Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and more specifically, to a lid assembly and a cooking appliance having the same. Background Art

[0002] Cooking appliances are indispensable kitchen equipment in daily life. Cooking appliances are used to prepare and cook various foods. A cooking appliance includes a pot body and a lid assembly. The lid assembly is detachably disposed on the pot body. The pot body is used to hold food. When the lid assembly is fastened to the pot body, the lid assembly can retain the heat and steam inside the pot body, promoting uniform cooking of the food by the cooking appliance.

[0003] In the related art, a cooking appliance includes a lid assembly and a pot body. When the cooking appliance performs pressure cooking, the lid assembly covers the pot body and is fastened to the pot body. High-temperature and high-pressure gas will be generated inside the cooking appliance to perform pressure cooking on the food inside the cooking appliance.

[0004] However, when the temperature inside the pot body is relatively high, the air pressure inside the pot body rises, making it difficult to fasten the lid assembly to the pot body. Summary of the Utility Model

[0005] The utility model provides a lid assembly and a cooking appliance having the same, so as to solve the problem in the related art that when the temperature inside the pot body is relatively high, it is difficult to fasten the lid assembly to the pot body.

[0006] According to an aspect of the utility model, a lid assembly is provided, which is covered on a pot body. The lid assembly includes: an outer lid; an inner lid having a lid tooth that cooperates with the pot tooth of the pot body. The inner lid is rotatably disposed below the outer lid and has a locking position where the lid tooth is fastened to the pot tooth and an unlocking position where the lid tooth is separated from the pot tooth; an opening lid assembly disposed on the outer lid. The opening lid assembly includes a driving member and a transmission member. The driving member drives the transmission member to move relative to the outer lid, and the transmission member drives the inner lid to rotate between the locking position and the unlocking position; a pressure limiting assembly including an exhaust pipe and a pressure limiting valve. The exhaust pipe passes through the outer lid and the inner lid, and the pressure limiting valve is floatingly disposed at the upper end of the exhaust pipe; wherein, the lid assembly further includes a pushing member. The pushing member and the exhaust pipe are both disposed on the outer lid. The pushing member is movable relative to the outer lid. When the transmission member drives the inner lid to rotate to the unlocking position, the transmission member drives the pushing member to lift the pressure limiting valve. When the transmission member drives the inner lid to rotate to the locking position, the pushing member releases the pressure limiting valve.

[0007] By applying the technical solution of the utility model, the cover assembly includes an outer cover, an inner cover, a cover opening assembly and a pressure limiting assembly. In the process of buckling the cover assembly on the pot body, the driving member is first used to drive the transmission member to switch the inner cover to the unlocking position. At this time, the transmission member drives the pushing member to lift the pressure limiting valve, and then the cover assembly is placed on the pot body, so that the interior of the pot body can be connected to the outside through the exhaust pipe. Even if the temperature inside the pot body is high, the exhaust can be discharged through the exhaust pipe to avoid excessive air pressure inside the pot body, which is convenient for the inner cover to be buckled with the pot body. The driving member is used to drive the transmission member to switch the inner cover to the locking position. At this time, the cover teeth are buckled with the pot teeth, and the pushing member releases the pressure limiting valve to pressure cook the food in the cooking utensil. When the cover assembly is placed on the pot body and the inner cover is in the locked position, the inner cover will float up and down relative to the outer cover as the internal pressure of the cooking utensil changes. Since the exhaust pipe and the push piece of this embodiment are both arranged on the outer cover, the change of the lifting stroke required by the push piece is avoided during the floating process of the inner cover, thereby improving the reliability of the matching between the push piece and the pressure limiting valve. In addition, the exhaust pipe and the push piece are arranged on the outer cover, so as to avoid affecting the matching relationship between the transmission part, the push piece and the pressure limiting valve when the inner cover is disassembled relative to the outer cover.

[0008] Furthermore, the push member includes a connecting rod and a push rod, the middle part of the connecting rod and the middle part of the push rod are both hinged to the outer cover, the transmission member is drivingly connected to the first end of the connecting rod, the second end of the connecting rod is drivingly connected to the first end of the push rod, and the second end of the push rod is drivingly connected to the pressure limiting valve. The above connecting rod and push rod are adopted to make the layout of the push member more flexible. Specifically, when the transmission member drives the inner cover to rotate to the unlocking position, the transmission member lifts the first end of the connecting rod, so that the second end of the connecting rod presses down the first end of the push rod, so that the second end of the push rod lifts the pressure limiting valve. When the transmission member drives the inner cover to rotate to the locking position, the transmission member presses down the first end of the connecting rod, so that the second end of the connecting rod tilts up and separates from the first end of the push rod. Under the gravity of the pressure limiting valve, the pressure limiting valve presses down the second end of the push rod.

[0009] Furthermore, the pressure limiting assembly further comprises a solenoid valve, which is arranged on the outer cover and is drivingly connected to the first end of the push rod. When the cover assembly is covered on the pot body and the inner cover is in a locked position, the solenoid valve is drivingly connected to the first end of the push rod, so that the second end of the push rod is driven by the solenoid valve to lift the pressure limiting valve or separate from the pressure limiting valve, so that during and before and after the pressure cooking of the cooking appliance, the solenoid valve, the push rod and the pressure limiting valve cooperate to change the connection state between the exhaust pipe and the outside world, thereby enriching the cooking method of pressure cooking.

[0010] Further, the first end of the connecting rod is located on the side of the hinge axis of the connecting rod and the outer cover close to the pressure limiting valve, and the second end of the ejector rod is located on the side of the hinge axis of the ejector rod and the outer cover close to the pressure limiting valve. With the connecting rod, the ejector rod and the pressure limiting valve arranged in the above layout, the distance between the first end of the connecting rod and the second end of the ejector rod can be reduced, making the layout among the connecting rod, the ejector rod and the pressure limiting valve more compact.

[0011] Further, the transmission member has a push block and a transmission inclined surface arranged at intervals in its moving direction, and the transmission inclined surface extends in the direction away from the connecting rod in the up-down direction; wherein, when the transmission member drives the inner cover to rotate to the unlocking position, the transmission member jacks up the first end of the connecting rod through the push block, and when the transmission member drives the inner cover to rotate to the locking position, the transmission member presses down the first end of the connecting rod through the transmission inclined surface. When the transmission member drives the inner cover to rotate to the unlocking position, move the transmission member along the direction from the push block to the transmission inclined surface, and the push block moves below the connecting rod to below the first end of the connecting rod, and the push block jacks up the first end of the connecting rod. When the transmission member drives the inner cover to rotate to the locking position, move the transmission member along the direction from the transmission inclined surface to the push block, and the push block moves below the connecting rod to move away from the first end of the connecting rod. At this time, the transmission inclined surface moves to the first end of the connecting rod, and the transmission inclined surface contacts and presses down the first end of the connecting rod.

[0012] Further, a guiding inclined surface is arranged at one end of the push block facing the transmission inclined surface, and the guiding inclined surface extends in the direction approaching the transmission inclined surface in the up-down direction. During the process of the transmission member driving the inner cover to rotate from the locking position to the unlocking position, the lower end of the guiding inclined surface first contacts the first end of the connecting rod, and then the transmission member moves to the upper end of the guiding inclined surface contacting the first end of the connecting rod, so that the first end of the connecting rod is jacked up under the guiding action of the guiding inclined surface; and / or, a pushing convex platform is arranged on the upper surface of the end of the push block away from the transmission inclined surface. When the transmission member drives the inner cover to rotate to the unlocking position, the first end of the connecting rod abuts and cooperates with the pushing convex platform to increase the jacking distance of the push block to the first end of the connecting rod and the jacking distance of the ejector rod to the pressure limiting valve.

[0013] Further, a connecting rod inclined surface matched with the transmission inclined surface is arranged at the first end of the connecting rod. By arranging the connecting rod inclined surface at the first end of the connecting rod, when the transmission member presses down the first end of the connecting rod through the transmission inclined surface, the transmission inclined surface and the connecting rod inclined surface are in sliding fit, so that the first end of the connecting rod swings downward smoothly.

[0014] Further, the connecting rod and the ejector rod are arranged at intervals in the transverse direction, and a rib extending in the transverse direction is arranged at the first end of the ejector rod, and the second end of the connecting rod is pressed on the rib. With the above structure, only by making the second end of the connecting rod located above the rib, the requirement that the second end of the connecting rod presses down the first end of the ejector rod can be met, reducing the height space occupied by the connecting rod and the ejector rod on the cover body, and making the structure of the cover body assembly compact.

[0015] Further, the driving member is a handle, and the handle is rotatably arranged on the outer cover to drive the transmission member to translate relative to the outer cover. The user can rotate the handle arranged on the outer cover to conveniently drive the transmission member to translate relative to the outer cover; and / or, the outer cover includes a face cover and a lining arranged below the face cover, and both the exhaust pipe and the pushing member are arranged on the lining. The face cover can be used to shield the lining, the transmission member and the pushing member arranged on the lining.

[0016] According to another aspect of the present invention, there is provided a cooking appliance, which includes: a pot body; a cover assembly that can be opened and closed to cover the pot body, and the cover assembly is the cover assembly provided above. During the process of buckling the cover assembly onto the pot body, first, the driving member is used to drive the transmission member to switch the inner cover to the unlocking position. At this time, the transmission member drives the pushing member to lift the pressure limiting valve, and then the cover assembly is covered on the pot body, so that the inside of the pot body can communicate with the outside through the exhaust pipe. Even if the temperature inside the pot body is relatively high, it can be exhausted through the exhaust pipe, avoiding excessive air pressure inside the pot body and facilitating the buckling of the inner cover and the pot body. Then, the driving member is used to drive the transmission member to switch the inner cover to the locking position. At this time, the cover teeth and the pot teeth are buckled together, and the pushing member releases the pressure limiting valve to perform pressure cooking on the food in the cooking appliance.

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Such as Figures 1 to 10As shown in the figure, an embodiment of the present utility model provides a cover assembly. The cover assembly is covered on a pot body. The cover assembly includes an outer cover 10, an inner cover 20, an opening cover assembly 30, and a pressure limiting assembly 40. The inner cover 20 has a cover tooth 21 that cooperates with the pot tooth of the pot body. The inner cover 20 is rotatably arranged below the outer cover 10 and has a locking position where the cover tooth 21 is engaged with the pot tooth and an unlocking position where the cover tooth 21 is separated from the pot tooth. The opening cover assembly 30 is arranged on the outer cover 10. The opening cover assembly 30 includes a driving member and a transmission member 31. The driving member drives the transmission member 31 to move relative to the outer cover 10. The transmission member 31 drives the inner cover 20 to rotate between the locking position and the unlocking position. The pressure limiting assembly 40 includes an exhaust pipe 41 and a pressure limiting valve 42. The exhaust pipe 41 passes through the outer cover 10 and the inner cover 20. The pressure limiting valve 42 is floatingly arranged at the upper end of the exhaust pipe 41. Wherein, the cover assembly further includes a pushing member 11. Both the pushing member 11 and the exhaust pipe 41 are arranged on the outer cover 10. The pushing member 11 is movable relative to the outer cover 10. When the transmission member 31 drives the inner cover 20 to rotate to the unlocking position, the transmission member 31 drives the pushing member 11 to lift the pressure limiting valve 42. When the transmission member 31 drives the inner cover 20 to rotate to the locking position, the pushing member 11 releases the pressure limiting valve 42.

[0035] When applying the cover assembly provided by this embodiment, the cover assembly includes an outer cover 10, an inner cover 20, an opening cover assembly 30, and a pressure limiting assembly 40. During the process of buckling the cover assembly on the pot body, first, use the driving member to drive the transmission member 31 to switch the inner cover 20 to the unlocking position. At this time, the transmission member 31 drives the pushing member 11 to lift the pressure limiting valve 42. Then cover the cover assembly on the pot body so that the inside of the pot body can communicate with the outside through the exhaust pipe 41. Even if the temperature inside the pot body is relatively high, it can be exhausted through the exhaust pipe 41 to avoid excessive air pressure inside the pot body and facilitate the buckling of the inner cover and the pot body. Use the driving member to drive the transmission member 31 to switch the inner cover 20 to the locking position. At this time, the cover tooth 21 is engaged with the pot tooth, and the pushing member 11 releases the pressure limiting valve 42 to perform pressure cooking on the food in the cooking appliance.

[0036] Moreover, during the process of opening the cover of the cooking appliance, first, use the driving member to drive the transmission member 31 to switch the inner cover 20 to the unlocking position, separate the cover tooth 21 and the pot tooth, and the pushing member 11 lifts the pressure limiting valve 42 so that the high-pressure gas inside the pot body can be discharged through the exhaust pipe 41, reducing the air pressure inside the pot body to reduce the pressure difference between the inside and outside of the cooking appliance and improving the operation safety during the cover opening process.

[0037] In addition, when the cover assembly is covered on the pot body and the inner cover 20 is in the locked position, as the internal pressure of the cooking appliance changes, the inner cover 20 will float up and down relative to the outer cover 10. Since the exhaust pipe 41 and the pushing member 11 of this embodiment are both provided on the outer cover 10, during the floating process of the inner cover 20, the change in the lifting stroke required by the pushing member 11 is avoided, and the cooperation reliability between the pushing member 11 and the pressure limiting valve 42 is improved. Moreover, by arranging the exhaust pipe 41 and the pushing member 11 on the outer cover 10, when disassembling and assembling the inner cover 20 relative to the outer cover 10, the cooperation relationship between the transmission member 31, the pushing member 11 and the pressure limiting valve 42 is not affected.

[0038] It should be noted that the exhaust pipe 41 passes through the outer cover 10 and the inner cover 20, including the following two structures:

[0039] (1) The exhaust pipe 41 is fixed on the outer cover 10 (the inner lining of the outer cover);

[0040] (2) The exhaust pipe 41 is fixed on the inner cover 20.

[0041] Moreover, the driving member drives the transmission member 31 to move relative to the outer cover 10, including at least the following two structures:

[0042] (1) The driving member drives the transmission member 31 to translate relative to the outer cover 10;

[0043] (2) The driving member drives the transmission member 31 to rotate relative to the outer cover 10.

[0044] Among them, the pushing member 11 includes the following two structures:

[0045] (1) The pushing member 11 includes a push rod. The middle of the push rod is hinged to the outer cover 10. The transmission member 31 is drivingly connected to the first end of the push rod, and the second end of the push rod is drivingly connected to the pressure limiting valve. When the transmission member 31 drives the inner cover 20 to rotate to the unlocking position, the transmission member 31 presses down the first end of the push rod, so that the second end of the push rod lifts the pressure limiting valve 42. When the transmission member 31 drives the inner cover 20 to rotate to the locking position, the transmission member 31 is separated from the first end of the push rod. Under the action of the gravity of the pressure limiting valve 42, the pressure limiting valve 42 presses down the second end of the push rod;

[0046] (2) The pusher 11 includes a connecting rod and a push rod. The middle parts of both the connecting rod and the push rod are hinged to the outer cover. The transmission member is drivingly connected to the first end of the connecting rod. The second end of the connecting rod is drivingly connected to the first end of the push rod. The second end of the push rod is drivingly connected to the pressure limiting valve. When the transmission member 31 drives the inner cover 20 to rotate to the unlocking position, the transmission member 31 jacks up the first end of the connecting rod, causing the second end of the connecting rod to press down the first end of the push rod, so that the second end of the push rod jacks up the pressure limiting valve 42. When the transmission member 31 drives the inner cover 20 to rotate to the locking position, the transmission member 31 presses down the first end of the connecting rod, causing the second end of the connecting rod to tilt up and separate from the first end of the push rod. Under the action of the gravity of the pressure limiting valve 42, the pressure limiting valve 42 presses down the second end of the push rod.

[0047] As Figures 1 to 9 shown, the pusher 11 includes a connecting rod 111 and a push rod 112. The middle parts of both the connecting rod 111 and the push rod 112 are hinged to the outer cover 10. The transmission member 31 is drivingly connected to the first end of the connecting rod 111. The second end of the connecting rod 111 is drivingly connected to the first end of the push rod 112. The second end of the push rod 112 is drivingly connected to the pressure limiting valve 42. By adopting the above-mentioned connecting rod 111 and push rod 112, the layout of the pusher 11 is more flexible. Specifically, when the transmission member 31 drives the inner cover 20 to rotate to the unlocking position, the transmission member 31 jacks up the first end of the connecting rod 111, causing the second end of the connecting rod 111 to press down the first end of the push rod 112, so that the second end of the push rod 112 jacks up the pressure limiting valve 42. When the transmission member 31 drives the inner cover 20 to rotate to the locking position, the transmission member 31 presses down the first end of the connecting rod 111, causing the second end of the connecting rod 111 to tilt up and separate from the first end of the push rod 112. Under the action of the gravity of the pressure limiting valve 42, the pressure limiting valve 42 presses down the second end of the push rod 112.

[0048] It should be noted that the middle part of the connecting rod 111 refers to the part of the connecting rod 111 except its two ends, and the middle part of the push rod 112 refers to the part of the push rod 112 except its two ends. By hinging the middle parts of the connecting rod 111 and the push rod 112 to the outer cover 10, it is convenient to realize the lever pushing effect.

[0049] In this embodiment, the pressure limiting assembly 40 further includes a solenoid valve. The solenoid valve is arranged on the outer cover 10 and is drivingly connected to the first end of the push rod 112. When the cover assembly is covered on the pot body and the inner cover 20 is in the locking position, by using the driving connection between the solenoid valve and the first end of the push rod 112, the second end of the push rod 112 is driven by the solenoid valve to jack up the pressure limiting valve 42 or separate from the pressure limiting valve 42. Thus, during and before and after the pressure cooking process of the cooking appliance, by cooperating with the solenoid valve, the push rod 112 and the pressure limiting valve 42, the communication state between the exhaust pipe 41 and the outside is changed, thereby enriching the cooking methods of pressure cooking.

[0050] As Figure 2 andFigure 5 As shown, the outer cover 10 has a solenoid valve placement position 14, and the solenoid valve is placed at the solenoid valve placement position 14.

[0051] As Figure 4 and Figure 7 shown, the first end of the connecting rod 111 is located on the side of the hinge axis of the connecting rod 111 and the outer cover 10 close to the pressure limiting valve 42, and the second end of the push rod 112 is located on the side of the hinge axis of the push rod 112 and the outer cover 10 close to the pressure limiting valve 42. With the connecting rod 111, the push rod 112 and the pressure limiting valve 42 arranged in the above layout, the distance between the first end of the connecting rod 111 and the second end of the push rod 112 can be reduced, making the layout among the connecting rod 111, the push rod 112 and the pressure limiting valve 42 more compact.

[0052] As Figure 8 and Figure 9 shown, the middle part of the pushing member 11 has a second hinge axis 1112, and the middle part of the push rod 112 has a first hinge axis 1123. Both the first hinge axis 1123 and the second hinge axis 1112 are perpendicular to the up and down direction of the cover assembly. The pushing member 11 is hinged to the outer cover 10 through the first hinge axis 1123, and the push rod 112 is hinged to the outer cover 10 through the second hinge axis 1112.

[0053] As Figures 2 to 7 and Figure 10 shown, the transmission member 31 has a push block 311 and a transmission inclined surface 312 arranged at intervals in its moving direction. The transmission inclined surface 312 extends in the direction away from the connecting rod 111 in the up and down direction. Among them, when the transmission member 31 drives the inner cover 20 to rotate to the unlocking position, the transmission member 31 jacks up the first end of the connecting rod 111 through the push block 311. When the transmission member 31 drives the inner cover 20 to rotate to the locking position, the transmission member 31 presses down the first end of the connecting rod 111 through the transmission inclined surface 312. When the transmission member 31 drives the inner cover 20 to rotate to the unlocking position, move the transmission member 31 in the direction from the push block 311 to the transmission inclined surface 312. The push block 311 moves below the connecting rod 111 to below the first end of the connecting rod 111, and the push block 311 jacks up the first end of the connecting rod 111. When the transmission member 31 drives the inner cover 20 to rotate to the locking position, move the transmission member 31 in the direction from the transmission inclined surface 312 to the push block 311. The push block 311 moves below the connecting rod 111 to move away from the first end of the connecting rod 111. At this time, the transmission inclined surface 312 moves to the first end of the connecting rod 111, and the transmission inclined surface 312 contacts and presses down the first end of the connecting rod 111.

[0054] As Figure 4 and Figure 10As shown, a guiding inclined surface 3111 is provided at one end of the pushing block 311 facing the transmission inclined surface 312, and the guiding inclined surface 3111 extends in the direction approaching the transmission inclined surface 312 in the up-down direction. During the process of the transmission member 31 driving the inner cover 20 to rotate from the locked position to the unlocked position, the lower end of the guiding inclined surface 3111 first contacts the first end of the connecting rod 111, and then the transmission member 31 moves to the upper end of the guiding inclined surface 3111 contacting the first end of the connecting rod 111, so that the first end of the connecting rod 111 is lifted under the guiding action of the guiding inclined surface 3111.

[0055] As Figure 4 and Figure 10 shown, a pushing boss 3112 is provided on the upper surface of the end of the pushing block 311 away from the transmission inclined surface 312. When the transmission member 31 drives the inner cover 20 to rotate to the unlocked position, the first end of the connecting rod 111 abuts and cooperates with the pushing boss 3112 to increase the lifting distance of the pushing block 311 to the first end of the connecting rod 111 and the lifting distance of the push rod 112 to the pressure limiting valve 42.

[0056] As Figure 4 , Figure 7 and Figure 9 shown, a connecting rod inclined surface 1111 matching the transmission inclined surface 312 is provided at the first end of the connecting rod 111. By providing the connecting rod inclined surface 1111 at the first end of the connecting rod 111, when the transmission member 31 presses down the first end of the connecting rod 111 through the transmission inclined surface 312, the transmission inclined surface 312 and the connecting rod inclined surface 1111 are in sliding cooperation, so that the first end of the connecting rod 111 swings downward smoothly and smoothly.

[0057] As Figure 4 , Figure 7 and Figure 8 shown, the connecting rod 111 and the push rod 112 are arranged at intervals in the transverse direction, and a rib 1121 extending in the transverse direction is provided at the first end of the push rod 112, and the second end of the connecting rod 111 is pressed on the rib 1121. With the above structure, only by making the second end of the connecting rod 111 located above the rib 1121, the requirement that the second end of the connecting rod 111 presses down the first end of the push rod 112 can be met, reducing the height space occupied by the connecting rod 111 and the push rod 112 in the cover body, and making the structure of the cover body assembly compact.

[0058] As Figure 8 shown, a mating plate 1113 is provided at the second end of the connecting rod 111, and the mating plate 1113 is pressed on the rib 1121.

[0059] As Figure 4 , Figure 7 and Figure 8As shown, the second end of the push rod 112 is provided with a convex point 1122 that abuts against the pressure limiting valve 42. The convex point 1122 abuts against the pressure limiting valve 42 to prevent the pressure limiting valve 42 from being scratched when the second end of the push rod 112 lifts the pressure limiting valve 42.

[0060] In this embodiment, the driving member is a handle, which is flippably disposed on the outer cover 10 to drive the transmission member 31 to translate relative to the outer cover 10. The user flips the handle disposed on the outer cover 10 to facilitate the driving of the transmission member 31 to translate relative to the outer cover 10.
