From the US 2007/0119015 A1 a portable suction device and a method for storing a suction hose of the portable suction device are known. The invention is based on the object of optimizing the storage of a suction hose.

This object is achieved in accordance with the invention in the suction head mentioned at the outset in that a fixing element for the securing element is arranged at a height distance from the at least one holding element, or in the method according to claim 14 that the stack of windings has a securing element assigned to the at least one holding element , which runs between the at least one holding element and a fixing point at a height distance from the at least one holding element, is secured with respect to lateral omission.

It is provided that the suction hose can be supported against falling down by the at least one holding element, and that the at least one holding element is arranged and designed such that the suction hose can be wound around the side wall in a plurality of turns.

In the embodiment mentioned, the side wall of a suction head can be used, so to speak, as a winding core in order to store the suction hose in a simple and space-saving manner.

The at least one holding element ensures defined conditions in that the suction hose and, in particular, a set of windings, which is formed by the suction hose being wrapped around the suction head, is supported against falling downwards.

The solution according to the invention can be implemented in a structurally simple manner.

In particular, the at least one holding element is arranged on or in the vicinity of a lower edge of the suction head. For example, a reinforcement area that is present anyway, on which a fixing device is formed for fixing the suction head to a suction cup, can be used to fix the at least one holding element. Furthermore, a large height distance to an upper side is achieved, so that a plurality of turns can be wound around the suction head and the suction hose does not protrude over the top of the suction head when it is wrapped around the suction head with typical lengths of the suction hose. Furthermore, it is possible to achieve a large distance from a surface on which a suction device with the suction head rests. This prevents a sagging suction hose from touching the floor.

It is then favorable if the at least one holding element is arranged on a reinforcement area of the side wall. There the side wall has sufficient structural stability for the fixing of the at least one holding element.

In particular, a fixing device for fixing the nipple head to the nipple container is then arranged on the reinforcement area.

It is favorable if the at least one holding element has an insertion space for the suction hose, which is delimited by a wall that secures the suction hose against falling downwards and in particular is designed so that it secures the suction hose against falling away from the side wall to the outside . In this way, in particular, a first turn (lower turn) of the suction hose can be secured against being removed from the side wall. The lower turn can then in turn form a base for supporting further turns.

In particular, the insert space is designed to accommodate a single turn. A set of turns can then be produced, for example, in which adjacent turns lie on top of one another. As a result, the width of the suction head with the wound suction hose can be minimized, since the corresponding turns can then be positioned in a height direction.

In particular, the insert space is delimited by a concave and, for example, cylindrical surface. This allows the suction hose to be inserted and it is secured against falling outwards as well as downwards. Furthermore, the suction hose is secured against damage by a good contact.

In particular, the at least one holding element is designed in the shape of a hook. As a result, an insert space for a suction hose can be provided in a simple manner.

In one embodiment, the at least one holding element has a concave outer surface. If edges or the like are avoided, then, for example, a securing element can be guided easily and safely on an outside of the at least one holding element.

A securing element for turns of the suction hose is assigned to the at least one holding element. The securing element can, in particular, secure a set of turns and, for example, press it against the side wall.

The securing element is designed in particular as a tensioning element and is preferably flexible and elastic.

It is favorable if the securing element is designed as a loop or comprises a loop. As a result, the securing element or a corresponding part of the securing element can be hooked into a hook in a simple manner, for example. This in turn makes it possible in a simple manner, when the securing element is released, to wind the hose around the suction head and then to secure the corresponding set of turns on the suction head.

A fixing element for the securing element is arranged at a vertical distance from the at least one holding element. The securing element can be fixed on the fixing element. When the securing element is fixed on the fixing element, the securing element runs between the holding element or an area in the vicinity of the holding element to the fixing element. In this way, a set of turns can be secured against falling out to the side and preferably pressed against the side wall of the suction head.

It is favorable if the fixing element is designed as a suspension element for a loop. The fixing of the securing element on the fixing element is thereby achieved in a simple manner.

It is favorable if the fixing element is arranged on or in the vicinity of an upper edge of the side wall or is arranged on an upper side of the suction head. As a result, a large vertical distance can be bridged with the securing element, in order to be able to secure, in particular, a set of turns with several turns. This in turn enables Stack turns on top of each other in order to minimize the increase in width of the suction head even when the suction hose is wound up.

In one embodiment, the fixing element is arranged in such a way that it does not protrude beyond a surface of an upper side of the suction head. For this purpose, it is arranged, for example, on the side wall or arranged on the upper side offset with respect to the remaining surface thereof.

For example, the securing element is designed as a tensioning element and, in particular, is designed to be stretchable and is, for example, a rubber band or comprises one. This makes it possible to secure a set of windings in a simple manner.

The securing element is fixed on the at least one holding element or on the side wall in the vicinity of the at least one holding element and, in particular, is detachably fixed. This allows a set of turns to be secured in a simple manner.

In one embodiment, the at least one holding element is releasably fixed on the side wall. In this way, for example, a holding element can be removed when it is not needed.

In particular, a turbine device and / or a filter device is arranged on the suction head, the turbine device and / or the filter device being arranged in particular in an interior space of the suction head delimited by the side wall.

According to the invention, a suction device is provided which comprises a suction head according to the invention.

In particular, the teat has a teat container on which a suction hose and in particular a spiral hose via a connection point connected or connectable. The suction hose can then be easily wrapped around the suction head and fixed there.

It is advantageous if the at least one holding element is positioned at a vertical distance upward from the connection point. As a result, it can be prevented that, even if the suction hose sags in the area between the connection point and the closest holding element on which it is supported, touching the floor on which the suction device stands.

For example, the at least one holding element is arranged around the side wall at a distance of at most 25% and in particular at most 10% of the length of a turn of the suction hose in relation to the connection point. This prevents the suction hose from sagging too much on the route between the connection point and the closest holding element.

It can be provided, for example, when a plurality of holding elements are present, that at least one first holding element and one second holding element are arranged at least approximately symmetrically with respect to the connection point. In this way, for example, a suction hose can also be wound around the suction head in any desired direction.

According to the invention, it is provided in the aforementioned method for storing a suction hose of a suction device that the stack of windings is laterally omitted via a securing element assigned to the at least one holding element, which runs between the at least one holding element and a fixing point at a height distance from the at least one holding element is secured.

The method according to the invention has the advantages already explained in connection with the suction head according to the invention and the suction cup according to the invention.

Further advantageous embodiments of the method according to the invention have also already been explained in connection with the suction head according to the invention and the suction cup according to the invention.

In particular, the method according to the invention can be carried out with the suction device according to the invention.

An embodiment of a suction cup 10 according to the invention ( Figures 1 and 2 ) is a wet-dry vacuum cleaner. It can also be a pure dry vacuum cleaner or a pure wet vacuum cleaner. The teat 10 comprises a teat container 12, which has a wall 14 and a bottom 16.

An interior space 18 is formed by the wall 14 and the base 16, in which suction material can be received directly or via a bag.

The teat container 12 has a connection point 20 for a suction hose 22. The suction hose 22 is in particular a spiral hose. At the connection point 20, the suction hose 22 is in particular releasably fixed.

The suction device 10 furthermore comprises a suction head 24. The suction head 24 has a side wall 26 and an upper side 28, which is formed, for example, on a cover wall which is connected to the side wall 26. The upper side 28 is formed on the region of the suction head 24 which is at the greatest distance from a horizontal plane (in relation to the direction of gravity g) when the suction device 10 stands on this plane. This cover wall is, for example, connected in one piece to the side wall 26. The upper side 28 is designed to be flat, for example, in order in particular to provide a storage area. It can also be curved, for example. There can also be a continuous transition from side wall 26 to upper side 28.

An interior space 30 is formed on the suction head 24 via the side wall 26 and the upper side 28. The side wall 26 can, for example, have four sides, with adjacent sides being transverse and in particular perpendicular to one another. It can also have a convexly curved, closed wall. A turbine device 32 with a motor device 34 is arranged in the interior 30. Furthermore, the turbine device 32 is preceded by a filter device 36 with one or more dust filters, the filter device 36 being arranged in the interior space 30.

The nipple head 24 can be placed on the nipple container 12 and can be fixed to it via a fixing device 38. To empty the suction container 12 of suction material (which is contained in a bag or The suction head 24 can be removed from the suction container 12 directly in the interior 18).

The fixing device 38 comprises, for example, one or more latching elements 40, via which the teat head 24 can be latched to the teat container 12.

In one embodiment, the side wall 26 has a reinforcement region 44 on or in the vicinity of a lower edge 42, on which the fixing device 38 is formed.

“Below” refers to the direction of gravity g when the suction device 10 is set up on a base above the suction device container 12, for example by means of wheels 46.

One or more holding elements 48 ( Figures 1 to 3 ) arranged. A holding element 48 is fixedly or releasably fixed on the side wall 26. The holding element 48 lies in particular at a vertical distance upwards from the connection point 20.

A holding element 48 is designed, for example, in the shape of a hook. It has an insert space 50 for a turn 53 of the suction hose 22. The insert space 50 is delimited by a wall 52, the wall surface 55 being curved towards the insert space 50 and, in particular, being curved in a concave manner. For example, the wall 52 is designed to be cylindrical at least in a partial area. The wall 52 is designed in such a way that the inserted winding 53 (cf. Figures 2 and 3 ) of the suction hose 22 downwards (in a direction 54 according to FIG Figure 3 ) is supported and against falling out to the side (in a direction 56 according to FIG Figure 3 ) is secured away from the side wall 26. If the vacuum cleaner 10 is set up with the suction container 12 and the wheels 46 on a horizontal base, then corresponds the direction 54 of the direction of gravity and the direction 56 is a direction transverse and in particular perpendicular to the direction 54.

The insertion space 50 is designed, in particular, in such a way that a single turn (the turn 53) can be inserted.

The holding element 48 has a convex surface 58 on its outside. This avoids corners and edges. Furthermore, as will be described in more detail below, a securing element can then also be placed on this outside.

A width of the holding element 48 (and thus of the insertion space 50) and in a direction transverse to the directions 54 and 56 is in particular at least 3 cm.

As in FIG Figure 2 indicated, wrap the suction hose 22 around the suction head 24 in one or more turns. To a certain extent, the suction head 24 provides a winding core. The holding element 48 supports the windings downwards and prevents them from falling down in the direction 54. The lowermost turn 53 is secured against falling out to the side in the direction 56.

The holding element 48 is preferably arranged at a distance from the connection point 20 (based on the course of the suction hose 22), which is at most 25% and in particular at most 10% of the length of a (complete) turn of the suction hose around the suction head 24. As a result, excessive sagging in the area between the connection point 20 and the closest holding element 48 can be prevented.

There can be one holding element 48 or a plurality of holding elements. In Figure 1 and 2 further holding elements 60a and 60b are indicated.

If a plurality of holding elements are provided, then in particular a first holding element (the holding element 48) and a second holding element (the holding element 60a) are arranged symmetrically with respect to the connection point 20. This makes it easy to wind up.

The holding element or elements 48, 60a, 60b are arranged on or in the vicinity of the lower edge 42 of the suction head 24 that one turn and in particular a plurality of turns can be wound around the suction head 24 as a winding core. The lower turn 53 is supported directly on the holding element 48. An adjacent overlying turn 62 ( Figure 3 ) is supported on the lower turn 53. A turn 64 that is adjacent to the turn 62, in turn, is supported on the turn 62. As a result, there is a set of turns 66 which is supported on the holding element or elements 48.

The holding element or elements 48 are arranged in such a way that, given the typical length of the suction hose 22, the winding package 66 does not protrude beyond the top side 28, that is to say that the side wall 26 provides a contact surface for the winding package 66.

A securing element 68 is assigned to the holding element 48. The securing element is fixed to the holding element 48 via a fixing device 70 and, in particular, is releasably fixed. For example, the securing element 68 itself is fixed on the fixing device 70 and the fixing device 70 is in turn fixed on the holding element 48, in particular in the area of the convex surface 58.

It is also possible that the securing element 68 is not fixed directly to the holding element 48 via its fixing device 70, but rather to the side wall 26 in the vicinity of the holding element 48.

If a securing element 68 has to be exchanged, an operator can do this in a simple manner by releasing the fixing device 70 and exchanging the securing element 68.

A fixing element 72 is assigned to the securing element 68 and is seated on the suction head 24 at a vertical distance from the holding element 48. For example, such a fixing element 72 is formed in one piece on the side wall 26.

A fixing element 72 is designed, for example, as a suspension element in which the securing element 68 can be suspended. For example, the fixing element 72 is designed as a type of hook into which a loop 74 of the securing element 68 can be suspended.

In one embodiment, the securing element 68 itself is designed as a loop 74 ( Figure 4 ). As a result, the securing element 68 can, as it were, be suspended as a whole in the fixing element 72.

In an alternative embodiment, a securing element 76 is provided which, for example, has a ring 78 which forms a loop 80. The ring 78 is seated on a part 82 of the securing element 76, on which in turn the fixing device 70 is seated. The ring 78 is made of a metallic material, for example. The securing element 76 can be suspended from a fixing element 72 via the loop 80 of the ring 78.

The securing element 68 is designed to be stretchable, in particular as an elastic tensioning element. In the case of a securing element 76, in particular the part 82 is designed to be stretchable. In the Figures 4 and 5 this is indicated by the double arrow with the reference numerals 84a or 84b. As a result of the elastic design, the winding set 66 can be pressed against the side wall 26 when the securing element 68 or 76 is fixed to the associated fixing element 72.

A fixing element 72 is arranged in particular on or in the vicinity of an upper edge (an edge on the upper side 28) of the side wall 26. A fixing element 72 can also be arranged directly on the upper side 28.

In one exemplary embodiment (not shown in the drawings), the fixing element 72 is arranged and designed in such a way that it does not protrude beyond a surface of the upper side 28.

The suction head 24 according to the invention or the Sauer 10 according to the invention functions as follows with regard to "stowing" the suction hose 22:

To wind the suction hose 22 around the suction head 24, the securing element (s) 68 are detached from the associated fixing element (s) 72. The lower turn 53 of the suction hose 22 is inserted into the holding element or elements 48, the suction hose 22 being wrapped around the suction head 24 (around its side wall 26). The turn 62 is then placed on the lower turn 53, the turn 64 on the turn 62, and so on. As a result, the winding set 66 is produced. This set of turns 66 is supported on the holding element 48 and is thereby secured against falling down in the direction 54. The lower turn 53 is secured against falling out in the direction 56.

The securing element 68 is then suspended from the fixing element 72. As a result, the winding set 66 as a whole is also secured against falling out in the direction 56. With an elastic design of the securing element 68, the winding set 66 can be tensioned against the side wall 26 (by applying appropriate pressure via the securing element 68).

The solution according to the invention enables simple and space-saving storage of the suction hose 22. This can be around the Wind the side wall 26 and a corresponding set of turns 66 can then also be "held together".

A securing element 68 forms, in particular, a flexible tensioning element, the flexibility in turn being advantageously achieved by means of an elongation elasticity.
