The capacity of the pot liner 21 is generally below 6L, for example, the capacity of the pot liner 21 can be 2L or 4L, etc. The pot liner 21 has a pot liner opening for taking and placing food materials, and an inner space of the pot liner 21 forms a cooking cavity 22 for holding and heating food materials. The cover body 10 can be pivotably connected to the pot body 20 by a pivot shaft for covering the pot body 20.

[0186] The cooking utensil 100 has a heating device 28. The heating device 28 is generally arranged at the bottom of the pot body 20, below the pot liner 21. The heating device 28 is used to heat the pot liner 21 and the food materials therein, thereby realizing the cooking function. The heating device 28, for example, can be configured in the form of a heating disc, an electromagnetic heating coil, etc.

[0187] The cooking utensil 100 has a top temperature sensor 17A, which is generally arranged on the cover body 10 and is used to detect the top temperature of the cooking cavity 22. A bottom temperature sensor 17B is also arranged in the pot body 20 and is used to detect the bottom temperature of the cooking cavity 22. The bottom temperature sensor 17B, for example, is in contact with the bottom wall of the pot liner 21.

[0188] In addition, the cooking utensil 100 also includes a control device (not shown), which is used to realize the cooking control of the cooking utensil 100. The control device, for example, can be a micro control unit (MCU). The control device is electrically connected with the heating device 28 and the temperature sensors, so that the control device can control the heating device 28 to work according to the detection values of the temperature sensors.

[0189] It should be noted that, in the present application, the directional terms "upper" and "lower" are determined based on the cooking utensil 100 which is placed upright and the cover body 10 is in a closed state.

[0190] It should be noted that, although the partial structure of the cooking utensil 100 is described schematically at this time, these enumerations are only exemplary and cannot be regarded as a limitation on the structure of the cooking utensil 100 of the embodiments of the present application.

[0191] As Figure 3 and Figure 5As shown, the lid 10 includes, for example, a face cover 13, a backing cover 11 and a detachable cover 12. The backing cover 11 forms a skeleton of the lid 10, and various components (e.g. a top temperature sensor 17A) in the lid 10 are mounted on the backing cover 11. The face cover 13 forms an outer shell of the lid 10, and is mounted on the backing cover 11. The detachable cover 12 is detachably connected to the backing cover 11, and is located at a bottom of the lid 10. The detachable cover 12 is used to cover a pot opening of the inner pot 21.

[0192] The cooking process of the cooking appliance 100 includes, for example, a preheating procedure, a water absorption procedure, a boiling procedure, a boiling maintenance procedure, a rice stewing procedure and a temperature maintenance procedure. The preheating procedure is used to preliminarily heat the foodstuff. In the water absorption procedure, the foodstuff is fully absorbed with water to improve the taste. In the boiling procedure, the foodstuff is heated to a temperature close to boiling with a high fire, and then is boiled in the boiling maintenance procedure to substantially cook the foodstuff. In the rice stewing procedure, the residual free water is dried to further cook the foodstuff. In the temperature maintenance procedure, the foodstuff is maintained at a temperature to allow the user to eat the foodstuff.

[0193] To improve the cooking quality, in the water absorption procedure, the cooking cavity 22 is usually pumped to a negative pressure, i.e. the air pressure in the cooking cavity 22 is lower than the ambient air pressure. The negative pressure environment is beneficial to the foodstuff to fully absorb water. In the temperature maintenance procedure, the cooking cavity 22 is also pumped to a negative pressure, and the negative pressure environment is beneficial to the foodstuff to be fresh. To improve the cooking efficiency, in the boiling maintenance procedure, the cooking cavity 22 is blown with cold air, i.e. the ambient air is discharged into the cooking cavity 22 to prevent the foodstuff from overflowing. Thus, in the boiling maintenance procedure, the heating device 28 can maintain a relatively high power to quickly cook the foodstuff.

[0194] To achieve the above functions, referring back to Figure 6 , the cooking appliance 100 further includes an air flow generating device 14 and an air path integrating device 30. The air flow generating device 14, the air path integrating device 30 and the cooking cavity 22 are organically connected to form an air path structure 110 of the cooking appliance 100, which can realize the steam discharge, the negative pressure pumping and the cold air blowing of the cooking cavity 22.

[0195] The air flow generating device 14 is a component for promoting the air flow, e.g. an air pump. The air flow generating device 14 includes an air flow inlet 15 and an air flow outlet 16. When the air flow generating device 14 works, the air flow enters the air flow generating device 14 from the air flow inlet 15, and then is discharged from the air flow outlet 16. The air flow generating device 14 is electrically connected to the control device to work under the control of the control device.

[0196] As shown in Figures 6 to 8As shown, the air path integration device 30 has a device housing 38 enclosing a device internal cavity 39. The device housing 38 can be formed by the outer shells or partial outer shells of the components of the air path integration device 30 in the assembled state. The device housing 38 is provided with a housing opening 55 through which the device internal cavity 39 is in communication with the external environment. The device internal cavity 39 is provided with a first air path 111 (see the red arrow air flow path in the figure), a second air path 112 (see the brown arrow air flow path in the figure), a third air path 113 (see the blue arrow air flow path in the figure), a fourth air path 114 (see the green arrow air flow path in the figure), and a fifth air path 115 (see the purple arrow air flow path in the figure). Each air path, i.e. an air flow channel, can be formed by a pipe, a cavity, an opening, or any structure through which air can pass. In other words, the pipe, the cavity, the opening, or any structure through which the air flow passes is a constituent part of the air path.

[0197] Specifically, the first air path 111 is configured to connect the cooking cavity 22 and the air flow inlet 15, and air flows from the cooking cavity 22 to the air flow inlet 15. The second air path 112 is configured to connect the air flow outlet 16 and the housing opening 55, and air flows from the air flow outlet 16 to the housing opening 55. The third air path 113 is configured to connect the cooking cavity 22 and the housing opening 55, and air flows from the cooking cavity 22 to the housing opening 55. The fourth air path 114 is configured to connect the housing opening 55 and the air flow inlet 15, and air flows from the housing opening 55 to the air flow inlet 15. The fifth air path 115 is configured to connect the air flow outlet 16 and the cooking cavity 22. Thus, by means of the first air path 111 and the second air path 112, the cooking cavity 22 can be subjected to negative pressure when the air flow generating device 14 is in operation. By means of the third air path 113, the cooking cavity 22 can be subjected to steam exhaust. By means of the fourth air path 114 and the fifth air path 115, the cooking cavity 22 can be subjected to air blowing when the air flow generating device 14 is in operation.

[0198] The mode in which the first air path 111 and the second air path 112 are connected is an air extraction mode in which the air path integration device 30 extracts air from the cooking cavity 22. The mode in which the third air path 113 is connected is a steam exhaust mode in which the air path integration device 30 exhausts steam from the cooking cavity 22. The mode in which the fourth air path 114 and the fifth air path 115 are connected is an air injection mode in which the air path integration device 30 injects air into the cooking cavity 22.

[0199] The first air path 111, the second air path 112, the fourth air path 114 and the fifth air path 115 are connected with the air flow generating device 14, and the air flow direction therein is determined by the air flow generating device 14. The first air path 111 and the fourth air path 114 are upstream air paths of the air flow generating device 14. The second air path 112 and the fifth air path 115 are downstream air paths of the air flow generating device 14. The third air path 113 is not connected with the air flow generating device 14, and the air flow direction therein is determined by the air pressure at both ends of the air path. When the food is boiled, a large amount of hot steam is generated in the cooking cavity 22, and the air pressure of the steam is higher than the ambient air pressure, so the air flow flows from the cooking cavity 22 to the housing opening 55.

[0200] It can be seen that the air path integration device 30 is connected with the air flow generating device 14 and the cooking cavity 22, or in other words, the device inner cavity 39 is in communication with the air flow generating device 14 and the cooking cavity 22, and the air path integration device 30 internally integrates the air paths for extracting negative pressure, discharging steam and blowing cold wind for the cooking cavity 22. The integrated design reduces the number of components of the cooking utensil 100 and makes assembly easier.

[0201] Preferably, the air path integration device 30 and the air flow generating device 14 are both arranged in the cover body 10, for example, mounted in the cover 11. As shown in Figure 4 and Figure 5 , the cover 11 is provided with a cover accommodating groove 11A for accommodating the air path integration device 30. The air path integration device 30 is detachably mounted in the cover accommodating groove 11A, for example, so as to facilitate user cleaning. It can be understood that the face cover 13 is provided with an opening at a position corresponding to the cover accommodating groove 11A.

[0202] For example, as shown in Figures 3 to 6 , the cover body 10 is provided with an air outlet passage 18 and an air inlet passage 19. When the cover body 10 covers the pot body 20, the air outlet passage 18 and the air inlet passage 19 are both in communication with the cooking cavity 22. The air path integration device 30 has an exhaust pipe 56, a third air pipe 57, a first air pipe 58 and a second air pipe 59. The exhaust pipe 56, the third air pipe 57, the first air pipe 58 and the second air pipe 59 are all in communication with the device inner cavity 39. When the air path integration device 30 is mounted to the cover body 10, the exhaust pipe 56 is in communication with the air outlet passage 18, and the second air pipe 59 is in communication with the air inlet passage 19, so that the device inner cavity 39 is in communication with the cooking cavity 22. The third air pipe 57 is in communication with the air flow inlet 15. The first air pipe 58 is in communication with the air flow outlet 16. Here, the communication between two components can be that the two components are directly connected, or the two components are connected through a pipeline such as a conduit, an air pipe, etc. The port of the pipeline can also be understood as the interface of the component. For example, the interfaces of the cover body 10 and the air flow generating device 14 for connecting with the air path integration device 30 are both arranged on the bottom wall of the accommodating groove 11A, and the interfaces of the air path integration device 30 are all arranged on the lower surface of the device shell 38, so as to facilitate the connection of the air path structure 110.

[0203] The first and fourth air paths 111, 114 are upstream of the airflow generating device 14 and can share the third vent pipe 57. Specifically, the third vent pipe 57 is connected to both the first and fourth air paths 111, 114. The third vent pipe 57 is also referred to as a tubular connector. The second and fifth air paths 112, 115 are downstream of the airflow generating device 14 and can share the first vent pipe 58. Specifically, the first vent pipe 58 is connected to both the second and fifth air paths 112, 115.

[0204] like Figure 7 and Figure 8 As shown, the internal cavity 39 of the device may include an air blowing cavity 81, a switching cavity 82, an exhaust and extraction cavity 83, a ventilation cavity 84, and an exhaust cavity 85. The housing openings 55 are provided in the walls of the ventilation cavity 84 and the exhaust cavity 85, but not in the walls of the air blowing cavity 81, the switching cavity 82, and the exhaust and extraction cavity 83. Therefore, the ventilation cavity 84 and the exhaust cavity 85 are always connected to the external environment. The exhaust and extraction cavity 83 is connected to both the exhaust pipe 56 and the third ventilation pipe 57, and thus is always connected to the cooking cavity 22 and the air flow inlet 15. The first ventilation pipe 58 is connected to the switching cavity 82, thereby always connecting to the air flow outlet 16. The air blowing cavity 81 is connected to the second ventilation pipe 59, and thus is always connected to the cooking cavity 22.

[0205] The structure of the air path integration device 30 located on the first air path 111 includes, in order along the airflow direction, an exhaust pipe 56, an exhaust chamber 83, and a third vent pipe 57. The structure of the air path integration device 30 located on the second air path 112 includes, in order along the airflow direction, a first vent pipe 58, a switching chamber 82, and an exhaust chamber 85. The switching chamber 82 and the exhaust chamber 85 are adjacent to each other. The structure of the air path integration device 30 located on the third air path 113 includes, in order along the airflow direction, an exhaust pipe 56, an exhaust chamber 83, and a vent chamber 84. The exhaust chamber 83 and the vent chamber 84 are adjacent to each other. The structure of the air path integration device 30 located on the fourth air path 114 includes, in order along the airflow direction, a vent chamber 84, an exhaust chamber 83, and the third vent pipe 57. The structure of the air path integration device 30 located on the fifth air path 115 includes, in order along the airflow direction, a first vent pipe 58, a switching chamber 82, an air blowing chamber 81, and a second vent pipe 59. The switching chamber 82 and the air blowing chamber 81 are adjacent to each other.

[0206] The switching chamber 82 and the blowing chamber 81 are collectively referred to as the combined chamber 86. The combined chamber 86 is used to connect the first vent pipe 58 and the second vent pipe 59. The combined chamber 86 is used to connect the first vent pipe 58 and the cooking chamber 22. The combined chamber 86 is used to connect the airflow outlet 16 and the second vent pipe 59. The combined chamber 86 is used to connect the airflow outlet 16 and the cooking chamber 22.

[0207] To make the gas path integration device 30 compact, components are shared among multiple gas paths. To make the gas path integration device 30 work in order, multiple valve devices are provided in the device inner cavity 39 to control the on-off of the gas paths.

[0208] For example, on the second gas path 112, a third opening 43 is provided on the shared cavity wall 51 (also referred to as the first shared cavity wall 51) between the switching cavity 82 and the exhaust cavity 85. When the third opening 43 is open, the second gas path 112 is on. When the second gas path 112 is on, the gas path downstream of the airflow generation device 14 in the gas path for drawing negative pressure in the cooking cavity 22 is on. When the third opening 43 is closed, the second gas path 112 is off. When the second gas path 112 is off, the gas path downstream of the airflow generation device 14 in the gas path for drawing negative pressure in the cooking cavity 22 is off.

[0209] The second one-way valve 35 in the device inner cavity 39 is used to open and close the third opening 43. When the second one-way valve 35 opens the third opening 43, the second gas path 112 is on, and allows the airflow to flow unidirectionally from the switching cavity 82 to the exhaust cavity 85 (i.e. allows the airflow to flow unidirectionally from the first air duct 58 to the exhaust cavity 85, allows the airflow to flow unidirectionally from the first air duct 58 to the housing opening 55, allows the airflow to flow unidirectionally from the airflow outlet 16 to the exhaust cavity 85, and allows the airflow to flow unidirectionally from the airflow outlet 16 to the housing opening 55). When the second one-way valve 35 is open, the gas path integration device 30 is in the air drawing mode, and an air drawing gas path is formed between the exhaust cavity 83, the third air duct 57, the airflow generation device 14, the first air duct 58, the switching cavity 82, and the exhaust cavity 85. When the second one-way valve 35 closes the third opening 43, the second gas path 112 is off.

[0210] On the fifth gas path 115, a second opening 42 is provided on the shared cavity wall 52 (also referred to as the second shared cavity wall 52) between the switching cavity 82 and the blowing cavity 81. When the second opening 42 is open, the fifth gas path 115 is on. When the fifth gas path 115 is on, the gas path downstream of the airflow generation device 14 in the gas path for blowing cold air into the cooking cavity 22 is on. When the second opening 42 is closed by the fifth one-way valve 37, the fifth gas path 115 is off. When the fifth gas path 115 is off, the gas path downstream of the airflow generation device 14 in the gas path for blowing cold air into the cooking cavity 22 is off.

[0211] The second opening 42 is located on the gas path for connecting the airflow outlet 16 and the cooking cavity 22 in the device inner cavity 39.

[0212] The fifth one-way valve 37 (also known as the floating seal assembly 37 ) in the device's internal cavity 39 is used to open and close the second opening 42. When the fifth one-way valve 37 opens the second opening 42, the fifth air path 115 is open, allowing one-way air flow from the switching chamber 82 to the blowing chamber 81 (i.e., allowing one-way air flow from the first vent pipe 58 to the blowing chamber 81, allowing one-way air flow from the first vent pipe 58 to the second vent pipe 59, allowing one-way air flow from the first vent pipe 58 to the cooking chamber 22, allowing one-way air flow from the air outlet 16 to the blowing chamber 81, allowing one-way air flow from the air outlet 16 to the second vent pipe 59, and allowing one-way air flow from the air outlet 16 to the cooking chamber 22). When the fifth one-way valve 37 closes the second opening 42, the fifth air path 115 is blocked. For example, the floating seal assembly 37 is movable relative to the second opening 42 (i.e., the device's internal cavity 39 or the device housing 38) between a second open position and a second closed position. When the floating seal assembly 37 is in the second open position, it opens the second opening 42, connecting the switching chamber 82 to the blowing chamber 81. A continuous air path is formed between the first vent pipe 58, the switching chamber 82, the blowing chamber 81, and the second vent pipe 59. When the floating seal assembly 37 is in the second closed position, it closes the second opening 42, isolating the switching chamber 82 from the blowing chamber 81. The second opening 42 and the floating seal assembly 37 are both located between the switching chamber 82 and the blowing chamber 81.

[0213] like Figure 7 As shown, the axial direction of the second opening 42 is DA. The floating seal assembly 37 extends through the second opening 42 and is movable in the second opening 42 along the axial direction DA between a second open position and a second closed position. A gap is defined between at least a portion of the floating seal assembly 37 (e.g., the portion of the floating seal assembly 37 that is adapted to move through the second opening 42) and the inner circumferential surface of the second opening 42. When the floating seal assembly 37 is in the second closed position (the position shown in the figure), the floating seal assembly 37 blocks the second opening 42. When the floating seal assembly 37 is in the second open position, the floating seal assembly opens the second opening 42, allowing airflow to flow through the gap between the floating seal assembly 37 and the inner circumferential surface of the second opening 42.

[0214] Further, the cooking appliance 100 is configured to, in the water absorbing process and / or the heat preserving process, make the second air path 112 conductive and the fifth air path 115 blocked; in the boiling maintaining process, make the second air path 112 blocked and the fifth air path 115 conductive. In other words, the cooking appliance 100 is configured to, in the water absorbing process and / or the heat preserving process, make the second one-way valve 35 open the third opening 43 and make the fifth one-way valve 37 close the second opening 42; in the boiling maintaining process, make the second one-way valve 35 close the third opening 43 and make the fifth one-way valve 37 open the second opening 42. Both the second air path 112 and the fifth air path 115 are downstream of the airflow generating device 14 and are used to guide the airflow discharged by the airflow generating device 14. When negative pressure needs to be drawn, the downstream air path for drawing negative pressure is connected to the environment and not connected to the cooking cavity 22; when cold air needs to be blown, the downstream air path for blowing cold air is connected to the cooking cavity 22 and not connected to the environment. Thus, the airflow is orderly and directionally guided to achieve the expected effect. In Figure 7 It can be clearly seen that the downstream air paths (the brown second air path 112 and the purple fifth air path 115) of the airflow generating device 14 are divided in the shared switching cavity 82 after passing through the shared first air duct 58.

[0215] The first air path 111, the third air path 113, and the fourth air path 114 share the exhaust air cavity 83. It can be understood that when negative pressure is drawn for the cooking cavity 22, the exhaust air cavity 83 cannot be connected to the external environment and can only be connected to the cooking cavity 22. When steam is discharged for the cooking cavity 22, the exhaust air cavity 83 needs to be connected to the external environment so that the steam can be discharged to the environment. When cold air is blown for the cooking cavity 22, the exhaust air cavity 83 also needs to be connected to the external environment so that the cold air in the environment can enter the airflow generating device 14. Therefore, the third air path 113 and the fourth air path 114 also share the air duct 84 which is always connected to the environment. The exhaust air cavity 83 is connected to the air duct 84 through the first opening 41, and when the first opening 41 is opened, the exhaust air cavity 83 is connected to the air duct 84. When the first opening 41 is closed, the exhaust air cavity 83 is cut off from the air duct 84.

[0216] The moving partition assembly 36 in the device inner cavity 39 is used to define the exhaust air cavity 83 with a part of the device shell 38. In other words, the moving partition assembly 36 and the device shell 38 respectively provide a part of the cavity wall of the exhaust air cavity 83, and at least one of the moving partition assembly 36 and the device shell 38 is provided with a cavity space for forming the exhaust air cavity 83. For example, the moving partition assembly 36 is movable relative to the device shell 38 (i.e., the device inner cavity 39) between a first open position and a first closed position, and when the moving partition assembly 36 is located at the first open position, the moving partition assembly 36 is away from the part of the device shell 38 and a first opening 41 is formed between the moving partition assembly 36 and the part of the device shell 38 (see FIG. 5). When the moving partition assembly 36 is located at the first closed position, the moving partition assembly 36 is close to the part of the device shell 38 and the first opening 41 is closed. Figure 9), that is, the relative movement between different parts of the cavity wall of the exhaust cavity 83 causes the cavity wall to split, and the split opening is the first opening 41; when the moving baffle assembly 36 is in the first closed position, the moving baffle assembly 36 contacts the said part of the device housing 38, and the different parts of the cavity wall of the exhaust cavity 83 are reattached, and the split of the first opening 41 is closed.

[0217] Further, the cooking appliance 100 is configured to close the first opening 41 in the water absorption process and / or the heat preservation process, so that the exhaust cavity 83 is not in communication with the external environment, but only in communication with the cooking cavity 22; in the boiling maintenance process, the first opening 41 is opened, and the exhaust cavity 83 is in communication with the ventilation cavity 84, so that the exhaust cavity 83 is in communication with the environment. In other words, the cooking appliance 100 is configured to close the first opening 41 by the moving baffle assembly 36 in the water absorption process and / or the heat preservation process; open the first opening 41 by the moving baffle assembly 36 in the boiling maintenance process. Both the first gas path 111 and the fourth gas path 114 are located upstream of the airflow generating device 14 and are used to provide gas to the airflow generating device 14. When negative pressure needs to be extracted, it is ensured that the gas entering the airflow generating device 14 is air in the cooking cavity 22; when cold air needs to be blown, ambient cold air can enter the airflow generating device 14. Thus, the airflow is orderly directed to achieve the desired effect.

[0218] Further, the cooking appliance 100 is configured such that when the second gas path 112 is conducted, the first opening 41 is closed, and the fifth gas path 115 is blocked, so that the gas path for extracting negative pressure works normally; when the fifth gas path 115 is conducted, the first opening 41 is opened, so that the gas path for blowing cold air works normally. Therefore, the first opening 41 and the second opening 42 are opened and closed synchronously (or simultaneously). For example, the cooking appliance 100 is configured such that the moving baffle assembly 36 and the floating sealing assembly 37 can interact with each other (both are action components) to realize linkage. For example, when the moving baffle assembly 36 opens the first opening 41, the moving baffle assembly 36 causes the floating sealing assembly 37 to open the second opening 42. In other words, when the moving baffle assembly 36 is in the first open position, the moving baffle assembly 36 abuts the floating sealing assembly 37 to the second open position. For example, when the moving baffle assembly 36 closes the first opening 41, the moving baffle assembly 36 causes the floating sealing assembly 37 to close the second opening 42. For example, when the floating sealing assembly 37 closes the second opening 42, the floating sealing assembly 37 causes the moving baffle assembly 36 to close the first opening 41. Of course, the moving baffle assembly 36 and the floating sealing assembly 37 can also work under the control of the control device, and the synchronous action of the two can be realized by a software program.

[0219] When the first opening 41 is opened, the third air path 113 for discharging steam is also opened. Thus, discharging steam and blowing cold air for the cooking cavity 22 can be performed simultaneously. Preferably, the cooking appliance 100 is configured such that the first opening 41 is opened under the action of steam pressure in the cooking cavity 22, or the movable partition assembly 36 opens the first opening 41 under the action of steam pressure in the cooking cavity 22. When the movable partition assembly 36 and the floating sealing assembly 37 are linked, the floating sealing assembly 37 opens the second opening 42 under the action of steam pressure in the cooking cavity 22, or the second opening 42 is opened under the action of steam pressure in the cooking cavity 22. That is, in the process of moving the movable partition assembly 36 from the first closed position to the first open position under the action of steam pressure in the cooking cavity 22, the movable partition assembly 36 contacts the floating sealing assembly 37 in the second closed position, and then forces the floating sealing assembly 37 to move together with the movable partition assembly 36, so as to move the floating sealing assembly 37 to the second open position. Thus, the opening of the first opening 41 does not require the participation of electric control components, and the control is simple and cost-saving. Moreover, when the steam in the cooking cavity 22 can drive the movable partition assembly 36 to move, it indicates that a large amount of steam has been generated in the cooking cavity 22, for example, in the maintaining boiling process, at this time, the first opening 41 is opened, which can discharge steam and blow cold air, and exactly meets the needs of preventing overflow in the maintaining boiling process.

[0220] In the present application, the force of the steam top opening the movable partition assembly 36 to open the first opening 41 is, for example, 0.1 N to 5 N, and preferably 0.2 N to 1 N.

[0221] It can be understood that the control device can determine the temperature in the cooking cavity 22 through the sensing data of the temperature sensor, so as to accurately determine whether to enter the maintaining boiling process, and control the air flow generating device 14 to work after determining to enter the maintaining boiling process. Those skilled in the art can adjust the control software and component parameters through experiments, so that the movable partition assembly 36 has opened the first opening 41 under the action of steam in the cooking cavity 22 before the control software confirms to enter the maintaining boiling process.

[0222] Furthermore, to simplify control, the cooking appliance 100 is configured such that the second open position is above the second closed position, and the floating seal assembly 37 moves from the second open position to the second closed position by its own weight. Furthermore, the cooking appliance 100 is configured such that the floating seal assembly 37 is located above the movable partition assembly 36, such that the movable partition assembly 36 is located above the first opening 41 (the floating seal assembly 37 and the first opening 41 are located on either side of the movable partition assembly 36 along the axial direction DA). Furthermore, the first open position is located above the first closed position. When the floating seal assembly 37 moves from the second open position to the second closed position by its own weight, its own weight also causes the movable partition assembly 36 to move from the first open position to the first closed position. That is, during the process of moving from the second open position to the second closed position by its own weight, the floating seal assembly 37 contacts the movable partition assembly 36 in the first open position, forcing the movable partition assembly 36 to move along with the floating seal assembly 37, thereby moving the movable partition assembly 36 to the first closed position.

[0223] Furthermore, in order to simplify control, the cooking appliance 100 is constructed so that the second one-way valve 35 opens the third opening 43 under the action of the air pressure in the switching chamber 82 (that is, the air pressure in the first vent pipe 58, that is, the air pressure at the airflow outlet 16, that is, the air pressure in the second air path 112). In other words, the second one-way valve 35 has an open position or an open state in which it is driven to open by the air pressure in the switching chamber 82. When the air pressure in the switching chamber 82 drops, the second one-way valve 35 is closed (in a closed position or closed state). The second one-way valve 35 includes, for example, an elastic component that deforms under the action of air pressure to open the third opening 43 and returns to its original shape by its own elasticity to close the third opening 43. Thus, the air path integration device 30 does not need to be connected to an electronic control component, the control is simple, the cost is saved, and the cooking appliance 100 is easy to assemble.

[0224] like Figure 7 As shown, the second one-way valve 35 is constructed as an elastic diaphragm covering the third opening 43. When airflow flows through the switching chamber 82, the airflow deforms the elastic diaphragm, for example, flipping it upward in the figure, exposing the third opening 43, thereby opening the second air path 112. When the airflow pressure is insufficient, the elastic diaphragm recovers due to its own elasticity, re-covering the third opening 43 and blocking the second air path 112.

[0225] It can be understood that the force that elastically deforms the second one-way valve 35 needs to be less than the gravity of the floating sealing assembly 37, so that the air flow blown by the air flow generating device 14 is less resistant at the second one-way valve 35 in the water absorption and / or heat preservation process, so that the air flow tends to flow to the third opening 43. In other words, when the air pressure in the switching cavity 82 is less than the gravity corresponding to the preset weight of the floating sealing assembly 37, the floating sealing assembly 37 is located in the second closed position. Those skilled in the art can determine the power of the air flow generating device 14, the gravity of the floating sealing assembly 37 and the elastic deformation capacity of the second one-way valve 35 through experiments, so that the air flow blown by the air flow generating device 14 can deform the second one-way valve 35, but cannot lift the floating sealing assembly 37, realize the conduction of the second air path 112 and the blockage of the fifth air path 115 when the negative pressure is drawn.

[0226] When the floating sealing assembly 37 opens the second opening 42, the second opening 42 is a passage. The second one-way valve 35 closes the third opening 43, so that the resistance at the third opening 43 is greater than the resistance at the second opening 42. Therefore, when the second opening 42 is opened, the air flow in the switching cavity 82 selects the path with small resistance and flows out of the switching cavity 82 from the second opening 42, but not from the third opening 43. In other words, when the second opening 42 is opened, the second opening 42 makes the switching cavity 82 not a closed cavity, and cannot maintain a high air pressure in the switching cavity 82, so that the air pressure cannot deform the second one-way valve 35.

[0227] The first opening 41, the second opening 42 and the third opening 43 are openings on the respective air paths, and can also be regarded as a small air flow passage.

[0228] Due to the position of the cross section, Figure 7 the cross-sectional view fails to show the complete fifth air path 115, Figure 8 the cross-sectional view fails to show the complete second air path 112.

[0229] The specific exemplary structure of the air path integration device 30 will be introduced below.

[0230] As Figures 10 to 26 shown, the air path integration device 30 has a substantially radial symmetry shape, and its axis PA extends in the upward and downward direction, that is, the axial direction DA of the air path integration device 30 is the upward and downward direction. In the projection along the axial direction DA, the device housing 38 is circular with the axis PA as the center.

[0231] The gas flow integration device 30 includes an upper cover 31, an upper divider 32, a lower divider 33, and a lower cover 34. The upper cover 31 and lower cover 34 each form a portion of the device housing 38, and together they enclose an internal cavity 39. The lower cover 34 is located below the upper cover 31, facing the cooking cavity 22 and contacting the bottom wall of the receiving tank 11A. The exhaust pipe 56, third vent pipe 57, first vent pipe 58, and second vent pipe 59 all extend from the bottom surface of the lower cover 34.

[0232] The upper cover 31 of the device is generally constructed in the shape of a top hat, for example, and includes an upper cover top wall 31A, an upper cover side wall 31B, and an upper cover annular wall 31C. The upper cover side wall 31B is generally cylindrical and extends in the axial direction DA. The upper cover top wall 31A is connected to the upper end of the upper cover side wall 31B, forming a top of the hat and constituting the top wall of the gas path integration device 30. The inner peripheral edge of the upper cover annular wall 31C is connected to the outer peripheral surface of the lower end of the upper cover side wall 31B and extends radially outward from the outer periphery of the upper cover side wall 31B to form a brim. The lower cover 34 of the device is generally bowl-shaped and includes a lower cover bottom wall 34A and a lower cover side wall 34B. The axial direction of the lower cover side wall 34B is also the axial direction DA. The lower cover bottom wall 34A is connected to the lower end of the lower cover side wall 34B, forming the bottom wall of the gas path integration device 30, and is used to contact the bottom of the accommodating groove 11A. The lower cover bottom wall 34A extends along a plane, for example, to reduce the difficulty of processing. The outer peripheral edge of the upper cover annular wall 31C is located above the opening of the upper end of the lower cover side wall 34B.

[0233] The upper partition 32 and the lower partition 33 are both disposed in the device cavity 39 to divide the device cavity 39 into a plurality of cavities.

[0234] The lower partition 33 is configured as a disk, for example, and its outer peripheral edge is connected to the inner peripheral surface of the lower cover side wall 34B. The lower partition 33 is connected to the device lower cover 34, for example, by a third rotating buckle 94C (see Figure 11 and Figure 14 The upper partition 32 is located above the lower partition 33.

[0235] The upper end of the upper partition 32 abuts against the upper lid top wall 31A, and the lower end abuts against the lower partition 33. The upper partition 32 is configured as a double-layer structure, and both the upper layer and the lower layer are generally circular grooves with the axial direction DA as the axis. The upper layer groove and the lower layer groove share a groove bottom, and thus the opening directions of the two grooves are opposite. Specifically, the upper partition 32 includes a partition plate 32A, an upper groove side wall 32B, and a lower groove side wall 32C. The partition plate 32A extends, for example, in the horizontal direction, and forms the groove bottom of the upper layer groove and the lower layer groove. The upper groove side wall 32B is, for example, a cylinder extending in the axial direction DA, and is connected to the upper surface of the partition plate 32A, so that the upper layer groove opens upward. The upper end of the upper groove side wall 32B abuts against the upper lid top wall 31A. The lower groove side wall 32C is, for example, also a cylinder extending in the axial direction DA, and is connected to the lower surface of the partition plate 32A, so that the lower layer groove opens downward. The lower end of the lower groove side wall 32C abuts against the lower partition 33. The lower groove side wall 32C and the lower partition 33 are connected, for example, by the second rotation buckle 94B (see Figure 14 ).

[0236] The radial dimension of the upper groove side wall 32B is smaller than the radial dimension of the lower groove side wall 32C. The radial dimension of the upper groove side wall 32B is smaller than the radial dimension of the partition plate 32A. The radial dimension of the lower groove side wall 32C is the same as the radial dimension of the partition plate 32A. The upper groove side wall 32B, the lower groove side wall 32C, and the partition plate 32A are connected to the center, so that the partition plate 32A as a whole forms the groove bottom of the lower layer groove, and the middle part of the partition plate 32A forms the groove bottom of the upper layer groove. That is, the groove bottom of the lower layer groove includes the groove bottom of the upper layer groove, and the groove bottom of the upper layer groove is the middle part of the groove bottom of the lower layer groove.

[0237] Referring to Figure 7 , the opening of the upper layer groove of the upper partition 32 is covered by the upper lid top wall 31A, and the space of the upper layer groove forms the air blowing cavity 81. That is, the upper lid top wall 31A, the partition plate 32A, and the upper groove side wall 32B enclose the air blowing cavity 81. Among them, the upper lid top wall 31A forms the top wall of the air blowing cavity 81, the partition plate 32A forms the bottom wall of the air blowing cavity 81, and the upper groove side wall 32B forms the side wall of the air blowing cavity 81. The air blowing cavity 81 is generally cylindrical in shape.

[0238] The opening of the lower layer groove of the upper partition 32 is covered by the lower partition 33, and the space of the lower layer groove forms the switching cavity 82. That is, the lower partition 33, the partition plate 32A, and the lower groove side wall 32C enclose the switching cavity 82. Among them, the partition plate 32A forms the top wall of the switching cavity 82, the lower partition 33 forms the bottom wall of the switching cavity 82, and the lower groove side wall 32C forms the side wall of the switching cavity 82. The switching cavity 82 is generally cylindrical in shape.

[0239] The upper lid side wall 31B is located outside the upper partition 32. The upper portion of the upper lid side wall 31B is located above the partition 32A. The lower portion of the upper lid side wall 31B is located below the partition 32A and outside the lower tank side wall 32C. The lower portion of the upper lid side wall 31B is connected to the lower tank side wall 32C, for example, by a third rotational snap 94C (see FIG. 9B). Figure 11 and Figure 14 ). Due to the upper tank of the upper partition 32 being thinner than the lower tank, there is an annular space between the upper tank side wall 32B and the upper lid side wall 31B, which forms the exhaust cavity 85. That is, the exhaust cavity 85 is substantially enclosed by the outer portion of the upper lid top wall 31A (the portion outside the air blowing cavity 81), the outer portion of the partition 32A (the portion outside the air blowing cavity 81), the upper tank side wall 32B and the upper portion of the upper lid side wall 31B. Among them, the outer portion of the upper lid top wall 31A forms the top wall of the exhaust cavity 85, the outer portion of the partition 32A forms the bottom wall of the exhaust cavity 85, the upper tank side wall 32B forms the outer side wall of the exhaust cavity 85, and the upper lid side wall 31B forms the inner side wall of the exhaust cavity 85.

[0240] It can be understood that the bottom wall of the upper tank of the upper partition 32, that is, the middle portion of the partition 32A, is a second common cavity wall 52 shared by the air blowing cavity 81 and the switching cavity 82. The second opening 42 is provided on the second common cavity wall 52. The outer portion of the partition 32A is a first common cavity wall 51 shared by the exhaust cavity 85 and the switching cavity 82. The third opening 43 is provided on the first common cavity wall 51. In other words, the partition 32A includes the second common cavity wall 52 and the first common cavity wall 51 connected in the radial direction, and the first common cavity wall 51 is located outside the second common cavity wall 52. The upper tank side wall 32B is connected to the boundary between the first common cavity wall 51 and the second common cavity wall 52. Since the first common cavity wall 51 is annular, multiple third openings 43 and second one-way valves 35 can be provided.

[0241] The space between the lower partition 33 and the device lower cover 34 forms the exhaust cavity 83 and the ventilation cavity 84. Specifically, referring to Figure 15 and Figure 16 , the lower cover bottom wall 34A is provided with an annular wall 83B extending in the axial direction DA, the annular wall 83B is located in the device inner cavity 39, the inner side space of the annular wall 83B is used to form at least part of the exhaust cavity 83, and the outer side space of the annular wall 83B is used to form the ventilation cavity 84. The middle portion of the lower cover bottom wall 34A forms the exhaust cavity bottom wall 83A of the exhaust cavity 83, and the annular wall 83B forms at least part of the exhaust cavity side wall of the exhaust cavity 83. The outer portion of the lower cover bottom wall 34A forms the bottom wall of the ventilation cavity 84, the lower cover side wall 34B forms the side wall of the ventilation cavity 84, and the lower partition 33 forms the top wall of the ventilation cavity 84.

[0242] The annular wall 83B has two ends arranged opposite along the axial direction DA, one of which is connected to the bottom wall 83A of the exhaust cavity. The annular wall 83B is connected to the junction between the intermediate portion and the peripheral portion of the bottom wall 34A of the lower cover. The lower partition 33 is located above the annular wall 83B. The lower partition 33 and the bottom wall 34A of the lower cover are respectively located on both sides of the annular wall 83B along the axial direction DA. The movable partition assembly 36 is arranged on the lower partition 33, and the movable partition assembly 36 and the bottom wall 34A of the lower cover are respectively located on both sides of the annular wall 83B along the axial direction DA. The movable partition assembly 36 is configured to be movable relative to the annular wall 83B along the axial direction DA between a first open position and a first closed position. When the movable partition assembly 36 is located at the first open position, the movable partition assembly 36 and the end of the annular wall 83B not connected to the bottom wall 83A of the exhaust cavity form a first opening 41. Thus, the ventilation cavity 84 is located at the periphery of the annular wall 83B and surrounds the first opening 41. When the movable partition assembly 36 is located at the first closed position, the movable partition assembly 36 contacts the end of the annular wall 83B not connected to the bottom wall 83A of the exhaust cavity, forming at least a top wall of the exhaust cavity 83. The first opening 41 can be understood as being formed in the side wall of the exhaust cavity 83, and when the first opening 41 is opened, the side wall of the exhaust cavity 83 is broken along the circumference. The exhaust cavity 83 can also be understood as a section of airflow passage, and the first opening 41 can be understood as an opening of the section of airflow passage.

[0243] The cavity wall of the exhaust cavity 83 is provided with an exhaust port 83C connected to the exhaust pipe 56, so that the exhaust cavity 83 communicates with the cooking cavity 22. The cavity wall of the exhaust cavity 83 is provided with an exhaust port 83D connected to the third ventilation pipe 57, so that the exhaust cavity 83 communicates with the airflow inlet 15. The exhaust port 83C and the exhaust port 83D are preferably arranged on the same cavity wall of the exhaust cavity 83, for example, both are arranged on the exhaust cavity bottom wall 83A. Thus, the bottom wall 34A of the lower cover, the third ventilation pipe 57 and the exhaust pipe 56 can be integrally formed.

[0244] The housing opening 55 is arranged on the device upper cover 31. For example, see Figure 12 The housing opening 55 includes a first housing opening 55A arranged on the annular wall 31C. See Figure 24 The lower partition 33 is provided with a ventilation hole 33A near the edge. See Figure 7 The ventilation hole 33A and the first housing opening 55A are arranged along the axial direction DA. The ventilation cavity 84 communicates to the first housing opening 55A through the ventilation hole 33A, thereby communicating with the environment. See Figure 10 and Figure 11 The housing opening 55 further includes a second housing opening 55B arranged on the upper portion of the upper cover side wall 31B, and the second housing opening 55B is used to communicate the exhaust cavity 85 with the environment. See Figure 1When the gas path integration device 30 is mounted to the cover 10, the device upper cover 31 protrudes from the upper surface of the face cover 13, for example, so that the first housing aperture 55A and the second housing aperture 55B are in communication with the environment.

[0245] The first vent tube 58 is provided on the lower partition 33. The first vent tube 58 extends in the axial direction DA in the device inner cavity 39 through the vent cavity 84 and out of the through hole 34C on the lower cover bottom wall 34A. The first vent tube 58 can be integrally formed with the lower partition 33. The second vent tube 59 is provided on the middle portion of the partition 32A (see Figure 8 ), that is, the bottom wall of the blowing cavity 81. The second vent tube extends in the axial direction DA in the device inner cavity 39 through the switching cavity 82 and the vent cavity 84 and out of the through hole 34D on the lower cover bottom wall 34A. The lower partition 33 is provided with a through hole 33D (see Figure 24 ) for the second vent tube 59 to pass through. Both the first vent tube 58 and the second vent tube 59 are located outside the annular wall 83B, so as not to affect the gas path function of the pumping and exhaust cavity 83.

[0246] As mentioned above, the upper partition 32 is connected to the lower partition 33 by the second rotating buckle 94B, that is, the two need to be relatively rotated, and the second vent tube 59 needs to pass through the lower partition 33, so the second vent tube 59 cannot be integrally formed with the upper partition 32. The second vent tube 59 is detachably connected to the partition 32A. As shown in Figure 8 , the partition 32A is provided with a partition connecting portion 32D for detachable connection with the second vent tube 59. The partition connecting portion 32D is configured as an internally threaded tube (or hole) extending in the axial direction DA, for example, and the outer periphery of the second vent tube 59 is provided with an external thread for screwing connection with the partition connecting portion 32D. When the upper partition 32 and the lower partition 33 are buckled in place, the partition connecting portion 32D is aligned with the through hole 33D of the lower partition 33.

[0247] When assembling the gas path integration device 30, the second one-way valve 35 and the floating sealing assembly 37 are first mounted to the partition 32A, and the moving partition assembly 36 is mounted to the lower partition 33. Then the upper partition 32 and the lower partition 33 are screwed and buckled. Next, the second vent tube 59 is mounted to the partition connecting portion 32D. Finally, the device lower cover 34 is screwed and buckled with the lower partition 33, and the device upper cover 31 is screwed and buckled with the upper partition 32.

[0248] In order not to affect the functions of the various cavities in the device inner cavity 39, a plurality of sealing members are also provided in the device inner cavity. In order to ensure that the pumping and exhaust cavity 83 and the vent cavity 84 are not in communication in the pumping negative pressure mode, a first sealing member 91A is provided between the moving partition assembly 36 and the device housing 38. The first sealing member 91A is a sealing ring, for example, which straddles the end of the annular wall 83B (see Figure 9). A second seal 91B is also provided between the lower groove side wall 32C of the upper partition 32 and the edge of the lower partition 33 for sealing the switching cavity 82. Meanwhile, the upper cover side wall 31B is close to the lower groove side wall 32C, so that the second seal 91B is also connected between the upper cover side wall 31B and the edge of the lower partition 33. Thus, the second seal 91B is used for sealing between the exhaust cavity 85, the switching cavity 82 and the ventilation cavity 84. A third seal 91C is provided between the upper groove side wall 32B of the upper partition 32 and the upper cover top wall 31A for sealing between the blowing cavity 81 and the exhaust cavity 85. The third seal 91C is, for example, a sealing ring, which is, for example, straddled on the end of the upper groove side wall 32B (see Figure 8 In order not to affect the gas path function of the switching cavity 82, a fourth seal 91D is provided at the through hole 33D of the lower partition 33 for sealing contact between the second ventilation tube 59 and the through hole 33D, so that the switching cavity 82 is not communicated with the ventilation cavity 84. A fifth seal 91E is provided in the through hole 32E of the partition connecting portion 32D, so that the second ventilation tube 59 is sealingly connected with the partition connecting portion 32D for sealing between the blowing cavity 81 and the switching cavity 82.

[0249] The ventilation cavity 84 is used to communicate with the environment, so the through holes 34C and 34D do not need to be sealed. It can be understood that when the device lower cover 34 is screwed and engaged with the lower partition 33, the first ventilation tube 58 has been located in the through hole 34C, and the second ventilation tube 59 has been located in the through hole 34D. The through holes 34C and 34D reserve enough space for the corresponding gas tubes to move therein. As shown in Figure 13 , the through holes 34C and 34D are both long holes. When the device lower cover 34 just contacts the lower partition 33 in the axial direction DA, the two gas tubes are located at one end of the corresponding long hole (such as the black marked position in the figure). After the device lower cover 34 is screwed and engaged with the lower partition 33 (such as the red arrow direction in the figure), the two gas tubes are located at the other end of the corresponding long hole (such as the blue marked position in the figure).

[0250] As shown in Figure 14 and Figures 18 to 20 , the second one-way valve 35, the floating sealing assembly 37, the upper partition 32 and the third seal 91C can be pre-assembled to form an upper partition pre-assembled assembly 53. As shown in Figure 14 and Figures 21 to 23 , the moving partition assembly 36 and the lower partition 33 can be pre-assembled to form a lower partition pre-assembled assembly 54. The upper partition pre-assembled assembly 53 and the lower partition pre-assembled assembly 54 are connected through the second rotation buckle 94B. After the upper partition pre-assembled assembly 53 and the lower partition pre-assembled assembly 54 are connected, the upper cover 31 is connected with the upper partition pre-assembled assembly 53 through the first rotation buckle 94A, and the lower cover 34 is connected with the lower partition pre-assembled assembly 54 through the third rotation buckle 94C.

[0251] The structure and mounting method of the movable partition assembly 36 will be described below.

[0252] Referring to Figure 24 , the lower partition 33 is provided with a mounting structure 33B for mounting the movable partition assembly 36, the mounting structure 33B including a mounting through hole 33C. The movable partition assembly 36 is disposed through the mounting through hole 33C. The mounting through hole 33C is, for example, a circular hole. The axial direction of the first opening 41 is parallel to the axial direction of the mounting through hole 33C, both being the axial direction DA. As shown in Figure 9 , the first opening 41 is spaced apart from the mounting through hole 33C along the axial direction DA. The movable partition assembly 36 is connected to the mounting through hole 33C and is movable relative to the mounting through hole 33C along the axial direction DA between the first open position and the first closed position.

[0253] As shown in Figures 7 to 9 and Figures 27 to 29 , the movable partition assembly 36 includes an expansion member 61, a movable partition 64, and a pressing ring 65.

[0254] The expansion member 61 is connected to the periphery of the mounting through hole 33C and is expandable in the axial direction DA of the mounting through hole 33C between the first open position and the first closed position. The movable partition 64 defines an exhaust cavity 83 with part of the device housing 38. The movable partition 64 is disposed through the mounting through hole 33C and is connected to the expansion member 61 to move synchronously with the expansion member 61 between the first open position and the first closed position. Thus, the opening and closing of the first opening 41 is achieved by the movement of the movable partition 64.

[0255] The expansion member 61 has, for example, a radial symmetry structure, including an expansion member peripheral portion 61A and an expansion member intermediate portion 61B, the expansion member peripheral portion 61A being connected to the expansion member intermediate portion 61B at the periphery of the expansion member intermediate portion 61B. The expansion member peripheral portion 61A is in the shape of a circular ring for connection to the periphery of the mounting through hole 33C. The expansion member intermediate portion 61B is configured to extend through the mounting through hole 33C and be movable relative to the expansion member peripheral portion 61A in the axial direction DA of the mounting through hole 33C between the first open position and the first closed position in the mounting through hole 33C.

[0256] The movable partition 64 is connected to the side of the expansion member intermediate portion 61B facing the first opening 41 and moves synchronously with the expansion member intermediate portion 61B between the first open position and the first closed position. In the first embodiment, the movable partition 64 moves from the first closed position (see Figure 25 ) to the first open position (see Figure 26) to move the middle part 61B of the telescopic member from the first open position to the first closed position. The middle part 61B of the telescopic member is moved from the first open position to the first closed position under the action of the floating seal assembly 37 to move the moving partition 64 from the first open position to the first closed position.

[0257] The main part of the pressing ring 65 is a pressing ring 67, which is configured as a circular ring and matches the shape of the outer peripheral part 61A of the telescopic member, and is used to contact the outer peripheral part 61A of the telescopic member so that the outer peripheral part 61A of the telescopic member is clamped between the pressing ring 67 and the mounting structure 33B, i.e., the outer peripheral part 61A of the telescopic member is pressed around the mouth of the mounting through hole 33C. Thus, the position of the outer peripheral part 61A of the telescopic member is fixed, i.e., the relative position of the outer peripheral part 61A of the telescopic member to the first opening 41 is fixed. The outer peripheral part 61A of the telescopic member can move in the axial direction DA in the central through hole of the pressing ring 67. The pressing ring 65 further includes a pressing ring connecting part 66, which is used to connect the mounting structure 33B, for example, detachably connect the mounting structure 33B. For example, the pressing ring connecting part 66 is arranged on the radially outer side of the inner peripheral surface of the pressing ring 67 and is connected to the mounting structure 33B by bolts. The telescopic member 61 is connected to the side of the mounting through hole 33C away from the first opening 41, so as to facilitate the installation of the pressing ring 65.

[0258] The telescopic member 61 is preferably made of elastic material. It can be understood that, since the outer peripheral part 61A of the telescopic member is connected around the mouth of the mounting through hole 33C, the telescopic member 61 can seal the mounting through hole 33C, so as to isolate the switching cavity 82 from the ventilation cavity 84 and isolate the switching cavity 82 from the exhaust cavity 83. The middle part 61B of the telescopic member includes a pleated structure 61C. The pleated structure 61C is configured to extend in the radial direction DR and is concave-convex in the axial direction DA. Due to the use of elastic material, the pleated structure 61C can be stretched and reset. When the pleated structure 61C is stretched, the middle part 61B of the telescopic member moves away from the outer peripheral part 61A in the axial direction DA, which drives the moving partition 64 to move away from the first opening 41 in the axial direction DA, so as to open the first opening 41. When the pleated structure 61C is reset, the middle part 61B of the telescopic member moves toward the outer peripheral part 61A in the axial direction DA, which drives the moving partition 64 to move toward the first opening 41 in the axial direction DA, so as to close the first opening 41. In other words, the moving partition 64 has a first open position and a first closed position, and the middle part 61B of the telescopic member is configured to be telescopic in the axial direction DA to correspond to the switching of the moving partition 64 between the first open position and the first closed position.

[0259] The movable partition 64 can include a partition connecting portion 64B and a partition flange plate 64A. The partition connecting portion 64B extends in the axial direction DA, and an end of the partition connecting portion 64B distal to the first opening 41 is connected to the side of the telescopic member intermediate portion 61B facing the first opening 41. The partition flange plate 64A is provided on the outer circumferential side of the partition connecting portion 64B, and is configured to contact the device housing 38, i.e., to open and close the first opening 41. The outer diameter of the partition flange plate 64A is not less than the diameter of the first opening 41. The partition connecting portion 64B extends through the mounting through-hole 33C, and is movable in the axial direction DA relative to the mounting through-hole 33C between the first open position and the first closed position in the mounting through-hole 33C.

[0260] The partition connecting portion 64B can have a small radial dimension to save material. Correspondingly, the mounting through-hole 33C, the telescopic member 61, and the compression ring 65 can all have small dimensions. The radial dimension of the partition flange plate 64A can be greater than the diameter of the mounting through-hole 33C, so that the partition flange plate 64A is always located on the side of the mounting through-hole 33C facing the first opening 41, i.e., the partition flange plate 64A is always located in the air passage cavity 84. The partition flange plate 64A is connected to the end of the partition connecting portion 64B in the axial direction DA, so that the axial dimension of the partition connecting portion 64B can be reduced.

[0261] Preferably, the telescopic member intermediate portion 61B is detachably connected to the movable partition 64. The movable partition 64 (in particular, the partition connecting portion 64B) is provided with a partition flange 64H, and the telescopic member intermediate portion 61B is tightly fitted with the partition flange 64H. For example, the outer circumferential surface of the movable partition 64 is configured with a radially outward annular partition flange 64H extending in the circumferential direction, and the inner circumferential surface of the side of the telescopic member intermediate portion 61B facing the first opening 41 is configured with a second groove 61H extending in the circumferential direction, the groove opening and groove bottom of the second groove 61H being opposite in the radial direction DR, and configured to accommodate the annular flange 64H. The movable partition 64 is made of a hard material (plastic, metal, etc.), and the partition flange 64H can be tightly fitted with the partition flange 64H by using the elasticity of the telescopic member 61. For example, the inner circumferential surface of the side of the telescopic member intermediate portion 61B facing the first opening 41 is configured with a radially inward annular protrusion 61E extending in the circumferential direction, and the outer circumferential surface of the partition flange 64H is configured with a first groove 64E extending in the circumferential direction, the groove opening and groove bottom of the first groove 64E being opposite in the radial direction DR, and configured to accommodate the annular protrusion 61E. The movable partition 64 can press and deform the telescopic member 61 by using the elasticity of the telescopic member 61, so that the annular protrusion 61E can enter the first groove 64E.

[0262] Preferably, the partition flange plate 64A is provided with a reinforcing rib 69 for reinforcing the strength of the partition flange plate 64A. The reinforcing rib 69 protrudes from the surface of the partition flange plate 64A. Preferably, the reinforcing rib 69 is arranged on the side of the partition flange plate 64A facing the first opening 41, so that the size of the partition connecting portion 64B in the axial direction DA can be reduced. The reinforcing rib 69 is configured, for example, as an annular rib, and can be located inside the annular wall 83B.

[0263] Further, the mounting structure 33B is provided with at least one guide post 48 extending in the axial direction DA towards the first opening 41, for example, the side of the lower partition 33 facing the device lower cover 34 is provided with at least one guide post 48 extending in the axial direction DA, and the partition flange plate 64A of the moving partition 64 is provided with at least one guide hole 64D for accommodating the guide post 48. The guide post 48 is arranged corresponding to the guide hole 64D, and the guide post 48 is movable in the axial direction DA in the guide hole 64D. Thus, the guide post 48 and the guide hole 64D enable the moving partition 64 to be stably moved in the axial direction DA. A plurality of guide posts 48 and guide holes 64D can be uniformly distributed in the circumferential direction. As shown in Figure 24 As shown in Figure 25 and Figure 26 As shown in

[0264] As shown in Figure 27 The partition flange plate 64A is also provided with a through hole 64F for the first air vent pipe 58 to pass through and a through hole 64G for the second air vent pipe 59 to pass through. The first air vent pipe 58 and the second air vent pipe 59 also have a guiding effect on the movement of the moving partition 64. From Figure 24 It can be seen that the guide post 48, the first air vent pipe 58 and the second air vent pipe 59 are generally distributed on the same circle with the axis PA as the center.

[0265] As mentioned earlier, the steam exhaust third air path 113 and the cold air blowing fourth air path 114 of the cooking appliance 100 are simultaneously conducted, that is, the steam exhaust and the cold air blowing are simultaneously performed, and the two air paths share the exhaust air cavity 83 and the air vent cavity 84. In the exhaust air cavity 83 and the air vent cavity 84, the third air path 113 and the fourth air path 114 have opposite air flow directions and different air flow temperatures.

[0266] In order to make the hot steam that needs to move along the third air path 113 as little as possible to enter the fourth air path 114, as Figure 15 and Figure 16As shown, the bottom wall 83A of the exhaust chamber is further provided with a first barrier 45, located between the exhaust port 83D and the exhaust port 83C. The first barrier 45 protrudes from the bottom wall 83A toward the interior of the exhaust chamber 83, somewhat blocking air flow between the exhaust port 83D and the exhaust port 83C. In other words, the first barrier 45 divides the exhaust chamber 83 into a steam exhaust side 83E and a cold air connection side 83F. As will be appreciated, the exhaust port 83C is located on the steam exhaust side 83E, while the exhaust port 83D is located on the cold air connection side 83F.

[0267] Furthermore, a second barrier 49 is provided in the ventilation cavity 84. The lower side of the second barrier 49 is connected to the lower cover bottom wall 34A and the lower cover side wall 34B, and its upper edge conforms to the bottom shape of the lower divider 33, thereby roughly dividing the ventilation cavity 84 into two. Preferably, the second barrier 49 is located in the extension direction of the first barrier 45, that is, on the extension line of the first barrier 45, and together with the first barrier 45, it serves to separate the cold and hot air flows. Due to the radial arrangement of the exhaust cavity 83 and the ventilation cavity 84, two second barriers 49 are provided in the ventilation cavity 84, corresponding to the two side edges 46 of the first barrier 45 and extending on the extension line of the first barrier 45.

[0268] like Figure 7 As shown, after hot steam enters the exhaust chamber 83 from the exhaust pipe 56 along the blue third air path 113, due to the blocking effect of the first blocking member 45, most of the steam enters the ventilation chamber 84 from the side of the first blocking member 45 facing the exhaust port 83C, and is then discharged into the environment from the side of the second blocking member 49 facing the exhaust port 83C. The reinforcing rib 69 extends toward the exhaust chamber 83 and is located inside the annular wall 83B. The reinforcing rib 69 and the first blocking member 45 are staggered in the axial direction DA, forming a double barrier with the first blocking member 45 to a certain extent, further hindering the movement of hot steam toward the exhaust port 83D. Preferably, the reinforcing rib 69 is located between the first blocking member 45 and the annular wall 83B in the radial direction DR. The parts of the exhaust chamber 83 and the ventilation chamber 84 located on the side of the two blocking members facing the exhaust port 83C are occupied by hot steam, while the ambient cold air tends to enter the ventilation chamber 84 from the side of the second blocking member 49 facing the exhaust port 83D, and then enter the exhaust chamber 83 from the side of the first blocking member 45 facing the exhaust port 83D.

[0269] like Figures 15 to 17As shown, preferably, the width direction spaced two side edges 46 of the first barrier 45 are connected to the annular wall 83B to more fully block the suction port 83D and the exhaust port 83C. Preferably, the width direction middle portion 47 of the first barrier 45 protrudes from the annular wall 83B toward the moving baffle assembly 36 in the axial direction DA to more fully block the suction port 83D and the exhaust port 83C. The baffle connecting portion 64B of the moving baffle assembly 36 includes a receiving slot 64C (see Figure 28 ) having an opening facing the first opening 41 for receiving the middle portion 47 of the first barrier 45. In this way, the middle portion 47 of the first barrier 45 can have a certain height to facilitate the isolation of the hot steam and the ambient cold air. To accommodate the shape of the mounting through hole 33C, the baffle connecting portion 64B is generally cylindrical in shape, and thus the receiving slot 64C is a circular slot. To extend the effective length of the middle portion 47 of the first barrier 45, the middle portion 47 of the first barrier 45 includes an arc-shaped plate having an arc axis generally coinciding with the axis of the annular wall 83B. The arc of the arc-shaped plate is, for example, 90 degrees to 180 degrees. The first barrier 45, the annular wall 83B, the exhaust pipe 56, the third air pipe 57, and the device lower cover 34 can be integrally formed.

[0270] It can be understood that the receiving slot 64C is also part of the cavity space of the suction and exhaust cavity 83.

[0271] Preferably, the axis of the exhaust port 83C generally coincides with the axis of the annular wall 83B, so that the steam can uniformly act on the moving baffle 64. Preferably, the diameter of the exhaust port 83C is greater than the diameter of the suction port 83D, which facilitates the steam to quickly enter the suction and exhaust cavity 83 and occupy the third air path 113.

[0272] When the mobile partition assembly 36 is in the first open position, the air path integration device 30 is in a blowing mode of blowing air into the cooking cavity 22, the housing opening 55, the air passage cavity 84, the first opening 41, the air exhaust cavity 83 (specifically, the cold air communication side 83F), the third air passage tube 57, the airflow generating device 14, the first air passage tube 58, the combined cavity 86, and the second air passage tube 59 can form an internal blowing air path (an air path of blowing cold air into the cooking space 22) in communication. Among them, the housing opening 55, the air passage cavity 84, the first opening 41, and the cold air communication side 83F form a cold air inlet air path in communication. The air in the external environment enters the airflow generating device 14 through the air exhaust cavity 84, the tubular connecting portion 57, and the airflow inlet 15. At the same time, the air path integration device 30 is also in an exhaust mode, and the exhaust pipe 56, the steam exhaust side 83E, the first opening 41, the air passage cavity 84, and the housing opening 55 form a steam exhaust air path. When the mobile partition assembly 36 is in the first closed position, the air path integration device 30 is in a suction mode of sucking air into the cooking cavity 22, and the air exhaust cavity 83 is separated from the air passage cavity 84. The exhaust pipe 56, the air exhaust cavity 83, the third air passage tube 57, the airflow generating device 14, the first air passage tube 58, and the combined cavity 86 (specifically, the switching cavity 82) can form an external suction air path (an air path of sucking negative pressure into the cooking space 22) in communication. The gas in the cooking cavity 22 enters the airflow generating device 14 through the exhaust pipe 56, the air exhaust cavity 83, the tubular connecting portion 57, and the airflow inlet 15.

[0273] In the present application, preferably, the axes of the device upper cover 31, the upper partition 32, the lower partition 33, the device lower cover 34, the mounting through hole 33C, the mobile partition assembly 36, and the annular wall 83B are all the axis PA of the air path integration device 30.

[0274] In some embodiments not shown in the present application, the lower cover bottom wall 34A does not extend along a plane, wherein the middle portion and the outer peripheral portion are not in the same plane, for example, wherein the middle portion is recessed downward relative to the outer peripheral portion, for example, the annular wall 83B constitutes part of the outer surface of the device housing 38.

[0275] In some embodiments not shown in the present application, the cavity space of the air exhaust cavity 83 is completely provided by the mobile partition assembly 36. For example, the lower cover 34 does not provide the annular wall 83B, the reinforcing ribs 69 of the mobile partition 64 of the mobile partition assembly 36 form the side wall of the air exhaust cavity 83, the accommodation groove 64C forms the cavity space of the air exhaust cavity 83, and the lower cover bottom wall 34A forms the bottom wall of the air exhaust cavity 83. The first sealing member 91A is sleeved on the reinforcing rib 69.

[0276] The structure and installation method of the floating sealing assembly 37 are described below.

[0277] As described above, the floating sealing assembly 37 extends through the second opening 42. As shown in FIG. 4, the floating sealing assembly 37 is arranged on the second opening 42 of the device housing 38. Figures 30 to 32 As shown, the floating seal assembly 37 includes a floating member 71 and a blocking member 75. The floating member 71 is configured to extend through the second opening 42 and is movable in the axial direction DA in the second opening 42. The floating member 71 includes a floating member first end portion 71A and a floating member second end portion 71B disposed opposite to each other in the axial direction DA. The floating member first end portion 71A extends out of the second opening 42. There is a gap between at least a portion of the floating member 71 and the inner circumferential surface of the second opening 42. The blocking member 75 is connected to the floating member first end portion 71A and is configured to block the second opening 42 at one end of the second opening 42. For example, the blocking member 75 has a radial dimension greater than that of the second opening 42, so that the blocking member 75 closes the second opening 42 by covering the second opening 42. At the same time, the blocking member 75 also allows the floating member 71 to have a limit position when moving toward the side of the floating member second end portion 71B.

[0278] The blocking member 75 is preferably made of an elastic material. The blocking member 75 can also be understood as a sealing member. The blocking member 75 is configured as an elastic diaphragm, for example, which covers the second opening 42 at one end (one side) of the second opening 42. The elastic diaphragm is provided with a diaphragm mounting hole 76 through which the floating member first end portion 71A passes, so that the elastic diaphragm is sleeved on the outer periphery of the floating member first end portion 71A. For example, the outer periphery of the floating member first end portion 71A is provided with a first mounting groove 71E extending in the circumferential direction, which is configured to accommodate the portion of the elastic diaphragm located around the mouth of the diaphragm mounting hole 76, i.e., to clamp the elastic diaphragm in the first mounting groove 71E.

[0279] The floating member second end portion 71B also extends out of the second opening. The floating seal assembly 37 further includes a limiting member 77 connected to the floating member second end portion 71B, and the limiting member 77 has a radial dimension greater than that of the second opening 42. Thus, the limiting member 77 allows the floating member 71 to have a limit position when moving toward the side of the floating member first end portion 71A. The limiting member 77 is sleeved on the outer periphery of the floating member second end portion 71B, for example. The limiting member 77 can be configured as a limiting ring made of an elastic material, for example. The outer periphery of the floating member second end portion 71B is provided with a second mounting groove 71F extending in the circumferential direction, for example, which is configured to accommodate the limiting member 77, i.e., to clamp the limiting member in the second mounting groove 71F.

[0280] The floating member 71 also includes a floating member connecting portion 71C located between the first end portion 71A and the second end portion 71B. The floating member connecting portion 71C extends through the second opening 42 and is movable in the axial direction DA within the second opening 42 between a second open position and a second closed position. A gap is defined between the floating member connecting portion 71C and the inner circumferential surface of the second opening 42. For example, when the blocking member 75 contacts the periphery of one side of the second opening 42, the floating seal assembly 37 is in the second closed position. When the blocking member 75 is removed from the partition 32A, the floating seal assembly 37 is in the second open position. In the second open position, the floating member connecting portion 71C is located within the second opening 42, with a gap between the floating member connecting portion 71C and the inner wall of the second opening 42, thereby allowing airflow through the gap and opening the fifth air path 115.

[0281] For example, the radial dimension of the floating member connection portion 71C is smaller than the radial dimension of the second opening 42, thereby providing a clearance fit between the floating member connection portion 71C and the second opening 42. The radial dimension of the floating member connection portion 71C is 0.1 mm to 10 mm smaller than the radial dimension of the second opening 42. More preferably, the radial dimension of the floating member connection portion 71C is 0.2 mm to 2 mm smaller than the radial dimension of the second opening. Alternatively, the outer circumferential surface of the floating member connection portion 71C may be provided with at least one third groove extending in the axial direction DA, thereby providing a clearance between the floating member connection portion 71C and the inner circumferential surface of the second opening 42.

[0282] In the first embodiment, the axial direction DA is the vertical direction. The first end 71A of the floating member is located above the second end 71B of the floating member. The first end 71A of the floating member is located above the second opening 42, and the second end 71B of the floating member is located below the second opening 42. The second end 71B of the floating member is configured to receive the action of the movable diaphragm assembly 36 to move upward from the second closed position to the second open position. The floating seal assembly 37 moves downward from the second open position to the second closed position under its own weight. The mass (preset weight) of the floating seal assembly 37 is, for example, 1g to 50g. More preferably, the mass of the floating seal assembly 37 is, for example, 5g to 20g.

[0283] As mentioned above, the preset weight of the floating seal assembly 37 needs to be adapted to the deformation capacity of the second one-way valve 35. It can be understood that when the steam lifts the movable partition assembly 36, the steam overcomes the weight of the movable partition 64, the weight of the floating seal assembly 37 and the deformation force of the elastic member 61, so that the movable partition 64 is separated from the first seal 91A on the annular wall 83B. When the steam pressure is not enough to overcome the weight of the movable partition 64, the weight of the floating seal assembly 37 and the deformation force of the elastic member 61, the movable partition 64 is attached to the first seal 91A, so that the cooking cavity 22 has a certain pressure (for example, 3kPa to 4kPa). Therefore, the weight of the floating seal assembly 37 can be adapted to the micro-pressure of the cooking cavity 22. For example, the floating seal assembly 37 further comprises a counterweight 78 arranged at the first end 71A of the floating member and above the blocking member 75. The total weight of the floating seal assembly 37 can be adjusted by adjusting the weight of the counterweight 78.

[0284] The force applied by the steam to the movable partition assembly 36 is related to the effective area of the movable partition 64. The effective area of the movable partition 64 is the area of the part exposed to the exhaust cavity 83, or the area of the movable partition 64 that can be contacted by the steam when the movable partition assembly 36 is in the first closed position. When the movable partition assembly 36 is in the first closed position, the area of the movable partition 64 that can be contacted by the steam is the area of the movable partition 64 inside the annular wall 83B. Preferably, the inner diameter of the annular wall 83B is 10mm to 100mm, more preferably 10mm to 50mm, more preferably 10mm to 40mm or 15mm to 50mm, more preferably 20mm to 30mm. The size of the first seal 91A matches the diameter of the annular wall 83B.

[0285] The first vent pipe 58 is located outside the annular wall 83B, and the distance from the center point of the first vent pipe 58 to the center line point (axis PA) of the annular wall 83B is, for example, 17.5mm to 60mm, preferably 22.5mm to 35mm.

[0286] The second vent pipe 59 is located outside the annular wall 83B, and the distance from the center point of the second vent pipe 59 to the center line point (axis PA) of the annular wall 83B is, for example, 12.5mm to 55mm, preferably 17.5mm to 30mm.

[0287] The following describes other embodiments of the present application, and the same contents as the first embodiment will not be described again.

[0288] In the second embodiment shown in Figure 33 and the third embodiment shown in Figure 34 , the movable partition assembly 36 (for example, the movable partition 64 thereof) is connected with an elastic member, for example, a spring, and is moved from the first open position to the first closed position under the action of the spring.

[0289] like Figure 33 As shown, a second spring 92B is sleeved around the outer periphery of the guide post 48. One end of the second spring 92B abuts the mounting structure 33B of the lower partition 33, and the other end abuts the partition flange 64A. When the movable partition 64 is pushed open by steam, the second spring 92B is compressed. When the steam pressure is insufficient, the second spring 92B returns to its original position, pushing the movable partition 64 back to the first closed position.

[0290] like Figure 34 As shown, the first spring 92A extends in the axial direction DA, with one end connected to the exhaust chamber bottom wall 83A and the other end connected to the movable partition 64. For example, the first spring 92A extends into the receiving groove 64C and connects to the partition connection portion 64B. When the movable partition 64 is pushed open by steam, the first spring 92A is stretched. When the steam pressure is insufficient, the first spring 92A returns to its original position, pulling the movable partition 64 back to the first closed position.

[0291] like Figure 35 As shown, in the fourth embodiment, the movable partition 64 is provided with a first magnet 93A, and a second magnet 93B is provided in the device cavity 39, for example, on the inner side of the bottom wall 34A of the lower cover. The magnetic force between the first magnet 93A and the second magnet 93B attracts each other, and the direction of the magnetic force is parallel to the axial direction DA. Since the internal structure of the ventilation cavity 84 is relatively simple, the second magnet 93B is provided on the bottom wall 84A of the ventilation cavity, that is, on the outside of the annular wall 83B. Accordingly, the first magnet 93A is provided on the partition flange plate 64A at a position outside the first opening 41. Multiple pairs (for example, 2-4 pairs) of the first magnet 93A and the second magnet 93B can be evenly distributed along the circumferential direction.

[0292] In the second to fourth embodiments, the movable partition assembly 36 no longer relies on the weight of the floating seal assembly 37 to move from the first open position to the first closed position, but instead relies on the force of other return components. Once the movable partition assembly 36 returns, the floating seal assembly 37 can fall back under its own weight. In these embodiments, the force driving the movable partition assembly 36 toward the first open position is relatively greater, allowing the pressure in the cooking chamber 22 to be relatively higher before steam is exhausted.

[0293] exist Figure 36In the fifth embodiment shown, the floating sealing assembly 37 is moved from the second open position to the second closed position under the action of the third spring 92C. The third spring 92C is located between the upper cover top wall 31A and the floating member 71. When the steam pushes the floating sealing assembly 37 to the second open position by moving the baffle assembly, the third spring 92C is compressed. When the steam pressure drops, the third spring 92C restores and pushes the floating sealing assembly 37 back in the opposite direction, and pushes the moving baffle assembly 36 back to the first closed position through the floating sealing assembly 37. It can be understood that in this embodiment, the axial direction DA can not be the up-down direction.

[0294] Figure 37 The sixth embodiment shown is similar to the fifth embodiment, and also uses a flexible member to act on the floating sealing assembly 37. In this embodiment, the spring is replaced by a flexible sleeve 96.

[0295] In the fifth and sixth embodiments, when the moving baffle assembly 36 moves towards the first open position, the moving baffle assembly 36 moves the floating sealing assembly 37 towards the second open position; when the floating sealing assembly 37 moves towards the second closed position, the floating sealing assembly 37 moves the moving baffle assembly 36 towards the first closed position. When the axial direction DA is the up-down direction, the floating sealing assembly 37 can reduce the self-weight due to the force exerted by the flexible member on the floating sealing assembly 37 to block the second opening 42.

[0296] In the fifth and sixth embodiments, the flexible member exerts a preset pressure on the floating sealing assembly 37, and when the air pressure in the switching cavity 82 is less than the preset pressure, the flexible member causes the floating sealing assembly 37 to be located at the second closed position.

[0297] In Figure 38 In the seventh embodiment shown, the flexible member is replaced by a temperature-sensitive deforming component 95, such as a memory spring or a bimetallic strip. In this embodiment, the axial direction DA is the up-down direction. The temperature-sensitive deforming component 95 is arranged, for example, on the side of the blocking member 75 facing the second opening 42. At low temperatures, the temperature-sensitive deforming component 95 is in a contracted state, and the floating sealing assembly 37 relies on its own gravity to allow the blocking member 75 to block the second opening 42. When the cooking process enters the boiling maintenance process, the temperature of each part of the cooking appliance 100 rises, and the air path integration device 30 also rises in temperature. After the temperature-sensitive deforming component 95 is heated, it automatically deforms and expands, and the blocking member 75 is lifted away from the second opening 42. After the temperature drops, the memory spring restores its elasticity and is compressed by the counterweight 78, so that the blocking member 75 can cover the mouth of the second opening 42. After the temperature drops, the bimetallic strip returns to its original state, so that the floating sealing assembly 37 can fall back.

[0298] In Figure 39In the eighth embodiment shown, the floating seal assembly 37 is moved between the second open position and the second closed position by a driving assembly 130 of the cooking utensil. The driving assembly 130 includes, for example, a lever 131 and a driving device 132 that applies force to one end of the lever 131, and the other end of the lever 131 applies force to the floating seal assembly 37. In this embodiment, the driving device 132 can be electrically connected to the control device, so that the floating seal assembly 37 can be positioned in the corresponding position in the corresponding cooking process in coordination with the control of the cooking process in the control software. For example, when the control software confirms that the cooking process enters the boiling-maintaining process, the driving device 132 drives the lever 131 to act, so that the floating seal assembly 37 is positioned in the second open position; when the control software confirms that the cooking process enters the heat-keeping process, the driving device 132 drives the lever 131 to act, so that the floating seal assembly 37 is positioned in the second closed position. When the floating seal assembly 37 moves toward the second closed position, the floating seal assembly 37 moves the moving partition assembly 36 toward the first closed position. Thus, the axial direction DA can not be the up-down direction.

[0299] In Figure 40 In the ninth embodiment shown, the driving assembly 130 is replaced by an electromagnet, and the floating seal assembly 37 is configured to include ferromagnetic material. The electromagnet is provided, for example, on the inner side of the top wall 31A of the upper cover. The electromagnet is connected to a control circuit, and the control circuit is connected to the control device, so that the on-off of the electromagnet can be coordinated with the cooking process. For example, when the control software confirms that the cooking process enters the boiling-maintaining process, the control circuit is turned on, the electromagnet is powered on, and the floating seal assembly 37 is magnetically attracted to the second open position; when the control software confirms that the cooking process enters the heat-keeping process, the control circuit is turned off, the electromagnet is powered off, and the floating seal assembly 37 moves to the second closed position under the action of its own gravity. That is, the axial direction DA is the up-down direction. When the floating seal assembly 37 moves toward the second closed position, the floating seal assembly 37 moves the moving partition assembly 36 toward the first closed position.

[0300] The second to ninth embodiments introduce various ways of closing the first opening 41 by the moving partition assembly 36, and various ways of opening and closing the second opening 42 by the floating seal assembly 37. Those skilled in the art can reasonably combine different embodiments to more specifically control the movement of the moving partition assembly 36 and the floating seal assembly 37 according to specific needs. It can be understood that when the floating seal assembly 37 does not need to return to the second closed position by gravity, the axial direction of the second opening 42 can not be the up-down direction. When the floating seal assembly 37 does not need to move to the second open position by the action of the moving partition assembly 36, and the moving partition assembly 36 does not need to return to the first closed position by the action of the floating seal assembly 37, the moving partition assembly 36 and the floating seal assembly 37 can be independently provided.

[0301] In Figure 41 In the tenth embodiment shown, the second one-way valve 35 is configured as a gravity ball. The axial direction of the third opening 43 is the up-down direction, and the gravity ball sits in the third opening 43 by its own gravity to close the third opening 43, and can be lifted by the airflow of the airflow generating device 14 to open the third opening 43.

[0302] In Figure 42 In the eleventh embodiment shown, the second one-way valve 35 is configured as a pneumatic float. The axial direction of the third opening 43 is the up-down direction, and the pneumatic float sits in the third opening 43 by its own gravity to close the third opening 43, and can be lifted by the airflow of the airflow generating device 14 to open the third opening 43.

[0303] Of course, the air path integration device 30 can also be configured in other forms to integrate the air paths for suctioning negative pressure, discharging steam, and blowing cold air.
