Description

Technical Field

[0001] This utility model relates to the field of air fryer technology, specifically to an air fryer with a split fan assembly that is easy to clean. Background Technology

[0002] To address the issue of cleaning grease from the internal fan and heating components of existing air fryers, some solutions employ a detachable component design. These devices are widely used in home kitchens, allowing for deep cleaning by disassembling easily soiled parts to ensure food hygiene during cooking and prevent long-term grease buildup from causing odors or affecting device performance. Chinese patent CN202420522959 discloses an air fryer with a detachable heating component, comprising a body and a heating component. The body has a cooking cavity and a window communicating with the cooking cavity. The heating component is detachably disposed in the window for heating the cooking cavity. The heating component includes a heating tube, a heat spreader fan, and a fixing cover. The heat spreader fan and the cooling fan are connected to a motor via the same rotating shaft. The motor output shaft is connected to the rotating shaft via a clutch (upper clutch and lower clutch). Tracks are provided on both sides inside the body. The annular protrusion on the outer periphery of the heating component engages with the track. When disassembling, the heating component needs to be slid out through the track, and the motor needs to be disengaged from the clutch to clean the component.

[0003] However, the referenced documents and devices in existing similar technologies still have the following drawbacks in practical use: 1. The disassembly process is cumbersome, relying on the prior operation of the motor and clutch. The referenced document shows that the fan (heating fan, cooling fan) is integrated with the heating component, and the fan shaft is rigidly bound to the motor output shaft through the clutch. If the fan needs to be disassembled for cleaning, the inspection cover on top of the main body must be opened first, and the motor must be lifted upwards to disengage the clutch. This step requires the user to manually adjust the position of the motor component, which is a high operational threshold. Subsequently, the entire heating component, including the fan and heating tube, must be slid out along the track. The fan cannot be disassembled separately. The whole process requires step-by-step operation of the motor, clutch, and heating component, rather than directly disassembling the fan component, which contradicts the core requirement of "easy cleaning". Especially for ordinary household users, the operation complexity is significantly increased.

[0004] 2. The fan and heating element are forcibly integrated, and frequent disassembly and reassembly lead to wear and tear on the heating components. The referenced document fixes the fan and heating element together to the mounting cover, forming a "disassemble and reassemble" structure. However, in actual use, the fan, because it continuously participates in airflow circulation, accumulates oil stains on its surface much faster than the heating element, requiring more frequent cleaning. Frequent disassembly of the entire heating element causes the power connector at the end of the heating element to be repeatedly plugged and unplugged from the socket in the cooking cavity, resulting in wear and oxidation of the contact pieces, which in turn leads to problems such as poor circuit contact and reduced heating efficiency. At the same time, the heating element is fixed to the mounting cover by an L-shaped bracket. Repeated disassembly and reassembly can easily cause the bracket to deform or loosen, causing the heating element to shift position, disrupting the uniformity of heating in the cooking cavity, and shortening the lifespan of the heating element in the long run.

[0005] 3. The motor and fan drive structure are bound together, resulting in high maintenance costs and potential impact on transmission accuracy. In the referenced document, the motor is fixed in an independent mounting cavity, and its output shaft is directly connected to the fan rotation shaft via a clutch. If only cleaning or replacing the fan is required, the motor components still need to be used. During motor relocation, if the clutch is bumped or misaligned, it can cause abnormal noise and vibration when the fan rotates, or even cause wear on the fan blades due to asynchronous transmission. In addition, as a precision component, frequent disassembly and assembly of the motor can easily compromise its stability, increasing the probability of equipment failure and further increasing the user's maintenance difficulty and cost, failing to meet the actual demand for "low-cost, high-efficiency cleaning".

[0006] Therefore, this utility model proposes an air fryer with a split fan assembly that is easy to clean. Utility Model Content

[0007] The purpose of this invention is to provide an air fryer with a split fan assembly that is easy to clean, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an air fryer with a split fan assembly for easy cleaning, comprising an air fryer body and a heating module, wherein the upper part of the heating module is equipped with a downward blowing blade, the lower blade is mounted on a lower fan assembly, and the lower fan assembly can be completely detached from the air fryer body; the lower blade is non-contact magnetically driven to the power component of the air fryer.

[0009] Preferably, the downward output end of the power component is provided with an upper magnetic group, and the lower blade is provided with a lower magnetic group that is magnetically driven by the upper magnetic group.

[0010] Preferably, the upper and lower magnetic groups each contain an even number of vertically aligned magnetic blocks. The magnetic blocks are axially distributed along the same transmission axis. These blocks are arranged opposite each other with alternating magnetic poles. The blocks are evenly spaced within the same horizontal plane along the circumference of the transmission axis, and each block's magnetic pole is axially positioned. In the circumferential arrangement, the upper magnetic group's blocks are evenly distributed with alternating N and S poles, as are the lower magnetic group's blocks. The N-pole blocks of the upper magnetic group correspond one-to-one with the S-pole blocks of the lower magnetic group, and vice versa, achieving a state of alternating reverse magnetic poles.

[0011] Preferably, the power component includes a motor, the output shaft of which is mounted to the upper magnetic assembly. The motor drives the upper magnetic assembly to rotate through the output shaft, and then drives the lower blade to rotate through the magnetic force of the upper and lower magnetic assemblies.

[0012] Preferably, the lower fan assembly further includes a detachable housing for accommodating the lower blades, the lower blades being rotatably assembled in the lower receiving cavity of the detachable housing; the detachable housing is slidably assembled with the air fryer body, and the assembled detachable housing and the lower pot body form the working cavity of the air fryer; when the lower blades are driven to rotate, downward airflow forms a circulating hot airflow in the detachable housing and the working cavity of the air fryer.

[0013] Preferably, the outer side of the detachable housing is provided with a pull-out part for easy gripping, and the bottom of the detachable housing is provided with a positioning post. When the detachable housing is slid into the fryer body and assembled to a preset position, the positioning post abuts against the inner wall or limiting structure of the fryer body to realize the assembly and positioning of the lower fan assembly.

[0014] Preferably, the downward-facing output shaft of the motor is also equipped with an upward-blowing upper blade, which is located on the side of the output shaft closer to the motor and is arranged vertically opposite to the lower blade; the upper blade rotates synchronously with the output shaft.

[0015] Preferably, the lower receiving cavity is an annular enclosing structure, with its inner wall surrounding the lower blade in the circumferential and axial directions, so that the lower blade is enclosed by the lower receiving cavity.

[0016] Preferably, the surface of the disassembled housing is provided with an air inlet, which is inclined downwards; the side of the disassembled housing near the air inlet is provided with an independent upper air duct and a lower air duct, and the airflow entering through the air inlet is divided into two airflows by the guidance of the upper air duct and the lower air duct.

[0017] Preferably, the upper air duct is connected to the area where the upper blade is located, and the air outlet of the lower air duct is connected to the area where the lower blade is located.

[0018] Preferably, the detachable housing is made of food-grade high-temperature resistant engineering plastic.

[0019] Compared with the prior art, the beneficial effects of this utility model are: 1. Addressing the shortcomings of existing technologies where the fan and motor are rigidly bound by a clutch, requiring manual separation of the motor and transmission structure for disassembly, this utility model adopts an innovative design of non-contact magnetic transmission and a fully detachable fan assembly. The lower blades achieve magnetic coupling transmission through the lower magnetic group and the upper magnetic group on the power component, completely eliminating the traditional contact shaft system and clutch structure. When cleaning is required, the user does not need to disassemble the motor or adjust the clutch; simply hold the pull-out part of the lower fan assembly's detachable housing to horizontally pull the entire assembly, including the lower blades and lower magnetic group, out of the fryer body. During this process, the lower magnetic group moves away from the upper magnetic group as the detachable housing moves away, and the magnetic coupling is naturally released. The entire process requires no movement of the motor components, significantly reducing the operational threshold and truly achieving the convenience of "independent disassembly and cleaning of the fan assembly, and no disassembly or assembly of the motor throughout the process." This solves the core pain point of existing technologies where "disassembly and cleaning of the fan requires step-by-step operation of the motor and clutch, resulting in a cumbersome process."

[0020] 2. In existing technologies, the motor and fan shaft are directly connected via a clutch. Disassembling and assembling the fan can easily cause the motor to shift or the clutch to collide, leading to problems such as abnormal transmission noise and motor failure. This utility model's non-contact magnetic transmission fundamentally cuts off the physical connection between the motor and the lower fan assembly: the motor is fixed inside the fryer body and the lower blades are driven indirectly only through the magnetic force of the upper and lower magnetic groups. Even if the lower fan assembly is disassembled multiple times, the position and status of the motor remain unaffected, completely avoiding problems such as unstable fixation and decreased transmission accuracy caused by frequent disassembly and assembly. This design significantly reduces the maintenance difficulty and cost of the equipment, solving the shortcomings of existing technologies where "the motor and fan transmission are bound together, making maintenance easy and costly."

[0021] 3. In existing technologies, the fan and heating element are forcibly integrated, leading to repeated disassembly and reassembly of the heating element due to the high-frequency cleaning of the fan. This causes problems such as wear on the power connector and displacement of the heating element. This invention completely separates the lower fan assembly from the heating module: the lower blades are only assembled in the detachable lower fan assembly, while the heating module is fixed inside the fryer body. When cleaning, the user only needs to disassemble the lower fan assembly, and the heating module remains in place throughout the process. This completely avoids repeated plugging and unplugging of the heating element power connector and deformation and loosening of the heating element bracket. This "independent fan disassembly and cleaning, fixed heating module" structural design not only meets the requirements of high-frequency fan cleaning but also ensures the long-term stability of the heating module, effectively solving the defects of "shortened lifespan and damage to heating uniformity caused by frequent disassembly and reassembly of the heating element" in existing technologies.

[0022] 4. In existing technologies, the air intake and fan airflow of air fryers often conflict in direction, resulting in air pressure loss and low heat circulation efficiency. This utility model has a downward-sloping air intake on the surface of the disassembled shell, and an independent upper and lower air duct is designed inside the air intake. After the external air enters through the air intake, it is precisely divided into two airflows. One airflow flows through the upper air duct to dissipate heat from the motor and participates in the overall heat dissipation circulation of the fryer body. The other airflow flows through the lower air duct and forms a superposition with the downward airflow of the lower blades, which significantly improves the air pressure utilization rate. This airflow splitting and directional coordination design improves the problems of "large airflow collision loss and uneven heat circulation" in existing technologies, and improves the uniformity of hot air coverage and circulation efficiency in the working chamber.

[0023] 5. In the prior art, the airflow of the fan blades tends to diffuse in all directions, resulting in low efficiency of hot air utilization and easy splashing of oil stains onto non-removable and washable areas. The lower receiving cavity of this utility model adopts a ring-shaped wrapping structure. Its circumferential and axial inner walls can gather the airflow of the lower blades, ensuring that the hot air flows in a concentrated manner to the heating module and working cavity. At the same time, the ring-shaped cavity wall can effectively prevent oil stains from splashing directly onto the non-removable and washable areas of the fryer body, further reducing the cleaning burden. This structural design solves the defects of the prior art that "the fan airflow is dispersed, resulting in low thermal efficiency and easy contamination of non-removable and washable parts by oil stains", and achieves synergistic optimization of thermal efficiency and cleaning convenience.

[0026] 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.

[0027] It should be noted that the heating module 2 in this device only provides the function of hot air heating (heating the airflow to a preset temperature through the internal heating element), the lower blade 31 only provides the function of downward airflow guidance (pressing the airflow downward through blade rotation), the upper blade 54 only provides the function of upward airflow guidance (transporting the airflow upward through blade rotation), and the upper magnetic group 51, the lower magnetic group 52 and the magnetic block 53 only provide the function of non-contact magnetic force transmission (achieving torque transmission through the interaction of magnetic poles with opposite poles attracting each other). The working principles (such as the electrothermal conversion principle of heating module 2, the airflow disturbance principle of the blades, and the magnetic coupling transmission principle of the magnetic group) and specific structures (such as the arrangement of heating elements in heating module 2 and the design of the curvature and number of lower blades 31) of the above components are all existing technologies. Given the universality of these structures, their specific principles will not be elaborated further.

[0028] like Figure 2 , Figure 5 as well as Figure 6 As shown, this utility model provides an embodiment of an air fryer with a split fan assembly that is easy to clean. It includes an air fryer body 1 and a heating module 2. The upper part of the heating module 2 is equipped with a downward blowing blade 31. The lower blade 31 is mounted on the lower fan assembly 3, and the lower fan assembly 3 can be completely detached from the air fryer body 1. The lower blade 31 is non-contact magnetically driven to the power component 4 of the air fryer.

[0029] It should be noted that, as Figure 5 and Figure 6 As shown, the downward output end of the power component 4 is provided with an upper magnetic group 51, and the lower blade 31 is provided with a lower magnetic group 52 that is magnetically driven by the upper magnetic group 51. like Figure 5 , Figure 6 as well as Figure 9 As shown, the upper magnetic group 51 and the lower magnetic group 52 each have an even number of magnetic blocks 53 vertically. The magnetic blocks 53 of the upper magnetic group 51 and the lower magnetic group 52 are evenly distributed along the same transmission axis. The magnetic blocks 53 evenly distributed on the upper magnetic group 51 or the lower magnetic group 52 are arranged opposite each other in an alternating manner with magnetic poles. The magnetic blocks 53 are evenly spaced in the same horizontal plane along the circumference of the transmission axis, and the magnetic poles of each magnetic block 53 are axially arranged. In the circumferential arrangement, the magnetic blocks 53 of the upper magnetic group 51 are evenly distributed in an alternating manner with N poles and S poles, and the magnetic blocks 53 of the lower magnetic group 52 are also evenly distributed in an alternating manner with N poles and S poles. The N pole magnetic blocks 53 of the upper magnetic group 51 correspond one-to-one with the S pole magnetic blocks 53 of the lower magnetic group 52, and the S pole magnetic blocks 53 of the upper magnetic group 51 correspond one-to-one with the N pole magnetic blocks 53 of the lower magnetic group 52, realizing a cooperative state of alternating magnetic poles.

[0030] like Figure 5 and Figure 6 As shown, the power component 4 includes a motor 41, the output shaft of which is mounted to the upper magnetic assembly 51. The motor 41 drives the upper magnetic assembly 51 to rotate through the output shaft, and then drives the lower blade 31 to rotate through the magnetic force of the upper magnetic assembly 51 and the lower magnetic assembly 52. ​​The lower fan assembly 3 also includes a disassembly housing 32 for accommodating the lower blade 31. The lower blade 31 is rotatably assembled in the lower receiving cavity 321 of the disassembly housing 32. The disassembly housing 32 is slidably assembled with the air fryer body 1. After assembly, the disassembly housing 32 and the lower pot body form the working cavity of the air fryer. When the lower blade 31 is driven to rotate, the downward blowing air forms a circulating hot airflow in the disassembly housing 32 and the working cavity of the air fryer.

[0031] like Figure 5 , Figures 6 to 8 As shown, the outer side of the disassembly housing 32 is provided with a pull-out part for easy gripping, and the bottom of the disassembly housing 32 is provided with a positioning post 33. When the disassembly housing 32 is slid into the fryer body 1 and assembled to the preset position, the positioning post 33 abuts against the inner wall or limiting structure of the fryer body 1 to realize the assembly and positioning of the lower fan assembly 3. The downward output shaft of the motor 41 is also equipped with an upward blowing upper blade 54. The upper blade 54 is located on the side of the output shaft close to the motor 41 and is arranged vertically opposite to the lower blade 31. The upper blade 54 rotates synchronously with the output shaft.

[0032] like Figure 2 , Figure 3 , Figure 6 as well as Figure 10As shown, the lower receiving cavity 321 is an annular enclosing structure, with its inner wall surrounding the lower blade 31 circumferentially and axially, so that the lower blade 31 is enclosed by the lower receiving cavity 321. An air inlet 322 is provided on the surface of the disassembled housing 32, and the air inlet 322 is inclined downward. The side of the disassembled housing 32 near the air inlet 322 is provided with an independent upper air duct 323 and a lower air duct 324. The airflow entering through the air inlet 322 is divided into two airflows by the guidance of the upper air duct 323 and the lower air duct 324.

[0033] It is worth noting that the upper air duct 323 is connected to the area where the upper blade 54 is located, the air outlet of the lower air duct 324 is connected to the area where the lower blade 31 is located, and the disassembled housing 32 is made of food-grade high-temperature resistant engineering plastic.

[0034] Specifically, when cleaning is required after cooking, users do not need to disassemble fixed parts such as the motor 41 as with traditional air fryers. They only need to hold the pull-out part designed on the outer side of the disassembly shell 32 and pull it out horizontally to start the disassembly process.

[0035] Specifically, the disassembled housing 32 moves smoothly outward along the fryer body 1, and the positioning post 33 at its bottom gradually detaches from the inner wall of the fryer body 1. At the same time, the lower magnetic group 52 moves away from the upper magnetic group 51 along with the disassembled housing 32, and the magnetic coupling relationship is naturally released, and the transmission connection between the lower blade 31 and the upper blade 54 stops.

[0036] The user continues to pull outwards to disassemble the housing 32 until it is completely detached from the fryer body 1. At this point, the disassembled housing 32, which encloses the lower blade 31, is completely removed. All components that come into direct contact with cooking oil, such as the lower blade 31, the annular inner wall of the lower receiving cavity 321, the downward-sloping air inlet 322, and the independent upper and lower air ducts 323 and 324, are fully exposed. The user can thoroughly wash or wipe these components, thus avoiding the cleaning dead spots caused by the forced integration of components such as the fan, heating module 2, and motor 41 in traditional air fryers. This significantly reduces the difficulty of cleaning and allows users to complete the deep cleaning of the equipment without spending too much time and effort.

[0037] When assembling after cleaning, the user only needs to align the disassembled housing 32 with the fryer body 1 and push it in smoothly: during the sliding process of the disassembled housing 32, the positioning post 33 at the bottom restricts the circumferential displacement of the disassembled housing 32, thereby ensuring that the upper magnetic group 51 and the lower magnetic group 52 can be precisely aligned along the same transmission axis. When the disassembled housing 32 is pushed into the preset position, the positioning post 33 and the limiting structure of the fryer body 1 are in close contact again. In this state, the magnetic blocks 53 of the upper magnetic group 51 and the lower magnetic group 52 re-form the N-pole to S-pole alternating relationship, the magnetic transmission function is immediately restored, and the lower blade 31 can rotate synchronously with the output shaft of the motor 41.

[0038] The entire assembly process does not require the user to manually calibrate the relative positions of the upper magnetic group 51 and the lower magnetic group 52. The mechanical positioning function of the positioning column 33 and the magnetic guiding function of the magnetic group itself form a dual guarantee, ensuring that the equipment can quickly and accurately return to the working state, allowing the user to start the next cooking operation immediately.

[0039] It is worth noting that when the fryer body 1 is in use, the output shaft of the motor 41 rotates, driving the upper magnetic group 51 to rotate synchronously. Through the alternating magnetic pole cooperation of "N pole to S pole, S pole to N pole" with the lower magnetic group 52, contactless torque transmission is achieved, thereby driving the lower blade 31 to rotate in the lower receiving cavity 321. This non-contact design not only avoids the risks of shaft wear and oil stain jamming in traditional contact transmission, but also structurally supports the overall detachability of the lower fan assembly 3, laying the transmission foundation for "easy cleaning".

[0040] At the same time, when the lower blade 31 and the upper blade 54 rotate, the external air enters through the downward-sloping air inlet 322 on the surface of the disassembled housing 32. It is naturally divided into two airflows by the upper air duct 323 and the lower air duct 324. One airflow is transported to the area where the upper blade 54 is located through the upper air duct 323. Under the upward blowing action of the upper blade 54, on the one hand, it dissipates heat from the motor 41 and other heat-generating components. On the other hand, this airflow also flows through the inner wall of the fryer body 1 and the circuit component area, carrying away the excess heat generated during the operation of the equipment, thereby achieving heat dissipation protection for the entire fryer body 1 and avoiding local overheating that could affect the lifespan of the circuit. Another airflow is directly guided to the area of ​​the lower blade 31 through the lower air duct 324. Since the air outlet direction of the lower air duct 324 is consistent with the downward air output direction of the lower blade 31, the two airflows form a superposition effect in the same direction, which effectively reduces the air pressure loss caused by the conflict of airflow directions in the traditional design, and improves the air pressure utilization rate of the lower blade 31. After the airflow passes through the heating module 2 and is quickly heated to the preset temperature, it enters the working chamber formed by the disassembled shell 32 and the lower pot body more efficiently to fully heat the food.

[0041] The annular lower receiving cavity 321 plays a role in "gathering and directional guiding" the airflow of the lower blade 31: its circumferential and axial inner wall structure can prevent the airflow blown out by the lower blade 31 from spreading to all sides, ensuring that the hot air flows to the heating module 2 and the working cavity in a concentrated manner, which significantly improves the utilization efficiency of hot air and the temperature uniformity of the cooking cavity. At the same time, the annular cavity wall can also effectively prevent oil stains from splashing directly to non-disassembly areas, further reducing the cleaning burden.

[0042] This multi-dimensional collaborative design of "transmission-airflow-structure" ultimately achieves a dual optimization of "cleaning convenience" and "cooking efficiency".
