Description

Technical Field

[0001] This application relates to the field of cooking appliance technology, specifically to a steam cooking appliance. Background Technology

[0002] Currently, there are many types of steam cooking appliances, such as steam rice cookers, steam stew pots, and steam hot pots, with various shapes and sizes. They mainly cook food by heating water into steam and then introducing it into the cooking chamber. Taking cooking rice in a steam rice cooker as an example, after the high-temperature steam is introduced into the cooking chamber, the steam can be fully mixed with the rice, causing the rice to tumble vigorously, absorb water, and be heated. Moreover, steam heating causes little damage to the molecular structure of rice, which can preserve the original flavor of the rice to a large extent and bring out the natural fresh taste of the rice. Therefore, steam rice cookers are loved by a wide range of consumers.

[0003] However, feedback from many users of steam cooking appliances reveals that most steam cooking appliances on the market still have many common defects. For example, during cooking, the rising steam can easily cause the lid to float up and down, which not only causes steam leakage and reduces cooking efficiency, but may also cause safety issues due to the leakage of high-temperature steam and the splashing of hot soup. For cooking appliances with steam guides and steam pipes on the lid, the floating of the lid will also affect the stable delivery of steam.

[0004] Meanwhile, an existing steam cooking appliance generates steam through a steam generating unit in the pot, which is then transported to the lid via internal pipes. From there, the steam is transported to the cooking chamber via a steam pipe assembly on the lid. Since the lid is removable and can be placed on the pot, users can remove it from the pot at any time. During cooking, the steam generating unit does not change its operating state regardless of whether the lid is on the pot. If the lid is opened midway, a large amount of high-temperature steam will be ejected upwards from the steam outlet on the pot, which could easily burn the user and pose a safety hazard. Summary of the Invention

[0005] This application provides a steam cooking appliance to solve at least one of the above-mentioned technical problems.

[0006] The technical solution adopted in this application is as follows:

[0007] A steam cooking appliance includes a pot body and a lid removably placed on the pot body. The cooking appliance also includes a swing arm hinged to the pot body, which has a first state in which the lid is pressed against the pot body when it is closed, and a second state in which it rotates toward one side of the pot body to allow the lid to be removed from the pot body. The pot body is provided with a steam generating unit, and the lid is provided with a steam pipe assembly that can communicate with the steam generating unit. In both the first and second states, the steam generating unit can provide steam to the cooking chamber of the steam cooking appliance through the lid.

[0008] The steam cooking appliance in this application also has the following additional technical features:

[0009] The swing arm includes a horizontal part and a connecting part. The connecting part is hinged to the pot body. The horizontal part is used to press the pot lid tightly, and the horizontal part is provided with an operation display panel.

[0010] In the first state, there is a gap between the horizontal section and the steam pipe assembly to form an air layer between the horizontal section and the steam pipe assembly.

[0011] The steam pipe assembly protrudes from the pot lid, and the swing arm includes a main body extending horizontally and a flange portion disposed around the periphery of the main body and extending downward to wrap around the side of the steam pipe assembly.

[0012] The outer side of the flipping part is provided with a handle, and in the first state, there is an avoidance gap between the handle and the pot lid.

[0013] A buffer is provided on the side of the main body facing the pot lid and / or on the side of the steam pipe assembly facing the main body.

[0014] The cooking appliance further includes a limiting seat, which is movably disposed on the pot body to have a locked position and an unlocked position; in the locked position, the limiting seat cooperates with the swing arm stop to limit the swing arm in the second state; in the unlocked position, the limiting seat releases the limitation on the swing arm, and the swing arm can switch from the second state to the first state; the pot lid has a trigger part, and the limiting seat has a mating part; when the pot lid closes the pot body, the trigger part drives the mating part to move, and the limiting seat switches from the locked position to the unlocked position.

[0015] In the second state, the angle between the swing arm and the radial direction of the pot body can be greater than or equal to 90°, so that the pot lid can be removed from the pot body in the up-down direction.

[0016] The limiting seat moves up and down relative to the pot body to switch between the locked position and the unlocked position; or, the trigger part is provided with a driving inclined surface, the mating part is provided with a driven inclined surface, and the limiting seat moves laterally relative to the pot body to switch between the locked position and the unlocked position.

[0017] The pot body is provided with a viewing window, and the cooking utensil also includes a transparent inner pot that can be inserted into the pot body.

[0018] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows:

[0019] 1. In the steam cooking appliance provided in this application, the pressure exerted by the swing arm on the lid during cooking limits the lid and counteracts the lifting force exerted on the lid by rising steam, preventing the lid from floating. This prevents steam from escaping through the gap between the lid and the pot body and prevents hot liquid from splashing out through this gap. Furthermore, because the lid has a pressing swing arm, if the user accidentally tries to open the lid during cooking, the swing arm will block it. Only by switching the swing arm from the first state to the second state can the lid be removed or placed, providing added safety. Finally, since the steam generating unit can supply steam to the cooking chamber of the steam cooking appliance through the lid in both the first and second states, even if the user accidentally switches the swing arm to the second state, there is no possibility of a large amount of hot steam escaping, eliminating the risk of burns.

[0020] 2. As a preferred embodiment of this application, the swing arm includes a horizontal part and a connecting part. The connecting part is hinged to the pot body, the horizontal part is used to press the pot lid, and the horizontal part is provided with an operation display panel. This allows the swing arm to not only press the pot lid to limit its position, but also to realize the upward placement of the operation display panel. Compared with the traditional steam cooking appliance where the display panel is set on the side of the pot body, it is more convenient for users to observe and operate the operation display panel, and saves the design space on the side of the pot body to leave more room for optimization design such as visualization, decoration, and atmosphere.

[0021] 3. In a preferred embodiment of this application, in the first state, an air layer is formed between the horizontal part and the steam pipe assembly by having a gap. The presence of the air layer can improve the heat preservation effect and achieve heat insulation, preventing the high temperature of the steam pipe assembly from being directly transferred to the swing arm through direct contact, thereby reducing the temperature rise of the swing arm during cooking. On the one hand, this ensures the normal operation of the operation display panel, and on the other hand, if the temperature rise of the swing arm is low, it also makes it easier for the user to open the lid.

[0022] 4. As a preferred embodiment of this application, by having the steam pipe assembly protrude from the pot lid, the swing arm includes a main body extending in a horizontal direction and a flange portion disposed around the periphery of the main body and extending downward, so that the swing arm can not only wrap around the top of the steam pipe assembly through the main body, but also wrap around the side of the steam pipe assembly through the flange portion. The swing arm has a larger wrapping area on the steam pipe assembly, thereby improving the heat preservation effect of the steam flowing through the steam pipe assembly, and further improving the steam heating efficiency and cooking efficiency.

[0023] As a preferred embodiment of this implementation, a handle is provided on the outer side of the flange. In the first state, there is a clearance between the handle and the lid, which makes it convenient for the user to put their hand into the clearance to rotate the arm by operating the handle.

[0024] As a preferred embodiment of this implementation, by providing a buffer on the side of the main body facing the pot lid and / or the side of the steam pipe assembly facing the main body, on the one hand, it avoids the rebound of the swing arm after it falls without buffering, reduces the vibration of the swing arm, and improves the installation reliability and service life of the electronic components inside the swing arm corresponding to the operation display panel. On the other hand, it can also prevent the swing arm from directly colliding with the pot lid, which would cause scratches between them and reduce the aesthetics.

[0025] 5. As a preferred embodiment of this application, the limiting seat movably disposed on the pot body has a locked position that restricts the swing arm to a second state and an unlocked position that releases the restriction on the swing arm. When the pot lid is closed, the limiting seat switches from the locked position to the unlocked position. In other words, when the pot lid is closed, the limiting seat releases the restriction on the swing arm, and the swing arm can automatically rotate from the second state to the first state that presses against the pot lid. Therefore, during the entire lid-closing process, only the pot lid needs to be closed to achieve automatic closing of the swing arm, saving the user's operation steps and also preventing the user from forgetting to close the swing arm, which would affect the normal display and use of the display panel.

[0026] 6. In a preferred embodiment of this application, in the second state, the angle between the swing arm and the radial direction of the pot body can be greater than or equal to 90°, so that the lid can be removed from the pot body in the up-down direction. An angle greater than or equal to 90° between the swing arm and the radial direction of the pot body ensures that the inner pot is completely open, providing ample operating space for placing ingredients and serving cooked food. Furthermore, the up-down removal of the lid conforms to the user's operating habits and avoids interference between the steam guide on the lid and the side wall of the inner pot during removal.

[0027] 7. As a preferred embodiment of this application, by providing a viewing window in the pot body and including a transparent inner liner that can be inserted into the pot body, the cooking appliance achieves visualization, allowing users to observe the cooking process of the ingredients through the viewing window and the transparent inner liner from the outside of the cooking appliance, resulting in a superior sense of participation and experience in cooking. Furthermore, since the operation display panel is located on the swing arm above the pot lid in this application, the operation display panel does not need to occupy the side space of the cooking appliance, greatly increasing the design space of the viewing window. This means the visible area of ​​the viewing window can be further increased compared to existing visual cooking appliances, thereby enhancing the visualization area and improving the user experience.

[0051] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0052] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0053] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0054] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0055] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0056] like Figures 1 to 14 The steam cooking appliance shown includes a pot body 1 and a lid 2 removably placed on the pot body 1. The cooking appliance also includes a swing arm 3, which is hinged to the pot body 1 to have... Figure 1 The first state shown is when the lid 2 is pressed tightly against the pot body 1, and... Figure 6The second state shown is rotated toward one side of the pot body 1 so that the lid 2 can be removed from the pot body 1; the pot body 1 is provided with a steam generating unit (not shown in the figure, which may be a steam generator, etc.), and the lid 2 is provided with a steam pipe assembly 21 that can communicate with the steam generating unit. In both the first and second states, the steam generating unit can provide steam to the cooking chamber of the steam cooking appliance through the lid 2.

[0057] In the steam cooking appliances provided in this application, such as Figures 1 to 3 As shown, the pressing state of the pot lid 2 by the swing arm 3 ensures that the pressing force applied by the swing arm 3 to the pot lid 2 during the cooking process can limit the pot lid 2 and counteract the lifting force caused by the rising steam, thus preventing the pot lid 2 from floating. This prevents steam from leaking out through the gap formed between the pot lid 2 and the pot body 1 due to the floating of the pot lid 2, and prevents hot soup from splashing out through the gap.

[0058] Furthermore, because the lid has a locking arm, if the user accidentally tries to open the lid during cooking, the arm will block it. Only by switching the arm from the first state to the second state can the lid be removed or placed, which adds a certain level of safety. Finally, since the steam generating unit can provide steam to the cooking chamber of the steam cooker through the lid in both the first and second states, even if the user accidentally switches the arm to the second state, there will be no possibility of a large amount of high-temperature steam escaping, eliminating the risk of burns.

[0059] In addition, the design of the swing arm 3 provides a basis for steam cooking appliances to use higher power and complete the cooking process of ingredients faster. Even when the output, rising speed and lifting pressure of steam in the cooking chamber increase under high power cooking conditions, the lid 2 can still maintain a stable closed state under the pressure of the swing arm 3.

[0060] In specific implementation, such as Figure 3 As shown, a steam guide 22, which connects to the steam pipe assembly 21 and extends into the cooking cavity, can also be provided on the lid 2 to conduct the steam generated by the steam generating unit into the cooking cavity through the steam pipe assembly 21 and the steam guide 22. In addition, a steam outlet 14 for releasing the steam generated by the steam generating unit is provided on the pot body 1, and a steam inlet 23 connecting to the steam pipe assembly 21 is provided on the lid 2. When the lid 2 is placed on the pot body 1, the steam inlet 23 is connected to the steam outlet 14, and the steam generating unit can supply steam into the steam pipe assembly 21.

[0061] The pot lid 2 described in this application is removably placed on the pot body 1, which means that the pot lid 2 and the pot body 1 are separate components. The pot lid 2 can be removed from the pot body 1 to open or close the pot body. This application does not limit the method of removing or placing the pot lid 2.

[0062] As one embodiment of this application, the pot lid 2 can be removed and placed from the pot body 1 in a vertical direction. The vertical removal and placement method is mainly due to the fact that the pot lid 2 is provided with a steam guide 22, which is mostly made of... Figure 3 The structural design shown is such that the steam guide 22 is symmetrically designed along its own axis. In order to maximize the steam delivery to the bottom of the cooking cavity, the bottom end of the steam guide 22 is usually close to the bottom of the cooking cavity, meaning the steam guide 22 is generally quite long. If the pot lid is opened by rotating it, it is easy to cause interference between the steam guide 22 and the inner wall of the cooking cavity. Shortening the length of the steam guide to avoid interference is not conducive to steam transmission. Therefore, the pot lid 2 used in this embodiment is removable from the pot body. While ensuring that the steam guide 22 has sufficient length, it can avoid interference between the steam guide 22 and the inner wall of the cooking cavity during the opening and closing of the pot lid 2.

[0063] In another embodiment of this application, the lid 2 and the pot body 1 are separate components, and the lid 2 can be opened or closed by rotating the lid 1. The pot body 1 is provided with an opening position and a steam docking position adapted to the lid 2. In the steam docking position, the cooking appliance can perform normal cooking. After cooking, the lid 2 can be rotated from the steam docking position to the opening position. In the opening position, the lid 2 can be removed by rotating the lid 2 or supported in the opening position after opening. In order to avoid interference between the steam guide and the inner wall of the cooking cavity during the rotation opening process, the structure of the steam guide can be reasonably designed. For example, at least a part of the steam guide on the side away from the opening position is designed to have an arc surface concentric with the rotation axis of the lid when it is flipped.

[0064] Regardless of which of the two embodiments described above is adopted, the removable lid 2 means that during normal cooking, when steam accumulates to a certain amount in the cooking cavity and its buoyancy overcomes the weight of the lid 2, the lid 2 tends to move upwards. Once the lid 2 floats, not only does the connection between the steam inlet 23 and the steam outlet 14 fail, causing steam to overflow from both points and resulting in heat loss, but the floating lid also allows steam to escape between the lid 2 and the pot body 1, reducing thermal efficiency. Therefore, by providing the swing arm 3, the lid 2 can be pressed against the pot body 1, preventing it from floating during cooking and ensuring heating efficiency.

[0065] As a preferred embodiment of this application, such as Figure 2 As shown, the swing arm 3 includes a horizontal part 31 and a connecting part 32. The connecting part 32 is hinged to the pot body 1. The horizontal part 31 is used to press the pot lid 2, and the horizontal part 31 is provided with an operation display panel 33.

[0066] The swing arm 3 includes a horizontal part 31 and a connecting part 32. The connecting part 32 is hinged to the pot body 1. The horizontal part 31 is used to press the pot lid 2, and the horizontal part 31 is provided with an operation display panel 33. This allows the swing arm 3 to not only press the pot lid 2 to limit its position, but also to realize the upward placement of the operation display panel 33. Compared with the traditional steam cooking appliance where the display panel is placed on the side of the pot body, it is more convenient for users to observe and operate the operation display panel 33. It also saves the design space on the side of the pot body 1, leaving more room for optimization design such as visualization, decoration, and atmosphere.

[0067] As a preferred embodiment of this implementation, such as Figure 3 and Figure 5 As shown, in the first state, there is a gap between the horizontal part 31 and the steam pipe assembly 21 to form an air layer 4 between the horizontal part 31 and the steam pipe assembly 21.

[0068] The presence of the air layer 4 not only improves the heat preservation effect but also achieves heat insulation, preventing the high temperature of the steam pipe assembly 21 from being transferred to the swing arm 3 through direct contact. This reduces the temperature rise of the swing arm 3 during cooking, ensuring the normal operation of the operation display panel 33. Furthermore, if the temperature rise of the swing arm 3 is low, it will be easier for the user to open the lid.

[0069] The method by which the swing arm 3 covers the steam pipeline assembly 21 is not specifically limited in this application:

[0070] In one specific embodiment of this application, the top surface of the steam pipe assembly is flush with the upper surface of the pot lid, and the swing arm has a main body extending in a horizontal direction, the main body of which wraps around the top surface of the steam pipe assembly. In this embodiment, the steam pipe assembly is located below the top surface of the pot lid, and the main body of the swing arm directly presses against the top surface of the pot lid to wrap around the steam pipe assembly.

[0071] In one specific embodiment of this application, at least a portion of the steam pipe assembly protrudes from the pot lid, and the swing arm has a main body extending in a horizontal direction, the main body wrapping around the top surface of the steam pipe assembly.

[0072] As a preferred embodiment of this application, such as Figure 6 As shown, at least a portion of the steam pipe assembly 21 protrudes from the pot lid 2, and the swing arm 3 includes a main body 34 extending horizontally and a flange 35 disposed around the periphery of the main body 34 and extending downward to wrap around the side of the steam pipe assembly 21.

[0073] By having the steam pipe assembly 21 protrude from the pot lid 2, the swing arm 3 includes a main body 34 extending horizontally and a flange 35 disposed around the periphery of the main body 34 and extending downwards. This allows the swing arm to not only wrap around the top surface of the steam pipe assembly 21 via the main body 34, but also around the side of the steam pipe assembly 2 via the flange 35. Therefore, the swing arm 3 has a larger wrapping area on the steam pipe assembly 21, resulting in better heat retention of the steam flowing through the steam pipe assembly 21, and further improving steam heating and cooking efficiency. Furthermore, the protruding design of the steam pipe assembly 21 also allows it to function as a handle for the user to grip, facilitating the removal and placement of the pot lid 2.

[0074] As a preferred embodiment of this implementation, such as Figure 3 As shown, the steam inlet 23 is located at the tail end of the steam pipe assembly 21, that is, at the tail end of the formed operating handle. This allows the steam pipe assembly 21 to not only function as an operating handle but also to directly connect with the steam outlet 14 when flipped to the first state, facilitating the flow of steam and avoiding the need for additional pipes to connect the steam pipe assembly 21 and the steam outlet 14, thus simplifying the structure of the pot lid 2.

[0075] It should be noted that, in this embodiment, the structure of the flanged portion 35 is not specifically limited, and it can be any of the following examples:

[0076] Example 1: In this example, the flange is a solid single-layer flange structure, which wraps around the side of the steam pipeline assembly.

[0077] Example 2: In this example, as Figure 4 and Figure 6 As shown, at least a portion of the flanged portion 35 is provided with a downward-opening mounting cavity 351. A light-emitting unit with a light-emitting function can be installed within this mounting cavity 351, giving the lid 2 a dazzling lighting effect when the cooking appliance is in cooking mode, enhancing its visual appeal and product competitiveness. Furthermore, the mounting cavity 351 also provides gap insulation, further reducing the temperature rise at the swing arm 3.

[0078] As a preferred embodiment of this implementation, such as Figure 4 and Figure 6 As shown, a handle position 352 is provided on the outer side of the flange 35. In the first state, there is a clearance gap between the handle position 352 and the pot lid 2. The handle position 352 and the clearance gap facilitate the user to put their hand into the clearance gap to rotate the arm by operating the handle position 352.

[0079] As a preferred embodiment of this implementation, such as Figure 5 and Figure 7 As shown, a buffer member 36 is provided on the side of the main body 34 facing the pot lid 2.

[0080] The buffer 36 serves two purposes: firstly, it prevents the swing arm 3 from rebounding after falling without buffering, reducing the vibration of the swing arm 3 and improving the installation reliability and service life of the electronic components inside the swing arm 3 corresponding to the operation display panel 33; secondly, it also prevents the swing arm 3 from directly colliding with the pot lid 2, which would cause scratches on each other and reduce the aesthetics.

[0081] As an alternative embodiment, a buffer element may be provided on the side of the steam pipe assembly 21 facing the main body 34, or buffer elements may be provided on both the side of the main body 34 facing the pot lid 2 and the side of the steam pipe assembly 21 facing the main body 34, to improve the buffering effect. The buffer element 36 includes, but is not limited to, silicone pads, airbag pads, polyethylene pads, etc.

[0082] It should be noted that this application does not specifically limit the driving method for the swing arm 3 to rotate on the pot body 1, and it can adopt any of the following embodiments:

[0083] Implementation method one: such as Figure 2 and Figure 3As shown, all the aforementioned embodiments and examples of this application can further include a first hinge seat 11 on the pot body 1 for hinged connection with the swing arm 3. The first hinge seat 11 also includes a first damping element 111, which causes the swing arm 3 to press against the pot lid 2. The first hinge seat 11 has a mounting groove for the first damping element 111 and a cover plate 112 that can open or close the mounting groove. In specific implementation, the rotation switching of the swing arm 3 between the first state and the second state needs to be manually achieved, that is, the rotation of the swing arm 3 from the first state to the second state and from the second state to the first state both need to be manually flipped.

[0084] Implementation Method Two: As a preferred implementation method, such as... Figure 8 As shown, all the foregoing embodiments and examples of this application can further include a limiting seat 5 in the cooking appliance, the limiting seat 5 being movably disposed on the pot body 1 to have a locked position and an unlocked position; as Figure 9 and Figure 10 As shown, in the locked position, the limiting seat 5 cooperates with the stop of the swing arm 3 to limit the swing arm 3 in the second state; as Figure 11 and Figure 12 As shown, in the unlocked position, the limiting seat 5 releases its restriction on the swing arm 3, allowing the swing arm 3 to switch from the second state to the first state; as Figure 8 and Figure 12 As shown, the pot lid 2 has a trigger part 24, and the limiting seat 5 has a mating part 51. When the pot lid 2 covers the pot body 1, the trigger part 24 drives the mating part 51 to move, and the limiting seat 5 switches from the locked position to the unlocked position.

[0085] The limiting seat 5, which is set on the pot body 1, has a locked position that limits the swing arm 3 to the second state and an unlocked position that releases the limitation on the swing arm 3. When the pot lid 2 closes the pot body 1, the limiting seat 5 switches from the locked position to the unlocked position. In other words, when the pot lid 2 is closed, the limiting seat 5 releases the limitation on the swing arm 3, and the swing arm 3 can automatically rotate from the second state to the first state that is pressed against the pot lid 2. Therefore, in the entire process of closing the lid, it is only necessary to close the pot lid 2 to realize the automatic closing of the swing arm 3, which saves the user's operation steps and also prevents the user from forgetting to close the swing arm 3, thus affecting the normal display and use of the display panel.

[0086] In specific implementation, such as Figure 8 and Figure 13As shown, a second hinge seat 12 can be provided on the pot body 1, which is hinged to the swing arm 3. The swing arm 3 is connected to the second hinge seat 12 via a pivot shaft 124. The second hinge seat 12 has a mounting position 121 for installing the limiting seat 5, realizing a partially concealed design of the limiting seat 5. Compared to the method of completely exposing it on the upper part of the pot body 1, a compact design is achieved through reasonable layout, and the upper part of the pot lid 2 does not appear bulky. In addition, as Figure 8 As shown, for the technical solution where the steam pipe assembly 21 protrudes from the pot lid, the trigger part 24 can also be set at the tail end of the steam pipe assembly 21, so that the steam pipe assembly 21 can not only serve as an operating handle for the user to hold and conveniently pick up and put down the pot lid 2, but also serve as a trigger for the mating part 51.

[0087] like Figure 8 and Figure 13 As shown, a second damping element 122 and a torsion spring 123 are provided on the second hinge seat 12. During the process of rotating the swing arm 3 to one side of the pot body 1, the torsion spring 123 assists the user in opening the swing arm 3, while the second damping element 122 impedes the rotation speed of the swing arm 3 in the later stages of rotation to prevent the machine from jumping. During the process of switching the swing arm 3 from the second state to the first state, at the beginning of rotation, the torsion spring 123 assists the swing arm 3 in rotating towards the pot lid 2, and the second damping element 122 prevents the swing arm 3 from falling rapidly. When the swing arm 3 moves to the first state, the torsion spring 123 and the second damping element 122, to a certain extent, hold the swing arm 3 in the first state and press the pot lid 2 firmly.

[0088] As a preferred embodiment of this implementation, such as Figure 10 , Figure 12 and Figure 14 As shown, the limiting seat 5 is provided with a limiting groove 52, and the swing arm 3 is provided with a limiting rib 37. In the locked position, the limiting rib 37 is inserted into the limiting groove 52 to restrict the rotation of the swing arm 3. In the unlocked position, the limiting rib 37 is disengaged from the limiting groove 52.

[0089] like Figure 12 As shown, when the limiting seat 5 moves toward the unlocked position, the limiting groove 52 disengages from the limiting rib 37, allowing the swing arm 3 to rotate; Figure 10 As shown, when the limiting seat 5 moves toward the locking position, the limiting groove 52 and the limiting rib 37 are inserted and engaged, thus limiting the rotation of the swing arm 3.

[0090] As an alternative embodiment, the limiting rib can also be set on the limiting seat 5 and the limiting groove can be set on the swing arm 3, which can achieve the same effect.

[0091] In a preferred embodiment of this implementation, in the second state, the angle between the swing arm 3 and the radial direction of the pot body 1 can be greater than or equal to 90°, so that the pot lid 2 can be removed from the pot body 1 in the up-down direction.

[0092] like Figure 9 As shown, the angle α between the swing arm 3 and the radial direction of the pot body 1 can be greater than or equal to 90° so that after the lid 2 is removed, the inner pot 7 is completely open, leaving ample operating space for placing ingredients and serving cooked food. Moreover, the up and down removal of the lid 2 not only conforms to the user's operating habits, but also avoids interference between the steam guide 22 set on the lid 2 and the side wall of the inner pot 7 during the removal process.

[0093] Furthermore, in this embodiment, the movement of the limiting seat 5 on the pot body 1 is not specifically limited, and it can adopt any of the following embodiments:

[0094] Example 1: In this example 1, the lid 2 is removed from the pot body 1 in the up-down direction, and the limiting seat 5 moves up and down relative to the pot body 1 to switch between the locked position and the unlocked position.

[0095] like Figure 12 As shown, after the pot lid 2 is placed on the pot body 1, the trigger part 24 presses down on the mating part 51, the limiting seat 5 moves down to the unlocked position and releases the restriction on the swing arm 3, and the swing arm 3 rotates to the first state where it is covered on the pot lid 2. Figure 10 As shown, when the swing arm 3 is rotated to the second state and the pot lid 2 is removed, the limiting seat 5 moves upward to the locking position and limits the swing arm 3 to a standing state perpendicular to the pot body 1. In specific implementation, the limiting seat 5 can be automatically moved upward by the spring 6 set between the hinge seat 11 and the limiting seat 5.

[0096] Example 2: In this example, the trigger part may be provided with a driving slope, the mating part may be provided with a driven slope, and the limiting seat may move laterally relative to the pot body to switch between the locked position and the unlocked position.

[0097] In practical implementation, for example, a barb can be provided on one of the limiting seat and the swing arm, and a hook groove can be provided on the other. When the pot lid is placed in place on the pot body, the triggering part moves the limiting seat laterally away from the pot body to the unlocked position through the cooperation of the driving inclined plane and the driven inclined plane. At this time, the barb disengages from the hook groove, the limiting seat releases its restriction on the swing arm, and the swing arm rotates to the first state where it is placed on the pot lid. When the swing arm is rotated to the second state and the pot lid is removed, the limiting seat moves laterally towards the pot body, and the barb engages with the hook groove to limit the swing arm to a standing state perpendicular to the pot body 1.

[0098] As a preferred embodiment of this application, such as Figure 3 As shown, all the aforementioned embodiments and examples of this application can further provide a viewing window 13 for the pot body 1, and the cooking utensil also includes a transparent inner liner 7 that can be placed inside the pot body 1.

[0099] By providing a viewing window 13 to the pot body 1, and including a transparent inner pot 7 that can be inserted into the pot body 1, the cooking appliance achieves visualization, allowing users to observe the cooking process of the ingredients through the viewing window 13 and the transparent inner pot 7 from the outside of the cooking appliance, resulting in a superior sense of participation and experience in cooking. Furthermore, since the operation display panel 33 is located on the swing arm 3 above the pot lid 2, it does not need to occupy the side space of the cooking appliance, greatly increasing the design space of the viewing window 13. This means the visible area of ​​the viewing window 13 can be further increased compared to existing visual cooking appliances, thereby enhancing the visualization area and improving the user experience.
