Description

    AN OVEN COMPRISING AN EXHAUST DUCT
  • The present invention relates to an oven wherein heat convection to the outside environment is decreased.
  • Hot air circulates inside the oven cavity during the cooking process. The air circulating inside the oven cavity passes through an air channel and is discharged to the outside environment by means of an exhaust duct. Meanwhile, the oven walls situated in the vicinity of the air channel and the exhaust duct heat up with the effect of hot air passing through the air channel and heat convection to the outside environment is realized. The items located near the oven are damaged with the effect of the rising temperature. Especially the walls of a built-in oven, situated opposite the furniture are overheated and are deformed in the course of time.
  • In the state of the art Japanese Patent Document No. JP60164132, an oven is realized, that has a partition plate inside the air channel that provides the separation of the places through which the hot air and cold air passes.
