Description

Technical Field

[0001] The utility model relates to a cooking utensil. Background Art

[0002] Existing double-boiler cooking appliances including pressure cookers have different cooking pressures in the two pots, and the structures of the insulation covers corresponding to the pots are also different. The assembly positions and methods on the middle plate are different, resulting in uneven force on the middle plate of the pressure cooker and rice cooker. When the middle plate is shared, the different forces may easily cause deformation of the middle plate.

[0003] Therefore, it is necessary to provide a cooking appliance to at least partially solve the above problems. Utility Model Content

[0071] Unless otherwise stated, numerical ranges herein include not only the entire range between its two endpoints but also the several sub-ranges contained therein.

[0072] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0073] The present invention provides a cooking appliance. The dual-pot configuration of the cooking appliance allows the user to perform multiple cooking operations simultaneously, improving cooking efficiency and shortening cooking time. The cooking appliance can function as an electric rice cooker and / or an electric pressure cooker to meet diverse cooking needs. In addition to cooking rice, it can also be used for cooking porridge, soup, steaming vegetables, stewing meat, and other various other functions.

[0074] The following will be combined Figures 1 to 5 The cooking appliance according to the present invention is described in detail.

[0075] like Figure 1-Figure 2 As shown, the cooking appliance primarily comprises a pot body 100 and a lid 200, which is arranged to open and close above the pot body 100. The pot body 100 has two cylindrical pot storage compartments. The pot is fixedly mounted in the pot storage compartments, or it can be freely inserted and removed from the pot storage compartments for easy cleaning. The pot is typically made of metal and has a circular opening on its top surface for holding ingredients to be heated, such as rice or soup. The pot body 100 also includes a pot heating device and a control device. The pot heating device can be located at the bottom of the pot to heat the food inside, and the user can control the cooking operation of the cooking appliance through the control device. Optionally, the pot heating device can be configured as two independent heater components, one for each pot. The two heaters can operate independently or simultaneously, allowing the double pot cooking appliance to perform two or the same cooking functions.

[0076] The pot body 100 may include a housing 110 and a base 120 located at the lower side of the housing 110. The lower end of the housing 110 may be connected to the base 120 by any suitable means such as snap connection, plug connection, or fastening connection with fasteners such as screws.

[0077] Optionally, a middle plate 400 is provided at the upper end of the housing 110. The upper end of the housing 110 can be connected to the middle plate 400 by any suitable means, such as snap-fitting, plug-in connection, or fastening with fasteners such as screws. Optionally, the middle plate 400 and the base 120 can be connected. For example, the middle plate 400 can be provided with a downwardly extending support column 430, and the base 120 can be provided with an upwardly extending hollow screw column. The screw can be inserted from the bottom of the screw column and partially exit from the top of the screw column to be tightened to the support column 430.

[0078] The lid 200 has a shape substantially corresponding to the pot body 100. Accordingly, two lids 200 are provided corresponding to the two inner pots. The lid 200 is disposed on the pot body 100 in an openable and closable manner. Specifically, it is pivotally connected to the pot body 100 via a pivot shaft and can freely pivot about a pivot axis located on the pivot shaft between a closed position and an open position relative to the pot body 100, thereby facilitating the closing and opening of the pot body 100. When the lid 200 is closed on the pot body 100, it covers the inner pot body and defines a cooking space between the lid 200 and the inner pot body. Optionally, the two lids 200 can be opened and closed independently, or they can be integrated and opened and closed simultaneously. The lid 200 also typically has a pot mouth sealing ring, which can be made of, for example, a rubber material. This sealing ring is disposed between the lid 200 and the inner pot body to seal the cooking space when the lid 200 is closed. It can be understood that when the two covers 200 are combined with the two pot cores, two independent and relatively sealed cooking spaces are formed.

[0079] It should be noted that directional terms used herein to describe various components and parts of the pot body 100, such as "up," "down," "above," "below," "upward," "downward," "upward," and "downward," are relative to the pot body 100 when it is horizontally placed and upright. Unless otherwise specified, in the directional terms "inward," "outward," "inwardly," "outwardly," "inside," and "outside," "inside," and "outside," "inside" refers to a direction closer to the center of the pot body 100, and "outside" refers to a direction further away from the center of the pot body 100.

[0080] In the present invention, the inner pot includes a first inner pot 310 and a second inner pot 320. The lid 200 includes the first lid 210 and the second lid 220. A first cooking space 211 suitable for pressure cooking is formed between the first inner pot 310 and the lid 210. A second cooking space 221 suitable for normal pressure cooking is formed between the second inner pot 320 and the lid 220. The middle plate 400 forms a structure suitable for mounting the two inner pots.

[0081] In this solution, in order to reduce heat loss during the cooking process and to avoid mutual influence between the two pots during the cooking process, a heat insulation cover is provided on the periphery of each pot. Optionally, the heat insulation cover is connected to the middle plate 400. The heat insulation cover includes a first heat insulation cover 510 and a second heat insulation cover 520. In the projection along the height direction of the cooking utensil, the first heat insulation cover 510 and the second heat insulation cover 520 are symmetrically arranged. The first heat insulation cover 510 and the second heat insulation cover 520 can share a middle plate 400, which not only improves the overall structural compactness of the cooking utensil, but also optimizes the manufacturing cost and user experience.

[0082] To facilitate pressure cooking in the first inner pot 310, the lid 200 and pot body 100 must be tightly coupled. Optionally, after closing the lid, the first lid 210 and the first inner pot 310, or the first lid 210 and the first heat-insulating cover 510, need to be engaged by a structure such as a claw. In this embodiment, the first lid 210 and the first heat-insulating cover 510 are engaged by a claw. Therefore, the first heat-insulating cover 510 is required to be as close to the first lid 210 as possible. In this embodiment, the top edge of the first heat-insulating cover 510 is higher than the top edge of the second heat-insulating cover 520.

[0083] Based on the above, in order to ensure that the middle plate 400 does not deform or warp, it is necessary to keep the center of gravity heights of the first heat-insulating cover 510 and the second heat-insulating cover 520 basically consistent. Since the first cover 210 and the first heat-insulating cover 510 are engaged with each other so that the pressures in the cooking space offset each other, the middle plate 400 is mainly subjected to gravity. In this solution, the spacing between the bottom of the first heat-insulating cover 510 and the bottom of the outer shell 110 and the height difference between the bottom of the second heat-insulating cover 520 and the outer shell 110 do not exceed 10 mm. The outer shell 110 and the middle plate 400 provide direct support for the heat-insulating cover, wherein the height difference between the first heat-insulating cover 510 and the second heat-insulating cover 520 and the bottom of the outer shell 110 is maintained within 10 mm, ensuring the balance of the bottom of the cooking utensil and reducing safety hazards caused by shaking or overturning. In this solution, since the first thermal insulation cover 510 and the second thermal insulation cover 520 are symmetrically distributed in the horizontal direction, and the height difference between their bottoms and the bottom of the outer shell 110 is extremely small, the force applied to the middle plate 400 in the horizontal direction is relatively uniform; since the bottoms of the first thermal insulation cover 510 and the second thermal insulation cover 520 are balanced, the force applied to the middle plate 400 in the vertical direction is relatively uniform; therefore, the forces on both sides of the middle plate 400 are uniform, reducing the risk of deformation of the middle plate 400 due to uneven forces.

[0084] In this solution, the height difference between the bottom of the insulation cover and the bottom of the outer shell is limited to within 10mm, which helps reduce the risk of tipping due to unstable center of gravity. The 10mm height difference also facilitates the implementation of the manufacturing process and the control of assembly accuracy.

[0085] In some embodiments of the present application, reference is made to Figure 2 , the height difference h1 between the bottom of the first heat-insulating cover 510 and the bottom of the outer shell 110 is greater than or equal to 25 mm. The height difference h2 between the bottom of the second heat-insulating cover 520 and the bottom of the outer shell 110 is greater than or equal to 25 mm. During the heating process of the cooking utensil, especially during high-pressure cooking, the internal temperature will rise sharply. If there is not enough height difference between the heat-insulating cover and the bottom of the outer shell 110, the outer shell 110 may be deformed due to direct heat, thereby affecting the use effect and life of the entire cooking utensil. Optionally, the terminal block is located below the heat-insulating cover and above the bottom of the outer shell 110. The height difference between the heat-insulating cover and the outer shell 110 provides a certain heat dissipation space for the terminal block, ensuring that it has sufficient heat dissipation space and avoiding direct contact between the terminal block and other components in the space.

[0086] like Figure 3-Figure 5 As shown, the middle plate 400 has a first opening 401, a first mounting portion 410 extending circumferentially around the first opening 401, a second opening 402, and a second mounting portion 420 extending circumferentially around the second opening 402. Thus, the middle plate 400 forms a structure suitable for mounting two pots.

[0087] The first heat-insulating cover 510 is located in the first opening 401. That is, the first heat-insulating cover 510 is installed to the pot body 100 via the first opening 401. The top edge of the first heat-insulating cover 510 extends radially outward to form a first edge 511, and at least part of the first edge 511 is located above the first mounting portion 410. Optionally, the first heat-insulating cover 510 is used to install the first pot inner body 310. The first pot inner body 310 is suitable for pressure cooking. In order to meet the requirements of pressure cooking, the first heat-insulating cover 510 usually needs to cooperate with the hardware of the cover body 200 to withstand internal pressure. In the present utility model, the first heat-insulating cover 510 is arranged above the middle plate 400. Specifically, the edge of the first heat-insulating cover 510 is located above the first mounting portion 410. Under the premise of ensuring the connection strength of the first heat-insulating cover 510, sufficient support force is provided for the first heat-insulating cover 510, which is crucial for withstanding the internal pressure generated during pressure cooking, ensuring the safety and reliability of the pressure cooking process.

[0088] The second heat-insulating cover 520 is located within the second opening 402. That is, the second heat-insulating cover 520 is mounted to the pot body 100 via the second opening 402. The top edge of the second heat-insulating cover 520 extends radially outward to form a second edge 521, and the second edge 521 is connected to the second mounting portion 420. Optionally, the second heat-insulating cover 520 is used to mount the second pot 320. The second pot 320 is suitable for normal pressure cooking. During normal pressure cooking, the second heat-insulating cover 520 does not need to cooperate with the second pot 320, and the pressure during normal pressure cooking is generally lower than that during pressure cooking (specifically, high-pressure cooking). In the present invention, in order to save costs, the second heat-insulating cover 520 can be set below the plane. Specifically, the second mounting portion 420 has a mounting groove 421, and at least a portion of the second edge 521 is located within the mounting groove 421. The force point of the second heat-insulating cover 520 is located within the mounting groove 421, that is, at the lower part of the upper surface of the middle plate 400.

[0089] As can be seen from the above, the first heat-insulating cover 510 is used to mount the first inner pot 310. The second heat-insulating cover 520 is used to mount the second inner pot 320. Thus, the inner pot storage portion of the pot body 100 is formed in the heat-insulating cover, and the inner pot can be freely placed in or taken out of the inner pot storage portion.

[0090] Thus, by coordinating the first mounting portion 410 with the first heat-insulating cover 510, the edge of the first heat-insulating cover 510 is positioned above the first mounting portion 410. Leveraging the support provided by the middle plate 400, the first heat-insulating cover 510 can safely withstand the internal high pressure generated during cooking, ensuring the safety and reliability of the cooking process. The second mounting portion 420, through the provision of the mounting groove 421, allows a portion of the edge of the second heat-insulating cover 520 to be directly embedded within the mounting groove 421, simplifying the installation process and reducing the need for additional connectors and fixings, further reducing costs. Furthermore, the second edge 521 can be positioned at a lower height, saving material costs for the second heat-insulating cover 520.

[0091] In some embodiments, the upper end of the mounting groove 421 is not closed, that is, the mounting groove 421 has a bottom wall and side walls, and the second edge 521 is overlapped to the bottom wall. In other embodiments, the upper end of the mounting groove 421 is closed, that is, the mounting groove 421 has a top wall, a bottom wall and side walls, and the second edge 521 can be screwed in from the side of the mounting groove 421, thereby overlapping to the bottom wall of the mounting groove 421. The height and shape of the mounting groove 421 match the second edge 521, so that the second edge 521 can be stably installed in the mounting groove 421. The structure of the double-layer groove wall provides stable support and positioning for the second edge 521, preventing it from shaking or falling off during the cooking process. When installing the second thermal insulation cover 520, the user only needs to align the second edge 521 and snap it into the mounting groove 421 to complete the installation.

[0092] In some embodiments of the present invention, at least two support columns 430 are located between the first opening 401 and the second opening 402. A support portion is provided between the first opening 401 and the second opening 402 to prevent the middle of the middle plate 400 from being crushed by the heat insulation cover and the pot body on both sides, thereby being able to better bear the load. Figure 5 Two support columns 430 are located between the first opening 401 and the second opening 402, two support columns 430 are located on the left side of the first opening 401, and two support columns 430 are located on the right side of the second opening 402. By setting up multiple support columns 430, the middle plate 400 is subjected to uniform force.

[0093] On the basis of the above embodiment, the inner pot is removable and placed in the pot body 100. In this solution, in order to facilitate the user to take and put, there is a gap between the inner pot and the heat preservation cover, so that the user can more easily grasp the edge of the inner pot when lifting the inner pot. Figure 4 The height difference h3 between the first pot edge 311 and the first edge 511 is greater than or equal to 10 mm. The height difference h4 between the second pot edge 321 and the second edge 521 is greater than or equal to 10 mm.

[0094] Optionally, the top edge of the first pot body 310 is above the middle plate 400. That is, the first pot edge 311 is located above the middle plate 400. This further facilitates the user to take and put.

[0095] Optionally, the top edge of the second pot 320 is above the middle plate 400. That is, the second pot edge 321 is located above the middle plate 400. This further facilitates the user's access.

[0096] In some embodiments of the present invention, the cooking appliance further includes a first heating plate 610, which is located below the first inner pot 310 and is adapted to abut against the first inner pot 310. The first heating plate 610 can generate heat quickly, thereby shortening cooking time.

[0097] In some embodiments of the present invention, the cooking appliance further includes a second heating plate 620, which is located below the second inner pot 320 and is adapted to abut against the second inner pot 320. The second heating plate 620 can generate heat quickly, shortening cooking time.

[0098] As can be seen from the above, the top edge of the first heat-insulating cover 510 is higher than the top edge of the second heat-insulating cover 520. The height difference between the first heat-insulating cover 510 and the first pot core 310, and the height difference between the second heat-insulating cover 520 and the second pot core 320 are similar. At the same time, the spacing between the bottom of the first heat-insulating cover 510 and the bottom of the outer shell 110 is equal to the spacing between the bottom of the second heat-insulating cover 520 and the bottom of the outer shell 110. When the first pot core 310 and the second pot core 320 are similar in size, the spacing between the bottom of the first pot core 310 and the bottom of the second heat-insulating cover 520 is larger. In order to ensure the heating effect of the first heating plate 610, the first heating plate 610 needs to be raised accordingly, that is, the first heating plate 610 is spaced apart from the bottom of the outer shell 110.

[0099] On the basis of the above embodiment, a fixing column 611 is provided between the first heating disk 610 and the bottom of the first heat preservation cover 510. The setting of the fixing column 611 is mainly to support and fix the first heating disk 610 to ensure its stability and safety during operation. Optionally, a plurality of fixing columns 611 are evenly distributed between the first heating disk 610 and the first heat preservation cover 510. By providing a plurality of fixing columns 611, it is ensured that the first heating disk 610 is subjected to a balanced support force to prevent it from shaking or tilting during operation.
