APPARATUS
*fee 0 SOo S0a 0*00 toS The following statement is a full description of this invention, including the best method of performing it known to us:

0. go: GH&CO REP: 18250-B:RPW:RK 18250B:406 t 1A RADIATING CONVECTION HEATING APPARATUS The present invention relates to a radiating convection heating apparatus.
As is known, so-called heater fans are already commercially available and are substantially constituted by an electric resistor arranged in a flow of air generated by a fan which thereby facilitates the rate of heat exchange from the resistor toward the environment These solutions have the disadvantage of not allowing a good heating of the environment, since the presence of an electric resistor exposed to the air does not allow to provide uniform heating effects and the heating element, by having no heat inertia, in practice ceases its effect immediately as soon as the power supply is disconnected.
So-called oil radiators are also known; said radiators 15 are substantially constituted by a body which is composed of a plurality of columns which in practice define a chamber for containing diathermic oil which is heated by a resistor
O
which is generally arranged in a lower part of the chamber.
This solution creates the advantage whereby a 20 considerable mass is heated which acts as a thermal buffer which maintains a production of heat toward the environment even when the electric resistor is switched off.
However, ir these embodiments it is not possible to increase heat exchange by means of forced ventilation, due to the difficulty encountered in havirg a good distribution of the air flow when said air flow is directed against the columns of the radiator which in practice constitute the heating element.
I 2 Accordingly, the present invention provides, in one of its embodiments, a radiation convection heating apparatus comprising two side wall compartments, a plurality of column-like elements arranged between said compartments and extending between a lower manifold and an upper manifold so as to define a containment chamber for diathermic oil heated by means of an electric resistor, characterized in that the apparatus further comprises a fan having an air flow delivery connected to a heat exchange duct which extends inside the upper manifold and exits at one of the side wall compartments.
This embodiment of the invention solves one of the above described problems in that it provides a radiating convection heating apparatus whicJ despite having a mass of diathermic oil which is heated by a resistor, allows to also use a forced ventilation which facilitates heat exchange without thereby creating non- S• uniformities in heating.
".This allows to optimize heat exchange by using 20 forced ventilation, achieving a significant increase in o: the outward production of heat.
In another embodiment of the present invention a heating apparatus is provided which allows to humidify the environment, thus restoring the natural equilibrium 25 in said environment. eeoc One advantage of the embodiments of the present S"invention is that a heating apparatus can be easily •obtained starting from commonly commercially available .elements and materials and is furthermore competitive from a merely economical point of view.
VeT-k> Further characteristics and advantages will become apparent from the description of a preferred but not exclusive embodiment of a radiating convection heating apparatus, according to the present invention, illustrated only by way of non-limitative example in the accompanying drawings, wherein: figure 1 is a schematic front elevation vAew of the heating apparatus according to the invention; figure 2 is a lateral elevation view of the heating apparatus; figure 3 is a partially cutout view of the heating apparatus, illustrating the upper manifold and the heat exchange duct; figure 4 is a sectional view of the fan; 15 figure 5 is a sectional view, taken along the line V-V of figure 4.
With reference to the above figures, the radiating convection heating apparatus according to the invention, which is generally indicated by the reference numeral 1, 20 comprises two side wall compartments, respectively indicated o by 2 and 3, which are advantageously but not necessarily mounted on castors 4. Between the side wall compartments 2 and 3 there is a plurality of column-like elements 5 which extend between a lower manifold 6 and an upper manifold 7, 25 so as to define a chamber for diathermic oil which can be heated by means of an electric resistor which is generally arranged at the lower manifold 6.
An important peculiarity of the invention is constituted by the fact that in one of the side wall compartment, for example in the side wall compartment 2, 4 there is a fan 10, the intake whereof is arranged at an opening 11 which allows to draw air at the interspace defined in the side wall compartment, so that the air is drawn in from below and is preheated by striking the face of the side wall compartment which is directed toward the heating elements.
The fan 10 is provided with an impeller 12, of a per se known type, advantageously with radial vanes, which feeds the flow of drawn air into a delivery duct 15 which is accommodated inside the side wall compartment 2 and is connected, in an upward position, to a heat exchange duct which extends inside the uppermanifold 7, so that in practice the air strikes the heating body from the inside, so that it undergoes an easy heating without dispersions or i' 15 non-uniformities of flow toward the outside.
The heat exchange duct 20 exits at a grille 21 which is 0* 555 directed outward and is advantageously provided on the other side wall compartment 3.
Another important aspect of the invention is 20 furthermore constituted by the fact that the heating 5.55 apparatus, according to the invention, comprises a a humidification unit, generally indicated by the reference
*SSO
numeral 30, which is constituted by a storage tank 31 and by
S
a humidification tank 32 which are mutually connected by 25 means of a lower duct 33 so as to obtain in practice two communicating vessels.
Inside the tank 32 there is a heating resistor 34 for humidification, which can be independently powered and allows to create steam in a limited region of water, since in practice only the humidification tank is heated, allowing a good delivery of humidification steam, which escapes by means of an upper grille, generally indicated by By means of the described arrangement, it is thus possible to provide a radiating convection heating apparatus which contains diathermic oil and offers the possibility of performing forced-ventilation heating, using the flow of the ventilation air inside the heating body, i.e. inside the heat exchange duct which is arranged coaxially inside the upper manifold.
The invention thus conceived is susceptible to numerous modifications and variations, all of which are within the scope of the inventive concept.
All the details may furthermore be replaced with other technically equivalent elements.
15 In practice, the materials employed, as well as the dimensions and the contingent shapes, may be any according to the requirements.
