Definitions

  • the invention relates to a method for cleaning the interior of pipes of ventilation and air conditioning systems.
  • the invention also relates to a cleaning device, in particular for use in such a method.
  • the DE 20 2019 000 152 U1 relates to a cleaning device for cleaning pipes of ventilation or air conditioning systems.
  • a so-called pig is used, which consists of one or more parts that are held together by a rope or a flexible axle.
  • the object of the present invention is to create a method of the type mentioned at the outset which avoids the disadvantages of the prior art, in particular enables a thorough cleaning of pipes even in the private sector.
  • pipes of ventilation and air conditioning systems can be thoroughly cleaned, with effective and verifiable disinfection also taking place.
  • the at least one first and / or second sterile carrier element can be a sterile compress.
  • a sterile compress or the like can be wrapped around the cleaning device as a carrier element and sucked through the pipe to be cleaned using the vacuum method. Due to the nature of the cleaning device, the sterile compress is pressed against the pipe wall and thus absorbs the contamination. When removing the cleaning device with the contaminated compress, attention should be paid to cleanliness so that a contact sample can then be taken from the contaminated compress.
  • the first contact sample can be used - for example by an external laboratory - to determine how high the total contamination of the pipe was before cleaning.
  • an external laboratory can also use the second or last contact sample to demonstrate how successful the cleaning and disinfection by the method according to the invention was.
  • the contamination by yeasts, molds and germs should be significantly reduced or no longer detectable.
  • the at least one first and / or second cleaning element can be designed as a microfiber cloth.
  • Microfiber cloths have a greatly increased cleaning efficiency for various types of soiling. Microfibre cloths can also be used to clean relatively residue-free and in almost all applications without the need to use harsh cleaning agents; water is usually sufficient to moisten the cloth. In the present case, for example, a vinegar cleaner can be used to achieve a very thorough cleaning effect on the pipes.
  • the inner area or a part of the inner area of the at least one pipe can be detected before method step a) in order to determine a degree of contamination and / or possible damage, in particular as a visual inspection of the at least one pipe ascertain.
  • the process steps c) and d) can be repeated one after the other until a desired or predetermined reduction in the degree of soiling, in particular a reduction in the infestation of germs and fungi, has been achieved.
  • the at least one sensor can be designed as a camera.
  • a vacuum cleaner can be connected to a first end of the at least one tube, in particular via an adapter, preferably made of silicone, in order to generate the required pressure difference.
  • the vacuum cleaner can be suitable for dust class H (highly hazardous dusts).
  • a vacuum of at least 160 mbar can be generated by the vacuum cleaner.
  • a class H vacuum cleaner can be used to clean the pipes. If the at least one pipe is possibly contaminated by mold, it can thus be ensured that the mold is properly vacuumed off and also remains in the vacuum cleaner. Using an unsuitable vacuum cleaner can spread the mold further into the air.
  • the vacuum cleaner should create a vacuum of at least 160 mbar in order to ensure that the cleaning device does not get stuck in the pipe.
  • a vacuum cleaner adapter can be used, which is especially made individually for the respective pipe, also preferably made of silicone. Silicone has high non-stick properties, is dishwasher safe and can therefore be used multiple times. In addition, silicone has high dimensional stability over a long period of time (sustainability) and high chemical resistance to aggressive media such as disinfectants and cleaning agents.
  • the cleaning device can have at least one magnetic or magnetizable or magnetically attractable element, in particular a magnetic metal disk, preferably in the area of the base and / or the top surface.
  • the at least one metal disk can be arranged parallel to the top surface or the base surface.
  • a metal disk can be incorporated into the cleaning device at the top and / or bottom.
  • a magnetic element that attracts the at least one magnetic or magnetizable or magnetically attractable element can be arranged on a push or pull cable which is introduced into the pipe in an emergency.
  • the push or pull cable can be formed from glass fiber or glass fibers.
  • the magnetic or magnetizable element of the cleaning device can have an at least partially blasted surface and / or be provided with one or more recesses or holes.
  • the metal disk can be blasted (e.g. by sandblasting or the like) in order to enlarge its surface and thus to ensure better adhesion or connection with the silicone.
  • recesses or holes can also be provided in the pane in order to further improve the connection with the silicone and thus to extend the service life of the cleaning device.
  • the adapter can have at least one passage, in particular for a push or pull cable, which is preferably formed by a tubular element incorporated in the adapter.
  • a bushing in particular a tube, through which the push or pull cable can be guided, can be incorporated into the vacuum cleaner adapter.
  • the magnetic push or pull cable arrangement and the suction power (negative pressure) of the vacuum cleaner can be used in combination to remove a stuck cleaning device or other stuck, especially magnetic objects from the pipes to be cleaned.
  • vacuum cleaner is connected in the technical or boiler room or in the room in which the central unit of the air conditioning or ventilation system is located in order to direct the contamination from the rooms or living spaces there.
  • the cleaning device can be wrapped with the at least one first and / or second sterile carrier element and / or with the at least one first and / or second cleaning element.
  • the cleaning device can be cylindrical and / or have a plurality of circumferential elastic lamellae in its outer surface or jacket surface, and / or be made in one piece, and / or be at least partially or completely made of silicone.
  • the cleaning device is made of silicone, it can ideally adapt to the shape of the pipe to be cleaned. Silicone has high non-stick properties and is dishwasher safe. Furthermore, it has a high dimensional stability over a long period of time and a high chemical resistance to aggressive media. Due to its shape and the adaptable size of the lamellas, the cleaning device is ideally placed in the recesses of the pipe to remove the dirt there without damaging any antibacterial coating on the pipes. Due to its shape and texture, the cleaning device is ideally suited as a carrier for sterile compresses or microfibre cloths in order to gently press them against the pipe walls. So optimal cleaning results are achieved or the disinfectant is applied to the entire surface of the pipe. As a result, complete and area-wide cleaning and disinfection are achieved.
  • Claim 12 specifies a cleaning device, in particular for use in a method for cleaning the interior of one or more pipes of ventilation and air conditioning systems.
  • the circumferential elastic lamellae can be formed by alternating elevations and depressions of the lateral surface that extend in the radial direction.
  • Figure 1 shows a cleaning device 1, in particular for use in a method for cleaning the interior of one or more pipes, not shown, of ventilation and air conditioning systems, which is designed in the shape of a cylinder and has a plurality of circumferential elastic lamellae 2 in its outer surface 3.
  • the cleaning device 1 can be designed in one piece and / or at least partially or completely made of silicone.
  • the circumferential elastic lamellae 2 are, as from Figure 1 can be seen, formed by alternating elevations 3a and depressions 3b of the lateral surface 3 extending in the radial direction.
  • FIG. 14 is a side view of the cleaning device of FIG Figure 1 shown, the lowermost recess 3b of the lateral surface 3 only in Figure 2 is shown.
  • the at least one first and / or second sterile carrier element can be a sterile compress.
  • the at least one first and / or second cleaning element can be designed as a microfiber cloth.
  • the inner area or a part of the inner area of the at least one tube can be detected before method step a) in order to determine a degree of contamination and / or possible damage to the at least one tube.
  • Process steps c) and d) can be repeated one after the other until a desired or predetermined reduction in the degree of soiling or the contamination has been achieved.
  • the at least one sensor can be designed as a camera.
  • a vacuum cleaner can be used, in particular via an adapter 4 (see FIG Figure 3 ), are connected to a first end of the at least one pipe in order to generate the pressure difference.
  • the vacuum cleaner is thus provided for guiding the cleaning device 1 through the at least one pipe by means of the pressure difference.
  • the vacuum cleaner can be suitable for dust class H (highly hazardous dusts).
  • a vacuum of at least 160 mbar, e.g. B. 256 mbar can be generated.
  • the cleaning device can be wrapped with the at least one first and / or second sterile carrier element and / or with the at least one first and / or second cleaning element.
  • the cleaning device 1 can be cylindrical and / or have a plurality of circumferential elastic lamellae 2 in its outer surface or jacket surface 3 and / or be made in one piece and / or at least partially or completely made of silicone.
  • FIG. 11 shows a simplified side sectional view of the cleaning device 1 ′ along the line AA in FIG Figure 4 .
  • the cleaning device 1 ' can have at least one magnetic or magnetizable or magnetically attractable element, in particular one in Figure 4
