Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and particularly to a cooking appliance. Background Art

[0002] Currently, since the inner pot or inner liner in some cooking appliances is not detachable, such as small cooking pots, electric hot pots, food processors, etc., and the outer shells of such cooking appliances are provided with heat dissipation holes for dissipating heat of electrical components. Therefore, when cleaning the inner pot or inner liner, it is often necessary to place the whole machine in a sink, which causes liquids, impurities, etc. in the sink to easily flow into the cooking appliance through the heat dissipation holes, not only polluting the internal structure of the cooking appliance, but also even having a short - circuit impact. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a cooking appliance that can open or close the heat dissipation holes according to actual needs, so that when the cooking appliance is working, the heat dissipation holes are in an open state to achieve heat dissipation, and when cleaning the cooking appliance, the heat dissipation holes are in a closed state to prevent liquids, impurities, etc. from entering the interior of the cooking appliance, overcoming the deficiency that the existing cooking appliances with heat dissipation holes for electrical components cannot be directly rinsed, and providing a cooking appliance with a waterproof function.

[0004] A cooking appliance includes a bottom shell, an inner pot, and a heating component. The inner pot is fixedly arranged on the bottom shell, and an assembly space is provided between them. The heating component is arranged in the assembly space. The bottom shell is provided with heat dissipation holes communicating with the assembly space. The cooking appliance further includes a sealing component. The sealing component includes a sealing baffle, a driving member, and a transmission unit. The transmission unit is connected between the driving member and the sealing baffle. Both the sealing baffle and the transmission unit are arranged in the assembly space, and the driving member is arranged outside the assembly space. The sealing baffle has a first position and a second position. The driving member can drive the sealing baffle to switch between the first position and the second position through the transmission unit. In the first position, the sealing baffle blocks the heat dissipation holes, and in the second position, the sealing baffle releases the blockage to open the heat dissipation holes.

[0005] It can be understood that the heating component heats the inner pot to cook the ingredients, and the heat dissipation holes are used to dissipate heat from the bottom shell to reduce the impact of overheating of the bottom shell. When used for cleaning the inner pot, the driving member drives the sealing baffle to move to the position of blocking the heat dissipation hole through the transmission unit to prevent the liquid, impurities, etc. in the water tank from entering the assembly space through the heat dissipation hole, thereby alleviating the impact of the short circuit. Moreover, the sealing baffle can also move to the second position under the action of the driving member and the transmission unit to release the blockage of the heat dissipation hole, and the heat dissipation hole connects the assembly space and the external environment for normal heat dissipation needs. Therefore, the cooking utensil provided in the present application utilizes the movement of the sealing baffle relative to the bottom shell to adjust the position of the sealing baffle relative to the heat dissipation hole, and then switches the connection state at the heat dissipation hole, which is compatible with heat dissipation and cleaning and waterproofing needs. Moreover, since the sealing baffle and the transmission unit are both located in the assembly space, damage to both caused by external liquids, impurities, etc. can be avoided, especially the protection of the transmission unit is improved, and the problem that the transmission unit is easily corroded or plugged by impurities and affects the transmission effect is alleviated as much as possible; and the driving member is arranged outside the assembly space for easy user operation.

[0006] In some embodiments, the driving member is arranged on the outer side of the bottom of the bottom shell, the driving member includes a column and an operating part arranged on the column, the operating part is located outside the assembly space, and the column is connected to the transmission unit; the bottom shell is provided with a penetration hole for the column to penetrate, a sealing ring is provided between the column and the hole wall of the penetration hole, and a support foot is provided at the bottom of the bottom shell, and the operating part does not protrude from the support foot.

[0007] Such a setting ensures the sealing of the connection between the column and the bottom shell on the basis of satisfying the rotational drive of the sealing baffle, thereby preventing liquid from seeping in from the gap between the two; and ensures the stability of the bottom shell when it is placed, thereby preventing it from tilting due to the external placement of the operating part.

[0008] In some embodiments, the bottom shell is provided with a fixed column, and the sealing baffle is rotatably mounted on the fixed column to switch between the first position and the second position; in the first position, the sealing baffle at least partially overlaps with the heat dissipation hole to seal it; in the second position, the sealing baffle is offset from the heat dissipation hole to release the blockage.

[0009] That is to say, the sealing baffle is switched between the first position and the second position by rotating the sealing baffle relative to the fixed column, thereby achieving the blocking and opening of the heat dissipation hole; and, such an arrangement does not occupy too much vertical installation space, thereby avoiding interference of the sealing baffle with the assembly of the inner pot and the heating component.

[0010] In some of these embodiments, a limiting baffle is provided at one end of the fixed post away from the bottom case; the sealing member further includes an elastic member, the elastic member is disposed between the limiting baffle and the sealing baffle, and the sealing baffle has a tendency to press towards the bottom case under the action of the elastic member.

[0011] It can be understood that the arrangement of the elastic member prompts the sealing baffle to always press towards the bottom case, so as to ensure the pressing degree between the sealing baffle and the bottom case in the first position and improve the sealing effect.

[0012] In some of these embodiments, one of the bottom case and the sealing baffle is concavely provided with an avoidance groove, and the other is convexly provided with a top contact protrusion; in the first position, the top contact protrusion is received in the avoidance groove, and the bottom case and the sealing baffle are in surface contact; in the second position, the top contact protrusion moves out of the avoidance groove, and there is a gap between the bottom case and the sealing baffle.

[0013] That is to say, the avoidance groove can receive the top contact protrusion in the first position to ensure that the sealing baffle is fully pressed against the bottom case and improve the sealing performance; and when switching to the second position, the top contact protrusion can be used to reduce the contact area between the sealing baffle and the bottom case and reduce wear.

[0014] In some of these embodiments, the avoidance groove and the top contact protrusion are in spherical cooperation; and / or, a plurality of top contact protrusions are provided and arranged at intervals around the axis of the fixed post, and each top contact protrusion is correspondingly provided with an avoidance groove.

[0015] It can be understood that the spherical cooperation method is more conducive to the top contact protrusion moving into and out of the avoidance groove, and the operation is smoother; and, a plurality of top contact protrusions cooperate to improve the support effect and ensure balanced force.

[0016] In some of these embodiments, the transmission unit adopts a gear transmission unit, and / or, the driving member adopts a handwheel. In this way, the transmission ratio can be changed by using different numbers of teeth, and the transmission is more stable and reliable; and, the handwheel is more convenient for the user to hold and operate.

[0017] In some of these embodiments, the sealing baffle includes a connecting portion and a shielding portion provided on the connecting portion, the connecting portion is sleeved on the fixed post, and is provided with a plurality of meshing teeth arranged at intervals around the axis of the fixed post; the transmission unit includes a transmission gear, the transmission gear is connected to the driving member, and is meshed and transmitted with the connecting portion through the meshing teeth.

[0018] In this way, the meshing teeth can be directly machined on the sealing baffle, thereby reducing the number of gears that need to be assembled and simplifying the structure.

[0019] In some embodiments, the sealing component further includes a sealing member disposed on the sealing baffle; in the first position, the sealing member is pressed between the sealing baffle and the bottom shell and is disposed around the periphery of the heat dissipation hole. It can be understood that the sealing member is used to further improve the sealing performance when the two are pressed together.

[0020] In some embodiments, the sealing component further comprises a cover plate, which is arranged on a side of the sealing baffle away from the bottom shell, and the sealing member is limited between the sealing baffle and the cover plate, and partially protrudes from the cover plate. It can be understood that the cover plate and the sealing baffle cooperate to improve the connection reliability of the sealing member and avoid the sealing member from being loosened due to frequent rotation.

[0021] In some embodiments, the bottom shell is provided with a first limiting portion and a second limiting portion, which are arranged at an interval; the first limiting portion cooperates with the sealing component to limit the sealing baffle to the first position, and the second limiting portion cooperates with the sealing component to limit the sealing baffle to the second position.

[0022] That is to say, by utilizing the arrangement of the first limiting portion and the second limiting portion, the sealing baffle can be reminded of being in place at the first position and the second position, and the operation is more precise, so that both the sealing effect and the heat dissipation effect are guaranteed without affecting each other.

[0023] In some embodiments, at least one of the first limiting part and the second limiting part adopts a limiting column, and the limiting column is used to abut against the sealing baffle for limiting. It can be understood that the abutment and limiting of the limiting column and the sealing component can realize a mechanical structure-type in-place reminder, which is easy to manufacture and simplifies the structure.

[0024] In some of the embodiments, the heat dissipation holes are provided in a plurality of groups and are arranged at intervals around the central axis of the bottom shell; the sealing baffle has a plurality of shielding portions arranged at intervals around the central axis, and each group of the heat dissipation holes corresponds to one shielding portion.

[0025] It can be understood that multiple groups of heat dissipation holes provide heat dissipation effects, so multiple shielding parts are used to correspond to the multiple groups of heat dissipation holes one by one, respectively, to achieve blocking at each group of heat dissipation holes, thereby improving the sealing effect.

The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the related listed items.

[0042] In the related art, cooking appliances such as small cooking pots, electric hot pots, cooking machines, electric cookers, etc. generally include a bottom shell and an inner pot (or inner liner, hereinafter referred to as the inner pot) fixedly arranged on the bottom shell. A heating component is arranged at the bottom of the inner pot to heat food materials for cooking. Since most of the bottom shells are made of materials such as plastics and resins, they are easily affected by heat. Therefore, the bottom shell is usually provided with heat dissipation holes for dissipating the heat transferred to the bottom shell to avoid overheating of the bottom shell. At the same time, most of these cooking appliances adopt the method of fixedly arranging the inner pot and the bottom shell, that is, the inner pot is not detachable relative to the bottom shell. Therefore, when cleaning the inner pot after cooking, the whole cooking appliance needs to be placed in a sink. As a result, liquids, cleaning impurities, etc. in the sink are very likely to flow into the interior of the cooking appliance through the heat dissipation holes on the bottom shell, not only polluting the internal structure of the cooking appliance, but even causing a short circuit in the internal electrical structure.

[0043] In view of this, an embodiment of the present application provides a cooking appliance that can open or close the heat dissipation holes according to actual needs (i.e., cleaning needs, cooking needs, etc.), reduce the liquids, impurities, etc. flowing into the interior through the heat dissipation holes during cleaning, and ensure normal heat dissipation during cooking. The structure of this cooking appliance will be described in detail below.

[0044] Please refer to Figures 1 to 6 , for example, this cooking appliance includes a bottom shell 10, an inner pot 20 and a heating component 50. The inner pot 20 is fixedly arranged on the bottom shell 10 and an assembly space 101 is provided between the two. The heating component 50 is arranged in the assembly space 101 for heating the inner pot 20. The bottom shell 10 is provided with heat dissipation holes 102 communicating with the assembly space 101. This cooking appliance further includes a sealing component 30, and the sealing component 30 is movably arranged on the bottom shell 10. The sealing component 30 has a first position and a second position. In the first position, the sealing component 30 blocks the heat dissipation holes 102, and in the second position, the sealing component 30 releases the blockage to open the heat dissipation holes 102.

[0045] It can be understood that the heating component 50 heats the inner pot 20 to cook the ingredients, and the heat dissipation holes 102 are used to dissipate heat from the bottom shell 10 to reduce the overheating effect of the bottom shell 10. Since the sealing component 30 can block the heat dissipation holes 102 when it is in the first position, the assembly space 101 is blocked from being connected to the external environment. Therefore, when used to clean the inner pot 20, the sealing component 30 is used to block the heat dissipation holes 102 to prevent the liquid, impurities, etc. in the sink from entering the assembly space 101 through the heat dissipation holes 102, thereby reducing pollution to the internal structure, alleviating the impact of short circuits, and improving the waterproofness of the entire machine. Moreover, during normal cooking, the sealing component 30 can also move to the second position to release the blockage of the heat dissipation holes 102, and the heat dissipation holes 102 connect the assembly space 101 and the external environment for normal heat dissipation needs. Therefore, the cooking utensil provided in this embodiment utilizes the movable setting of the sealing component 30 relative to the bottom shell 10 to adjust the position of the sealing component 30 relative to the heat dissipation hole 102, and then switch the connectivity state of the heat dissipation hole 102 (i.e., the blocked state and the open state), thereby being compatible with the heat dissipation and cleaning and waterproofing requirements.

[0046] The sealing component 30 includes a sealing baffle 31, a driving member 33 and a transmission unit 34. The transmission unit 34 is connected between the driving member 33 and the sealing baffle 31. The sealing baffle 31 and the transmission unit 34 are both arranged in the assembly space 101. The driving member 33 is arranged on the side of the bottom shell 10 away from the assembly space 101 (i.e., outside the assembly space 101). The first position and the second position of the aforementioned sealing component 30 are the first position and the second position of the sealing baffle 31. The driving member 33 can drive the sealing baffle 31 to switch between the first position and the second position through the transmission unit 34. In the first position, the sealing baffle 31 blocks the heat dissipation hole 102, and in the second position, the sealing baffle 31 is unblocked to open the heat dissipation hole 102. In other words, the transmission unit 34 can be used to transmit the force applied by the driving member 33 to the sealing baffle 31, so that the sealing baffle 31 can be rotated, and the operation is smoother and more convenient. Since the sealing baffle 31 and the transmission unit 34 are both located in the assembly space 101, they can be prevented from being damaged by external liquids, impurities, etc., and in particular, the protection of the transmission unit 34 is improved, and the problem that the transmission unit 34 is easily corroded or blocked by impurities and affects the transmission effect is alleviated as much as possible; and since the driving member 33 is arranged outside the assembly space 101, it is convenient for users to operate.

[0047] In some specific embodiments, the driving member 33 is disposed outside the bottom of the bottom case 10. The driving member 33 includes a column 332 and an operating portion 331 disposed on the column 332. The operating portion 331 is located outside the assembly space 101, and a part of the column 332 passes through the bottom case 10 to connect to the transmission unit 34. The operating portion 331 is used for the user to hold and rotate, thereby driving the transmission unit 34 to act through the column 332, and then transmitting the power to the sealing baffle 31 through the transmission unit 34. Such an arrangement can satisfy the transmission connection and power transmission when the driving member 33 and the transmission unit 34 are arranged on opposite sides of the bottom case 10, and thus realize the driving of the sealing baffle 31. Among them, the bottom case 10 is provided with a through hole for the column 332 to pass through, and a sealing ring is provided between the column 332 and the hole wall of the through hole. On the basis of satisfying the driving of the sealing baffle 31, the connection sealing performance between the column 332 and the bottom case 10 is ensured, and liquid is prevented from seeping in from the gap between the two.

[0048] Furthermore, the bottom of the bottom case 10 needs to be provided with feet 15, and the operating portion 331 does not protrude beyond the feet 15, ensuring that the bottom case 10 is stably supported by the feet 15 when placed, and reducing the interference of the external placement of the operating portion 331 on the bottom case 10. That is to say, the bottom case 10 is elevated by the feet 15, so that there is sufficient space at the bottom of the bottom case 10 for the assembly and movement of the driving member 33. Among them, there are multiple feet 15, which are evenly spaced around the central axis of the bottom case 10, improving the support stability and ensuring balanced force.

[0049] For example, the driving member 33 is a handwheel, which is more convenient for the user to hold and operate.

[0050] Still further, the transmission unit 34 is a gear transmission unit. That is to say, the movement of the sealing baffle 31 is realized by means of gear transmission. Since the gear transmission can change the transmission ratio by using gears with different numbers of teeth, the movement speed of the sealing baffle 31 can be adjusted, ensuring not only stable and reliable transmission, but also timely and convenient operation. At this time, since the transmission unit 34 is disposed in the assembly space 101, the gears can be prevented from contacting external impurities and cleaning liquids, thereby reducing the corrosion of the gears, and also avoiding as much as possible the problem that the gears are affected by the jamming of impurities and cannot rotate or are stuck. The subsequent transmission connection between the transmission unit 34 and the sealing baffle 31 will be described in detail.

[0051] Please refer to Figures 1 to 5, optionally, the bottom case 10 is provided with fixing posts 11, and the sealing baffle 31 is rotatably sleeved on the fixing posts 11 to switch between a first position and a second position. In the first position, the sealing baffle 31 at least partially coincides with the heat dissipation holes 102 to block them; in the second position, the sealing baffle 31 is offset from the heat dissipation holes 102 to release the blockage. That is to say, by rotating the sealing baffle 31 relative to the fixing posts 11 to switch between the first position and the second position, the blockage and opening of the heat dissipation holes 102 are realized; and such a setting does not occupy too much installation space in the vertical direction and avoids interference in the assembly of the inner pot 20 and the heating component 50 caused by the setting of the sealing baffle 31.

[0052] As Figure 1 , Figure 2 , Figure 8 and Figure 9 shown, in some specific embodiments, the fixing posts 11 are arranged in the middle of the bottom case 10. At this time, the central axis of the fixing posts 11 is the central axis of the bottom case 10, and the heat dissipation holes 102 are arranged on the outer periphery of the fixing posts 11. The sealing baffle 31 includes a connecting portion 311 and a shielding portion 312, which are connected. The connecting column 21 is provided with a second sleeving hole 3113, and the fixing post 11 passes through the second sleeving hole 3113 to satisfy the rotational connection between the connecting portion 311 and the fixing post 11. By using the rotation of the connecting portion 311 around the axis of the fixing post 11 (i.e., the central axis of the fixing post 11), the shielding portion 312 is driven to rotate synchronously to realize the blockage and release of the blockage of the heat dissipation holes 102.

[0053] Alternatively, the sealing baffle 31 can also be slidably connected to the fixing post 11 and lifted and lowered along the axial direction of the fixing post 11. For example, when the sealing baffle 31 rises, the blockage is released to open the heat dissipation holes 102, and when the sealing baffle 31 descends, the heat dissipation holes 102 are blocked.

[0054] In some specific embodiments, taking the rotational sealing of the sealing baffle 31 as an example. The sealing baffle 31 includes a connecting portion 311 and a shielding portion 312 arranged on the connecting portion 311. The connecting portion 311 is sleeved on the fixing post 11, and the connecting portion 311 is provided with a plurality of meshing teeth 3111 arranged at intervals around the axis of the fixing post 11 (i.e., the central axis of the fixing post 11); the transmission unit 34 includes a transmission gear 341, the transmission gear 341 is connected to the driving member 33 and meshes and transmits with the connecting portion 311 through the meshing teeth 3111.

[0055] That is to say, the meshing teeth 3111 can be directly machined on the sealing baffle 31 to cooperate with the transmission gear 341, reducing the number of gear assemblies in the entire sealing component 30 and simplifying the structure. Among them, the meshing teeth 3111 are provided on the part of the connecting portion 311 located between any two adjacent shielding portions 312, so that the transmission gear 341 is located in the area between the two shielding portions 312, improving the structural compactness. The diameter of the connecting portion 311 is larger than the diameter of the transmission gear 341.

[0056] Alternatively, the transmission unit 34 may also include two transmission gears, one of which is connected to the driving member 33, and the other transmission gear is coaxially arranged and connected to the connecting portion 311. Another alternative is that the transmission unit 34 may also adopt belt drive, one of the belt pulleys is coaxially arranged and connected to the connecting portion 311, and the other belt pulley is connected to the driving member 33, and the two belt pulleys tension the transmission belt. Or, the transmission unit 34 adopts chain drive, etc. Here is only an example for illustration.

[0057] Such as Figures 2 to 6 As shown, further, there are multiple groups of heat dissipation holes 102, which are arranged at intervals around the central axis of the bottom case 10. Among them, each group of heat dissipation holes 102 includes one heat dissipation hole 102, or may also include two or more heat dissipation holes 102. The sealing baffle 31 in the sealing component 30 has multiple shielding portions 312 arranged at intervals around the central axis, and each group of heat dissipation holes 102 corresponds to one shielding portion 312. The multiple groups of heat dissipation holes 102 are evenly distributed at intervals around the central axis, improving the heat dissipation effect and heat dissipation uniformity. The multiple heat dissipation holes 102 in each group are all arranged in an arc shape around the central axis, and the multiple heat dissipation holes 102 are evenly distributed from the inside to the outside and from short to long at intervals. The outer contour of each group of heat dissipation holes 102 is in a fan-shaped ring shape. Correspondingly, each shielding portion 312 is also in a fan-shaped ring shape, and each shielding portion 312 corresponds to a group of heat dissipation holes 102. Such a setting improves the adaptability between the two, not only ensuring sufficient blocking of the heat dissipation holes 102 during cleaning, but also ensuring that there is no interference with the heat dissipation area of the heat dissipation holes 102 when the blocking is released, so that each heat dissipation hole 102 is fully exposed. Among them, the multiple shielding portions 312 are all connected to the connecting portion 311.

[0058] During actual use, the blank area between any two adjacent groups of heat dissipation holes 102 is used for temporary storage when the shielding portion 312 is released from the block. It can be that the maximum arc length of the blank area around the central axis is greater than the maximum arc length of each group of heat dissipation holes 102 around the central axis, ensuring that the shielding portion 312 of the sealing baffle 31 does not block the heat dissipation range of the heat dissipation holes 102 when the shielding is released.

[0059] In some specific embodiments, the bottom case 10 is provided with two groups of heat dissipation holes 102, which are spaced 180 degrees apart and correspond to two shielding portions 312. Alternatively, the bottom case 10 is provided with three groups of heat dissipation holes 102, which are spaced 120 degrees apart and correspond to three shielding portions 312. Alternatively, the bottom case 10 is provided with four groups of heat dissipation holes 102, which are spaced 90 degrees apart and correspond to four shielding portions 312. This is only an example setting.

[0060] Please combine Figure 2 , Figure 7 , Figure 8 and Figure 9 In actual use, the sealing component 30 also includes a sealing member 35 arranged on the sealing baffle 31; in the first position, the sealing member 35 is pressed between the sealing baffle 31 and the bottom shell 10, and is arranged around the outer periphery of the heat dissipation hole 102. That is to say, when the sealing baffle 31 is pressed on the bottom shell 10, the sealing member 35 is deformed by force to form a sealing area around the outer periphery of the heat dissipation hole 102, thereby increasing the sealing performance at the heat dissipation hole 102, further reducing the infiltration of liquid or impurities, and improving the protective performance. Among them, each shielding portion 312 on the sealing baffle 31 is provided with an independent sealing member 35 to ensure the sealing requirements of each group of heat dissipation holes 102. As mentioned above, the outer contour of each group of heat dissipation holes 102 is arranged in a fan-shaped ring shape, and the outer contour of the sealing area formed by each sealing member 35 is in a fan-shaped ring shape.

[0061] Alternatively, a plurality of groups of heat dissipation holes 102 may also share a sealing member 35 , which mainly forms a sealing area around the periphery of each group of heat dissipation holes 102 .

[0062] Furthermore, the sealing component 30 further includes a cover plate 36, which is disposed on a side of the sealing baffle 31 away from the bottom shell 10, and the sealing member 35 is limited between the sealing baffle 31 and the cover plate 36, and partially protrudes from the cover plate 36. Specifically, each shielding portion 312 on the sealing baffle 31 is concavely provided with a first concave cavity 3101, and the sealing member 35 is configured in a structure adapted to the shielding portion 312 and is configured with a second concave cavity 3501. The sealing member 35 is accommodated in the first concave cavity 3101, and the cover plate 36 is accommodated in the second concave cavity 3501, and is pressed on a side of the sealing member 35 away from the shielding portion 312, so that a part of the side portion 351 of the sealing member 35 protrudes from the cover plate 36. In this way, when the sealing baffle 31 is pressed against the bottom shell 10 to block the heat dissipation hole 102, the protruding portion of the side portion 351 is pressed between the sealing baffle 31 and the bottom shell 10 to improve the sealing effect; and, the cover plate 36 and the sealing baffle 31 are used to cooperate to improve the connection reliability of the seal 35 to avoid the seal 35 from loosening due to frequent rotation.

[0063] The sealing baffle 31, each sealing member 35 and each corresponding cover plate 36 are all fastened by screws. Of course, they can also be fixed by bonding.

[0064] Please combineFigures 3 to 5 Optionally, the bottom case 10 is provided with a first limiting portion 13 and a second limiting portion 14, which are arranged at intervals; the first limiting portion 13 cooperates with the sealing member 30 to limit the sealing baffle 31 at the first position; the second limiting portion 14 cooperates with the sealing member 30 to limit the sealing baffle 31 at the second position. Wherein, the first limiting portion 13 and the second limiting portion 14 may be arranged at intervals along the moving direction of the sealing baffle 31. Taking the rotation of the sealing baffle 31 as an example, the first limiting portion 13 and the second limiting portion 14 are arranged at intervals around the axis of the fixed column 11. When the first limiting portion 13 cooperates with the sealing baffle 31, it meets the in-place reminder for the sealing baffle 31 to rotate to the first position; when the second limiting portion 14 cooperates with the sealing baffle 31, it meets the in-place reminder for the sealing baffle 31 to rotate to the second position. In this way, the rotation operation accuracy of the sealing baffle 31 is improved, ensuring both the sealing effect and the heat dissipation effect, and they do not affect each other.

[0065] In some specific embodiments, both the first limiting portion 13 and the second limiting portion 14 are limiting columns, and the limiting columns are used to abut and limit the sealing baffle 31. It can be understood that the mechanical in-place reminder is realized by the abutment and limitation of the limiting column and the sealing baffle 31, which is convenient for manufacturing and simplifies the structure. Among them, each limiting column can be located at a position away from the central axis of the shielding portion 312. Alternatively, both the first limiting portion 13 and the second limiting portion 14 can be proximity switches. At this time, two trigger pieces arranged at circumferential intervals are also provided on the sealing baffle 31, and each trigger piece corresponds to a proximity switch. Or, one of the first limiting portion 13 and the second limiting portion 14 is a limiting column, and the other is a proximity switch. Only examples are given here.

[0066] Please refer to Figure 2 Exemplarily, based on the rotational assembly of the foregoing sealing baffle 31, a limiting baffle 111 is provided at one end of the fixed column 11 away from the bottom case 10; the sealing member 30 further includes an elastic member 32, and the elastic member 32 is arranged between the limiting baffle 111 and the sealing baffle 31, and the sealing baffle 31 has a movement tendency to press towards the bottom case 10 under the action of the elastic member 32. That is to say, the setting of the elastic member 32 is used to urge the sealing baffle 31 to always press towards the bottom case 10 to ensure the pressing degree between the sealing baffle 31 and the bottom case 10 at the first position; in particular, the elastic member 32 can be used to urge the sealing member 35 to closely fit between the shielding portion 312 of the sealing baffle 31 and the bottom case 10, improving the sealing effect.

[0067] In some specific embodiments, the sealing baffle 31, its corresponding seal 35 and the cover plate 36 are connected into an integral structure and installed in the assembly space 101 of the bottom case 10 to block the heat dissipation holes 102 from the inside of the bottom case 10. Such a setting can reduce the corrosiveness of the external medium to the sealing component 30, is not easily bumped, and prolongs the service life. At this time, the elastic member 32 is pressed between the sealing baffle 31 and the limiting baffle 111 to always apply a downward pressing force on the bottom case 10 to the sealing baffle 31. For example, the elastic member 32 is a compression spring.

[0068] Please refer to Figure 2 , Figure 5 , Figure 7 , Figure 8 and Figure 9 , and further, one of the bottom case 10 and the sealing baffle 31 is recessed with an avoidance groove 41, and the other is protruded with a top contact protrusion 42; in the first position, the top contact protrusion 42 is received in the avoidance groove 41, and the bottom case 10 and the sealing baffle 31 are in surface contact. In the second position, the top contact protrusion 42 moves out of the avoidance groove 41, and there is a gap between the bottom case 10 and the sealing baffle 31.

[0069] Specifically, a fitting boss 12 is protruded on one side of the bottom case 10 facing the assembly space 101. The end face of the fitting boss 12 is used as the first fitting surface, and the side wall of the shielding portion 312 of the sealing baffle 31 facing the bottom case 10 is used as the second fitting surface. The elastic member 32 is pressed between the limiting baffle 111 and the connecting portion 311. Taking the top contact protrusion 42 protruding from the second fitting surface of the sealing baffle 31 and the avoidance groove 41 being recessed in the first fitting surface of the bottom case 10 as an example.

[0070] When the shielding portion 312 needs to block the heat dissipation hole 102, the sealing baffle 31 rotates until the top contact protrusion 42 is received in the avoidance groove 41 to avoid interference; and, under the action of the elastic member 32, the shielding portion 312 urges the second fitting surface and the first fitting surface to be in surface contact, and the seal 35 is fully pressed between the shielding portion 312 and the bottom case 10 to ensure the sealing performance. When the blocking needs to be released, the sealing baffle 31 rotates until the top contact protrusion 42 moves out of the avoidance groove 41, and the top contact protrusion 42 presses against the first fitting surface so that there is a gap between the first fitting surface and the second fitting surface, that is, the surface contact between the first fitting surface and the second fitting surface is adjusted to point contact, thereby reducing the contact area between the sealing baffle 31 and the bottom case 10 and reducing wear.

[0071] In some specific embodiments, the avoidance groove 41 and the top contact protrusion 42 are in spherical cooperation. The spherical cooperation method is more conducive to the top contact protrusion 42 moving into and out of the avoidance groove 41, making the rotation operation of the sealing baffle 31 smoother and further reducing wear. At the same time, a plurality of top contact protrusions 42 are provided and arranged at intervals around the axis of the fixed column 11, and each top contact protrusion 42 is correspondingly provided with an avoidance groove 41. That is to say, the use of a plurality of top contact protrusions 42 in cooperation can form multi-point support during point contact, improve the support effect, and ensure balanced force.

[0072] Alternatively, it can also be that the top contact protrusion 42 protrudes from the first mating surface, and the avoidance groove is recessed in the second mating surface.

[0073] Such as Figure 1 and Figure 2 As shown, during actual use, the cooking appliance further includes a fastener (not shown in the figure), and the fastener passes through the fixed column 11 and is fixedly connected to the inner pot 20. Specifically, a connecting column 21 protrudes from the bottom of the inner pot 20, and the fixed column 11 is provided with a fixing hole 1101, and the fastener passes through the fixing hole 1101 and is threadedly connected to the connecting column 21. The setting of the fixed column 11 is not only used for cooperation with the sealing baffle 31, but also for the fixed assembly of the inner pot 20 relative to the bottom shell 10, realizing multi-purpose of one object and simplifying the structure.

[0074] Please refer to Figure 2 、 Figure 7 、 Figure 8 and Figure 9 Specifically, the mating boss 12 on the bottom shell 10 is arranged in a stepped shape, including a small-diameter section and a large-diameter section. The large-diameter section cooperates with the shielding portion 312 of the sealing baffle 31, and the small-diameter section cooperates with the connecting portion 311. The end of the fixed column 11 facing away from the inner pot is accommodated in the groove 1201 of the mating boss 12. The connecting portion 311 is provided with a first sleeving hole 3112 and a second sleeving hole 3113 that communicate with each other and are arranged in a stepped shape. The first sleeving hole 3112 cooperates with the small-diameter section of the mating boss 12, and the second sleeving hole 3113 is sleeved on the outside of the fixed column 11.
