Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a cooking device. Background Art

[0002] An air fryer is a food heating technology that uses high-speed hot air to heat the food. The heating tube in the pot generates high temperature to generate hot air, and then a fan blows the high-temperature air into the pot to heat the food. The hot air circulates in a closed space and uses the fat in the food itself to fry the food, thereby dehydrating the food and making the surface golden and crispy, achieving the effect of frying.

[0003] The existing Chinese patent application number CN202122532504.6 discloses a double-pot air fryer. The double-pot air fryer comprises a pot rack, a pot rack cover, an inner pot, a mainboard box and an outer shell. The outer shell is hollow and a through hole is provided on one side plate. An upper air inlet hole is provided on the top plate of the outer shell. There are two pot racks, which are fixed by a connecting piece and are located in the outer shell, and the upper ends and one side wall of the pot racks are open. The pot rack cover is used to close the upper ends of the two pot racks, and the center of the pot racks is pressed downward to form a storage cavity. The lower end of the storage cavity is in contact with the connecting piece. A mainboard box is provided in the storage cavity. The mainboard box is hollow inside and a row of air inlet holes is provided on the bottom surface. The air inlet holes cut downward through the mainboard box, the storage cavity, the connecting piece to the bottom plate of the outer shell to form lower air inlet holes. The pot rack covers on both sides of the storage cavity are also provided with heating components opposite to the pot racks. At the same time, air outlets are also provided on the side walls of the pot rack cover, and the air outlets are opposite to the air outlet I provided on the outer shell. The inner pot passes through the plug-in hole and the side wall opening of the pot rack to the pot rack, and the pot handle of the inner pot is located outside the outer shell.

[0004] In existing multi-pot cooking devices, each pot is provided with an air outlet structure to discharge excess hot air in the pot through the air outlet. However, multiple air outlet structures will increase the difficulty of manufacturing the cooking device and also increase the manufacturing cost. In addition, there will be multiple places on the cooking device to discharge hot air, which greatly increases the possibility of users being harmed by hot air when using the cooking device, thereby reducing the safety of using the cooking device.
