Description

Technical Field

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

[0002] Air fryers use air as a heat transfer medium, effectively reducing the oil content of food and providing a new option for healthy eating, thus gaining increasing popularity among consumers. However, most air fryers on the market currently only come with a single-sized cooking pot. In actual use, when users need to process different types or quantities of food simultaneously, they often need to purchase multiple devices or cook in batches, which not only increases operating costs and space requirements but also significantly reduces cooking efficiency.

[0003] Therefore, some people have invented multi-cavity air fryers. For example, a double-layer air fryer disclosed in CN 220832770 U includes a fryer body. The cooking cavity inside the fryer body is divided into upper and lower layers by a partition plate. Upper and lower hot air devices are arranged in the cooking cavities corresponding to the upper and lower layers inside the fryer body. The upper hot air device is arranged at the top of the upper cooking cavity, and the lower hot air device is arranged at the back of the lower cooking cavity. An upper fryer body and a lower fryer body are installed in both the upper and lower cooking cavities. The open projection of the upper fryer body covers the upper hot air device, and the side wall of the lower fryer body is provided with ventilation holes corresponding to the lower hot air device.

[0004] However, in existing technologies, multi-cavity cooking is typically achieved by dividing a single cooking cavity into multiple zones. This design has significant shortcomings in practical use: when multiple cooking cavities are working simultaneously, heat can easily conduct between the cavities, causing temperature interference and affecting the consistency of cooking results and the quality of food processing. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes a double-layer air fryer with independent temperature control.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A double-layer air fryer with independent temperature control includes a shell, a first cooking section and a second cooking section are disposed inside the shell, and a heating component for supplying hot air to the first cooking section and the second cooking section. The first cooking section and the second cooking section respectively form a first cooking cavity and a second cooking cavity. The heating component includes a mounting bracket, a heating unit and an exhaust unit disposed on the mounting bracket. The mounting bracket has a first heat insulation groove, the first cooking part and the second cooking part are inserted into the first heat insulation groove, a heat insulation seat is provided between the first cooking part and the second cooking part, the heat insulation seat has a second heat insulation groove, the top of the first cooking part and the bottom of the second cooking part are respectively inserted into the second heat insulation groove.

[0007] Preferably, the first cooking section includes a first side plate, a first bottom plate, and a first top plate, which together form a first cooking cavity. The second cooking section includes a second side plate, a second bottom plate, and a second top plate, which together form a second cooking cavity. Through these improvements, the first and second cooking sections are independently assembled, significantly improving the heat insulation performance and temperature independence of the double-layer fryer. This meets the user's need to cook different ingredients simultaneously while avoiding temperature conduction between the first and second cooking sections, which would affect the cooking effect.

[0008] Preferably, a support positioning plate extends from the mounting bracket, and a plurality of heat insulation columns are inserted into the support positioning plate. The two ends of the heat insulation columns abut against the top of the first base plate and the bottom of the second base plate, respectively. The support positioning plate is inserted into the heat insulation seat. Through the above improvements, since the first cooking part and the second cooking part are independently spliced ​​together, the structural strength can be improved by supporting the second cooking part with heat insulation columns. Furthermore, the support positioning plate inserted into the heat insulation seat can further improve the stability of the heat insulation column installation.

[0009] Preferably, the first top plate has an installation groove, the heat insulation column includes a support section and heat insulation sleeves disposed at both ends of the support section, and the heat insulation sleeve at the bottom of the support section is inserted into the installation groove. Through the above improvements, the installation stability of the heat insulation column is enhanced, and the heat conduction between it and the top plate is effectively reduced, further optimizing the heat insulation effect between the upper and lower cavities.

[0010] Preferably, a first heat insulation pad is provided in the first heat insulation groove. Through the above improvements, the sealing and heat insulation effects are increased.

[0011] Preferably, the second heat insulation groove has a vertically arranged first insertion part and a horizontally arranged second insertion part. The top of the first side plate and the bottom of the second side plate are inserted into the first insertion part, and the sides of the first top plate and the second bottom plate are inserted into the second insertion part. A second heat insulation pad is provided in the first insertion part and the second insertion part. Through the above improvements, the assembly stability between the multi-layer structure is significantly enhanced, and the heat transfer between different cooking areas is effectively suppressed, thereby improving the accuracy of the dual-cavity independent temperature control and the overall heat insulation performance of the machine.

[0012] Preferably, the mounting bracket is equipped with a first temperature detector and a second temperature detector, with the first temperature detector placed inside the first cooking cavity and the second temperature detector placed inside the second cooking cavity. Through the above improvements, independent real-time monitoring of the temperature of the upper and lower cooking cavities is achieved, providing a reliable basis for precise temperature control and further ensuring the effect of independent cooking in both zones and the quality of food processing.

[0013] Preferably, the side of the housing forms a first heat dissipation groove, and the bottom of the housing forms a second heat dissipation groove. Through the above improvements, the heat dissipation efficiency of the whole machine during operation is effectively enhanced, heat accumulation is avoided, and the stability and safety of the equipment during long-term operation are improved.

[0014] Preferably, the outer periphery of the housing is provided with a first control panel for controlling the temperature of the first cooking chamber and a second control panel for controlling the temperature of the second cooking chamber. With the above improvements, the user can simultaneously set and adjust the temperature of the upper and lower cooking zones independently and precisely, which significantly improves the convenience of operation and the flexibility of independent cooking in the two zones.

[0015] Preferably, the side of the housing is also provided with an air inlet seat that connects to the mounting bracket. The air inlet seat is arranged adjacent to the first heat dissipation groove, and the air inlet seat extends outward with a baffle plate. Through the above improvements, external airflow is effectively guided into the housing and the internal air duct circulation is optimized. At the same time, the baffle plate can reduce hot air backflow and external foreign object intrusion, thereby improving the overall operating stability of the machine.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects: By setting up independent first and second cooking sections within the housing and equipping them with heating components that supply hot air to both, a zoned cooking function is achieved. The heating components include a mounting bracket, and a heating unit and an exhaust unit mounted on the bracket. The mounting bracket is designed with a first heat-insulating groove, into which the first and second cooking sections are respectively inserted for lateral fixation. A heat-insulating seat is provided between the first and second cooking sections, and a second heat-insulating groove is formed on the heat-insulating seat. The top of the first cooking section and the bottom of the second cooking section are both embedded in the groove, achieving connection and effective heat insulation between the two. This structure can significantly reduce heat transfer during the cooking process, avoid mutual interference, and ensure stable and reliable cooking results. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0020] like Figure 1-7 As shown, a double-layer air fryer with independent temperature control includes a shell 1, a first cooking section 2 and a second cooking section 3 disposed inside the shell 1, and a heating component 4 for supplying hot air to the first cooking section 2 and the second cooking section 3. The first cooking section 2 and the second cooking section 3 respectively form a first cooking cavity 5 and a second cooking cavity 6. The heating component 4 includes a mounting bracket 1.1, a heating unit 1.2 disposed on the mounting bracket 1.1, and a ventilation unit 1.3.

[0021] Specifically, the mounting bracket 1.1 has a first heat insulation groove 1.4, the first cooking part 2 and the second cooking part 3 are inserted into the first heat insulation groove 1.4, a heat insulation seat 1.5 is provided between the first cooking part 2 and the second cooking part 3, a second heat insulation groove 1.6 is formed on the heat insulation seat 1.5, and the top of the first cooking part 2 and the bottom of the second cooking part 3 are respectively inserted into the second heat insulation groove 1.6.

[0022] Lateral fixation is achieved by inserting the first cooking section 2 and the second cooking section 3 into the first heat insulation groove 1.4, respectively. The mounting bracket 1.1 is made of a high-temperature resistant material that does not conduct heat (e.g., PEEK), effectively preventing heat conduction between the first cooking section 2 and the second cooking section 3 through the mounting bracket 1.1. A heat insulation seat 1.5 is provided between the first cooking section 2 and the second cooking section 3. The heat insulation seat 1.5 is also made of a high-temperature resistant material that does not conduct heat. A second heat insulation groove 1.6 is formed on the heat insulation seat 1.5. The top of the first cooking section 2 and the bottom of the second cooking section 3 are embedded in the groove, achieving connection and effective heat insulation between the two. This structure can significantly reduce heat transfer during the cooking process, avoid mutual interference, and ensure stable and reliable cooking results. At the same time, the heat insulation seat 1.5 ensures the reliability of the installation of the first cooking section 2 and the second cooking section 3.

[0023] like Figures 4 to 7 As shown, to further explain the specific structure of the first cooking section 2 and the second cooking section 3, the first cooking section 2 includes a first side plate 2.1, a first bottom plate 2.2, and a first top plate 2.3.

The second cooking section 3 includes a second side plate 2.4, a second bottom plate 2.5, and a second top plate 2.6. The second side plate 2.4, the second bottom plate 2.5, and the second top plate 2.6 enclose a second cooking cavity 6. The first cooking section 2 and the second cooking section 3 are independently assembled, which significantly improves the heat insulation performance and temperature independence of the double-layer fryer. This meets the user's need to cook different ingredients at the same time while avoiding temperature conduction between the first cooking section 2 and the second cooking section 3, which would affect the cooking effect.

[0024] In addition, the sides of the first cooking section 2 and the second cooking section 3 are both inserted into the mounting bracket 1.1. The mounting bracket 1.1 is equipped with two sets of heating units 1.2 and exhaust units 1.3, which respectively supply hot air to the first cooking section 2 and the second cooking section 3. The exhaust unit 1.3 introduces air from the outside, and after passing through the heating unit 1.2, it enters the first cooking cavity 5 and the second cooking cavity 6, realizing the zoned cooking function and avoiding heat conduction between multiple cooking cavities when they work at the same time.

[0025] like Figures 4 to 7As shown, a further explanation of the embodiment of the mounting bracket 1.1 is provided. A support positioning plate 3.1 extends from the mounting bracket 1.1. A plurality of heat insulation columns 3.2 are inserted into the support positioning plate 3.1, and the two ends of the heat insulation columns 3.2 respectively abut against the top of the first base plate 2.2 and the bottom of the second base plate 2.5. The support positioning plate 3.1 is inserted into the heat insulation seat 1.5. Since the first cooking part 2 and the second cooking part 3 are independently spliced ​​together, the structural strength can be improved by supporting the second cooking part 3 through the heat insulation columns 3.2.

[0026] In addition, the support positioning plate 3.1 is inserted into the heat insulation seat 1.5, which can further improve the stability of the heat insulation column 3.2 installation.

[0027] Furthermore, the first top plate 2.3 has an installation groove 3.3, and the heat insulation column 3.2 includes a support section 3.4 and heat insulation sleeves 3.5 disposed at both ends of the support section 3.4. The heat insulation sleeves 3.5 at the bottom of the support section 3.4 are inserted into the installation groove 3.3, which enhances the installation stability of the heat insulation column 3.2 and effectively reduces heat conduction between it and the top plate, further optimizing the heat insulation effect between the upper and lower cavities.

[0028] Preferably, a first heat insulation pad 4.1 is provided inside the first heat insulation groove 1.4, which increases the sealing and heat insulation effect.

[0029] like Figure 4 , Figure 5 As shown, as a further explanation of the embodiment of the heat insulation seat 1.5, the second heat insulation groove 1.6 has a vertically arranged first insertion part 4.2 and a horizontally arranged second insertion part 4.3. The top of the first side plate 2.1 and the bottom of the second side plate 2.4 are inserted into the first insertion part 4.2, and the sides of the first top plate 2.3 and the second bottom plate 2.5 are inserted into the second insertion part 4.3. A second heat insulation pad 4.8 is provided in the first insertion part 4.2 and the second insertion part 4.3, which significantly enhances the assembly stability between the multi-layer structure and effectively suppresses the heat transfer between different cooking areas, thereby improving the accuracy of the independent temperature control of the dual cavities and the overall heat insulation performance of the machine.

[0030] like Figure 1 , Figure 4 As shown, a further explanation of the temperature control of the first cooking section 2 and the second cooking section 3 is provided: a first temperature detector 4.4 and a second temperature detector 4.5 are inserted into the mounting bracket 1.1, with the first temperature detector 4.4 placed in the first cooking cavity 5 and the second temperature detector 4.5 placed in the second cooking cavity 6. This enables independent real-time monitoring of the temperature of the upper and lower cooking cavities, providing a reliable basis for precise temperature control and further ensuring the effect of independent cooking in both zones and the quality of food processing.

[0031] In addition, the outer periphery of the housing 1 is provided with a first control panel 5.1 for controlling the temperature of the first cooking chamber 5 and a second control panel 5.2 for controlling the temperature of the second cooking chamber 6. Users can simultaneously set and adjust the temperature of the upper and lower cooking zones independently and precisely, which significantly improves the convenience of operation and the flexibility of independent cooking in the two zones.

[0032] like Figure 2 , Figure 3 As shown, in some other embodiments, the side of the housing 1 forms a first heat dissipation groove 4.6, and the bottom of the housing 1 forms a second heat dissipation groove 4.7, which effectively enhances the heat dissipation efficiency of the whole machine during operation, avoids heat accumulation, and improves the stability and safety of the equipment during long-term operation.

[0033] Furthermore, the side of the housing 1 is also provided with an air inlet seat 5.3 that connects to the mounting bracket 1.1. The air inlet seat 5.3 is arranged adjacent to the first heat dissipation groove 4.6, and the air inlet seat 5.3 extends outward with a baffle plate 5.4, which effectively guides the external airflow into and optimizes the internal air duct circulation. At the same time, the baffle plate 5.4 can reduce hot air backflow and the intrusion of external foreign objects, thereby improving the overall operational stability of the machine.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
