Description

Technical Field

[0001] This utility model belongs to the field of air fryer technology, specifically relating to a dual-cylinder air fryer. Background Technology

[0002] Air fryers, as kitchen appliances that utilize high-speed air circulation technology for cooking, are widely popular due to their healthy characteristics of being oil-free or low-oil cooking. However, existing air fryer technology still has significant shortcomings in terms of structural design and user experience. First, traditional air fryer pots are mostly made of opaque metal materials, making it impossible for users to directly observe the cooking process inside the pot. This makes it difficult to monitor the food's state and temperature in real time, affecting the precision and convenience of cooking. To address the visibility issue, some products have attempted to use transparent materials such as glass for the pot body, but this design often overlooks the importance of heat insulation and scalding prevention. The exposed transparent pot body reaches extremely high surface temperatures during high-temperature operation, posing a serious safety hazard to users who handle or move the food. Furthermore, existing devices generally lack optimized heat insulation performance, allowing heat from the pot body to easily conduct to external components such as the handle and base, further increasing the risk of injury. Simultaneously, it is difficult to effectively separate oil and moisture during cooking, potentially leading to greasy food or inconvenient cleaning. These problems limit the practicality and user experience of air fryers, urgently requiring an innovative solution that combines visibility, safety, and functionality. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] like Figure 1-3 As shown, this utility model provides a double-cylinder air fryer, including a body 1 and a pot assembly 2 arranged vertically. The pot assembly 2 is located directly below the body 1. The pot assembly 2 includes a transparent pot body 3 and a base 4 connected vertically. The pot body 3 is made of glass. The base 4 is located below the pot body 3 to support the bottom of the pot body 3. The pot body 3 has a hollow design and an internal cooking cavity 31 for placing food. The top of the pot body 3 has an opening 32 communicating with the cooking cavity 31. The opening 32 faces the body 1 and is detachably connected to the body 1 vertically. The bottom of the pot body 3 and the base 4 are detachably connected vertically by a latch. The base 4 has a switch button 45 for controlling the latch. The outer peripheral wall and bottom of the pot assembly 2 are also covered with a transparent heat insulation cover 5. The heat insulation cover 5 is made of transparent glass, high-temperature resistant acrylic, or any transparent material. Most air fryers on the market have an opaque metal pot body 3, making it impossible for users to observe the cooking process inside in real time. To solve the problem of visualizing the cooking process, pot bodies made of transparent materials, such as glass, have appeared on the market. However, to achieve the visualization effect of the transparent pot body 3, it must be exposed. This design brings a problem: the exposed pot body 3 gets too hot during cooking and can easily burn the user. To solve this problem, this application adds a transparent heat insulation cover 5 to the transparent pot body 3, so that the cooking process inside the cooking cavity 31 can be observed through the heat insulation cover 5 and the pot body 3, while also providing heat insulation and preventing burns to the pot body 3.

[0032] Specifically, such as Figure 3 As shown in the figure, in one embodiment of this utility model, there is a gap between the inner peripheral wall of the heat insulation cover 5 and the outer peripheral wall of the pot body 3. These gaps form an annular first heat insulation cavity 6. This structural design avoids direct contact between the pot body 3 and the heat insulation cover 5, thereby accelerating the heat conduction speed of the pot body 3 to the heat insulation cover 5. As can be seen from the figure, the base 4 is provided between the bottom of the heat insulation cover 5 and the bottom of the pot body 3, so that the heat insulation cover 5 does not directly contact the pot body 3 at the bottom, further slowing down the heat conduction speed of the pot body 3 to the heat insulation cover 5.

[0033] Specifically, such as Figure 4-5As shown, in one embodiment of this utility model, the base 4 has four downwardly extending positioning posts 41 at its bottom, and the heat insulation cover 5 has four positioning holes 51 at its bottom that correspond vertically to the positioning posts 41. When connected, the base 4 and the heat insulation cover 5 are vertically aligned, and the positioning posts 41 are fitted into the positioning holes 51, so that the base 4 and the heat insulation cover 5 are connected vertically and vertically. At the same time, it can also prevent the base 4 and the heat insulation cover 5 from having lateral relative displacement.

[0034] Furthermore, such as Figure 4-5 As shown, the base 4 has four first screw holes 42 at its bottom, and the heat insulation cover 5 has four second screw holes 52 at its bottom that correspond vertically to the first screw holes 42. The first screw holes 42 are located on one side of the positioning post 41, and the second screw holes 52 are located on one side of the positioning hole 51. When the positioning post 41 and the positioning hole 51 are engaged vertically, the first screw holes 42 and the second screw holes 52 are automatically aligned vertically. Then, by simultaneously screwing the first screw holes 42 and the second screw holes 52 with screws, the base 4 and the heat insulation cover 5 can be fixedly screwed together vertically.

[0035] Specifically, such as Figure 6-7 As shown in one embodiment of this utility model, the base 4 at the bottom of the pot body 3 is provided with two handles 43 extending from both sides of the base 4 to the side wall of the pot body 3. Each handle 43 includes a hand support portion 431 provided on the side wall of the pot body 3 and a connecting plate 432 connecting the hand support portion 431 and the base 4. The connecting plate 432 is arc-shaped along the outer contour of the outer wall of the pot body 3. Meanwhile, the side wall of the heat insulation cover 5 is provided with a side slot 53 for the handles 43 to pass through, so that when the user uses the handles 43, the heat insulation cover 5 can also be fitted over the pot body 3 and the base 4.

[0036] Furthermore, from Figure 7 As can be seen, the outline of the connecting plate 432 of the handle 43 is the same as that of the pot body 3, but there is still a gap between them. These gaps form a second heat insulation cavity 8 between the handle 43 and the side wall of the pot body 3. This structural design can prevent the handle 43 from directly contacting the pot body 3, which would accelerate the heat conduction speed of the pot body 3 to the handle 43 and cause the user to be burned when using the handle 43.

[0037] Specifically, such as Figure 8-9As shown in one embodiment of this utility model, a shelf 7 is also placed inside the cooking cavity 31 of the pot body 3 for placing ingredients during cooking. There is a gap between the shelf 7 and the bottom of the cooking cavity 31, which forms a water-oil cavity 71. At the same time, the shelf 7 is provided with several oil-draining holes 72 that connect to the water-oil cavity 71. During the cooking process, excess water vapor and oil produced by the ingredients will pass through the oil-draining holes 72 and be collected in the water-oil cavity 71, preventing excessive oil and water vapor from contacting and accumulating with the ingredients, which would prevent the ingredients from forming a crispy outer shell.

[0038] Furthermore, such as Figure 10-11 As shown, since the shelf 7 is made of metal, it is easy to scratch the inner wall of the cooking cavity 31 when the shelf 7 is placed inside the cooking cavity 31. To solve this problem, four spacers 73 are embedded in the peripheral wall of the shelf 7. The spacers 73 are made of high-temperature resistant soft plastic and are L-shaped. They serve as support parts 731 and fixing parts 732. The fixing parts 732 are parallel to the shelf 7 and fixed to the upper wall of the shelf 7. The support parts 731 are perpendicular to the shelf 7 and fixed to the side wall of the shelf 7. The support parts 731 can separate the side wall of the shelf 7 from the inner wall of the cooking cavity 31 from the side. On the other hand, the support parts 731 extend downward to form the distance between the shelf 7 and the cooking cavity 31 and support the shelf 7 so that the shelf 7 does not directly contact the cooking cavity 31 and avoids scratching.

[0039] Furthermore, such as Figure 10-11 As shown, the edge of the shelf 7 is provided with downwardly extending pins 74 and fixing holes 75. The fixing holes 75 include a first hole 751 near the pins 74 and a second hole 752 with a diameter larger than that of the first hole 751. A channel is provided between the first hole 751 and the second hole 752 to connect them. Correspondingly, a mushroom-shaped fixing block 733 is provided below the fixing part 732 of the foot 73. The fixing block 733 is composed of a cylinder and a hemisphere. The diameter of the cylinder is smaller than the diameter of the hemisphere, and the diameter of the hemisphere is larger than the diameter of the second hole 752. The support part 731 is provided with a mounting cavity 734 corresponding to the pins 74. During installation, since the spacer 73 is made of high-temperature resistant soft plastic, it can be twisted and deformed at will. First, the pin 74 is fitted into the mounting cavity 734, and then the fixing block 733 is pressed into the second hole 752, so that the shelf 7 is snapped between the fixing block 733 and the fixing part 732. Finally, the fixing block 733 is moved into the first hole 751 to achieve a stable connection between the spacer 73 and the shelf 7.

[0040] Specifically, such as Figure 12As shown, in one embodiment of this utility model, the bottom of the pot body 3 is provided with two protrusions 33, and the base 4 is provided with two grooves 44 corresponding to the protrusions 33. The pot body 3 and the base 4 are connected vertically, and the protrusions 33 are fitted into the grooves 44 to prevent the pot body 3 and the base 4 from lateral displacement.

[0041] Specifically, such as Figure 13 As shown in one embodiment of this utility model, a motor 11 is provided at the top inside the body 1. The motor 11 has a downwardly extending drive shaft 111. A fan assembly 12 is sleeved and connected to the drive shaft 111. A heating tube 13 is provided below the fan assembly 12. The heating tube 13 generates heat rapidly after being energized. The motor 11 drives the fan assembly 12 to rotate at high speed, blowing high-temperature air into the cooking cavity 31 of the pot body 3. The high-temperature hot air continuously wraps around the food, quickly removing the moisture from the surface of the food to form a crispy outer shell, while transferring heat to the inside to cook the food thoroughly.

[0042] Furthermore, the fan assembly 12 includes a first fan 121 and a second fan 122 arranged vertically. The first fan 121 rotates upward to cool the motor 11 and other components above it. The second fan 122 rotates downward to blow air onto the heating tube 13, thus blowing hot air into the cooking cavity 31 of the pot body 3.

[0043] In other embodiments, such as Figure 14 As shown, the volume of the pot body assembly 2 can be adjusted according to the actual situation to achieve the same effect.

[0044] The working principle of this utility model is explained in detail below: Users first place the ingredients on the rack inside the pot assembly, which is located within the cooking cavity. The rack has an oil drain hole at its bottom, forming a water-oil chamber below. Upon starting the device, the heating element inside the machine quickly generates high temperatures, while the motor drives the fan assembly to rotate at high speed. The fan assembly includes a first fan and a second fan positioned vertically. The first fan blows upwards to cool the motor and other upper components, while the second fan blows downwards, forcing the hot air generated by the heating element into the cooking cavity. The high-temperature hot air circulates within the cavity, continuously enveloping the food, quickly evaporating surface moisture to form a crispy outer shell, while simultaneously penetrating the food to ensure even cooking. During cooking, the oil and moisture released from the food drip through the oil drain hole into the water-oil chamber for collection, preventing repeated contact between oil and food and improving health benefits. Users can observe the food's condition in real time through the transparent heat shield and the transparent pot body without opening the pot, preventing heat loss. A first heat insulation chamber is located between the heat shield and the pot body, and a second heat insulation chamber is located between the handle and the pot body, effectively blocking heat transfer and preventing burns. The pot body and base are connected by a locking mechanism for easy disassembly and cleaning; the base and heat insulation cover are secured with positioning posts and screw holes to ensure overall structural stability. This design achieves a balance between efficient cooking, safe use, and convenient maintenance.

[0045] The innovation of this utility model lies in: Firstly, the double-layer design of the transparent pot body and transparent heat insulation cover allows for full visibility of the cooking process while effectively isolating the heat from the pot, preventing burns and significantly enhancing the safety and user confidence of the device. The heat insulation cavity formed between the heat insulation cover and the pot body greatly reduces the efficiency of heat conduction outwards, ensuring that external components maintain a suitable temperature and avoiding the risk of accidental burns. Secondly, the locking connection mechanism between the pot body and the base simplifies the disassembly and assembly process, making it convenient for users to clean and maintain, and enhancing the product's practicality and durability. Furthermore, the coordinated design of the storage rack and water / oil chamber efficiently separates and collects excess oil and moisture generated during cooking, reducing contact between food and oil, contributing to a crispy texture and improving the healthiness of cooking. The overall structure is scientifically designed and rationally balanced, maintaining efficient air circulation cooking performance while also considering multiple advantages such as safety protection, ease of operation, and visual monitoring, comprehensively improving the user experience and meeting the high standards of modern kitchen appliances for intelligence and user-friendliness.
