Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an air fryer with high-efficiency heat dissipation. Background Technology

[0002] As a relatively new kitchen appliance, air fryers have gained widespread recognition and rapid development in the market in recent years due to their healthy and convenient cooking methods. Air fryers heat and cook food using rapidly circulating hot air, achieving a similar effect to deep-frying without the use of large amounts of oil, thus satisfying consumers' pursuit of healthy eating. However, with the continuous improvement of air fryer performance and the increasing diversification of usage scenarios, its heat dissipation performance has gradually become a key factor restricting its further development.

[0003] Traditional air fryers generate a significant amount of heat during operation. This heat is primarily concentrated above the cooking chamber, heating the air and creating circulating hot air for rapid food cooking. However, due to the lack of effective insulation between the hot air duct and the air fryer's outer shell, heat is continuously conducted upwards, causing the top of the air fryer to overheat. Even with heat dissipation channels at the top, it's difficult to effectively dissipate the heat diffusing upwards. This not only reduces the air fryer's lifespan but also poses safety hazards such as burns to users. Furthermore, excessively high temperatures can affect the normal operation of internal electronic components, leading to equipment malfunction.

[0004] To address this issue, some existing technologies attempt to install heat insulation panels at the top of the hot air duct to reduce upward heat diffusion. However, this simple insulation measure is often ineffective and cannot fundamentally solve the heat dissipation problem. Moreover, the heat insulation panels themselves do not effectively lower the temperature at the top of the air fryer; heat still accumulates above the insulation panels, leading to excessively high top temperatures.

[0005] Meanwhile, while the transparent window design of air fryers makes it convenient for users to observe the cooking process, the decorative ring around the window is also susceptible to heat damage in high-temperature environments. If the temperature of the decorative ring cannot be effectively reduced, it may deform, age, or become damaged, affecting the overall appearance and lifespan of the air fryer.

[0006] In conclusion, existing air fryers have significant shortcomings in heat dissipation and insulation, failing to meet users' needs for efficient heat dissipation and safe use. Therefore, developing an air fryer with efficient heat dissipation is of great significance for improving air fryer performance and user experience. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of poor heat dissipation in existing air fryers and to provide an air fryer with high-efficiency heat dissipation, which effectively slows down the temperature rise rate at the top of the air fryer, improves the service life and safety of the equipment, and protects components such as the decorative ring.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An air fryer with high-efficiency heat dissipation includes:

[0010] The fryer body internally defines a cooking cavity and a hot air channel for inputting heated air into the cooking cavity, the upper side of which is configured with a heat insulation plate; and

[0011] A decorative ring, the central part of which defines a viewing window for viewing the cooking cavity, the upper opening of which is provided with a transparent panel, and the decorative ring is positioned above the cooking cavity;

[0012] The hot air channel has an air duct partition above it, the upper part of which defines a first air duct for cooling the decorative ring, and the lower part of which defines a second air duct for blocking the upward transmission of heat from the hot air channel. The second air duct is formed between the air duct partition and the heat insulation plate.

[0013] The air duct partition has a connecting hole for connecting the first air duct and the second air duct.

[0014] Furthermore, an inner transparent plate is installed at the lower part of the decorative ring, and the edge of the inner transparent plate is installed close to the side wall of the second air duct.

[0015] Furthermore, the side of the fryer body defines a circulation chamber with a centrifugal fan. The circulation chamber is provided with a circulation air outlet communicating with the hot air channel and a circulation air inlet communicating with the cooking cavity. The centrifugal fan is configured to generate circulating air through the cooking cavity. The circulating air enters the hot air channel through the circulation air outlet and then enters the cooking cavity, and then returns to the circulation chamber through the circulation air inlet.

[0016] Furthermore, a first air guide and diverter is provided at the air inlet of the hot air channel. The first air guide and diverter is configured to guide the airflow entering from the air inlet into the hot air channel from two directions.

[0017] Furthermore, the first air duct has an air inlet for inputting cooling airflow, and the connecting hole is configured to be located away from the air inlet to extend the travel path of the cold air in the first air duct after it enters the first air duct through the air inlet.

[0018] Furthermore, a cold air cavity is defined on the side of the fryer body, and the air inlet is connected to the cold air cavity.

[0019] Furthermore, the sidewall of the hot air channel also defines a third air duct, which is located below the heat insulation plate and is configured to block the heat of the hot air channel from diffusing outward through the sidewall.

[0020] Furthermore, the heat insulation plate is provided with air guide holes, which are configured to connect the second air duct and the third air duct, and introduce the air in the second air duct into the third air duct.

[0021] Furthermore, the air fryer has a first exhaust vent on its bottom side wall. The first exhaust vent is configured to guide the air in the first air duct downwards through the side of the air fryer and dissipate heat from the side before exhausting it.

[0022] Furthermore, the air fryer has a second exhaust vent on its top side wall, and the second air duct has an air outlet channel. The second exhaust vent is configured to communicate with the air outlet channel and exhaust the air in the second air duct.

[0023] By adopting the above technical solution, this utility model has at least the following beneficial effects:

[0024] 1. This utility model of an air fryer utilizes a baffle design to divide the space above the hot air channel into a first air channel and a second air channel. The first air channel cools the decorative ring, while the second air channel helps to prevent heat from rising directly from the hot air channel. The presence of the second air channel obstructs the upward movement of heat, preventing it from reaching the top of the air fryer directly, thus providing insulation. This design significantly improves the insulation effect at the top of the hot air channel, preventing disorderly heat accumulation at the top of the air fryer. It effectively alleviates problems such as shell deformation and electronic component failure caused by excessively high top temperatures in traditional air fryers, significantly extending the overall lifespan of the air fryer and saving users the cost and effort of frequent equipment replacements.

[0025] 2. This utility model employs a unique air duct design, further improving heat dissipation efficiency. The first air duct has an air inlet, and the second air duct has a connecting hole, which is located away from the air inlet. This design extends the travel path of the cold air within the first air duct, allowing the cold air to absorb heat more fully, thereby improving heat dissipation efficiency.

[0045] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0046] This embodiment provides an air fryer with high-efficiency heat dissipation, including:

[0047] The fryer body internally defines a cooking cavity and a hot air channel for introducing heated air into the cooking cavity; the upper side of the hot air channel is equipped with a heat insulation plate; and

[0048] A decorative ring, the middle of which defines a viewing window for viewing the cooking cavity, with a transparent panel at the upper opening of the viewing window, and the decorative ring positioned above the cooking cavity;

[0049] The hot air passage has an air duct baffle above it, which defines a first air duct for cooling the decorative ring above the air duct baffle and a second air duct for blocking the upward transmission of heat from the hot air passage below the air duct baffle. The second air duct is formed between the air duct baffle and the heat insulation plate.

[0050] The air duct partition has connecting holes for connecting the first air duct and the second air duct.

[0051] See Figures 1 to 3 The air fryer includes a fryer body 100 and a decorative ring 110. The fryer body 100 has an internal cooking cavity 101, which is the space for placing food for cooking. The shape and size of the cooking cavity 101 can be designed according to actual needs to accommodate cooking different sizes and quantities of food. Inside the fryer body 100, a hot air channel 121 is also provided for inputting heated air into the cooking cavity 101. An insulation plate 122 is configured on the upper side of the hot air channel 121. The insulation plate 122 is made of a high-temperature resistant and heat-insulating material, such as ceramic fiber board or aerogel insulation material. Its main function is to reduce the upward transfer of heat within the hot air channel 121, thereby lowering the temperature at the top of the air fryer.

[0052] The decorative ring 110 defines a viewing window in the middle for viewing the cooking cavity 101. A transparent panel 112 is provided at the upper opening of the viewing window. The transparent panel 112 is made of a high-temperature resistant, high-strength transparent material, such as tempered glass or polycarbonate, allowing users to easily observe the cooking process of the food. The decorative ring 110 is installed above the cooking cavity 101, serving not only a decorative function but also providing a supporting structure for the transparent panel 112.

[0053] In terms of heat dissipation structure, a duct baffle 134 is provided above the hot air channel 121, dividing the space above the hot air channel 121 into a first duct 131 and a second duct 132. The duct baffle 134 is made of metal, such as aluminum or stainless steel, and has good thermal conductivity and structural strength. The first duct 131 is located above the duct baffle 134 and is mainly used to cool the decorative ring 110. The second duct 132 is located below the duct baffle 134, formed between the duct baffle 134 and the heat insulation plate 122, and its function is to block the upward transmission of heat from the hot air channel 121. The duct baffle 134 has connecting holes 1321 for connecting the first duct 131 and the second duct 132. The number and size of the connecting holes 1321 are designed according to the actual heat dissipation requirements and are usually evenly distributed on the duct baffle 134.

[0054] In some embodiments, an inner transparent panel is installed at the lower part of the decorative ring, and the edge of the inner transparent panel is installed close to the side wall of the second air duct.

[0055] See Figure 3 In this embodiment, an inner viewing plate 111 is installed at the lower part of the decorative ring 110, and the edge of the inner viewing plate 111 is installed close to the side wall of the second air duct 132. A sealing ring can be provided at the edge of the inner viewing plate 111 to ensure that it fits tightly with the side wall of the second air duct 132. This not only enhances the heat insulation effect of the second air duct 132, but also provides a stable installation structure for the decorative ring 110, preventing the decorative ring 110 from deforming due to heat and affecting its fit with the second air duct 132.

[0056] In this embodiment, the inner transparent panel 112 is made of a material with high transparency and high heat resistance, such as polycarbonate (PC) and polymethyl methacrylate (PMMA, also known as acrylic).

[0057] In some embodiments, the side of the fryer body defines a circulation chamber with a centrifugal fan. The circulation chamber has a circulation outlet communicating with a hot air passage and a circulation inlet communicating with a cooking cavity. The centrifugal fan is configured to generate circulating air through the cooking cavity. The circulating air enters the hot air passage through the circulation outlet and then enters the cooking cavity, and then returns to the circulation chamber through the circulation inlet.

[0058] See Figure 3The fryer body 100 defines a circulation chamber 123 with a centrifugal fan 124 on its side. The circulation chamber 123 has a circulation outlet communicating with a hot air passage 121 and a circulation inlet communicating with a cooking cavity 101. The centrifugal fan 124 is installed in the circulation chamber 123 and is driven to rotate by a motor. In actual operation, the centrifugal fan 124 rotates, drawing air from the cooking cavity 101 into the circulation chamber 123 through the circulation inlet, and then sending it into the hot air passage 121 through the circulation outlet. The hot air enters the cooking cavity 101 after passing through the hot air passage 121 to heat and cook the food. Afterward, the air returns to the circulation chamber 123 through the circulation inlet, forming a circulating airflow through the cooking cavity 101. To improve the heating effect, a heating element 125 can be installed in the hot air passage 121. The heating element 125 uses resistance wire heating, which generates heat to heat the air when energized.

[0059] In some embodiments, a first air guide and diverter is provided at the air inlet of the hot air duct, and the first air guide and diverter is configured to guide the airflow entering from the air inlet into the hot air duct from two directions.

[0060] See Figure 8 In this embodiment, a first air guide and diverter 1212 is provided at the air inlet 1211 of the hot air channel 121. The first air guide and diverter 1212 has a Y-shaped structure and is made of plastic or metal. Its function is to guide the airflow entering from the air inlet 1211 into the hot air channel 121 from two directions, so that the airflow distribution entering the hot air channel 121 is more uniform, improving the uniformity and stability of the heated air in the hot air channel 121, thereby improving the uniformity of cooking.

[0061] In some embodiments, the first air duct has an air inlet for inputting cooling airflow, and the connecting hole is configured to be located away from the air inlet to extend the travel path of the cold air within the first air duct after it enters the first air duct through the air inlet.

[0062] In this embodiment, the first air duct 131 has an air inlet 1311 for inputting heat dissipation airflow, and the connecting hole 1321 is configured to be located away from the air inlet 1311. This layout extends the travel path of the cold air after it enters the first air duct 131 through the air inlet 131, so that the cold air can absorb heat more fully, thereby improving the heat dissipation efficiency.

[0063] In some embodiments, a cold air chamber is further defined on the side of the fryer body, and the air inlet is connected to the cold air chamber.

[0064] In this embodiment, a cold air cavity 133 is defined on the side of the fryer body 100, and an air inlet 1311 is connected to the cold air cavity 133. The cold air cavity 133 is connected to the outside air, providing a stable source of cold air for the first air duct 131. The cold air enters the first air duct 131 from the cold air cavity 133 through the air inlet 1311. After absorbing the heat from the decorative ring 110 and surrounding components in the first air duct 131, it enters the second air duct 132 through the connecting hole 1321, further absorbing the heat transferred upward by the hot air channel 121, and finally being discharged through the air outlet channel 1322 of the second air duct 132.

[0065] Furthermore, a second air guide and diverter is provided at the air inlet. The diverter is configured to guide the cold air entering from the air inlet into the first air duct from two directions, and / or approach the connecting hole from two directions.

[0066] See Figure 3 A second air diverter (not shown in detail in the figure) is provided at the air inlet 1311. The structure of the diverter is similar to that of the first air diverter 1212. It can guide the cold air entering from the air inlet 1311 into the first air duct 131 from two directions, and / or approach the connecting hole 1321 from two directions, thereby optimizing the flow path of the cold air in the first air duct 131 and improving the heat dissipation efficiency.

[0067] In some embodiments, the sidewall of the hot air passage further defines a third air duct located below the heat insulation plate and configured to block the heat of the hot air passage from diffusing outward through the sidewall.

[0068] In this embodiment, the sidewall of the hot air channel 121 further defines a third air duct 135, which is located below the heat insulation plate 122 and serves to block the heat of the hot air channel 121 from diffusing outward through the sidewall.

[0069] In some embodiments, the heat insulation plate is provided with air guide holes, which are configured to connect the second air duct and the third air duct, and introduce the air in the second air duct into the third air duct.

[0070] See Figure 3 and Figure 6 In this embodiment, the heat insulation plate 122 is provided with air guide holes 1221, which connect the second air duct 132 and the third air duct 135. At the high pressure end, the air guide holes 1221 introduce the air in the second air duct 132 into the third air duct 135, and at the low pressure end, the air guide holes 1221 introduce the air in the third air duct 135 into the second air duct 132, thereby realizing the airflow linkage between the air ducts and further enhancing the heat dissipation effect.

[0071] In some embodiments, a first air vent is provided on the bottom side wall of the air fryer. The first air vent is configured to guide the air in the first air duct downward through the side of the air fryer and exhaust it after dissipating heat from the side.

[0072] See Figure 3 The air fryer 100 has a first air vent 102 on the bottom side wall. The first air vent 102 guides the air in the first air duct 131 downward through the side of the air fryer 100 and exhausts it after dissipating heat from the side, thereby accelerating heat dissipation and reducing the overall temperature of the air fryer 100.

[0073] In some embodiments, a second air vent is provided on the top side wall of the air fryer, and a second air duct is provided with an air outlet channel. The second air vent is configured to communicate with the air outlet channel and discharge the air in the second air duct.

[0074] See Figure 4 and Figure 5 The second air duct 132 is provided with an air outlet channel 1322, and the top side wall of the air fryer 100 is provided with a second air outlet 103. The second air outlet 103 is connected to the air outlet channel 1322 to exhaust the air in the second air duct 132 and ensure smooth airflow in the heat dissipation air duct.

[0075] In some embodiments, an air duct plate is provided below the heat insulation plate. The air duct plate is configured to be recessed downward to form an annular air guide cavity with an upward opening, so as to form the hot air channel with the heat insulation plate, and the air duct plate has air outlet holes facing the cooking cavity.

[0076] See Figure 3 , Figure 7 and Figure 8 The specific structure of the hot air passage 121 is formed by the air duct plate 126 located at the bottom of the heat insulation plate 122 and the heat insulation plate 122 together. The air duct plate 126 is recessed downward to form an annular air guide cavity with an upward opening, and the space between it and the heat insulation plate 122 constitutes the hot air passage 121, as shown below. Figure 7 and Figure 8 As shown. The air duct plate 126 has air outlet holes 1261 evenly distributed on it, facing the cooking cavity 101. The size and distribution of these air outlet holes 1261 are precisely designed to ensure that the hot air blown out from the hot air duct 121 can enter the cooking cavity 101 evenly and heat the food from all directions.

[0077] In some embodiments, the air duct baffle is configured to be recessed upward to form a heat dissipation cavity with an opening downward, forming a first air duct with the heat insulation plate.

[0078] See Figure 3 and Figure 9 The first air duct 131 is formed by the air duct partition 134 and the heat insulation plate 122. The air duct partition 134 is recessed upward to form a heat dissipation cavity with an opening facing downward. The space between the partition 134 and the heat insulation plate 122 is the first air duct 131.

[0079] In actual use, the user places food in the detachable frying basket, then places the basket into the cooking chamber 101, sets the cooking mode and time, and starts the air fryer 100. At this time, the heating system starts working, the heating element 125 heats up, and the centrifugal fan 124 runs, forming circulating hot air to cook the food. Simultaneously, the heat dissipation system starts, and the cold air chamber 133 draws in outside cold air by creating negative pressure. The cold air enters the first air duct 131 through the air inlet 1311. After cooling the decorative ring 110 in the first air duct 131, part of the cold air enters the second air duct 132 through the connecting hole 1321, forming a heat insulation barrier above the heat insulation plate 122. The remaining cold air continues to flow in the first air duct 131 and is finally discharged from the first exhaust port 102. The cold air entering the second air duct 132 is partially diverted through the air guide 1221 into the third air duct 135 to insulate and dissipate heat from the side wall of the hot air duct 121. After cooling, the air returns to the second air duct 132. Through this workflow, the air fryer 100 maintains good heat dissipation performance during cooking, effectively reducing the top and overall temperature, ensuring stable operation of the equipment, extending its service life, and providing a safe operating environment for users.

[0080] During the manufacturing process, the machining precision and assembly technology of each component have a significant impact on the performance of the air fryer. For example, the machining dimensional precision of the air outlet 1261 of the hot air channel 121 needs to be strictly controlled to ensure that the hot air is blown out evenly; the connection between the first air channel 131 and the second air channel 132 must be well sealed to prevent cold air leakage and affect the heat dissipation effect. At the same time, in order to improve production efficiency and product quality stability, automated production lines can be used for component machining and assembly.

[0081] Furthermore, the air fryer 100 of this invention can be functionally expanded according to user needs in practical applications. For example, a temperature sensor can be installed inside the air fryer 100 to monitor the temperature of the cooking cavity 101, hot air channel 121, and outer shell of the air fryer 100 in real time, and the temperature data can be fed back to the control system. The control system can then automatically adjust the power of the heating element 125 and the speed of the centrifugal fan 124 according to the preset temperature range, achieving more precise temperature control and energy-saving effects. Smart interconnection functions can also be added. By connecting to a mobile app via wireless network, users can remotely control the air fryer 100 to start, stop, and select cooking modes, and view the cooking progress and device status in real time.

[0082] Through the above specific implementation methods, the high-efficiency heat dissipation air fryer of this utility model achieves effective heat dissipation of the top and decorative ring of the air fryer, improves the service life and safety of the air fryer, and ensures good cooking results, thus meeting users' needs for efficient heat dissipation and safe use.

[0083] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
