Definitions

  • This application relates to a laundry treatment apparatus and a control method of the laundry treatment apparatus.
  • a laundry treatment apparatus includes a washing machine for washing objects such as clothes and a dryer for drying objects to be dried.
  • Conventional laundry treatment apparatuses for washing include a tub providing a space for storing water, a drum rotatably provided inside the tub and storing objects to be washed, a water supply unit supplying water to the tub, and supplying detergent to the tub. and a drainage unit for discharging the water stored in the tub to the outside of the tub.
  • the laundry treatment apparatus having the above-described structure supplies water and detergent to the tub through the water supply unit and the detergent supply unit, and then rotates the drum to remove foreign matters remaining in the object to be washed, and the water stored in the tub. Washing was performed by repeating a drainage process of discharging and a dehydration process of removing water remaining in the object to be washed by rotating the drum.
  • the bubbles generated in the process of separating foreign substances cause problems such as the discharge of bubbles to the outside of the tub, the problem of causing a large load to the driving unit that rotates the drum, and the problem of rotating the drum at a high rotational speed required for the dehydration process. , If the amount of foam can be measured or predicted relatively accurately, the above problem can be solved.
  • An object of the present application is to provide a laundry treatment apparatus capable of determining the water level inside the tub and the amount of bubbles generated inside the tub (bubble height, etc.) and a control method of the laundry treatment apparatus.
  • an object of the present application is to provide a laundry treatment apparatus equipped with an electrostatic sensor capable of determining at least one of a water level inside a tub and an amount of bubbles generated inside the tub, and a control method of the laundry treatment apparatus.
  • a tub providing a space for storing water; a drum rotatably provided inside the tub to store clothes; a water supply unit supplying water to the tub; a detergent supply unit supplying detergent to the tub; and a sensor capable of detecting a change in capacitance inside the tub body to detect at least one of a height of bubbles generated inside the tub body and a height of water stored in the tub body; a laundry weight detecting step of rotating the drum to determine the amount of clothes stored in the drum; a water supplying step of supplying water to the tub through the water supply unit according to the amount of laundry; a detergent supply step in which the detergent supply unit supplies detergent to the tub; a washing step of rotating the drum to remove foreign substances from clothes; and a measuring step of measuring, by the sensor, whether the capacitance inside the tub body increases and the duration of the increase in capacitance while the washing step is in progress.
  • the present application provides a laundry treatment apparatus capable of determining the water level inside the tub and the amount of bubbles generated inside the tub (such as the height of bubbles) and a control method of the laundry treatment apparatus.
  • the reference height may be set to one value, and the sensor 7 may be provided with one capacitance sensor positioned at the reference height.
  • the reference water level (L) is a minimum water level (L1) at which the lowest point of the circumferential surface of the drum body 21 is submerged, a highest water level (L3) set higher than the minimum water level, and between the minimum water level and the highest water level. It may be provided to include the intermediate water level (L2) located.
  • the highest water level L3 may be set to a water level lower than a horizontal line S2 passing through the center of the tub inlet 23 .
  • the control method comprises a laundry amount detection step (S10) of determining the amount of clothes stored in the drum 3 by rotating the drum 3, and supplying the tub 2 to the tub 2 through the water supply unit 4 according to the amount of clothes.
  • the water supplying step (S21) and the detergent supplying step (S22) may be executed independently of each other, or the detergent supplying step (S22) may be executed by the water supplying step (S21).
  • the state in which the capacitance inside the tub body 21 is equal to or greater than the reference capacitance (the height h of the bubble inside the tub body reaches the reference height H) and the capacitance is equal to or greater than the reference capacitance is the first criterion. If the time T1 continues or longer, the control method may execute a changing step S42 of changing at least one of the rotational speed and rotational direction changing period of the drum set in the washing step S30.
  • the changing step (S42) is a means for suppressing the further generation of bubbles as much as possible, the changing step (S42) is provided to lower the rotation speed of the drum or change the rotation direction change period of the drum to a longer period. This is preferable
  • the intermediate draining step (S43) is executed through the drainage part (6), and the resupplying step (S44) is performed through the water supplying part (4).
  • the intermediate draining step (S43) and the resupplying step (S44) may be executed after temporarily stopping the washing step (S30).
  • the control method executes the washing step (S30) and the measuring step (S40) until a preset time elapses.
  • the control method determines whether the time during the washing step (S30) has reached the set time (S45).
  • the rinsing step (S90) is performed after the completion of the dehydration step (S80) by supplying water to the tub 2 and rotating the drum 3 at a rotational speed that induces a centrifugal force of less than 1G. It may be provided as a step of separating detergent and foreign substances from clothes.
  • step S50 If many bubbles are detected in the observation motion execution step (S50), it may be difficult to increase the rotational speed of the drum to the preset spin-drying speed during the dewatering step (S80). This is because bubbles inside the tub 2 act as a load for the driving unit 33 . If a large amount of foam is detected in the observation motion execution step (S50), there is a high possibility that an error will occur during the execution of the dewatering step (S80). Only step S62 and the rinsing step S90 may be executed.
  • the dehydration step (S80) is performed due to bubbles. This will reduce the chance of errors occurring.
