Title: Device for avoiding the formation of smoke in ovens
IPC: F24C15/14
Filed: 1983-02-17
Abstract: A device intended to avoid liquid grease produced by food 12 located on a grid 10 placed in a cooking oven when it is heated falling on the hot parts of the oven, such as the broiler pan or the bottom of the oven where it carbonises and thus produces unpleasant smoke, comprises an absorbing material 16 having a low specific heat, for example made of glass wool, supported by a frame 18 fastened to uprights 20 under the grid 10.
