[0070] 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.
[0071] The present invention provides a cooking appliance. The dual-pot 300 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. Besides cooking rice, it can also be used for cooking porridge, soup, steaming vegetables, stewing meat, and other cooking functions.
[0072] The following will be combined Figures 1 to 10 The cooking appliance according to the present invention is described in detail.
[0073] like Figure 1-Figure 2 As shown, the cooking utensil primarily comprises a pot body 100 and a lid 200, with the lid 200 being arranged to open and close above the pot body 100. The pot body 100 has two cylindrical sections for storing the inner pot 300. The inner pot 300 is fixedly mounted in the sections, or can be freely placed in and removed from the sections, making it easy to clean. The inner pot 300 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 heating device for the inner pot 300 and a control device. The heating device can be located at the bottom of the inner pot 300 to heat the food inside. The user can control the cooking operation of the cooking utensil via the control device. Optionally, the inner pot 300 heating device can be configured as two independent heater components, with the two heaters being provided corresponding to the two inner pots 300. The two heaters can work independently or together, so that the double boiler 300 cooking appliance can achieve two or the same cooking functions.
[0074] 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.
[0075] 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 410, 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 410.
[0076] The lid 200 has a shape that basically corresponds to the pot body 100. Correspondingly, the two lids 200 are arranged corresponding to the two inner pots 300. The lid 200 is arranged on the pot body 100 in an openable and closable manner. Specifically, it is pivotally connected to the pot body 100 by a pivot shaft and can freely pivot between a closed position and an open position relative to the pot body 100 around a pivot axis where the pivot shaft is located, so as to facilitate closing and opening the pot body 100. When the lid 200 is closed on the pot body 100, it covers the inner pot 300 and forms a cooking space between it and the inner pot 300. Optionally, the two lids 200 can be opened and closed independently, or they can be arranged as an integrated unit so as to open and close simultaneously. It can be understood that when the two lids 200 cover the two inner pots 300, two independent and relatively sealed cooking spaces are formed.
[0077] 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.
[0078] The lid 200 is provided with a first sealing ring 210 and a second sealing ring 220. The first sealing ring 210 and the second sealing ring 220 can be made of, for example, rubber. The inner pot 300 includes a first inner pot 310 and a second inner pot 320. The first sealing ring 210 is provided in correspondence with the first inner pot 310 and is disposed between the lid 200 and the first inner pot 310. The second sealing ring 220 is provided in correspondence with the second inner pot 320 and is disposed between the lid 200 and the second inner pot 320. When the lid 200 is closed, two relatively sealed cooking spaces are formed.
[0079] In this solution, due to the different requirements for the sealing performance of the pot 300 for pressure cooking and normal pressure cooking, the sealing method and location of the pot 300 are different. The pressure cooking pot 300 needs to withstand higher internal pressures, so its sealing surface usually adopts a shape that can effectively resist pressure leakage. Vertical or arc-shaped sealing surfaces help to form a closer contact between the pot body and the lid, reducing the risk of leakage. The sealing requirements of the normal pressure cooking pot 300 are relatively low, and its sealing surface is generally set horizontally, achieving a seal while preventing splashing. Therefore, the pot 300 for pressure cooking and the pot 300 for normal pressure cooking cannot be directly used interchangeably. Otherwise, it may cause sealing failure, air leakage, or even damage to the pot body.
[0080] In this solution, the edge structure of the inner pot 300 is adjusted to be suitable for pressure cooking sealing and normal pressure cooking sealing.
[0081] Furthermore, the first inner pot 310 and the second inner pot 320 have the same structure. Both the first inner pot 310 and the second inner pot 320 are suitable for pressure cooking and normal pressure cooking.
[0082] Reference Figure 5-Figure 6 The inner pot 300 includes inner pot sidewalls and an inner pot rim 301 connected to the top of the inner pot sidewalls. When the lid 200 is attached to the pot body 100, at least a portion of the first sealing ring 210 is adapted to abut against the inner pot sidewalls to form a pressure seal, and at least a portion of the second sealing ring 220 is adapted to abut against the inner pot rim 301 to form a normal pressure seal.
[0083] In this embodiment, the two inner pots 300 utilize the same structure, facilitating production and maintenance while reducing manufacturing costs. The same inner pot 300 can be adapted to different cooking needs, improving the pot's utilization and adaptability. In the dual-pot 300 cooking device of this application, the two inner pots 300 can be used interchangeably, thereby reducing operational complexity.
[0084] Different sealing rings are designed to meet the different requirements of pressure cooking and normal pressure cooking, with a first sealing ring 210 and a second sealing ring 220 being provided. The first sealing ring 210 is primarily used to form a pressure seal with the sidewall of the inner pot. During pressure cooking, the tight fit of the first sealing ring 210 with the sidewall of the inner pot effectively prevents leakage of high-pressure steam, ensuring stable pressure within the pot and achieving the desired cooking effect. The second sealing ring 220 forms a normal pressure seal with the edge 301 of the inner pot. During normal pressure cooking, the tight fit of the second sealing ring 220 with the edge 301 of the inner pot is sufficient to prevent soup from overflowing from the inner pot 300, meeting the basic requirements of normal pressure cooking.
[0085] In some embodiments of the present invention, the side wall of the pot includes a straight wall portion 302 and a rounded corner portion 303 connected to the straight wall portion 302 and the edge 301 of the pot. When the lid 200 is covered on the pot body 100, the first sealing ring 210 is in close contact with at least one of the straight wall portion 302 and the rounded corner portion 303 to form a pressure seal. The side wall of the pot, through the combination of the straight wall portion 302 and the rounded corner portion 303, not only ensures the structural strength of the pot 300, but also provides a sufficient sealing contact surface. When the first sealing ring 210 is subjected to pressure, it is subjected to radial force and can easily form a close contact with either the straight wall portion 302 or the rounded corner portion 303, and is not prone to failure, so it is suitable for pressure sealing.
[0086] In some embodiments of the present invention, the fillet 303 is bent away from the center of the inner pot 300, and the radius of the fillet 303 on a plane passing through the center of the inner pot 300 is 4-6 mm. The fillet 303 of this size can effectively seal with the first sealing ring 210.
[0087] In some embodiments of the present invention, the width of the pot inner rim 301 is 2-7 mm. The width of the pot inner rim 301 directly affects the contact area and tightness between the second sealing ring 220 and the pot inner rim 300. A pot inner rim 301 of this width can ensure a stable and effective seal between the second sealing ring 220 and the pot inner rim 300.
[0088] Reference Figure 7-Figure 8 The first sealing ring 210 includes a rib 211 and a first lip 212 and a second lip 213 extending in opposite directions along the rib 211. The first lip 212 is adapted to be sealed with the inner pot 300, and the second lip 213 is adapted to be sealed with the lid 200. The rib 211 is adapted to be sealed with the inner pot 300. The first lip 212 and the second lip 213 extend in opposite directions, forming a double seal with the inner pot 300 and the lid 200, thereby enhancing the sealing performance of the first sealing ring 210. Optionally, the first sealing ring 210 can be a sealing ring with a transverse "human" cross-section. Under high pressure, the pressure will force the second lip 213 of the first sealing ring 210 to adhere tightly to the pot lid, and the first lip 212 to adhere tightly to the straight wall portion 302 and the rounded corner portion 303 of the opening of the inner pot 300. Under the influence of pressure, the greater the pressure, the greater the friction, making it less likely to be squeezed out by pressure. In the pressure relief state, the first sealing ring 210 is affected by its own structural elastic force, and the rib 211 is away from the arc surface of the pot inner 300. Only the tail edges of the first lip 212 and the second lip 213 form a line contact seal with the inner pot, so as to reduce the friction generated when the pressure cooker lid is opened and rotated.
[0089] In some embodiments of the present invention, the rib 211, the first lip 212 and the second lip 213 are all provided in a continuous circle, thereby ensuring that a continuous and uninterrupted sealing surface is formed between the first sealing ring 210, the inner pot 300 and the lid 200.
[0090] In some embodiments of the present invention, a first lip 212 extends inward and downward from the rib 211, and a second lip 213 extends inward and upward from the rib 211. The extension directions of the first lip 212 and the second lip 213 allow the sealing ring to more effectively distribute the force when under pressure, thereby enhancing the overall structural stability of the first sealing ring 210 and reducing the risk of deformation or damage caused by uneven force. The downward extension of the first lip 212 can better support the edge of the pot body 300, preventing steam from leaking from below; the upward extension of the second lip 213 can closely contact the inner surface of the lid 200, preventing steam from escaping from above.
[0091] Reference Figure 9-10 The second sealing ring 220 includes a third lip 222 and a fourth lip 223 connected at an angle. When the lid 200 is closed onto the pot body 100, the inner pot 300 abuts against the bottom of the third lip 222, bringing the third lip 222 close to the fourth lip 223. The angled connection between the third lip 222 and the fourth lip 223 increases the effective range of the second sealing ring 220, ensuring that the second sealing ring 220 maintains a good sealing performance even during long-term use. During use, due to temperature changes and thermal expansion and contraction of the cooking utensil, the angled connection between the third lip 222 and the fourth lip 223 can better adapt to these changes and maintain a tight seal.
[0092] In some embodiments of the present invention, the third lip 222 and the fourth lip 223 are both provided in a continuous circle. The continuous third lip 222 and the fourth lip 223 can ensure that a continuous and uninterrupted sealing surface is formed between the sealing ring, the inner pot 300, and the lid 200.
[0093] In some embodiments of the present invention, the third lip 222 and the fourth lip 223 have a V-shaped vertical cross-section. This V-shaped cross-section allows the second sealing ring 220 to generate a larger contact area and greater contact stress when subjected to pressure. When the inner pot 300 rests against the bottom of the third lip 222, the V-shaped cross-section allows the third lip 222 to fit more tightly against the inner pot 300, forming an effective seal and preventing steam and pressure from escaping through the gap between the second sealing ring 220 and the inner pot 300 during cooking.
[0094] In some embodiments of the present invention, the second sealing ring 220 further includes a mounting portion 221, via which the second sealing ring 220 is mounted to the cover 200. The tight fit between the mounting portion 221 and the cover 200 allows the second sealing ring 220 to be more stably secured to the cover 200, thereby maintaining better sealing performance. This stable mounting structure and structural strength prevent the second sealing ring 220 from deformation or damage during use, thereby extending its service life.
[0095] Optionally, the mounting portion 221 is provided continuously in a full circle.
[0096] In some embodiments of the present invention, the fourth lip 223 extends outward and downward from the mounting portion 221, and the third lip 222 extends inward and downward from the fourth lip 223. The arrangement of the third lip 222 and the fourth lip 223 realizes a multiple sealing mechanism. The third lip 222 acts as a first sealing barrier, first contacting the inner pot 300 and forming a preliminary seal. Subsequently, the fourth lip 223 acts as a second sealing barrier, further enhancing the sealing effect. The dual protection structure of the third lip 222 and the fourth lip 223 ensures that steam and pressure during the cooking process will not leak from the gap between the sealing ring and the inner pot 300.
