  • the control method may then proceed to an operation of supplying water to the first reservoir 3 using the water supply unit (S20).
  • the operation of supplying water (S20) may be implemented as water is supplied to the first reservoir 3 through the supply pipe 71.
  • control method may then proceed to a primary reservoir washing operation S30 for washing the reservoirs 3 and 5 by producing a water stream.
  • the primary reservoir washing operation S30 may be implemented via the combination of a first motion, which rotates the pulsator body 61 to produce a water stream, and a second motion which rotates the second body 51 to produce a water stream.
  • the first motion (referred to as an “agitation motion”) is a motion that produces a water stream to move water from the bottom surface of the first body 31 to the top of the first body 31.
  • the controller may control the alternate implementation of clockwise rotation and counterclockwise rotation of the pulsator body 61.
  • the first motion is a motion that maintains a water stream moving from the bottom surface of the first body 31 to the first opening 35
  • the first motion may be referred to as a motion that produces a water stream suitable for the separation of impurities adhered to the bottom surface of the first body 31 and the bottom surface of the second body 51.
  • the second motion (referred to as a “wave force motion”) is a motion that produces a water stream to cause water, discharged out of the second body 51, to move upward along a space between the inner circumferential surface of the first body 31 and the outer circumferential surface of the second body 51 and thereafter be reintroduced into the second body 51 through the second opening 53.
  • the controller may rotate only the second body 51, or may rotate the second body 51 and the pulsator body 61 in the same direction at the same time.
  • the second motion includes the simultaneous rotation of the second body 51 and the pulsator body 61 will be described.
  • the water directed to the cover 33 by centrifugal force may move to the first opening 35 under the guidance of the guides 37, and may then be introduced into the second body 51 through the second opening 53 which is located under the first opening 35.
  • the water stream produced by the second motion may be suitable for the separation of impurities adhered to the bottom surface of the first body 31 and the bottom surface of the second body 51 as well as for the separation of impurities adhered to the circumferential surface of the first body 31 and the circumferential surface of the second body 51.
  • the washing force which is required to separate the impurities from the first body 31 and the second body 51, should increase as the flow rate of the water stream moving along the space between the inner circumferential surface of the first body 31 and the outer circumferential surface of the second body 51 increases.
  • the controller may control the second body 51 and the pulsator body 61 so that they are rotated in the same direction, and the number of revolutions per minute of the second motion may be set to be higher than the number of revolutions per minute of the first motion.
  • the first motion and the second motion may be alternately performed. That is, in the primary reservoir washing operation S30, the first motion may first be performed and then the second motion may be performed, or the second motion may first be performed and then the first motion may be performed.
  • the number of revolutions per minute of the second body 51 and the pulsator body 61 in the second motion may be higher than the number of revolutions per minute of the pulsator body 61 in the first motion. Therefore, performing first the first motion and then the second motion may be advantageous because it reduces the load on the drive unit 57 and the pulsator drive unit 63, 65 and 67.
  • the primary reservoir washing operation S30 may be implemented in the sequence of the second motion, the first motion, and the second motion. Since the washing force and washing range of the second motion are higher and wider than those of the first motion, implementing a greater number of repetitions of the second motion than the first motion may be advantageous for the washing of the reservoirs 3 and 5. However, since the load on the drive unit 57 and the pulsator drive unit 63, 65 and 67 should increase in the case where only the second motion is performed, sequentially repeating the second motion, the first motion, and the second motion may be advantageous in order to enhance washing force and to control the load of the drive units.
  • control method proceeds to an operation of discharging the water stored in the first body 31 to the outside of the cabinet 1 via the drain unit (S40, a primary drainage operation).
  • the impurities, separated from the respective bodies 31 and 51 in the primary reservoir washing operation S30, are discharged outward, along with the water inside the first body 31, through the drain pipe 81 connected to the bottom surface of the first body 31.
  • the impurities separated from the first body 31 and the second body 51 in the primary reservoir washing operation S30 may remain on the respective bodies 31 and 51, rather than being completely discharged via the primary drainage operation S40.
  • control method proceeds to a secondary reservoir washing operation S50 of spraying water using the sprayer 9.
  • the secondary reservoir washing operation S50 (referred to a “jet spray motion”) is an operation of additionally washing the reservoirs 3 and 5 and discharging the impurities, separated from the surfaces of the respective reservoirs 3 and 5 in the primary reservoir washing operation S30, to the outside of the first body 31 (i.e. rinsing).
  • the secondary reservoir washing operation S50 may include spraying water into the second body 51 using the sprayer 9 (S53), discharging the water, sprayed from the sprayer 9, to the outside of the first body 31 (S55, a secondary drainage operation), and rotating the second body 51 (S51).
  • the spraying operation S53 and the secondary drainage operation S55 may be implemented at the same time. That is, the secondary reservoir washing operation S50 may include a time period during which the spraying operation S53 and the secondary drainage operation S55 are performed at the same time (in terms of rinsing performance enhancement).
  • the sprayer 9 is configured to spray water only to a given region of the second body 51, and therefore, the rotating operation S51 serves to minimize the amount of impurities that remain on the second body 51 in consideration of the fixed spraying range of the sprayer 9.
  • the rotating operation S51 applies centrifugal force to the water discharged from the second body 51 to the first body 31 through the through-holes 55, the water supplied from the sprayer 9 to the second body 51 may hit the surface of the first body 31. Accordingly, the rotating operation S51 serves not only to enhance rinsing performance, but also to enhance the washing performance of the reservoirs 3 and 5.
  • the number of revolutions per minute of the second body 51 may be set to be lower than the number of revolutions per minute of the first motion and the number of revolutions per minute of the second motion.
  • the secondary reservoir washing operation S50 may include a time period during which the spraying operation S53, the secondary drainage operation S55, and the rotating operation S51 are performed at the same time.

Abstract

L'invention concerne un procédé de commande pour un appareil de traitement du linge, qui comprend un premier réservoir configuré pour contenir de l'eau et définissant une première ouverture pour recevoir du linge à travers celle-ci, un deuxième réservoir placé à l'intérieur du premier réservoir et définissant une deuxième ouverture, et un pulsateur disposé de manière rotative à l'intérieur du deuxième réservoir, le procédé consistant à fournir de l'eau au premier réservoir et à exécuter un lavage primaire des premier et deuxième réservoirs en faisant tourner le pulsateur ou le deuxième réservoir. L'étape de lavage primaire consiste à effectuer un premier mouvement en faisant tourner le pulsateur pour produire un flux d'eau à l'intérieur des premier et deuxième réservoirs, et à effectuer un deuxième mouvement en faisant tourner le deuxième réservoir pour amener l'eau à se déplacer vers le haut le long d'un espace entre une surface circonférentielle interne du premier réservoir et une surface circonférentielle externe du deuxième réservoir et l'introduire ensuite dans le deuxième réservoir à travers la deuxième ouverture.
