Description

Device for cleaning and / or disinfecting a dispensing head

The invention relates to a device for cleaning and / or disinfecting a tap head, which has a collar-like lower section with segment-like projections, the lower section being provided on its circumference with a cylindrical outer circumferential surface and on the inside with a recess which is provided by an axially recessed radial Attachment surface, a cylindrical inner circumferential surface, a lower radial surface, and a segment circumferential surface is formed, and with an adapter on which the tap head can be placed, the adapter containing first means for applying a cleaning liquid to a surface of the recess. Devices of the type mentioned above are known, for example from DE 198 49 153 AI.

For dispensing systems for beverages, in particular carbonated beverages, it is necessary for hygienic reasons to clean the dispensing system at regular intervals. Such cleaning includes not only the cleaning of the tap, which is usually located in the area of a counter of a restaurant, as well as the cleaning of the beverage cellar leading to the beverage cellar. Rather, it is also necessary to clean the tap head on those surfaces that can come into contact with the beverage.

Dispensing heads are of a standardized design on their underside so that when a new drum is struck, it can be placed on a complementary, also standardized, fitting of the beverage drum or removed again when the drum is knocked off. The actual contact surface of the tap head is a radial attachment surface that is placed on a corresponding counter surface of the barrel fitting, so that the beverage line is connected to the riser pipe of the beverage barrel.

To fix the barrel head on the barrel fitting, a bayonet-like arrangement is used, which is formed from a cylindrical inner circumferential surface, a lower radial surface and segment-circumferential surfaces projecting inward over the circumference. The segments are inserted from above when a barrel is struck into corresponding recesses in the barrel fitting. The tap head is then rotated about a common axis of the tap head and barrel fitting so that the segments are then under speaking opposite segments of the barrel fitting get and wedged there.

The striking process is then effected by pivoting a lever on the dispensing head. This establishes the connection between a riser of the beverage barrel and the beverage line leading to a bar counter. Furthermore, by pivoting the lever, the gas line is opened so that the conveying gas (C0 ₂ ) can get into the beverage barrel.

For a contact with the beverage when hitting and knocking off a barrel, the radial top surface of the tap head is primarily considered.

In conventional devices of the type mentioned, the tap head is placed on the spatially fixed adapter that is designed principally as a keg fitting, but instead of a riser pipe includes a pipe which can be supplied with a cleaning liquid. Because in conventional cleaning adapters such as this, the tap head is simulated, the gas line for the conveying gas must be shut off before the tap head is connected to the cleaning adapter, because otherwise the conveying gas would escape in an uncontrolled manner.

In this context, it should be pointed out that in the context of the present application “cleaning” is understood to mean all processes which can be initiated in connection with a cleaning process, that is to say also disinfection, rinsing and the like. Conventional devices of the type mentioned at the outset are designed in such a way that only the radial attachment surface is cleaned when cleaning on the adapter, because — as mentioned — only the process of striking is imitated when the dispensing head is placed on the cleaning adapter. With such conventional cleaning adapters it is therefore only possible to clean surfaces or cavities which are accessible even when the dispensing head is in the struck state. However, those areas that cannot be reached by shutting off the gas line, in contrast to the struck state, are not accessible.

In practice, however, this form of cleaning has not always been sufficient under certain operating conditions. When a barrel is struck and knocked off, traces of the beverage can reach the other surfaces of the tap head, which serve to connect the tap head to the barrel fitting, i.e. the cylindrical inner circumferential surface, the lower radial surface and the segment circumferential surface. These latter surfaces are not cleaned by conventional devices.

On the other hand, even relatively small traces, i.e. drops of drink, for example beer, that settle on these surfaces can lead to hygienic problems, in particular if the barrel is in a relatively warm environment, for example during the warm season. The invention is based on the object of developing a device of the type mentioned at the outset such that these disadvantages are avoided. In particular, a device is to be made available in which all surfaces of the dispensing head that are suitable for contact with the beverage are effectively cleaned.

This object is achieved according to the invention in that the adapter has an annular sealing insert into which the tap head with the cylindrical outer circumferential surface can initially be inserted loosely in a first operating position and can then be locked liquid-tight in a second operating position, in such a way that a cavity is formed which is at least is limited by the radial top surface, the cylindrical inner peripheral surface, the lower radial surface, the segment peripheral surface, and a surface of the adapter, and that the first means are connected to the cavity.

The object underlying the invention is completely achieved in this way.

The fact that all the surfaces of the dispensing head that are suitable for contact with the beverage form surface sections of a liquid-tightly closed cavity enables simple cleaning of all of the aforementioned surfaces by introducing a cleaning liquid into this cavity. In contrast to known devices, there are therefore no areas of the dispensing head which are still provided with beverage residues and can therefore represent a hygienic problem. This is essentially due to the fact that no striking is simulated in the device according to the invention. The tap head is namely not placed on the cleaning adapter by pivoting the lever and fastened there. Rather, this is done only by axial placement and twisting. In contrast to conventional cleaning adapters, the gas line for the conveying gas does not have to be shut off.

In a preferred embodiment of the device according to the invention the pin head in a known manner is lockably insertable into the adapter in the direction of a common axis in the first operating position and by turning the keg coupler relative to the adapter about the axis with the adapter in the second operating position.

This measure has the advantage that the user can establish a connection between the dispensing head and the adapter with the handles that are familiar to him.

In this case, it is further preferred if second means are provided in order to press the sealing insert radially inward against the cylindrical outer circumferential surface during the relative rotation of the tap head and the adapter.

This measure has the advantage that the necessary tightness of the cavity can be achieved directly by the usual twisting of the tap head relative to the adapter.

In a particularly preferred implementation of the exemplary embodiment mentioned above, the adapter has an inner part which is essentially spatially fixed when used as intended and a housing part movable relative to the inner part and encompassing the sealing insert with a coaxial inner circumferential surface, the inner part axially fixing the sealing insert, the inner circumferential surface of the housing part also tapering, and finally the second means moving the housing part relative to the inner part in the direction the axis.

This measure has the advantage that the rotational movement of the dispensing head relative to the adapter is converted into an axial movement in a structurally simple manner, which leads to a compression of the sealing insert via a wedge surface and thus to the liquid-tight sealing of the cavity.

This is achieved in a further development of said embodiment preferably achieved in that the second means comprise a acting in the relative rotation of the dispensing head and the adapter in an axial direction on the housing part wedge drive.

This measure has the advantage that the desired sequence of movements can be achieved with mechanically extremely simple elements that work reliably over long periods of time even under the harsh operating conditions in restaurants and the like.

The wedge gear is preferably arranged between the inner part and the housing part.

In further preferred variants of the exemplary embodiment, the inner part is elastically braced in relation to the housing part. This measure has the advantage that the parts of the adapter that move during the transition from the first to the second operating position automatically return to their starting position when the connection between the dispensing head and the adapter is released.

In a preferred development of this variant, the housing part is braced less in the first operating position and more in the second operating position relative to the inner part.

This measure has the advantage that even in the rest position, i.e. in the first operating position of the adapter, there are already defined relationships with regard to the position of the movable parts of the adapter, because these are pretensioned in a defined starting position.

The inner part is preferably braced relative to the housing part by means of an axially arranged spring.

This measure has the advantage that, by using a very simple mechanical element, reliable operation is also possible here under rough operating conditions, again with only low manufacturing costs.

A particularly good effect is achieved if the inner part has the surface partially delimiting the cavity, the first means also contain a first channel which opens into the surface, and finally the cleaning liquid can be introduced into the first channel. This measure has the advantage that the filling of the cavity with cleaning fluid is solved in a structurally simple manner.

This is particularly true when the first means further include a second channel and a valve in a further development of this embodiment, wherein the first channel is connected via the second channel with a feed for the cleaning liquid and the valve between the first channel and the second channel is arranged.

This measure has the advantage that the supply of the cleaning agent can be regulated within the adapter with a valve integrated therein.

In this case, a particularly good effect is achieved in that the valve can be switched from a closed position assigned to the first operating position to an open position assigned to the second operating position by rotating the dispensing head relative to the adapter.

This measure has the advantage that the supply of cleaning liquid takes place automatically by placing the tap on the adapter and locking it in place, while on the other hand the supply of cleaning liquid is automatically switched off again when the tap head is removed from the adapter. In a constructive implementation of this exemplary embodiment, an actuating element is provided for actuating the valve, which lies on the one hand on the valve and on the other hand on an inclined peripheral surface of the housing part.

This measure has the advantage that the desired actuation of the valve is also effected here by means of a simple wedge gear.

In further embodiments of the invention, the inner part is firmly connected to a lower part which is essentially fixed in space when used as intended, a tubular extension of the inner part being inserted into the lower part, a further channel connected to the first channel running through the extension and a pipeline at an angle is guided through the lower part and through the extension, the interior of which is connected to the further channel.

This measure has the advantage that the elements of the adapter that are spatially fixed when used as intended can be constructed in a structurally simple manner and can be fixed relative to one another by simply plugging them together.

This applies in particular if the further channel is the second channel.

In a preferred development of the exemplary embodiment mentioned above, the pipeline penetrates the lower part diametrically and is accessible at both ends. This measure has the advantage that the device according to the invention can be used for dispensing systems with several dispensing heads, because the pipeline can then form a section of a common supply line for the cleaning liquid. A number of adapters are then arranged side by side on a common bench, expediently in the immediate vicinity of the associated beverage kegs. Each tap head of each beverage keg can then be moved to its associated adapter and cleaned there.

If, in a further preferred embodiment of this exemplary embodiment, the pipeline is formed axially in several pieces, a further simplification of the assembly of the adapter is achieved.

Further advantages result from the description and the attached drawing.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the combination indicated in each case, but also in other combinations or on their own without departing from the scope of the present invention.

Embodiments of the invention are shown in the drawing and are explained in more detail in the following description. Show it:

1A shows a side view, partially broken away, of an exemplary embodiment of a device according to the invention in a starting position; FIG. 1B shows, on an enlarged scale, a section from FIG. 1A, illustrating a lower section of a commercially available tap head; FIG.

FIG. 2 shows the arrangement from FIG. 1A on a somewhat enlarged scale compared to FIG. 1A, but in a first operating position of the device according to the invention;

Fig. 3 is a representation as in FIG. 2, but for a second operating position of the device according to the invention.

In Fig. 1A, 10 designates a tap head of a commercially available type. The dispensing head 10 has an axis 11 which, when used as intended, is a vertical axis. At the top of the tap head 10 there is a lever linkage 12 with which the tap head 10 can be actuated when striking and knocking off a beverage keg, that is to say connected to or detached from a keg fitting. A beverage line 8 leading to a tap of a bar counter (not shown) and a gas line 9 for a conveying gas (C0 ₂ ) can be seen in the side view of FIG. 3.

At the bottom, the dispensing head 10 has a conical section 13, to which a lower section 14 connects at the bottom. This lower section 14 is primarily intended for connection to a barrel fitting or, in the context of the present invention, for connection to a cleaning adapter. As can be seen in particular from FIG. 1B, the lower section 14 consists of a collar-like extension 15 which is delimited on the outside by a cylindrical outer peripheral surface or line. At the bottom there is a radial end surface 17, which is partially formed by segment-like projections 18. These protrude radially inwards from the underside of the collar-like extension 15, but - seen over the circumference of the extension 15 - only in regions.

A thus formed recess 23 at the bottom of the pin Amplifier Unit 10 is formed by an axially recessed radial bearing surface 19, a cylindrical inner peripheral surface 20 and a lower radial surface 21 corresponding to the top of the segment-like protrusions 18th The latter still form a circumferential surface 22 radially on the inside.

In such conventional dispensing heads, the beverage line leads (not shown) 19 in the axial direction in the radial bearing surface This is placed on the keg fitting when striking a drum, wherein the beverage line then comes to the riser of the barrel in connection. The radial top surface 19 is therefore the area of the dispensing head 10 that most closely comes into contact with the beverage. Conventional cleaning devices or cleaning adapters are therefore limited to cleaning only this radial attachment surface 19.

At this point it should also be pointed out that "cleaning" naturally also includes processes such as rinsing and disinfecting in the present context. While the tap head 10 is of conventional design, a disinfection adapter 30 is described below which differs from the prior art according to the invention.

The disinfection adapter 30 according to FIG. 1A has a lower part 32, which is generally mounted fixed in space. As will be mentioned, it is particularly preferred to arrange a corresponding number of disinfection adapters 30 next to one another, for example on a suitably dimensioned bench, in the case of larger dispensing systems with several beverage barrels arranged next to one another.

For this purpose, a pipe 34 is provided which passes through the lower part 32 in the radial direction, relative to the axis 11. As indicated by dash-dotted lines, the tubing 34 is in Fig. 1A rightward and linJcs on, so that further deviated arranged disinfection adapters can be connected in series with respect to this conduit 34.

The lower part 32 contains an axial bore into which a tubular extension 36 of an inner part 38 projects. The tube-shaped extension 36 is provided at its lower end with a quear bore through which the pipe 34 is inserted. In this way, the lower part 32 and the inner part 38 are connected to one another both in a rotationally fixed and axially fixed manner. The pipeline 34 can also be formed in several parts in the longitudinal direction to simplify assembly. A sleeve-like housing part 40 runs on the inner part 38, as indicated by outer peripheral surfaces 42a and 42b. The housing part 40 also runs axially in the lower part 32, as indicated by an inner peripheral surface 44. The housing part 40 is elastically clamped with respect to the lower part 32 and the inner part 38 rigidly connected thereto, namely by means of a spring 50 which is arranged in corresponding annular grooves in the lower part 32 and the housing part 40. In the starting position shown in FIG. 1A, the spring 50 is relatively relaxed, so that a lower radial end face 52 of the housing part 40 bears against an upper radial end face 54 of the inner part 38. If, however, the housing part 40 is pressed down against the force of the spring 50 (cf. further below for FIG. 3), a lower radial end face 56 of the housing part 40 finally comes into contact with an upper radial end face 58 of the lower part 32. The housing part 40 can thus be moved between two axial stops, specifically against the force or with the force of the spring 50.

In the upper region, the housing part 40 encloses a sealing insert 60, which has the shape of a hollow cylinder upwards and has a lower annular shoulder 62 pointing radially inwards at the lower end. With this ring shoulder 62, the sealing insert 60 is axially fixed, but rotatably held in the inner part 38. An outer circumferential surface 64 of the sealing insert 60 bears in a form-fitting manner via an axial toothing or with friction against a complementary inner circumferential surface 66 of the housing part 40. The surfaces 64, 66 are essentially cylindrical. The inner circumferential surface 66 of the housing part 40, however, runs upwards into a conical taper 68, into which the 1A does not reach into the upper end of the sealing insert 60 in the basic position according to FIG. 1A.

The inner part 38 has an annular support surface 70 on its upper side, which extends around a central projection 71. Its upper radial end face is designated by 88.

The cleaning agent is supplied to the disinfection adapter 30 via an interior 80 of the pipeline 34. The interior 80 is connected to a first axial channel 82 in the tubular extension 36. This bends at its upper end by 90 ° and leads there to a valve 84 which is connected on its opposite side to a second channel 86, which in turn extends axially upward. This second axial channel 86 opens into the upper radial end face 88.

The valve 84 can be switched by means of an actuating element 90, the rear side of which bears against an inclined peripheral surface 92 of the housing part 40. The actuating element 90 is therefore displaced in the radial direction when the housing part 40 is rotated.

The operation of the device according to FIGS. 1A and IB will now be explained with reference to FIG. 2 (first operating position) and FIG. 3 (second operating position):

2 shows that the tap head 10 has initially been inserted loosely into the sealing insert 60 in the direction of the axis 11 from top to bottom until the radial end face 17 of the segment-like projections 18 on the annular support surface 70 of the inner part 38 touches down. The cylindrical outer circumferential surface or line 16 slides under friction on an inner circumferential surface 98 of the sealing insert 60.

In the embodiment shown in Fig. 2 position, a cavity 94 thus formed, which is limited by the radial bearing surface 19, the cylindrical inner peripheral surface 20, the lower radial surface 21 and the circumferential surface 22, each of the pin Amplifier Unit 10, and further through the annular bearing surface 70 as well as the outer circumference and the top radial face 88 of the central projection 71. This cavity 94 is determined by the interest in the present context and for a cleaning eligible surfaces 19, 20, 21 and 22 of the pin 10 with Amplifier Unit limited.

Around this cavity 94 is now a liquid-tight seal, the Zapfköpf 10 is rotated about the axis 11, as indicated by an arrow 100 in Fig. 2. The rotation is preferably 90 °. This rotation does the following:

Due to the frictional or a suitable positive connection between the cylindrical outer circumferential surface 16 of the extension 15 of the tap head 10 and the inner circumferential surface 98 of the sealing insert 60, this sealing insert 60 is carried along when the tap head 10 is rotated. The lower annular shoulder 62 of the sealing insert 60 slides in the annular groove of the inner part 38 receiving it. As a result of the positive or frictional engagement that also exists between the outer peripheral surface 64 of the sealing insert 60 and the inner peripheral surface 66 of the housing part 40, this also becomes effective when the tap head 10 rotates taken. As a result, the tap turns 10, the sealing insert 60 and the housing part 40 with each other in this phase.

If there is talk of "frictional engagement" in this context, then - as mentioned - it is to be understood both as abutting rough surfaces, as well as a toothing or other form-fitting connection that is effective to a certain extent.

3 shows that wedge surfaces 102a, 102b are provided between the housing part 40 and the inner part 38, which are preferably located on the circumference of the tubular extension 36. These wedge surfaces 102a, 102b are formed helically around the axis 11. They have the effect that the housing part 40 moves in response to rotation about the axis 11 relative to the inner part 38 and thus also to the lower part 32 downward, against the force of spring 50. This rotational movement continues until the already explained further above, Stop 56/58 is reached. In the case of an axial toothing between the sealing insert 60 and the housing part 40, the housing part 40 thus runs axially downward in this toothing, while the sealing insert 60 is axially fixed.

This axial downward movement of the housing part 40 does two things:

First, the sealing insert 60 slides with its outer circumferential surface 64 on the inner circumferential surface 66 of the housing part 40 relatively upwards until the upper end of the sealing insert 60 runs onto the conical taper 68. As a result, the upper part of the sealing insert 60 is pressed firmly against the outer circumferential surface of the collar-like extension 15 the consequence that the cavity 94 is closed liquid-tight.

On the other hand causes the axial downward movement of the housing part 40 such that the rear end of the actuating element 90 at the inclined peripheral surface runs along 92 and the operating member 90 so that in Fig. 2 and 3 is shifted to the right. A tab 104 of the actuator 90 then engages and opens the valve 84. In other words, the previously closed valve 84 is now opened automatically when the dispensing head 10 is rotated relative to the disinfection adapter 30. As indicated by arrows 106, cleaning fluid can now flow through the conduit 34, the first axial channel 82, the valve 84 therethrough and flows through the second axial channel 86 into the cavity 94 and the previously mentioned surfaces 19, 20, 21 and 22 at the lower Clean the end of the dispensing head 10.

The cleaning agent may be discharged from the cavity 94 by providing a connection to the beverage line 8 is formed. Then the tap at the other end of the beverage line is opened and a rinsing medium (water) is fed in until the entire cleaning agent is rinsed out of the beverage line 8.

If the dispensing head 10 is now turned back from the second operating position according to FIG. 3 into the first operating position according to FIG. 2, the housing part 40 moves upwards via the wedge surfaces 102a, 102b and with the support of the spring 50. The valve 84 then closes again automatically and the sealing insert 60 relaxes, so that the dispensing head 10 is without mechanical resistance can be removed from the disinfection adapter 30 again.

It follows from the above description that the cleaning process on the adapter 30 is completely independent of any actuation for striking the dispensing head 10. In particular, the lever linkage 12 does not need to be actuated to connect the dispensing head 10 to the disinfection adapter 30, and the gas line 9 does not have to be shut off.
