Definitions

  • the present invention relates to a method for determining the contamination of a shaving apparatus according to the preamble of claim 1 and an apparatus for carrying out the method according to claim 14.
  • JP 61-220 688 A1 a solution is known from JP 61-220 688 A1 in which the shaving head contamination by shaving dust is determined by means of optical methods.
  • the solution according to the invention has differences.
  • By evaluating the noise from at least one movable lower knife or upper knife of a shaving head of a shaving apparatus it is directly taken into account to what extent the shaving result can possibly be impaired by the soiling of the shaving apparatus. It has namely been shown in knowledge of the invention when carrying out tests that increasing contamination of the movable lower knife or upper knife of a shaving head leads to a change in the noise of this movable lower knife or upper knife when shaving. This change in noise can also be measured and evaluated accordingly. Knowing the invention, this can be explained by the fact that with increasing contamination of the movable lower knife or upper knife, the moving mass of this lower knife or upper knife increases. As a result, the natural frequency of vibrations of this movable lower knife or upper knife decreases. In the noise spectrum, the noise signal changes over frequency. The degree of soiling of the shaving apparatus can then be concluded from a change in this frequency-dependent noise signal.
  • the shaving dust which is loosely in the shaving head, does not directly affect the shaving result, but is detected in the optical method described.
  • the optical method is thus at best an indirect measure of how increasing soiling of the shaving head affects the shaving result. There must then be a certain correlation between the amount of loose shaving dust in the shaving head and the amount of sebum or shaving dust that is attached to the movable lower knife or upper knife. It can thus be seen that in the solution according to the invention a more direct detection of the contamination is carried out, which actually influences the shaving result.
  • the invention is defined by the method according to claim 1 and the device according to claim 14.
  • the solution according to the invention has the advantage that cleaning carried out in the meantime is also taken into account when determining the contamination.
  • the signal which indicates the need for cleaning is also output when the time has expired but cleaning has just been carried out.
  • the design of the method according to claims 2 and 3 relates to different frequency ranges in which a signal evaluation for determining the contamination of a shaving apparatus is possible.
  • the criterion is formed so that it can be determined with comparatively little effort.
  • frequency filtering can be carried out on the design of the measuring system.
  • the signal can also be recorded without filtering and the corresponding frequency can then be found during signal evaluation.
  • a particular type of razor i.e. to the movable lower knife or upper knife of the shaving head of this type of shaver
  • the setpoint is fixed. No adjustments to this setpoint are made to the individual shavers, i.e. the individual movable lower knife or upper knife of the shaving head of this type of shaver.
  • the method can be carried out overall with little effort.
  • the individual movable lower or upper knives of the shaving head of different shavers of the same type of shaver can have different setpoints.
  • this type of determination of the target value can take place when the user starts up the device. This can also be done if commissioning consists in the fact that the shaver is subjected to a test run in the course of a quality check.
  • the method according to claim 8 also takes into account if at least the movable lower knife or upper knife of the shaving head is replaced during the life of the shaving apparatus. Due to the manufacturing tolerances mentioned, it may be necessary to assign a different setpoint to the new part than to the old part. If the movable lower knife or upper knife has been removed, it may also be that this was done in order to clean the movable lower knife or upper knife and to reinsert it after cleaning. In this case, the newly determined setpoint will correspond to the previous setpoint.
  • a criterion can be derived from the deviation of the newly determined target value from the previous target value as to whether such an exchange has taken place in order to then update the display, for example. This criterion can consist, for example, that the deviation exceeds a certain threshold value.
  • the removal in the method according to claim 9 can be derived from the evaluated signal itself without any sensor effort.
  • the movable lower knife or upper knife has at least been cleaned, if not replaced.
  • the latter can possibly be differentiated by the extent of the sudden change. If the change is just so large that the criterion again corresponds to the previous setpoint, it can be concluded that the cleaning is involved. If the sudden change is so great that the criterion deviates by a certain minimum amount from the previous target value, it can be concluded that the movable lower knife or upper knife has been replaced.
  • the user is given information that a cleaning of the shaver is necessary.
  • the haptic perceptibility can be given, for example, by a characteristic speed variation of the motor of the shaving apparatus.
  • the method according to claim 12 advantageously ensures that the user can also perceive the signal. If the signal is only output during the operation of the shaver, it can happen that, for example, an optical signal is covered by the hand of the user of the shaver. This optical signal can be more easily perceptible if the shaver is put down after use or placed in a special holder.
  • a shaving apparatus in a holder which either represents a cleaning device for the shaving apparatus at the same time or is coupled to such a cleaning device.
  • a cleaning device for the shaving apparatus at the same time or is coupled to such a cleaning device.
  • a controller in the shaver can be connected to the cleaning device via the holder in such a way that signal transmission is also possible.
  • the size to be evaluated is measured directly by attaching the structure-borne sound sensor to the movable lower knife or upper knife. Any disturbing noises caused by the engine running are so strongly attenuated by the transmission of the movement to the movable lower knife or upper knife that they no longer have any disruptive effects when evaluating the signal.
  • the device according to claim 15 serves to make a corresponding signal perceptible to the user.
  • the device according to claim 16 is used to correctly determine the setpoint even if the setpoint changes when an exchange of at least the movable lower knife or upper knife.
  • the shaving apparatus 101 has a housing in which, for example, there is an accumulator and the mains voltage is converted. There is also a motor in this housing, which can be designed as a DC motor. In the shown shaving apparatus 101, a lower knife 102 is driven by this motor, which is not shown in detail.
  • the shaving apparatus 101 shown in FIG. 1 has a shaving head which consists of the lower knife 102 and an upper knife (not shown in more detail).
  • This upper knife can consist of a shaving foil which is attached to the shaving apparatus 101 by means of a shaving foil carrier.
  • the moveable part of the shaving head ie the lower knife 102 in the example shown, is essential for the invention. For reasons of clarity, the rest of the part of the shaving head known to this extent has therefore not been shown.
  • the lower knife 102 is moved back and forth by the motor of the shaving apparatus 101 in accordance with the arrow 103. Together with the shaving foil installed during operation, the whiskers are cut off.
  • the lower knife 102 becomes dirty in that tallow and shaving dust settle on this lower knife 102. In the case of a certain degree of soiling, the shaving result is impaired.
  • a structure-borne noise sensor 104 can be attached directly to the movable lower knife 102.
  • the structure-borne noise sensor 104 can then be used to record the noises during shaving, it being possible to distinguish frequencies in the structure-borne noise area.
  • an airborne sound microphone 105 can also be provided.
  • the airborne sound microphone 105 can then be used to record the noises during shaving, it being possible to distinguish frequencies in the audible range.
  • the shaving apparatus 101 can have, for example, a microprocessor, by means of which e.g. the state of charge of the battery can also be determined.
  • the signal from the structure-borne noise sensor 104 or the airborne sound microphone 105 can be fed to this microprocessor and then evaluated accordingly in the microprocessor.
  • this airborne sound microphone 105 can be attached directly to the housing of the shaving apparatus 105.
  • the signal supply to the microprocessor, which is also located in the razor housing, is then simpler than when using a structure-borne sound transducer 104, in which the signal must be transmitted via the movable connection of the movable lower knife 102 to the razor 101, in order to use the airborne microphone 105 for the
  • a high-pass filter the corner frequency of which can be, for example, 10 kHz.
  • a piezoelectric film can be used as the structure-borne sound sensor 104.
  • the movable lower knife 102 is designed as a tubular knife block which is attached to a plastic carrier, the piezoelectric film can be introduced between this plastic carrier and the tubular knife block. Since the structure-borne noise sensor 104 is attached directly to the movable lower knife 102, disturbing running noises of the motor have a significantly lower effect here. The signal is therefore recorded immediately, without a disturbing background. For this reason, signal filtering can also be dispensed with under certain circumstances.
  • FIG. 2 shows a flow chart of a method for signal evaluation, with which the contamination of the shaving apparatus 101 can be derived.
  • step 201 the signal from the measuring system is recorded.
  • a frequency analysis of the signal is then carried out in step 202.
  • the signal can be broken down into its spectral components by means of the Fast Fourier transform. It is also possible to determine the power density spectrum. The frequency is then determined at which the spectral decomposition of the signal gives a maximum value. This frequency then corresponds to the natural frequency of the movable lower or upper knife.
  • this frequency is then compared with a nominal value of the natural frequency of the movable lower or upper knife.
  • This nominal value of the natural frequency corresponds to the natural frequency of the movable lower or upper knife in a clean shaving apparatus 101. If the determined natural frequency is smaller than the nominal value of the natural frequency by more than a certain threshold value, a transition is made to step 204.
  • step 204 it can be concluded that the natural frequency was lowered due to such heavy contamination that cleaning of the shaving apparatus 101 is necessary or at least sensible.
  • step 204 a signal is then generated which, for example, controls a display device which is perceptible to the user of the shaving apparatus 101 or which cleans the shaving apparatus 101.
  • step 203 If the check in step 203 showed that the natural frequency determined is not less than the desired value of the natural frequency by more than a certain threshold value, it can be concluded that no cleaning is necessary. The process can then be ended.
  • 3 shows a procedure for how the setpoint can be determined.
  • the setpoint for the movable lower or upper knife of a razor type is fixed. This procedure is very easy to carry out, because this setpoint only has to be stored in the microprocessor for a specific type of shaver.
  • the natural frequency is determined in step 301 when the shaving apparatus 101 is put into operation and this value of the natural frequency is stored in step 302 as a setpoint.
  • This setpoint is then used in the following with the currently determined natural frequency in the sequence according to FIG. 2.
  • Commissioning can be carried out as part of a functional test in the manufacturer's factory or it can be the first commissioning by the user.
  • tolerances of the movable upper and lower knives can also be compensated, which have an influence on the natural frequency.
  • the setpoint is also adapted here if the movable lower or upper knife is exchanged during the life of the shaving apparatus 101. The setpoint is then not held at a predetermined value.
  • step 401 it is checked in step 401 whether the movable lower or upper knife has been removed. If this is not the case, the process according to FIG. 4 is ended.
  • the natural frequency is first determined in step 402 and this value of the natural frequency is stored in step 403 as a setpoint.
  • This setpoint is then used in the following with the currently determined natural frequency in the sequence according to FIG. 2.
  • the new setpoint After the new setpoint has been determined in the method according to claim 4, it can be determined in accordance with the sequence shown in FIG. 5 whether the movable lower or upper knife has been replaced. It is also possible that the movable lower knife or upper knife has been removed in order to clean it and to reinsert it after cleaning. In this case, the newly determined setpoint will correspond to the previous setpoint. Depending on the extent of the change in the setpoint with the manufacturing tolerance, it is also conceivable, after the movable lower knife 102 or upper knife has been reinserted, to deduce whether the movable lower knife 102 or upper knife from the deviation of the newly determined setpoint is the same as before or whether a new lower knife 102 or upper knife was used.
  • step 501 It is therefore checked in step 501 whether the new target value deviates from the old target value by more than a predetermined threshold value. If this is the case, it can be concluded that a new movable lower or upper knife has been inserted. In this case, a counting device or another device is standardized in step 502, by means of which the need to replace the movable lower or upper knife is to be determined.
  • tolerances of the movable lower and upper knives can also be compensated for, which have an influence on the natural frequency.
  • the setpoint is also adapted here if the movable lower or upper knife is exchanged during the life of the shaving apparatus 101. The setpoint is then not held at a predetermined value.
  • the setpoint is determined during commissioning, as was explained, for example, in connection with FIG. 3.
  • step 601 it is checked in step 601 whether the natural frequency currently determined during operation has increased abruptly compared to the natural frequency during the last shave. It is therefore checked whether the currently determined natural frequency is greater than the natural frequency determined during the last shave by more than a certain amount. If this is not the case, the process according to FIG. 6 is ended.
  • This new setpoint is then used in the following with the currently determined natural frequency in the sequence according to FIG. 2.
  • the new setpoint After the new setpoint has been determined, it can also be determined whether the movable lower or upper knife has been replaced. It is possible that the movable lower knife 102 or upper knife has been removed in order to clean it and to reinsert it after cleaning. In this case, the newly determined setpoint will correspond to the previous setpoint. Depending on the extent of the change in the setpoint with the manufacturing tolerance, it is also conceivable, after a sudden change in the natural frequency in the sense of an increase in frequency, to deduce from the deviation of the newly determined setpoint from the previous setpoint whether the movable bottom knife 102 or Upper knife is the same as before or whether a new lower knife 102 or upper knife was used.
  • step 603 it is checked in step 603 whether the new setpoint deviates from the old setpoint by more than a predetermined threshold value. If this is the case, it can be concluded that a new movable lower or upper knife has been inserted. In this case, a counting device or another device is standardized in step 604, by means of which the need to replace the movable upper or lower knife is to be determined.
  • FIG. 7 shows an evaluation unit 701, which can be a microprocessor in the razor housing, for example.
  • This microprocessor can then, for example, output a signal to an output device 702 when the need to clean the shaving apparatus 101 has been recognized.
  • a signal can also be output when the need to change the movable lower or upper knife has been recognized.
  • the signal can be displayed to the user optically, acoustically and / or haptically - for example by clocking the speed. It is advantageous if the acoustic or optical signal is displayed to the user for a certain time after the shaving apparatus 101 has been switched off.
  • the cleaning device 801 into which the shaving apparatus 101 can be introduced. This is done, for example, in such a way that the shaving head of the shaving apparatus 101 is introduced downwards.
  • the evaluation unit 701 which is located in the shaving apparatus 101, can then output a signal via the mains connection of the shaving apparatus 101.
  • the cleaning device 801 is connected to the shaver 101 via this network contact of the shaving apparatus 101. This signal can thus be fed to the evaluation unit 701 of the cleaning device 801.
  • the cleaning device 801 has holding bolts 802 which hold the shaving apparatus 101 in an upper position when no cleaning is to be carried out and the cleaning device 801 is only to be used, for example, for storing the shaving apparatus 101.
  • these retaining bolts 802 are pulled back, for example by electromagnets, and the shaving apparatus 101 is brought into a lower position.
  • the cleaning device 801 starts operating, which may consist, for example, in that the cleaning liquid 803, which is in the cleaning device 801, is pumped around in order to clean the shaving apparatus 101.
