Description

WO 2012/113821 PCT/EP2012/052994 Vacuum cleaner dust container and a vacuum cleaner TECHNICAL FIELD 5 The present application is directed to a vacuum cleaner dust container and a vacuum cleaner having at least one cyclonic dust separation unit coupled to a respective vacuum cleaner dust con tainer intended for collecting dust separated in the dust sepa ration unit. 10 BACKGROUND Cyclone type vacuum cleaners are widely known because of their benefit in bagless dust collection. Bagless or cyclone type vac uum cleaners or respective cyclone dust separating units are 15 known for example from documents EP 1 042 981 Al, EP 1774887 Al, EP 1 688 078 A2, EP 1 952 745 A2 and WO 2011/058365. Cyclone type vacuum cleaners, in particular mentioned in the state of technology documents listed before, still have compara 20 tively complicated dust collecting units, requiring complicated cleaning and emptying of dust collected in respective dust col lecting chambers. As may be realized there is a need for improvements in the area 25 of bagless vacuum cleaners in particular with respect to the dust collecting units. SUMMARY 30 It is one of the objects of the present invention to solve the problems observed with state of technology. In particular, a cyclone type vacuum cleaner and a vacuum clean er dust container shall be provided, which enable convenient use 35 and operability. 1 WO 2012/113821 PCT/EP2012/052994 In addition, an improved solution for emptying of dust from a bagless vacuum cleaner shall be provided, in particular allowing a user quick, easy and convenient removal of dust. 5 These and other objects are solved by the features of claims 1 and 9. Embodiments and variants in particular result from re spective dependent claims. 10 According to claim 1, a vacuum cleaner dust container is provid ed which comprises a base body accommodating a dust collecting chamber adapted to be coupled to a cyclonic dust separation unit of a vacuum cleaner. 15 Coupling the base body, in particular dust collecting chamber, and cyclonic dust separation unit to each other in particular shall mean, that dust separated in the cyclonic dust separation unit can be or will be collected in the dust collecting chamber. Here, a dust outlet opening of the cyclonic dust separation unit 20 may be connected, in particular fluidly connected, with a dust inlet opening of the dust collecting chamber. The vacuum cleaner dust container may be releasably mounted or coupled to the cyclonic dust separation unit. It is preferred, 25 that the vacuum cleaner dust container as such is releasably mounted or coupled to the vacuum cleaner or cleaner body of the vacuum cleaner. Any suitable holding, fastening and/or locking mechanisms may be provided for releasably coupling or mounting at least the vacuum cleaner dust container to the vacuum clean 30 er. The cyclonic dust separation unit may be a part of a first stage cyclonic separation step. Note that a respective vacuum cleaner may comprise further separation steps, in particular second 35 stage cyclonic separation steps. 2 WO 2012/113821 PCT/EP2012/052994 The vacuum cleaner dust container further comprises a lid or cover adapted to close a dust discharge opening of the dust col lecting chamber. The lid or cover may be hingedly and/or 5 slidably connected to the base body of the vacuum cleaner dust container. The vacuum cleaner dust container further comprises an actuating mechanism coupled between the lid and base body and adapted and 10 designed for controlling opening and/or closing movements of the lid. In particular, the actuating mechanism is adapted to allow control of opening and/or closing movements of the lid by manual action of a user. In other words, the actuating mechanism may be implemented such that if a user operates the actuating mecha 15 nism, the lid is moved or shifted from the closed position, in which the discharge opening is tightly closed, to or towards the open position, in which the discharge opening is released for discharging dust from the dust collecting chamber. Operating the actuating mechanism the other way round will result in closing 20 the dust discharge opening in that the lid is moved to the closed position. As can be seen, the actuating mechanism is suitable for effect ing, controlling and/or conducting opening and/or closing opera 25 tions, actions and/or movements of the lid. In particular the actuating mechanism allows a user, in particular by manual ac tion, to fully control the time course and chronological se quence of opening and/or closing the lid. In particular, the ac tuating mechanism enables to control the speed of opening and/or 30 closing the lid, the degree of opening, i.e. releasing, the dust discharge opening and others. As a consequence, removal and dis charge of dust from the dust collecting chamber can be greatly enhanced and simplified. In particular, swirling of dust, which generally occurs during opening and closing actions of the dust 35 collecting chamber, can be greatly reduced. Further, the dust 3 WO 2012/113821 PCT/EP2012/052994 collecting chamber can be emptied without requiring a user to touch dusty parts of the lid. The dust load and pollution in connection with emptying vacuum cleaner dust containers there fore can be greatly reduced. 5 According to an embodiment, a dust inlet opening of the dust collecting chamber is provided at a top side and the discharge opening and lid are provided at the bottom side. Note that the terms "bottom" and "top" shall refer to the ordinary position of 10 use of the vacuum cleaner dust container. With respective de signs, it is of particular advantage to provide the proposed ac tuating mechanism, as lids positioned at the bottom side are comparatively difficult to access, but can be easily handled with an actuating mechanism as proposed herein. 15 As to the dimensions of the dust collecting chamber, it shall be noted that they may be selected according to respective needs. As an example, the dust collecting chamber may have a cylindri cal shape. Here, in particular circular and rectangular axial 20 cross sections may be used. With the embodiment mentioned above, it is of particular ad vantage that the lid is hingedly, in particular rotatably, cou pled to a bottom edge of the dust collecting chamber, in partic 25 ular base body, via at least one hinge-joint. A lid connected via a hinge-joint may be advantageous for the overall process of discharging dust from the dust collecting chamber. It shall how ever be noted, that also sliding lids or covers may be provided, where opening and closing of the discharge opening require slid 30 ing movement of the lid. It shall further be noted, that the lid or cover may comprise multiple, in particular a pair of, lid sections. Respective lid sections may be hingedly attached to the base body and, with the aim of controlling opening/closing, coupled to the actuating mechanism. 35 4 WO 2012/113821 PCT/EP2012/052994 In a further embodiment, the actuating mechanism is hingedly and/or slidably connected or fixed to the lid and is movably, in particular slidably, and/or hingedly connected to the base body. In particular, the actuating mechanism may be rotatably connect 5 ed to the lid, and slidably and rotatably attached to or at an outer wall section of the dust collecting chamber or base body. For sliding attachment, a section, in particular end section, of the actuating mechanism may be coupled to guide rails positioned 10 and running along the base body, in particular an outer wall of the base body. In particular, connecting the actuating mechanism to the base body is effective in avoiding loose parts that may disturb com 15 fortable handling of the vacuum cleaner dust container. In a further embodiment it is provided that the actuating mecha nism comprises a lever mechanism having a lever which is coupled with a first end to the lid and with a remote second end to an 20 outer wall of the base body, in particular an outer wall section of the dust collecting chamber. A section of the lever between the first and second end may be used by an operator as a hold or handle to move the lid between the closed and open configura tions. Levers are advantageous for providing uncomplicated me 25 chanical actuating while securing straightforward operation. It shall however be mentioned, that the actuating mechanism may also comprise a knob or button moveably, in particular slidably, attached or fixed to the base body, and coupled to the lid via 30 connectors or connector bars attached to the lid. Here, move ment, in particular linear movement, of the knob or button may be translated in a rotational movement of the lid, i.e. move ments for opening or closing the lid. 5 WO 2012/113821 PCT/EP2012/052994 In a variant of the lever-based embodiment, it is provided that the lever essentially is L-shaped, i.e. it comprises two angled wings or legs. The legs may be angled by about 90 degrees. Fur ther, the lever may be implemented and mounted such that in the 5 closed position of the lid the lever passes around an edge of the vacuum cleaner dust container, in particular base body. The edge at which the angled lever passes around preferably is the one at which the lid is pivotably coupled to the dust collecting chamber, in particular base body. 10 The term "passing around" used in connection with the position and orientation of the angled lever in the closed configuration shall in particular be understood as follows. In the closed po sition of the lid, the first leg of the lever runs along the 15 outer side of the lid and the second leg of the lever, angled from the first leg, runs along a lateral or outer side of the dust collecting chamber or base body. Using a two-legged lever will result in a configuration in which 20 the free end of the first leg is attached, in particular hingedly attached, to the lid. The free end of the second leg can be movably, in particular slidably, attached to the base body, in particular a lateral or outer wall of the dust collect ing chamber. 25 Using an L-shaped lever passing around an edge has the ad vantage, that the lever may be positioned and aligned close to the base body in the closed configuration. This in turn is fa vorable for space saving designs. 30 In a further embodiment, the actuating mechanism, in particular the lever mechanism, in particular lever, comprises a locking unit. The locking unit may for example be positioned and provid ed on or at the lever. The proposed locking unit is intended and 35 adapted to lock the actuating mechanism, in particular lever, in 6 WO 2012/113821 PCT/EP2012/052994 at least one of an open position and closed position of the lid. Providing respective locking mechanisms has the advantage that unintended opening or closing of the lid can be greatly avoided in the course of utilizing and emptying the dust collecting 5 chamber. The locking unit may for example comprise a snap element or snap fit, in particular hook-type snap fit. It may be provided, that the snap fit can be activated, i.e. lock the lid, in selected 10 opening and closing configurations, such as in fully closed and fully opened configuration. It is also conceivable that the snap fit may be activated at any stage during opening and closing the lid, which would mean that the position of the lid can be fixed at any stage during opening/closing. 15 In a yet further embodiment, the actuating mechanism, in partic ular lever mechanism, is adapted and designed to exert in the closed position of the lid a pressing force on the lid to tight ly close the dust collecting chamber, i.e. a dust discharge 20 opening of the dust collecting chamber. Exerting the proposed pressing force means that the lid can be urged into and towards the fully closed position such that unintended escape of dust at the dust discharge opening essentially can be prevented. 25 A pressing force may for example be generated by spring elements or clamping elements or other devices acting on the lever. In particular, it may be provided that the locking unit is adapted to act on the lever such that in addition to a locking force, pressing force acting on the lid in and towards the closed posi 30 tion is generated. According to claim 9, a vacuum cleaner is provided which com prises at least one cyclonic dust separation unit and a vacuum cleaner dust container according to one of the embodiments and 35 variants described above and further below. 7 WO 2012/113821 PCT/EP2012/052994 With the proposed vacuum cleaner, the dust outlet of the cyclon ic dust separation unit is coupled to a dust inlet of the vacuum cleaner dust container. Using the proposed vacuum cleaner dust 5 container in a vacuum cleaner greatly enhances and simplifies operation. In particular discharging dust from the dust collect ing chamber, i.e. emptying the vacuum cleaner dust container, can be performed in a comparatively easy way. As to further ad vantages and advantageous effects, reference is made to the de 10 scription above and further below. In one embodiment of the vacuum cleaner, it is provided that the vacuum cleaner dust container is arranged and mounted at the front side of the vacuum cleaner. Such an arrangement is advan 15 tageous for providing easy access to the vacuum cleaner dust container, which simplifies emptying of the dust colleting cham ber. DETAILED DESCRIPTION OF EMBODIMENTS 20 Embodiments of the invention will now be described in connection with the annexed figures, in which. Fig. 1 shows a perspective top view of a vacuum cleaner dust container; 25 Fig. 2 shows a side view of the vacuum cleaner dust container; Fig. 3 shows bottom view of the vacuum cleaner dust container; 30 Fig. 4 shows a cross sectional view along line IV-IV in Fig. 3; Fig. 5 shows a perspective side view of the vacuum cleaner dust container; 8 WO 2012/113821 PCT/EP2012/052994 Fig. 6 shows vacuum cleaner comprising the vacuum cleaner dust container and 5 Fig. 7 shows a cross sectional view of the vacuum cleaner. The figures show different views of a vacuum cleaner dust con tainer 1. The vacuum cleaner dust container 1 comprises a base 10 body 2 accommodating a dust collecting chamber 3 (see Fig. 4). The dust collecting chamber 3 is adapted to be coupled to cy clonic dust separation unit 21 of a vacuum cleaner (see Fig. 7). Coupling of the dust collecting chamber 3 to the cyclonic dust 15 separation unit 21 is such that a dust outlet opening 4 (see Fig. 4) of the cyclonic dust separation unit is fluidly connect ed to a dust inlet opening 5 of the dust collection chamber 3. Note that the vacuum cleaner dust container 1 shown in the fig 20 ures comprises a section, in particular end section, of the cy clonic dust separation unit 21. The respective end section is shown in the figures, except Fig. 3, and denoted by reference sign 6. Note that accommodating a section 6 of the cyclonic dust separation unit 21 within the vacuum cleaner dust container 1 or 25 base body 2 is not mandatory. The vacuum cleaner dust container 1 may also be realized without any components of the respective cyclonic dust separation unit 21. The vacuum cleaner dust container 1 further comprises a handle 7 30 easing handling and operation of the vacuum cleaner dust con tainer 1. In particular, removal and reinstallation of the vacu um cleaner dust container 1 in the course of emptying the dust collecting chamber 3 may be greatly simplified by providing such a handle 7. 35 9 WO 2012/113821 PCT/EP2012/052994 The vacuum cleaner dust container 1 further comprises a lid 8. The lid 8 is provided and adapted to close a dust discharge opening 9 of the dust collecting chamber 3, which can be best seen in Fig. 3 and 4. The lid 8 may comprise a gasket and the 5 like, such that a tight, in particular fluid tight and dust tight seal between lid 8 and lower edge of the dust discharge opening 9 can be obtained. The lid 8 is hingedly attached, i.e. coupled to the base body 2 10 via hinge-joints 11. The hinge-joints 11 are provided at a bot tom side of the base body 2, and protrude from an outer face of the base body 2. Note that with respect to the ordinary use position of the vacu 15 um cleaner dust container 1, the lid 8 and dust discharge open ing 9 are positioned at the bottom, and the end section 6 of the cyclonic dust separation unit and the handle 7 are positioned at the top. This in particular means that the dust inlet opening 5 of the dust collecting chamber 3 is provided towards or at the 20 top side and the dust discharge opening 9 and lid 8 are provided at the bottom side. The vacuum cleaner dust container 1 further comprises an actuat ing mechanism 12. As will be described in further detail below, 25 the actuating mechanism 12 is coupled between the lid 8 and the base body 2, and is adapted and designed for controlling opening and/or closing movement of the lid 8. The actuating mechanism 12 comprises an L-shaped, i.e. angled, 30 lever 13. The lever 13 in turn comprises a first leg 14 and a second leg 15. An angle between the first leg 14 and second leg 15 amounts about 90 degrees. The first leg 14 is hingedly connected to the lid 8, so that ro 35 tational movement between the lid 8 and first leg 14 is possi 10 WO 2012/113821 PCT/EP2012/052994 ble. A rotational axis at the interface between lid 8 and first leg 14 is essentially parallel to a rotational axis of the hinge-joint 11. Note that it is not necessary that the first leg 14 is fixedly attached to the lid 8. However, fixing the first 5 leg to the lid 8 may enhance operability of opening and closing actions. The second leg 15 is connected to an outer side of the base body 2. In more detail, the second leg 15 is hingedly and slidably 10 connected to the base body 2. Here, at the outer side of the base body 2 there may be provided sliding rails 16, to which an end section of the second leg 15, distant from the first leg 14, is hingedly and slidably connected to. End stops 17 may be pro vided at the upper ends of the sliding rails 16 restricting the 15 opening movement of the second leg 15 and therefore the lid 8. In the figures, the lid 8 and actuating mechanism 12 are shown in an open configuration of the lid 8. As can easily be derived from the figures, the L-shaped lever 13 will pass around a lower 20 edge 18 of the vacuum cleaner dust container 1 or base body 2 in the closed configuration of the lid 8. Note that the lower edge 18 corresponds to the edge at which the lid 8 is hingedly cou pled to the base body 2 via the hinge-joint 11. 25 Passing around the lower edge 18 in particular means, that the first leg 14 will run essentially parallel to and along a part of the lid 8. Further, the second leg 15 in the closed configu ration will run essentially parallel to and along a respective section of the outer side wall of the base body 2. Note that the 30 lid 8 and/or side wall may comprise recesses adapted to at least partially accommodate therein, in the closed configuration, the first 14 and second leg 15. As can be readily seen from the figures, the actuating mechanism 35 12 provides the possibility for a user to actively control the 11 WO 2012/113821 PCT/EP2012/052994 opening and closing movement of the lid 8. This has the ad vantage, that discharging dust from the dust collecting chamber 3 can be conducted with minimal or reduced whirling or dispers ing of dust. Further, the user advantageously can avoid contact 5 ing or touching dusty parts or faces, which greatly enhances op erational comfort. With respect to Fig. 2, 4 and 5, it can be seen that the actuat ing mechanism 12 comprises a locking unit 19. The locking unit 10 19 in the present case is implemented as a kind of hook. The hook is provided and adapted to lock the lid 8 in its fully opened position. The fully opened position corresponds to the situation in which the second leg 15 abuts the end stops 17. In the alternative, or in addition, the locking unit 19 may be pro 15 vided and adapted to lock the lid 8 in the closed position. In all, unintentional closing of the lid 8 during emptying the dust collecting chamber 3 and unintentional opening of the dust col lecting chamber 3 in ordinary use can be prevented. 20 The actuating mechanism 12, but in particular also the locking unit 19, may be adapted and designed such that in the closed po sition of the lid 8, a pressing force urging the lid 8 towards the closed position is generated. This may help to avoid the es cape of dust at the lid 8 and dust discharge opening 9 inter 25 face. Reference is now made to Fig. 6 and Fig. 7 respectively showing a perspective view of vacuum cleaner 20 and a cross sectional view of the vacuum cleaner 20. The vacuum cleaner 20 comprises a 30 cyclonic dust separation unit 21 and the vacuum cleaner dust container 1 described in connection with Fig. 1 to 5. The cyclonic dust separation unit 21 in the present case is a horizontal type cyclone separator, which means that during ordi 12 WO 2012/113821 PCT/EP2012/052994 nary operation, a main airflow through the cyclone separator is directed horizontally, i.e. parallel to the ground underneath. The vacuum cleaner dust container 1 is arranged and positioned 5 at the front side of the vacuum cleaner 1. In particular, the vacuum cleaner dust container 1 is removably attached to the vacuum cleaner 20 and cyclonic dust separation unit 21 such that the dust collecting chamber 3 can easily be emptied if required. 10 For emptying the dust collecting chamber 3, the vacuum cleaner dust container 1 may be released from the vacuum cleaner 1 and taken away via the handle 7.
