The hair removal apparatus includes a housing adapted to be held in the hand, a mechanically working hair removal device and a motor for driving the hair removal device.

Description

Die Erfindung betrifft ein elektrisches Haarentfernungsgerät. Weiterhin betriff die Erfindung ein Verfahren zum Entfernen von Haaren von der menschlichen Haut.The invention relates to an electric hair removal device. Furthermore, the invention relates to a method for removing hair from the human skin.

Elektrische Haarentfernungsgeräte werden häufig mittels eingebauter Batterien, insbesondere wieder aufladbarer Batterien, betrieben. Dadurch kann vermieden werden, daß die Handhabung der Haarentfernungsgeräte durch Kabel behindert wird. Da die Speicherkapazität der Batterien begrenzt ist, ist eine möglichst effiziente Nutzung der gespeicherten elektrischen Energie wünschenswert. Ein großer Teil der für den Betrieb der Haarentfernungsgeräte aufgewendeten elektrischen Energie wird nicht unmittelbar für die Entfernung der Haare genutzt, sondern geht beispielsweise durch Reibung im Antriebsstrang der Haarentfernungsgeräte verloren. Dies bedeutet, daß sich beim Betrieb von Haarentfernungsgeräten auch dann ein erheblicher Verbrauch an elektrischer Energie ergibt, wenn keine oder nur wenige Haare entfernt werden.Electric hair removal devices are often operated by means of built-in batteries, especially rechargeable batteries. This can be avoided that the handling of the hair removal devices is hindered by cables. Since the storage capacity of the batteries is limited, the most efficient use of stored electrical energy is desirable. Much of the electrical energy used to operate the hair removal devices is not immediately used to remove the hair but is lost, for example, by friction in the driveline of the hair removal devices. This means that the operation of hair removal equipment even then results in a significant consumption of electrical energy, if no or only a few hairs are removed.

Um den Energieverbrauch in Grenzen zu halten und eine ausreichende Haarentfernung zu erzielen, werden Haarentfernungsgeräte häufig für im Durchschnitt zu erwartende Betriebsbedingungen ausgelegt. Dies führt allerdings dazu, daß die Haarentfernungsgeräte im Leerlauf, d. h. wenn keine Haare entfernt werden, Vibrationen und Geräusche verursachen und unter Vollast, d. h. wenn sehr viele Haare entfernt werden, eine unzureichende Funktion zeigen. Diesem unerwünschten Verhalten kann durch eine Steuerung der Drehzahl des Antriebsmotors der Haarentfernungsgeräte entgegengewirkt werden.In order to limit energy consumption and achieve adequate hair removal, hair removal devices are often designed for the average expected operating conditions. However, this leads to the hair removal devices idle, d. H. if no hair is removed, cause vibration and noise, and at full load, d. H. if a lot of hair is removed, show an insufficient function. This undesirable behavior can be counteracted by controlling the speed of the drive motor of the hair removal devices.

So ist aus der DE 42 01 027 A1 und der US-PS 5,367,599 ein elektrischer Rasierapparat bekannt, der abhängig vom Laststrom des Motors auf eine hohe oder geringe Bartdichte schließt. Die Ansteuerung des Motors erfolgt dann auf Basis der ermittelten Bartdichte. Bei einer geringen Bartdichte wird der Motor mit einer niedrigen Drehzahl und bei einer hohen Bartdichte mit einer hohen Drehzahl betrieben.So is out of the DE 42 01 027 A1 and the U.S. Patent 5,367,599 an electric razor is known which closes depending on the load current of the motor to a high or low density. The motor is then controlled on the basis of the determined density of the beard. At a low density of the bark, the engine is operated at a low speed and at a high density of barbs at a high speed.

Aus der EP 0 719 202 B1 ist ein Rasierapparat mit einem Elektromotor bekannt, dessen Geschwindigkeit von einer vorwärtsgekoppelten Regeleinheit als Funktion mindestens einer physikalischen Größe variiert. Die physikalische Größe ist mittels eines Aufnehmers meßbar, der ein Tonsignal zur Ermittlung der pro Zeiteinheit geschnittenen Haare, die bislang verstrichene Rasierzeit oder eine Hautkontaktkraft erfaßt.From the EP 0 719 202 B1 For example, a shaver with an electric motor is known, the speed of which varies from a feedforward control unit as a function of at least one physical quantity. The physical quantity is measurable by means of a pick-up which detects a sound signal for determining the hair cut per unit time, the shaving time which has hitherto elapsed or a skin contact force.

Der Erfindung liegt die Aufgabe zugrunde, mit einem Haarentfernungsgerät bei einem geringen Energieverbrauch eine gründliche Haarentfernung zu erzielen.The invention has for its object to achieve a thorough hair removal with a hair removal device with low energy consumption.

Diese Aufgabe wird durch ein Haarentfernungsgerät mit der Merkmalskombination des Anspruchs 1 und durch ein Verfahren gemäß Anspruch 16 gelöst.This object is achieved by a hair removal device with the feature combination of claim 1 and by a method according to claim 16.

Das erfindungsgemäße elektrische Haarentfernungsgerät zum Entfernen von Haaren von der menschlichen Haut weist ein in der Hand haltbares Gehäuse, eine mechanisch arbeitende Haarentfernungseinrichtung mit einem Untermesser und einer Scherfolie oder mit rotierenden Pinzetten und einem Motor zum Antreiben der Haarentfemungseinrichtung auf. Die Besonderheit des erfindungsgemäßen Haarentfernungsgeräts besteht darin, daß eine Sensoreinrichtung zur Erzeugung eines Signals vorgesehen ist, das von der Geschwindigkeit abhängt, mit der die Haarentfernungseinrichtung bei der Haarentfernung über die Haut bewegt wird.The electric hair removal device of the present invention for removing hair from the human skin comprises a hand-durable case, a mechanical hair removal device having a lower blade and a shearing foil or with rotating tweezers and a motor for driving the hair removing device. The peculiarity of the hair removal device according to the invention is that a sensor device is provided for generating a signal which depends on the speed with which the hair removal device is moved over the skin during hair removal.

Ein Vorteil des erfindungsgemäßen Haarentfernungsgeräts besteht darin, daß durch eine Nutzung des Signals der Sensoreinrichtung ein geringer Energieverbrauch erreichbar ist und dennoch eine gründliche und hautschonende Haarentfernung möglich ist. Im Falle eines Batteriebetriebs ergibt sich gegenüber bekannten Haarentfernungsgeräten eine längere Batterielebensdauer oder es können Batterien mit reduzierten Abmessungen verwendet werden. Außerdem kommt es auch bei schnellen Bewegungen der Haarentfernungseinrichtung relativ zur Haut nicht zu einem schmerzhaften Ziehen an den Haaren. Ein weiterer Vorteil besteht darin, daß der Geräuschpegel und die Vibrationen beim Betrieb des Haarentfernungsgeräts insgesamt relativ niedrig gehalten werden können.An advantage of the hair removal device according to the invention is that by using the signal of the sensor device, a low energy consumption can be achieved and yet a thorough and skin-friendly hair removal is possible. In the case of battery operation results over known hair removal devices a longer battery life or it can be used batteries with reduced dimensions. In addition, even with rapid movements of the hair removal device relative to the skin, there is no painful pulling on the hair. Another advantage is that the noise level and the vibrations during operation of the hair removal device can be kept relatively low overall.

Die Sensoreinrichtung kann wenigstens einen drehbar gelagerten Rotationskörper aufweisen. Der Rotationskörper ist vorzugsweise so angeordnet, daß er in Rotation versetzt wird, wenn die Haarentfernungseinrichtung über die Haut bewegt wird. Weiterhin kann die Sensoreinrichtung einen Meßaufnehmer zur direkten oder indirekten Erfassung der Rotation des Rotationskörpers aufweisen. Auf diese Weise kann mit einfachen Mitteln die Geschwindigkeit der Haarentfernungseinrichtung relativ zur Haut erfaßt werden.The sensor device may have at least one rotatably mounted rotary body. The rotary body is preferably arranged to be rotated as the hair removal device is moved across the skin. Furthermore, the sensor device may have a measuring transducer for direct or indirect detection of the rotation of the rotary body. In this way, the speed of the hair removal device relative to the skin can be detected by simple means.

Ebenso ist es auch möglich, daß die Sensoreinrichtung eine Lichtquelle und einen Lichtsensor aufweist. Die Lichtquelle ist vorzugsweise so angeordnet, daß sie die Haut bestrahlt, wenn die Haarentfernungseinrichtung über die Haut bewegt wird. Dieses Ausführungsbeispiel der Sensoreinrichtung weist keine beweglichen Teile auf und besitzt daher eine lange Lebensdauer. Außerdem arbeitet eine derart ausgebildete Sensoreinrichtung sehr zuverlässig und präzise.Likewise, it is also possible that the sensor device has a light source and a light sensor. The light source is preferably arranged to irradiate the skin as the hair removal device is moved across the skin. This embodiment The sensor device has no moving parts and therefore has a long life. In addition, a sensor device designed in this way works very reliably and precisely.

In einem bevorzugten Ausführungsbeispiel weist das erfindungsgemäße Haarentfernungsgerät eine Steuereinrichtung zur Ansteuerung des Motors abhängig vom Signal der Sensoreinrichtung auf. Dabei kann vorgesehen sein, daß die Steuereinrichtung eine Bewegungsgröße einer Komponente der Haarentfernungseinrichtung auf einen ersten vorgebbaren Wert, der vom Signal der Sensoreinrichtung abhängt, regelt oder steuert. Dies bedeutet, daß die Bewegung dieser Komponente davon abhängt, wie schnell die Haarentfernungseinrichtung über die Haut bewegt wird. Bei der Bewegungsgröße kann es sich insbesondere um eine Geschwindigkeit oder eine Schwingungsamplitude der Komponente der Haarentfernungseinrichtung handeln.In a preferred embodiment, the hair removal device according to the invention has a control device for controlling the motor depending on the signal of the sensor device. It can be provided that the control device controls or controls a movement amount of a component of the hair removal device to a first predefinable value, which depends on the signal of the sensor device. This means that the movement of this component depends on how quickly the hair removal device is moved across the skin. The amount of movement may, in particular, be a speed or a vibration amplitude of the component of the hair removal device.

Ebenso ist es auch möglich, daß die Steuereinrichtung eine Bewegungsgröße des Motors auf einen zweiten vorgebbaren Wert, der vom Signal der Sensoreinrichtung abhängt, regelt oder steuert. Dabei ist es von Vorteil, wenn ein Motorsensor zur Bereitstellung eines Signals für die Steuereinrichtung vorgesehen ist, das von der Bewegungsgröße des Motors abhängt. Bei der Bewegungsgröße kann es sich um eine Drehzahl, eine Geschwindigkeit oder eine Schwingungsamplitude des Motors handeln. Besonders vorteilhaft ist es, wenn die Steuereinrichtung den zweiten vorgebbaren Wert auf Basis des ersten vorgebbaren Werts ermittelt.Likewise, it is also possible for the control device to regulate or control a movement variable of the motor to a second predefinable value, which depends on the signal of the sensor device. It is advantageous if a motor sensor is provided for providing a signal for the control device, which depends on the amount of movement of the motor. The amount of movement can be a speed, a speed or a vibration amplitude of the motor. It is particularly advantageous if the control device determines the second predefinable value on the basis of the first predefinable value.

Das erfindungsgemäße Haarentfernungsgerät kann so weitergebildet werden, daß die Steuereinrichtung den Motor abhängig von einer Benutzereinstellung für die Hautempfindlichkeit und/oder von einer Stromaufnahme des Motors und/oder von einem aktuellen Haarentfernungsmodus und/oder von einem in der Vergangenheit ermittelten Parameter und/oder von einem Fortschritt der Haarentfernung und/oder von einem Minimal- und/oder Maximalwert für die Bewegungsgröße des Motors oder der Komponente der Haarentfernungseinrichtung ansteuert. Dadurch kann das Haarentfernungsgerät noch weiter optimiert und speziell an den jeweiligen Benutzer angepaßt werden.The hair removal device according to the invention can be developed so that the control device, the motor depending on a user setting for skin sensitivity and / or a power consumption of the engine and / or a current hair removal mode and / or from a parameter determined in the past and / or a Advances the hair removal and / or of a minimum and / or maximum value for the amount of movement of the engine or the component of the hair removal device. As a result, the hair removal device can be further optimized and adapted to the particular user.

Beim erfindungsgemäßen Verfahren zum Entfernen von Haaren von der menschlichen Haut wird ein elektrisches Haarentfernungsgerät, das eine von einem Motor angetriebene Haarentfernungseinrichtung aufweist, über die Haut geführt. Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, daß der Motor abhängig von der Geschwindigkeit, mit der das Haarentfernungsgerät über die Haut bewegt wird, angesteuert wird.In the method of removing hair from human skin according to the present invention, there is provided an electric hair removal apparatus comprising a motor driven hair removal means has passed over the skin. The inventive method is characterized in that the motor is driven depending on the speed with which the hair removal device is moved over the skin.

Im Rahmen des erfindungsgemäßen Verfahrens kann eine Bewegungsgröße einer Komponente der Haarentfernungseinrichtung auf einen ersten vorgebbaren Wert geregelt oder gesteuert werden, der von der Geschwindigkeit abhängt, mit der das Haarentfernungsgerät über die Haut bewegt wird. Weiterhin kann eine Bewegungsgröße des Motors auf einen zweiten vorgebbaren Wert geregelt oder gesteuert werden, der von der Geschwindigkeit abhängt, mit der das Haarentfernungsgerät über die Haut bewegt wird.In the context of the method according to the invention, a movement amount of a component of the hair removal device can be regulated or controlled to a first predefinable value, which depends on the speed with which the hair removal device is moved over the skin. Furthermore, a movement amount of the motor can be controlled or controlled to a second predetermined value, which depends on the speed with which the hair removal device is moved over the skin.

Fig. 1 zeigt ein Ausführungsbeispiel eines erfindungsgemäß ausgebildeten elektrischen Rasierapparats 1 in Seitenansicht. Der Rasierapparat 1 weist ein in der Hand haltbares Gehäuse 2 und einen daran befestigten Scherkopf 3 auf. Am Gehäuse 2 ist ein Schalter 4 zum Ein-und Ausschalten des Rasierapparats 1 angeordnet. Fig. 1 shows an embodiment of an inventive electric shaver 1 in side view. The razor 1 has a housing 2 durable in the hand and a shaving head 3 attached thereto. On the housing 2, a switch 4 for switching on and off of the shaver 1 is arranged.

Der Scherkopf 3 weist ein Schersystem 5 mit einem Untermesser 6 und einer Scherfolie 7 auf. Die Scherfolie 7 ist in einem Halterahmen 8 angeordnet. Weiterhin weist der Scherkopf 3 eine Sensoreinrichtung 9 zur Erfassung der Geschwindigkeit auf, mit der der Scherkopf 3 während der Rasur über die Haut bewegt wird. Aufbau und Funktionsweise der Sensoreinrichtung 9 werden anhand der Fig. 2 und 3 näher erläutert.The shaving head 3 has a shearing system 5 with a lower blade 6 and a shearing foil 7. The shearing foil 7 is arranged in a holding frame 8. Furthermore, the shaving head 3 has a sensor device 9 for detecting the speed at which the shaving head 3 while the shave is moving over the skin. Structure and operation of the sensor device 9 are based on the FIGS. 2 and 3 explained in more detail.

Innerhalb des Gehäuses 2 sind weitere Komponenten angeordnet, von denen einige in Fig. 1 schematisch dargestellt sind. Eine dieser Komponenten ist ein Motor 10, der das Untermesser 6 antreibt. Der Motor 10 kann als Rotationsmotor ausgebildet sein und über einen nicht figürlich dargestellten Exzenter mit dem Untermesser 6 gekoppelt sein. Ebenso ist es auch möglich, den Motor 10 als Linearmotor auszubilden. Als weitere Komponenten sind eine wieder aufladbare Batterie 11 und ein Mikrocontroller 12 symbolisch dargestellt. Die Batterie 11 liefert die Versorgungsspannung zum Betrieb des Rasierapparats 1, wobei der Motor 10 der größte Energieverbraucher ist. Der Mikrocontroller 12 wird insbesondere für die im folgenden noch näher beschriebene Auswertung der Signale der Sensoreinrichtung 9 und Ansteuerung des Motors 10 benötigt.Within the housing 2 further components are arranged, some of which are in Fig. 1 are shown schematically. One of these components is a motor 10 that drives the lower blade 6. The motor 10 may be formed as a rotary motor and be coupled via a non-figured eccentric with the lower blade 6. Likewise, it is also possible to form the motor 10 as a linear motor. As further components, a rechargeable battery 11 and a microcontroller 12 are shown symbolically. The battery 11 provides the supply voltage for operation of the razor 1, wherein the motor 10 is the largest energy consumer. The microcontroller 12 is required in particular for the evaluation of the signals of the sensor device 9 and activation of the motor 10, which will be described in more detail below.

Beim Betrieb des Rasierapparats 1 wird das Untermesser 6 relativ zur Scherfolie 7 in eine linear oszillierende Bewegung versetzt. Diese Bewegung führt dazu, daß Haare, die durch die Scherfolie 7 bis zum Untermesser 6 vordringen, vom Untermesser 6 erfaßt und in Zusammenwirkung mit der Scherfolie 7 durchtrennt werden.During operation of the razor 1, the lower blade 6 is displaced relative to the shear foil 7 in a linear oscillating movement. This movement causes hair, which penetrate through the shear foil 7 to the lower blade 6, detected by the lower blade 6 and severed in cooperation with the shear foil 7.

Fig. 2 zeigt einen vergrößerten Ausschnitt des Rasierapparats 1 in Schnittdarstellung zur Veranschaulichung eines Ausführungsbeispiels der Sensoreinrichtung 9. Beim dargestellten Ausführungsbeispiel weist die Sensoreinrichtung 9 ein Geberrad 13 mit einer Achse 14 auf, die drehbar in einer Hülse 15 gelagert ist. Das Geberrad 13 weist mehrere Markierungen 16 auf, die in Umfangsrichtung des Geberrads 13 in regelmäßigen Abständen nebeneinander angeordnet sind. Im Bereich des Radius, in dem die Markierungen 16 auf dem Geberrad 13 angeordnet sind, ist neben dem Geberrad 13 ein Meßaufnehmer 17 angebracht. Der Meßaufnehmer 17 spricht auf die Markierungen 16 an und erzeugt bei einer Rotation des Geberrads 13 in dem Takt, in dem die Markierungen 16 am Meßaufnehmer 17 vorbei bewegt werden, ein Signal. Fig. 2 shows an enlarged detail of the razor 1 in sectional view to illustrate an embodiment of the sensor device 9. In the illustrated embodiment, the sensor device 9, a sensor wheel 13 with an axis 14 which is rotatably mounted in a sleeve 15. The sender wheel 13 has a plurality of markings 16, which are arranged in the circumferential direction of the sender wheel 13 at regular intervals next to each other. In the region of the radius in which the markings 16 are arranged on the encoder wheel 13, a measuring transducer 17 is mounted next to the encoder wheel 13. The transducer 17 is responsive to the markings 16 and generates at a rotation of the encoder wheel 13 in the clock in which the markers 16 are moved past the transducer 17, a signal.

Die Detektion der Markierungen 16 kann auf unterschiedliche Weise erfolgen, wie beispielsweise optisch, durch Induktion usw. Auch der mechanische Aufbau der Sensoreinrichtung 9 kann auf vielfältige Weise abgewandelt werden. So kann das Geberrad 13 von einem weiteren, nicht figürlich dargestellten Rad oder von einer Kugel angetrieben werden. Außerdem können mehrere unterschiedlich orientierte Geberräder 13 mit zugehörigen Meßaufnehmern 17 zur Erfassung unterschiedlicher Bewegungsrichtungen des Scherkopfes 3 vorgesehen sein.The detection of the markers 16 can be done in different ways, such as optically, by induction, etc. Also, the mechanical structure of the sensor device 9 can be modified in many ways. Thus, the encoder wheel 13 can be driven by another, non-figured wheel or by a ball. In addition, several differently oriented donor wheels 13 with associated measuring sensors 17 may be provided for detecting different directions of movement of the shaving head 3.

In Fig. 2 ist weiterhin eine Hautoberfläche 18 dargestellt, über die der Scherkopf 3 des Rasierapparats 1 bewegt wird, d. h. Fig. 2 zeigt eine Momentaufnahme während der Durchführung einer Rasur mit dem Rasierapparat 1. Während der Rasur wird der Scherkopf 3 mit leichtem Druck gegen die Hautoberfläche 18 gedrückt und dabei relativ zur Hautoberfläche 18 lateral bewegt. Außer der Scherfolie 7 liegt dabei auch das Geberrad 13 berührend an der Hautoberfläche 18 an und wandelt die Translationsbewegung des Scherkopfes 3 in eine Rotationsbewegung um, die vom Meßaufnehmer 17 erfaßt und ihn ein entsprechendes Signal umgesetzt wird. Bei einer schnellen Translationsbewegung des Scherkopfes 3 relativ zur Hautoberfläche 18 wird das Geberrad 13 in eine schnelle Rotationsbewegung versetzt, so daß der Meßaufnehmer 17 ein Signal mit einer relativ hohen Frequenz erzeugt und an seinem Ausgang bereitstellt. Bei einer langsamen Translationsbewegung des Scherkopfes 3 wird dagegen eine langsame Rotation des Geberrads 13 erzeugt, so daß das vom Meßaufnehmer 17 ausgegebene Signal eine relativ niedrige Frequenz aufweist. Die Frequenz des vom Meßaufnehmer 17 erzeugten Signals stellt somit ein Maß für die Geschwindigkeit dar, mit der der Scherkopf 3 des Rasierapparats 1 über die Hautoberfläche 18 bewegt wird. Diese Geschwindigkeit kann auch mit dem in Fig. 3 dargestellten Ausführungsbeispiel der Sensoreinrichtung 9 ermittelt werden.In Fig. 2 Furthermore, a skin surface 18 is shown, over which the shaving head 3 of the razor 1 is moved, ie Fig. 2 shows a snapshot during the implementation of a shave with the shaver 1. During shaving the shaving head 3 is pressed with light pressure against the skin surface 18 and thereby laterally relative to the skin surface 18 moves. In addition to the shaving foil 7, the transmitter wheel 13 also touches the skin surface 18 and converts the translational movement of the shaving head 3 into a rotational movement which is detected by the measuring transducer 17 and a corresponding signal is converted to it. In a rapid translational movement of the shaving head 3 relative to the skin surface 18, the encoder wheel 13 is set in a rapid rotational movement, so that the transducer 17 generates a signal at a relatively high frequency and provides at its output. With a slow translational movement of the shaving head 3, however, a slow rotation of the encoder wheel 13 is generated, so that the output signal from the transducer 17 has a relatively low frequency. The frequency of the signal generated by the transducer 17 thus represents a measure of the speed with which the shaving head 3 of the shaver 1 is moved over the skin surface 18. This speed can also be with the in Fig. 3 illustrated embodiment of the sensor device 9 can be determined.

Fig. 3 zeigt ein weiteres Ausführungsbeispiel der Sensoreinrichtung 9 in einer Fig. 2 entsprechenden Darstellung. Bei diesem Ausführungsbeispiel weist die Sensoreinrichtung 9 eine Lichtquelle 19 und einen Lichtsensor 20 auf. Bei der Lichtquelle 19 kann es sich beispielsweise um eine Leuchtdiode handeln. Als Lichtsensor 20 eignet sich insbesondere eine Photodiode. Die Lichtquelle 19 ist so im Scherkopf 3 angebracht, daß sie Licht in Richtung der Hautoberfläche 18 aussendet, wenn der Scherkopf 3 bei einer Rasur über die Hautoberfläche 18 bewegt wird. Das Licht wird zum Teil an der Hautoberfläche 18 reflektiert, wobei wiederum ein Teil des reflektierten Lichts vom Lichtsensor 20 erfaßt wird. Der Lichtsensor 20 erzeugt entsprechend dem erfaßten Licht ein elektrisches Signal, welches ein Maß für die Geschwindigkeit darstellt, mit der der Scherkopf 3 über die Hautoberfläche 18 bewegt wird. Die Auswertung des vom Lichtsensor 20 ausgegebenen Signals kann in ähnlicher Weise erfolgen wie bei einer optischen Computermaus. Fig. 3 shows a further embodiment of the sensor device 9 in one Fig. 2 corresponding representation. In this exemplary embodiment, the sensor device 9 has a light source 19 and a light sensor 20. The light source 19 may be, for example, a light emitting diode. As a light sensor 20 is particularly suitable a photodiode. The light source 19 is mounted in the shaving head 3 so that it emits light toward the skin surface 18 when the shaving head 3 is moved over the skin surface 18 during a shave. The light is reflected in part on the skin surface 18, again detecting a portion of the reflected light from the light sensor 20. The light sensor 20 generates an electrical signal corresponding to the detected light, which is a measure of the speed with which the shaving head 3 is moved over the skin surface 18. The evaluation of the output from the light sensor 20 signal can be carried out in a similar manner as in an optical computer mouse.

Die Weiterverarbeitung der mit den Ausführungsbeispielen gemäß Fig. 2 und Fig. 3 erzeugten Signale wird anhand von Fig. 4 näher erläutert.The further processing of the embodiments according to Fig. 2 and Fig. 3 generated signals is determined by Fig. 4 explained in more detail.

Fig. 4 zeigt eine Blockdarstellung für eine mögliche Variante einer erfindungsgemäßen Ansteuerung des Motors 10 des Rasierapparats 1. Die Darstellung bezieht sich auf ein Ausführungsbeispiel des Rasierapparats 1, bei dem der Motor 10 als Rotationsmotor ausgebildet ist. Die dargestellten Blöcke repräsentieren die Sensoreinrichtung 9, den Mikrocontroller 12, den Motor 10 und einen Drehzahlsensor 21, der die aktuelle Motordrehzahl erfaßt. Fig. 4 shows a block diagram of a possible variant of an inventive control of the motor 10 of the razor 1. The illustration refers to an embodiment of the razor 1, in which the motor 10 is designed as a rotary motor. The illustrated blocks represent the sensor device 9, the microcontroller 12, the engine 10 and a speed sensor 21 which detects the current engine speed.

Das von der Sensoreinrichtung 9 ausgegebene Signal wird dem Mikrocontroller 12 zugeführt. Der Mikrocontroller 12 ermittelt auf Basis dieses Signal einen Vorgabewert für die Geschwindigkeit des Untermessers 6 relativ zur Scherfolie 7. Der Vorgabewert kann beispielsweise mit Hilfe eines im Mikrocontroller 12 implementierten Algorithmus berechnet oder aus einer im Mikrocontroller 12 gespeicherten Tabelle ausgelesen werden. Dabei wird der Vorgabewert jeweils so gewählt, daß sich für die von der Sensoreinrichtung 9 ermittelte Geschwindigkeiten des Scherkopfes 3 relativ zur Hautoberfläche 18 günstige Schneidverhältnisse für das Durchtrennen der Haare ergeben. Beim Schneidvorgang werden die Haare jeweils unmittelbar vor dem Durchtrennen kurzzeitig zwischen dem Untermesser 6 und der Scherfolie 7 eingeklemmt. Durch die Bewegung des Scherkopfes 3 relativ zur Hautoberfläche 18 werden die eingeklemmten Haare geringfügig aus der Haut gezogen, bevor sie durch eine Zusammenwirkung des Untermessers und der Scherfolie durchtrennt werden. Dieser Effekt ist erwünscht und führt dazu, daß die Haare beim darauffolgenden zweiten Schnitt näher an ihrer Wurzel durchtrennt werden und dadurch eine sehr gründliche Rasur möglich ist.The signal output by the sensor device 9 is supplied to the microcontroller 12. Based on this signal, the microcontroller 12 determines a default value for the speed of the lower blade 6 relative to the shear foil 7. The default value can be calculated, for example, using an algorithm implemented in the microcontroller 12 or read out from a table stored in the microcontroller 12. In this case, the default value is selected in each case so that for the determined by the sensor device 9 speeds of the shaving head 3 relative to the skin surface 18 favorable cutting conditions for the severing of the hair. During the cutting process, the hairs are each clamped briefly between the lower blade 6 and the shaving foil 7 immediately before cutting. By the movement of the shaving head 3 relative to the skin surface 18, the pinched hairs are slightly pulled out of the skin before they are severed by an interaction of the lower blade and the shaving foil. This effect is desirable and causes the hair to be cut closer to its root in the subsequent second cut, thereby allowing a very thorough shave.

Allerdings dürfen die Haare nicht zu weit aus der Haut gezogen werden, da dies sonst für den Benutzer des Rasierapparats 1 schmerzhaft ist. Die Schmerzgrenze liegt typischerweise bei einem Wert von ca. 0,4 mm, d. h. wenn die Haare um mehr als 0,4 mm aus der Haut gezogen werden, wird dies üblicherweise als Schmerz empfunden. Umgekehrt wird die Rasur nicht besonders gründlich, wenn die Haare zu wenig aus der Haut gezogen werden. Dies bedeutet, daß die Haare nach dem Einklemmen relativ schnell durchtrennt werden sollten, wenn der Scherkopf 3 mit großer Geschwindigkeit über die Hautoberfläche 18 geführt wird. Wird der Scherkopf 3 dagegen langsam über die Hautoberfläche 18 geführt, so sollte eine größere Zeitspanne zwischen dem Einklemmen und Durchtrennen der Haare verstreichen. Dies kann im Rahmen der Erfindung dadurch erreicht werden, daß der Vorgabewert für die Geschwindigkeit des Untermessers 6 um so größer gewählt wird, je schneller der Scherkopf 3 über die Hautoberfläche 18 bewegt wird.However, the hair must not be pulled too far out of the skin, as this is otherwise painful for the user of the shaver 1. The pain threshold is typically around 0.4 mm, ie if the hair is pulled out of the skin by more than 0.4 mm, this is usually felt as pain. Conversely, shaving will not be particularly thorough if the hair is pulled out of the skin too little. This means that the hair should be severed relatively quickly after pinching, when the shaving head 3 is passed over the skin surface 18 at high speed. On the other hand, if the shaving head 3 is guided slowly over the skin surface 18, then a greater period of time should elapse between the pinching and severing of the hair. This can be achieved in the context of the invention in that the default value for the speed of the lower blade 6 is chosen to be greater, the faster the shaving head 3 is moved over the skin surface 18.

Aus dem Vorgabewert für die Geschwindigkeit des Untermessers 6 ermittelt der Mikrocontroller 12 einen Sollwert für die Drehzahl des Motors 10. Der Sollwert wird so gewählt, daß die Geschwindigkeit des Untermessers 6 mit dem Vorgabewert übereinstimmt, wenn sich der Motor 10 mit dem Sollwert für die Drehzahl dreht. Analog zum Vorgabewert für die Geschwindigkeit des Untermessers 6 kann auch der Sollwert für die Motordrehzahl mittels eines Algorithmus berechnet oder einer Tabelle entnommen werden. Der so ermittelte Sollwert der Motordrehzahl wird mit dem vom Drehzahlsensor 21 erfaßten Istwert verglichen. Auf Basis dieses Soll-Ist-Vergleichs steuert der Mikrocontroller 12 den Motor 10 so an, daß der Istwert sich dem Sollwert annähert. Dabei kann die Trägheit des Motors 10 berücksichtigt werden und der Motor 10 dementsprechend auf eine etwas höhere Drehzahl geregelt werden, als dies dem Sollwert entspricht.From the default value for the speed of the lower blade 6 of the microcontroller 12 determines a target value for the speed of the motor 10. The setpoint is chosen so that the speed of the lower blade 6 coincides with the default value when the engine 10 with the setpoint for the speed rotates. Analogous to the default value for the speed of the lower blade 6 and the target value for the engine speed can be calculated by means of an algorithm or taken from a table. The thus determined setpoint of the engine speed is compared with the actual value detected by the speed sensor 21. Based on this target-actual comparison of the microcontroller 12 controls the motor 10 so that the actual value approaches the target value. In this case, the inertia of the motor 10 can be taken into account and the motor 10 can be controlled accordingly to a slightly higher speed than corresponds to the desired value.

Bei der Ermittlung des Vorgabewerts für die Geschwindigkeit des Untermessers 6 können zusätzlich zum Signal der Sensoreinrichtung 9 ein oder mehrere Parameter berücksichtigt werden. Beispielsweise kann vorgesehen werden, daß der Benutzer am Rasierapparat 1 eine Einstellung bezüglich seiner Hautempfindlichkeit vornehmen kann. Diese Einstellung wird dann im Rahmen der Ermittlung des Vorgabewerts ausgewertet. Ebenso ist es möglich, die Stärke des Bartwuchses des Benutzers zu berücksichtigen. Die Stärke des Bartwuchses kann aus der Stromaufnahme des Motors 10 abgeschätzt werden. Zudem kann der jeweilige Rasiermodus Berücksichtung finden, in dem der Rasierapparat 1 betrieben wird. Beispielsweise kann bei ausgeklapptem Langhaarschneider ein konstanter Vorgabewert vorgesehen werden. Außerdem kann eine Speicherfunktion vorgesehen sein, mit deren Hilfe der Mikrocontroller 12 das Benutzerverhalten ermitteln und den Vorgabewert darauf abstimmen kann. Beispielsweise kann ein vergleichsweise hoher Vorgabewert gewählt werden, wenn sich der Benutzer üblicherweise schnell rasiert oder wenn der Rasierapparat 1 so lange nicht benutzt wurde, daß mit einer starken Ausprägung des Barts zu rechnen ist. Auch der Rasierfortschritt während einer Rasur kann bei der Ermittlung des Vorgabewerts berücksichtigt werden. So kann zu Beginn der Rasur ein anderer Vorgabewert gewählt werden als gegen Ende der Rasur. Zudem können bei der Ermittlung des Vorgabewerts ein Minimalwert und ein Maximalwert für die Geschwindigkeit des Untermessers 6 beachtet werden, die nicht unterschritten bzw. überschritten werden dürfen.When determining the default value for the speed of the lower blade 6, one or more parameters can be taken into account in addition to the signal of the sensor device 9. For example, it may be provided that the user on the shaver 1 can make an adjustment with respect to its skin sensitivity. This setting is then evaluated as part of the determination of the default value. It is also possible to consider the strength of the user's beard growth. The strength of the beard growth can be estimated from the current consumption of the motor 10. In addition, the particular shaving mode can be considered in which the shaver 1 is operated. For example, with a folded long-hair trimmer, a constant default value can be provided. In addition, a memory function may be provided with the aid of which the microcontroller 12 can determine the user behavior and tune the default value to it. For example, a comparatively high standard value can be selected if the user usually shaves quickly or if the razor 1 has not been used for so long that a strong expression of the barts is to be expected. Shaving progress during a shave can also be taken into account when determining the default value. Thus, at the beginning of the shave another default value can be selected as towards the end of the shave. In addition, when determining the default value, a minimum value and a maximum value for the speed of the lower blade 6 can be observed, which must not be exceeded or exceeded.

Weiterhin ist es auch möglich, bei der Ansteuerung des Motors 10 zu berücksichtigen, daß eine zu schnelle Regelung vom Benutzer als unangenehm empfunden wird und dementsprechend die Regelungsgeschwindigkeit zu begrenzen.Furthermore, it is also possible to take into account in the control of the motor 10 that too fast control is perceived by the user as unpleasant and accordingly to limit the control speed.

Bei einem Ausführungsbeispiel des Rasierapparats 1, bei dem der Motor 10 als ein Linearmotor ausgebildet ist, kann in entsprechender Weise, wie vorstehend für die Drehzahl eines Rotationsmotors beschrieben, die Motorgeschwindigkeit oder die Schwingungsamplitude des Motors 10 geregelt werden.In an embodiment of the razor 1 in which the motor 10 is designed as a linear motor, the motor speed or the vibration amplitude of the motor 10 can be controlled in a corresponding manner, as described above for the rotational speed of a rotary motor.

Weiterhin kann der Rasierapparat 1 jeweils auch so ausgeführt sein, daß unmittelbar eine Bewegungsgröße des Untermessers 6, beispielsweise dessen Geschwindigkeit oder Schwingungsamplitude, erfaßt und geregelt wird. Außerdem ist jeweils eine Abwandlung des Rasierapparats 1 möglich, bei der anstelle einer Regelung eine reine Steuerung ohne Istwerterfassung durchgeführt wird.Furthermore, the razor 1 can also be designed in each case so that directly a movement amount of the lower blade 6, for example, the speed or amplitude of vibration, is detected and regulated. In addition, a modification of the razor 1 is possible in each case, in which instead of a control, a pure control is performed without actual value detection.

Die Erfindung ist nicht auf eine Anwendung bei Rasierapparaten 1 begrenzt, sondern auch bei sonstigen elektrischen Haarentfernungsgeräten einsetzbar, die eine mechanisch arbeitende Haarentfernungseinrichtung aufweisen. Neben Rasierapparaten 1 können dies insbesondere Epilationsgeräte sein, die mit Hilfe von rotierenden Pinzetten Haare erfassen und aus der menschlichen Haut auszupfen. Bei Epilationsgeräten kann beispielsweise die Rotationsgeschwindigkeit der Pinzetten oder die Öffnungs- und/oder Schließgeschwindigkeit der Pinzetten abhängig von der Geschwindigkeit variiert werden, mit der das Epilationsgerät über die Haut bewegt wird.The invention is not limited to an application in razors 1, but can also be used in other electric hair removal devices having a mechanically working hair removal device. In addition to razors 1, these can be, in particular, epilation apparatuses which detect hairs with the aid of rotating tweezers and pluck them out of the human skin. In epilators, for example, the rotational speed of the forceps or the opening and / or closing speed of the forceps can be varied depending on the speed with which the epilation device is moved across the skin.
