Abstract

A venting device with a splash guard for deflection of splashing water entering the interior of the venting device has slats with a front section arranged at the exterior. Venting slots are formed between the front sections. At least one of the slats has a deflection section arranged at the interior and a central section connecting deflection section and front section. The front section and the deflection section are angled relative to the central section. The front section of the at least one slat in the operating position of the venting device extends from the central section toward the top side. The deflection section extends in the operating position from the central section toward the bottom side. The deflection section has a region oriented at an angle of less than 90° relative to the central section. A power tool with such a venting device is provided.

First claim

What is claimed is:

1 . A venting device with a splash guard for at least partial deflection of splashing water advancing from an exterior of the venting device in a direction toward an interior of the venting device, the venting device comprising:
slats, each comprising a front section arranged at the exterior, wherein venting slots are formed between the front sections; wherein at least one of the slats comprises a deflection section arranged at the interior and further comprises a central section, wherein the deflection section is connected by the central section to the front section, wherein the front section is angled relative to the central section, and wherein the deflection section is angled relative to the central section; wherein the venting device comprises an operating position and the venting device comprises a top side and a bottom side, relative to a vertical direction, in the operating position; wherein the front section of said at least one slat in the operating position extends from the central section in a direction toward the top side; wherein the deflection section of said at least one slat in the operating position extends from the central section in a direction toward the bottom side and wherein the deflection section comprises a region that is oriented at an angle of less than 90° relative to the central section.

2 . The venting device according to claim 1 , wherein the region of the deflection section and the central section are positioned at an angle of less than 60° relative to each other.

3 . The venting device according to claim 1 , wherein the deflection section at least partially overlaps a correlated venting slot in a viewing direction from the exterior to the interior.

4 . The venting device according to claim 1 , wherein the central section and the deflection section comprise a common surface, wherein the common surface is facing the exterior, and wherein the common surface has a concave cross-sectional shape when viewed in a cross section perpendicular to a longitudinal direction of said at least one slat.

5 . The venting device according to claim 4 , wherein the concave cross-sectional shape of the common surface follows a circular arc line.

6 . The venting device according to claim 1 , wherein the central section in the operating position extends transversely or perpendicularly to the vertical direction.

7 . The venting device according to claim 1 , wherein a plurality of said at least one slat, each provided with the deflection section and the central section, are provided.

8 . The venting device according to claim 7 , wherein at least one of the deflection sections comprises an outer surface facing the exterior and is shaped and arranged such that, in the operating position, water can drip from the outer surface onto the central section of the neighboring slat.

9 . The venting device according to claim 7 , wherein the plurality of said at least one slat are arranged in a stair arrangement.

10 . The venting device according to claim 7 , wherein at least one of the deflection sections comprises an inner surface facing the interior and is shaped such that in the operating position water can drip from the inner surface onto the neighboring slat.

11 . The venting device according to claim 7 , wherein the central sections of the plurality of said at least one slat in the operating position are arranged adjacent to each other at least in sections thereof in the vertical direction.

12 . The venting device according to claim 11 , wherein the central sections are arranged parallel adjacent to each other at least in sections thereof.

13 . The venting device according to claim 11 , wherein the plurality of said at least one slat include a first slat and a second slat, wherein the central section of the first slat comprises a first surface facing the exterior and wherein the central section of the second slat comprises a second surface facing the exterior, wherein the second surface is spaced apart at a first distance from the first surface, and wherein at least the front section of the second slat extends across a front region amounting to at least 30% of the first distance.

14 . The venting device according to claim 13 , wherein the plurality of said at least one slat include a third slat, wherein the central section of the third slat comprises a third surface facing the exterior, wherein the second surface comprises a second distance relative to the third surface, and wherein at least the deflection section of the second slat extends across a deflection region amounting to at least 30% of the second distance.

15 . The venting device according to claim 7 , wherein the plurality of said at least one slat have the same shape.

16 . A power tool comprising:
a venting device with a splash guard for at least partial deflection of splashing water advancing from an exterior of the venting device in a direction toward an interior of the venting device, the venting device comprising:
slats, each comprising a front section arranged at the exterior, wherein venting slots are formed between the front sections;
wherein at least one of the slats comprises a deflection section arranged at the interior and further comprises a central section, wherein the deflection section is connected by the central section to the front section, wherein the front section is angled relative to the central section, and wherein the deflection section is angled relative to the central section;
wherein the venting device comprises an operating position and the venting device comprises a top side and a bottom side, relative to a vertical direction, in the operating position;
wherein the front section of said at least one slat in the operating position extends from the central section in a direction toward the top side;
wherein the deflection section of said at least one slat in the operating position extends from the central section in a direction toward the bottom side and wherein the deflection section comprises a region that is oriented at an angle of less than 90° relative to the central section;
wherein the power tool is configured to be positioned in a position of use on a flat ground; wherein the venting device is in an operating position when the power tool is in the position of use.

17 . The power tool according to claim 16 , wherein the power tool, relative to the flat ground, comprises a top end and a bottom end, wherein the venting device is arranged at the bottom end of the power tool.

18 . The power tool according to claim 16 , wherein the power tool further comprises a housing with a housing wall, wherein the venting device is part of the housing wall, wherein the housing interior of the housing is arranged at the interior of the venting device, wherein the exterior of the venting device is positioned outside of the housing, and wherein the power tool is configured to suck in air through the venting device from the exterior to the interior.

19 . The power tool according to claim 16 , wherein the power tool further comprises at least one electrically operated component, wherein the venting device in the position of use of the power tool is arranged at least partially below all of the at least one electrically operated component.

20 . The power tool according to claim 16 , wherein the power tool is a high-pressure washer.
