Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances, and in particular to a safe air fryer. Background Technology

[0002] As people's living standards improve, their cooking methods are becoming more diverse. Most air fryers currently available are single-cavity air fryers. Because of their fixed cooking cavity structure, these air fryers can only cook one type of food at a time, resulting in low cooking efficiency and failing to meet the diverse cooking needs of users. In addition, these air fryers usually have an air vent connected to the cooking cavity to expel excess circulating heat. Directly expelling this circulating heat can easily cause external objects or walls to overheat, and can also cause burns to users, resulting in poor user safety and a poor user experience. Utility Model Content

[0003] This application provides a safe air fryer to solve the technical problems of low cooking efficiency, poor user safety, and unsatisfactory user experience of existing air fryers.

[0004] To solve the above-mentioned technical problems, this utility model provides a safe air fryer, including a body. The body has a cooking chamber, and a circulating blower chamber and a cooling chamber are arranged sequentially on the rear side of the cooking chamber. The circulating blower chamber is connected to the cooking chamber. A circulating fan is provided in the circulating blower chamber. A hot air outlet is provided on the side wall of the circulating blower chamber opposite to the circulating fan. An exhaust port is provided on the side wall of the body opposite to the hot air outlet. An air outlet channel is provided in the body, connecting the hot air outlet and the exhaust port. A cooling fan is provided in the cooling chamber, and a cold air outlet is provided in the cooling chamber, connecting the air outlet channel. The air fryer, by providing an air outlet channel at the rear of the cooking chamber, can expel excess circulating heat from the cooking chamber. Simultaneously, by connecting the heat dissipation chamber to the air outlet channel, the cooling airflow generated by the cooling fan within the heat dissipation chamber can dissipate heat from the circulating heat in the air outlet channel, thereby reducing the temperature of the exhaust airflow. This not only prevents overheating of the external walls and / or objects of the unit but also reduces the risk of burns to the user, effectively improving user safety and experience.

[0005] In an optional embodiment, the cooking cavity includes a first cooking cavity and a second cooking cavity arranged vertically at intervals. A first circulating air chamber and a first cooling air chamber are sequentially arranged on the rear side of the first cooking cavity. The first circulating air chamber communicates with the first cooking cavity. A first circulating fan is provided in the first circulating air chamber. A first hot air outlet is provided on the side wall of the first circulating air chamber opposite to the first circulating fan. A first exhaust port is provided on the side wall of the body corresponding to the first hot air outlet. A first air outlet channel communicating between the first hot air outlet and the first exhaust port is provided in the body. A first cooling fan is provided in the first cooling air chamber. A first cold air outlet is connected to the first air outlet channel; a second circulating blower cavity and a second heat dissipation cavity are sequentially provided on the rear side of the second cooking cavity. The second circulating blower cavity is connected to the second cooking cavity. A second circulating fan is provided in the second circulating blower cavity. A second hot air outlet is provided on the side wall of the second circulating blower cavity opposite to the second circulating fan. A second exhaust port is provided on the side wall of the body corresponding to the second hot air outlet. A second air outlet channel is provided in the body, connecting the second hot air outlet and the second exhaust port. A second heat dissipation fan is provided in the second heat dissipation cavity. A second cold air outlet is provided in the second heat dissipation cavity, connecting the second air outlet channel. The air fryer features two cooking chambers arranged vertically and horizontally within its body. This allows for the simultaneous cooking of multiple foods to meet diverse user needs, effectively improving cooking efficiency. It also reduces the kitchen space occupied by the air fryer, thus increasing kitchen space utilization and enhancing the user experience. Furthermore, two cooling vents are located behind each cooking chamber, allowing for the separate dissipation of heat from the two chambers, effectively lowering the overall temperature. Additionally, two air outlets are located behind each cooking chamber and connected to the cooling vents. This allows for the separate exhaust of circulating heat from the two cooking chambers, improving exhaust efficiency, and also allows for the separate dissipation of heat from the cooling vents into the air outlets, reducing the temperature of the exhaust air and minimizing the risk of burns, thus enhancing user safety.

[0006] In an optional embodiment, the first cooling fan is provided with a first enclosure forming at least a portion of the first cooling air cavity, and the first cold air outlet is disposed on the first enclosure; the second cooling fan is provided with a second enclosure forming at least a portion of the second cooling air cavity, and the second cold air outlet is disposed on the second enclosure. The first and second enclosures are adapted to guide airflow. By providing the first and second enclosures on the outside of the first and second cooling fans respectively, the cooling airflow generated by the first and second cooling fans can be collected and discharged from the first and second cold air outlets respectively, thereby dissipating the circulating heat flow in the first and second air outlet channels. This not only effectively improves the cooling efficiency and cooling effect of the first and second cooling fans, but also effectively reduces the temperature of the exhaust airflow in the first and second air outlet channels, thus avoiding burns to users and effectively improving user safety.

[0007] In one optional embodiment, the projections of the first cold air outlet and the first cooling fan on the rotation axis of the first cooling fan at least partially overlap; the projections of the second cold air outlet and the second cooling fan on the rotation axis of the second cooling fan at least partially overlap. This arrangement allows the cooling airflow generated by the first and second cooling fans to enter the first and second air outlet channels more effectively and quickly through the first and second cold air outlets, thereby dissipating the circulating heat flow within the first and second air outlet channels and effectively improving heat dissipation efficiency and effect.

[0008] In an optional embodiment, a first mounting cavity communicating with the first heat dissipation air cavity is provided on the rear side of the first heat dissipation air cavity. A first driving system is provided within the first mounting cavity, and the first driving system is adapted to extend and connect with the first circulating fan and the first cooling fan. Similarly, a second mounting cavity communicating with the second heat dissipation air cavity is provided on the rear side of the second heat dissipation air cavity. A second driving system is provided within the second mounting cavity, and the second driving system is adapted to extend and connect with the second circulating fan and the second cooling fan. By using the same driving system for both the first circulating fan and the first cooling fan, and the same driving system for both the second circulating fan and the second cooling fan, the overall structure of the air fryer is simplified, and its overall volume is reduced, thereby reducing its space occupation and effectively improving the user experience. Furthermore, by using different driving systems for the first circulating fan, the first cooling fan, the second circulating fan, and the second cooling fan, simultaneous cooking in both cooking cavities is possible, as is individual cooking in either of the two cooking cavities, thus meeting diverse user cooking needs and effectively improving the user experience.

[0009] In an optional embodiment, the rear side of the housing is provided with a first cold air inlet and a second cold air inlet, which are respectively connected to the first mounting cavity and the second mounting cavity. The first cold air inlet and the second cold air inlet are adapted to correspond to at least a portion of the first drive system and the second drive system. By providing the first cold air inlet and the second cold air inlet on the housing, which are respectively connected to the first mounting cavity and the second mounting cavity, and setting the first cold air inlet and the second cold air inlet to correspond to the first drive system and the second drive system, it is possible not only to use the first cooling fan and the second cooling fan to draw external cold air into the first mounting cavity and the second mounting cavity, thereby dissipating heat from the control system, drive system and other electrical components in the first mounting cavity and the second mounting cavity, but also to allow the external cold air to come into contact with the first drive system and the second drive system more quickly after entering the first mounting cavity and the second mounting cavity through the first cold air inlet and the second cold air inlet, thereby dissipating heat from the first drive system and the second drive system, effectively improving heat dissipation efficiency and effect.

[0010] In an optional embodiment, the rear side of the body is provided with a protrusion for covering the first drive system and the second drive system and protruding outward. The first cold air inlet and the second cold air inlet are provided on the protrusion and are located behind the protrusion. The two sides of the rear sidewall of the body are provided with vertically extending arc-shaped transition surfaces adjacent to the protrusion. The first exhaust port and the second exhaust port are provided vertically spaced on the transition surface. The air fryer features a protrusion on the rear side of the body, with the first and second cold air inlets located behind it. This not only conceals the first and second cold air inlets, improving the overall aesthetics of the unit, but also increases the gap between the first and second drive systems and the outer shell. This allows external cold air to enter the first and second mounting cavities through the first and second cold air inlets, providing better and more comprehensive heat dissipation for the drive systems, effectively improving heat dissipation efficiency and effect. Simultaneously, by placing the first and second exhaust vents on the rear side of the unit, adjacent to the protrusion, not only are the first and second exhaust vents concealed, further enhancing the overall aesthetics, but the first and second cooling fans also drive the flow of external cold air, mixing it with the circulating hot air exhausted from the first and second exhaust vents. This reduces the temperature of the exhaust air from the first and second exhaust vents, preventing burns to the user and effectively improving user safety.

[0011] In an optional embodiment, the body is provided with an air outlet assembly made of a high-temperature resistant material. The air outlet assembly includes a first air outlet assembly and a second air outlet assembly. The first air outlet assembly has a first air outlet channel, and the second air outlet assembly has a second air outlet channel. By providing the first and second air outlet assemblies made of high-temperature resistant material within the body, not only can independent air outlets be achieved for the first and second cooking chambers, effectively improving air outlet efficiency, but the impact of circulating heat flow on the first and second air outlet assemblies can also be reduced, effectively improving the air outlet stability of the first and second air outlet assemblies and the performance stability of the air fryer.

[0012] In one optional embodiment, the first air outlet component and the second air outlet component are adapted to be a one-piece molded structure. By setting the first air outlet component and the second air outlet component as a one-piece molded structure, not only can the overall structure of the air fryer be simplified, but the structural integrity of the air fryer can also be improved, thereby enhancing the performance stability and reliability of the air fryer and effectively improving the user experience.

[0013] In an optional embodiment, the machine body is provided with a heat dissipation duct communicating with the heat dissipation cavity. The heat dissipation duct is adapted to surround at least a portion of the cooking cavity. A first vent and a second vent communicating with the atmosphere are respectively provided at both ends of the heat dissipation duct. The first vent is located around the top periphery of the machine body, and the second vent is located at the bottom of the machine body. By providing the heat dissipation duct within the machine body and surrounding at least a portion of the cooking cavity, the cooling airflow within the duct can dissipate heat from the cooking cavity. This not only reduces the outward transfer of high temperatures from the cooking cavity, thus reducing the impact on the normal operation of external electrical components, but also prevents the machine body from overheating and causing burns to the user, effectively improving user safety. Simultaneously, by placing the second vent at the bottom of the machine body and surrounding the first vent at the top, the second vent can be concealed, improving the overall aesthetics of the air fryer. Furthermore, more external cold air can enter the heat dissipation duct through the first vent, thereby dissipating heat from the machine body and effectively improving the air fryer's heat dissipation efficiency.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] This application, by providing the air outlet channel at the rear of the cooking cavity, can discharge excess circulating heat flow within the cooking cavity. Simultaneously, by connecting the heat dissipation air cavity to the air outlet channel, the cooling airflow generated by the cooling fan within the heat dissipation air cavity can dissipate heat from the circulating heat flow within the air outlet channel, thereby reducing the temperature of the airflow discharged from the exhaust port. This not only prevents overheating of the external walls and / or objects of the unit but also reduces the risk of burns to the user, effectively improving user safety and user experience.

[0027] Appendix Figure 1 To be continued Figure 5The diagram shown is a schematic of a safe air fryer provided by this utility model. The air fryer includes a body 10, within which a cooking chamber 11 is provided. A circulating air chamber 12 and a cooling air chamber 13 are sequentially arranged at the rear of the cooking chamber 11. The circulating air chamber 12 is connected to the cooking chamber 11. A circulating fan 20 for generating circulating airflow is provided in the circulating air chamber 12. A heating component 30 is provided along the airflow circulation path of the circulating fan 20, and the heating component 30 is adapted to heat the circulating airflow to form… A circulating hot air stream heats the food inside the cooking cavity 11. A hot air outlet 121 is provided on the side wall of the circulating blower 12 opposite to the circulating fan 20. An exhaust vent 14 is provided on the side wall of the body 10 corresponding to the hot air outlet 12. An air outlet channel 15 connects the hot air outlet 12 and the exhaust vent 14 within the body 10. A cooling fan 40 for generating a cooling air stream is provided in the cooling air cavity 13. The cooling air cavity 13 has a cold air outlet 131 connecting to the air outlet channel 15. When the air fryer is in use, at least a portion of the circulating hot air stream in the cooking cavity 11 enters the air outlet channel 15 through the hot air outlet 121, mixes with the cooling air stream generated by the cooling fan 40, and is then discharged from the exhaust vent 14. Therefore, by providing the air outlet duct 15 at the rear of the cooking chamber 11, the air fryer can discharge excess circulating heat flow within the cooking chamber 11. Simultaneously, by connecting the heat dissipation chamber 13 to the air outlet duct 15, the cooling airflow generated by the cooling fan 40 within the heat dissipation chamber 13 can dissipate heat from the circulating heat flow within the air outlet duct 15, thereby reducing the temperature of the airflow discharged from the exhaust vent 14. This not only prevents overheating of the external walls and / or objects of the unit 10 but also reduces the risk of burns to the user, effectively improving user safety and user experience.

[0028] like Figure 1 and Figure 2As shown, in an optional embodiment, the cooking cavity 11 includes a first cooking cavity 111 and a second cooking cavity 112 arranged vertically at intervals. A first circulating air chamber 122 and a first heat dissipation air chamber 132 are sequentially arranged on the rear side of the first cooking cavity 111. The first circulating air chamber 122 communicates with the first cooking cavity 111. A first circulating fan 21 is provided in the first circulating air chamber 122, and a first heating element 31 is provided on the airflow circulation path of the first circulating fan 21. A first hot air outlet 1211 is provided on the side wall of the first circulating air chamber 122 opposite to the first circulating fan 21. A first exhaust vent 141 is provided on the side wall of the body 10 corresponding to the first hot air outlet 1211. A first air outlet duct 151 communicating between the first hot air outlet 1211 and the first exhaust vent 141 is provided in the body 10. A first cooling fan 41 is provided in the first heat dissipation air chamber 132, and the first heat dissipation air chamber 132 is connected to... The first air outlet 151 has a first cold air outlet 1311; the rear side of the second cooking cavity 112 is provided with a second circulating blower cavity 123 and a second heat dissipation cavity 133 in sequence. The second circulating blower cavity 123 is connected to the second cooking cavity 112. The second circulating blower cavity 123 is provided with a second circulating fan 22. The airflow circulation path of the second circulating fan 22 is provided with a second heating component 32. The side wall of the second circulating blower cavity 123 opposite to the second circulating fan 22 is provided with a second hot air outlet 1212. The side wall of the body 10 corresponding to the second hot air outlet 1212 is provided with a second exhaust port 142. The body 10 is provided with a second air outlet 152 connecting the second hot air outlet 1212 and the second exhaust port 142. The second heat dissipation cavity 133 is provided with a second heat dissipation fan 42. The second heat dissipation cavity 133 is provided with a second cold air outlet 1312 connecting the second air outlet 152.The air fryer, with two cooking chambers arranged vertically and horizontally within its body 10, can simultaneously cook multiple foods to meet diverse user needs and effectively improve cooking efficiency. It also reduces the kitchen space occupied by the air fryer, thereby increasing kitchen space utilization and enhancing the user experience. Furthermore, the air fryer features two cooling vents behind each cooking chamber, allowing the cooling airflow within these vents to dissipate heat from both chambers, effectively lowering the temperature of the body 10. Additionally, the air fryer has two air outlet channels behind each cooking chamber, connected to the two cooling vents. This allows for the separate discharge of circulating heat from each cooking chamber, improving heat dissipation efficiency, and also allows the cooling airflow from the cooling vents to dissipate heat from the airflow in the air outlet channels, reducing the temperature of the exhaust air and minimizing the risk of burns, thus improving user safety.

[0029] like Figure 4 As shown, in an optional embodiment, the first cooling fan 41 is provided with a first enclosure 1321 forming at least part of the first cooling air cavity 132 on its outer side, and the first cold air outlet 1311 is provided on the first enclosure 1321; the second cooling fan 42 is provided with a second enclosure 1331 forming at least part of the second cooling air cavity 133 on its outer side, and the second cold air outlet 1312 is provided on the second enclosure 1331. The first enclosure 1321 and the second enclosure 1331 are adapted to guide airflow. By setting the first enclosure 1321 and the second enclosure 1331 on the outside of the first cooling fan 41 and the second cooling fan 42 respectively, the cooling airflow generated by the first cooling fan 41 and the second cooling fan 42 can be collected and discharged from the first cold air outlet 1311 and the second cold air outlet 1312 respectively to dissipate the circulating heat flow in the first air outlet channel 151 and the second air outlet channel 152. This not only effectively improves the heat dissipation efficiency and effect of the first cooling fan 41 and the second cooling fan 42, but also effectively reduces the temperature of the airflow discharged in the first air outlet channel 151 and the second air outlet channel 152, thereby avoiding burns to users and effectively improving user safety.

[0030] like Figure 4As shown, in an optional embodiment, the projections of the first cold air outlet 1311 and the first cooling fan 41 on the rotation axis of the first cooling fan 41 at least partially overlap; the projections of the second cold air outlet 1312 and the second cooling fan 412 on the rotation axis of the second cooling fan 42 at least partially overlap. This arrangement allows the cooling airflow generated by the first cooling fan 41 and the second cooling fan 42 to enter the first air outlet 151 and the second air outlet 152 more effectively and quickly through the first cold air outlet 1311 and the second cold air outlet 1312, thereby dissipating the circulating heat flow in the first air outlet 151 and the second air outlet 152, effectively improving the heat dissipation efficiency and effect.

[0031] like Figure 2 and Figure 4 As shown, in an optional embodiment, a mounting cavity 16 is provided on the rear side of the heat dissipation cavity 13. A drive system 50 is provided within the mounting cavity 16, and the drive system 50 is adapted to extend and drive to connect with the circulating fan 20 and the heat dissipation fan 40. Specifically, the mounting cavity 16 includes a first mounting cavity 161 located on the rear side of the first heat dissipation cavity 132 and communicating with it, and a second mounting cavity 162 located on the rear side of the second heat dissipation cavity 133 and communicating with it. The first mounting cavity 161 is provided with a first drive system 51, which is adapted to extend and drive to connect with the first circulating fan 21 and the first heat dissipation fan 41. The second mounting cavity 162 is provided with a second drive system 52, which is adapted to extend and drive to connect with the second circulating fan 22 and the second heat dissipation fan 42. By using the same drive system to drive the first circulating fan 21 and the first cooling fan 41, and the same drive system to drive the second circulating fan 22 and the second cooling fan 42, the overall structure of the air fryer can be simplified, and the overall volume of the air fryer can be reduced, thereby reducing the space occupied by the air fryer and effectively improving the user experience. At the same time, by using different drive systems to drive the first circulating fan 21, the first cooling fan 41, the second circulating fan 22, and the second cooling fan 42, simultaneous cooking in both cooking chambers can be achieved, as well as individual cooking in either of the two cooking chambers, thereby meeting the diverse cooking needs of users and effectively improving the user experience.

[0032] like Figures 2 to 4As shown, in an optional embodiment, the rear side of the body 10 is provided with a cold air inlet 17 that communicates with the mounting cavity 16. The cold air inlet 17 includes a first cold air inlet 171 and a second cold air inlet 172 that are spaced apart vertically and communicate with the first mounting cavity 161 and the second mounting cavity 162 respectively. The first cold air inlet 171 and the second cold air inlet 172 are adapted to correspond to at least a portion of the first drive system 51 and the second drive system 52. By providing a first cold air inlet 171 and a second cold air inlet 172 on the body 10, respectively connecting the first mounting cavity 161 and the second mounting cavity 162, and setting the first cold air inlet 171 and the second cold air inlet 172 to correspond to the first drive system 51 and the second drive system 52 respectively, it is possible not only to use the first cooling fan 41 and the second cooling fan 42 to draw external cold air into the first mounting cavity 161 and the second mounting cavity 162, thereby dissipating heat from the control system, drive system and other electrical components in the first mounting cavity 161 and the second mounting cavity 162, but also to allow external cold air to enter the first mounting cavity 161 and the second mounting cavity 162 through the first cold air inlet 171 and the second cold air inlet 172, and then come into contact with the first drive system 51 and the second drive system 52 more quickly, thereby dissipating heat from the first drive system 51 and the second drive system 52, effectively improving heat dissipation efficiency and effect.

[0033] like Figures 2 to 4As shown, in an optional embodiment, the rear side of the body 10 is provided with a protrusion 18 for covering the first drive system 51 and the second drive system 52 and protruding outward. The first cold air inlet 171 and the second cold air inlet 172 are provided on the protrusion 18 and are located on the rear side of the protrusion 18. The two sides of the rear sidewall of the body 10 are provided with vertically extending arc-shaped transition surfaces adjacent to the protrusion 18. The first exhaust port 141 and the second exhaust port 142 are provided vertically and vertically on the transition surfaces. The air fryer, by providing a protrusion 18 on the rear side of the body 10 and placing the first cold air inlet 171 and the second cold air inlet 172 on the rear side of the protrusion 18, not only conceals the first cold air inlet 171 and the second cold air inlet 172 to improve the overall aesthetics of the body 10, but also increases the gap between the first drive system 51 and the second drive system 52 and the outer shell of the body 10. This allows external cold air to enter the first mounting cavity 161 and the second mounting cavity 162 through the first cold air inlet 171 and the second cold air inlet 172, resulting in better and more comprehensive heat dissipation for the first drive system 51 and the second drive system 52. This effectively improves heat dissipation efficiency and effect. Furthermore, by arranging the first exhaust vent 141 and the second exhaust vent 142 on the rear side of the body 10, adjacent to the protrusion 18, not only can the first exhaust vent 141 and the second exhaust vent 142 be concealed to enhance the overall aesthetics of the body 10, but the first cooling fan 41 and the second cooling fan 42 can also drive the flow of cool air outside the body 10, thereby mixing it with the circulating heat flow discharged from the first exhaust vent 141 and the second exhaust vent 142. This reduces the temperature of the airflow discharged from the first exhaust vent 141 and the second exhaust vent 142, preventing burns to the user and effectively improving user safety.

[0034] like Figure 5As shown, in an optional embodiment, the body 10 is further provided with an air outlet assembly 19. The air outlet assembly 19 is suitable for being made of high-temperature resistant materials such as PP, PBI, PTFE, and PI. The air outlet assembly 19 includes a first air outlet assembly 191 and a second air outlet assembly 192. The first air outlet assembly 191 is provided with a first air outlet channel 151, and the second air outlet assembly 192 is provided with a second air outlet channel 152. By providing the first air outlet assembly 191 and the second air outlet assembly 192 made of high-temperature resistant materials in the body, not only can independent air outlets of the first cooking cavity 111 and the second cooking cavity 112 be achieved, effectively improving air outlet efficiency, but the influence of circulating heat flow on the first air outlet assembly 191 and the second air outlet assembly 192 can also be reduced, effectively improving the air outlet stability of the first air outlet assembly 191 and the second air outlet assembly 192 and the performance stability of the air fryer.

[0035] like Figure 5 As shown, in an optional embodiment, the first air outlet component 191 and the second air outlet component 192 are adapted to be a one-piece molded structure. By setting the first air outlet component 191 and the second air outlet component 192 as a one-piece molded structure, not only can the overall structure of the air fryer be simplified, but the structural integrity of the air fryer can also be improved, thereby improving the performance stability and reliability of the air fryer and effectively enhancing the user experience.

[0036] like Figure 2 and Figure 3As shown, in an optional embodiment, the body 10 is provided with a heat dissipation duct 60 that connects to the heat dissipation cavity 13. The heat dissipation duct 60 is adapted to surround at least a portion of the cooking cavity 11. The two ends of the heat dissipation duct 60 are respectively provided with a first vent 61 and a second vent 62 that connect to the atmosphere. The first vent 61 is arranged around the top periphery of the body 10, and the second vent 62 is adapted to be located at the bottom of the body 10. By setting the heat dissipation duct 60 inside the body 10 and surrounding at least part of the cooking cavity 11, the cooling airflow within the heat dissipation duct 60 can dissipate heat from the cooking cavity 11. This not only reduces the outward transfer of high temperatures from the cooking cavity 11, thus reducing the impact on the normal operation of external electrical components within the cooking cavity 11, but also prevents the body 10 from overheating and causing burns to the user, effectively improving user safety. Simultaneously, by placing the second vent 62 at the bottom of the body 10 and surrounding the first vent 61 at the top of the body 10, the second vent 62 can be concealed, enhancing the overall aesthetics of the air fryer. Furthermore, more external cold air can enter the heat dissipation duct 60 through the first vent 61, thereby dissipating heat from the body 10 and effectively improving the air fryer's heat dissipation efficiency.
