"Multiple" means two or more than two unless otherwise specified.

[0021] See Fig. 1 to 8. One embodiment of the present application provides a cooking appliance. The cooking appliance comprises a housing 10. Within the housing 10, a receiving space is formed, which is used to accommodate a frying basket 20 or other operating devices. The housing 10 also serves to structurally support the frying basket 20 or the other operating devices.

[0022] The housing 10 may be made of a heat-resistant material to ensure the safety of use of the cooking appliance.

[0023] As in Fig. 2 and Fig. As shown in Figure 3, the cooking appliance may include a frying basket 20. The frying basket 20 is removably arranged in the receiving space of the housing 10. A cooking chamber is formed in the frying basket 20, which serves to hold food.

[0024] The fryer basket 20 is structurally open to facilitate the removal of food from the fryer basket 20 and the insertion of food into the fryer basket 20. Furthermore, hot air enters the fryer basket 20 from an open end of the fryer basket 20 to achieve a uniform cooking effect for the food within the fryer basket 20.

[0025] As in Fig. As shown in Figure 3, the cooking appliance may include a fan assembly 30. The fan assembly 30 is arranged in the receiving space. The fan assembly 30 includes a motor 303, a heating fan 301, and a cooling fan 302.

[0026] As in Fig. 3, in some embodiments, the heater fan 301 is connected to a rotating shaft 3037 of the motor 303.

[0027] As in Fig. As shown in Figure 3, in some embodiments, the cross-sectional area of the cooling fan 302 covers at least a portion of the cross-sectional area of the motor 303 in a vertical direction. This means that, in a vertical direction of the cooking appliance, the cooling fan 302 and the motor 303 at least partially overlap, so that the height of the fan assembly 30 is reduced.

[0028] In some embodiments, the cooling fan 302 is arranged at least partially on the circumference of the motor 303 so that a stacked arrangement of the cooling fan 302 and the motor 303 in the height direction can be avoided to reduce the overall height of the fan assembly 30.

[0029] In a prior art cooking appliance, the cooling fan is typically located below the motor, which undoubtedly takes up more space in the height of the cooking appliance. By reducing the height of the fan assembly in the cooking appliance according to an embodiment of the present application, the overall height of the cooking appliance is also reduced.

[0030] As in Fig. As shown in Figures 4 to 6, in one possible implementation, the motor 303 includes a stator 3035 and a rotor 3036 arranged outside the stator 3035. The cooling fan 302 is arranged on the outer circumference of the rotor 3036, and the rotating shaft 3037 is connected to the heating fan 301, so that the cooling fan 302 and the motor 303 can at least partially overlap in the height direction, thus reducing the overall height of the fan assembly 30.

[0031] As in Fig. As shown in Figures 4 to 6, in some embodiments, the cooling fan 302 is fixedly connected to the motor 303. The cooling fan 302 is provided with spaced-apart current-conducting fins 3032. A cold air opening 3033 is formed between each two adjacent current-conducting fins 3032. It should be understood that the motor 303 can simultaneously rotate the cooling fan 302 and the heating fan 301. The single motor 303 not only accelerates the flow of cold air for cooling, but also increases the circulation efficiency of the hot air of the cooking appliance. This reduces the number of components of the cooking appliance, saves space, and reduces costs.

[0032] The cooking appliance may include a heating element 70. The heating element 70 is located between the open end of the frying basket 20 and the fan assembly 30 so that high-temperature heat energy can be generated. The fluid swirled by the heating fan 301 of the fan assembly 30 enters the cooking chamber of the frying basket 20 through the heating element 70 and creates circulation within the cooking chamber to fry the food, resulting in healthier, lower-oil foods.

[0033] Thus, in the cooking appliance according to one embodiment of the present application, a sectional surface of the cooling fan 302 covers at least part of a sectional surface of the motor 303 in the vertical direction, reducing the height of the fan assembly 30 and thus achieving a compact design of the cooking appliance in a vertical direction. This ensures that the cooking appliance can be further downsized to meet the usage needs of a small kitchen.

[0034] As in Fig. As shown in Figure 3, in some embodiments, the housing 10 comprises an outer shell 101 and a cooking container 102. The cooking container 102 can be understood as an inner shell within the outer shell 101. The outer shell 101 forms the above-mentioned receiving space. The cooking container 102 is arranged within the outer shell 101. A fluid channel 80, which is in communication with the environment, is formed between the outer shell 101 and the cooking container 102.

[0035] The outer shell 101 is an aesthetic element of the cooking appliance. The cooking container 102 is arranged within the outer shell 101. The cooking container 102 encloses a space for accommodating the frying basket 20. The frying basket 20 is detachably located within the cooking container 102.

[0036] As in Fig. 3 and Fig. As shown in Figure 7, in some embodiments, the cooking appliance further includes a reflector 50. The reflector 50 is located above the frying basket 20. A fluid channel 80 is formed between the reflector 50, the cooking container 102, and the outer shell 101, which fluid channel communicates with the environment to achieve cooling.

[0037] Specifically, the reflector 50 may also be indirectly connected to the cooking container 102. A lateral space between the cooking container 102 and the outer shell 101 communicates with an upper space between the reflector 50 and the outer shell 101, and the fluid channel 80, which communicates with the environment, is formed.

[0038] As in Fig. 3 and Fig. 7, an inner side of the reflector 50 refers to a side of the reflector 50 facing the lower pot 22, and an outer side of the reflector 50 refers to a side of the reflector 50 facing away from the lower pot 22. The heating element 70 and the heating fan 301 are located on the inner side of the reflector 50, and the heating element 70 is located on one side of the heating fan 301 and the reflector 50, respectively. The cooling fan 302 and the motor 303 are located on the outer side of the reflector 50.

[0039] It should be understood that the cooking container 102 is arranged around the outside of the frying basket 20. As the hot air circulates within the frying basket 20, a large amount of heat is radiated from the frying basket 20 to the surroundings. By disposing the fluid channel 80 on the outer periphery of the frying basket 20, the heat on the outer periphery of the frying basket 20 can be dissipated as quickly as possible, preventing the heat radiation from radiating to the outer shell 101 and causing the outer shell 101 to become too hot. Furthermore, the fluid channel 80 on the periphery of the frying basket 20 also helps maintain the temperature of the cooking chamber within the frying basket 20 within a set range.

[0040] A side of the reflector 50 facing away from the hot air chamber is located in the fluid channel 80. Because the heating element 70 can generate high-temperature heat energy during operation, this heat energy is radiated to the outer shell 101 after prolonged operation of the heating element 70, posing a risk such as deformation of the outer shell 101 or burns to the user. Therefore, the fluid channel 80 is formed in an upper space between the reflector 50 and the outer shell 101, allowing the hot air radiated to the outer periphery by the heating element 70 to be discharged from the cooking appliance, thus increasing the safety of use of the cooking appliance.

[0041] As in Fig. 3 and Fig. 7, in some embodiments, the reflector 50 is configured as a cover structure to form a hot air chamber for receiving the heating fan 301 and the heating element 70, wherein the hot air chamber is in communication with the cooking chamber of the frying basket 20.

[0042] As in Fig. 3 and Fig. As shown in Figure 7, in some embodiments, the cooking appliance further includes a heat-insulating cover 40. The heat-insulating cover 40 is arranged in the fluid channel 80. A cold air chamber 304 is formed between the reflector 50 and the heat-insulating cover 40. The cold air chamber 304 may constitute a portion of the fluid channel 80.

[0043] In some embodiments, it is provided that a side of the thermal insulation cover 40 facing away from the cold air chamber 304 serves for fastening a circuit device 120.

[0044] In particular, the circuit device 120 may include a circuit board and electronic components (a processor, a temperature sensing device, etc.) on the circuit board.

[0045] By forming the cold air chamber 304 using the thermal insulation cover 40, the temperature of the thermal insulation cover 40 is within a controllable temperature range. By arranging a circuit element on a side of the thermal insulation cover 40 facing away from the cold air chamber 304, it can be ensured that the circuit element is also located in a controllable temperature environment, thus ensuring the operational stability and service life of the circuit element.

[0046] As in Fig. As shown in Figure 8, in some embodiments, the housing 10 is provided with an air outlet 60. The air outlet 60 is in communication with the fluid channel 80 to establish communication of the fluid channel 80 with the environment.

[0047] As in Fig. 4 to 6, in some embodiments, the fan assembly 30 further includes a mounting bracket 3031. The mounting bracket 3031 serves to attach the fan assembly 30 to the thermal insulation cover 40. That is, the thermal insulation cover 40 provides structural support for the fan assembly 30.

[0048] In some embodiments, the thermal insulation cover 40 is arranged on top of the cooking container 102, and the reflector 50 is arranged on the thermal insulation cover 40. Thus, the thermal insulation cover 40 can support both the fan assembly 30 and the reflector 50.

[0049] In some embodiments, the cooling fan 302 and the motor 303 are arranged in the cold air chamber 304. The cold air chamber 304 can also provide cooling for the motor 303.

[0050] The cooling fan 302 and the motor 303 are arranged in the cold air chamber 304. When the motor 303 rotates the cooling fan 302 during operation, the flow rate of the fluid in the cold air chamber 304 can be accelerated, thus accelerating the exchange of cold air and hot air and thus increasing the cooling efficiency. After the cold air flowing in from the outside undergoes heat exchange in the fluid channel 80, it is discharged from the cooking appliance through the air outlet 60 to ensure the safe use of the cooking appliance.

[0051] In order to prevent the air from being blown to the user after the heat exchange, the air outlet 60 may be formed on a rear side of the cooking appliance.

[0052] As in Fig. 2 and Fig. 3, in some embodiments, the cooking appliance further comprises a partition plate 130. The partition plate 130 separates the outer shell 101 into a first outer shell 1011 and a second outer shell 1012 in the vertical direction. The first outer shell 1011 and the partition plate 130 form an upper chamber, and the second outer shell 1012 and the partition plate 130 form a lower chamber.

[0053] It should be noted that two of the above frying baskets 20, fan assemblies 30, heat insulating covers 40 and reflectors 50 may be provided, each located in the upper chamber and the lower chamber.

[0054] The frying basket 20, the fan assembly 30, the heat-insulating cover 40, and the reflector 50 in the upper chamber can each be the upper pot 21, the first fan assembly, the first heat-insulating cover, and the first reflector, respectively. The frying basket 20, the fan assembly 30, the heat-insulating cover 40, and the reflector 50 in the lower chamber can each be the lower pot 22, the second fan assembly, the second heat-insulating cover, and the second reflector, respectively.

[0055] As in Fig. 2 and Fig. As shown in Figure 3, the cooking appliance may include a partition plate 130. The partition plate 130 is connected to the first outer shell 1011 and the second outer shell 1012 and is located between the first outer shell 1011 and the second outer shell 1012.

[0056] The partition plate 130 has a heat-insulating property and can be made of a high-temperature-resistant heat-insulating material, such as a heat-insulating thermosetting material, to ensure that the partition plate 130 has a heat-insulating property in a high-temperature cooking environment. Therefore, the partition plate 130 can reduce heat transfer between the upper pot 21 and the lower pot 22, so that the food cooked in the upper pot 21 and the lower pot 22 achieves the desired cooking effect.

[0057] In some embodiments, the above-mentioned fluid channel 80 is formed in each receiving space. For ease of differentiation, the fluid channel 80 in the upper chamber is referred to as a first fluid channel 801 in the embodiment of the present application. The above-mentioned fluid channel 80 is also formed in the lower chamber. In the embodiment of the present application, the fluid channel 80 in the lower chamber is referred to as a second fluid channel 802.

[0058] It is also envisaged that, as in Fig. 8, the air outlet 60 comprises a first air outlet 601 and a second air outlet 602, wherein the first air outlet 601 is provided on the first outer shell 1011 and the second air outlet 602 is provided on the second outer shell 1012. 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.

[0059] In some embodiments, the first fluid channel 801 and the second fluid channel 802 are independent of each other. This means that the airflows in the first fluid channel 801 and the second fluid channel 802 are not in communication with each other. The first fluid channel 801 and the second fluid channel 802 are isolated from each other. This prevents the airflow in the upper chamber from mixing with the airflow in the lower chamber, which results in the odors of the food being mixed during the cooking process.

[0060] In some embodiments, the frying basket 20 includes an upper pot 21 in the upper chamber and a lower pot 22 in the lower chamber. The upper pot 21 may be arranged separately from the first outer shell 1011, and the lower pot 22 may be arranged separately from the second outer shell 1012.

[0061] It should be noted that providing the cooking appliance with the upper pot 21 and the lower pot 22 makes it possible to better adapt to cooking scenarios in which different foods are cooked at once. Thus, different foods can be placed in the upper pot 21 and the lower pot 22, respectively, and cooking takes place in the upper and lower chambers, which are relatively independent of each other, and different foods are neither exposed to mixed odors nor sticking to each other. This allows the user to cook different foods simultaneously, thus enriching the application scenarios of the cooking appliance.

[0062] In some embodiments, the outer shell 101 comprises a first outer shell 1011 and a second outer shell 1012. The first outer shell 1011 is located above the second outer shell 1012.

[0063] In some embodiments, the cooking container 102 comprises an upper cooking container 1021 and a lower cooking container 1022. The upper cooking container 1021 is arranged in the upper chamber and is located within the first outer shell 1011. The lower cooking container 1022 is arranged in the lower chamber and is located within the second outer shell 1012.

[0064] In some embodiments, the upper cooking container 1021 is used to hold the upper pot 21. The second outer shell 1012 is used to hold the lower pot 22.

[0065] The first fluid channel 801 is formed between the first outer shell 1011 and the upper cooking container 1021 and the first reflector 501. Because the hot air cyclically flows in the upper pot 21, the upper pot 21 radiates high heat energy into the outer periphery.

[0066] The first fluid channel 801 is arranged outside and above the upper pot 21, so that cold air can be introduced into the first fluid channel 801. This allows the first fluid channel 801 to discharge the hot air from the cooking appliance through the first fluid channel 801 under the heat radiation of the upper pot 21, preventing the first outer shell 1011 from heating to a higher temperature under the high heat radiation, thus reducing the risk of burns to the user.

[0067] The second fluid channel 802 is formed between the second outer shell 1012 and the lower cooking container 1022 and the second reflector 502. Because the hot air cyclically flows in the lower pot 22, the lower pot 22 radiates high heat energy into the outer periphery.

[0068] The second fluid channel 802 is arranged outside and above the lower pot 22, so that cold air can be introduced into the second fluid channel 802. This allows the second fluid channel 802 to discharge the hot air from the cooking appliance through the second fluid channel 802 under the heat radiation of the lower pot 22, preventing the second outer shell 1012 from heating to a higher temperature under the high heat radiation, thus reducing the risk of burns to the user.

[0069] In some embodiments, the cooking appliance further comprises a lid 90. The lid 90 is connected to the first outer shell 1011. The first outer shell 1011, the lid 90, and the partition plate 130 form the upper chamber.

[0070] As in Fig. As shown in Figure 7, in some embodiments, the cooking appliance further comprises a first air inlet 901. The first air inlet 901 is arranged on the lid 90 and is located at a junction between the first outer shell 1011 and the lid 90. The first air inlet 901 is in communication with the first fluid channel 801.

[0071] The lid 90 is connected to an upper surface of the first outer shell 1011. The lid 90 is provided with the first air inlet 901, which communicates with the first fluid channel 801. The first air inlet 901 on the lid 90 provides an entry path for the cold air to the first fluid channel 801, allowing the thermal energy in the first fluid channel 801 to be quickly dissipated, thus increasing the cooling efficiency of the upper chamber.

[0072] The lid 90 comprises a lid body and a cladding ring. The lid body can be an appearance element and is located on the top of the entire cooking appliance. A cladding ring, which is connected to the first outer shell 1011, is arranged on an inner side of the lid body, i.e., on a side facing the upper chamber. The cladding ring is annular to increase the stability of the connection between the first outer shell 1011 and the cladding ring.

[0073] As in Fig. 7, the cold air entering the second fluid channel 802 through a second air inlet 100a can flow upwards from the bottom of the lower chamber under the swirling action of the cooling fan 302 and then enters the cold air chamber 304 to be subsequently discharged from the second fluid channel 802 through the cooling fan 302.

[0074] As in Fig.As shown in Figure 7, in some embodiments, the cooking appliance further includes a heat emitter 110. The heat emitter 110 is arranged on the underside of the lower cooking container 1022. The heat emitter 110 and the heating element 70 are arranged spaced apart from each other in the vertical direction. The lower pot 22 is located between the heating element 70 and the heat emitter 110 in the lower chamber.

[0075] Optionally, the heat emitter 110 may be a heating tube, an infrared heating element, a ceramic heating element or the like.

[0076] The provision of the heat emitter 110 not only increases the heating speed of the food but also ensures uniform heating of the food. Because the heat emitter 110 and the heating element 70 are arranged vertically spaced from each other, the food can be exposed to the effects of hot air and heat radiation simultaneously during the cooking process. The heat emitter 110 radiates heat energy from the bottom upward, and the heating fan 301 blows hot air from the top, thus creating a full-surface heating effect on the food. During the cooking process, the food can be exposed to efficient circulation of hot air and direct penetration of heat radiation simultaneously, thus not only ensuring a crispy taste on the surface of the food but also preventing the phenomenon of undercooked food on the bottom.
