[0059] It can be understood that if the circuit board 120 does not surround the motor 130, the cross-sectional area (arrangement area in the top view direction) after the arrangement of the circuit board 120 and the motor 130 will be larger, in addition, if the circuit board 120 and the motor 130 are not arranged along the radial direction of the motor shaft 131, that is, the motor 130 and the circuit board 120 are arranged along the longitudinal direction, the height of the air fryer 100 will be larger.
[0060] The motor 130 comprises a motor shaft 131, and the motor shaft 131 is connected with the impeller 140.
[0061] Optionally, the cross-sectional shape of the circuit board 120 is L-shaped or U-shaped.
[0062] Optionally, the motor 130 includes a first side, a second side, and a third side, with the first side adjacent to the second side and the third side opposite to the first side. At least a portion of the circuit board 120 surrounds the motor 130, i.e., a portion of the circuit board 120 is located between the first side and the outer wall of the body 110, and another portion of the circuit board 120 is located between the second side and the outer wall of the body 110, i.e., L-shaped. Alternatively, the first portion of the circuit board 120 is located between the first side and the outer wall of the body 110, the second portion of the circuit board 120 is located between the second side and the outer wall of the body 110, and the third portion of the circuit board 120 is located between the third side and the outer wall of the body 110, i.e., U-shaped.
[0063] like Figure 1 As shown, in some embodiments, optionally, the circuit board 120 includes a first end 121 and a second end 122 facing away from each other, the first end 121 being closer to the motor 130 than the second end 122; wherein at least a portion of the first end 121 surrounds the motor 130, and the second end 122 extends toward the outer wall of the body 110.
[0064] In this embodiment, the circuit board 120 is defined to include a first end 121 and a second end 122. Specifically, the first end 121 and the second end 122 are opposite to each other, with the first end 121 close to the motor 130 and at least partially surrounding the motor 130, and the second end 122 extending toward the outer wall of the body 110. That is, the inner ring of the circuit board 120 surrounds the motor 130, and the outer ring extends outward, thereby significantly reducing the arrangement area of the motor 130 and the circuit board 120 in the top view and the dimensions in the height direction, thereby reducing the overall volume and size of the air fryer 100.
[0065] like Figure 1 and Figure 2 As shown, in some embodiments, the air fryer 100 may optionally include at least one fan 170, which is disposed on the body 110. The at least one fan 170 and a portion of the circuit board 120 are respectively located on opposite sides of the motor 130 for heat dissipation of the motor 130 and the circuit board 120.
[0066] In this embodiment, the air fryer 100 is further defined as including at least one fan 170. Specifically, at least one motor 130 and a portion of the circuit board 120 are located on opposite sides of the motor 130. It is understood that when the at least one fan 170 is working, the airflow generated can flow to the motor 130 and the circuit board 120, thereby removing the heat from the surface of the motor 130 and the circuit board 120, achieving heat dissipation of the motor 130 and the circuit board 120, which is beneficial to improving the reliability of the air fryer 100.
[0067] In addition, since the partial circuit board 120 and the at least one fan 170 are respectively located on opposite sides of the motor 130, that is, the partial circuit board 120 and the motor 130 are located on the same heat dissipation flow channel, when the at least one fan 170 works, the airflow generated by the at least one fan 170 can flow through the motor 130 and the circuit board 120 in sequence, so that the heat dissipation of the motor 130 and the circuit board 120 can be realized, and the occupied area of the multiple electric control components in the air fryer 100 can be further reduced, and the overall size can be reduced.
[0068] As shown in Figure 1 In some embodiments, optionally, the air fryer 100 further comprises a heat sink 160, and the heat sink 160 is arranged on the circuit board 120 and located between the circuit board 120 and the at least one fan 170.
[0069] In this embodiment, it is defined that the air fryer 100 further comprises a heat sink 160, and specifically, the heat sink 160 is arranged on the circuit board 120, and the heat sink 160 is located between the circuit board 120 and the at least one fan 170, so as to facilitate improving the heat dissipation effect of the circuit board 120, preventing the surface temperature of the circuit board 120 from being too high, thereby reducing the probability of failure of the circuit board 120, and prolonging the service life of the air fryer 100.
[0070] Optionally, the heat sink 160 is opposite to the motor 130, that is, the heat sink 160 surrounds the motor 130 together with the circuit board 120, that is, the positions of the components are reasonably arranged, the space on the left and right sides of the motor 130 is fully utilized, and the arrangement area of the air fryer 100 in the top view direction is significantly reduced, and the overall size is reduced.
[0071] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 In some embodiments, optionally, the at least one fan 170 comprises a first fan 171, and the first fan 171 comprises a first air outlet 172 and a second air outlet 173, the first air outlet 172 is towards the circuit board 120, and the second air outlet 173 is towards the motor 130.
[0072] In this embodiment, it is defined that the at least one fan 170 comprises a first fan 171, and specifically, the first fan 171 comprises a first air outlet 172 and a second air outlet 173, wherein the first air outlet 172 is towards the circuit board 120, and the second air outlet 173 is towards the motor 130. Optionally, the heat sink 160 is located between the first air outlet 172 and the circuit board 120.
[0073] Specifically, when the first fan 171 is in operation, the airflow generated thereby can flow to the motor 130 through the second air outlet 173 in addition to flowing to the circuit board 120 through the first air outlet 172, so that the motor 130 and the circuit board 120 can be cooled, the probability of failure of the motor 130 and the circuit board 120 is reduced, the maintenance cost of the air fryer 100 is reduced, and the service life of the air fryer 100 is prolonged.
[0074] Optionally, the part of the circuit board 120 and the second air outlet 173 are located on opposite sides of the motor 130, that is, the airflow flowing out of the second air outlet 173 can flow through the motor 130 and the circuit board 120 in sequence, which is conducive to improving the heat dissipation effect of the circuit board 120 and meeting the heat dissipation demand.
[0075] As shown in FIGS. Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, the body 110 further comprises a heat dissipation outlet 113, which is located on the side of the circuit board 120 away from the motor 130 and is in communication with the at least one fan 170.

Since the heat dissipation outlet 113 is in communication with the at least one fan 170, that is, the airflow generated by the at least one fan 170 flows through the motor 130 and the circuit board 120, and then flows out of the heat dissipation outlet 113 after taking away the heat on the surface of the motor 130 and the circuit board 120, which is conducive to improving the heat dissipation effect.
[0077] In addition, since the circuit board 120 is located between the heat dissipation outlet 113 and the motor 130, that is, the airflow generated by the fan 170 flows through the circuit board 120 before flowing out of the heat dissipation outlet 113 after flowing through the motor 130, which further improves the heat dissipation effect of the circuit board 120 and meets the heat dissipation demand of the circuit board 120.
[0078] Optionally, the circuit board 120 is configured to be close to the heat dissipation outlet 113. It can be understood that when the airflow generated by the fan 170 can form a plurality of heat dissipation flow channels, the airflow of the plurality of heat dissipation flow channels will eventually flow out of the body 110 through the heat dissipation outlet 113. Since the circuit board 120 is arranged close to the heat dissipation outlet 113, that is, the airflow of the plurality of heat dissipation flow channels will flow through the circuit board 120 before flowing out of the body 110 through the heat dissipation outlet 113, which further improves the heat dissipation effect of the circuit board 120.
[0079] As Figure 5 , Figure 6 and Figure 7 illustrated, in some embodiments, the body 110 is further provided with a heat dissipation inlet 112, and the at least one fan 170 is in communication with the heat dissipation inlet 112.
[0080] In this embodiment, it is defined that the body 110 is further provided with a heat dissipation inlet 112, and specifically, the at least one fan 170 is in communication with the heat dissipation inlet 112, that is, when the at least one fan 170 is working, the airflow can enter the at least one fan 170 from the heat dissipation inlet 112 and flow to the motor 130 and the circuit board 120 respectively, so as to take away the heat on the surface of the motor 130 and the circuit board 120, realize the heat dissipation of the motor 130 and the circuit board 120, and be beneficial to improve the reliability of the air fryer 100.
[0081] As Figure 2 , Figure 3 , Figure 4 and Figure 5 illustrated, in some embodiments, the hot air assembly 240 further includes an electromagnetic member 150, the electromagnetic member 150 is arranged in the body 110 and is electrically connected with the circuit board 120, the electromagnetic member 150 is opposite to the fan blade 140; wherein at least a part of the fan blade 140 has magnetic conductivity, or the hot air assembly 240 further includes a magnetic conductive plate 180, the magnetic conductive plate 180 is located between the electromagnetic member 150 and the fan blade 140.

It can be understood that the electromagnetic member 150 can generate an alternating magnetic field under the condition of being powered on, and under the action of the alternating magnetic field, the fan blade 140 opposite to the electromagnetic member 150 and having magnetic conductivity can heat, or the magnetic conductive plate 180 located between the electromagnetic member 150 and the fan blade 140 heats, at the same time, under the driving of the motor 130, the fan blade 140 rotates in the cooking cavity 111 and takes away the heat to form a hot airflow, and the heat generated by the fan blade 140 or the heat generated by the magnetic conductive plate 180 is dissipated, so as to heat and cook the food materials in the cooking cavity 111.
[0083] Through the interaction between the electromagnetic member 150 and the fan blade 140 having magnetic conductivity, or the interaction between the electromagnetic member 150 and the magnetic conductive plate 180, the fan blade 140 or the magnetic conductive plate 180 can rapidly increase the temperature in a short time, and at the same time, under the rotation of the fan blade 140, the hot airflow is rapidly generated in the cooking cavity 111.
[0084] Optionally, as Figure 9 and Figure 10As shown, the body 110 is further provided with a heat dissipation cavity 114 and a partition plate 230, the heat dissipation cavity 114 is in communication with the heat dissipation inlet 112 and the heat dissipation outlet 113 respectively, the electromagnetic component 150 is located in the heat dissipation cavity 114, and the partition plate 230 is located in the second air outlet part 173 to divide the second air outlet part 173 into two air guide parts arranged along the height direction of the body 110, the air guide part located at the upper part is towards the motor 130, and the air guide part located at the lower part is towards the electromagnetic component 150.
[0085] As shown in Figure 1 , Figure 3 and Figure 6 , optionally, the at least one fan 170 further includes a second fan 175, the second fan 175 is arranged in the body 110, and the second fan 175 is in communication with the heat dissipation inlet 112 and the heat dissipation cavity 114. That is to say, the air or airflow enters the second fan 175 from the heat dissipation inlet 112 and flows into the heat dissipation cavity 114 through the air outlet part of the second fan 175 to sufficiently heat the electromagnetic component 150.
[0086] It can be understood that, during the working process of the air fryer 100, the heat generated by the electromagnetic component 150 is higher than the heat generated by other electric control components such as the motor 130. That is to say, for the heat dissipation cavity 114, on the basis of the air supply of the first fan 171, the second fan 175 is additionally arranged to communicate with the heat dissipation cavity 114, so that the heat dissipation effect of the electromagnetic component 150 can be significantly improved, the heat dissipation demand of the electromagnetic component 150 can be met, the performance of the electromagnetic component 150 can be ensured, the service life of the air fryer 100 can be further prolonged, and the reliability of the air fryer 100 can be improved.
[0087] In some embodiments, along the radial direction of the motor shaft 131, the electromagnetic component 150 and / or the magnetic conducting plate 180 are arranged around the motor 130.
[0088] In this embodiment, specifically, along the radial direction of the motor shaft 131, the electromagnetic component 150 is arranged around the motor 130. Alternatively, along the radial direction of the motor shaft 131, the magnetic conducting plate 180 is arranged around the motor 130. Alternatively, the electromagnetic component 150 and the magnetic conducting plate 180 are both arranged around the motor 130, so that the rational layout of the positions of multiple electric control components in the air fryer 100 can be achieved, which is beneficial to further reducing the arrangement area of the multiple electric control components in the top view direction, reducing the volume of the whole air fryer 100, reducing the overall size of the air fryer 100, and realizing the miniaturization of the air fryer 100.
[0089] As shown in Figure 2 , in some embodiments, optionally, the motor 130 includes a motor body 132 and a motor shaft 131, wherein at least a part of the circuit board 120 is arranged around the motor body 132 along the radial direction of the motor shaft 131, and the motor shaft 131 is arranged in the motor body 132 and connected with the fan blade 140.
[0090] In this embodiment, the motor 130 is defined to include a motor body 132 and a motor shaft 131, specifically, the motor shaft 131 is arranged on the motor body 132, and the motor shaft 131 is connected with the fan blade 140, that is, under the driving of the motor body 132, the motor shaft 131 can drive the fan blade 140 to rotate.
[0091] In the radial direction of the motor shaft 131, at least a part of the circuit board 120 is arranged around the motor body 132, that is, at least part of the circuit board 120 is arranged on the outer circumferential side of the motor body 132, that is, the space on at least one side of the motor body 132 is utilized, so that the arrangement area and the height direction size of the motor 130 and the circuit board 120 in the top view direction can be significantly reduced, and then the occupied area of the multiple electric control components in the air fryer 100 is reduced, the volume of the air fryer 100 is reduced, the overall size of the air fryer 100 is reduced, and the miniaturization of the air fryer 100 is realized.
[0092] As shown in Figure 5 , Figure 6 and Figure 7 , optionally, the body 110 is further provided with at least one heat dissipation air duct 115, and two ends of each heat dissipation air duct 115 are respectively communicated with the heat dissipation inlet 112 and the inlet 174 of one fan 170. For example, in the case that the first fan 171 is started to work, the external air enters from the heat dissipation inlet 112, flows through the heat dissipation air duct 115, enters the first fan 171 through the inlet 174, and flows to the motor 130 and the circuit board 120 through the first air outlet 172 and the second air outlet 173 respectively, so as to take away the heat on the surface of the motor 130 and the circuit board 120, and finally is discharged through the heat dissipation outlet 113, so as to realize the heat dissipation of the motor 130 and the circuit board 120, and avoid the temperature rise of the motor 130 and the circuit board 120.
[0093] At the same time, since the heat dissipation air duct 115 is arranged between the heat dissipation inlet 112 and the fan 170, the heat dissipation inlet 112 and the fan 170 can be arranged far away, so as to reduce the entry of external moisture or impurities into the fan 170, prolong the service life of the fan 170, and improve the reliability of the air fryer 100.
[0094] As shown in Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the air fryer 100 further comprises a blocking rib 190, a water leakage hole 210 and at least one air duct 220, wherein the blocking rib 190 is arranged on the body 110 and located in the at least one heat dissipation air duct 115, the blocking rib 190 is arranged close to the heat dissipation inlet 112 and extends at least partially along the height direction of the body 110, the water leakage hole 210 is arranged in the at least one heat dissipation air duct 115 and communicates with the heat dissipation air duct 115, the water leakage hole 210 is located on the side of the blocking rib 190 close to the heat dissipation inlet 112, and the at least one air duct 220 is arranged on the body 110, each heat dissipation air duct 115 communicates with one fan 170 through one air duct 220.
[0095] Since the blocking rib 190 is arranged close to the heat dissipation inlet 112 and at least partially extends along the height direction of the body 110, the blocking rib 190 can effectively block the moisture or impurities flowing from the heat dissipation inlet 112 during the heat dissipation of the motor 130, the circuit board 120 and the electromagnetic component 150, so as to prevent the external moisture or impurities from entering the fan 170, ensure the service life of the fan 170 and improve the reliability of the air fryer 100.
[0096] Since the water leakage hole 210 communicates with the heat dissipation air duct 115, the water leakage hole 210 can communicate the heat dissipation air duct 115 and the heat dissipation cavity 114. It can be understood that during the heat dissipation of the motor 130, the circuit board 120 and other electric control components, the external moisture entering the heat dissipation air duct 115 from the heat dissipation inlet 112 can flow out through the water leakage hole 210, so as to reduce the external moisture entering the fan 170.
[0097] The water leakage hole 210 is located on the side of the blocking rib 190 close to the heat dissipation inlet 112, that is, during the heat dissipation of the motor 130, the circuit board 120 and other electric control components, even if part of the moisture entering from the heat dissipation inlet 112 does not flow out through the water leakage hole 210, the moisture can also be blocked by the blocking rib 190, so as to further prevent the external moisture from entering the fan 170.
[0098] Since each heat dissipation air duct 115 communicates with one fan 170 through one air duct 220, that is, in the case that the fan 170 is started to work, the external air enters from the heat dissipation inlet 112, flows through the heat dissipation air duct 115, enters the air duct 220, flows into the fan 170 through the air duct 220, carries away the heat on the surface of the circuit board 120 and the motor 130, and is discharged through the heat dissipation outlet 113. By arranging the air duct 220, the airflow flowing to the motor 130, the circuit board 120 and the electromagnetic component 150 can be guided, so as to improve the heat dissipation efficiency of the motor 130, the circuit board 120 and the electromagnetic component 150.
[0099] As shown in FIG. 1, Figure 2 , Figure 4 andFigure 5 As shown, the body 110 comprises a pot body 116 and an air outlet grille 117, wherein the pot body 116 is provided with the cooking cavity 111 and the circuit board 120, the motor 130 and the electromagnetic element 150 are arranged on the pot body 116, the air outlet grille 117 is arranged on the outer side of the pot body 116, and the heat dissipation outlet 113 is arranged on the air outlet grille 117.
