• fryer will be used to denote the cooking appliance, unless indicated.
• the fryer 1 comprises a shell 2 comprising an outline 3 which has a more or less parallelepiped shape, with a wall 4 arranged on the rear face 1a of the fryer 1, while the front face 1b of this fryer 1 allows the insertion of a tank 5 in the manner of a drawer in a cooking enclosure 6, the tank 5 being manipulated by means of a handling handle 7.

• a heating system 8 is arranged inside the shell 2, above the cooking enclosure 6.
• the shell 2 incorporates a control system intended to control the heating system. heater 8.
• a ventilation system 9 is arranged in the shell 2, above the heating system 8.
• This ventilation system 9 allows fresh air to be drawn through an upper part 10a d '' a grid 10 arranged on the wall 4, this air circulating in a suction duct 11 then through the heating system 8 in order to be heated and, finally, in the cooking chamber 6, before being discharged by a discharge circuit 12 opening into the lower part 10b of this grid 10.
• the various electrical components of the fryer 1, including in particular the heating system 8 and the ventilation system 9, are connected to an electrical supply circuit (not shown) which includes an electronic control card from (not shown). All these characteristics are already known on fryers currently on the market, which is why they will not be detailed; the art could for example refer to the hot air fryers developed by the applicant, in particular that sold under the name FRY DELIGHT ®.
• the fryer 1 is supplied electrically by means of an electrical supply cord, not illustrated in the figures, as is traditionally the case on electric cooking appliances.
• the power supply cord of the fryer 1 generally comprises a designed male plug which is plugged into a complementary female plug arranged on a wall; it is also conceivable that this electrical supply cord is connected directly to a cable outlet arranged on this wall wall, for other designs of cooking appliances.
• the end of the power supply cord is connected to the power supply circuit of the fryer via a connection terminal block, not shown in the figures.
• the fryer 1 comprises on the rear face 1a, an external housing 13 which is fixed to the wall 4, for example by screwing.
• This external housing 13 comprises a body 14 which extends perpendicular to the wall 4, along an axis X, and two branches 15, 16 arranged at the end 14a of the body 14. These two branches 15, 16 are arranged in opposition and extend by forming an arc in a direction opposite to the wall 4, as illustrated in these figures 1 and 2.
• This design of the external housing 13 has several advantages.
• the ends 15a, 16a branches 15, 16 abut against the vertical plane 18, which keeps the wall 4 of the fryer 1 away from said vertical plane 18.
• this maintenance of the wall 4 away from the vertical plane 18 avoids bringing the grid 10 too close to said vertical plane 18, so that the suction of fresh air and the discharge of hot air by this grid 10 are done correctly, without obstruction, during the operation of the ventilation system 9.
• the branches 15, 16 have flexibility, which makes it possible to slightly absorb shocks when the external housing 13 abruptly abuts against the vertical plane 18.
• the electrical supply cord can advantageously be wound around the body 14 when the fryer 1 is not in use or when the complementary female plug, to which the male plug of the power cord is connected electric, is positioned near the fryer 1.
• the body 14 preferably has an oval shape to reduce its overall width, but other shapes can be envisaged, for example a cylindrical shape. This oval shape facilitates the winding of the electrical supply cord around the body 14.
• the body 14 of the external housing 13 includes an orifice 19 which opens into a housing zone 20 arranged inside the external housing 13.
• This orifice 19 allows the passage of the end the power supply cord; in addition, the housing zone 20 is dimensioned to receive the connection terminal block ensuring the connection between the end of the electrical power supply cord and the electrical power supply circuit supplying the various electrical components of the fryer 1. For this, electrical wires from the electrical supply circuit pass through the wall 4 and the external housing 13 to connect to the electrical supply cord via the connection terminal block. By moving the connection terminal outside the shell 2, this considerably limits overheating at the end of the electrical supply cord and the connection terminal.

This allows reduce the thermal conduction from the wall 4 to the housing zone 20. This thermal conduction is moreover attenuated by the presence of air vents 22 on the body 14 which open into the insulation chamber 21 and pass through it so as to allow the circulation of natural air in it.
• the implementation of the external housing 13 having the above characteristics, thus overcomes the problem of overheating of the electrical supply cord and, moreover, ensures the unobstructed maintenance of the grid 10 for the proper functioning of the ventilation system 9 and avoids that the shell 2 - which heats - is in contact with the vertical plane 18.
• the implementation of such an external box 13 can be envisaged on the hulls of other cooking appliances than the fryer 1, without leaving the part of the invention, by adapting the position of the external housing according to the configurations of these cooking appliances.
