Definitions

  • This invention concerns a hydrothermal stove. To be more. exact, it concerns a high-yield stove which has been designed and embodied in the workshop of the author and which has. several uses.
  • It can be used for heating the surroundings in which it . is located by means of radiation, for heating the convective fluid which has to be circulated within suitable means that. radiate heat outside the stove, for heating washing water and for cooking and/or heating various substances.
  • the present invention tends to remedy such shortcomings - and drawbacks by embodying a high-yield hydrothermal stove..
  • the hydrothermal stove of the invention comprises conduits to convey water or convective fluid which are disposed or conformed, or shaped, so as to intercept and guide the flames and fumes of combustion along preferential paths in order to maximise the thermal yield of said stove - according to the invention.
  • the boiler can be embodied with materials able to provide excellent heat exchange.
  • the base supporting the wood. or fuel to be burnt consists helpfully of a substantially level battery of tubes acting as a hydrothermal grate.
  • conduit for fu-. mes and the conduits for convective fluid enfold spaces or . compartments inside the stove which are able to be used as ovens for cooking and heating.
  • the upper plate of the stove can be employed as a cooking plate.
  • This invention is embodied in a hydrothermal stove for household use, said stove being suitable for heating convective fluid and washing water and also for cooking foodstuffs and substances in general and being characterized by including in mutual cooperation and coordination:
  • the hydrothermal stove 10 shown in Figs.I ' and 2 has an inner upper part in which the elements forming- the boiler II and delimiting the combustion chamber 12 are . disposed; said elements are the conduits for convective fluid 13 and the battery of tubes 14, whereby said conduits for convective fluid 13 in particular are made with materials able to provide excellent heat exchange, such as steel, for instance.
  • the means 15 are located which control and regulate (Fig.5) the. flow of the convective fluid to be circulated into the out-. side hydraulic conduits.
  • the conduits for convective fluid 13 are conformed like a specially shaped panel provided with an interspace.
  • the form of said specially shaped panels makes it possible to embody a combustion chamber 12 having a substantially arched ceiling 16, and a suitable conduit for. fumes 17.
  • conduit for fumes 17 is delimited or. enfolded at least partially by the conduits for convective . fluid 13, a continuous exchange of heat can take place be- . tween said conduits 13 and 17.
  • the battery of tubes 14 arranged at the bottom of the combustion chamber 12 acts as a hydrothermal grate or support-. ing base whereupon the wood or solid fuel to be burnt is put.
  • Said battery of tubes I4 also enables the temperature of. the convective fluid within the conduits 13 to be kept even, since said battery 14 is located in such a way as to connect hydraulically the front 313 and rear 413 conduits forming the boiler II.
  • Beneath the battery of tubes I4 is a space 18 where a removable tray 19 for collecting the ash can be lodged.
  • conduits 13 delimiting said combustion chamber I2 and conformed, as said earlier, like a specially- shaped panel having an interspace have been given different. reference numbers depending on the specific position they oe- cupy.
  • conduits 113-213 are comprised which - are conformed like an arc-shaped panel so as to form said arched ceiling 16; said conduits 113-213 are separated at their top so that between them there is an upper transverse. opening 20 for the passage of fumes from the combustion chamber 12 into the discharge conduit 17.
  • the combustion chamber 12 is delimited at its front and - rear by the conduits for convective fluid 313-413, which are conformed like walls, whereby the front wall may include an- inlet 21 of a size such as to permit ready introduction of - the fuel.
  • the conduit for fumes 17 comprises a substantially level- first tract 117 delimited below by the conduit 213 and above by the plate of the hydrothermal stove 10, and thereafter comprises a descending tract 217 delimited by the conduit 213 and possibly by a conduit 513 shaped and disposed sub- . stantially vertically.
  • the lower end of the descending tract 2I7 communicates with the end rising tract 317 of the conduit for fumes 17, . and said end tract 317 leads into the stack 24.
  • valve 25 which is able to connect the tracts 2I7 and 3I7 of the conduit for fumes 17, whereby said valve 25 can be opened by hand 23 and/or auto-. matically; if the latter is the case, the signal for its operation can be monitored by a heat sensor located within the. boiler II and in contact with the convective fluid.
  • valve 25 enables the combustion fumes to be introduced directly into the stack 24 so that they'can be drawn away more efficiently, particularly so at the time.
  • a butterfly valve 26 can be envisaged as being in the stack 24 for this purpose . and can be operated by hand 27 or automatically, as in the . case of the valve 25.
  • the valve 25 is closed so as to make the discharge fumes. follow a longer path 217-317 and thereby to increase the surface of the conduits 13 affected by heat exchange.
  • the intensity of combustion can be regulated with means . 28 which deliver and convey a forced draught.
  • Said delivery means 28 consist of a conduit 29 (fig.4) disposed substantially beneath the boiler II so as to be able to communicate with the combustion chamber 12 in a semi-pressurised form.
  • Said conduit 29 is fed with hot air aspirated near the stove 10 by suitable fan means 30, whereby said fan means 30 are actuated by suitable heat sensor controlling means and . whereby said heat sensor can be located in the conduit for convective fluid 13 substantially near the point of emission of said fluid into the outside hydraulic circuit, said fan means 30 being actuated, moreover, in coordination with the mechanical opening of the window 31.
  • the opening of said window 31 is actuated by the same said heat sensor controlling means and said window 31 is disposed so as to shut off access to the conduit 29.
  • ther conduits 34 which are conformed coil-wise or with ano-. .ther like shape and are able to cause the circulation of any washing water to be heated inside the hydrothermal stove 10-and which comprise entry 35 and exit 36 conveyors, as shown- in Fig.4.
  • Said conduits 34 can be wholly immersed in the convective fluid and be separated from the inner walls of the conduit --13 or else can be secured to the-inside of at least one of ;the walls.
  • the boiler II has a plurality of through holes of which the aperture can be regulated and which are machined in the top of the conduit 213.
  • Said through holes 37 enable the upper plate 22 of the hydrothermal stove I0 to be heated more efficiently whenever necessary.
  • some refractory material is interposed in some zones between the boiler II itself and the outer containing structure 39 of the hydrothermal stove. -10.
  • said hydrothermal stove 10 comprises a lower -compartment 40 for lodging the means 15 which control and re--gulate the flow of convective fluid, said means 15 being, for -instance, of the kind shown diagrammatically in the hydraulic circuit of Fig.5..
  • the one-way valve 42 is thus by-passed and the convective fluid 41 can circulate within the outside hydraulic circuit 46.
  • the controlling and regulating means 15 also comprise an expansion tank 47 and/or other possible safety valves so as to keep the pressure of the convective fluid 41 constant or. to avoid dangerous excessive pressures within the hydraulic- circuit itself.
  • Fig.5 also shows diagrammatically the coil-shaped conduits 34 located inside the boiler II so as to enable the washing. water to be heated.
  • the flow of washing water inside the conduits 34 can be . regulated with a valve operated by a sensor located inside the boiler II, the purpose being to avoid possible dangerous overheating of the convective fluid 41 contained in said boiler II if ever the pump means 45 breaks down.
  • the hydrothermal stove 10 includes a door 48 to shut the combustion chamber or hearth 12 and a door 49 to shut the lower compartment 40.
  • Fig.6 shows an embodying variant of the invention comprising a compartment 50 which can be used as a cooking oven and which is located in a space formed by a suitable enlargement of the descending tract 217; said variant of Fig.6 also comprises one or more compartments 51 located below said fore-. going compartment 50 but not particularly affected by radiation of heat.
  • Fig.6 envisages that the valve 25 is disposed so as to cause the compartment 50 to be enveloped wholly or partially, ' and perhaps in a differentiated manner, by the discharge fumes.
  • the compartment 50 is used at least partially as a storage tank for washing water and is therefore connected hydraulically to the conduits 34 so as to enable a certain quantity of washing water to be pre-heated- by the discharge fumes, thus permitting said water to be kept at a substantially constant temperature at its outlet.
  • the water or convective fluid is pre-heated, before being introduced into the boiler II through the sleeve 33, by being made to flow - into a coil or suitable interspace made inside the stack 24; in this way the yield of the hydrothermal stove 10 is raised yet further.
  • conduits for . convective fluid 13 are conformed with a plurality of con- . -duits perhaps cooperating at least partially with baffle plate means.
  • conduit 34 is secured at its outside to a wall of the conduit for convective fluid 13.
