Definitions
- the present invention relates to a disposal bag for a vacuum cleaning device, the disposal bag having a pressure compensation matrix.
- the pressure equalization matrix has openings which are set up to effect a pressure equalization between a first area and a second area of a collecting container of the vacuum cleaner device. This can prevent the disposal bag from being sucked in by the vacuum-generating turbine, which can restrict its functionality.
- the vacuum cleaner can preferably be a construction site vacuum cleaner, the collecting container of the vacuum cleaner being set up for receiving the disposal bag and the dust sucked in by the vacuum cleaner being collected and caught in the disposal bag.
- the invention relates to a method for producing a disposal bag according to the invention, as well as its use in a vacuum cleaner device.
- vacuum cleaner bags as disposal bags for the dust.
- these disposal bags are placed in an interior space of the vacuum cleaner and filled with dust while the vacuum cleaner is in operation.
- the disposal bag When the disposal bag is full, it must be replaced with a fresh, ie empty, bag. To do this, the full bag is removed from the vacuum cleaner and disposed of appropriately.
- Areas of application for vacuum cleaners are the household or places where there is a particularly large amount of dust, some of which is hazardous to health, such as construction sites. In the field of construction sites, one often speaks of construction (site) vacuum cleaners. Alternatively, the term "dust extractor" can also be used.
- Dust can arise, for example, when working with hand-held machine tools such as drills, grinders or saws. In the context of the invention, it is preferably also referred to as a suction medium.
- a turbine which is driven by a motor, is used to generate a negative pressure with which the suction medium is sucked into the interior of the vacuum cleaner.
- Disposal bags are used in construction vacuum cleaners to collect the suction medium in a removable and closable container and thus to protect the environment and users from increased dust exposure.
- the disposal bag is preferably removable, ie designed to be exchangeable. Construction vacuum cleaners often include a collecting container to hold the disposal bag in which the dust is collected.
- many construction vacuum cleaners include what is known as a suction head, which closes the collecting container.
- the disposal bags are placed in the collecting container and over its edge, so that the bag is fixed and hermetically sealed after the suction head is attached.
- suction mode two different pressure areas are created inside the collecting container.
- a first area which is preferably present between a container wall and the disposal bag, there is essentially atmospheric or normal pressure.
- the negative pressure generated by the turbine prevails inside the disposal bag. If the disposal bag is placed in the collecting container in such a way that it has sufficient freedom of movement, the bag can move inside the collecting container. It can then - undesirably - happen that the flexible bag moves in the direction of the turbine of the vacuum cleaner and / or is sucked in by the turbine. This can negatively influence or impair the suction process.
- Another concern of the present invention is therefore to provide a disposal bag for a vacuum cleaner, with which dust leakage from the disposal bag can be particularly effectively avoided.
- a particularly cost-effective and dust-free disposal bag for a vacuum cleaner device is to be provided, the vacuum cleaner device in particular as a construction vacuum cleaner can be used.
- the invention is intended to prevent the disposal bag from moving in the direction of the vacuum-generating turbine and hindering it in its work.
- a disposal bag for a vacuum cleaner in particular a construction site vacuum cleaner, is provided, the vacuum cleaner having a collecting container for receiving the disposal bag.
- the disposal bag is characterized in that it has a pressure compensation matrix, the pressure compensation matrix having openings which are set up to effect pressure compensation between a first area and a second area of the collecting container.
- the pressure compensation matrix with its openings represents a particularly effective way of achieving pressure compensation between the negative pressure generated by the vacuum cleaner's turbine (“second area”) and in the disposal bag, and the Normal or atmospheric pressure between the disposal bag and the inner outer wall of the collecting container of the vacuum cleaner (“first area”).
- the spatial areas with different pressure conditions are preferably referred to as first and second areas in the context of the invention.
- the term “fluidic connection” preferably means that an exchange of fluid and / or material between the first and the second area can take place.
- the fluid to be exchanged is preferably a gas or a gas mixture, in particular the gas mixture occurring in the atmosphere, which essentially comprises oxygen (02) and nitrogen (N2), as well as small amounts of other gases and gas mixtures (“air”) .
- the pressure equalization is symbolized in FIG. 2 by the dashed arrow.
- the first area is preferably formed between a wall of the collecting container and the disposal bag, while the second area corresponds to the interior of the disposal bag.
- different pressure areas are formed in the lower area of the vacuum suction device in the suction mode, which in the sense of the Invention are preferably referred to as the first and second area.
- the suction device when the suction device is in operation, there is an atmospheric pressure in the first area and a negative pressure in the second area.
- the negative pressure in the second area is the cause of the unwanted suction of the disposal bag by the pressurized turbine.
- the openings in the pressure equalization matrix allow pressure equalization between the two different pressure areas so that the disposal bag is no longer sucked in by the turbine.
- atmospheric pressure is not an unclear term for the person skilled in the art, because the person skilled in the art knows that the term denotes the air pressure usually present in the atmosphere. This is the hydrostatic pressure of the air, which according to the norm is 1013.25 hPa. The person skilled in the art thus knows that the term “atmospheric pressure” denotes an air pressure value in this range.
- negative pressure preferably denotes a value that is less than atmospheric pressure.
- the pressure difference that forms in the collecting container when the vacuum cleaner is in operation is preferably the difference between the negative pressure generated by the turbine for sucking in the dust medium and the currently prevailing atmospheric pressure.
- the negative pressure is preferably in the second area inside the disposal bag and the atmospheric pressure in the first region between an inner wall of the collecting container and an outer wall of the disposal bag.
- the equalization of this pressure difference is preferably referred to as pressure equalization in the context of the invention.
- pressure equalization within the collecting container of the vacuum cleaner or between the interior of the supply bag and the surrounding interior of the collecting container can advantageously be made possible, so that the bag is effectively prevented from being sucked into the turbine.
- the pressure equalization is preferably made possible by the fact that gas and / or material can be exchanged between the first area and the second area within the collecting container of the vacuum cleaning device. This exchange preferably takes place through the openings which form the pressure compensation matrix. Since the production of the proposed disposal bag with pressure compensation matrix can be carried out more cost-effectively than the production of the conventional special disposal bags known from the prior art, the consumption costs of vacuum cleaning can be reduced considerably by the invention.
- the matrix perforation which is present in the disposal bags according to the invention and which ensures the necessary pressure equalization of the two bag areas, means that the use of the cost-intensive special bags can be dispensed with.
- a significant advantage of the preferably punched-in pressure compensation matrix is that less costly disposal bags without filter fleece can be used in the vacuum device in order to prevent an undesired escape of dust from the disposal bag.
- the term “matrix” preferably means that the openings which form the pressure compensation matrix are punched into the disposal bag according to a predetermined pattern.
- the openings can be arranged, for example, in the form of a table with columns and rows.
- the shape or configuration of the pressure compensation matrix can resemble a grid.
- the pressure compensation matrix is arranged essentially circumferentially in an upper region of the disposal bag.
- this preferably means that the bag, in the inserted state, has a completely or partially circumferential pressure compensation matrix with regularly arranged pressure compensation openings in the area of the upper end of the collecting container.
- the fluid and / or material exchange between the first and the second area of the collecting container of the vacuum cleaner which advantageously leads to the pressure equalization, can take place particularly uniformly and homogeneously. In particular, this effectively prevents undesirable air turbulence, which can be associated with a likewise undesirable dust leakage from the disposal bag.
- the spatial direction “above” or “from above” is preferably determined in the sense of the invention by the arrangement of the suction head, while the spatial direction “below” or “from below” is determined by the ground or, for example, by the arrangement of wheels of the vacuum cleaner. Accordingly, the suction head forms the top of the vacuum cleaner, while the outer wall of the collecting container facing the ground forms the bottom of the vacuum cleaner.
- the phrase "upper area of the disposal bag” is shown in the inserted state of the bag in Fig.
- the upper area of the disposal bag is preferably in the area of the upper end. ses of the collecting container (see Fig. 2).
- the arrangement or position of the pressure compensation matrix preferably defines the upper area of the disposal bag.
- the pressure compensation matrix preferably runs like a band around the upper area of the proposed disposal bag, whereby this pressure compensation band can, for example, have a width in a range from 1 to 15 cm, preferably in a range from 2 to 10 cm, particularly preferably in a range of 3 to 7 cm and most preferably 4 cm.
- a possible embodiment of the circumferential pressure compensation matrix designed as a pressure compensation band is shown, for example, in FIG. 3.
- the pressure compensation matrix can comprise individual pressure compensation matrix areas which are arranged in an upper area of the disposal bag.
- the pressure compensation matrix areas are preferably spaced from one another and form, for example, small grids or structures of openings arranged in a table.
- 2 to 10, preferably 4 to 8, particularly preferably 5, 6 or 7 such pressure compensation matrix areas can be arranged in the upper area of the disposal bag.
- the pressure compensation matrix areas can be similar to the pressure compensation band described above, but as a modification they do not include a continuous or circumferential pattern of openings, but rather individual, spaced apart individual areas with openings that are used as pressure compensation matrix areas in the context of the invention be drawn.
- the openings can be arranged in the form of columns and rows within these pressure compensation matrix areas.
- the pressure compensation matrix areas comprise columns and rows in which the openings are arranged.
- this preferably means that the openings can be arranged in longitudinal and transverse rows that run essentially parallel and / or perpendicular to one another.
- notch or“ table ” knows how to arrange openings similar to a grid or in the form of columns and rows, such as in a table, to one another.
- the term “essentially perpendicular or parallel” is not an unclear term for the person skilled in the art, since the person skilled in the art knows how to make or punch openings in a plastic material so that the openings are arranged in longitudinal and transverse rows "Substantially perpendicular or parallel” are arranged to each other.
- the term “essentially” preferably means that the longitudinal and transverse rows of the openings in the pressure compensation matrix should be arranged perpendicular to or parallel to one another within the scope of manufacturing accuracy.
- the term “column” preferably denotes a row of openings running from top to bottom within the matrix.
- the term “line” preferably denotes a row of openings running from right to left or from left to right within the matrix.
- a column within the pressure compensation matrix runs from an upper edge of the grid in the direction of a lower edge, while the rows within the pressure compensation matrix connect the side edges to one another.
- the columns and / or rows are arranged with respect to one another in such a way that the openings are essentially arranged next to one another.
- this preferably means that the openings of adjacent columns or rows are arranged essentially next to one another.
- the openings in this embodiment of the invention have essentially the same or similar distances from one another and openings in adjacent columns or rows are essentially at the same or a similar height within the pressure compensation matrix or the pressure compensation matrix areas.
- Exemplary embodiments of pressure compensation matrix areas in which the openings of adjacent columns and rows are arranged next to one another are shown in FIGS.
- the openings are arranged offset from one another.
- this preferably means that the openings in adjacent columns and rows are not arranged at the same height, but that adjacent columns and / or rows are arranged offset from one another by a preferably fixed distance d.
- the openings in columns or rows adjacent to one another can be set to gaps.
- An exemplary embodiment for columns and rows that are offset from one another is shown in FIG.
- the pressure compensation matrix areas have an essentially rectangular basic shape, with individual side lengths of the essentially rectangular basic shape being in the range from 1 to 15 cm, preferably in a range from 2 to 10 cm, particularly preferred in a range of 3 to 7 cm and most preferably 4 cm.
- an essentially square pressure compensation matrix area is shown, the arrows below and to the left to the side of the pattern representing the side lengths of this essentially square pressure compensation matrix area.
- These side edges can, for example, have a length of 4 cm.
- Pressure compensation matrix areas with side lengths in a range of 4 cm have proven to be shown particularly well suited for optimal pressure equalization and minimal back-dusting.
- the openings that form the pressure compensation matrix are punched into the disposal bag.
- the individual openings can be made individually or in groups in the starting material for the disposal bag.
- the openings can be punched into the starting material for the disposal bag in columns or rows. Punching the openings into the disposal bag has the advantage that, surprisingly, there is no waste when creating the openings.
- the openings each have a collar, the collar extending into the second area of the collecting container.
- the collars preferably extend into the interior of the disposal bag. Due to this specific design of the openings or their manufacturing process, no punching waste arises, since the material pressed out of the disposal bag during punching is advantageously used to form the collar. Application tests have shown that the design of the openings with such a collar enables an efficient pressure equalization between the first and the second area within the collecting container of the vacuum cleaning device.
- the collar-shaped design of the openings and the punching of the openings in the starting material for the disposal bag are preferably linked in the sense of the invention in such a way that, in particular, the introduction of the openings by a punching process leads to or enables the collar-shaped design of the openings.
- the openings can preferably also be referred to as holes or pinholes.
- the openings of the pressure compensation matrix have an essentially circular base area, the essentially circular base areas having a diameter in a range from 0.1 to 10 mm, preferably in a range from 0.3 to 5 mm and particularly preferably in a range from 0.4 to 2.0 mm and most preferably in a range from 0.5 to 1.5 mm. Diameters of the openings of less than 2 mm are very particularly preferred. This advantageously makes it possible lent that the disposal bags to be provided with the invention can be classified in class M or that the bags to be provided can be used in class M suction devices. For the purposes of the invention, it is particularly preferred that the proposed bags can be classified in classes L or M of DIN standard 60335-2-69.
- the pressure compensation matrix in the disposal bag represents a matrix of holes with very small holes, the diameters of the openings being able to lie in the preferred areas mentioned. Tests have shown that, in particular, the diameter of the openings in a range from 0.5 to 1.5 mm results in particularly good pressure equalization in connection with a minimal escape of the suction medium from the disposal bag.
- the pressure compensation openings of the pressure compensation matrix can have a diameter of 0.5 mm; 0.63 mm; 0.75 mm, 1 mm, 1, 2 mm or 1.46 mm.
- the disposal bag comprises a plastic as the starting material.
- the bag can be made from two foils that are, for example, placed one on top of the other and processed with one another.
- each film forms one side of the disposal bag, for example a front and a back or an upper and a lower side.
- only one of the two foils is preferably pierced in order to produce the openings for the pressure compensation matrix. In this way, it is possible to produce such disposal bags in which the openings each have a collar that extends into the second area of the collecting container or into the interior of the bag.
- the collar is produced by the described perforation on only one side of the bag or one bag film in the direction of the interior of the bag.
- This alignment or configuration of the collars of the openings in the pressure compensation matrix effectively prevents dusting through.
- the openings of the pressure compensation matrix are present in only one of the two layers of the starting material of the disposal bag.
- the formation of a countercurrent which can lead to dusting, can be effectively prevented by the collar shape of the openings.
- the plastic of the starting material of the disposal bag can be, for example, low density polyethylene (LDPE).
- LDPE low density polyethylene
- it can have a thickness of approximately 1 mm exhibit. A thickness of 0.95 mm is particularly preferred.
- the plastic material is transparent. This makes it possible to equip the collecting container of the vacuum cleaner with a viewing window that allows a view of the disposal bag. Through the viewing window and the preferably transparent material of the disposal bag, the user can quickly and easily determine how full the disposal bag is and estimate the remaining usage time before the bag has to be changed.
- a vacuum cleaner device which comprises at least one proposed disposal bag for receiving dust.
- at least one vacuum cleaner bag according to the invention is inserted in the vacuum cleaner, in which a pressure equalization between the interior of the disposal bag ("second area” in which the vacuum generated by the turbine of the vacuum cleaner prevails) and the hollow space between the outside of the disposal bag and the inner walls of the collecting container of the vacuum cleaning device (“first area”, in which atmospheric or normal pressure prevails) is brought about by a pressure compensation matrix formed by small holes.
- the invention relates to a method for producing a disposal bag according to the invention.
- the process comprises the following steps: a. Provision of a starting material for the production of the disposal bag, b. Introducing openings in the starting material, the openings forming a pressure equalization matrix, c. Combining the starting material into a finished disposal bag
- the openings are made in the starting material of the disposal bag by one or more punching processes.
- the introduction can preferably also take place as a perforation by strongly embossing the starting material.
- a section of a circle or an arc of a circle is pressed out of the starting material by means of an embossing process.
- the starting material of the disposal bag is at least partially torn by the embossing or perforation.
- each opening is produced by a single punching process.
- a plurality of openings can be produced with one punching process.
- individual columns and / or columns of the pressure compensation matrix areas can each be produced in one punching process.
- entire pressure compensation matrix areas are generated in one punching process.
- the openings are punched in a first and / or a second layer of the starting material of the disposal bag.
- a use of the disposal bag according to the invention in a vacuum cleaner for collecting dust is also disclosed. Since a particularly effective pressure equalization between the first and the second area of the Sammbenzol age of the vacuum cleaner is achieved through the use of the disposal bag according to the invention.
- the provision of the pressure compensation matrix leads before geous to the fact that the negative pressure inside the disposal bag is reduced so that the proposed disposal bag is no longer sucked in by the vacuum-generating turbine, which can impair the performance of the turbine.
- the collars of the openings which form the pressure compensation matrix advantageously result in only a very small amount of dust leaving the disposal bag in an undesired manner.
- This essential advantage of the invention is achieved in particular in that the collars of the openings of the pressure compensation matrix protrude into the second area, ie the inner area of the disposal bag.
