Description

Technical Field

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

[0002] An air fryer is a cooking device that quickly heats air flow through a heating element and makes the heated air flow contact food ingredients through a high-power fan, so as to achieve the frying effect for the food ingredients. Because the food ingredients made by it have a good taste, less oil and fewer harmful substances, it is deeply loved by people. Therefore, it has gradually been accepted by ordinary families and brought convenience to people's lives.

[0003] In related art air fryers, there are single-pot air fryers and double-pot air fryers. The single-pot air fryer has a set of heating components, while the double-pot air fryer, especially the double-pot air fryer with upper and lower layers, generally has two sets of heating components; each set of heating components includes an electric heating element and a fan. The electric heating element is generally an electric heating wire or an electric heating tube, and the fan blows the heat generated by the electric heating element to the inner container or the food cooking cavity to bake the food. In related art air fryers, especially double-pot air fryers, in order to expand the space of the cooking cavity, the heating components are generally arranged on the back of the air fryer or on the side far from the user. The hot air blown by the fan is diffused into the cooking cavity through the air outlet channel. Specifically, the air outlet channel is vertically arranged on the back of the cooking cavity, and the upper end of the air outlet channel is connected to the top of the cooking cavity. The fan blows the hot air flow generated around the heating element upward through the air outlet channel to the top of the cooking cavity, and the hot air flow then diffuses downward from the top of the cooking cavity to bake the food in the cooking cavity, such as the double-pot air fryer disclosed in the patent application with the publication number CN117562428A.

[0004] The related art air fryer has the following defects in the actual use process: both the electric heating element and the fan of the heating component are arranged on the back of the cooking cavity or on the side of the air fryer far from the user. The fan blows the hot air flow generated by the electric heating element upward through the air outlet channel to the upper part of the cooking cavity, and then downward from the upper part of the cooking cavity to the surface of the food ingredients. This results in a longer transmission time of the hot air flow and more energy loss; that is, the time taken for the hot air flow to reach the surface of the food ingredients from generation is longer, the heat transfer path is farther, and the heat loss is higher; therefore, the baking efficiency of the related art air fryer is lower, and the taste of the baked food ingredients is poorer.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0036] In the present application, unless otherwise clearly specified and defined, terms such as "install", "connect", "fix", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0037] See Figures 1 to 11 As shown, an embodiment of the present application discloses an air fryer, the structure of which includes a fryer body 1 and a fry basket 2. The fryer body 1 includes a housing, an electric control unit connected to the housing, a control panel 6, and an inner container 103 connected inside the housing. The fryer body 1 has at least one cooking cavity 100, and the cooking cavity 100 is formed in the space defined by the inner container 103. An insertion opening 101 that is connected to the cooking cavity 100 and allows the fry basket 2 to be inserted into or removed from the cooking cavity 100 is provided on the user side of the fryer body 1, and the number of the insertion openings 101 is adapted to the number of the cooking cavities 100; at least one heating component 3 corresponding to the cooking cavity 100 is connected inside the fryer body 1, that is, one cooking cavity 100 corresponds to one heating component 3.

[0038] In this embodiment, each heating component 3 includes an electric heating element 300 and a blower assembly 301, as Figure 2 、 Figure 3 and Figure 4As shown, the blower assembly 301 is connected to the side of the fryer body 1 away from the insertion port 101 and communicates with the cooking chamber 100, that is, the blower assembly 301 is connected to the back of the fryer body 1, or connected to the side away from the user side, or disposed on the opposite side of the side where the insertion port 101 of the fryer body 1 is located. The blower assembly 301 has an air outlet passage 4 extending upward, and an air outlet 400 communicating with the upper part of the cooking chamber 100 is provided on the air outlet passage 4; the electric heating element 300 is an electric heating wire or an electric heating tube, and is arranged in a planar bent shape or a planar spiral shape. The electric heating element 300 is arranged between the blower assembly 301 and the cooking chamber 100. Correspondingly, a through hole 304 for communicating the cooking chamber 100 with the electric heating element 300 is provided on the side wall of the inner liner 103 of the cooking chamber 100 close to the electric heating element 300, so that the air flow in the cooking chamber 100 can enter the electric heating element 300 and the blower assembly 301 through the through hole 304. The blower assembly 301 forms a hot air flow with the heat generated by the electric heating element 300 and blows the hot air flow through the air outlet passage 4 and out of the air outlet 400 to the upper part of the cooking chamber 100. After the hot air flow above the cooking chamber 100 reaches the surface of the food material downward, it enters the heating assembly 3 through the through hole 304 again. Therefore, the cooking chamber 100, the heating assembly 3, the air outlet passage 4, the air outlet 400 and the cooking chamber 100 form a hot air flow circulation path, so as to perform cyclic heating and baking on the food material.

[0039] Exemplarily, as Figure 2 and Figure 4 shown, the electronic control unit controls the electric heating element 300 to generate heat, and the electronic control unit controls the blower assembly 301 to work. The blower assembly 301 forms a hot air flow with the heat around the electric heating element 300, and makes the hot air flow blow upward along the air outlet passage 4 and out of the air outlet 400 to the upper part of the cooking chamber 100. The hot air flow above the cooking chamber 100 diffuses downward into the cooking chamber 100 and reaches the surface of the food material under the action of the air flow of the blower assembly 301. At the same time, the heat in the cooking chamber 100 is sucked away by the blower assembly 301 again. Therefore, a cycle of hot air flow is formed in the cooking chamber 100, so as to perform cyclic heating and baking on the food material.

[0040] It is not difficult to understand that in the air flow transmission path where the heat generated by the electric heating element 300 passes through the air outlet passage 4 and is blown out of the air outlet 400, the heat or energy loss of the hot air flow is bound to occur, so that the heat of the hot air flow reaching the upper part of the cooking chamber 100 is insufficient or does not meet the technical requirements for quickly baking food materials. For this reason, in this embodiment, as Figure 2 and Figure 4 shown, the air fryer further includes at least one compensation heat source 7. Specifically, a compensation heat source 7 is connected above the cooking chamber 100, and the compensation heat source 7 is arranged corresponding to the air outlet 400, and is used for heating the air flow blown out of the air outlet 400 to compensate for the heat loss of the air flow.

[0041] That is, in this embodiment, the blower assembly 301 of the air fryer forms a hot air flow with the heat generated by the electric heating element 300 and blows it out through the air outlet 400 of the air outlet passage 4. During the transmission of the hot air flow in the air outlet passage 4, certain heat loss is bound to occur. However, in the air fryer of the present application, a compensation heat source 7 is provided at a position above the cooking cavity 100 and corresponding to the air outlet 400. The compensation heat source 7 can heat the air flow blown out from the air outlet 400 to compensate for the heat loss of the air flow, so that the heat or energy of the hot air flow reaching above the cooking cavity 100 is higher, and the hot air flow above the cooking cavity 100 can quickly bake the food when reaching the surface of the food, improving the baking efficiency and the taste of the food. Therefore, the air fryer can compensate for the energy consumption during the heat transmission process, improve the baking efficiency and the taste of the food.

[0042] The compensation heat source 7 is connected above the cooking cavity 100 and is arranged corresponding to the air outlet 400; therefore, the compensation heat source 7 can be connected to the top wall of the cooking cavity 100, or the compensation heat source 7 is connected at or inside the air outlet 400; specifically, in this embodiment, as Figure 4 shown, the compensation heat source 7 is connected to the top of the cooking cavity 100 and is located on one side close to the air outlet 400, so that the air flow blown out from the air outlet 400 can directly contact the compensation heat source 7, thereby increasing the temperature of the air flow.

[0043] In this embodiment, the compensation heat source 7 is an electric heating tube, specifically bent in a U shape or a square shape. In other embodiments, it can also be an electric heating wire. When the air flow passes through, the passing air flow is heated and raised in temperature.

[0044] Further, in this embodiment, as Figure 4 shown, the blower assembly 301 includes a motor 302 connected to the fryer body 1 and a blower blade 303 disposed in the air outlet passage 4 and connected to the rotating shaft of the motor 302. A through hole 304 communicating with the cooking cavity 100 is provided on the side wall of the air outlet passage 4 close to the cooking cavity 100. The electric heating element 300 is disposed in the air outlet passage 4 and is disposed opposite to the blower assembly 301; specifically, the air outlet passage 4 includes a vertically disposed first plate member and a second plate member. The second plate member is located on the side close to the cooking cavity 100, and the space between the first plate member and the second plate member forms an upwardly extending air outlet passage 4. The blower blade 303 of the blower assembly 301 and the electric heating element 300 are both located in the air outlet passage 4, and a through hole 304 communicating with the cooking cavity 100 is provided on the second plate member; the air or hot air flow in the cooking cavity 100 is sucked into the air outlet passage 4 under the action of the rotation of the blower blade 303 and is blown out upward through the air outlet 400 under the action of the blower blade 303. It is not difficult to understand that the lower end of the air outlet passage 4 is a closed end to ensure that the air flow in the air outlet passage 4 can flow upward quickly, improving the baking efficiency.

[0045] Further, in this embodiment, the wind blades 303 of the fan assembly 301 are composed of at least two wind wheels 307 distributed along the axial direction. As Figure 6 shown, the two wind wheels 307 are distributed along the axial direction and are respectively connected to the rotating shaft of the motor 302. At the same rotation speed, the wind blades 303 have a larger air output and stronger wind force compared to the prior art fans, thereby increasing the air flow rate and flow velocity, and improving the baking efficiency.

[0046] In other embodiments, as Figure 7 shown, the wind blades 303 of the fan assembly 301 can also be axial flow wind blades 303, and the center of the wind blades 303 is aligned with the through hole 304 on the side wall of the air outlet passage 4. It is not difficult to understand that a hole adapted to the through hole 304 on the air outlet passage 4 is provided on the back of the inner liner 103 of the air fryer, or the through hole 304 on the air outlet passage 4 and the hole on the back of the inner liner 103 of the air fryer are the same hole or share a through hole 304. A mesh cover can be provided on the through hole 304 to prevent food ingredients from entering the fan assembly 301.

[0047] Exemplarily, as Figure 7 shown, the wind blades 303 include two annular plates 305 spaced apart along the axial direction, and a plurality of arc-shaped blades 306 are connected between the two annular plates 305. The central hole of the annular plate 305 close to the cooking cavity 100 is coaxial with the through hole 304, and the central hole of the annular plate 305 far from the cooking cavity 100 is connected to the rotating shaft of the motor 302. At the same rotation speed, the wind blades 303 have a larger air output and stronger wind force compared to the prior art fans, thereby increasing the air flow rate and flow velocity, and improving the baking efficiency.

[0048] It can be understood that the frying basket 2 of this embodiment includes a panel connected to the insertion port 101, a food basket for holding food ingredients connected to the inner side of the panel, and a handle installed on the outer side wall of the panel. A transparent window can be connected to the panel; flanges extending outward are provided on both sides of the top of the food basket, and a set of slots extending along the depth direction of the cooking cavity 100 are provided on two opposite inner side walls of each cooking cavity 100. The flanges on both sides of the frying basket 2 can be slidably inserted into the set of slots; a plurality of ventilation holes 200 are provided on the back of the food basket, and the plurality of ventilation holes 200 are arranged at a position close to the lower part of the back of the food basket. As Figure 11 shown, this allows heat to pass through the food ingredients, making the food ingredients at the bottom of the food basket easier to cook and improving the baking efficiency.

[0049] It is not difficult to understand that the fan assembly 301 is installed on the back of the fryer body 1. The air flow generated by the fan assembly 301 blows to the upper part of the cooking cavity 100 through the air outlet channel 4 and the air outlet 400. In the area above the cooking cavity 100 closer to the fan assembly 301, the air pressure is relatively high and the wind speed is relatively fast, while in the area far from the fan assembly 301, the air pressure is relatively low and the wind speed is relatively slow. In this way, the heat flow heated by the electric heating unit has uneven heat or thermal energy before and after in the cooking cavity 100, thus affecting the baking effect and baking efficiency of the food materials. Therefore, in this embodiment, as Figure 2 、 Figure 3 and Figure 4 shown, a flow guide cover 5 for guiding the air flow downward is connected to the top of the cooking cavity 100, and the flow guide cover 5 has an air inlet 500 communicated with the air outlet 400; the compensation heat source 7 is arranged at the air inlet 500. The hot air flow blown out from the air outlet 400 enters the air inlet 500 of the flow guide cover 5 and contacts the compensation heat source 7 to be heated up, and then enters the flow guide cover 5 under the action of the air flow. Under the downward guiding action of the flow guide cover 5, the hot air flow diffuses downward into the cooking cavity 100. The flow guide cover 5 plays a role in quickly gathering the air flow, can improve the overall air pressure of the air flow, enable the air flow in the flow guide cover 5 to quickly and evenly reach the surface of the food materials downward, and improve the baking efficiency.

[0050] Specifically, in this embodiment, the flow guide cover 5 is connected with baffles 501 extending downward along the circumferential direction. The two ends of the baffles 501 are respectively connected to both sides of the air inlet 500, so that the baffles 501 surround and form a flow guide cavity corresponding to the air inlet 500 on the flow guide cover 5. The end of the baffle 501 far from the air inlet 500 is arranged in an arc shape. The hot air flow at the air inlet 500 enters the flow guide cover 5 and diffuses downward after encountering the baffle 501. Further, because the end of the baffle 501 far from the air inlet 500 is arranged in an arc shape, after the air flow at the air outlet 400 enters the flow guide cover 5 through the air inlet 500, the heated or compensated hot air flow will generate vortex or swirl in the flow guide cover 5. In this way, not only the front and rear temperatures of the air flow in the cooking cavity 100 are consistent, but also the air pressure is increased to improve the downward diffusion speed of the hot air flow, achieving the purpose of rapid baking.

[0051] Furthermore, in this embodiment, as Figure 8 、 Figure 9 and Figure 10As shown, the fairing 5 is connected to the top wall of the cooking cavity 100. A first deflector plate 502 is connected in the flow guiding cavity surrounded by the baffle 501. The first end of the first deflector plate 502 is arranged in the middle of the air inlet 500 and extends towards the air outlet 400. The second end of the first deflector plate 502 extends towards the end of the flow guiding cavity away from the air inlet 500, and is used to divide the flow guiding cavity into a first flow guiding cavity 506 and a second flow guiding cavity 507 which are distributed left and right. The setting of the first deflector plate 502 can divide the air flow entering the air inlet 500 into two parts, avoiding the concentration of the air flow in the flow guiding cavity and the high local temperature.

[0052] In a preferred embodiment, the first end of the first deflector plate 502 is arranged at the central position of the air inlet 500, so that the air flow entering the air inlet 500 is evenly divided into two parts, making the air flow temperature in the flow guiding cavity uniform.

[0053] It is not difficult to understand that the air flow heated by the compensation heat source 7 will quickly gather on the side of the flow guiding cavity away from the air inlet 500 under the action of the air pressure at the air outlet 400. This results in a low temperature on the side of the flow guiding cavity close to the air inlet 500 and a high temperature on the side of the flow guiding cavity away from the air inlet 500, thus making the air flow temperature in the cooking cavity uneven and affecting the baking effect. In this embodiment, as Figure 9 and Figure 10 shown, the first deflector plate 502 is arranged in an arc shape along the air inlet direction of the air inlet 500. Specifically, the second end of the first deflector plate 502 bends towards the second flow guiding cavity 507; A second deflector plate 503 for blocking at least a part of the air flow is connected in the first flow guiding cavity 506. The second deflector plate 503 is arranged transversely along the first flow guiding cavity 506, and the distance from the inner end of the second deflector plate 503 to the air inlet 500 is greater than the distance from the outer end of the second deflector plate 503 to the air inlet 500; A third deflector plate 505 for blocking at least a part of the air flow is connected in the second flow guiding cavity 507. The third deflector plate 505 is arranged transversely along the second flow guiding cavity 507, and the distance from the inner end of the third deflector plate 505 to the air inlet 500 is greater than the distance from the outer end of the third deflector plate 505 to the air inlet 500. With this setting, the second deflector plate 503 and the third deflector plate 505 can block at least a part of the air flow, thereby preventing all the air flow from gathering on the side of the flow guiding cavity away from the air inlet 500, so as to adjust the temperature of the air flow in the flow guiding cavity, making the temperature of the air flow entering the cooking cavity uniform and thus achieving a good baking effect.

[0054] In this embodiment, the heights of the second deflector plate 503 and the third deflector plate 505 are both lower than the height of the first deflector plate 502, so as to block at least a part of the air flow.

[0055] Further in this embodiment, as Figure 8 and Figure 9As shown in the figure, the deflector 5 includes a base plate and a fixing plate connected inside the base plate. The fixing plate is connected to the base plate, and the baffle 501 is connected to the fixing plate. A wind shielding portion 504 extending downward and bent is provided on one side of the base plate close to the insertion port 101. The setting of the wind shielding portion 504 serves to gather heat and prevent the hot air flow from blowing towards the insertion port 101, enabling the hot air flow to quickly move downward to reach the surface of the food ingredients.

[0056] Refer to again Figures 1 to 4 As shown in the figure, in this embodiment, the air fryer is a double-pot air fryer. Specifically, there are two cooking chambers 100, which are sequentially distributed along the height direction of the inner container 103; there are two frying baskets 2, and the two frying baskets 2 are respectively connected to the two cooking chambers 100 through the insertion ports 101; similarly, there are two heating components 3, which are respectively arranged corresponding to the two cooking chambers 100. Each heating component 3 includes a fan component 301 and an electric heating element 300; there are two compensation heat sources 7, and the two compensation heat sources 7 are respectively connected to the tops of the two cooking chambers 100; in the implementation manner of this double-pot air fryer, the deflector 5 located above is connected to the top of the inner container 103, and the deflector 5 located below is connected to the bottom of the intermediate horizontal partition in the middle of the inner container 103. And the deflector 5 located below and the intermediate horizontal partition separate the inner container 103 into two independent cooking chambers 100, so that the food ingredients in the two cooking chambers 100 will not have flavor mixing.

[0057] In other embodiments, the number of cooking chambers 100 can also be three, four, etc., and they are distributed along the height direction of the fryer body 1; similarly, in other embodiments, the cooking chambers 100 can also be sequentially distributed along the width direction of the fryer body 1, making the fryer body 1 a single-layer multi-chamber structure. That is to say, in other embodiments, this air fryer can also be a single-pot air fryer or a three-pot air fryer. As for the single-pot air fryer, it only has one cooking chamber 100, one frying basket 2, one heating component 3, one compensation heat source 7, etc.; and for the three-pot air fryer, the corresponding cooking chambers 100, frying baskets 2, and heating components 3 can also be all set to three, or the heating component 3 can be set to two, etc.

[0058] In some embodiments, such as Figure 1 As shown in the figure, a groove 102 is provided on the outer side wall of the fryer body 1, and a control panel 6 that can be rotated and is movable back and forth is rotatably connected in the groove 102.
