Definitions

  • the present invention relates to a portable wet vacuum cleaner, wherein the wet vacuum cleaner comprises a container for collecting a liquid-dirt mixture.
  • the wet vacuum cleaner is particularly characterized by an inclined sealing plane as the upper end of a collecting container of the wet vacuum cleaner, wherein the inclined sealing plane comprises a filter unit.
  • the dust that is created on a construction site is often harmful to health and should not be inhaled by people.
  • Primary dust is created during various applications, such as drilling, chiseling or grinding surfaces. This dust spreads in the air and can easily be inhaled by people nearby. The dust can also collect on the floor or other surfaces and thus becomes secondary dust. With regard to this secondary dust, there is a risk that the dust will be stirred up again during further work steps and thus enter the respiratory tract of workers or passers-by.
  • a dust extractor is usually used, which uses suitable systems or attachments to collect and/or extract the dust directly at the point of origin. This prevents the dust from entering the ambient air and being inhaled by workers or passers-by.
  • a dust extractor or vacuum cleaner is also often used to extract secondary dust in order to specifically suck up and dispose of the dust from the floor.
  • wet vacuum cleaner systems known from the state of the art are usually based on the wet vacuum cleaners having a single defined position when they are operated. For example, mobile wet vacuum cleaners on wheels can be moved across the floor, always standing upright and, in particular, not tipping over. During operation, an imaginary central axis running through the middle of the wet vacuum cleaner is usually essentially perpendicular to the subsurface or the floor to be cleaned, over which the wet vacuum cleaner can be moved. This defined operating position of the wet vacuum cleaner in the room can ensure that individual components of the wet vacuum cleaner do not come into contact with the mud or the liquid-dirt mixture. In particular, it should be avoided that the filter, the motor, the filter cleaning unit or the vacuum cleaner turbine become soaked with liquid. Such wetting of the components mentioned can lead to damage and a malfunction of the wet vacuum cleaner or its individual components.
  • the vulnerable components of a fictitious portable wet vacuum cleaner could come into contact with mud and liquid in particular if the user leans forward with such a vacuum cleaner on his back, for example to pick up an object from the floor. This tilting would move the mud in the collecting container inside the wet vacuum cleaner so that it could reach the area of the components that are to be protected from the mud and the liquid liquid-dirt mixture.
  • the EP 0 827 709 A2 a device for steam cleaning surfaces, which prevents the annoying dripping of condensate onto a surface that has just been cleaned and which comprises a steam discharge device associated with a steam source.
  • a cleaning fluid is contained or stored in the device, and it can be a challenge to protect the suction motor or the suction turbine of the device from this fluid, especially if the device is tilted.
  • the object underlying the present invention is therefore to provide a wet vacuum cleaner that does not have the deficiencies and disadvantages of the prior art and can be used as a portable, mobile system.
  • a wet vacuum cleaner is to be developed that allows the user to vacuum up liquids and sludge without cables and in a highly mobile manner.
  • the object of the invention is to develop a backpack dust extractor that can also process and/or absorb liquids.
  • the wet vacuum cleaner to be provided should be able to be used in various, frequently occurring work situations that involve tilting the vacuum cleaner in different directions, without potentially vulnerable components such as the turbine, motor, filter cleaning module and/or filter being impaired by the liquids contained in the vacuumed sludge.
  • the wet vacuum cleaner can in particular be carried on the back of a user.
  • the wet vacuum cleaner can comprise the corresponding fastening means or straps to enable the user to carry the wet vacuum cleaner pleasantly and comfortably.
  • the wet vacuum cleaner has a collecting container, the back of which faces the back of the user when the wet vacuum cleaner is carried by the user on his back.
  • the front of the collecting container is preferably substantially parallel to the back of the collecting container, while a bottom or a bottom surface of the collecting container is formed substantially perpendicular to the back and/or the front of the collecting container.
  • the collecting container is closed in an upper region by an upper closure, wherein this upper closure is preferably arranged opposite the bottom or bottom side of the collecting container.
  • the upper closure is also referred to as the top of the collecting container.
  • the top of the collecting container comprises an inclined sealing plane, wherein the inclined sealing plane comprises a filter unit of the wet vacuum cleaner.
  • the container for collecting a liquid-dirt mixture is preferably also referred to as a collecting container and the arrangement of components in the backpack vacuum cleaner is referred to as a component arrangement.
  • a particular advantage of the invention is that the proposed backpack vacuum cleaner can be used regardless of position.
  • the term "independent of position” preferably means that the vacuum cleaner can be used in particular in frequently occurring work situations that can involve the wet vacuum cleaner tipping over. These frequently occurring work situations preferably define permitted tipping states, whereby the inclination of the sealing plane within the collecting container of the backpack vacuum cleaner can advantageously ensure that the proposed wet vacuum cleaner can be used in these permitted tipping states without the vacuum cleaner components, such as the motor, turbine, filter cleaning unit and/or filter, coming into contact with liquid or mud.
  • permitted tipping conditions exist in the following situations: if a) the wet vacuum cleaner is tilted forwards between 0 and 90 degrees, b) the wet vacuum cleaner is tilted to the side by less than 30 degrees, preferably less than 20 degrees, and/or c) the wet vacuum cleaner is tilted backwards by less than 30 degrees. Accordingly, prohibited tipping conditions can exist in particular if a) the wet vacuum cleaner is tilted forwards by more than 90 degrees, b) the wet vacuum cleaner is tilted to the side by more than 20 degrees, preferably more than 30 degrees, and/or c) the wet vacuum cleaner is tilted backwards by more than 30 degrees.
  • the angles mentioned are preferably viewed from a substantially vertical axis, this substantially vertical axis representing an imaginary or virtual axis which preferably runs substantially parallel to the user's spine.
  • the spatial direction "forward” in the sense of the invention preferably refers to the user “bending forwards", in which the user's upper body bends forwards, i.e. in the spatial direction facing away from the user's back or in the direction of the user's stomach.
  • a distance between the user's face and stomach is shortened.
  • the spatial direction “backward” preferably corresponds to the user “bending backwards", wherein when the user "bends backwards", a distance between the front of the wet vacuum cleaner and the floor is preferably reduced.
  • the spatial directions "forward” and “backward” do not correspond to the side surface designations of the collecting container or the wet vacuum cleaner.
  • the side of the wet vacuum cleaner or the collection container facing the user or his back is preferably referred to as the "back” of the wet vacuum cleaner or the collection container, while the opposite side of the wet vacuum cleaner or the collection container is referred to as the "front” of the wet vacuum cleaner or the collection container.
  • the filter of the wet vacuum cleaner is arranged on a side facing away from the "forward tilting direction".
  • the filter is arranged in the area of the top of the collecting container, specifically in the direction of the front of the collecting container, which is preferably facing away from the user's back when the user is carrying the backpack vacuum cleaner on his back.
  • This preferred arrangement of the filter within the vacuum cleaner advantageously ensures that the filter is not soaked with liquid or comes into contact with it even if the wet vacuum cleaner is tilted, in particular in the spatial direction forwards, as long as the tilting takes place within the permitted angular ranges.
  • the wet vacuum cleaner comprises a gyro sensor that is designed to detect a tipping of the wet vacuum cleaner.
  • the detection of the unauthorized tipping states is preferably carried out with the aid of the above-mentioned angle values and using the gyro sensor.
  • an unauthorized state is detected when a user who is carrying the backpack vacuum cleaner on his back bends forward by more than 90 degrees.
  • the wet vacuum cleaner in conjunction with the gyro sensor is capable of switching off the wet vacuum cleaner when unauthorized Tilting conditions can be detected.
  • the gyro sensor would detect the presence of an unauthorized tilting condition if the wearer of the wet vacuum cleaner leans forward by more than 90 degrees.
  • the wet vacuum cleaner would then be switched off automatically - for example using a control device that is connected to the gyro sensor and the wet vacuum cleaner or can exchange information and/or control errors with them - in order to prevent the mud or moisture in the vacuum cleaner's collecting container from reaching the area of the filter unit or the sealing plane of the collecting container or the wet vacuum cleaner.
  • the wet vacuum cleaner preferably comprises a gyro sensor that is set up to switch off the wet vacuum cleaner from a tilt angle of 90° "forwards", 20-30° to the left or right and up to 30° "backwards” and thus prevent water from being sucked through the filter into the turbine.
  • the gyro sensor can communicate with a control unit of the wet vacuum cleaner in such a way that the suction of the liquid-dirt mixture is prevented if an unauthorized tipping state is present. This can be achieved, for example, by switching off the motor and/or the turbine of the wet vacuum cleaner if the gyro sensor detects an unauthorized tipping state.
  • the wet vacuum cleaner is operated in particular in the permitted tipping states, whereby the permitted tipping states correspond in particular to the frequently occurring work situations that can be accompanied by a tipping of the wet vacuum cleaner in the above-mentioned "permitted" angle ranges.
  • the upper end of the collecting container which comprises the inclined sealing plane and the filter unit, can preferably also be referred to as the top of the collecting container.
  • the top of the collecting container can preferably have two different sections or be formed by these different sections.
  • the top of the collecting container comprises a substantially horizontal section, wherein the substantially horizontal section is designed to connect a rear side of the collecting container and the inclined sealing plane.
  • the substantially horizontal section of the top of the collecting container is located between the inclined sealing plane and the rear side of the collecting container.
  • the collecting container comprises an upper horizontal edge so that the largest possible tilt angle of the wet vacuum cleaner can be achieved without the collected water flooding the sealing surface and, for example, the components contained therein, such as the filter unit.
  • the sealing plane preferably also protects the components arranged above the sealing plane, such as the turbine, filter cleaning unit and/or motor, due to its position. Due to the position of the sealing plane within the wet vacuum cleaner or of the backpack vacuum cleaner, a sufficiently large space is provided in the upper area for the optimized arrangement of the components to be protected from the dirty water, while in the lower area of the vacuum cleaner there is sufficiently large space to accommodate the liquid-dirt mixture.
  • the area above the sealing plane is preferably referred to as the sealing space in the sense of the invention.
  • the inclined arrangement of the sealing plane which includes the filter unit, enables an optimal division of space within the proposed wet vacuum cleaner.
  • the components of the vacuum cleaner that are to be protected from the sludge such as the motor, turbine, filter cleaning unit and/or filter unit, can be optimally protected from coming into contact with the liquid.
  • the preferred arrangement of the components in the proposed wet vacuum cleaner therefore protects them particularly effectively against unwanted soaking, so that the proposed invention surprisingly makes it possible to provide a portable backpack wet vacuum cleaner that can also be used in frequently occurring work situations that involve the wet vacuum cleaner tipping over.
  • the invention therefore represents a departure from the state of the art, as experts had previously assumed that wet vacuum cleaners could not be provided as backpack vacuum cleaners.
  • a filter cleaning module of the wet vacuum cleaner is arranged centrally above the filter unit.
  • the wet vacuum cleaner preferably comprises a filter cleaning module which is arranged in particular substantially centrally above the filter unit. Since the filter unit is preferably arranged in the inclined sealing plane of the collecting container, it is preferred in the sense of the invention that the filter cleaning unit is arranged in the extension of an imaginary central axis which preferably runs centrally through the filter unit.
  • the arrangement of the filter cleaning module is also shown in the figures. It is preferred in the sense of the invention that the filter cleaning module is also referred to as the APFC module of the wet vacuum cleaner.

  • the upper area of the wet vacuum cleaner forms a sealed area or a sealing area, with the turbine and the energy supply unit being arranged in this sealing area.
  • the preferred arrangement of the energy supply unit and the turbine next to each other and in spatial proximity to the rear of the collecting container, in particular in the sealing area of the wet vacuum cleaner in particular achieves an optimal weight distribution within the wet vacuum cleaner, which is particularly advantageous when the backpack vacuum cleaner is carried on the back by a user.
  • the "heavy" components, such as batteries and turbine are close to the user thanks to this preferred arrangement, so that the weight of the vacuum cleaner is not unnecessarily increased by a distant arrangement of these components.
