[0029] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0030] A pressure cooker for fresh food, see [link / reference] Figures 1 to 10 The system includes a pot body 1, which can be filled with broth and hot steam to serve as a cooking pot, or filled with hot steam alone to serve as a steaming pot. A circulating impeller 11 is provided on the lower part of the pot body 1. A sealing element, which is a sealing ring to prevent leakage, is provided between the rotating shaft 3 of the circulating impeller 11 and the pot body 1. The circulating impeller 11 is driven by a motor. When broth and hot steam are introduced into the pot body 1 and the broth is heated, the rotation of the circulating impeller 11 achieves uniform mixing of the broth in the pot body 1, ensuring that the temperature of the broth in the pot body 1 is uniform. When cooking food, the food is cooked more evenly, ensuring that the food is cooked to the same degree.

[0031] The pot body 1 is provided with a jacket 12, and a heat medium, such as hot steam, hot water or hot oil, can be introduced into the jacket 12. By combining the hot steam introduced into the pot body 1 and the heat medium in the jacket 12, the two heating methods heat the pot body 1, which improves the heating efficiency of the pot body 1.

[0032] In this embodiment, the jacket 12 is connected to the pot body 1 through a heat medium pipeline, which is used to introduce heat medium. The heat medium pipeline includes an inlet pipe and an outlet pipe, so that the inlet pipe and outlet pipe of the heat medium pipeline form a circulation loop with the jacket 12, continuously heating the pot body 1. The heat medium is introduced into the jacket 12 inside the pot body 1 to heat the pot body 1.

[0033] To facilitate the control of the flow of the heat medium, an electric control valve is installed on the heat medium pipeline. The electric control valve controls the flow of the heat medium in the jacket 12, realizing automated control that is convenient and fast.

[0034] In addition, a soup addition pipe 13 is connected to the pot body 1. A flow control valve is installed on the soup addition pipe 13. The amount of soup to be added can be determined according to the flow control valve, and the addition of soup can be controlled to stop.

[0035] Liquid level sensors 15 are installed at different heights inside the pot body 1. When the liquid level sensor 15 detects that the soup in the pot body 1 has been lost, the electric control valve opens and soup is added through the soup addition pipe 13. The pot body 1 is also connected to an overflow pipe 16, and an electric control valve is installed on the overflow pipe 16. When the food is cooked, the foam produced can be discharged through the overflow pipe 16. The missing soup can be added at the same time, or the soup can be added and the foam can be removed at the same time.

[0036] In order to achieve uniform heating of the soup inside the pot body 1, steam heating ports 17 are respectively set at the upper, middle and lower rear sides of the pot body 1. Steam pipes are connected to the steam heating ports 17 and connected to the main steam pipe. Solenoid valves are set on the steam pipes. Steam is introduced into the pot body 1, and combined with the heating method of the jacket 12, the heating efficiency of the soup inside the pot body 1 is improved.

[0037] The bottom of the pot body 1 is provided with a drain port, and a drain pipe 18 is connected to the drain port. The drain pipe 18 is divided into two branches. One branch is used to drain the cleaning water, and the other branch is used to drain the condensate generated during soup or steam heating. Each branch is equipped with a solenoid valve.

[0038] It also includes a lid 2 that can be fitted with the pot body 1. The lid 2 is equipped with a pressure relief valve 21. When the pressure inside the pot body 1 is too high, the pressure relief valve 21 opens to release pressure and ensure the pressure inside the pot body 1. A rotating nozzle 22 is provided on the side of the lid 2 facing the pot body 1, which can spray cleaning agent in a rotating spray to cover and clean the entire inside of the pot body 1. The pipeline of the rotating nozzle 22 is in the interlayer 26 of the lid 2.

[0039] In this embodiment, the lid 2 can be flipped upward relative to the pot body 1 to open, the lid 2 can be flipped downward to cooperate with the pot body 1, the lid 2 can slide forward to engage with the pot body 1 and lock the lid 2.

[0040] The lid 2 is locked by a row of slots 191 on the left and right sides of the pot body 1. There is a specific distance between the slots 191 and the pot rim, forming a guide groove 192 that runs through the front and back. On the lower end surface of the lid 2, there are locking teeth 23 corresponding to the slots 191. The locking teeth 23 are adapted to the slots 191.

[0041] Furthermore, toothed plates 19 are connected to the rims on both sides of the pot body 1. The slots 191 are located on the upper part of the toothed plates 19. Pulleys 24 are provided on both sides of the pot lid 2. The pulleys 24 abut against the upper surface of the toothed plates 19. When the pulleys 24 slide on the toothed plates 19, the locking teeth 23 can slide in the guide grooves 192. When the locking teeth 23 are below the slots 191, the pot lid 2 is locked. The point sliding connection between the pulleys 24 and the toothed plates 19 avoids the surface sliding contact, improves the service life of the equipment, and saves time and effort.

[0042] A pneumatic sealing ring 25 is provided at the mating point between the pot body 1 and the pot lid 2. Specifically, a groove is provided on the pot lid 2 at the mating point with the pot body 1, and the pneumatic sealing ring 25 is installed in the groove. When the pot lid 2 is locked, the pneumatic sealing ring 25 is inflated to ensure the sealing between the pot body 1 and the pot lid 2, prevent air leakage, and improve heating efficiency.

[0043] In this embodiment, a rotating shaft 3 is connected to the rear end of the pot body 1. The rotating shaft 3 is a hollow rotating shaft 3. The rotating shaft 3 is connected to the rear of the pot body 1. Specifically, support plates 31 are respectively provided at the rear and side of the pot body 1. The rotating shaft 3 is rotatably connected to the support plates 31. A connector 32 is provided at the end of the rotating shaft 3 away from the pot body 1. The connector 32 is obliquely arranged and a telescopic rod 4 is connected to the connector 32. The rotating shaft 3 is driven to rotate through the telescopic rod 4, which in turn drives the pot lid 2 to rotate. In this embodiment, the telescopic rod 4 is a hydraulic cylinder. Of course, the telescopic rod 4 can also be other telescopic components, such as a pneumatic cylinder or an electric telescopic rod 4.

[0044] Furthermore, a support part 33 is connected to the rotating shaft 3. The support part 33 is horizontally arranged. The pot lid 2 is slidably connected to the support part 33. Specifically, the pot lid 2 has a sandwich 26 with reinforcing ribs inside. The pot lid 2 has an installation port, and a cover 27 is connected to the pot lid at the installation port. Guide wheels 332 are arranged on the reinforcing ribs of the pot lid 2. The guide wheels 332 are arranged in two rows, with multiple guide wheels in each row. The support part 33 has a guide rail 333, which corresponds to the guide wheels 332. The two rows of guide wheels 332 abut against the upper and lower sides of the guide rail 333, respectively. The lower end of the guide rail 333 is provided with an upward groove 3331 corresponding to the guide wheel 332. The groove 3331 has an arc-shaped part and a beveled part. The arc-shaped part is in front of the beveled part and they intersect. A plane is provided between the grooves 3331. The guide wheel 332 is slidably connected to the guide rail 333. A drive telescopic rod 34 is hinged to the support part 33. The telescopic end of the 34 is hinged to the lid 2, which can drive the lid 2 to move back and forth relative to the pot body 1. A position sensor 28 is also provided on the reinforcing rib in the interlayer 26 to detect the telescopic movement position of the drive telescopic rod 34. When the lid 2 moves forward relative to the pot body 1 to the locked position, the guide wheel 332 under the guide rail 333 gradually moves from the plane to the inclined surface, and then gradually into the arc-shaped part, playing a transition role until it completely corresponds to the groove 3331. When steaming food, an upward pressure is generated, and the groove 3331 plays a role in relieving the force, avoiding the force on the rotating shaft 3 or other components, thus reducing the service life. When the lid 2 moves backward relative to the pot body 1, the guide wheel 332 under the guide rail 333 gradually moves from the arc-shaped part to the inclined surface and then to the plane, playing a transition role. After the guide rail 333 abuts against the plane, it plays a role in limiting the left and right movement, avoiding the impact force generated by the lid 2 on the rotating shaft 3 when the lid 2 is opened.

[0045] It also includes controller 5, which is a programmable logic controller (PLC) 5, and the entire equipment is automated through controller 5.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
