Description

Technical Field

[0001] This invention relates to the field of high-pressure cooking technology, and in particular to a pot body assembly for a high-pressure cooking device, a cooking device, and a cooking method. Background Technology

[0002] Currently, there is a lack of household pressure cooking equipment on the market. Even pressure cookers have the following drawbacks: 1. The maximum pressure is less than 0.2MPa, and the corresponding cooking temperature is less than 120℃. At this temperature, the Maillard reaction has just begun, and the deliciousness of the food cannot be fully brought out; 2. Water needs to be added to the pot, so it is impossible to cook other methods besides boiling.

[0003] Cooking in a closed, high-pressure environment locks in the moisture of food, resulting in a smoother texture. Moreover, high-pressure cooking can significantly reduce cooking time, thus providing effects that cannot be matched by cooking under normal or low pressure.

[0004] Ideal high-pressure cooking equipment has the following characteristics: 1. Safety; 2. Pressure can reach above 0.3MPa, which can induce the Maillard reaction in food from the outside to the inside, while the food surface will not become abnormally dry due to lack of water; 3. Uniform heating; 4. Can cook most common foods without adding water; 5. Significantly shortens the cooking time of existing cooking equipment. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, a pot body component, cooking device and cooking method for high-pressure cooking equipment are provided, which can realize the creation of a high-pressure environment in the pressure cooker to cook food, effectively lock in the moisture of the food and greatly reduce the cooking time, realize waterless high-pressure frying and baking of most foods, and make the cooked food more tender in taste by high-pressure air heating, thereby overcoming at least one of the above-mentioned technical defects.

[0006] The specific technical solution is as follows:

[0007] A pot body assembly for a high-pressure cooking device, comprising:

[0008] The pressure cooker body has an internal cavity for holding food. The pressure cooker body has at least one connecting structure, and each connecting structure has a pressure relief hole that connects to the cavity.

[0009] The connecting components, in equal and compatible numbers with the connecting structures, are used to detachably mount the pressure cooker body into the cooking chamber of the high-pressure cooking equipment. The connecting components have internal gas channels that connect the pressure relief hole to the outside of the connecting components. Each gas channel is provided with a movable valve block and an elastic component that causes the valve block to move toward the pressure relief hole. The valve block has a first position state that causes the pressure relief hole to block the gas channel and a second position state that causes the pressure relief hole to be connected to the gas channel.

[0010] Furthermore, when the air pressure inside the containment cavity is higher than the preset value, the high air pressure inside the containment cavity can push the valve block from the first position state to the second position state to release pressure, and when the air pressure inside the containment cavity is not higher than the preset value, the elastic member can push the valve block from the second position state to the first position state to maintain the high pressure state inside the containment cavity.

[0011] Preferably, the connecting structure is an inwardly recessed mounting groove formed on the pressure cooker body, a pressure relief through hole is opened on the inner bottom surface of the mounting groove, and one end of the connecting member is detachably assembled in the mounting groove and can be moved along the depth direction of the mounting groove for assembly or disassembly.

[0012] During the process of the connecting component being dislodged from the mounting groove, the valve block changes from the first position state to the second position state, causing the receiving cavity to be depressurized by connecting the gas flow channel through the pressure relief through hole.

[0013] Preferably, the end of the connecting member away from the pressure cooker body also forms a connecting shaft structure for shaft connection to the cooking device, and the cooking device has a built-in motor, the motor shaft of the motor is connected to at least one of the connecting shaft structures to drive the connecting member and the pressure cooker body to rotate in the cooking cavity.

[0014] Preferably, the pressure cooker body includes a pot body and a lid. The pot body has an opening for inserting food and is closed by the lid. The inner wall of the lid has internal threads, and the outer periphery of the pot body has external threads that are adapted to the internal threads and are incomplete, so as to release the residual pressure in the cavity during the spiral opening of the lid.

[0015] Preferably, there are two connecting components, and the bottom of the pot body and the lid each form a mounting groove. The two mounting grooves are arranged coaxially, and the ends of the two connecting components away from the pot body are respectively shaft-connected to the cooking equipment, so as to rotatably assemble the pot body in a horizontal position in the cooking cavity, and the motor in the cooking equipment drives the connecting components and the pressure pot body to rotate.

[0016] Preferably, each of the two connecting members is detachably fitted with a bracket, the bracket having a downward-opening cavity, and the bracket having a through-hole on both sides, allowing one end of the connecting member to pass through the through-hole and be axially connected to the cooking device, and allowing the connecting member to rotate relative to the bracket.

[0017] The gas flow channel is formed on the outer peripheral wall of the connecting member at one end away from the main body of the pot and is connected to the cavity. This allows the high-pressure gas in the cavity to flow into the cavity through the pressure relief hole and the gas flow channel and flow out from the lower open end of the cavity.

[0018] Preferably, the connecting components include a valve core, a valve cover, a valve block, and an elastic member. The valve core has a gas flow channel. The side of the gas flow channel adjacent to the main body of the pot serves as a valve cavity, which sequentially houses the elastic member and the valve block that can move back and forth within the valve cavity. The valve cover covers the front end of the valve cavity and prevents the valve block from moving forward out of the valve cavity. The valve cover has an opening, and the front end of the valve block is also fitted with a sealing block for blocking the pressure relief hole. The sealing block can extend forward out of the opening under the action of the elastic member.

[0019] The present invention also relates to a cooking device, including a main body of the device, a fryer body that can be assembled in a drawer-like manner from one side of the main body of the device, and a pressure cooking device pot assembly as described above, wherein the pot assembly is detachably disposed in the fryer body.

[0020] The present invention also relates to a cooking method of a cooking device, the cooking device including a main body, a fryer body that can be assembled into the main body in a drawer-like manner, and a pot body assembly that is detachably disposed in the fryer body. The pot body assembly includes a pressure cooker body, two connecting members disposed on opposite sides of the pressure cooker body, and two supports, and each support is respectively assembled on a connecting member.

[0021] Cooking methods include the pre-cooking process, the high-pressure cooking process, and the post-cooking removal process; among them,

[0022] The pre-cooking process for food includes:

[0023] Step a: Place the food into the pressure cooker and partially insert the two sets of assembled brackets and connecting components into the two mounting slots located opposite each other at both ends of the pressure cooker.

[0024] Step b, the valve block in the connecting component seals the pressure relief through hole in the mounting groove, and further squeezes the two supports in opposite directions so that the overall lateral length of the pressure cooker body and the two connecting components is less than the lateral length of the internal accommodating space of the fryer body, so as to place the pressure cooker body into the fryer body.

[0025] Step c: Align the connecting shaft structure at one end of the two connecting components opposite to the assembly hole on the inner side wall of the fryer, and loosen the two supports so that the two connecting components move in opposite directions under the action of the spring inside the connecting components, thereby assembling the connecting shaft structure into the two corresponding assembly holes, and the valve block is still in the state of blocking the pressure relief hole under the action of the spring.

[0026] Step d: Assemble the fryer body into the main body of the equipment in a drawer-type structure, and connect the motor built into the main body of the equipment to one of the connecting shaft structures.

[0027] The process of removing food after cooking includes:

[0028] Step 1: Remove the fryer body from the main body of the equipment using a drawer-type structure, and remove the two supports and connecting components from the mounting slot in opposite directions. During this process, the valve block no longer blocks the pressure relief hole, allowing the high-pressure airflow inside the pressure cooker to pass through the pressure relief hole, the gas flow channel in the valve block, and the cavity in the support in sequence, and then spray downward from the lower open end of the support.

[0029] Step two: Completely remove the two brackets from the mounting slots, and unscrew the lid of the pressure cooker from the main body of the pressure cooker to expose the cavity containing the food. During this process, the incomplete external threads on the outer periphery of the main body of the pressure cooker cause the residual pressure inside the pressure cooker to be released through the thread gaps.

[0030] Preferably, during the high-pressure cooking process, when the pressure inside the pot body is higher than the preset value, the high pressure inside the pot body can be released by opening the valve block through the pressure relief hole. When the pressure inside the pot body is not higher than the preset value, the spring can push the valve block to the position of blocking the pressure relief hole to maintain the high pressure state inside the pot body.

[0031] The beneficial effects of the above technical solution are as follows:

[0032] (1) The pressure cooker body assembly for high-pressure cooking equipment includes a pressure cooker body, a connecting structure, and connecting components. The connecting structure has a pressure relief hole, and the connecting components have a gas flow channel and are equipped with a valve block and elastic components. This enables the detachable pressure cooker body with self-pressure relief function to be installed in the cooking equipment, so as to create a high-pressure environment in the pressure cooker body to cook food, effectively lock in the moisture of the food and greatly reduce the cooking time, and realize waterless high-pressure frying and roasting of most foods. High-pressure air heating can make the cooked food taste better and more tender.

[0033] (2) This cooking device can be easily assembled and removed from the pot body components. During the cooking process, it automatically releases pressure based on the high pressure inside the pot body. When removing food, the high-pressure gas is first sprayed out in a downward direction to improve safety. Then, the residual pressure is released through the incomplete external thread structure, which makes the incomplete external thread form a pressure relief channel. If a large amount of gas rushes out when the user unscrews the lid, the user will naturally stop opening it, which can play a key warning role. Attached Figure Description

[0044] To make the technical means, creative features, achieved objectives, and effects of this invention easily understood, the following embodiments, in conjunction with the accompanying drawings, provide a detailed description of the invention. And define... Figure 6 The up, down, left, and right directions shown on the paper are the up, down, left, and right directions in this scheme, and are defined as follows: Figure 3 The direction from left to right shown on the paper is the same as the direction from back to front for the valve core in this design.

[0045] Example 1,

[0046] See Figures 1 to 6 As shown in the illustration, this embodiment provides a pot body assembly for a high-pressure cooking device, comprising:

[0047] The pressure cooker body 20 has an internal cavity 200 for holding food. The pressure cooker body 20 has at least one connecting structure, and each connecting structure has a pressure relief hole 202 that communicates with the cavity 200.

[0048] The connecting member 1, which is the same number and compatible with the connecting structure, is used to detachably place the pressure cooker body 20 into the cooking cavity of the high-pressure cooking equipment. The connecting member 1 has a gas channel 4 that connects the pressure relief hole 202 to the outside of the connecting member. Each gas channel 4 is provided with a movable valve block 102 and an elastic member 103 that causes the valve block 102 to move toward the pressure relief hole 202. The valve block 102 has a first position state that causes the pressure relief hole 202 to block the gas channel 4 and a second position state that causes the pressure relief hole 202 to be connected to the gas channel 4.

[0049] Furthermore, when the air pressure inside the accommodating cavity 200 is higher than the preset value, the high air pressure inside the accommodating cavity 200 can push the valve block 102 from the first position state to the second position state to release pressure, and when the air pressure inside the accommodating cavity 200 is not higher than the preset value, the elastic member 103 can push the valve block 102 from the second position state to the first position state to maintain the high pressure state inside the accommodating cavity 200.

[0050] Based on the above technical solution, the pressure cooker body 20 component for high-pressure cooking equipment includes a pressure cooker body 20, a connecting structure, and a connecting member 1. The connecting structure has a pressure relief hole 202, and the connecting member 1 has a gas flow channel 4 and is equipped with a valve block 102 and an elastic member 103. This enables the detachable installation of a pressure cooker body 20 with a self-releasing function within the cooking equipment, thereby creating a high-pressure environment within the pressure cooker body 20 to cook food. This effectively locks in the moisture of the food and significantly reduces cooking time, while also enabling waterless high-pressure frying and grilling of most foods. High-pressure air heating makes the cooked food taste more tender.

[0051] In a preferred embodiment, the connecting structure is a mounting groove 201 recessed inward on the pressure cooker body 20, and a pressure relief hole 202 is formed on the inner bottom surface of the mounting groove 201. One end of the connecting member 1 is detachably fitted into the mounting groove 201 and can move along the depth direction of the mounting groove 201 for assembly or disassembly. During the process of the connecting member 1 being disassembled outward from the mounting groove 201, the valve block 102 changes from a first position state to a second position state, causing the receiving cavity 200 to be connected to the gas flow channel 4 through the pressure relief hole 202 for pressure relief. That is, during the process of removing the connecting member 1, a preliminary pressure relief process is performed on the high-pressure environment inside the pressure cooker body 20. Furthermore, based on the above, the connecting member 1 can obviously also be configured as a non-detachable structure from the pressure cooker body 20, which can satisfy the pressure relief through the movement of the valve block 102 to achieve the above technical purpose. Correspondingly, the connecting structure does not need to be designed as a groove structure. For example, it can be designed as a flat or convex structure with a pressure relief through hole 202, and the connecting member 1 can be fixed in the corresponding position to satisfy the pressure relief function between them. It is not limited to this.

[0052] As a further preferred embodiment, combined with Figures 3 to 5 As shown, the end of the connecting member 1 facing away from the pressure cooker body 20 also forms a connecting shaft structure 100 for shaft connection within the cooking device. The cooking device contains a built-in motor 7, and the motor shaft 701 of the motor 7 is driven by at least one of the connecting shaft structures 100 to drive the connecting member 1 and the pressure cooker body 20 to rotate within the cooking cavity, thereby ensuring more even heating of the food within the pressure cooker body 20. Specifically, the head end of the connecting shaft structure 100 has a connecting groove, within which a spline structure 1012 is formed for shaft connection with the motor shaft 701. A guide groove 1011 is also formed on the outward side of this connecting groove, allowing the connecting shaft structure 100 to rotate opposite the motor shaft 701 of the geared motor.

[0053] In a preferred embodiment, specifically as follows: Figure 1 and Figure 2 As shown, the pressure cooker body 20 includes a main body 2 and a lid 3. The main body 2 has an opening for placing food, which is closed by the lid 3. The inner wall of the lid 3 has internal threads, and the outer periphery of the main body 2 has a partially threaded external thread 204 that matches the internal threads. This allows residual pressure in the receiving cavity 200 to be released during the unscrewing of the lid 3. This further improves safety. Even if high pressure still exists inside the pressure cooker body 20, the partially threaded external thread 204 forms a pressure relief channel when the lid 3 is unscrewed. If a large amount of gas rushes out when the user unscrews the lid 3, they will naturally stop opening it, serving a crucial warning function.

[0054] As a further preferred embodiment, in this embodiment, there are two connecting members 1, and a mounting groove 201 is formed on the bottom of the pot body 2 and the lid 3 respectively. The two mounting grooves 201 are arranged coaxially, and the ends of the two connecting members 1 away from the pot body 2 are respectively axially connected to the cooking device, so as to rotatably assemble the pot body 2 in a horizontal position in the cooking cavity, and the motor 7 in the cooking device drives the connecting members 1 and the pressure pot body 20 to rotate.

[0055] As a further preferred embodiment, brackets 106 are detachably assembled on the two connecting members 1 respectively. A cavity 1062 with a downward opening is formed in the bracket 106, and channels 1061 are formed through both sides of the bracket 106 to allow one end of the connecting member 1 to pass through the channel 1061 and be axially connected to the cooking device, and allow the connecting member 1 to rotate relative to the bracket 106; the end of the gas flow channel 4 away from the pot body 2 is formed on the outer peripheral wall of the connecting member 1 and communicates with the cavity 1062 to allow the high-pressure gas in the accommodation cavity 200 to flow into the cavity 1062 through the pressure relief through hole 202 and the gas flow channel 4 and flow out from the downward opening end of the cavity 1062. That is, the gas is exhausted downward during the pressure relief process, which can avoid the risk of scalding the user by high-temperature and high-pressure gas or steam. Further, a longitudinally telescopic pull rod 107 is also installed on the bracket 106. A longitudinally penetrating mounting through hole 1063 is formed in the bracket 106. The lower end of the pull rod 107 extends downward into the mounting through hole 1063 and is detachably provided with a limiting block 108 to allow the pull rod 107 to longitudinally expand and contract along the mounting through hole 1063 and limit the pull rod 107 from protruding upward out of the mounting through hole 1063. In addition, in this embodiment, the pull rod 107 is integrally in an inverted U shape, but is not limited thereto.

[0056] As a further preferred embodiment, in combination Figures 3 to 5 as shown in, the connecting member 1 includes a valve core 101, a valve cover 105, a valve block 102, and an elastic member 103. A gas flow channel 4 is formed in the valve core 101. The side of the gas flow channel 4 adjacent to the pot body 2 is used as a valve cavity 1014 and sequentially accommodates an elastic member 103 and a valve block 102 capable of moving back and forth in the valve cavity 1014. The valve cover 105 covers the front end of the valve cavity 1014 and limits the valve block 102 from protruding forward out of the valve cavity 1014. The valve cover 105 has an opening, and a plugging block 104 for blocking the pressure relief through hole 202 is also connected to the front end of the valve block 102 and can protrude forward out of the opening under the action of the elastic member 103. Further, an annular stepped surface is formed on the outer circumference of the rear part of the valve core 101, and the front end surface of the bracket 106 abuts against the annular stepped surface. On the one hand, it is used as a positioning stepped surface, and on the other hand, it allows the two valve cores 101 to be further retracted into the installation groove 201 by squeezing the two brackets 106 in the opposite direction, so as to shorten the transverse length of the two valve cores 101 + the high-pressure pot body 20, facilitating placement into the cooking cavity. After relaxing the two brackets 106, due to the action of the elastic member 103, the transverse length of the two valve cores 101 + the high-pressure pot body 20 becomes longer, so that the rear ends of the two valve cores 101 (as the above-mentioned connecting shaft structure 100) are assembled into the cooking device to achieve the purpose of allowing the high-pressure pot body 20 and the connecting member 1 to rotate axially. Further, in combination Figure 5As shown, the valve block 102 comprises a columnar central block and spoke-shaped support blocks extending radially outward from the outer periphery of the central block, ensuring a flow channel between the valve block 102 and the valve cavity 1014, thus preventing blockage of the valve cavity 1014 and the gas flow channel 4 due to the movement of the valve block 102. Simultaneously, designing the valve block 102 to have a clearance fit with the inner wall of the valve cavity 1014 also achieves gas flow. Furthermore, the elastic member 103 is a spring, with its two ends abutting against the inner bottom surface of the valve cavity 1014 and the outer edge of the support block, respectively, to provide elastic force. Alternatively, the elastic member 103 can be other elastic blocks, such as elastic rubber, abutting against the rear end face of the valve block 102 to achieve the same technical objective. Furthermore, the bracket 106 and the valve core 101 are also connected by a pin 109 to limit their movement, so that they remain in a detachable assembly state that allows the valve core 101 to rotate relative to it. Specifically, a hole is made in the rear of the valve core 101 and the pin 109 is inserted therein. The protruding part of the pin 109 extends into the cavity 1062 of the bracket 106 to limit the axial movement of the bracket 106 along the valve core 101 while allowing the valve core 101 to rotate relative to the bracket 106. Furthermore, in the pressure cooker body 20, a sealing gasket is also provided between the upper open end of the pot body 2 and the lid 3.

[0057] It is worth noting that the preset air pressure value inside the accommodating cavity 200 used in this embodiment is no higher than 3MPa. That is, when this value is exceeded, the valve block 102 is pushed open to release pressure. However, this value can be adjusted based on specific requirements and the internal capacity of the pressure cooker body 20 and the selection of the elastic member 103. In this embodiment, the pressure cooker body 20 is horizontally placed and rotatable. However, it is also possible to design it to be vertically placed and rotatable and detachable within the cooking cavity by a connecting member 1 at the bottom. That is, the pressure cooker body 20, as a rotatable inner pot structure of the cooking device, can also achieve the above-mentioned technical objectives, and is therefore not limited to this. The aforementioned incomplete external thread 204 refers to the fact that the external thread 204 is partially cut off. Meanwhile, when considering the pressure cooker body as merely a high-pressure inner pot structure for cooking, without considering whether it can rotate or ignoring whether its designed shape is horizontal, vertical, or inclined, the number of connecting structures and connecting components can be greater to maintain its stability, such as three, four, five, or more designs. It is only necessary to ensure that it can be detached and removed to meet the purposes of cleaning and easy food removal. Obviously, this is also within the scope of consideration and protection of this design. In this application, the pressure cooker body mainly adopts a cylindrical structure, but based on the above, it can also adopt a square, rhomboid, or other irregular structure, and is not limited to this.

[0058] Example 2,

[0059] Combination Figure 7 and Figure 8As shown, the present invention also provides a cooking device, including a device body 6, a fryer pot body 5 that can be assembled into the device body 6 in a drawer-like manner from one side of the device body 6, and a pot body assembly for a high-pressure cooking device as described in Embodiment 1 above, wherein the pot body assembly is detachably disposed in the fryer pot body 5.

[0060] In a preferred embodiment, a motor 7 is fixedly mounted inside the main body 6 of the device. The motor shaft 701 of the motor 7 passes through the side wall of the fryer body 5 and is drively connected to one of the connecting members 1 of the fryer body assembly. Furthermore, the fryer body 5 has a cooking chamber inside, and a heating element 8 and a fan 9 are arranged sequentially from bottom to top above the cooking chamber. The fryer body assembly is horizontally positioned in the cooking chamber and can rotate, resulting in more even heating and maintaining high pressure inside the fryer body, thus improving the taste of the food. In this embodiment, the cooking device is an air fryer, but it is not limited to this.

[0061] Example 3,

[0062] Combination Figures 9a-9e ,as well as Figure 10a and Figure 10b As shown, the present invention also provides a cooking method for a cooking device. The cooking device includes a main body 6, a fryer pot body 5 that can be assembled into the main body 6 in a drawer-like manner from one side of the main body 6, and a pot body assembly detachably disposed within the fryer pot body 5. The pot body assembly includes a pressure cooker body 20, two connecting members 1 disposed on opposite sides of the pressure cooker body 20, and two supports 106, with each support 106 detachably mounted on one connecting member 1. The cooking method includes a pre-cooking process, a high-pressure cooking process, and a post-cooking removal process, wherein...

[0063] The pre-cooking process for food includes:

[0064] Step a: Place the food into the pressure cooker body 20, and partially insert the two sets of assembled brackets 106 and connecting components 1 into the two mounting slots 201 that are set opposite to each other at both ends of the pressure cooker body 20.

[0065] Step b, the valve block 102 in the connecting member 1 blocks the pressure relief through hole 202 opened in the mounting groove 201, and further squeezes the two supports 106 in opposite directions so that the overall lateral length of the pressure cooker body 20 and the two connecting members 1 is less than the lateral length of the internal accommodating space of the fryer body 5, so as to place the pressure cooker body 20 into the fryer body 5.

[0066] Step c, align the connecting shaft structure 100 at one end of the two connecting members 1 with the assembly hole on the inner wall of the fryer body 5, and loosen the two supports 106 so that the two connecting members 1 move in opposite directions under the action of the spring inside the connecting member 1, thereby assembling the connecting shaft structure 100 into the two corresponding assembly holes, and the valve block 102 is still in the state of blocking the pressure relief through hole 202 under the action of the spring.

[0067] Step d: The fryer body 5 is assembled into the main body 6 of the equipment in a drawer-type structure. The motor 7 built into the main body 6 is connected to the connecting shaft structure 100 of one of the connecting components 1.

[0068] The process of removing food after cooking includes:

[0069] Step 1: Remove the fryer body 5 from the cooking equipment using a drawer-type structure, and remove the two supports 106 from the mounting slot 201 with the connecting component 1 in opposite directions. During this process, the valve block 102 no longer blocks the pressure relief hole 202, allowing the high-pressure airflow inside the pressure cooker body 20 to pass through the pressure relief hole 202, the gas flow channel 4 in the valve block 102, and the cavity 1062 in the support 106 in sequence, and then spray downward from the lower open end of the support 106, which is safer.

[0070] Step 2: Completely remove the two brackets 106 from the mounting slot 201, and unscrew the lid 3 of the pressure cooker body 20 from the main body 2 of the pressure cooker body 20 to expose the container cavity 200 containing food. During this process, the incomplete external threads 204 on the outer periphery of the main body 2 of the pot body cause the residual pressure inside the pressure cooker body 20 to be released through the thread gap.

[0071] In a preferred embodiment, during the high-pressure cooking process, when the air pressure inside the pot body 2 is higher than a preset value, the high air pressure inside the pot body 2 can be released by opening the valve block 102 through the pressure relief hole 202. When the air pressure inside the pot body 2 is not higher than the preset value, the spring can push the valve block 102 to the position of blocking the pressure relief hole 202 to maintain the high pressure state inside the pot body 2.

[0072] Based on the above technical solution, this cooking device can easily assemble and remove the pot body components. During the cooking process, it automatically releases pressure based on the high pressure inside the main body 2 of the pot. When removing food, the high-pressure gas is first ejected downwards to improve safety. Then, the residual pressure is released through the incomplete external thread 204 structure, so that the incomplete external thread 204 constitutes a pressure relief channel 1061. If a large amount of gas rushes out when the user unscrews the lid 3, the user will naturally stop opening it, which can play a key warning role.

[0073] Furthermore, the aforementioned motor 7 is a geared motor used to enable the pressure cooker body 20 to rotate. The pressure cooker body 20 is first inserted into the mounting holes on the fryer body 5 through the connecting shaft structures 100 at both ends. Then, the entire fryer body 5 drawer is pushed into the main body 6 of the equipment. The guide groove 1011 on the connecting shaft structure 100 allows the connecting shaft structure 100 to rotate opposite to the motor shaft 701 of the geared motor. Since the motor shaft 701 is not circular, there will be situations where the motor shaft 701 can be inserted into the spline and situations where it cannot be inserted into the spline. When it cannot be inserted, the motor shaft 701 squeezes the valve core 101 to move backward (the valve core 101 has a built-in spring and a certain amount of forward and backward movement space). In this way, even if it cannot be inserted, it will not affect the fryer body 5 from being pushed into place. When the motor shaft 701 rotates, the motor shaft 701 can easily enter the spline. Therefore, there is no technical risk in the connection between the pressure cooker body 20 and the motor 7. Users can pour food (vegetarian or meat) into the main body 2 of the pot without adding water, or add a small amount of water, screw on the lid 3 and follow the above steps to achieve high-pressure frying and grilling, which is convenient and safe.

[0074] It is worth noting that when cooking food under high temperature and pressure, non-puffed food rotates automatically within the pressure cooker body 20, and the internal moisture remains liquid under high pressure. This prevents the food surface from charring prematurely, but it will still char slowly. This is because a safe high pressure (3MPa preset in this design) is set (through spring parameterization). The cooking device, with the help of the heating element 8 and fan 9, can easily create a 200℃ hot air circulation system. This system directly heats the pressure cooker body 20, and the 200℃ high temperature quickly raises the temperature inside the pressure cooker body 20 to over 100℃. As the pressure rises continuously, the pressure inside the pressure cooker body 20 also increases. Once the set value is reached, the valve block 102 and the sealing block 104 are pushed open, allowing some steam to escape. After the pressure decreases, the sealing block 104 re-seals the pressure relief hole 202. This cycle greatly prolongs the charring time of the food surface, allowing the food to absorb heat more quickly. This patent utilizes air heating of the pressure cooker body 20, resulting in gentler heat transfer and far better food heating uniformity than the localized, intense heating of a stovetop.

[0075] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
