[0049] Currently, with the development of technology and the improvement of people's living standards, more and more cooking utensils appear in the kitchen to meet different cooking needs and preferences. These utensils not only improve the cooking efficiency, but also enrich the taste and nutrition of food.

[0050] There are various types of cooking utensils, including electric rice cookers, pressure cookers, electric stew pots, etc. Taking the pressure cooker as an example, the pressure cooker is a high-efficiency, energy-saving and practical kitchen tool. It applies pressure to water to make it reach a higher temperature without boiling, so as to speed up the efficiency of stewing food. The pressure cooker usually includes a pot body and a pot cover. The pot body is provided with an inner pot, and the pot cover is sealed with a sealing ring between the pot cover and the inner pot. In some pressure cookers that need to rotate the pot cover to open and close the cover, the inner pot will rotate with the pot cover when the pot cover is rotated due to the action of the sealing ring. However, some inner pots in the related art have difficulty in rotating, which causes difficulty in opening the cover and is not convenient for users to use.

[0051] Based on this, the electric pressure cooker provided in the embodiments of the present application aims to improve the problem of difficulty in opening the cover of the electric pressure cooker in the related art.

[0052] Please refer to Figures 1 to 3 The electric pressure cooker 100 of the embodiments of the present application includes a pot body assembly 100 and an upper cover 200, which is openably and closably covered on the pot body assembly 100.

[0053] The pot body 10 includes a shell 11, an outer pot 13, and an inner pot 30 (also referred to as an inner container). The shell 11 is a shell 111 structure of the pot body 10. The outer pot 13 and the inner pot 30 are both installed in the shell 11. The shell 11 provides a mounting basis for the outer pot 13, the inner pot 30, and other devices of the pot body assembly 100, and also forms a main appearance surface of the pot body assembly 100. The shell 11 can be made of metal material, or made of relatively hard plastic material, etc., which is not specifically limited here. The outer pot 13 is installed in the shell 11 and defines a heating cavity 131 with an upward opening. The inner pot 30 is used to hold food and is movably installed in the heating cavity 131. The outer pot 13 can act as a heat preservation layer to reduce heat loss. In some embodiments, the inner pot 30 can also be taken out of the heating cavity 131 for easy cleaning and replacement by the user.

[0054] The upper cover 200 is used for sealing the opening of the heating cavity 131. A sealing ring is arranged between the upper cover 200 and the pot body of the inner pot 30. In some embodiments, the upper cover 200 is provided with cover teeth and the outer pot 13 is provided with pot teeth. When the upper cover 200 is opened, the upper cover 200 needs to be rotated to make the cover teeth of the upper cover 200 disengage from the cover teeth of the outer pot 13. When the upper cover 200 is closed, the upper cover 200 needs to be rotated to make the cover teeth of the upper cover 200 engage with the pot teeth of the outer pot 13. When the upper cover 200 is rotated, the inner pot 30 will rotate together with the upper cover 200 due to the sealing ring. Figure 4 As shown in FIG. 12, the pot body assembly 100 further includes a support assembly 50 arranged in the heating cavity 131 and used for supporting the inner pot 30. That is, the inner pot 30 is supported on the support assembly 50. In the related art, the support assembly 50 is fixedly connected with the outer pot 13 or the shell 11. When the inner pot 30 rotates, the friction between the inner pot 30 and the support assembly 50 is relatively large, which makes it difficult to rotate. Under the reaction of the inner pot 30, it is difficult to rotate the upper cover 200, which leads to difficulty in opening the upper cover 200.

[0055] The support assembly 50 in the embodiments of the present application includes a support member 51. The support member 51 can rotate relative to the outer pot 13 (the pot body 10). Since the inner pot 30 is supported on the support member 51, the inner pot 30 can rotate relative to the pot body 10 through the support member 51.

[0056] In one case, when the upper cover 200 is opened or closed, the frictional resistance between the support member 51 and the inner pot 30 is smaller than the frictional resistance between the support member 51 and the pot body 10. This indicates that the frictional resistance between the support member 51 and the inner pot 30 is relatively small, and the inner pot 30 can easily rotate, so that the upper cover 200 can smoothly rotate.

[0057] In another case, when the upper cover 200 is opened or closed, the frictional resistance between the support member 51 and the inner pot 30 is greater than the frictional resistance between the support member 51 and the pot body 10. At this time, the frictional resistance between the support member 51 and the inner pot 30 is large, the support member 51 can rotate relative to the pot body 10, the inner pot 30 rotates accordingly, and the upper cover 200 can also smoothly rotate to complete the opening or closing operation.

[0058] That is, the embodiments of the present application support the inner pot 30 in the heating cavity 131 through the support assembly 50. The support assembly 50 includes a support member 51, which can rotate relative to the pot body 10 in the heating cavity 131. The inner pot 30 supported on the support member 51 can also rotate relative to the pot body 10 with the support member 51. In this way, the technical solution of the embodiments of the present application can ensure that the inner pot 30 can smoothly rotate relative to the pot body 10, avoid the situation that the inner pot 30 is stuck due to the excessive frictional resistance between the inner pot 30 and the support member 51, and thus ensure that the upper cover 200 can smoothly rotate relative to the pot body assembly 100, so as to ensure that the opening or closing operation is smoothly realized and the user experience is improved.

[0059] Please refer to Figures 2 to 4 In some embodiments, the support assembly 50 further comprises a plurality of rolling members 53, which are arranged between the support member 51 and the pot body 10 and can roll relative to the support member 51 and the pot body 10. The rolling members 53 can be made of glass material, which can not only withstand high temperature, but also has low cost and can be mass-produced. In addition, the rolling members 53 have the characteristics of insulation, i.e. non-conductive, non-magnetic, and cannot be electromagnetically induced, which can improve the safety in use and avoid affecting the normal work of the electromagnetic assembly 70 (to be mentioned later) in some pot body assemblies 100 having the electromagnetic assembly 70. In addition, the rolling members 53 can also be made of plastic, ceramic and other materials, which are not limited in the embodiments of the present application. It can be understood that the rolling members 53 can reduce the contact area between the support member 51 and the pot body 10, and because the interaction area between the rolling members 53 and the pot body 10 is small during rolling, the frictional resistance is small, so that the support member 51 is easy to rotate relative to the pot body 10, thereby ensuring that the inner pot 30 can rotate relative to the pot body 10 with the support member 51, and further ensuring that the cover opening or closing operation is smoothly performed.

[0060] It can be understood that the plurality of rolling members 53 are easy to be distributed randomly without constraints, and therefore in an embodiment, the support assembly 50 further comprises a bracket 55. The bracket 55 is arranged between the support member 51 and the pot body 10 and is used to constrain the plurality of rolling members 53. In an embodiment, the bracket 55 is provided with a plurality of mounting portions, and the plurality of rolling members 53 are rotatably mounted in the mounting portions, respectively. It can be understood that when the rolling members 53 rotate in the mounting portions, the rolling members 53 simultaneously roll relative to the surfaces of the pot body 10 and the support member 51, so that the support member 51 and the bracket 55 can rotate relative to the pot body 10. In this way, the effect of the rolling members 53 is ensured, and the rolling members 53 are limited to rotate in the mounting portions of the bracket 55, so that the positional relationship among the rolling members 53, the support member 51 and the pot body 10 is more stable, the stability of the support member 51 is improved, and the rotation of the support member 51 relative to the pot body 10 through the rolling members 53 is effectively ensured.

[0061] Optionally, the plurality of mounting portions are distributed at intervals around the central axis of the pot body assembly 100. For example, the mounting portions have centers, and the centers of the plurality of mounting portions are connected in series along the circumference of the pot body assembly 100 to form a circle with a center on the central axis of the pot body assembly 100. The plurality of mounting portions are distributed at intervals, so that the support member 51 is subjected to force more uniformly, the stability of the support member 51 is improved, and the plurality of rolling members 53 are in multi-point contact with the support member 51, thereby avoiding excessive local stress of the support member 51 and causing structural damage. Further, the intervals of the plurality of mounting portions are the same, so that the uniformity of the force applied to the support member 51 can be further improved.

[0062] As Figure 4 andFigure 5 As shown, in an optional embodiment of the present application, the rolling members 53 are spherical balls, and the mounting portion is provided with mounting grooves 551, and the rolling members 53 are rotatably arranged in the mounting grooves 551. In this embodiment, the support 55 is optionally provided in a plate shape, and a plurality of mounting grooves 551 are distributed on the support 55 at intervals, the mounting grooves 551 penetrate along the thickness direction of the support 55, and the shape of the mounting grooves 551 is adapted to the structure of the rolling members 53, which is a circular groove, so that the rolling members 53 can be rotatably accommodated in the mounting grooves 551. It can be understood that the radii of the plurality of rolling members 53 are the same, so as to ensure that the plurality of rolling members 53 can simultaneously contact the support 51 and the pot body 10, and the support 51 is more stable. Correspondingly, the sizes of the plurality of mounting grooves 551 are the same, and the inner diameter of the mounting grooves 551 is slightly larger than the radius of the rolling members 53, so as to reduce the friction between the rolling members 53 and the support 55 when the rolling members 53 rotate, and the rotation of the support 51 is more smooth.

[0063] In combination Figure 4 and Figure 6 In another embodiment of the present application, the rolling members 53 are rollers. In this embodiment, the support 55 is optionally provided in an annular shape, the rotating shaft 553 is arranged on the inner ring side of the support 55 and extends along the radial direction of the pot body assembly 100, and the roller is rotatably connected to the rotating shaft 553. It can be understood that the upper and lower sides of the roller respectively abut against the support 51 and the pot body 10, so as to rotate relative to the support 51 and the pot body 10. Of course, in addition thereto, the mounting portion of the support 55 can also be provided with a connecting hole, the rotating shaft 553 is arranged in the connecting hole and extends along the radial direction of the pot body assembly 100, and the roller is arranged in the connecting hole and rotatably connected to the rotating shaft 553.

[0064] It can be understood that the bracket 55, as an entity structure arranged between the pot body 10 and the support 51, is likely to rub against the pot body 10 and the support 51. In some other embodiments of the present application, the bracket 55 and the support 51 are an integral component, for example, in embodiments in which the support 51 and the bracket 55 are both made of plastic, the bracket 55 and the support 51 can be integrally injection molded. That is, in these embodiments, the mounting portion is directly arranged on the side of the support 51 facing the pot body 10. For example, the mounting portion forms a mounting groove 551, the opening of the mounting groove 551 faces the pot body 10, the rolling member 53 is a spherical ball, the rolling member 53 is arranged in the mounting groove 551 and partially penetrates the opening to abut against the pot body 10, so that when the rolling member 53 rolls relative to the pot body 10, the support 51 rotates relative to the pot body 10. Alternatively, in some embodiments, the support bracket and the pot body 10 are integrated, and the mounting portion is directly arranged on the side of the pot body 10 facing the support 51. For example, the mounting portion forms a rotating shaft 553 extending along the radial direction of the pot assembly 100, and the rolling member 53 is a roller rotatably connected to the rotating shaft 553. When the roller rotates, the rolling member 53 rolls relative to the support 51, and the support 51 rotates relative to the pot body 10.

[0065] Of course, the above examples are not limiting the embodiments of the present application. When the bracket 55 and the support 51 are an integral component, the mounting portion can also be arranged as the rotating shaft 553, and the rolling member 53 can be a roller; when the bracket 55 and the pot body 10 are an integral component, the mounting portion can also be arranged as the mounting groove 551, and the rolling member 53 can be a spherical ball. In embodiments in which the bracket 55 and the support 51 or the pot body 10 are an integral component, the number of parts can be reduced while ensuring that the support 51 can rotate relative to the pot body 10, thereby improving the reliability of the structure.

[0066] In the above explanation, the support 51 rotates relative to the pot body 10 by rolling the rolling member 53, but in some other embodiments of the present application, the support 51 can also slide relative to the pot body 10 to rotate. For example, in some embodiments not shown, the pot body 10 forms a sliding rail extending along the circumferential direction of the pot assembly 100, which is optionally configured to have a hook structure, and the support 51 forms a sliding groove, the sliding rail is hooked on the groove wall of the sliding groove to realize the butt joint of the support 51 and the pot body 10. The cooperation of the sliding rail and the sliding groove can reduce the direct contact area between the support 51 and the pot body 10, so that the support 51 can smoothly slide relative to the pot body 10.

[0067] In some embodiments, the electric pressure cooker 1000 can be a non-contact pressure cooker, also known as an IH (Induction Heating) pressure cooker, which uses electromagnetic heating to cook. Specifically, the induction heating pressure cooker 1000 is provided with an induction heating device 1001, which is arranged on the bottom of the pot body 10 and is connected to the power supply of the electric pressure cooker 1000. The induction heating device 1001 is configured to generate an alternating electromagnetic field when connected to the power supply, and the alternating electromagnetic field can generate an eddy current in the metal pot body 10 to heat the pot body 10. Figure 2The pot body 10 also includes an electromagnetic component 70. The shell 11 includes an outer shell 111, an outer shell cover 113, and a base 115. The electromagnetic component 70 is mounted on the base 115. The outer shell 111 is connected to the base 115. The outer shell cover 113 covers the upper end of the outer shell 111. The upper cover 200 is detachably connected to the outer shell cover 113.

[0068] In this embodiment, the electromagnetic component 70 is disposed at the bottom of the inner pot 30, the outer pot 13 is connected to the outer shell 111, and the bottom of the outer pot 13 is provided with a support portion 133 extending to the bottom of the inner pot 30. The support member 51 surrounds the outer side of the electromagnetic component 70 and is supported on the support portion 133 so that it can rotate relative to the support portion 133.

[0069] like Figure 4 As shown, in one embodiment, the support member 51 includes a bottom plate 511 and a side plate 513. The bottom plate 511 is arranged in a ring shape and is supported on the support portion 133. The side plate 513 connects to the side of the bottom plate 511 away from the electromagnetic component 70 and extends circumferentially along the support member 51. In this embodiment, the bottom plate 511 abuts against the bottom wall of the inner pot 30, and the side plate 513 abuts against the side wall of the inner pot 30. This not only enables the support member 51 to support the inner pot 30 more stably and reduce the shaking of the inner pot 30, but also separates the bottom of the inner pot 30 from the outer pot 13, preventing them from interfering with each other and affecting the rotation of the inner pot 30.

[0070] Understandably, the bottom plate 511 and the side plate 513 can be selected as an integral structure to facilitate manufacturing and improve structural integrity. Further, in one embodiment, the bottom wall and side wall of the inner pot 30 are connected by an arc transition. The support member 51 has a contoured groove on the side facing the inner pot 30, and the groove wall is correspondingly constructed as an arc. The groove wall abuts against the inner pot 30, allowing interaction between the inner pot 30 and the support member 51, improving the stability of both. Optionally, the support member 51 has multiple protrusions 515 on the side facing the inner pot 30. These protrusions 515 are spaced apart circumferentially along the support member 51 and abut against the inner pot 30. The protrusions 515 can be ribs or spherical structures protruding towards the inner pot 30, reducing the contact area between the support member 51 and the inner pot 30. This helps reduce rotational friction between the support member 51 and the inner pot 30, further enabling the inner pot 30 to rotate smoothly.

[0071] Combination Figure 2 and Figure 7The electromagnetic assembly 70 includes a coil disc 71 and a coil disc cover plate 73. The coil disc 71 is substantially disc-shaped and is connected to the housing 11. The coil disc 71 is provided with a wire wound thereon. The coil disc cover plate 73 is provided on the coil disc 71 and is partially provided in the avoiding hole 135 to shield the wire end disc, thereby improving the aesthetics and protecting the coil disc 71. In an embodiment, the support portion 133 can be a flange structure formed by inwardly bending the side structure of the outer pot 13. That is, the support portion 133 can extend in the circumferential direction of the pot body assembly 100. When viewed in the axial direction of the pot body assembly 100, the support portion 133 is annular, thereby defining the avoiding hole 135 below the inner pot 30. The electromagnetic assembly 70 is partially provided in the avoiding hole 135 to shorten the distance between the electromagnetic assembly 70 and the inner pot 30 and improve the heating effect. It can be understood that, in other embodiments, the support portion 133 of the present application can not be provided with the avoiding hole 135. Instead, the electromagnetic assembly 70 can be mounted on the lower surface of the support portion 133, for example, a boss or a groove is provided on the lower surface of the support portion 133 to limit and fix the electromagnetic assembly 70. Of course, the electromagnetic assembly 70 can also be directly fixed on the base 115 by screws or other fasteners, which is not limited in the embodiments of the present application.

[0072] In the present embodiment, the support member 51 surrounds the outside of the coil disc cover plate 73. The outer edge of the coil disc cover plate 73 is provided with a first limiting portion 731, and the side of the support member 51 close to the coil disc cover plate 73 is provided with a second limiting portion 515. The first limiting portion 731 and the second limiting portion 515 abut. Exemplarily, the first limiting portion 731 is provided with a limiting protrusion which protrudes upward relative to the rest of the coil disc cover plate 73. The second limiting portion 515 is provided with an abutting surface which abuts the outside of the limiting protrusion. Through the limiting cooperation of the first limiting portion 731 and the second limiting portion 515, the inside of the support member 51 is limited, thereby preventing the support member 51 from loosening, improving the stability of the support member 51, ensuring the normal rotation of the support member 51 relative to the support portion 133, and further ensuring the smoothness of the cover opening and closing operation.
