Description

Technical Field

[0001] This utility model relates to the field of cooking appliances technology, specifically to an air fryer. Background Technology

[0002] In related technologies, air fryers typically cook food using hot air. The hot air comes into direct contact with the food to exchange heat, heating the food while also removing moisture from it. Therefore, to cook soups, the soups need to be placed in a relatively enclosed space to avoid direct heat exchange with the hot air, which would cause the liquid to evaporate. This results in low cooking efficiency for soups in air fryers. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose an air fryer that has the advantage of high cooking efficiency for soups.

[0005] The air fryer of this utility model embodiment includes a body, a stewing pot, a heating component, and a hot air component. The body has a accommodating cavity; the stewing pot is adapted to be placed in the accommodating cavity; the heating component is disposed at the bottom of the accommodating cavity for heat exchange contact with the stewing pot; the hot air component is installed on the body and located above the stewing pot for delivering hot air to the accommodating cavity.

[0006] According to the air fryer of this utility model embodiment, the stewing pot can form a relatively sealed space. Therefore, when soup is placed inside, the hot air in the containment cavity exchanges heat with the stewing pot instead of directly exchanging heat with the soup inside, effectively preventing the liquid in the soup from evaporating and affecting the cooking effect. Furthermore, in addition to the convection heating of the stewing pot by the hot air blown out by the hot air assembly, heat conduction heating is also achieved through heat exchange contact between the heating assembly and the stewing pot. The combination of these two heating methods results in a faster temperature rise in the stewing pot and higher cooking efficiency for the soup inside.

[0007] Optionally, the air fryer further includes a pot body with a cooking chamber inside. The pot body is placed within the receiving chamber, and the stewing pot is placed within the cooking chamber. By incorporating a pot body, this air fryer effectively prevents grease from the stewing pot from adhering to the inner wall of the receiving chamber and increasing cleaning difficulty when the stewing pot boils. Furthermore, the stewing pot can be removed, and the pot body can support solid foods, effectively enabling the air fryer to bake and fry solid foods, thus enhancing its functionality.

[0008] Optionally, at least one of the heating component and the hot air component includes a heating element that radiates far-infrared rays into the cooking cavity during operation. In this air fryer, the heating element of at least one of the heating component and the hot air component radiates far-infrared rays into the stew pot to achieve thermal radiation heating of the stew pot. The combination of these three heating methods further improves the cooking efficiency of soups and other soups in the stew pot.

[0009] Optionally, at least a portion of the stewing pot includes a light-transmitting element through which far-infrared rays pass. In this air fryer, the far-infrared rays radiated by the heating element of at least one of the heating components and the hot air component directly pass through the light-transmitting element and act on the soup, achieving direct heating of the soup and further improving the cooking efficiency of the soup.

[0010] Optionally, the stewing pot includes a pot body and a lid. The pot body has a stewing cavity and an open top. The lid is connected to the pot body and seals the open top. At least one of the pot body and the lid is a light-transmitting element. This invention, by designing at least one of the pot body and the lid as a light-transmitting element, reduces the manufacturing difficulty of the pot body and / or lid, and effectively ensures that the stewing pot has a sufficiently large light-transmitting area, thereby effectively ensuring the heating efficiency of the far-infrared rays radiated by the heating element on the food in the stewing cavity.

[0011] Optionally, the lid is a light-transmitting element, and the hot air assembly includes a first heating element that radiates far-infrared rays to the lid when heating. This air fryer, by setting the lid to be a light-transmitting element, facilitates observation of the state of soup or similar food inside the cooking chamber through the lid, and also allows the first heating element to directly radiate far-infrared rays to the food inside the cooking chamber through the lid, effectively improving the cooking efficiency of the food inside the cooking chamber.

[0012] Optionally, the stewing pot includes a pot body and a lid, wherein the pot body is made of stainless steel, ceramic, or glass, and the lid is made of stainless steel, ceramic, or glass. This invention, by using either the pot body or the lid made of high-efficiency heat transfer materials such as stainless steel, ceramic, or glass, effectively improves the heat convection heating efficiency of the hot air assembly and the heat conduction heating efficiency of the heating assembly, resulting in higher cooking efficiency for food within the stewing chamber.

[0013] Optionally, the lid of the pot has a middle cavity, the lower wall of the middle cavity is provided with a first vent hole communicating with the stewing cavity, and the upper wall of the middle cavity is provided with a second vent hole communicating with the cooking cavity;

[0014] A sealing ball is rolled within the intermediate cavity. Under gravity, the sealing ball seals the first vent hole. The sealing ball is also able to avoid the first vent hole due to the movement of steam within the cooking chamber. This air fryer, by using a sealing ball to seal the first vent hole under its own weight, prevents steam from escaping from the cooking chamber. This allows the air pressure within the cooking chamber to continuously increase, thereby raising the boiling point of the water and increasing the heat capacity, resulting in more efficient cooking of soups and similar foods. Furthermore, when the air pressure within the cooking chamber reaches a set value, the steam pushes the sealing ball away from the first vent hole, allowing steam to escape through the first vent hole, the intermediate cavity, and the second vent hole into the cooking chamber. This effectively prevents excessive pressure within the cooking chamber from reducing safety.

[0015] Optionally, the lid of the stewing pot has a spice placement cavity, and the lower wall of the lid is provided with a vent hole connecting the spice placement cavity and the stewing cavity. In this air fryer, when heating the stewing pot, the aroma molecules volatilized from the spices in the spice placement cavity only enter the stewing cavity through the vent hole, effectively preventing aroma molecules from leaking out. This facilitates high-intensity, long-term contact between the aroma molecules and the soup-like food in the stewing cavity, thereby enhancing the aroma-enhancing effect.

[0016] Optionally, the air fryer further includes a mounting bracket adapted to be placed inside the cooking cavity. The mounting bracket has at least two first positioning slots for engaging with the stewing pot. The at least two first positioning slots are interconnected and define a second positioning slot for engaging with the stewing pot at the connection point. The second positioning slot is located at the center of the mounting bracket. With this invention, when at least two stewing pots are used, each pot can be engaged in one of the at least two first positioning slots. This ensures high stability of the stewing pots within the cooking cavity, preventing them from shifting and leaking soup. Simultaneously, when only one stewing pot is used, it engages in the second positioning slot. In this case, the stewing pot is located at the center of the mounting bracket, resulting in more even heating and higher cooking efficiency for soups within the cooking cavity.

Detailed Implementation

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is combined Figures 1-7 This invention describes an air fryer according to an embodiment of the present invention.

[0028] The air fryer of this embodiment includes a body 1, a stewing pot 2, a heating element 3, and a hot air element 4. The body 1 has a receiving cavity, and the stewing pot 2 is suitable for being placed in the receiving cavity. The heating element 3 is located at the bottom of the receiving cavity for heat exchange with the stewing pot 2. The hot air element 4 is installed on the body 1 and located above the stewing pot 2 for delivering hot air into the receiving cavity.

[0029] According to the air fryer of this embodiment, the stewing pot 2 can form a relatively sealed space. Therefore, when soup is placed inside, the hot air in the containment cavity exchanges heat with the stewing pot 2 instead of directly exchanging heat with the soup inside, effectively preventing the liquid in the soup from evaporating and affecting the cooking effect. Furthermore, in addition to the convection heating of the stewing pot 2 by the hot air blown out by the hot air assembly 4, heat conduction heating of the stewing pot 2 is also achieved through heat exchange contact between the heating assembly 3 and the stewing pot 2. The combination of these two heating methods results in a faster temperature rise in the stewing pot 2, leading to higher cooking efficiency for the soup inside.

[0030] It should be noted that, such as Figure 1As shown, the hot air assembly 4 includes a motor, a fan, and a first heating element arranged sequentially from top to bottom, with the motor connected to the fan. The heating assembly 3 includes a second heating element and a heating plate abutting above the second heating element, with the heating plate in heat exchange contact with the stew pot 2.

[0031] In some embodiments, the air fryer also includes a pot body 5, which has a cooking cavity 51. The pot body 5 is placed in the receiving cavity, and the stewing pot 2 is placed in the cooking cavity 51.

[0032] By setting the pot body 5, on the one hand, it effectively prevents the grease from the stewing pot 2 from boiling and adhering to the inner wall of the container cavity, thus increasing the difficulty of cleaning. On the other hand, the stewing pot 2 can also be removed, and the pot body 5 can support solid foods, effectively realizing the baking and air-frying functions of the air fryer for solid foods, making the air fryer more functional.

[0033] For example, such as Figure 1 As shown, the pot body 5 is detachably disposed in the accommodating cavity, and the stewing pot 2 is detachably disposed in the cooking cavity 51 of the pot body 5. The heating plate of the heating component 3 abuts against the bottom wall of the pot body 5 to achieve heat conduction heating of the stewing pot 2.

[0034] In some embodiments, at least one of the heating component 3 and the hot air component 4 includes a heating element that radiates far-infrared rays into the cooking cavity 51 during operation.

[0035] The heating element of at least one of the heating components 3 and the hot air component 4 radiates far-infrared rays to the stew pot 2 to achieve heat radiation heating of the stew pot 2. The combination of the three heating methods further improves the cooking efficiency of soups in the stew pot 2.

[0036] For example, the heating element is a carbon fiber heating element, a silicon carbide heating element, a far-infrared ceramic heating element, or a metal oxide heating element.

[0037] In some embodiments, at least a portion of the stew pot 2 includes a light-transmitting element through which far-infrared rays pass.

[0038] The far-infrared rays radiated by the heating element of at least one of the heating components 3 and hot air components 4 directly pass through the light-transmitting element and act on the soup, thereby achieving direct heating of the soup and further improving the cooking efficiency of the soup.

[0039] For example, the entire stew pot 2 is made of transparent material, or the body 21 or lid 22 of the stew pot 2 is made of transparent material.

[0040] In some embodiments, the stewing pot 2 includes a pot body 21 and a pot lid 22. The pot body 21 has a stewing cavity 211 and an open top. The pot lid 22 is connected to the pot body 21 and seals the open top. At least one of the pot body 21 and the pot lid 22 is a light-transmitting element.

[0041] By setting at least one of the body 21 and the lid 22 as a light-transmitting element, the manufacturing difficulty of the body 21 and / or the lid 22 is reduced, and the stewing pot 2 is effectively guaranteed to have a sufficiently large light-transmitting area, thereby effectively ensuring the heating efficiency of the far-infrared rays radiated by the heating element on the food in the stewing cavity 211.

[0042] Optionally, the lid 22 is a light-transmitting component, and the hot air assembly 4 includes a first heating element 41, which radiates far-infrared rays to the lid 22 when heating.

[0043] By setting the lid 22 as a light-transmitting element, it is convenient to observe the state of the soup in the stewing cavity 211 through the lid 22, and it is also convenient for the first heating element 41 to radiate far-infrared rays directly to the food in the stewing cavity 211 through the lid 22, which effectively improves the cooking efficiency of the food in the stewing cavity 211.

[0044] For example, the lid 22 is made of glass, and the first heating element 41 is a carbon fiber heating element, a silicon carbide heating element, a far-infrared ceramic heating element, or a metal oxide heating element.

[0045] In some embodiments, the stewing pot 2 includes a pot body 21 and a pot lid 22, wherein the pot body 21 is made of stainless steel, ceramic or glass, and the pot lid 22 is made of stainless steel, ceramic or glass.

[0046] By setting either the body 21 or the lid 22 to be made of stainless steel, ceramic or glass with high heat transfer efficiency, the heat convection heating efficiency of the hot air assembly 4 and the heat conduction heating efficiency of the heating assembly 3 are effectively improved, making the air fryer more efficient at cooking food in the stewing chamber 211.

[0047] For example, the body 21 is made of ceramic, and the lid 22 is made of glass.

[0048] For example, both the body 21 and the lid 22 are made of glass.

[0049] For example, both the body 21 and the lid 22 are made of ceramic.

[0050] In some embodiments, the lid 22 has a central cavity 221. The lower wall of the central cavity 221 is provided with a first vent 222 communicating with the stewing cavity 211, and the upper wall of the central cavity 221 is provided with a second vent communicating with the cooking cavity 51. A sealing ball 23 is rolled inside the central cavity 221. The sealing ball 23 seals the first vent 222 under the action of gravity. The sealing ball 23 can avoid the first vent 222 under the push of the steam in the stewing cavity 211.

[0051] By setting the sealing ball 23 to seal the first vent 222 under its own weight, the steam in the stewing chamber 211 is prevented from escaping, allowing the air pressure inside the stewing chamber 211 to continuously increase. This, in turn, causes the boiling point of the water inside to continuously increase, resulting in a greater degree of heating and higher cooking efficiency for soups and other foods. Moreover, when the air pressure inside the stewing chamber 211 increases to a set value, the steam can push the sealing ball 23 away from the first vent 222, allowing the steam to escape through the first vent 222, the intermediate cavity 221, and the second vent into the cooking chamber 51. This effectively prevents excessive pressure inside the stewing chamber 211 from reducing safety.

[0052] For example, such as Figure 2 and Figure 3 As shown, the lower wall of the intermediate cavity 221 is a downwardly concave first arc surface, and the upper wall is an upwardly convex second arc surface. A first vent hole 222 is provided at the lowest point of the first arc surface. The diameter of the first vent hole 222 is smaller than the diameter of the sealing ball 23. The maximum vertical distance between the first and second arc surfaces is greater than the diameter of the sealing ball 23. Guided by the arc surface, the sealing ball 23 automatically slides into the first vent hole 222 to seal it. The number of second vent holes can be multiple and is directly smaller than the diameter of the first vent hole 222.

[0053] It should be noted that the lid 22 can be directly fastened to the body 21, or the lid 22 can be snapped into the body 21.

[0054] In some embodiments, such as Figure 4 As shown, the lid 22 has a spice placement cavity 223, and the lower wall of the lid 22 is provided with a vent hole that connects the spice placement cavity 223 and the stewing cavity 211.

[0055] When the stewing pot 2 is heated, the aroma molecules of the spices in the spice placement cavity 223 enter the stewing cavity 211 only through the vent, effectively preventing the aroma molecules from leaking out. This allows the aroma molecules to have high-intensity and long-term contact with the soup food in the stewing cavity 211, thereby increasing the aroma-enhancing effect.

[0056] For example, the number of vent holes is preferably multiple, and the vent holes are micropores, which facilitates the evaporation of aroma molecules into the stewing chamber 211 while preventing the spices from falling directly into the stewing chamber 211.

[0057] It should be noted that the spice compartment 223 can hold tea, sugar or coarse salt to achieve tea smoking, sugar smoking and salt baking cooking processes respectively.

[0058] In some embodiments, the air fryer further includes a mounting bracket 6 adapted to be placed inside the cooking cavity 51. The mounting bracket 6 has at least two first positioning grooves 61 for engaging with the stewing pot 2. The at least two first positioning grooves 61 are connected to each other and define a second positioning groove 62 for engaging with the stewing pot 2 at the connection point. The second positioning groove 62 is located at the center of the mounting bracket 6.

[0059] By setting the mounting bracket 6, when there are at least two stewing pots 2, each stewing pot 2 can be fitted into at least two first positioning slots 61. The stewing pots 2 are reliably fixed in the cooking cavity 51, and are not easy to shake, which would cause soup to leak out. At the same time, when there is only one stewing pot 2, the stewing pot 2 is fitted into the second positioning slot 62. At this time, the stewing pot 2 is located in the center of the mounting bracket 6, which results in more uniform heating and higher cooking efficiency of soup in the stewing cavity 211 by the air fryer.

[0060] For example, such as Figures 5-7 As shown, there are three first positioning grooves 61, which are connected to each other and form a second positioning groove 62 at the connection point. Both the first positioning groove 61 and the second positioning groove 62 are round holes for the cup body 21 to fit.
