Description

clothes handling device

The present invention relates to a laundry treatment device. More specifically, the present invention relates to a clothes handling device capable of detecting the amount of clothes and displaying the detected amount to a user.

In general, a laundry treatment device refers to a device capable of washing, drying, or washing or drying clothes. Here, the laundry treatment device may perform only washing or drying functions, or may perform both washing and drying functions.

Such a laundry treatment apparatus has an arbitrary course or option for washing or drying clothes, and the execution time of the course or option is calculated based on the weight of the clothes. For example, if the fabric amount of clothes is large, the execution time is set relatively long, and if the fabric amount of clothes is small, the execution time is set relatively small.

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

1(a) shows a control method for a conventional laundry treatment apparatus to perform an arbitrary course or option.

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

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

Thereafter, the conventional laundry treatment apparatus performs a laundry weight detecting step (S5) of detecting the laundry quantity of laundry through a current value applied while rotating a drum accommodating the laundry. When the laundry quantity of the clothes is calculated, the control unit of the conventional clothes handling apparatus 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. (S7) is performed.

However, the laundry amount detection step (S5) and the time display step (S6) of the conventional laundry handling apparatus are performed after the start step (S3) in which the user executes a course or option. Accordingly, there is a problem in which the user is compelled to input the execution of a course or option in a state in which information on the amount of clothes or an expected execution time is not received.

As a result, the user cannot actively control the execution time of the course or option, and the time display step s6 cannot play a role beyond simply displaying simple information in terms of service to the user.

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

In addition, in the conventional clothes handling apparatus, even if the execution time of the selected course or option is not intended, to change it, the course or option can be canceled or changed unless an active action is taken, such as turning off the power of the washing machine again. There was a problem that couldn't be solved.

This inconvenience is further maximized when the conventional clothes handling apparatus is remotely controlled.

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

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

Specifically, in the conventional laundry handling apparatus, the weight of the clothes L is calculated by measuring a value of current applied to or output from a driving unit rotating the drum D while rotating the drum D in the I direction.

When the drum (D) is rotated to detect the amount of laundry in the conventional laundry handling apparatus, the clothes (L) on the bottom surface of the drum rise inside the drum (D) and then fall in the direction II by gravity while falling in the inner wall of the drum (D). can only be separated from

Therefore, in the conventional laundry handling apparatus, current values applied or output must be aligned while continuously rotating the drum D in the I direction for one or more revolutions in order to accurately detect the weight of the clothes L.

As a result, the conventional laundry treatment apparatus has a problem in that the time required to detect the amount of laundry is inevitably longer than the time required to continuously rotate the drum.

In addition, since the time required for the laundry amount detection step (S5) is set relatively long in the conventional clothes handling apparatus, the time display step (S6) for displaying the execution time of courses or options cannot be quickly provided to the user.

Furthermore, in the conventional laundry handling apparatus, the laundry weight detection is performed only when the user selects a course or option and presses an execution button (s3).

As a result, there is a limit in that the user cannot select a course or option by checking the amount of fabric in advance, and in most cases, the user has already left the clothes handling device at the time of detecting the amount of fabric.

A user's confirmation or decision command may be required in the process of the control panel (P) controlling the laundry treatment device, and the control panel (P) transmits the decision command to the group display unit (P) through the circuit board (P82). The content or request of can be displayed on the display unit P84.

In addition, the circuit board (P82) is provided so that the selection unit (R) responds to an input only when it is necessary to receive the user's intention, and when there is no need to receive the user's intention, the selection unit (R) ) may be provided so as not to react even if input. Accordingly, the control panel P can control the input of the selector R to be activated only when a user's confirmation or decision command is required.

The display unit P8 may include an induction unit 839 that displays whether or not the input of the selection unit R is activated, thereby indicating that a user needs to confirm or request a decision command.

The induction part 839 may include a lower lamp or light emitting body 821a coupled to the circuit board P82 and disposed below the display part P84. In addition, the induction part 839 may include an induction hole 835a exposing the lower lamp 821a through the mounting part P83.

The induction hole 835a may be provided as a transmission hole because the light emitted from the lower lamp 821a passes through the mounting portion P83. The lower lamp 821a may be provided as a light emitting body that emits light, and may be provided to emit light to guide a touch of the selector R while being spaced apart from the display P82.

For example, the circuit board P82 arranges a lower lamp 821a under the display unit P84 so that the lower lamp 821a turns on when the input of the selector R is activated. It can be provided as much as possible.

The lower lamp 821a may be provided as a panel such as an LED to display a decision command to be input to the selection unit R, and the display unit R may be displayed in the lower area of the display unit P84. The lower lamp 821a may be turned on while indicating which decision command the input corresponds to.

The lower lamp 821a may be disposed at the center of the left and right sides of the mounting part P83. Therefore, since the induction unit 839 can be turned on at the lower center of the display unit P84, aesthetics can be maximized rather than being biased to one side.

When the induction unit 839 is turned on, the user can input the selection unit R by recognizing that a decision command is necessary.

The selector R is integrally provided with the induction unit 839, so that the input of the induction unit 839 may be regarded as the input of the selector R.

However, since the induction part 839 is provided with a lamp 821 to emit light, and the selection part R includes the sensor R3, it may be difficult to design it as a single component. In particular, when the lamp 821 and the sensor R3 are disposed together, there is a concern that the sensor R3 may block light emitted from the lamp 821, and the lamp 821 may cause noise or noise to the sensor R3. There may be a risk of transmitting the wrong signal. Therefore, the selector R may be disposed to be spaced apart from the induction unit 839 .

As a result, the sensor hole 837 may be spaced apart from the induction hole 835a. The induction hole 835a is disposed between the seating groove 832 and the inner circumferential surface of the mounting body 831 . The sensor hole 837 may be disposed between the seating groove 832 and the inner circumferential surface of the mounting body 831 . The sensor hole 837 may be disposed in an area other than between the induction hole 835a and the inner circumferential surface of the mounting body 831 .

The selector (R) includes a sensor (R3) coupled to the circuit board (P82) to receive a decision command, a transfer unit (R2) for transmitting a decision command to the sensor (R3), and the transfer unit (R2). ) to the window P85 and may include a receiver R1 that can contact the user's body.

The receiver R1 may be attached to the rear surface of the window P85. Accordingly, the transmission part R2 may be provided to pass through the mounting body 831, and the mounting body 831 includes a sensor hole 837 providing a space through which the transmission part R2 passes. can do.

The receiving unit R1 and the transmission unit R2 are provided as conductors so that when the user's body approaches, they may be charged by current flowing through the user's body or supplied with current from the user's body. Thus, the user can input a decision command by contacting the receiver R1.

The current transmitted to the receiving unit R1 may be transferred to the sensor R3 through the transmitting unit R2, and the circuit board P2 may detect a user's touch and receive a decision command.

In general, a user may input a decision command by touching an area where the transfer unit R2 is installed.

Since the window P85 covers the induction part 839 and the selection part R, the user may not know the position of the selection part R. In addition, since the induction unit 839 induces the input of the selection unit R by emitting light, the user can recognize only the location of the induction unit 839 with the light emitted from the induction unit 839. there is.

Accordingly, the user may regard the induction unit 839 as the selection unit R and touch the area of the window P85 where the induction unit 839 is installed. At this time, if the selection part (R) is not input, the user may doubt the performance of the control panel (P).

Accordingly, even if the transmission unit R2 of the selection unit R is disposed at a predetermined distance from the induction unit 839, the reception unit R1 is at least a part of the induction unit 839 in the transmission unit R2. A user's body pressing the induction unit 839 may be sensed by extending to an area surrounding the .

The receiver R1 may be provided to cover both side surfaces and a lower portion of the induction unit 839, and cover the entirety from the lower portion of the display unit P84 and the circumference of the induction unit 839 to the inner circumferential surface of the mounting unit P83. It may be provided to do so.

Accordingly, the user's body touching the lower part of the display unit P84 may be sensed, and current generated in the user's body may be transferred to the transmission unit R2.

As a result, even if the user inputs the induction unit 839, the effect of inputting the transmission unit R2 can be achieved due to the shape of the reception unit R1.

9 shows the degree of utilization of the control panel.

In the status part or status display area D1 of the display unit P8, whether the door is locked, whether the communication module is activated, whether a course or option is operated, whether a guide message is generated, etc. may be displayed in the form of icons.

In addition, the number of display contents that can be displayed while rotating the manipulation unit P7 may be displayed in the status display area D1. For example, a plurality of dots may be spaced apart from each other, and one of the plurality of dots may provide the number of contents displayed in the contents display area D2 while emitting light.

The state unit D1 is composed of the plurality of lamps 821 described above. Since the plurality of lamps 821 inevitably transmit signals through turning on and off, state information that can be displayed through the plurality of lamps 821 may be more limited than that of the display unit P84. Accordingly, the state unit D1 may be provided to display only specific state information among a plurality of state information.

Each of the plurality of lamps 821 constituting the state unit D1 may be set to display preset state information.

The plurality of lamps 821 may be coupled to and controlled by the circuit board P82.

Icons corresponding to state information may be arranged in the window P85 according to the number of lamps 821 . For example, when the number of lamps 821 is provided with 4, a lock icon, Wi-Fi icon, run/stop icon or remote control icon, speaker notification icon or button lock icon may be printed on the window P85. can Accordingly, when corresponding state information is generated, the circuit board P82 may turn on the corresponding lamps 8211 to 8214.

For example, the plurality of lamps 821 may include a door lamp D11 displaying information about a locked state of the door. When the door lamp D11 is turned on, it may correspond to externally displaying status information indicating that the door is locked to the cabinet. To this end, an icon (for example, a key icon) related thereto may be displayed in the area of the window P85 corresponding to the door lamp D11.

The plurality of lamps 821 may include a communication lamp D12 displaying information on a state in which the communication module T1 is activated. That the communication module T1 is activated may mean a state in which the communication module T1 is connected to the AP 30 .

When the communication lamp D12 is turned on, the communication module T1 may correspond to externally displaying status information connected to the AP 30 or the external terminal 40 . To this end, a related icon (eg, Wi-Fi icon) may be displayed in the area of the window P85 corresponding to the communication lamp D12.

The plurality of lamps 821 may include a remote lamp D13 that displays status information remotely controlled by the external terminal 40 . When the remote lamp D13 is turned on, it may correspond to the external terminal 50 displaying information on the operating state of the laundry treatment apparatus to the outside. To this end, a related icon (eg, start/stop icon) may be displayed in the area of the window P85 corresponding to the remote lamp D13.

The plurality of lamps 821 may include a lock lamp D14 for displaying state information in which an input of the input unit P9 including the manipulation unit P7 is inactivated.

When the lock lamp D14 is turned on, it may correspond to externally displaying status information indicating that the input of the input unit P9 including the control unit P7 is inactivated. To this end, an icon (for example, a prohibition icon) related thereto may be displayed in the region of the window P85 corresponding to the lock lamp D14.

Meanwhile, the state unit D1 may be disposed above the display unit P84.

This is because the state portion D1 does not need to be input by a user, so there is no possibility that the display portion P84 is blocked due to the state portion D1.

In addition, since it is provided to display preset status information to the outside, the status unit D1 can be selectively turned on at the top of the display unit P84 to intuitively deliver status information to the user.

On the other hand, it is preferable that the selector (R) is disposed below the display unit (P84). This is to prevent at least a part of the display unit p84 from being blocked by the user's body when the selector R is input, since the selector R is provided to come into contact with the user's body.

In the contents display area D2, the contents of courses and options, the execution status of the courses or options, and information necessary for the user may be displayed.

The content display area D2 may be larger than the status display area D1.

In the input area D3, light may be emitted to request a user's input, and a guide message indicating what content the user should input may be displayed.

A power supply unit P46 may be provided on the left side of the display unit P8, and a performance unit P 47 may be provided on the right side of the display unit P8.

The manipulation unit P7 is rotatably provided on the outer circumferential surface of the display unit P8, and may be provided to rotate the drum 3.

The arbitrary course may be a series of control methods for performing a drying cycle for washing clothes.

When the control unit P7 is rotated, the name of the corresponding course and a brief option name may be displayed in the contents display area D2 of the display unit P8 according to the set order, and a description of the course or option may be displayed. .

The option may be selected by the setting unit P2. The setting unit P2 may be provided to receive a selection command for selecting one or more of the optional options.

The optional option may include setting additional conditions of the course.

For example, at least one of the number of repetitions of each stroke performing the course, the intensity when performing each stroke, the rotational speed of the drum when performing each stroke, the temperature of water, the amount of water, and the duration of each stroke. It may be a set algorithm or control method that adjusts the anomaly.

The setting unit P2 may include a touch display capable of selecting the optional option, and may include a plurality of lamps and a plurality of conductor switches capable of sensing a user's body.

For example, the setting unit (P2) includes an option selection unit (B) that receives a setting command for setting conditions for the course, and an option display unit (B4) displaying option information corresponding to the option selection unit (B). ) may be included.

For example, the option selection unit (B) includes a rinsing unit (B1) for adjusting the rotational speed and duration of the drum, the amount of water, and the rinsing force related to the number of times of rinsing when the course performs the rinsing cycle, and the course It may include a dehydration power dehydration unit (B2) related to the rotational speed and duration of the drum when performing the dehydration cycle, and a temperature unit (B3) to control the temperature of water when the course performs the washing cycle.

The option display unit B4 may be provided to display the rinsing power, spin-drying power, and temperature in an objective and unitized manner.

Meanwhile, the setting unit P2 may include a utilization unit C that receives a utilization command for utilizing the function of the laundry treatment device.

For example, the utilization unit (C) includes a washing unit (C1) capable of inputting a special washing process such as functional clothing, soft clothing, and tub washing, and a reservation command for inputting a reservation command to perform a washing course at a specific time. A unit (C2), a sterilization unit (C) capable of sterilizing by adding steam to the stream during the course stroke, and an additional function unit (C4) utilizing additional additional functions such as pairing with other devices can include

In addition, the setting unit P2 may include a switching unit E that receives a connection command to communicate with the drying device or mini device 60 .

The setting unit P2 may display all of the above contents through the auxiliary display P19.

Hereinafter, an embodiment and a control method for displaying and controlling the drying device or the mini device 60 with the control panel P of the washing device 10 will be described. However, this is only for removing repetitive explanations, and can be equally applied when the washing machine 10 or the mini machine 60 is controlled by the drying control panel PA.

In addition, the same can be applied when the washing machine 10 or the drying machine is controlled by the mini control panel (PC).

Fig. 10 shows an aspect in which the clothes handling apparatus of the present invention detects the amount of laundry based on the above configuration.

Referring to FIG. 10(a), the clothes may be placed on the bottom surface of the drum 3 due to their own weight.

Referring to FIG. 10(b), when detecting the amount of laundry, the laundry treatment apparatus according to the present invention may rotate the drum 3 less than one revolution.

That is, in the laundry handling apparatus of the present invention, the drum 3 can be rotated up to an angle at which the laundry is separated from the inner wall of the drum or the arrangement thereof is changed. Accordingly, it is possible to prevent unnecessary load or shock 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 apparatus of the present invention can accurately transmit the value of current applied to or output from the drive unit 32 to the control unit P, and can accurately calculate the amount of laundry of the laundry.

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

Meanwhile, as the rotating angle of the drum 3 decreases, the time for the control unit P to detect the amount of fabric of the clothes may be shortened, and an error in detecting the weight of the clothes may be reduced.

Accordingly, the laundry treatment apparatus of the present invention may rotate the drum 3 within a range of 10 degrees to 45 degrees or less when detecting the amount of laundry.

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

Accordingly, when the power supply unit P46 or the door 111 is opened or closed prior to the input of the execution unit P47, the clothes handling apparatus of the present invention immediately detects the amount of laundry and displays information related to the amount of laundry on the display unit P8 or the auxiliary display P19. can be displayed.

Fig. 11 shows an operation method for detecting the amount of laundry in the laundry treatment apparatus according to the present invention.

11(a) and 11(b), the control unit P may rotate the drum 3 less than one rotation, and in the process, the current applied to or output from the driving unit 32 value can be measured.

The control unit P may calculate (process) the amount of fabric of the clothes based on the current value.

Specifically, the control unit P, in order to detect the amount of laundry, Te = Jdw / dt + Bw + mgrsin

formula can be used.

Te is a torque value applied to the drive unit 32 and corresponds to I (current value) X K (drive unit constant).

That is, since the driving unit constant k is a unique value of the driving unit 32 itself, the control unit P may calculate a torque value applied to the driving unit 32 when sensing the current value I.

At this time, the mgrsin

from sin

In the case of , since the value decreases exponentially as the rotation angle of the drum decreases, if the rotation angle is between 15 degrees and 90 degrees or between 10 degrees and 45 degrees, sin

can be sufficiently ignored.

In addition, Bw is a frictional torque, and since B becomes very small when the drum 3 rotates, it can be ignored.

As a result, only the equation Te = Jdw/dt can remain.

At this time, since dw/dt is the angular acceleration for rotating the drum, the control unit p 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, if the current value is measured, both the torque value Te applied to the drive unit 32 and the angular acceleration dw/dt can be calculated, so the moment of inertia J can be calculated.

As a result, the laundry handling apparatus of the present invention can detect the moment of inertia (J) and immediately detect the amount of laundry of the clothing through this.

Fig. 12 shows a table in which the amount of laundry is sensed by the calculated moment of inertia in the laundry handling apparatus of the present invention.

Data describing the relationship between the moment of inertia and the amount of fabric may be stored in the control unit P.

That is, the control unit P may detect the weight of the clothing by determining the moment of inertia using the data.

For example, if the control unit P senses the moment of inertia as 55000, and the drum 3 is rotated counterclockwise according to the data, the amount of clothes can be determined as 2 kg, and the drum 3 can be rotated counterclockwise. If (3) is rotated clockwise, it can be confirmed as 3kg.

As such, the control unit p may immediately detect the amount of fabric of the clothes through data.

As a result, the control unit P can immediately detect the amount of laundry of the clothes by detecting only the current value applied or output when the drum rotates.

This laundry amount detection process may be entirely performed after the drum rotates and before restoring it to its original position. As a result, the fabric amount sensing step itself can be performed within 0.3 seconds to 1 second.

Therefore, the control unit P can sense the amount of fabric in an instant so that the user hardly feels the time to calculate the amount of fabric and guide information related to the amount of fabric.

For example, the control unit P may guide one or more of the weight of clothes, the execution time of the selected course or option corresponding to the detected laundry weight, and the required amount of detergent.

FIG. 13 shows a basic structure in which the control unit P can measure the current value of the drive unit 32 in the laundry treatment apparatus of the present invention.

Referring to FIG. 13( a ) , the control unit P may apply current to the driving unit 32 to control the driving unit 32 and may even sense current discharged from the driving unit 32 .

The control unit P controls the driving unit 32 according to a preset course or option, and the driving unit 32 rotates the drum 3 according to the command of the control unit P.

The control unit P operates by receiving an operation signal or control command from the operation unit P7, execution unit P47, or setting unit P2. It is possible to select a washing course and option for performing the washing, rinsing, and spin-drying processes with the control unit P7 or the setting unit P2.

Accordingly, washing, rinsing, and spin-drying processes may be performed. In addition, the control unit P may control to display a washing course, washing time, spin-drying time, rinsing time, or the like, or a current operating state, through the display unit P8.

The control unit P controls the drive unit 32 to rotate the drum 3 and may also vary the rotational speed of the drum 3. Specifically, the control unit P may detect the output current flowing through the driving unit 32 based on at least one of a current detection unit 225 detecting the position of the driving unit 320 and a position detection unit 220 detecting the position of the driving unit 320. The driving unit 32 can be controlled. For example, any one of the current detected by the driving unit 32 or the detected position signal may be fed back to the control unit P, and the control unit P may appropriately operate the driving unit 32 according to the feedback signal. It is possible to generate a current signal that can be controlled appropriately.

Meanwhile, in the laundry treatment apparatus of the present invention, the position detection unit 235 may be omitted and the position of the driving unit 32 may be sensed by implementing a separate algorithm. (Aka sensorless driving unit) The sensorless driving unit 32 is configured so that the control unit P can measure the current or voltage output from the driving unit 32 and determine the position of the rotor or stator in the driving unit 32. may be provided.

Hereinafter, an embodiment in which the control unit P controls the driving unit 32 will be described.

The drive unit P may be provided with a 3-phase motor so that the rotational speed can be controlled, for example, it may be provided with a BLDC motor.

Referring to FIG. 13(b), the control unit P may include an inverter 420 and an inverter control unit 430 to control the aforementioned rotor and stator. In addition, the control unit P may further include a converter 410 for supplying DC power input to the inverter 420 and the like.

That is, the control unit P may also perform the role of the inverter control unit 430 at the same time. Of course, the inverter control unit 430 may be provided separately from the control unit P. 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 to supply AC power of a predetermined frequency to the rotor 913. ) and the stator 911.

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

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

The input current detection unit (A) may detect the input current (is) input from the commercial AC power supply 405 . To this end, as the input current detector A, a current transformer (CT), a shunt resistor, or the like may be used. The detected input current (is) may be input to the inverter control unit 430 as a discrete signal in a pulse form.

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

On the other hand, the converter 410 is composed of a diode or the like without a switching element, and may perform a rectification operation without a separate switching operation. For example, in the case of single-phase AC power, four diodes may be used in a bridge form, and in the case of three-phase AC power, six diodes may 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. In the case of a three-phase AC power supply, six switching elements and six diodes may be used. When the converter 410 includes a switching element, a step-up operation, power factor improvement, and DC power conversion may be performed by a switching operation of the corresponding switching element.

The converter 410 may be connected to an output terminal, but DC power may be directly input. For example, DC power from a solar cell may be directly input to the smoothing capacitor C or may be input after being converted to DC/DC. Since DC power is stored at both ends of the smoothing capacitor C, it may be referred to as a dc terminal or a dc link terminal.

The dc short voltage detector (B) may detect the dc short voltage (Vdc) of both ends of the smoothing capacitor (C). To this end, the dc short voltage detector B may include a resistance element, an amplifier, and the like. 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 DC power (Vdc) smoothed by the on/off operation of the switching elements into three-phase AC power (va, vb, vc) of a predetermined frequency to drive a driving unit. (32) can be output. The inverter 420 has a pair of upper and lower arm switching elements Sa, Sb, and Sc and lower arm switching elements S'a, S'b, and S'c connected in series to each other, and a total of three pairs of upper and lower arms. The switching elements may be connected in parallel (Sa & S'a, Sb & S'b, Sc & S'c) to each other.

Diodes are connected in anti-parallel to each of the switching elements Sa, S'a, Sb, S'b, Sc, and S'c.

The switching elements in the inverter 420 perform an on/off operation of each switching element based on an inverter switching control signal Sic from the inverter controller 430. As a result, three-phase AC power having a predetermined frequency is output to the drive unit 32 .

The inverter controller 430 may control a switching operation of the inverter 420 . To this end, the inverter controller 430 may receive the output current io detected by the output current detector E.

The inverter controller 430 outputs the inverter switching control signal Sic to the inverter 420 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 P may sense the state of the inside of the drum by detecting the output current value io detected by the current detection unit 220 . In addition, the control unit P may detect the state inside the drum based on the position signal H detected by the position detection unit 235 . For example, while the drum 40 rotates, the amount of fabric, dehydration rate, moisture content, etc. may be sensed based on the current value io of the output current value of the drive unit 32 . In addition, the control unit P may detect the amount of eccentricity of the drum 4, that is, the unbalance of the drum 4 (UB). The amount of eccentricity may be detected based on the ripple component of the current io detected by the current detector 220 or the amount of rotational speed change of the drum 4 .

In addition, the control unit P may detect the state inside the drum by detecting the input current value is input to the inverter control unit. A process and calculation method for detecting the internal state of 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 driving unit 32 . The output current detection unit (E) detects the current flowing through the driving unit (32). The output current detection unit E can detect all of the output currents ia, ib, and 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, or the like may be used for current detection. When the shunt resistors are used, three shunt resistors are located between the inverter 420 and the driver 32, or three lower arm switching elements S'a, S'b, and S'c of the inverter 420 ) can be connected to one end, respectively.

On the other hand, using three-phase equilibrium, it is also possible that two shunt resistors are used. In addition, when one shunt resistor is used, the corresponding shunt resistor may be disposed between the aforementioned capacitor C and the inverter 420 .

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

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

Meanwhile, the position detector 235 may detect the position of the rotor of the drive unit 32 . To this end, the position sensor 235 may include a hall sensor. The detected rotor position (H) is input to the inverter controller 430 and used as a basis for speed calculation.

The speed calculating unit 520 may output the calculated position and the calculated speed based on the input position signal H of the rotor.

The current command generator 530 has an operation speed (

) and the speed command value (ω*r), the current command value (i*q) is generated. For example, the current command generation unit 530 has an operation speed (

) and the speed command value (ω*r), the PI controller 535 may perform PI control and generate the 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) together. Meanwhile, the value of the d-axis current command value (i*d) may be set to 0.

Meanwhile, the current command generation unit 530 may further include a limiter (not shown) for limiting the level of the current command value i*q so that it does not exceed an allowable range. Next, the voltage command generation unit 540 includes the d-axis and q-axis currents (id, iq) converted to the two-phase rotation coordinate system by the axis conversion unit, and the current command value (i*) in the current command generation unit 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 generation unit 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), and the q-axis current (iq). A voltage command value (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 generated. 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 generation unit 540 may further include a limiter (not shown) for limiting the level of the d-axis and q-axis voltage command values (v*d, v* q) so that they do not exceed an 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 the d-axis and q-axis voltage command values (v*d, v*q), and performs axis conversion. First, the axis conversion unit 550 converts the 2-phase rotating coordinate system into the 2-phase stationary coordinate system. At this time, the position calculated by the speed calculator 520 (

) can be used.

Then, the axis conversion unit 550 performs conversion from the 2-phase stationary coordinate system to the 3-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 an inverter switching control signal Sic according to a pulse width modulation (PWM) method based on the three-phase output voltage command values v*a, v*b, and v* c. and output

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 . Accordingly, each of the switching elements Sa, S'a, Sb, S'b, Sc, and S'c in the inverter 420 performs a switching operation.

Meanwhile, the switching control signal output unit 560 may generate and output an inverter switching control signal Sic in which a 2-phase pulse width modulation method and a 3-phase pulse width modulation method are mixed in relation to an embodiment of the present invention. there is.

For example, in an acceleration rotation section described later, an inverter switching control signal (Sic) by a 3-phase pulse width modulation method is generated and output, and an inverter by a 2-phase pulse width modulation method is used to detect counter electromotive force in a constant speed rotation section. A switching control signal Sic can be generated and output.

14 shows an embodiment in which the control unit P senses the amount of laundry through acceleration/deceleration of the drum.

The laundry treatment apparatus of the present invention may perform a sensing step (F) of detecting the amount of laundry inside the drum 3 before performing the washing cycle, the rinsing cycle, and the spin cycle cycle.

To this end, the controller (P) includes an acceleration step (F1) of accelerating the drum (3), a deceleration step (F2) of decelerating the drum (3), and acceleration of the drive unit (32) during the acceleration step. A fabric amount detection step (F3) of detecting the fabric amount of clothes accommodated in the drum may be performed through the measurement value and the measured deceleration value of the drive unit during the deceleration step.

In the laundry treatment apparatus of the present invention, while accelerating the driving unit 32, it detects an acceleration measurement value measured by the driving unit 32 or applied to the driving unit 32, and while decelerating the driving unit 32, the driving unit 32 The deceleration measurement value measured in or applied to the drive unit 32 is sensed. Thereafter, the measurement value of the acceleration and the measurement value of the deceleration are calculated to detect the amount of clothes accommodated 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 a measurement value measured by 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 driving unit 32, and the measured value may be the position sensing unit 235 or the current command value. It may be the current value or voltage value itself of the driving unit 32 measured by the sensing unit 225 .

Accordingly, the laundry handling apparatus according to the present invention omits the step of maintaining driving of the driving unit 32 at a constant speed, thereby greatly reducing the time required for detecting the amount of laundry.

In addition, the laundry treatment apparatus of the present invention can save not only the process of maintaining the drive unit 32 at a constant speed, but also energy and time required to maintain the constant speed. In addition, the laundry treatment apparatus 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 P uses the command value when detecting the amount of laundry, the control unit P feeds back the actual situation to the driving unit 32 or the actual driving status of the driving unit 32 do not need to consider Therefore, it can be simple and easy for the control unit P to calculate the amount of laundry. In addition, since the formula for calculating the amount of fabric is simplified, the value of the amount of fabric can be quickly obtained.

Specifically, the acceleration measurement value may include the acceleration current value (Iq_Acc) measured by the driving unit 32, and the deceleration measurement value may include the deceleration current value (Iq_Dec) measured by the driving unit 32. .

The acceleration current value includes a current command value (Iq*_Acc) for rotating the drive unit 32 during the acceleration step, and the deceleration current value includes a current command value for rotating the drive unit 32 during the deceleration step. It may include a value (Iq*_Dec).

On the other hand, when the control unit P uses the measured value when detecting the amount of fabric, the drive unit 32 reflects the actual situation as it is, so there is an advantage in that the amount of fabric can be accurately obtained.

And, the command value is generated only when the driver 32 is actively controlled by driving or applying power. Accordingly, when the measurement value is used, there is an advantage in that data for detecting the amount of laundry can be obtained even when power to the driving unit 32 is cut off or when the driving unit 32 is not actively controlled.

In the laundry treatment apparatus of the present invention, power is cut off in the deceleration step (F2) to decelerate the drive 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 power is cut off in the deceleration step (F2), the voltage command value may be zero. Therefore, the present invention can detect the amount of laundry by calculating only the current excluding the voltage.

That is, in the control method of the laundry treatment apparatus of the present invention, the voltage command value or the voltage value itself may be ignored or not used, and only the current value may be used, so the calculation formula for detecting the amount of laundry may be provided very simply. Since the calculation formula is simplified, the calculation can be quickly and accurately, so that the amount of laundry can be accurately detected.

Specifically, data and algorithms (hereinafter, arithmetic formulas) for calculating the measured acceleration values and the measured deceleration values may be stored in the control unit P. The above calculation formula may be provided so as not to use a voltage value from the beginning. Due to this, since there is no need to calculate the counter electromotive force, the present invention can omit the constant speed rotation step of the drive unit 32.

For example, the arithmetic expression of the present invention may be provided as follows.

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

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

The amount of change in speed can be measured by the control unit P due to the position sensor 235, calculated by measuring the time it takes to accelerate or decelerate, or can be sensed immediately by measuring a current or the like.

Therefore, the present invention can calculate the amount of laundry immediately by simply measuring the acceleration output current value (Iq_Acc) during acceleration and the acceleration output current value (Iq_Dec) during deceleration. That is, the acceleration current value includes the acceleration output current value Iq_Acc output from the drive unit during the acceleration step, and the deceleration current value includes the deceleration output current value Iq_Dec output from the drive unit during the deceleration step. can be seen doing

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

In any case, the fabric amount can be calculated with only one factor, the current value, and since the voltage factor can be omitted, the fabric amount calculation is simplified, and the speed and accuracy of the fabric value can be improved.

Therefore, even if the time of the accelerating step is very short or the time of the accelerating step is very short, the amount of fabric can be accurately sensed, so the time required for detecting the amount of fabric can be further reduced.

On the other hand, the laundry amount detection of the laundry treatment apparatus of the present invention measures the amount of laundry by decelerating immediately after accelerating. Therefore, the time itself for measuring the amount of fabric is very short, and during this time, the clothes inside the drum 3 cannot move or float. Therefore, since the amount of fabric can be detected in a short time when the state of the clothes does not change, the accuracy of calculation of the amount of fabric can be further increased.

Meanwhile, the equation applied to the laundry amount detection of the present invention uses the difference between the current value in the acceleration step and the current value in the deceleration step. Therefore, since the frictional force of the driving unit in the acceleration phase and the frictional force of the driving unit in the deceleration phase are equal to each other, the current compensation equation considering the frictional force cancels each other out. Therefore, since the frictional force of the driving unit 32 does not need to be considered in the method for detecting and controlling the amount of laundry in the laundry treatment apparatus according to the present invention, the process of correcting or tuning the frictional force can be omitted. In addition, since the fabric amount detection of the present invention does not use a voltage value, the process of compensating for or tuning an error in the voltage value can be omitted. process can be omitted. As a result, the fabric amount detection control method of the laundry treatment apparatus of the present invention derives the fabric amount immediately after substituting the current value, and since there is no procedure for compensating or tuning the fabric amount, the fabric amount can be detected very quickly and accurately.

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

Meanwhile, as can be seen from the above calculation formula, 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 deceleration step (F2), and a separate voltage value, etc. It may not be necessary to measure , and furthermore, no compensation or tuning process is required.

In more detail, the above arithmetic expression is derived by the following arithmetic expression.

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

Therefore, when the acceleration measurement value and the deceleration measurement value are measured in the same RPM section of the drum, the calculation can be further simplified because the width of the speed change is the same. 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 apparatus 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 drive unit 32.

At this time, since the above calculation formula uses the current value, the deceleration step (F2) is performed first, and then the acceleration step (Bb) is performed to measure the current value and the amount of laundry can be sensed through the same calculation expression.

Meanwhile, in the sensing step (F3), a preparation step (F0) of checking the position of the driving unit 32 is performed to set a reference value capable of performing the acceleration step (F1) and the deceleration step (F2). 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 1 rpm, and the deceleration step (F2) may decelerate the drum from the 1 rpm. That is, the acceleration step (F1) and the deceleration step (F2) may be performed continuously. The deceleration step (F2) lowers the current command value toward the driving unit 32 in the acceleration step (F1) or cuts off the voltage applied to the driving unit 32, so there is concern about burnout of the control unit P or the circuit. there is no

In this case, 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. That is, 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 the situation in which an error may occur because the amount of laundry is sensed 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, it is possible to detect the amount of laundry by measuring the current value in the same speed section band, although not in the section including the vertex. This has the advantage of improving the accuracy of the calculation by measuring the stabilized current value because the speed change is the largest at the vertex.

Meanwhile, the first rpm may be set to a lower rpm than a fixed rpm at which clothes accommodated inside the drum 4 are attached to the inner wall of the drum 4 . That is, the first rpm may be relatively lower than the rpm applied in the washing, rinsing, and spin-drying cycles.

In this case, the process of directly calculating the moment of inertia by the control unit P or the process of comparing and extracting the moment of inertia with the fabric weight data of the clothes stored in the storage unit P2 may be omitted.

The amount of current applied in the acceleration step F1 may be defined as a first amount of current, and the amount of current applied in the deceleration step F2 may be defined as a second amount of current. The control unit P may detect the amount of laundry through the first amount of current and the second amount of current.

FIG. 16 shows an embodiment in which the clothes handling apparatus of the present invention utilizes the laundry quantity detection method based on the above-described structure and method.

16(a) shows an embodiment in which the above-described fabric amount detection method is basically utilized.

When the power supply unit P46 of the laundry treatment apparatus of the present invention is input, power can be supplied to the water supply unit 23, the driving unit 32, and the drainage unit 25, and power can also be supplied to the control unit P. there is.

The control unit P may be set to sense the amount of laundry of the clothes when the power supply unit P46 is input and power is supplied.

That is, in the laundry treatment apparatus of the present invention, an essential condition for detecting the amount of laundry may be the input of the power supply unit P46.

Therefore, even when the user opens the door 132 before inputting the power supply unit P46 and puts clothes into the drum 3 and closes the door 132, the control unit P The amount of fabric on the garment can be detected immediately.

The control unit P may calculate an expected time to perform a specific course or option according to the amount of clothes.

To this end, the control unit P may recognize the expected time corresponding to the amount of clothes of the clothes by matching them.

In addition, the amount of detergent required when the control unit P performs an arbitrary course or option for the laundry amount of the clothes may also be arranged as data. The control unit P may calculate the amount of detergent required when washing the clothes according to the course or option.

For example, the laundry treatment apparatus of the present invention includes a power supply step (A1) of supplying power by inputting power to the power supply unit (P46) of the laundry treatment apparatus, and when the power supply step (A1) is performed, the drum (3) A fabric amount detection step (A2) of detecting the fabric amount of the received clothes may be performed.

In other words, the clothes handling apparatus of the present invention does not detect the amount of laundry when the execution unit P47 is input, but can detect the amount of laundry before the execution unit P47 is input.

When the amount of clothes is detected in the fabric amount detection step (A2), at least one of the amount of clothes, the expected execution time of the course or option for washing the clothes, and the amount of detergent required for the course or option is displayed on the display unit P8. An information display step (A3) in which one is displayed can be performed.

In the information display step (A3), the execution time corresponding to a predetermined standard course or standard option corresponding to the amount of clothing can be displayed.

In the information display step (A3), the user can check the amount of clothes displayed, the running time of the preset course or option, compare them with his/her own schedule, and check the amount of detergent.

In other words, the clothes handling apparatus according to the present invention may check information related to the amount of laundry before the execution unit P47 is input, select a desired course and option, and input the execution unit P47. That is, if the user is satisfied with the information displayed in the information display step (A3), the user can input the execution unit (p47). The control unit P may perform the execution input step A6 of detecting that the execution unit p47 is input.

When the execution input step A6 is performed, the control unit P controls the locking unit to lock the door 132 to the cabinet 10 to prevent the door 132 from being arbitrarily opened. there is.

When the execution input step A6 is performed, the control unit P may perform one or more of a washing operation, a rinsing operation, and a spin-drying operation according to the setting of the course or option.

However, in the information display step (A3), after the user confirms at least one of the laundry amount of clothes, the running time of the preset course or option, and the amount of detergent, the course and option are selected through the control unit P7 and selection unit P2. A selection course setting step (A4) may be further performed.

That is, the user may select an arbitrary course or option, not the standard course performed by default.

For example, after checking the amount of fabric of the clothes through the course setting step (A4), the user may input one or more of the control unit P7 and the setting unit P2, check the execution time associated with the amount of fabric, and then A course or option may be changed by inputting at least one of the control unit P7 and the setting unit P2.

When the course setting step (A4) is performed, the controller (P) recalculates the expected execution time or detergent amount of the changed course or option corresponding to the laundry amount of the clothes and transmits it to the display unit (P8). 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 amount of detergent may be displayed on the display unit P8.

The user may input the execution unit (p47) when it is determined that the expected execution time or amount of detergent is appropriate, and if the expected execution time or amount of detergent is not appropriate, one or more of the operation unit (P7) and the setting unit (P2) can be re-entered.

The control unit P may perform the execution input step A6 of sensing the input of the execution unit p47.

However, if re-input of at least one of the manipulation unit P7 and the setting unit P2 is detected, the course setting step A4 and the change display step A5 may be performed again.

As a result, the clothes handling apparatus of the present invention can complete the detection of the amount of laundry before the user selects and executes the final course and option. Moreover, by rotating the drum less than one revolution and calculating the amount of fabric within 3 seconds, information on the amount of fabric can be provided already before inputting at least one of the operation unit P7 and the setting unit P2.

For example, when the power supply unit P46 is input and the display unit P8 is booted, the laundry quantity detection is already completed, and information corresponding to the laundry quantity can be provided to the user.

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

Figure 16 (b) shows an extended embodiment of the control method of Figure 16 (a).

In the laundry treatment apparatus of the present invention, when a command is received from the power supply unit P46, at least one of the control unit P, the driving unit 32, the water supply unit 23, the drainage unit 25, and the control panel 16 operates. It is possible to perform a power input step (A1) of supplying power to.

When the power input step A1 is performed, the laundry handling apparatus may perform a laundry weight detecting step A2 of detecting the amount of laundry of the clothes.

The method of detecting the amount of fabric in the fabric amount sensing step (A2) is a method of rotating the drum less than one revolution as described above.

At this time, the control unit P may also perform a clothes sensing step (A2-1) of detecting whether or not the clothes are accommodated in the drum 3. If there are clothes in the drum 3 in the clothes detection step (A2-1), the control method of FIG. 16(a) can be performed.

However, if the clothes are not accommodated in the drum 3, the controller P may perform the door open/close detection step A2-2 to wait until the door 132 is opened and closed.

That is, if the controller P does not detect the amount of fabric of the clothes, it may wait until it detects the opening and closing of the door.

At this time, when the door open/closed detection step (A2-2) is performed, the control unit P may perform the fabric amount detection step (A2) again to additionally detect the amount of fabric of the clothes.

Accordingly, the clothes handling apparatus of the present invention can immediately sense the amount of clothes when clothes are accommodated in the drum 3 before the power supply unit P46 is input. However, when clothes are not accommodated in the drum 3 before the input of the power supply unit P46, the amount of clothes can be detected by waiting for clothes to be put into the drum 3.

In other words, in the laundry treatment apparatus of the present invention, when power is supplied to the control unit P through the input of the power supply unit P46, in principle, the laundry amount can be detected immediately.

Accordingly, when the user first puts clothes into the drum 3 before inputting the power unit P46 and inputs the power unit P46, the control unit P can detect the amount of laundry.

However, if there are no clothes inside the drum 3 before the input of the power supply unit P46, the control unit P may wait for the opening and closing of the door to detect the amount of laundry. Of course, whether or not there is clothing can be detected using a laundry amount detection method. In this case, when there is no detected amount of fabric, the amount of fabric may not be displayed on the display unit P8.

Meanwhile, when opening and closing of the door 132 is sensed after the input of the power supply unit P46, the control unit P determines that clothes are put in and detects the amount of laundry. Of course, when there is no detected amount of fabric, the amount of fabric may not be displayed on the display unit P8 or information that no clothes are inside may be displayed.

If there is a detected amount of laundry, the clothes handling apparatus of the present invention may display at least one of weight information of the clothes, execution time of courses and options corresponding to the amount of laundry, and required amount of detergent on the display unit P8.

As a result, the clothes handling apparatus according to the present invention detects the amount of clothes before inputting the execution unit p47 and delivers information such as execution time of a course or option and required amount of detergent to the user.

16 illustrates an embodiment in which the amount of laundry is detected according to whether a door is opened or closed.

Referring to FIG. 16 (a) , the controller P may be provided to detect the amount of laundry of the clothes when the opening and closing of the door 132 is sensed. That is, a condition for detecting the amount of fabric of the clothes may be the opening and closing of the door 132 .

Opening and closing of the door 132 may mean that there is a high probability that clothes are put into the drum 3 . In addition, the opening and closing of the door 132 may mean that the amount of clothing on the drum 3 is increased or decreased.

Accordingly, when the door 132 is opened or closed, the clothes handling apparatus of the present invention immediately detects the amount of laundry, and provides the user with the amount of laundry, the estimated execution time or changed execution time of the course or option, and the required amount of detergent. Or, it can guide the amount of changed tax.

The laundry treatment apparatus of the present invention may perform an opening/closing step B1 of detecting opening/closing of the door 132 . When the opening and closing of the door 132 is detected in the opening and closing step (B1), the control unit P may perform a fabric amount detection step (B2) of detecting the amount of fabric of the clothes, and the clothes according to the detected amount of fabric. An information display step (B3) of displaying one or more of the amount of laundry, the execution time of a preset course or option, and the required amount of detergent may be performed.

In other words, even before the operation unit P7 and the execution unit P47 are input, the clothes handling apparatus of the present invention detects and displays the amount of clothes within 3 seconds in the above-described manner when the opening and closing of the door 132 is sensed. can

After the information display step (B3), the controller (P) can detect whether the user inputs the execution unit (p47) and perform the execution input step (B6), and the user can select course or option. It is possible to perform the course setting step (B4) and the change display step (B5) by detecting whether or not is changed.

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

Fig. 16(b) shows an extended embodiment of Fig. 16(a).

The laundry treatment apparatus of the present invention may further perform a power input step (B0) of detecting whether or not power is input before the opening/closing step (B1).

This is because power is supplied to the controller P only when the power input step B0 is performed so that the controller P can detect whether the door 132 is opened.

Therefore, after the power input step (B0) is performed, the control unit (p) may perform the laundry amount detecting step (B2) when detecting that the door 132 is opened and closed.

When the opening and closing of the door 132 is detected in the opening and closing step (B1), the control unit P may perform a fabric amount detection step (B2) of detecting the amount of fabric of the clothes, and the clothes according to the detected amount of fabric. An information display step (B3) of displaying one or more of the amount of laundry, the execution time of a preset course or option, and the required amount of detergent may be performed.

Accordingly, when the door 132 is opened and closed while the power is supplied to the laundry treatment device, the clothes handling device of the present invention immediately senses the amount of clothes and provides the user with the clothes amount, course or option. The expected execution time or changed execution time, required amount of detergent or changed amount of detergent can be provided.

Figure 16(c) shows another extended embodiment of Figure 16(a).

In the laundry treatment apparatus of the present invention, a history of opening and closing the door 132 may be stored in the storage unit P2. That is, in the laundry treatment apparatus of the present invention, power is supplied to the control panel P through standby power even when the power supply unit P46 is not input, so that the door 132 is opened and the closed history can be stored.

Therefore, if the door 132 is opened and closed even before the power supply unit P46 is input, the clothes handling apparatus of the present invention performs the history storage step (B11) of storing the opening and closing history of the door 132 in the control unit P. can do.

Thereafter, in the laundry handling apparatus of the present invention, when the power supply unit P46 is input to supply power to the control unit P and the like (B0), the control unit P performs the laundry quantity sensing step (B2). can

Accordingly, in the laundry treatment apparatus of the present invention, even when the user opens the door 132 and puts clothes into the drum 3 before the power unit P46 is input, when the power unit P46 is input, the door ( 132), it is possible to detect the amount of laundry of the clothes by checking whether they are opened or closed.

Accordingly, the laundry treatment apparatus of the present invention can help the user select an optimal course and option or amount of detergent before inputting the execution unit p47.

As a result, the control unit P may be set to detect the amount of clothes when the power supply unit P47 is input or the sensor unit S detects that the door closes the opening.

The controller P may detect the amount of laundry only when both the power supply unit P47 and the door 132 are opened and closed, and either one of the input of the power unit P47 and the door 132 is opened or closed. When performed, it may be provided to detect the amount of laundry.

Meanwhile, in the laundry handling apparatus of the present invention, the locking part (L) can fix the door (132) to the cabinet (1) only when the execution part (P47) is input and the course and option are started. Therefore, when the laundry amount is detected before the execution unit P47 is input, the door 132 may be in an unlocked state by the locking unit L.

Accordingly, the user may open the door 132 to additionally put in clothes or take out clothes while the fabric amount detection is being performed or even after the fabric amount detection is completed.

When the opening and closing of the door 132 is additionally sensed, the clothes handling apparatus of the present invention can detect whether or not the amount of clothes has changed by re-performing the amount of fabric, and display information related to the changed amount of fabric on the display unit P8. there is.

That is, detecting the amount of fabric by detecting the opening and closing of the door may include re-detecting the amount of fabric when the opening and closing of the door is additionally detected after the first sensing of the amount of fabric.

Referring to FIG. 17 (a), when the power supply unit P46 is input, power is supplied to the display unit P8 and at the same time, a message indicating that the control unit P is booting may be displayed.

For example, the clothes handling apparatus may display information in response to the user's input of the power supply unit P46, such as “Hello”.

Referring to FIG. 17(b), the laundry treatment apparatus of the present invention can immediately sense the amount of laundry when the power supply unit P46 is input and power is supplied to the control unit P. That is, the control unit P may detect the amount of laundry while rotating the drum less than one revolution. The display unit P8 may indicate to the outside that the control unit P is in a state of sensing the amount of laundry. For example, information indicating the amount of laundry is detected, such as “detecting the weight of laundry”, may be displayed. Accordingly, the user can recognize that the laundry treatment device automatically detects the amount of laundry before manipulating the control panel P.

Referring to FIG. 17(c), when the controller P completes sensing the amount of fabric within 3 seconds, information related to the amount of fabric may be displayed outside. Information related to the amount of clothes may display weight information of clothes and expected running time for a selected course.

Meanwhile, when there is no course selected by the user through the manipulation unit P7 or the like, the execution time for the standard course may be automatically displayed.

For example, a weight range of clothing such as 2 to 4KG and 1 hour 24 minutes corresponding to the weight of the course may be displayed on the display unit P8.

Referring to FIG. 17(d), the user may input additional options by inputting the selector P2. The control unit P may calculate up to the execution time of the option corresponding to the amount of fabric, and change the expected execution time displayed on the display unit P8 to an execution time corresponding to the option.

For example, if the user changes the dehydration intensity to strong, sets the water temperature to 40 degrees, and sets the rinse cycle to 2 times, the expected execution time displayed on the display unit P8 is 1 hour 24 minutes to 1 hour 40 minutes. can be changed in minutes.

As a result, since the amount of laundry has already been detected before the execution unit (p47) is input, the clothes handling apparatus of the present invention inputs the preset standard course or the user through the control panel (P) like the operation unit (P7) and setting unit (P2). In one course and option, the execution time corresponding to the amount of laundry can be displayed.

In this way, the user can check the expected execution time and select the optimal course and option suitable for the current condition.

In addition, by injecting only an appropriate amount of detergent before input to the execution unit P47 based on the weight information of clothes displayed on the display unit P8, it is possible to prevent waste of detergent or insufficient introduction of detergent.

Referring to FIG. 17(e), when the user inputs the execution unit P47, the display unit P8 may display status information on how the control unit P or the laundry treatment machine performs courses and options.

That is, the control unit P is provided to detect the amount of laundry before the operation unit or the execution unit is input. The display unit P8 is controlled to display at least one of the weight corresponding to the detected amount of laundry, the amount of detergent, and the execution time of the course. Similarly, at least one of the weight corresponding to the detected amount of laundry, the amount of detergent, and the execution time of the course may be displayed before the execution unit is input.

The clothes handling apparatus of the present invention may display information about the detected amount of laundry on the display P84 or the auxiliary display P19.

If the display p84 and the auxiliary display p19 can be collectively referred to as the display unit p8, information about the detected amount of laundry can be displayed on the display unit p8.

Referring to FIG. 18(a), the display unit P8 may display the weight of the detected amount of fabric.

For example, if the detected weight is any one of 2kg, 3kg, 5kg, 8kg, and 14kg, the detected weight itself may be displayed on the display unit P8, such as any one of 2kg, 3kg, 5kg, 8kg, and 14kg. can

Accordingly, the user can accurately recognize the weight of the clothes and prepare a necessary amount of detergent or select an appropriate course.

Referring to FIG. 18(b), the display unit P8 may display a weight range for the detected amount of fabric.

The weight range may be an approximate range of the sensed weight. The approximate range may correspond to a critical range for changing one or more of a detergent amount corresponding to the weight or a course running time corresponding to the weight.

For example, in the weight range between 0 and 2 kg, the amount of detergent introduced and the time of the course may be the same, and the weight range of 2 to 4 kg is greater than the amount of detergent and the time of the course in the weight range of 0 to 2 kg, In the weight range of 2 to 4 kg, the amount of detergent introduced and the running time of the course may be the same.

In addition, the weight range of 4 to 6 kg is greater than the amount of detergent and the time of the course in the weight range of 2 to 4 kg, but in the weight range of 4 to 6 kg, the amount of detergent and the course time may be the same.

In the weight range of 6 to 9 kg, the amount of detergent added and the time of the course may be greater than in the weight range of 4 to 6 kg, but in the weight range of 6 to 9 kg, the amount of detergent and the course time may be the same.

In addition, in the weight range of 9 kg or more, the amount of detergent injected and the course running time may be greater than in the weight range of 6 to 9 kg, but in the weight range of 9 kg or more, the amount of detergent injected and the course running time may be the same.

Accordingly, when the detected fabric weight is 2kg, the range of 0 to 2kg is displayed, when the detected fabric weight is 3kg, the range of 2 to 4kg is displayed, and when the detected fabric weight is 5kg, the range of 4 to 6kg is displayed. , and when the detected fabric amount is 8 kg, a range of 6 to 9 kg is displayed, and when the detected fabric amount is 14, a range of 9 or more may be displayed.

Accordingly, by displaying the weight range of the clothes, the clothes handling apparatus may take into consideration even the occurrence of an error in the weight of the clothes and display the weight range.

In addition, the weight range may be a weight range corresponding to the amount of detergent to be injected.

When a company that produces and supplies detergent determines a range of amount of detergent to be injected according to a weight range, the weight range may be a weight unit or weight range corresponding to the amount of detergent indicated on the detergent provided by the company.

The weight range provided by the company supplying the detergent is a standard range and may be a weight unit or weight range commonly used by other companies.

In this way, the user can determine the weight unit or weight range of the clothes and input a corresponding amount of detergent.

Referring to FIG. 18(c), the display unit P8 may display the detected weight as moving. For example, the display unit P8 may display the detected weight while moving from left to right, and at least one of both sides of the displayed weight may display a symbol unrelated to a number.

Accordingly, the user can recognize that the number displayed on the display unit P8 is weight information about the detected amount of fabric.

As described above, the laundry treatment apparatus according to the present invention not only quickly detects the amount of fabric, but also can detect the amount of fabric before the operation unit P7, the setting unit P2, and the execution unit P47 are input. Hereinafter, various independent embodiments that can be implemented or executed by the laundry treatment apparatus of the present invention unlike conventional laundry treatment apparatuses due to these characteristics will be described.

The clothes handling apparatus of the present invention may recommend courses and options suitable for or corresponding to the detected amount of laundry before the user operates the control panel P.

That is, the control unit P may detect the amount of laundry in advance before the user selects a course and option, determine an appropriate course and option, and display the course and option on the display unit P8 to make a recommendation.

Accordingly, the user can confirm the recommended courses and options through the display unit P8, and perform suitable courses and options simply by inputting only the execution unit P47.

In addition, the control unit P may be provided to recommend a course corresponding to the detected fabric amount through the display unit P8 when the course selected by the control unit does not correspond to the detected fabric amount.

In addition, the laundry treatment apparatus of the present invention may determine necessary guidance items based on the detected amount of laundry.

For example, when a course and option unsuitable for the detected amount of laundry are selected, the control unit P may display on the display unit P8 a guide leading to selection of another course and option or to take necessary measures. .

The control unit P may display recommended courses and options or information on the display unit P.

In this way, the user can be guided to select a suitable course and option or to take a suitable action based on the contents displayed on the display unit P. As a result, erroneous use of the laundry treatment machine can be prevented.

The display unit P8 of the laundry treatment apparatus of the present invention may further include a speaker P88.

The laundry handling apparatus according to the present invention can transmit contents or information displayed on the display unit P8 to the user through the speaker P88 through audio or voice.

Accordingly, the user can take necessary measures by being guided by audio or voice of recommended information or necessary information displayed on the display unit P8 even without directly looking at the display unit P8.

In particular, since these processes are all performed after the power supply unit P46 is input and before the user inputs the execution unit P47, the user does not have to wait indefinitely to receive recommendations for courses and options or to receive necessary information.

Furthermore, since the user stays near the display unit P8 until inputting the execution unit P47, the user can immediately check the recommended contents or necessary information displayed on the display unit P8.

Referring to FIG. 19(a), the user may select a speed course by inputting the additional function unit C4 or the like in the setting unit P2 or manipulating the control unit P7.

The speed course is a course for quickly washing a small amount of laundry, and can be regarded as a course that finishes the washing cycle faster while having higher energy efficiency than the standard course because the amount of water used, the rotation speed of the drum, and the rotation duration are smaller.

Referring to FIG. 19 (b), when the user selects the speed course, the display P84 of the display unit P8 displays a state in which the speed course is selected, and information on the speed course may also be displayed. .

When the weight of the clothing is detected as suitable for the standard course, the control unit P selects a speed course with a shorter execution time than the standard course through the control unit P7, etc., and displays the standard course through the display unit P8. It may be provided to recommend a course.

Specifically, if the user selects the speed course even though the amount of fabric detected by the controller P is a large amount of fabric that is not suitable for the speed course, the control unit P sends information indicating that the speed course is not suitable to the display unit ( P8) can be displayed.

On the display unit P8, it is possible to display that the detected amount of fabric is not suitable for the speed course, and another course suitable for the heavy or large amount can be recommended.

For example, the display unit P8 may recommend information about the detected amount of fabric, such as “a lot of laundry,” and a course suitable for the detected amount of fabric, such as “I recommend a standard course.”

The displayed contents may be emitted through audio or voice through the speaker P88.

As a result, the user may realize that the speed course is not suitable and be guided to select a standard course or the like. As a result, a course suitable for the amount of laundry is performed, so that the performance of the laundry treatment machine can be guaranteed.

Referring to FIG. 20(a), the user may input the power supply unit P46, select a course and option by selecting the control unit P7, or automatically select a standard course. At this time, the user may want to perform a standard course or the like by directly inputting the performing unit P47.

However, the control unit P may be provided to recommend a speed course having a shorter running time than the standard course through the display unit P8 when the detected amount of fabric is small.

However, even if the user selects another course like the standard course, the currently selected course is displayed on the display unit P8 to indicate that the user's command has been input.

For example, the word “standard” may be displayed on the display unit P8 to display a course selected by the user.

At the same time, the control unit P can display information on the detected amount of laundry and a recommendation phrase suitable for this on the display unit P8.

For example, it is possible to recommend a small amount of fabric detected, such as “The amount of laundry is small”, and other courses and options suitable for the amount of fabric detected, such as “I recommend a speed course for low weight”.

Accordingly, the user can recognize a course suitable for the detected amount of laundry and perform the recommended course by inputting the execution unit P47. In addition, the user may check the existence of other courses and options, and may learn which courses and options are suitable for the detected amount of laundry.

This process may be performed before the user inputs the execution unit P47. In addition, even if the user inputs the performer P47, contents recommending other courses may be displayed through the display unit P8. As a result, the user may confirm this, stop the course, and reselect the recommended course.

All guidance information can be output as audio or voice through the speaker P88.

Referring to FIG. 21 (a), the chewing gum treatment apparatus of the present invention may provide a tub 2 and drum 3 course of washing or sterilizing the tub 2 and the drum 3 with hot water or steam.

The whole sterilization course can be selected through the operation unit P7 or by inputting the whole sterilization course C42 through the additional function unit C4.

Since the whole sterilization course is a course for removing germs or contaminants from the tub 2 and drum 3, the environment inside the drum 3 may be more fatal to clothes than a general washing course.

Furthermore, if the whole sterilization course is performed while there are clothes inside the drum 3, the clothes may be exposed to bacteria or foreign substances.

On the other hand, the user can put clothes into the drum 3 or select the whole sterilization course while putting clothes on. However, the clothes handling apparatus according to the present invention can detect the presence of clothes inside the drum 3 by already detecting the amount of clothes before the user selects the whole sterilization course.

Referring to FIG. 21(b), the user can select a whole sterilization course while there are clothes inside the drum 3.

At this time, the control unit P may inform the user through the display unit P8 that the whole sterilization course is not suitable when clothes are present inside the drum 3.

For example, the control unit P can detect the amount of laundry to recognize in advance not only the amount of laundry inside the drum 3 but also whether or not there is a laundry. can be guided to withdraw from the drum (3).

The display unit (P8) can display course contents selected by the user, such as “total sterilization,” and can also display status information that detects the presence of clothes, such as “There is laundry,” and “Take it out” and Similarly, a notice to induce withdrawal of clothing may be displayed.

As a result, the control unit P may guide the withdrawal of the clothes through the display unit P8 when the whole sterilization course is selected with the control unit P7 or the like in a state in which clothes are detected inside the drum. there is.

In addition, the control unit P, in a state where the control unit P detects clothes inside the drum and the control unit P7 or the like selects the whole sterilization course, instructs the controller P to perform another course other than the whole sterilization course. can also recommend

Referring to FIG. 22(a), the controller P may also detect whether the clothes are wet when detecting the amount of fabric.

The control unit p may detect whether or not the clothes are wet using a current value applied to or output from the driving unit 9 .

The figure on the left shows a case where the clothing such as a dry towel is a dry cloth, and the figure on the right shows a case where the clothing such as a wet towel is a wet cloth.

When the wet cloth and the dry cloth have the same weight (eg, 5 kg), the current value of the drive unit 9 for rotating the drum 30 may not be significantly different. However, in the case of the wet cloth, since the contact force is better than that of the dry cloth, a large amount of clothes may fall to the inner wall of the drum at the same time whenever the drum rotates once. As a result, a higher vibration value can be sensed when the wet cloth is compared to the dry cloth.

Accordingly, the control unit P may detect that the clothes are wet when the vibration value generated by the drum 30 is greater than the reference value or when a one-time vibration waveform is generated as the drum 30 rotates.

When the clothes are wet, the actual weight of the clothes may be smaller than the weight of the clothes detected in the fabric amount detection step by the amount of water absorbed by the clothes.

Accordingly, the control unit P may calculate the weight obtained by removing the amount of moisture from the weight of the clothes, or calculate the weight of the clothes when the wash water level is suitable for washing.

Accordingly, the control unit P may estimate or predict the weight of the clothes when the clothes are dry, and change the execution time of the course or option or the amount of detergent to be displayed.

As a result, when the drum is rotated, the control unit may recognize the clothes as a wet cloth when the maximum vibration value compared to the amount of fabric is large.

Referring to FIG. 22(b), the display unit P can detect that it is wet and deliver necessary guidance.

* In addition, the display unit P8 may also guide that if the clothes are wet, spin-drying first, or that the execution time of the selected course may be adjusted to be smaller.

For example, it can be indicated that the applied clothes are wet, such as “You put wet clothes in”, and that the appropriate execution time is adjusted because it is wet, such as “Adjust the washing time”.

As a result, the user can more trust the performance of the laundry treatment machine. In addition, the laundry treatment apparatus can prevent consumption of more water, energy, and time by misrecognizing the amount of laundry.

Such information may be output as audio or voice through the speaker P88.

The laundry treatment apparatus of the present invention may be provided to sense the amount of laundry when at least one of input of the power supply unit P46 and opening/closing of the door 132 is detected. As a result, the laundry treatment apparatus according to the present invention can detect the amount of laundry before the operation unit P7 and execution unit P47 are input.

However, the user may input the execution unit P47 while the laundry treatment apparatus detects the amount of laundry.

For example, when the power supply unit P47 is input to the laundry treatment apparatus, the standard course may be automatically selected even before the operation unit P7 is input. In this process, the performing unit P47 may be input.

Even if the clothes handling apparatus according to the present invention rapidly detects the amount of laundry when the power supply unit P47 is input, the execution unit P47 may be input when the laundry quantity detection is not completed.

If the course and option are executed when the execution unit P47 inputs the input when the laundry amount detection is not completed, the clothes handling apparatus of the present invention not only cannot recommend a course and option according to the amount of fabric, but also the amount of detergent or course according to the amount of fabric. cannot tell you the expected execution time of

Furthermore, since the locking unit L locks the door 132 when the course is performed, a problem may occur in which the user cannot additionally put in or take out clothes in the middle.

Accordingly, the laundry handling apparatus according to the present invention may perform the courses and options after the control unit P completes the detection of the laundry amount of the clothes, regardless of whether the execution unit P47 is input.

Accordingly, the control unit P may control the locking unit L to lock the door 132 after the laundry amount detection is completed. In addition, even if the execution unit P47 is input until the laundry amount detection is completed, the locking unit L does not lock the door 132, and the courses and options can be waited for immediately without being executed.

As a result, after the laundry amount detection is completed and the information on the amount of laundry, the expected execution time of the course, and the required amount of detergent are displayed on the display unit P8, the locking unit L locks the door 132 to the cabinet, and the course and options this can be done

Meanwhile, the control unit P may be provided to detect the fabric amount of the clothes again after temporarily suspending the process of detecting the fabric amount of the clothes when the execution unit P47 is input in the process of detecting the fabric amount of the clothes. there is.

This is to guide accurate laundry amount detection by blocking variables since the clothes handling apparatus of the present invention rapidly measures the amount of laundry while rotating the drum less than one rotation, but noise and even small vibrations can affect the amount of laundry. .

As a result, even if the execution unit P47 is input, the clothes handling apparatus of the present invention preferentially delivers information according to the accurate laundry amount detection to the user, thereby guaranteeing the option of changing courses and options or additionally putting in or taking out clothes. there is.

Specifically, the clothes handling apparatus of the present invention performs a power input step (V1) of detecting that a power command for supplying power to the control unit is input to the power supply unit (P47), whether the door has closed the opening 132 or not. A door detection step (V2) for detecting may be performed.

If the door 132 opens the opening 111 in the door sensing step V2, it may wait until the door 132 closes the opening 111.

When the door 132 closes the opening 111, the laundry amount detection step V3 may be performed by rotating the drum less than one revolution to detect the amount of laundry.

The laundry amount detection step (V3) detects the amount of laundry through a current value applied or output when the drum is rotated less than one revolution, and the rotation angle of the drum is an angle at which clothes are separated from the inner wall of the drum or the arrangement of clothes is changed. It can be set below.

The controller P can calculate the amount of fabric within 2 seconds after the drum is rotated in the step of detecting the amount of fabric (V3), and the display unit P8 displays information related to the amount of fabric detected within 3 seconds (V7). ) can be performed.

The information displaying step (V7) may include displaying an estimated running time corresponding to the changed course and option when the course and option are changed by the manipulation unit P7.

If the opening and closing of the door is additionally detected after the fabric amount detection step V3 is performed, the fabric amount detection step V3 is performed again, and information related to the newly detected fabric amount may be displayed in the information display step V7. .

In addition, when the power supply unit P47 is re-input and the power input step V1 is re-performed, the fabric amount detection step V3 is re-performed, and the information display step V7 also displays information corresponding to the re-detected fabric amount. can do. This is because clothes may be additionally put in or taken out while the power supply unit P47 is re-entered, or the state of the laundry treatment device may change.

On the other hand, an execution input step (V4) in which an execution unit P47 for receiving an execution command for executing any one course of arbitrary courses is input to the control unit P may be performed.

When the execution input step (V4) is performed, a locking step (V6) in which the locking part (L) fixes the door 132 to the cabinet 1 may be performed, and the detected information in the information display step (V7) may be performed. Any one of courses and options being performed according to the amount of clothes, expected execution time or remaining time may be displayed.

In addition, a washing step (V8) in which the courses and options input in the execution input step (V4) are performed may be performed.

Meanwhile, the execution input step (V4) may be performed during the laundry amount detection step (V3). Accordingly, the laundry handling apparatus according to the present invention may additionally perform a detection check step (V5) for checking whether or not the amount of laundry is detected when the execution input step (V3) is performed.

If the fabric amount detection is not completed in the detection check step V5, it may wait until the fabric amount detection step V4 is completed. In addition, if the fabric amount detection is not completed in the detection and check step V5, the fabric amount detection step V4 may be interrupted and re-performed.

Accordingly, the locking step V6 may wait without being performed until the sensing check step V5 is finished.

In the laundry treatment apparatus of the present invention, when the execution unit P47 is input, the locking unit L may be controlled to lock the door 132 to the cabinet 1 .

At this time, if the execution unit P47 is input, the locking unit L can lock the door 132 to the cabinet 1 even before the control unit P completes the detection of the amount of clothes. .

In this way, after the execution unit P47 is input, it is possible to block the changing of the state inside the drum 3 so that the optimal course and option can be performed with the detected laundry amount.

Even before the execution unit P47 is input, the clothes handling apparatus of the present invention performs laundry amount detection when the power supply unit P47 is input or the door 132 opens and closes the opening.

In the clothes handling apparatus of the present invention, even if the execution unit P47 is input while the laundry amount is being detected or before the laundry amount is detected, the locking unit (L) can lock the door (132) to the cabinet (1). can

Of course, the course commanded to be executed by the execution unit P47 may be executed after the laundry amount of the clothes is detected. Accordingly, the execution time of the course and option corresponding to the detected amount of linen can be determined, and the remaining execution time or expected execution time of the course can be immediately displayed to the user. Even if the user inputs the execution unit (P47), he or she can check the estimated execution time, remaining execution time, etc., and move to another place.

As a result, when the execution unit P47 is input, the clothes handling apparatus according to the present invention first locks the door 132 to block the input or withdrawal of additional clothes, thereby respecting the intention of the user who inputs the execution unit P47. can

Of course, if the execution unit P47 is input during the fabric amount detection, the existing fabric amount detection may be stopped and the fabric amount detection may be re-performed.

Specifically, the clothes handling apparatus according to the present invention performs a power input step (X1) of detecting that a power command for supplying power to the control unit is input to the power supply unit (P47), whether the door has closed the opening 132 or not. A door sensing step (X2) of detecting may be performed.

If the door 132 opens the opening 111 in the door sensing step (X2), it may wait until the door 132 closes the opening 111.

When the door 132 closes the opening 111, the laundry amount sensing step X3 may be performed by rotating the drum less than one revolution to detect the amount of laundry.

In the laundry amount sensing step (X3), the amount of laundry is sensed through a current value applied or output when the drum is rotated less than one revolution, and the rotation angle of the drum is an angle at which the clothes are separated from the inner wall of the drum or the arrangement of the clothes is changed. It can be set below.

In the laundry amount detection step (X3), the control unit P can calculate the amount of fabric within 2 seconds after the drum is rotated, and the information display step (X7) in which information related to the detected amount of fabric is displayed on the display unit P8 within 3 seconds. ) can be performed.

The information displaying step (X7) may include displaying an estimated execution time corresponding to the changed course and option when the course and option are changed by the manipulation unit P7.

If the opening and closing of the door is additionally detected after the fabric amount detection step X3 is performed, the fabric amount detection step X3 is performed again, and information related to the newly detected fabric amount may be displayed in the information display step X7. .

In addition, when the power supply unit (P47) is re-input and the power input step (X1) is re-performed, the fabric amount detection step (X3) is re-performed, and the information display step (X7) also displays information corresponding to the re-detected fabric amount. can do. This is because clothes may be additionally put in or taken out while the power supply unit P47 is re-entered, or the state of the laundry treatment device may change.

Meanwhile, an execution input step (X4) in which an execution unit P47 for receiving an execution command for executing any one course of arbitrary courses is input to the control unit P may be performed.

When the execution input step (X4) is performed, a locking step (X5) in which the locking unit (L) fixes the door 132 to the cabinet 1 may be performed.

At this time, any one of course and option execution with the detected laundry amount in the information display step (X7), expected execution time or remaining time may be displayed.

In addition, a washing step (V8) in which the courses and options input in the execution input step (X4) are performed may be performed.

Meanwhile, the execution input step (X4) may be performed during the laundry amount sensing step (X3).

At this time, if the execution input step (X4) is performed, the locking step (X5) may be preferentially performed even before the laundry quantity sensing step (X3) is completed.

Thereafter, a detection check step (X5) for checking whether or not the linen amount detection is completed may be performed.

If the fabric amount detection is not completed in the detection and check step X6, it may wait until the fabric amount detection step X4 is completed. In addition, if the fabric amount detection is not completed in the detection and check step (X6), the fabric amount detection step (X4) may be interrupted and re-performed.

The information display step (X7) can be performed only after the detection and check step (X6) is completed. Thus, in the information display step X7, information based on the detected amount of laundry can be accurately displayed to the user.

25 illustrates a control method when the laundry amount detection fails.

The laundry treatment apparatus of the present invention is provided to sense the amount of laundry by controlling the drive unit 32 before the execution unit P47 is input.

When detecting the amount of laundry, the control unit P uses a current value applied to or sensed by the driving unit 32 .

However, if the driving unit 32 is not controlled, the laundry treatment apparatus of the present invention may determine the amount of laundry of the laundry as a reference value.

The fact that the driving unit 32 is not controlled may include a state in which the driving unit 32 is inoperable, does not accurately rotate at a designated rotation angle, or the driving unit 32 is overloaded.

Since the driving unit 32 has a motor structure such as a stator and a rotor, when it is overloaded or overheated, the magnetic flux may be weakened or the error in the position to be controlled may increase, so that it may not be properly controlled. The drive itself of the drive unit 32 may fail.

Such an overload of the driving unit 32 may occur when a new course and option are performed again immediately after the course and option have been performed by the laundry treatment apparatus. In addition, such an overload of the drive unit 32 may occur when a new course and option are performed again after a course and option are interrupted while being performed.

In any case, if the driving unit 32 is in an overload state, the control unit P cannot accurately detect the amount of laundry.

After waiting until the overload state of the driving unit 32 is resolved, the control unit P may control the driving unit 32 again to detect the amount of laundry. However, the time during which the overload state of the driving unit 32 is resolved may be longer than the time interval between when the user inputs the power supply unit P46 and the execution unit P47, and the user operates until the user inputs the execution unit P47. There is a possibility that the information corresponding to the amount of laundry cannot be confirmed.

In order to prevent this, if the laundry amount cannot be detected due to an overload of the drive unit 32 or the like, the clothes handling apparatus of the present invention may stop detecting the amount of fabric and temporarily assign the amount to the reference value and display the amount.

The display unit P8 may display information corresponding to the reference value. That is, the display unit P8 may be controlled to display one or more of the weight corresponding to the reference value, the course execution time, and the amount of detergent.

For example, the reference value may correspond to the highest amount. Accordingly, it is possible to inform the user that the execution time of the course corresponding to the largest amount is required. Through this, the user is able to determine a future schedule, and thus disruption to the user's schedule can be prevented. In addition, by inducing the user to input the maximum amount of detergent, it is possible to prevent deterioration in washing effect due to lack of detergent.

Also, the reference value may correspond to a reference fabric weight. The reference fabric weight may correspond to a weight fabric weight, an average fabric weight mainly used by a user, or a previously used fabric weight.

Accordingly, it is possible to inform the user that an average course execution time is required. Through this, it is possible to reduce the difference between the time when the actual course ends and the expected running time, and thus, it is possible to prevent unreasonable changes to the user's schedule.

In addition, by inducing the user to inject a conventional detergent, it is possible to prevent excessive detergent from being introduced.

Meanwhile, the clothes handling apparatus according to the present invention may re-detect the amount of laundry when the overload of the motor is resolved. Accordingly, the laundry handling apparatus of the present invention can correct and display information corresponding to the redetected amount of laundry.

As a result, the user can check the information corresponding to the corrected amount of laundry to confirm a schedule or adjust the amount of detergent to be injected.

Meanwhile, even if the laundry handling apparatus of the present invention fails to detect the amount of laundry, it may repeatedly attempt to detect the amount of laundry until it is determined whether the motor is overloaded. Accordingly, when the laundry quantity detection is not performed due to a temporary error, the laundry quantity detection is quickly retried and information corresponding to the textile quantity can be delivered to the user.

For example, if the laundry amount detection fails, the laundry handling apparatus of the present invention may retry the laundry amount detection for a reference time. Since the clothes handling apparatus of the present invention can detect the amount of laundry by rotating the drum less than one revolution, it can be retried at least three times even if the reference time is short.

For example, the reference time may correspond to 3 seconds.

However, if the attempt to detect the amount of laundry repeatedly during the reference time fails, the laundry treatment apparatus of the present invention may stop detecting the amount of laundry for a specific time period. The specific time may be set to a time longer than a time during which the overload of the motor is resolved. For example, the specific time may be set to a time during which the temperature of the motor can be cooled, and may be set to 3 minutes or longer.

Alternatively, the laundry treatment apparatus of the present invention may further perform the laundry quantity detection as many times as the reference number of times when the laundry quantity detection fails. Since the laundry amount detection can be performed within 1 second, the reference number of times can be set to 3 times.

If the laundry quantity detection fails during the reference number of times, the laundry treatment apparatus of the present invention may stop detecting the quantity of laundry for a specific period of time.

Meanwhile, the course may be changed by inputting the control unit P7 during the specific time period. However, the expected execution time for the course may be fixed. This is to avoid misleading the user by changing the expected execution time since the reference value is a temporary value.

The laundry treatment apparatus of the present invention may display information corresponding to the reference value before input of the execution unit P47 even if the laundry amount detection is impossible due to an overload of the drive unit 32 . Accordingly, the user may not doubt the performance or function of the laundry treatment apparatus.

Also, during the specific time period, the execution unit P47 may be input and courses and options may be performed. When the execution unit P47 is input, the locking unit L can block the door 132 from being opened by locking the door 132 to the cabinet 1 .

In this case, it is possible to perform the course and option first with the amount of fabric corresponding to the reference value, so that delay in washing can be prevented. Normally, 3 minutes of the specific time may correspond to the time when water is supplied, so if the amount of laundry is large after that, if the laundry amount is successfully detected, additional water may be supplied.

After that, courses and options can be performed, starting with normal watering. Meanwhile, if a specific time elapses while the courses and options are being executed, the amount of fabric can be re-detected.

Conversely, in the laundry handling apparatus of the present invention, if the amount of laundry is not detected for the reference time, the course and option can be waited for to be executed even if the execution unit P47 is input. That is, the laundry treatment apparatus of the present invention may not execute courses and options until the amount of laundry is sensed even if the execution unit P47 is input. This is because there is no need to forcibly supply water to the inside of the tub 2 when the amount of laundry is not detected is not an overload of the motor but a problem in other configurations.

When the amount of fabric is re-sensed, the display unit P8 may display a state in which the amount of fabric is re-sensed. Accordingly, the user can recognize that the laundry treatment apparatus re-detects the amount of laundry, and can more trust the content displayed by the laundry treatment apparatus.

Meanwhile, the laundry treatment apparatus of the present invention may detect the amount of laundry again when the specific time elapses. The laundry handling apparatus of the present invention may display an error on the display unit P8 if the laundry quantity cannot be detected even after a specific time elapses and the laundry quantity detection is re-performed.

This is because, when the specific time elapses, the driving unit 32 is mostly relieved of the overload state, so it can be determined that the laundry amount detection is not impossible due to the driving unit 32 being overloaded.

The above error can be direct information such as “Cannot detect fabric weight”, “Motor error has occurred”, or comprehensive information such as “Contact the manager”.

As a result, the user can recognize that there is a problem in the laundry treatment apparatus by checking the error display, and can not forcefully operate the laundry treatment apparatus.

Meanwhile, in the laundry handling apparatus of the present invention, when the laundry quantity detection is successful when the laundry quantity detection is re-performed after the elapse of the specific time, the display unit P8 displays at least one of the weight, execution time, and amount of detergent corresponding to the detected laundry quantity. It can be corrected and displayed.

In this way, the user can check information corresponding to the accurately sensed amount of laundry.

In addition, the laundry treatment apparatus of the present invention may display the estimated running time of the course corresponding to the corrected amount of laundry. In this way, the user can accurately check the time when the course ends.

In addition, when the overload of the drive unit 32 is relieved, the clothes handling apparatus of the present invention can immediately detect the amount of laundry and accurately deliver information corresponding to the amount of laundry to the user. In addition, washing performance can be guaranteed and energy waste can be prevented by correcting the execution time of courses and options based on the detected amount of fabric.

Hereinafter, with reference to FIG. 24, an embodiment in which the above-described process can be implemented as a control method will be described.

The laundry treatment apparatus of the present invention may include a power supply step (Z1) of receiving a power command for supplying power to the control unit P by pressing the power unit P47.

When the power supply step (Z1) is input, the clothes handling apparatus of the present invention may perform a door sensing step (Z2) for detecting whether the door is opened or closed or whether the door closes the opening through the sensor unit (S). .

When the power supply step (Z1) and the door detection step (Z2) are completed, the laundry treatment apparatus according to the present invention may perform a laundry amount detection step (Z3) of rotating the drum 3 less than one rotation to detect the amount of laundry. .

The laundry treatment apparatus of the present invention may perform a detection check step (Z4) of checking whether or not the amount of fabric has been detected in the laundry amount detection step (Z3).

When the detection of the amount of linen is completed in the detection and checking step Z4, the information display step Z5 of displaying information corresponding to the detected amount of linen on the display unit P8 may be performed.

The information corresponding to the amount of fabric may be at least one of a weight, an expected running time of a course corresponding to the amount of fabric, and a required amount of detergent corresponding to the amount of fabric.

When the information display step (Z5) is completed, an execution input step (Z10) in which the control unit P receives an execution command for performing the course selected by the manipulation unit (P7) may be performed, and the execution input step (Z10) is performed, a locking step (Z11) in which the locking part (L) fixes the door 132 to the opening 111 may be performed.

Thereafter, a washing step (Z16) in which a washing cycle is performed with the selected course and option is performed, and the control method may be terminated.

However, if it is not detected that the fabric amount detection is completed in the detection and check step (Z4), it is possible to attempt to detect the fabric amount again. The reference time may correspond to 3 seconds.

Specifically, if the detection of the amount of linen is not completed in the sensing and checking step (Z4), first, the sudden braking step (Z6) of stopping the rotation of the drum may be performed.

After the sudden braking step (z6), a count determination step (Z7) for checking whether the amount of fabric has been detected as much as the reference number (N) may be performed. The reference number of times (N) may correspond to number 3.

If the number of detections in the count determination step (Z7) is less than the reference number, the laundry treatment apparatus of the present invention may perform the laundry amount detection step (Z3) again.

However, when the number of times of detection reaches the reference number N, the control unit P may determine that the amount of linen is no longer sensed, and may perform a fabric amount allocation step Z8 of forcibly allocating the amount of fabric.

The amount of fabric allocated in the fabric amount assignment step may correspond to the reference value.

The control unit P may perform a temporary display step Z9 of displaying information corresponding to the amount of laundry corresponding to the reference value on the display unit P8.

The temporary display step (Z9) may be performed before the execution input step (Z10). Of course, even if the execution input step (Z10) is performed before the temporary display step (Z9), the temporary display step (Z9) may be performed as it is.

When the execution input step (Z10) is performed, the door locking step (Z11) may be performed.

However, the laundry handling apparatus according to the present invention may perform the redetecting step (Z12) of detecting the amount of laundry again after a specific period of time has elapsed. The specific time is a time during which the overload of the motor is resolved, and may correspond to 3 minutes.

In the redetecting step (Z12), a rediscovery check step (Z13) for determining whether the amount of linen has been detected may be performed.

Meanwhile, the washing step (z16) can be performed only when the detection of the amount of laundry is completed in the re-detection check step (z13).

However, in the rediscovering step z12, the washing step z16 may be performed first. In this way, delay in washing can be prevented. However, if the amount of fabric is not detected in the rediscovery check step (Z13), the washing step (z16) may be stopped.

When the detection of the amount of fabric is completed in the re-detection check step (Z13), an information change step (Z17) of correcting and displaying information corresponding to the detected amount of fabric on the display unit P8 may be performed.

However, if the detection of the amount of laundry is still not completed in the re-detection check step (Z13), the control unit P may perform an error display step (Z15) of displaying an error message on the display unit P8.

In the error display step (Z15), the washing step (Z16) may be blocked.

As described above, the laundry treatment apparatus of the present invention can detect the amount of laundry prior to the input of the execution unit P47. This is possible because the laundry treatment apparatus of the present invention can detect the amount of laundry by rotating the drum less than one revolution. For example, the clothes handling apparatus of the present invention can detect the amount of clothes within 1 second and display information about the amount of clothes within 3 seconds.

However, the clothes handling apparatus according to the present invention may be configured to re-detect the amount of laundry whenever it detects that the door 132 opens or closes the opening 111 .

Opening and closing of the opening 111 by the door 132 may mean that clothes are additionally put into the drum 3 or clothes are taken out of the drum 3 through the opening 111. Because.

In other words, since there is a high possibility that the state inside the drum 3 has changed, the clothes handling apparatus of the present invention re-detects the amount of laundry every time the door 132 opens and closes the opening 111, and provides a response corresponding to the detected amount of laundry. Information can be displayed on the display unit P8.

In addition, the laundry treatment apparatus of the present invention may re-perform laundry amount detection whenever the power supply unit P46 is re-input and power is supplied to the control unit P again.

When the power supply to the control unit P is cut off as the power supply unit P46 is re-entered, the amount of fabric stored in the control unit P may be deleted. In addition, this is because there is a possibility that the control unit P may not recognize even though the internal state of the drum 3 is changed while the door 132 opens and closes the opening 111 in a state in which power supply to the control unit P is cut off.

That is, when the power supply unit P46 is input and the power supply to the control unit P is cut off, and the power supply unit P46 is input again and power is supplied to the control unit P again, the state inside the drum 3 in the meantime Since is likely to be variable, the clothes handling apparatus of the present invention can redetect the amount of fabric whenever the power supply unit P46 is repeatedly input, and display information corresponding to the detected amount of fabric on the display unit P8.

To this end, in the laundry treatment apparatus of the present invention, the locking unit (L) may wait until the execution unit (P47) is input without locking the door (132). As a result, the door 132 may open the opening 111 when the amount of laundry is sensed.

In addition, in the laundry handling apparatus of the present invention, when the power supply to the control unit P is cut off due to the input of the locking unit P46, the locking unit L may be controlled to unlock the door 132. As a result, when power is cut off, the door 132 may open the opening 111 .

However, in the clothes handling apparatus of the present invention, even if the door 132 opens and closes the opening 111 again or the power supply unit P46 is re-input to control unit P after power is cut off and then supplied again, the laundry amount of clothes is re-sensed. If the number of times exceeds the threshold value, the amount of clothes may not be detected again even if the power supply unit P46 is re-entered or the door 132 opens and closes the opening 111 again.

In other words, the laundry treatment apparatus of the present invention may be set to block the rediscovery of the laundry amount if the number of times the laundry amount is redetected prior to the input of the execution unit P47 exceeds a threshold value.

The fact that the laundry quantity detection was performed for the limit value means that the door 132 reopened and closed the opening 111 for the limit number of times, and the power supply unit P46 was re-entered the limit number of times or two times the limit number of times.

The limit value and the limit number of times may be set to the maximum number of times that can be reasonably determined that the user has added or withdrawn clothing. For example, the limit value and the limit number of times may be set to 10 times or more.

As a result, the clothes handling apparatus of the present invention opens and closes the door 132 a limited number of times or inputs the power supply unit P46 a limited number of times before the execution unit P47 is input or before the door 132 locks the opening 111. Since this is an abnormal situation, it is possible to prevent unnecessary laundry detection.

In other words, when the door 132 is opened and closed a limited number of times or the power supply unit P46 is input a limited number of times, it can be considered that clothes are not additionally drawn in and out of the drum 3 .

For example, it may be a situation in which a user, such as a child, accidentally presses the power supply unit P46 or repeatedly opens and closes the door 132 for fun.

In this case, by not automatically detecting the amount of laundry, the laundry treatment apparatus of the present invention can save energy and prevent an excessive load from occurring on the controller P or drive unit 32 .

Specifically, the laundry treatment apparatus of the present invention may perform a power input step (L1) in which a power command for supplying power to the control unit P is input through the power supply unit P46. Thereafter, the control unit P may perform a door sensing step (L2) of detecting whether the door 132 closes the opening 111 or not.

When the door 132 closes the opening 111, the laundry amount sensing step (L3) of detecting the amount of laundry by rotating the drum less than one rotation may be performed.

The laundry amount sensing step (L3) detects the amount of laundry through a current value applied or output when the drum is rotated less than one revolution, and the rotation angle of the drum is an angle at which clothes are separated from the inner wall of the drum or the arrangement of clothes is changed. It can be set below.

In the laundry amount detection step (L3), after the drum is rotated, the control unit P can calculate the amount of fabric within 2 seconds, and the information display step (L4) in which information related to the detected amount of fabric is displayed on the display unit P8 within 3 seconds. ) can be performed.

Thereafter, the control unit P detects whether the door 132 opens and closes the opening 111 before the execution unit P47 is input or the power supply unit P46 is re-input (L5) can be performed.

In the state detection step (L5), when the door 132 reopens and closes the opening 111 or the power supply unit P46 is input again to detect that power is cut off and then supplied again to the control unit P, the control unit P may perform a limit determination step (L6) of determining whether the number of times the amount of laundry is detected exceeds the threshold value (N).

If the number of times the amount of laundry is detected in the limit determination step (L6) does not exceed the threshold value (N), the control unit P performs the laundry amount detection step (L3) again, and then performs the information display step (L4) again. Existing information may be corrected to information corresponding to the redetected laundry weight.

On the other hand, if the number of times of detecting the amount of laundry in the limit judgment step L6 exceeds the threshold value N, the control unit P no longer performs the detection of the amount of laundry even if the door is reopened and closed and the power supply unit re-inputs. An ignoring step (L7) may be performed.

An execution input step (L8) in which the execution unit (P47) receives an execution command for executing the course and option selected by the operation unit (P7) while the ignoring step (L7) is being performed or the information displaying step (L4) is being performed. ) can be performed.

When the execution input step (L8) is performed, a door locking step (L9) in which the locking unit (L) locks the door (132) to the cabinet (1) to block the opening (111) from being opened can be performed

As described above, when the door 132 reopens the cabinet 1 or when the power supply unit P46 is re-entered and the power supply to the control unit P is cut off and then supplied, the clothes handling apparatus of the present invention detects the amount of laundry again. carry out

However, when the time between opening and closing the door 132 is much shorter than the time limit T required when clothes are put into the drum 3, the internal state of the drum 3 is less likely to change. In addition, when the power supply unit P46 is re-input and the time period during which power is re-supplied to the control unit P is much shorter than the time limit T in which clothes are put in, the internal state of the drum 3 is unlikely to change.

Accordingly, the clothes handling apparatus according to the present invention may not additionally perform the detection of the amount of laundry if the reopening/closing time of the door 132 or the re-entry time of the power supply unit P47 is less than the limited time T.

Accordingly, when the user accidentally opens and closes the door 132 and then quickly closes it, or when the power supply unit (P47) is accidentally input and then input again, the laundry treatment apparatus of the present invention cuts off the laundry amount detection and consumes unnecessary energy. can block

The controller (P) may be provided to detect a time interval between inputting and re-inputting the power supply unit (P46), and the door 132 is opened through the sensor unit (S) or the locking unit (L). It may also be provided to detect the time interval for opening and closing (111).

The time limit T may correspond to, for example, less than 1 second.

On the other hand, the sensor unit (S) is provided in the cabinet 1 to face the door 132 or to be adjacent to the door 132, and detects a signal such as a magnetic field generated from the door 132. It may be provided with a hall sensor or a reed switch, and the opening angle of the door 132 may be sensed by sensing the strength of the magnetic field.

For example, if the sensor unit S does not detect the magnetic field, it may be determined that the door 132 has opened the opening 111 beyond the input interval, which is the minimum interval at which clothes can be inserted. , When the magnetic field is sensed, it may be determined that the door 132 has opened the opening 111 within the input interval or less.

In addition, a sensor unit S may be provided at a hinge portion rotatably coupling the door 132 to the cabinet 1 to detect an opening angle of the door 132 .

As such, if the door 132 opens and then closes the opening 111 within the input interval, the clothes handling apparatus of the present invention determines that the internal state of the drum 3 has not changed and may not perform laundry amount detection.

The insertion interval may be set to less than 10 cm or the like.

Specifically, the laundry treatment apparatus according to the present invention may perform a power input step M1 in which a power command for supplying power to the control unit P is input through the power supply unit P46. Thereafter, a door sensing step M2 may be performed to detect whether the door 132 closes the opening 111 or not.

When the door 132 closes the opening 111, the laundry amount sensing step M3 may be performed by rotating the drum less than one revolution to detect the amount of laundry.

In the laundry amount sensing step (M3), the amount of laundry is detected through a current value applied or output when the drum is rotated less than one revolution, and the rotation angle of the drum is an angle at which clothes are separated from the inner wall of the drum or the arrangement of clothes is changed. It can be set below.

In the laundry amount detection step (M3), after the drum is rotated, the control unit P can calculate the amount of fabric within 2 seconds, and the information display step (M4) in which information related to the detected amount of fabric is displayed on the display unit P8 within 3 seconds. ) can be performed.

Thereafter, the control unit P detects whether or not the door 132 opens and closes the opening 111 before the execution unit P47 is input or the power supply unit P46 is re-input (M5) can be performed.

In the state detection step (L5), when the door 132 reopens and closes the opening 111 or the power supply unit P46 is input again to detect that power is cut off and then supplied again to the control unit P, the control unit P may perform a limit determination step (M6) of determining whether the time when the door 132 was reopened or the time when the power supply unit (P46) was repeatedly input is within a limited time.

If the reopening time of the door 132 or the time for which the power supply unit P46 is repeatedly input in the limit determination step M6 is longer than the time limit, the laundry amount detection step M3 is performed again, and the information display step M4 is performed again. ) may be performed to correct the existing information to information corresponding to the redetected amount of laundry.

On the other hand, if the time during which the door 132 was reopened or the time during which the power supply unit P46 was repeatedly input is shorter than the time limit T in the limit determination step M6, the control unit P may reopen and close the door. And, even if there is a re-input of the power supply unit, the ignoring step M7 in which the laundry weight is not performed any more can be performed.

In the limit determination step M6, it may be determined whether the degree of opening of the opening 111 by the door 132, the opening interval, and the opening angle are smaller than the input interval at which the clothes can be put in.

For example, the sensor unit S provided in the cabinet 1 may be provided to determine the degree of opening of the door 132 by calculating the degree of a detected value detected by a hall sensor or the like. A hinge provided in may be provided to detect an opening angle.

An execution input step (M8) in which the execution unit (P47) receives an execution command for executing the course and option selected by the operation unit (P7) while the ignoring step (M7) is being performed or the information displaying step (M4) is being performed. ) can be performed.

When the execution input step (M8) is performed, a door locking step (M9) in which the locking part (L) locks the door 132 to the cabinet 1 to block the opening 111 from being opened can be performed

As described above, when the door 132 is opened or closed or the power supply unit P46 is re-input, the clothes handling apparatus of the present invention detects the amount of clothes again, and the weight corresponding to the amount of clothes detected again, the course execution time, One or more of the amounts of detergent may be corrected and displayed.

However, the clothes handling apparatus of the present invention may block information corresponding to the amount of fabric displayed on the display unit P8 from being changed if the amount of change detected again is greater than the amount of fabric previously detected.

Specifically, the clothes handling apparatus according to the present invention may block information corresponding to the amount of fabric displayed on the display unit P8 from being changed if the change value of the amount of fabric is within the comparison value.

The comparison value may be set as a threshold value for changing the running time of a course corresponding to the previously detected laundry amount or the detergent amount.

For example, in the clothes handling apparatus of the present invention, if the detergent amount or course execution time is set to be different in the 3KG and 5KG sections, and the first laundry value is 4.4KG and the laundry value detected thereafter is 4.5KG, the detergent amount or execution time is changed. Therefore, it is possible to block information about the amount of laundry from being changed.

Accordingly, in the laundry treatment apparatus according to the present invention, it is possible to prevent unnecessary changes in contents displayed on the display unit P8. In addition, when the value of the fabric amount re-detected is different from the amount of clothes actually put in or taken out due to a detection error of fabric amount detection, detection distribution, etc., it is possible to prevent mistrust from being displayed to the user.

The laundry handling apparatus of the present invention may be provided to detect whether or not a change amount obtained by comparing the fabric amount detected again with the fabric amount detected immediately before is equal to or less than the comparison value.

In addition, the laundry handling apparatus of the present invention may be provided to detect whether or not a change amount obtained by comparing the redetected amount of fabric with the initially detected amount of fabric is equal to or less than the comparison value.

In addition, the laundry treatment apparatus of the present invention may be provided to determine whether or not the absolute value of the re-detected laundry amount exceeds the threshold range.

Specifically, the laundry treatment apparatus according to the present invention may perform a power input step N1 in which a power command for supplying power to the control unit P is input through the power supply unit P46. Thereafter, a door sensing step N2 for detecting whether the door 132 closes the opening 111 may be performed.

When the door 132 closes the opening 111, the laundry amount sensing step N3 may be performed by rotating the drum less than one revolution to detect the amount of laundry.

The laundry amount detection step (N3) detects the amount of laundry through a current value applied or output when the drum is rotated less than one revolution, and the rotation angle of the drum is an angle at which clothes are separated from the inner wall of the drum or the arrangement of clothes is changed. It can be set below.

In the laundry quantity detecting step (N3), after the drum is rotated, the control unit P can calculate the laundry quantity within 2 seconds, and the information display step (N4) in which information related to the detected laundry quantity is displayed on the display unit P8 within 3 seconds. ) can be performed.

Thereafter, the control unit P detects whether the door 132 opens and closes the opening 111 before the execution unit P47 is input or the power supply unit P46 is re-input (N5) can be performed.

In the state detection step (N5), when the door 132 reopens and closes the opening 111 or the power supply unit P46 is input again to detect that the power supply to the control unit P has been cut off and supplied again, the control unit P may perform a change determination step (N6) of detecting whether the amount of change exceeds a reference value or a threshold value by comparing the amount of fabric detected again with the amount of fabric previously or initially detected.

The change determination step (N6) can be regarded as a step of re-detecting the amount of fabric and comparing the re-detected amount of fabric with the previous amount of fabric.

If the amount of change is greater than or equal to the threshold value in the change determination step N6, the information display step N4 is performed again to correct the existing information to information corresponding to the redetected amount of linen.

On the other hand, if the change amount is less than the threshold value in the change determination step (N6), the control unit P performs an ignoring step (N7) in which the laundry amount detection is no longer performed even if the door is reopened and the power supply unit re-inputs. can do.

An execution input step (N8) in which the execution unit (P47) receives an execution command to execute the course and option selected by the operation unit (P7) while the ignoring step (N7) is being performed or the information displaying step (N4) is being performed. ) can be performed.

When the execution input step (N8) is performed, a door locking step (N9) in which the locking part (L) locks the door 132 to the cabinet 1 to block the opening 111 from being opened occurs. can be performed

On the other hand, in the change determination step (N6), the control unit P does not determine the amount of change, but determines whether or not the amount of laundry detected again exceeds or changes the critical section or critical range for changing the amount of detergent or execution time. It can be equipped to sense.

At this time, if the redetected amount of linen exceeds the threshold section or is placed in another threshold section, the displayed information may be changed in the information display step (N4).

However, at this time, if the redetected amount of laundry is within the threshold section, the ignoring step (N7) may be performed.

In the laundry treatment apparatus of the present invention, the door is not locked when the laundry amount is detected.

In other words, the locking part (L) of the laundry treatment apparatus of the present invention may be provided to lock the door only when the amount of laundry is detected. In addition, the locking unit (L) of the laundry treatment apparatus of the present invention may be provided to lock the door only when the execution unit (P47) is input.

As a result, the door of the clothes handling apparatus of the present invention can be opened when the amount of laundry is detected.

*If the door is opened during the fabric weight detection process, the fabric weight detection can be stopped.

Therefore, when the door is closed again, the laundry amount detection can be performed again.

However, when the largest amount of clothing, such as a blanket, is stored in the drum 3, the door 132 can be opened by slightly rotating the drum 3. Even at this time, if the laundry quantity detection is continuously attempted until the laundry quantity detection is completed, there is a high probability that the door will be opened, so washing may be delayed or washing itself may be impossible.

Accordingly, the clothes handling apparatus according to the present invention can quickly determine the amount of clothes and lock the door 132 to prevent the door from being opened when there is a large amount or the largest amount of clothes.

Specifically, the laundry handling apparatus of the present invention may determine whether the number of failures due to door opening is greater than the determined number of times when detecting the amount of laundry or if the detection of the amount of laundry fails due to door opening.

For example, if the number of door open failures during detection of the laundry amount is greater than the determined number of times, the laundry quantity of clothes may be determined as the maximum load and the door 132 may be locked. That is, laundry delay can be prevented by stopping the detection of the amount of laundry and performing washing based on the maximum load.

The confirmed number of times may be continuously occurring or may be the sum of intermittently occurring times. For example, the number of confirmations may be set to two or more.

Meanwhile, the clothes handling apparatus of the present invention may successfully detect the amount of fabric at least once when performing the detection of the amount of fabric, and the detected amount of fabric may be large. In this case, when the door 132 is reopened to additionally perform the laundry quantity detection, if the door is opened and the laundry quantity detection fails, the door 132 may be locked after determining the quantity of laundry.

That is, laundry delay can be prevented by stopping detection of the amount of laundry and performing laundry based on a large amount of load.

On the other hand, the clothes tuck device of the present invention may have a small amount of fabric sensed when performing the detection of the amount of fabric. In this case, when the door 132 is reopened, the amount of laundry can be detected each time.

In addition, when the door is reopened and detects an additional amount of fabric in a situation where a small amount of fabric is detected, if the sensor fails to detect the amount of fabric due to the opening of the door, it can be seen that the user opened the door rather than the clothes pushing the door. there is. Accordingly, the laundry treatment apparatus of the present invention can repeatedly perform the laundry quantity detection both in a situation where the laundry quantity detection fails when a small amount of laundry is detected and in a situation where the door is opened and then closed again after the laundry quantity detection is completed.

Specifically, the laundry treatment apparatus of the present invention may perform a power input step W1 in which a power command for supplying power to the control unit P is input through the power supply unit P46. Thereafter, a door sensing step W2 for detecting whether the door 132 closes the opening 111 may be performed.

When the door 132 closes the opening 111, the laundry amount sensing step W3 may be performed by rotating the drum less than one rotation to detect the amount of laundry.

After the fabric quantity detecting step W3 is performed, an open detecting step W4 for detecting whether the door is opened or closed again may be performed.

When the door is not additionally opened and closed and the laundry quantity detection is completed in the open detection step W4, the information displaying step W5 of displaying information corresponding to the detected laundry quantity on the display unit P8 may be performed.

Afterwards, or when the execution input step (W11) in which the execution unit (P47) receives an execution command for courses and options is performed, the locking step (W12) for locking the door 132 may be performed.

However, if it is detected that the door is opened and then closed again in the opening detection step W4, the laundry amount detection may be re-performed. At this time, if the detection of the amount of fabric fails due to the opening of the door, the detection of the amount of fabric may be attempted again.

Thereafter, a failure detection step (W6) may be performed to check whether or not the fabric quantity detection has failed more than the determined number of times (N). The failure detection step (W6) may be a step of continuously detecting whether or not the laundry amount detection has failed by the determined number of times (N). Alternatively, it may be a step of intermittently detecting whether or not the total laundry amount detection failure has reached the definite number N.

If the fabric quantity detection fails more than the number of times N determined, the largest quantity determination step W7 may be performed in which the laundry quantity detection is stopped and the maximum quantity is determined.

On the other hand, if the failure detection step (W6) fails by the number of times (N) or less, a fabric amount checking step (W8) may be performed to check whether or not the amount of fabric detected at least once is large. If the amount of fabric detected at least once is determined to be a large amount in the fabric amount checking step W8, the probability that the fabric amount is equal to or higher than that amount is high, and thus, the amount determining step W9 of determining the amount of fabric as a large amount may be performed.

If there is no case where a large amount is detected at least once in the fabric amount checking step (W8) or only a small amount is detected, the fabric amount sensing step (W3) may be repeatedly performed until the fabric amount detection is completed.

Meanwhile, when the maximum amount determining step W7 or the amount determining step W9 is performed, an information change step W10 may be performed to change or determine the determined amount of fabric to the detected amount. Thereafter, an information display step W5 of displaying information corresponding to the determined amount of laundry on the display unit P8 may be performed.

At this time, a door locking step (W12) of locking the door 132 to prevent discharge of clothes may be performed in advance.

Alternatively, the locking step (W12) of locking the door 132 may be performed immediately after the execution input step (W11) in which the execution unit (P47) receives the course and option execution commands is performed.

The present invention is not limited to the scope of its rights to the above-described embodiment that will be able to be practiced in various forms. 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.
