Description

Air fryer

Technical Field

The utility model relates to the technical field of cooking appliances, in particular to an air fryer.

Background

As technology advances and consumer demand increases, the number of baking pans in an air fryer begins to be no longer limited to one, and two or more baking pan designs in a longitudinal or transverse arrangement begin to appear on the market. For a conventional single-baking pan structure, the current hot air component is usually designed at the upper position of the baking pan and adopts a circular axial flow fan to realize hot air circulation to bake food, and one common problem is that the top surface of the food is baked fully and the bottom surface receives lower heat, so that the problem of uneven heating is generated.

Meanwhile, if two kinds of foods with different temperatures and times are to be baked at the same time, a separately controlled baking pot needs to be added on the air fryer. The existing double-pot air fryers in the market are basically arranged left and right, namely, two air fryers are made into a connected body through structural design, and in order to give consideration to the appearance, the pot body is basically designed into a slender cuboid, and the normal circular axial flow fan blades are difficult to evenly supply air;

Besides the double-pot structure which is arranged left and right, the double-pot structure which is arranged up and down is also arranged up and down, and for the double-pot structure which is arranged up and down, hot air channels are basically arranged on the side face, one is that the side wall of the roasting pot is directly blown by an axial flow fan, through holes are fully formed in the periphery and the lower part of the side wall of the roasting pot, and obviously, for the slender cuboid roasting pot, on one hand, the axial flow fan blades can only directly blow partial areas for air return, because the air return is concentrated on the periphery of the fan blades, the air return route is cut off by high-speed air outlet, and on the other hand, the hot air speeds of different positions of foods in the roasting pot are extremely different; the other method is that the hot air on the side face is guided to the upper part of the roasting pan through an air duct and then guided to the lower part, the air guide opening is too small and still is local hot air, the large wind power of the air guide opening is rapidly reduced, the air guide opening can not be settled to the bottom of the roasting pan at all, and the loss of wind speed and heat of an air guide path is considered, so that the method is not high in practical feasibility.

However, in practical applications, considering that food is generally placed in the middle of the pan body 2, when the pan body 2 forms other shapes and is not completely matched with the air duct outlet 6 of the cross-flow fan 3, the above-mentioned hot air flow path can be realized to fully bake the food, so the shape of the pan body 2 is not limited thereto.

As a further preferred embodiment, as shown in fig. 3 and 4, two ends of the heating pipe 7 are rotatably installed on two side walls of the air duct outlet 6 in a circumferential direction, so that the middle of the heating pipe 7 can be turned up to clean the air duct outlet 6.
