    The invention relates to an underwater cleaner, in particular for a swimming pool, with a housing in which a particular battery-operated pump with an electric motor and an impeller is arranged, wherein the housing has an inlet channel with an inlet opening and an outlet channel with an outlet opening, and wherein the impeller axis is arranged normal to the opening cross-section of the inlet channel.
    From the website http://www.youtube.com/watch v=HwwWE2iRVL4 a Unterwasserstaubsauger of the aforementioned type with an axial pump impeller is known, which is driven by a battery-powered electric motor. The electric motor including the impeller is arranged in a bell-shaped rotationally symmetrical housing, wherein the electric motor is arranged on the upstream side of the impeller. However, this has the disadvantage that the suction effect is relatively low. A protective grid is not provided.
    US 4,204,298 A discloses a vacuum suction device with an axial fan impeller, which is arranged close to the inlet opening of the housing. As protection, a grid is provided upstream of the impeller.
    An apparatus for cleaning ships with rotating brushes and an impeller is known from US 5,174,222 A.
    Further underwater cleaners are disclosed in US 2011/0314617 A1, US Pat. No. 4,619,217 A, US Pat. No. 4,604,960 A. Known underwater cleaners either have a poor cleaning effect, or are relatively expensive.
    In order to achieve a good suction effect, a relatively high electrical drive power is required in most conventional electrically operated submarine cleaners. However, this requires relatively large-sized drive motors, and - in the case of battery operation - large and heavy battery packs, which increases the production cost and reduces the handling.
    Low-power underwater cleaners generally have the problem that light particulates and small particles can be pumped through the impeller into the bag, but heavy and / or larger debris such as leaves, wood particles, larger insects, soil and coarser sand particles upstream of the bag Impeller in the inlet channel are held in suspension and can not be promoted in the filter bag. If the underwater cleaner is raised or switched off, the dirt particles held in suspension by the suction effect of the impeller sink off again due to their own weight and lead to back-soiling of the swimming pool.
    The object of the invention is to develop the simplest and most economical underwater vacuum cleaner, which has a good cleaning effect at low electrical power.
    According to the invention this is achieved in that upstream of the impeller, a sheet catcher is arranged, wherein preferably the sheet catcher is disposed within the inlet channel.
    It is particularly advantageous for the sheet-catching device to have at least one segment which is preferably pivotably mounted in the housing and defines at least one catching pocket in an operating position with the catching pocket preferably being arranged adjacent to a preferably nozzle-like cross-sectional reduction of the inlet channel. The sheet-catching device may, for example, have at least two preferably hemispherical segments, wherein a passage opening with a nozzle-like reduced cross-section is preferably formed between the two segments.
    Heavy and / or larger particles of dirt, such as leaves, are sucked into the region of the inlet channel downstream of the sheet-catching device due to the speed increase in the area of the cross-section reduction and held in suspension when the suction force is insufficient to allow the particles through the impeller to promote in the connected to the outlet sump. If the underwater cleaner is raised or the electric motor is switched off to drive the impeller, the dirt particles previously held in suspension will sink into the catching bag. As a result, a Rückverschmutzen the swimming pool is avoided. The catch bag can be emptied from the swimming pool after removing the underwater cleaner. The pivoting of the segments allows easy emptying and cleaning of the catch pockets. 3/21 3
    It is particularly advantageous if the sheet catching device is fastened detachably in or at the inlet channel or directly or indirectly to the housing, preferably via a form-locking connection. Thus, the sheet catcher may be formed as a modular element and only when needed - if it is to be expected as heavy or large dirt particles - are installed in or on the inlet channel. It is particularly advantageous if an inlet pipe forming the inlet channel together with the sheet-catching device is preferably detachably connected to the housing via a form-locking connection.
    In order to avoid injuries by the rotating impeller, the inlet opening upstream of the impeller may be provided with a protective grid having a number of passages, wherein the protective grid can be arranged and fastened within the inlet channel-particularly preferably detachably. The protective grid can be modular and can be removed or installed as needed.
    In a particularly advantageous embodiment of the invention, it is provided that the protective grid is stepped and at least two spaced from each other in the direction of the impeller axis of the impeller, preferably formed normal to the impeller axis areas, wherein the protective grid a the wheel axis intersecting central region and at least one of the Has housing adjacent annular region and wherein axial passage openings are arranged in the central region and / or in the annular region. As a result, the protective grille has passage openings arranged in different planes, as a result of which dirt can be extracted from the swimming pool floor at different distances. In order to be able to reliably remove larger contaminants such as leaves or the like with the underwater cleaner, it is advantageous if at least one preferably cylindrical annular gap section is formed between the outer edge of the central region and the inner edge of the annular region, wherein preferably the outer edge and the inner edge are connected to each other via at least one preferably parallel to the impeller axis formed connecting web.
    The central region and the annular region can have a substantially circular floor plan, but also have a plan deviating from the circular shape. The ring area itself can therefore also have a different from the circular ring 4/21 4, for example, angular shape. Thus, in addition to the circular shape also oval, elliptical, but also square - square, triangular, n-shaped floor plans for central area and ring area conceivable. In particular, in the case of the circular shape of the - preferably average - diameter of the central region about half the diameter of the annular region +/- 10% correspond. The annular gap section or central region can have a cylindrical or truncated cone shape, with general cylindrical or conical shapes deviating from the circular shape being possible in addition to a circular cylindrical or circular conical shape. Furthermore, the annular gap section or central region can also have the shape of a prism.
    In this case, at least one preferably cylindrical annular gap section may be formed between the outer edge of the central region and the inner edge of the annular region, wherein preferably the outer edge and the inner edge are connected to each other via at least one preferably parallel to the impeller axis connecting web. The annular gap section has at least one preferably ring-segment-shaped radial passage opening. Larger impurities can be sucked in without problems if the radial passage opening of the annular gap section has a larger cross-section than the largest axial passage opening of the central region or the annular region. Thus, larger contaminants are sucked directly through the annular gap section.
    A first embodiment of the invention provides that the distance between the impeller and central area is greater than between the impeller and ring area. Alternatively, it is also possible that the distance between the impeller and central area is smaller than between the impeller and ring area.
    In order to optimize the suction, it can be provided that the central region and the annular region have differently sized passage openings and / or different passage opening densities. Alternatively or additionally, it can also be provided that the central region or the annular region-at least in sections-has at least one closed wall region, preferably formed without an opening.
    Instead of a fixed design of the passage openings can also be provided that the passage openings of the protective grid - preferably of 5/21. 5
    Zentralbereichs- and / or the annular region and / or the annular gap portion are formed via at least one control member adjustable and / or closable. Thus, the suction effect can be adapted quickly to the respective cleaning case quickly. The control members can be formed by simple slide or flap elements, which can block or release a number of passages.
    In order to prevent backscattering when switching off the electric motor within the pool, it is advantageous if the outlet opening is arranged laterally on the housing, wherein preferably the main flow axis of the outlet opening is arranged transversely to the impeller axis, particularly preferably normal to the impeller axis.
    The housing may have a plurality of circumferentially spaced apart support members in the peripheral region of the inlet opening, wherein preferably the support elements are formed by sliders, scooters or brushes. The support elements ensure that the edge of the inlet opening of the housing is always at the correct distance from the bottom of the pool in order to achieve a good cleaning effect.
    The invention will be explained in more detail below with reference to FIG.

    The underwater cleaner 1, for example for a swimming pool, has a housing 2, in which a battery-powered pump 3 is arranged. The pump 3 has a driven by an electric motor 4 impeller 5, which is designed as Axiallaufrad 5. The power supply of the electric motor 4 may be via a rechargeable battery, which may be located in or on the housing 2 or in a non-illustrated battery case outside the water. The impeller axis is designated by 5a. The pump 3 sucks in water through the inlet opening 6 'of the inlet channel 6 and conveys it according to the arrows S to the side outlet opening 7' of the outlet channel 7, to which a non-illustrated collecting container can be connected. The lateral outlet opening 7 'with the main outflow axis 7a formed normal to the impeller axis 5a has the advantage that the contaminants remain in the collection container 22 when the pump 3 is switched off and at least makes it difficult, if not impossible, to return to the pool.
    The underwater cleaner 1 can be guided over the guide rod 14 along the bottom of the pool.
    The impeller 5 is arranged in the in the end region of the substantially straight formed inlet channel 6. In the exemplary embodiment, the inlet channel 6 is for the most part formed by an inlet pipe 16 which is detachably fastened to the housing 2, for example via at least one form-locking connection 17 (bayonet closure).
    Upstream of the impeller 5, a sheet catcher 18 is disposed within the inlet channel 6. The sheet catcher 18 consists of at least one flap-like segment 19, which is pivotally mounted on the inlet pipe 16 via a joint 20 in the region of the inlet opening 6 '. In the exemplary embodiment, the inlet pipe 16 in the region of the inlet opening 6 'on two diametrically opposed joints 20, wherein each joint 20 is formed for the articulated receiving a respective half-shell or semi-circular segment 19. Two segments 19 are arranged opposite one another in the inlet tube 16 via the two joints 20, wherein a nozzle-like cross-section reduction 21 of the inlet channel cross-section is formed between the mutually facing edges 19a of the segments 19, which causes a local increase in the flow velocity in this region. As a result, relatively large and / or heavy dirt particles, such as leaves, pebbles, soil, insects or the like entrained and transported in the inlet channel 6 between the sheet catcher 18 and the impeller 5. If the dirt particles are too large to be conveyed via the impeller 5 into the collecting container 23, they are held in suspension by the suction of the impeller 5 in the inlet channel 6. As soon as the electric motor 4 is turned off, or the underwater cleaner 1 is lifted, in particular lifted out of the water, these suspended particles sink by their own weight and accumulate in between the segments 19 and the walls 6 " of the inlet channel 6 spanned catch pockets 22, from where they can be easily removed later.
    If the sheet catcher 18 is not needed, then it can easily be omitted, since the segments 19 are detachably connected to the inlet pipe 16. In the same way, it is possible to detach the entire inlet pipe 16 together with the sheet-catching device 18 from the housing 2 and to use the underwater cleaner 1 without inlet pipe 16 and sheet-catching device 18.
    To protect against injury, a protective grille 8 may be provided immediately upstream of the impeller 5, especially when the underwater cleaner without sheet catcher 18 is used. But even when inserted sheet catcher 18, the protective grid 8 is of great advantage, for example, in children's hands, to avoid injury.
    The protective grid 8 is arranged in the fastening area 2 'of the inlet tube 16 and screwed to the housing 2 via fastening screws 9. The protective grid 8 is stepped and has at least two mutually spaced in the direction of the impeller axis 5a from the impeller 5 areas, namely a wheel axis 5a intersecting central region 8a and at least one adjacent to the housing 2 annular region 8b, wherein axial passage openings 10a, 10b are arranged in the central region 8a and / or in the annular region 8b. In the exemplary embodiment, the central region 8a is further away from the impeller 5 than the annular region 8b. But it is also conceivable vice versa. It is essential that cylindrical annular gap sections 11 between connecting webs 12 are formed between the outer edge 8a 'of the central region 8a and 8/21 8 and the inner edge 8b' of the annular region 8b. About the parallel to the impeller axis 5a formed connecting webs 12, the outer edge 8a 'and the inner edge 8b' are interconnected, as shown in Fig. 15. In the annular gap sections 11 radial passage openings 10c are provided whose cross sections are larger than the cross sections of the axial passage openings 10a, 10b. This makes it possible to suck larger contaminants, such as leaves or the like, which do not fit through the smaller axial passage openings 10a, 10b, through the radial passage openings 10c. The height h of the radial passage openings 10c may correspond substantially to the maximum transverse extent of the largest axial passage opening.
    The radial and axial passage openings should be dimensioned in their extent that reliable penetration of fingers can be prevented by children in the impeller area to avoid injury.
    D is the diameter of the central region 8a, denoted by D the largest diameter of the annular region 8b. The diameter d of the central region 8a is slightly larger than half the diameter D of the annular region 8b.
    The passage openings 10a, 10b of the central area 8a and of the annular area 8b can be of different sizes or with different density (number per unit area). Alternatively or additionally, the central region 8a or the annular region 8b may be designed to be closed at least in sections in order to generate targeted pressure differences and thus to optimize the suction effect in individual regions.
    In the peripheral region of the inlet opening 6 a plurality of circumferentially spaced support members 13 are arranged. The support elements 13 may be formed by strips, sliders, scooters, brushes or the like. 9.21
