Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged system or device.
  • FIG. 1 is a view illustrating a structure of a washing machine 100 according to an embodiment of the disclosure.
  • the washing machine 100 includes a drum 110 in which laundry is accommodated, a motor 120 configured to rotate the drum 110, a controller 130 configured to control rotation of the motor 120, a sensor 140 configured to detect a rotational speed of the drum 110, and a processing portion 150.
  • controller 130 and the processing portion 150 may be implemented with at least one processor.
  • the sensor 140 detects a rotation angle of the drum 110 in addition to the rotational speed of the drum 110.
  • the processing portion 150 may determine the mass of the laundry based on the rotational speed in first and second acceleration sections to be described later.
  • the rotational speed of the drum 110 is used.
  • the sensor 140 is a position sensor configured to directly detect the rotational speed of the drum 110, but is not limited thereto. Therefore, the sensor 140 may be any suitable sensor.
  • the processing portion 150 may typically include at least one processor 152 and a memory 154.
  • the processor 152 executes a computer program configured to process of controlling the rotation of the drum 110 and the motor 120 and configured to process of obtaining the mass of the laundry.
  • the memory 154 typically stores such computer programs and associated data.
  • the processor 152 outputs a signal for controlling the rotation of the motor 120 to the controller 130.
  • the controller 130 drives the motor 120 based on the control signal from the processor 152.
  • FIG. 1 illustrates that the controller 130 and the processing portion 150 are separate functional blocks, but may be implemented as a single functional block.
  • FIG. 2 is a view illustrating a profile 200 of intermittent driving of the motor 120 for obtaining a mass of laundry according to an embodiment of the disclosure.
  • a horizontal axis represents the time
  • a vertical axis represents the rotational speed of the drum 110.
  • the profile 200 includes a first constant speed section 211, a first acceleration section 212, a stop section 215, a second constant speed section 221, and a second acceleration section 222.
  • a sign of the rotational speed indicates a rotational direction of the drum 110. Therefore, from time 0 (zero) to the stop section 215, the drum 110 rotates in one direction, and thereafter rotates in the opposite direction.
  • the controller 130 controls the rotation of the motor 120 to allow an absolute value of the rotational speed of the drum 110 at the start of the first acceleration section 212 to be the same as an absolute value of the rotational speed of the drum 110 at the start of the second acceleration section 222 and to allow sings thereof to be opposite to each other.
  • FIG. 3 is a view illustrating a profile 300 of intermittent driving of the motor 120 for obtaining a mass of laundry according to an embodiment of the disclosure.
  • a horizontal axis represents the time
  • a vertical axis represents the rotational speed of the drum 110.
  • the profile 300 includes a first constant speed section 311, a first acceleration section 312, a second constant speed section 321, and a second acceleration section 322. Unlike the profile 200, the profile 300 does not include a stop section.
  • the constant speed section, the acceleration section, and the deceleration section may be provided prior to the first constant speed section 311. Accordingly, a position of the laundry in the drum 110 may be fixed in advance.
  • the controller 130 controls the rotation of the motor 120 to provide the first constant speed section 311, in which the rotational speed of the drum 110 is constant, prior to the first acceleration section 312 and to provide the second constant speed section 321, in which the rotational speed of the drum 110 is constant, prior to the second acceleration section 322.
  • FIG. 4 is a view illustrating an eccentric position due to uneven distribution of the laundry in the drum 110 according to an embodiment of the disclosure.
  • the drum 110 rotates about a rotation axis 410.
  • Laundry 420 in the drum 110 may have an uneven distribution as illustrated in FIG. 4 .
  • a center 430 of the drum 110 is also shifted from the rotation axis 410 due to the uneven distribution of the laundry 420.
  • an angle of the center 430 with respect to the reference line 440 corresponds to an eccentric position 450 caused by the uneven distribution of the laundry 420 in the drum 110.
  • the eccentric position 450 may be set in a range of 0 to 360 degrees.
  • the position of the drum 110 is represented by the eccentric position 450, which may be named as a phase.
  • a start time of the first acceleration section and the second acceleration section corresponds to two points in which the eccentric position 450 caused by the uneven distribution of the laundry 420 in the drum 110 is shifted by 180 degrees.
  • the eccentric position 450 at a start time of the first acceleration section 312 is 270 degrees
  • the eccentric position 450 at a start time of the second acceleration section 322 is 90 degrees. Therefore, the start time of the first acceleration section 312 and the second acceleration section 322 corresponds to the two points in which the eccentric position 450 caused by the uneven distribution of the laundry 420 in the drum 110 is shifted by 180 degrees.
  • a start time of the first acceleration section 212 and the second acceleration section 222 corresponds to two points in which the eccentric position 450 caused by the uneven distribution of the laundry 420 in the drum 110 is shifted by 180 degrees.
  • the drum 110 rotates n times (n: natural number) in the first acceleration section and the second acceleration section.
  • n natural number
  • the drum 110 rotates once in the first acceleration section 312 and the second acceleration section 322, but it is not limited thereto. Therefore, as long as the number of rotation of the drum 110 in the first acceleration section 312 is the same as the number of rotation of the drum 110 in the second acceleration section 322, the drum 110 may rotate n times (n: natural number) other than once.
  • the number of rotation" of the drum represents the number of times in which the drum rotates. For example, the drum 110 may rotate two times in the first acceleration section 312 and the second acceleration section 322.
  • the processing portion 150 obtains the mass based on the mass detected in the first and second acceleration sections.
  • the acceleration in the first and second acceleration sections depends on the mass of the laundry 420.
  • the processing portion 150 may obtain the mass of the laundry 420 based on the increase amounts of the two rotational speeds in the first and second acceleration sections.
  • an angle of the rotation axis of the drum 110 of the washing machine 100 according to the disclosure with respect to the horizontal direction is from 0 (zero) degree to 45 degrees.
  • a washing machine operated in this range includes a washing machine that is commonly referred as "a drum type washing machine".
  • the rotation axis of the drum 110 is relatively close to the horizontal direction. Accordingly, due to the gravity, the rotational speed may be reduced when the eccentric position 450 moves up and the rotational speed may be increased when the eccentric position 450 moves down. Even when such a variation in the rotational speed occurs, it is possible to obtain a value closer to the true mass of the laundry 420 based on the two mass values of the laundry 420 obtained separately in the first acceleration section and the second acceleration section, which will be described later.
  • the start time of the first acceleration section 312 and the second acceleration section 322 corresponds to the two points in which the eccentric position 450 caused by the uneven distribution of the laundry 420 in the drum 110 is shifted by 180 degrees, it is possible to reduce an error that may occur when detecting the mass of the laundry 420.
  • This effect is also obtained in the example of FIG. 2 . It is appropriate to determine the mass of the laundry 420 based on an average of two masses detected in the first and second acceleration sections. Accordingly, the processing portion may more reduce the error that may occur when detecting the mass of the laundry 420.
  • the imbalance is a parameter determined by a weight corresponding to the uneven distribution of the laundry 420 in the drum 110 and a distance of the laundry 420 from the rotation axis 410. As the weight and the distance are increased, the imbalance may be increased.
  • a stop section of the motor 120 is generated. In the stop section, the centrifugal force is lost, and the laundry 420 attached to the side of the drum 110 falls down in the vertical direction and thus the arrangement of the laundry 420 may be changed.
  • the eccentric position and the unbalance amount change.
  • the eccentric position is corrected by monitoring the phase of the rotational speed or the like, but the imbalance is not corrected. Therefore, the profile 200 has a larger deviation than the profile 300.
  • the profile 300 is more appropriate than the profile 200.
  • the first acceleration section 312 and the second acceleration section 322 are generated during continuous driving of the drum, and the rotational speed of the drum is maintained at 30 rpm or more in the first acceleration section 312 and the second acceleration section 322.
  • Rpm may mean revolutions per minute of the motor and the drum.
  • the movement of the laundry 420 in the drum 110 may be reduced between the first acceleration section 312 and the second acceleration section 322.
  • the error at the detection of the mass of the laundry 420 may be reduced.
  • the start time of the first acceleration section (for example 312) and the second acceleration section (for example 322) corresponds to the two points in which the eccentric position 450 caused by the uneven distribution of the laundry 420 in the drum 110 is shifted by 180 degrees. Therefore, it can be detected that the phase of the eccentric position 450 is shifted by 180 degrees at the start time of the first acceleration section and the second acceleration section.
  • the processing portion 150 obtains the two points, in which the phase is shifted by 180 degrees, based on the rotation angle of the drum 110.
  • the rotation angle of the drum 110 may be detected by the sensor 140. More particularly, the difference between the rotation angle of the two points, in which the phase is shifted by 180 degrees, corresponds to (n + 0.5) rotation (n: natural number).
  • the phase detection of the start time based on the rotation angle may be performed in such a way that an angle at the start time of the first acceleration section is stored and then the second acceleration section starts at a timing in which the rotation angle is shifted by 180 degrees from the stored angle.
  • phase detection of the start time based on the rotation angle is more accurately performed in the embodiment using the profile 300 (continuous driving).
  • the processing portion 150 obtains the two points, in which the phase is shifted by 180 degrees, based on at least one of the rotational speed of the drum 110, a current flowing in the motor 120, and a voltage applied to the motor 120. More particularly, in the two points in which the phase is shifted by 180 degrees, a phase difference of one of the rotational speed of the drum 110, the current flowing in the motor 120, and the voltage applied to the motor 120 is 180 degrees.
  • the eccentric position 450 may be obtained from the phase of the sine wave waveform indicating the variation of the rotational speed. As the uneven distribution of the laundry 420 in the drum 110 is reduced, the amplitude of the waveform is reduced and the phase detection is difficult.
  • the controller may start the second acceleration section at a timing that is shifted by 180 degrees from the start time of the first acceleration section.
  • the current flowing in the motor 120 and the voltage applied to the motor 120 also vary in the constant speed section. Therefore, by using any one of the current flowing in the motor 120 or the voltage applied to the motor 120, it is possible to detect the phase at the start time in the same manner.
  • the current flowing in the motor 120 and the voltage applied to the motor 120 may be detected by the controller 130.
  • FIG. 5 illustrates a flow chart according to an embodiment of the disclosure.
  • the senor may detect the rotational speed of the drum (1001).
  • the processor may control the drum by controlling the motor, and the drum may be driven in the first acceleration section (1002).
  • the processor may determine the mass of laundry corresponding to the first acceleration section (1003).
  • the processor may perform the second acceleration section by controlling the motor at a point shifted by 180 degrees from the phase of the laundry at the start time of the first acceleration section (1004).
  • the processor may determine the mass of the laundry corresponding to the second acceleration section (1005).
  • the processor may determine the final mass of the laundry based on an average of the mass of the laundry obtained in the first acceleration section and the mass of the laundry obtained in the second acceleration section (1006).
  • the washing machine may more accurately measure the mass of laundry even when an imbalance of laundry occurs.
  • Each of the various functions in the disclosure may be realized by a single element or may be realized by a plurality of elements. Conversely, multiple functions may be realized by a single element. Each function may be realized by hardware, software, or a combination of hardware and software.
  • the flowchart in the disclosure includes a plurality of blocks. The processing of these blocks may be performed serially or in parallel. Also, the order of some blocks may be changed.
