Field of the invention

The invention relates to a combination of a small vacuum cleaner comprising a first Staubabscheideeinrichtung with a first dust collector, a fan for generating a suction air flow through the first Staubabscheideeinrichtung and an electric motor for driving the fan, and a vacuum cleaner housing. Further, the invention relates to a small suction device comprising a first Staubabscheideeinrichtung with a first dust collector, a blower for generating a suction air flow through the first Staubabscheideeinrichtung and an electric motor for driving the blower, wherein the small suction device is designed for connection to a vacuum cleaner housing, and a vacuum cleaner housing to Connection to a small vacuum cleaner comprising a first Staubabscheideeinrichtung with a first dust collector.

Background of the invention

Vacuum cleaners are known in different designs. In particular, hand-held vacuum cleaners are known which, due to their compact dimensions and low weight, are suitable for "hands-free" use and which are also referred to as small-sized vacuum cleaners Such small-suction devices can be designed, for example, as table vacuum cleaners ("crumb suckers"). These usually have a moderate suction power and filtering. Furthermore, handheld vacuum cleaners are known, which are operated substantially in a vertical position and are placed, for example, with a floor nozzle on a floor to be cleaned. Since these usually have a rod or a handle for extending a handle, with which the vacuum cleaner is guided, these are also referred to as "Stielsauger." Furthermore, other designs are known, such as vacuum cleaner, which are provided with runners or rollers and Such vacuum cleaners generally have better suction properties and more effective air filtration than the above-mentioned small suction cups To connect small suction with a carrier to use the unit of small suction and carrier, for example, as a handle vacuum. Furthermore, it is known to remove a dust collector from a vacuum cleaner to emptying it.

According to US 2003/01341441 A1, a dust cup arrangement of a vacuum cleaner to be operated vertically, which contains a removable filter arrangement and which defines a cyclically acting air flow chamber, can be removed laterally from the housing of the vacuum cleaner. The vacuum cleaner can only be used in one operating mode.

From JP 106 46 13 A it is known to set up a battery-operated hand-held vacuum cleaner on a holding body, which has a mains-powered fan. When the small vacuum cleaner is used alone, the battery operated fan of the small vacuum cleaner generates a suction air flow through a suction head and a dust collecting chamber of the small vacuum cleaner having a filter for collecting the dust sucked with the suction air flow. When the small vacuum cleaner is operated together with the holding body, the mains-operated fan of the holding body generates a suction air flow through the suction head and the dust collecting chamber of the small suction device and through an opening of the dust collecting chamber and an air guide tube arranged in the holding body. As a result, the dust collection chamber of the small vacuum cleaner can be used in both modes. An improvement of the filter performance in the operation of the small suction device as a unit with the holding body is not achieved thereby.

An improvement in the filter performance in the operation of the small suction device as a unit with a housing with which the small suction device can be connected, could be achieved by the use of a further dust collector associated with the housing. Here, however, the problem arises that an emptying of two dust collector is associated with additional effort.

US 201 1/0289719 A1 discloses a pedestal vacuum cleaner which is operated by a removable from the back of the pedestal vacuum cleaner hand vacuum. The means for retaining and collecting the dust are also arranged in the hand vacuum cleaner. A similar pedestal vacuum cleaner is also known from US 2008/0040883 A1, but here the hand vacuum cleaner can be removed on the front of the pedestal vacuum cleaner. Finally, JP 2008178614 A discloses a stick vacuum cleaner, from which a blower and a dust collecting unit can be removed. Furthermore, in the foot of Stielstaubsaugers another dust collection device is provided, which can be operated without the removable blower; In this case, it is supplied by the rotational movement of a rotary brush dust. The two dust collectors are located at different points of the pedestal vacuum cleaner.

The problem underlying the invention

It is an object of the present invention to provide an improved combination of a small vacuum cleaner and a connectable with this vacuum cleaner housing and a corresponding small vacuum cleaner and a vacuum cleaner housing, with improved filter performance in the operation of the small vacuum unit is made possible with the vacuum cleaner housing, without a significant additional handling effort when removing the separated dust is necessary.

Inventive solution

The reference numbers in all claims have no limiting effect, but are only intended to improve their readability.

The solution of the problem is achieved by a combination with the features of claim 1, a small vacuum cleaner with the features of claim 9 and a vacuum cleaner housing with the features of claim 10.

In a combination according to the invention of a small vacuum cleaner with a vacuum cleaner housing, the small vacuum cleaner comprises a first Staubabscheideeinrichtung with a first dust collector, a fan for generating a suction air flow through the first Staubabscheideeinrichtung and an electric motor for driving the fan. The Staubabscheideeinrichtung may for example comprise an exchangeable filter bag, one or more filters and / or one or more centrifugal or cyclone separator, wherein the first dust collector may be, for example, a dust collection chamber of a centrifugal separator or a filter. The fan can be driven by an electric motor, which can be designed for battery and / or mains operation. Especially For example, the fan and the electric motor driving this can be designed as a motor / fan unit. The blower is arranged for generating a suction air flow through the first Staubabscheideeinrichtung for separating particles contained in the suction air flow, in particular for separating with the suction air flow from a surface to be cleaned dirt and dust, wherein the deposited particles collected in the first dust collector or be withheld. The small vacuum cleaner can be operated separately as a hand-held vacuum cleaner, ie in solo operation, and has the necessary components or functional devices.

According to the invention, the small vacuum cleaner can be inserted into the vacuum cleaner housing in such a way that it is in a state connected to or inserted into the vacuum cleaner housing, i. as a unit with the vacuum cleaner housing, also as a vacuum cleaner is operable, wherein at least a portion of the separated dust is collected in a second dust collector. The second dust collector is assigned in particular to the vacuum cleaner housing. It may be possible to use the small dust collector associated with the first Staubabscheideeinrichtung even when operating the small vacuum cleaner as a unit with the vacuum cleaner housing, with a portion of the separated dust is retained in the first dust collector. However, it can also be provided that, when operating as a unit with the vacuum cleaner housing, the absorbed dust is collected alone in the second dust collector. The vacuum cleaner housing may further comprise the necessary for operation as a stem vacuum components that go beyond the necessary for solo operation of the small sucker devices or functional devices, such as a handle with a Stielsaugerhandgriff or a connection for a stem or a Stielsaugerhandgriff. The small vacuum cleaner is thus not only in solo operation, but in a further operating mode, such as a teat, operable.

Further according to the invention, the first and the second dust collector as a unit, such as a dust box, can be removed from the vacuum cleaner housing. The dust box which can be removed as a unit can also comprise further components and in particular further dust collectors and / or the first and / or further dust separation devices. For this purpose, in particular the first dust collector from the small vacuum cleaner and the second dust collector from the vacuum cleaner housing are separable and connected to each other for joint removal or connectable. When removing the first and second dust collector, the small vacuum cleaner remains in the vacuum cleaner housing. The vacuum cleaner housing may, for example, have an opening through which the unit, which comprises the first and the second dust collector, can be removed. Accordingly, the first and the second dust collector can be used as a unit again in the vacuum cleaner housing and in the small vacuum cleaner.

By virtue of the fact that the small vacuum cleaner can be inserted into the vacuum cleaner housing to form a unit that can be operated as a vacuum cleaner with a second dust collector, and that the first and second dust collectors can be removed as a unit from the vacuum cleaner housing, it is possible to use both the first and the first dust collector Also remove the second dust collector to empty it. Furthermore, it is made possible by providing the second dust collector in the vacuum cleaner housing to achieve a relation to the solo operation of the small suction filter performance increased.

Advantageous embodiments and developments, which can be used individually or in combination with each other, are the subject of the dependent claims.

According to a preferred embodiment of the invention, the second dust collector is associated with a second Staubabscheideeinrichtung, which in turn is associated with the vacuum cleaner housing. This makes it possible, when operating the small vacuum cleaner as a unit with the vacuum cleaner housing to use another or another Staubabscheideeinrichtung and thereby improve the filter performance compared to the solo operation of the small vacuum cleaner on.

Furthermore, it is preferred that the small suction device with respect to a longitudinal axis of the vacuum cleaner housing in the axial direction is inserted into the vacuum cleaner housing and that the first and the second dust collector can be removed as a unit transverse to the longitudinal axis. The longitudinal axis is defined in particular by a front end with a suction section, such as a spigot or a suction head, and a rear end, which carries about a handle with a Stielsaugerhandgriff. Preferably, the small suction can be used from a rear end of the vacuum cleaner housing forth in the axial direction and removed by a movement in the reverse direction again. As a result, a particularly simple handling when inserting and removing the small suction device and when removing and inserting the unit, which includes the first and the second dust collector allows.

Preferably, the first dust collector is designed as a filter. In particular, the first dust collector may be formed as a filter for retaining medium-fine dust, which usually optimal for the solo operation of the small vacuum cleaner.

As a result, an optimal and economical operation is possible for the solo operation of the small suction with respect to the filter performance.

According to a preferred embodiment of the invention, the second dust collector is designed as a dust cup of a Wirbelrohrabscheiders. The Wirbelrohrabscheider may be part of the vacuum cleaner housing or formed when inserting the small sucker in the vacuum cleaner housing. Characterized in that the second dust collector is designed as a dust cup of a Wirbelrohrabscheiders, a particularly effective operation of the small vacuum is made possible as a unit with the vacuum cleaner housing with a particularly high filtration performance.

In a particularly advantageous manner, the second dust collector is designed as a dust cup of a Wirbelrohrabscheiders and the first dust collector as inserted into a dip tube of the Wirbelrohrabscheiders filter foam cylinder. In this way it can be achieved that the suction air flow flows through the Wirbelrohrabscheider and at the outlet of the Wirbelrohrabscheiders the filter foam cylinder. As a result, a particularly high filter performance can be achieved in a simple manner.

In a further advantageous manner, it can be provided that a further dust collector can be removed together with the first and the second dust collector. Such a further dust collector may for example be a coarse dirt separator in a suction head of the small suction device. This can also be emptied after separation from the small vacuum cleaner and removal from the vacuum cleaner housing. As a result, the handling is further simplified.

According to a particularly preferred embodiment, a lint filter is removable together with the first and the second dust collector. The lint filter retains lint sucked with the suction air flow. The lint filter may for example be associated with the vacuum cleaner housing, be tubular and surround the filter foam cylinder in the inserted state of the small vacuum cleaner. Also in this way the handling can be simplified.

In a particularly preferred manner, all dust-collecting components of the small vacuum cleaner and the vacuum cleaner housing, in particular all dust containers and filters, if necessary, except for blow-off or fine-dust filters, can be removed together. In particular, all dust-collecting components can be accommodated in the dust box. Thus, all components that need to be regularly emptied or cleaned, accessible in a particularly simple manner.

The invention further relates to a small vacuum cleaner comprising a first Staubabscheideeinrichtung with a first dust collector, a fan for generating a suction air flow through the first Staubabscheideeinrichtung and an electric motor for driving the blower, wherein the small suction device is designed for connection to a vacuum cleaner housing. According to the invention, the small suction device has a first, inlet-side seal and a second, blower-side seal for sealing an air passage, in particular axially directed, of the suction air flow between the first dust-collecting device and the blower, which is arranged in a direction transverse to the airway, i. in particular transversely to a longitudinal axis of the small sucker, standing direction separable from each other and can be connected to each other again. The small suction device is preferably designed as described above.

In particular, a small suction device according to the invention has a cylindrical or approximately cylindrical basic body. As a result, a particularly simple and stable construction of the small suction is possible.

Detailed description based on an embodiment

In the following description of a preferred embodiment of the present invention, like reference characters designate like or similar components. For clarity, not all figures are shown in all figures. In Fig. 1, an embodiment of a vacuum cleaner according to the invention, which is formed from a vacuum cleaner housing and a small suction used in this, shown in a partially sectioned longitudinal section. The small vacuum cleaner 1 has a substantially cylindrical shape. At a front end of the small suction device 1, a suction head 2 is arranged. A middle section of the small suction device 1 comprises a dust separator 10 and a motor / blower unit 20. At the rear end of the small suction device 1 is a handle 31. The motor / blower unit 20 generates a suction air flow passing through the suction head 2 in FIG the Staubabscheideeinrichtung 10 passes. In the area of the motor / blower unit 20, the sucked air is blown out again.

For receiving the suction air flow in the solo operation of the small suction device 1, a suction mouth 3 of the suction head 2 is provided. Through an air duct 4, the air flow to a manifold 5, where it is deflected in the position in the solo mode down. Another, rugged deflection at the lower end of the manifold 5 causes coarse particles are thrown into the dirt depot 6 located underneath. The bow rib 7 below the manifold 5 prevents a larger amount of the deposited material from being entrained by the air flow again. In this way, a coarse dirt separation can be realized in a small space.

Thereafter, the thus pre-cleaned air flows through a filter foam cylinder 1 1, which may for example have a thickness of about 3 mm and is supported by a tubular window grille 12. From the interior 13 of the filter foam cylinder 1 1, the air is sucked out to the fan. The tube 14, which surrounds the filter foam cylinder 12, has inlet windows 15, which are closed by a locking sleeve 16 which can be displaced in the longitudinal direction of the small suction device 1. The closure sleeve 16 is biased by the force of a relatively soft spring 17 to the front end of the small sucker 1 against a stop, so that when using the small sucker as a hand-held sucker, the inlet window 15 are closed. Further, a sealing seal, not shown, between the closure sleeve 16 and tube 14 may be provided for sealing the inlet window 15. Between the filter foam cylinder 1 1 and pipe 14, an annular gap may be provided to allow a more uniform flow through the filter foam cylinder 1 1 through the dirt-laden air; This also contribute to the inlet window 15, the separate operation of the small sucker. 1 are closed by the closure sleeve 16, but still allow to some extent an axial flow of air along the outer wall of the filter foam cylinder 11.

The blower with the fan 21 and the nozzle 22 conveys the sucked air through arranged in a perforated screen 23 exhaust openings 24 to the outside. The fan 21 is driven by the electric motor 25, which is powered by non-detailed batteries, such as lithium-ion batteries. The motor 25 can be controlled by a switch, not shown, or via a control electronics, also not shown.

The handle 31 is connected to locking cam 33, which cooperate with detent springs 34, each carrying a locking element 35, such that in the position of the handle 31 shown in FIG. 1, a radial movement of the detent springs 34 is prevented inwardly. Preferably, two detent springs 34 are arranged opposite each other.

The aforementioned components are associated with the small vacuum cleaner 1.

The vacuum cleaner housing 40 has, according to FIG. 1 at its front end to an intake manifold 42 to which, for example, a suction nozzle or a floor brush is connected. The incoming through the intake manifold 42 suction air flow is divided into two partial air streams, each guided by air ducts 44 to a rear portion of a Staubabscheideabschnitts 45, where they are deflected by deflection 46 in the tangential direction and guided inwards. It may also be sufficient for a single air duct, which has a sufficient cross-section. In the dust collecting section 45, the deflecting regions 46 of the air ducts 44 open into air supply openings 53 of a pipe 54, which encloses a dust separation chamber 55 and a dust collecting chamber 56. The Staubabscheideraum 55 and the dust collection chamber 56 are separated by a Abscheiderip 57, which leaves a gap to the tube 54. The fenestrated sleeve 18, which, when the small suction device is inserted into the vacuum cleaner housing 40, surrounds the tube 14, carries a tubular lint filter, which may for example have a mesh size of about 1, 5 mm.

In a drive section 47 of the vacuum cleaner housing 40, not shown in Fig. 1 exhaust openings are arranged with a blow-out, for example a flat filter fleece, a lamellar filter, in particular a HEPA filter, or even a filter formed by filter foam, are provided. The exhaust filter can serve as a fine dust filter or be designed as a coarse filter for noise reduction. The exhaust openings are sufficiently large, so that the exhaust filter does not produce a significant flow resistance. It is also possible to provide a plurality of exhaust and / or exhaust filter elements arranged side by side and / or in the air stream one behind the other. At the rear end of the vacuum cleaner housing 40 is a handle port 49 for receiving a rod which carries a handle for use of the vacuum cleaner as a teat suction (not shown), is arranged. The vacuum cleaner housing 40 is open at the rear end to introduce the small suction device 1 in the axial direction from behind into the enveloping body.

In the position shown in FIG. 1, the small suction device 1 is inserted far enough from the rear end of the vacuum cleaner housing 40 that the suction mouth 3 rests against a foam seal 60 and is thus closed. The displaceable closure sleeve 16 is displaced in the axial direction to the rear by an annular edge 61 of the sleeve 18 against the force of the spring 17, which is compressed in the illustration of FIG. 1. As a result, the inlet window 15 of the tube 14 are released, through which the suction air flow into the filter foam cylinder 1 1 can flow. The air flow is conveyed by the fan 21 through the exhaust ports 24 of the small suction device 1 and through the exhaust ports of the vacuum cleaner housing 40 to the outside. In the axial direction in front of and behind the exhaust openings 24 are each formed as circumferential sealing lips 62 sliding seals formed within the vacuum cleaner housing 40 which seal the air path between the exhaust ports 24 of the small sucker 1 and corresponding exhaust openings of the vacuum cleaner housing 40, but a hakfreies and low-friction insertion into the and Allow removal of the small sucker 1 from the vacuum cleaner housing 40. The latching elements 35 abut against the latching projections 36 and thereby hold the small suction device 1 in a position suitable for the interaction of the small suction device 1 with the vacuum cleaner housing 40 as a suction device, possibly against an axial force exerted by the foam seal 60 and the spring 17. Furthermore, the small suction device 1 is thereby secured against unintentional removal from the vacuum cleaner housing 40.

As shown in Fig. 1, a further handle 32 is provided, which is connected to the dust cup 59 formed by the tube 54 and the bottom 58 and by means of which the dust cup 59 can be removed laterally from the housing 40 for emptying the dust. Together with the dust cup 59 and the tube 14 with the Filter foam cylinder 1 1 are removed from the housing 40. If the dust cup 59 removed from the housing 40 of the vacuum cleaner 1, the tube 14 can be pulled out with the filter foam cylinder 1 1 in the axial direction of the dust cup to clean the filter foam cylinder 1 1. The dust cup 59 may be reversed or opened to remove the dust accumulated in the dust collecting space 56. Furthermore, the lint filter can be cleaned.

In Fig. 2 is a side view of the vacuum cleaner housing 40 is shown with inserted small suction 1. It can be seen running on the outer wall of Staubabscheideabschnitts 45 air ducts 44 having at its rear end deflection 46, by which the respective partial air flow is gradually deflected from an axial to a tangential direction. Further, in Fig. 2, the intake 42 are shown at the front end of the vacuum cleaner housing 40 and the handle port 49 at the rear end of the vacuum cleaner housing 41 and the exhaust openings 48 of the vacuum cleaner housing 40 in which a blow-out is maintained. Of the small sucker 1, only the handle 31 can be seen in Fig. 2. Along the line C-C, when removing the dust box 63, the seals described in connection with FIG. 6 are separated.

Fig. 3 shows a view of the vacuum cleaner housing 40 with the small suction device 1 inserted therein seen from the rear end. At the rear end of the vacuum cleaner 1, the handle 31 is arranged. It also recognizes the deflection portions 46 of the two air ducts, which are offset by approximately 45 ° to each other on the outer wall of the substantially tubular housing 40 are arranged. The line labeled A-A marks the sectional area of the partial cross-sectional view shown in FIG.

Due to the tangential introduction of the partial air flows into the dust collecting chamber 55 and the vortex generated thereby generated during operation of the vacuum cleaner as a unit from the small vacuum cleaner 1 and the vacuum cleaner housing 40 at least the coarse dirt particles contained in the suction air by the action of centrifugal force on the inner wall of the tube 54 deposited. In the inserted state of the small vacuum cleaner 1, that is, when using the unit of small vacuum cleaner 1 and 40 vacuum cleaner housing as Stielsauger, thus takes place a deposition of coarse dirt according to the principle of a Wirbelrohrabscheiders. From the inner wall of the tube 54, the deposited particles pass by gravity on the barrier rib 57 into the dust collecting space 56 (see Fig. 1); The Wirbelrohrabscheider is thus designed as Senkabscheider. This is a particularly high suction power through the allows multiple air ducts 44, which may have a relatively large cross section, for example about 1800 mm ² . Lint are retained by the lint filter, which covers the windows of the sleeve 18 and is traversed by the air before reaching the filter foam cylinder 1 1, which retains further coarse and medium-fine dust. In particular for filtering fine dust, a blow-out filter is provided in the blow-out openings 48.

In contrast, in the separate use of the small suction device 1, i. such as when used as a hand-held table vacuum cleaner, a pre-separation of coarse dirt within the suction head 2, as has been explained above. For the separation of medium-fine dust of the filter foam cylinder 1 1. A lint filter is not required, for example, when used as a table vacuum usually. As a result, a particularly compact, lightweight and slim design of the small sucker is possible. When used in solo operation and as a stem vacuum thus come in the illustrated embodiment, different airways and at least partially different Staubabscheideeinrichtungen with different

Staubabscheideprinzipien used that allow each optimized for each type of application cleaning the suction air.

In Fig. 4, the small suction device 1 is shown in a partially removed from the vacuum cleaner housing 40 position, the representation of the partially sectioned view of FIG. 1 corresponds. For this purpose, the handle 31 has been pulled out of the position shown in FIG. 1 so far that the locking cams 33 connected to the handle 31 are disengaged from the locking springs 34. The fact that the locking cam 33 no longer lock the detent springs 34, they can dodge inward in the radial direction. If a traction force is subsequently exerted axially in the rearward direction on the handle 31, which can have an axial stop for this purpose, the latching elements 35 are guided past the latching projections 36 via the latching bevels directed backwards, with the latching elements 35 dodging inwards. As a result, the small vacuum cleaner 1 is unlocked. In the position shown in Fig. 4, the small suction device has been moved by further train on the handle 31 in the axial direction further to the rear.

When inserting the small sucker 1 in the vacuum cleaner housing 40, the locking elements 35 in a reverse movement over the flatter forward directed latching bevels past the locking projections 36 and engage behind the locking projections 36 a. By locking cam 33 unlocking is prevented.

In Fig. 5, the laterally removed dust box 63 is shown, which contains the filter foam cylinder 1 1, the tube 14 and the sleeve 18 which carries the lint filter. Furthermore, the dust box 63 includes the dust cup 59 with the tube 54, the bottom 58, wherein in the dust box 63 in particular the dust collecting chamber 56 and the suction head 2 are included with the dirt depot 7. The removable as a unit on the handle 32 dust box 63 thus includes all the dust collector of the small vacuum cleaner 1 and 40 of the vacuum cleaner except for the fine dust filter. Because they can be removed together, a particularly simple handling for emptying or cleaning the dust collector is possible. To clean the lint filter and the filter foam cylinder 1 1, these can be pulled out of the dust cup 59 in the axial direction to the rear.

FIG. 6 shows a view of the vacuum cleaner housing 40 with dust box 63 taken laterally as shown in FIG. 5, as seen from the rear end. In contrast to the illustration of FIG. 3, the seal 64 can be seen, which laterally seals the air path from the interior 13 of the filter foam cylinder to the blower during operation of the vacuum cleaner and also during solo operation of the small suction device 1 with a corresponding blower-side seal. For connecting the seals and for separating by a lateral movement, an arcuate rib 65 is provided which has a groove into which engages the blower-side seal upon insertion of the dust box 63. Furthermore, a bolt may be provided to prevent inadvertent removal of the dust box. The line labeled A-A marks the sectional area of the partially cut view shown in FIG.
