Description

Steam generator with air fryer with steaming function and steaming and baking control method

Technical Field

The invention relates to the field of air fryer, in particular to a steam generator of an air fryer with a steaming function and a steaming and baking control method.

Background

The air is fried the pot at present and is all adopted the heating tube heating method, put the food that needs the heating inside the air is fried the pot, the air is fried pot internally mounted the heat-generating body, the heat that the heat-generating body produced heats the box through the convection current mode, receive each part heat conduction time's influence, the inside temperature of the air is fried the pot and is actually not even, the partial food temperature near being close to the heat-generating body is higher, and reverse side and inside temperature are lower, the inside temperature of the air is fried the pot and is extremely inhomogeneous, often cause the food of roast to burn out partially, also have partial food not to roast, especially the inside difficult roast of the great food of volume.

Certainly, an auxiliary air supply system is additionally arranged inside some air fryer to ensure that the temperature inside the air fryer is more uniform, and the problems of food burnout and insufficient baking are reduced. However, since the food baked by the user is different in size and shape, when the air fryer has more food or larger food, the air blowing system cannot reach the place (such as the inside of the food and the corner of the air fryer) where the food is burned out and the food is not baked.

In order to prevent the problems of burning and baking, the current air fryer can only observe the state of food in real time by a method of adding an observation window, if the air fryer is abnormally and immediately turned off, a box door is opened to turn over the food and bake the food again, and the operation is repeated until the food is baked, so that the baking mode needs to be looked after by a specially-assigned person, and especially, a non-professional ordinary user is difficult to bake the food with a good cooking effect, and the air fryer is inconvenient to use.

In addition, when the door is opened to turn over food, more heat can be dissipated, the heating efficiency is obviously reduced, and the baking time is prolonged.
