Description

Technical Field

[0001] This utility model relates to the field of air fryer technology, and in particular to a high heat dissipation air fryer. Background Technology

[0002] With the growing popularity of healthy eating concepts and continuous technological advancements, air fryers, as a new type of kitchen appliance, are experiencing a broader development prospect. Air fryers primarily utilize air instead of the hot oil in a frying pan, employing convection mechanisms and a mechanical fan to circulate hot air at high speed around the food to cook it. During this process, the air fryer creates a crispy layer on the food through the Maillard reaction and caramelization browning reaction, achieving an effect similar to deep-frying.

[0003] The cooling duct is a crucial component of an air fryer. Its primary function is to dissipate the heat generated during operation. Effective heat dissipation ensures the stable operation of internal components, preventing performance degradation or damage due to overheating, thus extending the lifespan of the appliance. Currently, most air fryers on the market use a pre-drilled gap or hole at the top as the air inlet for the cooling duct. An internal fan then draws in hot air, expelling it through an exhaust vent at the back. However, this top-mounted air inlet design detracts from the air fryer's aesthetics, and this single-duct structure generally offers limited heat dissipation.

[0004] Therefore, there is an urgent need for a high-efficiency air fryer that is both aesthetically pleasing and has high heat dissipation efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a high-heat-dissipation air fryer that is aesthetically pleasing and has high heat dissipation efficiency.

[0014] Preferably, the high-heat-dissipation air fryer further includes an air duct, which is located inside the housing and the second air inlet channel is located inside the air duct. The air duct includes a first opening and a second opening, which are connected through the second air inlet channel.

[0020] This utility model proposes a high-heat-dissipation air fryer, including a shell, an electronic control board, and a control component.

[0036] An air fryer is a kitchen appliance that uses air instead of hot oil in a frying pan. It cooks food by using convection and a mechanical fan to circulate hot air at high speed around the food. Internally, it typically contains an electronic control board (ECU), which uses a microcontroller or digital signal processor as its core processing unit to execute pre-set program code and manage the entire system. The ECU not only controls the power supply but also integrates various sensors, such as temperature and current sensors. These sensors monitor the device's operating status in real time and adjust the system accordingly based on feedback. During this process, the ECU generates heat; therefore, it needs to be cooled down to ensure stable operation.

[0037] Reference Figures 1 to 9 This describes the high heat dissipation air fryer proposed in this embodiment.

[0038] This embodiment proposes a high-heat-dissipation air fryer, including a shell 1, an electronic control board 2, and a control component 3. The electronic control board 2 is disposed inside the shell 1. The shell 1 is provided with a first air inlet channel, a second air inlet channel, and an air outlet channel. Cold air can flow to the electronic control board 2 through the first air inlet channel and the second air inlet channel, and then flow out through the air outlet channel. The control component 3 includes a connecting plate 31, which is disposed on the front side wall of the shell 1. A first air inlet 311 is provided on the edge of the connecting plate 31, and the first air inlet 311 is connected to the first air inlet channel. A second air inlet 11 and an air outlet 12 are provided on the rear side wall of the shell 1. The second air inlet 11 is connected to the second air inlet channel, and the air outlet 12 is connected to the air outlet channel. First, cold air can simultaneously flow through the first air inlet 311 and the second air inlet 11, and then through the first air intake channel and the second air intake channel to the electronic control board 2, forming a dual-channel heat dissipation, increasing the air intake volume and improving the heat dissipation efficiency. At the same time, the first air inlet 311 and the second air inlet 11 are respectively set on the front side wall and the rear side wall of the shell 1, realizing multi-directional air intake and forming air convection, further optimizing the heat dissipation effect. In addition, the first air inlet 311 is set on the edge of the connecting plate 31. Utilizing the structure of the connecting plate 31, hidden air intake is achieved, achieving no visual trace of openings and improving the appearance of the air fryer.

[0039] Furthermore, the cool air from the front of the housing 1 flows to the electronic control board 2 through the first air inlet 311 and the first air intake channel, thereby cooling the electronic control board 2. Similarly, the cool air from the rear of the housing 1 flows to the electronic control board 2 through the second air inlet 11 and the second air intake channel, further cooling the electronic control board 2. This dual-channel air intake on the front and rear of the housing 1 significantly improves heat dissipation efficiency. Simultaneously, the airflow from both sides creates air convection, further optimizing heat dissipation and increasing service life. The hot air generated after the cool air carries away the heat from the electronic control board 2 is discharged through the air outlet 12 via the air outlet channel. The air outlet 12 is located on the rear wall of the housing 1, avoiding the user's operating area and preventing burns from the hot air. In addition, the control component 3 is the control panel. The control component 3 includes a connecting plate 31, which is the supporting structure in the control panel. The connecting plate 31 is located on the front side of the housing 1 for easy user operation. The first air inlet 311 is located on the edge of the connecting plate 31, which perfectly integrates the heat dissipation function and the operation interface. The edge opening design maintains the surface flatness of the connecting plate 31 and does not affect the user's operation. At the same time, it achieves concealed air intake and ensures the aesthetic appearance of the air fryer.

[0040] Specifically, the first air intake channel includes a first cooling zone. A receiving groove 13 is recessed on the front side wall of the housing 1. A connecting plate 31 is located within the receiving groove 13 and is connected to the groove wall of the receiving groove 13, forming the first cooling zone. The control component 3 also includes electronic components, which are mounted on the connecting plate 31 and located within the first cooling zone. The first cooling zone is connected to the first air inlet 311. In other words, the first cooling zone is the front half of the first air intake channel. When cold air enters the first air intake channel through the first air inlet 311, it first enters the first cooling zone of the first air intake channel. The first cooling zone is the area enclosed between the connecting plate 31 and the bottom of the receiving groove 13. The control component 3 also includes electronic components, namely the electronic components on the control panel, typically including circuit breakers and relays. When the connecting plate 31 is connected to the groove wall of the receiving groove 13, the electronic components are located within the receiving groove 13, i.e., within the first cooling zone. When the cold air from the front of the housing 1 flows through the first air inlet 311 and the first air intake channel to the electronic control board 2, the cold air first enters the first cooling zone of the first air intake channel from the first air inlet 311, thereby cooling down the electronic components. Since the electronic components themselves also generate heat, the cold air entering the first cooling zone to cool down the electronic components can improve the user's feel when operating the control component 3, and at the same time improve the service life of the electronic components.

[0041] Furthermore, the first air intake channel also includes a second cooling zone. A vent 131 is provided at the bottom of the receiving slot 13. The first and second cooling zones are connected through the vent 131, and the electronic control board 2 is located within the second cooling zone. In other words, the second cooling zone is the latter half of the first air intake channel. When cold air enters the first air intake channel through the first air inlet 311, it first enters the first cooling zone of the first air intake channel to cool the electronic components, and then enters the second cooling zone through the vent 131 to cool the electronic control board 2.

[0042] It should be noted that although electronic components themselves generate heat, their power is far lower than that of the control board 2. Therefore, when cold air enters the first air intake channel from the first air inlet 311, it first cools the electronic components in the first cooling zone without significantly increasing the air temperature. At this point, the air can enter the second cooling zone through the vent 131 to cool the control board 2, without affecting its heat dissipation effect. In other words, as long as sufficient airflow passes through the control board 2, even if the airflow temperature rises slightly, the overall heat dissipation power can still meet the requirements. This arrangement allows the cooling air entering the first air intake channel from the first air inlet 311 to flow sequentially through the electronic components and the control board 2, achieving efficient utilization of the limited cooling airflow.

[0043] In addition, the first air inlet 311 is located on the bottom edge of the connecting plate 31, and the vent 131 is located on the upper edge of the bottom of the receiving groove 13. The first air inlet 311 and the vent 131 are located at opposite ends of the diagonal of the first cooling zone. First, the first air inlet 311 is located on the bottom edge of the connecting plate 31, which further improves the concealment and also prevents foreign objects from entering the receiving groove 13 of the housing 1 through the first air inlet 311, thus improving safety. Second, the first air inlet 311 and the vent 131 are located at opposite ends of the diagonal of the first cooling zone. By utilizing the limited space of the first cooling zone, the distance between the first air inlet and the vent 131 is maximized, ensuring that the cooling can stay in the first cooling zone and thus cool down the electronic components.

[0044] The connecting plate 31 and the groove wall of the receiving groove 13 are connected by snap-fit. This detachable connection method ensures connection stability while facilitating the user to remove the control component 3 from the housing 1 by removing the connecting plate 31, thereby facilitating the inspection and maintenance of the electronic components on the connecting plate 31. In this embodiment, protrusions are provided on the four edges of the connecting plate 31, and grooves are provided on the four walls of the receiving groove 13. The protrusions can be placed in the grooves, thereby realizing the connection between the connecting plate 31 and the housing 1. Of course, in other embodiments, holes can also be provided on the four edges of the connecting plate 31, and protrusions can be provided on the four walls of the receiving groove 13, with the protrusions passing through the holes, thereby realizing the connection between the connecting plate 31 and the housing 1. This is not limited here.

[0045] Reference Figures 4 to 8 The high-heat-dissipation air fryer also includes an air duct 4, which is located inside the housing 1. A second air inlet channel is located within the air duct 4. The air duct 4 includes a first opening 41 and a second opening 42, which are connected by the second air inlet channel. The first opening 41 faces the second air inlet 11, and the second opening 42 faces the electronic control board 2. The air duct 4 is a hollow pipe. When cold air passes through the second air inlet 11 and then through the second air inlet channel, the air duct 4 provides guidance, directing the cold air to a designated location for better cooling. Specifically, before the cold air from the rear of the housing 1 enters the air duct 4 through the second air inlet 11, it enters the second air inlet channel inside the air duct 4 through the first opening 41, then flows out through the second opening 42 and towards the electronic control board 2, cooling the electronic control board 2.

[0046] To further improve heat dissipation, the end wall of the air duct 4 near the second opening 42 is fitted against the bottom wall of the electronic control board 2. This design allows cold air to be directly blown onto the surface of the electronic control board 2 through the air duct 4, reducing airflow leakage and dispersion, and ensuring maximum contact between the cold air and the electronic control board 2, thereby improving heat dissipation. It should be noted that the air duct 4 also has a third opening 43, located at the end of the air duct 4 near the second opening 42. The ventilation area of ​​the third opening 43 is smaller than that of the second opening 42. The third opening 43 ensures that the end wall of the air duct 4 near the second opening 42 is not completely sealed against the bottom wall of the electronic control board 2, allowing a small amount of cold air to flow out. This ensures air convection with the cold air entering from the first air inlet 311, while also relieving pressure and preventing the air duct 4 from shaking.

[0047] Furthermore, the air duct 4 is provided with a neck 44, and the inner diameter of the air duct 4 gradually increases from the neck 44 to the end near the second opening 42. That is to say, a section with a small cross-sectional area is set in the middle of the air duct 4 as the neck 44, forming a bottleneck of the second air intake channel. When the cold airflow passes through this point, it accelerates due to the sudden narrowing of the channel. From the neck 44 to the second opening 42, the inner diameter of the air duct 4 gradually increases, forming a funnel-shaped expansion structure, which causes the high-speed airflow to gradually decelerate and diffuse in this area, resulting in the Venturi effect, enhancing the airflow penetration, and directly blowing onto the electronic control board 2, thereby improving the cooling efficiency.

[0048] Additionally, refer to Figure 9A heat dissipation window 14 is provided on the rear side wall of the housing 1. The heat dissipation window 14 includes an air inlet area and an air outlet area. A second air inlet 11 is located in the air inlet area, and an air outlet 12 is located in the air outlet area. The second air inlet 11 and the air outlet 12 adopt an integrated design. The heat dissipation window 14 is divided into an air inlet area and an air outlet area by a guide pipe 4. The first opening 41 of the guide pipe 4 connects with the air inlet area on the heat dissipation window 14 to form the second air inlet 11. There is no need to set multiple air inlets. The heat dissipation window 14 is divided into an air inlet area and an air outlet area by the guide pipe 4, which reduces costs. A guide fin can be set on the heat dissipation window 14. When cold air enters from the second air inlet 11 in the air inlet area or flows out from the air outlet 12 in the air outlet area, it can straighten the airflow, reduce airflow separation and turbulence generation, thereby reducing the resistance of airflow when passing through the heat dissipation window 14.

[0049] The high-heat-dissipation air fryer also includes a fan 5, which is located inside the housing 1. The fan 5 is used to draw cold air into the housing 1 through the first air inlet 311 and the second air inlet 11, and to discharge the cold air through the air outlet 12, forming a directional airflow circulation to ensure stable operation of the cooling process.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
