Description

The invention relates to a power controller in a device handle of a vacuum cleaner, wherein the power controller is designed as a sliding plate and comprises a plurality of power levels.

The invention is concerned with the task of specifying an advantageous power controller in a device handle of a vacuum cleaner.

To improve a power controller of the type in question in particular handling technology, it is proposed that the power controller comprises at least three power levels, with an end power level is adjustable only after overcoming a mechanical obstacle. The power controller can act on both the electrical and mechanical ways on the base unit side motor unit. According to the invention, the first and second power levels can be set without major obstacles at three power levels. A usual detent is also conceivable between these first stages. These two performance levels are usually sufficient for the usual suction work. However, if an increased suction power is required, then the end power level can be reached after overcoming a clear obstacle. This obstacle is more difficult to overcome than the detent positions between the usual power levels, so that the user must overcome this obstacle before the end performance level willful. In this regard, an embodiment is preferred in which the obstacle is an outwardly projecting rib which is to be pushed under a device-side boundary of the power controller free space. This rib, which is also visible on the upper side of the power controller, is to be pressed down in order to obtain the end power level such that a further displacement of the power controller is made possible.

Shown and described is first with reference to Fig. 1 a vacuum cleaner 1 with a, a motor unit, not shown, basic unit G, to which a filter chamber 2 is connected. The basic unit G has a cantilever over the filter chamber 2 boom 3, at the free end of a plug-in receptacle 4 is formed. In this plug-in receptacle 4, a device stem St is inserted, wherein the insertion portion of the device stem St is formed as an aluminum profile section 5. By contrast, the adjoining handling section 6 is preferably produced by the plastic injection method.

The device handle St is telescopically displaceable in the usual way in the arm 3 of the basic unit G, wherein the desired extension position of the device handle St is latched. For this purpose, the device stem St evenly distributed in the longitudinal extension of the same arranged recessed recesses 7 Entry of a provided in the region of the plug-in receptacle 4 of the boom 3 locking pin 8 (see Fig. 19 ). This spring-loaded in the latching direction latching pin 8 is zurückverlagerbar by means of a rocker-like handle 9 to release the device handle St.

The electrical connection is made via a connection cable 10, which at one end has a standard electrical connector and at the other end a device connector receptacle 11. As in particular from the representations in the Fig. 3 and 4 To recognize, the device connector receptacle 11 a running in the direction of insertion r slot 12, which separates an electrical area 13 of a handle 14. The electrical region 13 in this case has a substantially rectangular cross-section. The arranged in this electrical area 13 tab receptacles 15 which are electrically connected and rearwardly connected to the connecting cable 10, open into a recessed to the free end face 16 of the electric area 13 receiving floor 17th

Furthermore, the electrical area 13 extends essentially in the axial extension of the connection cable 10.

The handle 14 of the device connector receptacle 11 extends substantially parallel to the electrical area 13, the slot 12 provided between the electric area 13 and the handle 14 opening in the plug-in direction r. Furthermore, the handle 14 is provided on the upper side with a profiling 18 for improved handling. On the underside, the handle 14 has a concave shape 19.

As in particular from the representations in the Fig. 6 and 7 to recognize the handle 14 projects beyond the electric range 13 in the direction of insertion r.

In addition, the slot 12 facing inner edge of the handle 14 is provided with a rib 20 extending in the direction of insertion r.

The device connector receptacle 11 of the connection cable 10 is coupled for electrical contacting of the blower motor arranged in the basic unit G with a plug 22 in the receptacle 4 of the base device-side arm 3, flat plug 21 having device plug 22 coupled, said device plug 22 in the device Plug receptacle 11 is immersed and the tab 21 engage in the correspondingly aligned tab receptacles 15 electrically conductive.

The device-side device connector 22 is based on a plan view of the receptacle 4 as shown in FIG Fig. 5 assigned to a lateral area. The formed between the electric area 13 and the handle 14 of the device connector receptacle 11 slot 12 takes in the coupled position to the device connector 22 adjacent wall portion of the boom 3, wherein by intervention of said handling-side rib 20 in a correspondingly shaped and positioned Wandungsnut 23 of the boom 3 is given a further guide the device connector receptacle 11 in the direction of insertion r.

As from the representations in the Fig. 6 and 7 to recognize the pluggability of the device connector receptacle 11 is independent of whether a device handle St is inserted for use of the vacuum cleaner 1 as a stick vacuum cleaner or whether it is removed to use the vacuum cleaner 1 as an over-floor device.

If the device handle St is plugged into the plug-in receptacle 4, then the appliance plug receptacle 11, in particular the electrical area 13, and the itself adjoining connecting cable 10 in an opening to a narrow side of the device stem cross-section outward insertion slot 24 a, the diameter and opening width is adapted to the electrical range dimensions of the device connector receptacle 11. This insertion groove 24 extends over the entire length of the device stem St , wherein the groove cross-section is reduced in the region of the handling section 6. As a result, a relative displacement of plugged-device connector receptacle 11 and device stem St, in particular the aluminum profile section 5 is given in a telescopic longitudinal displacement of the device handle St.

The insertion groove 24 is partially closed in the region of the handling portion 6 by tongue-like protruding from the opposite longitudinal edges of the insertion groove 24 mounting baffles 25, wherein first two sides of the Einlegeutabschnittes in the handling section 6 two mounting baffles 25 are oppositely projecting in the longitudinal direction of the insertion groove 24 side by side. Between these pairs of mounting baffles 25 there remains one each on the diameter of the connecting cable 10 oriented, slit-shaped opening 26th

Due to the arrangement of these mounting baffles 25, the connecting cable 10 is caught in the insertion groove 24. However, removal of the connection cable 10 is made possible in a deliberate manner, overcoming the mounting baffles 25. Retrofitting of the connection cable 10 can be facilitated by an elastic configuration of the mounting baffles 25.

As shown in the drawings, 25 may be provided between the two end-side pairs of mounting baffles a further, central Halteschikane.

A lower broad side of the handling section 6 associated with Aufwickel Halterungsausformungen 27 are provided, around which the connection cable 10 can be wound to save space when not using the vacuum cleaner 1.

On the side facing away from the Halterungsausformungen 27 broad side of the handling section 6 is a separate, but with the handling section 6 materially connected, bow-shaped handle portion 28 is formed.

The device-distal end of the insertion groove 24 merges into a cable-protecting, soft radially outwardly curved and partially in the handle portion 28 expiring outlet opening 29, whereby a device-side kink protection for the connecting cable 10 is provided.

The power control of the arranged in the base unit G motor unit is carried out when using the vacuum cleaner 1 as an over-floor device, d. H. In the illustrated embodiment, four power levels are adjustable, with an off-level with A, the two following power levels with L1 and L2 and a End power level is denoted by L3.

With this power controller 30 is a to the receptacle 4 extending through the boom 3 Fernwirkungsfortsatz 31 whose longitudinal axis extends in extension of the axis of rotation y of the power controller 30 and thus parallel to the Gerätestielachse x. This Fernwirkungsfortsatz 31 is longitudinally movably received rigidly on the power controller 30. However, that is given a relative angular mobility to each other. This is achieved in that the Fernwirkungsfortsatz 31 consists of a plastic construction, wherein two between a groove 32 leaving longitudinal ridges 33 engage in a corresponding slot opening of the power controller 30 and thus allow an elastic deformation.

The Fernwirkungsfortsatz 31 serves the mechanical long-range effect of the motor unit by arranged in the handle portion 28 of the device Stem St further power controller 34 when using the vacuum cleaner 1 as a handle vacuum cleaner with a device stem St. This power controller 34 is designed as a sliding plate, by means of which the same power levels as with the device-side power controller 30 can be selected.

The sliding power controller 34 acts on a telecontrol rod 35 accommodated in the equipment handle St. The latter is designed as a turning bar and held in a, the insertion slot 24 adjacent pipe section 36 of the device handle St. The arrangement is chosen so that the remote action rod 35 in the pipe section 36 is freely rotatable, but not displaced in the longitudinal direction.

The coupling between power controller 34 and remote action rod 35 via a worm gear 37, whereby the linear movement of the power controller 34 is converted into a rotational movement of the remote action rod 35. As in particular from the illustration in Fig. 12 as well as from the schematic representation in Fig. 21 For this purpose, the power controller 34 has a shoe 39, which can be displaced in a guide window 38, which has a groove 40 in its end region facing away from the power controller 34. In this engages an end arranged on the remote action rod 35 screw rib 41 with its T-shaped Profile on (see sectional illustration in Fig. 12 ). About this interaction of worm rib 41 and groove 40, the linear movement of the power controller 34 and the shoe 39 is converted into a rotational movement of the remote action rod 35.

The worm gear 37 remote from the end of the remote action rod 35 terminates at a distance from the associated free end of the device stem St, the latter having in this end portion a radially outwardly widening plug opening 42.

The remote action rod 35 is further formed like a tube and has internally a radially inwardly extending rib 43. The length of this axially parallel extending rib 43 is adapted to the possible Teleskopierweg the device handle St.

In the course of insertion of the device stem St in the receptacle 4 of the basic unit G first causes the Einweiserfläche formed by the widening insertion opening 42 insertion of the free end of the base device remote action extension 31 through the insertion opening 42 and hereafter into the tubular remote control rod 35. Finally, a Rotary coupling between remote action extension 31 and remote action rod 35 achieved by the rod-side rib 43 engages in a radial groove 44 on the extension side (see FIG. Fig. 19 ). Thereafter, the converted by means of the worm gear 37 sliding movement of the handle side power actuator 34 is transmitted via the remote action extension to the device-side power controller 30 and via this optionally with the interposition of electronics to the motor unit. Here, the already described torsionally flexible coupling between Fernwirkungsfortsatz 31 and Power controller 30 of advantage, as this tolerances can be included non-destructive.

So that the remote action rod 35 and the remote action extension 31 can also be found independently of the respective position of the power controllers 30 and 34, a guide ramp 45 is formed on the remote action extension 31 in front of the groove 44. The latter is designed as a central, perpendicular to the axis of rotation rib 46 with two-sided guide surfaces 47, wherein the guide surfaces 47 to screw over the length of the wall into the groove 44. According to this embodiment causes at an unequal switch position of the two power controller 30 and 34, the impact of the guide rod-side rib 43 on one of the two guide surfaces 47 and thereafter further continued displacement of the device stem St in the insertion direction r Drehvor- or Drehrückverlagerung of the remote action extension 31 in the corresponding position of groove 44 and rib 43. Accordingly, the device-side power controller 30 always takes the position of the power controller 34 when inserting the device handle St.

As already mentioned, the vacuum cleaner 1 shown and described has three active power stages L1 to L3. According to the invention, it is provided that the end power stage L3 can be adjusted only after overcoming a mechanical obstacle, in particular at a setting via the power handle 34 on the device handle. For this purpose, this has a rib 49 projecting upwards in the direction of the actuating projection 48 of the power actuator 34 on reaching the power level L2 occurs against a boundary edge 50 of the power actuator Betätigungserviraumes 51. In response to a deliberate pressure actuation of the power controller 34, this obstacle is underrun by the rib 49, after which the desired End power level L3 is reached (cf. Fig. 22 ). The chosen obstacle can only be overcome by willpower.
