Description

The present invention relates to a vacuum cleaner with a vacuum cleaner housing, the vacuum cleaner housing having a receiving device for receiving a cyclone dust separator unit comprising a primary cyclone dust separator and a secondary cyclone dust separator unit with a plurality of secondary cyclone dust separators, with an air outlet of the The primary cyclone dust separator is connected via a distribution duct system to the air inlets of the secondary cyclone dust separator, the primary cyclone dust separator being provided with a primary dust collection container and the secondary cyclone dust separator unit being provided with a secondary dust collection container unit having at least one secondary dust collection container wherein the secondary cyclone dust collectors of the secondary cyclone dust collector unit form a plurality of secondary cyclone dust collector groups, each arranged in a row arrangement extending at least partially along a side edge of the cyclone box a trained and interchangeably arranged on the vacuum cleaner housing cyclone dust separator unit, wherein the air inlets of the secondary cyclone dust separator are arranged together with the air outlet of the primary cyclone dust separator in a common air duct level with the distribution channel system.

From the EP 2 677 915 B1 a vacuum cleaner is known which has a cyclone dust separator unit in a receiving device of the vacuum cleaner housing designed as a carriage. In the case of the sled construction, the housing is provided with rollers and/or glides so that the vacuum cleaner can be pulled over the floor using a suction hose connected to the housing.

In the known vacuum cleaner, to achieve a space-saving arrangement of the cyclone dust separator unit, the primary cyclone dust separator and the secondary cyclone dust separator are arranged in different positions on the housing, with the primary cyclone dust separator on the top and the secondary cyclone -Dust separators are located on the front of the vacuum cleaner housing. In order to connect an air outlet of the primary cyclone dust separator to the air inlets of the secondary cyclone dust separator, it is therefore necessary for an air duct to extend from the rear of the housing to the front of the housing, where it merges into a distribution duct system to which the air inlets of the Secondary cyclone dust separators are connected.

The configuration of the cyclone dust separator unit described results in an arrangement of the cyclone dust separator unit in which it is placed on the housing in a saddle-like manner. Due to the complex design of the cyclone dust separator unit, the housing design must be specially adapted to the cyclone dust separator unit in order to combine the cyclone dust separator unit with the housing, so that the cyclone dust separator unit can be exchanged for dust separator units such as those used for dry vacuuming using dust bags or used for wet vacuuming and which are arranged inside the housing in a receiving chamber is not possible.

The US 2016 / 0 088 989 A1 describes a vacuum cleaner with a plurality of secondary cyclone dust separator groups, each of which is arranged in a row, with the air inlets of the secondary cyclone dust separators not lying in a common air flow plane LF together with the air outlet of the primary cyclone dust separator. Furthermore, only the upper group extends along a side edge and not the lower group. Furthermore, the outlet air flow from the primary cyclone dust separator is directed vertically upwards and the inlets of the secondary cyclone dust separators are rotated horizontally by 90°. The air must therefore overcome an angle of 90° in order to be able to get from the outlet of the primary cyclone dust separator to the inlets of the secondary cyclone dust separator.

The U.S. 2016/0 095 483 A1 describes a vacuum cleaner according to the preamble of claim 1, wherein in particular the air outlet of the primary cyclone dust separator lies with the inputs of the secondary cyclone dust separator in a common air duct level and a distribution channel system is provided there.

The present invention is therefore based on the object of proposing a vacuum cleaner which can be interchangeably fitted with dust separator units which are designed in different ways or operate according to different principles.

To solve this problem, the vacuum cleaner according to the invention has the features of claim 1.

According to the invention, the secondary cyclone dust separators of the secondary cyclone dust separator unit form a plurality of secondary cyclone dust separator groups, each arranged in a row arrangement extending at least partially along a side edge of the cyclone nbox trained and interchangeably arranged on the vacuum cleaner housing cyclone dust separator unit, wherein the air inlets of the secondary cyclone dust separator are arranged together with the air outlet of the primary cyclone dust separator in a common air duct level with the distribution channel system.

Due to this advantageous design of the cyclone dust separator unit, a compact design as a cyclone box is possible, so that the cyclone dust separator unit can be arranged inside the housing in a receiving chamber, comparable to the arrangement of a dust separator unit provided with a dust bag or a dust separator unit of a wet vacuum cleaner, and This means that the different dust separator units can be exchanged with one another without having to make any changes to the housing.

In particular, the arrangement of secondary cyclone dust separators in at least two groups, each arranged in a row arrangement, allows for an arrangement of the secondary cyclone dust separators along the side walls of the cyclone box, with due to the arrangement of the air inlets of the secondary cyclone dust separator and of the air outlet of the primary cyclone dust separator in a common air duct level, this air duct level can be executed parallel to a side wall of the cyclone box.

It is emphasized that the formation of a row arrangement of the secondary cyclone dust separators does not require a rectilinear arrangement of the secondary cyclone dust separators, but allows this as an embodiment, so that, for example, an arrangement of the groups parallel to side edges is possible.

Overall, an approximately cuboid configuration of the cyclone dust separator unit is possible, which also allows the cyclone dust separator unit to be accommodated in conventionally designed accommodation chambers that serve to accommodate dust separator units with dust bags or dust separator units of a wet vacuum cleaner.

According to the invention, the distribution channel system is provided with a cyclone cover with at least one suction opening, such that when the receiving device is designed as a suction chamber between the cyclone cover of the distribution channel system and a housing cover of the vacuum cleaner housing that is provided with a suction opening, a closed suction space is formed and thus not only the problem-free accommodation of the cyclone -Dust separator unit is possible in a housing of a vacuum cleaner, which is used, for example, to hold a dust separator unit with a dust bag, but that the cyclone dust separator unit can also be easily operated without having to make any adjustments to the housing cover.

If, in a particularly preferred embodiment, the distribution channel system is formed on a plate-shaped cyclone carrier, the cyclone carrier divided from one another transversely to the longitudinal direction of the housing has a primary cyclone area for arranging the primary cyclone dust separator and at least one secondary cyclone area for arranging the secondary cyclone Has dust separator, in a first embodiment, the design of a cyclone dust separator unit as a cyclone box with secondary cyclone dust separators can be selected, all of which are arranged on one side of the primary cyclone dust separator, so that there is also a correspondingly advantageous spatial separation between a primary dust collection container on one side of the cyclone box and a secondary dust collection container unit on the other side of the cyclone box.

In a further advantageous embodiment, the cyclone carrier has a central primary cyclone area, separated from one another transversely to the longitudinal direction, for arranging the primary cyclone dust separator and two secondary cyclone areas, each formed on the side of the primary cyclone area, for arranging secondary cyclone groups of the secondary cyclone dust separator unit on, so that a symmetrical design of the cyclone box is made possible.

Irrespective of whether an asymmetrical or symmetrical design of the cyclone box is selected, it is particularly advantageous if a cyclone tube of the primary cyclone dust separator and cyclone tubes of the secondary cyclone dust separator are formed on the cyclone carrier, so that essential components of the cyclone box are already in Combination is realized with the cyclone carrier and thus not only allows a particularly compact design of the cyclone dust separator unit, but also the number of items required to assemble the cyclone box can be significantly reduced.

It is particularly advantageous if the cyclone carrier is arranged on a lower housing part of the cyclone box in such a way that the primary dust collection container and the secondary dust collection container unit are arranged in a row in a common housing base designed as a lower housing part and detachably connected to the cyclone carrier and the primary dust -Collective container has a cover arranged on a side wall or on the bottom of the lower housing part. Thus, the lower housing part, which serves as the housing base for accommodating the cyclone carrier, is also designed as a collection container for the primary dust and the secondary dust, with the cover allowing separate emptying of the primary dust collection container.

It is particularly advantageous if the secondary dust collection container unit has two secondary dust collection containers, the primary dust collection container being arranged between the two secondary dust collection containers to form the row arrangement.

The cover is preferably designed as a pivoting cover, with a pivoting axis arranged on the upper edge of the cover, so that residual emptying of the coarse dust from the primary dust collection container is possible without the cover being a hindrance.

It is also advantageous if the at least one secondary dust collection container has a removable cover with a large number of openings assigned to the individual secondary cyclone dust separators for the input of secondary dust, so that it is possible to open the cyclone tubes of the secondary cyclone dust separator down to introduce the secondary dust collection container while preventing a cover of the secondary dust collection container to protect contamination of the interior of the cyclone box with fine dust.

Contamination of the interior of the cyclone box can be avoided particularly effectively if the openings serve to receive end pieces of the cyclone tubes of the secondary cyclone dust separator in a form-fitting manner, such that opening edges of the openings enclose the end pieces.

Advantageous embodiments of the invention are explained in more detail below with reference to the drawing.

1 shows a vacuum cleaner housing 20 in a carriage design with a cyclone box 23 accommodated in a housing body 21 designed as an accommodation chamber 22, the accommodation chamber 22 having a housing cover 24 ( 2 ) is provided, which is provided with a suction opening 25 designed as a connecting device, to which a suction line (not shown here) can be connected, which is provided at its other end with a suction head designed, for example, as a suction brush.

4 shows the cyclone box 23 in an individual representation, with its construction or the components required for the construction of the cyclone box 23 in 7 are shown. Like a synopsis of 4 and 7 can be seen, the cyclone box 23 has a cyclone carrier 26 as its essential components, which is plate-shaped and here approximately rectangular in shape and has a primary cyclone area 27 and a secondary cyclone area 28 arranged in a row in a direction transverse to the longitudinal axis L of the vacuum cleaner housing 20. On a central axis M of the cyclone box 23 is an intake manifold 29, which is arranged on the underside of the cyclone carrier 26, is provided with a tangential inflow channel 30 and is designed as a cylinder cyclone tube 31 of a particularly also in 3 illustrated primary cyclone dust separator 32 opens.

In the case of the present illustration, the cyclone tube 31 is independent of the cyclone carrier 26 dependent component is formed, which is bonded to the underside of the cyclone carrier 26 when the cyclone box 23 is formed. Also on the underside of the cyclone carrier 26 extends a conical immersion tube 33 of the primary cyclone dust separator 32 in the present case, which is arranged in an air duct plane LF defined by the cyclone carrier 26 with an opening which has an air outlet 34 of the primary cyclone Dust separator 32 forms.

In the secondary cyclone area 28 of the cyclone carrier 26 there is a secondary cyclone dust separator unit 47 composed in the present case of three secondary cyclone dust separator groups 35, 36 and 37. The secondary cyclone dust separator groups 35, 36 and 37 each have a plurality of Secondary cyclone dust separators 38, which are arranged in a row arrangement 39, 40 and 41, the two row arrangements 39, 40 each extending along a side edge 42, 43 of the cyclone box 23, here at a corner, and the row arrangement 41 below is arranged at an angle to the side edges 42, 43 and extends from a side edge 44 starting obliquely inwards.

Conical cyclone tubes 45 of the secondary cyclone dust separator 38 are formed on the cyclone carrier 26 and extend from the underside of the cyclone carrier 26 . To combine the secondary cyclone dust separator 38, a cyclone cover 46 is arranged on top of the cyclone carrier 26, which, in particular, a synopsis of the 7 and 8th makes clear, is provided on its underside with channel webs 94, which, like 6 shows, in combination with the cyclone carrier 26, form tangential inflow channels 48 for the secondary cyclone dust separator 38 and a distribution channel system 49, such that in the air routing plane LF defined by the cyclone carrier 26, the air outlet 34 with air inlets 50 formed by means of the inflow channels 48 is the secondary -cyclone dust separator 38 are connected.

For the formation of air outlets 51 of the secondary cyclone dust separator 38, as in particular in 5 shown, formed on the cyclone cover 46 dip tubes 52 having an opening in the cyclone cover 46.

How further 7 can be seen, in the present case it is provided to arrange a housing seal 95 between the cyclone carrier 26 and the cyclone cover 46 .

The cyclone carrier 26 is arranged on a lower housing part 54 in such a way that the cyclone tube 31 of the primary cyclone dust separator 32 and the cyclone tubes 45 ( 5 ) the secondary cyclone dust separator 38 extend into the lower housing part 54, the lower housing part 54 having a partition 57 for division into a primary dust collection container 55 and a secondary dust collection container 56, such that the cyclone tube 31, at its lower end there is a primary dust discharge port, into the primary dust collection tank 55 and the cyclone tubes 45, which have a secondary dust discharge port at their lower end, protrude into the secondary dust collection tank 56 and are separated from each other by the partition wall 57.

How in particular 7 shows, the lower housing part 54 is releasably connected to the cyclone carrier 26 via lever lugs 58 which are connected to the lower housing part 54 via an eccentric axis 59 pivotably mounted in the lower housing part 54 . For a secure connection, locking webs 60 are formed on the upper side of the cyclone carrier 26, which are engaged behind by locking claws 61 of the lever lugs 58 when a connection is made between the lower housing part 54 and the cyclone carrier 26.

A pivoting cover 62 is arranged on a front side wall 101 of the lower housing part 54 and, in its closed position, covers an emptying opening 63 formed in the side wall 101 only in the region of the primary dust collection container 55 . To form a pivot bearing, the pivot lid 62 is mounted at its upper lid edge 64 by means of a pivot axis 65 in bearing receptacles 66 formed on the side wall 101 . A seal is provided between an opening edge 67 of the discharge opening 63 and the pivoting lid 62 . In order to lock the pivoting cover 62 in its closed position, the pivoting cover 62 in the present case has a locking mechanism 68 with a drive wheel 69 which is mounted in the pivoting cover 62 and is accessible from the outside and which, via toothing devices 72 formed on the drive wheel 69 and on the locking disks 70, 71, prevents the locking disks 70 from rotating , 71 in such a way that a screw flank 73 formed on the locking disks 70, 71 engages in locking latches 74 which are formed on a locking web 75 of the lower housing part 54. The above-described locking mechanism 68 of the pivoting cover 62 enables simple operation on the one hand and secure holding of the pivoting cover 62 in its closed position on the other, even if a strong overpressure develops in the lower housing part 54.

How in particular from a synopsis of 5 and 7 shows, a dust cover 76 is provided to cover the secondary dust collection container 56, which has openings 77 is provided, which correspond to the distribution and number of cyclone tubes 45 of the secondary cyclone dust separator 38 in terms of their distribution and number in the dust cover 76 . How 5 shows, the immersion tubes 52 with end pieces 78 penetrate the openings 77 in such a way that opening edges 79 of the openings 77 enclose the end pieces 78, so that fine dust collected in the secondary dust collection container 56 is prevented from entering the interior of the cyclone box 23 outside of the secondary dust collection container 56 contaminated. In particular, if an annular elastic seal is provided on the opening edges 79, which nestles against the end pieces 78, it can be prevented that, when the housing lower part 54 is separated from the cyclone carrier 26, for example an emptying of the primary dust collection container 55 and/or of the secondary dust collection container 56, fine dust adhering to the end pieces 78 of the dip tubes 52 escapes from the secondary dust collection container 56 in such a way that fine dust possibly adhering to the end pieces 78 is scraped off the end pieces 78 like a squeegee when the cyclone carrier 26 is separated from the lower housing part 54 becomes.

The 9 until 13 serve to explain a cyclone box 80, in contrast to that in the 1 until 8th illustrated asymmetrically designed cyclone box 23, which has secondary cyclone dust separators 38 only on one side of the central axis M, is symmetrically designed with a central primary cyclone area 99 and two secondary cyclone areas 100, each arranged to the side of the primary cyclone area 99. As shown in particular in 12 shows, the symmetrical design of the cyclone box 80 results from a symmetrical design of a cyclone carrier 81, which has two row arrangements 82, 83 of secondary cyclone dust separators 38 of a secondary cyclone dust separator unit 96 on both sides of the central axis M, the secondary cyclone dust separators 38 are disposed along opposite side edges 84, 85 of the cyclone box 80, respectively, of a secondary cyclone dust separator group 97,98. Corresponding to the cyclone carrier 26 of the cyclone box 23, cyclone tubes 45 of the secondary cyclone dust separator 38 are also formed on the cyclone carrier 81 and extend from the underside of the cyclone carrier 81, with openings of the cyclone tubes 45 in the air duct plane defined by the cyclone carrier 81 LF are arranged.

The primary cyclone dust separator 32 is located on the cyclone carrier 81, as is the intake port 29, on the central axis M of the cyclone box 80.

From the compared to the cyclone carrier 26 changed arrangement or distribution of the secondary cyclone dust separator 38 results in a correspondingly different design of a cyclone cover 86, the formation of a distribution channel system 87 on the cyclone carrier 81, as in particular from 13 can be seen, has duct webs 94 on the underside, which extend radially from a distribution area 105 of the cyclone cover 86 that covers the air outlet 34 of the primary cyclone dust separator 32, which lead to air inlets 88 of the secondary cyclone dust separator 38 and there via tangential inflow sections 89 into the Air inlets 88 open out. Within the air inlets 88, in correspondence with the air inlets 50 of the cyclone box 23, dip tubes 52 are formed which form air outlets 51 of the secondary cyclone dust separators 35.

How in particular 12 further shows, the symmetrical arrangement of the row arrangements 82, 83 of the secondary cyclone dust separators 35 with respect to the central axis M of the cyclone box 80 results in a correspondingly symmetrical design of a lower housing part 90 of the cyclone box 80. The lower housing part 90 has a central primary dust collection container 91, to which secondary dust collection containers 92 are formed laterally adjoining the side walls 102, 103 in such a way that the cyclone tube 31 of the primary cyclone rod separator 32 enters the primary dust collection container 91 and the cyclone tubes 45 of the secondary cyclone dust separator 38 are accommodated in the secondary dust collection containers 92. Like the primary dust collection container 55 of the lower housing part 54 of the cyclone box 23, the primary dust collection container 91 of the cyclone box 80 is also provided in a front side wall 104 with a pivoting cover 62, which has already been described above with reference to FIG 7 explained locking mechanism 68 has.

The secondary dust collection containers 92 formed in the lower housing part 90 are each equipped with a dust cover 93 (see also 10 ) provided, which corresponds to the dust cover 76 of the secondary dust collection container 56 of the cyclone box 23 with openings 77 for receiving end pieces 78 of the cyclone tubes 45 of the secondary cyclone dust separator 38.
