DETAILED DESCRIPTION OF THE INVENTION

(9) With reference to the annexed drawings, reference numeral 1 designates as a whole an oven in accordance with the present invention.

(10) The oven 1 (FIG. 1) comprises, in the first place, a muffle 10. The muffle 10 has a box-like shape, preferably a parallelepiped shape, and has an opening for inserting/removing food to be warmed up or cooked.

(11) Preferably, the muffle 10 is associated with a door 20, which can be opened/closed to selectively allow access to the inside of the oven 1.

(12) The oven 1 is also provided with operating means 30 for heating an active zone A defined within the internal volume of said muffle 10.

(13) The door 20 allows, therefore, selective access to the active zone A as a function of its own operating position.

(14) The operating means 30 may comprise, by way of example, one or more electric resistors and one or more ventilation ducts. These features, which are per se known, will not be described any further.

(15) In accordance with the invention, the oven 1 comprises a camera 40.

(16) The camera 40 is configured for detecting one or more images X showing food positioned in the active zone A.

(17) Advantageously, the camera 40 is configured for detecting a plurality of images, so as to reproduce the evolution of the food during the warming/cooking process.

(18) In one embodiment (FIG. 2), the camera 40 is integrated into the door 20.

(19) In particular, the door 20 may comprise four layers S1-S4 of athermic material substantially transparent to visible light.

(20) The camera 40 can thus be housed in a recess 40a formed in one of said layers S1-S4.

(21) In the preferred embodiment, the camera 40 is housed in a recess formed in the third layer S3 (counting from the inside of the oven 1, i.e. from the active zone A).

(22) In this manner, the camera 40 will be sufficiently insulated, from a thermal viewpoint, from the inside of the oven 1, while at the same time being protected against any interference/tampering by careless or ill-intentioned users.

(23) Preferably, the camera 40 is substantially as thick as the layer in which it is housed.

(24) In one embodiment (FIG. 3), the camera 40 is mounted on a wall W belonging to the muffle 10.

(25) Preferably, the camera 40 is provided with a thermal protection element P, which is thermally insulating and at least partially transparent to the radiations detected by said camera 40.

(26) Advantageously, the camera 40 is associated with a transmission unit 50, which is configured for transmitting said one or more images detected by the camera 40 itself.

(27) The transmission unit 50 preferably uses a wireless technology; in particular, it performs a radio-frequency transmission (RF). By way of example, the transmission may rely on a wi-fi network, a Bluetooth connection, or a global network such as GSM/UMTS/LTE/LTE-A.

(28) The transmission unit 50 is configured for sending said one or more images X to an auxiliary device 60 configured for at least displaying said one or more images.

(29) In one embodiment (FIG. 4), the auxiliary device 60 comprises or is integrated into a television set or a digital monitor 100.

(30) In one embodiment (FIG. 5), the auxiliary device 60 is a Personal Digital Assistant 200, such as, for example, a palmtop, a smartphone, a tablet, etc.

(31) The user can thus verify, in the course of time, the degree of cooking of the food without having to gain access to the inside of the oven 1, and without necessarily having to be in proximity to the latter.

(32) Advantageously, the auxiliary device 60 is associated with a memory 70 storing one or more reference images Ref, preferably of the colorimetric type.

(33) Advantageously and in one embodiment (FIG. 6), the auxiliary device 60 is configured for displaying a comparison between said one or more images X transmitted by said transmission unit 50 and one or more of said reference images Ref.

(34) This option is particularly advantageous when recipes are preset in or downloaded to the auxiliary device 60.

(35) In this manner, the user is given an objective reference for evaluating the cooking condition of the food being prepared.

(36) The invention offers significant advantages.

(37) The oven according to the invention allows, in fact, a more reliable evaluation of the cooking condition of the food being prepared, without requiring the oven door to be opened.

(38) In addition, the invention allows the user to evaluate the conditions of the food positioned inside the oven, without even needing to be in proximity to the latter.
