Description

The present invention relates to a dispensing device with which a carbonated liquid can be dispensed into a container.

Tap devices are known, for example, the type of sanitary fittings that regularly serve the need-based provision of water at a tapping point, a sink, sink, bathtub and / or showers. For this purpose, the tapping devices in particular cold water with a cold water temperature and hot water with a hot water temperature is supplied. The cold water and hot water are mixed in particular with a mixing device of the dispensing devices, for example in the manner of a mixing valve or a thermostatic mixing cartridge, to a mixed water having a desired mixed water temperature. The cold water temperature is in particular at most 25 ° C (Celsius), preferably 1 ° C to 25 ° C, more preferably 5 ° C to 20 ° C and / or the hot water temperature in particular at most 90 ° C, preferably 25 ° C to 90 ° C, more preferably 55 ° C to 65 ° C. Furthermore, dispensing devices are known by means of which the cold water, the hot water and / or the mixed water carbon dioxide (CO2) is zusetzbar. The addition of CO2 thus produces carbonated table water from tap water. Furthermore, the cold water, the hot water and / or the mixed water flavors can be admixed so that different carbonated liquids can be provided with the dispensing devices. A disadvantage of the known dispensing devices, however, is that a CO2 concentration in the carbonized liquids after the pin is not high enough and / or a jet pattern of the carbonated liquid does not correspond to a desired quality after emerging from an outlet opening of the dispensing devices.

The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to provide a dispensing device with which a carbonated liquid with a high concentration of CO2 and with an attractive spray pattern is zapfbar.

This object is achieved with a dispensing device according to the features of the independent claim. Further advantageous embodiments of the dispensing device are specified in the dependent claims. It should be noted that the features listed individually in the dependent claims can be combined with each other in any technologically meaningful manner and define further embodiments of the invention. In addition, the features specified in the claims are specified and explained in more detail in the description, wherein further preferred embodiments of the invention are shown.

• ein Armaturengehäuse mit zumindest einer ersten Leitung für eine karbonisierte Flüssigkeit,
• einen Düseneinsatz, der in der zumindest einen ersten Leitung angeordnet ist, wobei der Düseneinsatz einen Leitkanal mit einem ersten Durchmesser aufweist, mit der die karbonisierte Flüssigkeit zu einer Prallwand des Düseneinsatzes führbar ist, sodass die karbonisierte Flüssigkeit durch die Prallwand verwirbelbar ist,
• ein Expansionsraum, der stromabwärts des Düseneinsatzes angeordnet ist, wobei der Expansionsraum einen zweiten Durchmesser aufweist, der größer ist als der erste Durchmesser des Leitkanals, und
• eine Auslauföffnung, die stromabwärts des Expansionsraums angeordnet ist und durch die die verwirbelte karbonisierte Flüssigkeit aus der Zapfvorrichtung austreten kann.

Contributing to this is a dispensing device which has at least the following components:

• a fitting housing with at least a first conduit for a carbonated liquid,
• a nozzle insert disposed in the at least one first conduit, the nozzle insert having a first diameter passageway for guiding the carbonated liquid to a baffle of the nozzle insert such that the carbonated liquid is fluidizable through the baffle,
• an expansion space disposed downstream of the nozzle insert, the expansion space having a second diameter greater than the first diameter of the guide channel, and
• an outlet opening disposed downstream of the expansion space and through which the fluidized carbonated liquid can exit the dispensing device.

The dispensing devices may be designed, for example, in the manner of a sanitary fitting and / or serves, in particular, for the demand-oriented provision of a mixed water at a dispensing point, a sink, a washbasin, a shower and / or a bathtub. Furthermore, a carbonated liquid can be tapped with the dispensing device. The carbonated liquid is a carbon dioxide-containing liquid. For this purpose, the dispensing device can be connected to a source of the carbonated liquid and / or by means of the dispensing device is a liquid, in particular tap water, for example in the form of a cold water, hot water and / or mixed water, carbon dioxide (CO2) zusetzbar. The dispensing device has a fitting housing that at least partially made of plastic and / or metal, such as brass, may exist. By means of the fitting housing, the dispensing device, in particular on a support, for example in the manner of a countertop, table top or wall, fastened. The fitting housing has at least one first line for a carbonated liquid, by means of which the carbonated liquid can be conducted through the fitting housing and / or by means of which the carbonated liquid can be guided in the direction of an outlet opening of the tapping device. Furthermore, the fitting housing can have at least one second line for a further liquid, such as, for example, cold water, hot water and / or mixed water, by means of which the liquid can be conducted through the fitting housing and / or by means of which the liquid can be guided in the direction of the outlet opening of the tapping device.

In the at least one first line, a nozzle insert is arranged. The nozzle insert is, in particular, a separate component that can be at least partially tubular and / or made of plastic. The nozzle insert has a guide channel with a first diameter, with which the carbonated liquid can be guided to a baffle wall of the nozzle insert. If a first cross-sectional area (orthogonal to a longitudinal axis of the guide channel and / or to a flow direction of the carbonated liquid in the guide channel) of the guide channel is not circular, the first diameter is in particular an average diameter of the cross-sectional area of the guide channel. Through the guide channel, the carbonated liquid is particularly compressible and / or accelerated. The guide channel may be formed, for example, in the manner of a guide bore. Furthermore, the guide channel may have a straight course and / or without flow obstacles for the carbonized Be formed liquid. The guide channel is preferably flowed through by the carbonized liquid with a laminar flow. In addition, a longitudinal axis of the guide channel can extend parallel and / or coaxially to a longitudinal axis of the nozzle insert. The guide channel preferably extends from a first longitudinal end of the nozzle insert to the baffle, wherein the baffle is formed in particular at a second longitudinal end of the nozzle insert. The baffle can also have an area that is larger than a cross-sectional area of the guide channel. The surface of the baffle can thus completely cover the cross-sectional area of the guide channel (in particular in the direction of the longitudinal axis of the guide channel). The carbonated liquid bounces (in the flow direction of the carbonized liquid) at the end of the guide channel on the baffle, so that it is swirled by the baffle. Due to the impact of the carbonized liquid on the baffle wall, a flow direction of the carbonated liquid is deflected in particular by at least 45 °, preferably (substantially) 90 ° and / or in particular in different directions. The carbonized liquid preferably flows out of the nozzle insert after impacting the baffle wall through at least one radial outlet opening.

Downstream of the nozzle insert, an expansion space for the carbonated liquid is formed. In particular, the expansion space has a second diameter which is greater than the first diameter of the guide channel and / or greater than the third diameter of the at least one first line. If a second cross-sectional area of the expansion space (orthogonal to a longitudinal axis of the expansion space and / or to a flow direction of the carbonated liquid in the expansion space) is not circular, the second diameter is, in particular, an average diameter of the cross-sectional area of the expansion space. If a third cross-sectional area (orthogonal to a longitudinal axis of the at least one first line and / or to a flow direction of the carbonated liquid in the at least one first line) of the at least one first line is not circular, the third diameter is in particular an average one Diameter of the cross-sectional area of the at least one first conduit. In particular, the second diameter of the expansion space can be at least 50% larger, preferably at least 100% larger, particularly preferably at least 200% larger than the first diameter of the guide channel and / or as the third diameter of the at least one first line. In particular, the carbonized liquid can expand in the expansion space, so that the spray pattern of the carbonated liquid emerging from the dispensing device is further improved. Furthermore, the baffle wall (with respect to a cross-sectional area of the expansion space) is preferably positioned (substantially) centrally in the expansion space. In addition, the at least one outlet opening of the nozzle insert (in particular in a radial direction of the nozzle insert) may preferably be arranged in a manner spaced apart from a boundary wall of the expansion space.

Downstream of the expansion space, the carbonated liquid flows to an outlet opening of the dispensing device, through which the carbonated liquid can flow out of the dispensing device. The impact of the carbonated liquid on the baffle creates a pearl effect, so that when the carbonated liquid leaves the outlet, an attractive spray pattern is created.

The baffle can be aligned at least partially orthogonal to a longitudinal axis of the guide channel. Preferably, the baffle wall is (substantially) planar and / or runs completely orthogonal to the longitudinal axis of the guide channel.

In addition, the baffle can be connected via at least one web with the nozzle insert. The at least one web extends at the second longitudinal end of the nozzle insert, preferably in the direction of the longitudinal axis of the nozzle insert. The nozzle insert preferably has two webs, which are arranged offset by 180 ° to each other about the longitudinal axis of the nozzle insert. In a circumferential direction of the nozzle insert, the two webs preferably define two (radial) outlet openings of the nozzle insert.

The nozzle insert may have at least one outlet opening for the carbonated liquid between the guide channel and the baffle wall. As a result of the at least one outlet opening, the carbonated liquid can preferably emerge from the nozzle insert in a radial direction of the nozzle insert.

The first diameter of the guide channel may be smaller than a third diameter of the at least one first line. In particular, the first diameter of the guide channel is smaller than the third diameter of the at least one first line immediately upstream of the nozzle insert. As a result, an acceleration of the carbonated liquid in the guide channel can be generated, so that it bounces on the baffle with a particularly high flow velocity.

The nozzle insert may have an inlet cone through which the carbonated liquid enters the guide channel. The inlet cone is, in particular, a surface of revolution which is formed by a (preferably convex) curve rotating about the longitudinal axis of the nozzle insert. The inlet cone is located in particular at an opening of the guide channel relative to the baffle wall.

The nozzle insert may have a groove for a seal on a circumferential surface. The groove is in particular annular, so that in this a seal in the manner of an O-ring can be arranged.

The nozzle insert can be used through the outlet opening in a receiving space in the valve body. This means, in particular, that the nozzle insert during assembly of the dispensing device can be inserted through the outlet opening into the receiving space, without having to be provided for the nozzle insert more openings in the valve body.

The receiving space may be formed in an adapter. The adapter is in particular a separate component that is preferably at least partially sleeve-shaped. In particular, the adapter has an inner diameter that substantially corresponds to an outer diameter of the nozzle insert. In addition, a hose for supplying the carbonated liquid can in particular be connectable to the adapter. Furthermore, the adapter can be attached to and / or in the fitting housing.

The guide channel, the baffle and at least one outlet opening can be integrally formed by the nozzle insert.

According to a further aspect of the invention, a use of a nozzle insert with a guide channel, a baffle wall and at least one outlet opening for guiding a carbonated liquid in a dispensing device is also proposed. For further details of the nozzle insert, reference is made to the description of the dispensing device.
