Description

Clothes treatment apparatus and method of controlling the laundry treatment apparatus

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.

It can guide the expected execution time or changed execution time, required amount of detergent or changed amount of detergent.

Fig. 10 shows another expanded embodiment of Fig. 8;

In the laundry treatment apparatus of the present invention, the history of opening and closing of the door 13 may be stored in the storage unit P2. That is, in the laundry treatment apparatus of the present invention, even when the power supply unit 120 is not input, power is supplied to the control panel 16 or the storage unit P2 through standby power, so that the door 13 is opened and closed. This can be saved.

Therefore, in the laundry treatment apparatus of the present invention, if the door 13 is opened and closed even before the power supply unit 120 is input, the history storage step (B11) of storing the opening/closing history of the door 13 in the storage unit P2 is performed. can be done

Then, in the laundry treatment apparatus of the present invention, when the power input step B0 in which the power supply unit 120 is input and power is supplied to the control unit P is performed, the control unit P performs the laundry weight detection step B2. can

Accordingly, the laundry treatment apparatus of the present invention can help the user to select an optimal course and option or detergent amount before inputting the execution unit 170 .

Fig. 11 shows another expanded embodiment of Fig. 8;

In the laundry treatment apparatus of the present invention, when the opening/closing of the door is sensed in the opening/closing step (B1), the laundry weight sensing step (B2) may be performed.

In this case, the control unit P may also perform the clothes detection step B2-1 of detecting whether the clothes are accommodated in the drum 30 . If there are clothes in the drum 30 in the clothes detecting step (B2-1), the above-described control method may be performed as it is.

However, if the clothes are not accommodated in the drum 30 , the control unit P may perform the door opening/closing detection step B2-2 of waiting until the door 13 is opened and closed. That is, when the control unit P does not detect the amount of the clothes, the controller P may wait until the opening or closing of the door is sensed.

At this time, when the door opening/closing detection step B2-2 is performed, the controller P may perform the laundry weight detection step B2 again to additionally detect the laundry amount of the clothes.

Accordingly, when the door 30 is opened and the door 30 is opened and the clothes are put into the drum 30, the laundry treatment apparatus of the present invention can immediately sense the amount of the clothes. Accordingly, it is possible to quickly guide the expected execution time or the required amount of detergent for the course or option to be selected by the user before input to the execution unit 170 .

Also, when the clothes are not accommodated in the drum 30 even when the door 30 is opened or closed, the laundry treatment apparatus of the present invention waits for the clothes to be put into the drum 30 and detects the amount of the clothes. can do. Even if opening and closing of the door 30 is an essential condition for detecting the amount of clothes, the amount of clothes can be accurately detected after the time when the clothes are accommodated in the drum 30 .

12 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.

13 shows a further embodiment of a method for controlling a laundry treatment apparatus of the present invention.

The laundry treatment apparatus of the present invention may be configured to additionally detect the laundry weight even after the execution unit 120 is input after the laundry weight is sensed and the course or option is executed.

Accordingly, in the laundry treatment apparatus of the present invention, whether the amount of the laundry is too large to perform the course or option, or the weight of the clothing is excessively measured because the clothing is in a wet state (paste), so that the estimated execution time or the amount of detergent is excessive. You can check whether or not it is marked.

As a result, the laundry treatment apparatus of the present invention not only quickly senses the amount of clothes, but also accurately detects the state of the clothes after that, so that an optimal course or option can be performed.

Referring to FIG. 13(a), in the laundry treatment apparatus of the present invention, the power input step (E1) in which the power supply unit 120 is input and power is supplied, and the opening/closing step (E2) of sensing the opening and closing of the door 13 (E2) And, when the power supply unit 120 inputs and the door 13 is opened and closed, the laundry weight detection step E3 of detecting the laundry amount of the clothing, and the execution time or necessity of a course or option corresponding to the laundry weight of the clothing An information display step E4 of displaying the detergent amount on the display unit 16 may be performed.

Thereafter, when the course setting step (E5) in which the user sets a desired course or option by inputting at least one of the course selection unit 140 and the option selection unit 160 is performed, the execution time of the changed course or option or A change display step (E6) of displaying the required amount of detergent may be performed.

When a desired course or option is confirmed by the user in the information display step E4 or the change display step E6, the execution unit 170 is input and the execution input step E7 in which the course or option is executed may be performed. have.

When the course or option is performed, the door 13 may be locked to the cabinet 10 .

The laundry treatment apparatus of the present invention may perform an additional sensing step (E9) of additionally checking the state of the clothes when there is no risk of water, detergent, or clothes being discharged through the door 13 .

The control unit P may perform a final display step E10 of immediately notifying the user of changes in the laundry amount, expected execution time, and required detergent amount of the clothes through the additional detection step E9.

As a result, when a situation change occurs in the information guided to the user in the information display step E4 , the control method corresponding thereto can be modified, and the user can be informed.

As a result, a course or option may be performed more suitable for clothes, and the user may be guided to a changed situation to induce an appropriate response of the user.

For example, in the additional detection step E9 , when the laundry amount value of the clothing is greater than a reference value for performing a course or option, the control unit P provides a course to the user in the final display step E10 . Alternatively, instructions for stopping the execution of the option and partially withdrawing clothes may be displayed on the display unit 16 .

In addition, if the control unit P detects that the clothing is overweight because it is a wet cloth in the additional detection step E9, the estimated execution time or The remaining time may be corrected or the required amount of detergent may be corrected and displayed.

When the execution unit 170 is input, the control unit P may additionally sense the amount of clothes to be worn and recalculate the expected time of the arbitrary course or option.

14 is a diagram illustrating a control method by which the clothes treatment apparatus of the present invention can detect whether clothes are wet or dry in the additional sensing step E9.

When the additional detection step (E9) is performed, the laundry treatment apparatus of the present invention may perform a water supply step (E91) of opening the water supply valve (72), and during or after the water supply step (E91) is completed, the clothes A compress detection step E91 of detecting whether or not was initially a compress may be performed.

The water supply step (E91) may supply enough water to perform the course or option.

In addition, in the water supply step ( E91 ), when it is expected that the clothes are raisins, only a small amount that the clothes can hold water is supplied. For example, when the clothes are raisins, the water supplying step E91 may be to supply only water to the extent that the water level does not rise.

At this time, when the water level of the tub 20 is higher than the expected water level after the water supply step E91 is completed, the control unit P may determine that the clothing is not a dry cloth but a wet cloth containing a certain moisture. .

When the clothes are wet cloths, the actual weight of the clothes may be less than the weight of the clothes detected in the laundry weight sensing step E3 by the amount of water absorbed by the clothes.

Accordingly, the control unit P may calculate the weight obtained by subtracting the amount of moisture from the weight of the clothes, or may calculate the weight of the clothes at a washing water level at which washing can be performed.

Accordingly, the control unit P may change the execution time of the course or option or the amount of detergent in anticipation of the weight when the clothing is dry cloth, and display it in the final display step E10.

In other words, when the execution unit 170 is input, the control unit P drives the lock unit and temporarily drives the water supply unit 70 , and then detects the laundry amount of the clothing additionally to detect the optional course or option. It is possible to recalculate the estimated time of

On the other hand, the laundry weight detection step may be performed to start a course or option before water is supplied to the tub 20 , and after water is drained into the tub 20 , dehydration is performed to perform a dehydration cycle. It may be performed to detect the amount of laundry.

15 is a diagram illustrating a control method by which the clothes treatment apparatus of the present invention can detect whether the clothes are wet or dry in the additional sensing step (E9).

Referring to FIG. 15A , when the additional sensing step E9 is performed, the laundry treatment apparatus of the present invention may perform a rotating step E9A of rotating the drum to determine the state of the clothes, and the rotation Upon completion or during the process of step E9A, a wet width detection step E9B of detecting whether the garment was initially a wet cloth may be performed.

The rotating step (E9A) may be a step of continuously rotating the drum one or more revolutions.

The control unit p may detect whether the clothes are wet by using a current value applied or output to the driving unit 9 in the rotating step.

Fig. 15(b) shows the difference between a wet cloth and a dry cloth on the drum 30.

The figure on the left shows a case in which the clothes such as dry towels are dry cloth, and the figure on the right shows a case where the clothes such as wet towels are wet cloths.

When the wet clothes and dry clothes have the same weight (eg, 5 kg), the current values of the driving unit 9 for rotating the drum 30 may not differ significantly. However, in the case of the wet cloth, the contact force is better than that of the dry cloth, and therefore, each time the drum rotates, a large amount of clothing can fall to the inner wall of the drum at the same time. As a result, the vibration value of the clothes in the wet fabric is greater than the clothes in the dry fabric can be sensed.

Accordingly, when the vibration value generated by the drum 30 is greater than or equal to the reference value or a one-time vibration waveform is generated according to one rotation, the control unit P may detect that the clothing is a wet cloth.

16 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.

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

Referring to FIG. 17A , the clothes may be disposed on the bottom surface of the drum 30 due to their own weight.

Referring to FIG. 17( 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.

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

18(a) and 18(b), when the weight sensing step is performed, the control unit P can rotate the drum 30 by 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.

19 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.

As described above, since the conventional laundry treatment apparatus detects the amount of laundry after the course or option is executed, the user cannot recognize the amount of laundry until the user selects the course or option and executes the course or option.

In addition, since the conventional laundry treatment apparatus rotates the drum by at least one revolution when sensing the laundry weight, the laundry weight detection cannot be performed quickly.

Therefore, in the case of the conventional laundry treatment apparatus, since the user does not recognize the amount of laundry before executing the course or option, there is no room for administering a detergent suitable for this, and thus, an excessive amount of detergent is input to ensure washing performance. This not only wastes detergent, but also damages the health as residual detergent remains on the clothes and causes environmental pollution.

In addition, in the case of the conventional laundry treatment apparatus, since the user leaves the laundry treatment apparatus without waiting until the amount of laundry is sensed after executing the course or option, the user cannot check the execution time or the end time of the course or option.

Accordingly, the user has to frequently visit the laundry treatment apparatus to confirm the end of the course or option. In addition, in the conventional clothes treatment apparatus, the clothes are left in the drum for a long time even after the course or option is finished, causing the clothes to wrinkle or, in severe cases, the clothes can also be spoiled.

Furthermore, since the conventional laundry treatment apparatus locks the door when a course or option is executed, there is no possibility for the user to adjust the amount of laundry thereafter.

However, the laundry treatment apparatus of the present invention may detect and display the amount of laundry before the course or option is executed.

Accordingly, the user may recognize the amount of laundry before executing the course or option, and may input the detergent in consideration of the appropriate amount of detergent corresponding thereto. For example, the user may check the amount of detergent corresponding to the amount of laundry displayed on the detergent box, and then put the checked detergent into the laundry treatment apparatus.

As a result, the laundry treatment apparatus of the present invention can save the amount of detergent, solve the problem of excessive detergent remaining on the clothes after the course ends, and prevent environmental pollution.

In addition, since the laundry treatment apparatus of the present invention senses the amount of laundry by rotating the drum less than one revolution, even if the amount of laundry is sensed before executing a course or option, laundry delay or the like does not occur and user inconvenience is not caused.

For example, the laundry treatment apparatus of the present invention detects and displays the amount of laundry within 3 seconds when the power supply is input or the door is opened or closed due to the input of clothes, so that laundry delay is not caused.

Also, the laundry treatment apparatus of the present invention may detect a laundry amount before executing a course or option, and display an expected time or end time of the course or option corresponding to the laundry amount.

Accordingly, in the process of the user selecting any one course or option among any course or option, the expected time or end time of each course or option may be recognized. In this way, the user can select a course or option that fits the current schedule.

In addition, the user may recognize the expected time or end time of the course or option before executing the course or option. Accordingly, since the user checks the expected time or the end time and executes the course or option, the trouble of checking the laundry treatment apparatus before the end of the course or option can be reduced. Furthermore, the user can recognize the end time of the course or option, so that it is possible to prevent clothes from being left in the drum after the course is finished in advance.

In addition, since the laundry treatment apparatus of the present invention does not lock the door before executing the course or option, the laundry amount before locking the door is detected and displayed. Accordingly, the user may check the displayed amount of laundry to put more clothes in or take out clothes.

For example, if the user determines that the amount of laundry is too much to perform a specific course or option, he/she may take out some clothes to prevent the clothes processing apparatus from being stopped due to eccentricity and excessive vibration in the future.

For example, when the user confirms that the clothing has a large volume but has a small weight, it is possible to prevent the contaminated clothing from being left unattended for a long time by adding more clothing.

As such, the laundry treatment apparatus of the present invention quickly detects the amount of laundry, unlike the conventional laundry treatment apparatus, and displays the laundry amount or expected execution time before executing a course or option or before locking the door, thereby deriving the above-mentioned remarkable effect. can do.

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.
