[0057] 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.

[0058] like Figures 1 to 12 As shown, a cooking appliance is proposed according to an embodiment of the present disclosure, comprising: a shell portion 100, wherein a first air duct 101 and a second air duct 102 are formed on the peripheral 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, wherein at least a portion of the third air duct 103 surrounds the periphery of the pot body portion 200, and both the first air duct 101 and the second air duct 102 are connected to the third air duct 103; and an air supply portion 300 disposed within the first air duct 101, wherein the air supply portion 300 includes a guide structure 310 having a guide channel 301 formed therein; wherein one end of the first air duct 101 connected to the third air duct 103 is located between the guide channel 301 and the third air duct 103.

[0059] 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, both located on the peripheral 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 on the periphery of the pot body portion 200. The air supply portion 300 is disposed in the shell portion 100 and located within the first air duct 101, and the first air duct 101 communicates with the first air duct 102. One end of the three air ducts 103 is located between the air supply section 300's guide channel 301 and the third air duct 103. Based on the aforementioned configuration, the cooking appliance provided in this embodiment can utilize the aforementioned air ducts to provide space for gas flow. Thus, in practical applications, after the cooking appliance finishes cooking the food, it can provide power for the gas to flow through the aforementioned air ducts through the air supply section 300. When the gas flows along the aforementioned third air duct 103, it can generate heat exchange with the pot body 200, improve the heat dissipation efficiency of the pot body 200, and reduce the temperature of the pot body 200 and the food inside the pot body 200, so as to facilitate the user to take out the food after cooking and reduce the risk of burns when the user takes out the food.

[0060] 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.

[0061] 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 reduce the internal pressure of the pot body 200 by lowering the temperature of the pot body 200, which 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.

[0062] It should be noted that the first air duct 101 and the second air duct 102 are provided on the peripheral wall of the aforementioned housing portion 100. This means that one end of the first air duct 101 connected to the third air duct 103 is located on the peripheral wall of the housing portion 100, and one end of the second air duct 102 connected to the third air duct 103 is located on the peripheral wall of the housing portion 100. Correspondingly, the other end of the first air duct 101 and the other end of the second air duct 102 may be located on the bottom wall or the peripheral wall of the housing portion 100.

[0063] 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 operating, it can drive gas from the first air duct 101 to the third air duct 103 or drive 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 an inlet channel for gas from the external environment to flow into the housing 100, and correspondingly, the other can serve as an outlet channel for gas to flow out of the housing 100, specifically related to the air supply direction of the air supply unit 300. For example, as... Figure 12 As shown, when the air supply unit 300 supplies air from the first air duct 101 to 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 utilize 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, when the air supply unit 300 supplies air from the third air duct 103 to the first air duct... When air is supplied at position 101, the air supply unit 300 can draw in gas from the third air duct 103 and discharge it from the shell part 100 through the first air duct 101, thereby increasing the gas flow rate around the pot body 200 and accelerating its heat dissipation. Correspondingly, gas from the external environment can enter the shell part 100 through the second air duct 102 and flow to the third air duct 103 to replenish the third air duct 103 with cooler gas, ensuring the heat dissipation efficiency of the pot body 200. 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. It should be noted that... Figure 12 The dashed curve with an arrow in the middle is used to schematically represent the direction of gas flow.

[0064] It is understood that the cooking appliance provided in this disclosure, by providing at least a portion of the third air duct 103 around the periphery of the pot body 200, can cause the gas to flow around the periphery of the pot body 200 after entering the third air duct 103 when the air supply unit 300 is running. This can increase the distribution range of the air duct inside the shell part 100, which is beneficial to increasing the contact area between the airflow and the pot body 200, thereby improving the cooling and depressurization efficiency of the pot body 200.

[0065] It is understood that by placing the air supply unit 300 inside the first air duct 101, the cooking appliance provided in this disclosure can create a certain gap between the air supply unit 300 and the pot body 200, which helps to reduce the impact of the heat from the pot body 200 on the air supply unit 300, reduce the risk of overheating of the air supply unit 300, and thus reduce the probability of damage to the air supply unit 300.

[0066] It should be noted that in traditional technology, some cooking utensils usually have an air duct on the outer pot and a fan at one end of the air duct. The fan delivers gas into the annular gap between the outer and inner pots to cool the inner pot. In order to avoid the fan from contacting the outer pot when it is running, there is often a certain gap between the air outlet side of the fan and the outer pot. As a result, some of the gas output by the fan can easily escape through the aforementioned gap and fail to flow into the aforementioned annular gap through the air duct. This results in a large loss of airflow from the fan and low efficiency of air cooling and pressure reduction.

[0067] Compared to the aforementioned conventional technologies, the cooking appliance provided in this disclosure, based on the aforementioned arrangement of the guide channel 301, allows the air supply unit 300 to draw in gas from the external environment through the first air duct 101 and transport the gas through the guide channel 301 to the end of the first air duct 101 connected to the third air duct 103. This enables the gas to be supplied to the third air duct 103 more concentratedly after being driven by the air supply unit 300, preventing the airflow from escaping within the first air duct 101, thereby improving the efficiency of the air supply unit. The air supply unit 300 promotes the flow of gas within the third air duct 103, improving the heat dissipation efficiency of the airflow on the pot body 200. Alternatively, when the air supply unit 300 supplies air from the third air duct 103 to the first air duct 101, the gas, after flowing through the first air duct 101 and connecting to the third air duct 103, can flow into the guide channel 301, thereby more quickly converging into the air supply unit 300, improving the suction efficiency of the air supply unit 300 on the gas within the third air duct 103, and further increasing the gas flow rate within the third air duct 103, thus improving the heat dissipation efficiency of the airflow on the pot body 200. Therefore, the cooking appliance provided in this embodiment can improve the driving efficiency of the air supply unit 300 on the gas surrounding the pot body 200, improve the operating efficiency of the air supply unit 300, and facilitate more efficient use of airflow to dissipate heat from the pot body 200, saving energy consumption of the air supply unit 300.

[0068] like Figures 1 to 4 and Figures 9 to 11 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; and 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 second housing 120; and the second air duct 102 further including a fourth ventilation hole 1023 opened in the second housing 120; wherein, the pot body 200 is disposed within the second housing 120; the air supply part 300 is disposed between the first housing 110 and the second housing 120; and one end of the flow guide channel 301 is arranged facing the third ventilation hole.

[0069] 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.

[0070] 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 is connected to the aforementioned third air duct 103 located at the aforementioned third ventilation hole 1013. 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 is connected to the aforementioned third air duct 103 located at the aforementioned fourth ventilation hole 1023. When the air supply unit 300 is operating, gas from 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. It is understood that the aforementioned third ventilation hole 1013 and the aforementioned fourth ventilation hole 1023 are formed on the peripheral wall of the aforementioned first housing 110.

[0071] The aforementioned air supply unit 300 can be disposed between the first housing 110 and the second housing 120, that is, an installation space is formed between the first housing 110 and the second housing 120. The aforementioned air supply unit 300 is disposed in the aforementioned installation space, so that when the air supply unit 300 supplies air from the first air duct 101 to the third air duct 103, when the air supply unit 300 is running, the gas can enter the first air duct 101 through the first ventilation hole 1011 and flow to the third air duct 103 through the third ventilation hole 1013, and then be discharged through the second air duct 102. When the air supply unit 300 supplies air from the third air duct 103 to the first air duct 101, when the air supply unit 300 is running, the gas can flow from the second air duct 102 to the third air duct 103 and enter the first air duct 101 through the third ventilation hole 1013, and then be discharged through the first ventilation hole 1011. At the same time, based on the aforementioned arrangement, it is also beneficial to improve the utilization rate of the internal space of the housing 100 and improve the structural compactness and miniaturization level of the cooking appliance. It is understandable that the aforementioned first air duct 101 also includes the aforementioned installation space.

[0072] One end of the aforementioned airflow channel 301 is arranged toward the third ventilation hole 1013, which can enhance the airflow channel continuity between the three ventilation holes and the air supply unit 300, prevent gas from escaping in the aforementioned installation space, and help improve the gas driving efficiency of the air supply unit 300 in the third air duct 103, providing a more reliable guarantee for the heat dissipation and pressure reduction efficiency of the pot body 200.

[0073] It is understood that 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.

[0074] like Figure 2 , Figures 5 to 7 , Figure 10 and Figure 11 As shown, in some examples, the air supply unit 300 further includes a fan 320 disposed in the flow guiding structure 310, and the flow guiding channel 301 is located between the fan 320 and the third ventilation hole 1013.

[0075] In this technical solution, the air supply unit 300 may further include a fan 320 disposed on the flow guide structure 310. The fan 320 is located on the side of the aforementioned flow guide channel 301 away from the third ventilation hole 1013. Thus, the fan 320 can be connected to the third ventilation hole 1013 through the flow guide channel 301. When the air inlet of the fan 320 faces the flow guide channel 301, the air intake efficiency of the air supply unit 300 can be guaranteed, thereby accelerating the flow velocity in the third air duct 103 and saving the energy consumption of the air supply unit 300. When the air outlet of the air supply unit 300 faces the flow guide channel 301, it can be guaranteed that the gas discharged from the air supply unit 300 flows into the third air duct 103 through the third ventilation hole 1013, preventing the gas from being lost to other parts. This is beneficial to ensuring the output efficiency of the air supply unit 300, saving the energy consumption of the air supply unit 300, and providing a guarantee for the heat dissipation and pressure reduction efficiency of the pot body 200.

[0076] like Figure 12 As shown, in some examples, the length of the guide channel 301 increases in the circumferential direction of the boiler body 200 along the direction from the fan 320 to the third ventilation hole 1013.

[0077] In this technical solution, the length of the guide channel 301 in the circumferential direction of the pot body 200 can be increased along the direction from the fan 320 to the third ventilation hole 1013. Based on the aforementioned arrangement, the guide channel 301 can be gradually expanded in the circumferential direction of the pot body 200 along the direction close to the third air duct 103. This facilitates the gas to flow directly around the circumference of the pot body 200 after flowing out of the guide channel 301, or to make the gas in the third air duct 103 form a tendency to flow around the pot body 200 before flowing into the guide channel 301. This is beneficial to further increase the contact area between the airflow and the pot body 200, improve the heat dissipation and pressure reduction efficiency of the pot body 200, and at the same time reduce the flow resistance of the airflow during the transition between the first air duct 101 and the third air duct 103, thereby reducing the flow loss along the airflow path.

[0078] In some examples, in the projection plane perpendicular to the conduction direction of the third ventilation hole 1013, the orthographic projection of the third ventilation hole 1013 is located within the orthographic projection range of the flow channel 301.

[0079] In this technical solution, the coverage area of ​​the guide channel 301 is constrained. Based on the aforementioned arrangement of this technical solution, when the air supply unit 300 drives the gas to flow from the first air duct 101 to the third air duct 103, the gas flow rate of the third ventilation hole 1013 is guaranteed, preventing the gas output by the air supply unit 300 from escaping to other areas. This is beneficial to improving the gas driving efficiency of the air supply unit 300 in the third air duct 103, thereby providing a more reliable guarantee for the heat dissipation and pressure reduction efficiency of the pot body 200. Alternatively, when the air supply unit 300 drives the gas to flow from the third air duct 103 to the first air duct 101, the gas supply efficiency in drawing gas from the third air duct 103 is guaranteed, thereby providing a more reliable guarantee for the heat dissipation and pressure reduction efficiency of the pot body 200.

[0080] It is understood that the orthographic projection of the aforementioned third ventilation hole 1013 is located within the orthographic projection range of the flow channel 301, that is, the orthographic projection of the third ventilation hole 1013 is within the boundary of the orthographic projection range of the flow channel 301, or coincides with the boundary of the orthographic projection range of the flow channel 301.

[0081] like Figures 5 to 8 , Figure 10 and Figure 11 As shown, in some examples, the flow guiding structure 310 includes: a support member 311, which has an installation groove and a vent communicating with the installation groove, a fan 320 is disposed in the installation groove, and the air inlet side or air outlet side of the fan 320 is arranged facing the vent; a flow guiding member 312, which is disposed on the support member 311 and located between the support member 311 and the second housing 120, the flow guiding member 312 has a flow guiding channel 301, and the vent communicating with the flow guiding channel 301; and a connector 313, which is disposed on the support member 311 and connected to the first housing 110.

[0082] In this technical solution, the aforementioned airflow guiding structure 310 may include a support member 311, an airflow guiding member 312, and a connector 313. The connector 313 and the airflow guiding member 312 are both disposed on the support member 311. The support member 311 is used to install the aforementioned fan 320, and the connector 313 is connected to the first housing 110, so that the air supply part 300 can be disposed on the housing part 100 through the connector 313, thereby ensuring the positional stability of the air supply part 300. The airflow guiding member 312 is between the support member 311 and the second housing 120, and the aforementioned airflow guiding channel 301 is formed. The air inlet side or air outlet side of the fan 320 is connected to the airflow guiding channel 301 through the ventilation port on the support member 311, thereby facilitating the connection of the gas channel between the fan 320 and the third ventilation hole 1013, and facilitating the use of the fan 320 to drive the gas flow in the third air duct 103 to dissipate heat and reduce pressure on the pot body part 200.

[0083] It is understandable that the shape parameters of the flow channel 301 are limited by the structure of the flow guide 312, so in practical applications, flow channels 301 with different shape parameters can be obtained by designing the flow guide 312 in different ways.

[0084] like Figures 5 to 7 As shown, in some examples, the guide 312 is a tubular structure, with one end of the guide 312 arranged around the vent and the other end facing the third vent 1013.

[0085] In this technical solution, the aforementioned guide member 312 can be a tubular structure, and one end of the guide member 312 can be arranged around the vent, while the other end faces the third vent 1013. Correspondingly, the aforementioned guide channel 301 is formed inside the guide member 312. Based on the aforementioned arrangement, while ensuring the guiding effect of the guide channel 301 on the gas, the shape regularity of the guide channel 301 can be improved, the forming difficulty of the guide member 312 can be reduced, and the airflow can be concentrated at the fan 320. This facilitates the connection of the gas channel between the guide channel 301 and the third vent 1013, thus ensuring the improvement of the driving efficiency of the air supply unit 300.

[0086] It is understandable that, such as Figures 5 to 7 As shown, when the guide member 312 is a tubular structure, the outer contour of the end of the guide member 312 facing the third ventilation hole 1013 can be combined with the outer contour of the peripheral wall of the first housing 110 to improve the structural compatibility between the guide member 312 and the second housing 120 and avoid the formation of excessively large gaps between the guide member 312 and the second housing 120.

[0087] like Figures 8 to 11 As shown, in some examples, the flow guide 312 is a plate-like structure that extends circumferentially along the second housing 120, and the flow channel 301 is opened on the side of the flow guide 312 facing the third ventilation hole 1013.

[0088] In this technical solution, the aforementioned guide member 312 can be a plate-like structure extending circumferentially along the second housing 120, and the aforementioned guide channel 301 can be opened on the side of the guide member 312 facing the third ventilation hole 1013. Based on the aforementioned arrangement, when the fan 320 is running, the gas in the guide channel 301 can generate a flow trend around the second housing 120, thereby making the airflow direction in the guide channel 301 more adaptable to the extension direction of the third air duct 103. This helps to reduce the resistance of the gas during the transition between the third air duct 103 and the guide channel 301, and facilitates the airflow to generate a flow around the pot body 200 in the third air duct 103. This is beneficial to expanding the contact area between the airflow and the pot body 200, and further improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0089] It is understandable that, such as Figures 8 to 11 As shown, when the guide member 312 is a plate-shaped structure, the extension length of the guide member 312 along the circumference of the second housing 120 can be combined with the distribution range length of the third ventilation hole 1013 along the circumference of the second housing 120 to improve the coverage of the guide channel 301 on the third ventilation hole 1013. This helps to ensure the driving efficiency of the air supply unit 300, and also helps to expand the distribution range length of the third ventilation hole 1013 along the circumference of the second housing 120. This helps to promote the gas flow at different circumferential positions in the third air duct 103, and further expands the contact area between the airflow and the pot body 200, improving the heat transfer efficiency between the airflow and the pot body 200, and providing a more reliable guarantee for improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0090] It is understandable that, such as Figure 8 As shown, when the guide member 312 is a plate-shaped structure, the guide channel 301 can be a groove-shaped channel opened along the extension direction of the guide member 312. Along the direction from the fan 320 to the third ventilation hole 1013, the aforementioned groove-shaped channel has an opening at one end near the third ventilation hole 1013, and the end near the fan 320 is connected to the ventilation opening. This can improve the distribution range of the guide channel 301 while ensuring that the guide channel 301 is connected to the third ventilation hole 1013.

[0091] like Figures 2 to 4 , Figures 9 to 11 As shown, in some examples, the first air duct 101 includes a plurality of first ventilation holes 1011 and a plurality of third ventilation holes 1013, which are arranged in an array; and / or the second air duct 102 includes a plurality of second ventilation holes 1021 and a plurality of fourth ventilation holes 1023, which are arranged in an array.

[0092] In this technical solution, the first air duct 101 includes a plurality of first ventilation holes 1011 and a plurality of third ventilation holes 1013, and the plurality of first ventilation holes 1011 and the plurality of third ventilation holes 1013 are arranged in an array. Based on the aforementioned arrangement, when the total conduction area of ​​the first air duct 101 is fixed, the method of dispersing the first ventilation holes 1011 and the third ventilation holes 1013 can avoid opening excessively large and continuous channels on the shell part 100. This is beneficial to reduce the weakening of the shell part 100 caused by opening holes, ensuring the structural reliability of the cooking appliance. At the same time, it is beneficial to improve the regularity of the first ventilation holes 1011 and the third ventilation holes 1013, ensuring the aesthetics of the first shell 110 and the second shell 120.

[0093] It is understandable that the array form of the first ventilation hole 1011 and the third ventilation hole 1013 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.

[0094] In this technical solution, the second air duct 102 includes a plurality of second ventilation holes 1021 and a plurality of fourth ventilation holes 1023, and the plurality of second ventilation holes 1021 and the plurality of fourth ventilation holes 1023 are arranged in an array. Based on the aforementioned arrangement, when the total conduction area of ​​the second air duct 102 is fixed, the method of dispersing the second ventilation holes 1021 and the fourth ventilation holes 1023 can avoid opening excessively large and continuous channels on the shell part 100. This is beneficial to reduce the weakening of the shell part 100 caused by opening holes, ensuring the structural reliability of the cooking appliance. At the same time, it is beneficial to improve the regularity of the second ventilation holes 1021 and the fourth ventilation holes 1023, ensuring the aesthetics of the first shell 110 and the second shell 120.

[0095] It is understandable that the array form of the second ventilation hole 1021 and 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.

[0096] like Figure 3 As shown, in some examples, the first ventilation hole 1011 and the third ventilation hole 1013 have the same conduction direction; and / or the second ventilation hole 1021 and the fourth ventilation hole 1023 have the same conduction direction.

[0097] In this technical solution, the conduction directions of the first ventilation hole 1011 and the third ventilation hole 1013 of the first air duct 101 can be set to be consistent, that is, the conduction directions of the first ventilation hole 1011 and the third ventilation hole 1013 of the first air duct 101 are arranged to coincide or parallel, which helps to reduce the deflection of gas in the first air duct 101, reduce the flow loss of air along the air in the first air duct 101, save the energy consumption of the air supply unit 300, and help to improve the gas exchange efficiency between the cooking appliance and the external environment, and improve the heat dissipation and pressure reduction efficiency of the pot body 200.

[0098] It is understandable that when there is more than one first air duct 101, the first ventilation hole 1011 and the third ventilation hole 1013 of the same first air duct 101 can be set to have the same conduction direction.

[0099] In this technical solution, the conduction directions of the second ventilation hole 1021 and the fourth ventilation hole 1023 of the second air duct 102 can be set to be consistent, that is, the conduction directions of the second ventilation hole 1021 and the fourth ventilation hole 1023 of the second air duct 102 are arranged to coincide or parallel, which helps to reduce the deflection of gas in the second air duct 102, reduce the flow loss of air along the air in the second air duct 102, save the energy consumption of the air supply unit 300, and help to improve the gas exchange efficiency between the cooking appliance and the external environment, and improve the heat dissipation and pressure reduction efficiency of the pot body 200.

[0100] It is understandable that when there is more than one second air duct 102, the second ventilation hole 1021 and the fourth ventilation hole 1023 of the same second air duct 102 can be set to have the same conduction direction.

[0101] It is understandable that, while setting the first ventilation hole 1011 and the third ventilation hole 1013 of the first air duct 101 to have the same conduction direction, the second ventilation hole 1021 and the fourth ventilation hole 1023 of the second air duct 102 can also have the same conduction direction, thereby further reducing the loss of gas when entering and exiting the shell part 100, improving the gas exchange efficiency between the cooking appliance and the external environment, and improving the heat dissipation and pressure reduction efficiency of the pot body part 200.

[0102] like Figure 1 As shown, in some examples, along the circumference of the pot body portion 200, the shell portion 100 is provided with at least two first air ducts 101 spaced apart, and each first air duct 101 is provided with an air supply portion 300.

[0103] In this technical solution, at least two first air ducts 101 are spaced apart along the circumference of the pot body 200, and an air supply unit 300 is provided at each first air duct 101. Based on the aforementioned arrangement, on the one hand, the distribution range of the air ducts inside the shell body 100 can be further improved, which is conducive to increasing the contact area and heat transfer efficiency between the airflow and the pot body 200. Moreover, based on the circumferential positional differences between the multiple first air ducts 101, it is conducive to promoting the flow of gas around the pot body 200 in the third air duct 103, thereby enhancing the heat dissipation and pressure reduction efficiency of the pot body 200. On the other hand, it can also improve the driving performance of the cooking appliance on the gas, improve the gas exchange efficiency between the cooking appliance and the external environment, reduce the limitation of airflow loss along the way on the heat dissipation and pressure reduction efficiency, and further improve the heat dissipation and pressure reduction efficiency of the pot body 200.

[0104] It should be noted that, as Figure 10 and Figure 11As shown, the air supply directions of each air supply unit 300 can be consistent, that is, each air supply unit 300 can drive gas from the first air duct 101 to the third air duct 103 or drive gas from the third air duct 103 to the first air duct 101, thereby helping to ensure the stability of the gas flow field in the third air duct 103 and increase the gas flow rate in the third air duct 103, improving the heat dissipation effect of the gas on the pot body 200; or, the air supply directions of each air supply unit 300 can be opposite, that is, some... The air supply unit 300 can drive gas from the first air duct 101 to the third air duct 103, and some air supply units 300 can drive gas from the third air duct 103 to the first air duct 101, which helps to accelerate the air intake and exhaust efficiency in the air supply unit 300. Furthermore, based on the circumferential position difference between each air supply unit 300, it is more conducive to the gas flowing around the periphery of the pot body 200 in the third air duct 103, thereby increasing the heat transfer efficiency and heat dissipation effect between the airflow and the pot body 200.

[0105] like Figure 12 As shown, in some examples, at least one second air duct 102 is provided on both sides of at least one first air duct 101 along the circumference of the pot body 200.

[0106] In this technical solution, the number of first air ducts 101 can be one or more. When there is only one first air duct 101, at least one second air duct 102 is provided on both sides of the pot body portion 200 in the circumferential direction. Alternatively, when there are multiple first air ducts 101, at least one of the multiple first air ducts 101 is provided with at least one second air duct 102 on both sides of the pot body portion 200 in the circumferential direction. It is easy to understand that the second air ducts 102 corresponding to the same first air duct 101 are located on the pot body portion 200. There is a difference in the circumferential position of the 00; based on the aforementioned settings, when the air supply section 300 is running, the difference in the circumferential position between the first air duct 101 and the second air duct 102 can be used to cause the gas to flow around the periphery of the pot body section 200 after entering the third air duct 103, thereby reducing the flow resistance of the airflow, improving the smoothness of the airflow in the third air duct 103, which is conducive to increasing the gas flow rate in each air duct, and can also increase the distribution range of the air ducts inside the shell section 100, which is conducive to increasing the contact area between the airflow and the pot body section 200, thereby improving the cooling and depressurization efficiency of the pot body section 200.

[0107] It is understood that, based on the aforementioned configuration of this technical solution, at least one first air duct 101 can have corresponding second air ducts 102 on both sides of the pot body 200 circumferentially. Thus, when the first air duct 101 serves as the aforementioned inlet channel, it can ensure that the gas enters the third air duct 103 and forms a diversion; or, when the second air duct 102 serves as the aforementioned inlet channel, it can ensure that the gas in the external environment enters the third air duct 103 at different positions on the pot body 200 circumferentially and converges back to the first air duct 101, thereby providing… The contact area between the pot body 200 and the gas in the third air duct 103 is guaranteed, reducing the temperature difference in the circumferential direction of the pot body 200. It can also increase the conduction area between the third air duct 103 and the external environment, improving the gas flow efficiency between the third air duct 103 and the external environment, thereby improving the heat dissipation efficiency of the pot body 200 and the food inside the pot body 200. At the same time, it can reduce the positional accuracy requirements of the first air duct 101 and the second air duct 102 in the circumferential direction of the pot body 200, and reduce the processing difficulty of the shell part 100.

[0108] like Figure 3 As shown, in some examples, the cooking appliance also includes a heating element 500 for heating the pot body 200.

[0109] In this technical solution, the cooking appliance may also include a heating element 500, so that, based on the aforementioned configuration, the cooking appliance can use the heating element 500 to provide heat to the pot body 200 during the cooking process to achieve the cooking of the ingredients.

[0110] 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.

[0111] 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.

[0112] It is understandable that the aforementioned pot opening is also the opening of the pot body 200.

[0113] 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.

[0114] 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.

[0115] like Figure 1 As shown, in some examples, the cooking appliance also includes a panel 400 disposed on the peripheral wall of the first housing 110; wherein, along the circumference of the pot body 200, the first air duct 101 and the second air duct 102 are both arranged at intervals from the panel 400.

[0116] In this technical solution, the cooking appliance may also include a panel 400 disposed on the peripheral wall of the first housing 110, which is beneficial to further improve the aesthetics of the cooking appliance. Along the circumference of the pot body 200, the first air duct 101 and the second air duct 102 are spaced apart from the panel 400, which is beneficial to reduce the influence of the panel 400 on the air intake and exhaust of the cooking appliance, ensure the gas exchange efficiency between the cooking appliance and the external environment, and prevent the panel 400 from contacting the high-temperature gas discharged from the cooking appliance, which is beneficial to extend the service life of the panel 400.

[0117] It is understood that the aforementioned panel 400 may include a panel 400 body and a button assembly, wherein the panel 400 body is disposed on the first housing 110, and the button assembly is disposed on the panel 400 body so that the user can operate the cooking appliance through the button assembly; the panel 400 may also include a display assembly disposed on the aforementioned panel 400 body so that the operating information of the cooking appliance can be displayed through the display assembly.
