Description

Technical Field

[0001] This invention relates to the field of cooking equipment technology, and more specifically to an air oven. Background Technology

[0002] An air fryer is a baking appliance that uses high-speed air circulation technology to cook food. Its main principle is to rapidly heat the air by passing it through a heating element, and then use a high-powered fan to create a rapid circulation of hot air inside the food basket. This results in a crispy surface on the food while locking in the moisture inside, achieving the same fragrant and crispy texture as ordinary fried foods. Furthermore, since the cooking process does not involve frying, the fat content is significantly lower, making it more suitable for the currently promoted healthy eating environment.

[0003] Current air vent ovens often feature a large interior cavity, coupled with a high-powered convection fan, to accommodate cooking larger quantities of food. However, when cooking smaller quantities, the large interior cavity and high-powered convection fan consume more electricity, impacting the user experience. Summary of the Invention

[0004] In view of this, the present invention provides an air oven to solve the problem of high power consumption in current air ovens when cooking smaller quantities of food due to their large inner cavity and high-power hot air device design.

[0005] This invention provides an air-conditioning oven, comprising: The shell has an internal cavity; A partition assembly is detachably disposed in the cavity, the partition assembly dividing the cavity into multiple inner liner sections; Multiple door components are provided at the opening of the cavity, and the multiple door components are provided one-to-one with the multiple inner liner; Multiple hot air generating components are disposed inside the housing and are respectively arranged corresponding to the multiple inner liner components, and the multiple hot air generating components can respectively heat the multiple inner liner components; The control unit is communicatively connected to each of the multiple hot air generating components, and the control unit is capable of controlling the hot air generating components to generate heat respectively.

[0006] Beneficial effects: The present invention provides an air oven with a removable partition assembly that divides the cavity into multiple inner chambers, and is equipped with door assemblies and hot air generating assemblies corresponding to each of the multiple inner chambers. When cooking a small amount of food, the control unit can control one hot air generating assembly to generate heat, and only one of the smaller inner chambers is used to cook the food, thus avoiding the energy waste caused by the air oven running at full power.

[0007] Furthermore, the partition assembly divides the cavity into multiple inner liner units, each equipped with a door assembly and a hot air generator assembly. Each inner liner can circulate independently, preventing cross-contamination of flavors and temperature interference between upper and lower layers of food, thus meeting the needs of differentiated cooking for different foods.

[0008] In one alternative embodiment, the partition assembly extends laterally into the cavity, dividing the cavity longitudinally into at least two inner liner layers, and at least two door assemblies are sequentially arranged along the height direction of the housing; The partition assembly has a first mating part on its side and a second mating part on the inner wall of the cavity; when the partition assembly is inserted into the cavity, the first mating part and the second mating part engage with each other to install the partition assembly in the cavity.

[0009] Beneficial effects: By extending the partition assembly laterally into the cavity, two sets of inner pots are sequentially arranged along the height direction inside the cavity, thereby making full use of the longitudinal space of the shell and realizing the function of simultaneous cooking of two layers, improving cooking efficiency and space utilization; by correspondingly engaging the first and second mating parts, the partition assembly is stably fixed in the cavity.

[0010] In one optional embodiment, one of the first mating part and the second mating part is configured as a sliding groove, and the other of the first mating part and the second mating part is configured as a rib; when the partition assembly extends into the cavity, the rib slides relative to the sliding groove and engages accordingly, so as to install the partition assembly in the cavity.

[0011] Beneficial effects: The partition assembly and the cavity are connected by corresponding grooves and ribs, which makes the connection stable and easy to disassemble and assemble.

[0012] In one optional embodiment, the inner liner is provided with a frying drum, the rear side wall of the frying drum is provided with a return air hole, and both sides of the rear side wall of the frying drum are provided with air inlets; the hot air generating assembly is located at the rear of the frying drum. The air inlet is connected to the side air outlet of the hot air generating component, and the return air inlet is connected to the central return air channel of the hot air generating component.

[0013] Beneficial Effects: By placing the hot air generating component at the rear of the frying drum and connecting the air inlet to the side air outlet and the return air inlet to the central return air outlet, a circulating path is achieved where hot air enters from the rounded corners on both sides of the rear of the frying drum, passes through the food, and returns to the center. Compared to a structure with central air intake and side return air, this design, by distributing the air inlets at the rounded corners on both sides of the rear of the frying drum and concentrating the return air outlet at the center of the rear side wall, allows hot air to converge from all sides of the frying drum towards the center. This avoids the problem of excessively high central temperature and insufficient edge temperature caused by central air intake, resulting in a more uniform temperature distribution inside the frying drum and improved heating efficiency and cooking effect. It solves the problem of uneven temperature distribution inside the frying drum, which easily leads to overcooked food in the center and undercooked food at the edges, resulting in poor cooking effects.

[0014] In one optional embodiment, the inner liner is further provided with a flow guide hood, which is located at the top opening of the frying barrel. An air inlet channel is formed between the flow guide hood and the top of the frying barrel, and an air inlet is formed between the rear side wall of the frying barrel and the flow guide hood. The air inlet connects the air inlet channel and the upper air outlet channel of the hot air generating component.

[0015] Beneficial effects: By installing a deflector at the top opening of the frying drum, an air intake channel is formed between the deflector and the top of the frying drum, and an air inlet is formed between the rear side wall of the frying drum and the deflector, which connects to the air outlet channel at the top of the hot air generating component. This allows hot air from the top of the hot air generating component to be introduced into the air intake channel through the air inlet, and then enters the frying drum from the top opening downwards. This, combined with the side hot air entering from the rounded corner air inlets on both sides of the rear of the frying drum, achieves simultaneous air supply to the inside of the frying drum from multiple directions, including the top and sides. This allows the hot air to more comprehensively cover the surface of the food, improves the uniformity of temperature distribution inside the frying drum and the heating efficiency of the food, and enhances the cooking effect.

[0016] In one alternative embodiment, the flow deflector includes: First sidewall; The second sidewall is opposite to and spaced apart from the first sidewall, and the air inlet channel is formed between the first sidewall and the second sidewall; At least two first airflow guides are located between the first sidewall and the second sidewall. The at least two first airflow guides are arranged sequentially at intervals, and a central airflow guide channel is formed between two adjacent first airflow guides. The first sidewall of the airflow guide is spaced apart from the adjacent first airflow guides to form a first side airflow guide channel. The second sidewall of the airflow guide is spaced apart from the adjacent first airflow guides to form a second side airflow guide channel.

[0017] Beneficial effects: By setting at least two sequentially spaced first air guides in the air inlet channel, the air inlet channel is divided into a central air guide channel, a first side air guide channel, and a second side air guide channel. This allows hot air to enter through the air inlet and then be divided into multiple independent airflows that flow into the frying drum. This avoids the problem of localized overheating caused by concentrated airflow directly impacting the food surface. At the same time, the central air guide channel, the first side air guide channel, and the second side air guide channel allow hot air to enter evenly from different areas of the opening at the top of the frying drum. This, combined with the side hot air entering from the rounded corner air inlets on both sides of the rear of the frying drum, improves the uniformity of hot air distribution inside the frying drum and the consistency of food heating.

[0018] In one optional embodiment, the housing is provided with a first air inlet and an air outlet; At least two inner liner layers are sequentially arranged inside the shell along the height direction of the shell; a heat dissipation duct is provided between the inner liner and the shell, and the heat dissipation duct is connected to both the first air inlet and the air outlet; At least two layers of the door assembly are sequentially arranged at the opening of the cavity along the height direction of the housing, and the door assembly and the inner liner are arranged in a one-to-one correspondence; the door assembly is provided with a flow channel; The door assembly includes a conductive structure that connects the heat dissipation duct and the circulation channel; and two adjacent conductive structures are correspondingly arranged to connect two adjacent circulation channels.

[0019] Beneficial Effects: Because the door assembly includes a conductive structure that connects the heat dissipation duct and the circulation channel, and adjacent conductive structures are correspondingly arranged to connect adjacent circulation channels, the heat dissipation duct and multiple circulation channels are sequentially connected, forming a complete airflow circulation path. The cooling airflow not only removes heat from the heat dissipation duct but also continuously flows over the inner surface of the door assembly, carrying away heat from the door assembly itself. This not only prevents localized heat accumulation but also prevents heat transfer to the shell and door surface, improving the overall heat dissipation performance, extending service life, and enhancing the user experience. Simultaneously, the corresponding arrangement of adjacent conductive structures allows each circulation channel to connect and form an overall heat dissipation path, eliminating the need for separate ducts for each circulation channel, simplifying the overall airflow structure and reducing manufacturing and assembly costs. This solves the problems of insufficient door heat dissipation leading to excessive surface temperature rise in air-conditioning ovens, as well as the complex internal airflow structure, high manufacturing costs, and assembly difficulties.

[0020] In one optional implementation, the conducting structure includes: The first heat dissipation hole is located on the top surface of the door assembly and communicates with the flow channel; and the first heat dissipation hole is correspondingly provided with the upper conductive structure or communicates with the heat dissipation duct. The second heat dissipation hole is located on the bottom surface of the door assembly and is connected to the flow channel; and the second heat dissipation hole is correspondingly provided with the lower conductive structure or connected to the heat dissipation duct.

[0021] Beneficial effects: By setting a first heat dissipation hole on the top surface and a second heat dissipation hole on the bottom surface of each door component, and connecting the first heat dissipation hole to the upper conductive structure or heat dissipation duct, and the second heat dissipation hole to the lower conductive structure or heat dissipation duct, direct connection between the upper and lower flow channels is achieved, forming a longitudinally penetrating heat dissipation airflow path. This simplifies the air duct system and reduces the complexity of the overall air duct structure and manufacturing cost. At the same time, each door component can obtain a continuous and stable cooling airflow, effectively avoiding local overheating caused by uneven airflow between layers, and improving the overall heat dissipation efficiency and the uniformity of the surface temperature of the whole machine.

[0022] In one optional embodiment, the air oven further includes at least two sets of heat dissipation components, which are arranged sequentially along the height direction of the housing, and the heat dissipation components correspond one-to-one with the air outlet.

[0023] Beneficial effects: By sequentially arranging at least two sets of heat dissipation components along the height of the casing, and ensuring that each set of heat dissipation components corresponds to a specific air outlet, compared to a single air outlet or a single heat dissipation component, it is possible to actively extract hot air from different height areas of the casing, preventing hot air from concentrating at the top or stagnating at the bottom. At the same time, each set of heat dissipation components and its corresponding air outlet work independently to prevent airflow from interfering with or flowing between different areas, ensuring the exhaust efficiency and stability of the heat dissipation ducts in each layer, and improving the overall heat dissipation capacity of the entire unit.

[0024] In one optional embodiment, the housing further includes a motor cover and a rear cover, the air outlet is disposed on the motor cover, and the rear cover and the motor cover form an accommodating cavity; the heat dissipation assembly includes: A volute-shaped air duct is located in the motor cover and is connected to the corresponding air outlet. An air intake hole is provided on the motor cover, connecting the heat dissipation air duct and the volute air duct; a second air inlet is provided on the rear cover, and the second air inlet is connected to the air intake hole. A cooling fan is located inside the volute air duct; The drive mechanism is located inside the accommodating cavity and is connected to the cooling fan drive.

[0025] Beneficial Effects: By integrating the air outlet, volute air duct, and suction hole onto the motor cover, the number of parts is reduced, the internal layout of the housing is simplified, and space utilization is improved. The structure is also compact and easy to assemble and maintain. Simultaneously, by connecting the heat dissipation air duct and the volute air duct at both ends of the suction hole, and cooperating with the cooling fan located within the volute air duct, a complete airflow path is formed, from the heat dissipation air duct through the suction hole into the volute air duct, and then directed to the corresponding air outlet. This ensures smooth airflow and improves heat dissipation efficiency. The drive mechanism is housed within a cavity formed by the rear cover and the motor cover. This cavity provides a relatively closed or semi-closed protective environment for the drive mechanism, effectively preventing foreign objects or oil, moisture, or fine particles generated during cooking from directly entering the drive mechanism, thus improving the reliability and lifespan of the drive motor. By providing a second air inlet on the rear cover and directly connecting it to the suction hole, an additional air intake path is provided for the heat dissipation system. When the cooling fan is working, in addition to drawing in hot air from the cooling duct, it also simultaneously draws in cooler ambient air from outside the rear cover. The two types of air mix inside the volute duct through the intake vents before being exhausted through the exhaust vents. This reduces the temperature of the airflow entering the volute duct, preventing the cooling fan from being constantly in a hot air circulation loop and extending its lifespan. Furthermore, the second air intake acts as an auxiliary air source, ensuring sufficient airflow for the cooling fan even when the cooling duct experiences significant resistance due to dust accumulation, thus improving the overall cooling system's resilience and stability. Simultaneously, the second air intake, together with the first air intake, creates multiple air intake paths, helping to balance the internal air pressure of the entire system.

[0026] In one optional embodiment, each of the edges of two adjacent door components is provided with a sealing structure configured as a flexible elastic structure; when the two sealing structures come into contact, they can be squeezed against each other through elastic deformation so that the two sealing structures fit together.

[0027] Beneficial effects: When the two sealing structures come into contact, they can be squeezed together by elastic deformation, so that the two sealing structures fit together. This can play a sealing role between the two door components, preventing heat in the cavity from escaping from the gap between the two doors, avoiding heat loss inside the air oven, and ensuring the heating efficiency and heating effect of the air oven.

[0028] In one optional embodiment, the air oven further includes a door frame disposed on the housing, a rotating shaft rotatably connected between the side of the door frame and a plurality of door body assemblies, and the same side of the plurality of door body assemblies being rotatably connected to the door frame via the rotating shaft.

[0029] Beneficial effects: The rotating shaft is rotatably connected between the side of the door frame and the upper and lower door components, achieving a rotatable connection between the two doors and the door frame. Furthermore, since the upper and lower door components are rotatably connected on the same rotating shaft, the coaxiality of the two doors is good, resulting in a small relative height error during rotation. When the upper and lower door components close their cavities, the adjacent sealing structures can better fit together, thereby improving the sealing effect between the upper and lower door components.

[0030] In one optional embodiment, a rotary motor is provided in the bottom of the housing, the output end of the rotary motor extending into the cavity, and the air oven further includes a skewer rack driven through the output end of the rotary motor, the skewer rack comprising: The stringing rack is equipped with stringing holes; A grill skewer, detachably mounted on the skewer rack, includes a skewer needle and a skewer head, the skewer head having: The connecting part is inserted into the hole of the skewer to achieve horizontal positioning of the skewer; The first positioning part is formed by bending the through part, and the first positioning part has a limiting plane for contacting and cooperating with the upper surface of the hanging rack to realize the vertical lower limit of the grill stick; The second positioning part is located at the junction of the tag head and the tag needle, and the second positioning part has an abutting surface for abutting and limiting the position with the periphery of the hanging frame.

[0031] Beneficial effects: When the skewers are installed on the skewer rack, the through-hole on the skewer head passes through the skewer rack hole, which at least restricts the horizontal movement of the skewers. Under the action of gravity, the first positioning part on the skewer head makes contact with the upper surface of the skewer rack through the limiting plane, which reliably limits the lower position of the skewers. The abutting surface of the second positioning part on the skewer head abuts and limits the skewer with the periphery of the skewer rack. The through-hole and the second positioning part work together to further prevent the skewers from moving horizontally and rotating around the vertical axis. Compared with the unreliable lower and horizontal limiting methods in related technologies, which cannot limit rotation, the addition of the limiting plane and abutting surface changes the original point contact or line contact limiting method to surface contact, which effectively improves the connection between the skewers and the skewer rack, provides better positioning constraint, and the skewers are not easy to shift or shake after installation, thus meeting the usage requirements.

[0032] In one alternative implementation, the grill skewer further includes: A lifting portion is formed on the skewer head or installed on the top of the skewer head, and the lifting portion is connected between the first positioning portion and the second positioning portion.

[0033] Beneficial effects: The lifting section makes it easy for users to hold and lift the skewers, making operation convenient; moreover, the lifting section has a relatively low temperature, avoiding direct contact with the heated parts and preventing burns, thus improving safety. The lifting section is connected between the first and second positioning sections, resulting in better overall structural integrity and facilitating the creation of a hollow structure at the skewer tip for easier handling and better heat dissipation.

[0034] In one optional implementation, the hanging rack includes: The hanging tray has multiple stringing holes spaced circumferentially on its edge, and the tray surface is bent downward to form a folded edge, with the second positioning part abutting against the folded edge. The base is connected to the output end of the rotary motor for transmission. A support rod is used to support and install the hanging plate on the base, and the hanging plate and the base are respectively detachably disposed at both ends of the support rod.

[0035] Beneficial effects: The downward bending of the hanging tray's edge forms a folded edge, resulting in high structural strength. This folded edge acts as a contact point, engaging with the second positioning part to form a surface contact. The positioning contact surface is regular, ensuring stable and reliable contact and limiting. This ensures the folded edge effectively blocks and limits the sides of the skewers, preventing them from shifting or rotating. The folded edge is formed by integral bending of the hanging body, eliminating the need for additional limiting components. This results in a simple structure, convenient processing, and high overall strength. The hanging tray, support rod, and base are assembled in a detachable manner, allowing the skewer rack to be disassembled for storage. This significantly reduces storage space, making storage and transportation more convenient. It also facilitates individual cleaning and maintenance / replacement of the hanging tray, support rod, and base after disassembly.

[0036] In one optional embodiment, the housing is provided with a storage compartment, and the air oven further includes a retrieval clip disposed in the storage compartment; The retrieval clip includes: The grip portion is a shell structure with a bottom opening and a cavity. The top surface of the grip portion has a mounting groove, and the front end of the grip portion has a through hole. The mounting groove and the through hole are respectively connected to the cavity. A pivot shaft is provided in the cavity of the grip portion near the through hole. The buckle plate is provided with a clamping part and a pivoting part. The buckle plate is pivotally mounted on the pivot shaft, and at least the clamping part is provided outside the cavity of the gripping part through the through hole, forming a clamping opening between the clamping part and the gripping part. A rocker arm with a latch is fixedly connected to the latch plate to form a rotating arm that can rotate around the pivot axis. The locking assembly is provided with a locking tongue that can slide in the front-back direction for engaging with the locking latch. A trigger part is slidably disposed in the mounting groove along the vertical direction, and the trigger part is connected to the locking tongue in a driving connection. The rotating arm has a first position in a locked state and a second position in an unlocked state. When the rotating arm is in the first position, the latch engages and locks with the latch, restricting the swing of the rotating arm, locking the opening of the clamping opening, and the rocker block the open side of the gripping part. When force is applied to the trigger, the trigger causes the latch to disengage from the latch, and the rotating arm swings outward to the second position, so that the free end of the rocker moves away from the gripping part and the clamping opening opens. A first elastic element is installed between the buckle plate and the gripping part. When the rotating arm is in the first position, the first elastic element is in a compressed state.

[0037] Beneficial effects: The grabber, through the cooperation of a locking component, a trigger, and a rotating arm with a latch, allows for stable clamping of heavy objects without the need for continuous hand gripping force. This significantly reduces hand workload, making it particularly suitable for heavy-duty kitchen loading and unloading scenarios. Furthermore, the pivot point is located at the through-hole at the front of the grip, resulting in a more rational force distribution. Because the clamping force point is close to the grip, the lever arm is strategically positioned, allowing the load to be directly transferred to the pivot point when clamping heavy objects. This reduces grip deformation and stress concentration, improving overall structural strength and clamping stability, making it less prone to loosening or damage under heavy loads. The grabber has a simple and compact structure; it can be quickly unlocked by pressing the trigger, opening the grip. Operation is simple, and opening and closing are smooth.

[0038] In one alternative implementation, the locking tongue includes: The transmission part has a transmission through hole and a first inclined surface. The first inclined surface is adjacent to the front side of the transmission through hole and slopes downward toward the bottom of the transmission through hole. The trigger part has a second inclined surface, which is in frictional engagement with the first inclined surface. The engaging portion includes a first engaging surface and a third inclined surface. The first engaging surface is located on the upper surface of the engaging portion, and the third inclined surface is inclined in a direction away from the transmission portion and intersects with the first engaging surface. The latch is provided with a fourth inclined surface and a second engaging surface, and the inclination direction of the fourth inclined surface is the same as the inclination direction of the third inclined surface.

[0039] Beneficial effects: The second inclined surface of the trigger and the first inclined surface of the latch engage with each other. When the trigger is pressed, the second inclined surface squeezes the first inclined surface, smoothly converting the vertical force into the horizontal sliding thrust of the latch. The transmission is smooth, the structure is simple, and it is not easy to jam. The latch engagement part and the latch adopt the same inclined surface and the mutual engagement surface structure. When locked, the engagement surface is in close contact and the limit is reliable. During the unlocking and locking process, the inclined surface can play a guiding role. During the upward movement of the latch, the fourth inclined surface squeezes and pushes the latch forward a certain distance. When the two inclined surfaces reach the edge, the latch retracts under the action of the second elastic element, so that the first engagement surface of the latch and the second engagement surface of the latch are locked. The two inclined surfaces can guide the components to be smoothly aligned, reduce the biting resistance, and make the locking and unlocking actions smoother. The overall fit accuracy and operation stability are greatly improved. Attached Figure Description

[0048] According to an embodiment of the present invention, an air-conditioning oven is provided, such as... Figures 1-4 As shown, it includes: housing 1, partition assembly 102, door assembly 4, hot air generating assembly 20, and control unit.

[0049] The housing 1 has a cavity 101 inside; a partition assembly 102 is detachably disposed in the cavity 101, and the partition assembly 102 divides the cavity 101 into multiple inner liner 2; multiple door assemblies 4 are disposed at the opening of the cavity 101, and the multiple door assemblies 4 are arranged one-to-one with the multiple inner liner 2; multiple hot air generating assemblies 20 are disposed inside the housing 1 and are respectively arranged with the multiple inner liner 2, and the multiple hot air generating assemblies 20 can heat the multiple inner liner 2 respectively; the control unit is communicatively connected to the multiple hot air generating assemblies 20 respectively, and the control unit can control the hot air generating assemblies 20 to generate heat respectively.

[0050] In the above embodiment, a detachable partition assembly 102 is provided to divide the cavity 101 into multiple inner cavities 2, and a door assembly 4 and a hot air generating assembly 20 corresponding to each of the multiple inner cavities 2 are provided. When a small amount of food needs to be cooked, the control unit can control one hot air generating assembly 20 to generate heat, and only one of the smaller inner cavities 2 is used to cook the food, thus avoiding the energy waste caused by the air oven running at full power.

[0051] Furthermore, the partition assembly 102 divides the cavity 101 into multiple inner liner 2, each equipped with a door assembly 4 and a hot air generating assembly 20. The inner liners can circulate independently, avoiding cross-contamination of flavors and temperature interference between the upper and lower layers of food, and meeting the needs of differentiated cooking for different foods.

[0052] Specifically, when there is a large amount of food to be cooked, the user can remove the partition assembly 102 from the cavity 101, and the entire cavity 101 inside the shell 1 can then serve as a single large inner pot to meet the cooking needs of a large amount of food. When there is a small amount of food to be cooked or when the user does not want the food to have mixed flavors, the user can install the partition assembly 102 into the cavity 101, and the cavity 101 inside the shell 1 will be divided into multiple inner pots 2. With the door assembly 4 and hot air generator assembly 20 corresponding to each of the multiple inner pots 2, a small amount of food can be cooked using one set of inner pots 2, door assembly 4 and hot air generator assembly 20, or multiple sets of inner pots 2, door assembly 4 and hot air generator assembly 20 can be used to cook simultaneously while avoiding the mixing of flavors.

[0053] Furthermore, this embodiment does not limit the number of partition components 102, as long as the number of door components 4 and hot air generating components 20 corresponds one-to-one with the number of multiple inner liner 2 when the partition components 102 divide the inner liner 2.

[0054] In some embodiments, the partition assembly 102 extends laterally into the cavity 101, dividing the cavity 101 longitudinally into at least two inner liner 2 layers, and at least two door assemblies 4 are arranged sequentially along the height direction of the housing 1; the side of the partition assembly 102 is provided with a first mating part, and the inner wall of the cavity 101 is provided with a second mating part; when the partition assembly 102 extends into the cavity 101, the first mating part and the second mating part are engaged accordingly to install the partition assembly 102 in the cavity 101.

[0055] In the above embodiment, the partition assembly 102 extends laterally into the cavity 101, and two sets of inner pots 2 are arranged sequentially along the height direction inside the cavity 101, thereby making full use of the longitudinal space of the shell 1, realizing the function of simultaneous cooking of two layers, improving cooking efficiency and space utilization; the partition assembly 102 is stably fixed in the cavity 101 by correspondingly engaging the first and second mating parts.

[0056] Specifically, the first mating part provided on the side of the partition assembly 102 can be configured as a groove, a supporting boss, or other structures; the second mating part provided on the inner wall of the cavity 101 can be configured as a rib, an overlapping plate, or other structures.

[0057] In some embodiments, one of the first mating part and the second mating part is configured as a groove 1021, and the other of the first mating part and the second mating part is configured as a rib 1011; when the partition assembly 102 extends into the cavity 101, the rib 1011 slides relative to the groove 1021 and engages accordingly, so as to install the partition assembly 102 in the cavity 101.

[0058] In the above embodiments, the partition assembly 102 and the cavity 101 are connected by a sliding groove 1021 and a rib 1011, which makes the connection stable and easy to assemble and disassemble.

[0059] Specifically, in this embodiment, the first mating part on the side of the partition assembly 102 is configured as a sliding groove 1021, and the second mating part on the inner wall of the cavity 101 is configured as a protruding rib 1011. When the partition assembly 102 is installed into the cavity 101, the user pushes the partition assembly 102 into the cavity 101, and the protruding rib 1011 slides inward along the sliding groove 1021 and engages accordingly; when the partition assembly 102 is removed from the cavity 101, the user pulls the partition assembly 102 out of the cavity 101, and the protruding rib 1011 slides outward along the sliding groove 1021 and disengages.

[0060] In some embodiments, such as Figure 2 , Figures 5-8 As shown, the inner liner 2 is equipped with a frying drum 21. The rear side wall 2101 of the frying drum 21 is provided with a return air hole 2102, and both sides of the rear side wall 2101 of the frying drum 21 are provided with air inlets 2104. The hot air generating assembly 20 is located behind the frying drum 21. The air inlets 2104 are connected to the side air outlet channel of the hot air generating assembly 20, and the return air hole 2102 is connected to the central return air channel of the hot air generating assembly 20.

[0061] In the above embodiment, by placing the hot air generating component 20 at the rear of the frying bucket 21, and connecting the air inlet 2104 to the side air outlet and the return air inlet 2102 to the central return air outlet, a circulation path is achieved where hot air enters from the rounded corner structures 2103 on both sides of the rear of the frying bucket 21, passes through the food, and then returns from the center. Compared with the structure of central air intake and side air return, by dispersing the air inlets at the rounded corner structures 2103 on both sides of the rear of the frying bucket 21 and concentrating the return air outlet at the center of the rear side wall 2101, hot air converges from all sides of the frying bucket 21 towards the center. This avoids the problem of excessively high central temperature and insufficient edge temperature caused by central air intake, thus making the internal temperature distribution of the frying bucket 21 more uniform and improving the heating efficiency and cooking effect of the food. This solves the problem of uneven internal temperature distribution of the frying bucket 21, which easily leads to overcooked food in the middle and undercooked food at the edges, resulting in poor cooking effect.

[0062] Specifically, the rear sidewall 2101 of the frying drum 21 has multiple return air holes 2102 arranged in a mesh pattern. Both sides of the rear sidewall 2101 of the frying drum 21 have rounded corner structures 2103, and air inlets 2104 are located on the rounded corner structures 2103. The air inlets 2104 are elongated holes extending along the height direction of the frying drum 21.

[0063] In one optional embodiment, the inner liner 2 is further provided with a flow guide 22, which is located at the top opening of the frying barrel 21. An air inlet channel 2201 is formed between the flow guide 22 and the top of the frying barrel 21. An air inlet is formed between the rear side wall 2101 of the frying barrel 21 and the flow guide 22. The air inlet is connected to the air inlet channel 2201 and the upper air outlet channel of the hot air generating component 20.

[0064] In the above embodiment, by setting a guide hood 22 at the top opening of the frying bucket 21, an air inlet channel 2201 is formed between the guide hood 22 and the top of the frying bucket 21, and an air inlet communicating with the upper air outlet channel of the hot air generating component 20 is formed between the rear side wall 2101 of the frying bucket 21 and the guide hood 22. Thus, the hot air from the upper part of the hot air generating component 20 is introduced into the air inlet channel 2201 through the air inlet, and then enters the interior of the frying bucket 21 from the top opening of the frying bucket 21. This, combined with the side hot air entering from the air inlet holes 2104 of the rounded corner structures 2103 on both sides of the rear of the frying bucket 21, realizes the simultaneous supply of air to the interior of the frying bucket 21 from multiple directions, including the top and sides. This allows the hot air to more comprehensively cover the surface of the food, improves the uniformity of the temperature distribution inside the frying bucket 21 and the heating efficiency of the food, and enhances the cooking effect.

[0065] Specifically, the deflector 22 can be disposed at the bottom of the baffle assembly 102 for easy assembly.

[0066] In one alternative embodiment, the flow deflector 22 includes: a first sidewall 2202, a second sidewall 2203, and a first flow guide portion 2204.

[0067] The second sidewall 2203 is opposite to and spaced apart from the first sidewall 2202, and an air inlet channel 2201 is formed between the first sidewall 2202 and the second sidewall 2203; at least two first guide sections 2204 are located between the first sidewall 2202 and the second sidewall 2203, and the at least two first guide sections 2204 are arranged in sequence at intervals, and a central air guide channel 2205 is formed between two adjacent first guide sections 2204; the first sidewall 2202 of the air guide hood 22 is spaced apart from the adjacent first guide section 2204 to form a first side air guide channel 2206; the second sidewall 2203 of the air guide hood 22 is spaced apart from the adjacent first guide section 2204 to form a second side air guide channel 2207.

[0068] In the above embodiment, by providing at least two sequentially spaced first guide sections 2204 in the air inlet channel 2201, the air inlet channel 2201 is divided into a central guide channel 2205, a first side guide channel 2206, and a second side guide channel 2207. This allows hot air to enter through the air inlet and then be divided into multiple independent airflows that flow into the frying bucket 21. This avoids the problem of local overheating caused by concentrated airflow directly impacting the food surface. At the same time, the central guide channel 2205, the first side guide channel 2206, and the second side guide channel 2207 allow hot air to enter evenly from different areas of the top opening of the frying bucket 21. This, combined with the side hot air entering from the air inlets 2104 of the rounded corner structures 2103 on both sides of the rear of the frying bucket 21, improves the uniformity of hot air distribution inside the frying bucket 21 and the consistency of food heating.

[0069] It should be noted that the number of the first guide section 2204 is not limited in this embodiment, and there may be two, three or more first guide sections 2204.

[0070] Specifically, in this embodiment, the air guide shroud 22 is provided with two first air guide sections 2204. The two first air guide sections 2204 are spaced apart along the width direction of the air guide shroud 22 to form a central air guide channel 2205. The first air guide section 2204 on the left side is spaced apart from the first side wall 2202 of the air guide shroud 22 to form a first side air guide channel 2206. The first air guide section 2204 on the right side is spaced apart from the second side wall 2203 of the air guide shroud 22 to form a second side air guide channel 2207.

[0071] Furthermore, the air deflector 22 is provided with three or more first air deflectors 2204, and the three or more first air deflectors 2204 are spaced apart along the width direction of the air deflector 22 to form two or more central air deflector channels 2205. The first sidewall 2202 of the air deflector 22 is spaced apart from the adjacent first air deflector 2204 to form a first side air deflector channel 2206, and the second sidewall 2203 of the air deflector 22 is spaced apart from the adjacent first air deflector 2204 to form a second side air deflector channel 2207.

[0072] In some embodiments, the length of the central air guide channel 2205 is greater than the length of the first side air guide channel 2206 and greater than the length of the second side air guide channel 2207.

[0073] In the above embodiment, by setting the length of the central air guide channel 2205 to be greater than the length of the first side air guide channel 2206 and greater than the length of the second side air guide channel 2207, more hot air can flow through the central air guide channel 2205 to the central area of ​​the frying bucket 21, thereby providing focused air supply to the central part of the frying bucket 21, compensating for the deficiency of relatively insufficient air volume in the central area when the side air intake is used, making the hot air distribution inside the frying bucket 21 more balanced from the center to the edge, and further improving the uniformity of food heating and cooking effect.

[0074] In some embodiments, the length of the first side air guide channel 2206 is greater than the length of the second side air guide channel 2207; or the length of the second side air guide channel 2207 is greater than the length of the first side air guide channel 2206.

[0075] In the above embodiment, by setting the central air guide channel 2205, the first side air guide channel 2206 and the second side air guide channel 2207 to have different lengths, hot air enters the interior of the frying bucket 21 from different areas of the top opening of the frying bucket 21, thereby enabling the hot air to cover the interior space of the frying bucket 21 in sections, improving the uniformity of hot air entering the frying bucket 21 and the evenness of food heating.

[0076] In some embodiments, the air deflector 22 further includes a first guide slope 2208, which is located on the side of the central air deflector 2205 away from the hot air generating assembly 20 and extends obliquely from the top wall of the air deflector 22 toward the top opening of the frying barrel 21.

[0077] In the above embodiment, by providing a first guide slope 2208 on the top wall of the air guide hood 22 and positioning the first guide slope 2208 on the side of the central air guide channel 2205 away from the hot air generating component 20, and extending obliquely toward the top opening of the frying barrel 21, the hot air flowing out of the central air guide channel 2205 is changed from a horizontal flow to a downward flow direction toward the inside of the frying barrel 21, so that the hot air can be guided to the central area inside the frying barrel 21, avoiding the problem of uneven heating caused by the hot air circulating only in the upper layer of the frying barrel 21.

[0078] Preferably, the first guide slope 2208 and the top wall of the flow guide 22 have an arc transition.

[0079] In some embodiments, the air deflector 22 further includes a second guide slope 2209, which is located on the side of the first side air deflector 2206 away from the hot air generating assembly 20, and extends obliquely from the top wall of the air deflector 22 toward the top opening of the frying barrel 21.

[0080] In the above embodiment, by providing a second guide slope 2209 on the top wall of the air guide hood 22 and positioning the second guide slope 2209 on the side of the first side air guide channel 2206 away from the hot air generating component 20 and extending obliquely toward the top opening of the frying barrel 21, the hot air flowing out of the first side air guide channel 2206 is changed from a horizontal flow to a downward flow direction toward the inside of the frying barrel 21, so that the hot air can be guided to the left side area inside the frying barrel 21, avoiding the problem of uneven heating caused by the hot air circulating only in the upper layer of the frying barrel 21.

[0081] Preferably, the second guide slope 2209 and the top wall of the flow guide 22 have an arc transition.

[0082] In some embodiments, the air deflector 22 further includes a third guide slope 2210, which is located on the side of the second side air guide channel 2207 away from the hot air generating assembly 20 and extends obliquely from the top wall of the air deflector 22 toward the top opening of the frying barrel 21.

[0083] In the above embodiment, by providing a third guide slope 2210 on the top wall of the air guide hood 22, and positioning the third guide slope 2210 on the side of the second side air guide channel 2207 away from the hot air generating component 20, and extending obliquely toward the top opening of the frying bucket 21, the hot air flowing out of the second side air guide channel 2207 is changed from a horizontal flow to a downward oblique flow toward the inside of the frying bucket 21. This allows the hot air to be guided to the right side area inside the frying bucket 21, complementing the hot air guided by the first side air guide channel 2206 through the second guide slope 2209 to the left side area inside the frying bucket 21, and the hot air guided by the central air guide channel 2205 through the first guide slope 2208 to the central area inside the frying bucket 21. This improves the uniformity of the hot air distribution inside the frying bucket 21 and the consistency of food heating.

[0084] Preferably, the third guide slope 2210 and the top wall of the flow guide 22 have an arc transition.

[0085] In some embodiments, the air guide 22 further includes a second air guide portion 2211, which is located above the hot air generating assembly 20 and connected to the air guide 22. The second air guide portion 2211 is correspondingly disposed to the first air guide portion 2204.

[0086] In the above embodiment, by providing a second guide section 2211 on the guide shroud 22 above the hot air generating assembly 20, and by providing the second guide section 2211 in correspondence with the first guide section 2204, the hot air blown upward by the hot air generating assembly 20 is pre-distributed and guided, so that the hot air can accurately flow into the central air guide channel 2205, the first side air guide channel 2206 and the second side air guide channel 2207 formed by the first guide section 2204, thereby avoiding the problem of hot air spreading disorderly or concentrating on a certain area at the inlet of the air inlet channel 2201, and improving the uniformity of hot air distribution and air intake efficiency.

[0087] Specifically, the first guide section 2204 and the second guide section 2211 are configured in a one-to-one correspondence.

[0088] In some embodiments, the air deflector 22 further includes a third air deflector 2212, which is located on the side of the first air deflector 2204 away from the hot air generating assembly 20, and the third air deflector 2212 extends in the same direction as the first air deflector 2204.

[0089] In the above embodiment, by providing a third guide section 2212 in the air inlet channel 2201 and placing the third guide section 2212 on the side of the first guide section 2204 away from the hot air generating component 20, and extending the third guide section 2212 in the same direction as the first guide section 2204, a continuous separation structure is formed downstream of the first guide section 2204, which avoids the airflow from suddenly diffusing or interfering with each other at the ends of the middle air guide channel 2205, the first side air guide channel 2206 and the second side air guide channel 2207, thereby improving the stability of hot air distribution.

[0090] Specifically, in this embodiment, the length of the first side air guide channel 2206 is greater than the length of the second side air guide channel 2207, and a third guide section 2212 is provided between the second side air guide channel 2207 and the adjacent middle air guide channel 2205.

[0091] In another embodiment, the length of the second side air guide channel 2207 is greater than the length of the first side air guide channel 2206, and a third guide section 2212 is provided between the first side air guide channel 2206 and the adjacent middle air guide channel 2205.

[0092] In some embodiments, the hot air generating assembly 20 includes a heating element 201 and a centrifugal fan 202; the heating element 201 is disposed opposite to the return air hole 2102; the centrifugal fan 202 is disposed on the side of the heating element 201 away from the return air hole 2102.

[0093] In the above embodiment, by setting the heating element 201 opposite to the return air hole 2102, the airflow returning from the fryer 21 can flow directly through the heating element 201 and be quickly reheated, shortening the path of return air reheating and improving the heat circulation efficiency; at the same time, the centrifugal fan 202 is set on the side of the heating element 201 away from the return air hole 2102, so that the fan can stably draw in return air from the central return air channel and blow it out in the circumferential direction, forming a smooth axial air intake and radial air outlet circulation, which improves the air outlet stability of the hot air generating component 20.

[0094] In one alternative implementation, such as Figures 9-17 As shown, the housing 1 is provided with a first air inlet 11 and an air outlet 12; at least two inner liner 2 are arranged sequentially along the height direction of the housing 1 inside the housing 1; a heat dissipation duct 3 is provided between the inner liner 2 and the housing 1, and the heat dissipation duct 3 is connected to both the first air inlet 11 and the air outlet 12; at least two door assemblies 4 are arranged sequentially along the height direction of the housing 1 at the opening of the cavity 101, and the door assemblies 4 are arranged one-to-one with the inner liner 2; a flow channel 41 is provided inside the door assembly 4; wherein, the door assembly 4 includes a connecting structure 42, the connecting structure 42 connects the heat dissipation duct 3 and the flow channel 41; and two adjacent connecting structures 42 are arranged correspondingly to connect two adjacent flow channels 41.

[0095] In the above embodiment, since the door assembly 4 includes a conductive structure 42, which connects the heat dissipation duct 3 and the flow channel 41; and adjacent conductive structures 42 are correspondingly arranged to connect adjacent flow channels 41, so that the heat dissipation duct 3 and multiple flow channels 41 are sequentially connected to form a complete airflow circulation path. The cooling airflow can not only remove the heat in the heat dissipation duct 3, but also continuously flow over the inner side of the door assembly 4, removing the heat from the door assembly 4. This not only avoids local heat accumulation, but also prevents heat from being transferred to the shell 1 and the door surface, improving the heat dissipation performance of the entire machine surface, extending the service life and improving the user experience. At the same time, by utilizing the corresponding arrangement of adjacent conductive structures 42, each layer of flow channel 41 is interconnected to form an overall heat dissipation path, eliminating the need to set up an independent air duct for each layer of flow channel 41, simplifying the overall air duct structure and reducing manufacturing and assembly costs. This solves the problems of insufficient heat dissipation of the door leading to excessive surface temperature rise in air ovens, as well as the complex internal air duct structure, high manufacturing cost, and high assembly difficulty of the entire machine.

[0096] In one optional embodiment, the conductive structure 42 includes: a first heat dissipation hole 421 and a second heat dissipation hole 422.

[0097] The first heat dissipation hole 421 is located on the top surface of the door assembly 4 and is connected to the flow channel 41; the first heat dissipation hole 421 is correspondingly provided with the upper conductive structure 42 or is connected with the heat dissipation duct 3; the second heat dissipation hole 422 is located on the bottom surface of the door assembly 4 and is connected to the flow channel 41; the second heat dissipation hole 422 is correspondingly provided with the lower conductive structure 42 or is connected with the heat dissipation duct 3.

[0098] In the above embodiments, by providing a first heat dissipation hole 421 on the top surface and a second heat dissipation hole 422 on the bottom surface of each door assembly 4, and by connecting the first heat dissipation hole 421 to the upper conductive structure 42 or the heat dissipation duct 3, and connecting the second heat dissipation hole 422 to the lower conductive structure 42 or the heat dissipation duct 3, direct connection between the upper and lower flow channels 41 is achieved, forming a longitudinally penetrating heat dissipation airflow path. This simplifies the air duct system and reduces the complexity of the air duct structure and manufacturing cost of the entire machine. At the same time, each door assembly 4 can obtain a continuous and stable cooling airflow, effectively avoiding local overheating caused by uneven airflow between layers, and improving the overall heat dissipation efficiency and the uniformity of the surface temperature of the entire machine.

[0099] Specifically, this embodiment includes two inner liner layers 2 and two door assembly layers 4, with each door assembly layer 4 corresponding to one of the inner liner layers 2. That is, each inner liner layer 2 corresponds to one door assembly layer 4. Each door assembly layer 4 contains a flow channel 41.

[0100] The top surface of the upper door assembly 4 is provided with a first heat dissipation hole 421, which is connected to the top air duct 32 of the heat dissipation duct 3 to connect the upper circulation channel 41 and the top air duct 32; the bottom surface of the upper door assembly 4 is provided with a second heat dissipation hole 422, which is correspondingly provided with the conduction structure 42 of the lower door assembly 4 to connect the lower circulation channel 41 and the upper circulation channel 41.

[0101] The top surface of the lower door assembly 4 is provided with a first heat dissipation hole 421, which is correspondingly provided with a second heat dissipation hole 422 of the upper door assembly 4, and is used to connect the lower flow channel 41 with the upper flow channel 41; the bottom surface of the lower door assembly 4 is provided with a second heat dissipation hole 422, which is connected with the bottom air duct 31 of the heat dissipation air duct 3, and is used to connect the bottom air duct 31 with the lower flow channel 41.

[0102] The second heat dissipation hole 422 on the bottom surface of the upper door assembly 4 is correspondingly provided with the first heat dissipation hole 421 on the top surface of the lower door assembly 4, so that the flow channel 41 between the two adjacent door assemblies 4 is interconnected; at the same time, the first heat dissipation hole 421 on the top surface of the upper door assembly 4 is connected with the top air duct 32 of the heat dissipation air duct 3, and the second heat dissipation hole 422 on the bottom surface of the lower door assembly 4 is connected with the bottom air duct 31 of the heat dissipation air duct 3, thereby connecting the flow channel 41 of the entire door assembly 4 area with the heat dissipation air duct 3.

[0103] Furthermore, the door assembly 4 has three or more layers. The top surface of the middle layer door assembly 4 is provided with a first heat dissipation hole 421, which is correspondingly arranged with the conduction structure 42 of the upper layer door assembly 4 to connect the middle layer flow channel 41 with the upper layer flow channel 41. The bottom surface of the middle layer door assembly 4 is provided with a second heat dissipation hole 422, which is correspondingly arranged with the conduction structure 42 of the lower layer door assembly 4 to connect the middle layer flow channel 41 with the lower layer flow channel 41.

[0104] In one optional embodiment, the air oven further includes at least two sets of heat dissipation components 5, which are arranged sequentially along the height direction of the housing 1, and the heat dissipation components 5 correspond one-to-one with the air outlet 12.

[0105] In the above embodiment, by sequentially arranging at least two sets of heat dissipation components 5 along the height direction of the housing 1, and making each set of heat dissipation components 5 correspond one-to-one with the corresponding air outlet 12, compared with a single air outlet 12 or a single heat dissipation component 5, it is possible to actively extract hot air from different height areas of the housing 1, avoiding the accumulation of hot air at the top or stagnation at the bottom; at the same time, each set of heat dissipation components 5 and the corresponding air outlet 12 work independently to prevent airflow from interfering with or flowing between different areas, ensuring the exhaust efficiency and stability of each layer of heat dissipation air duct 3, and improving the overall heat dissipation capacity of the whole machine.

[0106] In some embodiments, the heat dissipation assembly 5 and the door assembly 4 are respectively disposed on opposite sides of the housing 1.

[0107] In the above embodiments, by setting the heat dissipation component 5 and the door component 4 on opposite sides of the housing 1, and concentrating the heat dissipation component 5 on the side away from the operating surface, spatial separation of the heat dissipation component 5 and the door component 4 is achieved. Compared with setting the cooling fan 53 on the top of the housing 1, this not only avoids mutual interference between the heat dissipation airflow and the door opening and closing area, preventing the heat dissipation efficiency from being affected when the door is opened, but also prevents the hot air discharged by the heat dissipation component 5 from directly spreading to the door opening and closing area, thus improving the safety of use; at the same time, it makes full use of the space of the opposite side walls of the housing 1, making the internal structure layout more compact and reasonable, and facilitating independent maintenance operations.

[0108] In one optional embodiment, the housing 1 further includes a motor cover 13 and a rear cover 14, with an air outlet 12 disposed on the motor cover 13, and the rear cover 14 and the motor cover 13 forming an accommodating cavity 15; the heat dissipation assembly 5 includes: a volute air duct 51, an air intake hole 52, a cooling fan 53, and a drive mechanism 54.

[0109] The volute air duct 51 is located on the motor cover 13 and is connected to the corresponding air outlet 12; the air intake 52 is located on the motor cover 13 and is connected to the heat dissipation air duct 3 and the volute air duct 51; the rear cover 14 is provided with a second air inlet 16, which is connected to the air intake 52; the cooling fan 53 is located inside the volute air duct 51; the drive mechanism 54 is located inside the accommodating cavity 15 and is connected to the cooling fan 53.

[0110] In the above embodiment, by integrating the air outlet 12, the volute air duct 51, and the suction hole 52 onto the motor cover 13, the number of parts is reduced, the internal layout of the housing 1 is simplified, and the space utilization rate is improved. The structure is also compact and easy to assemble and maintain. Simultaneously, the suction hole 52 connects the heat dissipation air duct 3 and the volute air duct 51 at both ends, and works in conjunction with the cooling fan 53 located within the volute air duct 51. This forms a complete heat dissipation airflow path from the heat dissipation air duct 3 through the suction hole 52 into the volute air duct 51, and then directed towards the corresponding air outlet 12, ensuring smooth airflow and improving heat dissipation efficiency. The drive mechanism 54 is housed by the rear cover 14 and the motor cover 13 forming a cavity 15. This cavity 15 provides a relatively closed or semi-closed protective environment for the drive mechanism 54, effectively preventing foreign objects or oil, moisture, or fine particles generated during cooking from directly entering the drive mechanism 54, thus improving the reliability and service life of the drive motor. By providing a second air inlet 16 on the rear cover 14 and directly connecting it to the suction hole 52, an additional air intake path is provided for the heat dissipation system. When the cooling fan 53 is working, in addition to drawing hot air from the heat dissipation duct 3, it can also simultaneously draw in cooler ambient air from outside the rear cover 14. The two airs mix inside the volute duct 51 through the suction hole 52 before being discharged through the outlet 12, reducing the temperature of the airflow entering the volute duct 51 and preventing the cooling fan 53 from being in a hot air circulation for a long time, thus extending its service life. Furthermore, the second air inlet 16 can serve as an auxiliary air intake source, ensuring that the cooling fan 53 still has sufficient air intake when the heat dissipation duct 3 experiences significant resistance due to dust accumulation or other reasons, thus improving the fault tolerance and stability of the entire heat dissipation system. At the same time, the second air inlet 16 and the first air inlet 11 form a multi-path air intake, which helps to balance the internal air pressure of the entire machine.

[0111] Specifically, the drive mechanism 54 is a motor.

[0112] Furthermore, in this embodiment, the cooling fan 53 and the centrifugal fan 202 are set to be the same fan, that is, the fan can play a dual role.

[0113] In some embodiments, the housing 1 further includes a bottom cover 17, and a first air inlet 11 is disposed on the bottom cover 17; the heat dissipation duct 3 includes a bottom air duct 31, which is disposed between the bottom cover 17 and the lower inner liner 2, and is connected to the first air inlet 11, the air outlet 12 and the conductive structure 42.

[0114] In the above embodiment, by setting the first air inlet 11 on the bottom cover 17 and setting the bottom air duct 31 between the bottom cover 17 and the lower inner liner 2, the bottom space of the shell 1 is effectively utilized, allowing external cooling gas to directly enter the heat dissipation air duct 3 from the bottom, forming a bottom-up heat dissipation airflow path, which conforms to the law of hot air rising naturally and enhances the heat dissipation effect. At the same time, the bottom air duct 31 is connected to the first air inlet 11, the air outlet 12 and the conduction structure 42, realizing synchronous air supply to the heat dissipation component 5 and the circulation channel 41, simplifying the air duct path of the whole machine and the number of openings in the shell 1, and reducing manufacturing costs and assembly difficulty.

[0115] Specifically, a gap is provided between the bottom cover 17 and the lower inner liner to form a bottom air duct 31.

[0116] Specifically, the first air inlet 11 is located on the bottom surface of the bottom cover 17 and is connected to the bottom air duct 31; external cooling gas flows through the first air inlet 11 and the guiding structure 42, and then through the bottom air duct 31 and the flow channel 41.

[0117] Specifically, the suction hole 52 is connected to the bottom air duct 31 and is used to draw the gas in the bottom air duct 31 into the volute air duct 51, and then discharge it from the air outlet 12.

[0118] In some embodiments, the housing 1 further includes a top cover 18; the heat dissipation duct 3 further includes a top duct 32, which is disposed between the top cover 18 and the upper inner liner 2, and is connected to the air outlet 12 and the conductive structure 42.

[0119] In the above embodiment, by setting the space between the top cover 18 and the upper inner liner 2 as the top air duct 32, and connecting the top air duct 32 to the air intake hole 52 and the guiding structure 42 respectively, the top space of the shell 1 is effectively utilized, forming a symmetrical heat dissipation layout with the bottom air duct 31. This allows the heat dissipation airflow to enter the top air duct 32 through the guiding structure 42 and then flow to the air outlet 12 through the air intake hole 52, achieving targeted heat dissipation of the upper area and avoiding heat accumulation at the top.

[0120] Specifically, a gap is provided between the top cover 18 and the upper inner liner to form a top air duct 32.

[0121] Specifically, the top air duct 32 is connected to the conduction structure 42 and the air intake hole 52 of the upper door assembly 4. The gas in the flow channel 41 flows through the top air duct 32 and the volute air duct 51 in sequence, and then is discharged from the air outlet 12.

[0122] In some embodiments, a door frame 6 is also included, which is disposed at the opening of the housing 1, and the door assembly 4 is connected to the door frame 6. The door frame 6 includes a first mating hole 61 and a second mating hole 62. The first mating hole 61 is correspondingly disposed with the conduction structure 42 of the upper door assembly 4 and communicates with the top air duct 32. The second mating hole 62 is correspondingly disposed with the conduction structure 42 of the lower door assembly 4 and communicates with the bottom air duct 31.

[0123] In the above embodiment, by setting the door frame 6 at the opening of the housing 1 and serving as the connection base for the door assembly 4, and by setting a first mating hole 61 and a second mating hole 62 on the door frame 6 respectively corresponding to the upper and lower conductive structures 42, with the first mating hole 61 connecting to the top air duct 32 and the second mating hole 62 connecting to the bottom air duct 31, the door frame 6 can not only install and fix the door assembly 4, but also connect the heat dissipation air duct 3 and the guide channel, ensuring the smooth flow and continuity of heat dissipation airflow between the upper and lower layers, and avoiding heat dissipation interruption or heat accumulation in the door frame 6 area due to structural obstruction.

[0124] Specifically, the first mating hole 61 is aligned with the first heat dissipation hole 421 on the top of the upper door assembly 4 in the assembly direction.

[0125] Preferably, a sealing structure such as a sealing gasket is provided between the top of the upper door assembly 4 and the top of the door frame 6, so that the top air duct 32 and the corresponding flow channel 41 of the upper door assembly 4 are sealed and connected.

[0126] Specifically, the second mating hole 62 is aligned with the second heat dissipation hole 422 at the bottom of the lower door assembly 4 in the assembly direction.

[0127] Preferably, a sealing structure such as a sealing gasket is provided between the bottom of the lower door assembly 4 and the bottom of the door frame 6, so that the bottom air duct 31 and the corresponding flow channel 41 of the lower door assembly 4 are sealed and connected.

[0128] Preferably, a sealing structure such as a sealing gasket is provided between two adjacent door body components 4, so that the two adjacent flow channels 41 are sealed and connected.

[0129] In operation, external cooling gas enters the bottom air duct 31 through the first air inlet 11 and splits into two paths. One path passes through the second mating hole 62 and the second heat dissipation hole 422 at the bottom of the lower door assembly 4, entering the flow channel 41 corresponding to the lower door assembly 4, carrying away the heat of the flow channel 41 corresponding to the lower door assembly 4. Then, it passes through the first heat dissipation hole 421 at the top of the lower door assembly 4 and the second heat dissipation hole 422 at the bottom of the upper door assembly 4, entering the flow channel 41 corresponding to the upper door assembly 4, carrying away the heat of the flow channel 41 corresponding to the upper door assembly 4. Then, it passes through the first heat dissipation hole 421 at the top of the upper door assembly 4 and the first mating hole 61, entering the top air duct 32, carrying away the heat of the top air duct 32. Finally, it enters the volute air duct 51 through the suction hole 52 and is discharged from the air outlet 12.

[0130] In one alternative implementation, such as Figures 18-21 As shown, each of the two adjacent door components 4 has a sealing structure 43 with a flexible elastic structure on its edge; when the two sealing structures 43 come into contact, they can be squeezed against each other through elastic deformation so that the two sealing structures 43 fit together.

[0131] In the above embodiment, when the two sealing structures 43 come into contact, they can be squeezed against each other through elastic deformation so that the two sealing structures 43 fit together. This can play a sealing role between the two door components 4, preventing the heat in the cavity 101 from escaping from the gap between the two doors, avoiding heat loss inside the air oven, and ensuring the heating efficiency and heating effect of the air oven.

[0132] Specifically, in this embodiment, the two-layer door assembly 4 adopts a vertical design with the top and bottom positioned vertically; as an alternative implementation, the door assembly 4 can also adopt a horizontal design with the left and right positioned horizontally. The sealing structure 43, which is set as a flexible elastic structure, can be a structure made of materials such as rubber, hydrogenated nitrile butadiene, or polyurethane.

[0133] In one alternative embodiment, the air oven further includes a door frame 6 disposed on the housing 1, and a rotating shaft 63 is rotatably connected between the side of the door frame 6 and a plurality of door body assemblies 4, with the same side of the plurality of door body assemblies 4 rotatably connected to the door frame 6 via the rotating shaft 63.

[0134] In the above embodiment, the rotating shaft 63 is rotatably connected between the side of the door frame 6 and the upper door assembly 4 and the lower door assembly 4, realizing the rotatable connection between the two doors and the door frame 6. Furthermore, the upper door assembly 4 and the lower door assembly 4 are rotatably connected to the same rotating shaft 63, resulting in good coaxiality between the two doors and a small relative height error during rotation. When the upper door assembly 4 and the lower door assembly 4 close the cavity 101, the two adjacent sealing structures 43 can better fit together, thereby improving the sealing effect between the upper door assembly 4 and the lower door assembly 4.

[0135] In some embodiments, a positioning hole 64 is provided on the side of the door frame 6, a first mounting hole is provided on the side of the upper door assembly 4, a second mounting hole is provided on the side of the lower door assembly 4, and a rotating shaft 63 passes through the positioning hole 64, the first mounting hole and the second mounting hole to rotatably connect the side of the door frame 6 with the upper door assembly 4 and the lower door assembly 4.

[0136] In the above embodiment, the door frame 6 and the upper door assembly 4 and the lower door assembly 4 are rotatably connected by the positioning hole 64 and the first assembly hole and the second assembly hole in conjunction with the rotating shaft 63, which is simple in structure and stable in connection.

[0137] In some embodiments, a plurality of positioning holes 64 are provided along the side of the door frame 6, at least some of the positioning holes 64 are located on the edge of the upper door assembly 4 away from the lower door assembly 4, at least some of the positioning holes 64 are located between the upper door assembly 4 and the lower door assembly 4, and at least some of the positioning holes 64 are located on the edge of the lower door assembly 4 away from the upper door assembly 4. In the above embodiment, by setting multiple positioning holes 64 along the side of the door frame 6 and distributing the positioning holes 64 at multiple positions along the edge of the upper door assembly 4 and the lower door assembly 4, the coaxiality of the upper door assembly 4 and the lower door assembly 4 is improved, and the relative height error between the two doors during rotation is reduced, thereby further improving the sealing effect between the upper door assembly 4 and the lower door assembly 4.

[0138] Specifically, in this embodiment, three positioning holes 64 are provided at the upper, middle and lower positions on the left side of the door frame 6.

[0139] In some embodiments, the air oven further includes a linkage component 7.

[0140] The linkage component 7 is located between the upper door assembly 4 and the lower door assembly 4. The linkage component 7 is driven to have a disengaged state and a linked state. When the linkage component 7 is in the disengaged state, the upper door assembly 4 and the lower door assembly 4 can rotate independently to open and close. When the linkage component 7 is in the linked state, the upper door assembly 4 and the lower door assembly 4 can rotate synchronously to open and close.

[0141] In the above embodiments, during dual-cavity cooking, the linkage component 7, which is switched to the disconnected state, can drive one of the upper door component 4 and the lower door component 4 to open and close independently, making it easy to check the cooking status in the corresponding cavity; when the dual cavities are combined into a large cavity for cooking, the linkage component 7, which is switched to the linkage state, can drive the upper door component 4 and the lower door component 4 to open and close synchronously, eliminating the need to open and close the two doors one by one, making the operation more convenient.

[0142] Specifically, the linkage component 7 is located between the upper door assembly 4 and the lower door assembly 4, and can be located inside the door assembly or inside the door handle. The linkage component 7 can be specifically configured as a linkage lock or other mechanism.

[0143] In some embodiments, the upper door assembly 4 includes an upper handle 44, the lower door assembly 4 includes a lower handle 44, and the linkage component 7 is disposed between the upper handle 44 and the lower handle 44. The linkage component 7 includes an operating member 701, a linkage member 702, and a limiting part 703.

[0144] An operating member 701 is slidably disposed on one of the upper handle 44 and the lower handle 44; a linkage member 702 is disposed on one of the upper handle 44 and the lower handle 44 and is throttle-connected to the linkage member 702. The linkage member 702 is driven by the operating member 701 to have a first position where one of the upper handle 44 and the lower handle 44 is retracted, and a second position where one of the upper handle 44 and the lower handle 44 is extended; a limiting part 703 is disposed on the upper handle 44 and the lower handle 44. The other one; when the linkage 702 is in the first position, it disengages from the limiting part 703, so that the linkage component 7 is in a disengaged state, and the upper handle 44 and the lower handle 44 can be driven independently to drive the upper door assembly 4 and the lower door assembly 4 to rotate respectively; when the linkage 702 is in the second position, it engages with the limiting part 703, so that the linkage component 7 is in a linked state, and the upper handle 44 and the lower handle 44 can be driven simultaneously to drive the upper door assembly 4 and the lower door assembly 4 to rotate synchronously.

[0145] In the above embodiment, a linkage component 7 is provided on the handle to facilitate switching operations when the user drives the door component using the handle. By having the operating part 701 on one handle drive the linkage component 702 to engage with the limiting part 703 on another handle, the two handles can be driven simultaneously, resulting in a simple structure and convenient operation.

[0146] Specifically, in this embodiment, the operating member 701 is slidably disposed on the upper handle 44 and extends inward. The extended portion is connected to the linkage member 702 disposed within the upper handle 44. The bottom of the upper handle 44 has a clearance opening corresponding to the bottom position of the linkage member 702. The bottom of the linkage member 702 can retract into the upper handle 44 or extend out of the upper handle 44 through the clearance opening. The limiting part 703 is disposed on the top of the lower handle 44 and its position corresponds to the position of the clearance opening. When the user pushes the operating member 701 downward, the linkage member 702 moves downward. The bottom of the linkage member 702 extends out of the clearance opening and engages with the limiting part 703, so that the upper handle 44 and the lower handle 44 can be driven simultaneously.

[0147] Furthermore, in this embodiment, the limiting part 703 is set as a limiting port at the top of the lower handle 44, and the bottom of the linkage member 702 extending out of the clearance port extends into the limiting port for engagement. As an alternative implementation, the limiting part 703 is set as two limiting bosses at the top of the lower handle 44, and the bottom of the linkage member 702 extending out of the clearance port extends between the two limiting bosses for engagement.

[0148] In one alternative implementation, such as Figure 2 , Figures 22-25 As shown, a rotary motor 103 is provided in the bottom of the housing 1, and the output end of the rotary motor 103 extends into the cavity 101. The air oven also includes a grill rack 8 that is connected to the output end of the rotary motor 103. This ensures that the food on the grill rack 8 is heated evenly.

[0149] The skewer rack 8 includes: a hanging rack 81 and skewers 82.

[0150] The skewer rack 81 is provided with a skewer rack hole 8111; the skewers 82 are detachably installed on the skewer rack 81. The skewers 82 include a skewer needle 822 and a skewer head 821. The skewer head 821 is provided with: a through part 8211 that passes through the skewer rack hole 8111 to achieve horizontal positioning of the skewer 82; a first positioning part 8212 formed by bending the through part 8211, and the first positioning part 8212 has a limiting plane 82121 for contacting and cooperating with the upper surface of the skewer rack 81 to achieve vertical lower positioning of the skewer 82; and a second positioning part 8214 located at the junction of the skewer head 821 and the skewer needle 822, and the second positioning part 8214 has an abutment surface 82141 for abutting and limiting the skewer head 821 with the periphery of the skewer rack 81.

[0151] In the above embodiment, when the skewer 82 is installed on the skewer rack 81, the through portion 8211 on its skewer head 821 passes through the skewer rack hole 8111 on the skewer rack 81, at least restricting the horizontal movement of the skewer 82. Under the action of gravity, the first positioning portion 8212 on its skewer head 821 contacts and engages with the upper surface of the skewer rack 81 through the limiting plane 82121, reliably limiting the lower movement of the skewer 82. The abutting surface 82141 of the second positioning portion 8214 on the skewer head 821 abuts against the periphery of the skewer rack 81. The connecting part 8211 and the second positioning part 8214 work together to further prevent the skewer 82 from moving horizontally and rotating around the vertical axis. Compared with the unreliable lower limit and horizontal limit in related technologies, which cannot restrict rotation, the addition of the limiting plane 82121 and the abutment surface 82141 changes the original point contact or line contact limit to surface contact, effectively improving the connection between the skewer 82 and the hanging rack 81. The positioning constraint is better, and the skewer 82 is not easy to shift or shake after being installed in place, meeting the usage requirements.

[0152] It should be noted that the surface contact method, on the one hand, increases the contact area, thereby improving the support and connection reliability, and on the other hand, it can also increase the frictional resistance of movement, further improving the reliability of the limit.

[0153] Specifically, to prevent the skewer 82 from rotating, at least the tip 821 of the skewer 82 can have a non-circular cross-section, further improving the reliability of the connection between the skewer 82 and the skewer holder 81. Specifically, the cross-section of the skewer 82 can be rectangular for ease of manufacturing; correspondingly, the skewer holder hole 8111 is also rectangular. Of course, the cross-section of the skewer 82 can also be irregular. To increase the contact area during surface contact, the skewer 82 can be made by bending a flat rod. Utilizing the characteristic that the skewer 82 has a certain deformability, after the tip 821 passes through the through-hole 8211 into the skewer holder hole 8111, the needle 822 is pulled radially outward, making the opening of the hook-shaped structure formed by the tip 821 larger. The limiting plane 82121 of the first positioning part 8212 contacts the skewer holder 81, the needle 822 is released, and the abutting surface 82141 of the second positioning part 8214 abuts against the periphery of the skewer holder 81, completing the assembly of the skewer 82. Alternatively, a limiting groove can be formed on the top surface of the hanging frame 81. The limiting groove is configured to at least partially accommodate the groove of the first positioning part 8212. By utilizing the limiting sidewall of the limiting groove, the limiting reliability is further improved, and movement and rotation in the horizontal plane are prevented. Furthermore, the limiting groove can be configured with an upper guide slope for easy assembly.

[0154] In some embodiments, the first positioning part 8212 is formed by bending the top end of the through part 8211 toward the side away from the skewer 822. The first positioning part 8212 is formed by bending the top end of the through part 8211 toward the side away from the skewer 822, so that the limiting plane 82121 is stably attached to the upper surface of the hanging rack 81, and the vertical lower limiting effect is stable; at the same time, the first positioning part 8212 and the second positioning part 8214 are distributed on different sides of the hanging rack 81, forming a bidirectional clamping constraint, further strengthening the horizontal limiting and anti-rotation effect, making the positioning more stable, and the skewers 82 are not easy to shift or flip.

[0155] In some embodiments, the first positioning part 8212 and the second positioning part 8214 are directly connected; in other embodiments, they are indirectly connected. The direct connection between the first positioning part 8212 and the second positioning part 8214 of the skewer head 821 results in a simple structure; the indirect connection facilitates the placement of other functional components between them. The connection between the first positioning part 8212 and the second positioning part 8214 ensures synchronized limiting actions, further improving the positioning reliability of the skewer 82 and effectively reducing deformation and loosening.

[0156] In some embodiments, the grill skewer 82 further includes a lifting portion 8213.

[0157] The lifting part 8213 is formed on the skewer head 821 or installed on the top of the skewer head 821, and the lifting part 8213 is connected between the first positioning part 8212 and the second positioning part 8214.

[0158] In the above embodiment, a lifting part 8213 is provided, which makes it convenient for users to hold and lift the skewers 82 for picking and placing, making the operation convenient; moreover, the lifting part 8213 has a relatively low temperature, which can avoid the hands from directly contacting the heated parts, prevent burns, and improve the safety of use. The lifting part 8213 is connected and arranged between the first positioning part 8212 and the second positioning part 8214, which improves the overall structural integrity and also facilitates the formation of a hollow structure in the skewer tip 821, making it easier to pick up and promoting heat dissipation.

[0159] Specifically, the lifting part 8213 is inverted U-shaped, forming a hollow structure in the skewer head 821. The lifting part 8213 adopts an inverted U-shape and forms a hollow structure in the skewer head 821. The hollow design increases the heat dissipation area, reduces the temperature of the lifting part 8213, and further avoids the risk of burning hands; at the same time, this shape makes it easier for fingers to insert and hold, making operation more convenient and the structure simple.

[0160] In some embodiments, the through-hole 8211 is parallel to the skewer 822. The parallelism between the through-hole 8211 and the skewer 822 ensures that the skewer 82 is in the correct position after assembly, resulting in higher precision in the limiting fit and effectively avoiding skewing and offset. It also ensures that the skewer 822 remains vertical after installation. Furthermore, the overall structure is regular and the force is evenly distributed, further improving the overall structural strength and stability.

[0161] In some embodiments, the hanging rack 81 includes: a hanging plate 811, a support rod 812, and a base 813.

[0162] Multiple mounting holes 8111 are spaced circumferentially along the edge of the hanging plate 811. The plate surface of the hanging plate 811 is bent downward to form a folded edge 8112. The second positioning part 8214 abuts against the folded edge 8112. The base 813 is connected to the output end of the rotary motor 103. The support rod 812 is used to support and install the hanging plate 811 on the base 813. The hanging plate 811 and the base 813 are respectively detachably set at both ends of the support rod 812.

[0163] In the above embodiment, the edge of the hanging tray 811 is bent downward to form a folded edge 8112, which has high structural strength. The folded edge 8112 serves as an abutment point and cooperates with the second positioning part 8214 to form a surface contact abutment. The positioning contact surface is regular, and the abutment limit is stable and reliable, ensuring that the folded edge 8112 blocks and limits the side of the grill skewer 82, preventing the grill skewer 82 from shifting or rotating. The folded edge 8112 is formed by bending the hanging body as a whole, without the need for additional limiting parts, resulting in a simple structure, convenient processing, and high overall strength. The hanging tray 811, support rod 812, and base 813 adopt a detachable assembly method, allowing the grill rack to be disassembled and stored, greatly reducing the storage space occupied and making storage and transportation more convenient. It also facilitates the individual cleaning of the hanging tray 811, support rod 812, and base 813 after disassembly, and facilitates individual inspection and replacement.

[0164] In some embodiments, the hanging plate 811 is further provided with a plurality of weight-reducing structures 8114 on its surface to reduce the weight of the hanging plate 811.

[0165] In some embodiments, the base 813 is provided with an oil collection tray to collect oil and impurities dripping during baking, making it easy to disassemble and clean.

[0166] In some embodiments, the two ends of the support rod 812 are detachably connected to the hanging plate 811 and the base 813 via a first plug-in structure and a second plug-in structure, respectively.

[0167] The assembly process utilizes a plug-in structure, making assembly and disassembly simple and quick, resulting in high efficiency. Furthermore, the plug-in joints provide precise positioning and a secure connection that is not easily loosened. The plug-in structure is simple in construction, has low processing and assembly costs, and is also easy to disassemble, store, and clean.

[0168] Specifically, the first insertion structure includes a positioning hole and a positioning post, one of which is disposed on the support rod 812, and the other is disposed on the hanging plate 811. The second insertion structure also includes a positioning hole and a positioning post, one of which is disposed on the support rod 812, and the other is disposed on the base 813.

[0169] In some embodiments, such as Figures 26-32 As shown, the housing 1 is provided with a storage compartment 19, and the air oven also includes a retrieval clip 9 disposed in the storage compartment 19.

[0170] Specifically, the air fryer is equipped with a food tongs 9 and a dedicated storage compartment 19. After the air fryer has been cooking, the frying drum 21, tray, and other components are very hot. The food tongs 9 can be used to safely pick up the hot components, effectively avoiding burns to the hands and making it safer to use. The food tongs 9 are stored in the storage compartment 19 of the shell 1, which is neatly stored and easy to use. This prevents the food tongs 9 from being lost and eliminates the need for extra searching. The convenience of storage and retrieval is greatly improved, and the compact layout makes high space utilization.

[0171] Furthermore, the frying drum 21 or tray is provided with a connecting structure 2105, and the retrieval clip 9 is adapted to connect to the connecting structure 2105 through the clamping port 910. The rear end of the rocker arm 92 is also provided with a tail hole 911 for easy gripping and can also be used for hanging. The side wall of the storage compartment 19 is provided with a notch 1901 corresponding to the opening side, and the notch 1901 corresponds to the tail hole 911 for easy retrieval through the notch 1901. Furthermore, the storage compartment 19 is set on the top of the side wall of the air fryer, making it more convenient for users to retrieve.

[0172] The retrieval clip 9 includes: a gripping part 91, a rocker plate 92, a buckle plate 93, a trigger part 94, a locking assembly, and the trigger part 94.

[0173] The gripping part 91 is a shell structure with a bottom opening 917 and a cavity 916. A mounting groove 912 is provided on the top surface of the gripping part 91, and a through hole 913 is provided at the front end of the gripping part 91. The mounting groove 912 and the through hole 913 communicate with the cavity 916. A pivot shaft 914 is provided inside the cavity 916 of the gripping part 91 near the through hole 913. The buckle plate 93 has a clamping part 931 and a pivoting part 932. The buckle plate 93 is pivotally mounted on the pivot shaft 914, and at least the clamping part 931 is located outside the cavity 916 of the gripping part 91 through the through hole 913, forming a clamping opening 910 between the clamping part 931 and the gripping part 91. The rocker arm 92 has a latch 921, and the rocker arm 92 is fixedly connected to the buckle plate 93 to form a rotating arm that can rotate around the pivot shaft 914. The locking assembly has a sliding mechanism that can slide in the front-back direction. The movable locking tongue 96 is used to engage with the latch 921 for limiting; the trigger part 94 is slidably disposed in the mounting groove 912 in the vertical direction, and the trigger part 94 is connected to the locking tongue 96 in a driving connection; the rotating arm has a first position of locking and a second position of unlocking. When the rotating arm is in the first position, the locking tongue 96 engages and locks with the latch 921, restricting the swing of the rotating arm, locking the opening of the clamping mouth 910, and the rocker plate 92 blocks the opening 917 side of the gripping part 91; when force is applied to the trigger part 94, the trigger part 94 drives the locking tongue 96 to disengage from the latch 921, and the rotating arm swings outward to the second position, so that the free end of the rocker plate 92 moves away from the gripping part 91 and the clamping mouth 910 opens; the first elastic member 98 is installed between the buckle plate 93 and the gripping part 91, and the first elastic member 98 is in a compressed state when the rotating arm is in the first position.

[0174] In the above embodiments, the retrieval clamp 9 cooperates with the locking assembly, the trigger part 94, and the rotating arm with the latch 921. When the clamping port 910 clamps the object and switches to the locked state, the locking tongue 96 engages with the latch 921 to limit the opening of the clamping port 910, which can firmly lock the opening of the clamping port 910. It can stably clamp heavy objects without the need for continuous clamping force from the hand, greatly reducing the labor load on the hands, and is particularly suitable for heavy-duty retrieval scenarios in the kitchen. In addition, the pivot shaft 914 is set at the through hole 913 at the front end of the grip part 91. The front-positioned layout of the pivot shaft 914 makes the structural force distribution more reasonable. Since the clamping force point is close to the clamping port 910, the lever arm layout is reasonable. When clamping heavy objects, the load can be directly transferred to the pivot shaft 914 position, reducing the deformation and stress concentration of the grip part 91, improving the overall structural strength and clamping stability, and making it less likely to loosen or be damaged under heavy-duty conditions. The grab clip 9 has a simple and compact structure. It can be quickly unlocked by pressing the trigger part 94, which opens the clamping opening 910. It is easy to operate and the opening and closing is smooth.

[0175] It should be noted that the free end of rocker 92 refers to the end of rocker 92 furthest from the pivot axis 914 of buckle 93, which is the farthest point of the rotating arm from the grip 91 in the unlocked state. The rotating arm is composed of rocker 92 and buckle 93, which offers greater assembly flexibility and is easier to manufacture compared to a one-piece design. Specifically, rocker 92 and buckle 93 are detachably fixed together via threaded connectors, ensuring a reliable connection and easy assembly / disassembly.

[0176] Specifically, a first elastic element 98 is provided. When the latch 96 disengages from the latch 921, the rotating arm can quickly swing from the first position to the second position under the rebound action of the first elastic element 98. After the rotating arm quickly opens, the retrieval clamp 9 is unlocked. Compared with the method relying on gravity, the action response is faster, the opening and closing is more crisp, it is not affected by the placement posture, the unlocking action is stable and reliable, and the unlocking is smoother. Since the elastic element remains compressed in the locked state, it will continuously apply an elastic force that tends to open the rotating arm. This force makes the latch 921 more tightly pressed against the latch 96, making the two more firmly engaged and preventing loosening under vibration or accidental contact, making it less likely to be accidentally opened; it can also help maintain the clamping and locking state, further enhancing the clamping stability.

[0177] Furthermore, the first elastic element 98 is installed near the pivot shaft 914. Positioning the first elastic element 98 beside the pivot shaft 914 results in a short lever arm, making torque transmission more efficient. During locking, the elastic force continuously presses against the latch 921 and the bolt 96, improving locking reliability; upon unlocking, the elastic force efficiently drives the rotating arm to rotate, allowing the clamping port 910 to open rapidly. Moreover, this arrangement reduces the load on the first elastic element 98, delaying fatigue aging and extending its service life.

[0178] Furthermore, the rocker arm 92 has an assembly groove, and the buckle plate 93 has a corresponding through hole 933. The bottom end of the first elastic element 98 is fixed in the assembly groove, and the top end of the first elastic element 98 passes through the through hole 933 and connects to the gripping part 91. The first elastic element 98 passes through the through hole 933 and its bottom end is fixed in the assembly groove, ensuring reliable installation and positioning. This effectively constrains the extension and retraction direction of the elastic element, eliminates problems such as skewness and interference, and ensures smooth operation of the rotating arm.

[0179] Furthermore, the gripping part 91 also includes a mounting bracket 915, which has a trigger hole and a sliding cavity. The trigger part 94 passes through the trigger hole and connects to the locking tongue 96, which is located in the sliding cavity. The locking assembly is mounted inside the cavity 916 via the mounting bracket 915. The sliding cavity guides and limits the locking tongue 96, ensuring that it slides smoothly along a preset direction and avoiding deviation or jamming. The trigger hole limits the movement path of the trigger part 94, ensuring precise transmission and engagement. In addition, the mounting bracket 915 provides a neat overall structural layout, secure component positioning, good operational stability, and facilitates overall assembly, improving assembly efficiency. The front end of the mounting bracket 915 also has a groove for mounting the top end of the first elastic element 98, which is fixedly installed in the groove.

[0180] Furthermore, a limiting rib 922 is provided on the bottom front surface of the rocker arm 92 to limit the maximum pivot angle of the rotating arm. With the limiting rib 922 on the bottom front surface of the rocker arm 92, when the rotating arm rotates to a preset angle, the limiting rib 922 abuts against the inner front side of the gripping part 91, limiting the opening range of the clamping opening 910 and the swing range of the rotating arm. This facilitates clamping while preventing the rotating arm from swinging too far, thus avoiding inconvenience in gripping operations.

[0181] Furthermore, a buffer pad 97 is provided at the front end of the snap plate 93, located within the clamping opening 910. The buffer pad 97 within the clamping opening 910 serves two purposes: firstly, it increases the friction of the clamping contact surface, preventing the clamped object from slipping and falling off, thus improving clamping stability; secondly, it buffers the impact force during clamping, preventing hard components from scratching and damaging the clamped item, and is suitable for handling various objects. In addition, the buffer pad 97 is fixed to the grip 91, resulting in less wear and tear compared to the snap plate 93 which is designed for reciprocating movement, making it less prone to falling off and aging, and extending its service life; moreover, when clamping food containers, the buffer pad 97 contacts the outer side of the clamped item, minimizing contact with food and promoting hygiene. The front end of the snap plate 93 also has a recessed groove, within which the buffer pad 97 can be detachably installed for easy removal and replacement. The buffer pad 97 is made of an elastic material, such as silicone.

[0182] Furthermore, the locking assembly also includes a second elastic element 99, which is disposed between the gripping part 91 and the latch 96. The second elastic element 99 is used to reset the latch 96 and maintain the engagement state between the latch 96 and the latch 921. The second elastic element 99 provides a continuous reset force to the latch 96, and after unlocking, it can push the latch 96 to automatically return to its original position, ensuring that the next engagement action will proceed normally. Simultaneously, under normal conditions, the elastic force keeps the latch 96 pressed tightly against the latch 921, improving the engagement tightness, effectively preventing the latch 96 from accidentally slipping and disengaging, enhancing locking reliability, and ensuring smooth locking and unlocking actions and stable operation.

[0183] In some embodiments, the locking tongue 96 includes a transmission part and an engagement part.

[0184] The transmission part is provided with a transmission through hole 961 and a first inclined surface 964. The first inclined surface 964 is adjacent to the front side of the transmission through hole 961 and slopes downward toward the bottom of the transmission through hole 961. The trigger part 94 is provided with a second inclined surface 941, which is in frictional engagement with the first inclined surface 964. The engaging part includes a first engaging surface 963 and a third inclined surface 962. The first engaging surface 963 is located on the upper surface of the engaging part, and the third inclined surface 962 slopes away from the transmission part and intersects with the first engaging surface 963. The latch 921 is provided with a fourth inclined surface 9211 and a second engaging surface 9212. The inclination direction of the fourth inclined surface 9211 is the same as the inclination direction of the third inclined surface 962.

[0185] In the above embodiment, the second inclined surface 941 of the trigger part 94 and the first inclined surface 964 of the locking tongue 96 are in inclined face contact. When the trigger part 94 is pressed, the second inclined surface 941 squeezes the first inclined surface 964, which can smoothly convert the vertical force into the horizontal sliding thrust of the locking tongue 96. The transmission is smooth, the structure is simple, and it is not easy to get stuck. The locking tongue 96 and the latch 921 adopt a structure of inclined surfaces in the same direction and mutually cooperating locking surfaces. When locked, the locking surfaces are in close contact and fit together, and the limiting is reliable. During the unlocking and locking process, the inclined surfaces can play a guiding role. During the upward movement of the latch 921, the fourth inclined surface 9211 squeezes and pushes the locking tongue 96 forward a certain distance. When the two inclined surfaces reach the edge, the latch 921 retracts under the action of the second elastic element 99, so that the first locking surface 963 of the locking tongue 96 and the second locking surface 9212 of the latch 921 are locked together. The two inclined surfaces can guide the components to be smoothly aligned, reduce the biting resistance, and make the locking and unlocking actions smoother. The overall fitting accuracy and running stability are greatly improved.

[0186] The retrieval clip 9 in this embodiment can achieve heavy-duty locking and quick unlocking without continuous gripping force. The specific clamping and releasing process is as follows: First, let's explain the object clamping and locking process: The initial state of the retrieval clamp 9 is the locked state. At this time, the rotating arm composed of the buckle plate 93 and the rocker plate 92 is in the first locked position, and the first elastic member 98 installed between the grip part 91 and the buckle plate 93 is in a compressed state. At this time, the second elastic member 99 of the locking assembly drives the locking tongue 96 to maintain the retracted and engaged position. The first engaging surface 963 of the locking tongue 96 and the second engaging surface 9212 of the latch 921 of the rocker plate 92 are tightly fitted and locked. The clamping opening 910 maintains a fixed closed opening. At the same time, the rocker plate 92 blocks the opening 917 on the bottom side of the grip part 91, and the retrieval clamp 9 is in a stable locked state.

[0187] In use, hold the gripping part 91 and align the clamping opening 910 at the front of the grappling clamp 9 with the object to be clamped (suitable for air fryer drums 21, trays, etc. with connecting structures 2105, or conventional containers with edges). Manually press the rotating arm inward to make the buckle plate 93 and the rocker plate 92 swing inward around the pivot axis 914 at the front of the gripping part 91. During the swinging process, the fourth inclined surface 9211 of the latch 921 and the third inclined surface 962 of the latch 96 press against each other and guide each other. The matching structure of the inclined surface can reduce the biting resistance and push the latch 96 to overcome the elastic force of the second elastic element 99 and slide forward slightly to make room for the latch 921 to swing.

[0188] After the clamping opening 910 is engaged and clamps the object to be clamped, the hand pressure is released. The locking tongue 96 automatically returns to its original position under the reset force of the second elastic element 99. The first engaging surface 963 of the locking tongue 96 precisely engages with the second engaging surface 9212 of the latch 921, completing the limit locking again. The rotating arm remains stably in the first locked position. At this time, the first elastic element 98 continues to compress and apply elastic thrust, further tightening the engagement structure between the latch 921 and the locking tongue 96, preventing loosening caused by vibration or accidental contact, and firmly locking the clamping opening of the clamping opening 910. Heavy objects (such as those containing food) can be stably clamped without the need for continuous hand clamping force, completing the object clamping and locking operation. Meanwhile, the buffer pad 97 inside the clamping opening 910 of the buckle plate 93 is closely attached to the surface of the object, which not only increases the clamping friction to prevent slippage and drop, but also avoids the hard structure from scratching the object to be clamped, thus improving the clamping stability and safety.

[0189] After the gripper moves to the target position, the retrieval clamp 9 performs the unlocking and releasing process: When the object needs to be released after the transfer is completed, there is no need to manually pry the clamp. Simply press the trigger part 94 embedded in the mounting groove 912 on the top surface of the grip part 91 vertically downward. The trigger part 94 slides vertically downward along the mounting groove 912. The second inclined surface 941 at its bottom presses against the first inclined surface 964 of the transmission part of the latch 96, converting the vertical pressing force into the horizontal forward sliding thrust of the latch 96. This causes the latch 96 to move smoothly forward along the sliding cavity of the mounting frame 915, disengaging from the latch 921 of the rocker arm and releasing the locking limit on the rotating arm.

[0190] After the locking constraint is released, the first elastic element 98, which was originally in a compressed state, quickly rebounds, driving the rotating arm to swing outward automatically around the pivot axis 914, so that the rotating arm quickly switches from the first locked position to the second unlocked position. During the swing, the limiting rib 922 on the bottom front surface of the rocker 92 abuts against the inner side of the front front of the grip 91, limiting the maximum pivot angle of the rotating arm and preventing the opening angle from being too large and affecting the operation. At the same time, the free end of the rocker 92 moves away from the grip 91, and the clamping opening 910 opens completely and smoothly, releasing the clamped object and completing the object release operation.

[0191] When the pressure on the trigger 94 is released, the locking tongue 96 automatically slides back into position under the reset action of the second elastic element 99, and the trigger 94 resets simultaneously. At this time, the finger grips and retracts the rocker 92 inward, the latch 921 and the locking tongue 96 re-engage, and the retrieval clip 9 returns to its initial locked standby state.

[0192] For daily storage, the tail hole 911 at the rear end of the rocker 92 can be used to quickly retrieve or hang the storage through the side wall notch 1901 of the air oven storage compartment 19, which is suitable for convenient use and neat storage needs in the kitchen.

[0193] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by this application.
