[0043] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0044] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In the description of the embodiments of the present application, "multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0045] As part of the creative concept of the present application, before describing the embodiments of the present application, it is necessary to analyze the reasons why the related technology cannot meet the requirements of different foods for different cooking modes, and obtain the technical solution of the embodiments of the present application through reasonable analysis.

[0046] In the related art, an exhaust passage is usually provided to adjust the air pressure in the cooking cavity. However, during the heating process, even if the exhaust passage is opened to the maximum, it is still difficult to reduce the air pressure in the cooking cavity to a level close to the external atmospheric pressure. In the process of cooking food, the soup in the cooking cavity often needs to boil violently, which requires the air pressure in the cooking cavity to be as low as possible. The best situation is to make the air pressure in the cooking cavity basically consistent with the outside. Therefore, cooking utensils such as pressure cookers in the related art are difficult to meet the cooking needs of this type of food.

[0047] The present application embodiment provides a cooking utensil, see Figure 1 and Figure 2 The cooking appliance includes a cooking body 1 and an actuator. The cooking body 1 has a cooking cavity 1a and a first exhaust channel 1b and a second exhaust channel 1c connected to the cooking cavity 1a. When the first exhaust channel 1b is opened, the cooking cavity 1a can be kept in a non-pressurized state during the heating process. When the second exhaust channel 1c is opened, the cooking cavity 1a can be pressurized during the heating process. The actuator is used to switch the switch state of the first exhaust channel 1b and the switch state of the second exhaust channel 1c. The switching of the switch state of the first exhaust channel 1b and the switching of the switch state of the second exhaust channel 1c do not interfere with each other.

[0048] In this embodiment, the cooking appliance has a first exhaust channel 1b and a second exhaust channel 1c connected to the cooking cavity 1a. When the first exhaust channel 1b is opened, the cooking cavity 1a can be kept in a pressure-free state during the heating process, and the food is cooked in a pressure-free state, so that the soup in the cooking cavity 1a can boil quickly. When the first exhaust channel 1b is closed and the second exhaust channel 1c is opened, the cooking cavity 1a can be kept in a pressurized state, the food can be cooked quickly, and the nutrients in the food can be dissolved in the soup. By controlling the opening and closing of the first exhaust channel 1b and the second exhaust channel 1c, the cooking cavity 1a can be switched from a pressure-free state to a pressurized state, and the cooking cavity 1a can also be switched from a pressurized state to a pressure-free state. The implementation scheme of the present application can solve the problem of the demand for different cooking modes for different foods.

[0049] It should be noted that the pressure-free state means that the air pressure in the cooking cavity 1a is substantially equal to the external air pressure. The external air pressure refers to the atmospheric pressure corresponding to the external environment.

[0050] It should be noted that the pressure build-up refers to the pressure in the cooking cavity 1a rising above the atmospheric pressure during the heating process.

[0051] It should be noted that non-interference means that the first exhaust channel 1b and the second exhaust channel 1c do not affect each other in structure, and does not mean that they cannot be coordinated in control. The first exhaust channel 1b and the second exhaust channel 1c can be controlled to be opened or closed together, or can be controlled to be opened or closed separately.

[0052] In one embodiment, the actuator includes two pressure relief valves, each of which has two states: open and closed. One of the pressure relief valves is used to open or close the first exhaust passage 1b, and the other pressure relief valve is used to open or close the second exhaust passage 1c.

[0053] In one embodiment, please refer to Figure 1 and Figure 2The cooking appliance further comprises an emulsifying device 2 arranged on the cooking body 1, and the emulsifying device 2 is used for emulsifying the soup in the cooking cavity 1a.

[0054] In this embodiment, the cooking appliance has an emulsifying device 2 capable of emulsifying the soup, so as to make the soup in the cooking cavity 1a more fragrant.

[0055] It is understandable that when cooking with cooking equipment, especially meat food, during the cooking process, fat and protein in the meat food will dissolve, and the fat and protein will combine with the soup or float on the surface of the soup.

[0056] It is understood that protein has hydrophilic groups and lipophilic groups, and fat particles are continuously wrapped in the lipophilic groups of proteins, so that the proteins wrapped with fat are dissolved in water, increasing the thickness of the soup, and achieving the effect of emulsifying the soup. Alternatively, the particle size of the fat particles is smaller than the particle size that the fat particles can dissolve in water, so that the fat particles are dissolved in water, and the effect of emulsifying the soup is achieved.

[0057] It can be understood that the fat and protein in the soup are squeezed and collided when the soup passes through the emulsification hole 2a of the emulsification device 2. The fat can better wrap the protein during the squeezing and collision process, thereby achieving an emulsification effect.

[0058] In one embodiment, the emulsifying device 2 is formed with an emulsifying hole 2a communicating with the cooking cavity 1a, and the emulsifying hole 2a is used for emulsifying the soup.

[0068] The present application also provides a cooking method. Figure 3 , the cooking method is applied to the above-mentioned cooking utensil, and the cooking method comprises:

[0069] Step S1: heating the cooking cavity 1a at a first power when the first exhaust passage 1b is closed;

[0070] Step S2: when the cooking cavity 1a is heated to a first switching condition, the first exhaust passage 1b is switched to an open state;

[0071] Step S3: When the state of the cooking cavity 1a is switched from the state corresponding to the first switching condition when the cooking cavity 1a is heated to the pressureless state, the soup is driven to flow through the emulsifying device 2 with the first exhaust passage 1b opened.

[0072] In this embodiment, the cooking method heats the cooking cavity 1a at a first power when the first exhaust channel 1b is closed. The air pressure in the cooking cavity 1a will continue to increase with time, and the fat in the food can quickly precipitate from the food and float on the surface of the soup. When the cooking cavity 1a is heated to the state corresponding to the first switching condition and switched to a pressure-free state, the food in the cooking cavity 1a can continue to be cooked in the pressure-free state. In the pressure-free state, the soup can be driven to flow through the emulsifying device 2 to emulsify the soup. Since the soup is heated to the first switching condition when the first exhaust channel 1b is closed, the fat in the food has been precipitated in large quantities. In the pressure-free cooking stage, the fat can be emulsified quickly, which increases the emulsification efficiency of the emulsifying device 2 so that the soup can quickly become fragrant.

[0073] In one embodiment, the step of heating the cooking cavity 1a at a first power when the first exhaust passage 1b is closed includes: controlling the second exhaust passage 1c to remain closed.

[0074] In one embodiment, please refer to Figure 4 When the cooking cavity 1a is heated to the first switching condition, before the first exhaust passage 1b is switched to the open state, the cooking method further includes:

[0075] Step S4: When the cooking cavity 1a is heated to a preset state, the cooking cavity 1a is heated with a second power to keep the cooking cavity 1a in the preset state, and the first switching condition is that the time for which the cooking cavity 1a remains in the preset state reaches a first preset time.

[0076] In this embodiment, before the cooking chamber 1a is heated to the first switching condition, the cooking chamber 1a is first heated to a preset state and maintained for a first preset time. During the process of the food being kept in the cooking chamber 1a for the first preset time, fat is continuously precipitated from the food into the soup. After the cooking chamber 1a is kept in the preset state for the first preset time, the fat in the food is basically all precipitated into the soup, waiting for the emulsification device 2 to emulsify the fat in the subsequent steps.

[0077] In one embodiment, please refer to Figure 4 The preset state is that the pressure in the cooking cavity 1a reaches a first preset pressure, and the second exhaust passage 1c is in an open state during the process of heating the cooking cavity 1a with a second power to keep the cooking cavity 1a in the preset state.

[0078] In this embodiment, the second exhaust passage 1c is in an open state during the process of heating the cooking cavity 1a with the second power to keep the cooking cavity 1a in a preset state. This control method is simple and can ensure that the cooking cavity 1a is kept in a preset state, and the air pressure will not continue to rise to cause a safety accident.

[0079] It should be noted that the preset state is that the pressure in the cooking cavity 1a reaches a first preset pressure, and during the process of heating the cooking cavity 1a with a second power to keep the cooking cavity 1a in the preset state, the second exhaust channel 1c is in an open state, including opening the second exhaust channel 1c and keeping it open before the cooking cavity 1a is heated to the first preset pressure; and opening the second exhaust channel 1c and keeping it open after the cooking cavity 1a is heated to the first preset pressure.

[0080] It is understandable that the present embodiment is not limited to keeping the second exhaust passage 1c in an open state to maintain the air pressure in the cooking cavity 1a. In one embodiment, the air pressure in the cooking cavity 1a is stabilized by adjusting the heating power of the cooking cavity 1a.

[0081] In one embodiment, please refer to Figure 3 The cooking method further includes: when the pressure in the cooking cavity 1a is greater than or equal to a second preset pressure, opening the first exhaust passage 1b, and the second preset pressure is greater than the first preset pressure.

[0082] In this embodiment, when the air pressure in the cooking cavity 1a is greater than the second preset pressure, the first exhaust passage 1b is opened to release the air pressure in the cooking cavity 1a, so as to quickly reduce the air pressure in the cooking cavity 1a, thereby ensuring that the cooking appliance will not explode due to excessive pressure, thereby protecting the personal safety of the user.

[0083] In one embodiment, please refer to Figure 4 When the first exhaust channel 1b is opened, the power required to heat the cooking cavity 1a to drive the soup to flow through the emulsifying device 2 is the third power, and both the first power and the third power are greater than the second power.

[0084] In this embodiment, the third power and the first power are both greater than the second power. The second power is used to keep the air pressure in the cooking cavity 1a at a preset state, without the need for excessive power for heating. If the power is too large, the air pressure in the cooking cavity 1a may change too quickly and be difficult to control. The first power is used to quickly increase the air pressure in the cooking cavity 1a, thereby shortening the cooking time and increasing the cooking efficiency. The third power is used to drive the soup to flow through the emulsifying device 2. The soup needs to expand in volume when flowing through the emulsifying device 2, so a larger heating power can quickly increase the temperature of the soup, thereby achieving boiling and volume expansion.

[0085] In one embodiment, the first power is 1400W-1800W, the second power is 800W-1000W, and the third power is 1400W-1800W.

[0086] In this embodiment, the value ranges of the first power and the third power are both 1400 W-1800 W, and the value range of the second power is 800 W-1000 W. Any power value selected within the value range of the first power, the second power and the third power can satisfy the cooking method.

[0087] Exemplarily, the value of the first power may be 1400W, 1500W, 1600W, 1700W or 1800W.

[0088] Exemplarily, the value of the second power may be 800W, 900W or 1000W.

[0089] Exemplarily, the value of the third power may be 1400W, 1500W, 1600W, 1700W or 1800W.

[0090] In one embodiment, please refer to Figure 5 When the cooking cavity 1a is heated to the first switching condition and the first exhaust passage 1b is switched to an open state, the cooking method further includes:

[0091] Step S20: when the pressure of the cooking chamber 1a drops to the atmospheric pressure, it is determined that the state of the cooking chamber 1a is a pressure-free state;

[0092] Step S21: or, when the temperature of the cooking chamber 1a drops to the boiling point of water under atmospheric pressure, it is determined that the state of the cooking chamber 1a is a pressureless state;

[0093] Step S22: Or, when the pressure of the cooking cavity 1a remains unchanged, it is determined that the state of the cooking cavity 1a is a pressure-free state.

[0094] In this embodiment, the pressure or temperature in the cooking cavity 1a is used to determine whether the device in the cooking cavity 1a reaches a pressure-free state, so that the state in the cooking cavity 1a can be accurately determined, thereby performing pressure-free cooking.

[0095] It should be noted that when the pressure of the cooking cavity 1a drops to the atmospheric pressure, it means that the absolute pressure of the cooking cavity 1a is substantially equal to the atmospheric pressure, and the relative pressure between the gas pressure in the cooking cavity 1a and the atmospheric pressure is 0.

[0096] In one embodiment, the cooking appliance includes a pressure sensor or a temperature sensor to monitor the state in the cooking cavity 1 a , and the pressure sensor or the temperature sensor is installed on the cooking body 1 .

[0097] It should be noted that the pressure in the cooking cavity 1a drops to the atmospheric pressure refers to the atmospheric pressure of the environment in which the cooking appliance is currently located, and the pressure in the cooking cavity 1a only needs to be approximately equal to the atmospheric pressure.

[0098] It should be noted that the temperature in the cooking cavity 1a can represent the temperature of the soup, and the temperature sensor monitoring the temperature in the cooking cavity 1a or the temperature of the soup can represent the temperature of the cooking cavity 1a.

[0099] It is to be understood that the embodiment of the present application is not limited to judging that the state of the cooking chamber 1a is a pressureless state when the temperature of the cooking chamber 1a drops to the boiling point of water under atmospheric pressure. In one embodiment, the temperature in the cooking chamber 1a is converted into pressure by using the temperature of the cooking chamber 1a and the Clapeyron equation, and then compared with the atmospheric pressure. When the converted pressure of the cooking chamber 1a is approximately equal to the atmospheric pressure, it is determined that the state of the cooking chamber 1a is a pressureless state.

[0100] In one embodiment, please refer to Figure 6 Before heating the cooking cavity 1a at the first power in a state where the first exhaust passage 1b is closed, the cooking method further comprises:

[0101] Step S5 : heating the cooking cavity 1 a at a fourth power while the first exhaust passage 1 b is open to allow the soup to flow toward the emulsifying device 2 .

[0102] In this embodiment, before heating at the first power with the first exhaust passage 1b closed, the first exhaust passage 1b is opened, and the cooking chamber 1a is heated at the fourth power to allow the soup to flow to the emulsifying device 2.
