Definitions

• Ventilation device for a liquid-filled pool
• the invention relates to a ventilation device for a liquid-filled basin, with an air supply line which opens into an air distributor, to which distribution lines for the air supply into the basin are connected, the passage gaps between the distribution lines being arranged in the vertical direction and the distribution lines at their opposite ends are fastened to a rear cross member and the distributor and the rear cross member are connected to one another by connecting members so that they form a frame for the ventilation device.
• Aeration devices for liquid-filled pools have distribution lines, for example in the form of perforated hoses, through which the air is supplied to the pools.
• the distribution lines are fastened in the frame of the ventilation device and run side by side over the bottom of the basin.
• the frame is formed by a horizontally guided air distributor, into which an air supply duct opens, the rear cross member and by longitudinal connecting members fastened on one side to the air distributor and on the opposite side to the rear cross member.
• the inner space of the air distributor in the form of the cylindrical tube is connected to the inner space of the individual distribution lines.
• the distribution lines are attached to the opposite end on the rear cross member.
• the benefit lines are perforated over their entire length. This leads to a relatively intensive ventilation of the liquid not only above the ventilation device, but also in the area of the pelvic floor if the distribution lines are arranged at a certain height above the floor. This is ensured by foot frames that are attached to the frame of the device.
• the frame is formed by two bands made of plastic material and welded together.
• the two bands are welded to each other, apart from the parts provided with the perforation, forming ventilation pipes and the pipe parts for guiding the suspension element, which at the same time can serve as a load on the device.
• Aeration devices are used pull cables for lowering and lifting the device in or out of the pool. With the help of the pull cables, the ventilation devices are pressed to the bottom of the pool by means of the foot frames, the guides of the pull cables contributing to the stabilization of the ventilation devices. These measures only contribute to stabilization in one direction, while they are relatively ineffective in the other direction, which can be the water flow direction.
• the aim of the invention is a ventilation device with a high intensity of ventilation not only in the pool with standing water, but also with flowing water, whereby it could be used for the various sizes and ventilation capacities and at the same time would have made it possible to stabilize the pool floor in the flowing liquid .

• the air distributor 2 and the rear cross member 3 are in the form of the cylindrical tube and their inner spaces are connected by means of the distribution lines 4.
