Definitions

  • This invention relates to a vacuum cleaner comprising a cleaning device used to clean a sensor particularly a dust sensor.
  • Dust sensors are formed of two main parts; namely a light emitting device and a light receiving device.
  • Light emitting device is emitting an infrared light beam or like and light receiving device is receiving light emitted by the light emitting device.
  • These devices are arranged in a predetermined position on the air passageway.
  • These light emitting and light receiving devices are placed across each other at fixed positions so that the change in light intensity indicates the amount of dust passing through the suction path.
  • the light received by the phototransistor is decreased so the performance of the dust sensing means is degraded.
  • two kinds of solutions were presented in previous studies;
  • a device providing the cleaning of light emitting and receiving elements comprises cover means for the light emitting and receiving elements. One end of each of these cover means is flush with an inside surface of suction member. There are ringshaped projection means formed on inside surface of the suction member adjacent to and upstream of the light emitting element and the light receiving element to increase the inflow speed of the air including particulate material through a space between the light emitting element and the light receiving element.
  • the projection means includes cuts which form diverging channels, each channel having side walls formed by the cuts, which diverge towards and aligned with one of the light emitting element and the light receiving element to further increase the speed of the air including particulate material passing over the cover means.
  • the object of the present invention is to provide a cleaning device for sensors of any type particularly for optical dust sensors used in vacuum cleaners.
  • Vacuum cleaner (10) comprises a vacuum cleaner body (9), a hose (8), a dust sensor including a light emitter (2a) and a light receiver (2b) located on the air passageway, a housing (1) for the dust sensor and a cleaning device (3) located in the housing (1) in order to clean light emitter (2a) and light receiver (2b) components.
  • the light emitter (2a) and the light receiver (2b) components are placed in a housing (1) on the inlet of the vacuum cleaner body (9) and the cleaning device (3) is placed in the outlet of the hose (8).
  • the canals (4) are placed preferably in reverse sides leading to opposite directions.
  • the cleaning device (3) has one or more pins (5) preferably cylindrical, that move within the canal (4) according to the movement of the cleaning device (3).
  • One or more cleaning members (6) preferably felts to clean the light emitter (2a) and the light receiver (2b) components and one or more holes (7) to let the light pass between the light emitter (2a) and the light receiver (2b) components, are arranged consecutively on the cleaning device (3).
  • Other embodiments might be realized with only one canal (4), one cleaning member (6) and one hole (7).
  • the cleaning devices (3) When the cleaning device (3) is rotated, the cleaning members (6) pass over the light emitter (2a) and the light receiver (2b) and rub them, as in Figure 1 and the adhered dust on the light emitter (2a) and the light receiver (2b) components are removed.
  • the light emitter (2a) and the light receiver (2b) to be operated correctly there should not be any portion of the cleaning member left (6) over them. Therefore when the cleaning device (3) becomes fixed as in Figure 2 , the light emitter (2a) and the light receiver (2b) face eachother since the holes (7) come over the light emitter (2a) and the light receiver (2b) components.
  • the dust sensor operates without any problem since the passageway of the light is open and the light emitter (2a) and the light receiver (2b) are cleaned.
  • the pin (5) When the cleaning device (3) is taken out by a movement in counterclockwise direction, the pin (5) also moves in the counterclockwise direction in the canal (4) and the cleaning members (6) pass over the light emitter (2a) and the light receiver (2b) components, cleaning the soil adhered on them.
  • only one canal (4) which comprises one pin (5) is located in the housing (1) and one cleaning member (6) is arranged on the cleaning device (3) leaving the rest of the cleaning device (3) empty.
  • the cleaning device (3) is rotated such that the cleaning member (6) passes over both of the light emitter (2a) and the light receiver (2b) components, the cleaning member (6) rubs the light emitter (2a) and the light receiver (2b) components and the cleaning device (3) becomes fixed, the hole (7) comes over the light emitter (2a) and the light receiver (2b) components and the passage of the light from light emitter (2a) to light receiver (2b) is provided.
  • the canals (4) are arranged on the cleaning device (3) and the pins (5) are located on the housing (1) in order to provide the movement of the cleaning device (3) within the housing (1).
  • the dust collected on the light emitter (2a) and the light receiver (2b) components does not reach a limit value and the performance loss during the waiting period for the manual cleaning of the light emitter (2a) and the light receiver (2b) is avoided.
