[0001] DESCRIPTION

[0002] TITLE: Cooking appliance provided with a cooking fume filtration device

[0003] Technical field

[0004] The present invention relates generally to a cooking appliance for cooking food products, and in particular to a hot air cooking appliance.

[0005] State of the art

[0006] Document US2022 / 0202239 discloses an electric cooking appliance for cooking food, in particular using a hot air cooking method. Such an electric cooking appliance comprises:

[0007] - a cooking container defining a cooking chamber,

[0008] - a fan configured to generate an airflow in the cooking chamber, and

[0009] - a heating device configured to heat the airflow generated by the fan.

[0010] When such an electric cooking appliance is used for cooking meat or fish, dense and odorous cooking fumes escape through an exhaust opening fluidly connected to the cooking chamber, which proves unpleasant, or even toxic, for a user and therefore requires ventilation of the room where the cooking appliance is located.

[0011] In order to overcome such a drawback, it could be envisaged to equip the electric cooking appliance with a filtration device configured to filter the cooking fumes generated in the cooking chamber before they are discharged outside the electric cooking appliance.

[0012] However, the presence of such a filtration device prevents direct evacuation of water vapor emanating from the food cooked in the cooking chamber, for example when cooking fries, and is therefore likely to induce saturation of water vapor in the cooking chamber, which slows down the cooking of the food or even prevents it from cooking correctly.

[0013] Summary of the invention The technical problem underlying the invention therefore consists of providing a cooking appliance for cooking food, for example using a hot air cooking method, which ensures optimal cooking of food likely to release a significant amount of water vapor during cooking, while making it possible to filter cooking fumes generated during cooking of food generating a lot of cooking fumes, such as meat or fish.

[0014] To this end, the present invention relates to a cooking appliance, such as a hot air cooking appliance, configured for cooking food, the cooking appliance comprising:

[0015] - a cooking chamber,

[0016] - an air exhaust circuit fluidly connected to the cooking chamber, the air exhaust circuit comprising an exhaust opening through which cooking fumes, generated in the cooking chamber, are discharged outside the cooking appliance,

[0017] - a filtration device configured to filter cooking fumes flowing into the air exhaust circuit,

[0018] - a user interface configured to allow a user to select at least one operating parameter of the cooking appliance, and for example at least one operating mode of the cooking appliance, and

[0019] - a control unit configured to control the operation of the cooking appliance, the filtration device being configured to obstruct a passage section of the air exhaust circuit when the cooking appliance is in the first operating mode.

[0020] The cooking appliance comprises a first operating mode in which the filtration device is configured to filter cooking fumes flowing in the air exhaust circuit and a second operating mode in which the cooking fumes, flowing in the air exhaust circuit, are able to flow freely, i.e. directly (and therefore without being filtered), towards the outside of the cooking appliance, and the control unit is configured to control the operation of the cooking appliance according to the first operating mode or according to the second operating mode depending on an operating parameter selected by a user via the user interface.

[0021] Such a configuration of the cooking appliance makes it possible: - when a user wishes to cook food that generates a lot of cooking fumes and odors (such as meat or fish), to control operation of the cooking appliance according to the first operating mode so as to ensure filtration of the cooking fumes, generated in the cooking chamber, by the filtration device, in order to trap the odors and / or harmful or toxic particles carried by the cooking fumes, and

[0022] - when a user wishes to cook a food that generates little smoke and odor (such as fries cooked with a very small quantity of oil) or which requires regular evacuation of the water vapor generated in the cooking chamber (in order to avoid saturation with water vapor in the cooking chamber which could harm the cooking of the food received in the cooking chamber), to control operation of the cooking appliance according to the second operating mode so as to ensure free evacuation of the cooking fumes or water vapor generated in the cooking chamber, in order to ensure optimal cooking of said food.

[0023] Thus, the cooking appliance according to the present invention ensures optimal cooking of a wide variety of foods, while avoiding pollution of the environment of the cooking appliance.

[0024] Furthermore, such a configuration of the cooking appliance makes it possible to filter cooking fumes only when such filtration is required, which makes it possible to extend the service life of the filtration device and therefore to space out the replacement phases of such a filtration device.
