Definitions

heating element 30 When mounted on wall 12 of the cooking chamber, heating element 30 is associated to a fan, not shown, which is located in the area defined by central body of the butterfly, so that curved central portion 32 follows the outline of said fan. Therefore, air sucked from the cooking chamber is directed first toward heating element 30, then to side portions 34, 36, to maximise heat exchange.
the centre of the fan is also the centre of curved portion 32.
a traditional tubular heating element provided with circular shape can be combined with the butterfly shaped element 30.
restrictions 53, 55, of side portions 54, 56 join central portion 52, whose size is larger than that of restrictions 53, 55, with a profile that is asymmetrical with respect to a longitudinal axis Y extending through the centre of baffle 16.
restriction 53 of side portion 54 has a lower profile 53a substantially circular, and an upper profile 53b substantially linear.
restriction 55 of side portion 56 has a lower profile 55a substantially linear, and an upper profile 55b substantially circular.
heating assembly 14 is to generate a forced flow of air from chamber 10 into assembly 14 through holes 18 and then back to chamber 14 through holes 19, 19', whereby air re-introduced into chamber 10 is heated.
