Description

Technical Field

[0001] This utility model relates to the field of air fryer technology, and in particular to an air fryer that can quickly bake food. Background Technology

[0002] An air fryer is a cooking appliance that primarily heats and bakes food using rapidly circulating hot air. It mainly uses air instead of the hot oil found in a frying pan to cook food; at the same time, the hot air removes surface moisture, achieving a similar effect to deep-frying. It can also be understood as using high-temperature "air" as a medium to "fry" food. Air fryers on the market are mainly controlled by knobs or LCD touchscreens.

[0003] Qualified domestically produced air fryers must pass the "3C" certification. Their advantages include high efficiency, typically providing a delicious meal in 10-20 minutes, saving time and resources, and meeting the needs of modern people with fast-paced lifestyles. Because they utilize high temperatures to absorb the food's own oil and moisture during cooking, compared to regular fried foods, air fryer-cooked food contains less or no oil, reducing the consumer's intake of fats and making it relatively healthier.

[0004] Traditional air fryers typically heat food using only hot air, a process that takes 15 to 20 minutes, resulting in a relatively long heating time and low heating efficiency. Utility Model Content

[0005] The main purpose of this invention is to provide an air fryer that can quickly bake food, aiming to solve the problem that traditional air fryers usually only use hot air to heat food, which takes 15 to 20 minutes, resulting in long heating time and low heating efficiency.

[0008] The first heating component is installed on the top of the upper furnace body. The first heating component uses a blower to deliver air heated by an electric heating wire to heat the food inside the upper furnace body.

[0009] The second heating component is installed at the bottom of the lower furnace body. The second heating component uses a magnetron and a microcrystalline plate to microwave the food inside the upper furnace body.

[0010] The first heating assembly includes an air guide duct, a support frame, an mounting pipe, and an air inlet guide plate. The air guide duct is fixedly installed on the top of the upper furnace body, and the bottom of the air guide duct is connected to the interior of the upper furnace body.

[0035] Reference Figures 1-6 An embodiment of this utility model provides an air fryer capable of quickly baking food, comprising:

[0036] The lower furnace body 1 and the upper furnace body 2 are installed on the top of the lower furnace body 1, and a gripping bracket 14 is fixedly installed on the top of the upper furnace body 2.

[0037] The first heating component is installed on the top of the upper furnace body 2. The first heating component uses a blower 8 to deliver air heated by an electric heating wire 7 to heat the food inside the upper furnace body 2.

[0038] The second heating component is installed at the bottom of the lower oven body 1. The second heating component uses a magnetron 11 and a microcrystalline plate 16 to microwave the food inside the upper oven body 2.

[0039] It should be noted that by setting up the first heating element and the second heating element, the food inside the oven can be heated simultaneously from both the top and bottom, thereby greatly reducing the heating time required for the food and making the heating effect more efficient.

[0040] In some embodiments, such as Figure 1 As shown, the grip support 14 is located on one side of the top of the upper furnace body 2, and the grip support 14 is zigzag in shape.

[0041] It should be noted that by setting the grip bracket 14, it is easier to pick up the upper furnace body 2.

[0042] In some embodiments, such as Figure 2 As shown, a first dust filter 9 is fixedly installed at the air inlet on one side of the blower 8.

[0043] It should be noted that by setting the first dust filter 9, external impurities can be prevented from entering the upper furnace body 2 through the air inlet of the blower 8. The blower 8 mainly consists of six parts: motor, air filter, blower body, air chamber, base (also serving as oil tank), and oil drip nozzle. The blower 8 operates eccentrically by the offset rotor inside the cylinder, and the volume change between the blades in the rotor slots draws in, compresses, and discharges air.

[0044] In some embodiments, such as Figure 3 As shown, the first heating component includes an air guide duct 3, a support frame 5, an installation pipe 6, and an air inlet guide plate 20. The air guide duct 3 is fixedly installed on the top of the upper furnace body 2, and the bottom of the air guide duct 3 is connected to the inside of the upper furnace body 2. The air inlet guide plate 20 is fixedly installed on the bottom of the air guide duct 3 and is located inside the upper furnace body 2. The support frame 5 is fixedly installed on the top of the upper furnace body 2. The installation pipe 6 is fixedly installed inside the support frame 5. The electric heating wire 7 is fixedly installed inside the air guide duct 3. The blower 8 is fixedly installed at one end of the installation pipe 6. An air inlet hole 19 is opened on the side wall of the air guide duct 3 near the bottom, and one end of the air guide duct 3 corresponds to the air inlet hole 19.

[0045] It should be noted that by setting up the blower 8, external air can be delivered to the air guide duct 3 through the installation pipe 6. The air passing through the installation pipe 6 can be heated by the electric heating wire 7. Then, the hot air enters the air inlet 19 on the side wall of the air guide duct 3 through one end of the installation pipe 6, and is then guided by the air inlet guide plate 20 at the bottom of the air guide duct 3. The heated air can be delivered to the upper furnace body 2 through the air inlet guide plate 20 at the bottom of the air guide duct 3 to heat the food in the upper furnace body 2. The air inlet guide plate 20 is conical in shape, and the inner diameter of the top of the air inlet guide plate 20 is larger than the inner diameter of the bottom.

[0046] In some embodiments, such as Figure 3 As shown, a temperature sensor 4 is fixedly installed on the top of the air duct 3, and the detection end of the temperature sensor 4 is located inside the upper furnace body 2.

[0047] It should be noted that temperature sensor 4 is an NTC temperature sensor. The sensing end of temperature sensor 4 is located inside the upper furnace body 2 near the bottom, allowing for temperature detection within the upper furnace body 2. An NTC temperature sensor is a thermistor or probe; its principle is that the resistance value decreases rapidly as the temperature rises. It is typically composed of two or three metal oxides mixed in a fluid-like clay and sintered into a dense sintered ceramic in a high-temperature furnace. The actual size is quite flexible.

[0048] In some embodiments, such as Figure 4 , Figure 6 As shown, the second heating component includes a waveguide 10, a stirring motor 21, and a stirring disk 22. The waveguide 10 is fixedly installed at the bottom of the lower furnace body 1, and the top of the waveguide 10 is connected to the lower furnace body 1. The microcrystalline plate 16 is fixedly installed inside the lower furnace body 1. The stirring motor 21 is fixedly installed at the bottom of the lower furnace body 1. The stirring disk 22 is fixedly installed at the output end of the stirring motor 21 and is located at the bottom of the microcrystalline plate 16. The magnetron 11 is fixedly installed at the bottom of the waveguide 10. A fan 12 is fixedly installed on one side of the magnetron 11, and a second dust filter 13 is fixedly installed on one side of the fan 12. An air outlet 15 is opened on the side wall of the upper furnace body 2.

[0049] It should be noted that the magnetron 11 is an electrovacuum device used to generate microwave energy; essentially, it is a diode placed in a constant magnetic field. Electrons inside the magnetron, under the control of mutually perpendicular constant magnetic and electric fields, interact with a high-frequency electromagnetic field, converting energy obtained from the constant electric field into microwave energy, thus achieving the purpose of generating microwave energy. By setting up the magnetron 11, electrical energy is converted into microwaves with a frequency of approximately 2.45 GHz or 2450 MHz. The waveguide 10 is used to transmit ultra-high frequency electromagnetic waves. Through it, pulse signals can be transmitted to their destination with minimal loss. It is a hollow metal conduit or a tube lined with metal, with a very smooth inner wall. Therefore, the waveguide 10 can be used to conduct microwaves. These microwaves are transmitted through… Waveguide 10 transmits microwaves to the lower furnace body 1. A stirring motor 21 controls the rotation of the stirring disk 22. The stirring motor 21 drives the stirring disk 22 to rotate, agitating the microwaves within the lower furnace body 1. Simultaneously, the microwaves penetrate the microcrystalline plate 16 and permeate the upper furnace body 2. After multiple reflections from the inner wall of the upper furnace body 2, they are evenly distributed within it. The polar water molecules in the food absorb the microwave energy. Under the influence of a high-frequency alternating electromagnetic field, the water molecules oscillate rapidly billions of times per second in the direction of the electric field. This violent motion causes intermolecular friction and heat generation, thus achieving the desired effect on the food in the upper furnace body 2. The microwave heating effect is enhanced by a second dust filter 13, which prevents the fan 12 from conveying impurities into the lower oven body 1. The microcrystalline plate 16 is transparent to microwaves (allowing microwave penetration), allowing microwaves to pass through it without obstruction and directly heat the food and containers placed above it. While the microcrystalline plate 16 can hold food, microwaves can still enter the upper oven body 2 through it. Furthermore, the microcrystalline plate 16 has a low coefficient of thermal expansion, meaning it expands very little when heated and contracts very little when cooled. This ensures it is not prone to cracking under the drastic temperature changes of a microwave oven. To provide stable and safe operation, the fan 12 is located on one side of the magnetron 11. By setting the fan 12, the magnetron 11 can be used for heat dissipation protection, avoiding damage caused by overheating. The stirring plate 22 is generally disc-shaped, with a semi-circular protrusion integrally formed on the top. When the stirring plate 22 rotates, it drives the semi-circular protrusion on the top to rotate as well. The stirring plate 22 is made of aluminum. The aluminum stirring plate 22 can better reflect microwaves, allowing a standing wave field to be formed in the upper oven body 2 more quickly, making the food heat more evenly. The stirring plate motor 21 is a traditional servo motor.

[0050] In some embodiments, such as Figure 5 As shown, several limiting installation columns 17 are fixedly installed on the top of the lower furnace body 1, and several limiting installation holes 18 corresponding to the several limiting installation columns 17 are opened inside the edge of the upper furnace body 2.

[0051] It should be noted that by setting the limiting mounting post 17 and the limiting mounting hole 18, it is easier to align the upper furnace body 2 with the lower furnace body 1 during assembly, so that the microcrystalline plate 16 inside the lower furnace body 1 can be completely located inside the upper furnace body 2.

[0052] Working principle: During use, the food to be heated is placed on the microcrystalline plate 16 at the top of the lower furnace body 1. Then, the upper furnace body 2 is installed on top of the lower furnace body 1 by passing the limiting mounting post 17 at the top of the lower furnace body 1 through the limiting mounting hole 18 on the edge of the upper furnace body 2, placing the food inside the upper furnace body 2. During heating, the blower 8 delivers outside air through the mounting pipe 6 to the air duct 3. The electric heating wire 7 heats the air passing through the mounting pipe 6. The hot air then enters the air inlet 19 on the side wall of the air duct 3 through one end of the mounting pipe 6, and is guided by the air inlet guide plate 20 at the bottom of the air duct 3, allowing the heated air to be delivered to the upper furnace body 2 to heat the food inside. Simultaneously, the magnetron 11 converts electrical energy into microwaves with a frequency of approximately 2.45 GHz or 2450 MHz. The microwaves are transmitted to the lower oven body 1 through the waveguide 10, and then the stirring plate 22 is rotated by the stirring plate motor 21 to stir the microwaves in the lower oven body 1. At the same time, the microwaves penetrate the microcrystalline plate 16 and fill the upper oven body 2. After being reflected multiple times by the inner wall of the upper oven body 2, they are evenly distributed in the upper oven body 2. The polar molecules of water in the food absorb the microwave energy. Under the action of the high-frequency alternating electromagnetic field, the water molecules will oscillate rapidly with the direction of the electric field billions of times per second. This violent movement causes intermolecular friction to generate heat, thereby achieving the effect of microwave heating of the food in the upper oven body 2. At the same time, the food is heated by hot air and microwaves, making the heating of the food more efficient. The temperature sensor 4 is located in the upper oven body 2 near the bottom, so that the temperature in the upper oven body 2 can be detected. The fan 12 is set to provide heat dissipation protection for the magnetron 11 to prevent the magnetron 11 from being damaged due to overheating.

Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
