Definitions

  • the invention relates to a method for cleaning a shaving head of a dry shaving apparatus, cleaning fluid being conveyed through the shaving head of the dry shaving apparatus during a first phase of a cleaning process by means of conveying means.
  • a cleaning device for the shaving head of a dry shaver which consists of a cleaning housing in which a receiving part for the shaving head of a shaving apparatus is provided in the upper region.
  • the individual components of the shaving head are cleaned by an air stream which is continuously fed to the shaving head via a propeller fan and filter elements.
  • the shaving head is very dirty and has, for example, sebum or grease residues, cleaning of the shaving head by means of an air stream cannot be achieved to the desired extent.
  • the entire housing of the cleaning device, which is flushed with air, must be well sealed from the atmosphere so that the swirled hair dust cannot escape to the outside.
  • the cleaning device according to another exemplary embodiment (US Pat. No. 3,172,416), according to which the shaving head is cleaned using a cleaning liquid which is passed for this purpose via flow channels provided in the housing.
  • the shaving head sits for the entire cleaning period in a receiving part provided in the upper part of the housing, which is constantly filled with cleaning liquid up to the top, and through which it flows.
  • a feed pump is provided in the housing. Since the cleaning liquid is not filtered during the cleaning process, hair residues repeatedly get to the receiving part and thereby into the shaving head area, so that none of these also result from this cleaning process satisfactory cleaning results are achieved, especially since after the conveying device has been switched off, cleaning fluid with hair residues remains in the receiving part and cannot therefore be completely removed from the shaving head.
  • the shaver When the cleaning process is finished, the shaver must be removed from the receiving part so that the shaving head can drip off and only then can it air dry. The hair residues conveyed by the cleaning liquid remain adhering to the components of the shaving head, so that ultimately no complete cleaning of the shaving head is achieved.
  • a device for cleaning a shaving head of a dry shaving apparatus in which the shaving head is inserted through a wall designed as a membrane into a cleaning room and then held in a cleaning position by a cover wall.
  • a blower and / or suction device By means of air flowed through a blower and / or suction device, only loose hair dust located in the shaving head, but not firmly adhering hair dust, is blown out or extracted and then transported to a filter device.
  • the cleaning measures additionally proposed in combination with the suction device are not suitable for removing existing skin sebum with or without hair dust from all components of a shaving head - inside of the shaving head frame, upper knife, lower knife - not even with one previous removal of the shaving head from the housing of a dry shaving apparatus or disassembly of the shaving head.
  • the object of the invention is to provide a method for cleaning the shaving head Specify dry shaving apparatus, by means of which a thorough cleaning of the shaving head can be carried out with the aid of a cleaning liquid.
  • the embodiment of the method according to claim 1 advantageously shows that the dry shaving apparatus is dried at the end of the cleaning process, so that the dry shaving apparatus is immediately ready for a new shave after the cleaning process has ended.
  • the embodiment of the method according to claim 3 basically ensures the commissioning of a dry shaving apparatus for faster and at the same time thorough cleaning of the shaving head, in particular of its cutting elements.
  • the method according to claim 4 advantageously shows that deep discharge of the batteries of the dry shaving apparatus can be avoided.
  • the intensity of the cleaning process (and thus also the duration of the cleaning process and / or the consumption of cleaning fluid) can be adapted to the contamination of the shaving apparatus.
  • the embodiment of the method according to claim 6 represents a particularly simple way of adjusting the intensity of the cleaning process.
  • the embodiment of the method according to claim 7 shows simple options for changing the intensity of the cleaning process.
  • a particularly good drying of the dry shaving apparatus can be achieved by shaking the cleaning liquid from the shaving head for a certain period of time.
  • Claim 10 indicates a simple, feasible method of operation of the drying device.
  • the configuration of the method according to claim 11 can prevent the user from interrupting the cleaning process in order to shave. It is then ensured that the user can only shave again when the cleaning process has been completed and thus the dry shaving apparatus has dried again at the end of the cleaning process.

  • the actuator 124 also serves as a locking device.
  • the end of the lever arm 125 establishes a current connection between the contact pins 12 of the dry shaver 1 and the electrical switching device 29, so that when the switching element 9 is actuated downwards, the circuit between the dry shaver 1 and the power supply device is established.
  • the first lever arm 119 is operatively connected to the unlocking device via an adjusting pin 118 and a spring 121.
  • the unlocking device has an actuating pin 118 which is acted upon by the amplifier 117, which for this purpose is connected to the switching device 29 via an electrical line 139. If the drying process according to FIG. 4 is completed at point 34, the actuator 124 and thus the unlocking device are acted on via the amplifier 117. The actuator 124 interrupts the power supply to the dry shaver 1 and at the same time also causes the mechanical unlocking, so that the dry shaver 1 can be removed from the receiving part 7 if desired.
  • the cleaning and drying process of the shaver is as follows.
  • the dry shaving apparatus 1 is inserted into the receiving part 7 according to FIG. 1 with the shaving head attached, and the cleaning device can now be connected to the power supply if it is not yet connected to the power supply.
  • the cleaning process is initiated by adjusting the switching element 9, so that the dry shaving apparatus 1 is then mechanically locked via the actuating part 124.
  • the mechanical locking also causes the electrical locking at the same time, thereby producing a power supply via the contact pins 12, the position 124 and the line 116 to the dry shaving apparatus 1. Now can start the charging process for the shaver 1. After the minimum loading capacity is reached, the shaving head 3 is set in vibration.
  • the feed pump 23 is switched on via the amplifier 113, cleaning liquid is fed to the receiving part 7 and thus also to the oscillating shaving head 3.
  • the receiving part 7 is automatically emptied according to route b, so that according to distance c, the shaving head 3 can be freed of residual liquid by further oscillating movements.
  • the drying device or the fan 16 is connected via the amplifier 115 and is connected via the electrical line 126 to a heater 127, shown schematically. Experience has shown that the drying process that now begins takes between 10 and 30 minutes and is shown in FIG. 4 by distance d.
  • the end of the drying process is reached and the fan 16 is switched off again via the amplifier 115.
  • the adjustment of the adjusting part 124 and thereby the mechanical unlocking of the dry shaving apparatus 1 is also carried out via the amplifier 117 and the actuating pin 118.
  • the mechanical unlocking likewise interrupts the power supply to the shaving apparatus in the line 116.
  • the adjusting member 124 By pivoting the adjusting member 124 in the counterclockwise direction, the shaver 1 can only be removed when the entire cleaning and drying process has been completed. If this process and these individual method steps have not been carried out in the manner described, the adjusting element 124 cannot be adjusted either and the premature removal of the shaving apparatus 1 is prevented.
  • the entire electrical switching device 29 with the individual amplifiers can accommodate themselves in the smallest space within the housing 4 of the cleaning device and thus protect them from moisture without further notice.
  • the operating display 135 with the switch 136 informs the operator that the cleaning process has not yet been completed, while the display device 138 indicates that the cleaning process has been completed.
