FR2460447A1 - Domestic fireplace with water and air heaters - has water heater in series with back boiler and two air circuits for room - Google Patents

Abstract

The fireplace consists of a hearth (1) with a low level water heater (7) and a fresh air inlet (6). The heater is in series with a back-boiler (2) so that an air space exists between it and the rear (12) of the fireplace. Water, from the central heating, is supplied through the return pipe (11) and, after re-heating, returns through the flow pipe (8). Fresh air, drawn through the intake (6), passes under the hearth and between the back boiler and rear (12) of the fireplace before entering the room through the outlets (10). A secondary air circuit is installed on each side of the fireplace. Room air enters the under-hearth inlet duct (5) and flows through the metallic duct (3) into a plenum (4) which runs around three sides of the mantlepiece. The warmed air exhausts through the outlet (9). An electric immersion heater is fitted in the water circuit for night time operation.

Description

 shit is, frankly fear second homes, chimneys, more or less monumental, on an apparent wood fire, but we quickly realized that, if it was a peetic spectacle, the calorific output was deplorable and it This is why many inventors have sought to improve existing chimneys by pretending to predicate them over time with hot air and hot heat.

 The solution, proposed below, takes up the problem at the base because it is no longer a question of modifying an existing chimney, hands to design a new chimney answering these needs.

The attached figures schematically giving an example of what such a fireplace can be made. It can be made in all styles, in all dimensions and various materials can be used while respecting the principles of the invention.

Fig.I is a front view, fig.2 a side view with a partial cutaway.

Heating is conventionally done by placing the logs on andirons placed on the plate (I) of the fireplace, or on a grid.

 The hot water circuit has two coinnuniquants tanks one (7) is horizontal and placed under the plate (1) of the hearth, the other (2) is lying vertically at the bottom of the hearth but without touching the wall. lower tank is heated by the fire which is above it the other is licked by the flames.

The warm water, in return for the circuit of the apartment enters the reserve (7) by the canslisation (II), warmed it goes into the tank (2) and, become hot, it comes out of it by (8) to return in the circuit which includes radiators and taps.

If the size of the installation requires it, a flow rate accelerator can be fitted.

 Air heating takes several circuits.

 The first is substantially in the median axis of the chimney the air taken into the room (or outside) enters through the opening (6) under the plate (I) of the hearth and heats up on contact .- If he licks the water tank (7) which gives him some calories and goes into the box (12) which is in the space reserved between the water tank (2) and the bottom, it comes out of it naturally through the openings (10) provided in the mantea @ of the chimney to spread into the room @ minus, as a variant that is adapted to these openings in the pipes which will lead it to other painted house .

The second air circuit follows two routes which are parallel and which frame the hearth, one on the right and the other on the left. - The air enters through openings (5) also placed below the hearth plate (I) and go directly into metal boxes (3) which constitute the right and left sides of the chimney and which directly receive the radiation of the hinds
Of these boxes the hot air collects in the strip (4) which surrounds three sides of the chimney and yes is made of a metal box.- The air comes out through openings (9).

 For the hot air circuit, in some cases it may be necessary to use fans to accelerate the current.

Finally, it is necessary to foresee the case of particularly cold periods and during which it is necessary to have a good temperature day and night. during the night.- An additional electric heating has been provided, started automatically by a thermestat, which can supply the water contained in one of the tanks with the missing calories
It should be noted that at no time does the air in the circuit come into contact with ash or smoke, so it remains pure.

Claims (2)

R E V E N D I C A T I O N S 00000  1 - Chimney with apparent wood fire which can provide at the same time a circulation of hot water and an emission of pulsed hot air, naturally or artificially. - This is a specially studied chimney and not an arrangement of an existing chimney - It is characterized by the presence in the water circuit of two tanks in series, one under the hearth plate , the other behind the flames.  2 - Salt chimney @ n claim N I characterized by the presence of a double network for the production of hot air.- The first is substantially placed in the median axis of the chimney The air enters under the hearth plate, passes under the lower hot water tank, enters a box behind the upper water reservoir and exits through openings in the chimney breast. second circuit has two parallel routes framing the hearth.-the air still enters under the hearth plate but is directed into two metallic boxes which form the right and left blocks of the chimney and joined at the top by a strip also in box, it is in the strip that the hot air outlets are arranged.  32Fireplace according to claim iTol characterized by the presence of an auxiliary electric heater, started by thermostat and which supplies the water from a reservoir, the calories made necessary by the reduction in intensity of the hearth, noted nendent the night during which you can not recharge as regularly as during the day.
