Definitions

  • the present invention relates to a device for receiving a suction hose which connects a nozzle of a vacuum cleaner to a central unit of the vacuum cleaner.
  • the device is characterized in that it has at least one holding device which can be arranged on the central unit of the vacuum cleaning device, wherein the suction hose can be inserted into the at least one holding device so that the hose can be securely and stably accommodated.
  • the invention advantageously makes it possible for a user of the vacuum cleaning device to be able to adapt the length of the suction hose as required to the task currently to be performed.
  • the part of the suction hose that is not used is particularly securely and stably stored in the device or in cavities of the device that can be formed between the at least one holding device and a rear part.
  • the invention relates to a vacuum device with a receiving device.
  • the dust produced on a construction site is often harmful to health and should not be inhaled by people.
  • Primary dust is generated in various applications such as drilling, chiselling 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 become secondary dust. With regard to this secondary dust, there is a risk that it will be whirled up again during further work steps and thus get into the respiratory tract of workers or passers-by.
  • a dust extractor In order to avoid the spread of primary dust, a dust extractor is usually used which, through suitable systems or add-on parts, is able to collect and / or suck off the dust directly at its point of origin. This prevents the dust from entering the ambient air and being inhaled by workers or passers-by.
  • a dust extractor or a vacuum cleaner To the Sucking off the secondary dust is mostly a dust extractor or a vacuum cleaner used to specifically suck up and dispose of the dust from the floor.
  • the vacuum cleaner is referred to as a back vacuum cleaner, back vacuum cleaner or back vacuum cleaner device within the meaning of the invention.
  • Modern vacuum cleaning devices can be used flexibly in different areas of application, for example both as a load-bearing back vacuum cleaner that is transported on the back of a user and as a floor-mounted vacuum cleaner that can move across the floor with rollers or wheels, for example.
  • the optimal hose length for this application can be, for example, 3 m or more, so that, for example, bores near the ceiling or in hard-to-reach places can be extracted directly.
  • an optimal hose length of significantly less than 2 m can be advantageous, since otherwise the excess hose length can drag on the floor and / or pose a tripping hazard.
  • the object of the present invention is to provide a cost-effective, robust system for accommodating the suction hose which allows the user to be able to flexibly store the excess length of the hose. From the point of view of experts, it would be particularly desirable if the user could still vary the hose length when the teat is already on the user's back.
  • hoses are known in the prior art which can contract by themselves.
  • these hoses are unsuitable for vacuum cleaners that are equipped with automatic filter cleaning.
  • Devices for performing an automatic filter cleaning often have an air leakage valve.
  • a pressure surge is usually generated which, in connection with the air leakage valve, leads to this could that a suction hose as described above can suddenly contract and expand again.
  • This movement would possibly continue to the central unit of the vacuum cleaner, so that this jerky movement can be transferred to a user who is currently working with the vacuum cleaner.
  • This can have a disadvantageous effect on the operability of the teat, since jerky forces can occur on the teat, which can for example mean that the user can no longer guide the teat in a targeted manner.
  • the suction cup is often connected to a machine tool, such as a drill or a grinding machine. The contraction of the hose can also impair the operability of the machine tool.
  • a further object on which the present invention is based is thus to provide an accommodation option for a suction hose of a vacuum cleaner device, which is designed to be particularly simple and inexpensive.
  • the device to be provided should be designed to be so robust, in particular against external influences such as moisture or dust, that it can also be used without problems in dust-intensive locations such as construction sites.
  • the device should be able to be used in conjunction with vacuum cleaners that can be used both as floor-mounted vacuum cleaners and as back vacuum cleaners, with the solution to be provided in particular being able to be used in conjunction with filter cleaning on the vacuum cleaner.
  • the object is achieved by a device for receiving a suction hose which connects a nozzle of a vacuum cleaner to a central unit of the vacuum cleaner.
  • the device is characterized in that it has at least one holding device which can be attached to the central unit of the vacuum cleaning device, the suction hose being insertable into the at least one holding device so that the hose can be securely and stably accommodated. It is preferred in the context of the invention that the suction hose is placed in loops in the at least one holding device, so that a length of the suction hose can be determined by a number of loops.
  • a longer hose length is available for working with the vacuum cleaner if the hose is looped around the holding device with a few loops, meanwhile, a shorter hose length is available for working with the vacuum cleaner if the hose is looped around the holding device with many loops.
  • the vacuum cleaner has a central unit, which preferably has a motor, a turbine and a dust collector.
  • the turbine can be used to generate a vacuum with which dust can be sucked into the interior of the vacuum cleaner.
  • a dust collection container can be arranged in which the sucked-in dust can be collected.
  • a dust (collection) bag can be inserted into the dust collector, which can be replaced when the bag is full.
  • the turbine for generating the negative pressure can be driven by a motor, which is preferably an electric motor.
  • the central unit can also have a control device, operating elements or communication means. The control device is preferably set up to control the vacuum device.
  • the operating elements can be used by a user to make settings on the vacuum cleaner, to set a suction power or to switch the vacuum cleaner on or off. Any means of communication can be used so that the vacuum cleaner can communicate with other devices, such as a tool device, an accessory or other mobile devices, such as a smartphone.
  • the central unit can be connected to a nozzle for sucking in the dust via a suction hose.
  • the nozzle can preferably be a Bo dendüse, with which dust lying on the floor in particular can be sucked up.
  • the nozzle can also be designed in any other conceivable way in order to take up dust.
  • the central unit of the vacuum cleaner can also include a filter that protects the turbine from dirt and dust. By absorbing these impurities, the filter can become clogged, with a solid filter cake often forming on the filter.
  • the filter can preferably be cleaned mechanically by means of a filter cleaning process so that the filter is then available again with its full filter performance.
  • the proposed invention enables a commercially available suction hose to be used as the suction hose which does not have any special features that enable it in particular to contract automatically. Such contracting hoses, as they are known from the prior art, often cannot be used in connection with suction cups which are designed to carry out an automatic filter cleaning. Since a commercially available suction hose can be used in connection with the invention, the proposed arrangement can acquisition device can advantageously also be used in conjunction with a vacuum cleaner with filter cleaning.
  • the device does not include any moving parts.
  • the device is particularly ro bust against external influences such as dust and / or moisture.
  • a vacuum cleaning device with a proposed receiving device does not have any gaps that can arise, for example, as a result of the movement of components. Such inter mediate spaces often serve as gateways for dust and / or moisture.
  • the proposed vacuum cleaner with the proposed receiving device which preferably does without moving parts, is particularly well protected against these external influences and is therefore particularly suitable for use on the construction site and especially outdoors.
  • the formulation that “the device does not include any moving parts” preferably means in the context of the invention that the device in particular does not include any displaceable, rotating or relocatable components.
  • the holding devices at least partially comprise elastic material in which they can be designed as a clip, for example.
  • the suction hose can be inserted and / or clipped into such a clip, for example, so that it can be fastened in a stable and secure manner. This in particular prevents the hose from moving freely and disturbing, hindering or even endangering the user when using the vacuum cleaner.
  • the at least one holding device comprises metal and / or plastic.
  • the holding devices can be made from bent sheet metal parts or plastic parts which have an optimal elasticity for use as an elastic holding device.
  • the elasticity can be adjusted via a suitable choice of thickness and / or material for the bent sheet metal or plastic parts.
  • the at least one holding device has a corrugated profile. This is particularly advantageous in order to avoid squeezing the suction hose.
  • the phrase “corrugated profile” in the context of the invention preferably means that the holding device can comprise, for example, an elastic piece of plastic or metal which has hills and valleys or elevations and depressions (see, for example, FIG. 1).
  • the terms “deepening” and “increasing” are not unclear for the expert Terms because the person skilled in the art defines the terms in the context of the present invention via a respective distance from a rear part of the receiving device.
  • a recess in the holding device or in the corrugated profile is particularly characterized in the sense of the invention that the recess is at a greater distance from a rear part of the carrying system than an elevation of the holding device or the corrugated profile. This applies in particular to a deepest point of depression and a highest point of elevation.
  • the depressions can, for example, be designed to each receive a loop of the suction hose, wherein a distance between the depression of the holding device and a rear part of the device can correspond to a diameter of the suction hose.
  • the term “correspond” in the context of the invention preferably means that the distance between the recess of the holding device and the rear part of the device can be matched to the suction hose used or its diameter.
  • the distance can be selected so that the suction hose can be safely and stably received in the cavity that is formed between the recess of the holding device and the rear part of the device and easily jammed so that it is not manned by normal vibrations and loads falls out of the cavity.
