  • the oven (1) comprises a body, a cavity (2) disposed within the body, wherein the foodstuffs to be cooked are placed, a casing (3) surrounding the cavity (2), at least one heater (4) disposed in the cavity (2), an insulation material (5) wrapped around the casing (3) and insulating the cavity (2) and a warmer compartment (6) disposed outside the cavity (2) and wherein the precooked foodstuffs are placed to be kept warm.
  • the oven (1) of the present invention comprises a heat retention unit (7) disposed between the casing (3) and the warmer compartment (6), contacting the outer surface of the casing (3) and/or the insulation material (5), wherein the phase changing material (PCM) is placed, and heating the warmer compartment (6) by being charged with the residual heat remaining in the casing (3) and the insulation material (5) at the end of the cooking process.
  • PCM phase changing material
  • the process of keeping the foodstuffs warm is generally realized after the cooking process, when the heaters (4) are closed.
  • the casing (3) and the insulation material (5) absorb a substantial amount of residual heat during the cooking process and this stored thermal energy is transferred by heat transfer to the heat retention unit (7) that contacts the casing (3) and/or the insulation material (5) wrapping the casing (3), and that comprises phase changing material (PCM).
  • the phase changing material (PCM) in the heat retention unit (7) is charged by the said residual heat, dissipates the stored latent heat by changing phase after the cooking process is completed and heats the warmer compartment (6) with this released latent heat.
  • phase changing material (PCM) is placed that changes phase at the temperature value a little above the temperature that the foodstuffs are desired to be stored. For example, if the foodstuffs are desired to be kept warm around 75 - 80 °C, then the phase changing temperature is selected around 80 - 100 °C.
  • the warmer compartment (6) is disposed below the casing (3) and the heat retention unit (7) forms the ceiling of the warmer compartment (6).
  • the heat retention unit (7) is in form of a flat box with dimensions to almost entirely cover over the warmer compartment (6) and has an upper surface (8) contacting the casing (3) and/or the insulation material (5) and a lower surface (9) facing the warmer compartment (6).
