Description

Material level display, collecting device with material level display and gardening machine

Technical Field

The utility model relates to a material level display that is used for collecting device, especially grass collecting device of horticulture processing machine.

Background

A level indicator for a collecting device is known, for example, from EP 0639321B 1. The disadvantages of such a level display are: cuttings may clog the level display and cause false displays. Furthermore, such a level display is not easily readable visually, since the visibility of the entire area of the flap is more indicative of a full collecting basket, which is empty in this state of the flap, and the low visibility of the flap is more indicative of an empty level, which is full in this state of the flap.

SUMMERY OF THE UTILITY MODEL

The utility model discloses from a material level display, its collecting device who is used for ground processing utensil especially is used for the collection basket of lawn mower, and this material level display has: a structure, in particular a housing having an inlet and an outlet; and a pivotable dynamic pressure generating element (staudruckerzeugmeasuring element), in particular in the form of a flap. It proposes: the dynamic pressure generating element is arranged pivotably between the inlet and the outlet and is connected to a display device for displaying the fill level, which is designed in particular independently of the dynamic pressure generating element. The structure forms at least one channel, in particular an air channel, between the inlet and the outlet. The dynamic pressure generating element is arranged in the structure, in particular pivotably arranged in a region of the structure. "independent" is to be understood here as meaning spatially separated, i.e. in particular not formed by or arranged on the back side of the dynamic pressure generating elements. However, the dynamic pressure generating element may be constructed integrally with the display device. Preferably, the display device covers, encloses or hides the structure in order to enable an improved visibility of the display device. In principle, however, the display device may also be arranged below a window or similar structure. Through according to the utility model discloses a material level display can read the material level directly perceived and definitely favorably, borrow this can improve and read the convenience and thereby improve convenient operation nature.

It is furthermore proposed that the dynamic pressure generating element is displaceably configured by a pressure difference between the inlet and the outlet. The inlet is subjected to an air flow, by means of which, for example, cut material is conveyed from the mower into the collecting basket, in a state in which the level indicator is mounted on the collecting device; while the outlet is subjected to atmospheric or ambient air pressure. Thus, a pressure drop may be created between the inlet and the outlet. The dynamic pressure generating element now acts as an approximately sealing element, so that in particular a pressure difference between the inlet and the outlet can be maintained by closing the structure or the channel at least to the greatest possible extent. A pressure exists on the inlet side of the dynamic pressure generating element, which pressure exists within the collecting device, in particular directly before the inlet; ambient pressure is present on the opposite side (back side) of the dynamic pressure generating element. Thereby preventing, at least to the greatest extent, pressure compensation or gas flow between the inlet and the outlet. To the greatest extent possible, it should be understood that small gas flows, for example leakage gas flows, may be included, which may be caused by gaps and/or tolerances between the structure and the dynamic pressure generating element. Even more precisely, it is advantageous, for reasons of price, complexity and functionality of the apparatus, to dispense with the use of dynamic pressure generating elements and expensive sealing structures between the structures. The sealing structure may also have increased friction (for example due to a flexible sealing lip arranged on the edge structure of the dynamic pressure generating element, which sealing lip bridges the gap for enabling an oscillating movement of the dynamic pressure generating element relative to the structure). The dynamic pressure generating element can thus be displaced even with small air pressure differences on the basis of a light, low-friction and simple bearing and design. Advantageously, the display device reacts sensitively, in particular quickly sensitively, to a pressure difference between the inlet and the outlet or to an unfilled or filled collecting device. In particular, it is thereby possible to achieve a maximally binary display of the fill levels, i.e. "not full" and "full", which makes readability unambiguous and thus increases user friendliness. Furthermore, by means of the small gap size between the structure and the dynamic pressure generating element, for example less than 2mm, in particular approximately 1mm, in the collecting basket for a lawnmower there is little to no cut matter penetrating into the level indicator or being discharged from the outlet, which ensures a continuous and robust function and avoids regular cleaning of the level indicator.

It is furthermore proposed that the dynamic pressure generating element advantageously has substantially the cross-sectional area (internal cross-sectional area) at least one point of the structure. The cross section of the structure advantageously does not change over the displacement path or the oscillation path of the dynamic pressure generating element, so that a constant or constant pressure difference can be maintained over the oscillation path.

It is also proposed that the display device is visible in the first pivoted position and that a further display device, in particular a display device formed from the structure, is exposed in the second pivoted position. The display device has in particular a roof-shaped structure with side walls, which can cover or cover the further display device in a pivotable manner. This makes it possible to dispense with further structural elements for indicating the fill level and to keep the structure simple, stable and/or advantageous.

It is also proposed that the display device forms a first display surface and the structure forms a second display surface, wherein the first display surface or the second display surface is visible by displacement of the display device. In particular, the display device is shifted into or under the structure in the second swing position. No level display is thereby established, which just projects from the collecting device, which makes it robust against external influences and compact. Furthermore, an unambiguous display is enabled, since either the first display device or the second display device is visible. Furthermore, the surface structure of the display device also makes it sufficiently visible at a distance.

It is furthermore proposed that the structure has a first signal color, in particular green, and that the display device has a second signal color, in particular red. The display device or the display devices can be recognized well by the signal colors. By color selection: red and green, the level can be visually and unambiguously indicated to the user, i.e. full red and not full green.

It is furthermore proposed that the dynamic pressure generating element is formed integrally with the display device, in particular is reinforced by a reinforcing element, such as a supporting rod. Thereby reducing complexity, increasing the rigidity of the structure and/or enabling direct coupling of motion from the pressure generating device to the display device. For example, the dynamic pressure generating element and the display device are connected via an angle.

The level indicator also has a form-locking means, in particular a latching means, for releasable connection to the collecting device. The level indicator can therefore be removed and inserted or added (for example, by a simple closing plate or the like on the collecting basket).

Furthermore, a further dynamic pressure generating element may be arranged between the inlet and the outlet or a further outlet. The further dynamic pressure generating element can likewise be pivotably connected to the first dynamic pressure generating element, in particular constructed in one piece with the first dynamic pressure generating element and/or the display device. This can further improve the sealing of the system or can also better prevent particles or cut-outs from entering into the region of the display device. Furthermore, the structure may thereby also become stronger or more stable. In principle, the further dynamic pressure generating element may have the features of the aforementioned "first" dynamic pressure generating element, for example a gap size with respect to the structure, a pendability within the structure, etc.

It is also proposed that the fill level display has a blocking element. The blocking member may trap the collected matter for the dynamic pressure generating member or the supporting portion of the display device. In particular, the blocking element protrudes or surrounds the structure in the region of the bearing point or at least one fluid flow is kept away from the bearing point. Thereby, a continuous rotatability of the dynamic pressure generating element can be ensured. Furthermore, the blocking element can project obliquely or vertically into the collecting device (downwards with respect to the direction of gravity), which, when filling the collecting device, leads to a sudden pressure drop, in particular in the inlet region, as soon as the filling reaches the blocking device, so that the display device swings into the "full" state.

It is furthermore proposed that the dynamic pressure generating element is located in the inlet plane formed by the inlet or at least parallel to the inlet plane in the rest position and in the filling position. Thus, at least little of the collection is kept entering the filling level device, but at the same time the dynamic pressure generating element is not directly subjected to the flow of collection. In a typical horizontal orientation of the level indicator or of the inlet plane, gravity can also act on the dynamic pressure generating element and guide it back into the horizontal position or act on the dynamic pressure element against the dynamic pressure.

Furthermore, the utility model discloses set out from the collecting device who has aforementioned material level display. The fill level indicator has, in particular, a structure which connects an inner collecting volume enclosed by the collecting device with the outside of the collecting device, wherein a pivotable dynamic pressure generating element is arranged in the structure, which dynamic pressure generating element is designed to at least substantially interrupt the gas flow through the structure. The display device is connected to the dynamic pressure generating element in a manner such that the dynamic pressure generating element is movable in the direction of the display device.

It is furthermore proposed that the collecting device, in particular a wall of the collecting device, forms a functional component of the fill level indicator, in particular a wall of the structure. Thereby, the level display and the collecting device are integrally joined to each other, which may save weight, costs and components.

Furthermore, a garden processing machine, in particular a lawn mower, is claimed, comprising the aforementioned level display, in particular comprising a collecting device with the aforementioned level display. In principle, however, the fill level indicator can also be mounted directly on the garden processing machine, for example in a discharge flap or elsewhere.

Detailed Description

Fig. 1 discloses a ground working implement 10 configured as a lawn mower. The ground processing appliance 10 comprises a housing 12 in which a travelling mechanism (not shown) and a mowing mechanism (not shown) are received. The mowing mechanism comprises a cutting element (not shown) which, in operation of the floor-processing appliance 10, serves to cut or cut through cut material, in particular grass, or the like. The four wheels 14 are connected to the running gear. The floor working appliance 10 is designed as an electric floor working appliance 10, but it can equally well be an internal combustion engine-operated floor working appliance 10 or the like. In the present exemplary embodiment, the energy supply of the ground processing appliance 10 is effected either via a mains connection or via an energy storage device, for example a replaceable and/or at least rechargeable battery pack. The at least one electronic component 16 and the electric motor 18 are supplied with energy by an energy supply device. The electronic component 16 is designed for controlling the floor processing appliance 10, in particular for controlling the electric motor 18 of the floor processing appliance 10. The mowing mechanism, and in particular the cutting element of the mowing mechanism, is driven by an electric motor 18. However, other elements can also be driven, for example auxiliary driving drives or the like.

The housing 12 is connected to a guide device 20, by means of which the floor working appliance 10 can be guided by hand, although in principle it can also be designed without a guide device and/or can be operated in particular semi-autonomously or fully autonomously. The guiding device 20 comprises a handle 22 with one or more gripping areas 24. The handle 22 includes one or more switching devices 26 that are electrically connected to the electronic components 16 of the floor working implement 10. The connection may be made, for example, wired or wirelessly. A collecting device 28, in particular a grass collecting device or a collecting container or basket, can be arranged on the housing 12 of the floor processing appliance 10. The collecting device 28 is in particular of foldable design, so that it can be stored and/or transported in a space-saving manner in the folded state. In the deployed state, the collecting device forms a collecting volume, in particular for collecting the cuttings (which are discharged, for example, by a floor processing tool). Furthermore, the collecting device 28 has a display device, referred to as a fill level display 30, which can display the fill level of the collecting device 28. Furthermore, the floor processing appliance 10 comprises an adjustment device 32 for adjusting the cutting height of the floor processing appliance. By means of the adjustment device 32, the distance between the surface to be processed and the mowing mechanism can be adjusted.

Fig. 2 shows the collecting device 28 in a perspective view, the collecting device 28 having a first carrier structure 34 and a second carrier structure 36. The first and second carrying structures 34, 36 constitute first and second side parts of the collecting device 28. Which in the present case is the cover of the collecting device 28 and the second side part is the bottom of the collecting device. For carrying, the collecting device 28 has a handle 38. The handle 38 is in the present case arranged, for example, on the first carrier structure 34. Furthermore, the first carrier structure 34 has, for example, fixing elements 40 for fixing the collecting devices 42 to the carrier structure 34, but these fixing elements can also be shaped in another way. The collecting device 42 is at least air-permeable. Furthermore, the collecting device 42 is flexible. The collecting means is in the present case a fabric or a mesh, preferably made of a flexible material, in particular plastic. However, it may also be made of other materials. The collection device 42 opens between the first and second carrier structures 34, 36. The collecting means 42 together with the carrying structures 34, 36 delimit an interior space or collecting volume 44 of the collecting device 28. In principle, the support structures 34, 36 can also be made of support elements or rods, for example of wire, which form a structure which is provided for delimiting and/or opening the collecting volume 44, in particular in conjunction with the collecting device 42. The collecting device 28 can be connected to the floor processing tool 10, for example, by means of a device 46, in particular a form-locking device, arranged on the first (upper) carrying structure 34, or can be suspended or hung from the floor processing tool. The first support structure 34 has further locking means and/or connection means 48 in order to be able to form a substantially gas-tight connection with the pivotable flap 50 of the floor processing appliance 10 and/or to improve the connection to the floor processing appliance 10. During operation of the floor processing appliance, in particular by the mowing mechanism, a fluid flow is induced which conveys the cuttings through an outlet or discharge channel into the collecting device 28. The collecting device 42 constitutes a resistance to the gas flow, so that a certain dynamic pressure p 1' can be formed in the collecting apparatus. The dynamic pressure p 1' acts on the fill level indicator 30 and causes a displacement of the display element, as explained in more detail below. The level display 30 is preferably arranged in the rear cover region of the collecting device 28 (with respect to the floor processing appliance 10). Here, the "full" state of the collecting device 28 can be detected or detected in advance, since the cuttings typically accumulate first in the rear region (furthest away from the discharge opening of the floor processing appliance 10). However, once the collecting device 28 has been filled to the fill level display 30, the pressure acting on the fill level display 30 from inside the collecting device 28 drops (p1), so that the display device is displaced again (returns to its original position) (see fig. 4 to 7b for this purpose). The pressures P1 and P2 in the region of the inlet and outlet 54, 56 are now at least similar, so that at least no pressure difference Δ P exists which is sufficient to oscillate the pressure generating means.

Fig. 3 shows the collecting device 28 in an exploded view. The components of the fill level indicator 30 according to the invention in the first embodiment can also be seen together with the other components of the collecting device 28. The fill level indicator 30 comprises a structure 52, in particular in the form of a housing. The structure 52 has an inlet 54 and at least one outlet 56a, 56 b. The structure 52 has walls 58a, 58 b. The walls enclose the passages between the inlet and outlet ports 54, 56a, 56 b. The structure 52 forms a chamber. Furthermore, the structure 52 has latching means 60 (here, locking projections and locking recesses) so that it can be connected with the cover of the collecting device 28 by means of said latching means. In this exemplary embodiment, in particular, the collecting device 28 and the cover described here form a functional part of the fill level display 30. I.e., wall 62 constitutes a wall for structure 52. In principle, however, the wall 62 may also be formed inherently, in particular in one piece with the structure 52. Furthermore, the structure 52 has a recess 64a for rotatably or swingably receiving a dynamic pressure generating element 66 or a display device 68. The display device 68 is formed integrally with the dynamic pressure generating element 66. The display device is pivotably connected to the structure 52 by shaft ends 70a, 70 b. The structure 52 has a viewing window 72. The display device 68 may be swung into the window 72. The display device 68 is designed in a planar, in particular roof-shaped and/or partially circular manner and is connected to the dynamic pressure generating element 66 via a side wall 74, in particular, which merges into a support rib 76. Furthermore, the cover of the collecting device 28 has a latching means 78 which is designed to correspond to the latching means 60 of the fill level indicator 30. Furthermore, a guide groove 79 in the carrier structure 34 is visible, which provides a location for the shaft end 70.

Fig. 4 shows a perspective bottom view of the fill level indicator 30, which is received in the cover of the collecting device 28 or the carrier structure 34. Like components in fig. 3 and in fig. 5 and 6 below are numbered identically and are at least partially not separately set forth. Obviously, the inlet 54 is closed by the passive pressure generating element 66. Further, a blocking member 80 is disposed on the dynamic pressure generating element 66, which can shield the cut object from the bearing site or the rotational axis of the dynamic pressure generating element 66 and the display device 68. The blocking element 80 overlaps or protrudes beyond the cover wall 62, which is designed as a functional component of the fill level indicator 30. In the installed state of the fill level indicator 30, the blocking element 80 is oriented obliquely in the direction of the rear end of the collecting device 28, so that no cut is carried into a potentially remaining gap 86 (see fig. 5), to be precise avoiding a bearing point. The projection 82 caused by the guide groove 79 is likewise visible on the carrying structure 34.

Fig. 5 shows the fill level display 30 in a sectional illustration. The level display 30 has a structure 52 with an inlet 54 and an outlet 56 a. Between the inlet 54 and the outlet 56a, a dynamic pressure generating element 66 is arranged that is swingable about a swing axis 90. The direction of oscillation is indicated by the double arrow 84. The dynamic pressure generating member 66 is swingably arranged in the region between the inlet and outlet ports 54, 56 a. The dynamic pressure generating element has a cross-sectional area a which corresponds to the cross-sectional area a of the inlet 54 or to the cross-sectional area a of the structure 52. The cross-sectional area a of the structure 52 is bounded by walls 58a, 58b, 58c, 62. The dynamic pressure generating element 66 at least substantially closes the cross-sectional area a or the inlet 54. Only the gaps 86, 86a are provided between the dynamic pressure generating element 66 and the inlet 54 for enabling a small displacement or oscillation of the dynamic pressure generating element 66 in friction. The size of the gaps 86, 86' is small so that leakage air flow can be kept as low as possible. The gap 86 between the walls 58a, 58b, 58c, 62 is preferably less than 2mm, in particular approximately 1mm, in order to avoid, in particular, also the intrusion of the collected matter into the fill level display 30, in particular to avoid the collected matter penetrating the fill level display 30 or entering into the region of the display device 68. The gap size should ensure a friction-tight clearance fit to avoid pinching between the walls 58a, 58b, 58c, 62 and the dynamic pressure generating element 66. By means of the dynamic pressure generating element, a pressure compensation (air flow) between the inlet 54 and the outlet 56 can be avoided at least to the greatest possible extent, or a pressure difference Δ P between the first pressure P1 'on the side of the inlet 54 and the second pressure P2' on the side of the outlet 56 can be maintained. If there is no pressure difference (p1 equals p2), gravity preferably acts on the flap and swings it into the area of the inlet 54. Conversely, a pressure difference Δ P or P1 'greater than P2' results in a wobble as shown in fig. 6 b. Alternatively, the fill level indicator 30 has a further dynamic pressure generating element 88. The further dynamic pressure generating element may also be arranged between the inlet 54 and, for example, the further outlet 56 b. The relatively large first outlet 56a reliably ensures the atmospheric pressure or the ambient pressure on the back side of the dynamic pressure generating element 66. In the initial state shown, display device 68 overlays another display device 92. The further display device 92 is constituted by the structure 52. Furthermore, the first display device 68 has a first signal color, in particular red, and the further display device 92 can likewise have a signal color, in particular green.

Fig. 6a and 6b show the structure 52 and the dynamic pressure generating elements 66 and the display device 68 mounted therein in a first (initial state) and a second pivoted or first and second state. In the first state, display device 68 is in a rest or "full" state. The pressure difference ap is not sufficient to displace the dynamic pressure generating element 66 and thus the display device 68. Because the visible display device 68 is red, a "full" message is conveyed to the viewer. Whereas in fig. 6b the dynamic pressure generating element 66 and the display device 68 are in the second swing position. Visible by the displacement is a further display device 92. The display device is green and therefore conveys a "not full" message to the observer (traffic light principle). By means of this type of representation, a clear and thus user-friendly display of the fill level is ensured. Furthermore, by at least largely closing the structure 52 by the dynamic pressure generating elements 66, a clear, here binary display is provided. However, it is also conceivable in principle to display an increased leakage flow through the dynamic pressure generating element 66 or next to the dynamic pressure generating element (for example between the dynamic pressure generating element and the walls 58a, 58b, 58c, 62), i.e. an intermediate phase and thus an incrementally changing fill level of the collecting device 28.

Fig. 7a and 7b show an alternative embodiment of the fill level display 30. In one aspect, the wall 62 is constructed integrally with the structure 52. On the other hand, the fill level display 30 has an outlet 56b in the region of the display device 68. It is obvious that any combination of the level display 30 and the wall 62 constructed in one piece or separately from the structure 52 may be in any combination with either the outlet 56a or 56b or only one outlet 56b and should all be encompassed by the present invention. Likewise, fig. 7a, 7b show another dynamic pressure generating element 88. This further dynamic pressure generating element closes the structure 52 with a certain clearance from the wall of the structure 52, similar to the first dynamic pressure generating element 66, and is thus likewise suitable for generating the pressure difference Δ P and/or for ensuring a still better seal between the inlet 54 and the outlet 56 b. Likewise, the other dynamic pressure generating element 88 may be displaceably configured by the pressure difference Δ P between the inlet and outlet 54, 56 b. The dynamic pressure generating element 66 is shown in fig. 7a in a rest or "filled" position. The dynamic pressure generating element is located in the region of the inlet plane through the inlet formation or substantially parallel to the inlet plane.
