Description

Technical Field

[0001] The present application relates to the technical field of cooking equipment, and in particular to an easy-to-clean air fryer. Background Art

[0002] When frying food in an air fryer, first place the processed ingredients in the frying basket, then push the frying basket into the cooking chamber of the main body and make sure it is in place. Start the machine through the control component, the heating tube and the motor start working, the motor drives the centrifugal fan blades to rotate at high speed, forming a high-speed airflow in the frying basket cavity, and at the same time, the heat generated by the heating tube is brought into the frying basket, so that the food in the frying basket is fully exposed to the high-temperature airflow and heated until cooked.

[0003] However, the heating tube of the existing air fryer is directly designed on the upper part of the cooking cavity of the main body, and the frying basket is arranged below the heating tube. When the air fryer is working, the centrifugal fan blades rotate at high speed under the drive of the motor, driving the air in the cooking cavity to circulate at high speed. Under the action of the centrifugal fan blades, the air passes through the heating tube to flow to the frying basket, and then flows upward from the bottom of the frying basket and passes through the heating tube to reach the centrifugal fan blades, and the cycle is repeated.

[0004] However, during the baking process, as the temperature of the food rises, a large amount of water vapor will evaporate, and a large amount of grease will also be discharged. These water vapor and grease will circulate repeatedly under the action of high-speed airflow. During the flow, the grease carried by the high-speed airflow will adhere to the heating tube and the fan blades. As the product is used for a longer time, the amount of grease adhered will increase. In addition, most of the heating tubes are designed like mosquito coils, which are very difficult to clean. Especially the centrifugal fan blades, which are located above the heating tubes and are completely blocked by the heating tubes, cannot be cleaned at all. Over time, the grease becomes oily dirt, which will produce odor when working. What is more serious is that such grease may undergo various chemical reactions under the action of high temperature and become toxic substances, which seriously threaten the health and safety of consumers.
