Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a cooking device for multi-stage pressure full boiling cooking. Background Art

[0002] Pressure cookers cook through high temperature and high pressure, shortening the time spent on cooking food and greatly improving cooking efficiency, so they are widely used.

[0003] The exhaust valve of the pressure cooker is a core component of the pressure cooker. Its main purpose is to ensure that the pressure inside the pressure cooker is within a specific pressure range to avoid safety accidents caused by excessive pressure in the pressure cooker. The exhaust valve is installed on the lid of the pressure cooker, and the lid is provided with an exhaust valve core for the exhaust valve to be installed. Once the air pressure in the pressure cooker is too high and is enough to lift the exhaust valve upward, the steam in the pot will be discharged from the exhaust valve core and the exhaust valve to achieve the purpose of pressure relief.

[0004] During the exhaust process of the exhaust valve, the air pressure in the pressure cooker needs to overcome the downward force F of the exhaust valve. For the most primitive pressure cooker, F downward pressure is the gravity G of the exhaust valve, and the gravity G of the exhaust valve is a constant value. Correspondingly, F downward pressure is also a constant value, and the exhaust pressure of the exhaust valve is a constant value.

[0005] However, as people's living standards improve, their requirements for material life are becoming more and more stringent, and they also have higher requirements for pressure cookers. For example, they need pressure cookers to have several different cooking pressures, so that different pressures can be used to cook different foods, or during the cooking process of the same food, pressure switching can be performed to achieve exhaust boiling effects to improve the taste of the food. At present, there are generally two types of rice cookers on the market: pressure-free cooking and pressure cooking. Pressure cooking is all single-pressure boiling cooking, and it is impossible to achieve two-stage or multi-stage full-boiling cooking. Utility Model Content

[0040] See also Figure 1-Figure 14 The utility model provides a cooking device for multi-stage pressure full boiling cooking, comprising an upper cover plate 1, a sealing component 3, a first elastic member 9, a movable pressing plate 6 and a driving mechanism. An air hole 21 and a bracket 2 are provided on the upper cover plate 1. The bracket 2 is located on the peripheral side of the air hole 21. The air hole 21 is connected to the cooking cavity inside the cooking device. The sealing component 3 and the movable pressing plate 6 are both slidably arranged on the bracket 2 up and down. The first elastic member 9 is arranged between the sealing component 3 and the movable pressing plate 6. One end of the first elastic member 9 presses the movable pressing plate 6, and the other end of the first elastic member 9 presses the sealing component 3 so that the sealing component 3 seals the air hole 21. The driving mechanism is arranged on the upper cover plate 1, and the driving mechanism is used to drive the movable pressing plate 6 to move downward.

[0041] The upper cover plate 1 covers the inner pot and forms a closed cooking cavity. The bracket 2 is arranged on the upper cover plate 1 and forms an inner cavity 22. The air hole 21 is arranged on the bottom wall of the inner cavity 22 and connects the inner cavity 22 and the cooking cavity. The sealing component 3, the first elastic member 9 and the movable pressing plate 6 are all arranged in the inner cavity 22. When cooking, the high temperature heating makes the pressure in the cooking cavity increase. When the driving mechanism is not turned on, the movable pressing plate 6 is in the first position, and the driving mechanism touches the movable pressing plate 6 lightly. The deformation of the first elastic member 9 is small, and the sealing component 3 is subjected to a small pressure. At this time, the downward force borne by the sealing component 3 is the initial pressure, and the pressure in the cooking cavity As long as the initial pressure is exceeded, the airflow in the cooking cavity will push open the sealing component 3, the sealing component 3 is separated from the air hole 21, and the gas enters the inner cavity 22 and then is discharged to the external environment, thereby realizing low-pressure boiling cooking; when the driving mechanism is turned on, the driving mechanism drives the movable pressing plate 6 to move downward, and the movable pressing plate 6 continues to squeeze the first elastic member 9, increasing its compression amount, and the squeezing force of the first elastic member 9 on the sealing component 3 increases, so that the downward force on the sealing component 3 becomes larger, and the pressure in the cooking cavity must reach a larger value to push open the sealing component 3 and separate the sealing component 3 from the air hole 21, thereby realizing high-pressure boiling cooking. By controlling the driving mechanism, full boiling cooking with at least two pressures can be realized.

[0042] Further, the top of the bracket 2 is provided with a first through hole 23, and the movable pressing plate 6 includes an abutting portion and a column provided on the abutting portion, one end of the abutting portion abuts against the bracket 2, and the other end of the abutting portion abuts against the first elastic member 9. The column passes through the first through hole 23, so that the movable pressing plate 6 can move up and down along the first through hole 23, and when the movable pressing plate 6 moves upward to the maximum displacement, the abutting portion abuts against the bracket 2 to prevent the movable pressing plate 6 from being separated from the bracket 2. When the driving mechanism is turned on, the driving mechanism presses the movable pressing plate 6, so that the movable pressing plate 6 moves downward, and the movable pressing plate 6 squeezes the first elastic member 9, so that the compression amount of the first elastic member 9 increases, and the squeezing force of the first elastic member 9 on the sealing component 3 increases, so that the sealing component 3 needs to bear the further squeezing force brought by the driving mechanism, so that the downward force borne by the sealing component 3 becomes larger, and the pressure in the cooking cavity must reach a larger value to push open the sealing component 3 so that the sealing component 3 is separated from the air hole 21, thereby realizing high-pressure boiling cooking.

[0043] Furthermore, at least one guide protrusion 24 is provided on the inner wall of the bracket 2, and at least one guide groove 311 is provided on the outer wall of the sealing assembly 3, and the guide groove 311 is used to slide up and down along the guide protrusion 24. The guide protrusion 24 cooperates with the guide groove 311 to guide the sealing assembly 3 to move up and down.

[0044] Specifically, a plurality of circumferentially distributed guide protrusions 24 are provided on the inner wall of the bracket 2, and a plurality of circumferentially distributed guide grooves 311 are provided on the outer wall of the sealing assembly 3, and each guide groove 311 is slidably connected to a guide protrusion 24. In a specific embodiment, there are three guide grooves 311 and three guide protrusions 24.

[0045] Further, the sealing assembly 3 includes a guide connector 31 and a sealing cone 32, a side wall of the sealing cone 32 is provided with an annular groove 321, the guide connector 31 is clamped in the annular groove 321, the guide groove 311 is provided on the outer wall of the guide connector 31, and the guide groove 311 passes through the bottom wall of the guide connector 31. The guide connector 31 is clamped in the sealing cone 32, so that the guide connector 31 and the sealing cone 32 can slide up and down synchronously relative to the bracket 2.

[0046] Specifically, the bottom wall of the movable pressure plate 6 is provided with an upwardly concave groove, one end of the first elastic member 9 is connected to the groove top wall of the groove, and the other end abuts against the guide connector 31. When the first elastic member 9 squeezes the guide connector 31, the sealing cone 32 also bears the same squeezing force.

[0047] Furthermore, a cover shell 11 is provided on the upper cover plate 1, and the cover shell 11 and the upper cover plate 1 are combined to form an air cavity 111, and the bracket 2 is arranged in the air cavity 111, and the air cavity 111 is connected with the cooking cavity inside the cooking device, and an exhaust port for exhausting the air cavity 111 is provided on the cover shell 11, and a through hole is provided on the cover shell 11. A first elastic connecting member 12 is provided on the cover shell 11, and the first elastic connecting member 12 is sealed on the through hole, and the driving mechanism is used to drive the first elastic connecting member 12 to elastically deform downward to drive the movable pressing plate 6 to move downward. When the driving mechanism is turned on, the driving mechanism presses the first elastic connector 12, and the first elastic connector 12 partially deforms and stretches downward, so that the driving mechanism can move downward to press the movable pressing plate 6, driving the movable pressing plate 6 to move downward together to squeeze the first elastic member 9, so that the compression of the first elastic member 9 increases, and the squeezing force of the first elastic member 9 on the sealing component 3 increases. The sealing component 3 needs to withstand the further squeezing force brought by the driving mechanism, so that the downward force borne by the sealing component 3 becomes larger, and the pressure in the cooking cavity must reach a larger value to push open the sealing component 3 so that the sealing component 3 is separated from the air hole 21, thereby realizing high-pressure boiling cooking. When the driving component 5 is closed, the first elastic member 9 drives the movable pressing plate 6 to move upward and reset under the action of its own elastic force, and at the same time resets the first elastic connector 12 and the driving mechanism.

[0048] Furthermore, the cooking device further comprises a ball valve 101 and a ball valve seat 102. The ball valve seat 102 is arranged on the upper cover plate 1 and forms a receiving cavity 103. A ball valve exhaust hole 104 is arranged at the bottom of the ball valve seat 102. The ball valve exhaust hole 104 communicates the receiving cavity 103 with the cooking cavity inside the cooking device. The ball valve 101 is arranged in the receiving cavity 103 and covers the ball valve exhaust hole 104. The receiving cavity 103 communicates with the gas cavity 111. When the pressure of the cooking cavity inside the cooking device is greater than the pressure that the ball valve 101 can withstand, the airflow of the cooking cavity pushes open the ball valve 101, enters the receiving cavity 103 from the ball valve exhaust hole 104, and then enters the gas cavity 111, and finally exhausts the gas, thereby realizing high-pressure boiling cooking.

[0049] It should be understood that when the driving mechanism is turned on to apply pressure to the sealing component 3, the downward force borne by the sealing component 3 is greater than the downward force borne by the ball valve 101. Therefore, during high-pressure cooking, the pressure in the cooking chamber is greater than the downward force borne by the ball valve 101, and the airflow in the cooking chamber will break open the ball valve 101 and exhaust from the ball valve exhaust hole 104. When the ball valve exhaust hole 104 is abnormal, such as being blocked, the pressure in the cooking chamber will continue to rise. When the pressure in the cooking chamber exceeds the downward force borne by the sealing component 3, the airflow in the cooking chamber will break open the sealing component 3, separate the sealing component 3 from the air hole 21, and exhaust is achieved. The downward force borne by the sealing component 3 when the driving mechanism is turned on is the safety pressure of the cooking device, which realizes the safety device function of the cooking device and avoids safety hazards caused by excessive pressure in the cooking chamber.

[0050] Furthermore, the upper cover plate 1 is provided with a solenoid valve assembly 8, the side wall of the housing 11 is provided with a third through hole 113, the housing 11 is provided with a second elastic connector 105, the second elastic connector 105 blocks the third through hole 113, the side wall of the ball valve seat 102 is provided with a fourth through hole for the second elastic connector 105 to pass through, and the solenoid valve assembly 8 is used to drive the second elastic connector 105 to elastically extend toward the direction of the ball valve 101 to drive the ball valve 101 to move to a side away from the solenoid valve assembly 8. When the cooking device needs to exhaust and reduce pressure, the solenoid valve assembly 8 pushes the ball valve 101 to move away from the center, and the ball valve 101 is separated from the ball valve exhaust hole 104, so that the ball valve exhaust hole 104 is opened to achieve exhaust and pressure reduction.

[0051] Furthermore, a fifth through hole is provided on the side wall of the support 2. When the sealing assembly 3 is pushed open, the gas in the cooking cavity enters the inner cavity 22 from the gas hole 21, most of the gas enters the gas cavity 111 through the fifth through hole, and some of the gas enters the gas cavity 111 from the gap between the movable pressing plate 6 and the hole wall of the first through hole 23, and is finally discharged from the exhaust hole. Specifically, the support 2 includes a valve seat and a valve cover, the guide protrusion 24 is arranged on the inner wall of the valve seat, the valve cover is sealed and connected to the valve seat, and the fifth through hole is arranged on the valve cover.

[0052] Specifically, the first elastic connector 12 is provided with an extension portion extending toward the periphery, and an annular groove is provided on the bottom wall of the extension portion. The hole wall of the through hole extends upward to form an annular plug-in block, and the annular plug-in block is plugged into the annular groove, thereby sealing the first elastic connector 12 on the through hole; the bottom of the movable rod 7 is clamped on the first elastic connector 12, so that the movable rod 7 can drive the first elastic connector 12 to extend and retract up and down.

[0053] Furthermore, the driving mechanism includes a movable rod 7, a rocker arm 4 and a driving assembly 5. A pressure plate 10 is provided on the upper cover 1. The bottom of the movable rod 7 contacts with the first elastic connecting member 12. The pressure plate 10 is arranged above the first elastic connecting member 12. A second through hole is provided on the pressure plate 10. The movable rod 7 slides up and down in the second through hole. The rocker arm 4 is rotatably connected to the upper cover 1. The driving assembly 5 is used to drive the rocker arm 4 to drive the movable rod 7 to slide downward. When the driving assembly 5 is turned on, the driving assembly 5 can drive the swing rod 4 to rotate in a clockwise direction and squeeze the movable rod 7, so that the movable rod 7 moves downward, and the bottom of the movable rod 7 presses the movable pressing plate 6, so that the movable pressing plate 6 also moves downward, and the movable pressing plate 6 squeezes the first elastic member 9, so that the compression amount of the first elastic member 9 increases, and the squeezing force of the first elastic member 9 on the sealing assembly 3 increases. The sealing assembly 3 needs to withstand the further squeezing force brought by the driving mechanism, so that the downward force borne by the sealing assembly 3 becomes larger, and the pressure in the cooking cavity must reach a larger value to push open the sealing assembly 3, so that the sealing assembly 3 is separated from the air hole 21 on the bracket 2, thereby realizing high-pressure boiling cooking. It can be understood that in this process, the first elastic connecting member 12 undergoes elastic deformation and stretches downward, so that the movable rod 7 can move downward.

[0054] Furthermore, a limit block extending outward is provided on the side wall of the movable rod 7. When the movable rod 7 moves downward to the maximum displacement, the limit block abuts against the pressure plate 10, so that the movable rod 7 cannot move further downward, thereby limiting the movable rod 7.

[0055] Furthermore, the swing arm 4 has a first rotating arm 41 and a second rotating arm 42, the first rotating arm 41 is used to rotate and squeeze the movable rod 7 to slide downward, and the second rotating arm 42 is drivingly connected to the driving assembly 5. When the driving assembly 5 is turned on, the driving assembly 5 can drive the second rotating arm 42 to rotate in a clockwise direction, so that the swing arm 4 rotates relative to the upper cover plate 1, and the first rotating arm 41 rotates downward in a clockwise direction to press the movable rod 7, so that the movable rod 7 moves downward.

[0056] Further, the driving assembly 5 is provided with a telescopic rod 51, the second rotating arm 42 is provided with at least one slide groove 422, the telescopic rod 51 is provided with at least one slider 511, and the slider 511 is slidably arranged in the slide groove 422. Specifically, the driving assembly 5 is an electromagnetic driving assembly 5, and when the electromagnet is energized, the telescopic rod 51 is attracted and contracted by the electromagnet, driving the second rotating arm 42 to rotate, so that the first rotating arm 41 rotates and squeezes the movable rod 7, so that the sealing assembly 3 is subjected to further squeezing force from the first elastic member 9, and high-pressure boiling cooking is realized; when the electromagnet is powered off, it loses its magnetism, and the swing rod 4 loses the pulling force of the telescopic rod 51. Under the action of the first elastic member 9, the swing rod 4 rotates counterclockwise, and drives the telescopic rod 51 to extend outward, and the swing rod 4 returns to the initial position.

[0057] Furthermore, two spaced-apart protrusions 421 are provided on the second rotating arm 42, and a slide groove 422 is provided on the opposite side walls of the two protrusions 421. Two sliders 511 are provided on the telescopic rod 51, and the two sliders 511 are respectively arranged on the left and right sides of the telescopic rod 51, and the two sliders 511 are respectively slidably connected to the two slide grooves 422.

[0058] Furthermore, a rotating shaft is provided on the side walls away from each other of the two protrusions 421 , two vertical plates 112 are provided on the cover shell 11 and are spaced apart from each other. The swing rod 4 is disposed between the two vertical plates 112 , and the two rotating shafts are rotatably connected to the two vertical plates 112 , respectively.

[0059] In some other embodiments, by adjusting the magnetic attraction of the electromagnetic device, the contraction distance of the telescopic rod 51 can be adjusted, thereby adjusting the swing angle of the rocker arm 4, so that the first elastic member 9 can apply different pressures to the sealing assembly 3 to achieve full boiling cooking with more than two pressure levels.

[0060] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model.
