Description

 Device for winding flexible pipe and heating the water it contains by solar energy.

 The invention relates to a device for using a flexible hose of the garden hose or washing hose type for the production of hot water by exposure to sunlight.

 It also provides a solution to the problem of easy ltenrouleuent and on a low-density support of @@ s pipes for storage.

 The solar heating technique involves fixed sets of panels, domes, roofing elements and facades on carpets placed on the ground. A foldable envelope forming a pocket of water and dgiir is used in camping to produce a small amount of hot water for the toilet, but is an isolated case of using simple, common and economical means to avoid spending expensive energy to produce hot water in short moments of the day sanitary while during all the rest of the day we let lose a free solar energy.

 Now it is well known that a garden hose unfolded on the ground and exposed full of water to the rays of the sun quickly gives lukewarm, even hot, water; and furthermore the systems for winding these pipes are not provided to allow effective exposure and space-saving storage; thus the flexible hoses which are applied when they are empty of water are rolled up like a ribbon and are particularly economical in place; on the other hand thus stored they are empty of water and do not allow exposure to the rays of the sun in view of hot water production.

 Thus, in the current state of the art using flexible hoses, however very common, do not allow substantial recovery of the solar energy which they store.

 The invention therefore aims to overcome these shortcomings.

An object of the invention is to bring together in a single device the means of rolling up a flexible pipe and of heating by solar energy the water which it contains; this device is characterized by the fact that it comprises:
- means for flat winding of said pipe;
@ mobile and orientable support means for said coiled pipe;
at least one of the means necessary for the use of said coiled pipe as a solar collector absorber, namely a transparent cover disposed at the front part of said pipe, thermal insulation & the rear part, an air volume between the said cover and said pipe.

 According to one form of the invention, the device is also characterized by the fact that the distribution of the water contained in the said pipe is carried out sequentially by a thermostatic valve which opens when the said water reaches the desired temperature and its closes as soon as the hot water has run out, the said pipe is filled with cold water.

 According to another form of the invention, the device is also characterized by the fact that the distribution of the water contained in the said pipe is carried out sequentially by a pump which operates when the said water reaches the desired teupdrature and stops as soon as the hot water has drained the said pipe is filled with cold water.

 According to one of the preceding compositions, the device is also characterized by the fact that the water contained in said pipe once heated is introduced into a hot water network from a pressure tank.

 According to the composition which includes the said pump, this makes it possible to raise the pressure of the water when the said hose is used for washing or arreser.

 According to any one of the preceding compositions, the device which is the subject of the invention is characterized in that the said support for the winding means folds down against them so as to allow storage of small thickness.

 The description which follows, illustrated by appended drawings by way of nonlimiting examples, will make it possible to understand how the invention can come into practice.

 FIG. 1 represents a race view of the device equipped with a pump (8) and supplying a reservoir (10).

 Figure 2 shows a c8t view of the device fitted with a thermostatic valve (7).

 Figure 3 shows a cross section of the winding means (2), on a double scale from the others.

 Figure 4 shows a front view of the winding means (2) before brandhemont of the pipe (1).

 Figures 5 and 6 show side views of the device equipped with a pump (8) and used on one for the production of hot water4 on the other for watering.

 In FIG. 1, it can be seen that the device is supplied by the watering tap (11) and the hose (25) connected to the socket (12; the garden hose (1) wound inside the means of winding (2) is seen through a fictitious opening; the pump (8) discharges into the insulated tank and under pressure (10) through the insulated pipe (6), the insulated pipe (30) and the non-return valve (26); the said tank (10) supplies the hot water network (9) via the pressure limiting valve (28).

In Figure g we highlight the support means (3) consisting of the two front feet (13) extended by the wheels (14) and the rear feet (15) plug in the ground; the said rear feet (15) tilts on demand relative to the plane of the said front feet (13) which is also that of the winding means (2), which makes it possible to orient the device according to the height of the sun; the rotation of the available
say sitive by means of / wheels (14) around said rear feet (15) allows the orientation of the device according to the rotation of the sun during the day; the removable needle (20) which provides shade on the device allows a refined adjustment of the orientation; said feet (13) are extended by the handle (16) utiledttlorientation of the device and & its transport once the / rear feet (they) folded g the device is equipped in Figure 2 of said thermostatic valve (7) .

 Figures 7 and 2 note the great stability of the device thanks to said support means (3) despite the relatively large volume of the winding means (2), these having a diameter of the order of meter to contain a said pipe (1) 25 to 30 meters long; conversely, this large diameter allows for effortless winding.

 In Figure 3 there is a transparent cover (4) mounted in a frame (17) which rotates on the grid (18) and slides between two positions s the winding position which leaves free the passage of said pipe (1) which is plated between said grid (18) and the thermal insulating disc (5); the closed position where the end of said pipe (t) once fixed to the socket (12) integral with said frame (17) it is pressed against the aforementioned disc (5) on which it is locked by the hooks ( 19).

 We also note in this figure the central connection end piece (21) which serves as an axis of rotation inside the tube (31) fixed to the said front feet (13) and is extended at the rear by a fixed part thanks to the interposition of the sealed ring (22); there is finally the spring (23) which eonstitute an elastic connection of said grid (18) and said disc (5) in order to hold said pipe (1) well while allowing its free expansion during temperature rise.

 In Figure 4 there is the socket (12) above fixed on said frame (17) and the flexible (24) which extends said tip (21) and which can be grasped the end without difficulty to connect said pipe (1); there are also the radial and circular elements of the said grill (18).

 Figure 5 shows the use of the device in the heating phase; the connections to said valves (11) and Tank (10) are similar to those in FIG. the said nozzle (21) is connected to the gate valve (32) in the open position while the second valve (29) of the said pump (8) is closed t it should be noted that the said pump (8) is provided with an operating system controlled by a thermal probe so as to introduce into said tank only water at the required temperature; also note the possibility of direct use of said balloon (10) for the needs of the shower (27).

FIG. 6 represents the device in its use with watering and washing under pressure: the connection of said valve (11) is made by said valve (29) in the open position while said valve (32) is closed;
The thermally insulated pipe (6) of the previous figure is replaced at the outlet of the above-mentioned pump (8) by the said unrolled pipe (1).

 All these drawings are given as an indication but let glimpse the great interest * of the solutions which the invention allows and the possible triple use of the device made from the inventino: storage of the watering and washing pipes, production of domestic hot water increase in watering and washing pressure.

 However, it is known that a conventional installation for producing solar hot water is expensive, difficult to amortize and requires a system of bulky and often unsightly fixed solar collectors.

 An installation according to the invention makes it possible, at the cost of a lower yield, to be able to recover calories with removable appliances which are similar to gardening tools and have their advantages s simplicity-sturdiness, low price plus some of these appliances are already part of the gardener's range, in particular the pump, the hoses and the hose reel.

 Thus there is a good chance of achieving energy self-sufficiency in summer for a good number of households which are very sensitized by the recovery of solar calories but do not have the means to equip themselves with a sophisticated installation.

 Widely disseminated, the invention must allow a significant overall energy saving.
