Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, specifically to a valve body assembly, a top cover assembly, and a cooking appliance. Background Technology

[0002] Electric pressure cookers utilize the principle that the boiling point of a liquid increases under high pressure, thus accelerating the cooking process and saving cooking time.

[0003] In related technologies, electric pressure cookers include a pot body and a lid assembly mounted on the pot body. After cooking, because the pot body remains under high pressure, a pressure-limiting valve on the lid assembly is needed to release the pressurized air through the vent pipe before the lid assembly can be opened. However, existing electric pressure cookers rely solely on the pressure-limiting valve to open the vent pipe, resulting in slow venting. Furthermore, the lid assembly also has a safety valve; installing the vent pipe and safety valve requires separate mounting holes on the lid assembly, increasing manufacturing costs and making the inner surface of the lid uneven and difficult to clean. Utility Model Content

[0004] This utility model provides a valve body assembly, a top cover assembly, and a cooking appliance to solve the problem of high processing costs of electric pressure cookers in related technologies.

[0005] According to one aspect of the present invention, a valve body assembly is provided, comprising: a valve seat having a valve cavity, an inlet, and an outlet, both the inlet and the outlet communicating with the valve cavity; a valve stem movably disposed thereon, capable of opening or blocking the outlet; a connecting pipe disposed on the valve seat and sealingly fitted therewith, the connecting pipe having a through-hole communicating with the valve cavity, the connecting hole having an angle between the axis of the outlet and the extending direction of the connecting pipe; and a sealing member disposed on the connecting pipe, capable of opening or blocking the connecting hole.

[0006] The technical solution of this utility model includes a valve body assembly comprising a valve seat, a valve stem, a connecting pipe, and a sealing component. During cooking, the valve stem seals the outlet of the valve seat, and the sealing component seals the connecting hole of the connecting pipe, creating a sealed space within the cooking chamber for pressure cooking and accelerating the stewing process. After cooking, the valve stem opens the outlet of the valve seat, and the sealing component opens the connecting hole of the connecting pipe. Pressurized air from the cooking chamber enters the valve cavity through the inlet of the valve seat and exits through the outlet of the valve seat and the connecting hole of the connecting pipe. Compared to existing electric pressure cookers that only use a vent pipe for venting, this significantly speeds up the venting process. Furthermore, integrating the pressure relief valve and the vent valve reduces the number of openings on the lid, saving processing costs and resulting in a smoother inner surface for easier cleaning.

[0007] Alternatively, when there is no pressure in the cooking cavity, the valve core blocks the connecting hole. When the pressure in the cooking cavity is too high, the valve core moves to open the connecting hole, releasing the pressurized air from the cooking cavity. By integrating the safety valve and the exhaust valve, the number of openings on the lid can be reduced, saving processing costs and making the inner surface of the lid smoother and easier to clean.

[0008] Furthermore, the valve seat has an annular sidewall and a top wall, with the outlet located on the annular sidewall and its axis extending horizontally. The connecting pipe is located on the top wall and extends vertically. This design fully utilizes the valve seat's structure, integrating the outlet and connecting pipe, improving integration and facilitating manufacturing.

[0009] Furthermore, the flow area of ​​the outlet is larger than that of the connecting hole. With the above configuration, when the electric pressure cooker is cooking without pressure, exhaust can be released through the outlet, allowing for rapid exhaust.

[0010] Furthermore, the sealing element is a pressure-limiting valve located at the upper end of the connecting pipe. After cooking, the pressure-limiting valve opens the exhaust pipe, allowing pressurized air in the cooking chamber to enter the valve chamber through the valve seat inlet and exit through the connecting hole. Alternatively, the sealing element is a valve core movably located within the connecting pipe. The valve core, in conjunction with the connecting pipe, forms a safety valve. When there is no pressure in the cooking chamber, the valve core seals the connecting hole. When the pressure in the cooking chamber is too high, the valve core moves to open the connecting hole, releasing the internal pressure of the cooking chamber.

[0011] Furthermore, the valve seat also has a mounting hole that communicates with the valve cavity. A connecting pipe is inserted into the mounting hole, which has internal threads, and the outer wall of the connecting pipe has external threads. The connecting pipe is threadedly connected to the valve seat. This connection structure facilitates the installation of the valve seat and the connecting pipe.

[0012] Furthermore, the outer wall of the connecting pipe has an annular mounting groove located outside the valve seat. The valve body assembly also includes a first sealing ring disposed within the annular mounting groove, which fits against the outer wall of the valve seat. The first sealing ring seals the gap between the valve seat and the connecting pipe, resulting in a better seal in the cooking chamber during pressure cooking.

[0013] Furthermore, the outer wall of the connecting pipe is provided with an annular protrusion, and an annular mounting groove is provided on the surface of the annular protrusion facing the valve seat. This structure offers the advantage of ease of manufacturing.

[0014] Furthermore, the valve body assembly also includes a shielding cover, which is positioned above the valve seat, through which the connecting pipe passes. The shielding cover provides protection for the valve seat, thereby enhancing the overall integrity of the valve body assembly.

[0015] Furthermore, there are multiple outlets, and the valve stem is movably inserted into the valve seat laterally. The valve stem has multiple seals, and the multiple seals and multiple outlets are arranged in a one-to-one correspondence to seal the multiple outlets. By utilizing the multiple outlets, the exhaust speed can be further accelerated after cooking; and / or, the connecting pipe extends vertically to give the fluid a minimal flow path, thereby further accelerating the exhaust speed.

[0016] According to another aspect of this utility model, a top cover assembly is provided, comprising a cover body and a valve body assembly. The valve body assembly is disposed on the cover body and is the valve body assembly provided above. After cooking, the valve stem opens the outlet of the valve seat, and the sealing element opens the connecting hole of the connecting pipe. The pressurized air in the cooking chamber enters the valve chamber through the inlet of the valve seat and is discharged through the outlet of the valve seat and the connecting hole of the connecting pipe. Compared with the existing electric pressure cooker that only exhausts through the exhaust pipe, this method speeds up the exhaust process. Alternatively, when there is no pressure in the cooking chamber, the valve core seals the connecting hole. When the pressure in the cooking chamber is too high, the valve core moves to open the connecting hole, releasing the pressurized air in the cooking chamber. By integrating the safety valve and the exhaust valve, the number of openings on the cover body can be reduced, saving processing costs and making the inner surface of the cover body smoother and easier to clean.

[0017] Furthermore, the cover includes an outer cover, an inner cover, and a connector. The inner cover is detachably disposed within the outer cover and has a clearance hole. The outer wall of the valve seat of the valve body assembly has an annular boss, which passes through the clearance hole. The annular boss abuts against the upper surface of the inner cover. The connector is located below the inner cover and connected to the valve seat. By abutting the annular boss against the upper surface of the inner cover, the connector is connected to the valve seat, thereby fixing the valve seat to the inner cover and installing the valve body assembly onto the cover.

[0018] Furthermore, the top cover also includes a second sealing ring, which surrounds the outer wall of the valve seat and fits against the lower surface of the inner cover. The second sealing ring seals the gap between the valve seat and the inner cover, improving the sealing effect of the valve assembly itself and accelerating the cooking process.

[0019] According to another aspect of this utility model, a top cover is provided, comprising a cover body and a valve body assembly. The cover body includes an outer cover, an inner cover, and a steam box body. The inner cover is disposed inside the outer cover, and the steam box body is disposed on the outer cover. A cover of the valve body assembly is disposed on the steam box. The valve seat of the valve body assembly passes through the steam box, with its lower end extending out of the steam box and the inner cover. A connecting pipe of the valve body assembly extends out of the cover, and the valve stem of the valve body assembly is disposed inside the steam box. The valve body assembly is the valve body assembly provided above. By utilizing the cooperation of the steam box body and the cover, the valve seat can be accommodated, and each outlet of the valve seat is located within the cavity enclosed by the steam box body and the cover, thus avoiding excessive noise during exhaust after cooking. Alternatively, when there is no pressure in the cooking cavity, the valve core blocks the connecting hole. When the pressure in the cooking cavity is too high, the valve core moves to open the connecting hole, releasing the pressurized air in the cooking cavity. By integrating the safety valve and the exhaust valve, the number of openings on the cover can be reduced, saving processing costs and making the inner surface of the cover smoother and easier to clean.

[0020] According to another aspect of this utility model, a cooking appliance is provided, comprising a lid assembly and a pot body. The lid assembly is detachably mounted on the pot body and is the same as the lid assembly described above. After cooking, the valve stem opens the outlet of the valve seat, and the sealing element opens the connecting hole of the connecting pipe. Pressurized air in the cooking chamber enters the valve chamber through the inlet of the valve seat and is discharged through the outlet of the valve seat and the connecting hole of the connecting pipe. Compared to existing electric pressure cookers that only exhaust air through the exhaust pipe, this method accelerates the exhaust speed. Alternatively, when there is no pressure in the cooking chamber, the valve core seals the connecting hole. When the pressure in the cooking chamber is too high, the valve core moves to open the connecting hole, releasing the pressurized air from the cooking chamber. By integrating the safety valve and the exhaust valve, the number of openings on the lid body can be reduced, saving processing costs and making the inner surface of the lid body smoother and easier to clean.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0036] like Figures 1 to 4 As shown, this utility model embodiment provides a valve body assembly, which includes a valve seat 10, a valve stem 20, a connecting pipe 30, and a sealing element 40. The valve seat 10 has a valve cavity 11, an inlet 12, and an outlet 13, both of which are connected to the valve cavity 11. The valve stem 20 is movably disposed and can open or block the outlet 13. The connecting pipe 30 is disposed on the valve seat 10 and is sealed to the valve seat 10. The connecting pipe 30 has a through-hole 33 that is connected to the valve cavity 11. The axis of the outlet 13 and the extending direction of the connecting pipe 30 form an angle. The sealing element 40 is disposed on the connecting pipe 30 and can open or block the connecting hole 33.

[0037] The valve body assembly of this invention includes a valve seat 10, a valve stem 20, a connecting pipe 30, and a sealing element 40. During cooking, the valve stem 20 seals the outlet 13 of the valve seat 10, and the sealing element 40 seals the connecting hole 33 of the connecting pipe 30, creating a sealed space within the cooking chamber for pressure cooking and accelerating the stewing process. After cooking, the valve stem 20 opens the outlet 13 of the valve seat 10, and the sealing element 40 opens the connecting hole 33 of the connecting pipe 30. Pressurized air within the cooking chamber enters the valve chamber 11 through the inlet 12 of the valve seat 10 and is discharged through the outlet 13 of the valve seat 10 and the connecting hole 33 of the connecting pipe 30. Compared to existing electric pressure cookers that only exhaust air through a vent pipe, this significantly speeds up the exhaust process.

[0038] In this embodiment, the connecting pipe 30 is the existing exhaust pipe, and the sealing element 40 is the pressure limiting valve installed on the exhaust pipe. After cooking, the pressure limiting valve is used to open the exhaust pipe, and the pressurized air in the cooking chamber enters the valve chamber 11 through the inlet 12 of the valve seat 10 and is discharged through the connecting hole 33. By integrating the pressure limiting valve and the exhaust valve, the number of openings on the lid can be reduced, saving processing costs and making the inner surface of the lid smoother and easier to clean.

[0039] In another embodiment, the connecting pipe 30 is an exhaust pipe, and the sealing element 40 is a valve core movably disposed within the connecting pipe 30. The valve core, in conjunction with the connecting pipe 30, forms a safety valve. When there is no pressure in the cooking chamber, the valve core seals the connecting hole 33. When the pressure in the cooking chamber is too high, the valve core moves to open the connecting hole 33, releasing the pressurized air from the cooking chamber. By integrating the safety valve and the exhaust valve, the number of openings on the lid can be reduced, saving processing costs and making the inner surface of the lid smoother and easier to clean.

[0040] The connecting hole 33 can be configured as a variable diameter structure, with the valve core blocking the smaller diameter section. During safe venting, under the action of air pressure, the valve core moves into the larger diameter section, connecting the smaller and larger diameter sections. Alternatively, a spring can be installed, and after safe venting is completed, the spring's restoring force resets the valve core and blocks the smaller diameter section.

[0041] Alternatively, a tapered section that suddenly narrows can be provided inside the connecting hole 33, with large-diameter flow passages at both ends of the tapered section. Using air pressure, the valve core can be moved within the tapered section to open the connecting pipe 30.

[0042] Furthermore, by connecting the connecting pipe 30 to the valve seat 10, the integration of the valve body assembly can be improved, and the space occupied by the valve body assembly in the upper cover assembly can be reduced.

[0043] The valve stem 20 can move along the axis of the valve cavity or at an angle to it; for example, the movement direction of the valve stem 20 can be perpendicular to the axis of the valve cavity. Furthermore, the valve stem 20 can be disposed outside the valve seat 10 or inserted inside the valve seat 10. The specific arrangement is determined according to actual needs.

[0044] Of course, the valve body assembly provided in this embodiment can be applied not only to small household appliances, but also to other devices that require sealing and venting.

[0045] In this embodiment, the valve seat 10 has an annular sidewall and a top wall, the outlet 13 is disposed on the annular sidewall, the axis of the outlet extends horizontally, and the connecting pipe 30 is disposed on the top wall and extends vertically. This arrangement fully utilizes the structure of the valve seat 10, integrating the outlet 13 and the connecting pipe 30, improving integration and facilitating processing.

[0046] The flow area of ​​outlet 13 is larger than that of connecting hole 33. With the above configuration, when the electric pressure cooker is cooking without pressure, exhaust can be released through outlet 13 to achieve rapid exhaust during pressureless cooking.

[0047] like Figure 1 As shown, the valve seat 10 also has a mounting hole that communicates with the valve cavity 11. A connecting pipe 30 is inserted into the mounting hole, which has an internal thread. The outer wall of the connecting pipe 30 has an external thread, and the connecting pipe 30 is threadedly connected to the valve seat 10. This connection structure facilitates the installation of the valve seat 10 and the connecting pipe 30.

[0048] like Figure 1 As shown, the outer wall of the connecting pipe 30 has an annular mounting groove 31, which is located outside the valve seat 10. The valve body assembly also includes a first sealing ring disposed within the annular mounting groove 31, which fits against the outer wall of the valve seat 10. The first sealing ring can seal the gap between the valve seat 10 and the connecting pipe 30, resulting in a better sealing effect of the cooking chamber during pressure cooking.

[0049] Since the connecting pipe 30 and the valve seat 10 are connected by threads, high-pressure steam can be discharged through the gap between the threads during cooking, causing leakage. The first sealing ring can be used to seal the leak point to improve the sealing performance of the valve body assembly.

[0050] like Figure 1 As shown, the outer wall of the connecting pipe 30 is provided with an annular protrusion 32, and an annular mounting groove 31 is provided on the surface of the annular protrusion 32 facing the valve seat 10. The above structure has the advantage of being easy to process.

[0051] In related technologies, the connecting pipe 30 is vertically inserted through the upper cover and exits from the lower surface of the upper cover. To facilitate sealing, a sealing ring is provided on the lower surface of the upper cover. The sealing ring is fitted over the outside of the connecting pipe 30 and pressed tightly using a disc-shaped gasket, and then fixed using a nut located at the lower end of the connecting pipe 30. Compared to the above solution, the annular mounting groove 31 is set on the top wall of the valve seat 10, avoiding the need to install the first sealing ring and nut inside the valve seat 10, thus improving the convenience of installation operations.

[0052] In other embodiments, a disc-shaped gasket can be fitted around the outer periphery of the connecting pipe 30. The disc-shaped gasket is located outside the top wall of the valve seat 10, and an annular mounting groove 31 is formed by the disc-shaped gasket, the outer wall of the connecting pipe 30, and the top wall of the valve seat 10.

[0053] like Figure 6 As shown, the valve body assembly also includes a cover 50, which covers the valve seat 10, and the connecting pipe 30 passes through the cover 50. The cover 50 can cover the valve seat 10 to enhance the integrity of the valve body assembly.

[0054] The outer diameter of the cover 50 is larger than that of the valve seat 10.

[0055] like Figure 1 As shown, there are multiple outlets 13. The valve stem 20 is movably inserted into the valve seat 10 in the lateral direction. The valve stem 20 has multiple seals 21. The multiple seals 21 and the multiple outlets 13 are arranged one-to-one to seal the multiple outlets 13. By using the multiple outlets 13, the exhaust speed can be further accelerated after cooking.

[0056] It should be noted that multiple exports 13 include two or more exports 13.

[0057] The valve stem 20 extends in the same direction, as do the axes of the multiple outlets 13. At least one seal 21 is in sealing contact with the outer wall of the valve seat 10 and the inner wall of the valve seat 10. When the valve stem 20 blocks the outlets 13, the thrust acting on the sealing surface between the valve stem 20 and the outer wall of the valve seat 10, and the thrust acting on the sealing surface between the valve stem 20 and the inner wall of the valve seat 10, are opposite in direction and can cancel each other out. This means that when the valve stem 20 moves to open the outlets 13, it is not necessary to overcome a large force acting on the sealing surface, thus requiring only a smaller force to move the valve stem 20.

[0058] Specifically, the valve seat 10 includes a mounting base and a mounting cylinder. The valve cavity 11, the inlet 12, and the outlet 13 are all located on the mounting base. The mounting cylinder is installed through the mounting base and protrudes from the inner wall of the mounting base. The valve stem 20 passes through the inner hole of the mounting cylinder, and the mounting cylinder forms one of the outlets 13.

[0059] In this embodiment, the connecting pipe 30 extends vertically to minimize the flow path of the fluid, thereby further accelerating the exhaust speed.

[0060] like Figure 5 and Figure 6 As shown, another embodiment of this utility model provides a top cover assembly, which includes a cover body 60 and a valve body assembly. The valve body assembly is disposed on the cover body 60 and is the valve body assembly provided above. After cooking, the valve stem 20 opens the outlet 13 of the valve seat 10, and the sealing member 40 opens the connecting hole 33 of the connecting pipe 30. The pressurized air in the cooking chamber enters the valve chamber 11 through the inlet 12 of the valve seat 10 and is discharged through the outlet 13 of the valve seat 10 and the connecting hole 33 of the connecting pipe 30. Compared with the existing electric pressure cooker that only exhausts through the exhaust pipe, the exhaust speed is accelerated.

[0061] like Figure 5 As shown, the cover 60 includes an outer cover 61, an inner cover 62, and a connector. The inner cover 62 is disposed inside the outer cover 61 and has a clearance hole. The outer wall of the valve seat 10 of the valve body assembly has an annular boss 14. The valve seat 10 passes through the clearance hole, and the annular boss 14 abuts against the upper surface of the inner cover 62. The connector is located below the inner cover 62 and is connected to the valve seat 10. By abutting the annular boss 14 against the upper surface of the inner cover 62 and connecting the connector to the valve seat 10, the valve seat 10 can be fixed on the inner cover 62, thereby installing the valve body assembly on the cover 60.

[0062] In this embodiment, the connector is a connecting nut, and the outer side wall of the valve seat 10 is provided with external threads, and the connector is threadedly connected to the valve seat 10.

[0063] Specifically, the upper cover assembly also includes a second sealing ring, which surrounds the outer wall of the valve seat 10 and fits against the lower surface of the inner cover 62. The second sealing ring seals the gap between the valve seat 10 and the inner cover 62, improving the sealing effect of the valve body assembly itself and accelerating the cooking process.

[0064] The cover 60 includes a steam box 63, which is disposed on the outer cover 61. A cover 50 of the valve assembly is placed on the steam box 63. The valve seat 10 of the valve assembly passes through the steam box 63, with its lower end extending through the steam box 63 and the inner cover 62. A connecting pipe 30 of the valve assembly extends through the cover 50. The valve stem 20 of the valve assembly is disposed within the steam box 63. The steam box 63 and the cover 50 work together to accommodate the valve seat 10, placing each outlet of the valve seat 10 within the cavity formed by the steam box 63 and the cover 50. This design prevents excessive noise during exhaust after cooking.

[0065] Another embodiment of this utility model provides a cooking appliance, which includes a lid assembly and a pot body. The lid assembly is detachably mounted on the pot body and is the same as the one described above. After cooking, the valve stem 20 opens the outlet 13 of the valve seat 10, and the sealing member 40 opens the connecting hole 33 of the connecting pipe 30. The pressurized air in the cooking chamber enters the valve chamber 11 through the inlet 12 of the valve seat 10 and is discharged through the outlet 13 of the valve seat 10 and the connecting hole 33 of the connecting pipe 30. Compared with the existing electric pressure cooker that only exhausts air through the exhaust pipe, this method speeds up the exhaust process.

[0066] The cooking appliances include electric pressure cookers and multi-functional cookers with pressure cooking functions.
