Embodiment 1

[0033] An air fryer, comprising an upper shell and a lower shell, the lower shell is provided with a cavity, the fryer can be detachably set in the cavity, the fryer cooperates with the cavity to form a cooking cavity, the upper The housing is provided with a hot air device, a control unit, an air duct, and a thermal fuse. The control unit and the hot air device are arranged above the cooking cavity. The hot air device includes a heating element, a fan and a motor. The heating element includes a plane spiral The electric heating tube, the fan is arranged above the plane spiral electric heating tube, the fan includes upper blades and lower blades, a cover plate is arranged between the upper blades and the lower blades, and the cover plate and the upper casing form an accommodating cavity, the control unit is arranged in the accommodating cavity, the control unit includes a main control board, the lower blade includes a horizontal portion and a drooping portion extending toward t...

Embodiment 2

[0048] The difference between the second embodiment and the first embodiment lies in that the setting of the air outlet and the rotational speed of the motor are different.

[0049] The size of the air outlet is adjustable. In this embodiment, the air outlet is provided with movable blades, which are similar to the form of shutters. When in the cooking stage, the blades are vertically arranged, so that the air outlet is small, effectively ensuring the heat during cooking. The cavity circulates to heat the food; when in the transition stage, the blades are set horizontally, so that the air outlet is larger, and more air can flow out through the air outlet, which accelerates the cooling process and reduces the impact of hot air.

[0050] In this embodiment, in the transition stage, the main control board controls the motor to work at maximum power through the thyristor, thereby driving the fan to move at high speed, accelerating the air flow, and realizing rapid cooling.

[0051...

Embodiment 3

[0054] The difference between the third embodiment and the first embodiment is that the time for the fan to continue working is judged by the temperature sensor.

[0055] In this embodiment, the fan has a built-in motor, and the main control board can directly control the speed of the fan through electrical signals, and there is no need to set up a separate motor to drive the fan, and the structure is simpler. And in this embodiment, a temperature sensor is provided in the upper casing, and the temperature sensor is arranged close to and above the hot air device. Since the temperature sensor is relatively close to the hot air device, the influence of the rising thermal air flow can be accurately tested.

[0056] In the transition stage, the heating element stops working, and the fan continues to work to drive the air circulation in the cooking cavity and the upper casing; in the end stage, a preset temperature T is set in the main control board, T=60°C, and the comparison temp...

Abstract

The invention relates to the technical field of kitchen appliance, in particular to a control method of an air fryer. The air fryer comprises an upper shell, a lower shell, a cooking cavity formed in the lower shell, a hot air device, a main control panel and an air flue, the hot air device, the main control panel and the air flue are arranged in the upper shell, wherein the main control panel and the hot air device are arranged on the cooking cavity, the hot air device comprises a heating element and a fan, and after the heating element stops working, the fan continues to work and drives airflow in the cooking cavity and the upper shell to move circularly. Wind generated by the fan drives waste heat of the heating element to move downwards, waste heat of the heating element is effectively prevented from moving upwards, the waste heat is prevented from causing heat impact on the main control panel in the upper shell, and the life of the main control panel is effectively prolonged.

Description

technical field [0001] The invention mainly relates to the technical field of kitchen appliances, in particular to a control method for an air fryer. Background technique [0002] At present, the air fryer on the market mainly adopts a fan on the top, and the fan blows to the heat-generating components arranged on the top of the machine, forcing the air to generate convection, transferring heat to the food at the bottom to heat the food. After the food is cooked, the heating element and the fan stop working, and the user is prompted that the cooking is completed. Due to the heat storage effect of the heating element, the temperature is still high within a short period of time when the heating element stops heating. Since the fan stops rotating and the density of the hot air is low, the heat generated by the heating element will naturally flow upward. A temperature shock will be caused to the fuse, circuit board, plastic casing, etc. arranged above the heating element. When ...
