Definitions
- the invention relates to a hand-guided swimming pool vacuum cleaner comprising a main body having a housing with an impeller which can be driven via an electric motor, which housing has an inlet opening in a bottom region and an outlet opening on an outlet side, wherein a collecting container receptacle for accommodating a collecting container is arranged in the region of the outlet opening, and wherein a rod receptacle for releasable connection to a guide rod is arranged in the region of the outlet side.
- a hand-guided swimming pool vacuum cleaner is known, the housing of which has a lateral outlet opening to which a collection container for dirt is connected. Above the outlet opening, the housing has a rigid receptacle for a guide rod.
- Rigid, i.e. non-pivoting guide rods have the disadvantage that when guiding the swimming pool vacuum cleaner at the bottom of the swimming pool, the housing may tip over, which has a negative effect on the cleaning function. Furthermore, if the swimming pool vacuum cleaner is handled incorrectly—for example, when moving the swimming pool vacuum cleaner while the impeller is stationary and/or when lifting the swimming pool vacuum cleaner out of the water—back-soiling from the collection container cannot be ruled out.
- U.S. Pat. No. 10,704,282 B2 discloses a hand-guided swimming pool vacuum cleaner in which a connecting fork of a guide rod is connected in a hinged manner to the housing.
- the rod receptacle is arranged on a guide fork which is pivotably connected to the housing about a pivot axis, wherein the pivot axis—as viewed in plan view—is arranged at a distance from a center of mass of the swimming pool vacuum cleaner, wherein the center of mass is arranged between the pivot axis and the outlet opening.
- the center of mass is thus arranged on a side facing the outlet side of a plateau of the swimming pool vacuum cleaner containing the pivot axis.
- the housing due to the position of the center of mass between the pivot axis and the outlet opening, the housing—as soon as the swimming pool vacuum cleaner is raised with the guide rod—is pivoted by gravity in relation to the guide fork in such a way that the outlet opening together with the collection container comes to rest at the lowest point. This effectively prevents dirt particles from the collection tank from flowing back into the swimming pool.
- Another effect of the pivotable guide fork is that during the guide movement the bottom area is guided parallel to the pool floor and tilting movements are avoided. The cleaning effect can thus be increased.
- a robust connection between the guide fork and the housing is achieved if the housing and the guide fork are pivotably connected to one another via two pivot bearings spaced apart from one another, wherein each pivot bearing has a bearing journal and a bearing bore rotatably accommodating the bearing journal, wherein in particular at least one bearing journal is formed by the housing and at least one bearing bore is formed by the guide fork.
- the two pivot bearings are arranged on side walls of the housing facing away from one another, wherein the distance between the two pivot bearings preferably corresponds at least to the—in particular largest—diameter of the, for example, circular inlet opening.
- the guide fork has a defined pivoting range, wherein at least one end position of the pivoting range is defined by at least one stop, preferably arranged on the housing, for a projection corresponding to this stop.
- At least one preferably pin-like projection is formed by the guide fork and at least one stop is formed by the housing.
- at least one preferably pin-like projection is formed by the housing and at least one stop is formed by the guide fork.
- At least one stop is formed by a guide rail, wherein the projection is guided in or on the guide rail.
- the guide rail can be formed, for example, by an integrally formed strip.
- the pivoting range is about 60° to 120° ⁇ 10°, preferably 90° ⁇ 10°.
- the housing has at least one bearing journal and the guide fork has at least one bearing bore, wherein the guide fork is arranged with the bearing bore on the bearing journal so as to be rotatable about the latter.
- This enables secure fastening of the guide fork to the housing and simple assembly.
- the rod receptacle has a preferably cylindrical journal for accommodating a tubular guide rod.
- the journal has at least one bore extending transversely to the longitudinal axis of the rod receptacle for accommodating an elastic latching element. This enables simple and safe assembly and disassembly of the guide rod on the guide fork.
- the rod receptacle is operationally arranged in the area of the outlet side of the housing.
- the guide fork and/or the housing can be made of plastic, for example.

Description
- The invention relates to a hand-guided swimming pool vacuum cleaner comprising a main body having a housing with an impeller which can be driven via an electric motor, which housing has an inlet opening in a bottom region and an outlet opening on an outlet side, wherein a collecting container receptacle for accommodating a collecting container is arranged in the region of the outlet opening, and wherein a rod receptacle for releasable connection to a guide rod is arranged in the region of the outlet side.
- Furthermore, from
EP 2 989 270 B1 a hand-guided swimming pool vacuum cleaner is known, the housing of which has a lateral outlet opening to which a collection container for dirt is connected. Above the outlet opening, the housing has a rigid receptacle for a guide rod. - Rigid, i.e. non-pivoting guide rods have the disadvantage that when guiding the swimming pool vacuum cleaner at the bottom of the swimming pool, the housing may tip over, which has a negative effect on the cleaning function. Furthermore, if the swimming pool vacuum cleaner is handled incorrectly—for example, when moving the swimming pool vacuum cleaner while the impeller is stationary and/or when lifting the swimming pool vacuum cleaner out of the water—back-soiling from the collection container cannot be ruled out.
- U.S. Pat. No. 10,704,282 B2 discloses a hand-guided swimming pool vacuum cleaner in which a connecting fork of a guide rod is connected in a hinged manner to the housing.
- Similar pool cleaners are known from
publications FR 2 430 494 A1,FR 3 080 879 A1 or ES 1 047 768 U. - It is the object of the invention to reliably prevent back-soiling in a swimming pool vacuum cleaner of the type mentioned at the beginning, in particular when removing it from the swimming pool.
- According to the invention, this is achieved in that the rod receptacle is arranged on a guide fork which is pivotably connected to the housing about a pivot axis, wherein the pivot axis—as viewed in plan view—is arranged at a distance from a center of mass of the swimming pool vacuum cleaner, wherein the center of mass is arranged between the pivot axis and the outlet opening.
- The center of mass is thus arranged on a side facing the outlet side of a plateau of the swimming pool vacuum cleaner containing the pivot axis.
- Due to the position of the center of mass between the pivot axis and the outlet opening, the housing—as soon as the swimming pool vacuum cleaner is raised with the guide rod—is pivoted by gravity in relation to the guide fork in such a way that the outlet opening together with the collection container comes to rest at the lowest point. This effectively prevents dirt particles from the collection tank from flowing back into the swimming pool. Another effect of the pivotable guide fork is that during the guide movement the bottom area is guided parallel to the pool floor and tilting movements are avoided. The cleaning effect can thus be increased.
- A robust connection between the guide fork and the housing is achieved if the housing and the guide fork are pivotably connected to one another via two pivot bearings spaced apart from one another, wherein each pivot bearing has a bearing journal and a bearing bore rotatably accommodating the bearing journal, wherein in particular at least one bearing journal is formed by the housing and at least one bearing bore is formed by the guide fork. In order to enable stable guidance of the swimming pool vacuum cleaner, it is advantageous if the two pivot bearings are arranged on side walls of the housing facing away from one another, wherein the distance between the two pivot bearings preferably corresponds at least to the—in particular largest—diameter of the, for example, circular inlet opening.
- In one embodiment variant of the invention, it is provided that the guide fork has a defined pivoting range, wherein at least one end position of the pivoting range is defined by at least one stop, preferably arranged on the housing, for a projection corresponding to this stop.
- One embodiment according to the invention provides that at least one preferably pin-like projection is formed by the guide fork and at least one stop is formed by the housing. Alternatively or additionally, it can be provided that at least one preferably pin-like projection is formed by the housing and at least one stop is formed by the guide fork.
- In an embodiment of the invention that is simple to manufacture, it is provided that at least one stop is formed by a guide rail, wherein the projection is guided in or on the guide rail. The guide rail can be formed, for example, by an integrally formed strip.
- To avoid uncontrolled pivoting movements, it is advantageous if the pivoting range is about 60° to 120°±10°, preferably 90°±10°.
- Preferably, the housing has at least one bearing journal and the guide fork has at least one bearing bore, wherein the guide fork is arranged with the bearing bore on the bearing journal so as to be rotatable about the latter. This enables secure fastening of the guide fork to the housing and simple assembly.
- In one embodiment variant of the invention, it is provided that the rod receptacle has a preferably cylindrical journal for accommodating a tubular guide rod. In particular, it is provided within the scope of the invention that the journal has at least one bore extending transversely to the longitudinal axis of the rod receptacle for accommodating an elastic latching element. This enables simple and safe assembly and disassembly of the guide rod on the guide fork.
- Preferably, it is provided that the rod receptacle is operationally arranged in the area of the outlet side of the housing.
- The guide fork and/or the housing can be made of plastic, for example.

FIG. 15 shows the guide fork of the swimming pool vacuum cleaner in another axonometric view. - The swimming
pool vacuum cleaner 1 shown inFIGS. 1 to 5 has amain body 2 having ahousing 3, acover part 4 and asuction mouth part 5. An electric motor, which is not shown in closer detail, and animpeller 6 driven by the electric motor, which is designed as an axial impeller, are arranged inside the housing 3 (FIG. 3 ). The electric motor is powered, for example, by a rechargeable battery not shown further, which is arranged in a sealed space of thehousing 2 below thecover part 5. The impeller axis oriented normal to a contact surface during operation is designated withreference sign 6 a. The contact surface is formed, for example, by a swimming pool floor. - The
housing 2 has abottom area 7 with an inlet opening 8 and anoutlet side 9 with a lateral outlet opening 10. Theimpeller 6 is arranged immediately downstream of the inlet opening 8 in thehousing 2 to achieve a high cleaning effect. Thecross-sectional area 10 a of the outlet opening 10 is formed transversely, for example approximately normal to thecross-sectional area 8 a of the inlet opening 8 (seeFIG. 9 ). In the embodiment shown inFIG. 1 toFIG. 5 , a plate-shapedsuction mouth part 11 is arranged below theinlet opening 8, wherein thesuction mouth part 5 hascontact elements 11 formed by brushes, for example, which define acontact plane 11 a of the swimmingpool vacuum cleaner 1. - The
impeller 6 draws in water through thesuction mouth part 11 and the inlet opening 8 of thehousing 2 and conveys it according to the arrows P to the lateral outlet opening 10 (FIG. 1 andFIG. 5 ). Thelateral outlet opening 10 has acollection container receptacle 12 which is formed, for example, by a raised circumferential rim, bead or flange for a collection container not shown further, which can be formed, for example, by a filter bag. The lateral outlet opening 10 with theflow outlet axis 10 b formed perpendicular to theimpeller axis 6 a has the advantage that the contaminants remain in the collection container when the electric motor is switched off and it is more difficult for them to seep back into the swimming pool. - The swimming
pool vacuum cleaner 1 can be guided along the bottom of the swimming pool by means of aguide rod 13 indicated by dashed lines inFIG. 1 . Theguide rod 13 is firmly connected to the swimmingpool vacuum cleaner 1 via aguide fork 14. Theguide fork 14 has twofork arms fork arm housing 3 via a respective pivot bearing 15 so as to be pivotable about apivot axis 15 a. Thepivot axis 15 a is arranged as close as possible to thecontact plane 11 a. In the exemplary embodiment, the distance between thepivot axis 15 a and thecontact plane 11 a, denoted by h, is less than half the diameter D of the inlet opening 8. This enables simple guidance of the swimmingpool vacuum cleaner 1 along the contact surface formed by the bottom of the swimming pool. This allows for easy guidance of the swimmingpool vacuum cleaner 1 along the contact surface formed by the bottom of the swimming pool. Thepivot bearings 15 each consist of a bearing bore 16 and abearing journal 17, which is pivotally disposed in the bearing bore 16. For example, the bearing bores 16 are formed by theguide fork 14 and the bearing pins 17 are formed by thehousing 3. Thepivot bearings 15 have a definedpivoting range 13 between two end positions of, for example, 60° to 120°±10°, in particular 90°±10° (FIG. 9 ). - The end positions are defined in each case by two interacting elements, for example a pin-
like projection 18, which interacts with stops A, B. In the exemplary embodiment, the stops are formed by aguide rail 19 in or along which theprojection 18 is guided. Theguide rail 19 is formed, for example, by an integrally formed strip of aguide rail 19 which is formed, for example, by an integrally formed strip. Theguide rail 19 is substantially formed as a circular arc segment around thepivot axis 15 a. A first end position is defined by a first stop A and a second end position by a second stop B of theguide rail 19. In the exemplary embodiment, the stops A, B are formed as radial deflections in the end regions of theguide rail 19. The pin-like projection 18 is formed by the guide fork 14 (FIG. 12 toFIG. 15 ) and theguide rail 19 by the housing 3 (FIG. 9 ,FIG. 11 ) in the illustrated exemplary embodiment. - At an end facing away from the bearing bores 16 of the
pivot bearings 15, theguide fork 14 has, for example, a cylindrical pin-like rod receptacle 20 for thetubular guide rod 13. The, for example, pin-like rod receptacle 20 has at least onerecess 21 extending transversely to thelongitudinal axis 20 a of therod receptacle 20 for accommodating anelastic latching element 22. - The
main body 2 contains all elements of the swimmingpool vacuum cleaner 1 with the exception of theguide fork 14 required for manual guidance and theguide rod 13 which can be attached to it. The swimmingpool vacuum cleaner 1 thus consists of themain body 2 and theguide fork 13. - As shown in particular in
FIG. 2 andFIG. 7 , thepivot axis 15 a is spaced from a center of mass S of themain body 2 of the swimmingpool vacuum cleaner 1—as seen in plan view—with the center of mass S of themain body 2 being considered withoutguide rod 13 and withoutguide fork 13. The distance between the pivot axis S and the center of mass S is denoted by reference sign a. In detail, the center of mass S—as viewed in plan view—is located between thepivot axis 15 a and theoutlet opening 10. The center of mass S is thus located on a side facing the outlet opening 10 of a first plateau ε of the swimmingpool vacuum cleaner 1 containing thepivot axis 15 a. - In other words, the first plateau ε of the swimming
pool vacuum cleaner 1 is distant from a second plateau η extending through the center of mass S and parallel to the first plateau ε by the distance a. The first plateau ε and the second plateau η are thereby arranged perpendicular to thecross-sectional area 8 a of the inlet opening 8 (FIG. 5 ,FIG. 6 ,FIG. 7 ,FIG. 9 ). - Because the center of mass S of the
main body 2 of the swimmingpool vacuum cleaner 1 is arranged between the plateau ε extending through thepivot axis 15 a and theoutlet opening 10, there is a tilting movement of themain body 2 of the swimmingpool vacuum cleaner 1 about thepivot axis 15 a as soon as the swimmingpool vacuum cleaner 1 is lifted from the contact surface G formed by the floor of the swimming pool. In the process, the outlet opening 10—together with the collection container attached to it—tilts downward, as indicated by the arrow K inFIG. 1 . The tilting movement causes the outlet opening 10 to move downward and the container opening—not shown further—of the collection container connected to theoutlet opening 10 is thus directed upward, reliably preventing dirt particles from falling out of or seeping back into the swimming pool from the collection container. - A particularly stable connection between the
guide fork 14 and thehousing 3 can be achieved if thepivot bearings 15 are arranged as far apart as possible. The twopivot bearings 15 are therefore arranged on twosides housing 3 facing away from each other in the illustrated exemplary embodiment. The distance b between the twopivot bearings 15 corresponds at least to the diameter D of the, in particular, circular inlet opening 8 (FIG. 6 ). The twoarms guide fork 14 thus enclose thehousing 3 in the area of theinlet opening 8. This allows safe and precise lateral guidance of the swimmingpool vacuum cleaner 1 by theguide rod 13.
