Description

[0001] The invention relates to a set according to the preamble of claim 1.

[0002] The set is suitable for direct or indirect attachment to a suction device, whereby dust or dirt particles can be removed from a surface using the suction device and the set attached to it.

[0003] According to the present invention, the set comprises at least one holding element, wherein the holding element has at least one handle for guiding the set and at least one, preferably elongated, suction section. At least one suction tube can be fluidically connected to the at least one suction section. Furthermore, the set comprises a cleaning element in the form of a suction brush for collecting dust and dirt particles.

[0004] An indirect attachment of the set with a suction device is typically achieved via a flexible suction hose that connects the holding element to the suction device in terms of fluid dynamics.

[0005] In the sets known from the prior art, the suction tube is fluidically connected to the suction section of the holding element. The cleaning element is also arranged on the suction section, but it is merely positioned there and performs no function when the suction tube is connected to it. Typically, a floor nozzle is located at the end of the suction tube furthest from the holding element, which can be used to remove dust and dirt particles from a surface.

[0006] With previously known sets, it is possible to remove the suction tube from the suction section and slide the cleaning element to the end of the suction section, so that a brush section of the cleaning element contacts the surface to be cleaned. This means that dust and dirt particles are transported via the cleaning element, which is directly connected to the suction section via airflow, into the suction section and thus into the suction device. The cleaning element is particularly suitable for cleaning corners and edges that the floor nozzle cannot reach.

[0007] However, it has now turned out that the operating radius of the holding element with the attached cleaning element is not large enough to, for example, vacuum cobwebs from the ceiling.

[0008] The present application is based on the task of providing a set with a cleaning element whose handling is improved compared to the prior art.

[0009] The underlying problem is solved according to the invention by means of a set comprising the features of claim 1. Advantageous embodiments are described in dependent claims 2 to 9.

[0010] The set according to the invention is characterized in that the set can be transferred at least between a first position, a second position and a third position.

[0011] When the set is in the first position, the suction tube is fluidically connected to the suction section of the holding element, while the cleaning element is attached to the suction section of the holding element. In this position, the cleaning element serves no function but is simply held in place by the suction section. Dust and dirt particles are drawn into the suction section via the suction tube. Typically, a floor nozzle is attached to the end of the suction tube furthest from the holding element to increase the cleaning area and prevent scratches that the suction tube might cause on the surface being cleaned. In this position, the set is used, for example, for cleaning floor surfaces.

[0012] When the set is in the second position, only the cleaning element is fluidly connected to the suction section of the holding element in such a way that dust and dirt particles are directed through the cleaning element into the suction section. This means that the suction tube is removed from the suction section and the cleaning element is positioned at the end furthest from the handle. Dust and dirt particles are then introduced into the suction section via the cleaning element. The cleaning element is particularly useful for cleaning corners and hard-to-reach areas.

[0013] However, to increase the operating radius of the set, the inventive set provides that, when the set is in the third position, the cleaning element is arranged at the end of the suction tube furthest from the handle, while the suction tube is fluidically connected to the suction section of the holding element, so that dust and dirt particles can be guided from the cleaning element through the suction tube and into the suction section. That is, the cleaning element is located away from the suction section of the holding element and is attached to the suction tube. The operating radius is thus increased by the length of the suction tube. This offers the advantage that dust and dirt particles can also be vacuumed up from more distant, hard-to-reach corners and edges. While it would also be possible to omit the cleaning element and use direct suction with the suction tube, this design offers the advantage of increased efficiency.However, experience has shown that this can lead to scratches and unsightly stains on the surfaces being vacuumed, which are prevented when using the cleaning element.

[0014] The set according to the invention combines a sliding cleaning element with a loose cleaning element that can be detachably attached to the suction tube, thus combining the advantages of both variants. Not only is it more difficult to lose or misplace the cleaning element, as it can always be reattached to the suction section, but it also allows for flexible use on either the suction tube or the suction section, so that the operating radius can be extended or shortened depending on the application. Removing the suction brush from the suction section also eliminates the need for an additional suction brush to be attached to the suction tube, thus saving material. Therefore, the set according to the invention can be used to vacuum a wide variety of surfaces, such as floors, walls, cabinets, corners, baseboards, etc.

[0015] Preferably, the suction pipe is a telescopic pipe, so that the operating radius can be increased even further.

[0016] One embodiment of the invention provides that the cleaning element has at least one nozzle, wherein the diameter of the nozzle is larger than the diameter of the suction pipe. At least the nozzle of the cleaning element can thus be slid onto the suction pipe.

[0017] In order to enable the retaining element to be slid onto the suction section, an advantageous embodiment of the invention provides that the diameter of the nozzle is larger than the diameter of the suction section of the retaining element.

[0018] Preferably, the cleaning element has a brush section which can be guided over the surface to be cleaned in the second and third positions of the set. The brush section is preferably also pushed onto the suction section in the first position.

[0019] Regarding the arrangement of the cleaning element on the suction section, it is particularly advantageous if the suction section has at least one guide groove on an outer wall and the cleaning element has at least one spring tab on an inner wall. The spring tab of the cleaning element can be inserted into the guide groove of the suction section, and the cleaning element can be displaced in a longitudinal direction of the suction section. A longitudinal axis of the suction section is preferably arranged parallel to a longitudinal axis of the guide groove. Due to the guidance of the spring tab in the guide groove, rotation of the cleaning element about the longitudinal axis of the suction section is prevented. The cleaning element can thus be unambiguously positioned on the suction section.

[0020] Alternatively, it is conceivable that the suction section has at least one spring tab on an outer wall and the cleaning element has at least one guide groove on an inner wall, wherein the spring tab of the suction section can be inserted into the guide groove of the cleaning element and the cleaning element can be displaced in a longitudinal direction of the suction section. With this alternative, rotational movement of the cleaning element about the longitudinal axis of the suction section is also prevented, and the cleaning element can thus be unambiguously positioned on the suction section.

[0021] Furthermore, it can be advantageous for the guide groove to have an insertion groove at one end, away from the handle, preferably T-shaped or funnel-shaped. Such a design facilitates the insertion of the spring tab into the guide groove. This is partly because the insertion groove acts as a guide to direct the spring tab into the guide groove. Advantageously, the spring tab can be inserted into the insertion groove with a rotary motion.

[0022] According to a particularly preferred embodiment of the invention, the at least one cleaning element has at least one locking element which interacts with at least one corresponding first receptacle of the suction section of the holding element, so that the cleaning element can be locked in the first position of the set on the suction section and / or interacts with at least one corresponding second receptacle of the suction section of the holding element, so that the cleaning element can be locked in the second position of the set on the suction section and / or interacts with at least one corresponding third receptacle of the suction tube, so that the cleaning element can be locked in the third position of the set on the suction tube.

[0023] The at least one locking element corresponds to the three receptacles in such a way that the cleaning element is detachably fixed to the suction section or suction tube. This prevents the cleaning element from shifting or unintentionally detaching from the suction section or suction tube.

[0024] An advantageous embodiment of the invention provides that the locking element of the cleaning element is designed in the form of a spring rocker. The spring rocker is preferably shaped such that it engages in one of the aforementioned receptacles and detachably connects the cleaning element to the suction section or suction tube.

[0025] According to an advantageous embodiment of the invention, the first receiving point of the suction section and / or the second receiving point of the suction section and / or the third receiving point of the suction tube are each formed in the form of a recess, preferably in the form of a square hole or a depression, preferably a groove. The spring rocker and the square hole or the depression correspond to each other in such a way that the cleaning element remains in the respective position without further intervention.

[0026] It is advantageous if the cleaning element includes a button, whereby the button and the locking element interact in such a way that the locking element lifts when the button is pressed. This has the advantage that, when the button is pressed, the locking element is lifted to such an extent that it comes out of the square hole or recess in the suction tube or suction section, and the cleaning element can then be slid off the suction tube or suction section. Alternatively, the cleaning element can be moved from the first position of the set to the second position of the set, or vice versa.

[0027] Ideally, the cleaning element could be used flexibly on different suction devices with different holding elements.

[0028] An embodiment of the invention is shown schematically in the drawings and is described in more detail below. It shows: Figure 1 is a schematic partial representation of a set according to the invention with a cleaning element in a first position; Figure 2 is a sectional view of the set according to the invention.

The cleaning element 5 is so attached to the suction section 4 attached that on one of the handles 3 far end 9 of the suction section 4 the intake manifold 6 It is mountable. This means that the suction section 4 both the stub 7 as well as the brush area 8 of the cleaning element 5 penetrates the intake manifold. 6 is fluidically connected to the suction section 4connected. In the first position of the set 1 is a longitudinal axis 10 of the intake manifold 6 preferably coaxial to a longitudinal axis 11 of the suction section 4 arranged.

[0030] A second position of the set according to the invention 1 will be in the Figure 2 shown. To the set 1 to move from its first position to its second position, the intake manifold 6 from the suction section 4 removed. The intake manifold 6 is not required in the second position. Accordingly, the intake manifold... 6 not in the Figure 2 shown. Instead of the intake manifold. 6 The cleaning element is now located 5 on the handle 3 far end 9 of the suction section 4. For this purpose, the cleaning element is 5 along the longitudinal axis 11 of the suction section 4towards the end 9 pushed so that now only the stub remains 7 of the cleaning element 5 from the suction section 4 is penetrated. The brush area 8 stands from the end 9 of the suction section 4 from the perspective. The cleaning element 5 and the suction section 4 They are fluidically connected in such a way that dust and dirt particles are carried through the brush area 8 of the cleaning element 5 into the suction section 4 are conductive.

[0031] A diameter D1 of the stub 7 is larger than a diameter D2 of the suction section 4, so that the cleaning element 5 on the suction section 4 can be pushed.

[0032] The Figure 3 shows the retaining element 2 with the handle 3 as well as the suction section 4.At one of the suction sections 4 far end 12 of the handle 3 There is an opening 13, into which a suction hose (not shown here) can be inserted.
