Definitions

  • the sucked-in dust air flows through a filter made of paper or a fabric.
  • the filter dust bag must be cleaned or replaced at shorter or longer intervals, which requires a time-consuming operation.
  • vacuuming the coarse particles get into the dust bag with the dust and the removal of the same is cumbersome and unsanitary.
  • the invention relates to a filter device, in particular for vacuum cleaners, according to the preamble of patent claim 1.
  • the same is based on the task even with large dirt or Dust accumulation to ensure continuous operation, cleaning work to be carried out easily and quickly and optionally to let the flow of dust and coarse particles free or to remove the latter.
  • Another task is self-cleaning without opening the housing in which the filter is located.
  • l denotes an air guide tube serving in a conventional manner at the same time as a handle
  • 2 the suction nozzle to be guided over the surface to be cleaned
  • 3 the filter housing connected to the air guide tube l
  • l ⁇ the air guide tube, which is used for the not particularly illustrated hose and mobile Fan leads.
  • the filter housing 3 consists of at least two partially inserted housing parts 3 ⁇ , 3 Fig (Fig. 6), which have larger diameters than the air duct l.
  • the air guide tubes l, l ⁇ are connected.
  • the two parts 3 ⁇ , 3 ⁇ of the filter housing 3 can also be connected to one another by a ribbed screw sleeve 5 (FIG. 2) or with a direct injection molded internal or external thread.
  • this transverse axis 6 In the housing part 3 ⁇ is on a, this transverse axis 6, a flat, provided with holes 7, in the flow direction of the air flow, rigid filter disc 8 (Fig. 2) exchangeably mounted.
  • An end part of the axis 6 protrudes from the housing part 3 ⁇ and has a manual actuating member 9, so that the filter disk 8 can be rotated in the air flow direction indicated by arrows A.
  • the actuator 9 is in Fig. 2 and 5 a cylindrical head in Fig. 4, however, an angle lever 9 ⁇ .
  • an automatically acting diaphragm valve 10 In the area of the air flow inlet B, an automatically acting diaphragm valve 10 is fastened in the housing part 3 ⁇ by screws or rivets 11.
  • the membrane 10 Before the start of the passage of air and when decommissioning, the membrane 10 assumes the position shown in FIG. 2. If suction air gets into the filter housing 3, the diaphragm valve 10 is opened, as shown by the dashed lines in FIG. 2, and reaches the filter disk 8. Large particles carried along fall off the filter disk 8 and reach the collecting space l2, the bottom of which partly through the inner walls the housing parts 3 ⁇ , 3 ⁇ is limited. Fine particles, on the other hand, pass through the holes 7 of the filter disk 8. If the holes 7 are partially or completely blocked, the axis 6 is rotated by means of the actuating element 9 in relation to the position according to FIG. 2 by 180 degrees, so that the air flow from the rear side flows through the filter disc 8 and any foreign matter that obstructs the holes 7 completely or partially.
  • the filter housing 3 When the filter housing 3 is opened, the fan producing the air flow being switched off beforehand, the coarse parts located in the collecting space 12 can be easily removed.
  • the diaphragm valve 10 closes automatically in the position shown in FIG. 6 and prevents foreign bodies from falling back. In order to clean the filter disc, it is simply brought into the position according to FIG. 2 by means of the actuating element 9 or 9 ⁇ and the axis 6.
  • FIG. 2 shows the position of the filter disk, in which dust and coarse particles can be taken along by the air flow and pass through the filter housing, from which the latter pass through the air duct l ⁇ in the connected dust bag at the fan.
  • the filter device for vacuum cleaners is suitable for all kinds of private and industrial use and can be easily installed in both new and existing versions.
  • the filter disk 8 can be covered with a dry or wetted fabric web.
  • the fabric sheets must e.g. be attached by the frame of the filter disc.
  • the housing 3, 3 ⁇ is made of transparent, impact-resistant plastic, the amount and type of coarse parts can be determined without opening the filter.
  • the filter body 8 can be designed for coarse and fine filtering and the exchange of the same with other hole sizes can be carried out quickly and easily, in particular if the housing 3 is in three parts.
  • a second fine filter disc l3 is arranged in the housing part 3 ⁇ at a distance from the filter disc 8.
  • This fine filter disc l3 has tiny, small, not drawn holes.
  • the fine filter disk l3 is covered with a porous filter film made of paper or a fabric, which is also not particularly shown.
  • the peripheral side of the fine filter disk l3 is clamped between the contact sides l4 of the housing parts 3 ⁇ , 3 ⁇ and, in contrast to the filter disk 8, is stationary and removable. The latter is only used if necessary, especially for searching or Filtering of very fine particles used.
  • the actuator 9 for rotating the filter disc 8 is designed as a rotary switch.
  • l5 denotes a rotation lock against undesired rotation of the housing parts 3 ⁇ , 3 ⁇ to each other. These can be formed by a protruding, elastic cam on the housing part 3 ⁇ , which engages in a recess located on the housing part 3 ⁇ .
  • the valve 10 is again a conventional elastic membrane with three radial cuts.
  • the filter device can be used wherever the separation of solid particles in gaseous media is required.
  • the filter device can be assigned to any type of ventilation unit.
  • the filter device described is a small parts filter, in particular for vacuum cleaners and fans, and is preferably installed in a suction pipe, as shown in FIG. 1.
  • the same takes the entrained, mostly unintentionally sucked-in parts, such as jewelry, toy parts, screws, fibers, hair, dirt, etc., from the air flow and retains them in the housing 3.
  • the housing 3 is opened by a simple, opposite rotational movement of the housing parts 3 ⁇ , 3 ⁇ .
  • the anti-rotation lock l5 prevents the housing 3 from opening automatically during operation. Because the housing 3 is made of transparent, impact-resistant plastic, optimal control over the content is guaranteed without having to open the filter device.
  • the filter disk 8 is actuated from the outside with the actuating member 9 and, if necessary, cleans itself into the position shown in FIG. 1.
  • the membrane 10 acting as a valve closes automatically when the engine is switched off and prevents it from falling back into the air duct l ⁇ (Fig. l and 6).
