    TECHNICAL FIELD The invention relates to a cleaning device for small parts, in particular of watches, with at least one cleaning basket which is suitable for receiving small parts, wherein the cleaning basket is arranged to rotate in a working chamber.
    PRIOR ART Various cleaning devices for small parts are already known, of which those which are used in connection with watches are generally also called watch-cleaning machines.
    For example, from the CH 340 455 A5 a watch cleaning machine is known. In this watch-cleaning machine several containers are arranged in a semicircle, which are suitable for receiving different cleaning and rinsing media. Each individual container plays a defined role in the cleaning process and is filled with media required for the cleaning process. As a container, for example, cylinder-like glasses are used, which are filled with the different cleaning and rinsing media and in the succession of the cleaning basket is immersed and there with a preferably rotating movement in each case a certain residence time remains. After several cleaning cycles, depending on the respective degree of cleaning, the glasses are then emptied by hand and filled with new cleaning and rinsing media and reused in the device.
    The containers are, as described above, cylinder-like glasses and open at the top. This brings the danger that, especially when using solvent-containing media, these vapors escape from these glasses and so on the one hand may be hazardous to health, for those who operates the device, but also the risk that due to a higher concentration quite possibly explosions ,
    From DE 762 840 A a device for cleaning of clock parts is known. The device described therein comprises a rotatable basket in which the parts to be cleaned are stored during the cleaning process. By rotating the basket in a cleaning liquid, which in turn is stored in a container, the desired cleaning is achieved. A coupled with a drive gearbox causes a self-running process of rotational movement of the basket and the raising and lowering of a lid, which is provided for the completion of the provided with the cleaning liquid container.
    DE 764 820 A discloses a watch-cleaning machine, which consists of for immersion in filled with cleaning and rinsing media vessels in which a basket for receiving watch parts is rotatably arranged. The basket is externally driven via a drive shaft, for example by an electric motor. It is additionally provided to arrange the vessels together with the drive shaft at an angle.
    From DE 741 303 A a cleaning machine for movements and clockwork small parts is also known. The parts to be cleaned are introduced into a basket, which in turn is coupled via a drive shaft with a drive. The drive is arranged on a cover element, which closes the respective vessels into which the basket is inserted and in which cleaning or rinsing liquid is provided. Several vessels are arranged side by side, so that the lid member can be transferred together with the drive and the basket coupled thereto optionally in one of the other vessels for the desired cleaning or rinsing.
    DE 1 771 256 A teaches a method and an apparatus for carrying out the method for cleaning fine mechanical small parts by successive cleaning and rinsing media in a cleaning vessel to which a vacuum is applied during the cleaning time. In this case, different types of liquids are supplied to the cleaning vessel by the application of the vacuum in dependence on the position of a manually operable control valve.
    From CH 272 001 a fully automatic machine for cleaning components of watches and fine mechanical small parts is known. This is characterized in that means for supplying a cleaning liquid from at least one storage container are provided in a serving for receiving the components container. In addition, means for conveying the cleaning liquid in said container, for sucking the cleaning liquid and for supplying rinse water into said container, for sucking the rinsing liquid and means for supplying drying air are known. The corresponding processes are program-controlled. Controlled under program control is understood to be an automatic or automatic passage through a previously defined and preferably programmed process.
    The previously known cleaning devices for small parts, especially those that are used for cleaning of clock parts and use solvent-containing vapors, have taken no precautions to avoid flammable gas mixtures can.
    An alternative to solvent-containing cleaning media is currently not given, since aqueous media on the one hand have a reduced cleaning power, but also cause corresponding corrosion, especially on the hardware.
    OBJECT OF THE INVENTION The object of the invention is to further develop a fully automatic machine for cleaning components of watches and for cleaning precision mechanical components in such a way that at least the operational reliability is improved. Solution to Problem The solution of the problem is provided by the features of claim 1.
    ADVANTAGES OF THE INVENTION A basic idea of the invention is that a fully automatic machine for cleaning small parts is to be designed in such a way that the cleaning and rinsing media, which are stored in separate containers, are automatically activated via a vacuum applied to the working chamber Process flow of the working chamber, in which the actual cleaning process is performed, are supplied. At the same time, the cleaning and rinsing media filled in the working chamber are also returned to the separate containers, without any mixing of the liquids occurring. This preserves the valency of the liquids.
    In one embodiment of the invention, the cleaning device is divided into two areas, namely in a first area which is provided for storing the cleaning and rinsing media. This storage area is arranged in the bottom area of the device and configured such that, in particular for the use of solvent-containing media, ventilation of this area takes place, so that explosive vapors, in particular their accumulation, are avoided. The further area of the cleaning device is designed as a working area, wherein within this working area the working chamber in which the actual cleaning process is carried out is arranged. Between the storage area and the working area of the cleaning device, an intermediate floor is arranged, which ensures a corresponding forced ventilation of the storage area.
    The storage of cleaning and rinsing media in containers is separated from the actual working chamber, so that even from this arrangement a threat to a possible explosion due to an accumulation of explosive vapors arising from the solvent-containing media is reduced or avoided. The appropriate ventilation in this storage area can be done on the one hand by an open construction of the cleaning device, so that a constant ventilation is given. On the other hand, it is also conceivable to arrange a corresponding forced ventilation. Forced ventilation is characterized by the fact that active fans prevent a certain dangerous concentration of vapors from accumulating spatially.
    The work area comprises as an essential feature a self-contained working chamber in which the small parts can be cleaned.
    The working chamber is a cylinder-like container, which is formed in the inner diameter larger than the cleaning basket, so that the property of the cleaning basket, rotating angeordnetzu be given. The working chamber is formed like a vessel and has an upper side. This top is characterized by an opening whose size is determined by the small parts in the cleaning basket. Furthermore, means are provided which set the cleaning basket in rotation. For this purpose, an axis is usually conceivable, which is coupled to the cleaning basket, wherein the axis of the cylinder-like container can be brought out. The end of this axis is provided with a drive, so that a corresponding rotation can take place. This drive is preferably electrical in nature.
    The working chamber has on one side, namely in the region of said opening, a re-sealable lid member. As a result, there is the possibility, among other things, that the working chamber can be completely closed to create and maintain a vacuum (vacuum) within the working chamber.
    One reason for creating and maintaining a vacuum is the lowering of an explosion probability within the working chamber. In addition, the prevailing oppression significantly reduces the explosive force.
    The corresponding drive means for the cleaning basket, but also the vacuum pump for generating the corresponding vacuum are also arranged in the work area.
    An embodiment provides to use a pump for the transport of cleaning and rinsing media from the containers to the working chamber.
    A further embodiment provides that instead of a pump for conveying the cleaning and flushing media in the working chamber, a negative pressure (vacuum) is generated, so that the corresponding cleaning and flushing media are supplied via a control valve. If the pressure is reduced, the stored liquid in turn flows into the corresponding container depending on the position of the control valve due to the force of gravity. It may provide an education that the cleaning and flushing media flow back into the same container from which they have been removed, so that these media are used several times. However, if the degree of contamination is too high, then these media can also run in a separate container and, if necessary, new media can be added again. Preferably, means are provided which determine the quality of the returning medium and then takes place on the basis of predetermined limit values, a return or a separation.
    The rotation of the cleaning basket within the working chamber serves for a better cleaning, but it may also be advantageous for dry operations (dry spinning).
    A particular embodiment provides that the working chamber is arranged inclined as seen from the vertical orientation. This has the advantage that - if at the lowest point of the inlet and outlet for the cleaning and rinsing media is present - the chamber is completely emptied each time. This ensures that cleaning and rinsing media can be used for a longer time, since they are only slightly or not mixed with each other.
    Finally, it is possible to provide at least one device in the form of a working chamber for cleaning the small parts in the work area, with which the small parts in the rotating cleaning basket can optionally also be subjected to an ultrasonic treatment or the same processes.
    Furthermore, rotations, such as spin processes for drying, but also additional Fleizungsvorgänge within the working chamber are conceivable that promote the drying process. For example, warm air can also be conducted into the working chamber via the control valve.
    Furthermore, the working chamber has an inlet and outlet opening. This is connected in a preferred embodiment with a single hose. This hose is led from this working chamber to a control valve. This control valve is a multi-way valve that is specially designed. This one multi-way valve, in turn, several hoses are supplied, the other end in the different containers, which serve to store the cleaning and rinsing media ends. A servomotor provides to turn the control valve in the respective desired or required by the process sequence of cleaning position, so that one of the corresponding cleaning and flushing media can be fed into the working chamber for the necessary cleaning and rinsing process. The supply preferably takes place by means provided in the working chamber suppression, which then leads to the fact that, depending on the position of the control valve, the liquid is automatically supplied from the containers.
    The control valve is arranged as an "intermediate element" between the storage and working area, but such that the drive for the control valve is arranged exclusively in the work area. This can be ensured that in the storage area no electrical switching elements are provided which could cause a corresponding triggering in an accumulation of explosive vapors.
    The control valve has a plurality of inputs. The inputs are intended for connection to the containers for storing the cleaning and rinsing media. In this case, preferably flexible hoses are provided, which produce a fluid-moderate connection between the control valve and the containers. This connection is airtight, such that in an indirect suction via the control valve, the transport of the liquid stored in the containers in the direction of the control valve is possible. In one embodiment, the control valve has only one outlet, which provides a fluid connection, which is also made airtight, between the control valve and the working chamber. Both the opening for the fluid connection to the working chamber and the openings for the fluid connection to the containers are stationary. This ensures that the respective hose connections at the openings can be monitored at least periodically. In addition, it is avoided that they can unintentionally solve due to possible movements.
    The control valve is now designed such that, depending on the position of an actuating element provided within the control element, a fluid communication is provided from the opening leading to one of the vessels and the opening at the control valve leading to the working chamber. In addition, it is provided that at least one position is formed such that there is no fluid connection between at least one of the containers and the working chamber. The adjusting element is preferably designed as a rotary element and rotatable about its central axis with a drive via the control of the fully automatic machine. The actuator is rotatable 360 degrees and thus has no directional binding.
    By the adjusting device or the servo motor, which is coupled for example via a toothed belt with the adjusting element, the opening of the actuating element with one of the openings, which are fluidly connected to the containers for the cleaning and rinsing media in combination, arranged overlapping so that a fluid-moderate connection between the one container and the working chamber is formed. Either due to a pump or due to the prevailing negative pressure in the working chamber, the liquid is sucked in the direction of the working chamber and into the working chamber. Once the working chamber is filled, the actuator is brought back into the position in which there is an interruption of the fluid connection between the container and the working chamber. The cleaning process within the working chamber can then take place. After completion of the cleaning process, the actuator moves back to the position in which already a fluid-moderate connection has taken place with the previous container. Due to the fact that now the present in the working chamber vacuum is given, the liquid flows back into the container by gravity again. The working chamber is now empty, and the actuator can move back to the locked position. In a further step, it is then possible, according to the processes as already described, to transfer liquid having other properties from the other containers for the specific purpose into the working chamber and to discharge it again from the working chamber into the corresponding container after the processing process ,
    A significant advantage of the device described herein and in particular the control valve is that the different liquids do not come into contact with each other, since no mixing container or other container for merging and collecting the liquid is provided. Technically designed is a direct path from the respective container via the control valve to the working chamber. Thus, the respective cleaning and rinsing media can be used much longer compared to the prior art, since mixing due to the technical design of the device is avoided.
    In addition, each container preferably on a ventilation, which is preferably also guided via a hose to the control valve. There, all incoming hoses are brought together within the control valve and out via a single hose from the storage area. This avoids accumulation of vapors within the storage area.
    Another essential for the safety of the application of the device contributing feature is that the preferably electric drive is arranged for the control valve outside the storage zone. As a result, the storage zone can be designed completely free of electrical switching operations.
    Furthermore, sensors are provided which allow a control and thus an automatic sequence of the cleaning process. On the front of the cleaner there is a control that interacts with the user. The user can then select either permanently set cleaning cycles or also cleaning and rinsing cycles or else individually adjustable processes. Furthermore, an indication of the status of the cleaning and rinsing processes provides information.
    Due to the particular two-part design of the cleaning device, in which preferably the lower area, the storage of cleaning and rinsing media is implemented, the storage area can be defined as a so-called zone 1. This zone 1 complies with the ATEX guidelines of the European Union. Zone 1 concerns explosion protection, ie the avoidance of effective ignition sources. Since no electrical switching elements are provided in this area, in the area in which occasionally can form a dangerous explosive atmosphere as a mixture of air and combustible gases, vapors or mist during normal operation, nevertheless no explosion can form.
    Further advantageous embodiments will become apparent from the following description, the drawings and the claims.

    DESCRIPTION OF AN EXEMPLARY EMBODIMENT In the following FIGS. 1 to 6 an embodiment of a cleaning device 1 is shown in an overall view and in a partial view. In particular, in FIGS. 1 and 2, an overview of the cleaning device 1 is first shown, whereas the other figures serve to describe and show the special features of this cleaning device 1.
    The cleaning device 1 according to FIGS. 1 and 2 consists of a housing G in two areas A, B. The area B serves for the storage of containers 2.2,2.3,2.4, which are suitable for receiving cleaning and rinsing media. This is preferably arranged in the bottom region of the cleaning device 1. This area is also designated as storage area B, The further area serves as work area A and essentially comprises a working chamber 1.2 and further technical means which are necessary for the operation of the cleaning of small parts within this working chamber 1.2. The areas A and B are arranged above one another via an intermediate floor 3, wherein the intermediate floor 3 has a cavity 4, which serves to ventilate this gap, so that it can be avoided that due to the use of solvent-containing cleaning and rinsing media explosive Accumulate vapors and possibly ignite.
    The storage area B for the storage of the corresponding container 2.2, 2.3, 2.4 is open on one side, so that here a corresponding circulation of the air is possible with this, the risk of accumulation of explosive gases at least reduced or avoided altogether becomes. The number of three containers represents only a selection of an embodiment. Of course, fewer, but also more containers may be provided, which are either fluidly connected to each other or at least indirectly with the working chamber.
    The storage area B has, as already described above, the different containers 2.2, 2.3, 2.4. The containers 2.2, 2.3, 2.4 themselves each have a resealable filler neck 2.5. Preferably, the containers are removable, so that a simple filling and outside the cleaning device 1 is possible. In addition, a sampling nozzle 2.6 is provided, via which the cleaning and rinsing liquid enters the working chamber 1.2 of the cleaning device 1. The sampling nozzle 2.6 has the property that it is provided with a quick coupling for receiving a corresponding element with a hose. Preferably, this is designed such that it is shut off without attached hose.
    For the fluidic connection at least indirectly to the working chamber, a hose 5.1 is preferably provided, one end of which is fixed in the respective container and the other end to a control valve 5. The control valve 5 will be described later in more detail. Furthermore, ventilation hoses 5.6 are provided which lead from the respective containers to the control valve 5. From there, the vent is collected via another hose element 5.7 out of the housing G. Preferably, an automatic shut-off valve 5.8 is arranged there.
    Depending on the number of corresponding containers, the number of tubes are provided, which are guided in the control valve 5. Centrally away from the control valve 5 leads a hose 5.2 in the working chamber 1.2. In the embodiment shown here, the working chamber is arranged obliquely 1.2, so that the hose 5.2 exits at the lowest point of the working chamber 1.2.
    The work area A further comprises devices which are suitable for automatically controlling the machining process. For this purpose, in particular a drive 1.4 is provided which indirectly drives a cleaning basket 1.6, which is arranged within the working chamber 1.2.
    Furthermore, a vacuum pump 1.7 is provided, which is coupled via hose lines 1.8 and a measuring instrument 1.9 with the working chamber 1.2, which is hermetically sealable with a cover element 1.10. If explosive gases are withdrawn via the vacuum, a ventilation hose 1.11 is provided, which carries the hazardous vapors to the outside via a device 1.12.
    Preferably, the working area A of the housing G is completely sheathed.
    An operating element 1.13 serves to observe the automatically running and previously programmed process within the working chamber 1.2, but also to trigger the corresponding commands for the cleaning process or the start of the different cleaning cycles. The cleaning device 1 is suitable for carrying out different processes. Thus, a variety of processes can be programmed, which can be very easily selected by the user depending on the application via the control panel.
    The control panel also serves to communicate error messages to the user so that they can be quickly corrected by the user.
    In Figs. 3 and 4, the control valve 5 is shown schematically in the formation of a multi-way valve. This control valve 5 consists of the actual multi-way valve 5.1 in the formation of a housing, a drive 5.5 and one within the multi-way valve 5.1. arranged adjusting element 5.10. The multi-way valve 5.1 is arranged in the region B, wherein the drive 5.5, as shown in Fig. 4, in the region A is arranged. Preferably, the drive 5.5 is mounted on the intermediate bottom 3.
    The multi-way valve 5.1 has the property that by different rotational positions of the actuating element 5.10 the different containers 2.2 and 2.3 and 2.4 (coupled via hoses 5.21 as shown in FIGS. 1 and 2) with an opening 5.3, in turn with the hose 5.2, which is guided in the working chamber 1.2, are fluidly connected. Furthermore, the multi-way valve 5.1 has further openings 5.11 which are fluid-moderately connected via hoses 5.21 with the respective containers in fluid communication.
    In this case, the different holes or positions are arranged such that, for example, the inlet into the working chamber 1.2 is completely closed at a valve position, so that within the working chamber 1.2, a corresponding vacuum can be formed.
    The adjusting element 5.10 is within the multi-way valve 5.1 rotatable in the direction of arrow 5.12 and in the opposite direction freely rotatable. One speaks of a 360-degree rotation. Inside, the actuator 5.10. a bore 5.13, which communicates with the opening 5.3 for fluidmässig connection to the working chamber 1.2. This bore is preferably located on the central axis, around which the actuator 5.10 is rotatable. In the bottom of the bore 5.13, a further bore 5.14 extends to the outer wall of the control element 5.10 and forms there another opening 5.15. This bore 5.14 or opening 5.15 can now communicate with the openings 5, 11, which are fluid-moderately connected via hoses 5.21 to the respective containers.

    The actuator 5.10 is thus by the drive 5.5 and the drive 5.5 coupled toothed belt 5.20 in and / or against the direction of rotation 5.12 set in motion, and that until a desired position corresponding to the respective machining process achieved becomes. Due to the drive, preferably a stepper motor, and the associated coupling element is an exact positioning of the adjusting element 5.10 possible. The opening 5.16 is a "blind opening". It is completed with a stuffing element (plug), so that when the actuator element 5.10 moves into this position, there is no fluid connection to the containers. This opening 5.16 could also be completely closed and would thereby achieve the same technical effect. The choice of Stopfelements can be seen in the fact that at any time, if needed, at this position a quick coupling for receiving a hose member can be attached so that liquid can be transported through this opening to the working chamber. Fig. 5 shows schematically the different positions and travel paths (1 to 12) of the control valve 5 during a cleaning process. The invention is not limited to the number of process routes. Rather, fewer or more process steps are possible, depending on which processes are to be performed. The corresponding numbering I-VI show the respective positions and the associated functions of the control valve 5 and is also only for explanation and as an example. Starting from the first position I, in which a vacuum is generated in the working chamber 1.2, the control valve 5 or the adjusting element 5.10 rotates in position II (travel path 1). In this position II is provided that the working chamber 1.2 is filled with detergent. The cleaning agent flows automatically into the working chamber 1.2, as there is a suppression in this. Subsequently (after the control valve (travel 2) has moved to position I), the actual processing, namely the cleaning takes place by the small parts are moved in the cleaning basket 1.6 within the cleaning liquid. Subsequently, in position II (travel 3) the cleaning liquid is drained off again. In a next step, the position VI is taken (travel 4). The rinsing liquid from the first container will now be the working chamber 1.2. fed. These process steps (travels 5-12) repeat themselves depending on the degree of soiling of the small parts to be cleaned and are shown schematically in FIG. Preferably, a further position IV with the position I is provided, in the position of which vacuum is produced in the working chamber 1.2, so that the rotational movements of the multiway valve 5.1 with respect to the individual travel paths are kept low (shown hatched). A fluid connection of the feeds to the control valve and the working chamber is not possible in these positions (I and IV). Fig. 6 shows to illustrate schematically the fluidic connection within the cleaning device 1. The different containers 2.2, 2.3, 2.4 are set via the control valve 5 with each other in fluid communication. The intermediate bottom 3 serves to separate the upper and lower areas. The fluid-moderate connection is performed by the actuator via a hose 5.2 in the working chamber 1.2. The working chamber 1.2 itself can be acted upon by a vacuum pump 1.7 with vacuum. Furthermore, corresponding return possibilities are present in the working chamber 1.2 if an overflow occurs with a cleaning or rinsing liquid. The inventive cleaning device is also characterized by the fact that it is essentially divided into two areas A and B, wherein the area B for storing cleaning and rinsing media, which in particular have solvent-containing properties, is suitable. As a result of this separation, it is possible that explosive vapors do not form in the area of the working chamber, so that the potential danger of an unwanted explosion is minimized or even completely avoided. The area A is characterized as a working area in which a working chamber is arranged, which is aufschlagbar with vacuum. Thus, advantageously pumps for the transport of the solvent-containing media are not needed. claims
