[0036] According to one embodiment of the invention, the fixing device is a bayonet fixing device. Such a configuration of the fixing device allows quick and easy assembly and disassembly of the fan; the assembly and disassembly of the fan being carried out by a user without the use of tools.

[0037] According to one embodiment of the invention, the heating device is removably attached to the lid, such that the heating device is configured to occupy a cooking configuration in which the heating device is secured to the lid, and a cleaning configuration in which the heating device is detached from the lid. Such a configuration of the heating device makes it easier to access the fan, in particular for the purpose of dismantling it, when the fan is attached to the lid.

[0038] According to one embodiment of the invention, the electric cooking appliance comprises an electrical power supply portion provided on the cover and configured to electrically power the heating device, and an electromechanical connection device configured to reversibly assemble the heating device to the electrical power supply portion.

[0039] According to one embodiment of the invention, the power supply portion is configured to be electrically connected to a power supply source.

[0040] According to one embodiment of the invention, the electromechanical connection device is configured to maintain the heating device in a cooking configuration in which the heating device is integral with the electrical supply portion, while ensuring electrical conductivity between the electrical supply portion and the heating device.

[0041] According to one embodiment of the invention, the electrical power supply part is integral and irremovable relative to the cover.

[0042] According to one embodiment of the invention, the electromechanical connection device comprises a male electromechanical connection part and a male electromechanical connection part. female electromechanical connection configured to cooperate by form fit with the male electromechanical connection portion, the male electromechanical connection portion and the female electromechanical connection portion being provided respectively on one and the other of the power supply portion or the heating device.

[0044] According to one embodiment of the invention, the passage opening is configured to allow passage of the fan, for example from the use configuration to the cleaning configuration, according to a translational movement substantially parallel to the axis of rotation.

[0045] According to one embodiment of the invention, the passage opening is configured to allow passage of the fan from the cleaning configuration to the use configuration.

[0046] According to one embodiment of the invention, the heating device comprises a heating part, the fan and the heating part being spaced apart from each other by a separation distance measured along the axis of rotation, the separation distance being greater than a mounting clearance between the fan and the cover, the mounting clearance being configured to allow movement of the fan relative to the cover according to a movement of movement which is substantially parallel to the axis of rotation.

[0047] According to one embodiment of the invention, the heating portion is configured to extend below the fan when the fan is attached to the cover.

[0048] According to one embodiment of the invention, the heating device delimits at least in part a lateral clearance configured to allow movement of the fan transversely to the axis of rotation when the fan is detached from the cover. In other words, the lateral clearance is configured to allow the passage of the fan as well as the hand of a user in order to install and remove the fan.

[0049] According to one embodiment of the invention, the electric cooking appliance comprises a measuring device configured to measure a power supply parameter of the electric motor, for example the power supply current of the electric motor, during an operating cycle of the drive unit, and the control unit is configured to detect the presence or absence of the fan, i.e. whether the fan is attached to the cover or not, depending on the measured value of the power supply parameter and to prohibit operation of the heating device in the absence of the fan.

Since the motor torque of the electric motor is proportional to a power supply parameter of the electric motor, such as the power supply current of the electric motor, monitoring such a power supply parameter by the control unit makes it possible to easily detect a variation in the motor torque of the electric motor during an operating cycle of the electric motor, and thus to detect in particular the absence of a fan when the power supply parameter is relatively low.Thus, the electric cooking appliance according to the present invention makes it possible to automatically detect the presence or absence of the fan without the addition of a specific sensor dedicated to this function. The same logic of electrical power consumption can be applied by the control unit in order to detect the presence (or absence) of the heating device.

The upper cover portion 8.A and the lower cover portion 8.B are irremovable from each other. By irremovable, it is meant that the upper and lower cover portions 8.A, 8.B are not removable by a user during standard use of the electric cooking appliance 1.

[0066] The electric cooking appliance 1 further comprises a hot air cooking system 10 arranged at least partly in the cover 8 and configured to generate a flow of hot air on food received in the cooking tank 5 when the electric cooking appliance 1 is in the hot air cooking mode.

More specifically, the fan 11 is configured to generate an airflow over food received in the cooking tank 5.

[0068] The hot air cooking system 10 further comprises a heating device 13 mechanically connected to the cover 8 and configured to heat the air flow generated by the fan 11.

[0069] According to the embodiment of the invention shown in Figures 1 and 2, the heating device 13 comprises an electrical heating resistor, and is configured to be located at least partly opposite the cooking tank 5, and in particular opposite the access opening 6, when the cover 8 occupies the closed position. More particularly, the heating device 13 comprises a heating portion 14 configured to extend below the fan 11 when the fan 11 is fixed to the cover 8. Advantageously, the heating device 13 delimits, with the cover 8, a lateral clearance 15 configured to allow movement of the fan 11 transversely to the axis of rotation A2 when the fan 11 is detached from the cover 8.In other words, the lateral clearance 15 is configured to allow the passage of the fan 11 as well as a user's hand in order to install and remove the fan 11 for example.

[0070] More particularly, and as shown in [Fig. 1], the fan 11 is configured to extend substantially opposite the cooking tank 5, and further particularly to extend opposite the access opening 6, when the fan 11 is fixed to the cover 8 and the cover 8 is in the closed position. The fan 11 and the heating part 14 are configured to be spaced apart from each other by a separation distance D measured along the axis of rotation A2, the separation distance D being greater than a mounting clearance between the fan 11 and the cover 8, the mounting clearance being configured to allow movement of the fan 11 relative to the cover 8 according to a displacement movement which is substantially parallel to the axis of rotation A2.

[0071] According to the first embodiment of the invention shown in Figures 1 and 2, the drive unit 12 comprises a drive motor 12.1 housed in the cover 8, and a drive shaft 12.2 rotatably coupled to the drive motor 12.1 such that the fan 11 is configured to occupy a use configuration (see [Fig.l]) in which the fan 11 is rotationally secured to the drive shaft 12.2, and a cleaning configuration (see [Fig.2]) in which the fan 11 is detached from the drive shaft 12.2 and is capable of being removed from a space formed between the lower face 9 and the heating device 13. The drive shaft 12.2 extends along the axis of rotation A2 and through a passage orifice provided on the cover 8 so as to project from the lower face of the cover 8.

[0072] Advantageously, the electric cooking appliance 1 comprises a fixing device 17 comprising a first fixing part 17.1 fixed to the drive shaft 12.2, and for example to a lower end portion of the drive shaft 12.2, and a second fixing part 17.2 fixed to the fan 11 and configured to be reversibly assembled to the first fixing part 17.1. According to one embodiment of the invention, one of the first fixing part 17.1 and the second fixing part 17.2 is a male fixing part and the other of the first fixing part 17.1 and the second fixing part 17.2 is a female fixing part, however a bayonet type assembly or an equivalent mechanical assembly may nevertheless be technical alternatives that can be envisaged.

[0073] According to the embodiment of the invention shown in Figures 1 and 2, the electric cooking appliance 1 comprises a measuring device 16 configured to measure a power supply parameter of the electric motor 12.2, for example the power supply current of the electric motor 12.2, during an operating cycle of the drive unit 12. Advantageously, the control unit 2 is configured to detect the presence or absence of the fan 11, i.e. whether the fan 11 is attached to the cover 8 or not, as a function of the measured value of the power supply parameter. According to the embodiment of the invention, the control unit 2 is configured to trigger at least one action of the electric cooking appliance 1, and for example prevent operation of the electric cooking appliance 1 according to the hot air cooking mode, when the absence of the fan 11 has been detected by the control unit 2.

[0074] The electrical power consumed by the drive motor 12.1 is relatively low when the fan 11 is not attached to the fan 11. On the contrary, when the fan 11 is present, the necessary motor torque, and therefore the electrical power consumed, is higher, and varies according to the rotation speed of the fan 11. The motor torque of the drive motor 12.1 being proportional to a power supply parameter of the drive motor 12.1, such as the power supply current of the drive motor 12.1, the monitoring of such a power supply parameter by the control unit 2 makes it possible to easily detect a variation in the motor torque of the drive motor 12.1 during an operating cycle of the drive motor 12.1, and thus to detect in particular the absence of the fan 11 when the power supply parameter is relatively low.Thus, the electric cooking appliance 1 according to the present invention makes it possible to automatically detect the presence or absence of the fan 11 without the addition of a specific sensor dedicated to this function.

[0075] [Fig. 3] shows an electric cooking appliance 1 according to a second embodiment of the invention which differs from the first embodiment of the invention essentially in that the heating device 13 is removably attached to the cover 8, such that the heating device 13 is configured to occupy a cooking configuration in which the heating device 13 is secured to the cover 8, and a cleaning configuration (shown in [Fig. 3]) in which the heating device 13 is detached from the cover 8. Such a configuration of the heating device 13 makes it easier to access the fan 11, in particular for the purpose of dismantling it, when the fan 11 is attached to the cover 8.

[0076] More specifically, the electric cooking appliance 1 comprises a power supply portion 18 provided on the cover 8 and configured to electrically supply the heating device 13, and an electromechanical connection device 19 configured to reversibly assemble the heating device 13 to the power supply portion 18. In order to ensure the operation of the heating device 13, the power supply portion 18 is configured to be electrically connected to a power source.

[0077] Advantageously, the electromechanical connection device 19 is configured to maintain the heating device 13 in a cooking configuration in which the heating device 13 is integral with the electrical supply part 18, while ensuring electrical conductivity between the supply part electrical 18 and the heating device 13. The electromechanical connection device 19 may, for example, comprise a male electromechanical connection part and a female electromechanical connection part configured to cooperate by form-fitting with the male electromechanical connection part; the male electromechanical connection part and the female electromechanical connection part being provided respectively on one and the other of the electrical supply part 18 or the heating device 13.

[0078] According to the embodiment of the invention shown in [Fig. 3], the control unit 2 is further configured to monitor a variation in a power supply parameter of the electric heating resistor during an operating cycle of the heating device 13, and to trigger at least one action of the electric cooking appliance 1 as a function of the variation in the power supply parameter of the electric heating resistor. Such a configuration of the electric cooking appliance 1 makes it possible, for example, to detect whether the electric heating resistor is attached to the cover 8 and is capable of heating the air flow generated by the fan 11 and is capable of cooking the food to be cooked present inside the cooking tank 5.

[0079] [Fig. 4] represents an electric cooking appliance 1 according to a third embodiment of the invention which differs from the first embodiment of the invention essentially in that the heating device 13 delimits a passage opening 20 through which the fan 11 is able to be moved during an operation of dismantling the fan 11. The passage opening 20 is configured to allow passage of the fan 11, for example from the use configuration to the cleaning configuration, according to a translational movement substantially parallel to the axis of rotation A2. Conversely, the passage opening 20 is configured to allow passage of the fan 11 from the cleaning configuration to the use configuration. Such a configuration of the invention further simplifies the handling of the fan 11 by the user.Advantageously, the passage opening 20 extends coaxially with the axis of rotation A2.

[0080] According to an embodiment of the invention not shown in the figures, the heating device 13 is mounted to move between at least one operating position and a cleaning position in which the heating device 13 allows free access to the fan 11. More particularly, the electric cooking appliance 1 comprises a pivot connection configured to allow pivoting of the heating device 13 around a secondary pivot axis A3 at least between the operating position and the cleaning position. Advantageously, the secondary pivot axis A3 is substantially horizontal when the housing 3 rests on a horizontal surface.

[0081] Of course, the present invention is in no way limited to the embodiments described and illustrated which have been given only as examples. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
