Definitions
- the invention relates to a cleaning device for a shaving head of a dry shaving apparatus with a receiving part, into which the shaving head can be inserted and to which a cleaning liquid can be applied, with a container for storing the cleaning liquid, from which the cleaning liquid is conveyed into the receiving part, from which the cleaning liquid flows back into the container via a return line.
- Such a cleaning device is known from DE 44 02 238 A1.
- the dry shaving apparatus is inserted with its shaving head into the receiving part.
- the receiving part is adapted with its trough-shaped design to the contour of the shaving head and takes it completely in itself.
- the receiving part has an outlet opening and an overflow, which open into a collecting container.
- the collecting container is connected to the container for the cleaning liquid via a return line.
- the container has a first opening, into which the return line is inserted in a sealing manner.
- the cleaning liquid is conveyed from the container through the motor-driven conveyor through a second opening into the receiving part by means of a line.
- the receiving part is continuously flushed with cleaning liquid. This means that exactly the amount of cleaning liquid that is conveyed into the receiving part flows back into the container via the return line.
- cleaning liquid is conveyed from the container into the receiving part. Until the receiving part is filled to the overflow, little or no cleaning fluid flows back into the container. This causes the level in the container to drop. This reduction in the fill level causes an increase in the air volume in the container, as a result of which the pressure in the container drops. This pressure, which is lower than the atmospheric pressure, causes the inflow of air via the return line which connects the receiving part to the container. Since at the beginning of the cleaning process the cleaning liquid has not yet completely filled the receiving part and during the first time of the backflow into the container, the cross section of the return line is not completely closed by the backflowing cleaning liquid, the pressure difference between the container and the surrounding atmosphere is caused by the over air flowing into the return line is balanced.
- the container is aerated. After the receiving part is filled, the amount of cleaning liquid which is supplied to the receiving part flows out into the container via the return line. This leads at the latest after switching off the conveyor der adopted for an increase in the level in the container and a corresponding reduction in the air volume, whereby the pressure in the container increases. Due to the now lower ambient pressure, the air present in the container tends to escape from the container. The cleaning fluid flowing back, however, results in a liquid seal in the return line, as a result of which the air in the container is prevented from escaping. Only when the pressure in the container is sufficiently high can the air overcome the resistance of the cleaning liquid flowing back and escape from the container. The container is therefore deflated late.
- the resulting disadvantages are that the backflow of the cleaning liquid is hindered by the escaping air. These brief interruptions in the backflow of the cleaning liquid lead to short liquid jams in the receiving part, as a result of which the flow which forms in the receiving part is disturbed. This flow is important for the removal of the hair pieces released from the shaving head. If this flow is disturbed, the removal of the hair remnants from the receiving part is ultimately hindered. In individual cases, the sudden venting of the container is associated with noise, which the user of the cleaning device could find annoying.
- the present invention is therefore based on the object of providing a cleaning device of the type mentioned at the outset which enables the cleaning liquid to flow back undisturbed into the container. Furthermore, the flow for removal, the hair residues accumulating in the receiving part should not be disturbed.
- a venting device is provided for the container. Via this separate ventilation device, the air in the container can escape through its own outlet if the internal pressure is too high, without being disturbed by another medium.
- the advantage of such a cleaning device is that the cleaning liquid is no longer hindered by air escaping from the container when it flows back from the receiving part via the line into the container and can therefore flow continuously into the container. At the same time, the short liquid jams in the receiving part are avoided, which are responsible for the disturbance of the flow forming in the exceptional part.
- the cleaning device according to the invention therefore ensures safe removal of the hair residues from the receiving part into the container.
- the venting device also enables a smoother venting of the container. This prevents the air from escaping quickly and suddenly, so that venting always takes place without making any noise.
- the vent device can also serve as a ventilation device by appropriate design.
- the ventilation device consists of a ventilation pipe.
- the ventilation pipe can be connected to the return line to form a common component.
- the ventilation pipe forms, together with the return line, a component divided into two flow areas by a partition.
- the cross sections of both flow channels can be the same.
- the flow channel forming the return line has a larger cross section than the flow channel forming the ventilation pipe.
- the cross-sectional shapes of the individual lines can be arbitrary, e.g. semicircular, rectangular, oval.
- the container can have an opening through which the ventilation device is guided in a sealed manner by a seal.
- the lower end of the vent pipe must be located above the maximum fill level in the container and extend outside the container.
- the arrangement above the maximum fill level guarantees reliable ventilation at all times.
- Such a ventilation device is very simple and is therefore characterized by low costs and simple assembly.
- the ventilation pipe ends immediately above the upper container wall If the cleaning device is in an inclined position, this can lead to cleaning liquid escaping through the ventilation pipe.
- the upper end of the ventilation pipe is extended above the container, the extension being able to extend to the level of the receiving part. An extension of the vent pipe reliably prevents the unwanted escaping of cleaning fluid even in the case of an inclined position of the cleaning device.
- the venting device can be integrated into the container for the cleaning liquid.
- the Containers By renewing the cleaning liquid at certain intervals, the Containers as a replacement part are required in much larger quantities than the entire cleaning device.
- the ventilation device With the integration of the ventilation device on the container, a very large number of ventilation devices is necessary. It is therefore advantageous if the ventilation device is fixedly arranged on the cleaning device.
- the ventilation device is fastened to a chassis plate carrying the chassis of the cleaning device, in particular locked by means of hooks.
- the venting device can be connected to the chassis plate in a replaceable manner or in one piece.
- corresponding locking points are arranged on the ventilation device and the chassis plate. This can be a collar which runs radially around the ventilation device and which, e.g. the hook work together.
- the vent pipe is connected in an advantageous embodiment to the return line and is inserted with it in a common opening in the container. This has the advantage that only one opening has to be sealed against leakage of the cleaning liquid.
- the connection of the vent pipe to the return line is possible in a wide variety of ways.
- the vent pipe and the return line can be connected by a positive connection by means of a snap or clip connection, or a material connection. It is also conceivable to connect the two tubes by means of webs.
- the two lines form a common component, which has a dividing wall for subdivision into two flow channels.
- At least a portion of the wall of the ventilation device extends to the bottom of the container.
- a partial area of the wall of the venting device or a partial area of the return line can be designed in such a way that a flow favoring the sedimentation of dirt particles forms in the cleaning liquid flowing back from the return line.
- a portion of the wall of the venting device can be designed such that the cleaning liquid can be deflected at an angle, preferably approximately parallel to the bottom of the container, when it emerges from the return line. With a cleaning liquid that hits the bottom of the container vertically, turbulence can arise that whirl up dirt particles already deposited on the bottom.
- the cleaning liquid flows parallel or at a slight angle to the bottom of the container. In the process, a flow is formed which favors the deposition of those hair residues which have been removed from the receiving part by the cleaning liquid.
- the wall section deflecting the cleaning liquid can also be part of the wall of the return line. In order to generate as large a deposit of dirt particles as possible and thus to keep the number of particles in the circulating cleaning liquid low, deflecting the inflowing cleaning liquid in a direction away from the suction line has proven to be advantageous.
- the cleaning device according to the invention is particularly cost-effective if the ventilation device is a ventilation hole with a small cross-section, preferably with a diameter of approximately 1 mm to 2 mm, in particular 1.5 mm.
- a vent hole can be arranged, for example, in the seal for the opening through which the return line enters the container or in the container wall. Leakage of cleaning fluid is reliably avoided if the diameter of the bore is selected such that air can escape, while the cleaning fluid is no longer able to do so due to its surface tension.
- the vent hole can also be covered by an air-permeable and liquid-tight membrane.
- the ventilation device can be designed as a valve.
- Valves with a membrane as the closing element have proven to be particularly favorable, since a very low opening pressure of the valve can be set with a membrane.
- the membrane also has the advantage that it closes the opening when the shaving head is not being cleaned. This prevents the cleaning liquid, which contains volatile components, from evaporating.
- FIG. 1 a cleaning device
- FIG. 2 a section through a receiving part and a ventilation device
- FIG. 3 shows a perspective view of the receiving part with the ventilation device according to FIG.
- Figure 4 a second embodiment of a ventilation device.
- the cleaning device 1 shown in Figure 1 consists of a base plate 2 and a chassis 3.
- the chassis 3 is composed of two housing parts 4, 5. Through an opening 6 in the housing part 4, a dry shaver (not shown) with its shaving head is inserted into a receiving part 7 for cleaning. Under the chassis 3 are the facilities necessary for cleaning the dry shaver, e.g. the container and the conveyor for the cleaning liquid are arranged.
- the receiving part 7 shown in Figure 2 is arranged above a chassis plate 8 supporting the chassis 3.
- a venting device 10 is inserted in an opening 9 of the chassis plate 8.
- the ventilation device 10 has a collar 11 with which the ventilation device 10 is seated on the opening 9.
- the venting device 10 is fastened to the chassis plate 8 via the collar 11 by means of hooks 12 arranged on the chassis plate 8.
- the venting device 10 is inserted into an opening 13 of a container 14 which contains the cleaning liquid 15.
- a lip seal 16 seals the ventilation device 10 against the opening 13.
- the receiving part 7 has an opening 17 in the lower region, into which the ventilation device 10 is inserted.
- An O-ring 18 seals this connection.
- the venting device 10 comprises a venting pipe 19 which extends above the maximum fill level in the container 14 up to the level of the receiving part 7.
- the arrangement of the vent pipe 19 above the maximum fill level ensures adequate venting of the container 14 at all times.
- the escaping air is shown with arrows. Because of the length of the ventilation pipe 19, no cleaning liquid 15 can escape through the ventilation pipe 19 even when the cleaning device 1 is inclined considerably.
- the vent pipe 19 forms a common component with a common partition 21 with a return line 20.
- the cleaning liquid 15 conveyed into the receiving part 7 for cleaning the shaving head can flow back into the container 14 via the return line 10.
- a portion of the wall 22 of the ventilation device 10 is extended downwards.
- FIG. 3 shows the arrangement of the receiving part 7 above the chassis plate 8.
- the receiving part 7 is inserted into the ventilation device 10.
- the ventilation device 10 is fastened to the chassis plate 8 via the collar 11 with the hooks 12.
- the ventilation device 10 is sealed off from the container (not shown in this figure) via the lip seal 16.
- the vent pipe 19 is arranged on the side next to the receiving part 7.
- the ventilation device 10 is a ventilation hole 23.
- the ventilation hole 23 has a diameter of 1.5 mm and is arranged in the seal 16, with which the return line 20 is sealed against the opening 13 of the container 14.
- a portion 24 of the wall of the return line 20 is angled at the lower end. As a result, the cleaning fluid 15 flowing back is deflected laterally, which favors the deposition of the hair residues 25.
