[0055] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0056] like Figures 1 to 8 As shown, a cooking appliance is proposed according to an embodiment of the present disclosure, comprising: a shell portion 100, wherein the shell portion 100 has a first air duct 101 and a second air duct 102, the first air duct 101 being located on the bottom wall of the shell portion 100; a pot body portion 200 disposed within the shell portion 100, wherein a third air duct 103 is formed between the pot body portion 200 and the shell portion 100, at least a portion of the third air duct 103 surrounding the periphery of the pot body portion 200, and both the first air duct 101 and the second air duct 102 being connected to the third air duct 103; and an air supply portion 300 disposed within the shell portion 100, wherein one of the air inlet end and the air outlet end of the air supply portion 300 is connected to the first air duct 101, and the other is located within the third air duct 103.

[0057] The cooking appliance provided in this embodiment includes a shell portion 100, a pot body portion 200, and an air supply portion 300. The shell portion 100 has a first air duct 101 and a second air duct 102. The first air duct 101 is located on the bottom wall of the shell portion 100. The pot body portion 200 is disposed inside the shell portion 100, and a third air duct 103 is formed between the pot body portion 200 and the shell portion 100, communicating with the first air duct 101 and the second air duct 102. At least a portion of the third air duct 103 is located around the periphery of the pot body portion 200. The air supply portion 300 is disposed in the shell portion 100, and one of its air inlet and air outlet ends is connected to the first air duct 101, while the other is located within the third air duct 103. Based on the aforementioned configuration, the cooking appliance provided in this embodiment can utilize… The aforementioned air ducts provide space for gas flow. In practical applications, after the cooking appliance finishes cooking, the air supply unit 300 provides power for the gas to flow through the aforementioned air ducts. When the gas flows along the aforementioned third air duct 103, it can exchange heat with the pot body 200, improving the heat dissipation efficiency of the pot body 200. It can also enhance the gas flow in the bottom area of ​​the pot body 200, increasing the heat dissipation rate in the bottom area of ​​the pot body 200. This can improve the heat dissipation effect on the heat-concentrated areas of the pot body 200 during the heat dissipation process, accelerate the cooling speed of the pot body 200 and the food inside the pot body 200, save energy consumption when the cooking appliance dissipates and cools the pot body 200, ensure the energy efficiency of the product, and improve the user experience of the product.

[0058] It is understood that, in practical applications, the cooking appliances provided in this disclosure can be used as, but are not limited to, electric cookers, rice cookers, electric pressure cookers, and other cooking equipment; the aforementioned shell portion 100 and the aforementioned pot body portion 200 can both be groove-shaped structures, that is, the shell portion 100 and the pot body portion 200 can both be hollow inside and open at one end. The internal space of the pot body portion 200 can be used as a cooking space, and the internal space of the shell portion 100 can be used as a accommodating space to accommodate the pot body portion 200; the bottom wall of the aforementioned shell portion 100 is also the side opposite to the open end of the shell portion 100, and the peripheral wall of the aforementioned shell portion 100 is also the part between the open end and the bottom wall of the shell portion 100. Similarly, the bottom wall of the pot body portion 200 is also the side opposite to the open end of the pot body portion 200, and the peripheral wall of the pot body portion 200 is also the part between the open end and the bottom wall of the pot body portion 200. The periphery of the pot body portion 200 is also the outer side of the peripheral wall of the pot body portion 200.

[0059] It should be noted that, taking the cooking appliance provided in this embodiment as an example when used as an electric pressure cooker, the cooking appliance can also reduce the internal pressure of the pot body 200 by lowering the temperature of the pot body 200. This helps to reduce the noise generated when the cooking appliance releases pressure, reduce the safety burden on the user during operation, and improve the user experience of the product.

[0060] It is understood that the aforementioned first air duct 101 and second air duct 102 are both connected to the third air duct 103. That is, the first air duct 101 is connected to the second air duct 102 through the third air duct 103. When the air supply unit 300 is running, the air supply unit 300 can drive the gas from the first air duct 101 to the third air duct 103 or drive the gas from the third air duct 103 to the first air duct 101. Thus, one of the aforementioned first air duct 101 and the aforementioned second air duct 102 can serve as the inlet channel for gas from the external environment to flow into the housing 100. Correspondingly, the other can serve as the outlet channel for gas to flow out of the housing 100, which is specifically related to the location of the air inlet and air outlet of the air supply unit 300. For example, when the air inlet of the air supply unit 300 is connected to the first air duct 101 and the air outlet is located in the third air duct 103, the air supply unit 300 can draw in gas from the external environment through the first air duct 101 during operation and deliver it to the aforementioned third air duct 103, so as to use the low-temperature gas in the external environment to accelerate the heat dissipation of the pot body 200. After flowing through the third air duct 103, the gas can further flow to the external environment through the second air duct 102. In this case, the first air duct 101 can serve as the aforementioned inlet channel, and the second air duct 102 can serve as the aforementioned outlet channel; or, the air outlet of the air supply unit 300 is connected to the first air duct 101. 01. When the air inlet is located in the third air duct 103, the air supply unit 300 can draw in the gas in the third air duct 103 and discharge it into the shell part 100 through the first air duct 101 during operation, so as to increase the gas flow rate around the pot part 200 and accelerate the heat dissipation of the pot part 200. Correspondingly, the gas in the external environment can enter the shell part 100 through the second air duct 102 and flow to the third air duct 103 to supplement the third air duct 103 with the lower temperature gas, so as to ensure the heat dissipation efficiency of the pot part 200. In this case, the first air duct 101 can be used as the aforementioned inlet channel and the second air duct 102 can be used as the aforementioned outlet channel.

[0061] It is understood that the cooking appliance provided in this disclosure, by creating a first air duct 101 in the bottom wall of the shell portion 100 and providing at least a portion of a third air duct 103 around the periphery of the pot body portion 200, can, on the one hand, cause the gas in the third air duct 103 to flow around the periphery of the pot body portion 200 when the air supply portion 300 is running, and can increase the distribution range of the air ducts inside the shell portion 100, thereby increasing the contact area between the airflow and the pot body portion 200 and improving the cooling and depressurization efficiency of the pot body portion 200; on the other hand, it can place the first air duct 101 at a relatively low position, thereby based on the first air duct 101 and the third air duct The connection between 103 and the structural positional relationship between the shell part 100 and the pot body part 200 facilitates the extension of the third air duct 103 to the bottom of the pot body part 200. Thus, when the air supply part 300 is running, it can improve the heat dissipation efficiency of the pot body part 200 around the pot body part 200 while improving the heat dissipation at the bottom of the pot body part 200. It is understood that during the cooking process, the bottom of the pot body part 200 is usually heated and the food inside the pot body part 200 usually occupies the bottom space of the pot body part 200 first. Therefore, the heat at the bottom of the pot body part 200 is relatively concentrated. Based on the aforementioned arrangement, it helps to improve the overall heat dissipation efficiency of the pot body part 200.

[0062] It should be noted that the first air duct 101 is provided on the bottom wall of the aforementioned housing portion 100, which means that one end of the first air duct 101 connected to the third air duct 103 is located on the bottom wall of the housing portion 100, and the other end of the first air duct 101 can be located on the bottom wall or the peripheral wall of the housing portion 100.

[0063] It is understood that the cooking appliance provided in this disclosure, by setting one of the air inlet and air outlet of the air supply unit 300 to be connected to the first air duct 101 and the other located in the third air duct 103, can specifically enhance the driving efficiency of the air supply unit 300 on the gas in the third air duct 103. This is beneficial to accelerate the speed of gas flowing around the pot body 200, reduce gas flow resistance, and at the same time facilitate gas exchange between the pot body 200 and the external environment through the first air duct 101, thereby ensuring the heat dissipation effect of the airflow on the pot body 200 and saving the energy consumption of the air supply unit 300.

[0064] like Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, in some examples, the third air duct 103 includes: a first channel section 1031 formed between the bottom wall of the pot body portion 200 and the bottom wall of the shell portion 100; and a second channel section 1032 formed between the peripheral wall of the pot body portion 200 and the peripheral wall of the shell portion 100; wherein, one of the air inlet end and the air outlet end of the air supply portion 300 is connected to the first air duct 101, and the other is located within the first channel section 1031.

[0065] In this technical solution, the aforementioned third air duct 103 may include a first channel section 1031 and a second channel section 1032. The first air duct 101 is connected to the first channel section 1031, and the second air duct 102 is connected to the second channel section 1032. The first channel section 1031 is located between the bottom wall of the pot body 200 and the bottom wall of the shell 100, thus providing space for gas flow between them. Therefore, when the air supply unit 300 is operating, it can improve the heat dissipation efficiency around the pot body 200 while also improving the heat dissipation at the bottom of the pot body 200, thereby contributing to improved overall heat dissipation efficiency of the pot body 200. The first channel section 1031 provides favorable conditions for the rapid depressurization of the cooking appliance after cooking. When a heating device for heating the bottom of the pot body 200 is provided in the first channel section 1031, the airflow in the first channel section 1031 can also dissipate heat from the aforementioned heating device, preventing the pot body 200 from further absorbing a large amount of residual heat from the heating device after cooking. The second channel section 1032 is located between the peripheral wall of the pot body 200 and the peripheral wall of the shell section 100. When the air supply section 300 is running, the gas in the third air duct 103 can form a tendency to flow around the periphery of the pot body 200, which is conducive to increasing the contact area between the airflow and the pot body 200 and improving the cooling and depressurization efficiency of the pot body 200.

[0066] Accordingly, one of the air inlet and air outlet of the air supply unit 300 can be connected to the first air duct 101, and the other can be located within the first channel section 1031. When the air inlet of the air supply unit 300 is connected to the first air duct 101 and the air outlet is located within the first channel section 1031, the air supply unit 300 can deliver low-temperature gas from the external environment into the first channel section 1031 during operation. This allows the low-temperature gas to preferentially act on the bottom area of ​​the pot body 200 where heat distribution is more concentrated, which is beneficial for specifically enhancing the heat dissipation effect of the airflow on the bottom of the pot body 200. Alternatively, when the air outlet of the air supply unit 300 is connected to the first air duct 101 and the air inlet is located within the first channel section 1031, the air supply unit 300 can quickly guide high-temperature gas from the first air duct 101 into the first air duct 101 during operation. This helps shorten the flow path of the high-temperature gas after passing through the air supply unit 300, facilitating the rapid discharge of the high-temperature gas to the external environment and improving the heat dissipation and pressure reduction efficiency of the cooking appliance.

[0067] It is understood that the third air duct 103 is defined by the inner surface of the shell portion 100 and the outer surface of the pot body portion 200. The aforementioned first channel segment 1031 and the aforementioned second channel segment 1032 can be distinguished by the bottom wall of the pot body portion 200. The first channel segment 1031 is defined by the inner side of the bottom wall of the shell portion 100, the outer side of the bottom wall of the pot body portion 200, and the inner side of the peripheral wall of the shell portion 100 located between the inner side of the bottom wall of the shell portion 100 and the outer side of the bottom wall of the pot body portion 200. Thus, in practical applications, the shape of the third air duct 103 is constrained by the shape of the shell portion 100 and the pot body portion 200.

[0068] like Figure 1 , Figure 3 , Figure 5 , Figures 6 to 8 As shown, in some examples, the air supply unit 300 includes: a drive assembly 310 disposed in the housing portion 100; a centrifugal impeller 320 connected to the drive assembly 310, at least a portion of the centrifugal impeller 320 being located within the first channel section 1031; wherein the peripheral side of the centrifugal impeller 320 faces the peripheral wall of the housing portion 100, and one axial end of the centrifugal impeller 320 faces the first air duct 101.

[0069] In this technical solution, the aforementioned air supply unit 300 may include a drive assembly 310 and a centrifugal impeller 320 connected to each other. The drive assembly 310 is disposed in the housing 100, so the housing 100 can provide structural support for the drive assembly 310 and ensure the stability of the drive assembly 310. At least a portion of the centrifugal impeller 320 is located in the aforementioned first channel section 1031, and the periphery of the centrifugal impeller 320 faces the peripheral wall of the housing 100. One axial end of the centrifugal impeller 320 faces the end of the first air duct 101 connected to the first channel section 1031. Thus, when the centrifugal impeller 320 rotates under the drive of the drive assembly 310, it can guide the gas in the first channel section 1031 to the first air duct 101 or guide the gas in the first air duct 101 to the first channel section 1031, thereby causing the gas in the third air duct 103 to flow, thereby improving the cooling and depressurization efficiency of the pot body 200.

[0070] It is understood that the air inlet and outlet of the aforementioned air supply section 300 are formed in the aforementioned centrifugal impeller 320, and one of the radial and axial directions of the centrifugal impeller 320 can be used as the air inlet direction and the other as the air outlet direction. Given a fixed rotation direction and structure of the centrifugal impeller 320, the specific air inlet and outlet directions are related to the arrangement of the centrifugal impeller 320. Therefore, when the periphery of the centrifugal impeller 320 faces the peripheral wall of the housing section 100, based on the arrangement positions of the aforementioned first channel section 1031 and second channel section 1032, the centrifugal impeller... The radial direction of 320 can point to the second channel section 1032 located between the peripheral wall of the pot body 200 and the peripheral wall of the shell 100, and maintain good consistency with the extension direction of the first channel section 1031. Thus, whether the centrifugal impeller 320 is circumferentially inlet or outlet, the airflow can pass through the aforementioned first channel section 1031 more quickly, which helps to reduce the resistance during gas flow and further improve the heat dissipation efficiency of the gas to the pot body 200. When the cooking appliance is used as an electric pressure cooker, it is beneficial to achieve rapid pressure reduction inside the pot body 200.

[0071] For example, such as Figure 7 As shown, Figure 7 The diagram schematically illustrates the configuration of the centrifugal impeller 320 with axial air intake and circumferential air exhaust. Correspondingly, in this configuration, the airflow can rapidly flow through the first channel section 1031 to the bottom of the second channel section 1032 after exiting the centrifugal impeller 320; as... Figure 8 As shown, Figure 8 The schematic diagram shows the configuration of the centrifugal impeller 320 with axial and circumferential air intake. Accordingly, in this case, the gas located around the centrifugal impeller 320 in the first channel section 1031 can quickly flow through the centrifugal impeller 320 to the first air duct 101 when the centrifugal impeller 320 rotates. Correspondingly, the gas in the second channel section 1032 can also quickly flow into the bottom first channel section 1031.

[0072] like Figure 7 and Figure 8 As shown, in some examples, the cross-sectional area of ​​the second channel segment 1032 increases along the direction from the bottom wall of the shell portion 100 to the bottom wall of the pot body portion 200.

[0073] It is understood that the cross-sectional area of ​​the aforementioned first channel segment 1031 refers to the cross-sectional area of ​​the first channel segment 1031 in the direction perpendicular to the bottom wall of the shell portion 100 to the bottom wall of the pot body portion 200. Furthermore, based on the aforementioned arrangement of the first channel segment 1031 and the second channel segment 1032, the overall height of the first channel segment 1031 is lower than the height of the second channel segment 1032. Based on this arrangement, the guiding effect of the second channel segment 1032 can be improved, thereby allowing airflow from the first channel segment 1031 to the second channel segment 1032. When the airflow is flowing, the gas can rise more rapidly and diffuse into the second channel section 1032 surrounding the pot body 200. Alternatively, when the airflow flows from the second channel section 1032 to the first channel section 1031, the airflow in the second channel section 1032 can rapidly descend and concentrate into the first channel section 1031. This can further reduce the flow resistance of the gas in the third air duct 103, reduce the energy loss of the gas during the flow process, improve the heat dissipation efficiency of the gas on the pot body 200, and facilitate the rapid depressurization of the pot body 200.

[0074] like Figures 1 to 5 , Figure 7 and Figure 8 As shown, in some examples, the housing 100 includes: a first housing 110, which has a groove-shaped structure; a first air duct 101 including a first ventilation hole 1011 opened in the first housing 110; and a second air duct 102 including a second ventilation hole 1021 opened in the first housing 110; a second housing 120 disposed within the first housing 110, which also has a groove-shaped structure; the first air duct 101 further including a third ventilation hole 1013 opened in the bottom wall of the second housing 120; and the second air duct 102 further including a fourth ventilation hole 1023 opened in the peripheral wall and / or bottom wall of the second housing 120; wherein, the pot body 200 is disposed within the second housing 120, and the air supply part 300 passes through the third ventilation hole 1013.

[0075] In this technical solution, the aforementioned shell portion 100 may include a first shell 110 and a second shell 120. Both the first shell 110 and the second shell 120 may be groove-shaped structures. Accordingly, the second shell 120 is disposed inside the first shell 110, the aforementioned pot body portion 200 is disposed inside the second shell 120, and the aforementioned third air duct 103 is formed between the second shell 120 and the pot body portion 200. In practical applications, the aforementioned second shell 120 can be used as the outer pot of a cooking utensil, the pot body portion 200 can be used as the inner pot of a cooking utensil, and the first shell 110 can be used as the outer shell of a cooking utensil.

[0076] The first housing 110 has a first ventilation hole 1011 and a second ventilation hole 1021, and the second housing 120 has a third ventilation hole 1013 and a fourth ventilation hole 1023. The aforementioned first air duct 101 includes the aforementioned first ventilation hole 1011 and the aforementioned third ventilation hole 1013, and one end of the first air duct 101 connected to the third air duct 103 is located at the aforementioned third ventilation hole 1013, that is, the third ventilation hole 1013 is opened on the bottom wall of the second housing 120. The aforementioned second air duct 102 includes the aforementioned second ventilation hole 1021 and the aforementioned fourth ventilation hole 1023, and one end of the second air duct 102 connected to the aforementioned third air duct 103 is located at the aforementioned fourth ventilation hole 1023. When the air supply unit 300 is in operation, gas in the external environment can flow into the housing 100 through one of the first ventilation hole 1011 and the second ventilation hole 1021, and flow out of the housing 100 through the other.

[0077] The aforementioned air supply unit 300 can be inserted through the aforementioned third ventilation hole 1013, thereby facilitating that one of the air inlet end and the air outlet end of the air supply unit 300 is located in the third air duct 103, and the other is connected to the first air duct 101, so as to promote the flow of gas in each air duct of the cooking appliance when the air supply unit 300 is running, thereby achieving cooling and pressure reduction of the pot body 200. Based on the aforementioned arrangement, it is beneficial to improve the utilization rate of the internal space of the shell part 100 and enhance the structural compactness and miniaturization level of the cooking appliance.

[0078] It is understood that the aforementioned fourth ventilation hole 1023 can be located on the peripheral wall of the second housing 120, thereby improving the positional matching between the fourth ventilation hole 1023 and the third air duct 103. This facilitates the rapid entry of low-temperature gas from the external environment into the third air duct 103 through the second air duct 102, or facilitates the rapid discharge of high-temperature gas from the third air duct 103 through the second air duct 102, thereby accelerating the gas flow rate and providing further assurance for improving the cooling and depressurization efficiency of the pot body 200; or, the aforementioned fourth ventilation hole 1023 can be located on the peripheral wall of the second housing 120. The bottom wall of the second housing 120 is such that the third ventilation hole 1013 and the fourth ventilation hole 1023 are both located on the bottom wall of the second housing 120, reducing the impact of structural openings on the overall strength of the second housing 120, which is beneficial to extending the service life of the second housing 120 and reducing the risk of damage to the second housing 120; or, the aforementioned fourth ventilation hole 1023 can be partially located on the peripheral wall of the second housing 120 and partially located on the bottom wall of the second housing 120, thereby widening the distribution range of the fourth ventilation hole 1023, improving the efficiency of gas flowing into or out of the third air duct 103, and further improving the heat dissipation efficiency of the pot body.

[0079] It is understood that the first vent 1011 and the third vent 1013 can be directly connected; or, a first gas channel can be formed between the first housing 110 and the second housing 120, connecting the first vent 1011 and the third vent 1013, so that the first vent 1011 and the third vent 1013 are indirectly connected. Correspondingly, the first air duct 101 also includes the aforementioned first gas channel. For example, the aforementioned second gas channel can be, but is not limited to, the installation space between the bottom wall of the first housing 110 and the bottom wall of the second housing 120. The first vent 1011 and the third vent 1013 are connected through the aforementioned installation space. It is understood that the aforementioned installation space can be used to install cooking utensils. Some components, such as the drive assembly 310 of the aforementioned air supply unit 300, the electronic control board, etc.; similarly, the second ventilation hole 1021 and the fourth ventilation hole 1023 can be directly connected, or a second gas channel can be formed between the first housing 110 and the second housing 120, connecting the second ventilation hole 1021 and the fourth ventilation hole 1023, so that the second ventilation hole 1021 and the fourth ventilation hole 1023 are indirectly connected. Correspondingly, the second air duct 102 also includes the aforementioned second gas channel. For example, the aforementioned first gas channel can be, but is not limited to, the circumferential gap between the peripheral wall of the first housing 110 and the peripheral wall of the second housing 120, and the first ventilation hole 1011 and the third ventilation hole 1013 are connected through the aforementioned circumferential gap.

[0080] like Figure 1 As shown, in some examples, the position height H1 of the second ventilation hole 1021 is higher than or equal to the position height H2 of the fourth ventilation hole 1023.

[0081] In this technical solution, the position height H1 of the second ventilation hole 1021 can be set higher than or equal to the position height H2 of the fourth ventilation hole 1023. That is, along the height direction of the housing 100, the second ventilation hole 1021 is opened above the fourth ventilation hole 1023. It can be understood that when the air inlet of the air supply unit 300 is located in the third channel, when the air supply unit 300 is running, the gas will flow from the relatively lower first air duct 101 to the relatively higher second air duct 102. That is, the overall airflow direction is from bottom to top, and the gas will preferentially flow through the fourth ventilation hole 1023, and then flow through the second ventilation hole 1021 to exit the housing 100. The air outlet of the air supply unit 300 is located in the third channel. In this case, when the air supply unit 300 is running, the gas will flow from the relatively high second air duct 102 to the relatively low first air duct 101. That is, the overall airflow direction is from top to bottom, and the gas will preferentially flow through the second ventilation hole 1021, and then through the fourth ventilation hole 1023 to the third air duct 103. Based on the aforementioned arrangement of this technical solution, based on the height difference between the second ventilation hole 1021 and the fourth ventilation hole 1023, a height difference can be formed at both ends of the second air duct 102, and the aforementioned height difference can be adapted to the airflow direction, thereby further reducing the flow resistance of the airflow in the cooking appliance, reducing the airflow loss along the way, and helping to further improve the heat dissipation and pressure reduction efficiency of the gas on the pot body 200.

[0082] It is understandable that the position height H1 of the second ventilation hole 1021 refers to the position height of the lowest position of the second ventilation hole 1021 along the height direction of the housing part 100; similarly, the position height H2 of the fourth ventilation hole 1023 refers to the position height of the lowest position of the fourth ventilation hole 1023 along the height direction of the housing part 100.

[0083] In some examples, the fourth vent 1023 faces the peripheral wall of the pot body 200, and the difference between the height of the fourth vent 1023 and the height of the bottom wall of the pot body 200 is greater than or equal to 1 / 3 of the height of the pot body 200.

[0084] In this technical solution, the difference between the height of the fourth ventilation hole 1023 and the height of the bottom wall of the pot body 200 can be greater than or equal to 1 / 3 of the height of the pot body 200, thereby avoiding the fourth ventilation hole 1023 being too low. It is understood that after cooking, the food in the pot body 200 will have a certain height and high heat, so the heat concentration area of ​​the pot body 200 will also have a certain length along the height direction of the shell part 100. Based on the aforementioned setting of this technical solution, the height of the end of the third air duct 103 connected to the second air duct 102 can be avoided being too low, thereby extending the flow path of the gas in the third air duct 103 along the height direction of the shell part 100, and facilitating the airflow to cover the heat concentration area of ​​the pot body 200. At the same time, it increases the contact area between the airflow and the pot body 200. When there is a lot of food in the pot body 200, it also helps to ensure the heat dissipation effect of the airflow on the pot body 200, thereby ensuring the cooling and pressure relief speed of the pot body 200 after cooking.

[0085] It is understood that the position height of the bottom wall of the aforementioned pot body 200 refers to the position height of the lowest point of the bottom wall of the pot body 200 along the height direction of the shell part 100.

[0086] In some feasible examples, the pot body 200 is detachably disposed within the housing 100, thereby facilitating the cleaning of the pot body 200. It is understood that, in this technical solution, the position height of the bottom wall of the aforementioned pot body 200 refers to the position height of the lowest position of the bottom wall of the pot body 200 along the height direction of the housing 100 when the pot body 200 is disposed within the housing 100.

[0087] like Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, in some examples, a plurality of second air ducts 102 are spaced apart along the circumference of the housing portion 100, and each second air duct 102 includes a plurality of fourth ventilation holes 1023, which are arranged in an array.

[0088] In this technical solution, the cooking appliance can be provided with multiple second air ducts 102, and the multiple second air ducts 102 are arranged at intervals along the circumference of the housing portion 100. Each second air duct 102 includes multiple fourth ventilation holes 1023, and the multiple fourth ventilation holes 1023 are arranged in an array. Based on the aforementioned arrangement, on the one hand, when the air supply unit 300 is running, gas can be allowed to flow through the second air ducts 102 at different circumferential positions, and the second air ducts 102 can easily connect with the third air duct 1 through the fourth ventilation holes 1023 at different circumferential positions. The connection between 03 helps the gas to flow around the pot body 200 in the third air duct 103, thereby ensuring the uniformity of heat dissipation in the pot body 200 and further improving the heat dissipation efficiency of the pot body 200. On the other hand, with a fixed total conduction area of ​​the second air duct 102, the fourth ventilation holes 1023 can be opened in a distributed manner to avoid opening excessively large and continuous holes in the shell part 100, which helps to reduce the weakening of the shell part 100 caused by the opening and ensures the structural reliability of the cooking appliance.

[0089] It is understandable that the array form of the fourth ventilation hole 1023 can be various, such as a ring array, a linear array, a rectangular array, etc. The specific form can be set according to actual needs, and no further restrictions are imposed here.

[0090] In some examples, along the circumference of the housing portion 100, the spacing between two adjacent second air ducts 102 is greater than or equal to the spacing between two adjacent fourth ventilation holes 1023 in each second air duct 102.

[0091] In this technical solution, the spacing between two adjacent second air ducts 102 can be set to be greater than the spacing between two adjacent fourth ventilation holes 1023 in each second air duct 102 along the circumference of the shell 100. Based on the aforementioned arrangement, the fourth ventilation holes 1023 of each second air duct 102 can be concentrated at different positions in the circumference of the second shell 120, and the distance between different second air ducts 102 can be increased. This is beneficial to further promote the flow of gas in the third air duct 103 around the periphery of the pot body 200, expand the contact area between the airflow and the pot body 200, and further improve the heat dissipation and pressure reduction efficiency of the pot body 200.

[0092] Alternatively, the spacing between two adjacent second air ducts 102 can be set along the circumference of the housing 100 to be equal to the spacing between two adjacent fourth ventilation holes 1023 in each second air duct 102. Based on the aforementioned arrangement, each second air duct 102 can be more evenly distributed along the circumference of the second housing 120, avoiding the phenomenon of localized low strength in the housing 100. This helps to reduce the weakening of the housing 100 strength caused by openings and ensures the structural reliability of the cooking appliance.

[0093] In some examples, in the projection plane perpendicular to the conduction direction of the first ventilation hole 1011, the orthographic projection of the portion of the air supply unit 300 between the first housing 110 and the second housing 120 is within the orthographic projection range of the first ventilation hole 1011.

[0094] In this technical solution, the opening range of the first ventilation hole 1011 is constrained. Based on the aforementioned setting, the air supply part 300 can be prevented from completely blocking the first ventilation hole 1011, thereby ensuring the gas flow of the first ventilation hole 1011. This is beneficial to ensuring the gas exchange efficiency between the first ventilation hole 1011 and the external environment, and thus provides a more reliable guarantee for the heat dissipation and pressure reduction efficiency of the pot body part 200.

[0095] like Figure 3 As shown, it can be understood that the first channel may include multiple first ventilation holes 1011, which are arranged in an array. This avoids the need for the first housing 110 to have large and continuous channels when the total conductive area of ​​the first ventilation holes 1011 is constant, thus ensuring the structural reliability of the first housing 110. When the first channel includes multiple first ventilation holes 1011, the conductive direction of the aforementioned first ventilation holes 1011 refers to the conductive direction of the first ventilation hole 1011 located in the center of the array, and the orthographic projection range of the aforementioned first ventilation holes 1011 refers to the orthographic projection range of the array area of ​​the aforementioned first ventilation holes 1011. It can be understood that the array form of the first ventilation holes 1011 can be various, such as a ring array, a linear array, a rectangular array, etc., and can be set according to actual needs; no further limitations are made here.

[0096] It is understood that the aforementioned "within the orthographic projection range of the first ventilation hole 1011" means that the orthographic projection of the portion of the air supply unit 300 between the first housing 110 and the second housing 120 is located within or coincides with the orthographic projection range of the first ventilation hole 1011.

[0097] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, in some examples, the second ventilation hole 1021 is opened on the peripheral wall of the first housing 110, and the second ventilation hole 1021 and the fourth ventilation hole 1023 have the same conduction direction.

[0098] In this technical solution, a second ventilation hole 1021 can be set on the peripheral wall of the first ventilation hole 1011, and the second ventilation hole 1021 and the fourth ventilation hole 1023 can be set to have the same direction of conduction. This can further reduce the deflection phenomenon when the gas flows in the second air duct 102, which is conducive to further reducing the friction loss and flow resistance of the airflow, and further improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0099] It is understandable that the aforementioned second ventilation hole 1021 and fourth ventilation hole 1023 having the same conduction direction means that the conduction directions of the second ventilation hole 1021 and fourth ventilation hole 1023 are parallel or coincident.

[0100] It is understood that when a plurality of second air ducts 102 are spaced apart along the circumference of the housing portion 100, each second air duct 102 may include a plurality of second ventilation holes 1021 arranged in an array, and at least a portion of the second ventilation holes 1021 in each second air duct 102 may be positioned in the same circumferential direction as at least a portion of the fourth ventilation holes 1023, and the conduction directions of the second ventilation holes 1021 and the fourth ventilation holes 1023 that are positioned in the same circumferential direction may be consistent.

[0101] It is understandable that the array form of the second ventilation hole 1021 can be various, such as a ring array, a linear array, a rectangular array, etc. The specific form can be set according to actual needs, and no further restrictions are imposed here.

[0102] like Figure 3 As shown, in some examples, the cooking appliance also includes a heating element 500 disposed between the air supply element 300 and the bottom wall of the pot body 200 for heating the pot body 200.

[0103] In this technical solution, the cooking appliance may further include a heating element 500 disposed between the air supply unit 300 and the bottom wall of the pot body 200. Based on the aforementioned arrangement, on the one hand, the cooking appliance can use the heating element 500 to provide heat to the pot body 200 during the cooking process to cook the food; on the other hand, when the air supply unit 300 is running, the airflow can flow through the heating element 500, thereby improving the heat dissipation efficiency of the heating element 500 and preventing the pot body 200 from absorbing a large amount of residual heat from the heating element 500 after cooking, which is conducive to further improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0104] It is understandable that when the third air duct 103 includes the aforementioned first channel section 1031, the heating unit 500 is disposed within the aforementioned first channel section 1031.

[0105] In some examples, the cooking appliance further includes: an air duct control unit for opening or closing the second air duct 102; a first control unit connected to the air supply unit 300, configured to control the operation of the air supply unit 300 when the air duct control unit opens the second air duct 102 and the heating unit 500 is closed; and a second control unit connected to the air supply unit 300, configured to control the operation of the air supply unit 300 when the air duct control unit closes the second air duct 102 and the heating unit 500 is turned on; wherein the air outlet of the air supply unit 300 is located within a third air duct.

[0106] In this technical solution, the first air duct 101 can be the aforementioned inlet channel, and correspondingly, the second air duct 102 can be the aforementioned outlet channel. The on / off state of the second air duct 102 can be controlled by the air duct control unit, and the air supply unit 300 can operate under the control of the first or second control unit. Based on the aforementioned configuration, during the process of the heating unit 500 providing heat to the pot body 200, the cooking appliance can shut off the second air duct 102 through the air duct control unit, thereby preventing the heat of the pot body 200 from being lost through the second air duct 102. Correspondingly, the air supply unit 300 can... The second control unit controls the operation of the air supply unit 300 to promote the flow of high-temperature gas in the third air duct 103 and form hot air that can act on the food in the pot body 200, which is beneficial to air frying the food in the pot body 200. When the heating unit 500 stops providing heat to the pot body 200, the cooking appliance can open the second air duct 102 through the air duct control unit and control the operation of the air supply unit 300 through the second control unit to promote the flow of gas in the third air duct 103 and accelerate the heat dissipation of the pot body 200 and the food in the pot body 200.

[0107] In some examples, the cooking appliance also includes: a lid portion disposed on the housing portion 100 for covering or opening the pot opening of the pot body portion 200; and a pressure relief valve disposed on the lid portion.

[0108] In this technical solution, the cooking appliance may further include a lid and a pressure relief valve. The lid is used to cover or open the pot opening of the pot body 200. During cooking, the lid can be used to cover the pot opening to ensure stable pressure inside the pot body 200. The pressure relief valve is located on the lid. When the lid covers the pot opening, the pressure relief valve is connected to the inside of the pot body 200. After cooking is completed, the internal pressure of the pot body 200 can be released by opening the pressure relief valve, so that the lid can open the pot opening.

[0109] It is understandable that the aforementioned pot opening is also the opening of the pot body 200.

[0110] Understandably, in practical applications, after cooking is completed, the air supply unit 300 can be used first to dissipate heat and reduce pressure in the pot body 200. After the internal pressure of the pot body 200 is reduced to a certain level, the pressure relief valve can be opened to release the residual pressure in the pot body 200. This helps to reduce the noise of the pressure relief valve when releasing pressure, avoids the user's anxiety caused by excessive noise, and helps to improve the user experience of the product.

[0111] Understandably, in practical applications, after cooking, the air supply unit 300 can be used to dissipate heat and reduce pressure on the pot body 200, so that the internal pressure of the pot body 200 is reduced to the external ambient pressure. This can avoid the user using the pressure relief valve and further reduce the noise generated by the cooking appliance when releasing pressure.
