Definitions

  • the present invention relates to a washing machine wherein the measurement of water level and unbalanced load is performed.
  • the level of the water received in the machine is determined by measuring the pressure of the air compressed inside the air trap, which is connected to the tub, as the manometric height of the water, rising in the tub, increases, and by comparing this pressure with the reference pressure value in the situation when the tub is empty.
  • the tube coming from the air trap and the tube coming from the vibration sensor are connected to the pressure sensor separately.
  • a valve which enables the tube coming from the air trap to be cut off when desired, is situated on the tube coming from the air trap.
  • the aim of the present invention is the realization of a washing machine wherein the measurement of the water level and of the unbalanced load amount is performed with low cost, and the risk of which being damaged by resonating due to unbalanced load is minimized.
  • the washing machine comprises an air trap which is used for performing the water level detection, a vibration transmitter which is used for performing the unbalanced load detection, a pressure sensor which detects the pressure values created by the air that is compressed in the air trap and in the vibration transmitter, and a control unit which controls the washing algorithms in accordance with the data received from the pressure sensor.
  • the control unit used in the washing machine of the present invention, increases the drum speed step by step during spin-drying.
  • the control unit calculates the ratio of the pressure value, transmitted from the vibration transmitter to the pressure sensor at each speed, to the pressure value, transmitted at the previous speed, and, by comparing the calculated ratio with the threshold ratio saved to its memory by the manufacturer, foresees the amount of displacement the tub will perform while resonating.
  • the control unit stops the spin-drying process. However, if the calculated amount of displacement is smaller than the displacement which causes the tub to hit the body, the spin-drying process is continued.
  • a single threshold ratio is saved in the control unit memory for all speeds whereat a comparison is performed between the ratio and the threshold ratio.
  • a different threshold ratio is saved in the control unit memory for each speed whereat a comparison is performed between the ratio and the threshold ratio.
  • the amount of displacement that corresponds to the first pressure value transmitted from the vibration transmitter to the pressure sensor is compared with the maximum amount of displacement that can be allowed for the tub to perform.
  • the washing machine (1) comprises a drum (2) wherein laundry is disposed, a tub (3) wherein the drum (2) moves, an air trap (4) wherein the air is compressed as the amount of water taken into the tub (3) increases, a vibration transmitter (5) wherein the air is compressed depending on the vibration of the tub (3), a pressure sensor (6) which reads the pressure that is created by the air compressed in the air trap (4) and in the vibration transmitter (5), and a control unit (7) which determines the water level and the unbalanced load amount by interpreting the data it receives from the pressure sensor (6) ( Figure 1).
  • the washing machine (1) of the present invention applies a washing algorithm which preferably comprises water intake, washing, discharge and spin-drying steps.
  • the control unit (7) continues the spin-drying process by deciding that the amount of displacement ( ⁇ x r ) the tub (3) will perform when the resonance is reached, is smaller than the maximum amount of displacement ( ⁇ x tr ) which is determined by the manufacturer and which can be allowed for the tub (3) to perform.
  • the decision, given for stopping the spin-drying process is provided to be given independently of the noise which occurs in the pressure values as a result of reading the data, received both from the vibration transmitter (5) and from the air trap (4), by a single pressure sensor (6).
  • a single threshold ratio (d tr ) is saved in the control unit (7) memory for all speeds (n h1 n, ) whereat a comparison is performed between the ratio (d,) and the threshold ratio (d tr ).
  • a different threshold ratio (d tr ⁇ ) is saved in the control unit (7) memory for each speed (n,) whereat a comparison is performed between the ratio (d,) and the threshold ratio (d tr ).
  • the ratio (d,) cannot be calculated to be compared with the threshold ratio (d tr ).
  • the amount of displacement ( ⁇ x) that corresponds to the first pressure value (P 1 ) transmitted from the vibration transmitter (5) to the pressure sensor (6) is compared with the maximum amount of displacement ( ⁇ x tr ) which is saved in the control unit (7) memory and which can be allowed for the tub (3) to perform.

Abstract

La présente invention porte sur un lave-linge (1), comprenant un tambour (2) dans lequel est disposé du linge, une cuve (3) dans laquelle se déplace le tambour (2), un siphon (4) dans lequel l'air est comprimé lorsque la quantité d'eau admise dans la cuve (3) augmente, un élément de transmission de vibration (5) dans lequel l'air est comprimé en fonction de la vibration de la cuve (3), un capteur de pression (6) qui lit la pression qui est créée par l'air comprimé dans le siphon (4) et dans l'élément de transmission de vibration (5), et une unité de commande (7) qui détermine le niveau d'eau et la quantité de charge déséquilibrée.
