Description

Technical Field

[0001] This utility model relates to the field of heat preservation and heating devices, and in particular to a steam pressure cooker with side steam inlet and outlet. Background Technology

[0002] The applicant's patent application, number 2024200313255, entitled "Basket-Type Steamer," discloses a steamer that uses steam for heating. The steam inlet valve and steam outlet valve are located on opposite sides of the steamer body. For the driver, connecting the steam heating device requires connecting to both sides of the steamer body separately, which is inconvenient.

[0003] Existing heat preservation and heating devices such as pressure cookers, steamers, or thermos flasks with steam inlet valves and steam outlet valves use existing one-way valves for their steam inlet valves and steam outlet valves. The structural fit between the one-way valve and the pot body is not ideal, resulting in poor sealing performance. Furthermore, the one-way valve port is located at the top of the pot body, preventing steam from entering the bottom of the pot body, thus resulting in unsatisfactory circulating heating effect. Utility Model Content

[0004] To address the aforementioned technical problems in the background art, this utility model provides a steam pressure cooker with side steam inlet and outlet, which allows the driver to conveniently operate the steam inlet valve, steam outlet valve, and steam generating device interface on the same side from the driver's seat, making it easy to use.

[0005] The technical solution of this utility model is as follows: This utility model is a steam pressure cooker with side steam inlet and outlet, including a pot body and a pot lid. The pot lid is set above the pot body. Its special feature is that the steam pressure cooker also includes a steam inlet valve and a steam outlet valve. The steam inlet valve and the steam outlet valve are respectively set on the barrel wall on the same side of the pot body and communicate with the inside of the pot body. A steam box is suspended inside the pot body.

[0006] Furthermore, both the steam inlet valve and the steam outlet valve are one-way steam valves. The one-way steam valve includes a valve body, a first through hole at the center of the valve body, a valve core and a plug inside the first through hole, a spring surrounding the outside of the valve core, the spring being located between the valve core and the plug, a third through hole inside the plug, and a first air guide pipe at the rear of the valve body.

[0007] Furthermore, when the one-way steam valve is a steam inlet valve, the valve core is located on the right side of the plug; when the one-way steam valve is a steam vent valve, the valve core is located on the left side of the plug.

[0008] Furthermore, a valve sleeve is provided on the outside of the valve body, and a locking cap is provided on the rear outer side of the valve sleeve. The first air guide tube passes through the locking cap and is connected to the valve body.

[0009] Furthermore, an annular retaining plate is provided on the outer side of the front end of the first air guide tube, and the annular retaining plate is located between the locking cap and the valve body.

[0010] Furthermore, a first sealing ring is provided between the annular plate and the valve body.

[0011] Furthermore, a second air guide pipe is provided at the front end of the valve body, which communicates with the first through hole.

[0012] Furthermore, the valve core has a hollow structure, and a rubber pad is installed at the bottom of the valve core.

[0013] Furthermore, a reversing valve body is provided on the front side of the valve body, a second through hole is provided inside the reversing valve body, a reversing valve core is provided inside the second through hole, a metal rod is provided on the reversing valve core, the metal rod extends out of the second through hole, and a hole communicating with the first through hole is provided on the side wall of the reversing valve body facing the valve body, and the second air guide tube is connected to the reversing valve body.

[0014] Furthermore, a second sealing ring is provided between the valve body and the reversing valve body, and a third sealing ring is provided between the reversing valve body and the valve sleeve.

[0015] The steam inlet valve and steam outlet valve of this invention are respectively located on the same side of the boiler body, which makes it convenient for the driver to operate the interface between the steam inlet valve and steam outlet valve and the steam generating device from the same side while in the driver's seat, making it easy to use.

[0016] The steam inlet valve and steam outlet valve of this utility model adopt one-way steam valves. A valve sleeve is set on the outside of the valve body, which fits tightly with the pot body, providing good sealing performance. The one-way steam valve is equipped with a second steam guide pipe, which can extend into the bottom of the pot body, allowing steam to enter the bottom of the pot body for circulating heating, resulting in good heating effect. The one-way steam valve is also equipped with a reversing valve, which switches the direction of steam in the pot body to achieve better circulating heating. The valve core of the one-way steam valve has a hollow structure, and a rubber pad is set at the bottom of the valve core. This structure reduces the weight of the valve core itself and makes the movement of the valve core in the valve body faster.

[0017] This utility model can also utilize the Chinese patent applied for by the applicant: publication number CN207229214U, entitled "A Waste Heat Extraction Device for Internal Combustion Engine Exhaust Gas", which uses the heat of recovered automobile exhaust gas to heat through the steam inlet valve.

[0024] The overall scheme of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0025] See Figure 1 The structure of this utility model includes a pot body 18, a pot lid 16, a steam inlet valve 19, and a steam vent valve 17. The pot lid 16 is located above the pot body 18. The steam inlet valve 19 and the steam vent valve 17 are respectively located on the same side of the pot body 18 and communicate with the inside of the pot body 18. A steaming box is suspended inside the pot body 18.

[0026] See Figure 2 , 3 The structure of the one-way steam valve of this utility model includes a valve body 1. A first through hole is provided at the center of the valve body 1. A valve core 11 and a plug 12 are disposed within the first through hole. A spring 3 is arranged around the outside of the valve core 11, located between the valve core 11 and the plug 12. A third through hole is provided within the plug 12. A first air guide pipe 14 is provided at the rear of the valve body 1. A valve sleeve 13 is provided on the outside of the valve body 1. A locking cap 15 is provided on the outer rear part of the valve sleeve 13. The first air guide pipe 14 passes through the locking cap 15 and communicates with the valve body 1. An annular retaining plate is provided on the outer front end of the first air guide pipe 14, located between the locking cap 15 and the valve body 1. A first sealing ring 2 is provided between the annular retaining plate and the valve body 1. A second air guide pipe 9, communicating with the first through hole, is provided at the front end of the valve body 1. The second air guide pipe 9 can extend to the bottom of the pot body. The valve core 11 has a hollow structure, and a rubber pad 10 is provided at the bottom of the valve core 11. A reversing valve body 5 is provided on the front side of valve body 1. A second through hole is provided inside the reversing valve body 5, and a reversing valve core 7 is provided inside the second through hole. A metal rod 8 is provided on the reversing valve core 7, extending outside the second through hole. A hole communicating with the first through hole is provided on the side wall of the reversing valve body 5 facing valve body 1. A second air guide pipe 9 communicates with the reversing valve body 5. A second sealing ring 4 is provided between valve body 1 and reversing valve body 5, and a third sealing ring 6 is provided between reversing valve body 5 and valve sleeve 13.

[0027] See Figure 3When the one-way steam valve of this utility model is a steam inlet valve, the valve core 11 is located on the right side of the plug 12. Its operation is as follows: Lifting the metal rod 8 allows steam to enter the first through-hole from the first air guide pipe 14. The steam pressure pushes the valve core 11 to the left. The steam passes through the gap between the valve core 11 and the first through-hole, the third through-hole in the plug 12, the hole on the side wall of the reversing valve body 5, and the second through-hole of the reversing valve body 5, entering the second air guide pipe 9. Then, through the second air guide pipe 9, the steam enters the bottom of the pot body to heat the steaming box. After steam inlet is complete, the valve core 11 returns to its initial position due to the spring force of the spring 3. Releasing the metal rod 8 causes it to fall back to its initial position. When venting steam, the metal rod 8 can be lifted, and the steam in the pot can also be discharged from the second steam pipe 9, the gap between the reversing valve core 7 and the reversing valve body 5, and the gap between the metal rod 8 and the reversing valve body 5, through the reversing valve to switch the direction of steam in the pot, so as to achieve better circulation heating.

[0028] See Figure 4 When the one-way steam valve of this utility model is a steam relief valve, the valve core 11 is located on the left side of the plug 12. Its operation is as follows: Lifting the metal rod 8 allows steam to enter from the second air guide pipe 9, passing sequentially through the second through hole of the reversing valve body 5 and the hole on the side wall of the reversing valve body 5 into the first through hole. When the discharged steam reaches a certain pressure, it squeezes the valve core 11, compressing the spring 3. The steam then passes through the gap between the valve core 11 and the first through hole, through the third through hole in the plug 12, and enters the first air guide pipe 14, exiting from the first air guide pipe 14. After steam discharge is complete, the spring force of the spring 3 returns the valve core 11 to its initial position. Releasing the metal rod 8 causes it to fall back to its initial position. When it is necessary to change the direction of steam in the pot, press down the metal rod 8. Since the reversing valve core 7 blocks the second air guide pipe 9, the steam in the pot cannot be discharged from the steam relief valve. The metal rod 8 of the steam inlet valve can be lifted, and the steam in the pot will be discharged from the reversing valve body 5 of the steam inlet valve through the second air guide pipe 9 of the steam inlet valve, the gap between the reversing valve core 7 and the reversing valve body 5, and the gap between the metal rod 8 and the reversing valve body 5. By changing the direction of steam in the pot through the reversing valve, the purpose of better circulating heating can be achieved.

[0029] In use, this invention utilizes steam heating. The steam inlet valve 19, a one-way valve, is opened. Steam flows through the steam inlet valve 19 and the second air guide pipe 9 into the bottom of the pot body, entering the bottom of the suspended steam box and the gap between the outer wall of the steam box and the inner wall of the pot body 18, thus heating or steaming. After heating or steaming is complete, the steam release valve 17 is opened. Steam enters through the second air guide pipe 9 of the steam release valve 17 and flows out through the steam release valve 17. After releasing the steam, the pot lid is opened, and the steam box is removed. The direction of the reversing valve body 5 channel at the tail of the valve body 1 is controlled by the isolation surface of the reversing valve core 7 on the metal rod 8 of the one-way valve, thus controlling the direction of steam exiting from the top / bottom of the pot body 16.

[0030] This invention can also be implemented by placing a heating pack. During heating, the heating pack is placed at the bottom of the pot body 18, water is added, and the steaming box is suspended inside the pot body 18. The pot lid 16 is then placed on top for heating. After heating is complete, the steam release valve 17 is opened, and steam enters from the second air guide pipe 9 of the steam release valve 17 and flows out through the steam release valve 17. After the steam is released, the pot lid 16 is opened, and the steaming box is removed.
