Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and more particularly to an air fryer. Background Art

[0002] At present, in the related art, for an air fryer driven by electromagnetic heating, since there are multiple components at multiple positions such as a power board, a motor, and a coil disc that need to dissipate heat, there are relatively many heat dissipation air ducts. Generally, air ducts need to be provided on the outer shell, making the outer shell structure complex and not conducive to mold release, resulting in an increase in the production cost of the air fryer. Summary of the Utility Model

[0003] An embodiment of the utility model aims to solve at least one of the technical problems existing in the prior art.

[0007] It can be understood that since the electrical control components in the air fryer need to dissipate heat, the outer shell structure is complex and cannot be molded in one piece. It is necessary to divide the outer shell into multiple parts for production, increasing the mold cost, the number of parts, the working hours, etc., resulting in an increase in the manufacturing cost of the air fryer.

[0008] The outer shell covers the outside of the appliance body, and at least one through hole is provided on the outer shell.

[0023] In addition, during the assembly process, since the first limiting post is inserted into the limiting groove, the outer shell can be pre-positioned, effectively avoiding the problem of inaccurate alignment caused by the outer shell moving during assembly, reducing the assembly difficulty between the outer shell and the appliance body, and improving the assembly efficiency.

[0026] In some technical solutions, optionally, the air fryer further includes a second connecting member, and the second connecting member is connected to the first limiting post and the second limiting post.

[0027] In this technical solution, it is defined that the air fryer further includes a second connecting member. Specifically, the second connecting member is connected to the first limiting post and the second limiting post. Optionally, the second limiting post is provided with a first connecting hole, the first connecting hole communicates with the limiting groove, the first limiting post is provided with a second connecting hole, and the second connecting member passes through the first connecting hole and is connected to the second connecting hole.

[0028] By providing the second connecting member to further fix the first limiting post and the second limiting post, on the basis of realizing the cooperative limiting of the first limiting post and the second limiting post, it is beneficial to further improve the connection strength between the housing and the appliance body and enhance the assembly effect of the air fryer.

[0029] Optionally, the second connecting member includes a screw.

[0030] In some technical solutions, optionally, the appliance body is further provided with at least one limiting hole; at least one limiting buckle is further provided on the inner wall of the housing, and along the height direction of the appliance body, each limiting buckle is inserted into a limiting hole.

[0031] In this technical solution, it is defined that the appliance body is further provided with at least one limiting hole. Specifically, at least one limiting buckle is further provided on the inner wall of the housing. Along the height direction of the appliance body, each limiting buckle is inserted into a limiting hole, so as to be able to limit the housing in the horizontal direction, prevent the housing from expanding outward to the appliance body, and further improve the assembly stability of the air fryer.

[0032] Optionally, the number of limiting buckles is multiple, and at least two limiting buckles are located on opposite sides of the appliance body to improve the limiting effect on the housing and further enhance the appearance effect of the air fryer.

[0033] In some technical solutions, optionally, the housing is further provided with a plurality of connecting parts, and at least one connecting part and at least one through hole are located on both sides of the appliance body, and the plurality of connecting parts are respectively connected to the appliance body.

[0034] In this technical solution, it is defined that the housing is further provided with a plurality of connecting parts. Specifically, at least one connecting part and at least one through hole are located on both sides of the appliance body. Specifically, at least one connecting part and at least one through hole are located on adjacent sides of the appliance body. And / or, at least one connecting part and at least one through hole are located on opposite sides of the appliance body.

[0035] The plurality of connecting parts are respectively connected to the appliance body, so as to further improve the connection strength between the housing and the appliance body and enhance the assembly stability and reliability of the air fryer.

[0036] Optionally, the connecting part includes a screw post.

[0037] In some technical solutions, optionally, the appliance body is further provided with a heat dissipation cavity and an electrical control component, at least a part of the electrical control component is located in the heat dissipation cavity, and the housing includes a side housing, a top housing and a wind guide tube. Among them, the side housing is provided with at least one through hole, an air inlet and an air outlet, the air outlet is communicated with the heat dissipation cavity, the top housing is connected to the side housing, the top housing is provided with an air inlet groove, one end of the air inlet groove is communicated with the air inlet, the wind guide tube is arranged on the top housing, and the other end of the air inlet groove is communicated with the heat dissipation cavity through the wind guide tube.

[0038] In this technical solution, it is defined that the housing includes a side housing, a top housing and a wind guide tube. Specifically, at least one through hole, an air inlet and an air outlet are respectively arranged on the side housing, the air inlet groove is arranged on the top housing, and both ends of the air inlet groove are respectively communicated with the air inlet and the wind guide tube.

[0039] It can be understood that during the operation of the air fryer, the electrical control component will generate heat. If heat dissipation is not carried out in time, it is easy to cause damage to the electrical control component, increase the maintenance cost of the air fryer, and reduce the service life of the air fryer.

[0040] Specifically, the external air flow enters through the air inlet, flows through the air inlet groove and the wind guide tube in sequence, and then enters the heat dissipation cavity. After taking away the heat on the surface of the electrical control component, it is discharged through the air outlet to dissipate heat from the electrical control component in the heat dissipation cavity, avoid the electrical control component from having too high a temperature rise, reduce the probability of the electrical control component malfunctioning, extend the service life of the electrical control component, and ensure the stable and reliable operation of the air fryer.

[0041] In addition, since the air flow needs to flow through the air inlet groove and the wind guide tube in sequence after entering through the air inlet before it can enter the heat dissipation cavity, that is, the flow path of the air flow is extended, reducing the entry of external moisture or impurities into the electrical control component in the heat dissipation cavity, preventing damage to the electrical control component, and improving the reliability of the air fryer.

[0042] Moreover, by setting the wind guide tube, it is convenient to guide the air flow flowing into the heat dissipation cavity, which is beneficial to improving the heat dissipation efficiency of the electrical control component and further improving the reliability of the air fryer.

[0043] It can be understood that since the wind guide tube is arranged on the top housing, if the buckle positions are arranged at both sides of the front end of the housing and are ejected obliquely by the mold, the housing cannot be demolded in one piece and needs to be demolded in parts, increasing the manufacturing cost.

[0044] By providing at least one through hole at the front end of the housing, it is convenient for the mold to be ejected by the slider from the outside, so as to facilitate the one-piece demolding of the housing, which is beneficial to significantly reducing the manufacturing cost of the housing, and further reducing the production cost of the air fryer.

[0045] Optionally, the air fryer further includes a blower and a baffle rib. The blower is disposed in the appliance body and communicated with the air guide tube. The baffle rib is disposed on the top housing and located in the air inlet groove. The baffle rib is disposed near the air inlet and extends at least partially along the height direction of the appliance body.

[0046] Since the air flow needs to flow through the air inlet groove and the air guide tube in sequence after entering through the air inlet, and then can flow through the blower and enter the heat dissipation cavity, that is to say, the air inlet is set far from the blower. Thus, while ensuring effective heat dissipation of the electrical control components, it can reduce the entry of external moisture or impurities into the blower, extend the service life of the blower, and improve the reliability of the air fryer.

[0047] Optionally, the blower includes a centrifugal blower or an axial flow blower.

[0048] At least a part of the baffle rib extends along the height direction of the appliance body, so that during the heat dissipation process of the electrical control components, it can effectively block the moisture or impurities flowing in from the air inlet, preventing external moisture or impurities from entering the blower or the electrical control components in the heat dissipation cavity through the air inlet groove, ensuring the service life of the blower and the electrical control components, and improving the reliability of the air fryer.

[0049] Optionally, the number of air inlet grooves is multiple, the number of air inlets corresponds to the air inlet grooves one by one, and a baffle rib is disposed at a position near the air inlet in each air inlet groove.

[0050] Optionally, the air fryer further includes a water leakage hole. The water leakage hole is disposed on the top housing, and the air inlet groove is communicated with the heat dissipation cavity through the water leakage hole. The water leakage hole is located on the side of the baffle rib near the air inlet.

[0051] It can be understood that during the heat dissipation process of the electrical control components, after the external moisture enters through the air inlet, it can flow out through the water leakage hole, thus reducing the entry of external moisture into the blower, ensuring the service life of the blower, and improving the reliability of the air fryer.

[0052] The water leakage hole is located on the side of the baffle rib near the air inlet, that is to say, during the heat dissipation process of the electrical control components, even if some of the moisture entering through the air inlet does not flow out through the water leakage hole, it will be blocked by the baffle rib, thus further preventing external moisture from entering the blower, ensuring the service life of the blower, and improving the reliability of the air fryer.

[0053] Optionally, the number of water leakage holes can be set according to actual needs.

[0054] Optionally, along the height direction of the appliance body, the water leakage hole is staggeredly arranged with at least a part of the electrical control components. It can be understood that since the water leakage hole is communicated with the heat dissipation cavity, that is to say, if water enters through the air inlet, the water enters the heat dissipation cavity through the water leakage hole. If the water drops onto the electrical control components, it is also likely to cause circuit failures such as short circuits, affecting the reliable operation of the air fryer.

[0055] Along the height direction of the appliance body, the water leakage holes are arranged offset from at least a part of the electrical control component, so that while discharging moisture, it can prevent water droplets from falling on the electrical control component, thereby avoiding the problem of electrical control component failure and improving the reliability of the air fryer.

[0056] Optionally, the electrical control component includes an electromagnetic component and a motor, the hot air device includes a fan blade, the fan blade is arranged in the cooking cavity and is connected to the motor, and along the height direction of the appliance body, the fan blade is opposite to the electromagnetic component; wherein, at least a part of the fan blade has magnetic permeability, or the hot air device further includes a magnetic conductive plate, and the magnetic conductive plate is arranged between the fan blade and the electromagnetic component. That is to say, driven by the motor, the fan blade can rotate in the cooking cavity.

[0057] At least a part of the fan blade has magnetic permeability, and along the height direction of the appliance body, the fan blade is opposite to the electromagnetic component, so that at least a part of the fan blade can generate heat when the electromagnetic component is powered on. At the same time, driven by the motor, the fan blade rotates in the cooking cavity to form a hot air flow circulating in the cooking cavity, thereby heating and cooking the food ingredients in the cooking cavity.

[0058] Optionally, when at least a part of the fan blade has magnetic permeability, the hot air device further includes a heat insulation plate, and the heat insulation plate is arranged between the fan blade and the electromagnetic component, so that it can effectively reduce the heat generated by the fan blade from being transferred to the electromagnetic component, avoid the electromagnetic component from having too high a temperature rise due to the heat generated by the fan blade, thereby affecting the performance of the electromagnetic component, extend the service life of the electromagnetic component, and improve the reliability of the air fryer.

[0059] Among them, the heat insulation plate includes but is not limited to microcrystalline plate, glass, etc.

[0060] Or, the hot air device further includes a magnetic conductive plate. It can be understood that the magnetic conductive plate has magnetic permeability, and the magnetic conductive plate is arranged between the fan blade and the electromagnetic component. Since along the height direction of the appliance body, the fan blade is opposite to the electromagnetic component, therefore, the magnetic conductive plate is opposite to the electromagnetic component. That is to say, when the electromagnetic component is powered on, the magnetic conductive plate can generate heat. At the same time, driven by the motor, the fan blade rotates in the cooking cavity to form a hot air flow circulating in the cooking cavity, thereby heating and cooking the food ingredients in the cooking cavity.

[0061] Optionally, when the hot air device includes a magnetic conductive plate, a heat insulation layer is arranged on the side of the magnetic conductive plate facing the electromagnetic component, that is, a layer of heat insulation material is coated on the side of the magnetic conductive plate facing the electromagnetic component, so that it can effectively reduce the heat generated by the magnetic conductive plate from being transferred to the electromagnetic component, avoid the electromagnetic component from having too high a temperature rise due to the heat generated by the magnetic conductive plate, thereby affecting the performance of the electromagnetic component, extend the service life of the electromagnetic component, reduce the probability of the electromagnetic component failing, and reduce the maintenance cost of the air fryer.

Alternatively, the second limiting post 162 is provided on the outer shell 130, that is, the first part is the second limiting post 162, and the first limiting post 161 is provided on the appliance body 110, that is, the second part is the first limiting post 161. Specifically, it can be set according to actual needs.

[0095] The second limiting post 162 is provided with a limiting groove 163. Along the height direction of the appliance body 110, the first limiting post 161 is inserted into the limiting groove 163, so as to be able to limit the outer shell 130 in the horizontal direction, which is beneficial to further improve the connection strength between the outer shell 130 and the appliance body 110 and improve the assembly reliability of the air fryer 100.

[0096] In addition, during the assembly process, since the first limiting post 161 is inserted into the limiting groove 163, the outer shell 130 can be pre-positioned, effectively avoiding the problem of inaccurate alignment caused by the outer shell 130 moving during assembly, reducing the assembly difficulty between the outer shell 130 and the appliance body 110, and improving the assembly efficiency.

[0097] As Figure 4 shown, in some embodiments, optionally, the second limiting post 162 is further provided with a positioning platform 164. The positioning platform 164 is arranged in the limiting groove 163, and the end of the first limiting post 161 inserted into the limiting groove 163 abuts against the positioning platform 164.

[0098] In this embodiment, it is defined that the second limiting post 162 is further provided with a positioning platform 164. Specifically, the positioning platform 164 is arranged in the limiting groove 163. When the first limiting post 161 is inserted into the limiting groove 163, the end of the first limiting post 161 abuts against the positioning platform 164, so as to limit the outer shell 130 in the height direction of the appliance body 110, which is beneficial to further improve the reliability of the assembled air fryer 100.

[0099] As Figure 4 shown, in some embodiments, optionally, the air fryer 100 further includes a second connecting member 170, and the second connecting member 170 is connected to the first limiting post 161 and the second limiting post 162.

[0100] In this embodiment, it is defined that the air fryer 100 further includes a second connecting member 170. Specifically, the second connecting member 170 is connected to the first limiting post 161 and the second limiting post 162. Optionally, the second limiting post 162 is provided with a first connecting hole, the first connecting hole communicates with the limiting groove 163, the first limiting post 161 is provided with a second connecting hole, and the second connecting member 170 passes through the first connecting hole and is connected to the second connecting hole.

[0101] By providing the second connecting member 170 to further fix the first limiting post 161 and the second limiting post 162, on the basis of realizing the cooperative limitation of the first limiting post 161 and the second limiting post 162, it is beneficial to further improve the connection strength between the outer shell 130 and the appliance body 110 and enhance the assembly effect of the air fryer 100.

[0102] Optionally, the second connecting member 170 includes a screw.

[0103] As Figure 1 and Figure 6 shown, in some embodiments, optionally, the appliance body 110 is further provided with at least one limiting hole 112; at least one limiting buckle 180 is further provided on the inner wall of the outer shell 130, and along the height direction of the appliance body 110, each limiting buckle 180 is inserted into a limiting hole 112.

[0104] In this embodiment, it is defined that the appliance body 110 is further provided with at least one limiting hole 112. Specifically, at least one limiting buckle 180 is further provided on the inner wall of the outer shell 130. Along the height direction of the appliance body 110, each limiting buckle 180 is inserted into a limiting hole 112, so as to be able to limit the outer shell 130 in the horizontal direction and prevent the outer shell 130 from expanding outwardly relative to the appliance body 110, further improving the assembly stability of the air fryer 100.

[0105] Optionally, the number of the limiting buckles 180 is multiple, and at least two limiting buckles 180 are located on opposite sides of the appliance body 110 to improve the limiting effect on the outer shell 130 and further enhance the appearance effect of the air fryer 100.

[0106] As Figure 1 shown, in some embodiments, optionally, the outer shell 130 is further provided with a plurality of connecting portions 133, at least one connecting portion 133 and at least one through hole 131 are located on both sides of the appliance body 110, and the plurality of connecting portions 133 are respectively connected to the appliance body 110.

[0107] In this embodiment, it is defined that the housing 130 is further provided with a plurality of connecting portions 133. Specifically, at least one connecting portion 133 and at least one through hole 131 are located on two sides of the appliance body 110. Specifically, at least one connecting portion 133 and at least one through hole 131 are located on adjacent sides of the appliance body 110. And / or, at least one connecting portion 133 and at least one through hole 131 are located on opposite sides of the appliance body 110.

[0108] The plurality of connecting portions 133 are respectively connected to the appliance body 110, so as to further improve the connection strength between the housing 130 and the appliance body 110, and enhance the assembly stability and reliability of the air fryer 100.

[0109] Optionally, the connecting portion 133 includes a screw post.

[0110] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 10 As shown in

[0111] In this embodiment, it is defined that the housing 130 includes a side housing 134, a top housing 135 and a wind guide tube 139. Specifically, at least one through hole 131, an air inlet 136 and an air outlet 137 are respectively arranged on the side housing 134, the air inlet groove 138 is arranged on the top housing 135, and both ends of the air inlet groove 138 are respectively communicated with the air inlet 136 and the wind guide tube 139.

[0112] It can be understood that during the operation of the air fryer 100, the electric control component 114 will generate heat. If heat dissipation is not carried out in time, it is easy to cause damage to the electric control component 114, increase the maintenance cost of the air fryer 100, and reduce the service life of the air fryer 100.

[0113] Specifically, the external air flow enters through the air inlet 136, flows through the air inlet groove 138 and the air guide cylinder 139 in sequence, and then enters the heat dissipation cavity 113. After taking away the heat on the surface of the electrical control component 114, it is discharged through the air outlet 137, so as to dissipate the heat of the electrical control component 114 in the heat dissipation cavity 113, avoid the electrical control component 114 from having too high a temperature rise, reduce the probability of the electrical control component 114 malfunctioning, extend the service life of the electrical control component 114, and ensure the stable and reliable operation of the air fryer 100.

[0114] In addition, since the air flow needs to flow through the air inlet groove 138 and the air guide cylinder 139 in sequence after entering through the air inlet 136 before it can enter the heat dissipation cavity 113, that is, the flow path of the air flow is extended, reducing the entry of external moisture or impurities into the electrical control component 114 in the heat dissipation cavity 113, preventing the electrical control component 114 from being damaged, and improving the reliability of the air fryer 100.

[0115] Moreover, by setting the air guide cylinder 139, it is convenient to guide the air flow flowing into the heat dissipation cavity 113, which is conducive to improving the heat dissipation efficiency of the electrical control component 114 and further improving the reliability of the air fryer 100.

[0116] It can be understood that since the air guide cylinder 139 is provided on the top housing 135, if the buckle positions are provided at both sides of the front end of the outer shell 130 by inclined ejection molding, the outer shell 130 cannot be ejected in one piece and needs to be separated into parts, increasing the manufacturing cost.

[0117] By providing at least one through hole 131 at the front end of the outer shell 130, it is convenient for the mold to be ejected from the outside by a slide block, so as to facilitate the one-piece ejection of the outer shell 130, which is conducive to significantly reducing the manufacturing cost of the outer shell 130 and further reducing the production cost of the air fryer 100.

[0118] Such as Figure 2 and Figure 10 As shown, optionally, the air fryer 100 further includes a blower 190 and a retaining rib 210. Among them, the blower 190 is provided on the appliance body 110 and is communicated with the air guide cylinder 139. The retaining rib 210 is provided on the top housing 135 and is located in the air inlet groove 138. The retaining rib 210 is arranged close to the air inlet 136 and extends at least partially in the height direction of the appliance body 110.

[0119] Since the air flow needs to flow through the air inlet groove 138 and the air guide cylinder 139 in sequence after entering through the air inlet 136 before it can flow through the blower 190 and enter the heat dissipation cavity 113, that is to say, the air inlet 136 is arranged far from the blower 190. Thus, while ensuring effective heat dissipation of the electrical control component 114, it can reduce the entry of external moisture or impurities into the blower 190, extend the service life of the blower 190, and improve the reliability of the air fryer 100.

[0120] Optionally, the fan 190 includes a centrifugal fan 190 or an axial flow fan 190 .

[0121] At least a portion of the retaining rib 210 extends in the height direction of the appliance body 110, so that in the process of heat dissipation of the electrical control component 114, it can effectively block moisture or impurities flowing in from the air inlet 136, preventing external moisture or impurities from entering the fan 190 or the electrical control component 114 in the heat dissipation cavity 113 through the air inlet groove 138, thereby ensuring the service life of the fan 190 and the electrical control component 114 and improving the reliability of the air fryer 100.

[0122] Optionally, there are multiple air inlet slots 138 , and the number of air inlet ports 136 corresponds one-to-one to the air inlet slots 138 . A retaining rib 210 is provided near the air inlet port 136 in each air inlet slot 138 .

[0123] like Figure 2 As shown, optionally, the air fryer 100 also includes a water leakage hole 220, which is arranged on the top shell 135, and the air inlet groove 138 is connected with the heat dissipation cavity 113 through the water leakage hole 220. The water leakage hole 220 is located on the side of the retaining rib 210 close to the air inlet 136.

[0124] It is understandable that in the process of dissipating heat for the electrical control unit 114 , external moisture can enter from the air inlet 136 and flow out through the water leakage hole 220 , thereby reducing the external moisture entering the fan 190 , ensuring the service life of the fan 190 , and improving the reliability of the air fryer 100 .

[0125] The water leakage hole 220 is located on the side of the retaining rib 210 close to the air inlet 136. That is to say, in the process of dissipating heat for the electrical control component 114, even if part of the moisture entering from the air inlet 136 does not flow out through the water leakage hole 220, it will be blocked by the retaining rib 210, thereby further preventing external moisture from entering the fan 190, ensuring the service life of the fan 190, and improving the reliability of the air fryer 100.

[0126] Optionally, the number of the water leakage holes 220 can be set according to actual needs.

[0127] Optionally, the water leakage hole 220 is staggered with at least a portion of the electric control unit 114 along the height direction of the appliance body 110. It is understandable that since the water leakage hole 220 is connected to the heat dissipation cavity 113, that is, if water enters from the air inlet 136, the water enters the heat dissipation cavity 113 from the water leakage hole 220, and if the water drops onto the electric control unit 114, it is also easy to cause circuit faults such as short circuits, affecting the reliable operation of the air fryer 100.

[0128] In the height direction of the appliance body 110, the water leakage hole 220 is arranged offset from at least a part of the electrical control component 114, so that while discharging moisture, it can prevent water droplets from falling on the electrical control component 114, thereby avoiding the problem of the electrical control component 114 malfunctioning and improving the reliability of the air fryer 100.

[0129] As Figure 3 and Figure 10 shown, optionally, the electrical control component 114 includes an electromagnetic component 230 and a motor 240, the hot air device 120 includes a wind blade 121, the wind blade 121 is arranged in the cooking cavity 111 and is connected to the motor 240. In the height direction of the appliance body 110, the wind blade 121 is opposite to the electromagnetic component 230; wherein, at least a part of the wind blade 121 has magnetic permeability, or the hot air device 120 further includes a magnetic conductive plate 122, and the magnetic conductive plate 122 is arranged between the wind blade 121 and the electromagnetic component 230. That is to say, driven by the motor 240, the wind blade 121 can rotate in the cooking cavity 111.

[0130] At least a part of the wind blade 121 has magnetic permeability, and in the height direction of the appliance body 110, the wind blade 121 is opposite to the electromagnetic component 230, so that when the electromagnetic component 230 is energized, at least a part of the wind blade 121 can generate heat. At the same time, driven by the motor 240, the wind blade 121 rotates in the cooking cavity 111 to form a hot air flow circulating in the cooking cavity 111, thereby heating and cooking the food in the cooking cavity 111.

[0131] Optionally, when at least a part of the wind blade 121 has magnetic permeability, the hot air device 120 further includes a heat insulation plate, and the heat insulation plate is arranged between the wind blade 121 and the electromagnetic component 230, so that it can effectively reduce the heat generated by the wind blade 121 from being transferred to the electromagnetic component 230, avoid the electromagnetic component 230 having too high a temperature rise due to the heat generated by the wind blade 121, thereby affecting the performance of the electromagnetic component 230, extend the service life of the electromagnetic component 230, and improve the reliability of the air fryer 100.

[0132] Among them, the heat insulation plate includes but is not limited to microcrystalline plates, glass, etc.

[0133] Or, the hot air device 120 further includes a magnetic conductive plate 122. It can be understood that the magnetic conductive plate 122 has magnetic permeability, and the magnetic conductive plate 122 is arranged between the wind blade 121 and the electromagnetic component 230. Since in the height direction of the appliance body 110, the wind blade 121 is opposite to the electromagnetic component 230, therefore, the magnetic conductive plate 122 is opposite to the electromagnetic component 230. That is to say, when the electromagnetic component 230 is energized, the magnetic conductive plate 122 can generate heat. At the same time, driven by the motor 240, the wind blade 121 rotates in the cooking cavity 111 to form a hot air flow circulating in the cooking cavity 111, thereby heating and cooking the food in the cooking cavity 111.

[0134] Optionally, when the hot air device 120 includes a magnetic conductive plate 122, a heat insulation layer is provided on the side of the magnetic conductive plate 122 facing the electromagnetic component 230, that is, a layer of heat insulation material is coated on the side of the magnetic conductive plate 122 facing the electromagnetic component 230, so as to effectively reduce the heat transfer from the magnetic conductive plate 122 to the electromagnetic component 230, avoid the overheating of the electromagnetic component 230 caused by the heat generated by the magnetic conductive plate 122, further affect the performance of the electromagnetic component 230, extend the service life of the electromagnetic component 230, reduce the probability of the electromagnetic component 230 malfunctioning, and reduce the maintenance cost of the air fryer 100.

[0135] In a specific embodiment, as Figure 1 shown, a screw post (the first limiting post 161) and two screw through holes (through holes 131) are provided at the front end of the outer shell 130. Correspondingly, a screw table (limiting groove 163) and a screw post (the second limiting post 162) are provided on the inner cover (appliance body 110) to fix the outer shell 130 and the inner cover (appliance body 110). At the same time, a sticker (decoration 150) is pasted on the front end to cover the screw (the first connecting member 140) and play a decorative role.

[0136] There are complex structures such as an air duct (air inlet groove 138) on the outer shell 130. A screw post (the second limiting post 162) is provided at the front end of the outer shell 130. The screw post is arranged between two air ducts to facilitate the ejection of the mold by the inclined ejector. At the same time, the two sides at the front end of the outer shell 130 are no longer provided with buckles that need to be ejected from the inside by the inclined ejector, but are designed as two through holes 131, and the mold is ejected by the slider from the outside.

[0137] Two buckles (limiting buckles 180) are also designed on both sides of the outer shell 130, which are buckled on the fuselage (appliance body 110). A screw post (connecting part 133) is designed at the bottom of the outer shell 130 to fasten with the bottom cover.

[0138] In addition, a heating air blade 121 is installed on the motor 240. The heat insulation plate separates the electromagnetic coil (electromagnetic component 230) from the air blade 121. The heat insulation plate and the inner cover form a cavity (heat dissipation cavity 113), and the electromagnetic coil is installed therein to form a heat dissipation air duct for the electromagnetic coil. The electromagnetic coil drives the heating blade (air blade 121) to generate heat, and the motor 240 drives the heating blade to rotate, so as to form a hot air flow in the extraction barrel (cooking cavity 111) and start the baking function.

[0139] There are left and right air inlets 136 provided at the rear end of the housing 130, which are respectively connected to the left and right air inlet slots 138. The housing 130 is provided with straight sides (usually a cylinder, i.e., the air guide cylinder 139) directly above the air inlets of the left and right fans 190. The straight sides and the air inlets of the fans 190 form an air duct correspondingly. The left and right air inlet slots 138 are communicated with the straight sides to form a complete air inlet channel. The air inlet slot 138 is provided with a water blocking rib (the blocking rib 210), and a water leakage hole 220 is arranged in the slot to prevent water from flowing to the fan 190 after water enters.
