Definitions

  • the present invention relates to a method used in vacuum cleaners for controlling the motor power by using pressure variations.
  • One of the user behaviors is that users are likely to leave the cleaner in running condition when not in actual use. This will cause high energy consumption and high noise level.
  • Another user behavior is that the user tends to rub the surface of the rug, bare floor, etc., unconsciously faster when dirt or stain is observed. In these conditions, if the motor power stays at a predetermined level there will be an unsatisfactory cleaning performance.
  • suction force of the vacuum cleaner is adjusted manually or automatically.
  • manual adjustment of suction force the user varies the speed of the motor by means of a potentiometer.
  • the adjusted power level may not be the optimum level for the vacuum cleaner. It is observed that the user tends to use maximum power under any circumstances since it is impossible for the user to truly determine the need for maximum power. Since using maximum power under all conditions is not usually necessary, selecting unnecessarily high power level causes high noise level and high energy consumption.
  • the object of the present invention is to develop a method to control the motor power according to user behavior.
  • the present invention is illustrated in the drawings, wherein:
  • Figure 1 - is the shematic view of a vacuum cleaner.
  • Figure 2 - is the flow chart of the control method.
  • Figure 3 - is a sample graph showing pressure values, mean pressure and crossings
  • vacuum cleaner (1) comprises a motor (3) that provides the suction, a nozzle (5) that contacts the surface in order to clean it, a pressure sensor (2) placed on the dust passageway to detect the pressure variations and a control means (4) that controls the motor (3).
  • the type of the surface that is being cleaned effects the pressure values measured by the pressure sensor (2).
  • a resistance such as a carpet, floor etc. air to be sucked lowers in amount. If the type of the surface to be cleaned is such that it covers the nozzle (5) totally, not allowing any air to pass through, the pressure level reaches vacuum.
  • the difference values ( ⁇ ,, ⁇ 2 , .... ⁇ n ) between the pressure values (P réelle P 2 , .... P n ) and the mean pressure (P mean ) are found (103). Then the changes of sign of consecutive difference values are determined and the number of sign changes is set as the number of crossings (C actua
  • mean pressure value (P mean ) is smaller than the predetermined reference pressure value (P ref ), it is decided that the user does not use the vacuum cleaner so the vacuum cleaner can go into a power saving mode and the motor (3) power is decreased to a predetermined stand-by power (114) and the new pressure values are gathered (101).
  • the vacuum cleaner is started again to operate with its regular motor power only by the user.
  • mean pressure value (P mean ) is greater than the predetermined reference pressure value (P ref )
  • mean pressure (P mean ) of the previous measurement cycle is used and the difference values ( ⁇ cellulose ⁇ 2 , .... ⁇ n ) between the pressure values (P Coordinat P 2 , .... P n ) and the mean pressure (P mean ) of the previous measurement cycle are found.
