Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to cooking equipment. Background Art

[0002] Currently, most cooking devices on the market, such as rice cookers and pressure cookers, have a single inner pot that can only cook a single ingredient. This fails to meet user demands for multiple textures for the same food or for cooking multiple ingredients simultaneously. Therefore, those skilled in the art have developed dual-pot cooking devices that can serve two purposes in one pot. However, existing dual-pot cooking devices require both pots to be used simultaneously for proper assembly, limiting their use cases. Summary of the Invention

[0003] In view of this, the present invention provides a cooking device to solve the problem of limited usage scenarios of double-pot cooking devices in the prior art.

[0004] The present invention provides a cooking device, comprising a pot body, the pot body comprising: Support members; A first inner pot is detachably disposed in the support member, and the first inner pot has a first pot edge that can overlap the support member; The second inner pot is detachably arranged in the first inner pot, and the second inner pot has a second pot edge, which can be overlapped on the first pot edge or the support member; The cooking device has a double-pot usage state in which the first pot is overlapped in the support member and the second pot is overlapped in the first pot, and a single-pot usage state in which either the first pot or the second pot is overlapped in the support member. Beneficial effect: the first inner pot is detachably arranged in the support, and the second inner pot is detachably arranged in the first inner pot, which is convenient for taking out the first inner pot and the second inner pot, and the pot edge of the second inner pot can be overlapped on the pot edge of the first inner pot or the support, so that the two inner pots can not only be installed at the same time for zoned cooking, but also when the user needs a large-capacity inner pot for cooking, the first inner pot can be placed on the support alone for use, and when the user needs a small-capacity inner pot for cooking, the second inner pot can be placed on the support alone for use, so that the user can install the two inner pots at the same time for use, and can install and use each inner pot independently according to actual needs, making the application scenarios of the cooking equipment more diversified, increasing the usage scenarios of the cooking equipment, improving the user experience, and effectively solving the problem that the two inner pots of the existing double-pot cooking equipment must be used at the same time and the user usage scenarios are relatively limited.

[0005] In an optional embodiment, the support member includes a support ring, and the outer diameters of the first pot edge and the second pot edge are both larger than the diameter of the support ring.

[0006] Beneficial effect: By adopting a design in which the outer diameters of the first pot edge and the second pot edge are both larger than the diameter of the support ring, the first inner pot and the second inner pot can not only be used at the same time, but also ensure that the two inner pots can be independently installed on the support ring for separate use, thereby realizing a universal design of single and double inner pot installation structures, effectively solving the problem that existing double-pot cooking equipment can only use two inner pots at the same time, or only the outer inner pot can be used alone and the inner inner pot cannot be used alone.

[0007] In an optional embodiment, the outer diameter of the second pot rim is greater than the outer diameter of the first pot rim.

[0008] Beneficial effect: By setting the outer diameter of the second pot edge to be larger than the outer diameter of the first pot edge, not only can the sealing of the second inner pot and the reliability and stability of the installation of the first inner pot and the second inner pot be ensured when the two inner pots are used at the same time, but it is also more convenient for the user to take the first inner pot out of the second inner pot.

[0009] In an optional embodiment, a vent hole is provided on the second pot edge; When the cooking device is in a double-pot use state, the vent hole is communicated with the interior of the first inner pot.

[0010] Beneficial effect: The vent holes provided on the second pot edge allow the steam inside the first inner pot to be discharged normally, effectively ensuring the air pressure balance in the two inner pots during double-pot cooking and preventing food from overflowing.

[0011] In an optional embodiment, a supporting flange is provided on the outer peripheral side of the first pot edge, and the supporting flange is used to support the second pot edge; A first sealing structure is provided on the supporting flange, and the first sealing structure is used to seal the fitting gap between the first pot edge and the second pot edge. Beneficial effect: When two inner pots are used at the same time, the rim of the first inner pot is directly placed on the support ring, and the second inner pot is placed in the middle of the first inner pot. Different foods can be cooked in different areas. The rim of the second inner pot can be supported by the support flange arranged on the outer peripheral side of the rim of the first inner pot, and the first sealing structure arranged on the support flange can seal the first pot rim and the second pot rim to prevent steam leakage from the side, thereby ensuring the cooking effect.

[0012] In an optional embodiment, the cooking device further comprises: The pot cover has a closed state that closes the pot body and an open state that opens the pot body; The lid includes: The heat-insulating cover assembly is located on the side of the pot lid close to the pot body, and is provided with an exhaust hole; When the cooking device is in double pot use state and the pot cover is in the closed state, there is a gap between the heat preservation cover assembly and the second pot edge, and the gap forms a steam discharge channel connecting the vent hole and the exhaust hole on the second pot edge.

[0013] Beneficial Effects: The heat-insulating cover plate installed above the inner pot can seal the pot mouth, preventing large amounts of water loss during cooking. Furthermore, the vent holes provided on the heat-insulating cover plate assembly allow water vapor generated during cooking to be discharged through the vent holes of the heat-insulating cover plate assembly and the air outlet on the upper cover of the pot lid. Furthermore, a steam discharge channel is formed between the heat-insulating cover plate and the second pot edge. When two inner pots are used simultaneously, steam inside the first inner pot can be discharged through the vent holes on the second pot edge and the steam discharge channel. This allows the steam inside the first inner pot to be discharged normally, effectively ensuring air pressure balance in the two inner pots during dual-pot cooking and preventing food from heating and overflowing.

[0014] In an optional embodiment, the thermal insulation cover assembly further includes: Insulation cover; The second sealing structure is installed on the thermal insulation cover plate and is used to seal the first inner liner or the second inner liner.

[0015] Beneficial effect: By setting the second sealing structure on the insulation cover, the pot edge of the first inner pot or the second inner pot can be sealed, effectively ensuring the sealing and reliability of the first inner pot or the second inner pot, and ensuring the air pressure balance in the two inner pots during cooking.

[0016] In an optional embodiment, the second sealing structure is an annular seal; When the cooking device is in a double pot use state and the pot lid is in a closed state, the second sealing structure presses against the top surface of the second pot edge, and the vent hole is located on the inner circumference of the second sealing structure; When the cooking device is in a single pot use state and the pot cover is in a closed state, the second sealing structure is pressed against the top surface of the first pot edge or the second pot edge. Beneficial Effects: By positioning the vent holes on the second pot rim inside the second sealing structure, steam leakage from the pot rim's sides can be effectively prevented, while ensuring that steam within the first pot can be smoothly discharged through the vent holes and steam discharge channel. Furthermore, regardless of whether the cooking device is in dual-pot mode or single-pot mode, the second sealing structure can press against the top surface of either the first or second pot rim, effectively ensuring sealing and reliability when both pots are used simultaneously or when either pot is used alone.

[0017] In an optional embodiment, the second sealing structure includes: The elastic sealing portion has a compressed state and an uncompressed state, and the bottom of the elastic sealing portion has an annular sealing surface suitable for abutting against the top surface of the first pot edge or the second pot edge; When the pot lid is in the closed state, the elastic sealing portion is compressed and abuts against the top surface of the first pot edge or the second pot edge, and the fitting width between the annular sealing surface and the first pot edge or the second pot edge is not less than 3 mm.

[0018] Beneficial effect: By setting the overlapping width of the second sealing structure with the first pot edge and the second pot edge in the horizontal direction to be no less than 3 mm, the reliability of the circumferential sealing of the first inner liner and the second inner liner can be effectively ensured.

[0019] In an optional embodiment, the vertical distance between the annular sealing surface of the elastic sealing portion in an uncompressed state and the bottom surface of the thermal insulation cover is set to d1; When the first inner pot is overlapped in the support member, the vertical distance between the top surface of the first pot edge and the bottom surface of the insulation cover plate is set to d2, where d1-d2≥1mm; When the second inner pot is overlapped in the support member, the vertical distance between the top surface of the second pot edge and the bottom surface of the thermal insulation cover is set to d3, wherein d1-d3≥1mm.

[0020] Beneficial effect: By adopting the above-mentioned size design, whether cooking with two inner pots at the same time or using either inner pot alone, it can be ensured that the annular sealing surface of the elastic sealing part can fit against the first pot edge or the second pot edge, thereby ensuring the sealing reliability of the first inner pot and the second inner pot in the axial direction.

[0021] In an optional embodiment, the thermal insulation cover assembly further includes: a cover plate bracket, arranged on the outer peripheral side of the thermal insulation cover plate, for mounting and fixing the thermal insulation cover plate and the second sealing structure; The second sealing structure includes: a mounting portion, the mounting portion being clamped onto the cover bracket, the thermal insulation cover comprising a cover body and an annular pressing edge provided on the outer periphery of the cover body, the annular pressing edge pressing the mounting portion tightly onto the cover bracket; The cover plate bracket is provided with a clamping hole, and the outer periphery of the annular pressing edge is provided with a cover plate clamping claw. The cover plate clamping claw is inserted into the clamping hole, and the end portion is bent inwardly and tightly clamped on the cover plate bracket.

[0022] Beneficial Effects: The cover plate body is a flat plate structure, and the annular pressure edge is formed by extending the outer peripheral wall of the cover plate body upward by a set length and then extending toward the outer peripheral side. The annular pressure edge presses the mounting portion of the second sealing structure against the cover plate bracket, preventing the second sealing structure from falling off. By providing a cover plate clamping claw, inserting the cover plate clamping claw into the clamping hole, and bending the end of the cover plate clamping claw inward and clamping it against the cover plate bracket, the second sealing structure is pressed between the thermal insulation cover plate and the cover plate bracket, achieving effective fixation of the thermal insulation cover plate, the second sealing structure, and the cover plate bracket, ensuring the stability of the three, and further reducing the risk of the second sealing structure falling off or shifting.

[0023] In an optional embodiment, the cooking device is an electric rice cooker or a pressure cooker. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] The related art double-pot cooking device includes a first inner pot and a second inner pot disposed inside the first inner pot. Although it can achieve zoned cooking and meet the user's needs for multiple tastes of the same food or cooking multiple ingredients at the same time, it does not fully consider the problems that may exist in actual cooking, such as: 1. When two inner pots are used at the same time, the usable space of the two pots will inevitably be compressed, which is smaller than the space when the first inner pot is used alone, resulting in a smaller cooking capacity. In addition, the existing cooking equipment with a dual-pot design does not take into account the universal assembly structure when each pot is used independently, resulting in the two pots having to be used at the same time to be properly assembled on the shell, which limits the user's usage scenarios. For example, the user only wants to cook a single ingredient and has a large capacity requirement, or a small capacity requirement, but the first and second inner pots cannot be used alone.

[0032] 2. The first and second inner pots were assembled without sealing considerations, resulting in an ineffective seal around the rim. This caused air leakage during cooking, resulting in a poor cooking experience. 3. The problem of exhaust from the two second inner pots during cooking was not taken into consideration. The exhaust channel of the first inner pot was blocked, which prevented the steam in the first inner pot from being discharged smoothly, resulting in excessive pressure in the first inner pot, posing a safety hazard.

[0033] Therefore, in order to solve the above problems, this embodiment is proposed.

[0034] The following combination Figures 1 to 13 , describing embodiments of the present invention.

[0035] According to an embodiment of the present invention, on the one hand, the present invention provides a cooking device, including a pot body, the pot body including a support 3, a first inner pot 1, and a second inner pot 2, wherein the first inner pot 1 is detachably arranged in the support 3, the first inner pot 1 has a first pot edge 11, and the first pot edge 11 can be overlapped on the support 3; the second inner pot 2 is detachably arranged in the first inner pot 1, the second inner pot 2 has a second pot edge 21, and the second pot edge 21 can be overlapped on the first pot edge 11 or the support 3; the cooking device has a double-pot usage state in which the first inner pot 1 is overlapped in the support 3 and the second inner pot 2 is overlapped in the first inner pot 1, and a single-pot usage state in which either the first inner pot 1 and the second inner pot 2 is overlapped in the support 3. In the above embodiment, the first inner pot 1 is detachably arranged in the support 3, and the second inner pot 2 is detachably arranged in the first inner pot 1, which is convenient for taking out the first inner pot 1 and the second inner pot 2, and the pot edge of the second inner pot 2 can be overlapped on the pot edge of the first inner pot 1 or the support 3, so that the two inner pots can not only be installed at the same time for zoned cooking, but also when the user needs a large-capacity inner pot for cooking, the first inner pot 1 can be placed alone on the support 3 for use, and when the user needs a small-capacity inner pot for cooking, the second inner pot 2 can be placed alone on the support 3 for use, so that the user can install the two inner pots for use at the same time, and can also install and use each inner pot independently according to actual needs, making the application scenarios of the cooking equipment more diversified, increasing the usage scenarios of the cooking equipment, improving the user experience, and effectively solving the problem that the two inner pots of the existing double-pot cooking equipment must be used at the same time and the user usage scenarios are relatively limited.

[0036] Specifically, a first cooking cavity is formed between the inner wall of the first inner pot 1 and the outer wall of the second inner pot 2, and a second cooking cavity is formed inside the second inner pot 2. The pot body also includes an outer shell and a base disposed within the outer shell, and a support member 3 is mounted on the base for supporting the first inner pot 1 and the second inner pot 2. The pot body also includes a heating structure, which includes a bottom heating coil 91 disposed on the outer wall of the base and a side heating coil 92 disposed on the outer wall of the support member 3. The bottom heating coil 91 and the side heating coil 92 are used to heat the food in the first cooking cavity and the second cooking cavity. The single pot usage state includes a first single pot usage state in which only the first inner pot 1 is disposed within the support member 3, and a second single pot usage state in which the second inner pot 2 is directly disposed within the support member 3.

[0037] An analysis of existing double-pot cooking equipment reveals that the two pots cannot be used independently. The main reasons are as follows: First, due to the width of the pot rim, the pot rim diameter of the inner pot is smaller than the diameter of the support ring, making it impossible to install it independently on the support ring. Second, due to the design of the sealing ring on the lid, the sealing ring on the lid and the design structure and size of the double-pot rim do not take into account how to ensure the pot mouth is sealed when the two pots are used independently, but only consider the sealing when the two pots are installed. Therefore, this embodiment expands on these two aspects and provides a universal pot installation structure design. It can not only install two pots for use at the same time, but also each pot can be installed and used independently according to user needs, while also solving problems such as poor sealing and poor exhaust when cooking with two pots.

[0038] In some embodiments, the support member 3 includes a support ring, and the outer diameters of the first pot rim 11 and the second pot rim 21 are both larger than the diameter of the support ring.

[0039] In the above embodiment, by adopting a design in which the outer diameters of the first pot rim 11 and the second pot rim 21 are both larger than the diameter of the support ring, the first inner pot 1 and the second inner pot 2 can not only be used at the same time, but also ensure that the two inner pots can be independently installed on the support ring for separate use, thereby realizing a universal design of single and double inner pot installation structures, effectively solving the problem that only two inner pots can be used at the same time in existing double-pot cooking equipment, or only the outer inner pot can be used alone and the inner pot cannot be used alone.

[0040] Specifically, combined Figures 1 to 9 As shown, the first pot edge 11 and the second pot edge 21 are outwardly folded flange structures, and the first inner pot 1 and the second inner pot 2 are installed in the cavity in the middle of the support ring. Figure 10 、 Figure 11 As shown, a ring of supporting ribs 31 is provided on top of the support ring to support the pot rim. The first pot rim 11 and the second pot rim 21 are supported and overlapped on the supporting ribs 31. The outer diameters of the first pot rim 11 and the second pot rim 21 are both larger than the diameter of the supporting ribs 31. The provision of the ring-shaped supporting ribs not only provides stable support for the first pot 1 and the second pot 2, but also makes it easier to remove the first pot 1 and the second pot 2.

[0041] In some embodiments, the outer diameter of the second pot rim 21 is greater than the outer diameter of the first pot rim 11 .

[0042] In the above embodiment, by setting the outer diameter of the second pot edge 21 to be larger than the outer diameter of the first pot edge 11, not only can the sealing of the second inner pot 2 and the reliability and stability of the installation of the first inner pot 1 and the second inner pot 2 be ensured when the two inner pots are used at the same time, but it can also make it more convenient for the user to take the first inner pot 1 out of the second inner pot 2.

[0043] In some embodiments, combined Figure 8 and Figure 9 As shown, a vent hole 210 is provided on the second pot edge 21; when the cooking device is in a double pot use state, the vent hole 210 is communicated with the interior of the first inner pot 1.

[0044] In the above embodiment, the vent holes 210 provided on the second pot edge 21 allow the steam inside the first inner pot 1 to be discharged normally, effectively ensuring the air pressure balance in the two inner pots during double-pot cooking and preventing food from overflowing.

[0045] Preferably, there are multiple vent holes 210, spaced apart along the circumference of the second pot edge 21. More preferably, the vent holes 210 are evenly spaced apart. The multiple vent holes 210 further ensure balanced air pressure throughout the first cooking cavity, preventing the vent holes 210 from being concentrated on one side of the first cooking cavity, leading to excessive air pressure on the other side.

[0046] In some embodiments, combined Figure 6 and Figure 7 As shown, a supporting flange 111 is provided on the outer peripheral side of the first pot edge 11, and the supporting flange 111 is used to support the second pot edge 21; a first sealing structure 4 is provided on the supporting flange 111, and the first sealing structure 4 is used to seal the fitting gap between the first pot edge 11 and the second pot edge 21. In the above embodiment, when two inner pots are used at the same time, the rim of the first inner pot 1 is directly placed on the support ring, and the second inner pot 2 is placed in the middle of the first inner pot 1, so that different foods can be cooked in different areas. The rim of the second inner pot 2 can be supported by the support flange 111 set on the outer peripheral side of the rim of the first inner pot 1, and the first sealing structure 4 set on the support flange 111 can seal the first pot rim 11 and the second pot rim 21 to prevent steam leakage from the side and ensure the cooking effect.

[0047] Specifically, the supporting flange 111 is provided on the upper surface of the first pot rim 11 . Preferably, the supporting flange 111 is formed by folding the outer peripheral edge of the first pot rim 11 upward.

[0048] Furthermore, the first sealing structure 4 is an annular member, preferably a sealing ring or a sealing gasket. An annular groove is provided on the bottom wall of the first sealing structure 4, and the annular groove is clamped on the support flange 111. Preferably, the depth of the annular groove is the same as the height of the support flange 111, so that the first sealing structure 4 can be stably clamped on the support flange 111.

[0049] In some embodiments, the cooking device further comprises a lid, which has a closed state (closed to close the pot body) and an open state (open to open the pot body). The lid includes an insulating cover assembly, which is located on the side of the lid closest to the pot body and is provided with a vent 50. When the cooking device is in dual-pot mode and the lid is closed, a gap is formed between the insulating cover assembly and the second pot rim 21, forming a steam discharge channel connecting the vent 210 on the second pot rim 21 and the vent 50.

[0050] In the above embodiment, the heat-insulating cover plate 5 provided above the inner pot can seal the pot opening, thereby preventing a large amount of water loss during cooking. Furthermore, the vent holes 50 provided on the heat-insulating cover plate assembly allow the water vapor generated during cooking to be discharged through the vent holes 50 of the heat-insulating cover plate 5 and the air outlet 80 on the upper cover 8 of the pot lid. In addition, by forming a steam discharge channel between the heat-insulating cover plate 5 and the second pot rim 21, when two inner pots are used simultaneously, the steam inside the first inner pot 1 can be discharged through the vent holes 210 on the second pot rim 21 and the steam discharge channel, allowing the steam inside the first inner pot 1 to be discharged normally, effectively ensuring the air pressure balance in the two inner pots during double-pot cooking, and preventing the food from heating and overflowing.

[0051] Specifically, the pot lid also includes an upper cover 8, which is provided with an air outlet 80. The thermal insulation cover assembly includes an insulating cover plate 5, which has an exhaust area provided at a position corresponding to the air outlet 80. The exhaust area is provided with multiple exhaust holes 50. When both inner pots are used simultaneously, the steam in the first inner pot 1 is discharged to the external environment through the vent holes 210 on the second pot rim 21, the steam discharge channel, the exhaust holes 50 on the insulating cover plate 5, and the air outlet 80 on the upper cover 8.

[0052] In some embodiments, the thermal insulation cover assembly further includes a second sealing structure 6 , which is mounted on the thermal insulation cover 5 and is used to seal the first inner liner 1 or the second inner liner 2 .

[0053] In the above embodiment, by providing a second sealing structure 6 on the heat-insulating cover plate 5, the pot edge of the first inner pot 1 or the second inner pot 2 can be sealed, thereby effectively ensuring the sealing and reliability of the first inner pot 1 or the second inner pot 2, and ensuring the air pressure balance in the two inner pots during cooking.

[0054] In some embodiments, the second sealing structure 6 is an annular seal; when the cooking device is in a double-pot use state and the pot lid is in a closed state, the second sealing structure 6 is pressed against the top surface of the second pot rim 21, and the vent 210 is located on the inner circumference of the second sealing structure 6; when the cooking device is in a single-pot use state and the pot lid is in a closed state, the second sealing structure 6 is pressed against the top surface of the first pot rim 11 or the second pot rim 21 accordingly. In the above embodiment, by positioning the vent holes 210 on the second pot rim 21 inside the second sealing structure 6, steam leakage from the side of the pot rim is effectively prevented, while ensuring that steam within the first pot can be smoothly discharged through the vent holes 210 and the steam exhaust channel. Furthermore, whether the cooking device is in dual-pot mode or single-pot mode, the second sealing structure 6 can press against the top surface of the first pot rim 11 or the second pot rim 21, effectively ensuring sealing and reliability when both pots are used simultaneously or when either pot is used alone.

[0055] In some embodiments, the second sealing structure 6 includes an elastic sealing portion 61, which has a compressed state and an uncompressed state. The bottom of the elastic sealing portion 61 has an annular sealing surface 60 adapted to abut against the top surface of the first pot rim 11 or the second pot rim 21. When the pot lid is in the closed state, the elastic sealing portion 61 is compressed and abuts against the top surface of the first pot rim 11 or the second pot rim 21, and the abutment width of the annular sealing surface 60 with the first pot rim 11 or the second pot rim 21 is no less than 3 mm. By setting the horizontal overlap width W of the second sealing structure 6 with the first pot rim 11 and the second pot rim 21 to be no less than 3 mm, the reliability of the circumferential seal of the first inner pot 1 and the second inner pot 2 can be effectively ensured.

[0056] In some embodiments, combined Figure 3 As shown, the vertical distance between the annular sealing surface 60 of the elastic sealing portion 61 in the uncompressed state and the bottom surface of the thermal insulation cover 5 is set to d1; when the first inner liner 1 is overlapped in the support member 3, the vertical distance between the top surface of the first pot edge 11 and the bottom surface of the thermal insulation cover 5 is set to d2, wherein d1-d2≥1mm; when the second inner liner 2 is overlapped in the support member 3, the vertical distance between the top surface of the second pot edge 21 and the bottom surface of the thermal insulation cover 5 is set to d3, wherein d1-d3≥1mm.

[0057] By adopting the above-mentioned size design, whether cooking with two inner pots at the same time or using either inner pot alone for cooking, it can be ensured that the annular sealing surface 60 of the elastic sealing part 61 can fit against the first pot edge 11 or the second pot edge 21, thereby ensuring the sealing reliability of the first inner pot 1 and the second inner pot 2 in the axial direction.

[0058] In some embodiments, the second sealing structure 6 is a sealing sleeve, and the elastic sealing portion 61 is an annular structure with at least one bend. Preferably, in this embodiment, the elastic sealing portion 61 is an annular structure with a horizontal U-shaped or C-shaped longitudinal cross-section, and the U-shaped or C-shaped elastic sealing portion 61 opens toward the center of the cooking equipment. The bottom of the elastic sealing portion 61 has a sealing section. Preferably, the sealing section is horizontally arranged, and the bottom surface of the sealing section constitutes an annular sealing surface 60. The width of the sealing section is not less than 3 mm.

[0059] In some embodiments, the second sealing structure is clamped on the insulation cover plate 5. To be precise, the insulation cover plate assembly also includes a cover plate bracket 7, which is arranged on the outer peripheral side of the insulation cover plate 5 and is used to install and fix the insulation cover plate 5 and the second sealing structure 6. The second sealing structure 6 is clamped on the cover plate bracket 7 for easy disassembly and assembly.

[0060] In some embodiments, combined Figures 1 to 5 、 Figure 12 and Figure 13 As shown, the second sealing structure 6 includes a mounting portion 62, and the mounting portion 62 is clamped on the cover bracket 7. The thermal insulation cover 5 includes a cover body and an annular pressing edge arranged on the outer periphery of the cover body, and the annular pressing edge presses the mounting portion 62 tightly on the cover bracket 7; the cover bracket 7 is provided with a clamping hole 73, and the outer periphery of the annular pressing edge is provided with a cover claw 51, and the cover claw 51 is inserted into the clamping hole 73, and the end is bent inward and tightly clamped on the cover bracket 7.

[0061] In the above embodiment, the cover plate body is a flat plate structure, and the annular pressure edge is formed by extending the outer peripheral wall of the cover plate body upward by a set length and then extending toward the outer peripheral side. The annular pressure edge presses the mounting portion 62 of the second sealing structure 6 against the cover plate bracket 7 to prevent the second sealing structure 6 from falling off. By providing the cover plate clamping claw 51, inserting the cover plate clamping claw 51 into the clamping hole 73, and bending the end of the cover plate clamping claw 51 inward and clamping it against the cover plate bracket 7, the second sealing structure 6 is pressed between the thermal insulation cover plate 5 and the cover plate bracket 7, thereby achieving effective fixation of the thermal insulation cover plate 5, the second sealing structure 6 and the cover plate bracket 7, ensuring the stability of the three, and further reducing the risk of the second sealing structure 6 falling off or shifting.

[0062] Furthermore, the mounting portion 62 includes a mounting body and a snap-fit ​​flange 621. The longitudinal cross-section of the mounting body is a 7-shaped ring structure. The upper end of the elastic sealing portion 61 extends upward by a set length and then bends toward the outer peripheral side to form the mounting body. One end of the mounting body is connected to the upper end of the elastic sealing portion 61, and the other end is folded downward to form the snap-fit ​​flange 621. The cover bracket 7 is an annular part. The cover bracket 7 is used to install and fix the thermal insulation cover 5 and the second sealing structure 6. The cover bracket 7 is located at the outer periphery of the thermal insulation cover 5. The inner periphery of the cover bracket 7 is provided with an annular clamping protrusion 70. The mounting portion 62 is clamped on the clamping protrusion 70. A first clamping groove 71 is provided above the clamping protrusion 70. The first clamping groove 71 is a groove structure arranged on the top wall of the clamping protrusion 70. The first clamping groove 71 is located on the outer periphery of the clamping protrusion 70. During assembly, the mounting body is clamped on the clamping protrusion 70, and the clamping flange 621 is clamped in the first clamping groove 71. The thermal insulation cover 5 presses the mounting portion 62 to fix it on the cover bracket 7.

[0063] The lock body 7 is fixed with the locking cam 72 at the bottom, and the locking cam 73 is fixed with the locking cam 74 at the bottom, so that the locking cam 73 is locked.

[0064] In this embodiment, the heat-insulating cover plate 5 and the second sealing structure 6 are assembled into one body as a heat-insulating cover plate assembly by means of the provided cover plate bracket 7, so as to seal the first inner pot 1 and the second inner pot 2 and prevent steam from flowing out from the side edges of the inner pots. The snap-fit ​​flange 621 of the second sealing structure 6 is inserted into the first slot 71 of the cover plate bracket 7, and then the cover plate claw 51 of the heat-insulating cover plate 5 is inserted into the slot 73 of the cover plate bracket 7, and then the end of the cover plate claw 51 is bent and pressed into the second slot 72 of the cover plate bracket 7, thereby pressing the second sealing structure 6 between the heat-insulating cover plate 5 and the cover plate bracket 7, and then the heat-insulating cover plate 5 is pressed into the second slot 72 of the cover plate bracket 7. Figures 1 to 5 、 Figure 12 and Figure 13 As shown, the lower end of the cover plate claw 51 is bent to the right and clamped into the second clamping groove 72, and the cover plate claw 51 is clamped on the clamping protrusion 70 of the cover plate bracket 7, thereby achieving effective fixation of the second sealing structure 6, and the thermal insulation cover plate 5 and the second sealing structure 6 are more stable.

[0065] In some embodiments, the cooking device is a rice cooker or a pressure cooker.

[0066] Preferably, in this embodiment, the cooking device is an electric rice cooker.

[0067] This embodiment provides a rice cooker with two inner pots, which can realize zoned cooking of food and solve the problems of poor sealing and poor exhaust when cooking with a double-pot rice cooker. In addition, a universal rice cooker inner pot installation structure design is provided, so that the rice cooker can be installed with two pots at the same time, and each pot can be installed and used independently according to user needs.

[0068] The specific structure and assembly process of the cooking device provided in this embodiment are generally introduced below with reference to the accompanying drawings.

[0069] like Figures 1 to 5As shown, the first inner pot 1 and the second inner pot 2 can be independently installed in the cavity in the middle of the support member 3, and the pot edge is supported by a circle of supporting ribs 31 provided on the support member 3. When the double inner pot is installed for use, the pot edge of the first inner pot 1 is directly placed on the supporting ribs 31. The outer peripheral side of the pot edge of the first inner pot 1 is provided with an upward supporting flange 111 to support the pot edge of the second inner pot 2. The supporting flange 111 of the first inner pot 1 is provided with a first sealing structure 4 to seal the pot edges of the second inner pot 2 and the first inner pot 1 to prevent steam leakage from the side. The second inner pot 2 is placed in the middle of the first inner pot 1, and different foods can be cooked in different areas. The width of the second pot edge 21 needs to be larger than the width of the first pot edge 11 to ensure reliable sealing and installation while making it convenient for users to take the second inner pot 2 out of the first inner pot 1.

[0070] Furthermore, an insulation cover assembly is provided above the inner pot to seal the pot opening and prevent significant moisture loss during cooking. The insulation cover 5 is provided with a plurality of vent holes 50, through which steam generated during cooking can be discharged through the vent holes 50 of the insulation cover 5 and the air outlet 80 of the upper cover 8. To allow steam from the first inner pot 1 to be properly discharged, a plurality of vent holes 210 are provided around the pot edge of the second inner pot 2. This allows steam from the first inner pot 1 to be discharged through the second inner pot 2 and the steam discharge channel, ensuring pressure balance in the two inner pots during dual-pot cooking and preventing overflow from heating.

[0071] Furthermore, a second sealing structure 6 is installed around the circumference of the heat-insulating cover plate 5 to seal the edge of the inner pot ( Figures 1 to 5 、 Figures 12 to 13 The second sealing structure 6 is shown in its uncompressed state. When the lid is closed for cooking, the second sealing structure 6 is compressed, with the annular sealing surface 60 of the compressed second sealing structure 6 abutting the top surface of the second pot rim 21. The vent 210 provided in the second pot rim 21 is located inside the second sealing structure 6 to similarly prevent steam leakage from the sides. This solution enables dual-pot cooking with separate compartments, while ensuring a reliable seal and balanced air pressure within the two pots during cooking.

[0072] Furthermore, the present application takes into account the universal structural design of single and double inner pot installation, so that the cooking device can not only install two inner pots at the same time for zoned cooking, but also when the user needs a large-capacity inner pot for cooking, the first inner pot 1 can be installed alone in the rice cooker for use, and when the user needs a small-capacity inner pot for cooking, the second inner pot 2 can be installed alone in the rice cooker for use. The specific design is as follows: Combine Figures 1 to 5 As shown, the diameter of the first pot edge 11 and the outer diameter of the first pot edge 11 support the diameter of the rib 31, ensuring that the two inner pots can be independently installed on the support ring, combined with Figure 3As shown, the horizontal contact width W between the second sealing structure 6 and the first pot rim 11 or the second pot rim 21 is 3 mm or greater, ensuring a reliable circumferential seal. The dimensional chain is calculated based on the reserved assembly clearances and dimensional tolerances of each component to ensure that the seal between the second sealing structure 6 and the first pot rim 11 or the second pot rim 21 is greater than zero under extreme tolerance conditions. A contact width W of at least 3 mm is required.

[0073] Further, combined with Figure 3 As shown, the vertical distance between the annular sealing surface 60 of the elastic sealing portion 61 in the uncompressed state and the bottom surface of the thermal insulation cover 5 is set to d1, and when the first inner pot 1 is overlapped in the support 3, the vertical distance between the top surface of the first pot edge 11 and the bottom surface of the thermal insulation cover 5 is set to d2, d1-d2≥1mm, and similarly, when the second inner pot 2 is independently installed on the support 3 (not shown in the figure), the vertical distance between the top surface of the second pot edge 21 and the bottom surface of the thermal insulation cover 5 is d3, d1-d3≥1mm. In this way, whether two inner pots are used for cooking at the same time or any inner pot is used alone for cooking, the sealing reliability in the height direction can be guaranteed, and the sealing amount in the height direction of the second sealing structure 6 and the first pot edge 11 and the second pot edge 21 can be ensured to be greater than zero.

[0074] In this embodiment, when used as a double inner pot or when the second inner pot 2 is installed and used independently, the annular sealing surface 60 of the second sealing structure 6 is compressed to a position abutting the top surface of the second pot edge 21 to achieve sealing. When the first inner pot 1 is installed and used independently, the annular sealing surface 60 of the second sealing structure 6 is compressed to a position abutting the top surface of the first pot edge 11 to achieve sealing.

[0075] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations shall fall within the scope of protection of the embodiments of the present application.
