Description

[0001] The present application claims priority to Chinese Patent Application No. 202520174457.8, filed on January 24, 2025, entitled "Air Fryer", and Chinese Patent Application No. 202422427658.2, filed on October 9, 2024, entitled "Cooking Appliance", the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of household appliances, in particular to a cooking appliance. BACKGROUND

[0003] There are various types of cooking appliances, one of which is a cooking device that uses hot air circulation and the oil of food itself to fry food. This type of cooking device is favored by consumers due to its green and healthy cooking concept. Common cooking devices of this type include air fryers and air ovens.

[0004] This type of cooking device can also be divided into single-pot cooking devices and double-pot cooking devices according to the number of pots. Some double-pot cooking devices in the related art arrange two pots in a top-and-bottom manner, and each pot is arranged with a burner.

[0005] When this type of cooking device dissipates heat during operation, air from the external environment usually enters the cooking device through a certain part of the cooking device, then successively passes around the two pots, carries away heat, and finally is discharged outside the cooking device. Since the air successively passes around the two pots, the temperature of the air becomes relatively high after passing around one pot, resulting in poor heat dissipation effect when the air passes around the other pot.

[0073] Figure 1 is a structural schematic diagram of a cooking appliance provided by an embodiment of the present application. As shown in Figure 1 , the cooking appliance includes a shell 10, a lower pot body 41 and an upper pot body 42, the lower pot body 41 and the upper pot body 42 are installed in the shell 10 and can be separated from the shell 10.

[0074] Figure 2 is a structural schematic diagram of a cooking appliance provided by an embodiment of the present application, Figure 2 at least the lower pot body 41 and the upper pot body 42 are omitted. As shown in Figure 2 , the cooking appliance further includes a partition plate 20 located in the shell 10, which divides the shell 10 into a lower cavity 10a and an upper cavity 10b.

[0075] Figure 3 is a structural schematic diagram of a cooking appliance provided by an embodiment of the present application, Figure 2 at least the lower pot body 41 and the upper pot body 42 are omitted. As shown in Figure 3 , the cooking appliance further includes a lower furnace head 31 and an upper furnace head 32.

[0076] The lower cavity 10a is located between the lower furnace head 31 and the bottom wall of the shell 10, and the lower furnace head 31 is located in the lower cavity 10a. The upper cavity 10b is located between the upper furnace head 32 and the partition plate 20, and the upper furnace head 32 is located in the upper cavity 10b. The shell 10 has a first air inlet 103, which communicates with the lower cavity 10a and / or the upper cavity 10b. That is, the first air inlet 103 communicates with at least one of the upper cavity 10b and the lower cavity 10a.

[0077] The cooking utensil needs to be cooled down during use. In the embodiment of the present application, the shell 10 is divided into an upper cavity 10b and a lower cavity 10a by the partition plate 20, and the first air inlet 103 is arranged on the shell 10, wherein the first air inlet 103 is in communication with at least one of the lower cavity 10a and the upper cavity 10b. This allows the lower furnace head 31 in the lower cavity 10a and the upper furnace head 32 in the upper cavity 10b to respectively introduce air from the first air inlet 103 for cooling down during work, so that the upper furnace head 32 and the lower furnace head 31 can be better cooled down, and the cooling effect of the cooking utensil is improved.

[0078] As shown in Figure 3 , the lower pot body 41 is located between the lower furnace head 31 and the bottom wall of the shell 10. The upper pot body 42 is located between the upper furnace head 32 and the partition plate 20. The lower furnace head 31 is used to heat the lower pot body 41 or the food material in the lower pot body 41, and the upper furnace head 32 is used to heat the upper pot body 42 or the food material in the upper pot body 42.

[0079] As an example, the shell 10 can also have a second air inlet 101 and a third air inlet 102, wherein the second air inlet 101 is in communication with the lower cavity 10a, and the third air inlet 102 is in communication with the upper cavity 10b.

[0080] The cooking utensil needs to be cooled down during use. The lower furnace head 31 in the lower cavity 10a can also be cooled down by the air entering through the second air inlet 101 during work, and the upper furnace head 32 in the upper cavity 10b can also be cooled down by the air entering through the third air inlet 102 during work, so as to further improve the cooling effect of the upper furnace head 32 and the lower furnace head 31.

[0081] Figure 4 is a structural schematic view of a lower furnace head provided by the present application. As shown in Figure 4 , the lower furnace head 31 includes a heating device 311, a first fan 312, a second fan 313, a reflector 314, and a motor (not shown).

[0082] The inner side of the reflector 314 refers to the side of the reflector 314 close to the lower pot body 41, and the outer side of the reflector 314 refers to the side of the reflector 314 away from the lower pot body 41. The heating device 311 and the first fan 312 are located on the inner side of the reflector 314, and the heating device 311 is located on the side of the first fan 312 away from the reflector 314. The second fan 313 and the motor are located on the outer side of the reflector 314. The first fan 312 and the second fan 313 are coaxially connected to the rotating shaft of the motor.

[0083] During the working process of the cooking appliance, the heater 311 generates heat, and the heat radiation generated by the heater 311 is partially directly radiated to the lower pot body 41 to heat the food material, and the other part is radiated to the reflecting cover 314 and then radiated to the lower pot body 41 to heat the food material. The first fan 312 promotes the air flow between the reflecting cover 314 and the lower pot body 41, so that the air between the reflecting cover 314 and the lower pot body 41 is heated, and finally the temperature of the food material is increased.

[0084] The second fan 313 performs heat dissipation on the outer side of the reflecting cover 314, so as to avoid that the temperature of the motor and other structures of the lower furnace head 31 is too high.

[0085] The side wall of the shell 10 has a pot placing entrance 10c. The pot placing entrance 10c can be provided in one-to-one correspondence with the upper pot body 42 and the lower pot body 41. The shell 10 can also have an air outlet 10d, and the air outlet 10d and the pot placing entrance 10c are located on opposite sides of the shell 10. The air outlet 10d can be provided in one-to-one correspondence with the upper furnace head 32 and the lower furnace head 31.

[0086] As shown in FIG. 1, Figure 4 The lower furnace head 31 can also include a fan cover 315, and the fan cover 315 has an opening for facilitating air intake. The fan cover 315 covers the outer side of the reflecting cover 314. The second fan 313 is located between the fan cover 315 and the reflecting cover 314, and the cavity between the fan cover 315 and the reflecting cover 314 is in communication with the air outlet 10d, so that the second fan 313 can exhaust the hot air from the air outlet 10d to reduce the temperature of the lower furnace head 31.

[0087] The structure of the upper furnace head 32 can refer to the structure of the lower furnace head 31, which will not be described here.

[0088] As an example, the first air inlet 103 is in communication with the upper cavity 10b and the lower cavity 10a. The air flow entering the shell 10 from the first air inlet 103 can flow upward from the partition plate 20 under the suction of the second fan 313 of the upper furnace head 32, so as to dissipate heat from the structure in the upper cavity 10b and improve the heat dissipation effect in the upper cavity 10b. Another part can be sucked by the second fan 313 of the lower furnace head 31 in a shorter path, and the temperature of this part of air is lower than that of the air flowing through the space between the lower cooking bin body 61 and the side wall of the shell 10, which can better dissipate heat from the lower furnace head 31 and the circuit structure near the lower furnace head 31, and further improve the heat dissipation effect.

[0089] Figure 5 is a disassembly structure schematic diagram of a cooking appliance provided by an embodiment of the present application, Figure 5 in which at least the lower pot body 41 and the upper pot body 42 are omitted, and part of the shell 10 is omitted. As shown in FIG. 1, Figure 5As shown, the cooking appliance may further include a lower cooking chamber 61 and an upper cooking chamber 62. The lower cooking chamber 61 is located in the lower cavity 10a and has a gap between it and the inner wall of the shell 10; the lower pot body 41 is located in the lower cooking chamber 61. The upper cooking chamber 62 is located in the upper cavity 10b and has a gap between it and the inner wall of the shell 10; the upper pot body 42 is located in the upper cooking chamber 62.

[0090] The lower cooking chamber 61 can be connected to the reflector 314 of the lower burner 31 to form a chamber for accommodating the lower pot 41; the upper cooking chamber 62 can be connected to the reflector 314 of the upper burner 32 to form a chamber for accommodating the upper pot 42.

[0091] Because there is a gap between the lower cooking chamber 61 and the inner wall of the shell 10, this gap helps to reduce heat exchange between the lower cooking chamber 61 and the shell 10, thus acting as insulation. Therefore, during the operation of the cooking appliance, the temperature of the shell 10 will not become too high, thereby reducing the risk of burns. Similarly, the gap between the upper cooking chamber 62 and the inner wall of the shell 10 also prevents the temperature of the shell 10 from becoming too high, reducing the risk of burns.

[0092] like Figure 5 As shown, the cooking appliance also includes a first circuit board 51 and a second circuit board 52, wherein the first circuit board 51 is located between the lower burner 31 and the partition 20. The second circuit board 52 is located between the upper burner 32 and the top wall of the housing 10.

[0093] Cooking appliances typically contain electronic components, such as circuit boards. The first circuit board 51 and the second circuit board 52 in this embodiment can be any circuit board within the cooking appliance.

[0094] As an example, the first circuit board 51 can be electrically connected to the lower burner head 31 to control its operation. For example, the first circuit board 51 is electrically connected to the heater 311 and motor in the lower burner head 31; the second circuit board 52 can be electrically connected to the upper burner head 32 to control its operation. For example, the second circuit board 52 is electrically connected to the heater 311 and motor in the upper burner head 32.

[0095] The first circuit board 51 is arranged between the lower furnace head 31 and the partition plate 20, so that the first circuit board 51 is close to the second fan 313 in the lower furnace head 31, and heat dissipation of the first circuit board 51 is performed by using the air flow generated by the second fan 313 in the lower furnace head 31, so as to avoid that the temperature of the first circuit board 51 is too high. The second circuit board 52 is arranged between the upper furnace head 32 and the top wall of the shell 10, so that the second circuit board 52 is close to the second fan 313 in the upper furnace head 32, and heat dissipation of the second circuit board 52 is performed by using the air flow generated by the second fan 313 in the upper furnace head 32, so as to avoid that the temperature of the second circuit board 52 is too high.

[0096] In some examples, the second air inlet 101 is located at at least one of the bottom wall of the shell 10, the side wall of the shell 10, and the connection between the bottom wall and the side wall of the shell 10.

[0097] In the process of working of the cooking appliance, air can enter into the shell 10 through the second air inlet 101, for example, into the gap between the lower cooking cavity body 61 and the shell 10. The air flows through the gap between the lower cooking cavity body 61 and the shell 10 under the action of the second fan 313 of the lower furnace head 31, can dissipate heat of the lower furnace head 31, and can also take away part of the heat of the lower cooking cavity body 61 transferred to the shell 10, so as to reduce the temperature of the shell 10 and avoid that the outer surface of the shell 10 is scalding. The position of the arrangement of the second air inlet 101 is different, and the path of the air flow flowing in the shell 10 is also different. The second air inlet 101 can be arranged according to the heat distribution in the lower cavity 10a to further improve the heat dissipation effect.

[0098] As an example, as shown in Figure 3 As an example, the cooking appliance can include a plurality of fourth air inlet holes 1011, and the plurality of fourth air inlet holes 1011 are distributed on the bottom wall of the shell 10.

[0099] Figure 6 is a schematic diagram of a partial internal structure of a cooking appliance provided by an embodiment of the present application. Figure 6 In the figure, the direction of the air flow in the shell 10 is schematically shown by arrows. As shown in Figure 6 In the process of working of the cooking appliance, air can enter into the shell 10 from the fourth air inlet hole 1011 located on the bottom wall of the shell 10. The air flows in the shell 10 to take away heat, for example, under the action of the second fan 313 of the lower furnace head 31, the air flow flows along the gap between the bottom wall of the shell 10 and the lower cooking cavity body 61 to the gap between the side wall of the shell 10 and the lower cooking cavity body 61, and then flows upward to the second fan 313 and is discharged through the air outlet 10d. The air flow enters into the shell 10 from the bottom position of the shell 10, can dissipate heat of a larger range in the lower cavity 10a.

[0100] Figure 7 is another side view of the cooking appliance provided by an embodiment of the present application. As shown in Figure 7 the second air inlet 101 also includes a second air inlet hole 1012. In this example, the cooking appliance can include a plurality of second air inlet holes 1012 located at the connection between the bottom wall and the side wall of the housing 10. The plurality of second air inlet holes 1012 are distributed around the bottom wall of the housing 10.

[0101] The air enters the housing 10 from the fourth air inlet hole 1011 and is discharged from the air outlet 10d, and the path is long. During the flow of the air, the temperature gradually increases, which leads to a gradual decrease in the heat dissipation effect. In this example, by arranging a plurality of second air inlet holes 1012 at the connection between the bottom wall and the side wall of the housing 10, a portion of air with a lower temperature can be introduced again from the second air inlet hole 1012, which reduces the temperature of the air flow in the gap between the side wall of the housing 10 and the lower cooking chamber body 61, and is conducive to improving the heat dissipation effect.

[0102] In this example, by distributing the plurality of second air inlet holes 1012 around the bottom wall of the housing 10, the air can enter the gap between the side wall of the housing 10 and the lower cooking chamber body 61 from multiple directions, further improving the heat dissipation effect.

[0103] As shown in Figure 7 the outer side wall of the housing 10 also has a second groove 104 extending along the connection between the bottom wall and the side wall of the housing 10. At least part of the second air inlet hole 1012 is located in the second groove 104. In this example, the plurality of second air inlet holes 1012 are all located in the second groove 104.

[0104] By arranging the second groove 104 on the outer side wall of the housing 10 and arranging the second air inlet hole 1012 in the second groove 104, the second air inlet hole 1012 can be hidden, making the external structure of the housing 10 more beautiful. In addition, arranging the second air inlet hole 1012 in the second groove 104 can also reduce the risk of the second air inlet hole 1012 being blocked by foreign matter, ensuring the unobstructedness of the second air inlet hole 1012.

[0105] In some examples, the third air inlet 102 is located at at least one of the side wall of the housing 10, the connection between the side wall and the top wall of the housing 10.

[0106] During the operation of the cooking appliance, air can enter the interior of the housing 10 via the third air inlet 102, for example into the gap between the upper cooking chamber body 62 and the housing 10. The air flows through the gap between the upper cooking chamber body 62 and the housing 10 under the action of the second fan 313 of the upper burner 32, can dissipate heat from the upper burner 32, and can also take away part of the heat transferred from the upper cooking chamber body 62 to the housing 10, thereby reducing the temperature of the housing 10 and avoiding the outer surface of the housing 10 being scalding hot. The third air inlet 102 is arranged at different positions, and the path of the air flow in the housing 10 is also different. The third air inlet 102 can be arranged according to the heat distribution in the upper cavity 10b to further improve the heat dissipation effect.

[0107] Figure 8 is an enlarged view of A in Figure 3 . As shown in Figure 8 , the third air inlet 102 includes a third air inlet hole 1021. In this example, the cooking appliance can include a plurality of third air inlet holes 1021, which are located at the connection between the side wall and the top wall of the housing 10.

[0108] Arranging the third air inlet hole 1021 at the connection between the side wall and the top wall of the housing 10 can make the third air inlet hole 1021 closer to the upper burner 32 and the second circuit board 52, and the cold air entering the housing 10 from the third air inlet hole 1021 can better dissipate heat from the upper burner 32 and the second circuit board 52.

[0109] As an example, the plurality of third air inlet holes 1021 are distributed along the same side edge of the top wall of the housing 10.

[0110] Figure 9 is a schematic view of a partial internal structure of a cooking appliance provided by an embodiment of the present application. Figure 9 in Figure 9 , the direction of the air flow in the housing 10 is schematically shown by arrows. As shown in , the plurality of third air inlet holes 1021 are arranged at the same side edge of the top wall of the housing 10, so that during the operation of the cooking appliance, a stronger air flow can be formed at the side edge of the top wall for heat dissipation, which can provide heat dissipation for some devices that need good heat dissipation.

[0111] In this example, the second circuit board 52 is arranged adjacent to the third air inlet hole 1021, for example, between the third air inlet hole 1021 and the opening of the fan cover 315 of the upper burner 32, so that the second circuit board 52 can be well cooled.

[0112] Figure 8As shown, the outer side wall of the shell 10 further has a third groove 105 extending along the connection between the top wall and the side wall of the shell 10. At least part of the third air inlet hole 1021 is located in the third groove 105. In the present example, the plurality of third air inlet holes 1021 are all located in the third groove 105.

[0113] By arranging the third groove 105 on the outer side wall of the shell 10 and arranging the third air inlet hole 1021 in the third groove 105, the third air inlet hole 1021 can be hidden, and the external structure of the shell 10 is more beautiful. In addition, arranging the third air inlet hole 1021 in the third groove 105 can also reduce the risk of the third air inlet hole 1021 being blocked by foreign matter, and ensure the smoothness of the third air inlet hole 1021.

[0114] As an example, the first air inlet 103 can be located on one side or the peripheral side of the partition 20.

[0115] Arranging the first air inlet 103 on one side of the partition 20 allows air to enter the shell 10 from a specific direction. Arranging the first air inlet 103 on the peripheral side of the partition 20 allows air to enter the shell 10 from multiple directions, which is beneficial to improve the cooling effect.

[0116] Figure 10 is an enlarged view of B in Figure 3 As shown in Figure 10 The first air inlet 103 includes a plurality of first air inlet holes 1031 distributed along the opposite side edges of the partition 20.

[0117] Figure 11 is a schematic view of a partial internal structure of a cooking appliance provided by an embodiment of the present application. Figure 11 in which the direction of the air flow in the shell 10 is schematically shown by arrows. As shown in Figure 11 The air flow entering the shell 10 from the first air inlet hole 1031 can flow upwards from the partition 20 under the action of the second fan 313 of the upper burner head 32 to dissipate heat from the structure in the upper cavity 10b. Another part is sucked in by the second fan 313 of the lower burner head 31 to dissipate heat from the structure, such as the first circuit board 51, in the lower cavity 10a.

[0118] Arranging the plurality of first air inlet holes 1031 on the opposite side edges of the partition 20 allows the air flow introduced through the first air inlet hole 1031 to flow from both sides of the upper pot body 42, which has a larger heat dissipation area.

[0119] In the present example, since the first air inlet 103 is in communication with both the upper cavity 10b and the lower cavity 10a, it is possible that some of the air flowing between the lower cooking cavity 61 and the side wall of the housing 10 will enter the upper cavity 10b, and this air is at a higher temperature, which is not conducive to heat dissipation of the structure in the upper cavity 10b. Arranging the first air inlets 1031 on the opposite side edges of the partition 20 makes it possible for air flow to exist only at the opposite side edges of the partition 20, which is conducive to reducing the influence of the air in the lower cavity 10a on the heat dissipation effect of the upper cavity 10b.

[0120] As shown in Figure 10 The outer side wall of the housing 10 also has a first recess 106 extending along the side edge of the partition 20. At least part of the first air inlet 103 is located in the first recess 106. In the present example, the first air inlets 1031 are located in the first recess 106.

[0121] By arranging the first recess 106 on the outer side wall of the housing 10 and arranging the first air inlets 1031 in the first recess 106, the first air inlets 1031 can be hidden, making the external structure of the housing 10 more aesthetically pleasing. In addition, arranging the first air inlets 1031 in the first recess 106 can also reduce the risk of the first air inlets 1031 being blocked by foreign matter, ensuring the unobstructed flow of the first air inlets 1031.

[0122] In some examples, the partition 20 is connected to the side wall where the pot placing opening 10c is located, and the first air inlet 103 is located on the side wall adjacent to the side wall where the pot placing opening 10c is located.

[0123] The partition 20 can support the structure in the upper cavity 10b on one hand, and connecting the partition 20 to the side wall where the pot placing opening 10c is located can separate the upper cavity 10b from the lower cavity 10a at this location to prevent air flow in the lower cavity 10a from entering the upper cavity 10b at this location, which affects the heat dissipation performance of the upper cavity 10b.

[0124] Exemplarily, the partition 20 can have a plurality of reinforcing ribs arranged in a staggered manner to improve the structural strength of the partition 20 and more stably support the structure in the upper cavity 10b.

[0125] As shown in Figures 11 to 21As shown, this application embodiment provides a cooking appliance, including: a housing 10 with an exhaust vent 10d; a partition 20 located inside the housing 10, dividing the housing 10 into an upper cavity 10b and a lower cavity 10a, the upper cavity 10b including a first ventilation channel 110, the lower cavity 10a including a second ventilation channel 120, the partition 20 having a first air inlet 103 communicating with the outside, the first air inlet 103 communicating with the first ventilation channel 110 and the second ventilation channel 120; and a fan assembly 30 disposed inside the housing 10, used to drive the airflow in the first ventilation channel 110 and the second ventilation channel 120 to flow out from the exhaust vent 10d.

[0126] Cooking utensils can include height, length, and width, and these three directions are perpendicular or nearly perpendicular to each other. The length direction can be the direction the cooking utensil faces towards the user, and the width direction can be the side of the cooking utensil.

[0127] The housing 10 can serve as an outer shell for the cooking appliance, providing structural support and protection for the working parts inside. The housing 10 can be made of heat-resistant materials, such as stainless steel or thermoplastic.

[0128] The housing 10 is provided with an exhaust vent 10d that communicates with the outside.

[0129] like Figure 13 As shown, the partition 20 is located inside the shell 10, dividing the internal space of the shell 10 into an upper cavity 10b and a lower cavity 10a. The upper cavity 10b and lower cavity 10a are used to accommodate the upper pot body 42 and the lower pot body 41, respectively. The upper cavity 10b and lower cavity 10a can be arranged along the height direction.

[0130] It is understandable that in a kitchen environment where cooking appliances are used, vertical space is often easier to utilize than horizontal space. The upper cavity 10b and lower cavity 10a are arranged along the vertical direction, which allows for better utilization of the kitchen's vertical space without increasing the countertop area occupied by the cooking appliances. Compared to an arrangement where the upper cavity 10b and lower cavity 10a are arranged along the length direction, the vertical arrangement saves countertop space in the cooking appliance usage environment, making it more conducive to improving the space utilization of the kitchen environment.

[0131] like Figure 11 and Figure 12 As shown, the cooking appliance includes an upper pot body 42 and a lower pot body 41. The upper pot body 42 is detachably disposed in the upper cavity 10b, and the lower pot body 41 is detachably disposed in the lower cavity 10a. The upper pot body 42 may include a first cooking space 1201 for accommodating food ingredients, and the lower pot body 41 may include a second cooking space 1301 for accommodating food ingredients.

[0132] It is worth noting that the cooking utensil is configured with the upper pot body 42 and the lower pot body 41, which can be more suitable for the scene of cooking multiple food materials at a time. In this way, different types of food materials can be placed in the upper pot body 42 and the lower pot body 41 respectively and cooking can be completed in the relatively independent first cooking space 1201 and the second cooking space 1301. Different types of food materials will not cause odor mixing and adhesion, so that the user can cook different food materials at the same time, enriching the use scene of the cooking utensil.

[0133] As shown in Figure 13 The first ventilation channel 110 can be used for heat dissipation. It can be understood that the upper pot body 42 is filled with hot air, which will generate high temperature. This high temperature will be conducted to the outermost shell 10 of the cooking utensil, causing the temperature of the shell 10 to continuously rise, which will cause the user to be scalded or the shell to be aged, and will also affect the working performance of the electrical components in the upper cavity 10b. Therefore, the first ventilation channel 110 is arranged in the upper cavity 10b to quickly dissipate the heat energy in the first cooking space 1201 (specifically, the space other than the first cooking space 1201) to the external environment, so as to avoid the above safety problems.

[0134] As shown in Figure 13 The second ventilation channel 120 can be used for heat dissipation. It can be understood that the lower pot body 41 is filled with hot air, which will generate high temperature. This high temperature will be conducted to the outermost shell 10 of the cooking utensil, causing the temperature of the shell 10 to continuously rise, which will cause the user to be scalded or the shell to be aged, and will also affect the working performance of the electrical components in the lower cavity 10a. Therefore, the second ventilation channel 120 is arranged in the lower cavity 10a to quickly dissipate the heat energy in the second cooking space 1301 (specifically, the space other than the second cooking space 1301) to the external environment, so as to avoid the above safety problems.

[0135] As shown in Figure 14 The first air inlet 103 is communicated with the first ventilation channel 110 and the second ventilation channel 120 to provide cold air to the first ventilation channel 110 and the second ventilation channel 120, so as to exhaust the hot air in the first ventilation channel 110 and the second ventilation channel 120 from the upper cavity 10b and the lower cavity 10a. In this way, the partition plate 20 not only separates the shell 10 into the upper cavity 10b and the lower cavity 10a to prevent the food materials in the upper pot body 42 and the lower pot body 41 from mixing odor, but also can provide cold air to the first ventilation channel 110 and the second ventilation channel 120 for heat dissipation at the same time, thereby simplifying and optimizing the structure of the cooking utensil, and making the structure of the cooking utensil more compact.

[0136] In addition, the partition 20 can also reduce heat transfer between the upper cavity 10b and the lower cavity 10a, so as to ensure that the temperature of each accommodation cavity is within a controllable and set range.

[0137] The fan assembly 30 is arranged in the shell 10, and the fan assembly 30 can disturb airflow. When the fan assembly 30 rotates, cold air can be quickly sucked into the first ventilation channel 110 and the second ventilation channel 120 from the first air inlet 103, and hot air in the first ventilation channel 110 and the second ventilation channel 120 can be quickly discharged from the air outlet 10d, thereby improving the overall heat dissipation efficiency of the cooking appliance.

[0138] Thus, the cooking appliance provided by the embodiment can realize simultaneous cooking of different food materials in two independent accommodation cavities by separating the shell 10 into the upper cavity 10b and the lower cavity 10a by the partition 20, thereby improving the use convenience of the cooking appliance. Meanwhile, the first ventilation channel 110 and the second ventilation channel 120 are arranged in the upper cavity 10b and the lower cavity 10a respectively, and the fan assembly 30 cooperates to effectively realize heat dissipation inside the cooking appliance, thereby ensuring the stability and safety of the cooking appliance during long-time use. In addition, the first air inlet 103 enables cold air to smoothly enter the first ventilation channel 110 and the second ventilation channel 120, thereby reducing the temperature of the shell 10 and ensuring the use safety of the cooking appliance.

[0139] In some embodiments, as shown in Figure 13 and Figure 14 The cooking appliance further includes an upper cooking bin body 62. The upper cooking bin body 62 is arranged inside the shell 10, and the upper cooking bin body 62 surrounds an accommodation space to accommodate the upper pot body 42. The upper cooking bin body 62 and the shell 10 have a spacing along the radial direction of the cooking appliance.

[0140] In some embodiments, as shown in Figure 13 and Figure 14 The cooking appliance further includes a lower cooking bin body 61. The lower cooking bin body 61 is arranged inside the shell 10, and the lower cooking bin body 61 surrounds an accommodation space to accommodate the lower pot body 41. The lower cooking bin body 61 and the shell 10 have a spacing along the radial direction of the cooking appliance.

[0141] In some embodiments, as shown in Figure 13 The cooking appliance further includes a first reflector cover 60. The first fan cover 80 can be configured as a cover body.

[0142] The first reflector 60 can be disposed in the upper cavity 10b and cover the upper pot 42. The first reflector 60 can be indirectly connected to or abut the upper cooking chamber 62. As described above, the upper cooking chamber 62 has a spacing with the housing 10, so in the upper cavity 10b separated by the partition 20, the space outside the first reflector 60 and the upper cooking chamber 62, and inside the housing 10 forms the first ventilation channel 110.

[0143] In some embodiments, as shown in FIG. 1, the cooking appliance further includes a second reflector 70. The second fan cover 90 can be configured as a cover body. Figure 13

[0144] The second reflector 70 can be disposed in the lower cavity 10a and cover the lower pot 41. The second reflector 70 can be indirectly connected to or abut the lower cooking chamber 61. As described above, the lower cooking chamber 61 has a spacing with the housing 10, so in the lower cavity 10a separated by the partition 20, the space outside the second reflector 70 and the lower cooking chamber 61, and inside the housing 10 forms the second ventilation channel 120.

[0145] In this way, the first reflector 60 isolates the upper pot 42 from other spaces in the upper cavity 10b. The hot air is located in the first reflector 60 and the first cooking space 1201, thereby ensuring that the hot air circulates in the first cooking space 1201 covered by the first reflector 60, and that the hot air in the space outside the first reflector 60 is promptly discharged. The second reflector 70 isolates the lower pot 41 from other spaces in the lower cavity 10a. The hot air is located in the second reflector 70 and the second cooking space 1301, thereby ensuring that the hot air circulates in the second cooking space 1301 covered by the second reflector 70, and that the hot air in the space outside the second reflector 70 is promptly discharged, thereby balancing the cooking effect and use safety of the cooking appliance.

[0146] In some embodiments, as shown in FIG. 1, the partition 20 can include a heat insulation plate 201. The heat insulation plate 201 is located between the upper pot 42 and the lower pot 41. Figure 14

[0147] The heat insulation plate 201 can have heat insulation performance to prevent heat transfer between the upper cavity 10b and the lower cavity 10a. In addition, the heat insulation plate 201 also ensures that the upper cavity 10b and the lower cavity 10a are relatively isolated, and the food materials cooked in the upper cavity 10b and the lower cavity 10a do not produce cross odor.

[0148] In some embodiments, the heat insulation plate 201 can be made of high-temperature-resistant and heat-insulating materials, such as thermoset heat-insulating materials, to ensure the heat insulation performance of the heat insulation plate 201 in a high-temperature cooking environment, as well as the stability and durability of the heat insulation plate 201 itself. ​​

[0149] In some embodiments, the heat insulation plate 201 can be connected with the upper cooking cavity body 62, and the heat insulation plate 201 can be directly or indirectly connected with the shell 10, and the specific connection mode of the heat insulation plate 201 and the shell 10 is not limited in the embodiments of the present application.

[0150] In some embodiments, as shown in Figure 15 The edge of the heat insulation plate 201 can be provided with a first notch 2011a, and the first notch 2011a can form a channel with the inner wall of the shell 10, and the channel is respectively communicated with the first ventilation channel 110 and the first air inlet 103, so as to communicate the first air inlet 103 with the first ventilation channel 110.

[0151] In some embodiments, as shown in Figure 15 and Figure 16 The edge of the heat insulation plate 201 can be provided with a second notch 2011b, and the second notch 2011b can form a channel with the inner wall of the shell 10, and the channel is respectively communicated with the second ventilation channel 120 and the first air inlet 103, so as to communicate the first air inlet 103 with the second ventilation channel 120.

[0152] In some embodiments, as shown in Figure 15 and Figure 20 The partition plate 20 can include an annular grid 202. The annular grid 202 is arranged around the heat insulation plate 201, and a plurality of first air inlets 103 are formed on the annular grid 202. The annular grid 202 is recessed inwardly from the outer surfaces of the first housing and the second housing.

[0153] The annular grid 202 can be recessed inwardly from the outer surface of the shell 10, so that the first air inlets 103 provided on the annular grid 202 are not visible in appearance, and the first air inlets 103 have a stealth effect, so that the partition plate 20 has an integrated design appearance.

[0154] The plurality of first air inlets 103 are arranged at intervals along the circumference of the heat insulation plate 201, which can ensure the overall air intake of the partition plate 20, so that sufficient cold air can flow into the first ventilation channel 110 and the second ventilation channel 120.

[0155] In some embodiments, as shown in Figure 13 The first reflector 60 forms a first hot air cavity 601 for accommodating the first hot air assembly 40. That is, the first hot air assembly 40 is located above or on top of the upper pot body 42, the first hot air cavity 601 is communicated with the first cooking space 1201, and the hot air can enter the first cooking space 1201 from the top of the upper pot body 42, which is beneficial to the uniform cooking of the food. The first hot air assembly 40 can include a first heating device 401 and a first hot air fan 402.

[0156] In some embodiments, the first heater 401 may be a heat pipe, a microwave heater, or an infrared heater, etc.

[0157] In some embodiments, such as Figure 13 As shown, the second reflector 70 forms a second hot air cavity 701, which is used to accommodate the second hot air assembly 50. That is, the second hot air assembly 50 is located above or on top of the lower pot body 41, and the second hot air cavity 701 communicates with the second cooking space 1301, allowing hot air to enter the second cooking space 1301 from the top of the lower pot body 41, which is beneficial for the even cooking of the food. The second hot air assembly 50 may include a second heater 501 and a second hot air fan 502.

[0158] In some embodiments, the first heater 401 may be a heat pipe, a microwave heater, or an infrared heater, etc.

[0159] It is understandable that the first hot air assembly 40 is positioned above the upper pot body 42, allowing the high-temperature hot air generated by the first hot air assembly 40 to directly and evenly cover the interior of the first cooking space 1201. Furthermore, the hot air blown into the first cooking space 1201 from the top of the upper pot body 42 can circulate fully, ensuring a more uniform temperature distribution within the upper pot body 42. Compared to related technologies where some cooking appliances blow high-temperature hot air into the fryer from the side, blowing hot air from the top of the fryer effectively avoids the problem of localized overheating or undercooking of food due to concentrated heat. For example, food near the hot air device may be burnt, while food further away from the hot air device may be undercooked, thus improving the cooking quality and taste of the food.

[0160] The second hot air assembly 50 is positioned above the lower pot body 41, achieving the same technical effect as the first hot air assembly 40 positioned above the upper pot body 42, which will not be elaborated further here.

[0161] It is worth noting that in the cooking appliance provided in this application embodiment, the first hot air assembly 40 is disposed above the upper pot body 42, and the second hot air assembly 50 is disposed above the lower pot body 41. The first hot air assembly 40 and the second hot air assembly 50 disposed in this way can not only realize that the two frying buckets are heated independently, but also ensure that the food in each frying bucket can be heated evenly and achieve the same ideal cooking effect. This can avoid the problem of uneven cooking caused by the hot air not being able to enter the cooking space from the top of any frying bucket.

[0162] In some embodiments, the housing 10 includes a top cover 16, a first outer shell 11, and a second outer shell 12. The top cover 16 is connected to the first outer shell 11, and the upper cavity 10b is formed between the first outer shell 11, the top cover 16, and the partition 20. The lower cavity 10a is formed between the second outer shell 12 and the partition 20.

[0163] In some embodiments, as shown in Figure 15 The heat insulation plate 201 can include a first heat insulation part 2011 and a second heat insulation part 2012 arranged along the height direction. The first heat insulation part 2011 and the second heat insulation part 2012 are connected to each other.

[0164] In some embodiments, the first heat insulation part 2011 is connected to the upper cooking cavity body 62, and the edge of the first heat insulation part 2011 forms the first gap 2011a.

[0165] In some embodiments, the second heat insulation part 2012 is connected to the second housing 12, and the edge of the second heat insulation part 2012 forms the second gap 2012b.

[0166] In some embodiments, the first housing 11 is an appearance part of the cooking appliance, and the upper cooking cavity body 62 is arranged inside the first housing 11 and is used to enclose a space for placing the upper pot body 42. The first housing 11 and the upper cooking cavity body 62 have a spacing to form the first side channel 1011a.

[0167] As shown in Figure 13 and Figure 14 The first side channel 1011a has a certain length in the height direction and also extends a certain distance along the circumference of the upper pot body 42. The first air inlet 103 is arranged on the partition plate 20, and the cold air entering from the first air inlet 103 can flow in the first side channel 1011a and surround the upper pot body 42 to achieve heat exchange with the hot air on the side of the upper pot body 42.

[0168] In some embodiments, as shown in Figure 13 and Figure 14 The first side channel 1011a and the first top channel 1011b communicate to form the first ventilation channel 110.

[0169] The first side channel 1011a is used for heat exchange with the hot air radiated by the upper pot body 42, and the first top channel 1011b is used for heat exchange with the hot air radiated by the first hot air assembly 40. In this way, the first ventilation channel 110 can perform overall heat exchange on the upper cavity 10b, thereby ensuring the heat dissipation efficiency in the upper cavity 10b.

[0170] In some embodiments, the second housing 12 is an appearance part of the cooking appliance, and the lower cooking cavity body 61 is arranged inside the second housing 12 and is used to enclose a space for placing the lower pot body 41. The second housing 12 and the lower cooking cavity body 61 have a spacing to form the second side channel 1021a.

[0171] The second side channel 1021a has a certain length in the height direction, so as to realize heat exchange with the hot air around the lower pot body 41.

[0172] In some embodiments, as shown in Figure 13 and Figure 14 The second top channel 1021b is formed between the second reflector 70 and the partition plate 20, and the second side channel 1021a communicates with the second top channel 1021b to form the second ventilation channel 120.

[0173] The second side channel 1021a is used for heat exchange with the hot air radiated by the lower pot body 41, and the second top channel 1021b is used for heat exchange with the hot air radiated by the second hot air assembly 50, so that the second ventilation channel 120 can comprehensively exchange heat with the lower cavity 10a, thereby ensuring the heat dissipation efficiency in the lower cavity 10a.

[0174] In some embodiments, as shown in Figure 13 The fan assembly 30 includes a first motor 301 and a second motor 302. The first motor 301 is provided with a first heat dissipation fan 3011 on the periphery, and the first motor 301 is arranged in the first top channel 1011b.

[0175] The first heat dissipation fan 3011 is arranged on the first motor 301, and in the vertical direction, the cross-sectional area of the first heat dissipation fan 3011 covers at least part of the cross-sectional area of the first motor 301.

[0176] In some embodiments, the output end of the first motor 301 can be connected to the first hot air fan 402, so as to drive the hot air to circulate in the first cooking space 1201.

[0177] The first motor 301 is located in the first top channel 1011b of the first ventilation channel 110. In some embodiments, the first motor 301 includes a stator and a rotor, and the outer periphery of the rotor is connected with the first heat dissipation fan 3011 for disturbing air flow. When the first motor 301 drives the first hot air fan 402 to rotate, the first heat dissipation fan 3011 can also be driven to disturb the air flow at the same time, so that the air flow in the first ventilation channel 110 flows quickly, thereby improving the heat dissipation efficiency and the safety of the cooking appliance. In addition, by using one first motor 301, the hot air in the first cooking space 1201 can be disturbed to obtain balanced cooking effect, and the cold air can also be disturbed to improve the safety of the cooking appliance, thereby simplifying the structure of the cooking appliance.

[0178] It is worth noting that the first heat dissipation fan 3011 for disturbing air flow is connected to the outer periphery of the rotor of the first motor 301, which can further reduce the assembly height between the first motor 301 and the first heat dissipation fan 3011, thereby further miniaturizing the cooking device.

[0179] In some embodiments, the second motor 302 is provided with a second heat dissipation fan 3021 on the peripheral side of the second motor 302, and the second motor 302 is arranged in the second top channel 1021b.

[0180] The second heat dissipation fan 3021 is arranged on the second motor 302, and in the vertical direction, the cross-sectional area of the second heat dissipation fan 3021 covers at least part of the cross-sectional area of the second motor 302.

[0181] In some embodiments, the output end of the second motor 302 can be connected to the second hot air fan 502, so as to drive the hot air to circulate in the second cooking space 1301.

[0182] The second motor 302 is located in the second top channel 1021b of the second ventilation channel 120. In some embodiments, the second motor 302 includes a stator and a rotor, and the outer peripheral side of the rotor is connected with a second heat dissipation fan 3021 that disturbs air flow, so that when the second motor 302 drives the second hot air fan 502 to rotate, the second heat dissipation fan 3021 can be driven to disturb air flow at the same time, so that the air flow in the second ventilation channel 120 flows quickly, thereby improving the heat dissipation efficiency and improving the safety of the cooking appliance. In addition, by using one second motor 302, hot air in the second cooking space 1301 can be disturbed to obtain balanced cooking effect, and cold air can also be disturbed to improve the use safety of the cooking appliance, thereby simplifying the structure of the cooking appliance.

[0183] It is worth noting that the second heat dissipation fan 3021 that disturbs air flow is connected to the outer peripheral side of the rotor of the second motor 302, which can further reduce the assembly height between the second motor 302 and the second heat dissipation fan 3021, thereby further miniaturizing the cooking device. In some embodiments, as shown in Figure 13 and Figure 18 The cooking appliance further includes a third air inlet 102. The third air inlet 102 is arranged on the top cover 16 and is located at the connection between the first shell 11 and the top cover 16. The third air inlet 102 is communicated with the first ventilation channel 110.

[0184] The top cover 16 is connected to the top of the first shell 11, and the third air inlet 102 communicated with the first ventilation channel 110 is arranged on the top cover 16. The third air inlet 102 arranged on the top cover 16 provides another cold air inlet path for the first ventilation channel 110, so that more cold air can enter the first ventilation channel 110 to strengthen the heat dissipation effect of the first ventilation channel 110. The heat energy in the first ventilation channel 110 can be quickly dissipated, thereby improving the heat dissipation efficiency of the upper cavity 10b.

[0185] As shown in Figure 18As shown, the cover body 1063 can be an appearance piece, and the cover body 1063 is located at the top of the entire cooking utensil. The inner side of the cover body 1063, i.e. the side facing the upper cavity 10b, is provided with a decorative ring 1064 connected with the first shell 11, and the decorative ring 1064 is configured in a ring shape to improve the connection stability between the first shell 11 and the decorative ring 1064.

[0186] As shown in Figure 18 and Figure 19 , the outer edge of the decorative ring 1064 is closer to the center of the cover body 1063 than the outer edge of the cover body 1063, i.e. the decorative ring 1064 is recessed in appearance from the cover body 1063. By arranging the third air inlet 102 on the decorative ring 1064, the air inlet can be invisible in appearance, and the third air inlet 102 has a stealth effect, so that the top cover 16 has an integrated design appearance.

[0187] Further, the plurality of third air inlets 102 are arranged at intervals along the circumference of the cover body 1063, so that the cold air can enter the first ventilation channel 110 more evenly, further ensuring the heat dissipation effect of the first ventilation channel 110.

[0188] In some embodiments, as shown in Figure 17 and Figure 18 , the second shell 12 includes a base 1053, and the cooking utensil further includes a second air inlet 101 arranged on the base 1053. The second air inlet 101 is communicated with the second ventilation channel 120.

[0189] As shown in Figure 18 , the cold air entering the second side channel 1021a from the second air inlet 101 will flow from bottom to top under the disturbance of the second heat dissipation fan 3021, and then enter the second top channel 1021b to pass through the second motor 302 and then be discharged from the second ventilation channel 120.

[0190] In this way, even after passing through the second side channel 1021a, the cold air entering from the second air inlet 101 can still continue to be used for heat exchange of the second top channel 1021b, thereby improving the utilization rate of the cold air entering the lower cavity 10a from the second air inlet 101.

[0191] In addition, the arrangement of the second air inlet 101 provides another cold air inlet path for the second ventilation channel 120, so that more cold air can enter the second ventilation channel 120, and the heat energy in the second ventilation channel 120 can be quickly dissipated, thereby improving the heat dissipation efficiency of the lower cavity 10a.

[0192] In some embodiments, as shown in Figure 18As shown, the cooking utensil further comprises a first fan cover 80.

[0194] The cold air entering from the third air inlet 102 and the first air inlet 103 will enter the space between the first fan cover 80 and the top cover 16 under the disturbance of the first heat dissipation fan 3011, and then continue to flow into the space between the first fan cover 80 and the first reflecting cover 60 through the first opening 801 on the first fan cover 80, so as to pass through the first motor 301 and then be discharged from the first ventilation passage 110.

[0195] In some embodiments, as shown, Figure 18 The first fan cover 80 is provided with a first ventilation part 802 which extends into the space between the first outer shell 11 and the upper cooking chamber body 62, and a first passage is formed in the first ventilation part 802, the first passage being in communication with the first side passage 1011a and the first top passage 1011b.

[0196] In this way, the first fan cover 80 not only has the heat insulation effect to prevent excessive heat from being transferred to the top cover 16, but also can utilize the first fan cover 80 to connect the first side passage 1011a and the first top passage 1011b, thereby simplifying the number of structural components of the cooking utensil.

[0197] In some embodiments, the first reflecting cover 60 is arranged in the first fan cover 80, and the first fan cover 80 can also provide structural support for the first reflecting cover 60.

[0200] The cold air entering from the second air inlet 101 and the first air inlet 103 enters the space between the second fan cover 90 and the partition 20 under the disturbance of the second fan 3021, and then continues to flow into the space between the second fan cover 90 and the second reflecting cover 70 through the second opening 901 on the second fan cover 90, so as to pass through the second motor 302 and then be discharged from the second ventilation channel 120.

[0201] In some embodiments, as shown in Figure 18 The second fan cover 90 is provided with a second ventilation part 902 extending into the space between the second housing 12 and the lower cooking chamber body 61, and a second channel is formed in the second ventilation part 902, which communicates the second side channel 1021a and the second top channel 1021b.

[0202] In this way, the second fan cover 90 not only has the heat insulation effect to prevent excessive heat from being transferred to the top cover 16, but also can utilize the second fan cover 90 to communicate the second side channel 1021a and the second top channel 1021b, thereby simplifying the number of structural parts of the cooking appliance.

[0203] In some embodiments, the second reflecting cover 70 is arranged on the second fan cover 90, and the second fan cover 90 can also provide structural support for the second reflecting cover 70.
