Description

[0001] The present invention relates to a storage container for cleaning agents, comprising a housing and a connector for connection to a cleaning device of a coffee machine's flow line system. The present invention also relates to a coffee machine with such a storage container for cleaning agents.

[0002] Storage containers for cleaning agents and coffee machines with such storage containers are known, for example, from WO 2013 023 963 A1 and EP 2 705 784 A1. Such storage containers typically contain cleaning agents and are designed for connection to a cleaning device of a coffee machine's flow line system. These storage containers are designed to be removable, for example, for refilling or replacing the cleaning agent after it has been used up. These known storage containers have a bayonet lock for detachable connection to the cleaning device.

[0003] A disadvantage of these known storage containers for cleaning agents is that their operation is not intuitive for less technically proficient operators. In particular, the direction of rotation for releasing the bayonet connection, and possibly also for establishing the bayonet connection, is not recognizable. In particular, the type of connection in the connected state and the direction of rotation required to release the bayonet connection are not intuitive or even recognizable at all.

[0004] The object of the present invention is therefore to further improve a storage container for cleaning agents or a coffee machine with such a storage container, in particular to facilitate the handling of the storage container.

[0005] This object is achieved by a storage container for cleaning agents having the features of claim 1 and also by a coffee machine having the features of claim 10. Advantageous developments of the invention are the subject of the dependent claims.

[0006] A corresponding storage container for cleaning agents comprises a housing and a connection for connection to a cleaning device of a flow line system of a coffee machine. The housing has an end face, wherein the connection is arranged on a rear side of the housing, which is opposite the end face. According to the invention, the end face is delimited by at least three edges, wherein two of the edges opposite one another along the end face run parallel to one another. Alternatively or additionally, at least two of the edges that delimit the end face run at an angle of less than or equal to 90° to one another. This makes it intuitively recognizable, even for less technically experienced operators, that a rotational movement or a direction of rotation is not required to release the storage containers.Due to the arrangement of the edges of the front side, an operator can intuitively grasp the storage container 1 at a gripping area, but immediately recognizes that the storage container cannot be removed by a rotating movement. Rather, the only intuitive movement that remains is a translational movement, e.g. pulling, possibly with an additional directional component directed upwards or downwards. This enables intuitive and, in particular, easier handling. The arrangement of the edges according to the invention enables, e.g. by an increasing distance between the edges away from a holding means, and additionally supported by the aforementioned angles, an operator to intuitively arrive at a direction of movement for releasing the connection that acts even more in the direction of a release direction of the holding means. This further simplifies handling of the storage container.

[0007] A cleaning agent storage container is understood to mean, in particular, a cartridge, which can be designed as a disposable cartridge, in particular with a storage fill or a lifetime fill, or as a reusable or refillable cartridge. In particular, a cleaning agent storage container is understood to be such if it is suitable for storing a cleaning and / or descaling agent for multiple cleaning processes of a coffee machine.

[0008] A cleaning agent is understood to mean, in particular, any agent that can contribute to reducing plant, oily, protein-containing, or greasy deposits in the flow line system, particularly within a brewing device or milk system, or that also has a protective effect on parts of the flow line system during cleaning, e.g., seals or metallic components, such as a care product. However, a cleaning agent is also understood to mean, in particular, a descaling agent that can contribute to reducing limescale deposits in the flow line system, particularly within a heating device.

[0009] Opposite sides of the housing, particularly in the case of the front side and the rear side opposite it, should not only be considered sides whose surface normals are strictly parallel, but rather the sides that are opposite a housing surface, especially even if the surface normals are at an angle of up to 45° to each other, for example, or if the surfaces include uneven areas.

[0010] In an advantageous development of the solution according to the invention, a gripping area for handling the storage container when establishing and / or separating the connection to the cleaning device runs along at least two of the edges and / or extends onto side surfaces of the housing that abut at least two of the edges. This makes it clear and intuitive, even for less technically experienced operators, that a rotational movement and further knowledge of a correct rotational movement for releasing and removing the storage container is not required. Rather, it is immediately apparent that only a translational movement, possibly with an additional vertical component, is necessary to release the connection. This further simplifies handling of the storage container. By extending onto the side surfaces, it is easier to grasp and thus further improves handling.

[0011] In a further advantageous development of the inventive solution, the connection comprises a connecting piece. Thus, the direction of handling of the storage container is also determined by the shape of the connecting piece. Due to the arrangement of the edges of the front side, the grip area is particularly advantageously adapted to the direction of handling determined by the connecting piece. This enables even more intuitive handling of the storage container.

[0012] In a further advantageous development of the inventive solution, the connection is formed entirely by a single connecting piece. Since connecting pieces typically engage seals, which then also exert a holding force, the development with a single connecting piece makes it possible to minimize this holding force. This ensures that only a minimal holding force needs to be overcome when removing the storage container. This further simplifies handling of the storage container.

[0013] In a further advantageous development of the solution according to the invention, the housing has a holding means between the front and the rear, which is designed to secure the storage container in the connection with the cleaning device of the flow line system of the coffee machine. This not only allows the storage container to be held in a defined connection, e.g., in a connection with a cleaning device of a flow line system of a coffee machine. Rather, it also enables haptic feedback to an operator that the storage container has been fully inserted into the connection, i.e., has been correctly inserted. This not only enables safe operation, but also particularly intuitive handling of the storage container.

[0014] The grip area can be distinguished from the front and / or back by its surface texture, framing, color, and / or design. This allows the grip area to be designed particularly prominently and thus easily perceived by operators.

[0015] In a further advantageous development of the inventive solution, the handle area has the same surface structure as the front and / or back. This allows the handle area to be designed particularly discreetly. On the other hand, it is less likely for operators to perceive the handle area as being too small or too large, because the transition can be designed smoothly. This can have a positive effect on the perception of handling the storage container.

[0016] In a further advantageous development of the solution according to the invention, two of the edges opposite one another along the front side run parallel to one another, and two of the edges run at an angle of less than or equal to 90° to one another, and two of the edges run at an angle of greater than or equal to 90° to one another. This makes it very easy, on the one hand, to ensure that the storage container stands securely on a surface, and on the other hand, in a housing with vertical walls at one end of the front side, preferably at the bottom or at the level of the connection and / or the holding means, more space for gripping the storage container can be easily provided. This enables intuitive gripping of the storage container at the most effective point and therefore further facilitates and intuitive handling.

[0017] In a further advantageous development of the inventive solution, the storage container contains a water-soluble cleaning and / or descaling agent. This maximizes the concentration of the stored agent and thus minimizes the weight of the storage container over a defined service life. This facilitates handling of the storage container.

[0018] In a further advantageous development of the solution according to the invention, at least two of the edges of the front side are rounded. This not only makes gripping the storage container easier, but also makes it particularly comfortable for the operator. Furthermore, the available space for gripping can be maximized when inserting and / or removing the storage container into or from a housing with vertical walls. This further simplifies handling of the storage container.

[0019] The stated object is also achieved by a coffee machine with a flow line system and a cleaning device, in which the cleaning device has at least one storage container according to the invention and / or is configured to accommodate a storage container according to the invention. Since cleaning is frequently required in coffee machines, the aforementioned advantages are particularly evident here and therefore positively influence the perception of handling and the so-called user experience (UX) of the entire coffee machine.

[0020] A coffee machine is defined in particular as any machine capable of preparing coffee beverages. This particularly applies to fully automatic coffee machines with grinders, which can prepare various coffee beverages fully automatically and may therefore require even more frequent cleaning, thus having an even more positive impact on the handling of the entire fully automatic coffee machine and the user experience.

[0021] Further advantages and advantageous configurations result from the following in connection with the Fig. 1 to 4. They show: Fig. 1 a schematically illustrated embodiment of a storage container according to the invention in a perspective side view / rear view, Fig. 2 an embodiment of the storage container from Fig. 1 in perspective front view / side view, Fig. 3 an embodiment of the storage container from Fig. 1 in side view, and Fig. 4 a schematically illustrated embodiment of a coffee machine according to the invention with a storage container according to the invention in a perspective side view / front view.

[0022] In Fig. Figure 1 shows a schematically illustrated embodiment of a storage container 1 according to the invention in a perspective rear view. It shows a storage container 1 for cleaning agents, with a housing 2 and with a connection 3 for connection to a cleaning device 4 of a flow line system of a coffee machine 5, which is only Fig. 4 can be seen. The housing 2 has a Fig. 1 not visible front side 21, wherein the connection 3 is arranged on a rear side 22 of the housing 2 opposite the front side 21.

[0023] The front side 21 is in Fig. 2 and is delimited by at least three, in the present example four edges 23, 24, 25, 26. Two edges 23, 24, 25, 26, which are opposite one another along the end face 21, run parallel to one another. In addition, two, namely the upper edge 23 and the left edge 25, run at an angle of less than 90° to one another. In addition, the upper edge 23 and the right edge 26 run at an angle of less than 90° to one another. The angles between the lower edge 24 and the left edge 25 as well as the right edge 26 are both greater than 90°. Alternatively (not visible in the drawing), for examplethe lower edge 24 may also be inclined relative to the upper edge 23, so that the angles between the upper edge 24 and the left edge 25 and the right edge 26 are each less than 90° and the angles between the lower edge 24 and the left edge 25 and the right edge 26 may be different and one of these two angles may also be less than 90° and the other of these two angles may be greater than 90°.

[0024] A grip area 6 for handling the storage container 1 when making and / or breaking the connection with the (only in Fig. 4) runs along the left edges 25 and the right edge 26 and extends on side surfaces of the housing 2, which abut the left edge 25 and the right edge 26, respectively. As shown in the Fig. 1 and Fig. As can be seen in Figure 2, two edges, namely the left edge 25 and the right edge 26 of the front side 21, are rounded. The handle area 6 has the same surface structure as the front side 21 and the rear side 22 and is therefore not clearly visible in the figures. However, it is intuitively apparent from the design of the storage container 1.

[0025] For example, in Fig. 2, the side surfaces of the housing 2 can have vertical grooves, which are designed, for example, as drainage channels for draining liquid from an overflow of the storage container 1. Such a feature should not be understood here as a limitation of a surface or side, in particular not as a limitation of a side surface, an end face 21, or a rear face 22. However, it could serve to unobtrusively limit the extent of the handle area 6.

[0026] As in Fig. 3, the storage container 1 comprises a connection piece 31 as connection 3. In the present example, the connection 3 is formed entirely by a single connection piece 31. Likewise, in Fig. 3 that the housing 2 has a holding means 7 between the front side 21 and the rear side 22, which is designed to fix the storage container 1 in the connection with the cleaning device 4 of the flow line system of the coffee machine 5, as shown in Fig. 4 is recognizable.

[0027] In Fig.4 shows a coffee machine 5 having a flow line system (not shown) and a cleaning device 4. The cleaning device 4 here has two storage containers 1, wherein the left and slightly larger of the two storage containers 1 is shown removed for refilling or replacement. In contrast, the right and slightly smaller of the two storage containers 1 is inserted and shown secured by the holding means 7 in connection with the cleaning device 4 of the flow line system of the coffee machine 5. Even if it is not apparent from the figures, the left of the two storage containers 1 shown contains a water-soluble descaling agent and the right of the two storage containers 1 shown contains a water-soluble cleaning agent.

[0028] Due to the inventive design of the storage container 1, even less technically experienced operators can intuitively recognize that a rotational movement or knowledge of the direction of rotation required to release the storage container 1 is not necessary. Due to the arrangement of the edges 23, 24, 25, and 26, in particular the left edge 25 and the right edge 26, an operator can intuitively grasp the storage container 1 at the grip area 6 and recognize that a translational movement is required. This enables intuitive and, in particular, simplified handling.

[0029] The components illustrated in the exemplary embodiment, such as the storage container 1 and the handle area 6, as well as their relative sizes, are generally not to be considered to scale. Rather, individual elements, such as the fluid connection 3 and the holding means 7, may be illustrated as exaggeratedly thick or large for clarity and / or clarity. The explanation of the storage container 1 according to the invention based on the described exemplary embodiments is not to be considered a limitation of the invention to these. Rather, the invention encompasses any novel feature and any combination of features, even if this feature or combination itself is not explicitly stated in the patent claims or the exemplary embodiments.
