Descripción detallada de una realización de la invenciónDetailed description of an embodiment of the invention

En referencia a las Fig. 1 y 2, una realización de horno 1 de cocción comprende un recinto 3 de cocción conformado mediante una pared trasera 2 vertical y varias paredes adyacentes 2a metálicas de horno, y un grupo calefactor 4 fijado sobre dicha pared trasera 2, para generar un caudal de aire caliente 6 forzado distribuido por todo el recinto 3. El grupo calefactor 4 comprende un ventilador radial de álabes 8 movido por un motor 9 y un eje 10 rotatorio de ventilador impulsando el caudal caliente 6, un panel soporte 11, 12 de caldeo en forma de placa plana con dos caras anterior 11a y posterior 11b portando en una de ellas una resistencia de caldeo 12 plana en contacto térmico con la cara 11a, 11b respectiva, y un dispositivo de unión y de soporte 7 único fijado a la pared trasera 2, todos ellos montados como un sub-conjunto único 7, 8, 9, 11, 12, también incluidos los medios de conexión 16 eléctrica.Referring to Figs. 1 and 2, an embodiment of baking oven 1 comprises a shaped cooking chamber 3 by means of a vertical rear wall 2 and several adjacent walls 2a oven metal, and a heating group 4 fixed on said rear wall 2, to generate a forced hot air flow 6 distributed throughout the enclosure 3. The heating group 4 comprises a radial blade fan 8 driven by a motor 9 and a shaft 10 Rotary fan driving hot flow 6, a panel 11, 12 flat plate-shaped heating with double sides previous 11a and later 11b carrying in one of them a flat heating resistance 12 in thermal contact with face 11a, 11b respectively, and a single connection and support device 7 fixed to the rear wall 2, all mounted as a single subset 7, 8, 9, 11, 12, too including electrical connection means 16.

El panel de caldeo 11, 12 portador de la resistencia 12 preferentemente es configurado como una lámina substrato 11 substancialmente plano, sobre una de cuyas caras anterior 11a o posterior 11b es puesta en contacto térmico una resistencia plana o preferentemente depositada una resistencia de película gruesa 12, con el fin de mejorar la transmisión térmica al panel-substrato 11, el cual está hecho de una lámina metálica recubierta de un aislante eléctrico y a la vez buen conductor térmico.The heating panel 11, 12 carrier of the resistance 12 is preferably configured as a sheet substantially flat substrate 11, on one of whose faces anterior 11a or posterior 11b is thermally contacted a flat resistance or preferably deposited a resistance of 12 thick film, in order to improve thermal transmission to panel-substrate 11, which is made of a metallic sheet covered with an electrical insulator and at the same time good thermal conductor.

El grupo calefactor 4 está montado sobre la pared trasera 2 del horno únicamente a través del dispositivo de unión 7, el cual es fijado directamente a la pared trasera 2 del recinto, mediante tornillos o accesorios de fijación rápida del tipo de giro y enclavamiento, no representados en los dibujos. El dispositivo de unión 7 se conforma con una placa central 7a circular que se pone en contacto con la pared trasera 2, y desde su periferia se extienden varios brazos radiales 13 extendidos en forma de embudo divergente hacia el recinto 3, dejando entre ellos unas aberturas 14 de paso de aire. La placa central 7a es atravesada por el eje rotatorio 10 del ventilador sujetándolo, para el soporte del ventilador 8 y su motor 9 en el grupo calefactor.The heating group 4 is mounted on the wall rear 2 of the oven only through the joining device 7, which is fixed directly to the rear wall 2 of the enclosure, by means of screws or quick fixation accessories of the rotation type and interlocking, not represented in the drawings. The device of junction 7 conforms to a circular central plate 7a that is placed in contact with the rear wall 2, and from its periphery extend several radial arms 13 extended funnel-shaped divergent towards room 3, leaving openings between them 14 air passage. The central plate 7a is crossed by the shaft Rotary fan 10 holding it, for the support of the fan 8 and its motor 9 in the heating group.

El panel-substrato 11 portador de la resistencia de caldeo 12 es de forma substancialmente anular con un diámetro exterior referenciado en la figura 1 como "De", y está hecho de una lámina metálica tal como de acero inoxidable por su rigidez para el acoplamiento al dispositivo de unión 7. El substrato anular 11 tiene una abertura central 11c de diámetro "Di" sobre cuyo borde se soporta unido a los extremos 13a de dichos brazos radiales, quedando en un plano paralelo al de rotación de los alabes 8 y separado de la pared trasera 2 por un espacio de anchura "W". La longitud del eje 10 del ventilador atravesando dicho espacio "W", determina una distancia de separación equivalente entre el plano de los álabes 8 y la pared trasera 2.The panel-substrate 11 carrying heating resistance 12 is substantially annular with an outside diameter referenced in Figure 1 as "De", and It is made of a metal sheet such as stainless steel by its rigidity for coupling to the connecting device 7. The annular substrate 11 has a central opening 11c in diameter "Di" on whose edge it is supported joined to the ends 13a of said radial arms, being in a plane parallel to that of rotation of the blades 8 and separated from the rear wall 2 by a "W" width space. The length of the fan shaft 10 crossing said space "W", determines a distance of equivalent separation between the plane of the blades 8 and the wall rear 2.

Entre ambas la pared trasera 2 del horno y el substrato 11 se conforman los conductos de impulsión de una parte del caudal 6 de aire caliente, que es dirigido al recinto 3 de cocción primero a través de los huecos 14 entre los brazos radiales 13 de soporte, sobre la cara posterior 11b del panel de caldeo 11, 12, y después distribuido a través del espacio periférico entre el grupo calefactor 4 y las paredes adyacentes 2a del horno. La periferia circular de los álabes 8 rotatorios debido a su diámetro "Df" menor que el diámetro "Di" de la abertura 11c, queda substancialmente interpuesto en el panel de caldeo 11, 12, por lo cual una parte del caudal de aire 6 caliente es debido también al caudal de aire de admisión 5 central aspirado por el ventilador 8, que recorre la cara anterior 11a del panel de caldeo.Between both the rear wall 2 of the oven and the substrate 11 the ducts of a part are formed of the flow 6 of hot air, which is directed to the enclosure 3 of cooking first through the holes 14 between the radial arms 13 support, on the rear face 11b of the heating panel 11, 12, and then distributed through the peripheral space between the heating group 4 and the adjacent walls 2a of the oven. The circular periphery of the rotating blades 8 due to its diameter "Df" smaller than the diameter "Di" of the opening 11c, remains substantially interposed in the heating panel 11, 12, so which part of the flow of hot air 6 is also due to the central intake air flow 5 sucked by fan 8, which runs along the front face 11a of the heating panel.

El grupo calefactor 4 es instalado como un sub-conjunto de suministro único sobre la pared 2 trasera del horno, mediante una sola operación de montaje del grupo calefactor 4 entero, incluido el motor 9 del ventilador y su aislamiento térmico. Para su instalación, el grupo calefactor 4 es introducido desde la boca del recinto 3 pasando el motor 9 al exterior del horno. La abertura 15 en la pared trasera 2 necesaria para ello es de un diámetro mayor que el diámetro "Dm" del motor 9. La placa central 7a de soporte es de un diámetro "Ds" mayor que la abertura de paso 15 en la pared, por lo cual es puesto en contacto con la pared trasera 2 interiormente.The heating group 4 is installed as a single supply sub-assembly on wall 2 rear of the oven, by a single assembly operation of the group  4 full heater, including fan motor 9 and its thermal isolation. For installation, heating group 4 is introduced from the mouth of enclosure 3 passing the engine 9 to oven outside. The opening 15 in the rear wall 2 required for this it is of a diameter greater than the diameter "Dm" of the motor 9. The central support plate 7a is of a diameter "Ds" greater than the passage opening 15 in the wall, whereby it is placed in contact with the rear wall 2 internally.

Debido a esta disposición del grupo calefactor 4 sobre la pared trasera 2, los cables de conexión eléctrica 16 de las resistencias de caldeo son conducidos hasta el exterior del horno a través del espacio intermedio de anchura "W", guiados sobre los brazos radiales 13 del soporte, terminando la operación de instalación del grupo calefactor 4 en el recinto 3 del horno.Due to this arrangement of heating group 4 on the rear wall 2, the electrical connection cables 16 of the heating resistors are conducted to the outside of the oven through the intermediate space of width "W", guided on the radial arms 13 of the support, finishing the operation of installation of heating group 4 in room 3 of the oven.
