At least one side has at least one other rigidifying lateral indentation forming another lateral recess extending in another direction, and the at least one rigidifying lateral indentation intersects the at least one other rigidifying lateral indentation. An electric deep fryer comprises a deep fryer tank of the aforementioned type. ## Claims ### Claim 1 A deep fryer tank comprising a deep-drawn metal material, the deep fryer tank comprising a bottom and at least first and second sides connected to the bottom by curves, at least one of the first and second sides having at least one first lateral indentation forming a first lateral recess extending in a first direction, wherein the at least one of the first and second sides has at least one second lateral indentation forming a second lateral recess extending in a second direction, wherein the at least one first lateral indentation intersects the at least one second lateral indentation, and wherein the bottom extends continuously along a plane across an entire length and width of the deep fryer tank. ### Claim 2 (depends on 1) The deep fryer tank according to claim 1, wherein the at least one first lateral indentation and the at least one second lateral indentation extend into the deep fryer tank. ### Claim 3 (depends on 1) The deep fryer tank according to claim 1, wherein the at least one first lateral indentation and the at least one second lateral indentation extend exclusively along the at least first and second sides. ### Claim 4 (depends on 1) The deep fryer tank according to claim 1, wherein the at least one first lateral indentation and the at least one second lateral indentation are surrounded by non-indented portions of the at least first and second sides. ### Claim 5 (depends on 1) The deep fryer tank according to claim 1, wherein the first direction and the second direction have an angle between 60° and 120°. ### Claim 6 (depends on 1) The deep fryer tank according to claim 1, wherein the first direction and the second direction are perpendicular to each other. ### Claim 7 (depends on 1) The deep fryer tank according to claim 1, wherein the second direction extends parallel to the bottom. ### Claim 8 (depends on 1) The deep fryer tank according to claim 1, wherein the first direction extends perpendicular to the bottom. ### Claim 9 (depends on 1) The deep fryer tank according to claim 1, wherein all of the at least first and second sides have said at least one first lateral indentation and said at least one second lateral indentation. ### Claim 10 (depends on 1) The deep fryer tank according to claim 1, wherein all of the at least first and second sides have the at least one second lateral indentation and a second second lateral indentation extending parallel to the bottom. ### Claim 11 (depends on 1) The deep fryer tank according to claim 1, wherein the deep fryer tank is parallelepipedal. ### Claim 12 (depends on 1) The deep fryer tank according to claim 1, wherein the at least first and second sides are opposite each other and have the at least one first and a second first lateral indentations extending perpendicular to the bottom. ### Claim 13 (depends on 12) The deep fryer tank according to claim 12, wherein one of the at least one second and the second second lateral indentations of the first and second sides has a greater height between the at least one first lateral indentations than on an outside of the at least one first lateral indentations. ### Claim 14 (depends on 1) The deep fryer tank according to claim 1, wherein the bottom has at least one first lower indentation forming a first lower recess extending in a third direction and at least one second lower indentation forming a second lower recess extending in a fourth direction, said at least one first lower indentation intersecting said at least one second lower indentation. ### Claim 15 (depends on 1) The deep fryer tank according to claim 1, wherein the deep drawn material comprises stainless steel. ### Claim 16 (depends on 1) An electric deep fryer comprising the deep fryer tank according to claim 1 and an electric heating device. ### Claim 17 (depends on 16) The electric deep fryer according to claim 16, wherein the electric heating device comprises an electric immersion heating device configured to be immersed in a frying bath contained in the deep fryer tank. ### Claim 18 (depends on 16) The electric deep fryer according to claim 16, wherein the electric heating device comprises an electric induction heating device configured to heat the deep fryer tank by induction. ### Claim 19 (depends on 16) The electric deep fryer according to claim 16, wherein the deep fryer comprises an outer housing with an upper opening and the deep fryer tank is arranged in the outer housing. ### Claim 20 (depends on 19) The electric deep fryer according to claim 19, wherein the deep fryer tank comprises an outer peripheral rim, the outer housing comprises an upper edge, and the outer peripheral rim rests on the upper edge. ### Claim 21 A deep fryer tank comprising a deep-drawn metal material, the deep fryer tank comprising a bottom and at least first and second sides connected to the bottom by curves, at least one of the first and second sides having at least one first lateral indentation forming a first lateral recess extending in a first direction, wherein the at least one of the first and second sides has at least one second lateral indentation forming a second lateral recess extending in a second direction, wherein the at least one first lateral indentation intersects the at least one second lateral indentation, and wherein the bottom has at least one first lower indentation forming a first lower recess extending in a first direction and at least one second lower indentation forming a second lower recess extending in a second direction, said at least one first lower indentation intersecting said at least one second lower indentation, wherein the bottom extends perpendicular to the first and second sides. ### Claim 22 A deep fryer tank comprising a deep-drawn metal material, the deep fryer tank comprising a bottom and at least first and second sides connected to the bottom by curves, at least one of the first and second sides having at least one first lateral indentation forming a first lateral recess extending in a first direction, wherein the at least one of the first and second sides has at least one second lateral indentation forming a second lateral recess extending in a second direction, wherein the at least one first lateral indentation intersects the at least one second lateral indentation, and wherein the bottom has at least one first lower indentation forming a first lower recess extending in a first direction and at least one second lower indentation forming a second lower recess extending in a second direction, said at least one first lower indentation intersecting said at least one second lower indentation, wherein the bottom faces toward and is opposite an upper opening of the deep fryer tank.
