The opening end face of the cooking cavity includes an inner ring sealing area and an outer ring sealing area arranged from the inside to the outside, and an exhaust groove is provided in the outer ring sealing area.

[0005] In one embodiment, one end of the exhaust groove away from the inner ring sealing area penetrates through to the outer edge of the opening end face, and the flatness of the inner ring sealing area is less than that of the outer ring sealing area.

[0006] In one embodiment, the opening end face of the cooking cavity and the inner wall of the cooking cavity are transitioned through an arc surface.

[0007] In one embodiment, the opening of the cooking cavity is provided with a flanging, the flanging is arranged around the circumference of the cooking cavity, and the exhaust groove is provided in the flanging.

[0008] In one embodiment, at least two exhaust grooves are provided in the outer ring sealing area, and at least two exhaust grooves are arranged at intervals along the circumference of the opening of the cooking cavity.

[0009] The present application also proposes a cooking appliance, including:

[0010] An appliance main body, the appliance main body includes a pot body as described in any of the foregoing embodiments;

[0011] A cover body, the cover body is covered on the appliance main body; and

[0012] The sealing ring is provided on the cover body. The sealing ring is provided with a first sealing portion that is circumferentially arranged around the opening of the cooking cavity. When the cover body is closed on the appliance main body, the first sealing portion fits on the inner ring sealing area, and the first sealing portion also covers at least part of the exhaust groove.

[0013] In one embodiment, the outer edge of the first sealing portion does not exceed the end of the exhaust groove away from the inner ring sealing area.

[0014] In one embodiment, the sealing ring further includes a second sealing portion. The second sealing portion is circumferentially arranged around the cooking cavity. When the cover body is closed on the appliance main body, the second sealing portion is inserted into the opening of the cooking cavity, and the second sealing portion is connected to the first sealing portion;

[0015] The sealing ring further includes a connecting portion. The connecting portion is connected to the cover body, and the connecting portion is connected at the connection between the first sealing portion and the second sealing portion.

[0016] In one embodiment, the cooking appliance further includes an elastic member. The elastic member is provided between the cover body and the appliance main body to drive at least part of the cover body to lift in the initial open cover state.

[0017] In one embodiment, the cooking appliance further includes an air extraction assembly. The air extraction assembly can be communicated with the cooking cavity in the closed state of the cooking appliance to extract the gas in the cooking cavity;

[0019] The technical solution of the present utility model forms an inner ring sealing area and an outer ring sealing area arranged from the inside out on the opening end face of the pot body, and exhaust grooves are provided on the outer ring sealing area. With such a setting, when the pot body is applied to a cooking appliance and is closed with the lid, the sealing ring provided on the lid fits on the opening end face of the cooking cavity and fits on at least part of the area of the exhaust grooves in the inner ring sealing area and the outer ring sealing area, so that a better vacuum degree can be maintained in the cooking cavity when the cooking cavity is evacuated. As the cooking process progresses and the cooking cavity is in a negative pressure environment, when it is necessary to open the lid, at the initial lid-opening state, the lid is lifted upward and at least the sealing ring fitting on the inner ring sealing area rises with the lid, so as to form a gap between the sealing ring and the inner ring sealing area. Due to the action of the negative pressure inside the cooking cavity, the outer edge of the sealing ring still fits on the outer ring sealing area, but due to the setting of the exhaust grooves, the gap between the sealing ring and the inner ring sealing area can communicate with the outside through the exhaust grooves; that is, in the present application, when the sealing ring has not completely separated from the opening end face of the cooking cavity, the air outside the cooking cavity has already entered the cooking cavity in advance for pressure relief, breaking the suction force between the sealing ring and the appliance main body, so that the purpose of opening the lid more easily and quickly can be achieved.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0037] During the heating and cooking process of the cooking appliance, the gas in the cooking cavity expands due to heat and is discharged from the exhaust port. After the gas in the cooking cavity cools down, its volume decreases, and if there is no external gas supplement, it is easy to form a negative pressure environment in the cooking cavity. Or for some cooking appliances such as rice cookers with a vacuum pumping function, the cooking cavity can be actively evacuated to form a negative pressure environment. In a negative pressure environment, a suction cup effect is formed between the sealing ring provided on the lid and the pot body, and the sealing ring will tightly adhere to the pot body. When the user wants to open the lid immediately after pumping the vacuum, due to the internal negative pressure and the suction force between the sealing ring and the pot body, the cooking appliance cannot open the lid immediately. It is necessary to allow air to enter the cooking cavity to break the vacuum and separate the sealing ring from the pot body before the lid can be opened, resulting in a relatively long time-consuming lid opening process and affecting the user experience.

[0038] Based on the above problems, the present utility model proposes a pot body 12 that can enable the cooking appliance 100 to relieve pressure and open the lid more quickly.

[0039] Referring to Figures 1 to 8 , in an embodiment of the present application, a cooking cavity 121 is formed in the pot body 12. The opening end surface of the cooking cavity 121 includes an inner ring sealing area and an outer ring sealing area arranged from the inside to the outside, and an exhaust groove 122 is provided in the outer ring sealing area.

[0040] The pot body 12 proposed in this application is applied in the cooking appliance 100, and the cooking appliance 100 can be an electric rice cooker or a vacuum rice cooker provided with an air extraction component, etc. The cooking appliance 100 includes an appliance main body 1 and a lid body 2. The appliance main body 1 at least includes the pot body 12. The pot body 12 forms a cooking cavity 121 with an opening at the top. The pot body 12 can be a straight cylinder structure with an opening at the top, or as in the following embodiments, a flanging 123 also extends outside the opening at the top. The lid body 2 is arranged to be openable and closable. The lid body 2 can be rotatably connected to the appliance main body 1 or detachably connected to the appliance main body 1. A sealing ring 3 is arranged on the lid body 2. The sealing ring 3 is arranged to surround the circumference of the opening of the cooking cavity 121. The sealing ring 3 can include a connecting portion 33 and a first sealing portion 31. The connecting portion 33 is connected to the lid body 2. When the lid body 2 covers the appliance main body 1, the cooking cavity 121 is closed. At this time, the sealing ring 3 arranged on the lid body 2 is located at the opening edge of the cooking cavity 121. The sealing ring 3 has a certain elasticity and can be made of rubber, silica gel or silicone rubber. When the lid is closed, the first sealing portion 31 on the sealing ring 3 can fit on the opening end face of the cooking cavity 121 to improve the sealing performance of the cooking cavity 121 and reduce the risk of air leakage at the opening edge of the cooking cavity 121.

[0041] Among them, during the heating and cooking process of the cooking appliance 100, the gas in the cooking cavity 121 will expand due to heat and be discharged from the exhaust port. After the gas in the cooking cavity 121 cools down, its volume decreases. And if there is no external gas supplement, for example, if the cooking cavity 121 adopts a one-way exhaust valve, it is easy to form a negative pressure environment in the cooking cavity when the external gas cannot enter the cooking cavity 121 after the gas cools down. In addition, for the cooking appliance 100 provided with an air extraction component, the cooking cavity 121 can be actively evacuated to form a negative pressure environment in the cooking cavity 121, so that the cooking appliance 100 has the functions of vacuum cooking and low-pressure cooking. It should be noted that forming a negative pressure environment in the cooking cavity 121 through the air extraction component is only a function of the cooking appliance 100, and it does not mean that the vacuum evacuation operation needs to be performed every time the cooking appliance 100 is used for cooking. That is, the cooking appliance 100 can also adopt a cooking mode that does not require vacuum evacuation to form a negative pressure environment for cooking.

[0042] At the same time, in the embodiment of this application, it is defined that the opening end face of the pot body 12 has an inner ring sealing area and an outer ring sealing area arranged in sequence from the inside to the outside, and an exhaust groove 122 is opened in the outer ring sealing area, that is, the exhaust groove 122 is arranged at an interval from the inner edge of the opening end face of the cooking cavity 121. When the cooking appliance 100 is in the state of the lid being closed, as Figure 4 shown, the first sealing portion 31 of the sealing ring 3 fits on the opening end face and fits on the inner ring sealing area and the outer ring sealing area. The first sealing portion 31 covers at least part of the exhaust groove 122. Since the inner ring sealing area fits with the first sealing portion 31, the cooking cavity 121 is completely sealed. AsFigure 6 As shown, when it is necessary to open the lid, the locking between the lid body 2 and the appliance main body 1 can be released, making the lid body 2 movable. The lid body 2 is lifted upward by a certain distance against the suction force of the negative pressure inside the cooking cavity 121, so as to drive the sealing ring 3 to move upward. During this process, the sealing ring 3 deforms, and a part of the first sealing portion 31 that fits on the inner ring sealing area will rise with the lid body 2 and thus is spaced from the opening end face of the cooking cavity 121 to form a gap. Under the action of the negative pressure inside the cooking cavity 121, the outer edge of the first sealing portion 31 still fits on the outer ring sealing area, and this state is defined as the initial lid-opening state. In this state, the sealing ring 3 has not completely separated from the opening end face of the cooking cavity 121, and the outer edge of the first sealing portion 31 is still sucked on the outer ring sealing area. Due to the arrangement of the exhaust grooves 122 on the outer ring sealing area, the gap between the first sealing portion 31 and the inner ring sealing area can communicate with the external environment through the exhaust grooves 122, enabling the external gas to enter between the sealing ring 3 and the pot body 12 and then enter the cooking cavity 121, breaking the suction force between the sealing ring 3 and the pot body 12, so that the lid can be opened more easily and quickly.

[0043] Therefore, it can be understood that in the technical solution of the present utility model, an inner ring sealing area and an outer ring sealing area are arranged on the opening end face of the pot body 12 in a layout from the inside to the outside, and an exhaust groove 121 is opened on the outer ring sealing area. With such an arrangement, when the pot body 12 is applied to the cooking appliance 100 and the lid is closed with the lid body 2, the sealing ring 3 provided on the lid body 2 fits on the opening end face of the cooking cavity 121 and fits on at least part of the area of the exhaust groove 121 on the inner ring sealing area and the outer ring sealing area, so as to keep a good vacuum degree in the cooking cavity 121 when the cooking cavity 121 is evacuated. As the cooking process progresses, when the cooking cavity 121 is in a negative pressure environment and it is necessary to open the lid, at the initial lid-opening state, the lid body 2 is lifted upward and at least the sealing ring 3 that fits on the inner ring sealing area rises with the lid body 2 to form a gap between the sealing ring 3 and the inner ring sealing area. Due to the action of the negative pressure inside the cooking cavity 121, the sealing ring 3 still fits on the outer ring sealing area, but due to the arrangement of the exhaust groove 122, the gap 34 between the sealing ring 3 and the inner ring sealing area can communicate with the outside through the exhaust groove 122; that is, in this application, before the sealing ring 3 completely separates from the opening end face of the cooking cavity 121, the air outside the cooking cavity 121 has already entered the cooking cavity 121 in advance for pressure relief, breaking the suction force between the sealing ring 3 and the appliance main body 1, so that the purpose of opening the lid more easily and quickly can be achieved.

[0044] In some embodiments, the flatness of the inner ring sealing area is less than that of the outer ring sealing area. Thus, when the first sealing portion 31 is attached to the opening end face of the cooking cavity, the inner ring sealing area with a smaller flatness can be more closely attached to the first sealing portion 31, ensuring that a negative pressure environment can be formed in the cooking cavity 121. It should be noted that the flatness of the outer ring sealing area in this application refers to: when the groove wall of the exhaust groove 122 is used as the surface constituting the outer ring sealing area, the flatness of the outer ring sealing area.

[0045] Referring to Figure 4 、 Figures 6 to 8 In an embodiment, one end of the exhaust groove 122 away from the inner ring sealing area penetrates through to the outer edge of the opening end face.

[0046] With such a setting, it can further ensure that the exhaust groove 122 is reliably and quickly connected to the environment outside the cooking cavity 121. Thus, even when the first sealing portion 31 covers the exhaust groove 122, one end of the first exhaust groove 122 away from the inner ring sealing area will remain connected to the outside environment. Therefore, when it is necessary to open the lid, air outside the cooking cavity 121 can enter the gap between the first sealing portion 31 and the inner ring sealing area and then enter the cooking cavity 121 to relieve the pressure in the cooking cavity 121 and break the suction between the sealing ring 3 and the pot body 12, so that the lid can be opened more easily and quickly.

[0047] Please refer to Figure 4 In an embodiment, the opening end face of the cooking cavity 121 and the inner wall of the cooking cavity 121 are transitioned through an arc surface.

[0048] In some embodiments, the sealing ring 3 includes a first sealing portion 31 for attaching to the opening end face of the cooking cavity 121 and a second sealing portion 32 inserted into the cooking cavity 121. Making the opening end face of the cooking cavity 121 and the inner wall of the cooking cavity 121 transition through an arc surface can, when it is necessary to seal the cooking cavity 121, enable the first sealing portion 31 and the second sealing portion 32 to better attach to the pot body 12 to achieve a better sealing effect and prevent air leakage and pressure relief during the cooking process.

[0049] In certain embodiments, as Figure 6 shown, the sealing ring 3 further includes a second sealing portion 32 and a connecting portion 33. The second sealing portion 32 is arranged to surround the cooking cavity 121 in the circumferential direction, and the connecting portion 33 is connected to the lid body 12. The connecting portion 33 is connected at the connection between the first sealing portion 31 and the second sealing portion 32. In the initial lid-opening state, when the lid body 12 rises, the connecting portion 33 connected to the lid body 12 is pulled, and thus a cavity 34 is formed between the connection between the first sealing portion 31 and the second sealing portion 32 and the pot body 12.

[0050] Please refer to Figure 9 andFigure 10 , in one embodiment, a flanging 123 is provided at the opening of the cooking cavity 121. The flanging 123 is arranged to surround the circumference of the cooking cavity 121, and the exhaust groove 122 is formed in the flanging 123.

[0051] In this embodiment, the pot body 12 used to form the cooking cavity 121 in the appliance main body 1 extends outward with a flanging 123 at the opening edge. The setting of the flanging 123 increases the width of the opening end surface of the cooking cavity 121 in the opening radial direction, thereby increasing the contact area between the first sealing portion 31 and the opening end surface, and a better sealing effect can be achieved. In addition, increasing the area of the opening end surface of the cooking cavity 121 can provide a larger area for forming the exhaust groove 122 and can increase the size of the exhaust groove 122, which is convenient for processing the exhaust groove 122.

[0052] In one embodiment, at least two exhaust grooves 122 are formed in the opening end surface of the cooking cavity 121, and the at least two exhaust grooves 122 are arranged at intervals along the circumference of the opening of the cooking cavity 121.

[0053] With such a setting, when opening the lid after vacuum pumping, gas outside the cooking cavity 121 can be introduced through at least two exhaust grooves 122 in the initial lid-opening state, which can improve the speed of breaking the vacuum and relieving pressure in the cooking cavity 121, thereby improving the lid-opening speed and making the lid-opening process after vacuum pumping easier and faster.

[0054] Please refer to Figures 1 to 6 , this application also provides a cooking appliance 100, which includes:

[0055] An appliance main body 1, where the appliance main body 1 is provided with the pot body 12 proposed in any of the foregoing embodiments;

[0056] A lid body 2, the lid body 2 is covered on the appliance main body 1; and

[0057] A sealing ring 3, which is arranged on the lid body 2. The sealing ring 3 is provided with a first sealing portion 31 arranged to surround the circumference of the opening of the cooking cavity 121. When the lid body 2 is closed on the appliance main body 1, the first sealing portion 31 fits on the inner ring sealing area, and the first sealing portion 31 also covers at least part of the exhaust groove 122.

[0058] In the embodiments of the present application, the cooking appliance 100 can be a rice cooker or a vacuum rice cooker provided with an air extraction component. The cooking appliance 100 includes an appliance main body 1 and a lid 2. The appliance main body 1 at least includes a pot body 12, and the pot body 12 forms a cooking cavity 121 with an opening at the top. The pot body 12 can be a straight cylinder structure with an opening at the top, or as in the following embodiments, a flanging 123 also extends outside the opening at the top. The lid 2 is arranged to be openable and closable. The lid 2 can be rotatably connected to the appliance main body 1 or detachably connected to the appliance main body 1. A sealing ring 3 is arranged on the inner surface of the lid 2. The sealing ring 3 is arranged to surround the circumference of the opening of the cooking cavity 121. The sealing ring 3 can include a connecting portion 33 and a first sealing portion 31. The connecting portion 33 is connected to the lid 2. When the lid 2 is closed on the appliance main body 1, the cooking cavity 121 is closed. At this time, the sealing ring 3 arranged on the lid 2 is located at the opening edge of the cooking cavity 121. The sealing ring 3 has a certain elasticity and can be made of rubber, silica gel or silicone rubber. When the lid is closed, the first sealing portion 31 on the sealing ring 3 can be attached to the opening end face of the cooking cavity 121 to improve the airtight performance of the cooking cavity 121 and reduce the risk of air leakage at the opening edge of the cooking cavity 121.

[0059] Among them, during the heating and cooking process of the cooking appliance 100, the gas in the cooking cavity 121 will expand when heated and then be discharged from the exhaust port. After the gas in the cooking cavity 121 cools down, its volume decreases. And if there is no external gas supplement, for example, if the cooking cavity 121 adopts a one-way exhaust valve, it is easy to form a negative pressure environment in the cooking cavity when the outside gas cannot enter the cooking cavity 121 after the gas cools down. In addition, for the cooking appliance 100 provided with an air extraction component, the cooking cavity 121 can be actively evacuated to form a negative pressure environment in the cooking cavity 121, so that the cooking appliance 100 has the functions of vacuum cooking and low-pressure cooking. It should be noted that making the cooking cavity 121 form a negative pressure environment through the air extraction component is only a function of the cooking appliance 100, and it does not mean that the vacuum evacuation operation needs to be performed every time the cooking appliance 100 is used for cooking. That is to say, the cooking appliance 100 can also adopt a cooking mode that does not require vacuum evacuation to form a negative pressure environment for cooking.

[0060] Meanwhile, in the embodiment of the present application, it is defined that the opening end face of the pot body 12 has an inner ring sealing area and an outer ring sealing area arranged in sequence from inside to outside, and an exhaust groove 122 is opened in the outer ring sealing area, so that the exhaust groove 122 is arranged at an interval from the inner edge of the opening end face of the cooking cavity 121. When the cooking appliance 100 is in the closed lid state, the first sealing portion 31 of the sealing ring 3 fits on the opening end face, and fits on the inner ring sealing area and the outer ring sealing area. The first sealing portion 31 covers at least a part of the exhaust groove 122. Since the inner ring sealing area fits with the first sealing portion 31, the cooking cavity 121 is completely sealed. When it is necessary to open the lid, the locking between the lid body 2 and the appliance main body 1 can be released, so that the lid body 2 can move, and the lid body 2 can be lifted upward by a certain distance against the suction force of the negative pressure inside the cooking cavity 121 to drive the sealing ring 3 to move upward. During this process, the sealing ring 3 deforms, and a part of the first sealing portion 31 that fits on the inner ring sealing area will rise with the lid body 2 and thus be arranged at an interval from the opening end face of the cooking cavity 121 to form a gap. Under the action of the negative pressure inside the cooking cavity 121, the outer edge of the first sealing portion 31 still fits on the outer ring sealing area, and this state is defined as the initial lid-opening state. In this state, the sealing ring 3 has not completely separated from the opening end face of the cooking cavity 121, and the outer edge of the first sealing portion 31 is still sucked on the outer ring sealing area. Due to the arrangement of the exhaust groove 122 on the outer ring sealing area, the gap between the first sealing portion 31 and the inner ring sealing area can be communicated with the external environment through the exhaust groove 122, so that the external gas can enter between the sealing ring 3 and the pot body 12 and then enter the cooking cavity 121, destroying the suction force between the sealing ring 3 and the pot body 12, and thus the lid can be opened more easily and quickly.

[0061] In addition, since the cooking appliance 100 proposed in the present application adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.

[0062] Please refer to Figure 4 and Figure 6 , in an embodiment, the outer edge of the first sealing portion 31 does not exceed the end of the exhaust groove 122 away from the inner ring sealing area.

[0063] It can be understood that if the first sealing portion 31 completely covers the exhaust groove 122, and a part of the first sealing portion 31 fits on a partial area of the exhaust groove 122 and the outer edge of the opening end face. When the opening degree of the lid body 2 is small, the deformation amount of the sealing ring 3 is not enough to make the exhaust groove 122 break away from the coverage of the first sealing portion 31, and the exhaust groove 122 cannot communicate with the external environment, so it cannot communicate with the external environment in this opening state of the lid body 2. Furthermore, it is necessary for the lid body 2 to reach a larger opening degree, the deformation amount of the sealing ring 3 is large, and the first sealing portion 31 slides relative to the opening end face, so that the exhaust groove 122 can at least partially break away from the coverage of the first sealing portion 31. Based on this, in this embodiment, making the outer edge of the first sealing portion 31 not exceed the end of the exhaust groove 122 away from the cooking cavity 121 can ensure that when the lid needs to be opened after vacuum pumping, even if the opening degree is small, the exhaust groove 122 can be exposed outside the first sealing portion 31, and the exhaust groove 122 communicates with the external environment, so as to conduct the cooking cavity 121 and the external environment, and make the air in the external environment enter the cooking cavity 121 in advance to relieve the pressure of the cooking cavity 121, and destroy the suction force between the sealing ring 3 and the pot body 12, so that the lid can be opened more easily and quickly.

[0064] In an embodiment, the sealing ring 3 further includes a second sealing portion 32, the second sealing portion 32 is disposed around the circumference of the cooking cavity 121, and when the lid body 2 is closed on the appliance main body 1, the second sealing portion 32 is inserted into the opening of the cooking cavity 121.

[0065] In this embodiment, the sealing ring 3 includes a connected first sealing portion 31 and a second sealing portion 32, and both the first sealing portion 31 and the second sealing portion 32 are disposed around the circumference of the opening of the cooking cavity 121; when the cooking appliance 100 is in the closed lid state, the first sealing portion 31 is used to fit with the opening end face of the cooking cavity 121, and the second sealing portion 32 is inserted into the opening of the cooking space, which can make the second sealing portion 32 fit with the inner wall of the cooking cavity 121, or there can be a gap between the second sealing portion 32 and the inner wall of the cooking cavity 121. The setting of the second sealing portion 32 can make the sealing ring 3 have an offset in the closed lid state, and can improve the sealing performance and connection strength, so as to play a better sealing role when it is necessary to keep the cooking cavity 121 in a negative pressure state inside.

[0066] Please refer to Figure 2 , in an embodiment, the diameter of the second sealing portion 32 is smaller than the inner diameter of the cooking cavity 121, and when the cooking cavity 121 is in a vacuum state, the second sealing portion 32 is attached to the inner wall of the cooking cavity 121.

[0067] In this embodiment, the diameter of the second sealing portion 32 is smaller than that of the cooking cavity 121. When the cooking appliance 100 is in the closed lid state, the second sealing portion 32 is inserted into the opening of the cooking cavity 121 and is spaced from the inner wall of the cooking cavity 121. When the cooking cavity 121 is evacuated to form a negative pressure environment, under the action of the internal negative pressure, the second sealing portion 32 will adhere to the inner wall of the cooking cavity 121 to improve the sealing effect on the cooking cavity 121 and reduce the risk of vacuum leakage in the negative pressure state. When it is necessary to open the lid after evacuation, when the sealing ring 3 is lifted with the upper lid 21, since the second sealing portion 32 adheres to the inner wall of the cooking cavity 121 and the outer edge of the first sealing portion 31 adheres to the opening end face of the cooking cavity 121, when a part of the first sealing portion 31 is lifted and spaced from the opening end face of the cooking cavity 121, a cavity 34 is formed between the first sealing portion 31, the second sealing portion 32 and the pot body 12. The cavity 34 communicates with the outside through the exhaust groove 122. As the outside air enters the cavity 34, the second sealing portion 32 will also be separated from the inner wall of the cooking cavity 121 again, so that the air enters the cooking cavity 121 to play a role in pressure relief, so as to accelerate the separation of the sealing ring 3 from the pot body 12 and realize quick and easy opening of the lid.

[0068] In one embodiment, the cooking appliance 100 further includes an elastic member, and the elastic member is disposed between the lid body 2 and the appliance main body 1 to drive at least a part of the lid body 2 to lift in the initial lid-opening state.

[0069] In this embodiment, an elastic member is provided in the cooking appliance 100. The lid body 2 and the appliance main body 1 are locked to each other in the closed lid state, for example, by means of snap-fastening, plug pins, magnetic attraction, etc.; the elastic member is used to apply an upward thrust to the lid body 2 when unlocking the locking relationship between the appliance main body 1 and the lid body 2 during lid opening, so as to lift the lid body 2 to move the lid body 2 upward by a certain distance, thereby driving the sealing ring 3 to rise and deforming the sealing ring 3 so that a part of the structure of the first sealing portion 31 close to the opening of the cooking cavity 121 is spaced from the opening end face of the cooking cavity 121 to form a gap, and then pressure relief is carried out through the exhaust groove 122.

[0070] Among them, the elastic member can be a spring, and can be disposed at the locking position between the lid body 2 and the appliance main body 1. For example, the lid body 2 and the appliance main body 1 are snap-connected by a snap, and the spring can be disposed at the snap position to lift the lid body 2 when the snap connection is released or the lid body 2 is lifted by the spring driving the snap to reset; in some embodiments, the lid body 2 and the appliance main body 1 can be rotatably connected. At this time, the elastic member can be a torsion spring and is disposed at the rotational connection position between the lid body 2 and the appliance main body 1.

[0071] In one embodiment, the cooking appliance 100 further includes an air extraction assembly, and the air extraction assembly can communicate with the cooking cavity 121 in the closed lid state of the cooking appliance 100 to extract the gas in the cooking cavity 121.

[0072] In this embodiment, the appliance main body 100 has the function of actively evacuating the cooking cavity 121 by setting an air extraction assembly, and can actively perform a vacuum pumping process on the cooking cavity 121 to create a negative pressure environment in the cooking cavity 121, so that the cooking appliance 100 has the functions of vacuum cooking and low-pressure cooking. Among them, the air extraction assembly can be arranged on the cover body 2 or on the appliance main body 1, so that the air extraction assembly is communicated with the cooking cavity 121 in the state where the cooking appliance 100 is closed, so as to extract the gas in the cooking cavity, which can be used to avoid excessive pressure in the cooking cavity 121 and also create a negative pressure environment in the cooking cavity 121.

[0073] It should be noted that creating a negative pressure environment in the cooking cavity 121 through the air extraction assembly is only a function of the cooking appliance 100, and does not mean that a vacuum pumping operation needs to be performed every time the cooking appliance 100 is used for cooking. That is, the cooking appliance 100 can also adopt a cooking mode that does not require vacuum pumping to create a negative pressure environment for cooking.

[0074] Please refer to Figure 1 , in an embodiment, the appliance main body 1 further includes a pot body 11, a pan body 12 accommodated in the pot body 11; the cover body 2 includes an upper cover 21 and a movable cover plate 22 provided inside the upper cover 21, the sealing ring 3 is provided on the movable cover plate 22, the upper cover 21 is buckled on the pot body 11 in the closed state, and the movable cover plate 22 covers the pan body 12.

[0075] In this embodiment, the appliance main body 1 includes a pot body 11 and a pan body 12 arranged inside the pot body 11. The pan body 12 forms a cooking cavity 121, and the pot body 11 can be used for heat insulation to prevent the heated high-temperature pan body 12 from scalding the user. The cover body 2 includes an upper cover 21 and a movable cover plate 22. The upper cover 21 can be mutually covered and connected with the pot body 11. The movable cover plate 22 is arranged on the side of the upper cover 21 facing the pot body 11 and is detachably connected to the upper cover 21. The sealing ring 3 is arranged on the movable cover plate 22. With such an arrangement, the movable cover plate 22 can be used for heat insulation, and the sealing ring 3 and the movable cover plate 22 can be detached from the cover body 2 for easy cleaning.

[0076] In some embodiments, the cooking pot body 11 is provided with a movable buckle, and the upper cover 21 is provided with a corresponding fixed buckle. The cooking pot body 11 is further provided with an opening button. The opening button touches the movable buckle to disengage from the fixed buckle so that the upper cover 21 and the cooking pot body 11 are opened. The appliance main body 1 may further be provided with a torsion spring. One end of the torsion spring is fixed on the cooking pot body 11, and the other end is fixed on the upper cover 21. When the movable buckle disengages from the fixed buckle, the torsion spring will drive the upper cover 21 to flip, so that one end of the upper cover 21 disengages from the cooking pot body 11 and rises, and then drives the sealing ring 3 to rise, causing the sealing ring 3 to deform, so that a part of the first sealing portion 31 close to the opening of the cooking cavity 121 is spaced apart from the end face of the opening of the cooking cavity 121 to form a gap, and then pressure is relieved through the exhaust groove 122.
