Description

Technical Field

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

[0002] Most current cooking appliances use a single inner pot design, which means they can only cook food using the same cooking conditions at a time. Users who need to cook food using different cooking conditions must use multiple cooking utensils. Existing multi-pot cooking appliances either share a single lid or each pot has its own lid. In multi-pot cooking appliances with a single lid, opening the lid when cooking in multiple pots simultaneously can affect cooking results. In multi-pot cooking appliances with multiple independent lids, adjacent lids can easily interfere with each other when opened.

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

[0091] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0092] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0093] Unless otherwise stated, numerical ranges herein include not only the entire range between its two endpoints but also the several sub-ranges contained therein.

[0094] 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.

[0095] 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.

[0096] The following will be combined Figures 1 to 7 The cooking appliance according to the present invention is described in detail.

[0097] like Figures 1 to 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 at least two cylindrical pot storage compartments. The pot is fixedly mounted in the pot storage compartments, or 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 upper 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 at least two independent heater components, one corresponding to the pot body. Each heater can operate independently or simultaneously, allowing the cooking appliance to perform multiple or the same cooking functions.

[0098] 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.

[0099] Optionally, a middle plate 400 is provided at the upper end of the pot body 100. Specifically, the middle plate 400 is connected to the upper end of the outer shell 110. The upper end of the outer shell 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, and the base 120 can be provided with an upwardly extending hollow screw column. The screw can be inserted from the underside of the screw column and partially exit from the top of the screw column to be tightened to the support column.

[0100] The lid 200 has a shape substantially corresponding to the pot body 100. Accordingly, at least two lids 200 are provided, one corresponding to each of the at least 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 along which the pivot shaft lies between a closed position and an open position relative to the pot body 100, thereby facilitating 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 101 between the lid 200 and the inner pot body. Optionally, each lid 200 can be opened and closed independently. The lid 200 also typically includes a pot mouth sealing ring 230, which can be made of, for example, a rubber material. The pot mouth sealing ring 230 is disposed between the lid 200 and the inner pot body to seal the cooking space 101 when the lid 200 is closed. It can be understood that when the cover 200 is closed over the pot, at least two independent and relatively sealed cooking spaces 101 are formed.

[0101] 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.

[0102] The utility model is described by taking a double-boiler cooking utensil as an example.

[0103] like Figure 2 As shown, the pot inner portion includes a first pot inner portion 310 and a second pot inner portion 320. The lid 200 includes the first lid 210 and the second lid 220. The first pot inner portion 310 cooperates with the first lid 210 for pressure cooking. The second pot inner portion 320 cooperates with the second lid 220 for normal pressure cooking. The middle plate 400 forms a structure suitable for mounting the two pot inner portions.

[0104] In this embodiment, to reduce heat loss during cooking and prevent the two inner pots from interfering with each other during cooking, a heat shield is provided around the periphery of each inner pot. Optionally, the heat shield is connected to the middle plate 400. Optionally, the middle plate 400 provides direct support for the heat shield.

[0105] The heat preservation cover includes a first heat preservation cover 510 and a second heat preservation cover 520. The first heat preservation cover 510 and the second heat preservation cover 520 can share a middle plate 400, which not only improves the overall structural compactness of the cooking utensil, but also optimizes manufacturing costs and user experience.

[0106] like Figure 3 As shown, the top edge of the first heat-insulating cover 510 extends radially outward to form a first edge 511. As can be seen from the above, 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 first cover body 210 to withstand internal pressure. In the present utility model, the first heat-insulating cover 510 is arranged above the middle plate 400 to facilitate the cooperation with the hardware. Under the premise of ensuring the connection strength of the first heat-insulating cover 510, sufficient supporting force is provided for the first heat-insulating cover 510, which is crucial for withstanding the internal pressure generated during pressure cooking, and ensures the safety and reliability of the pressure cooking process.

[0107] The top edge of the second heat-insulating cover 520 extends radially outward to form a second edge 521. As can be seen from the above, the second heat-insulating cover 520 is used to install the second pot inner 320. The second pot inner 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 inner 320, and the pressure during normal pressure cooking is generally lower than the pressure during pressure cooking (specifically high-pressure cooking). In the present utility model, in order to save costs, the edge of the second heat-insulating cover 520 can be hidden under the middle plate 400, which improves the aesthetics while achieving the fixation of the second heat-insulating cover 520. Optionally, a mounting groove 410 is opened in the middle plate 400, and at least part of the second edge 521 is located in the mounting groove 410. The force point of the second heat-insulating cover 520 is located in the mounting groove 410, that is, below the upper surface of the middle plate 400. Part of the edge of the second heat-insulating cover 520 can be directly embedded in the installation groove 410, which not only simplifies the installation process, but also reduces the need for additional connectors and fixings, further reducing costs. At the same time, the second edge 521 can be set at a lower height, saving the material cost of the second heat-insulating cover 520.

[0108] Optionally, the pot body receiving portion of the pot body 100 is formed in the heat-insulating cover, and the pot body can be freely placed in or taken out of the pot body receiving portion. In other embodiments, the pot body can be fixed in the pot body receiving portion.

[0109] As can be seen above, the top edge of the first heat-insulating cover 510 is higher than the middle plate 400. The top edge of the second heat-insulating cover 520 is lower than the middle plate 400. The first heat-insulating cover 510 is higher than the second heat-insulating cover 520. In some embodiments, the height difference between the first pot 310 and the second pot 320 is not much. When the first pot 310 and the second pot 320 are placed in the first heat-insulating cover 510 and the second heat-insulating cover 520, respectively, the top edge of the first pot 310 is higher than the top edge of the second pot 320.

[0110] Generally, the upper surfaces of the first cover 210 and the second cover 220 are designed to be flush or nearly flush, that is, the first surface cover 211 of the first cover 210 and the second surface cover 221 of the second cover 220 are arranged flush. This not only makes the entire cooking utensil look more beautiful, but also makes it easier for the user to operate and clean during use. The cover height is generally the distance between the surface cover and the middle plate 400. Therefore, the cover height of the first cover 210 and the second cover 220 is relatively high, and the intersection distance between the two covers 200 is relatively long. The first cover 210 and the second cover 220 can open and close independently, and low concentricity of the rotation axis will cause interference between the two covers 200.

[0111] In the present invention, the first cover 210 and the second cover 220 are spaced apart. When the first cover 210 and the second cover 220 are covered on the pot body 100, the first cover 210 and the second cover 220 are spaced apart to form an avoidance groove 201. The groove width of the avoidance groove 201 is gradually expanded from the groove bottom to the groove mouth. The setting of the avoidance groove 201 provides the necessary space for the opening and closing of the cover 200, so that the two covers 200 will not interfere with each other on their respective movement trajectories, ensuring the smooth movement of the cover 200. The setting of the gradually expanding groove width ensures that even if there is a deviation in the movement trajectory of the cover 200, collision and interference can be avoided by gradually increasing the groove width.

[0112] In some embodiments of the present invention, the end surface of the cover 200 located in the escape groove 201 is configured as a slope 2011. Along the height direction DH of the cooking appliance, the slope 2011 slopes upward from bottom to top toward the center of the cover 200. The provision of the slope 2011 simplifies the structure of the escape groove 201, reduces the hidden area between the covers 200, makes the opening and closing process smoother and easier, and also makes the cooking appliance more convenient to clean and maintain.

[0113] In some embodiments of the present invention, the width d1 of the bottom of the avoidance groove 201 is 1-3 mm. This limited width of the bottom of the avoidance groove 201 ensures that when the lids 200 are closed, sufficient clearance is maintained between the two lids 200 to prevent direct contact and interference. This clearance allows the two lids 200 to remain relatively independent even with slight deviations, without friction or collision.

[0114] In some embodiments of the present invention, the slot width d2 of the avoidance slot 201 is ≥ 4 mm. By limiting the slot width of the avoidance slot 201, it is ensured that during the opening and closing process of the cover 200, even if there is a slight deviation in the concentricity of the rotation axis or the movement trajectory is offset, the larger slot width can provide sufficient avoidance space, ensuring that the cover 200 can pass smoothly without getting stuck or colliding.

[0115] In the present invention, properly setting the slot width helps enhance the structural stability of the avoidance slot 201. A slot width that is too narrow may cause interference and damage to components, while a slot width that is too wide may waste space and increase manufacturing costs. Therefore, the slot widths d1 and d2 fall within a relatively reasonable range, ensuring structural stability while taking into account practical usage requirements. This also makes the cooking appliance's internal structure more compact and improves space efficiency.

[0116] In the present invention, the second cover 220 cooperates with the second pot 320 to be suitable for normal pressure cooking. Figure 2 、 Figures 4 to 7 As shown, the second cover 220 is provided with a steam valve 600 to release excess steam during cooking to prevent excessive pressure in the pot, thereby being suitable for normal pressure cooking.

[0117] As can be seen from the foregoing, increasing the height of the second cover 221 of the second cover body 220 may make its central area more susceptible to deformation when exposed to heat or pressure. By adjusting the height of the steam valve 600 to be comparable to that of the second cover 221 and utilizing a portion of the steam valve 600 structure to abut against the second cover 221, additional support can be effectively provided to the second cover 221, thereby enhancing its structural stability and reducing the risk of deformation.

[0118] In some embodiments of the present invention, the second cover 220 includes a second surface cover 221, a lining cover 222, and a removable cover 223. The second surface cover 221 is located at the outermost side (i.e., the uppermost side) of the second cover 220 to form the outer shell 110 of the second cover 220. The lining cover 222 is arranged below the second surface cover 221 and connected to the second surface cover 221. For example, the lining cover 222 can be connected to the second surface cover 221 by fasteners or snaps. The lining cover 222 is mainly used to centrally install various functional components of the second cover 220 that sense and control the working status of the cooking appliance, such as sensors. The removable cover 223 is located at the innermost side (i.e., the lowermost side) of the second cover 220 and is arranged below the lining cover 222. The removable cover 223 is detachably connected to the lining cover 222, for example, by a snap connection, to facilitate cleaning and replacement. The detachable cover 223 is used to face the cooking space 101 , that is, when the second cover 220 is covered on the pot body 100 , the detachable cover 223 is located directly above the cooking space 101 .

[0119] In some embodiments of the present invention, a steam valve 600 is disposed between the second cover 221 and the lining cover 222, with at least a portion of the steam valve 600 abutting against the second cover 221 to provide support. The support provided by the steam valve 600 allows the second cover 221 to maintain greater stability during cooking, reducing problems such as poor sealing or air leaks caused by deformation. Because the steam valve 600 supports the second cover 221, the overall structural strength of the second cover 220 is enhanced, making it more durable during use and extending the lifespan of the cooking appliance.

[0120] In some embodiments of the present invention, the lining cover 222 is provided with an internal communication port 2221 for communicating with the cooking space 101. The steam valve 600 is provided with a steam chamber 610 and an air inlet 611 communicating with the steam chamber 610. The air inlet 611 is connected to the internal communication port 2221, thereby connecting the steam chamber 610 with the cooking space 101. The provision of the internal communication port 2221 and the air inlet 611 allows the steam chamber 610 to communicate with the cooking space 101, ensuring that the steam generated during cooking can smoothly enter the steam chamber 610, preventing excessive pressure in the cooking space 101 and meeting the requirements of the cooking process. It is understood that the removable cover 223 is also provided with a corresponding communication port to connect the internal communication port 2221 with the cooking space 101.

[0121] In some embodiments of the present invention, the second cover 221 is provided with an external communication port 2211 for communicating with the outside world. The steam valve 600 is also provided with an air outlet 612 that communicates with the steam chamber 610. The air outlet 612 communicates with the external communication port 2211, thereby connecting the steam chamber 610 to the outside world. The provision of the external communication port 2211 and the air outlet 612 allows the steam chamber 610 to communicate with the outside world, allowing excess steam to be discharged through the external communication port 2211, thereby preventing excessive pressure in the cooking space 101 and meeting the requirements during cooking.

[0122] In the present invention, the steam valve 600 regulates and controls the amount of steam within the cooking space 101 to ensure a moderate amount of steam, preventing the cooking effect from being affected by either excessive or insufficient steam. During the cooking process, if the pressure within the cooking space 101 becomes too high, the steam valve 600 can promptly discharge the excess steam, preventing damage to the cooking utensils or even safety accidents caused by the excessive pressure.

[0123] Optionally, the steam valve 600 is provided with a first step portion 631. The first step portion 631 abuts against the periphery of the internal communication port 2221, and the diameter of the first step portion 631 is larger than the diameter of the internal communication port 2221.

Alternatively, the second buckle 242 is provided below the second cover 221, and the second buckle position 642 is provided above the steam valve 600.

[0129] In the above embodiment, the buckle is typically positioned relative to the protruding component. Specifically, the first buckle 241 protrudes from the surface of the lining cover 222. The second buckle 242 protrudes from the surface of the second surface cover 221. The buckle body has a certain degree of elasticity and strength to ensure both secure locking and easy release. The buckle can be made of plastic, metal, or other heat-resistant materials. A locking portion is provided at the end of the buckle. The locking portion can be shaped like a hook, a bump, or a bevel, which is used to mate with the buckle position to achieve the locking function.

[0130] In the above embodiment, the buckle position is a groove, hole, or raised portion provided on the steam valve 600, which is used to mate with the buckle. Specifically, the second buckle position 642 mates with the second buckle 242, and the first buckle position 641 mates with the first buckle 241. The material strength of the buckle position matches that of the buckle to ensure the stability and durability of the connection. The buckle position is provided with a locking surface, such as a groove, flange, or bevel, that corresponds to the buckle locking portion. When the buckle and the buckle are properly mated, the locking portion and the locking surface are tightly fitted, forming a locked state.

[0131] Based on the above embodiment, the first buckle 241 cooperates with the first buckle position 641 to securely fasten the steam valve 600 to the lining cover 222. The second buckle 242 cooperates with the second buckle position 642 to securely fasten the steam valve 600 to the second cover 221. Thus, the steam valve 600 can provide stable support for the second cover 221.

[0132] In some embodiments of the present invention, the steam valve 600 is fixedly connected to the liner cover 222 via a fixing member.

[0133] Optionally, the steam valve 600 is provided with a connecting lug 650, which defines a connecting hole 651. Accordingly, the lining cover 222 defines a corresponding mounting hole. The mounting hole matches the position and size of the connecting hole 651. Fasteners (such as screws or bolts) are inserted through the connecting hole 651 on the steam valve 600 and connected to the mounting hole on the lining cover 222. The fasteners securely connect the steam valve 600 to the lining cover 222, ensuring that the steam valve 600 will not loosen or fall off.

[0134] In some embodiments of the present invention, a seal 620 is provided between the liner cover 222 and the steam valve 600. The seal 620 is respectively sealed with the internal communication port 2221 and the air inlet 611. The seal 620 helps maintain stable steam pressure and temperature within the cooking space 101, thereby ensuring consistency and controllability of the cooking process.

[0135] In some embodiments of the present invention, the seal 620 is configured as a sealing ring. The sealing ring is typically made of a wear-resistant and corrosion-resistant material, such as rubber or silicone. The sealing ring is circumferentially clamped between the liner 222 and the steam valve 600. This arrangement ensures a complete seal between the contact surfaces, effectively preventing steam leakage and significantly simplifying the installation process.

[0136] Optionally, the seal 620 is clamped between the inner wall of the internal communication port 2221 and the outer wall of the steam valve 600 .

[0137] Optionally, the seal 620 is clamped between the liner cover 222 and the first step portion 631 of the steam valve 600 .

[0138] In some embodiments of the present invention, a baffle 660 is provided in the steam valve 600. When the food in the cooking space 101 generates steam during the heating process, the steam will carry bubbles into the steam chamber 610 through the internal communication port 2221 and the air inlet 611. By providing the baffle 660, the bubbles that enter can be effectively broken. As can be seen from the above, in this embodiment, the height of the second cover 220 is relatively large. Accordingly, the height of the steam valve 600 is relatively high, and the height of the baffle 660 is relatively high. Therefore, the area of ​​the baffle 660 and the bubble breaking space can be increased. When the compressed steam from the cooking space 101 enters the steam valve 600 from the small hole, the pressure becomes smaller. Due to the large contact surface, the larger baffle 660 can improve the bubble breaking effect. After the bubbles burst, the liquid therein will be redistributed or flow back into the cooking space 101, thereby reducing the liquid content in the steam and effectively preventing the pot from overflowing when cooking rice or porridge.
