Description

Technical Field

[0001] This invention relates to the field of pressure cooker technology, and in particular to a combined vacuum pressure cooker. Background Technology

[0002] Pressure cookers are popular kitchen appliances that can cook a variety of delicious foods. A typical pressure cooker consists of a pot body, a lid, and a sealing ring, and it only has a high-pressure function, not a negative pressure vacuum function. The prior invention patent CN113662423B disclosed a vacuum pressure cooker with both high-pressure and negative pressure vacuum functions, thus solving the problem that existing pressure cookers only have a high-pressure function. However, there is no combination pressure cooker that combines a pressure cooker and a steamer in the current market. Even if you want to use a pressure cooker to steam food, most existing ones simply place an external steamer on top of the pressure cooker to achieve the steaming function. There is no locking or sealing structure between the two. When the food is steamed, the steam may overturn the steamer, causing safety problems, and the leakage will result in insufficient pressure, reducing the efficiency of steaming food. Summary of the Invention

[0003] To address the above problems, this invention provides a combined vacuum pressure cooker. By adding a locking structure to the steamer body, the two are sealed together to prevent the steamer from tipping over and causing safety issues, and to speed up the steaming efficiency of food.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a combined vacuum pressure cooker, comprising:

[0005] The pot body has a pot ring on the outer periphery of its upper end, and the outer periphery of the pot ring has a plurality of outwardly protruding pot mouth teeth at intervals.

[0006] A steamer is detachably fitted onto the upper part of the pot body, and a sealing ring is provided between the pot body and the steamer. The bottom of the steamer has several air holes that communicate with the pot body. The bottom of the steamer is also rotatably equipped with a steamer ring that fits onto the upper part of the pot body. The inner side of the steamer ring has multiple ring teeth that correspond to and engage with the teeth of the pot opening. After rotating the steamer ring, the ring teeth and the teeth of the pot opening rotate relative to each other to form a locked state with the upper and lower parts corresponding to each other or an unlocked state with the upper and lower parts misaligned.

[0007] The steamer lid is detachably sealed to the top of the steamer.

[0008] Furthermore, the steamer is also equipped with a first stop valve that can slide up and down. One end of the steamer ring is equipped with a valve bracket with a round hole. When the steamer and the pot body are locked, the first stop valve and the round hole are vertically aligned, and the first stop valve moves downward and inserts into the round hole after being pressed, so as to lock the steamer ring and the steamer.

[0009] Furthermore, the steamer is provided with a first steamer handle and a second steamer handle at both ends. One end of the first steamer handle extends to the bottom of the first stop valve, and an elastic element is provided between the first stop valve and the first steamer handle to push the first stop valve upward, so that the first stop valve moves upward to unlock the steamer ring and the steamer when it is not under pressure.

[0010] Furthermore, the first check valve includes a fixed member disposed at the bottom of the steamer and a movable member that slides vertically through the middle of the fixed member. The elastic member is disposed between the movable member and the first steamer handle. The upper end of the movable member is located inside the steamer, and the lower end of the movable member is located outside the steamer and engages with the round hole. When the steamer and the pot body are in a locked state, the movable member and the round hole are vertically aligned, and the movable member moves downward and inserts into the round hole after being pressed, so as to lock the steamer ring and the steamer.

[0011] Furthermore, the lower end of the movable component is provided with a column with an outer diameter smaller than that of the movable component, and the valve frame is also provided with an arc-shaped elongated hole with one end connected to the round hole and extending circumferentially. The width of the arc-shaped elongated hole is smaller than the outer diameter of the movable component and is adapted to the outer diameter of the column. When the steamer and the pot body are in a locked state, the movable component moves downward and inserts into the round hole after being pressed to lock the steamer ring and the steamer. When the movable component is not pressed, it moves upward and disengages from the round hole under the action of the elastic element, so that the column is placed in the round hole and can rotate along the arc-shaped elongated hole.

[0012] Furthermore, the fixing component includes a limiting component passing through the bottom of the steamer and a locking component threadedly connected to the outer end of the limiting component. The limiting component has a central hole in the middle for the movable component to pass through vertically. The first check valve also includes a first sealing ring and a second sealing ring spaced apart on the outer periphery of the movable component, a third sealing ring between the limiting component and the steamer, and an air cap fitted around the outer periphery of the limiting component. The air cap is located inside the steamer, and a cavity is formed between the air cap and the limiting component for the movable component to move vertically. The air cap has several through holes communicating with the cavity. The first sealing ring and the second sealing ring are located inside and outside the central hole, respectively, so that the movable component can slide vertically within the range of the first sealing ring and the second sealing ring.

[0013] Furthermore, the inner side of the first steamer handle is provided with two rotating limiting posts located on both sides of the valve frame, and both sides of the valve frame are provided with limiting grooves that cooperate with the rotating limiting posts to stop.

[0014] Furthermore, the upper end of the pot body is provided with two symmetrically arranged handles, each handle having a raised positioning post. One end of the steamer ring is provided with a ring handle located below the second steamer handle. The bottom of both the first steamer handle and the ring handle is provided with a positioning groove to accommodate the positioning post, and one side of the positioning groove on the ring handle is open.

[0015] Furthermore, the bottom of the steamer is also provided with an inner bottom ring that fits with the pot ring. The steamer ring is rotatably fitted onto the inner bottom ring, and the sealing ring is embedded inside the inner bottom ring.

[0016] Furthermore, the combined vacuum pressure cooker also includes a lid that is detachably sealed to the upper part of the pot body, and both the lid and the steamer lid are equipped with a pressure reducing valve, a safety valve, and a second check valve.

[0017] The beneficial effects of this invention are as follows:

[0018] Firstly, by adding a steaming ring to the bottom of the steamer and locking it to the pot body, and sealing the two with a sealing ring, the two are sealed together. This ensures that the high-pressure gas generated when the pot is working can only enter the steamer through the air holes to steam the food inside. This prevents the steamer from tipping over and causing safety issues, and also speeds up the steaming process.

[0019] Secondly, the steamer ring is set at the bottom of the steamer in a rotating manner. The rotation between the steamer ring and the pot body allows the teeth of the ring to engage with the teeth of the pot to form a locking or unlocking structure. Thus, when the steamer ring is rotated to lock or unlock, neither the steamer nor the sealing ring rotates. Only the steamer ring rotates, which reduces the rotational friction between the sealing ring and the pot body and greatly reduces the frictional resistance during rotation, thus achieving the purpose of saving effort.

[0020] Third, by utilizing the cooperation between the first check valve and the valve frame, the combined vacuum pressure cooker can lock the steam pot ring and the steam pot under high pressure during use, thus preventing safety issues caused by the steam pot being rotated and opened under high pressure.

[0021] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

[0039] Example

[0040] like Figures 1 to 12 As shown in this embodiment, a combined vacuum pressure cooker includes a pot body 1, a pot lid 7 that is detachably sealed to the upper end of the pot body 1, a steamer 2 that is detachably fitted to the upper end of the pot body 1, and a steamer lid 6 that is detachably sealed to the upper end of the steamer 2. In use, the pot lid 7 and the pot body 1 can be used separately to achieve the vacuum stewing function of the pressure cooker. When the steaming function is needed, the pot lid is removed, and the steamer, steamer lid, and pot body are combined for use. The high-pressure gas from the pressure cooker can then be used for steaming within the steamer. In other words, the combination of the steamer and steamer lid is interchangeable with the pot lid 7. Of course, in a specific implementation, the shape of the upper opening of the steamer can be designed to match the shape of the upper opening of the pot body, so that the steamer lid can be fitted onto the pot lid or fitted onto the pot body, achieving a multi-purpose lid. This reduces the number of pot lids 7, simplifies the number of accessories, makes it more convenient to use, and reduces costs.

[0041] The pot body 1 has a pot ring 12 on its upper outer periphery. The pot ring 12 has a stepped cross-section. Multiple outwardly protruding pot teeth 13 are spaced around the outer periphery of the pot ring 12. These pot teeth 13 serve as a locking structure for the pot body to engage with the pot lid or steamer. A sealing ring 20 is provided between the pot body 1 and the steamer 2 or pot lid 7. After the pot lid or steamer is closed, the sealing ring contacts the pot ring, thus sealing the gap between the pot body and the pot lid or steamer. The bottom of the steamer 2 has several air holes 22 that communicate with the upper opening of the pot body 1, allowing high-pressure gas generated during use to enter the steamer. The bottom of the steamer 2 also has a rotating steamer ring 3 that fits onto the upper part of the pot body 1. The inner side of the steamer ring 3 has multiple radially protruding ring teeth 33 that correspond one-to-one with the pot teeth 13. The steamer is fitted onto the pot body, and the steamer ring 3 rotates. Then, the ring tooth 33 rotates relative to the pot mouth tooth to form a locked state corresponding to each other or an unlocked state with the upper and lower parts misaligned. That is, during the process of the steamer being fitted into the pot body, the ring tooth 33 first passes downward through the gap between two adjacent pot mouth teeth 13, and then the steamer ring is rotated, causing the ring tooth 33 to rotate to the bottom of the pot mouth tooth 13, forming a nested locked state corresponding to each other. After the steamer ring is rotated in the opposite direction, the ring tooth 33 leaves the pot mouth tooth 13, forming an unlocked state with the upper and lower parts misaligned, so that the steamer can be opened outward and removed. It can be understood that the locking structure between the lid and the pot body can be similar to the locking structure between the steamer and the pot body, that is, a cover ring with the same shape as the steamer ring 3 is provided on the outer circumference of the lid, and the relative rotation between the cover ring and the pot body is used to achieve the locking or unlocking between the lid and the pot body.

[0042] In the above-mentioned method, firstly, a steaming ring is added to the bottom of the steamer to lock with the pot body, and a sealing ring is used to seal the two, so that the high-pressure gas generated when the pot is working can only enter the steamer through the air vents to cook the food inside. This prevents the steamer from tipping over and causing safety issues, and also speeds up the cooking process. Secondly, the steaming ring is mounted on the bottom of the steamer in a rotating manner. The rotation between the steaming ring and the pot body allows the teeth of the ring to engage with the teeth of the pot to form a locking or unlocking structure. Thus, when the steaming ring is rotated to lock or unlock, neither the steamer nor the sealing ring rotates; only the steaming ring rotates. This reduces the rotational friction between the sealing ring and the pot body, greatly reducing frictional resistance during rotation and achieving the purpose of saving effort.

[0043] Preferably, the steamer 2 is also equipped with a first check valve 5 that can slide up and down. One end of the steamer ring 3 is equipped with a valve bracket 41, and the valve bracket 41 is equipped with a round hole 42. When the steamer 2 and the pot body 1 are locked, the first check valve 5 and the round hole 42 are exactly aligned vertically. That is, in the locked state, the first check valve can enter the round hole 42 during the up and down sliding process, so that the first check valve 5 moves downward and inserts into the round hole after being pressurized, thereby locking the steamer ring 3 and the steamer 2. This achieves the locking of the steamer ring 3 and the steamer 2 under high pressure when the steamer is in use. The steamer ring 3 and the steamer 2 cannot rotate, avoiding the safety problem caused by the steamer being rotated and opened under high pressure.

[0044] Preferably, the steamer 2 has a first steamer handle 21 and a second steamer handle 23 at its two ends. One end of the first steamer handle 21 extends below the first check valve 5, and an elastic element 60 is provided between the first check valve 5 and the first steamer handle 21 to push the first check valve 5 upward. This allows the first check valve 5 to move upward under the elastic force applied by the elastic element when it is not in operation and is under normal pressure, thus unlocking the steamer ring 3 and the steamer 2. When the steamer is in operation, the high-pressure gas entering the steamer will apply a downward force to the first check valve, thereby overcoming the elastic force of the elastic element and moving it downward to lock the steamer ring 3 and the steamer 2. It is understood that, in order to facilitate the function of the elastic element, the elastic element is preferably a spring.

[0045] Preferably, the first check valve 5 includes a fixed member located at the bottom of the steamer 2 and a movable member 61 that slides vertically through the middle of the fixed member. An elastic member 60 is located between the movable member 61 and the first steamer handle 21. The upper end of the movable member 61 is located inside the steamer 2 to receive the pressure applied to it inside the steamer. The lower end of the movable member 61 is located outside the steamer 2 and engages with the round hole 42. When the steamer 2 and the pot body 1 are locked, the movable member 61 and the round hole 42 correspond vertically. After being subjected to pressure from the high-pressure gas in the steamer, the movable member 61 moves downward and inserts into the round hole 42 to lock the steamer ring 3 and the steamer 2.

[0046] Preferably, the fixing component includes a limiting member 51 passing through the bottom of the steamer 2 and a locking member 50 threadedly connected to the outer end of the limiting member 51. The threaded connection facilitates the installation of the fixing component onto the steamer. The limiting member 51 has a central hole 52 in the middle for the movable member 61 to pass through vertically. To ensure pressure on the movable member, a seal must be maintained between the movable member and the fixing member during vertical sliding to prevent insufficient pressure due to air leakage. The first check valve 5 also includes a first sealing ring 64 and a second sealing ring 65 spaced apart on the outer periphery of the movable member 61, a third sealing ring 53 located between the limiting member 51 and the steamer 2, and an air cap 54 fitted around the outer periphery of the limiting member 51. The third sealing ring 53 seals the gap between the limiting member and the steamer. The air cap 54 is located inside the steamer 2, and a cavity 55 is formed between the air cap 54 and the limiting member 51 for the movable member 61 to move vertically. The air cap 54 has several through holes 56 communicating with the cavity 55, thereby allowing the movable member 61 to move vertically. High-pressure gas in the steamer enters the cavity and applies downward pressure to the moving part. The first sealing ring 64 and the second sealing ring 65 are located inside and outside the central hole 52, respectively, so that the moving part 61 can slide up and down within the range of the first sealing ring and the second sealing ring. The outer diameter of the first sealing ring 64 and the second sealing ring 65 is larger than the outer diameter of the central hole 52. They are used to seal the inner and outer orifices of the central hole, respectively, under pressure or non-pressure conditions of the first check valve 5. That is, when the steamer is under high pressure, the moving part moves downward under the internal high pressure, so that the first sealing ring abuts against the inner side of the bottom of the steamer to seal the inner orifice of the central hole. The lower end of the moving part is inserted into the round hole to lock it. When the steamer is under normal pressure or vacuum, the moving part moves upward under the elastic force of the elastic element. The second sealing ring abuts against the outer surface of the bottom of the steamer to seal the outer orifice of the central hole. The lower end of the moving part moves upward and disengages from the round hole, unlocking the steamer ring and the steamer.

[0047] Preferably, the lower end of the movable part 61 is integrally formed with a column 62 with an outer diameter smaller than its own. The valve frame 41 is also provided with an arc-shaped elongated hole 43 with one end connected to the round hole 42 and extending circumferentially. The width of the arc-shaped elongated hole 43 is smaller than the outer diameter of the movable part 61 and is adapted to the outer diameter of the column 62. That is, the movable part cannot rotate into the arc-shaped elongated hole 43, but the column 62 can. When the steamer 2 and the pot body 1 are in a locked state, the column 62 is placed in the round hole. When the movable part 61 is subjected to high pressure, it moves downward and inserts into the round hole 42. Because the movable part cannot rotate into the arc-shaped elongated hole, the steamer ring 3 and the steamer 2 are locked. However, when the steamer returns to the normal pressure state, the movable part is not subjected to the pressure of the high-pressure gas and moves upward and disengages from the round hole under the action of the elastic element. At this time, the column is placed in the round hole and can rotate along the arc-shaped elongated hole. Thus, the steamer ring can be rotated within the range of the arc-shaped elongated hole to rotate and unlock the steamer and the pot body.

[0048] Preferably, the inner side of the first steamer handle 21 is provided with two rotating limiting posts 24 respectively located on both sides of the valve frame 41. Both sides of the valve frame 41 are provided with limiting grooves 44 that cooperate with the rotating limiting posts 24 to stop. This stopping structure located on both sides is used to limit the rotation angle of the steamer ring, preventing the rotation from exceeding the stroke and causing damage to the first stop valve. It can also prevent the steamer ring from rotating arbitrarily relative to the steamer, keeping the position of the steamer ring stable. This facilitates the locking operation when the steamer lid is closed on the pot body next time, and prevents the position change caused by the random rotation of the steamer ring from affecting the locking operation between the steamer and the pot body.

[0049] Preferably, the upper end of the pot body 1 is provided with two symmetrically arranged handles 11, and the handles 11 are provided with protruding positioning posts 15. One end of the steam pot ring 3 is provided with a ring handle 4 located below the second steam pot handle 23. The ring handle 4 facilitates the control of the rotation of the steam pot ring. The bottom of the first steam pot handle 21 and the ring handle 4 are provided with positioning grooves 25 to accommodate the positioning posts 15, so as to realize the positioning assembly between the steam pot and the pot body. After the steam pot and the pot body are assembled, they cannot rotate relative to each other, so as to avoid the problem of the steam pot being opened due to accidental rotation during use. The positioning groove on the ring handle 4 is open on one side, so that the ring handle can be rotated to unlock and leave the positioning post or rotated to lock and enter the positioning groove.

[0050] Preferably, the bottom of the steamer 2 is also provided with a bottom inner ring 31 that is fitted together with the pot ring 12. The steamer ring 3 is rotated and fitted onto the bottom inner ring 31, and the sealing ring 20 is embedded in the inner side of the bottom inner ring 31.

[0051] Preferably, both the pot lid 7 and the steamer lid 6 are equipped with a pressure reducing valve 71, a safety valve 72, and a second check valve 73.

[0052] The above-described specific embodiments are merely preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; all equivalent modifications made in accordance with the scope of protection of the claims of the present invention are covered by the scope of protection of the claims of the present invention.
