A domestic deep fat fryer comprising, in a housing (1), a vessel (2) adapted to contain a cooking bath (3). An electric heating resistance (4) heats the cooking bath. A thermal regulator (6) of high thermal inertia is mounted in series with the heating resistance and operates over a predetermined range of switching temperature. The fryer moreover comprises a thermostatic safety switch (8) mounted in series with the electric heating resistance and operating at a fixed switching temperature higher than the maximum temperature of the temperature range of the thermal regulator (6). This thermostatic safety switch has a thermal inertia less than that of the regulator (6) so as to detect abnormally rapid temperature increases and to cut off the electrical supply in such case to the electric heating resistance.
