Definitions

• the present invention relates to electric fryers which comprise, in a housing, a steel tank, fixed or removable, which is filled with frying oil over a given height and defined from the highest point of the bottom of the tank. , and electric heating means arranged under the tank and in thermal relation with the latter.
• the invention therefore proposes to produce in a simple and efficient manner an electric fryer with a steel tank, of the type described above, which perfectly meets the requirements of this safety standard.
• the bottom of the tank comprises at least one boss rising inside the tank over a predetermined height relative to said bottom and having a top constituting said point the top of the bottom of the tank.
• this boss makes it possible to artificially raise the highest point of the bottom of the tank, which point is now formed by the top of the boss above which the oil must reach a height of one centimeter as required by the standard, and therefore significantly increases the volume of oil in the tank.
• the boss is located in the center of the bottom of the tank.
• the electric fryer for example of rectangular cross section, comprises an external housing 1 shown here diagrammatically in phantom, which delimits a closed enclosure thanks to a cover (not shown), and inside which is fixed or removable a cooking vessel 2, preferably also rectangular.
• the cooking tank 2 comprises a flat bottom 4 having an external 4a and internal 4b face, and side walls rising from the bottom 4 and delimiting with the latter the internal volume of the tank.
• the cooking tank 2 is made of a steel capable of being covered with a heat-resistant coating 5, such as, for example, enamel, both on the internal faces 2a and on the external faces 2b of the tank 2, in order to facilitate the cleaning of the tank and to avoid the adhesion of food on the interior surface of the tank.
• the steel tank 2 is produced by stamping a sheet metal plate and is then covered internally and externally with enamel in this example.
• electrical heating means designated by the general reference 6, which are arranged under the bottom 4 of the enamelled steel tank 2 and which are in thermal relation with the tank 2.
• the tank 2 is removably mounted in the housing 1 and the external face 4a of the enamelled bottom 4 of the tank rests flat on the electric heating means 6 comprising an armored heating resistor 8 extending flat and advantageously having a serpentine shape suitable for promoting its thermal contact over the entire length and width of the bottom 4 of the rectangular tank 2 in this example.
• the enamelled steel tank 2 can also be mounted fixed in the housing 1 and, in this case, the armored heating resistance 8 is attached to the external face 4a of the bottom 4 of the tank by any suitable fixing means, for example by welding.
• the screened resistor 8 could be replaced by a screen-printed resistance, also attached to the external face 4a of the bottom 4 of the tank, without thereby departing from the scope of the invention.
• the bottom 4 of the steel tank 2 comprises at least one. boss 10, in this case only one, which rises inside the tank over a predetermined height, denoted hl, relative to the very bottom 4 of the tank, and which has an apex 10a defining in itself the point the top of the bottom 4 of the tank 2.
• the boss 10 comes from stamping with the steel tank 2 and has in cross section a preferential trapezoidal shape whose small base constitutes the top 10a of the boss 10 and extends parallel, at a distance hl , of the flat part of the bottom 4 of the tank.
• the boss 10 is formed at the center of the bottom 4 of the enamelled steel tank 2, and its height hl is of the order of 5 millimeters.
• the boss 10 forms a groove for receiving the armored resistance 8.
• the boss 10 artificially rises the center of the bottom 4 of the enamelled steel tank and, in accordance with the safety standard, the tank 2 is then filled with frying oil 12 over a height h equal to one centimeter at the above the highest point of the bottom of the tank and which is therefore defined by the top 10a of the boss 10, so that the oil reaches the level hl + h, of the order of 1.5 centimeters, relative to the flat part of the bottom of the tank 2.
• filling the oil in tank 2 at the level hl + h advantageously provides a greater volume of oil in the tank, compared to the same enamelled steel tank but with a uniformly flat bottom, so that, following the operation of the fryer with this volume of oil, the thermal energy is dissipated in a relatively homogeneous manner on the bottom and the side walls of the enamelled steel tank 2, as well as in the oil 12, the temperature of which does not exceed 280 ° C., as required by the safety standard.
