Description for industrial invention having as title;

“BOILER SUITABLE FOR OPEN FIREPLACES FOR THE PRODUCTION OF HOT AIR

FOR ROOM HEATING "

The object of the present invention is to improve to the maximum the functions required of traditional open fireplaces, which are mainly heating the environment, the possibility of cooking food on the grill and enjoying the direct view of the fire.

The present invention is the real thermo-fireplace that works open, without glass,

The present invention relates to an improved boiler for producing hot air which can be inserted into fireplaces of any shape and size.

The consequent primary purpose is to create a boiler in which the forced circulation of air aimed at heating does not disturb the normal activity of the fire.

A further object is to obtain from the operation of this boiler the maximum caloric efficiency with the minimum consumption of wood or coal.

These and still other purposes, which will appear more clearly later, are achieved by this forced air boiler characterized by several consecutive chambers where the ambient air is directed for the function of local heating, it is introduced at the bottom through a side duct which is also protected from the refractory wall, it reaches the first upper chamber that surrounds the register door and continues downhill for the subsequent 4 communicating chambers reaching the support base of the brazier with a high temperature, therefore without compromising the activity of the fire.

Further characteristics of the boiler are highlighted by the description of the embodiment illustrated in the attached tables of drawings in which:

table 1 represents the lateral section of the boiler where the ambient air inlet, part of the path and the outlet of the hot warning 8 is visible at the bottom 1, in the central part 12 there is a steel plate resting on the body boiler with accumulator and heat flywheel function.

In the upper part you can see the adjustable smoke register door 10-11, better visible in table 3.

Table 2 represents the front section of the boiler where a large part of the air path is visible, with entry at the bottom through a side duct 2, reached of the first upper chamber 3 and circulation around the smoke register door 11 in table 4, reached downhill of the second chamber 4 and subsequently of the third 5 and of the fourth chamber 6 and entry into the fifth chamber 7 through a central passage with arrival first under the brazier and then to the two outlet ducts 8.

The air circulation system, inside the boiler body just described, is the winning system for obtaining the maximum thermal result without disturbing the normal activity of the fire in the least, since the air arrives near the brazier or the support base. of the fire already at high temperature.

The ambient air drawn in from the outside of the house or room is forced in counter-current from top to bottom inside the boiler body, it heats up by recovering a large amount of heat and then exiting in the lower part of the fireplace is conveyed into ducts for distribution, if necessary, also in nearby premises.

The smoke register port 10-11 visible in all the tables positioned at the end of the boiler body and the beginning of the hood conveying the fumes towards the flue represents the second winning system. By maintaining an adequate opening, it guarantees a perfect draft of the chimney and therefore a reduced consumption of wood. The adjustment of the smoke register door 10-11 can be manual by means of a simple handle with 10 opening positions or automatic, managed by an electronic system.

The particularly simple structure allows excellent heat recovery and the shape of the whole allows installation in fireplaces of different shapes and sizes, the conveyor hood is built in masonry on site respecting the measures.

From what has been described and illustrated, it can be seen that all the intended purposes have been achieved by realizing an open thermo-fireplace capable of recovering the maximum heat produced by combustion without compromising the activity of the fire and the draft of the chimney.

Obviously the materials can vary according to the needs.

Claims (6)

CLAIMS Open termocamino, boiler for open fireplaces for the production of hot air for local heating, characterized by the fact of comprising a hearth surrounded by several consecutive chambers where the ambient air forced by a ventilation unit is introduced at the bottom through a lateral duct also protected by the refractory wall, reaches the first upper chamber that surrounds the register door and continues downhill for the subsequent 4 communicating chambers reaching the support base of the brazier with a high temperature, therefore without compromising the activity of the fire. 2. Open fireplace stove, as in claim 1, the boiler has the hot air outlets at the bottom, where this is introduced into insulated pipes for distribution in the room and / or nearby rooms, passing under or just above the level of the floor, At the outlet of the pipes there are metering outlets to always regulate the distribution at the bottom of the premises. 3. Open fireplace stove, in addition to the preceding claims, the boiler body has a register door on the top, surrounded by the first air circulation chamber, said register door fulfills the function of adjusting the draft of the chimney and consequently increasing the caloric efficiency of the boiler body and the reduction of wood consumption. 4. Open fireplace stove, in addition to the previous claims, the presence in the boiler body of a register door described in claim 3 has two movement possibilities, the first manual through a handle with ten opening positions, the second automatic motorized with movement controlled by a system electronic modulation, assisted by thermal detectors. 5. Open fireplace stove, in addition to the preceding claims, considering that the boiler has a weight of metal material of over 130 kg, combined with the same refractory material, when both reach the ideal temperature it guarantees a large production of hot air with a minimum consumption of wood. 6. Open fireplace stove, in addition to the preceding claims, it should be noted that together with heating the fireplace it can be used at the same time to cook on the grill without there being any fumes in the room since these are sucked in thanks to the suitably adjusted register door.
