Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, in particular to a cooking appliance. BACKGROUND

[0002] At present, most cooking appliances will generate steam during the cooking process. The steam flows upward and contacts the upper cover of the cooking appliance, and then condenses and generates condensed water. These condensed water not only falls on the food, affecting the taste of the food, but also condenses and drips onto the table surface when the cover is opened, causing unnecessary trouble.

[0003] In related technologies, a double-layer cover is used to form a heat preservation cavity, thereby improving the heat preservation effect of the pot cover itself and reducing the condensed water that directly falls onto the food or the table surface. However, since the outermost cover of the double-layer cover still contacts the external environment, the steam in the heat preservation cavity of the double-layer cover will still condense after contacting the outermost cover, resulting in a large amount of condensed water accumulating in the heat preservation cavity. If this condensed water cannot be discharged in time, it will corrode the pot cover itself over time and easily breed bacteria.

[0004] To this end, some double-layer covers use a detachable mode to assemble the two cover bodies, which facilitates the discharge of the accumulated water in the heat preservation cavity after disassembly. However, such an operation still has many inconveniences. For example, frequent disassembly leads to poor sealing between the two cover bodies, resulting in water leakage; and condensed water is easily leaked during the disassembly process. Practical new type content

[0005] Therefore, it is necessary to provide a cooking appliance that can facilitate the discharge of condensed water in the heat preservation cavity of the pot cover, reduce the amount of condensed water accumulated in the heat preservation cavity, and ensure good sealing of the heat preservation cavity after the pot cover is opened, thereby reducing the leakage of condensed water on the table surface and the like.

[0006] A cooking appliance includes a cooking base, a steaming rack arranged on the cooking base, and a pot cover arranged on the steaming rack. The steaming rack and the pot cover jointly define a cooking cavity. The pot cover includes an upper cover and a lower cover, which are connected and jointly surround a heat preservation cavity. The upper cover is provided with an air outlet hole communicating with the heat preservation cavity. The lower cover is provided with an air inlet hole communicating with the heat preservation cavity and the cooking cavity. One side of the lower cover protrudes with an extension table, which extends away from the upper cover and forms a water return chamber. The water return chamber communicates with the heat preservation cavity, and the bottom wall of the water return chamber is provided with a water outlet hole. The cooking appliance further includes a sealing assembly, which includes a sealing piece and a top contact piece. The sealing piece is located in the water return chamber and is used to block the water outlet hole. The top contact piece is configured to drive the sealing piece away from the water outlet hole in response to an external force.

[0007] It can be understood that the setting of the backwater tank is beneficial to the condensate generated due to the lower temperature of the upper cover, reduces the amount of condensate accumulated in the heat preservation cavity, and the cooperation of the sealing element and the top contact element in the sealing assembly meets the plugging and opening adjustment of the water outlet hole, thereby realizing the discharge of the condensate in the backwater tank. When it is necessary to discharge the condensate, the top contact element can be driven to drive the sealing element away from the water outlet hole to open the water outlet hole, and the condensate in the backwater tank flows out of the water outlet hole; when there is no need to discharge water, the sealing element plugs the water outlet hole to ensure that the condensate in the backwater tank does not flow out. Such a setting is convenient for adjusting the opening and plugging of the water outlet hole according to the use requirements, not only facilitates the discharge of the condensate in the heat preservation cavity, but also ensures that the condensate does not leak after the cover is opened; and in the whole water discharge process, the condensate in the heat preservation cavity can be discharged without disassembling the upper cover and the lower cover, the operation is more convenient, and the problem of condensate leakage in the disassembly process and the problem of water leakage caused by frequent disassembly are thus alleviated.

[0008] In some embodiments, the extension platform is arranged at or near the side of the heat preservation cavity, and the top surface of the lower cover is arched and includes a flow guide surface inclined toward the backwater tank.

[0009] Such a setting, on the one hand, reduces the influence of the extension platform setting on the placement and cooking of food; on the other hand, it can ensure that the backwater tank is located as far away from the food as possible when the cover is in use, reducing the condensate from the backwater tank falling onto the food during cooking. At the same time, the flow guide surface is beneficial to guiding the condensate to flow to the backwater tank.

[0010] In some embodiments, the top surface of the lower cover is circumferentially arranged with an upwardly extending limiting stop rib, and the lower cover is provided with a flow-through hole communicating the heat preservation cavity and the backwater tank, and the flow-through hole is located on the inner side of the limiting stop rib.

[0011] In this way, a water storage tank for temporarily storing condensate is formed at the edge of the lower cover, so as to avoid leakage of condensate from the gap between the lower cover and the upper cover as much as possible.

[0012] In some embodiments, the sealing element and the top contact element are separately arranged, the sealing element is arranged in the backwater tank, and the top contact element is arranged outside the backwater tank, and part of the top contact element can penetrate into the water outlet hole to push the sealing element.

[0013] Such a setting ensures that the sealing element can only drive the top contact element to push the sealing element to open the water outlet hole when the cover is in use, and the sealing element can be pressed on the water outlet hole to achieve plugging under the action of its own gravity after the cover is removed, thereby reducing the condensate leaking to the table.

[0014] In some embodiments, the top contact is arranged on the steamer; the pot cover is arranged on the steamer, and the top contact can penetrate into the water outlet hole to push the sealing element.

[0015] In some embodiments, the sealing element and the top contact are arranged integrally, the sealing element is arranged on the water return chamber, the top contact is arranged penetratingly in the water outlet hole and partially protrudes from the bottom of the extension table, and the top contact can move along the axial direction of the water outlet hole under the action of external force to push the sealing element.

[0016] Such an arrangement can integrate the sealing assembly on the pot cover, and thus no special structural improvement is needed for the cooking base or the steamer, as long as the pot cover can abut and push the top contact to move when the pot cover is arranged, thereby driving the sealing element.

[0017] In some embodiments, the bottom of the top contact is provided with a limiting end face, which can abut the bottom of the extension table to constrain the pushing distance of the sealing element, facilitating secondary sealing.

[0018] In some embodiments, the water outlet hole is arranged tapering along the water outlet direction. Such an arrangement can guide the sealing element while ensuring sealing cooperation with the sealing element, facilitating accurate positioning of the sealing element relative to the water outlet hole for sealing.

[0019] In some embodiments, the upper cover is provided with a surrounding part, which surrounds the outer side of the extension table, and the bottom of the extension table does not protrude from the bottom of the surrounding part, thereby reducing the interference with the arrangement of the pot cover.

[0020] In some embodiments, the water return chamber is further provided with a flange surrounding the outer circumferential side of the water outlet hole, the flange surrounds to form an assembly space connecting the water return chamber and the water outlet hole, and the sealing element is movably arranged in the assembly space.

[0021] That is, the assembly space surrounded by the flange can constrain the assembly of the sealing element, avoiding the failure of the sealing element to fall back to the water outlet hole.

[0022] In some embodiments, the top end of the flange is provided with a limiting part, which gradually decreases in cross section from bottom to top.

[0023] That is, when the top contact pushes the sealing element to move upward to release the sealing of the water outlet hole, the arrangement of the limiting part can avoid the complete separation of the top contact and the secondary sealing.

[0024] In some embodiments, the edge of the steaming rack is provided with a water collecting groove and a water leakage hole formed in the bottom wall of the water collecting groove, and the top contact piece is arranged at the edge of the water collecting groove or close to the water collecting groove. In this way, the condensed water flowing out of the water outlet hole can flow to the water collecting groove on the steaming rack as much as possible, and then drip to the cooking base from the plurality of water leakage holes, reducing the condensed water flowing to the food materials.

The terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. All publications, patent applications, patents, and other references mentioned in the specification are incorporated by reference in their entirety.

[0042] Please refer to Figure 1 and Figure 5 , the present application provides a cooking appliance, which facilitates the discharge of condensed water in the heat preservation cavity 201 of the pot cover 20, thereby reducing the amount of condensed water remaining in the heat preservation cavity 201 and alleviating the leakage problem caused by the accumulation of condensed water in the heat preservation cavity 201 after the cover is opened. The cooking appliance will be described in detail below.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , for example, the cooking appliance includes a cooking base 10, a steaming rack 40 arranged on the cooking base 10, and a pot cover 20 arranged on the steaming rack 40, and the steaming rack 40 and the pot cover 20 jointly define a cooking cavity 101. The pot cover 20 includes an upper cover 21 and a lower cover 22, which are connected and jointly enclosed to form a heat preservation cavity 201. The upper cover 21 is provided with a gas outlet hole 207 communicating with the heat preservation cavity 201, and the lower cover 22 is provided with a gas inlet hole 206 communicating with the heat preservation cavity 201 and the cooking cavity 101. The steam in the cooking cavity 101 flows into the heat preservation cavity 201 from the gas inlet hole 206 and fills the heat preservation cavity 201 to provide a heat preservation effect for the lower cover 22, and the excess steam flows out from the gas outlet hole 207 to maintain the pressure balance of the heat preservation cavity 201. Such a design is equivalent to adding an air heat preservation layer to the upper surface of the upper cover 21, reducing the temperature difference between the lower cover 22 and the cooking cavity 101, and alleviating the condensation problem caused by the contact between the steam in the cooking cavity 101 and the lower surface of the upper cover 21.

[0044] However, since the upper cover is still in contact with the external environment, it will be affected by the low temperature from the external environment, causing the steam in the heat preservation cavity to condense when it contacts the lower surface of the upper cover, and the condensed water produced will accumulate in the heat preservation cavity. If this condensed water cannot be discharged in time, it will cause corrosion to the pot cover itself over a long period of time, and bacteria will easily breed. Although the upper cover and the lower cover can be easily disassembled by a detachable assembly method to discharge the accumulated water in the heat preservation cavity. However, considering the sealing performance when the upper cover and the lower cover are connected, they are usually assembled in a more secure manner, which requires a large force to be exerted every time they are disassembled, making the operation extremely inconvenient and increasing the cleaning process and difficulty; and if they are disassembled frequently, it will inevitably cause wear and tear at the connection between the two, thereby affecting the firmness and sealing performance of the connection between the two, and water leakage will easily occur. In addition, the condensed water will easily leak during the disassembly process, causing unnecessary trouble or health hazards.

[0045] For this purpose, please refer to Figures 1 to 6 The cooking utensil provided by the embodiment comprises an upper cover 21 and a lower cover 22, and the lower cover 22 is provided with a heat preservation cavity 201. The upper cover 21 is connected to the lower cover 22, and the heat preservation cavity 201 is formed between the upper cover 21 and the lower cover 22. The upper cover 21 is provided with a steam outlet 202, and the steam outlet 202 is connected to the heat preservation cavity 201. The lower cover 22 is provided with a water outlet 203, and the water outlet 203 is connected to the heat preservation cavity 201. The water outlet 203 is arranged on the bottom wall of the heat preservation cavity 201.

[0046] When the steam condenses on the lower surface of the upper cover 21 due to the temperature difference, the condensed water produced can flow from the heat preservation cavity 201 into the water return chamber 202, reducing the amount of condensed water accumulated in the heat preservation cavity 201. Moreover, by arranging the sealing member 31 and the top contact member 32, the sealing and opening of the water outlet 203 can be adjusted. Therefore, when the condensed water needs to be discharged, the top contact member 32 drives the sealing member 31 away from the water outlet 203 to open, and the condensed water in the water return chamber 202 flows out from the water outlet 203; when there is no need to discharge water, the sealing member 31 seals the water outlet 203 to ensure the sealing performance and reduce the leakage amount.

[0047] The sealing member 31 is movably arranged in the backwater bin 202, and is beneficial to open and close the water outlet hole 203 under the action of the top contact piece 32. Of course, the sealing member 31 can also move under the action of its own gravity to block the water outlet hole 203. For example, the sealing member 31 can be rotationally connected to the bin wall of the backwater bin 202, and the top contact piece 32 can push the sealing member 31 to rotate to open the water outlet hole 203. When the top contact piece 32 and the sealing member 31 are relatively far away, the sealing member 31 reversely rotates under the action of its own gravity to block the water outlet hole 203. Of course, a restoring member can also be installed between the sealing member 31 and the bin wall of the backwater bin 202, so that the sealing member 31 can be driven to move reversely to block the water outlet hole 203 when the sealing member 31 is not subjected to the force of the top contact piece 32. Alternatively, the sealing member 31 is pressed on the side edge of the water outlet hole 203 facing the backwater bin 202 only by its own gravity. At this time, the size of the sealing member 31 is smaller than the size of the backwater bin 202 and larger than the size of the water outlet hole 203. This is only an example.

[0048] That is, the cooking utensil provided by the present application utilizes the arrangement of the backwater bin 202 to play a role in gathering the condensed water in the heat preservation cavity 201; and in combination with the adjustment of the sealing assembly 30, the opening and blocking of the water outlet can be adjusted according to the use requirements. In this way, not only the amount of condensed water gathered in the heat preservation cavity 201 is reduced, but also the risk of water leakage after the cover is opened is reduced. At the same time, during the entire drainage process, the condensed water can be discharged without the need to disassemble the upper cover 21 and the lower cover 22, thereby reducing the cleaning process and difficulty; and since the drainage operation does not depend on the frequent disassembly between the upper cover 21 and the lower cover 22, the problems of condensed water leakage in the disassembly process and water leakage caused by wear and tear due to frequent disassembly are alleviated.

[0049] The lower cover 22 is provided with a flow-through hole 204, and the heat preservation cavity 201 is communicated with the backwater bin 202 through the flow-through hole 204, which is beneficial to the flow of the condensed water to the backwater bin 202.

[0050] Please continue to refer to Figures 1 to 5 Further, the extension table 23 is arranged at or near the side of the heat preservation cavity 201, that is, the backwater bin 202 is located at or near the side of the heat preservation cavity 201. Such an arrangement, on the one hand, reduces the influence of the arrangement of the extension table 23 on the placement and cooking of food materials; on the other hand, it can ensure that the backwater bin 202 is located as far away from the food materials as possible when the pot cover 20 is in use, thereby reducing the condensed water dripping from the backwater bin 202 to the food materials during the cooking process.

[0051] Furthermore, the top surface of the lower cover 22 (i.e., the side of the lower cover 22 facing closer to the upper cover 21) can be arched and include a guide surface 205 inclined towards the return water tank 202, which facilitates the flow of condensate water to the return water tank 202. In other words, the guide surface 205 is inclined from top to bottom towards the flow hole 204, and the condensate water generated on the side wall of the upper cover 21 facing the insulation cavity 201 can be guided along the guide surface 205 to the flow hole 204 and fall into the return water tank 202 under its own gravity.

[0052] Alternatively, the upper cover 21 may arch towards the side away from the lower cover 22 (i.e., the lower surface of the upper cover 21) to form a guide surface. Or, both the upper cover 21 and the lower cover 22 may arch upwards to respectively provide corresponding guide surfaces. In this case, the condensate on the lower surface of the upper cover 21 can flow along the guide surface of the upper cover 21 towards the side and drip onto the top surface of the lower cover 22, flowing along the guide surface 205 of the lower cover 22 towards the side, thus converging as fully as possible at the flow hole 204 to flow into the return water tank 202. This is only required to ensure that the condensate on the upper surface of the upper cover 21 is guided to the flow hole 204 via the guide surface 205 and falls into the return water tank 202 under its own weight. This is merely an example.

[0053] like Figures 1 to 5 As shown, furthermore, the top surface of the lower cover 22 is provided with an upwardly extending limiting rib 221 along the circumferential direction, and the aforementioned flow hole 204 is located inside the limiting rib 221. This effectively forms a water storage tank for temporarily storing condensate at the edge of the lower cover 22, minimizing leakage of condensate from the gap between the lower cover 22 and the upper cover 21. The lower cover 22 has a straight section 223 near the limiting rib 221, located at the lowest point of the guide surface 205 on the lower cover 22. The straight section 223 buffers the flow of condensate, mitigating the impact of the limiting rib 221 on the condensate left through the guide surface 205, reducing splashing, and thus alleviating the problem of condensate leakage from the gap between the upper cover 21 and the lower cover 22.

[0054] In some embodiments, when the cross-section of the cooking base 10 is square or near-square, the shape of the steaming rack 40 and the shape of the lid 20 are adapted to match it. In this case, an extension platform 23 is provided on one side of the lower cover 22, and the cross-section of the extension platform 23 is rectangular, which facilitates the collection of more condensate. Alternatively, extension platforms 23 are provided on two opposite sides of the lower cover 22; or, each side is provided with an extension platform 23. The only requirement is that the extension platform 23 is located at the lowest point of the lower cover 22 in the vertical direction to facilitate the collection of condensate. This is merely an example.

[0055] Of course, the cross section of the cooking base 10 can also be circular or quasi-circular, and the cross section of the extension table 23 is correspondingly arc-shaped.

[0056] The shape of the flow-through hole 204 is matched with the cross-sectional shape of the extension table 23, and sufficient space is ensured for the condensed water in the heat preservation cavity 201 to flow to the water return bin 202.

[0057] In some embodiments, the bottom wall of the water return bin 202 can be provided with a water outlet hole 203, and the water outlet hole 203 is located at or near the middle of the length direction of the cross section of the extension table 23. The bottom wall of the water return bin 202 can be inclined downward from top to bottom towards the water outlet hole 203, so as to guide the condensed water to converge towards the water outlet hole 203. Of course, the water outlet hole 203 can also be provided with at least two, and arranged at intervals along the length direction of the cross section of the extension table 23. Each water outlet hole 203 corresponds to a set of sealing assemblies 30, so as to improve the water outlet efficiency. For example, the number of water outlet holes 203 is two, three, four, etc.

[0058] It should be noted that the number of water outlet holes 203 should not be too much, otherwise the strength of the bottom of the extension table 23 will be weakened.

[0059] In some embodiments, the top contact 32 and the sealing member 31 are separately arranged. The sealing member 31 is located in the water return bin 202 and used to block the water outlet hole 203, and the top contact 32 is arranged outside the water return bin 202. Part of the top contact 32 can penetrate into the water outlet hole 203 to push the sealing member 31. For example, the top contact 32 is arranged at the pot opening of the cooking base 10. When the pot cover 20 is arranged on the steaming rack 40, part of the top contact 32 extends into the water outlet hole 203 to push up the sealing member 31, so as to open the water outlet hole 203. Since the water return bin 202 is arranged at the side of the heat preservation cavity 201, it is equivalent to draining along the side of the cooking base 10. At the same time, since the top contact 32 and the sealing member 31 are separately arranged, only when the pot cover 20 is arranged during cooking, the top contact 32 can push the sealing member 31. When the pot cover 20 is removed, the sealing member 31 can be pressed on the water outlet hole 203 under the action of its own gravity to block the water outlet hole 203, so as to reduce the leakage of condensed water to the table top. Since the water outlet hole 203 is in an open state during cooking, the condensed water in the heat preservation cavity 201 can continuously flow into the cooking base 10 through the water outlet hole 203 of the water return bin 202, so as to reduce the amount of condensed water accumulated in the heat preservation cavity 201 and the water return bin 202, and also reduce the amount of leakage after opening the cover.

[0060] Please continue to refer to Figure 1 , Figure 2 , Figure 6 and Figure 7Further, the backwater chamber 202 is further provided with a flange 231 arranged around the outer circumferential side of the water outlet hole 203. The flange 231 surrounds to form an assembly space 2301 which communicates the backwater chamber 202 and the water outlet hole 203, and the sealing member is movably arranged in the assembly space 2301. It can be understood that the assembly space 2301 surrounded by the flange 231 plays a restraining role in the assembly of the sealing member 31, avoiding the sealing member 31 from not falling back to the water outlet hole 203. The size of the assembly space 2301 surrounded by the flange 231 is greater than the size of the sealing member 31 itself. Specifically, the size of the assembly space 2301 along the axial direction of the water outlet hole 203 is greater than the size of the sealing member 31 along the axial direction of the water outlet hole 203, and the cross section of the assembly space 2301 is greater than the cross section of the sealing member 31, so as to ensure the movement allowance of the sealing member 31 along the axial direction and the radial direction of the water outlet hole 203 in the assembly space 2301. In this way, the assembly of the sealing member 31 is effectively restrained, and sufficient space is maintained for the flow of condensed water.

[0061] Of course, the cross section of the assembly space 2301 should not be too large, otherwise the limiting effect will be weakened, causing the sealing member 31 to deviate to a position away from the water outlet hole 203, which is not conducive to secondary sealing. The size of the assembly space 2301 along the axial direction of the water outlet hole 203 should not be too small, otherwise the sealing member 31 may block the assembly space 2301 or move out of the assembly space 2301 under the action of the top pushing piece 32, which is not conducive to the flow of condensed water and is not conducive to secondary sealing.

[0062] Optionally, the top end of the flange 231 is provided with a limiting portion 232, which gradually decreases from bottom to top in cross section, for limiting the movement of the sealing member 31 in the pushing direction. That is, the limiting portion 232 limits the upward movement range of the sealing member 31, so as to ensure that the sealing member 31 will not deviate to a position away from the water outlet hole 203 after being pushed, and to ensure that the sealing member 31 can reseal at the water outlet hole 203 after the action of the top pushing piece 32 is removed. When the pot cover 20 is arranged on the steaming rack 40, the top pushing piece 32 pushes the sealing member 31 to move upward to release the sealing of the water outlet hole 203, and at this time the setting of the limiting portion 232 can avoid the complete separation of the top pushing piece 32 and the secondary sealing.

[0063] Of course, the end of the flange 231 away from the water outlet hole 203 can also be provided with a blocking arm along the radial direction of the water outlet hole 203, so as to realize the restraint of the sealing member 31 as the limiting portion 232.

[0064] Please continue to refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8As some of the embodiments, the top touch 32 is arranged on the steamer 40. When the pot cover 20 is arranged on the steamer 40, the top touch 32 can penetrate into the water outlet hole 203 to push the sealing member 31 upwards to open the water outlet hole 203.

[0065] Further, the top touch 32 comprises a top touch portion 321 and an assembly portion 322 connected to the top touch portion 321. The assembly portion 322 can be integrally formed on the steamer 40, and of course the assembly portion 322 can be welded or bonded or fastened to the steamer 40 by screws. The diameter of the top touch portion 321 is smaller than the diameter of the assembly portion 322, so as to penetrate into the water outlet hole 203 to push the sealing member 31. The end face of the assembly portion 322 towards the top touch portion 321 can be used as a limiting end face 3201 for abutting against the bottom of the extension table 23, thereby restricting the pushing distance of the sealing member 31 and facilitating secondary plugging. The height of the top touch portion 321 in the top touch 32 is between 1mm-5mm, for example, 1mm, 1.8mm, 2.5mm, 3mm, 4mm, 4.5mm or 5mm. Optionally, the height of the top touch portion 321 is 2mm. As long as it can push the sealing member 31 to open the water outlet hole 203.

[0066] In some specific embodiments, the water return bin 202 is arranged corresponding to the edge of the steamer 40. The edge of the steamer 40 is provided with a water collecting groove 401 and a water leakage hole 402 arranged on the bottom wall of the water collecting groove 401. The top touch 32 is arranged at the edge of the water collecting groove 401 or near the water collecting groove 401, so that the condensed water flowing out of the water outlet hole 203 can flow to the water collecting groove 401 on the steamer 40 as much as possible, and then drip from the water leakage hole 402 to the cooking base 10. The water leakage hole 402 can also be provided with a plurality of water leakage holes, which are arranged at intervals, for example, along the length direction of the water collecting groove 401. The condensed water flowing out of the water outlet hole 203 can also flow to the water collecting groove 401 through the limiting end face 3201 and the side wall of the assembly portion 322. The limiting end face 3201 can be arranged downwardly inclined from the middle to the edge, which plays a role of water guide. Of course, the water collecting groove 401 is arranged at a lower position of the steamer 40, or the food placement area of the steamer 40 is slightly higher than the groove of the water collecting groove 401. At this time, even if part of the condensed water flows towards the food placement area, it will flow to the water collecting groove 401 under the action of the self-guiding structure of the steamer 40.

[0067] As some of the embodiments, the top touch 32 is arranged on the steamer 40. When the pot cover 20 is arranged on the steamer 40, the top touch 32 can penetrate into the water outlet hole 203 to push the sealing member 31 upwards to open the water outlet hole 203. Figure 1 , Figure 5 , Figure 9 and Figure 10In other embodiments, the sealing member 31 and the top pushing member 32 are integrated, i.e. the sealing member 31 and the top pushing member 32 are connected as a whole. In this case, the sealing member 31 is still located in the water return chamber 202, and the top pushing member 32 is arranged in the water outlet hole 203 and partially protrudes from the bottom of the extension platform 23. The top pushing member 32 is axially movable along the water outlet hole 203 under the action of an external force to push the sealing member 31. When the pot cover 20 is arranged on the cooking base 10 or the steaming rack 40, the bottom of the top pushing member 32 can abut against the cooking base 10 or the steaming rack 40, and then moves upward along with the arrangement of the pot cover, and drives the sealing member 31 to move to unblock the water outlet hole 203.

[0068] It can be understood that, by integrating the sealing member 31 and the top pushing member 32, the sealing assembly 30 can be integrated and assembled on the pot cover 20, and thus it is not necessary to specially improve the structure of the cooking base 10 or the steaming rack 40, as long as the top pushing member 32 can be abutted and pushed to move when the pot cover 20 is arranged, and then the sealing member 31 is driven.

[0069] Specifically, the top pushing part 321 of the top pushing member 32 is connected with the sealing member 31, and the assembly part 322 of the top pushing member 32 is located outside the water return chamber 202 and is used to abut against the cooking base 10 or the steaming rack 40. The limiting end face 3201 on the assembly part 322 is used to limit the movement distance of the top pushing member 32, and then limit the lifting distance of the sealing member 31.

[0070] Please refer to Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 9 and Figure 10 , for example, the water outlet hole 203 is tapered along the water outlet direction, i.e. the cross section gradually decreases from top to bottom. The water outlet direction is the direction of the condensed water flowing out of the water outlet hole 203. Such arrangement not only ensures the cooperation and sealing with the sealing member 31, but also guides the sealing member 31 to accurately position relative to the water outlet hole 203 for blocking. In addition, the tapered arrangement also limits the sealing member 31, and reduces the offset amount of the sealing member 31 when it is opened. The diameter of the top pushing part 321 of the top pushing member 32 is smaller than the minimum diameter of the water outlet hole 203. In this way, it is not only beneficial to the extension of the top pushing part 321 into the water outlet hole 203 to push the sealing member 31, but also ensures that there is sufficient space between the outer wall of the top pushing part 321 and the hole wall of the water outlet hole 203 for the condensed water to flow.

[0071] Further, the sealing member 31 is in the form of a ball. The ball is configured to facilitate cooperation with the tapered water outlet hole 203, increase the sealing area, and improve the sealing effect. In addition, the ball is configured to facilitate unsealing. As long as the sealing position of the ball relative to the water outlet hole 203 is raised to a position greater than the diameter of the ball on the horizontal plane, the sealing can be released, and the condensed water can be discharged. The diameter of the sealing member 31 is between 1 mm and 30 mm, for example, 1 mm, 8 mm, 10 mm, 20 mm, 25 mm, or 30 mm. In some specific embodiments, the diameter of the sealing member 31 is 10 mm.

[0072] Alternatively, the sealing member 31 can also be in the form of a plate or a hemisphere or a curved plate, as long as it can seal the water outlet hole 203 and cooperate with the top contact 32 to release the sealing.

[0073] In some specific embodiments, the water outlet hole 203 is further provided with a cylindrical section at the maximum hole diameter, and the diameter of the sealing member 31 is substantially the same as the diameter of the cylindrical section. In this way, part of the sealing member 31 can be pressed on the cylindrical section, and the lower part can be pressed on the tapered part to form a double seal and improve the sealing effect.

[0074] Please continue to refer to Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 9 and Figure 10 In some embodiments, the upper cover 21 is provided with a surrounding portion 24, which surrounds the outer side of the extension platform 23. The surrounding portion 24 is configured to cooperate with the cooking base 10 or the steaming rack 40 to achieve the clamping cooperation of the pot cover 20 relative to the cooking base 10 or the steaming rack 40. The edge of the surrounding portion 24 is provided with a lapping edge 241, which is configured to be lapped on the edge of the cooking base 10 or the steaming rack 40. For example, the steaming rack 40 is lapped on the pot opening edge of the cooking base 10, and the lapping edge 241 is lapped on the edge of the steaming rack 40.

[0075] In this way, the bottom of the extension platform 23 is not protruded from the bottom of the surrounding portion 24, which reduces the interference with the pot cover 20. In addition, when the sealing member 31 and the top contact 32 are in an integral structure, the sealing member 31 can be ensured to be in a sealing state when the pot cover 20 is placed on the platform.

[0076] As Figure 1 and Figure 5As shown, the enclosure 24 is provided with a support table 25, and the lower cover 22 is overlapped on the support table 25 to support the lower cover 22 and assemble the lower cover 22 and the upper cover 21. When the lower cover 22 is supported on the support table 25, the top of the limiting stop rib 221 on the lower cover 22 has an assembly gap with the lower surface of the upper cover 21, so that the lower cover 22 has a certain assembly allowance relative to the upper cover 21, which facilitates the disassembly of the lower cover 22. The support table 25 is provided with at least two and is arranged in a circumferential direction of the upper cover 21. In addition, the upper cover 21 and the lower cover 22 can also be provided with a structure for achieving clamping cooperation to improve the reliability of the connection of the lower cover 22 relative to the upper cover 21. For example, the lower cover 22 and the upper cover 21 are fastened by using the clamping cooperation of the clamping groove and the clamping arm. The cross section of the support table 25 in the vertical direction is triangular to reduce interference.
