Air fryer with steaming function and method for controlling air fryer with steaming function

A method for controlling an air fryer with a steaming function,

• wherein the air fryer comprises a cooking chamber and a water tank,
• the cooking chamber and the water tank are arranged inside a housing,
• the air fryer is further provided therein with a control unit and a steam generator,
• a heating chamber is provided in the steam generator,
• the heating chamber in the steam generator is connected to the water tank via a water pump,
• high-temperature steam generated in the heating chamber of the steam generator is introduced into the cooking chamber,
• a chamber temperature sensor is arranged in the cooking chamber,
• each of the chamber temperature sensor, the steam generator and the water pump is electrically connected to the control unit,
• the cooking chamber has a volume of 5 to 10 L,
• wherein the water tank comprises a main water tank and a secondary water tank mounted at a lower end of the main water tank, wherein
• the main water tank is detachably mounted onto the secondary water tank, the main water tank has a volume of 500 to 1,500 mL,
• the secondary water tank communicates with the main water tank, the water pump is connected to the secondary water tank,
• a water level sensor is mounted at a bottom of an inner side of the secondary water tank, and
• the water level sensor is electrically connected to the control unit;
• wherein a one-way valve is mounted at a steam outlet end of the heating chamber of the steam generator, wherein a steam outlet end of the one-way valve is connected to a steam adapter via an adapting member, one end of the steam adapter leads into the cooking chamber, and a plurality of corresponding steam transmission holes are arranged side by side in both the adapting member and the steam adapter;
• wherein the method for controlling the air fryer comprises steps of:
• S1:
• filling the water tank with water for generating steam, and controlling, before generating the steam, the heating chamber of the steam generator to be preheated, and causing the control unit to automatically activate the water pump connected to a water pipe to inject water in the water tank, from the water tank into the steam generator, through a connecting pipeline, when a temperature sensor detects that a temperature of the heating chamber increases to a predetermined temperature required for vaporization of a liquid;
• and
• S2:
• causing a temperature of the water in the heating chamber to be rapidly increased to a vaporization temperature and the water to be vaporized into water steam, when a volume of the water steam expands violently and generating a predetermined pressure to push the one-way valve, discharging the water steam at high temperature and high pressure to the cooking chamber through a steam pipeline to heat food.
