Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and more particularly to an air fryer. Background Technology

[0002] An air fryer is a machine that uses air to "fry" food. It primarily uses hot air instead of the hot oil in a frying pan to cook the food. The hot air also removes surface moisture, achieving a similar effect to deep-frying. Current air fryers generally have a "drawer" structure, consisting of a main body and an inner liner. A heating element and fan are located at the top of the main body to blow hot air into the inner liner to heat the food. Currently, some air fryers blow hot air directly onto the top of the food, and a few achieve circulating hot air within the inner liner. However, most air fryers do not have good airflow guidance and distribution, resulting in uneven heating of the food on the top and bottom, requiring manual turning.

[0003] In view of this, there is an urgent need for a new type of air fryer on the market to solve the problems of poor hot air circulation and uneven heating of the top and bottom of the food in existing air fryers. Utility Model Content

[0014] In one embodiment, the cross-sectional area of ​​the second air guide gradually decreases along the bottom wall from the outside to the inside, and the cross-sectional area of ​​the first air guide is smaller than that of the second air guide in the same cross-section.

[0015] In one embodiment, eight air guides are evenly spaced around the air gathering edge;

[0016] Furthermore, the eight air guides divide the bottom wall of the inner liner into eight sub-walls.

[0017] In one embodiment, the wind-gathering edge is an annular protrusion surrounding the middle of the bottom wall;

[0018] The air-gathering edge is provided with a recessed arc-shaped part that is smoothly connected to the bottom wall on the side facing the inner liner peripheral wall;

[0020] The inclined portion and the bottom wall together form a holding area located at the center of the bottom wall.

[0021] In one embodiment, the wind-gathering edge forms an annular wind-gathering zone, and the area of ​​the annular wind-gathering zone is 1 / 8 to 1 / 6 of the area of ​​the bottom wall.

[0022] In one embodiment, an arc-shaped air guide surface is formed at the connection between the side wall of the inner liner and the bottom wall;

[0023] The radius of the rounded corners of the arc-shaped air guide surface ranges from 10mm to 20mm.

[0024] In one embodiment, the pot body includes an inner shell and an outer shell that is fitted over the outer side of the inner shell, and the inner shell and the outer shell form an air guide channel;

[0025] The bottom of the outer casing has a first air inlet, and the top of the outer casing has a second air inlet;

[0052] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0053] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0054] Combination Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides an air fryer, which includes a pot body 1, an inner liner 2 and a hot air device 3; the inner liner 2 is detachably disposed inside the pot body 1, and the top of the inner liner 2 has an opening and the bottom has a bottom wall; the hot air device 3 is disposed in the pot body 1 and corresponds to the inner liner 2, and can guide hot air toward the opening.

[0055] The bottom wall has a central protrusion with a converging edge 21 and multiple guide edges 22 that surround and connect the converging edge 21. The multiple guide edges 22 are all arc-shaped ribs in the same direction of rotation, and the other end of the guide edge 22 extends to the peripheral edge of the bottom wall and connects to the inner wall of the inner liner 2. One side wall of the guide edge 22 is inclinedly connected to the bottom wall to form a first guide part 221, and the other side is inclinedly connected to the bottom wall to form a second guide part 222. The angle between the first guide part 221 and the bottom wall is set between 35° and 40°. The angle between the second guide part 222 and the bottom wall is set between 20° and 30°.

[0056] The hot air device 3 of the air fryer provided in this embodiment can be, but is not limited to, configured as an "electric heating wire + fan" structure. In this way, the electric heating wire generates heat when energized, and the fan blows air through the electric heating wire and then guides it into the inner pot 2, thereby achieving the heating and cooking of the food in the inner pot 2.

[0057] Furthermore, since the bottom wall of the inner liner 2 is provided with a converging edge 21 and multiple guide edges 22 that are arranged around and connected to the converging edge 21, when the hot air delivered by the hot air device 3 enters the bottom wall of the inner liner 2, the multiple arc-shaped guide edges 22 arranged in the same direction of rotation can spirally converge and guide the hot air from the outside to the inside. When the hot air is guided to the converging edge 21 in the middle of the bottom wall, the converging edge 21 can also guide the hot air upward to a certain extent, so that the hot air entering the bottom wall of the inner liner 2 can sequentially follow the flow path of "spiral convergence + convergence and lifting". When the hot air rises to a certain height, it can be blown downward and flowed back by the hot air device 3, thereby realizing the effect of hot air circulating in the inner liner 2, so that the food in the inner liner 2 can be heated efficiently on both the top and bottom sides.

[0058] In addition, a first air guide section 221 is formed by obliquely connecting one side wall of the air guide 22 to the bottom wall, and the angle between the first air guide section 221 and the bottom wall is set between 35° and 40°, for example, 38°; a second air guide section 222 is formed by obliquely connecting the other side of the air guide 22 to the bottom wall, and the angle between the second air guide section 222 and the bottom wall is set between 20° and 30°, for example, 26°. In this way, different hot air guiding angles can be formed on both sides of the air guide 22, so that hot air with different flow rates and different rise rates can be generated on both sides of the air guide 22, thereby forming more types of hot air and heating the food in the inner pot 2 better and more evenly.

[0059] In summary, the air fryer provided in this embodiment of the present disclosure has a converging edge 21 protruding from the middle of the bottom wall of the inner pot 2, and multiple guide edges 22 surrounding and connected to the converging edge 21. The guide edges 22 are respectively provided with a first guide part 221 and a second guide part 222 with different inclination angles of the bottom wall. This allows hot air to enter the bottom wall of the inner pot 2 and form multiple streams of hot air with different flow rates, different lift rates and different paths. The hot air can be spirally converged and then converged and lifted by the converging edge 21. This ensures that the food in the inner pot 2 can be heated more evenly, more comprehensively and more efficiently on both the upper and lower sides at the same time.

[0060] In one embodiment, along the bottom wall from the outside to the inside, the first air guide 221 includes a first sub-segment 221a and a second sub-segment 221b that are smoothly connected, and the cross-sectional areas of the first sub-segment 221a and the second sub-segment 221b gradually decrease.

[0061] Specifically, in combination Figure 3 In further detail, the first air guide section 221 is specifically configured to include a smoothly connected first sub-segment 221a and second sub-segment 221b. Moreover, the cross-sectional area of ​​the first sub-segment 221a and the second sub-segment 221b gradually decreases along the bottom wall from the outside to the inside. In this way, the first air guide section 221 can form a gradually narrowing arc-shaped structure. When the hot air gradually spirals and converges from the outer periphery of the bottom wall to the center, the spiral tilt angle of the hot air moving along the first air guide section 221 will gradually decrease and the speed will gradually increase, so as to achieve the effect of accelerating the convergence towards the air gathering line 21.

[0062] In one embodiment, the cross-sectional area of ​​the second air guide 222 gradually decreases along the bottom wall from the outside to the inside, and the cross-sectional area of ​​the first air guide 221 in the same cross section is smaller than the cross-sectional area of ​​the second air guide 222.

[0063] Specifically, in combination Figure 3To elaborate further, the cross-sectional area of ​​the second air guide 222 is also set to gradually decrease from the outside to the inside along the bottom wall. In the same cross-section, the cross-sectional area of ​​the first air guide 221 is smaller than that of the second air guide 222. In this way, the hot air that gradually spirals and converges from the outer periphery of the bottom wall to the center along the second air guide 222 can also travel in a manner where the spiral tilt angle gradually decreases and the speed gradually increases. Furthermore, since the cross-sectional area of ​​the first air guide 221 is smaller than that of the second air guide 222 in the same cross-section, the hot air moving along the second air guide 222 and the hot air moving along the first air guide 221 can form different movement trajectories with different guiding angles, thereby generating more types of hot air and heating the food in the inner pot 2 better and more evenly.

[0064] In one embodiment, eight air guides 22 are evenly spaced around the air gathering edge 21; and the eight air guides 22 divide the bottom wall of the inner liner 2 into eight sub-walls.

[0065] Specifically, in combination Figure 3 In further detail, eight air guides 22 are evenly spaced around the air converging edge 21, and the eight air guides 22 divide the bottom wall of the inner liner 2 into eight sub-walls. In this way, the vent edges of the outer peripheral wall of the bottom wall of the inner liner 2 can move along the eight air guides 22 (each air guide 22 includes a first air guide section 221 and a second air guide section 222) and along the eight sub-walls, thereby forming at least twenty-four types of hot air converging and moving towards the air converging edge 21.

[0066] In one embodiment, the air-gathering edge 21 is an annular protrusion surrounding the middle of the bottom wall; the side of the air-gathering edge 21 facing the circumferential wall of the inner liner 2 is provided with a recessed arc-shaped portion 211 that is smoothly connected to the bottom wall.

[0067] Specifically, in combination Figure 2 and Figure 3 In further detail, the converging edge 21 is specifically set as a square annular protrusion surrounding the middle of the bottom wall. Of course, the converging edge 21 can also be set as a circular annular protrusion, a hexagonal annular protrusion, or an irregular annular protrusion, etc. Furthermore, a recessed arc-shaped part 211 that smoothly connects to the bottom wall is provided on the side of the converging edge 21 facing the inner liner 2. In this way, when hot air moves from the outer peripheral wall of the inner liner 2 along the bottom wall toward the converging edge 21, the recessed arc-shaped part 211 can gradually change the direction and lift the hot air, thereby avoiding the converging edge 21 from causing a large obstruction to the flow rate of the hot air, allowing the hot air to flow upward through the converging edge 21 while ensuring the upward flow rate of the hot air.

[0068] In one embodiment, an inclined portion 212 is provided on the side of the air-collecting edge 21 facing the center of the inner liner 2, which is inclinedly connected to the bottom wall; the inclined portion 212 and the bottom wall together form a holding area 213 located at the center of the bottom wall.

[0069] Specifically, in combination Figure 2 and Figure 3 In further detail, an inclined section 212 is provided on the side of the air-collecting edge 21 facing the center of the inner liner 2, which is inclinedly connected to the bottom wall. The inclined section 212 and the bottom wall together form a holding area 213 located in the center of the bottom wall. In this way, cooking seasonings (such as water, oil, sauce, cream, etc.) can be placed in the holding area 213 to better improve the taste and flavor of the food when it is processed at high temperature in the air fryer.

[0070] In one embodiment, the wind-gathering edge 21 forms an annular wind-gathering zone, and the area of ​​the annular wind-gathering zone is 1 / 8 to 1 / 6 of the area of ​​the bottom wall.

[0071] Specifically, in combination Figure 2 and Figure 3 To explain in more detail, the annular air-gathering area formed by the air-gathering edge 21 is set to 1 / 8 to 1 / 6 of the bottom wall area of ​​the inner liner 2. This ensures that the annular air-gathering area is of a moderate size, which on the one hand can form a good gathering and lifting effect on the incoming hot air, and on the other hand does not occupy too much area of ​​the bottom wall of the inner liner 2, ensuring that the air-guiding edge 22 has sufficient guiding length.

[0072] In one embodiment, an arc-shaped air guide surface 23 is formed at the connection between the side wall and the bottom wall of the inner liner 2; the radius of the rounded corner of the arc-shaped air guide surface 23 is in the range of 10mm to 20mm.

[0073] Specifically, in combination Figure 4 In further detail, an arc-shaped air guide surface 23 is provided at the connection between the side wall and the bottom wall of the inner liner 2, and the radius of the rounded corner of the arc-shaped air guide surface 23 is in the range of 10mm to 20mm. This ensures a smooth transition between the side wall and the bottom wall of the inner liner 2, and ensures that when the hot air at the side wall of the inner liner 2 flows downward to the bottom wall, it can be efficiently diverted and guided by the arc-shaped air guide surface 23, reducing the flow velocity obstruction of the hot air.

[0074] In one embodiment, the pot body 1 includes an inner shell 102 and an outer shell 101 that is fitted over the inner shell 102, and the inner shell 102 and the outer shell 101 form an air guide channel; a first air inlet 111 is provided at the bottom of the outer shell 101, and a second air inlet 112 is provided at the top of the outer shell 101; an exhaust port 113 is also provided on the side of the outer shell 101, and the hot air device 3 also includes an exhaust fan corresponding to the exhaust port 113; wherein, the first air inlet 111, the air guide channel, the exhaust fan and the exhaust port 113 can be sequentially connected to form a first heat dissipation air path; the second air inlet 112, the exhaust fan and the exhaust port 113 can be sequentially connected to form a second heat dissipation air path.

[0075] Specifically, in combination Figure 1 In further detail, two first air inlets 111 can be specifically provided at the bottom of the outer shell 101, and both first air inlets 111 can be connected in sequence through an air guide, an exhaust fan, and an exhaust port 113 to form a first heat dissipation air path. In this way, external air can be introduced from the bottom of the outer shell 101 and discharged from the side of the outer shell 101 through the first heat dissipation air path, thereby achieving heat dissipation of the lower half of the pot body 1; one second air inlet 112 can be specifically provided at the top of the outer shell 101, and two second air inlets 112 can be connected in sequence through an exhaust fan and an exhaust port 113 to form a second heat dissipation air path. In this way, external air can be introduced from the top of the outer shell 101 and discharged from the side of the outer shell 101 through the second heat dissipation air path, thereby achieving heat dissipation of the upper half of the pot body 1.

[0076] The specific configuration of the pot body 1 described above can effectively dissipate heat inside the pot body 1, ensuring that the electrical components inside the pot body 1 are within a safe temperature range when the air fryer is in use.

[0077] In one embodiment, a switch assembly 4 is also provided in the outer wall of the pot body 1; the switch assembly 4 includes a temperature switch 41 and a timer switch 42, as well as a temperature knob 43 that is operatively connected to the temperature switch 41 and a timer knob 44 that is operatively connected to the timer switch 42; wherein the temperature knob 43 and the timer knob 44 can respectively adjust the working state of the temperature switch 41 and the timer switch 42 by turning them.

[0078] Specifically, in combination Figure 1 and Figure 5 In further detail, a switch assembly 4 is also provided in the outer wall of the pot body 1. The switch assembly 4 includes a temperature switch 41 and a timer switch 42, as well as a temperature knob 43 that is driven to the temperature switch 41 and a timer knob 44 that is driven to the timer switch 42. In this way, the heating temperature and heating time of the air fryer can be adjusted by turning them respectively.

[0079] In one embodiment, the switch assembly 4 further includes a switch bracket 45 and a knob bracket 46; a temperature switch 41 and a timer switch 42 are mounted side by side on the switch bracket 45; one end of the knob bracket 46 is fixedly connected to the switch bracket 45; wherein, the temperature knob 43 is rotatably sleeved on the outside of the knob bracket 46 and is connected to the temperature switch 41 through a transmission gear set; the timer knob 44 is rotatably inserted inside the knob bracket 46 and one end is directly connected to the timer switch 42.

[0080] Specifically, in combination Figure 5 and Figure 6 In further detail, the switch assembly 4 is also provided with a switch bracket 45 and a knob bracket 46. The temperature switch 41 and the timer switch 42 are installed side by side on the switch bracket 45. One end of the knob bracket 46 is fixedly connected to the switch bracket 45. In this way, the temperature knob 43 can be rotatably sleeved on the outside of the knob bracket 46 and is connected to the temperature switch 41 through a transmission gear set. The timer knob 44 can be rotatably inserted into the inside of the knob bracket 46 and one end is directly connected to the timer switch 42. This design makes the overall structure of the switch assembly 4 more compact and small. Moreover, the rotation adjustment of the timer knob 44 and the temperature knob 43 is independent and does not affect each other.

[0081] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise explicitly specified.

[0082] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
