[0050] Please see Figures 1 to 3 This invention provides a control method for a cooking pot 100, which includes a cooking cavity 10 and a vent 12. When the vent 12 is open, it connects the cooking cavity 10 and the outside of the cooking pot 100. The control method includes:

[0051] Step S101: While maintaining the first preset ventilation area at the exhaust port 12, control the cooking pot 100 to heat the cooking chamber 10;

[0052] Step S103: When boiling in the cooking chamber 10, the cooking pot 100 is controlled to run for a preset time according to the first cooking mode, with a preset heating power and a second preset ventilation area of ​​the exhaust port 12. The first cooking mode is related to the type of food in the cooking chamber 10, and the second preset ventilation area is smaller than the first preset ventilation area.

[0053] In the above-mentioned control method of cooking pot 100, the cooking mode can be selected according to the type of food in the cooking cavity 10 so that the cooking pot 100 cooks the food with the pressure of the corresponding mode. Therefore, the cooking pot 100 can be used to cook different foods and the cooking effect can be improved.

[0054] In cooking, to shorten cooking time, pressure can be applied to the cooking chamber to adopt a high-pressure cooking mode, increasing the cooking temperature and thus shortening the cooking time. However, in actual cooking, for ingredients that are difficult to cook thoroughly, such as meat and beans, cooking in a pressureless mode will require a longer cooking time, or pre-treatment of the ingredients is necessary. For example, beans need to be soaked for several hours before cooking. When using a high-pressure mode, easily cooked and difficult-to-cook ingredients need to be processed separately, or different ingredients should be added in multiple batches. Otherwise, easily cooked ingredients may become too soft, or difficult-to-cook ingredients may not be fully cooked, resulting in poor cooking outcomes. Furthermore, in high-pressure mode, the pressure increase and decrease require a longer time, ultimately leading to a longer cooking time.

[0055] To address the aforementioned issues, this invention provides a control method for a cooking pot 100. In addition to the pressureless mode and the pressurized mode of the cooking pot 100, an intermediate pressure mode is also provided, allowing users to select different cooking modes according to the type of food being cooked, and control the cooking pot 100 to operate at different pressures.

[0056] The cooking pot 100 has three cooking modes: a first cooking mode is a medium-pressure mode, a second cooking mode is a high-pressure mode, and a third cooking mode is a pressureless cooking mode. In the second cooking mode, the pressure inside the cooking chamber 10 can reach 70 kPa or higher. In the third cooking mode, the pressure inside the cooking chamber 10 is the same as or close to atmospheric pressure. In the first cooking mode, the pressure level inside the cooking chamber 10 is between the second and third cooking modes; for example, in the first cooking mode, the pressure inside the cooking chamber 10 can be 30 kPa, 40 kPa, or 50 kPa, or a pressure value between atmospheric pressure and 70 kPa above atmospheric pressure.

[0057] The cooking pot 100 has a cooking cavity 10 and a vent 12. When the vent 12 is open, it connects the cooking cavity 10 to the outside of the cooking pot 100. By controlling the ventilation area of ​​the vent 12, the area of ​​communication between the cooking cavity 10 and the outside of the cooking pot 100 can be controlled. That is, by controlling the ventilation area of ​​the vent 12 and the heating power of the cooking pot 100, the pressure inside the cooking cavity 10 can be controlled.

[0058] In the third cooking mode, the exhaust vent 12 maintains a third preset ventilation area. The third preset ventilation area is the ventilation area where the exhaust vent 12 is fully connected to the outside. When the cooking pot 100 operates within this third preset ventilation area, the pressure inside the cooking cavity 10 can be maintained at or near atmospheric pressure. Figure 2 As shown, the exhaust port 12 is in a state where it is fully connected to the outside world.

[0059] In the second cooking mode, the exhaust port 12 is closed. By heating the cooking chamber 10, the pressure inside the cooking chamber 10 can be rapidly increased, thereby achieving a high-pressure mode. Figure 1 As shown, the exhaust port 12 is completely closed.

[0060] In the first cooking mode, the exhaust port 12 maintains the second preset ventilation area, that is, the exhaust port 12 is partially connected to the outside. With different heating powers, the cooking pressure in the cooking cavity 10 can be maintained between atmospheric pressure and pressure values ​​exceeding atmospheric pressure by 70 kPa.

[0061] It is understandable that the second preset ventilation area is smaller than the first preset ventilation area, and the first preset ventilation area is less than or equal to the third preset ventilation area. That is, the cooking pot 100 can be heated to boiling under the third preset ventilation area, or it can be heated to boiling under the first preset ventilation area, which is between the second and third preset ventilation areas, and then switched to the first cooking mode. The cooking pot 100 is controlled to run for a preset time by the preset heating power and the second preset ventilation area of ​​the exhaust port.

[0062] The preset duration is the operating time of the cooking pot 100 when it operates at a certain heating power and the corresponding ventilation area of ​​the exhaust port 12, which allows the cooking cavity to reach a corresponding pressure. In other embodiments, a pressure sensor or a temperature sensor can be installed inside the cooking pot 100 to directly obtain the current pressure of the cooking cavity 10 or to obtain the corresponding current pressure based on the current temperature inside the cooking cavity 10.

[0063] In one example, the ventilation area of ​​the exhaust port 12 has four adjustable levels. At each level, the ventilation area connecting the cooking cavity 10 and the outside of the cooking pot 100 is controlled, as well as the heating power of the cooking pot 100 corresponding to the ventilation area of ​​the exhaust port 12, so that the cooking cavity 10 is maintained at an intermediate pressure level. The table below shows the corresponding values ​​of the ventilation area of ​​the exhaust port 12 and the heating power of the cooking pot 100 to maintain a pressure of 30 kPa in the cooking cavity 10 of the cooking pot 100.

[0064] Table 1. Comparison Table of Ventilation Area and Heating Power Matching Control

[0065] Current ventilation area / 3rd 1 / 4 1 / 2 3 / 4

[0066] Preset ventilation area

[0067] Matching power 800W 1000W 1400W

[0068] The current ventilation area of ​​the exhaust port 12 indicates that part of the exhaust port 12 is connected to the outside. The current ventilation area can be obtained by multiplying the ratio of the current ventilation area to the third preset ventilation area by the third preset ventilation area.

[0069] Please see Figure 4 In some embodiments, the preset duration includes a first preset duration and a second preset duration, and the second preset ventilation area includes the first stage ventilation area and the second stage ventilation area. Step S103 includes:

[0070] Step S1031: When boiling occurs in the cooking chamber 10, the cooking pot 100 is controlled to operate with a first heating power and a first stage ventilation area according to the first cooking mode.

[0071] Step S1033: After the cooking pot 100 is controlled to run for a first preset time with the first heating power and the first stage ventilation area, the cooking pot 100 is controlled to run for a second preset time with the second heating power and the second stage ventilation area. The second stage ventilation area is smaller than the first stage ventilation area, and the second heating power is smaller than the first heating power.

[0072] In this way, the cooking pot 100 can be controlled to operate at a preset cooking pressure in the first cooking mode.

[0073] Specifically, when the user selects the first cooking mode (taking the cooking pressure of the first cooking mode as 30kPa as an example), the heating device 24 of the cooking pot 100 is first controlled to work. After detecting boiling in the cooking cavity 10, it switches to the large boiling mode. At this time, the cooking pot 100 operates with a first heating power of 1400W and the first stage ventilation area of ​​the exhaust port 12 is 3 / 4 of the third preset ventilation area to achieve a large boiling state in the cooking cavity 10, so as to ensure the rolling effect of the food in the cooking cavity 10, the uniformity of cooking and the short cooking time.

[0074] After the first preset time is reached in the large boiling mode, the cooking pot 100 is switched to the small boiling mode. At this time, the cooking pot 100 operates with the second heating power of 800W and the second stage ventilation area of ​​the exhaust port 12 is 1 / 4 of the third preset ventilation area to achieve slow cooking over low heat, so as to ensure that the ingredients are thoroughly flavored and prevent the ingredients from being overcooked, lacking texture, or evaporating too much soup.

[0075] In the first cooking mode, by controlling the ventilation area and heating power of the exhaust port 12, while keeping the pressure inside the cooking chamber 10 at an intermediate pressure level, it is possible to keep the cooking chamber 10 in a boiling state at all times. This ensures that the cooking time is reduced under a certain cooking pressure, while also ensuring that the cooking chamber 10 is in a continuous boiling state, thereby ensuring the tumbling effect and cooking uniformity of the ingredients inside the cooking chamber 10.

[0076] Please see Figure 5 In some embodiments, the preset duration includes a first preset duration, a second preset duration, and a third preset duration; the second preset ventilation area includes the first-stage ventilation area, the second-stage ventilation area, and the third-stage ventilation area; step S103 includes:

[0077] Step S1035: When boiling occurs in the cooking chamber 10, the cooking pot 100 is controlled to operate with a first heating power and a first stage ventilation area according to the first cooking mode.

[0078] Step S1037: After the cooking pot 100 is operated for a first preset time with the first heating power and the first stage ventilation area, the cooking pot 100 is operated with the second heating power and the second stage ventilation area.

[0079] Step S1039: After the cooking pot 100 is controlled to run for a second preset time with the second heating power and the second stage ventilation area, the cooking pot 100 is controlled to run for a third preset time with the third heating power and the third stage ventilation area. Then, the cooking pot 100 is controlled to stop heating and the exhaust port 12 is closed. The third stage ventilation area is smaller than the second stage ventilation area, the second stage ventilation area is smaller than the first stage ventilation area, the third heating power is smaller than the second heating power, and the second heating power is smaller than the first heating power.

[0080] Thus, in the first cooking mode, the cooking chamber 10 can maintain a preset cooking pressure and cook under different cooking conditions.

[0081] Specifically, in the first cooking mode, the pressure inside the cooking chamber 10 is maintained between one atmosphere and 70 kPa above atmospheric pressure. At the same time, by controlling the ventilation area of ​​the exhaust port 12 and the heating power of the cooking device, different boiling states are maintained inside the cooking chamber 10, thereby ensuring the tumbling effect and cooking uniformity of the ingredients inside the cooking chamber 10.

[0082] Taking the cooking pressure of 30 kPa in the first cooking mode as an example, the cooking pot 100 is controlled by the first heating power (1400W), the second heating power (1000W), and the third heating power (800W), as well as the first stage ventilation area (3 / 4 of the third preset ventilation area), the second stage ventilation area (1 / 2 of the third preset ventilation area), and the third stage ventilation area (1 / 4 of the third preset ventilation area) in sequence. This allows the cooking pot 100 to switch from the large boiling mode to the small boiling mode while maintaining the cooking pressure of 30 kPa in the cooking chamber 10, thus realizing the function of the first cooking mode.

[0083] Please see Figure 6 In some implementations, the control method includes:

[0084] Step S105: After the cooking pot 100 has been running for a preset time with the second preset ventilation area and preset heating power, the cooking pot 100 is stopped from heating and the exhaust port is closed.

[0085] Thus, after the first cooking mode has been running for a preset time, the cooking pot 100 can stop working and close the exhaust port 12, entering the heat preservation and freshness preservation mode.

[0086] Specifically, in the first cooking mode, the cooking cavity 10 sequentially maintains a large boiling mode and a small boiling mode. After reaching the second preset time, the heating device 24 is controlled to stop working, and at the same time, the ventilation area of ​​the exhaust port 12 is adjusted to a fully closed state to prevent the water vapor generated during cooking from leaking out, so as to realize the water shrinkage and freshness preservation function in the cooking cavity 10.

[0087] In other embodiments, after the first cooking mode has been running for a preset time, the cooking pot 100 can be controlled to switch to the second or third cooking mode to continue cooking.

[0088] Please see Figure 7 In some implementations, the control method includes:

[0089] Step S107: In response to the mode selection operation, determine the cooking mode of the cooking pot 100;

[0090] Step S109: When the cooking mode is the second cooking mode, control the exhaust port 12 to close;

[0091] Step S111: When the cooking mode is the third cooking mode, control the exhaust port 12 to maintain the third preset ventilation area.

[0092] Thus, the cooking pot 100 has multiple cooking modes, allowing users to choose different cooking modes according to different ingredients.

[0093] Specifically, in the second cooking mode, the exhaust port 12 is completely closed. At this time, the heating device 24 controlling the cooking pot 100 is activated, causing the temperature and pressure inside the cooking chamber 10 to rise rapidly, thereby quickly reaching a high-pressure state inside the cooking chamber 10. The second cooking mode is suitable for cooking ingredients that are not easy to cook.

[0094] In the third cooking mode, the exhaust port 12 maintains a third preset ventilation area. The third preset ventilation area is the ventilation area where the exhaust port 12 is fully connected to the outside. When the cooking pot 100 operates under the third preset ventilation area, the pressure inside the cooking cavity 10 can be maintained at a level that is the same as or close to atmospheric pressure.

[0095] In one embodiment, the first cooking mode may include a first sub-mode and a second sub-mode, each sub-mode corresponding to a different preset pressure. For example, in the first sub-mode, the first preset cooking pressure is 30 kPa. By controlling the ventilation area and heating power of the exhaust port 12, the cooking pressure in the cooking chamber 10 is controlled to be maintained at around 30 kPa, and the cooking chamber 10 is controlled to sequentially switch between a large boiling mode and a small boiling mode.

[0096] In the second sub-mode, the second preset cooking pressure is 40 kPa. By controlling the ventilation area and heating power of the exhaust port 12, the cooking pressure in the cooking chamber 10 is controlled to be maintained at around 40 kPa, and the cooking chamber 10 is controlled to be in the large boiling mode and the small boiling mode in sequence.

[0097] In summary, in the first cooking mode, by controlling the ventilation area and heating power of the exhaust port 12, the pressure inside the cooking chamber 10 can be maintained at an intermediate pressure level while simultaneously keeping it in a boiling state. This ensures that cooking time is reduced under a certain cooking pressure, while maintaining a continuous boiling state within the cooking chamber 10, thus guaranteeing the tumbling effect and uniform cooking of the food. In the second cooking mode, the cooking chamber 10 can perform high-pressure cooking, allowing the food to cook quickly. In the third cooking mode, the cooking chamber 10 can perform pressureless cooking.

[0098] The control method of the cooking pot 100 described above can control the cooking pot 100 according to the cooking mode, so that the cooking pot 100 is suitable for different ingredients and cooking methods.

[0099] In some embodiments, the cooking pot 100 includes a pressure limiting device disposed at the vent 12. The pressure limiting device is used to block or open the vent 12 to maintain the pressure within the cooking cavity 10. The control method includes:

[0100] When the cooking mode is the second cooking mode, the exhaust port 12 is closed and the pressure limiting device is controlled to maintain the pressure inside the cooking chamber 10.

[0101] In this way, the pressure inside the cooking chamber 10 can be maintained at the cooking pressure corresponding to the second cooking mode by the pressure limiting device.

[0102] Specifically, when the exhaust port 12 is closed, the pressure inside the cooking cavity 10 is relatively high. To maintain the pressure inside the cooking cavity 10 at the cooking pressure corresponding to the second cooking mode, a pressure limiting device has a preset pressure limiting value. When the exhaust port 12 is closed, the pressure limiting device blocks the exhaust port 12, allowing the pressure inside the cooking cavity 10 to reach the pressure limiting value. When the pressure inside the cooking cavity 10 exceeds the pressure limiting value, the pressure limiting device opens the exhaust port 12, releasing the pressure inside the cooking cavity 10 and allowing the pressure inside the cooking cavity 10 to return to the pressure limiting value. Thus, the pressure inside the cooking cavity 10 can be maintained at the pressure limiting value set by the pressure limiting device.

[0103] In some implementations, in the first cooking mode and with the ventilation area remaining constant, the heating power of the cooking pot 100 is positively correlated with the pressure inside the cooking cavity 10.

[0104] Thus, in the first cooking mode and with the ventilation area unchanged, the cooking pressure can be adjusted by controlling the heating power of the cooking pot 100.

[0105] Specifically, in the first cooking mode and with the ventilation area unchanged, the cooking pressure can be adjusted by controlling the heating power of the cooking pot 100, so that the cooking pot 100 includes more cooking pressure options and is suitable for different ingredients and combinations of ingredients.

[0106] Table 2. Comparison Table of Ingredients, Cooking Pressure, Ventilation Area, and Heating Power Matching Control

[0107]

[0108] As shown in the table above, in the first cooking mode and with the ventilation area unchanged, different heating powers can be selected according to different ingredients and cooking needs, so that the cooking pressure in the cooking cavity 10 reaches the corresponding value, and the cooking pot 100 has multiple different intermediate pressures to cook food in the first cooking mode.

[0109] An embodiment of the present invention provides a control method for a cooking pot 100. The cooking pot 100 includes a cooking cavity 10 and a vent 12. When the vent 12 is open, it connects the cooking cavity 10 and the outside of the cooking pot 100. The cooking pot 100 includes a first cooking mode and a second cooking mode. The cooking pressure in the first cooking mode is lower than the cooking pressure in the second cooking mode. The control method includes:

[0110] When the cooking mode is the first cooking mode, the ventilation area of ​​the exhaust port 12 is controlled to make the pressure in the cooking chamber 10 reach the cooking pressure corresponding to the first cooking mode.

[0111] The control method of the cooking pot 100 described above has two cooking modes with different pressures. At the same time, the pressure in the cooking chamber 10 can be kept at the cooking pressure corresponding to the first cooking mode by controlling the ventilation area of ​​the exhaust port 12. Therefore, the cooking pot 100 can be used to cook different ingredients and the cooking effect can be improved.

[0112] Specifically, the first cooking mode of the cooking pot 100 is an intermediate pressure mode, and the second cooking mode is a high pressure mode. In the high pressure mode, the cooking pressure inside the cooking cavity 10 is greater than that in the intermediate pressure mode. When the vent 12 of the cooking pot 100 is open, it connects the cooking cavity 10 to the outside of the cooking pot 100. During the heating process of the cooking pot 100, the area connecting the cooking cavity 10 to the outside of the cooking pot 100 is related to the cooking pressure inside the cooking pot 100. Therefore, by controlling the ventilation area of ​​the vent 12, the pressure inside the cooking cavity 10 can be kept at the cooking pressure corresponding to the first cooking mode.

[0113] The first cooking mode can have multiple sub-modes, each with a corresponding ventilation area and cooking time. In the first cooking mode, the cooking chamber 10 can be cooked at different cooking pressures by adjusting the ventilation area and cooking time of the exhaust port 12. At the same time, the cooking pressure of each sub-mode in the first cooking mode is lower than the cooking pressure in the second cooking mode.

[0114] Please see Figure 8 This invention discloses a control method for a cooking pot 100, wherein the cooking pot 100 includes a cooking cavity 10 and a vent 12, the vent 12 connecting the cooking cavity 10 and the outside of the cooking pot 100 when venting; the control method includes:

[0115] Step S115: In response to the mode selection operation, determine the cooking mode of the cooking pot 100, the cooking mode includes a first cooking mode and a second cooking mode, the cooking pressure in the first cooking mode is less than the cooking pressure in the second cooking mode;

[0116] Step S117: According to the cooking mode, control the ventilation area of ​​the exhaust port 12 so that the pressure in the cooking chamber 10 reaches the cooking pressure corresponding to the cooking mode.

[0117] In the control method of the cooking pot 100 described above, the cooking pot 100 has two selectable cooking modes, and the two cooking modes correspond to different cooking pressures, which can make the cooking pot 100 suitable for cooking different ingredients and improve the cooking effect.

[0118] Specifically, when cooking with the cooking pot 100, the first step is to select a cooking mode. The cooking pot 100 has a first cooking mode and a second cooking mode. The first cooking mode is a medium pressure mode, and the second cooking mode is a high pressure mode.

[0119] After selecting the corresponding cooking mode, by adjusting the ventilation area of ​​the exhaust port 12, the cooking pot 100 can work under the ventilation area corresponding to the selected cooking mode, so that the cooking chamber 10 can reach the corresponding cooking pressure. In the first cooking mode, the ventilation area of ​​the exhaust port 12 is smaller than that of the exhaust port 12 in the second mode.

[0120] Furthermore, the cooking pot 100 also has a third cooking mode. The third cooking mode is a pressureless mode, in which the ventilation area of ​​the exhaust port 12 is maximized, so that the cooking pressure in the cooking chamber 10 is the same as or close to atmospheric pressure.

[0121] In this way, users can choose different cooking modes according to different ingredients, making the cooking pot 100 suitable for cooking different ingredients and improving the cooking effect.

[0122] Please see Figure 9 One embodiment of the present invention provides a control device 14, which includes a processor 16 and a memory 18. The memory 18 stores a computer program, which, when executed by the processor 16, implements the steps of the control method of the cooking pot 100 in any embodiment.

[0123] A cooking pot 100 according to an embodiment of the present invention includes the control device 14 described in the above embodiment. The cooking pot 100 includes a pot body 20, a pot lid 22 and a heating device 24. A cooking cavity 10 is provided inside the pot body 20. The pot lid 22 is used to seal the cooking cavity 10 when it is closed on the pot body 20. The heating device 24 is used to heat the cooking cavity 10. The control device 14 is electrically connected to the heating device 24 and is used to control the operation of the heating device 24.

[0124] Specifically, the control device 14 can be installed inside the cooking pot 100, which includes a pot body 20 and a lid 22. The pot body 20 has a cooking cavity 10, and the lid 22 is used to seal the cooking cavity 10 when it is closed on the pot body 20. The control device 14 can be located in the pot body 20, or the control device 14 can be located in the lid 22.

[0125] In one embodiment, the control device 14 is mounted on the pot body 20 and has a control panel for human-machine interaction, through which the user selects cooking modes, etc.

[0126] In some embodiments, the cooking pot 100 includes a pot body 20, a pot lid 22, and a heating device 24. The pot body 20 has a cooking cavity 10 inside. The pot lid 22 is used to seal the cooking cavity 10 when it is closed on the pot body 20. The heating device 24 is located at the bottom of the pot body 20. The control device 14 is electrically connected to the heating device 24 and is used to control the operation of the heating device 24.

[0127] In this way, the heating device 24 heats the cooking cavity 10, and the pressure inside the cooking cavity 10 can be adjusted in conjunction with the ventilation area of ​​the exhaust port 12.

[0128] Specifically, such as Figure 1 As shown, the heating device 24 is located at the bottom of the pot body 20, which facilitates the conduction of heat to the cooking cavity 10 to heat the food inside the cooking cavity 10. The control device 14 is electrically connected to the heating device 24 and matches the ventilation area of ​​the exhaust port 12 with the heating power according to the preset control program. It controls the heating device 24 to turn on or off according to different cooking modes, and to operate at different heating powers when it is on.

[0129] The heating device 24 includes, but is not limited to, at least one of a heating coil, a heating plate, and a heating tube.

[0130] In some embodiments, the cooking pot 100 includes a ventilation area adjustment device 26, which includes a drive member 27 and a baffle 28. The exhaust port 12 is disposed on the pot lid 22, and the baffle 28 is movably connected to the pot lid 22. The drive member 27 is used to drive the baffle 28 to move to adjust the ventilation area of ​​the exhaust port 12.

[0131] Thus, by controlling the movement of the baffle 28, the ventilation area adjustment device 26 can be controlled to adjust the ventilation area of ​​the exhaust port 12.

[0132] Specifically, the lid 22 of the cooking pot 100 is provided with a vent 12, which allows the cooking cavity 10 to communicate with the outside of the cooking pot 100 when the lid 22 is closed on the pot body 20. The ventilation area adjustment device 26 can control the area of ​​communication between the vent 12 and the outside of the cooking pot 100, thereby controlling the ventilation area of ​​the vent 12.

[0133] The ventilation area adjustment device 26 includes a drive member 27 and a baffle 28. The baffle 28 is movably disposed on one side of the exhaust port 12. The control device 14 can control the drive member 27 to drive the baffle 28 to move from one side of the exhaust port 12, thereby gradually reducing the ventilation area of ​​the exhaust port 12 and finally sealing the exhaust port 12, so that the cooking cavity 10 is completely sealed and isolated from the outside.

[0134] In one implementation, such as Figures 10 to 14As shown, the baffle 28 consists of four sector-shaped baffles 28 with an arc angle of 90°, and the exhaust port 12 is circular. The sector-shaped baffles 28 can overlap and can rotate around the center to unfold or overlap. Figure 10 As shown, when the ventilation area of ​​the exhaust port 12 is fully open, the baffle 28 moves to one side of the exhaust port 12, making the exhaust port 12 fully connected to the outside. Figure 11 As shown, when the exhaust port 12 has 1 / 4 of the ventilation area, the four overlapping fan-shaped baffles 28 move until the center of the fan-shaped baffles 28 coincides with the center of the exhaust port 12, thus closing 1 / 4 of the exhaust port 12. Figure 12 As shown, when the exhaust port 12 has half of the ventilation area, the overlapping second to fourth fan-shaped baffles 28 rotate 90° around the center, closing half of the exhaust port 12. Figure 13 As shown, when the exhaust port 12 has a ventilation area of ​​3 / 4, the overlapping third and fourth fan-shaped baffles 28 rotate 90° around the center, closing 3 / 4 of the exhaust port 12. Figure 14 As shown, when the ventilation area of ​​the exhaust port 12 is completely closed, the overlapping fourth fan-shaped baffle 28 rotates 90° around the center to completely seal the exhaust port 12.

[0135] In some embodiments, the cooking pot 100 includes a ventilation area adjustment device 26, which includes a drive member 27 and an adjustment rod. The exhaust port 12 is disposed on the pot lid 22. One end of the adjustment rod is tapered. The ventilation area of ​​the exhaust port 12 is adjusted by changing the distance that the tapered end of the adjustment rod extends into the exhaust port 12.

[0136] Thus, by controlling the movement of the adjusting rod, the ventilation area adjusting device 26 can be used to adjust the ventilation area of ​​the exhaust port 12.

[0137] Specifically, when the tapered end of the adjusting rod is fully inserted into the exhaust port 12, the exhaust port 12 can be closed. When the tapered end of the adjusting rod is completely away from the exhaust port 12, the ventilation area of ​​the exhaust port 12 can reach the third preset ventilation area. By controlling the movement of the adjusting rod and changing the distance at which the tapered end of the adjusting rod extends into the exhaust port 12, the ventilation area of ​​the exhaust port 12 can be adjusted.

[0138] The ventilation area of ​​the exhaust port 12 can be adjusted by installing a ventilation area adjustment device on the exhaust port 12, and adjusting the opening of the exhaust port 12 using the aforementioned ventilation area adjustment device. Alternatively, the ventilation area can be adjusted by adjusting the size of the exhaust port 12. For example, the pot lid 22 has an exhaust port 12 with a telescopic structure. Through the telescopic structure, the area of ​​the exhaust port 12 can be controlled, thereby adjusting the ventilation area of ​​the exhaust port 12 communicating with the outside.

[0139] In some embodiments, the cooking pot 100 includes a pressure limiting device installed at the vent 12 to block or open the vent 12.

[0140] In this way, the pressure inside the cooking cavity 10 can be maintained at the pressure limit value set by the pressure limiting device.

[0141] Specifically, the pressure limiting device has a preset pressure limit value. When the exhaust port 12 is closed, the pressure limiting device blocks the exhaust port 12, allowing the pressure inside the cooking chamber 10 to reach the pressure limit value. When the pressure inside the cooking chamber 10 exceeds the pressure limit value, the pressure limiting device opens the exhaust port 12, releasing the pressure inside the cooking chamber 10 and allowing the pressure inside the cooking chamber 10 to return to the pressure limit value. Thus, the pressure inside the cooking chamber 10 can be maintained at the pressure limit value set by the pressure limiting device. The pressure limiting device includes, but is not limited to, a weighted pressure limiting device, a steel ball pressure limiting device, etc. The aforementioned control device 14 and cooking pot 100 can select a cooking mode according to the type of food in the cooking chamber 10, so that the cooking pot 100 cooks the food at the pressure of the corresponding mode. Therefore, the cooking pot 100 can be used to cook different foods, while improving the cooking effect.

[0142] It should be noted that the above explanation of the implementation method and beneficial effects of the control method for the cooking pot 100 also applies to the control device 14 and the cooking pot 100 in the embodiments of this application. To avoid redundancy, they will not be elaborated in detail here.
