[0042] See also Figure 1 to Figure 2 The embodiment of the utility model provides a cooking device 100. The cooking device 100 includes a pot cover assembly 10 and a pot body 20. The pot cover assembly 10 includes a pot cover 11 and an oxygen supplement device 12, and the oxygen supplement device 12 is arranged on the pot cover 11. The pot body 20 is connected to the pot cover 11, a cooking cavity 21 is formed in the pot body 20, and the pot cover 11 covers the cooking cavity 21. The oxygen supplement device 12 is configured to transport oxygen outside the cooking cavity 21 into the cooking cavity 21.

[0043] The above-mentioned cooking device 100, by setting an oxygen replenishing device 12 on the pot cover 11, enables the cooking cavity 21 of the cooking device 100 to achieve timely oxygen replenishment in a pressurized cooking environment to ensure that the food in the cooking cavity 21 fully undergoes the Maillard reaction, thereby improving the aroma and color of the food, and has good practicality.

[0044] Specifically, in one embodiment, the cooking device 100 may be a pressure cooker or other pressure cooking appliances, which is not specifically limited herein.

[0045] In one embodiment, the shape of the pot cover assembly 10 matches the shape of the pot body 20, and the pot cover assembly 10 is arranged above the pot body 20, and they can be covered and connected with each other, so that the cooking device 100 forms a relatively closed cooking environment.

[0046] In one embodiment, the shape of the pot body 20 includes but is not limited to a jar shape, so that the cooking device 100 is strong, stable, simple and beautiful.

[0047] In one embodiment, the oxygen supplement device 12 can be a pump-type oxygen supply device, an electrolysis-type oxygen supply device, or other types of oxygen supply equipment, which are not specifically limited here.

[0048] That is, the oxygen supplement device 12 can supply oxygen by filtering the air, or by electrolysis, for example, including but not limited to electrolysis of water or carbon dioxide gas, etc., or by other methods, which are not specifically limited here.

[0049] In one embodiment, the oxygen supplementing device 12 is disposed on the pot cover 11 so that the oxygen supplementing device 12 is located in a space outside the cooking cavity 21. Under the condition of ensuring the cooking space, the oxygen supplementing device 12 can be ensured to work safely.

[0050] In one embodiment, the oxygen supply device 12 may be disposed on the inner side of the pot cover 11 , such as the interlayer cavity portion of the pot cover 11 , so as to be stably placed and ensure the oxygen supply efficiency of the cooking cavity 21 .

[0051] In other embodiments, the oxygen supplement device 12 may also be arranged on the outside of the pot cover 11, for example, welded or bolted to the top or side of the pot cover 11, or may be arranged at other positions of the pot cover 11 to ensure that the oxygen supplement device 12 stably supplies oxygen, without specific limitation herein.

[0052] The oxygen provided by the oxygen supplementation device 12 of the utility model embodiment can be pure oxygen (for example, oxygen is generated by electrolyzing water) or clean air (for example, dust is removed from the air using filter cotton). It only needs to ensure the oxygen supply and no specific restrictions are made here.

[0053] In one embodiment, the oxygen supplementing device 12 can be connected to the cooking cavity 21 through a pipeline, and timely replenish the oxygen required for the cooking process to the cooking cavity 21, so that the food in the cooking cavity 21 can fully undergo the Maillard reaction, that is, the food can undergo a caramelization reaction to form a brown product with a unique flavor, thereby improving the appearance and taste of the food, and further improving the user experience.

[0054] For example, in one example, when cooking braised pork in a pressurized environment, the cooking device 100 can supply appropriate oxygen to the cooking chamber 21 through the oxygen supply device 12 to ensure that the cooked braised pork has the characteristics of bright red color, unique flavor, and tenderness, thereby improving the user experience.

[0055] In some embodiments, the pot cover 11 is provided with a containing cavity 111 , and the oxygen supplementing device 12 is located in the containing cavity 111 .

[0056] In this way, the stability of the oxygen supplementation device 12 is improved, thereby ensuring that the oxygen supplementation device 12 works normally and has good safety.

[0057] Specifically, in one embodiment, the pot cover 11 is provided with a accommodating cavity 111. It can be understood that the pot cover 11 has a built-in accommodating cavity 21 to ensure the stability of the oxygen supplementing device 12, so that the oxygen supplementing device 12 is stably placed in the accommodating cavity 111, thereby ensuring the normal operation of the oxygen supplementing device 12.

[0058] It can be understood that the oxygen supply device 12 is located in the accommodating cavity 111 and above the pot body 20, and can be used to supply oxygen to the cooking cavity 21 so that the oxygen is mixed with the heated rising water vapor, and the food is fully subjected to non-enzymatic browning reaction under the flow of gas, thereby improving the cooking flavor, color and cooking taste of the food.

[0059] In some embodiments, the pot cover 11 is provided with an opening (not shown), and the opening is connected to the accommodating cavity 111 .

[0060] In this way, a continuous source of oxygen-producing raw materials is guaranteed, thereby ensuring sufficient oxygen supply.

[0061] Specifically, Figure 1As shown, in one embodiment, the pot cover 11 is provided with an opening (not shown) so that the accommodating cavity 111 is connected with the external space, thereby ensuring that oxygen-generating raw materials such as water or air can be continuously supplemented to the oxygen supply device 12, so as to form oxygen with higher purity after processing and continuously supplied to the cooking cavity 21, thereby ensuring the cooking effect of the cooking equipment 100 in a pressurized aerobic environment.

[0062] It can be understood that the accommodating chamber 111 is connected to the external space through an opening (not shown), which can ensure that the oxygen supplementing device 12 has sufficient oxygen-producing raw materials to be supplemented, thereby ensuring that the oxygen supplementing device 12 works normally to provide a sufficient amount of oxygen.

[0063] In one embodiment, an opening (not shown) may be provided on the top of the pot cover 11 and adjacent to the oxygen supply device 12 to increase the supply speed of the oxygen-generating raw material, thereby ensuring the oxygen supply speed of the cooking cavity 21 .

[0064] In other embodiments, the opening (not shown) may also be set at a position of the pot cover 11 away from the oxygen supply device 12, and the supply speed of the oxygen-producing raw material may be increased by a suction power device. For example, the suction power device may be a pump to ensure the oxygen supply speed of the cooking chamber 21. No specific limitation is made here.

[0065] It is worth noting that the accommodating cavity 111 and the cooking cavity 21 are separated from each other, which can prevent the oxygen-generating raw materials from directly entering the cooking cavity 21 through an opening (not shown), prevent dust, impurities, etc. from contaminating the food, thereby improving the safety of food cooking.

[0066] In some embodiments, the pot cover 11 includes an inner cover 112, the inner cover 112 faces the cooking cavity 21, the oxygen supplementing device 12 includes an oxygen supply body 121 and a delivery pipe 122, the delivery pipe 122 is connected to the oxygen supply body 121, the oxygen supply body 121 is located on the side of the inner cover 112 away from the cooking cavity 21, one end of the delivery pipe 122 is connected to the oxygen supply body 121, and the other end passes through the inner cover 112 and is at least partially located in the cooking cavity 21.

[0067] In this way, it is ensured that the oxygen generated by the oxygen supplementing device 12 is introduced into the cooking cavity 21 in time, thereby ensuring the oxygen supply efficiency.

[0068] Specifically, in one embodiment, Figure 1 As shown, the inner cover 112 is disposed between the accommodating cavity 111 and the cooking cavity 21 , so that the accommodating cavity 111 and the cooking cavity 21 are separated, thereby ensuring that the cooking process of the food and the oxygen production process work independently, thereby maintaining the pressurized cooking environment of the cooking cavity 21 .

[0069] In one embodiment, the oxygen supply body 121 may be a sealed oxygen production space or impurity removal space, and may produce oxygen by chemical electrolysis or by physical filtration and dust removal to ensure the cleanliness and sufficient supply of oxygen.

[0070] It is worth noting that for physical dust removal, the oxygen supply body 121 includes but is not limited to using filter cotton to remove dust and impurities from the air, and may also use molecular sieves and other methods to remove dust and impurities, and no specific restrictions are made here.

[0071] In one embodiment, the delivery pipe 122 passes through the inner cover 112 and is at least partially located in the cooking cavity 21, which can ensure that the oxygen supply body 121 and the cooking cavity 21 are connected to increase the oxygen supply speed and oxygen supply amount in the cooking cavity 21, thereby ensuring that the food undergoes sufficient Maillard reaction, thereby improving the color and flavor of the food.

[0072] In one embodiment, the delivery tube 122 and the inner cover 112 can be connected by interference fit or fixed by adhesive to ensure that the accommodating cavity 111 and the cooking cavity 21 are separated from each other, thereby ensuring the safety of the food.

[0073] In one embodiment, the delivery tube 122 includes but is not limited to a connecting tube made of silicone material, and may also be a tube made of other materials to ensure safe and rapid delivery of oxygen, which is not specifically limited herein.

[0074] In one embodiment, the oxygen supply body 121 is located on the side of the inner cover 112 away from the cooking cavity 21. On the one hand, it can reduce the heat transfer of the cooking cavity 21 to ensure a safe oxygen production environment. On the other hand, it can quickly obtain the source of oxygen production raw materials from the external environment through an opening (not shown), thereby increasing the oxygen supply speed.

[0075] In certain embodiments, the oxygen supply body 121 includes at least one of a pump or an electrolysis device.

[0076] In this way, a sufficient oxygen supply is ensured, thereby improving the cooking effect of the cooking device 100 in a pressurized cooking environment.

[0077] Specifically, in one embodiment, the oxygen supply body 121 can be a pump, which can supply clean air to the cooking cavity 21 by drawing air into the oxygen supply device 12 and filtering out dust and other impurities in the air with filter cotton, thereby ensuring that the food in the cooking cavity 21 fully undergoes the Maillard reaction, thereby ensuring that the food has a unique flavor and a bright red color.

[0078] In another embodiment, the oxygen supply body 121 can be an electrolytic device, such as a sealed electrolytic cell, which can draw water or carbon dioxide gas into the oxygen supply device 12 and produce oxygen by electrolysis, thereby supplying oxygen with higher purity to the cooking cavity 21, thereby ensuring that the food in the cooking cavity 21 fully undergoes the Maillard reaction, thereby ensuring that the food has a unique flavor and bright red color.

[0079] In summary, the oxygen supply body 121 includes at least one of a pump or an electrolysis device, which can be used to provide oxygen to the cooking chamber 21 to ensure the Maillard reaction of the food, thereby improving the aroma and color of the food in a pressurized aerobic environment, thereby ensuring the cooking effect of the cooking device 100.

[0080] In some embodiments, the cooking device 100 includes a detection device 30, which is disposed on the pot cover 11 and is at least partially located in the cooking cavity 21, and the detection device 30 is configured to detect the pressure of the cooking cavity 21, and the oxygen supplementation device 12 is configured to operate when the pressure of the cooking cavity 21 reaches a preset pressure.

[0081] In this way, the food in the cooking cavity 21 is cooked in a pressurized and aerobic environment, thereby ensuring the aroma and color of the food.

[0082] Specifically, in one embodiment, the detection device 30 may be a pressure sensor, which can be used to detect pressure data in the cooking cavity 21 .

[0083] It can be understood that the detection device 30 can detect the pressure data of the cooking cavity 21 in real time to determine the cooking state of the cooking device 100, thereby ensuring that the food is in a pressurized cooking environment and supplying oxygen to the cooking cavity 21 in a timely manner, thereby ensuring the cooking effect of the food.

[0084] That is, the detection device 30 detects the pressure of the cooking cavity 21 to determine the oxygen supply time according to the type of food, thereby improving the reaction efficiency and oxygen utilization rate of the Maillard reaction and reducing energy waste.

[0085] In one embodiment, the detection device 30 can be set on the inner cover 112 and at least partially located in the cooking cavity 21 to ensure the real-time and accuracy of the data detected by the detection device 30 in the cooking cavity 21, thereby improving the working efficiency of the oxygen supplementation device 12 and saving energy and protecting the environment.

[0086] It can be understood that the detection device 30 can be partially located in the cooking cavity 21, or can be completely located in the cooking cavity 21 to ensure the accuracy of data detection, and no specific limitation is made here.

[0087] In one embodiment, the preset pressure may be a preset pressure that the cooking cavity 21 needs to reach when the oxygen supplementation device 12 is turned on, and may vary according to the type of food.

[0088] That is, the preset pressure is the critical pressure at which the food needs to be supplemented with oxygen to maintain the Maillard reaction, which can be used to determine the opening time of the oxygen supplement device 12, thereby ensuring the cooking effect of the food in a pressurized aerobic environment and reducing oxygen consumption and energy consumption.

[0089] It can be understood that after the food is put into the cooking device 100, the cooking cavity 21 works in a pressurized environment, so that the pressure of the cooking cavity 21 increases as the cooking temperature increases, and oxygen is continuously consumed for cooking.

[0090] That is, when the pressure of the cooking chamber 21 reaches the preset pressure, the cooking device 100 needs to add oxygen to the cooking chamber 21 to maintain the aerobic reaction of the food, that is, the Maillard reaction. At this time, the oxygen supply device 12 is turned on to meet the oxygen supply demand of the food, thereby ensuring the effect of the Maillard reaction and further ensuring the aroma and color of the food.

[0091] It is worth noting that the oxygen supplement device 12 can be started at different stages of the cooking process to obtain different functions and cooking effects, and no specific limitation is made here.

[0092] For example, when cooking food in a closed environment, the oxygen supplement device 12 can be activated during the frying process before the cooking chamber 21 is pressurized to increase oxygen, thereby enhancing the Maillard reaction during the frying process.

[0093] In some embodiments, the preset pressure is greater than or equal to 30 KPa.

[0094] In this way, it is ensured that the cooking device 100 replenishes oxygen in time, thereby achieving the purpose of improving oxygen utilization and saving energy.

[0095] Specifically, in one embodiment, the preset pressure may be a preset pressure that the cooking cavity 21 needs to reach when the oxygen supplementation device 12 is turned on, and may vary according to the type of food.

[0096] For example, in one example, the pressure required for the Maillard reaction of bean ingredients (such as unsoaked soybeans or soy beans) is relatively high, so it is necessary to start the oxygen supplement device 12 when the preset pressure is 70 KPa. At this time, the bean ingredients are oxygenated so that the Maillard reaction of the bean ingredients is more effective, with better color and aroma.

[0097] It is understandable that some easy-to-cook ingredients (such as green leafy vegetables such as leeks) require a relatively small pressure for the Maillard reaction to occur. In this case, a good cooking effect can be obtained by simply starting the oxygen supplement device 12 at a preset pressure of 30 KPa.

[0098] In summary, the preset pressure is greater than or equal to 30 KPa to ensure that the food in the cooking chamber 21 is replenished with oxygen in a timely manner, thereby ensuring a uniform and sufficient Maillard reaction, and further ensuring the cooking aroma and color.

[0099] The upper limit of the preset pressure can be determined based on empirical values ​​and is not specifically limited here. The preset pressure can be greater than or equal to 30 KPa.

[0100] For example, in some examples, the value of the preset pressure may be 30 KPa, 33 KPa, 45 KPa, 57 KPa, 66 KPa or 70 KPa, etc.

[0101] In some embodiments, when the pressure of the cooking cavity 21 reaches a preset pressure, the operating time of the oxygen supplementing device 12 is selected from the range of [5 min, 30 min].

[0102] In this way, while ensuring the maturity of the ingredients, the aroma and color of the ingredients can be guaranteed by using an appropriate cooking time, thus ensuring that the taste of the ingredients is better.

[0103] Specifically, in one embodiment, the oxygen supplementing device 12 should select a suitable working time to reduce energy waste while ensuring the maturity of the food and the cooking effect.

[0104] In one embodiment, the working time of the oxygen supplementing device 12 is selected from the range of [5min, 30min] to ensure that the food in the cooking cavity 21 undergoes a sufficient Maillard reaction, thereby improving the color and aroma of the food, and further ensuring the cooking effect of the food in a pressurized aerobic environment.

[0105] For example, in some examples, the working time of the oxygen supplementation device 12 can be 5 minutes, 7 minutes, 10 minutes, 15 minutes, 20 minutes, 27 minutes, 30 minutes or other values ​​between 5 minutes and 30 minutes, and no specific limitation is made here.

[0106] In one embodiment, when the pressure of the cooking chamber 21 reaches a preset pressure, the oxygen supply device 12 works for less than 5 minutes, resulting in insufficient oxygen supply, which in turn causes insufficient Maillard reaction of the food, resulting in less aroma and poorer color of the cooked food.

[0107] In another embodiment, when the pressure of the cooking chamber 21 reaches a preset pressure, the oxygen supplementing device 12 works for more than 30 minutes, resulting in excessive oxygen supplementation, which not only wastes energy but also causes the food to be overcooked, produce a burnt smell, a darker color, and a poor taste.

[0108] In one embodiment, when the working time of the oxygen supplementing device 12 is in the range of [5 min, 30 min], the oxygen supplementing device 12 can supply oxygen continuously or intermittently to ensure that the Maillard reaction of the food material fully occurs and the food material is mature.

[0109] In some embodiments, the cooking device 100 includes a heating element 40, which is disposed at the bottom of the cooking cavity 21 and located in the pot body 20. When the pressure of the cooking cavity 21 reaches a preset pressure, the heating element 40 and the oxygen supplementing device 12 work simultaneously for at least a period of time.

[0110] In this way, it is ensured that the cooking device 100 performs a sufficient Maillard reaction while improving energy utilization.

[0111] Specifically, in one embodiment, Figure 1 As shown, the heating elements 40 are disposed on both sides of the bottom of the cooking cavity 21 so that the cooking cavity 21 is heated evenly, thereby ensuring the heating uniformity of the cooking device 100 .

[0112] In one embodiment, when the pressure of the cooking chamber 21 reaches a preset pressure, it can be understood that the cooking chamber 21 is at a critical pressure where oxygen needs to be supplemented to maintain the Maillard reaction, so that the oxygen supplementation device 12 starts working to maintain an aerobic cooking environment, thereby ensuring that the food undergoes a sufficient Maillard reaction and further ensuring the cooking effect of the food.

[0113] In one embodiment, when the pressure of the cooking cavity 21 reaches a preset pressure, the oxygen supplementing device 12 can work intermittently to maintain the food in the cooking cavity 21 in a pressurized and oxygenated state, thereby ensuring the maturity of the food.

[0114] For example, in one example, the oxygen supply device 12 can intermittently supply oxygen by supplying oxygen for 2 minutes, pausing the oxygen supply for 1 minute, and then supplying oxygen for 2 minutes to ensure that the food in the cooking chamber 21 undergoes a sufficient Maillard reaction until the opening time range of the oxygen supply device 12 is reached [5 minutes, 30 minutes].

[0115] It is understood that for different ingredients, the cooking device 100 has different cooking times, so that the opening time of the oxygen supplement device 12 also has a corresponding value, which can be determined according to actual cooking experience. The above embodiments are only for understanding purposes and should not limit the actual application of the embodiments of the utility model.

[0116] In another embodiment, when the pressure of the cooking cavity 21 reaches a preset pressure, the oxygen supplementing device 12 may also continue to work to maintain the food in the cooking cavity 21 in a pressurized and oxygenated state, thereby ensuring the maturity of the food, which is not specifically limited here.

[0117] That is, the heating element 40 and the oxygen supply device 12 work simultaneously for at least a period of time to ensure that the cooking chamber 21 maintains a pressurized aerobic cooking environment, thereby ensuring that the food undergoes a full Maillard reaction.

[0118] See also Figure 1 and Figure 2 In some embodiments, the pot cover 11 is provided with an exhaust hole 113 and an exhaust device 114, and the exhaust device 114 is configured to close and open the exhaust hole 113. When the exhaust hole 113 is opened, the cooking cavity 21 is connected to the external space of the cooking cavity 21 through the exhaust hole 113. When the exhaust hole 113 is closed, the cooking cavity 21 is separated from the external space of the cooking cavity 21.

[0119] In this way, the cooking needs of users are met, thereby ensuring the aroma and color of cooking ingredients.

[0120] Specifically, in one embodiment, the exhaust hole 113 may be provided on the pot cover 11 to ensure that the cooking cavity 21 and the external space of the cooking cavity 21 can be selectively connected to meet the actual needs of users for multi-functional cooking.

[0121] It can be understood that when the cooking device 100 is in the pressurized cooking mode, the cooking cavity 21 can be isolated from the external space of the cooking cavity 21 by closing the exhaust hole 113, thereby forming a pressurized cooking environment.

[0122] When the cooking device 100 turns on the pressure-free cooking mode, the exhaust hole 113 can be opened so that the cooking cavity 21 is connected to the external space of the cooking cavity 21, thereby forming a pressure-free cooking environment.

[0123] In some embodiments, the exhaust device 114 includes a power device 115 and a valve 116 . The power device 115 is connected to the valve 116 . The power device 115 is configured to drive the valve 116 to move so as to adjust the opening of the exhaust hole 113 .

[0124] In this way, the power device 115 can drive the valve 116 to move, thereby adjusting the opening of the exhaust hole 113 .

[0125] Specifically, the power device 115 can be used to drive the valve 116 to cooperate with the exhaust hole 113, so as to adjust the opening of the exhaust hole 113. Specifically, the cooking device 100 can be used in a pressure-free adjustable cooking mode, in which case the opening of the exhaust hole 113 is adjustable. The adjustment range of the opening can be [0,100]. When the opening is 0, the exhaust hole 113 is closed. When the opening is 100, the exhaust hole 113 is fully open. The corresponding relationship between the movement stroke of the valve 116 and the opening of the exhaust hole 113 can be pre-calibrated and stored, so that the opening of the exhaust hole 113 can be controlled by driving the movement stroke of the valve 116 by the power device 115.

[0126] In one example, the power device 115 may be a stepping motor, a knob device, or other driving devices, which are not specifically limited herein.

[0127] In some embodiments, the side wall of the exhaust hole 113 is provided with an opening 117 , which is connected to the exhaust hole 113 , and the valve 116 penetrates into the exhaust hole 113 or exits the exhaust hole 113 through the opening 117 when moving.

[0128] In this way, the valve 116 can control the opening of the exhaust hole 113 by opening a hole in the side wall of the exhaust hole 113, which is beneficial to reducing the thickness of the pot cover 11.

[0129] Specifically, the side wall of the exhaust hole 113 is provided with an opening 117, the exhaust device 114 can be arranged on the circumferential aspect of the exhaust hole 113, and the valve 116 can enter and exit the exhaust hole 113 from the side of the exhaust hole 113 through the opening 117, thereby avoiding the exhaust device 114 occupying the space in the height direction of the pot cover 11, which is beneficial to reducing the thickness of the pot cover 11.

[0130] In one embodiment, the exhaust hole 113 and the accommodating cavity 111 are independently arranged to ensure that the cooking device 100 can achieve a multifunctional cooking process.

[0131] In one embodiment, the cooking apparatus 100 may be used in a pressurized aerobic cooking mode.

[0132] For example, when the cooking device 100 performs pressurized cooking, the embodiment of the utility model can transport oxygen outside the cooking cavity 21 to the cooking cavity 21 through the oxygen supplementing device 12 to ensure that the food can fully undergo the Maillard reaction in a pressurized aerobic environment, thereby improving the aroma and color of the food, and having good practicality.

[0133] That is, in the embodiment of the present invention, when the cooking cavity 21 reaches a preset pressure, the oxygen supply device 12 starts to supply oxygen into the cooking cavity 21, thereby ensuring the cooking effect.

[0134] In detail, the cooking steps may be: putting food into the cooking cavity 21, starting the pressurized aerobic cooking function, and making the heating element 40 work. At this time, the exhaust device 114 starts working to close the exhaust hole 113 (the exhaust hole 113 may also be adjusted to be small, as long as it does not affect the pressurized aerobic environment). When the detection device 30 detects that the pressure in the cooking cavity 21 reaches the preset pressure, the food in the cooking cavity 21 is in an oxygen-deficient state, and the oxygen supplement device 12 starts working to provide oxygen to the cooking cavity 21 to ensure that the food in the cooking cavity 21 is aerobically cooked, so that the cooking cavity 21 maintains a pressurized aerobic state and the oxygen supplement device 12 works for a time range of [5min, 30min], thereby stopping the heating element 40 and the oxygen supplement device 12, and opening the exhaust hole 113 to complete the pressurized aerobic cooking process.

[0135] It is worth noting that, in another embodiment, the cooking device 100 can be used in a pressure-free adjustable cooking mode, in which case the opening of the exhaust hole 113 is adjustable and the oxygen supplement device 12 may not work temporarily.

[0136] It can be understood that when the cooking device 100 performs pressureless cooking, the embodiment of the utility model can adjust the opening of the exhaust hole 113 to maintain the pressure in the cooking cavity 21 consistent with the pressure of the external environment, so as to ensure that the food is cooked in a pressureless environment, thereby avoiding excessive water loss of the food and improving the cooking taste.

[0137] For example, when cooking wooden barrel rice, the opening of the exhaust hole 113 can be appropriately adjusted according to the boiling degree of water in the cooking cavity 21 (such as large boiling, small boiling, and stewing rice stage) to avoid excessive water loss, which makes the surface of the food dry and yellow.

[0138] In detail, the cooking steps may be: putting food into the cooking cavity 21, starting the pressure-free adjustable cooking function, making the heating element 40 work, and then the exhaust device 114 starts to work to open the exhaust hole 113 at the maximum opening, so that the cooking cavity 21 enters the boiling stage. When the detection device 30 detects that the water in the cooking cavity 21 reaches a large boiling state, the corresponding cooking time is maintained to ensure that the food is cooked quickly, and then the heating power of the heating element 40 is reduced to maintain the water in the cooking cavity 21 in a small boiling state, and the corresponding opening of the exhaust hole 113 (for example, 3 / 4 opening, 1 / 2 opening or 1 / 4 opening, etc.) is adjusted to ensure a pressure-free environment and avoid excessive water loss. After cooking in a small boiling state for a certain period of time, the cooking cavity 21 begins to enter the stewing stage (for example, stewing rice), and the exhaust hole 113 is closed at this time and the rice stewing process without water loss is performed for a predetermined time. After the rice stewing process is completed, the heating element 40 stops working and the exhaust hole 113 is opened (for example, the exhaust hole 113 is fully opened), thereby completing the pressure-free adjustable cooking process.

[0139] That is, the cooking device 100 can adopt a pressure-free adjustable cooking function for cooking, which can solve the problem of dry ingredients due to excessive water loss, making the cooked ingredients fresh, juicy and with good water retention, thereby improving the cooking taste of the ingredients in a pressure-free cooking environment and achieving a good cooking effect.
