Description

Technical Field

[0001] This utility model relates to the field of cooking appliances technology, specifically to an air fryer. Background Technology

[0002] An air fryer is a cooking appliance that primarily uses rapidly circulating hot air to heat and bake food. It utilizes hot air instead of hot oil to cook food quickly; simultaneously, the hot air removes surface moisture, achieving a similar effect to deep-frying. It can be understood as using high-temperature air to "fry" food. Air fryers are highly efficient, typically providing delicious meals in about 15 minutes, saving time and resources and meeting the needs of modern people with fast-paced lifestyles. Because air fryers use high temperatures to absorb the food's own oil and moisture during cooking, compared to regular deep-fried foods, air-fried food contains less or no oil, reducing the intake of fats and making it relatively healthier.

[0003] However, existing air fryers generally use centrifugal fan blades and fixed air circulation channels, resulting in poor uniformity of food baking and seriously affecting the cooking effect. Utility Model Content

[0004] In view of this, the present invention provides an air fryer to solve the problem that existing air fryers generally use centrifugal fan blades and fixed air duct circulation, which results in poor uniformity of food baking and seriously affects the cooking effect of the food.

[0005] This utility model provides an air fryer, comprising:

[0006] Deep-fried bucket;

[0007] A baking tray is provided at the bottom of the frying bucket, and the baking tray is suitable for placing the food to be cooked.

[0008] The hot air supply structure blows hot air onto the food to be cooked through air ducts.

[0009] An air guide assembly, disposed within the air duct, is adapted to change the direction of hot air blowing to deliver hot air to different areas of the food being cooked. Beneficial effects: This application employs the above technical solution, using an air guide assembly to change the direction of hot air blowing in a timely manner, improving the uniformity of baking the food, ensuring a balance in the baking temperature between the center and edges of the food, and guaranteeing the cooking effect.

[0010] Optionally, the air guide assembly includes:

[0011] The base plate forms the bottom surface of the air duct;

[0012] At least one air guide plate is spaced apart along the air duct direction, one end of the air guide plate is rotatably connected to the edge of a slot provided on the base plate; a slider is provided protruding to the side at the other end of the air guide plate.

[0013] A plate has its bottom surface slidably connected to the top surface of the base plate, and a vertical groove is provided on the plate to slidably connect with the slider; a rack structure is provided on the top surface of the plate.

[0014] The gear meshes with the rack structure;

[0015] A power component is connected to the gear, and the power component is adapted to drive the gear to rotate.

[0016] The air guide assembly is adapted to drive the plate to slide on the base plate when the gear rotates, thereby driving the slider to slide within the groove, and finally driving the air guide plate to rotate, thus changing the direction of hot air blowing. Beneficial effects: This application adopts the above technical solution, specifically defining the structure of the air guide assembly. The power component sequentially drives the gear and plate, and the angle of the air guide plate is adjusted in a timely manner in conjunction with the groove and slider structure to change the direction of hot air blowing. For areas where food is not fully baked, the angle of the air guide plate can be adjusted to concentrate the hot airflow and heat the food in that area, improving baking uniformity.

[0017] Optionally, the power component is an electric motor.

[0018] Optionally, the hot air supply structure includes:

[0019] A cross-flow fan is suitable for supplying flowing air into the air duct. All the hot air flowing through the cooking food is returned to the cross-flow fan through the return air vent, or part of the hot air flowing through the cooking food is returned to the cross-flow fan through the return air vent, and the other part of the hot air is discharged to the outside of the air fryer.

[0020] A heating element is disposed within the air duct. The heating element is suitable for heating flowing air to form hot air. Beneficial effects: This application adopts the above technical solution, where a cross-flow fan generates airflow at high speed. After the airflow passes through the heating element, its temperature rises, forming high-temperature flowing air to evenly heat the food.

[0021] Optionally, there are multiple frying barrels, each located in a different cooking chamber. All frying barrels have the same internal structure, share hot air, and each frying barrel changes the direction of hot air blowing in a timely manner through an air guide assembly.

[0022] Optionally, a reflector is provided on the top surface of the air duct; a heat insulation plate is provided on the top of the air fryer; and heat insulation blocks are provided on the outer perimeter of the air fryer. Beneficial effects: This application adopts the above technical solution to ensure that heat is located inside the air fryer, preventing heat loss and saving energy.

[0023] Optionally, multiple temperature zones are set on the baking tray, and a temperature sensor is set in each temperature zone. When the temperature sensor detects that the temperature difference between different temperature zones exceeds a set value, the air guide assembly changes the direction of hot air blowing to balance the temperature between different temperature zones. Beneficial effects: This application, by adopting the above technical solution, further improves the uniformity of baking the food by real-time monitoring of the temperature of different temperature zones and timely changing the direction of hot air blowing, thus achieving a balance in the baking temperature between the center and edges of the food and ensuring the cooking effect of the food.

[0024] Optionally, the temperature sensor is a thermistor probe sensor.

[0025] Optionally, the set value is 10 degrees Celsius.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] like Figures 1 to 5 One specific embodiment of the air fryer shown includes: a frying drum 1, a baking tray 2, a hot air supply structure, and an air guide assembly.

[0037] like Figure 1 As shown, the baking tray 2 is disposed at the bottom of the frying tub 1, and the baking tray 2 is suitable for placing the food to be cooked. The hot air supply structure blows hot air to the food to be cooked through the air duct. The air guide assembly is disposed in the air duct, and the air guide assembly is adapted to change the blowing direction of the hot air so as to blow hot air to different areas of the food to be cooked.

[0038] Specifically, such as Figures 1 to 3As shown, the air guiding assembly includes: a base plate 3, at least one air guiding plate 4 spaced apart along the air duct direction, a plate 5, a gear 6, and a power component 7; more specifically, the power component 7 can be located on the inner top surface of the air fryer, and the power component 7 is a motor; the plate 5 is arranged vertically. The base plate 3 forms the bottom surface of the air duct. One end of the air guiding plate 4 is rotatably connected to the edge of a slot provided on the base plate 3; alternatively, one end of the air guiding plate 4 can be rotatably connected to the base plate 3 via a hinge. A slider protrudes laterally from the other end of the air guiding plate 4. The bottom surface of the plate 5 is slidably connected to the top surface of the base plate 3, and a groove 17 is provided on the plate 5 along the vertical direction to slidably connect with the slider; a rack structure is provided on the top surface of the plate 5. The gear 6 meshes with the rack structure. The power component 7 is connected to the gear 6, and the power component 7 is adapted to drive the gear 6 to rotate. The air guide assembly is adapted to drive the plate 5 to slide on the base plate 3 when the gear 6 rotates, thereby driving the slider to slide within the groove 17, and ultimately driving the air guide plate 4 to rotate, thus changing the direction of hot air blowing. Hot air in the duct is blown into the frying drum 1 through the slots on the base plate 3. That is, the rotation of the gear 6 drives the plate 5 to move horizontally, and the combination of the groove 17 and the slider converts the horizontal displacement into an angular displacement of the air guide plate 4. Figure 3 The arrow at the top center indicates the rotation direction of the power component 7, the arrow on the right indicates the movement direction of the plate 5, the arrow near the slide 17 indicates the movement direction of the slide 17, and the arrow near the air guide plate 4 indicates the movement direction of the air guide plate 4.

[0039] Specifically, such as Figure 1 and Figure 4 As shown, the hot air supply structure includes a cross-flow fan 8 and a heating element. The cross-flow fan 8 is adapted to supply flowing air into the air duct. All the hot air flowing through the cooking food returns to the cross-flow fan 8 through the return air inlet 9 and the return air duct 16, or a portion of the hot air flowing through the cooking food returns to the cross-flow fan 8 through the return air inlet 9 and the return air duct 16, while the remaining portion of the hot air is discharged to the outside of the air fryer. The heating element is disposed within the air duct and is adapted to heat the flowing air to form hot air. Figure 4 The arrows indicate the flow direction of the internal circulating hot air. The cross-flow fan 8 includes a volute 14 and an impeller 15 located inside the volute 14. The cross-flow fan 8 supplies flowing air into the air duct through the provided air outlet 13.

[0040] Furthermore, there are multiple frying buckets 1, each located in a different cooking cavity. All frying buckets 1 have the same internal structure, share hot air, and each frying bucket 1 changes the direction of hot air blowing in a timely manner through an air guide assembly.

[0041] Furthermore, a reflector plate 10 is provided on the top surface of the air duct; a heat insulation plate 11 is provided on the top of the air fryer; heat insulation blocks are provided on the outer perimeter of the air fryer; and a support plate 12 is provided at the bottom of the air fryer.

[0042] Specifically, multiple temperature zones are set on the baking tray, and a temperature sensor is installed in each zone. The temperature sensor can be located at the bottom of the frying drum 1. When the temperature sensor detects that the temperature difference between different temperature zones exceeds a set value, the air guide assembly changes the direction of the hot air to balance the temperature between the different zones. The temperature sensor is a thermistor probe sensor; the set value is 10 degrees Celsius, or more specifically, 2 degrees Celsius. Figure 5 As shown, there are three temperature zones: a third temperature zone 20, a second temperature zone 19, and a first temperature zone 18, which are arranged along the direction of hot air flow in the air duct. When the temperature of the first temperature zone 18 is higher than the temperature of the second temperature zone 19 by a set value, the air guide assembly blows hot air towards the second temperature zone 19.

[0043] When the temperature in the first temperature zone 18 is more than 10 degrees Celsius higher than the temperature in the third temperature zone 20, it indicates that there is less heat convection in the third temperature zone 20. The angle of the air guide plate 4 is adjusted by the motor, and the angle of the air guide plate 4 is not less than 120 degrees. Furthermore, the greater the temperature difference between the first temperature zone 18 and the third temperature zone 20, the larger the angle of the air guide plate 4.

[0044] When the temperature in the first temperature zone 18 is more than 10 degrees Celsius lower than the temperature in the third temperature zone 20, it indicates that there is less heat convection in the first temperature zone 18. The angle of the air guide plate 4 is adjusted by the motor, and the angle of the air guide plate 4 is no greater than 60 degrees. Furthermore, the greater the temperature difference between the first temperature zone 18 and the third temperature zone 20, the smaller the angle of the air guide plate 4. When the angle of the air guide plate 4 is 0 degrees, the air guide plate 4 closes the slot on the base plate 3.

[0045] When the temperature difference between the first temperature zone 18 and the third temperature zone 20 is within 10 degrees Celsius, it indicates that the heat distribution inside the fryer 1 is relatively uniform.

[0046] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
