Description

 DEVICE FOR HEATING THE WATER OF A SWIMMING POOL, BY TERRACE EXPOSED TO SOLAR RADIATION.

The heating of a pool is often considered a luxury inaccessible by many pond owners. Yet, it is an indisputable way to make your pool profitable. A heated swimming pool allows to prolong its bathing and sometimes to bathe in gloomy weather at the beginning of the spring or the end of the summer or to bathe the night and a big part of the year.

There are today several devices for heating the water of a pool, some of which are more efficient, faster, more economical than others but all represent an investment and constraints due to the assembly and interview. The most common means today is the heat pump. It remains the most versatile and often very powerful and economical. It remains the favorite of pool owners because it can maintain the water temperature when it is already high and for example at 28 ° C but the temperature rise of the water in the basin is very slow. This heating mode is rather expensive to install and requires a significant investment. It can be used for both outdoor ponds and covered ponds.

Many pools of private pools are now equipped with heat exchanger heating some of which use hot water from the heating network of the house to heat the pool water. The water is then heated by the domestic boiler (oil or gas). The consumption of this heating system depends on the type of boiler and the rise in water temperature the power of it. This mode of heating is certainly effective and fast but expensive and requires significant installation costs if the installation was not planned during the construction of the house. In addition, the pool must obviously be as close as possible to the house or inside the building itself.

Solar heating remains the most environmentally friendly way. It is ideal when the pool is outside or in a covered building but in a sunny area and when the owner simply wants to increase his swimming comfort and extend the season of his swimming pool. It is very suitable if it is simply looking for water a little warmer than the water at room temperature during the season. It is indeed a heating 100% natural, more expensive to buy but which costs nothing in energy. It does not provide a rapid rise in water temperature but can effectively maintain a temperature already reached water basin. By this means, we simply exploit the energy of the sun through solar panels. The pool water is propelled by one or more pumps in solar collectors, often black plastic tubes, the latter naturally warming the water which then joins the pool. To be effective, this device involves a large amount of sensors perfectly exposed to solar radiation. The gains are of the order of 3 to 10 ° C depending on the amount and exposure of said solar collectors.

Some owners of private outdoor pools use the pool cover or thermal blanket.

The pool cover is a natural heater. It is essential in addition to a home heating system. Put on the pool at night, it keeps the heat stored during the day. But it also helps to heat the pool water during the day. In addition to preventing heat loss from the water, the cover prevents evaporation of water and protects the pool from impurities that can fall into it during the night. It is very simple to use and economical. Heating the pool is becoming less and less expensive but still not very protective of the environment Solar pool heating is now one of the most profitable systems for heating water in a pool , whatever its size. Solar heating is based on a simple principle of recovering energy from the sun's rays, which is fed back into the water. Once installed, this heating mode costs nothing and emits nothing harmful to the environment.

Conscious of the evolution towards the solar heating, the author of the present patent worked and looked for a solution which would be able to produce a sufficient elevation of temperature of the water of a swimming pool by limiting considerably the cost of the investments, of maintenance and upkeep. Based on the current concept of solar radiation sensor panels, his thinking led him to use the constitution of "terrace blades", now made of resin to transform them into solar collectors, replacing the black plastic tubes that make up the panels. traditional solar systems used to date. When we know the surfaces of the terraces built in "terrace boards" which cover all or part of the ground surrounding a swimming pool, we know that these "terrace boards" each consist of several internal channels that can function as solar tubes and that in summer it is sometimes difficult to barefoot on said "terrace blades", it seemed to the inventor essential to use its kilometers of channels to heat the water of a swimming pool.

On the basis of the fact that a swimming pool equipped with a deck composed of "terrace boards" made of resin, already had the main element of a solar heating device, the author of the present invention simply imagined a means to connect together the different channels of each "terrace blade" and said "terrace blades" between them to form an important network of swimming pool water that heated by solar radiation would return to the basin, as it does today in solar panels.

The standardization of the "terrace decks" and the means of production now available to manufacture plastic elements at very low cost, has made it possible to design elements to be added to the ends of the standard "terrace decks" for commercial use. to connect them and to constitute an immense network of circulation of water.

For example, the connecting elements of the invention are preferably made by plastic injection, which consists of a single multi-cavity injection mold, to produce a large amount of injected elements at each press cost. Thus, by equipping an existing terrace made of "terraced blades" by junction elements placed at the free ends of said "terrace blade" and between each of them, said terrace becomes a network of water circulation exposed to solar radiation in which the pool water is sucked up and propelled by a simple pump to reach after the pool pool. By passing through the network thus formed, the pool water takes the calories transmitted by the sun. The economic performance of such a device being indisputable in comparison with all existing devices, the thermal performance can be significantly improved by the choice of material of the "terraces" or the arrangements that can be made as for example the inclusion of metal or other particles in the material prior to wire drawing or the addition of other components having increased temperature sensing capabilities during or after drawing.

Although several existing patents found in the state of the art prove an interest already shown for the transformation of "terrace boards" into swimming pool circulation network, none of the existing concepts presents the simplicity of the present invention both on the implementation, maintenance and maintenance plan and none provide such an important economic benefit. Indeed, the device of the present invention has the characteristic of being able to equip the existing terraces as new constructions, without significant installation cost, the installation can be performed by the user himself without it even needs to be professional.

The state of the art reveals for example a French patent CALANDRAS filed on 01/09/2010 and published on 02/03/2012 under the number 2 96 181 a device that tends to use for the same purpose the "terrace blades" which constitute the environment of some pool pools, as does the device of the present invention. It is evident from this CALANDRAS patent that the "terrace blades" provided by the inventor must be drilled in several places to receive connections allowing their water supply through collecting tubes placed under the terrace and therefore during the construction of it. This device is fundamentally different from the patent of the present invention which does not involve any drilling of the "terrace blades" and is applicable to a terrace already installed by very simple manipulation. Indeed, in the concept of the present invention, the simple equipment of the ends of said "terrace blades" by snapping is sufficient in most cases, the equipment of existing large surface terraces involves the interposition between each "terrace blades" assembled end-to-end, a seal element easily insertable by loosening said "terrace blades". Apart from the few devices approaching the present invention the state of the art reveals various devices to achieve the same result but totally differentiated from the present invention.

For example, mention may be made of the American patent Allocco filed on 09/08/1974 and published on 23/03/1976 under the number US Pat. No. 3,945,059 concerning a device for heating the pool water by propelling it into an integrated circuit under a lip preferably of metal.

Also mentioned is the French patent BONVARLET filed on 17/12/2002 and published on 18/06/2004 under FR 2 848 649 which mentions a solar heating system consisting of glass blocks, the water circulating in a pipe located on the one hand the glass blocks and on the other hand a bottom plate.

Many other devices use temperature exchangers located near or in the pool's pool environment but very few resort to the actual design of "deck boards" without making any changes to their integrity. The present invention relates to a device for heating the water of a swimming pool by passing it inside the "terrace blades" standard of a terrace exposed to sunlight, without making any changes to said "blades terrace 'of commerce.

The "terrace blades" constituting the surface of the terrace adjoining the swimming pool are made of resin or plastic, consisting of several internal channels juxtaposed parallel and usually four in number, square or rectangular section. The device of the invention is a combination of elements themselves plastic material designed to be integrated or reported at one and the other end of a "terrace blade" or group of "terrace blades" by fitting by force, latching, gluing or any other mechanical means, so as on the one hand, to communicate between them the different internal channels of each "terrace blade" and on the other hand to allow the communication of each "terrace blade" with the one and the other of the "terrace blades" which surround it
