option or the appropriate amount of detergent. As a result, washing delay can be prevented.

Meanwhile, in the step of detecting the amount of laundry, the rotating step (D1) is finished before the drum 30 makes one revolution. Accordingly, in the step of detecting the amount of laundry, a restoring step (D2) of returning the drum 30 back to its original position may be performed.

The calculation step (D3) may be performed when the process in which the rotating step (D1) is performed or the rotating step (D1) is finished, and is performed when both the rotating step (D1) and the restoring step (D2) are performed. can

The step of detecting the laundry weight may further include a display step (D4) of displaying the laundry amount of the clothes on the display unit (17) when the calculating step (D3) is completed.

In the display step (D4), only the laundry amount of the clothes may be displayed, the expected execution time of a specific course or option corresponding to the laundry weight may be displayed, and the required amount of detergent required to perform the course or option may be displayed. it might be

The laundry weight detection step may be performed before the execution unit 170 is input, but the same may also be performed in the additional detection step performed after the execution unit 170 is input.

That is, the same step of detecting the amount of laundry may be performed in both the step of detecting the amount of dry laundry for performing the washing cycle and the step of detecting the amount of wet cloth for performing the dehydration cycle. In addition, the step of detecting the amount of laundry may be performed in the step of checking whether the clothes are wet or dry.

15 is a view showing an aspect of the laundry weight detection of the laundry treatment apparatus of the present invention.

Referring to FIG. 15A , the clothes may be disposed on the bottom surface of the drum 30 due to their own weight.

Referring to FIG. 15( b ), when the laundry weight sensing step is performed and the rotating step D1 is performed, the drum 30 may rotate until one rotation is performed.

In the rotating step (D1), the drum 30 may be rotated up to an angle at which the clothes are separated from the inner wall of the drum or the arrangement is changed. Accordingly, it is possible to prevent unnecessary load or impact from being transmitted to the driving unit 9 while the position of the clothes is changed inside the drum 30 . Accordingly, the control unit P may accurately calculate the load of the clothes through the current value applied or output to the driving unit 9 .

For example, in the rotating step (D1), the drum may be rotated in a range of 0 degrees to 90 degrees or less.

However, as the rotation angle of the drum 30 is smaller, the time required for the controller P to detect the amount of the clothes may be shortened, and the error in detecting the weight of the clothes may be reduced. Therefore, in the rotating step (D1), it is preferable that the drum 30 is rotated in the range of 10 degrees to 45 degrees or less.

16 is a diagram illustrating a laundry amount sensing calculation method of the laundry treatment apparatus of the present invention.

16 (a) and 16 (b), when the weight sensing step is performed, the control unit P can rotate the drum 30 in less than one revolution through the rotating step D1. have. In the calculating step D3, the control unit P may calculate (process) the laundry amount of the clothes by measuring the current applied or output to the driving unit 9 in the rotating step D1.

The controller P may use the formula Te=Jdw/dt+Bw+mgrsinΘ to detect the laundry amount.

Te is a torque value applied to the driving unit 9 and corresponds to I (current value) X K (drive unit constant). That is, since the driving unit constant k is an intrinsic value of the driving unit 9 itself, the control unit P may calculate a torque value applied to the driving unit 9 when the current value I is sensed.

At this time, in the case of mgrsinΘ to sinΘ, as the rotation angle of the drum becomes smaller, it exponentially decreases, so it can be sufficiently neglected if it is between 15 degrees and 90 degrees or between 10 degrees and 45 degrees.

In addition, Bw is a friction torque, and when the drum 30 rotates, B becomes very small, so it can be neglected.

As a result, only the expression Te = Jdw/dt can be left. At this time, since dw/dt is the angular acceleration for rotating the drum, the control unit p may sense the angular acceleration when rotating the drum in the rotating step (d1). The angular acceleration can also be directly calculated through the current value applied to the driving unit 9 .

Therefore, when the current value is measured, since both the torque value Te and the angular acceleration dw/dt applied to the driving unit 9 can be calculated, the moment of inertia J can be calculated.

As a result, the laundry treatment apparatus of the present invention can detect the moment of inertia (J) and immediately sense the amount of laundry of the clothes.

17 is a diagram illustrating a process in which the laundry treatment apparatus of the present invention calculates the amount of laundry using the moment of inertia.

Data describing the relationship between the moment of inertia and the laundry amount may be stored in the storage unit P2 .

When the weight of the clothing is determined, a moment of inertia generated when the clothing rotates on the drum 30 can be detected, and when the moment of inertia is determined, the weight of the clothing can be detected.

For example, if the control unit P detects the moment of inertia as 55000 in the calculation step D3, when the drum 30 is rotated counterclockwise, the amount of laundry can be determined as 2 kg, When the drum 30 is rotated clockwise, it can be determined as 3 kg.

In this way, the control unit p calculates the moment of inertia stored in the storage unit p2 and the weight of the clothes based on the diameter of the drum 30 and the rotation direction of the drum 30, and the like, through the data of the clothes. The amount of laundry can be detected immediately.

As a result, the control unit P can sense the amount of clothes in the clothes by sensing only the current applied or output in the rotating step D1. That is, the operation step D3 may be performed while the rotation step D1 is being performed or the moment the rotation step D1 ends.

As a result, the rotation step (D1) and the operation step (D3) can be all performed before the position of the drum 30 is restored to its original position. That is, the operation step (D3) may be already completed before the restoration step (D2) is finished.

As a result, the rotating step D1 and the calculating step D3 can all be performed within 0.3 seconds to 1 second, and the laundry weight detection step itself can be performed within 0.3 seconds to 1 second.

Therefore, the control unit P can detect the amount of laundry so quickly that the user hardly feels the time for detecting the weight, and guide the execution time of the selected course or option.

Meanwhile, when the laundry amount is detected in the calculation step D3, the control unit P may calculate and display the execution time or detergent amount of a course or option corresponding to the laundry amount almost simultaneously.

As a result, the rotating step (D1), the calculating step (D3), and the displaying step (D4) can all be performed before the position of the drum is restored.

Therefore, the rotating step D1, the calculating step D3, and the displaying step D4 can all be performed within 0.3 seconds to 1 second.

The present invention may be modified and implemented in various forms, but the scope of the rights is not limited to the above-described embodiments. Therefore, if the modified embodiment includes the elements of the claims of the present invention, it should be regarded as belonging to the scope of the present invention.
