Description

Filter unclogging device for vacuum cleaner

technical field

[01] The present invention relates to the field of vacuum cleaners employing a step of separating garbage by a pleated type filter.

Background technique

[02] By far the most commonly used vacuum cleaners use a paper filter placed between the electric ventilator and the intake duct to separate dust and debris. The reduction of air pollution takes place through said paper filters or filters made of non-woven material, mechanically trapping particles larger than the pores of the filter media.

[03] This kind of filtration is easy to cause the filter medium to be gradually clogged during use, until the suction and cleaning power drops to the limit, thus requiring replacement of the filter.

[04] Ordinary vacuum cleaners using filters for separating particles have the double disadvantage of causing a loss of suction power at any time and, when saturated, requiring replacement of the filter media. This increases the cost for the user.

[05] In addition, when the filter bag is replaced, the fine dust present on the surface of the dust collecting area may contaminate the user. Furthermore, this unpleasant maintenance operation sometimes leads to unintended waste discharges into the environment.

[06] In order to solve these problems, a bagless vacuum cleaner has been proposed which uses cyclone or inertial separation to remove garbage.

[07] In this type of vacuum cleaner, the polluted air enters tangentially into a separation chamber equipped with a grid or primary separator that removes coarse particles and then into a secondary separator that removes remaining fine particles. in the stage separator. Such a vacuum cleaner is described in detail in the applicant's patent application EP1535562.

[08] The inertial separation vacuum cleaner described in the document EP1535562 is equipped with an air inlet duct through which the air passes in a tangential direction into a primary waste separation chamber, said chamber being generally cylindrical in shape. The central part of the chamber leads to a duct, which is connected to a suction device, and said duct is equipped with secondary filtering equipment to remove finer particles.

[09] The discharge pipe can recycle the centrifuged garbage in the sealed collection box. The waste discharge duct is located at the same height as the air inlet, arranged in a position substantially completely opposite to the axis of the cylindrical separation chamber.

[10] For example as detailed in the aforementioned document EP1535562, the filter assembly received in the central part of the vacuum cleaner has a primary filter assembly and a secondary fine filter assembly for filtering the waste carried by the air flow.

[11] The airflow in the separation chamber enters tangentially and is discharged to the central part of the separation chamber, so it is a vortex passing path, which is beneficial to the separation of garbage.

[12] The primary filter assembly is positioned in the main separation chamber, in the upper part of the filter assembly, and consists of a mesh-shaped cylindrical section perforated to allow the passage of airflow in the direction of the secondary filter chamber.

[13] The main separation chamber, especially its geometry, and the grids used to separate large-sized refuse, are configured to perform centrifugation as efficiently as possible. In fact, most of the waste collected by the suction device is discharged directly into the waste collection box.

[14] The fine fraction of garbage, especially dust with small particle size, passes through the primary filter grid, so secondary filtration must be performed before the air is discharged through the suction device.

[15] This secondary filtration is traditionally constituted by a cylindrical origami filter arranged coaxially with the primary separation chamber.

[16] Contrary to what happens in ordinary vacuum cleaners, most of the waste is removed by the primary filter before reaching the fine filter which constitutes the secondary filter. As a result, it takes a long time for the filter to become clogged, and maintenance work by the user on this part of the vacuum cleaner does not take place very often.

[17] As for ordinary vacuum cleaners, the clogging of the filter is easy to cause the loss of suction power and the gradual ineffectiveness of the vacuum cleaner. Such maintenance interventions occur infrequently and thus constitute a necessary constraint for the vacuum cleaner to work well.

[18] It is known that the vacuum cleaner proposed by the document US5307538 has a first cyclone filter, and then the air is transported towards the power module through the filter. Preferably, the filter is a metal fine filter which can be cleaned with a small brush supplied with the vacuum cleaner.

[19] However, this unclogging device of the filter requires user intervention on the one hand, and on the other hand produces a relatively large contact with the fine dust accumulated in the pores of the filter. Furthermore, this operation has to be carried out after the vacuum cleaner has been partially disassembled, making it inconvenient to handle.

[20] It is known that the vacuum cleaner proposed by the document FR2027213 is equipped with a pleated filter, which filters the inhaled dust and garbage, and a filter cleaning member which strikes the filter Wrinkle apex to remove dust attached to the filter, these members are applied by the winding disc during the power cord rewinding operation.

[21] Thus, this type of vacuum cleaner already automates the unclogging operation of the filter, and if the user does not rewind his power cord, or if only a small length of power cord is unwound, then this operation may not be performed or only partially conduct. Furthermore, such a device is complicated to use if the take-up disc is located far from the filter to be unclogged.

Contents of the invention

[22] Therefore, the present invention aims to improve the vacuum cleaner, which has the primary separation of garbage (by centrifugal separation, inertial separation, water filtration or large mesh filter) and the secondary separation of finer garbage, proposing the secondary fine filter Clear blockage, reduce user maintenance as much as possible, and simple to implement.

[23] The present invention relates to a waste separation device for a vacuum cleaner with a filter system, said device having a pleated filter and a clogging device for said filter, said clogging device having at least one mechanical actuation element, which supports On the wall of the filter, one of the parts in the filter or the mechanical actuation element is movable relative to the other, characterized in that the separating device is a secondary separating device arranged downstream of the primary filter system, characterized in that it is also In that the motorized reducer automatically implements the relative mechanical movement between the mechanical actuation element and the filter.

[24] Advantageously, the primary filtration is carried out by cyclone phenomenon or by inertia in a separation chamber connected to the refuse collection box, so that a large amount of refuse can be separated.

[25] According to a preferred embodiment of the present invention, the pleated filter is in the shape of a tube, and the relative movement between the mechanical actuation element and the filter is a circular movement. The tubular feature of the secondary filter saves space while providing a large filter spread throughout.

[26] Therefore, the main advantage of the unclogging device of the present invention is to reduce the maintenance operations on the filter assembly and reduce the replacement cost of the filter. The device also limits the power losses associated with clogging of the filter, so that the performance of the cleaner remains constant over time.

[27] The hygienic conditions of using a vacuum cleaner can be greatly improved without user intervention on the filter assembly.

Detailed ways

[38] Figure 1 shows a cyclonic cleaner with the present invention, which generally consists of a base 1 supported by a wheel body 2 and front guide wheels 3, allowing movement and orientation of the cleaner during its operation.

[39] The power module 4 is arranged at the front of the vacuum cleaner. The input air flow laden with waste enters the receiving port 5 and enters tangentially into the main separation chamber 6 .

[40] The main separation chamber 6 has an opening 20 for discharging the waste toward a waste collection box 37 . A conduit 8 connects between the refuse collection box 37 and the main separation chamber 6 .

[41] The cyclonic cleaner has a filter assembly 9 formed by a main separation chamber 6 and a body 15 delimiting a cylindrical chamber 12 for a secondary filter 13, the two chambers Located in the immediately lower portion, the two chambers are in pneumatic relationship to each other.

[42] FIG. 2 is a top view of the filter assembly (without the primary filter 17), which shows that the airflow laden with waste enters the receiving port 5 tangentially, and the purified air is discharged by the duct 11 to the upper part of the power module 4 . In this configuration, the entry and exit of air take place practically at the same height, the flow in the filter assembly 9 being defined for optimal separation of the waste.

[43] According to the embodiment of the invention shown in FIGS. 1 to 6, the vacuum cleaner has a motorized reducer (moto-réducteur) 10, which is arranged on the base 1 and operates the unclogging device of the filter constituting the secondary separation, power The module 4 is vertical and the secondary filter device is a pleated tubular filter vertically oriented in the filter assembly 9 .

[44] FIG. 3 is a sectional view along the vertical plane A-A of the filter assembly shown in FIG. 2 . The sectional view shows the positioning of the main separation chamber 6 in the upper part of the filter assembly 9, the receiving opening 5 and the exhaust duct 11, the secondary filter chamber 12 is equipped with a pleated tubular filter 13 and a mechanical actuation element 23, which is positioned On the axis of the filter assembly, the filter assembly is generally cylindrical.

[45] The filter module 9 has a clogging device 14 of the secondary fine filter 13 at its central bottom.

[46] More precisely, FIG. 4 shows the different constituent parts of the filter assembly 9, and in particular:

[47] The main body 15, which defines the secondary filter chamber 12 and protects the filter components,

[48] The main separation chamber 6, which is positioned in the upper part of the main body 15, has an opening 20 towards the connection duct 8, leading to the waste collection box 37,

[49] Primary filter 17 perforated, for example as described in patent EP1535562,

[50] Obturator 18, which retains the group of detachable components locked in the filter assembly and closes the main separation chamber,

[51] The delivery elbow 16, which orients the air from the pleated filter 13 towards the tube 11 and then towards the suction power module, is located below the main separation chamber, and is connected centrally with the tubular filter A partially connected dome body 162 is formed which partially delimits an opening 164 connecting the inner part of the primary filter 17 to the outer part of the pleated filter,

[52] A tubular pleated filter 13 positioned vertically in the central and lower portion of the main body 15, the lower portion of which forms a secondary separation chamber,

[53] Unblocking device 14, which is acted upon by motorized reduction gear 10 via transmission 19.

[54] The exploded view shown in Figure 4 and the cross-sectional view shown in Figure 3 provide a better understanding of the flow of air in the filter assembly. The dust-laden air enters the main separation chamber 6 tangentially through the receiving opening 5, the high-speed air flow turns in the direction F around the annulus formed between the primary filter 17 and the wall of the chamber 6, and discharges coarse waste through the opening 20 (arrow F ₁ ). The rubbish of these thick rubbish is discharged towards recycle bin 37.

[55] Thus, the airflow enters the pores of the primary filter 17 and then, through the opening 164, enters the secondary filter chamber between the main body 15 and the pleated filter (arrow _F2 ). Air thus passes through the filter from the outside towards the inside, removing residual dust and fine particles as it passes, and rising into the central and upper tubular portion of said pleated filter 13 (arrow F ₃ ).

[56] The dome body 162 is located in the upper part of the filter assembly, forming the delivery elbow 16 of the filtered air, which orients the air flow towards the duct 11 and the power module acting as the suction (arrow _F4 ).

[57] The clogging device of the present invention is hermetically arranged at the lower part of the filter assembly so as not to interfere with the flow of air in the filter assembly and not to hinder the separation of particles under centrifugal force.

[58] Thus, the drive mechanism of the movable member is positioned under the tubular filter 13 and the mechanical actuation element is positioned inside the tubular filter 13 . In other embodiments, the mechanical actuation element may be located on the outside of the tubular filter 13 .

[59] The unclogging device 14 is located in the lower part of the filter assembly, which facilitates the cleaning and replacement operations of the filter, especially because after the stopper 18 is unlocked and the aforementioned detachable components are removed, it can be removed by the upper part of the filter assembly. close to the filter.

[60] As shown in FIGS. 4 and 5 , the unclogging device has a motorized reduction gear 10 acting rotationally on a mechanical actuation element 23 via a transmission 19 .

[61] The transmission 19 is preferably located below the filter 13 and its function is to transmit rotation between the drive shaft of the motorized reducer 10 and the support shaft 22 of the mechanical actuation element 23 . The drive shaft is offset from the central axis of the generally cylindrical filter assembly 9 .

[62] Thus, according to this embodiment, the mechanical actuation element is movable and the filter 13 is fixed.

[63] As shown in Figure 5, the transmission 19 may for example have a wheel train 24 connected by a drive belt 21, or any other means capable of transmitting rotational motion between one point and another.

[64] The mechanical actuation element 23 may for example be in the form of a finger which scrapes against the folds of the filter 13 in order to cause the dust to fall when they are turned. These fingers can be positioned in the middle portion, substantially at half-height of the tubular pleated filter, or elsewhere, depending on its shape and configuration of the filter.

[65] At least two mechanical actuation elements 23 are arranged at the ends or on the shaft 22 used as a support, advantageously, a larger number of said elements, usually six, are arranged, which are also distributed in the tubular filter It can also be distributed over the height of the filter, while being arranged at different heights on the axis 22.

[66] The mechanical actuating element 23 can also be a metal wire bent into an arc, fixed on one side to the lower part of the shaft 22, and on the other side to the upper part of the shaft, located in the pleated filter the upper position. According to this embodiment, the convex outer part of the metal arc bears on the filter, and the friction caused by the rotation causes dust to fall, unclogging the filter.

[67] The rotational mechanical actuation elements for shaking the pleated filter may also consist of blades or paddles.

[68] Other different rigid or flexible components are contemplated for mechanically agitating the filter to dislodge the dust by gravity without departing from the scope of this invention.

[69] The secondary filter incorporated in a cyclonic cleaner having the present invention may be formed from different materials and any filter medium known in the art, be it paper, non-woven or fabric.

[70] A preferred embodiment of the invention is shown in Figures 1 to 6, however, there are various embodiments for designing a vacuum cleaner of the aforementioned type with a secondary filter clogging device of the invention.

[71] So arranged, the vacuum cleaner discharges the largest and heaviest waste during primary separation. The finest rubbish consists essentially of fine dust, which is filtered out by the pleated filter 13 . During the unclogging operation, the pleated filter releases a portion of fine dust, which also falls into the refuse collection box 37 .

[72] More precisely, as shown in FIG. 6, the garbage collection box 37 is arranged in two parts, having:

[73] Main compartment 31 for receiving waste from primary separation arriving through conduit 8,

[74] Auxiliary compartment 32 which receives fine waste and dust from the secondary separation and fine filter after the unclogging operation,

[75] Rigid link 33, which connects the two compartments to each other,

[76] A handle 34 which allows the recovery bin 37 to be operated by the user.

[77] The main and auxiliary compartments are preferably chosen to be generally parallelepiped in shape or cylindrical and preferably adapted to fully cooperate with the different components of the vacuum cleaner supported by the base 1 .

[78] More precisely, the volume of the main compartment 31 is greater than that of the auxiliary compartment 32, which is located in the rear and lower part of the cleaner, in the extension of the duct 8, and is positioned substantially relative to the polluted incoming airflow , the airflow is sent in from the receiving port 5 .

[79] The auxiliary compartment 32 is positioned below and substantially perpendicular to the secondary separation chamber, below the filter assembly 9 .

[80] The height of the auxiliary compartment is limited so that the compactness of the cyclonic cleaner is not compromised and the height of the cleaner is not excessive.

[81] Advantageously, as shown in FIG. 6 , the upper parts of the two compartments have cutouts, making it easy to engage the recovery box in the receptacle 7 of the vacuum cleaner. The cut-out is carried out along a plane inclined towards the front of the vacuum cleaner.

[82] This top shape of the litter box facilitates its insertion into the receptacle 7, the compartment 32 serving as a reference point for inserting the litter box 37 into its receptacle. Therefore, the overall shape of the recovery box is designed to fit optimally in the receptacle 7 .

[83] Advantageously, according to the invention, the refuse collection box 37 has at least one gripping device allowing handling of said refuse collection box for maintenance purposes.

[84] Preferably, the holding means is a handle 34 mounted vertically at the rear of the case, substantially centrally and at half-height of the outer surface of the main compartment 31, as shown in FIG. 6 .

The main implementation variant of the proposed embodiment consists in making the filter mobile, the mechanical actuation element being thus fixed. The transmission of motion between the motorized reducer and the filter is obtained, for example, by a gear train assembly (assemblage d'engrenage), which will be described below.

[86] Depending on the position of the motor on the vacuum cleaner, and thus on the orientation and position of the gas discharge, the internal configuration of the filter assembly - which can create different flow patterns for the air and the use of tubular or flat filters - other considerations may also be made. transform.

[87] Figures 7 to 13 show a further embodiment of the invention, wherein, with respect to the embodiment shown in Figures 1 to 6, the main difference concerns the tubular pleated filter 130, which on the one hand is positioned horizontally In the chamber 120 of the separating device 90 , on the other hand, is movable with respect to a fixed mechanical actuation element.

[88] In particular, FIG. 7 shows an exploded view of the separating device 90 and the motor, and the main device for separating the garbage is as described above. However, the primary filter 170 preferably has two arches 172 that are diametrically opposed to limit the bouncing of the tubular filter in the chamber 120 . The two arches bear on recesses 152 arranged on the main body 150 .

[89] According to this embodiment, the garbage recovery compartment 310 separated by the main device is detachably installed in the separation device through the cooperation between the positioning pin and the hook claw 312 from the box and the corresponding receiving seat 92 on the main body 150 The upper part of 90. This compartment is identical to that described in patent application EP1535562.

[90] The secondary filtration is performed by a pleated filter 130, which is thus arranged horizontally in the chamber 120. The discharge of air takes place through an opening 158 arranged on one of the vertical faces of the main body 150 . Thus, the outlet duct 110 conveys filtered air towards the motor 4 which is also arranged horizontally.

[91] Therefore, the unclogged fine dust from the pleated filter 130 is collected by a detachable compartment 320 independent of the compartment 310, which closes the lower part of the main body 150, as shown in FIG. 8 is a partially exploded view of the separation device 90 .

[92] This figure also shows the motorized retarder 100 and a portion of the unjamming mechanism. The motorized reducer 100 is arranged on the main body 150 via the box 104 , opposite the air outlet 158 .

[93] As shown in Figures 8 and 9, the drive mechanism of the filter 130 has two gears 106, 108, one of the gears, here the gear 106, is connected to the filter 130, the axis of which is related to the rotation of the filter 130 Axis coincides. The other gear 108 meshes with the previous gear and is driven to rotate by the drive shaft 102 of the motor reducer 100 .

[94] Gear 108 is sized larger than gear 106 in order to reduce the rotational speed of the filter relative to the speed of shaft 102 of the motorized reducer. Depending on the characteristics of the motorized reducer used, and depending on the desired speed, the number of gears can be higher.

[95] As shown in FIG. Accordingly, the body 150 has a perforated portion 153 that allows a mechanical connection between the gears 106 and 108 . Advantageously, the tightness of the box 104 on the body 150 is designed.

[96] The gear 108 is connected to a plate 132 which, together with another plate 134, constitutes the mechanical support of the filtering envelope 136 of the pleated filter 130.

[97] The unclogging means also includes a cleaning assembly 140 of the pleated filter 130 having six mechanically actuated elements of the pleats of the filter 130 .

[98] The assembly 140 is shown in detail in FIGS. 10 and 11 . Thus, the cleaning assembly comprises curved finger-shaped actuating elements 146 , 148 connected to a central shaft 143 . One of the ends of the shaft has a cylindrical sleeve 144 , while the other end includes, inter alia, a retaining pin 142 .

[99] According to the proposed embodiment, six mechanical actuation elements are arranged inside the filter, in contact with the walls of said filter, said six mechanical actuation elements comprising two sets of three fingers Fingers arranged at two heights along the length of the filter, each set of fingers distributed angularly around axis 143 .

[100] In addition, the ends of each finger 146, 148 each have portions 1460 and 1480 that bulge radially outwardly. Advantageously, the fingers 146 are not strictly located on the extension plane of the fingers 148 . FIG. 11 shows the projection according to the axis 143 shown in FIG. 10 , with the two sets of fingers offset by an angle α, which according to the proposed embodiment is about 30°.

[101] FIG. 12 is a top view of filter assembly 90 without cover 6, filter 170, and tank 310. FIG. 13 is an enlarged view of a detail shown in FIG. 12 .

[102] Thus, the cleaning assembly 140 is held fixed on the main body 150, inter alia, by holding pins 142 arranged at the bottom 156 of the groove 154, these components also being shown in FIGS. 7 and 8 . The end 144 of the shaft 143 is arranged in the opening 135 of the plate 134 .

[103] Thus, according to this embodiment, the motorized reducer drives the tubular filter 130 in rotation about the fixed axis 143 of the cleaning assembly 140.

[104] During work, the passing path of the air is the same as the aforementioned passing path. The raised portions 1460 and 1480 of the fingers 146, 148 engage the pleats of the cuff 136 of the rotating pleated filter during the unclog operation. As a result, a portion of the dust filtered by the filter is released, falling into the compartment 320 .

[105] In the case of a tubular filter arranged horizontally, ie its axis of symmetry is horizontal, it is in fact of interest to rotate the filter relative to the actuating element. In fact, the opposite is not possible to unblock the upper pleats with good efficiency, since the dust suspended in the air will be re-deposited on substantially the same pleats under the action of gravity.

[106] Therefore, preferably, the fingers are not in a vertical position towards the upper part of the chamber 120. FIG. 11 shows the angular positioning of cleaning assembly 140 in chamber 120 with good results.

[107] Figures 14 to 16 show an embodiment in which the waste entry duct 405 in the main separation chamber 408 closed by the cover 406 is substantially horizontal. The dustbin 410 is more consistent with the example shown for the first embodiment of the invention, having a vertical grip handle 412 and a dual waste receptacle consisting of a compartment 414 and a compartment 416, the compartment Compartment 414 is used for waste separated by the main separation device and the compartment 416 is used for waste from clearing clogs. Waste is sent to compartments 414, 416 through conduits 415, 417 mounted on bin 410, respectively.

[108] Furthermore, in order to facilitate the emptying of the tank, the compartments 414, 416 are detachably mounted by means of hinges 418, and latches 419 allow the sealed connection of the compartments to the ducts 415, 417 of the tank to be maintained by seals.

[109] Like FIG. 9, FIG. 15 is an exploded view of the secondary filter 430 and unclogging means located below the separation chamber.

[110] Thus, a corrugated envelope 436 is held between two plates 432, 434, each fitted with an "O"-ring seal, such as seal 435. The device also includes a gear train with a large-sized gear 437 connected to a plate 432 and meshing with a gear 438 whose shaft is connected to a shaft 452 of a motorized reducer 450 . As in the above case, the wiper blade 440 is fixed, around which the cylinder rotates.

[111] Wiper blade 440 is shown in detail in FIG. 16 . It has a holding pin 442 and a shaft 443 on which two mechanical actuation elements 444 , 446 of the bellows 436 are fitted.

[112] Advantageously, the ends of the mechanical actuating elements 444, 446 each have a raised portion 445, 447 in the shape of a small cylinder for gentle interaction with the pleated envelope so that during the unblocking operation, Do as little damage as possible to the surface.

[113] Advantageously, these cylinders 445, 447 are covered with a lubricating material, or a material with a very low coefficient of friction, such as polytetrafluoroethylene.

[114] Preferably, the mechanical actuation element is directed downwards to more effectively clear the blockage. Figure 15 shows these components facing upwards for clarity only.

[115] According to the embodiment shown, the wiper blade can either be embedded in the filter (eg glued), or it can be detached from the filter and assembled by a reversible clamping connection.

[116] In other embodiments, the unclog device may be positioned in the secondary filter chamber, external to the filter assembly.

[117] For example, with respect to the different configurations of the aforementioned vacuum cleaners, it can be designed that the unclogging device is arranged outside and supported on the pleated filter, so that the mechanical actuating element is supported by the ring gear, which The diameter of the pleated filter is larger than that of the pleated filter, so that the filter can be mechanically shaken from the outside to change the direction of air flow from the inside of the filter to the outside.

[118] Another variant that can be considered consists in changing the air passage path so that the polluted air flow has to pass from bottom to top through a flat secondary filter, which is preferably positioned on an inclined support, A mechanical actuation element presses the filter through the air discharge surface to facilitate scraping of blockages in accordance with straight or reciprocating relative motion between the actuation element and the filter surface.

[119] In all embodiments, it is arranged that, under the action of the device according to the invention, the dust from clearing the blockage is recovered under the action of gravity in the lower part of the vacuum cleaner into the compartment provided for this purpose, so that The above compartments are sealed to avoid pressure loss when the vacuum cleaner is in operation.

[120] In all embodiments, it is arranged that the action of the unclogging means does not continue while the vacuum cleaner is in operation. In fact, the unclogging device does not have to work continuously, because on the one hand the filter clogging is slow and on the other hand the friction to the material causes wear.

[121] Preferably, according to the invention, the motorized retarder operates intermittently.

[122] In conducting a vacuum cleaner feasibility study, it was found that it was best to have the unclogging device and the motorized retarder work at the end of each use of the vacuum cleaner. Preferably, according to the invention, a motorized retarder is used each time the vacuum cleaner is deactivated.

[123] Advantageously, a waiting period of one or more seconds after the power module stops before using the motorized reducer makes the efficiency of unclogging less disturbed by the negative pressure generated by the operation of the power module.

[124] In order to discontinuously carry out the cleaning of the secondary filter, it is also possible to consider controlling the delay work of the motor reducer.

[125] In order to shake the filter and drop the dust accumulated on its surface, it is not necessary, according to the considered embodiment, to make several revolutions of the mechanical actuation element or the filter, but only a few revolutions, in fact, the motorized reducer Only works for a few seconds.

[126] Various embodiments of the invention have been proposed for the transmission between the motorized speed reducer and the rotating member, and various embodiments other than those described above can also be considered.

[127] In the different configurations considered, the filter can be flat or tubular, constructed of different materials, and the flow of air in the filter assembly designed in a different way, without going beyond the scope of the invention.

[128] Obviously, the invention is not limited to the embodiments described and shown as examples, but also includes all technical equivalents and combinations thereof.
