Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, specifically to an air fryer. Background Technology

[0002] An air fryer is a cooking appliance that primarily heats and bakes food using rapidly circulating hot air. It consists of a main fryer body and a drum with an opening at the top. The drum is used to hold food, and after being placed inside the main fryer body, a heating element is located at the top. A circulating fan circulates the air, which enters the drum through the opening at the top and is heated by the heating element before entering. This rapid circulation of hot air heats and bakes the food inside the drum.

[0003] However, when using an air fryer, baking is best when only a single layer of food is set up. When multiple layers of food are placed inside the fryer, the hot air enters from the opening at the top of the fryer and can only blow directly onto the food on the top layer, resulting in poor baking of the food in the middle or bottom layers.

[0004] Therefore, how to solve or improve the problem of poor baking effect of air fryers on food in the middle or bottom of the frying drum has become an important technical problem to be solved by those skilled in the art. Utility Model Content

[0019] A baffle is connected to the side wall of the frying barrel, on which an air inlet is provided. The baffle is located on the side of the air inlet near the first air guide groove. The baffle is inclined in the direction away from the side wall of the frying barrel in the direction close to the air cavity. The air inlet is formed between the side of the baffle close to the air cavity and the side wall of the frying barrel.

[0020] Optionally, it also includes:

[0021] The first exhaust vent is located on the left side of the fryer body and is connected to the air cavity;

[0023] Optionally, the cross-sectional area of ​​the first air guide groove gradually decreases along the direction away from the air cavity.

[0024] Optionally, it also includes:

[0025] An oil collection tray is placed inside the frying drum, and the grill racks are stacked sequentially on the oil collection tray.

[0026] This application provides an air fryer, comprising: an air fryer body, a circulating impeller, a heating element, an air fryer drum, and a grill rack. The air fryer body has a cavity, and a partition within the cavity divides the cavity into an air fryer drum cavity and an air chamber. First perforations are formed through both sides of the partition, and first air guide slots are formed on the side walls of both sides of the air fryer drum cavity. Each first air guide slot communicates with the air chamber through a corresponding first perforation.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The following is combined Figures 1 to 8 This describes an embodiment of the present application.

[0041] According to embodiments of this application, in one aspect, an air fryer is provided, such as... Figure 1 and Figure 2 As shown, it includes: fryer body, circulating fan 1, heating element, frying bucket 3 and grill rack 2.

[0042] The fryer body has a cavity, and a partition 4 is installed inside the cavity, dividing the cavity into a frying chamber 5 and an air chamber 6. A first through hole 41 is provided on both sides of the partition 4, and a first air guide groove 51 is provided on the side walls on both sides of the frying chamber 5. Each first air guide groove 51 is connected to the air chamber 6 through a corresponding first through hole 41.

[0043] The circulating fan 1 is rotatably disposed in the air cavity 6, so that when the circulating fan 1 rotates, it guides the airflow in the air cavity 6 to the outside of the circulating fan 1.

[0044] A heating element is installed inside the air cavity 6, which can heat the airflow inside the air cavity 6. The heating element can be an electric heating tube or a heating rod.

[0045] The frying drum 3 is placed inside the frying drum cavity 5. For example... Figures 3 to 5 As shown, the front side of the frying chamber 5 is open, so that the frying barrel 3 can be inserted into the frying chamber 5 from the front side.

[0046] The partition 4 has a second perforation 42. When the frying drum 3 is placed inside the frying drum cavity 5, the rear side wall of the frying drum 3 is sealed with the second perforation 42. Multiple return air holes 32 are provided through the rear side wall of the frying drum 3, so that the inside of the frying drum 3 is connected to the second perforation 42 through the return air holes 32.

[0047] like Figure 6 and Figure 7 As shown, multiple air inlets 31 are provided on both the left and right sides of the frying barrel 3, and the air inlets 31 are evenly distributed on the left and right sides of the frying barrel 3. When the frying barrel 3 is placed inside the frying barrel cavity 5, the first air guide channels 51 located on both sides of the frying barrel 3 are connected to the inside of the frying barrel 3 through the air inlets 31.

[0048] Two or more grill racks 2 can be set up, with at least two grill racks 2 stacked one on top of the other inside the frying barrel 3.

[0049] In this way, food can be placed at the bottom of the frying drum 3 and on the stacked grill racks 2, allowing the food to be arranged in multiple layers from top to bottom. Then, the heating element is used to heat the airflow in the air chamber 6, while driving the circulating fan 1 to rotate, so that the circulating fan 1 guides the hot air in the air chamber 6 to the side wall of the air chamber 6.

[0050] Since the two first perforations 41 are located on both sides inside the air cavity 6, the hot air inside the air cavity 6 enters the first air guide grooves 51 on both sides of the frying barrel 3 from the first perforations 41 on both sides respectively.

[0051] Subsequently, hot air from the first air guide slot 51 on the left side of the frying drum 3 enters the frying drum 3 through the air inlet 31 on the left side wall of the frying drum 3 and blows towards the food from left to right for frying. Meanwhile, hot air from the first air guide slot 51 on the right side of the frying drum 3 enters the frying drum 3 through the air inlet 31 on the right side wall of the frying drum 3 and blows towards the food from right to left for frying. In this way, hot air can be evenly blown from both sides to each layer of food, so that the food in the middle or bottom layers can also achieve a good frying effect.

[0052] Furthermore, because the food is placed on grill 2, there are gaps between the food on adjacent layers, resulting in better frying of each layer of food.

[0053] After the hot air fries the food, it returns to the air chamber 6 through the return air hole 32 on the rear side wall of the frying barrel 3. It is then heated by the heating element and guided by the circulating fan wheel 1 to the side wall of the air chamber 6 to form circulating air, so as to continuously fry the food.

[0054] The circulating fan 1 is connected to the power unit 7 via a transmission. The power unit 7 can be an electric motor, which can drive the circulating fan 1 to rotate.

[0055] As an optional embodiment, such as Figure 1 As shown, the air fryer also includes an auxiliary heating element 24. The auxiliary heating element 24 can be an electric heating tube or a heating rod.

[0056] The auxiliary heating element 24 is set in the first air guide groove 51, wherein the auxiliary heating element 24 is set in the first air guide groove 51 on both sides of the frying barrel cavity 5.

[0057] Thus, for the first air guide slot 51 located on the left side of the frying barrel 3, when the hot air in the air cavity 6 enters the first air guide slot 51 through the corresponding first perforation 41, the auxiliary heating element 24 in the first air guide slot 51 further heats the hot air, and then the reheated hot air enters the interior of the frying barrel 3 through the air inlet 31 on the left side wall of the frying barrel 3 to fry the food inside the frying barrel 3.

[0058] For the first air guide slot 51 located on the right side of the frying barrel 3, when the hot air in the air cavity 6 enters the first air guide slot 51 through the corresponding first perforation 41, the auxiliary heating element 24 in the first air guide slot 51 further heats the hot air, and then the reheated hot air enters the interior of the frying barrel 3 through the air inlet 31 on the right side wall of the frying barrel 3 to fry the food inside the frying barrel 3.

[0059] In this way, before frying the food, the hot air is reheated by an auxiliary heating device to increase the temperature of the hot air, making the frying effect of the hot air on the food better.

[0060] As an optional embodiment, such as Figure 2As shown, a second air guide slot 52 is provided on the upper side wall of the frying drum cavity 5, so that the second air guide slot 52 is connected to the air cavity 6 through the airflow channel 43 at the upper part of the partition 4, and a guide plate 521 is provided inside the second air guide slot 52. The guide plate 521 is adapted to guide the airflow away from the air cavity 6 downward. When the frying drum 3 is placed in the frying drum cavity 5, the second guide slot is located above the top opening of the frying drum 3, so that the second guide slot is connected to the top opening of the frying drum 3.

[0061] After placing the food at the bottom of the frying drum 3 and on the stacked grill racks 2, the heating element heats the airflow inside the air chamber 6, while simultaneously driving the circulating fan 1 to rotate, causing the circulating fan 1 to guide the hot air inside the air chamber 6 towards the side wall of the air chamber 6. At this time, the hot air inside the air chamber 6 enters the first air guide grooves 51 on both sides of the frying drum 3 through the first perforations 41 on both sides, and also enters the second air guide groove 52 on the upper side wall of the frying drum cavity 5 through the airflow channel 43 at the top of the partition 4.

[0062] Hot air from the first air guide slot 51 on the left side of the frying drum 3 enters the frying drum 3 through the air inlet 31 on the left side wall of the frying drum 3 and blows towards the food from left to right for frying. Meanwhile, hot air from the first air guide slot 51 on the right side of the frying drum 3 enters the frying drum 3 through the air inlet 31 on the right side wall of the frying drum 3 and blows towards the food from right to left for frying. This ensures that hot air is evenly distributed from both sides to each layer of food, resulting in good frying results even for the middle or bottom layers.

[0063] Meanwhile, the airflow in the second air guide groove 52 on the upper side wall of the frying drum 5 flows away from the air cavity 6, and after flowing to the guide plate 521, it flows downward under the guidance of the guide plate 521, thus entering the frying drum 3 from the opening at the top of the frying drum 3. This increases the flow rate of hot air entering the frying drum 3, accelerates the circulation of hot air, and improves the frying effect on food.

[0064] The guide plate 521 can be an arc-shaped plate or a straight plate. One side of it is connected to the bottom surface of the second air guide trough 52, and the other side is inclined towards the frying barrel 3 in a direction away from the air cavity 6. So when the airflow flowing away from the air cavity 6 hangs on the guide plate 521, the guide plate 521 guides the airflow downward, that is, towards the direction closer to the frying barrel 3.

[0065] In optional embodiments, such as Figure 2 As shown, in the direction away from the air cavity 6, the flow cross-sectional area of ​​the second air guide groove 52 gradually decreases, that is, the second air guide groove 52 gradually narrows in the direction away from the air cavity 6.

[0066] As the airflow moves away from the air cavity 6 in the second air guide slot 52, the airflow pressure gradually increases due to the gradual decrease in the flow cross-sectional area, which in turn increases the airflow velocity.

[0067] In this way, the hot air in the air cavity 6 enters the second air guide groove 52 on the upper side wall of the frying drum cavity 5 through the airflow channel 43 at the top of the partition 4. In the second air guide groove 52, the air flows away from the air cavity 6, and the flow velocity continuously increases until it is guided downwards by the guide plate 521. This allows the hot air to enter the frying drum 3 at a faster flow rate, resulting in better frying of the food. It also accelerates the circulation speed of the hot air, improving frying efficiency.

[0068] As an optional embodiment, such as Figure 1 and Figure 2 As shown, the sidewalls of the air chamber 6 are arc surfaces, that is, the left sidewall, right sidewall, upper sidewall and lower sidewall of the air chamber 6 are all arc surfaces, and the arc surfaces are concave in the direction away from the frying chamber 5.

[0069] In this way, after the circulating fan 1 is driven to rotate, it causes the circulating fan 1 to guide the hot air in the air cavity 6 to the side wall of the air cavity 6. Under the guidance of the left side wall of the air cavity 6, the hot air flowing to the left side of the air cavity 6 is turned and flows closer to the frying barrel cavity 5, and thus enters the first air guide groove 51 on the left side wall of the frying barrel cavity 5 through the first perforation 41 on the left side of the partition 4.

[0070] The hot air flowing to the right side wall of the air chamber 6 is guided by the right side wall of the air chamber 6, and the hot air is turned and flows closer to the frying barrel cavity 5, so that it enters the first air guide groove 51 on the right side wall of the frying barrel cavity 5 through the first perforation 41 on the right side of the partition 4.

[0071] The hot air flowing to the upper side wall of the air chamber 6 is guided by the upper side wall of the air chamber 6, and the hot air is turned and flows closer to the frying barrel cavity 5, thus entering the second air guide groove 52 on the upper side wall of the frying barrel cavity 5 through the airflow channel 43 above the partition 4.

[0072] As an optional embodiment, such as Figure 2 As shown, the air inlets 31 on the left and right sides of the frying drum 3 are positioned facing the air chamber 6. After the driving fan 1 rotates, it guides the hot air in the air chamber 6 to the side wall of the air chamber 6.

[0073] The hot air flowing towards the left side wall of the air chamber 6 enters the first air guide groove 51 on the left side wall of the frying drum 5 through the first perforation 41 on the left side of the partition 4, and then flows away from the air chamber 6. Since the air inlet 31 on the left side wall of the frying drum 3 is oriented towards the air chamber 6, meaning the orientation of the air inlet 31 is opposite to the direction of the hot air flow, the hot air flowing away from the air chamber 6 can directly enter the air inlet 31 and into the frying drum 3. This reduces the resistance of the hot air and minimizes energy loss before entering the air inlet 31.

[0074] Hot air flowing towards the right side wall of the air chamber 6 enters the first air guide groove 51 on the right side wall of the frying drum cavity 5 through the first perforation 41 on the right side of the partition 4, and then flows away from the air chamber 6. Since the air inlet 31 on the right side wall of the frying drum 3 is oriented towards the air chamber 6, meaning the orientation of the air inlet 31 is opposite to the direction of the hot air flow, the hot air flowing away from the air chamber 6 can directly enter the air inlet 31 and into the frying drum 3. This reduces the resistance of the hot air and minimizes energy loss before entering the air inlet 31.

[0075] In optional embodiments, such as Figure 6 and Figure 7 As shown, the air fryer also includes a baffle 33.

[0076] In the side wall of the frying drum 3, an air inlet is provided on the left side wall. A baffle 33 has opposing first and second sides. The first side of the baffle 33 is connected to the outer left side wall of the frying drum 3, and the baffle 33 is located on the side of the air inlet near the first air guide groove 51. In the direction near the air cavity 6, the baffle 33 is inclined away from the left side wall of the frying drum 3, so that the second side of the baffle 33 is spaced apart from the left side wall of the frying drum 3. The second side of the baffle 33 and the left side wall of the frying drum 3 cooperate with the air inlet to form an air inlet 31 facing the air cavity 6. Airflow can pass between the second side and the left side wall of the frying drum 3 and then through the air inlet to enter the frying drum 3.

[0077] An air inlet is provided on the right side wall of the frying drum 3. A baffle 33 has opposing first and second sides. The first side of the baffle 33 is connected to the outer right side wall of the frying drum 3, and the baffle 33 is located on the side of the air inlet near the first air guide groove 51. In the direction close to the air cavity 6, the baffle 33 is inclined away from the right side wall of the frying drum 3, so that the second side of the baffle 33 is spaced apart from the right side wall of the frying drum 3. The second side of the baffle 33 and the right side wall of the frying drum 3 cooperate with the air inlet to form an air inlet 31 facing the air cavity 6. Airflow can pass between the second side and the right side wall of the frying drum 3 and then through the air inlet to enter the frying drum 3.

[0078] In some embodiments, such as Figure 6 and Figure 7 As shown, for the left side wall of the frying drum 3, an air inlet can be formed by punching the left side wall of the frying drum 3 outward, while the first side of the original material at the air inlet remains adhered to the left outer wall of the frying drum 3, thereby forming a baffle 33. The second side of the original material at the air inlet separates from the left outer wall of the frying drum 3 and fits with the air inlet to form an air inlet 31.

[0079] Similarly, for the right side wall of the frying drum 3, an air inlet can be formed by punching the right side wall of the frying drum 3 outward, while the first side of the original material at the air inlet remains adhered to the right outer wall of the frying drum 3, thus forming a baffle 33. The second side of the original material at the air inlet separates from the right outer wall of the frying drum 3 and cooperates with the air inlet to form an air inlet 31.

[0080] This setup simplifies processing, saves materials, and reduces manufacturing costs.

[0081] The air inlets 31 are evenly arranged on the left and right walls of the fryer 3, and can be arranged in a rectangular array in the length and height directions.

[0082] As an optional embodiment, such as Figure 4 , Figure 5 and Figure 8 As shown, the air fryer also includes a first exhaust port 8 and a second exhaust port 9. The first exhaust port 8 is located on the left side of the fryer body and is connected to the air cavity 6, so that the airflow in the air cavity 6 can be discharged from the left side of the fryer body through the first exhaust port 8.

[0083] The second exhaust port 9 is located on the right side of the fryer body and is connected to the air cavity 6, so that the airflow in the air cavity 6 can be discharged from the right side of the fryer body through the second exhaust port 9.

[0084] The first smoke outlet 8 and the second smoke outlet 9 are symmetrically arranged on the left and right sides.

[0085] Under the action of the circulating impeller 1, the circulating hot air fries the food. The fumes generated during frying are also mixed in with the airflow. When the fumes return to the air chamber 6, the circulating impeller 1 guides the fumes-laden airflow to the side wall of the air chamber 6, allowing a portion of the fumes-containing airflow to be discharged from the first exhaust port 8 and the second exhaust port 9. As the airflow circulates, the first exhaust port 8 and the second exhaust port 9 continuously discharge fumes-containing airflow, thus achieving fume emission.

[0086] Since the first smoke exhaust port 8 and the second smoke exhaust port 9 are symmetrically arranged on the left and right sides, the uneven smoke exhaust from the first smoke exhaust port 8 and the second smoke exhaust port 9 is avoided from causing the airflow circulation in the air cavity 6 to be deflected.

[0087] In an optional embodiment, the flow cross-sectional area of ​​the first air guide groove 51 gradually decreases in the direction away from the air cavity 6, that is, the first air guide groove 51 gradually narrows in the direction away from the air cavity 6.

[0088] As the airflow moves away from the air cavity 6 in the first air guide slot 51, the airflow pressure gradually increases due to the gradual decrease in the flow cross-sectional area, thereby increasing the airflow velocity.

[0089] In this way, the hot air in the air cavity 6 enters the first air guide grooves 51 on the left and right sides of the frying drum cavity 5 through the first perforation 41. Within the first air guide grooves 51, the air flows away from the air cavity 6, continuously increasing its velocity until it enters the frying drum 3 through the air inlet 31. The faster flow of hot air into the frying drum 3 results in better frying of the food. It also accelerates the circulation of hot air, improving frying efficiency.

[0090] As an optional embodiment, the air fryer also includes an oil drip tray 10. The oil drip tray 10 is disposed at the bottom of the frying drum 3, and the grill racks 2 are arranged sequentially from top to bottom on the upper part of the oil drip tray 10. That is, the bottommost grill rack 2 is placed on the oil drip tray 10, and food is placed on the oil drip tray 10 and each grill rack 2.

[0091] As an optional embodiment, such as Figure 8 As shown, the fryer body includes an outer shell with a front opening, consisting of a base 11, an upper cover 12, and a rear cover 13. It also includes an inner cover with a front opening, consisting of a bottom cover 14, an upper cover 15, and a rear cover 16. The outer shell is located around the inner cover and provides protection. The bottom cover 14, upper cover 15, and rear cover 16 form a cavity, and a partition 4 is disposed within the bottom cover 14, dividing the cavity into a frying chamber 5 and an air chamber 6.

[0092] A motor bracket 23 is provided between the rear cover 16 and the rear plate, and the motor, which serves as the power unit 7, is mounted on the motor bracket 23. The drive shaft of the motor passes through the rear cover 16 and is connected to the circulating fan wheel 1 inside the air chamber 6.

[0093] A placement groove is provided on the top surface of the upper cover 12, and a control board bracket 17 is provided in the placement groove. A control board 18 is installed on the control board bracket 17. A panel cover 19 is connected to the top surface of the upper cover 12, so that the panel cover 19 closes the placement groove.

[0094] A door frame 20 is provided at the front opening of the inner casing. A frame 21 matching the door frame 20 is connected to the front outer wall of the frying barrel 3. When the frying barrel 3 is inserted into the frying barrel cavity 5, the frame 21 is matched and connected to the door frame 20 to support the frying barrel 3.
