Description

{A laundry treating apparatus and a control method of the same}

The present invention relates to a clothing treatment device and a control method thereof. More specifically, it relates to an interface that allows a clothing processing device and a user to communicate with each other and a method of utilizing it.

In general, a clothing processing device refers to a device that can wash or dry clothes, etc., or perform washing or drying. Here, the clothing processing device may perform only washing or drying functions, or may perform both washing and drying.

This clothing processing device is equipped with an arbitrary course or option for washing or drying clothing, and the execution time of the course or option is calculated based on the weight of the clothing. For example, if the amount of clothing is large, the execution time will be set to be relatively long, and if the amount of clothing is small, the execution time will be set to be relatively small.

Figure 1 shows a control method for executing an arbitrary course or option of a conventional clothing treatment device. (Refer to Korea Publication Patent Nos. 10-2009-0077097 and 10-2008-0102611, etc.)

Figure 1(a) shows a control method by which a conventional clothing treatment device performs an arbitrary course or option.

Referring to Figure 1 (a), the conventional laundry treatment device includes a power supply step (s1) in which power is supplied to the laundry treatment device by turning on the power button, and an appropriate course or option is selected on the control panel of the laundry treatment device. It may include a selection step (s2) in which a selection is made, and a start step (s3) in which an action button is inputted to execute the course or option.

In the case where the conventional clothing processing device is equipped with a front load type washing machine that has an opening through which clothes are put in the front of the cabinet, when the starting step (s3) is performed, a door lock secures the opening to the cabinet. Step s4 may be performed.

Thereafter, the conventional clothing processing device performs a laundry weight detection step (S5) in which the weight of the clothing is detected through a current value applied while rotating a drum containing the clothing. When the weight of the clothing is calculated, the control unit of the conventional clothing processing device performs a time display step (S6) of displaying the expected execution time of the selected course or option to the user, and an execution step of automatically executing the course or option. Perform (S7).

However, the laundry weight detection step (S5) and the time display step (S6) of a conventional clothing treatment device are performed after the start step (S3) in which the user executes a course or option. Therefore, there was a problem in which the user was forced to input the execution of the course or option without receiving information about the amount of clothing or the expected execution time.

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

Furthermore, the conventional clothing processing device does not allow the user to take active actions such as adding or reducing clothing, even if the execution time displayed in the time display step (s6) does not match the user's current intention or situation. There was a problem.

In addition, in conventional clothing processing devices, even if the execution time of the selected course or option does not meet the intention, the course or option cannot be canceled or changed unless active measures are taken, such as arbitrarily turning off the power of the washing machine to change it. There was a problem that couldn't be resolved.

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

Figure 1(b) shows the rotation state of the drum when a conventional laundry treatment device detects the amount of laundry.

Referring to FIG. 1(b), the conventional clothing treatment device rotates the drum D in the I direction to detect the weight of the clothing L.

Specifically, the conventional clothing processing device calculates the weight of clothing (L) by rotating the drum (D) in direction I and measuring the current value applied or output to the driving unit that rotates the drum.

In a conventional clothing processing device, when the drum (D) is rotated to detect the amount of laundry, the clothing (L) on the bottom of the drum rises inside the drum (D) and then falls in direction II due to gravity, thereby falling on the inner wall of the drum. It has no choice but to be separated from.

Accordingly, the conventional clothing treatment apparatus had a limitation in that in order to accurately detect the weight of the clothing L, the drum D had to be rotated continuously in the I direction for one or more rotations while aligning the current values applied or output.

As a result, the conventional clothing processing device had a problem in that it inevitably required more time to detect the amount of clothing than the time to continuously rotate the drum.

In addition, since the time required for the laundry weight detection step (S5) in the conventional clothing processing device is set to be relatively long, there is a problem in that the time display step (S6) that displays the execution time of the course or option cannot be quickly guided to the user.

Furthermore, the conventional clothing processing device detects laundry weight only after the start step (s3), in which the user selects a course or option and inputs an execution button, is performed.

As a result, there was a limitation in that the user could not check the laundry weight in advance and select a course or option, and in most cases, the user had already left the clothing treatment device when the laundry weight was detected.

Therefore, conventional clothing processing devices had a fundamental problem in that users could not check or actively use information about laundry weight.

Meanwhile, since conventional clothing processing devices perform laundry weight detection only when a course is performed, laundry weight detection is automatically performed even when the course is stopped, changed, and restarted. Conventional clothing treatment devices have a problem in that even though there is no change in the amount of laundry unless the door is opened or closed, the amount of laundry is automatically detected due to the course change, resulting in high energy consumption and a delay in washing.

Additionally, conventional clothing processing devices are equipped to turn off the power when a course is completed. If the user re-applies the power and performs a certain course to reprocess the clothes without opening or closing the door, the conventional clothes processing apparatus performs the laundry weight detection again, resulting in a washing delay.

The present invention aims to solve the problem of providing a clothing processing device that can immediately perform a new course by omitting laundry weight detection when changing a course during a course.

The present invention aims to solve the problem of providing a clothing treatment device that can continuously utilize previous weight information if the door is not opened or closed when the power supply is stopped after the end of the course and the power supply is performed again.

In order to solve the above-described problems, the present invention provides a clothing treatment device that omits the process of detecting the amount of laundry if there is no opening or closing of the door and there is a history of detecting the amount of existing laundry.

Since there is no change in the amount of laundry if the door is not opened or closed, the process of detecting the amount of laundry can be omitted even if the course is changed or the course is interrupted and re-run.

As a result, if there is no opening or closing of the door, the step of rotating the drum before performing the course or before supplying water can be omitted.

In addition, in order to solve the above-described problem, the laundry treatment apparatus of the present invention can be equipped to utilize the existing laundry volume as is, even if the power is turned off and then turned on again, if the door is not opened or closed.

The existing laundry weight value can be stored in a storage unit, and the storage unit utilizes standby power or is provided as an inactive memory to store the existing laundry weight as is unless a new laundry weight is updated.

Therefore, even if a course is selected and executed when the power is turned on from OFF, the process of re-detecting the weight can be omitted.

Figure 10 shows how the laundry treatment apparatus of the present invention detects the amount of laundry based on the above-described configuration.

The laundry treatment device of the present invention can detect the weight of laundry before input to the execution unit 740.

Specifically, the laundry treatment device of the present invention can detect the weight of the clothing by rotating the drum 3 when the power unit 710 is input or the opening or closing of the door 14 is detected.

In addition, when clothing is put into the drum 3 and vibration, etc. is transmitted to the driving unit 80, the drum 3 can be immediately rotated less than one revolution to detect the weight of the clothing.

As a result, since the drum 3 is rotated less than one revolution, the amount of laundry can be detected without the possibility of the user being injured or the clothing being damaged even if the user puts in clothing with the door 132 open.

Therefore, before selecting a course or option with the course selection unit 720 or before executing the course or option with the execution unit 740, the amount of laundry can be detected, and an appropriate amount of detergent can be recommended or a suitable course can be recommended. , the user can immediately display the expected execution time or completion time of the course while looking directly at the display unit 800.

As a result, the user can be encouraged to increase the utilization of the clothing processing device, and the user can be accurately informed of the time of collection of clothing.

Of course, the laundry treatment apparatus of the present invention may be equipped with a load sensor in the tub 2, the drum 3, or the drive unit 80 to directly detect the weight of the clothes.

Hereinafter, an embodiment of the laundry treatment apparatus of the present invention that detects the amount of laundry through rotation of the drum 3 will be described.

Referring to Figure 10(a), the clothing may be placed on the bottom surface of the drum 3 due to its own weight.

Referring to Figure 10(b), when detecting the amount of laundry, the laundry treatment device of the present invention can rotate the drum 3 less than one revolution.

That is, the laundry treatment apparatus of the present invention can rotate the drum 3 up to an angle at which the clothes are separated from the inner wall of the drum or their arrangement is changed. As a result, unnecessary load or shock can be prevented from being transmitted to the driving unit 32 while the position of the clothes inside the drum 3 is changed.

As a result, the laundry treatment device of the present invention can accurately transmit the current value applied or output to the driving unit 32 to the control unit C and accurately calculate the amount of laundry.

For example, the laundry treatment apparatus of the present invention can rotate the drum in a range of 0 degrees to 90 degrees or less when detecting the amount of laundry.

Meanwhile, the smaller the angle at which the drum 3 is rotated, the shorter the time it takes for the control unit C to detect the weight of the clothing, and the less error in detecting the weight of the clothing can be reduced.

Therefore, the laundry treatment apparatus of the present invention can rotate the drum 3 in a range of 10 degrees to 45 degrees or less when detecting the amount of laundry.

As a result, the laundry treatment device of the present invention can quickly and accurately detect the amount of laundry.

Accordingly, when the laundry treatment device of the present invention detects the opening or closing of the power unit 710 or the door 14 before the input of the execution unit 740, it can immediately detect the weight of laundry and display information related to the laundry weight on the display unit 800.

Figure 11 shows the laundry weight detection calculation method of the laundry treatment device of the present invention.

Referring to Figures 11(a) and 11(b), the control unit (C) can rotate the drum 3 in less than one revolution, and in the process, the current applied or output to the driving unit 32 Values can be measured.

The control unit (C) can calculate (process) the weight of the clothing based on the current value.

Specifically, the control unit C may use the formula Te=Jdw/dt+Bw+mgrsinΘ to detect the weight of laundry.

Te is the torque value applied to the driving unit 32 and corresponds to I (current value)

That is, since the driving unit constant (k) is a unique value of the driving unit 32 itself, the control unit (C) can calculate the torque value applied to the driving unit 32 when it senses the current value (I).

At this time, in the case of sinΘ in the mgrsinΘ, the value decreases exponentially as the rotation angle of the drum decreases. Therefore, if the rotation angle is between 15 degrees and 90 degrees or between 10 degrees and 45 degrees, sinΘ is sufficient. It can be ignored.

Additionally, Bw is a friction torque and can be ignored because B becomes very small when the drum 3 rotates.

As a result, only the formula Te = Jdw/dt remains.

At this time, dw/dt is the angular acceleration that rotates the drum, so the control unit (C) can detect the angular acceleration in the process of rotating the drum when detecting the amount of laundry. The angular acceleration can be directly calculated through the current value applied to the driving unit 32. A method of calculating the angular acceleration with the current value will be described later.

Therefore, by measuring the current value, both the torque value (Te) and the angular acceleration (dw/dt) applied to the drive unit 32 can be calculated, so the moment of inertia (J) can be calculated.

As a result, the clothing handling device of the present invention can determine the moment of inertia (J) and immediately detect the weight of the clothing through this.

Figure 12 shows the basic structure by which the control unit (C) can measure the current value of the driving unit 32 in the laundry treatment apparatus of the present invention.

Referring to FIG. 12(a), the control unit C controls the driving unit 32 by applying current to the driving unit 32 and can even detect the current discharged from the driving unit 32.

The control unit (C) controls the driving unit 32 according to a preset course or option, and the driving unit 32 rotates the drum 3 according to commands from the control unit (C).

The control unit (C) operates by receiving operation signals or control commands from the course selection unit 720, execution unit 740, or option selection unit 730. A washing course and option for performing washing, rinsing, and dehydration processes can be selected using the course selection unit 720 or the option selection unit 730.

Accordingly, washing, rinsing, and dehydration operations can be performed. Additionally, the control unit C can control the display unit 800 to display the washing course, washing time, spin-drying time, rinsing time, etc., or the current operating state.

The control unit (C) not only rotates the drum 3 by controlling the driving unit 32, but also can vary the rotation speed of the drum 3. Specifically, the control unit (C) is based on at least one of a current detection unit 225 that detects the output current flowing in the driver 32 and a position detection unit 220 that detects the position of the driver 320. The driving unit 32 can be controlled. For example, either the current detected by the driver 32 or the detected position signal may be fed back to the controller C, and the controller C adjusts the driver 32 appropriately according to the feedback signal. It is possible to generate a current signal that can be easily controlled.

Meanwhile, the laundry treatment device of the present invention omits the position detection unit 235 and can detect the position of the drive unit 32 through implementation of a separate algorithm. (aka, sensorless driving unit) The sensorless driving unit 32 allows the control unit C to determine the position of the rotor or stator in the driving unit 32 by measuring the current or voltage output from the driving unit 32. It can be provided.

Below, an embodiment in which the control unit C controls the driving unit 32 will be described.

The driving unit (P) may be provided as a three-phase motor so that the rotation speed can be controlled, and may be provided as a BLDC motor, for example.

Referring to FIG. 12(b), the control unit C may include an inverter 420 and an inverter control unit 430 to control the rotor and stator described above. Additionally, the control unit C may further include a converter 410 that supplies direct current power input to the inverter 420.

That is, the control unit C can simultaneously perform the role of the inverter control unit 430. Of course, the inverter control unit 430 may be provided separately from the control unit (C). When the inverter control unit 430 outputs a pulse width modulation (PWM) switching control signal (Sic) to the inverter 420, the inverter 420 performs a high-speed switching operation and supplies AC power of a predetermined frequency to the rotor 913. ) and can be supplied to the stator (911).

The laundry treatment device of the present invention may further include a converter 410, an inverter 420, and an inverter control unit 430, as well as a DC voltage detection unit (B), a smoothing capacitor (C), and an output current detection unit (E). there is. In addition, the laundry treatment apparatus of the present invention may further include an input current detection unit (A), a reactor (L), etc.

The reactor (L) is disposed between the commercial AC power source (405, vs) and the converter (410) to perform power factor correction or boosting operations. Additionally, the reactor L may perform a function of limiting harmonic current caused by high-speed switching of the converter 410.

The input current detection unit (A) can detect the input current (is) input from the commercial AC power source 405. For this purpose, a CT (current trnasformer), shunt resistor, etc. may be used as the input current detection unit (A). The detected input current (is) is a discrete signal in the form of a pulse and can be input to the inverter control unit 430.

The converter 410 converts the commercial AC power 405 that has passed through the reactor L into direct current power and outputs it. In the drawing, the commercial AC power source 405 is shown as a single-phase AC power source, but it may also be a three-phase AC power source. The internal structure of the converter 410 also varies depending on the type of commercial AC power source 405.

Meanwhile, the converter 410 is composed of a diode, etc. without a switching element, and may perform a rectification operation without a separate switching operation. For example, in the case of a single-phase AC power source, four diodes can be used in a bridge form, and in the case of a three-phase AC power source, six diodes can be used in a bridge form.

The converter 410 may be a half-bridge type converter in which two switching elements and four diodes are connected, and in the case of three-phase AC power, six switching elements and six diodes may be used. When the converter 410 is provided with a switching element, a voltage boost operation, power factor improvement, and direct current power conversion can be performed by the switching operation of the corresponding switching element.

The smoothing capacitor (C) smoothes the input power and stores it. In the drawing, a single device is illustrated as a smoothing capacitor (C), but multiple devices may be provided to ensure device stability.

The converter 410 may be connected to the output terminal, but direct current power may also be input directly. For example, direct current power from a solar cell may be directly input to the smoothing capacitor (C) or may be input after being converted to direct current/direct current. Since direct current power is stored at both ends of the smoothing capacitor (C), it may also be called a dc end or dc link end.

The dc terminal voltage detector (B) can detect the dc terminal voltage (Vdc) at both ends of the smoothing capacitor (C). To this end, the DC terminal voltage detection unit (B) may include a resistor element, an amplifier, etc. The detected DC terminal voltage (Vdc) may be input to the inverter control unit 430 as a discrete signal in the form of a pulse.

The inverter 420 is provided with a plurality of inverter switching elements, and converts the smoothed direct current power (Vdc) into three-phase alternating current power (va, vb, vc) of a predetermined frequency by the on/off operation of the switching elements to drive the driving unit. It can be output at (32). The inverter 420 has a pair of upper arm switching elements (Sa, Sb, Sc) and lower arm switching elements (S'a, S'b, S'c) that are connected in series with each other, and a total of three pairs of upper and lower arm switching elements are provided. Switching elements can be connected in parallel (Sa&S'a, Sb&S'b, Sc&S'c).

A diode is connected to each switching element (Sa, S'a, Sb, S'b, Sc, S'c) in anti-parallel.

The switching elements in the inverter 420 perform on/off operations based on the inverter switching control signal (Sic) from the inverter control unit 430. As a result, three-phase AC power having a predetermined frequency is output to the driver 32.

The inverter control unit 430 can control the switching operation of the inverter 420. For this purpose, the inverter control unit 430 can receive the output current (io) detected by the output current detection unit (E).

The inverter control unit 430 outputs an inverter switching control signal (Sic) to the inverter 420 in order to control the switching operation of the inverter 420. The inverter switching control signal (Sic) is a pulse width modulation (PWM) switching control signal, which is generated and output based on the output current value (io) detected by the output current detector (E).

The control unit (C) can detect the state of the drum by detecting the output current value (io) detected by the current detection unit 220. In addition, the control unit (C) can detect the state of the inside of the drum based on the position signal (H) detected by the position detection unit (235). For example, while the drum 3 rotates, the laundry weight, dehydration rate, moisture content, etc. can be sensed based on the output current value io of the drive unit 32. Additionally, the control unit C may detect the amount of eccentricity of the drum 4, that is, the unbalance (UB) of the drum 3. This amount of eccentricity may be detected based on the ripple component of the current io detected by the current detector 220 or the change in rotational speed of the drum 4.

Additionally, the control unit (C) may detect the state of the drum by detecting the input current value (is) input to the inverter control unit. The process and calculation method for detecting the state inside the drum through the current value will be described later.

The output current detection unit (E) may be provided to detect the output current (io) flowing between the inverter 420 and the three-phase driver 32. The output current detection unit (E) detects the current flowing in the driving unit (32). The output current detection unit (E) can detect all output currents (ia, ib, ic) of each phase, and can also detect the output currents of two phases using three-phase balance.

The output current detection unit (E) may be located between the inverter 420 and the driving unit 32, and a current transformer (CT), a shunt resistor, etc. may be used to detect the current. When the shunt resistor is used, three shunt resistors are located between the inverter 420 and the driver 32, or the three lower arm switching elements (S'a, S'b, and S'c of the inverter 420) ) can be connected to each end.

On the other hand, using three-phase balance, it is also possible for two shunt resistors to be used. Additionally, when one shunt resistor is used, it is also possible for the shunt resistor to be disposed between the capacitor C described above and the inverter 420.

The detected output current (io) is a discrete signal in the form of a pulse and can be applied to the inverter control unit 430, and an inverter switching control signal (Sic) is generated based on the detected output current (io). do. Hereinafter, the detected output current (io) is described as the three-phase output current (ia, ib, ic).

Meanwhile, the three-phase drive unit 32 is equipped with a stator and a rotor, and AC power of each phase with a predetermined frequency is applied to the coil of the stator of each phase (phase a, b, and c), so that the rotor rotates. I do it.

This driving unit 32 is a surface-mounted permanent-magnet, synchronous motor (SMPMSM), an interior permanent magnet synchronous motor (IPMSM), and a synchronous reluctance motor (Synchronous motor). Reluctance Motor; Synrm), etc. Among these, SMPMSM and IPMSM are synchronous motors (Permanent Magnet Synchronous Motor (PMSM)) using permanent magnets, while Synrm is characterized by having no permanent magnets.

Meanwhile, when the converter 410 includes a switch element, the inverter control unit 430 can control the switching operation of the switching element within the converter 410. To this end, the inverter control unit 430 may receive the input current (is) detected by the input current detection unit (A). And, the inverter control unit 430 may output a converter switching control signal (Scc) to the converter 410 in order to control the switching operation of the converter 410. This converter switching control signal (Scc) is a pulse width modulation (PWM) type switching control signal, and can be generated and output based on the input current (is) detected by the input current detector (A).

Meanwhile, the position detection unit 235 can detect the rotor position of the driving unit 32. For this purpose, the position detection unit 235 may include a Hall sensor. The detected rotor position (H) is input to the inverter control unit 430 and used as a basis for speed calculation.

Figure 12(c) shows an example of a specific circuit structure in which the inverter control unit 430 controls the driving unit 32. The inverter control unit 430 includes an axis conversion unit 510, a speed calculation unit 520, a current command generator 530, a voltage command generator 540, an axis conversion unit 550, and a switching control signal output unit ( 560).

The axis conversion unit 510 receives the three-phase output current (ia, ib, ic) detected by the output current detection unit (E) and converts it into two-phase current (iα, iβ) in the stationary coordinate system. The axis conversion unit ( 510) can convert two-phase currents (iα, iβ) in a stationary coordinate system into two-phase currents (id, iq) in a rotating coordinate system.

The speed calculation unit 520 can calculate the speed based on the rotor position signal (H) input from the position detection unit 235. In other words, based on the position signal, the speed can be calculated by dividing it by time. The speed calculation unit 520 may output the calculated position and calculated speed based on the input rotor position signal (H).

The current command generator 530 has an operation speed ( ) and the speed command value (ω*r), generate the current command value (i*q). For example, the current command generator 530 has an operation speed ( ) and the speed command value (ω*r), the PI controller 535 performs PI control and generates a current command value (iq). In the drawing, the q-axis current command value (i*q) is exemplified as the current command value, but unlike the drawing, it is also possible to generate the d-axis current command value (i*d). Meanwhile, the value of the d-axis current command value (i*d) may be set to 0.

Meanwhile, the current command generator 530 may further include a limiter (not shown) that limits the level of the current command value (i*q) so that it does not exceed the allowable range. Next, the voltage command generator 540 generates the d-axis and q-axis currents (id, iq) converted to a two-phase rotation coordinate system in the axis conversion unit, and the current command value (i*) from the current command generator 530, etc. Based on d,i*q), d-axis and q-axis voltage command values (v*d,v*q) are generated. For example, the voltage command generator 540 performs PI control in the PI controller 544 based on the difference between the q-axis current (iq) and the q-axis current command value (i*q). A voltage setpoint (v*q) can be generated. In addition, the voltage command generator 540 performs PI control in the PI controller 548 based on the difference between the d-axis current (id) and the d-axis current command value (i*d), and the d-axis voltage command value (v*d) can be created. Meanwhile, the value of the d-axis voltage command value (v*d) may be set to 0, corresponding to the case where the value of the d-axis current command value (i*d) is set to 0.

Meanwhile, the voltage command generator 540 may further include a limiter (not shown) that limits the level of the d-axis and q-axis voltage command values (v*d, v*q) so that they do not exceed the allowable range. .

Meanwhile, the generated d-axis and q-axis voltage command values (v*d, v*q) are input to the axis conversion unit 550.

The axis conversion unit 550 is the position calculated by the speed calculation unit 520 ( ) and d-axis and q-axis voltage command values (v*d, v*q) are input, and axis conversion is performed. First, the axis conversion unit 550 performs conversion from a two-phase rotating coordinate system to a two-phase stationary coordinate system. At this time, the position calculated by the speed calculation unit 520 ( ) can be used.

Then, the axis conversion unit 550 performs conversion from a two-phase stationary coordinate system to a three-phase stationary coordinate system. Through this conversion, the axis conversion unit 1050 outputs three-phase output voltage command values (v*a, v*b, v*c).

The switching control signal output unit 560 generates a switching control signal (Sic) for the inverter according to the pulse width modulation (PWM) method based on the three-phase output voltage command values (v*a, v*b, v* c). and print it out.

The output inverter switching control signal Sic may be converted into a gate driving signal by a gate driver (not shown) and input to the gate of each switching element in the inverter 420. As a result, each switching element (Sa, S'a, Sb, S'b, Sc, S'c) in the inverter 420 performs a switching operation.

Meanwhile, in relation to the embodiment of the present invention, the switching control signal output unit 560 can generate and output an inverter switching control signal (Sic) that combines the two-phase pulse width modulation method and the three-phase pulse width modulation method. there is.

For example, in the accelerated rotation section described later, an inverter switching control signal (Sic) using a three-phase pulse width modulation method is generated and output, and in the constant speed rotation section, an inverter using a two-phase pulse width modulation method is used to detect back electromotive force. A switching control signal (Sic) can be generated and output.

Figure 13 shows an embodiment in which the control unit (C) detects the amount of laundry through acceleration and deceleration of the drum.

The laundry treatment apparatus of the present invention can perform a detection step (F) of detecting the amount of clothes inside the drum 3 before performing a washing cycle, before performing a rinsing cycle, and before performing a dehydration cycle.

To this end, the control unit (C) performs an acceleration step (F1) for accelerating the drum 3, a deceleration step (F2) for decelerating the drum 3, and acceleration of the driving unit 32 during the acceleration step. A laundry weight detection step (F3) of detecting the weight of clothing contained in the drum can be performed through the measured value and the deceleration measurement value of the driving unit during the deceleration step.

The laundry treatment device of the present invention detects an acceleration measurement value measured by or applied to the drive unit 32 while accelerating the drive unit 32, and decelerates the drive unit 32 to detect the acceleration value. It detects the deceleration measurement value measured in or applied to the driving unit 32. Thereafter, the acceleration measurement value and the deceleration measurement value are calculated to detect the amount of clothing contained in the drum 3.

The acceleration measurement value and the deceleration measurement value may be a command value applied to the driving unit 32 while driving the driving unit 32, or may be a measurement value measured in the driving unit 32 while driving the driving unit 32. there is.

For example, the command value may be a current command value or a voltage command value derived from the PI controller 535 applied to drive the driver 32, and the measured value may be a current command value or a voltage command value derived from the position detection unit 235 or the current It may be the current value or voltage value of the driving unit 32 measured by the sensing unit 225.

Accordingly, the laundry treatment apparatus of the present invention can significantly shorten the time required to detect the amount of laundry by omitting the step of maintaining the driving unit 32 at a constant speed.

In addition, the laundry treatment apparatus of the present invention can save not only the process of maintaining the driving unit 32 at a constant speed, but also the energy and time required to maintain the constant speed. In addition, the laundry treatment device of the present invention can completely ignore the frictional force of the driving unit 32 itself, which must be overcome when maintaining the driving unit 32 at a constant speed, in the calculation process.

When the control unit (C) uses the command value when detecting the amount of laundry, the control unit (C) feeds back the actual situation to the driving unit 32 or the actual driving situation of the driving unit 32. There is no need to consider . Therefore, it can be simple and easy for the control unit C to calculate the weight value. Additionally, since the calculation formula for calculating the weight of laundry is simplified, the weight value can be obtained quickly.

Specifically, the acceleration measurement value includes an acceleration current value (Iq_Acc) measured by the driver 32, and the deceleration measurement value may include a deceleration current value (Iq_Dec) measured by the driver 32. .

The acceleration current value includes a current command value (Iq*_Acc) for rotating the driver 32 during the acceleration phase, and the deceleration current value includes a current command value for rotating the driver 32 during the deceleration phase. May contain value (Iq*_Dec).

On the other hand, when the control unit (C) uses the measured value when detecting the laundry weight, the actual situation is reflected in the driving unit 32, so there is an advantage in that the laundry weight value can be accurately obtained.

In addition, the command value is generated only when the driver 32 is driven or powered and actively controlled. Therefore, using the measured value has the advantage of being able to obtain data for detecting the weight of laundry even when the power to the driving unit 32 is cut off or the driving unit 32 is not actively controlled.

The laundry treatment apparatus of the present invention can cut off the power in the deceleration step (F2) and decelerate the driving unit 32 using a power generation braking method or the like. Therefore, the algorithm for controlling the deceleration step (F2) can be omitted, and energy for the deceleration step (F2) can be saved.

Furthermore, since the power is cut off in the deceleration step (F2), the voltage command value may be O. Therefore, the present invention can detect the weight of laundry by calculating only current, excluding voltage.

In other words, the control method of the laundry treatment device of the present invention may ignore or not use the voltage command value or the voltage value itself, and only use the current value, so it is possible to provide a very simple calculation formula for detecting the weight of laundry. Because the calculation formula is simplified, the calculation can be done quickly and accurately, allowing the weight to be detected accurately.

Specifically, data and algorithms (hereinafter referred to as calculation formulas) for calculating the acceleration measurement value and the deceleration measurement value may be stored in the control unit (C). The above calculation formula can be prepared so as not to use voltage values from the beginning. Because of this, since there is no need to calculate the back electromotive force, the present invention can omit the constant speed rotation step of the driving unit 32.

For example, the calculation formula of the present invention may be provided as follows.

Weight value of the present invention (inertia, Jm, Load_data)

can be calculated in the following way. The P and Ke can be measured by the control unit (C) as constant values of the driving unit 32 itself, and the denominator corresponds to the difference between the speed change amount in the acceleration phase and the speed change amount in the deceleration phase.

The amount of change in speed can be measured by the control unit (C) by the position detection unit 235, calculated by measuring the time reached until the acceleration or deceleration, or immediately detected by measuring current, etc.

Therefore, the present invention can immediately calculate the weight value by simply measuring the acceleration output current value (Iq_Acc) when accelerating and the acceleration output current value (Iq_Dec) when decelerating. That is, the acceleration current value includes the acceleration output current value (Iq_Acc) output from the driver during the acceleration step, and the deceleration current value includes the deceleration output current value (Iq_Dec) output from the driver during the deceleration step. It can be seen that it does.

Furthermore, the acceleration output current value may be an average value (Iqe_Acc) of current values measured by the driver during the acceleration phase, and the deceleration output current value may be applied to the average value (Iqe_Dec) of current values measured by the driver during the deceleration phase. ) can be applied.

In any case, the laundry weight can be calculated with only one factor, the current value, and the voltage value factor can be omitted, thereby simplifying the laundry weight calculation and improving the speed and accuracy of the laundry weight value.

Accordingly, since the amount of laundry can be accurately detected even if the time of the acceleration step is very short, the time required to detect the amount of laundry can be further reduced.

Meanwhile, the laundry handling device of the present invention measures the weight of laundry by accelerating and immediately decelerating. Therefore, the time itself for measuring the amount of clothes is very short, and the clothes inside the drum 3 cannot move or flow during this time. Therefore, since the weight of the clothes can be detected in a short period of time while the state of the clothes does not change, the accuracy of the weight calculation can be further increased.

Meanwhile, the calculation formula applied to the weight detection of the present invention uses the difference between the current value in the acceleration phase and the current value in the deceleration phase. Therefore, the frictional force of the driving part in the acceleration stage and the frictional force of the driving part in the deceleration stage are equal to each other, so the current compensation equation considering the frictional force cancels each other. Therefore, since the laundry weight detection control method of the laundry treatment device of the present invention does not need to consider the friction force of the driving unit 32, the process of correcting or tuning the friction force can be omitted. In addition, since the laundry weight detection of the present invention does not use a voltage value, the process of compensating or tuning the error of the voltage value can be omitted, and since the constant speed process is omitted, the movement of clothing and the friction force of the driving unit 32 can be compensated or tuned. The process can be omitted. As a result, the laundry weight detection control method of the laundry treatment device of the present invention derives the laundry weight immediately by substituting the current value, and since there is no procedure for compensating or tuning the laundry weight, the laundry weight can be detected very quickly and accurately.

Accordingly, the load required for the control unit (C) can be reduced, the control unit (C) can be replaced with a relatively simple configuration, or the performance of the control unit (C) can be utilized in other ways.

Meanwhile, as can be seen from the above equation, the acceleration measurement value may further include the speed change amount of the acceleration step (F1), and the deceleration measurement value may further include the speed change amount of the deceleration step (F2).

The speed change amount of the acceleration step (F1) and the speed change amount of the deceleration step (F2) are only necessary to obtain the difference between the inertia of the acceleration step (F1) and the inertia of the deceleration step (F2), and separate voltage values, etc. There may be no need for measurement, and furthermore, no compensation or tuning process is needed.

In more detail, the above calculation formula is derived by the following calculation formula.

At this time, since the weight is calculated through the difference between acceleration inertia and deceleration inertia, the amount of change in the speed is necessary.

Therefore, if the acceleration measurement value and the deceleration measurement value are measured in the same RPM section of the drum, the amplitude of the speed change is the same, so the calculation can be simpler. That is, it is preferable that the acceleration step (F1) and the deceleration step (F2) share the same speed band.

Meanwhile, the control method of the laundry treatment device of the present invention performs an acceleration step (F1) and a deceleration step (F2) to detect the amount of laundry using a current command value or a current value measured by the driving unit 32.

At this time, since the above calculation formula uses the current value, the deceleration step (F2) is performed first, and the current value is measured by performing the acceleration step (Bb), and the weight of the laundry can be detected through the same calculation formula.

Meanwhile, the detection step (F3) involves performing a preparation step (F0) to check the position of the driving unit 32 to set a reference value for performing the acceleration step (F1) and the deceleration step (F2). You can. In the preparation step (F0), the drum 4 may be placed in a stationary state.

The acceleration step (F1) may additionally accelerate the drum stopped in the preparation step (FO) to the first rpm, and the deceleration step (F2) may decelerate the drum from the first rpm. That is, the acceleration step (F1) and the deceleration step (F2) can be performed continuously. The deceleration step (F2) is performed by lowering the current command value toward the driver 32 in the acceleration step (F1) or blocking the voltage applied to the driver 32, so there is a risk of damage to the control unit (C) or circuit. There is no

At this time, the acceleration measurement value and the deceleration measurement value may be measured between the first rpm and a second rpm lower than the first rpm. In other words, the amount of laundry can be detected by measuring the current value in the section band including the vertex in the speed graph. This has the advantage of minimizing situations where errors may occur because the amount of laundry is detected by measuring the current value in a continuous situation.

Meanwhile, the acceleration measurement value and the deceleration measurement value may be measured between a second rpm lower than the first rpm and a third rpm higher than the second rpm and lower than the first rpm. That is, although it is not a section including the vertex, the amount of laundry can be detected by measuring the current value in the same speed section band. This has the advantage of improving the accuracy of weight calculation by measuring the stabilized current value because the speed change is greatest at the vertex.

Meanwhile, the first rpm may be set to a lower rpm than the fixed rpm at which the clothes stored inside the drum 3 are attached to the inner wall of the drum 3. That is, the first rpm may be relatively lower than the rpm applied in the washing, rinsing, and dehydration processes.

In this case, the process of the control unit (C) directly calculating the moment of inertia or the process of comparing and extracting the moment of inertia with the clothing weight data stored in the storage unit (S) can be omitted.

The amount of current applied in the acceleration step (F1) can be defined as the first amount of current, and the amount of current applied in the deceleration step (F2) can be defined as the second amount of current. The control unit (C) can detect the amount of laundry through the first amount of current and the second amount of current.

Figure 14 shows an embodiment in which the laundry treatment apparatus of the present invention utilizes a laundry weight detection method based on the above-described structure and method.

Figure 14(a) shows an embodiment that basically utilizes the above-described weight detection method.

When the power supply unit 710 of the laundry treatment apparatus of the present invention is input, power can be supplied to the water supply unit 23, the drive unit 32, the drain unit 25, etc., and power can also be supplied to the control unit C. there is.

The control unit C may be set to detect the weight of the clothing when the power unit 710 is input and power is supplied.

That is, in the laundry treatment device of the present invention, an essential condition for detecting the amount of laundry may be the input of the power supply unit 710.

Therefore, even if the user opens the door 14 before inputting the power unit 710, puts clothes into the drum 3, and closes the door 14, the control unit C The weight of clothing can be detected immediately.

The control unit (C) can calculate the expected time to perform a specific course or option according to the weight of the clothing.

To this end, the control unit C can recognize the expected time corresponding to the weight of the clothing.

In addition, the control unit (C) may organize the amount of detergent required when performing a certain course or option on the amount of laundry in the clothing as data. The control unit (C) can calculate the amount of detergent required when washing the clothes using the course or option.

For example, the laundry treatment device of the present invention includes a power supply step (A1) in which power is supplied by inputting power to the power unit 710 of the laundry treatment device, and when the power supply step (A1) is performed, the drum 3 is supplied. A weight detection step (A2) can be performed to detect the weight of the received clothing.

In other words, the laundry treatment device of the present invention does not detect the weight of laundry only when the execution unit 740 receives input, but can detect the laundry weight before the execution unit 740 receives input.

When the weight of the clothing is detected in the laundry weight detection step (A2), at least one of the weight of the clothing, the expected execution time of the course or option for washing the clothing, and the amount of detergent required for the course or option is displayed on the display unit 800. The information display step (A3) can be performed in which one is displayed.

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

The user can check the amount of clothing displayed in the information display step (A3), the execution time of the preset course or option, and compare them with his or her schedule, and check the amount of detergent.

In other words, the laundry treatment apparatus of the present invention can check information related to laundry weight before entering the execution unit 740, select a desired course and option, and enter the execution unit 740. That is, if the user is satisfied with the information displayed in the information display step (A3), he or she can enter the execution unit 740. The control unit (C) may perform an execution input step (A6) in which the execution unit 740 detects input.

When the execution input step (A6) is performed, the control unit (C) controls the locking unit to lock the door 14 to the cabinet 10 to prevent the door 14 from being opened arbitrarily. there is.

When the execution input step (A6) is performed, the control unit (C) can perform one or more of the washing cycle, rinsing cycle, and spin-drying cycle according to the course or option settings.

However, in the information display step (A3), after the user confirms at least one of the weight of the clothing, the execution time of the preset course or option, and the amount of detergent, the course is selected through the course selection unit 720 and the option selection unit 730. A course setting step (A4) of selecting options may be further performed.

In other words, the user can select an arbitrary course or option rather than the standard course performed by default.

For example, the user can check the laundry weight of the clothing through the course setting step (A4) and then input one or more of the course selection section 720 and the option selection section 730, and the execution time associated with the laundry weight. After checking, you can change the course or option by entering one or more of the course selection section 720 and the option selection section 730.

When the course setting step (A4) is performed, the control unit (C) recalculates the expected execution time or detergent amount of the changed course or option corresponding to the weight of the clothing and transmits it to the display unit (P8) (change display step ( A5) can be performed.

In the change display step (A5), one or more of the expected execution time of the changed course or option and the changed detergent amount may be displayed on the display unit (P8).

If the user determines that the expected execution time or detergent amount is appropriate, the user can enter the execution unit 740, and if the expected execution time or detergent amount is not appropriate, the user can enter the course selection unit 720 and the option selection unit 730. You can re-enter one or more of the following.

The control unit (C) may perform an execution input step (A6) that detects an input from the execution unit (740).

However, if re-input of one or more of the course selection unit 720 and the option selection unit 730 is detected, the course setting step (A4) and the change display step (A5) can be performed again.

As a result, the laundry processing device of the present invention can complete laundry weight detection before the user selects and performs the final course and option. Moreover, by rotating the drum less than one revolution and calculating the weight of the laundry within 3 seconds, information about the weight of the laundry can be provided already before inputting one or more of the course selection unit 720 and the option selection unit 730.

For example, when the power unit 710 is input and the display unit 800 is booted, the laundry weight detection has already been completed and information corresponding to the laundry weight can be provided to the user.

Accordingly, the user can check the information on the amount of laundry, check the expected time of the most appropriate course and option at the current time, set the optimal course and option, or input the optimal amount of detergent.

Figure 14(b) shows an expanded embodiment of the control method of Figure 14(a).

When the laundry treatment device of the present invention receives a command from the power supply unit (P46), it operates at least one of the control unit (C), the driving unit (32), the water supply unit (23), the drain unit (25), and the control panel (16). A power input step (A1) that supplies power to can be performed.

When the power input step (A1) is performed, the laundry treatment device can perform a laundry weight detection step (A2) to detect the weight of the clothes.

The method of detecting the weight of laundry in the laundry weight detection step (A2) is to rotate the drum less than one revolution as described above.

At this time, the control unit (C) may also perform a clothing detection step (A2-1) to detect whether the clothing is accommodated in the drum (3). If there is clothing in the drum 3 in the clothing detection step (A2-1), the control method of FIG. 13(a) can be performed.

However, if the clothes are not accommodated in the drum 3, the control unit C may perform a door opening/closing detection step A2-2 of waiting until the door 132 opens and closes.

That is, if the control unit C does not detect the weight of the clothing, it may wait until it detects the opening or closing of the door.

At this time, when the door opening/closing detection step (A2-2) is performed, the controller (C) can perform the laundry weight detection step (A2) again to additionally detect the weight of the clothing.

As a result, the laundry treatment device of the present invention can immediately detect the amount of laundry when clothes are stored in the drum 3 before the power supply 710 is input. However, if no clothing is accommodated in the drum 3 before inputting the power unit 710, the weight of the clothing can be detected by waiting until the clothing is put into the drum 3.

In other words, the laundry treatment apparatus of the present invention can, in principle, immediately perform laundry weight detection when the power unit 710 is input and power is supplied to the control unit C.

Therefore, if the user first puts clothes into the drum 3 and inputs the power supply P46 before inputting the power supply unit 710, the control unit C can detect the weight of the clothes.

However, if there is no clothing inside the drum 3 before the power unit 710 is input, the control unit C waits for the door to be opened and closed to perform laundry weight detection. Of course, the presence or absence of clothing can be detected using the weight detection method. At this time, when there is no detected laundry amount, the laundry amount may not be displayed on the display unit 800.

Meanwhile, when the power unit 710 detects the opening and closing of the door 14, the control unit (C) determines that clothing has been put in and can perform weight detection. Of course, if there is no detected amount of laundry, the amount of laundry may not be displayed on the display unit 800, or information that there is no clothing inside may be displayed.

If there is a detected amount of laundry, the laundry treatment device of the present invention can display at least one of the weight information of the clothing, the execution time of the course and option corresponding to the amount of laundry, and the required amount of detergent on the display unit 800.

As a result, the clothing treatment device of the present invention can detect the weight of the clothing before inputting it to the execution unit 740 and transmit information such as the execution time of the course or option and the required amount of detergent to the user.

Figure 15 shows a control method for omitting laundry weight detection in the laundry treatment apparatus of the present invention.

As described above, the laundry treatment device of the present invention can detect the amount of clothing before performing the course with the execution unit 740.

The laundry treatment device of the present invention stores the detected laundry amount in the storage unit (S), and when a course is selected by the course selection unit 720, the expected execution time of the course is accurately calculated based on the stored laundry amount. You can.

The laundry treatment apparatus of the present invention may be equipped to store and continuously utilize the amount of laundry stored in the storage unit (S) until the door is opened or closed or until the amount of laundry is re-detected.

Accordingly, in the laundry treatment device of the present invention, if the amount of laundry is detected once and stored in the storage unit (S), the amount of laundry is updated in the storage unit (S) until the door 14 is opened or closed again or when the amount of laundry is re-detected. You can skip detecting the amount of laundry until it is done.

As a result, the laundry treatment device of the present invention can omit the process of detecting the amount of laundry, preventing washing delays, and improving energy efficiency by omitting rotating the drum or applying a load to the control unit (C) when detecting the amount of laundry. can increase.

Referring to Figure 15, the laundry treatment device of the present invention detects the laundry weight by rotating the drum 3 even before the power unit 710 is input or the door 14 is opened or closed, even before the execution unit 740 is input. The detection step (C1) can be performed.

The laundry weight detection step (C1) can be performed even before selecting a course with the course selection unit 720.

When the laundry weight detection is completed in the laundry weight detection step (C1), the laundry treatment device of the present invention can perform a laundry weight storage step (C2) in which the laundry weight data is stored in the storage unit (S).

The commercial laundry storage step (C2) is a step in which the controller (C) stores one or more of the laundry weight itself stored in the drum (3), the material of the clothing, and the amount of detergent required to process the laundry weight in the storage unit (S). It can be.

The storage unit (S) may be connected to the control unit (C) to receive power, but the storage unit (S) may be provided to receive power separately from the control unit (C).

The storage unit (S) may be provided to receive standby power from the laundry treatment device and maintain data on the laundry weight.

Alternatively, the storage unit (S) may be provided to continuously receive power supply from the control panel (P1, P2, and P3) coupled to the cabinet. The storage unit (S) may be installed in the control panel.

Alternatively, the storage unit (S) may be connected to a communication module of the laundry treatment device to continuously receive power.

The control panel (P1, P2, P3) or the communication module may be equipped to continuously supply standby power even if the power supplied to the control unit (C) is cut off.

Accordingly, the control panels (P1, P2, and P3) can sense the input from the power supply unit 710 even if power is not supplied to the driver unit 32 or the control unit C.

In addition, the communication module is equipped to continuously communicate with a server, etc. even when the power supply to the driving unit 32, the control unit C, etc. is cut off, so that standby power can always be supplied.

Alternatively, the storage unit S may be provided as an inactive memory in which the stored laundry weight data can be continuously stored until the stored laundry weight data is updated with other data even when the power supply is cut off.

As a result, even if the power supply to the clothing processing device or the control unit (C) is interrupted, the storage unit (S) stores the laundry weight data detected in the laundry weight detection step (C1) and records its status. It can be maintained.

Additionally, the storage unit (S) may be provided in the sensing unit (M). The storage unit (S) may be provided to store a history of whether the door 14 has opened or closed the cabinet 10 .

The detection unit (M) may be provided so that it can sufficiently detect whether the door 14 is opened or closed even with the standby power flowing through the laundry treatment device.

As a result, the storage unit (S) is connected to the sensing unit (M) or can receive and store the opening and closing history of the door through the control unit (C) when power is supplied.

Alternatively, the sensing unit (M) may be equipped to store the opening/closing history of the door 14 and transmit it to the control unit (C) or the storage unit (S) immediately or later. For example, the detection unit (M) may include a physical switch capable of detecting whether the door is open or closed, and when power is supplied to the laundry treatment device, the control unit (C) operates the detection unit (M). It may be equipped to recognize the opening and closing history of the door by detecting the switch status of the door.

As a result, the storage unit (S) can store the opening and closing history of the door even if the power supply to the clothes processing device or the control unit (C) is cut off, or the control unit (C) can store the door ( 14) You can check the opening and closing history.

When the course is completed, the laundry treatment device of the present invention may perform a power-off step (C3) to cut off power supply to the laundry treatment device. The power OFF step (C3) can be performed even when the power supply unit 710 is input.

By blocking the main power supply through the power OFF step (C3), energy consumption can be minimized.

Meanwhile, in the power OFF step (C3), standby power can be allowed to flow. The standby power may be power for booting the control panels (P1, P2, and P3) and may be power for detecting input from the power unit 710.

Additionally, the standby power flowing in the power OFF step (C3) may be supplied to one or more of the communication module, control panel (P1, P2, P3), the storage unit (S), and the detection unit (M). As a result, the laundry treatment device of the present invention can download programs from a server or an external terminal or be remotely controlled even when the power is turned off, and can maintain the storage state of laundry weight and door opening/closing history.

Meanwhile, a power ON step (C4) may be performed in which the power unit 710 receives a power command to supply power again.

When the power ON step (C4) is performed, the control unit (C) may perform a detection step (C5) to detect whether there is a history of opening and closing the door.

If the door opening/closing history has not been received from the storage unit (S) or the detection unit (M), the control unit (C) retrieves the amount of laundry stored in the storage unit (S) and displays information about the amount of laundry on the display. The information display step (C7) shown at 800 can be performed.

The information display step (C7) can be performed directly without rotating the drum (3). In other words, when power is supplied to the control unit C, the laundry weight detection step itself is skipped, and information about the laundry weight can be displayed on the display unit 800 without the drum 3 itself rotating.

The information about the laundry weight includes information on the laundry weight itself detected in the laundry weight detection step (C1), the amount of detergent required to treat the clothing corresponding to the laundry weight, and the expected time for the standard course to be performed with the clothing corresponding to the laundry weight. It may contain more than one.

The control unit (C) may perform a course input step (C8) in which a selection command for selecting a course is input to the course selection unit (720).

If a course is not selected in the course input step (c8), the control unit (C) may consider that a standard course has been automatically selected.

When the course input step (C8) is performed, the control unit (C) may perform an execution input step (C9) in which the execution unit 740 receives an execution command to perform the selected course.

When the execution unit 740 is input, the control unit C may perform a course execution step C10 of executing the course by transmitting an execution command for performing the selected course to each component of the laundry treatment device.

As a result, once the laundry weight detection step (C1) is performed, the subsequent laundry weight sensing step is omitted regardless of whether the power is turned on or off, and the course performance step (C10) can be performed directly without rotating the drum 3.

However, if there is a history of opening and closing the door in the detection step (C5), the control unit (C) can perform a re-detection step (C6) to re-detect the amount of laundry. The re-detection step (C6) rotates the drum 3 to detect the weight of the laundry through the load of the driving unit 32, and the information display step (C7) can display information about the re-detected laundry weight.

At this time, the opening and closing history of the door 14 is not only the opening and closing history of the door 14 that occurred between the power OFF step (C3) and the power ON step (C4), but also the execution input step after the power ON step (C4). (C9) The opening and closing of the door 14 that occurred before may also be included.

The laundry treatment device of the present invention may be equipped to immediately perform the re-detection step (C6) when the door 14 is opened or closed.

Figure 16 shows another control method that omits laundry weight detection in the laundry treatment apparatus of the present invention.

The laundry treatment apparatus of the present invention may be equipped to select another course through the course selection unit 720 when a certain course is performed and the execution of the course is temporarily stopped by inputting the execution unit 740, etc.

The laundry treatment apparatus of the present invention can allow the user to change to another course according to the user's will even if a specific course is performed.

Meanwhile, if water is being supplied or is in a state of being supplied while the course is being performed, if the amount of laundry is re-detected while the clothing is holding water, the amount of clothing may be excessively detected. If a course is performed with an excessively detected weight, not only will the amount of water supplied increase, but the course performance time may also increase excessively and energy consumption may also be excessive.

To prevent this, the laundry treatment apparatus of the present invention can immediately perform the changed course without re-sensing the laundry weight even if the course is changed if there is no history of opening and closing the door 14 and laundry weight detection has been performed. As a result, the laundry treatment device of the present invention can prevent water and energy waste while also preventing washing delays.

Specifically, the clothing processing apparatus of the present invention can perform the course performance step (D1) of processing clothing using the selected course.

In the course execution step (D1), the locking unit (L) can lock the door 14.

Additionally, in the course performance step D1, one or more of the course selection unit 720, the option selection unit 730, and the display unit 800 may be deactivated so that input is not possible.

In the course execution step (D1), a pause step (D2) of receiving a command to stop the course from the execution unit 740 or the like may be performed.

When the temporary stop step (D2) is performed, the lock (LOCK) of the door 14 can be released. Of course, if water is contained in the tub 2, the door 14 will be locked.

In the pause step (D2), the course selection unit 720 and the option selection unit 730 may be activated to allow input.

Accordingly, the control unit (C) may perform a change detection step (D3) in which the course selection unit 720 and the option selection unit 730 receive input to detect whether the course or option has changed.

If the execution input step (D8) in which the execution unit 740 is input again without changing the course/option is performed in the change detection step (D3), the course re-performance step (D9) in which the course is performed again may be performed. .

However, if a change in course/option is detected in the change detection step (D3), an opening/closing detection step (D4) may be performed to detect whether there is a history of opening and closing the door.

In the opening/closing detection step (D4), the control unit (C) may check whether the door is opened or closed in the detection unit (M).

When the detection unit (M) detects the opening and closing of the door, the control unit (C) rotates the drum (3) and re-detects the laundry weight through the current value applied or output to the driving unit (32). (D5) can be performed.

If the amount of laundry is detected in the re-detection step (D5), the control unit (C) may perform an information display step (D7) in which information about the re-detected amount of laundry is displayed on the display unit 800.

Afterwards, when the execution input step (D8) is performed, the course execution step (D9) in which the changed course and options are performed with the changed weight can be performed.

Meanwhile, in the opening/closing detection step (D4), there may be cases where the door is opened and closed even though there is no change in course or option. Even in this case, the re-detection step (D5) and the information display step (D7) can be performed.

Additionally, in the opening/closing detection step (D4), the door may not be opened or closed even though there is a course or option change. In this case, the information display step (D7) is performed to immediately display information on the changed course or option.

The information display step (D7) may display course or option information based on the initially detected weight. For example, in the information display step D7, the name and changes of the changed course or option, and the expected execution time of the course or option corresponding to the existing weight may be displayed on the display unit 800.

If the door is not opened or closed in the opening/closing detection step (D4), the re-detection step (D5) can be skipped and the information display step (D7) can be performed immediately, even if the course or option has changed.

The laundry treatment device of the present invention utilizes the fact that there is no change in the laundry weight if the door is not opened or closed even if the course or option is changed, and can utilize the laundry weight data stored in the storage unit (S) based on the first course.

After the information display step (D7), the execution input step (D8) and the course execution step (D9) are performed so that the clothing treatment device can be newly operated with the changed course or option.
