Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, and in particular to an air fryer. Background Art

[0002] An air fryer uses rapidly circulating hot air to heat ingredients, achieving the texture and feel of deep-fried food. To address the issue of insufficient heating underneath the ingredients due to the stacked ingredients blocking the hot air circulation, a bottom heating structure is typically installed at the bottom of the air fryer. However, when the user removes or places the inner pot, the bottom of the pot can easily scrape against the bottom heating structure. Consequently, after prolonged use, the bottom of the pot and the upper surface of the bottom heating structure can become damaged, affecting the heat transfer efficiency of the inner pot. Utility Model Content

[0003] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0004] To this end, the utility model proposes an air fryer, which can avoid the problem of scratching between the bottom of the inner pot and the bottom heating component, and is conducive to ensuring the heat transfer effect of the air fryer.

[0005] The air fryer of the present invention comprises: a casing, a cooking cavity is provided in the casing, and the casing has a bottom plate; a bottom heating assembly, the bottom heating assembly comprises a heating element and a heat transfer cover plate, the heat transfer cover plate is arranged on the upper side of the bottom plate, and the heating element is arranged between the heat transfer cover plate and the heating element; an inner pot, the inner pot is detachably installed in the cooking cavity, and the bottom of the inner pot is spaced apart from the bottom heating assembly in the upper and lower directions.

[0006] The air fryer of the present invention, with a bottom heating assembly installed on the bottom plate, heats the bottom surface of the food, compensating for the problem of stacked ingredients blocking the original hot air circulation, resulting in insufficient heating and inadequate browning of the food underneath. Because the inner pot is retractable within the cooking chamber, and the bottom of the inner pot is vertically separated from the bottom heating assembly, friction and scratches between the inner pot and the bottom heating assembly are prevented when the inner pot is pulled out, thus avoiding scratches on the bottom of the inner pot and the upper surface of the bottom heating assembly. This ensures the air fryer's aesthetically pleasing appearance while preventing adverse effects on the heat transfer.

[0007] Optionally, a gap H1 is defined between the heat transfer cover plate and the bottom plate and the bottom of the inner pot, where 0.2 mm ≤ H1 ≤ 5 mm. By setting the gap H1 within the aforementioned range, the air fryer of the present invention protects the bottom of the inner pot, the heat transfer cover plate, and the bottom plate from scratches, reduces the axial space occupied by the air fryer, and ensures effective heat transfer from the heat transfer cover plate to the inner pot.

[0008] Optionally, the air fryer further comprises two slide rails, which are mounted on the bottom plate and respectively arranged on either side of the heat transfer cover plate. The slide rails extend along the direction in which the inner pot is pulled out and abut against the bottom of the inner pot. The air fryer of the present invention provides two slide rails on the bottom plate, and the slide rails are arranged on either side of the heat transfer cover plate. This eliminates the need to occupy space on the heat transfer cover plate, which is beneficial for improving the heat transfer efficiency of the heat transfer cover plate. Furthermore, the inner pot is slidably supported by the two slide rails, which reduces the contact area between the bottom of the inner pot and the slide rails and ensures the stability of the inner pot when it is pulled out.

[0009] Optionally, the base plate is provided with a mounting hole, and the slide rail includes a connected main body and a slide bar portion, wherein the main body portion is detachably mounted on the lower side of the base plate, the slide bar portion passes through the mounting hole and protrudes from the cooking cavity, and the slide bar portion extends along the direction in which the inner pot is pulled out and abuts against the bottom of the inner pot. The air fryer of the present invention connects the base plate and the slide rail in a detachable manner, allowing the base plate and the slide rail to be processed and manufactured separately, and the assembly method is simple. In addition, since the slide bar portion passes through the mounting hole and protrudes from the cooking cavity, the appearance of the bottom surface of the cooking cavity can be simplified, thereby improving the integrity and aesthetics of the air fryer.

[0010] Optionally, the slide rail further includes a wire-locking portion connected to the main body and located on the underside of the base plate. The wire-locking portion has a slot, and the heating element includes a control wire, which is secured within the slot. The air fryer of this invention secures the control wire within the slot of the slide rail, thereby improving the electrical safety of the air fryer. Furthermore, since the wire-locking portion is integrated into the slide rail, the structure of the slide rail can be fully utilized, reducing production costs.

[0011] Optionally, the front side of the cooking cavity is provided with an opening for placing the inner pot in and out, the slide rail extends in the front-to-back direction of the housing, and the front end of the slide rail is provided with a guide slope that gradually slopes upward from the front to the back. The air fryer of the present invention, by providing the guide slope, can guide the inner pot when it is pushed into the cooking cavity, thereby preventing the inner pot from colliding with the front end of the slide rail and becoming stuck.

[0012] Optionally, a receiving groove is provided on the upper side of the bottom plate, and the receiving groove and the heat transfer cover plate together form an installation cavity, and the heating element is disposed in the installation cavity and is in contact with the heat transfer cover plate. By providing the receiving groove on the upper side of the bottom plate, the air fryer of the present invention can reduce the space occupied by the heating element and the heat transfer cover plate in the cooking cavity, making the structure more compact.

[0013] Optionally, the upper end surface of the bottom plate is flush with the upper end surface of the heat transfer cover plate. The air fryer of the present invention makes the bottom surface of the cooking cavity flat by aligning the upper end surface of the bottom plate with the upper end surface of the heat transfer cover plate, thereby improving the integrity and aesthetics of the air fryer and facilitating daily cleaning by the user.

[0014] Optionally, the air fryer further includes a frying basket, which is placed on the inner pot, with a gap H2 between the frying basket and the bottom wall of the inner pot, where 2mm≤H2≤12mm. By ensuring that the frying basket and the bottom wall of the inner pot are within this gap range, the air fryer of the present invention facilitates the user's removal of the frying basket from the inner pot and reduces the likelihood of food being soaked in oozing grease during cooking.

[0015] Optionally, the bottom wall of the inner pot is provided with a plurality of ribs, which are spaced apart and extend in a predetermined direction. The air fryer of the present invention, by providing the ribs, allows food to be placed directly on the bottom wall of the inner pot, allowing both the upper and lower surfaces of the food to be heated simultaneously, thereby improving heat transfer.

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] Please refer to the following Figures 1 to 8 An air fryer according to an embodiment of the present invention is described.

[0033] like Figures 1 to 4 As shown, the air fryer of the present invention comprises a housing 1, a bottom heating assembly 2, and an inner pot 3. The housing 1 defines a cooking cavity 11, which has a bottom plate 12. The bottom heating assembly 2 comprises a heating element 21 and a heat transfer cover 22, which is disposed above the bottom plate 12. The heating element 21 is disposed between the heat transfer cover 22 and the heating element 21. The inner pot 3 is retractably mounted within the cooking cavity 11, with the bottom 32 of the inner pot 3 vertically spaced apart from the bottom heating assembly 2.

[0034] According to the air fryer of the embodiment of the present invention, by disposing a bottom heating assembly 2 on the bottom plate 12, the bottom surface of the food can be heated, thereby compensating for the problem of insufficient heating and browning caused by stacked ingredients blocking the original hot air circulation. Because the inner pot 3 is retractably mounted in the cooking cavity 11, and the bottom 32 of the inner pot 3 is vertically separated from the bottom heating assembly 2, friction and scratches between the inner pot 3 and the bottom heating assembly 2 are prevented when the inner pot 3 is pulled out, thus avoiding scratches on the bottom 32 of the inner pot 3 and the upper surface of the bottom heating assembly 2. This ensures the aesthetic appearance of the air fryer while avoiding adverse effects on the heat transfer effect of the air fryer.

[0035] It is understandable that when scratches appear on the bottom 32, heat transfer cover 22, and bottom plate 12 of the inner pot 3, there will be a difference in the heat transfer effect at the scratched location and the heat transfer effect at the normal wall surface (non-scratched location). This can lead to uneven heating of the food in the inner pot 3. However, the air fryer of the embodiment of the present invention can avoid scratches on the bottom 32 of the inner pot 3 and the bottom heating assembly 2 by separating the bottom 32 of the inner pot 3 from the bottom heating assembly 2 in the vertical direction. On the other hand, by providing a small heat transfer gap between the bottom 32 of the inner pot 3 and the bottom heating assembly 2, the uniformity of the heating of the inner pot 3 can be improved.

[0036] Specifically, the air fryer further includes a top heating assembly (not shown), which is disposed within the housing 1 and above the cooking cavity 11. The top heating assembly and the bottom heating assembly 2 can heat together, forming a three-dimensional heating structure in the air fryer, thereby improving the cooking effect of the air fryer and compensating for the problem that the stacked ingredients block the original hot air circulation, resulting in insufficient heating and insufficient browning of the ingredients.

[0037] The inner pot 3 can be pulled out in a horizontal direction. For example, the inner pot 3 can be pulled out in a left-right direction of the housing 1. For another example, the inner pot 3 can be pulled out in a front-back direction of the housing 1.

[0038] like Figure 1 As shown, in an example of the present invention, an opening 13 for taking out and placing the inner pot 3 is provided on the front side of the cooking cavity 11 , and the inner pot 3 can be pulled out along the front-to-back direction of the casing 1 .

[0039] Alternatively, as Figure 6 As shown, a gap H1 is formed between the heat transfer cover plate 22 and the bottom plate 12 and the bottom 32 of the inner pot 3, where 0.2 mm ≤ H1 ≤ 5 mm. For example, the value of H1 can be 0.2 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm. Preferably, the value of H1 is 2 mm.

[0040] Through experimental research, the inventors of the present invention have discovered that when gap H1 is too large (greater than 5 mm), the heat transferred from the heat transfer cover plate 22 to the inner pot 3 is significantly reduced, affecting the heat transfer efficiency of the bottom heating assembly 2. Furthermore, it occupies a significant amount of axial space within the cooking cavity 11, reducing the storage capacity within the cooking cavity 11. When gap H1 is too small (less than 0.2 mm), due to certain deviations during assembly of the air fryer, the bottom 32 of the inner pot 3, the heat transfer cover plate 22, and the bottom plate 12 may still be scratched.

[0041] Therefore, the air fryer of the embodiment of the present invention adopts the above-mentioned range for the gap H1, which can not only ensure that the bottom 32 of the inner pot 3, the heat transfer cover 22 and the bottom plate 12 are not scratched, but also reduce the axial space occupied by the air fryer and ensure the heat transfer effect of the heat transfer cover 22 to the inner pot 3.

[0042] In some embodiments, as Figures 2 to 4 As shown, the air fryer further comprises two slide rails 4, which are mounted on the bottom plate 12 and are respectively arranged on both sides of the heat transfer cover plate 22. The slide rails 4 extend along the pulling direction of the inner pot 3 (as shown in FIG. Figure 1 The air fryer of the present invention has two slide rails 4 disposed on the bottom plate 12, and the slide rails 4 are arranged on both sides of the heat transfer cover plate 22. This eliminates the need to occupy space on the heat transfer cover plate 22, thereby improving the heat transfer efficiency of the heat transfer cover plate 22. Furthermore, the two slide rails 4 slidably support the inner pot 3, reducing the contact area between the bottom 32 of the inner pot 3 and the slide rails 4, and ensuring the stability of the inner pot 3 when it is pulled out.

[0043] In other examples, the two slide rails 4 may also be fixedly mounted on the pot bottom 32 of the inner pot 3 , and the two slide rails 4 are slidably engaged with the bottom plate 12 .

[0044] Alternatively, as Figure 4 and Figure 5 As shown, the bottom plate 12 is provided with a mounting hole 121, and the slide rail 4 includes a main body portion 41 and a slide portion 42 connected to each other. The main body portion 41 is detachably mounted on the lower side of the bottom plate 12, and the slide portion 42 passes through the mounting hole 121 and protrudes from the cooking cavity 11. The slide portion 42 is arranged along the pulling direction of the inner pot 3 (as shown in FIG. Figure 1 The mounting hole 121 extends in the front-to-back direction of the housing 1 and abuts the bottom 32 of the inner pot 3. It should be understood that the mounting hole 121 is a strip-shaped hole that extends in the front-to-back direction of the housing 1 and extends vertically through the bottom plate 12. When installing the slide rail 4, the operator aligns the slide bar 42 from bottom to top and inserts it into the mounting hole 121. The main body 41 is fixed to the lower end surface of the bottom plate 12, and the slide bar 42 protrudes from the cooking cavity 11 to support the bottom 32 of the inner pot 3.

[0045] The air fryer of the present invention utilizes a detachable connection between the bottom plate 12 and the slide rails 4, allowing for separate fabrication and assembly. Furthermore, since the slide bar 42 extends through the mounting hole 121 and protrudes from the cooking cavity 11, the bottom surface of the cooking cavity 11 is streamlined, enhancing the overall appearance and aesthetics of the air fryer.

[0046] For example, Figure 5 As shown, the slide rail 4 further includes an ear seat 44 , and a screw member is provided through the ear seat 44 and the base plate 12 to fix the slide rail 4 on the base plate 12 , thereby improving the firmness of the installation of the slide rail 4 .

[0047] In other examples, the main body 41 of the slide rail 4 may be fixed to the base plate 12 via a snap-fit ​​structure.

[0048] Alternatively, as Figure 5 and Figure 6 As shown, the slide rail 4 also includes a wire-locking portion 43, which is connected to the main body 41 and located on the lower side of the base plate 12. The wire-locking portion 43 has a slot 431. The heating element 21 has a control wire, which is locked in the slot 431. The air fryer of this embodiment of the utility model secures the control wire in the slot 431 of the slide rail 4, thereby improving the electrical safety of the air fryer. Furthermore, since the wire-locking portion 43 is integrated into the slide rail 4, the structure of the slide rail 4 can be fully utilized, reducing production costs.

[0049] In the example of the present application, the wire clamping portion 43 and the ear seat 44 are both one, and are arranged at intervals along the length direction of the slide rail 4, thereby making the overall structure of the slide rail 4 simple and easy to process and manufacture.

[0050] In some embodiments, as Figure 1 and Figure 5 As shown, the front side of the cooking cavity 11 is provided with an opening 13 for placing the inner pot 3 in and out. The slide rail 4 extends along the front-to-back direction of the housing 1. The front end of the slide rail 4 is provided with a guide slope 421, which gradually slopes upward from front to back. The guide slope 421 can be either flat or curved. By providing the guide slope 421, the air fryer of this embodiment of the present invention can guide the inner pot 3 when it is pushed into the cooking cavity 11, thereby preventing the inner pot 3 from colliding with the front end of the slide rail 4 and causing it to become stuck.

[0051] In other words, the height of the front end of the slide rail 4 gradually decreases from the back to the front, and smoothly transitions to the bottom plate 12. Therefore, when the user pushes the inner pot 3 into the cooking cavity 11, the inner pot 3 can move backward under the action of the guide slope 421, thereby preventing the inner pot 3 from colliding with the front end of the slide rail 4 and preventing the inner pot 3 from getting stuck during the insertion process.

[0052] In some embodiments, as Figure 3 As shown, a receiving groove 122 is provided on the upper side of the base plate 12. The receiving groove 122 and the heat transfer cover plate 22 together form an installation cavity. The heating element 21 is disposed within the installation cavity and is in close contact with the heat transfer cover plate 22. By providing the receiving groove 122 on the upper side of the base plate 12, the air fryer of this embodiment of the present invention can reduce the space occupied by the heating element 21 and the heat transfer cover plate 22 in the cooking cavity 11, resulting in a more compact structure. Furthermore, since the heating element 21 is in close contact with the heat transfer cover plate 22, the amount of heat transferred from the heating element 21 to the heat transfer cover plate 22 is increased, thereby improving heat transfer efficiency.

[0053] Alternatively, as Figure 6 As shown, the upper end surface of the bottom plate 12 is flush with the upper end surface of the heat transfer cover plate 22. In the air fryer of the present invention, by aligning the upper end surface of the bottom plate 12 with the upper end surface of the heat transfer cover plate 22, the bottom surface of the cooking cavity 11 is made smooth, thereby improving the integrity and aesthetics of the air fryer and facilitating daily cleaning by the user.

[0054] For example, the heat transfer cover plate 22 may be made of a material with a high thermal conductivity (such as aluminum alloy) to further improve the heat transfer efficiency of the heat transfer cover plate 22. The heat transfer cover plate 22 and the base plate 12 may be connected by riveting studs.

[0055] like Figure 3 As shown, in order to reduce the amount of heat transferred from the heating element 21 to the bottom plate 12, a fixed bracket 23 can be provided between the heating element 21 and the bottom plate 12 so that the upper end surface of the bottom plate 12 is separated from the heating element 21, thereby improving the overall heat transfer efficiency of the bottom heating assembly 2.

[0056] Specifically, the fixing bracket 23 is mounted on the bottom plate 12 via screws, and the heating element 21 is clamped on the fixing bracket 23 to facilitate installation and removal of the heating element 21 .

[0057] like Figure 3 As shown, the heating element 21 is a heating tube, and the outer peripheral contour of the heating tube is arranged in a "concave" shape. The air fryer of the embodiment of the utility model can extend the heating path of the heating tube by setting the heating tube in the above structure, and has a higher heat transfer efficiency.

[0058] In some embodiments, as Figure 6 and Figure 7 As shown, the air fryer further includes a frying basket 5, which is placed on the inner pot 3. A gap H2 is formed between the frying basket 5 and the bottom wall of the inner pot 3, wherein 2mm≤H2≤12mm. For example, H2 can be 2mm, 4mm, 6mm, 8mm, 10mm, or 12mm.

[0059] Through experimental research, the inventors of this application discovered that when H2 is too small (less than 2 mm), the frying basket 5 is too close to the bottom wall of the inner pot 3, making it difficult for the user to remove the frying basket 5 from the inner pot 3. Furthermore, grease produced during cooking accumulates on the bottom wall of the inner pot 3. When the frying basket 5 is too close to the bottom wall of the inner pot 3, the food is easily soaked in grease, resulting in a poor taste after cooking. When H2 is too large (greater than 12 mm), the distance between the food and the heat transfer cover 22 is too great, resulting in poor browning of the bottom surface of the food.

[0060] The air fryer of the embodiment of the present invention adopts the above-mentioned gap range between the frying basket 5 and the bottom wall of the inner pot 3, which can not only facilitate the user to remove the frying basket 5 from the inner pot 3, but also reduce the probability of food being soaked in seeping fat during cooking, and the bottom surface of the food has a better coloring effect.

[0061] Alternatively, as Figure 8 As shown, the bottom wall of the inner pot 3 is provided with a plurality of ribs 31. The ribs 31 are arranged at intervals on the bottom wall of the inner pot 3 and extend in a predetermined direction. By providing the ribs 31, the air fryer of the present embodiment allows food to be placed directly on the bottom wall of the inner pot 3, thereby heating both the upper and lower surfaces of the food simultaneously, which is conducive to improving heat transfer.

[0062] For example, the preset direction may be the front-to-back direction of the inner pot 3 , the left-to-right direction of the inner pot 3 , the circumferential direction or the radial direction of the inner pot 3 , and the present invention does not limit this.

[0063] In some embodiments, as Figure 3 As shown, the bottom heating assembly 2 further includes a temperature control element 6, which is disposed within the mounting cavity and electrically connected to the heating element 21. The temperature control element 6 is used to control the heating power and heating time of the heating element 21. By providing the temperature control element 6, the air fryer of the embodiment of the present invention can control the heating temperature and heating time of the bottom heating assembly 2, thereby improving the cooking effect of the air fryer.
