Definitions

  • the present invention relates to a machine tool that can be connected to an elongated tool that extends forward in a spatial direction, the machine tool being set up to drive the tool to a rotating and/or striking movement.
  • the machine tool includes a dust collection box for extracting dust-laden air from a work area of the machine tool, wherein the dust can be filtered out of the dust-laden air using a filter.
  • a virtual center plane can be placed through a main body of the machine tool and/or the dust collection box, with the virtual center plane dividing the main body into two halves, with an inlet of the dust collection box for the dust-laden air predominantly on one side and the filter of the dust collection box predominantly on the other Side of the middle plane is arranged.
  • the invention relates to a dust collection box for a machine tool, wherein the inlet and the filter of the dust collection box are on different sides, i.e. in different halves of the rod collection box.
  • dust collection boxes are known which can be connected to the machine tool in order to extract dust-laden air from a working area of the machine tool.
  • Machine tools can be connected to tools that can be used to carry out work.
  • the hammer drill can be connected to an elongated tool which can be driven by the device into a rotating and/or a striking movement.
  • so-called "onboard" dust collection boxes for machine tools there are mainly two different types of dust collection boxes known: On the one hand, dust collection boxes are known in which the suction channel between the work area and the dust collection box is guided along the tool on one side of the tool of the machine tool.
  • dust collection boxes are known in which the suction channel is guided in or near a plane, the plane containing a working axis and a grip axis of the machine tool. This level is therefore preferably also referred to as the “working plane” of the machine tool.
  • the working axis corresponds to the axis in which the tool of the machine tool lies, the handle axis containing the main handle of the machine tool.
  • the dust collection boxes with the lateral guidance of the suction channel often have good suction performance, but are often very large and unwieldy, so that the machine tool, when connected to such a dust collection box, also becomes very large and unwieldy. This can make handling the machine tool more difficult and make working with the machine tool less comfortable and laborious.
  • the filter for filtering out the dust from the dust-laden air is often located on a front or rear wall of the dust collection box. This can disadvantageously cause dust to collect on the filter when the machine tool is being used on a surface such as a floor or ceiling, i.e. overhead. In this way, the filter can quickly become clogged, so that, for example, only a small number of drill holes can be created with the machine tool before the filter has to be replaced or cleaned.
  • the object on which the present invention is based is to overcome the shortcomings and disadvantages of the prior art described above and to provide a machine tool that combines the advantages of the known designs.
  • the dust collection box to be provided should be particularly compact and handy in order to be able to provide a handy and comfortable machine tool.
  • Experts would welcome it if a cost-effective and easy-to-replace filter could be provided for the dust collection box and if the dust collection box could be designed to be particularly tight in order to optimally utilize the existing suction power and not have any leaks.
  • a machine tool which can be connected to an elongated tool which extends forward in a spatial direction.
  • the machine tool is set up to drive the tool to a rotating and/or striking movement.
  • the machine tool comprises a dust collection box and can be releasably connected to it, the dust collection box being designed to extract dust-laden air from a working area of the machine tool and to filter out the dust from the dust-laden air by means of a filter, so that the dust in an interior of the dust collection box up to can be collected during emptying.
  • a virtual center plane can be placed through a main body of the machine tool and/or the dust collection box, wherein the virtual center plane is set up to divide the main body into a first side and a second side in a sectional view looking from a front spatial direction.
  • An inlet of the dust collection box for the dust-laden air is arranged predominantly on one side of the central plane, while the filter of the dust collection box is predominantly arranged on the other side of the central plane.
  • This Advantage of the machine tool can be achieved in particular in all three main applications of the machine tool (working on the floor, on the wall and overhead on the ceiling), because in none of the three main applications is the filter covered by dust, so that it quickly becomes clogged or blocked becomes. Due to the arrangement and design of the dust collection box, the dust advantageously falls next to the filter in the main applications, so that the invention avoids “flooding” or “sugaring” of the filter.
  • the proposed arrangement of the dust collection box on the machine tool is referred to as “asymmetrical” within the meaning of the invention.
  • the dust collection box of the proposed machine tool is preferably referred to as an “asymmetric dust collection box” in the sense of the invention, the asymmetrical arrangement of the components of the dust collection box being characterized in that the inlet of the dust collection box is predominantly on one side of the main body of the machine tool and / or the dust collection box is arranged, while the filter of the dust collection box is arranged predominantly on the other or opposite side of the main body of the machine tool and / or the dust collection box.
  • the dust-laden air can be guided from the work area through a suction channel to the inlet of the dust collection box, with the virtual central plane running through the suction channel.
  • the suction channel is located in the middle of the machine tool or in the dust collection box, which is expressed by the fact that the virtual center plane cuts the suction channel and mentally divides it into two essentially symmetrical halves.
  • the dust collection box has a second seal, the second seal being designed to direct the cleaned air from the filter to a suction unit of the dust collection box.
  • the second seal is preferably present in an upper region of the dust collection box.
  • the machine tool has a first seal for conducting the dust-laden air into the dust collection box and a second seal for conducting the cleaned air from the filter to a suction unit of the dust collection box, the first seal and the second seal being in are oriented in essentially the same spatial direction.
  • this preferably means that the first and second seals are essentially parallel and point essentially in the same spatial direction.
  • first seal and the second seal are arranged at the same height within the machine tool or within the dust collection box. In this way, the seals can be manufactured particularly cost-effectively.
  • seals that are arranged in the manner described are particularly tight and have a good sealing effect with little effort at the same time. This means that the existing suction power of the dust collection box's suction unit can be used particularly well and unwanted leaks can be effectively prevented.
  • an air guide element can be made in one piece in this way, whereby the already good sealing effect of the seals of the dust collection box can be further improved. It is therefore preferred in the sense of the invention that the dust collection box has an air-guiding element, the air-guiding element being formed in one piece.
  • the air guide element can be designed, for example, as an air guide plate. However, in the context of the invention, it can also be preferred that the air guiding element comprises plastic or is made of plastic.

  • two seals and particularly preferably all three seals are integrated in a filter frame of the dust collection box.
  • Such a filter can preferably be referred to as a lamellar filter within the meaning of the invention.
  • the proposed arrangement of the filter in the dust collection box can advantageously ensure that the direct path or the shortest connection from the inlet of the dust collection box in the direction of the filter runs essentially parallel to a normal direction to the slats of the filter. This advantageously means that the initially dust-laden air flow essentially only has direct contact with the outer lamella of the filter and can therefore only contaminate and clog it.
  • the filter is designed as a lamella filter, with the direct path and/or the shortest connection through the dust collection box striking the lamellae of the lamella filter essentially perpendicularly.
  • the filter by designing the filter as a lamella filter and by guiding the air flow through the dust collection box, a filter with fewer lamellas can be used than in conventional dust boxes, as are known from the prior art.
  • the filter can be designed to be particularly compact and space-saving and the dust collection box can be kept compact overall.
