Definitions
- the invention first relates to a method for operating a vacuum cleaner with a suction nozzle, wherein a suction air volume flow is generated by motor in the vacuum cleaner, by means of which a negative pressure is created in the suction nozzle, and one that occurs during the method (overrun and / or pull operation) of the vacuum cleaner Force loading, which ultimately affects the user as thrust or tensile resistance, is measured.
- a method of the type in question is known from W097 / 26819 A2.
- a method is specified by means of which the respective instantaneous direction of movement, ie the direction of displacement of the suction nozzle, is detected and the vacuum which acts upon it is varied as a function thereof.
- This solution results from the knowledge that, in particular when vacuuming carpets, there is a relatively high negative pressure in the area of the suction mouth corresponding to the floor to be maintained, which negative pressure in itself ultimately has a resistance for the user. Due to the actuation of the suction nozzle by the user, usually with the aid of a rigid handle, e.g. w. Another resistance occurs in the suction pipe or the like, which varies depending on the direction of travel of the suction nozzle.
- the force load is measured in overrun mode and the thrust resistance is leveled. It is further preferred that the force load is measured in both the pushing and pulling operations and, as a result, both the pushing and pulling resistance is regulated to approximately the same level.
- the action takes place through a change in the negative pressure in the suction nozzle, with a measure being selected with regard to the change in negative pressure which achieves an appropriate, constant force load for the user with an optimal cleaning result, in particular based on the surface. This proves to be particularly advantageous in that, depending on the type of carpet, only certain maximum volume flows are required for carpet cleaning in order to optimally clean the carpet. Higher volumetric flows would only be higher, wanted to generate pushing or pulling forces.
- a constant adjustment of cleaning performance and force load can be achieved, whereby in addition to the nature of the floor to be cleaned, further parameters for variation can also be consulted, such as the type and operating state of the suction nozzle and / or the pressure load by the user, for example, via the suction pipe onto the suction nozzle.
- the force load which affects the user as thrust or pull resistance, can be measured in the area of an actuating rod, for example in the area of a suction pipe or a handle of the vacuum cleaner.
- a force sensor sits in the power flow chain e.g. between the handle of the vacuum cleaner for handheld vacuum cleaners or the suction pipe for cylinder vacuum cleaners and the suction nozzle.
- This force sensor registers the pushing force in both pulling and pushing operations.
- the measured variable serves as an input signal to a control system which, for example, influences the vacuum at the suction nozzle in such a way that the pushing force corresponds to a predetermined target.
- the force load in the suction nozzle can be measured.
- suction nozzles which have a rotatable brush for soil cultivation which can be driven by an electric motor, it is proposed that the current consumption of the brush motor be evaluated in addition to the force load.
- the change in vacuum is carried out disproportionately or disproportionately to the measured pressure force and / or output of the brush motor.
- the shear and / or tensile resistance can also be regulated to an appropriate level for the user by activating the traversing drive, even on floors which, due to their design or because of the degree of contamination, have to be cleaned with an increased cleaning performance and thus with an increased vacuum ,
- the traversing drive can only be activated in overrun mode.
- the change in the negative pressure to act on the thrust resistance and / or the pull resistance is further preferably carried out by varying a secondary air opening and / or changing the speed of a fan wheel.
- a secondary air opening can be provided in the suction nozzle, the opening cross section of which is changed more or less depending on the measured load.
- the change in the negative pressure can also take place by electrical control of the motor power or speed of the fan wheel generating the suction air volume flow.
- the vacuum can also be changed by regulating the suction power cross section, for example by controlling a rotary flap in the suction line. The distance between the suction nozzle base and the floor to be cleaned can also be varied to change the vacuum.
- the method according to the invention increases the ease of use nes vacuum cleaner considerably.
- the suction power in pushing and pulling operation can be kept constant on a wide variety of surfaces (carpets of different densities or hard floors), which means that a simple and sensible force limitation with an automatic function is achieved for the user.
- Next is an indirect identification of the floor coverings using existing physical parameters or the use of special measuring sensors such. B. vacuum sensors, etc. conceivable, which parameters can optionally also be used for thrust resistance regulation.
- the invention further relates to a vacuum cleaner with a suction nozzle and a motor-driven fan wheel for generating a suction-air volume stiOm, through which a negative pressure is created in the suction nozzle, a force measuring device being provided in the vacuum cleaner, for example a vacuum cleaner handle is to determine a force load that ultimately has an effect on the user as thrust or tensile resistance, which in any case determines a compressive force in overrun mode.
- a vacuum cleaner of the type in question is known from the aforementioned W097 / 26819 A2.
- a vacuum cleaner is described there, which has sensor means which respond to the respective direction of movement (forward, backward) of the suction nozzle and furthermore has switching means which vary the vacuum or the air flows in the area of the suction nozzle as a function of the detected direction of movement ,
- the sliding resistance be acted upon automatically depending on the force load detected.
- the thrust resistance being acted on as a function of the detected value, which ultimately has a positive effect for the user.
- the airflow window is automatically set accordingly, so that the User always receives an optimal cleaning result related to the surface and the pushing force does not increase unnecessarily.
- the essence of the invention is the detection of the pushing force of the suction nozzle and the feedback on suitable devices for adapting the thrust resistance.
- the force load is measured in overrun mode and the thrust resistance is leveled. It is further preferred that the force load is measured both in the pushing and pulling operations and as a result both the pushing and pulling resistance is regulated to approximately the same level.
- the action takes place through a change in the negative pressure in the suction nozzle, with a measure being chosen with regard to the change in negative pressure which achieves an appropriate, constant force load for the user with an optimal cleaning result, in particular related to the background.
- This proves to be particularly advantageous in that, depending on the type of carpet, only certain maximum volume flows are required for carpet cleaning in order to optimally clean the carpet. Higher volume flows would only generate higher pushing or pulling forces that the user does not want.
- a constant adaptation of cleaning performance and force load can be achieved, whereby in addition to the nature of the floor to be cleaned, further parameters for variation can also be consulted, such as the type and operating state of the suction nozzle and / or Pressure load by the user, for example, via the suction pipe on the suction nozzle.
- the force load which affects the user as thrust or tensile resistance, can be measured in the area of an actuating rod, for example in the area of a suction pipe or a handle of the vacuum cleaner.
- a force sensor is located in the power flow chain, for example, between the handle of the vacuum cleaner for hand vacuum cleaners or the suction pipe for cylinder vacuum cleaners and the suction nozzle.
- This force sensor registers the pushing force in both pulling and pushing operations.
- the measured A variable serves as an input signal to a control system which, for example, influences the vacuum at the suction nozzle in such a way that the pushing force corresponds to a predetermined target.
- the force load in the suction nozzle can be measured. There is also the possibility of changing the force in the area of a joint between the vacuum cleaner and
- Measure suction nozzle in addition, also at other places in the area of the vacuum cleaner or suction nozzle that are influenced by force.
- the change in vacuum is carried out in proportion to the measured pressure force.
- the change in vacuum is carried out disproportionately or disproportionately to the measured pressure force.
- the shear and / or tensile resistance can also be regulated to an appropriate level for the user by activating the traversing drive, even in the case of floors which, due to their design or because of the degree of soiling, have to be cleaned with an increased cleaning performance and thus with an increased vacuum ,
- the traversing drive can only be activated in overrun mode.
- the change in the vacuum for acting on the thrust resistance and / or the pull resistance is further preferably carried out by varying a secondary air opening and / or changing the speed of a fan wheel. Accordingly, an auxiliary air opening can be provided in the suction nozzle, the opening cross section of which is changed more or less depending on the measured load.
- the change in the negative pressure can also take place by electrical control of the motor power or speed of the fan wheel generating the suction air volume flow.
- a change in vacuum can also be achieved, for example, by controlling a rotary flap in the suction line to vary the cable diameter.
- a change in vacuum is achieved by changing the distance between the suction nozzle base and the surface to be cleaned. The force is primarily measured in the direction of the stick or suction tube, and accordingly in the direction of action. It is also conceivable to use a conversion to measure and use the force parallel to the ground.
- the measuring points in question are the vacuum cleaner handle on a hand-held vacuum cleaner, the suction pipe on a floor vacuum cleaner, the joint on the attachment, the coupling point to the vacuum cleaner, the connecting piece on the vacuum cleaner or also a point in the attachment or the suction nozzle that is influenced by force.

- the force measuring device can also consist of a spring-travel system with limit switches. In a further alternative embodiment it is provided that the force measuring device consists of a continuously operating signal transmitter.
- a combination of the various power sneezing devices is also conceivable.
- the force measurement can be carried out by means of a strain gauge arranged on a plastic part of the joint shell. Alternatively, the force is measured on a metal plate, which is inserted into a plastic part.
- a force shunt may be used, e.g. B. be used by means of a leaf spring.
- a spring-travel system using a potentiometer track or limit switches or, moreover, using an optical trigger is also conceivable.
- a kap aziti er sensor can, for example. be arranged between a suction port and the air duct.
- the change in the light intensity or the refractive index is measured via this.
- a detection of the path or the force is also set up via a spring-displacement system as an eccentric between a joint piece and chassis possible.

- a parking switch can be dispensed with by the configuration according to the invention.
- the force measuring device recognizes the rest position since there are no thrust or tensile loads.
- the rotating brush is therefore switched off automatically.
- the system can also be tared via this parking position.
- the park position is recognized and evaluated, the weight of the vacuum cleaner housing, the suction pipe and / or the suction hose acting on the suction nozzle or on the front attachment serving as tare weight.
- Taring is also possible in any other defined rest position and, moreover, also by averaging from the measured values for the forward and return stroke.
- the rotating brush can also be controlled with regard to the speed. It has proven to be particularly advantageous that the acquisition of gravimetric, precise measured variables is not absolutely necessary. Only changes to a system zero point need to be recorded and evaluated.
- the connected vacuum cleaner can also recognize which volume flow window is required for the optimal cleaning result via an electrical code in the attachment or suction nozzle.
- the type of carpet can also be recognized by means of a rotating brush in the suction nozzle. The speed of the brush on the carpet, the current consumption of this related motor or the wear of the bristles can be used as parameters.
- the parameters are measured when the brush is freewheeling and when in use on the floor, which achieves a calibration of the system.
- Hard floors can also be recognized and adjusted due to the free running of the rotating brushes.
- the individual limit values for the different floors are stored, for example, in a table of values in the respective front attachment and thus control the vacuum cleaner.
- regulation by default is also possible.
- the pushing force can be selected as the manipulated variable by the user. So z. B. the adjustment of the pushing force to different user groups (older, frail, etc.) possible.
- the solution according to the invention creates a vacuum cleaner with increased ease of use.
- the suction power in pushing and pulling operation can be kept constant on a wide variety of surfaces (carpets of different densities or hard floors), which means that the user can easily and sensibly limit the pushing force with an automatic function. Furthermore, an indirect identification of the floor coverings using existing physical parameters or the use of special measuring sensors such as B. vacuum sensors, etc. conceivable, which parameters can optionally also be used for thrust resistance regulation.

- the suction nozzle 2 has in the usual way a suction space 3 which extends transversely to the usual direction of movement (r, r ') and which is assigned to the end region of the suction nozzle 2 and is designed to cover almost the entire width thereof.
- the suction chamber 3 opens towards the floor 4 to be cleaned in a suction mouth 5.

- the suction chamber 3 or the suction mouth 5 is arranged upstream and downstream in each case one parallel to the suction chamber 3.
- These sealing elements 10 can be vertically displaced in a known manner. So they are lowered to seal the suction chamber 3 when cleaning hard floors and protrude beyond the suction nozzle floor 11 to the approximately sealing system on the floor 4 to be cleaned. In contrast, when cleaning a carpet, these sealing elements 10 are raised.
- the suction nozzle 2 has displacement wheels 12 in the rear area facing away from the suction space 3.
- a brush 15 which can be driven by an electric motor 13 integrated in the suction nozzle 2 is arranged in the suction space 3. This is designed as a brush roller, which rotates in the center of the suction chamber 3 and rotates about an axis oriented in the suction chamber extension. The bristles of the brush 15 protrude downward above the suction nozzle base 11 from the suction mouth 5 for the mechanical brushing of the carpet to be cleaned.

- the force measurement can also be carried out on a metal plate inserted in the plastic part.
- a force measurement can also take place via a spring-displacement system, which is arranged as an eccentric between the articulated receptacle 7 and the suction nozzle housing.

- the force measuring device 17 can also be provided in the area of a point in the suction nozzle 2 which is influenced by the force.
- the force load values detected by the force measuring device 17 are preferably detected and evaluated both in overrun in the direction of the arrow r and in the pulling operation in the direction of the arrow r 'by a control unit 23 arranged in the suction nozzle 2.
- This regulates the thrust resistance of the vacuum cleaner 1 as a function of the measured force load for example by changing the vacuum in the suction nozzle 2 or in the suction chamber 3.
- This vacuum change can take place by changing the speed of the suction / blower motor 16 in the vacuum cleaner 1.

If the bellows 33 is actively acted upon, the housing 31 is raised thereby and the distance between the suction mouth 5 and the floor 4 to be cleaned is increased. The negative pressure is reduced.
- the vacuum is reduced via the control unit 23, the constant measurement of the force load resulting in a constant adjustment of the thrust / pull resistance of the vacuum cleaner 1, and thus by varying the vacuum in the suction chamber 3.
- the travel wheels 12 of the suction nozzle 2 can be driven by an electric motor.
- the feed is automatically changed via the traversing wheels 12.
- the speed and / or the direction of rotation of the brush 14 arranged in the suction space 3 can also be influenced.

- the volume flow window can be narrowed for carpet cleaning. Depending on the type of carpet, only certain maximum volume flows are required. necessary to optimally clean the carpet. If higher volume flows and a correspondingly higher vacuum in the suction space 3 are absolutely necessary - which would also lead to an undesirable increase in the pushing forces for the user - the automatic use of the already indicated, electromotively driven traversing wheels 12 is conceivable, for example.
- the type of carpet can also be recognized in that parameters such as the speed and / or the current consumption of the electric motor 13 driving the brush 14 are recorded. Depending on the required accuracy, the parameters must be measured when the brush 14 is freewheeling and when it is in use on the floor 4. A calibration of the system is conceivable in this way.
