Description

waste collectors

The invention firstly relates to a waste collector with a waste collector housing and an opening part, wherein the opening part automatically opens due to a sensor as it approaches the waste collector, whereby a control system evaluating the sensor signals and influencing the motor is provided and the opening part by means of a spring is loaded in the closed position.

Waste collectors of the type in question are known. These have a sensor that monitors the area in front of the opening part. The penetration of an object or a person into this area is detected by the sensor, which results in the electromotive opening operation of the opening part. Such waste collectors are preferably used in the household or commercial sector, more preferably in the restaurant sector. An exemplary solution is shown in US 4,981,275. This has a waste collector housing, in which an inner bucket is insertable like a box. The flap-like opening part is part of the inner bucket covering the housing section of the waste bin, in which housing portion inside the acting on the flap-like opening part electric motor is arranged.

In view of the prior art described above, a technical problem of the invention is seen in designing a refuse collector of the type in question in a manner that is advantageous in terms of use.

This problem is initially and essentially solved by the subject matter of claim 1, wherein it is geared to the fact that the engine is externally placed on the waste collector housing. According to this arrangement, the engine is positioned outside the dumping area of the garbage collector; therefore outside the dirt area. Also, this external arrangement proves advantageous in terms of any care or repair services on the electric motor. Furthermore, the motor may optionally be installed together with an accumulator feeding the motor in a separate housing applied externally to the refuse collector housing, so that it is also protected from contamination and shock when lying outside.

The subjects of the further claims are explained below in relation to the subject matter of claim 1, but may also be significant in their independent formulation.

Thus, it is advantageously provided that, assigned to the opening part of the designed as a proximity sensor sensor is arranged, which detects a space that is to the - in vertical extension - opposite

Wall area of the waste collector extends. As a result of this embodiment, the space is monitored directly above the waste collector, more preferably directly above a filling opening of the waste collector. In this case, it is further preferred not necessarily to detect an approximately horizontally extending region above the refuse collector, but rather, starting from the sensor, a preferably funnel-like opening or club-shaped space. In this case, the sensor preferably detects a space which extends only insignificantly beyond the floor plan of the refuse collector, so that persons or pets passing through the refuse collector do not trigger a faulty opening. The supervised space extends in a projection on a floor or the like, starting from a wall section of the waste collector, the floor plan across to the opposite wall area. Optionally, the monitored space also extends beyond this opposite wall area, but only to a degree which excludes malfunctions, for example by passing people. Accordingly, this extent can extend over the opposite wall section in a range of a few centimeters, up to 20 cm. However, a person is detected who stands directly in front of the waste collector and thus indicates the intended use. The spatially limited access or action area above or in front of the opening part is monitored.

The invention further relates to a refuse collector according to the features of the preamble of claim 1, wherein further the refuse collector has an upper dome in which, forming a segment, flap-like opening part is received, which is pivotable about a horizontal axis.

Also, such a waste collector is known from the aforementioned US 4,981,275.

In order to make such a waste collector more advantageous for use in terms of use, it is proposed that the sensor designed as a proximity sensor, which covers a space which extends only insignificantly beyond the floor plan of the refuse collector, be arranged. Accordingly, according to the invention, an access space is first monitored within a projection onto a floor or the like, so more preferably the immediate area in front of the opening part. However, the space may extend beyond the waste collector floor plan, but only to an extent that precludes malfunctioning, for example, by passing persons or pets. This extension measure over the opposite wall section can be in a range of a few centimeters, up to 20 cm. However, a person is detected who stands directly in front of the waste collector and thus indicates the intended use. The spatially limited access or action area in front of the opening part is monitored. The subjects of the further claims are explained below with reference to the subjects of claims 1 and / or 4, but may also be significant in their independent formulation.

Thus, it is further provided that the sensor detects a space extending from the sensor upwards and with increasing height to the front. According to this embodiment, a waste collector is created, which automatically supported by electric motor opens already when an object or a person approaches this. It is preferably a space detected, which extends starting from the sensor funnel-shaped upwards, or club-shaped. The space covered by the sensor is limited in both horizontal and vertical extent so that further objects positioned at the usual distance from the waste collector are not detected by the sensor, which would lead to irritation in the case of a sensor detection when the waste collector is positioned normally , As further useful advantage proves to be an embodiment in which the sensor interrogates an area that widens above the waste collector and with increasing height beyond the radius of the waste bin addition. At a conventional height of a waste collector between 0.5 and 1.5 meters, the sensor-detected area in the vertical direction preferably extends to a height of about 2 meters, so that a targeted control of the waste bin by a person is certainly detected. The radial extent of the sensor-monitored area is chosen so that a targeted approach to the waste bin triggers the opening movement obliquely from above. Again, however, the radius is so small that objects in the vicinity of the refuse collector or persons or pets passing through the refuse collector do not trigger a sensor signal to open the refuse collector. The sensitivity of the infrared sensor is adjusted to the local conditions adjustable. The opening part is preferably spring-loaded in the closing direction in a known manner. To counteract this spring force in the open state, it is provided that the motor in this open state of the opening part is switched to a generator mode, so further preferably by shorting the electric motor. The resistance generated by the generator operation holds the opening part in the open position until the generator operation is canceled. Alternatively, the electric motor is switched in the open position of the opening part in a pulse mode to hold by pulse-like opening movements, the opening part against the spring force of the return spring. Another advantageous solution provides that the opening part remains open as long as the sensor detects a person or an object. Thus, for example, a person posted in front of the waste collector can successively insert objects into the opened waste collector several times without the opening part temporarily closing. This can be achieved, for example, by a radial widening of the monitored area, which radial widening is activated only when a first sensor signal has generated the opening pulse. Thus, it is precluded that the waste collector passing people trigger an opening. It can also be provided in this regard that starting from a point in time at which a person or an object is no longer detected by the sensor, the opening part remains in the open position for a further, predetermined period of time, so preferably over a period of 2 to 15 seconds, more preferably about 5 seconds. To close the opening part of the generator operation triggering short circuit or the pulse operation can be canceled in the simplest way, after which the opening part moves back spring loaded. In order to actively support this closing movement, it is provided in one embodiment that, at the end of the predetermined period of time, the motor is switched over from generator operation or pulse operation to engine operation and is acted upon to close the opening part. Accordingly, the motor is driven in the opposite direction to the opening operation direction. If the electric motor is used both for the opening and the closing operation of the opening part, a spring loading of the opening part in the closing direction can be used. len. The control is preferably realized as a freely programmed control of a microprocessor. In addition, two sensors may be provided, one example, an object or a person, in particular the hand of a person detected in the vicinity of the waste collector and then opens the opening part, while a second sensor detects whether a user is still in the vicinity of the waste bin and then causes the closing of the opening part in the negative case. Preferably, the second sensor is activated only after the first sensor has generated an opening pulse. With regard to the action of the electric motor on the opening part, various mechanical solutions are conceivable. For example, it is provided that the motor acts with a pinion on a toothed rack, which is articulated on the opening part. The engine is here, as also preferred in the embodiments further below, a servomotor with predefined angle of action between the two end positions. Thus, both the open position and the closed position of the opening part are defined by the predetermined angle of action of the electric motor. Alternatively, both in the open position and in the closed position of the opening part, a stop limit can be provided and the current increase occurring in this case can be evaluated by a corresponding electronics, which in turn causes the switching off of the electric motor. Alternatively, the motor can act on the opening part via a Bowden cable. Here, and also in the previously described pinion-rack configuration, the electric motor acts both in the opening direction of the opening part and in its closing direction. Also, the motor can act on the opening part via a cable, wherein in this embodiment, the motor performs only the opening movement of the opening part. The closing movement is based on the restoring force of the spring acting on the opening part, the electric motor being de-energized in the course of the return movement and allowing the cable to be cut to length. Further alternatively, the motor can act on the opening part via a rod with an eccentric drive. In addition, it is alternatively suggested that the Motor acts on the opening part via a worm drive. For example, the electric motor can set a worm spindle in rotation, in the worm gear engages a projecting from the opening part pin. Due to the rotation of the pin of the opening part is displaced linearly parallel to the screw axis, which leads to a pivoting movement of the opening part. The worm drive can be designed to be self-locking, in particular by selecting a suitable pitch. As a further advantageous embodiment, in which the sensor is an infrared sensor proves to be. Alternatively, the sensor may also be based on generation of an electrostatic field whose disturbance is detected. The corpus of the garbage collector acts as a second sensor, which builds up an electromagnetic field. Thus, a near-person postured by disturbance of the field is detected. In addition, the removal of the person from the field is registered, after which the controller generates the command to close the opening part. Thus, the user can end the disposal process independently of a fixed time control. With regard to the signal transmission can be provided that the electric motor can be controlled by radio. Consequently, can be dispensed with a cable connection between the electric motor and sensor or control. The motor and the intended control and the sensor are preferably fed via a battery or via an accumulator. Alternatively, the power can also be over

Power supply done. In a further embodiment, it is provided that the sensor is integrated in a housing which also accommodates the motor, wherein, more preferably, this housing is designed at least partially following a dome curvature. As a result, in a preferred embodiment, the sensor is placed near the throw-in area. The power supply of the motor can take place with the interposition of a transformer or the like via a laxative laxative power supply cable for direct supply from the house power network. However, preference is given to a self-sufficient design of the waste collector, for which purpose it is provided in a preferred embodiment that the housing for supplying power to the motor is a would have for a battery. This recording is evident by the user, such as changing the accumulator. Alternatively, the receptacle may also have an electrical plug connection for recharging the accumulator by means of a conventional, mains-powered charger. In a preferred embodiment, the housing is accommodated in adaptation to the dome curvature in a dome opening. Accordingly, the housing can be formed such that no or no substantial application to the dome formed by the waste collector is achieved by the housing. Instead, the housing or the housing part which is visible from the outside fits into the dome contour. The components accommodated in the housing, such as the motor or the receptacle for an accumulator, protrude through the dome opening into the interior of the dome, and are accordingly placed in a concealed position. The dome opening is further preferably formed in the region diametrically opposite the opening part. According to this arrangement, the housing placed in the dome opening is placed backwards of the opening part and, correspondingly, facing away from the usual operating side of the waste collector. In addition, it proves to be advantageous that an electrical on-off switch is provided, by means of which the power supply of the motor and the provided electrical or electronic Bauele- elements, such as the sensor and the transmitter, can be interrupted. This switch is more preferably not placed in the immediate access area to the waste collector, but in a region facing away from this, such as in the opening part rearwardly associated collector area. As a result, an accidental operation of the switch is prevented. In a preferred arrangement, the on-off switch is housed in the housing, which also accommodates the motor and, where appropriate, the accumulator.

The waste collector 1 shown in various embodiments in FIGS. 1 to 18 has a waste collector housing 2, which is slipped over an inner bucket 3 in concentric orientation. The lower edge 4 of Housing 2 is comprised of a rubber collar or plastic stand collar 5.

The area of the housing 2 spanning the inner bucket 3 is designed as a dome 6, with a dome base which extends at a small vertical distance from the upper free edge 7 of the inner bucket 3. The dome 6 has an insertion opening 8. Its edge 9 lies on a secant plane of the dome 6.

The insertion opening 8 can be closed by an opening part 10 divided into two parts in this exemplary embodiment. This is composed of two mutually identical cover parts 11 in the form of ball-eighth sections. The cover surfaces of the cover parts 11 project beyond the secant plane of the insertion opening 8 and supplement the dome 6 to a dome-shaped head.

The two cover parts 11 are pivotable about a common, horizontally oriented axis x. For this purpose, the housing side in a cylindrical portion between the housing-side dome portion 12 and the upper edge 7 of the inner bucket 3 cross, horizontally aligned Rand- ringesl3 placed pins 14 are provided which pass through the ball eighth sections of the cover parts 11 in the tip region. Accordingly, the axis x passes through the pin 14th

The two cover parts 11 abut in a transverse joint 15 in the transverse center plane to the pivot plane.

Assigned to a joint side, that is to say assigned to a pin 14, a substantially T-shaped slide 16 is disposed on the housing side in a vertically displaceable manner. This passes through a cross-section adapted opening 17th the edge ring 13 and extends corresponding to the underside of the edge ring 13 between the housing wall and the inner bucket. 3

The vertically oriented T-bar 18 has a longitudinal slot extending in the middle, slot 31, which terminates open to the T-legs 19 toward the end and receives the associated pin 14. The latter accordingly provides a guide for the slider 16.

The substantially perpendicular to the T-bar 18 projecting T-leg 19 carry in the region of their free ends in the direction of the dome interior facing trailing pin 20. These dive in formed in the respective tip region of a ball eighth section of the lid parts 11 longitudinal slots 21, for shaping a pin / slot engagement 22.

The two cover parts 11 are spring-loaded in the closing direction. This is achieved by a in the the slider 16 opposite the tip portion of the ball eighth sections extending, reaching over the closing joint 15 tension spring 23 whose ends are fixed to pin portions 24 of the lid parts 11.

The lid parts 11 are each equipped with an angled 25. With these, the lid parts 11 occur in the closing joint 15 against each other. These bends 25 eliminate the risk of injury and stabilize the thin ball-eighthose sections.

The dome 6 or the housing-side dome section 12 engages over the end edge of the housing 2 defined by the edge ring 13. The self-tapping screws or the like, which are not illustrated in more detail, are used for fixing purposes. The opening of the waste bin, that is, the pivoting of the lid parts 11 in the open position is carried out automatically by electromotive assistance. For this purpose, an electric motor 26 is provided, which is accommodated in a separate housing 27. At the same time, this separate housing 27 accommodates a rechargeable battery 28 (not shown) for supplying the electric motor 26.

The separate housing 27 and thus also the electric motor 26 is externally placed on the waste collector housing 2, assigned to the slider 16 having the hinge region of the lid parts 11th

The interaction between the electric motor 26 and the opening movement of the cover parts 11 compelling slide 16 is solved differently. In the first exemplary embodiment illustrated in FIGS. 1 to 11, the electric motor 26 acts with a pinion 29 on a toothed rack 30. The latter is integrally formed from the slider 16, specifically from the below the slot 31 is further vertically extending T-bar 18, which web portion is included in the cooperation area with the pinion 29 of a housing-side guide 32. The pinion 29 passes through an associated, window-like opening 33 of the housing 2.

The electric motor 26 can act directly on the pinion 29. The arrangement and interaction of electric motor 26 and pinion 29 are shown only schematically in the illustrations. It is conceivable between these also a Über- or reduction.

The signal for opening or closing the waste collector 1 is generated by a sensor 34. This is placed in the region of the motor-side facing housing-side dome portion 12 near the insertion opening 8 and is designed as a proximity sensor. Integrated is the sensor 34 in the same time the electric motor 26 and the accumulator 28 receiving housing 27, which extends from a box-shaped in the cylindrical portion of the waste collector housing 2 section of the dome curvature to near the insertion opening 8. In the free end region of the housing 27, the sensor 34, which usually consists of a transmitting / receiving unit, supported. Although the sensor 34 is shown outboard in the illustrations, it is preferably provided to provide it in a recessed arrangement with respect to the receiving area, thereby providing shock protection. The Absenkmaß here is chosen so low that thereby the space to be monitored by the sensor 34 is not limited. The sensor 34 detects a space that extends from the sensor 34 upwards and with increasing height also to the front, so that there is a queried area B, which is above the waste collector 1 and with increasing height over the radius of the waste collector 1, albeit only marginally expanded. According to the sensor 34, a club-shaped, invisible infrared field is constructed above the insertion opening 8.

The sensor signal is evaluated by a controller, not shown. This control is preferably realized as a freely programmed control of a microprocessor and serves for influencing control of the electric motor 26.

Not shown, but certainly provided on the housing 27 an on-off switch placed to interrupt the power supply for the electric motor 26 and the provided electronics and the sensor 34th

Upon detection of an object or a person in the sensor-monitored area above the opening part 10, the electric motor is acted upon in the opening direction of rotation, which causes a vertical displacement of the slider 16 downwards via the pinion / rack arrangement. Concurrently relocate the T-leg 19 with its trailing pin 20 vertically down under pivotal movement of the lid parts 11 via the pin / slot engagements 22. The Deckelteilverschwenkung takes place against the force of the tension spring 23rd

The cover parts 11 designed in the form of ball eighth sections pivot in this case from their position projecting beyond the secant plane behind the housing-side dome section 12 in the downward direction and thereby form a large-sized filling opening 8.

The swivel open position of the lid parts 11 is stop-limited. The thereby increasing current is detected by the controller, after which the electric motor 26 is switched to a pulse mode for holding the open position against the force of the tensioned tension spring 23. Alternatively, the electric motor can also be switched in the open state of the opening part 10 in a generator mode. It is essential that the electric motor 26 holds the opening part 10 against the force of the tension spring 23 in the open position.

The cover parts 11 are held in the open position as long as the sensor 34 detects a person or an object in the monitored area. It is also preferred that the controller is designed so that from a

Time at which a person or an object is no longer detected by the sensor 34, the opening part 10 still remains for a further, predetermined period of, for example, five seconds in the open position.

After the end of the predetermined period of time, the electric motor 26 is switched back into the engine operation in the closing direction by the control, according to which the slide 16 is displaced vertically upwards via the pinion 29 and the rack 30 and supports the lid parts 11 by the tensioned tension spring 23 pivot back to the closed position. The opening part closed position is also limited by the abutment of the aforementioned angled portions 25 in the closing joint 15. The current increase detected in this case leads to the disconnection of the electric motor 26.

Alternatively, in addition to the sensor 34, a further sensor, more preferably adjacent to the sensor 34 may be provided, which detects a projecting beyond the area monitored by the sensor 34 area. This second sensor is preferably activated only if the first sensor 34 detects an object or a person in his monitored room. Via the second sensor activated thereafter, a surrounding area of the waste collector 1, that is to say an area which extends beyond the circumference of the waste collector 1, is monitored in order to determine whether a person who may continue to use the waste collector 1 remains in the after-area of the waste collector 1, in order, if appropriate, to use the waste collector 1 one after the other at short intervals. In the closed state of the waste collector 1, however, this second sensor is deactivated, so that people passing by the waste collector 1 can not cause a release.

According to the embodiment in FIG. 12, the electric motor 26 can also act on the slide 16 via a cable pull 35 and on the opening part 10 via this. The cable 35 has this in the usual way via a, the pull cable 36 winding receiving drum 37. The latter is rotated by the electric motor 26 in rotation, the vertical Zugverlagerung of the slider 16 via the pull cable 36, which has the opening displacement of the lid parts 11 result. The return movement of the cover parts 11 in the closing direction is achieved in this embodiment only via the tension spring 23, while the drum 37 is rotated by switching off the electric motor 26 unloaded by running of the traction cable 36. Figure 13 shows an alternative to the first embodiment, wherein the rack 30 is formed from a piston rod 38, which in turn forms the T-bar 18 of the slider 16. The piston rod 38 is part of a pneumatic piston arrangement 39, which is charged in the course of the vertical downward displacement of the piston rod 38 for pivoting the cover parts 11 into the open position. Accordingly, a tension spring 23 can be dispensed with in this embodiment. The restoring force is achieved by the piston assembly 39; this possibly supported by reverse rotation of the pinion 29 via the electric motor 26th

An eccentric drive 40 according to the illustrations in FIGS. 14 and 15 may also be used, in which an eccentric disk 41 is driven via the electric motor 26. This carries an eccentrically articulated arm 42 which engages the T-bar 18 of the slider 16. Due to the eccentric arrangement of the link 42, a rotational movement out of the electric motor 26 is converted into a linear movement of the slide 16.

In this case, the electric motor 26 is preferably a servomotor with a predefined angle of rotation between the two end positions.

Further alternatively, according to the illustrations in FIGS. 16 and 17, an eccentrically articulated crank 43 acts on the slider 16. This also preferably under rotation by means of an electric servomotor.

Also, as shown in Figure 18, the linear vertical displacement of the slider 16 in both the opening direction and in the closing direction of the lid parts 11 via a worm drive 44 done. In this case, a driving pin 45 projecting laterally from the T-bar 18 of the slide 16 engages in an adjacent, vertically oriented worm shaft 46, which extends over the electric motor. motor 26 is rotated in accordance with the respective pivoting direction of the lid parts 11 in rotation.

Finally, FIG. 19 shows an embodiment in which the waste collector 1 has, in the region of the dome 6, a laterally oriented opening part 10 which is integrated into the dome shape and which can be pivoted inwards about the horizontal axis y to the inside of the dome. In this case, the opening part 10 extends into the transition area between the dome 6 and the cylindrical section of the waste collector 1.

The opening part 10 is hinged on the inside of the coupling to an edge 47 delimiting the insertion opening 8 in the upper region, against which a wall section 48 of the opening part 10 which is aligned parallel to the edge 47 in the closure state according to FIG.

The flap-like opening part 10 is spring-biased into the closed position, for which purpose a leg y-engaging leg spring 49 is provided, one leg of which acts on the inside wall side against the opening part 10. The leg spring 49 is tensioned in the course of the opening pivoting movement of the opening part 10.

According to the embodiments described above, the opening part 10 by means of an electric motor 26 is also apparent here, wherein the electric motor 26 is arranged together with the intended accumulator 28 in the dome interior. The electric motor 26 drives an arm 50, at the free end of a pull cable 51 is attached. This is the other end connected to the opening part 10.

In the opening part closure position, the arm 50 abuts against a stop 52 projecting vertically from the dome ceiling. This strut 52 can also be designed in the form of a dome section 12 separating wall, so as to protect the underlying electric motor 26 and the associated mechanism in the open position of the opening portion 10 from contamination.

The opening command causes via the electric motor 26, a pivoting of the arm 50 in the direction of arrow R, which has over the pull cable 51, the Aufschwenkbewegung of the opening part 10 result.

The opening position of the opening part 10 is limited stop. In this case, a wall section of the opening part 10 enters against a corresponding section of the housing-side edge 47 in the vicinity of the axis.

Both stop-limited end positions of the opening part 10 are detected by detecting the associated increase in current of the electric motor 26, which causes the shutdown of the electric motor 26 in the Öffnungssteil- closure position or the pulse control of the electric motor 26 to maintain the open position on the control, not shown. Again, alternatively, in the open position of the electric motor 26 can be short-circuited in a generator mode.

The monitoring of the access to the waste collector 1 is also carried out in this embodiment by means of a sensor 34, which may be placed in the cylindrical portion of the housing 2 near the lower edge of the insertion opening 8 initially to capture from here the area B, the extends upward from the sensor 34. About this sensor 34 corresponding to the immediate access area to the opening part 10 is detected.

As in the embodiments described above, a second sensor 34 'can also be provided in the embodiment according to FIG. rather further positioned, for example, near the upper edge region of the throw-in opening 8 is such that the area B ¹ is monitored in front of the waste collector 1, that is, the area which widens beyond the radius of the waste collector. Preferably, this second sensor 34 'is activated only when the first sensor 34 detects an object or a person in its monitored area.

As an alternative, the sensor 34 'placed in the upper edge region of the throw-in opening 8 can also be the authoritative sensor which indicates the desired use of the waste collector 1 and triggers the opening process.

In FIGS. 20 and 21, a waste collector 1 of similar construction to the embodiment of FIG. 19 is shown. Also, this has in the dome 6 a dome-shaped integrated, laterally oriented opening portion 10 which is pivoted about a horizontal axis y to the dome inside out.

In the diametrically opposite region to the opening part 10, the electric motor 26 acting on the opening part 10 via a pull cable 51 is provided.

The flap-like opening part 10 is spring-biased in the illustrated closed position, for which purpose a leg y grasping leg spring 49 is provided.

The sensor 34 is disposed above the opening portion 10 near the point of coupling, with the sensor 34 received in a separate sensor housing 55.

In the diametrically opposite the opening portion 10 dome region, the separate housing 27 is arranged. This is in the illustrated embodiment example taken integrally in the dome; is adjusted accordingly to the dome curvature. The separate housing 27 protrudes into the dome interior substantially. This by enforcing a correspondingly provided dome opening 56. A housing-side, circumferential collar 57 is supported in the edge region of the dome opening 57 on the outer wall of the dome 6 from. The determination of the separate housing 27 can be done by Klippsung.

Due to the selected arrangement of the separate housing 27 this does not contribute significantly. The thickness in the region of the circumferential collar 57 is selected here in a range of a few millimeters to 12 to 15 millimeters.

The electric motor 26 is fixed on the outside to a housing wall projecting into the dome interior. Alternatively, the electric motor 26 may also be integrated in the housing 27.

Further, in the housing 27, a receptacle 58, not shown for accumulators 28 integrated. This receptacle 58 is apparent from the outside of the dome, to which the outwardly facing housing wall 59 of the separate housing 27 receives a receptacle 58 exposing the opening flap 60.

Further, on the outwardly facing housing 59, an on-off switch 61 is placed, which also disconnects the electronics also housed in the separate housing 27, although not shown, and the electric motor 26 and sensor 34 from the power supply through the accumulators 28. The relevant sensor for triggering the opening movement is designed so that a space is detected, which extends only slightly above the floor plan of the waste collector 1 addition, so that no triggering can be caused by the waste collector 1 passing people. It is much more a targeted approach to the opening portion 10 of the waste collector 1 condition to enter the monitored space.

Further alternatively, the sensor may also be based on generation of an electrostatic field whose disturbance is detected. Accordingly, an opening operation is triggered as soon as a person or an object enters this electrostatic field. It is preferably provided in this regard that the body of the waste collector 1 itself forms a second sensor which builds up an electromagnetic field. This second sensor detects by disturbing the field a person near-posted and, accordingly, the removal of the person from the garbage collector. Only then does the controller generate the command to close the opening portion 10. Thus, the user can terminate the disposal operation independently of a fixed time control.

All disclosed features are essential to the invention. The disclosure content of the associated / attached priority documents (copy of the prior application) is hereby also incorporated in full in the disclosure of the application, also for the purpose of including features of these documents in claims of the present application.
