Description

Air fryer

Technical field

The present invention relates to a food cooking appliance, and more particularly to an air fryer that is cooked by air as a medium.

Background technique

The existing air fryers include a pot lid, a pot body, a frying basket, an outer pot, a heating body and a fan. The bottom of the frying basket is an oil leakage hole, and the outer pot receives oil water, and the heating body and the fan are all installed in the lid. The hot air is sprayed from the center of the lid and then discharged from the periphery of the lid. The hot air is circulated in the frying basket. When the hot air blows down, it is quickly blocked by the food. The hot air can't turn the food over, causing the food in the upper layer of the fry basket to be Charred, the food under the bottom of the basket is not cooked, so the current air fryer must be shut down frequently, then the basket is taken out, the food is shaken and the food is re-opened.

Summary of the invention

Accordingly, it is an object of the present invention to provide an air fryer that enables hot air to penetrate all food.

The object of the invention is achieved in this way.

An air fryer includes a pot lid, a pot body, a fry basket, an outer pot, a heating element, and a fan.

The heating element and the fan are disposed at the center of the bottom of the pot body, the hot air outlet is located above the heating element, and the cold air inlet is located below the fan.

The central portion of the outer pot is bulged upwardly with a hollow gas permeable column, the gas permeable column is electrically connected to the hot air outlet, and the outer pot overhead seat is disposed in the main body of the pot, and the outer pot side wall is separated from the inner wall of the pot body.

The bottom of the bottom surface of the frying basket is provided with a positioning hole, and the gas permeable column passes through the positioning hole upwards to set the frying basket seat in the inner cavity of the outer pot. The bottom surface of the frying basket is provided with an oil leakage hole, and the outer surface of the fry basket is separated from the inner surface of the outer pot.

The inner surface of the lid is provided with a wind guide baffle. After the lid is closed with the pot body, the gas permeable column communicates with the inner chamber of the fry basket, and the air baffle is sealed with the port on the fry basket. The lids are separated.

The pot body around the bottom surface of the outer pot is provided with a hot gas passage for exhausting hot air.

The gap between the fry basket and the outer pot, the gap between the outer pot and the pot body, and the hot gas passage are connected one by one to form a passage for discharging heat to the inner cavity of the fry basket.

The cold air inlet, the hot air outlet, and the venting column form a passage for transferring heat to the interior of the fry basket.

The above technical solutions can also be further improved as follows.

A cavity is formed at the bottom of the main body of the pot, a heating element and a fan are disposed in the cavity, a cold air inlet is disposed on a bottom surface of the corresponding body of the cavity, and a hot air outlet is disposed on a top surface of the cavity.

The hot air outlet has a tapered shape and is thick and thin.

The shape of the gas permeable column is tapered, and the upper and lower sides are thick, and the bottom port of the gas permeable column is sleeved on the hot air outlet.

A hollow positioning post extends upwardly around the positioning hole of the frying basket, and the positioning post is sleeved outside the gas permeable column, and the shape of the positioning column is consistent with the gas permeable column.

The air guiding baffle corresponding to the top port of the gas permeable column has a downward convex spherical shape.

The structural design of the invention is simple and reasonable. By moving the heating element and the fan to the bottom of the main body of the pot, the hot air can only flow downward in the frying basket, tumbling the food, and then the heat flows out from the oil leakage hole on the bottom of the frying basket, and the food is heated. Uniform, short heating time, energy saving, easy to clean and hygienic body. The air inlet passage and the exhaust passage are independent of each other, and the air flows smoothly.
