Definitions

  • the present invention relates to a cleaning module for use in a device with a hydroponic culture for cleaning and humidifying air in rooms, in particular in living spaces.
  • a disadvantage of such air cleaning devices is that the granules are heavily polluted and dry out in the medium term because of the direct supply of contaminated ambient air into the hydroponic culture. Both soiling and dehydration have a detrimental effect on the growth of the plants and the micro-life in the granules of the hydroponic culture, whereby the granules have a filtering effect with respect to the dust or dirt particles of the ambient air and biodegrade the filtered contaminations.
  • the present invention has for its object to provide a device with a hydroponic culture for cleaning and humidifying air in rooms, especially in living spaces, in which the medium-term contamination and dehydration of the granules is omitted and which is also inexpensive and efficient.

  • This counteracts the aforementioned medium-term contamination and drying of the substrate, since the water / air mixture can condense in the form of fine droplets on the substrate.
  • the device returns the enriched in the cleaning tank with the contaminated ambient air water back into the substrate to finally get rid of it by the substrate as the main and final filter biologically largely from the impurities.

  • the lid 8a is designed in such a way that it supplies the water 4b to the opening 10 with the filtering cleaning unit 12 inserted therein and allows it to flow into it. In this case, a largely continuous water film is formed on the filter of the cleaning unit 12.
  • the suction unit 20 sucks the contaminated ambient air to be cleaned through the cleaning unit 12 into the first tank space of the cleaning module.
  • the water film filters out the ambient air on the one hand, i. frees the ambient air from coarse dust or dirt particles, and on the other hand enriches the ambient air with water, i. moistens the sucked in ambient air.
  • the suction unit 20 sucks the sucked in the first container space, prefiltered and humidified ambient air through the opening 18 and at the same time in the second container space of the cleaning module. For this second container space, the suction unit 20 presses the ambient air through the said air outlet slots of the fourth container part 8d in the near-bottom region of the plant vessel into the substrate 4 and supplies the substrate with sufficient air and moisture.
  • the ambient air penetrates the substrate 4 to the outside.
  • the height of the substrate in the plant container is designed so that the filtered air is passed through the interstices of the expanded clay to the outside and thereby comes into contact with the surface of the expanded clay.
