VOLUME 7 MI2007 (10 0 0 3 64 I~mìlàno~ In the current state of technology and due to the current crisis, the use of stoves made of "pallets" of wood or logs or small pieces of wood or coal is spreading in all countries. These are usually placed against a wall of the room to be heated without the interposition of any insulating material when such a wall constitutes one of the external walls of the house. Yes This results in a significant dispersion of heat, especially that radiated from the rear wall of the stove, which is thus lost through conduction towards the outside. In addition to this, the heat radiation carried out by the two walls The sides of the stove will affect any furniture placed next to it, ruining its usually polished wooden surface. Since these radiations consist of frequency oscillations belonging to the useful infrared range, i.e. from 0.5 to 3 nanometers, they have the property of being almost entirely reflected by a surface, preferably metallic, that has been polished to a mirror finish. Such mirror-like sheets are commonly found on the market because they are used to replace glass mirrors, which are more expensive, fragile, and heavy. This invention has been created to avoid such inconveniences. nothing, since its modest cost is easily amortized by the fuel savings used to obtain the quantity of usable calories / hour not deducted from the amount of those wasted and without taking into account any damage caused. This equipment is described below for illustrative purposes only in general terms, since several minor details are not limiting to the practical implementation. The conveyor mainly consists of several walls of mirror-finish anodized aluminum sheets or in any case rigid sheets with a reflective surface arranged, on site, as in Fig. 1. The walls are usually and conveniently four in number for a type of stove 6 (Fig. 2) developed vertically with the combustion chamber arranged at the bottom just above the ash collection box and a second chamber at the upper end called the cooking oven. The hot air from the upper wall of the combustion chamber is usually conveyed to the upper chamber of the cooking oven, touching the external wall 7 which closes the rear part of the stove and for this reason the metal which constitutes this rear wall reaches a very high temperature and consequently creates a significant radiation of heat towards the wall 15 of the room. (Fig.2) The particular The purpose of this invention is to arrange two flat mirrors 2 - 3 angled at 90 degrees (right angle) to each other so as to reflect radiation horizontally, that is, direct it towards right and left of the stove as shown in Fig,2 with solid line arrows. In addition, two more flat mirrors 4 - 5 hinged to the sides of the first two at a 90 degree angle, convey the heat radiation towards the front, i.e. into the room. Starting from a height of a few dozen centimetres from the floor, the height of these mirrors should reach and exceed that of the group of pipes of the economizer dissipator usually present at the beginning of the exhaust pipe but omitted in the figure, after which the fumes have lost almost all the heat transported up to this point. The hinges 8 distributed throughout the assembly in Fig.1 in a minimum number of nine have a maximum opening of 90 degrees (right angle) so that it is easy for the installer to determine the exact angular opening of the mirrors. The central upright 9 / 10, preferably triangular in section, and the lateral uprights 11 and 14, suitably square or rectangular in section, rest on the floor of the room, while the upper ends of the joints 12 and 13 are equipped with rings or hooks for simple fixing to the wall 15 of Fig.2 which is located behind the stove. In this way, as already mentioned, it is easier to pack the mirror structure completely closed or partially disassembled into parts to be assembled by the user. For a further improvement in performance, two further extensions of mirrors 18-19 (Fig.2) can be foreseen which would also accentuate the screening towards the adjacent furniture but are not considered for cost reasons. In Fig. 2, the paths of the heat rays emitted from the rear face 7 of the stove 6 are shown, drawn with dashed lines. From the representation in Figure 2, it is easy to note that almost all of the heat rays that are radiated in a horizontal direction are conveyed towards the front of the stove of the present invention, including those emitted from the flue pipes, since the mirrors are designed to extend in height up to where the exhaust pipe assumes a high temperature compared to that of the ambient air.

Claims

Claims 1) Heat conveyor with hinged mirrors, to be installed behind domestic heating stoves, extending in height from the floor up to the multiple tubular dissipator of the flue gas outlet, if present, and for the entire remaining flue gas outlet pipe which reaches a high temperature during stove operation. 2) Heat conveyor according to claim 1) characterised in that the mirrors are joined on their vertical sides by a sufficient number of hinges which allow them to open up to a right angle so that the first two closest to the centre of the stove reflect in a lateral direction (towards the left and towards the right respectively) the heat radiation emitted by the rear wall of the stove which is the one with the greatest quantity of the total irradiated. 3) Heat conveyor according to claims 1) and 2) characterised in that a second pair of mirrors 4 and 5 of preferably equal height to that of the two previous ones are hinged on the edge of the latter so as to form a right angle with them so that they deviate in the forward direction of the stove the heat rays received by the mirrors 2 and 3, rays drawn with solid lines, just as they always reflect forward also the heat radiations emitted by the sides of the stove in the right and left horizontal directions indicated in Fig.2 with lines dotted. 4) Heat conveyor according to claims 1), 2), 3), characterised in that the assembly of mirrors hinged to each other are supported by at least three poles 9 / 10, 11 and 14 resting on the floor, the central one of which preferably has a triangular section, carrying the central hinges of the entire assembly, hinges which can be easily removed from them for dismantling the assembly and for compacting it for reasons of space during transport, in order to also allow the mirrors 2 and 3 to be closed like a book. 5) Heat conveyor according to the previous claims, made in such a way that the upper edges 12-13 of each pair of mirrors are equipped with a ring shaped so as to be easily hooked onto corresponding hooks previously fixed to the wall behind the stove, so as to support a good part of the weight of the assembly. 6) Heat conveyor with many other accessory parts according to claims 1) to 5) characterised by having been illustrated with simplified sketches which do not imply their correspondence to practical construction solutions except for their specific functionality, such description not constituting any kind of commitment since it is made for illustrative purposes only and not limiting.
