Definitions
- the invention relates to a vacuum cleaner bag with a bag formed of air-permeable filter material with an inlet opening surrounded by a holding plate for suction air to be filtered vacuum cleaner.
- the invention relates to a method for producing a vacuum cleaner bag, in which means which compress its receiving volume in a dust collection chamber of the vacuum cleaner state when switching off the suction compressed in the form of elastic bands are provided.
- the invention also relates to a vacuum cleaner with a blower and with a dust collection chamber in which a bag formed from air-permeable filter material with an inlet opening surrounded by a holding plate for suction air to be filtered can be inserted.
- vacuum cleaner bags were also adapted to the suction performance in terms of their design.
- a vacuum cleaner bag whose filter material consists of a three-layer fiber composite, between two outer support layers high strength an inner layer of microfiber - is arranged - made of polypropylene.
- the two outer layers consist of a fleece - made of nylon fibers - which are welded together. These outer layers have relatively high strength both in the machine direction and across it.
- the vacuum cleaner bag as such is designed firmer in terms of its nature, in particular to meet the suction.
- the invention thus presents the problem of providing a vacuum cleaner bag or a vacuum cleaner in which, in particular, the suction effect is less affected as the degree of filling of the bag increases.
- the invention also raises the problem of disclosing a simple method for producing such a vacuum cleaner bag.
- the bag acts to reduce the receiving volume with elastic means whose spring force is smaller than the suction force. Due to the interaction of the restoring elasticity force of the bag on the one hand and the suction force acting on it on the other hand, there is also fluttering or hitting the filter material in the dust collecting space, so that the multi-layer nonwoven material of the vacuum cleaner bag is knocked out.
- the elastic means can be directly in operative connection with the filter material.
- the filter material may be formed of multiple layers and one of the layers may be elastic.
- Another embodiment of the direct action of the elastic means may also be that elastic bands are arranged on the filter material. Such a bag is very easy to manufacture.
- the elastic means is formed of an elastic fabric or net, which cooperates with the filter material.
- the elastic fabric, mesh or elastic bands may also be attached to the inside of the bag.
- the elastic fabric or mesh loosely envelops the pouch and thereby does not interfere with the flow of air.
- the elastic fabric or mesh is also very easy to attach to the support plate.
- Elastic material may also preferably be applied by spraying on the inside or outside of the bag. This should be done either partially or with an air-permeable material.
- a method designed according to the invention for producing a vacuum cleaner bag wherein elastic bands are arranged on the filter material, at least a first portion of the vacuum cleaner bag is folded onto the opposite side of the holding plate and the elastic bands are in relaxed or only slightly tensioned state on the one hand on the folded Section and on the other hand attached to other sections of the vacuum cleaner bag.
- the elastic bands can be secured in the relaxed or slightly tensioned condition, which simplifies manufacturing.
- the bag has only a small footprint in this state, which simplifies its storage. Also, the insertion of the bag in the lo dust collection chamber of the vacuum cleaner is simplified.
- At least two further sections are folded onto the side opposite the holding plate before folding the first section transversely to its folding direction.
- at least one elastic band should be attached to the central region of the first folded portion and to an unfolded portion. In this way, i 5 is ensured that the bag in the unfolded state is surrounded on all sides by elastic bands.
- the elastic bands are in this state on the side facing away from the plate and therefore do not interfere with the insertion into the receptacle of the vacuum cleaner.
- the means can also interact with the bag indirectly.
- means may be provided in the dust collecting space which compress the receiving volume of the bag in a state unfolded in the dust collecting space when the suction air is switched off.
- the indirect means in the dust collecting space comprise elastic means whose restoring elasticity force 2 5 is less than the suction force acting on the bag.
- spring elements such as spring-loaded plates, for this purpose can be arranged in isolation in the dust collecting space, which make the volume reduction when the fan is switched off.
- elastic bands or an elastic fabric or mesh are used, which envelop the bag. These may be attached to a receptacle located in the 30 Staubsammelraum for the holding plate of the bag. The advantage would be that even conventional vacuum cleaner bags can be used, which is not yet involved a direct-acting elasticity.
- Figure 1 a is a sectional side view of a vacuum cleaner with a
- Dust collection room in which the vacuum cleaner bag is shown with the vacuum cleaner off;
- Figure 1b is a view according to Figure 1a, in which the vacuum cleaner is turned on and the vacuum cleaner bag is expanded;
- Figure 2a is a front view of a folded vacuum cleaner bag
- Figure 2b shows the rear view of the vacuum cleaner bag
- Figure 2c shows the rear view of the vacuum cleaner bag with elastic bands
- Figure 3 is a partially sectioned view of a vacuum cleaner with a dust collecting space and an elastic net applied to the bag in the
- Figure 4 is a further, partially sectioned view with a dust collecting space and one or more bands attached to the housing for compression of the
- Figure 5 is another illustration of an embodiment of the invention having a spring assisted plate for compressing the bag in the condition that the vacuum cleaner is off and the bag is compressed ( Figure 5a) and in the condition that the vacuum cleaner is on and the vacuum cleaner bag is widened ( Figure 5b).
- FIGS 1a and 1b show in a side view purely schematically a canister vacuum cleaner 1.
- This has in the front part of its housing 2 a dust collecting space 3 for insertion of vacuum cleaner bags 4.
- a receptacle 5 for the holding plate 6 (see Figure 2a) of the vacuum cleaner bag 4 is arranged.
- the vacuum cleaner bag 4 is then closed lid 7 with its inlet opening 8 behind the intake 9 of the vacuum cleaner 1.
- suction air symbolized in the figure 1a by the arrows 10 and 11 to be able to pass through the vacuum cleaner bag 4 is in the rear of a fan 12th arranged, which is directed with its suction side to the dust collecting space 3.
- an actuating button 23 is provided for switching on - then the suction air flows via the intake connection through the vacuum cleaner bag 4 to the blower 12 and from there via an exhaust air filter 24 into the environment.
- the vacuum cleaner bag 4 is formed from an air-permeable filter material and provided with an inlet opening for the air to be filtered, indicated in the figure 1a, b with the arrow 10th
- the bag corresponds to its receiving volume, as shown for example in Figure 1 b, as the dust collection chamber 3 of the vacuum cleaner 1.
- the bag is able to support volume to reduce in the dust collecting space 3 when the blower 12 is turned off, so no suction air flows through the dust collecting space 3.
- the bag 4 acts to reduce the receiving volume, as can be seen in Figure 1a, together with elastic means whose restoring elasticity force is smaller than the suction force of the fan 12 and compress it in this way when switching off the suction air.
- the elastic means are directly in operative connection with the filter material. Since vacuum cleaner bags 4 are usually offered to suit a limited number of vacuum cleaner types from a manufacturer, the elasticity of the bag 4 can be adapted to the fan performance of the particular vacuum cleaner type.
- Figures 2a and 2b show a vacuum cleaner bag 4 according to the current state of the art in a state in which it is in its sales packaging.
- FIGS. 3a and 3b show a further embodiment of the invention, in which an elastic network structure 22, which loosely envelopes the bag 4, causes its compression.
- the switched-off state of the vacuum cleaner fan 12 is shown in Figure 3a, so that the elasticity force of the network 22 causes a reduction of the bag volume.
- the elasticity force of the network structure 22 is designed so that it is smaller than the suction force in the switched-on state of the device, which leads to the expansion of the bag 4 shown in FIG. 3b when the blower 12 is switched on. Variants are conceivable for this embodiment.
- the elastic network structure 22 is an integral part of the vacuum cleaner bag 4 and is attached directly to the holding plate 6.
- the second variant not shown in the figures, the
- Fixing point be the holding plate holder 5 of the vacuum cleaner 1, so that the network structure 22 is an integral part of the vacuum cleaner 1 and the bag 4 is inserted laterally in such a case when inserted into the network structure 22.
- a vacuum cleaner bag 4 constructed according to the invention whose elastic properties s can also be brought about by the fact that in a filter material, which is formed from a plurality of layers, the elastic means between the layers are involved. It is also conceivable that in a multilayer filter material, for example, as an elastic means an elastic fabric can be integrated, which cooperates with the filter material. Likewise, an arrangement of elastic bands, elastic fabric or a lo elastic net on the inside of the vacuum cleaner bag 4 is conceivable. Elastic material can also be applied from the inside or from the outside on the bag 4 by spraying. This should be done either partially or with an air-permeable material.
- the vacuum cleaner bag 4 also has the possibility that the elastic means i 5 are indirectly in operative connection with the bag 4.
- a means can be arranged in the dust collecting space 3, which likewise reduces the receiving volume of the vacuum cleaner bag 4 when the suction air is switched off.
- the indirect means may comprise spring elements whose spring force is designed to be smaller than the suction force, so that a compression of the bag 4 can be caused from the outside.
- Figures 4a and 4b show a first embodiment of this variant.
- elastic bands 25, one example of which is shown here arranged such that the ends 26 of the bands are fixedly attached to the bottom plate 27, the elastic bands 25 include the vacuum cleaner bag 4 and the loose ends 28 by the user non-positively on the Recording 5 are attached.
- the elastic bands 25 include the vacuum cleaner bag 4 and the loose ends 28 by the user non-positively on the Recording 5 are attached.
- FIG. 4b shows this embodiment in the switched-on state of the blower 12.
- the air entering through the inlet opening flows through the air-permeable material of the bag 4.
- the elastic force of the elastic bands 25 is dimensioned in such a way that that
- the vacuum cleaner bag 4 so far expands by the suction that he almost completely fills the dust collection chamber 3 of the vacuum cleaner 1.
- FIGs 5a and 5b show an embodiment of a vacuum cleaner 1 constructed according to the invention, in which the reduction of the bag volume is produced by the action of a movable plate 29.
- the holding plate 6 of the vacuum cleaner bag 4 is inserted into the 3 5 holding plate holder 5 of the vacuum cleaner 1.
- the effective force of the plate 29 is achieved by a spring 30 which extends to the partial wall 31 between the dust collecting space 3 and Blower chamber 32 is supported and whose spring force is designed so that it reduces the volume of the vacuum cleaner bag 4 in the off state of the blower 12 ( Figure 5a). Air is sucked through the suction port 8 and flows through the filter material of the bag 4.
- the spring force of the spring 30 is designed so that the spring is compressed by the suction force acting on the movable plate 29 and the bag 4 fills the dust collecting space 3 as shown.
