Description

Technical Field

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

[0002] An air fryer is a kitchen appliance that uses a heating element and the circulating hot air it generates to cook food. Existing air fryers typically incorporate a microswitch to detect whether the fryer is properly positioned, thus improving safety during use. However, to prevent damage to the microswitch due to overheating, prior art CN202222928832.2 discloses an air fryer, as shown in its appendix... Figure 2 As shown, the air fryer includes a shell with an opening for placing the fryer body. Above the opening, from bottom to top, are a mounting bracket, a reflector, a motor bracket, and a micro switch. The motor bracket covers the upper outer side of the reflector, and the micro switch is mounted above the motor bracket. Through this structure, the motor bracket can insulate the heat from the reflector to prevent heat transfer to the micro switch, thus preventing damage to the micro switch due to excessive heating.

[0003] However, in the above structure, the motor bracket is located outside the reflector, resulting in a higher overall cost. Currently, to reduce costs, some air fryers have reduced the size of the motor bracket. In this case, the motor bracket no longer completely encloses the reflector, and the exposed sidewalls of the reflector lead to excessively high temperatures in the upper cavity. The microswitch assembly is directly exposed in the upper cavity of the shell, with no obstruction between the microswitch assembly and the reflector. This causes the microswitch to overheat and become prone to damage. Furthermore, for food safety reasons, the edge of the reflector is extended to the opening, and the fixing bracket is placed above the reflector. This increases the contact area between the reflector and the cooking cavity, resulting in even higher reflector temperatures, which further exacerbates the temperature rise of the microswitch. Utility Model Content

[0004] This application provides an air fryer to solve the technical problem that in existing air fryers with smaller overall motor brackets, the temperature inside the mounting cavity is too high due to partial exposure of the reflector, and the micro switch assembly is easily damaged due to excessive heat rise because there is no obstruction between it and the reflector.

[0005] This application provides an air fryer, including a shell and a pot body. A metal reflector is provided inside the shell, which divides the shell into an upper mounting cavity and a lower cooking cavity. An opening is formed on the side of the cooking cavity for the pot body to enter and exit. A micro switch assembly is provided inside the mounting cavity, and the micro switch assembly includes a micro switch and a fixing base.

[0006] The reflector includes a top wall, side walls extending downward and outward from the edge of the top wall, and a flange extending outward from the edge of the side wall. The side walls are exposed in the mounting cavity, and the flange extends to the opening.

[0007] A plastic fastener is installed on the upper surface of the flange near the opening. The micro switch assembly is mounted on the fastener via the mounting base. The fastener has an upwardly extending first heat insulation plate located between the side wall and the micro switch assembly to isolate the side wall from the micro switch assembly.

[0008] This application, by setting a first heat insulation plate on the fixing component, isolates the side wall of the reflector from the micro switch assembly. This effectively prevents heat from the reflector from being transferred to the micro switch assembly from its side wall, thereby reducing the temperature rise of the micro switch assembly and extending its service life. Furthermore, it is particularly suitable for air fryers with a smaller overall motor bracket, effectively solving the technical problem of excessive temperature rise and easy damage to the micro switch in existing air fryers with a smaller overall motor bracket.

[0009] As a preferred technical solution, the first heat insulation plate is provided with a limiting rib on the side facing the micro switch assembly.

[0010] By setting a limiting rib, a certain distance can be maintained between the micro switch assembly and the first heat insulation plate, ensuring that the micro switch assembly will not come into contact with the first heat insulation plate. This solves the problem that the micro switch assembly may come into contact with the first heat insulation plate when there is a deviation in the installation, which may affect the use of the micro switch assembly.

[0011] As a preferred technical solution, the micro switch assembly is located at a corner near the side wall.

[0012] By placing the micro switch assembly at the corner of the side wall near the reflector, compared to placing it at a non-corner location, the space at the corner of the housing can be used to install the micro switch assembly. Furthermore, the temperature of the reflector at the corner is lower, resulting in less heat transfer and further reducing the impact of the heat from the side wall of the reflector on the micro switch assembly.

[0013] As a preferred technical solution, the flange has a tapered hole with a diameter that gradually decreases from bottom to top, and the screw passes through the tapered hole and the fixing member from bottom to top to fix the reflector to the fixing member.

[0014] As a preferred technical solution, the screw includes a nut at one end, and the slope of the sidewall of the nut is greater than the slope of the wall of the tapered hole.

[0015] This design ensures that the nut and the tapered hole are in line contact, thereby reducing the heat transferred from the reflector to the screw, lowering the screw temperature, and preventing the screw from overheating and causing carbonization of the connected plastic parts, which could lead to the screw falling off.

[0016] As a preferred technical solution, the fastener is provided with a first fixing part, which is fixedly connected to the flange by fasteners, and the first heat insulation plate is separated between the first fixing part and the side wall.

[0017] As a preferred technical solution, the fastener is provided with an upwardly extending second heat insulation plate, and the fastener is provided with a second fixing part, the second fixing part being fixedly connected to the flange by fasteners, and the second heat insulation plate being separated between the second fixing part and the side wall.

[0018] As a preferred technical solution, the flange has a step near the opening, and the pot body abuts against the step.

[0019] By incorporating a step in the reflector, the pot body rests against the step when it enters the cooking chamber. This contact prevents hot air from escaping between the pot body and the reflector, reducing heat loss and improving the pot's thermal efficiency in baking food. Furthermore, it prevents the pot handle from overheating due to hot air, thus avoiding a negative user experience.

[0020] As a preferred technical solution, the step includes a first plate extending horizontally inward from the opening and a second plate extending downward at the inner end of the first plate, with the pot body abutting against the second plate.

[0021] On the one hand, the pot body abuts against the second plate, and the contact between the two effectively prevents hot air from escaping from the pot body. On the other hand, the bent structure formed between the first plate and the second plate can block the escape of hot air, achieving a good sealing effect, preventing heat loss, and at the same time preventing hot air from damaging the shell which is not resistant to high temperatures, thus avoiding the phenomenon of the shell melting.

[0022] As a preferred technical solution, the vertical height of the second plate is greater than or equal to 1 mm.

[0023] The vertical height is set to be greater than or equal to 1mm. The higher the vertical height of the second plate, the lower the probability that hot air will escape to the outside through the gap between the pot body and the second plate. Attached Figure Description

[0035] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0037] Some existing air fryers have made the motor bracket smaller. In this case, the motor bracket no longer completely covers the reflector, so the micro switch component is directly exposed in the upper cavity of the shell. The temperature in the upper cavity is high and there is no barrier between the micro switch component and the reflector, which causes the micro switch to overheat and become easily damaged.

[0038] Based on the above problems, this application provides an air fryer, such as... Figure 1 and Figure 2 As shown, where Figure 1 This is a cross-sectional view of the air fryer according to an embodiment of this application. Figure 2 This is a three-dimensional structural diagram of an air fryer with a micro switch assembly 7, as shown in an embodiment of this application. The air fryer includes a shell 1 and a pot body 2. The shell 1 has a cooking cavity 11 and a mounting cavity 12 located above the cooking cavity 11. The cooking cavity 11 is used to accommodate the pot body 2, and an opening is formed on the side of the cooking cavity 11 for the pot body 2 to enter and exit. A handle is provided on one side of the pot body 2 so that the user can pull the pot body 2 out of the cooking cavity 11.

[0039] A motor 3 is installed inside the mounting cavity 12, located above the center of the pot body 2. The motor 3 drives a synchronously rotating cooling fan 4 and a centrifugal fan 5. A heating element is located below the centrifugal fan 5. The centrifugal fan 5 delivers hot air heated by the heating element into the pot body 2 to bake the food inside. The cooling fan 4 dissipates heat from the mounting cavity 12, thereby cooling the motor 3 and other electrical components. Specifically, an air outlet communicating with the mounting cavity 12 can be provided on the housing 1, allowing heat from the mounting cavity 12 to be expelled through the air outlet.

[0040] A metal reflector 6 is provided between the cooling fan 4 and the centrifugal fan 5. The reflector 6 divides the housing 1 into a cooking chamber 11 located below and a mounting chamber 12 located above. The reflector 6 can separate the cooling fan 4 and the centrifugal fan 5. The centrifugal fan 5 and the heating element are located in the cooking chamber 11, and the motor 3 and the cooling fan 4 are located in the mounting chamber 12.

[0041] Preferably, Figure 3 Examples of this application Figure 1 An enlarged diagram of point A, as shown below. Figure 3As shown, the reflector 6 includes a top wall 61, a side wall 62 extending downward and outward from the edge of the top wall 61, and a flange 63 extending outward from the edge of the side wall 62. A motor bracket 10 is mounted on the top wall 61 of the reflector 6, and a motor 3 is mounted on the motor bracket 10. The shaft of the motor 3 passes through the motor bracket 10 and the top wall 61 of the reflector 6 from top to bottom and extends into the cooking chamber 11, where it is connected to a centrifugal fan 5 located in the cooking chamber 11. Since the motor bracket 10 is located on the top wall 61, the side wall 62 of the reflector 6 is exposed in the mounting cavity 12, and the flange 63 extends to the opening of the cooking chamber 11.

[0042] A microswitch assembly 7 is provided above the reflector 6 and near the opening of the cooking cavity 11. This microswitch assembly 7 is used to identify whether the pot body 2 is in place, so as to prevent the air fryer from continuing to heat if the pot body 2 is moved out. Optionally, a plastic fastener 8 is installed on the upper surface of the flange 63 near the opening of the cooking cavity 11. The fastener 8 is fixedly installed on the housing 1. The microswitch assembly 7 includes a microswitch 71 and a fixing base 72. The microswitch 71 is fixed to the fastener 8 by the fixing base 72.

[0043] In this embodiment, Figure 4 Examples of this application Figure 2 Enlarged diagram of point B, Figure 5 This is a schematic diagram of the structure of the fastener 8 according to an embodiment of this application. Figure 4 As shown, the micro switch assembly 7 is located on one side of the reflector 6, close to the side wall 62 of the reflector 6. Since the side wall 62 of the reflector 6 is exposed inside the mounting cavity 12, to prevent the side wall 62 of the reflector 6 from transferring heat to the micro switch assembly 7 and causing the micro switch assembly 7 to overheat, the following can be referred to... Figure 4 and Figure 5 In this embodiment, a first heat insulation plate 81 extending upward is provided on the fixing member 8. The first heat insulation plate 81 is located between the side wall 62 of the reflector 6 and the micro switch assembly 7, thereby isolating the side wall 62 of the reflector 6 from the micro switch assembly 7. That is, through the first heat insulation plate 81, the heat of the reflector 6 can be effectively blocked from being transferred from its side wall 62 to the micro switch assembly 7, thereby reducing the temperature rise of the micro switch assembly 7 and extending its service life. Moreover, this structure is particularly suitable for air fryers with a smaller overall motor bracket 10, effectively solving the technical problem that the micro switch 71 is easily damaged by excessive heat in existing air fryers with a smaller overall motor bracket 10.

[0044] In this embodiment, it can be referred to Figure 5The first heat insulation plate 81 is located on the side of the fixing member 8 near the side wall 62 of the reflector 6, that is, the first heat insulation plate 81 is formed by extending upward from the side wall of the fixing member 8 near the reflector 6. In addition, the vertical height of the first heat insulation plate 81 can be 30mm-35mm, preferably 32mm, and the thickness of the first heat insulation plate 81 can be 2mm-3mm, preferably 2.5mm.

[0045] For example, such as Figure 5 As shown, in this embodiment, the first heat insulation plate 81 facing the micro switch assembly 7 is provided with a limiting rib 811. By providing the limiting rib 811, a certain distance can be maintained between the micro switch assembly 7 and the first heat insulation plate 81, ensuring that the micro switch assembly 7 and the first heat insulation plate 81 will not come into contact. For example, if there is a deviation in the installation of the micro switch assembly 7, it may come into contact with the first heat insulation plate 81, affecting the use of the micro switch assembly 7. At this time, the limiting rib 811 can prevent the two from coming into contact, thus ensuring that the micro switch assembly 7 is not affected by the first heat insulation plate 81. Preferably, multiple limiting ribs 811 can be provided, and each limiting rib 811 extends longitudinally and is provided on the side wall of the first heat insulation plate 81.

[0046] Please continue to refer to Figure 5 The aforementioned fastener 8 has a first fixing part 82 located at one end. This first fixing part 82 is fixedly connected to the flange 63 of the reflector 6 by a fastener 9. A first heat insulation plate 81 is placed between the first fixing part 82 and the side wall of the reflector 6 to prevent the side wall of the reflector 6 from transferring heat to the first fixing part 82, which could cause the first fixing part 82 to carbonize and fail due to heat, thus affecting the connection stability of the fastener 9 to the fastener 8 and the reflector 6. Optionally, the first fixing part 82 can be a positioning post on the fastener 8, and the fastener 9 can be a screw. After the screw passes through the reflector 6 and the positioning post, it is threaded into a screw hole on the housing 1 to fix the reflector 6 to the fastener 8.

[0047] Considering the heat transfer between the reflector 6 and the screw, if the screw is exposed to the heat from the reflector 6 for an extended period, causing its temperature to rise, the first fixing part 82 made of plastic in contact with the screw will carbonize and fail under prolonged high temperatures, leading to screw detachment. To solve this problem, preferably... Figure 6 This is a cross-sectional view of the air fryer according to another embodiment of this application. Figure 7 Examples of this application Figure 6 An enlarged diagram of point C. (See diagram below.) Figure 6 and Figure 7As shown, in this embodiment, the flange 63 of the reflector 6 has a tapered hole 634 whose diameter gradually decreases from bottom to top. The screw passes through the tapered hole 634 and the first fixing part 82 of the fixing member 8 from bottom to top to fix the reflector 6 to the fixing member 8. By setting the tapered hole 634, the contact area between the screw nut and the tapered hole 634 is smaller, and thus less heat is transferred from the reflector 6 to the screw. This prevents the screw itself from getting too hot, thus not affecting the first fixing part 82 in contact with it. Consequently, the first fixing part 82 will not experience carbonization failure, and the screw will not fall off.

[0048] Preferably, the screw in this embodiment includes a nut at one end, the slope of which is greater than the slope of the wall of the tapered hole 634. This structure ensures line contact between the nut and the tapered hole 634, effectively reducing the heat transferred from the reflector 6 to the screw, lowering the screw's temperature, and preventing excessive screw temperature from causing carbonization of the first fixing part 82 connected to it. It is understood that the maximum diameter of the tapered hole 634 is greater than the diameter of the screw's nut, thus making the slope of the nut's sidewall greater than the slope of the tapered hole 634's wall.

[0049] In this embodiment, the fixing member 8 is further provided with an upwardly extending second heat insulation plate 83. The second heat insulation plate 83 is located at the end of the fixing member 8 away from the first heat insulation plate 81, and the fixing member 8 has a second fixing part 84 at this end. The second fixing part 84 is fixedly connected to the flange 63 of the reflector 6 by the first fastener. That is, the fixing member 8 and the flange 63 of the reflector 6 can be fixedly connected by the first fixing part 82 and the second fixing part 84. In addition, the second heat insulation plate 83 in this embodiment blocks the connection between the second fixing part 84 and the side wall of the reflector 6, thereby preventing the side wall 62 of the reflector 6 from transferring heat to the second fixing part 84, which would cause the second fixing part 84 to carbonize and fail due to heat, affecting the connection stability of the first fastener to the fixing member 8 and the reflector 6. It should be noted that the first fastener connecting the second fixing part 84 and the reflector 6 is a screw. The reflector 6 has a first tapered hole with a gradually decreasing diameter from bottom to top on the flange 63 corresponding to the second fixing part 84. The screw passes through the first tapered hole and the second fixing part 84 of the fixing member 8 from bottom to top to fix the reflector 6 to the fixing member 8. Optionally, the connection and assembly relationship between the first tapered hole and the screw is the same as the connection and assembly relationship between the screw at the first fixing part 82 and the tapered hole 634 of the reflector 6, so it will not be described again.

[0050] The structure and shape of the second heat insulation plate 83 are the same as those of the first heat insulation plate 81, and the vertical height H of the second heat insulation plate 83 can be 30mm-35mm, preferably 32mm, and the thickness T of the second heat insulation plate 83 can be 2mm-3mm, preferably 2.5mm.

[0051] Furthermore, such as Figure 3 As shown, the flange 63 of the reflector 6 has a step near the opening, and the pot body 2 abuts against the step. In other words, this embodiment uses the flange 63 to form a step. When the pot body 2 is inserted into the cooking cavity 11, it abuts against the step; specifically, the top of the pot body 2 near the handle abuts against the step. This contact prevents hot air from escaping between the pot body 2 and the reflector 6, reducing heat loss and improving the pot body 2's thermal efficiency in baking food. Furthermore, it prevents the handle of the pot body 2 from overheating due to hot air, thus avoiding a decline in user experience.

[0052] For example, the aforementioned step includes a first plate 631 extending horizontally inward from the opening and a second plate 632 extending downward at the inner end of the first plate 631, with the pot body 2 abutting against the second plate 632. In other words, this embodiment, on the one hand, effectively prevents hot air from escaping from the pot body 2 by having the pot body 2 abut against the second plate 632; on the other hand, the bent structure formed between the first plate 631 and the second plate 632, when the pot body 2 abuts against the second plate 632, creates a curved gap between the pot body 2 and the first plate 631 and the second plate 632. This curved gap can block the escape of hot air, achieving a good sealing effect, preventing heat loss, and simultaneously preventing hot air from damaging the heat-sensitive shell 1, thus avoiding melting of the shell 1.

[0053] Preferably, the vertical height of the second plate 632 is greater than or equal to 1 mm. The higher the vertical height of the second plate 632, the lower the probability that hot air will escape to the outside through the gap between the pot body 2 and the second plate 632.

[0054] More preferably, in this embodiment, the flange 63 further forms a third plate 633, which is connected to the end of the second plate 632 that is not connected to the first plate 631. This makes the flange 63 of the reflector 6 have a roughly Z-shaped structure, thereby preventing hot air from escaping from the gap when the pot body 2 is pushed into the cavity and a gap is left, thus avoiding a decrease in the temperature inside the pot body 2 or the formation of drastic temperature fluctuations that would affect the heating efficiency of the pot body 2 on the food. Preferably, the length of the third plate 633 is between 1mm and 10mm, more preferably 5mm to 8mm.

[0055] In this embodiment, preferably, the micro switch assembly 7 is disposed at the corner of the side wall 62 near the reflector 6. The shell 1 and the reflector 6 in this embodiment have generally rectangular edge contours. The micro switch assembly 7 is disposed at the corner of the side wall 62 near the reflector 6, specifically between the corner of the side wall 62 of the reflector 6 and the corner of the shell 1. This placement of the micro switch assembly 7 utilizes the space between the corner of the reflector 6 and the corner of the shell 1 for installation. Furthermore, the space at the corner is larger than at non-corner locations, resulting in less heat transfer and further reducing the impact of heat from inside the air fryer on the micro switch assembly 7.
