Description

Technical Field

[0001] The present application belongs to the technical field of kitchenware, and specifically relates to an air fryer. Background Art

[0002] As people's living standards continue to improve, people use more and more cooking utensils in the kitchen, and the requirements for cooking utensils are getting higher and higher. Among various cooking utensils, various baking equipment used for baking meat products, bread and pastries, etc. are becoming more and more popular. For example, people like ovens with various functions, air fryers, etc.

[0003] The air fryer includes a body and a pot body that can be pushed and pulled. Existing air fryers usually set a guide rail in the body cavity to guide the pushing and pulling of the pot body. Since there is sliding friction between the pot body and the body, the resistance is relatively large during pushing and pulling, especially when there are more ingredients in the pot body, the sliding friction resistance between the pot body and the body is relatively large, and the user needs to apply a large force to achieve the pushing and pulling of the body from the inside of the body. At the same time, in order to avoid direct contact with food or rust, a coating will be sprayed on the surface of the pot body, and when the pot body is pulled out, the coating of the pot body will be scratched due to friction and sliding with the inner cavity. In order to avoid scratches and damage to the coating during the repeated pushing and pulling of the pot body, the existing technology usually sets the inner cavity of the body as a plastic inner cavity, but since a large amount of heat will be gathered inside the body when the air fryer is working, and the high temperature resistance of plastic is poor, it is easy to produce odor under high temperature conditions, which reduces the user experience. Even during the long-term heating process, the plastic inner cavity melts to cause deformation, reducing the service life of the inner cavity.

[0004] In the related technology, for example, patent CN202221377113.X discloses an air fryer, which is provided with a moving device at the bottom of the inner pot body, and the moving device enables the inner pot body and the inner pot placement cavity of the main frame to form a translational sliding push-pull fit. The device is complex to install, and it relies on the table top for placing the main frame to form a sliding push-pull fit. Therefore, it has high requirements on the flatness and strength of the table top, and there is a risk of damaging the table top in long-term use; and the inner pot placement cavity is completely exposed to the table top, which will cause water and oil to leak onto the table top during cooking, thereby increasing the user's cleaning burden and reducing the user experience. Utility Model Content

[0005] The present application provides an air fryer to solve the technical problem that the plastic cooking cavity of a conventional air fryer is prone to emitting odor or even melting under high-temperature heating.

[0006] The technical solution adopted in this application is:

[0007] An air fryer comprises a pot body and a body with a cooking cavity, the side wall of the body is provided with an opening connected to the cooking cavity, the pot body moves along the opening to be pushed into or moved out of the cooking cavity, the cooking cavity is a metal inner cavity, and at least one of the metal inner cavity and the pot body is provided with a rolling element for reducing the movement resistance of the pot body.

[0008] The air fryer of the present application comprises a pot body and a body with a cooking cavity, wherein at least one of the cooking cavity and the pot body is provided with a rolling member. By providing the rolling member, when the pot body is pushed into the cooking cavity from the outside of the body or pulled out of the cooking cavity from the body, the rolling of the rolling member assists the movement of the pot body. Compared with the sliding friction between the pot body and the cooking cavity in the traditional air fryer, the pot body and the cooking cavity in the air fryer of the present application are rolling friction, and the resistance of the pot body is small when pushing and pulling. Even if more food is placed in the pot body, the user only needs to apply a small force to achieve the pushing and pulling of the pot body, which improves the user's use experience; secondly, since the pot body and the cooking cavity in the present application are rolling friction, the coating on the pot body will not be affected during the pushing and pulling process of the pot body, which effectively ensures the integrity of the coating and provides a guarantee for the service life of the pot body; furthermore, since the inner wall of the cooking cavity is made of metal, no melting phenomenon will occur when high-temperature cooking is performed, thereby avoiding the impact on the food, ensuring food safety while avoiding the occurrence of the phenomenon that the traditional plastic cooking cavity emits odor under high temperature, thereby preventing the precipitation of harmful substances, and improving the user's use experience in many aspects.

[0009] The air fryer of the present application also includes the following additional technical features:

[0010] The rolling element is arranged on the machine body, and a partial area of ​​the rolling element protrudes from the inner wall of the cooking cavity to contact the pot body.

[0011] Arranging the rolling member on the machine body can, on the one hand, simplify the structural design of the pot body, thereby reducing the difficulty of processing and manufacturing the pot body, while saving the space occupied by the rolling member in the pot body while keeping the overall size of the pot body consistent, thereby reserving more cooking space for the pot body and increasing the volume of food that the pot body can accommodate; that is, compared with arranging the rolling member on the pot body, arranging the rolling member on the machine body can make the pot body have a larger capacity for holding food, thereby increasing the food holding capacity of the air fryer.

[0012] A plurality of rolling members are provided along the length direction of the cooking cavity, and the rolling members at least cover the front half of the moving path of the pot body when it is pushed into the cooking cavity.

[0013] The rolling member is arranged to cover at least the front half of the moving path of the pot body when it is pushed into the cooking cavity. When the pot body is pushed into the cooking cavity, when the end of the pot body facing the cooking cavity just enters the cooking cavity, rolling friction with the cooking cavity can occur with the assistance of the rolling member. The rolling member can assist the pot body in the initial stage of pushing the pot body in, thereby achieving auxiliary resistance reduction of the rolling member during the complete movement of the pot body, thereby facilitating the smooth movement of the pot body.

At the same time, the guide rail can also guide the movement of the pot body, so that the pot body moves along the length direction of the guide rail, avoiding the occurrence of jamming between the pot body and the cooking cavity due to movement deviation during the pushing and pulling process, improving the smoothness of pushing and pulling the pot body, and enhancing the user experience.

[0016] The machine body is provided with a bracket for positioning the rolling element, the bracket is provided with a rolling groove adapted to the rolling element, and the bottom wall and / or the side wall of the cooking cavity are provided with an avoidance groove for avoiding the rolling element so that the rolling element protrudes.

[0017] The avoidance groove provides an avoidance space for the protrusion of the rolling part. The rolling groove arranged on the bracket can provide a placement position for the rolling part and limit the rolling part when it rolls, preventing the rolling part from being dislocated, thereby providing a guarantee for the smooth pushing and pulling of the pot body.

[0018] The bracket is detachably connected to the body.

[0019] The bracket is arranged to be detachably connected to the body. On the one hand, it simplifies the processing design of the bracket and the body and facilitates their respective processing and molding. On the other hand, when the bracket is deformed or even damaged due to various factors during transportation or use and needs to be replaced, the corresponding performance can be restored by replacing the bracket, thereby reducing maintenance costs. Furthermore, the bracket is detachably connected to the body, which is convenient for users to replace it independently.

[0020] The body is provided with a rolling groove integrally formed therewith, the rolling element is a ball, the rolling groove is adapted to the ball, the bottom wall or the side wall is provided with a limiting hole for limiting the ball, and the inner diameter of the limiting hole is smaller than the outer diameter of the ball.

[0021] The rolling groove provides a placement position for the rolling element, and the rolling groove is integrally formed in the machine body, which saves assembly steps and improves the assembly efficiency of the whole machine. The limiting holes set on the bottom wall or the side wall can limit the rolling element when it rolls, preventing the rolling element from dislocating, thereby ensuring the smooth pushing and pulling of the pot body.

[0022] The machine body includes a base and a cover plate covering the top of the base to form the bottom wall of the cooking cavity, the base is provided with a first positioning column protruding toward the cover plate, the top of the first positioning column is recessed inwardly to form the rolling groove, and the cover plate is provided with the limiting hole; and / or, the machine body includes a base and a side enclosure frame provided above the base and cooperating with the base to form the cooking cavity, the side enclosure frame includes a first side enclosure panel for forming the side wall of the cooking cavity and a second side enclosure panel fixed to the periphery of the first side enclosure panel, the second side enclosure panel is provided with a second positioning column protruding toward the first side enclosure panel, one end of the second positioning column is recessed inwardly to form the rolling groove, and the first side enclosure panel is provided with the limiting hole.

[0023] By arranging a first positioning column protruding toward the cover plate on the base and the top of the first positioning column is recessed inward to form a rolling groove, the structural design is simple, the integrity of the base is improved, and the structural strength of the base can be improved to a certain extent, and the assembly efficiency of the whole machine is improved. By arranging a second positioning column protruding toward the first side panel on the second side panel and one end of the second positioning column is recessed inward to form a rolling groove, the structural design is simple and compact, the integrity of the second side panel is improved, and the structural strength of the second side panel can be improved to a certain extent, and the assembly efficiency of the whole machine is improved.

[0024] A heating plate is arranged at the bottom of the machine body, a hot air assembly is arranged at the upper part of the machine body, and the machine body is provided with two rows of rolling elements separated at both sides of the heating plate.

[0025] By respectively arranging the hot air component and the heating plate on the upper and lower parts of the machine body, when heating and cooking food, the food can be heated three-dimensionally from multiple angles from the upper and lower parts, so that the food is heated evenly. Compared with the method of heating food from a single heat source, the heating method of the heating plate and the hot air component in cooperation with each other in this embodiment can reduce the possibility that the remaining part of the food is still undercooked after part of the food is cooked, and the cooked food tastes better; and the heating method of contact heat transfer between the heating plate and the pot body can also enable the air fryer to have a frying and roasting mode, thereby increasing the diversity of cooking methods for ingredients, thereby improving the user experience; furthermore, the rolling elements are arranged in two rows on both sides of the heating plate. On the one hand, the pot body is supported by the rolling elements on both sides during the pushing and pulling process, and the movement process is relatively smooth, avoiding the occurrence of imbalance caused by uneven force on both sides, and the rolling elements are located on both sides of the heating plate, which will not affect the heating work of the heating plate, thereby providing a guarantee for the stable heating of the air fryer.

[0026] The rolling element is a structure made of metal material. Such a configuration can prevent the rolling element from melting due to heat during high-temperature cooking in the air fryer, thereby preventing harmful substances from being precipitated and avoiding affecting the food.

[0048] like Figure 1 , Figure 6 , Figure 7 As shown, an air fryer comprises a pot body 1 and a body 2 having a cooking cavity 21, a side wall 212 of the body 2 is provided with an opening 22 connected to the cooking cavity 21, the pot body 1 moves along the opening 22 to be pushed into or moved out of the cooking cavity 21, the cooking cavity 21 is a metal inner cavity, at least one of the metal inner cavity and the pot body 1 is provided with a rolling member 3 for reducing the movement resistance of the pot body 1.

[0049] The air fryer of the present application comprises a pot body 1 and a body 2 having a cooking cavity 21, wherein at least one of the cooking cavity 21 and the pot body 1 is provided with a rolling member 3. By providing the rolling member 3, when the pot body 1 is pushed into the cooking cavity 21 from the outside of the body 2 or when the cooking cavity 21 is pulled out from the inside of the body 2, the rolling of the rolling member 3 assists the movement of the pot body 1. Compared with the sliding friction between the pot body 1 and the cooking cavity 21 in the traditional air fryer, the friction between the pot body 1 and the cooking cavity 21 in the air fryer of the present application when pushed and pulled is rolling friction, so that the resistance of the pot body 1 when pushed and pulled is small. Even if a large amount of food is placed in the pot body 1, the user only needs to apply a small force to achieve the pushing and pulling of the pot body 1. Pulling improves the user experience; secondly, since there is rolling friction between the pot body 1 and the cooking cavity 21 in the present application, when the surface of the pot body 1 is provided with a coating, the coating on the pot body 1 will not be affected during the pushing and pulling process of the pot body 1, thereby effectively ensuring the integrity of the coating and providing protection for the service life of the pot body 1; furthermore, since the inner wall of the cooking cavity 21 is made of metal, melting will not occur during high-temperature cooking, thereby avoiding affecting the food, ensuring food safety while avoiding the occurrence of odor in the traditional plastic cooking cavity 21 under high temperature conditions, thereby preventing harmful substances from precipitating, thereby improving the user experience in many aspects.

[0050] It should be noted that the present application does not limit whether the surface of the pot body 1 is provided with a coating, and the surface of the pot body 1 may not be provided with a coating.

[0051] The present application does not limit the structural form of the rolling element 3. In one embodiment, the rolling element 3 is a spherical structure, such as a ball; in another embodiment, the rolling element 3 is a roller; in another embodiment, the rolling element 3 is a bidirectionally rotatable conveying roller.

[0052] As a preferred embodiment of the present application, Figure 4 , Figure 5 As shown, the rolling member 3 is arranged on the body 2, and a part of the rolling member 3 protrudes from the inner wall of the cooking cavity 21 to contact the pot body 1. The rolling member 3 is arranged on the body 2. On the one hand, it can simplify the structural design of the pot body 1, which is convenient for reducing the difficulty of processing and manufacturing the pot body 1, and at the same time, it saves the space occupied by the rolling member 3 in the pot body 1 when the overall size of the pot body 1 is consistent, so that more cooking space can be reserved for the pot body 1, and the volume of food that the pot body 1 can accommodate is increased; that is, compared with the rolling member 3 being arranged on the pot body 1, the rolling member 3 is arranged on the body 2 so that the pot body 1 has a greater ability to hold food, thereby increasing the food holding capacity of the air fryer. The present application does not limit the setting position of the rolling member 3, and it can also be that the rolling member 3 is arranged on the pot body 1, or the rolling member 3 is arranged on both the pot body 1 and the body 2.

[0053] As a preferred embodiment of this implementation, Figure 4 , Figure 5 , Figure 6 As shown, the rolling members 3 are provided in a plurality along the length direction of the cooking cavity 21, and the rolling members 3 at least cover the front half of the moving path of the pot body 1 when it is pushed into the cooking cavity 21. The rolling members 3 are arranged to at least cover the front half of the moving path of the pot body 1 when it is pushed into the cooking cavity 21. When the pot body 1 is pushed into the cooking cavity 21, when the end of the pot body 1 facing the cooking cavity 21 just enters the cooking cavity 21, rolling friction with the cooking cavity 21 can occur under the assistance of the rolling members 3. The rolling members 3 can assist the pot body 1 in the initial stage of the pot body 1 being pushed in, thereby achieving the auxiliary resistance reduction of the rolling members 3 in the complete moving process of the pot body 1, which facilitates the smooth movement of the pot body 1. Similarly, when the pot body 1 is pulled out of the cooking cavity 21, the pot body 1 can be pulled out of the cooking cavity 21 by the rolling friction force under the assistance of the rolling members 3, which provides a guarantee for the smooth pulling out of the pot body 1.

[0054] The rolling element 3 here at least covers the first half of the moving path of the pot body 1 when it is pushed into the cooking cavity 21, so as to Figure 6 The ball shown in the figure is used as an example of the rolling element 3, which means that the ratio of the distance between the rolling element A31 located near the opening 22 of the cooking cavity 21 and the rolling element B32 farthest from the opening 22 to the moving path of the pot body 1 pushed into the cooking cavity 21 is greater than or equal to 1 / 2.

[0055] As another preferred embodiment of this embodiment, Fig.10 As shown, the pot body 1 includes an outer cover shell 11 and a frying basket 12 connected to the outer cover shell 11, and the outer wall surface of the frying basket 12 is provided with a guide rail 13 adapted to the rolling element 3, and the extension length of the guide rail 13 along the movement direction of the frying basket 12 is not less than the coverage length of the rolling element 3 along the movement direction of the frying basket 12. The pot body 1 is set to a structural form consisting of the outer cover shell 11 and the frying basket 12, and the handle of the push-pull pot body 1 can be installed on the outer cover shell 11 to avoid direct contact between the handle and the frying basket 12, increase the stress transfer area between the handle and the frying basket 12 during the process of pushing and pulling the pot body 1, and at the same time, the connection component for connecting the handle on the frying basket 12 is omitted, the structure of the frying basket 12 is simplified, and more storage space for food is reserved for the frying basket 12; the guide rail 13 is set to extend along the movement direction of the frying basket 12. The guide rail 13 is not less than the covering length of the rolling member 3 along the movement direction of the frying basket 12, so that the guide rail 13 can cooperate with the rolling member 3 to assist the rolling of the pot body 1 in the process of pushing the pot body 1 into the cooking cavity 21 or pulling it out of the cooking cavity 21. At the same time, the guide rail 13 can also guide the movement of the pot body 1, so that the pot body 1 moves along the length direction of the guide rail 13, avoiding the occurrence of jamming between the pot body 1 and the cooking cavity 21 due to movement deviation during the pushing and pulling process, improving the smoothness of pushing and pulling the pot body 1, and enhancing the user experience.

[0056] This embodiment does not limit the limiting method of the rolling element 3, and it can adopt any one of the following embodiments:

[0057] Embodiment 1: Figure 2 , Figure 3 As shown, the body 2 is provided with a bracket 23 for positioning the rolling element 3, the bracket 23 is provided with a rolling groove 24 adapted to the rolling element 3, and the bottom wall 211 and / or the side wall 212 are provided with an escape groove 25 for avoiding the rolling element 3 so that the rolling element 3 protrudes. The escape groove 25 provides an escape space for the protrusion of the rolling element 3, and the rolling groove 24 provided on the bracket 23 can provide a placement position for the rolling element 3 and limit the rolling element 3 when it rolls, preventing the rolling element 3 from being dislocated, thereby providing a guarantee for the smooth pushing and pulling of the pot body 1.

[0058] This embodiment does not limit the structural form of the avoidance groove 25, and it can adopt any one of the following examples:

[0059] Example 1: The avoidance groove 25 is in a strip-shaped structure, and a plurality of rolling elements 3 are arranged at intervals along the length direction of the avoidance groove 25. Setting the avoidance groove 25 in a strip-shaped structure can reduce the difficulty of processing the avoidance groove 25 on the body 2, making the forming of the avoidance groove 25 simpler, and helping to reduce the difficulty of manufacturing the body 2.

[0060] Example 2: The number of avoidance grooves 25 is equal to the number of rolling elements 3, and the two correspond one to one. Figure 7 , Figure 8 If there are multiple rolling elements 3 as shown in the figure, an equal number of avoidance grooves 25 need to be set. The avoidance grooves 25 set on the rolling elements 3 with the same number can reduce the opening area on the bottom wall 211 and / or the side wall, thereby improving the structural strength of the bottom wall 211 and / or the side wall to a certain extent, and can reduce the probability of external impurities entering the interior of the body 2 through the avoidance grooves 25, thereby forming effective protection for the components in the body 2.

[0061] This embodiment does not limit the connection method between the bracket 23 and the body 2, and any of the following examples may be used:

[0062] Example 3: The bracket 23 is non-detachably connected to the body 2. The bracket 23 is connected to the body 2 in a non-detachable manner such as welding or gluing, which helps to improve the connection strength between the bracket 23 and the body 2.

[0063] Example 4: The bracket 23 is detachably connected to the body 2. Setting the bracket 23 to be detachably connected to the body 2, on the one hand, simplifies the processing design of the bracket 23 and the body 2, and facilitates the processing and molding of each. On the other hand, when the bracket 23 is deformed or even damaged due to various factors during transportation or use and needs to be replaced, the corresponding performance can be restored by replacing the bracket 23, which reduces the maintenance cost. In addition, the bracket 23 is detachably connected to the body 2, which is convenient for users to disassemble and replace. Compared with the non-detachable connection between the bracket 23 and the body 2 in Example 3, the bracket 23 in this example is convenient for users to replace according to actual needs, and is more economical. This example does not limit the detachable connection method between the bracket 23 and the body 2, which can be bolted, screwed, latched, snap-fitted, magnetically matched, and the like.

Taking the rolling groove 24 and the limiting hole 28 shown in Figure 9 arranged on the bottom wall 211 as an example, the rolling groove 24 provides a placement position for the rolling element 3, and the rolling groove 24 is integrally formed on the machine body 2, which saves assembly procedures and improves the assembly efficiency of the whole machine. The limiting hole 28 arranged on the bottom wall 211 can limit the rolling element 3 when it rolls, preventing the rolling element 3 from being dislocated, thereby providing a guarantee for the smooth pushing and pulling of the pot body 1.

[0066] Example 1: Fig. 9 As shown, the machine body 2 includes a base 26 and a cover plate 27 covering the base 26 to form a bottom wall 211 of the cooking cavity 21. The base 26 is provided with a first positioning column 261 protruding toward the cover plate 27, the top of the first positioning column 261 is recessed inward to form the rolling groove 24, and the cover plate 27 is provided with the limiting hole 28. By providing the first positioning column 261 protruding toward the cover plate 27 on the base 26 and the top of the first positioning column 261 is recessed inward to form the rolling groove 24, the structural design is simple, the integrity of the base 26 is improved, so that the structural strength of the base 26 can be improved to a certain extent, and it is helpful to improve the assembly efficiency of the whole machine.

[0067] Example 2: The machine body 2 includes a base 26 and a side frame disposed above the base 26 and cooperating with the base 26 to enclose the cooking cavity 21.
