Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a dual-air duct air fryer. Background Technology

[0002] Air fryers are easy to use. They replace traditional oil soaking with hot air circulation, allowing you to make crispy fried food without oil, and their popularity continues to increase.

[0003] Hot air flows inside the air fryer, heating the food while transferring heat to the fryer itself. However, the electronic components inside the air fryer have limited temperature resistance, necessitating a cooling system to protect them. This cooling system requires additional components such as cooling fans and cold air ducts, increasing the manufacturing and maintenance costs of the air fryer. The extra cooling structure also contributes to noise levels and reduces the air fryer's capacity, negatively impacting the user experience.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a dual-air duct air fryer to simplify the heat dissipation structure of the air fryer.

[0006] The technical solution of this utility model is as follows: The dual-duct air fryer includes an outer shell, a frying drum disposed within a cavity of the outer shell, and an air duct assembly. A first cold air vent is formed at the top of the outer shell, and a second cold air vent and a hot air outlet are formed adjacent to each other on the side of the outer shell. An independent air inlet and outlet duct are provided within the air duct assembly. One end of the air inlet duct connects to the cavity, and the other end connects to the frying drum. A fan and a heating element are disposed within the air inlet duct. The air outlet duct connects to the frying drum and simultaneously covers and connects to the hot air outlet.

[0007] A further technical solution is that the air duct assembly includes an upper air duct cover and a lower air duct cover. The upper air duct cover and the lower air duct cover are coupled to form the air inlet duct and the air outlet duct.

[0008] A further technical solution is that a hook is provided on one side of the lower cover of the air duct facing the upper cover of the air duct, and a slot is provided on the upper cover of the air duct for the hook to extend into.

[0009] A further technical solution involves providing a hot air vent on the lower cover of the air duct. This hot air vent connects the frying barrel and the air outlet.

[0010] A further technical solution involves providing a through hole in the upper cover of the air duct. This through hole connects the air inlet duct and the cavity. The through hole is located on the upper cover of the air duct between the first cold air inlet and the heating element.

[0011] A further technical solution involves providing a mounting hole and a panel on the top of the housing. Along the edge of the mounting hole, a first support portion is provided on the top of the housing to support the panel, and a notch is provided on the first support portion to allow cold air to circulate.

[0012] A further technical solution involves providing a second support portion extending from the wall of the mounting hole, which supports the bottom of the panel. The second support portion also has a notch. The notches on the first and second support portions are staggered to allow cold air to circulate and form a first cold air vent.

[0013] A further technical solution involves providing a reflector within the cavity. The frying barrel is positioned within the reflector, and the air inlet extends into the reflector.

[0014] A further technical solution is that a reflective air outlet is provided on the reflector to connect with the air outlet duct. Corresponding to the reflective air outlet, a folded edge is provided on the inner wall of the reflector.

[0015] A further technical solution is that, corresponding to the second cold air vent, a baffle is provided on the inner wall of the outer casing.

[0016] The beneficial technical effects of this utility model are as follows: (1) The dual-air duct air fryer of this utility model has a first cold air inlet, a second cold air inlet, and a hot air outlet on its outer shell, and an air duct assembly is also provided inside the outer shell. When heating, the fan in the air duct assembly draws in air along the first and second cold air inlets, heats it through the heating element, and then enters the frying drum to heat the food, before flowing out of the outer shell along the hot air outlet. The air inlet of the air duct assembly is directly connected to the cavity. When heating the food, the air flows through the cavity and then enters the air inlet, during which the structure inside the cavity is cooled by air. In addition, the first and second cold air inlets are distributed on the top and sides of the outer shell, increasing the area of ​​the cavity covered by air cooling and improving the air cooling effect. Moreover, the second cold air inlet and the hot air outlet are arranged adjacent to each other, so that the hot air to be discharged from the air duct can be cooled by air while the air flows into the air inlet, avoiding the hot air discharged from the air fryer being too hot, reducing safety hazards and optimizing the user experience. Moreover, this air cooling is achieved by the fan used during heating, eliminating the need for an additional cooling fan, simplifying the structure of the air fryer, and reducing the use and maintenance costs of the air fryer. This also avoids the noise and bulk issues caused by additional cooling fans, further optimizing the user experience.

[0017] (2) Furthermore, the first cold air inlet is set around the mounting hole to achieve circumferential air intake, increase the area of ​​the cavity through which the air flows, and further improve the air cooling effect of the air fryer.

[0018] (3) Furthermore, a baffle is provided on the inner wall of the outer shell corresponding to the second cold air vent. The baffle prevents large dust particles and other debris from entering the air fryer, while guiding the direction of the air flowing in along the second cold air vent to ensure the air cooling efficiency of the air fryer.

[0029] Figure 1 A front view structural schematic diagram of a dual-duct air fryer according to an embodiment of the present disclosure is shown. Figure 2 A top view of a dual-duct air fryer according to an embodiment of the present disclosure is shown. Figure 3 A cross-sectional view at point A is shown of a dual-duct air fryer according to an embodiment of the present disclosure. Figure 4 A cross-sectional view at point B is shown of a dual-duct air fryer according to an embodiment of this disclosure. Please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4The dual-duct air fryer includes an outer shell 1, a frying drum 3 disposed within a cavity 11 of the outer shell 1, and an air duct assembly. A first cold air vent 12 is opened at the top of the outer shell 1, and a second cold air vent 14 and a hot air outlet 13 are adjacent to each other on the side of the outer shell 1. An air inlet duct 63 and an air outlet duct 64 are independently provided within the air duct assembly. One end of the air inlet duct 63 connects to the cavity 11, and the other end of the air inlet duct 63 connects to the frying drum 3. A fan 5 and a heating element 71 are disposed within the air inlet duct 63. In some embodiments, the fan 5 can be a centrifugal or rotary blower, and the heating element 71 can be a mica heating element. During heating, the fan 5 within the air duct assembly draws in air along the first cold air vent 12 and the second cold air vent 14, which, after being heated by the heating element 71, enters the frying drum 3 to heat the food, and then flows out of the outer shell 1 along the hot air outlet 13. The air inlet duct 63 of the air duct assembly is directly connected to the cavity 11. When heating food, air flows through the cavity 11 and then into the air inlet duct 63, during which the air cools the structure inside the cavity 11. Additionally, the first cold air inlet 12 and the second cold air inlet 14 are distributed on the top and sides of the outer shell 1, increasing the area of ​​the cavity 11 covered by air cooling and improving the cooling effect. The air outlet duct 64 connects to the fryer and simultaneously covers and connects to the hot air outlet 13. The second cold air inlet 14 and the hot air outlet 13 are arranged adjacent to each other, allowing air to flow into the air inlet duct 63 while simultaneously cooling the hot air preparing to be discharged from the air outlet duct 64, preventing the hot air discharged from the air fryer from being too hot, reducing safety hazards, and optimizing the user experience. Furthermore, this air cooling is achieved by the fan 5 used during heating, eliminating the need for an additional cooling fan, simplifying the structure of the air fryer, and reducing the cost of use and maintenance. It also avoids the noise and bulk issues associated with additional cooling fans, further optimizing the user experience.

[0030] In some embodiments, the air duct cover 6 may also have holes (not shown in the figure) connecting the air inlet duct 63 and the air outlet duct 64. Some of the cold air in the air inlet duct 63 can flow directly into the air outlet duct 64 through the holes to mix with the hot air, lowering the temperature of the hot air in the air outlet duct 64, preventing the hot air discharged from the air fryer from being too hot, reducing safety hazards, and optimizing the user experience. Figure 5 A schematic diagram of the internal structure of a dual-duct air fryer according to an embodiment of the present disclosure is shown in a top view. Figure 6 A partially enlarged view at point C is shown of a dual-duct air fryer according to an embodiment of this disclosure. Please refer to... Figure 4 , Figure 5 and Figure 6The air duct assembly includes an upper air duct cover 6 and a lower air duct cover 7. The upper air duct cover 6 and the lower air duct cover 7 are coupled to form an air inlet duct 63 and an air outlet duct 64. In some embodiments, a hook 72 extends from the side of the lower air duct cover 7 toward the upper air duct cover 6, and a slot 61 is provided on the upper air duct cover 6 for the hook 72 to extend into, positioning and connecting the upper air duct cover 6 and the lower air duct cover 7. Additionally, screws (not shown in the figure) can be provided between the upper air duct cover 6 and the lower air duct cover 7 to completely secure them. The upper air duct cover 6 and the lower air duct cover 7 can also be fixed to the housing 1 by screws.

[0031] Preferably, a hot air inlet 73 is provided on the lower cover 7 of the air duct. The hot air inlet 73 connects the frying barrel 3 and the air outlet 64. A through hole 62 is provided on the upper cover 6 of the air duct. The through hole 62 connects the air inlet 63 and the cavity 11. The through hole 62 is located on the upper cover 6 of the air duct between the first cold air inlet 12 and the heating element 71. When the fan 5 is started, negative pressure may be generated in the air inlet 63 due to the rapid flow of air. The through hole 62 can introduce air into the air inlet 63 to balance the negative pressure. During heating, the air pressure in the air inlet 63 may increase due to the effect of thermal expansion and contraction. The through hole 62 can discharge some of the air in the air inlet 63 to reduce the pressure in the air inlet 63.

[0032] Figure 7 A partially enlarged view at point D is shown of a dual-duct air fryer according to an embodiment of this disclosure. Please refer to... Figure 3 , Figure 4 , Figure 5 and Figure 7 The top of the outer casing 1 has a mounting hole 15 and a panel 4. Along the edge of the mounting hole 15, a first support portion 151 supports the panel 4 on the top of the outer casing 1. A notch is provided on the first support portion 151 to allow cold air to circulate. Cold air can enter the cavity 11 around the mounting hole 15, achieving circumferential air intake, increasing the area of ​​the cavity 11 through which air flows, and improving the air-cooling effect of the air fryer. In some embodiments, the notch may only be formed at a partial angle around the mounting hole 15 to flexibly adjust the position of the first cold air inlet 12 that draws in air. This application does not limit the angle or number of notches.

[0033] Preferably, a second support portion 152 extends from the wall of the mounting hole 15, supporting the bottom of the panel 4. A notch is also provided on the second support portion 152. The notches on the first support portion 151 and the second support portion 152 are staggered to allow cold air to circulate, forming a first cold air vent 12. The staggered arrangement of the notches on the first support portion 151 and the second support portion 152 prevents large particles of dust and other debris from entering the air fryer, while also preventing air from rushing into the cavity 11 and creating a strong, one-point draft, allowing the airflow to flow evenly into the cavity 11.

[0034] More preferably, a baffle 141 is provided on the inner wall of the outer shell 1 corresponding to the second cold air vent 14. The baffle 141 prevents large particles of dust and other debris from entering the air fryer and avoids air rushing into the cavity 11 to form a strong single point of airflow. At the same time, it can guide the direction of the air flowing in along the second cold air vent 14 to ensure its air cooling efficiency for the air fryer.

[0035] Please refer to Figure 3 and Figure 4 A reflector 2 is also installed inside the cavity 11. The frying drum 3 is placed inside the reflector 2, and the air inlet duct 63 extends into the reflector 2. The reflector 2 can be made of metal. The reflector 2 reflects the heat that would otherwise dissipate to the outside of the frying drum 3, reducing heat loss. At the same time, the reflector 2 isolates the frying drum 3 from the cavity 11, reducing the temperature inside the cavity 11 and protecting the components inside the cavity.

[0036] Specifically, a reflective air outlet 22 is provided on the reflector 2 to align with the hot air outlet 73 of the air duct to connect to the air outlet 64. Corresponding to the reflective air outlet 22, a folded edge 21 is also provided on the inner wall of the reflector 2. The folded edge 21 prevents hot air from flowing directly into the air outlet 64 along the reflective air outlet 22, thereby extending the time for the hot air to heat the food and making full use of the heat of the hot air.

[0037] The specific workflow of this utility model is as follows: When heating the food, the fan 5 and the heating element 71 are activated. Air is drawn in by the fan 5 along the air inlet duct 63. Air from outside the outer casing 1 enters the cavity 11 through the first cold air inlet 12 and the second cold air inlet 14, passes over the upper cover 6 and lower cover 7 of the air duct, and then enters the air inlet duct 63. It is then heated by the heating element 71 and finally enters the reflector 2 to heat the food inside the frying drum 3. The heated air then enters the air outlet duct 64 through the air guide holes and the hot air inlet 73, and finally flows out of the outer casing 1 through the hot air outlet 13.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
