Definitions

  • the invention relates to a cleaning device with a receiving part for the shaving head of a shaving apparatus, as well as at least one cleaning liquid container and a conveyor device for the cleaning liquid which can be driven by a motor.
  • 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 fed continuously 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, the shaving head cannot be cleaned to the desired extent by means of an air stream.
  • 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 is seated for the entire cleaning period in a receiving part provided in the upper part of the housing, which is continuously up to is filled with cleaning liquid at the top and flows through it.
  • 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 thus into the shaving head area, so that this cleaning process likewise does not achieve satisfactory cleaning results, especially since after the conveyor device has been switched off, cleaning liquid with hair residues remains in the receiving part and therefore does not completely disappear the shaving head can be removed.
  • 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.
  • the chamber provided in the lower part of the housing for receiving the cleaning liquid and the dirt particles must remain closed during the circulation process of the cleaning liquid in such a way that the dirt particles which have already settled are not whirled up again. Nevertheless, it cannot be prevented that unfiltered cleaning liquid constantly gets to the shaving head during the circulation of the cleaning liquid.
  • the shaver can only be received in the receiving part of the cleaning device during the cleaning process. Then the shaver must be removed and is then placed separately on a drainer above the receiving part.
  • the object of the invention is to improve the cleaning device.
  • the receiving part for the shaving head is arranged separately from the cleaning liquid container and is supplied with cleaning liquid from the storage container for cleaning.
  • the cleaning liquid can be fed continuously by the feed pump to the shaving head accommodated in the separate receiving part until the shaving head has been completely cleaned.
  • the feed pump of the cleaning device can then be switched off and, after the cleaning liquid has been removed from the receiving part, the shaving head can be dried in the receiving part.
  • the receiving part is designed as a storage device for the shaving apparatus, to which an electrical device for starting up the shaving apparatus and the cleaning device or the shaving apparatus, the cleaning device and an air drying device is assigned.
  • the shaver does not need to be removed from the receiving part as before, but can also be dried in it and then stored.
  • the receiving part is designed as a cleaning tub, drying tub and / or storage device and / or provided in the cleaning device.
  • the receiving part or the shaving head for a certain period of time via the feed pump can be supplied with cleaning liquid from the cleaning liquid container, and that the receiving part is then available for the drying process without having to remove the shaving apparatus from the cleaning device.
  • the receiving part for receiving the shaving head is assigned an air drying device which is separate from the receiving part and which can be activated via an electrical device when the cleaning liquid is drained from the receiving part into the cleaning liquid container.
  • the receiving part is arranged outside the cleaning liquid and / or above the liquid level of the cleaning liquid provided in the cleaning liquid container and that at least the receiving part and / or the cleaning liquid container is constantly open to the outside or to the atmosphere.
  • the shaver can be inserted into and removed from the receiving part without any effort, without having to use any parts which close the receiving part.
  • a complex seal can be dispensed with, so that an inexpensive cleaning device can be built which is considerably more user-friendly than the previously known cleaning system.
  • the receiving part is equipped with an overflow device and / or with at least one outlet opening, through which cleaning liquid can be directed to a cleaning liquid container, and the cross section of the outlet opening in the receiving part is dimensioned such that less cleaning fluid flows through the outlet opening during the cleaning process than is supplied to the receiving part via the feed pump.
  • the overflow device which is part of the receiving part, ensures that the receiving part remains constantly filled with sufficient cleaning fluid, ie up to the upper edge region of the receiving part.
  • the cleaning is supported by the oscillating movement of the shaving head.
  • cavitation and also mechanical and / or fluid-related cleaning can take place at times in the cleaning process.
  • the oscillating movement of the shaving head causes cleaning fluid to splash up and penetrate all areas of the shaving head. Part of the churned-up liquid can flow off via the overflow device and be returned to the cleaning circuit without the liquid getting outside.
  • the feed pump is switched off for the further movement of the cleaning liquid, the cleaning liquid can flow off immediately via the outlet opening provided in the receiving part and the drying process for the shaving head can be used automatically.

  • the filter device consists of a connection piece onto which a hose part which allows the liquid to flow to the storage container is drawn up, which is immersed in the cleaning liquid provided in the cleaning liquid container.
  • the receiving part is always filled with cleaning liquid up to the upper edge through the overflow device. Excess cleaning liquid can then be easily passed via the overflow device into the collecting trough provided below the receiving part, which is connected to the corresponding nozzle.
  • the nozzle with the hose part protrudes continuously into the cleaning liquid provided in the cleaning liquid container.
  • the hose part ensures that no dirt collects in the cleaning liquid container and that at the beginning of the cleaning process the pump can draw liquid from the storage container through the hose part.
  • the nozzle is connected directly or indirectly to the inlet side of the feed pump, the outlet side of which is connected to a filter via a line. If the pump is switched on at the beginning of the cleaning process, it does not suck in air because the Hose is constantly immersed in the liquid. It is also advantageous that the filter is connected to the receiving part via an outlet connection and to the cleaning liquid container via an outlet opening provided in the receiving part.
  • the cleaning liquid drawn in via the feed pump from the cleaning liquid container reaches, as already mentioned, via the nozzle and the hose part to the inlet side of the feed pump and via the outlet line and possibly via a further line to the filter, which in turn is connected to the receiving part of the cleaning device . This closes the cleaning circuit for the cleaning liquid.

Due to the advantageous design of this holder, the shaving apparatus can be deposited in the cleaning device for an unlimited period of time in a faultless and well-protected manner and locked mechanically and electrically in the holder for the cleaning process, so that after the switching element is actuated, the shaving apparatus can no longer be removed, but only then when the cleaning and drying process is completed and the shaver is needed for shaving. This is made possible by the advantageous separation of the receiving part and the cleaning liquid container, since after the cleaning has ended, no cleaning liquid can remain in the receiving part.
  • the switching element for mechanical and / or electrical locking of the shaver against the actuating force a spring from an "off" position or unlockable position can be brought into at least one locking position of the shaver, which also corresponds to the "on" position for electrical activation of the shaver and that the "on" position for the electrical activation of the shaver also serves to activate the cleaning device.
  • the "on" position is used for the electrical activation of a charge control, in particular a charge control of a charging device in the shaving apparatus, and that the switching element can be connected to an electrical control circuit which switches on the cleaning device for a specific or programmable period of time and after cleaning the shaving head, the drying device of the shaver is switched on for a specific or programmable period of time.
  • the mechanical or electrical locking of the shaving apparatus is released by means of a corresponding timer, and this can be removed from the holder of the cleaning device if desired.
  • the shaver is to be used either as a mains or as a battery version, it can remain parked in the advantageously designed receiving part, since this remains dry after the cleaning process has been completed.
  • the cleaning device is designed for all electric shavers. Is z. B. a shaver for Battery operation included in the holder, so it can also remain there and be recharged if it should have discharged through prolonged non-use.
  • the advantageous design of the cleaning device in connection with a storage device results in a very compact device with which the shaver can be cleaned, dried, charged if necessary and, if desired, deposited, in a very short time.

  • the pawl 83 (FIG. 11) can be pivoted in the direction of the inner circumference of the fan wheel 16 between a position on the pawl axis 82 by means of the solid lines and a position shown in dashed lines by means of the spring 84 bent twice in a V-shape.
  • the spring 84 consists of a U-shaped part 110, via which the spring 84 is seated on a hub 97 of the driving flange 81.
  • the U-shaped part 110 is formed from two legs 111, each of which forms a double V with a further, adjoining leg 112.
  • the two pawls 83 lie with an outer end 85 each against the tooth flanks 86 of the ring gear 105 connected to the fan wheel 16 and in this way set clockwise a drive connection between the motor 28 and the fan wheel 16.
  • the legs 112 of the spring 84 press the lever arm 108 with its end 85 against the tooth flank 86 via an abutment.
  • the pawls 83 are first pressed outward via the tooth flanks 86 and, at a minimum speed due to their eccentric arrangement on the pawl axis 82, are pivoted outward in a clockwise direction on the pawl axis 82 against the action of the spring 84, until they come to rest against a stop 89 of the slot opening 88.
  • This is achieved in that the proportion by weight of the lever arm 108 is greater than the lever arm 109 of the pawl 83 that is different with respect to the pawl axis 82.
  • the fan wheel 16 is uncoupled from the motor output shaft 79. This position remains until the centrifugal torque is reduced by reducing the speed so that the spring force predominates and the pawls 83 return to the latching position according to FIG. 11 (see the position of the pawl 83 shown in solid lines).
  • the two lower pawls 90 only leave their detent position again, thereby releasing the drive connection between the motor 18 and the feed pump 23 when the direction of rotation of the motor 28 is changed. Since the outer ends of the pawls 83, 90 do not slip over the tooth flanks 86, no drive noises and no wear occur when the pawls 83, 90 are freewheeling.
  • a second drive motor for the separate drive of feed pump 23 and fan wheel 16 can be dispensed with, so that costs can be saved.
  • the motor 28 and the fan wheel 16, as well as the pump 23 (not shown in FIGS. 5, 10 and 11) and possibly the cleaning liquid container 61 can be arranged coaxially with one another, so that the gear parts between the motor 28, pump 23 and fan wheel 16 are reduced to a minimum can be and thus the housing 4 of the cleaning device 5 can be made smaller (see Fig. 12).
  • FIG. 1 Another embodiment of a drive device for the pump 23 and the drying device with the fan wheel 16 is shown in FIG.
  • a freewheel 78 similar to the freewheel device according to FIG. 11, consists here of only two pawls 83 or others Coupling elements.
  • the coupling elements establish a drive connection between the motor 13 and pump 23 or prevent the pump 23 from rotating when the direction of rotation of the motor 13 is reversed.
  • a differently designed freewheel device can also be used.
  • the fan wheel 16 cannot suck any air out of the receiving part 7, since a lamella closure 149 in the opening 18 remains closed by the negative pressure generated by the fan wheel 16.
  • the electric motor 13 drives the fan wheel 16 constantly in both directions due to the very simple design of the freewheel device, so that when the motor 13 is driven clockwise the air flow of the fan wheel 16 opens the lamella closure 149 provided in the opening 18 and the shaving head 3 air for the drying process feeds.
