    description
    Field of the invention The invention is in the field of household appliances, in particular household appliances that come into contact with food, and relates to a device for the continuous mixing of at least a first and a second fluid to form a liquid end product, a plant with two such devices and a use of this device or system according to the independent claims.
    Background Mixing devices for the production of beverages are known. Some devices work according to the metering principle by mixing a prescribed amount of one fluid with an amount of another fluid and then dispensing it. Other devices are also designed for the continuous delivery of a mixture, but the complexity of such known devices is considerable and they are therefore associated with high acquisition costs. Mixing devices are also known which can output different mixtures, depending on which input fluids are selected.
    DESCRIPTION OF THE INVENTION It is an object of the invention to make the mixing of beverages more flexible and to simplify a corresponding device.
    This object is achieved in a first aspect of the invention with an inventive device for the continuous mixing of at least a first and at least a second fluid to form a liquid end product. The device according to the invention comprises at least one first input line for feeding the first fluid into the device and at least one second input line for feeding the second fluid into the device. An output line for dispensing the liquid end product to a user is also provided, which is connected to the first and second input lines in a connection area arranged within a housing of the device. The device can be connected to a first source for the first fluid, from which the first fluid can be fed into the first input line. In the connection area, a final diameter of the first input line is larger than an initial diameter of the output line. A diameter of the output line increases in the direction of a flow of the end product along a section of the output line from the initial diameter until it is greater than or equal to the end diameter of the first input line.
    The inventive device has the advantage of a simple structure and uses the so-called. Venturi effect. At the same time, in contrast to known solutions, it is not restricted by a metered delivery of the end product, but can continuously provide the end product. As a result, the user is more flexible in the choice of dispensing quantity and does not have to initiate several mixing processes in order to achieve the desired end product.
    Preferably, the diameter of the output line in the initial section of the output line increases such that in the initial section an increase between 6% and 7.5%, in particular of 7%, based on a longitudinal axis of the output line, can be realized. This slope advantageously results in the best possible use of the Venturi effect for mixing the fluids. A 1: 3 mixture is possible (1 part syrup to 3 parts water).
    In one embodiment of the device, it is particularly preferred to arrange a pipe adapter in the connection area, which connects the first input line to the output line. The pipe adapter has a diameter which is smaller than the diameter of the outlet pipe which prevails at the end of the slope, viewed in the direction of the flow of the liquid end product. It is preferred that this diameter is between 3 and 4.5 times smaller. It is particularly preferably 4 times smaller. The use of the pipe intermediate piece enables the activation of the mixing function of the device according to the invention to be set as a function of the flow rate of the first fluid, which is explained in more detail in connection with the exemplary embodiments of the invention.
    The object is achieved in a second aspect of the invention with a system comprising a first and a second device according to the first aspect of the invention. The first device is designed to provide a first fluid mixture, the output line of the first device being connected to the first input line of the second device, so that the first fluid mixture as the first fluid for the second device can flow into the first input line of the second device.
    The system allows maximum flexibility with regard to the mixing options, since it allows most fluid combinations.
    In a third aspect of the invention, the object is achieved by using the device according to the first aspect of the invention or the system according to the second aspect of the invention. To mix a drink, the second fluid is first provided for the device. The second fluid of the first device and / or the second fluid of the second device is initially provided for the system. The device or the first device of the system with the respective first input line is connected to a tap, the mixing of the respective dispensing fluid of the corresponding device being triggered by opening the tap to more than 30%. On the other hand, the tap can be opened less than 30% for cleaning the device or the system or for delivering unmixed water.
    Advantageously, the device is designed such that, in addition to the main task, i.e. the mixing of fluids, in particular beverages, it also meets requirements for use in the food industry, i.e. it can also be operated for self-cleaning without the need for additional elements or time-consuming disassembly.

    WAYS OF CARRYING OUT THE INVENTION In the figures, the same reference symbols designate the same or the same components.
    Definitions [0014] In the present sense, a fluid can be liquid or gaseous. The fluids are assumed to be consumable fluids for the purposes of the present invention, but other fluids could also be used. Furthermore, the term “fluid” can also be understood as a mixture of two or more additional fluids and should not be interpreted as limiting in comparison to an explicit use of the term “fluid mixture”.
    The terms “end” and “start” are to be understood in the context of lines in the direction of the flow of the respective liquid.
    Fig. 1 shows a sectional view of a first embodiment of the device according to the invention and Fig. 2 shows the detail D from Fig. 1. The device 1 is used for the continuous mixing of at least a first and a second consumable fluid 26, 27 to a liquid end product 28, especially a drink.
    For the following description it is assumed that the first fluid is water and the second fluid is syrup. The device 1 comprises a housing 2, a first input line 6 for feeding the water 26 into the device 1 and a second input line 8 for feeding the syrup 27 into the device 1. The water 26 is to be mixed with the syrup 27, to produce a drink 28, i.e. the end product. An output line 4 is also provided for the delivery of the beverage 28 to a user. The output line 4 is connected to the first and second input lines 6, 8 in a connection area V arranged inside the housing 2. The device 1 can be connected to a first source 29 for the water 26, from which the water 26 can be fed into the first inlet line 6. Typically, the first source is a conventional water connection in a kitchen.
    For reasons of simplicity, the term drink is used as soon as the water comes into contact with the syrup, although at this point in time the two liquids have not been completely mixed. In other words, the outlet line 4 carries the drink 28 from the beginning. Of course, the two liquids mix better and better as they flow through the outlet line 4 towards a beverage container 4a.
    The device 1 further comprises a flexible food hose 8c, which connects the second input line 8 to a second source 8a, which is typically a container for the syrup 27, so that the syrup 27 from the second source 8a through the food hose 8c in the second input line 8 can be drawn in. In this embodiment, the syrup container 8a is conveniently attached or suspended from a hook 31 of the device 1. Alternatively, the syrup container 8a can be attached directly to the food hose 8c by means of a stopper. Other mounting options are also conceivable. The special design of the hose 8c as a food hose takes account of the fact that the device 1 is a food-carrying device which, in contrast to, for example, industrial devices, has special hygiene requirements. Therefore, for the hose 8c e.g. uses a material that has an antibacterial effect.
    In the connection area V, a final diameter of the first input line 6 is larger than an initial diameter of the output line 4. A diameter of the output line 4 becomes larger in the direction of a flow of the beverage 28 (arrow in the output line) starting from the initial diameter along a section of the output line 4 until it is greater than or equal to the final diameter of the first input line 6. The increase in the diameter of the output line 4 is identified in FIG. 1 by reference 4b. The diameter of the output line 4 in this initial section increases in such a way that a gradient between 6% and 7.5%, in particular of 7%, based on a longitudinal axis of the output line 4, can be achieved.
    Due to the different diameters of the first input line 6 and the output line 4 at their connection point, the device 1 uses the Venturi effect already mentioned. In other words, the speed of the water increases in this area. This creates a negative pressure which causes the syrup 27 to be sucked out of the syrup container 8a through the food hose 8c and the second inlet line 8 into the connection region V and mixes with the water. This eliminates the need for a pump that would otherwise have to pump the syrup into the connection area V.
    In the present embodiment of the device 1, a pipe intermediate piece 5 is preferably arranged in the connection area V, which connects the first input line 6 to the output line 4. The pipe intermediate piece 5 has a diameter which is smaller than the final diameter of the first input line 6 in the connection region V, preferably by a factor between 0.6 and 0.8, most preferably by a factor of 0.73. The diameter of the pipe intermediate piece 5 is preferably constant. Furthermore, the diameter of the pipe intermediate piece 5 is preferably also smaller than the initial diameter of the outlet line 4. The pipe intermediate piece 5 serves to regulate the suction effect (Venturi effect) of the syrup 27 from the syrup container 8a, to the extent that the suction effect only when a certain flow rate has been reached or Flow rate of water 26 occurs. In other words, the pipe intermediate piece 5 enables the device 1 to be used as a mixing device or only as an “extension” of the first inlet line 6. This has the advantage, on the one hand, that the device does not have to be removed every time only water is required. On the other hand, an effective cleaning (called “cleaning-in-place” (CIP)) of the outlet line 4 can be carried out with it. This may be desirable, for example, if a beverage has been mixed and then only water is required, or for basic cleaning after each use of the mixing property. Specifically, this means that if the faucet vm50 is only opened to a certain point, the water flows through without mixing and cleans the outlet line 4. The pipe intermediate piece thus also contributes to the suitability of the device 1 as a food-carrying device. The above information for the diameter of the pipe adapter 5 has been determined on the basis of experiments. It has been shown that the above-mentioned factor of 0.73 establishes a threshold between the delivery of unmixed water and the onset of the mixing action when the faucet vm50 is opened by approximately 30%. On the one hand, this means that a sufficient water flow without mixing is achieved with approx. 30% and on the other hand that the desired setting (water / drink) is easy for the user to make. Obviously, however, other factors can also be selected for the diameter of the pipe intermediate piece 5, in particular in the range specified above.
    It is noted that an effect of the pipe adapter 5 in the sense of cleaning can also be achieved without this by making the difference between the final diameter of the first input line 6 and the initial diameter of the output line 4 smaller. In this case, however, this effect is not so pronounced.
    The device 1 further comprises a first valve 8b, which is arranged in the second input line 8. The second input line 8 opens into the output line 4 at the beginning thereof. The first valve 8b serves to prevent a flow of the beverage 28 or the water into the second inlet line 8 and thus into the syrup container 8a. The first valve 8b is preferably an adjustable ball check valve 8b, which is simple and inexpensive to implement. The adjustable ball check valve 8b is only raised when the device 1 is in operation when there is sufficient negative pressure (Venturi effect) coming from the outlet line 4, so that the syrup can be drawn into the outlet line 4. If this negative pressure is not reached, the ball check valve 8b closes the second input line 8 due to its weight. The selection of the material of the ball of the ball check valve 8b thus also influences to a certain extent the threshold for dispensing the syrup. The ball is preferably made of chrome steel, since this material ensures a reliable closing action due to the relatively high mass. But it could also be made of a suitable plastic.
    The device 1 further preferably comprises a control element vm40, which is designed to change the flow cross section of the food hose 8c in order to control a flow rate of the syrup 27 through the food hose 8c. The control element vm40 is preferably also designed to completely interrupt the flow of the syrup 27 into the second input line 8. It is further preferred that the interruption of the flow by means of the control element vm40 takes place independently of the presence or absence of the water in the first inlet line 6 and / or the drink in the outlet line 4. If the food hose 8c is not narrowed, the maximum amount of syrup 27 per unit of time is specified, which, when the diameters described above are selected in the connection area V, means approximately 1 part of syrup with 3 parts of water. However, mixtures with water proportions between 3 and 20 parts are possible with the device according to the invention. Another advantage of the control element vm40 is that when the syrup dispensing is completely interrupted, the device 1 only carries water even when the water tap vm50 is completely open. Thus, the user is not limited by the above-mentioned threshold of, for example, approximately 30% opening of the faucet vm50 with regard to the discharge of unmixed water.
    The device 1 preferably further comprises an adapter element 40 for connecting the device 1 to the faucet vm50. The adapter element 40 is preferably interchangeable with another adapter element for a different connection type. In this way, the device can advantageously be adapted to different end pieces of water connections.
    Fig. 3 shows a circuit diagram of the first embodiment of the inventive device 1. The first input line 6 is dimensioned so that it water at a temperature between 5 and 20 ° C in an amount of 8 to 101 / min at about 4 bar can lead. The food hose 8c and the second inlet line 8 are dimensioned such that they can carry syrup at a temperature of approximately 20 ° C. in an amount between 0.1 and 3 l / min at a pressure between -0.1 and -1 bar , The pressure values refer to the suction effect caused by the Venturi effect and are therefore indicated with a minus sign.
    Fig. 4 shows a circuit diagram of a second embodiment of the device 1 according to the invention. In this embodiment, the second fluid is carbon dioxide instead of syrup. In this embodiment, the device is used to dispense the end product, that is, sparkling water (H2O + CO2).
    The same dimensioning as for the first embodiment applies to the first input line 6. A flow monitor x1 (flow sensor) is connected in the first input line 6 and downstream of the flow monitor x1 (flow sensor) in front of the connection area V is a pump 7, e.g. a 100 watt pump. As soon as the flow monitor x1 detects a flow of water by opening the tap vm50, it switches on the pump 7. The water flows through the connection area V into a buffer tank 6a which is connected in the outlet line, the pump 7 initially only supporting the water flow in addition to the line pressure from the water source 29. The buffer tank 6a serves to enrich the water with CO2 by recirculation.
    The container 8a is in this case a pressure container for carbon dioxide. It is connected to the second input line 8, a pressure reduction station 13 being provided which keeps the pressure, and thus the quantity, CO2 constantly adjustable. For example, this regulates the pressure to 3 to 4 bar. Furthermore, a safety valve vs73 is provided in the second input line 8 in order to reduce any excess pressure. The second input line 8 then opens into the second output line 4 in the connection region V.
    The control element in this case is a tap vm40, by means of which the CO 2 supply can be regulated or completely interrupted, similarly to the first embodiment.
    Furthermore, a valve 8b is also provided in this case, which prevents a return flow from the end product into the second inlet line 8.
    The buffer tank 6a has, in addition to its first output in the output line 4, a second output in its base area, which is connected to a first feedback line 11a, which in turn opens into the first input line 6 upstream of the pump 7. Furthermore, the buffer container 6a has a third outlet in its upper region, which is connected to the second inlet line.
    In the output line 4 downstream of the buffer tank 6a, a flow controller vm61 is provided, with which the amount of the sparkling water 28 can be regulated.
    If sparkling water is now to be generated, the control element vm40 and the water tap vm50 are opened. As soon as the flow monitor x1 detects a flow of water, it switches on the pump 7. The water flows through the connection area V into the buffer tank 6a, the pump 7 initially only supporting the water flow in addition to the line pressure from the water source. Now two operating modes are possible for sparkling water. In a first operating mode, the flow regulator vm61 in the output line 4 is opened. Consequently, the water flows through the connection area V into the buffer tank 6a, which e.g. has a volume between 0.11 and 11, CO2 being sucked into the connection area V from the second inlet line (Venturi effect) and mixed with the water. The water enriched with CO2 in this way can flow at the exit into the container 4a for consumption. In this operating mode, only slightly water enriched with CO2 is emitted, since only a part of the CO2 mixes with the water in a single water pass.
    In a second operating mode, the flow controller vm61 is closed. In this case, more CO2-enriched water can be released, as explained below. Because the flow controller vm61 is closed (means are provided to vent any air in the lines), the buffer tank 6a fills with sparkling water, with a portion of the CO2 outgassing from the sparkling water in the upper region of the buffer tank 6a. As soon as a system pressure is reached in the entire line system or the water tap vm50 is closed, the pump 7 takes over the task of recirculating the water, which has already been partially enriched with CO2, from the buffer tank 6a via the first feedback line 11a back into the buffer tank 6a. CO2 is sucked in from the “CO2 bubble” in the upper area of the buffer tank 6a into the connection area V via the second feedback line 11b and / or from the CO2 tank 8a, and the sparkling water is thereby further enriched with CO2. The flow controller vm61 can then be opened and more sparkling water enriched with CO2 can be drawn off.
    The device in the second embodiment can also be used only for dispensing water, as in the case of the first embodiment, by closing the CO2 tap. Thus, the water flows through the buffer tank 6a into the outlet line 4, as in the normal case of a conventional water tap.
    Optionally, a cooling device 22 can be provided to cool the sparkling water in the buffer tank 6a. For example, at least a part of the outlet line 4 between the connection area V and the buffer container 6a can be designed as a pipe coil (not shown), which pipe coil is also cooled with the cooling device 22. The pipe coil extends the path of the sparkling water many times over, so that a stronger cooling effect is achieved than when using a simple pipe and this also favors that the CO2 is better dissolved in the water.
    Fig. 5 shows a circuit diagram of a third embodiment of the invention, namely a system 1a with the first and the second embodiment of the invention Γ, 1. However, two devices of the first or the second embodiment 1, 1 'could also be combined , Only different or new features of the system 1a compared to the first and second embodiment are described below.
    The right block in the figure corresponds to the first embodiment of the device 1 according to the invention and does not differ from this.
    The left block in the figure corresponds to the second embodiment of the device 1 'according to the invention and does not differ from this. In other words, the system 1a comprises two cascaded devices according to the invention with the first and the second embodiment. The second embodiment 1 '(left) can be understood as the first source for providing the first fluid to the second device 1, the first fluid 30 opening into the connection area V via the first inlet line 6 of the second device 1.
    In the left block, the connection area in j60, the associated second input line in 8d, the CO2 container in 8g, the associated first input line in 6b and the associated output line in 8f have been renamed to avoid confusion with the first and second embodiments and to underline that in this case two cascaded devices 1 ', 1 according to the invention are present.
    The system 1 a further comprises a bypass line 8e which connects the first input line 6b of the first device 1 'to the first input line 6 of the second device 1 bypassing a connection area j60 of the first device 1'. This enables a first fluid 26 of the first device 1 ′ to be provided directly to the first input line of the second device (1).
    [0046] The system 1a allows different mixtures of fluids:
    1) Mixture of water 26 from the source 29 with CO2 from the CO2 container 8d: this mixture is provided as explained in connection with FIG. 4 and made accessible via the flow controller vm61, in which case the control element vm40 is closed.
    2) Mixture of water 26 from the source 29 with syrup 27 from the container 8a: this mixture is provided in such a way that the water is made accessible via line 8e bypassing the left block and, via a flow regulator vm51 of the system 1a, directly into the connection area V of the right block is fed and mixed with the syrup 27 as explained in connection with FIGS. 1-3.
    3) Mixing water from source 29 with CO2 from CO2 container 8g and syrup 27 from container 8a: this mixture is provided in such a way that the water first flows into the left block (flow regulator vm51 closed), where it is mixed with CO2 , as already explained in connection with FIG. 4, and is fed via the flow regulator vm61 into the first inlet line 6, where the sparkling water is additionally mixed with syrup 27 from the container 8a.
    4) Provision of water: with system 1a, only water can be released, as in the previous embodiments. This can be done on the one hand as in connection with FIG. 4 by closing the tap vm72 and the tap vm40 and opening the tap vm50 and the flow regulator vm61 or on the other hand by providing the water via line 8e (tap vm50 and flow controller vm51 open, tap vm72, flow controller vm61 and vm40 closed). In this context, reference should be made to the already explained additional function of the devices as an “extended” tap or for CIP cleaning.
    Of course, the sparkling water in system 1a can also be cooled, as already explained. In this context, it is pointed out that additional coolants can be provided for the device 1 ', 1, for example for cooling the container 8a. Furthermore, the lines or a part thereof can be enclosed with insulation in order to protect them from the influence of the outside temperature.
    In all embodiments of the device according to the invention, but in particular in the system la, a controller (not shown), which is preferably coupled to a control element for the user, can be used to change the respective mixture that was selected via the control element to provide. For this purpose, the control closes or opens the respective taps and / or valves for the selected mixture. The controller can also be designed in such a way that it controls the coolants, it being possible in particular to use a timer here to pre-cool the water.
    In summary, the device according to the invention is characterized by a comparatively low complexity, in particular in the case of the first embodiment, and a high degree of flexibility, which is most evident in the system 1 a. Furthermore, it can be operated continuously and is not limited by any dosage elements.
    The device according to the invention is therefore used in its simplest form for mixing a beverage from two fluids. The device is first connected to a tap, which provides water as the first fluid. After opening the tap, water flows into the first inlet line and through the connection area, whereby the second fluid (syrup or CO2) is sucked into the second inlet line and into the connection area and mixes with the water there. The resulting end product (beverage or sparkling water) is continuously discharged through the outlet line until the tap is closed again or partially closed, or until the second fluid from the second source is used up. Because of the simple construction of the device according to the invention, it is possible to use it only by actuating the tap, on the assumption that the device is already connected to the first and the second source.
    As an alternative to the above use, the system 1a according to the invention can be used to mix a drink with the addition of a third fluid (CO2). The system 1a is connected to a faucet which provides water as the first fluid after a CO2 container and a syrup container have been connected as explained above. After opening the respective taps and valves, the tap is opened and the water first flows through the left block of the system, possibly with recirculation, and is enriched with CO2 there. The sparkling water obtained in this way then flows into the right block of the system and is mixed there with the syrup and produces a sparkling drink as the end product.
    Although preferred embodiments of the invention have been described, it is pointed out that the invention can be implemented in other ways within the scope of the following claims. Terms used in the description such as “preferred”, “in particular”, “advantageous”, etc. only relate to optional and exemplary embodiments.
