Description

The invention relates to a suction device with a nipple housing, in which a suction motor for generating a suction flow and a collecting space for collecting separated from the suction flow particles and / or separate moisture are arranged, and arranged on a housing wall of the nipple housing electrical outlet for connecting a Plug of an electrical device, in particular an electrical tool.

Such a suction device is for example off DE 10 2009 015 642 A1 known. The socket is arranged on a front, upper side of the sucker housing, so that it is easily accessible. However, the socket is exposed in such an arrangement of heavy pollution. Furthermore, the socket can be easily damaged. Frequently, for example, the lid closes when the socket is closed.

A proposal to solve this problem is to arrange a socket on a front of the nipple housing projecting arm, so that it is virtually arranged on a kind of trunk. Such an arrangement is very bulky. The suction device vacuum cleaner is thus less manageable and needs more space when maneuvering.

It is therefore the object of the present invention to propose an improved arrangement of a socket on a suction cup of a suction device.

To solve the problem is provided in a suction device of the type mentioned that the socket is arranged in a recess of the housing wall, so that it is set back completely or substantially behind a front side of the housing wall, in particular in the vicinity of the depression.

By "front" is meant in particular the immediate vicinity of the housing wall around the recess around. It is understood that the front but also have a greater extent and can extend, for example, from a front to a back of the sucker housing.

A basic idea of the invention is that the socket is not exposed exposed in front of the nipple housing or in front of the front side of the housing wall, but on the contrary protected in a recess. The recess is expediently dimensioned such that a plug housing of the plug inserted into the socket is at least substantially received in the recess when the plug is plugged into the socket.

The suction device expediently switches on the suction motor automatically when a current that can be detected by a sensor device of the suction device flows from the electrical device connected to the socket, in particular an electric tool, for example a drilling machine, a saw or the like, via the socket. is consumed. Thus, the suction device so sucks in the operation of the electrical device or tool accumulating dust, chips or the like and also turns off again, expediently after a certain delay time when the electrical device or tool is off or will.

An end face of the socket is inclined with respect to an upper side of the sucker housing with an oblique inclination downwards.

The oblique slope is expediently about 45 ° with respect to a horizontal or a vertical.

A thru-axle, along which the plug can be inserted into the socket, is inclined with respect to a top or bottom of the sucker housing.

Thus, the socket contaminates much less than a tilt upwards. Working in a dusty environment, especially in flammable dusts, is thus better possible.

At this point it should be noted that an insertion of the plug from above, in particular obliquely above, in principle, would also be possible with a recessed and protected on the sucker housing outlet.

The skew angle is, for example, 45 ° with respect to a horizontal or a vertical. It is understood that a steeper plug axis counteracts contamination, while a flatter, more horizontal insertion axis improves operability.

The depression is expediently formed by several conversions, for example an upper wall above the socket, a rear wall, on which the socket is arranged, and a lower wall, which then extends back to the housing wall. Of course, also expediently side walls of the housing wall to the rear wall with the socket.

For example, the top wall is shorter than the bottom wall.

The upper wall extends, for example, parallel to an upper side of the sucker housing or possibly with a slight inclination.

The lower wall, however, is advantageously inclined from the rear wall with the socket to the housing wall down obliquely. For example, if dirt penetrates into the recess, it can slide on the inclined bottom wall back outwards or slip.

The bottom wall and the rear wall are expediently at an angle of about 50-30 ° to each other.

The depression expediently has a narrowing towards the socket.

Advantageously, the socket can be closed with a lid. In principle, the cover could be a plug-in cover or a sliding cover. Preferably, however, is a pivotal mounting of the lid: the lid is suitably by means of a pivot bearing pivotally mounted between an open position in which the socket is accessible, and a closed position, in which the lid closes the socket.

The recess in which the socket is arranged, also has a protective function for the lid. In the unfolded, open state, the lid is not or only slightly before a front side of the housing wall.

It is also possible that in front of the housing wall, an additional projection, such as a ram or another projection, z. B. above, in the middle or in particular in the bottom region of the sucker housing, d. H. So in the area of the bottom of the sucker housing, protruding. Although the lid now protrudes in front of the recess, it may nevertheless be provided with advantage that the lid does not protrude in front of the projection in the open position.

The cover is suitably spring-loaded in the direction of the closed position, for. B. by a leg spring arrangement.

Advantageously, it may be provided that the lid when plugged into the socket on a plug housing of the plug or a cable leading to the plug is applied such that a free, remote from the pivot bearing of the lid portion of the lid is not or only slightly before the front of the housing wall protrudes.

The cover advantageously forms a cover for the plug when it is plugged into the socket. The lid then occupies a covering position.

Advantageously, the lid in this covering position is not or only slightly before the front of the housing wall. If the above-mentioned projection, in particular in the bottom region of the sucker housing, is present, which still protrudes in front of the housing wall, it is advantageous if the cover in the covering position in any case does not protrude from this projection, for example the crash protection.

The pivot bearing of the cover is expediently arranged in the region of an upper side of the depression, so that the cover is pivoted downwards in the direction of the closed position. This also has the advantage that the lid falls down due to gravity. In addition, it can fulfill its function as a cover for the plug optimally when the plug is plugged into the socket.

Furthermore, it is expedient if at least one seal is arranged between the cover under the socket when the cover assumes the closed position. The seal may for example be provided on the lid, on the socket or both components.

The housing wall is expediently arranged a side wall of the sucker housing or on a side wall. The side wall extends from a front side of the nipple housing, to which usually a suction inlet is arranged, to a rear side of the nipple housing.

It is understood that the nipple housing can also be multi-part, d. H. For example, a lower component with the collecting space for the dust, water or the like, as well as in the upper housing component, which may also be referred to as an engine part. In particular, the socket is arranged on the motor part, on which other electrical components are provided.

Furthermore, it is expedient if the socket forms part of a socket module which can be fastened detachably to the housing wall on the basis of fastening means, for example plug-in means or the like. Thus, for example, the socket can also be replaced by a cover, a dummy module or another module when it is not needed. Locking means for fastening the socket module are advantageously provided on the sucker housing.

A depth of the recess is expediently dimensioned so that a plug housing of the plug at least substantially in the Well is recorded when the plug is plugged into the socket. This has the advantage that only the cable or possibly a grommet that surrounds the cable protrudes in front of the housing wall.

The top 25 of the sucker housing 11 is from a top wall 31 of the top 12 formed, which is expediently designed for parking objects. At one between the top wall 31 and the nipple housing lower part 13 or its front wall 26 extending front wall 32 of the top 12 are operating elements 33 , a compressed air connection 34 or the like.

There would also be advantageous, for example, a socket, to which an electrical device, in particular an electrical tool 90 , For example, a grinder, a drill, a saw or the like of other electrical loads can be connected, so that the suction device 10 detects the current flowing through the socket power and the suction motor 14 turns.

At the suction device 10 however, a protected, less exposed arrangement of the socket is made, which is particularly advantageous especially in flammable or explosive environment: a power outlet 35 is in a depression 50 of the sucker housing 11 protected and recessed. A depth of the depression 50 is chosen so that one into the socket 35 plugged in 80 not or only slightly before a front side of the sucker housing 11 at the recess 50 is arranged, protrudes.

The depression 50 is advantageous to the electrical components of the suction device 10 having sucker housing upper part 12 arranged, but also an arrangement on a Saugergehäuse-lower part would be possible.

The depression 50 is on one of the long sides 22 . 23 , submit the long side 23 arranged. At this point it should be noted that of course a recessed or recessed with respect to a housing front side arrangement of a socket on any other side of a nipple housing it would be possible, for example, on a front or back or the like.

The depression 50 has a top wall 51 , a lower wall 52 as well as a back wall 53 on. Continue to run next to the top and bottom wall 51 . 52 each side walls 54 , At the back wall 53 is an opening 55 for a socket housing 37 the socket 35 intended.

The socket housing 37 may be made of a relatively strong and / or rigid material. Preferably, the socket housing 37 a protective and / or sealing function, ie it advantageously protects the inside of the socket housing 37 arranged electrical components, such as electrical contacts, connections to electrical conductors or the like.

In the embodiment, the socket housing 37 in a protective housing 45 arranged, which has a sealing function. You could use the protective housing 45 Also refer to a sealing pot.

The protective housing 45 Conveniently consists of a flexible material, for example flexible plastic, rubber or the like. The protective housing 45 but can also be readily made of a relatively hard material, for example hard plastic. In this case, it is particularly useful if the protective housing 45 provided with a flexible or compliant coating, for example a rubber coating or a plastic coating made of soft plastic.

The upper wall 51 and the top wall 31 of the top 12 run approximately parallel to each other. The bottom wall 52 however, it is inclined at an angle, that is, it runs from the rear wall 53 ago, at the outlet 35 is arranged, inclined obliquely down to the front or to the side wall 30 of the top 12 down to the recess 50 is arranged. Thus, so can in the depression 50 hardly accumulate dirt, moisture or the like. The bottom wall 52 namely forms a drainage slope, such from the depression 50 leads out.

The power outlet 35 is by means of a lid 36 closable. The lid 36 is with the help of a pivot bearing 41 pivotable with respect to the socket housing 37 stored so that it is adjustable between an open position O and a closed position S, in which he has a front side of the socket 35 for plugging in the plug 80 serves, closes.

A front section 38 of the socket housing 37 is located in front of the back wall 53 while a rear section 39 through the opening 55 stuck through it. From the back section 39 leads a connection cable 40 away, with other electrical components inside the sucker housing 11 , For example, a sensor device 70 with a current sensor, one with a power plug 72 provided connection cable 71 the suction device and the like is connected and / or in sensor connection. When the sensor device 70 one to the outlet 35 determines flowing current because there is a consumer connected, for example, an electric hand tool, it switches using switching means 73 the suction engine 14 one. When the current flow ends, the switching means switch 73 the suction engine 14 or the suction turbine, but expediently only after a predetermined follow-up time.

Between the socket housing 37 and the nipple housing 11 are expediently provided seals. This sealing function is in the embodiment of the protective housing 45 provided.

Furthermore, it is advantageous if the connection cable 40 is sealed. For example, the connection cable runs 40 from the socket housing 37 away through a cable section 46 of the protective housing 45 , The connection cable 40 lies close to the interior of the cable section 46 so that the cable section 46 the connection cable 40 tightly encloses.

The cable section 46 of the protective housing 45 again penetrates the holding receptacle 59 at a passage opening 64 , The cable section 46 in turn is sealingly on the inner circumference of the passage opening 64 at.

It would be possible to connect a socket housing directly to a nipple housing, for example, insert, lock, screw or the like.

At the suction device 10 whereas, there is a holder with a holding frame 56 to hold the socket 35 on the sucker housing 11 intended. The support frame 56 has a front wall section 57 on, which is on the sidewall 30 or supported therein a receptacle.

The top wall extends away from the front wall section 51 , The upper wall 51 thus forms a part of the holding frame 56 , Furthermore, the back wall forms 53 a part of the support frame 56 ,

The upper wall 51 runs parallel to a top wall 60 a plug or holding receptacle 59 for the support frame 56 or the socket housing 37 ,

The holding receptacle 59 also has a back wall 61 as well as a lower wall 62 , ie a bottom wall, on. Between the bottom wall 62 the holding receptacle 59 and the bottom wall 52 the depression 50 can be beneficial one step 58 be provided.

The rear section 39 of the socket housing 37 is in a middle section 47 of the protective housing 45 added. Between the middle section 47 and the cable section 46 extends a rear section 48 of the protective housing 45 , The rear section 48 based conveniently at the top of the top wall 60 and at the back of the back wall 61 from or is located on the upper wall 60 or the back wall 61 in the sense of a poetry.

The front section 38 of the socket housing 37 is a sealing cuff 49 of the protective housing 45 assigned.

Conveniently, a portion of the protective housing 45 between the holding frame 56 and the socket housing 37 clamped, which achieves a sealing function. For example, it is expediently collar-like or in the manner of a sealing flange in front of the central, tubular section 47 protruding sealing sleeve 49 between the front section 38 of the socket housing 37 and the support frame 56 For example, the back wall 53 , clamped.

The support frame 56 forms together with the socket housing 37 and / or the protective housing 45 a socket module 63 ,

The support frame 56 is expediently with the sucker housing 11 , so for example, the holding recording 59 jammed and / or locked and / or screwed.

One end face or narrow side of the back wall 53 that form part of the support frame 56 forms, supports itself on a wall of the holding receptacle 59 from, for example, the bottom wall 62 , There is expediently a latch or a plug-in receptacle for the support frame 56 intended.

Conveniently, also the front wall section 57 of the holding frame 56 with the sucker housing 11 latched or jammed.

A particularly good hold of the support frame 56 on the sucker housing 11 is advantageously achieved by a screw. For example, one or more screws 65 between the top wall 51 and the upper wall 60 intended.

The back wall 53 and thus a front side or plug-in end wall 43 the socket 35 and the top wall 31 or the top 25 of the sucker housing 11 are suitably at an angle to each other, for example at an angle of 60-15 °, mainly for example about 45 °.

A thru axle 83 along which the plug 80 into the socket 35 is to insert, has expediently an angle of about 45 ° to the horizontal. Thus, so runs a cable 82 from a connector housing 81 of the plug 80 out to an angle down. Dirt or moisture is therefore not in the direction of the outlet 35 but led away diagonally down.

The arrangement is suitably made so that only a short rear portion of the plug housing 81 , mainly even only a cable grommet, in front of a front side of the sucker housing 11 ie in front of the side wall 30 , projects. This will also unintentional release of the plug 80 from the socket 35 counteracted.

The pivot bearing 41 is located at a top of the well 50 , next to the upper wall 51 , Thus, the lid works 36 from the bottom up towards the open position O on. In the 3 shown open position O hold the lid 36 but not at, but he works alone due to its gravity, expediently due to a spring arrangement, again in the direction of the closed position S, so that a free end 42 for example, the plate-like lid 36 on the plug 80 For example, its connector housing or cable 82 is present and not or only slightly before the side wall 30 protrudes, see in particular 4 , Thus, the lid 36 effectively protected against mechanical damage, especially breakage.

In addition, the lid takes 36 while a covering A, in which he the plug 80 covers and also in this way the penetration of dirt, moisture or the like, counteracts.
