Description

Technical Field

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

[0002] An air fryer is a cooking device that quickly heats air flow through a heating element and uses a high-power fan to make the heated air flow contact food ingredients, 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 into 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 reaches the surface of the food ingredients from the upper part of the cooking cavity downward. 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.

[0032] In the present application, unless otherwise clearly specified and limited, the terms such as "installation", "connection", "fixation", 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.

[0033] See Figures 1 to 10 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 electronic 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 inner container 103. An insertion opening 101 communicating with the cooking cavity 100 and allowing 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.

[0034] 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 4 shown, the blower assembly 301 is connected to the side of the fryer body 1 away from the insertion opening 101 and communicates with the cooking cavity 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 the side where the insertion opening 101 of the fryer body 1 is located and the side where the blower assembly 301 of the fryer body 1 is located are oppositely arranged. The blower assembly 301 has an air outlet channel 4 extending upward, and an air outlet 400 communicating with the upper part of the cooking cavity 100 is provided on the air outlet channel 4; In addition, the electric heating element 300 is separated from the blower assembly 301, and the electric heating element 300 is connected above the cooking cavity 100 and arranged corresponding to the air outlet 400. The electric heating element 300 is used to heat the air flow blown out from the air outlet 400 and make the heated hot air flow spread downward into the cooking cavity 100.

[0035] Further in this embodiment, the control panel 6 controls the electric heating element 300 to generate heat, the control panel 6 controls the blower assembly 301 to work, the blower assembly 301 generates an air flow, and the air flow blows upward along the air outlet channel 4 through the air outlet 400. When the blown air flow passes through the electric heating element 300, the temperature of the air flow rises to form a hot air flow. The formed hot air flow spreads downward into the cooking cavity 100 and reaches the surface of the food under the action of the air flow of the blower assembly 301. At the same time, the heat in the cooking cavity 100 is sucked away by the blower assembly 301 again. Therefore, a cycle of hot air flow is formed in the cooking cavity 100, so as to perform cyclic heating and baking on the food.

[0036] Further, in this embodiment, the air fryer separates the electric heating element 300 of the heating assembly 3 and the blower assembly 301, that is, the blower assembly 301 is arranged on the side of the fryer body 1 away from the insertion port 101 and communicated with the cooking cavity 100, and the electric heating element 300 is connected above the cooking cavity 100 and arranged corresponding to the air outlet 400 of the air outlet passage 4 of the blower assembly 301. The air flow generated by the blower assembly 301 is blown out from the air outlet 400 of the air outlet passage 4 and is heated and raised in temperature by the electric heating element 300 when passing through the electric heating element 300, and under the action of the air flow, the heated hot air flow is diffused downward into the cooking cavity 100; in this way, the transmission path of the hot air flow to the surface of the food material is shortened, the transmission time of the hot air flow is short and it can quickly reach the surface of the food material, and the energy consumption loss of the hot air flow in the whole transmission path is less; therefore, this air fryer can reduce the energy consumption during the heat transmission process, making the baking efficiency high and the taste of the food material good.

[0037] Exemplarily, in the related art, the blower assembly conveys the hot air flow generated by the electric heating element to the upper part of the cooking cavity through the air outlet passage, and then diffuses downward from the upper part of the cooking cavity into the cooking cavity; while in this embodiment, the hot air flow generated by the electric heating element 300 under the action of the air flow of the blower assembly 301 directly diffuses downward into the cooking cavity 100 without passing through the air outlet passage 4, so as to reach the surface of the food material to bake the food material; therefore, compared with the air fryer in the related art, the length of the transmission path of the hot air flow generated by the electric heating element 300 to reach the surface of the food material in the cooking cavity 100 is shortened by at least half, and the transmission time of the hot air flow is saved by at least half.

[0038] It is not difficult to understand that the electric heating element 300 is an electric heating wire or an electric heating tube, which is electrically connected to the electronic control unit of the air fryer, generates heat in the energized state, and can quickly increase the temperature and form a hot air flow under the action of the air flow when the air flow passes through the electric heating element 300.

[0039] In this embodiment, the blower assembly 301 includes a motor 302 connected to the fryer body 1 and a wind blade 303 arranged 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, and a wire mesh cover 305 covering the through hole 304 is connected to the inner wall of the cooking cavity 100. Specifically, the air outlet passage 4 is located between the motor 302 and the cooking cavity 100, and the air outlet passage 4 includes a first plate member and a second plate member arranged vertically, such as Figure 4As shown in the figure, 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 channel 4. The air blade 303 of the fan assembly 301 is located in the air outlet channel 4, and the second plate member is provided with a through hole 304 communicating with the cooking cavity 100. The air or hot air flow in the cooking cavity 100 is sucked into the air outlet channel 4 under the action of the rotation of the air blade 303, and is blown out upward along the air outlet channel 4 through the air outlet 400 under the action of the air blade 303. It is not difficult to understand that the lower end of the air outlet channel 4 is a closed end to ensure that the air flow in the air outlet channel 4 can flow upward quickly and improve the baking efficiency.

[0040] Further, in this embodiment, the air blade 303 of the fan assembly 301 is an axial flow air blade 303, and the center of the air blade 303 is aligned with the through hole 304 on the side wall of the air outlet channel 4. It is not difficult to understand that the back of the inner liner 103 of the air fryer is provided with a hole adapted to the through hole 304 on the air outlet channel 4, or the through hole 304 on the air outlet channel 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. The wire mesh cover 305 covering the through hole 304 can prevent food ingredients from entering the fan assembly 301.

[0041] Exemplarily, as Figure 4 and Figure 10 shown in the figure, the air blade 303 includes two annular plates 306 spaced apart along the axial direction, and a plurality of arc-shaped blades 307 are connected between the two annular plates 306. The central hole of the annular plate close to the cooking cavity is coaxial with the through hole 304, and the central hole of the annular plate far from the cooking cavity is connected to the rotating shaft of the motor 302. The air blade 303 has a larger air outlet volume and stronger wind force than the existing technology fan at the same rotation speed, so as to improve the air flow rate and flow velocity and enhance the baking efficiency.

[0042] 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; the top of the food basket is provided with outward flanges on both sides, and a set of slots extending along the depth direction of the cooking cavity 100 are provided on the 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. The back of the food basket is provided with a plurality of ventilation holes, and the plurality of ventilation holes are arranged at a position close to the lower part of the back of the food basket, so that the heat can pass through the food ingredients, making the food ingredients at the bottom of the food basket easier to cook and improving the baking efficiency.

[0043] It is easy to understand that the fan assembly 301 is installed on the back of the fryer body 1, and the airflow generated by the fan assembly 301 is blown to the top of the cooking cavity 100 through the air outlet channel 4 and the air outlet 400. Above the cooking cavity 100, the area closer to the fan assembly 301 has a greater wind pressure and a faster wind speed, while the area farther away from the fan assembly 301 has a relatively smaller wind pressure and a relatively lower wind speed. In this way, the hot air flow heated by the electric heating unit has uneven heat or heat energy in the front and back of the cooking cavity 100, thereby affecting the baking effect and baking efficiency of the food. For this reason, in this embodiment, if Figure 2 、 Figure 3 and Figure 4 As shown, a deflector 5 connected to the cooking cavity 100 is connected above each cooking cavity 100. The deflector 5 extends from the inside to the outside along the depth direction of the cooking cavity 100, and the inner end of the deflector 5 is connected to the air outlet 400, and the electric heating element 300 is arranged in the deflector 5. The deflector 5 is an independent flat component independent of the cooking cavity 100. It is arranged above the cooking cavity 100 and can quickly gather the airflow generated by the fan assembly 301, increase the overall air pressure of the airflow, and enable the electric heating element 300 to quickly heat the airflow gathered in the deflector 5, thereby improving the heating efficiency of the airflow, and enable the hot airflow diffused downward in the deflector 5 to reach the surface of the food quickly and evenly, thereby improving the baking efficiency.

[0044] The inner end of the air guide 5 forms an air inlet 500 connected to the air outlet 400. It is easy to understand that the air outlet 400 blows the airflow from the air inlet 500 of the air guide 5. Under the action of air pressure, the airflow will be concentrated and blown into the air guide 5 quickly, which will cause the electric heating element 300 to heat the airflow unevenly, thereby making the temperature of the hot air entering the cooking cavity 100 uneven, affecting the baking effect. For this reason, in this embodiment, if Figure 2 、 Figure 4 and Figure 5 As shown, a diverter plate 505 is connected to the air inlet 500. The diverter plate 505 is used to disperse the airflow entering the air inlet 500 into the air guide 5. The arrangement of the diverter plate 505 can disperse the concentrated airflow entering the air inlet 500 into multiple airflows and guide them into the air guide 5, so that the airflow can evenly and fully contact the electric heating element 300. This not only improves the heating efficiency of the airflow, but also makes the temperature of the hot air entering the cooking cavity 100 uniform, achieving a good baking effect and preventing partial burning of the food.

[0045] For example, Figure 5 、 Figure 7 and Figure 8As shown, the flow splitter plate 505 is a single piece of plate bent into a wavy shape and arranged along the width direction of the air inlet 500. A flow guiding channel 506 for air flow to be introduced into the flow guiding cover 5 is formed between two adjacent bent portions of the flow splitter plate 505. Compared with the flow guiding grille formed by punching in the prior art, the flow splitter plate 505 can form more flow guiding channels 506, so that the air flow is dispersed into more small air flows, and the air flow can fully contact the electric heating element 300.

[0046] In other embodiments, the flow splitter plate 505 can also adopt other structures, such as a plurality of spaced-apart flow guiding fins vertically connected at the air inlet 500, and a flow guiding channel is formed between adjacent flow guiding fins.

[0047] It is not difficult to understand that in this embodiment, the electric heating element 300 is horizontally arranged in the flow guiding cover 5, and the air inlet 500 is located on one side of the electric heating element 300. Moreover, in the flow guiding cover 5, the closer to the air inlet 500, the faster the air flow speed and the higher the air pressure; the farther away from the air inlet 500, the slower the air flow speed and the lower the air pressure. Therefore, when the electric heating element 300 generates heat, the area close to the air inlet 500 dissipates heat quickly, while the area far from the air inlet 500 dissipates heat slowly, which results in uneven heat dissipation of the electric heating element 300 and uneven front and rear temperatures of the hot air flow entering the cooking cavity. For this reason, in this embodiment, as Figure 7 、 Figure 8 and Figure 9 shown, a heat dissipation plate 507 is connected to the electric heating element 300 and fits against the top of the electric heating element 300, and the heat dissipation plate 507 is connected to the side of the electric heating element 300 close to the air inlet 500. In other words, the heat dissipation plate 507 may not completely cover the electric heating element 300, but only cover the side of the electric heating element 300 close to the air inlet 500, so that the side of the electric heating element 300 away from the air inlet 500 is exposed from the heat dissipation plate 507. The setting of the heat dissipation plate 507 enables the heat of the electric heating element 300 to be quickly transferred to the heat dissipation plate 507, thereby accelerating the heat dissipation of the electric heating element 300, making the overall heat dissipation of the electric heating element 300 uniform, that is, avoiding the defects of concentrated heat and slow heat dissipation speed of the electric heating element 300 and improving the baking efficiency.

[0048] Exemplarily, as Figure 7 shown, the shape of the heat dissipation plate 507 is adapted to the shape inside the flow guiding cover 5, and it is connected to the side of the electric heating element 300 close to the air inlet 500 by screws, and a plurality of heat dissipation holes are evenly distributed on the heat dissipation plate 507.

[0049] Further, in the present embodiment, a baffle 503 extending downward is circumferentially connected to the air deflector 5. Both ends of the baffle 503 are respectively connected to both sides of the air inlet 500, so that the baffle 503 forms a diversion cavity corresponding to the air inlet 500 around the air deflector 5. The electric heating element 300 and the heat dissipation plate 507 are both arranged in the diversion cavity. Specifically, the air deflector 5 includes a top plate 501 and a bottom plate 502 connected to the top of the top plate 501 or the bottom of the top plate 501. The baffle 503 is connected to the bottom plate 502, and the air inlet 500 is arranged on the bottom plate 502; as ​ 、 ​ and ​ shown, the end of the baffle 503 away from the fan assembly 301 is set as a closed end, and the closed end is arc-shaped. In this way, the air flow blown out from the air outlet 400 of the air outlet passage 4 first enters the air deflector 5 instead of directly entering the cooking cavity 100. While the air flow accumulates in the air deflector 5, its temperature rises under the heating of the electric heating element 300. The generated hot air flow is evenly diffused into the cooking cavity 100 from top to bottom under the action of the fan assembly 301, thus effectively avoiding the defects that the front and rear flow velocities or air pressures of the hot air flow entering the cooking cavity 100 are inconsistent, resulting in uneven cooking of ingredients, long baking time and poor taste. In addition, by setting the closed end of the baffle 503 to be arc-shaped, after the air flow at the air outlet 400 enters the diversion cavity of the air deflector 5, a vortex or swirl will be generated in the diversion cavity of the hot air flow, and its air flow can fully contact and heat the electric heating element 300, and the air pressure increases to improve the downward diffusion speed of the hot air flow.

[0050] Further, in the present embodiment, as ​ and ​ shown, a wind shield 504 extending downward and bent is provided on one side of the bottom plate 502 close to the insertion port 101. The setting of the wind shield 504 serves to gather heat and prevent the hot air flow from blowing towards the insertion port 101, so that the hot air flow can quickly move downward to reach the surface of the ingredients.

[0051] In order to enable the air flow blown out from the air outlet 400 of the air outlet passage 4 to quickly reach the inside of the air deflector 5, as ​ and ​ shown, the inner end of the air deflector 5 or the air inlet 500 of the air deflector is set to be wider outside and narrower inside, so that the air flow blown out from the air outlet 400 can quickly enter the air deflector 5.

[0052] Refer to again ​As shown, 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 openings 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 located on the back of the cooking chamber 100 and an electric heating element 300 located at the top or above the cooking chamber 100. In this embodiment of the 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 divides the inner container 103 into two independent cooking chambers 100, so that the ingredients in the two cooking chambers 100 will not have flavor cross-talk.

[0053] In other embodiments, the cooking chamber 100 can also be three, four, etc., and 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, so that the fryer body 1 is a single-layer multi-chamber structure. That is to say, in other embodiments, the 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, 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.

[0054] In some embodiments, such as ​ and ​ As shown, a groove 102 is provided on the outer shell 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. That is to say, the control panel 6 can be rotated and extended out of the groove 102 during use, and can be retracted or folded into the groove 102 when not in use. Such a setting is convenient for users to operate at different use angles, and further saves the space inside the outer shell.
