Definitions

  • the present invention relates to a method for determining the degree of filling of a arranged in a vacuum cleaner with a drive motor Staubabscheide- and collecting organ.
  • the invention also relates to a vacuum cleaner with a drive motor, a Staubabscheide- and collecting element and a device for detecting the degree of filling of Staubabscheide- and collecting organ.
  • the object is achieved for a generic method by an evaluation during operation of the vacuum cleaner determines the absolute and / or relative speed of the drive motor as the actual value, compared with a reference value for the speed and derived from the comparison an indicator value for the degree of filling.
  • the object is achieved for a generic vacuum cleaner by the device for detecting the degree of filling of Staubabscheide- and collecting element has a transmitter, determined by a suitable software-controlled circuit, a current speed of the drive motor as a relative and / or absolute actual value, a reference value accessible, a difference and / or a quotient between the actual value and the reference value determinable and from the certain reference and / or the specific quotient, a value for the degree of filling of the fine dust filter can be derived.
  • the fine dust filter is a filter that is connected downstream of a first separator in the vacuum cleaner because it still allows particles of a certain size to pass downwards.
  • conventional dust bags or one or more stages of a cyclone separator can be considered as first separators.
  • the fine dust filter can also be designed to accommodate larger amounts of dust, for example, 200 g or more, see for example WO 2007/022959 A1 ,
  • a vacuum cleaner is an arrangement of a series connection of a plurality of flow resistances.
  • Variable resistances are the flow resistance of the floor nozzle moving floor nozzle and the floor covering itself, the flow resistance of the dust bag and the flow resistance of the exhaust filter. Since the flow resistance of the vacuum cleaner (without filter) and a possibly used cyclone essentially have a fixed character, it is advantageous to choose a time for the speed measurement, in which the influence of the variable resistances is minimized.
  • a measuring time for example, a time directly after turning on the vacuum cleaner or shortly before turning off the vacuum cleaner.
  • Other measuring times are also possible, in which case, if possible, a favorable time depending on other operating parameters should be selected to increase the measuring accuracy.
  • the absolute value can be taken as the actual value.
  • a suitable sensor for speed detection is advantageous. If an electronically commutated motor is used, the position of the rotor can be determined by a position sensor or mathematically from the course of the motor current. Then it is easy to determine the speed from the time change of the position of the rotor, so that in this type of engine no additional speed sensor is required.
  • a relative speed value can also be determined as the actual value and used to compare this with a reference value. The relative speed value is formed by offsetting a measured actual value with other parameters, in particular with the speed value when the dust collecting / collecting element is empty, wherein the calculated relative value contains an evaluable statement about a current speed level of the drive motor.
  • the reference value may be a value previously determined to be the actual value, or it may be a stored value representative of either the empty state of the dust collecting and collecting device or a certain filling level determined by the transmitter is to be detected. Depending on whether an absolute and / or relative actual value for the rotational speed is used, a corresponding absolute and / or relative value can also be used for the reference value.
  • the transmitter can establish a greater-than, less-than, and an equal relation between the values.
  • the comparison can also be made by calculating a quotient that maps a ratio between the actual value and the reference value.
  • the actual value may also be subtracted from a reference value to determine from the difference whether a critical condition has been reached or not.
  • the evaluation electronics can derive an indicator value for the degree of filling from the comparison of the actual value with the reference value.
  • the indicator value can in turn be stored, used as a signal for a display or used as a control variable for the control of the vacuum cleaner.
  • the evaluation electronics are provided with suitable software in order to be able to carry out the comparison according to the invention and the evaluation.
  • the appropriate software makes it possible to determine the current speed of the drive motor as a relative and / or absolute actual value, to access a reference value and to determine a difference and / or a quotient between the actual value and the reference value.
  • the appropriate software can also be the difference and / or the derive a value for the degree of filling of the fine dust filter from certain comparisons.
  • the dust collecting and collecting organ the degree of filling of which can be determined by the transmitter, to a fine dust filter.
  • the fine dust filter serves the purpose of filtering out such dust particles from the air stream flowing through the vacuum cleaner, which, although they have passed the first filter stage, are not supposed to escape from the vacuum cleaner again. These may be, in particular, particularly fine dust particles and pollen, which should be removed as comprehensively as possible from the cleaned space during a suction process.
  • the pore size of the fine dust filter should be such that the corresponding particle sizes of a fine dust are also retained in the fine dust filter.
  • the absorption capacity of the fine dust filter can be designed according to the vacuum cleaner concept and after the planned normal service life of the fine dust filter.
  • the fine dust filter is arranged downstream of a centrifugal separator.
  • the combination of a centrifugal separator with the inventive measurement of the degree of filling of the particulate matter filter is particularly suitable because the resistance of the centrifugal separator is virtually unchanged from its degree and the resulting possibility of failure in determining the degree of filling of the particulate filter remains correspondingly low. With this combination, the degree of filling of the fine dust filter can accordingly be determined very precisely by the comparison according to the invention.
  • the reference value for the rotational speed of the transmitter from a memory can be read and / or read into a memory. Since the reference value for the rotational speed can be helpful for one or more later comparisons for the evaluation electronics, it makes sense to be able to read and / or read it from a memory.
  • the reference value does not always have to be the same size, but can vary and assume different sizes.
  • the memory makes the reference value for the transmitter immediately available when needed. It is equally advantageous if the evaluation electronics can read the reference value into a memory on its own.
  • the electronics recognizes that another reference value is not or no longer usable, or if, according to the evaluation method according to the invention, one or more new reference values are formed by one or more comparisons, these are only available for subsequent comparisons and evaluations if the reference value or values can also be stored by the evaluation electronics. It is also possible that the transmitter with operates different reference values, for example a plurality of reference values, which are stored in a historical sequence to document the filling history, and / or a plurality of reference values, which are accessible for different operating conditions and / or operating parameters.
  • the evaluation electronics take into account a second process variable for determining the indicator value.
  • a process variable various values can be taken into account, such as, for example, the engine power, a negative pressure value at a location of the vacuum cleaner, a noise value, a characteristic value from a characteristic map or another process variable.
  • the second process variable can be used for a plausibility check of the indicator value determined according to the invention, or the second process variable is otherwise input into the method in order to derive an indicator value for the filling level from the comparison of the actual value for the rotational speed of the drive motor with the reference value.
  • the second process variable may also provide information about the operating mode in which the vacuum cleaner is currently located.
  • the vacuum cleaner at the time of determining the actual value for the speed of the drive motor was controlled to a lower than the maximum possible speed, which may affect the result of the comparison of the actual value with the reference value.
  • the reference value corresponds to the actual value of the rotational speed of the drive motor with empty Staubabscheide- and collecting member or a target value for the speed of the drive motor, in particular with empty Staubabscheide- and collecting organ.
  • the evaluation electronics can easily make a statement about the current filling level. If differences between the two values result from the comparison of the reference value thus defined and the actual or desired value, this difference can be regarded as an indicator of the degree of filling of the dust-collecting and collecting element.
  • the value of the indicator and / or the result of the evaluation can be communicated to an operator via a corresponding display.
  • the display may be optical and / or acoustic signals, an alphanumeric display on a display and the like.
  • a plurality of reference values correlating to different power levels of the drive motor are available for the evaluation electronics. Depending on which power stage of the drive motor of the vacuum cleaner currently operated In this way, it is ensured that the actual value for the current rotational speed of the drive motor is compared with a reference value which corresponds to the current power level of the drive motor. In a simple embodiment of the invention, it is also possible that only for one power stage of the drive motor, a comparable reference value is present and the reference value for the other power levels consists of an error message.
  • the actual value when switching on the vacuum cleaner can be determined.
  • the transmitter automatically switches when switching on the vacuum cleaner in an evaluation mode in which an actual value for the absolute and / or relative speed of the drive motor is determined.
  • This point in time is particularly favorable for the determination of an actual value, because it is unlikely that high levels of interference will occur immediately when the vacuum cleaner is switched on, which results from the variable flow resistances of the floor nozzle or the floor covering itself moving on the floor covering.
  • the actual value of the absolute and / or relative speed of the drive motor can be determined even when switching off the vacuum cleaner by the evaluation switch when you press the off button in an evaluation mode in which prior to switching off the drive motor still briefly Actual value for the speed is determined.
  • the resulting time delay in the shutdown of the vacuum cleaner is barely perceptible to an operator time.
  • an actuator is controllable for determining the actual value and / or the reference value of the evaluation, with which an opening for supplying secondary air is to open and / or the main flow is closable.
  • the drive motor can suck the supply air from the opening directly into the Staubabscheide- and collecting organ.
  • error influences that can result from variable resistances can be at least partially or completely eliminated.
  • a corresponding effect is obtained if, alternatively or additionally, the main flow path for the intake air is closed by the actuator.
  • a Fineströmungsweg for the suction air is required with which a possible error-free amount of suction air can be brought to the Staubabscheide- and collecting organ.
  • the evaluation determines the difference between the actual value and the reference value and stores the difference in a memory until the determination of a new actual value.
  • the evaluation electronics feed the indicator value to a display device.
  • the Staubabscheide- and collecting organ has an individual marking that can be evaluated by the transmitter.
  • an individual identifier an individual number can be provided at which it is recognizable for the evaluation electronics at a query time, whether an old fine dust filter is still inserted or whether a new fine dust filter has been inserted.
  • the number can for example also be stored in a bar code or a chip with a reading field or transmitted as a transponder signal from Staubabscheide- and collecting organ to the transmitter when the transmitter needs the number.
  • a hologram can be used, which would serve as a certificate of authenticity at the same time.
  • the individual identification may also or additionally consist of a numerical value which can be processed by the evaluation electronics as a reference value and / or as a desired value. If the evaluation electronics detects that a new individual identification is present, it can conclude that, for example, a dust bag and / or a fine dust filter has been replaced, which in turn can be a reason for making a new reference measurement for a new dust bag and / or fine dust filter to obtain a new reference value, and / or to re-monitor the course of the actual value in order to derive conclusions about the degree of filling.

  • the actuator 8 is arranged in the flow direction of the suction air through the vacuum cleaner 1 seen before the fine dust filter 3.
  • the Nachorder the actuator 8 behind the centrifugal separator 2 ensures that the secondary air 10 can flow without disturbing influences by other components of the vacuum cleaner 1, in particular Staubsammelorgane, in the fine dust filter 3 and from there into the downstream fan 5. From the blower 5, the sucked air is blown back to the outside air, as needed with an additional blow-out. Depending on the degree of filling of the fine dust filter 3, more or less air can be drawn through the fine dust filter 3 by the blower 5 for the same power. The fuller the fine dust filter 3 is, the less air flows at the same drive power of the drive motor 4 through the fine dust filter 3 through, and because of the lower air flow capacity of the fan 5 this runs at a then increased speed. The speed of the fan 5 increases the more, the more the fine dust filter 3 is full.

  • the circuit in the determination mode can be triggered manually, automatically - for example via a time clock - or by a signal of the transponder receiving device 13 described above.
  • the absolute and / or relative speed of the drive motor can be determined as the actual value after switching on the drive motor 4. Since the empty particulate matter filter 3 or the empty Staubabscheide- and collecting organ of the suction air flowing through hardly opposes resistance, the fan 5 must provide a relatively high flow rate, whereby the speed of the drive motor 4 is pressed.
  • the measurement of the rotational speed of the drive motor 4 is performed in a power stage which is reproducible for later determination and evaluation processes.
  • the actual value can be determined for example in a higher or the maximum power level of the drive motor 4, because here the speed differences are clearly visible.
