[0080] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0081] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0082] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0083] like Figures 1 to 4 As shown, the cooking device of this embodiment includes a pot body 10, a pot lid 20, and a steam box 30. The pot body 10 is used to hold food to be cooked. The pot lid 20 is mounted on the pot body 10. The steam box 30 is mounted on the pot lid 20 and includes a first cover 31 and a second cover 32 that interlock together, and a third cover 33 that is detachably mounted on the second cover 32. A locking structure is provided between the first cover 31 and the second cover 32 for locking the third cover 33 to the second cover 32.

[0084] Specifically, from Figure 7 It can be seen that the first cover 31 is a plate-like structure with a small annular side wall at the edge of the plate-like structure. Figure 9 It can be seen that the second cover 32 includes a bottom wall and an annular side wall provided at the edge of the bottom wall. The first cover 31 and the second cover 32 are buckled together. Furthermore, a mounting position for mounting a locking structure is provided on the second cover 32, and the locking structure is sandwiched between the first cover 31 and the second cover 32. Figure 5 and Figure 6 It can be seen that the third cover 33 is mounted on the surface of the second cover 32 facing away from the first cover 31. At the same time, the locking structure is used to fix the third cover 33 on the second cover 32.

[0085] like Figure 5 and Figure 6 ,as well as Figure 13 and Figure 14 As shown, in the technical solution of this embodiment, the locking structure includes a slider 40, which is movably disposed on the second cover 32. The third cover 33 is provided with a first latch 331 that engages with the slider 40. Specifically, the slider 40 is slidably disposed within the second cover 32. When the slider 40 slides to a position that engages with the first latch 331, the slider 40 can lock the third cover 33 to the second cover 32. When the slider 40 slides to a position separated from the first latch 331, the user can remove the third cover 33 from the second cover 32. Of course, the locking structure is not limited to the slider 40 and can also be other fixed structures, such as a fixed hook.

[0086] like Figures 16 to 18 As shown, in the technical solution of this embodiment, the slider 40 includes a snap-fit ​​portion 41 and an elastic portion 42 connected to the snap-fit ​​portion 41. The snap-fit ​​portion 41 and the elastic portion 42 are integrally structured and engage with the first latch 331. When the slider 40 is subjected to an external force and moves away from the first latch 331, the elastic portion 42 is compressed. When the slider 40 is no longer subjected to the external force, the elastic portion 42 releases its elastic force and returns the slider 40 to its original position. Specifically, in the prior art, the slider snap-fit ​​is often configured as follows: the slider snap-fit ​​includes a plastic snap-fit ​​and a spring. One end of the spring abuts the plastic part, and the other end abuts a rib, retaining rib, or a corresponding abutting structure. The spring provides elastic force to the plastic part. Because both the plastic snap-fit ​​and the spring are relatively small, assembly is difficult. Furthermore, the spring can easily pop out if not carefully observed, making it very easy to lose. In this embodiment, the buckle portion 41 and the elastic portion 42 are an integral structure. This structure allows the slider 40 to eliminate the need for a spring and prevents parts from being easily lost. Furthermore, the buckle portion 41 and the elastic portion 42 are an integral structure, that is, they are made through an integral molding process.

[0087] Of course, in an embodiment not shown, the buckling portion 41 and the elastic portion 42 may also be separate structures.

[0088] like Figure 16 and Figure 19 As shown, in the technical solution of this embodiment, the elastic portion 42 includes an elastic arm, a first end of the elastic arm is connected to the buckle portion 41, and a second end of the elastic portion 42 is arranged to abut against the side wall of the second cover body 32. Specifically, when the external force slide buckle 40 moves in a direction away from the first buckle 331, the elastic arm is compressed. When the external force disappears, the elastic arm releases the elastic potential energy, thereby causing the buckle portion 41 to move toward the first buckle 331 and reset. It should be noted that the above-mentioned external force can be the force applied to the slide buckle 40 by the user when it is toggled, or it can be the force applied to the slide buckle 40 by some mechanical structure, such as a solenoid valve, a push rod, a lever, etc.

[0089] Furthermore, in an embodiment not shown in the figure, the second end of the elastic arm may not be set in abutment with the side wall of the second cover body 32, or a retaining rib may be separately set on the inner surface of the second cover body 32, and the second end of the elastic arm may be set in abutment with the above-mentioned retaining rib.

[0090] like Figure 19 As shown, in the technical solution of this embodiment, the elastic arm is arranged at an angle to the straight line where the sliding buckle 40 moves. Specifically, the above-mentioned "straight line where the sliding buckle 40 moves" refers to: Figure 19 For example, Figure 19 The middle slider 40 moves in the left and right directions, and the above-mentioned straight line is Figure 19A straight line extending horizontally in the middle. That is, Figure 19 The elastic arm is arranged at an angle to the horizontal line. When the slider 40 moves in a direction away from the first buckle 331, the elastic arm is squeezed and deformed inwardly or outwardly, and the elastic arm stores elastic potential energy during the deformation process.

[0091] like Figures 16 to 18 As shown, in the technical solution of this embodiment, the elastic arm includes a first elastic arm 421 and a second elastic arm 422. In the direction away from the buckle 41, the distance between the first elastic arm 421 and the second elastic arm 422 gradually increases. Specifically, the ends of the first elastic arm 421 and the second elastic arm 422 are connected to the middle part of the buckle 41 after merging. The second ends of the first elastic arm 421 and the second elastic arm 422 are set to expand outward. The above-mentioned first elastic arm 421 and the second elastic arm 422 can provide a left-right symmetrical restoring force to the buckle 41, and make the buckle 41 receive the restoring force along the movement direction of the slider 40 as much as possible, and prevent the position of the slider 40 from being deflected. Furthermore, the first elastic arm 421 and the second elastic arm 422 are set in mirror symmetry.

[0092] Preferably, from Figure 17 and Figure 19 It can be seen that the ends of the first elastic arm 421 and the second elastic arm 422 are bent inward and then abut against the side wall of the second cover 32. The above structure makes the cooperation between the first elastic arm 421 and the side wall of the second cover 32, and the cooperation between the first elastic arm 421 and the side wall of the second cover 32, as two parallel surfaces, thereby making the operation of the mechanism more stable.

[0093] Preferably, to ensure that the first elastic arm 421 and the second elastic arm 422 can deform, the slider 40 should be made of a material with a certain degree of hardness and elasticity, such as plastic. At the same time, the cross-sectional area of ​​the first elastic arm 421 and the second elastic arm 422 should not be too small to prevent fatigue fracture of the first elastic arm 421 and the second elastic arm 422 after prolonged use. Furthermore, the angle between the first elastic arm 421 and the second elastic arm 422 should not be too large or too small. A too large angle will result in insufficient elastic force exerted by the first elastic arm 421 and the second elastic arm 422 on the buckle 41, while a too small angle will make it difficult for the first elastic arm 421 and the second elastic arm 422 to deform.

[0094] In this embodiment, the first elastic arm 421 and the second elastic arm 422 are both arranged at an angle. Of course, the extension direction of the first elastic arm 421 and the second elastic arm 422 can also be parallel to the straight line in which the slider 40 moves. Specifically, in an embodiment not shown, the elastic arm is wavy. Specifically, the wavy shape refers to the elastic arm being provided with multiple bends or curved structures. These bends and curved structures enable the elastic arm to be compressed when squeezed, and also serve to store elastic potential energy.

[0095] like Figure 17 and Figure 18 As shown, in the technical solution of this embodiment, the buckle 41 includes a plate body 411, the elastic part 42 is connected to the first edge of the plate body 411, and the second edge of the plate body 411 away from the first edge cooperates with the first buckle 331. Specifically, the plate body 411 is a rectangular plate structure, the first elastic arm 421 and the second elastic arm 422 are connected to one long side of the plate body 411, and the other long side of the plate body 411 forms a buckle. Figure 18 It can be seen that the lower surface of the edge of the plate body 411 opposite to the first elastic arm 421 and the second elastic arm 422 is provided with a guide slope, thereby facilitating the installation of the third cover 33. Preferably, a plurality of reinforcing ribs are provided on the upper surface of the plate body 411 to strengthen the structural strength of the plate body 411.

[0096] It should be noted that the aforementioned slider 40 is not limited to use within the steam box 30. Furthermore, the slider 40, as a snap-fit ​​or engaging structure, can be used in other locations within the cooking appliance. For example, the slider 40 can be used between the pot body 10 and the lid 20 as a lid-opening slider. When the slider 40 is used in other locations, a corresponding mounting position is provided within the cooking appliance, and the slider 40 is installed in the mounting position and engages with the structure to be engaged.

[0097] like Figure 9 As shown, in the technical solution of this embodiment, a first limiting structure 321 is provided on the second cover 32 , and the first limiting structure 321 fixes the slider 40 on the second cover 32 .

[0098] Specifically, if Figure 9 and Figure 19 as well as Figure 20As shown, the first limiting structure 321 includes a first limiting hook 3211 and a second limiting hook 3212 that are arranged opposite to each other, and the plate body 411 is arranged between the first limiting hook 3211 and the second limiting hook 3212. The hook portion of the first limiting hook 3211 and the hook portion of the second limiting hook 3212 are hooked on the surface of the plate body 411 that is away from the second cover body 32. The first limiting hook 3211 and the second limiting hook 3212 are arranged opposite to each other and are respectively located on both sides of the plate body 411. At the same time, the upper surface of the hook portion of the first limiting hook 3211 and the upper surface of the hook portion of the second limiting hook 3212 are both provided with guiding inclined surfaces, so that the first limiting hook 3211 and the second limiting hook 3212 are conveniently deformed outward when the plate body 411 is installed. Figure 20 It can be seen that when the plate body 411 is installed on the second cover body 32, the hook portion of the first limiting hook 3211 and the hook portion of the second limiting hook 3212 are respectively hooked on the upper surfaces on both sides of the plate body 411, thereby preventing the plate body 411 from falling off from the second cover body 32.

[0099] like Figure 7 As shown, in the technical solution of this embodiment, a second limiting structure 50 is provided on the first cover body 31. The second limiting structure 50 is provided on the surface of the first cover body 31 facing the second cover body 32. Specifically, the second limiting structure 50 includes a first limiting rib 51 and a second limiting rib 52. The first limiting rib 51 and the second limiting rib 52 are provided in parallel, and the first limiting rib 51 and the second limiting rib 52 are located above the slider 40. In this embodiment, the first limiting rib 51 and the second limiting rib 52 play a limiting role above the slider 40. Further, from Figure 9 and Figure 20 As can be seen, the plate 411 is restrained by the first and second restraining hooks 3211 and 3212. Since the hook portions of the first and second restraining hooks 3211 and 3212 are relatively small, when the slider 40 is pushed, it is possible for the slider 40 to twist around the first and second restraining hooks 3211 and 3212, potentially causing the first and second elastic arms 421 and 422 to disengage from the sidewalls of the second cover 32 and causing the slider 40 to fail. By providing the first and second restraining ribs 51 and 52, when the user pushes the slider 40, the slider 40 can only move slightly within the gap between the first and second covers 31 and 32, ensuring that the slider 40 functions properly.

[0100] It should be noted that, in order to ensure smooth sliding of the slider 40, in this embodiment, when the first cover 31 is mounted on the second cover 32, a certain gap is provided between the first limiting rib 51, the second limiting rib 52, and the slider 40. Of course, the second limiting structure 50 may also be provided with only one rib, or with two or more ribs.

[0101] like Figure 9 、 Figures 16 to 18 ,as well as Figure 22 As shown, in the technical solution of this embodiment, a first mounting opening 322 is provided on the second cover body 32, and the slider 40 further includes a dial button 43 provided on the plate body 411. The dial button 43 passes through the first mounting opening 322, and operating the dial button 43 can drive the slider 40 to slide. Specifically, the first mounting opening 322 is provided below the slider 40. The dial button 43 is a raised structure formed on the lower surface of the plate body 411. The dial button 43 passes downward through the first mounting opening 322, and the end of the dial button 43 is flush with the bottom surface of the second cover body 32 or protrudes from the bottom surface of the second cover body 32, thereby facilitating user operation and making the appearance of the product more beautiful. Preferably, from Figure 22 It can be seen that the width of the first mounting opening 322 is greater than the thickness of the dial button 43, that is, the dial button 43 can move back and forth in the first mounting opening 322, thereby driving the entire slider 40 to move back and forth. Furthermore, the width of the first mounting opening 322 also defines the sliding limit position of the slider 40.

[0102] like Figure 9 As shown, in the technical solution of this embodiment, a mounting boss 323 is provided on the inner surface of the bottom wall of the second cover 32, and the plate 411 is mounted on the mounting boss 323. The first mounting opening 322 is provided on the mounting boss 323. The slider 40 also includes a retaining rib 44 provided on the surface of the plate 411 facing the second cover 32. The retaining rib 44 is located outside the mounting boss 323. When the slider 40 moves to a position where the second edge of the plate 411 engages with the first latch 331, the retaining rib 44 abuts the sidewall of the mounting boss 323. Specifically, the inner surface of the bottom wall of the second cover 32 is raised inward to form the aforementioned mounting boss 323. The first retaining hook 3211 and the second retaining hook 3212 are respectively located on either side of the mounting boss 323. To install the slider 40, the dial button 43 is passed through the first mounting opening 322, and the plate 411 is placed on the upper surface of the mounting boss 323.

[0103] Further, from Figure 18 ,as well as Figure 21 and 22 As shown, the limiting rib 44 is provided on the lower surface of the plate 411. When the slider 40 is mounted on the mounting boss 323, the limiting rib 44 is located on the outer side of the side wall of the mounting boss 323. Figure 22 It can be seen that when the slider 40 moves to engage with the first buckle 331, the limiting rib 44 abuts against the side wall of the mounting boss 323, and the slider 40 cannot slide toward the first buckle 331. When the third cover 33 needs to be removed, the slider 40 can move away from the first buckle 331.

[0104] like Figure 14 and Figure 15 As shown, in the technical solution of this embodiment, a baffle 332 is provided on the third cover 33. The baffle 332 covers the mating surface between the first buckle 331 and the slider 40. Specifically, in the prior art, the covers of steam boxes are connected together by buckles or flexible arms, which are usually exposed on the outside of the steam box, thereby reducing the aesthetics of the steam box. In this embodiment, the baffle 332 blocks the mating surface between the first buckle 331 and the slider, thereby preventing the user from seeing the mating surface between the first buckle 331 and the slider 40 from the external surface of the steam box.

[0105] Furthermore, the third cover 33 is not limited to being used on the steam box 30. The third cover 33 can be installed as a mounting plate on other exterior surfaces of the cooking appliance. When the third cover 33 is installed in other locations, the baffle 332 can cover the connection surface of the connection structure, thereby achieving a concealing effect.

[0106] like Figure 15 As shown, in the technical solution of this embodiment, a recessed structure 333 is provided on the outer wall of the third cover body 33, and the upper side of the inner wall of the recessed structure 333 forms a first snap 331, and the portion of the third cover body 33 opposite to the first snap 331 forms a baffle 332. Specifically, a recessed structure 333 is provided on the outer surface of the side wall of the third cover body 33. When the third cover body 33 is installed, the end of the slider 40 extends into the recessed structure 333, and the slider 40 abuts and cooperates with the upper surface of the recessed structure 333, that is, the upper surface of the inner wall of the recessed structure 333 forms the first snap 331. Correspondingly, the surface of the recessed structure 333 opposite to the fastening surface of the first snap 331 forms the baffle 332. From Figure 15 It can be seen that the baffle 332 is a part of the bottom wall of the third cover 33. Figure 22 It can be seen that when the third cover body 33 is installed on the second cover body 32 , the baffle 332 blocks the mating surfaces of the first buckle 331 and the slider 40 , and the user cannot see them from the exterior surface of the steam box 30 .

[0107] like Figure 15 As shown, in the technical solution of this embodiment, a thickened portion 334 is provided at the edge of the third cover 33, and the recessed structure 333 is provided on the thickened portion 334. Specifically, the height of the thickened portion 334 is greater than the height of the third cover 33. This structure ensures the strength of the third cover 33 while facilitating the provision of the recessed structure 333. Of course, if both the thickness and height of the third cover 33 are sufficiently large, the thickened portion 334 may be omitted.

[0108] like Figure 5 and Figure 6As shown, in the technical solution of this embodiment, a receiving recess 324 is provided on the surface of the second cover 32 facing away from the first cover 31, and the third cover 33 is disposed within the receiving recess 324. Furthermore, the lower surface of the third cover 33 is flush with the lower surface of the second cover 32, thereby making the appearance of the steam box 30 more beautiful.

[0109] like Figure 12 As shown, in the technical solution of this embodiment, a second mounting opening 3241 is provided on the sidewall of the accommodating recess 324. A portion of the slider 40 passes through the second mounting opening 3241 and engages with the first latch 331. When the user toggles the dial button 43 and moves the slider 40 toward the first latch 331, the end of the plate 411 extends out of the second mounting opening 3241 and engages with the first latch 331. Correspondingly, when the user toggles the dial button 43 and moves the slider 40 away from the first latch 331, the end of the plate 411 retracts into the second mounting opening 3241.

[0110] like Figure 11 as well as Figure 13 As shown, in the technical solution of this embodiment, a socket 3242 is provided on the side wall of the accommodating recess 324, and an insert block 335 is provided on the side wall of the third cover 33, and the insert block 335 extends into the socket 3242. Specifically, there are two sockets 3242 and two insert blocks 335 accordingly. The installation process of the third cover 33 is as follows Figure 5 and Figure 6 As shown, first insert the insert block 335 into the socket 3242 , then pivot the third cover 33 downward and insert the third cover 33 into the accommodating recess 324 , and finally, the slide buckle 40 is buckled with the first buckle 331 .

[0111] like Figure 13 As shown, the insert block 335 and the first buckle 331 are arranged opposite to each other. Specifically, the first buckle 331 is arranged on the edge of the third cover 33 facing the slider 40, and the insert block 335 is arranged on the edge of the third cover 33 facing away from the slider 40.

[0112] like Figures 7 to 9As shown, in the technical solution of this embodiment, a boss structure 325 is formed in the second cover body 32 at a position corresponding to the accommodating recess 324, and a second clip 3251 is provided on the side wall of the boss structure 325. A first annular rib 311 is provided on the surface of the first cover body 31 facing the second cover body 32, and a first clamping platform 312 is provided on the first annular rib 311. When the first cover body 31 is installed on the second cover body 32, the first annular rib 311 is sleeved on the outside of the boss structure 325, and the second clip 3251 cooperates with the first clamping platform 312. Specifically, the lower surface of the second cover body 32 is recessed inward to form the above-mentioned accommodating recess 324, and accordingly, a boss structure 325 is formed on the inner side of the second cover body 32. The boss structure 325 protrudes inward from the bottom wall of the second cover body 32. From Figure 9 It can be seen that a second buckle 3251 is provided on the side wall of the boss structure 325. Figure 7 It can be seen that a first annular rib 311 is provided at a position of the first cover body 31 corresponding to the boss structure 325. Furthermore, the shape enclosed by the first annular rib 311 is adapted to the shape of the upper surface of the boss structure 325. At the same time, the area enclosed by the first annular rib 311 is slightly larger than the area of ​​the upper surface of the boss structure 325, so that the boss structure 325 can be accommodated in the area enclosed by the first annular rib 311. When the first cover body 31 and the second cover body 32 are buckled together, the boss structure 325 is accommodated in the area enclosed by the first annular rib 311, and the second clip 3251 is buckled on the first clip 312. The above structure fixes the middle part of the first cover body 31 and the second cover body 32 of the steam box 30, thereby ensuring the installation strength of the first cover body 31 and the second cover body 32.

[0113] Further, from Figure 22 It can be seen that when the first cover 31 and the second cover 32 are buckled together, the top surface of the boss structure 325 is in contact with the bottom wall of the first cover 31 .

[0114] like Figure 22 As shown, in the technical solution of this embodiment, a steam chamber 60 is formed between the third cover 33 and the accommodating recess 324. A steam inlet 336 is provided on the third cover 33, and an exhaust structure is provided on the accommodating recess 324. The exhaust structure connects the steam chamber 60 to the outside world. Specifically, when the cooking appliance is in operation, steam enters the steam chamber 60 through the steam inlet 336 and is then exhausted through the exhaust structure. The steam is buffered within the steam chamber 60, reducing its energy and thus reducing exhaust noise.

[0115] Preferably, the area ratio of the third cover 33 to the second cover 32 is less than or equal to 2: 1. The above structure can reduce the cleaning area for the user and prevent large-area deformation of the steam box 30.

[0116] Preferably, in the technical solution of this embodiment, the ratio of the projected area of ​​the steam chamber 60 on the surface of the first cover 31 to the surface area of ​​the first cover 31 is less than or equal to 1:5. Specifically, because the bottom wall of the first cover 31 is a plate of uniform thickness, the ratio of the projected area of ​​the steam chamber 60 on the horizontal plane to the surface area of ​​the bottom wall of the first cover 31 is less than or equal to 1:5. The above structure allows the heat of the steam to accumulate only in a small area of ​​the steam box 30 and prevents large-scale deformation of the first cover 31 and the second cover 32 due to heat, thereby ensuring the assembly effect and the aesthetics of the product. At the same time, the smaller steam chamber 60 also enables the steam box 30 to exhaust quickly.

[0117] like Figure 7 、 Figure 9 as well as Figure 22 As shown, in the technical solution of this embodiment, the exhaust structure includes an exhaust protrusion 3243, which is disposed on the bottom wall of the accommodating recess 324 and extends toward the first cover 31. An exhaust channel 3244 is provided on the exhaust protrusion 3243. The first cover 31 is provided with a relief hole 313. When the first cover 31 is placed on the second cover 32, the exhaust protrusion 3243 is inserted into the relief hole 313. Specifically, the exhaust protrusion 3243 is a columnar structure, with its lower end connected to the top wall of the boss structure 325 and its upper end extending toward the first cover 31. An exhaust channel 3244 is provided on the end surface of the exhaust protrusion 3243. The lower end of the exhaust channel 3244 communicates with the accommodating recess 324, and the upper end communicates with the outside world. The end of the exhaust protrusion 3243 is flush with the upper surface of the first cover 31. The above structure prevents steam and food juice from flowing into the first and second covers 31 and 32 through the gap between the first cover 31 and the upper surface of the boss structure 325, thereby preventing corrosion of parts such as the slider 40. Preferably, the cross-section of the exhaust protrusion 3243 and the avoidance hole 313 are both elongated structures.

[0118] like Figure 8 As shown, in the technical solution of this embodiment, a fastening structure 70 is provided between the first cover 31 and the second cover 32. The fastening structure 70 connects the first cover 31 and the second cover 32 together.

[0119] Specifically, if Figure 8 、 Figure 9 as well as Figures 21 to 24As shown, the fastening structure 70 includes a mounting hole 71, a connecting post 72, and a fastening screw 74. The mounting hole 71 is provided on the second cover 32. The connecting post 72 is provided on the first cover 31 and corresponds to the mounting hole 71. The connecting post 72 is provided with a connecting hole 73. The fastening screw 74 is inserted into the mounting hole 71 and the connecting hole 73. Furthermore, when the fastening screw 74 is screwed into the connecting hole 73, the inner wall of the connecting hole 73 is threaded.

[0120] like Figure 8 As shown, in the technical solution of this embodiment, a positioning structure 80 is provided between the first cover 31 and the second cover 32. Before the fastening screws 74 are installed, the first cover 31 and the second cover 32 are positioned by the positioning structure 80.

[0121] Specifically, if Figure 8 and Figure 10 As shown, the positioning structure 80 includes a third latch 81 and a second latch platform 82. The third latch 81 is disposed on the second cover 32. The second latch platform 82 is disposed on the first cover 31, and the second latch platform 82 is disposed correspondingly to the third latch 81. Specifically, there are multiple third latches 81 and multiple latch platforms 82. The third latch 81 is disposed on the inner side of the side wall of the second cover 32. The second latch platform 82 is disposed on the side wall of the first cover 31. The multiple third latches 81 and the multiple second latch platforms 82 are disposed in a one-to-one correspondence.

[0122] like Figure 4 As shown, in the technical solution of this embodiment, a sealing structure 90 is provided between the accommodating recess 324 and the third cover 33. The sealing structure 90 is used to seal the steam chamber 60.

[0123] like Figure 11 、 Figure 12 、 Figure 14 as well as Figure 22 As shown, in the technical solution of this embodiment, an annular groove 3245 is provided on the bottom wall of the accommodating recess 324, and a second annular rib 337 is provided on the surface of the third cover 33 facing the second cover 32. The sealing structure 90 includes a first sealing ring, which is disposed within the annular groove 3245. When the third cover 33 is installed in the accommodating recess 324, the second annular rib 337 abuts against the first sealing ring. When the third cover 33 is installed, the first sealing ring is disposed within the annular groove 3245, and then the third cover 33 is snapped into the accommodating recess 324. At this time, the second annular rib 337 abuts against the first sealing ring, causing the first sealing ring to be clamped and deformed, thereby greatly improving the sealing effect.

[0124] It should be noted that the annular groove 3245 of the present application is surrounded by two annular ribs, that is, the middle part of the two annular ribs forms the above-mentioned annular groove 3245. Of course, the annular groove 3245 can also be formed by the bottom of the accommodating recess 324 being recessed downward.

[0125] like Figure 25 and Figure 26 As shown, in the technical solution of this embodiment, the pot lid 20 includes an inner lining 21 and a cover 22 disposed on the inner lining 21. The cover 22 is provided with a mounting recess 221, and the steam box 30 is disposed within the mounting recess 221. The outer contour of the first cover 31 matches the outer contour of the upper surface of the cover 22, and the upper surface of the first cover 31 is flush with the upper surface of the cover 22. Specifically, in the prior art, the steam box structure is relatively small. Therefore, when the steam box is installed on the pot lid, there is a clear dividing line between the steam box and the cover, which makes the product look unsightly. In this embodiment, the outer contour of the first cover 31 matches the outer contour of the upper surface of the cover 22. Therefore, when the steam box 30 is installed on the cover 22, there is only a horizontal dividing line between the steam box 30 and the cover 22, which makes the cover more integrated and improves the aesthetics of the product.

[0126] like Figure 31 and 32 As shown, in the technical solution of this embodiment, a shielding rib 34 is provided at the edge of the steam box 30. Specifically, when the steam box 30 is placed on the mounting recess 221, a noticeable gap will appear between the steam box 30 and the sidewall of the mounting recess 221. The shielding rib 34 blocks the gap between the steam box 30 and the sidewall of the mounting recess 221, thereby enhancing the product's appearance. Specifically, the shielding rib 34 is provided at the edge of the first cover 31, and is located outside the edge of the first cover 31.

[0127] like Figure 7 、 Figure 25 as well as Figure 26 As shown, a relief notch 222 is provided at the edge of the upper surface of the face cover 22, and a gripping protrusion 314 is provided at the edge of the first cover 31. When the steam box 30 is placed in the mounting recess 221, the gripping protrusion 314 is positioned within the relief notch 222, and the end of the gripping protrusion 314 protrudes beyond the relief notch 222. Specifically, the outer contour of the gripping protrusion 314 is an arc-shaped surface that protrudes from the edge of the first cover 31. Because the upper surface of the first cover 31 is flush with the upper surface of the face cover 22, when removing the steam box 30, the user simply grasps the gripping protrusion 314 and flips it upward to remove the steam box 30. This structure facilitates the user's removal of the steam box 30.

[0128] like Figure 5 、 Figure 26and Figure 27 As shown, in the technical solution of this embodiment, the bottom wall of the mounting recess 221 includes a first protrusion 2211 and a first recess 2212 surrounding the first protrusion 2211. The lower surface of the bottom wall of the second cover 32 includes a second protrusion 326 and a second recess 327. The first protrusion 2211 and the second recess 327 are shaped to match each other. Specifically, in the prior art, to facilitate drainage of the bottom wall of the steam box, the bottom wall of the recess is also divided into a protrusion and a recess, with the protrusion and recess distributed on the left and right sides. Furthermore, for product aesthetics, the upper surface of the steam box is typically flush with the upper surface of the pot lid. This structure results in the protrusion portion of the bottom wall of the steam box located in the recess being thinner, while the recess portion of the bottom wall located in the recess is thicker. However, the thinner portion of the steam box is not convenient for installing the connecting structure, and the screw column is also short, resulting in poor installation strength in the thinner portion of the steam box. In this embodiment, since the first protrusion 2211 is located outside the first protrusion 2211, the second protrusion 326 is also located outside the second recess 327. This structure makes the circumferential thickness of the steam box 30 thicker, making it easier to install the third clip 81 and the second latch 82. At the same time, the length of the connecting column 72 is also longer, thereby ensuring the overall installation strength of the steam box 30.

[0129] Further, from Figure 6 As can be seen, the second raised portion 326 is provided with a plurality of raised points, which abut against the first recessed portion 2212. Since there is a large amount of condensed water on the bottom wall of the mounting recessed portion 221, the tension of the water may make it difficult to remove the steam box 30 after it contacts the bottom wall of the mounting recessed portion 221. Therefore, the raised points can reduce the contact area between the first recessed portion 2212 and the second raised portion 326, making it easier for the user to remove the steam box 30.

[0130] like Figure 1 as well as Figure 26 As shown, in the technical solution of this embodiment, the cooking utensil further includes a lid opening handle 100 provided on the pot lid 20, and the first protrusion 2211 is located on the first side of the bottom wall of the mounting recess 221 close to the lid opening handle 100. Specifically, the first protrusion 2211 is a roughly rectangular structure. Among them, one long side of the first protrusion 2211 coincides with the side wall of the mounting recess 221, so the first recess 2212 surrounds the three sides of the first protrusion 2211, that is, the first protrusion 2211 in this embodiment has a "U"-shaped structure. Of course, the first recess 2212 can also completely surround the first protrusion 2211. At the same time, the first protrusion 2211 can also be circular or other shapes.

[0131] like Figure 27 As shown, in the technical solution of this embodiment, the connecting surface between the first protrusion 2211 and the first recessed portion 2212 is an inclined surface, and the first recessed portion 2212 is provided with a water guide hole 223. Specifically, the stepped surface between the first protrusion 2211 and the first recessed portion 2212 is an inclined surface, allowing condensed water on the first protrusion 2211 to flow along the inclined surface into the first recessed portion 2212 and ultimately into the water guide hole 223. The water guide hole guides the condensed water into the water storage box.

[0132] like Figure 30 As shown, in the technical solution of this embodiment, the upper surface of the first protrusion 2211 and the upper surface of the first recessed portion 2212 are both inclined surfaces, so that water located on the first protrusion 2211 and the first recessed portion 2212 is guided into the water guide hole 223. Specifically, the above structure enables the condensed water on the first protrusion 2211 and the first recessed portion 2212 to flow into the water guide hole 223 through the inclined surfaces.

[0133] like Figure 28 As shown, in the technical solution of this embodiment, the cooking appliance further includes a pressure-limiting valve and a cooling rod 200 disposed within the pot lid 20. A first mounting hole 224 and a second mounting hole 225 are provided on the first raised portion 2211. The first mounting hole 224 is located above the pressure-limiting valve. The cooling rod 200 passes through the second mounting hole 225. The second recessed portion 327 is provided with a steam inlet 336 and a cooling air inlet 338. When the steam box 30 is installed within the mounting recessed portion 221, the steam inlet 336 engages with the first mounting hole 224, and the cooling air inlet 338 engages with the second mounting hole 225.

[0134] Specifically, the pressure-limiting valve and the cold air rod 200 are both located on the inner liner 21. The pressure-limiting valve cooperates with the exhaust pipe and is used to limit the cooking pressure of the cooking appliance. The cold air rod 200 is used to discharge the cold air within the pot body 10 when cooking begins. Due to their high height, the pressure-limiting valve and the cold air rod 200 need to be located higher within the mounting recess 221. Therefore, the first mounting hole 224 and the second mounting hole 225 are both located on the first raised portion 2211. Correspondingly, the accommodating recess 324 of the steam box 30 is located within the second recess 327 of the second cover 32, and the third cover 33 is correspondingly located within the second recess 327. When the cooking appliance is in operation, steam within the pot body 10 passes through the exhaust pipe and then enters the steam chamber 60 through the first mounting hole 224 and the steam inlet 336. Correspondingly, the cold air in the pot body 10 passes through the cold air rod, and then passes through the second mounting through hole 225 and the cold air inlet 338 and enters the steam chamber 60 .

[0135] like Figure 28 As shown, in the technical solution of this embodiment, the cooking appliance further includes a second sealing ring 300 disposed within the first mounting hole 224. A connecting sleeve 339 is provided at the steam inlet 336. The connecting sleeve 339 extends toward the cover 22. When the steam box 30 is installed in the mounting recess 221, the connecting sleeve 339 is inserted into the second sealing ring 300. Specifically, the second sealing ring 300 forms an interference fit with the first mounting hole 224, and the connecting sleeve 339 forms an interference fit with the second sealing ring 300. This structure prevents condensed water generated by steam from flowing between the steam box 30 and the bottom wall of the mounting recess 221.

[0136] Preferably, the cooking appliance in this embodiment is an electric pressure cooker or an electric rice cooker.

[0137] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0138] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0139] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures".
