Unless otherwise stated, the meaning of "multiple" is two or more.

[0041] Please refer to Figures 1 to 8 The embodiment of the present application provides a cooking appliance, which comprises a shell 10, the shell 10 has a containing space inside, the containing space is used for containing a frying barrel 20 or other working device. The shell 10 is also used for providing structural support for the frying barrel 20 or other working device.

[0042] The shell 10 can be made of heat-resistant material to ensure the safety of the cooking appliance.

[0043] As shown in Figure 2 and Figure 3 , the cooking appliance can comprise a frying barrel 20. The frying barrel 20 is detachably arranged in the containing space of the shell 10, and the frying barrel 20 is provided with a cooking space for accommodating food materials.

[0044] The frying barrel 20 is of an open structure, so as to facilitate taking food materials from the frying barrel 20 and placing food materials into the frying barrel 20. In addition, hot air enters the frying barrel 20 from the open end of the frying barrel 20, so that the food materials in the frying barrel 20 can be evenly cooked.

[0045] As shown in Figure 3 , the cooking appliance can comprise a fan assembly 30. The fan assembly 30 is arranged in the containing space, and the fan assembly 30 comprises a motor 303, a hot air fan 301 and a cooling fan 302.

[0046] In some embodiments, as shown in Figure 3 , the hot air fan 301 is connected with the rotating shaft 3037 of the motor 303.

[0047] In some embodiments, in the vertical direction, as shown in Figure 3As shown, the cross-sectional area of the heat dissipation fan 302 covers at least part of the cross-sectional area of the motor 303. That is, the heat dissipation fan 302 and the motor 303 at least partially overlap in the height direction of the cooking appliance, so that the height of the fan assembly 30 is reduced.

[0048] In some embodiments, at least part of the heat dissipation fan 302 is arranged on the side of the motor 303, so that the heat dissipation fan 302 and the motor 303 are not arranged in a stacked manner in the height direction, thereby reducing the overall height of the fan assembly 30.

[0049] In the related art, the heat dissipation fan is usually arranged below the motor, which undoubtedly occupies the height space of the cooking appliance. However, the height of the fan assembly of the cooking appliance according to the embodiments of the present application is reduced, so that the overall height of the cooking appliance is reduced.

[0050] In a possible implementation manner, as shown in Figures 4 to 6 The motor 303 includes a stator 3035 and a rotor 3036 arranged outside the stator 3035. The rotor 3036 is arranged on the outer periphery of the heat dissipation fan 302, and the shaft 3037 is connected to the hot air fan 301, so that the heat dissipation fan 302 at least partially overlaps the motor 303 in the height direction, thereby reducing the overall height of the fan assembly 30.

[0051] In some embodiments, as shown in Figures 4 to 6 The heat dissipation fan 302 is fixedly connected to the motor 303, and the heat dissipation fan 302 is provided with flow guide ribs 3032 arranged at intervals, and a cold air outlet 3033 is formed between each two adjacent flow guide ribs 3032. It can be understood that the motor 303 can drive the heat dissipation fan 302 and the hot air fan 301 to rotate at the same time. Through one motor 303, the flow of cold air for heat dissipation can be accelerated, and the circulation efficiency of hot air for cooking can be improved. The number of structural parts of the cooking appliance is simplified, the space is saved, and the cost is reduced.

[0052] The cooking appliance can include a heating element 70. The heating element 70 is located between the open end of the frying barrel 20 and the fan assembly 30, and can generate high-temperature heat energy. The fluid disturbed by the hot air fan 301 in the fan assembly 30 passes through the heating element 70 and enters the cooking space of the frying barrel 20, and forms a circulation in the cooking space to fry the food material, thereby obtaining healthier low-oil-content food.

[0053] Therefore, the cooking appliance provided by the embodiments of the present application reduces the height of the fan assembly 30 by arranging the cross-sectional area of the heat dissipation fan 302 to cover at least part of the cross-sectional area of the motor 303 in the vertical direction, thereby realizing the compact design of the cooking appliance in the height direction, and ensuring that the cooking appliance can be further miniaturized to meet the use requirements of small-sized kitchens.

[0054] In some embodiments, as shown in Figure 3 The housing 10 includes an outer shell 101 and a cooking bin 102. The cooking bin 102 can be understood as an inner shell located in the outer shell 101. The outer shell 101 forms the above-mentioned accommodation space, and the cooking bin 102 is arranged inside the outer shell 101, and a fluid channel 80 is formed between the outer shell 101 and the cooking bin 102, which is in communication with the outside.

[0055] The outer shell 101 is an appearance part of the cooking appliance. The cooking bin 102 is arranged inside the outer shell 101, and the cooking bin 102 is used to enclose a space for accommodating the frying barrel 20, and the frying barrel 20 can be separated from the cooking bin 102.

[0056] In some embodiments, as shown in Figure 3 and Figure 7 The cooking appliance further includes a reflector cover 50. The reflector cover 50 is arranged above the frying barrel 20. The reflector cover 50, the cooking bin 102 and the outer shell 101 form the fluid channel 80 and are in communication with the outside, so as to achieve the purpose of heat dissipation.

[0057] Specifically, the reflector cover 50 can also be indirectly connected to the cooking bin 102. The side space between the cooking bin 102 and the outer shell 101 is in communication with the top space between the reflector cover 50 and the outer shell 101, and forms the fluid channel 80 in communication with the outside.

[0058] As shown in Figure 3 and Figure 7 The inner side of the reflector cover 50 refers to the side of the reflector cover 50 close to the lower pot body 22, and the outer side of the reflector cover 50 refers to the side of the reflector cover 50 away from the lower pot body 22. The heating element 70 and the hot air fan 301 are located on the inner side of the reflector cover 50, and the heating element 70 is located on the side of the hot air fan 301. The heat dissipation fan 302 and the motor 303 are located on the outer side of the reflector cover 50.

[0059] It can be understood that the cooking bin 102 encloses the outside of the frying barrel 20. Since the hot air circulates in the frying barrel 20, the frying barrel 20 radiates a large amount of heat to the surrounding environment. By arranging the fluid channel 80 on the periphery of the frying barrel 20, the heat of the periphery of the frying barrel 20 can be dissipated as soon as possible, thereby avoiding the radiation of these heat to the outer shell 101 and causing the temperature of the outer shell 101 to be too high. In addition, the fluid channel 80 located on the periphery of the frying barrel 20 also helps to keep the temperature of the cooking space inside the frying barrel 20 within the set range.

[0060] The side of the reflecting cover 50 facing away from the hot air cavity is located in the fluid channel 80. Since the heating element 70 generates high-temperature heat energy when in operation, after the heating element 70 is operated for a long time, the heat energy is radiated to the outer shell 101, thereby causing the outer shell 101 to deform and causing the risk of scalding the user. Therefore, the top space between the reflecting cover 50 and the outer shell 101 forms the fluid channel 80, and the hot air radiated by the heating element 70 to the periphery can be taken out of the cooking appliance, thereby improving the use safety of the cooking appliance.

[0061] In some embodiments, as shown in Figure 3 and Figure 7 The reflecting cover 50 is configured as a cover structure to form a hot air cavity accommodating the hot air fan 301 and the heating element 70, and the hot air cavity is communicated with the cooking space of the frying bucket 20.

[0062] In some embodiments, as shown in Figure 3 and Figure 7 The cooking appliance further comprises a heat insulation cover 40. The heat insulation cover 40 is arranged in the fluid channel 80, and the reflecting cover 50 and the heat insulation cover 40 form a cold air cavity 304. The cold air cavity 304 can be part of the fluid channel 80.

[0063] In some embodiments, the side of the heat insulation cover 40 facing away from the cold air cavity 304 is used to fix the circuit device 120.

[0064] Specifically, the circuit device 120 can include a circuit board and electronic components (processors, temperature detection devices, etc.) arranged on the circuit board.

[0065] Since the heat insulation cover 40 forms the cold air cavity 304, the temperature of the heat insulation cover 40 is within a controllable temperature range. Arranging the circuit components on the side of the heat insulation cover 40 facing away from the cold air cavity 304 can ensure that the circuit components are also in a controllable temperature environment, thereby ensuring the working stability and service life of the circuit components.

[0066] In some embodiments, as shown in Figure 8 The shell 10 can be provided with an air outlet 60, and the air outlet 60 is communicated with the fluid channel 80 to realize the communication between the fluid channel 80 and the outside.

[0067] In some embodiments, as shown in Figures 4 to 6 The fan assembly 30 further comprises a fixing frame 3031 for fixing the fan assembly 30 on the heat insulation cover 40, that is, the heat insulation cover 40 provides structural support for the fan assembly 30.

[0068] In some embodiments, the heat insulation cover 40 can be arranged on the top of the cooking bin 102, and the reflecting cover 50 is arranged on the heat insulation cover 40. In this way, the heat insulation cover 40 can support the fan assembly 30 and the reflecting cover 50.

[0069] In some embodiments, the heat dissipation fan 302 and the motor 303 are arranged in the cold air cavity 304. The cold air cavity 304 can also dissipate heat for the motor 303.

[0070] The heat dissipation fan 302 and the motor 303 are arranged in the cold air cavity 304, and when the motor 303 works, the heat dissipation fan 302 is driven to rotate, which can accelerate the fluid flow speed in the cold air cavity 304, thereby accelerating the exchange speed of cold and hot air and improving the heat dissipation efficiency. After the cold air flowing from the outside exchanges heat in the fluid channel 80, it is discharged from the air outlet 60 of the cooking utensil, thereby ensuring the use safety of the cooking utensil.

[0071] In order to avoid that the air after heat exchange blows to the user, the air outlet 60 can be arranged at the back of the cooking utensil.

[0072] In some embodiments, as shown in Figure 2 and Figure 3 The cooking utensil further includes a partition plate 130. The partition plate 130 divides the outer shell 101 into a first outer shell 1011 and a second outer shell 1012 arranged in a vertical direction. The first outer shell 1011 and the partition plate 130 form an upper cavity, and the second outer shell 1012 and the partition plate 130 form a lower cavity.

[0073] It should be noted that the above-mentioned fryer buckets 20, fan assemblies 30, heat shields 40, and reflectors 50 are configured as two and are respectively located in the upper cavity and the lower cavity.

[0074] Among them, the fryer bucket 20, the fan assembly 30, the heat shield 40, and the reflector 50 located in the upper cavity can be respectively an upper pot body 21, a first fan assembly, a first heat shield, and a first reflector. The fryer bucket 20, the fan assembly 30, the heat shield 40, and the reflector 50 located in the lower cavity can be respectively a lower pot body 22, a second fan assembly, a second heat shield, and a second reflector.

[0075] As shown in Figure 2 and Figure 3 The cooking utensil can include a partition plate 130 connected to the first outer shell 1011 and the second outer shell 1012 and located between the first outer shell 1011 and the second outer shell 1012.

[0076] The partition plate 130 has heat insulation performance and can be made of high-temperature-resistant and heat-insulating materials, such as thermosetting heat-insulating materials, to ensure that the partition plate 130 has heat insulation performance in a high-temperature cooking environment. In this way, the partition plate 130 can reduce heat transfer between the upper pot body 21 and the lower pot body 22, so that the food materials cooked in the upper pot body 21 and the lower pot body 22 can obtain the expected cooking effect.

[0077] In some embodiments, the fluid channel 80 is formed in each accommodation space. For the sake of distinction, the fluid channel 80 in the upper cavity is referred to as the first fluid channel 801. The fluid channel 80 in the lower cavity is referred to as the second fluid channel 802.

[0078] Further, as shown in Figure 8 The air outlet 60 includes a first air outlet 601 and a second air outlet 602. The first air outlet 601 is arranged in the first shell 1011, and the second air outlet 602 is arranged in the second shell 1012.

[0079] The first air outlet 601 is in communication with the first fluid channel 801, and the second air outlet 602 is in communication with the second fluid channel 802.

[0080] In some embodiments, the first fluid channel 801 and the second fluid channel 802 are independent of each other, that is, the airflow in the first fluid channel 801 and the second fluid channel 802 does not flow. The first fluid channel 801 and the second fluid channel 802 are isolated from each other, which can prevent the airflow in the upper cavity from mixing with the airflow in the lower cavity and causing the food materials to mix during cooking.

[0081] In some embodiments, the frying barrel 20 includes an upper pot 21 in the upper cavity and a lower pot 22 in the lower cavity. The upper pot 21 is separable from the first shell 1011, and the lower pot 22 is separable from the second shell 1012.

[0082] It is worth noting that the cooking appliance is configured with the upper pot 21 and the lower pot 22, which can be more suitable for the scenario of cooking multiple food materials at the same time. Different types of food materials can be placed in the upper pot 21 and the lower pot 22, respectively, and cooked in the relatively independent upper cavity and lower cavity. Different types of food materials will not mix and stick together, so that the user can cook different food materials at the same time, enriching the use scenarios of the cooking appliance.

[0083] In some embodiments, the shell 101 includes a first shell 1011 and a second shell 1012. The first shell 1011 is located above the second shell 1012.

[0084] In some embodiments, the cooking bin 102 includes an upper cooking bin 1021 and a lower cooking bin 1022. The upper cooking bin 1021 is arranged in the upper cavity and located inside the first shell 1011. The lower cooking bin 1022 is arranged in the lower cavity and located inside the second shell 1012.

[0085] In some embodiments, the upper cooking bin 1021 is used to accommodate the upper pot 21. The second shell 1012 is used to accommodate the lower pot 22.

[0086] The first fluid passage 801 is formed between the first outer shell 1011 and the upper cooking cavity 1021 and the first reflector 501. The upper cooking cavity 21 radiates high heat energy to the outside due to the hot air circulating in the upper cooking cavity 21.

[0087] The first fluid passage 801 is arranged on the outer side and the top of the upper cooking cavity 21. Cold air can be injected into the first fluid passage 801, so that the hot air radiated by the upper cooking cavity 21 can be quickly taken out of the cooking appliance through the first fluid passage 801, preventing the first outer shell 1011 from being heated to a high temperature under the high heat radiation, and reducing the risk of scalding for the user.

[0088] The second fluid passage 802 is formed between the second outer shell 1012 and the lower cooking cavity 1022 and the second reflector 502. The lower cooking cavity 22 radiates high heat energy to the outside due to the hot air circulating in the lower cooking cavity 22.

[0089] The second fluid passage 802 is arranged on the outer side and the top of the lower cooking cavity 22. Cold air can be injected into the second fluid passage 802, so that the hot air radiated by the lower cooking cavity 22 can be quickly taken out of the cooking appliance through the second fluid passage 802, preventing the second outer shell 1012 from being heated to a high temperature under the high heat radiation, and reducing the risk of scalding for the user.

[0090] In some embodiments, the cooking appliance further comprises a top cover 90 connected to the first outer shell 1011, and the first outer shell 1011, the top cover 90 and the partition plate 130 form an upper cavity.

[0091] In some embodiments, as shown in the drawings, the cooking appliance further comprises a first air inlet 901. The first air inlet 901 is arranged on the top cover 90 and located at the connection between the first outer shell 1011 and the top cover 90. The first air inlet 901 is in communication with the first fluid passage 801.

[0092] The top cover 90 is connected to the top of the first outer shell 1011, and the first air inlet 901 in communication with the first fluid passage 801 is arranged on the top cover 90. The first air inlet 901 arranged on the top cover 90 provides a cold air inlet path for the first fluid passage 801, and the heat energy in the first fluid passage 801 can be quickly dissipated, improving the heat dissipation efficiency of the upper cavity.

[0093] The top cover 90 comprises a cover body and a decorative ring. The cover body can be an appearance piece, and the cover body is located at the top of the entire cooking appliance. The inner side of the cover body, i.e., the side facing the upper cavity, is provided with a decorative ring connected with the first shell 1011, and the decorative ring is configured in a ring shape to improve the connection stability between the first shell 1011 and the decorative ring.

[0094] As shown in FIG. 1, the cold air entering the second fluid passage 802 from the second air inlet 100a flows from bottom to top under the disturbance of the cooling fan 302 located in the lower cavity, and then enters the cold air cavity 304 to pass through the cooling fan 302 and then be discharged from the second fluid passage 802. Figure 7

[0095] In some embodiments, as shown in FIG. 1, the cooking appliance further comprises a heat radiation piece 110. The heat radiation piece 110 is arranged at the bottom of the lower cooking chamber body 1022. The heat radiation piece 110 is arranged in the height direction apart from the heating piece 70, and the lower pot body 22 is located between the heating piece 70 and the heat radiation piece 110 in the lower cavity. Figure 7

[0096] Optionally, the heat radiation piece 110 can be a heating pipe, an infrared heating piece 70, a ceramic heating piece 70, etc.

[0097] The arrangement of the heat radiation piece 110 not only improves the heating speed of the food, but also ensures the uniformity of the heating of the food. Since the heat radiation piece 110 is arranged in the height direction apart from the heating piece, the food can be subjected to the action of hot air and heat radiation at the same time during the cooking process. The heat radiation piece 110 radiates heat energy upward from the bottom, and the hot air blown by the hot air fan 301 from the top forms a full-range heating effect on the food. The food can be subjected to the efficient circulation of hot air and the direct penetration of heat radiation at the same time during the cooking process, which can not only ensure that the surface of the food forms a crispy taste, but also further avoid the phenomenon that the bottom of the food is not fully cooked.
