Definitions

  • the invention relates to an installation device for sensors and sensors according to the preamble of claim 1.
  • the invention relates to an installation device for optical dust detection means, for example in the form of the pairing of light emitting diode / phototransistor in vacuum cleaners, and therefore this area is discussed in more detail below, but it is understood that the invention is not restricted to this.
  • a manual cleaning of the sensor surfaces is not excluded, but not always possible, for example not if, when applied to the vacuum cleaner area, the optical dust detection means are located on both sides of a longer, narrow channel, i.e. at an installation location where you can use your fingers or a device or can only access it to a limited extent. In addition, it is not to be expected that such a cleaning will be carried out under all circumstances.
  • the invention is therefore based on the object Installation device for sensors of any kind and especially for the optical dust detection means to create a vacuum cleaner, which is designed so that an automatic cleaning takes place by itself.
  • the installation device solves this problem with the characterizing features of the main claim and has the advantage that an effective automatic even with any design of the sensitive area of the sensor, so even in cases where this area does not immediately transition into the adjacent wall Cleaning and blowing free in the sensitive area is possible, taking advantage of overpressure or underpressure of the ambient air at the installation site.
  • the invention thus makes use of the respective pressure difference in order to conduct air volumes or air flows on and along the sensor via longitudinal channels which are guided in the area of the installation site adjacent to the sensors so that its sensitive area during normal operation of the system, in which there is the sensors are located, by blowing on or at least flowing past air quantities in each case free or blown free.
  • the measures listed in the subclaims permit advantageous developments and improvements of the installation device specified in the main claim.
  • the construction of the installation device in one piece with the surrounding tube wall is particularly advantageous, so that the installation device, for example, forms a cylindrical protuberance, which receives the cylindrical, rotationally symmetrical sensor in its inner bore, but at the same time realizes longitudinal channels around the sensor, for example by forming a distance in certain peripheral areas, which when used on the suction channel of a vacuum cleaner from the inside of the pipe are open to the outside of the tube, so that air flows through these longitudinal channels due to the vacuum developed by the vacuum cleaner in the intake manifold, which for the vacuum cleaner itself represent external air or false air, but are so small that they play no role, but on the other hand for the air currents swept sensors and their sensitive areas are particularly important with regard to the cleaning effect thereby developed.
  • the basic idea of the present invention is to utilize or generate negative pressures or excess pressures present in the installation area of sensors, and to form air flows along the sensors and via their sensitive areas with the formation of longitudinal channels, which in particular also include the sensitive areas of the sensors cause that they have a constant cleaning effect.
  • optical dust detection means consisting of a light-emitting diode and a photo transistor in the suction tube of a vacuum cleaner; part of the remote intake manifold is designated by 10 in FIG. 1; the installation location for the sensor or sensors bears the reference symbols 11 or 11a, 11b.
  • optical dust detection means for example opposite one another a light transmitter 12 as a light emitting diode and a light receiver 13 as a photo transmission arranged and held so that their sensitive areas face each other, that is, the phototransistor receives the radiation emanating from the light transmitter, each interrupted by dusts and dirt particles carried in the direction of flow along the arrows A, so that a dust detection signal is generated as a result and with the help of suitable downstream evaluation
  • sensors In order to prevent the danger that, as the illustration in FIG. 2 also shows, sensors generally designed in a non-flush manner, but of any shape in their sensitive area in general, that is to say here the light-emitting diode and the phototransistor, are increasingly covered by the dirt particles and dusts , which are at any point in the suction channel, but preferably at these edges, breaks, protruding parts and the like.
  • the mounting device for the sensor is designed such that at least one longitudinal channel 14 open from the outside is provided, in the illustrated embodiment, as shown in FIG.
  • Installation device preferably as a one-piece protuberance or as a cylindrical extension from the suction channel tube wall extending receiving part with an internal passage, which receives the sensor, that is, the light emitting diodes or the phototransistor in the present case.
  • the sensor that is, the light emitting diodes or the phototransistor in the present case.
  • axial wall parts 15 located at a distance from one another on the outer wall of the sensor bear directly against the outer wall of the sensor, the special configuration or shape of the (remaining) axial channels 14 which also form any desired shape between them. Wall pieces can be shaped as desired.
  • An advantageous embodiment of the present invention can consist in the fact that in the case of tapering sensor surfaces or such sensitive sensor regions which are essentially flush with the surface of the inner tube wall and which guide the air flows Axial channels 14 towards the inside, i.e. where they open into the free interior of the suction channel adjacent to the sensitive areas of the sensors, have bevels 17 which, as can also be seen from the dashed lines of the arrows, center the air flows more strongly, i.e. on the Open up the middle area of the sensor (sensitive area) and support effective cleaning.
  • These bevels can be referred to as baffles, which ensure that the air flows generated by the negative pressure are deflected, particularly into the sensitive area of the dust detection means.
