Technical Field

The utility model belongs to the technical field of household electrical appliances, concretely relates to can effectively improve air oven of effect of airing exhaust.

Background

In the production process of fried food, a fryer is traditionally used for making the fried food, but the fryer has a large amount of oil smoke in the using process, so that the fryer is used less and less in families; with the application of the high-speed air circulation technology to the food frying process, an air type frying pan is formed, the food is heated by utilizing the fast flowing hot air flow, compared with the traditional frying pan, the oil can be reduced by 80%, and the air type frying pan is convenient to clean, safe and economical in household use, popular with consumers and widely developed.

For example, chinese patent document 201310101037.9 discloses a smokeless air fryer, which specifically includes an air fryer fixing body and an air fryer moving body, wherein a top-moving type power switch is disposed on one side of a lower end surface of a boss portion of the front portion of the air fryer fixing body for mounting a timer, a top-moving type boss is disposed on one side of an upper end surface of a handle of the air fryer moving body, which is in locking and unlocking engagement with a basket, and the top-moving type power switch on one side of the lower end surface of the boss portion of the air fryer fixing body is in top-moving opening and closing engagement with the top-moving type power switch; a planar spiral electric heating pipe is arranged below a hot air fan blade in the air fryer fixing body, a power supply connector of the planar spiral electric heating pipe is connected with the inner wall of the air fryer fixing body through a connecting piece, and a pipe body of the planar spiral electric heating pipe is elastically connected with the inner wall of the air fryer fixing body through a tension spring; the middle part of the bottom of the oil receiving backflow pot in the moving body of the air fryer is arc-shaped, and the periphery of the pot wall and the pot bottom are arc-shaped.

For another example, chinese patent document 201120426783.1 discloses an oil-free frying pan with separated hot and cold air, which specifically includes an upper pan body and a lower pan body, the upper pan body and the lower pan body are respectively of an inner layer structure and an outer layer structure, a hollow air duct is formed between the inner layer and the outer layer, and the upper pan body and the lower pan body are provided with connecting holes. The upper pot body is provided with a motor and a fan connected with the motor at the top end, the left side of the motor is provided with an air inlet, an air diversion cover is arranged below the fan, a hollow heat insulation layer is arranged below the air diversion cover, the bottom of the lower pot body is provided with an air outlet, when the power is switched on to start working, heat in the pot is transferred to the hollow layer through heat radiation, the motor drives the fan to start working, cold air is sucked through the air inlet, the air is driven by the fan, the air diversion cover diverts the flow, the flow passes through a connector to the lower pot body, and finally the cold air exchange is completed through the air outlet.

Because the food processing process produces great heat, the heat that hot-blast air current in the food cooking chamber carried can be transmitted along the lateral wall of food processing cavity, leads to the casing temperature of whole equipment (for example air fryer) higher, simultaneously, still has heating parts such as motor in the casing, can not exist under the operational environment of high temperature, consequently, in time need discharge the outside of equipment with unnecessary heat in time, fast.
