Description

VACUUM CLEANER

The invention relates to a vacuum cleaner comprising a dirt collecting container, a suction unit and at least one filter element for filtering the sucked from the suction unit from the dirt collecting air, a filter cover which covers the at least one filter element cleanroom side in a covering position and the cleanroom-side removal of the at least one filter element in a removal position is pivotable, at least one arranged on the at least one filter element side facing the filter cover battery receptacle in which at least one battery for providing electrical energy for the suction unit is arranged, wherein the at least one battery receptacle and the at least one battery are arranged in a battery compartment and comprising a battery compartment cover which closes the battery compartment in a closed position and which is pivotable to open the battery compartment in an open position.

Such a vacuum cleaner is described in WO 2012/062579 Al the same applicant. In the vacuum cleaner two battery holders for receiving two rechargeable batteries are arranged on top of the filter cover. During battery operation of the vacuum cleaner, the filter cover occupies the covering position and the battery compartment cover assumes the closed position. To remove the batteries from the battery holders, the battery cover can be transferred from the closed position to the open position. If the filter element is to be removed from the vacuum cleaner, for example for replacement or for cleaning, the filter cover can additionally be transferred from the covering position into the removal position and the cleanroom side can be accessed on the filter element. - -

The vacuum cleaner described in WO 2012/062579 AI proven in practice. Nevertheless, it would be desirable to design the vacuum cleaner even more reliable.

Object of the present invention is to provide a vacuum cleaner of the type mentioned with improved protection of at least one battery receptacle and / or the at least one battery from external influences.

This object is achieved in a generic vacuum cleaner according to the invention in that the vacuum cleaner comprises a locking device for locking the filter cover in the removal position and that the battery compartment cover in the open position under the influence of gravity on top of the removal position engaging filter cover is supported and the at least one battery receptacle and / or covering at least one battery.

In the vacuum cleaner according to the invention, the battery compartment can be opened by transferring the battery compartment cover in the open position, for example, to exchange the at least one battery. To access the at least one filter element, the filter cover can additionally be transferred to the removal position. It is possible to protect the at least one battery and / or the at least one battery receptacle against external influences when the filter cover occupies the removal position and the battery cover covers the open position. In the removal position, the filter cover is locked by means of the locking device, so that the user can reach the cleanroom side of the filter for maintenance in a user-friendly manner. The battery compartment cover still takes the open position, wherein it is supported on the top of the filter cover under the influence of gravity. The support can be carried out directly on the filter cover or indirectly, for example on the top of the at least one battery receptacle or on top of a recorded in the at least one battery receptacle battery. The - - Supporting battery cover covers the at least one battery holder and / or the at least one battery. This makes it possible to protect the at least one battery and / or the at least one battery receptacle not only from external influences, in particular dirt and / or liquid such as splashing, when the battery compartment cover is closed, but also in the opening position einnehmender battery cover, in particular after the filter cover has been transferred to the removal position. This also facilitates a user's handling of the vacuum cleaner, which allows a user to focus on the maintenance of the filter, without paying special attention to the protection of the at least one battery receptacle and / or the at least one battery, for example, from dirt and spray.

Preferably, the battery cover covers the filter cover in the closed position and / or in the open position, so that the filter cover is protected from external influences such as dirt and / or spray water.

It is advantageous if the vacuum cleaner free of a further locking device for locking the battery cover in one of the

Closed position is different position. This gives the possibility to lock the battery cover alone in the closed position. If the battery compartment cover is opened and transferred from the closed position to another position, no further locking is provided than via the support in the open position on the filter cover. This can ensure that the at least one battery and / or the at least one battery receptacle are covered by the battery compartment cover engaging the open position when the filter cover occupies the removal position.

Preferably, the filter cover can only be transferred from the covering position into the removal position after the removal of the at least one battery from the at least one battery receptacle. The at least one battery, - - For example, if it is sensitive to external influences such as dirt and / or spray, is removed for improved protection from the at least one battery receptacle before the filter cover is transferred to the removal position. Instead, as long as the filter cover occupies the removal position, the at least one battery can be stored protected at a location which is even better suited for this purpose.

As mentioned above, the battery cover and the filter cover are pivotable. For example, the battery cover and the filter cover are pivotable about horizontally oriented pivot axes. For example, the battery cover and the filter cover may be pivoted upward from a back side of the vacuum cleaner toward a front side of the vacuum cleaner.

Position and direction indications such as "top", "bottom", "horizontal" or the like are to be understood in this case based on an operating position of the vacuum cleaner on a footprint, the horizontal orientation is assumed. "Front" and "rear" refer in the present case to a longitudinal or main direction of movement of the vacuum cleaner.

The angle at which the battery compartment cover and / or the filter cover are respectively pivoted for transferring from the closed position to the open position or from the covering position into the removal position is advantageously less than 90 °. As a result, the battery compartment cover can cover the at least one battery receptacle and / or the at least one battery in a simpler manner.

In an implementation of the vacuum cleaner in practice, it proves to be advantageous if the pivot angle for transferring the filter cover from the covering position into the removal position is greater than the pivot angle for transferring the battery compartment cover from the closed position to the open position. This gives for example the possibility of the filter cover in the removal position at a closer distance to the open position a - Take - taking battery cover as in the covering position relative to the closed position engaging battery compartment cover. Thereby, in particular, there is the possibility that the battery compartment cover in the open position can cover the at least one battery and / or the at least one battery receptacle and in particular the filter cover to a greater extent than in the closed position. This can ensure reliable protection.

For example, the pivoting angle for transferring the filter cover from the covering position into the removal position is approximately 50 ° to approximately 75 °, for example approximately 65 °. The swing angle for transferring the battery cover from the closed position to the open position may be, for example, about 40 ° to about 60 ° and, for example, about 50 °.

The locking device is conveniently held on a housing enclosed by the vacuum cleaner. For this purpose, the vacuum cleaner may have a housing wall, on which the locking device is held. The housing wall is, for example, a wall which separates a receiving space for the suction unit from the battery compartment.

It is advantageous if the locking device comprises at least one locking element, which can be transferred from a release position into a locking position, wherein the at least one locking element cooperates in the locking position with the filter cover to the locking and not cooperating in the release position with the filter cover. For example, the at least one locking element is in the locking position in engagement with the filter cover, whereas it is in the release position out of engagement with the filter cover.

In a structurally simple embodiment of the locking device, it is advantageous if the locking element locked in the locked position with the filter cover. - -

For transferring from the release position into the locking position and vice versa, the locking element is preferably movably mounted on a stationary housing portion of the vacuum cleaner. In particular, the locking element may be pivotally mounted on a fixed housing portion of the vacuum cleaner. The pivot axis is preferably parallel to the

Pivot axis or the pivot axes, around which the battery compartment cover and the filter cover are pivotable.

A movable mounting of the locking element on a fixed housing portion allows reliable locking of the filter cover in the removal position. The force required for this purpose can be derived directly to the housing. A lock on a movable housing portion, as is the case for example in the vacuum cleaner described in WO 2012/062579, is not required on the other hand. In particular, no locking on the battery compartment cover needs to be done.

Advantageously, the locking element is movably mounted above the filter cover in the battery compartment, so that it is accessible in a simpler manner, for example for maintenance or repair.

It is advantageous if the locking element comprises a pivot lever or is designed as such, which is movably mounted with a first portion on a fixed housing portion of the vacuum cleaner and having a second portion on which the removal position engaging filter cover in the locking position of the pivot lever supported. This allows a structurally simple embodiment of the locking device can be achieved. About the pivot lever, a supporting force can be derived on the fixed housing section.

Advantageously, the locking device comprises at least one elastic element, under the bias of which the locking element can be transferred from the release position into the locking position. This allows to a certain extent - - "automatic" locking of the filter cover when it is transferred to the removal position. The at least one locking element is biased by means of the at least one elastic element with respect to the locking position and can take this with taking the removal position through the filter cover. There is no need for an action by the user.

Conveniently, the at least one elastic element comprises a leg spring or is designed as such, which is supported on a fixed housing portion of the vacuum cleaner and the at least one locking element. This allows a structurally simple design can be achieved.

It proves to be advantageous if the locking device of an engagement opening for removing the at least one filter element is arranged opposite to the filter cover, which engagement opening is released when taking the removal position through the filter cover. The locking device is thereby arranged on a side facing away from the engagement opening of the filter cover. This facilitates a user's access to the at least one filter element without the locking device blocking the user from doing so.

Conveniently, the vacuum cleaner comprises a second locking device for locking the filter cover in the covering position, wherein the second locking device is designed so that it can be actuated only with the use of tools. This allows a reliable locking of the filter cover in the covering position. "Only with the use of tools" in the present case is to be understood in particular as meaning that a manual actuation of the second locking device by a user is not possible, so that the filter cover can be transferred to the removal point.

Preferably, the second locking device is arranged at least by the at least one battery arranged in the at least one battery receptacle - - partially covered. This ensures, for example, that the at least one battery is removed from the at least one battery receptacle before the second locking device is actuated using tools. When pivoting the filter cover from the covering to the removal position, the battery, as mentioned above, be stored in a separate location.

To achieve a structurally simple embodiment of the second locking device, it is advantageous if the second locking device comprises at least one engaging element coupled to the filter cover, which is in an open position out of engagement with a stationary housing portion of the vacuum cleaner and in a closed position with the housing portion is engaged. The engagement may be non-positive and / or positive.

It can be provided, in particular, that the second locking device has at least one rotary closure comprising or forming the at least one engagement element and held on the filter cover. By rotating the rotary closure, an engaging element encompassed or formed therefrom can be rotated relative to the fixed housing section and brought into frictional and / or positive engagement therewith, or such engagement can be canceled.

It is advantageous if the vacuum cleaner comprises a filter cleaning device for cleaning the at least one filter element. This makes it possible to detach particles adhering to the at least one filter element and thereby extend the maintenance interval for the filter element. The suction power of the vacuum cleaner can be kept almost constant using the filter cleaning device without changing the filter in order to achieve a better overall cleaning result.

Conveniently, the filter cleaning device is held on the filter cover. As a result, for example, there is the possibility of the filter cleaning device during pivoting of the filter cover in the sampling - -

Lift position so that it is easier to access the maintenance.

In the covering position of the filter cover, the filter cover in the covering position or a filter cleaning device held on the filter cover preferably closes off a suction space via which the at least one filter element is subjected to negative pressure on the cleanroom side by the suction unit. A separate sealing of the suction can be saved.

It can be provided that the vacuum cleaner has a cooling device for cooling the at least one battery in the at least one battery receptacle. For example, a fan is integrated in the filter cover, with the air in the battery compartment cover is circulated. It can also be provided that passages for ventilation air are arranged on the filter cover and on the at least one battery, so that cooling air of the at least one battery can be selectively supplied for cooling by using the fan.

The vacuum cleaner may be a so-called wet-dry vacuum cleaner, which is in particular a bagless vacuum cleaner. The vacuum cleaner may have a lower part, which encloses or forms a dirt collecting container. Further, the vacuum cleaner may have an upper part, in which the suction unit is arranged and which is released for emptying the dirt collecting container from the lower part. The upper part may comprise the at least one filter element, the filter cover and the battery compartment.

Preferably, the jam cleaner is a hybrid vacuum cleaner having a connectable to a power grid connection cable for providing electrical energy. This allows a more versatile use of the vacuum cleaner, which can be operated both in network operation as well as in battery operation. It can be provided that the at least one battery in the at least - - it is possible to recharge a battery when the connection cable is connected to the power supply network.

Figure 1 shows a perspective view of a generally occupied by the reference numeral 10 advantageous embodiment of a vacuum cleaner according to the invention. The vacuum cleaner 10 is designed as a so-called wet-dry vacuum cleaner with which both solids and liquids can be sucked. - -

The vacuum cleaner 10 comprises a lower part 12 and an upper part 14, which is detachably mounted on the lower part 12 and connected in this state with the lower part 12. On the lower part 12, a chassis 16 is arranged at the bottom, so that the vacuum cleaner 10 can be moved over a bottom surface 18.

Position and directional indications such as "top," "bottom," "horizontal," or the like herein refer to positioning the vacuum cleaner on the floor surface 18 in an operative position, with the floor surface 18 being considered horizontally oriented. "Front" and "rear" refer to a longitudinal or main direction of movement of the vacuum cleaner 10.

The chassis 16 has on a rear side 20 of the vacuum cleaner 10 two wheels (only one impeller 22 shown). At a front side 24 of the vacuum cleaner 10, the chassis 16 has two swivel castors 26 and 28.

The lower part 12 forms a dirt collecting container 30, into which dirt can be sucked in and deposited therein by means of a suction inlet 32 arranged on the front side 24. At the suction inlet 32 a not shown in the drawing, known per se suction hose can be connected.

The upper part 14 receives electrical devices of the vacuum cleaner 10. Schematically represented by this are a suction unit 34, via which the dirt collecting container 30 can be subjected to negative pressure, and an electronic control unit 36, also shown schematically. The control unit 36 converts, for example, operating instructions of a user to control elements, not shown in the drawing, of the vacuum cleaner 10.

The suction unit 34 is arranged in a receiving space 38 formed in the upper part 14. The receiving space 38 is formed in the front half of the upper part 14, and it communicates with a suction space 40 in the rear half of the - -

Upper part 14 in flow communication (Figure 3). The receiving space 38 and the suction space 40 are separated from each other by an intermediate wall 42 which extends from an upper surface 44 of the vacuum cleaner 10 downwards and is arranged approximately centrally in the longitudinal direction thereof. In the intermediate wall 42 through openings 46 are provided for sucked by the suction unit 34 suction air. The intermediate wall 42 is a portion of a housing 70 of the vacuum cleaner and formed in stages.

In the transverse direction of the vacuum cleaner 10, the intermediate wall 42 extends from its left side to its right side. The lower side, the intermediate wall 42 is connected to an intermediate wall, not shown in the drawing, which is arranged on the underside of the upper part 14 and the

Dirt collecting container 30 is covered on top, when the upper part 14 is placed on the lower part 12.

In this further intermediate wall, a passage opening is formed, via which the suction space 40 is fluidically connected to the dirt collecting container 30, wherein a filter element 48 is inserted into the passage opening. From the suction unit 34 from the dirt collecting container 30 sucked air can be filtered by the filter element 48. The filter element 48 is, for example, a flat pleated filter, in particular of a paper or polyester material.

With increasing operation of the vacuum cleaner 10, particles settle on the filter element 48, so that the pressure in the dirt collecting container 30 increases and suction material can only be sucked into it with reduced power. For cleaning the filter element 48 and the achievable thereby maintaining the lowest possible pressure in the dirt collecting container 30, the vacuum cleaner 10 has a filter cleaning device 50. The filter cleaning device 50 is arranged above the filter element 48 and held at the bottom on a filter cover 52. The filter cover 52 may occupy a covering position shown in Figure 2, in which it covers the filter element 48 above. In this case, a lower edge 54 of the filter cleaning - - supply device 50 sealingly against an outer edge 56 of the filter element 48 at. This makes it possible to save a separate seal of the suction space 40 upwards.

The filter cleaning device 50 can be controlled electronically by the control unit 36. This is, as well as the structure of the filter cleaning device 50, known per se and is therefore not discussed here. For example, the filter cleaning device 50 comprises a closing valve, which can be opened by the control unit 36 at regular intervals, so that the filter element 48 cleanroom side, ie. from the dirt collecting container 30 side facing away, is subjected to pressure surges. The pressure surges are formed as a result of inflowing external air, which can flow into the upper part 14 through a foreign air opening, not shown in the drawing, so that the filter element 48 is acted upon open room with external air at atmospheric pressure with the closing valve open.

The filter cover comprises a basic shape of a plate-shaped first portion 58 and fixed thereto second portion 60, which forms a support arm for pivotally mounting the filter cover 52 to the intermediate wall 42. The second section 60 extends arcuately forwardly and upwardly from the first section 58 and is located centrally of the first section 58 in the transverse direction of the vacuum cleaner 10. The end of the second section 60 opposite the first section 58 is pivotably mounted on a hinge 62 shown only schematically in FIG. 4 about a pivot axis 64 defined by the latter. The pivot axis 64 extends in the transverse direction of the vacuum cleaner 10 and is aligned horizontally.

Starting from the covering position in which the filter cover 52 covers the filter element 48, it can be transferred to a removal position shown in FIGS. 3 and 4, in which the filter element 48 can be removed from the rear side 20 of the vacuum cleaner 10. On the pivoting of the filter cover 52 and its removal position will be discussed below. - -

The filter cover 52 can be locked in the covering position by means of a locking device 66 on a stationary housing section 68 of the housing 70 of the vacuum cleaner 10. In the housing portion 68 is a rear wall of the housing 70 laterally adjacent to the filter element 48, which is shown in sections in Figure 5 schematically. The housing section 68 comprises at the bottom a recess, which is bounded on the top by a shoulder 72.

The locking device 66 has two closure elements 74 and 76, which are arranged rearwardly on the first portion 58 laterally adjacent to the housing portion 68 when the filter cover 52 occupies the covering position. The closure elements 74 and 76 are configured as rotary closures 78 and 80, which are each mounted for rotation about vertical or substantially vertical axes on the first section 58. At their lower ends, the closure elements 74 and 76 have engagement elements 82 and 84 (FIGS. 3 and 5).

By rotating the rotary fasteners 78 and 80 about their respective axes, the engagement members 82 and 84 can be brought into a closed position with substantially positive engagement with the shoulders 72 of the housing portion 68, or the engagement can be canceled. In existing engagement, the filter cover 52 is locked to the housing portion 68. When the engagement is canceled, the engagement members 82 and 84 assume an open position, and the filter cover 52 is unlocked in the cover position and can be pivoted about the pivot axis 64.

The rotary fasteners 78 and 80, and thus the locking device 66 are presently designed so that a manual actuation of the locking device 66 by a user is not possible. Instead, the use of a tool is required, such as a screwdriver - - hers, which can be brought into engagement with the rotary fasteners 78 and 80, so that they can be rotated about the respective axes.

The actuatable only with the use of tool locking device 66 allows reliable and secure locking of the filter cover 52 in the covering position.

On the upper side of the filter cover 52 and from this are, in the transverse direction of the vacuum cleaner 10 each side of the second portion 60, two battery receptacles 86 and 88 are arranged. In each of the battery receptacles 86 and 88, a rechargeable battery 90 and 92 is held. The batteries 90 and 92 are designed for example as lithium-ion batteries and are used to operate the vacuum cleaner 10 without connection to an external power supply device. However, the vacuum cleaner 10 is a hybrid vacuum cleaner which additionally has a connection cable 94 shown in sections. At a free end of the connection cable 94 (not shown), a power plug is arranged so that the vacuum cleaner 10 can also be connected to a power supply network and in particular connected to a power outlet.

The batteries 90 and 92 are arranged in a battery compartment 96 of the upper part 14, which can be closed by a battery cover 98. The battery compartment cover 98 is a part of the housing 70, namely a housing cover 100, which is mounted on the upper side 44 by means of a hinge 102 pivotally mounted on the housing 70 otherwise. The hinge 102 defines a pivot axis 104 which is aligned parallel to the pivot axis 64 and accordingly extends transversely of the vacuum cleaner 10 and horizontally.

The housing cover 100 may assume a closed position shown in Figure 1, in which it closes the battery compartment 96. In this case, the housing cover 100 covers the batteries 90 and 92, the battery holders 86 and 88 and the filter cover 52. With a locking device 105, the - -

Housing cover 100 are locked to the housing 70. The locking device is for example a latching device.

If the housing cover 100 assumes the closed position, the filter cover 52 assumes the covering position, so that the filter element 48 is covered on the top side and the battery compartment 96 is closed. In the closed position, the housing cover 100 protects the batteries 90 and 92, the battery holders 86 and 88 and the filter cover 52 against external influences, such as dirt and / or splashing.

To remove the batteries 90 and 92 from the battery holders 86 and 88, the locking of the housing cover 100 can be released and the housing cover 100 can be transferred about the pivot axis 104 into an open position (FIG. 2). In this case, the housing cover 100 is pivoted upward from the rear side 20 in the direction of the front side 24 and the battery compartment 96 is opened.

If the filter element 48 or the filter cleaning device 50 is to be maintained when the housing cover 100 is open, the filter cover 52 can subsequently be transferred from the covering position into a removal position (FIGS. 3 and 4). For this purpose, it is first necessary, as mentioned above, to operate the locking device 66, using tool. In addition, it is necessary to remove the batteries 90 and 92 from the battery holders 86 and 88 because the filter cover 52 including the batteries 90 and 92 can not be pivoted. This is because the batteries 90 and 92 come into contact with the intermediate wall 42 and block pivoting of the filter cover 52.

It may be envisaged that a user may not operate the rotary fasteners 78 and 80 until the batteries 90 and 92 have previously been removed from the battery seats 86 and 88. - -

After removing the batteries 90 and 92 and actuating the locking device 66, the filter cover 52 can be pivoted from the rear side 20 upwards in the direction of the front side 24 and transferred to the removal position (FIGS. 3 and 4). To lock the filter cover 52 in the removal position, the vacuum cleaner 10 comprises a further locking device 106.

The locking device 106 includes a locking element 108 in the form of a pivot lever 110. The pivot lever 110 has a first portion 112 which is pivotally mounted on the intermediate wall 42 about a pivot axis 114 defined by it. The pivot axis 114 is aligned parallel to the pivot axes 64 and 104 and thus extends horizontally and transversely of the vacuum cleaner 10. The first portion 112 is disposed above the first portion 58 of the filter cover 52 on the intermediate wall 42 (Figure 2).

A second section 116 of the pivoting lever 110 is aligned at right angles to the first section 112 and extends in a direction away from the intermediate wall 42 direction. In the transverse direction of the vacuum cleaner 10, the second portion 116 is disposed between a housing portion 118 of the housing 70 on the left side of the vacuum cleaner 10 and a side edge 120 on the left side of the first portion 58.

At a free end, the pivot lever 110 has a projecting in the direction of the side edge 120 projection 122. The projection 122 is assigned a recess 124 on the side edge 120 at its side facing the intermediate wall 42 side. The recess 124 is slit-shaped and has, based on an arrangement of the filter cover 52 in the covering position, from the front to the rear facing course.

The locking device 106 comprises an elastic element 126 which is configured as a leg spring 128 which is penetrated by the first section 112. The leg spring 128 is supported on the intermediate wall 42 and - - On the other hand on the second section 116 from. The pivot lever 110 is thereby biased with an upwardly pioneering biasing force for pivoting about the pivot axis 114.

In the covering position of the filter cover 52, this is not shown, the projection 122 is in a release position of the pivot lever 110 on the bottom side of the side edge 120, but without engaging in the recess 124. When the filter cover 52 is transferred to the removal position, the pivot lever 110 is raised under the action of the biasing force of the leg spring 128, the projection 122 sliding along the side edge 120.

If the filter cover 52 is raised so far that the projection 122 can engage in the recess 124, the pivot lever 110 locks in a locked position with the filter cover 52 (Figures 3 and 4). As a result, the filter cover 52 is locked in the removal position, and the filter element 48 can be removed user-friendly cleanroom side of the vacuum cleaner. Alternatively or additionally, the filter cleaning device 50 can be maintained.

In the removal position of the filter cover 52, the housing cover 100 continues to occupy the open position. However, the vacuum cleaner 10, apart from the locking device 105 for locking the housing cover 100 in the closed position, free from a further locking or locking device for the housing cover 100 in a different position, and thus in particular the open position.

In the open position, the housing cover 100 instead lies alone on the top of the filter cover 52 under the influence of gravity and rests on this. As a result, it is possible to cover the battery compartment receptacles 86 and 88 and the filter cover 52 at the top. This offers the advantage that even when the housing cover 100 occupies the open position and the filter cover 52 assumes the removal position, the battery - - Rieaufnahmen 86 and 88 and the filter cover 52 are protected on the top side from external influences, in particular dirt and / or spray.

The batteries 90 and 92, which have already been removed before pivoting the filter cover 52 into the removal position, can also be stored in a separate location protected from dirt and / or sprayed water.

To be particularly user-friendly, it turns out that the filter cover 52 is locked when transferred to the removal position to a certain extent "automatically". This is done under the bias of the pivot lever 110 due to the leg spring 128 with respect to the Arretierrstellung.

To close the filter cover 52 this is raised slightly, so that the projection 122 of the recess 124 is unlocked. The user then acts on the pivot lever 110 with a directed against the biasing force of the leg spring 128 force and at the same time lowers the filter cover 52 again. As a result, the projection 122 again come to rest at the lower edge of the side edge 120 behind the recess 124 and be transferred to the release position. The filter cover 52 can then be transferred to the covering position and locked by means of the locking device 66.

Subsequently, the batteries 90 and 92 can again be inserted into the battery holders 86 and 88 and the housing cover 100 can be transferred to the closed position, in which the battery compartment 90 is closed again.

As advantageous in the vacuum cleaner 10 also proves that the pivot angle by which the filter cover 52 is transferred from the covering position into the removal position is greater than the pivot angle for pivoting the housing cover 100 from the closed position to the open position. In the present case, the filter cover (see Figure 4) is pivoted by about 65 °, whereas the housing cover 100 is pivoted by about 50 °. This offers the possibility of the battery receptacles 86 and 88 and the - -

Cover filter cover 52 to the housing cover 100 to an even greater extent, as is the case when the filter cover 52, the cover position and the housing cover 100 assumes the closed position.
