The present specification is part of the application for a utility model relating to a compact thermal accumulator, the technical purpose of which is to form a heat-accumulating element to be placed inside fixed or portable radiators, formed by an internal electrical resistance element or other heat generating device assembled inside them, and by an outer enveloping casing.

It consists of two radiating panels, with high mechanical resistance and elevated thermal capacity, such as that offered by porcelain stoneware, which are placed parallel and separately, to facilitate the passage of the convective air currents circulating between them, being installed in a framework formed by two transverse plates, between which an electrical resistance element is assembled. The assembly is completed with a low front plate provided with two perpendicular partitions made from a suitable material.

The object of the invention consists of acting as a heat accumulator in the phase in which the radiator to which it is incorporated acts, electrically connected, as a convector, and that of returning the heat when said radiator is electrically disconnected, for which connection and disconnection purposes it has the appropriate temperature sensors and other suitable electrical devices (not depicted in the figures).

The applicant has knowledge of the existence of various accumulators which use water, oil or other materials for such purpose; he also has information about electric radiators working by convection, further knowing of the existence of radiators provided with heat accumulation means, and all with a view to desired savings in electric power consumption.

However, the applicant has no knowledge of the existence of an accumulator, formed by radiating porcelain stoneware panels, having the particularity of acting by absorbing heat when the corresponding radiator to which it is applied is connected to the electric system and acting as a convector, later returning the heat, when it is disconnected, in the form of heat radiation striking against another radiating panel, which is also made from porcelain stoneware, which together with the indicated casing, closes the corresponding radiator, inside of which the accumulator object of the present invention is located. And, of course, the applicant does not know of any thermal accumulator in which porcelain stoneware panels are integrated, in any technically feasible manner, in the way in which it is proposed by the present invention.

The thermal accumulator herein proposed is configured as a component of electric radiators formed by a radiating panel and a closure casing, in replacement of the simple electrical resistance elements assembled inside conventional radiators, to which accumulators using certain liquids or other materials, as previously indicated, can eventually be added internally.

The radiator in which the invention is incorporated starts up by means of the actuation of a simple switch, acting in a normal manner with an electrical connection until a sensor detects that the temperature of the environment is at a level which is preset as ideal, immediately being electrically disconnected, no longer acting as a convector and operating solely and exclusively by radiation of its inner and outer panels, all made from porcelain stoneware, being necessary to stress that the outer panel receives the radiations from the inner panels of the thermal accumulator object of this invention. This occurs until said sensor detects a preset drop in the ambient temperature, at which time the corresponding electrical connection is again re-established.

To aid in better understanding what is being described, four sheets of drawings are attached in which the following figures have been depicted with an illustrative and non-limiting character with respect to the compact thermal accumulator object of the invention:

• Figure 1 shows a plan view.
• Figure 2 shows an elevation view.
• Figure 3 shows a side view.
• Figure 4 shows an axonometric perspective view.

In view of such figures, the following can be contemplated:

How the thermal accumulator of reference (1) is formed by two transverse plates (2), by two porcelain stoneware panels (3), by an electrical resistance element (4) and by two insulating partitions (5) assembled on a front plate (6).

And how the transverse plates (2), the panels (3) between the former and the electrical resistance element (4) are arranged, and of how the partitions (5) are arranged on the front plate (6).
