Description

Technical Field

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

[0002] With the fast pace of modern life, electric pressure cookers have become widely popular due to their quick and convenient cooking method. Electric pressure cookers work by generating pressure higher than atmospheric pressure inside the pot, raising the boiling point of water, thereby shortening cooking time and locking in the nutrients in food.

[0003] Currently, electric pressure cookers are equipped with a pressure limiting valve on the lid. When the pressure inside the pot reaches the preset value, or when cooking is complete and steam needs to be released quickly, the pressure limiting valve will open to release steam and reduce the pressure inside the pot. This process is accompanied by noticeable noise.

[0004] Therefore, cooking appliances in related technologies suffer from excessive exhaust noise. Utility Model Content

[0005] This invention provides a top cover assembly and a cooking appliance to solve the problem of excessive exhaust noise in cooking appliances in the related art.

[0006] According to one aspect of the present invention, a top cover assembly is provided, comprising: an outer cover; a pressure-bearing cover rotatably disposed below the outer cover; a steam box connected to the pressure-bearing cover, the steam box having a first cavity, a second cavity, and a communication port, the first cavity and the second cavity being connected through the communication port, the second cavity having an external exhaust port; and an exhaust component disposed on the pressure-bearing cover, the exhaust component having an air inlet communicating with the cooking cavity and an exhaust port communicating with the first cavity.

[0007] The technical solution of this utility model includes an outer cover, a pressure-bearing cover, a steam box, and an exhaust vent. The pressure-bearing cover rotates relative to the outer cover, enabling the upper cover assembly to unlock and lock with the pot body. When the pressure-bearing cover rotates relative to the outer cover, the steam box rotates synchronously with the pressure-bearing cover, facilitating the entry of steam from the cooking cavity of the pot body into the steam box via the exhaust vent and its subsequent discharge to the outside. Specifically, the steam in the cooking cavity first enters the exhaust vent through its inlet, then enters the first chamber through its outlet, and finally enters the second chamber through its connecting port. The steam in the second chamber is then discharged to the outside through its exhaust port. With this structure, the steam in the cooking cavity passes sequentially through the exhaust vent, the first chamber, and the second chamber before finally being discharged to the outside, resulting in a more circuitous steam discharge path and reducing exhaust noise from the cooking appliance.

[0008] Furthermore, the steam box includes a steam base, a steam cover, and a sealing element. The steam base is connected to a pressure cover, and the steam cover is positioned above the steam base. The external vent includes a first external vent hole on the steam cover, and the sealing element is disposed between the steam base and the steam cover. By separating the steam box into a steam base and a steam cover, it is convenient to assemble components such as venting devices within the steam box. Moreover, the sealing element can seal the gap between the steam base and the steam cover, improving the cavity sealing of the steam box and allowing steam entering the steam box to flow along a predetermined path.

[0009] Furthermore, the sealing element includes a first sealing ring and a fixing bracket. The fixing bracket connects the upper end of the first sealing ring to the steam cover and the lower end of the first sealing ring to the steam seat, so as to seal the gap between the steam seat and the steam cover using the first sealing ring.

[0010] Furthermore, the first sealing ring includes a sealing cylinder, with a connecting port extending through the side wall of the sealing cylinder; the fixing frame includes a first frame, which connects the upper end of the sealing cylinder to the lower surface of the steam cover, and the lower end of the sealing cylinder to the inner wall of the steam seat; wherein, the lower surface of the steam cover, the inner side wall of the sealing cylinder, and the inner wall of the steam seat together form a first cavity, and the first cavity has good sealing performance.

[0011] Furthermore, the first sealing ring also includes a sealing plate disposed on the outer wall of the sealing cylinder, and the outer outlet also includes a second outer outlet hole disposed on the sealing plate, with the first outer outlet hole and the second outer outlet hole corresponding to each other; the fixing frame also includes a second frame body, the second frame body having a recessed platform with its opening facing the sealing plate; wherein, the lower surface of the sealing plate and the inner wall of the recessed platform together form a second cavity. Using the above structure, the fixing frame can fix the first sealing ring, and the first sealing ring can seal the gap between the steam seat and the steam cover. In addition, the fixing frame and the first sealing ring can also cooperate to divide the inner cavity of the steam box into a first cavity and a second cavity; both the fixing frame and the first sealing ring have multiple functions.

[0012] Furthermore, the upper end of the first sealing ring is provided with a first outward flange, and the edge of the fixing frame is provided with a pressing edge, which presses the first outward flange onto the steam cover, thereby connecting the upper end of the first sealing ring to the steam cover; and / or, the second frame is provided with a vertically extending cold air cylinder, which penetrates the sealing plate and allows the cold air rod to be assembled.

[0013] Furthermore, the volume of the first chamber is larger than that of the second chamber, so that the steam first enters the larger first chamber and then enters the smaller second chamber, which makes the steam discharge smoother and reduces exhaust noise; and / or, the size of the connecting port is larger than the size of the external exhaust port, which facilitates the rapid discharge of steam from the first chamber to the second chamber.

[0014] Furthermore, the venting component includes: a vent seat, disposed on the pressure-bearing cover, with an air inlet disposed on the vent seat, and an vent including multiple vent holes disposed on the vent seat; and a sealing component, movably disposed on the vent seat, having a sealing position for sealing the vent holes and an opening position for opening the vent holes. When the sealing component switches from the sealing position to the opening position, it can open the vent holes, allowing steam to escape to the outside through the vent holes, thereby achieving pressureless cooking in the cooking appliance. Compared to pressurized cooking, certain ingredients can achieve a better taste.

[0015] Furthermore, the top cover assembly also includes: a driving member, the driving end of which can drive the sealing member to move between a sealed position and an open position; a second sealing ring, wherein the steam box is provided with a clearance hole, and the second sealing ring is sealed at the clearance hole, and the second sealing ring is made of an elastic material; wherein, the exhaust seat passes through the steam box, the exhaust port is located at the part of the exhaust seat that extends into the steam box, the sealing member is located inside the steam box, the driving member is located outside the steam box, and the driving end of the driving member and the sealing member are respectively located on both sides of the second sealing ring. With the above structure, the driving member can drive the sealing member to move, thereby realizing the switching between pressurized cooking and pressureless cooking. Moreover, since the second sealing ring seals at the clearance hole, and the driving end of the driving member and the sealing member are respectively located on both sides of the second sealing ring, the clearance hole can be sealed by the second sealing ring, improving the cavity sealing of the steam box, so that the steam entering the steam box can flow along a preset path.

[0016] Furthermore, the upper cover assembly also includes a push rod seat and a push rod. The push rod seat is connected to the steam box and presses the second sealing ring onto the steam box. The push rod is movably inserted through the push rod seat, with its two ends corresponding to the second sealing ring and the drive end of the driving component, respectively. The drive end of the driving component indirectly abuts against the second sealing ring through the push rod, thereby enabling the drive end of the driving component to smoothly push the sealing component to move.

[0017] Furthermore, the second sealing ring includes a sealing body and a second outward flange. The sealing body has a structure with one end open and one end closed. The second outward flange is located at the opening of the sealing body. The push rod seat presses the second outward flange onto the steam box. The sealing body passes through the clearance hole, and one end of the push rod extends into the sealing body through the opening. With this structure, the clearance hole can be sealed using the second sealing ring. Since one end of the push rod extends into the sealing body through the opening, it also facilitates the push rod in moving the sealing element.

[0018] According to another aspect of this utility model, a cooking appliance is provided, comprising a pot body and a lid assembly, the lid assembly being disposed on the pot body, and the lid assembly being the aforementioned lid assembly. Therefore, this cooking appliance also allows steam in the cooking chamber to sequentially pass through the exhaust pipe, the first chamber, and the second chamber before finally being discharged to the outside. Because the steam discharge path is relatively tortuous, it can reduce the exhaust noise of the cooking appliance and improve the user experience. Attached Figure Description

[0046] 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.

[0047] like Figures 1 to 17 As shown, this embodiment of the present invention provides a top cover assembly, which includes an outer cover 10, a pressure-bearing cover 20, a steam box 30, and an exhaust component 40. The pressure-bearing cover 20 is rotatably disposed below the outer cover 10. The pressure-bearing cover 20 can rotate relative to the outer cover 10 to unlock and lock the top cover assembly from the pot body. The steam box 30 is connected to the pressure-bearing cover 20 and has a first cavity 31, a second cavity 32, and a connecting port 33. The first cavity 31 and the second cavity 32 are connected through the connecting port 33, and the second cavity 32 has an external exhaust port 34. The exhaust component 40 is disposed on the pressure-bearing cover 20 and has an air inlet 41 that communicates with the cooking cavity and an exhaust port 42 that communicates with the first cavity 31.

[0048] Using the top cover assembly provided in this embodiment, when the pressure cover 20 rotates relative to the outer cover 10, the steam box 30 rotates synchronously with the pressure cover 20, facilitating the entry of steam from the cooking cavity of the pot into the steam box 30 via the exhaust vent 40 and its subsequent discharge to the outside. Specifically, the steam in the cooking cavity first enters the exhaust vent 40 through the air inlet 41, then enters the first chamber 31 through the exhaust port 42, and finally enters the second chamber 32 through the connecting port 33. The steam in the second chamber 32 is then discharged to the outside through the external exhaust port 34. With this structure, the steam in the cooking cavity sequentially passes through the exhaust vent 40, the first chamber 31, and the second chamber 32 before finally being discharged to the outside. This makes the steam discharge path more circuitous, reducing exhaust noise from the cooking appliance and improving the user experience.

[0049] like Figures 1 to 7As shown, in this embodiment, the steam box 30 includes a steam seat 35, a steam cover 36, and a sealing element 37. The steam seat 35 is connected to the pressure cover 20, and the steam cover 36 covers the top of the steam seat 35. The external exhaust port 34 includes a first external exhaust hole 341 provided on the steam cover 36. The sealing element 37 is sealed between the steam seat 35 and the steam cover 36. By dividing the steam box 30 into a steam seat 35 and a steam cover 36, it is convenient to assemble components such as the exhaust element 40 inside the steam box 30. Furthermore, the sealing element 37 can seal the gap between the steam seat 35 and the steam cover 36, improving the cavity sealing of the steam box 30 and allowing the steam entering the steam box 30 to flow along a preset path.

[0050] It should be noted that the sealing element 37 is positioned between the steam seat 35 and the steam cover 36. "Sealing setting" means that the sealing element 37 can be used to seal the gap between the steam seat 35 and the steam cover 36.

[0051] In this embodiment, the steam cover 36 is connected to the outer cover 10 and covers the outer cover 10 and the steam seat 35. The steam cover 36 does not move together with the steam seat 35. In other embodiments, the steam cover 36 can be connected to the steam seat 35 and cover the top of the steam seat 35. The steam cover 36 moves together with the steam seat 35.

[0052] Furthermore, in this embodiment, by rotating the steam seat 35, the exhaust 40, and the pressure cover 20 together, the steam cover 36 is placed on the outer cover 10, thereby maximizing the volume of the steam box 30 within the limited space between the outer cover 10 and the pressure cover 20. This also helps to reduce the maximum thickness of the upper cover assembly, achieving a thinner and lighter upper cover assembly.

[0053] like Figures 5 to 7 As shown, the sealing element 37 includes a first sealing ring 371 and a fixing bracket 372. The fixing bracket 372 connects the upper end of the first sealing ring 371 to the steam cover 36 and the lower end of the first sealing ring 371 to the steam seat 35, so as to seal the gap between the steam seat 35 and the steam cover 36 using the first sealing ring 371.

[0054] like Figure 5 As shown, the first sealing ring 371 includes a sealing cylinder 3711 and a sealing plate 3712. The sealing plate 3712 is disposed on the outer wall of the sealing cylinder 3711. The connecting port 33 penetrates the side wall of the sealing cylinder 3711. The external discharge port 34 also includes a second external discharge hole 342 disposed on the sealing plate 3712. The first external discharge hole 341 and the second external discharge hole 342 are disposed opposite to each other. Steam in the second cavity 32 is discharged to the outside through the first external discharge hole 341 and the second external discharge hole 342.

[0055] like Figure 6 and Figure 7 As shown, the fixing frame 372 includes a first frame 3721 and a second frame 3722. The first frame 3721 connects the upper end of the sealing cylinder 3711 to the lower surface of the steam cover 36, and the lower end of the sealing cylinder 3711 connects to the inner wall of the steam seat 35. The second frame 3722 has a recessed platform 37221 with an opening facing the sealing plate 3712. The lower surface of the steam cover 36, the inner wall of the sealing cylinder 3711, and the inner wall of the steam seat 35 together form a first cavity 31, and the lower surface of the sealing plate 3712 and the inner wall of the recessed platform 37221 together form a second cavity 32. With this structure, the fixing frame 372 can fix the first sealing ring 371, and the first sealing ring 371 can seal the gap between the steam seat 35 and the steam cover 36.

[0056] Based on this, the fixing frame 372 and the first sealing ring 371 can also work together to divide the inner cavity of the steam box 30 into a first cavity 31 and a second cavity 32. Both the fixing frame 372 and the first sealing ring 371 have multiple functions.

[0057] like Figure 5 and Figure 7 As shown, the upper end of the first sealing ring 371 is provided with a first outward flange 37111, and the edge of the fixing bracket 372 is provided with a pressing edge 3723. The pressing edge 3723 presses the first outward flange 37111 onto the steam cover 36, thereby connecting the upper end of the first sealing ring 371 to the steam cover 36.

[0058] It should be noted that in this embodiment, the steam seat 35 has a vertical sidewall, the lower end of the sealing cylinder 3711 is located inside the vertical sidewall, and the lower end of the sealing cylinder 3711 abuts against the vertical sidewall.

[0059] Specifically, the lower end of the sealing cylinder 3711 is provided with a sealing rib 3713 that abuts against the inner wall of the steam seat 35. The lower end of the sealing cylinder 3711 abuts against the vertical side wall through the sealing rib 3713.

[0060] like Figure 6 and Figure 7 As shown, a vertically extending air cooler 37222 is provided on the second frame 3722, and the air cooler 37222 passes through the sealing plate 3712. An air cooler rod can be installed using the air cooler 37222.

[0061] In this embodiment, the volume of the first cavity 31 is larger than that of the second cavity 32. Steam first enters the larger first cavity 31 and then enters the smaller second cavity 32. The steam discharge is smoother and the exhaust noise is reduced.

[0062] Furthermore, the size of the connecting port 33 is larger than the size of the external exhaust port 34, which facilitates the rapid discharge of steam from the first cavity 31 into the second cavity 32.

[0063] like Figures 8 to 15 As shown, the exhaust component 40 includes an exhaust seat 43 and a sealing component 45. The exhaust seat 43 is disposed on the pressure-bearing cover 20, the air inlet 41 is disposed on the exhaust seat 43, the exhaust port 42 includes a plurality of exhaust holes 422 disposed on the exhaust seat 43, and the sealing component 45 is movably disposed on the exhaust seat 43. The sealing component 45 has a blocking position for blocking the exhaust holes 422 and an opening position for opening the exhaust holes 422. When the sealing component 45 switches from the blocking position to the opening position, the sealing component 45 can open the exhaust holes 422, and steam can be discharged to the outside through the exhaust holes 422, thereby realizing pressureless cooking of the cooking appliance. Compared with pressurized cooking, certain ingredients can obtain better taste.

[0064] The plurality of vent holes 422 are two or more vent holes 422. In this embodiment, the plurality of vent holes 422 are all disposed on the side wall of the vent seat 43.

[0065] In this embodiment, the exhaust component 40 also includes a pressure limiting valve 44, and the exhaust port 42 includes a top exhaust hole 421 disposed on the exhaust seat 43. The pressure limiting valve 44 is disposed at the top exhaust hole 421 in an openable and closable manner. When using a cooking appliance for pressurized cooking, the pressure inside the pot can be limited by the pressure limiting valve 44.

[0066] like Figure 1 and Figure 11 As shown, the top cover assembly also includes a drive member 50 and a second sealing ring 60. The drive end of the drive member 50 is capable of driving the sealing member 45 to move between a sealed position and an open position.

[0067] like Figure 3 As shown, the steam box 30 is provided with a clearance hole 38, and the second sealing ring 60 is sealed at the clearance hole 38. The second sealing ring 60 is made of elastic material. The exhaust seat 43 passes through the steam box 30, and the exhaust port 42 is located at the portion of the exhaust seat 43 that extends into the steam box 30. The sealing member 45 is located inside the steam box 30, and the driving member 50 is located outside the steam box 30. The driving end of the driving member 50 and the sealing member 45 are located on opposite sides of the second sealing ring 60.

[0068] With the above structure, the driving component 50 can drive the sealing component 45 to move, thereby achieving the switching between pressurized and unpressurized cooking. Furthermore, since the second sealing ring 60 seals the clearance hole 38, and the driving end of the driving component 50 and the sealing component 45 are located on opposite sides of the second sealing ring 60, the clearance hole 38 can be sealed using the second sealing ring 60, improving the cavity sealing of the steam box 30 and allowing the steam entering the steam box 30 to flow along a preset path.

[0069] The second sealing ring 60 is made of an elastic material, which means that the second sealing ring 60 can undergo elastic deformation under the push of the driving end of the driving member 50, so that the driving end of the driving member 50 can smoothly push the sealing member 45 to move.

[0070] Specifically, the second sealing ring 60 can be made of silicone.

[0071] It should be noted that the second sealing ring 60 can undergo elastic deformation under the pushing of the driving end of the driving member 50, including the driving end of the driving member 50 directly abutting against the second sealing ring 60, or the driving end of the driving member 50 indirectly abutting against the second sealing ring 60 through other components (such as push rods).

[0072] like Figures 12 to 14 As shown, in this embodiment, the upper cover assembly further includes a push rod seat 70 and a push rod 80. The push rod seat 70 is connected to the steam box 30, and the push rod seat 70 presses the second sealing ring 60 onto the steam box 30. The push rod 80 is movably inserted through the push rod seat 70, and its two ends are respectively positioned corresponding to the second sealing ring 60 and the driving end of the driving member 50. The driving end of the driving member 50 indirectly abuts against the second sealing ring 60 through the push rod 80, thereby enabling the driving end of the driving member 50 to smoothly push the sealing member 45 to move.

[0073] like Figure 1 and Figure 11 As shown, the second sealing ring 60 includes a sealing body 61 and a second outward flange 62. The sealing body 61 has a structure with one end open and the other end closed. The second outward flange 62 is disposed at the opening of the sealing body 61. The push rod seat 70 presses the second outward flange 62 onto the steam box 30. The sealing body 61 passes through the clearance hole 38, and one end of the push rod 80 extends into the sealing body 61 through the opening. With the above structure, the clearance hole 38 can be sealed by the second sealing ring 60. Since one end of the push rod 80 extends into the sealing body 61 through the opening, it is also convenient for the push rod 80 to push the sealing member 45 to move.

[0074] Among them, the push rod seat 70 presses the second outward flange 62 onto the steam box 30 through the pressure rib 71.

[0075] Another embodiment of this utility model provides a cooking appliance, which includes a pot body and a lid assembly. The lid assembly is placed on the pot body and is the same as the lid assembly provided above. Therefore, this cooking appliance also allows steam in the cooking chamber to pass sequentially through the exhaust pipe 40, the first chamber 31, and the second chamber 32 before finally being discharged to the outside. Because the steam discharge path is relatively tortuous, it can reduce the exhaust noise of the cooking appliance and improve the user experience.

[0076] Cooking appliances include, but are not limited to, electric pressure cookers and multi-functional cookers with pressure cooking functions.
