Description

[0001] The present invention relates to a suction nozzle for use on a suction device in a beverage preparation device according to claim 1. The invention further relates to a beverage preparation device comprising a suction nozzle according to claim 14.

[0002] Coffee and / or espresso machines with a milk module – which, unlike a simple steam wand that is immersed in a milk container, automatically draws in, heats, and / or froths milk – usually have the option of drawing in air through a suction nozzle and mixing it with the milk to create milk foam. For this purpose, air is drawn in through a suction nozzle and introduced into the milk. However, when introducing air into the milk, splashes can occur that can settle on the air baffle in the suction nozzle, potentially clogging the baffle and / or causing hygiene problems.

[0003] To prevent milk splashes from entering the intake port, prior art intake ports typically include a valve, such as a duckbill valve, to block milk splashes from entering the airflow channel from the side of the milk module. However, this presents a problem: a duckbill valve has a very narrow outlet opening, which is still directly affected by milk splashes and can quickly become clogged. This can hinder or even completely prevent the intake and introduction of air through the intake port. Consequently, such prior art intake ports require frequent cleaning and maintenance to maintain their functionality.

[0004] German patent DE 10 2018 211 677 A1 discloses a suction device for a beverage preparation device through which air can be introduced into a milk module, the airflow being regulated by a microporous material. US patent 2022 / 0257046 A1 discloses a beverage preparation device comprising a suction device for a milk module with a rotary knob, the rotary knob allowing the air supply to be increased and decreased.

[0005] Against this background, the object of the invention is to overcome the disadvantages of the prior art and in particular to propose an intake manifold which is resistant to clogging and thus reduces maintenance costs.

[0006] This problem is solved by an intake manifold having the features of claim 1. Furthermore, the problem is solved by a beverage preparation device having the features of claim 14.

[0007] Advantageous embodiments of the suction nozzle and the beverage preparation device according to the invention, comprising a suction nozzle according to the invention, are the subject of the following description and description of figures as well as the dependent claims.

[0008] The features disclosed by the device shall also be deemed to be disclosed and claimable by the corresponding procedure, and vice versa.

[0009] As mentioned above, the suction nozzle is intended for use on a suction device in a beverage preparation device, in particular a coffee or espresso machine with a milk module.

[0010] The intake manifold comprises a head element which includes at least one fastening section, preferably formed at an end facing away from the suction device, for fastening the intake manifold to the suction device and has an inlet opening through which air can enter the intake manifold along an axial direction (A), preferably be drawn in.

[0011] Furthermore, it is provided that the intake nozzle comprises a barrier element fluidly connected to the head element, which is designed in such a way as to prevent the entry of liquid, preferably splashes of a liquid to be foamed and / or heated, particularly preferably milk splashes, into the intake nozzle against the axial direction (A), and wherein an outlet opening is formed on the barrier element through which air can escape from the intake nozzle.

[0012] Furthermore, a fluid channel, preferably running along the axial direction (A), is arranged between the inlet opening and the outlet opening to guide the air through the intake nozzle.

[0013] According to the invention, a guide section is formed on the locking element downstream of the discharge opening, through which the air is guided into a pipe section of the suction device after exiting the discharge opening.

[0014] The intake manifold advantageously has an overall cylindrical appearance, whereby "cylindrical" in this context does not refer to a cylinder with a uniform outer circumference, but rather to a multitude of indentations and projections that may be provided on the outer circumference of the intake manifold.

[0015] The axial direction is understood to be the general direction, with respect to a cylindrical intake nozzle, running along or parallel to the central axis, along which air is actively drawn into the intake nozzle, in particular sucked in, and guided through the intake nozzle towards the point of contact with the liquid, preferably milk, to be foamed and / or heated. It is not excluded that the air may move in a direction other than this axial direction for a certain distance.

[0016] The intake manifold can be made from a variety of materials or material mixtures, preferably from a plastic, with the head element and the locking element being made of the same material or of different materials. Since the materials potentially come into contact with food, their compatibility and food safety are advantageous. It is also advantageous for the materials to be dishwasher-safe.

[0017] A guide section is defined as a section, preferably monolithic to the blocking element, through which the air flow is spatially restricted, directed, and controlled. Particularly preferably, the air is guided through the guide section directly after exiting the outlet opening, preferably deflected from the axial direction, thereby interrupting flow along the axial direction, at least partially. It is especially advantageous to deflect the air in two directions, particularly opposite directions, perpendicular to the axial direction, resulting in a split fluid flow. This prevents the entry of liquids or liquid splashes against the axial direction, as the splashes have a linear / ballistic trajectory and cannot follow the changes in direction imposed by the guide section.

[0018] The present invention has recognized that various problems are solved by means of a guide section downstream of the discharge opening, thereby advantageously preventing the discharge opening from becoming clogged.

[0019] The guide section prevents liquid splashes, especially milk splashes, from reaching the outlet opening and causing blockages. Since there is no risk of milk splashes coming into contact with the outlet opening, a larger outlet opening can be used, allowing air to be drawn through the intake nozzle more quickly and in greater volume. The guide section also ensures that the air exits the intake nozzle in a controlled manner, resulting in a particularly consistent frothing result. Furthermore, rinsing the guide section during manual cleaning is significantly easier than rinsing a valve.

[0020] According to a first advantageous embodiment, it can be provided that the guide section is designed to run at least partially along the axial direction (A) of the intake manifold.

[0021] This is particularly advantageous in order to achieve a rapid passage of air through the intake nozzle and to ultimately direct the air along the axial direction from the intake nozzle into the other parts of the milk module, especially for frothing milk.

[0022] According to a further advantageous embodiment, it can be provided that the guide section is arranged at least partially perpendicular to the axial direction (A) of the intake manifold.

[0023] This design advantageously achieves that the air is deflected from the axial direction at certain points, thus preventing the ingress of liquid or liquid splashes against the axial direction, as the splashes cannot follow the deflected fluid path. Advantageously, embodiments are also possible in which the orientation of the guide section is only approximately perpendicular to the axial direction at certain points, or angled at an inclination of less than 90°. Furthermore, this embodiment is particularly preferred for diverting the air into two, preferably opposite, directions immediately after it exits the outlet opening, thereby dividing the fluid flow.

[0024] According to a further advantageous embodiment, it can be provided that the guide section is arranged at least partially along the circumference of the intake manifold.

[0025] This design allows for particularly advantageous airflow, especially through sections where the airflow is deflected from the axial direction. Circumferential guidance has proven especially well-suited for a cylindrical intake manifold.

[0026] According to a further advantageous embodiment, the guide section may have at least one, preferably a plurality of, branches.

[0027] This design ensures that even when milk is being frothed vigorously, no milk splashes can reach the outlet of the intake nozzle. Furthermore, the branched design allows for particularly effective control of the airflow rate and volume.

[0028] According to a further advantageous embodiment, it can be provided that the guide section is formed at least partially on the outer circumference of the locking element, in particular as channels running along the edge.

[0029] Preferably, the outer boundary of the fluid flow of the air is ensured by the inner diameter of the suction device in which the intake nozzle is arranged.

[0030] This design makes the guide section particularly easy to clean. Preferably, the outer circumference of the guide section is adapted to the inner circumference of the suction device, so that the guide section comes at least partially close enough to the suction device that air can only pass through along the sides of the guide section at the designated openings, and liquid splashes cannot pass through in the opposite direction.

[0031] The previously described features work together particularly advantageously to form the guide section, in the broadest sense, as a labyrinth. The labyrinth formation can be achieved, in particular, by an arrangement of planes, wherein a first plane, especially one immediately downstream of the discharge opening, is followed in the axial direction by at least a second, more preferably a third, and most preferably a fourth plane. The surfaces of the planes are aligned parallel to each other. The planes are arranged as, preferably annular, extensions around a central, particularly cylindrical, axle shaft. Preferably, the first plane has lateral edge extensions through which the guide section is connected, particularly monolithically, to the upstream area of ​​the locking element.The planes advantageously have a certain distance from each other, whereby fluid channels are formed between the planes along the perimeter.

[0032] The planes advantageously feature channel-like openings, for example, as indentations at the outer edge of the plane and / or by varying outer circumferences and / or by lateral cuts in their, preferably round, outer circumference. This creates a lateral gap and / or channel at the edges of each plane through which air can flow axially to the next subsequent plane. Advantageously, the openings of each plane are formed in duplicate, mirror-symmetrically on opposite sides of the barrier element. The openings of the planes need not all have the same plane of symmetry, but can, for example, have planes of symmetry rotated by 1 to 90° around the circumference with respect to a first plane of symmetry.

[0033] Due to this labyrinthine design, the air, upon exiting the outlet opening, immediately encounters the first level, where it is deflected, preferably in two opposite directions, perpendicular to the axial direction. This deflection directs the air to one of the previously described passages, through which it passes along the axial direction to the subsequent level. Here, the air again encounters a level and is deflected, preferably in two opposite directions, perpendicular to the axial direction. After deflection, the air is guided along the circumference of the barrier element until it reaches the passage to the next, subsequent level. The branching of the guide section repeatedly splits and recombines the fluid flow.

[0034] According to a further advantageous embodiment, the head element and the locking element can be designed to be separable from each other, preferably completely.

[0035] This design is particularly advantageous for enabling easy and thorough cleaning of the intake manifold. It also allows for the replacement of individual components.

[0036] According to a further advantageous embodiment, it can be provided that the locking element at its end facing the head element and the head element at its end facing the locking element each comprise a connecting section, wherein the outer circumference of the connecting section of the locking element and the inner circumference of the connecting section of the head element are designed such that the locking element can be connected to the head element, preferably in the opposite direction to the axial direction A, in particular by being inserted and / or pushed into the head element.

[0037] This results in a particularly advantageous, intuitive and stable connection mechanism through the matching of the outer circumference of the locking element and the inner diameter of the head element, which also simultaneously achieves a seal of the connection between the locking element and the head element in the area of ​​the connection point.

[0038] According to a further advantageous embodiment, it can be provided that a bundle element, in particular an orifice, is arranged on the intake manifold, preferably in the area of ​​the connection point of the head element with the locking element, which has a smaller inner diameter than the inner diameter of the head element and / or the locking element.

[0039] This allows the drawn-in air to be concentrated and adjusted to a desired flow rate, which is particularly advantageous. Preferably, the orifice is interchangeable and can have different inner diameters, which can be adapted to the desired result.

[0040] According to a further advantageous embodiment, it can be provided that a first sealing element, in particular a sealing ring completely closed in the circumferential direction, is arranged in the area of ​​the connection point of the head element with the locking element.

[0041] This ensures, particularly advantageously, that the guided air at the connection point between the head element and the locking element follows only the desired fluid path. Preferably, the sealing element is designed as a separable and replaceable component. However, embodiments in which the sealing element is integrated with the head element or locking element as a sealing tab are also conceivable.

[0042] According to a further advantageous embodiment, it can be provided that at least a second sealing element, preferably completely closed in the circumferential direction, is arranged on the outer circumference of the head element.

[0043] This design further improves the sealing of the intake manifold and makes its arrangement within the suction device particularly stable. The sealing element can advantageously also be designed as a sealing tab, with the head element particularly advantageously having a recess in which the sealing tab can be recessed.

[0044] According to a further advantageous embodiment, the fastening section of the head element can be designed in a dome-like, in particular mushroom-shaped, form.

[0045] This design is particularly well-suited for use with a cylindrical suction device, ensuring a tight seal, especially a secure fit, between the fastening element and the suction device. Alternatively, other designs for the fastening section are possible, for example, a largely flat surface with a grip tab or ring, with the dome-shaped design being particularly preferred.

[0046] According to a further advantageous embodiment, it can be provided that at least two projections, in particular pins, are formed on the outer circumference of the locking element and at least two recesses shaped complementarily to the projections are formed on the inner circumference of the head element.

[0047] This design further supports the connection of the locking element with the head element, particularly in the axial direction, with the features preferably snapping into the recesses, especially reversibly, ensuring that the connection remains stable even under high pressure from flowing air.

[0048] Furthermore, the above-mentioned problem is solved by a beverage preparation device with a suction device, preferably a coffee and / or espresso machine with a foam module, comprising a suction nozzle according to the invention.

[0049] To avoid unnecessary repetition, reference is made to the above-described suction nozzle with regard to the advantageous effects and the advantageous design of the beverage preparation device.

[0050] In summary, the invention enables the proposal of a beverage preparation device with a suction module and a suction nozzle according to the invention, which is resistant to clogging and thus reduces maintenance effort.

[0051] The present invention will now be explained in more detail with reference to drawings that are merely schematic and exemplary embodiments of the invention.

[0053] The head element 3 of the intake manifold 1 also has an inlet opening 5 through which air can be drawn in, and in particular drawn into, the intake manifold 1 along the axial direction A. A fluid channel 8 is formed in the head element 3 and in the locking element 6, which adjoins the head element in the axial direction, through which the air can be guided, particularly in the axial direction A, through the intake manifold. The head element 3 and the locking element 6 are preferably designed to be separable from one another, with the locking element 6 being insertable and / or detachable at a connecting section opposite the axial direction A into a connecting section of the head element to form a connection point 16. Advantageously, the inner diameter of the head element 3 and the outer diameter of the locking element 6 are matched to each other such that the connection is stable and leak-proof.The locking element 6 preferably has projections 13 which can be arranged in complementary recesses 19 on the head element 3. A baffle 10 is arranged at the connection point 16 between the locking element 6 and the head element 3. This baffle focuses the flowing air and can have an inner diameter adapted to the desired flow velocity. Furthermore, a first sealing element 11 is arranged at the connection point 16 between the locking element 6 and the head element 3. This sealing element is preferably designed as a circumferentially completely closed and separable sealing ring, although an embodiment as an inseparably arranged sealing tab is also conceivable.A second sealing element 12 can also be arranged on the outer circumference of the head element 3, which further improves the tightness of the intake manifold and is preferably designed as a sealing ring or sealing tab that is completely closed in the circumferential direction and is advantageously recessed in a recess of the head element 3.

The first plane 15 has lateral edge extensions 18 through which the guide section 9 is monolithically connected to the upstream area of ​​the locking element 6. The planes 15 are spaced apart from each other, forming peripheral channels between the planes 15 along the circumference.The planes 15 also feature channel-like openings, formed as indentations at the outer edge of the planes 15 and by lateral cuts in their otherwise round outer circumference. This creates a lateral gap and / or channel at the edges of each plane 15, through which air can flow along the axial direction A to the next subsequent plane 15. The openings of each plane 15 are formed in duplicate, mirror-symmetrically on opposite sides of the barrier element 6, with not all planes 15 sharing the same plane of symmetry.

[0055] The Fig. Figure 2 shows a locking element 6 according to the invention lying on its side.

The locking element 6 has a guide section 9 which extends at least partially along the axial direction A, at least partially perpendicular to the axial direction A, and at least partially along the circumference of the intake manifold 1.

[0056] The guide section 9 is designed as a labyrinth by an arrangement of four planes 15 sequentially in the axial direction A. The surfaces of the planes 15 are aligned parallel to each other, and the planes 15 are arranged as annular extensions around a central, cylindrical axle shaft 17. The first plane 15 has lateral edge extensions 18, through which the guide section 9 is monolithically connected to the upstream area of ​​the locking element 6. The planes 15 are spaced apart from each other, forming peripheral channels between them along the circumference. The planes 15 also have channel-like openings, formed as indentations at their outer edges and by lateral cutouts in their otherwise round outer circumference.This creates a lateral gap and / or channel at the edges of each plane 15, through which air can flow along the axial direction A to the respective downstream plane 15. The openings of each plane 15 are formed in duplicate, mirror-symmetrically on opposite sides of the barrier element 6, whereby not all planes 15 share the same plane of symmetry.

[0057] The Fig. Figure 3 shows a locking element 6 according to the invention in a side view. The locking element 6 has projections 13 which can be arranged in complementarily shaped recesses 19 in the head element 3 (not shown) to facilitate the connection between the locking element 6 and the head element 3. Furthermore, a discharge opening 7 is formed on the locking element 6, through which the guided air can exit the intake nozzle 1 and is subsequently guided through the guide section 9.

[0058] The guide section 9 is designed as a labyrinth by an arrangement of four planes 15 sequentially in the axial direction A. The surfaces of the planes 15 are aligned parallel to each other, and the planes 15 are arranged as annular extensions around a central, cylindrical axle shaft 17. The first plane 15 has lateral edge extensions 18, through which the guide section 9 is monolithically connected to the upstream area of ​​the locking element 6. The planes 15 are spaced apart from each other, forming peripheral channels between them along the circumference.

The openings of each plane 15 are formed in duplicate, mirror-symmetrically on opposite sides of the barrier element 6, whereby not all planes 15 share the same plane of symmetry.

[0059] The Fig.Figure 4 shows a perspective view of the intake manifold 1 according to the invention, comprising a head element 3 with a fastening section 4 and a locking element 6 with a guide section 9. The fastening section 4 is preferably dome-shaped, in particular mushroom-shaped, although other embodiments, for example with a grip tab or a grip ring, are also conceivable. The head element 3 and the locking element 6 are preferably designed to be separable from one another, wherein the locking element 6 can be inserted and / or detached at a connecting section opposite the axial direction A into a connecting section of the head element to form a connection point 16. Advantageously, the inner diameter of the head element 3 and the outer diameter of the locking element 6 are matched to each other such that the connection is stable and leak-proof.The locking element 6 preferably has projections 13 which can engage in complementary recesses 19 on the head element 3.
