Description

Technical Field

[0001] The present invention belongs to the technical field of cooking devices, and in particular relates to a cooking device with an open high-pressure inner cover structure and a control method thereof. Background Art

[0002] To ensure that cooking equipment can form a high-pressure sealed space and fully heat food, the lid and pot body of the cooking equipment must have a good seal. The principle is: under high-pressure cooking conditions, the seal is squeezed by the high-pressure gas and tightly adheres to the inner wall of the pot body, reliably sealing the pot body. Therefore, a seal with a lower hardness is generally used to seal the lid and pot body. However, when opening the lid, the seal and the pot body are too tightly adhered, making it difficult to open the lid from the outside of the cooking equipment, and the lid and pot body cannot be separated, causing inconvenience. If a seal with a higher hardness is used, the seal is less likely to deform under pressure and adhere to the inner wall of the pot body. After the pressure is released, it can easily separate from the inner wall of the pot body, but this will greatly reduce the reliability of the seal. In addition, even with a seal with a higher hardness, it is impossible to completely avoid the situation where the lid and pot body cannot be separated.

[0003] In order to solve the problem that the seals on the pot body and the pot lid stick together and make the pot lid difficult to open, there is an urgent need for a cooking device that can facilitate the opening of the pot lid and has good sealing performance. Summary of the Invention

[0004] In order to solve at least one of the above-mentioned technical problems, the present invention provides a cooking device with an openable high-pressure inner cover structure and a control method thereof.

[0005] According to one aspect of the present invention, a cooking device with an openable high-pressure inner lid structure is disclosed, characterized in that it includes an inner pot, an outer pot, a stirring tool, and an inner pot lid, wherein the inner pot is connected to the bottom of the outer pot, the inner pot lid is disposed on the inner pot, and the stirring tool is rotatably connected to the inner pot, and the stirring tool is provided with a protruding structure;

[0006] The protruding structure is used to push open the inner pot cover when cooking is completed and the stirring tool moves to a preset position, so as to separate the inner pot cover from the inner pot.

[0007] In some possible implementations, during the cooking process, when the rotation angle range of the stirring tool is within a first angle range, the protruding structure and the inner pot cover are in a non-contact state.

[0008] In some possible implementations, when cooking is completed, the stirring tool performs a reciprocating motion within a second angle range; the first angle range is smaller than the second angle range, and the preset position is the position where the stirring tool is at the limit value of the second angle range.

[0009] In some possible implementations, the stirring tool is arc-shaped, and a fixing hole is provided at the end of the stirring tool. The fixing hole is rotatably connected to the inner wall of the inner pot via a connecting structure.

[0010] In some possible implementations, the bottom of the stirring tool contacts the bottom of the inner pot, and the protruding structure is provided on the bottom plane of the stirring tool;

[0011] The bottom plane is the plane where the bottom of the stirring tool is located, and the bottom plane is perpendicular to the end plane of the stirring tool. The end plane is the plane where the end of the stirring tool contacts the inner wall of the inner pot.

[0012] In some possible implementations, the protruding structure is obtained by extending the bottom of the stirring tool toward both sides.

[0013] In some possible implementations, the cooking device further includes an outer pot cover, which is disposed on the outer pot and is used to press and lock the inner pot cover.

[0014] According to another aspect of the present invention, a method for controlling a cooking device having a high-pressure inner cover structure is disclosed. When cooking is completed, the method comprises:

[0015] sending a cover-opening signal to the stirring tool, so that the stirring tool performs a reciprocating motion within a second angle range in response to the cover-opening signal;

[0016] And when the stirring tool moves to a preset position, the raised structure on the stirring tool pushes the inner pot cover open, and the inner pot cover is separated from the inner pot.

[0017] In some possible implementations, the cooking device further includes an outer pot cover, the outer pot cover and the outer pot forming a closed structure, the closed structure pressing the inner pot cover. Before sending the cover-opening signal to the stirring tool, the method further includes:

[0018] sending a pressure relief signal to the cooking device, so that the cooking device relieves pressure in response to the pressure relief signal;

[0019] After the pressure relief is completed, an unlocking signal is sent to the outer pot cover, so that the outer pot cover is unlocked and moves upward by a preset distance in response to the unlocking signal.

[0020] In some possible implementations, during the cooking process, the method further comprises:

[0021] A stirring signal is sent to the stirring tool, so that the stirring tool performs reciprocating motion within a first angle range in response to the stirring signal.

[0022] The technical solution provided by the embodiment of the present invention has the following technical effects: by arranging a protruding structure on the stirring tool, when cooking is completed, the stirring tool can push open the inner pot cover through the protruding structure when it moves to a preset position, thereby preventing the seal from being tightly adhered to the pot wall of the inner pot and unable to be separated, thereby making it easy to remove the inner pot cover from the inner pot, saving manpower for taking the inner pot cover, and improving the convenience and practicality of the cooking device; there is no need to reduce the elasticity of the seal, nor to rely on other complex components or external equipment to assist in opening the cover, which reduces the restrictions on the seal material and the difficulty of seal processing, reduces the dependence on auxiliary equipment, and thus saves processing and manufacturing costs.

It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of the present invention and are not intended to limit the embodiments of the present invention.

[0041] For devices that heat food by means of a high-pressure sealing structure formed between a pot body and a pot lid, after cooking is completed and the pressure is released, it is often impossible to separate the pot lid and the pot body due to the tight fit between the seal 22 and the inner pot. It takes a lot of manpower to open the pot lid, which causes great inconvenience to use. If the hardness of the seal 22 is reduced, the degree of fit between the seal 22 and the pot body can be reduced, but at the same time it will cause low airtightness of the device and poor heating effect. Therefore, an embodiment of the present invention provides a cooking device with a pot lid that can be opened from the inside, without sacrificing the airtightness of the cooking device, and the pot lid and the pot body can be easily separated when cooking is completed.

[0042] like Figure 1 、 Figure 3As shown, an embodiment of the present invention provides a cooking device with an open high-pressure inner cover structure, and the cooking device can be subdivided into a cooking part, a fixing part, a heating part and an appearance part. The cooking part is the part directly related to the cooking process, including a stirring tool 1, an inner pot 2, an inner pot cover 21, and a driving device 8. The position adjustment part is the part for fixing or adjusting the position of the inner pot, including a bracket 4, an outer pot 3, an outer pot cover 31, a base 6, a guide rail 91, and a guide rail 92. The heating part is the part for supplying heat to the inner pot, including a heating module 5. The appearance part includes a door structure 12, a chassis 10, a bottom cover 13, and a cooking device shell 7.

[0043] In some possible embodiments, the cooking device includes an inner pot 2, an outer pot 3, a stirring tool 1 and an inner pot cover 21, the inner pot 2 is connected to the bottom of the outer pot 3, the inner pot cover 21 is arranged on the inner pot 2, the stirring tool 1 is rotatably connected to the inner pot 2, and the stirring tool 1 is provided with a protruding structure 11.

[0044] The protruding structure 11 is used to push open the inner pot cover 21 when cooking is completed and the stirring tool 1 moves to a preset position, so as to separate the inner pot cover 21 from the inner pot. The protruding structure 11 includes a first protruding structure 111 and a second protruding structure 112.

[0045] Optionally, the inner pot 2 is connected to the bottom of the outer pot 3 through a connecting structure, so as to fix the position of the inner pot 2 when it needs to be fixed. The connecting structure can be a snap-fit ​​structure, and the bottom of the outside of the inner pot 2 and the bottom of the inside of the outer pot 3 are respectively provided with mutually matching snap-fit ​​structures, so that the inner pot 2 and the outer pot 3 can be fixed. For example, a groove is provided at the bottom of the inside of the outer pot 3, and a protrusion matching the shape of the groove is provided at the bottom of the outside of the inner pot 2. Similarly, the inner pot 2 and the outer pot 3 can also be connected by other means, which will not be repeated here.

[0046] The embodiment of the present invention provides a protruding structure on the stirring tool. When cooking is completed, the stirring tool moves to a preset position and can push the inner pot cover open through the protruding structure, thereby preventing the seal from being tightly adhered to the pot wall of the inner pot and unable to be separated. As a result, the inner pot cover is easy to remove from the inner pot, saving manpower for removing the inner pot cover and improving the convenience and practicality of the cooking device. There is no need to reduce the elasticity of the seal, nor to rely on other complex components or external equipment to assist in opening the cover, which reduces the restrictions on the seal material and the difficulty of seal processing, reduces the dependence on auxiliary equipment, and thus saves processing and manufacturing costs.

[0047] See also Figure 6 and Figure 7 , as shown in the figure, Figure 7 Therefore Figure 6 The BB shown is a cross-sectional structure diagram generated by the cross section. Figure 6、 Figure 7 It can be seen that the stirring tool 1 has different shapes at different angles during the stirring process, such as Figure 7 As shown, the stirring tool rotates within a first angle range α and does not contact the inner pot cover 21. In some possible embodiments, during the cooking process, when the rotation angle range of the stirring tool 1 is the first angle range, the protruding structure 11 and the inner pot cover 21 are in a non-contact state.

[0048] The first angle range α refers to the angle range within which the stirring tool 1 performs rotational motion during the cooking process.

[0049] Furthermore, the working states of the stirring tool 1 can be divided into a stirring state and an open lid state. The stirring state refers to the working state of stirring the ingredients during the cooking process, and the open lid state refers to the working state of opening the inner pot lid 21. In the stirring state, the stirring tool 1 is in a non-contact state with the inner pot lid 21; in the open lid state, the stirring tool 1 will come into contact with the inner pot lid 21 when it moves to a certain position, and exert force on the inner pot lid 21, thereby pushing the inner pot lid 21 open.

[0050] Furthermore, in the stirring state, i.e., during the cooking process, the inner pot 2 and the inner pot cover 21 are in a high-pressure sealed state, and the stirring tool 1 stirs the ingredients in the inner pot 2. To avoid danger from collision between the stirring tool 1 and the inner pot cover 21, the range of motion of the stirring tool 1 is limited to a range that does not contact the inner pot cover 21. The first angle range can be flexibly adjusted according to the size of the protruding structure 11. For example, the first angle range α can be 160°. If the protruding structure 11 is large, the first angle range is reduced. If the protruding structure 11 is small, the first angle range can be appropriately expanded.

[0051] The embodiment of the present invention controls the stirring tool to rotate and stir within a first angle range during the cooking process, thereby stirring the ingredients to achieve the cooking function, preventing the ingredients from being overcooked, improving the cooking effect and practicality of the cooking device, enriching the functionality of the stirring tool, preventing collision with the inner pot cover under high pressure, and improving the safety of the cooking device.

[0052] See also Figure 8 、 Figure 9 、 Figure 10 and Figure 11 , Figure 8 、 Figure 9 There are two cross-sectional views, Figure 9 Therefore Figure 8 The BB shown in is a cross-sectional structure diagram generated by the cross section, such as Figure 9As shown, the stirring tool 1 rotates within the second angle range β, and can apply an outward thrust to the inner pot cover 21 at the two limit values ​​of the second angle range β, thereby pushing open the inner pot cover. As shown in the figure, in some possible embodiments, when cooking is completed, the stirring tool 1 performs a reciprocating motion within the second angle range β; the first angle range α is smaller than the second angle range β, and the preset position is the position of the stirring tool 1 at the limit value of the second angle range β.

[0053] The second angle range β is the angle range within which the stirring tool 1 rotates to perform the lid opening operation when the stirring tool 1 is in the lid opening state. Further, when cooking is completed, it is necessary to open the inner pot lid 21 from the inside so that the sealing member 22 on the inner pot lid 21 is separated from the inner wall of the inner pot 2. Since the stirring tool 1 does not come into contact with the inner pot lid 21 when rotating within the first angle range α, Figure 10 As shown, the sealing member 22 on the inner pot cover 21 is in contact with the inner wall of the inner pot 2. In order to open the inner pot cover 21, the stirring tool 1 needs to rotate within a larger angle range to come into contact with the inner pot cover 21 and exert a force on the inner pot cover 21 to separate it from the inner pot wall. Therefore, in this state, the stirring tool 1 is controlled to perform a reciprocating motion within the second angle range β.

[0054] Furthermore, the process of reciprocating motion within the second angular range β is as follows: when the stirring tool 1 rotates to a preset angular position on either side, the raised structure on the stirring tool 1 comes into contact with the inner pot cover 21 and begins to exert a force on the inner pot cover 21. When the stirring tool 1 rotates to the limit value of the second angular range β, the force of the raised structure pushes the inner pot cover 21 and the sealing member 22 away from the inner pot wall. Similarly, when the stirring tool 1 rotates to the other side, the sealing member 22 on the other side is pushed away from the inner pot wall. By exerting an outward pushing force on both sides of the inner pot cover 21, the inner pot cover 21 can be pushed open. Figure 11 As shown, the sealing member 22 is separated from the inner wall of the inner pot 2, making it convenient for the user to easily take out the inner pot cover 21 from the outside.

[0055] The embodiment of the present invention controls the stirring tool to rotate and open the lid within the second angle range β, and applies outward pushing forces to both sides of the inner pot lid, thereby improving the force uniformity of the inner pot lid, improving the efficiency of separating the inner pot lid and the inner pot, and enhancing the convenience of opening the inner pot lid. The function switching of the stirring tool is achieved through different angle ranges, and the stirring tool used to stir the ingredients is used to open the lid without adding other components to realize the lid opening function, thereby reducing the processing cost and difficulty of the cooking equipment and improving the practicality and utilization rate of the stirring tool.

[0056] In some possible embodiments, the stirring tool 1 is in an arc shape, and a fixing hole is provided at the end 12 of the stirring tool 1 , and the fixing hole is rotatably connected to the inner wall of the inner pot via a connecting structure.

[0057] like Figure 2 As shown, the stirring tool 1 is in the shape of a semicircular arc, wherein the two endpoints of the semicircular arc are the end portions 12 of the stirring tool 1, and the end portions 12 include a first end portion 121 and a second end portion 122. The stirring tool 1 is connected to the interior of the inner pot 2 through the fixing hole of the end portion 12 and the connecting structure. The present application does not make a restrictive description of the connecting structure. Exemplarily, the connecting structure may be a bolt or nut, etc., so that after the stirring tool 1 is connected to the inner wall of the inner pot, it can rotate in the inner pot 2 with the connecting structure as the rotation center, thereby achieving stirring of the ingredients or rotating to a preset position for opening the lid.

[0058] The embodiment of the present invention realizes cooking and lid opening functions within different angle ranges by arranging a rotatable stirring tool on the inner pot wall, thereby enriching the functionality of the cooking device, improving the convenience of opening the lid, and thus improving the practicality of the cooking device. The arc-shaped stirring tool is used to improve the fit with the inner wall of the inner pot, reduce damage to the inner wall of the inner pot, improve the uniformity of stirring of ingredients, and improve the cooking effect of the cooking device.

[0059] like Figure 4 、 Figure 5 As shown, in some possible embodiments, the bottom of the stirring tool 1 is in contact with the bottom of the inner pot 2, and the protruding structure 12 is provided on the bottom plane of the stirring tool 1;

[0060] The bottom plane is the plane where the bottom of the stirring tool 1 is located, and the bottom plane is perpendicular to the end plane of the stirring tool 1. The end plane is the plane where the end 12 of the stirring tool 1 contacts the inner wall of the inner pot.

[0061] Since the stirring tool 1 is semicircular, the bottom of the semicircular coincides with the bottom of the stirring tool 1 , and the shape of the stirring tool 1 fits the inner wall of the inner pot, so the bottom of the stirring tool 1 contacts the bottom of the inner pot 2 .

[0062] Furthermore, the protruding structure is used to apply an outward thrust to the inner pot cover 21 when the stirring tool 1 moves to the limit value of the second angle range β, thereby pushing open the inner pot cover 21.

[0063] As for the materials of the stirring tool 1 and the protruding structure, materials that meet food safety requirements, such as stainless steel or silicone, etc., may be used, and details thereof will not be repeated here.

[0064] The embodiment of the present invention provides a protruding structure at the bottom of the stirring tool. When the stirring tool rotates within the second angle range β, it can contact the inner pot cover and apply an outward pushing force to the inner pot cover at the position where the protruding structure contacts the inner pot cover, thereby separating the inner pot cover from the inner pot. This improves the force uniformity of the inner pot cover, improves the efficiency of separating the inner pot cover and the inner pot, saves manpower for opening the inner pot cover, improves the convenience of use of the cooking device, and improves the user experience. There is no need to set up additional components or use external tools to assist in opening the inner pot cover, thus saving manufacturing costs.

[0065] See also Figure 1 、 Figure 2 In some possible embodiments, the protruding structure 11 is obtained by extending the bottom of the stirring tool 1 toward both sides.

[0066] The present application does not limit the specific shape of the protrusion structure 11. The protrusion structure 11 can be of various shapes. For example, the protrusion structure 11 can be a sheet or block structure. Optionally, the sheet structure can be divided into a circular sheet structure, a sheet structure, etc., wherein the sheet protrusion includes a square protrusion, a diamond protrusion, etc. Figure 8 As shown, in some possible implementations, the protruding structure 11 is a square sheet structure, and the block structure can be divided into a square block structure, a spherical block structure, etc., which will not be repeated here.

[0067] The embodiment of the present invention extends protruding structures on both sides of the bottom of the stirring tool. When cooking is completed or in other non-cooking states, when the protruding structures rotate to a preset position, the inner cover is pushed outward to be opened, thereby overcoming the problem that the seal on the high-pressure inner cover and the inside of the pot body are tightly adhered and cannot be separated, thereby improving the convenience of using the cooking device and saving the manpower required to open the cover. By adding the protruding structure instead of relying on other auxiliary equipment, the component structure of the cooking device is simplified and the processing and manufacturing cost of the cooking device is reduced.

[0068] In some possible embodiments, the cooking device further includes an outer pot cover 31 , which is disposed on the outer pot and is used to press and lock the inner pot cover 21 .

[0069] The inner pot 2 is arranged in the outer pot 3. The outer pot fixes, keeps warm, and pressurizes the inner pot 2. A closed structure is formed between the outer pot cover 31 and the outer pot 3. The outer pot cover 31 presses the inner pot cover 21 tightly, thereby ensuring that a high-pressure sealing structure is formed between the inner pot 2 and the inner pot cover 21, ensuring the sealing of the high-pressure sealing structure.

[0070] In addition, when the inner pot 2 is in the cooking process, in addition to achieving the heat preservation effect by relying on the high-pressure sealed structure between the inner pot 2 and the inner pot cover 21, the outer pot cover 31 also presses the inner pot cover 21 to further lock in and preserve heat.

[0071] The embodiment of the present invention arranges the inner pot in the outer pot, arranges the outer pot cover on the outer pot, and presses the inner pot cover tightly, thereby enhancing the sealing of the high-pressure sealing structure between the inner pot and the inner pot cover, improving the high-pressure cooking effect of the cooking device, and optimizing the cooking performance of the cooking device.

[0072] See Figure 12 ,like Figure 12 As shown, the present invention also provides a control method for a cooking device having a high-pressure inner cover structure, wherein when cooking is completed, the method comprises:

[0073] S102: Sending a cover-opening signal to the stirring tool 1, so that the stirring tool 1 performs a reciprocating motion within a second angle range β in response to the cover-opening signal;

[0074] The stirring tool 1 is controlled by a driving device 8, which provides driving force for the rotational movement of the stirring tool 1, and controls the rotation angle range, rotation speed, and movement mode of the stirring tool 1 by controlling the driving device 8. For example, the movement mode includes the number of reciprocating motions, such as 1 reciprocating motion, multiple reciprocating motions, and multiple times means more than 2 times, such as 3 times, 4 times, 5 times, or continuous reciprocating motion within a preset time. Furthermore, the rotation speed of the stirring tool 1 can also be set according to the function of the stirring tool 1, which will not be repeated here.

[0075] Furthermore, the rotation angle range of the stirring tool 1 is determined by the function of the stirring tool 1. For example, when the lid opening function is realized, the rotation angle range is the second angle range β; when the stirring function is realized, the rotation angle range is the first angle range α. For the stirring function, different gears can be set to subdivide the first angle range α into multiple angle ranges.

[0076] S104: When the stirring tool 1 moves to a preset position, the raised structure on the stirring tool 1 pushes open the inner pot cover 21 and separates the inner pot cover 21 from the inner pot.

[0077] Among them, the preset position refers to the limit position of the second angle range β, and the limit position includes the positions of the two end points of the second angle range β. For example, when the second angle range β is 210°, the 0° line is the center line of the second angle range β, and the 0° line is a line perpendicular to the ground. The second angle range β refers to the angle range from 105° to the left of the 0° line to 105° to the right of the 0° line. Accordingly, the preset position refers to 105° to the left of the 0° line and 105° to the right of the 0° line.

[0078] The stirring tool 1 performs a reciprocating motion within the second angular range β, which means that the stirring tool 1 moves from any position to the position of one end point, and then moves to the position of the other end point. For example, taking the second angular range β as 210°, the stirring tool 1 first moves from any position where the stirring tool 1 is located to 105° to the left of the 0° line, and then moves to 105° to the right of the 0° line, or first moves from any position where the stirring tool 1 is located to 105° to the right of the 0° line, and then moves to 105° to the left of the 0° line. Thus, a reciprocating motion within the range of 210° is completed.

[0079] See Figure 7 and Figure 8 When the stirring tool 1 moves to any side limit position within the second angle range β, for example, when the stirring tool 1 moves to the position 105° to the left of the 0° line, the inner pot cover 21 and the inner wall of the inner pot change from a tightly fitted state to a separated state.

[0080] The embodiment of the present invention controls the stirring tool to perform a reciprocating motion within the second angle range β, so that the raised structure on the stirring tool exerts an outward thrust on the inner pot cover, thereby separating the sealing member on the inner pot cover from the inner wall of the inner pot, saving manpower for manually opening the inner pot cover and improving the convenience and practicality of the cooking device.

[0081] See also Figure 13 ,like Figure 13 As shown, in some possible embodiments, the cooking device further includes an outer pot cover 31, the outer pot cover 31 and the outer pot 3 form a closed structure, and the closed structure has a pressing effect on the inner pot cover 21. Before sending the cover-opening signal to the stirring tool 1, the method further includes:

[0082] S002: sending a pressure relief signal to the cooking device, so that the cooking device relieves pressure in response to the pressure relief signal;

[0083] After cooking in a high-pressure sealed state, the inner pot 2 of the cooking device needs to be depressurized. A pressure relief valve for pressure relief is provided on the inner pot cover 21. After cooking is completed, the inner pot 2 is filled with high-pressure steam. The system sends a pressure relief signal to the cooking device, causing the cooking device to relieve pressure in response to the pressure relief signal. The steam in the inner pot is discharged from the pot body to the outside of the pot body through the pressure relief valve, completing the pressure relief.

[0084] S004: After the pressure relief is completed, an unlocking signal is sent to the outer pot cover 31, so that the outer pot cover 31 responds to the unlocking signal, unlocks, and moves upward by a preset distance.

[0085] The outer pot lid 31, mounted on the outer pot, compresses the inner pot lid 21, further ensuring a strong high-pressure seal between the inner pot lid 21 and the inner pot 2. This prevents the inner pot lid 21 from being pushed away from the inner pot 2 by excessive pressure, potentially posing a danger to the user. Furthermore, it acts as an external safety device, locking the inner pot lid 21. After pressure relief is complete, the system sends an unlocking signal to the outer pot lid 31, unlocking it and moving it upward a preset distance, freeing it from compressing the inner pot lid 21 and facilitating its removal.

[0086] Furthermore, the preset distance can be set according to actual conditions. For example, the range of the preset distance can be 1-10 cm, such as 1 cm, 1.5 cm, 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm, 5 cm, 5.5 cm, 6 cm, 6.5 cm, 7 cm, 7.5 cm, 8 cm, etc.

[0087] The embodiment of the present invention provides an outer pot cover on the outer pot so that the outer pot cover presses the inner pot cover tightly, thereby improving the tightness of the connection between the inner pot cover and the inner pot, improving the stability of the high-pressure and high-temperature environment in the inner pot, improving the uniformity and sufficiency of heating food, optimizing the cooking effect of the cooking device, preventing the inner pot cover from rushing out and causing danger, improving the safety of the cooking device, and improving the practicality and reliability of the cooking device.

[0088] In some possible embodiments, during the cooking process, the method further includes:

[0089] A stirring signal is sent to the stirring tool 1 so that the stirring tool 1 performs reciprocating motion within a first angle range α in response to the stirring signal.

[0090] Optionally, the stirring tool 1 is controlled by a driving device 8, and the system sends a signal to the driving device 8. The driving device 8 controls the stirring tool 1 to rotate within a preset range according to preset angle range, rotation speed and other information. For example, when the signal is a stirring signal, the driving device 8 controls the stirring tool 1 to reciprocate within the first angle range α.

[0091] The embodiment of the present invention realizes the stirring function of the stirring tool by sending a stirring signal to the stirring tool, causing the stirring tool to reciprocate within a first angle range α, thereby improving the uniformity of heating the ingredients, improving the quality of the cooking device, and thus improving the practicality of the cooking device; at the same time, because the first angle range α is smaller than the second angle range β, the inner pot lid will not be touched during the stirring operation, reducing the possibility of accidentally opening the lid and improving cooking safety.

[0092] The implementation of the present invention has the following beneficial effects:

[0093] 1. In the embodiment of the present invention, a protruding structure is provided on the stirring tool. When cooking is completed, the stirring tool moves to a preset position and can push the inner pot lid open via the protruding structure, thereby preventing the seal from being tightly adhered to the wall of the inner pot and unable to be separated. This makes it easy to remove the inner pot lid from the inner pot, saves manpower in removing the inner pot lid, and improves the convenience and practicality of the cooking device. There is no need to reduce the elasticity of the seal, nor to rely on other complex components or external equipment to assist in opening the lid, which reduces the restrictions on the seal material and the difficulty of seal processing, reduces the dependence on auxiliary equipment, and thus saves processing and manufacturing costs.

[0094] 2. The embodiment of the present invention controls the stirring tool to rotate and stir within a first angle range during the cooking process, thereby stirring the ingredients to achieve the cooking function, preventing the ingredients from being overcooked, improving the cooking effect and practicality of the cooking device, enriching the functionality of the stirring tool, preventing collision with the inner pot cover under high pressure, and improving the safety of the cooking device.

[0095] 3. The embodiment of the present invention controls the stirring tool to rotate and open the lid within the second angle range, and applies outward pushing forces to both sides of the inner pot lid, thereby improving the force uniformity of the inner pot lid, improving the efficiency of separating the inner pot lid and the inner pot, and enhancing the convenience of opening the inner pot lid. The function switching of the stirring tool is achieved through different angle ranges, and the stirring tool used to stir the ingredients is used to open the lid without adding other components to realize the lid opening function, thereby reducing the processing cost and difficulty of the cooking equipment and improving the practicality and utilization rate of the stirring tool.

[0096] 4. The embodiment of the present invention realizes cooking and lid opening functions within different angle ranges by arranging a rotatable stirring tool on the inner pot wall, thereby enriching the functionality of the cooking device, improving the convenience of opening the lid, and thus improving the practicality of the cooking device. The arc-shaped stirring tool is used to improve the fit with the inner wall of the inner pot, reduce damage to the inner wall of the inner pot, improve the uniformity of stirring of ingredients, and improve the cooking effect of the cooking device.

[0097] 5. In the embodiment of the present invention, a raised structure is provided at the bottom of the stirring tool. When the stirring tool rotates within the second angular range, it can contact the inner pot cover and apply an outward pushing force to the inner pot cover at the position where the raised structure contacts the inner pot cover, thereby separating the inner pot cover from the inner pot. This improves the uniformity of force applied to the inner pot cover, improves the efficiency of separating the inner pot cover and the inner pot, saves manpower in opening the inner pot cover, improves the convenience of use of the cooking device, and enhances the user experience. No additional components or external tools are required to assist in opening the inner pot cover, thereby saving manufacturing costs.

[0098] 6. In the embodiment of the present invention, the inner pot is arranged in the outer pot, and the outer pot cover is arranged on the outer pot, and the inner pot cover is pressed tightly, thereby enhancing the sealing of the high-pressure sealing structure between the inner pot and the inner pot cover, improving the high-pressure cooking effect of the cooking device, and optimizing the cooking performance of the cooking device.

[0099] 7. In the embodiment of the present invention, protrusions extend from both sides of the bottom of the stirring tool. When cooking is complete or in other non-cooking states, the protrusions rotate to a preset position to push the inner lid outward to open. This overcomes the problem of the seal on the high-pressure inner lid being tightly adhered to the interior of the pot and unable to be separated, improves the convenience of use of the cooking device, and reduces the manpower required to open the lid. By adding the protrusions instead of relying on other auxiliary equipment, the component structure of the cooking device is simplified, reducing the processing and manufacturing costs of the cooking device.

[0100] 8. In the embodiment of the present invention, the stirring tool is controlled to perform a reciprocating motion within a second angular range, so that the raised structure on the stirring tool exerts an outward thrust on the inner pot cover, thereby separating the sealing member on the inner pot cover from the inner wall of the inner pot. This saves manpower in manually opening the inner pot cover and improves the convenience and practicality of the cooking device.

[0101] 9. The embodiment of the present invention provides an outer pot cover on the outer pot so that the outer pot cover presses the inner pot cover tightly, thereby improving the tightness of the connection between the inner pot cover and the inner pot, improving the stability of the high-pressure and high-temperature environment in the inner pot, improving the uniformity and sufficiency of heating food, optimizing the cooking effect of the cooking device, preventing the inner pot cover from rushing out and causing danger, improving the safety of the cooking device, and improving the practicality and reliability of the cooking device.

[0102] 10. The embodiment of the present invention realizes the stirring function of the stirring tool by sending a stirring signal to the stirring tool, causing the stirring tool to reciprocate within a first angular range, thereby improving the uniformity of heating the ingredients, improving the quality of the cooking device, and thus improving the practicality of the cooking device; at the same time, because the first angular range is smaller than the second angular range, the inner pot lid will not be touched during the stirring operation, reducing the possibility of accidentally opening the lid and improving cooking safety.
