Abstract

The method uses a gaseous medium, pref. air, which is directed in an inclined injector (2) via a hose (1.1) in the region of the injector's delivery tube. The ejection of the air draws out the fluid and any impurities from the pool floor (7).A rebound surface (2.4) modulates any turbulence cased and the velocity of the flow is regulated by acceleration nozzles (2.5) any impurities are fed to a mouthpiece (2.3) on the water surface (5) and are removed from the water by a filter (3).

Description

The invention relates to a method and the associated Device for cleaning liquid pools, preferably Swimming pools and similarly designed liquid containers nissen with simultaneous removal of dirt in the floor and surface area.

Devices and devices for keeping swimming pools clean are known in a variety of designs. At the Water surfaces with filter systems are the most common cleaned. Clean water is fed into the pool, in an overflow, the contaminants are drained off and mostly also filtered out. These plants are true effective, but also technically and financially complex and require a relative even with temporary operation high energy consumption.

Another type are so-called water ridges. Doing so Kind of floating comb pulled over the water surface, to remove the dirt. With this solution a parallelism of the two opposite pool edges fundamentally presupposed to lead accordingly to guarantee. This also has a disadvantage Solution of the relatively high technical effort for train and Leadership mechanisms.

For cleaning the bathroom floors, devices according to the analog principle of the vacuum cleaner used.

Basically, however, is done with known practical ones Devices separate the cleaning process from Water surface and pool bottom.

The object of the invention is a cleaning device to create the same time for pelvic floors and liquid surfaces works, low technical Effort required for different pool shapes and -types can be used and with low energy consumption can work continuously.

The plant is not only intended for the removal of organic Soiling in bathing pools, but also in their principle for technical baths and containers can in which a continuous floor and / or Surface suction is desired.

According to the invention the object is achieved in that an inclined injector in the lower part of his Delivery tube over a hose a gaseous medium is fed. The medium is preferred wise of air. However, oxygen and inert gases are also available or other media that is lighter than the associated Liquid are conceivable. The gaseous medium draws during its buoyancy liquid and impurities of the pelvic floor with. The medium modulates on the impact surface turbulence. About accelerator nozzles, their Openings are continuously narrowing in the direction of flow the flow is excited. A mouthpiece takes out impurities the surface of the water, and the Liquid separated from the contaminants.

According to the invention, a Device used, the main components of which are a pump, has an injector and a filter. The pump is connected to the injector via a hose.

The injector consists of a suction foot, a delivery pipe and a mouthpiece. The conveyor pipe has on its Inside a variety of baffles, preferably are designed as knobs, rings and / or teeth. However, other forms of inhibition thresholds are also possible.  

In addition, accelerators can be located inside the conveyor tube nozzles can be arranged, the funnel-like training exhibit. The openings of the accelerator nozzles are in Flow direction constantly reduced.

The conveyor pipe points to the bottom of the basin Inclination angle of preferably 30 °. . . 40 ° on. The injector has a mouthpiece on its upper side, which is located in the area of the water surface and the Contaminates the surface. The exit end of the mouthpiece is with the collecting bowl of the filter firmly connected. The collecting bowl has one in the middle Drain pipe in which a fine filter is inserted. also is the drain pipe from a sieve-like cover covers.

The filter is basically within the basin in height arranged floating on the water surface. It exists however, also the possibility of bathing pools as well as technical baths, the filter outside the basin to arrange.

Using an exemplary embodiment, the invention is intended are explained in more detail.

The associated drawing shows in

Fig. 1 is a schematic diagram of the solution according Invention,

Fig. 2 shows the filter 3 as a detail from the illustration. Fig. 1

Fig. 3 shows the injector 2 as a detail from the Dar position. Fig. 1.

The device consists of a pump 1 , an injector 2 and a filter 3 . For a water surface of 20 m², the pump output is 3. . . 5 watts sufficient.

The pump 1 is connected to the injector 2 via an air hose 1.1 . The injector 2 consists of a suction foot 2.1 , a delivery pipe 2.2 and a mouthpiece 2.3 . The inside of the delivery pipe 2.2 has baffle surfaces 2.4 which are designed as knobs, rings and / or teeth. In addition, 2.2 acceleration nozzles are arranged in the conveyor tube, the openings of which are continuously reduced in the direction of flow 4 .

The mouthpiece 2.3 is placed over the last acceleration nozzle 2.5 arranged in the flow direction 4 . Its inlet opening 2.31 is basically at the level of the water surface 5 . The outlet end 2.32 of the mouthpiece 2.3 is embedded in a collecting bowl 3.1 of the filter 3 . A drain pipe 3.2 with a fine filter 3.3 is arranged centrally in the collecting bowl 3.1 . Above the drain pipe 3.2 there is a sieve-like cover 3.4 , which offers unimpeded flow and resistance to contamination. In the area of the squeegee 2.1 and the collecting bowl 3.1 , detents 6 can be arranged for the safe positioning of the device. The delivery pipe 2.2 basically has an inclination angle α of 30 ° with respect to the pool floor 7 . . . 45 ° on.

  A procedure with the following results from this structure Mode of action:

The pump 1 continuously presses air into the delivery pipe 2.2 via a hose 1.1 .

The air bubbles which move obliquely upward in the direction of flow 4 attract water and dirt particles from the pool floor 7 via the suction foot 2.1 and at the same time bring about a floor cleaning. The upward-moving air bubbles continuously collide against the baffles 2.4 due to the inclined α 2.2 delivery tube 2.2 , are thereby braked in their buoyancy and at the same time generate turbulence to increase the flow rate.

In addition, the air is given additional potential by the laws of buoyancy in the accelerator nozzles 2.5 .

In the area of the mouthpiece 2.3 , the flow rate of the liquid-air mixture has reached such an intensity that, according to the injector principle, the contamination of the water surface 5 is sucked in through the mouthpiece 2.3 and reaches the collecting bowl 3.1 . The radial arrangement of the mouthpiece 2.3 in the collecting bowl 3.1 creates a natural vortex which further increases the suction effect.

The drain pipe 3.2 is arranged in the collecting bowl 3.1 flush with the water surface 5 and enables unimpeded return of the cleaned water to the pool. Before the water is returned, the dirt is retained by the sieve-like cover 3.4 . The fine filter 3.3 located in the drain pipe retains fine dirt and at the same time prevents algae formation in the water.
