Description

Technical Field

[0001] The present invention relates to a power tool that can be connected to an elongated tool extending forward in a spatial direction, wherein the power tool is designed to drive the tool to perform a rotational and / or impact movement. The power tool includes a dust box for extracting dust-laden air from the working area of ​​the power tool, and dust can be filtered out of the dust-laden air by means of a filter. A virtual center plane can be placed through the body of the power tool and / or the dust box, which divides the body into two halves, wherein the inlet of the dust box for dust-laden air is mainly arranged on one side of the center plane, and the filter of the dust box is mainly arranged on the other side of the center plane. In a second aspect, the present invention relates to a dust box for a power tool, wherein the inlet and the filter of the dust box are present on different sides, that is, in different halves of the dust box. Background Art

[0002] In the field of power tools, in particular in the field of hammer drills, dust boxes are known, which can be connected to the power tool in order to extract dust-laden air from the working area of ​​the power tool. The power tool can be connected to a tool by means of which the work can be performed. In the case of a hammer drill, the hammer drill can be connected to an elongated tool, which can be driven by the device to perform a rotational and / or percussive movement. In the case of so-called "onboard" dust boxes for power tools, two different types of dust boxes are mainly known: Firstly, the following dust boxes are known, in which the suction channel between the working area and the dust box is guided along the tool on one side of the tool of the power tool. Secondly, the following dust boxes are known, in which the suction channel is guided in or near a plane, which includes the working axis and the handle axis of the power tool. Therefore, the plane is preferably also referred to as the "working plane" of the power tool. The working axis corresponds to the axis on which the tool of the power tool is located, wherein the handle axis includes the main handle of the power tool. Dust boxes with laterally directed suction channels generally have good extraction performance, but are generally very large and heavy, so that when connected to such a dust box, the power tool also becomes very large and heavy. This can make the power tool difficult to handle and make working with the power tool laborious and less comfortable. In addition, before transport in a transport box, a power tool with such a dust box generally has to be disassembled so that the power tool and the dust box can be loaded in the transport box. However, such disassembly and loading can take up working time and is therefore undesirable.

[0003] In the case of a dust box in which the suction channel is located in the working plane of the power tool, the filter for filtering dust from the dusty air is usually located on the front wall or rear wall of the dust box. This can disadvantageously lead to dust accumulation on the filter when the power tool is used to work on a substrate (such as a floor) or a ceiling (i.e., a ceiling). This can lead to rapid clogging of the filter, so that, for example, the filter has to be replaced or cleaned only if a small number of holes can be made with the power tool.

[0004] The object on which the invention is based is to overcome the above-mentioned drawbacks and disadvantages of the prior art and to provide a power tool which combines the advantages of the known designs. In particular, the object is to enable the greatest possible number of drill holes to be produced during each use of the power tool before the filter has to be replaced or cleaned. In addition, the object is to make the dust box particularly compact and light in order to provide a light and comfortable power tool. The experts will appreciate that the dust box can be provided with a cost-effective and easily replaceable filter and that the dust box can be particularly leakproof in order to optimally utilize the existing suction performance and without any leakage.

[0005] This object is achieved by the subject matter of the independent claims. Advantageous embodiments related to the subject matter of the independent claims are found in the dependent claims. Summary of the invention

[0006] According to the present invention, a power tool is provided, which can be connected to an elongated tool extending forward in a spatial direction. The power tool is designed to drive the tool to perform rotation and / or impact movement. The power tool includes a dust box and is releasably connected to the dust box, wherein the dust box is designed to extract dust-laden air from the working area of ​​the power tool, and filter dust from the dust-laden air by means of a filter, so that dust can be collected in the internal space of the dust box until the dust box is emptied. A virtual center plane can be placed through the body of the power tool and / or the dust box, and the virtual center plane is designed to divide the body into a first side and a second side in a cross-sectional illustration viewed from the forward spatial direction. In this case, the inlet for dust-laden air of the dust box is mainly arranged on one side of the center plane, and the filter of the dust box is mainly arranged on the other side of the center plane.

[0007] Within the meaning of the present invention, it is preferred that the first side of the main body of the power tool and / or the dust box can be designated as the left side, and the second side of the main body of the power tool and / or the dust box can be designated as the right side. In this case, the main body of the power tool and / or the dust box is preferably observed from the forward spatial direction, which is preferably determined by the position of the tool of the power tool, and the main body of the power tool preferably determines the rear area and the backward spatial direction of the power tool. The main body can be the main body of the power tool, which includes, for example, a motor, an impact mechanism and / or a battery of the power tool. Within the meaning of the present invention, it is also preferred that the main body is the main body of the dust box. Preferably, the virtual center plane conceptually divides the main body of the power tool or the dust box into two sides or two halves.

[0008] Within the meaning of the present invention, it is preferred that the larger part of the inlet of the dust box is arranged on one side of the power tool or its body, while the smaller part of the inlet of the dust box is arranged on the other side of the power tool or its body. Preferably, within the meaning of the present invention, the larger part of the inlet of the dust box can be designated as "the main part of the inlet of the dust box".

[0009] Within the meaning of the present invention, it is preferred that the larger part (i.e. the main part) of the filter is arranged on one side of the power tool or its body, and the smaller part of the filter is arranged on the other side of the power tool or its body, wherein the larger part of the inlet and the larger part of the filter are arranged on opposite sides of the body of the power tool.

[0010] Within the meaning of the present invention, the expression that the "main" part of the object is located on one side of the power tool or the dust box means that preferably the object is located completely or partially on one side or one half of the power tool or the dust box, and if partially on one side or one half of the power tool or the dust box, the larger part of the at least two parts is located on this side or one half of the power tool or the dust box. The expression main part includes the fact that the object is completely arranged on one side or one half of the power tool or the dust box. Within the meaning of the present invention, preferably, the larger part of the at least two parts of the object is arranged on one half of the power tool or the dust box.

[0011] This means that, according to the present invention, preferably, the larger part of the inlet and the smaller part of the filter are arranged on one side of the body of the power tool and / or the dust box, while the larger part of the filter and the smaller part of the inlet are located on the other side (i.e. the opposite side) of the body of the power tool and / or the dust box. The body is divided into two halves by a virtual center plane of the power tool and / or the dust box, which virtual center plane can preferably coincide with the previously described working plane of the power tool. Within the meaning of the present invention, it is preferred that, for example, the tool or the axis of the tool of the power tool is located in the working plane of the power tool. In addition, within the meaning of the present invention, it can be preferred that the virtual center plane of the power tool intersects with the handle of the power tool and the battery of the power tool (in the case where the power tool is a battery-powered power tool) and will be basically divided into two similar or symmetrical halves from the center. The handle of the power tool can preferably be a so-called D handle, which the user of the power tool can grasp in order to grasp the power tool and guide the power tool during operation.

[0012] The invention advantageously makes it possible to produce a particularly large number of drill holes without having to replace or clean the filter. This advantage of the power tool is achieved in particular in all three main use cases of the power tool (working on floors, walls and ceilings on the ceiling), because in none of the three main use cases will the filter be covered with dust and thus not quickly clogged or blocked. Due to the arrangement and design of the dust box, in the main use cases, the dust advantageously falls next to the filter, so that the invention avoids "flooding" or "dusting" of the filter.

[0013] Another advantage of the present invention is that the present invention can provide a particularly compact and lightly designed dust box. This means that the system consisting of the power tool and the dust box can also be designed to be particularly compact and light, and thus the handling of the power tool can be significantly simplified for the user.

[0014] By means of the invention, the dust-laden air from the inlet of the dust box can first flow or be sucked into the interior of the dust box, where some dust is separated from the air flow and placed on the bottom of the dust box. The air continues to flow through the filter, wherein the dust box comprises a suction unit for generating the air flow, wherein in the proposed arrangement of the dust box in the power tool, the air flow finally flows through the suction unit. At this point, the air flow is already substantially dust-free, because dust has been deposited in the dust box or dust has been filtered out of the air flow by the filter. In particular, the proposed arrangement of the dust box in the power tool can achieve particularly good extraction performance. Within the meaning of the invention, the proposed arrangement of the dust box on the power tool is referred to as "asymmetric". Preferably, within the meaning of the present invention, the proposed dust box of the power tool is preferably referred to as an "asymmetric dust box", wherein the asymmetric arrangement of the components of the dust box is characterized in that the inlet of the dust box is mainly arranged on one side of the power tool and / or the body of the dust box, while the filter of the dust box is mainly arranged on the other side or opposite side of the body of the power tool and / or the dust box. In particular, the effect achieved by the asymmetric arrangement of the dust box is that the filter of the dust box is not covered with dust in any of the three main use situations of the power tool (working on the floor, the wall and the ceiling on the ceiling).

[0015] This enables the power tool to drill a large number of holes without having to clean or replace the filter of the dust box. In this way, the operating efficiency of the proposed power tool can be significantly improved.

[0016] Within the meaning of the present invention, preferably, the dust-laden air can be guided from the working area through a suction channel to the inlet of the dust box, the virtual center plane extending through the suction channel. In other words, the suction channel is centrally located in the power tool or in the dust box, which is indicated by the fact that the virtual center plane intersects the suction channel and conceptually divides it into two substantially symmetrical halves. Therefore, the advantages associated with the dust box can also be achieved by the present invention, wherein the suction channel is centrally arranged around the virtual center plane of the body. In particular, this includes a compact design, which allows good and easy handling of the power tool.

[0017] Within the meaning of the invention, it is preferred that the suction channel is telescopic. Thus, the suction channel can advantageously be adapted to different tool lengths of the power tool or to different desired depths of the drilled hole.

[0018] Within the meaning of the invention, it is preferred that the power tool has a first seal which is designed to guide the dust-laden air into the dust box. Preferably, this first seal is present in the region of the inlet of the dust box.

[0019] Within the meaning of the invention, it is preferred that the dust box has a second seal which is designed to guide the purified air from the filter to the suction unit of the dust box. Preferably, the second seal is present in the upper region of the dust box.

[0020] Within the meaning of the invention, it is preferred that the power tool has a first seal for guiding dust-laden air into the dust box and a second seal for guiding purified air from the filter to the suction unit of the dust box, the first seal and the second seal being oriented in substantially the same spatial direction. Within the meaning of the invention, this preferably means that the first seal and the second seal are substantially parallel and point substantially in the same spatial direction. The terms "substantially parallel" or "substantially in the same spatial direction" do not constitute unclear terms for a person skilled in the art, since they know that, for example, the term "substantially parallel" can include small deviations from exact mathematical parallelism, wherein such small deviations can be, for example, within a range of + / - 5 degrees relative to exact mathematical parallelism.

[0021] It is particularly preferred within the meaning of the invention that the first seal and the second seal are arranged at the same height within the power tool or within the dust box. In this way, the seal can be produced particularly cost-effectively. In addition, it has been shown that the seal arranged in the described manner is particularly tight and has a good sealing effect while being inexpensive. As a result, the existing suction performance of the dust box suction unit can be used particularly well and undesired leakage is effectively prevented.

[0022] Furthermore, the air guide element can be formed integrally in this way, so that, in any case, the good sealing effect of the seal of the dust box can be further improved. Therefore, within the meaning of the present invention, it is preferred that the dust box has an air guide element, which is formed integrally. The air guide element can be designed as an air guide plate, for example. However, within the meaning of the present invention, it can also be preferred that the air guide element comprises plastic or is formed from plastic. The air guide element can have a perforated bottom, through which the air flow can enter the air inlet chamber of the suction unit of the dust box.

[0023] Within the meaning of the invention, it is preferred that the dust box has a third seal which is designed to seal an upper region of the dust box relative to a lower region of the dust box.

[0024] Within the meaning of the invention, it is preferred that at least one of these seals is integrated in the filter frame of the dust box. Within the meaning of the invention, it is preferred that two seals and particularly preferably all three seals are integrated in the filter frame of the dust box. By integrating the seals in the filter frame, the seals of the dust box are regularly replaced and thus, by the invention, a "good as new" sealing effect of the seals of the dust box can be ensured overall. It has been shown that regular replacement of the seals of the dust box can advantageously significantly extend the service life of the dust box.

[0025] Preferably, a filter consisting of folded filter paper is used in the dust box. The filter designed in this way preferably has lamellae through which the air flow to be cleaned passes. Preferably, within the meaning of the present invention, such a filter can be referred to as a lamellae filter. By means of the proposed arrangement of the filter in the dust box, it can be advantageously ensured that the direct path or the shortest connection from the inlet of the dust box in the direction of the filter extends substantially parallel to the normal direction of the lamellae of the filter. This advantageously results in the fact that in this way, the initially dusty air flow is substantially only in direct contact with the outer lamellae of the filter and therefore only may contaminate and clog these lamellae. In order to reach the inner lamellae, within the meaning of the present invention, it is preferred that the air flow is diverted several times. This can reduce the dust load of the air flow so that the air is filtered. In particular, this avoids the internal filter layer of the filter from being contaminated and clogged. Within the meaning of the present invention, it is preferred that the filter is designed as a lamellae filter, wherein the direct path and / or the shortest connection through the dust box substantially vertically hits the lamellae of the lamellae filter.

[0026] It has been shown that by designing the filter as a lamella filter and by directing the air flow through the dust box, it is possible to use a filter with fewer lamellae, such as in conventional dust boxes known from the prior art. This means that the filter can be designed to be particularly compact and space-saving, and the dust box can remain compact as a whole. In addition, the manufacturing costs of the filter can be reduced by reducing the number of lamellae. In addition, it has been shown that the proposed arrangement and design of the filter can have a positive influence on the air flow, because a particularly large contact area is provided between the filter and the air flow.

[0027] In a second aspect, the invention relates to a dust box for the proposed power tool, wherein the dust box is designed to extract dust-laden air from the working area of ​​the power tool and to filter dust from the dust-laden air by means of a filter, so that dust can be collected in the inner space of the dust box until the dust box is emptied. A virtual center plane can be placed through the dust box, which virtual center plane is designed to divide the dust box into a first side and a second side in a cross-sectional illustration viewed from the forward spatial direction, wherein the inlet of the dust box for the dust-laden air is mainly arranged on one side of the dust box, and the filter of the dust box is mainly arranged on the other side of the dust box. The terms, definitions and technical advantages introduced for the power tool preferably also apply to the dust box.

[0028] Preferably, the virtual central axis divides the dust box or its body into two halves, which are preferably designated as a first half and a second half of the dust box.Preferably, the halves of the dust box are substantially the same or similar in size.

[0029] Within the meaning of the invention, preferably, a first side of the dust box can be designated as the left side and a second side of the dust box can be designated as the right side. In this case, the dust box is viewed from the forward spatial direction, wherein the front side or the forward spatial direction of the dust box is preferably determined by the position of the filter and the rear side or the rearward spatial direction of the dust box is determined by the position of the inlet for the dust-laden air.

[0030] Within the meaning of the present invention, it is preferred that the larger part of the inlet of the dust box is arranged on one side of the dust box, while the smaller part of the inlet of the dust box is arranged on the other side of the dust box. Within the meaning of the present invention, it is further preferred that the larger part (i.e. the main part) of the filter is arranged on one side of the dust box, while the smaller part of the filter is arranged on the other side of the dust box, wherein the larger part of the inlet and the larger part of the filter are arranged on opposite sides of the dust box, respectively.

[0031] Within the meaning of the invention, it is preferred that at least one seal of the dust box is integrated in the filter frame of the dust box. In addition, within the meaning of the invention, it can be preferred that the filter is designed as a lamella filter, wherein the air flow through the dust box impinges essentially vertically on the lamellae of the lamella filter.

[0032] Additional advantages will become apparent from the following description of the drawings. The drawings, descriptions and claims contain many combined features. Those skilled in the art will also conveniently consider these features individually and combine these features to form other reasonable combinations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] Figure 1 A front view of a preferred configuration of a dust box 50 is shown with a virtual center plane 20. Figure 1 As shown, the virtual center plane 20 divides the dust box 50 into two halves 22, 24 of substantially equal or similar size. Figure 1 The first or left half 22 in the exemplary embodiment shown comprises the main portion of the filter 52 of the dust box 50, while the second or right half 24 of the dust box 50 comprises the filter 52 for the dust-laden air 14 (see Figure 5 ) of the main part of the inlet 56 of the dust box 50. The dust box 50 has an inner area 54, wherein the inner area 54 of the dust box 50 preferably acts as a dust container. The inner area 54 of the dust box 50 or the dust box 50 can be divided into an upper area 66 and a lower area 68 by the third seal 34. The filter 52 of the dust box 50 is preferably formed by a sheet filter having a sheet 64.

[0036] Dust-laden air 14 is sucked into the power tool 10 (see Figure 3 ) of the operating area 16 (see Figure 4) and is conveyed via the suction channel 26 in the direction of the inlet 56 of the dust box 50. The dust-laden air 14 passes through the inlet 56 and thus enters the interior 54 of the dust box 50, where the main part of the dust is deposited on the bottom or the deepest part of the dust box 50, depending on the working direction. The air flow is sucked through the adjacent filter 52 in the direction of the suction unit 58. From here, the air passes through the perforated bottom of the air guide element 60 into the air intake chamber of the fan 58. After the air from the suction unit 58 has reached an increased pressure level, it flows out of the dust box 50 through the outlet slot.

[0037] Figure 1 Also shown are a first seal 30 and a second seal 32. The first seal 30 is represented by a white block, while the second seal 32 is represented by a black block. Figure 1 A filter frame 62 is depicted, into which the seals 30 , 32 , 34 may be integrated.

[0038] Figure 2 A diagram showing a preferred configuration of a dust box 50 with a suction channel 26 and a dust container 54 is shown. Figure 2 The perforations 72 in the region of the inlet region 56 of the dust box 50 are shown, and the filter frame 62 is also shown.

[0039] Figure 3 A schematic illustration of a preferred configuration of a power tool 10 and the definition of a virtual center plane 20 is shown. The virtual center plane 20 is preferably defined by a first axis A and a second axis B. The first axis A is preferably the rotation axis and / or impact axis of the power tool 10. The second axis B is preferably the motor axis or the main handle axis of the power tool 10. The first axis A and the second axis B are preferably perpendicular to each other and thus define the virtual center plane 20.

[0040] Figure 4 A schematic illustration of a preferred arrangement of a power tool 10 and a dust box 50 is shown. Figure 4 The tool 12, handle 28, suction channel 26 and working area 16 of the power tool 10 are shown. Figure 4The third axis C, which in the exemplary embodiment of the invention shown extends substantially parallel to the first axis A of the power tool 10, preferably extends through the suction channel 26. The first axis A and the third axis C extend substantially perpendicularly to the second axis B. The dust-laden air 14 is sucked from the working area 16 of the power tool 10 through the suction channel 26 in the direction of the dust box 10. The reason for this is the suction unit 58 of the dust box 50, which generates a negative pressure and thus a suction flow. The suction channel 26 has a flow cross section SQ through which the dust-laden air 14 flows in the direction of the dust box 50. The axis C, which preferably extends through the suction channel 26 in the middle or centrally, is preferably perpendicular to the flow cross section SQ of the suction channel 26. Within the meaning of the invention, it is preferred that the dust-laden air 14 flows along the third axis C, so that the flow direction of the dust-laden air and the third axis C extend substantially parallel to each other or in a colinear relationship. Within the meaning of the invention, it is preferred that the second axis B extends through the motor 36 of the power tool 10. Alternatively, the second axis B preferably extends through a handle 28 of the power tool 10. Preferably, this handle 28 may be in the form of a so-called pistol handle.

[0041] Figure 4 A preferred configuration of the dust box 50 is also shown. The dust box 50 has a lower region 68 with an inlet 56, a filter 52 and an outlet 70, and an upper region 66. Dust-laden air enters the dust box 50 from the suction channel 26 of the power tool 10 via the inlet 56. Here, some dust can accumulate in the lowest region of the dust box 50, where the air is further sucked in the direction of the suction unit 58 due to the negative pressure generated by the suction unit 58, or flows here. In this case, the air passes through a transition region between the lower region 68 and the upper region 66 of the dust box 50, wherein the filter 52 is arranged in this transition region. The filter 52 is designed to filter the dust-laden air so that, in particular, low-dust air or filtered air enters the upper region 66 of the dust box 50.

[0042] The dust box 50 may have different seals 30, 32, 34, the first seal 30 being designed to guide the dust-laden air 14 into the dust box 50. The second seal 32 may be used to guide the cleaned air from the filter 52 to the suction unit 58 or fan 58 of the dust box 50. The third seal 34 is designed to divide the dust box 50 into an upper area 66 and a lower area 68 (see Figures 4 to 7). The lower region 68 of the dust box 50 comprises an inlet 56 and an outlet 70 of the dust box 50, wherein the filter 52 is arranged in the region of the outlet 70. The filter 52 represents the transition between the lower region 68 and the upper region 66 of the dust box 50, wherein dust-laden air is present in the lower region 68 and low-dust air is present in the upper region 66. The filter 52 is preferably designed as a lamella filter with lamellae 64 and is designed to filter dust out of the air flow. This reduces the dust load of the air when the air passes through the filter 52 or during the transition from the lower region 68 to the upper region 66 of the dust box 50.

[0043] Figure 5 A schematic illustration of a preferred arrangement of a power tool 10 with a dust box 50 and also of its inlet region 56 and outlet region 70 is shown. Figure 5 The left side of the power tool 10 shows a preferred configuration, which includes a tool 12, a handle 28 and a suction channel 26. In the working area 16 of the power tool 10, a substrate (not shown) can be processed, wherein dust and dirt are generated during this processing and can be extracted using a dust box 50.

[0044] Figure 5 The upper right side of shows a section through the power tool 10. The cross-sectional illustration shows the power tool 10 and the dust box 50 below it in the upper region. The dust box 50 is divided into an upper region 66 and a lower region 68, wherein the filter 52 of the dust box 50 is arranged between the upper region 66 and the lower region 68. In addition, a third seal 34 can be provided in the transition region between the lower region 68 and the upper region 66 of the dust box 50, which seals the regions 66, 68 of the dust box 50 relative to each other. The third seal 34 is provided so that the region 68 of the dust box 50 (the region where the dusty air is located) can be sealed relative to the region 66 of the dust box 50 (the region where the low-dust air is located).

[0045] Figure 5Also shown is an imaginary plane 20, which divides the dust box 50 and the power tool 10 into a first half 22 and a second half 24. The main part of the filter 52 of the dust box 52 is preferably located in the first half 22, while the main part of the inlet area 56 of the dust box is arranged in the second half 24. The inlet area 56 of the dust box has a flow or inlet cross section, which can have a first centroid SP1. For example, if the inlet cross section is rectangular, the first centroid SP1 can correspond to the intersection of the diagonals of the inlet cross section, for example. The inlet area 56 and its first centroid SP1 are preferably present in the first half 22 of the power tool 10 or the dust box 50. The second centroid SP2 of the outlet area 70 of the dust box 50 can be defined in a similar manner, wherein the outlet area 70 and its second centroid SP2 are preferably located in the second half 24 of the power tool 10 or the dust box 50.

[0046] exist Figure 5 At the lower right side of the power tool 10, another cross section through the power tool 10 is shown, which illustrates the transition area between the lower area 68 and the upper area 66 of the dust box 50. The filter 52 and the third seal 34 of the dust box 50 can be arranged in the transition area. In particular, Figure 5 The lower right side of FIG. 5 shows the arrangement of the inlet area 56 and the outlet area 70 of the dust box 50 on different sides 22, 24 of the dust box 50. The inlet area 56 and the first centroid SP1 of the dust box 50 are present on the first side 22 of the virtual center plane 20, while the outlet area 70 and the second centroid SP2 of the dust box 50 are present on the second side 24 of the virtual center plane 20.

[0047] Figure 6 Another schematic illustration of a preferred configuration of a power tool 10 with a dust box 50 and also its inlet area 56 and outlet area 70 is shown. In particular, Figure 6 The lower region 68 of the dust box 50 is shown to illustrate the location of the inlet region 56 and the first centroid SP1 and the location of the outlet region 70 and the second centroid SP2. Figure 6 A third seal 34 is shown, which may represent a sealing plane for sealing the upper region 66 and the lower region 68 of the dust box 50 from one another.
