[0003] After cooking, the food inside the cooking space is usually quite hot, making it difficult for users to eat. Opening the cooking space while the food is hot also increases the risk of burns. Some cooking appliances are equipped with cooling devices for air cooling of the pot body. However, in practical applications, it has been found that these cooling devices have poor cooling efficiency and take a long time to cool down, which is detrimental to the user experience. Furthermore, it has been found that the airflow loss during operation of these air cooling devices is high, resulting in low cooling efficiency and a long cooling time, affecting the product's energy efficiency and further impacting the user experience.

[0059] Compared to the prior art, the technical solutions according to other embodiments of this disclosure include at least the following beneficial effects: The cooking appliance provided in the embodiments of this disclosure includes a shell portion, a pot body portion, and an air supply portion.

In practical applications, after the cooking appliance has finished cooking the food, it can provide power for the gas to flow through the aforementioned air ducts through the air supply portion. When the gas flows along the aforementioned third air duct, it can generate heat exchange with the pot body portion, improving the heat dissipation efficiency of the pot body portion. Creating a certain distance between the air supply section and the pot body helps reduce the impact of heat from the pot body on the air supply section, lowering the risk of overheating.

Based on the design of the flow guide channel, the driving efficiency of the air supply section on the gas within the third air duct can be improved, reducing airflow loss and increasing the operating efficiency of the air supply section. Therefore, it is beneficial to utilize airflow more efficiently to dissipate heat from the pot body, reducing the energy consumption of the air supply section. Attached Figure Description

[0093] 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.

[0094] As shown in Figures 1 to 11, a cooking appliance is provided according to an embodiment of this disclosure, comprising: a shell portion 100 having a first air duct 101 and a second air duct 102; a pot body portion 200 disposed within the shell portion 100, a third air duct 103 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 communicating with the third air duct 103; and an air supply portion 300 disposed at the first air duct 101. Along the circumference of the pot body portion 200, at least one second air duct 102 is provided on each side of at least one first air duct 101.

[0095] The cooking appliance provided in this embodiment includes a housing portion 100, a pot body portion 200, and an air supply portion 300. The housing portion 100 has a first air duct 101 and a second air duct 102, and the number of second air ducts 102 is at least two. The pot body portion 200 is disposed inside the housing portion 100, and a third air duct 103 is formed between the pot body portion 200 and the housing portion 100, communicating with the first air ducts 101 and the second air ducts 102. At least a portion of the third air duct 103 is located around the periphery of the pot body portion 200, and at least one second air duct 102 is provided on each side of at least one first air duct 101 along the circumference of the pot body portion 200. The air supply portion 300 is disposed in the housing portion 100 and located at the first air duct 101. Based on the above configuration, the cooking appliance provided in this embodiment can utilize the aforementioned air ducts to provide space for gas flow. In practical applications, after cooking food, the cooking appliance can provide power for gas flow through the aforementioned air ducts via the air supply portion 300. As the gas flows along the aforementioned third air duct 103, it can exchange heat with the pot body 200, thereby improving the heat dissipation efficiency of the pot body 200. This can reduce the temperature of the pot body 200 and the food inside it, making it easier for users to eat after cooking and reducing the risk of burns when eating.

[0096] 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, etc. Both the aforementioned shell portion 100 and the aforementioned pot body portion 200 can be groove-shaped structures, meaning both the shell portion 100 and the pot body portion 200 can be hollow internally and open at one end. The internal space of the pot body portion 200 can serve as a cooking space, and the internal space of the shell portion 100 can serve as a accommodating space to house the pot body portion 200. The positions of the aforementioned first air duct 101 and the aforementioned second air duct 102 on the pot body portion 200 can be set according to actual needs; that is, the aforementioned first air duct 101 can be located on the peripheral wall or bottom wall of the pot body portion 200. The aforementioned second air duct 102 can also be located on the bottom wall or peripheral wall of the pot body portion 200. The bottom wall of the aforementioned shell portion 100 is the side opposite the open end of the shell portion 100. The peripheral wall of the aforementioned shell portion 100 is the portion between the opening of the shell portion 100 and the bottom wall. In some embodiments, the bottom wall of the pot body portion 200 is the side opposite the opening of the pot body portion 200. The peripheral wall of the pot body portion 200 is the portion between the opening of the pot body portion 200 and the bottom wall. The periphery of the pot body portion 200 is the outer side of the peripheral wall of the pot body portion 200.

[0097] 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, reduces the safety burden on the user during operation, and improves the user experience of the product.

[0098] It should be noted that the first air duct 101 is provided on the bottom wall of the housing portion 100, meaning that one end of the first air duct 101, which connects to the third air duct 103, is located on the bottom wall of the housing portion 100. 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. Correspondingly, the second air duct 102 is provided on the peripheral wall of the housing portion 100, meaning that one end of the second air duct 102, which connects to the third air duct 103, is located on the peripheral wall of the housing portion 100, and the other end of the second air duct 102 can be located on the bottom wall or the peripheral wall of the housing portion 100.

[0099] It is understood that both the first air duct 101 and the second air duct 102 are connected to the third air duct 103, meaning that the first air duct 101 is connected to the second air duct 102 via 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. Therefore, one of the first air duct 101 and the second air duct 102 can serve as an inlet channel for gas from the external environment to flow into the housing 100. Correspondingly, the other of the first air duct 101 and the second air duct 102 can serve as an outlet channel for gas to flow out of the housing 100, and can be configured according to the air supply direction of the air supply unit 300. In some embodiments, as shown in FIG11, 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 into the aforementioned third air duct 103, thereby utilizing 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. The second air duct 102 can serve as the aforementioned outlet channel. In some embodiments, as shown in FIG10, when the air supply unit 300 supplies air from the third air duct 103 to the first air duct 101, the air supply unit 300 can draw in gas from the third air duct 103 during operation 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 the heat dissipation of the pot body 200. Accordingly, gas from the external environment can enter the shell section 100 through the second air duct 102 and flow to the third air duct 103 to replenish the third air duct 103 with lower-temperature gas, ensuring the heat dissipation efficiency of the pot body section 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 the dashed curves with arrows in Figures 10 and 11 are used to schematically represent the direction of gas flow.

[0100] It is understood that the aforementioned provision of at least one second air duct 102 on both sides of at least one first air duct 101 along the circumference of the pot body 200 refers to the fact that the number of first air ducts 101 can be one or more, and when there is only one first air duct 101, at least one second air duct 102 is provided on both sides of the first air duct 101 along the circumference of the pot body 200. In some embodiments, 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 200 along the circumference of the pot body 200. It is easy to understand that the positions of the second air ducts 102 corresponding to the same first air duct 101 in the circumferential direction of the pot body 200 may differ.

[0101] It is understood that the cooking appliance provided in this disclosure has at least a partial third air duct 103 surrounding the periphery of the pot body 200. At least one first air duct 101 is provided along the circumference of the pot body 200, and at least one second air duct 102 is respectively provided on both sides. Therefore, when the air supply unit 300 is running, the circumferential positional difference between the first air duct 101 and the second air duct 102 can be used to promote gas flow around the periphery of the pot body 200 after entering the third air duct 103, thereby reducing airflow resistance and improving the smoothness of airflow within the third air duct 103. This is beneficial for increasing the gas flow rate in each air duct and improving the distribution range of air ducts inside the shell portion 100. It also helps to increase the contact area between the airflow and the pot body 200, thereby improving the cooling and depressurization efficiency of the pot body 200.

[0102] It should be noted that some cooking appliances in traditional technology are equipped with fans. The outer shell of the cooking appliance has an air inlet and an air outlet. Both the air inlet and the air outlet are connected to the annular gap between the inner and outer pots of the cooking appliance, and the fan drives gas to flow into the annular gap through the air inlet and out through the air outlet. There is only one fan, one air inlet, and one air outlet, and the air inlet and air outlet are arranged at approximately 180° intervals along the circumference of the inner pot, so that the gas can be evenly divided into two streams after entering the annular gap through the air inlet, and the two air streams flow clockwise and counterclockwise along the circumference of the inner pot, respectively, towards the air outlet. However, in practical applications, it has been found that the above-mentioned traditional technology requires high precision in the positioning of the air inlet and air outlet. If the angle between the air inlet and outlet along the circumference of the inner pot deviates significantly from 180°, the resistance encountered by the two airflows during the flow process will be significantly different. This may even cause the gas to be difficult to split after entering the annular gap, resulting in a reduction in the contact area between the inner pot and the gas in the annular gap. Consequently, the difference between different areas along the circumference of the inner pot will increase, and the heat dissipation efficiency for food will be low.

[0103] Compared to the aforementioned conventional technologies, the cooking appliance provided in this disclosure, based on the aforementioned configuration, allows at least one first air duct 101 to have corresponding second air ducts 102 on both sides of the pot body 200 circumferentially. Therefore, when the first air duct 101 serves as the aforementioned inlet channel, it ensures that gas enters the third air duct 103 and forms a branch flow. In some embodiments where the second air duct 102 serves as the aforementioned inlet channel, it ensures that gas from the external environment enters the third air duct 103 at different positions circumferentially on the pot body 200 and converges back to the first air duct 101. Therefore, it ensures a sufficient contact area between the pot body 200 and the gas within the third air duct 103, thereby reducing the temperature difference circumferentially on the pot body 200 and increasing the conduction area between the third air duct 103 and the external environment. This improves the gas flow efficiency between the third air duct 103 and the external environment, thereby increasing the heat dissipation efficiency of the pot body 200 and the food within it. 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, thereby reducing the machining difficulty of the shell part 100.

[0104] As shown in Figures 4, 9 to 11, in some examples, at least two first air ducts 101 are spaced apart along the circumference of the pot body portion 200. Each first air duct 101 is provided with an air supply portion 300.

[0105] In some embodiments, at least two first air ducts 101 are spaced apart along the circumference of the pot body 200. 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 increased, which is beneficial to increasing the contact area and heat transfer efficiency between the airflow and the pot body 200; and based on the circumferential positional differences between the multiple first air ducts 101, and the circumferential positional differences between the first air ducts 101 and the second air duct 102, it is more conducive to promoting gas flow around the pot body 200 within the third air duct 103, enhancing the heat dissipation and pressure reduction efficiency of the pot body 200. On the other hand, it can also improve the gas driving performance of the cooking appliance and enhance the gas exchange efficiency between the cooking appliance and the external environment. This reduces the limitation of airflow loss along the path on heat dissipation and pressure reduction efficiency, thereby further improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0106] It should be noted that, as shown in Figures 10 and 11, the air supply direction 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. This helps 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, thereby improving the heat dissipation effect of the gas on the pot body 200. In some embodiments, the air supply direction of each air supply unit 300 can be opposite, that is, some air supply units 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. This helps to accelerate the air intake and exhaust efficiency in the air supply units 300. Based on the circumferential positional differences between the various air supply sections 300, it is more conducive to the flow of gas around the periphery of the pot body section 200 within the third air duct 103, thereby increasing the heat transfer efficiency and heat dissipation effect between the airflow and the pot body section 200.

[0107] As shown in Figures 4, 9 to 11, in some examples, at least one second air duct 102 is provided between two adjacent first air ducts 101 along the circumference of the pot body 200.

[0108] In some embodiments, at least one second air duct 102 may be provided between two adjacent first air ducts 101 along the circumference of the pot body 200. Based on the aforementioned arrangement, at least one adjacent second air duct 102 may exist on both sides of each first air duct 101 along the circumference of the pot body 200. On the one hand, this can further reduce the air resistance of the third air duct 103, thereby improving the gas exchange efficiency between the cooking appliance and the external environment, and enhancing the heat dissipation efficiency of the pot body 200. On the other hand, it can also facilitate the flow of gas around the periphery of the pot body 200 after entering the third air duct 103, ensuring the contact area between the airflow and the pot body 200, thereby improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0109] It is understandable that, as shown in Figure 4, in practical applications, a second air duct 102 can be opened between two adjacent first air ducts 101 along the circumference of the pot body 200. Thus, along the circumference of the pot body 200, when the second air duct 102 is the aforementioned outlet channel, each second air duct 102 can simultaneously provide an exhaust path for gas entering the third air duct 103 through the first air ducts 101 on both sides. In some embodiments, when the second air duct 102 is the aforementioned inlet channel, gas entering the third air duct 103 through each second air duct 102 can quickly flow along the circumference of the pot body 200 towards the adjacent first air duct 101. This helps reduce the number of channels opened in the shell portion 100, ensuring the structural strength of the shell portion 100 and reducing the probability of damage to the shell portion 100. In some embodiments, as shown in Figures 10 and 11, in practical applications, two or more second air ducts 102 can be opened between two adjacent first air ducts 101 along the circumference of the pot body 200. This increases the air intake or exhaust area of ​​the shell section 100, thereby improving the gas exchange efficiency between the cooking appliance and the external environment. It also improves the stability of the gas flow field within the third air duct 103, reducing the risk of airflow turbulence within the third air duct 103, thus providing a reliable guarantee for the heat dissipation and pressure reduction effect of the pot body section 200.

[0110] As shown in Figure 4, in some examples, along the circumference of the pot body 200, the interval angle α between adjacent first air ducts 101 and second air ducts 102 is greater than or equal to 10° and less than or equal to 160°.

[0111] In some embodiments, the spacing angle α between the first air duct 101 and the second air duct 102, which are adjacent in the circumferential direction of the pot body 200, is constrained. Based on the aforementioned constraint on the spacing angle α, on the one hand, the distance between the first air duct 101 and the second air duct 102 can be avoided from being too close. This is beneficial to ensure that the gas in the third air duct 103 flows around the periphery of the pot body 200 and to prevent the gas from being quickly discharged after entering the third air duct 103, thereby improving the heat transfer between the gas and the pot body 200 and thus improving the heat dissipation and pressure reduction effect of the pot body 200. On the other hand, it also avoids the distance between the first air duct 101 and the second air duct 102 from being too large. This is beneficial to reduce the flow resistance of the gas in the third air duct 103 and increase the flow velocity of the gas in the third air duct 103, thereby further improving the gas exchange efficiency between the cooking appliance and the external environment. This can improve the heat dissipation and pressure reduction efficiency of the pot body 200 and provide favorable conditions for the rapid pressure relief of the cooking appliance after cooking.

[0112] It is understandable that, as shown in Figure 4, the aforementioned interval angle α is the angle between the center position of the first air duct 101 and the center position of the second air duct 102 along the circumference of the pot body 200.

[0113] It is understood that the aforementioned interval angle α can be, but is not limited to, 10°, 50°, 60°, 90°, 157.5°, etc. It should be noted that in practical applications, the aforementioned interval angle α can be selected in conjunction with the capacity of the pot body 200. The larger the capacity of the pot body 200, the more and larger the food that can be cooked in practical applications, and the higher the heat dissipation requirement. Therefore, a relatively smaller interval angle α can be selected to ensure efficient heat dissipation and pressure reduction. Conversely, the smaller the capacity of the pot body 200, the lower the heat dissipation requirement. Therefore, a relatively larger interval angle α can be selected to ensure effective heat dissipation and pressure reduction. In some embodiments, when the capacity of the pot body 200 is less than 5L, the aforementioned interval angle α can be set to be greater than or equal to 10° and less than or equal to 157.5°; when the capacity of the pot body 200 is greater than or equal to 5L, the aforementioned interval angle α can be set to be greater than 10° and less than or equal to 90°.

[0114] As shown in Figures 1 to 3 and Figures 5 to 8, in some examples, the housing portion 100 includes: a first housing 110. The first housing 110 has a groove-shaped structure. A first air duct 101 includes a first ventilation hole 1011 formed in the first housing 110. A second air duct 102 includes a second ventilation hole 1021 formed in the first housing 110. A second housing 120 is disposed within the first housing 110. The second housing 120 has a groove-shaped structure. The first air duct 101 further includes a third ventilation hole 1013 formed in the second housing 120. The second air duct 102 further includes a fourth ventilation hole 1023 formed in the second housing 120. A pot body portion 200 is disposed within the second housing 120. An air supply portion 300 is disposed between the first housing 110 and the second housing 120 and is arranged corresponding to the third ventilation hole 1013.

[0115] In some embodiments, the aforementioned housing portion 100 may include a first housing 110 and a second housing 120. Both the first housing 110 and the second housing 120 may be of a groove-shaped structure. Accordingly, the second housing 120 is disposed within the first housing 110. The aforementioned pot body portion 200 is disposed within the second housing 120. The aforementioned third air duct 103 is formed between the second housing 120 and the pot body portion 200. In some embodiments, the aforementioned second housing 120 may be used as the outer pot of a cooking utensil. The pot body portion 200 may be used as the inner pot of a cooking utensil. The first housing 110 may be used as the outer shell of a cooking utensil.

[0116] The first housing 110 has a first ventilation hole 1011 and a second ventilation hole 1021. 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. One end of the first air duct 101 is connected to the third air duct 103 and is 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. One end of the second air duct 102 is connected to the aforementioned third air duct 103 and is located at the aforementioned fourth ventilation hole 1023. When the air supply unit 300 is in operation, 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.

[0117] The aforementioned air supply unit 300 can be disposed between the first housing 110 and the second housing 120 and corresponding to the third ventilation hole 1013. When the air supply unit 300 supplies air from the first air duct 101 to the third air duct 103, during operation, 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. Conversely, when the air supply unit 300 supplies air from the third air duct 103 to the first air duct 101, during operation, 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. Based on the aforementioned arrangement, it is also beneficial to improve the utilization rate of the internal space of the housing 100, thereby enhancing the structural compactness and miniaturization level of the cooking appliance.

[0118] It is understood that the first vent 1011 and the third vent 1013 can be directly connected; in some embodiments, a first gas channel communicating with the first vent 1011 and the third vent 1013 can also be formed between the first housing 110 and the second housing 120, so that the first vent 1011 and the third vent 1013 are indirectly connected. Accordingly, the first air duct 101 also includes the aforementioned first gas channel. In some embodiments, the aforementioned first gas channel may be, but is not limited to, the mounting 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 mounting space. It is understood that the aforementioned mounting space can be used to install some components of the cooking appliance, such as the electronic control board, the aforementioned air supply unit 300, etc. In some embodiments, the second vent 1021 and the fourth vent 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 vent 1021 and the fourth vent 1023, so that the second vent 1021 and the fourth vent 1023 are indirectly connected. Accordingly, the second air duct 102 also includes the aforementioned second gas channel. In some embodiments, the aforementioned second gas channel may be, but is not limited to, a circumferential gap between the peripheral wall of the first housing 110 and the peripheral wall of the second housing 120. The first vent 1011 and the third vent 1013 are connected through the aforementioned circumferential gap.

[0119] As shown in Figures 1 to 3 and Figures 5 to 8, in some examples, at least one of the third ventilation hole 1013 and the fourth ventilation hole 1023 is formed on the peripheral wall of the second housing 120; and / or at least one of the first ventilation hole 1011 and the second ventilation hole 1021 is formed on the peripheral wall of the first housing 110; and / or at least one of the first ventilation hole 1011 and the second ventilation hole 1021 is formed on the bottom wall of the first housing 110.

[0120] In some embodiments, at least one of the aforementioned third ventilation hole 1013 and the aforementioned fourth ventilation hole 1023 may be provided on the peripheral wall of the aforementioned second housing 120, so that gas can enter or exit the third air duct 103 through the peripheral wall of the second housing 120, thereby helping to reduce the resistance of gas when entering or exiting the third air duct 103, and further helping to reduce airflow loss along the way. This provides further assurance for improving the heat dissipation and pressure reduction efficiency of the pot body 200, and also helps to reduce the energy consumption of the air supply unit 300.

[0121] It is understandable that when at least one of the third ventilation hole 1013 and the fourth ventilation hole 1023 is located on the peripheral wall of the second housing 120 and the other is located on the bottom wall of the first housing 110, the height difference between the third ventilation hole 1013 and the fourth ventilation hole 1023 can be further utilized to generate a velocity component of the gas in the third air duct 103 along the height direction of the pot body 200. This extends the flow path of the gas in the third air duct 103, increases the contact area between the airflow and the pot body 200, and helps improve the heat dissipation effect in the bottom area of ​​the pot body 200.

[0122] It is understandable that when both the third ventilation hole 1013 and the fourth ventilation hole 1023 are opened on the peripheral wall of the second shell 120, the flow resistance when gas enters and exits the third air duct 103 can be further reduced, and it is more conducive to promoting the flow of gas around the periphery of the pot body 200 in the third air duct 103.

[0123] In some embodiments, at least one of the first ventilation hole 1011 and the second ventilation hole 1021 may be provided on the peripheral wall of the first housing 110, so that gas can enter or exit the cooking appliance through the peripheral wall of the first housing 110, thereby reducing the obstruction of the cooking appliance when it is taking in or taking out air, and improving the air intake efficiency of the cooking appliance when it is dissipating heat and reducing pressure, which is beneficial to ensuring the heat dissipation and pressure reduction effect of the pot body 200.

[0124] It is understandable that when both the first ventilation hole 1011 and the second ventilation hole 1021 are opened on the peripheral wall of the first housing 110, the obstruction of the cooking appliance during air intake or exhaust can be further reduced, thereby improving the air intake efficiency of the cooking appliance during heat dissipation and pressure reduction.

[0125] In some embodiments, at least one of the first ventilation hole 1011 and the second ventilation hole 1021 can be formed on the bottom wall of the first housing 110, allowing gas to enter or exit the cooking appliance through the bottom wall of the first housing 110, thereby reducing the impact of the openings on the aesthetics of the cooking appliance. The air inlet and outlet positions of the cooking appliance can also be relatively concealed, which helps prevent the cooking appliance from blowing away external objects when dissipating heat and reducing pressure, thus improving the ease of use of the cooking appliance.

[0126] It is understandable that when both the first ventilation hole 1011 and the second ventilation hole 1021 are located on the bottom wall of the first housing 110, the aesthetics and ease of use of the product can be further improved.

[0127] It is understood that the aforementioned ventilation openings can be installed in various locations simultaneously, or one or more of them can be used. The selection can be based on actual needs, and no further restrictions are imposed here.

[0128] As shown in Figure 5, in some examples, the first ventilation hole 1011 and the third ventilation hole 1013 of the same first air duct 101 have the same conduction direction; and / or the second ventilation hole 1021 and the fourth ventilation hole 1023 of the same second air duct 102 have the same conduction direction.

[0129] In some embodiments, 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 be parallel. This helps to reduce the deflection of gas within the first air duct 101, thereby reducing the friction loss of airflow within the first air duct 101 and saving energy consumption of the air supply unit 300. It also helps to improve the gas exchange efficiency between the cooking appliance and the external environment, thereby improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0130] 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.

[0131] In some embodiments, the conduction directions of the second ventilation hole 1021 and the fourth ventilation hole 1023 in the same 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 in the same second air duct 102 are coincident or parallel. This helps to reduce the deflection of gas in the second air duct 102, thereby reducing the friction loss of airflow in the second air duct 102 and saving energy consumption of the air supply unit 300. It also helps to improve the gas exchange efficiency between the cooking appliance and the external environment, thereby improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0132] It is understandable that the first ventilation hole 1011 and the third ventilation hole 1013 of the same first air duct 101 can be configured to have the same conduction direction, and the second ventilation hole 1021 and the fourth ventilation hole 1023 of the same second air duct 102 can also be configured to have the same conduction direction. This can further reduce gas loss when entering and exiting the shell part 100 and improve the gas exchange efficiency between the cooking appliance and the external environment, thereby improving the heat dissipation and pressure reduction efficiency of the pot body part 200.

[0133] In some examples, each 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 the air inlet or outlet of the air supply section 300 covers the plurality of third ventilation holes 1013; and / or each 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.

[0134] In some embodiments, 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, given a fixed overall conduction area of ​​the first air duct 101, the method of dispersing the first ventilation holes 1011 and the third ventilation holes 1013 can avoid creating excessively large and continuous channels on the housing portion 100. This helps to reduce the weakening of the housing portion 100 caused by openings, thereby ensuring the structural reliability of the cooking appliance. It also helps to improve the regularity of the first ventilation holes 1011 and the third ventilation holes 1013, ensuring the aesthetics of the first housing 110 and the second housing 120.

[0135] In some embodiments, the air inlet or outlet of the air supply unit 300 may be configured to cover multiple third ventilation holes 1013. When the air inlet of the air supply unit 300 covers multiple third ventilation holes 1013, the air intake efficiency of the air supply unit 300 can be guaranteed, and the flow rate within the third air duct 103 can be accelerated, thereby saving energy consumption of the air supply unit 300. When the air inlet of the air supply unit 300 covers multiple third ventilation holes 1013, it can be ensured that as much gas discharged from the air supply unit 300 as possible flows into the third air duct 103 through the third ventilation holes 1013, which helps to ensure the output efficiency of the air supply unit 300, saves energy consumption of the air supply unit 300, and provides a guarantee for the heat dissipation and pressure reduction efficiency of the pot body 200.

[0136] It is understandable that when there is more than one first air duct 101, based on the aforementioned arrangement of this technical solution, when the air supply unit 300 is operating, gas can flow through the first air duct 101 at different circumferential positions. This facilitates the connection of the first air duct 101 to the third air duct 103 through the third ventilation holes 1013 at different circumferential positions. This helps the gas to flow around the periphery of the pot body 200 within the third air duct 103. This ensures uniform heat dissipation around the pot body 200 and further improves the heat dissipation efficiency of the pot body 200.

[0137] 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., which can be set according to actual needs, and no further restrictions are imposed here.

[0138] In some embodiments, each 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 configuration, on the one hand, when the air supply unit 300 is running, the gas can flow through the second air duct 102 at different circumferential positions; and it is convenient for the second air duct 102 to connect with the third air duct 103 through the fourth ventilation hole 1023 at different circumferential positions, which helps the gas to form a flow around the pot body 200 in the third air duct 103, so as to ensure the uniformity of heat dissipation in the circumferential direction of the pot body 200 and further improve the heat dissipation efficiency of the pot body 200; on the other hand, when the total conduction area of ​​the second air duct 102 is constant, the second ventilation hole 1021 and the fourth ventilation hole 1023 can be opened in a dispersed manner to avoid opening excessively large and continuous channels on the shell part 100, which helps to reduce the weakening of the shell part 100 caused by the opening, so as to ensure the structural reliability of the cooking appliance; it also helps to improve the regularity of the second ventilation hole 1021 and the fourth ventilation hole 1023, so as to ensure the aesthetics of the first shell 110 and the second shell 120.

[0139] 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.

[0140] As shown in Figures 1 and 8, in some examples, the cooking appliance further includes a panel 400 disposed on the peripheral wall of the first housing 110. 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.

[0141] In some embodiments, the cooking appliance may further include a panel 400 disposed on the peripheral wall of the first housing 110, thereby further improving the aesthetics of the cooking appliance. Along the circumference of the pot body 200, both the first air duct 101 and the second air duct 102 are spaced apart from the panel 400, thereby reducing the impact of the panel 400 on the airflow into and out of the cooking appliance, ensuring efficient gas exchange between the cooking appliance and the external environment. This prevents the panel 400 from contacting the high-temperature gases emitted by the cooking appliance, thus extending the service life of the panel 400.

[0142] It is understood that the aforementioned panel 400 may include a panel 400 body and a button assembly. The panel 400 body is disposed on the first housing 110, and the button assembly is disposed on the panel 400 body to allow the user to operate the cooking appliance via the button assembly. The panel 400 may also include a display assembly disposed on the aforementioned panel 400 body to display the operating information of the cooking appliance via the display assembly.

[0143] As shown in Figures 2 and 7, in some examples, the air supply unit 300 includes: a flow guiding structure 310 disposed on the housing part 100, the flow guiding structure 310 forming a flow guiding channel 301, the flow guiding channel 301 communicating with the third ventilation hole 1013; and a fan 320 disposed on the flow guiding structure 310, the flow guiding channel 301 being located between the fan 320 and the third ventilation hole 1013, the third ventilation hole 1013 facing the periphery of the pot body part 200.

[0144] In some embodiments, the air supply unit 300 may include a flow guiding structure 310 and a fan 320. The flow guiding structure 310 is disposed on the housing portion 100 and forms a flow guiding channel 301. The flow guiding channel 301 is connected to the aforementioned third ventilation hole 1013. The fan 320 is disposed on the flow guiding structure 310 and is located on the side of the aforementioned flow guiding channel 301 away from the third ventilation hole 1013. Therefore, the fan 320 can be connected to the third ventilation hole 1013 through the flow guiding channel 301. When the air inlet end of the fan 320 faces the flow guiding channel 301, the air intake efficiency of the air supply unit 300 can be guaranteed, thereby increasing the flow velocity in the third air duct 103 and saving energy consumption of the air supply unit 300. With the air outlet of the air supply unit 300 facing the guide channel 301, it can be ensured that the gas discharged from the air supply unit 300 flows into the third air duct 103 through the third ventilation hole 1013, preventing gas from being lost to other parts. This helps to ensure the output efficiency of the air supply unit 300 and saves energy consumption. Therefore, it can guarantee the heat dissipation and pressure reduction efficiency of the pot body 200.

[0145] In some feasible examples, 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, and the third ventilation hole 1013 can be oriented towards the periphery of the pot body 200. Based on the aforementioned arrangement, the guide channel 301 can be gradually expanded circumferentially towards the pot body 200 along the direction close to the third air duct 103, so as to facilitate the gas to flow directly around the circumference of the pot body 200 after flowing out of the guide channel 301. Alternatively, the gas in the third air duct 103 can be made to form a tendency to flow around the pot body 200 before flowing into the guide channel 301, so as to further increase the contact area between the airflow and the pot body 200, thereby improving the heat dissipation and pressure reduction efficiency of the pot body 200. It can also 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 friction loss of the airflow.

[0146] In some examples, fan 320 is either an axial fan 320 or a centrifugal fan 320.

[0147] In some embodiments, the aforementioned fan 320 may be an axial flow fan 320. This is beneficial for increasing the output flow rate of the air supply section 300, thereby improving the heat transfer efficiency between the airflow and the pot body section 200, so as to facilitate rapid heat dissipation and pressure reduction of the pot body section 200.

[0148] In some embodiments, the aforementioned fan 320 can be a centrifugal fan 320. This is beneficial for increasing the output pressure of the air supply section 300. It is also beneficial for reducing the impact of duct resistance on gas flow efficiency. Furthermore, it provides a more reliable guarantee for the heat dissipation and pressure reduction effect of the pot body section 200.

[0149] As shown in Figure 3, in some examples, the cooking appliance also includes a heating element 500 for heating the pot body 200.

[0150] In some embodiments, the cooking appliance may further include a heating element 500. Based on the foregoing configuration, the cooking appliance can utilize the heating element 500 to provide heat to the pot body 200 during the cooking process to achieve the cooking of the food.

[0151] 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.

[0152] In some embodiments, the cooking appliance may further include a lid and a pressure relief valve. The lid is used to cover or open the opening of the pot body 200. During cooking, the lid can be used to cover the opening to ensure stable pressure inside the pot body 200. The pressure relief valve is disposed on the lid. When the lid covers the opening, the pressure relief valve is connected to the interior 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 opening.

[0153] It is understandable that the aforementioned pot opening is also the opening of the pot body 200.

[0154] Understandably, when the cooking appliance is used as an electric pressure cooker, the air supply unit 300 can be used first to dissipate heat and reduce pressure in the pot body 200 after cooking. Once the internal pressure in the pot body 200 has decreased to a certain level, the pressure relief valve can be opened to release the residual pressure. This helps reduce noise from the pressure relief valve during pressure release, avoiding user discomfort caused by excessive noise and improving the user experience.

[0155] Understandably, when the cooking appliance is used as an electric pressure cooker, the air supply unit 300 can be used only to dissipate heat and reduce pressure in the pot body 200 after cooking, lowering the internal pressure of the pot body 200 to the external ambient pressure. This avoids the need for the user to use the pressure relief valve and further reduces noise generated during pressure relief.

[0156] As shown in Figures 12 to 23, 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, 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. 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.

[0157] The cooking appliance provided in this embodiment includes a housing portion 100, a pot body portion 200, and an air supply portion 300. The housing portion 100 has a first air duct 101 and a second air duct 102, both located on the peripheral wall of the housing portion 100. The pot body portion 200 is disposed inside the housing portion 100, and a third air duct 103 is formed between the pot body portion 200 and the housing 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 housing portion 100 and located within the first air duct 101, with one end of the first air duct 101 communicating with the third air duct 103 located between the air supply portion 300's guide channel 301 and the third air duct 103. Based on the above configuration, the cooking appliance provided in this embodiment can utilize the aforementioned air ducts to provide space for gas flow. In practical applications, after cooking, the cooking appliance can power the airflow through the air supply unit 300 to flow through the aforementioned air ducts. As the air flows along the third air duct 103, it exchanges heat with the pot body 200. This improves the heat dissipation efficiency of the pot body 200, reducing the temperature of the pot body 200 and the food inside. This makes it easier for users to eat after cooking and reduces the risk of burns.

[0158] 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. Both the aforementioned shell portion 100 and the aforementioned pot body portion 200 can be groove-shaped structures, that is, both the shell portion 100 and the pot body portion 200 can be hollow internally and open at one end. The internal space of the pot body portion 200 can serve as a cooking space. The internal space of the shell portion 100 can serve 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 the open end of the shell portion 100. The peripheral wall of the aforementioned shell portion 100 is also the portion between the open end and the bottom wall of the shell portion 100. In some embodiments, the bottom wall of the pot body portion 200 is also the side opposite the open end of the pot body portion 200. The peripheral wall of the pot body portion 200 is also the portion 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.

[0159] 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. This helps to reduce the noise generated when the cooking appliance releases pressure. It can reduce the safety burden on the user during operation and improve the user experience of the product.

[0160] It should be noted that the aforementioned housing portion 100 has a first air duct 101 and a second air duct 102 on its peripheral wall. This means that one end of the first air duct 101, which connects 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, which connects 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 can be located on the bottom wall or the peripheral wall of the housing portion 100.

[0161] It is understood that both the first air duct 101 and the second air duct 102 are connected to the third air duct 103, meaning that the first air duct 101 is connected to the second air duct 102 via 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. Therefore, one of the first air duct 101 and the second air duct 102 can serve as an inlet channel for gas from the external environment to flow into the housing 100. Correspondingly, the other can serve as an outlet channel for gas to flow out of the housing 100, depending on the air supply direction of the air supply unit 300. In some embodiments, as shown in FIG23, 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 into 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. In some embodiments, when the air supply unit 300 supplies air from the third air duct 103 to the first air duct 101, the air supply unit 300 can draw in gas from the third air duct 103 during operation and discharge it from the shell part 100 through the first air duct 101, so as to increase the gas flow rate around the pot body 200 and accelerate the heat dissipation of the pot body 200. Accordingly, gas from the external environment can enter the shell section 100 through the second air duct 102 and flow to the third air duct 103 to replenish the third air duct 103 with lower-temperature gas, ensuring the heat dissipation efficiency of the pot body section 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 the dashed curve with arrows in Figure 23 is used to schematically represent the direction of gas flow.

[0162] 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 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; it can increase the distribution range of the air duct inside the shell part 100, so as to increase the contact area between the airflow and the pot body 200, thereby improving the cooling and depressurization efficiency of the pot body 200.

[0163] It is understood that the cooking appliance provided in this disclosure, by placing the air supply unit 300 within the first air duct 101, creates a certain distance between the air supply unit 300 and the pot body 200. This helps reduce the impact of heat from the pot body 200 on the air supply unit 300. Therefore, the risk of overheating of the air supply unit 300 can be reduced, thereby reducing the probability of damage to the air supply unit 300.

[0164] It should be noted that in traditional techniques, some cooking appliances typically have air ducts in the outer pot, with a fan at one end of the duct. The fan directs gas into the annular gap between the outer and inner pots, thus cooling the inner pot. To prevent the fan from contacting the outer pot during operation, a gap is often left between the fan's outlet side and the outer pot. This gap allows some of the gas output by the fan to escape, failing to flow into the annular gap through the air duct. Consequently, this results in significant airflow loss from the fan, leading to low efficiency in air-cooling and pressure reduction.

[0165] 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 when the air supply unit 300 supplies air from the first air duct 101 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. It also prevents airflow from escaping within the first air duct 101. Therefore, it is beneficial to improve the flow-promoting effect of the air supply unit 300 on the gas flow within the third air duct 103, thereby improving the heat dissipation efficiency of the airflow on the pot body 200. In some embodiments, 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 one end of the third air duct 103, can flow into the guide channel 301, allowing it to more quickly converge into the air supply unit 300, thereby improving the suction efficiency of the air supply unit 300 on the gas in the third air duct 103. This further increases the gas flow rate within the third air duct 103, thereby 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. This improves the operating efficiency of the air supply unit 300, facilitating more efficient use of airflow to dissipate heat from the pot body 200, thus saving energy consumption of the air supply unit 300.

[0166] As shown in Figures 12 to 15 and Figures 20 to 22, in some examples, the housing portion 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 includes a third ventilation hole 1013 opened in the second housing 120; and the second air duct 102 further includes a fourth ventilation hole 1023 opened in the second housing 120; wherein, the pot body portion 200 is disposed within the second housing 120; the air supply portion 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.

[0167] In some embodiments, the aforementioned housing portion 100 may include a first housing 110 and a second housing 120. Both the first housing 110 and the second housing 120 may be of a groove-shaped structure. Accordingly, the second housing 120 is disposed within the first housing 110. The aforementioned pot body portion 200 is disposed within the second housing 120. The aforementioned third air duct 103 is formed between the second housing 120 and the pot body portion 200. In some embodiments, the aforementioned second housing 120 may be used as the outer pot of a cooking utensil. The pot body portion 200 may be used as the inner pot of a cooking utensil. The first housing 110 may be used as the outer shell of a cooking utensil.

[0168] The first housing 110 has a first ventilation hole 1011 and a second ventilation hole 1021. 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 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 located at the aforementioned fourth ventilation hole 1023. When the air supply unit 300 is in operation, 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.

[0169] 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 within the aforementioned installation space. Therefore, 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 operating, 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 operating, 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. Based on the aforementioned configuration, it is also beneficial to improve the utilization rate of the internal space of the housing 100, as well as to enhance the structural compactness and miniaturization of the cooking appliance. It is understood that the aforementioned first air duct 101 also includes the aforementioned installation space.

[0170] 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.

[0171] 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. Accordingly, the second air duct 102 also includes the aforementioned second gas channel. In some embodiments, the aforementioned first gas channel may be, but is not limited to, a 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.

[0172] As shown in Figures 13, 16 to 18, 21 and 22, 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.

[0173] In some embodiments, 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. Therefore, 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, and the flow velocity in the third air duct 103 can be accelerated to save 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. This prevents gas from being lost to other parts, which helps to ensure the output efficiency of the air supply unit 300 and save energy consumption of the air supply unit 300. Therefore, the heat dissipation and pressure reduction efficiency of the pot body 200 can be guaranteed.

[0174] As shown in Figure 23, in some examples, the length of the guide channel 301 in the circumferential direction of the pot body 200 increases along the direction from the fan 320 to the third ventilation hole 1013.

[0175] In some embodiments, 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 circumferentially towards the pot body 200 along the direction close to the third air duct 103, thereby facilitating the direct circumferential flow of gas around the pot body 200 after flowing out of the guide channel 301, or causing the gas in the third air duct 103 to tend to flow around the pot body 200 before flowing into the guide channel 301. This is beneficial for further increasing the contact area between the airflow and the pot body 200, thereby improving the heat dissipation and pressure reduction efficiency of the pot body 200. It can also 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.

[0176] 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.

[0177] In some embodiments, 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. In some embodiments, 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 suction efficiency of the air supply in 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.

[0178] 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.

[0179] As shown in Figures 16 to 19, 21 and 22, in some examples, the flow guiding structure 310 includes: a support member 311 with an installation groove and a vent communicating with the installation groove, a fan 320 disposed in the installation groove, and the air inlet or outlet side of the fan 320 facing the vent; a flow guiding member 312 disposed on the support member 311 and located between the support member 311 and the second housing 120, the flow guiding member 312 having a flow guiding channel 301, and the vent communicating with the flow guiding channel 301; and a connector 313 disposed on the support member 311 and connected to the first housing 110.

[0180] In some embodiments, the aforementioned airflow guiding structure 310 may include a support member 311, an airflow guiding member 312, and a connecting member 313. Both the connecting member 313 and the airflow guiding member 312 are disposed on the support member 311. The support member 311 is used to mount the aforementioned fan 320, and the connecting member 313 is connected to the first housing 110. The air supply section 300 can be disposed on the housing section 100 via the connecting member 313, thereby ensuring the positional stability of the air supply section 300. The airflow guiding member 312 is located between the support member 311 and the second housing 120, and forms the aforementioned airflow guiding channel 301. The air inlet or outlet side of the fan 320 is connected to the airflow guiding channel 301 through a vent on the support member 311, thereby facilitating the connection of the gas passage between the fan 320 and the third ventilation hole 1013, and facilitating the use of the fan 320 to drive the gas flow within the third air duct 103 to dissipate heat and reduce pressure in the pot body section 200.

[0181] 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.

[0182] As shown in Figures 16 to 18, 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.

[0183] In some embodiments, the aforementioned guide member 312 can be a tubular structure. One end of the guide member 312 can be positioned around the vent, and the other end can be positioned towards the third vent 1013. Correspondingly, the aforementioned guide channel 301 is formed inside the guide member 312. Based on the aforementioned configuration, while ensuring the guiding function of the guide channel 301 for 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.

[0184] It is understandable that, as shown in Figures 16 to 18, 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.

[0185] As shown in Figures 19 to 22, in some examples, the flow guide 312 has a plate-like structure. The flow guide 312 extends circumferentially along the second housing 120. The flow channel 301 is formed on the side of the flow guide 312 facing the third ventilation hole 1013.

[0186] In some embodiments, 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 formed 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 tendency around the second housing 120 circumferentially, thereby making the airflow direction in the guide channel 301 more adapted 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. It facilitates the airflow to generate a circumferential flow around the pot body 200 within the third air duct 103. It helps to increase the contact area between the airflow and the pot body 200, thereby further improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0187] It is understandable that, as shown in Figures 19 to 22, when the guide member 312 has a plate-like 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 over the third ventilation hole 1013, thereby helping to ensure the driving efficiency of the air supply unit 300. It also helps to expand the distribution range length of the third ventilation hole 1013 along the circumference of the second housing 120, thereby promoting gas flow at different circumferential positions within the third air duct 103. Furthermore, it helps to further expand the contact area between the airflow and the pot body 200, improving the heat transfer efficiency between the airflow and the pot body 200, thus providing a more reliable guarantee for improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0188] It is understandable that, as shown in Figure 19, 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.

[0189] As shown in Figures 13 to 15 and Figures 20 to 22, 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.

[0190] In some embodiments, 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 constant, by dispersing the first ventilation holes 1011 and the third ventilation holes 1013, it is possible to avoid opening excessively large and continuous channels on the housing portion 100, which helps to reduce the weakening of the housing portion 100 caused by opening holes, thereby ensuring the structural reliability of the cooking appliance. It also helps to improve the regularity of the first ventilation holes 1011 and the third ventilation holes 1013, thereby ensuring the aesthetics of the first housing 110 and the second housing 120.

[0191] 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., which can be set according to actual needs, and no further restrictions are imposed here.

[0192] In some embodiments, 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, given a fixed overall conduction area of ​​the second air duct 102, the second ventilation holes 1021 and the fourth ventilation holes 1023 can be distributed to avoid creating excessively large and continuous channels on the housing portion 100. This helps reduce the weakening of the housing portion 100 caused by openings, thereby ensuring the structural reliability of the cooking appliance. It also helps improve the regularity of the second ventilation holes 1021 and the fourth ventilation holes 1023, thereby ensuring the aesthetics of the first housing 110 and the second housing 120.

[0193] 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., which can be set according to actual needs, and no further restrictions are imposed here.

[0194] As shown in Figure 14, 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.

[0195] In some embodiments, 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 be parallel. This helps to reduce gas deflection within the first air duct 101 and reduce airflow loss along the path within the first air duct 101, thereby saving energy consumption of the air supply unit 300. It also helps to improve the gas exchange efficiency between the cooking appliance and the external environment, thereby improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0196] 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.

[0197] In some embodiments, 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 be parallel. This helps to reduce gas deflection within the second air duct 102 and reduce airflow loss along the path within the second air duct 102, thereby saving energy consumption of the air supply unit 300. It also helps to improve the gas exchange efficiency between the cooking appliance and the external environment, thereby improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0198] 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.

[0199] It is understandable that the first ventilation hole 1011 and the third ventilation hole 1013 of the first air duct 101 can have the same direction of conduction, and the second ventilation hole 1021 and the fourth ventilation hole 1023 of the second air duct 102 can have the same direction of conduction. This can further reduce gas loss when entering and exiting the shell part 100, and improve the gas exchange efficiency between the cooking appliance and the external environment, thereby improving the heat dissipation and pressure reduction efficiency of the pot body part 200.

[0200] As shown in Figure 12, in some examples, at least two first air ducts 101 are spaced apart along the circumference of the pot body portion 200. Each first air duct 101 is provided with an air supply portion 300.

[0201] In some embodiments, at least two first air ducts 101 are spaced apart along the circumference of the pot body 200. 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 increased, which is beneficial to increasing the contact area and heat transfer efficiency between the airflow and the pot body 200. Based on the circumferential positional differences between the multiple first air ducts 101, it is beneficial to promote the flow of gas around the pot body 200 within 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 gas driving performance of the cooking appliance and enhance the gas exchange efficiency between the cooking appliance and the external environment, thereby reducing the limitation of airflow loss along the path on heat dissipation and pressure reduction efficiency, and further improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0202] It should be noted that, as shown in Figures 21 and 22, the air supply direction 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. This helps 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, thereby improving the heat dissipation effect of the gas on the pot body 200. In some embodiments, the air supply direction of each air supply unit 300 can be opposite. That is, some air supply units 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. This helps to accelerate the air intake and exhaust efficiency in the air supply units 300. Based on the circumferential positional differences between the various air supply sections 300, it is more conducive to the flow of gas around the periphery of the pot body section 200 within the third air duct 103, thereby increasing the heat transfer efficiency and heat dissipation effect between the airflow and the pot body section 200.

[0203] As shown in Figure 23, 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.

[0204] In some embodiments, 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. In some embodiments, 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 have different positions in the circumferential direction of the pot body portion 200. Based on the aforementioned arrangement, when the air supply unit 300 is running, the circumferential positional difference between the first air ducts 101 and the second air ducts 102 can be used to promote gas flow around the periphery of the pot body portion 200 after entering the third air duct 103, reducing airflow resistance and improving the smoothness of airflow within the third air duct 103, thereby facilitating an increase in gas flow rate within each air duct. It can increase the distribution range of the air duct inside the shell part 100, so as to increase the contact area between the airflow and the pot body part 200, thereby improving the cooling and pressure reduction efficiency of the pot body part 200.

[0205] 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 in the circumferential direction. Therefore, when the first air duct 101 serves as the aforementioned inlet channel, it can be ensured that the gas enters the third air duct 103 and forms a diversion; in some embodiments, when the second air duct 102 serves as the aforementioned inlet channel, it is ensured that the gas in the external environment enters the third air duct 103 at different positions in the circumferential direction of the pot body 200 and converges to the first air duct 101. Therefore, the contact area between the pot body 200 and the gas in the third air duct 103 can be guaranteed, thereby reducing the temperature difference in the circumferential direction of the pot body 200. The conduction area between the third air duct 103 and the external environment can be increased to improve 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. 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, thereby reducing the machining difficulty of the shell part 100.

[0206] As shown in Figure 14, in some examples, the cooking appliance also includes a heating element 500 for heating the pot body 200.

[0207] In some embodiments, the cooking appliance may further include a heating element 500. Based on the foregoing configuration, the cooking appliance can utilize the heating element 500 to provide heat to the pot body 200 during the cooking process to achieve the cooking of the food.

[0208] 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.

[0209] In some embodiments, the cooking appliance may further include a lid and a pressure relief valve. The lid is used to cover or open the opening of the pot body 200. During cooking, the lid can be used to cover the opening to ensure stable pressure inside the pot body 200. The pressure relief valve is disposed on the lid and is connected to the interior of the pot body 200 when the lid covers the opening. After cooking is completed, the internal pressure of the pot body 200 can be released by opening the pressure relief valve, allowing the lid to open the opening.

[0210] It is understandable that the aforementioned pot opening is also the opening of the pot body 200.

[0211] Understandably, in practical applications, after cooking, the air supply unit 300 can be used first to dissipate heat and reduce pressure in the pot body 200. Once the internal pressure of the pot body 200 has decreased to a certain level, the pressure relief valve can be opened to release the residual pressure within the pot body 200. This helps reduce the noise of the pressure relief valve when releasing pressure, avoiding user discomfort caused by excessive noise. This improves the user experience of the product.

[0212] Understandably, in practical applications, after cooking, the air supply unit 300 can be used only to dissipate heat and reduce pressure in the pot body 200, lowering the internal pressure of the pot body 200 to the external ambient pressure. This avoids the need for the user to use a pressure relief valve, further reducing noise generated by the cooking appliance during pressure relief.

[0213] As shown in Figure 12, 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.

[0214] In some embodiments, the cooking appliance may further include a panel 400 disposed on the peripheral wall of the first housing 110 to further improve the aesthetics of the cooking appliance. Along the circumference of the pot body 200, both the first air duct 101 and the second air duct 102 are spaced apart from the panel 400 to reduce the impact of the panel 400 on the airflow into and out of the cooking appliance, thereby ensuring efficient gas exchange between the cooking appliance and the external environment. This prevents the panel 400 from contacting the high-temperature gases emitted by the cooking appliance, thus extending the service life of the panel 400.

[0215] 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.
