[0002] When cooking food in an electric pressure cooker, the inner cavity of the electric pressure cooker has high pressure and temperature, which can speed up the cooking of food and make the food softer and more glutinous.
[0003] In the related art, after cooking is completed, the electric pressure cooker needs to be vented. An exhaust button, an exhaust lever and a pressure limiting valve are arranged on the upper cover. By pressing the exhaust button, the exhaust button uses the exhaust push rod to push up the pressure limiting valve to achieve rapid exhaust.
[0004] However, with the above structure, the user needs to press the exhaust button for a long time, and the cooking appliance has the problem of low exhaust efficiency. Utility Model Content
[0005] The utility model provides an upper cover and a cooking utensil having the same, so as to solve the problem of low exhaust efficiency of the cooking utensil in the related art.
[0006] According to one aspect of the utility model, an upper cover is provided, which includes: a cover body, provided with a first exhaust pipe and a second exhaust pipe; a first pressure-limiting valve and a second pressure-limiting valve, the first pressure-limiting valve being arranged on the first exhaust pipe, and the second pressure-limiting valve being arranged on the second exhaust pipe; a lifting member, movably arranged on the cover body, the lifting member having a separation state separated from the first pressure-limiting valve and the second pressure-limiting valve and a lifting state capable of lifting the first pressure-limiting valve and / or the second pressure-limiting valve.
[0007] Applying the technical solution of the utility model, the upper cover includes a cover body, a first pressure-limiting valve, a second pressure-limiting valve and a lifting member. Since the lifting member has a separation state separated from the first pressure-limiting valve and the second pressure-limiting valve and a lifting state capable of lifting the first pressure-limiting valve and / or the second pressure-limiting valve. In other words, the lifting member can lift the first pressure-limiting valve, or lift the second pressure-limiting valve, or lift the first pressure-limiting valve and the second pressure-limiting valve at the same time. When the cooking utensil needs to be exhausted, according to the exhaust demand, if the exhaust volume demand is not very large, the lifting member can be used to lift the first pressure-limiting valve or the second pressure-limiting valve for exhaust. If the exhaust volume demand is relatively large, the lifting member can be used to lift the first pressure-limiting valve and the second pressure-limiting valve at the same time, so that the exhaust of the cooking utensil is more flexible. In addition, since the lifting member can lift the first pressure-limiting valve and the second pressure-limiting valve at the same time, the exhaust efficiency can also be improved.
[0008] Further, the lifting member includes a rotating rod movably arranged in the vertical direction, and the rotating rod can rotate around its vertical axis to selectively lift the first pressure limiting valve and / or the second pressure limiting valve.

With the above structure, the lifting member is first used to drive the rotating rod to rotate in the first lifting state so that the rotating rod is aligned with the first push rod and / or the second push rod, and then the lifting member is used to drive the rotating rod to rise in the second lifting state, and finally the first pressure limiting valve and / or the second pressure limiting valve are lifted.
[0012] Further, the push plate has a first push plate rib and a second push plate rib; when one of the plurality of blocking ribs is located between the first push rod and the first push plate rib, the push plate lifts the first push rod through the first push plate rib and the blocking rib; when one of the plurality of blocking ribs is located between the second push rod and the second push plate rib, the push plate lifts the second push rod through the second push plate rib and the blocking rib; when one of the plurality of blocking ribs is located between the first push rod and the first push plate rib, and one of the plurality of blocking ribs is located between the second push rod and the second push plate rib, the push plate lifts the first push rod through the first push plate rib and the blocking rib, and at the same time, the push plate lifts the second push rod through the second push plate rib and the blocking rib.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0034] like Figures 1 to 8 As shown, an embodiment of the utility model provides an upper cover, which includes a cover body 10, a first pressure limiting valve 21, a second pressure limiting valve 22 and a lifting member 30. The cover body 10 is provided with a first exhaust pipe and a second exhaust pipe. The first pressure limiting valve 21 is provided on the first exhaust pipe, and the second pressure limiting valve 22 is provided on the second exhaust pipe. The lifting member 30 is movably provided on the cover body 10, and the lifting member 30 has a separation state separated from the first pressure limiting valve 21 and the second pressure limiting valve 22 and a lifting state capable of lifting the first pressure limiting valve 21 and / or the second pressure limiting valve 22.
[0035] The upper cover provided in this embodiment is applied, because the lifting member 30 has a separation state separated from the first pressure limiting valve 21 and the second pressure limiting valve 22 and a lifting state capable of lifting the first pressure limiting valve 21 and / or the second pressure limiting valve 22. That is, the lifting member 30 can lift the first pressure limiting valve 21, or lift the second pressure limiting valve 22, or lift the first pressure limiting valve 21 and the second pressure limiting valve 22 at the same time. When the cooking utensil needs to be exhausted, according to the exhaust demand, if the exhaust volume demand is not very large, the lifting member 30 can be used to lift the first pressure limiting valve 21 or the second pressure limiting valve 22 for exhaust. If the exhaust volume demand is relatively large, the lifting member 30 can be used to lift the first pressure limiting valve 21 and the second pressure limiting valve 22 at the same time, so that the exhaust of the cooking utensil is more flexible. In addition, since the lifting member 30 can lift the first pressure limiting valve 21 and the second pressure limiting valve 22 at the same time, the exhaust efficiency can also be improved.
[0036] Moreover, compared with the exhaust structure that can only lift two pressure limiting valves at the same time, for some specific foods, the exhaust volume of the exhaust structure that can only lift two pressure limiting valves at the same time is too large, which will affect the cooking effect. However, the lifting member 30 in this embodiment has three ways to lift the two pressure limiting valves, so the above problem will not occur.
[0037] It should be noted that the lifting member 30 is movably disposed on the cover body 10 , including the following two structures: the first is that the entire structure of the lifting member 30 is movable, and the second is that part of the structure of the lifting member 30 is movable.
[0038] like Figures 1 to 3 As shown, the lifting member 30 includes a rotating rod 31 movably arranged in the vertical direction, and the rotating rod 31 can rotate around its vertical axis to selectively lift the first pressure limiting valve 21 and / or the second pressure limiting valve 22. The first pressure limiting valve 21 and / or the second pressure limiting valve 22 is selected by rotating the rotating rod 31, which has the advantages of simple selection logic and easy operation.
[0039] In this embodiment, the rotating rod 31 is located below the first pressure limiting valve 21 and the second pressure limiting valve 22. The rotating rod 31 is located below the first pressure limiting valve 21 and the second pressure limiting valve 22, including the following two structures: the first structure is that the rotating rod 31 is located directly below the first pressure limiting valve 21 and the second pressure limiting valve 22, and the second structure is that the rotating rod 31 is located obliquely below the first pressure limiting valve 21 and the second pressure limiting valve 22.
[0040] Specifically, the lifting member 30 further includes a first push rod 32 and a second push rod 33 which are movably arranged in the vertical direction. The first push rod 32 is located below the first pressure limiting valve 21 and can lift the first pressure limiting valve 21. The second push rod 33 is located below the second pressure limiting valve 22 and can lift the second pressure limiting valve 22. The rotating rod 31 is rotatably arranged to selectively lift the first push rod 32 and / or the second push rod 33. By arranging the first push rod 32 and the second push rod 33, it is convenient to realize the transmission between the rotating rod 31 and the pressure limiting valve. When the rotating rod 31 lifts the first push rod 32, the first push rod 32 can lift the first pressure limiting valve 21. When the rotating rod 31 lifts the second push rod 33, the second push rod 33 can lift the second pressure limiting valve 22. When the rotating rod 31 lifts the first push rod 32 and the second push rod 33 at the same time, the first pressure limiting valve 21 and the second pressure limiting valve 22 can be lifted at the same time.
[0041] In this embodiment, the rotating rod 31 is rotatably disposed below the first push rod 32 and the second push rod 33 .
[0042] like Figure 3 As shown, a plurality of retaining ribs 311 are provided on the outer side wall of the rotating rod 31 , and the plurality of retaining ribs 311 are arranged at intervals along the circumference of the rotating rod 31 . The rotating rod 31 selectively lifts the first push rod 32 and / or the second push rod 33 through the retaining ribs 311 .
[0043] When one of the plurality of retaining ribs 311 is aligned with the first push rod 32, the rotating rod 31 moves upward, and the rotating rod 31 can lift the first pressure limiting valve 21 through the first push rod 32. When one of the plurality of retaining ribs 311 is aligned with the second push rod 33, the rotating rod 31 moves upward, and the rotating rod 31 can lift the second pressure limiting valve 22 through the second push rod 33. When two of the plurality of retaining ribs 311 are aligned with the first push rod 32 and the second push rod 33, respectively, the rotating rod 31 moves upward, and the rotating rod 31 can lift the first pressure limiting valve 21 and the second pressure limiting valve 22 at the same time.
[0044] like Figure 6 As shown, the lifting member 30 further includes a push plate 34 movably arranged in the vertical direction, and the push plate 34 has a first lifting state and a second lifting state. When the push plate 34 moves vertically in the first lifting state, the push plate 34 drives the rotating rod 31 to rotate, and when the push plate 34 moves vertically in the second lifting state, the push plate 34 lifts the rotating rod 31 to lift the first push rod 32 and / or the second push rod 33. With the above structure, the lifting member 30 is first used to drive the rotating rod 31 to rotate in the first lifting state so that the rotating rod 31 is aligned with the first push rod 32 and / or the second push rod 33, and then the lifting member 30 is used to drive the rotating rod 31 to rise in the second lifting state, and finally the first pressure limiting valve 21 and / or the second pressure limiting valve 22 are lifted.
[0045] The push plate 34 has a first push plate rib 341 and a second push plate rib 342. When one of the plurality of blocking ribs 311 is located between the first push rod 32 and the first push plate rib 341, the push plate 34 lifts the first push rod 32 through the first push plate rib 341 and the blocking rib 311. When one of the plurality of blocking ribs 311 is located between the second push rod 33 and the second push plate rib 342, the push plate 34 lifts the second push rod 33 through the second push plate rib 342 and the blocking rib 311. When one of the plurality of blocking ribs 311 is located between the first push rod 32 and the first push plate rib 341, and one of the plurality of blocking ribs 311 is located between the second push rod 33 and the second push plate rib 342, the push plate 34 lifts the first push rod 32 through the first push plate rib 341 and the blocking rib 311, and at the same time, the push plate 34 lifts the second push rod 33 through the second push plate rib 342 and the blocking rib 311. By providing the first push plate rib 341 and the second push plate rib 342 on the push plate 34, the first push plate rib 341, the second push plate rib 342 and the plurality of retaining ribs 311 cooperate with each other, thereby facilitating the push plate 34 to cooperate with the first push rod 32 and the second push rod 33 respectively.
[0046] In this embodiment, the first push rod 32 is provided with a first push rod rib 321, the second push rod 33 is provided with a second push rod rib 331, and the push plate 34 has a first push plate rib 341 located directly below the first push rod rib 321 and a second push plate rib 342 located directly below the second push rod rib 331. By providing the first push rod rib 321 on the first push rod 32 and the second push rod rib 331 on the second push rod 33, it is convenient for the rotating rod 31 to cooperate with the push rod and drive through the blocking rib 311.
[0047] When one of the plurality of retaining ribs 311 is located between the first push pin rib 321 and the first push plate rib 341, the push plate 34 lifts the first push pin 32 through the first push plate rib 341, the retaining rib 311 and the first push pin rib 321. When one of the plurality of retaining ribs 311 is located between the second push pin rib 331 and the second push plate rib 342, the push plate 34 lifts the second push pin 33 through the second push plate rib 342, the retaining rib 311 and the second push pin rib 331. When one of the multiple blocking ribs 311 is located between the first push rod rib 321 and the first push plate rib 341, and one of the multiple blocking ribs 311 is located between the second push rod rib 331 and the second push plate rib 342, the push plate 34 lifts the first push rod 32 through the first push plate rib 341, the blocking rib 311 and the first push rod rib 321, and at the same time, the push plate 34 lifts the second push rod 33 through the second push plate rib 342, the blocking rib 311 and the second push rod rib 331.
[0048] like Figure 7 As shown, the lifting member 30 also includes a rotating rod seat 40, which is fixedly arranged on the cover body 10, and the rotating rod 31 is inserted through the rotating rod seat 40. A sliding claw matching structure is arranged between the push plate 34, the rotating rod seat 40 and the rotating rod 31, so that the push plate 34 drives the rotating rod 31 to rotate during the vertical movement. With the above structure, the rotating rod 31 will rotate once and lift the pressure limiting valve once every two times the push plate 34 is lifted. In addition, the driving / transmission method through the sliding claw matching structure has the advantages of high structural stability and convenient switching, which is convenient for realizing the top push selection of the first pressure limiting valve 21 and the second pressure limiting valve 22 through the mechanical structure.
[0049] Specifically, the rotating rod seat 40 has a first cylinder 41, the push plate 34 has a second cylinder 343, and the sliding claw matching structure includes a first inclined rib 51, a second inclined rib 52 and a third inclined rib 53 that match each other. The first inclined rib 51 is arranged on the inner side wall of the first cylinder 41, the second inclined rib 52 is arranged on the upper end wall of the second cylinder 343, and the third inclined rib 53 is arranged on the outer side wall of the rotating rod 31. Since the sliding claw matching structure is a transmission structure of a push-type ballpoint pen in the prior art, it will not be described in detail here.
[0050] like Figure 1 As shown, another embodiment of the utility model provides a cooking utensil, which includes a pot body 70 and an upper cover, which can be opened and closed and is arranged on the top of the pot body 70, and the upper cover is the upper cover provided above. Therefore, when the cooking utensil needs to be vented, the cooking utensil can also flexibly lift the first pressure limiting valve 21 and / or the second pressure limiting valve 22 to vent according to the exhaust demand, so that the exhaust method of the cooking utensil is more flexible. In addition, since the lifting member 30 can lift the first pressure limiting valve 21 and the second pressure limiting valve 22 at the same time, the exhaust efficiency can also be improved.
[0051] In this embodiment, the cooking appliance comprises an electric pressure cooker.
[0052] like Figure 8 As shown, the cooking appliance further comprises a solenoid valve 60 disposed on the pot body 70, and a push rod of the solenoid valve 60 is drivingly connected to the lifting member 30 of the upper cover. The solenoid valve 60 is used to drive the lifting member 30 to move, which has the advantages of simple structure and low cost.
[0053] Specifically, the push rod of the solenoid valve 60 is drivingly connected to the push plate 34 of the lifting member 30 , and the lower end of the push plate 34 is provided with a top head 344 that cooperates with the push rod of the solenoid valve 60 .
[0054] In order to facilitate understanding of the device provided in this embodiment, the following is an explanation in conjunction with specific operations:
[0055] When exhaust is required, the solenoid valve 60 is actuated, and the push rod of the solenoid valve 60 pushes up the top 344 on the push plate 34 to move it upward, and the inclined ribs on the push plate 34 push up the inclined ribs on the rotating rod 31 to rotate the rotating rod 31 (because the inclined surface will slide when it touches the inclined surface).
[0056] In the first case, when the retaining rib 311 on the rotating rod 31 rotates to the bottom of the first push rod rib 321 of the first push rod 32, the solenoid valve 60 pushes again, and the first push plate rib 341 on the push plate 34 will lift up the retaining rib 311 on the rotating rod 31, and the retaining rib 311 will push the first push rod rib 321 of the first push rod 32, and the first push rod 32 will push the first pressure limiting valve 21 to exhaust.
[0057] In the second case, when the retaining rib 311 on the rotating rod 31 rotates to the bottom of the second push rod rib 331 of the second push rod 33, the solenoid valve 60 pushes again, and the second push plate rib 342 on the push plate 34 will lift up the retaining rib 311 on the rotating rod 31, and the retaining rib 311 pushes the second push rod rib 331 of the second push rod 33, and the second push rod 33 pushes the second pressure limiting valve 22 to exhaust.
[0058] In the third case, when the retaining rib 311 on the rotating rod 31 rotates to below the first push rod rib 321 of the first push rod 32, the retaining rib 311 on the rotating rod 31 rotates to below the second push rod rib 331 of the second push rod 33. The electromagnetic valve 60 is pushed again to exhaust the two pressure limiting valves at the same time.
[0059] Furthermore, because the retaining ribs 311 on the rotating rod 31 are distributed on a circle, the positions of the retaining ribs 311 can be adjusted as needed.
[0060] It should be noted that, the “multiple” in this embodiment includes two or more than two.
