  • the invention has for its object to provide an electrically operable floor care device that is improved over the prior art.
  • methods for the energy-saving operation of floor care devices are to be improved.
  • the object on which the invention is based is achieved by a floor care device according to claim 1, by a floor care device according to claim 12 and by energy saving methods for a floor care device as set out in claims 11 and 13.
  • a floor care device in the sense of the invention is a household appliance which can be operated electrically, comprises a motor and can be used for floor care.
  • a floor care device is an electric polishing machine, an electric steam cleaner or an electric parquet sanding machine.
  • a floor care device in the sense of the invention is a vacuum cleaner.
  • a desired operating power means the power to which a motor of a floor care device can be variably regulated by the user in order to individually determine the power, the volume or the energy consumption of the floor care device, taking into account, for example, the surface to be treated.
  • the desired operating power can usually be regulated by means of a handle in various stages or continuously from a minimum possible operating power to a maximum possible operating power which corresponds to the smallest possible or maximum operating power of the engine. The user can therefore choose from two or more possible desired operating services with which the motor of the floor care device is to be operated as desired.
  • Switching on the motor of the floor care device means the process that the user carries out by actuating a switch-on device, for example a toggle switch or pressure switch. Switching on the motor of the floor care device activates the motor by closing its operating circuit and thus puts the floor care device into the operating state.
  • a switch-on device for example a toggle switch or pressure switch.
  • an automatic operating power is to be understood as meaning an operating power of the engine that is started automatically when the engine is switched on, without any further measures being necessary apart from actuating the switch-on device of the floor care device.
  • the automatic operating power is thus automatically set by the automatic power control when the motor of the floor care device is switched on, so that the motor is then operated with this automatic operating power until further notice.
  • the subject matter of the invention and the corresponding methods can, for example, increase the ease of use because, after switching on, a frequently required power is automatically activated as an automatic operating power.
  • the engine can also be started with a particularly low output, for example, in order to save energy.
  • the automatic power control thus acts like a starting current limiter.
  • the maximum power of the engine is rarely actually needed. However, the user often leaves the desired operating performance at the highest selectable value, mostly for convenience. In other cases, medium power is regularly required, but changing surfaces occasionally cause the user to exceed or fall below this medium power using the handle.
  • the floor care device can be easier and more convenient to use if it always provides medium power after switching on and only minor adjustments have to be made using the handle. The method according to the invention and the floor care device according to the invention can thus, for example, in particular reduce the power consumption and make the usability of the vacuum cleaner more convenient. In addition, the service life of the handle and the associated control electronics can be increased because it has to be adjusted less frequently.
  • the automatic operating power is preferably an economy operating power which falls below the desired operating power manually selected by means of the handle. In this way the power consumption of the floor care device can be reduced. Users often leave the desired operational output at a maximum value or at least at a very high output value, for example at 80% of the maximum output. However, lower performance is often sufficient to fulfill the desired work order. Falling below the desired operating power manually selected by means of the handle can thus save electricity without, however, necessarily leading to noticeable performance losses.
  • the automatic operating power can also be selected such that it exceeds the desired operating power. This can be desirable, for example to always provide the highest possible performance immediately when the engine is switched on. If the automatic operating power and the desired operating power are the same, in particular happen to be the same, the automatic power control preferably has no effect.
  • the floor care device is a vacuum cleaner and the motor is an electric motor of a vacuum cleaner fan.
  • Vacuum cleaners are very common floor care devices. Due to their widespread use, energy-saving and therefore environmentally friendly operation is particularly desirable. Especially the electric motors of the vacuum cleaner blower often have high performance values, so that measures like the one described here can lead to particularly strong savings in electricity consumption. This in turn can be a special purchase argument for the user.
  • a vacuum cleaner can be a canister vacuum cleaner, a table vacuum cleaner, a stand-up vacuum cleaner, a handheld vacuum cleaner, a vacuum robot or a stick vacuum cleaner. He can use bagless dust collection technology, for example use a vortex tube separator, or use a dust bag to collect the dust.
  • the automatic operating power with which the automatic power control is to operate the engine is defined as an absolute value.
  • the absolute value can be stored, for example, in an inexpensive memory chip with a low capacitance or by using an electrical resistor with a fixed resistance value.
  • the specified absolute value can be, for example, between 100 watts (W) and 1200 W.
  • An automatic operating power with an absolute value of 600 W is particularly preferred, preferably in connection with a maximum desired operating power of 2300 W. Thus, when the floor care device is switched on, over 75% of operating energy can be saved.
  • a single absolute value for the automatic operating power is provided regardless of the desired operating power set.
  • a plurality of absolute values are available depending on the desired operating power, for example in the form of an electronic table. Then, for example, each selectable desired operating performance value is assigned an individual automatic operating performance by means of a static or changeable table that can be called up.
  • the automatic operating power is determined in that it represents a fixed relative proportion of the desired operating power selected manually by means of the handle.
  • a relative portion can be stored in a memory as a percentage or as a multiplication factor over which the automatic operating power is calculated automatically based on the desired operating power.
  • a microprocessor which can calculate such calculations from the data required for this. If, for example, a desired operating power of 1000 W is set and a relative share of 1.5 times the desired operating power is specified for the automatic operating power, the desired operating power is ignored when the motor is switched on and the motor is automatically operated at 1500 W by the automatic power control.
  • Another option, for example to operate with a savings benefit, is as automatic power to be set when switching on a factor of 0.6 of the desired operating power selected manually by hand. If, for example, a desired operating power of 2000 W is selected, the floor care device is operated with only 1200 W when switched on by the automatic power control. 1200 W is a power value that has proven to be sufficient for many tasks so that the user can achieve a good effect, for example suction. For example, powers of 2000 W are unnecessarily high for conventional work, for example suction jobs, so that there is potential for saving energy in this regard.
  • the automatic operating power corresponds to between 10% and 80% of the desired operating power selected manually by means of the handle. Users tend to judge the performance of a floor care device, particularly a vacuum cleaner, based on operating noise. Therefore, there is a tendency to activate a very high engine power, which is noticeable by a high operating noise and also results in high energy consumption. It is therefore advantageous to activate a reduced power as an automatic operating power when the engine is switched on.
  • the automatic operating power is preferably between 10% and 50%, particularly preferably 25% of the desired operating power manually selected by means of the handle.
  • an automatic operating power of 600 W can be activated when switched on, either as an absolute value or as a value to be calculated with a fixed factor of 0.24 or 24%, based on the desired operating power.
  • the automatic operating power with which the automatic power control is to operate the motor automatically after the motor of the floor care device is switched on can be determined by the user. Some users may find it more desirable to be able to customize the automatic operating performance of the floor care device. For this reason, means can be present on the floor care device with which the user himself can determine the amount of the automatic operating power that is to pass over the desired operating power when the device is switched on. These means can be used, for example, to change an absolute value, edit value tables, or regulate resistances.
  • an operating element via which the automatic operating power can be set manually.
  • such controls can, for example, keypads, handle elements for potentiometers, rocker switches, push buttons, for example + / - Push buttons, or touch-sensitive displays.
  • the user can adapt the automatic operating power to his needs if necessary.
  • a USB connection, a Bluetooth connection, an infrared connection or a radio connection, that is to say generally wireless data connections, can also be present for the user to program the desired automatic operating power, for example by means of an external computer, a smartphone or a radio or infrared remote control.
  • the automatic power control is set up in such a way that, when the motor of the floor care device is switched on, it only transfers the desired operating power for the engine, which is manually selected by means of the handle, if the desired operating power, manually selected by means of the handle, of the maximum engine power which can be set by means of the handle corresponds.
  • the desired operating power was left at the maximum value by the user due to negligence, whereas, in contrast, a reduction made by the user can indicate the desire to have the desired operating power of the engine available as soon as it is switched on.
  • the minimum operating power or any other desired operating power set can also be interpreted by the automatic power control as an indication that the automatic operating power for the motor should only pass over the desired operating power selected with the handle when this particular power is switched on.
  • the floor care device is set up so that a desired operating power selected manually by the user by means of the handle after the motor of the floor care device is switched on passes over the automatic operating power automatically set by the automatic power control when the floor care device is switched on, so that the motor then operates with this desired operating power becomes.
  • the user can easily deactivate the automatic operating power again if he deems this necessary, that is, he wants to have a different operating power than the automatic operating power.
  • a push button, a switch or another separate actuating means can also be present, for example on a housing part or, in particular in the case of a vacuum cleaner, on a suction pipe arrangement which comprises a suction pipe and a suction hose, and in particular on a handle of the suction pipe arrangement.
  • a push button, a switch or another separate actuating means can also be present, for example on a housing part or, in particular in the case of a vacuum cleaner, on a suction pipe arrangement which comprises a suction pipe and a suction hose, and in particular on a handle of the suction pipe arrangement.
  • actuation in order to control the automatic power control, in particular before the power is switched on
  • the automatic power control does not override the desired operating power, for example in the form of a toggle switch.
  • the handle for selecting the desired operating power can preferably be moved elastically beyond the selectable maximum position of the desired operating power. For example, the user does not have to first manually lower the desired operating power and then regulate it up again in order to bypass the automatic operating power after switching on the engine and to arrive at the maximum possible desired operating power.
  • the elastic outward movement can also serve to activate a short-term turbo mode for the engine, in that the engine is operated for a limited period above the maximum power that can be selected with the handle.
  • the handle can be designed such that it can be moved beyond a preselectable maximum position against a bias, for example caused by an elastic element, and automatically returns to the maximum position when the handle is released by the restoring force of the elastic element.
  • the handle for selecting the desired operating power is preferably designed as a rotary controller.
  • Rotary controls are a particularly preferred embodiment because they can simply be connected to a rotary potentiometer for regulating the output of the motor. Simple ways are also known to the person skilled in the art to make such a rotary controller elastically rotatable beyond its maximum rotational position, for example by means of a spring which is arranged within an operating cap of the handle.
  • a linear controller a keypad, a touch-sensitive display, rocker switch or one or more push buttons could also be used as a handle.
  • the handle for selecting the desired operating performance allows a continuous selection of a large number of desired operating performance.
  • a handle is preferred which allows a stepless power variation over the entire possible power range of the engine.
  • Appropriate handling has already been mentioned above, for example rotary or linear regulators.
  • a step-by-step selection of the desired operating power can also be offered, for example three power levels, which can be controlled, for example, by a rotary or linear regulator that locks in discrete positions. In this way, too, selection from two or more desired operating services can be made possible.
  • the floor care device is a canister-type vacuum cleaner (not shown).
  • the vacuum cleaner can be operated electrically and accordingly has a vacuum cleaner fan which can be driven by an electric motor.
  • the vacuum cleaner has a detachably connectable suction tube arrangement, comprising a suction hose and a suction tube, through which dust can be sucked off from a surface by means of the vacuum that can be generated by the vacuum cleaner fan. The dust is then received in a housing space of a housing of the vacuum cleaner within a dust bag and stored until further notice.
  • a handle for manual selection of one of several desired operating services of the electric motor for the vacuum cleaner fan is arranged on the housing of the vacuum cleaner.
  • the vacuum cleaner thus comprises several desired services.
  • the handle is designed as a rotary control and allows a stepless selection of the desired operating power of the electric motor.
  • the maximum selectable desired operating power is 2000 W and the minimum selectable desired operating power is 1000 W. Accordingly, any power between 1000 W and 2000 W can be set as the desired operating power by rotating the control dial.
  • the corresponding power of the motor is activated in a manner known per se by means of a rotary potentiometer which is operatively connected to the handle.
  • the housing includes an automatic power control for the electric motor.
  • the automatic power control automatically operates the electric motor when the vacuum cleaner is switched on with a power that passes and falls below the desired operating power manually selected using the handle.
  • the automatic power control is implemented, for example, as an electronic circuit that includes an automatic power controller, a microprocessor and an electronic memory.
  • the manufacturer stores a multiplication factor in the electronic memory, with which the microprocessor can calculate an automatic operating power from the desired operating power selected with the handle as soon as the vacuum cleaner is switched on. This is then activated via the automatic power regulator on the vacuum cleaner fan.
  • the numerical value 0.5 is stored in the memory by the manufacturer as the multiplication factor. This corresponds to an automatic operating performance of 50%, based on the selected desired operating performance.
  • the microprocessor obtains the multiplication factor from the memory, for example via a resistance measurement, the set desired power value and via a data connection, and calculates the automatic operating power to be set from these values. If, for example, a desired operating power of 2000 W is preset, an automatic operating power of approximately 1000 W is automatically calculated from this value when the vacuum cleaner is switched on using the multiplication factor 0.5, and the motor is then operated immediately with this lower power, which can save energy.
  • the housing of the vacuum cleaner has suitable input means, in this case a +/- key with two push buttons.
  • An LC display is adjacent to this arranged, which among other things can display the multiplication factor of the automatic power control. If the user presses the respective buttons, he can vary the multiplication factor, for example, in tenths of a step between 0.1 and 1.5.
  • the vacuum cleaner is switched on, the desired operating power is then bypassed and the vacuum cleaner fan is operated at 1500 W, for example, if the user has set the multiplication factor to 1.5 using the push buttons and set the handle to a desired output value of 1000 W in the period before the vacuum cleaner was switched on has been.
  • an absolute value is defined in the memory as the automatic operating power and there are no input means available to change this absolute value by the user.
  • the handle makes it possible to select a desired operating power between 800 W and 2000 W.
  • the specified absolute value for the automatic operating power is 800 W.
  • the handle for selecting the desired operating power is designed such that it can be moved elastically beyond the selectable maximum position of the desired operating power.
  • the handle is provided with a spring mechanism, which causes the control dial to be turned past the maximum position against a bias and then automatically returns to the maximum position after being released. If the user wants to deactivate the automatic operating power again after switching on, if the rotary control is already at the maximum position, the user only has to move the rotary control elastically beyond the maximum position and the motor is then immediately switched from the possibly reduced automatic operating power to the maximum desired operating power.
  • the user switches ( Fig. 1 ) first turn on the motor of the floor care device (step A01). This is done by pressing a button that closes a circuit so that the engine is started.
  • the automatic power control is also activated by pressing the push button. As described above, it is set up to bypass a desired operating performance set earlier by means of a handle. Accordingly, it operates the engine with an automatic operating power (step A02).
  • the automatic operating power is defined in a memory as an absolute value. In this case it is 700 W.
  • the motor of the floor care device is therefore operated at this stage with 700 W of power, regardless of which desired power value had been selected by the user before switching on.
  • the user operates the handle and changes the desired operating performance.

  • the automatic power control is thereby bypassed (step A04).
  • the engine is then operated with the desired operating power selected manually by means of the handle (step A05).
  • the handle was set to a desired operating power of 1500 W before the vacuum cleaner was switched on, the vacuum cleaner was automatically operated at 700 W after switching on because the automatic power control has overridden the desired operating power, and then the user has a desired operating power of using the handle 1200 W set, which in turn has overridden the automatic power control and the engine is finally operated with the desired operating power of 1200 W.
  • a second procedure is the floor care device, again a vacuum cleaner, initially in the operating state.
  • the user sucks off a deep-pile carpet and needs a high suction power. Therefore, the user operates the motor of the floor care device with a desired operating power that corresponds to the maximum selectable motor power by moving the handle to the maximum position (step B01). In this case, this is an output of 2400 W.
  • the user then completes the suction job and switches off the vacuum cleaner (step B02). At a later time, he wants to vacuum up another deep-pile carpet. To do this, he switches the vacuum cleaner on again (step B03). At this point, the handle is still in the maximum position.
  • the automatic power control By pressing a switch on the vacuum cleaner, however, the automatic power control first becomes active and operates the motor with a saving operating power as automatic operating power, for which in this case a factor of 0.25 times the set desired operating power is specified, i.e. only with 800 W.
  • the manual The desired operating power set is therefore skipped and undercut (step B04).
