Pyrolytic oven with improved cooling

Abstract

The invention relates to an oven for household use, wherein the controls provided on the front control panel are protected against high temperatures by a ventilation system. The latter comprises a cooling air channel supported by shape coupling with the panel where the cooling air inlet and outlet apertures are located.

What is claimed is: 
     
         1 . An oven, comprising:
 a muffle wherein a plurality of walls surround a cooking cavity;   a channel in fluid communication with an environment outside the oven for the passage of a cooling air flow; and   a front panel arranged in front of the muffle, wherein the channel is secured to at least one of the front panel and the muffle by shape coupling.   
     
     
         2 . The oven of  claim 1 , wherein the channel further comprises:
 a hollow body with an outlet which is coupled to the front panel and is juxtaposed to apertures provided in the front panel.   
     
     
         3 . The oven of  claim 1 , wherein the air flows inwards and/or outwards with respect to the channel. 
     
     
         4 . The oven of  claim 3 , wherein the channel comprises an inlet for air coming from the environment outside the oven. 
     
     
         5 . The oven of  claim 1 , wherein the front panel has tangs which engage with the channel. 
     
     
         6 . The oven of  claim 1 , wherein the channel has appendices which engage with the front panel for securing the latter by shape coupling. 
     
     
         7 . The oven of  claim 1 , wherein the channel comprises spacer protrusions. 
     
     
         8 . The oven of  claim 2 , wherein the hollow body of the channel is essentially made out of two juxtaposed halves joined together along a peripheral junction edge. 
     
     
         9 . The oven of  claim 1 , wherein the channel has a base that rests on the muffle and has a surface extension which is smaller than that of the channel. 
     
     
         10 . The oven of  claim 9 , wherein the muffle comprises a relief on which the channel base rests. 
     
     
         11 . An oven comprising:
 a muffle wherein a plurality of walls surround a cooking cavity, the muffle comprising a relief;   a channel in fluid communication with an environment outside the oven for the passage of a cooling air flow; and   a front panel arranged in front of the muffle, wherein the channel comprises a base that rests on the relief of the muffle.   
     
     
         12 . The oven of  claim 11 , wherein the channel comprises spacer protrusions. 
     
     
         13 . The oven of  claim 11 , wherein the front panel includes a ventilation aperture. 
     
     
         14 . The oven of  claim 13 , wherein the channel is in fluid communication with the environment outside the oven through the ventilation aperture. 
     
     
         15 . The oven of  claim 11 , wherein the channel comprises two half-shells. 
     
     
         16 . An oven comprising:
 a muffle wherein a plurality of walls surround a cooking cavity;   a front panel arranged in front of the muffle and including a ventilation aperture; and   a channel in fluid communication with the ventilation aperture, the channel having an outlet mouth disposed on top of an inlet mouth.   
     
     
         17 . The oven of  claim 16 , wherein the channel is positioned on top of the muffle. 
     
     
         18 . The oven of  claim 17 , wherein the channel defines spacer protrusions. 
     
     
         19 . The oven of  claim 18 , wherein the channel comprises a base that rests on a relief of the muffle. 
     
     
         20 . The oven of  claim 19 , wherein the channel is configured to dissipate heat from the muffle.
