In the configuration in which the deep fryer 1 is to be used, the deep fryer tank 2 is arranged in the outer housing 4. The outer peripheral rim 20 rests on the upper edge 41.

[0036] In the exemplary embodiment illustrated in FIG. 1, the electric deep fryer 1 comprises a cooking basket 5 and a lid 6. The lid 6 can be used for cooking or for storage.

[0037] In the exemplary embodiment illustrated in FIG. 1, the electric deep fryer 1 comprises a drain pan 7 configured to collect the fat contained in the deep fryer tank 2. For this purpose the deep fryer tank 2 comprises a drain mechanism 21, which can be seen more clearly in FIGS. 3 and 5.

[0038] The deep fryer tank 2 is made of deep-drawn metal material. The deep fryer tank 2 may in particular be made of stainless steel. As a variant, the deep fryer tank 2 may in particular be made of enameled steel or aluminum.

[0039] The deep fryer tank 2 may comprise level markings 27. The deep fryer tank 2 has, for example, a thickness of about 0.6 mm. The tolerance of the thickness of the deep fryer tank 2 is preferably ±0.1 mm.

[0040] As can be more clearly seen in FIGS. 2 through 5, the deep fryer tank 2 has a bottom 22 and several sides 23 connected to the bottom 22 by curves 24. Adjacent sides 23 are connected to each other by other curves 25.

[0041] In the deep fryer tank 2 according to the invention, at least one of the sides 23 has a rigidifying lateral indentation 8 forming a lateral recess extending in one direction, as well as another rigidifying lateral indentation 9 forming another lateral recess extending in another direction, and said rigidifying lateral indentation 8 intersects with said other rigidifying lateral indentation 9.

[0042] The level markings 27 may extend into one of the rigidifying lateral indentations 8 and/or into one of the other rigidifying lateral indentations 9. However, the level markings 27 are preferably made on flat surfaces. If desired, the level markings 27 extend exclusively into one of the rigidifying lateral indentations 8 and/or into one of the other rigidifying lateral indentations 9.

[0043] More particularly in the exemplary embodiment illustrated in the figures, all of the sides 23 have at least one of the rigidifying lateral indentations 8 and at least one of the other rigidifying lateral indentations 9. As can be more clearly seen in FIGS. 4 and 5, all of the rigidifying lateral indentations 8 and all of the other rigidifying lateral indentations 9 are surrounded by non-indented portions of the sides 23.

[0044] More particularly in the exemplary embodiment illustrated in the figures, the direction and the other direction are perpendicular. The direction extends perpendicular to the bottom 22 and the other direction extends parallel to the bottom 22.

[0045] More particularly in the exemplary embodiment illustrated in the figures, the deep fryer tank 2 is parallelepipedal. In other words, the deep fryer tank 2 has four sides 23 opposite each other in pairs. Apart from the rigidifying lateral indentations 8 and the other rigidifying lateral indentations 9, the sides 23 may have a flat geometry. As can be clearly seen in FIGS. 2 through 5, the rigidifying lateral indentations 8 and the other rigidifying lateral indentations 9 extend into the deep fryer tank 2. The rigidifying lateral indentations 8 and the other rigidifying lateral indentations 9 extend exclusively along the sides 23.

[0046] More particularly, in the exemplary embodiment illustrated in the figures, all of the sides 23 have two other rigidifying lateral indentations 9 extending parallel to the bottom 22. The sides 23 comprise two first opposite sides 23 that have two rigidifying lateral indentations 8 extending perpendicular to the bottom 22. One of the two other rigidifying lateral indentations 9 of said two opposite sides 23 has a greater height between the rigidifying lateral indentations 8 than on the outside of the rigidifying lateral indentations 8. The sides 23 comprise two second opposite sides 23 that have a single rigidifying lateral indentation 8 extending perpendicular to the bottom 22. On a same side, the other rigidifying lateral indentations 9 extend perpendicular to the rigidifying lateral indentation 8 or to the rigidifying lateral indentations 8.

[0047] More particularly, in the exemplary embodiment illustrated in the figures, the bottom 22 has lower rigidifying indentations 28 intersecting with other lower rigidifying indentations 29. Each of the lower rigidifying indentations 28 forms a lower recess extending in a first direction. Each of the other lower rigidifying indentations 29 forms another lower recess extending in a second direction. The first direction and the second direction are perpendicular. The first direction and the second direction each extend parallel or perpendicular to each of the sides. The lower rigidifying indentations 28 and the other lower rigidifying indentations 29 extend into the deep fryer tank 2. As can be more clearly seen in FIGS. 4 and 5, the bottom 22 has four lower rigidifying indentations 28 each intersecting two other lower rigidifying indentations 29.

[0048] As a variant, the direction and the other direction are not necessarily perpendicular. The direction and the other direction may in particular have an angle comprised between 60° and 120°, and preferably comprised between 80° and 100°.

[0049] As a variant, the other direction does not necessarily extend parallel to the bottom 22.

[0050] As a variant, the direction does not necessarily extend perpendicular to the bottom 22.

[0051] As a variant, the direction and the other direction are not necessarily identical for all of the sides 23.

[0052] As a variant, not all of the rigidifying lateral indentations 8 and not all of the other rigidifying lateral indentations 9 necessarily extend into the deep fryer tank 2. In particular, at least one of the rigidifying lateral indentations 8 and/or at least one of the other rigidifying lateral indentations 9 may extend outward from the deep fryer tank 2.

[0053] As a variant, not all of the rigidifying lateral indentations 8 and not all of the other rigidifying lateral indentations 9 are necessarily surrounded by non-indented portions of the sides 23.

[0054] As a variant, not all of the rigidifying lateral indentations 8 and not all of the other rigidifying lateral indentations 9 necessarily extend exclusively along the sides 23. At least one of the rigidifying lateral indentations 8 and/or at least one of the other rigidifying lateral indentations 9 may in particular extend to at least one of the curves 24 and/or one of the other curves 25.

[0055] As a variant, not all of the sides 23 necessarily have at least one of the rigidifying lateral indentations 8 and at least one of the other rigidifying lateral indentations 9.

[0056] As a variant, at least one of the sides 23 may have at least one of the rigidifying lateral indentations 8 and at least one of the other rigidifying lateral indentations 9.

[0057] As a variant, the bottom 22 does not necessarily have at least one lower rigidifying indentation 28 forming a lower recess extending in a first direction and at least one other lower rigidifying indentation 29 forming another lower recess extending in a second direction, with said at least one lower rigidifying indentation 28 intersecting said at least one other lower rigidifying indentation 29.

[0058] The deep fryer tank 2 is used like a conventional deep fryer tank. When the frying bath contained in the deep fryer tank 2 is heating up or cooling down, the rigidifying lateral indentations 8 and the other rigidifying lateral indentations 9 rigidify the sides 23 of the deep fryer tank 2 and prevent the phenomena of popping or sudden deformation of the sides 23 caused by the thermal expansion of the material of the deep fryer tank 2. The lower rigidifying indentations 28 and the other lower rigidifying indentations 29 rigidify the bottom 22 of the deep fryer tank 2 and prevent the phenomena of popping or sudden deformation of the bottom 22 caused by the thermal expansion of the material of the deep fryer tank 2. The safety and comfortable use of the deep fryer tank 2 are improved.

[0059] The present invention is by no means limited to the exemplary embodiment described and to its variants, but encompasses numerous modifications within the scope of the claims.
