[0002] A cooking apparatus is known from the prior art, the cooking apparatus being configured to cook food, and comprising:

[0003] - Housing, which includes a receiving and accommodating portion;

[0004] - A cooking container configured to occupy an insertion position and a removal position, wherein in the insertion position the cooking container is at least partially disposed in a receiving portion, and in the removal position the cooking container is at least partially removed from the receiving portion, the cooking container comprising:

[0005] o Cooking box, which is configured to hold food to be cooked and is accessible to the user when the cooking container is in the removed position; the cooking box and the housing are configured to define the cooking chamber when the cooking container is in the inserted position.

[0006] o Front panel, which is configured to extend at least substantially toward the front of the cooking box;

[0007] o A first transparent wall, which is mounted on the cooking oven and configured to at least partially close a first through hole provided on the cooking oven;

[0008] o A second transparent wall, which is mounted on the front panel and configured to at least partially close the second through hole provided on the front panel;

[0009] an airflow duct, which is at least partially formed by a first transparent wall and a second transparent wall and configured to allow cooling airflow between the first transparent wall and the second transparent wall; and

[0010] A hot air heating system, which is disposed in a housing and configured to heat and cook food present inside the cooking chamber according to at least one hot air cooking mode.

[0011] This type of electric cooking appliance is efficient because it allows the user, especially according to the hot air cooking mode, to cook the food set in the cooking chamber. The presence of the first and second transparent walls allows the user to obtain visual indication of the cooking of the food in the cooking container during the operation of the electric cooking appliance, even when the cooking container is in the inserted position.

[0012] However, a drawback of this electric cooking device is that the first and second transparent walls are opaque when used in the hot air cooking mode. In fact, the proximity between the cooking chamber and the airflow duct can cause moisture-laden air present in the cooking chamber to migrate towards the airflow duct, potentially resulting in condensation on one or both of the first and second transparent walls. Summary of the Invention

[0013] Therefore, the technical problem upon which this invention is based is to provide an electric cooking device configured to allow increased visibility of food present in the cooking chamber, the electric cooking device being simple, compact and economical in structure, while allowing use without risk to the user.

[0014] Therefore, the present invention relates to an electric cooking apparatus configured to cook food, and includes:

[0015] - Housing, the housing including a receiving and accommodating portion;

[0016] - A cooking container configured to occupy an insertion position and a removal position, wherein in the insertion position the cooking container is at least partially disposed within the receiving portion, and in the removal position the cooking container is at least partially removed from the receiving portion, the cooking container comprising:

[0017] o Cooking box, the cooking box being configured to hold food to be cooked and being accessible to a user when the cooking container is in the removal position, the cooking box and the housing being configured to define a cooking chamber when the cooking container is in the insertion position;

[0018] o Front panel, the front panel being configured to extend at least substantially toward the front of the cooking box;

[0019] o A first transparent wall, the first transparent wall being mounted on the cooking box and configured to at least partially close the first through hole provided on the cooking box;

[0020] o A second transparent wall, which is mounted on the front panel and configured to at least partially close the second through hole provided on the front panel;

[0021] o an airflow duct, the airflow duct being at least partially formed by the first transparent wall and the second transparent wall and configured to allow cooling airflow to flow between the first transparent wall and the second transparent wall;

The contact portion 12 is advantageously configured to extend around the periphery of the second through hole 8.2 and to contact the inner surface 13 of the front panel 6 when the current panel 6 is in use. This configuration of the invention allows fluid communication between the cooking chamber 5 and the airflow duct 9 to be avoided when the cooking chamber 4 is in the inserted position.

[0097] The contact portion 12 of the sealing element 11 is configured to deform upon contact with the inner surface 13 of the front panel 6. This configuration of the invention advantageously allows for compensation of gaps that may arise from the assembly between the cooking oven 4 and the front panel 6, and / or prevents sealing defects, for example, caused by the non-flatness of the inner surface 13.

[0098] like Figure 3 and Figure 4 As shown more specifically, the cooking box 4 includes a box body and a support frame 14 fixed to the box body and configured to support a first transparent wall 7.1.

[0099] According to a first embodiment of the invention, the electric cooking appliance 1 includes a coupling device 15 configured to allow a front panel 6 to be reversibly coupled to a cooking chamber 4. The coupling device 15 includes a locking member 15.1, such as a locking hole, disposed on the cooking chamber 4, and a locking element 15.2, such as a locking finger, disposed on the front panel 6. Advantageously, the locking element 15.2 is movable between a locking configuration and a release configuration, in which the locking element 15.2 is configured to cooperate with the locking member 15.1 to lock the front panel 6 onto the cooking chamber 4 and thus lock it in use, and in the release configuration, the locking element 15.2 is configured to release the locking member 15.1 to allow displacement of the front panel 6 relative to the cooking chamber 4. Advantageously, the locking element 15.2 is mounted to pivot about a pivot axis AP1, which is substantially horizontal when the electric cooking appliance 1 is placed on a horizontal surface and the cooking container 3 is in the inserted position.

[0100] Furthermore, the electric cooking appliance 1 includes an actuating member 15.3, which is mounted on the front panel 6 and pivotally integrated with the locking element 15.2. The actuating member 15.3 is configured to be accessible to the user when the current panel 6 is in the use configuration and the cooking container 3 is in the insertion position. The actuating member 15.3 can be actuated by the user and configured to control the displacement of the locking element 15.2 at least between the locking and releasing configurations. Advantageously, the actuating member 15.3 is configured to protrude at least partially relative to the outer surface of the front panel 6 when the current panel 6 is in the use configuration.

[0101] According to a first embodiment of the present invention, and as follows Figures 1 to 3 As shown more specifically, the electric cooking appliance 1 includes an air extraction unit 16 disposed within the housing 2 and configured to generate a cooling airflow in the airflow duct 9. The air extraction unit 16 is advantageously rotatably coupled to the drive unit 10.2, and the electric cooking appliance 1 is configured such that when the cooking chamber 4 is in the inserted position and the electric cooking appliance 1 is in hot air cooking mode, the cooling airflow flows in the airflow duct 9 and between the first transparent wall 7.1 and the second transparent wall 7.2.

[0102] The drive unit 10.2 is more specifically configured to drive the air extraction unit 16 to rotate about the second rotation axis A2. Advantageously, the first rotation axis A1 and the second rotation axis A2 are substantially parallel and, for example, coincident.

[0103] According to a first embodiment of the invention, the air extraction unit 16 is configured to extend below the drive unit 10.2 when the electric cooking appliance 1 is placed on a horizontal surface. This configuration of the air extraction unit 16 allows air to be blown to the drive unit 10.2 and thus generates a cooling airflow rising from the bottom of the electric cooking appliance 1, which is configured to pass through the airflow duct 9 before exiting the electric cooking appliance 1 from the top.

[0104] The airflow duct 9 includes at least one air inlet 17.1 and at least one air outlet 17.2 (see...). Figure 2 and Figure 3 The air inlet 17.1 and the air outlet 17.2 are respectively located on the lower and upper parts of the front panel 6.

[0105] In addition, the cooking container 3 includes at least one grip handle 18, which is integral with the front panel 6 and configured to extend at least partially toward the second transparent wall 7.2.

[0106] Figure 8 An electric cooking appliance 1 according to a second embodiment of the invention is shown. The main difference between this second embodiment and the first embodiment is that the air extraction unit 16 is configured to extend above the drive unit 10.2 when the electric cooking appliance 1 is placed on a horizontal surface. This configuration of the air extraction unit 16 allows air to be blown to the drive unit 10.2, thus generating a cooling airflow descending from the top of the electric cooking appliance 1. Therefore, the cooling airflow is configured to pass through the airflow duct 9 before exiting the electric cooking appliance 1.

[0107] According to a second embodiment of the present invention, at least one air inlet 17.1 and at least one air outlet 17.2 are respectively provided on the upper and lower parts of the front panel 6. Unlike the first embodiment of the present invention, when the air inlet 17.1 is provided on the upper part of the front panel 6 and the air outlet 17.2 is provided on the lower part of the panel, the generated cooling airflow descends from the upper end of the electric cooking appliance 1 to the lower end of the electric cooking appliance 1, and this cooling airflow flows through the airflow duct 9.

[0108] Of course, the present invention is by no means limited to the embodiments described and shown by way of example.
