Description

Technical Field

[0001] This utility model relates to the field of pressure cooker technology, specifically to a corrosion-resistant and high-temperature-resistant stainless steel pressure cooker. Background Technology

[0002] A pressure cooker is a cooker that increases the boiling point of liquids by raising the pressure inside the pot, thus speeding up the cooking process. It is particularly suitable for cooking ingredients that are difficult to cook thoroughly, and in high-altitude areas, it effectively solves the problem of food not cooking properly. The pressure control of a pressure cooker mainly relies on the weight of the pressure relief valve on top of the lid: generally, the heavier the valve, the greater the pressure that can be achieved inside the pot.

[0003] Currently, the pressure relief valves of pressure cookers on the market are all designed with a fixed weight, which cannot be adjusted according to different needs in actual cooking scenarios. Whether it is stewing hard ingredients that require higher pressure, heating easily cooked foods that only require lower pressure, or different pressure requirements in different altitude environments, it is difficult to flexibly control the pressure inside the pot by changing the weight of the pressure relief valve. They can only operate at the same pressure value, which to a certain extent limits the flexibility and applicability of use. Therefore, a corrosion-resistant and high-temperature resistant stainless steel pressure cooker is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a corrosion-resistant and high-temperature-resistant stainless steel pressure cooker to solve the problem mentioned in the background art, where the pressure relief valve of commercially available pressure cookers has a fixed weight design, which cannot be adjusted according to different needs in actual cooking scenarios, and can only operate at the same pressure value, thus limiting the flexibility and applicability of use to a certain extent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant and high-temperature resistant stainless steel pressure cooker, comprising a pot body and a pot lid, wherein the pot lid is installed on the pot body, an exhaust pipe is installed on the pot lid, and a pressure regulating component is provided on the pot lid;

[0006] The pressure regulating assembly includes a pressure reducing exhaust hood, a mounting base, a sealing ring, a pressure seat, a spring, a scale, a pressure ring, an adjusting screw, an adjusting knob, and a sealing gasket;

[0007] The mounting base is fixedly connected to the top of the pressure relief exhaust hood. The sealing ring is embedded in the outer wall of the pressure seat. The pressure seat, pressure ring, and sealing ring are all slidably connected inside the mounting base. The scale is fixedly connected to the outer wall of the pressure ring. The bottom end of the adjusting screw is rotatably connected to the upper surface of the pressure ring. The adjusting knob is fixedly connected to the top end of the adjusting screw. The sealing gasket is fixedly connected to the lower surface of the pressure seat. The spring is located inside the mounting base.

[0008] Preferably, the two ends of the spring described above abut against the opposite surfaces of the pressure ring and the pressure seat, respectively.

[0009] Preferably, the top end of the adjusting screw described above penetrates the upper surface of the mounting base and is threadedly connected to the mounting base.

[0010] Preferably, the pressure seat described above is attached to the top of the exhaust pipe via a sealing gasket.

[0011] Preferably, the pressure-reducing exhaust hood described above is fixedly connected to the upper surface of the pot lid, and the outer side wall of the pressure-reducing exhaust hood is uniformly provided with exhaust grooves.

[0012] Preferably, the mounting base has a clearance groove on one side, the scale is slidably connected inside the clearance groove, and the outer wall of the mounting base is fixedly connected with scale lines.

[0013] Preferably, the position of the scale corresponds to the graduation line, and the pressure-reducing exhaust hood, mounting base, and exhaust pipe are all coaxially arranged.

[0014] Preferably, both the pot body and the pot lid are equipped with handles.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0016] This invention increases the pressure cooker's working pressure by rotating the adjusting screw clockwise, which pushes the pressure ring downwards. The pressure ring, with the help of a spring, pushes the pressure seat, causing it to press tightly against the exhaust pipe. Conversely, rotating the adjusting screw counterclockwise moves the pressure ring upwards, reducing the pressure on the pressure seat and lowering the pressure cooker's working pressure. Compared to existing technologies, this invention uses a pressure relief valve composed of a spring and pressure seat. By adjusting the spring's preload, the internal pressure of the pressure cooker can be adjusted to suit the needs of different ingredients. Moreover, the adjustment process is simple and efficient, improving the flexibility and adaptability of the pressure cooker. Attached Figure Description

[0026] Example

[0027] In existing technologies, the weight of pressure relief valves is fixed and cannot be adjusted according to different needs in actual cooking scenarios. Whether it is stewing hard ingredients that require higher pressure, heating easily cooked foods that only require lower pressure, or different pressure requirements in different altitude environments, it is difficult to flexibly control the pressure inside the pot by changing the weight of the pressure relief valve. It can only operate at the same pressure value, which to some extent limits the flexibility and applicability of its use.

[0028] Please see Figures 1-5This utility model provides a technical solution: a corrosion-resistant and high-temperature resistant stainless steel pressure cooker, including a pot body 33 and a pot lid 31. The pot lid 31 is installed on the pot body 33. Both the pot lid 31 and the pot body 33 are made of 316L stainless steel, which can meet the requirements of corrosion resistance and high temperature resistance of pressure cookers.

[0029] A vent pipe 32 is installed on the pot lid 31, and a pressure regulating component 101 is provided on the pot lid 31.

[0030] The pressure regulating assembly 101 includes a pressure reducing exhaust hood 11, a mounting base 12, a sealing ring 15, a pressure seat 16, a spring 17, a scale 18, a pressure ring 19, an adjusting screw 20, an adjusting knob 21, and a sealing gasket 22;

[0031] Mounting base 12 is fixedly connected to the top of pressure relief exhaust hood 11. Sealing ring 15 is embedded in the outer wall of pressure seat 16. Pressure seat 16, pressure ring 19 and sealing ring 15 are all slidably connected to the inside of mounting base 12. Sealing ring 15 and sealing gasket 22 are both made of flexible graphite material, which can withstand high temperature of 450℃.

[0032] The scale 18 is fixedly connected to the outer wall of the pressure ring 19. The bottom end of the adjusting screw 20 is rotatably connected to the upper surface of the pressure ring 19. The adjusting knob 21 is fixedly connected to the top end of the adjusting screw 20. The sealing gasket 22 is fixedly connected to the lower surface of the pressure seat 16. The top end of the adjusting screw 20 passes through the upper surface of the mounting base 12 and is threadedly connected to the mounting base 12. The pressure seat 16 is attached to the top end of the exhaust pipe 32 through the sealing gasket 22. By rotating the adjusting screw 20 clockwise, the adjusting screw 20 pushes the pressure ring 19 downward. The pressure ring 19 pushes the pressure seat 16 with the help of the spring 17, so that the pressure seat 16 presses tightly against the exhaust pipe 32, thereby increasing the pressure value of the pressure cooker. Conversely, by rotating the adjusting screw 20 counterclockwise, the pressure ring 19 moves upward, and the pressure on the pressure seat 16 decreases accordingly, thereby reducing the pressure value of the pressure cooker.

[0033] High-temperature ceramic coatings are applied to the pressure seat 16, pressure ring 19, mounting seat 12, and pressure relief exhaust hood 11 to prevent steam corrosion.

[0034] Spring 17 is located inside mounting base 12. The two ends of spring 17 abut against the opposite surfaces of pressure ring 19 and pressure seat 16, respectively. Spring 17 is made of high temperature alloy spring, such as Inconel 718 material, with a temperature resistance of >700℃.

[0035] Driven by spring 17, pressure seat 16 seals the exhaust pipe 32 of the pressure cooker, replacing the pressure relief valve in traditional technology;

[0036] Traditional pressure relief valve: Opening pressure P = Valve block weight G / Sealing surface area A;

[0037] The pressure relief valve in this design consists of spring 17 and pressure seat 16:

[0038] The opening pressure P = (spring preload F0 + gravity G) / sealing surface area A. P can be controlled by adjusting the spring preload F0.

[0039] After a 300-hour / 700℃ test, the preload of spring 17 decreased by less than 5%.

[0040] By adjusting the preload of spring 17, the internal pressure value of the pressure cooker can be adjusted to meet the needs of different ingredients. Moreover, the adjustment process is simple and efficient, improving the flexibility and adaptability of the pressure cooker.

[0041] A clearance groove 14 is provided on one side of the mounting base 12. The scale 18 is slidably connected to the inside of the clearance groove 14. A scale line 13 is fixedly connected to the outer wall of the mounting base 12. The position of the scale 18 corresponds to the scale line 13. The pressure relief exhaust hood 11, the mounting base 12 and the exhaust pipe 32 are all coaxially arranged. The scale line 13 corresponds to the pressure value when the pressure cooker is working, so that precise adjustment can be achieved.

[0042] The 13 mark needs to be calibrated using a pressure gauge before it is engraved.

[0043] In this embodiment, specifically: the pressure relief exhaust hood 11 is fixedly connected to the upper surface of the pot lid 31, and the outer side wall of the pressure relief exhaust hood 11 is evenly provided with exhaust grooves 23. Both the pot body 33 and the pot lid 31 are equipped with handles 34. When the pressure cooker is running, the steam pushes up the pressure seat 16 and then enters the pressure relief exhaust hood 11. During this process, the steam pressure is reduced and finally discharged through the exhaust grooves 23.

[0044] The working principle or structural principle of the pressure cooker is as follows: When using the pressure cooker, add ingredients to the pot body 33, then close and lock the lid 31. At this time, adjust the working pressure of the pressure cooker according to the ingredients. When it is necessary to increase the working pressure of the pressure cooker, rotate the adjusting screw 20 clockwise. The adjusting screw 20 pushes the pressure ring 19 downward. The pressure ring 19 pushes the pressure seat 16 with the help of the spring 17, so that the pressure seat 16 presses tightly against the exhaust pipe 32. Conversely, rotate the adjusting screw 20 counterclockwise. The pressure ring 19 moves upward, and the pressure on the pressure seat 16 decreases accordingly, thereby reducing the working pressure of the pressure cooker. When the working pressure of the pressure cooker reaches the rated value during operation, steam is discharged from the exhaust pipe 32 and pushes the pressure seat 16 upward. Then it enters the pressure-reducing exhaust hood 11 and is discharged through the exhaust groove 23.

[0045] In summary, this utility model uses a pressure relief valve composed of a spring 17, a pressure seat 16, and other structures. By adjusting the preload of the spring 17, the internal pressure value of the pressure cooker can be adjusted to suit the needs of different ingredients. Moreover, the adjustment process is simple and efficient, improving the flexibility and adaptability of the pressure cooker.
