Referring to fig. 7 and 8 together, fig. 7 is a schematic perspective view of a bottom cover plate in the cooking apparatus shown in fig. 1, fig. 8 is a schematic sectional view of the bottom cover plate shown in fig. 7, and a bottom cover plate 1114 is provided with an air inlet 1115 and a flow guiding rib 1116 surrounding the air inlet 1115. The number of the air inlets 1115 may be plural, and the air inlets are arranged at intervals in the middle region of the bottom wall 1111. The guide ribs 1116 are annularly disposed and extend from the bottom wall cover 1114 toward the top of the housing 111 in the axial direction of the cooking body 110 (the dotted line X in fig. 1 may indicate the axis of the cooking body 110).

As shown in fig. 6, an air outlet 1117 is disposed on the peripheral wall 1112 of the casing 111, and air in the external environment enters the casing 111 through the air inlet 1115, is transmitted to the air outlet 1117 along the gap between the inner peripheral wall 1112 of the casing 111 and the outer peripheral wall of the outer pot 112, and then flows out of the casing 111 through the air outlet 1117 to dissipate heat of the cooking body 110. As shown in fig. 2, the number of the air outlets 1117 is multiple, and the air outlets 1117 are arranged at intervals along the circumferential direction of the housing 111, wherein the total length of the area occupied by the multiple air outlets 1117 along the circumferential direction of the housing 111 is not less than 1/3 of the circumference of the housing 111.

Referring to fig. 1, the outer pot 112 is disposed in a cylindrical shape, and the bottom wall of the outer pot 112 may be provided with an outer pot through hole. The heating assembly 113 is located in the outer pot 112 and is disposed at the bottom of the outer pot 112.

In this embodiment, the motor 1142 drives the second blade 1143 to rotate, so that the air in the external environment enters the housing 111 from the air inlet 1115, the cold air entering the housing 111 flows to the motor 1142 under the guiding effect of the guiding rib 1116, and the heat of the motor 1142 is dissipated, thereby preventing the temperature of the motor 1142 from being too high, which is beneficial to improving the reliability of the cooking apparatus 100, or reducing the heat-resistant grade of the motor 1142 on the premise of ensuring the same reliability, and reducing the product cost.

Referring to fig. 1 and 5, the first blade 1141 and the second blade 1143 are disposed at opposite sides of the motor 1142 along the axial direction of the cooking body 110. The first blade 1141 is located on a side of the heating assembly 113 away from the first inner pan 120 and is disposed corresponding to the first overflowing hole 1133 on the heating assembly 113, and the motor 1142 is connected to the first blade 1141 via the outer pan through hole on the bottom wall of the outer pan 112. In the axial direction of the cooking main body 110, the heat pipe 1132 is at least partially overlapped with the first blade 1141 and is disposed around the first blade 1141, so that the heat pipe 1132 can directly heat the air flow formed by the rotation of the first blade 1141, which is beneficial to improving the cooking efficiency of air convection cooking.

In this embodiment, the first blade 1141 is used for outputting the air in the basket body 131 from the bottom of the basket body 131 through the first flow channel, and inputting the air in the basket body 131 into the basket body 131 from the top of the basket body 131 through the second flow channel after the heating assembly 113 heats the food to be cooked.

Specifically, the first blade 1141 may be a centrifugal blade, and when the cooking apparatus 100 performs air convection cooking, the first blade 1141 rotates to output the air in the fry basket body 131 from the bottom of the fry basket body 131 through the first flow channel, and heats up to form hot air after the heating assembly 113 heats up, the hot air flows to the cover 150 through the second flow channel, and then is input into the fry basket body 131 from the top opening of the fry basket body 131 under the guiding and intercepting action of the cover 150 to heat the food placed in the fry basket body 131.

It should be noted that the top of basket body 131 and the bottom of basket body 131 described in this application are relative terms and do not refer to a specific location of basket body 131, as long as the top of basket body 131 is above the bottom of basket body 131. For example, the top of the fry-basket body 131 is not particularly limited to the top opening of the fry-basket body 131, the peripheral wall 1312 of the fry-basket body 131 may be provided with a flow hole, and the air heated by the heating element 113 may be input into the fry-basket body 131 through the second flow passage from the flow hole in the peripheral wall of the fry-basket body 131.

In some embodiments, the first blade 1141 may also be used to input the air heated by the heating assembly 113 in the outer pot 112 into the basket body 131 through the first flow channel from the bottom of the basket body 131, and output the air through the second flow channel from the top of the basket body 131 after flowing through the food to be cooked, which is not limited in this application and can be selected by those skilled in the art according to actual needs.

As shown in fig. 6, the second blade 1143 may be an axial flow blade, and is located on a side of the motor 1142 facing the bottom wall 1111 of the housing 111. The projection of the second blade 1143 along the axial direction of the cooking body 110 overlaps with the air inlet 1115, that is, a plane perpendicular to the axial direction of the cooking body 110 is taken as a reference plane, the intersection point of the reference plane and the axial line of the cooking body 110 is taken as a circle center, the length of the second blade 1143 is taken as a radius to draw a circle to form a reference circle, and the orthographic projection of the air inlet 1115 on the reference plane is at least partially located in the reference circle, which is favorable for improving the efficiency of sucking the external ambient air from the air inlet 1115.

Further, the second blade 1143 and the air guiding rib 1116 may be coaxially disposed along the axial direction of the cooking body 110, and the second blade 1143 is disposed in the air guiding rib 1116, so as to ensure that the air flowing to the surface of the motor 1142 is air in the external environment sucked from the air inlet 1115, thereby further improving the heat dissipation efficiency of the motor 1142.

Specifically, as shown in fig. 10, fig. 10 is another schematic cross-sectional structure diagram of the cooking apparatus shown in fig. 1, an inner diameter a of the air guide rib 1116 is larger than an outer diameter B of the second blade 1143 (a plane perpendicular to an axial direction of the cooking body 110 is taken as a reference plane, an intersection point of the reference plane and the axial line of the cooking body 110 is taken as a center, a circle is drawn by taking a length of the second blade 1143 as a radius to form a reference circle, and a diameter of the reference circle is an outer diameter of the second blade 1143), and a difference between the two is 0.6mm to 6mm, so as to obtain a higher wind speed and improve a heat dissipation effect, for example, the difference between the two may be 0.6mm, 1mm, 2mm, 3mm, 4mm, 5mm or 6mm.

The distance D between the second blade 1143 and the bottom wall 1111 of the housing 111 is smaller than the height C of the air guide rib 1116 (i.e., the distance between the edge of the air guide rib 1116 away from the bottom wall 1111 of the housing 111 and the bottom wall 1111 of the housing 111), so as to prevent the hot air inside the housing 111 from being conveyed to the motor 1142 again by the second blade 1143, thereby improving the heat dissipation effect.

Referring to fig. 6, in the axial direction of the cooking body 110, the air outlet 1117 is located at a side of the heating element 113 away from the motor 1142, and the air introduced by the second blade 1143 is transmitted to the air outlet 1117 along the gap between the inner circumferential wall of the shell 111 and the outer circumferential wall of the outer pot 112 after flowing through the motor 1142, and is output to the external environment from the air outlet 1117, so as to continuously and effectively dissipate heat to the motor 1142, and effectively reduce the temperature rise of the motor 1142.

As shown in fig. 17, the cooking body 210 is also capable of performing heat conduction cooking based on the inner pot 240 (i.e., cooking based on direct contact heat transfer between the heating assembly 213 and the inner pot 240, such as frying, stir-frying, boiling, stewing, steaming, etc.). The cover 250 can be fastened to the cooking body 210 and locked to the cooking body 210. The sensing member and the triggering member cooperate to perform a function control on the cooking body 210 according to a fastening state and a locking state of the cover 250 on the cooking body 210.

Next, each component included in the cooking apparatus 200 of the present application will be described in detail one by one.

Referring to fig. 18, fig. 18 is a schematic cross-sectional structure view of the cooking apparatus shown in fig. 16, in the present embodiment, the cooking main body 210 may include a housing 211, an outer pot 212 disposed in the housing 211, a heating assembly 213 disposed inside the outer pot 212, an air source assembly 214 for performing air convection cooking in cooperation with the heating assembly 213, an oil receiving pan 216 disposed below the heating assembly 213, and a heat insulating cover 215 disposed between the heating assembly 213 and the outer pot 212.

Wherein fry basket 230 can be placed into outer pot 212 and positioned above heating assembly 213, and cooking body 210 can be air convectively cooked based on fry basket 230, wherein heating assembly 213 and air source assembly 214 cooperate to generate a cooking air flow to convectively heat food placed in fry basket 230. The inner pot 240 can be put into the outer pot 212 and contacted with the heating assembly 213, and the cooking body 210 can perform heat conduction cooking based on the inner pot 240, at which time the air source assembly 214 does not operate. The drip pan 216 is used to collect grease leaking from the fry basket 230 during convection cooking to prevent grease from contaminating the heating assembly 213. The heat shield 215 is disposed between the heating element 213 and the outer pot 212 and surrounds the heating element 213 for reflecting heat radiation generated by the heating element 213 during air convection cooking to reduce the temperature rise at the bottom of the outer pot 212.

The specific structures of the housing 211, the outer pan 212, the heating assembly 213, the wind source assembly 214 and the heat shield 215 may be the same as or similar to the previous embodiment, and are within the scope easily understood by those skilled in the art, and are not described herein again. In this embodiment, the heating assembly 213 includes a tray 2131 and a heating tube 2132, and both the heat shield 215 and the oil receiving tray 216 can be fixed on the tray 2131 of the heating assembly 213, so that the tray 2131, the oil receiving tray 216 and the heat shield 215 of the heating assembly 213 are tightly fitted to each other, thereby improving the oil-proof effect of the heating assembly 213. Next, the oil pan 216 will be described in detail.

It should be noted that the description of "oil receiving pan 216 is disposed below heating assembly 213" means that oil receiving pan 216 is disposed below the support structure in heating assembly 213. As shown in fig. 18, in the present embodiment, a tray body 2131 of the heating assembly 213 serves as a support structure for supporting the basket 230 and forms a first overflowing hole 2133, and the oil receiving pan 216 is disposed below the tray body 2131 and in an area surrounded by the heat generating pipes 2132.

In the present embodiment, the number of the heat generating pipes 2132 may be two, and is respectively referred to as a first heat generating pipe 21321 and a second heat generating pipe 21322. The first heat pipe 21321 is circumferentially disposed around the periphery of the first overflowing hole 2133 and serves to generate heat during heat conduction cooking. The second heat generation pipe 21322 is disposed around the periphery of the first heat generation pipe 21321 and is used to generate heat during air flow cooking. For example, when the cooking apparatus 200 performs heat conduction cooking, only the first heat generating pipe 21321 operates, and when the cooking apparatus 200 performs air convection cooking, only the second heat generating pipe 21322 operates or both the first heat generating pipe 21321 and the second heat generating pipe 21322 operate simultaneously.

In some embodiments, the first and second heat generating pipes 21321 and 21322 may also be arranged side by side in the axial direction of the cooking body, that is, there is no nesting relationship between the first and second heat generating pipes 21321 and 21322. In some embodiments, the diameters of the first heat generating tube 21321 and the second heat generating tube 21322 may be equal or substantially equal. In some embodiments, the diameter of the first heat generating pipe 21321 may be slightly larger than that of the second heat generating pipe 21322, which is not limited in this application and can be selected by those skilled in the art according to actual needs.

In some embodiments, the second heat generating tube 21322 may not be fixed by the tray 2131, but may be provided separately from the tray 2131. In this case, the tray body 2131 and the first heat generation pipe 21321 are integrally formed as one heating module, the second heat generation pipe 21322 is formed as another heating module, and the two heating modules are independent of each other.

In some embodiments, the heating assembly 213 may include only the support structure and the second heat generating tube 21322, without the first heat generating tube 21321. Wherein the support structure may include the tray 2131 described above. At this time, the heating assembly does not have a function of direct contact heat transfer, and the cooking apparatus 200 has only an air convection cooking function, not a heat conduction cooking function.

It should be noted that the support structure may be other than a tray, so long as the support structure is capable of supporting the fry basket 230 and is provided with the first overflow hole 2133. The second heat generating tube 21322 may be directly fixed on the supporting structure, or may be disposed relatively independently from the supporting structure, which is not limited in this application and can be selected by those skilled in the art according to actual needs.

In some embodiments, the air source assembly 214 can also input the air heated by the heating assembly 213 in the outer pot 212 into the basket body 231 through the first flow channel from the bottom of the basket body 231, and output the air through the second flow channel from the top of the basket body 231 after flowing through the food to be cooked.

With continued reference to fig. 22, the third overflowing hole 23223 is kept at a predetermined distance from the bottom wall 2311 of the basket body 231 along the axial direction of the cooking body 210 to form a second collecting area for collecting grease on the periphery of the upper cylinder 2322, and when the level of grease in the second collecting area is higher than that of the third overflowing hole 23223, the grease overflows from the third overflowing hole 23223 and flows downward along the inner walls of the upper cylinder 2322 and the lower cylinder 2321 to enter the first collecting area of the oil receiving pan 216.

In this embodiment, the upper cylinder 2322 may include a first upper cylinder 23221 and a second upper cylinder 23222, the first upper cylinder 23221 is integrally formed with the basket body 231, the second upper cylinder 23222 is inserted into and fitted with the first upper cylinder 23221, an upper end of the second upper cylinder 23222 is higher than an upper end of the first upper cylinder 23221, the main cover 23231 is disposed on the second upper cylinder 23222, and the third flow-passing hole 23223 is disposed on the second upper cylinder 23222. In the embodiment, the upper barrel 2322 is arranged to include the first upper barrel 23221 and the second upper barrel 23222 which are connected in an inserting manner, so that the height of the upper barrel 2322 can be effectively increased, and the processing difficulty of the upper barrel 2322 is reduced.

In this embodiment, the second upper cylinder 23222 may be sleeved on the periphery of the first upper cylinder 23221, and in some embodiments, the second upper cylinder 23222 may also be inserted into the first upper cylinder 23221, which is not limited in this application and can be selected by those skilled in the art according to actual requirements. In some embodiments, the upper barrel 2322 may also be integrally disposed, and is within the scope of being easily understood by those skilled in the art, and will not be described herein.

Referring to fig. 22, the oil separating plate 2323 covers the upper end of the upper cylinder 2322, and the dimension of the oil separating plate 2323 in the radial direction of the cooking body 210 is greater than the dimension of the upper cylinder 2322 in the radial direction. In this embodiment, the oil separation plate 2323 and the upper cylinder 2322 may be detachable so as to clean the upper cylinder 2322. Specifically, the oil deflector 2323 includes a main cover plate 23231 and a cylindrical side plate 23232 provided around the main cover plate 23231. The main cover plate 23231 and the cylindrical side plate 23232 may be integrally formed, but the present application does not limit this, and a person skilled in the art may select the main cover plate and the cylindrical side plate according to actual requirements.

Specifically, the main cover plate 23231 may cover an upper end portion of the second upper barrel 23222. The size of the main cover plate 23231 in the radial direction of the cooking body 210 is greater than the size of the second upper cylinder 23222 in the radial direction, for example, the main cover plate 23231 may be disposed in a disc shape, the second upper cylinder 23222 may be disposed in a cylindrical shape, and the radius of the main cover plate 23231 is greater than the outer diameter of the second upper cylinder 23222. The main cover 23231 serves to block grease and/or debris that may fall from the food to be cooked during the convection cooking process, prevent grease and/or debris that may fall from the food to be cooked from directly falling through the bottom wall aperture 2313, and to some extent, reduce the amount of grease and/or debris that may leak through the bottom wall aperture 2313. Grease that falls onto the main deck 23231 may flow down the cylindrical side plate 23232 into a second collection area on the basket body 231.

The cylindrical side plate 23232 is connected to the main cover plate 23231 and extends toward the bottom wall 2311 of the basket body 231.
