Description

Technical Field

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

[0002] Air fryers rely on a hot air unit to generate hot air to heat and cook food in the cooking chamber. To improve heating efficiency and enhance the texture of food, some air fryers are equipped with a steam generator that supplies steam into the cooking chamber. This high-temperature steam assists in heating the food and replenishes its moisture, accelerating cooking and preventing the food from becoming dry. However, using a steam generator to supply steam to the cooking chamber is relatively complex and costly, and the generated steam temperature is relatively low, which limits the overall heating efficiency within the cooking chamber to some extent.

[0003] Besides using a steam generator, some air fryers have a bottom heating element at the bottom of the pot. Water is added to the pot, and the bottom heating element heats the water to generate steam. To improve the heating effect of the steam on the food, additional heating structures are installed on the side of the pot to reheat the rising steam into high-temperature steam, thus increasing the steam temperature for better food heating. Although this solution improves the heating effect of steam on food, the use of multiple heating structures leads to complex structure and higher cost. Utility Model Content

[0004] This utility model provides an air fryer, aiming to solve the technical problem of the complex structure of existing air fryers with steam function to achieve secondary steam heating.

[0005] This utility model discloses an air fryer, including a main body, a pot body disposed within the main body, a hot air assembly disposed above the pot body, a water replenishment device for adding water to the pot body, and a baking tray disposed within the pot body. A heating element and a temperature controller are disposed on the outer bottom of the pot body. A mounting area is formed by a recess in the center of the bottom wall of the pot body, and the temperature controller is attached to the lower surface of the mounting area. The pot wall below the upper surface of the mounting area forms a water storage area. An overheating area is provided in the pot wall at a region not lower than the upper surface of the mounting area. Both the water storage area and the overheating area are lower than the baking tray. The heating element simultaneously covers both the water storage area and the overheating area. The water replenishment device controls the water level in the water storage area to be below the upper surface of the mounting area. The water in the water storage area evaporates upon heating to form steam, which is then reheated by the overheating area during its ascent.

[0006] The air fryer of this utility model also has the following additional technical features:

[0007] The water storage area and the superheated area are arranged adjacent to each other.

[0008] The area of ​​the overheated zone is larger than the area of ​​the water storage zone.

[0009] The hot air assembly includes a centrifugal fan, and the water storage area is located outside the superheated area.

[0010] The bottom of the pot body sinks from the center to both sides and forms a water storage area near the edge. The heating element is a heating plate, and the top surface of the heating plate rises from both sides to the center to fit against the bottom of the pot body.

[0011] The bottom wall and side wall of the pot are connected by an arc-shaped corner, and at least part of the overheating zone is located in the area where the corner is located, and the water storage zone is located inside the overheating zone.

[0012] The heating element includes an aluminum heat-conducting plate and a heating tube disposed on the aluminum heat-conducting plate. The heating tube is a single-ring shape and is disposed between the water storage area and the overheating area.

[0013] The heating element includes an aluminum heat-conducting plate and a heating tube disposed on the aluminum heat-conducting plate. The heating tube is a multi-ring shape and is respectively disposed corresponding to the water storage area and the overheating area.

[0014] The hot air assembly includes a heating element and a centrifugal fan, and the projection of the heating element on the bottom of the pot body falls within the overheated zone.

[0015] An elastic element is provided below the heating element, which allows the heating element to be attached to the lower surface of the pot body.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. The air fryer of this utility model simplifies the structural configuration and reduces component costs by setting a single heating element at the bottom of the pot body to achieve secondary steam heating. By limiting the water level in the water storage area, it can be ensured that the water in the water storage area is completely evaporated to form steam. Moreover, since the heating element covers both the water storage area and the superheated area at the same time, the steam can be reheated by the superheated area during the rising process, which can effectively increase the steam temperature, thereby improving the heating effect of the steam on the food and improving the taste of the food.

[0018] It is understandable that during the rising process of steam, due to the difference in the time it takes for the steam to be heated by the superheated zone, at least some of the steam is heated to a higher temperature than the original steam temperature after being reheated. Additionally, the reheating of some steam can compensate for the temperature drop of the steam. Overall, this can slow down the rate of temperature drop of the steam, so that the steam has a higher temperature when it comes into contact with the food, thereby improving the heating effect of the food.

[0019] 2. In order to enable most of the steam to be reheated during the rising process, the water storage area and the superheated area are arranged adjacent to each other. The steam closer to the superheated area is reheated faster and at a higher temperature, which is beneficial to improving heat utilization and increasing the amount of high-temperature steam generated, thereby improving the heating effect on food. Moreover, it is beneficial to reduce the radial dimension of the heating element and further save material costs.

[0020] 3. In order to increase the amount of high-temperature steam generated, the area of ​​the superheated zone is larger than the area of ​​the water storage zone, so that the superheated zone generates more heat and covers a larger area, thereby fully heating the rising steam, further slowing down the rate of steam temperature drop, and improving the effect of steam on food.

[0021] 4. When the hot air assembly is equipped with a centrifugal fan, the hot air generated by the hot air assembly will move downward along the side wall of the pot under the action of the centrifugal fan. In order to improve the secondary heating effect of the steam, the water storage area is located outside the superheated area. The water storage area is close to the side wall of the pot. After the water storage area generates steam, the steam can be heated on both sides by the hot air blown down from above and the heat from the superheated area. This not only achieves sufficient secondary heating, but also increases the temperature of the steam, which is beneficial to improve the cooking efficiency of the food and improve the taste of the food.

[0022] Furthermore, the bottom of the pot body sinks from the center to both sides and forms a water storage area near the edge. The heating element is a heating plate, and the top surface of the heating plate rises from both sides to the center to fit against the bottom of the pot body. With this design, the internal capacity of the pot body is larger, and the lower space of the pot body is larger, which is conducive to processing larger or more voluminous ingredients. Moreover, using a heating plate that matches the shape of the bottom of the pot body as the heating structure ensures the fit between the two and thus ensures the heat transfer effect. The structure of the heating plate is simple and easy to form, which can reduce the processing difficulty and improve the processing efficiency.

[0023] 5. To enhance the secondary heating effect of steam, the bottom wall and side wall of the pot are connected by an arc-shaped corner. At least part of the superheated zone is located in the area where the corner is located, and the water storage area is located inside the superheated zone. During the operation of the air fryer, the hot air generated by the hot air component tends to move along the pot wall. When passing through the corner, the speed slows down, which is conducive to the accumulation of hot air. Thus, the heat of the hot air plus the heat of the superheated zone can double heat the steam in the water storage area, which can increase the temperature of the steam and improve the cooking efficiency and taste of the food.

[0024] 6. The heating element can be formed by setting a heating tube on an aluminum heat-conducting plate. Under the premise of ensuring the heating effect of the heating element on the water storage area and the overheating area, the structure of the heating element can be simplified by using a single-ring heating tube and setting it between the water storage area and the overheating area, which is conducive to reducing costs.

[0025] 7. The heating element can be formed by setting heating tubes on an aluminum heat-conducting plate. In order to accelerate the evaporation of water in the water storage area and increase the temperature of the superheated area to form more high-temperature steam or increase the temperature of the steam, the heating tubes are multi-ringed and respectively set for the water storage area and the superheated area, which can improve the performance of the heating element.

[0026] 8. In order to increase the temperature of the superheated zone to generate more high-temperature steam or to increase the temperature of the steam, the projection of the heating element of the hot air assembly on the bottom of the pot body falls within the range of the superheated zone, so that when the heating element is working, some of its heat can be radiated downward to increase the temperature of the superheated zone, thereby improving the secondary heating effect of the steam.

[0027] 9. In order to ensure the heat transfer efficiency of the heating element to the pot body, an elastic element is provided below the heating element. The elastic element allows the heating element to be attached to the lower surface of the pot body, which can prevent gaps from forming between the heating element and the pot body, thus affecting the heat transfer efficiency and causing some heat loss of the heating element, thereby affecting the steam generation rate and temperature inside the pot, and ensuring the heating effect of steam on the food.

[0042] like Figures 1 to 4 As shown, this application provides an air fryer, including a body 10, a pot body 11 disposed within the body 10, a hot air assembly disposed above the pot body 11, a water replenishment device for adding water to the pot body 11, and a baking tray 20 disposed within the pot body 11. A heating element 12 and a temperature controller 13 are provided on the outer bottom of the pot body 11. An installation area 14 is formed by a recess in the center of the bottom wall of the pot body 11, and the temperature controller 13 is attached to the lower surface of the installation area 14. The pot wall of the pot body 11 below the upper surface of the installation area 14 forms a water storage area 15. An overheating area 16 is provided in the pot wall of the pot body 11 in a region not lower than the upper surface of the installation area 14. Both the water storage area 15 and the overheating area 16 are lower than the baking tray 20. The heating element 12 covers both the water storage area 15 and the overheating area 16. The water replenishment device controls the water level in the water storage area 15 to be below the upper surface of the installation area 14. The water in the water storage area 15 is heated and evaporates to form steam, which is then reheated by the overheating area 16 during its ascent.

[0043] Specifically, when the air fryer is in operation, water is added to the water storage area 15 via a water replenishment device. This device includes, for example, a water storage box and a water pipe connecting the water storage box to the pot body 11. The water storage box can be located on or outside the body 10; this application makes no limitation. Each time water is added to the water storage area 15 according to a pre-set program, the water level does not exceed the highest point of the water storage area 15, thereby controlling the amount of water added. The food to be processed is placed on the baking tray 20, isolated from the water below, to prevent the food from soaking in water and affecting its final taste. When the machine starts working, the hot air assembly blows hot air into the pot 11 to cook the food. Simultaneously, the heating element 12 heats the bottom of the pot 11, and the water storage area 15 and the superheated area 16 gradually heat up. Because the highest water level in the water storage area 15 is lower than the upper surface of the mounting area 14, all the water in the water storage area 15 can be heated to the evaporation temperature, ensuring steam formation. During the steam rise, the superheated area 16 continues to be heated and reheats the steam, so that the steam reaches a higher temperature when it reaches the food surface, improving the heating effect. The temperature controller 13 sets the temperature; for example, when the temperature inside the pot 11 is detected to be greater than 110°C, the heating element 12 stops heating. When the temperature inside the pot 11 drops below 110°C, the heating element 12 continues to operate to continuously generate high-temperature steam.

[0044] The air fryer of this invention simplifies the structural configuration and reduces component costs by setting a single heating element 12 at the bottom of the pot body 11 to achieve secondary steam heating. By limiting the water level in the water storage area 15, it can be ensured that the water in the water storage area 15 is completely evaporated to form steam. Moreover, since the heating element 12 covers both the water storage area 15 and the superheated area 16, the steam can be reheated by the superheated area 16 during its ascent, which can effectively increase the steam temperature, thereby improving the heating effect of the steam on the food and improving the taste of the food.

[0045] It is understandable that during the rising process of steam, due to the difference in the heating time of the steam by the superheated zone 16, at least part of the steam is heated to a higher temperature than the original steam temperature after secondary heating, and the secondary heating of other steam can compensate for the temperature drop of the steam. Overall, it can slow down the rate of steam temperature drop, so that the steam has a higher temperature when it comes into contact with the food, thereby improving the heating effect of the food.

[0046] In a preferred embodiment, the water storage area 15 and the superheated area 16 are arranged adjacent to each other.

[0047] like Figure 1 or Figure 3As shown, the water storage area 15 and the superheated area 16 are arranged adjacent to each other, which allows the steam closer to the superheated area 16 to be reheated faster and at a higher temperature, which is beneficial to improve heat utilization and increase the amount of high-temperature steam generated, thereby improving the heating effect on food. Moreover, it is beneficial to reduce the radial dimension of the heating element 12, further saving material costs.

[0048] In a preferred embodiment, the area of ​​the superheated zone 16 is larger than the area of ​​the water storage zone 15.

[0049] By setting a larger superheated zone 16, more heat can be generated in the superheated zone 16 and the heat can cover a larger area, thereby fully heating the rising steam, further slowing down the rate of steam temperature drop, and improving the effect of steam on food.

[0050] When the water storage area 15 and the superheated area 16 are set adjacent to each other, their positions can be flexibly set, and any of the following methods can be adopted.

[0051] In the first implementation, such as Figure 3 As shown, the hot air assembly includes a centrifugal fan 17 and a water storage area 15 located outside the superheated area 16.

[0052] Understandably, the hot air generated by the hot air assembly moves downward along the side wall of the pot body 11 under the action of the centrifugal fan 17. In order to improve the secondary heating effect of the steam, when the water storage area 15 is located outside the superheated area 16, the water storage area 15 is closer to the side wall of the pot body 11. After the water storage area 15 generates steam, the steam can be heated on both sides by the hot air blown down from above and the heat from the superheated area 16. This not only achieves sufficient secondary heating, but also increases the temperature of the steam, which is beneficial to improving the cooking efficiency and taste of the food.

[0053] In one embodiment, the bottom of the pot body 11 sinks from the center to both sides and forms a water storage area 15 near the edge. The heating element 12 is a heating plate, and the top surface of the heating plate increases from both sides to the center to fit the bottom of the pot body 11.

[0054] In this embodiment, the bottom of the pot body 11 and the heating element 12 have relatively flat shapes. The pot body 11 has a large internal capacity and a large space at the bottom, which is conducive to processing larger or more voluminous ingredients. Moreover, a heating plate that matches the shape of the bottom of the pot body 11 is used as the heating structure. Under the premise of ensuring the fit between the two to ensure the heat transfer effect, the heating plate adopts an integrated structure, which is simple and easy to form, reducing the processing difficulty and improving the processing efficiency.

[0055] In the second embodiment, the bottom wall and side wall of the pot body 11 are connected by an arc-shaped corner 19, at least part of the superheated zone 16 is located in the area where the corner 19 is located, and the water storage zone 15 is located inside the superheated zone 16.

[0056] like Figure 1 As shown, during the operation of the air fryer, the hot air generated by the hot air component tends to move along the pot wall. When it passes the corner 19, the speed slows down, which is conducive to the accumulation of hot air. Thus, the heat of the hot air plus the heat of the superheated zone 16 can double heat the steam in the water storage zone 15, which can increase the temperature of the steam and improve the cooking efficiency and taste of the food.

[0057] In this embodiment, such as Figure 2 As shown, the heating element 12 extends in an arc shape from the bottom to both sides to match the shape of the pot body 11, so that the two fit together better and ensure the heat transfer effect. The heating element 12 covers the bottom wall of the pot body 11 and at least part of the corners 19. When the coverage area of ​​the heating element 12 is large, the superheated zone 16 can be formed in the area where the corners 19 and the side walls are located, which helps to expand the range of the superheated zone 16 and optimize the secondary heating effect of the superheated zone 16 on the steam.

[0058] Based on the above embodiments, the heating element 12 of this application can adopt an integrated structure such as a heating plate, or it can adopt a structure in which a heating tube 122 is provided on an aluminum heat-conducting plate 121, depending on actual needs.

[0059] When the heating element 12 includes an aluminum heat-conducting plate 121 and heating tubes 122 disposed on the aluminum heat-conducting plate 121, the number and position of the heating tubes 122 are set more flexibly, so as to provide a more suitable heating scheme according to the different distribution patterns of the water storage area 15 and the superheated area 16, and improve the heating effect.

[0060] In one embodiment, the heating element 12 includes an aluminum heat-conducting plate 121 and a heating tube 122 disposed on the aluminum heat-conducting plate 121. The heating tube 122 is a single-ring ring and is disposed between the water storage area 15 and the overheating area 16.

[0061] like Figure 1 As shown, under the premise of ensuring the heating effect of the heating element 12 on the water storage area 15 and the superheated area 16, a single-turn heating tube 122 is used. The number of heating tubes 122 is small, which can simplify the structure of the heating element 12 and help reduce costs.

[0062] In another embodiment, the heating element 12 includes an aluminum heat-conducting plate 121 and a heating tube 122 disposed on the aluminum heat-conducting plate 121. The heating tube 122 is a multi-ring shape and is respectively disposed in the water storage area 15 and the overheating area 16.

[0063] like Figure 3As shown, the heating element 122 has at least two coils and is respectively set for the water storage area 15 and the superheated area 16. By concentrating heat to heat the water storage area 15 and the superheated area 16, the evaporation of water in the water storage area 15 can be accelerated, and the temperature of the superheated area 16 can be increased to form more high-temperature steam or increase the temperature of the steam, thereby improving the heating effect of the steam on the food.

[0064] In a preferred embodiment, the hot air assembly includes a heating element 18 and a centrifugal fan 17, with the projection of the heating element 18 onto the bottom of the pot body 11 falling within the superheated zone 16.

[0065] like Figure 1 or Figure 3 As shown, when the heating element 18 is working, some of its heat can radiate downwards to increase the temperature of the superheated zone 16, so as to form more high-temperature steam or increase the temperature of the steam, thereby improving the secondary heating effect of the steam.

[0066] In a preferred embodiment, an elastic element 21 is provided below the heating element 12, and the elastic element 21 causes the heating element 12 to be attached to the lower surface of the pot body 11.

[0067] like Figure 3 As shown, the deformation of the elastic element 21 can always press against the heating element 12 against the lower surface of the pot body 11, which can prevent the formation of gaps between the heating element 12 and the pot body 11, thus affecting the heat transfer efficiency and causing some heat loss of the heating element 12, thereby affecting the steam generation rate and temperature inside the pot body 11, and ensuring the heating effect of steam on the food.

[0068] like Figure 2 or Figure 4 As shown, the heating element 12 has a clearance opening 123 at its center so that the upper end of the thermostat 13 can pass through the clearance opening 123 and be attached to the lower surface of the mounting area 14. Preferably, the thermostat 13 is also abutted by an elastic element. The elastic element acting on the heating element 12 and the elastic element acting on the thermostat 13 can be the same structural element or different structural elements, depending on the needs, to ensure the heat transfer effect of the heating element 12 to the pot body 11 and the temperature detection effect of the thermostat 13.

[0069] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
