Description

The present invention relates to a device and a method for producing a carbonated liquid. The device and the method serve in particular to provide the carbonated liquid via a fitting (or a sanitary fitting).

Devices and methods for producing a carbonated liquid with a carbonizer are known, through which carbon dioxide (CO2) can be added to a liquid, in particular water. The carbonizer allows the CO2 to be pressed into the liquid, particularly under high pressure. For this purpose, the carbonizer can be connected to a CO2 container in the form of a CO2 cylinder, in which the CO2 is stored for the carbonator.

There are currently various table-top soda makers or under-table devices with cooling and carbonation functions. Soda makers have the disadvantage that they take up additional space on the work surface. In addition, these devices usually do not look high quality. That's why many users don't want to have them on the worktop in the kitchen.

Under-sink devices with built-in cooling and carbonation units have the disadvantage that they are expensive to purchase. You also cool down the water, which leads to additional energy costs. Many users do not like water that has been cooled down, but prefer a drinking temperature of more than 15 degrees Celsius, i.e. a temperature e.g. B. drinking water that can be taken directly from a water pipe.

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 device for producing a carbonated liquid with which the carbonated liquid can be produced at lower costs. The device should be designed to save as much space as possible.

These tasks are solved with a device according to the features of the independent patent claim. Further advantageous embodiments of the invention are specified in the dependent claims. It should be noted that the features listed individually in the dependent patent claims can be combined with one another in any technologically sensible manner and define further embodiments of the invention. In addition, the features specified in the patent claims are specified and explained in more detail in the description, with further preferred embodiments of the invention being presented.

A device for producing a carbonated liquid is proposed, comprising at least a drinking water supply line, a CO2 container and a fitting. The fitting has at least a first outlet for drinking water supplied via the drinking water supply line and a second outlet for CO2 supplied via a pressure line from the CO container.

The fitting is in the manner of a basically well-known sanitary fitting, such as. B. is used in kitchens. However, with the proposed fitting, a container can first be filled with drinking water and then carbonated using the fitting. The carbonization does not take place in an under-sink device, but rather takes place via the fitting in the manner of a table-top soda maker.

This means that lower purchase costs can be achieved, particularly compared to the known under-table devices, and the otherwise required space on a work surface is saved compared to table-top soda makers.

The proposed device comprises a fitting that can be arranged or is arranged, for example, on a washbasin or sink. Using the device or fitting, the carbonated liquid can be produced in a container that can be filled via the fitting. The container is in particular a bottle, a glass or a cup.

The drinking water supply line is intended in particular only for cold water, in particular filtered cold water, or alternatively for mixed water or even hot water. Alternatively, in addition to the drinking water supply line and the pressure line, the fitting can also have a fluid supply line for another liquid, such as cold water, warm water, mixed water and/or hot water (for example with a hot water temperature of 95 degrees Celsius to 100 degrees Celsius).

The fitting can be arranged in particular in a kitchen and/or attached to a mounting surface, such as a worktop in a kitchen. The CO2 container can in particular be arranged below the mounting surface of the fitting, for example in a cabinet, and/or can be connected to the fitting via the pressure line, for example in the manner of a flexible hose.

The device or the drinking water supply line is in particular connected to a liquid source, for example a water pipe connected to a public water supply network bindable. Using the device, CO2 can be added to the drinking water. This means in particular that the CO2 can be supplied to the drinking water arranged in a container, in particular under high pressure (e.g. between 4 and 7 bar), so that the CO2 dissolves in the drinking water in particular and/or at least partially with the drinking water reacts to carbonic acid.

The CO2 container is in particular interchangeably connected to the pressure line. The CO2 is stored in the CO2 container, in particular under pressure, in a storage chamber. For this purpose, the CO2 container is designed in particular in the manner of a CO2 cylinder. Furthermore, the CO2 container in particular has a storage capacity for CO2 of less than 2 kg. In a full CO2 container, the CO2 has in particular a pressure of 55 to 60 bar, preferably (approximately) 57 bar, at 20 degrees Celsius.

In particular, the device comprises at least one actuating element through which CO2 can be switchably removed from the pressure line via the second outlet. In particular, the actuating element is designed separately, i.e. H. The carbonization can be carried out independently by a user. In particular, a further actuating element can be provided, via which an exit of the drinking water from the first outlet can be controlled or regulated.

The at least one actuating element is in particular arranged directly on the fitting.

In particular, the fitting has a connection for the gas-tight connection of a container. The container is designed to accommodate the drinking water supplied via the first outlet and the CO2 supplied via the second outlet and has a connection geometry that matches the connection.

The container should e.g. B. can withstand the pressures usually present during carbonization (maximum pressure is in particular between 4 and 7 bar) without bursting. The connection geometry should e.g. B. enable a secure and gas-tight connection of the container to the connection, e.g. B. via a threaded connection.

In particular, the container has an adapter via which the container can be connected to the connection. The adapter has at least one lance, which can be connected to the second outlet via the connection and extends through the adapter into a container volume of the container at least to such an extent that an outlet opening of the lance is within a drinking water volume of the container completely filled with drinking water located. The outlet opening of the lance should therefore extend in particular to below the liquid level of the drinking water present in the container. If possible, the lance should extend all the way to the bottom of the container so that even small volumes of drinking water can be safely carbonated.

The adapter can first be connected to the container or to the fitting, with the container then subsequently being connected to the adapter to the fitting or the container to the adapter arranged on the fitting.

Alternatively, the lance is arranged directly on the fitting, so that the container can be arranged directly (and if necessary without an adapter) on the connection. However, it should be noted that the lance (especially the one with a long length) is rather a hindrance in normal use of the fitting (i.e. not just when carbonizing).

The adapter can be used to provide a solution that can be used independently of the container and the fitting (i.e. the fitting and the container can be designed without the adapter or the lance).

In particular, the device has at least one fluid supply line and the fitting has a third outlet for the fluid supplied via the fluid line. In addition to the drinking water supply line and the pressure line, the fitting can also have the fluid supply line for another liquid, such as cold water, warm water, mixed water and / or hot water (for example with a hot water temperature of 95 degrees Celsius to 100 degrees Celsius).

In particular, the fitting has a connection for the gas-tight connection of a container, the container having a connection geometry that matches the connection. Through the connection, the first outlet, the second outlet and the third outlet can be fluidly connected to a container volume of the container. This means that the container can e.g. B. be filled with a liquid via the first outlet and/or the third outlet.

Alternatively, only the first outlet and the second outlet are fluidly connected to a container volume of the container through the connection. In particular, the third outlet is then arranged outside the connection. This allows e.g. B. the third outlet can be used regardless of the container or the filling of the container.

• • an der Armatur in der Druckleitung oder
• • an einem Adapter, der den Behälter mit der Armatur verbindet, angeordnet ist.

In particular, the fitting has a connection for the gas-tight connection of a container, wherein a safety valve

• • on the fitting in the pressure line or
• • Is arranged on an adapter that connects the container to the fitting.

The safety valve can be used to prevent excess pressure in the container to be filled or in the pressure line.

The safety valve is arranged in particular between the CO2 container and the second outlet. The safety valve can also be arranged in the container or on the adapter.

In particular, a pressure reducer is arranged in the pressure line so that any pressure present in the CO2 container is not passed on to the pressure line or to the container. The pressure reducer is arranged in particular between the CO2 container and the safety valve.

A method for producing a carbonated liquid using the device described is proposed. The device includes at least a drinking water supply line, a CO2 container and a fitting.

The fitting in particular has at least a first outlet for drinking water supplied via the drinking water supply line and a second outlet for CO2 supplied via a pressure line from the CO container.

1. a) connecting a container to the connection;
2. b) carbonating the drinking water (or a liquid arranged therein) arranged in the container by supplying CO2 into the container via the second outlet.

In particular, before step b), and possibly before or after step a), the container is filled with a liquid (which, for example, does not have to be provided via the fitting). In particular, before step b) and after step a), the container is filled with drinking water via the first outlet or via a third outlet.

The comments on the method apply in particular to the device and vice versa.
