Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to an air fryer. Background Art

[0002] An air fryer is a kitchen appliance that uses a heating element and the circulating airflow it generates to cook food. Existing air fryers typically consist of a head and a fryer body. The head is equipped with components such as a heating tube and a fan. The fryer body has a processing chamber for holding the food. The fan delivers air to the heating tube, where it is heated to a preset temperature. The fan then circulates the heated air back into the processing chamber, evenly heating the food inside.

[0003] In the prior art, in order to prevent the heating tube in the machine head from shaking and shifting during the transportation of the air fryer, thereby affecting the use effect of the air fryer, a heating tube fixing structure is usually provided to fix and support the heating tube. For example, the prior art CN202322907211.0 discloses a quick-detachable heating tube fixing device, which includes a heat insulation cover and a fixing frame. The fixing frame includes a connecting portion connected to the heat insulation cover and a fixing portion for fixing the heating tube. The fixing portion is provided with at least one fixing ring formed by bending an elastic sheet and used to fix to the outside of the heating tube. Although the setting of the fixing ring in the above scheme can play a role in vertically limiting the heating tube, due to the lack of effective horizontal limit between the fixing ring and the heating tube, there is still a risk of horizontal shaking of the heating tube during actual product transportation. Utility Model Content

[0035] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0037] To prevent the heating tube inside the air fryer from shaking and shifting during transportation, which would affect the air fryer's performance, existing air fryers typically have a heating tube fixing structure to support the heating tube. Furthermore, multiple heating tube fixing structures are often used to ensure the tube's securement. However, existing heating tube fixing structures primarily serve to limit the vertical position of the heating tube, lacking effective horizontal positioning between the heating tube fixing structure and the heating tube. This creates the risk of the heating tube shaking horizontally during transportation. Furthermore, the multiple heating tube fixing structures also introduce technical issues such as low production efficiency and the large amount of space occupied by the reflector. In severe cases, these fixing structures can even interfere with the air fryer's fan blades, producing unusual noise.

[0038] In view of the above problems, this embodiment provides an air fryer. Figure 1-3 As shown, Figure 1 This is a schematic diagram of the three-dimensional structure of the air fryer after the reflector cover 1, the heating tube 3 and the fixing bracket 4 are assembled; Figure 2 This is a bottom view of the air fryer of this embodiment after the reflector cover 1, the heating tube 3 and the fixing bracket 4 are assembled; Figure 3 This is a side view of the assembled reflector 1, heating tube 3, and fixing bracket 4 of the air fryer of this embodiment. The air fryer of this embodiment includes a body, within which are disposed the reflector 1, fan blades 2, heating tube 3, and fixing bracket 4. The reflector 1, fan blades 2, and heating tube 3 are arranged in order from top to bottom. It should be noted that "from top to bottom" in this embodiment refers to the direction from the top to the bottom of the air fryer.

[0039] For example, the heating tube 3 of this embodiment adopts a spiral distribution structure, such as Figure 2 、 Figure 4 and Figure 5 As shown, Figure 4 is a schematic structural diagram of the heating tube 3 of this embodiment, Figure 5 FIG2 is a schematic diagram of the structure of the reflector 1 of this embodiment. In this embodiment, the two ends of the heating tube 3 are arranged close to each other and are mounted on the reflector 1 via flanges 5. Specifically, the reflector 1 may be provided with flange mounting portions 11, and the flanges 5 are fixed to the two ends of the heating tube 3 and fixed to the flange mounting portions 11 via fasteners such as screws.

[0040] In this embodiment, a limiting structure is provided on the outer surface of the heating tube 3, and the fixing bracket 4 cooperates with the limiting structure to limit the horizontal and vertical directions of the heating tube 3. Figure 4 As shown, the limiting structure can be a slot 31 and a convex bump 32 formed on the heating tube 3, wherein the slot 31 can cooperate with the fixing bracket 4 to realize the limiting of the heating tube 3 in the vertical direction, and the convex bump 32 can cooperate with the fixing bracket 4 to realize the limiting of the heating tube 3 in the horizontal direction.

[0041] Preferably, the slot 31 and the bulge 32 can be formed by partially bending the heating tube 3. In this case, the slot 31 and the bulge 32 opposite to the slot 31 are simultaneously formed on the outer surface of the heating tube 3. By directly bending the heating tube 3 to form the slot 31 and the bulge 32, the structure of the heating tube 3 and the structure of the fixing bracket 4 are simplified.

[0042] Of course, it is understandable that in other embodiments, the above-mentioned groove 31 and convex bump 32 can also adopt other structures. For example, two protrusions can extend outward from the outer surface of the heating tube 3, and the groove 31 is formed between the two protrusions. The outer side walls of the two protrusions constitute the above-mentioned convex bump 32.

[0043] Preferably, the heating tube 3 of this embodiment includes a first tube section 33 located at the outermost side, and the aforementioned slot 31 and protrusion 32 are formed on the first tube section 33. Furthermore, the fixing bracket 4 cooperating therewith can be installed at the outermost side of the heating tube 3 without affecting or interfering with the heating tube 3 and the fan blades 2.

[0044] The fan blades 2 are installed between the reflective cover 1 and the heating tube 3 to transport the air heated by the heating tube 3 into the pot body of the air fryer to process the food.

[0045] In this embodiment, in order to fix the heating tube 3, the above-mentioned fixing bracket 4 is fixedly installed on the reflector 1, and the heating tube 3 is limited in the horizontal and vertical directions by the fixing bracket 4. For example, the structure of the fixing bracket 4 is as follows: Figure 6 As shown, the fixing bracket 4 includes a base 41 and a limiting portion 42 . Preferably, the limiting portion 42 and the base 41 are integrally formed.

[0046] The base 41 is fixedly mounted on the lower surface of the reflector 1, for example, the reflector 1 may be provided with an upwardly concave mounting groove 12 ( Figure 5 As shown in FIG4 , the base 41 is placed in the mounting groove 12. Specifically, a fastener can be passed through the reflector 1 and fixed to the base 41 to fix the base 41 and the reflector 1. Furthermore, in this embodiment, a limiting hole 13 can be provided on the side wall of the mounting groove 12, and a corresponding claw 411 is provided on the base 41. When installing the fixing bracket 4, the claw 411 of the base 41 is first engaged with the limiting hole 13 to achieve the positioning of the base 41 in the mounting groove 12. Subsequently, a fastener is passed through the through hole on the reflector 1 and fixed to the base 41 to achieve the installation and fixation of the base 41 and the reflector 1. Preferably, two limiting holes 13 and two claws 411 can be provided to improve the positioning effect of the base 41.

[0047] The limiting portion 42 of this embodiment is connected to the outer surface of the heating tube 3 to limit the movement of the heating tube 3 in the vertical direction, and the limiting portion 42 cooperates with the limiting structure to limit the movement of the heating tube 3 in the horizontal direction.

[0048] Alternatively, as Figure 6 As shown, the limiting portion 42 includes a first limiting structure 421 and a second limiting structure 422, both of which are connected to the base 41, wherein the first limiting structure 421 can be snapped into the slot 31, thereby limiting the vertical position of the heating tube 3, so that the heating tube 3 cannot move in the vertical direction. The second limiting structure 422 abuts against both sides of the convex 32 in the horizontal direction, and then through the cooperation between the convex 32 and the second limiting structure 422, the movement of the heating tube 3 in the horizontal direction is restricted. It should be noted that in this embodiment, the first limiting structure 421 is preferably snapped into the slot 31, while the second limiting structure 422 abuts against both sides of the convex 32 in the horizontal direction. In other embodiments, the first limiting structure 421 may be snapped into other parts of the heating tube 3, and the second limiting structure 422 abuts against both sides of the convex 32 in the horizontal direction.

[0049] For example, the first limiting structure 421 of this embodiment includes a first support plate 4211 and a hook, wherein the first support plate 4211 is connected to the base 41, the hook is connected to the end of the first support plate 4211 that is not connected to the base 41, the opening of the slot 31 is downward, the hook extends downward from the reflector 1 to the heating tube 3, and is bent and connected to the slot 31 to achieve vertical positioning of the heating tube 3. Furthermore, the outer walls of the hook of this embodiment can also abut against the inner walls of the slot 31. While achieving vertical positioning of the heating tube 3, it can also limit the horizontal movement of the heating tube 3. At this time, the abutment structure of the convex bump 32 and the second limiting structure 422 is combined to achieve a better horizontal positioning effect of the heating tube 3.

[0050] Preferably, the depth of the above-mentioned groove 31 can be 1mm-3mm, so as to facilitate the formation of the groove 31 on the heating tube 3 on the basis of being able to realize the hook connection without causing damage to the heating tube 3.

[0051] The second limiting structure 422 includes two second support plates 4221 connected to the base 41 and arranged opposite each other. A downwardly facing positioning groove 4222 is formed at one end of the second support plate 4221 not connected to the base 41. The heating tube 3 is inserted into the positioning groove 4222, and the protrusion 32 formed on the heating tube 3 abuts against the opposing side walls of the two second support plates 4221. In other words, by providing the positioning groove 4222 to insert the heating tube 3 and abutting the protrusion 32 against the side walls of the two second support plates 4221, the horizontal position of the heating tube 3 can be limited. Preferably, the positioning groove 4222 is a semicircular open groove, and the diameter of the positioning groove 4222 is not less than the diameter of the heating tube 3, and is preferably equal to the diameter of the heating tube 3. Therefore, when the heating tube 3 is installed, half of the heating tube 3 is stuck in the positioning groove 4222, which is convenient for the assembly and fixation of the heating tube 3, and can also fix the position of the heating tube 3 and the distance from the temperature sensor 6 of the air fryer, thereby improving the detection accuracy and stability of the temperature sensor 6.

[0052] Exemplarily, the spacing length of the positioning grooves 4222 of the two second support plates 4221 is L, and the value of L is preferably 20-30 mm, more preferably 25-30 mm, so that the two second support plates 4221 and the flanges 5 form a three-point support for the heating tube 3 to avoid the situation where the two sides of the heating tube 3 shake up and down due to only one fixed bracket 4.

[0053] It should be noted that the height of the second support plate 4221 should be set to ensure that the heating tube 3 is in a horizontal state after being inserted into the positioning groove 4222 , and will not affect the connection between the flange 5 and the reflector 1 .

[0054] Preferably, if Figure 6 As shown, the two second support plates 4221 and the first support plate 4211 are integrally formed. For example, the two ends of the first support plate 4211 can be bent relative to each other to form two second support plates 4221. At this time, the two second support plates 4221 and the first support plate 4211 are arranged in a triangle, which on the one hand improves the connection stability between the fixed bracket 4 and the heating tube 3, and on the other hand also improves the overall structural strength of the fixed bracket 4.

[0055] In a preferred embodiment, the heating tube 3 further includes a second tube section 34 located on the outside, and the first tube section 33 and the second tube section 34 are arranged in sequence from the outside to the inside along the radial direction. Correspondingly, the above-mentioned limiting portion 42 includes a first hook 4212 and a second hook 4213, wherein the first hook 4212 is hooked in the slot 31 of the first tube section 33 ( Figure 7As shown, the second hook 4213 is hooked on the second pipe section 34. In this case, the second pipe section 34 may be provided with a slot 31 or not. When the slot 31 is not provided, the second hook 4213 is bent and wrapped around the second pipe section 34 to achieve fixation with the second pipe section 34. In this case, the first hook 4212 and the second hook 4213 jointly limit the vertical position of the heating pipe 3. Of course, it is understandable that the first hook 4212 can also be hooked on the first pipe section 33 when the first pipe section 33 is not provided with a slot 31.

[0056] Preferably, the fixing bracket 4 and the flange 5 of this embodiment are arranged oppositely on both sides of the center of the reflector 1. Through the arrangement of this structure, the fixing points of the heating tube 3 on the reflector 1 can be arranged oppositely, which is conducive to the stable fixation of the heating tube 3 on the reflector 1.

[0057] The above-mentioned air fryer of this embodiment can limit the heating tube 3 in the horizontal and vertical directions through the cooperation of the fixed bracket 4 and the heating tube 3, thereby effectively preventing the heating tube of the air fryer from shaking during transportation and causing damage. Moreover, only one fixed bracket 4 is needed to limit the heating tube 3 in the vertical and horizontal directions, without the need for too many fixed brackets 4, thereby improving the assembly efficiency and effectively reducing the overall cost of the air fryer. Moreover, the provision of only one fixed bracket 4 can also avoid interference between the fixed bracket 4 and the fan blade 2, thereby avoiding the generation of abnormal noise caused by the fixed bracket 4, and improving the user experience. Of course, from the perspective of reliable fixation, multiple fixed brackets can also be provided, and the number of fixed brackets is not specifically limited.

[0058] It is understandable that the limiting structure can also adopt other forms. In the above embodiment, the limiting structure includes both the slot 31 and the convex bulge 32. In other implementations, the limiting structure can also include only the slot 31 or only the convex bulge 32, or adopt other forms.

[0059] In the present application, the limiting structure is preferably formed by local bending of the heating tube 3 or local change in the tube diameter. For example, the heating tube 3 is locally bent, and a groove 31 and a bulge 32 for interacting with the limiting portion 42 can be formed at the bending portion; for example, the local tube diameter of the heating tube 3 can be changed, and the local tube diameter can be reduced to form a groove 31, and the local tube diameter can be increased to form a bulge 32. The groove 31 and the bulge 32 can serve as limiting structures that cooperate with the limiting portion 42.
