Description

The invention relates to a filling device for the low-turbulence filling of an aquarium equipped with a bottom provided with sand, stones and natural aqua-flora and to be filled by means of a hose connected externally on one side to a water source.

Filling devices of the type mentioned are not known in the prior art.

When refilling an aquarium that has been emptied for the purpose of cleaning, the problem regularly arises that the water exiting from a filling hose, when fed into water that has already been introduced into the aquarium during the same filling process, has such a high flow rate that the water that is already flowing into the aquarium is swirled Aquarium introduced water takes place and thus a churning up of particles from the bottom area of the aquarium is regularly recorded, with the result that the water in the aquarium becomes cloudy and opaque during the filling process.

The pamphlet DE 19 81 028 U discloses a water outlet for aguarial filters made of plastic or other material, in which the outflowing filter water is sprayed circularly or semicircularly onto the water surface of the aquarium, the outflow, for example, from a round or semicircular or ovally curved or differently shaped cylindrical or angular tube with a There is water inlet, with any outflow holes made in the pipe.

The pamphlet DE 10 2004 042 391 A1 discloses a device for introducing a gaseous medium into a liquid medium, wherein a mixing chamber is provided which has a plurality of side-by-side channels which are separated from one another by partition walls, the channels each having an inlet opening and an outlet opening, with a first surface the mixing chamber, which has the inlet openings, is located in a predetermined position relative to a liquid supply device, and wherein the first surface of the mixing chamber is located in the gaseous medium and a second surface of the mixing chamber, which has the outlet openings, in the liquid medium or outside the liquid Medium is located.

From the pamphlet U.S. 4,788,938 A a device is known which divides an aquarium into an upper terrarium part and a lower aquarium part, comprising a buoyant structure which is inserted into the aquarium and has outer peripheral walls which are in slidable engagement with a plurality of inner side walls of the aquarium, the outer peripheral walls of the floatable structure formed with sufficient height and at the same time engaging in sufficient numbers with the inner side walls of the aquarium to prevent the buoyant structure from tilting or moving in a lateral direction while allowing the buoyant structure to move vertically in response to fluctuations in the water level.

The object of the invention is to create a filling device with the help of which it is ensured that the water already present in the aquarium remains clear and transparent, in particular during the filling process.

According to the invention, this object is achieved by means of a filling device having the features of claim 1.

Preferred embodiments of the invention are the subject matter of the dependent claims, the elements of which act in the sense of a further improvement of the approach to the solution of the object on which the invention is based.

In the filling device according to the invention, with the help of the combination of features, a concave / convex shaped floating body is provided that can be placed below the open end of the hose in order to collect water emerging from the hose in a central area and at least flow over laminar lines By guiding the peripheral areas of its surface that are convexly curved towards the water surface, the flow velocity of the water exiting from a filling hose is reduced to such an extent in the peripheral areas of the floating body when it is fed into water that has already been introduced into the aquarium during the same filling process of the water that has already been introduced into the aquarium is largely avoided, thus preventing particles from being churned up from the bottom area of the aquarium, with the result that the water in the aquarium is clear and clear even during the filling process remains valid.

According to a first preferred embodiment of the filling device according to the invention, it is provided that the floating body is designed to be rotationally symmetrical and the diameter of the floating body is large enough that the water flowing into the interior of the aquarium via its peripheral areas does not exceed a predetermined flow rate.

The diameter of the rotationally symmetrical floating body is included preferably dimensioned so large that the water flowing into the interior of the aquarium via its peripheral areas maintains its laminar flow when it is mixed with water already filled in the aquarium while avoiding turbulence.

In particular, the central area of the floating body with its surface remote from the water already filled in the aquarium, which is provided for receiving water emerging from the hose, is preferably designed to be concave.

According to a further preferred embodiment of the filling device according to the invention, a transition area of the floating body provided between the central area and the peripheral areas is horizontally planar.

According to a preferred embodiment of the filling device according to the invention which is an alternative to the above embodiment, a transition area of the floating body provided between the central area and the peripheral areas is designed in a horizontally undulating concave / convex manner. Due to a longer distance compared to the above embodiment and the associated increased friction when overflowing the surface of the floating body, a particularly effective reduction in the flow speed of the water flowing in is ensured.

In practice, a diameter of the rotationally symmetrical floating body of between 10 cm and 30 cm, and in particular about 20 cm, has proven effective.

According to an important preferred embodiment of the filling device according to the invention, the central area of the floating body is designed as part of a hollow sphere, which preferably has a greater depth than the peripheral areas.

The material of the float is not critical. The condition is that it is robust and buoyant, i.e. lighter than water. Styrofoam, in particular, has proven itself as a material.

• 2 eine in 1 dargestellte bevorzugte Ausführungsform der erfindungsgemäßen Befüll-Vorrichtung in einer Ansicht von oben.

The filling device according to the invention is explained below with reference to a preferred embodiment, which is shown in the figures of the drawing. Show in it:

• 1 a preferred embodiment of the filling device according to the invention in a view obliquely from above;
• 2 one in 1 illustrated preferred embodiment of the filling device according to the invention in a view from above.

The ones in the 1 and 2 illustrated filling device according to the invention 100 is intended for low-turbulence filling of an aquarium equipped with a bottom provided with sand, stones and natural aqua-flora and to be filled by means of a hose that is externally connected to a water source on one side.

For this purpose, a concave / convex shape is provided with a floating body 110 provided, which can be placed below the open end of the hose, in order to prevent water escaping from the hose in a central area 112 to be collected and flowing in a laminar manner, at least over the water surface 111 towards convexly curved peripheral areas 114 its surface 111 to direct.

The diameter of the rotationally symmetrical floating body 110 is sized so large that it covers its peripheral areas 114 Water flowing into the interior of the aquarium does not exceed a specified flow velocity.

The diameter of the rotationally symmetrical floating body 110 is dimensioned so large that it covers its peripheral areas 114 Water flowing into the interior of the aquarium, when mixed with water already filled in the aquarium, maintains its laminar flow while avoiding turbulence and is dimensioned to 20 cm in the embodiment shown.

The central area 112 of the float 110 is with its surface distant from the water already filled in the aquarium 111 designed to receive water emerging from the hose in a concave shape, with a between the central area 112 and the peripheral areas 114 intended transition area 113 of the float 110 horizontally undulating concave / convex.

The central area 112 of the float 110 is designed as part of a hollow sphere and has a greater depth than the peripheral areas 114 of the float made of styrofoam 110 .

The exemplary embodiment of the invention explained above only serves the purpose of a better understanding of the teaching according to the invention given by the claims, which as such is not restricted by the exemplary embodiment.
