[0047] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0048] Reference below Figure 1-Figure 13 A cooking appliance 100 according to an embodiment of the present invention is described.
[0049] like Figure 1-Figure 4 As shown, the cooking appliance 100 according to some embodiments of the present invention includes a cooking body 10 , a cover assembly 20 and a heating device 15 .
[0050] The cooking body 10 includes a cooking container 11, and a cover assembly 20 is arranged on the cooking body 10. The cover assembly 20 is used to open and close the cooking container 11, so that a cooking cavity is defined between the cooking container 11 and the cover assembly 20, wherein the cover assembly 20 can be detachably arranged on the cooking body 10, and can also be pivotally arranged on the cooking body 10. A first fan 21 is arranged on the side of the cover assembly 20 facing the cooking body 10, and the first fan 21 is rotatable relative to the cover assembly 20.
[0051] The heating device 15 is used to heat the food in the cooking container 11. The heating device 15 can be arranged on the cooking body 10. For example, the heating device 15 can be arranged below the cooking container 11, so as to directly heat the bottom of the cooking container 11. Of course, the heating device 15 can also be arranged at other positions, for example, the heating device 15 can also be arranged on the cover assembly 20. In addition, the heating device can also include multiple heating devices, which are respectively arranged on the cooking container 11 and the cover assembly 20.
[0052] Furthermore, the cooking appliance 100 further includes an air frying head 30 and a first fan 21. The air frying head 30 is detachably provided on the cover assembly 20. The first fan 21 is provided on the cover assembly 20 or the air frying head 30. The air frying head 30 includes a motor 32. The motor 32 is used to drive the first fan 21 to rotate. The cooking appliance 100 includes a first cooking mode and a second cooking mode. Hot air is generated by the heating of the heating device 15 and the rotation of the first fan 21, thereby forming a first cooking mode of convection heating cooking in the cooking cavity. The second cooking mode is formed by heating the cooking container 11 by the heating device 15.
[0053] According to the cooking utensil 100 of the embodiment of the present invention, by detachably arranging the air-frying head 30 on the cover assembly 20, convection heating cooking can be achieved in a first cooking mode through the cooperation of the cooking body 10, the cover assembly 20 and the air-frying head 30, and the motor 32 is used to drive the first fan 21 to rotate. Alternatively, in a second cooking mode, the motor 32 of the air-frying head 30 is controlled not to work, or the air-frying head 30 is detached, and cooking is achieved through the cooperation of the cooking body 10 and the cover assembly 20. The two cooking modes can be cooked in one piece, and there is no need to switch back and forth between the cover assembly 20 and the air-frying head 30. The operation is simple and the user experience is better.
[0054] According to some embodiments of the present invention, the air frying head 30 is disposed on a side of the cover assembly 20 that faces away from the cooking body 10. Figure 2 As shown, the air blasting head 30 is disposed on the outer top of the cover assembly 20 , that is, the air blasting head 30 and the first fan 21 are separated by the cover assembly 20 , thereby facilitating cleaning of various components.
[0055] The cooking appliance 100 can be in the first cooking mode, through the cooperation of the cooking body 10, the cover assembly 20 and the air frying head 30, the motor 32 can still drive the first fan 21 to rotate to achieve cooking when it is not directly connected to the first fan 21. The cooking appliance 100 can also be in the second cooking mode, control the air frying head 30 not to work, and achieve cooking through the cooperation of the cooking body 10 and the cover assembly 20. The two cooking modes can be cooked in one, and there is no need to switch back and forth between the cover assembly 20 and the air frying head 30, which is simple to operate and provides a better user experience.
[0056] In some embodiments, the motor 32 is provided with a first magnet 322 that rotates synchronously with its rotor, and the first fan 21 is provided with a second magnet 212, and the first magnet 322 is suitable for being attracted to the second magnet 212, so as to drive the first fan 21 to rotate when the motor 32 is working. That is to say, in this embodiment, the magnetic drive principle is utilized, and the motor 32 on the external air frying head 30 is used to detachably drive the first fan 21 to rotate, and the first fan 21 is used to drive the internal heat field circulation to achieve the baking cycle cooking effect.
[0057] In some embodiments, the air frying head 30 has an air inlet 311 and an air outlet 312 , one of the air inlet 311 and the air outlet 312 is located on the top surface of the air frying head 30 , and the other is located on the side surface of the air frying head 30 .
[0058] In some specific embodiments, the air blasting head 30 also includes a shell 31 and a second fan 34, the air inlet 311 and the air outlet 312 are arranged in the shell 31, the second fan 34 is arranged in the shell 31, the motor 32 is connected to the second fan 34, thereby driving the second fan 34 to rotate, and the outside air enters the shell 31 from the air inlet 311 under the action of the second fan 34, and then is discharged from the air outlet 312. In this process, the air discharged from the air outlet 312 takes away the heat around the motor 32, thereby dissipating the heat of the motor 32 and improving the service life of the motor 32.
[0059] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, a mounting shaft 22 is provided on one side of the cover assembly 20 facing the cooking body 10 , and the first fan 21 is rotatably mounted on the mounting shaft 22 .
[0060] In order to reduce the movement of the first fan 21 relative to the installation shaft 22 , a bearing 28 is installed on the installation shaft 22 , so that the first fan 21 is rotatably disposed on the installation shaft 22 via the bearing 28 .
[0061] Specifically, the mounting shaft 22 extends along the thickness direction of the cover assembly 20. Figure 3 As shown, when the cover assembly 20 is in a state of closing the cooking container 11, the installation shaft 22 extends in the up-down direction, and the upper end of the installation shaft 22 is connected to the cover assembly 20, the bearing 28 is sleeved on the installation shaft 22 and one side stops against the shoulder of the installation shaft 22, the lower side of the first fan 21 is provided with a limiting convex ring, and the upper side of the first fan 21 is provided with a clamping piece, and the bearing 28 is matched between the limiting convex ring and the clamping piece, so as to ensure the positioning installation of the first fan 21. By providing the installation shaft 22, not only the positioning installation of the first fan 21 can be ensured, but also the centering effect can be ensured to prevent the first fan 21 from shaking.
[0062] like Figure 4 As shown, in some embodiments, a limiting member 221 is provided on the mounting shaft 22 to axially limit the bearing 28, thereby axially limiting the first fan 21, ensuring the installation reliability of the first fan 21, and ensuring that the first fan 21 can operate normally.
[0063] In some embodiments, the mounting shaft 22 is detachably connected to the cover assembly 20. Specifically, the mounting shaft 22 can be plug-fitted with the cover assembly 20, or can be attracted to the cover assembly 20 through a magnetic attraction structure, or can be detachably connected to the cover assembly 20 through a connector, or can be threadedly connected to the cover assembly 20 through a threaded structure, so that in a cooking mode that does not require the air frying head 30 to work, the first fan 21 can be removed from the cover assembly 20 for easy storage and cleaning.
[0064] According to some embodiments of the present invention, the air blasting head 30 is detachably connected to the cover assembly 20 .
[0065] For example, when the cooking appliance 100 is required to work in the first cooking mode, the cover assembly 20 is covered on the cooking body 10, the air-frying head 30 is set on the top of the cover assembly 20, and the first fan 21 is set under the cover assembly 20. When the cooking appliance 100 is required to work in the second cooking mode, the cover assembly 20 is covered on the cooking body 10, and the air-frying head 30, the first fan 21, the mounting shaft 22, etc. can be removed. Of course, the above structure can also be left intact, which is convenient for assembly and disassembly.
[0066] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the cover assembly 20 includes a metal cover 29, which is arranged between the motor 32 and the first fan 21. The metal cover 29 is provided with cover teeth that snap into place with the cooking container 11, thereby ensuring the connection reliability and sealing between the metal cover 29 and the cooking container 11.
[0067] According to some embodiments of the present invention, one of the air blasting head 30 and the cover assembly 20 has a positioning recess 27 , and the other of the air blasting head 30 and the cover assembly 20 has a positioning protrusion 33 , and the positioning protrusion 33 cooperates with the positioning recess 27 .
[0068] Specifically, Figure 7 As shown, a positioning protrusion 33 protruding downward is provided at the bottom of the air-frying head 30, and a positioning recess 27 recessed downward is provided at the top of the cover assembly 20. The air-frying head 30 is engaged in the positioning recess 27 through the positioning protrusion 33, so that the air-frying head 30 is positioned and installed on the cover assembly 20, preventing the air-frying head 30 from shaking relative to the cover assembly 20 or detaching from the cover assembly 20 when the cooking utensil 100 is working, thereby ensuring that the cooking utensil 100 can work normally.
[0069] Therefore, by adopting a structure in which the positioning protrusion 33 cooperates with the positioning recess 27, the positioning installation of the air blasting head 30 on the cover assembly 20 can be achieved, ensuring the installation stability and reliability of the air blasting head 30 on the cover assembly 20, thereby ensuring that the air blasting head 30 can work normally.
[0070] In some embodiments, the cooking container 11 further includes an air-frying container 12 , and the air-frying container 12 is detachably disposed in the cooking container 11 .
[0071] In some examples, the air-frying container 12 has an air hole 121 . When the air-frying container 12 is placed in the cooking container 11 , an air duct is defined between the air-frying container 12 and the cooking container 11 . The air duct is connected to the inner cavity of the air-frying container 12 through the air hole 121 .
[0072] Thus, by providing the air holes 121, it is convenient to better cook the food in the inner cavity of the air frying container 12. For example, in the air frying cooking mode, when the air frying container 12 is used to fry the food in its inner cavity, the air holes 121 can facilitate the hot air to flow between the air duct and the inner cavity of the air frying container 12, thereby improving the frying and cooking effect of the food in the air frying container 12.
[0073] In some specific examples, the air hole 121 is provided on the bottom wall of the air frying container 12, so that the hot air in the air duct can enter the air frying container 12 from the bottom, and then the hot air in the air frying container 12 flows upward under the action of the first fan 21 and flows into the air duct again, and the cycle repeats.
[0074] According to some embodiments of the present invention, the first cooking mode is a hot air convection heating mode, and the second cooking mode is a conduction heating mode. When the cooking appliance 100 is in the first cooking mode, the cover assembly 20 covers the cooking body 10, and the air-frying head 30 is arranged on the cover assembly 20. The heating of the heating device 15 and the rotation of the first fan 21 generate hot air to perform hot air convection heating on the food in the cooking cavity; when the cooking appliance 100 is in the second cooking mode, the cover assembly 20 covers the cooking body 10, and the air-frying head 30 is allowed to be separated from the cover assembly 20, and the heating device 15 performs conduction heating on the food in the cooking cavity.
[0075] That is, when the cooking device 100 is in the hot air convection heating mode, the cover assembly 20 covers the cooking body 10, and the air-frying head 30 is arranged on the cover assembly 20, the heating device 15 heats the cooking container 11, and the motor 32 drives the first fan 21 to rotate. When the cooking device 100 is in the conduction heating mode, the cover assembly 20 covers the cooking body 10, and the air-frying head 30 is allowed to be separated from the cover assembly 20 and the air-frying container 12 is allowed to be separated from the cooking container 11. Of course, the air-frying head 30 may not be separated from the cover assembly 20. In this cooking mode, the heating device 15 heats the cooking container 11, and the air-frying head 30 is controlled not to work.
[0076] In some examples, the first cooking mode is an air frying cooking mode, and the second cooking mode is a steam cooking mode, such as a pressure cooking mode.
[0077] like Figure 1-Figure 5 as well as Figure 12-13 As shown, a cooking appliance 100 according to some other embodiments of the present invention includes a cooking cavity, a first fan 21 and a heating device 15, wherein the first fan 21 supplies air toward the cooking cavity, and the heating device 15 is used to heat food in the cooking cavity.
[0078] Furthermore, the cooking utensil 100 also includes an air-frying container 12 and an air guide cover 13. The air-frying container 12 is used to contain food. The air-frying container 12 is arranged in the cooking cavity. An air duct is defined between the side wall of the cooking cavity and the air-frying container 12. The lower portion of the air-frying container 12 has an air hole 121, and the air duct is connected to the inner cavity of the air-frying container 12 through the air hole 121.
[0079] The air guide cover 13 is disposed above the air frying container 12. The air guide cover 13 has a vent 131. The air guide cover 13 is used to guide the wind blown out by the first fan 21 to the air duct. For example, the hot air generated by the rotation of the first fan 21 and the heating device 15 can be guided to the air duct and enter the air frying container 12 from the air hole 121, so as to be used for baking food.
[0080] According to the cooking appliance 100 of the embodiment of the present invention, by providing the air guide cover 13 above the air frying container 12, the air flow formed by the first fan 21 can flow directly downward into the air duct formed between the cooking cavity and the air frying container 12, thereby preventing the air flow from entering the air frying container 12 from the top of the air frying container 12, and ensuring that the air flow between the air duct and the air container 12 forms a circulation.
[0081] According to some embodiments of the present invention, the side of the air-frying container 12 facing the first fan 21 has an opening, and the air guide cover 13 is covered on the opening of the air-frying container 12. By providing the opening on the air-frying container 12, it is convenient to take and put food. By covering the air guide cover 13 on the opening of the air-frying container 12, it can be prevented that the wind generated by the first fan 21 directly enters the air-frying container 12 through the opening.
[0082] like Figure 3 and Figure 4 as well as Fig.12 and Fig.13 As shown, according to some embodiments of the present invention, the middle portion of the air guide cover 13 has a vent 131 to connect the inner cavity of the air frying container 12 with the cooking cavity, and the orthographic projection of the vent 131 in a plane perpendicular to the rotation axis of the first fan 21 is located within the range of the area swept by the first fan 21 during rotation, further preventing the airflow from entering the air frying container 12 from the vent 131, thereby ensuring that the airflow between the air duct and the air container 12 forms a circulation.
[0083] According to some embodiments of the present invention, the first fan 21 is located directly above the central axis of the air frying container 12, and the vent 131 is set at the center of the air guide cover 13. The opening area of the vent 131 is not larger than the area swept by the first fan 21 when rotating, thereby preventing the airflow from entering the air frying container 12 from the vent 131, thereby ensuring that the airflow between the air duct and the air container 12 forms a circulation.
[0084] According to some embodiments of the present invention, at least a portion of the outer surface of the air guide cover 13 gradually extends downward from the middle of the air guide cover 13 to the outer edge of the air guide cover 13, so that the airflow formed under the action of the first fan 21 can directly flow downward into the air duct formed between the cooking cavity and the air frying container 12.
[0085] like Figure 3 and Figure 4 As shown, in some embodiments, the upper surface of the air guide cover 13 is an inclined surface, and the angle α formed by the inclined surface and the horizontal plane is 10° to 60°. For example, α can be 10°, 30°, 50° or 60°, so as to better achieve the air guide effect. Of course, the upper surface of the air guide cover 13 can also form a curved surface (such as a convex curved surface) that gradually extends downward from the middle of the air guide cover 13 to the outer edge of the air guide cover 13.
[0086] According to some embodiments of the present invention, the minimum spacing between the air guide cover 13 and the first fan 21 is 1-12 mm. For example, the minimum spacing between the air guide cover 13 and the first fan 21 can be 1 mm, 6 mm, 10 mm, or 12 mm. The spacing between the air guide cover 13 and the first fan 21 cannot be too large. By limiting the above parameters, it can be ensured that most of the wind blown out by the first fan 21 is guided to the side air duct instead of entering the air blasting container 12 from the vent 131 of the air guide cover 13.
[0087] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the vent 131 is formed as a circular hole, and the ratio of the diameter d of the vent 131 to the maximum diameter D of the first fan 21 is 0 to 3 / 2. For example, d / D can be 1 / 2, 1 or 3 / 2, so that at least a part of the airflow formed by the first fan 21 can avoid the vent 131 and enter the air frying container 12 from the air hole 121 at the lower part of the air frying container 12 along the air duct.
[0088] like Figure 3 and Figure 4As shown, in some embodiments, the radius r of the vent 131 is smaller than the distance R1 between the outer edge of the blade of the first fan 21 and the center of the first fan 21 in the horizontal direction, and the radius r of the vent 131 is larger than the distance R2 between the inner edge of the blade of the first fan 21 and the center of the first fan 21 in the horizontal direction. By limiting the radius r of the vent 131 to meet the above conditions, at least a part of the airflow formed by the first fan 21 can avoid the vent 131 and enter the air frying container 12 from the air hole 121 at the lower part of the air frying container 12 along the air duct.
[0089] like Fig.13 As shown, according to some embodiments of the present invention, a convex portion is provided in the middle of the inner surface of the bottom wall of the air-frying container 12, and at least one air hole 121 passes through the convex portion. By providing the convex portion on the inner surface of the bottom wall of the air-frying container 12 and providing at least one air hole 121 on the convex portion, it is possible to avoid blocking the air hole 121 when a large amount of food is placed in the air-frying container 12, and at the same time guide the wind to ensure that the airflow in the air duct can smoothly enter the air-frying container 12 from the bottom air hole 121.
[0090] In some embodiments, the convex portion forms a flange 123 or a convex rib extending along the circumference of at least one air hole 121. The flange 123 or the convex rib is used to protect at least one air hole 121, thereby preventing food in the air frying container 12 from entering the air hole 121 and blocking the air hole 121.
[0091] In some specific embodiments, when the cooking appliance 100 is in the air-frying cooking mode, the motor 32 drives the first fan 21 to rotate, and the heating device 15 at the bottom of the cooking body 10 heats the cooking container 11. The cooking container 11 is usually made of a metal material of heat conduction or electromagnetic induction. The temperature of the cooking container 11 increases after being heated, and the airflow blown out by the first fan 21 flows downward into the air duct formed between the cooking cavity and the air-frying container 12 under the guidance of the air guide cover 13, and then reaches the bottom of the cooking container 11, and forms hot air after heat exchange with the high-temperature cooking container. The hot air rises through the air hole 121 in the middle of the air-frying container 12 and enters the air-frying container 12. The hot air cooks the food in the air-frying container 12, and then flows out from the vent 131 of the air guide cover 13 under the action of wind pressure, thereby completing a cycle of hot air baking of the food.
[0092] According to a further embodiment of the present invention, the cooking utensil 100 includes a cooking body 10 and a cover assembly 20, the cooking body 10 includes a cooking container 11, the cover assembly 20 is arranged on the cooking body 10, the cooking cavity is defined by the cooking container 11 and the cover assembly 20, and the heating device 15 is arranged on at least one of the cooking body 10 and the cover assembly 20.
[0093] In some embodiments, a first fan 21 is provided on the cover assembly 20, the heating device 15 is located at the bottom of the cooking container 11, the air hole 121 is located in the middle of the bottom wall of the air frying container 12, and the other wall surfaces of the bottom wall of the air frying container 12 except the air hole 121 are closed surfaces.
[0094] Since the heating device 15 is arranged at the bottom of the cooking container 11, the bottom of the cooking container 11 is a heated high temperature area. In order to ensure that the wind in the air duct fully exchanges heat with the bottom of the cooking container 11, an air hole 121 is arranged in the middle of the bottom wall of the air frying container 12, and the other wall surfaces of the bottom wall of the air frying container 12 except the air hole 121 are set as closed surfaces. When the wind passes through the space between the bottom of the cooking container 11 and the bottom of the air frying container 12, it can fully exchange heat with the bottom of the cooking container 11, so as to form hot air and then flow upward from the air hole 121 into the inside of the air frying container 12 to bake food.
[0095] Compared with the related art in which a plurality of air holes arranged at intervals are provided on the entire bottom surface of the air-frying container, the present embodiment can prevent the air from directly entering the air-frying container 12 from the small holes on the side of the air-frying container 12 after reaching the space between the bottom of the cooking container 11 and the bottom of the air-frying container 12 without sufficient heat exchange with the cooking container 11, resulting in uneven cooking of the food on the side and the food in the middle, thereby ensuring the uniformity of food cooking and improving the cooking effect.
[0096] According to some embodiments of the present invention, the air-frying container 12 has an air hole 121. When the air-frying container 12 is placed in the cooking cavity, an air duct is defined between the air-frying container 12 and the cooking cavity, and the air duct is connected to the inner cavity of the air-frying container 12 through the air hole 121.
[0097] Thus, by providing the air holes 121, it is convenient to better cook the food in the inner cavity of the air frying container 12. For example, in the air frying cooking mode, when the air frying container 12 is used to fry the food in its inner cavity, the air holes 121 can facilitate the hot air to flow between the air duct and the inner cavity of the air frying container 12, thereby improving the frying and cooking effect of the food in the air frying container 12.
[0098] In some embodiments, the cooking appliance 100 further includes a support 14 detachably disposed in the cooking cavity for supporting the air-frying container 12 and separating the air-frying container 12 from the cooking cavity.
[0099] This not only facilitates stably placing the air-frying container 12 in the cooking cavity, improving the reliability of the placement of the air-frying container 12, but also facilitates defining an isolation gap between the outer bottom wall of the air-frying container 12 and the inner bottom wall of the cooking cavity, so as to better cook the food in the air-frying container 12. For example, when the air-frying container 12 is placed in the cooking cavity for air-frying cooking, the isolation gap can assist in guiding the hot air convection in the cooking cavity, strengthen the convection intensity of the hot air in the cooking cavity, and improve the baking and frying effect of the food in the air-frying container 12.
[0100] According to a further embodiment of the present invention, the cooking appliance 100 includes a cooking body 10 and a cover assembly 20, the cooking body 10 includes a cooking container 11, the cover assembly 20 is arranged on the cooking body 10, the cooking cavity is defined by the cooking container 11 and the cover assembly 20, and the heating device 15 is arranged on at least one of the cooking body 10 and the cover assembly 20. The cover assembly 20 is connected to an air frying head 30, which is arranged on a side of the cover assembly 20 facing away from the cooking body 10, and the air frying head 30 is provided with a motor 32 for driving the first fan 21 to rotate.
[0101] Therefore, by setting the air-frying head 30 on the cover body assembly 20 and setting the motor 32 on the air-frying head 30, in one cooking mode, through the cooperation of the cooking body 10, the cover body assembly 20 and the air-frying head 30, the motor 32 is used to drive the first fan 21 to rotate to achieve the baking cycle cooking effect. In another cooking mode, the motor 32 can be controlled not to work, and cooking can be achieved through the cooperation of the cooking body 10 and the cover body assembly 20. The two cooking modes can be cooked in one body, and there is no need to switch back and forth between the cover body assembly 20 and the air-frying head 30. The operation is simple and the user experience is better.
[0102] In some embodiments, the motor 32 is provided with a first magnet 322 that rotates synchronously with its rotor, and the first fan 21 is provided with a second magnet 212, and the first magnet 322 is suitable for being attracted to the second magnet 212 to drive the first fan 21 to rotate when the motor 32 is working. By providing the first magnet 322 and the second magnet 212, it is not necessary to make a hole in the cover assembly 20 to directly connect the motor 32 to the first fan 21. By using the magnetic drive principle, the motor 32 can drive the first fan 21, which not only ensures the structural integrity and strength of the cover assembly 20, but also reduces the processing steps of the cover assembly 20.
[0103] In some examples, the first fan 21 includes an inner ring and a fan blade, one end of the fan blade is connected to the inner ring and the other end extends outward, the second magnet 212 is arranged in the inner ring, and the middle of the inner ring has an assembly hole, and the opening area of the vent 131 is not less than the area of the inner ring, ensuring that at least a part of the airflow formed by the first fan 21 can avoid the vent 131 and smoothly enter the air frying container 12 from the bottom air hole 121.
[0104] In some embodiments, the cooking device 1000 includes a baking cooking mode and a steaming cooking mode. In the baking cooking mode, the cover assembly 20 covers the cooking body 10, and the air frying head 30 is arranged on the cover assembly 20, the heating device 15 heats and the motor 32 drives the first fan 21 to rotate to generate hot air. In the steaming cooking mode, the cover assembly 20 covers the cooking body 10, and the air frying head 30 is allowed to be separated from the cover assembly 20, and the heating device 15 heats the food in the cooking cavity. Among them, the steaming cooking mode includes steaming cooking, rice cooking, stewing cooking and pressure cooking.
[0105] Therefore, the cooking utensil 100 of this embodiment can achieve cooking in the baking cooking mode through the cooperation of the cooking body 10, the cover assembly 20 and the air-frying head 30, and using the motor 32 to drive the first fan 21 to rotate. It can also achieve cooking in the steaming cooking mode by controlling the motor 32 on the air-frying head 30 not to work and achieving cooking through the cooperation of the cooking body 10 and the cover assembly 20. The two cooking modes can be cooked in one body without switching back and forth between the cover assembly 20 and the air-frying head 30. The operation is simple and the user experience is better.
[0106] like Figure 1-Figure 4 As shown, the cooking appliance 100 according to some further embodiments of the present invention includes a cooking body 10 , a cover assembly 20 , a fan assembly and a heating device 15 .
[0107] The cover assembly 20 can be covered with and separated from the cooking body 10. When the cover assembly 20 is covered on the cooking body 10, a cooking cavity is defined between the cover assembly 20 and the cooking body 10. The fan assembly includes a first fan 21 and a motor 32. The motor 32 is used to drive the first fan 21 to rotate. The fan assembly is arranged on the cover assembly 20 or the cooking body 10. The heating device 15 is arranged on the cooking body 10 or the cover assembly 20, and is used to heat the food in the cooking cavity.
[0108] The motor 32 is provided with a magnetic part, and the first fan is a magnetic fan. When the motor 32 is working, the magnetic fan is driven to rotate by the magnetic part.
[0109] According to the cooking appliance 100 of the embodiment of the present invention, a magnetic fan is driven by arranging a magnetic part on the motor 32. There is no need to open a hole in the cover assembly 20 or the cooking body 10 to directly connect the motor 32 to the first fan 21. The motor 32 can drive the first fan 21 by utilizing the magnetic drive principle, which not only ensures the structural integrity and structural strength of the cover assembly 20 or the cooking body 10, but also reduces the processing steps of the cover assembly 20 or the cooking body 10.
[0110] According to some embodiments of the present invention, the cooking appliance 100 includes a baking cooking mode and a steaming cooking mode, and the cover assembly 20 covers the cooking body 10. In the baking cooking mode, the heating device 15 heats and the motor 32 drives the first fan 21 to rotate to generate hot air. In the steaming cooking mode, a sealed space is formed in the cooking cavity.
[0111] Therefore, by arranging the first fan 21 and the motor 32 on the cover body assembly 20, in the baking cooking mode, the motor 32 can be used to drive the first fan 21 to rotate, and the heating device 15 can be used to heat the cooking cavity to achieve cooking. In the steaming cooking mode, the heating device 15 can be used to heat the cooking cavity to achieve cooking. Both cooking modes are possible, with simple operation and better user experience.
[0112] That is to say, the cooking appliance 100 of the present embodiment can perform both baking cooking and steaming cooking. Since steaming cooking usually requires the cooking cavity to be sealed, the magnetic part of the motor 32 is used to drive the first fan 21, thereby avoiding the need to open a hole in the cover assembly 20 for passing the motor shaft, thereby ensuring the sealing of the cooking cavity in the steaming mode. In particular, when the steaming mode is a high-pressure cooking mode, good sealing is particularly important.
[0113] According to some embodiments of the present invention, the magnetic member is a first magnet 322, and the magnetic fan includes a second magnet 212. The first magnet 322 is suitable for being attracted to the second magnet 212, thereby driving the first fan 21 to rotate when the motor 32 is working. In other words, the first magnet 322 and the second magnet 212 are attracted to each other, so that the second magnet 212 can move synchronously with the first magnet 322, thereby realizing that the motor 32 drives the first fan 21 to rotate.
[0114] Therefore, by setting the first magnet 322 and the second magnet 212, there is no need to open a hole in the cover body assembly 20 to directly connect the motor 32 to the first fan 21. The motor 32 can drive the first fan 21 by utilizing the magnetic drive principle, which not only ensures the structural integrity and structural strength of the cover body assembly 20, but also reduces the processing steps of the cover body assembly 20.
[0115] In addition, by providing the first magnet 322 and the second magnet 212, there is no need to open a hole in the cover body assembly 20 to directly connect the motor 32 to the first fan 21. The magnetic drive principle can be used to drive the first fan 21 by the motor 32, which not only reduces the processing steps of the cover body assembly 20, but also ensures the structural integrity and structural strength of the cover body assembly 20, and does not affect the sealing performance of the cooking cavity in the steaming and cooking mode. In particular, when the steaming and cooking mode is a high-pressure cooking mode, the sealing requirements are high and the sealing difficulty is great. If a hole is opened on the cover body assembly for the motor shaft to pass through, it will inevitably affect the sealing performance of the cover body assembly 20 during high-pressure cooking. In this embodiment, there is no need to open a hole in the cover body assembly 20, which better ensures the sealing performance of the cover body assembly 20.
[0116] In some embodiments, the first magnet 322 and the second magnet 212 are directly opposite to each other, the number of the first magnet 322 and the second magnet 212 are equal and the positions are one-to-one corresponding, and the first magnet 322 and the second magnet 212 have opposite poles facing each other.
[0117] For example, the number of the first magnet 322 and the number of the second magnet 212 are both one, and the first magnet 322 and the second magnet 212 attract each other, so that when the motor 32 and the first fan 21 are not directly connected, the motor 32 can still drive the first fan 21 to rotate when working, thereby simplifying the structure of the cover assembly 20.
[0118] For another example, the number of the first magnet 322 and the number of the second magnet 212 can be multiple, and the multiple first magnets 322 and the multiple second magnets 212 are attracted in a one-to-one correspondence, thereby further ensuring that the motor 32 can normally drive the first fan 21 to rotate.
[0119] In some optional embodiments, the number of the first magnets 322 and the number of the second magnets 212 are 2-4 respectively. For example, the number of the first magnets 322 and the second magnets 212 can be two or three respectively, and the poles of all the first magnets 322 are arranged in the same direction.
[0120] In some examples, the S poles of the first magnet 322 and the second magnet 212 are both facing upward and the N poles are both facing downward, so that the N pole of the first magnet 322 is directly opposite to the S pole of the second magnet and can be attracted to each other; in other examples, the N poles of the first magnet 322 and the second magnet 212 are both facing upward and the S poles are both facing downward, so that the S pole of the first magnet 322 is directly opposite to the N pole of the second magnet and can be attracted to each other, ensuring that the motor 32 can still drive the first fan 21 to rotate when it is not directly connected to the first fan 21.
[0121] like Figure 7-Figure 11As shown, in some other optional embodiments, the number of the first magnet 322 and the second magnet 212 are respectively more than three, for example, the number of the first magnet 322 and the second magnet 212 can be four or more, all of the first magnets 322 are arranged at intervals in a circumferential direction, and correspondingly, all of the second magnets 212 are arranged at intervals in a circumferential direction, and the poles of at least two adjacent first magnets 322 are arranged in opposite directions.
[0122] Specifically, one of the first magnets 322 has its S pole facing upward and its N pole facing downward, and the two first magnets 322 adjacent to the first magnet 322 have their N poles facing upward and their S poles facing downward; correspondingly, the second magnet 212 corresponding to its position has its S pole facing upward and its N pole facing downward, and the two second magnets 212 adjacent to the second magnet 212 have their N poles facing upward and their S poles facing downward.
[0123] like Figure 7 As shown, according to some embodiments of the present invention, a magnetic shielding member 35 is provided between the motor 32 and the first magnet 322. By providing the magnetic shielding member 35 between the motor 32 and the first magnet 322, the magnetic poles of the first magnet 322 can be prevented from affecting the rotation and service life of the motor 32.
[0124] In order to ensure that the first magnet 322 is positioned and installed on the motor 32, thereby ensuring that the first magnet 322 can rotate synchronously with the rotor of the motor 32, in an embodiment, the end surface of the rotor of the motor 32 has a first mounting recess 321, and the first magnet 322 is arranged in the first mounting recess 321.
[0125] Similarly, in order to ensure the installation reliability of the second magnet 212 on the first fan 21, thereby ensuring that the second magnet 212 can rotate synchronously with the first fan 21, in this embodiment, the side of the hub of the first fan 21 facing the motor 32 has a second mounting recess 211, and the second magnet 212 is arranged in the second mounting recess 211.
[0126] like Figure 4 As shown, according to some embodiments of the present invention, a mounting shaft 22 is provided on one side of the cover assembly 20 facing the cooking body 10, the mounting shaft 22 is plug-assembled or welded with the cover assembly 20, and the first fan 21 is rotatably provided on the mounting shaft 22. By providing the mounting shaft 22, the installation of the first fan 21 is facilitated.
[0127] In some embodiments, a bearing 28 is installed between the installation shaft 22 and the first fan 21 , and the first fan 21 is rotatably installed on the installation shaft 22 through the bearing 28 , thereby ensuring the rotation stability of the first fan 21 .
[0128] In some embodiments, a fastener 25 and a protective cover 23 located between the fastener 25 and the first fan 21 are provided on the installation shaft 22 , and the fastener 25 limits the axial position of the protective cover 23 .
[0129] Therefore, by providing the protective cover 23, not only can the first fan 21 be protected, but also the user can be prevented from accidentally touching the blades of the first fan 21 and scratching his fingers; by providing the fastener 25 on the mounting shaft 22, the protective cover 23 can be limited and fixed, and when the protective cover 23 needs to be removed for cleaning, the fastener 25 can be removed to remove the protective cover 23, which is simple to operate and easy to implement.
[0130] In some examples, a stopper 221 and a gasket 24 are further provided on the mounting shaft 22, the stopper 221 is provided close to the bearing 28, the gasket 24 is provided close to the fastener 25, and the protective cover 23 is located between the stopper 221 and the gasket 24. By providing the stopper 221 on the mounting shaft 22, the bearing 28 can be axially limited, and by providing the gasket 24, the protective cover 23 and the fastener 25 can be protected to prevent wear on the surface of the parts.
[0131] According to a further embodiment of the present invention, the fan assembly is arranged on the cover assembly 20, and the cover assembly 20 is connected to a frying head 30, which is arranged on a side of the cover assembly 20 facing away from the cooking body 10, and the motor 32 is arranged in the frying head 30.
[0132] Therefore, by setting an air-frying head 30 on the cover body assembly 20 and setting the motor 32 in the air-frying head 30, in the baking cooking mode, through the cooperation of the cooking body 10, the cover body assembly 20 and the air-frying head 30, and utilizing the magnetic drive principle, the motor 32 is used to drive the first fan 21 to rotate to achieve a baking cycle cooking effect. In the steaming cooking mode, the motor 32 can be controlled not to work, and cooking can be achieved through the cooperation of the cooking body 10 and the cover body assembly 20. The two cooking modes can be cooked in one body, and there is no need to switch back and forth between the cover body assembly 20 and the air-frying head 30. The operation is simple and the user experience is better.
[0133] In some embodiments, one of the air blasting head 30 and the cover assembly 20 has a positioning recess 27 , and the other of the air blasting head 30 and the cover assembly 20 has a positioning protrusion 33 , and the positioning protrusion 33 cooperates with the positioning recess 27 .
[0134] Specifically, Figure 7As shown, a positioning protrusion 33 protruding downward is provided at the bottom of the air-frying head 30, and a positioning recess 27 recessed downward is provided at the top of the cover assembly 20. The air-frying head 30 is engaged in the positioning recess 27 through the positioning protrusion 33, so that the air-frying head 30 is positioned and installed on the cover assembly 20, preventing the air-frying head 30 from shaking relative to the cover assembly 20 or detaching from the cover assembly 20 when the cooking utensil 100 is working, thereby ensuring that the cooking utensil 100 can work normally.
[0135] Therefore, by adopting a structure in which the positioning protrusion 33 cooperates with the positioning recess 27, the positioning installation of the air blasting head 30 on the cover assembly 20 can be achieved, ensuring the installation stability and reliability of the air blasting head 30 on the cover assembly 20, thereby ensuring that the air blasting head 30 can work normally.
[0136] like Figure 7 and Figure 8 As shown, in some examples, one side wall of the positioning protrusion 33 and the positioning recess 27 has a guide rib 331, and the other one of the positioning protrusion 33 and the positioning recess 27 has a guide groove (not shown in the figure), and the guide groove cooperates with the guide rib 331.
[0137] Therefore, by adopting a structure in which the guide rib 331 cooperates with the guide groove, it can be ensured that the central axis of the motor 32 in the air blasting head 30 coincides with the central axis of the first fan 21 on the cover assembly 20, thereby ensuring that the motor 32 can normally drive the first fan 21 to rotate.
[0138] It should be noted that, in order to further ensure the stability of the air-blasting head 30, a structure in which a plurality of guide ribs 331 and a plurality of guide grooves are matched one by one can be adopted. Figure 6 and Figure 7 As shown, the side wall of the positioning protrusion 33 is provided with a plurality of guide ribs 331 arranged at intervals along its circumference, each guide rib 331 extends in the up-down direction, and the side wall of the positioning recess 27 is provided with a plurality of guide grooves.
[0139] like Figure 3 and Figure 4 As shown, in some examples, the cover assembly 20 includes a metal cover 29 , and the metal cover 29 is provided with cover teeth that snap fit with the cooking body 10 , thereby ensuring the connection reliability and sealing between the metal cover 29 and the cooking body 10 .
[0140] Among them, the bottom wall of the positioning recess 27 is a part of the metal cover 29, the motor 32 is located above the metal cover 29, and the first fan 21 is located below the metal cover 29, that is, the metal cover 29 separates the motor 32 and the first fan 21. There is no need to open a hole in the metal cover 29 to directly connect the motor 32 to the first fan 21. The motor 32 can drive the first fan 21 by utilizing the magnetic drive principle, which not only ensures the structural integrity and structural strength of the metal cover 29, but also reduces the processing steps of the metal cover 29.
[0141] In some embodiments, the baking cooking mode is an air-frying cooking mode, and the steaming cooking mode is a high-pressure cooking mode. When the cooking appliance 100 is in the air-frying cooking mode, the cover assembly 20 covers the cooking body 10 and the air-frying head 30 is arranged on the cover assembly 20; when the cooking appliance is in the high-pressure cooking mode, the cover assembly 20 covers the cooking body 10 and the air-frying head 30 is allowed to be separated from the cover assembly 20.
[0142] That is, when the cooking device 100 is in the air-frying cooking mode, the cover assembly 20 covers the cooking body 10, and the air-frying head 30 is arranged on the cover assembly 20, the heating device 15 heats the cooking cavity, and the motor 32 drives the first fan 21 to rotate. When the cooking device 100 is in the high-pressure cooking mode, the cover assembly 20 covers the cooking body 10, and the air-frying head 30 is allowed to be separated from the cover assembly 20. Of course, the air-frying head 30 may not be separated from the cover assembly 20. In this cooking mode, the heating device 15 heats the cooking cavity, and the motor 32 in the air-frying head 30 is controlled not to work.
[0143] A specific embodiment of the cooking appliance 100 according to the present invention will be described in detail below with reference to the accompanying drawings.
[0144] The cooking appliance 100 according to one embodiment of the present invention includes a cooking body 10 , a cover assembly 20 and an air frying head 30 .
[0145] The cooking body 10 includes a housing, a cooking container 11 , an air frying container 20 , an air guide cover 13 , a bracket 14 and a heating device 15 .
[0146] In some examples, the outer shell can form an integral piece, and the cooking container 11 and the heating device 15 can both be arranged in the outer shell. The cooking container 11 can be detachably arranged in the outer shell and located above the heating device 15, so that the cooking container 11 and the heating device 15 are combined together and used in conjunction with the cover assembly 20 and the air frying head 30.
[0147] In other examples, the shell here may include a base and an outer cover, the base and the outer cover can be separately arranged, the heating device 15 is arranged on the base to form a heating base in combination, and the cooking container 11 is arranged in the outer cover, so that the cooking utensil 100 forms a three-section structure arranged in the up and down directions. Specifically, from top to bottom, they are: a cover body assembly 20 (or a combination structure A of the cover body assembly 20 and the air frying head 30), a combination structure B of the outer cover and the cooking container 11, etc., and a combination structure C of the base and the heating device 15, etc., and the three-part combination structure can be separately arranged.
[0148] The support 14 is detachably arranged at the bottom of the cooking container 11, and the empty frying container 20 is supported on the support 14, so that the outer wall surface of the empty frying container 20 is separated from the inner wall surface of the cooking container 11 to form an air duct, and the air guide cover 13 is arranged on the top of the empty frying container 20 and has a vent 131. The bottom wall of the empty frying container 12 has an air hole 121, and the inner cavity of the empty frying container 12 is connected to the air duct through the vent 131 and the air hole 121.
