Description

Technical Field

[0001] This utility model relates to the field of air fryer technology, specifically a double-layer air fryer. Background Technology

[0002] Air fryers, as a healthy kitchen appliance, are popular among consumers for their ability to bake and fry food using high-temperature air circulation. However, most air fryers on the market are single-layered, processing only one dish at a time, resulting in low efficiency and failing to meet the needs of large families or those requiring the simultaneous processing of multiple foods. To address the low efficiency of single-layer air fryers, some manufacturers have developed double-layered air fryers. Traditional double-layered air fryers typically use a top- or bottom-mounted motor design. In double-layered air fryers, the air inlet is usually located at the bottom or rear of the fryer. Cooling air must travel a long distance to reach the motor and heating element to dissipate heat, leading to high air resistance, low efficiency, and a tendency for the motor to overheat, affecting its lifespan. Furthermore, accumulated heat is conducted to the outer shell of the fryer, causing excessive surface temperature rise and posing a risk of burns. Therefore, a new double-layered air fryer is needed to meet current usage needs. Utility Model Content

[0003] This invention provides a double-layer air fryer, which solves the problem that the air inlet of traditional double-layer air fryers is mostly located at the bottom or rear of the fryer. The cooling air has to travel a long distance to reach the motor and heating element to carry away the heat, resulting in high wind resistance, low efficiency, and easy overheating of the motor, which affects the motor's lifespan.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a double-layer air fryer, comprising an upper fryer body and a lower fryer body, and corresponding upper and lower receiving cavities. The upper and lower fryer bodies are connected by a connecting shell. A first air inlet is provided around the lower end of the connecting shell along its outer periphery, and the first air inlet is used to guide air into the fryer body. A first motor mounting cover is provided at the upper end of the lower fryer body, and a first motor and a first cooling fan are mounted on the first motor mounting cover. A first heating tube and a first fan for generating circulating airflow are provided at the top of the lower receiving cavity. A second motor mounting cover is provided at the upper end of the upper fryer body. The second motor mounting cover is equipped with a second motor and a second cooling fan. The upper surface of the upper fryer body is equipped with a panel shell. The upper outer periphery of the panel shell is provided with multiple second air inlets. The lower end of the connecting shell is provided with a ring of first air inlets around the outer periphery, which can guide external cold air to enter evenly from the first air inlets and directly dissipate heat for the first motor. The second air inlets guide external cold air to enter evenly and directly dissipate heat for the second motor. The double-layer independent housing design can process two different foods or two portions of the same food at the same time, greatly improving cooking efficiency. The upper and lower layers are equipped with independent heating tubes and circulating fans, which can make hot air circulate fully in the housing and ensure that the food is heated evenly from all directions.

[0005] As a supplement to the technical solution described in this utility model, both the upper and lower accommodating cavities are provided with frying baskets with open tops. The frying baskets are adapted to the inner walls of the corresponding upper and lower accommodating cavities to form hot air gaps, which facilitates the full circulation of hot air around the frying baskets and ensures that the food is heated from all directions.

[0006] As a supplement to the technical solution described in this utility model, the front ends of the first motor mounting cover and the second motor mounting cover are both provided with downwardly inclined air guides, and the rear ends are both provided with heat dissipation vents. The air guides can guide the airflow to flow in a directional manner into the upper and lower receiving cavities, and the heat dissipation vents are used to dissipate heat and improve heat dissipation efficiency.

[0007] As a supplement to the technical solution described in this utility model, the bottom of the lower receiving cavity is provided with a downwardly recessed cavity, and a third heating tube is provided in the cavity, forming a double heating structure, which further improves the heating efficiency and uniformity of the lower layer.

[0008] As a supplement to the technical solution described in this utility model, the panel shell is L-shaped, and a control panel is provided at the front end of the panel shell to facilitate user operation and control of the operating parameters of the upper and lower fryers.

[0009] As a supplement to the technical solution described in this utility model, the inner wall of the connecting shell is provided with multiple snap-fit ​​protrusions, and the lower side of the outer shell of the upper fryer body is provided with a corresponding snap-fit ​​groove, which makes installation and disassembly convenient and facilitates equipment maintenance.

[0010] As a supplement to the technical solution described in this utility model, a third air inlet is provided on the bottom shell of the lower fryer body. During the hot air circulation process in the lower cavity, cold air is directly guided into the lower cavity through the third air inlet to replenish the loss of hot air flow. At the same time, the third heating tube and surrounding structure in the lower bottom cavity are cooled down, and the heat generated by the bottom heating component is removed, avoiding local heat accumulation and extending the life of the component.

[0011] As a supplement to the technical solution described in this utility model, ventilation holes are provided at the upper rear ends of the upper and lower accommodating cavities. The ventilation holes connect the upper accommodating cavity with the inner cavity of the second motor mounting cover and the lower accommodating cavity with the inner cavity of the first motor mounting cover, forming a heat dissipation channel to ensure that the heat inside the machine body is quickly discharged.

[0012] As a supplement to the technical solution described in this utility model, the top of the upper cavity is provided with a second heating tube and a second fan for generating circulating airflow, which can quickly heat the air in the upper cavity and form a circulation, ensuring that the upper food is heated evenly.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This air fryer combines independent cooking in two layers, efficient heat dissipation, and uniform heating. Its dual-layer independent chamber design allows for the simultaneous processing of two different foods or two portions of the same food, significantly improving cooking efficiency. Both the upper and lower layers are equipped with independent heating elements and circulating fans, ensuring thorough circulation of hot air within the chambers. This guarantees even heating of the food from all sides, preventing undercooked or burnt areas. The first and second air inlets guide external cold air into the fryer body, directly dissipating heat from the first and second motors and extending their lifespan. This design addresses the problem of traditional double-layer air fryers where the air inlets are often located at the bottom or rear of the fryer, requiring cooling air to travel a long distance to the motors and heating elements to remove heat, resulting in high air resistance, low efficiency, and potential motor overheating, thus affecting motor lifespan.

[0028] 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.

[0029] The embodiments of this utility model relate to a double-layer air fryer, such as... Figure 1-11As shown, the fryer includes an upper fryer body 1 and a lower fryer body 2, and corresponding upper and lower receiving cavities 3 and 4. The upper fryer body 1 and the lower fryer body 2 are connected by a connecting housing 5, which forms a cold air cavity. A first air inlet 6 is provided around the lower end of the connecting housing 5 along its outer periphery, which guides air into the cold air cavity. A first motor mounting cover 7 is provided at the upper end of the lower fryer body 2, and a first motor 8 and a first cooling fan 9 are mounted on the first motor mounting cover 7. A first heating tube 10 and a first fan 11 for generating circulating airflow are provided at the top of the lower receiving cavity 4. A second motor mounting cover 20 is provided at the upper end of the upper fryer body 1, and a second motor 1 is mounted on the second motor mounting cover 20. 2. A second cooling fan 13 is provided. A panel housing 14 is installed on the upper end of the upper fryer body 1. Multiple second air inlets 16 are provided on the upper outer periphery of the panel housing 14. A second ventilation port 31 is provided at the lower front of the upper fryer body 1. The second ventilation port 31 connects the upper receiving cavity 3 with the cold air cavity of the connecting housing 5. The first air inlet 6 can guide the external cold air to enter evenly and directly dissipate heat for the first motor 8. The second air inlet 16 can guide the external cold air to enter evenly and directly dissipate heat for the second motor 12. The double-layer independent receiving cavity design can process two different foods or two portions of the same food at the same time, greatly improving cooking efficiency. The upper and lower layers are equipped with independent heating tubes and circulating fans, which can make hot air circulate fully in the receiving cavity and ensure that the food is heated evenly from all directions.

[0030] In this embodiment, as Figure 1 As shown, both the upper cavity 3 and the lower cavity 4 are equipped with frying baskets 17 with open tops. The frying baskets 17 are adapted to the inner walls of the corresponding upper cavity 3 and lower cavity 4 to form hot air gaps, which facilitates the full circulation of hot air around the frying baskets and ensures that the food is heated from all directions.

[0031] In this embodiment, as Figure 6 and Figure 9 As shown, the first motor mounting cover 7 and the second motor mounting cover 20 are provided with a flow guide shell 29 on their front side. One end of the flow guide shell 29 is provided with an inclined surface. The front part of the flow guide shell 29 is provided with a plurality of first ventilation holes 30. The front ends of the first motor mounting cover 7 and the second motor mounting cover 20 are provided with downwardly inclined air guides 18. The air guides 18 cooperate with the inclined surface of the flow guide shell 29 and the first ventilation holes 30 to guide the airflow to flow in a directional direction into the upper receiving cavity 3 and the lower receiving cavity 4. The rear ends of the first motor mounting cover 7 and the second motor mounting cover 20 are provided with heat dissipation holes 19. The heat dissipation holes 19 are used to dissipate heat and improve heat dissipation efficiency.

[0032] In this embodiment, as Figure 3As shown, the bottom of the lower receiving cavity 4 is provided with a downwardly recessed cavity 21, and a third heating tube 22 is provided in the cavity 21, forming a double heating structure at the top and bottom, which further improves the heating efficiency and uniformity of the lower layer.

[0033] In this embodiment, as Figure 10 As shown, the panel housing 14 is L-shaped, and a control panel 15 is provided at the front end of the panel housing 14 to facilitate user operation and control of the operating parameters of the upper and lower fryers.

[0034] In this embodiment, as Figure 8 and Figure 10 As shown, the inner wall of the connecting housing 5 is provided with multiple snap-fit ​​protrusions 23, and the lower side of the outer housing of the upper fryer body 1 is provided with a snap-fit ​​groove 24. The snap-fit ​​groove 24 and the snap-fit ​​protrusions 23 cooperate to fix the outer housing of the upper fryer body 1 and the connecting housing 5. The connecting housing 5 is connected to the outer housing of the lower fryer body 2 and the bottom of the upper fryer body 1 by bolts. The installation and disassembly are convenient and the equipment is easy to maintain.

[0035] In this embodiment, as Figure 2 As shown, a third air inlet 25 is provided on the bottom shell of the lower fryer body 2. During the hot air circulation in the lower receiving cavity 4, cold air is directly guided into the lower cavity 4 through the third air inlet 25 to replenish the loss of hot air flow. At the same time, the third heating tube 22 and the surrounding structure in the lower bottom cavity 21 are cooled down, and the heat generated by the bottom heating component is removed, avoiding local heat accumulation and extending the life of the component.

[0036] In this embodiment, as Figure 5 As shown, ventilation holes 26 are provided at the upper rear end of the upper cavity 3 and the lower cavity 4. The ventilation holes 26 connect the upper cavity 3 with the inner cavity of the second motor mounting cover 20 and the lower cavity 4 with the inner cavity of the first motor mounting cover 7, so as to realize the smooth flow of internal and external gases, form a heat dissipation channel, and ensure that the heat inside the machine body is quickly discharged.

[0037] In this embodiment, as Figure 2 As shown, the top of the upper cavity 3 is provided with a second heating tube 27 and a second fan 28 for generating circulating airflow, which can quickly heat the air in the upper cavity 3 and form a circulation, ensuring that the upper food is heated evenly.

[0038] In this embodiment, as Figure 1As shown, during use, the user sets the temperature and time of the upper and lower fryers respectively through the control panel 15. The first motor 8 and the second motor 12 start, driving the first fan 11, the second fan 28, the first cooling fan 9, and the second cooling fan 13. External cold air enters the machine body through the first air inlet 6 at the lower end of the connecting shell 5 and the second air inlet 16 at the upper end of the panel shell 14. The cold air entering the machine body is divided into two paths. One path is a cooling airflow, which, under the action of the first cooling fan 9 and the second cooling fan 13, enters the inner cavity of the first motor mounting cover 7 and the second motor mounting cover 20 to cool the first motor 8 and the second motor 12. The cooled hot air then mixes with the hot air and is directly discharged from the heat dissipation port 19. The other path of cold air is guided by the air guide 18 in conjunction with the inclined surface of the guide shell 29 and the first vent 30 to direct the airflow to the upper receiving cavity 3 and the lower receiving cavity 4. Under the action of the first heating tube 10, the second heating tube 27, and the third heating tube 22, a heating airflow is formed. Driven by the first fan 11 and the second fan 28, a circulating airflow is formed to achieve all-round wrapping and heating of the food. During cooking, moisture and excess heat are discharged through the ventilation holes 26 and heat dissipation vents 19 at the upper rear of the cavity.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly.
