Definitions

  • the invention relates to a wet and dry vacuum cleaner with a collecting container for contaminated liquid, a suction unit for generating a suction pressure in the collecting container and with a suction line leading from a suction nozzle to the collecting container.
  • the wet and dry vacuum cleaners of this type are suitable for absorbing both contaminated liquid and dry dust.
  • the conversions on the device itself are annoying for the operator, and these conversions are often omitted, so that, with appropriate operation, performance reductions and even destruction, for example of a paper filter bag due to liquid, can result.
  • the cross section of the suction line is covered with a microfilter when the suction line exits the chamber. This ensures that no dust-like particles are sucked out of the chamber through the suction line, so that the suction unit is absolutely protected from dust particles.
  • the chamber can have an airtight sealable cover, which in the open state enables access to the interior of the chamber. Since the filter bag is usually held detachably at the end of the suction line, the filter bag can be removed when it is filled and replaced with an empty filter bag.
  • suction line is designed as a rigid tube in the region adjoining the chamber on both sides.
  • the suction line can have a releasable connection in the area between the chamber and the collecting container, which connection is preferably arranged in the tubular part of the suction line between the chamber and a handle for displacing the structural unit consisting of the suction nozzle, tubular suction line and chamber.
  • This assembly guided by the operator over the surface to be cleaned can thus be removed in a simple manner by loosening this connection and replaced by another assembly, so that the transition from the wet suction function to the dry suction function can be accomplished by this single action.
  • the wet and dry vacuum cleaner comprises, in a manner known per se, a dirt container which is sealed off from the outside and connected to a suction unit, through which a suction pressure is built up in the collecting container.
  • a suction line opens into the collecting container and is connected to the attachment shown in the drawing.
  • This front attachment comprises a tubular suction line 1, which connects a floor suction nozzle 2 with a suction hose, not shown in the drawing, which leads to the collecting container.
  • the tubular suction line has at its upper end a bend 3 to which the suction hose can be connected.
  • a handle 4 at the upper end of the tubular suction line 1, so that the suction nozzle 2 can be guided by means of this handle 4 over the tubular suction line 1 over the surface to be cleaned.
  • a chamber 5 which extends over a considerable part of this tubular suction line 1, is switched into the tubular suction line 1. It is an essentially cuboid chamber which is sealed airtight by means of a cover 6 which extends over its entire length. The lid is removable and can be closed in its closed position by means of latch 7 known per se (FIG. 2).
  • the tubular suction line 1 enters the interior of the chamber 5 on the suction nozzle side in the form of a pipe socket 8, at the opposite end of the chamber 5 the suction line 1 also forms a pipe socket 9 which protrudes slightly into the chamber 5.
  • the cross section of the pipe socket 9 is covered by a plate-shaped microfilter 11 which extends over the entire cross section of the chamber 5 and is detachably fastened in the chamber 5 in a suitable holder (not shown in the drawing).
  • another attachment can be used, for example a continuous suction line, not shown in the drawing, which is connected to a suction nozzle for wet operation.
  • the attachment shown in the drawing is used for dry vacuum operation.
  • a negative pressure is generated in the interior of the chamber 5 via the suction line 1, so that air is sucked in from the environment via the suction nozzle 2, which air enters the filter bag 10 and passes through it.
  • Any entrained dust particles are collected in the filter bag.
  • Any fine dust passing through the filter bag is additionally retained in the microfilter 11, so that an air stream cleaned of dust particles of any size enters the collecting container-side section of the suction line 1.
  • the filter bag 10 can be removed when it is filled, for this purpose the lid 6 is opened.
  • suction nozzle 2 If the operator wants to switch to wet suction, it is sufficient to separate the component consisting of suction nozzle 2, suction line 1 and chamber 5 by loosening the connection 12 from the manifold-near suction line part and the handle; a wet suction attachment can then be connected at this point, the in the described manner only has a continuous suction pipe and a wet suction nozzle. Further conversions or conversions of the wet and dry vacuum cleaner are not necessary for the transition from dry vacuuming to wet vacuuming.
  • the tubular suction line 1 extends obliquely from the suction nozzle 2 up to the handle 4, so that a rigid, easy-to-use unit is formed, which also includes the chamber 5 integrated into the suction pipe.
  • the chamber with the filter bag is not very heavy, ie the handling of this unit is not seriously hampered by the arrangement of the chamber and the filter in the suction pipe. It is particularly advantageous that no heavy suction units or similar machine parts are necessary in the chamber, since the suction air flow is generated in the wet and dry vacuum cleaner, which can be arranged stationary or guided on rollers. Only the dry dust collector is located in the chamber.
