[0059] The electromagnetic pressure cooking equipment provided by the present application can realize the separate control of the side and the bottom of the pot body 200 in the containing cavity 120 through the arrangement of the first coil and the second coil, so that the cooking degree of the rice in each part of the pot body 200 is consistent, and the taste of the rice is improved.

[0060] ​Further preferably, the first partition 140 is arranged in the rack 100 to divide the space in the rack 100 into two cavities arranged in a vertical manner, i.e. a first cavity 150 and a second cavity 160. The accommodating cavity 120 is arranged in the first cavity 150. Two second partitions 170 are arranged between the first partition 140 and the bottom of the second cavity 160.

[0062] Preferably, in order to further improve the cooking effect and the taste of the rice, the pot body 200 is a pressure cooker. In some high-altitude areas, in order to ensure the taste of the rice and avoid the occurrence of undercooked rice, the rice is usually cooked by a pressure cooker. In the process of cooking the rice by the pressure cooker, on the one hand, the sealing between the pot body 200 and the pot cover 800 in the pressure cooker needs to be ensured to avoid air leakage. Therefore, the clamping device 600 is arranged on the mounting plane 110 to achieve the clamping and sealing between the pot body 200 and the pot cover 800. On the other hand, the pressure in the pressure cooker needs to be exhausted during the cooking process to avoid explosion due to excessive pressure in the pressure cooker. Therefore, the exhaust device 700 is arranged on the rack 100 to ensure that the pressure in the pressure cooker is maintained within a safe value range, thereby improving the safety and reliability of the pressure cooker.

[0063] It is to be noted that the number of the clamping devices 600 is multiple, and the clamping devices 600 are arranged at each corner of the mounting plane 110.

[0066] According to the prior art, there is a process error in the production process of the pot body 200 and the pot cover 800, so that the edges of the pot body 200 and the edges of the pot cover 800 cannot be absolutely flat, and when the edges of the pot body 200 and the edges of the pot cover 800 are fitted together, a part of the area between them is in a fitted state, and a gap exists in another part of the area. Therefore, in the embodiment, the adjusting structure is arranged to eliminate the gap and ensure the sealing connection between the edges of the pot body 200 and the edges of the pot cover 800.

[0070] In the embodiment, since the gap exists between the gasket 670 and the clamping plate 640, and the second connecting hole 631 on the clamping plate 640 is in the form of the long circular hole 641, the clamping plate 640 can be moved in the vertical direction or the horizontal direction, and then the roller shaft 610 can be moved in the vertical direction or the horizontal direction, so as to ensure the sealing performance of the connection between the pot body 200 and the pot cover 800.

[0071] It is further pointed out that the number of the second connecting hole 631 on the clamping plate 640 is two, and the second connecting hole 631 is arranged in the diagonal direction.

[0072] It is further pointed out that the clamping plate 640 is in the form of the U-shaped structure, the two ends of the roller shaft 610 are connected to the two sides of the open end of the clamping plate 640 respectively, and the roller shaft 610 is rotatably connected to the clamping plate 640 through the snap spring, wherein the second connecting hole 631 is arranged on the closed end of the clamping plate 640, and the closed end of the clamping plate 640 abuts against the gusset plate 630 and the output end of the clamping cylinder 620.

[0074] In the embodiment, the edge of the pot body 200 in the accommodating cavity 120 is placed on the open end of the clamping support 690, so that there is a height difference between the edge of the pot body 200 and the mounting plane 110, and enough space is left for the two roller shafts 610 when clamping the edge of the pot body 200 and the edge of the pot cover 800, and the sealing effect of the connection between the pot body 200 and the pot cover 800 can be improved by using the upper and lower clamping mode.

[0075] In addition, the roller 6100 is arranged on the open end of the clamping support 690, so that the clamping support 690 is in the rolling connection with the side wall of the pot body 200, thereby facilitating the placement and taking of the pot body 200, reducing the friction and wear between the side wall of the pot body 200 and the clamping support 690, and prolonging the service life of the pot body 200.
