Description

FIELD OF THE INVENTION

The invention relates to a water bubbler and a system with a water bubbler and an associated bottle.

TECHNICAL BACKGROUND

Water aerators are used to enrich a liquid with a pressurized gas. Water bubblers are particularly often used to carbonate tap water. Water bubblers regularly include a gas reservoir with a compressed gas, a bottle holder for receiving a bottle filled with a liquid, an injection device for gassing the liquid with the pressurized gas and a metering device for metering the pressurized gas with which the liquid is gassed. Water aerators are exemplary from the publication DE 201 01 093 U1 known.

SUMMARY

It is an object of the invention to provide a water bubbler that is particularly easy to use and can be used with bottles that are easy to clean. Another object is to provide a corresponding system with a water bubbler and an easy-to-clean bottle.

The object is achieved according to the invention by a water bubbler for enriching a liquid contained in a bottle with a compressed gas from a gas cylinder. The bubbler has a gassing chamber which is essentially closed in one working position for receiving the bottle and a cylinder compartment for receiving the gas cylinder.

According to one aspect of the invention, the gassing chamber can be fluidly communicated with the cylinder compartment through a pressure relief opening. Any pressure build-up in the fumigation chamber is released particularly quickly through the pressure relief opening.

According to an advantageous aspect, the pressure relief opening can be arranged in a partition between the fumigation chamber and the cylinder compartment. The cylinder compartment offers a comparatively large free volume for receiving a volume flow, by means of which an overpressure in the fumigation chamber is quickly reduced. The pressure in the cylinder compartment rises more slowly than in the gassing chamber due to the throttling action of the pressure relief opening.

According to a further advantageous aspect, the pressure relief opening can be at least partially covered by a splinter catch. In rare cases it can happen that a previously damaged bottle bursts during fumigation. In this case, fragments of the bottle are enclosed in the fumigation chamber. If, however, the fumigation chamber has a pressure relief opening, splinters could pass through the pressure relief opening on a corresponding flight trajectory. The splinter catch is designed as a barrier for the splinters and can be arranged on the flight trajectory in front of, behind and / or in the pressure relief opening. The splinter trap keeps splinters within the fumigation chamber even when there is a pressure relief opening. This greatly simplifies the subsequent cleaning.

The splinter trap can be formed at least partially by a perforated area of the partition. This significantly simplifies production. Alternatively, the splinter trap can comprise a grid or a net.

According to a further advantageous aspect, the fragment trap can comprise a plurality of gas-permeable openings. The gas-permeable openings can each have a maximum cross-sectional width of 15 mm. Cross-sectional width is understood to mean the minimum distance between two sides of the gas-permeable opening. The gas-permeable openings can advantageously each have a cross-sectional length of at most 50 mm. The cross-sectional length denotes the maximum distance between two sides of the gas-permeable opening. According to this aspect, the shape of the gas-permeable openings is advantageously matched to the shape of the splinters in such a way that the splinter catch has a good catching effect but does not restrict the volume flow too much.

The ratio of the cross-sectional length to the cross-sectional width can advantageously be at least 2: 1. The pressure relief opening can further advantageously have a cumulative free cross-sectional area of at least 10 cm 2.

According to a further advantageous aspect, the fumigation chamber can have an access opening for introducing the bottle into the fumigation chamber. The access opening can be formed by a housing part of the water bubbler. The water bubbler can have a closing slide corresponding to the access opening. The closing slide can be designed and set up to essentially completely close the access opening in the working position. The closing slide can also be used as a sliding door be designated. This aspect gives the water bubbler unusual opening kinematics and a high-quality appearance.

According to a further advantageous aspect, the closing slide can be larger than the access opening. In particular, the closing slide can overlap the access opening on all sides in the working position. In other words, the closing slide can protrude all around the edge of the access opening when the gassing chamber is closed. The closing slide can advantageously be arranged on the inside of the access opening of the fumigation chamber. This leads to a self-sealing effect of the closing slide in the event of overpressure in the fumigation chamber.

According to a further advantageous aspect, the closing slide can be displaceable along a movement path. In particular, the movement path can run in a vertical plane. The closing slide can preferably open the access opening by moving upwards. The closing slide can have a curvature in a vertical and / or a horizontal plane and can in particular be displaceable along a correspondingly curved movement path. These aspects relate in particular to the ease of use and the high-quality appearance of the water bubbler.

The closing slide can contain a metallic material, in particular an aluminum alloy or a stainless steel. For example, the closing slide can be made from an aluminum alloy or a stainless steel. Alternatively, the closing slide can be made of a composite, for example a plastic with wire inserts. This aspect concerns in particular the stability of the closing slide.

The water bubbler can have an operating element for enriching the liquid with the compressed gas. According to a further advantageous aspect, the closing slide can cover the control element for an operator when the gassing chamber is open. The operator then has no access to the control element when the fumigation chamber is open. This prevents incorrect operation.

According to a further advantageous aspect, the water bubbler can have an operating element for opening and / or closing the gassing chamber and a locking mechanism for locking the closing slide in the working position. The locking mechanism can be operated by means of the control element.

According to a further advantageous aspect, the water bubbler can have an actuator for automatically opening and / or closing the gassing chamber. The actuator can comprise a spring element and / or a motor. This increases ease of use.

The actuator can advantageously comprise at least one gas pressure spring. If the actuator particularly advantageously comprises two gas pressure springs, the gas pressure springs can be arranged in such a way that spring travel of the two gas pressure springs essentially add up. This enables a particularly large spring travel of the actuator in relation to its length.

According to a further advantageous aspect, the water bubbler can comprise a lid. The cover can be reversibly attachable to a housing part of the water bubbler by closing holding elements for closing the cylinder compartment. In particular, the holding elements can include locking lugs and / or magnets. This aspect increases ease of use, for example.

According to a further advantageous aspect, the cover and the housing part can be designed such that the cover at least partially detaches from the housing part in the event of a sudden increase in pressure in the cylinder compartment. In particular, the cover comes off when the sudden pressure increase in the cylinder compartment is more than 10 bar (advantageously more than 6 bar or more than 3 bar). This aspect leads to a rapid reduction in pressure in the cylinder compartment, so that the water bubbler is not structurally damaged by the excess pressure.

According to a further advantageous aspect, the cover and / or the housing part can also have retaining means. The retaining means can be designed to keep the cover at a distance from the housing part, provided that the cover at least partially detaches from the housing part due to a sudden pressure increase in the cylinder compartment. For example, the restraining device can be a catch hook and / or a safety chain. This way the lid is not lost.

The invention further relates to a system comprising a water bubbler described above and an associated bottle, the bottle being a glass bottle. The bottle is designed to be gassed with a compressed gas in the water bubbler to enrich a liquid contained in the bottle. Glass bottles have a high-quality appearance and are particularly easy to clean.

According to an advantageous aspect, the glass bottle can have a coating and / or Have a cuff. If the bottle bursts, the coating or the cuff can result in no small-scale, freely movable fragments. This aspect makes it easier to clean the water bubbler should a bottle burst.
