[0019] Such asFigures 1-3 As shown, a filter assembly for an electric fryer comprises a pot body 1 and an inner pot 2 fixedly mounted in the pot body, wherein the inner pot has a frying tank with an upper opening, and an electric heater 3 is placed at the bottom of the frying tank;

[0020] The outer wall of the pot body is spaced apart from the inner wall of the inner pot;

[0021] An oil outlet is provided at the lower end of the inner pot, and the oil outlet is connected to the oil outlet pipe 5 through the oil nozzle 4 downward. An oil outlet solenoid valve 6 is installed at the lower end of the oil nozzle. The oil outlet pipe is connected to the filter cartridge 7 through a lower return pipe 10. A filter screen is fixed in the filter cartridge, and the filter cartridge is connected to the oil inlet pipe 9 through an upper return pipe 8. The upper return pipe is located above the filter screen. The oil inlet pipe is located in the inner pot and has an oil inlet provided downward. A lower circulating oil pump 11 and an upper circulating oil pump 12 are respectively installed on the lower return pipe and the upper return pipe.

[0022] In this way, cooking oil is poured into the inner pot, the electric heater heats the cooking oil, and the food is placed in the frying basket, which is then placed in the inner pot, or the food is placed directly in the inner pot to remove the oil residue. When impurities and debris need to be cleaned, the upper and lower circulation oil pumps are started, and the oil outlet solenoid valve is opened, driving the cooking oil from the oil outlet, the oil nozzle, the oil outlet pipe, and the lower return pipe to the filter barrel. The cooking oil flows upward, and the filter screen blocks and filters impurities and debris.
