CS9001929A2 - Inlet cover for fresh water, if need be, chemical compounds in swimming pools - Google Patents

Description

1 i ιίί.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inlet lid for fresh water, or a chemical in a swimming pool, which is fixed above a canal channel provided in the bottom of the pool. For existing pools, fresh water and chemicals needed for water treatment are brought to the bottom and fed back into the water treatment plant by overflowing the pool water into the overflow groove. It is thus ensured that the water will be completely renewed at specified times.

In addition, the distribution of freshly flowing water during the operation of the pool should be carried out in as short a time as possible. The aim of this rapid distribution is to make the chemically-enriched new water dispersed in the pool and thus allow for continuous disinfection.

The known inlet lid construction is designed so that a fresh water inlet channel, which is located in the bottom of the pool, is covered over its entire length by a cover plate. This cover sheet is provided with openings over which a cap is attached which is provided with side openings through which water flows.

This construction has the disadvantage that the lids protrude from the bottom of the pool so that the bottom cleaning devices are prevented from working; these can then hang on these protrusions, possibly damaging them. 2

Therefore, it has been attempted to provide a lid for the bottom which would obviate these drawbacks and which could be easily made. This has been achieved in accordance with the invention in that the inlet lids are arranged in the bottom level in a row, they are located in recesses having otyors located between the inlet plug surface provided at the bottom level and the corresponding recess and forming the guide 'area for mediaj flowing out of holes. As a result, floor cleaning devices may not avoid projections.

The possibility of injury to bathers is excluded.

These lids have no dead spaces since they are in one piece and are not assembled as existing multi-part lids.

They are therefore also easy to manufacture and, due to their negligible dead spaces, there is little current loss. Furthermore, the risk of trapping in dead spaces is prevented.

A very suitable embodiment according to the invention can be carried out in such a way that the recess is provided in a longitudinal cross-section with a side of the outer side of the outer side of the surface. The recess forms a guide surface for the medium flowing out of the opening.

This construction is easy to manufacture and, depending on the size of the recess and opening, the range, amount and flow angle can be adjusted. These gating lids can also be formed in such a way that the openings are provided in the short side below the bottom level and in the area between the bottom level and the opening, the edge of the lid, directed towards the opening, is curved. ........_ y *

This construction is advantageous in that the edge side facing the opening reverses the current and is then thrown over the long side of the recess. As a result, the swiveling and reach of the projecting beam can be controlled even better. A further effect of this method is that by reversing the current, another protection against injury is obtained.

According to a further embodiment, it is also possible that the depressions with the openings are always symmetrically arranged in pairs to the longitudinal axis of the lid, the longitudinal axis of the depression being parallel to the longitudinal axis of the lid and below which the supply channel is located. the recess lies on a circular arc, the center of the circular arc being on. The longitudinal axis of the lid, according to the geometrical positioning of the lid in the lid, makes it adaptable to the necessary direction of flow and the resulting favorable mixing.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a lid according to the invention, which is provided on the inlet channel; FIG. 2 is a plan view of such a lid;

The inlet lid 1 is fastened by screws (not shown) to the inlet duct 2 and is laterally sealed with sealing strips 3. The recesses 4 are provided with openings 2 in their short side. hole. This turns the current and throws it against. Long Side 8 Depth 4. Depending on the size of the aperture and the recess, the amount, spacing and angle can be varied. <? J ·
